Description

차량 밀림 방지장치Vehicle anti-skid device
본 발명은 경사로에 차량이 주정차한 경우에 차량의 밀림을 방지하기 위한 차량 밀림 방지장치에 관한 것이다.The present invention relates to a vehicle rolling prevention device for preventing the vehicle from rolling when the vehicle is parked on a slope.
일반적으로 차량이 경사로에서 밀림을 방지하기 위해, 프로펠러연장수단에 브레이크밴드를 장착한 제동장치를 신설하여 운전자가 탑승하지 않은 차량의 밀림을 방지하도록 된 밀림방지장치가 종래에 공개된 바 있다. 보통의 경우 운전자가 경사로에 차량을 주차할 경우에, 차량의 밀림을 방지하기 위해 수동변속기의 경우 등판로 상의 주차시에는 1단을, 강판로 주차시에는 후진기어에 위치시키고 난 후 파킹브레이크를 작동시키고, 자동변속기의 경우 P레인지에 위치시킨 후 파킹브레이크를 작동시키게 된다. 이 때 운전자의 부주의로 N 레인지상태에서 파킹브레이크를 작동하지 않은 상태로 주차하는 경우가 종종 발생하는데, 경사가 급박할 때에는 차량의 움직임이 초기에 발생되므로 운전자가 쉽게 조치를 취할 수 있지만, 완만한 경사로에서는 타이어의 마찰력으로 인해 차량의 움직임이 서서히 일어나므로 운전자는 이를 인지하지 못하고 그대로 방치하게 될 수 있다. 이러한 경우 외부의 조그만 충격에도 차량이 움직이게 되어 주위의 차량과의 접촉사고 및 주변의 인명피해를 유발하는 경우가 발생될 수 있다.In general, in order to prevent a vehicle from being pushed on a slope, a braking device having a brake band mounted on a propeller extension means is newly installed to prevent a vehicle from being pushed by a driver in which the driver is not riding. In general, when the driver parks the vehicle on an incline, in order to prevent the vehicle from rolling, in the case of a manual transmission, place the first gear when parking on an incline and reverse gear when parking on a steel plate, and then apply the parking brake. In the case of an automatic transmission, after placing it in the P range, the parking brake is operated. At this time, the driver's carelessness often occurs when parking in the N-range state without the parking brake applied. On an incline, the vehicle's movement gradually occurs due to the friction force of the tire, so the driver may leave it as it is without recognizing it. In this case, even a small external shock may cause the vehicle to move, causing a contact accident with a nearby vehicle and damage to people around it.
따라서, 제동력을 차량의 외부에서 타이어에 직접 가하면서 지면과의 마찰로 인한 정지상태를 유지시킬 수 있는 장치가 요구된다.Accordingly, there is a need for a device capable of maintaining a stationary state due to friction with the ground while directly applying a braking force to the tire from the outside of the vehicle.

도 1 내지 도 2를 참조하면, 밀림방지장치는 차량(1)의 저면에 배치될 수 있다. 상기 저면은 바람직하게는 차륜(1a)의 전후측일 수 있다. 전륜의 전방인 행오버에는 범퍼가 주로 위치되므로, 전륜과 후륜의 사이인 휠베이스 구간에 배치될 수 있으며, 전륜 쪽 또는 후륜 쪽에 선택적으로 배치될 수도 있고 또는 전후 양쪽에 다 배치될 수도 있다.1 to 2 , the anti-skid device may be disposed on the bottom of the vehicle 1 . The bottom surface may preferably be the front and rear sides of the wheel 1a. Since the bumper is mainly located in the hangover in front of the front wheel, it may be disposed in the wheelbase section between the front wheel and the rear wheel, may be selectively disposed on the front wheel side or the rear wheel side, or may be disposed on both front and rear wheels.
즉, 도시된 바와 같이 후륜에 배치되는 경우에도, 후륜의 전측인 휠베이스 구간에 마련될 수 있다. 물론, 차량(1) 형태의 일 예로서 도 1에 도시된 차량(1)을 표시하였으나 차량(1)의 형태 및 구조에 따라 차량(1)의 저면에 자유롭게 배치될 수가 있다. 그럼에도 불구하고 본 발명의 일 실시예인 밀림방지장치는 차륜(1a)과 근접한 위치에 배치될 수 있다.That is, even when it is disposed on the rear wheel as illustrated, it may be provided in the wheelbase section which is the front side of the rear wheel. Of course, although the vehicle 1 shown in FIG. 1 is shown as an example of the shape of the vehicle 1 , it may be freely disposed on the bottom surface of the vehicle 1 according to the shape and structure of the vehicle 1 . Nevertheless, the anti-skid device according to an embodiment of the present invention may be disposed at a position close to the wheel 1a.
전술한 바와 같이 밀림방지장치는 차륜(1a)을 가압함으로써 지면(G)으로부터 차륜(1a)이 비회전된 상태가 유지되도록 한다. 이는 종래의 네거티브 브레이크나 전자식 브레이크와 구조 및 메커니즘 상으로 차이가 있으며, 차륜(1a)에 직접 접촉함으로써 차륜(1a)을 정지시키는 특징을 구현할 수 있다.As described above, the anti-skid device maintains the non-rotated state of the wheel 1a from the ground G by pressing the wheel 1a. This is different from the conventional negative brake or electromagnetic brake in structure and mechanism, and may implement a feature of stopping the wheel 1a by directly contacting the wheel 1a.

도 3을 참조하면, 밀림방지장치는 연결부(110), 회동부(120) 및 슬라이더(130)를 포함한다. 구체적으로 밀림방지장치는 차량(1)의 일측에 연결되는 연결부(110), 연결부(110)와 회동이 가능하도록 연결되고 일측이 개방된 중공형의 하우징(121) 및 하우징(121)의 내측에 개방측을 향해 피스톤로드와 같은 연장로드(S)를 직선방향으로 인출 및 인입시키는 실리더와 같은 연장수단(125)을 포함하는 회동부(120) 및 연장수단(125)의 구동에 의한 연장로드(S)의 인입으로 회동부(120) 내측으로 슬라이드되는 바디(131) 및 연장수단(125)의 구동에 의한 연장로드(S)의 인출로 차량(1)의 차륜(1a)이 비회전되도록 가압하는 논슬립패드(135)를 더 포함하는 연장로드(S)의 슬라이더(130)를 포함한다.Referring to FIG. 3 , the anti-skid device includes a connection part 110 , a rotation part 120 , and a slider 130 . Specifically, the anti-skid device is connected to the connection part 110 connected to one side of the vehicle 1, the connection part 110 and the hollow housing 121 with one side open and connected to the inside of the housing 121. Extension rod by driving of the rotating part 120 and the extension means 125 including an extension means 125 such as a cylinder for withdrawing and retracting the extension rod S such as a piston rod in a straight direction toward the open side So that the wheel 1a of the vehicle 1 is non-rotated by the withdrawal of the extension rod S by the driving of the body 131 and the extension means 125 that slide into the rotating part 120 due to the inlet of (S). It includes a slider 130 of the extension rod (S) further comprising a non-slip pad 135 to press.
본 실시예에는 연장수단(125)과 연장로드(S)가 실린더와 피스톤로드로 구성된 것을 도시하고 설명하였으며, 이는 운전석 등에 컨트롤러를 연동하여 연장로드(S)를 쉽게 인출 또는 인입 작동시킬 수 있으며, 연장수단(125)과 연장로드(S)를 댐퍼(미도시)로 구성하여 수동으로 연장되는 댐퍼로드로 실시예를 변형할 수 있으며 본 발명에서 이와 자세한 설명은 생략토록 한다.In this embodiment, the extension means 125 and the extension rod (S) are illustrated and described as consisting of a cylinder and a piston rod, which can be easily drawn out or drawn in by linking the controller to the driver's seat or the like, By configuring the extension means 125 and the extension rod S with a damper (not shown), the embodiment can be modified with a damper rod extending manually, and detailed description thereof will be omitted in the present invention.
그리고, 연결부(110)의 플레이트(111)는 차량(1)의 저면에 고정되기 위한 고정구(110a)가 마련된다. 상기 고정구(110a)에는 패스너와 같은 수단을 통해 연결부(110)가 차량(1)의 저부와 결합될 수 있도록 한다. 여기서 차량(1)의 저부와 결합됨은 직접적으로 결합되는 것을 의미하기도 하나, 별도의 어댑터(미도시)를 통해 결합되는 것일 수 있다. 따라서, 어댑터나 차량(1)의 저면에 따라 결합구조는 다양하게 적용될 수 있다.In addition, the plate 111 of the connection part 110 is provided with a fixture 110a for being fixed to the bottom surface of the vehicle 1 . The fastener 110a has the connection part 110 to be coupled to the bottom of the vehicle 1 through means such as a fastener. Here, coupling with the bottom of the vehicle 1 may mean being directly coupled, but may be coupled through a separate adapter (not shown). Accordingly, the coupling structure may be variously applied depending on the adapter or the bottom surface of the vehicle 1 .
또한, 연결부(110)는 플레이트(111)로부터 힌지(112a)가 마련된 브라켓(112)이 돌출될 수 있다. 여기서 힌지(112a)란, 핀(미도시)이 삽입가능하고 핀의 양단이 자유회전이 가능하도록 지지되는 통공을 의미한다. 따라서, 브라켓(112)은 핀의 양단이 지지될 수 있도록 한 쌍이 마련될 수 있다.In addition, as for the connection part 110 , a bracket 112 provided with a hinge 112a may protrude from the plate 111 . Here, the hinge 112a refers to a through hole through which a pin (not shown) can be inserted and both ends of the pin are supported so as to be freely rotatable. Accordingly, a pair of brackets 112 may be provided so that both ends of the pin can be supported.
한편, 브라켓(112)을 통해 연결부(110)는 회동부(120)와 결합될 수 있다. 회동부(120)는 중공형으로 형성된 하우징(121)의 일단에 상기 힌지(112a)와 동축상에 배치되어 핀으로 연결될 수 있는 한 쌍의 핀삽입공(121a)이 형성된다. 핀삽입공(121a)의 외측에 브라켓(112)이 각각 배치되고, 힌지(112a)와 핀삽입공(121a)이 동축상에 위치된 상태에서 핀이 삽입될 수 있다. 이 때, 삽입되는 핀은 하우징(121) 내에 배치되는 연장수단(125)과 연결될 수도 있고, 연장수단(125)과 별개로 구성될 수도 있다. Meanwhile, the connection part 110 may be coupled to the rotation part 120 through the bracket 112 . A pair of pin insertion holes 121a which are disposed coaxially with the hinge 112a and can be connected by pins are formed at one end of the rotating part 120 in the hollow housing 121 . Brackets 112 are respectively disposed on the outside of the pin insertion hole 121a, and the pin may be inserted in a state in which the hinge 112a and the pin insertion hole 121a are located on the same axis. At this time, the inserted pin may be connected to the extension means 125 disposed in the housing 121 or may be configured separately from the extension means 125 .
구체적으로는, 연장수단(125)의 단부에 마련된 헤드(125a)의 연결공(125b)을 핀이 관통하면서 연결될 수 있다. 즉, 핀은 브라켓(112), 하우징(121) 및 연장수단(125)을 연결시킬 수 있다. 이와 같이 연결된 연결부(110) 및 회동부(120)는 핀을 중심으로 회동될 수 있다.Specifically, the pin may be connected while passing through the connection hole 125b of the head 125a provided at the end of the extension means 125 . That is, the pin may connect the bracket 112 , the housing 121 and the extension means 125 . The connecting unit 110 and the rotating unit 120 connected in this way may be rotated around the pin.
중공형으로 형성된 하우징(121)은 일측이 개방될 수 있다. 개방측으로 삽입되는 슬라이더(130)의 외주연은 하우징(121)의 내주연과 슬라이드되며 이동될 수 있다. 따라서, 핀삽입공(121a)을 중심으로 회동되는 회동부(120)를 따라 회동궤적을 그리며 함께 회동될 수 있다. 여기서, 회동동력은 연결부(110)에 마련된 모터(115)에 의한 것일 수 있다. 상기 모터(115)는 연결부(110)의 저면측에 결합되어, 와이어(116a)를 통해 연장수단(125)의 견인여부를 결정함으로써 회동동력을 제공할 수 있다. 구체적으로 모터(115)는 모터(115)축에 마련된 풀리(116), 풀리(116)에 권취된 와이어(116a) 및 와이어(116a)의 단부에 형성된 고정부(116b)를 포함할 수 있다.One side of the housing 121 formed in a hollow shape may be opened. The outer periphery of the slider 130 inserted into the open side may slide and move with the inner periphery of the housing 121 . Therefore, it can be rotated together while drawing a rotational trajectory along the rotational portion 120 that is rotated around the pin insertion hole (121a). Here, the rotational power may be due to the motor 115 provided in the connection part 110 . The motor 115 may be coupled to the bottom side of the connection unit 110 and provide rotational driving force by determining whether to pull the extension means 125 through the wire 116a. Specifically, the motor 115 may include a pulley 116 provided on the motor 115 shaft, a wire 116a wound around the pulley 116 , and a fixing part 116b formed at an end of the wire 116a.
여기서 와이어(116a)는 일단이 풀리(116)에 고정되고, 타단은 고정부(116b)에 의해 회동부(120)측과 고정될 수 있다. 즉, 모터(115)의 권취여부에 의해 상기 고정부(116b)와 고정된 회동부(120)가 견인되면서 핀삽입공(121a)을 중심으로 회동될 수 있다. 여기서 모터(115)가 와이어(116a)를 최대권취한 상태에서는 플레이트(111)와 하우징(121)이 인접하게 배치될 수 있다. 따라서, 플레이트(111)의 저면에 배치된 모터(115)가 회동궤적에 미간섭되기 위해 회동부(120)는 회동과정에서 모터(115)에 대응되는 위치에 모터인입공(120a)이 개구될 수 있다.Here, one end of the wire 116a may be fixed to the pulley 116 , and the other end may be fixed to the rotating unit 120 side by a fixing unit 116b. That is, the fixed part 116b and the fixed rotating part 120 are pulled by whether the motor 115 is wound or not, and can be rotated around the pin insertion hole 121a. Here, the plate 111 and the housing 121 may be disposed adjacent to each other in a state in which the motor 115 has the wire 116a fully wound. Therefore, in order for the motor 115 disposed on the bottom surface of the plate 111 to not interfere with the rotation trajectory, the rotation unit 120 has a motor inlet hole 120a at a position corresponding to the motor 115 in the rotation process. can
상기 모터인입공(120a)에 의해 회동부(120)는 플레이트(111)와 인접하게 접근할 수 있다. 접근과정에서 회동부(120)는 플레이트(111)와 충돌될 수도 있다. 따라서, 소정의 복원력을 지닌 완충패드(113)를 플레이트(111) 상의 충돌지점에 선택적으로 배치시킴으로써, 발생가능성이 있는 충격을 완화할 수 있다.The rotating part 120 can approach the plate 111 by the motor inlet hole 120a. In the process of approaching, the rotating part 120 may collide with the plate 111 . Therefore, by selectively arranging the buffer pad 113 having a predetermined restoring force at the collision point on the plate 111, it is possible to alleviate the impact that may occur.
한편, 슬라이더(130)는 전술한 바와 같이 하우징(121) 내측으로 인입되고 인출될 수 있다. 여기서, 슬라이더(130)가 인입 및 인출되는 슬라이딩 과정에서 슬라이더(130)의 바디(131)가 모터(115)부와 간섭이 발생할 수 있으므로, 바디(131)에는 인입 및 인출이 되는 방향과 구간만큼 절개된 개방부(131a)가 형성될 수 있다. 이를 통해 모터(115)는 권취 및 역권취를 수행하는데 타 구성과의 간섭이 발생하지 않을 수 있다. 상기 개방부(131a)는 작동 순서에 따라 실시예로 도시된 바와 같이 일측이 개구된 홈으로 형성될 수도 있고, 또는 관통공 형태로 형성될 수도 있다.Meanwhile, the slider 130 may be drawn in and out of the housing 121 as described above. Here, since the body 131 of the slider 130 may interfere with the motor 115 during the sliding process in which the slider 130 is retracted and drawn out, the body 131 may be drawn in and out as much as the direction and section. A cut open portion 131a may be formed. Through this, the motor 115 performs winding and reverse winding, but interference with other components may not occur. The opening portion 131a may be formed as a groove having one side open as shown in the embodiment, or may be formed in the form of a through hole according to the operation sequence.
또한, 연장수단(125)은 연장로드(S)를 인출하거나 인입함으로써 슬라이더(130)가 하우징(121) 내에서 슬라이드 되는 움직임을 발생시킬 수 있다. 여기서, 인출은 바디(131)가 차륜(1a)측으로 접근할 수 있도록 하는 것으로 최종적으로는 논슬립패드(135)가 차륜(1a)을 가압하여 차륜(1a)의 회전을 방지할 수도 있고 또는 차륜(1a)을 가압함과 동시에 차륜(1a)과 접지면(G) 사이에 개재되도록 할 수도 있다. 여기서 가압력은 연장수단(125)의 연장로드(S)에 의한 가압력으로만 발생할 수도 있으나, 추가로 탄성적으로 발생될 수 있다. 구체적으로, 상기 탄성력을 발생시키는 탄성체(E)가 연장수단(125)에 의해 가압되고, 가압된 탄성체(E)는 탄성력을 바디(131)로 전달할 수 있다.In addition, the extension means 125 may cause the slider 130 to slide in the housing 121 by drawing out or retracting the extension rod S. Here, the withdrawal allows the body 131 to approach the wheel 1a side. Finally, the non-slip pad 135 presses the wheel 1a to prevent rotation of the wheel 1a or the wheel ( While pressing 1a), it may be interposed between the wheel 1a and the ground plane G at the same time. Here, the pressing force may be generated only by the pressing force by the extension rod S of the extension means 125, but may be additionally generated elastically. Specifically, the elastic body E generating the elastic force is pressed by the extension means 125 , and the pressed elastic body E may transmit the elastic force to the body 131 .
본 예시에서 탄성체(E)는 스프링일 수 있고, 스프링 형태의 탄성체(E)는 연장로드(S)의 연장방향을 따라 감긴 형태로 마련될 수 있다. 이러한 스프링을 연장로드(S)의 인출시에 가압하는 제1스토퍼(Sa)가 연장로드(S) 외주연의 일지점에서 확장 형성되고, 제1스토퍼(Sa)는 연장로드(S) 인출에 의해 탄성체(E)를 가압할 수 있다. 제1스토퍼(Sa)에 대해서는 이하에서 도 5를 통해 구체적으로 설명하기로 한다.In this example, the elastic body (E) may be a spring, and the spring-shaped elastic body (E) may be provided in a wound shape along the extension direction of the extension rod (S). A first stopper (Sa) that presses such a spring when the extension rod (S) is drawn out is formed to be expanded at a point on the outer periphery of the extension rod (S), and the first stopper (Sa) is used for drawing out the extension rod (S). By this, the elastic body E can be pressed. The first stopper Sa will be described in detail below with reference to FIG. 5 .
가압된 탄성체(E)는 바디(131)의 내주연으로부터 내측으로 연장된 격벽(131b)을 가압하여 논슬립패드(135)가 차륜(1a)과 접촉한 상태에서 탄성체(E)가 탄성력이 발생하는 상태로 유지할 수 있다. 즉, 탄성력은 논슬립패드(135)를 통해 차륜(1a)으로 전달되어 회전을 저지할 수 있고, 차륜(1a)이 비회전상태가 유지되는 차량(1)은 지면(G)으로부터 차륜(1a)과 지면(G)간의 마찰에 의해 위치를 유지할 수 있다.The pressurized elastic body E presses the partition wall 131b extending inward from the inner periphery of the body 131 so that the elastic body E generates an elastic force while the non-slip pad 135 is in contact with the wheel 1a. state can be maintained. That is, the elastic force is transmitted to the wheel 1a through the non-slip pad 135 to block the rotation, and the vehicle 1 in which the wheel 1a is maintained in a non-rotating state is transferred from the ground G to the wheel 1a. The position can be maintained by friction between and the ground (G).
나아가, 논슬립패드(135)는 차륜(1a)의 접지면(G)과 면접촉이 될 수 있도록 한다. 이는 논슬립패드(135)가 상기 접지면(G)과 대응되는 곡률로 형성될 수 있고, 이를 통해 면접촉상태로 접지면(G)과의 접촉이 될 수 있다. 따라서, 차량(1)에 장착되는 차륜(1a)의 사이즈와 대응되는 논슬립패드(135)가 적용될 수 있다. 물론, 이는 바람직한 실시예에 불과하며, 상기 곡률의 상이함에 의해 선접촉이 되더라도 비회전을 유지할 수는 있다. 또한, 논슬립패드(135)에 의한 접지면(G)의 가압시에 논슬립패드(135)와 차륜(1a)의 접지면(G) 간의 보다 효과적인 가압을 위해 논슬립패드(135)는 적어도 차륜(1a)과 접하는 면적은 마찰력이 높은 표면으로 마련될 수 있다.Furthermore, the non-slip pad 135 makes surface contact with the ground plane G of the wheel 1a. In this case, the non-slip pad 135 may be formed to have a curvature corresponding to the ground plane G, and thus may be in contact with the ground plane G in a surface contact state. Accordingly, the non-slip pad 135 corresponding to the size of the wheel 1a mounted on the vehicle 1 may be applied. Of course, this is only a preferred embodiment, and the non-rotation can be maintained even if the line contact is made due to the difference in the curvature. In addition, for more effective pressurization between the non-slip pad 135 and the ground plane G of the wheel 1a when the non-slip pad 135 presses the ground plane G, the non-slip pad 135 has at least the wheel 1a. ) and the area in contact with the surface may be provided with a high frictional force.

풀리(116)에서 와이어(116a)가 권출되도록 모터(115)가 회전하면 회동부(120) 및 바디(130)는 자중에 의해 하향되어 힌지(112a)를 기준으로 회동하게 되는데, 만약 힌지에 이물질에 부착되거나 또는 회동부(120) 및 바디(130)가 매우 가벼운 재질로 제작된 경우에 필요에 따라 회동부(120) 및 바디(130)를 하향되게 회동되도록 밀어줄 구성으로서 전개스프링(E2)을 더 구비할 수 있다.When the motor 115 rotates so that the wire 116a is unwound from the pulley 116, the rotating part 120 and the body 130 are downward by their own weight and rotate based on the hinge 112a. A deployment spring (E2) as a configuration that will push the rotating part 120 and the body 130 to rotate downward as necessary when attached to or when the rotating part 120 and the body 130 are made of a very light material may be further provided.
전개스프링(E2)은 토션스프링을 힌지(112a)에 결합되는 핀과 회동부(120)사이에 개재되도록 구성하여 모터(115)가 와이어(116a)를 권취하면 전개스프링(E2)은 가압되고, 반대로 모터(115)가 와이어(116a)를 권출하면 전개스프링(E2)은 탄성력이 회동부(120)로 작용하여 회동부(120)가 강제로 하향되게 회동하는 것이다.The deployment spring E2 is configured such that the torsion spring is interposed between the pin coupled to the hinge 112a and the rotating part 120 so that the motor 115 winds the wire 116a, the deployment spring E2 is pressed, Conversely, when the motor 115 unwinds the wire 116a, the elastic force of the unfolding spring E2 acts as the rotating unit 120 to forcibly rotate the rotating unit 120 downward.
도 4 및 도 5를 참조하면, 모터(115)의 권취량에 따라, 회동방향(R)으로의 회동각도는 달라질 수 있다. 따라서, 다소 차이가 날 수 있는 회동각도를 보상하기 위해 슬라이더(130)의 바디(131)에는 곡형의 장공(131c)이 마련될 수 있다. 논슬립패드(135)는 회동중심부(135a) 및 회동이동부(135b)를 통해 바디(131)와 연결될 수 있다. 구체적으로 회동중심부(135a)는 바디(131)의 연동공(131d)에 연결되고, 회동이동부(135b)는 상기 장공(131c)에 연결되어, 연동공(131d)을 중심으로 장공(131c)이 형성된 궤적을 따라 회동이동부(135b)가 회동될 수 있다.4 and 5 , depending on the amount of winding of the motor 115 , the rotation angle in the rotation direction R may vary. Accordingly, a curved long hole 131c may be provided in the body 131 of the slider 130 to compensate for a slightly different rotation angle. The non-slip pad 135 may be connected to the body 131 through the rotation center portion 135a and the rotation movement portion 135b.
