Abstract

The invention relates to the field of new energy vehicles, and provides a battery box body, a battery pack and a vehicle. The battery box body comprises a lower box body and a structural reinforcing part, the structural reinforcing part comprises a first beam body and a second beam body, the first beam body and the second beam body are arranged in a crossed mode, the first beam body is connected with the lower box body and provided with a turned-over edge, the turned-over edge is connected with the lower box body, and / or the second beam body is connected with the lower box body, the second beam body is provided with a turned-over edge, and the turned-over edge is connected with the lower box body. According to the battery box body, the contact area between the structural reinforcing part and the lower box body can be increased through the arrangement of the turned-over edge, so that the connection strength between the structural reinforcing part and the lower box body is improved.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a battery box, a battery pack and a vehicle. Background technique [0002] At present, a battery pack is installed in a new energy vehicle. The battery pack includes a battery box and a battery module. The battery box includes an upper box and a lower box. A reinforcing beam is installed between the upper box and the lower box. Part of the reinforcing beam plays the role of increasing the connection strength between the upper box and the lower box, and on the other hand, it plays the role of separating the internal space of the battery box, so as to divide the inside of the battery box into multiple accommodating cavities. The module is installed in the accommodating chamber. [0003] In the prior art, the reinforcing beam is directly connected to the lower box body, and the connection strength is relatively weak. Contents of the invention [0004] The...
