[0075] The adjustable focal length AR glasses lens structure of an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0076] Please see Figures 1-6 In this embodiment, the lens assembly includes: a frame assembly 1; a lens assembly 2, which is slidably disposed at the end of the frame assembly 1 and can move toward or away from the frame assembly 1 to accommodate zooming; and a drive assembly 3, which is disposed within the frame assembly 1 and can rotate within the frame assembly 1 or move along the length of the frame assembly 1. The drive assembly 3 is connected to the lens assembly 2 to facilitate movement of the lens assembly 2. When it is necessary to move the lens assembly 2 for zooming, the drive assembly 3 can be rotated to enable the drive assembly 3 to drive the lens assembly 2 to move, thereby achieving zooming.

[0077] By designing a sliding structure for the lens assembly 2 on the frame assembly 1, users can easily adjust the focal length of the lenses according to their actual needs, thus obtaining a clear and comfortable visual experience at different distances. This design avoids the visual fatigue and discomfort caused by the fixed focal length of traditional AR glasses, greatly improving user comfort and satisfaction.

[0078] The driving component 3 can drive the lens component 2 to move toward or away from the frame component 1, realizing the zoom function; this allows the AR glasses to adapt more flexibly to different application scenarios, such as education, entertainment, medical, and industrial applications, providing users with a richer and more diverse AR experience;

[0079] Compared to traditional zoom methods, this invention uses the rotation or movement of the drive component 3 to move the lens component 2, achieving rapid and accurate focal length adjustment. Users can easily adjust the focal length without complicated operations or long waiting times, improving efficiency and convenience.

[0080] In this embodiment, the frame assembly 1 includes: a first support leg 101, which has a first cavity inside and is arranged along the length direction of the first support leg 101; a second support leg 102, which has a second cavity inside the first support leg 101 and is arranged along the length direction of the second support leg 102; and a connecting rod 103, which is located between the first support leg 101 and the second support leg 102, with both ends of the connecting rod 103 connected to the first support leg 101 and the second support leg 102 respectively; the connecting rod 103 connects the first support leg 101 and the second support leg 102 so that the first support leg 101 and the second support leg 102 can be worn on the ears on both sides of the user's head.

[0081] In this embodiment, the frame assembly 1 further includes: a first support rod 104, which is disposed at one end of the bottom of the connecting rod 103 and is inclined; a first fixing plate 105, which is disposed at the bottom of the first support rod 104; a first fixing groove 106, which is disposed on the first fixing plate 105 and is circular; a plurality of first limiting grooves 107, which are equally spaced around the inner circumferential surface of the first fixing groove 106; a first turntable 108, which is rotatably disposed within the first fixing groove 106; a plurality of first springs, which are equally spaced on the outer circumferential surface of the first turntable 108; a plurality of first positioning beads 110, which are connected to the plurality of first springs and correspond to the plurality of first limiting grooves 107; and a first connecting... A first connecting plate 111 is disposed on a first turntable 108; a first nose pad 112 is disposed on the side of the first connecting plate 111. Before wearing, the user can rotate the first nose pad 112 according to their nose shape. When the first nose pad 112 rotates, it drives the first turntable 108 to rotate in the first fixing groove 106. Multiple first springs and multiple first positioning beads 110 also rotate in the first fixing groove 106. When the multiple first positioning beads 110 rotate, they abut against the inner circumferential surface of the first fixing groove 106 and compress the multiple first springs respectively. When the multiple first positioning beads 110 rotate to correspond to the multiple first limiting grooves 107, the multiple first springs push the multiple first positioning beads 110 into the corresponding first limiting grooves 107 respectively through the elastic potential energy after compression. This prevents the first nose pad 112 from shaking or rotating during use.

[0082] In this embodiment, the frame assembly 1 includes: a second support rod 113, which is located at the other end of the bottom of the connecting rod 103 and is inclined; a second fixing plate 114, which is located at the bottom of the second support rod 113; a second fixing groove 115, which is located on the second fixing plate 114 and is circular; a plurality of second limiting grooves 116, which are equally spaced around the inner circumferential surface of the second fixing groove 115; a second turntable 117, which is rotatably disposed within the second fixing groove 115; a plurality of second springs, which are equally spaced on the outer circumferential surface of the second turntable 117; a plurality of second positioning beads 119, which are connected to a plurality of first springs and correspond to a plurality of second limiting grooves 116; and a second connecting rod 103. A connecting plate 120 is mounted on a second turntable 117; a second nose pad 121 is mounted on the side of the connecting plate 120. Before wearing, the user can rotate the second nose pad 121 according to their nose shape. When the second nose pad 121 rotates, it drives the second turntable 117 to rotate within the second fixing groove 115. Multiple second springs and multiple second positioning beads 119 also rotate within the second fixing groove 115. When the multiple second positioning beads 119 rotate, they abut against the inner circumferential surface of the second fixing groove 115 and compress the multiple second springs. When the multiple second positioning beads 119 rotate to correspond to the multiple second limiting grooves 116, the multiple second springs use their compressed elastic potential energy to push the multiple second positioning beads 119 into the corresponding second limiting grooves 116, so that the second nose pad 121 will not shake or rotate during use.

[0083] In this embodiment, the lens assembly 2 includes: a first slide groove 201, which is disposed at the top of the first cavity, extends along the length of the first cavity, and passes through the end of the first support leg 101; a first slide rod 202, which is slidably disposed within the first slide groove 201, and extends to the outside of the first support leg 101; a second slide groove 203, which is disposed at the top of the second cavity, extends along the length of the second cavity, and passes through to the end of the second support leg 102; and a second slide rod 204. 4.

[0084] In this embodiment, the drive assembly 3 includes: two first bearings disposed on both sides of the first end of the first cavity; a first rotating shaft 302 rotatably disposed within the two first bearings and extending to the end of the first support leg 101; a first gear 303 sleeved on the first rotating shaft 302; and a knob 304 disposed at the end of the first rotating shaft 302. The drive assembly 3 further includes: two second bearings disposed on both sides of the second end of the first cavity; a second rotating shaft 306 rotatably disposed within the two second bearings; a second gear 307 sleeved on the second rotating shaft 306; and a belt 308 meshing with the first gear 303 and the second gear 307. The connecting block 309 is connected at one end to the belt 308 and at the other end to the first slide rod 202. When it is necessary to move the lens closer to or away from the frame assembly 1, the knob 304 can be rotated clockwise or counterclockwise. The knob 304 drives the first rotating shaft 302 to rotate. When the first rotating shaft 302 rotates, it drives the first gear 303 to rotate. The first gear 303 meshes with the belt 308, so that the belt 308 rotates on the first gear 303 and the second gear 307. When the belt 308 rotates, the connecting block 309 drives the first slide rod 202 to rotate in the first slide groove 201, so that the first slide rod 202 can push the lens to move closer to or away from the frame assembly 1, thereby achieving zoom.
