Abstract

The air is pressed inside the bumper employing the synthetic resin tube body, and is adhered in a high frequency in a certain length(W) using a hot plate(6). By cutting the adhered part with a cutter(7), an air pack(3) of a certain size containing an air chamber(8) is manufactured. In each dent of the buffer panel which will be inserted between the car impact beam(5) and the bumper main body(4), an air pack is embedded. When an impact is applied from the outside to the main body bumper(4), the shock is absorbed by the air pressure of the buffer panel air pack. Consequently the impact energy is eliminated, the bumper main body is returned to the original shape by the smooth restoring elasticity, preventing the maximum damage of a vehicle body and the loss of a person.

본 발명은 자동차용 범퍼를 충격에 대한 완충효과가 매우 우수하도록 개선한 것이다.The present invention is to improve the bumper for automobile to have a very good shock absorbing effect.

종래 일반화된 자동차용 범퍼는 철판으로 구성된 임팩트빔과 범퍼본체 사이에 발포성 합성수지충진재로 이루어진 완충팩을 내장한 구조였던 바, 이와 같은 소재를 내장한 범퍼는 장애물에 범포본체가 충돌할시 비교적 완충효과가 저조하여 차량의 파손 및 인명사고에 대하여 안전성이 미흡한 편이었다.Conventionally generalized automobile bumpers have a structure in which a buffer pack made of a foamable synthetic resin filler is embedded between an impact beam made of steel plates and a bumper body, and a bumper having such a material has a relatively cushioning effect when a bumper body collides with an obstacle. Due to the low speed, safety was inadequate for vehicle damage and casualties.

본 발명은 발포성스펀지 등 일반적인 완충재의 내장구조와는 달리 내인장 강도와 파열강도가 대단히 우수한 고밀도 합성수지시이트를 이용한 공기 내장식 에어팩을 내장한 범퍼의 구조로 개선함으로서 충격부하에 대한 완충효과가 대단히 양호하도록 자동차용 범퍼의 구조를 발전시킨 것으로서, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention, unlike the built-in structure of the general cushioning material, such as foam foam sponge, by improving the structure of the bumper with the built-in air-packing air pack using a high-density synthetic resin sheet excellent in tensile strength and burst strength is very good buffering effect against impact load As to develop the structure of the bumper for cars to be described in detail by the accompanying drawings as follows.

제 1 도는 본 발명의 분해사시도로서, 금속판으로 이루어진 임팩트빔(5)의 전면에 범퍼본체(4)를 결합한 일반적인 자동차용 완충범퍼에 있어서, 상기 범퍼본체(4)와 임팩트빔(5) 사이에는 합성수지제로 된 완충판넬(1)을 내장하되, 상기 완충판넬(1)의 전면에 요입실(2)을 다수개 요설하여 그 내부에는 인장강도가 높은 합성수지 시이트 관체를 소재로 한 에어팩(3)을 내장하여서 된 것이다.1 is an exploded perspective view of the present invention, in a general bumper for automobiles in which the bumper body 4 is coupled to the front surface of the impact beam 5 made of a metal plate, between the bumper body 4 and the impact beam 5. Built-in buffer panel (1) made of a synthetic resin, and a plurality of inlet chamber (2) in the front of the buffer panel (1), the inside of the air pack (3) made of a material of a synthetic resin sheet of high tensile strength It was built.

상기 구성중 에어팩(3)은 제 3 도와 같이 인장강도가 우수한 합성수지 관체를 이용하여 내부에 공기를 압입(壓入)한 다음 전열판(6)을 이용하여 일정한 길이(W)로 고주파 접착하고, 상기 접착된 부위를 커터(7)로 절단함으로서 에어실(8)을 가진 일정한 규격의 에어팩(3)이 제조된다.The air pack 3 of the above configuration is press-fitted into the air by using a synthetic resin tube having excellent tensile strength as shown in the third degree, and then bonded at a high frequency using a heat transfer plate 6 to a predetermined length (W), and By cutting the bonded portion with the cutter 7, an air pack 3 of constant size with an air chamber 8 is produced.

그리고 에어팩(3)의 구조는 제 3 도와 같이 하나의 합성수지 관체를 고주파 접착하여 형성할 수도 있지만, 제 4 도와 같이 합성수지 관체 속에 또 다른 작은 규격의 소관체(3')를 매입하여 2중의 에어팩 구조로 형성할 수도 있다.And the structure of the air pack (3) may be formed by high-frequency bonding one synthetic resin tube as shown in the third diagram, but a double air pack structure by embedding another small size of the small pipe (3 ') in the synthetic resin tube as shown in the fourth diagram It can also be formed.

이상과 같이 구성된 본 발명은 제 2 도와 같이 자동차용 임팩트빔(5)과 범퍼본체(4) 사이에 삽설내장하는 완충판넬(1)에 요입실(2)을 구성하고, 상기 요입실(2)마다 일정규격의 에어팩(3)을 내장하여 범퍼심재를 구성하는 것으로, 이와 같이 구성된 본 발명은 외부로부터 충격부하가 범퍼본체(4)에 전달되었을 시에 완충판넬(1)에 내장된 에어팩(3) 자체가 갖는 공기압에 의해서 당해 충격을 흡수완충시키고 충격에너지가 제거되면 공기압의 원활한 복원탄성에 의하여 범퍼본체(4)는 원래의 형태로 환원되어 최대한 차체의 손상과 인명피해의 손실을 방지할 수 있게 되는 것이다.According to the present invention configured as described above, the urine chamber 2 is formed in the buffer panel 1 inserted between the impact beam 5 for automobiles and the bumper body 4 as in the second diagram. The bumper core material is constructed by incorporating the air pack 3 of a predetermined standard every time. The present invention thus constructed provides an air pack 3 embedded in the shock absorbing panel 1 when an impact load is transmitted from the outside to the bumper body 4. ) When the shock is absorbed and buffered by the air pressure itself and the impact energy is removed, the bumper body 4 is reduced to its original form by the smooth restoration elasticity of the air pressure to prevent damage to the vehicle body and loss of human life. Will be.

그리고 본 발명의 에어팩(3)의 구성을 제 4, 5 도와 같이 2중 복합구조, 또는 3중 복합구조로 형성하여 내장하면 내충격성과 완충성을 일층 강화시킬 수 있는 것이다.In addition, when the air pack 3 of the present invention is formed by forming a double complex structure or a triple complex structure, as in the fourth and fifth degrees, the impact resistance and the buffer resistance can be further enhanced.

또한 완충판넬(1)의 요입실(2)에 에어팩(3)을 수납할시 제 6 도와 같이 격간으로 에어팩 대신 일반 발포성 수지완충팩(9)을 교대로 삽설하여 완충효과와 강약조절 기능을 갖도록 변경실시할 수도 있다.In addition, when storing the air pack (3) in the inlet chamber (2) of the buffer panel (1) alternately insert the ordinary foam buffer pack (9) instead of the air pack at intervals as shown in the sixth degree to have a buffer effect and strength control function. You can also make changes.

본 발명은 이상과 같이 자동차용 범퍼에 압축공기가 내장된 다수의 에어팩(3)을 내장한데 특징이 있는 바, 종래의 발포성 스펀지체로 구성된 완충소재에 비하여 충격에 대한 완충효과가 뛰어나 각종 차량 접촉사고의 따른 차량의 손상을 최대한 방지할 수 있고, 또한 교통사고 발생시 많은 인명피해를 줄일 수 있는 것으로 그 사용 가치가 매우 현저한 발명이다.The present invention is characterized in that a plurality of air packs (3) in which the compressed air is built into the bumper for automobiles as described above. Compared to the cushioning material composed of a conventional foamed sponge, the shock absorbing effect against shock is excellent, and various vehicle contact accidents are included. It is possible to prevent the damage of the vehicle as much as possible, and also to reduce many casualties in the event of a traffic accident, its use is very significant invention.

이하의 부수되는 특허청구의 범위에서 본 발명이 보호받고져 하는 사항이 기재될 것이지만, 일부 구성물을 단순히 등가물로 치환하는 등의 당해업계에 숙달된 자에 의하여 용이하게 실시할 수 있는 변경 실시예 역시 본 발명에서 해결코져한 기본적인 기술을 일탈치 않는한 본 발명과 동일한 기술이라 할 것이다.In the following appended claims, matters to be protected by the present invention will be described, but examples of modifications that can be easily implemented by those skilled in the art, such as simply replacing some of the components with equivalents, are also described. The same technology as the present invention will be described without departing from the basic technology solved by the present invention.
