Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel tank for a vehicle, and more particularly, to a fuel tank for a vehicle, which prevents rotation of the fuel pump when the fuel pump is mounted on a fuel cap, .
2. Description of the Related Art Generally, an engine of a vehicle is a device that converts thermal energy into mechanical rotational force by rotating a crankshaft using an explosive force generated by burning fuel in a combustion chamber.
In such an engine, fuel to be burned in the combustion chamber is continuously supplied, and a fuel tank capable of storing a certain amount of fuel in the vehicle is provided for continuous supply of fuel.
The fuel tank is provided with a fuel pump for supplying the fuel stored in the fuel tank to the engine of the vehicle. When the fuel pump is moved (rotational movement) when the fuel pump is mounted on the fuel tank, Tube or the like interferes with a structure (baffle or the like) inside the tank, which is disadvantageous in case of severe damage. Therefore, when the fuel pump is mounted, it is preferable to fix the fuel pump so as not to rotate.
Further, a sealing member for maintaining airtightness is provided between the fuel tank and the fuel pump so as to be in contact with the fuel pump. When the fuel pump is rotated during the mounting of the fuel pump, the rotation of the fuel pump causes the sealing member to twist, A twisting phenomenon occurs, and in this case, there is a disadvantage in that the sealing performance is lowered in a certain section of the sealing member, and leakage occurs.
It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.
The present invention relates to a fuel pump that prevents rotation of a fuel pump when the fuel pump is mounted on a fuel tank to prevent damage and breakage of the fuel pump and further prevents twisting of a sealing member provided between the fuel tank and the fuel pump, And a fuel tank for a vehicle which can further improve the performance of the fuel tank.
To achieve the above object, according to the present invention, there is provided a fuel tank for a vehicle, comprising: a stopper bracket fixed at one end to an upper plate and provided with a fuel tank hole formed in an upper plate to expose the other end; And a fuel pump in which a stopper hole is formed to insert the other end of the stopper bracket exposed to the fuel tank hole when the fuel pump is inserted and installed in the fuel tank hole.
Wherein the fuel pump includes a head portion exposed to the outside of the top plate and a skirt portion protruding downward from a bottom surface of the head portion; And a stopper hole opened downward is formed in the skirt portion.
A seating groove is formed in the upper plate around the fuel tank hole; A sealing member is installed in the seating groove; And the sealing member is pressed by the head portion of the fuel pump to maintain the airtightness between the top plate and the fuel pump.
The upper plate is fixedly coupled with a fixture having a male screw on the outer circumferential surface to receive the head portion and the sealing member of the fuel pump; Wherein the fixing hole is coupled with an opening nut having a female screw on an inner peripheral surface thereof; And a pressing part for fixing the fuel pump in contact with the head part of the fuel pump when the opening nut is coupled to the fixture is integrally bent at the inner end of the opening nut.
And a nut cover covering the opening nut to cover the opening nut.
And the rotation of the fuel pump is prevented by the other end of the stopper bracket inserted into the stopper hole when the opening nut is engaged with the fixture.
And the stopper bracket is welded to the bottom surface of the upper plate and is not exposed to the outside.
The stopper bracket includes a base portion welded in a superposed state on a bottom surface of the upper plate and extending horizontally along the upper plate; A bent portion formed in a step-like shape in an upward direction from an end of the base portion; And a stopper portion extending horizontally at an end of the bent portion and inserted into the stopper hole; Wherein the stopper portion is pressed by the skirt portion in a state of being inserted into the stopper hole when the fuel pump is installed; And the bent portion is elastically deformed downward when the stopper portion is pressed by the skirt portion.
According to the present invention, when the end portion of the stopper bracket fixed to the upper plate of the fuel tank is inserted into the stopper hole formed in the skirt portion of the fuel pump at the time of inserting the fuel pump into the fuel tank hole, the initial installation position of the fuel pump can be regulated It is possible to prevent rotation of the fuel pump by the stopper bracket inserted into the stopper hole when the opening nut is rotated to couple the opening nut to the fixture, thereby preventing damage and breakage of various electric wires and tubes connected to the fuel pump There is an effect that can be.
Further, according to the present invention, since the fuel pump does not rotate during the rotation coupling of the opening nut, the torsional twisting phenomenon of the sealing member can be eliminated, thereby further improving the sealing performance between the top plate of the fuel tank and the head portion of the fuel pump There is also an effect that can be improved.
Further, according to the present invention, when the fuel pump is installed in the fuel tank hole, the stopper portion and the bent portion of the stopper bracket are elastically deformed by the pressing of the skirt portion, and the sealing member is sufficiently pressurized by the head portion of the fuel pump Accordingly, the sealing member can exhibit a further improved sealing performance.
