Description

자동차용 리저탱크구조{Reservoir structure for a automobile}Reservoir structure for a automobile}

본 발명은 자동차용 리저탱크구조에 관한 것으로서, 더욱 더 상세하게는 리저버탱크의 주입구에 게이지와 리저버캡을 순차적으로 결합시켜 주는 것에 의해 상기 리저버탱크에 보관중인 냉각수 및 가열이 이루어진 냉각수 증기가 새어나가지 않도록 함과 동시에 상기 리저버탱크를 제작시 부품수 및 작업공정을 저감시켜 제작단가가 절감되도록 하는 자동차용 리저탱크구조에 관한 것이다.The present invention relates to a reservoir tank structure for automobiles, and more particularly, by combining the gauge and reservoir caps sequentially with the inlet of the reservoir tank, the coolant stored in the reservoir tank and the cooling water vapor made of heating leak out. The present invention relates to a reservoir tank structure for an automobile, which reduces the number of parts and a work process when manufacturing the reservoir tank and reduces the manufacturing cost.

일반적으로 리저버탱크는 엔진에서 가열된 냉각수가 라디에이터로 유입될 때 가열된 온도에 의하여 체적 팽창되는 냉각수가 라디에이터 캡에 내장된 압력조절밸브를 개방시키면서 리저버탱크로 유입, 저장되었다가 냉각수의 온도가 낮아지면 냉각수를 다시 라디에이터로 되돌려 보내도록 구성되어 있다.In general, the reservoir tank is introduced into and stored in the reservoir tank by opening the pressure control valve embedded in the radiator cap when the cooling water heated by the engine flows into the radiator. It is configured to return ground coolant back to the radiator.

이와 같이 냉각수 순환계통을 순환하는 냉각수는 자체의 증발 작용과 리저버탱크에서 발생되는 증발작용에 의하여 점차로 줄어들게 되므로 자동차를 운행하는 운전자 및 정비자는 수시로 냉각 수량을 점검하고, 냉각수가 부족할 경우 냉각수를 보충해 주어야 한다.As the coolant circulating in the coolant circulation system gradually decreases due to its own evaporation action and evaporation action generated in the reservoir tank, the driver and mechanic who operate the vehicle frequently check the amount of cooling and replenish the coolant when the coolant is insufficient. Should give.

따라서, 상기 리저버탱크에는 도 1에 도시하고 있는 바와 같이 냉각수를 저장하고 있는 리저버탱크몸체(110)에 형성된 냉각수 주입구(120)에 리저버캡(140)을 분리 가능하게 설치하여, 상기 리저버탱크몸체(110)의 내부에 냉각수를 보충시에는 리저버캡(140)을 냉각수 주입구(120)가 개방되도록 분리시키고, 상기 리저버캡(140)이 분리되어 개방이 이루어진 냉각수 주입구(120)를 통해 냉각수를 리저버탱크몸체(110)에 보충한 후에는 다시 냉각수 주입구(120)가 폐쇄되도록 리저버캡(140)을 냉각수 주입구(120)에 결합시켜, 상기 리저버탱크몸체(110)에 보관중인 냉각수가 외부로 인출되지 않도록 하고 있다.Accordingly, the reservoir tank 140 is detachably installed in the coolant inlet 120 formed in the reservoir tank body 110 storing the coolant, as shown in FIG. 1, so that the reservoir tank body ( When replenishing the coolant inside the reservoir 110, the reservoir cap 140 is separated so that the cooling water inlet 120 is opened, and the reservoir cap 140 is separated by the cooling water inlet 120 through which the cooling tank is opened. After replenishing the body 110, the reservoir cap 140 is coupled to the cooling water inlet 120 so that the cooling water inlet 120 is closed again, so that the cooling water stored in the reservoir tank body 110 is not drawn out. Doing.

한편, 상기 리저버캡(140)에는 도 2에 도시하고 있는 바와 같이 리저버탱크몸체(110)에 보관중인 냉각수의 양을 측정하기 위한 게이지(130)를 고정되게 결합시킴과 동시에, 상기 리저버탱크몸체(110)에 보관중인 냉각수 및 가열이 이루어진 냉각수 증기가 리저버캡(140)과 주입구(120)의 사이로 새어나오지 않도록 하는 고무재질의 패킹(150)을 설치하여, 리저버탱크몸체(110)에 보관중인 냉각수량을 파악하기 위해서 리저버캡(140)을 냉각수 주입구(120)로 부터 분리하여 위로 올리게 되면 리저버캡(140)의 저면에 결합되어 있는 게이지(130)가 밖으로 나오게 되는데, 이때 게이지(130)에 형성된 눈금에 표시되는 냉각수 자국을 보고 현재의 냉각수량을 파악하게 됨은 물론, 상기 리저버캡(140)을 주입구(120)가 폐쇄되도록 결합시키는 경우에는, 상기 주입구(120)의 상부면에 리저버캡(140)의 저면에 설치된 고무재질의 패킹(150)이 압착되는 것에 의해 기밀이 유지되어, 상기 리저버캡(140)과 주 입구(120) 사이를 통해 리저버탱크몸체(110)에 보관중인 냉각수 및 가열이 이루어진 냉각수 증기가 새어나가 리저버탱크(100)가 설치되어 있는 엔진룸 주변이 오염되는 것이 방지되도록 하고 있다.Meanwhile, as shown in FIG. 2, the reservoir cap 140 is fixedly coupled to the gauge 130 for measuring the amount of cooling water stored in the reservoir tank body 110, and the reservoir tank body ( Cooling water being stored in the cooling water and the cooling water vapor is heated in the reservoir cap 140 and the injection port 120 is installed in the packing 150 of the rubber material, so that the cooling in the reservoir tank body 110 When the reservoir cap 140 is lifted up from the cooling water inlet 120 to grasp the quantity, the gauge 130 coupled to the bottom surface of the reservoir cap 140 comes out, wherein the gauge 130 is formed in the gauge 130. By looking at the coolant marks displayed on the scale to determine the current amount of coolant, of course, when the reservoir cap 140 is coupled to the inlet 120 to be closed, the upper surface of the inlet 120 The airtightness is maintained by compressing the packing of the rubber material 150 installed on the bottom of the reservoir cap 140, and being stored in the reservoir tank body 110 through the reservoir cap 140 and the main inlet 120. The cooling water and the cooling water vapor, which has been heated, are leaked to prevent contamination of the surroundings of the engine room in which the reservoir tank 100 is installed.

그러나 종래에는 상기 리저버탱크몸체(110)의 주입구(120)에 결합 및 분리되는 리저버캡(140)의 저면에 게이지(130)가 결합되도록 돌출핀(142)을 열가압시켜 녹여야 함은 물론, 상기 게이지(130)가 결합되어 있는 리저버캡(140)의 저면에는 고무재질의 패킹(150)을 너트스프링(160)을 이용해 고정되게 설치하여 리저버탱크몸체(110)의 주입구(11)에 리저버캡(140)을 결합 시 기밀이 유지되도록 하여야 함으로써, 리저버탱크(100)를 제작시 부품 수 및 작업공정이 증가하여 제작단가가 상승하게 되는 문제점이 있었다.However, in the related art, the protruding pins 142 are thermally pressurized to be melted so that the gauge 130 is coupled to the bottom of the reservoir cap 140 which is coupled to and separated from the injection port 120 of the reservoir tank body 110. On the bottom surface of the reservoir cap 140 to which the gauge 130 is coupled, a rubber packing 150 is fixedly installed using the nut spring 160 so that the reservoir cap may be inserted into the inlet 11 of the reservoir tank body 110. Since the airtightness is to be maintained at the time of combining 140, the manufacturing cost increases due to an increase in the number of parts and a work process when the reservoir tank 100 is manufactured.

한편, 종래에는 상기 게이지(130)를 리저버캡(140)의 저면에 형성되어 있는 돌출핀(142)을 열가압시켜 녹이면서 결합 시, 결합 불량이 종종 발생하게 되는 문제점이 있었다.On the other hand, conventionally, when the gauge 130 is coupled by thermally pressing and melting the protruding pins 142 formed on the bottom surface of the reservoir cap 140, there is a problem that a coupling failure is often caused.

본 발명의 목적은 리저버탱크몸체의 주입구에 게이지와 리저버캡을 순차적으로 결합시켜 주는 것에 의해 상기 리저버탱크몸체 내에 보관중인 냉각수 및 가열이 이루어진 냉각수 증기가 새어나가지 않도록 함과 동시에 리저버탱크를 제작 시 부품수 및 작업공정을 저감시켜 제작단가가 절감되도록 하는 자동차용 리저탱크구조 를 제공하는데 있다.It is an object of the present invention to prevent the leakage of the cooling water and the cooling water vapor that is stored in the reservoir tank body by sequentially coupling the gauge and the reservoir cap to the inlet of the reservoir tank body, and at the same time when manufacturing the reservoir tank The present invention provides a tank structure for automobiles in which manufacturing cost is reduced by reducing water and work processes.

상기 목적 달성을 위한 본 발명은, 냉각수 주입구가 돌출되게 형성되어 있는 리저버탱크몸체와, 상기 리저버탱크몸체에 보관중인 냉각수의 양을 측정하는 게이지와, 상기 게이지에 의해 측정이 이루어지고 있는 냉각수가 주입구를 통해 유출되지 않도록 하는 리저버캡으로 구성되는 리저버탱크에 있어서, 상기 리저버캡과 게이지가 상호 분리되어 구성되고, 상기 게이지의 중앙부위에는 안착부가 돌출되어 형성되며, 상기 안착부가 안착되는 걸림턱이 냉각수 주입구에 내삽지게 형성되는 것에 의해 달성된다. The present invention for achieving the above object is a reservoir tank body in which a coolant inlet is formed to protrude, a gauge for measuring the amount of coolant stored in the reservoir tank body, and the coolant inlet measured by the gauge In the reservoir tank consisting of a reservoir cap that does not flow through the reservoir, the reservoir cap and the gauge is configured to be separated from each other, the center portion of the gauge is formed with a protruding seating portion, the locking jaw seated on the seating portion is a cooling water inlet By being interpolated in.

한편, 상기 안착부는 주입구의 내측벽면에 외측면이 밀착되는 접촉면과, 걸림턱에 안착이 이루어지는 안착돌기를 갖도록 절곡 형성됨을 밝혀 둔다.On the other hand, the seating portion is turned out to be bent to have a contact surface that is in close contact with the outer surface to the inner wall surface of the injection port, and a seating projection to be seated on the locking jaw.

이와 같은 본 발명에 의하면 게이지의 안착부가 냉각수 주입구의 걸림턱에 걸리어 안착이 이루어지는 것에 의해 리저버탱크몸체에 보관중인 냉각수 및 가열이 이루어진 냉각수 증기가 새어나가지 않게 기밀이 유지되어 지게 됨으로써, 상기 냉각수 주입구에 결합되는 리저버캡에 기밀이 유지되도록 하는 별물의 패킹을 설치하지 않아도 됨은 물론, 상기 리저버캡에 게이지를 고정되게 결합시키지 않아도 되어 리저버탱크를 제작 시 부품수 및 작업공정이 저감되어 제작단가가 절감되어지게 됨 은 물론, 불량률이 저하되어지게 되는 등의 효과가 있다. According to the present invention, the seating portion of the gauge is caught by the catching jaw of the cooling water inlet, and thus the airtightness is maintained so that the cooling water stored in the reservoir tank body and the cooling water vapor which is heated are not leaked. There is no need to install a separate packing to maintain the air tightness in the reservoir cap coupled to the reservoir, and the gauge does not need to be fixedly fixed to the reservoir cap, thereby reducing the number of parts and the work process when manufacturing the reservoir tank, thereby reducing the manufacturing cost. Of course, there is an effect such that the failure rate is lowered.
