[0014] By adopting the above technical solution, the positioning block is first pulled toward the end away from the energy storage battery to deform the first spring, and then the adjusting block is moved. When the central axis of the nut coincides with the central axis of the first through hole, the positioning block is loosened, and the first spring restores its elastic deformation. Under the action of the elastic force of the first spring, the positioning block will be engaged with the slot on the adjusting block, and finally the fixing bolt is passed through the first through hole on the connecting block and threadedly connected to the nut.

[0018] By adopting the above technical solution, the slider is moved, and the slider drives the limiting block to move. When the limiting block does not interfere with the energy storage battery and the interference rod interferes with the energy storage battery, the slider continues to be moved. At this time, the interference rod will be displaced relative to the limiting block, and the interference rod drives the first rotating shaft to rotate through the first transmission assembly, and the first rotating shaft drives the display block to rotate. When the display block rotates a certain number of times, the limiting block will interfere with the energy storage battery at the end of the battery module, and finally the limiting bolt is passed through the slider and threadedly connected to the second stabilizing block; under the limitation of the two limiting mechanisms, the energy storage battery in the battery module can be confined in the accommodating cavity of the box body, thereby reducing the movement of the energy storage battery and improving the stability of the energy storage battery in the accommodating cavity of the battery module.

[0019] Optionally, a limiting mechanism is provided on the box body, and the limiting mechanism includes a limiting block, a buffer block, a third spring and an adjusting assembly.

The buffer block is slidably set in the first groove and can interfere with the energy storage battery; one end of the third spring is connected to the buffer block and the other end is connected to the side wall of the first groove.

[0020] By adopting the above technical solution, when the size of the energy storage battery changes, the limiting block is driven to move by the adjusting component, so that the limiting block drives the buffer block to move, and the buffer block will first contact the energy storage battery; then the limiting block is continued to move, so that the limiting block contacts the energy storage battery, reducing the movement of the energy storage battery, thereby improving the stability of the energy storage battery in the accommodating cavity; or when the energy storage battery is placed in the accommodating cavity, the energy storage battery will first contact the buffer block, squeezing the buffer block into the first groove of the limiting block, causing the third spring to deform, and finally the adjusting component is used to drive the limiting block to move, so that the limiting block can contact the energy storage battery.

[0022] By adopting the above technical solution, when the energy storage battery conflicts with the buffer block and the limiting block does not conflict with the energy storage battery, the limiting block continues to move, and the buffer block will be relatively displaced relative to the limiting block. At this time, the buffer block will drive the second rotating shaft to rotate through the second transmission assembly, and the second rotating shaft will drive the feedback display rod to rotate. According to the position of the feedback display rod, the position of the limiting block relative to the energy storage battery in the accommodating cavity is reflected, so that the limiting block can better limit the energy storage battery, and reduce the phenomenon that the limiting block continues to move when the limiting block conflicts with the energy storage battery, thereby reducing the phenomenon that the limiting block squeezes the energy storage battery.

The fourth transmission shaft 710 on the lifting block 79 drives the fifth gear 711 and the sixth gear 713 to descend, so that the fifth gear 711 engages with the fifth rack 712 on the buffer block 52, and the sixth gear 713 engages with the sixth rack 714 located on the limiting block 51.

[0061] When the limiting block 51 does not interfere with the energy storage battery 21 and the buffer block 52 interferes with the energy storage battery 21, the adjusting plate 544 continues to rotate. At this time, the buffer block 52 will move relative to the limiting block 51, and the fifth rack 712 on the buffer block 52 will drive the fifth gear 711 to rotate. The fifth gear 711 drives the fourth transmission shaft 710 to rotate. The sixth gear 713 on the fourth transmission shaft 710 drives the sixth rack 714 to move. The sixth rack 714 drives the seventh gear 715 to rotate. The seventh gear 715 drives the second rotating shaft 61 to rotate. The second rotating shaft 61 drives the feedback display rod 62 to rotate. When the limiting block 51 interferes with the energy storage battery 21, the second rotating shaft 61 will drive the feedback display rod 62 to rotate a certain number of times. That is, when the feedback display rod 62 rotates a certain number of times, it indicates that the limiting block 51 also interferes with the energy storage battery 21. Finally, the limiting bolt 545 is passed through the adjusting plate 544 and threadedly connected to the box body 1.

[0062] The operating principle of a universal mobile battery energy storage cabinet according to an embodiment of the present application is as follows: an operator holds the handles 356 on the connecting blocks 351 at both ends of an energy storage battery 21, then places the desired energy storage battery 21 into the housing 11 of the housing 1, and positions the connecting block 351 at one end of the energy storage battery 21 against the first stabilizing block 31. The operator then moves the second stabilizing block 32 toward one end of the energy storage battery 21, and positions the second stabilizing block 32 against the connecting block 351 at the other end of the energy storage battery 21. Stabilizing bolts 353 are then used to connect the first stabilizing block 31 to the connecting block 351 at one end of the energy storage battery 21, and the second stabilizing block 32 to the connecting block 351 at the other end of the energy storage battery 21. The operator then adjusts the position of two adjacent energy storage batteries 21 as needed, and positions the two ends of the connecting plate 371 against the connecting blocks 351 on the two adjacent energy storage batteries 21. Finally, the connecting bolts 372 pass through the connecting plate 371 and thread the connecting blocks 351. Finally, the entire battery module 2 is positioned within the housing 11 of the housing 1.

[0063] Then move the slider 41 so that the limit on the slider 41 contacts the energy storage battery 21 at the end of the battery module 2; then pass the sliding limit bolt 47 through the slider 41 and thread it into the second stabilizing block 32 to fix the slider 41 on the second stabilizing block 32; the two limiting mechanisms 4 at both ends of the battery module 2 will limit the battery module 2 to a position inside the box 1, reducing the movement of the energy storage battery 21 in the battery module 2.

[0064] Then the operator rotates the adjustment plate 544, and the adjustment shaft 541 on the adjustment plate 544 drives the second gear 542 to rotate, and the second gear 542 drives the second rack 543 to move, thereby realizing the movement of the limiting block 51; finally, when the limiting block 51 contacts the energy storage battery 21, the limiting bolt 545 passes through the adjustment plate 544 and is threadedly connected to the box body 1.

[0065] Under the constraints of the limiting block 51 , the limiting blocks 42 in the two limiting mechanisms 4 , the first stabilizing block 31 and the second stabilizing block 32 , the energy storage battery 21 with varying dimensions can be stably positioned in the accommodating cavity 11 .

[0066] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
