Problems solved by technology

When the crush box is bent, the crush box will not be properly compressed and destroyed in the axial direction, so that sufficient shock absorption cannot be obtained
[0009] However, in Patent Document 1, although it is mentioned that the buckling due to the bending stress acting on the base end portion of the crush box (the part to be joined to the stringer) in the event of an upward oblique collision or a downward oblique collision is mentioned. Deformation countermeasures, but did not mention the bending deformation of the middle part between the base end and the distal end (the part where the bumper reinforcement is combined) of the crush box, so there is still room for further study. room

Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0023] Figure 1 to Figure 4 A preferred embodiment when the impact-absorbing structure of the present invention is applied to the front of a vehicle is shown. In the drawing, it is assumed that an arrow F indicates the front of the vehicle, an arrow L indicates the left side of the vehicle, an arrow R indicates the right side of the vehicle, and an arrow U indicates the upper side of the vehicle. In addition, since the main part of the front part of the vehicle which concerns on this embodiment is left-right symmetrical, in the following description, only the structure of the left side of a vehicle is demonstrated except the case where expressly stated. In this case, the left side of the vehicle corresponds to the outer side in the vehicle width direction, and the right side of the vehicle corresponds to the inner side in the vehicle width direction.

Abstract

This shock absorbing structure for vehicles comprises a frame member formed from a resin material. The frame member has: a closed cross-section extending in the vehicle front-rear direction; and a ribthat protrudes at least either up or down from the closed cross-section and extends in the vehicle front-rear direction.

Description

technical field [0001] The present invention relates to a shock absorbing structure of a vehicle having a beam member formed of a resin material. Background technique [0002] Conventionally, there is known a shock absorbing structure that absorbs a shock applied to the front or rear of a vehicle at the time of a collision using a compressively deformable cushioning member (hereinafter also referred to as a crush box). The crush can is installed between a bumper reinforcement extending in the vehicle width direction along a front end face or a rear end face of the vehicle and distal end portions of a pair of left and right side members. A pair of side members extend from the cabin side toward the bumper reinforcement. [0003] Crash boxes are typically formed from metallic materials. When a vehicle collides, the crush box is compressed and destroyed in the axial direction, thereby absorbing the impact energy transmitted to the vehicle compartment. [0004] Since such a cr...
