The singular forms of "a", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

It should be understood that the term "and/or" used in this article is only an association relationship describing associated objects, which means that there can be three types of relationships, for example, A and/or B, which can mean: A alone exists, and both A and A B, there are three cases of B alone. In addition, the character "/" in this text generally indicates that the associated objects before and after are in an "or" relationship.

It should be noted that the “upper”, “lower”, “left”, “right” and other directional words described in the embodiments of this application are described from the angle shown in the drawings, and should not be construed as implementation of this application. The limit of the case. In addition, in the context, it should also be understood that when it is mentioned that an element is connected "on" or "under" another element, it can not only be directly connected to the other element "on" or "under", but also It is indirectly connected "on" or "under" another element through an intermediate element.

FIG. 1 is a schematic diagram of the augmented reality AR glasses 10 in the prior art, and shows that when different users wear the AR glasses 10, different effects are presented. AR glasses are a linking device between the virtual world and the real world. Through AR glasses, users can see the real world and virtual content at the same time. Among them, 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 screens, such as screen 1 and/or screen 2. In an embodiment of the present application, the lens 1 and/or the lens 2 can project or display the screen 1 and/or the screen 2 through the optical waveguide technology of monocular prism optical see-through or binocular prism optical see-through. The center point of screen 1 is MC1, and the center point of screen 2 is MC2. It should be known that through design, the center point MC1 of screen 1 and the center point of lens 1 are in a straight line, and the center point of screen 2 MC2 and lens 2 The center point is on a straight line, then the distance between the center points MC1 and MC2 of the screens 1, 2 is equal to the distance between the center points of the lenses 1, and both are fixed values D1, as shown in Figures 1a and 1b Show. However, because the inter pupillary distance (IPD) of different users is not the same, where the inter pupillary distance refers to the distance between the center points of the pupils of both eyes of a person, different users wear the AR glasses 10 with the above-mentioned fixed value D1. The effects are all different. Figure 1a shows that the interpupillary distance D _{IPD1 of} user 1 and the distance D1 between the center points of lenses 1 and 2 are equal, D _IPD1 = D1. Therefore, when user 1 wears AR glasses 10, the center of the pupil of his left/right eye The point is roughly aligned with the center point of the lens 1/2 and the center point of the screen 1/2 on a straight line. The user 1 can view the complete three-dimensional images on the screens 1 and 2 through the AR glasses 10. Fig. 1b shows that the interpupillary distance D _{IPD2 of the} user 2 and the distance D1 between the center points of the lenses 1 and 2 are not equal, where D _IPD2 may be smaller or larger than D1. In the embodiment shown in Fig. 1b, D _IPD2 <D1, when the user 2 wears AR glasses 10, the pupil center point of his left/right eye is the center point of 1/2 of the lens and the center point of the screen 1/2. They are not in a straight line. Therefore, due to the mismatch of the interpupillary distance of the user 2, the visual effect of viewing the screens 1 and 2 through the AR glasses 10 is very poor, and problems such as unclear images and distortion may occur.

The embodiment of the present application provides a smart glasses that can adapt to users with different interpupillary distances, so as to improve the user's overall look and feel when wearing the glasses.

FIG. 2 is a perspective view of the smart glasses 2 provided by an embodiment of the application. FIG. 3 is a three-dimensional assembly diagram of the smart glasses 2. FIG. 4 is a schematic diagram of the assembly process of the smart glasses 20. The smart glasses 2 may be AR glasses, especially a thin and light AR glasses. Hereinafter, the structure of the AR glasses 2 will be described with reference to FIGS. 2, 3 and 4.

The AR glasses 2 includes a first display assembly 20 and a second display assembly 21. The first display assembly 20 includes a first spectacle frame 201, a first lens 202, and a first temple 204, and the second display assembly 2 includes a second spectacle frame 211 , The second lens 212, and the second temple 214. Since the structure and positional relationship of the spectacle frame, the lens, and the temples are well-known to those skilled in the art, it will not be repeated in this application.

In the present application, the AR glasses 2 further include an adjustment component 22 which is connected to the first display component 20 and the second display component 21. Under the action of the adjusting assembly 22, the first display assembly 20 and the second display assembly 21 can move relative to each other, so that the first frame 201 and the second frame 211 are close to or away from each other, so that the first lens 202 and the second lens 212 are close to each other or far away from each other, so that the distance D _A between the lens center points of the first lens 202 and the second lens 212 can be adjusted, for example, reduced or increased. Therefore, the AR glasses can be adapted to different interpupillary distances of different users. When the user wears the AR glasses, the distance between the first frame 201 and the second frame 211 can be adjusted to adjust the screen image more clearly. Or, in other words, the user can _{adjust the above-mentioned distance D A} to be basically consistent with the interpupillary distance of the user, so that the user's visual experience when wearing the AR glasses can be improved.

As illustrated, the process 201 211 and the second frame toward each other or away from each other in a first frame, but also to change the AR glasses temple width D _L 2, wherein D _L is the width of the temple of the first mirror means The distance between the leg 204 and the second temple 214. Normally, a user with a larger interpupillary distance has a larger head circumference. Therefore, when the distance D _A between the center points of the left and right lenses of the AR glasses can be adapted to the interpupillary distance of a user, the width of the temples _DL can also be applied to the user's head circumference.

_{The distance D A} between the lens center points of the AR glasses 2 provided by the embodiment of the present application may be in the range of (58 mm, 72 mm), and the temple width D _{L of} the AR glasses 2 may be in the range of (135 mm, 149 mm). Since the interpupillary distance of most users is within this range (58mm, 72mm), the AR glasses 2 can be suitable for most users and bring a comfortable wearing experience.

It should be understood that the temples of the AR glasses 2 may have different structures, for example, it may be a rigid structure or a flexible belt-like structure. When the temples are of a rigid structure, the AR glasses 2 may include two parts. The

temples

204 and 214 are arranged in the body, and the

temples

204 and 214 are connected to the two

temples

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

temples

204 and 214 is the above-mentioned temple width D _L ; When the temples have a flexible belt structure, the AR glasses may include a flexible belt, and the two ends of the flexible belt are connected to the two

frames

204 and 214 respectively. At this time, since the flexible temples do not have the width of the temples, The above-mentioned temple width _DL can be understood as the distance between the joints of the

frames

204 and 214 and the flexible belt. Therefore, in this application, the specific structure of the temple 33 is not limited.

Therefore, the augmented reality AR glasses can be applied to users with different head circumferences, and the applicability of the augmented reality AR glasses and the comfort of wearing by the user are improved.

Specifically, the adjustment assembly 22 includes a first bracket 203, a second bracket 213, and an adjustment member 23. FIG. 4 is a schematic diagram of the assembly of AR glasses 2 provided by an embodiment of the application. As shown in FIGS. 4a-4c, the first bracket 203 and the first lens 202 are installed relative to the first lens frame 201, and the second bracket 213 and the second lens 212 are installed relative to the second lens 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. 4d), and is used to adjust the difference between the first bracket 203 and the second bracket 213. The distance between the first lens 202 and the second lens 212 (the second lens 212 is not shown in FIG. 4d) is close to or far away from each other.

In an embodiment of the present application, as shown in FIGS. 4a and 4b, the first bracket 203 is fixed to the first lens 202 and assembled into the first lens frame 201 together, and the second bracket 213 is fixed to the second lens 212, And assembled into the second mirror frame 211 together. Among them, the fixing method of the bracket and the lens can be gluing fixation (for example, fixation by dispensing glue), buckle fixation (for example, one has a buckle, and the other has a card slot, so as to achieve through the cooperation of the buckle and the card slot. Removable connection between the two), or fixed by connecting pieces, or by other fixing methods.

In another embodiment of the present application, the first bracket 203 is fixed to the first lens frame 201, and the first lens 202 is assembled in the first lens frame 201, and the second bracket 213 is fixed to the second lens frame 221, and the second lens 212 is assembled in the second mirror frame 211, wherein the fixing method of the bracket and the mirror frame may be gluing fixing, buckle fixing, bolt fixing or other fixing methods.

In another embodiment of the present application, the first bracket 203 and the first spectacle frame 201 may also be an integrated structure, and the second bracket 213 and the second spectacle frame 221 may also be an integrated structure. The two integrated structures are connected and fixed by an adjusting member 23, and the distance between the two integrated structures is adjusted by the adjusting member 23. Wherein, an opening of sufficient size is left in the integrated structure of the bracket and the frame to accommodate/assemble the lens on the corresponding side.

After the bracket, lens, and frame are assembled, the two ends of the adjusting member 23 are connected to the

brackets

203 and 213, respectively, so as to connect the first frame 201 and the second frame 211, and the relative movement of the adjusting member 23 and the

brackets

203, 213 Adjust the distance between the first spectacle frame 201 and the second spectacle frame 211 so that they are close to each other or far away from each other.

Since there is relative movement between the adjusting member 23 and the bracket 203/213 when the distance between the mirror frames is adjusted, the adjusting member 23 and the bracket 203/213 may be made of the same material to reduce wear during relative movement. For example, they are all made of metal, all made of plastic, or all made of other materials.

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

Specifically, the adjusting 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 can provide a more reliable connection. The first bracket 203 and the second bracket 213 may be flexible members, such as plastic brackets, and have a structure that cooperates with the adjusting member 23 to connect with the adjusting member 23 respectively, and the two are respectively adjustable and fixed.

In the embodiment of the present application, the AR glasses 2 further include a nose pad 24, which is mounted on the adjusting member 23, as shown in FIG. 4e. In an embodiment of the present application, the exposed part of the adjusting member 23 is provided with a first magnetic member 230, and the first magnetic member 230 may be provided inside or outside of the adjusting member 23 or as a part of the adjusting member 23. The inner side of the extension of the holder 24 (that is, the side facing the installation of the adjusting member 23) is provided with a second magnetic member or metal member 240. Therefore, the first magnetic member 230 and the second magnetic member or metal member 240 are installed by magnetic attraction. When the user adjusts the distance between the first spectacle frame 201 and the second spectacle frame 211 through the adjustment member 23, the displacement of the adjustment member 23 relative to the first spectacle frame 201 and the displacement relative to the second spectacle frame 211 may be different. By arranging a plurality of first magnetic members 230 on the adjusting member 23, or providing a magnetic member 230 with sufficient axial length, the nose pad 24 can have a different installation position relative to the adjusting member 23. Preferably, regardless of the adjusting member 23 is installed and adjusted symmetrically with respect to the bracket 203/213. The nose pad 24 is always installed in the middle of the first frame 201 and the second frame 211, so as to avoid the deviation of the two frames when the user wears AR glasses.

It should be understood that the fixing method between the nose pad 24 and the adjusting member 23 may also be glued fixing, snap fixing, bolt fixing or other fixing methods. When the nose pad 24 and the adjusting member 23 are detachably connected, the adjusting member 23 may provide a plurality of positions for installing the nose pad 24 for the user to make adaptive adjustments. The adjusting member 23 may also provide only one position for installing the nose pad 24. At this time, the user should symmetrically adjust the relative positions of the adjusting member 23 and the first bracket 203 and the second bracket 213, so that the nose pad 24 is basically in the first position. The middle position of a bracket 203 and a second bracket 213.

In an embodiment of the present application, the nose pad 24 and the adjusting member 23 may be an integrated structure, which can ensure that the user does not lose the nose pad 24 when using the AR glasses 2.
