When the filler cap switching device is opened, the difference value of the opening torque and the torque generated when slipping occurs during opening increases, the switching device is not prone to slipping, and use reliability is improved.
Description
Technical field
The utility model relates to a kind of auto parts and components, refers in particular to a kind of filler cap switching device.
Background technology
At present, existing filler cap switching device, filler cap is opened moment of torsion at 1.5 ~ 2.5N.M, closing torque is at 1.0 ~ 2.5N.M, but while opening, occur that the moment of torsion skidding generally do not stipulate in technical standard, through actual measurement, in about 4.5N.M, when opening moment of torsion with opening while occurring that the moment of torsion skidding approaches in opening process, just there is the risk of skidding in filler cap opening process in the moment of torsion that the appearance of filler cap is skidded.China Patent Publication No. CN101994446A, open day on March 30th, 2011, name is called in the patent of invention of " a kind of automobile oil filler cap guide device " and discloses a kind of automobile oil filler cap guide device, comprise filler cap inner panel, filler cap outside plate and oil filler box, described filler cap inner panel and described filler cap outside plate are fixedly connected into filler cap integral piece, described filler cap inner panel is installed hinge by filler cap and is flexibly connected with described oil filler box, it is characterized in that: between described filler cap inner panel and described oil filler box, be provided with a guiding mechanism, stability when described guiding mechanism guarantees oil filler cap system opening and closing, prevent that described filler cap integral piece is sagging and cross and open.Weak point is that this guide piece does not still limit for the moment of torsion skidding, and filler cap still easily skids while opening.
Utility model content
The purpose of this utility model is to overcome the defect that in prior art, in filler cap opening process, switching device easily skids, and the moment of torsion that provides a kind of increase to skid greatly reduces the filler cap switching device of switching device rich and influential family's risk.
The purpose of this utility model is to be achieved by following technical proposals:
A kind of filler cap switching device, comprise lid assembly and fuel lid housing assembly, lid assembly comprises lid and hub, hub is arranged on the lower end of lid, hub is provided with rotation tongue and hub spring, rotation tongue bottom surface is connected with one end of hub spring, and the end face of rotation tongue is and uneven inclined-plane, bottom surface; Fuel lid housing comprises housing and pressure valve, and pressure valve is located in housing, and pressure valve top is provided with pagoda spring and pressure valve spring, and pagoda spring and pressure valve spring are located on spring perch; In fuel lid housing, be also provided with the projection that several mate with rotation tongue.When filler cap switching device need to be closed, lid driven rotary tongue clockwise rotates, and the rotation inclined-plane of tongue and the protruding inclined-plane of housing contact, and housing clockwise rotates, and then rotates tongue contraction and skips behind housing inclined-plane, makes filler cap in closed condition; When filler cap switching device need to be opened, lid driven rotary tongue rotates counterclockwise, and the right angle face of rotation tongue contacts with protruding right angle face, and the moving housing of rotation lingual ribbon rotates counterclockwise, and filler cap is opened.When filler cap switching device need to be closed owing to being that inclined-plane contacts with inclined-plane, revolve control tongue shrink skip housing inclined-plane moment of torsion at 1N M-2.5 N M; Filler cap switching device is the face contact of Mian He right angle, right angle in the time of need to opening, hub spring is difficult for compressed, revolving control tongue shrinks and to skip moment of torsion that moment of torsion on housing inclined-plane skid more than 10 N M, and open the normal moment of torsion of opening of filler cap switching device, be no more than 2.5 N M, open moment of torsion and occur that with opening the moment of torsion difference of skidding becomes large, the possibility of skidding reduces greatly.
As a kind of preferred version, lid assembly also comprises for locating the space washer of hub position, and space washer one side contacts with lid, and another side contacts with hub.Space washer, for hub position is positioned, avoids hub position to occur deviation effects effect.
As a kind of preferred version, housing is also provided with seal ring outward.Seal ring is for the sealing of oil pipe oral area circular conical surface and switching device.
As a kind of preferred version, housing also comprises compressing tablet and cut-off packing ring, and compressing tablet is located on pressure valve spring, and cut-off packing ring is located under pagoda spring.
As a kind of preferred version, the quantity of projection is 6-8.
The beneficial effects of the utility model are, filler cap switching device, when opening, is opened moment of torsion and occurred that with opening the moment of torsion difference of skidding becomes large, and switching device is difficult for skidding, and has promoted the reliability using.
Accompanying drawing explanation
Fig. 1 is a kind of schematic cross-section of the present utility model.
Fig. 2 is the structural representation of housing of the present utility model.
Wherein: 1, pagoda spring, 2, pressure valve, 3, spring perch, 4, pressure valve spring, 5, compressing tablet, 6, hub spring, 7, seal ring, 8, housing, 9, rotation tongue, 10, lid, 11, space washer, 12, hub, 13, cut-off packing ring, 14, projection.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment: a kind of filler cap switching device, its schematic cross-section as shown in Figure 1, comprise lid assembly and fuel lid housing assembly, lid assembly comprises lid 10, hub 12 and space washer 11, hub is arranged on the lower end of lid, space washer one side contacts with lid, and another side contacts with hub.Hub is provided with rotation tongue 9 and hub spring 6, and rotation tongue bottom surface is connected with one end of hub spring, and the end face of rotation tongue is and uneven inclined-plane, bottom surface; Fuel lid housing comprises housing 8, pressure valve 2, compressing tablet 5 and cut-off packing ring 13, pressure valve is located in housing, pressure valve top is provided with pagoda spring 1 and pressure valve spring 4, pagoda spring and pressure valve spring are located on spring perch 3, compressing tablet is located on pressure valve spring, and cut-off packing ring is located under pagoda spring.Housing is also provided with seal ring 7 outward.The structural representation of housing as shown in Figure 2, is also provided with 6 projections 14 of mating with rotation tongue in housing.
