[0025] Embodiment 1

[0026] Existing seat frames have a certain folding function to fold the seat cushion frame. However, when supporting the frame, the support structure is usually fixed only by bolts, resulting in a relatively low support stability for the seat cushion frame. This embodiment provides a foldable seat cushion frame assembly. By setting a reinforcement mechanism, after the seat cushion frame is deployed, the support structure can be more stably reinforced, improving the deployment stability of the seat cushion frame. Please refer to Figures 1 - 5 This foldable seat cushion frame assembly includes a seat cushion frame base 1 and a seat cushion frame back panel 2 rotatably connected to the end of the seat cushion frame base 1, so that the seat cushion frame base 1 and the seat cushion frame back panel 2 can be folded within a certain range, reducing the occupied space. A folding mechanism 3 is provided between the seat cushion frame base 1 and the seat cushion frame back panel 2, and a reinforcement mechanism 4 for enhancing its own connection is provided on the folding mechanism 3. Through the folding mechanism 3, the seat cushion frame back panel 2 and the seat cushion frame base 1 can be adjusted by 0-90°, and the two can be folded and deployed. Through the reinforcement mechanism 4, when the seat cushion frame back panel 2 is deployed, the structure with a support function can be reinforced, improving the stability when the seat cushion frame back panel 2 is deployed.

[0027] To improve the stability of the seat cushion frame when it is unfolded, the reinforcement mechanism 4 includes a reinforcement rod 401 movably connected to the folding mechanism 3. One end of the reinforcement rod 401 is fixedly installed with a resisting plate 402. The outer wall of the reinforcement rod 401 is threadedly connected with a resisting ring 403. By rotating the resisting ring 403, it moves along the outer wall of the reinforcement rod 401, so as to abut against the side of the insertion rod 312, strengthening one side of the insertion rod 312. A groove 404 is formed on the outer wall of the reinforcement rod 401 along its circumferential direction, facilitating the rotational storage of the resisting plate 405 inside the groove 404, so as to facilitate the insertion of the reinforcement rod 401 into the reinforcement hole 313. The resisting plate 405 adapted to the groove 404 is rotatably connected inside the groove 404, enabling one side of the resisting plate 405 to abut against the inside of the insertion rod 312, thus strengthening both the inside and outside of the insertion rod 312 and enhancing the support stability. A connecting spring 406 is fixed between the groove 404 and the resisting plate 405. Under the elastic action of the connecting spring 406, the resisting plate 405 has a certain ductility, thus enhancing the convenience of reinforcement.

[0028] By rotating the back plate 2 of the seat cushion frame, the connection angle between the base 1 of the seat cushion frame and the back plate 2 of the seat cushion frame can be adjusted, thus facilitating the folding of the two. The slider 308 slides inside the side square frame 305 along the outer wall of the slide rail 306. The connecting ends of the telescopic rod 311 and the insertion rod 312 are both rotatable at the connection with the slider 308. Through the cooperation with the slider 308, the telescopic rod 311 can be inserted into the insertion rod 312, thus supporting the back plate 2 of the seat cushion frame. When the position of the slider 308 is adjusted, the slider 308 is fixed by the fixing bolt 309, further enhancing the firmness of adjusting the telescopic rod 311 and the insertion rod 312. Press the resisting plate 405 to prevent the resisting plate 405 from popping out due to the elastic action of the connecting spring 406, so that the reinforcement rod 401 can be smoothly inserted into the reinforcement hole 313 to preliminarily fix the telescopic rod 311 and the insertion rod 312. Release the resisting plate 405 to make the resisting plate 405 unfold, and pull the reinforcement rod 401 to make one end of the resisting plate 405 abut against the inside of the insertion rod 312. By rotating the resisting ring 403, the resisting ring 403 abuts against the outside of the insertion rod 312, thus playing a role in reinforcement and further enhancing the stability of supporting the back plate 2 of the seat cushion frame.

[0029] Embodiment 2

[0030] On the basis of Embodiment 1, Figures 1 - 3 As shown, based on the fact that the existing seat frame has a certain folding function, the seat cushion frame is folded. However, when supporting the frame, the support structure is usually fixed only by bolts, which reduces the support stability of the seat cushion frame. But there is still a problem that the seat cushion frame cannot be quickly folded and is not convenient to carry and use. Therefore, the device is also provided with a structure having a folding function.

[0031] The folding mechanism 3 includes two sets of sliding components 31 respectively arranged on the seat cushion frame base 1 and the seat cushion frame backboard 2. A number of inner plates 301 and compression springs 302 are fixedly installed inside the seat cushion frame base 1 and the seat cushion frame backboard 2. The compression springs 302 are distributed directly above the inner plates 301. Through the mutual cooperation of the compression springs 302 and the inner plates 301, when the sponge board is sleeved, due to the elastic action of the compression springs 302, certain buffering performance is achieved during the installation of the sponge board. The inner plates 301 play a role in supporting the sponge board, enabling the device to have certain buffering and supporting performance during the installation of the sponge board. A positioning groove 303 is formed at the edge of the seat cushion frame base 1, and a positioning block 304 is fixedly installed at the edge of the seat cushion frame backboard 2. The positions of the positioning groove 303 and the positioning block 304 correspond to each other and are adapted to each other. Thus, when folding the seat cushion frame base 1 and the seat cushion frame backboard 2, they can be accurately and quickly combined, improving the folding efficiency. The sliding component 31 includes a side square frame 305. A slide rail 306 is fixedly installed on the inner wall of the side square frame 305. A slider 308 is slidably connected inside the slide rail 306. A fixing hole 307 is formed at the top of the side square frame 305. A fixing bolt 309 is connected to the top of the side square frame 305. The slider 308 is fixed to the side square frame 305 through the fixing bolt 309, thereby preliminarily fixing and supporting the adjusted seat cushion frame backboard 2. A telescopic rod 311 is rotatably connected to one set of the sliding components 31, enabling the telescopic rod 311 to be inserted into the insertion rod 312, improving the smoothness of folding. And the two are fixed through a reinforcement mechanism 4, so as to reinforce and support the insertion rod 312 and the telescopic rod 311. An insertion rod 312 used in cooperation with the telescopic rod 311 is rotatably connected to the other set of the sliding components 31. Reinforcement holes 313 are formed on the sides of both the telescopic rod 311 and the insertion rod 312.
