Description

A kind of intelligence headlamp optical system

The present invention claims the Chinese invention patent Shens for application No. is 201710572370.6 applyings date being July 14 in 2017 A kind of please domestic priority of " intelligence headlamp optical system ".

Technical field

The present invention relates to a kind of self-adapting illumination device or the functional characters or components of its system, more particularly to by means of Adjust a kind of adaptive front lamp optical system that components change luminous characteristic and distribution.

Background technique

Traditional vehicle front lighting lamp system is mainly formed by block combiners such as dipped headlight, high beams, and light beam is all solid Fixed, light beam is fixed, and can only be operated with manual switches switching distance light, dipped beam to control irradiation distance and area and light Shape, realization have a single function, and there is shortcomings for traditional head lamp system in actual use, in vehicle night meeting process In, the other side Lai Che situation that high beam is normally opened can be encountered often, since high beam can make to generate wink on opposite Driver Vision Between blinding, the blinding time sustainable two seconds or so, within this two seconds time, driver drove as closed one's eyes, and there is very big Hidden peril of accident；When front vehicle opens high beam, it will appear large area halation in the interior outside rear-view mirror of front truck, it can shadow Front truck driver is rung from backsight sem observation rear situation, wherein having the preceding photograph of the optics module of projection microscope group currently on the market Lamp can realize distance-light simultaneously in a mould group, rely primarily on the monoblock type metal gear that built-in one piece has "cut-off"line Plate, or the fixed one end oscilaltion of overturning or one end is to 2 kinds of limiting conditions, respectively can only be to the deserved single dipped beam and remote realized Light.But the switching of single distance light and dipped beam state had both needed driver distraction to carry out manual operations, not only cannot timely change The dipped beam of partial region when the road Bian Qian illumination condition and simple distance light change as to(for) meeting illuminates insufficient.

For another example when high vehicle speeds, since irradiation distance is limited, influence driver to front obstacle can Depending on property, it cannot be guaranteed that safe stopping distance, reduces the active safety of vehicle driving, with electronic technology and car light science and technology Development, the concept of automotive self-adaptive headlamp are come into being, and adaptive vehicle light illumination system can be switched to according to condition of road surface Different light illumination mode, as highway mode, urban road mode, backroad mode, far lighting mode, distance light are automatic It is transformed to low beam mode.

Europatent EP2088364A1 describes a kind of adaptive dimming mechanism, by motor, wiring board, driving cog The parts compositions such as wheel, driving gear, shaft, bracket, fixed frame.Axle sleeve and driving gear are attached separately to the both ends of shaft, driving

Gear is fixed with shaft, can be rotated together with shaft by rotation center of axial line.Motor shaft, axle sleeve, sliding tooth Wheel, transmission gear and wiring board with bracket holder by being fixedly connected.

It dims principle: 1, the rotation angle of motor is controlled by wiring board.

, motor drive sliding tooth wheel and shaft to rotate a certain angle by transmission gear.

, pivot design at specific shape, shaft forms dead line of different shapes when rotating to different angle.

, light source assembly issue light a part blocked by shaft, remaining light is irradiated to road surface after lens subassembly, Its illumination light shape depends on the shape of dead line.The shape of dead line is also different when shaft is rotated to different angles, to reach To the purpose for the light shape for changing the light being irradiated on road surface.

However the shortcomings that above-mentioned light adjusting system, is:

1. the program is due to having the shaft of specific shape using integral type, section of different shapes is arranged in the difference of axis body Angle, but orthographic projection is still single shape and is through to entirety at the section of each angle, and optical imagery is because of its outgoing The reason of angle, is amplified to remote road surface, therefore being switched fast for different angle will be by the change of the big smooth shape of geometric grading Change speed, driver's human eye, which is limited by frequency variation, can experience the light shape and jump in brightness of the only step recognized, shadow Ring comfort.

For the program due to having the shaft of specific shape using integral type, section of different shapes is arranged in the difference of axis body Angle, but at the section of each angle orthographic projection be still single shape and be through to axis bus it is whole, therefore front The light deformation on road surface is the variation of large area, changes the illumination effects of road surface ahead very greatly, to extreme case inferoanterior road The safety that the vehicles or pedestrians in face identify and itself drives is defective.

The program provides more sections if necessary, then needs the shaft that diameter is bigger, the bigger design space of demand, And for Automobile Design, the mutual design space of components is especially limited.

The program provides more sections, and gentler transformation light shape if necessary, then then needing diameter bigger Gear is used to drive shaft, therefore the also bigger design space of demand.

The program provides more sections if necessary, then needs the shaft that diameter is bigger, and what it is according to projecting mirror car light is System optical Design, shaft size increases then entire cylindrical body, and 360 ° one of front and back border size increases up and down, then can block Rearview mirror shoots to some light of anterior lens, directly affects the illumination efficiency of overall optical system, the product after volume production Congenital design defect will be become.

Similar to other European patents of the program, the front using the specific convex shape manufacture in shaft is locally fixed Shade, with approaching for meeting, demand left-right rotation in meeting wherein rotates on one side or simultaneously the projection of the right and left Mirror mould group increases the bifurcated degree of road surface ahead shade and clear zone, and this scheme will will lead to script left and right headlamp optical system and fold The light added is dispersed by broadening, and then causes the brightness in the most desirable region for illuminating and not needing manufacture shade of road surface ahead straight Connect decline.

Similar to other European patents of the program, the front using the specific convex shape manufacture in shaft is locally fixed Shade, with approaching for meeting, demand left-right rotation in meeting wherein rotates on one side or simultaneously the projection of the right and left Mirror mould group increases the bifurcated degree of road surface ahead shade and clear zone, and this scheme will will lead to script left and right headlamp optical system and fold The light added is dispersed by broadening, and scattered light spreads to road surface, and other do not need too bright region, and then influence roadside Vehicle, driver, pedestrian and toy cause light interference or pollute and cause discomfort that partial region is extra.

Similar to other European patents of the program, the front using the specific convex shape manufacture in shaft is locally fixed Shade, with approaching for meeting, demand left-right rotation in meeting wherein rotates on one side or simultaneously the projection of the right and left Mirror mould group increases the bifurcated degree of road surface ahead shade and clear zone, therefore demand can provide the driving motor of left rotation and right rotation, and mould group Left rotation and right rotation demand headlamp lamp body marks off bigger rotary motion space, not only cost of idleness but also the clumsiness that seems.
