Embodiment Construction

[0023] Such as Figure 5 , 6 , 7, 8, and 9, a front side member of a vehicle body includes a front side member front portion 1 connected to the front bumper (not shown in the figure) of the vehicle and connected to the front panel of the vehicle (not shown in the figure). The rear part of the front side member 2. Connect the front longitudinal beam and the middle beam 4 of the front fender outside the front fender of the vehicle body. The front part 1 of the front longitudinal beam includes a closed cavity structure welded by the front main plate 11 of the front longitudinal beam and the outer plate of the front part of the front longitudinal beam. The rear part of the front longitudinal beam includes a closed cavity structure formed by the main board 21 of the rear part of the front longitudinal beam and the outer panel of the rear part of the front longitudinal beam. The front reinforcement of the front longitudinal beam is also welded in the front plate 11 of the front l...

Abstract

The invention discloses a front longeron of an automobile body, which comprises a front part of the front longeron connected with a front bumper of the automobile and a rear part of the front longeron connected with a front baffle of the automobile, wherein the front part of the front longeron comprises a sealed cavity structure welded by a front body plate of the front longeron and a front outer plate of the front longeron; the rear part of the front longeron comprises a sealed cavity structure welded by a rear body plate of the front longeron; the front lengeron also comprises a connecting piece which connects the front part of the front longeron and the rear part of the front longeron; the connecting piece is in a three-way groove shape; one end of the connecting piece is provided with a connector welded with the front part of the front longeron; and the other end of the connecting piece is provided with a connector welded with the rear part of the front longeron and a connector welded with a middle crossbeam of the front baffle. As the front longeron of the automobile body is designed into three parts, and a bending surface and a welded surface are integrated on the connecting piece, thereby improving the whole strength and proper force dividing transfer; in addition, the front longeron has the advantages of convenient processing and low welding difficulty.

Description

technical field [0001] The invention relates to a front longitudinal beam of a vehicle body, in particular to a front longitudinal beam of a miniature automobile. Background technique [0002] For cars with front-engine and front-wheel drive, in the body structure, the front longitudinal beam is not only the main component that bears the weight of the powertrain, but also a key part of energy absorption during a collision. Generally, the front longitudinal beam structure is a closed cavity structure. Considering manufacturing factors, the closed cavity is usually divided into two parts of sheet metal (the inner panel of the front longitudinal beam and the outer panel of the front longitudinal beam), which are then welded together during assembly. At the same time, in order to transmit the force generated during the collision to the entire body frame so that the force can be dispersed and absorbed, the front longitudinal beam is designed to be connected to the rear longitudin...
