Description

Technical Field

[0001] The utility model relates to the technical field of battery pack testing, in particular to a battery pack rollover and drop testing device. Background Art

[0002] Battery packs power electronic devices, and their quality significantly impacts their lifespan. When dropped, they can easily short-circuit and overheat, potentially damaging the device. Therefore, drop testing is crucial for battery packs. Scientific and rigorous drop testing can assess a battery pack's resistance to impact and safety under varying drop conditions.

[0003] A battery pack flip and drop test device disclosed in Chinese patent CN220854101U is retrieved. The trigger mechanism is set to trigger the bracket unit to flip and fall relative to the base, so that the bracket unit contacts the ground, thereby truly simulating the actual force conditions of the battery when the bracket system flips and falls, effectively controlling the occurrence of the bracket unit flipping and falling, and fully ensuring the personal safety of the experimenters.

[0004] However, a battery pack drop test device has some shortcomings. This device, which flips and drops the battery by placing it on top of a bracket, can only meet one testing requirement. In actual testing, different battery packs may require different testing conditions and methods. Due to its structural limitations, this device cannot flexibly adjust and adapt to different testing requirements. Furthermore, the high top of the bracket requires operators to spend more energy and time when placing the battery pack, increasing the complexity and labor intensity of the work. Currently, no effective solution has been proposed to address these issues in the related art. Utility Model Content
