When each group of optical components is composed of two or more optical elements, the focus adjustment mechanism can be a gear mechanism, and the gear tooth adjustment mechanism converts the rotational motion into the linear motion of the optical elements, by changing the distance between the optical elements Change the focal length of the optical system; when each group of optical components is composed of only one optical element, only the optical element has the feature of adjustable focal length, and the focal length adjustment mechanism can be used to adjust the focal length, such as: liquid lens, focal length adjustment mechanism Apply voltage to the liquid lens or change the shape of the liquid through mechanical force to achieve focal length adjustment. Since the focus adjustment is relatively professional, the focus adjustment mechanism can be designed as gear adjustment, and ordinary users can adjust according to the gear to ensure the display effect.

Embodiment two:

Since the 3D glasses in the embodiment of the utility model will present a large-screen viewing effect (that is, what the human eye sees is a magnified virtual image), it is necessary for the visual optical magnification system to achieve a certain magnification and projection distance, then the object distance of the visual optical magnification system It cannot be too short, so the 3D glasses frame in the first embodiment will be relatively long, making the whole 3D glasses inconvenient to carry and store.

In order to solve the problem that the overall size of the 3D glasses in the first embodiment is too large and inconvenient to carry and store, this second embodiment is based on the first embodiment, and a certain structural design is made on the frame part, so that it can meet the magnification and projection distance, while easy to carry and store.

Referring to Fig. 2, it is a schematic diagram of the structure of the 3D glasses according to the second embodiment of the utility model. Fig. 4 is a schematic diagram of the structure of the frame of the 3D glasses according to the second embodiment of the utility model.
