이하, 첨부된 도면을 참조하여 본 발명의 일실시예를 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 변속레버 파킹장치의 구성도이다.2 is a block diagram of a shift lever parking apparatus according to the present invention.

본 발명에 일 실시예에 따른 변속레버 파킹장치는 변속 레버(2)와 변속 레버 브래킷(4) 사이의 힌지 연결부의 일측에 형성되어 변속 레버(2)의 현재 위치를 고정시키는 록킹부와, 전원이 인가되면 상기 록킹부의 푸시로드(8)를 직선 이동시키는 액추에이터(10)와, 차량이 주차 상태인 것으로 판단되면 상기 액추에이터(10)를 작동시키는 제어부로 구성된다.The shift lever parking device according to an embodiment of the present invention is formed on one side of the hinge connection portion between the shift lever 2 and the shift lever bracket 4 to lock the current position of the shift lever 2 and a power source. When applied, the actuator 10 is configured to linearly move the push rod 8 of the locking unit, and if it is determined that the vehicle is in a parking state, the actuator 10 is configured to operate the actuator 10.

상기 록킹부는 변속 레버의 힌지부(6) 일측에 형성되는 록킹홈(20)과, 상기 록킹홈(20)과 연통되는 위치의 변속 레버 브래킷(4)의 일측에 관통되는 관통홀(24)과, 상기 관통홀(24)을 통해 상기 록킹홈(20)에 끼워져 변속 레버(2)를 고정시키는 푸시로드(8)로 구성된다.The locking part includes a locking groove 20 formed at one side of the hinge part 6 of the shift lever, a through hole 24 penetrating at one side of the shift lever bracket 4 at a position in communication with the locking groove 20, and The push rod 8 is inserted into the locking groove 20 through the through hole 24 to fix the shift lever 2.

상기 액추에이터(10)는 상기 작동로드와 연결되어 푸시로드(8)를 직선 이동시키기 위한 것으로, 차량의 배터리 전원을 인가받아 푸시로드(8)를 직선 이동시킬 수 있는 솔레노이드 타입으로 형성되어짐이 바람직하다.The actuator 10 is connected to the operation rod to linearly move the push rod 8, and is preferably formed in a solenoid type capable of linearly moving the push rod 8 by receiving battery power from a vehicle. .

상기 제어부는 차량이 정지된 것으로 판단되면 상기 액추에이터(10)를 작동시키는 수단으로서, 차량의 현재 속도를 검출하는 차속 센서(14)와, 차량의 이그니션 키의 조작 위치를 인가하는 이그니션 키 스위치(12)와, 상기 이그니션 키 스위치(12) 및 차속 센서(14)로부터 인가되는 신호에 따라 현재 차량이 정지된 상태인 것으로 판단되면, 상기 액추에이터(10)로 전원을 인가하고, 차량이 시동된 것으로 판단되면 액추에이터(10)를 오프시키는 ECU(전자제어유닛)(16)을 구성된다.The control unit is a means for operating the actuator 10 when it is determined that the vehicle is stopped, a vehicle speed sensor 14 for detecting a current speed of the vehicle, and an ignition key switch 12 for applying an operation position of the ignition key of the vehicle. ), And when it is determined that the vehicle is in a stopped state according to the signals applied from the ignition key switch 12 and the vehicle speed sensor 14, power is supplied to the actuator 10, and the vehicle is started. When the actuator 10 is turned off, the ECU (electronic control unit) 16 is configured.

상기한 바와 같이 이루어진 본 발명에 따른 변속 레버의 작용을 다음에서 설명한다.The operation of the shift lever according to the present invention made as described above will be described below.

먼저 차속 센서(14) 및 이그니션 키 스위치(12)의 신호에 따라 현재 차량이 정지된 것으로 판단되면, ECU(16)는 액추에이터(10)로 배터리 전원을 인가한다. 그러면 액추에이터(10)가 작동되어 푸시로드(8)를 직선 이동시킨다.First, when it is determined that the vehicle is currently stopped according to the signals of the vehicle speed sensor 14 and the ignition key switch 12, the ECU 16 applies battery power to the actuator 10. The actuator 10 then operates to linearly move the push rod 8.

이때, 푸시로드(8)는 직선 이동되면서 변속 레버의 록킹홈(20)에 삽입되어 변속 레버(2)를 현재 위치에서 움직이지 않도록 고정시킨다.At this time, the push rod 8 is inserted into the locking groove 20 of the shift lever while linearly moving to fix the shift lever 2 so as not to move at the current position.

이러한 상태에서, 이그니션 키 스위치(12)로부터 인가되는 신호에 따라 차량이 출발하기 위해 시동 상태인 것으로 판단되면 상기 액추에이터(10)로 인가되는 전원을 차단한다. 그러면 액추에이터(10)에 설치된 리턴 스프링(28)의 작용에 따라 푸시로드(8)가 록킹홈(20)에 빠지면서 변속 레버(2)의 록킹을 해제한다.In such a state, when it is determined that the vehicle is in a starting state according to a signal applied from the ignition key switch 12, the power applied to the actuator 10 is cut off. Then, the push rod 8 falls into the locking groove 20 in response to the action of the return spring 28 installed on the actuator 10 to release the locking of the shift lever 2.

따라서, 상기와 같이 구성되고 작용되는 본 발명에 따른 변속 레버 록킹장치는 차량이 주차상태이면 액추에이터를 작동시켜 푸시로드를 밀어 변속 레버의 현재 위치에서 움직이지 않도록 록킹시킴으로써, 차량이 경사진 도로상에 주차된 상태에서 어린이나 운전자의 부주의로 변속레버를 움직어 기어빠짐 현상이 발생되면 차량이 저절로 움직이게 되어 대형 사고를 초래하는 것을 방지할 수 있는 이점이 있다.Therefore, the shift lever locking device according to the present invention constructed and operated as described above operates the actuator when the vehicle is parked to push the push rod to lock the shift lever so as not to move at the current position of the shift lever. When the shift lever is inadvertently shifted by a child or a driver while parked, the vehicle may move by itself, thereby preventing a large accident.
