Many core components are installed in a box inside the battery pack, so there are very high requirements for the lower shell (battery box). At present, stir friction welding and CMT welding are used to achieve welding of relevant parts of the battery box. The battery box has high requirements for airtightness testing. The inner cavity of the product is required to be completely sealed. If cracks or side leakage occur, it will seriously affect the service life of the product and cause safety hazards. Therefore, it is necessary to design a device that can accurately detect airtightness according to the airtightness requirements put forward by customers to ensure that the product is a qualified product when it is shipped.

[0003] The airtightness testing equipment currently in use has only one workstation. When in use, the staff is required to first place the battery box on the base, and then use a pressure plate to press the battery box and the base together, and then fill the inside of the battery box with high-pressure gas to observe whether the air pressure drops. After the test is completed, the staff is required to remove the battery box on the base and then put in a new battery box. During this period of time, the airtightness testing of the remaining battery boxes cannot be performed, which reduces the overall work efficiency. Therefore, a new energy battery box airtightness testing device is proposed to address the above problems. Utility Model Content
