Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional display equipment, and in particular to an adjustable three-dimensional display device. Background Art

[0002] 3D display devices can provide a more realistic visual experience. In terms of film and television entertainment, viewers can feel that the scenes in movies, TV series, games, etc. are presented as if they are real, which enhances the sense of immersion. The audience can more clearly feel the distance, size and spatial position of objects, as if they are in the scene, and have a more direct interactive experience with the characters and scenes.

[0003] When using existing three-dimensional display devices, the display angle needs to be frequently readjusted, the friction of the connecting components is reduced, and the display structure is prone to shaking, affecting the user's viewing experience. In addition, the lens array must ensure good light guidance and is generally disassembled regularly for maintenance and cleaning. However, the installation and disassembly process of the lens array is relatively cumbersome, which greatly reduces the operation and maintenance efficiency. Moreover, during the angle adjustment process, the lens array is easily subjected to uneven forces, causing slight displacements. Position offset may cause the optical path to be incorrect, affecting the normal operation of the device. Summary of the invention

The mounting frame can be rotated by manually rotating a first knob to cause the lens array plate and the self-luminous panel to deflect around a rotating rod. When the angle adjustment is completed, the elastic action of the compression spring is utilized to slide the first knob to the right along the spline shaft, and the first knob is quickly limited by the engagement of the ratchet sleeve and the ratchet groove, thereby effectively maintaining the set angle of the lens array plate and the self-luminous panel, avoiding up and down swinging, and ensuring the viewing experience of the user.
