Problems solved by technology

[0005] Therefore, since the steel plate with high material strength is used for the front pillar outer panel, it is difficult to process the front pillar outer panel into a predetermined shape by one press forming, which deteriorates productivity.

Embodiment Construction

[0055] Such as figure 1 As shown, the front pillar 1 according to an embodiment of the present invention is extended in the vertical direction of the automobile, and the front pillar outer panel 2 with a cross-sectional hat shape formed by using a material such as a steel plate with high material strength and combining the material strength The end flanges of the front pillar inner panel 3 in a state in which a material such as a steel plate that is not too high is formed in a state where relatively many flat portions are formed form a closed cross-sectional shape.

[0056] The front pillar 1 takes the center portion 1a as the center, and its upper end portion 1b and lower end portion 1c have bent portions 1b-1, 1c-1, and extends toward the rear of the vehicle. Both the front pillar outer panel 2 and the front pillar inner panel 3 can be A single structure formed by, for example, stamping.

[0057] In addition, the lower end portion 1c of the front pillar 1 is opened downwar...

Abstract

Provided is a coupling structure between a front pillar and a side sill of an automobile, in which the handling stability of the automobile is improved while high productivity is also achieved. A reinforcement (8) is arranged so as to extend in a closed section shape of a front pillar (1) in the front-rear direction of an automobile, a reinforcement extension (8a) is formed by coupling the reinforcement (8) to a front pillar outer (2) together with extending the automobile rear-end side of the reinforcement (8) to a side sill (4) side, and the reinforcement extension (8a) is coupled to a side sill outer (5) side.

Description

technical field [0001] The present invention relates to a joint structure of a front pillar and a side sill of an automobile formed by connecting a lower end of a front pillar extending in the vertical direction of the automobile and a front end of a side sill extending in the longitudinal direction of the automobile. Background technique [0002] Conventionally, the junction structure of the front pillar and the side sill of the automobile is constituted by connecting the lower end of the front pillar and the front end of the side sill to each other. The front pillar inner panels overlap each other to form a closed-section shape, and the side sills extend in the front-rear direction of the vehicle and also form a closed-section shape. [0003] However, in recent years, in order to achieve further weight reduction of automobiles, especially the front pillar outer panel is constituted using a steel plate having a high material strength. [0004] However, the lower end of the...
