Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a shell structure of an electric energy storage battery. Background Art

[0002] The contemporary automobile industry is undergoing revolutionary changes, that is, traditional fuel vehicles are gradually being replaced by new energy vehicles. Among them, pure electric vehicles as a type of new energy vehicles have gained a lot of favor, and energy storage batteries as the main components of electric vehicles have received more and more research.

[0003] In layman's terms, an energy storage battery is equivalent to installing multiple small batteries in the battery pack shell and connecting them in series or parallel. Usually, multiple small batteries are fixed by manual welding one by one, which has poor construction efficiency and high-temperature welding operations can easily damage the small batteries, which is very dangerous.

[0006] The technical solution of the utility model uses a frame-like component as a shell of a small battery. During installation, the frame-like component can be plugged into the battery pack shell through a connector at the bottom and locked with glue or screws. At the same time, two frame-like components adjacent to each other front to back or left to right can be connected by inserting a pin into a strip hole. Therefore, during construction, multiple small batteries can be carried at one time and placed on the battery pack shell, and then the small batteries can be fixed one by one, which effectively improves the construction efficiency. Of course, the small batteries can also be fixed by plugging them into the corresponding structure on the battery pack shell through the strip hole. The overall structure is simple and the safety of cold operation construction is relatively high. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solution of the utility model uses a frame-like component as a shell of a small battery. During installation, the frame-like component can be plugged into the battery pack shell through a connector at the bottom and locked with glue or screws. At the same time, two frame-like components adjacent to each other front to back or left to right can be connected by inserting a pin into a strip hole. Therefore, during construction, multiple small batteries can be carried at one time and placed on the battery pack shell, and then the small batteries can be fixed one by one, which effectively improves the construction efficiency. Of course, the small batteries can also be fixed by plugging them into the corresponding structure on the battery pack shell through the strip hole.

[0017] Specifically, the connector 3 is provided with a plurality of through holes 33. After the frame-shaped member 1 is installed in the module housing, the frame-shaped member 1 can be further fixed by inserting a latch through the module housing and the through holes 33 in sequence.

[0018] Specifically, the second accommodation space is flat, and the top and bottom walls of the second accommodation space are formed with a long strip-shaped connecting portion 4, and one side of the connecting portion 4 is provided with a strip-shaped groove 41 along the length direction of the connecting portion 4, and the two strip-shaped grooves 41 are vertically spaced and aligned. When the second accommodation space accommodates a circuit board, the circuit board can be plugged into the second accommodation space by inserting the two side edges of the circuit board into the two strip-shaped grooves 41 respectively.
