Bed device and method for automatically adjusting bed surface based on sleeping posture

The present invention relates to a bed device and method. More specifically, the present invention is a bed device and method that automatically adjusts the height of the bed surface based on sleeping posture.

The health of the spine is an important factor affecting sleep quality. It is generally believed that the bed supports the sleeping position of the human body, so whether the height of the bed can maintain the health of the spine has a certain degree of influence. As the sleeping posture of the human body may change during sleep, turning from lying down (sleeping on back) to sleeping on the side or from sleeping on the side to lying down (sleeping on back) will change the support of the spine. If the support of the spine is not properly adjusted, once the sleeping position is maintained for too long, it will easily cause compression of the spinal nerves or excessive stress on the cervical muscles.

The new patent No. M570715 discloses a conventional bed set that can automatically adjust the bed surface according to sleeping posture. The conventional bed set uses a supporting layer to arrange multiple airbags at the same height. Since the human spine is S-shaped, it is generally ergonomic When the airbag is inflated and deflated, most of the shoulders need a lower height, and the waist needs a higher height, but when the airbags are all set at the same height in the bed, the airbag at the waist can only reach the height of the bed at most. On the surface, users who cannot effectively make the lumbar spine vertebral arch deeper (more S) have the lumbar support height higher than the level of the bed surface to provide the best lumbar support. At this time, it will not be possible for all users to get the best sleep quality.

In addition, in the conventional bed set, multiple pressure detection modules are arranged on the bed surface supported by multiple airbags. Since the bed surface supported by the airbags is usually flexible, the bed surface will deform due to the different sleeping positions of the user. , It is easy to affect the measurement of the pressure detection module, resulting in the problem of inaccurate measurement, and the user’s different sleeping postures cannot be correctly determined.

Please refer to Figure 5, which shows the flow chart of the bed device of the present invention that automatically adjusts the bed surface based on the sleeping position. In an embodiment of the present invention, a method for automatically adjusting the bed surface based on sleeping posture is used in a multi-layer bed body 20 of the bed device shown in the first figure. The method includes: step 101, when the user lies on the multi-layer On the bed surface of the bed body 20, according to the operation of the control panel 18, the control unit 11 records the pressure sensing of the sleeping position sensing unit 19 according to the user’s lying sleeping position and side sleeping position, and the sleeping position change process. The result is used as an adjustment parameter and stored in a memory.

In one embodiment of the present invention, regarding the sleeping position change process, when the user lies on the multi-layer bed 20 and sleeps, if the sleeping position is lying on the side, the sleeping position sensing unit 19 will detect a maximum pressure value If the sleeping position is lying flat, the sleeping position sensing unit 19 will detect two maximum pressure values, and the sleeping position sensing unit 19 can determine the user’s current sleeping position according to the number of maximum pressure values detected The state is lying flat (sleeping on the back) or lying on the side (sleeping on the side), the control unit 11 can control the inflator motor group or the air valve group to the shoulder airbag 17 according to the aforementioned sleeping posture judgment result and according to a parameter setting. Perform an inflation or deflation action with the waist airbag 16 to increase or decrease the user's shoulder or waist pressure to the optimum pressure P′.

The parameter setting includes physiological or non-physiological parameters related to the user, such as: height, weight, age, gender, etc., which can be set by the operator or set by the user through the operation of the control panel 18 to store the adjusted parameters in the memory Therefore, the control unit 11 can adjust the airbags 17, 16 according to the physiological or non-physiological parameters related to the user after judging that the user’s sleeping posture is lying on his back (sleeping on his back) or lying on his side (sleeping on the side). To the optimal softness and hardness, the user's shoulder or waist pressure can be adjusted to the optimal pressure. The following further describes the storage of adjustment parameters in steps 102 and 103.

Step 102: According to the user's lying sleeping position, according to the operation of the control panel 18, the control unit 11 controls the inflator motor group and the air valve group to inflate or deflate the shoulder airbag 17 and the waist airbag 16 to adjust the shoulder The heights of the airbag 17 and the waist airbag 16 are suitable for supporting the shoulders and waist of the user in a lying down position, and the operation result of the control panel 18 is stored in the memory as an adjustment parameter. When the user is lying flat, the required degree of deflation of the shoulder airbag 17 is relatively low. Therefore, the height of the shoulder airbag 17 when lying flat will be higher than the height when lying on the side. The operation of the control panel 18 depends on the user. The lumbar spine arch of the lumbar spine depends on the depth of the lumbar spine. If the lumbar spine arch of the user is deeper (more S), the required degree of inflation of the lumbar airbag 16 is higher (that is, the inflated height is higher). S is less obvious), the required degree of inflation of the waist airbag 16 is lower (that is, the inflation height is lower).

Step 103: According to the user's sleeping position on the side, according to the operation of the control panel 18, the control unit 11 controls the inflator motor group and the air valve group to inflate or deflate the shoulder airbag 17 and the waist airbag 16 to adjust the shoulder The heights of the airbag 17 and the waist airbag 16 are suitable for supporting the shoulders and waist of the user in a side-lying sleeping position, and the operation result of the control panel 18 is stored in the memory as an adjustment parameter. When the user is sleeping on the side, the required degree of deflation of the shoulder airbag 17 is relatively high. Therefore, the height of the shoulder airbag 17 lying on the side will be lower than the height when lying down. The operation of the control panel 18 depends on the user. If the waist of the user is more obvious, the required degree of inflation of the waist airbag 16 is higher (that is, the inflation height is higher), if the waist of the user is less obvious (such as bucket waist), the waist airbag 16 The required degree of inflation is lower (that is, the inflation height is lower).

Step 104, after steps 101, 102, and 103, the memory of the control unit 11 will store a set of adjustment parameters, which are related to the pressure sensing results for determining the sleeping posture and control the inflatable motor group and the sleeping posture of the user. The electrical characteristics of the air valve group inflating or deflating the shoulder airbag 17 and the waist airbag 16.

When the user lies on the multi-layer bed 20 and sleeps, the control unit 11 will instantly monitor the pressure sensing result of the sleeping posture sensing unit 19, and determine the user based on the adjustment parameters of the pressure sensing result for determining the sleeping position The current sleeping position. The control unit 11 reads the electrical characteristics of the inflatable motor group and the air valve group in the memory according to the judged sleeping posture to control the inflator motor group and the air valve group to inflate or deflate the shoulder airbag 17 and the waist airbag 16 , And adjust the height and optimal hardness of the shoulder airbag 17 and the waist airbag 16 to match the user's shoulder or waist pressure to the optimal pressure in the judged sleeping position.
