Abstract
Disclosed herein are an automobile impact beam integrated with brackets which are fastened to an automobile and a method of manufacturing the automobile impact beam. The automobile impact beam according to the invention includes a body formed from a central area of a hollow steel pipe, and brackets formed from opposite ends of the hollow steel pipe extending from opposite sides of the body, through flattening, so that the brackets are formed as flat surfaces integrated with the body. The invention allows the impact beam to be easily manufactured and mounted to a vehicle, reduces the weight of the vehicle, and provides stability to a passenger.
Claims17
An automobile impact beam integrated with brackets, comprising:
- a body formed from a central area of a hollow steel pipe;
- and
- brackets formed from opposite ends of the hollow steel pipe extending from opposite sides of the body, through flattening, so that the brackets are formed as flat surfaces integrated with the body.
A method of manufacturing an automobile impact beam integrated with brackets, comprising:
- a heat treatment step of heat treating a body area of a hollow steel pipe, opposite ends of the hollow steel pipe forming the brackets and an area of the hollow steel pipe between the brackets forming a body;
- and
- a bracket forming step of forming the integral brackets by flattening the opposite ends of the hollow steel pipe, after the heat treatment step has been completed.
An automobile impact beam integrated with brackets, comprising:
- a body manufactured by heat treating a hollow steel pipe, and forming a central area of the automobile impact beam;
- and
- brackets integrally formed on opposite ends of the body by expanding ends which are provided on opposite sides of a heat-treated area of the hollow steel pipe and are not heat treated, and thereafter pressing the ends.
A method of manufacturing an automobile impact beam integrated with a bracket, comprising:
- a heat treatment step of heat treating an area of a hollow steel pipe, which forms a body of the impact beam;
- an expanding step of expanding an area of the hollow steel pipe other than the area which forms the body through the heat treatment;
- and
- a bracket forming step of forming a bracket integrated with the heat-treated area by pressing the area expanded through the expanding step.
