Automobile power battery box

Abstract

The automotive power battery case provided by the present invention includes an upper cover, a lower casing, a waterproof ring and fasteners, wherein the upper cover includes a horizontal plate, an upper limit portion and an upper sealing portion, and the upper limit portion is vertically fixedly connected to the horizontal plate, The upper sealing part is vertically fixedly connected with the upper limit part; the lower shell includes a riser, a 180° bending part and a lower sealing part, and the 180° bending part is fixedly connected with the riser, and the 180° bending part is located on the riser side, the lower sealing part is vertically fixedly connected with the 180° bending part; When the sealing part cooperates with the lower sealing part, an accommodating cavity is formed; the waterproof ring is placed in the accommodating cavity; the fastener passes through the upper sealing part, the waterproof ring and the lower sealing part in turn to seal the box body. The invention avoids water or dust entering the box body, reduces the occurrence of problems such as ignition, insulation or short-circuit fire, and ensures vehicle and personal safety.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an automotive power battery box. Background technique [0002] With the approach of the energy crisis and the improvement of people's awareness of environmental protection, electric vehicles have attracted more and more attention from all walks of life. As the core component of electric vehicles, power batteries have higher and higher requirements for IP (protection level). Now the national standard has stipulated that the IP rating of the power battery box of all types of electric vehicles must reach IP67, so the sealing of the car power battery box is very critical. If the sealing performance is poor, not only will it not meet the requirements of the national standard, the box body Water or dust may also enter, causing ignition or insulation problems in the power battery. In severe cases, it may short-circuit and catch fire, endangering the safety of the vehicle and p...
