Description

Arrangement structure of smart watch components

technical field

The invention relates to the field of smart electronic equipment, in particular to an arrangement structure of smart watch components.

Background technique

At present, the PCB stacking of smart watches uses two sides to place components, and components are placed in the middle of both sides of the PCB and in other different areas. If the components are placed on both sides and the PCB area is not completely densely filled, the PCB area will be wasted, and the space utilization rate of the whole machine will be low. Placing components on both sides will also cause the heat generation of individual components to increase, and at the same time, the heat cannot be dissipated evenly and quickly, and the thermal design performance of the whole machine will deteriorate. Moreover, placing components on both sides does not give up the height space and the maximum area space to the battery, resulting in a small battery capacity. In the case of unreasonable stacking, it is difficult to reduce the thickness of the whole machine. Under the existing structure, the antenna is not easy to be installed on the main unit, but can only be installed on the strap, which is not conducive to flexible replacement of the strap in the later stage.

detailed description

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

As shown in Figure 1 and Figure 2, a smart watch component arrangement structure, including display assembly 1, battery 2, PCBA3 (PCBA is the abbreviation of English Printed Circuit Board+Assembly, that is to say, the empty PCB board passes through the SMT pieces), functional elements, antennas. Wherein, the functional components include a speaker 4 , a microphone 5 , a SIM card slot 6 , a sensor 7 , and a vibration motor 8 . The PCBA3 is a single-sided layout, the bottom surface of the battery 2 is against the top surface of the PCBA3, the speaker 4, the microphone 5, the SIM card slot 6, the sensor 7, and the vibration motor 8 are evenly distributed around the battery 2, and the display assembly 1 is arranged on the battery 2 on the top surface.

In this embodiment, PCBA3 is a rigid PCB. (Of course, in order to further compress the thickness of the whole machine, FPC (flexible circuit board) can also be used. When no components are placed on the FPC, the thickness of the whole machine can be further reduced.) Display component 1 selects the thinnest display component, Wherein the display drive circuit is placed parallel to or perpendicular to the plane of the display screen. The antenna is hidden under the decoration in the display assembly 1 or in the plastic casing, or the antenna is embedded in the display screen or touch screen in the display assembly 1, and the antenna can be made of transparent, translucent or opaque materials. In addition, the antenna can also be selected as a decoration in the display screen assembly 1 , so that the antenna can be hidden to a greater extent to save space. The outer surface of the battery 2 is covered with a heat-dissipating material, and its bottom surface has the largest area. The bottom surface of the battery 2 is closely attached to the top surface of the PCBA, thereby giving the battery 2 a maximum area and maximum thickness space, and increasing the battery capacity.

The top surface of the PCBA3 is closely attached to the bottom surface of the battery 2. After this surface of the PCBA3 overlaps with the battery 2, other components can be fixed on the PCBA3 or between the side wall of the battery 2 and the casing. The PCBA3 is closely attached to the top surface of the battery 2 and has a large-area exposed copper area, and the large-area exposed copper area is closely attached to the heat-conducting material.

The loudspeaker 4 and the microphone 5 are fixed between the side wall of the battery 2 and the plastic casing, without occupying the space of the battery 2 and without increasing the thickness of the whole machine. At the same time, the microphone hole can be used as a waterproof design, and the plastic structure does not occupy the internal space.

The sensor 7 is directly fixed on the PCBA3. (In addition, the sensor 7 can also be connected with the PCBA3 through FPC (flexible circuit board).) When the smart watch is worn by the human body, the SIM card slot 6 and the sensor 7 are close to the back of the human body. It is easy for users to disassemble and install the SIM card, and the SIM card cover is easy to make a waterproof design. Sensor 7 is close to people's hand, makes sensor reach best effect. The sensor 7 is directly installed on the PCBA3, the assembly is simple, the difficulty of the waterproof design is reduced, and the thickness of the whole machine will not be increased.

In another embodiment, when the smart watch is worn by the human body, the SIM card is inserted into the SIM card slot 6 from the side of the human hand, so as to facilitate the replacement of the SIM card.

The vibration motor 8 is fixed between the side wall of the battery 2 and the plastic casing, does not occupy the space of the battery, and does not increase the thickness of the whole machine. In this embodiment, it is directly placed between the side wall of the battery 2 and the plastic casing. The direct connection with the PCBA3 has the advantage of reducing the connection between the vibration motor 8 and the PCBA3 and reducing the fixing of the structure to the vibration motor 8 .

When assembling, the bottom surface of the battery 2 covered with heat dissipation material is closely attached to the top surface of the PCBA3, the display assembly 1 is installed on the structural member, and then the assembled PCBA3 and battery 2 are installed on the display assembly 1. On the structural parts, the display screen assembly 1 is located on the top surface of the battery 2, and the display screen is connected to the main board. At this time, the display screen assembly 1, the battery 2, and the PCBA 3 are all connected into one body through the structural parts. Then install other parts on the surroundings of the structural parts and the housing at the bottom of the whole machine. Finally, install the assembled components of the display screen into the bottom case of the complete machine and fix them.

The above smart watch component arrangement structure adopts the way of arranging components on one side of PCBA, the battery and PCBA are closely attached, and other components are evenly arranged around the battery, so as to realize the compression of the whole machine in thickness and reduce the cost of components. With stacking, the volume of the whole machine becomes smaller, the space utilization is better and more reasonable, the heat dissipation effect is better, and the battery volume is increased to improve the battery life.

Apparently, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation of the present invention. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here.
