Background
The fuel pump for automobile is a basic component of fuel injection system for electronic injection automobile, and has the functions of sucking fuel from fuel tank, pressurizing and conveying fuel to fuel supply pipe, and the fuel pump is matched with fuel pressure regulator to build certain fuel pressure.
Traditional car oil tank generally is equipped with the valve body that realizes oil tank steam management function, and the flange and the oil storage bucket of fuel pump generally are coaxial setting, still are equipped with in the middle of flange and the oil storage bucket and refuel the limit valve, and refuel the limit valve and fix on the flange, but along with whole car arrange the compactification of design, arrange that the limited size that leads to leaving for the oil tank direction of height diminishes in space, the structural arrangement of traditional fuel pump can not adapt to the design requirement of all motorcycle types or operating mode. In order to solve the problem, the flange of the fuel pump and the oil storage barrel can be arranged in a staggered mode, so that the flange and the oil storage barrel are connected in an eccentric mode, and the oil filling limit valve is also deviated from the position right above the oil storage barrel. However, after the fuel pump is installed in the fuel tank, the flange is pressed downwards, and the fuel storage barrel is easy to slide obliquely after being pressed by the flange, so that the position of the fuel level sensor connected with the fuel storage barrel is changed therewith, and the fuel level in the fuel tank cannot be accurately measured by the fuel level sensor.
Disclosure of Invention
The utility model aims to provide a: the fuel tank with the fixed position of the eccentric fuel pump is provided for solving the problems that the eccentric fuel pump in the prior art is unstable in position and easy to topple.
In order to realize the purpose of the utility model, the utility model provides a following technical scheme:
the utility model provides an eccentric fuel pump rigidity's fuel tank, includes the fuel tank body, the first side wall of fuel tank body is seted up and is supplied eccentric fuel pump to penetrate and the fixed mounting hole, the flange and the oil storage bucket of eccentric fuel pump are eccentric form and link to each other, the flange runs through the mounting hole, the second side wall butt of oil storage bucket bottom and fuel tank body, first side wall and second side wall set up relatively, this internal and the second side wall that is located of fuel tank is formed with the locking structure, the locking structure be used for preventing rocking of oil storage bucket and with the side butt of oil storage bucket.
Adopt above-mentioned technical scheme the utility model discloses, be provided with detent structure on the fuel tank body, detent structure and the side butt of oil storage bucket can prevent the perk behind the overdraft that receives the flange bottom the oil storage bucket for the stability of oil storage bucket in the use can strengthen, has reduced rocking of the oil level sensor position that links to each other with the oil storage bucket, has strengthened the degree of accuracy of oil level sensor to oil tank interior oil volume feedback.
Further, the stopping structure is a protrusion formed on the second side wall toward the interior of the fuel tank body. The stop structure is a bulge formed on the second side wall, so that the stop structure is convenient to machine, additional workpieces do not need to be added, and the light-weight design concept is met.
Further, the stop structure is formed on the opposite side of the flange deviating from the oil storage barrel, or is enclosed around the side edge of the oil storage barrel. The stop structure can be arranged to partially surround the flange at the opposite side deviating from the oil storage barrel, or can be arranged to surround the oil storage barrel in a closed mode at the circumferential direction, so that the position stability of the oil storage barrel can be improved.
Further, the fuel tank is in a concave pit structure at the position abutting against the oil storage barrel. The pit-shaped structure can play a role in positioning the installation of the eccentric fuel pump and can also reduce the shaking of the oil storage barrel of the eccentric fuel pump.
Furthermore, the shape of the pit-shaped structure is matched with the shape of the bottom surface of the oil storage barrel, or the pit-shaped structure is in a regular round shape. When the shape of the pit-shaped structure is matched with the shape of the bottom surface of the oil storage barrel, the pit-shaped structure can facilitate the installation of the eccentric fuel pump and has a positioning effect on the oil storage barrel; and the regular round pit-shaped structure is convenient to process, and the cost is reduced.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: be provided with the detent structure on the fuel tank body, the side butt of detent structure and oil storage bucket can prevent oil storage barrel head portion perk behind the overdraft that receives the flange for the stability of oil storage bucket in the use can strengthen, has reduced rocking of the oil level sensor position that links to each other with the oil storage bucket, has strengthened the degree of accuracy of oil level sensor to oil tank interior oil volume feedback.
