Embodiment 1

[0037] refer to figure 1 and figure 2 , The light adjustment device for automobile headlights includes a shading plate 1 , a lamp socket 2 and an adjusting mechanism 3 for adjusting the angle of the shading plate 1 . The lamp holder 2 is provided with a second installation opening 20 , and the second installation opening 20 penetrates through the lamp holder 2 . The lamp socket 2 is provided with an adjustment shaft 21 penetrating the second installation opening 20 , and the central axis of the adjustment shaft 21 is perpendicular to the opening direction of the second installation opening 20 .

[0038] The two ends of the adjusting shaft 21 are respectively coaxially and fixedly connected with the clamping shaft 211. The cross-sectional contour of the clamping shaft 211 in the radial direction is in the shape of a long strip, an ellipse or a polygon. The cross-sectional profile is elongated, and the two clamping shafts 211 are rotatably connected to the lamp socket 2 . Wh...

Embodiment 2

[0054] refer to Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that the return mechanism 4 includes a return seat 43 and a return coil spring 44. The return seat 43 is provided with a positioning hole 431, which is located on the first side of the adjustment shaft 21 away from the adjustment driven gear 32. The flanges of the two connecting pipes 23 are clamped in the positioning holes 431 .

[0055] refer to Figure 5 and Image 6 , the return seat 43 is provided with a transmission assembly 45 . The transmission assembly 45 includes a transmission gear ring 451 , a driving planetary gear 452 disposed coaxially with the transmission gear ring 451 , and a plurality of transmission planetary gears 453 arranged around the driving planetary gear 452 . The transmission gear ring 451 is an inner gear ring and is fixedly connected to the return seat 43 . The transmission gear ring 451 and the adjusting shaft 21 are coaxially arranged.

Abstract

The invention relates to a light adjusting device for an automobile headlamp. The device comprises a light shielding plate and a lamp holder used for installing the light shielding plate; the light shielding plate is rotationally connected to the lamp holder, and the lamp holder is provided with an adjusting mechanism used for adjusting rotation of the light shielding plate; the adjusting mechanism comprises an adjusting driving gear, an adjusting driven gear meshed with the adjusting driving gear and an adjusting driving part used for driving the adjusting driving gear to rotate, wherein the adjusting driving gear is fixedly connected to the driving end of the adjusting driving part, and the adjusting driven gear is connected to the light shielding plate. The space occupied by the light adjusting device can be effectively reduced.

Description

technical field [0001] The present application relates to the field of automotive lighting devices, and in particular, to a light adjustment device for automotive headlights. Background technique [0002] Car lights refer to the lamps on the vehicle, which are the tools for the vehicle to illuminate the road at night, and also the prompt tool to issue various vehicle driving signals. Among them, the car headlight is the main lighting tool, which mainly includes a light source, a reflector, a shading plate and an optical lens. The reflector is an ellipsoid, the light-emitting center of the light source is set at the near focus of the ellipsoid reflector, the light emitted by the light source is reflected by the ellipsoid reflector and concentrated near the far focus of the ellipsoid reflector, and the shading plate is set at the ellipsoid reflector At the far focus of the mirror, a quasi-parallel light illumination light shape with a cut-off line of light and dark is finally...
