Background technology
Hybrid vehicle is due to the particularity of himself power system, and the fuel-steam pressure that its fuel tank inside is produced will far above the fuel tank of orthodox car.The fuel tank internal pressure of orthodox car is generally between-2.5KPa ~ 10KPa, and the pressure of hybrid power fuel tank inside is then between-30KPa ~ 38KPa, and therefore hybrid power fuel tank needs to have higher rigid requirements than conventional fuel oil case.Plastic fuel tank, owing to limiting by himself material mechanical performance, often needs to increase certain supporting construction in its fuel tank inside, could meet hybrid power fuel tank height rigid requirements.
Traditional supporting construction utilizes bar or plate one class rigid construction often, fuel tank inside top surface and bottom surface is coupled together, thus improves fuel tank structure rigidity.Although above-mentioned rigid connection structure can significantly improve fuel tank rigidity, then because fuel tank end face and bottom surface are rigidly connected, when fuel tank deforms under internal pressure effect, its internal rigid supporting construction is except will bearing the xial feed of fuel tank internal pressure generation, also bear because oil tank body is out of shape the addition bend load of asymmetric generation, above-mentioned addition bend load can produce the larger stress deformation in local at rigidity supporting structure and the inner connecting end surface edge of fuel tank, thus when the axial strength of rigidity supporting structure is not fully utilized, its connecting end surface just there occurs and has torn inefficacy.
Utility model content
The purpose of this utility model is, overcomes problems of the prior art, provides a kind of and has flexible high pressure fuel case supporting construction, can, under the prerequisite improving fuel tank rigidity, make supporting construction self avoid bearing larger addition bend load.
For solving above technical matters, a kind of high pressure fuel case supporting construction with flexibility of the present utility model, comprise the disk welded mutually with roof and the diapire of plastic fuel tank respectively, the inner end surface of described disk is interconnected by strut bar, and described strut bar is provided with the necking part that diameter is less than other position.
Relative to prior art, the utility model achieves following beneficial effect: roof and the diapire of plastic fuel tank are interconnected by strut bar, improve the Rigidity and strength of plastic fuel tank, the intensity at strut bar necking down position is lower than other position, and there is certain flexibility and deformability, can adapt to the deformation of fuel tank under internal pressure effect, thus make supporting construction avoid when axial strength is not fully utilized, its connecting end surface just tears inefficacy in advance.
As preferred version of the present utility model, the large-diameter portion of described strut bar is identical with the external diameter of described disk, and the necking part external diameter of described strut bar is 0.3 ~ 0.7 times of the external diameter of described disk.
As preferred version of the present utility model, described necking part is provided with twice, and necking part lays respectively at the position that described strut bar is connected with described disk.The enlarged diameter section of this structure is long, and necking part is positioned at the root at the upper and lower two ends of strut bar, and rigidity is relatively strong, and elasticity is relatively weak.
As preferred version of the present utility model, described necking part is provided with multiple tracks, and each described necking part is uniformly distributed along the axis of described strut bar.Enlarged diameter section and the necking part of this structure are arranged alternately, and rigidity is relatively weak, and elasticity is relatively strong.
As the further preferred version of the utility model, each described necking part is connected by circular arc smooth transition with adjacent large-diameter portion respectively.
As preferred version of the present utility model, described necking part is that scroll extends along the periphery of described strut bar.The necking part that the necking part intensity extended in scroll is arranged higher than multiple tracks, has good elasticity simultaneously.
As preferred version of the present utility model, described strut bar is hollow tubular structures, and the uniform wall thickness at each position.The main force part of shaft is outer wall, and center stressed is very little, and hollow tubular structures both can save material, can keep intensity again.
As preferred version of the present utility model, described disc face is densely covered with multiple numb spot-like projections respectively to the outer face of plastic fuel tank inwall.Fiber crops spot-like projections adds the bonded area with inner wall of oil tank, improves anchoring strength.
