본 발명은 차량에 관한 것으로, 특히 차량의 회전시 시트를 평형으로 유지할 수 있도록 한 경사각 센서를 이용한 차량시트 자동 평형유지 장치에 관한 것이다.The present invention relates to a vehicle, and more particularly, to a vehicle seat automatic balancing device using an inclination angle sensor to keep the seat in balance during rotation of the vehicle.

일반적으로 경사각 센서를 이용하여 차량이 언덕길을 오르거나 내려올 때 시트가 평형을 유지하도록 하여 승차감을 더해 주도록 하고 있다.In general, the inclination angle sensor is used to add a ride comfort by maintaining the seat balance when the vehicle is going up or down the hill.

제1도는 이와 같은 경사각 센서의 원리를 설명하기 위한 도면으로, 수광소자(PTR1)(PTR2) 및 저항(R1)(R2)으로 직류브리지를 구성하고 그 불평형 전류검출회로에 직류계기 기구의 가동코일과 부하저항(R0)이 접속되어 있다.FIG. 1 is a view for explaining the principle of such an inclination angle sensor. A DC bridge is formed of light receiving elements PTR1, PTR2, and resistors R1, R2, and a movable coil of a DC instrument mechanism in its unbalanced current detection circuit. The overload resistor R0 is connected.

또한, 가동코일의 지침의 선단에 차광편(S)이 있고 센서가 지구 무게 중심에 대하여 CS 방향으로 고정되어 있을 때 차광편은 발광, 수광소자의 각각의 중심에 있고, 수광소자는 각각 등량인 광량을 받아서 브리지를 밸런스하고 있다.In addition, when the light shielding piece S is at the tip of the guide of the movable coil and the sensor is fixed in the CS direction with respect to the earth's center of gravity, the light shielding piece is at the center of each of the light emitting and light receiving elements, and the light receiving elements are each equivalent The bridge is balanced by receiving light.

센서가 지구무게중심에 대하여 θ1만큼 기울면, 가동소자도 같은 방향으로 기울지만 중량 불평형에 의한 모멘트 때문에 제2도와 같이 θ2만큼 원래의 방향으로 이동하면 차광편의 이동에 의해 수광소자(PRT1)(PRT2)의 저항이 변화하여 브리지의 밸런스가 깨어져 가동코일에 전류 l1이 흐른다.When the sensor is inclined by θ1 with respect to the earth's center of gravity, the movable element is also inclined in the same direction, but when the sensor moves in the original direction by θ2 as shown in FIG. The resistance of the bridge changes and the balance of the bridge is broken and current l 1 flows through the movable coil.

이 전류에 의하여 가동코일에는 차광중량에 의한 모멘트와는 반대방향의 토크를 일으켜 양자가 평행된 위치에서 멈추고, 이때의 전류 l1이 출력전류가 된다.This current causes the movable coil to generate torque in the opposite direction to the moment due to the light-shielding weight, and stops at a position where both are parallel to each other. At this time, the current l 1 becomes an output current.

여기서, 가동코일의 토크 T=KT1(K는 비례상수), 가동코일의 중량불평형에 의한 모멘트 M은 M=gℓ sin(θ1-θ2)가 되는데, 단 g는 차광편의 중량, ℓ은 가동부 중심에서 차광편까지의 거리가 된다.Here, the torque T = KT1 (K is the proportional constant) of the movable coil, and the moment M due to the weight unbalance of the movable coil is M = gℓ sin (θ1-θ2), provided that g is the weight of the light shielding piece and ℓ is the center of the movable part. It becomes the distance to the shading blade.

또한, 정지한 위치에서는 T=M이므로 Kl1=gℓ sin(θ1-θ2)At the stationary position, T = M, so Kl1 = gℓ sin (θ1-θ2)

∴ l 1=gℓ sin(θ1-θ2)/K∴ l 1 = gℓ sin (θ1-θ2) / K

가 된다.Becomes

실제로는 θ1θ2로 설계되어 있기 때문에 출력전류 l1은, l 1=gℓ sin θ1이 되고, 경사각의 sin에 비례한다. 따라서, θ1이 작을 때는 출력전류는 경사각에 비례한다.In fact, since it is designed as θ1θ2, the output current l1 becomes l 1 = gL sin θ1 and is proportional to the sin of the inclination angle. Therefore, when θ1 is small, the output current is proportional to the inclination angle.

종래에는 이와 같은 특성을 갖는 경사각 센서를 이용하여 차량이 언덕을 올라갈 때, 또는 내려올 때 시트가 자동적으로 이동되어 평형을 유지하도록 하였으나, 차량이 코너링을 회전할 경우에는 시트를 평형시켜 주지 못하게 되는 문제가 있었다.Conventionally, by using the inclination angle sensor having such characteristics, the seat is automatically moved to maintain equilibrium when the vehicle is going up or down a hill, but when the vehicle rotates the cornering, the seat is not balanced. There was.

본 발명은 이와 같은 종래의 결점을 해결하기 위하여 안출한 것으로, 차량이 코너링을 회전할 때에도 시트가 평형을 유지할 수 있도록 하는 경사각 센서를 이용한 차량시트 자동 평형유지 장치를 제공하는데 그 목적이 있다.The present invention has been made in view of the above-mentioned drawbacks, and an object of the present invention is to provide a vehicle seat automatic balancing device using an inclination angle sensor that enables the seat to be balanced even when the vehicle rotates cornering.

이하, 본 발명 경사각 센서를 이용한 차량시트 자동 평형유지 장치의 실시예를 첨부된 도면을 참고로 하여 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings an embodiment of the vehicle seat automatic balance maintaining apparatus using the present inclination angle sensor will be described.

제3도는 본 발명의 회로도로, 경사각을 감지하는 경사각 센서(10)와, 상기 경사각 센서(10)에 의해 감지된 경사각을 입력받아 제어신호를 출력시키는 제어부(20)와, 상기 제어부(20)의 제어에 의해 모터(M1-M4)를 구동시키도록 제어하는 제어부(20)와, 상기 모터(M1-M4)에 접속되어 모터(M1-M4)를 구동시키는 파워시트 스위치(30)로 구성된다.3 is a circuit diagram of the present invention, the inclination angle sensor 10 for detecting the inclination angle, the control unit 20 for receiving the inclination angle detected by the inclination angle sensor 10 to output a control signal, and the control unit 20 The control unit 20 controls to drive the motors M1-M4 under the control of the control unit, and a power seat switch 30 connected to the motors M1-M4 to drive the motors M1-M4. .

이와 같이 구성된 본 고안은 운전자가 수동적으로 시트의 평형을 유지시키고자 할 때, 예를 들어 차량이 언덕을 내려갈 때에는 운전자가 파워시트 스위치(30)를 조정하면 모터(M1)가 구동되어 시트의 앞부분이 올라가므로 시트가 평형을 유지하게 되고, 차량이 언덕을 올라갈 때에는 운전자가 파워시트 스위치(30)를 조정하면 모터(M2)가 구동되어 시트의 앞부분이 내려가므로 시트는 차량이 언덕을 오르거나 내리는 것에 관계없이 항상 평형을 유지하게 된다.According to the present invention configured as described above, the driver manually balances the seat, for example, when the driver descends the hill, when the driver adjusts the power seat switch 30, the motor M1 is driven to the front part of the seat. As this rises, the seat is in equilibrium, and when the vehicle is going up the hill, when the driver adjusts the power seat switch 30, the motor M2 is driven so that the front part of the seat goes down, so the seat is moved up or down the hill. It will always be in equilibrium regardless.

한편, 자동적으로 시트의 평형을 유지시키고자 할 때에는 경사각센서(10)에서 차량이 언덕을 오를 때와 내려갈 때의 경사각도를 감지하여 이를 제어부(20)로 보내면 제어부(20)에서 모터(M1)(M2)를 제어하여 시트의 평형을 유지시키게 된다.On the other hand, in order to automatically maintain the balance of the seat, the inclination angle sensor 10 detects the inclination angle when the vehicle is going up and down the hill and sends it to the control unit 20, the control unit 20 in the motor (M1) M2 is controlled to maintain the sheet equilibrium.

또한, 차량이 좌회전 할 때에는 경사각 센서(10)에서 이를 감지하여 제어부(20)에서 모터(M3)를 구동시키므로 시트의 우측이 내려가 시트가 평형을 유지하게 되고, 차량이 우회전할 때에는 제어부(20)에서 모터(M4)를 구동시켜 시트의 우측이 올라가 시트가 평형을 유지하게 된다.In addition, when the vehicle turns left, the inclination angle sensor 10 detects this and drives the motor M3 in the control unit 20 so that the right side of the seat is lowered to keep the seat in equilibrium, and when the vehicle turns right, the control unit 20 The motor M4 is driven to raise the right side of the seat to keep the seat in balance.

이와 같은 본 발명에 의하면, 차량이 언덕길을 오르거나 내려갈 때는 몰론 코너링시에도 자동적으로 시트의 수평이 유지되어 운행시 더욱 편의를 제공하게 되는 효과가 있다.According to the present invention, when the vehicle ascends or descends the hill road, even when cornering is automatically maintained the level of the seat has the effect of providing more convenience during operation.
