When the first connecting portion 3 rotates relative to the rotating shaft member 1, during the process that the boss 211 slides out of the groove 31 along the guiding inclined plane 33, the guiding inclined plane 33 presses against the boss 211, so that the damping ring 21 compresses the elastic member 22 to deform, so that the damping ring 21 is displaced along the axial direction of the rotating shaft member 1, and thus the elastic action of the elastic member 22 can be utilized to provide a reaction force for the damping ring 21, so that the damping force between the damping ring 21 and the first connecting portion 3 is ensured. When the boss 211 completely slides out of the groove 31 along the guiding inclined plane 33, the damping ring 21 compresses the elastic member 22 to deform to the greatest extent, and the elastic action of the elastic member 22 provides the damping ring 21 with the greatest reaction force to increase the damping force between the damping ring 21 and the first connecting portion 3, so that the first connecting portion 3 is static relative to the rotating shaft member 1 under the action of the damping force, and the first connecting portion 3 rotates relative to the rotating shaft member 1 only under the action of the larger rotating force, so that different rotating angles of the first connecting portion 3 and the second connecting portion 4 can be adjusted, so that the AR glasses 800 are suitable for different users to wear, and wearing comfort and universality are improved.

In an embodiment, as shown in fig. 2 to 4, the hinge structure 100 further includes a spacer 5, where the spacer 5 is sleeved on the rotating shaft 11 and located between the first connecting portion 3 and the second connecting portion 4 or the fixing member 12. It will be appreciated that by providing the spacer 5, wear between the first connection part 3 and the second connection part 4 or the securing member 12 is avoided by the spacer 5.

Optionally, the pad 5 is a wear-resistant pad, for example made of elastic or flexible material such as rubber. In the present embodiment, the first connecting portion 3 and the second connecting portion 4 may be injection molded using a plastic material, or may be formed using a metal material, and the present invention is not limited thereto.

The hinge structure 100 of the present invention operates on the principle that: when the first connecting part 3 and the second connecting part 4 rotate respectively and the second connecting part 4 drives the rotating shaft piece 1 to rotate, the boss 211 of the damping ring 21 on the rotating shaft piece 1 rotates along with the rotation, so that the relative rotation with the groove 31 of the first connecting part 3 is realized; the side wall of the groove 31 of the first connecting part 3 is provided with a guiding inclined plane 33, the boss 211 is provided with an inclined plane 215, and the relative movement of the first connecting part 3 and the damping ring 21 in the Z direction (the axial direction of the rotating shaft 11) is realized through the relative rotation of the guiding inclined plane 33 and the inclined plane 215. Since the upper portion of the first connecting portion 3 has no compressible structure, the lower damping ring 21 is pushed to move downward by the guiding inclined surface 33, so that the elastic member 22 of the elastic assembly 2 is compressed, and the elastic member 22 generates a reaction force in the Z direction.

It can be understood that the first connecting portion 3 and the second connecting portion 4 rotate relatively, and the rotation of the second connecting portion 4 drives the rotation shaft member 1 and the boss 211 to rotate synchronously; along with the relative rotation, the groove 31 of the first connecting portion 3 and the boss 211 relatively rotate, when the inclined surface 215 of the damping ring 21 slides along the guiding inclined surface 33, the Z-direction movement is performed, the inclined surface 215 is separated from the guiding inclined surface 33, so that the boss 211 is separated from the groove 31, the damping ring 21 is pressed downwards to press the elastic piece 22 of the lower elastic assembly 2, and the elastic piece 22 generates a Z-direction reaction force, so that the damping ring 21 generates elastic damping handfeel.

It should be noted that, along with the relative rotation, the groove 31 of the first connecting portion 3 and the boss 211 rotate relatively, the inclined surface 215 of the damping ring 21 slides along the guiding inclined surface 33, and when the inclined surface 215 does not separate from the guiding inclined surface 33, the force applied by the relative rotation of the first connecting portion 3 and the second connecting portion 4 is cancelled, and the elastic member 22 pushes the damping ring 21 to automatically reset along the rotation shaft 11, so as to restore the clamping force.

It can be understood that after the recess 31 and the protrusion 211 are completely separated, the elastic member 22 of the elastic assembly 2 is compressed due to no Z-direction relative displacement, and the first connecting portion 3 and the damping ring 21 are pressed by the elastic member 22 of the elastic assembly 2 to generate friction force, so that the first connecting portion 3 can hover at multiple angles relative to the rotating shaft 11. By adjusting the matching angle of the first connecting part 3 and the boss 211 and the elasticity of the elastic piece 22, different automatic opening and closing angles and different damping handfeel are adjusted. Meanwhile, the design of the wear-resistant gasket 5 can reduce friction between the second connecting part 4 above and the fixing nut or between the first connecting part 3 and the second connecting part 4, and the service life of the hinge structure 100 is prolonged.
