The connection structure between the a-pillar and the lower a-pillar of the vehicle body

Abstract

The invention discloses a connecting structure of the upper portion and the lower portion of a column A of a car body. The connecting structure comprises a connecting plate and a connecting beam; the connecting beam is a longitudinal beam, one end of the connecting beam is fixed on the front side face of the upper end of the lower structure of the column A, the other end of the connecting beam is connected with the front end of the upper structure of the column A, the connecting plate is a triangular plate, the upper edge of the connecting plate is connected with the upper structure of the column A, and the lower edge of the connecting plate is connected with the connecting beam and the upper end of the lower structure of the column A. The connecting structure is reasonable in structural design, connection is reliable, all parts are aluminum parts, the weight is low, good direct impact and side impact effects are achieved, and the impact and the weight can be taken into account simultaneously; weight lightening of electric vehicles is promoted, and the endurance mileage of the electric vehicles can be effectively extended.

Description

technical field [0001] The invention relates to the technical field of vehicle bodies, in particular to a connection structure between an A-pillar and a lower A-pillar of a vehicle body. 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] Most of the existing structural parts on the car body are steel plate structures, which are heavy, which is not conducive to the lightweight of electric vehicles, and is not conducive to effectively extending the cruising range of electric vehicles. Moreover, the manufacturing, assembly and maintenance costs of metal parts are high, which is not conducive to reducing co...

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] Most of the existing structural parts on the car body are steel plate structures, which are heavy, which is not conducive to the lightweight of electric vehicles, and is not conducive to effectively extending the cruising range of electric vehicles. Moreover, the manufacturing, assembly and maintenance costs of metal parts are high, which is not conducive to reducing costs and cannot meet energy saving requirements. Environmental protection requirements; in addition, the upper and lower structures of the A-pillar are two separate parts, and the two are connected by structural parts. In order to meet the requirements of frontal collision and side collision, the weight of the structural parts is heavy, and it is difficult to achieve both frontal and side collisions and weight simultaneously. take into account
