Abstract
The invention discloses a box body of a battery, the battery and an electric device. The box body of the battery comprises a first beam, a second beam and a connecting assembly, and a groove is formed in the surface of the first beam; the second beam is arranged on one side, provided with the groove, of the first beam, and the first beam and the second beam are used for limiting a space for accommodating the battery monomers; and the connecting assembly is used for connecting the first beam and the second beam, and at least part of the connecting assembly is arranged in the first beam and the second beam. The battery comprises the box body of the battery. The power utilization device comprises the battery. According to the battery box provided by the invention, the connecting assembly is arranged in the first beam and the second beam to be connected with the first beam and the second beam, and the connecting assembly is matched with the first beam and the second beam to jointly share and bear relatively large external force, so that the structural strength of the battery box, the battery and the electric device is improved.
Description
technical field [0001] The present application belongs to the field of battery technology, and in particular relates to a battery box, a battery and an electrical device. Background technique [0002] Usually, the box structure of the battery includes several side beams and cross beams. Among them, every two side beams or between the side beams and the cross beams are welded and fixed, or connected by supports and connectors. The supports are usually connected by connectors. It is located at the outer peripheral surface of the end of the cross beam or the side beam, and is connected with the outer peripheral surface of the end of the other side beam or the outer peripheral surface of the middle region of the side beam through the connecting piece. [0003] During the actual production and use, it is found that the existing connection methods between the two side beams and between the side beams and the cross beams all have the problem of low connection strength, which needs ...
