이러한 센서부(110)는 도시된 바와 같이, 도어(10)에 일체로 형성되어 있는 사이드 미러(20)의 소정부분에 구비되어 있어서 도어의 전방에 장애물 존재 여부를 탐지하게 된다. 상기 센서부(110)로는 초음파 센서부를 사용하는 것이 바람직할 것이며, 이러한 초음파 센서부는 범퍼 후방의 장애물 탐지 등에 이용되고 있으므로 이에 관한 상세한 설명은 생략한다.As shown in the drawing, the sensor unit 110 is provided at a predetermined portion of the side mirror 20 which is integrally formed in the door 10 to detect the presence of an obstacle in front of the door. It is preferable to use an ultrasonic sensor unit as the sensor unit 110. Since the ultrasonic sensor unit is used for detecting an obstacle behind the bumper, a detailed description thereof will be omitted.

도 2는 본 발명에 따른 도어 체커의 사시도이다.2 is a perspective view of a door checker according to the present invention.

일반적인 도어체커는 차체 측에 부착된 힌지부(50)에 체커암(120)이 회동 가능하도록 고정되어 있고, 상기 체커암(120)이 도어 측에 부착된 플레이트(60)를 통과하도록 되어 있으며, 상기 플레이트의 좌측(도어의 내부)에 탄성부재(70)를 구비하고, 체커암에 돌출부(122)를 구비하여, 상기 탄성부재(70)가 돌출부(122)를 잡아주도록 함으로써 도어 개방시 절도감을 부여하는 기능을 수행하게 된다.The general door checker is fixed to the hinge portion 50 attached to the vehicle body side so that the checker arm 120 is rotatable, the checker arm 120 is to pass through the plate 60 attached to the door side, The elastic member 70 is provided on the left side of the plate (inside of the door), and the protrusion 122 is provided on the checker arm, so that the elastic member 70 holds the protrusion 122 so that the door can be cut off when the door is opened. It will perform the function of granting.

본 발명은 이러한 종래의 도어체커에 있어서, 돌출부가 형성되지 않는 측면부(124)를 밀착하여, 체커암(120)의 움직임을 고정할 수 있도록 하는 체커암고정장치(130)를 더 구비하게 된다. 따라서 상기 체커암고정장치(130)를 동작시킴으로써 도어의 개방도중 원하는 위치에서 도어가 더 이상 개방되지 않도록 할 수 있다.In the conventional door checker, the checker arm fixing device 130 may be further provided to closely contact the side portion 124 where the protrusion is not formed, thereby fixing the movement of the checker arm 120. Accordingly, by operating the checker arm fixing device 130, the door may no longer be opened at a desired position during the opening of the door.

이러한 체커암고정장치(130)는 도 1에서 설명한 센서부(110)의 신호를 받아 도어를 고정하게 된다.The checker arm fixing device 130 receives the signal of the sensor unit 110 described with reference to FIG. 1 to fix the door.

도 3은 본 발명에 따른 도어 체커의 제어 흐름도이다.3 is a control flowchart of a door checker according to the present invention.

도시된 바와 같이, 도어의 개방이 시작(301)되면 도 1에서 설명한 센서부(110)가 작동하여 장애물 존재여부를 탐지하고(302), 장애물이 발견되면 체커암을 잠그고(303), 장애물이 발견되지 않으면 다시 장애물 존재여부를 탐지하게 된다.As shown, when the opening of the door is started 301, the sensor unit 110 described in Figure 1 operates to detect the presence of obstacles (302), if an obstacle is found locks the checker arm (303), the obstacle is If not found, the presence of obstacles is detected again.

체커암을 잠그게 되면(303) 도어가 더 이상 개방되지 않아 탑승자가 장애물 존재를 인식 할 수 있게 된다. 체커암의 잠금을 해제하는 것(304)은 체커암이 잠긴 후 소정시간 경과후 저절로 이루어지게 하거나, 탑승자가 인사이드 도어핸들을 당기면 해제 되도록 하는 것이 바람직하다. 탑승자가 장애물 존재를 인식한 후 체커암의 잠금이 해제되어 도어를 닫으면 종료된다.When the checker arm is locked (303), the door is no longer open, allowing the occupant to recognize the presence of an obstacle. Unlocking the checker arm 304 may be made on its own after a predetermined time elapses after the checker arm is locked, or when the occupant pulls the inside door handle. After the occupant recognizes the presence of an obstacle, the checker arm is unlocked to close the door.

도 4a 및 4b는 본 발명에 따른 도어체커의 체커암 고정장치의 구조를 나타낸개념도이다.4a and 4b is a conceptual diagram showing the structure of a checker arm fixing device of the door checker according to the present invention.

본 발명에 따른 체커암잠금장치(130)는 체커암의 측면부(124)를 밀착하여 체커암(120)이 움직이지 않도록 고정하는 역할을 수행하는 것으로, 도시된 바와 같이, 상하로 작동할 수 있는 작동편(135), 상기 작동편(135)의 양 측면에 구비된 전자석(132), 상기 작동편(135)을 체커암(120)으로 부터 끌어올리는 탄성부재(138)로 이루어진다.The checker arm locking device 130 according to the present invention serves to fix the checker arm 120 so as not to move by bringing the side portion 124 of the checker arm into close contact with each other. It consists of an operating piece 135, an electromagnet 132 provided on both sides of the operating piece 135, the elastic member 138 to pull the operating piece 135 from the checker arm 120.

도 5a는 전자석에 전류가 흐르지 않는 평상시의 상태를 나타내고 있는 것으로 탄성부재(138)의 탄성력으로 인하여 작동편(135)이 체커암(120)으로부터 이격된 상태를 유지하고 있다. 센서부(도 1의 110)에 장애물이 감지되어 전자석(132)에 전류가 흐르게 되면 상기 전자석(132)의 주위에 전자기장이 형성되고, 따라서 상기 작동편(135)은 페러데이 법칙에 의하여 체커암의 측면부(124)에 밀착되는 방향으로 이동하려는 힘을 받게 되어, 도 5b에 도시된 바와 같이 체커암의 측면(124)에 밀착되어 체커암(120)이 더 이상 이동하지 못하도록 고정하게 된다. 이러한 작동이 원활하게 이루어지기 위해서는 전자기장에 의해서 작동편(135)에 가해지는 힘이, 상기 탄성부재(138)가 작동편(135)을 끌어올리려는 힘보다 커야 한다.5A illustrates a normal state in which no electric current flows through the electromagnet, and the operating piece 135 is kept spaced apart from the checker arm 120 due to the elastic force of the elastic member 138. When an obstacle is sensed by the sensor unit 110 (FIG. 1) and an electric current flows through the electromagnet 132, an electromagnetic field is formed around the electromagnet 132. The force to move in the direction in close contact with the side portion 124, as shown in Figure 5b is in close contact with the side of the checker arm 124 is fixed to prevent the movement of the checker arm 120 any more. In order for this operation to be performed smoothly, the force applied to the operating piece 135 by the electromagnetic field must be greater than the force of the elastic member 138 to raise the operating piece 135.

도 3에서 설명한 바와 같이 체커암의 잠금 해제 조건이 되면, 전자석(132)에 흐르던 전류가 차단되고, 작동편(135)은 탄성부재에 저장된 탄성력에 의하여 원복하게 되어 도어를 닫을 수 있게 된다.As described with reference to FIG. 3, when the checker arm is in the unlocking condition, the current flowing in the electromagnet 132 is cut off, and the operation piece 135 is restored by the elastic force stored in the elastic member to close the door.

상기 작동편(135)은 전자기장 내에서 전자기력에 의하여 운동하는 아마추어(135)와, 상기 아마추어(135) 하부에 부착되어 체커암의 측면부(124)와 직접 접촉하는 마찰부재(136)로 이루어지고, 상기 마찰부재(136)는 내마모성이 우수한 재질로 제작됨이 바람직하다.The operating piece 135 is composed of an armature 135 to move by the electromagnetic force in the electromagnetic field, and a friction member 136 attached to the lower portion of the armature 135 and in direct contact with the side portion 124 of the checker arm, The friction member 136 is preferably made of a material having excellent wear resistance.

작동편(135)이 체커암(120)을 고정하는 것은 상기 마찰부재(136)와 체커암 측면부(124)의 마찰력에 의해서 이므로, 체커암(120)을 고정하는 힘을 증가시키기 위해서는 도시된 바와 같이 마찰부재(136)와 체커암의 측면부(124)에 모두 요철을 구비하도록 하여 상기 요철이 맞물릴 수 있도록 하면 더욱 바람직하다.Since the actuating piece 135 fixes the checker arm 120 by the frictional force of the friction member 136 and the checker arm side portion 124, the increasing force for fixing the checker arm 120 is shown in FIG. As described above, it is more preferable that both of the friction member 136 and the side portion 124 of the checker arm have irregularities so that the irregularities can be engaged.

이상 설명한 바와 같이, 본 발명에 따른 도어 체커는 도어의 작동범위 내에 장애물 존재여부를 감지하는 센서부와 상기 센서부의 감지에 의해 체커암을 고정하는 체커암 고정장치를 구비하여, 도어의 개방시 도어의 작동반경 내에 장애물이 감지되면, 도어체커를 일시적으로 고정하도록 함으로써, 도어 개방시에 자주 발생하는 도어부의 손상을 근본적으로 해결하는 효과가 있다.As described above, the door checker according to the present invention includes a sensor unit for detecting the presence of obstacles within the operating range of the door and a checker arm fixing device for fixing the checker arm by the detection of the sensor unit. When an obstacle is detected within an operating radius of the door checker, the door checker is temporarily fixed, thereby fundamentally eliminating damage to the door part frequently occurring when the door is opened.
