Fig. 1 is a schematic diagram of augmented reality AR glasses 10 in the prior art and shows that different effects are presented when different users wear the AR glasses 10.AR glasses are devices linking a virtual world and a real world, through which a user can see both the real world and virtual content. The AR glasses 10 include a lens 1 and/or a lens 2. Lens 1 and/or lens 2 may be used to project or display a screen, such as screen 1 and/or screen 2. In one embodiment of the present application, lens 1 and/or lens 2 may project or display screen 1 and/or screen 2 through optical waveguide technology of monocular prism optical perspective or binocular prism optical perspective. The center point of the screen 1 is MC1, the center point of the screen 2 is MC2, it should be understood that, by designing, the center point MC1 of the screen 1 is on the same straight line with the center point of the lens 1, and the center point MC2 of the screen 2 is on the same straight line with the center point of the lens 2, then the distance between the center points MC1 and MC2 of the screens 1 and 2 is equal to the distance between the center points of the lenses 1 and 2, and is a fixed value D1, as shown in fig. 1a and 1 b. However, since the interpupillary Distance (IPD) between different users is different, wherein the interpupillary Distance is the Distance between the centers of the pupils of both eyes of a human, the effect of wearing the AR glasses 10 with the fixed value D1 by different users is different. FIG. 1a shows the interpupillary distance D of the user 1_IPD1Equal to the distance D1 between the center points of the lenses 1, 2, D_IPD1Therefore, when the user 1 wears the AR glasses 10, the pupil center points of the left/right eyes of the user 1 are substantially aligned with the center point of the lens 1/2 and the center point of the screen 1/2, and the user 1 can view the complete stereoscopic images on the screens 1 and 2 through the AR glasses 10. FIG. 1b shows the interpupillary distance D of the user 2_IPD2Is not equal to the distance D1 between the centre points of the lenses 1, 2, wherein D_IPD2And may be less than or greater than D1. In the embodiment shown in FIG. 1b, D_IPD2< D1, when the user 2 wears the AR glasses 10, the pupil center of his left/right eye, the center of the lens 1/2, and the center of the screen 1/2 are not in a straight line, and therefore, the visual effect of the user 2 watching the screens 1 and 2 through the AR glasses 10 is poor due to the mismatch of the pupillary distances of the user 2, and problems of unclear images, distortion, and the like may occur.

The embodiment of the application provides intelligent glasses, can adapt to the user of different interpupillary distances to improve the whole impression when the user wears glasses.

Fig. 2 is a perspective view of smart glasses 2 provided in an embodiment of the present application. Fig. 3 is a perspective assembly view of the smart glasses 2. Fig. 4 is a schematic diagram of an assembly process of the smart glasses 20. The smart glasses 2 may be AR glasses, in particular, light and thin AR glasses. The structure of the AR eyeglasses 2 is described below with reference to fig. 2, 3, and 4.

The AR glasses 2 include a first display assembly 20 and a second display assembly 21, the first display assembly 20 including a first frame 201, a first lens 202, and a first temple 204, the second display assembly 2 including a second frame 211, a second lens 212, and a second temple 214. Since the structure and positional relationship of the frame, lenses, and temples are well known to those skilled in the art, they are not described in detail in this application.

In the present application, the AR glasses 2 further comprise an adjustment assembly 22, the adjustment assembly 22 being connected to the first display assembly 20 and the second display assembly 21. Under the action of the adjusting component 22, the first display component 20 and the second display component 21 can move relatively to each other, so that the first frame 201 and the second frame 211 are close to or away from each other, and the first lens 202 and the second lens 212 are close to or away from each other, so that the distance D between the lens center points of the first lens 202 and the second lens 212 is obtained_ACan be adjusted, for example, turned down or turned up. Therefore, the AR glasses can adapt to different pupil distances of different users, and when the user wears the AR glasses, the distance between the first frame 201 and the second frame 211 can be adjusted, so that the picture of the screen can be adjusted to be clearer, or the user can adjust the distance D_AThe pupil distance is adjusted to be basically consistent with the pupil distance of the user, so that the visual experience of the user wearing the AR glasses can be improved.

As shown in fig. 2, in the process that the first frame 201 and the second frame 211 approach or separate from each other, the temple width D of the AR glasses is also changed_LWherein the width of the temple is D_LRefers to the distance between first temple 204 and second temple 214. In general, since the head circumference of a user with a large interpupillary distance is larger, the distance D between the center points of the left and right lenses of the AR glasses is set as the distance_AWhen the pupil distance of a user can be adapted, the width D of the glasses legs_LBut also to the head circumference of the user.

Distance D between lens central points of AR glasses 2 provided by the embodiment of the application_AMay be in the range of (58mm, 72mm), and the temple width D of the AR eyeglasses 2_LMay be in the range of (135mm, 149 mm). Since most users have interpupillary distances within this range (58mm, 72mm), the AR glasses 2 are able to fit most users and provide a comfortable wearing experience.

It should be understood that the temple of the AR glasses 2 may have different structures, for example, a rigid structure, or a flexible band-shaped structure, when the temple has a rigid structure, the AR glasses 2 may include two

separate temples

204 and 214, and the two

temples

204 and 214 are connected to the two

frames

204 and 214, respectively, as shown in fig. 2, wherein the distance between the two

temples

204 and 214 is the temple width D_L(ii) a When the temple has a flexible band structure, the AR glasses may include a flexible band having both ends connected to the two

frames

204 and 214, respectively, and at this time, since the flexible temple has no temple width, the temple width D is described as the temple width_LAs can be understood, the distance between the attachment of the

frames

204 and 214, respectively, to the flexible band. Therefore, in the present application, the specific structure of the temple 33 is not limited.

Therefore, the AR glasses can be suitable for users with different head circumferences, and the applicability and the wearing comfort of the AR glasses are improved.

Specifically, the adjustment assembly 22 includes a first bracket 203, a second bracket 213, and an adjustment member 23. Fig. 4 is an assembly schematic diagram of the AR glasses 2 provided in the embodiment of the present application. As shown in fig. 4a-4c, the first support 203 and the first lens 202 are mounted with respect to the first frame 201, and the second support 213 and the second lens 212 are mounted with respect to the second frame 211. Subsequently, as shown in fig. 4d, the adjusting member 23 is installed between the first bracket 203 and the second bracket 213 (the second bracket 213 is not shown in fig. 4 d), and is used for adjusting the distance between the first bracket 203 and the second bracket 213, so as to make the first lens 202 and the second lens 212 (the second lens 212 is not shown in fig. 4 d) approach each other or move away from each other.

In one embodiment of the present application, as shown in fig. 4a and 4b, the first bracket 203 is fixed to the first lens 202 and assembled together in the first frame 201, and the second bracket 213 is fixed to the second lens 212 and assembled together in the second frame 211. The fixing mode of the bracket and the lens can be gluing fixing (for example, fixing by adopting a dispensing mode), the buckle fixing (for example, one is provided with the buckle, the other is provided with the clamping groove, so that the detachable connection between the buckle and the clamping groove is realized through the matching of the buckle and the clamping groove), or fixing through a connecting piece, or fixing through other fixing modes.

In another embodiment of the present application, the first bracket 203 is fixed to the first frame 201, and the first lens 202 is assembled in the first frame 201, and the second bracket 213 is fixed to the second frame 221, and the second lens 212 is assembled in the second frame 211, wherein the fixing manner of the brackets and the frame may be gluing, fastening, bolting or other fixing manners.

In yet another embodiment of the present application, the first support 203 and the first frame 201 may also be an integrated structure, and the second support 213 and the second frame 221 may also be an integrated structure. The two integrated structures are connected and fixed through the adjusting piece 23, and the distance between the two integrated structures is adjusted through the adjusting piece 23. Wherein the integral structure of the frame and the frame is provided with an opening with sufficient size to accommodate/assemble the lens on the corresponding side.

After the carrier, the lenses, and the frame are assembled, both ends of the adjusting member 23 are connected to the

carriers

203, 213, respectively, to connect the first frame 201 and the second frame 211, and the distance between the first frame 201 and the second frame 211 is adjusted to be close to or away from each other by the relative movement of the adjusting member 23 and the

carriers

203, 213.

Since there is relative movement between the adjusting member 23 and the bracket 203/213 when adjusting the spacing of the frame, the adjusting member 23 and the bracket 203/213 can be of the same material to reduce wear during relative movement. For example, the materials are all metal materials, all plastic materials, or all other materials.

It should be understood that the adjusting member 23 and the bracket 203/213 may be of different materials. For example, the adjusting member 23 is made of metal, and the bracket 203/213 is made of non-metal.

In particular, the adjustment member 23 may be a rigid member, such as a metal member. Since the adjusting member 23 is used to connect and adjust the distance between the first bracket 203 and the second bracket 213, the rigid material may provide more reliable connection. The first bracket 203 and the second bracket 213 may be flexible members, such as plastic brackets, and have structures that cooperate with the adjusting members 23 to be respectively coupled with the adjusting members 23, and are respectively adjustably fixed.

In the embodiment of the application, the AR glasses 2 further comprise a nose pad 24 mounted on the adjustment piece 23, as shown in fig. 4 e. In one embodiment of the present application, the exposed portion of the adjusting member 23 is provided with a first magnetic member 230, the first magnetic member 230 can be disposed inside, outside or as a part of the adjusting member 23, and the extended portion of the nose pad 24 is provided with a second magnetic member or metal member 240 inside (i.e., toward the side where the adjusting member 23 is mounted). Therefore, the first magnetic member 230 and the second magnetic member or metal member 240 are magnetically attracted to each other. When the user adjusts the distance between the first frame 201 and the second frame 211 through the adjustment member 23, the displacement of the adjustment member 23 with respect to the first frame 201 and the displacement with respect to the second frame 211 may be different. By providing a plurality of first magnetic members 230 or providing a magnetic member 230 having a sufficient axial length on the adjuster 23, the nose pad 24 can have different attachment positions with respect to the adjuster 23, and preferably, the nose pad 24 is always attached to the middle between the first frame 201 and the second frame 211 regardless of whether the adjuster 23 is attached symmetrically with respect to the holder 203/213 or not, so that it is possible to prevent the two frames from being misaligned when the user wears the AR glasses.

It will be appreciated that the securing between the nose piece 24 and the adjustment member 23 may also be a glue fit, a snap fit, a bolt fit or other securing means. When the nose pads 24 are detachably connected to the adjusting member 23, a plurality of positions for mounting the nose pads 24 may be provided on the adjusting member 23 for the user to adjust. Only one position for mounting the nose pad 24 may be provided on the adjusting member 23, and in this case, the user should symmetrically adjust the relative positions of the adjusting member 23 and the first and

second brackets

203, 213 so that the nose pad 24 is substantially in the middle position of the first and

second brackets

203, 213.

In one embodiment of the present application, the nose piece 24 and the adjustment member 23 may be a unitary structure, which ensures that the user does not lose the nose piece 24 when using the AR glasses 2.

The structure of the adjusting member 23 and the bracket 203/213 in the adjusting assembly 22 and the assembly and adjustment thereof will be described below with reference to fig. 5 to 7. Fig. 5 is a perspective view and a sectional view of the adjusting member 23, fig. 6 is a perspective view and a sectional view of the bracket 203/213, and fig. 7 is a schematic view of the adjustment performed by the adjustment assembly 22.

In the embodiment shown in fig. 5, among others, fig. 5b is a cross-sectional view a-a' in fig. 5 a. The adjuster 23 is a hollow structure having a substantially rectangular parallelepiped shape, and has a first end 57 and a second end 59, and a body extending between the first end 57 and the second end 59, and a cavity 55 is defined in the extending body, wherein the cavity 55 is used for arranging a Circuit board, such as a Flexible Printed Circuit (FPC), to connect/conduct Circuit modules on the left and right sides of the AR glasses 2, such as a first Circuit module, e.g., a display module, provided in the first display module 20, and a second Circuit module, e.g., a power supply module, provided in the second display module 21. The first and second circuit modules are connected by a circuit board in the cavity 55 to supply power to the display module, for example, through the power supply module. The cavity 55 may be provided with an image pickup device or other devices, so that the AR glasses 2 are integrated with functions such as image pickup. It should be understood that the first circuit module in the first display assembly 20 may be disposed relative to the first frame 201, including being disposed in the first frame 201, and/or in the first temple 204, and/or in the first support 203; similarly, the second circuit module in the second display assembly 21 may be disposed relative to the second frame 211, including being disposed in the second frame 211, and/or in the second temple 214, and/or in the second support 213.

The adjustment member 23 has at least four outer surfaces that extend between the first end 57 and the second end 59 to form a generally rectangular parallelepiped configuration. Specifically, the adjusting member 23 has a first surface 52 and a second surface 54 substantially opposite to the first surface 52, and further has a third surface 56 and a fourth surface 58 substantially opposite to the third surface 56, wherein the four surfaces are used for forming a cavity 55 to limit a moving space of the circuit board arranged in the cavity 55, for example, as shown in fig. 5a, a moving space of the circuit board (not shown in the figure) in the up-and-down direction in the cavity 55 is limited.

Referring to FIG. 5b, a first recess 50 is provided in first face 52 of adjustment member 23 for engaging a corresponding structure on bracket 203/213 to adjustably fix the relative position of adjustment member 23 and bracket 203/213. A first projection 53 is provided on second face 54 of adjustment member 23 for engaging a stop structure on bracket 203/213 to limit movement of adjustment member 23 in a direction away from bracket 203/213 and out of engagement with bracket 203/213.

In the embodiment shown in fig. 5, the adjustment member 23 has two first recesses 50 and two first projections 53, which are shown disposed proximate the first end 57 and proximate the second end 59, respectively. First recess 50 and first projection 53 proximate first end 57 are for engaging one of brackets 203/213, and first recess 50 and first projection 53 proximate second end 59 are for engaging the other of brackets 203/213. Therefore, the adjusting member 23 can move relative to the first bracket 203 and the second bracket 213, i.e., the relative positions between the adjusting member 23 and the first bracket 203 and the second bracket 213 can be adjusted and stopped, respectively.

In a specific embodiment, two first recesses 50 and two first protrusions 53 are respectively disposed on the adjusting member 23 at left-right symmetry, and the user can symmetrically adjust the positions of the first bracket 203 and the second bracket 213 with respect to the adjusting member 23, i.e., symmetrically adjust the first display assembly 20 and the second display assembly 21 shown in fig. 2. It should be understood that although the adjusting member 23 is a symmetrical structure, the user can adjust the first display module 20 and the second display module 21 asymmetrically, so as to meet the requirement of the user according to the actual situation, and improve the comfort of the user wearing the AR glasses.

In another specific embodiment, the two first recesses 50 and the two first protrusions 53 are respectively provided at asymmetrical positions on the adjuster 23. Therefore, the adjusting member 23 can be designed to avoid hardware structures such as a circuit board and a display module in the AR glasses 2, and it is not necessary to design the adjusting member 23 symmetrically. For the asymmetric adjusting piece 23, the user can adjust the relative positions of the adjusting piece with the first support 203 and the second support 213 according to actual conditions, so as to meet the wearing requirements of the user.

In another embodiment of the present application, the adjustment member 23 may include only one first recess 50 and one first projection 53, disposed at a position near the first end 57, or disposed at a position near the second end 59. For example, when the first concave portion 50 and the first convex portion 53 are disposed near the first end 57 and cooperate with the first support 203 to perform position adjustment with respect to the adjusting member 23, the second end 59 of the adjusting member 23 may be fixed to the second support 213, or the adjusting member 23 and the second support may be an integrated structure that achieves mutual approaching or distancing between the first frame 201 and the second frame 211 by moving relative to the first support 203.

Accordingly, in one embodiment of the present application, the first bracket 203 and the second bracket 213 may be structures that are symmetrical to each other or asymmetrical to each other. In another embodiment of the present application, the first bracket 203 includes a structure for adjusting and stopping in cooperation with the adjusting member 23, and the second bracket 213 includes a structure for fixing in cooperation with the adjusting member 23, i.e., the second bracket 213 does not need to have a structure for adjusting and stopping in cooperation with the adjusting member 23.

The specific structure of the second bracket 213 and how to adjust the position and stop the position relative to the adjusting member 23 will be described below by taking the second bracket 213 as an example. It should be understood that the first bracket 203 may have a completely symmetrical structure with the second bracket 213 and symmetrically perform position adjustment and stop with respect to the adjusting member 23.

In the embodiment shown in fig. 6, in which fig. 6a shows the second bracket 213, fig. 6B is a cross-sectional view of the second bracket 213 in fig. 6a at B-B'. Bracket 213 has an upper surface 66 and a lower surface 68. In one embodiment, when the stand 213 is assembled in the frame by gluing with the lens, the lower surface 68 of the stand 213 is glued with the lens and the upper surface 66 of the stand 213 is assembled against the inside of the frame. In this embodiment, the upper surface 66 of the support 213 matches the inside contour of the frame and the lower surface 68 of the support 213 matches the outside contour of the lens, for example, the upper surface 66 may be a curved, flat or contoured surface that matches the frame and the lower surface 68 may be a curved (including concave) or flat surface that matches the lens.

In the embodiment shown in fig. 6, upper surface 66 and lower surface 68 are both curved and meet at first end 67 and second end 69 of bracket 213, respectively, and extend between first end 67 and second end 69 of bracket 213.

As shown in fig. 6a, the bracket 213 is provided with a first recess 65 near the first end 67, the first recess 65 presenting an opening 62 on the upper surface 66, wherein the first recess 65 extends from the opening 62 in the direction from the first end 67 to the second end 69, thereby providing a sliding track for the adjustment member 23, as shown in fig. 6 b. Specifically, the second end 59 of the adjusting member 23 is inserted into the first recess 65 of the second bracket 213 from the opening 62 of the second bracket 213 and slides in the track provided by the first recess 65, wherein the track provided by the first recess 65 has a tip 64, and the tip 64 may be a protrusion 64 on the inner surface of the first recess 65 or a shoulder 64 connecting the first recess 65 and the second recess 651, and the protrusion 64 or the shoulder 64 may limit the sliding stroke of the second end 59 of the adjusting member 23 in the first recess 65 of the second bracket 213.

Fig. 6b shows a configuration in which the second bracket 213 is fitted with the adjusting piece 23 to adjust and stop. Specifically, first recess 65 of second leg 213 includes a first inner surface 652, and a second inner surface 654 generally opposite first inner surface 652. Wherein a second protrusion 60 is provided on the first inner surface 652 for engaging the first recess 50 of the adjusting member 23 near the second end 59, and wherein when the second end 59 of the adjusting member 23 is moved within the first recess 65 of the second bracket 213, the first recess 50 near the second end 59 moves relative to the second protrusion 60 of the second bracket 213 and at least partially mates with the second protrusion 60, thereby adjustably fixing (e.g., snapping) the relative position of the adjusting member 23 and the second bracket 213. A stop formation 63 is provided on the second inner surface 654 for abutting the first projection 53 on the adjustment member 23 adjacent the second end 59 to prevent the second end 59 of the adjustment member 23 from moving out of the first recess 65 of the second bracket 213.

For example, when the second end 59 of the adjusting member 23 moves in the first recess 65 of the second bracket 213 in the direction F as shown in the drawing, the first protruding portion 53 near the second end 59 moves away from the limiting structure 63 on the second bracket 213, and when the second end 59 of the adjusting member 23 moves in the first recess 65 of the second bracket 213 in the direction opposite to the direction F as shown in the drawing, the first protruding portion 53 near the second end 59 moves close to the limiting structure 63 on the first bracket 203 until the first protruding portion 53 abuts against the limiting structure 63, so that the limiting structure 63 can limit the second end 59 of the adjusting member 23 without affecting the sliding of the second end 59 of the adjusting member 23 in the track defined by the first recess 65 of the second bracket 213, the adjusting member 23 is prevented from falling off the second bracket 213, and the limiting structure 63 has the advantage of simple structure.

Please refer to fig. 5b and fig. 6b simultaneously. In the embodiment shown in fig. 5b, the first recessed portion 50 of the adjustment member 23 has a plurality of grooves 51 recessed from a first face 52. In the embodiment shown in fig. 6b, the second protrusion 60 of the second bracket 213 has a plurality of protrusions 61 protruding from the first inner surface 652. When the adjusting member 23 and the second bracket 213 are cooperatively moved, at least one groove 51 of the first recessed portion 50 near the second end 59 may be made to mate with the protrusion 61 of the second protruding portion 60, such as the protrusion 61 snaps into the groove 51, thereby adjustably snapping the adjusting member 23 and the second bracket 213.

In one embodiment of the present application, the second protrusion 60 of the bracket 203/213 may be an elastic member, for example, including at least a portion of an elastic material, and the second protrusion 60 can be elastically deformed when the second end 59 of the adjusting member 23 moves along the first recess 65 of the second bracket 213, so as to reduce the resistance of the adjusting member 23 during movement and improve the reliability of the engagement between the second protrusion 60 and the first recess 50.

When the second protrusion 60 of the second bracket 213 is engaged with the first recess 50 of the adjusting member 23, in an embodiment, the second protrusion 60 as an elastic member may be in an elastic release state, i.e., an undeformed state, and at this time, the second bracket 213 may be engaged with the adjusting member 23 by the protrusion 61 of the second protrusion 60 being engaged into the groove 51 of the first recess 50. In another embodiment, the second protrusion 60 as an elastic member may be in an elastically compressed state or an expanded state, i.e., a deformed state, in which, in addition to the protrusion 61 being caught in the groove 51, the pressure between the second bracket 213 and the adjusting member 23 is further increased by a resilient force generated by the compression amount or the expansion amount of the second protrusion 60, and the frictional force at least in the F direction is further increased to further improve the reliability of the first bracket 203 being caught with the adjusting member 23.

The outer contours of the plurality of protrusions 61 of the second protruding portion 60 may be arc-shaped, and correspondingly, the outer contours of the plurality of grooves 51 of the first recessed portion 50 may also be arc-shaped, so that the protrusions 61 and the grooves 51 smoothly transition, thereby reducing resistance during relative movement between the adjusting member 23 and the second bracket 213, reducing wear of the protrusions 61 and the grooves 51, and prolonging service life.

In one embodiment of the present application, the second projecting portion 60 may be, for example, an elastic rack 60, and the plurality of protrusions 61 on the second projecting portion 60 are a plurality of protrusions 61 on the elastic rack 60. The first recess 50 may be a spline 50 to engage the elastic rack, and the plurality of grooves 51 on the first recess 50 are a plurality of through holes 51 on the spline 50. When the adjusting member 23 is snapped into engagement with the second bracket 213, the resilient rack 60 near the second end 59 of the adjusting member 23 engages the tooth slot 50 of the second bracket 213, wherein at least a portion of the plurality of protrusions 61 of the resilient rack 60 snap into corresponding through holes 51 in the tooth slot 50.

When the adjusting member 23 is snapped into the first recess 65 of the first bracket 203 by an external force, the snapping and stopping process can be symmetrical with the above-mentioned snapping into the second bracket 213. As shown in fig. 7a, the adjustment element 23 cooperates with the resilient toothed rack 60 of the first bracket 203 at the toothed slot 50 near the first end 57, at least a portion of the resilient toothed rack 60 is snapped into at least a portion of the toothed slot 50, i.e. at least one protrusion 61 is snapped into the corresponding through hole 51, so that the adjustment element 23 is adjustably snapped into engagement with the first bracket 203. When the external force disappears, the adjusting piece 23 and the first bracket 203 cannot move, so that the relative position of the adjusting piece 23 and the first bracket 203 is fixed.

In one embodiment of the present application, the first recess 50 of the adjusting member 23 may be an elastic member, for example, including at least a portion of an elastic material, in which case the third surface 56 of the first recess 50 may be a deformable material, or the third surface 56 may be omitted directly, so as to provide a compression or expansion elastic space for the first recess 50, and when the first end 57 of the adjusting member 23 moves along the first recess 65 of the first bracket 203, the first recess 50 can be elastically deformed, so as to reduce the resistance of the adjusting member 23 during the movement process and improve the reliability of the engagement between the first recess 50 and the second protrusion 60. In another embodiment of the present application, the first recess 50 of the adjusting member 23 and the second protrusion 60 of the bracket 203/213 may both be elastic members, and both the first recess 50 of the adjusting member 23 near the first end 57 and the second protrusion 60 of the first bracket 203 may be elastically deformed in the same or opposite directions when the adjusting member 23 moves along the first recess 65 of the first bracket 203.

In one embodiment of the present application, the structure on the adjustment member 23 and the bracket 203/213 for snap-fitting may be reversed, i.e., the second protrusion 60 may be disposed on the adjustment member 23 and the first recess 50 may be disposed on the bracket 203/213. It will be appreciated that the snap-fit between the second projection 60 provided on the adjuster 23 and the first recess 50 provided on the bracket 203/213 remains the same or similar to the previous embodiment. In one embodiment, when the first end 57 of the adjusting member 23 is forced to snap into the first recess 65 of the first bracket 203, the resilient rack 60 of the adjusting member 23 adjacent to the first end 57 engages the slot 50 of the first bracket 203 and moves relative thereto, thereby adjustably snapping the adjusting member 23 to the first bracket 203. The sliding engagement of the elastic rack 60 on the adjusting member 23 with the tooth slot 50 on the first bracket 203 can adjust the distance between the first display module 20 and the second display module 21 on the AR glasses 2.

It should be understood that when the adjusting member 23 is assembled with the first bracket 203, and the adjusting member 23 is caught in the first recess 65 of the first bracket 203 and moved in the direction F shown in fig. 7, the elastic rack 60 is moved in the direction opposite to the direction F with respect to the teeth grooves 50. After the adjusting member 23 moves a distance in the direction F relative to the first bracket 203, as shown in fig. 7a, the first protrusion 53 of the adjusting member 23 abuts against the limit structure 63 of the first bracket 203 to prevent the adjusting member 23 from moving in the direction opposite to the direction F and falling off from the first bracket 203. When the relative positions of the adjusting member 23 and the second bracket 213 are symmetrical to that shown in fig. 7a, the adjusting member 22 provides the maximum distance between the first display assembly 20 and the second display assembly 21, i.e. the distance D between the lens center points of the first lens 202 and the second lens 212_AAt a maximum, for example, approximately 72 mm. Accordingly, at this time, the temple width D of the AR eyeglasses 2_LAlso has a maximum value, for example approximately 149 mm.

When the adjusting member 23 is further moved by an external force in the first recess 65 of the first bracket 203, such as in the direction F, i.e. during the movement of the adjusting assembly 22 from the position shown in fig. 7a to the position shown in fig. 7b, the resilient rack 60 is further moved in the direction opposite to the direction F relative to the toothed slot 50. When the first end 57 of the adjustment member 23 abuts the end 64 of the track provided by the first recess 65 (e.g., the projection 64 or the shoulder 64), the distance of movement of the adjustment member 23 relative to the first bracket 203 is maximized as shown in fig. 7 b. When the relative positions of the adjusting member 23 and the second bracket 213 are symmetrical to that shown in fig. 7b, the adjusting member 22 provides the minimum distance between the first display assembly 20 and the second display assembly 21, i.e. the distance D between the lens center points of the first lens 202 and the second lens 212_AAnd may be a minimum of, for example, 58 mm. Accordingly, at this time, the temple width D of the AR eyeglasses 2_LAlso has a minimum value, which may be 135mm, for example.

Thus, the user can adjust the relative position of the adjustment member 23 and the first support 203 to any intermediate position between fig. 7a and 7b (including the positions shown in fig. 7a and 7 b) by applying opposing pulling forces to the first support 203 and the second support 213 in the direction F, or applying opposing pulling forces to the adjustment member 23 and the first support 203 in the direction F.

As described above, the AR glasses 2 achieve the adjustment of the spacing between the first display assembly 20 and the second display assembly 21 thereof by the adjustment assembly 22, and the adjustable range thereof may be such that the temple width D_LWithin a range (135mm, 149mm) and may be such that the distance D between the lens center points of the first and

second optics

202, 212_AIn the range (58mm, 72 mm). Because the scope of above-mentioned mirror leg width can satisfy most users 'wearing travelling comfort, and because most users' interpupillary distance is in scope (58mm, 72mm), consequently, through the regulation of adjusting part 22, this AR glasses 2 can adapt to most users, has improved the flexibility that this AR glasses 2 wore for different users, and has guaranteed the travelling comfort when different users wore.

As shown in fig. 8, a circuit board 80, such as a flexible circuit board, is disposed in the AR glasses 2. The flexible circuit board 80 passes through the adjusting assembly 22 and connects the left and right display modules of the AR glasses 2. Specifically, the flexible circuit board 80 is disposed along the cavity 55 of the adjuster 23 and continuously passes through the first bracket 203 and the second recess 651 of the second bracket 213. In one embodiment of the present application, the flexible circuit board 80 is designed with redundant portions that are expanded or compressed as the adjustment member 23 is moved relative to the first bracket 203 and the second bracket 213.

Fig. 9 shows a schematic diagram of the circuit board 80 and a perspective view of the circuit board 80 mounted to the AR glasses 2.

As shown in fig. 9a, the flexible circuit board 80 includes left and right speakers 91, left and right screens 92, a board stage device 93 positioned between the left and right screens 92, and redundant portions 94 of the circuit board 80 positioned between the board stage device 93 and the screens 92, respectively. In one embodiment of the present application, both the off-board device 93 and the redundant portion 94 may be flexible. In yet another embodiment of the present application, only the redundant portion 94 may be designed to be flexible.

As shown in fig. 9b, the left and right speakers 91 and the left and right screens 92 are disposed substantially in the stand 203/213, the board step member 93 is disposed substantially in the adjusting member 23, and the redundant portion 94 may be disposed in the adjusting member 23 or the stand 203/213. When the adjusters 23 are moved relative to the bracket 203/213 such that the frames 201/211 are brought closer to each other to a minimum spacing, the redundant portion 94 is compressed in the adjusters 23, the bracket 203/213, or the overlapping portion of the adjusters 23 and the bracket 203/213; when the adjusters 23 are moved relative to the bracket 203/213 such that the frames 201/211 are spaced apart from each other to a maximum distance, the redundant portion 94 is deployed in the adjuster 23, the bracket 203/213, or an overlapping portion of the adjusters 23 and the bracket 203/213.
