Abstract

The invention relates to a box body and a battery box using the box body, the top end of the box side plate of the box body is pressed down to form a first pressed edge of the box body, A low end of that first dead edge of the box body is bent outwardly to form an outwardly flanged edge of the box body, one end of the outer flanged edge of the box away from the first flanged edge of the box is pressed inward to form a second flanged edge of the box, An upper cover of the battery case comprises an upper cover top plate, the edge of the upper cover top plate is bent downward to form an upper cover lower flange, the low end of the upper cover lower flange is bent outward to form an upper cover outer flange, and the upper cover outer flange is connected with a double-layer connecting plate formed by an outer flange of the case and a second pressurized dead edge of the case. When the double-layer connecting plate is connected with the outer flanging edge of the upper cover, the double-layerconnecting plate and the outer flanging edge of the upper cover can withstand enough extrusion force to avoid extrusion deformation, thereby ensuring the sealing effect between the upper cover and the box.

Description

technical field [0001] The invention relates to a box body and a battery box using the box body. Background technique [0002] As a new generation of transportation, electric vehicles have become a hot spot for development due to their advantages in energy saving and environmental protection. The battery box is usually installed on the chassis of the electric vehicle to store the power battery of the electric vehicle. Because it is close to the ground, it is often polluted and eroded by dust and water on the ground. Therefore, the battery box must have a certain IP protection level. In order to ensure that the battery in the box is not damaged. [0003] With the continuous development of the field of electric vehicles, people have higher requirements for the IP protection level of the battery box. For example, the Chinese utility model patent with the authorized announcement number CN205452396U discloses a battery box with a waterproof structure. The battery box includes T...
