일반적으로 테일게이트(tail gate)는 스테이션 왜건, 스포츠 유틸리티 차량(SUV: sport utility vehicle), 픽업트럭 등의 후방측에 설치된다. 테일게이트에는 2방향으로 개방되는 2웨이 테일게이트가 있다. 2웨이 테일게이트는 상하방향으로 개방되는 상하오픈 타입의 테일게이트와, 좌우방향으로 개방되는 좌우오픈 타입의 테일게이트가 있다. 테일게이트에는 테일게이트의 스트라이커를 구속 및 해제하도록 테일게이트 래치가 설치된다. 테일게이트 래치에는 스트라이커가 일방향으로 인입되도록 인입홀부가 형성되고, 인입홀부의 일측을 개폐시키도록 개폐 레버가 설치된다.In general, a tail gate is installed at the rear side of a station wagon, a sport utility vehicle (SUV), a pickup truck, or the like. The tailgate has a 2-way tailgate that opens in two directions. Two-way tailgate includes a vertical open-type tailgate that opens in a vertical direction, and a left-right open-type tailgate that opens in a left-right direction. A tailgate latch is installed on the tailgate to constrain and release the striker of the tailgate. In the tailgate latch, an inlet hole is formed so that the striker is inserted in one direction, and an opening/closing lever is installed to open and close one side of the inlet hole.
그러나, 종래에는 테일게이트 래치에 스트라이커가 일방향으로 인입되므로, 2웨이 테일게이트의 경우 제1 테일게이트를 먼저 개방시킨 후 제2 테일게이트를 개방시킨다. 또한, 제2 테일게이트를 먼저 닫은 후 제1 테일게이트를 나중에 닫는다. 따라서, 제1 테일게이트와 제2 테일게이트의 개폐순서가 정해지는 문제점이 있다. 따라서, 이를 개선할 필요성이 요청된다.However, in the related art, since the striker is inserted into the tailgate latch in one direction, in the case of a 2-way tailgate, the first tailgate is opened first and then the second tailgate is opened. In addition, the second tailgate is closed first and then the first tailgate is closed later. Accordingly, there is a problem in that the order of opening and closing of the first tail gate and the second tail gate is determined. Therefore, there is a need to improve this.

When the detection lever part 210 is rotated by the striker 10, the magnet part 222 corresponds to the hall sensor part 224, and the hall sensor part 224 detects the magnet part 222 to generate a detection signal. It is transmitted to the control unit (not shown). When a signal is received from the hall sensor unit 224, the control unit drives the motor unit 122 to rotate the sector cam unit 140 clockwise.
섹터캠부(140)가 시계방향으로 회전됨에 따라 파울부(170)와 릴리즈 레버부(160)가 시계방향으로 회전되고, 릴리즈 레버부(160)의 제2 릴리즈 가압부(166)가 하측으로 이동됨에 따라 클로징 레버부(180)의 구속이 해제된다. 클로징 레버부(180)가 탄성부재의 탄성력에 의해 반시계방향으로 회전되면서 인입홀부(112)의 일측을 폐쇄한다. 이와 동시에, 클라우부(150)가 시계방향으로 회전됨에 따라 클라우 구속부(154)가 인입홀부(112)의 타측을 폐쇄한다.As the sector cam unit 140 rotates clockwise, the foul unit 170 and the release lever unit 160 are rotated clockwise, and the second release pressing unit 166 of the release lever unit 160 moves downward. Accordingly, the restraint of the closing lever unit 180 is released. As the closing lever unit 180 is rotated counterclockwise by the elastic force of the elastic member, one side of the inlet hole 112 is closed. At the same time, as the claw portion 150 rotates in a clockwise direction, the claw restraining portion 154 closes the other side of the inlet hole 112.
상기와 같이 구성되는 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치의 작동에 관해 설명하기로 한다.The operation of the latch device for a tailgate for a vehicle according to an embodiment of the present invention configured as described above will be described.
먼저, 테일게이트가 개방될 때에 하우징의 인입홀부의 양측이 개방되는 과정에 관해 설명하기로 한다.First, when the tailgate is opened, a process in which both sides of the inlet hole portion of the housing are opened will be described.
도 8은 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치에서 종동 기어부가 반시계방향으로 회전됨에 따라 섹터캠부가 반시계방향으로 이동되는 상태를 도시한 평면도이고, 도 9는 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치에서 섹터캠부의 제1 섹터 가압부가 릴리즈 레버부의 롤러부에 접촉되는 상태를 도시한 평면도이고, 도 10은 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치에서 클라우부가 반시계방향으로 회전되고 클로징 레버부가 시계방향으로 회전되는 상태를 도시한 평면도이고, 도 11은 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치에서 클라우부와 클로징 레버부가 인입홀부의 양측을 개방하는 상태를 도시한 평면도이다.FIG. 8 is a plan view showing a state in which a sector cam part moves in a counterclockwise direction as a driven gear part rotates in a counterclockwise direction in a latch device for a tailgate for a vehicle according to an embodiment of the present invention. A plan view showing a state in which the first sector pressing part of the sector cam part is in contact with the roller part of the release lever part in the latch device of the tailgate for a vehicle according to an embodiment. A plan view showing a state in which the claw portion is rotated counterclockwise and the closing lever portion is rotated clockwise in the latch device. FIG. 11 is a claw portion and a closing lever portion in the latch device of a tailgate for a vehicle according to an embodiment of the present invention. It is a plan view showing a state in which both sides of the inlet hole are opened.
도 8 내지 도 11을 참조하면, 모터부(122)가 일방향으로 구동됨에 따라 구동 기어부(120)가 반시계방향으로 회전된다. 구동 기어부(120)가 반시계방향으로 회전됨에 따라 종동 기어부(130)가 시계방향으로 회전된다. 이때, 섹터캠부(140)의 섹터 톱니(143)가 종동 기어부(130)의 제2 종동 기어(134)에 맞물려 회전되므로, 섹터캠부(140)가 반시계방향으로 회전된다. 섹터캠부(140)가 반시계방향으로 회전됨에 따라 제1 섹터 가압부(144)도 반시계방향으로 회전된다.8 to 11, as the motor unit 122 is driven in one direction, the driving gear unit 120 is rotated in a counterclockwise direction. As the driving gear unit 120 is rotated counterclockwise, the driven gear unit 130 is rotated clockwise. At this time, since the sector teeth 143 of the sector cam unit 140 are rotated by meshing with the second driven gear 134 of the driven gear unit 130, the sector cam unit 140 is rotated in a counterclockwise direction. As the sector cam 140 is rotated counterclockwise, the first sector pressing unit 144 is also rotated counterclockwise.
이때, 클라우부(150)는 파울부(170)에 의해 지지됨에 따라 섹터캠부(140)와 함께 회전되지 않는다. 즉, 섹터캠부(140)가 일정 각도 회전되는 동안에 클라우부(150)는 정지된 상태를 유지한다.At this time, the claw part 150 is supported by the foul part 170 and thus does not rotate together with the sector cam part 140. That is, while the sector cam unit 140 is rotated by a certain angle, the cloud unit 150 maintains a stopped state.
제1 섹터 가압부(144)가 릴리즈 레버부(160)의 롤러부(162)를 가압하면, 릴리즈 레버부(160)가 반시계방향으로 회전된다. 릴리즈 레버부(160)가 반시계방향으로 회전됨에 따라 릴리즈 레버부(160)의 제1 릴리즈 가압부(164)가 파울부(170)의 파울 보스부(172)를 가압한다. 파울 보스부(172)가 릴리즈 레버부(160)에 의해 가압됨에 따라 파울부(170)가 반시계방향으로 회전된다. 파울부(170)가 반시계방향으로 회전됨에 따라 파울부(170)가 클라우부(150)의 지지력을 해제하면, 클라우부(150)가 탄성부재의 탄성력에 의해 반시계방향으로 회전된다. 또한, 릴리즈 레버부(160)의 제2 릴리즈 가압부(166)가 반시계방향으로 회전되면서 클로징 레버부(180)를 가압하면, 클로징 레버부(180)가 시계방향으로 회전된다. When the first sector pressing unit 144 presses the roller unit 162 of the release lever unit 160, the release lever unit 160 is rotated counterclockwise. As the release lever unit 160 is rotated counterclockwise, the first release pressing unit 164 of the release lever unit 160 presses the foul boss unit 172 of the foul unit 170. As the foul boss part 172 is pressed by the release lever part 160, the foul part 170 is rotated counterclockwise. As the foul part 170 rotates counterclockwise, when the foul part 170 releases the supporting force of the claw part 150, the claw part 150 is rotated counterclockwise by the elastic force of the elastic member. In addition, when the second release pressing unit 166 of the release lever unit 160 is rotated counterclockwise and presses the closing lever unit 180, the closing lever unit 180 is rotated clockwise.
클라우부(150)가 반시계방향으로 회전됨에 따라 클라우부(150)의 클라우 구속부(154)가 인입홀부(112)의 일측을 개방하고, 클로징 레버부(180)가 시계방향으로 회전됨에 따라 인입홀부(112)의 타측을 개방한다. 클라우부(150)와 클로징 레버부(180)가 인입홀부(112)의 양측을 모두 개방시키므로, 스트라이커(10)가 인입홀부(112)의 양측으로 이동이 가능해진다. 따라서, 한 쌍의 테일게이트 중 어느 하나를 먼저 개방할 수 있으므로, 테일게이트의 개폐 순서가 정해지지 않고 자유로워질 수 있다.As the claw part 150 is rotated counterclockwise, the claw restraining part 154 of the claw part 150 opens one side of the inlet hole 112, and the closing lever part 180 rotates in a clockwise direction. The other side of the inlet hole 112 is opened. Since the cloud part 150 and the closing lever part 180 open both sides of the inlet hole 112, the striker 10 can move to both sides of the inlet hole 112. Accordingly, since any one of the pair of tailgates can be opened first, the order of opening and closing the tailgates is not determined and can be freed.
다음으로, 테일게이트가 닫힐 때에 하우징(110)의 인입홀부(112)의 양측이 폐쇄되는 과정에 관해 설명하기로 한다. 이 과정에서 테일게이트가 불완전하게 닫힐 때에 클라우부(150)가 스트라이커(10)를 가압하여 테일게이트가 완전히 닫히게 하는 신칭(chinching) 기능도 수행한다.Next, a description will be given of a process in which both sides of the inlet hole 112 of the housing 110 are closed when the tailgate is closed. In this process, when the tailgate is incompletely closed, the claw unit 150 presses the striker 10 to completely close the tailgate.
도 12는 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치에서 스트라이커가 인입홀부에 인입되는 상태를 도시한 평면도이고, 도 13은 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치에서 스트라이커가 감지 레버부를 가압하여 시계방향으로 회전되는 상태를 도시한 평면도이고, 도 14는 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치에서 구동 기어부가 시계방향으로 회전됨에 따라 섹터캠부가 시계방향으로 회전되는 상태를 도시한 평면도이고, 도 15는 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치에서 클라우부와 클로징 레버부가 인입홀부의 양측을 폐쇄하도록 회전되는 상태를 도시한 평면도이고, 도 16은 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치에서 클라우부와 클로징 레버부가 인입홀부의 양측을 폐쇄한 상태를 도시한 평면도이다.12 is a plan view showing a state in which a striker is inserted into an entry hole in a latch device for a tailgate for a vehicle according to an embodiment of the present invention, and FIG. 13 is a latch device for a tailgate for a vehicle according to an embodiment of the present invention. A plan view showing a state in which the striker is rotated in a clockwise direction by pressing the sensing lever. FIG. 14 is a sector cam part clockwise as the driving gear part is rotated in a clockwise direction in the latch device for a vehicle tailgate according to an embodiment of the present invention. It is a plan view showing a state rotated in the direction, and FIG. 15 is a plan view showing a state in which the claw part and the closing lever part are rotated to close both sides of the inlet hole part in the latch device of the tailgate for a vehicle according to an embodiment of the present invention. , FIG. 16 is a plan view showing a state in which the claw portion and the closing lever portion close both sides of the inlet hole portion in the latch device of the tailgate for a vehicle according to an embodiment of the present invention.
도 12 내지 도 16을 참조하면, 스트라이커(10)가 인입홀에 인입되기 이전에는 마그네트부(222)와 홀센서부(224)가 어긋난 위치에 배치된다. 스트라이커(10)가 인입홀부(112)의 양측 중 어느 한 방향으로 인입홀에 인입되면, 스트라이커(10)가 감지 레버부(210)를 가압한다. 감지 레버부(210)가 시계방향으로 회전됨에 따라 마그네트부(222)와 홀센서부(224)가 대향된다. 홀센서부(224)가 감지된 신호를 제어부에 전송하면, 제어부는 스트라이커(10)가 인입홀부(112)에 인입되었다고 판단한다.12 to 16, before the striker 10 is inserted into the inlet hole, the magnet unit 222 and the hall sensor unit 224 are disposed at a position that is shifted. When the striker 10 is inserted into the inlet hole in either direction of both sides of the inlet hole 112, the striker 10 presses the sensing lever unit 210. As the detection lever part 210 rotates in a clockwise direction, the magnet part 222 and the hall sensor part 224 face each other. When the hall sensor unit 224 transmits the detected signal to the control unit, the control unit determines that the striker 10 has entered the lead-in hole unit 112.
제어부는 모터부(122)를 타방향으로 구동시킨다. 모터부(122)가 타방향으로 구동됨에 따라 구동 기어부(120)가 시계방향으로 회전된다. 구동 기어부(120)가 시계방향으로 회전됨에 따라 종동 기어부(130)가 반시계방향으로 회전된다. 이때, 섹터캠부(140)의 섹터 톱니(143)가 종동 기어부(130)의 제2 종동 기어(134)에 맞물려 회전되므로, 섹터캠부(140)가 시계방향으로 회전된다.The control unit drives the motor unit 122 in the other direction. As the motor unit 122 is driven in the other direction, the driving gear unit 120 is rotated in a clockwise direction. As the driving gear unit 120 is rotated in a clockwise direction, the driven gear unit 130 is rotated in a counterclockwise direction. At this time, since the sector teeth 143 of the sector cam unit 140 are rotated by meshing with the second driven gear 134 of the driven gear unit 130, the sector cam unit 140 is rotated in a clockwise direction.
섹터캠부(140)가 시계방향으로 회전됨에 따라 섹터캠부(140)의 제2 섹터 가압부(145)가 클라우 보스부(152)를 시계방향으로 가압한다. 제2 섹터 가압부(145)가 클라우 보스부(152)를 시계방향으로 회전시킴에 따라 클라우부(150)가 시계방향으로 회전된다. As the sector cam unit 140 rotates in the clockwise direction, the second sector pressing unit 145 of the sector cam unit 140 presses the claw boss unit 152 in the clockwise direction. As the second sector pressing portion 145 rotates the claw boss portion 152 in a clockwise direction, the claw portion 150 is rotated in a clockwise direction.
섹터캠부(140)가 시계방향으로 회전됨에 따라 제1 섹터 가압부(144)가 릴리즈 레버부(160)의 롤러부(162)에서 이격된다. 이때, 릴리즈 레버부(160)가 시계방향으로 회전되고, 릴리즈 레버부(160)의 롤러부(162)가 스페이서부(168)에 걸리면 릴리즈 레버부(160)의 시계방향 회전이 정지된다. 또한, 릴리즈 레버부(160)가 시계방향으로 회전됨에 따라 제1 릴리즈 가압부(164)와 함께 파울 보스부(172)가 시계방향으로 회전되므로, 파울부(170)가 시계방향으로 회전된다. 또한, 제2 릴리즈 가압부(166)가 하측으로 이동되면서 클로징 레버부(180)의 구속을 해제하므로, 클로징 레버부(180)가 탄성부재의 탄성력에 의해 반시계방향으로 회전됨에 의해 인입홀부(112)의 타측을 폐쇄시킨다.As the sector cam unit 140 rotates in a clockwise direction, the first sector pressing unit 144 is spaced apart from the roller unit 162 of the release lever unit 160. At this time, the release lever unit 160 is rotated in a clockwise direction, and when the roller unit 162 of the release lever unit 160 is caught by the spacer unit 168, the clockwise rotation of the release lever unit 160 is stopped. In addition, as the release lever unit 160 is rotated in a clockwise direction, the foul boss unit 172 together with the first release pressing unit 164 is rotated in a clockwise direction, so that the foul unit 170 is rotated in a clockwise direction. In addition, since the second release pressing unit 166 is moved downward to release the restraint of the closing lever unit 180, the closing lever unit 180 is rotated counterclockwise by the elastic force of the elastic member, so that the inlet hole ( 112), the other side is closed.
섹터캠부(140)가 시계방향으로 더욱 회전됨에 따라 제2 섹터 가압부(145)가 클라우 보스부(152)를 시계방향으로 더욱 회전시키면, 클라우부(150)가 시계방향으로 회전된다. 클라우부(150)가 시계방향으로 회전됨에 따라 클라우 구속부(154)가 인입홀부(112)의 타측을 폐쇄시킨다. 이때, 테일게이트가 완전히 닫히지 않은 경우도 클라우 구속부(154)가 모터부(122)의 구동력에 의해 스트라이커(10)를 가압하여 인입홀부(112)의 중심부로 이동시키므로, 테일게이트가 불완전하게 닫혔을 때에 테일게이트를 완전히 닫아주는 신칭(chinching) 기능도 수행한다. 따라서, 신칭 기능을 수행할 수 있도록 신칭용 모터장치를 설치하지 않아도 되므로, 차량의 제조 비용을 감소시킬 수 있다.As the sector cam part 140 is further rotated in the clockwise direction, when the second sector pressing part 145 further rotates the claw boss part 152 in the clockwise direction, the claw part 150 is rotated in the clockwise direction. As the claw part 150 is rotated in the clockwise direction, the claw restraining part 154 closes the other side of the inlet hole part 112. At this time, even when the tailgate is not completely closed, the claw restraint unit 154 presses the striker 10 by the driving force of the motor unit 122 and moves it to the center of the inlet hole 112, so that the tailgate is incompletely closed. It also performs a chinching function that completely closes the tailgate when closed. Therefore, since it is not necessary to install a new motor device to perform the new model function, it is possible to reduce the manufacturing cost of the vehicle.
클라우부(150)가 인입홀부(112)의 일측을 폐쇄하고, 클로징 레버부(180)가 인입홀부(112)의 타측을 폐쇄하므로, 스트라이커(10)가 인입홀부(112)의 양측으로 이동되는 것을 방지할 수 있다. 따라서, 테일게이트가 닫힌 상태를 유지하게 된다. Since the cloud portion 150 closes one side of the inlet hole 112 and the closing lever portion 180 closes the other side of the inlet hole 112, the striker 10 is moved to both sides of the inlet hole 112 Can be prevented. Thus, the tailgate remains closed.
다음으로, 비상시 사용자가 테일게이트를 개방하는 과정에 관해 설명하기로 한다.Next, the process of opening the tailgate by the user in case of an emergency will be described.
도 17은 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치에서 케이블 레버부가 케이블에 의해 시계방향으로 회전되는 상태를 도시한 평면도이고, 도 18은 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치에서 파울부와 클라우부는 케이블 레버부에 의해 반시계방향으로 회전되는 상태를 도시한 평면도이고, 도 19는 본 발명의 일 실시예에 따른 차량용 테일게이트의 레치장치에서 클라우부가 인입홀부의 일측을 개방하고 클로징 레버부가 인입홀부의 타측을 폐쇄한 상태를 도시한 평면도이다.17 is a plan view showing a state in which a cable lever part is rotated in a clockwise direction by a cable in a latch device for a tailgate for a vehicle according to an embodiment of the present invention, and FIG. 18 is a tailgate for a vehicle according to an embodiment of the present invention Is a plan view showing a state in which the foul part and the claw part are rotated in a counterclockwise direction by a cable lever part, and FIG. 19 is a claw part in the latch device of a tailgate for a vehicle according to an embodiment of the present invention. It is a plan view showing a state in which one side is opened and the other side of the closing lever part is closed.
도 17 내지 도 19를 참조하면, 케이블(194)이 당겨지면, 케이블 레버부(190)가 시계방향으로 당겨진다. 케이블 레버부(190)의 상측이 파울부(170)를 가압하여 반시계방향으로 회전시키면, 파울부(170)가 클라우부(150)의 지지력을 해제한다. 클라우부(150)의 반시계방향 구속이 해제되므로, 클라우부(150)가 탄성부재의 탄성력에 의해 반시계방향으로 회전된다. 이때, 클라우부(150)의 클라우 구속부(154)가 인입홀부(112)의 일측을 개방시킨다. 17 to 19, when the cable 194 is pulled, the cable lever unit 190 is pulled in the clockwise direction. When the upper side of the cable lever part 190 presses the foul part 170 and rotates it counterclockwise, the foul part 170 releases the supporting force of the claw part 150. Since the anticlockwise restraint of the claw part 150 is released, the claw part 150 is rotated counterclockwise by the elastic force of the elastic member. At this time, the claw restraining part 154 of the claw part 150 opens one side of the inlet hole part 112.
본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 발명의 진정한 기술적 보호범위는 청구범위에 의해서 정하여져야 할 것이다.Although the present invention has been described with reference to the embodiments shown in the drawings, this is only illustrative, and those of ordinary skill in the field to which the technology pertains, various modifications and other equivalent embodiments are possible. I will understand. Therefore, the true technical protection scope of the present invention should be determined by the claims.
