Problems solved by technology
Due to the stamping method, there is a problem that the process is complicated
The non-load-bearing body structure refers to: a separate frame is set, and the frame and the body are connected by bushings. The non-load-bearing body mainly relies on the chassis frame to bear the load brought by the complex road surface, which has the problems of heavy weight and poor ride comfort.

Embodiment Construction
[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] The invention provides a body structure of an electric vehicle, which combines the characteristics of a load-bearing body structure and a non-load-bearing body structure, and is designed as a unique structure because it is a low-speed electric vehicle. Under the premise of meeting the rigidity and strength performance of the vehicle body, the design greatly reduces the weight and manufacturing cost of the vehicle body, making outstanding contributions to the lightweight design.

The invention provides an electric vehicle body structure, comprising a frame, a vehicle body skeleton, an inner covering and an outer covering; the frame comprises a left longitudinal beam, a right longitudinal beam, a left connection tube, a right connection tube, a first cross beam, a second cross beam, a third cross beam, a left oblique beam, a right oblique beam, a left support beam, a rightsupport beam and a rear anticollision beam. A vehicle body skeleton comprises a left lower side beam, a right lower side beam, a left upper side beam, a right upper side beam, a left A-pillar, a rightA-pillar, a left B-pillar, a right B-pillar, a left C-pillar and a right C-pillar. The electric vehicle body structure has the advantages that the electric vehicle body structure combines a bearing vehicle body structure and a non-bearing vehicle body structure and is of integral welded structure, vehicle body weight and manufacture cost are greatly decreased at the premise of satisfying vehiclebody strength, and contributions are made to the lightweight design; the electric vehicle body structure has good riding comfort; verification shows that the electric vehicle body structure has good rigidity and collision energy absorbing performance.
Description
technical field [0001] The invention belongs to the technical field of automobile body structure design, and in particular relates to an electric automobile body structure. Background technique [0002] The current automobile body structure is mainly divided into load-bearing body structure and non-load-bearing body structure. The load-bearing body structure means that no separate frame is provided, and the bottom longitudinal beam is directly punched to the floor by stamping, so that a cavity is formed between the bottom longitudinal beam and the floor, thereby improving the structural strength. Due to the stamping method, there is a problem that the process is complicated. The non-load-bearing body structure refers to: a separate frame is set, and the frame and the body are connected by bushings. The non-load-bearing body mainly relies on the chassis frame to bear the load brought by the complex road surface, which has the problems of heavy weight and poor ride comfort. ...
