Since the lithium battery is currently applied in a wide range of fields, a higher requirement is also put forward on the waterproof performance of the battery itself. In addition, the BMS protection board is constructed by a plurality of electronic components, and once the electronic components are wetted or soaked in water, the faults such as short circuit can be caused, and certain difficulty is caused for the safe use of the lithium battery.
The utility model has the following contents:
the utility model aims to provide a waterproof upper cover of a replaceable battery, which has a simple structure and has good waterproof performance for a BMS protection plate.
The object of the utility model is achieved in that:
the utility model provides a can waterproof trade electric cell upper cover, it includes the metal upper cover body of dark shell structure and arranges the inside BMS protection shield of metal upper cover body in, cuts apart a cabin body by the baffle of perpendicular to metal upper cover body roof in the inside of metal upper cover body, BMS protection shield arrange the cabin body in add a sealed lid.
The sealing structure is characterized in that a sealing groove is formed in the surface of the top of the partition plate, an elastic sealing ring is arranged in the sealing groove, and the sealing cover covers the elastic sealing ring.
The elastic sealing ring is 1-2mm greater than the sealing groove.
A raised heat dissipation contact surface is arranged on the inner surface of the top plate of the metal upper cover body at a position corresponding to the high-power heating component of the BMS protection plate.
The outer surface of the metal upper cover body is provided with a heat dissipation structure with a concave-convex structure.
And the metal upper cover body is provided with a lead output interface.
The outer surface of the metal upper cover body is provided with a movable portable handle.
The movable hand-held handle of the metal upper cover body is connected with the fixed plate on the surface of the metal upper cover body through a movable hinge.
The movable hinge is a rotating shaft structure.
The battery replacement device is simple in structure, provides a good waterproof space for the BMS protection board, and overcomes the defects of the prior art, so that the use safety of the battery replacement device is ensured, and the service life of the battery replacement device can be prolonged.
