Description

Automotive Washer Assembly {Automotive washer assembly}

본 발명은 자동차의 윈도글래스를 세정하기 위한 와셔액을 분사하는 와셔 어셈블리에 관한 것이다.The present invention relates to a washer assembly for spraying a washer liquid for cleaning the window glass of a motor vehicle.

자동차의 앞유리에 먼지가 끼면 운전자의 시야가 흐려져 안전 운행에 방해가 된다. 따라서, 일반적인 자동차에는 앞유리에 와셔액을 분사하는 와셔 어셈블리와 이러한 와셔 어셈블리로부터 분사된 와셔액을 이용하여 유리면을 닦는 와이퍼가 설치되어 있다.Dirt on the windshield of a car can blur the driver's vision and interfere with safe driving. Therefore, a typical vehicle is provided with a washer assembly for spraying the washer liquid on the windshield and a wiper for wiping the glass surface using the washer liquid injected from the washer assembly.

이중에서 와셔액을 분사하는 와셔 어셈블리는, 도 1에 도시된 바와 같이, 와셔액이 저장되는 와셔 탱크(1)와, 와셔액을 유리면을 향해 분사하는 노즐(미도시)과, 탱크(1)에 저장된 와셔액을 튜브(3)를 통해 노즐(미도시)로 펌핑하는 와셔 펌프(2)를 포함하고 있다.As shown in FIG. 1, the washer assembly for spraying the washer liquid includes a washer tank 1 in which the washer liquid is stored, a nozzle (not shown) for spraying the washer liquid toward the glass surface, and a washer liquid stored in the tank 1. It includes a washer pump (2) for pumping through the tube (3) to a nozzle (not shown).

와셔 탱크(1)의 소정 위치에는 블로워 공법에 의해 소정의 함몰 공간이 형성되며, 이러한 함몰 공간(1a)에 와셔 펌프(2)가 삽입되어져 장착된다.A predetermined recessed space is formed at a predetermined position of the washer tank 1 by a blower method, and the washer pump 2 is inserted into and mounted in the recessed space 1a.

일반적으로, 이러한 와셔 어셈블리의 와셔 펌프(2)는 고속으로 작동되면, 그 진동 및 작동음의 소음이 대략 57db이다.In general, when the washer pump 2 of this washer assembly is operated at high speed, the vibration and noise of the operation sound are approximately 57 db.

하지만, 이러한 종래의 와셔 어셈블리는 도 2에 도시된 바와 같이, 와셔 펌프(2)가 와셔 탱크(1)의 함몰 공간(1a)에 장착됨으로써, 와셔 펌프(2)의 작동음 및 진동이 와셔 탱크(1)의 밀폐된 공간 내로 전달되어 공명 현상(도 2의 화살표 참조)을 일으켜, 와셔 펌프(2)의 작동음 및 진동이 증폭되어 정숙한 운전에 매우 방해가 되는 단점이 있었다.However, in the conventional washer assembly, as shown in FIG. 2, the washer pump 2 is mounted in the recessed space 1a of the washer tank 1, so that the operation sound and vibration of the washer pump 2 are reduced. It was transmitted to the closed space of (1) to cause a resonance phenomenon (see the arrow in Fig. 2), there was a disadvantage that the operation sound and vibration of the washer pump (2) is amplified and very disturbed in the quiet operation.

따라서, 본 발명은 상기와 같은 점을 감안하여 안출한 것으로, 와셔 펌프로부터 발생하는 각종 진동 및 작동음이 와셔 탱크로 전달되는 것을 방지함으로써, 운전자가 정숙한 운전을 할 수 있도록 하는 자동차용 와셔 어셈블리를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and the vehicle washer assembly which enables the driver to operate quietly by preventing various vibrations and operation sounds generated from the washer pump from being transferred to the washer tank. The purpose is to provide.

The washer liquid is stored in the washer tank 10.

방진 부재(30)는 고무 재질 등과 같은 진동을 흡수할 수 있는 재질로 이루어져, 상술한 와셔 탱크(10)의 펌프 고정용 플랜지(10a)에 결합된다. 도 4에 도시된 바와 같이, 방진 부재(30)는 반원형으로 성형될 수도 있으며, 방진 부재(30)의 양단부에는 걸림턱(30a)이 형성되어 상술한 와셔 탱크(10)의 펌프 고정용 플랜지(10a)의 걸림홈(10c)에 끼워져 결합된다.The anti-vibration member 30 is made of a material capable of absorbing vibration, such as a rubber material, and is coupled to the pump fixing flange 10a of the washer tank 10 described above. As shown in FIG. 4, the anti-vibration member 30 may be formed in a semi-circular shape, and the locking jaw 30a is formed at both ends of the anti-vibration member 30 so that the pump fixing flange of the washer tank 10 may be formed. It is fitted into the engaging groove (10c) of 10a.

와셔 펌프(20)는 원통 형상으로 형성되고, 그 일측에 와셔액을 토출하는 토출구(20a)가 형성되고, 그 하부에는 와셔 탱크(10)의 내부에 저장된 와셔액을 흡입하는 흡입관(20b)이 형성된다. 이러한 와셔 펌프(20)는, 그 외주 일측면이 방진 부재(30)가 결합된 와셔 탱크(10)의 펌프 고정용 플랜지(10a)에 수용됨과 동시에 그 하부에 형성된 흡입관(20b)이 와셔 탱크(10)의 배출구(10b)에 삽입됨으로써, 와셔 탱크(10) 상에 장착된다.The washer pump 20 is formed in a cylindrical shape, and a discharge port 20a for discharging washer liquid is formed at one side thereof, and a suction pipe 20b for suctioning the washer liquid stored inside the washer tank 10 is formed at a lower portion thereof. . The washer pump 20 has one outer circumferential side of the washer tank 20b accommodated in the pump fixing flange 10a of the washer tank 10 to which the anti-vibration member 30 is coupled, and the suction pipe 20b formed at the lower portion thereof has a washer tank ( It is mounted on the washer tank 10 by being inserted in the outlet 10b of 10).

노즐(미도시)은 윈드실드 글래스(미도시)에 근접하여 장착되고, 상술한 와셔 펌프(20)의 토출관(20a)으로부터 연결된 튜브(40)를 통해 토출되는 와셔액을 윈드실드 글래스(미도시) 측으로 분무한다.The nozzle (not shown) is mounted close to the windshield glass (not shown), and the washer liquid discharged through the tube 40 connected from the discharge tube 20a of the washer pump 20 described above is windshield glass (not shown). Spray to the side.

와셔 펌프(20)는 와셔 탱크(10) 내에 저장된 와셔액을 노즐(미도시) 측으로 펌핑하고, 노즐(미도시)은 윈드실드 글래스 측으로 와셔액을 분무한다. 이때, 와셔 펌프(20)에서 각종 진동 및 작동음이 발생되며, 이때, 와셔 펌프(20)로부터 발생한 진동 및 작동음은 방진 부재(30)에 흡수되어 와셔 탱크(10)로 전달되는 것이 방지되는 특징이 있다.The washer pump 20 pumps the washer liquid stored in the washer tank 10 to the nozzle (not shown) side, and the nozzle (not shown) sprays the washer liquid to the windshield glass side. In this case, various vibrations and operation sounds are generated in the washer pump 20, and at this time, the vibrations and operation sounds generated from the washer pump 20 are prevented from being absorbed by the dustproof member 30 and transmitted to the washer tank 10. There is a characteristic.

상기와 같은 본 발명은, 와셔 펌프로부터 발생하는 각종 진동 및 작동음이 와셔 탱크로 전달되는 것을 방지함으로써, 운전자가 정숙한 운전을 할 수 있도록 하는 매우 뛰어난 효과가 있다.The present invention as described above has a very excellent effect of allowing the driver to operate quietly by preventing various vibrations and operation sounds generated from the washer pump from being transmitted to the washer tank.
