Description

도어 로워 사이드 임팩트 흡수장치Door Lower Side Impact Absorber

본 발명은 도어 로워 사이드에 관한 것으로, 특히 도어 로워 사이드에 충격력이 가해졌을때에 충격력이 실내로 전달되어 탑승자에게 부상을 입히는 것을 방지할 수 있도록 한 도어 로워 사이드 임팩트 흡수장치에 관한 것이다.The present invention relates to a door lower side, and more particularly, to a door lower side impact absorbing device capable of preventing an impact force from being transmitted to an interior when an impact force is applied to the door lower side to prevent injury to a passenger.

일반적으로 종래의 차량에는 도어의 내측 중앙부에 임팩트바를 설치하고, 도어의 외측 하부에는 합성수지재나 금속재의 도어 가니쉬를 부착하여 차량의 외관이 미려할 수 있도록 하였는 데, 이와 같은 종래의 도어 로워 사이드 구조가 도 1 에 도시되어 있다.In general, a conventional vehicle has an impact bar installed at the inner center of the door, and a door garnish made of a synthetic resin or a metal is attached to the lower part of the door to enhance the appearance of the vehicle. 1 is shown.

도 1 에 도시된 바와 같이, 종래의 도어(1)는 하부에 결합공(2)을 형성하고 단부에 플랜지(3)를 형성한 도어 외측 패널(4)과, 하단을 절곡하고 단부에 상기 도어 외측 패널(4)의 플랜지(3)에 결합되는 플랜지(5)를 형성한 도어 내측 패널(6)과, 도어 외측 패널(4)의 결합공(2)에 삽입고정되는 결합돌기(7)를 형성한 도어 가니쉬(8)로 구성한다.As shown in FIG. 1, the conventional door 1 has a door outer panel 4 having a coupling hole 2 formed at a lower portion thereof and a flange 3 formed at an end thereof, and a lower end of the door 1. The door inner panel 6 having the flange 5 coupled to the flange 3 of the outer panel 4 and the engaging projection 7 inserted into the engaging hole 2 of the door outer panel 4 are fastened. It consists of the formed door garnish 8.

이때, 상기 도어 외측 패널(4)과 도어 내측 패널(6)의 결합시에는 공간부(9)가 형성될 수 있도록 일정한 간격을 두고 결합한다.At this time, when the door outer panel 4 and the door inner panel 6 are coupled to each other at regular intervals so that the space 9 is formed.

상기와 같이 구성된 종래의 도어(1)는 도어 외측 패널(4)의 하부에 도어 가니쉬(8)가 설치되어 있으므로, 외관이 미려하여 제품의 가치를 높일 수 있도록 한 것이다.In the conventional door 1 configured as described above, since the door garnish 8 is installed at the lower portion of the door outer panel 4, the exterior is beautiful so as to increase the value of the product.

그러나, 상기한 종래의 도어(1)는 상기 도어 가니쉬(8)를 단순히 차량의 외관이 미려할 수 있도록 한 것이므로, 차량의 측면 충돌시 도어 외측 패널(4)이 충격력을 흡수하지 못하고, 내측으로 절곡되면서 도어 내측 패널(6)에 충격력을 전달하게 되어 충격력에 의해 탑승자가 부상을 당하는 문제가 있었다.However, the above-described conventional door (1) is to simply make the door garnish (8) beautiful appearance, the door outer panel (4) does not absorb the impact force during the side collision of the vehicle, While bending, the impact force is transmitted to the door inner panel 6, so that the occupant is injured by the impact force.

따라서, 본 발명은 상기한 종래의 문제점을 해결하기 위하여 창안한 것으로, 차량의 외관이 미려하게 할 뿐아니라 도어 로워 사이드의 임팩트시 충격력을 흡수할 수 있도록 하여 차량의 측면 충돌시 탐승자의 안전을 도모할 수 있도록 하는 데 그 목적이 있다.Therefore, the present invention was devised to solve the above-mentioned conventional problems, which not only makes the appearance of the vehicle beautiful but also absorbs the impact force when the door lower side is impacted, thereby promoting the safety of the rider during a side collision of the vehicle. The purpose is to make it possible.

Coupled to the reinforcement piece to support the impact portion, and coupled to the outer surface of the impact portion, characterized in that it is configured as a door garnish to prevent the impact portion is exposed to the outside to be beautiful.

이하 첨부된 도면에 의해 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2 에서 나타낸 바와 같이, 본 발명은 하부에 삽입부(11)를 형성한 도어 외측 패널(10)과, 상기 삽입부(11)에 설치되고 측면의 충격력을 흡수하는 임팩트부(20)와, 도어 내측패널(13)의 공간부(9)에 삽입고정하되 상기 임팩트부(20)와 결합되어 임팩트부(20)를 지지하는 보강편(24)과, 상기 임팩트부(20)의 외측면에 결합되고 임팩트부(20)가 외부로 노출되는 것을 방지하여 외관이 미려할 수 있도록 한 도어 가니쉬(30)로 구성한다.As shown in FIG. 2, the present invention provides a door outer panel 10 having an inserting portion 11 formed at a lower portion thereof, an impact portion 20 installed at the inserting portion 11 and absorbing a side impact force, The reinforcement piece 24 which is inserted into and fixed to the space 9 of the door inner panel 13 and is coupled to the impact part 20 to support the impact part 20, and on the outer surface of the impact part 20. Combination is configured with a door garnish 30 to prevent the impact portion 20 is exposed to the outside so that the appearance is beautiful.

상기 임팩트부(20)는 중앙부에 통공(21a)을 형성하고 양 단을 절곡하며 단부를 다시 절곡하여 걸림돌기(21b)를 형성한 멤버Ⅰ(21)를 상기 도어 외측 패널(10)의 삽입부(11)에 설치하되, 멤버Ⅰ(21)의 통공(21a)이 삽입부(11)의 통공(12)에 일치하도록 설치한다.The impact part 20 includes a member I 21 having a through hole 21a formed at the center, bent at both ends, and bent at the end again to form a locking protrusion 21b, thereby inserting the door outer panel 10. It installs to (11), but installs so that the through-hole 21a of the member I21 may correspond to the through-hole 12 of the insertion part 11. As shown in FIG.

또한 양 단을 절곡하여 상기 멤버Ⅰ(21)의 외부를 덮을 수 있도록 하고, 중앙부가 상기 걸림돌기(21b)의 사이에 삽입 결합될 수 있도록 돌부(22a)를 형성하며, 돌부(22a)의 중앙에 통공(22b)을 형성한 멤버Ⅱ(22)를 설치하되, 상기 멤버Ⅰ(21)과 멤버Ⅱ(22)의 결합시 공간부(23)가 형성될 수 있도록 한다.In addition, both ends are bent to cover the outside of the member I 21, and a protrusion 22a is formed so that a central portion can be inserted and coupled between the locking protrusions 21b, and the center of the protrusion 22a. A member II (22) having a through hole (22b) is provided in the installation, so that the space portion 23 can be formed when the member I (21) and the member (II) 22 are combined.

상기 보강편(24)은 양단을 절곡하고 중앙에 통공(24a)을 형성하여 도어 외측 패널(10)과 도어 내측 패널(13)의 공간부(9)에 삽입 결합하되, 보강편(24)의 통공(24a)이 도어 외측 패널(10)의 통공(12)에 일치하도록 설치한다.The reinforcing piece 24 is bent at both ends and forms a through-hole 24a at the center to insert and engage the space portion 9 of the door outer panel 10 and the door inner panel 13, but the reinforcing piece 24 The through hole 24a is installed to coincide with the through hole 12 of the door outer panel 10.

또한 중앙부에 통공(25a)을 형성한 압축패드(25)를 상기 공간부(23)에 삽입 설치한다.In addition, the compression pad 25 having the through hole 25a formed in the center is inserted into the space 23.

이때 상기 멤버Ⅰ(21)과 멤버Ⅱ(22)와 보강편(24)과 압축패드(25)는 각각의 통공(21a, 22b, 24a, 25a)이 일치하도록 하고 도어 외측 패널(10)의 통공(12)에 일치하도록 한 후, 결합수단(26)으로 체결하여 결합 고정한다.At this time, the member I (21), the member II (22), the reinforcing piece 24 and the compression pad 25 are made to match the respective through holes (21a, 22b, 24a, 25a) and the through hole of the door outer panel 10 After making it match with (12), it is fastened by fastening with the coupling means (26).

상기와 같이 임팩트부(20)를 도어 외측 패널(10)의 하부에 설치한 후, 상기 멤버Ⅱ(22)의 외측면에 도어 가니쉬(30)를 접착부재(미도시)를 이용하여 부착한다.After the impact unit 20 is installed below the door outer panel 10 as described above, the door garnish 30 is attached to the outer surface of the member II 22 using an adhesive member (not shown).

상기와 같이 구성된 본 발명의 작용을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

차량의 측방향으로 충격력이 가해지면 도어 외측 패널(10)과 함께 도어 가니쉬(30)에 충격력이 전달되고 도어 가니쉬(30)는 충격력을 내측에 설치된 임팩트부(20)에 전달하면서 1차 충격력을 흡수하게 된다.When the impact force is applied to the side of the vehicle, the impact force is transmitted to the door garnish 30 together with the door outer panel 10, and the door garnish 30 transmits the impact force to the impact part 20 installed on the inner side, thereby transmitting the primary impact force. Will be absorbed.

상기와 같이 충격력이 임팩트부(20)에 전달되면 멤버Ⅱ(22)가 압축패드(25)를 압축하면서 멤버Ⅰ(21)에 밀착되면서 2차 충격력을 흡수하게 되며, 도어의 내측에 설치된 보강편(24)이 상기 멤버Ⅰ(21)이 내측으로 밀리는 것을 지지하여 최종 충격력을 흡수하는 것이다.When the impact force is transmitted to the impact part 20 as described above, the member II 22 compresses the compression pad 25 and absorbs the secondary impact force while being in close contact with the member I 21, and a reinforcing piece installed inside the door. (24) supports pushing the member I (21) inward to absorb the final impact force.

이때 상기 압축패드(25)는 상기 멤버Ⅰ(21)과 멤버Ⅱ(22)의 사이에서 멤버Ⅰ(21)과 멤버Ⅱ(22)의 충돌시 완충역할을 하는 것이다.At this time, the compression pad 25 acts as a buffer when the member I 21 and the member II 22 collide between the member I 21 and the member II 22.

이때 상기 도어 가니쉬(30)는 임팩트부(20)의 외측에 설치되므로, 차량의 도어부 외관이 미려할 수 있도록 하는 것이다.At this time, since the door garnish 30 is installed outside the impact part 20, the door part appearance of the vehicle may be beautiful.

이상에서 살펴본 바와 같이, 본 발명은 도어 로워 사이드 임팩트 흡수장치를 제공하여 차량의 외관이 미려하게 할 뿐아니라 도어 로워 사이드의 임팩트시 충격력을 흡수할 수 있도록 하여 차량의 측면 충돌시 탐승자의 안전을 도모할 수 있도록 한 것이다.As described above, the present invention provides a door lower side impact absorber to not only make the appearance of the vehicle beautiful, but also to absorb impact force during impact of the door lower side, thereby promoting the safety of the rider during a side collision of the vehicle. It is to be done.
