가속페달모듈{Acceleration Pedal Module}Acceleration Pedal Module

본 발명은 가속페달모듈에 관한 것으로서, 특히 가속페달모듈을 대시패널에 장착함에 있어 합성수지 재질의 장착패드가 파손되지 않게 구성한 것이다.The present invention relates to an accelerator pedal module, and in particular, the mounting pad made of a synthetic resin material is not damaged when mounting the accelerator pedal module on a dash panel.

차량에는 주행속도를 가속하기 위한 가속기가 장착되며, 운전자는 대시패널에 장착된 가속페달모듈의 페달을 밟음으로써, 차량의 주행속도를 가속시키고, 페달을 놓음으로써 감속시킨다. 이와 같이 대시패널에 장착된 가속페달모듈은 운전자가 가하는 힘을 받게 된다.The vehicle is equipped with an accelerator for accelerating the driving speed, and the driver accelerates the driving speed of the vehicle by depressing the pedal of the accelerator pedal module mounted on the dash panel and decelerates by releasing the pedal. Thus, the accelerator pedal module mounted on the dash panel receives the force applied by the driver.

도 1은 종래 기술에 따른 가속페달모듈을 대시패널에 장착한 상태를 나타낸 단면도이고, 도 2는 도 1에 도시된 가속페달모듈의 합성수지 장착패드에 균열이 발생한 상태를 나타낸 개략도이다.1 is a cross-sectional view showing a state in which the accelerator pedal module according to the prior art is mounted on the dash panel, Figure 2 is a schematic diagram showing a state in which a crack occurs in the synthetic resin mounting pad of the accelerator pedal module shown in FIG.

도 1에 도시된 같이, 가속페달모듈(10)을 대시패널(1)에 장착하기 위해서, 볼트(3)가 대시패널(1)을 관통한 상태로 볼트(3)의 헤드(3h)는 대시패널(1)의 안쪽에 위치하고 나사부(3s)는 대시패널(1)을 관통해 운전석 쪽을 향해 위치한다. As shown in FIG. 1, in order to mount the accelerator pedal module 10 to the dash panel 1, the head 3h of the bolt 3 is dashed with the bolt 3 passing through the dash panel 1. Located inside the panel 1, the threaded portion 3s passes through the dash panel 1 and is located toward the driver's seat.

상기 볼트(3)는 대시패널(1)에 용접고정된다. 이때 대시패널(1)의 안쪽과 나사부(3s)를 용접 고정한다. 그럼으로써, 볼트(3)의 나사부(3s)와 대시패널(1)의 안 쪽 접하는 부위에 용접비드(5)가 형성된다.The bolt 3 is welded to the dash panel 1. At this time, the inside and the screw portion (3s) of the dash panel (1) is fixed by welding. Thereby, the welding bead 5 is formed in the part which contact | abuts the threaded part 3s of the bolt 3 and the dash panel 1 inside.

이와 같이 대시패널(1)에 고정된 볼트(3)에 부시(15)를 끼우고, 가속페달모듈(10)을 볼트(3)에 고정한다. In this way, the bush 15 is inserted into the bolt 3 fixed to the dash panel 1, and the accelerator pedal module 10 is fixed to the bolt 3.

한편, 가속페달모듈(10)의 합성수지 재질의 장착패드(11)를 사출 제조할 시에 상기 볼트(3)가 관통할 구멍(13)을 형성해 두는데, 상기 구멍(13)에는 부시(15)가 위치한 상태로 부시(15)에 상기 볼트(3)의 나사부(3s)가 삽입된다. 그리고 볼트(3)의 나사부(3s) 단부에 너트(7)가 체결됨에 따라 장착패드(11)는 대시패널(1)에 밀착된 상태로 고정된다.On the other hand, when the injection pad 11 of the synthetic pedal material of the accelerator pedal module 10 is manufactured by injection molding, a hole 13 through which the bolt 3 is to be formed is formed, and the bush 13 has a bush 15. The threaded portion 3s of the bolt 3 is inserted into the bush 15 in a state where it is positioned. And as the nut 7 is fastened to the end of the threaded portion 3s of the bolt 3, the mounting pad 11 is fixed in close contact with the dash panel 1.

한편, 장착패드(11)에 형성된 구멍(13)의 위치 및 개수에 맞게 대시패널(1)에 볼트(3)가 고정된다.Meanwhile, the bolt 3 is fixed to the dash panel 1 in accordance with the position and the number of the holes 13 formed in the mounting pad 11.

하지만, 도 2에 도시된 바와 같이, 가속페달모듈(10)을 대시패널(1)에 장착함에 있어서, 볼트(3)의 직경 밖으로 형성된 용접비드(5)와 부시(15)의 단부가 접하게 되는데, 이 상태에서 볼트(3)에 너트(7)를 체결하고 조이면, 볼트(3)와 너트(7)의 체결력에 의해 부시(15)가 용접비드(5)를 가압하게 되고, 부시(15)가 용접비드(5)에 밀려 확장된다.However, as shown in FIG. 2, in mounting the accelerator pedal module 10 to the dash panel 1, the ends of the weld bead 5 and the bush 15 formed outside the diameter of the bolt 3 come into contact with each other. In this state, when the nut 7 is fastened and tightened to the bolt 3, the bush 15 presses the welding bead 5 by the fastening force between the bolt 3 and the nut 7, and the bush 15. Is pushed by the welding bead 5 and expanded.

이와 같이 부시(15)의 끝단이 확장되면, 합성수지 재질의 장착패드(11)가 가압되어 균열이 발생하게 된다.When the end of the bush 15 is expanded in this way, the mounting pad 11 made of synthetic resin is pressed to cause cracking.

볼트에 의해 균열이 발생한 상태에서, 운전자가 가속페달을 밟아 가압하면 균열이 성장하여 결국 가속페달모듈인 대시패널에서 탈락되는데, 운전 중에 가속페달모듈이 탈락되면 사고로 이어질 위험성이 있다.If the driver presses the accelerator pedal under pressure in the cracked state, the crack grows and is eventually dropped from the dash panel, which is an accelerator pedal module. If the accelerator pedal module is dropped during operation, there is a risk of an accident.

본 발명은 앞에서 설명한 바와 같은 종래의 기술의 문제점을 해결하기 위하여 발명된 것으로서, 대시패널에 고정된 볼트에 가속페달모듈을 장착함에 있어 가속페달모듈의 사출물인 장착패드가 파손되는 것을 방지하도록 구성한 가속페달모듈을 제공하는 데 그 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above, the acceleration configured to prevent the mounting pad which is the injection pad of the accelerator pedal module is damaged in mounting the accelerator pedal module to the bolt fixed to the dash panel The purpose is to provide a pedal module.

Therefore, a welding bead 5 is formed between the bolt 3 and the dash panel 1 by welding. On the other hand, the mounting pad 110 of the accelerator pedal module 100 is positioned in the dash panel 1 so that the bolt 3 fixed to the dash panel 1 is inserted into the bush 115.

그리고 부시(115)에 볼트(3)를 끼우면 볼트(3)에 형성된 용접비드(5)는 부시(115)의 단부에 접하게 되고, 이 상태에서 볼트(3)의 끝단에 너트(7)를 체결하고 조이면, 너트(7)에 밀려 장착패드(110)가 대시패널(1)에 밀착되는데, 이때 용접비드(5)에 의해 부시(115) 단부가 바깥방향으로 확장되는 형태로 변형된다.When the bolt 3 is inserted into the bush 115, the welding bead 5 formed in the bolt 3 comes into contact with the end of the bush 115, and in this state, the nut 7 is fastened to the end of the bolt 3. When tightened, the mounting pad 110 is pushed by the nut 7 to be in close contact with the dash panel 1, whereby the end of the bush 115 is extended to the outside by the welding bead 5.

이와 같이 부시(115)의 단부가 바깥방향으로 확장되더라도 부시(115)의 단부 바깥쪽에는 홈(113)이 형성됨으로써, 홈(113)의 안쪽으로 부시(115)의 단부가 변형되어 들어간다.As described above, even when the end portion of the bush 115 extends outward, a groove 113 is formed outside the end portion of the bush 115, so that the end portion of the bush 115 is deformed into the groove 113.

따라서 부시(115)의 단부가 변형되더라도 사출품인 장착패드(110)를 가압하지 않게 되며, 장착패드(110)에 균열이 발생하지 않게 된다.Therefore, even if the end of the bush 115 is deformed does not press the mounting pad 110, which is an injection molded product, the crack does not occur in the mounting pad 110.
