Description
본 발명은 범퍼의 충격에너지 흡수장치에 관한 것으로, 보다 상세하게는 승용차 범퍼 내의 중앙부에서 충격에너지를 흡수할 수 있도록 한 범퍼의 충격에너지 흡수장치에 관한 것이다.The present invention relates to an impact energy absorber of a bumper, and more particularly, to an impact energy absorber of a bumper that is capable of absorbing impact energy at a central portion in a passenger car bumper.
일반적으로 자동차의 충돌 사고시 안전을 확보하기 위한 테스트로는 전방충돌과 측면충돌 등이 있으며, 이는 자동차의 안정성을 확보하는 중요한 요소로서 이미 각 나라에서는 이러한 충돌시의 안전치를 법규화하여 수입규제 등의 큰 항목으로 적용하고 있다.In general, tests to ensure safety in the event of a car crash include front and side collisions, which are important factors to secure the stability of the car. It is applied to large items.
이와 같은 이유로 인하여 일반적인 자동차는 외부로부터 충격을 흡수 완화시키는 범퍼(A)를 구비하고 있으며, 상기 범퍼(A)는 차량의 전방으로 가해지는 외부충격에 의해 라디에이터 및 엔진룸 측을 보호하는 전방범퍼와, 후방으로 가해지는 외부충격으로부터의 트렁크를 보호하는 후방범퍼가 있다.For this reason, a typical vehicle includes a bumper A for absorbing and mitigating shock from the outside, and the bumper A includes a front bumper that protects the radiator and the engine room by an external shock applied to the front of the vehicle. There is a rear bumper that protects the trunk from external shocks applied to the rear.
이러한 범퍼(A)는 차량의 가장 바깥쪽을 감싸고 있어 작은 충격이 가해질 경우에는 차체 자체의 손상을 방지하는 역할을 수행함은 물론 인명피해를 최소함과 동시에 차량의 손실을 방지하기 위해 자동차에는 필수적으로 구비되고 있다.Such a bumper (A) surrounds the outermost part of the vehicle, and thus, when a small impact is applied, the bumper (A) serves to prevent damage to the vehicle body itself, and is essential to the vehicle to minimize loss of life and prevent loss of the vehicle. It is provided.
상기와 같은 범퍼(A)는 차량의 종류에 따라 여러 가지의 형태로 구성되는데, 이러한 차량에 적용되는 범퍼의 일례를 살펴보면 하기와 같다.The bumper A as described above is configured in various forms according to the type of the vehicle, and an example of the bumper applied to the vehicle is as follows.
종래의 범퍼(A)는 커버(미도시)의 내측에 완충작용을 하는 제1 충격흡수부재(1-1)가 부착되고, 이 제1 충격흡수부재(1-1)의 내측으로 범퍼커버와 제1 충격흡수부재(1-1)를 지지하는 제1 보강재(2)(일명 레일이라 함)가 부착되는 형태를 취하는 것이 가장 일반적인 형식이다.Conventional bumper (A) has a first shock absorbing member (1-1) to the inside of the cover (not shown) to the cushioning action is attached, the bumper cover and the inside of the first shock absorbing member (1-1) The most common form is that the first reinforcing member 2 (also called a rail) supporting the first shock absorbing member 1-1 is attached.
이 범퍼는 범퍼커버를 사출성형하고, 제1 충격흡수부재(1-1)를 폴리프로필렌 폼(PP foam)으로 하며, 제1 보강재(2)는 프레스 가공한 것이다.The bumper is injection molded of the bumper cover, the first shock absorbing member 1-1 is made of polypropylene foam (PP foam), and the first reinforcing material 2 is press processed.
하지만, 상기와 같은 종래의 범퍼의 충격에너지 흡수장치는 다음과 같은 문제점이 있었다.However, the conventional impact energy absorber of the bumper as described above has the following problems.
상기한 유형의 범퍼는 대부분 2.5MPH(Mile Per Hour)에 견딜 수 있는 범퍼에 주로 적용되는 것으로, 5MPH에 견디도록 하기 위한 범퍼는 그 충격에너지가 크기 때문에 이를 극복하기 위한 적절한 보강이 필요하다.Most of the above types of bumpers are mainly applied to bumpers capable of withstanding 2.5 MPH (Mile Per Hour), and bumpers to withstand 5 MPH need appropriate reinforcement to overcome them because of their high impact energy.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 미국의 '도로안전을 위한 보험협회'(IIHS: Insurance Institute for Highway Safety) 시험의 상품성을 만족하기 위해 5MPH, 2.5MPH 및 폴테스트(Pole Test)의 저속충돌시 범퍼의 충격에너지 흡수력을 향상시킬 수 있도록 하는 범퍼의 충격에너지 흡수장치을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, 5MPH, 2.5MPH and Pole test (Pole) in order to satisfy the merchandise of the Insurance Institute for Highway Safety (IIHS) test of the United States It is an object of the present invention to provide a bumper shock energy absorbing device that can improve the impact energy absorbing power of a bumper during a low-speed crash.

상기한 목적을 달성하기 위한 본 발명의 형태에 따르면, 상부 내측에는 다수의 격벽으로 인해 요홈이 분할형성되며, 중간부 내측에는 돌출부가 형성되는 제1 충격흡수부재; 상기 제1 충격흡수부재 하부 내측면과 상기 제1 충격흡수부재의 돌출부 하면에 접촉되어 고착되며, 내부가 제2 충격흡수부재로 충진되는 제1 보강재; 상기 제2 충격흡수부재에 접촉되어 고착되는 제2 보강재; 및 상기 제2 보강재의 양단에 돌출형성되며 하부가 지지부재에 의해 지지되는 체결부재로 구성되는 것을 특징으로 하는 범퍼의 충격에너지 흡수장치를 제공한다.According to an aspect of the present invention for achieving the above object, a first impact absorbing member is formed in the upper groove is divided into the groove due to the plurality of partitions, the inner portion of the middle portion is formed with a protrusion; A first reinforcing member which is brought into contact with and fixed to a lower inner surface of the first shock absorbing member and a lower surface of the protrusion of the first shock absorbing member and is filled with a second shock absorbing member; A second reinforcing member fixed to and in contact with the second shock absorbing member; And a fastening member protruding from both ends of the second reinforcing material and having a lower portion supported by the support member.
이하, 첨부된 도면을 참조하여 본 발명에 따른 범퍼의 충격에너지 흡수장치에 관한 바람직한 실시예를 설명하면 다음과 같다.도 2는 본 발명에 따른 범퍼의 충격에너지 흡수장치의 단면 사시도이다.Hereinafter, a preferred embodiment of an impact energy absorber of a bumper according to the present invention will be described with reference to the accompanying drawings. FIG. 2 is a cross-sectional perspective view of an impact energy absorber of a bumper according to the present invention.
도시된 바와 같이, 최외측에 형성된 'ㄱ'형상의 제1 충격흡수부재(1-1)는 상부 내측이 직사각형의 다수의 요홈(1-3)이 형성되어 격벽(1-2)에 의해 분할된다.As shown, the first shock absorbing member 1-1 having the 'a' shape formed at the outermost side is divided into partitions 1-2 by forming a plurality of grooves 1-3 having a rectangular upper side. do.
상기 제1 충격흡수부재(1-1)의 내측 중간부에는 돌출부(1-4)가 형성되며 이 돌출부(1-4)의 하부면과 하부 내측면 사이에는 단면이 'U'형상의 제1 보강재(2)가 면접촉되어 고착된다.A protruding portion 1-4 is formed at an inner middle portion of the first shock absorbing member 1-1, and a cross section is formed in a 'U' shape between the lower surface and the lower inner surface of the protruding portion 1-4. The reinforcing material 2 is fixed in surface contact.
상기 제1 보강재(2) 내부에는 제2 충격흡수부재(3)가 충진되어 있으며 이 제 2 충격흡수부재(3)의 외면에는 중간부가 내측으로 만곡된 'W'형상의 제2 보강재(4)가 고착된다.The second impact absorbing member 3 is filled in the first reinforcing member 2, and the second reinforcing member 4 having a 'W' shape having an intermediate portion curved inward on an outer surface of the second shock absorbing member 3. Is fixed.
상기 제2 보강재(4)의 양측단에는 지지부재(5)가 개재된 후 돌출형성된 체결부재(6)가 고설된다.At both ends of the second reinforcing material 4, the supporting member 5 is interposed, and the fastening member 6 protrudingly formed is installed.
본 발명은 상기와 같은 구성에 따라, 범퍼의 제1 충격흡수부재(1-1)에 2.5MPH 이하의 저속충돌에 따른 충격이 가해지면 제1 충격흡수부재(1-1)와 이에 연결된 제1 보강재(2)에 의해 상기 충격이 흡수된다.According to the configuration as described above, the first shock absorbing member (1-1) and the first connected to the first shock absorbing member (1-1) when the impact is applied to the first shock absorbing member (1-1) of the bumper due to the low-speed impact of 2.5 MPH or less The impact is absorbed by the reinforcing material (2).
그러나 2.5MPH 이상의 저속충돌에 따른 충격이 가해지면 상기 제1 보강재(2) 내부에 충진된 제2 충격흡수부재(3)에 충격이 전달되며 이후 잔류된 충격은 제2 보강재(4)를 거치며 완전히 흡수된다.However, when an impact due to a low speed collision of 2.5 MPH or more is applied, an impact is transmitted to the second shock absorbing member 3 filled in the first reinforcing member 2, and the remaining impact passes through the second reinforcing member 4 completely. Is absorbed.
이상에서 상세히 설명한 바와 같이, 본 발명은 범퍼의 제2 충격흡수부재로부터의 잔류 충격흡수력을 제2 보강재에 의해 완충하여 IIHS의 상품성 평가시험인 5MPH, 2.5MPH 및 폴테스트(Pole Test)의 강도를 극복할 수 있는 효과를 제공한다.As described in detail above, the present invention buffers the residual shock absorbing force from the second shock absorbing member of the bumper by the second reinforcing material to obtain the strength of 5MPH, 2.5MPH and the Pole Test, which is a commercial evaluation test of IIHS. It provides an effect that can be overcome.
