The specific embodiment
Describe the present invention in conjunction with specific embodiments in detail below with reference to accompanying drawing.
With reference to figure 1～Fig. 3, the present invention is a kind of metal fuel tank static guiding device, comprising: fuel tank hanger, be connected with vehicle frame, and be used for the support metal fuel tank; Rubber cushion blocks is arranged between described metal fuel tank and the described fuel tank hanger, and described rubber cushion blocks has the accommodation space for installing fixing elements, and described rubber cushion blocks is fixed on the described fuel tank hanger by described tightening member; The electrostatic prevention pad, be arranged in the described accommodation space, described electrostatic prevention pad comprises fixed part and the elastic portion that is extended to form by described fixed part, described elastic portion and described metal fuel tank Elastic Contact, and described fixed part is fixed on the described fuel tank hanger by described tightening member; Wherein, the static charge of described metal fuel tank accumulation is directed to described vehicle frame through described electrostatic prevention pad and described fuel tank hanger.Further, described electrostatic prevention pad is Z-shaped schistose texture; Angle between described elastic portion and the described fixed part is acute angle; The top of described elastic portion is the rounding limit; Described rubber cushion blocks is the high and middle low shape in two ends, and described accommodation space is arranged on the two ends of described rubber cushion blocks; Described accommodation space is groove, is provided with through hole in the middle of the described bottom portion of groove, and through hole and the through hole on the described fixed part that described tightening member passes described groove successively are pressed abd fixed on the described fuel tank hanger; Described fixed part directly is connected described fuel tank hanger upper surface; Described electrostatic prevention pad is the chromium metallic material; The upper edge of a little higher than described accommodation space in described elastic portion top after fixing; Described 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, middle design has 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 by tightening member (as metal bolts 7).Be provided with accommodation space 31(such as the 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 reaching the bottom that touches 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, to prevent this metal fuel tank 2 that weares and teares.
Fig. 2 is electrostatic prevention pad 1 erection plan scheme drawing.Elastomeric electrostatic prevention pad 1 is fixed on the fuel tank hanger 4 together by metal bolts 7 after being positioned over rubber cushion blocks 3 top.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 that electrostatic prevention pad 1 closely contacts with metal fuel tank 2, 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 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 simultaneously.
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 at 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, avoided effectively taking place because of the accident that the poly-charge discharge of metal fuel tank face area may cause.
The above only is 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.
