Abstract

A kind of motor vehicle that can satisfy is not required to unscrew the integral type capless filler tube of the direct fuel up of fuel door.Rifle fuel up is directly mentioned it is characterized in that having and being not required to unscrew fuel door, control standard of six standard of GB18352 state that satisfaction national ecological environment portion issues about refueling process intermediate fuel oil discharge of steam avoids fuel steam discharge pollution and inflammable and explosive accident；And more sections of grafting standardized designs are used, make technique, simplify the structure, product quality is more reliable and more stable, reduces production cost.

Description

Integral type capless filler tube

Technical field

The invention patent relates to a kind of motor vehicle integral type capless filler tubes.It is characterized in that this integral type capless filler tube is adopted With more sections of plug-in type standardized designs and manufacture, the feature standardizes mould group and filling conduit 2, oil filling pipe by capless filler tube The components grafting such as plug 3, bracket 4, return tube 5 composition；The capless filler tube standardization mould group is by with fixed mounting hole The mechanisms such as oil filling pipe oral area 1, static conductive metal cover 6, capless fuel filler lid 7, diversion trench 8 are constituted；In the mouth of the capless fuel filler lid 7 The bottom in portion and diversion trench 8 is arranged the sealing that can unidirectionally open and close being made of sealing cover 9/10 and reset spring 11/12 and ties Structure；When lifting refueling nozzle, static conductive metal cover 6 is passed through, the top cover labyrinth 9 of capless fuel filler lid 7 is pushed open, continues into refueling nozzle and push away It convinces the lower sealing cover 10 of chute 8 by patient analysis, realizes and directly refuel without unscrewing fuel door；When fuel filling terminates, refueling nozzle is extracted, on Lower sealing cover 9/10 automatically resets sealing under the effect of spring 11/12, reaches the mesh that rifle oiling is directly inserted without unscrewing fuel door 's；Since all parts of oil filling pipe use more sections of plug-in type standardized designs and manufacture, manufacturing cost is made to be greatly reduced and save About production equipment facility is put into.

Background technique

According to six discharge standard of GB18352 state that national ecological environment portion promulgates, in stringent limiting vehicle refueling process Fuel steam discharge and air conservation；In addition current motor vehicle oil filling pipe is made of oil filling pipe and fuel door, filling combustion It is time-consuming and laborious that fuel door need to be unscrewed when oily, and after unscrewing fuel door, there are fuel-steam volatile emission phenomenons, cause to atmosphere The pollution of environment and it is be easy to cause inflammable and explosive accident, this is that six standard of state strictly limits；And manufacturing process is complicated, cost It is high.

Summary of the invention

In order to so that motor vehicle is met six discharge standard of GB18352 state and fuel up do not need to unscrew fuel door and Make simple oil filling pipe manufacturing process, reliable in quality and save the cost；The invention patent provides a kind of integral type capless filler tube, should Integral type capless filler tube is not only able to satisfy six discharge standard of GB18352 state, avoids refueling process intermediate fuel oil discharge of steam to ring Border pollutes and solves the problems, such as that fuel up needs to unscrew fuel door, and can solve oil filling pipe manufacturing process complexity and at high cost The problem of.The invention patent solves technical solution used by its technical problem: whole oil filling pipe is used by capless fuel filler The more sections of standardized designs such as pipe standards mould group, filling conduit, oil filling pipe plug, return tube, bracket and grafting assembly, And in capless fuel filler spout part be arranged with closure diversion trench and capless fuel filler lid, static conductive metal cover be integrally formed formula without Lid oil filling pipe；To reach structure simple type identifier, without unscrewing the direct fuel up of fuel door and avoiding refueling process intermediate fuel oil Discharge of steam pollutes problem.

Detailed description of the invention

Figure of description 1 is the left view of the invention patent, and Fig. 2 is the main view of the invention patent, and Fig. 3 is of the invention special The cross-sectional view of sharp main view, Fig. 4 are the structural exploded views of the invention patent.

Specific embodiment

The specific embodiment of the invention patent is: oil filling pipe is used into more sections of plug-in type standardized designs and manufacture, Oil filling pipe is designed to be made of capless fuel filler pipe die group, filling conduit, oil filling pipe plug, return tube, bracket, and adds in uncovered The diversion trench of setting with closure and capless fuel filler lid, static conductive metal cover are constituted in oil pipe oral area；When lifting refueling nozzle, pass through Static conductive metal cover pushes the top cover labyrinth of capless fuel filler lid open, continues into the lower sealing cover that refueling nozzle pushes diversion trench open, realizes It directly refuels without unscrewing fuel door；When fuel filling terminates, extraction refueling nozzle, upper-lower seal lid is answered automatically under the action of the spring Position sealing filling conduit.

Claims

1. a kind of motor vehicle integral type capless filler tube；It is characterized in that: this integral type capless filler tube uses more sections of plug-in type marks Standardization designs and manufactures, and the feature standardizes mould group, filling conduit, oiling pipe fitting, return tube, bracket group by capless fuel filler At；The capless fuel filler standardization mould group is by the oil filling pipe oral area with fixed mounting hole, diversion trench, capless fuel filler lid, static conductive Metal lid mechanism is constituted, and in the bottom of the diversion trench and the oral area of capless fuel filler lid, is arranged by reset spring and sealing cover structure At can unidirectionally open and close sealing structure；When lifting refueling nozzle, static conductive metal cover is passed through, pushes the upper of capless fuel filler lid open Sealing cover continues into the lower sealing cover that refueling nozzle pushes diversion trench open, realizes and directly refuels without unscrewing fuel door；When fuel oil plus Note terminates, and extracts refueling nozzle, and upper-lower seal lid automatically resets under the action of the spring seals filling conduit, reaches without unscrewing oiling Lid directly inserts the purpose that rifle refuels, and the pollution of refueling process intermediate fuel oil discharge of steam and inflammable and explosive accident is effectively avoided to occur；By In using more sections of plug-in type standardized designs and manufacture, manufacturing cost is greatly reduced.

2. integral type capless filler tube according to claim 1, feature has above-mentioned by capless fuel filler standardization mould group It is formed with filling conduit 2, oil filling pipe plug 3, bracket 4, return tube 5；The capless fuel filler standardization mould group is pacified by band is fixed Oil filling pipe oral area 1, diversion trench 8, capless fuel filler lid 7, the static conductive metal cover 6 for filling hole are constituted, in the mouth of the capless fuel filler lid 7 The bottom in portion and diversion trench 8 is arranged the sealing that can unidirectionally open and close being made of sealing cover 9/10 and reset spring 11/12 and ties Structure；When lifting refueling nozzle, static conductive metal cover 6 is passed through, the top cover labyrinth 9 of capless fuel filler lid 7 is pushed open, continues into refueling nozzle and push away It convinces the lower sealing cover 10 of chute 8 by patient analysis, realizes and directly refuel without unscrewing fuel door；When fuel filling terminates, refueling nozzle is extracted, on Lower sealing cover 9/10 automatically resets under the effect of reset spring 11/12 and seals filling conduit, realizes direct without unscrewing fuel door The purpose (such as Figure of description) of fuel up.
