Description

Technical Field

[0002] Specifically, the present invention proposes a rotary-controlled battery convenient disassembly and assembly device, which adopts innovative designs such as a rotary-controlled drive mechanism, an elastic power connection mechanism and a quick-release top cover, and can realize the synchronous and rapid disassembly and assembly of battery modules, connecting lines and charging connectors, thereby greatly improving the efficiency of battery replacement.

Background Art

[0004] With the rapid development of two-wheeled electric vehicle technology, battery technology is also constantly upgrading. Key indicators such as energy density, cycle life and safety of electric vehicle batteries continue to improve, thereby extending the range of electric vehicles, reducing usage costs and increasing value. As the "power source" of electric vehicles, the performance of electric vehicle batteries is crucial to improving user satisfaction. However, the disassembly, assembly and maintenance process of existing electric vehicle batteries is inconvenient.

[0005] Authorization announcement number CN203536486U discloses a storage battery that facilitates circuit docking, including a housing, multiple single cells, and a tongue for fixing. Although the design achieves quick circuit connection through the sliding fit of the socket pins, and the rain shield can also prevent rain from entering when the battery is removed, the overall disassembly and assembly process of the battery is still complicated and cumbersome.

[0065] It should be noted that the wires are arranged inside the explosion-proof top cover 3 and are connected in series.

[0066] It should also be noted that, in order to facilitate heat dissipation of the battery module 2, a heat dissipation channel (not shown in the figure) is opened on the surface of the explosion-proof frame 1, and the cross-section of the heat dissipation channel (not shown in the figure) is Z-shaped.

Compared with the traditional bolt fixing method, the overall operation is simple, without the need for tedious bolt tightening operations, which facilitates the disassembly and assembly of the battery module 2, effectively improves work efficiency, and ensures that the fixing force is uniform and stable.
