[0048] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0051] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0052] Example

[0053] The fundamental principle of AR (Augmented Reality) glasses lies in the combination of optical waveguide technology and micro-projection technology. One such technology provides smart glasses that project images onto the edges of the lenses using micro-projectors located at the temples. These images are then transmitted through optical waveguide structures on the lenses to the viewer's field of vision, thus achieving the augmented reality effect. Therefore, the placement of the micro-projector is crucial; precise alignment during assembly is essential to achieve the desired AR effect.

[0054] However, in related technologies, it is difficult to accurately align the projector during installation, which can easily lead to misalignment and scrapping of the projector, increasing manufacturing costs.

[0055] This embodiment provides an alignment structure 20 and smart glasses 100, which can solve the above problems and reduce manufacturing costs. The following will describe them by way of example with reference to the accompanying drawings.

[0056] Figure 1 This is a schematic diagram of the structure of the smart glasses 100 in one embodiment of this application; Figure 2 for Figure 1 A schematic diagram of the frame 40, lens 10, alignment structure 20 and projector 30 in the embodiment shown. Figure 3 for Figure 1 Exploded view of the frame 40, lens 10, alignment structure 20 and projector 30 in the illustrated embodiment; Figure 4 for Figure 1 A partial structural schematic diagram of the alignment structure 20, projector 30, and lens 10 in the illustrated embodiment. Figure 5 for Figure 1 A schematic diagram of the assembly state of the lens 10 and the alignment structure 20 in the embodiment shown. Figure 6 for Figure 1 A schematic diagram of the assembly state of the lens 10, the alignment structure 20, and the projector 30 in the illustrated embodiment. Figure 7 for Figure 1 Another assembly state diagram of the lens 10, alignment structure 20 and projector 30 in the illustrated embodiment.

[0057] See Figures 1 to 3 This embodiment provides a smart glasses 100, including a lens 10, an alignment structure 20, and a projector 30. For example... Figure 4 As shown, the alignment structure 20 includes a main body 21, which includes a fitting portion 211 and a protrusion 212. The fitting portion 211 is fitted to the inner side of the lens 10 along the thickness direction and has a first alignment hole 211a. The protrusion 212 protrudes beyond the outer contour of the lens 10. The projector 30 passes through the first alignment hole 211a and is fitted to the lens 10.

[0058] Thus, before assembling the projector 30 onto the lens 10, the alignment structure 20 can be installed onto the lens 10 first (see...). Figure 5 Then install the projector 30 into the first alignment hole 211a (see...). Figure 6 This allows the alignment device for aligning the projector 30 to align within a limited range of the first alignment hole 211a, thereby increasing the alignment accuracy of the projector 30. During projector 30 assembly, if the projector 30 is misaligned relative to the lens 10, the projector 30 will first contact the alignment structure 20 (see...). Figure 7This avoids the projector 30 being directly attached to the lens 10. Therefore, it allows the projector 30 to re-align when it is misaligned relative to the lens 10, thereby reducing the probability of alignment failure when the projector 30 is attached to the lens 10, reducing the scrap rate, and thus reducing manufacturing costs.

[0059] In some embodiments, such as Figure 4 As shown, the diameter of the first alignment hole 211a is 0.5 mm to 0.7 mm larger than the diameter of the projector 30 to provide a certain gap for easy installation of the projector 30.

[0060] Figure 8 for Figure 1 A partial structural schematic diagram of the alignment structure 20, lens 10, and frame 40 in the illustrated embodiment.

[0061] In some embodiments, such as Figure 4 As shown, the protrusion 212 is provided with a second alignment hole 212a, which extends along the thickness direction of the lens 10. (Combined with...) Figure 3 As shown, the smart glasses 100 also includes a frame 40, which has a lens groove 40a for accommodating the lens 10, such as... Figure 8 As shown, the frame 40 is provided with an alignment member 41, which passes through the second alignment hole 212a. In this way, the alignment member 41 and the second alignment hole 212a cooperate to position the frame 40 relative to the alignment structure 20, thereby improving the alignment accuracy of the frame 40 relative to the lens 10.

[0062] In some embodiments, the alignment member 41 includes a snap-fit ​​portion (not shown) that snaps into the second alignment hole 212a so that the frame 40 and the alignment structure 20 are snapped together by the alignment member 41.

[0063] Figure 9 for Figure 1 A schematic diagram of the alignment structure 20 in the illustrated embodiment; Figure 10 for Figure 1 A schematic diagram of the alignment structure 20 in the illustrated embodiment from another perspective; Figure 11 for Figure 1 A partial structural diagram of the alignment structure 20 and the lens 10 in the embodiment shown.

[0064] See Figures 9 to 11As described above, the alignment structure 20 provided in this embodiment includes a main body 21 and a mating part 22. The main body 21 includes a fitting part 211 and a protrusion 212. The fitting part 211 is used to fit against the inner side of the lens 10 along the thickness direction and is provided with a first alignment hole 211a. The first alignment hole 211a penetrates the fitting part 211 along the thickness direction of the lens 10 and is used to position the projector 30. The protrusion 212 protrudes beyond the outer contour of the lens 10. The mating part 22 protrudes from the side of the protrusion 212 close to the lens 10 along the thickness direction, and the shape of the mating part 22 is adapted to a portion of the outer periphery of the lens 10.

[0065] The aforementioned alignment structure 20 improves the alignment accuracy of the alignment structure 20 relative to the lens 10 by providing the mating part 22. Furthermore, by providing the first alignment hole 211a on the mating part 211, when the projector 30 is offset relative to the first alignment hole 211a, it will first contact the alignment part, preventing the projector 30 from directly engaging with the lens 10. Therefore, the projector 30 is allowed to re-align, reducing the probability of alignment failure when the projector 30 engages with the lens 10, reducing losses and thus lowering manufacturing costs.

[0066] In some embodiments, such as Figure 9 As shown, the protrusion 212 is provided with a second alignment hole 212a, which extends along the thickness direction of the lens 10 and is used to position the frame 40 to improve the alignment accuracy of the frame 40 relative to the lens 10.

[0067] In some embodiments, such as Figure 10 As shown, the bonding portion 211 includes a ring portion 2113 and an extension portion 2111. The ring portion 2113 defines a first alignment hole 211a, and the extension portion 2111 is connected to the outer periphery of the ring portion 2113. An adhesive layer (not shown) is provided between the extension portion 2111 and the lens 10. Thus, the alignment structure 20 is fixed relative to the lens 10 by the adhesive layer. By providing the extension portion 2111, the contact area between the adhesive layer and the bonding portion 211 and the lens 10 is increased, making the alignment structure 20 more reliably fixed relative to the lens 10. Optionally, the adhesive layer extends between the ring portion 2113 and the lens 10.

[0068] In some embodiments, such as Figure 10 As shown, the extension 2111 approaches the lens 10 along the thickness direction (see...). Figure 8 A groove 2111a is formed by recessing one side of the surface, and the adhesive layer is filled in the groove 2111a. In this way, by setting the groove 2111a, the thickness of the adhesive layer is increased, thereby further improving the fixing reliability of the alignment structure 20 and the lens 10.

[0069] In some embodiments, such as Figure 10As shown, there are two extensions 2111, which are arranged circumferentially along the ring 2113 to further improve the reliability of fixing the alignment structure 20 relative to the lens 10.

[0070] In some embodiments, such as Figure 11 As shown, the mating part 22 includes a middle part 222 and two side plates 221. Along the circumference of the lens 10, the middle part 222 is bent and connected between the two side plates 221. The middle part 222 protrudes from the ring part 2113 in the thickness direction, and the two side plates 221 respectively protrude from the extension parts 2111 in the thickness direction. This allows the mating part 22 to easily mate with the outer contour of the lens 10, and since the mating part 22 extends to the outside of the ring part 2113 and the two side plates 221 respectively, it helps to improve the alignment accuracy between the alignment structure 20 and the lens 10.

[0071] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
