도 1a,b는 본 발명의 일 실시예를 보인 것으로, 도 1a는 파킹레버의 단면도이고, 도 1b는 도 1a에 따른 A부 확대도이다. 도시된 바와 같이 차량용 파킹레버(1)에는 그 일측 단부로 스프링(S1)에 의해 탄성지지되는 버튼(20)이 구비되고, 내측에는 상기 버튼(20)에 의해 작동되는 푸시로드(30)가 구비되며, 도 3에서 설명한 바와 같이 상기 시로드(30)의 작동에 따라 고정 및 해제되는 걸림턱(60)과 걸림부(70)가 구비된다.1A and 1B illustrate an embodiment of the present invention. FIG. 1A is a sectional view of a parking lever, and FIG. 1B is an enlarged view of a portion A according to FIG. 1A. As shown, the vehicle parking lever 1 has a button 20 which is elastically supported by a spring S1 at one end thereof, and a push rod 30 operated by the button 20 is provided at an inner side thereof. As illustrated in FIG. 3, the locking jaw 60 and the locking portion 70 which are fixed and released according to the operation of the sea rod 30 are provided.

이때, 상기 파킹레버(1)의 내측 선단부에는 내주면에 걸림턱(11)이 형성되는라이너(10)가 고정되고, 상기 버튼(20)은 상기 라이너(10)의 내측에 구비되되, 그 외주면에는 상기 걸림턱(11)이 삽입되는 환형의 홈부(21)가 형성되고, 하면으로 상기 푸시로드(30)의 끝단이 삽입되는 로드삽입홈(22)이 형성되며, 상기 로드삽입홈(22)에는 스프링(S2)이 내장되는 것을 특징으로 한다.At this time, the inner end of the parking lever 1 is fixed to the liner 10 is formed with a locking jaw 11 is formed on the inner peripheral surface, the button 20 is provided on the inner side of the liner 10, the outer peripheral surface An annular groove 21 into which the locking jaw 11 is inserted is formed, and a rod insertion groove 22 into which an end of the push rod 30 is inserted into a lower surface thereof is formed, and in the rod insertion groove 22. It is characterized in that the spring (S2) is built.

또한, 상기 파킹레버(1)의 내주면에는 스프링(S1)의 후방을 지지하는 걸림돌기(50)가 형성되고, 상기 스프링(S1)과 걸림돌기(50)의 사이에는 원통형의 스프링지지구(40)가 구비되어, 상기 스프링(S1)을 보다 확실하게 지지한다.In addition, a locking protrusion 50 supporting the rear of the spring S1 is formed on an inner circumferential surface of the parking lever 1, and a cylindrical spring support 40 is disposed between the spring S1 and the locking protrusion 50. ) Is provided to more reliably support the spring (S1).

도 2a,b는 도 1b에 따른 것으로, 도 2a는 버튼의 눌림상태를 보인 작동상태도이고, 도 2b는 파킹레버의 해제상태를 보인 작동상태도이다. 도시된 바와 같이 파킹레버(1)를 고정시켜 파킹 브레이크를 작동시킨 상태에서, 버튼(20)을 누르면 로드삽입홈(22)에 내장된 스프링(S2)에 압축이 발생된다.Figures 2a, b is in accordance with Figure 1b, Figure 2a is an operating state diagram showing the pressed state of the button, Figure 2b is an operating state diagram showing the release state of the parking lever. As illustrated, when the parking lever 1 is fixed to operate the parking brake, pressing the button 20 causes compression to occur in the spring S2 embedded in the rod insertion groove 22.

이때, 푸시로드(30)는 도 1a에 도시한 바와 같이 걸림턱(60)이 걸림부(70)에 물려 고정된 상태이며, 그 물림력에 의해 스프링(S2)이 압축되어도 원래의 상태를 유지하게 됨으로써, 버튼(20)이 운전자의 의도와 상관없이 눌러져도, 이로 인해 차량의 파킹상태가 해제되는 것을 방지할 수 있게 되는 것이다.At this time, the push rod 30 is a state in which the locking jaw 60 is fixed to the locking portion 70, as shown in Figure 1a, even if the spring (S2) is compressed by the biting force to maintain the original state By doing so, even if the button 20 is pressed regardless of the driver's intention, it is possible to prevent the parking state of the vehicle from being released.

또한, 상기한 바와 같이 버튼(20)을 누른 상태에서 파킹레버(1)를 살짝 들어올리면, 걸림부에 고정된 걸림턱이 상기 걸림부의 이빨을 누름으로써 발생되는 물림력이 약화되며, 그 순간 압축상태에 있던 스프링(S2)이 푸시로드(30)를 작동시킴으로써, 걸림턱이 걸림부로부터 이탈되어 파킹레버가 해제된다.In addition, if the parking lever 1 is slightly lifted while the button 20 is pressed as described above, the locking jaw fixed by the locking portion depresses the biting force generated by pressing the teeth of the locking portion, and compresses at that moment. As the spring S2 in the state operates the push rod 30, the locking jaw is released from the locking portion and the parking lever is released.

이때, 상기 스프링(S2)은 상기 걸림턱과 걸림부의 물림력에 비해 적은 탄성력을 갖는 것을 선택함으로써, 버튼(30)을 누르는 순간 상기 스프링(S2)의 탄성력에 의해 푸시로드(30)가 바로 작동되는 것을 미연에 방지하는 것이 바람직하다.At this time, the spring (S2) is selected to have a less elastic force than the engaging force of the locking jaw and the locking portion, the push rod 30 is immediately operated by the elastic force of the spring (S2) the moment the button 30 is pressed. It is desirable to prevent this from happening.

또한, 버튼(20)이 눌림에 따라 그 후방을 지지하는 스프링(S1)에도 압축이 발생됨으로써, 누름압력의 해제시 상기 스프링(S1)의 탄성력에 의해 상기 버튼(20)은 신속하게 원위치로 복귀하게 된다.In addition, as the button 20 is pressed, compression is also generated in the spring S1 supporting the rear thereof, so that the button 20 quickly returns to its original position by the elastic force of the spring S1 when the pressing pressure is released. Done.

이에 따라, 운전자가 파킹레버를 해제하고자 하는 경우에는 먼저 버튼을 누른 상태에서 상측으로 들어올리는 과정을 거쳐야 함으로써, 버튼이 운전자의 의도와 상관없이 눌러져도, 이로 인해 차량의 파킹상태가 해제되는 것을 방지할 수 있게 되는 것이다.Accordingly, when the driver wants to release the parking lever, the driver must first lift the button upward while pressing the button, thereby preventing the vehicle from releasing the parking state even if the button is pressed regardless of the driver's intention. You can do it.

상술한 바와 같이 본 발명은 버튼을 눌러도 파킹레버가 즉시 해제되지 않도록 구성하여, 파킹 브레이크가 불필요하게 해제되는 것을 방지할 수 있으므로, 불의의 사고를 예방할 수 있는 효과를 가진다.As described above, the present invention is configured such that the parking lever is not immediately released even when the button is pressed, and thus the parking brake can be prevented from being unnecessarily released, and thus, an accident can be prevented.
