Description

Technical Field

[0001] This utility model relates to the field of brackets, specifically to a plastic bracket for battery cells. Background Technology

[0002] With the development of outdoor energy storage, power tools, and electric vehicles, higher requirements are being placed on battery rate performance, energy density, and cycle life. For example, outdoor energy storage devices need to provide high power output in a short time to meet the startup and operation needs of electrical equipment; power tools also require batteries to discharge quickly to provide sufficient power when working under high loads.

[0003] Cylindrical batteries occupy an important position in the competitive landscape of batteries below 50Ah due to their high safety, flexible adaptability, high pack flexibility, and wide range of applications.

[0004] For existing battery cell brackets in the market, the battery pack is simply tightened by locking it with a common mold bracket or by making an adapter plate. Therefore, in actual application, there are limitations in the internal space of the battery pack and the impact of high-frequency vibration of the motor of a low-speed vehicle under actual working conditions. Therefore, based on the above reasons, a plastic battery pack bracket that can meet the actual use needs is designed. Utility Model Content

[0009] The pivot pin structure includes a plurality of first studs disposed on the upper support body and a plurality of second studs disposed on the lower support body.

[0010] The first stud can be nested and inserted into the corresponding second stud and locked by screws to achieve a stable connection between the upper support body and the lower support body.

[0011] As a preferred technical solution, the upper support body and the lower support body are respectively provided with a plurality of cell cavity positions, and each cell cavity position is used to embed the cell body.
