Definitions
- the present invention relates to a fuel tank, and more particularly to a fuel tank to which an in-tank fuel pump is applied.
- Patent Document 1 discloses a configuration in which a fuel tank having an opening for inserting and fixing a fuel pump in a top plate is provided with an annular rib around the opening.
- Patent Document 1 still has room for improvement in terms of rigidity against force applied from the radial direction of the opening.
- An object of the present invention is to solve the above-described problems of the prior art and to provide a fuel tank that can increase the rigidity against force applied to the opening of the fuel pump from the radial direction.
- the present invention provides a fuel tank (1) having a bottom plate (6) provided with an opening (5) for inserting and fixing a fuel pump (11).
- a first feature is that a linear radial rib (7) is provided around the opening (5).
- the bottom plate (6) is provided with an annular rib (9) surrounding the opening (5), and the radial rib (7) is orthogonal to the annular rib (9). has a second feature.
- At least two radial ribs (7) are provided, and the radial ribs (7) are arranged at symmetrical positions with respect to the center of the opening (5). has the characteristics of
- the fourth feature is that the four radial ribs (7) are arranged at regular intervals in the circumferential direction.
- female screw members (12) into which bolts for fixing the fuel pump (11) are screwed are arranged on the bottom plate (6) at regular intervals in the circumferential direction. ) is disposed between the female screw members (12).
- said bottom plate (6) is provided with an annular annular rib (9) surrounding said opening (5), said radial rib (7) being aligned with said annular rib ( 9), it is possible to improve the rigidity around the opening, particularly against radial force.
- said radial ribs (7) are provided at least two times, said radial ribs (7) being arranged symmetrically with respect to the center of said opening (5). Therefore, by arranging the radial ribs at symmetrical positions across the opening, it is possible to eliminate unevenness in rigidity.
- four radial ribs (7) are provided, and the four radial ribs (7) are arranged at regular intervals in the circumferential direction, so that the rigidity around the opening is increased. can be improved evenly.
- each female screw member (12) into which bolts for fixing the fuel pump (11) are screwed are arranged on the bottom plate (6) at regular intervals in the circumferential direction. Since two radial ribs (7) are arranged between the female screw members (12), the rigidity around the opening can be uniformly improved, and the female screw member is arranged radially inward. becomes possible.
- FIG. 1 is a left side view of a fuel tank according to one embodiment of the present invention.
- FIG. It is a bottom view of a fuel tank. It is an enlarged view of a baseplate. It is a perspective view around a baseplate.
- FIG. 1 is a left side view of a fuel tank 1 according to one embodiment of the invention.
- 2 is a bottom view of the fuel tank 1.
- FIG. A fuel tank 1 for storing liquid fuel such as gasoline is constructed by joining together an upper half body 3 and a lower half body 13 made of press-molded steel plates or the like.
- a filler port 2 is provided on the upper surface of the upper half body 3 .
- a pair of left and right front stays 4 for supporting the fuel tank 1 to the vehicle body are provided at the front end of the lower half 13 , and a rear stay 10 is provided at the rear end of the upper half 3 . ing.
- a bottom plate 6 having a circular opening 5 into which an in-tank fuel pump 11 is inserted and fixed is provided at a position near the rear of the lower half 13 .
- An annular rib 9 having a thin annular shape is provided around the opening 5 of the bottom plate 6 .
- Four linear radial ribs 7 orthogonal to the annular rib 9 are provided inside the annular rib 9 in the radial direction.
- a female screw hole 8 for fixing the fuel pump 11 to the bottom plate 6 is provided between the radial ribs 7 .
- a cylindrical female threaded member 12 having a female threaded hole 8 for fixing the fuel pump 11 is welded to the rear surface (upper surface) of the bottom plate 6 .
- FIG. 3 is an enlarged view of the bottom plate 6.
- FIG. 4 is a perspective view around the bottom plate 6.
- Each of the annular rib 9 and the radial rib 7 is a protrusion formed by press molding.
- the annular rib 9 is provided on the outer diameter portion of the bottom plate 6 , and the four radial ribs 7 are orthogonal to the annular rib 9 and extend radially inward.
- the radial ribs 7 are arranged at equal intervals of 90 degrees and symmetrical with respect to the center of the opening 5 .
- the radial rib 7 according to this embodiment has a substantially U-shaped cross section.
- the female screw member 12 is formed of a cold header bag nut and welded to the bottom plate 6 by projection welding.
- the bottom plate 6 of the fuel tank 1 has an annular rib 9 surrounding the opening 5 and a linear radial rib perpendicular to the annular rib 9. 7 is provided, it becomes possible to improve the rigidity around the opening, particularly against force from the radial direction.
- At least two radial ribs 7 are provided, and the radial ribs 7 are arranged at symmetrical positions with respect to the center of the opening 5 . By disposing 7, it is possible to eliminate unevenness in rigidity.
- the four radial ribs 7 are provided, and the four radial ribs 7 are arranged at equal intervals in the circumferential direction, so that the rigidity around the opening can be improved evenly.
- female screw members 12 to which bolts for fixing the fuel pump 11 are screwed are arranged on the bottom plate 6 at equal intervals in the circumferential direction, and four radial ribs 7 are arranged between the female screw members 12. Therefore, the rigidity around the opening can be improved evenly, and the female screw member can be arranged radially inward.
- the shape and structure of the fuel tank, the shape and structure of the bottom plate and opening, the shape and arrangement of the annular ribs and radial ribs, etc. are not limited to the above embodiments, and various modifications are possible.
- the cross-sectional shape of the radial rib may be a U-shape, a half-moon shape, a triangle shape, or a corrugated shape in which a semi-circle vibrates vertically.
