Abstract

The invention discloses an electric vehicle and a front cabin structure thereof. The front cabin structure comprises a front anti-collision beam, a front longitudinal beam assembly, an oblique supporting beam assembly, a water flowing groove, a front coaming, a damping tower, a first front beam and a second front beam. The front longitudinal beam assembly comprises an energy absorption box, a supporting plate and a front longitudinal beam body, and the front end of the energy absorption box is welded to the two ends of the front anti-collision beam. The oblique supporting beam assembly is welded to the tail of the front longitudinal beam assembly. The lower portion of the damping tower is welded to the front longitudinal beam body, and the upper portion of the damping tower is welded to awater flowing groove framework. The second front beam is arranged at the upper portion of the front longitudinal beam body, the two ends of the second front beam are welded to the damping tower, and the rear side face of the second front beam is welded to the front coaming. The front portion of a water flowing groove body is welded to a water flowing groove framework front supporting beam, and thetwo ends of the water flowing groove body are welded to the water flowing groove framework through a water flowing groove connecting plate. The structure implementing manner is simple, convenient andfast, the manufacturing technology is simple, and the collision safety performance of the structure is improved to a great degree while structure lightweight is achieved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a front compartment structure of an electric vehicle capable of high-efficiency energy absorption and a high degree of light weight. Background technique [0002] The rapid development of the automobile industry is facing a series of bottlenecks such as energy shortage and environmental pollution. Safety, energy saving and environmental protection have become the themes of the development of the automobile industry. To achieve this goal, the development of electric vehicles has become an inevitable trend. However, short cruising range and poor safety performance are important factors restricting the development of electric vehicles. The study found that every 10% weight reduction of pure electric vehicles can save 4-5% of electricity, reduce the acceleration time of 100 kilometers by 8%, reduce the braking distance by 5%, and increase the cruising range by 8%. Therefo...
