Description

AR glasses, assembly method of AR glasses, and fixture equipment Technical Field

[0001] The present application relates to the field of display devices, and in particular to AR glasses, an assembly method for AR glasses, and a fixture device. Background Art

[0002] Existing AR (Augmented Reality) glasses products can provide users with many convenient functions. Among them, for users who need to correct their vision, in addition to setting up optical waveguides in the AR glasses to transmit the image output by the display component, matching refractive lenses are also required to assist users who need to correct their vision in using AR glasses.

[0003] Existing AR glasses and AR glasses assembly methods generally adopt the solution of gluing refractive lenses to optical waveguides. However, in reality, since each user's eye test data is different, when making AR glasses for users, it is necessary to first conduct an eye test for the user at an offline glasses store and trim and polish the refractive lenses according to the eye test data. The refractive lenses are then returned to the factory to be glued to the optical waveguide. Therefore, configuring AR glasses requires a long period of time, resulting in a poor user experience.

[0004] Furthermore, if the user finds that the refractive lens is not suitable after trying on the AR glasses, the bonding process is not conducive to adjusting or replacing the refractive lens, which greatly reduces the reworkability of the AR glasses.

Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.

[0042] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. The following embodiments and features in the embodiments may be combined with each other unless there is any conflict.

[0043] Please refer to Figures 1 to 3. Figure 1 is a module structure diagram of an embodiment of AR glasses provided in an embodiment of the present application, Figure 2 is a structural schematic diagram of an embodiment of AR glasses provided in an embodiment of the present application, and Figure 3 is a partial structural schematic diagram of an embodiment of AR glasses provided in an embodiment of the present application.

[0044] As shown in FIG1 to FIG3 , an embodiment of the present application provides an AR glasses 1 , including: a frame module 10 , a display module 20 and a refractive module 30 . The structures of each part of the AR glasses 1 are described in detail below.

[0045] Specifically, the frame module 10 includes a frame assembly 11 and a temple assembly 12 connected to the frame assembly 11. The frame assembly 11 is used to mount the display module 20 and the diopter module 30. The frame assembly 11 is provided with a first engaging structure 40, while the diopter module 30 is provided with a second engaging structure 50. The display module 20 includes a display assembly 21 and an optical waveguide assembly 22. The optical waveguide assembly 22 is connected to the frame assembly 11 and is provided with a light coupling region 221 and a light coupling region 222. The display assembly 21 is connected to the frame assembly 11 and is configured to correspond to the light coupling region 221.

[0046] It should be noted that the optical waveguide component 22 includes an optical waveguide lens, which forms the aforementioned light coupling region 221 and light coupling region 222. It is easy to understand that the optical waveguide component 22 is used to transfer the optical signal incident on the light coupling region 221 and emit it from the light coupling region 222.

[0047] Specifically, the second engaging structure 50 is configured to engage with the first engaging structure 40, and the diopter module 30 is disposed on the side of the optical waveguide assembly 22 close to the temple assembly 12, corresponding to the light outcoupling area 222. It should be understood that when the first engaging structure 40 of the frame assembly 11 engages with the second engaging structure 50 of the diopter module 30, the diopter module 30 is opposite to the light outcoupling area 222 and is located on the side of the optical waveguide assembly 22 close to the temple assembly 12.

[0048] It should be understood that under the action of external force, the first clamping structure 40 and the second clamping structure 50 can be engaged with each other, or the first clamping structure 40 and the second clamping structure 50 that are engaged with each other can be disengaged to achieve detachable cooperation between the refractive module 30 and the frame assembly 11.

[0049] For example, different users may have different vision correction needs, or multiple eye exams and polishing of the refractive module 30 may be required during the glasses fitting process. Or, after the refractive module 30 is installed, the user may still be dissatisfied with the refractive effect of the refractive module 30. In these scenarios, the AR glasses 1 provided in the embodiments of the present application improve the detachability of the refractive module 30 and facilitate repeated processing of the AR glasses 1.

[0050] Specifically, the AR glasses 1 provided in the embodiment of the present application are at least used to provide wearing support through the temple assembly 12. When the user wears the AR glasses 1, the temple assembly 12 is adapted to the user's head so that the AR glasses 1 are adapted to the user's face. Furthermore, the frame assembly 11 can also be used to provide wearing. Furthermore, the frame module 10 also includes a nose pad for providing wearing support.

[0051] As shown in FIG3 , the display component 21 is specifically configured to output an image. The image is incident on the light coupling region 221 of the optical waveguide component 22. The optical waveguide component 22 then transmits the image and emits it from the light coupling region 222. When a user wears the AR glasses 1, the user's head faces the light coupling region 222 of the optical waveguide component 22, and the image emitted from the light coupling region 222 is displayed in the user's field of view.

[0052] Exemplarily, the display component 21 is an optical machine for outputting image images.

[0053] Furthermore, the display module 20 also includes a control component 23, which is connected to the display component 21 to control the image output by the optical machine.

[0054] As shown in Figures 2 and 3, specifically, the refractive module 30 is used to adjust the light input to the refractive module 30 to meet the user's vision correction needs. For example, when the user has vision correction needs, the image picture output by the display component 21 is transmitted through the optical waveguide component 22 and input into the refractive module 30, while the light from the outside world directed toward the AR glasses 1 is transmitted through the optical waveguide component 22 and input into the refractive module 30. Then, the refractive module 30 adjusts the incident light signal so that the adjusted light signal reaches the user's field of view.

[0055] It should be understood that if there is no need for vision correction, the refractive module 30 can be replaced with a plano-optical module, and the light incident from the outside and the image output by the display component 21 are superimposed and pass through the plano-optical module into the user's field of view.

[0056] In some embodiments, the refractive module 30 includes at least a refractive lens.

[0057] In some embodiments, the refractive module 30 includes a refractive lens with one flat side and one concave side. If the refractive module 30 is used to solve the user's myopia correction needs, the flat side of the refractive lens faces the optical waveguide component 22, and the concave side of the refractive lens faces away from the optical waveguide component 22, so that the size of the AR glasses 1 in the thickness direction of the refractive module 30 can be further compressed, and it is convenient to control the distance between the refractive lens and the optical waveguide component 22 during the production process.

[0058] Please refer to FIG4 , which is a schematic structural diagram of an implementation of a refractive module of AR glasses provided in one embodiment of the present application.

[0059] As shown in Figures 3 and 4, in other embodiments, the refractive module 30 includes a refractive lens with one concave side and one convex side. If the refractive module 30 is used to solve the user's myopia correction needs, the convex side of the refractive lens faces the optical waveguide component 22, which is the same as the first direction, and the concave side of the refractive lens faces away from the optical waveguide component 22, which is opposite to the first direction.

[0060] Furthermore, the convex surface of the refractive lens is relatively flatter than the concave surface of the refractive lens, that is, the plane of the refractive lens facing the optical waveguide lens is a plane with a slight curvature.

[0061] Preferably, the curvature range R of the side of the refractive lens facing the light waveguide lens is greater than 130 mm, and the convex height range H is less than 2 mm.

[0062] In some embodiments, the optical waveguide assembly 22 includes an optical waveguide lens and protective members disposed on opposite sides of the optical waveguide lens. The protective members on either side are used to seal and protect the optical waveguide lens from both sides, thereby improving the durability of the optical waveguide lens. It should be noted that the opposite sides of the optical waveguide lens refer to the side of the optical waveguide lens close to the diopter module 30 (near-eye end) and the side of the optical waveguide lens away from the diopter module 30.

[0063] Preferably, the protective member is light-transmissive to ensure good overall light transmission performance of the optical waveguide assembly 22. Exemplarily, the protective member is glass, such as CG (Cover Glass).

[0064] In other embodiments, the optical waveguide assembly 22 includes an optical waveguide lens, and a protective member is only provided on the side of the optical waveguide lens away from the diopter module 30. That is, no protective member is provided on the side of the optical waveguide lens close to the diopter module 30.

[0065] It should be understood that the protective part has a certain thickness. Therefore, in the embodiment of the present application, the AR glasses 1 are not provided with a protective part on the side close to the refractive module 30, so that the dimensions of the optical waveguide component 22 and the refractive module 30 in the thickness direction are further compressed, making it lighter. In addition, the refractive module 30 and the first engaging mechanism 40 and the second engaging mechanism 50 that engage with each other are provided on the side of the optical waveguide lens close to the refractive module 30 (near-eye end), thereby ensuring the sealing and protection effect of the optical waveguide lens.

[0066] It should be understood that, as shown in Figures 2 and 3, Figure 2 is a schematic diagram of a partial structure of the AR glasses 1 provided in an embodiment of the present application. Preferably, the specific structure of the AR glasses 1 provided in an embodiment of the present application is as shown in Figure 3, having a bilateral structure for outputting and displaying image images on both sides of the AR glasses 1.

[0067] In some embodiments, the display component 21 includes at least a first display component 21 and a second display component 21, and the first display component 21 and the second display component 21 correspond to the left and right eyes of the user, respectively, and are used to output and display image images on both sides of the AR glasses 1.

[0068] It should be noted that, as shown in Figures 2 and 3, when the first locking structure 40 and the second locking structure 50 are locked and matched with each other, the refractive module 30 is installed in the frame assembly 11, and a certain distance is formed between the refractive module 30 and the optical waveguide assembly 22 to meet the optical design requirements. The locking and matching of the first locking structure 40 and the second locking structure 50 is also beneficial to prevent external dust, water vapor, etc. from entering the distance between the refractive module 30 and the optical waveguide assembly 22 and affecting the quality of the AR glasses 1.

[0069] Therefore, the AR glasses 1 provided in the embodiment of the present application realize reliable fixation of the refractive module 30 in the AR glasses 1 by setting a first snap-fit ​​structure 40 and a second snap-fit ​​structure 50 that snap-fit ​​with each other, thereby improving the detachability of the refractive module 30 and making the AR glasses 1 easy to repeat processing. In addition, the snap-fit ​​arrangement of the first snap-fit ​​structure 40 and the second snap-fit ​​structure 50 also isolates the space between the refractive module 30 and the optical waveguide component 22 from the outside world.

[0070] In some embodiments, at least one of the first snap-fit ​​structure 40 and the second snap-fit ​​structure 50 is an elastic snap-fit ​​structure, so that the refractive module 30 is snap-fitted and connected to the frame assembly 11, and is convenient for mutual installation and disassembly, and provides a certain redundancy for the design of the refractive module 30 in the length and width directions.

[0071] Please refer to Figure 5, which is a schematic diagram of a connection scenario of the first snap-fit ​​structure and the second snap-fit ​​structure in one implementation of the AR glasses provided in an embodiment of the present application.

[0072] As shown in Figure 5(a), in some embodiments, the first locking structure 40 includes a first connecting groove 41, which is arranged on the side of the frame assembly 11 facing the refractive module 30, and the second locking structure 50 includes a first elastic component 51, which is arranged on the side of the refractive module 30 and is used to form an elastic locking with the first connecting groove 41.

[0073] That is, at least the second engaging structure 50 is an elastic engaging structure.

[0074] Exemplarily, the first elastic component 51 includes an elastic rubber ring arranged on the side of the refractive module 30. When the first locking structure 40 and the second locking structure 50 are locked and matched, the elastic rubber ring is at least partially accommodated in the first connecting groove 41 and forms an engagement with the groove wall of the first connecting groove 41.

[0075] By disposing the first elastic component 51 on the side of the diopter module 30 , the installation and fixing effect of the diopter module 30 and the frame component 11 is improved, and the isolation effect of the interval between the diopter module 30 and the optical waveguide component 22 is improved.

[0076] For example, the elastic rubber ring is interference-fitted with the groove wall of the second connecting groove 52 , which further improves the installation and fixing effect of the refractive module 30 and the frame assembly 11 and the isolation effect of the space between the refractive module 30 and the optical waveguide assembly 22 .

[0077] As shown in FIG5(b), in some embodiments, a first elastic adhesive layer 43 is provided on the inner wall of the first connecting groove 41 to enhance the installation and fixing effect of the refractive module 30 and the frame assembly 11, and to reserve a certain redundancy for the design of the refractive module 30 in the length and width directions.

[0078] As shown in FIG. 5( a ) and FIG. 5 ( b ), in some embodiments, the refractive module 30 is provided with a first receiving groove 31 , and the first elastic component 51 is detachably connected to the refractive module 30 via the first receiving groove 31 .

[0079] Specifically, the first elastic component 51 can be accommodated in the first receiving groove 31 or detached from the first receiving groove 31 to achieve a detachable connection between the first elastic component 51 and the refractive module 30 .

[0080] In some embodiments, the first receiving groove 31 is arranged relative to the frame assembly 11 and formed on the side of the refractive module 30. When the first elastic component 51 is connected and adapted to the refractive module 30, the first elastic component 51 partially protrudes from the first receiving groove 31.

[0081] It should be noted that when the first elastic component 51 is detachably connected to the diopter module 30 , a portion of the first elastic component 51 is received in the first receiving groove 31 , while another portion is exposed from the first receiving groove 31 and protrudes from the side of the diopter module 30 .

[0082] Please refer to Figure 6, which is a schematic structural diagram of the first elastic component in one implementation of the AR glasses provided in an embodiment of the present application.

[0083] As shown in FIG. 6( a ), in some embodiments, at least two first elastic components 51 are provided, and the first elastic components 51 and the first connecting groove 41 form at least a two-point elastic structure engagement.

[0084] Specifically, at least two first elastic components 51 are provided in the AR glasses 1 , and the first connecting grooves 41 are provided corresponding to the first elastic components 51 and respectively form elastic structural engagement with the at least two first elastic components 51 .

[0085] Exemplarily, at least two first connecting grooves 41 are formed on the side of the frame assembly 11 near the refractive module 30, and the number and position of the first connecting grooves 41 correspond to the first elastic components 51. When the first snap-fit ​​structure 40 and the second snap-fit ​​structure 50 are snap-fitted, each first elastic component 51 is snap-fitted and connected to the corresponding first connecting groove 41.

[0086] Correspondingly, a first receiving groove 31 is formed on the side of the diopter module 30 at a position opposite the first elastic component 51. In some embodiments, at least two first receiving grooves 31 are provided, and the positions of the first receiving grooves 31 correspond to the diopter module 30 to receive each first elastic component 51.

[0087] In some embodiments, the first elastic components 51 are disposed at least on two opposite sides of at least one of the length direction and the width direction of the refractive module 30 .

[0088] Specifically, the first elastic components 51 are disposed on at least two opposite sides of at least one of the length and width directions of the refractive module 30, so that the frame assembly 11 can engage the refractive module 30 evenly, thereby improving the installation and fixation of the refractive module 30 to the frame assembly 11. For example, when the first elastic components 51 are disposed on two opposite sides of the length of the refractive module 30, the refractive module 30 can be evenly engaged and fixed from both opposite sides of the length of the refractive module 30.

[0089] Similarly, when the first elastic component 51 is arranged on opposite sides of the width direction of the refractive module 30, or when the first elastic component 51 is arranged on opposite sides of the width direction and opposite sides of the length direction of the refractive module 30, the snapping effect of the frame component 11 on the refractive module 30 can also be uniform, thereby improving the installation and fixing effect of the refractive module 30 and the frame component 11.

[0090] For example, as shown in FIG. 6( a ), the first elastic components 51 are disposed on opposite sides of the diopter module 30 in both the length direction and the width direction, thereby making the engagement and fixation of the diopter module 30 more uniform.

[0091] As shown in FIG. 6( b ), in some embodiments, the first elastic component 51 includes a first elastic ring 511 sleeved on the outer circumference of the refractive module 30 .

[0092] Specifically, the first elastic component 51 is arranged on the outer peripheral side of the refractive module 30, and the first elastic component 51 cooperates with the frame component 11 to engage and fix the refractive module 30 from the circumferential direction, so that the engaging effect of the frame component 11 on the refractive module 30 is uniform, thereby improving the installation and fixing effect of the refractive module 30 and the frame component 11.

[0093] For example, the first elastic ring 511 is a rubber ring, and the cross-sectional shape of the rubber ring can be square, circular, polygonal, etc., which is not specifically limited here.

[0094] As shown in Figure 6(b), in some embodiments, the refractive module 30 also includes an avoidance position 32 formed in the first connecting groove 41 and used to adapt to an external workpiece. When the first elastic component 51 is connected to the first receiving groove 31, the first elastic component 51 is wrapped in the avoidance position 32.

[0095] Specifically, the external workpiece is, for example, the fixture device 2. When the first elastic component 51 is connected to the first receiving groove 31, the first elastic component 51 is wrapped around the avoidance position 32. When the fixture device 2 is clamped on the outer peripheral side of the first elastic component 51, and the clamping position is opposite to the avoidance position 32, the portion of the first elastic component 51 located between the fixture device 2 and the avoidance position 32 is displaced in the recessed direction of the avoidance position 32 and undergoes a certain elastic deformation. This reduces the space required by the fixture device 2 in the radial direction of the refractive module 30 when clamping the refractive module 30 and the first elastic component 51. This facilitates installation of the refractive module 30 and the first elastic component 51 to corresponding positions on the frame assembly 11 when assembling the AR glasses 1.

[0096] Furthermore, after the refractive module 30 and the first elastic component 51 are installed to the corresponding positions on the frame component 11, the clamping device 2 is detached from the refractive module 30, and the deformation and displacement of the first elastic component 51 are restored so that the first elastic component 51 is adapted to the first connecting groove 41 and the first receiving groove 31.

[0097] Please refer to FIG. 7 , which is a schematic structural diagram of a first engaging structure and a second engaging structure in another implementation of the AR glasses provided in an embodiment of the present application.

[0098] As shown in Figure 7(a), in some embodiments, the second locking structure 50 includes a second connecting groove 52, which is arranged on the side of the refractive module 30 facing the frame assembly 11, and the first locking structure 40 includes a second elastic component 42, which is arranged on the side of the frame assembly 11 and is used to form an elastic locking with the second connecting groove 52.

[0099] That is, at least the first engaging structure 40 is an elastic engaging structure.

[0100] Exemplarily, the second elastic component 42 includes an elastic rubber ring arranged on the inner circumference of the frame component 11. When the first locking structure 40 and the second locking structure 50 are locked and matched, the elastic rubber ring is at least partially accommodated in the second connecting groove 52 and forms an engagement with the groove wall of the second connecting groove 52.

[0101] By disposing the second elastic component 42 on the inner circumference of the frame component 11 , the installation and fixing effect of the refractive module 30 and the frame component 11 is improved, and the isolation effect of the interval between the refractive module 30 and the optical waveguide component 22 is improved.

[0102] For example, the elastic rubber ring is interference-fitted with the groove wall of the second connecting groove 52 , which further improves the installation and fixing effect of the refractive module 30 and the frame assembly 11 and the isolation effect of the space between the refractive module 30 and the optical waveguide assembly 22 .

[0103] As shown in FIG. 7( b ), in some embodiments, a second elastic adhesive layer 53 is provided on the inner wall of the second connecting groove 52 to enhance the installation and fixing effect of the refractive module 30 and the frame assembly 11 , and to reserve a certain redundancy for the design of the refractive module 30 in the length and width directions.

[0104] As shown in FIG. 7 ( a ) and ( b ), in some embodiments, the frame assembly 11 is provided with a second receiving groove 113 , and the second elastic assembly 42 is detachably connected to the frame assembly 11 via the second receiving groove 113 .

[0105] Specifically, the second elastic component 42 can be received in the second receiving groove 113 or detached from the second receiving groove 113 to achieve a detachable connection between the second elastic component 42 and the frame assembly 11. When the second elastic component 42 is detachably connected to the frame assembly 11, a portion of the second elastic component 42 is received in the second receiving groove 113, while another portion is exposed from the second receiving groove 113 and protrudes from the inner circumference of the frame assembly 11.

[0106] As shown in FIG. 3 and FIG. 5 , in some embodiments, the spacing between the refractive module 30 and the optical waveguide component 22 in the first direction is 1–100 μm, wherein the first direction is the direction of the temple component 12 relative to the frame component 11 .

[0107] It should be noted that if the spacing between the refractive module 30 and the optical waveguide component 22 in the first direction is less than 1 μm, the submicron-level spacing may cause diffraction fringes in the visible light band. Conversely, if the gap is greater than 100 μm, the tight fit between the refractive module 30 and the optical waveguide component 22 in the first direction is poor, resulting in a larger volume of the AR glasses 1.

[0108] In this embodiment of the present application, a first engaging structure 40 and a second engaging structure 50 are provided to engage and mount the diopter module 30 to the frame assembly 11. This ensures that the spacing between the diopter module 30 and the optical waveguide assembly 22 in the first direction is relatively fixed after installation, and limits the spacing between the diopter module 30 and the optical waveguide assembly 22 in the first direction to a range of 1–100 μm. Compared to existing solutions for securing the diopter module 30, such as magnetic or adhesive solutions, the thickness of the diopter module 30 and the optical waveguide assembly 22 in the first direction is further effectively reduced, making the AR glasses 1 more lightweight.

[0109] In some embodiments, a guide groove 114 for adapting to an external workpiece is provided on the side of the frame assembly 11 close to the refractive module 30, wherein the width of the guide groove 114 close to the temple assembly 12 is greater than the width of the side away from the temple assembly 12.

[0110] 15 to 16 , the external workpiece is, for example, a fixture device 2. Since the width of the guide groove 114 on the side close to the temple assembly 12 is greater than the width on the side away from the temple assembly 12, when the fixture device 2 clamps and transfers the refractive module 30 to install the refractive module 30 in the frame assembly 11, the refractive module 30 is more easily moved to the installation position matched with the refractive module 30 under the guidance of the guide groove 114, thereby reducing the difficulty of installation and reducing installation errors.

[0111] As shown in Figures 1 to 7, in some embodiments, the frame assembly 11 includes a lens mounting member 111 and a temple connector 112 connected to the temple assembly 12 and the lens mounting member 111, and the lens mounting member 111 is provided with a first snap-fit ​​structure 40 to connect to the refractive module 30, wherein the optical waveguide assembly 22 is connected to the side of the lens mounting member 111 away from the temple connector 112.

[0112] Specifically, the first engaging structure 40 is provided on the lens mounting member 111, and the optical waveguide assembly 22 is connected to the side of the lens mounting member 111 away from the temple connecting member 112. It should be understood that the image output by the display assembly 21 is transmitted by the optical waveguide assembly 22 and is incident on the refractive module 30, while the light from the outside world directed toward the AR glasses 1 is transmitted through the optical waveguide assembly 22 and is incident on the refractive module 30. The refractive module 30 then adjusts the incident light signal so that the adjusted light signal reaches the user's field of view. Therefore, when the user wears the AR glasses 1, the light from the outside world directed toward the AR glasses 1 and the image output by the display assembly 21 are transmitted by the optical waveguide assembly 22 and enter the user's field of view together.

[0113] Please refer to Figure 8, which is a schematic diagram of the accommodating cavity in one implementation of the AR glasses provided in an embodiment of the present application.

[0114] As shown in Figure 8, in some embodiments, the frame assembly 11 further includes a accommodating cavity 60, which is arranged on a side of the lens mounting member 111 close to the temple assembly 12 and opposite to the light coupling area 221 of the optical waveguide assembly 22, and the display assembly 21 is accommodated in the accommodating cavity 60.

[0115] It should be noted that at least one of the lens mounting member 111 and the temple connecting member 112 forms the accommodating cavity 60. For example, in FIG8 , the accommodating cavity 60 is formed on the side of the lens mounting member 111 adjacent to the temple connecting member 112. Specifically, the accommodating cavity 60 is opposite to the light coupling-in region 221 of the optical waveguide assembly 22 and is used to accommodate the display assembly 21 so that the image output by the display assembly 21 can accurately enter the light coupling-in region 221 of the optical waveguide assembly 22.

[0116] As shown in Figures 1 to 8, in some embodiments, the lens mounting member 111 includes a central portion 1111, the first snap-fit ​​structure 40 is disposed on a side of the central portion 1111 close to the temple assembly 12, and the optical waveguide assembly 22 is connected to a side of the central portion 1111 away from the temple assembly 12.

[0117] That is, the side of the lens mounting member 111 close to the first engaging structure 40 and the optical waveguide assembly 22 is in a “T-shaped structure”: the first engaging structure 40 and the optical waveguide assembly 22 are separated on both sides of the “T-shaped structure”.

[0118] It should be understood that the central portion 1111 separates the first engaging structure 40 from the optical waveguide component 22 to ensure the distance between the refractive module 30 and the optical waveguide component 22 , while also improving the overall strength of the AR glasses 1 .

[0119] Please refer to Figures 9 and 10. Figure 9 is a module structure diagram of another implementation of the AR glasses provided in one embodiment of the present application, and Figure 10 is a structural schematic diagram of another implementation of the AR glasses provided in one embodiment of the present application.

[0120] As shown in Figures 9 and 10, the embodiment of the present application also provides another AR glasses 1, including: a frame assembly 11, a display module 20 and a refractive module 30, wherein the frame assembly 11 is provided with a first locking structure 40 and a temple connector 112 for adapting to the external temple; the display module 20 includes a display assembly 21 and an optical waveguide assembly 22, the optical waveguide assembly 22 is connected to the frame assembly 11, and the optical waveguide assembly 22 is provided with a light coupling-in area 221 and a light coupling-out area 222, the display assembly 21 is connected to the frame assembly 11 and is arranged corresponding to the light coupling-in area 221; the refractive module 30 is provided with a second locking structure 50, the second locking structure 50 is configured to be locked and matched with the first locking structure 40, and the refractive module 30 is arranged on the side of the optical waveguide assembly 22 close to the temple connector 112 corresponding to the light coupling-out area 222.

[0121] It should be understood that the other AR glasses 1 provided in the embodiment of the present application are provided with temple connectors 112, and are used to adapt and connect with external temples through the temple connectors 112. It should be noted that the structure and principle of each part of the other AR glasses 1 provided in the embodiment of the present application can be referred to the above description and will not be repeated here.

[0122] Please refer to FIG11 , which is a flowchart illustrating the steps of an AR glasses assembly method provided in one embodiment of the present application.

[0123] As shown in FIG11 , the embodiment of the present application further provides an assembly method for AR glasses 1, which is at least used to assemble and generate any one of the AR glasses 1 provided in the embodiment of the present application. The assembly method for AR glasses 1 specifically includes steps S1 to S3:

[0124] Step S1: providing a frame assembly 11, a diopter module 30 to be mounted on the frame assembly 11, and a fixture device 2 for clamping the diopter module 30;

[0125] Step S2: Control the clamping device 2 to clamp the diopter module 30 and transfer the diopter module 30 so that the second engaging structure 50 of the diopter module 30 is engaged with the first engaging structure 40 of the frame assembly 11 ;

[0126] Step S3: Remove the fixture device 2 to obtain the AR glasses 1.

[0127] Please refer to Figures 12 and 14. Figure 12 is a schematic diagram of transferring the first elastic component to the first connecting groove in the AR glasses assembly method provided in an embodiment of the present application. Figure 13 is a structural schematic diagram of a clamp device provided in an embodiment of the present application. Figure 14 is a schematic diagram of using a clamp device to transfer the refractive module in an implementation method of the AR glasses assembly method provided in an embodiment of the present application.

[0128] As shown in Figures 1 to 12, in some embodiments, the first engaging structure 40 includes a first connecting groove 41, which is disposed on a side of the frame assembly 11 facing the diopter module 30. The second engaging structure 50 includes a first receiving groove 31 and a first elastic component 51. The first receiving groove 31 is disposed relative to the frame assembly 11 and formed lateral to the diopter module 30. When the first elastic component 51 is connected and adapted to the diopter module 30, a portion of the first elastic component 51 protrudes from the first receiving groove 31.

[0129] Accordingly, in step S2, controlling the fixture device 2 to clamp the refractive module 30 and transfer the refractive module 30 includes:

[0130] Providing a first elastic component 51;

[0131] Transfer the first elastic component 51 to the first receiving groove 31 so that a portion of the first elastic component 51 protrudes from the side of the diopter module 30 ;

[0132] Controlling the clamping device 2 to clamp the refractive module 30 from the outside of the refractive module 30 ;

[0133] The refractive module 30 and the first elastic component 51 are transferred by the clamping device 2 so that the first elastic component 51 is accommodated in the first connecting groove 41 and the first receiving groove 31 .

[0134] Specifically, the provided first elastic component 51 is first installed and adapted to the refractive module 30, and the installation and adaptation of the first elastic component 51 to the refractive module 30 specifically includes: transferring the first elastic component 51 to the first connecting groove 41 so that the first elastic component 51 is partially protruded from the side of the refractive module 30.

[0135] It should be noted that FIG12( a ) is a schematic diagram before the first elastic component 51 is transferred to the first connecting groove 41 , and FIG12( b ) is a schematic diagram after the first elastic component 51 is transferred to the first receiving groove 31 .

[0136] It should be noted that the transfer of the first elastic component 51 to the first receiving groove 31 can be performed by a device or by an operator, and this embodiment of the present application does not specifically limit this.

[0137] As shown in Figures 12 and 13, after the first elastic component 51 and the refractive module 30 are installed and adapted, the clamping device 2 is controlled to clamp the refractive module 30 from the outer peripheral side of the refractive module 30, and the refractive module 30 and the first elastic component 51 are transferred through the clamping device 2 so that the first elastic component 51 is accommodated in the first connecting groove 41 and the first receiving groove 31.

[0138] As shown in Figure 13, in some embodiments, when the clamping device 2 is clamped on the outer peripheral side of the first elastic component 51, the clamping device 2 pushes the first elastic component 51 toward the recessed direction of the first receiving groove 31, so as to cause at least the portion of the first elastic component 51 located between the clamping device 2 and the first receiving groove 31 to be displaced and / or compressed.

[0139] Please refer to FIG. 14 , which is a schematic diagram of transferring the refractive module in another embodiment of the AR glasses assembly method provided in an embodiment of the present application.

[0140] As shown in FIG2 to FIG3 and FIG14, in some embodiments, the assembly method of the AR glasses 1 provided in the embodiment of the present application further includes:

[0141] Controlling the clamping device 2 to clamp the refractive module 30 from the outside of the refractive module 30 so that the first elastic component 51 is compressed toward the first connecting groove 41;

[0142] After the clamping device 2 is separated from the refractive module 30 , the deformation of the first elastic component 51 is restored, so that the first elastic component 51 is adapted to the first connecting groove 41 and the first receiving groove 31 .

[0143] Specifically, when the clamping device 2 is clamped on the outer peripheral side of the first elastic component 51, the clamping device 2 pushes the first elastic component 51 toward the recessed direction of the first receiving groove 31, and the part of the first elastic component 51 located between the clamping device 2 and the first receiving groove 31 is displaced and / or compressed. After the clamping device 2 is separated from the refractive module 30, the deformation of the first elastic component 51 is restored so that the first elastic component 51 is adapted to the first connecting groove 41 and the first receiving groove 31.

[0144] Among them, Figures 2 to 3 can be regarded as schematic diagrams of the deformation recovery of the first elastic component 51 after the clamp device 2 is separated from the refractive module 30. It can be seen that a part of the first elastic component 51 is adapted to the first connecting groove 41, and a part of the first elastic component 51 is adapted to the first receiving groove 31. Thus, the installation of the refractive module 30 and the frame assembly 11 is fixed, and the design of the first elastic component 51 improves the isolation effect of the interval between the refractive module 30 and the optical waveguide assembly 22.

[0145] It should also be noted that when the clamping device 2 clamps the refractive module 30 and the first elastic component 51, the elastic design of the first elastic component 51 is used to reduce the space required by the clamping device 2 in the radial direction of the refractive module 30, making it easier to move the refractive module 30 and the first elastic component 51 to the corresponding positions on the frame assembly 11.

[0146] As shown in FIG6( b ), FIG12 and FIG13 , in some embodiments, the refractive module 30 further includes an avoidance position 32 formed in the first connecting groove 41 and adapted to be adapted to the clamp device 2 . When the first elastic component 51 is transferred to the first connecting groove 41 , the first elastic component 51 is disposed in the avoidance position 32 .

[0147] Controlling the clamping device 2 to clamp the refractive module 30 from the outside of the refractive module 30 includes:

[0148] The clamping device 2 is controlled to clamp toward the avoidance position 32 , so that at least a portion of the first elastic component 51 located in the first connecting groove 41 is displaced toward the recessed direction of the avoidance position 32 .

[0149] Specifically, the clamping device 2 includes at least two clamping members 201. When the clamping members 201 cooperate to push in the relative direction of the refractive module 30, the clamping device 2 can clamp the refractive module 30 and the first elastic component 51. In the process of controlling the clamping device 2 to clamp the refractive module 30 from the outside of the refractive module 30, at least one clamping member 201 in the clamping device is controlled to push in the direction of the avoidance position 32, so that at least a portion of the first elastic component 51 located in the first connecting groove 41 is compressed or displaced in the concave direction of the avoidance position 32. As a result, when the clamping device 2 clamps the refractive module 30 and the first elastic component 51, the space required by the clamping device 2 in the radial direction of the refractive module 30 is reduced, which facilitates the installation of the refractive module 30 and the first elastic component 51 to the corresponding positions on the frame assembly 11 when assembling the AR glasses 1.

[0150] After controlling the clamping device 2 to clamp the refractive module 30 from the outside of the refractive module 30, the refractive module 30 and the first elastic component 51 are transferred by the clamping device 2 so that the first elastic component 51 is accommodated in the first connecting groove 41 and the first receiving groove 31, and the clamping device 2 is removed to install and fix the refractive module 30 and the frame component 11.

[0151] Please refer to FIG. 15 , which is a schematic diagram of transferring the refractive module and the first elastic component in one embodiment of the AR glasses assembly method provided in an embodiment of the present application.

[0152] As shown in FIG. 15 , in some embodiments, the step S2 of transferring the refractive module 30 and the first elastic component 51 by the fixture device 2 includes:

[0153] Control the fixture device 2 to move the diopter module 30 to a side of the frame assembly 11 away from the optical waveguide assembly 22;

[0154] The predetermined pressing tool 3 is used to push the refractive module 30 clamped in the clamping device 2 toward the direction of the frame assembly 11 so that the first elastic component 51 is opposite to the first connecting groove 41 .

[0155] Specifically, as shown in Figure 15(a), the clamping device 2 is first controlled to move the refractive module 30 to the side of the frame assembly 11 away from the optical waveguide assembly 22, and then as shown in Figure 15(b), a preset pressing tool 3 is used to provide pressure to the refractive module 30, and the direction of the pressure is the direction of the refractive module 30 toward the frame assembly 11, thereby pushing the refractive module 30 clamped in the clamping device 2 to move toward the frame assembly 11, so that the first elastic component 51 is opposite to the first connecting groove 41. For details, please refer to the positional relationship between the first elastic component 51 and the first connecting groove 41 as shown in Figure 15(c).

[0156] In some embodiments, controlling the clamping device 2 to clamp the refractive module 30 from the outside of the refractive module 30 includes: controlling the clamping device 2 to clamp the refractive module 30 from the side of the refractive module 30 with the rear end of the clamping device 2;

[0157] Controlling the clamping device 2 to move the diopter module 30 to the side of the frame assembly 11 away from the optical waveguide assembly 22 includes: controlling the clamping device 2 to move so that the front end of the clamping device 2 abuts against the frame assembly 11 .

[0158] Specifically, in this embodiment, the rear end of the clamp device 2 is first used to clamp the refractive module 30 from the side of the refractive module 30, and then the clamp device 2 is controlled to move so that the front end of the clamp device 2 is in contact with the frame assembly 11, and then the preset pressing tool 3 is used to push the refractive module 30 clamped in the clamp device 2 toward the direction of the frame assembly 11, so that the first elastic component 51 is opposite to the first connecting groove 41, which is convenient for aligning the refractive module 30 with the frame assembly 11 when assembling the AR glasses 1, thereby reducing the precision requirement of the moving clamp device 2.

[0159] As shown in Figures 13 and 14, the clamping device 2 includes at least two clamping members 201, and the clamping member 201 specifically includes a first clamping portion 2011 and a second clamping portion 2012 that are relatively arranged, wherein the first clamping portion 2011 is arranged at the front end of the clamping member 201, and the second clamping portion 2012 is arranged at the rear end of the clamping member 201, then the clamping device 2 is controlled to clamp the refractive module 30 from the side of the refractive module 30 with the second clamping portion 2012, and then the clamping device 2 is controlled to move so that the first clamping portion 2011 of the clamping device 2 is abutted against the frame assembly 11, and a preset pressing tool 3 is used to push the refractive module 30 clamped in the clamping device 2 toward the direction of the frame assembly 11, so that the first elastic component 51 is opposite to the first connecting groove 41, thereby accurately sending the refractive module 30 and the first elastic component 51 to the corresponding installation positions.

[0160] As shown in Figures 12 and 13, in some embodiments, the clamping device 2 includes at least two clamping members 201 for cooperating in clamping the refractive module 30, and the clamping member 201 includes a first clamping portion 2011 located at the front end of the clamping member 201 and a second clamping portion 2012 located at the rear end of the clamping member 201, wherein the thickness of the second clamping portion 2012 in the second direction is less than the thickness of the first clamping portion 2011, and the second direction is opposite to the direction in which the clamping member 201 clamps the refractive module 30.

[0161] Specifically, the second direction is opposite to the direction in which the clamping member 201 clamps the refractive module 30 (as shown in Figure 13), and the thickness of the second clamping portion 2012 in the second direction is less than the thickness of the first clamping portion 2011. Therefore, when the control clamping device 2 clamps the refractive module 30 from the side of the refractive module 30 with the second clamping portion 2012, the second clamping portion 2012 with a thicker thickness clamps the refractive module 30 more firmly, and when the control clamping device 2 moves, the clamping device 2 is more easily transferred to abut against the frame assembly 11 under the guidance of the first clamping portion 2011.

[0162] As shown in FIG1 to FIG13 , it should be noted that the flowchart of the assembly method of the AR glasses 1 shown in FIG11 only includes the process of installing the refractive module 30 on the frame module 10. In some embodiments, before installing the refractive module 30 on the frame module 10, the following steps are also included:

[0163] The display component 21 and / or the optical waveguide component 22 are mounted on the mirror frame module 10 .

[0164] 2 to 5 are schematic diagrams of the structure of the display assembly 21 and the optical waveguide assembly 22 mounted on the frame module 10. For example, the display assembly 21 and / or the optical waveguide assembly 22 are mounted and fixed to the frame module 10 by gluing.

[0165] It should be noted that in the assembly method of the AR glasses 1 provided in the embodiment of the present application, during the assembly process of the AR glasses 1, the display component 21 and the optical waveguide component 22 are first fixedly installed on the frame component 11, and then the refractive module 30 is installed on the frame component 11 through the detachable first snap-fit ​​structure 40 and the second snap-fit ​​structure 50. Among them, the installation of the refractive module 30 is simpler and more cost-effective. After the display component 21 and the optical waveguide component 22 are installed, the refractive module 30 can be repeatedly trimmed or replaced.

[0166] For example, different users may have different vision correction needs, or multiple eye exams and polishing of the refractive module 30 may be required during the glasses fitting process. Or, after the refractive module 30 is installed, the user may still be dissatisfied with the refractive effect of the refractive module 30. In these scenarios, the assembly method of the AR glasses 1 provided in the embodiments of the present application improves the detachability of the refractive module 30 and facilitates repeated processing of the AR glasses 1.

[0167] In some embodiments, before controlling the clamping device 2 to clamp the refractive module 30 and transfer the refractive module 30 , the method further includes:

[0168] Transferring the optical waveguide assembly 22 from the opposite direction of the first direction to the mirror frame assembly 11;

[0169] The control fixture device 2 is used to clamp the refractive module 10 and transfer the refractive module 10 from a first direction to the frame assembly 11 . The first direction is the direction of the temple assembly 12 relative to the frame assembly 11 .

[0170] It should be understood that in the embodiment of the present application, the optical waveguide assembly 22 and the diopter module 30 are installed in opposite directions. Specifically, as shown in Figures 1 to 8, the lens mounting member 111 includes a central portion 1111, the first engaging structure 40 is disposed on a side of the central portion 1111 close to the temple assembly 12, and the optical waveguide assembly 22 is connected to a side of the central portion 1111 away from the temple assembly 12. It is easy to understand that the central portion 1111 separates the first engaging structure 40 from the optical waveguide assembly 22 to ensure the distance between the diopter module 30 and the optical waveguide assembly 22, while also improving the overall strength of the AR glasses 1.

[0171] As shown in Figures 13 and 14, an embodiment of the present application also provides a clamping device 2, which is used to assemble and generate any one of the AR glasses 1 provided in the embodiment of the present application. The clamping device 2 includes at least two clamping members 201 for clamping the target lens. The clamping member 201 includes a first clamping portion 2011 located at the front end of the clamping member 201 and a second clamping portion 2012 located at the rear end of the clamping member 201, wherein the thickness of the second clamping portion 2012 in the second direction is less than the thickness of the first clamping portion 2011, and the second direction is opposite to the direction in which the clamping member 201 clamps the refractive module 30.

[0172] Specifically, the second direction is opposite to the direction in which the clamping member 201 clamps the refractive module 30 (as shown in Figure 13), and the thickness of the second clamping portion 2012 in the second direction is less than the thickness of the first clamping portion 2011. Therefore, when the control clamping device 2 clamps the refractive module 30 from the side of the refractive module 30 with the second clamping portion 2012, the second clamping portion 2012 with a thicker thickness clamps the refractive module 30 more firmly, and when the control clamping device 2 moves, the clamping device 2 is more easily transferred to abut against the frame assembly 11 under the guidance of the first clamping portion 2011.

[0173] In some embodiments, the thickness of the second clamping portion 2012 in the second direction is 0.02-0.4 mm.

[0174] Specifically, the thickness of the second clamping portion 2012 in the second direction is less than the thickness of the first clamping portion 2011. The thickness of the second clamping portion 2012 in the second direction is 0.02 to 0.4 mm, so that when controlling the movement of the clamping device 2, the clamping device 2 can be more easily transferred to abut against the frame assembly 11 under the guidance of the first clamping portion 2011.

[0175] Please refer to FIG. 16 , which is a schematic diagram of an AR glasses transfer refractive module 30 and a first elastic component provided in an embodiment of the present application.

[0176] As shown in FIG. 16 , in some embodiments, at least one second clamping portion 2012 is a flexible member.

[0177] It should be noted that, by designing at least one second clamping portion 2012 as a flexible part, even if the refractive module 30 cannot be aligned with the corresponding installation position during the process of the clamp device 2 transferring the refractive module 30 as shown in Figure 16(a), when the refractive module 30 is pushed toward the frame assembly 11, the flexible second clamping portion 2012 can still guide the refractive module 30 to the corresponding installation position. Figure 16(b) is a specific illustration of the second clamping portion 2012 pushing the refractive module 30 to the installation position.
