A support plate 8 is arranged on the adjacent side of the two fixed support plates 1, and a lifting mechanism 2 is arranged on the front side of the fixed support plate 1. The lifting mechanism 2 is used to adjust the height of the support plate 8;

[0033] Specifically, a plurality of arc surface blocks 5 are arranged in sequence along the length direction of the mattress body in the mattress body, and there is a gap between adjacent two arc surface blocks 5. Therefore, a relatively large angle can be bent between each adjacent two arc surface blocks 5. Furthermore, the whole formed by the plurality of arc surface blocks 5 is easy to bend, which is more conducive to matching with an electric bed, and has a variety of bending methods, so as to better fit the bending radian of the electric bed.

[0034] Refer to Figure 2 、 Figure 4 and Figure 5, the lifting mechanism 2 includes an anti-slip round block 205. The anti-slip round block 205 is fixedly connected to the front part of the front fixed support plate 1. A rotating round block 206 is arranged on the front side of the anti-slip round block 205. Threaded round blocks 202 are rotatably connected to the adjacent sides of the two fixed support plates 1. A cylinder 201 is fixedly connected to the adjacent sides of the two threaded round blocks 202. A universal joint 204 is fixedly connected to the adjacent sides of the two cylinders 201. Support bars 203 are fixedly connected to the front and rear sides of the bottom of the support plate 8. The front cylinder 201 passes through the front fixed support plate 1 and is fixedly connected to the rotating round block 206;

[0035] Specifically, by rotating the rotating round block 206 clockwise, as the rotating round block 206 rotates, it can drive the cylinder 201 to rotate, and drive the threaded round block 202, so that the support bar 203 moves up and down under the rotation of the threaded round block 202, thereby driving the up and down movement of the support plate 8. And through the universal joint 204, the threaded round blocks 202 on both sides rotate together, and the rotation round block 206 is engaged with the anti-slip round block 205, making it impossible to rotate counterclockwise.

[0036] Refer to Figure 1 、 Figure 3 and Figure 5 , an L-shaped baffle 9 is fixedly connected to the top of the arc-shaped block 5. Activated carbons 19 are fixedly connected to the front and rear sides of the bottom of the support plate 8. A negative ion generator 10 is fixedly arranged on the rear side of the top of the support plate 8. Fixed blocks 11 are fixedly connected to the left and right sides of the negative ion generator 10. The fixed blocks 11 are fixedly connected to the support plate 8. A plurality of ventilation holes 13 are opened on the top of the support plate 8. A plurality of concave grooves 12 are opened on the upper and lower sides of the support plate 8. Fixed columns 14 are fixedly connected to the left and right sides of the two fixed support plates 1.

A micro generator 18 is fixedly connected to the bottom of the support plate 8. The output end of the micro generator 18 penetrates through the trachea 17. A smoke alarm 20 is fixedly connected to the bottom of the front support bar 203. A plurality of anti-slip grooves 21 are opened on the outer side of the rotating round block 206;

[0039] Specifically, when a person lies on the mattress, the airbag 16 is pressed to allow the air inside to flow out through the air pipe 17, thereby driving the micro generator 18 to generate electricity. The smoke alarm 20 can detect the generation of fire in time, and the anti-skid groove 21 can improve the anti-skid ability of the rotating round block 206.

[0040] Working principle: Before using the device, first, the keel of the entire mattress is arranged one by one along the length direction of the mattress body through multiple arc blocks 5, and a certain gap is left between each arc block 5. This allows a larger bending angle to be achieved between each two adjacent arc blocks 5, thereby enhancing the flexibility of the entire arc block 5 assembly and making it easier to bend. It improves the compatibility with electric beds, because electric beds often require mattresses to adapt to their bending arcs during use. In addition, due to the diverse combination of multiple arc blocks 5, the mattress can present a variety of bending forms, further ensuring the fit with the bending arc of the electric bed, and through the lifting mechanism 2, by rotating the round block 206 clockwise, the cylinder 201 can be driven to rotate synchronously. During the rotation of the cylinder 201, the rotation of the threaded round block 202 is driven. It will directly act on the support bar 203, and under the rotation of the threaded round block 202, the support bar 203 will realize the function of moving up and down. The up and down movement of the support bar 203 drives the up and down movement of the support plate 8 to achieve the required position adjustment. In addition, through the linkage of the universal joint 204, the threaded round blocks 202 on both sides can rotate synchronously to maintain the coordination and consistency of the overall structure. At the same time, the rotating round block 206 and the anti-slip round block 205 are designed to prevent the rotating round block 206 from rotating counterclockwise, ensuring the stability and safety of the operation.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
