차량용 와이퍼모터의 소손방지장치{Apparatus for preventing damage of wiper motor in a vehicle}Apparatus for preventing damage of wiper motor in a vehicle}

본 발명은 차량용 와이퍼모터의 소손방지장치에 관한 것으로서, 보다 상세하게는 차량용 와이퍼를 구동하는 와이퍼 모터의 과열시에 전원공급을 차단하여 차후 와이퍼 모터의 정상적인 복귀구동이 가능하도록 하는 차량용 와이퍼모터의 소손방지장치에 관한 것이다.The present invention relates to an apparatus for preventing burnout of a vehicle wiper motor, and more particularly, a burnout of a vehicle wiper motor which cuts the power supply when the wiper motor driving the vehicle wiper is overheated to enable a normal return drive of the wiper motor later. It relates to a prevention device.

일반적으로, 우천시나 동절기에 눈이 내리는 상태에서 차량의 전방 시야를 확보하기 위해 와이퍼장치가 적용되는 바, 이러한 와이퍼장치는 와이퍼모터의 구동을 통해서 와이퍼가 차량의 전면 유리를 왕복운동하도록 되어 있다.In general, a wiper device is applied to secure a forward view of the vehicle in rainy weather or in winter, such a wiper device is configured to allow the wiper to reciprocate the windshield of the vehicle by driving the wiper motor.

도 1은 종래의 일반적인 차량용 와이퍼 구동회로에 대한 구성을 나타낸 도면으로서, 이러한 차량용 와이퍼 구동회로는 와이퍼 모터부(4) 및 회로 브레이커(2)를 갖춘 와이퍼 모터와, 와이퍼 릴레이(6), 와이퍼 스위치(14), 다기능 스위치(12)로 구성된다.1 is a view showing a configuration of a conventional vehicle wiper drive circuit in the prior art, such a vehicle wiper drive circuit is a wiper motor having a wiper motor unit 4 and a circuit breaker (2), a wiper relay (6), a wiper switch 14, the multifunction switch 12.

상기 회로 브레이커(2)는 일단이 퓨즈(FUSE)를 매개하여 배터리전원(DC)과 연결되고 타단이 와이퍼 모터부(4)와 연결되고서, 상기 와이퍼 모터부(4)의 회전구동중 과열이 발생되면 작동되어 배터리전원(DC)의 공급을 차단시키게 된다.One end of the circuit breaker 2 is connected to the battery power source DC through a fuse FUSE and the other end is connected to the wiper motor unit 4, so that overheating during rotation of the wiper motor unit 4 is performed. It is activated when it is generated to cut off the supply of battery power (DC).

상기 와이퍼 모터부(4)는 그 일단이 상기 회로 브레이커(2)를 매개로 배터리전원(DC)과 연결되고 타단이 상기 와이퍼 릴레이(6)의 릴레이 스위치(8)와 연결되고서, 상기 와이퍼 릴레이(6)의 스위칭동작에 따라 도통되면서 배터리전원(DC)을 인가받아 회전구동된다.The wiper motor unit 4 has one end connected to the battery power supply DC via the circuit breaker 2 and the other end connected to the relay switch 8 of the wiper relay 6, and thus the wiper relay In accordance with the switching operation of (6) is conducted and is rotated by receiving the battery power (DC).

상기 와이퍼 릴레이(6)는 그 릴레이 코일(10)의 일단이 퓨즈(FUSE)를 매개하여 배터리전원(DC)과 연결되고 타단이 다기능 스위치(12)와 연결되고서, 상기 와이퍼 스위치(14)의 스위칭동작과 다기능 스위치(12)의 스위칭에 따라 릴레이 코일(10)이 여자되면서 그 릴레이 스위치(8)가 스위칭동작되어 와이퍼 모터부(4)가 회전구동되도록 한다.The wiper relay 6 has one end of the relay coil 10 connected to the battery power supply DC via a fuse and the other end connected to the multifunction switch 12, so that the wiper switch 14 In response to the switching operation and the switching of the multifunction switch 12, the relay coil 10 is excited and the relay switch 8 is switched to cause the wiper motor unit 4 to rotate.

그러나, 이러한 종래의 와이퍼 구동회로는 와이퍼 릴레이(6)가 스위칭동작되어 와이퍼 모터부(4)가 회전구동되는 도중에 그 와이퍼 모터부(4)가 과열되면, 회로 브레이커(2)가 작동되어 와이퍼 모터부(4)에 인가되는 전원은 차단되지만, 와이퍼 릴레이(6)는 스위칭온 상태가 유지되어 있기 때문에, 회로 브레이커(2)가 정상상태로 복귀되면 순간적인 서지전류(Surge Current)가 와이퍼 모터부(4)에 인가됨에 따라 소손이 발생된다는 문제점이 있다.However, in such a conventional wiper drive circuit, if the wiper motor part 4 is overheated while the wiper relay 6 is switched and the wiper motor part 4 is rotationally driven, the circuit breaker 2 is activated to operate the wiper motor. The power applied to the unit 4 is cut off, but since the wiper relay 6 is kept in a switched-on state, when the circuit breaker 2 returns to a normal state, a momentary surge current is generated in the wiper motor unit. There is a problem that burnout occurs as applied to (4).

따라서, 본 발명은 상기한 종래의 사정을 감안하여 이루어진 것으로서, 그 목적은 와이퍼 모터의 회로 브레이커가 작동되어 전원이 차단되면 와이퍼 릴레이의 스위칭이 해제될 수 있도록 함에 의해, 와이퍼의 동작이 복귀되더라도 회로의 소손이 방지될 수 있도록 하는 차량용 와이퍼모터의 소손방지장치를 제공하는 것이다.Accordingly, the present invention has been made in view of the above-described conventional situation, and an object thereof is that the circuit breaker of the wiper motor is operated so that the switching of the wiper relay can be released when the power is cut off, even if the wiper operation is restored. It is to provide a burnout preventing device for a vehicle wiper motor to prevent burnout of the vehicle.
