At present, the location of the electric vehicle lithium battery pack in the vehicle is basically in the chassis, when the vehicle will be running in the process of water phenomenon, and the existing battery box body structure is generally thinner sheet metal parts through the shear bending welding, and the sealing part is through the battery box on the edge of the inward fold 12-20mm length, and then through the battery box on the cover of the large surface and fold the edge of the part of the glue way to seal, this This sealing method has two problems, one is that because there is no rubber groove, when the two layers of steel plate is squeezed by the bolt, the rubber will be extruded to play a certain waterproof, such as when the rubber is not uniform, the waterproof effect in some places is very poor. Second, battery maintenance, the rubber is more difficult to remove, the battery box cover is not easy to take down, forced to take down the battery box cover is easy to deformation, battery maintenance and re-sealing glue, due to the original glue has become hard, not easy to clean, again glue sealing effect is even worse.
The task of this utility model is to propose a good sealing effect, water release, dustproof, and safe, stable structure of a power lithium-ion battery pack waterproof device.
The task of the utility model is accomplished in this way, a power lithium-ion battery pack waterproof device, characterized in that: the opening of the battery box body is folded inward around the edge, the inner folded edge is pressed with a flange, the disk of said flange is added with a groove for placing the seal, the flange is processed with a threaded hole in the battery box cover, said battery box cover is provided with a through hole corresponding to the flange seal, the battery box cover is surrounded by The battery box cover is provided with through holes corresponding to the flange, and the battery box cover is flanged outward. Said battery box body is a cavity inside, the bottom of which is machined to place the nut pit, said flange bottom flange height is the battery box cover buckled in the opening of the battery box overlap each other seal prevail. Said the shape of the seal can be O-shaped, rectangular seal, said fasteners can be selected screws, nuts and spring washers.
A kind of power lithium-ion battery pack waterproof device, its characteristics are: the battery box body opening around the inward folding edge, the inner folding edge is pressed with a flange, said flange on the disk surface with a groove to place the seal, the flange is processed with the battery box cover threaded hole, said battery box cover is set with the flange corresponding seal through the hole, the battery box cover around the outward flap.
