Problems solved by technology

However, it is difficult for this device to adjust the inclination angle of the headlight in time
At the same time, since the position of the circuit for collecting light signals cannot be completely consistent with the driver's viewing angle, it will bring visual deviation to the driver.
What's more, the circuit will misjudge other lighting lights around the vehicle as the lights of other vehicles and cause the lighting system to malfunction, thereby causing danger.
In addition, the device has a complex structure and is inconvenient to use

Embodiment

[0047] The rotary actuator device of the automobile headlight dimming system of the present invention has: a motor 1, a casing 2, a metal thread transmission rod 3, and a slide block (4.

[0048] The structure of the rotary actuator device is that the metal threaded transmission rod 3 is driven to reciprocate linearly by the rotation of the motor, thereby driving the slider 4 to reciprocate linearly along the guide rail 2c in the housing 2 connected to the motor. The slider 4 is connected to the optical unit 6 through the cooperation of the barb 4a and the lever 5, and drives the optical unit 6 to rotate.

[0049] The motor 1 is fixed by the motor casing 1a and the motor cover 1b, and its input leads are fixed through the tooth row 1b on the motor casing 1a.

[0050] Described casing 2 is to be connected with motor casing 1a, and casing 2 inside has guide rail 2c, and casing 2 and the bottom surface that PCB board (circuit board) cooperates have three positioning pins 2b and a...

Abstract

The invention provides a rotary actuator of a dimming system of a car headlight, and the rotary actuator can convert rectilinear motion into rotary motion, so that the light directions of the car headlight can be regulated. The rotary actuator comprises a motor (1), a housing (2), a metallic threaded drive rod (3) and a sliding block (4). The rotation of the motor drives the metallic threaded drive rod to move forwards and backwards in a straight line. A sliding block is arranged at the end part of the metallic threaded drive rod, the sliding block is connected with an optical unit (6), the rectilinear motion of the sliding block is converted into the rotary motion of the optical unit, so that the optical unit can rotate within the certain angle, thereby regulating the light direction of the car headlight.

Description

technical field [0001] The invention relates to a lamp device for vehicles, in particular, the invention relates to a rotary actuator used for a dimming system of a headlamp of an automobile. The rotary actuator of the automotive headlamp dimming system can convert the rotary motion into linear motion, and then convert the linear motion into rotary motion, thereby realizing the adjustment of the irradiation direction of the automotive headlamp. Background technique [0002] When driving at night, only by installing good headlights and adjusting the inclination angle of the headlights anytime and anywhere can you drive well and ensure driving safety. [0003] However, when driving at night, when two vehicles meet, road conditions change, vehicle conditions change, brake and speed up, etc., it is often difficult for the headlights of the traditional vehicle lighting system to provide timely and sufficient lighting to ensure driving safety. [0004] First of all, changes in th...
