Description

테일게이트 개구부의 강성보강 구조{REINFORCED STRUCTURE OF OPENING FOR TAIL-GATE}Rigid reinforcement structure of the tailgate opening {REINFORCED STRUCTURE OF OPENING FOR TAIL-GATE}

본 발명은 차량의 후방에 위치하는 테일게이트 개구부의 강성보강 구조에 관한 것으로서 더욱 상세하게는 테일게이트 개구부의 세로의(vertical) 변을 형성하는 어퍼멤버와 가로의(horizontal) 변을 형성하는 백패널 사이를 더욱 견고하게 고정시키는 보강재가 장착된 테일게이트 개구부의 강성보강 구조에 관한 것이다.
The present invention relates to a rigid reinforcement structure of a tailgate opening located at a rear of a vehicle, and more particularly, between an upper member forming a vertical side of a tailgate opening and a back panel forming a horizontal side. It relates to a rigid reinforcing structure of the tailgate opening is equipped with a reinforcing material for more securely fixed.

후방에 테일게이트가 장착되는 SUV 또는 MPV 차량은 물품적재가 용이하도록 개구부가 형성되며 상기 테일게이트는 이러한 적재공간의 입구가 되는 개구부를 개폐하도록 구성된다.SUV or MPV vehicles equipped with tailgates at the rear are formed with openings for easy loading, and the tailgates are configured to open and close the openings which are entrances of the loading spaces.

도 1 에 도시된 바와 같이, 테일게이트가 (차체 후방의 윗쪽 또는 차체 후방의 좌우 혹은 상하방향으로 여닫이식으로) 장착되는 차량의 후방 측에는 후방충돌 발생 시 차체를 보호하하도록 범퍼 백빔(미도시)이 장착되도록 백패널이 가로로 배치되고 어퍼멤버가 세로로 배치된 구조를 갖는다.As shown in FIG. 1, a bumper back beam (not shown) is provided on the rear side of the vehicle in which the tail gate is mounted (opening up or down in the left and right or up and down directions of the vehicle body) to protect the vehicle body in the event of a rear collision. The back panel has a structure in which the back panel is disposed horizontally and the upper members are arranged vertically.

상기 어퍼멤버와 백패널은 상기 백패널 끝단 안쪽에 절곡된 판 모양의 벌크헤드(도 6 참조)를 삽입함으로서 용접가능 구역을 확대한 후 상기 용접가능 구역을 용접으로 결합시키는 방식으로 고정되었다.
The upper member and the back panel were fixed by inserting a plate-shaped bulkhead (see FIG. 6) inside the end of the back panel to enlarge the weldable area and then join the weldable area by welding.

하지만, 상기와 같은 종래의 구조에 있어도 어퍼멤버와 백패널을 결합시키기 위한 용접 가능한 구역은 폐단면 형성이나 용접건의 진입문제 등에 기인하여 제한되는 문제점이 있었다. However, even in the conventional structure as described above, the weldable area for joining the upper member and the back panel has a problem that is limited due to the formation of a closed cross-section or an entry problem of the welding gun.

이는 차체 후방의 결합강성을 저하시킬 수 있었으며, 테일게이트의 닫힘 불량을 유발하는 요인이 되었다.This could reduce the coupling stiffness of the rear of the vehicle body, which was a factor causing the closing of the tailgate.

또한, 추가적인 보강부재를 삽입하여 결합강성을 증가시킬 수도 있었으나 이는 부품 수의 증가에 기인하여 중량을 증가시키고 (용접시간의 증가에 따른) 생산속도의 저하를 유발하는 문제점이 있었다.In addition, it was also possible to increase the bonding rigidity by inserting an additional reinforcing member, but this has a problem of increasing the weight due to the increase in the number of parts and causing a decrease in production speed (in accordance with the increase of the welding time).

따라서, 본 발명은 상기와 같은 문제점을 해소하도록 어퍼멤버와 백패널을 더욱 강건하게 결합시킬 수 있는 테일게이트 개구부의 강성보강 구조를 제공하는 것에 주목적이 있다.
Accordingly, the present invention is to provide a rigid reinforcing structure of the tailgate opening that can more robustly combine the upper member and the back panel to solve the above problems.

상기와 같은 목적을 달성하기 위한 본 발명은, 차체 후방에 형성되는 테일게이트 개구부의 강성보강 구조에 있어서, 테일게이트 개구부의 세로변을 형성하고, 하부 끝단에는 가로방향을 향하여 절곡된 모양을 갖는 결합부가 형성된 어퍼멤버;와 테일게이트 개구부의 가로변을 형성도록 상기 결합부와 연결되는 백패널; 및 상기 백패널의 끝단에 장착되어 결합부의 내측에 집입하는 보강재;를 포함하고, 상기 결합부는 전방측을 향하여 형성된 제1결합면과 상기 제1결합면에서 절곡되어 상측을 향하여 형성된 제2결합면 및 상기 제2결합면에서 절곡되어 후방측을 향하여 형성된 제3결합면을 포함하고, 상기 보강재는 패널 모양을 갖되 제1결합면과 제2결합면 및 제3결합면과 맞닿도록 절곡된 것을 특징으로 한다.The present invention for achieving the above object, in the rigid reinforcement structure of the tailgate opening formed in the rear of the vehicle body, to form a longitudinal side of the tailgate opening, the lower end of the coupling having a shape bent toward the transverse direction An upper member formed thereon; and a back panel connected to the coupling part to form a horizontal side of the tailgate opening; And a reinforcing member mounted at an end of the back panel to be inserted into the inner side of the coupling portion, wherein the coupling portion has a first coupling surface formed toward the front side and a second coupling surface bent from the first coupling surface toward the upper side. And a third coupling surface that is bent from the second coupling surface toward the rear side, and the reinforcement has a panel shape and is bent to abut on the first coupling surface, the second coupling surface, and the third coupling surface. It is done.

상기 보강재는 제1결합면과 맞닿게되는 제1절곡면과 제3결합면과 맞닿게되는 제2절곡면을 갖되, 상기 제1절곡면의 끝단이 상측을 향하도록 절곡되어 제2결합면과 맞닿게된다. 더 상세하게는 본 발명에 따른 상기 보강재는 "

Figure 112012081660581-pat00001
" 모양을 이루도록 제2절곡면을 사이에 두고 양측에서 제1절곡면들 각각이 형성된 것을 특징으로 한다.The reinforcement has a first bent surface and a second bent surface which is in contact with the third coupling surface, the first bent surface is in contact with the second coupling surface, the end of the first bent surface is bent upwards and the second coupling surface Abuts. More specifically, the reinforcement according to the present invention is "
Figure 112012081660581-pat00001
"Each of the first bent surface is formed on both sides with the second bent surface to form a shape.

그리고, 상기 양측의 제1절곡면들 사이로 백패널에는 용접건진입홀홀이 타공된다.In addition, a welding key entry hole is drilled in the back panel between the first bent surfaces on both sides.

아울러, 상기 결합부의 외주면에는 제1플랜지가 돌출되고, 상기 백패널의 외주면에는 제2플랜지가 돌출되되, 상기 보강재가 결합부로 진입하면 제1플랜지와 제2플랜지가 맞닿게 된다.
In addition, a first flange protrudes from the outer circumferential surface of the coupling portion, and a second flange protrudes from the outer circumferential surface of the back panel, and the first flange and the second flange come into contact with each other when the reinforcing material enters the coupling portion.

상기와 같은 구성의 본 발명은 어퍼멤버와 백패널이 세 면 이상의 구역에서 용접될 수 있으므로 결합강성을 더욱 향상시킬 수 있다.According to the present invention having the above configuration, the upper member and the back panel may be welded in three or more areas, thereby further improving the bonding rigidity.

또한, 본 발명의 보강재는 종래의 벌크헤드와 비슷한 크기를 갖되 용접가능한 구역을 증가시키고 폐단면의 형성을 방지하여 차량의 중량증가 없이도 결합강성을 더욱 향상시킬 수 있다.In addition, the reinforcement of the present invention has a size similar to that of the conventional bulkhead, but can increase the weldable area and prevent the formation of the closed section to further improve the bonding rigidity without increasing the weight of the vehicle.

그리고, 백패널에는 용접건진입홀이 형성되도록 안쪽의 용접 부위(즉, 제2절곡면이 제3결합면과 용접되는 부위) 근방의 외측에서 제1플랜지와 제2플랜지가 용접으로 결합되어 결합강성이 증가됨에 따라서 안쪽 용접 부위의 크기를 줄일 수 있으므로 종래의 구조 보다 더 작게 형성될 수 있다. 이는 결합강성에 불리한 요인으로 작용하는 홀(용접건관통홀)의 타공을 최소화할 수 있는 효과가 있다.
In addition, the first panel and the second flange are joined together by welding at the outer side of the inner side of the back panel near the welded part (that is, the part where the second bent surface is welded to the third joining surface) to form a welding key entry hole. As this increases, the size of the inner welding portion can be reduced, so that it can be made smaller than the conventional structure. This has the effect of minimizing the perforation of the hole (welding gun through-hole) that acts as a detrimental factor in the bonding rigidity.

도 2 를 참조하면, 본 발명의 어퍼멤버(10)는 차체의 후방에 형성된 테일게이트 개구부의 세로변을 형성하고, 백패널(20)의 일측 끝단과 인접하는 가로방향을 향하여 절곡된 모양을 갖는 결합부(11)가 형성된다. Referring to Figure 2, the upper member 10 of the present invention forms a longitudinal side of the tailgate opening formed in the rear of the vehicle body, the coupling having a shape bent toward the transverse direction adjacent to one end of the back panel 20 The part 11 is formed.

"Is formed in the shape, the first coupling surface (11a) formed toward the front side and the second coupling surface (11b) and the second coupling surface (11b) is bent from the first coupling surface (11a) formed toward the upper side It includes a third coupling surface (11c) (see Fig. 5) is bent in the form toward the rear side.

그리고, 백패널(20)은 테일게이트 개구부의 가로변을 형성하며 끝단 일부가 결합부(11)의 안쪽으로 진입가능하도록 형성된다. In addition, the back panel 20 forms a horizontal side of the tailgate opening and is formed such that a part of the end thereof is accessible into the coupling part 11.

상기 백패널(20)의 내측에는 본 발명에 따른 보강재(30)가 삽입되어 결합부(11)의 내측으로 진입한다. The reinforcing material 30 according to the present invention is inserted into the back panel 20 to enter the coupling portion 11.

상기 보강재(30)는 도 2 에 도시된 바와 같이, 양측에 제1절곡면(31: 31a, 31b)) 두 개가 형성되고 그 사이에 제2절곡면(32)이 형성된 구조를 갖는다. 따라서, 상기 보강재(30)가 결합부(11)의 안쪽으로 진입하게 됐을 때, 상기 제1절곡면(31)은 제1결합면(11a)과 마주하게 되고, 제2절곡면(32)은 제3결합면(11c)과 마주하게 된다. As shown in FIG. 2, the reinforcing material 30 has a structure in which two first bent surfaces 31 (31a and 31b)) are formed on both sides, and a second bent surface 32 is formed therebetween. Therefore, when the reinforcing material 30 enters the inside of the coupling part 11, the first bent surface 31 faces the first coupling surface 11a, and the second bent surface 32 is It faces the third engaging surface (11c).

즉, 본 발명의 바람직한 실시예에 따른 상기 보강재(30)는 "

Figure 112012081660581-pat00003
" 모양을 이루도록 제2절곡면(32)을 사이에 두고 양측에서 제1절곡면들(31a, 31b) 각각이 형성된다. 그리고, 상기 제1절곡면(31)의 상측 끝단(A)은 제2결합면(11b)에 마주할게 될 수 있도록 절곡된 구조(또는 라운딩된 구조)를 갖는다.That is, the reinforcement 30 according to the preferred embodiment of the present invention is "
Figure 112012081660581-pat00003
And each of the first bent surfaces 31a and 31b is formed at both sides with the second bent surface 32 therebetween to form a shape. The upper end A of the first bent surface 31 is It has a structure (or a rounded structure) that is bent so as to face the two engagement surfaces 11b.

따라서, 상기 보강재(30)는 용접작업이 시작되기 전에 백패널(20)을 통해 결합부 내에 진입함으로서, 제1결합면(11a)과 제2결합면(11b) 및 제3결합면(11c) 각각과 마주하게 된다.Therefore, the reinforcing material 30 enters the coupling portion through the back panel 20 before the welding operation is started, so that the first coupling surface 11a, the second coupling surface 11b, and the third coupling surface 11c are respectively. Faced with.

도 4 와 도 5 를 참조하면, 도면 상에 점선으로 표시된 부분은 용접이 이뤄지는 부분을 나타낸다. 백패널(20)에는 용접건이 진입할 수 있는 크기로 용접건진입홀(22)이 타공된다. 4 and 5, portions indicated by dotted lines on the drawings indicate portions to which welding is performed. The welding key entry hole 22 is drilled into the back panel 20 in such a size that the welding gun can enter.

도시된 바와 같이, 본 발명에 따른 보강부(30)의 장착을 통해서 결합부(11)의 제1결합면(11a), 제2결합면(11b) 및 제3결합면(11c) 모두는 백패널(20)에 용접이 이뤄질 수 있다. As shown, all of the first coupling surface 11a, the second coupling surface 11b and the third coupling surface 11c of the coupling portion 11 by mounting the reinforcement portion 30 according to the present invention is a back panel Welding may be made to 20.

아울러, 본 발명의 바람직한 실시예에서 상기 결합부(11)의 외주면에는 제1플랜지(12)가 돌출되고, 상기 백패널(20)의 외주면에는 제2플랜지(21)가 돌출된다. 즉, 상기 보강재(30)가 결합부(11)로 진입하면 제1플랜지(12)와 제2플랜지(21)가 맞닿도록 구성된다. 따라서, 상기 제1플랜지(12)와 제2플랜지(21)를 용접으로 접합하여 결합강성을 추가적으로 증대시킬 수 있다.In addition, in the preferred embodiment of the present invention, the first flange 12 protrudes from the outer circumferential surface of the coupling part 11, and the second flange 21 protrudes from the outer circumferential surface of the back panel 20. That is, when the reinforcing material 30 enters the coupling part 11, the first flange 12 and the second flange 21 contact each other. Therefore, the first flange 12 and the second flange 21 may be joined by welding to further increase the bonding rigidity.

도 6 에 도시된 바와 같이, 종래의 구조에서는 양끝단이 구부려져 백패널 내주면에 끼워지는 벌크헤드를 통해 용접이 이뤄졌으나 (폐단면 발생에 따라) 용접 불가능한 구역이 형성되므로 용접이 가능한 구역은 실질적으로 두 곳으로 밖에 제한되었으며 (용접1로 표기된 부분의 용접을 위해서) 용접건진입홀이 커질 수 밖에 없었다. As shown in FIG. 6, in the conventional structure, the welding is performed through the bulk head which is bent at both ends and fitted to the inner circumferential surface of the back panel. It was limited to only two places (for welding the part marked weld 1) and the welding key entry hole had to be large.

하지만, 본 발명에 따른 구조에서는 (폐단면이 형성된 부분이 없으므로) 용접 가능 구역에 네 곳으로 증가되며, 제1플랜지와 제2플랜지의 추가적인 용접에 따라서 결합강성을 더욱 향상시킬 수 있는 효과가 있다.However, in the structure according to the present invention (because there is no portion having a closed section) is increased to four places in the weldable area, there is an effect that can further improve the bonding rigidity according to the additional welding of the first flange and the second flange. .
