Abstract

The invention discloses a dimming device, casing and reflector connection structure of an automobile headlamp, which comprises a casing, a reflector, a horizontal adjusting assembly and a vertical adjusting assembly. The horizontal adjusting assembly comprises a horizontal adjusting screw and a ball seat, the vertical adjusting assembly comprises a vertical adjusting screw and an adjusting nut, and a horizontal adjusting support is connected between the horizontal adjusting screw and the ball seat. A first clamping groove is arranged in the casing, and the horizontal adjusting support and the first clamping groove are in clamping connection and can slide relative to each other. A vertical adjusting support and a dimming motor are connected between the vertical adjusting screw and the adjusting nut, the dimming motor is fixed in the middle of one lateral surface of the vertical adjusting support, a second clamping groove is arranged in the casing, and the vertical adjusting support and the second clamping groove are in clamping connection and can slide relative to each other. The connection structure can improve firmness of connection among the dimming device, the casing and the reflector, and can reduce powder leakage, falling off and other phenomena.
