Problems solved by technology

At present, the common problem in the field of electric vehicles is that the battery life of electric vehicles is limited, which limits the promotion and application of electric vehicles
[0003] The body structure under the front of the existing electric vehicle is mostly a steel structure, which is heavy, which is not conducive to the lightweight of the electric vehicle, and is not conducive to effectively extending the cruising range of the electric vehicle. Moreover, the manufacturing, assembly and maintenance costs of the metal parts are high, which is not conducive to reducing the cost. It cannot meet the requirements of energy saving and environmental protection; in order to meet the collision requirements, the weight of the structural parts is large, and it is difficult to balance both the collision effect and the weight

Embodiment Construction

[0029] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0030] Such as Figure 1 to Figure 7 As shown, the body structure under the front part of the electric vehicle includes the front floor frame structure, the front longitudinal beam and the anti-collision beam. The lower beam and the rear floor front beam are arranged between a pair of sill beams to form the front frame. The anti-collision beam is connected to the front end of the front longitudinal beam through the energy-absorbing box, and the rear end of the front longitudinal beam is connected to the lower beam of the front fender through the connecting beam. , The lower beam of the front baffle, the threshold beam, the front beam of the rear floor, the front longitudinal beam, the energy-absorbing box and the connecting beam are all hollow aluminum profiles. The frame structure of the fron...

Abstract

The invention discloses a lower front body structure of an electric automobile. The lower front body structure comprises a front floor frame structure, a front longitudinal beam and an anti-collision cross beam, wherein the front floor frame structure comprises a front baffle lower cross beam, a pair of door sill beams and a rear floor front cross beam, the front baffle lower cross beam and rear floor front cross beam are arranged between the pair of door sill beams, and a front frame is formed; the anti-collision cross beam is connected with the front end of the front longitudinal beam through a crash box; the rear end of the front longitudinal beam is connected with the front baffle lower cross beam through a connecting beam; the front baffle lower cross beam, the door sill beams, the rear floor front cross beam, the front longitudinal beam, the crash box and the connecting beam all adopt a hollow aluminum profile structure. All beam structures adopt the hollow aluminum profile structure, the weight is light, the structural strength is high, the crash effect and the weight can be both considered simultaneously, lightweighting of the electric automobile is facilitated, the endurance mileage of the electric automobile can be effectively prolonged, and the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a vehicle body structure under the front part of the electric vehicle. Background technique [0002] As a new energy vehicle, electric vehicles have the advantages of energy saving and environmental protection. Electric vehicles are becoming more and more research hotspots in the automotive field. At present, the common problem in the field of electric vehicles is that the battery life of electric vehicles is limited, which limits the popularization and application of electric vehicles. [0003] The body structure under the front of the existing electric vehicle is mostly a steel structure, which is heavy, which is not conducive to the lightweight of the electric vehicle, and is not conducive to effectively extending the cruising range of the electric vehicle. Moreover, the manufacturing, assembly and maintenance costs of the metal parts are high, which is not conducive...
