AR glasses

1 . AR (augmented reality) glasses, comprising:

a frame having a frame opening for mounting lens, wherein the frame comprises multiple layers of shell structures stacked along a thickness direction of the frame, the multiple layers of shell structures are enclosed together to form a mounting cavity disposed along a circumferential direction of the frame opening, the mounting cavity comprises a first side wall constituting a side wall of the frame opening, a second side wall away from the frame opening, and an inner end wall and an outer end wall disposed in sequence in the thickness direction of the frame, the first side wall, the second side wall, the inner end wall and the outer end wall are disposed on the multiple layers of shell structures separately, and at most two of the first side wall, the second side wall, the inner end wall and the outer end wall are disposed on any one layer of shell structure;

two glasses legs movably connected to both ends of the frame respectively; and

at least one electronic device disposed in the mounting cavity,

wherein the multiple layers of shell structures comprise an inner shell, a frame bracket and an outer shell, and the inner shell, the frame bracket and the outer shell define a mounting cavity, and

wherein the first side wall and the second side wall are separately disposed on the inner shell and the frame bracket, the inner end wall is disposed on the frame bracket, and the outer end wall is disposed on the outer shell.

2 . The AR glasses of claim 1 , wherein the first side wall is disposed on the inner shell, and the second side wall and the inner end wall are disposed on the frame bracket.

3 . The AR glasses of claim 2 , wherein the frame bracket comprises:

a bracket body provided with a central opening, wherein a part of an outer portion of the bracket body surrounding the central opening forms the inner end wall; and

a central protrusion disposed on an outer side of the bracket body and disposed around a periphery of the central opening to form the second side wall,

wherein the inner shell comprises:

an inner shell body provided with an inner opening; and

an inner protrusion provided outside of the inner shell body and disposed along an edge of the inner opening, wherein the inner protrusion passes through the central opening to form the first side wall, and

wherein the outer shell is provided with an outer opening, the outer opening is connected with the central opening and the inner opening to form the frame opening, and a portion of the outer shell surrounding the outer opening constitutes the outer end wall.

4 . The AR glasses of claim 1 , wherein the inner shell, the frame bracket and the outer shell are bonded by adhesive.

5 . The AR glasses of claim 1 , wherein the electronic device is disposed on the frame bracket.

6 . The AR glasses of claim 1 , wherein the electronic device comprises FPC (flexible printed circuit).

7 . The AR glasses of claim 1 , wherein each of the glasses legs comprises an inner leg shell, a leg shell bracket and an outer leg shell disposed along a thickness direction of the glasses legs.

8 . The AR glasses of claim 7 , wherein the electronic devices are provided in plural, and one electronic device is provided on the leg shell bracket.

9 . The AR glasses of claim 7 , wherein the leg shell bracket is rotatably connected to the frame bracket.
