일반적으로 차체에는 각종 전기장치로부터 발생하는 정전기가 존재하며, 특히 춥고 건조한 날에는 더욱 심하게 발생된다. 이와같이 발생되는 정전기는 인체에 통전되었을 때 순간적인 쇼크를 유발하고, 공기중의 먼지를 흡착하여 차체의 부식을 촉진시키고, 카스테레오나 TV, 카폰 등의 음질을 불량하게 하는 노이즈를 발생시키며, CPU의 오작동에 따르는 연료의 불완전연소 및 유해가스의 배출량 증가 등과 같은 악영향을 초래하게 된다.In general, the vehicle body has static electricity generated from various electric devices, especially on cold and dry days. The static electricity generated in this way causes a momentary shock when the human body is energized, adsorbs dust in the air, promotes corrosion of the vehicle body, generates noise that deteriorates the sound quality of the car stereo, TV, and car phone. It causes adverse effects such as incomplete combustion of fuel and increased emissions of harmful gases due to malfunction.

종래에는 전술한 바와같이 악영향을 끼치는 정전기를 방지하기 위하여, 제 1 도에 도시된 바와 같이, 후방범퍼(31)의 소정부위에 홀(33)을 뚫고, 이 홀(33)에 접지선(32)을 결합수단(34)으로 고정한 후, 상기 접지선(32)을 도선(36)으로 차체(35)와 연결함으로써, 차체(35)에 존재하는 정전기를 지면으로 유도하였다. 그런데, 상기한 바와 같은 종래의 차량용 접지장치는 접지선(32)이 차체(35)에 고정결합되므로 차량운행시 지면에 닿아있는 접지선(32)이 쉽게 마모된다는 문제점이 있었다.Conventionally, in order to prevent static electricity from adverse effects as described above, as shown in FIG. 1, a hole 33 is drilled in a predetermined portion of the rear bumper 31, and the ground wire 32 is formed in the hole 33. After fixing to the coupling means 34, the ground wire 32 is connected to the vehicle body 35 by the conducting wire 36, thereby inducing static electricity present in the vehicle body 35 to the ground. However, the conventional vehicle grounding device as described above has a problem in that the ground wire 32 is fixedly coupled to the vehicle body 35 so that the ground wire 32 that is in contact with the ground is easily worn while driving the vehicle.

전술한 바와 같은 종래의 문제점을 해소하기 위하여 안출된 본 발명은 특히 자동변속기가 장착된 차량에 있어서, 차량운행시에는 접지선을 상승시켜 접지핀의 마모를 방지하고 차량정차시에는 접지선을 하강시켜 차체의 정전기를 지면으로 유도하려는 것이다.The present invention devised to solve the conventional problems as described above, particularly in a vehicle equipped with an automatic transmission, to raise the ground line when the vehicle is running to prevent wear of the ground pin and to lower the ground line when the vehicle is stopped To induce static electricity to the ground.

또, 도 3을 참조하면, 상기한 바와같이 변속레버(41)의 조작에 따라 셀렉트포지션스위치(40)가 검출하는 정차모드는 파킹(P), 중립(N)이고, 주행모드는 상기 파킹(P) 및 중립(N)을 제외한 후진(R), 주행(D), 2단(L2), 1단(L1)인 것은 통상적으로 알려진 바와 같다.Referring to FIG. 3, as described above, the stop mode detected by the select position switch 40 according to the operation of the shift lever 41 is parking (P) and neutral (N), and the driving mode is the parking ( Except for P) and neutral (N), the reverse (R), running (D), two-stage (L2), one-stage (L1) is generally known.

도 4는 본 발명의 실시예에 의한 차량의 측단면도로서, 전술한 모터(60)가 결합수단(34)에 의해서 후방범퍼(31)내에 고정장착되고, 상기 모터(60)의 회전축에 래크(71)가 결합되고, 상기 래크(71)에는 피니언(72)이 치합되고, 이 피니언(72)은 후방범퍼(31) 내부면에 상하방향으로 형성된 가이드(73)에 슬라이딩가능하도록 끼워결합되고, 상기 피니언(72)의 하단에 접지선(32)이 연결되며, 상기 접지선(32)과 전기적으로 도통되는 곳으로부터 차체(35)까지 도선(36)으로 연결된다.4 is a side cross-sectional view of a vehicle according to an embodiment of the present invention, in which the above-described motor 60 is fixedly mounted in the rear bumper 31 by a coupling means 34, and a rack ( 71 is engaged, the pinion 72 is engaged to the rack 71, the pinion 72 is fitted to slide to the guide 73 formed in the vertical direction on the inner surface of the rear bumper 31, A ground wire 32 is connected to a lower end of the pinion 72, and is connected to a conductor 36 from a place electrically connected to the ground wire 32 to the vehicle body 35.

도면의 미설명부호 S1 및 S2는 피니언(72)의 승강을 제한시키기 위한 리미트스위치이다.Reference numerals S1 and S2 in the drawings are limit switches for limiting the lift of the pinion 72.

이와같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

본 발명은 자동변속 차량에 있어서, 자동변속기의 변속레버(41)가 정차모드인 파킹(P), 중립(N)으로 조작되어 자동차가 정지되어 있는 상태에서는, 이를 전기신호로 검출하는 셀렉트포지션스위치(40)로부터의 신호에 따라 전자제어유닛(ECU)은 정차상태로 판별하게 된다. 또, 변속레버(41)가 후진(R), 주행(D), 2단(L2), 1단(L1)으로 세팅되어 자동차가 주행 또는 출발하려는 상태에서는, 다시 셀렉트포지션스위치(40)로부터의 검출신호에 따라 전자제어유닛(ECU)은 주행상태로 판별하게 된다.In the automatic transmission vehicle, the selector switch for detecting an electric signal when the transmission lever 41 of the automatic transmission is operated in the parking mode P and the neutral N in the stop mode and the vehicle is stopped. According to the signal from 40, the electronic control unit ECU determines to the stop state. In addition, when the shift lever 41 is set to the reverse (R), the travel (D), the second (L2), and the first (L1), and the vehicle is about to travel or start, the selector switch 40 According to the detection signal, the electronic control unit ECU determines the driving state.

이와같이 주행여부를 판별한 전자제어유닛(ECU)은 전류구동부(50)를 제어하여 정역의 전원전류를 출력하도록 하고, 이에 따라 모터(60)는 정역회전하게 되어 접지선(32)을 승하강시키게 된다.In this way, the electronic control unit (ECU) which determines whether the vehicle is driven controls the current driver 50 to output the power supply current in the forward and reverse directions, and accordingly, the motor 60 rotates forward and backward to raise and lower the ground wire 32. .

즉, 본 발명은 자동차가 정지한 상태에서는 변속레버(41)가 파킹(P) 또는 중립(N)상태의 정차모드로 조작된 상태이므로, 정차모드를 검출한 셀렉트포지션스위치(40)의 출력신호를 도입한 전자제어유닛(ECU)은 정차상태로 판별하여 전류구동부(50)를 제어하게 되고, 이에 따라 전류구동부(50)는 모터(60)로 정전류를 공급하게 되므로, 모터(60)가 정회전하여 래크(71)에 치합된 피니언(72)을 하강시키고, 이에 따라 접지선(32)이 하강하여 차체(35)의 정전기를 도선(36)과 접지선(32)을 통해 지면으로 유도하게 된다.That is, according to the present invention, since the shift lever 41 is operated in the stop mode of the parking (P) or neutral (N) state when the vehicle is stopped, the output signal of the select position switch 40 that detects the stop mode. The electronic control unit (ECU), which introduces the control unit, determines the stop state to control the current driving unit 50. Accordingly, the current driving unit 50 supplies the constant current to the motor 60, so that the motor 60 rotates. The pinion 72 engaged with the rack 71 is transferred to lower the ground wire 32, thereby lowering the ground wire 32 to guide the static electricity of the vehicle body 35 to the ground through the conductive wire 36 and the ground wire 32.

그리고, 자동차가 주행하는 상태에서는 변속레버(41)가 후진(R), 주행(D), 2단(L2), 1단(L1)상태의 주행모드로 조작된 상태이므로, 주행모드를 검출한 셀렉트포지션스위치(40)의 출력신호에 따라 전자제어유닛(ECU)에서는 주행상태를 판별하여 전류구동부(50)에서 모터(60)로 역전류를 공급하도록 하고, 이에 따라 모터(60)는 역회전되어 피니언(72)을 상승시킴으로써 지면에 닿아있던 접지선(32)이 상승되어 마모되지 않도록 한다.In addition, since the shift lever 41 is operated in the traveling mode of the reverse (R), the traveling (D), the second stage (L2), and the first stage (L1) in the state where the vehicle is traveling, the traveling mode is detected. According to the output signal of the select position switch 40, the electronic control unit (ECU) determines the driving state and supplies the reverse current from the current driver 50 to the motor 60, so that the motor 60 rotates in reverse. By raising the pinion 72, the ground wire 32, which has been in contact with the ground, is raised to prevent wear.

따라서, 탑승자는 접지선(32)이 하강한 후에 승하차하므로, 정전기에 의한 인체의 쇼크를 방지할 수 있고, 자동차가 주행중에는 접지선(32)이 승강되므로 접지선(32)의 손상을 방지한다.Therefore, the occupant gets on and off after the ground wire 32 is lowered, thereby preventing the human body from being shocked by static electricity, and preventing the damage of the ground wire 32 because the ground wire 32 is lifted while the vehicle is driving.

본 발명은 자동변속기가 장착된 차량에 있어서, 차체의 정전기를 지면으로 유도하는 접지선이 차량의 주행여부 즉, 변속레버 조작에 따라 승하강되도록 함으로써 주행마찰로 인해 발생하는 접지선의 마모를 방지하여 반영구적으로 사용할 수 있도록 하는 효과가 있다.According to the present invention, in a vehicle equipped with an automatic transmission, the ground wire for inducing static electricity of the vehicle body to the ground is raised and lowered according to whether the vehicle is driven, that is, the shift lever operation, thereby preventing wear of the ground wire caused by driving friction and semi-permanently. It can be used as an effect.
