Abstract

The invention provides a projection device and a camera lens module. The projection device comprises an optical mechanical seat and a camera lens module. The optical mechanical seat is provided with a first guide rod and a second guide rod. The first guide rod is substantially parallel to the second guide rod. The camera lens module comprises a main body, at least a first bump and a second bump. The main body is provided with a side surface. The first bump is formed at the side surface and provided with a first through hole. The first bump is slidably disposed at the first guide rod via the first through hole. The second bump is formed at the side surface and provided with a second through hole. The second bump is slidably disposed at the second guide rod via the second through hole. The camera lens module is used for movement relative to the optical mechanical seat along the first guide rod and the second guide rod.

Description

【Technical Field】 [0001] The invention relates to an optical device and its lens module, and more particularly to a projection device and its lens module. 【Background technique】 [0002] The projection device is a display device that can generate images anytime and anywhere. The imaging principle of the projection device is to convert the illumination beam generated by the light source into an image beam through a light valve, and then project the image beam onto the screen or wall through the lens to form an image. With the advancement of projection technology and the reduction of manufacturing costs, the use of projection devices has gradually expanded from commercial use to household use. Recently, all kinds of electronic products are developing towards high-speed, high-efficiency, light, thin, short and small trends, which can have the advantages of being portable and free of space restrictions. [0003] Generally speaking, the lens module of the projection device can be slid...
