Description
Technical field：
The present invention relates to vehicle lamp field more particularly to a kind of car light can the nearly distance light system regions of light-changing type.
Background technology：
For a long time, car bulb is always the single illuminations of purposes.It is limited by technological means, car light illumination optical
It can not realize changeable illuminating effect.Single headlight hot spot can not also successfully manage a variety of different road conditions.Such as：Even
Unlatching dipped beam still but is possible to generate other drivers dazzling in city, and distance light is opened on highway can generate to it
His vehicle is dazzling but the illumination performance of dipped beam is insufficient for operator demand after closing distance light.
On the market there are two types of traditional headlight light distributing methods：One kind forms dipped beam dead line by reflecting surface, and another kind is logical
Barn door is crossed light type is blocked to be formed by line.But both the above design method in the case of design typification just
Cannot change be generated to optical effect again.This also results in the unicity of illuminating effect.The dipped beam light type of reflecting surface headlight is cut
Only line is realized by carrying out curved surface control to reflecting surface each region.The dead line of the light type of traditional module design method
It is then to be determined by the shape of barn door.Once design typification in both the above design method, optical property is also just fixed up,
It is also no longer changed during actual user's use.
The content of invention
The present invention provides a kind of shading roller type module, by the way that light-blocking member is changed to idler wheel by original baffle, solves
The certainly big monistic problem of lamplight type.Meanwhile carry the design module headlight for vehicles can be driver bring it is good
Driving experience.
The present invention basic technical scheme be：Light-blocking member in headlight for vehicles is idler wheel, on the periphery of the idler wheel
It is divided into several mutually independent regions along idler wheel rotation direction, each region sets different light-shielding structure face types, often
A light-shielding structure face type corresponds to different light ray cut lines respectively, the rotation position of idler wheel described in motor control.Motor can
It is directly connected to idler wheel or is connect indirectly by worm and gear.In this patent, light-shielding structure is changed to shading by barn door
The dead line formed after idler wheel is also upgraded to various shapes by single shape, and the number that can generate cut-off wire shaped depends on horse
The precision that Danone is enough realized.360 degree on idler wheel outer surface may serve to make stop surface, if the running accuracy of idler wheel is
Positive and negative 5 degree, then an idler wheel can realize the variation of 36 kinds of light type.Precision is higher, and the light type that it can be realized variation is more.Light type
The specific distribution order of state according to designer can arrange.
Based on above-mentioned basic technical scheme, the periphery upper edge rotor shaft direction of idler wheel is divided into the region of five, five areas
Domain is set respectively for side grades of backroads of Country, light grades of urban roads of Town, Motorway grades of highways,
Distance light and the light-shielding structure face type without dazzling distance light dead line.Above-mentioned Country side grades of backroads, Town light
Grade urban road, Motorway grades of highways, distance light and the light-shielding structure face type without dazzling distance light dead line belong in itself
The prior art, not in the protection domain of this patent.
Idler wheel allows to rotate forward or invert around axis.The appearance situation of each different light type depends on the feedback of vehicle body.
It is specific that there are two types of major class:1st, vehicle body has sensor, such as camera, camera identification surface conditions feedback signal drive motor
Rotation special angle makes idler wheel rotate to specific light type.2nd, the variation of light type is determined by speed, and each vehicle speed intervals correspond to one
A optical states.
Based on above-mentioned technical characteristic, vehicle body setting road camera is fed back according to the condition of road surface road that camera captures
Signal drive motor rotates.
Based on above-mentioned technical characteristic, automotive interior setting velocity sensor is rotated according to speed feedback signal drive motor.
In order to solve the problems, such as that big lamplight type is monistic, this patent proposes the design that barn door is designed as to shading idler wheel
Method designs different face types so as to realize when idler wheel is rotated to difference by the different zones on shading idler wheel circumference
Light type generates corresponding variation during position.Light type variation is mainly reflected in the change of dead line, because the change of dead line will
Directly affect the illumination performance in remote position.It will according to speed and vehicle sensor information, motor in vehicle travel process
Idler wheel can be driven to rotate to different location.So as to generate the light type suitable for different road conditions.Beneficial effects of the present invention are：
1st, a variety of variations of light type can be realized
2nd, a variety of light type can be suitable for different road surface variations
3rd, can be that driver brings better illuminating effect to experience
4th, the technology sense point of whole lamp or even vehicle is promoted.
Description of the drawings

Specific embodiment
In the prior art, dipped beam dead line depend on reflecting surface 1 principle schematic see Fig. 1, dipped beam dead line depends on
The principle schematic of barn door 2 is shown in Fig. 2.As depicted in figs. 1 and 2：The dead line of the dipped beam light type of reflecting surface headlight is by right
Reflecting surface each region carries out curved surface control to realize.The dead line of the light type of traditional module design method is then by barn door
Shape determined.Once design typification in both the above design method, optical property is also just fixed up, and actual user uses
It also no longer changes in the process.
Fig. 3 to Fig. 7 is in the present invention, motor will drive idler wheel to rotate to different location.It is suitable for difference so as to generate
The light type of road conditions.Fig. 3 is shown under light grades of Town, urban road road conditions, and headlamp uses this shading roller type module
When, horizontal dead line 3 generally -0.57 degree.Fig. 4 is shown under side grades of Country, backroad road conditions, headlamp
During using this shading roller type module, 45 degree of dead line 3 is generated, left side horizontal cut line drops to -0.57 degree.Fig. 5 be
Motorway grades, under Freeway Conditions, when headlamp uses this shading roller type module, generate 45 degree of dead line 3, left side
Horizontal cut line drops to -0.23 degree.Fig. 6 is the situation schematic diagram of no dead line in the case of distance light.Fig. 7 is without dazzling distance light
Schematic diagram.
The variation of light type, core carry out the division of different zones, each area on idler wheel entirety circumference in the design of idler wheel
Domain corresponds to a light type feature, and the design of the light-shielding structure face type in region determines the different variations of dead line.As shown in figure 8,
The circumference of idler wheel is divided into five regions, wherein Town light grades, side grades and Motorway grades of Country in the design
Between can be excessive peripheral curved.
A kind of scheme for implementing to provide to the present invention above is discussed in detail, for those of ordinary skill in the art, foundation
The thought of the present embodiment, in specific embodiments and applications there will be changes.In conclusion the content of the present specification
It should not be construed as limiting the invention, all any changes made according to design philosophy of the present invention are all in protection scope of the present invention
Within.
