[0023] The bottom of the box body 1 is provided with a cushion block, and the cushion blocks have gaps therebetween, so as to facilitate the loading and unloading and transportation by a forklift.

[0024] The claw 24 has three states, ① storage state: the claw 24 is stored in the accommodating cavity 23; ② battery box installation state: the claw 24 is turned out at a certain angle, and the opening direction of the claw 24 is parallel to the longitudinal direction of the limiting slot 22; and ③ battery box installation state: the bottom of the claw 24 abuts against the bottom of the accommodating cavity 23 to reach the maximum turning-out angle.

[0025] The torsion box 25 is a structure of torsion spring plus limiting.

[0026] When the device is in use, the battery box 3 with the battery is hung into the box body 1 through the lifting ring 31. When the first layer of battery box 3 is installed from bottom to top, the buffer device 32 of the battery box 3 enters the claw 24, the claw 24 is turned out to the maximum angle of turning out under the weight of the buffer device 32, the battery box 3 and the battery, overcoming the torsion force of the torsion spring in the torsion box 25, and at the same time, the non-proportional transmission mechanism between the first layer and the second layer of the claw 24 drives the second layer of the claw 24 to turn out to the state of installing the battery box, and in the non-proportional transmission mechanism between the second layer and the third layer of the claw 24, the driving wheel 61 drives the driven ring 63 to rotate through the transmission chain 64, and the inside of the driven ring 63 pushes the block 630 to slide in the gap 620 of the driven wheel 62 to the side wall of the gap 620. When the second layer of battery box is installed, the second layer of the claw 24 is turned out to the maximum angle of turning out under the weight of the buffer device 32, the battery box 3 and the battery, overcoming the torsion force of the torsion spring in the torsion box 25, and at the same time, the non-proportional transmission mechanism between the second layer and the third layer of the claw 24 drives the third layer of the claw 24 to turn out to the state of installing the battery box, and in the non-proportional transmission mechanism between the third layer and the fourth layer of the claw 24, the driving wheel 61 drives the driven ring 63 to rotate through the transmission chain 64, and the inside of the driven ring 63 pushes the block 630 to slide in the gap 620 of the driven wheel 62 to the side wall of the gap 620. In the turning of the second layer of the claw 24 in the installation of the battery box 3, the block 630 and the gap 620 between the driven ring 63 and the driven wheel 62 are designed to allow the second layer of the shaft to rotate within a certain range relative to the first layer of the shaft, and the second layer of the shaft will not be further driven by the non-proportional transmission mechanism to rotate while rotating. By analogy, when the Nth layer of the claw 24 is installed with the battery box 3, the N+1th layer of the claw is in the state of installing the battery, so that the battery box 3 and the battery can be installed layer by layer. When all the battery boxes 3 are installed, the locking block 214 is rotated into the limiting groove 22 by rotating the handle 212, and the position of the claw 24 is locked. The buffer device 32 installed in the claw 24 is longitudinally locked under the limiting action of the claw 24 and the limiting edge 220. When the battery needs to be taken out, the claw 24 will be automatically stored under the torsion force of the torsion box 25, so that the battery can be easily taken out and fixed in the box body 1.

[0027] The buffering principle of the device is that a plurality of claws 24 of different heights lock the longitudinal positions of the battery boxes 3 of different layers at predetermined heights of the support frame 21 in sequence and at equal intervals. When the box 1 is subjected to a longitudinal impact force, the support frame 21 as a whole absorbs the longitudinal impact force through the hydraulic damping device 20, effectively reducing the longitudinal impact on the batteries. When the batteries encounter an accident during transportation and are subjected to a violent lateral impact, all the buffering devices 32 on the side subjected to the impact provide a buffering thrust, and all the buffering devices 32 on the opposite side provide a buffering pull, greatly absorbing the impact energy. When the buffering devices 32 on the side subjected to the impact approach the compression limit, the side of the battery box 3 will be compressed onto the buffering air bag 11 on the side subjected to the impact as a whole, further absorbing the impact energy, thereby effectively avoiding the phenomenon of thermal runaway of the batteries due to severe impact.
