Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, in particular to a battery pack with an anti-seismic structure. Background Art

[0002] Existing rechargeable power sources, such as power batteries for electric bicycles, generally use multiple cells connected in parallel and in series to expand the battery capacity and increase the battery voltage. Some of the multiple cells are directly placed in the battery outer box. Due to the lack of necessary fixation of the cells, this installation method makes the electrical contact of the cells unreliable, and external vibrations can easily affect the state of the cells. The working stability of the entire battery in a high-vibration environment is very poor. Some also fix the multiple cells tightly together. Although this method solves the problem of battery shock resistance to a certain extent, the multiple cells are squeezed together, which is not conducive to heat dissipation during operation and also affects the working stability of the battery.

[0003] In the existing technology, when a battery pack is installed and applied to electrical equipment or vehicles, a shock-absorbing material is placed on the bottom or peripheral side of the battery pack. This will affect the use and installation of the electronic pack in case of emergency stress damage, resulting in a relatively simple and poor earthquake resistance. In response to this, the present invention provides a battery pack with an earthquake-resistant structure. Utility Model Content
