Title:
LIGHT-TYPE CONVERSION DRIVING DEVICE FOR CAR LAMP LIGHT-TYPE CONVERSION DEVICE AND CONVERSION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/147956
Kind Code:
A1
Abstract:
Provided is a light-type conversion driving device for a car lamp light-type conversion device, comprising a shell (401), a rotating shaft subassembly (402), a stator (403), a rotating shaft (405) and an end cover (407). The stator (403) and a stator winding (404) inside the shell (401) constitute a pair of arc-shaped stator magnetic poles capable of being electrically excited. The rotating shaft subassembly (402) is an arc-shaped permanent magnet, is fixed on the rotating shaft (405), and is arranged in a magnetic field space of the arc-shaped magnetic poles of the stator (403). The rotating shaft subassembly (402) is matched with the arc-shaped stator magnetic pole to form a closed magnetic circuit with an air gap. Two ends of the rotating shaft (405) are respectively connected with an oscillating bar which extends in the radial direction of the rotating shaft. A movable shading plate (2) is fixedly connected to the oscillating bar on the two ends of the rotating shaft (405), and the oscillating angle of the shading plate is the same as the rotation angle of the rotating shaft subassembly (402). Further provided is a conversion method using the light-type conversion driving device. A mode whereby a rotation-type electromagnetic execution mechanism is used for driving the shading plate is adopted to achieve light-type conversion, collision noise generated in the electromagnet attracting and releasing processes is reduced, and a more comfortable driving environment is provided for a user.
