Description

Battery support shell Technical Field The utility model relates to the technical field of battery manufacturing, in particular to a battery bracket shell. Background In the current energy storage and application fields, cylindrical lithium batteries are widely applied to various electronic devices, electric automobiles, energy storage systems and the like due to higher energy density, good charge and discharge performance and relatively stable chemical characteristics. In order to ensure the stability and safety of the cylindrical lithium battery during operation, as well as to achieve electrical connection and mechanical fixation between the batteries, battery supports become an indispensable important component. Currently, a common cylindrical lithium battery support usually adopts two independent components, which are respectively buckled at two ends of the battery. This design, although to some extent it allows for the support and fixation of the cells, and a plurality of such holders can be spliced into a plate-like structure for use in larger scale battery packs. However, the conventional battery support has the disadvantage that when the battery pack is in a vibrating environment, frequently carried or subjected to external force impact, the battery is easily subjected to loose displacement in the support because the supports at the two ends of the battery pack are independent of each other. This loosening in turn can create a pulling force on the conductive sheet welded to the end of the bracket. The conductive sheet is used as a key component for realizing the connection between the battery and an external circuit, and is extremely easy to break once being excessively pulled. The breaking of the conductive sheet not only can cause the interruption of the electrical connection between the battery and the circuit, so that the whole battery pack cannot work normally, the service performance of equipment is affected, and even potential safety hazards can be caused when the service performance of the equipment is serious. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provide the battery bracket shell which can prevent the conductive plates from being pulled and broken due to loosening of brackets at two ends of a battery so as to improve the service performance and the safety of equipment. The aim of the utility model is realized by the following technical scheme: A battery holder housing comprising: the shell comprises a top plate, a bottom plate and two side plates, wherein one end of each side plate is respectively connected with two opposite sides of the bottom plate in a sliding way, the end of each side plate far away from the bottom plate is respectively connected with two opposite sides of the top plate in a sliding way, and The locking pieces are respectively arranged at the four corners of the bottom plate and the top plate in a sliding mode, and are respectively abutted with the four corners of the side plates in a one-to-one correspondence mode, so that the locking pieces are clamped with the two side plates together.
