[0030] The battery box sealing device of the embodiment connects the battery box 71 to be sealed to the base 7, thereby fixing the position of the battery box 71 to be sealed. The first driving member 12 drives the first connecting plate 13 and the second connecting plate 15 to rotate, so that the first sealing gasket 141 is positioned corresponding to the through hole on the battery box 71 to be sealed. Then the first driving member 12 drives the first connecting plate 13 and the second connecting plate 15 to descend, until the first sealing gasket 141 abuts against the through hole on the battery box 71 to be sealed, the second connecting column 151 abuts against the supporting column 16, and the third connecting column 18 is inserted into and clamped with the positioning hole 131 on the first connecting plate 13. The cooperation between the first driving member 12 and the first sealing gasket 141 enables the first sealing gasket 141 to seal the through hole on the battery box 71 to be sealed, and the start and stop of the sealing of the through hole can be quickly completed, and there is no need to clean after stopping the sealing, thereby reducing the time required for the overall steps of the air tightness detection. The second connecting column 151 is arranged to balance the weight of the first connecting column 14, and abuts against the supporting column 16 to support the first connecting plate 13, so that the first connecting plate 13 remains horizontal. The cooperation between the positioning hole 131 and the third connecting column 18 guides and positions the third connecting plate 22 during the descending process, so that the first sealing gasket 141 seals the through hole on the battery box 71 to be sealed more accurately.

[0031] The base 7 is in the form of a flat plate, and a plurality of connecting holes are arranged at the middle position of the base 7, which are used to connect the battery box 71 to be sealed, thereby fixing the position of the battery box 71 to be sealed.

[0032] Referring to Figures 3 to 5As shown, the first sealing assembly 1 is used for sealing the through hole at the top of the battery box 71 to be sealed.

The end of the first connecting plate 13 away from the first driving member 12 is connected with a first connecting column 14 which extends away from the base 7 and is connected perpendicularly with the first connecting plate 13. The end of the first connecting column 14 away from the first connecting plate 13 is connected with a first sealing gasket 141. The first connecting plate 13 is also connected with a second connecting plate 15 which is collinear with the center line of the first connecting plate 13, i.e. the extending direction of the second connecting plate 15 is opposite to that of the first connecting plate 13. The end of the second connecting plate 15 away from the first connecting column 14 is connected with a second connecting column 151 which is connected perpendicularly with the second connecting plate 15 and extends away from the base 7. The first driving member 12 and the first connecting frame 11 are both connected with the first connecting frame 11 which is connected with the base 7. The first driving member 12 can drive the first sealing gasket 141 to abut against the position of the through hole at the top of the battery box 71 to be sealed, so as to block the through hole with the first sealing gasket 141, while the second connecting column 151 abuts against the top end of the support column 16. Through the arrangement of the second connecting column 151, the weight of the first connecting column 14 can be balanced, so that the first connecting plate 13 is more stable during rotation. The abutment of the second connecting column 151 against the support column 16 supports the first connecting plate 13, so that the first connecting plate 13 remains horizontal and prevents the first sealing gasket 141 from being raised to cause air leakage.

[0033] The first driving member 12 is also connected with a first mounting seat 17. A third connecting column 18 is connected with the first driving member 12 through the first mounting seat 17.

The descending of the output end of the fourth driving member 41 can drive the fourth sealing gasket 43 to be raised. The ascending of the output end of the fourth driving member 41 can drive the fourth sealing gasket 43 to be pressed downward, so as to seal the through hole on the connecting part of the bottom side of the battery box 71 extending outward. Preferably, the connecting part of the first connecting frame 11 is spaced apart from the base 7 by a certain distance, so that the fourth sealing assembly 4 can also be arranged on the base 7 at a position corresponding to the connecting part of the first connecting frame 11.

[0037] Referring to Figure 9 As shown, the fifth sealing assembly 5 is connected with the base 7, and is used for sealing the obliquely arranged through hole on the side wall of the battery box 71.
