Description

자동차의 주행방향변경에 따른 룸미러의 방향조정장치{Apparatus for Controlling Direction of Room Mirror According to Change in Driving Direction}Apparatus for Controlling Direction of Room Mirror According to Change in Driving Direction}

본 발명은 자동차의 주행방향변경에 따른 룸미러의 방향조정장치에 관한 것으로, 특히 자동차의 주행방향을 변경하기 위해 방향전환표시등을 조작한 후 스티어링휠(steering wheel)을 조작하면 스티어링휠의 조작 각도만큼 자동차의 내부에 설치된 룸미러의 방향을 조정하여 주행방향 전환에 따른 사각지대를 보정하기 위한 룸미러의 방향조정장치에 관한 것이다.The present invention relates to an apparatus for adjusting the direction of a room mirror according to a change in a driving direction of a vehicle, and in particular, to operate a steering wheel after operating a direction change indicator to change a driving direction of a vehicle. It relates to a room mirror direction adjusting device for correcting the blind spots in accordance with the change of the driving direction by adjusting the direction of the room mirror installed inside the vehicle.

자동차에는 사이드미러(side mirror)와 룸미러(room mirror)가 설치된다. 사이드미러는 운전석을 기준으로 자동차의 양측면에 설치되며 룸미러는 자동차의 내부에 설치된다. 자동차의 양측면에 설치된 사이드미러는 자동차의 양측면의 도로상황을 확인하기 위해 사용되며 룸미러는 자동차의 후방에 설치된 유리를 통해 자동차의 후방 도로상황을 확인하기 위해 사용된다.The car is equipped with a side mirror and a room mirror. Side mirrors are installed on both sides of the car based on the driver's seat and room mirrors are installed inside the car. Side mirrors installed on both sides of the car are used to check the road conditions on both sides of the car, and room mirrors are used to check the road conditions of the car through the glass installed on the rear of the car.

자동차의 주행방향을 방향을 전환시 운전자는 변경하고자 하는 방향에 설치된 사이드미러를 이용하여 도로상황을 확인하게 된다. 즉 오른쪽으로 주행방향을 변경하고자 하는 경우에는 운전자를 기준으로 운전자의 오른쪽에 설치된 사이드미러를 이용하고, 왼쪽으로 주행방향을 변경하고자 하는 경우에는 운전자를 기준으로 운전자의 왼쪽에 설치된 사이드미러를 이용하여 변경하고자 하는 방향의 도로상황을 감지하게 된다.When changing the driving direction of the vehicle, the driver checks the road situation by using a side mirror installed in the direction to be changed. In other words, if you want to change the driving direction to the right, use the side mirror installed on the right side of the driver, and if you want to change the driving direction to the left, use the side mirror installed on the left side of the driver. The road condition of the direction to change is detected.

주행방향을 변경하고자 하는 경우에 전술한 바와 같이 운전자는 변경하고자 하는 방향에 설치된 사이드미러를 이용하여 도로상황을 확인하게 된다. 사이드미러를 이용하여 도로상황을 감지 시 도로상태에 따라 사이드미러로 확인할 수 없는 공간이 발생된다. 즉, 사이드미러를 통해 볼 수 없는 공간이 형성되고 이 공간을 확인하지 못하는 사각지대가 발생된다. 사각지대가 발생되면 운전자는 자동차의 내부에 설치된 룸미러를 이용하여 확인할 수 있게 된다.When the driving direction is to be changed, as described above, the driver checks the road situation by using the side mirror installed in the direction to be changed. When the road mirror is detected using the side mirror, a space that cannot be identified by the side mirror is generated depending on the road condition. That is, a space that is not visible through the side mirror is formed, and a blind spot that does not identify this space is generated. When a blind spot occurs, the driver can check it using a room mirror installed inside the vehicle.

사각지대를 보정하기 위해 룸미러를 이용하는 경우에 룸미러는 단지 자동차의 후방에 설치된 유리를 통해 자동차의 후방 도로상황을 감지하도록 고정 설치됨으로 인해 사이드미러의 사각지대를 보다 효율적으로 보정할 수 없는 문제점이 있다.In the case of using the room mirror to correct the blind spot, the room mirror is fixed to detect the rear road situation of the car through the glass installed on the rear of the car. Therefore, the blind spot of the side mirror cannot be calibrated more efficiently. There is this.

본 발명의 목적은 자동차의 주행방향을 전환시키기 위해 방향전환표시등을 조작한 후 스티어링휠을 조작하면 스티어링휠의 조작각도를 감지하여 룸미러의 방향을 조정하기 위한 자동차의 주행방향변경에 따른 룸미러의 방향조정장치를 제공함에 있다.An object of the present invention is to operate the steering wheel after the operation of the turn indicator to change the driving direction of the vehicle, the room mirror according to the change of the driving direction of the vehicle to detect the operation angle of the steering wheel to adjust the direction of the room mirror To provide a direction adjusting device of.

본 발명의 다른 목적은 자동차의 주행방향전화에 따라 룸미러의 방향을 조정하여 사각지대를 보정할 수 있도록 함으로써 자동차의 주행방향에 변경에 따른 안전사고를 예방할 수 있도록 함에 있다.Another object of the present invention is to adjust the direction of the room mirror according to the driving direction of the vehicle to correct the blind spot to prevent a safety accident due to the change in the driving direction of the vehicle.

As shown in FIG. 3, the room mirror 3 is composed of a first room mirror 3a, a second room mirror 3b, and a third room mirror 3c, and the center third room mirror 3c is fixed. When the first room mirror 3a and the second room mirror 3b are assembled to rotate in a state, the rotary motor 31 and the rotating member 33 are attached to the first room mirror 3a and the second room mirror 3b. Install each one.

제1룸미러(3a)와 제2룸미러(3b)에 회전전동기(31)와 회전부재(33)가 각각 설치되는 경우에 제1룸미러(3a)와 제2룸미러(3b)의 회전방향을 각각 달리 구동시켜 운전자를 기준으로 운전자의 왼쪽 및 오른쪽 방향의 사각지대를 동시에 확인할 수 있도록 제1룸미러(3a)와 제2룸미러(3b)를 각각 회전시켜 구동할 수 있게 된다.Rotation of the first room mirror 3a and the second room mirror 3b when the rotary motor 31 and the rotating member 33 are installed in the first room mirror 3a and the second room mirror 3b, respectively. The first room mirror 3a and the second room mirror 3b may be rotated and driven so that the blind spots in the left and right directions of the driver can be simultaneously checked based on the driver by driving the directions differently.

이상과 같이 방향전환표시등과 스티어링휠의 조작각도를 이용하여 자동으로 룸미러의 방향을 조정함으로써 자동차의 주행방향변환에 따른 사각지대를 보정할 수 있게 된다.As described above, the blind spots can be corrected according to the change of driving direction of the vehicle by automatically adjusting the direction of the room mirror by using the direction change indicator and the steering angle of the steering wheel.

이상에서 설명한 바와 같이 본 발명은 자동차의 방향전환표시등과 스티어링휠의 조작각도를 감지하여 자동으로 룸미러의 방향을 조정함으로써 자동차의 주행방향변환에 따른 사각지대를 보정하여 주행방향변경에 따른 안전사고를 예방할 수 있는 효과를 제공한다.As described above, the present invention detects the operation angle of the steering wheel and the steering wheel of the vehicle and automatically adjusts the direction of the room mirror to correct blind spots according to the change of the driving direction of the vehicle, thereby causing a safety accident. It provides an effect that can prevent.
