Abstract
The utility model discloses an oil filling pipe structure, and relates to the technical field of automobiles. The oil filling pipe structure comprises an oil filling pipe flange of an oil filler and an oil filling gun guiding support in an oil filling pipe, wherein the oil filling pipe flange and the oil filling gun guiding support can conduct electricity, and the oil filling gun guiding support is connected with the oil filling pipe flange. According to the oil filling pipe structure, the oil filling pipe flange and the oil filling gun guiding support which can conduct electricity are connected, and a conducting coating is added on the inner wall of the oil filling pipe, so that the oil filling pipe and a vehicle body form a reliable low-resistance unipotential access; and thus, static electricity generated in the processes of flowing, friction and the like of gasoline can be transferred and released quickly, spontaneous combustion caused by the discharge of the static electricity generated in the flowing process of gasoline can be prevented effectively, and the safety of the oil filling process is ensured.
Description
Technical field
The utility model relates to automobile technical field, relates in particular to a kind of fuel filler pipe structure.
Background technology
Along with spark ignition passenger car gets into family in a large number, its safety is more and more shown great attention to by people, and especially incident such as vehicle spontaneous combustion takes place repeatedly, and it is thorough in the design of fuel oil system, to need to consider.On fire in the refueling process is a kind of breakneck phenomenon; Because the fuel tank and the fuel filling pipeline of present manned vehicle generally adopt non-metallic material (like engineering plastics or rubber); Existing gasoline can produce a large amount of static charges in the process of flow at high speed, friction; The electric conductivity of non-metallic material is relatively poor, and these static charges are not as shift discharging at short notice, will be between nozzle and intraluminal fluid face the very high voltage of instantaneous generation and discharging; Cause fuel oil on fire and explosion caused, have very big danger.As shown in Figure 1; In existing filling conduit; Fuel filler pipe is fixed on the vehicle body panel beating through the fuel filler pipe flange 1 of the mouth of pipe, but and captive nut 3 places be provided with conductive rubber pad 2, but through this conductive rubber pad 2; Fuel filler pipe flange 1 can further be fixed on vehicle body, and realizes the equipotentiality low impedance path of oil filling port and vehicle body.But; But also have certain distance between nozzle support 4 in the fuel filler pipe pipe and the conductive rubber pad 2, form therebetween and open circuit, impedance can reach more than the megaohm; The static charge accumulation that the jet that refuels produces can cause producing the difference of potential of 10Kv, and (oil filling port is electronegative; Nozzle is positively charged), this electric potential difference can cause the generation (promptly producing jumper spark) of electrostatic discharge completely, discharges owing to can't realize the transfer of this static; Produce very high potential between the gasoline level in the refueling process in nozzle muzzle and pipeline, be easy to produce the spark discharge phenomenon and the explosion caused safety hazard that waits.
The utility model content
The technical matters that (one) will solve
The technical matters that the utility model will solve is: a kind of gasoline electrostatic prevention fuel filler pipe structure on fire in refueling process that prevents is provided.
(2) technical scheme
For addressing the above problem; The utility model provides a kind of fuel filler pipe structure; This fuel filler pipe comprises the fuel filler pipe flange of oil filling port and the nozzle guiding trestle in the fuel filler pipe; Said fuel filler pipe flange and said nozzle guiding trestle can conduct electricity, and said nozzle guiding trestle is connected with the fuel filler pipe flange.
Preferably, said fuel filler pipe inwall all scribbles conductive coating.
Preferably, said fuel filler pipe inwall scribbles conductive coating from said oil filling port to predeterminable range.
Preferably, said predeterminable range is in pipe, to extend 20-30cm from said nozzle guiding trestle away from the end of said oil filling port.
Preferably, said fuel filler pipe flange and said nozzle guiding trestle are processed by conductive material.
Preferably, said fuel filler pipe flange and said nozzle guiding trestle surface scribble conductive coating.
(3) beneficial effect
In the fuel filler pipe structure of the utility model; Conductive fuel filler pipe flange and nozzle guiding trestle link together; The fuel filler pipe inwall increases conductive coating in addition, makes fuel filler pipe and vehicle body form a failure-free low-resistance equipotentiality path, can gasoline is mobile, the static that produces in the process such as friction shifts release fast; Prevent that effectively the phenomenon of spontaneous combustion has guaranteed the safety of refueling process because gasoline produces electrostatic discharge in flowing.
Description of drawings
Fig. 1 is traditional fuel filler pipe structural profile scheme drawing;
Fig. 2 is the fuel filler pipe structural profile scheme drawing according to a kind of embodiment of the utility model.
The specific embodiment
The fuel filler pipe structure that the utility model proposes combines accompanying drawing and embodiment to specify as follows.
As shown in Figure 2; Comprise according to the fuel filler pipe structure of a kind of embodiment of the utility model: the fuel filler pipe flange 1 of oil filling port, the conductive rubber ring 2 on the fuel filler pipe flange 1, fuel filler pipe flange 1 and conductive rubber ring 2 be fixed in the captive nut 3 of vehicle body panel beating;, and fuel filler pipe in nozzle guiding trestle 4, fuel filler pipe flange 1 and nozzle guiding trestle 4 can conduct electricity, and nozzle guiding trestle 4 is connected with fuel filler pipe flange 1; Preferably, link together through melting welding.Like this; Fuel filler pipe flange 1 in the fuel filler pipe pipe, nozzle guiding trestle 4 and vehicle body form a failure-free low-resistance equipotentiality path; The static that can gasoline be flowed, produce in the process such as friction shifts release fast, thereby has avoided refueling the generation that waits safety hazard on fire.
Discharge the static that produces between the gasoline level in nozzle conducting bracket and the fuel filler pipe in order better to shift, the fuel filler pipe inwall is all or part of to scribble conductive coating (among the figure shown in the shade).When the fuel filler pipe inner wall section scribbled conductive coating, this part is preferably from the fuel filler pipe mouth of pipe to nozzle guiding trestle 4 ends extended 20-30cm (being not limited thereto) again in pipe.
In order to realize the purpose of the utility model, fuel filler pipe flange 1 can be processed by conductive material with nozzle guiding trestle 4.Perhaps; In order to save cost, in the fuel filler pipe structure of this embodiment, fuel filler pipe flange 1 can still be processed by non-metallic material with nozzle guiding trestle 4; For realizing its conduction, the surface of fuel filler pipe flange 1 and nozzle guiding trestle 4 scribbles conductive coating (among the figure shown in the shade).
Nozzle guiding trestle, oil filling port and the vehicle body of the fuel filler pipe structure of this embodiment is connected as a single entity and forms good equipotentiality low impedance path; Can make the static that produces in the refueling process shift release fast; Thoroughly avoid the refueling process generation that waits safety hazard on fire, guaranteed the safety of refueling process.
Above embodiment only is used to explain the utility model; And be not the restriction to the utility model; The those of ordinary skill in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also be made various variations and modification; Therefore all technical schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be defined by the claims.
