Abstract
The invention discloses a welding structure of a fuel tank installation base of a motorcycle frame. The welding structure comprises a left frame tube, a right frame tube and the fuel tank installation base. The left frame tube and the right frame tube are welded to the left end of the fuel tank installation base and the right end of the fuel tank installation base respectively. The fuel tank installation base is composed of a middle plate. The left end of the middle plate and the right end of the middle plate extend outwards respectively to form a left side plate and a right side plate. The left side plate is welded to the left frame tube 1. The right side plate is welded to the right frame tube. Two edges of the left side plate and two edges of the right side plate extend downwards respectively to form lower bent edges. The rear end of the middle plate extends upwards to form an upper bent edge. The middle plate is provided with an installation hole. According to the welding structure, because both sides of the fuel tank installation base have undergone edge folding treatment, the overall structural rigidity is higher, and the fuel tank installation base can bear a larger weight; besides, because the fuel tank installation base is well connected with the left frame tube and the right frame tube, a reinforcing effect on a partial structure is achieved; a fuel tank can be installed in the installation hole in the fuel tank installation base; because the back portion of the middle of the fuel tank installation base is folded up and has a limiting effect, an fuel tank installation bolt is prevented from being damaged by shear force.
Description
Technical field
The present invention relates to frame of motorcycle, refer more particularly to frame of motorcycle oil tank mounting seat welded structure.
Background technology
Fuel tank on frame of motorcycle is to be arranged on the frame tube of left and right by oil tank mounting seat, and traditional oil tank mounting seat is to adopt straight plate or some rod irons to be welded on the frame tube of left and right; Adopt straight plate to fix, its counter-bending power and twisting resistance are poor, easily produce distortion; And adopting dry rod iron to fix, fuel tank is inconvenient to install, and cost is higher, not firm.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point of the prior art, provide a kind of simple in structure, weld firm, difficult drop-off, practical novel frame of motorcycle oil tank mounting seat welded structure.
Frame of motorcycle oil tank mounting seat welded structure provided by the invention, comprise left frame tube, right frame tube, oil tank mounting seat, described left frame tube, right frame tube are welded in respectively on the two ends, left and right of oil tank mounting seat, its oil tank mounting seat is made up of middle plate, and the two ends, left and right of middle plate stretch out respectively and form left side board and right side board; Described left side board and left frame tube 1 weld; Described right side board and the welding of right frame tube; The both sides of described left side board and right side board extend to form respectively lower crimp downwards; The rear end of described middle plate upwards extends to form crimp; Described middle plate is provided with mounting hole.
Adopted above structure, the present invention has following beneficial effect:
It is better that flange processing total rigidity has all been done on the welded oil tank mounting seat of frame of motorcycle oil tank mounting seat of the present invention both sides, more can bear weight, and well link together with left and right frame tube, reinforcement effect has been played in part, mounting hole on oil tank mounting seat can be installed fuel tank, oil tank mounting seat rear middle part, to upper overturning, plays position-limiting action, prevents that fuel tank hold-down bolt is subject to shearing force and destroys.
Brief description of the drawings
In order to be illustrated more clearly in the present invention, below will be to by reference to the accompanying drawings embodiment being briefly described.
Fig. 1 is the welded schematic diagram of frame of motorcycle oil tank mounting seat of the present invention;
Fig. 2 is Fig. 1 birds-eye view.
Detailed description of the invention
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Referring to accompanying drawing 1,2, frame of motorcycle oil tank mounting seat welded structure of the present invention, comprise left frame tube 1, right frame tube 2, oil tank mounting seat 3, left frame tube 1, right frame tube 2 are welded in respectively on the two ends, left and right of oil tank mounting seat 3, oil tank mounting seat 3 is made up of middle plate 4, the two ends, left and right of middle plate 4 stretch out respectively left side board 5 and the right side board 9 of formation " Z " font; Left side board 5 welds with left frame tube 1; Right side board 9 welds with right frame tube 2; The both sides of left side board 5 and right side board 9 extend to form respectively lower crimp 6 downwards; It is better that flange processing total rigidity has all been done on left side board 5 and right side board 9 both sides, more can bear weight, and well link together with left frame tube 1, right frame tube 2, and reinforcement effect has been played in part; The rear end of middle plate 4 upwards extends to form crimp 7, plays position-limiting action, prevents that fuel tank hold-down bolt is subject to shearing force and destroys; Middle plate 4 is provided with mounting hole 8, facilitates the installation of fuel tank.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
