Front wall structure for electric automobile

Abstract

The invention discloses a front wall structure of an electric automobile. The front wall structure of the electric automobile comprises a front wall plate, a front wall plate reinforcing beam, a front floor, a front floor lower cross beam and front longitudinal beams; the number of the front longitudinal beams is two, the two front longitudinal beams are oppositely arranged at the front end of an automobile chassis in the width direction of the automobile, and an engine compartment and a compartment of the electric automobile are separated through the front wall plate; the front wall plate reinforcing beam is arranged in the width direction of the automobile and fixedly connected with the front wall plate; the front floor is laid at the bottom of the compartment, the front floor lower cross beam is arranged in the width direction of the automobile, and the front floor lower cross beam is fixedly connected with the bottom of the front wall plate, the front wall plate reinforcing beam and the front longitudinal beams. According to the front wall structure, the structural strength of the front wall plate is improved, the problem that the invasion amount of the front wall plate is large in front rigid collision and offset collision is solved, and the electric automobile using the front wall structure can meet the requirements of C-NCAP five stars.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a front wall structure of an electric vehicle and an electric vehicle with the front wall structure. Background technique [0002] C-NCAP is to promote the healthy development of China's auto industry and accelerate the globalization process of the domestic auto market. The China Automotive Technology and Research Center officially released the first version of the China New Car Evaluation Procedure (C-NCAP) on March 2, 2006. Since the official implementation of C-NCAP, it has been widely recognized by consumers. Consumers have higher and higher safety requirements for cars, so manufacturers also regard C-NCAP star results as the focus of safety design. In C-NCAP, the requirement for offset collision is the most difficult. The amount of intrusion in the front wall area of ​​the offset collision is closely related to the safety of the occupants. The risk of injury to th...
