Description

Technical Field

[0001] The utility model relates to the technical field of battery pack breathing valve equipment, in particular to a breathing valve sealing tool on a battery pack. Background Art

[0002] In order to ensure the working safety of the battery pack and prevent water vapor in the air from entering the inside of the battery pack due to packaging, maintenance, penetration, etc., a breathing valve is often required to discharge the water vapor in the battery pack to the outside. The invention patent with patent application number CN202310969983.9 discloses a battery pack and a breathing valve for a battery pack. The desiccant of the breathing valve can dehumidify the air entering the box, and the air discharged from the box can take away the moisture in the desiccant of the breathing valve, thereby extending the service life of the desiccant. When the air pressure inside and outside the box is relatively balanced, the air in the environment cannot enter the box. The desiccant does not absorb moisture ineffectively to maintain its moisture absorption capacity. According to the disclosed technical solution, when the existing battery pack breathing valve is in use, on the one hand, when the breathing valve is sealed, leakage may occur due to lax sealing, which is not conducive to ensuring the safety of the battery pack. On the other hand, when the breathing valve is opened, dust in the air may easily enter the inside of the battery pack through the breathing valve, which is not conducive to ensuring the hygiene and work safety in the battery pack. The conventional installation of a filter on the outside of the breathing valve may easily cause the filter to be damaged, which is not conducive to ensuring the filtering effect.

[0003] Therefore, how to design a breathing valve sealing tool on the battery pack has become our current problem to be solved. Utility Model Content

[0006] Furthermore, the breathing valves are respectively opened at the bottom of one side and the top of the other side of the battery pack, and the inner side of the battery pack is connected with the outer side of the battery pack through the breathing valves.

[0013] Beneficial effects: 1. When the breathing valve sealing tool on the battery pack is performing the sealing operation, the electromagnet is turned on and energized to generate magnetic force, so that the electromagnet moves toward the sealing plate through the magnetic force, and compresses spring one to drive gate one to move toward the inside of the breathing valve until gate one moves to the bottom of the breathing valve and is stuck into the inside of the seal to seal the breathing valve. At the same time, gate one pushes the piston downward, and pushes the hydraulic oil at the bottom of the inner cavity to the inside of the slide through the connecting pipe, and then pushes gate two in the slide upward, and then uses gate two to seal the breathing valve, which can effectively improve the sealing effect of the breathing valve. Even if gate one or gate two is not sealed tightly due to wear, gate two or gate one can be used for sealing to ensure the working safety of the battery pack.
