Embodiment Construction
[0021] An embodiment of the chassis quick-change battery box in the present invention is as Figure 1 to Figure 8 As shown, the battery box in this embodiment includes a lower box body 2 and an upper box cover 1, and the lower box body 2 and the upper box cover 1 form a sealed space. After opening the upper box cover 1 of the battery box, it can be stored in the battery box The battery unit includes a battery module 3, a high-voltage component 4 at the front end, a connector plug 5 for docking with the socket on the car body, a battery management system 6, a heating belt, etc. When the battery box is installed in the vehicle Behind the chassis, the connector plug 5 on the battery box is plugged and matched with the vehicle end socket, thereby realizing the electric energy supply to the electric vehicle.
[0022] The upper box cover 1 of the battery box is processed by cold-rolled sheet metal bending and partial tailor welding. The left and right sides of the upper box cover 1 ...

The invention relates to a chassis quick-change battery box. The chassis quick-change battery box includes an upper box cover, a lower box body, an inner tank fixed in the lower box body, and a sealing structure arranged between the upper box cover and the lower box body. The sealing structure includes a gasket and an upper The connection flange on the box cover, the upper surface of the side wall of the lower box has a flat support surface, the side wall of the inner tank has a flange that fits and cooperates with the flat support surface, and the gasket is A flat pad disposed between the flange and the lower surface of the connecting flange. By setting the flange on the side wall of the inner tank to fit the flat support surface, the overall flatness and structural strength can be increased, the deformation can be reduced, the gasket can be closely matched with the corresponding sealing surface, and the sealing performance is greatly improved. , At the same time, there is no need to set a vertical water baffle on the lower box body, which is beneficial to reduce the overall weight, the processing difficulty is small, and the sealing effect is good.
Description
technical field [0001] The invention relates to a chassis quick-change battery box. Background technique [0002] In order to accelerate the development of the new energy vehicle industry, promote energy conservation and emission reduction, and promote air pollution control, the state has successively issued relevant policies to encourage the development of electric vehicles. At present, there are two main modes of energy supply for electric vehicles: charging and battery swapping. The charging mode is divided into slow charging and fast charging. The charging current of slow charging is relatively low, about 16A, and the charging time is about 5 to 8 hours. This charging method has little damage to the battery and is fully charged. Household 220V mains or AC charging Just a pile, but the charging time is long, and the long waiting process does not meet people's car needs. The charging current of fast charging is relatively large, about 150 to 400A, and the charging time i...
