[0002] A battery pack is a device that combines multiple battery cells or battery modules into an integral unit, mainly used to store and provide electrical energy. A battery pack is usually composed of battery cells, a battery management system, a cooling system and a casing. The battery pack protective armor structure is a device used to protect the battery pack from external physical impact, chemical corrosion and other environmental factors. Most of the existing battery packs do not have a protective structure, which makes the battery pack easily damaged by external impact during use, and has low safety.

[0003] According to the description in a battery pack protection device for electric vehicles published on the patent website (authorization announcement number: CN211743264U), the battery pack protection device for electric vehicles includes "a third slider, a first slider, a second slider", etc. to protect the battery pack.
