  • Light path adjustment mechanism
    Patent number: 11774745
    Abstract: A light path adjustment mechanism includes a support, a carrier, an optical plate member, a permanent magnet and an electromagnet. The carrier is disposed in the support and connected to the support by a first elastic member and a second elastic member, the first elastic member and the second elastic member are configured to twist substantially about a first axial direction, and the optical plate member is disposed on the carrier. An attractive force or a repulsive force generated between the permanent magnet and the electromagnet acts in a direction substantially perpendicular to the first axial direction, and one end of the carrier is provided with the permanent magnet or the electromagnet.
    Type: Grant
