Description

Technical Field

[0001] The utility model relates to a housing body, in particular to a housing body for packaging a storage battery. Background Art

[0002] Storage batteries have a wide range of uses. With the popularization of new energy vehicles, the demand for storage batteries is also increasing. For small electric vehicles, when equipping the storage batteries on the electric vehicles, usually only the corresponding number of storage batteries are stuffed into the battery compartment according to the voltage requirements. However, for some high-end electric vehicles, the storage batteries often need to be integrally assembled, that is, the storage batteries need to be pre-installed in the housing body, and the electric energy stored in the storage batteries is led out to the outside through the outgoing wire connectors.

[0003] Chinese patent document (Publication No.: CN212934767U) discloses a plastic battery housing with a fast heat dissipation structure, including a housing main body. A heat dissipation plate is fixedly arranged at the center of the bottom of the inner wall of the housing main body. A plurality of batteries are arranged on both sides inside the housing main body. The tops on both sides of the housing main body are fixedly connected with the hooks fixedly arranged on both sides of the box cover through snap fasteners. The center of the top of the box cover is fixedly connected with the bottom of the slide rail. The plastic battery housing with a fast heat dissipation structure of the utility model can exchange heat with the outside during normal use and has a good heat dissipation effect. When the internal battery works for a long time, alcohol will be automatically wiped on the heat dissipation plate and dried with the cooperation of a blower. The alcohol can wipe off the dust on the surface of the heat dissipation plate, increasing the heat dissipation function. At the same time, the rapid evaporation of alcohol can take away a large amount of heat, and can complete the rapid heat dissipation of the internal battery, with a remarkable heat dissipation effect and high practicability.

[0004] This kind of battery housing is an integrally formed part, and it is not easy to take out the battery from the housing, thus making it inconvenient to replace and repair the battery. Content of the Utility Model
