Abstract

PURPOSE: Front body structure for a truck is provided to shut off noise efficiently, and to improve safety of a passenger at a collision by forming a closed section with a dash panel. CONSTITUTION: A couple of front pillars(10) are arranged at both sides of a vehicle body, and the closed section is formed with combining an inner panel(11) and an outer panel(12) with the front pillars. An end of a front panel(30) is combined with a front assembling part of the inner panel and the outer panel. Both ends of a dash panel(20) are combined with the inner panel of the front panel, and the dash panel is arranged in the rear part of the front panel. Noise is shut off efficiently with the front panel and the dash panel. The front panel is supported by the dash panel in applying external force to the front panel at a head-on collision, and the front pillar is prevented from being moved into the vehicle. Safety of a passenger is improved with arranging the dash panel in the rear part of the front panel.

Description

화물차량의 전방 차체구조Front body structure of freight vehicle

본 발명은 화물차량의 전방 차체구조에 관한 것으로, 차실내로의 외부소음이효과적으로 차단하고, 전방 추돌사고시 탑승자의 안정성이 향상되도록 하는 화물차량의 전방 차체구조에 관한 것이다.The present invention relates to a front body structure of a freight vehicle, and relates to a front body structure of a freight vehicle to effectively block external noise into the cabin and to improve the stability of the occupant in the event of a front collision.

제1도를 참조하여 종래 화물차량의 전방 차체구조를 설명해 보면, 한 쌍의 프론트필라(10)가 차체 양측에 서로 상응하게 각각 배치되고, 이들 프론트필라(10)는 각각 내측패널(11)과 외측패널(12)이 맞대어져 결합되어 폐단면을 이루는 구조이며, 내측패널(11)과 외측패널(12)의 전방쪽 결합부에 프론트패널(30)의 선단이 결합되어진 구조를 이룬다.Referring to FIG. 1, a front body structure of a conventional freight vehicle is described. A pair of front pillars 10 are disposed on both sides of the vehicle body, respectively, and the front pillars 10 are respectively provided with the inner panel 11 and the front pillars 10. The outer panel 12 is coupled to each other to form a closed cross section, and the front panel 30 is coupled to the front coupling portion of the inner panel 11 and the outer panel 12 to form a structure combined.

따라서, 전방 추돌사고시 외력이 프론트패널(30)에 가해지게 되면, 프론트패 널(30)이 뒷쪽으로 밀리게 되는데, 이때 프론트패널(30)의 양쪽 선단이 프론트필라(10)에 의해 지지되어 프론트패널(30)의 뒷쪽으로의 밀림이 억제된다.Therefore, when an external force is applied to the front panel 30 during the front collision accident, the front panel 30 is pushed to the rear side, and both front ends of the front panel 30 are supported by the front pillars 10 so that the front panel 30 is pushed forward. The rolling back of the panel 30 is suppressed.

그러나, 상기 종래 기술에 따르면, 한 쌍의 프론트필라(10) 전방에 단순히 하나의 프론트패널(30)만이 설치되어진 구조이므로, 외부로부터의 소음이 만족스럽게 차단되지 못하는 한편, 전방 추돌사고시 프론트패널(30)이 외력에 의해 쉽게 후방으로, 즉 차실내로 침입되므로, 탑승자의 안전이 크게 위협되는 문제가 발생되었다.However, according to the prior art, since only one front panel 30 is installed in front of the pair of front pillars 10, noise from the outside cannot be satisfactorily blocked, and at the time of a front collision accident, the front panel ( Since 30) easily penetrates to the rear by the external force, i.e., into the interior of the vehicle, there is a problem that the safety of the occupants is greatly threatened.

또한, 측방 추돌사고시 프론트사이드도어(도시안됨)에 외력이 가해지게 되면, 프론트사이드도어가 힌지고정되어진 프론트필라(10)로 외력이 전달되는데, 종래 기술에 따르면 프론트필라(10)가 프론트패널(30)에 의해서만 지지되는 구조이므로, 프론트필라(10)가 횡방향으로 쉽게 굴곡되면서 프론트사이드도어가 차실내로 쉽게 침입하게 되어, 탑승자의 안전이 크게 위협되는 문제가 발생되었다.In addition, when an external force is applied to the front side door (not shown) during the side collision accident, the external force is transmitted to the front pillar 10 in which the front side door is hinged and fixed. According to the related art, the front pillar 10 is a front panel ( Since the structure is supported only by 30), the front pillar 10 is easily bent in the lateral direction and the front side door easily penetrates into the interior of the vehicle, causing a problem that the safety of the occupants is greatly threatened.

이에 본 발명은 상기와 같은 문제를 해결하기 위하여 발명된 것으로, 차실내로의 외부소음이 효과적으로 차단괴고, 전방 추돌사고시 탑승자의 안정성이 향상되도록 하는 화물차량의 전방 차체구조를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to solve the above problems, the object of the present invention is to provide a front vehicle body structure of a cargo vehicle to effectively block the outside noise into the vehicle interior, and to improve the stability of the occupant in the event of a front collision. .

상기와 같은 목적을 달성하기 위한 본 발명은, 한 쌍의 프론트필라가 차체 양측에 서로 상응하게 각각 배치되고, 이들 프론트필라는 각각 내측패널과 외측패널이 맞대어져 결합되어 폐단면을 이루는 구조이며, 내측패널과 외측패널의 전방쪽 결합부에 프론트패널의 선단이 결합되어진 화물차량의 전방 차체구조에 있어서, 상기 서로 마주보는 프론트필라의 내측패널에 대쉬패널의 양쪽 선단이 각각 결합되어, 대쉬패널이 프론트패널보다 후방에 배치되어진 것을 특징으로 하는 구조로 되어 있다.According to the present invention for achieving the above object, a pair of front pillars are respectively arranged on both sides of the vehicle body, these front pillars are the inner panel and the outer panel are coupled to each other to form a closed cross-section, In the front body structure of a freight vehicle in which the front end of the front panel is coupled to the front engaging portion of the inner panel and the outer panel, both ends of the dash panel are coupled to the inner panel of the front pillar facing each other, so that the dash panel The structure is characterized by being disposed behind the front panel.

이하 본 발명을 첨부된 예시도면에 의거하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 발명에 따른 화물차량의 전방 차체구조를 개략적으로 도시한 평단면도인 바, 종래 기술을 도시한 제1도와 동일한 부위에는 동일한 인출부호를 붙이면서 그 설명은 생략한다.FIG. 2 is a planar cross-sectional view schematically showing a front vehicle body structure of a freight vehicle according to the present invention, and the description thereof is omitted while attaching the same withdrawal code to the same portion as the first view of the prior art.

제2도에 의하면 본 발명에 따른 화물차량의 전방 차체구조는, 한 쌍의 프론트 필라(10)가 차체 양측에 서로 상응하게 각각 배치되고, 이들 프론트필라(10)는 각각 내측패널(11)과 외측패널(12)이 맞대어져 결합되어 폐단면을 이루는 구조이며, 내측패널(11)과 외측패널(12)의 전방쪽 결합부에 프론트패널(30)의 선단이 각각 결합되면서, 서로 마주보는 프론트필라(10)의 내측패널(11)에 대쉬패널(20)의 양쪽 선단이 각각 결합되어, 대쉬패널(20)이 프론트패널(30)보다 후방에 배치되어진 구조로 되어 있다.According to FIG. 2, in the front body structure of the freight vehicle according to the present invention, a pair of front pillars 10 are respectively disposed on both sides of the vehicle body, and these front pillars 10 are respectively provided with an inner panel 11 and an inner panel 11. The outer panel 12 is coupled to each other to form a closed cross-section, the front end of the front panel 30 is coupled to the front coupling portion of the inner panel 11 and the outer panel 12, respectively, the front facing each other Both ends of the dash panel 20 are respectively coupled to the inner panel 11 of the pillar 10 so that the dash panel 20 is arranged behind the front panel 30.

따라서, 외부로부터의 실외소음이 프론트패널(30)에 의해 1차적으로 차단된 후, 대쉬패널(20)에 의해 2차적으로 차단되므로, 차실내로의 실외소음전달이 효과적으로 차단되는 한편, 전방 추돌사고시 프론트패널(30)에 외력이 가해지게 되면, 대쉬패널(20)이 후방으로 밀리는 프론트패널(30)을 지지하게 되므로, 프론트필라(10)의 차실내로의 침입이 억제된다.Therefore, since outdoor noise from the outside is primarily blocked by the front panel 30 and then secondly blocked by the dash panel 20, outdoor noise transmission to the interior of the vehicle is effectively blocked, while the front bumper When an external force is applied to the notification front panel 30, the dash panel 20 supports the front panel 30 that is pushed backward, thereby preventing the front pillar 10 from entering the vehicle interior.

또한, 측방 추돌사고시 프론트사이드도어(도시안됨)에 외력이 가해지게 되면, 프론트사이드도어가 힌지고정되어진 프론트필라(10)로 외력이 전달되는데, 본 발명에 따르면 프론트필라(10)가 프론트패널(30)과 대쉬패널(20)에 의해 2중으로 지지되므로, 프론트필라(10)의 횡방향으로의 굴곡이 억제되어, 프론트사이드도어의 차실내로의 침입이 억제된다.In addition, when an external force is applied to the front side door (not shown) during the side collision accident, the external force is transmitted to the front pillar 10 to which the front side door is hinged, and according to the present invention, the front pillar 10 is a front panel ( 30) and the dash panel 20 are supported in duplicate, so that curvature of the front pillar 10 in the lateral direction is suppressed, and penetration of the front side door into the vehicle interior is suppressed.

이상 상기한 바와 같은 본 발명에 따르면, 서로 마주보는 프론트필라의 내측패널에 대쉬패널의 양쪽 선단이 결합되어, 대쉬패널이 프론트패널의 후방위치에 배치되어진 구조로 되어, 외부소음이 차실내로 전달되는 것이 효과적으로 차단되고, 전방 추돌사고, 또는 측방 추돌사고시 탑승자의 안전성이 크게 향상되는 효과가 있다.According to the present invention as described above, both ends of the dash panel is coupled to the inner panel of the front pillar facing each other, so that the dash panel is arranged in the rear position of the front panel, the external noise is transmitted to the interior of the vehicle Being effectively blocked, there is an effect that the safety of the occupant in the front collision or side collision accident is greatly improved.
