Problems solved by technology

The structure of the battery compartment in the prior art has the following defects: 1. The structural strength of the front compartment is relatively poor, and the battery is arranged here, which is prone to danger during a collision; 2. When it is arranged at the rear of the vehicle body, the weight of the battery compartment structure is heavy. Large, redundant repeating structure increases its mass and makes it expensive to manufacture
3. Arranged outside the car and connected with the body by bolts, this type of structure is complex, increases the weight of the body, and cannot meet the purpose of lightweight body

Abstract

The invention provides an electric battery cabin structure. The electric battery cabin structure is simplified, a spatial triangular structure is formed through a slanting beam, a frame longitudinal beam and a battery cabin upright column, the battery cabin is arranged on the joint of the front section and the rear section of a frame, and safety of a battery is guaranteed. By means of the battery cabin structure, bending resistance of the whole frame is enhanced, and collision safety is improved.

Description

technical field [0001] The invention relates to a battery compartment structure of an electric vehicle. Background technique [0002] The structure of the small electric vehicle battery compartment of the prior art: 1, arranged in the front engine room 2, arranged in the rear of the vehicle body. 3. Arranged outside the body and connected with the body through bolts. The structure of the battery compartment in the prior art has the following defects: 1. The structural strength of the front compartment is relatively poor, and the battery is arranged here, which is prone to danger during a collision; 2. When it is arranged at the rear of the vehicle body, the weight of the battery compartment structure is heavy. Large, redundant repeating structures increase its mass and make it expensive to manufacture. 3. Arranged outside the vehicle and connected with the vehicle body by bolts, this type of structure is complex, increases the weight of the vehicle body, and cannot meet th...
