Description
Technical field
The utility model is related to a kind of shading board mounting structure unit for vehicle lamp, more particularly to one kind to be applied to
The shading board mounting structure unit of the vehicle head lamp with double light PES, belongs to car light technical field.
Background technology
In for motor vehicle headlamp, often there is a kind of light-emitting lamp list being made up of light source, reflecting surface, lens and baffle plate
Unit, is commonly called as PES.This PES can be divided into single dipped beam, single distance light and distance-light one PES.And distinguish different functionalities
Exactly a kind of part for serving as baffle arrangement of the structure of PES units, i.e., so-called shadow shield.
Shadow shield is a kind of controlling organization of the quantity of the luminous flux for being controlled in lamp unit and being projected from light source.According to screening
Light board mounting structure, PES can be divided into single feature PES (single dipped beam or single distance light) and double light PES.Wherein shadow shield is with fixation
The PES that form is installed is monochromatic light PES, and the PES for carrying the shadow shield that can be moved or rotate is double light PES, and double light PES can
To realize distance-light function.Shading board mounting structure unit in double light PES plays very important role in light fixture.This
It is often, using motor type magnetic valve, to be driven by the torque produced after solenoid valves and hidden to plant shading board mounting structure unit
The movement or rotation of tabula rasa, so that the mutually purpose of switching between realizing nearly distance light.
Currently, the forms of motion of shadow shield mainly has two kinds.One kind be it is mobile, will one end of shadow shield be articulated with a water
On flat axle, the other end can do the rotation of 180 degree in perpendicular around the axle, by controlling the motion of the other end (due to work
Dynamic scope less, is approximately straight path) luminous flux that light source is projected is controlled so as to carry out two kinds of functions of distance-light；Another kind is
Rotate, the torque produced after being passed through electric current allows shadow shield to be overturn towards the direction that light advances, and distance light is obtained by upset
Light type and reverse flip realize that distance-light switches.
For the shading board mounting structure unit of mobile form, shadow shield is moved up and down in perpendicular, due to shading
This part of plate is on focal position, and general temperature is higher, so shadow shield typically uses metalwork, it is contemplated that the spirit of motion
Activity, it is too thick that shadow shield will not do, and its upper and lower spacing during up and down motion and be all metal parts, so far and near
When light switches metal and metal bump will caused by larger noise, therefore bring inadaptable sense to human pilot.And for
The shading board mounting structure unit of rotation formula, the shading board mounting structure unit that (i.e. optical axis direction) overturns for example forward, by
In the carrying out overturn forward with shadow shield, it is farther with the distance of light source, so in order to avoid it shuts out the light, usual shading
The angle that plate overturns forward can be bigger relative to the angle that shadow shield is turned over, that is, the magnetic valve being attached thereto must be able to produce
Bigger driving force, magnetic valve must do more work(, will correspondingly produce the problem of cost increase, while shadow shield motion
Distance is big, and efficiency of movement is also low.
