The third driving mechanism 2423 drives the movable pulley group 2422 to slide. When the third driving mechanism 2423 drives the movable pulley group 2422 to slide, the movable pulley group 2422 approaches / moves away from the first fixed end 2411 of the load-bearing rope group 241, thereby lifting / lowering the sling 25. When only a single movable pulley group 2422 is set, the load-bearing rope group 241 and the passive pulley group 2422 are divided into two sections. According to the working principle of the movable pulley, the maximum stroke of the sling 25 can reach twice the moving distance of the movable pulley group 2422.

[0030] Preferably, the configuration direction of the load-bearing rope group 241 is set according to the preset placement mode of the battery box 40 in actual conditions. In this embodiment, the battery box 40 is arranged along the first direction X, the load-bearing rope group 241 is arranged along the first direction X, the movable pulley group 2422 is slidably connected to the third frame 2421 along the first direction X, and the third driving mechanism 2423 drives the movable pulley group 2422 to slide along the first direction X, and when the movable pulley group 2422 slides along the first direction X, the sling 25 is lifted / lowered.

[0031] More preferably, the fixed pulley group 243 has at least two fixed pulleys, and the fixed pulleys are at least disposed at two opposite ends of the third frame 2421 .

[0032] Specifically, in this embodiment, the number of the fixed pulleys is three pairs, and the fixed pulley group 243 includes a first fixed pulley 2431, a second fixed pulley 2432 and a third fixed pulley 2433. The first fixed pulley 2431 is fixed to the second frame 22, and the second fixed pulley 2432 and the third fixed pulley 2433 are respectively fixed to the two ends of the third frame 2421 along the first direction X.

[0033] Preferably, the movable pulley group 2422 has at least one movable pulley, and the number of the third slide rails 2424 and the slide seats 2425 is adapted to the number of the movable pulleys. Accordingly, the third driving mechanism 2423 is a combination of one or more of chain drive, belt drive, gear drive, and screw drive.

[0034] Specifically, in this embodiment, the number of the movable pulley groups 2422 is two, and the two movable pulleys are arranged in pairs. The third driving mechanism 2423 includes a motor 24211 fixed to the third frame 2421, a screw rod 24212 connected to the motor 24211, and a slider 24213 matched with the screw rod 24212. The two movable pulleys are relatively arranged on both sides of the slider 24213 and are respectively fixed to the sliding seat 2425.

[0035] In this embodiment, the third driving mechanism 2423 drives the screw rod 24212 to rotate through chain transmission, so that the slider 24213 and a pair of movable pulleys fixed to the slider 24213 slide along the first direction X, so as to approach or move away from the first fixed end 2411 of the load-bearing rope group 241. When the motor 24211 of the third driving mechanism 2423 rotates forward, the slider 24213 drives the movable pulley away from the first fixed end 2411 of the load-bearing rope group 241, which plays a role in lowering the weight. When the motor 24211 of the third driving mechanism 2423 rotates reversely, the slider 24213 drives the movable pulley close to the first fixed end 2411 of the load-bearing rope group 241, which plays a role in lifting the weight, wherein the stroke of the suspension point of the load-bearing rope group 241 is twice the stroke of the movable pulley group 2422.

[0036] It is understandable that when the movable pulley group 2422 is set to multiple groups, the stroke of the suspension point of the load-bearing rope group 241 can also be further increased, so that the maximum stroke of the sling can reach multiple times the moving distance of a single movable pulley group.

[0037] By this means, the present invention arranges a movable pulley group 2422 that slides in the direction of approaching / moving away from the fixed end of the load-bearing rope, so that the maximum stroke of the sling can reach twice the moving distance of the movable pulley group, thereby ensuring that the load is lifted in a limited space while increasing the lifting distance of the lifting device 24. The structure is simple and compact, the installation is convenient, the operation is stable, the cost is low, and it is easy to modularize and assemble.

[0038] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
