The invention relates to the technical field of motor vehicle illumination, in particular to an external light-dimming motor of an automotive headlamp. The external light-dimming motor comprises a motor, a motor worm, an intermediate drive lever, a spiral gear, a casing, a light-dimming lever, manual-adjusting bevel gears and a drive bevel gear, wherein the motor worm is arranged on an output shaft of the motor; the intermediate drive lever is provided with a turbine part and a worm part, the turbine part is meshed with the motor worm, and the worm part is meshed with the spiral gear; a thread is formed in an inner hole of the spiral gear, threads are formed in an inner hole and the peripheral surface of the casing, and the spiral gear is spirally nested on the peripheral surface of the casing; a ball head is arranged at one end of the light-dimming lever, a thread part is formed in the middle of the light-dimming lever, and multiple raised lines extending in the axial direction of the light-dimming lever are arranged at the other end of the light-dimming lever; the casing is spirally nested at the thread part of the light-dimming lever; the drive bevel gear comprises a conical tooth part and a connecting part, the conical tooth part is meshed with the manual-adjusting bevel gears, and long grooves matched with the raised lines are formed in an inner hole surface of the connecting part. The external light-dimming motor of the automotive headlamp has both electric adjusting and manual adjusting functions, and the layout is reasonable.
Description
technical field [0001] The invention relates to the technical field of motor vehicle lighting, in particular to an external dimming motor for an automobile headlamp. Background technique [0002] The front lighting of the car is listed as one of the safety parts of the car by the country, and the dimming motor, as a part of the front lighting of the car, is one of the important components for the headlight to meet the lighting requirements and ensure the safety of vehicles at night. According to the requirements of the mandatory standard GB4785-2007 "Installation Regulations for Exterior Lighting and Light Signal Devices of Automobiles and Trailers", low-beam headlights must be equipped with dimming devices, which clearly stipulates that dimming motors must be installed on lamps. At present, the manual adjustment method of the dimming motor is single, which cannot be determined according to the customer's use method, which brings inconvenience to the customer. [0003] The ...
