Title:
CAMERA LENS ADJUSTMENT MECHANISM, PROJECTION MODULE AND PROJECTION DEVICE
Document Type and Number:
Japanese Patent JP2023085191
Kind Code:
A
Abstract:
To provide a camera lens adjustment mechanism, projection module and projection device.SOLUTION: A camera lens adjustment mechanism includes: a support member; a moving member; and a gear. The moving member is located on a lateral side of the support member, and a camera lens is attached to the moving member. The moving member and support member are slidably connected in a first prescribed direction vertical to an optical axis of the camera lens. The moving member includes a rack that extends in a first prescribed direction, and the rack includes a tooth-shaped structure. The gear rotates around an axial direction of an own gear, and the axial direction of the gear is parallel to the optical axis of the camera lens. The teeth of the gear are meshed with the tooth-shaped structure, and a prescribed cross section of an outer circumferential contour of the gear is parallel with the first prescribed direction. The prescribed cross section is located on a side near the rack of the gear, and the prescribed cross section and the optical axis of the camera lens are flush with each other. Compared with a mode that the lens is driven to move through the gear and a lead screw, a transmission speed of the gear and the rack is high, transmission efficiency thereof is also high, thereby, the camera lens can move rapidly.SELECTED DRAWING: Figure 1
