[0002] Most electric vehicles on the market have their power batteries installed under the floor, which basically covers the entire floor. When a collision occurs, the battery pack is very susceptible to impact and compression. The battery pack is placed under the floor, and there is more or less protection around it, but the bottom lacks protection, which is the weakest link of the battery pack. During the battery production process, the bottom of the battery needs to be subjected to a ball impact test.

[0003] The publication number CN219715103U retrieved after searching disclosed a test bench suitable for a ball impact test on the bottom of a new energy power battery. The test bench controls the position of the battery pack by setting a slide rail and a first translation drive mechanism, and aligns the steel ball with the ball impact position by moving the second translation drive mechanism. The ball impact test at different positions on the bottom of the battery pack can be completed without removing the support frame.

[0004] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art that have not been solved: in the above case, during the battery testing process, the battery needs to be fixed and then the ball impact test is carried out. After the battery test, the staff needs to disassemble the battery and then fix the next group of batteries to be tested before continuing the ball impact test. During the battery installation and replacement process, a lot of time is consumed, which affects the efficiency of the battery ball impact test.

[0005] Therefore, we propose a battery bottom ball impact test bench, which will not affect the battery bottom ball impact test during the battery installation and removal process. Utility Model Content
