摘要： An anti-collision component consisting of a metal hollow profile for automobiles includes a collision side flange, a body side flange, and a web connected to the flanges. The hollow profile has a longitudinal end at which a cross-sectional configuration is deformed by swaging to reduce a dimension between the flanges. The following relations are established: tW>TW RCI≧(tW-TW) where tW is a wall thickness of the web at the end, TW is a wall thickness of the web at a portion where the cross-sectional configuration is not deformed, and RCI is an inside corner radius of a corner formed of the web and each flange at the portion.

摘要： The present invention relates to a structure for mounting a hook bracket formed of an aluminum alloy extrusion to a bumper reinforce having a hollow cross-section, and further reduces the weight of the hook bracket and the weight of the mount structure without deteriorating towing performance. The hook bracket has a cut that is formed in an extrusion cross-section (a cross-section perpendicular to the direction of extrusion) and extended from the rear end of a shaft portion into the hollow in the bumper reinforce. Further, an internally threaded hole is formed. The shaft portion of the hook bracket is penetrated through a hole formed in front and rear walls of the bumper reinforce and fillet-welded to the front and rear walls. The shaft portion is not fillet-welded to the rear wall at a position where the cut is formed.

摘要： A bumper reinforcement includes a tubular body including a front wall that serves as an impact surface and a rear wall on a vehicle body side, the tubular body extending in a vehicle width direction and having a hollow cross section; and a tow hook attachment structure for allowing a tow hook to be removably attached thereto. The tow hook attachment structure includes a pair of cylindrical protrusions respectively integrally formed with the front and rear walls of the tubular body by shaping parts of the walls, the cylindrical protrusions being disposed at predetermined positions on the front and rear walls in the vehicle width direction so as to face each other and so as to protrude inward into the hollow cross section, and at least one of the pair of protrusions includes a threaded portion for allowing a threaded portion of the tow hook to be screwed thereinto.

摘要： To compensate for a decrease in reaction force of a bumper reinforcement, which is made of an aluminum alloy extrusion having two end portions subjected to bend forming and crushed portions on the respective end portions, against an impact load in end impact involved in crushing, and compensate for a decrease in energy absorption amount of the bumper reinforcement. Assuming a space between two flanges includes a first region from a center line of the thickness between the flanges to an outer flange and a second region from the center line to an inner flange in a cross section of the crushed portion perpendicular to an extrusion direction, area of the webs located in one (for example, the first region) of the two regions is larger than area of the webs located in the other region (for example, the second region).

摘要： A door beam includes an outer flange, an inner flange, and a pair of webs connecting the outer flange and the inner flange. The outer flange, the inner flange, and the pair of webs define a closed cross-sectional portion. The outer flange includes an outer central portion constituting the closed cross-sectional portion, and outer protruding portions protruding outward from the closed cross-sectional portion. The inner flange is formed with an attachment press working portion having been subjected to press working so as to serve as an attachment portion with respect to the inner panel at both end portions in the longitudinal direction. The outer protruding portion is formed with a mastic press working portion having been subjected to press working so as to serve as an attachment portion with respect to the outer panel.

摘要： A bumper reinforcement is formed of a 7000 series aluminum alloy hollow extrusion and has crushed end portions. A portion of the end portions is heated to a temperature of 400° C. or more for reversion treatment, the heated portion is subjected to cold crushing, and then the whole bumper reinforcement is subjected to age hardening. Because of the age hardening, the heated portion has higher Vickers hardness than non-heated portions by Hv 10 or more. This compensates for a decrease in reaction force in a collision of an end portion resulting from a decrease in the section modulus of the crushed portion and thereby suppresses a decrease in energy absorption.
摘要翻译： 保险杠加强件由7000系列铝合金中空挤出件形成，并且具有破碎的端部。 将一部分端部加热到400℃以上的温度进行回复处理，对加热部进行冷压碎，然后对整个保险杠加强件进行时效硬化。 由于时效硬化，加热部分的维氏硬度比非加热部分高10V以上。 这补偿了由于破碎部分的截面模量的降低导致的端部部分的碰撞中的反作用力的降低，从而抑制了能量吸收的降低。
