[0025] See also Figure 1-3 The utility model provides a technical solution: a folding bed with a pull-up structure. It includes a mounting plate 110, on which a pull-up assembly for folding and unfolding the folding bed is mounted, on which two sets of bed board assemblies for supporting the user are mounted, the two sets of bed board assemblies are symmetrically arranged with the mounting plate 110 as the center, and on which two sets of bed board assemblies are mounted two sets of support assemblies for supporting the bed board assemblies;

[0026] The pulling-up assembly includes two groups of connecting plates 210, which are respectively installed at both ends of the mounting plate 110, and a driving box 220 is installed on the side of one group of connecting plates 210 away from the mounting plate 110. A threaded rod 221 is rotatably connected in the driving box 220, and a moving block 223 is threadedly connected to the threaded rod 221. Two groups of racks 224 are installed on the side wall of the moving block 223, and the two groups of racks 224 are symmetrically arranged with the center line of the moving block 223 as the center. A motor 225 is installed at the bottom of the driving box 220, and the output end of the motor 225 passes through the driving box 220, and the output end of the motor 225 is transmission-connected to one end of the threaded rod 221.

[0027] When the folding bed is unfolded, the motor 225 drives the threaded rod 221 to rotate, so that the threaded rod 221 drives the moving block 223 to move vertically, and the moving block 223 drives the rack 224 to move vertically. Under the action of the rack 224 and the fan gear 227, the fan gear 227 is driven to rotate, so that the fan gear 227 drives the first rotating rod 226 to rotate, and the first rotating rod 226 drives the second bed board 330 to rotate. Under the hinged action of the second bed board 330 and the first bed board 320, the first bed board 320 is rotated, and the connecting plate 210 is driven to move at the same time, so that the first bed board 320 and the second bed board 330 are unfolded; when the folding bed is folded, the motor 225 drives the threaded rod 221 to reverse, so that the first bed board 320 and the second bed board 330 can be driven to fold, so that the folding bed can be stored, thereby eliminating the need for manual operation by the user.

[0028] Two groups of first rotating rods 226 are rotatably connected to the two groups of connecting plates 210, one end of the two groups of first rotating rods 226 are both inserted into the driving box 220, and the two groups of first rotating rods 226 are both installed with fan gears 227, which are respectively meshed with the two groups of racks 224. The racks 224 drive the fan gears 227 to rotate, so that the fan gears 227 can drive the second bed board 330 to rotate through the first rotating rods 226, so that the second bed board 330 is rotated to a horizontal position, thereby facilitating the unfolding of the folding bed.

[0029] Two sets of guide rods 222 are installed in the driving box 220. The two sets of guide rods 222 are symmetrically arranged around the threaded rod 221. Both sets of guide rods 222 are slidably connected to the moving block 223. The guide rods 222 are used to guide the moving block 223 so that the movement of the moving block 223 remains stable.

[0030] The bed board assembly includes a moving board 310, on which two groups of first connecting boards 311 are installed, and a second rotating rod 312 is rotatably connected between the two groups of first connecting boards 311. The bed board assembly also includes a first bed board 320 and a second bed board 330, one end of the first bed board 320 is fixedly installed on the second rotating rod 312, one end of the second bed board 330 is hinged to the other end of the first bed board 320, and the other end of the second bed board 330 is fixedly installed on the first rotating rod 226. Through the hinge connection between the first bed board 320 and the second bed board 330, the first bed board 320 is rotated at the same time during the rotation of the second bed board 330, and the moving board 310 is driven to move by the second rotating rod 312, thereby realizing the unfolding of the folding bed.

[0031] The support assembly includes two groups of support mechanisms, and the two groups of support mechanisms are symmetrically arranged around the center line of the moving plate 310. The support mechanism includes a first support rod 410, on which a first connecting rod 411 is installed, and a first hinge block 412 is installed at one end of the first connecting rod 411 away from the first support rod 410, and a first mounting block 413 is rotatably connected to the first hinge block 412, and the first mounting block 413 is installed on the moving plate 310, and the first mounting block 413 is located below the first connecting plate 311. The support mechanism also includes a second support rod 420, which is hinged on the first support rod 410. Extension rods 430 are installed on the first support rod 410 and the second support rod 420. A second connecting rod 421 is installed on the second support rod 420. A second hinge block 422 is installed on the end of the second connecting rod 421 away from the second support rod 420. A second mounting block 423 is rotatably connected to the second hinge block 422, and the second mounting block 423 is installed on the mounting plate 110. By moving the movable plate 310, the distance between the movable plate 310 and the mounting plate 110 is increased, so that the first connecting rod 411 and the second connecting rod 421 respectively drive the first support rod 410 and the second support rod 420 to move. At the same time, under the hinge action of the first support rod 410 and the second support rod 420, the first support rod 410 and the second support rod 420 are rotated and moved to the bottom edge of the first bed board 320 and the second bed board 330, and the first bed board 320 and the second bed board 330 are supported by the extension rod 430, thereby improving the stability of the folding bed.
