At the same time, the vacuum generating component in the assembly box 3 and the connection of the gas supply pipe 104 also make the operation simpler and easier; at the same time, the device adopts the downward pressure sealing component and the vacuum generating component to ensure the reliability of the air tightness test. The setting of the sealing component and the vacuum control system effectively prevents gas leakage and improves the stability and reliability of the detection results.

[0025] like Figure 2 , Figure 4 and Figure 5As shown, the downward pressure sealing assembly includes a lifting motor 4, a mounting groove 201 is provided on one side of the top plate 103 close to the mounting plate 1, and the lifting motor 4 is fixedly connected in the mounting groove 201; a sealing member 5 is also provided at the bottom of the lifting motor 4, and the top of the sealing member 5 is detachably connected to the lifting motor 4; a cavity 301 is provided inside the sealing member 5 corresponding to the placement groove 101, and a limiting block 302 is also fixedly connected inside the cavity 301, and the limiting block 302 is in contact with the battery pack body 2; a sealing ring 401 made of rubber material is also provided between the cavity 301 and the placement groove 101, and the sealing ring 401 is replaceably provided in the cavity 301.
