When the stylus performs writing and other operations on the touch surface of the electronic device, the touch parts of the stylus, such as the pen tip, will rub against the touch surface of the electronic device. As the use time of the stylus increases, the touch The touch part of the pen is gradually worn out, and the internal metal is gradually exposed. If the operator continues to use the worn stylus without noticing the wear of the touch part and the exposed metal inside, the worn out stylus will During the writing process, the stylus will rub against the touch surface of the electronic device, so the touch mask of the electronic device has a higher risk of being scratched.

In view of this, the present application provides a touch component, a stylus using the touch component, and a stylus system including the stylus.

As shown in FIG. 1 , a touch component 100 provided according to an embodiment of the present application includes a touch body 110 , a conductor 120 and a conductive layer 130 . The touch body 110 has an accommodating cavity 110 a and a contact surface 110 b, and the contact surface 110 b is exposed to at least a part of the surface of the touch body 110 . The conductor 120 is accommodated in the accommodating cavity 110a, the conductive layer 130 is disposed on the touch body 110, the conductive layer 130 is located between the conductor 120 and the contact surface 110b, and is insulated from the conductor 120 and the contact surface 110b and arranged at intervals to conduct electricity. The layer 130 has a through hole, the projection of the electrical conductor 120 on the contact surface 110b being at least partially arranged to cover the through hole.

The touch component 100 may be a tip of a stylus, or other components that need to be in contact with a touch surface of an electronic device.

The touch body 110 can be made of insulating material, and the contact surface 110b of the touch body 110 can be the entire area of the touch body 110 exposed to the outside, or the contact surface 110b can be a part of the area of the touch body 110 exposed to the outside. The contact surface 110b can be used to contact the touch surface of the electronic device, so as to realize the writing function on the electronic device.

The conductor 120 is accommodated in the accommodating cavity 110 a of the touch body 110 , and the touch body 110 can provide a certain protection for the conductor 120 , and is beneficial to reduce the risk of the conductor 120 accidentally injuring the human body or the touch surface.

The conductor 120 may include metal or gas materials with conductive functions. When the contact surface of the touch body 110 is in contact with the touch surface of the electronic device, the conductor 120 can generate electrical signals on the corresponding area on the touch surface. The body 120 is positioned relative to the touch surface of the electronic device, and text, patterns or graphics are displayed on the corresponding position of the touch surface to complete the writing work.

The conductive layer 130 is located between the conductor 120 and the contact surface 110b, is insulated from the conductor 120 and the contact surface 110b, and is spaced apart from the conductor 120 and the contact surface 110b. The conductive layer 130 may be in the shape of a straight layer; or, the conductive layer 130 may be in the shape of an arc. Exemplarily, the conductive layer 130 may be arranged parallel to the contact surface 110b.

The conductive layer 130 has through holes, and the conductive layer 130 may be in the shape of a sheet with through holes, or the conductive layer 130 may be in the shape of filaments or strips and surround the through holes.

The through hole can be in a circular, square or other irregular shape, which is not limited here and can be selected according to actual needs.

The touch control component 100 may include one conductive layer 130 ; or, the touch control component 100 may include multiple conductive layers 130 . In an embodiment where the touch component 100 includes a conductive layer 130 , the conductive layer 130 can be arranged close to the conductor 120 to increase the wearable depth of the touch body 110 , thereby improving the service life of the touch component. In the embodiment where the touch component 100 includes multiple conductive layers 130 , the conductive layer 130 closest to the conductor 120 can be arranged close to the conductor 120 , and the wearable depth of the touch body 110 can also be increased.

The projection of the conductive layer 130 on the contact surface 110b is the projection of each region of the conductive layer 130 along the normal direction of each position of the contact surface 110b, and at least part of the projection of the conductor 120 on the contact surface 110b covers the through hole, then at least part of the conductor 120 Part of the electric signal can be transmitted with the touch surface of the electronic device through the through hole, so as to reduce the risk that the conductive layer 130 shields the conductor 120 and causes the touch component 100 to fail to work normally.

Since the conductive layer 130 is located between the conductor 120 and the contact surface 110b, as the touch component 100 is used for a longer period of time, the touch body 110 is gradually worn away, and the conductive layer 130 will be exposed and worn before the conductor 120, and the With the wear of the conductive layer 130, the circuit where the conductive layer 130 is located is disconnected or the resistance value of the conductive layer 130 changes. In this way, when the touch component 100 is applied to a stylus, the resistance value of the conductive layer 130 can The change of the wear position or the amount of wear of the conductive layer 130 is recognized by related modules inside the stylus to determine the distance between the conductor 120 and the contact surface 110b. When the resistance value of the conductive layer 130 reaches a predetermined threshold or the circuit of the conductive layer 130 is disconnected, it is determined that if it continues to be used, the conductor 120 of the touch component 100 will be exposed and directly contact the touch surface of the electronic device. . Therefore, when the resistance value of the conductive layer 130 reaches a predetermined threshold or the circuit where the conductive layer is located is disconnected, it is convenient for the operator to adjust the posture of holding the pen or replace the stylus in time, so as to reduce the exposure of the conductor 120 to the The risk of touching the outside of the component 100 and scratching the touch surface of the electronic device. Exemplarily, the stylus can remind the operator in the form of voice or prompt sound, or display patterns on the display device connected to the stylus to remind the operator of the wear information of the touch component 100 .

It can be understood that, after the touch component 100 is prepared, the predetermined threshold value of the resistance value of the conductive layer 130 can be determined through experiments.

The touch control component 100 may include a layer of conductive layer 130, or include a plurality of conductive layers 130 that are insulated from each other and connected in parallel with each other. The conductive body 120 points to the direction of the contact surface 110b. Each conductive layer 130 corresponds to different degrees of wear of the touch body 110 , which is convenient for the operator to judge the degree of wear of the touch body 110 . Certainly, a plurality of conductive layers 130 may also be arranged in parallel, and each of the plurality of conductive layers 130 may be arranged to correspond to different positions of the contact surface 110b, so as to judge wear of different positions of the touch body 110 through the conductive layers 130 .

The conductive layer 130 can cover the entire area of the conductive body 120 facing the contact surface 110b, that is, any direction from the contact surface 110b to the conductive body 120 needs to pass through the conductive layer 130, so that as the touch body 110 wears, the conductive layer 130 is exposed and worn out before the conductor 120 , any wear of the touch body 110 will expose the inner conductive layer 130 , and the degree of wear of the touch body 110 can be judged through the conductive layer 130 .

Alternatively, the conductive layer 130 may cover a part of the conductive body 120 facing the contact surface 110 b , that is, a part of the direction from the contact surface 110 b to the conductive body 120 needs to pass through the conductive layer 130 . In this way, as the contact surface 110b corresponding to the conductive layer 130 wears, the conductive layer 130 is gradually exposed and wears out. In this way, the wear degree of the touch body 110 corresponding to the threshold can be determined through the conductive layer 130 .

In the touch component 100 provided by the embodiment of the present application, the conductive layer 130 is provided between the conductor 120 and the contact surface 110b, and the conductive layer 130 is insulated from the conductor 120 and the contact surface 110b and arranged at intervals. After abrasion, the conductive layer 130 will be exposed first, and the conductive layer 130 will be worn away. When the touch component 100 is applied to a stylus, after the conductive layer 130 wears out, the resistance value of the conductive layer 130 changes or the circuit where the conductive layer 130 is located is disconnected. Control the wear degree of the main body 110, so that the operator can replace the touch component 100 or the stylus pen, and reduce the risk of the conductor 120 inside the touch component 100 being exposed and rubbing against the touch surface of the electronic device to scratch the touch surface. risk.

As shown in FIG. 2 , in some embodiments, the touch component 100 includes a multi-layer conductive layer 130 , the conductive body 120 points to the direction of the contact surface 110 b, and the multi-layer conductive layer 130 is insulated and arranged at intervals.

Optionally, the touch component 100 may include two or more conductive layers 130 . There are conductors 120 pointing to the direction of the contact surface 110b, and multiple conductive layers 130 are arranged at intervals, and respectively correspond to different wear depths of the touch body 110 .

In this way, as the touch body 110 wears, the conductive layer 130 closer to the contact surface 110b is exposed and wears first. According to the wear of different conductive layers 130 , the wear degree of the touch body 110 can be judged.

When the touch body 110 is used in a stylus, after different conductive layers 130 are disconnected, the stylus can send out different prompt information, so that the operator can judge the degree of wear of the touch body 110 . Exemplarily, after different conductive layers 130 are worn, the stylus can make different voices or prompt sounds, or display different prompt images on the touch surface of the electronic device electrically connected with the stylus.

Therefore, setting the touch component 100 to include multiple conductive layers 130 , and the multiple conductive layers 130 are insulated and arranged at intervals is beneficial for the operator to judge the degree of wear of the touch body 110 .

As shown in FIG. 2 and FIG. 3 , in some embodiments, the conductive layer 130 includes a plurality of conductive regions 130 a, the plurality of conductive regions 130 a are insulated from each other, and different conductive regions 130 a cover different regions of the conductor 120 .

The conductive layer 130 may include two, three, four or more conductive regions 130 a, and different conductive regions 130 a are arranged corresponding to different regions of the conductor 120 . Exemplarily, along the circumferential direction of the conductor 120 , the plurality of conductive regions 130 a are distributed in a fan shape. The plurality of conductive regions 130a are insulated from each other and arranged at intervals, so that the conductive regions 130a are insulated from each other, and the disconnection of any one of them will not affect the on-off of the circuits of other conductive regions 130a.

The distances between the different conductive regions 130a and the contact surface 110b can be the same. In this way, the different conductive regions 130a correspond to different wear areas of the touch body 110. According to the disconnection or resistance change of the different conductive regions 130a, it is possible to judge the wear of the touch body 110. Wear position, so as to adjust the posture of holding the pen in time, to adjust the position of the contact surface 110b that contacts with the touch surface of the electronic device and generates friction, and reduces the risk of abrasion of the contact surface between the conductor 120 and the electronic device. And when all the conductive regions 130a are disconnected, the touch component 100 or the stylus can be replaced.

Therefore, the conductive layer 130 is set to include a plurality of conductive regions 130a, and the plurality of conductive regions 130a are insulated from each other, so that different conductive regions 130a cover different regions of the conductor 120, and after part of the conductive regions 130a are worn, they can pass Adjust the posture of holding the pen and continue to use the touch component 100. In this way, while reducing the friction between the conductor 120 and the touch surface of the electronic device and reducing the risk of scratching the touch surface, it is beneficial to improve the service life of the touch component 100 .

As shown in FIG. 2 , FIG. 3 and FIG. 4 , in some embodiments, the conductive layer 130 includes metal wires 131 , and the metal wires 131 surround and form through holes, and are arranged in a mesh shape along a direction parallel to the contact surface 110 b.

The metal wire 131 has good electrical conductivity, and the through hole formed by surrounding the metal wire 131 is relatively large, which further reduces the shielding effect of the conductive layer 130 on the conductor 120 , and in the manufacturing process of the touch component 100, the metal wire 131 is relatively large. It is easy to be injection molded with the touch body 110 .

The metal wires 131 are arranged in a mesh shape, and the through holes formed by the metal wires 131 are arranged in a mesh shape. The shape of the through holes can be polygonal, circular, tricyclic or other irregular shapes, which are not limited here. actually need to be selected.

The metal wire 131 is surrounded to form a through hole, and the size of the through hole formed by the metal wire 131 should be appropriate, so that the metal wire 131 has a proper interval. After the touch body 110 wears out, if the touch body 110 in the through hole wears out before the metal wire 131, a suitable through hole is beneficial to ensure that the metal wire 131 wears out before the conductor 120, so as to realize the conductive layer 130. A circuit break occurs in time.

The metal wires 131 are arranged along a direction parallel to the contact surface 110b, and the distance from any position of the metal wires 131 to the contact surface 110b is the same. If the distance is set, the metal wire 131 will be exposed and will be worn with the touch surface of the electronic device. Therefore, the area corresponding to the contact body 110 and the metal wire 131 is relatively large, and the contact surface 110b in this area is in contact with the metal wire. 131 has a considerable distance. When the metal wire 131 is worn, the worn position and the worn state of the contact surface 110b can be determined according to the worn position or degree of the worn wire 131 .

In addition, after the metal wire 131 is disconnected, the corresponding conductive layer 130 will be more affected by the disconnection or the change of the resistance value, so as to sense the wear condition of the conductive layer 130 more sensitively.

Therefore, arranging the conductive layer 130 to include the metal wire 131 is beneficial to improve the process reliability of the touch component 100 during processing, and also facilitates the change of the resistance value of the conductive layer 130 or the disconnection of the conductive layer 130, which is more convenient. Sensitively judge the wear condition of the touch body 110 .

As shown in FIG. 4 , FIG. 5 and FIG. 6 , in some embodiments, the metal wires 131 are arranged in a rectangular grid, an annular grid or a fan-shaped annular grid.

The metal wires 131 are arranged in an array, so the metal wires 131 are arranged in an array along the extending direction of the conductive layer 130 , which does not mean that the metal wires 131 must be in a planar shape. The metal wires 131 can be arranged in a matrix array or in a circular array.

It can be understood that, whether it is a matrix-arranged rectangular grid, circular grid or fan-ring grid, the metal wires 131 can be arranged more regularly, and the metal wires 131 themselves can be guaranteed to have a certain Structural strength, reducing the phenomenon that the metal wire 131 is damaged due to collision or vibration, resulting in misjudgment.

In addition, if the metal wires 131 are arranged in a matrix, the metal wires 131 are arranged more regularly. When the wear depth of the touch body 110 in different regions is roughly the same, the metal wires 131 can achieve roughly the same amount of wear. , it is more convenient to judge the wear state of the touch body 110 according to the resistance change or disconnection of the metal wire 131 .

As shown in FIG. 7 , in some embodiments, the touch component 100 has a decoration layer 140 disposed on the touch body 110 and located between the conductor 120 and the contact surface 110b.

Optionally, the decoration layer 140 can be located between the conductor 120 and the conductive layer 130, or the decoration layer 140 can also be located between the conductive layer 130 and the contact surface 110b, which is not limited here and can be selected according to actual needs.

Optionally, the decoration layer 140 may be any structure that can be recognized by human eyes. Exemplarily, the decoration layer 140 may be a plastic film with a certain color.

By setting the decoration layer 140 and setting the decoration layer 140 between the contact surface 110b and the conductor, as the touch body 110 wears, the decoration layer 140 will be exposed before the conductor 120, because the decoration layer 140 can be recognized by human eyes. , the operator can clearly see the wear state of the touch body 110 , so as to adjust the posture of holding the pen or replace the touch component 100 in time.

Optionally, the touch control component 100 may include only one decoration layer 140, or the touch control component 100 may comprise a plurality of decoration layers 140 spaced apart from each other and having different patterns or colors, so that the operator can The color or pattern of the touch body 110 can be used to determine the wear condition of the touch body 110 .

Therefore, setting the touch component 100 to include the decoration layer 140, and setting the decoration layer 140 between the conductor 120 and the contact surface 110b, is convenient for the operator to more intuitively judge the wear state of the touch body 110, and adjust the pen holding posture or The touch component 100 is replaced to further reduce the risk of scratching the touch surface due to friction between the conductor 120 and the touch surface of the electronic device.

In some embodiments, the end of the conductor 120 facing the contact surface 110b is in the shape of an ellipsoid, and the contact surface 110b and the end of the conductor 120 facing the contact surface 110b are arranged in a conformal manner.

If the end of the conductor 120 facing the contact surface 110b is ellipsoidal, then the end of the conductor 120 for transmitting electrical signals with the touch surface of the electronic device is ellipsoidal, and the contacting surface 110b is also ellipsoidal. Large surface area, thus, the surface of the contact surface 110b used to contact the touch surface of the electronic device has a relatively large area. And in the process of contacting the contact surface 110b with the touch surface, since the contact surface 110b and the conductor 120 are arranged in conformity with one end facing the contact surface 110b, any position of the contact surface 110b is in contact with the touch surface, and the conductor 120 can be realized. Generate electrical information with the touch surface of the electronic device, so as to realize more fluent writing or touch operation on the touch surface.

Therefore, the end of the conductor 120 facing the contact surface 110b is arranged to be ellipsoidal, and the contact surface 110b and the end of the conductor 120 facing the contact surface 110b are arranged in a conformal manner, so that the touch component 100 is in use. Touch or write operations are performed on the touch surface of the device, and the contact surface 110b has a larger area in contact with the touch surface of the electronic device. In this way, when the touch component 100 is applied to a stylus, the operator has more The optional pen holding posture improves the convenience of the operator in the process of writing or touching. And because the contact surface 110b and the conductive body 120 are disposed along the side facing the contact surface 110b, changing the contact position between the contact surface 110b and the touch surface, the distance change of the conductive body 120 relative to the contact surface 110b is small, which is conducive to operation. Or maintain the fluency of writing or touching when changing the pen holding posture.

As shown in FIG. 8 , the stylus 10 provided according to the embodiment of the present application includes the touch component 100 provided in any of the above embodiments.

Optionally, the stylus 10 can be an active stylus or a passive stylus. The stylus 10 is used for writing or touch operations on the touch surface of electronic devices with touch functions such as mobile phones, tablets, notebooks, televisions or projectors. The touch component 100 can be at least part of the nib of the stylus 10. During the use of the stylus 10, the touch surface 110b of the touch component 100 is in contact with the touch surface of the electronic device. Perform operations such as writing or touching.

The stylus 10 provided by the embodiment of the present application adopts the touch component 100 provided by any of the above-mentioned embodiments. When the stylus 10 writes on the touch surface of the electronic device, as the pen tip wears out, the touch The conductive layer 130 in the control part 100 is exposed before the conductive body 120, and wears with the touch surface. After the conductive layer 130 is worn, the resistance of the conductive layer 130 changes, and the stylus 10 detects the resistance of the conductive layer 130. The change can judge the wear state of the pen tip, so as to send a prompt message before the conductor 120 in the touch component 100 is exposed or before the conductor 120 rubs against the touch surface, so as to replace the stylus 10 or the touch component 100 in time , to reduce the risk of scratching the touch surface by the conductor 120 in the touch component 100 .

Please continue to refer to FIG. 8 , in some embodiments, the stylus 10 further includes a circuit board 11 , the circuit board 11 is electrically connected to the conductive layer 130 and is used to detect the wear state of the conductive layer 130 .

The circuit board 11 can be a component with an integrated circuit such as a chip. The circuit board 11 is electrically connected to the conductive layer 130 , and the relevant circuits in the circuit board 11 and the conductive layer 130 together form a series circuit. The circuit board 11 can also be integrated with components such as a current sensor or a voltage sensor, and the wear state of the conductive layer 130 can be judged by measuring the variation of the resistance value of the conductive layer 130 .

For example, when the conductive layer 130 is worn to the point where the series circuit formed with the circuit board 11 is disconnected, it can be considered that the resistance value of the conductive layer 130 increases to infinity, and it is determined that the conductive layer 130 has been worn out and cannot be used any longer.
