[0044] The technical solutions in the embodiments (or, the implementation manners) of the present application will be described clearly and completely with reference to the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0045] If the embodiments of the present application involve directional indications or positional relationships (for example, up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such directional indications or positional relationships are only used to explain the relative positional relationships, movement conditions, etc. between components in a certain posture (as shown in the drawings); if the certain posture changes, the directional indications or positional relationships also change accordingly. In addition, the terms “first”, “second”, etc. in the embodiments of the present application are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0046] The interpupillary distance adjusting structure, the frame and the smart glass according to the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The features in the following embodiments and implementation manners can be complementary or combined with each other without conflict.

[0047] The embodiment of the present application provides a pupil distance adjusting structure, which can be used in a frame. Specifically, the pupil distance adjusting structure can be used in the shell 40 of the frame as shown in FIG. 1 to FIG. 3.

[0048] As shown in FIG. 3, the pupil distance adjusting structure comprises a mounting part and an adjusting part 20. The mounting part and the adjusting part 20 can be arranged on the shell 40. The mounting part comprises two mounting structures 11. Each mounting structure 11 comprises a first guide 110 for guiding the movement of the lens barrel 200 mounted on the mounting structure 11 along the length direction of the first guide 110, and the length directions of the two first guides 110 are parallel or on the same line.

[0049] The adjusting part 20 comprises a rotating structure 21 and a connecting piece 22, the connecting piece 22 is used for connecting at least one lens barrel 200 mounted on the mounting structure 11 and the rotating structure 21. When the rotating structure 21 rotates, the lens barrel 200 connected with the connecting piece 22 is driven to move along the first guide 110 through the connecting piece 22.

[0050] The pupil distance adjusting structure provided by the embodiment of the present application can drive the lens barrel 200 connected with the connecting piece 22 to move along the first guide 110 through the connecting piece 22 when the rotating structure 21 rotates, so that the distance between the two lens barrels 200 is reduced or increased, and then the distance between the optical centers of the two lens barrels 200 is equal to the pupil distance of the user, which brings the user the best visual experience and improves the wearing comfort of the user. When the user needs to adjust the distance between the lens barrels 200, the user only needs to rotate the rotating structure 21, and the user can adjust the position of the lens barrel 200 at any time according to the visual feeling of the user during the wearing process, which is simple and fast. By arranging the length directions of the two first guides 110 on the same line or parallel, the optical centers of the two lens barrels 200 remain on the same line after the adjusting part 20 drives the lens barrel 200 to move along the length direction of the first guide 110, which does not affect the visual experience of the user.

[0051] In one embodiment, as shown in FIG. 3, the pupil distance adjusting structure comprises two adjusting parts 20, each adjusting part 20 corresponds to one mounting structure 11, the connecting piece 22 is used for connecting the lens barrel 200 mounted on the mounting structure 11 and the rotating structure 21 corresponding to the mounting structure 11. In this way, each lens barrel 200 can be independently adjusted by the adjusting part 20 corresponding to the lens barrel 200, for example, the position of one lens barrel 200 can be adjusted without moving the other lens barrel 200, and the user can flexibly adjust the position of each lens barrel 200 according to the needs of the user to obtain the best wearing experience.

[0052] In one embodiment, as shown in FIGS. 5 and 6, the first guide 110 is in the shape of a rod, and the mounting portion is further provided with four clamping grooves 1101, and each end of the first guide 110 is clamped in a clamping groove 1101. The clamping grooves 1101 can be provided on the outer shell 40. As shown in FIGS. 7 to 9, each lens barrel 200 is provided with a first sliding block 201, and each first sliding block 201 is provided with a through hole 2011 through which the first guide 110 passes. When the connecting member 22 drives the lens barrel 200 to move, the first sliding block 201 moves along the length direction of the first guide 110. In the embodiment shown in FIG. 8, each lens barrel 200 is provided with two first sliding blocks 201. In other embodiments, each lens barrel 200 can be provided with one first sliding block 201, or three or more first sliding blocks 201.

[0053] In one embodiment, as shown in FIGS. 3 and 5, the mounting portion is further provided with four second limiting structures 112, and each end of the first guide 110 is provided with a second limiting structure 112, and the second limiting structure 112 is used for limiting the lens barrel 200. The second limiting structure 112 can define the limit position of the movement of the lens barrel 200, so as to avoid that the distance of the movement of the lens barrel 200 is too large and the lens barrel 200 is separated from the first guide 110, thereby reducing the risk of damage of the lens barrel 200.

[0054] In the embodiments shown in FIGS. 3 and 6, each second limiting structure 112 covers a clamping groove 1101. In this way, the first guide 110 is limited between the second limiting structure 112 and the clamping groove 1101, so as to prevent the first guide 110 from falling off.

[0055] In one embodiment, as shown in FIGS. 2 and 3, each mounting structure 11 further comprises a second guide 111, the second guide 111 is used for mounting the lens barrel 200 and guiding the movement of the lens barrel 200 along the length direction thereof, and the length direction of the second guide 111 is parallel to the length direction of the first guide 110. The second guide 111 can be mounted on the outer shell 40 of the frame. The height of the second guide 111 is different from that of the first guide 110. The cooperation of the first guide 110 and the second guide 111 can make the lens barrel 200 be mounted more firmly on the frame, and the movement of the lens barrel 200 is guided by both of them, so as to improve the stability and accuracy of the movement of the lens barrel 200 and avoid the deviation or inclination of the lens barrel 200 during the movement.

[0056] In one embodiment, as shown in FIGS. 3 and 8, the lens barrel 200 is further provided with a second sliding block 202, and the second sliding block 202 comprises two mutually perpendicular and connected plate portions, so that the second sliding block 202 can be hung on the second guide 111. When the connecting member 22 drives the lens barrel 200 to move, the second sliding block 202 moves along the length direction of the second guide 111.

[0057] In one embodiment, the connecting member 22 is a flexible rope. In this way, the rotation of the rotating structure 21 is easier to move the lens barrel 200 by pulling the rope 22. Further, the rope 22 has no elasticity, so that when the rotating structure 21 rotates, the rope 22 will not be stretched and deformed, and the rotation of the rotating structure 21 can more effectively drive the rope 22 to rotate.

[0058] In one embodiment, as shown in FIGS. 2, 3 and 10, for the same lens barrel 200, one end of the connecting member 22 of the adjusting part 20 corresponding to the lens barrel 200 is connected to the side of the lens barrel 200 away from the other lens barrel 200, and the other end is connected to the side of the lens barrel 200 facing the other lens barrel 200, and the connecting member 22 is wound around the side of the rotating structure 21. When the rotating structure 21 rotates in a first direction, the lens barrel 200 is moved away from the other lens barrel 200 by the connecting member 22, and when the rotating structure 21 rotates in a second direction opposite to the first direction, the lens barrel 200 is moved towards the other lens barrel 200 by the connecting member.

[0059] There is a friction force between the connecting member 22 and the rotating structure 21, and when the rotating structure 21 rotates, the part of the connecting member 22 wound on the rotating structure 21 will not slip. When the rotating structure 21 rotates in the first direction, the length of the part of the connecting member 22 between the side of the lens barrel 200 away from the other lens barrel 200 and the rotating structure 21 becomes smaller, and the length of the part of the connecting member 22 between the side of the lens barrel 200 facing the other lens barrel 200 and the rotating structure 21 becomes larger, so that the connecting member 22 drives the lens barrel 200 to move away from the other lens barrel 200. When the rotating structure 21 rotates in the second direction, the length of the part of the connecting member 22 between the side of the lens barrel 200 away from the other lens barrel 200 and the rotating structure 21 becomes larger, and the length of the part of the connecting member 22 between the side of the lens barrel 200 facing the other lens barrel 200 and the rotating structure 21 becomes smaller, so that the connecting member 22 drives the lens barrel 200 to move towards the other lens barrel 200. In this way, the movement of the lens barrel 200 in two directions can be realized by one connecting member 22.

[0060] The first direction of rotation of the rotating structure 21 of the two adjusting portions 20 can be the same or opposite. It should be noted that the winding direction of the connecting member 22 on the rotating structure 21 is related to the moving direction of the lens barrel 200. Taking FIG. 2 as an example, for the lens barrel 200' corresponding to the left eye of the user and the lens barrel 200" corresponding to the right eye of the user, if the winding direction of the connecting member 22 on the rotating structure 21 in the adjusting portion 20 corresponding to the lens barrel 200' is the same as the winding direction of the connecting member 22 on the rotating structure 21 in the adjusting portion 20 corresponding to the lens barrel 200", the first direction of rotation of the rotating structure 21 of the two adjusting portions 20 is opposite; if the winding direction of the connecting member 22 on the rotating structure 21 in the adjusting portion 20 corresponding to the lens barrel 200' is opposite to the winding direction of the connecting member 22 on the rotating structure 21 in the adjusting portion 20 corresponding to the lens barrel 200", the first direction of rotation of the rotating structure 21 of the two adjusting portions 20 is the same. For example, in the adjusting portion 20 corresponding to the lens barrel 200', when the connecting member 22 is wound on the rotating structure 21 in the counterclockwise direction, the lens barrel 200' moves away from the lens barrel 200" corresponding to the right eye of the user when the rotating structure 21 rotates in the counterclockwise direction, and the lens barrel 200' moves towards the lens barrel 200" corresponding to the right eye of the user when the rotating structure 21 rotates in the clockwise direction; in the adjusting portion 20 corresponding to the lens barrel 200", when the connecting member 22 is wound on the rotating structure 21 in the counterclockwise direction, the lens barrel 200" moves towards the lens barrel 200' when the rotating structure 21 rotates in the counterclockwise direction, and the lens barrel 200" moves away from the lens barrel 200' when the rotating structure 21 rotates in the clockwise direction.

[0061] In one embodiment, as shown in FIG. 3 and FIG. 11, the connecting member 22 comprises a first connecting segment 221 and a second connecting segment 222. For each lens barrel 200, one end of the first connecting segment 221 is connected to the side of the lens barrel 200 away from the other lens barrel 200, and the other end is connected to the rotating structure 21 adjusting the lens barrel 200, and one end of the second connecting segment 222 is connected to the side of the lens barrel 200 towards the other lens barrel 200, and the other end is connected to the rotating structure 21 adjusting the lens barrel 200. When the rotating structure 21 rotates in the first direction, the lens barrel 200 is moved away from the other lens barrel 200 by the first connecting segment 221, and when the rotating structure 21 rotates in the second direction opposite to the first direction, the lens barrel 200 is moved towards the other lens barrel 200 by the second connecting segment 222. The first direction of rotation of the rotating structure 21 of the two adjusting portions 20 is opposite. When the first connecting segment 221 and the second connecting segment 222 are independently connected to the rotating structure 21, the situation that the lens barrel spacing adjustment fails due to the slipping between the connecting member 22 and the rotating structure 21 when the rotating structure 21 rotates can be avoided.

[0062] In one embodiment, as shown in FIGS. 10-12, the rotating structure 21 comprises a rotating shaft 210, and the mounting portion is provided with a positioning column 113, the rotating shaft 210 is sleeved on the positioning column 113 and can rotate around the positioning column 113. The positioning column 113 can be arranged on the shell 40 of the frame. When the connecting member 22 is a one-piece structure, the connecting member 22 can be wound on the side wall of the rotating shaft 210. In some embodiments, the side of the rotating shaft 210 can be provided with a first threading fixing lug 211 for connecting the connecting member 22, the first threading fixing lug 211 is provided with a first threading hole 2111, and in the case that the connecting member 22 comprises a first connecting segment 221 and a second connecting segment 222, the end of the first connecting segment 221 connected with the rotating structure 21 can pass through the first threading hole 2111 and be tied to the first threading fixing lug 211, and the end of the second connecting segment 222 connected with the rotating structure 21 can also pass through the first threading hole 2111 and be tied to the first threading fixing lug 211.

[0063] In one embodiment, as shown in FIG. 14, the side of the rotating structure 21 is provided with an operating member 212, the operating member 212 comprises a plurality of anti-slip protrusions 2121, and the anti-slip protrusions 2121 are arranged at intervals along the rotating direction of the rotating structure 21. When the user needs to adjust the distance of the lens barrel 200, the user can use fingers to push the operating member 212, and use the operating member 212 to drive the rotating structure 21 to rotate. The anti-slip protrusions 2121 can increase the friction force when the user's fingers contact the operating member 212, so as to prevent the user's hands from slipping with the rotating structure 21.

[0064] In one embodiment, the operating member 212 can be sleeved on the end of the rotating shaft 210, the operating member 212 is provided with a square hole, and the end of the rotating shaft 210 is square-shaped to match the square hole of the operating member 212. In other embodiments, the rotating shaft 210 and the operating member 212 can be integrally formed, and the anti-slip protrusions 2121 can be arranged on the side wall of the end of the rotating shaft 210.

[0065] In one embodiment, as shown in FIGS. 10 and 11, one of the mounting portion and the rotating structure 21 is provided with a plurality of first limiting structures 12 arranged along the rotating direction of the rotating structure 21, and the other is provided with a matching structure 23 matched with each first limiting structure 12. When the rotating structure 21 rotates to different positions, the matching structure 23 matches with different first limiting structures 12 to lock the rotating structure 21 at different positions, so as to prevent the rotating structure 21 from rotating undesirably. In the embodiment shown in FIGS. 10 and 11, the mounting portion is provided with a plurality of first limiting structures 12, and the first limiting structures 12 are arranged on the shell 40. The rotating structure 21 is provided with at least one matching structure 23. In other embodiments, the rotating structure 21 is provided with a plurality of first limiting structures 12, and the mounting portion is provided with at least one matching structure 23.

[0066] In one embodiment, as shown in FIG. 11, the first limiting structure 12 is a limiting groove 121, and the cooperating structure 23 is a limiting protrusion 231. When the limiting protrusion 231 is located in the limiting groove 121, the position of the rotating structure 21 is fixed, so that the position of the lens barrel 200 remains unchanged. When the user needs to adjust the position of the lens barrel, an acting force is applied to the rotating structure 21, so that the limiting protrusion 231 can move out of the current limiting groove 121 and enter another limiting groove 121.

[0067] In one embodiment, as shown in FIG. 11 and FIG. 12, the surface of at least one of the cooperating structure 23 and the first limiting structure 12 is provided with a guide surface 1211, 2311, which is used to guide the movement of the cooperating structure 23 relative to the first limiting structure 12. The guide surface can reduce the resistance when the cooperating structure 23 and the first limiting structure 12 rotate relative to each other, avoid the cooperating structure 23 being stuck in the first limiting structure 12, reduce the difficulty of rotating the rotating structure 21, and facilitate the user operation. In the embodiments shown in FIG. 11 and FIG. 12, the top end of the limiting protrusion 231 is provided with an arc-shaped guide surface 2311, and the limiting groove 121 is provided with an arc-shaped guide surface 1211.

[0068] Specifically, the limiting groove 121 can be an arc-shaped ratchet groove, and the protrusion 231 can be a ratchet tooth provided on the sidewall of the rotating shaft 210. The structure cooperation of the ratchet teeth can realize step-by-step adjustment or locking at a specific position.

[0069] In one embodiment, as shown in FIG. 3 and FIG. 6, the adjusting part 20 further comprises at least one reversing piece 24, which is located on the side of the mounting structure 11 away from the other mounting structure 11, or between the two mounting structures 11. The connecting piece 22 passes through the reversing piece 24, and the reversing piece 24 is configured to make the extension direction of the part of the connecting piece 23 between the lens barrel connected thereto and the reversing piece 24 the same as the length direction of the first guide piece 110. When the extension direction of the connecting piece 22 is the same as the length direction of the first guide piece 110, the force direction of the connecting piece 22 is consistent with the direction of the movement of the lens barrel 200 along the first guide piece 110 during the pulling or releasing process, which helps to reduce the force required to pull the lens barrel 200 and facilitates the user operation.

[0070] In the embodiment shown in FIG. 3, each mounting structure 11 is provided with one reversing piece 24 on each of the left and right sides.
