Problems solved by technology
In order to achieve the structural stability and precision of the light smart glasses, the light projection engine and the optical element are fixedly installed; that is, the optical element and the light projection engine are mounted to the frame of the glasses, so that when the arms of the glasses are folded relative to the frame of the glasses, the light projection engine is convex. Due to the side of the glasses frame, the thickness of the glasses frame is relatively large, and the glasses legs cannot fit the glasses frame tightly, making it difficult to store

Embodiment Construction
[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
[0043] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiment of the present application, the directional indications are only used to explain the position in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0044] In addition, if there are descriptions involving "first", "second", et...

The invention discloses a projection mechanism and glasses. The projection mechanism comprises an arc-shaped guide rail, a mounting bracket and a projection assembly. The mounting bracket is slidably arranged on the arc-shaped guide rail, and the mounting bracket is provided with a through hole; the projection assembly is arranged in the through hole in a penetrating manner; the arc-shaped guide rail and the mounting bracket are used for connecting a glasses frame and glasses legs; the arc-shaped guide rail and the mounting bracket are respectively used for connecting the glasses frame and the glasses legs, and the mounting bracket is provided with a first position and a second position which are positioned on the arc-shaped guide rail; when the mounting bracket is located at the first position of the arc-shaped guide rail, the light source output end of the projection assembly corresponds to the glasses frame; and when the mounting bracket is located at the second position of the arc-shaped guide rail, the projection assembly is far away from the glasses frame. According to the projection mechanism, the structural compactness of the glasses is improved, and the miniaturization of the glasses is realized.
Description
technical field [0001] The present application relates to the field of virtual reality equipment, in particular to a projection mechanism and glasses using the projection mechanism. Background technique [0002] Virtual reality technology is becoming more and more mature, and gradually differentiates into two forms of products: all-in-one and light smart; among them, light smart glasses are consumer-oriented products. The light smart glasses include a light projection engine and an optical element. The light projection engine irradiates the light beam on the optical element, and the optical element realizes imaging. In order to achieve the structural stability and precision of the light smart glasses, the light projection engine and the optical element are fixedly installed; that is, the optical element and the light projection engine are installed to the frame of the glasses, causing the light projection engine to protrude when the glasses legs are folded relative to the fr...
