Abstract

PURPOSE: A rear bumper for a vehicle is provided to increase the productivity and manufacturing cost of the bumper and to improve shock absorbing performance by constructing the rear bumper with two parts and producing it from two kinds of raw materials. CONSTITUTION: A rear bumper for a vehicle comprises a bumper cover(1) and a back beam(2). The bumper cover(1) is manufactured from engineering synthetic resin. The back beam(2) is manufactured from injection-molding synthetic resin such as polycarbonate and the like. The back beam(2) is disposed in the inner center of the bumper cover(1). The back beam(2) has a back beam main body(20). A multiplicity of honeycomb-shaped through holes(21) are formed in the back beam main body(20) at uniform intervals. Brackets(22,23) are integrally formed with the back beam main body(20) at opposite sides of the upper and lower sides thereof. Bumper stays(24) are integrally formed with the back beam main body(20) at opposite ends thereof.

The steel back beam 122 is fixed to the inside of the 121, and the iron brackets 220 and 221 are installed on both upper and lower sides of the iron back beam 122, and at both ends of the back beam 122 at the same time. The bumper stay 222 is installed.

그러나 상기한 리어 범퍼는 여러개의 단위 부품으로 제조한 후 조립하여야 하기 때문에 원가가 상승되고 부품관리가 복잡하며, 또한 적어도 3개 재질의 원자재로 되어 있음으로 재생시에 분리가 번잡하고 비용이 많이 드는 문제점이 있는 것이다.However, since the rear bumper has to be manufactured after assembling a plurality of unit parts, the cost is increased, the parts management is complicated, and at least three materials are complicated, and the separation is complicated and expensive at the time of regeneration. Is there.

본 발명은 상기한 문제점을 시정하여, 부품을 단순화하면서 완충기능이 양호하고, 재생이 용이하며, 경량화한 자동차용 리어 범퍼를 제공하는 것을 목적으로 한다.It is an object of the present invention to correct the above problems and to provide a rear bumper for automobiles which has a good cushioning function, easy to reproduce, and light weight while simplifying parts.

상기한 목적을 달성하기 위하여, 본 발명은 합성수지제 범퍼 커버와, 상기 범퍼 커버의 내측 중앙에 배치되고 상하 양측에 브래킷과 양단에 범퍼 스테이를 일체로 형성함과 동시에 백 빔본체를 허니콤으로 형성한 합성수지제 백 빔으로 구성한 것이다.In order to achieve the above object, the present invention is formed of a synthetic resin bumper cover, the inner center of the bumper cover and the back beam main body is formed in the honeycomb at the same time to form a bumper stay on both ends and upper and lower sides integrally It consists of a synthetic back beam.
