Rotary electromagnetic actuator and car lamp low beam and high beam light switching device
A rotary electromagnetic actuator for car lamp low beam and high beam light switching device, comprises a shell (401), a rotor (402), a stator (403), a rotating shaft (405) and an end cover (407). The stator is fixedly installed in the shell to form a pair of arc-shaped stator magnetic poles (409) on which electric excitation can be applied; the rotor, as an arc-shaped permanent magnet, is fixed on the rotating shaft and is located in a magnetic field space of the arc-shaped magnetic poles of the stator; and the rotor is matched with the arc-shaped stator magnetic poles to form a closed magnetic circuit with an air gap (410); two swing bars (406) are connected to two ends of the rotating shaft respectively.
