Abstract

An under-riding prevention inner bar structure of a vehicle is provided to protect a driver and the vehicle against a front side collision by installing a support structure on a front end module, which is disposed at a front side of the vehicle to form a vehicle frame. An under-riding prevention inner bar structure of a vehicle comprises an inner bar(300), a connecting part(310), an upper support part(320) and a lower support part(330). The inner bar is coupled at an upper part of a front end module(100), which forms a vehicle frame. The connecting part serves as the center of the inner bar and has a connecting hole(311) through which the connecting part is fixed to the front end module. The upper support part and the lower support part extend from the connecting part and are vertically opened toward a bumper cover.

본 발명은 자동차 언더 라이딩 방지 인너바 구조에 관한 것으로서, 더욱 상 세하게는 자동차의 전방 충돌시 가해지는 충격력에 의해 대형차량의 하부로 자동차의 후드가 진입되지 않도록 마련된 자동차 언더 라이딩 방지 인너바 구조에 관한 것이다.[0001] The present invention relates to an inner bar structure for preventing under-riding of an automobile, and more particularly to an inner bar structure for preventing under-riding of an automobile, which prevents a hood of a car from entering into a lower portion of a large vehicle due to an impact force, .

일반적으로, 승용 자동차의 전방부는 후드에 가려진 엔진룸의 전방에 충돌시 가해지는 충격을 흡수, 분산할 수 있도록 차량의 골격인 차체프레임 부위의 앞쪽으로 차폭을 따라 범퍼가 구비되는 한편, 차량의 주행 중 노면으로부터 가해지는 충격을 흡수 및 완충작용을 하도록 차륜부위에는 엔진룸을 이루는 차체패널에 고정된 현가장치가 장착되어지게 된다.BACKGROUND ART Generally, a front portion of a passenger car is equipped with a bumper in front of an engine room obscured by a hood along a width of a vehicle body in front of a body frame portion, which is a skeleton of a vehicle, so as to absorb and disperse impacts applied during a collision, A suspending device fixed to a vehicle body panel constituting an engine room is mounted on the wheel so as to absorb shocks and buffer shocks from the middle road surface.

그리고, 이와 같은 차량은 통상적으로 엔진 시동 시 차량에 장착된 각종 유압장치들이 작동되면서 압을 생성하여 차체를 들어 올려주기 때문에 엔진의 시동을 킨 상태의 차고가 시동을 끈 상태의 정지 상태의 차고에 비해 보다 상승된 지상고를 갖게 된다.In such a vehicle, since the various hydraulic devices mounted on the vehicle are operated and the pressure is generated to lift the vehicle body when the engine is started, the garage in a state in which the engine is started is in a stopped garage Compared to the previous year.

그러나, 이와 같은 차량의 지상고는 차량의 제동을 위해 브레이크페달을 밟아 브레이크를 작동시키게 되면 차륜에 장착된 브레이크 어셈블리 쪽으로 유압이 작동하면서 급격한 차속 감속에 따라 주행시 차고가 정지시 차고로 복원되는 현상이 발생되고 이에 따라, 트럭과 같은 대형차의 후방으로 전방부가 충돌하게 되면 적재함 밑으로 후드부위가 밀려 들어가 전방부위가 협착됨은 물론 탑승객의 심각한 신체부상을 초래하는 문제가 있게 된다.However, when such a vehicle ground surface is operated by braking the brake pedal for braking the vehicle, hydraulic pressure acts on the brake assembly mounted on the wheel, resulting in a phenomenon that the garage is restored to the garage when the vehicle is stopped As a result, when the front portion collides with the rear portion of a large vehicle such as a truck, the hood portion is pushed under the loading box, causing the forward portion to be stuck, resulting in serious injury to the passenger.

따라서, 상기와 같은 문제점을 해결하려 특허번호 10-2005-0025422, 10-2002-0080879와 같이 차량의 전방 충돌시 가해지는 충격력에 의해 차량의 지상고를 주행중일 때 이상의 높이로 상승시켜 대형차량의 하부로 진입되는 것을 방지하려 하였으나, 양산성 미흡 및 원가 상승이 과다하게 발생되었고, 고가의 유압장치의 필요로 인해 양산성이 미흡한 문제점이 있었다.Therefore, in order to solve the above-mentioned problem, when the ground level of the vehicle is raised to a level equal to or higher than the level when the vehicle is running by the impact force applied at the time of frontal collision of the vehicle as shown in Patent Numbers 10-2005-0025422 and 10-2002-0080879, However, there was a problem that the mass productivity was insufficient and the cost increase was excessive, and the mass productivity was insufficient due to the necessity of the expensive hydraulic device.

또한, 특허번호 10-1998-0060921과 같이 차량의 전방 충돌시 앞차의 급제동에 따라 뒷차의 앞부분이 앞차의 후방으로 깔리는 것을 방지하는 충돌시 승객 보호용 보조범퍼에 관한 것으로 스프링 압축에 의한 후드를 상승시켜 차고를 높이는 장치이나, 이 또한 상기한 문제점과 동일하게 원가상승의 과다발생과 양산성이 미흡한 문제점이 있었다. The present invention relates to an auxiliary bumper for protecting passengers in the event of a collision, which prevents the front part of the rear vehicle from being laid rearward of the front vehicle in accordance with the sudden braking of the front vehicle in the frontal collision of the vehicle as in Patent No. 10-1998-0060921, There is a problem that the increase in cost and the mass productivity are insufficient as in the above-mentioned problems.

본 발명은 상기와 같은 문제점을 해결하기 위해 제안된 것으로서, 자동차의 전방에 마련되어 자동차의 프레임을 이루는 프론트 엔드 모듈에 보강구조를 마련하여 차량 전방충돌에 따른 충격에서 차량을 보호할 수 있도록 자동차 언더 라이딩 방지 구조를 마련하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above problems, and it is an object of the present invention to provide a front end module, which is provided in front of a vehicle, And to provide a preventive structure.

상기의 목적을 달성하기 위한 본 발명에 따른 자동차 언더 라이딩 방지 인너바 구조는, 자동차의 차체 프레임을 이루는 프론트 엔드 모듈과 이 프론트 엔드 모듈 상부에 체결되는 인너바와, 상기 인너바의 중심을 이루며 프론트 엔드 모듈에 고정될 수 있도록 체결공이 형성된 체결부와, 상기 체결부를 중심으로 연장되어 전방의 범퍼 커버를 향해 상/하 외측 방향으로 벌어지도록 형성된 상부 지지부 및 하부 지지부를 포함하여 구성된다.According to an aspect of the present invention, there is provided an inner bar structure for preventing under-riding of an automobile, including a front end module constituting a body frame of an automobile, an inner bar fastened to an upper portion of the front end module, And an upper support portion and a lower support portion which are formed to extend in the upward / downward outward direction toward the front bumper cover.

이하에서, 본 발명에 따른 자동차 언더 라이딩 방지 인너바 구조의 구성 및 그에 따른 실시예를 첨부된 도면을 참조로 더욱 상세히 설명한다.Hereinafter, the structure of the underbar-riding inner bar structure according to the present invention and the embodiments thereof will be described in more detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 자동차 언더 라이딩 방지 인너바 구조의 구조를 도시한 도면이고, 도 3은 본 발명에 따른 자동차 언더 라이딩 방지 인너바 구조의 설치 상태를 도시한 도면이다.FIG. 2 is a view showing a structure of an inner bar preventing inner bar structure according to the present invention, and FIG. 3 is a view showing an installed state of an inner bar preventing inner bar according to the present invention.

자동차의 전방 차체 프레임을 이룰 수 있도록 프론트 엔드 모듈(100)이 마련되고 이 프론트 엔드 모듈(100) 상부에 체결될 수 있도록 인너바(300)가 마련된다.A front end module 100 is provided so as to form a front body frame of an automobile and an inner bar 300 is provided so as to be fastened on the front end module 100. [

상기 인너바(300)는 내열성이 좋고 투명성이 높은 합성수지인 폴리카보네이트와 결정(結晶)성 엔지니어링플라스틱(EP) 중에서도 성형성과 기계특성, 내열성, 내약품성 등이 우수한 폴리 부틸렌테레프 탈레이트의 재질로 만들어진다.The inner bar 300 is made of polybutylene terephthalate having excellent moldability, mechanical properties, heat resistance and chemical resistance among polycarbonate and crystalline engineering plastic (EP) which are high heat resistance and high transparency. Is made.

상기 인너바(300)의 중심을 이루며 상기한 바와 같이 프론트 엔드 모듈(100)에 고정될 수 있도록 체결공(311)이 형성된 체결부(310)가 마련된다.A fastening part 310 having a fastening hole 311 formed at the center of the inner bar 300 so as to be fixed to the front end module 100 is provided.

상기 체결부(310)를 중심으로 연장 형성되어 전방의 마련된 범퍼 커버(200)를 향해 상/하 외측 방향으로 벌어지도록 상부 지지부(320) 및 하부 지지부(330)가 형성된다.The upper support portion 320 and the lower support portion 330 are formed so as to extend around the coupling portion 310 and to extend in the upward / downward direction toward the front bumper cover 200.

또한, 상기 상부 지지부(320) 및 하부 지지부(330)의 단부에는 범퍼 커버(300)에 걸리어 고정될 수 있도록 상부 고정부(321) 및 하부 고정부(331)가 절곡 형성된다.An upper fixing part 321 and a lower fixing part 331 are bent at the ends of the upper supporting part 320 and the lower supporting part 330 so as to be fixed to the bumper cover 300.

또한, 상기 체결공(311)은 체결부(310)의 길이 방향을 따라 2개 이상 형성됨으로 그 체결력이 체결부(310)의 중심과 좌/우 균일하게 제공한다.At least two of the fastening holes 311 are formed along the longitudinal direction of the fastening portion 310 so that the fastening force is uniformly provided to the center of the fastening portion 310 in the left / right direction.

상술한 바와 같이 본 발명에 따른 자동차 언더 라이딩 방지 인너바 구조에 따르면, 자동차의 전방 충돌에 따라 범퍼에 가해진 충격을 프론트 엔드 모듈에 장착된 인너바에 의해 그 충격량을 보상하게 되므로 후드가 압착되면서 전방의 차량 하부로 자동차가 밀려 들어가는 것을 방지하게 되어 운전자 및 탑승자를 보호할 수 있음은 물론 자동차의 충돌 시 후드에 에너지 전달이 미비한 관계로 수리비 저감에 탁월한 효과가 있다.As described above, according to the vehicle under-riding inner bar preventing structure according to the present invention, the impact applied to the bumper due to the front collision of the automobile is compensated for by the inner bar mounted on the front end module, It is possible to protect the driver and the passengers by preventing the vehicle from being pushed into the lower portion of the vehicle, and the energy transfer to the hood is insufficient when the vehicle collides with the vehicle.
