The specific embodiment
Combine specific embodiment to specify the present invention with reference to accompanying drawing below.
With reference to figure 1～Fig. 3, the present invention is a kind of metal fuel tank static guiding device, comprising: fuel tank hanger, connect to ground, and be used for the support metal fuel tank; Rubber cushion blocks is arranged between said metal fuel tank and the said fuel tank hanger, and said rubber cushion blocks has the accommodation space that is used for installing fixing elements, and said rubber cushion blocks is fixed on the said fuel tank hanger through said tightening member; The electrostatic prevention pad; Be arranged in the said accommodation space; Said electrostatic prevention pad comprises fixed part and the elastic portion that is extended to form by said fixed part, said elastic portion and said fuel tank hanger Elastic Contact, and said fixed part is fixed on the said fuel tank hanger through said tightening member; Wherein, the static charge of said metal fuel tank accumulation is directed to said vehicle frame through said electrostatic prevention pad and said fuel tank hanger.Further, said electrostatic prevention pad is Z-shaped schistose texture; Angle between said elastic portion and the said fixed part is an acute angle; The Xiang Duanwei rounding limit of said elastic portion; Said rubber cushion blocks is the high and middle low shape in two ends, and said accommodation space is arranged on the two ends of said rubber cushion blocks; Said accommodation space is a groove, is provided with through hole in the middle of the said bottom portion of groove, and through hole and the through hole on the said fixed part that said tightening member passes said groove successively are pressed abd fixed on the said fuel tank hanger; Said fixed part direct connection is at said fuel tank hanger upper surface; Said electrostatic prevention pad is the chromium metallic material; The upper edge that said elastic portion item after fixing is held a little higher than said accommodation space; Said fuel tank hanger and fastener are metal.
In Fig. 1 a, Fig. 1 b, Fig. 1 c, disclosed the structural representation of a kind of elasticity electrostatic prevention pad of the present invention.This electrostatic prevention pad 1 comprises fixed part 12 and the elastic portion 11 that links together with this fixed part 12; This fixed part 12 is circular ring plate; The centre is designed with through hole 121; Be positioned over metal fuel tank 2 rubber cushion blocks 3 above, then, be fixed on (referring to Fig. 2) on the fuel tank hanger 4 together through tightening member (like metal bolts 7).Be provided with the accommodation space 31 (like groove) of upper shed in this rubber cushion blocks 3, have groove through hole 32 in the bottom of this accommodation space 31, the through hole 121 that this tightening member passes on groove through hole 32 and the fixed part 12 successively directly is pressed abd fixed on the fuel tank hanger 4; Wherein, fuel tank hanger 4 can support metal fuel tank 2 suspension types.
For making its bottom that can touch metal fuel tank 2 effectively, design a sharp angle in the short transverse of this electrostatic prevention pad 1, so that the generation of electrostatic prevention pad 1 elastic force distortion.Top 111 is the rounding limit, contacts with metal fuel tank 2, with anti-attrition this metal fuel tank 2.
Fig. 2 is electrostatic prevention pad 1 an erection plan scheme drawing.Elastomeric electrostatic prevention pad 1 is fixed on the fuel tank hanger 4 through metal bolts 7 after being positioned over rubber cushion blocks 3 top together.After a whole set of fuel tank installs; Because elasticity electrostatic prevention pad 1 height is a little more than rubber cushion blocks 3; Behind its stress deformation; Guaranteed electrostatic prevention pad 1 and metal fuel tank 2 closed contacts, realized that the metal fuel tank 2 that gets up with rubber pad " insulation " connects with non-the bumping property of mill of 4 on mailbox carriage, built a static flow-guiding channel simultaneously from metal fuel tank 2 → " Z " shape electrostatic prevention flow deflector 1 → metal bolts 7 → fuel tank hanger 4 → bracket plate 5 → vehicle frame 6.
Fig. 3 flows to scheme drawing for static charge water conservancy diversion on the fuel tank 2.Static charge in the metal fuel tank 2 vehicle frame 6 that leads in the direction of arrows is at last by vehicle frame 6 guiding the earth, static charge ground connection neutralization unnecessary on the metal fuel tank 2.
This device only needs to get final product by shown in Figure 2 being installed on the fuel tank hanger, for guaranteeing each metal fuel tank of safety two cover elasticity electrostatic prevention pads is installed.
The present invention relates to a kind of metal fuel tank static guiding device to oil supply system for vehicle.This device has been built " metal an is connected " passage by the specially made structure of a special spring leaf between metal fuel tank and fuel tank hanger; Realized the static charge of gathering in the metal fuel tank in the vehicle movement process is led away; Increased the safety of metal fuel tank greatly, the accident of having avoided effectively possibly causing because of charge discharge that metal fuel tank face area gathers takes place.
The above is merely preferred embodiment of the present invention, non-limitation protection scope of the present invention, and the equivalent structure that all utilizations specification sheets of the present invention and accompanying drawing content are done changes, and all is contained in protection scope of the present invention.
