Embodiment Construction
[0047] Some typical embodiments embodying the features and advantages of the present invention will be described in detail in the description in the following paragraphs. It should be understood that the present invention can have various changes in different ways without departing from the scope of the present invention, and that the description and illustrations therein are for the purpose of illustration in nature rather than limiting the present invention.
[0048] see figure 1 , which is a partially disassembled schematic diagram of an optical device according to a preferred embodiment of the present invention. Such as figure 1 As shown, an optical device 1, such as a projector, especially an ultra-short-throw projector, includes a lens module 2, a cover structure 3, and an optical adjustment assembly 4 (such as image 3As shown), the cover structure 3 at least partially covers the lens module 2, and the optical adjustment component 4 includes a first adjustment compone...

The invention discloses an optical device and an optical adjusting component thereof. The optical device comprises a lens module, a shell cover structure and an optical adjusting component; the shell cover at least partially covers the lens module; the optical adjusting component comprises a first adjusting component, a second adjusting component and an elastic component; the first adjusting component is arranged on the lens module and comprises a first interference transmission structure; the second adjusting component is movably connected to the shell cover structure and comprises a second interference transmission structure; the elastic component is arranged between the shell cover structure and the second adjusting component and moves along with the movement of the lens so as to elastically push against the second adjusting component to move in a preset distance; therefore, the second interference transmission structure props against the lens module and is stably meshed with the first interference transmission structure so that the second interference transmission structure drives the first interference transmission structure to adjust the optical parameter of the lens module by the first adjusting component.
Description
technical field [0001] The invention relates to an optical device and an optical adjustment component thereof, in particular to an optical device and an optical adjustment component thereof which can reduce costs, save space and facilitate precise adjustment of optical parameters. Background technique [0002] Generally speaking, optical devices, such as projection optical devices such as ultra-short-throw projectors, are equipped with lens modules, and the lens modules can be arranged on the base and covered by the cover structure, but the lens modules are placed on the seat of the optical device. In the body or in the process of handling, use, etc., there may be a slight positional deviation due to the interference of external forces, but even a slight positional deviation may still cause the optical adjustment components to be unable to fit accurately due to uncertainty The position of the lens module is shifted, so that it is difficult to precisely adjust optical paramet...
