Embodiment

[0078] An embodiment of the optical type conversion driving device is shown in the figure. In the embodiment of the optical type conversion driving device shown in the accompanying drawings, it includes a housing 401, a rotating shaft subassembly 402, a stator core 403, a rotating shaft 405 and an end cover 407, used to drive the movable sunshield 2 of the vehicle light type conversion device. In order to more clearly show the internal structure of the optical type conversion driving device 4, image 3 with Figure 4 The end cap 407 is omitted.

[0079] The stator core 403 is provided with a stator winding 404 , and the stator core 403 and the stator winding 404 are fixedly installed inside the housing 401 to form a pair of arc-shaped stator poles that can be energized and excited.

[0080] The rotating shaft subassembly 402 is an arc-shaped magnetic steel part, which is fixed on the rotating shaft 405 and placed in the magnetic field space of the arc-shaped magnetic pole of...

Abstract

The invention provides a light form conversion drive device rotary shaft sub assembly used for driving a light shading board of a vehicle lamp light form conversion device to swing. The rotary shaft sub assembly is provided with arc-shaped magnetic steel arranged in a magnetic field space of an arc-shaped stator magnetic pole. The rotary shaft sub assembly is matched with the arc-shaped stator magnetic pole, so that a closed magnetic circuit with a gap is formed. The rotary shaft sub assembly is a rotor with a sector section and comprises a sector body fixedly connected with a rotary shaft, and arc-shaped crown magnetic steel (a permanent magnet) arranged on the arc-shaped outer circumferential face of the sector body. The rotary shaft sub assembly swings around the rotary shaft at the original point, each of the two ends of the rotary shaft sub assembly is connected with a swing rod extending in the radial direction of the rotary shaft, the swing rods are used for driving the light shading board to swing, and the swing angle of the light shading board is the same as the rotation angle of the rotary shaft sub assembly. By the adoption of the light form conversion drive device rotary shaft sub assembly, the motion form of a light form conversion drive device is changed, so that the technical problem that a light form conversion mechanism is high in noise in work is solved, meanwhile, light form shaking is avoided, and the reliability of the light form conversion mechanism is improved.

Description

technical field [0001] The present invention relates to a rotary electromagnetic actuator for vehicle lamps. Specifically, the present invention relates to a shaft sub-assembly of a light type conversion driving device used for a vehicle light type conversion device and an application method thereof. The light type conversion drive The sub-assembly of the rotating shaft of the device and its application are used to drive the swing of the visor of the light type changing device, so as to realize the light type change, reduce the collision noise when the electromagnet is engaged and released, and provide users with a more comfortable driving environment . 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 st...
