Patent number: 11803108Abstract: An adjustment mechanism is adapted to fix and adjust an optical element. The adjustment mechanism includes a housing, a fixing member and an elastic member. The housing is adapted for accommodate the optical element, and has a side wall, and the side wall has a locking portion protruding outward. The fixing member is disposed beside the side wall. The fixing member has a joint portion. The elastic member is disposed between the fixing member and the housing. The elastic member has a first end and a second end relative to the first end. The first end is combined with the joint portion, and the second end is abutted against the side wall. The adjusting part passes through the opening and connects with the locking portion. A projection device is further provided. The adjustment mechanism and the projection device of the invention may improve the assembly process and reduce costs.Type: GrantFiled: August 27, 2021Date of Patent: October 31, 2023Assignee: Coretronic CorporationInventor: Chia-Ching Tso

Patent number: 10871705Abstract: The invention provides a projection device, comprising an illumination system, a light valve, a light guide element, an optical module and a projection lens. The optical module comprises a fixed portion, a first frame body, at least one first driving element and an optical element. The first frame body is pivoted to the fixed portion and comprises a first side and other three second sides. The first driving element is configured on at least one of the other three second sides and configured to drive the first frame body to oscillate back and forth. A first virtual plane of the projection lens intersects with a second virtual plane of the light valve to form a virtual line segment. The distance between the first side and the virtual line segment is shorter than the distance between the other three second sides and the virtual line segment.Type: GrantFiled: May 22, 2020Date of Patent: December 22, 2020Assignee: Coretronic CorporationInventors: Wei-Hao Chen, Shu-Yu Lin, Chia-Ching Tso
