Description

A battery module fixing device

【Technical field】

The utility model relates to the technical field of batteries, in particular to a battery module fixing device.

【Background technique】

At present, electric vehicles have been more and more widely used due to their low-carbon environmental performance. Electric vehicles are usually equipped with multiple battery boxes, and each battery box contains a large number of single batteries connected in series and parallel to form a high-voltage battery module. After the battery module is put into the battery box, it needs to be pushed and fixed. The existing method is to put a push plate on the side of the battery module in the battery box, and set a fixing plate on the side of the push plate away from the battery module to fix the battery module. There are screw holes on the plate, and screws are screwed in with a wrench from the side of the screw holes away from the push plate, and the push plate is pushed by the screw so that the push plate is pressed against the battery module, so that the battery module is clamped between the push plate and the push plate. between the side walls of the battery box. However, in the existing method, on the one hand, because the screw is on the push plate, usually the screw is perpendicular to the push plate, when the wrench is turned, the wrench is likely to touch the side wall or the bottom wall of the battery box, so it is necessary to continuously loosen the wrench And adjust the angle with the screw, the operation is inconvenient and the efficiency is low; on the other hand, the screw is usually a thin cylindrical shape with low strength, and the weight of the battery module is about tens or hundreds of kilograms. Shaking occurs, and the screw directly supports the push plate with only a few thread teeth. Over time, the thread teeth may be worn or the screw may break directly, causing a safety hazard for the battery module.
