Embodiment Construction

[0029] Describe in detail below with reference to the accompanying drawings, first look at Figure 1 to Figure 6 , which shows a vehicle body structure according to a preferred embodiment of the present invention.

[0030] Such as figure 1 and image 3 As shown, two front side members (or two side members) 1, 1 are arranged in the longitudinal direction of a vehicle adopting the vehicle body structure according to the present invention. The pillar 8 with a polygonal cross section extends in the vertical direction of the vehicle and stands in a side member (not shown) which is arranged outside the front longitudinal members 1, 1 and extends in the longitudinal direction. For clarity, figure 1 The left strut 8 is not shown in FIG. Also, the front side members 1, 1 have the same structure and shape. Therefore, unless otherwise required, only one front side member 1 will be described below.

[0031] The front side member 1 has a front horizontal portion 1a extending longit...

Abstract

A body structure, comprising: a longitudinal beam, a polygonal pillar, and a beam. The side members are arranged inside the vehicle and extend in the longitudinal direction of the vehicle. The polygonal struts are arranged on the outside of the longitudinal beams and extend in the vertical direction of the car. The beams extend between the stringers and the polygonal struts. The beam is also fastened to the corner of the polygonal strut so that the corner is located in the imaginary cross-section of the beam during an imaginary extension of the beam.

Description

technical field [0001] The invention relates to a vehicle body structure. Background technique [0002] Various technologies have been developed so far in order to secure both impact absorption and rigidity of the vehicle's front side members, and to ensure improved safety performance when the vehicle is subjected to a collision at its front end. [0003] In conventional technology, when the front end of the vehicle is hit, the front side members of the vehicle are crushed into wrinkles. In this way, those impact forces generated by the collision to be transmitted into the passenger compartment are absorbed by the crushed front side members. On the other hand, by increasing the rigidity of the components constituting the cabin, the safety of the vehicle is improved. [0004] A conventional technique for improving vehicle safety is disclosed by way of example in Patent Document 1 (Japanese Registered Utility Model Publication No. 2522690). The impact of the collision on th...
