Along with the raising that development and the client of automotive electronics require automobile appearance, the light shape of motor vehicle illumination regulation to car headlamp is had higher requirement.The required design content considered of automobile lamp manufacturing industry becomes more, and difficulty has also become greatly.Wherein, headlamp regulation claims to the light shape of car headlamp again while being provided with the upper limit to some field of illumination brightness, requires must possess certain illumination in the dark space of vehicle front lighting light shape.Described requirement must possess the requirement of certain illumination in the dark space of vehicle front lighting light shape, see the marks such as the guideboard above road clearly for the ease of driver, require, in automobile headlight illumination region, there is the upper limit, to prevent the glare of driver causing opposing lane simultaneously.For reaching above-mentioned requirements, at present, adopt projecting unit headlamp Shi Ge great main engine plants to one of institute's trolley type large attraction.Each main engine plants are according to the difference of automobile type configuration, select the projecting unit of distance-light one or single function projection unit, and projecting unit can select dress two states light source, namely can xenon lamp (HID), also can use halogen tungsten lamp, but be no matter adopt which kind of state all must meet the requirement of ECE or GB to the regulation of dipped beam light shape and each luminous intensity distribution test point.But above-mentioned requirements has larger difficulty in design, careless slightly, will relevant laws and regulations be violated, cause product or listing can not to be postponed, time serious, can product recall be caused.
Summary of the invention
For above shortcoming, the utility model object is the anti-dazzle plate structure providing a kind of car headlamp projecting unit, the irregular body of two-layer different size is provided with by shadow shield assembly, respectively light filling is carried out to the dark space above dipped beam dead line, the light at 50L place to be reflected and scattering prevents 50L point light value excessively bright.
The technical scheme of the utility model technology is achieved in the following ways: a kind of anti-dazzle plate structure of car headlamp projecting unit, projecting unit is generally made up of bulb, speculum, shadow shield assembly, lens, support and trim ring, described shadow shield assembly is used for, in the projecting unit of car headlamp, being placed between light source reflector and lens carrier; It is characterized in that: the front end of described shadow shield is dead line cut out portion, dead line cut out portion rear end is shading light part, shading light part is provided with installation shaft, the upper surface of dead line cut out portion is provided with setting regions, setting regions is made up of two-layer irregular body not of uniform size, and little irregular body is positioned at large irregular body front end.
Dead line angle starting point a in the cut sides of described dead line cut out portion is positioned on primary optical axis, centered by dead line angle starting point a, the cut sides being positioned at left of center is provided with groove.
Boss is provided with in the middle of the upper surface of described shading light part at tail end place, after shadow shield is installed by installation shaft, and conflicted by the part of boss and projecting unit, ensure that the light that reflected by speculum is incident upon the dead line in front after the blocking of shadow shield clear.
Described shading light part is provided with the step surface of multiple concaveconvex shape.
Be provided with datum mark in the middle of described installation shaft, conveniently size detection carried out to shadow shield.
Described shadow shield is made up of aluminum alloy materials.
The utility model structure, structure is simple, easy for installation, the thin portion structure that shadow shield assembly requires for the formation of "cut-off"line and the auxiliary partial illumination realized in light shape dark space and clear zone of vehicle front lighting light shape, shadow shield is applicable to the projecting unit with halogen bulb, discharge bulb single function projection unit that is light source and distance-light one, be provided with groove by the cut sides place of dead line cut out portion and alleviate the dispersion of dipped beam dead line, improve comfortableness.

Fig. 3 is the top view of Fig. 2.
Fig. 4 is the structural blast schematic diagram of projecting unit.
In figure: 1 dead line cut out portion, 2 shading light parts, 3 installation shaft, 4 setting regions, 5 cut sides, 6 grooves, 7 positive stop lug boss, 8 datum marks.
Detailed description of the invention
Known by Fig. 1, Fig. 2, Fig. 3, a kind of anti-dazzle plate structure of car headlamp projecting unit, it is characterized in that: the front end of described shadow shield assembly is dead line cut out portion 1, dead line cut out portion 1 rear end is shading light part 2, shading light part 2 is provided with installation shaft 3, the upper surface of dead line cut out portion 1 is provided with setting regions 4, setting regions 4 is made up of two-layer irregular body not of uniform size, little irregular body is positioned at large irregular body front, is strengthened the illumination of the dark space above dipped beam dead line by the large irregular body in setting regions; Carry out reduction by the illumination of the little irregular body in setting regions to 50L test point place and prevent that some place luminous intensity distribution value is excessively bright here.Dead line angle starting point a in the cut sides 5 of dead line cut out portion 1 is positioned on primary optical axis, centered by dead line angle starting point a, the cut sides 5 being positioned at left of center is provided with groove 6, be provided with groove 6 by the cut sides place of dead line cut out portion 1 and can alleviate the dispersion of dipped beam dead line, improve comfortableness.And be provided with positive stop lug boss 7 in the upper surface centre of shading light part 2 at tail end place, after shadow shield assembly is installed by installation shaft 3, and it is inconsistent with other part of projecting unit by positive stop lug boss 7, dead line cut out portion 1 is met to the distance of bulb, thus the dead line that guarantee is incident upon front by the light that speculum reflects after shadow shield assembly blocks is clear.Also in the middle of installation shaft (3), be provided with datum mark (8), conveniently the size of shadow shield assembly detected by setting up of datum mark (8).Described shadow shield assembly is made up of aluminum alloy materials can be high temperature resistant, shading light part (2) on it is provided with the step surface of multiple concaveconvex shape, can be strengthened shadow shield assembly structure by step surface, also can expand area of dissipation by increasing area, accelerating heat radiation.
Known by Fig. 4, it is the structural blast schematic diagram of projecting unit, projecting unit is made up of bulb, speculum, shadow shield assembly, lens, support and trim ring etc., and shadow shield assembly is used for, in the projecting unit of car headlamp, being placed between light source reflector and lens carrier; The light of speculum reflection is incident upon front and forms dead line after shadow shield blocks, in addition on speculum some light reflection to the setting regions place on shadow shield, again by the large irregular body reflection in setting regions last by lens by above light refraction to horizontal line, to strengthen the illumination of the dark space above dipped beam dead line; Carry out reduction by the illumination of the little irregular body in setting regions to 50L test point place and prevent that some place luminous intensity distribution value is excessively bright here.
