Description
Technical field
The present invention relates to a kind of drive device, particularly a kind of vehicle head lamp dimming drive device.
Background technology
Front car light illumination angle is the important parameter of car light light beam adjustment, directly influences traffic safety.Existing vehicle head lamp, either manual setting or electronic adjustment is required for a light modulation point to drive dimming mechanism.Due to most of light modulation points the centres of gyration and the light modulation screw mandrel centre of gyration not on the same line, the space that making dimming drive device will have relative motion is driven, drive disk assembly can deviously bypass the purpose that various barriers reach remote transmission gyration, other parts in car light installation site and vehicle on some vehicles, vehicle body etc. is limited by space structure, the tune light spot position that can be set on car light is extremely limited, the tune light spot position of setting may raise light screw mandrel position and produce skew with car light, need the steering adjustment mechanism of some complexity of design, cause complex structure, transmission efficiency is low and high cost.
The content of the invention
Limited by space structure to solve existing front truck lamp dimming device, the tune light spot position of setting may raise light screw mandrel position and produce skew with car light, need the steering adjustment mechanism of some complexity of design, cause complex structure, transmission efficiency is low and problem of high cost, the present invention provides a kind of vehicle head lamp dimming drive device, light modulation can be set at car light back cover housing any one place and drive point, is delivered to torsion on light modulation screw mandrel along back cover housing curved surface by flexible drive axle by adjustment torque, to realize dimming purpose.
Therefore, the technical scheme is that：A kind of vehicle head lamp dimming drive device, including light modulation screw mandrel, it is characterised in that：Also include Flexible Transmission axle assembly, one end of Flexible Transmission axle assembly is Hard link end, and the other end of Flexible Transmission axle assembly is the end that is flexible coupling；The afterbody for dimming screw mandrel is equipped with dynamic bevel gear, the Hard link end of Flexible Transmission axle assembly is provided with preceding mounting bracket, the end that is flexible coupling of Flexible Transmission axle assembly is provided with rear mounting bracket, drive bevel gear is connected by preceding mounting bracket with the Hard link end of Flexible Transmission axle assembly, and cross adjustment joint is flexible coupling to hold with Flexible Transmission axle assembly and is connected by the endoporus of rear mounting bracket；Drive bevel gear is engaged with dynamic bevel gear；The end that is flexible coupling is Bowden cable, and peripheral hardware damping flexible pipe.When using, the present invention is by preceding mounting bracket, that rear mounting bracket is installed on car light rear casing is external.
Further restriction to above-mentioned technical proposal：Flexible Transmission axle assembly Hard link end is a drive link, and drive link stretches into the endoporus of preceding mounting bracket, and the end of drive link is connected with drive bevel gear；Drive link is in preceding mounting bracket by axial limiting.
Further restriction to above-mentioned technical proposal：The soft of Flexible Transmission axle assembly, Hard link end can need to carry out anteroposterior dimension adjustment according to arrangement, specially：The Linear transmission section extended back from light modulation screw mandrel end is Hard link end, and remaining transmission segment is the end that is flexible coupling.
Further restriction to above-mentioned technical proposal：Flexible Transmission axle assembly is externally provided with protection tube.
Beneficial effect：The present invention takes soft or hard connection soft drive mode, the external any locus of headlamp rear casing can be conveniently disposed at, using flexible connection at curved surface and obstacle, used at plane and straight line and be rigidly connected, it is flexible coupling outside the Bowden cable at end and damping flexible pipe is set, transmission efficiency is lost caused by Bowden cable flexural deformation when can prevent from adjusting lamp to exert a force, and improves whole drive mechanism transmission efficiency.Light modulation screw mandrel on light modulating device is driven by Flexible Transmission axle assembly, the illumination angle of car light is adjusted.Also, simple structure, moment of torsion is big, transmission efficiency.
