Automobile body with battery pack containing box

Abstract

The invention provides an automobile body with a battery pack containing box. The automobile body is characterized in that the battery pack containing box comprises a box body (25) and a box cover; an opening of the box body (25) faces the front portion of the automobile body; the upper end of the box body (25) is fixedly connected with a storage plate welding assembly of the automobile body; the lower end of the box body (25) is fixedly connected with an automobile body floor below the storage plate welding assembly; and the box cover is fixedly connected with the storage plate welding assembly and used for covering the opening of the box body (25). According to the automobile body, the battery pack containing box is arranged between the storage plate welding assembly and the rear floor, the upper end and the lower end of the box body are both fixed, the installation structure is firmer, and the automobile body is not likely to be affected by jolting during travelling. The battery pack containing box is located inside the automobile body, so that a user fetches a battery pack or maintains the battery pack conveniently; and moreover, the battery pack containing box is far away from the tail of the automobile body, and accordingly the safety of the battery pack can be effectively improved when a rear-end collision occurs.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an automobile body with a battery pack accommodating box. Background technique [0002] Limited by the current battery technology, the energy density of batteries is limited, and the range of pure electric vehicles is short. In order to improve the endurance of pure electric vehicles, it is necessary to add a power battery pack. [0003] In order to install the additional battery pack, most of the existing solutions are to cancel the spare tire basin of the rear floor and install the battery pack under the rear floor. The essence of this installation structure is to suspend the battery pack on the rear floor, and its installation strength And the stability is easily affected by the bumps and becomes poor. Moreover, the installation structure occupies the space of the spare tire. In the event of a rear-end collision, the battery pack has a greater safety hazard. Therefo...
