Description
본 발명은 자동차용 안전범퍼에 관한 것으로, 더욱 상세하게는 절첩식 구조를 취하는 범퍼내에 충격완화장치를 내설하여 자동차 운행중 발생되는 충돌사고로 부터 운전자를 안전하게 보호할수 있도록 함과 동시에 충돌사고에 따른 차체손상을 최소화하여 안정성 및 내구성을 향상시킬수 있도록 한 자동차용 안전범퍼에 관한 것이다.The present invention relates to a safety bumper for an automobile, and more particularly, by installing a shock-absorbing device in a bumper having a folding structure to protect a driver from a collision accident occurring while driving a vehicle and at the same time a vehicle body according to a collision accident. The present invention relates to a safety bumper for a vehicle that can minimize damage and improve stability and durability.
자동차 운행중 발생되는 교통사고는 통계상 약 75%이상이 차량 대 차량의 충돌 사고로서, 그 중 대부분이 정면 충돌상황 보다는 부분충돌(off set)상황에 의한 사고가 주류를 이루고 있는 실정인 바, 이러한 차량충돌사고로 부터 운전자를 안전하게 보호하고 차량의 손상을 예방하기 위하여 통상 모든 자동차는 자체의 전, 후방면에 완충작용을 행하는 범퍼를 장착하게 되는 것이다.More than 75% of traffic accidents occur during the operation of automobiles, and most of them are car-to-vehicle collisions, most of which are mainly caused by off-set situations rather than frontal collisions. In order to protect the driver from a collision accident and to prevent damage to the vehicle, all vehicles usually have a bumper that cushions the front and rear surfaces of the vehicle.
이에, 상기한 바와같은 차량의 충돌사고로 부터 운전자와 차량을 보호하기 위해 사용되고 있는 일반적인 차량용 범퍼는 도 1로 도시된 바와같은 구성으로서, 신축성 재질로 이루어진 범퍼본체(10) 내부에 일정한 공간부를 형성하고, 이 공간부에 완충부재(20) 내지 완충프레임(30)을 내설되도록하여 이를 차체의 전,후 방면에 장착시키므로서 그 이용관계를 갖게 하는 것이었다.Thus, a general vehicle bumper being used to protect the driver and the vehicle from the collision of the vehicle as described above, as shown in Figure 1, a constant space portion formed inside the bumper body 10 made of an elastic material In addition, the buffer member 20 to the buffer frame 30 are built in this space portion, and this is to be mounted on the front and rear sides of the vehicle body to have a use relationship.
하지만, 전술한 바와같은 구성을 갖는 종래의 차량범퍼는 단순히 신축작용을 행하는 펌퍼의 재질특성만을 이용한 것으로, 고속주행중 차량의 충돌사고가 발생할경우, 그 충격을 효과적으로 흡수하지 못한체 그대로 파손되며 운전자와 차량보호기능을 전혀 수행치 못하게 되는 내구성 저하의 문제점을 주는 것이었을 뿐만 아니라, 범퍼본체 내부로 내설된 완충부재 내지 완충프레임 또한 미약한 신축 복원력 및 충격 흡수력에 의해 운전자와 차량보호 역할을 충분히 기대할수 없는 상당한 구조적 결함의 문제점을 갖게 하는 것이었다.However, the conventional vehicle bumper having the configuration as described above simply uses the material characteristics of the pump that performs the expansion and contraction action. When a collision accident of the vehicle occurs during a high-speed driving, it is damaged as it is not absorbed effectively and the driver and the vehicle are damaged. Not only did it provide a problem of deterioration in durability, which prevents the protective function from being performed at all, and the buffer member or buffer frame built into the bumper body also has a weak elastic restoring force and shock absorbing ability, so that the driver and vehicle protection role cannot be sufficiently expected. It was a problem of considerable structural defects.
한편, 또 다르게 상기한 종래의 차량범퍼는 차량의 부분충돌(off set)시 충돌부위의 충격 집중현상으로 인해 경미한 접촉사고에 의해서도 쉽게 뒤틀림 변형되거나 파손되어 차량의 손상을 상대적으로 증폭되게 하는 문제점을 주는 것이었을 뿐만 아니라, 상기 차량 접촉부위로 집중된 차체의 충격을 외부로 원할하게 분산시키지 못한체 그대로 운전자에게 전달시키게 되므로 상해의 정도 또한 더욱 증폭되게하는 등, 상당한 안전성의 문제점을 항상 상존시키는 것이었다.On the other hand, the above-mentioned conventional vehicle bumper has a problem that it is easily twisted, deformed or broken by a slight contact accident due to the impact concentration phenomenon of the collision site during the partial collision (off set) of the vehicle to relatively amplify the damage of the vehicle. Not only was it to give, but also to deliver the impact of the car body concentrated in the vehicle contact area to the driver as it was not smoothly distributed to the outside, so that the degree of injury is further amplified, such a constant safety problem always existed.
따라서, 본 발명은 종래 차량용 범퍼의 제반적인 문제점을 해결하고자 창안된 것으로;Accordingly, the present invention has been made to solve the general problems of the conventional vehicle bumper;
본 발명의 목적은 절첩기능을 행하는 범퍼프레임을 형성하고, 그 내부로 충격완화장치를 내설되도록하여 차량 고속주행에 의한 대형 충돌사고로 부터 경미한접촉사고에 이르기 까지 효과적인 완충작용을 행하도록 함과 동시에 이와같은 효과적인 완충작용으로서 차량의 충돌사고시 운전자의 상해 정도 및 차량의 손상 정도를 대폭 경감되도록 하여 내구성과 안전성을 극히 향상되도록 자동차용 안전범퍼를 제공함에 있는 것이다.An object of the present invention is to form a bumper frame to perform a folding function, and to provide a shock-absorbing device therein to perform an effective buffering action from a large collision accident caused by a high-speed vehicle to a slight contact accident at the same time As an effective shock absorbing effect, it is to provide a safety bumper for a vehicle so as to greatly reduce the degree of injury of the driver and the degree of damage to the vehicle in the event of a crash of the vehicle, thereby greatly improving durability and safety.
한편, 본 발명의 또 다른 목적으로는 관절을이루는 다수개의 링크부재 연결구조로서 차량충돌시 충돌부위에 탄력적인 유동성을 부여되도록 하여, 범퍼의 파손을 최소화 되도록 하고, 특히 차량 범퍼의 부분충돌(off set)시 유동성을 갖는 범퍼의 경사각 발생으로 차량의 충돌 충격을 회피되게하므로서 차량사고로 부터 운전자를 효과적으로 보호할수 있도록 한 자동차용 안전범퍼를 제공함에 있는 것이다On the other hand, another object of the present invention is to provide a plurality of link member connection structure to form a joint to provide elastic fluidity to the impact site during the collision, to minimize the breakage of the bumper, in particular partial collision (off) of the vehicle bumper It is to provide a safety bumper for a vehicle that can effectively protect the driver from a vehicle accident while avoiding a crash impact of the vehicle by generating an inclination angle of a flexible bumper during set).

A shock absorbing portion having a honeycomb-type air bag and a shock absorbing portion formed of an air cylinder are formed on the rear side thereof. After forming the drive unit for controlling the air cylinder and the air bag by connecting an air circulation line, it is achieved by causing the bumper frame to be coupled with the chassis frame provided with a transfer guide projection to perform the contraction and expansion of the optional bumper. .
