The first air chamber 101 or the second air chamber 102 can be inflated by the air pump 304, when the first air chamber 101 is inflated, the air inlet electric control valve 302 communicated with the first air chamber 101 is opened, and the air inlet electric control valve 302 communicated with the second air chamber 102 is closed, at this time, the first air chamber is inflated by the first air pipe 3 through the air pump 304, conversely, the air inlet electric control valve 302 communicated with the first air chamber 101 is closed and the air inlet electric control valve 302 communicated with the second air chamber 102 is opened, so that the second air chamber 102 can be inflated by the air pump 304.

[0027] Further, the first air chamber 101 and the second air chamber 102 are provided with discharge ports, and the discharge ports are fixedly installed with air outlet electric control valves 305. The gas in the first air chamber 101 and the second air chamber 102 can be discharged by opening the air outlet electric control valve 305 corresponding to the first air chamber 101 or the second air chamber 102, so that the soft cushion 2 can return to a flat state.

[0028] In the embodiment, a plurality of groups of connecting blocks are fixedly installed in the first air chamber 101 and the second air chamber 102, and the connecting blocks are arranged in a linear array in the first air chamber 101 and the second air chamber 102. A group of connecting blocks comprises a base 4 and a top seat 401 fixedly installed inside the first air chamber 101 and the second air chamber 102, the base 4 is located at the bottom of the first air chamber 101 and the second air chamber 102, and the top seat 401 is located at the top of the first air chamber 101 and the second air chamber 102.

[0029] It is worth noting that the cross section of the first air chamber 101 and the second air chamber 102 is a right triangle, and the base 4 and the top seat 401 are respectively located at two angles connected with the hypotenuse of the right triangle. When the first air chamber 101 and the second air chamber 102 are inflated, the top seat 401 will move upward, and the base 4 will remain stationary, and the rising height of the highest part of the first air chamber 101 and the second air chamber 102 can be judged by detecting the distance between the base 4 and the top seat 401, and the angle of the soft cushion 2 turned over by the first air chamber 101 and the second air chamber 102 can be judged.

[0030] The embodiment also includes an inclination detection assembly installed inside the first air chamber 101 and the second air chamber 102, which detects the angle of the soft cushion 2 turned over by the first air chamber 101 or the second air chamber 102 under different load-bearing conditions. The inclination detection assembly includes a displacement sensor 501 rotatably installed between a group of connecting blocks in the first air chamber 101 and the second air chamber 102, and a telescopic rod 5 rotatably installed between the remaining connecting blocks.

When the first air chamber 101 and the second air chamber 102 are inflated, the top seat 401 will be lifted, which will drive the displacement sensor 501 to rotate and stretch. Thus, the distance between the top seat 401 and the top seat 401 can be checked by the displacement sensor 501, and the angle of the soft cushion 2 turned over by the first air chamber 101 and the second air chamber 102 can be determined. The angle of the soft cushion 2 can be accurately determined when the first air chamber 101 and the second air chamber 102 bear different loads, which facilitates accurate adjustment of the inclination angle of the soft cushion 2, thereby effectively improving the comfort of the user.

Through the arrangement of multiple connecting rods 6, multiple top seats 401 can be lifted synchronously, and through the conduction of multiple connecting rods 6, the load borne by the first air chamber 101 and the second air chamber 102 can be evenly distributed on the surface of the entire first air chamber 101 or second air chamber 102, so that the surface of the first air chamber 101 and the second air chamber 102 is in a flat state, thereby effectively preventing the soft cushion 2 from being low in front and high in back, and ensuring the comfort of the user.

[0032] The embodiment also includes a control system that receives the detection signal of the inclination detection assembly and controls the inflation amount of the first air chamber 101 or the second air chamber 102 by the turning-over component. The control system controls the opening and closing state of the air pump 304 by receiving the data of the displacement sensor 501 inside the first air chamber 101 and the second air chamber 102, so that the displacement sensor 501 can be closed after reaching the specified scale. The first air chamber 101 and the second air chamber 102 can turn the soft cushion 2 to a specified angle when bearing different loads, and the opening and closing state of the air inlet electric control valve 302 and the air outlet electric control valve 305 can be controlled through a pre-set program, and the first air chamber 101 and the second air chamber 102 can be periodically exhausted and inflated by periodically driving the air pump 304, thereby achieving the effect of automatically and periodically turning over the user (the control system uses the existing technology, which is not described here).

[0033] The working principle of the embodiment is that the first air chamber 101 or the second air chamber 102 can be inflated by the air pump 304, the air inlet electric control valve 302 communicating with the first air chamber 101 is opened and the air inlet electric control valve 302 communicating with the second air chamber 102 is closed when the first air chamber 101 is inflated, at this time, the air pump 304 inflates the first air chamber through the first air pipe 3, conversely, the air inlet electric control valve 302 communicating with the first air chamber 101 is closed and the air inlet electric control valve 302 communicating with the second air chamber 102 is opened, so that the second air chamber 102 can be inflated by the air pump 304.

[0034] When the first air chamber 101 and the second air chamber 102 are inflated, the top seat 401 will be lifted, the lifted top seat 401 will drive the displacement sensor 501 to rotate and stretch the displacement sensor 501, so that the distance between the top seat 401 and the top seat 401 can be checked by the displacement sensor 501, and the angle at which the soft cushion 2 is turned over by the first air chamber 101 and the second air chamber 102 can be judged, so that the angle at which the soft cushion 2 is inclined can be accurately judged when the first air chamber 101 and the second air chamber 102 bear different loads, and the inclination angle of the soft cushion 2 can be accurately adjusted, thereby effectively improving the comfort of the user.

[0035] The control system controls the opening and closing state of the air pump 304 by receiving the data of the displacement sensor 501 in the first air chamber 101 and the second air chamber 102, so that the displacement sensor 501 can be closed after reaching the specified number, the first air chamber 101 and the second air chamber 102 can be turned over to the specified angle when bearing different loads, and the opening and closing state of the air inlet electric control valve 302 and the exhaust electric control valve 305 can be controlled by the preset program, and the first air chamber 101 and the second air chamber 102 can be periodically exhausted and inflated by the air pump 304, so as to realize the effect of automatically turning over the user periodically.
