Abstract

The present disclosure relates to the field of augmented reality technology, and in particular to augmented reality glasses. The augmented reality glasses include: a headgear assembly configured to secure the augmented reality glasses on a user's head; an optomechanical assembly; a frame assembly configured to carry the optomechanical assembly; and a damping rotary structure configured to rotatably connect the headgear assembly and the frame assembly such that when the augmented reality glasses are worn on a user's head, the user is allowed to see a picture displayed by the optomechanical assembly.

First claim

The invention claimed is:

1. Augmented reality glasses, comprising:
a headgear assembly configured to secure the augmented reality glasses to a head of a user;
an optomechanical assembly comprising a display;
a frame assembly configured to carry the optomechanical assembly;
a damping rotary structure configured to rotatably connect the headgear assembly and the frame assembly, such that when the augmented reality glasses are worn on the head of the user, the user views a picture displayed by the display of the optomechanical assembly; and
a rotation transmission member configured to synchronize a rotation of the frame assembly with a rotation of the display, such that when the augmented reality glasses are worn on the head of the user, the picture displayed by the display enters eyes of the user substantially vertically,
wherein the rotation transmission member is inside the frame assembly and comprises:
a first transmission component adjacent the damping rotary structure and engaged with the frame assembly;
a second transmission component adjacent and engaged with the optomechanical assembly; and
a third transmission component between the first transmission component and the second transmission component.

2. The augmented reality glasses according to claim 1 ,
wherein the frame assembly is U-shaped, and
wherein the damping rotary structure comprises two sub-damping rotary structures at a first end and a second end of the U-shaped frame assembly respectively.

3. The augmented reality glasses according to claim 2 ,
wherein the frame assembly further comprises a recess at a position opposite to an open portion of the frame assembly,
wherein the recess penetrates through the frame assembly in a thickness direction thereof, and
wherein the optomechanical assembly is in the recess.

4. The augmented reality glasses according to claim 1 ,
wherein the headgear assembly has an annular shape, and
wherein the headgear assembly comprises a knob for adjusting a size of the headgear assembly.

5. The augmented reality glasses according to claim 1 , wherein the optomechanical assembly comprises:
an input interface configured to receive a signal; and
optics configured to direct the signal into the display for displaying,
wherein the display is configured to display the picture toward eyes of the user when the augmented reality glasses are worn on the head of the user.

6. The augmented reality glasses according to claim 5 , wherein the optomechanical assembly further comprises:
an imaging element configured to record a scene in front of the user.

7. The augmented reality glasses according to claim 5 ,
wherein the display is configured to rotate in a reverse direction with respect to a rotation of the frame assembly.

8. The augmented reality glasses according to claim 7 , wherein the first transmission component comprises:
a first rotating shaft connection gear;
a first rotating member; and
a first rotating shaft joint connecting the first rotating shaft connection gear and the first rotating member,
wherein the first rotating shaft connection gear engages with a transmission gear on an outer casing of the frame assembly.

9. The augmented reality glasses according to claim 7 , wherein the second transmission component comprises:
a limit block,
wherein a first end of the limit block is provided with a second gear that is configured to engage with the third transmission component, and
wherein limit slots are inside the limit block, and
wherein the limit slots are configured to engage with a limit hole in the optomechanical assembly, such that the display rotates in a reverse direction with respect to the rotation of the frame assembly.

10. The augmented reality glasses according to claim 9 , wherein the limit slots inside the limit block are further configured to decouple from the limit hole in the optomechanical assembly.

11. The augmented reality glasses according to claim 7 , wherein the third transmission component comprises:
a third rotating shaft connection gear configured to engage with the second transmission component;
a third rotating member; and
a pair of third rotating shaft joints,
wherein a first one of the pair of third rotating shaft joints is configured to connect the third rotating shaft connection gear and the third rotating member, and a second one of the pair of third rotating shaft joints is configured to connect the third rotating member and the first transmission component.

12. The augmented reality glasses according to claim 11 , wherein the third transmission component further comprises:
a plurality of additional third rotating members and a plurality of additional third rotating shaft joints, connected to a first end or a second end of a corresponding additional third rotating member.

13. The augmented reality glasses according to claim 12 ,
wherein any one of the third rotating member, the third rotating shaft joint, the plurality of additional third rotating members and the plurality of additional third rotating shaft joints is made of a rigid material.

14. The augmented reality glasses according to claim 12 ,
wherein any one of the third rotating member, the third rotating shaft joint, the plurality of additional third rotating members and the plurality of additional third rotating shaft joints is made of a rigid material.

15. The augmented reality glasses according to claim 1 , wherein the frame assembly comprises:
an inner casing fitting the head of the user; and
an outer casing that is exposed outside when the augmented reality glasses are worn on the head of the user,
wherein the outer casing of the frame assembly is provided with a stud,
wherein the damping rotary structure comprises a screw, an elastic spacer and a damping element,
wherein the screw passes through the headgear assembly and the elastic spacer and engages with the damping element, and
wherein the damping element passes through the inner casing of the frame assembly and engages with the stud.
