Above-mentioned technology all belongs to directly to adopt installs the mode that buckle fastener realizes the installation of vehicle fuel pipe.But in a vehicle of applicant's design, vehicle fuel pipe, when arranging, can have one section and pass through and the bending section in similar S shape from body bottom panel lower surface.Like this, be fixed iff the simple clamp of employing, then this part fuel pipe is exposed to outside, when running car road conditions are poor, easily be subject to the impact of the objects such as muddy water, dust, gravelstone grain, and then cause fuel pipe damaged, or fixing clamp damage causes fuel pipe to pull, and finally causes fuel leakage accident.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical matters to be solved by this invention is: how to provide a kind of structure simple, quick and easy for installation, the vehicle fuel pipe fixed protection structure good to fuel pipe protected effect.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
A kind of vehicle fuel pipe fixed protection structure, comprise and be positioned at frame panel lower surface and the bending fuel pipe in similar S shape, it is characterized in that, also comprise and be arranged at below fuel pipe and the guar plate of fuel pipe in the similar S shape of coupling, guar plate dual-side upwards bends rear formation installation seamed edge, be provided with multiple mounting hole in the middle part of guar plate along its length and be fixed on frame panel by attaching screw, and by fuel oil circumference of cannon bone between guar plate and frame panel.
In the present invention; have employed guar plate to be installed by fuel pipe and enclose on frame panel, guar plate forms better protection, and when preventing running car, the object such as muddy water, dust, gravelstone grain is to the impact of fuel pipe; improve fuel pipe protected effect, prevent fuel pipe damaged and reveal.Meanwhile, guar plate is connected and fixed installation by the screw at middle part, fixing reliable and quick and easy for installation.
As optimization, described installation seamed edge upper end-face edge has horizontally outer flange.
Like this, during installation, the flange of guar plate two lateral edges upper end contacts with frame panel, can improve installation stability, improves fuel pipe protection effect.Better selecting during enforcement is the setting of surface thereof 1-5 °, flange lateral, like this, can utilize the elasticity of flange better, improves the combination degree of flange and frame panel when attaching screw is fixed, and prevents from there is gap and producing vibration abnormal sound.
Further, described flange upper surface gummed is connected and is equipped with one deck rubber peel.Like this, by the elasticity of rubber peel, improve guar plate and frame panel compression degree, eliminate assemblage gap, avoid occurring assemblage gap between guar plate and frame panel and producing vibration abnormal sound.
As optimization, between described guar plate and frame panel also and fuel pipe be set side by side with canister adsorption tube.Like this, the protected effect to canister adsorption tube can be improved.
As optimization, described guar plate upper surface is furnished with the clamping arranged in pairs along fuel pipe length direction interval protruding, and described fuel pipe is connected and fixed between clamping projection.
Like this, after optimization, fuel pipe is connected and fixed between clamping projection, improves the fixed effect to fuel pipe, avoids fuel pipe to bounce between guar plate and collides and cause breakage and produce vibration abnormal sound.
Further, often pair of clamping projection, comprise one and upwardly connect bar to the stub of fuel pipe medium position along fuel pipe side, and a long clamping bar upwardly extending to fuel pipe tip position along fuel pipe opposite side in the middle part of fuel pipe again along fuel pipe surface bending curvature.
Like this, fuel pipe can lean on the elasticity of clamping projection self, and move ahead and snap onto between often pair of clamping projection, it is simple that clamping projection has structure, and fuel pipe is quick and easy for installation, and fix the advantages such as reliable and stable.
Further, described guar plate is also provided with an oil filter installation cavity to lower convexity along fuel pipe oil inlet end end position, and oil filter installation cavity is connected with fuel pipe oil inlet end for installing oil filter.The installation of oil filter can be facilitated like this to fix, make oil filter and fuel pipe connecting position be under guar plate protection simultaneously, avoid position herein receive foreign object strike and leak, there is better protected effect.
In sum, it is simple that the present invention has structure, quick and easy for installation, the advantage good to fuel pipe protected effect.
