referring to fig. 10, the sealing assembly 10 includes a branch pipe 101 connected to a side end of the bottom of the air pipe 6, a sealing air bag 102 fixedly connected to one end of the branch pipe 101 far away from the air pipe 6, an air release valve provided on one side of the sealing air bag 102, and a unidirectional air inlet valve provided on an inner wall of the branch pipe 101.

In the specific implementation process, when the automobile power battery 3 moves upwards and is loaded into the battery box 2, the air injection generating piece 7 continuously injects air and injects air to the inner side of the battery box 2, so that the inner side of the battery box 2 can be cleaned, sand particles with large particles can be removed, and water mist attached to the inner wall of the battery box 2 can be blown away until the water mist evaporates.

After the automobile power battery 3 is fixed with the battery box 2, gas in the ventilation pipeline 6 enters the branch pipeline 101, at the moment, the gas enters the sealing airbag 102 through the branch pipeline 101, the sealing airbag 102 starts to bulge and enables the sealing airbag 102 to lean against the outer side wall of the automobile power battery 3, and the sealing airbag 102 is of an annular structure, so that gaps between the automobile power battery 3 and the battery box 2 can be well guaranteed to be filled by the sealing airbag 102 in a ventilation mode, tightness between the automobile power battery 3 and the battery box 2 is guaranteed, a large number of particles are prevented from splashing between the automobile power battery 3 and the battery box 2 in a high-speed mode of the automobile 1, a large number of abrasion occurs on the outer wall of the automobile power battery 3, meanwhile, the sealing airbag 102 can isolate certain water vapor, and a large number of water mist is prevented from entering between the gaps between the automobile power battery 3 and the battery box 2 in rainy days.

Referring to fig. 10 and 11, in order to illustrate a structure for protecting the bolt 114, the protection module 12 includes a protection slot 120 formed at a side end of the support plate 113, an adaptive spring 121 is fixedly installed in the protection slot 120, a protection cover plate 122 is fixedly connected to the adaptive spring 121, a bottom of the protection cover plate 122 is in an inclined structure, and a rubber cover plate 123 is fixed at an upper end of the protection cover plate 122.

The bolt 114 of the automobile power battery 3 faces downwards, so that the nut part of the bolt 114 is always in contact with air, and a large amount of dust and soil or other harmful substances are stuck on the nut part of the bolt 114 along with long-time running of the automobile, and the nut part of the bolt 114 is easily damaged, so that a rubber cap is usually added above the existing mode, the service life of the rubber cap is shorter, the cap is easily dropped when the automobile 1 runs on a bumpy road, and the putrefaction of the nut can be accelerated along with splashing of sewage such as rainwater; when the electric automobile 1 needs to be powered on, the safety of the electric automobile 1 and the power-on efficiency are seriously affected when the bolts 114 are broken or deformed due to the nuts.

The nut part can be covered by the parts on the side wall of the supporting plate 113, so that the bolts 114 are prevented from being corroded or damaged; specifically, when the support plate 113 is rotated to the bottom of the automobile power battery 3, the tool for rotating the bolts 114 is in contact with the bolts 114, so that the protective cover 122 is retracted into the protective groove 120 on the support plate 113 by the inclined surface of the protective cover 122 on the side wall of the support plate 113.

When the tool for turning the bolts 114 is removed, the protective cover 122 is automatically ejected by the elastic force of the adaptive spring 121, and the protective cover 122 can be closely contacted with the surface of the automobile power battery 3 by the rubber cover 123 on the protective cover 122, so that a gap is avoided between the protective cover 122 and the surface of the automobile power battery.

When the automobile power battery 3 needs to be disassembled, the tool for rotating the bolt 114 will firstly contact the inclined plane at the bottom of the protective cover 122 and apply a pressure to the protective cover 122 in the process of approaching upwards the bolt 114, and then the protective cover 122 moves through the protective groove 120 on the inclined plane phase support plate 113 until the position of the bolt 114 on the automobile power battery 3 is exposed, and at this time, the bolt 114 of the automobile power battery 3 can be disassembled.

The implementation principle of the embodiment is as follows:

(1): when the battery box 2 is used for replacing electricity and replacing a new automobile power battery 3, firstly, the battery replacement device 4 lifts the automobile power battery 3 to ascend, the automobile power battery 3 contacts with the telescopic rod 84 on the inner side of the battery box 2, the air injection generating piece 7 extends out of the movable groove on the bottom of the battery box 2 through linkage of the telescopic rod 84, and high-pressure air is driven to be injected from the air injection hole of the air injection generating piece 7.

(2): the high-pressure gas blows the water mist collected on the inner wall of the battery box 2 quickly until the water mist is evaporated and then the air injection is stopped, at the moment, the linkage execution column 97 is reinserted into the air injection hole, the linkage execution column 97 extends out of the air injection hole, at the moment, the linkage execution column 97 abuts against the fixing clamping groove 31 on the auxiliary frame 30, and if the bolts 114 break, the connection stability of the automobile power battery 3 and the battery box 2 can be ensured through the linkage execution column 97.

(3): after the cleaning is completed, the tool on the battery changer 4 starts to screw the bolt 114, so that the bolt 114 on the automobile power battery 3 can be fixed into the threaded hole on the battery box 2, and at the moment, the support plate 113 supports the bottom of the automobile power battery 3, so that the stability of the automobile power battery 3 is improved.

(4): when the bolts 114 are fixed, the gas in the ventilation pipeline 6 enters the branch pipeline 101, and at the moment, the gas enters the sealed airbag 102 through the branch pipeline 101, the sealed airbag 102 starts to bulge, and the sealed airbag 102 is abutted against the outer side wall of the automobile power battery 3, so that the purpose of sealing a gap between the automobile power battery 3 and the battery box 2 is achieved.

(5): after the bolts 114 fix the automobile power battery 3 and the battery box 2 as a whole, the supporting plate 113 is rotated to the bottom of the automobile power battery 3, and as the tools for rotating the bolts 114 are separated from the bolts 114, the protective cover plate 122 on the side wall of the supporting plate 113 is ejected from the protective groove 120 on the supporting plate 113 and covers the bolts 114.
