Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a dimming motor which is easy to disassemble and assemble. Background Art

[0002] The car headlight dimming motor is a motor used to adjust the illumination angle of the car headlights. When the car passes through uneven roads and uphill and downhill slopes, the illumination ability of the road surface can be improved by adjusting the illumination angle. At the same time, when meeting other cars, the dimming motor can reduce the illumination angle of the headlights to prevent the lights from causing glare to the oncoming drivers. When the adjustment motor rotates, it will drive the screw to rotate, causing the ball head to move forward and push the reflector to change its angle.

[0003] In the prior art, the ball head of the dimming shaft will rotate with the rotation of the screw rod, but because the ball head is connected to the headlight or headlamp structure, the ball head is partially exposed during the rotation process, which can easily reduce the lubrication of the ball head connection and easily draw dust during driving into the rotating structure, affecting the light adjustment effect; when the existing dimming motor is fixed to the lamp housing, it is necessary to pre-set corresponding limiting structures in the dimming motor housing and the lamp housing, and the limiting structures on the two are aligned and then fixed through the fixing screws. During the dimming process, a certain tilt angle is generated on the dimming motor housing, so that the dimming screw is subjected to radial shear force, which affects the life of the dimming shaft. Therefore, the existing installation structure is inconvenient to disassemble and assemble and can easily affect the safety of the dimming motor. Utility Model Content
