Description

브레이크 페달의 취부구조체{Mounting structure of brake pedal}Mounting structure of brake pedal

본 발명은 브레이크 페달의 취부구조체에 관한 것으로, 특히 차량의 충돌사고시 브레이크 페달이 운전자측으로 부딪혀 부상을 입게 되는 것을 예방할 수 있도록 그 구조가 개선된 브레이크 페달의 취부구조체에 관한 것이다.The present invention relates to a mounting structure of the brake pedal, and more particularly, to a mounting structure of the brake pedal improved in the structure so as to prevent the brake pedal from being injured by the driver's side in the event of a crash of the vehicle.

일반적으로, 차량용 브레이크 시스템은 주행중의 자동차를 감속 또는 정지시킴과 동시에 주차상태를 유지시키기 위해 사용되는 장치로서, 마찰력을 이용하여 운동 에너지를 열 에너지로 전환한 후에 이 열 에너지를 대기중으로 발산하여 제동작용을 하게 된다.In general, a vehicle brake system is a device used to keep a car parked while decelerating or stopping a vehicle while driving, and converts kinetic energy into thermal energy using friction force and then radiates the thermal energy into the air to brake the vehicle. It works.

그 브레이크 시스템은 운전자의 제동의지를 운동에너지로 변환시키는 브레이크 페달과, 그 브레이크 페달과 연동하여 브레이크 조작시 진공압과 공기압의 차로 배력을 발생시키는 부스터와, 그 부스터와 연동하여 유압을 발생시키는 마스터 실린더와, 그 마스터 실린더의 일측 유로에서 출력되는 유압에 의하여 차량의 휠을 제동하는 브레이크 어셈블리로 대별된다.The brake system includes a brake pedal that converts the driver's braking will into kinetic energy, a booster that generates power by the difference between vacuum pressure and air pressure during brake operation in conjunction with the brake pedal, and a master that generates hydraulic pressure in conjunction with the booster. A cylinder and a brake assembly for braking a wheel of a vehicle by hydraulic pressure output from one flow path of the master cylinder are roughly classified.

그중 종래 브레이크 페달의 설치구조는 도 6에 도시된 바와 같이, 차실내와 엔진룸 사이를 구분하는 대쉬패널(20)에 결합된 브라켓(40)에 페달 아암(11)이 힌지점을 매개로 회동가능하게 설치되고, 그 페달 아암(11)에 부스터(30)와 연결되는 작동로드(50)의 일단부가 결합된다.Among them, as shown in FIG. 6, the conventional brake pedal mounting structure rotates through the hinge point of the pedal arm 11 on the bracket 40 coupled to the dash panel 20 for distinguishing between the vehicle interior and the engine room. It is possibly installed, and one end of the actuating rod 50 coupled with the booster 30 is coupled to the pedal arm 11.

이러한 구조의 종래 브레이크 페달의 설치구조는 제동시 운전자가 브레이크페달(10)을 밟으면, 브라켓(40)에 회동가능하게 지지된 페달 아암(11)이 회동하고, 이어서 그 페달 아암(11)에 의해 작동로드(50)가 전진하게 되고, 이 전진되는 작동로드(50)에 의해 부스터(30)에 배력이 발생함과 아울러, 마스터 실린더(미도시)에서 브레이크 어셈블리(미도시됨)를 작동시키기 위한 작동유압이 발생하게 된다.In the conventional brake pedal mounting structure of this structure, when the driver presses the brake pedal 10 during braking, the pedal arm 11 rotatably supported by the bracket 40 is rotated, and then by the pedal arm 11. The actuation rod 50 is advanced, and the boosting force 30 is generated by the actuating rod 50, and the brake rod (not shown) is operated to operate the master cylinder (not shown). Hydraulic pressure is generated.

종래의 차량은 주행중 충돌사고 발생시 차체에 가해지는 충격력에 의해 충격부위가 반대방향으로 밀리면서 형태가 달라지게 된다.Conventional vehicles are changed in shape while the impact portion is pushed in the opposite direction by the impact force applied to the vehicle body when a collision accident occurs while driving.

이때 브레이크 페달은 힌지점을 중심으로 반 시계방향으로 회전되어 운전자의 하체부위에 충격을 가해 치명적인 부상을 입히게 될 위험이 있었다.At this time, the brake pedal was rotated counterclockwise around the hinge point, and there was a risk of causing a fatal injury by impacting the lower part of the driver.

본 발명은 상기한 제반문제점을 감안하여 이를 해결하고자 안출된 것으로, 그 목적은 주행중 충돌사고시 브레이크 페달이 운전자의 하체부위측으로 부딪히게 되는 것을 방지하도록 그 구조가 개선된 브레이크 페달의 취부구조체를 제공하는 데 있다.The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a mounting structure of a brake pedal whose structure is improved to prevent the brake pedal from colliding with the lower body part of the driver during a crash accident while driving. There is.

The case 230 is penetrated and coupled to the rear surface of the second panel unit 120 and the fixing pieces 215 are accommodated therein, and penetrates to the side of the case 230 so as to be protruded to the outside. Fixed pins 220 coupled to each of the fixing holes 215a, and connected to the fixing pins 220 and the second panel unit 120, and the fixing pins 220 in case of a crash, and the case 230 and the bracket. It is composed of a wire member 240 to be separated from the (210).

또한, 케이스(230)는 그 내부에 고정핀(220)을 파지하기 위하여 자석으로 된파지부(235)가 설치되고, 일측면에는 고정핀(220)이 관통되도록 통공(232)이 형성되어 있다.In addition, the case 230 has a magnet gripping portion 235 is installed to hold the fixing pin 220 therein, and a through hole 232 is formed on one side thereof so that the fixing pin 220 penetrates.

이러한 구조를 갖는 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention having such a structure is as follows.

먼저, 그 결합과정을 설명하면, 브레이크 페달(10)을 브라켓(210)에 힌지 운동되도록 결합시킨 후에, 그 브라켓(210)의 고정편(215)이 제 1패널부(110)와 제 2패널부(120)를 관통하여 케이스(230)의 내부에 수용되도록 한다.First, the coupling process will be described. After the brake pedal 10 is coupled to the bracket 210 by the hinge movement, the fixing piece 215 of the bracket 210 is connected to the first panel 110 and the second panel. It penetrates through the unit 120 to be accommodated in the case 230.

이어서, 고정핀(220)을 케이스(230)의 통공(232)을 통해 고정편(215)의 고정공(215a)에 삽입되도록 결합시킨 후에 파지부(235)에 결합시킨다.Subsequently, the fixing pin 220 is coupled to be inserted into the fixing hole 215a of the fixing piece 215 through the through hole 232 of the case 230, and then coupled to the holding part 235.

또한, 브레이크 페달(10)의 페달 아암(11)과 부스터(30) 사이에 마련된 제 1,2로드부(310,320)를 볼트(410)와 너트(420)를 이용하여 축 결합시킨다.In addition, the first and second rod parts 310 and 320 provided between the pedal arm 11 and the booster 30 of the brake pedal 10 are axially coupled using the bolt 410 and the nut 420.

이때, 제 1,2로드부(310,320)의 제 1,2스톱퍼(315,325)를 상호 록킹 결합시켜 제 1,2로드부(310,320)가 회전되지 않도록 함으로써, 평상시 브레이크 페달(10)의 답력을 부스터(30)에 전달할 수 있도록 한다.At this time, by locking the first and second stoppers 315 and 325 of the first and second rod parts 310 and 320 to each other so that the first and second rod parts 310 and 320 are not rotated, the boosting force of the brake pedal 10 is normally boosted. To be delivered to (30).

이후에, 고정핀(220)의 단부를 와이어부재(240)를 이용하여 제 2패널부(120)에 고정되도록 결합시키며, 이 와이어부재(240)의 고정작업은 볼트 또는 나사등의 체결부재를 이용한다.Thereafter, the end of the fixing pin 220 is coupled to the second panel unit 120 using the wire member 240 to be fixed, and the fixing of the wire member 240 is performed by fastening members such as bolts or screws. I use it.

이러한 조립과정이 완료된 후에 평상시에는 운전자가 브레이크 페달(10)을밟을 경우, 브레이크 페달(10)의 답력이 제 2로드부(320)와 제 1로드부(310)를 거쳐 부스터(30)측으로 전달되어 기존의 브레이크 제동과정과 동일한 과정이 이루어진다.When the driver normally presses the brake pedal 10 after the assembly process is completed, the pedal pedal 10 transmits the stepping force to the booster 30 through the second rod part 320 and the first rod part 310. Therefore, the same process as the conventional brake braking process is performed.

한편, 충돌사고가 발생할 경우에는, 운전자가 브레이크 페달(10)에 발을 올려 놓는 것과 관계없이, 부스터(30)측에서 충돌에너지가 제 2패널부(120)와 제 3패널부(130)측으로 전달되어 그 형태가 변형된다.On the other hand, when a crash occurs, regardless of the driver's foot on the brake pedal 10, the collision energy from the booster 30 side to the second panel portion 120 and the third panel portion 130 side. Is transmitted and its shape is modified.

이때, 제 1,2,3패널부(110,120,130)의 결합구조에서 일정 충격력이상의 에너지가 전달될 때 리벳팅결합된 상태가 해제되어 상호 분리된다.At this time, in the coupling structure of the first, second, third panel parts 110, 120, 130, when the energy of a predetermined impact force or more is transmitted, the riveted state is released and separated from each other.

이어서, 제 2패널부(120)의 형태가 변형됨에 따라 그 제 2패널부(120)와 결합된 와이어부재(240)에 긴장력이 작용하게 되어 고정핀(220)을 당기는 힘으로 작용하게 된다.Subsequently, as the shape of the second panel portion 120 is deformed, a tension force acts on the wire member 240 coupled to the second panel portion 120 to act as a force for pulling the fixing pin 220.

이에 따라, 고정핀(220)은 파지부(235)로부터 이탈됨과 아울러, 고정편(215)의 고정공(215a)과 케이스(230)의 통공(232)을 이탈하게 된다.Accordingly, the fixing pin 220 is separated from the gripping portion 235 and the fixing pin 215 is separated from the fixing hole 215a of the fixing piece 215 and the through hole 232 of the case 230.

이는 제 2패널부(120)가 브라켓(210)의 고정편(215) 및 제 1패널부(110)와 분리되어 브레이크 페달(10)측으로 충격에너지가 전달되지 않게 됨을 의미한다.This means that the second panel unit 120 is separated from the fixing piece 215 and the first panel unit 110 of the bracket 210 so that the impact energy is not transmitted to the brake pedal 10 side.

또, 제 3패널부(130)는 충돌사고시 형태가 변형되면서 제 1패널부(110)와 분리되어 차체의 플로어패널측으로 밀리게 된다.In addition, the third panel unit 130 is separated from the first panel unit 110 while being deformed in a crash accident and is pushed toward the floor panel side of the vehicle body.

한편, 상기한 제 2,3패널부(120,130)의 변형은 충돌사고시의 충격에너지를 흡수하는 역할을 수행하게 된다.Meanwhile, the deformation of the second and third panel units 120 and 130 serves to absorb impact energy during a crash accident.

이상과 같이 설명한 본 발명은 차량의 충돌사고시 충격력이 브레이크 페달측으로 전달되지 않도록 그 구조가 개량된 것인 바, 이에 따르면 본 발명은 충돌사고시 그 충격력에 의해 브레이크 페달과 결합된 대쉬패널이 복수개로 분리되도록 함으로써, 브레이크 페달측으로 전달되는 충격력을 차단 및 흡수하여 운전자의 상해를 예방할 수 있는 효과를 갖는다.As described above, the present invention is improved in the structure so that the impact force is not transmitted to the brake pedal side in a crash accident of the vehicle, and according to the present invention, the dash panel coupled to the brake pedal is separated into a plurality of dash panels by the impact force in the crash accident. By doing so, it is possible to block and absorb the impact force transmitted to the brake pedal side to prevent the injury of the driver.
