[0028] Specific implementation mode two: as figure 1 As shown, this embodiment is a further description of Embodiment 1. The folding mechanism includes two folding parts arranged side by side at the left and right ends of the support base 15, and each of the folding parts includes a travel limit switch 10, Linear motor 11, connecting plate 13, spine structure shell 29 and X-type folding frame 30; Described linear motor 11 is horizontally fixed on the front end of support base plate 15, and the outer end of linear motor 11 is provided with protective plate 67, and linear motor 11 The upper end is provided with a limit support mechanism 16, and the movable end of the linear motor 11 is set in cooperation with the stroke limit switch 10 through the linear motor connector 18, and the linear motor connector 18 is provided with a stroke limit switch 10 when it reaches the predetermined stroke position during the movement. The linear motor 11 is connected with one end of the lower end of the X-type folding frame 30 arranged vertically, the other end of the lower end of the X-type folding frame 30 is connected with the support base plate 15 by the X-type folding frame hinge 64, and one end of the X-type folding frame 30 upper end It is slidingly connected with the slide rail 27 through the slider 19, and the slider 19 is fixedly connected with the ratchet structure shell 29 through the connecting plate 13, and the other end of the upper end of the X-shaped folding frame 30 is connected with the slide rail 27 through the X-shaped folding frame hinge 64 .

[0029] Specific implementation mode three: as image 3 , 4 , 5, and 6, this embodiment is a further description of the second specific embodiment. The backrest drive system mechanism 2010 includes an intermediate support 39, a gear 211, a rack 219, an upper ratchet bar 236, a lower ratchet bar 256, Hinge four-bar mechanism 68, fixed guide 204, support frame 238, return pin 240, lower spine 256 and rotating shaft 291; The inside of described spine structure shell 29 is fixedly connected with support frame 238 by set screw 258, so The support frame 238 is provided with a horizontally arranged lower ratchet bar 256 that can move up and down (the positioning holes at the lower end of the support frame 238 are equipped with a plurality of fixed mandrels 201, and the outer sides of the plurality of fixed mandrels 201 are The spring 206 is sleeved and the upper end is fixedly connected with the lower ratchet bar 256, and the two ends of each spring 206 respectively lean against the lower ratchet bar 256 and the support frame 238, so that the lower ratchet bar 256 can move up and down in the support frame 238) , the lower spine 256 is meshed with the upper spine 236, and connected through the fixed guide 204, the upper spine 236 is connected with the support frame 238 through a sliding groove, and the upper spine 236 is connected by a plurality of hexagon socket screws 257 is fixedly connected with the rack 219, and the rack 219 is meshed with the vertically arranged gear 211. The gear 211 is fixedly set on the outside of one end of the rotating shaft 291 through the key 179, and the end surface is fixedly connected with the hinge four-bar mechanism 68. The other end of the rotating shaft 291 is rotationally connected with the intermediate support 39 through a bearing one 292, and the outer side of the bearing one 292 is compressed by a bearing stop ring 290, and a bearing through cover 294 is also provided; the intermediate support 39 is fixed on the slide The upper end of the rail 27 and the outside of the support frame 238 are elastically connected to the return pin 240 through the return spring 244. The return pin 240 is connected to the upper ratchet bar 236, and a sleeve 293 is also provided between the rotating shaft 291 and the gear 211. The sleeve 293 is compressed by the shaft end retaining ring 175 and the screw 176 .
