Two wheeler backsight mechanismTechnical field
The present invention relates to a kind of two wheeler accessory, particularly a kind of two wheeler backsight mechanism.
Background technology
Two wheeler backsight mechanism (being rearview mirror) is as the important feedback tool in motorcycle driving process, energyEnough reflect the wagon flow situation of motorcycle rear, side and below, be convenient to driver and see intuitively these cars clearlyThe situation of stream position, expansion driver's field range, for driver's traffic safety provides safeguard. ExistingTwo wheeler backsight mechanism generally comprise mirror shell and be located at the speculum in mirror shell, mirror shell is adopted made of plastic;The rearview mirror of this structure due to mechanical strength and anti-wear ability poor, after long-time use, easily weares and teares,In the service life of having reduced rearview mirror, increase use cost.
Therefore, just a kind of two wheeler backsight of needs mechanism, it has larger mechanical strength and friction resistant ability,Effectively reduce wear condition, extend its service life, reduce use cost.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of two wheeler backsight mechanism, it has larger machineTool intensity and friction resistant ability, effectively reduce wear condition, extends its service life, reduces use cost.
Two wheeler backsight of the present invention mechanism, comprises the mirror shell being made of metal and is located at the speculum in mirror shell;The outer surface of described mirror shell is provided with wearing layer group, described wearing layer group by from the interior basal layer setting gradually outward,Intermediate layer and enhancement Layer composition, described basal layer is the carbide layers of thickness 1.5 μ m-3.0 μ m, described inInterbed is the nickel dam of thickness 0.6 μ m-1.2 μ m, and described enhancement Layer is the nitrogenize of thickness 2.0 μ m-4.0 μ mBoron layer.
Further, the position that is positioned at speculum top on described mirror shell is provided with the LED lamp for throwing light on.
Further, the thickness of described basal layer is 2.5 μ m.
Further, the thickness in described intermediate layer is 0.9 μ m.
Further, the thickness of described enhancement Layer is 3.0 μ m.
Beneficial effect of the present invention: two wheeler backsight of the present invention mechanism, because mirror shell adopts metal material systemBecome, larger mechanical strength, and the outer surface of mirror shell is provided with wearing layer group, can effectively strengthen its friction resistantAbility, effectively reduces wear condition, extends its service life, reduces use cost; In wearing layer group, basePlinth layer can stop mirror shell surface metal to be penetrated in intermediate layer and enhancement Layer, and intermediate layer can make enhancement Layer haveEffect deposition, enhancement Layer is wear-resisting, corrosion-resistant, difficult drop-off, environmental protection, and abrasion resistance is good; Basal layer, centreLayer and the thickness range of enhancement Layer are all determined by experiment, can realize wear-resisting in conservation, carryHigh working (machining) efficiency.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of wearing layer group of the present invention.
Detailed description of the invention
Fig. 1 is structural representation of the present invention, and Fig. 2 is the structural representation of wearing layer group of the present invention, asShown in figure: the two wheeler backsight mechanism of the present embodiment, comprises the mirror shell 1 being made of metal and be located at mirror shell 1In speculum 2; The outer surface of described mirror shell 1 is provided with wearing layer group, and described wearing layer group is by complying with outward from interiorBasal layer 31, intermediate layer 32 and the enhancement Layer 33 of inferior setting form, and described basal layer 31 is thickness 1.5 μThe carbide layers of m-3.0 μ m, described intermediate layer 32 is the nickel dam of thickness 0.6 μ m-1.2 μ m, described reinforcementLayer 33 is the boron nitride layer of thickness 2.0 μ m-4.0 μ m; Basal layer 31, intermediate layer 32 and enhancement Layer 33 canAdopt as the case may be physical vapour deposition (PVD) (PVD) method, chemical vapour deposition (CVD) (CVD) method and theyCombination and variation method apply; Because adopting metal material, makes on mirror shell 1, larger mechanical strength,And the outer surface of mirror shell 1 is provided with wearing layer group, can effectively strengthen its friction resistant ability, effectively reduce wearing and tearingSituation, extends its service life, reduces use cost; In wearing layer group, basal layer 31 can stop mirror shell1 surface metal is penetrated in intermediate layer 32 and enhancement Layer 33, and intermediate layer 32 can make enhancement Layer 33 effectively heavyLong-pending, enhancement Layer 33 is wear-resisting, corrosion-resistant, difficult drop-off, environmental protection, and abrasion resistance is good; Basal layer 31, centreLayer 32 and the thickness range of enhancement Layer 33 are all determined by experiment, can realize save in wear-resisting formerMaterial, improves working (machining) efficiency; Preferably, the thickness of described basal layer 31 is 2.5 μ m, described intermediate layer 32Thickness be 0.9 μ m, the thickness of described enhancement Layer 33 is 3.0 μ m, experiment shows, this one-tenth-value thickness 1/10 energyEnough realize the optimization of machining status.
In the present embodiment, the position that is positioned at speculum 2 tops on described mirror shell 1 is provided with the LED for throwing light onLamp 4; LED lamp 4 connects the headstock of motor by wire, headstock is provided with the switch of controlling LED lamp 4; ?Night is by bike time, turns on LED lamp 4 and puts and just can on speculum 2, see motorcycle road surface after one's deathSituation, the danger of reduction driving process.
Finally explanation, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, althoughWith reference to preferred embodiment, the present invention is had been described in detail, those of ordinary skill in the art should be appreciated thatCan modify or be equal to replacement technical scheme of the present invention, and not depart from technical solution of the present inventionAim and scope, it all should be encompassed in the middle of claim scope of the present invention.
