본 발명은 차량 연료탱크의 리저버 컵 및 배플구조에 관한 것으로서, 보다 상세하게는 연료탱크 내부에 수용되어 있는 리저버 컵에 가이드홈을 구비하고, 상기 가이드홈에 끼워져 체결될 수 있도록 배플에 가이드를 구비함으로써 용접작업이 필요 없는 소형차 연료탱크에 적합한 배플 결합형 리저버 컵에 관한 것이다.The present invention relates to a reservoir cup and a baffle structure of a vehicle fuel tank, and more particularly, a guide groove is provided in a reservoir cup accommodated inside the fuel tank, and a guide is provided in the baffle so as to be fitted into the guide groove. The present invention relates to a baffle coupled reservoir cup suitable for a fuel tank of a small vehicle without welding.

일반적으로 자동차의 연료탱크는 엔진구동을 위해 소비되는 연료를 저장하는 용기로서, 종래에는 도 1에 도시된 바와 같이, 연료탱크(1)의 내부 바닥면에 배플(3)을 수직으로 세워 설치하고, 상기 배플(3)에는 연료가 통과하기 위한 구멍(4)을 형성하여 차량의 가감속시 연료의 유속을 줄여주어 연료의 유동에 의한 소음(유동음)을 감소시키거나, 차량이 일측으로 기울어진 경우에도 연료의 출렁임을 방지하여 연료의 출렁임에 의한 소음을 감소시킬 수 있도록 구성되어 있다.In general, a fuel tank of an automobile is a container for storing fuel consumed for driving an engine. As shown in FIG. 1, a baffle 3 is vertically installed on an inner bottom surface of a fuel tank 1. In the baffle (3) to form a hole (4) for the fuel to pass through to reduce the flow rate of the fuel during acceleration and deceleration of the vehicle to reduce the noise (flow noise) due to the flow of the fuel, or the vehicle tilted to one side It is configured to reduce the noise caused by the fuel rumble by preventing the rumble of the fuel even in the case of a loss.

한편, 상기한 배플(3)은 통상 금속재료로 제작되며, 도 1 및 도 2에서와 같이 용접부(2)가 연료탱크(1)의 내부에 점용접을 통해 고정체결되게 되는데, 소형차의 경우 대형차에 비해서 상대적으로 유동음이 적음에도 불구하고 동일하게 연료탱크의 상단에 용접을 함으로써 배플을 고정시키고 있다.On the other hand, the baffle (3) is usually made of a metal material, as shown in Figures 1 and 2, the welding portion 2 is fixed to the interior of the fuel tank (1) by spot welding, in the case of a small car Despite the relatively low flow noise, the baffle is fixed by welding the upper end of the fuel tank.

그러나, 이와 같이 배플을 연료탱크에 점용접하여 고정시키는 종래 기술에 따른 방식은 배플의 위치를 잘못 선정하여 유동음이 발생하는 경우 배플 튜닝이 어렵고, 튜닝을 위해 많은 시간과 투자비를 필요로 한다는 문제가 있다.However, the conventional method of spot welding the baffle to the fuel tank and fixing it is difficult to tune the baffle when the baffle is incorrectly selected and the flow noise is generated, which requires a lot of time and investment cost. There is.

그리고, 연료탱크 상단에 용접을 함으로써 정부압 내구 또는 부압 내구시 상기 연료탱크 상단에서 크랙이 발생하여 연료가 외부로 누유되는 문제점은 물론, 수차에 걸친 용접작업은 부품의 원가상승이라는 문제점도 초래하게 된다.And, by welding to the upper end of the fuel tank cracking occurs at the top of the fuel tank when the government pressure durability or negative pressure endurance, as well as the oil leakage to the outside, as well as the welding work over a number of times cause a problem that the cost of parts do.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 연료탱크 내부에 수용되어 있는 리저버 컵에 가이드홈을 구비하고, 상기 가이드홈에 끼워져 체결될 수 있도록 배플에 가이드를 구비함으로써 용접작업이 필요 없는 소형차 연료탱크에 적합한 배플 결합형 리저버 컵을 제공하는데 있다.The present invention has been made in order to solve the above problems, a welding groove is required by having a guide groove in the reservoir cup accommodated in the fuel tank, and having a guide in the baffle to be fitted into the guide groove. The present invention provides a baffle coupled reservoir cup suitable for a small vehicle fuel tank.

상기한 기술적 과제를 해결하기 위한 본 발명에 따른 배플 결합형 리저버 컵은, 연료탱크 내부에 수용되어 연료의 누출방지를 위한 리저버 컵에 있어서, 배플의 하단부에 구비되어 있는 가이드가 끼워져 고정체결될 수 있도록 리저버 컵의 측면에 가이드홈이 구비되어 있는 것을 특징으로 한다.The baffle coupled reservoir cup according to the present invention for solving the above technical problem, in the reservoir cup for receiving the fuel leakage inside the fuel tank, the guide provided in the lower end of the baffle can be fitted and fastened It is characterized in that the guide groove is provided on the side of the reservoir cup.

또한, 상기 배플은 배플 플레이트의 일측면에 상기 배플 플레이트와 전체적으로 직각을 이루도록 가이드가 연결되는 것을 특징으로 한다.In addition, the baffle is characterized in that the guide is connected to form a right angle with the baffle plate as a whole on one side of the baffle plate.

이하, 첨부된 도면에 따라 본 발명에 따른 배플 결합형 리저버 컵의 구성과 작용을 상세하게 설명하기로 한다.Hereinafter, the configuration and operation of the baffle coupled reservoir cup according to the present invention according to the accompanying drawings will be described in detail.

도 3은 본 발명에 따른 배플 결합형 리저버 컵과 배플이 체결된 상태를 나타낸 사시도이고, 도 4는 본 발명에 따른 배플 결합형 리저버 컵을 나타낸 사시도이며, 도 5는 본 발명에 따른 배플을 나타낸 사시도이고, 도 6은 본 발명에 따른 배플 결합형 리저버 컵에 배플이 체결되어 연료탱크에 장착된 상태를 나타낸 사시도이다.3 is a perspective view illustrating a state in which a baffle coupled reservoir cup and a baffle are fastened according to the present invention, FIG. 4 is a perspective view illustrating a baffle coupled reservoir cup according to the present invention, and FIG. 5 is a view illustrating a baffle according to the present invention. 6 is a perspective view illustrating a state in which a baffle is coupled to a baffle coupled reservoir cup according to the present invention and mounted to a fuel tank.

도 3 및 도 4에 도시된 바와 같이, 리저버 컵(51)의 측면으로 배플(53)의 가이드(53b)가 끼워질 수 가이드홈(51a)이 구비된다. 상기 가이드홈(51a)은 상기 가이드(53b)의 단면에 대응하는 형상으로 이루어져 상기 배플(53)이 고정체결될 수 있도록 한다.As shown in FIGS. 3 and 4, a guide groove 51a may be provided to guide the guide 53b of the baffle 53 to the side of the reservoir cup 51. The guide groove 51a has a shape corresponding to the cross section of the guide 53b so that the baffle 53 can be fixedly fastened.

본 발명의 실시예에서는 상기 가이드홈(51a)은 상기 리저버 컵(51)의 좌우 측면에 각각 위치하나 반드시 이에 한정되는 것은 아니며, 개수 또한 필요에 따라서 설계변경이 가능함은 물론이다. In the embodiment of the present invention, the guide grooves 51a are positioned on the left and right sides of the reservoir cup 51, respectively, but are not necessarily limited thereto, and the number and design may be changed as necessary.

도 5에 도시된 바와 같이, 배플(53)은 배플 플레이트(53a)의 하단부로 가이드(53b)가 구비되게 된다. 이를 보다 구체적으로 살펴 보면, 상기 배플 플레이트(53a) 및 상기 가이드(53b)는 프레스 공정을 통해 일체형으로 제작되며, 상기 가이드(53b)의 길이가 상기 배플 플레이트(53a)의 길이보다 길도록 한다.As shown in FIG. 5, the baffle 53 is provided with a guide 53b at the lower end of the baffle plate 53a. In more detail, the baffle plate 53a and the guide 53b are integrally manufactured through a pressing process, and the length of the guide 53b is longer than the length of the baffle plate 53a.

한편, 상기 가이드(53b)를 중심으로 좌우에 위치되는 상기 배플 플레이트(53a)가 서로 마주보는 구조가 되도록 상기 배플 플레이트(53a)를 상기 가이 드(53b)에 대하여 직각으로 접어서 이루어지도록 하며, 상기 배플 플레이트(53a)에는 연료의 유동을 위해 다수개의 구멍(53c)을 천공한다.Meanwhile, the baffle plate 53a is folded at right angles to the guide 53b such that the baffle plate 53a positioned at the left and right of the guide 53b faces each other. A plurality of holes 53c are drilled in the baffle plate 53a for the flow of fuel.

그러나, 반드시 이에 한정되는 것은 아니며, 실시예에 따라서는 상기 배플 플레이트(53a)는 상기 가이드(53b)를 중심으로 양측에 나란하게 위치할 필요는 없다. 즉, 상기 가이드(53b)를 중심으로 어느 한쪽으로만 위치되는 것도 가능하다.However, the present invention is not limited thereto, and according to an exemplary embodiment, the baffle plate 53a does not need to be positioned side by side on both sides of the guide 53b. That is, it is also possible to be located only on either side with respect to the guide 53b.

또한, 상기 배플 플레이트(53a)와 상기 가이드(53b) 사이의 각도를 조정하거나, 상기 가이드(53b)의 길이를 조정함으로써 다양한 형태의 배플(53)의 제작이 가능하다.In addition, various types of baffles 53 may be manufactured by adjusting the angle between the baffle plate 53a and the guide 53b or by adjusting the length of the guide 53b.

도 6에 도시된 바와 같이, 상기 리저버 컵(51)은 연료탱크(50)의 하부 플레이트에 고정체결되게 되며, 상기 리저버 컵(51)의 측면에 구비되어 있는 가이드홈(51a)에는 배플(53)의 가이드(53b)가 끼워짐으로써 배플(53)의 체결이 완료된다.As shown in FIG. 6, the reservoir cup 51 is fixed to the lower plate of the fuel tank 50, and a baffle 53 is provided in the guide groove 51a provided at the side of the reservoir cup 51. The fastening of the baffle 53 is completed by fitting the guide 53b of ().

한편, 유동음이 심하게 발생하는 곳에 대해서는 다른측 배플(53)과 위치를 변경하여 체결하거나, 다른 형태의 배플로 교체하는 등 유동음의 형태에 따라서 원하는 위치에 상기 배플(53)을 끼워 넣으면 되므로 배플 튜닝을 손쉽게 할 수 있게 된다.On the other hand, for the place where the sound is severely generated, the baffle 53 may be inserted at a desired position according to the shape of the sound, such as by changing the position with the other side baffle 53 or replacing it with another type of baffle. Baffle tuning becomes easy.

본 발명에 따른 배플 결합형 리저버 컵은, 배플의 고정을 위한 연료탱크 상단과의 용접작업이 필요 없게 됨으로써 부품의 원가절감은 물론, 연료탱크의 내구성을 증대시킬 수 있는 효과가 있다.The baffle coupled reservoir cup according to the present invention has the effect of reducing the cost of the parts and increasing the durability of the fuel tank by eliminating the need for welding with the upper end of the fuel tank for fixing the baffle.

또한, 배플을 리저버 컵의 가이드홈에 간단히 끼워 넣으면 체결이 이루어지므로 제작이 간단하고 제작시간이 단축될 수 있으며, 유동음 발생에 따라 배플을 교체하면 되므로 손쉬운 튜닝작업이 가능한 이점이 있다.In addition, if the baffle is simply inserted into the guide groove of the reservoir cup, the fastening is made, and thus the production is simple and the production time can be shortened.
