Problems solved by technology
[0002] With the development of technology, new energy vehicles have attracted increasing attention from the society in today's era of advocating "low-carbon energy conservation and environmental protection". The key research direction of technicians, the power battery generally cooperates with the battery tray and the protective cover, and the battery tray and the protective cover are connected to package the power battery. In terms of the connection method of the battery tray and the protective cover, some Drill holes with the protective cover, and then connect the two with bolts, and some use adhesives to connect between the battery tray and the protective cover, and then with the development of new energy vehicles, the existing battery tray and protective cover The connection scheme is no longer applicable, so the structure of the battery pack needs to be improved

The invention provides a protective cover for a tray and a battery pack. The protective cover includes a cover body and a bottom plate for connecting the tray; the cover body and the bottom plate aremutually connected; at least part of the circumference of the bottom plate comprises a thin layer area located outside and a connecting area located inside; and a plurality of weak layers are stackedand are mutually connected to form the thin layer area. The plurality of mutually-connected weak layers can be separated to realize multiple times of use of the protective cover. When the protective cover and the tray need to be disassembled to repair he battery pack, the lowest weak layer and the second lowest weak layer are separated, damage separation of the protective cover on the tray can beavoided, the protective cover can be used for multiple times on the tray, and the repair cost is saved.
