The invention relates to a quick-changing battery for a chassis. The quick-changing battery for the chassis comprises an upper box cover, a lower box body, an inner container fixed in the lower box body and a sealing structure arranged between the upper box cover and the lower box body, wherein the sealing structure comprises a sealing gasket and a connecting flanging arranged on the upper box cover; the upper surface of the side wall of the lower box body is provided with a smooth supporting surface; the side wall of the inner container is provided with a flange matched with the smooth supporting surface in an attached manner; and the sealing gasket is a flat gasket arranged between the flange and the lower surface of the connecting flanging. The flange matched with the smooth supporting surface in an attached manner is arranged on the side wall of the inner container, the integral smoothness and structural strength can be increased, and the deformation is reduced, so that the sealing gasket can be in tight fit with a corresponding sealing matching surface, and the sealing performance is greatly improved; and moreover, a vertical water blocking plate does not need to be arranged on the lower box body, so that the reduction of overall weight is facilitated, the processing difficulty is low, 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...
