Foldable glasses leg assembly and head-mounted equipment

Abstract

The invention discloses a foldable glasses leg assembly and head-mounted equipment. A rotating shaft assembly comprises a glasses frame connecting part, a glasses leg connecting part and a cam assembly; the glasses frame connecting part and the glasses leg connecting part are respectively provided with connecting shafts; and a second cam in the cam assembly matches a first cam and arranged on oneconnecting shaft in a sleeving mode, and the first cam moves in an axial direction. When the first cam and the second cam are mutually embedded, the glasses frame and the glasses legs can be fixed atspecific positions; and when the first cam and the second cam push each other, an elastic part applies an acting force for clinging the first cam to the second cam. And the head-mounted equipment cankeep a certain clamping force when the glasses legs are bent reversely, so that the wearing comfort is improved. And when the glasses legs are folded, an FPC assembly is not exposed, so that the product reliability is improved.

Description

technical field [0001] The invention relates to the technical field of head-mounted devices, in particular to a foldable temple assembly and a head-mounted device. Background technique [0002] Smart devices such as AR / VR / MR have been favored by a wide range of consumers in recent years, and various head-mounted and glasses-type products continue to emerge. Taking AR glasses as an example, AR glasses can bring users a rich visual experience, and are worn on the user's head in the form of glasses, which is convenient for users to use. The existing AR glasses on the market are still not well adapted to wear on various head shapes and guarantee a certain clamping force, and the user experience is not very comfortable to wear. [0003] In addition, due to the small internal space of AR glasses, the usable space can be said to be arranged with relevant hardware, and FPC and other lines are spread throughout the entire product. When AR glasses are folded, FPC and other lines are ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problems pointed out in the background technology that AR glasses are uncomfortable to wear and the lines are exposed when folded, the present invention proposes a foldable temple assembly and a head-mounted device, which have a better stop feeling when the mirror legs are folded through a concave-convex wheel mechanism , and can maintain a certain clamping force when the temples are folded, so as to adapt to different head shapes and improve wearing comfort; the concave-convex mechanism includes a gear structure, and the synchronization of the frame and the temples is realized through the gear structure Move in opposite directions, so that the actual folding angle of the mirror legs is smaller than the changing angle between the mirror legs and the frame, so as to reduce the bending deformation of the internal circuit, and at the same time, the circuit is not exposed when the mirror legs are folded, which improves product reliability
