Description

Technical Field

[0001] This utility model relates to the technology of mattresses, and in particular to an intelligent adjustable airbag mattress based on precise distance measurement. Background Technology

[0002] With people's increasing demands for sleep quality and the precise needs of the medical and nursing field for mattress support, air-cushion adjustable mattresses, due to their flexible adjustability, are gradually becoming an important development direction for civilian sleep products and medical and nursing products.

[0003] In the prior art, a mattress is disclosed that includes a main control module, an inflation / deflation system, and multiple parallel, elongated airbags. Each airbag contains a pressure sensor connected to the main control module. The main control module inflates and deflates each airbag via the inflation / deflation system. When the patient lies on the mattress, the system automatically detects the pressure on different parts of the body. If excessive pressure is detected on a particular part of the body for an extended period, the system automatically adjusts the pressure by inflating or deflating the airbags. However, this structure relies solely on the pressure sensors to collect the air pressure within the airbags, indirectly inferring the body's support needs. This method only reflects the pressure state within the airbags and cannot directly correlate with the actual sinking displacement of different body parts. For example, under the same air pressure, lighter users experience less sinking displacement, while heavier users experience more. Adjusting solely based on air pressure results in different support levels for the same air pressure, failing to match individual differences and exhibiting low accuracy.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content

Several precise distance measurement devices are set for the top layer of each airbag, so that the distribution of the precise distance measurement devices can cover the area of ​​the top layer that needs to be detected. Thus, the precise distance measurement devices can obtain the precise lifting and lowering displacement distance of each part of the top layer, thereby obtaining the user's precise body curve. Combined with an air pressure detection device to detect the air pressure of the airbag, the two work together to achieve precise adjustment of the user's body curve.

Therefore, they should not be construed as limitations on this utility model.

[0023] The airbag 20 includes a top layer 21, a bottom layer 22, and an annular bladder 23 connecting the top layer 21 and the bottom layer 22. The top surface of the top layer 21 is flush with the top surface of the annular pad 12. A middle connecting layer 24 is provided inside the annular bladder 23. The middle connecting layer 24 can prevent the annular bladder 23 from deforming too much when it is compressed, so that the lifting and lowering of the top layer 21 is more stable. In this embodiment, the airbag 20 is elongated, the annular bladder 23 is annular racetrack shaped, the top layer 21 and the bottom layer 22 are both square and extend outward beyond the annular bladder 23. The portion extending outward beyond the annular bladder 23 forms an edge 211. The setting of the edge 211 makes the adjacent airbags 20 fit more tightly and will not have large gaps that would affect the user experience.

[0024] The control system is electrically connected to an air pressure detection device 40 for detecting the air pressure inside the airbag 20 and a precision distance measuring device 50 for detecting the lifting displacement of the top layer 21. The precision distance measuring device 50 is provided for each airbag 20 and is arranged along the length direction of its top layer 21.

The control system can store standard body curve data of normal people. The control system compares the user's body curve with the standard body curve to obtain the difference. By adjusting the air pressure, the control system can accurately adjust the user's body curve. At the same time, during sleep, the control system can obtain the sleeping posture and approximate weight of the human body and adjust the air pressure in real time to make the sleeping posture, especially the spinal shape, closer to the standard body curve. When used with a pillow, the pillow height can also be adjusted according to the sleeping posture to make the human body achieve the best sleeping position.

In this embodiment, the air pressure detection device 40 is disposed on the first PCB board 60. The air pressure detection device 40 is an air pressure sensor. The air pressure detection device 40 is disposed in the annular bladder 23 so as to reflect the air pressure in the airbag 20 more quickly and accurately.
