Description

Technical Field

[0002] Lithium batteries are everywhere in our daily lives, and their demand is increasing rapidly, especially in the aerospace field and the field of new energy electric vehicles. Since the aerospace and electric vehicle fields have high requirements for the performance of lithium batteries, lithium batteries need to undergo a series of tests before leaving the factory, which includes vibration testing of lithium batteries. During the vibration test, the lithium battery module needs to be fixed on the vibration test equipment using a fixed fixture.

[0003] After searching, a Chinese patent with application number CN202020479250.9 discloses a fixed tooling for vibration testing of lithium battery modules, wherein the fixed bottom frame is welded by two groups of support rod groups, one group of support rod groups is arranged along the length direction of the battery module to be tested, and the other group of support rod groups is arranged along the width direction of the battery module to be tested; two adjustable angle irons are welded to the opposite surfaces of the two outer support rods of the support rod group arranged along the length direction of the battery module to be tested, and each adjustable angle iron has two ends provided with long through grooves extending along the length direction of the battery module to be tested; the two fixed brackets include a bottom rod arranged along the width direction of the battery module to be tested, and a vertical rod standing in the middle of the bottom frame, two installation and fixing holes matching the long through grooves are arranged at both ends of the bottom rod, and a support locking block is connected to the inner side of the vertical rod, and two fixing screw holes matching the fixed installation holes of the battery module to be tested are arranged on the support locking block.

During the battery vibration test, the battery module will produce longitudinal displacement, which not only affects the test results but also may damage the battery. For this reason, we propose a fixed tool for lithium battery module vibration testing to solve the above problems. Utility Model Content
