Description
본 발명은 자동차용 와셔노즐에 관한 것으로서, 더욱더 상세하게는 자율주행차에 설치된 카메라와 각종 센서 및 윈드실드 글래스와 리어글래스로 스프레이노즐을 통해 워셔액이 분사되도록 함으로써, 자동차를 운행시 적은양의 워셔액으로도 효과적인 세척이 이루어질 수 있도록 하는 자동차용 와셔노즐에 관한 것이다.The present invention relates to a washer nozzle for automobiles, and more specifically, to spray washer fluid through a spray nozzle to the camera, various sensors, windshield glass, and rear glass installed in an autonomous vehicle, thereby allowing a small amount of washer fluid to be consumed when driving the car. This relates to a washer nozzle for automobiles that allows effective cleaning.
일반적으로 차실내의 전방에는 주행 중에 불어오는 바람을 막거나, 전방의 시야를 확보하기 위한 윈드실드(windshield)가 설치되어 있다.Generally, a windshield is installed at the front of the vehicle interior to block wind blowing during driving or to secure forward visibility.
이러한 윈드실드의 표면은 먼지와 같은 이물질에 자주 오염되기 때문에 전방시야를 충분히 확보하여 안전운행을 도모하기 위해서는 유리면에 묻은 먼지와 같은 이물질을 제거하여야 한다.Since the surface of the windshield is frequently contaminated with foreign substances such as dust, foreign substances such as dust on the glass surface must be removed in order to ensure sufficient forward visibility and ensure safe driving.
이렇게 차량의 윈드실드에 묻은 이물질 등의 제거를 위해 차량에는 와이퍼 시스템과 함께 와셔액 분사를 위한 와셔노즐이 갖추어져 있다.To remove foreign substances from the vehicle's windshield, the vehicle is equipped with a wiper system and a washer nozzle for spraying washer fluid.
따라서, 운전자가 시야를 맑게 하기 위해 운전석에 설치된 와셔 스위치를 조작하게 되면, 와셔 스위치와 연계된 와셔 모터가 작동하고, 와셔 모터의 작동에 의해 와셔액 저장탱크 내부에 저장되어 있던 와셔액은 와셔노즐을 통해 윈드실드에 분사되며, 이렇게 분사된 와셔액과 와이퍼 작동을 통해 운전에 방해되는 이물질을 제거하여 운전자는 시야가 확보된 상태에서 안전한 주행을 할 수 있다.Therefore, when the driver operates the washer switch installed in the driver's seat to clear the field of view, the washer motor linked to the washer switch operates, and the operation of the washer motor causes the washer fluid stored inside the washer fluid storage tank to flow through the washer nozzle. It is sprayed on the windshield, and through the sprayed washer fluid and wiper operation, foreign substances that interfere with driving are removed, allowing the driver to drive safely with clear visibility.
보통 차량용으로 적합한 와셔 노즐은 단시간에 적은 양의 세정액으로 넓은 영역을 세정하는 성능을 필요로 한다.Washer nozzles suitable for general vehicles require the ability to clean a large area with a small amount of cleaning fluid in a short period of time.
이때, 상기 와셔액이 역류되는 현상을 방지하기 위해 특허문헌1은 입구측 본체와 출구측 본체를 결합하고, 그 내부에 탄성스프링의 지지를 받는 역류방지체를 설치한 것으로서, 상기 입구측본체의 내측면 안쪽에 테이퍼면을 구성하고, 상기 역류방지체는 입구측본체의 내부에 삽입되는 안내부와 상기 안내부와 원통의 몸체의 사이에는 상기 입구측 본체의 테이퍼면과 일치하는 테이퍼부를 가지도록 구성되어 있다. At this time, in order to prevent the washer fluid from flowing back, Patent Document 1 combines the inlet side body and the outlet side body and installs a backflow prevention member supported by an elastic spring therein, and the inside of the inlet side body is installed. A tapered surface is formed on the inside of the side, and the backflow prevention body is configured to have a guide part inserted into the inside of the inlet side main body and a tapered part between the guide part and the cylindrical body that matches the tapered surface of the inlet side main body. It is done.
그러나, 종래의 특허문헌1은 와셔액의 순류시 공급되는 와셔액의 압력이 역류방지체를 지지하고 있던 탄성스프링의 탄성력보다 커지게 되면, 역류방지체가 출구측 본체의 유로를 일부분 또는 전체를 막게되어 노즐에서 와셔액이 일정한 양으로 분사되지 못하는 현상이 발생되지 않는 문제점이 있었다.However, conventional Patent Document 1 states that when the pressure of the washer fluid supplied during the forward flow of the washer fluid becomes greater than the elastic force of the elastic spring supporting the backflow prevention member, the backflow prevention member blocks part or all of the flow path of the outlet side main body, causing the nozzle to block. There was a problem in which washer fluid was not sprayed in a certain amount.
한편, 상기 역류방지체의 외주면으로 다수개의 가이드돌기가 일체로 형성되어 있기 때문에, 와셔액의 순류시 공급되는 와셔액과 마찰에 의해 역류방지체의 가이드돌기에 회전현상이 발생되어 다수개의 가이드돌기 사이의 유동공간으로 유동하던 와셔액도 같이 회전되는 것에 의해 상기 노즐에 와셔액이 공급되는 시간이 지체되어 상기와 마찬가지로, 노즐에서 와셔액이 일정한 양으로 분사되지 못하는 현상이 발생되는 문제점이 있었다.Meanwhile, since a plurality of guide protrusions are integrally formed on the outer peripheral surface of the backflow prevention body, a rotation phenomenon occurs in the guide protrusion of the backflow prevention body due to friction with the washer fluid supplied when the washer fluid flows, causing a gap between the plurality of guide projections. As the washer fluid flowing in the flow space was also rotated, the time for the washer fluid to be supplied to the nozzle was delayed, causing a problem in which washer fluid was not sprayed in a constant amount from the nozzle, as described above.
또한, 상기 자동차용 와셔노즐은 입구측 본체와 출구측 본체를 결합하고, 그 내부에 탄성스프링의 지지를 받는 역류방지체를 설치하여야 함으로써, 상기 와셔노즐을 제작시 부품수가 증가하고 작업공정이 증가하여 많은 조립시간을 필요로 하게되는 되는 문제점이 있었다. In addition, the washer nozzle for automobiles combines the inlet side body and the outlet side body, and installs a backflow prevention member supported by an elastic spring therein, so the number of parts increases and the work process increases when manufacturing the washer nozzle. Therefore, there was a problem in that it required a lot of assembly time.
본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서, 자율주행차에 설치된 카메라와 각종 센서 및 윈드실드 글래스와 리어글래스에 와셔액이 역류가 방지되면서 일정한 양으로 분사되도록 하는 자동차용 와셔노즐을 제공하는 데 있다.The purpose of the present invention is to solve the above-described conventional problems, and to prevent washer fluid from flowing back into the camera, various sensors, windshield glass, and rear glass installed in an autonomous vehicle, and to spray washer fluid in a constant amount for automobiles. The purpose is to provide washer nozzles.
본 발명의 다른 목적은 와셔액이 역류가 방지되면서 일정한 양으로 분사되도록 와셔노즐을 조립시에도 부품수가 저감되어 조립시간이 단축되도록 함과 동시에 생산단가가 절감될 수 있도록 하는 자동차용 와셔노즐을 제공하는 데 있다.Another object of the present invention is to provide a washer nozzle for automobiles that reduces the number of parts and shortens the assembly time when assembling the washer nozzle so that the washer fluid is sprayed in a constant amount while preventing backflow, and at the same time reduces the production cost. There is.
상기와 같은 목적을 달성하기 위한 본 발명은 주유입로(130)로 유입이 이루어지는 워셔액을 분사공(110)을 통해 외부로 분사시키는 노즐(100)과, 상기 노즐(100)의 주유입로(130)와 연통되는 유로(210)를 가지며 노즐(100)에 고정되게 결합되는 니플(200)과, 상기 니플(200)에 형성된 유로(210)를 개폐시키면서 노즐(100)의 주유입로(130)로 워셔액을 공급 및 차단시키는 체크밸브(300)로 구성되는 것에 의해 달성된다. The present invention for achieving the above object includes a nozzle 100 that sprays washer fluid flowing into the main inlet 130 to the outside through the injection hole 110, and a main inflow path of the nozzle 100 ( A nipple 200 that has a flow path 210 in communication with the nozzle 100 and is fixedly coupled to the nozzle 100, and a main inflow path 130 of the nozzle 100 while opening and closing the flow path 210 formed in the nipple 200. ) is achieved by being composed of a check valve 300 that supplies and blocks washer fluid.
한편, 상기 노즐(100)의 주유입로 방향에 결합되는 니플(200) 일측단부에는 유로(210)와 연통되는 연결공(221)이 관통되어 형성된 돌기부(220)가 외측으로 돌출되어 형성됨을 밝혀 둔다.Meanwhile, it was revealed that at one end of the nipple 200 coupled to the main inlet direction of the nozzle 100, a protrusion 220 formed by penetrating a connection hole 221 in communication with the flow path 210 is formed to protrude outward. put it
또한, 상기 체크밸브(300)는 유로(210)로 워셔액이 유입되면 팽창되면서 돌기부(220)의 연결공(221)을 개방시키면서 주유입로(130)로 워셔액을 공급하고, 상기 유로로 고와셔액의 유입이 차단되면 돌기부(220)의 연결공(221)이 차단되도록 자체탄성력에 의해 돌기부(220)의 외측면에 밀착되도록 형성됨을 밝혀 둔다. In addition, the check valve 300 expands when washer fluid flows into the flow path 210, opens the connection hole 221 of the protrusion 220, and supplies washer fluid to the main inflow path 130. It should be noted that it is formed to adhere closely to the outer surface of the protrusion 220 by its own elastic force so that when the inflow of the protrusion 220 is blocked, the connection hole 221 of the protrusion 220 is blocked.
한편, 상기 체크밸브(300)는 자체탄성력을 갖고 있는 러버재로 구성되어, 노즐(100)에 워셔액의 누수현상이 발생하지 않도록 함이 더욱바람직 하다.Meanwhile, it is more desirable that the check valve 300 is made of a rubber material having its own elastic force to prevent washer fluid from leaking into the nozzle 100.
또한, 상기 노즐(100)에는 분사공(110)을 통해 분사되는 워셔액을 확산시키는 확산부(120)가 절곡 형성됨을 밝혀 둔다. In addition, it should be noted that the nozzle 100 is formed with a bent diffusion portion 120 that diffuses the washer fluid sprayed through the injection hole 110.
한편, 상기 분사공(110)은 주유입로(130)의 내경보다 작은 내경을 갖도록 작게 형성됨이 더욱 바람직 함을 밝혀둔다.Meanwhile, it should be noted that it is more preferable that the injection hole 110 is formed small to have an inner diameter smaller than the inner diameter of the main inflow passage 130.
본 발명에 따르면 차량에 설치된 카메라와 각종 센서 및 윈드실드 글래스와 리어글래스를 세척시 니플의 유로로 유입되는 와셔액의 유압에 의해 체크밸브가 팽창되면서 돌기부의 연결공이 개방되어 노즐의 주유입로로 유입된 후 분사공을 통해 와셔액이 세척하고자 하는 세척물에로 분사되면서 세척을 수행하게 됨으로써, 적은양의 세척수로도 효율적으로 세척하고자 하는 세척물을 세척할 수 있게되는 효과가 있다. According to the present invention, when cleaning the camera, various sensors, windshield glass, and rear glass installed in the vehicle, the check valve is expanded by the hydraulic pressure of the washer fluid flowing into the nipple passage, and the connection hole of the protrusion is opened, and the fluid flows into the main inlet passage of the nozzle. After washing, the washer fluid is sprayed onto the object to be cleaned through the spray hole, thereby performing cleaning, which has the effect of efficiently cleaning the object to be cleaned even with a small amount of washing water.
한편, 본 발명에 따르면 세척이 완료된 후에는 체크밸브에 의해 노즐의 주유입로로 와셔액이 유입되는 것이 차단되어 낙수등이 발생되어 세척물이 오염되지 않게 되는 등의 효과가 있는 매우 유용한 발명이다. On the other hand, according to the present invention, after cleaning is completed, the washer fluid is blocked from flowing into the main inlet passage of the nozzle by the check valve, thereby preventing the washing material from being contaminated due to dripping water, etc., which is a very useful invention.
