Abstract
Description
AR glasses, assembly method of AR glasses and fixture device TECHNICAL FIELD
[0001] The present application relates to the field of display devices, in particular to an AR glasses, an assembly method of AR glasses and a fixture device. BACKGROUND
[0002] The existing AR (Augmented Reality) glasses products can provide many convenient functions for users. For users who need to correct their vision, in addition to setting a light waveguide in the AR glasses to transmit the image picture output by the display component, a matching dioptric lens also needs to be set to assist users who need to correct their vision to use the AR glasses.
[0003] The existing AR glasses and the assembly method of AR glasses generally adopt the scheme of gluing the dioptric lens to the light waveguide. However, in fact, since the refraction data of each user is different, when manufacturing AR glasses for a user, the user needs to be refracted in an offline glasses store first, and the edge of the dioptric lens is cut and polished according to the refraction data, and then the dioptric lens is glued to the light waveguide at the factory end. Therefore, it takes a long period of time to configure the AR glasses, which causes poor user experience.
[0004] In addition, if the user finds that the dioptric lens is not suitable after trying on the AR glasses, the gluing process is not conducive to adjusting or replacing the dioptric lens, which greatly reduces the reworkability of the AR glasses.

Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
[0044] Some embodiments of the present application will be described in detail below in combination with the drawings, and the following embodiments and features in the embodiments can be combined with each other without conflict.
[0045] Please refer to FIG. 1 to FIG. 3, FIG. 1 is a module structure diagram of an embodiment of AR glasses provided by the present application, FIG. 2 is a structure schematic diagram of an embodiment of AR glasses provided by the present application, and FIG. 3 is a partial structure schematic diagram of an embodiment of AR glasses provided by the present application.
[0046] As shown in FIGS. 1-3, the AR glasses 1 provided by the embodiments of the present application include a frame module 10, a display module 20, and a near-eye lens module 30. The structures of the AR glasses 1 are described in detail as follows.
[0047] 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 configured to mount the display module 20 and the near-eye lens module 30. The frame assembly 11 is provided with a first clamping structure 40, and the near-eye lens module 30 is provided with a second clamping 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 coupling-in grating area 221 and a coupling-out grating area 222. The display assembly 21 is connected to the frame assembly 11 and is arranged corresponding to the coupling-in grating area 221.
[0048] It should be noted that the optical waveguide assembly 22 includes an optical waveguide lens, which forms the coupling-in grating area 221 and the coupling-out grating area 222. It is known that the optical waveguide assembly 22 is configured to transfer the light signal entering the coupling-in grating area 221 and emit the light signal from the coupling-out grating area 222.
[0049] Specifically, the second clamping structure 50 is configured to be clamped and matched with the first clamping structure 40, and the near-eye lens module 30 is arranged on the side of the optical waveguide assembly 22 close to the temple assembly 12 corresponding to the coupling-out grating area 222. It should be understood that when the first clamping structure 40 of the frame assembly 11 is clamped and matched with the second clamping structure 50 of the near-eye lens module 30, the near-eye lens module 30 is opposite to the coupling-out grating area 222 and is arranged on the side of the optical waveguide assembly 22 close to the temple assembly 12.
[0050] It should be understood that under the action of an external force, the first clamping structure 40 and the second clamping structure 50 can be clamped with each other, and the first clamping structure 40 and the second clamping structure 50 clamped with each other can be separated, so as to realize the detachable cooperation between the near-eye lens module 30 and the frame assembly 11.
[0051] For example, different users may have different vision correction needs, or multiple refractions and polishing of the near-eye lens module 30 are required in the process of selecting glasses for the user, or the user is still not satisfied with the refractive effect of the near-eye lens module 30 after the near-eye lens module 30 is installed. In these scenarios, the AR glasses 1 provided by the embodiments of the present application improve the detachability of the near-eye lens module 30 and facilitate repeated processing of the AR glasses 1.
[0052] Specifically, the AR glasses 1 provided by the embodiments of the present application are used to provide wearing support at least through the temple assembly 12. When a user wears the AR glasses 1, the temple assembly 12 is adapted to the head of the user to make the AR glasses 1 adapt to the face of the user. Further, the frame assembly 11 can also be used to provide wearing. Further, the frame assembly 10 further includes a nose pad used to provide wearing support.
[0053] As shown in FIG. 3, specifically, the display assembly 21 is used to output an image picture. The image picture is incident to the coupling-in grating area 221 of the optical waveguide assembly 22. The optical waveguide assembly 22 transmits the image picture and emits the image picture from the coupling-out grating area 222. When the user wears the AR glasses 1, the head of the user is opposite to the coupling-out grating area 222 of the optical waveguide assembly 22. The image picture emitted from the coupling-out grating area 222 is displayed in the visual field of the user.
[0054] Specifically, the display assembly 21 is an optical machine used to output an image picture.
[0055] Further, the display assembly 20 further includes a control assembly 23 connected with the display assembly 21 to control the image picture output by the optical machine.
[0056] In some embodiments, the near-eye lens assembly 30 includes one of a dioptric assembly 33 and a flat light assembly. For example, the near-eye lens assembly 30 shown in FIGS. 2 and 3 is the dioptric assembly 33.
[0057] The dioptric assembly 33 includes but is not limited to a dioptric lens. The flat light assembly includes but is not limited to a flat light lens.
[0058] As shown in FIGS. 2 and 3, specifically, the dioptric assembly 33 is used to adjust the light rays input to the dioptric assembly 33 to meet the vision correction needs of the user. For example, under the condition that the user has vision correction needs, the image picture output by the display assembly 21 is transmitted by the optical waveguide assembly 22 and then enters the dioptric assembly 33. The light rays from the outside enter the dioptric assembly 33 through the optical waveguide assembly 22, and then the dioptric assembly 33 adjusts the input light signals so that the adjusted light signals reach the visual field of the user.
[0059] It should be understood that under the condition that there is no vision correction needs, the dioptric assembly 33 can be replaced by a flat light assembly. Then, the light rays from the outside and the image picture output by the display assembly 21 superimpose and pass through the flat light assembly to enter the visual field of the user.
[0060] In some embodiments, the dioptric assembly 33 comprises a dioptric lens with one flat side and one concave side, wherein if the dioptric assembly 33 is used to solve the user's myopia vision correction needs, the flat side of the dioptric lens faces the optical waveguide assembly 22, and the concave side of the dioptric lens faces away from the optical waveguide assembly 22, so that the size of the AR glasses 1 in the thickness direction of the dioptric assembly 33 can be further compressed, and it is convenient to control the distance between the dioptric lens and the optical waveguide assembly 22 in the production process.
[0061] Referring to FIG. 4, FIG. 4 is a structural schematic diagram of an embodiment of a dioptric assembly 33 of the AR glasses provided by the present application.
[0062] As shown in FIGS. 3 and 4, in other embodiments, the near-eye lens module 30 comprises a dioptric assembly 33, which is a dioptric lens with one concave side and one convex side, wherein if the dioptric assembly 33 is used to solve the user's myopia vision correction needs, the convex side of the dioptric lens faces the optical waveguide assembly 22, and the concave side of the dioptric lens faces away from the optical waveguide assembly 22.
[0063] Further, the convex side of the dioptric lens is relatively flat compared to the concave side of the dioptric lens, i.e., the flat side of the dioptric lens facing the optical waveguide lens is a flat surface with a micro-radian.
[0064] Preferably, the range of the radius R of the convex side of the dioptric lens facing the optical waveguide lens is greater than 130 mm, and the range of the convex height H is less than 2 mm.
[0065] In some embodiments, the optical waveguide assembly 22 comprises an optical waveguide lens and protective members arranged on the opposite sides of the optical waveguide lens, and the two protective members are respectively used to seal and protect the optical waveguide lens from both sides to improve the durability of the optical waveguide lens. It should be noted that the opposite sides of the optical waveguide lens refer to the side (near-eye end) of the optical waveguide lens close to the near-eye lens module 30 and the side away from the near-eye lens module 30.
[0066] Preferably, the protective members have light transmission properties to ensure that the overall light transmission performance of the optical waveguide assembly 22 is good. For example, the protective members are glass, such as CG (Cover Glass).
[0067] In other embodiments, the optical waveguide assembly 22 comprises an optical waveguide lens, and only the side of the optical waveguide lens away from the near-eye lens module 30 is provided with a protective member. That is, the side of the optical waveguide lens close to the near-eye lens module 30 is not provided with a protective member.
[0068] It should be understood that the protection member has a certain thickness, so in the embodiments of the present application, the AR glasses 1 are not provided with a protection member on the side close to the near-eye lens module 30, so that the size of the optical waveguide assembly 22 and the near-eye lens module 30 in the thickness direction is further compressed, and the AR glasses 1 are more portable. In addition, the side (near-eye end) of the optical waveguide lens close to the near-eye lens module 30 is provided with the near-eye lens module 30 and the first clamping mechanism 40 and the second clamping mechanism 50 clamped with each other, which ensures the sealing and protection effect of the optical waveguide lens.
[0069] It should be understood that, as shown in FIGS. 2 and 3, FIG. 2 shows a partial structure diagram of the AR glasses 1 provided by the embodiments of the present application. Preferably, the specific structure of the AR glasses 1 provided by the embodiments of the present application is as shown in FIG. 3, which has a bilateral structure for outputting and displaying image pictures on both sides of the AR glasses 1.
[0070] In some embodiments, the display assembly 21 at least includes a first display assembly 21 and a second display assembly 21, which correspond to the left and right eyes of the user, respectively, for outputting and displaying image pictures on both sides of the AR glasses 1.
[0071] It should be noted that, as shown in FIGS. 2 and 3, when the first clamping structure 40 and the second clamping structure 50 are clamped and matched with each other, the near-eye lens module 30 is installed on the frame assembly 11, and a certain interval is formed between the near-eye lens module 30 and the optical waveguide assembly 22 for optical design requirements. In addition, the clamping and matching of the first clamping structure 40 and the second clamping structure 50 are also beneficial to block dust, water vapor and the like from the outside into the interval between the near-eye lens module 30 and the optical waveguide assembly 22, so as to avoid affecting the quality of the AR glasses 1.
[0072] Therefore, the AR glasses 1 provided by the embodiments of the present application realize reliable fixation of the near-eye lens module 30 in the AR glasses 1 by clamping and matching the first clamping structure 40 and the second clamping structure 50, improve the detachability of the near-eye lens module 30, and make the AR glasses 1 convenient for repeated processing. In addition, the clamping of the first clamping structure 40 and the second clamping structure 50 also isolates the space between the near-eye lens module 30 and the optical waveguide assembly 22 from the outside.
[0073] In some embodiments, at least one of the first clamping structure 40 and the second clamping structure 50 is an elastic clamping structure, so that the near-eye lens module 30 and the frame assembly 11 are clamped and connected, and are convenient for mutual installation and disassembly. In addition, the elastic clamping structure provides a certain redundancy for the design of the near-eye lens module 30 in the length and width directions.
[0074] Please refer to FIG. 5, which is a connection scene diagram of the first clamping structure and the second clamping structure in an embodiment of the AR glasses provided by the embodiments of the present application.
[0075] As shown in FIG. 5(a), in some embodiments, the first snap structure 40 includes a first connecting groove 41 arranged on the side of the frame assembly 11 facing the near-eye lens module 30, and the second snap structure 50 includes a first elastic assembly 51 arranged on the side of the near-eye lens module 30 and used to form an elastic snap with the first connecting groove 41.
[0076] That is, at least the second snap structure 50 is an elastic snap structure.
[0077] For example, the first elastic assembly 51 includes an elastic rubber ring arranged on the side of the near-eye lens module 30, and when the first snap structure 40 and the second snap structure 50 are snap-fitted, the elastic rubber ring is at least partially accommodated in the first connecting groove 41 and forms a snap with the groove wall of the first connecting groove 41.
[0078] By arranging the first elastic assembly 51 on the side of the near-eye lens module 30, the mounting and fixing effect of the near-eye lens module 30 and the frame assembly 11 is improved, and the isolation effect of the space between the near-eye lens module 30 and the optical waveguide assembly 22 is improved.
[0079] For example, the elastic rubber ring is in interference fit with the groove wall of the second connecting groove 52, and the mounting and fixing effect of the near-eye lens module 30 and the frame assembly 11 and the isolation effect of the space between the near-eye lens module 30 and the optical waveguide assembly 22 are further improved.
[0080] As shown in FIG. 5(b), in some embodiments, the inner wall of the first connecting groove 41 is provided with a first elastic rubber layer 43 to improve the mounting and fixing effect of the near-eye lens module 30 and the frame assembly 11, and a certain redundancy is reserved for the design of the near-eye lens module 30 in the length and width directions.
[0081] As shown in FIGS. 5(a) and 5(b), in some embodiments, the near-eye lens module 30 is provided with a first receiving groove 31, and the first elastic assembly 51 is detachably connected with the near-eye lens module 30 through the first receiving groove 31.
[0082] Specifically, the first elastic assembly 51 can be accommodated in or separated from the first receiving groove 31 to realize the detachable connection of the first elastic assembly 51 and the near-eye lens module 30.
[0083] In some embodiments, the first receiving groove 31 is arranged relative to the frame assembly 11 and formed on the side of the near-eye lens module 30, and when the first elastic assembly 51 is connected and fitted with the near-eye lens module 30, the first elastic assembly 51 is partially protruded in the first receiving groove 31.
[0084] It should be noted that when the first elastic assembly 51 is detachably connected to the near-eye lens module 30, a part of the first elastic assembly 51 is accommodated in the first accommodation groove 31, and another part is exposed outside the first accommodation groove 31 and protrudes from the side of the near-eye lens module 30.
[0085] Referring to FIG. 6, FIG. 6 is a structural schematic diagram of the first elastic assembly in an embodiment of the AR glasses provided by the present application.
[0086] As shown in FIG. 6(a), in some embodiments, at least two first elastic assemblies 51 are provided, and the first elastic assembly 51 and the first connecting groove 41 form a two-point elastic structure engagement.
[0087] Specifically, at least two first elastic assemblies 51 are provided in the AR glasses 1, and the first connecting groove 41 is provided correspondingly to the first elastic assembly 51 and forms an elastic structure engagement with the at least two first elastic assemblies 51, respectively.
[0088] For example, the frame assembly 11 is formed with at least two first connecting grooves 41 near the side of the near-eye lens module 30, and the number and position of the first connecting grooves 41 correspond to the first elastic assembly 51. When the first engagement structure 40 and the second engagement structure 50 are engaged and matched, each first elastic assembly 51 is respectively engaged and connected to the first connecting groove 41 corresponding thereto.
[0089] Correspondingly, the side of the near-eye lens module 30 opposite to the first elastic assembly 51 is formed with a first accommodation groove 31. In some embodiments, the first accommodation groove 31 is provided with at least two, and the position of the first accommodation groove 31 corresponds to the near-eye lens module 30 to accommodate each first elastic assembly 51 correspondingly.
[0090] In some embodiments, the first elastic assembly 51 is provided at least on opposite sides of at least one of the length direction and the width direction of the near-eye lens module 30.
[0091] Specifically, the first elastic assembly 51 is provided at least on opposite sides of at least one of the length direction and the width direction of the near-eye lens module 30, so that the clamping effect of the frame assembly 11 on the near-eye lens module 30 is uniform, thereby improving the installation and fixing effect of the near-eye lens module 30 and the frame assembly 11. For example, when the first elastic assembly 51 is provided on opposite sides of the length direction of the near-eye lens module 30, the near-eye lens module 30 can be clamped and fixed uniformly from opposite sides of the length direction of the near-eye lens module 30.
[0092] Similarly, when the first elastic assembly 51 is arranged on the opposite sides of the near-eye lens module 30 in the width direction, or when the first elastic assembly 51 is arranged on the opposite sides of the near-eye lens module 30 in the width direction and the length direction, the frame assembly 11 can uniformly clamp the near-eye lens module 30, thereby improving the mounting and fixing effect of the near-eye lens module 30 and the frame assembly 11.
[0093] For example, as shown in FIG. 6(a), the first elastic assembly 51 is arranged on the opposite sides of the near-eye lens module 30 in the length direction and the width direction, thereby making the clamping and fixing of the near-eye lens module 30 more uniform.
[0094] As shown in FIG. 6(b), in some embodiments, the first elastic assembly 51 includes a first elastic ring 511 arranged on the outer circumferential side of the near-eye lens module 30, and the first elastic ring 511 and the first connecting groove 41 form an elastic structure clamping.
[0095] Specifically, the first elastic assembly 51 is arranged on the outer circumferential side of the near-eye lens module 30, and the first elastic assembly 51 cooperates with the frame assembly 11 to clamp and fix the near-eye lens module 30 from the circumferential direction, so that the frame assembly 11 uniformly clamps the near-eye lens module 30, thereby improving the mounting and fixing effect of the near-eye lens module 30 and the frame assembly 11.
[0096] 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 limited here.
[0097] As shown in FIG. 6(b), in some embodiments, the near-eye lens module 30 further includes a recessed avoidance position 32 formed in the first connecting groove 41 and used for adapting to an external workpiece, and when the first elastic assembly 51 is connected to the first receiving groove 31, the first elastic assembly 51 is arranged in the avoidance position 32.
[0098] Specifically, the external workpiece is, for example, a clamp device 2, and when the first elastic assembly 51 is connected to the first receiving groove 31, the first elastic assembly 51 is arranged in the avoidance position 32. When the clamp device 2 is clamped on the outer circumferential side of the first elastic assembly 51, and the clamping position is opposite to the avoidance position 32, the part of the first elastic assembly 51 between the clamp device 2 and the avoidance position 32 is displaced to the recessed direction of the avoidance position 32 and elastically deformed, so that when the clamp device 2 clamps the near-eye lens module 30 and the first elastic assembly 51, the required space occupied by the clamp device 2 in the radial direction of the near-eye lens module 30 is reduced, thereby facilitating the installation of the near-eye lens module 30 and the first elastic assembly 51 to the corresponding position on the frame assembly 11 when assembling the AR glasses 1.
[0099] Further, after the near-eye lens module 30 and the first elastic assembly 51 are installed to the corresponding positions on the frame assembly 11, the jig device 2 is detached from the near-eye lens module 30, and the deformation and displacement of the first elastic assembly 51 are restored, so that the first elastic assembly 51 is adapted to the first connecting groove 41 and the first receiving groove 31.
[0100] Please refer to FIG. 7, which is a structural schematic diagram of the first clamping structure and the second clamping structure in another embodiment of the AR glasses provided by the present application.
[0101] As shown in FIG. 7(a), in some embodiments, the second clamping structure 50 includes a second connecting groove 52 arranged on the side of the near-eye lens module 30 facing the frame assembly 11, and the first clamping structure 40 includes a second elastic assembly 42 arranged on the side of the frame assembly 11 and used to form elastic clamping with the second connecting groove 52.
[0102] That is, at least the first clamping structure 40 is an elastic clamping structure.
[0103] For example, the second elastic assembly 42 includes an elastic rubber ring arranged on the inner circumferential side of the frame assembly 11, and when the first clamping structure 40 and the second clamping structure 50 are clamped and adapted, the elastic rubber ring is at least partially accommodated in the second connecting groove 52 and clamped with the groove wall of the second connecting groove 52.
[0104] By arranging the second elastic assembly 42 on the inner circumferential side of the frame assembly 11, the installation and fixing effect of the near-eye lens module 30 and the frame assembly 11 is improved, and the isolation effect of the space between the near-eye lens module 30 and the optical waveguide assembly 22 is improved.
[0105] For example, the elastic rubber ring is in interference fit with the groove wall of the second connecting groove 52, which further improves the installation and fixing effect of the near-eye lens module 30 and the frame assembly 11 and the sealing effect of the space between the near-eye lens module 30 and the optical waveguide assembly 22.
[0106] As shown in FIG. 7(b), in some embodiments, a second elastic rubber layer 53 is arranged on the inner wall of the second connecting groove 52 to improve the installation and fixing effect of the near-eye lens module 30 and the frame assembly 11, and a certain redundancy is reserved for the design of the near-eye lens module 30 in the length and width directions.
[0107] As shown in FIGS. 7(a) and 7(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 with the frame assembly 11 through the second receiving groove 113.
[0108] Specifically, the second elastic assembly 42 can be accommodated in or detached from the second accommodating groove 113 to achieve detachable connection of the second elastic assembly 42 with the frame assembly 11. When the second elastic assembly 42 is detachably connected with the frame assembly 11, a part of the second elastic assembly 42 is accommodated in the second accommodating groove 113, and another part is exposed from the second accommodating groove 113 and protrudes to the inner circumferential side of the frame assembly 11.
[0109] Referring to FIG. 8, FIG. 8 is a schematic diagram of connection of the first clamping structure and the second clamping structure in another embodiment of the AR glasses provided by the present application.
[0110] As shown in FIG. 8(a), in some embodiments, the first clamping structure 40 includes a first connecting surface 44 formed on the side of the frame assembly 11 facing the near-eye lens module 30. The second clamping structure 50 includes a third elastic assembly 55 arranged on the side of the near-eye lens module 30 and used to form elastic clamping with the first connecting surface 44.
[0111] Specifically, when the first clamping mechanism and the second clamping mechanism are clamped and connected, the third elastic assembly 55 is clamped between the frame assembly 11 and the near-eye lens module 30 and is in interference fit with the inner side of the frame assembly 11 and the first connecting surface 44.
[0112] It should be noted that the volume of the third elastic assembly 55 is specifically designed according to the interval between the first connecting surface 44 on the frame assembly 11 and the near-eye lens module 30, specifically, the volume of the third elastic assembly 55 is designed to be in interference fit between the outer side of the first connecting surface 44 and the near-eye lens module 30, that is, when the first clamping mechanism and the second clamping mechanism are clamped and connected, the third elastic assembly 55 is in a state of elastic compression, so as to fasten the connection between the frame assembly 11 and the near-eye lens module 30.
[0113] Compared with the embodiment of opening a groove on the frame assembly 11 and the near-eye lens module 30, the embodiment of the present application reduces the difficulty of machining and re-machining of the near-eye lens module 30, and has better sealing effect on the space between the near-eye lens module 30 and the optical waveguide assembly 22, which is beneficial to block dust, water vapor and the like from the outside into the interval between the near-eye lens module 3030 and the optical waveguide assembly 2222, so as to avoid affecting the quality of the AR glasses 11.
[0114] For example, the first connecting surface 44 is arranged in a plane. For another example, the third elastic assembly 55 is, for example, a rubber ring sleeved on the outer side of the near-eye lens module 30.
[0115] As shown in FIG. 8(b), in some embodiments, the second snap structure 50 includes a second connecting surface 54 formed on the side of the near-eye lens module 30 facing the frame assembly 11; the first snap structure 40 includes a fourth elastic assembly 45 arranged on the side of the frame assembly 11 and configured to elastically snap with the second connecting surface 54.
[0116] Specifically, when the first snap structure and the second snap structure are snap-connected, the fourth elastic assembly 45 is clamped between the frame assembly 11 and the near-eye lens module 30 and is in interference fit with the second connecting surface 54 and the outer side of the near-eye lens module 30.
[0117] It should be noted that the volume of the fourth elastic assembly 45 is specifically designed according to the spacing between the second connecting surface 54 on the near-eye lens module 30 and the frame assembly 11, specifically, the volume of the fourth elastic assembly 45 is in interference fit between the inner side of the second connecting surface 54 and the frame assembly 11, that is, when the first snap structure and the second snap structure are snap-connected, the fourth elastic assembly 45 is in an elastically compressed state, so as to fasten the connection between the frame assembly 11 and the near-eye lens module 30.
[0118] Compared with the embodiment of opening a slot on the frame assembly 11 and the near-eye lens module 30, the embodiment of the present application reduces the difficulty of machining and re-machining the near-eye lens module 30, and has better sealing effect on the space between the near-eye lens module 30 and the optical waveguide assembly 22.
[0119] For example, the second connecting surface 54 is arranged in a plane. For another example, the fourth elastic assembly 45 is, for example, a rubber ring arranged on the inner side of the frame assembly 11.
[0120] It should be noted that, in order to improve the fastening and tightness of the third elastic member / fourth elastic member with the frame assembly 11 and the near-eye lens module 30, the frame assembly 11 can be connected by using adhesive on the side of the third elastic member / fourth elastic member close to the frame assembly 11, and the near-eye lens module 30 can be connected by using adhesive on the side of the third elastic member / fourth elastic member close to the near-eye lens module 30.
[0121] It should be noted that the third elastic assembly 55 and the fourth elastic assembly 45 can be the same elastic assembly. For example, the third elastic assembly 55 can be a ring-shaped elastic rubber ring, such as a rubber ring, and the fourth elastic assembly 45 is the same.
[0122] It should be further noted that when the third elastic member and the fourth elastic member are the same elastic member, the above two embodiments can be executed together.
[0123] Please refer to FIG. 9, which is a structural diagram of the first connecting surface and the second connecting surface in an embodiment of the AR glasses provided by the present application.
[0124] As shown in FIG. 8(a) and FIG. 9(a), in some embodiments, the first connecting surface 44 is formed with a first friction protrusion 541 to increase the friction between the third elastic component 55 and the first connecting surface 44 in the first direction, wherein the first direction is the direction of the optical waveguide assembly 22 relative to the near-eye lens module 30.
[0125] It should be noted that the first friction protrusion 541 provided on the first connecting surface 44 can effectively increase the friction between the third elastic component 55 and the first connecting surface 44 in the first direction, thereby preventing the third elastic component 55 from falling off between the frame assembly 11 and the near-eye lens module 30.
[0126] As shown in FIG. 8(b) and FIG. 9(b), in some embodiments, the second connecting surface 54 is formed with a second friction protrusion 542 to increase the friction between the fourth elastic component 45 and the second connecting surface 54 in the first direction, wherein the first direction is the direction of the optical waveguide assembly 22 relative to the near-eye lens module 30.
[0127] Similarly, the second friction protrusion provided on the second connecting surface 54 can effectively increase the friction between the fourth elastic component 45 and the second connecting surface 54 in the first direction, thereby preventing the fourth elastic component 45 from falling off between the frame assembly 11 and the near-eye lens module 30.
[0128] As shown in FIG. 3 and FIG. 5, in some embodiments, the interval between the near-eye lens module 30 and the optical waveguide assembly 22 in the first direction is 1-1000 μm, wherein the first direction is the direction of the near-eye lens module 10 relative to the optical waveguide assembly 22.
[0129] It should be noted that if the interval between the near-eye lens module 30 and the optical waveguide assembly 22 in the first direction is less than 1 um, the sub-micron level interval may cause diffraction fringes in the visible light band. On the contrary, if the interval is greater than 100 um, the near-eye lens module 30 and the optical waveguide assembly 22 in the first direction are not closely combined, resulting in a larger volume of the AR glasses 1.
[0130] In the embodiments of the present application, the first clamping structure 40 and the second clamping structure 50 are arranged to clamp and install the near-eye lens module 30 to the frame assembly 11, so that the spacing between the near-eye lens module 30 and the optical waveguide assembly 22 in the first direction is relatively fixed after installation, and the spacing range between the near-eye lens module 30 and the optical waveguide assembly 22 in the first direction is limited to 1-1000 μm. Compared with the existing fixing scheme of the near-eye lens module 30, such as the magnetic attraction or adhesive scheme, the thickness of the near-eye lens module 30 and the optical waveguide assembly 22 in the first direction is further effectively shortened, so that the AR glasses 1 are more portable.
[0131] In some embodiments, the frame assembly 11 is provided with a guide groove 114 on the side close to the near-eye lens module 30 for adapting to an external workpiece, wherein the width of the guide groove 114 on the side close to the temple assembly 12 is greater than the width of the side away from the temple assembly 12.
[0132] Specifically, as shown in FIGS. 17-18, the external workpiece is, for example, a clamp device 2. Since the width of the guide groove 114 on the side close to the temple assembly 12 is greater than the width of the side away from the temple assembly 12, in the process of clamping and transferring the near-eye lens module 30 by the clamp device 2 to install the near-eye lens module 30 to the frame assembly 11, under the guidance of the guide groove 114, the near-eye lens module 30 is more easily moved to the installation position matched with the near-eye lens module 30, so as to reduce the installation difficulty and reduce the installation error.
[0133] As shown in FIGS. 1-7, in some embodiments, the frame assembly 11 includes a lens mounting piece 111 and a temple connecting piece 112 connected with the temple assembly 12 and the lens mounting piece 111, and the lens mounting piece 111 is provided with the first clamping structure 40 to connect the near-eye lens module 30, wherein the optical waveguide assembly 22 is connected to the side of the lens mounting piece 111 away from the temple connecting piece 112.
[0134] Specifically, the first clamping structure 40 is arranged on the lens mounting piece 111, and the optical waveguide assembly 22 is connected to the side of the lens mounting piece 111 away from the temple connecting piece 112. It should be understood that the image picture output by the display assembly 21 is transmitted by the optical waveguide assembly 22 to enter the near-eye lens module 30, and the light rays from the outside of the AR glasses 1 enter the near-eye lens module 30 through the optical waveguide assembly 22, and then the near-eye lens module 30 adjusts the incoming light signal to make the adjusted light signal reach the user's field of view, so that when the user wears the AR glasses 1, the light rays from the outside of the AR glasses 1 and the image picture output by the display assembly 21 are transmitted by the optical waveguide assembly 22 and enter the user's field of view together.
[0135] Please refer to FIG. 10, which is a schematic view of a containing cavity in an embodiment of the AR glasses provided by the present application.
[0136] As shown in FIG. 10, in some embodiments, the frame assembly 11 further comprises a receiving cavity 60, which is arranged on the side of the lens mounting member 111 close to the temple assembly 12 and opposite to the in-coupling grating region 221 of the optical waveguide assembly 22, and the display assembly 21 is received in the receiving cavity 60.
[0137] It should be noted that at least one of the lens mounting member 111 and the temple connecting member 112 forms the receiving cavity 60, for example, in FIG. 10, the lens mounting member 111 forms the receiving cavity 60 on the side close to the temple connecting member 112. Specifically, the receiving cavity 60 is opposite to the in-coupling grating region 221 of the optical waveguide assembly 22 and is used to receive the display assembly 21, so that the image output by the display assembly 21 can accurately enter the in-coupling grating region 221 of the optical waveguide assembly 22.
[0138] As shown in FIGS. 1-10, in some embodiments, the lens mounting member 111 comprises a central portion 1111, and the first clamping structure 40 is arranged on the side of the central portion 1111 close to the temple assembly 12, and the optical waveguide assembly 22 is connected to the side of the central portion 1111 away from the temple assembly 12.
[0139] That is, the side of the lens mounting member 111 close to the first clamping structure 40 and the optical waveguide assembly 22 is in a "T-shaped structure", and the first clamping structure 40 and the optical waveguide assembly 22 are separated on the two sides of the "T-shaped structure".
[0140] It should be understood that the central portion 1111 separates the first clamping structure 40 and the optical waveguide assembly 22 to ensure the distance between the near-eye lens module 30 and the optical waveguide assembly 22, and also improves the overall strength of the AR glasses 1.
[0141] Please refer to FIGS. 11 and 12, FIG. 11 is a module structure diagram of another embodiment of AR glasses provided by the present application, and FIG. 12 is a structure diagram of another embodiment of AR glasses provided by the present application.

[0144] Please refer to FIG. 13, which is a step schematic flow chart of an AR glasses assembling method provided by an embodiment of the present application.
[0145] As shown in FIG. 13, the embodiment of the present application further provides an AR glasses 1 assembling method, which is at least used for assembling and generating any AR glasses 1 provided by the embodiment of the present application, wherein the AR glasses 1 assembling method specifically comprises steps S1 to S3:
[0146] Step S1: providing a frame assembly 11, a near-eye lens module 30 to be installed on the frame assembly 11 and a clamp device 2 for clamping the near-eye lens module 30;
[0147] Step S2: controlling the clamp device 2 to clamp and transfer the near-eye lens module 30, so that the second clamping structure 50 of the near-eye lens module 30 is clamped and connected with the first clamping structure 40 of the frame assembly 11;
[0148] Step S3: removing the clamp device 2 to obtain the AR glasses 1.

[0151] Correspondingly, in step S2, the control clamp device 2 clamps and transfers the near-eye lens module 30, including:
[0152] providing the first elastic assembly 51;
[0153] transferring the first elastic assembly 51 to the first receiving groove 31 so that the first elastic assembly 51 partially protrudes from the side of the near-eye lens module 30;
[0154] controlling the clamp device 2 to clamp the near-eye lens module 30 from the outside of the near-eye lens module 30;
[0155] transferring the near-eye lens module 30 and the first elastic assembly 51 by the clamp device 2 so that the first elastic assembly 51 is accommodated in the first connecting groove 41 and the first receiving groove 31.
[0156] Specifically, first, the provided first elastic assembly 51 is installed and adapted to the near-eye lens module 30, and the installation and adaptation of the first elastic assembly 51 to the near-eye lens module 30 specifically includes: transferring the first elastic assembly 51 to the first connecting groove 41 so that the first elastic assembly 51 partially protrudes from the side of the near-eye lens module 30.
[0157] It should be noted that FIG. 14(a) is a schematic view before the first elastic assembly 51 is transferred to the first connecting groove 41, and FIG. 14(b) is a schematic view after the first elastic assembly 51 is transferred to the first receiving groove 31.
[0158] It should be noted that the transfer of the first elastic assembly 51 to the first receiving groove 31 can be performed by a device or by an operator, and the present application does not make specific limitations.
[0159] As shown in FIG. 14 and FIG. 15, after the first elastic assembly 51 is installed and adapted to the near-eye lens module 30, the control clamp device 2 clamps the near-eye lens module 30 from the outside of the near-eye lens module 30, and transfers the near-eye lens module 30 and the first elastic assembly 51 by the clamp device 2 so that the first elastic assembly 51 is accommodated in the first connecting groove 41 and the first receiving groove 31.
[0160] As shown in FIG. 15, in some embodiments, when the clamp device 2 is clamped on the outer circumferential side of the first elastic assembly 51, the clamp device 2 pushes the first elastic assembly 51 in the direction of the recess of the first receiving groove 31, so as to at least cause the part of the first elastic assembly 51 between the clamp device 2 and the first receiving groove 31 to be displaced and / or compressed.
[0161] Referring to FIG. 16, FIG. 16 is a schematic view of transferring the near-eye lens module in another embodiment of the AR glasses assembly method provided by the present application.
[0162] As shown in FIGS. 2-3 and 16, in some embodiments, the AR glasses 1 assembly method provided by the present application further comprises:
[0163] controlling the clamp device 2 to clamp the near-eye lens module 30 from the outside of the near-eye lens module 30, so as to compress the first elastic assembly 51 towards the first connecting groove 41;
[0164] wherein, after the clamp device 2 is detached from the near-eye lens module 30, the deformation of the first elastic assembly 51 is restored, so as to adapt the first elastic assembly 51 to the first connecting groove 41 and the first receiving groove 31.
[0165] Specifically, when the clamp device 2 is clamped on the outer circumferential side of the first elastic assembly 51, the clamp device 2 pushes the first elastic assembly 51 in the direction of the recess of the first receiving groove 31, and the part of the first elastic assembly 51 between the clamp device 2 and the first receiving groove 31 is displaced and / or compressed, and after the clamp device 2 is detached from the near-eye lens module 30, the deformation of the first elastic assembly 51 is restored, so as to adapt the first elastic assembly 51 to the first connecting groove 41 and the first receiving groove 31.
[0166] wherein, FIGS. 2-3 can be regarded as a schematic view of the deformation recovery of the first elastic assembly 51 after the clamp device 2 is detached from the near-eye lens module 30, and it can be seen that part of the first elastic assembly 51 is adapted to the first connecting groove 41, and part of the first elastic assembly 51 is adapted to the first receiving groove 31, thereby mounting and fixing the near-eye lens module 30 and the frame assembly 11, and improving the isolation effect of the interval between the near-eye lens module 30 and the optical waveguide assembly 22 through the design of the first elastic assembly 51.
[0167] It should be further noted that, when the clamp device 2 clamps the near-eye lens module 30 and the first elastic assembly 51, the elastic design of the first elastic assembly 51 reduces the space required by the clamp device 2 in the radial direction of the near-eye lens module 30, so as to facilitate the positioning of the near-eye lens module 30 and the first elastic assembly 51 on the corresponding position of the frame assembly 11.
[0168] As shown in FIG. 6(b), FIG. 14 and FIG. 15, in some embodiments, the near-eye lens module 30 further comprises a recessed avoiding position 32 formed in the first connecting groove 41 and used for adapting 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 wrapped in the avoiding position 32;
[0169] controlling the clamp device 2 to clamp the near-eye lens module 30 from the outside of the near-eye lens module 30 comprises:
[0170] controlling the clamp device 2 to clamp the near-eye lens module 30 from the outside of the near-eye lens module 30 comprises:
[0171] Specifically, the clamp device 2 comprises at least two clamping pieces 201, when each clamping piece 201 is pushed in the opposite direction of the near-eye lens module 30, the clamp device 2 can clamp the near-eye lens module 30 and the first elastic component 51. Among them, in the process of controlling the clamp device 2 to clamp the near-eye lens module 30 from the outside of the near-eye lens module 30, at least one clamping piece 201 in the clamp device is pushed towards the avoiding position 32, so that at least part of the first elastic component 51 located in the first connecting groove 41 is compressed or displaced in the recessed direction of the avoiding position 32. Thus, when the clamp device 2 clamps the near-eye lens module 30 and the first elastic component 51, the space occupied by the clamp device 2 in the radial direction of the near-eye lens module 30 is reduced, which facilitates the installation of the near-eye lens module 30 and the first elastic component 51 to the corresponding position on the frame assembly 11 when assembling the AR glasses 1.
[0172] After controlling the clamp device 2 to clamp the near-eye lens module 30 from the outside of the near-eye lens module 30, the near-eye lens module 30 and the first elastic component 51 are transferred by the clamp device 2, so that the first elastic component 51 is accommodated in the first connecting groove 41 and the first accommodating groove 31, and the clamp device 2 is removed, so as to install and fix the near-eye lens module 30 and the frame assembly 11.
[0173] Please refer to FIG. 17, which is a schematic diagram of transferring the near-eye lens module and the first elastic component in an embodiment of the AR glasses assembly method provided by the present application.
[0174] As shown in FIG. 17, in some embodiments, the step S2 of transferring the near-eye lens module 30 and the first elastic component 51 by the clamp device 2 comprises:

[0176] The near-eye glass module 30 clamped by the clamp device 2 is pushed to move in the direction of the frame assembly 11 by the preset pressing tool 3, so that the first elastic assembly 51 is opposite to the first connecting groove 41.
[0177] Specifically, as shown in FIG. 17(a), the clamp device 2 is first controlled to move the near-eye glass module 30 to the side away from the optical waveguide assembly 22 of the frame assembly 11, and then, as shown in FIG. 17(b), the preset pressing tool 3 is used to provide pressure to the near-eye glass module 30, and the pressure direction is the direction of the near-eye glass module 30 to the frame assembly 11, so that the near-eye glass module 30 clamped by the clamp device 2 is pushed to move in the direction of the frame assembly 11, so that the first elastic assembly 51 is opposite to the first connecting groove 41. For details, refer to the positional relationship between the first elastic assembly 51 and the first connecting groove 41 as shown in FIG. 17(c).
[0178] In some embodiments, the control of the clamp device 2 to clamp the near-eye glass module 30 from the outside of the near-eye glass module 30 includes: controlling the clamp device 2 to clamp the near-eye glass module 30 from the side of the near-eye glass module 30 by the rear end of the clamp device 2.
[0179] The control of the clamp device 2 to move the near-eye glass module 30 to the side away from the optical waveguide assembly 22 of the frame assembly 11 includes: controlling the clamp device 2 to move so that the front end of the clamp device 2 abuts against the frame assembly 11.
[0180] Specifically, in the present embodiment, the near-eye glass module 30 is first clamped from the side of the near-eye glass module 30 by the rear end of the clamp device 2, and then the clamp device 2 is controlled to move so that the front end of the clamp device 2 abuts against the frame assembly 11. Then, the near-eye glass module 30 clamped by the clamp device 2 is pushed to move in the direction of the frame assembly 11 by the preset pressing tool 3, so that the first elastic assembly 51 is opposite to the first connecting groove 41. This facilitates the alignment of the near-eye glass module 30 and the frame assembly 11 during assembly of the AR glasses 1, and reduces the precision requirement of moving the clamp device 2.
[0181] As shown in FIG. 15 and FIG. 16, the clamp device 2 includes at least two clamping members 201, and the clamping member 201 specifically includes oppositely arranged first clamping portion 2011 and second clamping portion 2012, 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. The clamp device 2 is controlled to clamp the near-eye lens module 30 from the side of the near-eye lens module 30 by the second clamping portion 2012, and then the clamp device 2 is controlled to move so that the first clamping portion 2011 of the clamp device 2 abuts against the frame assembly 11. The near-eye lens module 30 clamped on the clamp device 2 is pushed to move towards the frame assembly 11 by using a preset pressing tool 3, so that the first elastic assembly 51 is opposite to the first connecting groove 41, thereby accurately feeding the near-eye lens module 30 and the first elastic assembly 51 into the corresponding installation position.
[0182] As shown in FIG. 14 and FIG. 15, in some embodiments, the clamp device 2 includes at least two clamping members 201 for clamping the near-eye lens module 30. The clamping member 201 includes the first clamping portion 2011 at the front end of the clamping member 201 and the second clamping portion 2012 at the rear end of the clamping member 201. 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 near-eye lens module 30.
[0183] Specifically, the second direction is opposite to the direction in which the clamping member 201 clamps the near-eye lens module 30 (as shown in FIG. 15), 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 clamp device 2 is controlled to clamp the near-eye lens module 30 from the side of the near-eye lens module 30 by the second clamping portion 2012, the second clamping portion 2012 with greater thickness clamps the near-eye lens module 30 more stably. When the clamp device 2 is controlled to move, the clamp device 2 is more easily transferred to abut against the frame assembly 11 under the guidance of the first clamping portion 2011.
[0184] As shown in FIG. 1 to FIG. 15, it is to be noted that the AR glasses 1 assembly method flowchart shown in FIG. 13 only includes the process of installing the near-eye lens module 30 on the frame module 10. In some embodiments, before installing the near-eye lens module 30 on the frame module 10, the process further includes:
[0185] Installing the display assembly 21 and / or the optical waveguide assembly 22 on the frame module 10.
[0186] Specifically, the specific structure diagram of installing the display assembly 21 and the optical waveguide assembly 22 on the frame module 10 can be referred to FIG. 2 to FIG. 5. For example, the display assembly 21 and / or the optical waveguide assembly 22 are installed and fixed on the frame module 10 by adhesive.
[0187] It should be noted that the AR glasses 1 assembly method provided in the embodiments of the present application first fixes and installs the display assembly 21 and the optical waveguide assembly 22 on the frame assembly 11 in the assembly process of the AR glasses 1, and then installs the near-eye lens module 30 on the frame assembly 11 through the detachable first clamping structure 40 and the second clamping structure 50, and the installation of the near-eye lens module 30 is more convenient and low in cost. On the basis of the installation of the display assembly 21 and the optical waveguide assembly 22, the near-eye lens module 30 can be repeatedly trimmed or replaced for many times.
[0188] For example, different users may have different vision correction needs, or multiple refractions and polishing of the near-eye lens module 30 are required in the lens fitting process of the user, or the user is still not satisfied with the refractive effect of the near-eye lens module 30 after the installation of the near-eye lens module 30. In these scenarios, the AR glasses 1 assembly method provided in the embodiments of the present application improves the detachability of the near-eye lens module 30 and facilitates the repeated processing of the AR glasses 1.
[0189] In some embodiments, before the control clamp device 2 clamps and transfers the near-eye lens module 30, it further includes:
[0190] transferring the optical waveguide assembly 22 from the opposite direction of the first direction to the frame assembly 11;
[0191] The clamp device 2 transfers the near-eye lens module 10 specifically from the first direction to the frame assembly 11, and the first direction is the direction of the near-eye lens module 10 relative to the optical waveguide assembly 22 after the installation of the AR glasses 1 is completed.
[0192] It should be understood that in the embodiments of the present application, the installation direction of the optical waveguide assembly 22 and the near-eye lens module 30 is opposite, specifically, the lens mounting member 111 includes a center portion 1111, the first clamping structure 40 is arranged on one side of the center portion 1111 close to the temple assembly 12, and the optical waveguide assembly 22 is connected to the other side of the center portion 1111 away from the temple assembly 12. It can be seen that the center portion 1111 separates the first clamping structure 40 and the optical waveguide assembly 22 to ensure the distance between the near-eye lens module 30 and the optical waveguide assembly 22, and also improves the overall strength of the AR glasses 1.
[0193] As shown in FIG. 15 and FIG. 16, the embodiment of the present application further provides a clamp device 2 for assembling any one of the AR glasses 1 provided by the embodiment of the present application, the clamp device 2 comprises at least two clamping pieces 201 for clamping target lenses, the clamping piece 201 comprises a first clamping part 2011 at the front end of the clamping piece 201 and a second clamping part 2012 at the rear end of the clamping piece 201, wherein the thickness of the second clamping part 2012 in the second direction is less than the thickness of the first clamping part 2011, and the second direction is opposite to the direction in which the clamping piece 201 clamps the near-eye lens module 30.
[0194] Specifically, the second direction is opposite to the direction in which the clamping piece 201 clamps the near-eye lens module 30 (as shown in FIG. 15), and the thickness of the second clamping part 2012 in the second direction is less than the thickness of the first clamping part 2011, so that when the clamp device 2 is controlled to clamp the near-eye lens module 30 from the side of the near-eye lens module 30 by the second clamping part 2012, the clamping of the near-eye lens module 30 by the second clamping part 2012 with greater thickness is more stable, and when the clamp device 2 is controlled to move, the clamp device 2 is more easily transferred to abut against the frame assembly 11 under the guidance of the first clamping part 2011.
[0195] In some embodiments, the thickness of the second clamping part 2012 in the second direction is 0.02-0.4mm.
[0196] Specifically, the thickness of the second clamping part 2012 in the second direction is less than the thickness of the first clamping part 2011, and the thickness of the second clamping part 2012 in the second direction is 0.02-0.4mm, so that when the clamp device 2 is controlled to move, the clamp device 2 is more easily transferred to abut against the frame assembly 11 under the guidance of the first clamping part 2011.
[0197] Please refer to FIG. 18, which is a schematic view of the AR glasses transferring the near-eye lens module 30 and the first elastic assembly provided by the embodiment of the present application.
[0198] As shown in FIG. 18, in some embodiments, the at least one second clamping part 2012 is a flexible piece.
[0199] It should be noted that by designing the at least one second clamping part 2012 as a flexible part, even if the near-eye lens module 30 cannot be aligned with the corresponding mounting position during the process of transferring the near-eye lens module 30 by the clamp device 2 as shown in FIG. 18(a), the flexible second clamping part 2012 can still guide the near-eye lens module 30 to the corresponding mounting position when the near-eye lens module 30 is pushed towards the frame assembly 11, and FIG. 18(b) is a specific diagram of pushing the second clamping part 2012 to guide the near-eye lens module 30 to the mounting position, thereby, the embodiment of the present application facilitates the alignment of the near-eye lens module 30 with the frame assembly 11 during the assembly of the AR glasses 1, and reduces the precision requirement of moving the clamp device 2.
[0200] As shown in FIGS. 15-18, in some embodiments, the clamp device 2 is used to clamp and transfer the target lens to connect the target lens with the frame assembly 11, and the first clamping part 2011 is formed with a guide structure 2013 adapted to the frame assembly 11 on the side close to the second direction. It should be understood that the target lens refers to the refractive lens in the near-eye lens module 30, for example.
[0201] For example, as shown in FIGS. 17(a) and (b), specifically, the guide structure 2013 is used to guide the transfer of the clamp device 2 during the process of clamping and transferring the near-eye lens module 30 by the clamp device 2, so that the first clamping part 2011 of the clamp device 2 abuts against the frame assembly 10, thereby improving the accuracy of the transfer; or, the guide structure 2013 is used to guide the movement of the near-eye lens module 30 when the near-eye lens module 30 clamped on the clamp device 2 is pushed by the preset pressing tool 3 towards the frame assembly 11, so that the near-eye lens module 30 accurately enters the corresponding mounting position.
[0202] Referring to FIG. 19, FIG. 19 is a schematic diagram of a module of the clamp device 2 according to an embodiment of the present application.
[0203] As shown in FIG. 19, in some embodiments, the clamp device 2 further comprises a driving part 202 connected with at least one of the two clamping parts 201 and used to drive the at least two clamping parts 201 to move towards or away from each other.
[0204] It should be understood that the at least two clamping parts 201 form a clamping opening through which the near-eye lens module 30 is clamped, and the driving part 202 drives the at least two clamping parts 201 to move towards or away from each other, so as to adjust the size of the clamping opening, thereby achieving the control of clamping and unclamping the near-eye lens module 30.
