Abstract
The utility model provides a destination disk, include: a quotation supports with being used for for the light beam the supporter of quotation, the quotation is including at least two -layer superimposed surface course layer upon layer, and from outside to inside is protective layer and reflection stratum respectively, the protective layer is made by optical filtering ya keli, be equipped with the measurement dot on the reflection stratum. Through above -mentioned scheme, set the quotation to the layering setting, utilize optical filtering ya keli material to filter the visible light to stopped the interference that the dot was measured on to destination disk to the visible light, improved measurement accuracy, and simple structure has made easily.
Description
Technical field
This utility model is related to testing equipment field, refers in particular to a kind of destination disk.
Background technology
With economic growth, the recoverable amount of automobile is in continuous propradation, and the after-sales service of automobile, become vast
The difficult problem of vehicle owner.Automobile because of load, the rotating speed difference of each wheel, defines the inclined of wheel after long-duration driving
Turn, now, it is necessary to which four-wheel aligner is carried out to wheel.Four-wheel aligner be with the four-wheel parameter of vehicle as foundation, by adjust with
Guarantee the good driving performance of vehicle and possess certain reliability.
Installation between the steered wheel of automobile, knuckle and front axle three is with certain relative position, this to have
The installation of certain relative position is called steered wheel positioning, also referred to as front wheel alignment.Front wheel alignment includes reverse caster (angle), stub
Introversion (angle), four contents of front wheel camber (angle) and toe-in of front wheel.This is for two steering front wheels, for two trailing wheels
Similarly there is the relative position installed and rear axle between, claim trailing wheels.Trailing wheels include camber (angle) and one by one
Trailing wheel toe-in.
However, the combination of destination disk and photographing unit is adopted mostly for the detection means of four-wheel aligner instantly, will target
Disk is fixed on wheel hub, the perspective phenomenon formed when wheel is deflected using the round dot on destination disk, is carried out by photographing unit
It is measured from out.But this destination disk is existed and is easily affected by visible ray so that photographing unit cannot accurately measure lacking for round dot
Point.Based on this, a kind of destination disk not affected by visible ray how is proposed, be the problem of urgent need to resolve in the industry.
Utility model content
The utility model proposes a kind of destination disk, to solve the above problems.
What the technical solution of the utility model was realized in：
A kind of destination disk, including：Card for reflection light and the supporter for supporting the card；
The card includes the surface layer that at least two-layer is layering, from outside to inside respectively protective layer and reflecting layer, described
Protective layer is made up of optical filtering acrylic, and the reflecting layer is provided with measurement round dot.
Further, the supporter edge forms a cylinder in the supporter lower end then in arc transition, described
Cylinder lower end is provided with screw.
Further, some reinforcements are additionally provided with inside the supporter, and the reinforcement is in laterally or longitudinally to arrange, and institute
State reinforcement side and connect the card back side, opposite side connects the supporter.
Further, the reinforcement is arranged in grid.
Further, the card is rectangular, and corner is provided with chamfering.
The beneficial effects of the utility model are：By such scheme, card is arranged to into layering and is arranged, using Asia gram of filtering
Dead-wood matter filters visible ray, so as to prevent interference of the visible ray to measuring round dot on destination disk, improves certainty of measurement, and ties
Structure is simply easily fabricated.
Description of the drawings
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or accompanying drawing to be used is briefly described needed for description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work
Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.
Fig. 1 is a kind of dimensional structure diagram of destination disk one embodiment of this utility model；
Plan cross-section structural representations of the Fig. 2 for a kind of destination disk shown in Fig. 1.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
It should be noted that front, rear, left and right described below, both sides, both sides are not intended as to this utility model scope
It is any limitation as, but for preferably helping reader to understand this patent.
Referring to a kind of one embodiment of destination disk of this utility model shown in Fig. 1, Fig. 2, including card 1 and supporter 2.Disk
Face is used for reflection light, and supporter is used for supporting the card.
The card includes the surface layer that at least two-layer is layering, and in the present embodiment, surface layer is two-layer, is divided from outside to inside
Wei not protective layer 11 and reflecting layer 12.In other embodiments, or three layers, four layers are more, and such structure becomes
Change and still fall within protection domain of the present utility model.The protective layer is made up of optical filtering acrylic, is set on the reflecting layer
There is measurement round dot.Preferably, protective layer using high intensity optical filtering acryl plates and in addition process by vacuum ion sputtering technique.
Used as the further optimization to the present embodiment, the supporter edge is in arc transition then under the supporter
End forms a cylinder, and the cylinder lower end is provided with screw, to connect outside support.
Some reinforcements 21 are additionally provided with inside the supporter, and the reinforcement is in laterally or longitudinally to arrange, in this enforcement
It is horizontally set in example, the flatness to strengthen card can also be arranged using grid in other preferred embodiments, it is ensured that
Card occurs without the failure such as bending.And the reinforcement side connects the card back side, opposite side connects the supporter.
The card is rectangular, and corner is provided with chamfering, scratches people or car to the wedge angle for preventing rectangle.
By such scheme, card is arranged to into layering and is arranged, visible ray is filtered using optical filtering acrylic material, so as to shut out
Absolutely interference of the visible ray to measuring round dot on destination disk, improves certainty of measurement, and simple structure is easily fabricated.
Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in this utility model
Protection domain within.
