Mounting structure of bumper beam

Abstract

Provided is a mounting structure of a bumper beam whose weight is reduced while ensuring sufficient strength. In a bumper beam mounting structure for mounting the bumper beam on at least one of the front part or the rear part of the side beam, wherein the side beam is located on both sides in the vehicle width direction and along the vehicle extending in the longitudinal direction of said bumper beam having two or more tubes each having a length at least equal to the distance between said side members, said tubes being arranged horizontally and one above the other, Thus, the outer surfaces of these tubes are located at the same position in the longitudinal direction of the vehicle, and the center position of the bumper beam in the height direction is substantially coincident with the center position of the side member in the height direction.

Description

technical field [0001] The present invention relates to a mounting structure for mounting a bumper beam on at least one of a front side and a rear side of a vehicle. Background technique [0002] There are bumpers on the lower part of the front and rear of the vehicle. Bumpers protect functional parts such as the body or lights in the event of a collision between the vehicle and other objects. There is a bumper beam at the rear of the bumper, which is used to absorb the impact energy when the body is hit by a collision. [0003] Bumpers come in many shapes, depending on the size of the vehicle. In addition, because the bumper also has the function of enhancing the design characteristics, corresponding to different car models, the bumper used also has a variety of different design shapes. Therefore, in order to match the shape of the bumper, there are also many types of bumper beams produced. [0004] In order to manufacture the bumper beam, materials such as steel sheets...

AI Technical Summary

Problems solved by technology

However, the reduction in material thickness reduces the bending strength of the entire bumper beam

Therefore, there is a limit in achieving both low weight and high strength of the bumper beam

[0009] On the other hand, in the structure described in Japanese Patent Provisional Publication No. 2000-85496, since the reinforcement is formed with only one steel pipe, the absorption of impact energy is insufficient.
