Technical Field

[0001] The utility model provides a multi-angle detection tool for a lower shell of a battery pack, and relates to the field of battery pack detection tools. Background Art

[0002] The battery pack is a shell wrapped around the outside of the battery pack, which usually plays the role of fixing the battery pack or battery cell, and also protects the battery pack or battery cell inside. It is an important component of the battery pack and battery cell. After the automobile battery pack is manufactured, the strength of the automobile battery pack shell needs to be tested, because during the use of the vehicle, if the car is hit hard, the battery pack will be deformed by the impact, and in severe cases, it will directly cause the batteries in the battery pack to explode, which poses a safety hazard to personnel.

[0003] After searching, the Chinese patent with publication number CN221350475U discloses a new energy vehicle battery pack detection device. During the simulated impact detection process, the battery pack can be tested for strength impact at different angles, without the need to conduct impact simulation tests on nearly completed vehicles, thus reducing the test cost and safety hazards. However, the battery pack is installed in the vehicle, and the most common abuse conditions usually occur at the bottom of the vehicle, such as scratches, bottoming, ball strikes, punctures, etc. on the bottom, which have a serious impact on the lower shell of the battery pack, and the above-mentioned battery pack detection device can only simulate frontal impacts, and cannot simulate a series of situations for the lower shell of the battery pack. To this end, we propose a multi-angle detection tool for the lower shell of the battery pack. Utility Model Content
