Description

Automatically adjusted bed and adjustment method thereof

Technical field

The present invention relates to a bed, and more particularly to an automatically adjusted bed and method of adjusting the same.

Background technique

A person spends 1/3 of his life in sleep, and the quality of sleep affects people's health. Good sleep quality helps people rest adequately during sleep, restoring physical strength or recovering from illness. Poor sleep quality can make people rest badly, causing diseases such as sub-health. Only good quality beds can be used to get a good night's sleep. Under normal circumstances, the human spine has four curvatures, which are S-shaped from the side, namely cervical lordosis, thoracic kyphosis, lumbar lordosis and sacral kyphosis. That is to say, the shape of the human body has a certain curve. A good bed should be able to maintain the normal physiological curve of the human body in order to make people feel comfortable during sleep. At the same time, because of the fast pace of life, people's stress is usually very large. Many people have certain health problems in their head, neck and shoulders. The support problems of these parts are especially important during the sleep process. It is also desirable to be able to return the spine to a normal physiological curve by taking care of the head, neck and shoulders of the human body through the bed during sleep.

Nowadays, there are many health hazards in the beds on the market. Beds on the market can be divided into: hard bed, soft bed and skeleton bed. These beds have their own limitations and therefore do not provide good sleep. Please refer to Figure 1. Because the hard bed is a flat surface, when the person is lying on the bed, the human body can't fit well with the bed. The actual support points of the human body during sleep are few. The main support points are on the shoulders, hips and hips. Other parts, easy to cause poor curvature of the spine, has a great hidden danger to the spine and health. When people use a soft bed, we can see from Figure 2 that the human body and the bed are fitted together, but due to the poor supporting force of the bed, the spinal column may be improperly bent, and the health hazard is great. Patients with lumbar disc herniation cannot sleep in soft beds. The skeleton bed is a bed that is customized according to the shape of the human body. By adjusting the height of the row of skeletons, it is possible to adjust the pressure values of various parts of the body so that the pressure values of various parts of the body are in a healthy bearing value. However, since the skeleton is custom-fixed, the shape of the bed is also fixed. The person can only maintain a sleeping position while lying on the bed. If the person turns over and the like, the bed cannot fit well with the human body, and the bed is very large. Limitations. At the same time, the skeleton bed needs to be customized, and the same bed cannot be used by different people. The customization also makes the price of the bed very expensive, and the bed is limited.

Therefore, in order to get a good sleep, people need a physiological curve that can make the spine in a normal state, and even if people adopt different sleeping postures during sleep, they can adjust well and cost less. Automatically adjusted bed.

The adjustment method of the present invention will be described by taking a load cell as an example. After the bed is powered, the control unit collects the signal from the load cell. The new number issued by each load cell contains body weight information, which contains weight data. Based on the individual weight data, the control device determines if someone is sleeping on the bed. If no, return to the step of acquiring the signal. If so, it is determined from the individual weight data whether the number of people on the bed is single or double. If it is a single person, it enters the single person's sleep mode. If you are a double, enter the sleep mode for two people. In the single-person sleep mode, each weight data is used for single-person sleep data analysis processing. In the double sleep mode, each weight data is used for double sleep data analysis processing. In an embodiment of the present invention, determining whether the number of people on the bed is single or double includes: determining the ratio of the head weight to the total weight by the continuity of the weight data and the value of the weight data. . In this embodiment, determining whether the person in the bed is lying down comprises: determining two peak areas of the weight data and the spacing thereof, determining that the maximum peak area is the buttocks, and the leg weight value must be below the buttocks, and determining whether the Lying in a sleeping position.

Then, in the single or double mode, each weight data is used to determine if the person on the bed is sleeping steadily. If the person is lying on the bed, the height recognition, the weight recognition algorithm, and the body type recognition algorithm are used to identify the height, weight, and body type. Thereafter, the sleeping position recognition algorithm is used to determine the sleeping position of the person, such as lying down on the side and the like. The body part recognition algorithm is then used to identify and locate various parts of the person, such as the buttocks, waist, shoulders, head, neck and legs. Then use the hip ratio algorithm to calculate the hip adjustment, use the waist ratio algorithm to calculate the lumbar adjustment, use the shoulder ratio algorithm to calculate the shoulder adjustment, use the head-neck ratio algorithm to adjust the head and neck, and use the leg proportion algorithm to calculate the leg adjustment. Determine the distance that the support unit corresponding to each part needs to be adjusted. The muscle comfort calculation algorithm and the anti-pressure sore algorithm are then used to perform muscle comfort adjustment calculations and anti-pressure sore adjustment calculations and to determine the distances that need to be fine-tuned in certain parts. Finally, the control unit selects a control signal related to the distance adjustment, and the control signal controls each adjustment mechanism to perform an action, and adjusts the height of each support unit, such as a rising support unit or a descending support unit, so that the spine of the human body is in a normal physiological curve. After the control signal is output, the adjustment method of the present invention returns to the step of acquiring the signal. The various steps in one embodiment of the adjustment method of the present invention have been described above, but it should be noted that the order of the steps mentioned therein is not fixed, and in other embodiments, the order of the various steps may be reversed.

Because the method provided by the invention continuously collects the signal sent by the sensing unit, when the sleeping position of the person changes, the signal sent by the sensing unit also changes, and the signals are used for analysis to determine the distance that each supporting unit needs to adjust, and the signal is sent out. The control signal control adjustment mechanism adjusts the height of the support unit, so by this method, the bed provided by the present invention can provide a real-time adjustment function.

The principle of leverage can be applied both horizontally and vertically for more accurate positioning and identification. For example, for a row of supporting units composed as shown in FIG. 6, the upper part of the sensing unit causes the sensing units on both sides to generate a human body-related signal, and the weight data in the signal has a value of 10 kg, and the lever principle can determine the The location is located in the middle of the row of support units. If the value of the weight data in the signal sent by the sensing unit on the left is 5kg, and the value of the weight data in the signal sent by the sensing unit on the right is 15kg, then the distance from the part to the right edge can be judged by the principle of leverage. 25% of the length of the row. For a row of supporting units composed as shown in FIG. 5, the upper part of the position causes the signals sent by the pressed sensing unit to have different weight data values respectively, and it can be determined that the part is mainly located at the transmission with the largest weight data value.
