Problems solved by technology

[0004] However, in such a conventional tubular reinforcing member, since the attachment portions at both ends are bent into an L-shape, for example, when an external force (impact load, etc.) having a component in the longitudinal direction of the pipe portion is applied, the The L-shaped bending part is easy to bend, and it may not be able to properly obtain the reinforcement performance of the pipe part

Embodiment

[0024] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0025] figure 1 It is a perspective view of a vehicle anti-collision beam 10 to which the present invention is applied, figure 2 It is a perspective view seen from the back side of the crash beam 10 , that is, the joint portion 18 side. in addition, image 3 yes figure 1 The enlarged cross-sectional view of the pipe portion 12 viewed from the arrow III-III, Figure 4 yes figure 1 The enlarged cross-sectional view of the mounting portion 14 as viewed from the arrows IV-IV is a state of being fixed to the mounting object 20 of the vehicle. The anti-collision beam 10 is equivalent to a tubular reinforcement member, such as Figure 5 As shown, the vehicle side door 22 is disposed inside the vehicle side door 22 to prevent the vehicle side door 22 from being deformed toward the vehicle interior due to an impact load applied from the outside of the vehicle during a ...

Abstract

The buckling of the mounting part is suppressed and the reinforcing performance of the pipe part is stably obtained. Since the mounting seat 32 is provided so as to protrude toward the seat surface 32 f side via the cylindrical portion 38 , the seat surface 32 f can be placed in close contact with the mounting object 20 and firmly fixed. In addition, side flanges 40 , 42 are respectively provided on both side ends of the cylindrical portion 38 , and are formed on both sides of the mounting seat 32 in a cross section perpendicular to the center line O of the pipe portion 12 . Since there are curved portions 44, 46 that are recessed into a U-shape on the opposite side of the seat surface 32f by the cylindrical portion 38 and the side flanges 40, 42, it is possible to improve the effect of the external force having a component in the longitudinal direction of the pipe portion 12. Rigidity suppresses the bending of the mounting part 14 and stably obtains the reinforcing performance of the pipe part 12 .

Description

technical field [0001] The present invention relates to a tubular reinforcing member for vehicles, and particularly relates to a technique for stably obtaining predetermined reinforcing performance by suppressing buckling of an attachment portion. Background technique [0002] There is known a tubular reinforcing member for vehicles comprising: (a) a tube-shaped tube portion formed by bending and closing a sheet metal material; The end portion of the longitudinal direction of the portion is integrally provided by the metal sheet so as to protrude in the longitudinal direction, wherein (c) the seat surface of the mounting seat is arranged so as to be in close contact with the mounting object of the vehicle. An example of the anti-collision beam described in Patent Document 1 is arranged on a side door of a vehicle to reinforce the impact load during a side collision. The seat is in close contact with the door and the like, and is fixed as a whole by bolts or the like. [00...
