Abstract

The invention discloses a rotary electromagnetic actuating mechanism and a car lamp upper and lower beam switching device thereof, and relates to an illuminating device or functional characteristics or parts of a system of the illuminating device. The rotary electromagnetic actuating mechanism comprises a shell, a rotor, a stator, a rotary shaft and an end cover; stator windings are arranged on the stator, and the stator and the stator windings are fixedly mounted in the shell to form a pair of arc-shaped stator magnetic poles capable of being electrified to be excited; the rotor is an arc-shaped permanent magnet, is fixed onto the rotary shaft, is placed in magnetic field space of the arc-shaped stator magnetic poles and is matched with the arc-shaped stator magnetic poles, so that a closed magnetic circuit with air gaps is formed; and two ends of the rotary shaft are respectively connected with two oscillating bars radially extending along the rotary shaft. A shading plate of the car lamp upper and lower beam switching device is fixedly connected onto the oscillating bars at the two ends of the rotary shaft, an oscillating angle of the shading plate is identical to a rotation angle of the rotor, the rotary electromagnetic actuating mechanism drives the shading plate to realize switching between upper beams and lower beams, collision noise generated when electromagnets are sucked and released is avoided, and a comfortable driving environment is provided for users.

Description

technical field [0001] The present invention relates to a lighting device or the functional features or parts of its system, in particular to a rotary electromagnetic actuator that changes the characteristics and distribution of light emission by means of adjusting parts, and a high and low beam switching device for a car lamp. Background technique [0002] When the driver is driving, it is inevitable that there will be car meeting and uphill and downhill situations. Especially when the car is driving at night, the lights of the opposite cars and the reflected light of the road when going up and down will affect the driver's vision. If it is too strong, the driver will not be able to see the road ahead, so the driver needs to switch in time. If the far and near beams of the car are not switched in time, it may cause traffic accidents. Therefore, modern vehicles widely use far and near beam switching mechanisms to realize the far and near beam switching control of automobile...
