Description
Technical field
The utility model relates to car light technical fields, and in particular to a kind of LED automobile headlamp distance-light rotary switching mechanism.
Background technique
Car headlamp at present, generally using the car light of remote/close one, this kind of car light includes shading piece and driving mechanism.
Shading piece is set between vehicle lamp light source and optical lens, and the device of driving mechanism is made of electromagnet, the generation of electromagnet
Driving force makes shading piece rotate around the axis, thus the light for issuing light opened or blocked by shading piece to be formed it is remote/close
The irradiation of light；Far/dipped beam, which converts the mode mostly taken at present, to be turnover plate type or rotates cutting knife type, structure is complicated for these modes,
Component is more and occupied space is larger, and mechanics transmission is unstable is easy to appear stuck phenomenon.
Utility model content
For the defects in the prior art, the utility model provides LED automobile headlamp distance-light rotary switching mechanism, can
Realize the technical effect of the more smooth nearly high beam of switching, switching mechanism part is few, assembling procedure is simple, and yields is higher.
In order to achieve the above objectives, LED automobile headlamp distance-light rotary switching mechanism provided by the utility model, including heat dissipation
Device, light source, reflector, lens and switching mechanism；The light source is set on the radiator, and the reflector includes that dipped beam is anti-
Light bowl, the first distance light reflector and the second distance light reflector, the dipped beam reflector are set to above the light source, and described
The opening of dipped beam reflector is put to the lens side, and the first distance light reflector is set to opening for the dipped beam reflector
In front of mouthful, the second distance light reflector is set on the radiator below the first distance light reflector, the lens setting
In the front of the radiator；The light source is irradiated to the light of the dipped beam reflector, reflects by the dipped beam reflector
It is reflected away again by the lens afterwards；It is irradiated to the light of the first distance light reflector by the light source, successively passes through first
It is reflected away again by the lens after distance light reflector and the reflection of the second distance light reflector；The switching mechanism includes shading piece
And electromagnet, the shading piece include the barn door in front of the second distance light reflector and the pendulum positioned at shading board ends
Arm, the end of the swing arm and the radiator are hinged, and the side wall of the swing arm is equipped with oval groove, and the iron core of the electromagnet is set
There is reset spring, the end of the iron core of the electromagnet is equipped with set bar, and the end of the set bar extends to the oval groove
Interior, the electromagnet drives the barn door to block or open light of the second distance light reflector to reflection from lens.
The technical principle and technical effect of this programme are as follows:
The light that this programme light source issues has two paths to launch, and the first paths are as follows: light source is irradiated to dipped beam
The light of reflector, light are reflected into lens by dipped beam reflector, and lens will be launched after light refraction；Second paths
As follows: light source is irradiated to the light on the first distance light reflector, reflects by the first distance light reflector and the second distance light reflector
Onto lens, lens will be launched after light refraction.
Barn door is equipped in front of the second distance light reflector, electromagnet generates magnetic force after being powered, magnetic force attracts iron core mobile
The elastic force of reset spring is overcome simultaneously, and the iron core of electromagnet is shunk；After electromagnet power-off, the magnetic force of electromagnet disappears, magnetic force pair
Reset spring, which restricts, to disappear, and reset spring drives the iron core of electromagnet to extend to original position.Electromagnet is powered or the process of power-off
The middle contraction or elongation for realizing iron core.The set bar of oval groove is extended to since the end of iron core is equipped with, while swing arm
End is hinged with radiator, and therefore, iron core will drive barn door to rotate with hinge joint, and then to the second distance light reflector to lens
The light realization of reflection is blocked or is opened.
When barn door opens light of the second distance light reflector to reflection from lens, the first paths that light launches outward and
Second paths can be opened, and light is more adequately launched very much, at this time as high beam；When barn door blocks second
To the light of reflection from lens, the second paths that light launches outward will be blocked to form "cut-off"line distance light reflector, this
When as dipped headlight.
Electromagnet passes through the ingenious cooperation of oval groove and set bar in this programme, and barn door is driven to block or open second
Distance light reflector, so that the state of entire switching mechanism changes, runs very smooth, no card to the path of reflection from lens light
Phenomenon；Switching mechanism part is few, assembling procedure is simple, and production efficiency can be improved, and reduces manufacturing cost, fraction defective, far and near
Light switching mechanism is installed in bracket, is not take up exterior space, so that headlight is small and exquisite, install convenient.
Further, the upper edge of the barn door is set as " Z " font, and the upper edge of barn door is that light blocks edge,
" Z " font is set herein, makes it that can form "cut-off"line under dipped headlight mode as orthodox car headlight, so that row
Cross Cheng Gengjia safety.
Further, the end of the swing arm is connected to the side wall of a shaft, and the shaft is rotatably assorted with the radiator,
It is provided hingedly by shaft for swing arm, so that the more stable smoothness of the integrally rotated process of shading piece.
Further, the radiator includes several cooling fins, more preferable using cooling fin heat dissipation effect.
Further, the lens are fixed by bracket and the radiator, lens can be more stably fixed to prop up
In front of frame.
