Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, and in particular to a hook-and-fix device which is convenient for assembly and disassembly. Background Art

[0002] Batteries are the core components of new energy electric vehicles. Traditional new energy electric vehicle battery packs usually put the battery pack into the battery pack, and then connect the battery pack to the bottom cover of the car by fastening bolts, and then fix the battery pack to the bottom of the car body by welding again. This makes the battery pack extremely inconvenient to disassemble and install. Therefore, detachable battery packs have received widespread attention. At present, detachable battery packs usually adopt a connection method of hooking and fixing with the bottom plate of the whole vehicle, so that the hooking device of the battery pack plays a more important role in the safety of the whole vehicle. How to design the installation structure of the detachable battery pack has received widespread attention. At present, the conventional detachable battery pack is installed and fixed to the bottom plate of the whole vehicle by the left and right side slides. If the hooking device of the left and right side slides is not strong enough, there is a risk of the battery pack falling from the whole vehicle. Therefore, how to strengthen the hooking and installation strength of the battery pack plays a great role in the application field of detachable battery packs. Utility Model Content
