Description

Technical Field

[0001] This application relates to the technical field of near-eye display devices, and more specifically, to a lens clamping assembly and a near-eye display device. Background Art

[0002] A near-eye display device is a platform for a display means that presents information concentrated in front of the eyes. In a near-eye display device, an image created by a relatively small display screen reaches the human eye through small-sized optical devices. Essentially, it is to use some optical projection methods to enable the human eye to clearly see an image source located near the human eye, and place the image source located near the human eye within the visible range where the human eye can normally see light, so as to achieve the effect of virtual imaging.

[0003] From an application perspective, near-eye display devices can include AR (Augmented Reality) glasses. AR glasses can superimpose virtual objects or information produced by a computer onto the real scene, thus providing a new experience of virtual-real interaction and presenting richer and more effective information to users. Among the population wearing AR glasses, there are usually audience groups suffering from refractive errors (such as myopia, hyperopia, astigmatism). To achieve a good wearing experience, corrective lenses for refractive errors usually need to be installed in AR glasses.

[0004] Currently, the industry usually adopts additional frames with magnetic components and customized lenses with magnetic components to address the problem of installing corrective lenses for refractive errors. However, in the above solutions, since additional frames with magnetic components need to be added, it will increase the need for the internal space design of the frame. In addition, limited by the frame, corrective lenses for refractive errors need to be customized additionally. At the same time, the frame is usually installed on the front side and the rear side (relative to the human eye) of the frame, affecting the overall aesthetics and user experience.

[0055] Figure 3 is a perspective schematic diagram of a second clamping mechanism in the lens clamping assembly provided by an embodiment of this application.

[0056] Such as Figures 1 to 3As shown, the lens clamping assembly 100 may include a first clamping mechanism 110 and a second clamping mechanism 120. The first clamping mechanism 110 may include a first main body portion 111, a first sliding portion 112, and a first mounting guide portion 113. The first sliding portion 112 is slidable relative to the first main body portion 111 to clamp the lens L, and the first mounting guide portion 113 is provided on the first main body portion 111. The second clamping mechanism 120 may include a second main body portion 121, a second sliding portion 122, and a second mounting guide portion 123. The second sliding portion 122 is slidable relative to the second main body portion 121 to clamp the lens L, and the second mounting guide portion 123 is provided on the second main body portion 121. The first mounting guide portion 113 is fixedly connected to the first main body portion 111, and the second mounting guide portion 123 is detachably connected to the second main body portion 121. It should be noted that the lens L may be a refractive correction lens and has a refractive power adjustment function. For example, the lens L may include, but is not limited to, a myopia lens, a hyperopia lens, and an astigmatism lens.

[0057] According to the lens clamping assembly 100 provided in the above embodiment, the first main body portion 111 and the first sliding portion 112 in the first clamping mechanism 110, and the second main body portion 121 and the second sliding portion 122 in the second clamping mechanism 120 jointly clamp the single-piece lens L. The first mounting guide portion 113 is fixedly connected to the first main body portion 111 and the second mounting guide portion 123 is detachably connected to the second main body portion 121, which can enable the first mounting guide portion 113 and the second mounting guide portion 123 to be detachably connected to an external frame conveniently, contributing to the flexible disassembly and assembly of the lens L. In addition, the first clamping mechanism 110 and the second clamping mechanism 120 occupy a small space, and the lens L does not need to be customized additionally, which helps to improve the adaptability of the lens L.

[0058] In some embodiments, as Figure 1 and Figure 2 shown, the first main body portion 111 may include a first support portion 1111 and a first bending portion 1112. The first support portion 1111 may be generally flat and may be used to provide a first clamping surface 1113. The first bending portion 1112 may be bent at the end of the first support portion 1111 in a direction perpendicular to the first clamping surface 1113 along the first support portion 1111. The cross-sectional shape of the first main body portion 111 is generally L-shaped. The first support portion 1111 and the first bending portion 1112 may be integrally formed.

[0059] In some embodiments, the first bending portion 1112 may be provided with a first guide hole 114. The first guide hole 114 may extend in a direction perpendicular to the first clamping surface 1113. For example, the number of the first guide holes 114 may be two. The two first guide holes 114 may be arranged substantially collinearly. It should be noted that the number and arrangement manner of the first guide holes 114 are not specifically limited in this application.

[0060] In some embodiments, the first bending portion 1112 may further be provided with a first threaded hole 115. The first threaded hole 115 may extend in a direction perpendicular to the first clamping surface 1113.

[0061] In some embodiments, the first sliding portion 112 may be substantially plate-shaped and may be used to provide a second clamping surface 1121. For example, the first sliding portion 112 may be substantially the same size as the first support portion 1111. The first sliding portion 112 and the first support portion 1111 may be disposed opposite to each other. In other words, the first clamping surface 1113 and the second clamping surface 1121 may be disposed opposite to each other.

[0062] In some embodiments, the first sliding portion 112 may be provided with a first guiding member 116. The first guiding member 116 may be a columnar structure extending in a direction perpendicular to the second clamping surface 1121. For example, the number of the first guiding members 116 may be two. The two first guiding members 116 may be disposed substantially collinearly. It should be noted that the number and arrangement manner of the first guiding members 116 are not specifically limited in this application. The extension dimension of the first guiding member 116 and the cross-sectional dimension perpendicular to the extension direction match the extension dimension of the first guiding hole 114 and the cross-sectional dimension perpendicular to the extension direction. For example, the extension dimension of the first guiding member 116 may be less than or equal to the extension dimension of the first guiding hole 114. The cross-sectional dimension of the first guiding member 116 may be less than or equal to the cross-sectional dimension of the first guiding hole 114.

[0063] In some embodiments, the first sliding portion 112 may further be provided with a first locking member 117. The first locking member 117 may be implemented as a screw, such as a non-removable screw. The screw may be disposed in a direction perpendicular to the second clamping surface 1121. When a non-removable screw is selected, it can prevent the first locking member 117 from falling off during the sliding process.

[0064] In some embodiments, buffer pads 131 may be provided on both the first clamping surface 1113 and the second clamping surface 1121. The buffer pads 131 may be made of an elastic material (such as soft rubber). The buffer pads 131 can prevent damage to the lens L during the clamping process. In addition, due to the free compression characteristic of the elastic material (such as soft rubber), the lens L can be clamped more firmly.

[0065] In some embodiments, the first mounting guiding portion 113 may be provided on the first bending portion 1112. For example, the first mounting guiding portion 113 may be provided on a side of the first bending portion 1112 away from the first clamping surface 1113. The first mounting guiding portion 113 may be implemented as a protrusion. In addition, the first mounting guiding portion 113 and the first main body portion 111 may be integrally formed. In other words, the first mounting guiding portion 113 and the first main body portion 111 may be fixedly connected.

[0066] In some embodiments, when the first installation guiding portion 113 is implemented as a protrusion, the protrusion may include, but is not limited to, a cylindrical protrusion, a prismatic protrusion, a cuboid protrusion, or any other irregularly shaped protrusion. When the formation of the protrusion is plane-symmetrical, a chamfer may be formed on one side of the protrusion so that the protrusion has a non-plane-symmetrical shape, thereby playing an anti-misassembly role when it is installed with an external component.

[0067] In some embodiments, the first main body portion 111, the first sliding portion 112, and the first installation guiding portion 113 may be made of materials such as plastic, rubber, or light metals (e.g., aluminum and titanium) to reduce their own weight and contribute to weight reduction.

[0068] During the process of clamping the lens L by the first clamping mechanism 110, the first support portion 1111 in the first main body portion 111 is disposed opposite to the first sliding portion 112, and the lens L is placed between the first support portion 1111 and the first sliding portion 112. The first guiding member 116 extends into the first guiding hole 114. The first locking member 117 extends into the first threaded hole 115. Under the guiding action of the first guiding member 116 and the first guiding hole 114, the first sliding portion 112 slides relative to the first main body portion 111 until the lens L contacts the first clamping surface 1113 and the second clamping surface 1121. Subsequently, the first sliding portion 112 and the first main body portion 111 can be kept in a state of clamping the lens L by tightening the first locking member 117.

[0069] It should be noted that the fastening of the first main body portion 111 and the first sliding portion 112 by the first locking member 117 and the first threaded hole 115 described above is only an example. In other embodiments, the first main body portion 111 and the first sliding portion 112 may be fastened by a spring (e.g., a torsion spring) or a magnetic attracting member to achieve the clamping of the lens L. For example, when the first main body portion 111 and the first sliding portion 112 are fastened by a spring (e.g., a torsion spring), the first main body portion 111 and the first sliding portion 112 may be implemented as a U-shaped clip or a V-shaped clip. Without departing from the teachings of the present application, the present application does not specifically limit the shapes of the first main body portion 111 and the first sliding portion 112 and the fastening method.

[0070] In some embodiments, as Figure 1 and Figure 3 shown, the second main body portion 121 may include a second support portion 1211 and a second bending portion 1212. The second support portion 1211 may be generally in the shape of a flat plate and may be used to provide a third clamping surface 1213. The second bending portion 1212 may be bent at the end of the second support portion 1211 in a direction perpendicular to the third clamping surface 1213 along the second support portion 1211. The cross-sectional shape of the second main body portion 121 is generally L-shaped. The second support portion 1211 and the second bending portion 1212 may be integrally formed.

[0071] In some embodiments, the second bending portion 1212 may be provided with a second guiding hole 124. The second guiding hole 124 may extend in a direction perpendicular to the third clamping surface 1213. For example, the number of the second guiding holes 124 may be two. The two second guiding holes 124 may be arranged substantially collinearly. It should be noted that the present application does not specifically limit the number and arrangement manner of the second guiding holes 124.

[0072] In some embodiments, the second bending portion 1212 may also be provided with a second threaded hole 125. The second threaded hole 125 may extend in a direction perpendicular to the third clamping surface 1213.

[0073] In some embodiments, the second sliding portion 122 may be substantially in the shape of a flat plate and may be used to provide a fourth clamping surface 1221. For example, the second sliding portion 122 may have substantially the same size as the second supporting portion 1211. The second sliding portion 122 and the second supporting portion 1211 may be disposed opposite to each other. In other words, the third clamping surface 1213 and the fourth clamping surface 1221 may be disposed opposite to each other.

[0074] In some embodiments, the second sliding portion 122 may be provided with a second guiding member 126. The second guiding member 126 may be a columnar structure extending in a direction perpendicular to the fourth clamping surface 1221. For example, the number of the second guiding members 126 may be two. The two second guiding members 126 may be arranged substantially collinearly. It should be noted that the present application does not specifically limit the number and arrangement manner of the second guiding members 126. The extension dimension of the second guiding member 126 and the cross-sectional dimension perpendicular to the extension direction match the extension dimension of the second guiding hole 124 and the cross-sectional dimension perpendicular to the extension direction. For example, the extension dimension of the second guiding member 126 may be less than or equal to the extension dimension of the second guiding hole 124. The cross-sectional dimension of the second guiding member 126 may be less than or equal to the cross-sectional dimension of the second guiding hole 124.

[0075] In some embodiments, the second sliding portion 122 may also be provided with a second locking member 127. The second locking member 127 may be implemented as a screw, such as a non-removable screw. The screw may be arranged in a direction perpendicular to the fourth clamping surface 1221. When a non-removable screw is selected, it can prevent the second locking member 127 from falling off during the sliding process.

[0076] In some embodiments, buffer pads 131 may be provided on both the third clamping surface 1213 and the fourth clamping surface 1221. The buffer pads 131 may be made of an elastic material (e.g., soft rubber). The buffer pads 131 can prevent damage to the lens L during the clamping process. In addition, due to the free compression characteristic of the elastic material (e.g., soft rubber), the lens L can be clamped more firmly.

[0077] In some embodiments, the second main body portion 121 may be provided with a mounting groove 128. For example, the mounting groove 128 may be provided on a side of the second bending portion 1212 away from the third clamping surface 1213. A part of the second mounting guiding portion 123 may extend into the mounting groove 128. Hereinafter, the part of the second mounting guiding portion 123 extending into the mounting groove 128 is referred to as the first part, and the part of the second mounting guiding portion 123 not extending into the mounting groove 128 is referred to as the second part. In other words, the second mounting guiding portion 123 and the second main body portion 121 may be detachably connected. In addition, the second mounting guiding portion 123 is made of an elastic material. For example, the elastic material may include but is not limited to silica gel.

[0078] In some embodiments, the mounting groove 128 may be a through groove. From the perspective of the extending direction of the through groove, the cross-sectional shape of the mounting groove 128 may be generally in a T shape. Correspondingly, the cross-sectional shape of the first part of the second mounting guiding portion 123 may be generally in a T shape. In this embodiment, the use of the mounting groove 128 and the second mounting guiding portion 123 with a T-shaped cross-sectional shape helps to make the connection between the two more stable.

[0079] In some embodiments, the second part of the second mounting guiding portion 123 is trapezoidal. For example, the cross-sectional shape of the second part of the second mounting guiding portion 123 in a plane perpendicular to the extending direction of the through groove is trapezoidal, and the cross-sectional shape of the second part in a plane parallel to the extending direction of the through groove is also trapezoidal. Among them, in the above trapezoid, the two relatively parallel sides are parallel to the second bending portion 1212, and the longer of the two relatively parallel sides is closer to the second bending portion 1212. In this embodiment, the second part of the second mounting guiding portion 123 being trapezoidal can play a guiding role when it is installed with an external component, thus facilitating the installation.

[0080] In some embodiments, the second main body portion 121, the second sliding portion 122, and the second mounting guiding portion 123 may be made of materials such as plastics, rubber, or light metals (such as aluminum and titanium) to reduce their own weight and help achieve lightweight.

[0081] During the process of clamping the lens L by the second clamping mechanism 120, the second support portion 1211 in the second main body portion 121 is disposed opposite to the second sliding portion 122, and the lens L is placed between the second support portion 1211 and the second sliding portion 122. The second guide member 126 extends into the second guide hole 124. The second locking member 127 extends into the second threaded hole 125. Under the guiding action of the second guide member 126 and the second guide hole 124, the second sliding portion 122 slides relative to the second main body portion 121 until the lens L contacts the third clamping surface 1213 and the fourth clamping surface 1221. Subsequently, the second sliding portion 122 and the second main body portion 121 can be fastened to maintain the clamping state of the lens L by tightening the second locking member 127. It should be noted that the lens L can be a lens that has been clamped by the first clamping mechanism 110 or a lens that has not been clamped by the first clamping mechanism 110.

[0082] It should be noted that the fastening of the second main body portion 121 and the second sliding portion 122 by the second locking member 127 and the second threaded hole 125 described above is only an example. In other embodiments, the second main body portion 121 and the second sliding portion 122 can be fastened by a spring (e.g., a torsion spring) or a magnetic attracting member to realize the clamping of the lens L. For example, in the case where the second main body portion 121 and the second sliding portion 122 can be fastened by a spring (e.g., a torsion spring), the second main body portion 121 and the second sliding portion 122 can be implemented as a U-shaped clip or a V-shaped clip. Without departing from the teachings of the present application, the present application does not specifically limit the shapes of the second main body portion 121 and the second sliding portion 122 and the fastening method.

[0083] In the above embodiment, the first installation guiding portion 113 is fixedly connected to the first main body portion 111, the second installation guiding portion 123 is detachably connected to the second main body portion 121, and at the same time, the second installation guiding portion 123 is made of an elastic material. After the first clamping mechanism 110 and the second clamping mechanism 120 clamp the lens L at the same time, the lens clamping assembly 100 can carry the lens L and be assembled with an external component (e.g., the frame of a near-eye display device).

[0084] Figure 4 It is a perspective view of the second clamping mechanism in the lens clamping assembly provided by another embodiment of the present application. For the purpose of concise description, the same content as in the previous embodiment will not be repeated in the present application. For example, in this embodiment, the first clamping mechanism is the same as the first clamping mechanism 110 in the previous embodiment, and will not be repeated in the present application. In addition, the same reference numerals refer to the same components.

[0085] In some embodiments, such as Figure 4As shown, in the second clamping mechanism 120, the second main body portion 121 may be provided with an installation positioning hole 129. For example, the installation positioning hole 129 may be provided on a side of the second bending portion 1212 away from the third clamping surface 1213. The installation positioning hole 129 may be a blind hole extending perpendicular to the surface of the second bending portion 1212. The installation positioning hole 129 may play a role in positioning the second installation guiding portion 123'. At least a part of the outer surface of the second installation guiding portion 123' may be provided with threads, and a part of the second installation guiding portion 123' extends into the installation positioning hole 129. In other words, the second installation guiding portion 123' and the second main body portion 121 are detachably connected. For example, the second installation guiding portion 123' may be implemented as a stud.

[0086] In the above embodiment, the first installation guiding portion 113 is fixedly connected to the first main body portion 111, and the second installation guiding portion 123' is detachably connected to the second main body portion 121. After the first clamping mechanism 110 and the second clamping mechanism 120 clamp the lens L, the lens clamping assembly 100 can carry the lens L and assemble it with an external component (for example, the frame of a near-eye display device).

[0088] In some embodiments, as Figure 5 and Figure 6 shown, the lens clamping assembly 100 may further include a first extension portion 141 and a second extension portion 142. The first extension portion 141 may be embedded in the first main body portion 111 and be slidable relative to the first main body portion 111 in a direction parallel to the first clamping surface 1113. The second extension portion 142 may be embedded in the first sliding portion 112 and be slidable relative to the first sliding portion 112 in a direction parallel to the second clamping surface 1121.

[0089] In some embodiments, the first main body portion 111 (e.g., the first support portion 1111) may be provided with a first accommodation cavity 1114. Opposite sidewalls of the first accommodation cavity 1114 may be provided with first sliding grooves 1115. The first extension portion 141 may be generally in the shape of a flat plate and have a first surface 1411. First sliding blocks 1412 may be provided at opposite sidewalls of the first extension portion 141. For example, the first sliding blocks 1412 may be columnar structures. The first extension portion 141 may be located in the first accommodation cavity 1114. The first surface 1411 may be coplanar with the first clamping surface 1113. The first sliding blocks 1412 may extend into the first sliding grooves 1115. The first extension portion 141 and the first main body portion 111 may achieve relative sliding through the first sliding blocks 1412 and the first sliding grooves 1115. The first surface 1411 and the first clamping surface 1113 may be jointly used to contact the lens L.

[0090] In some embodiments, the first sliding portion 112 may be provided with a second accommodation cavity 1122. Opposite sidewalls of the second accommodation cavity 1122 may be provided with second sliding grooves 1223. The second extension portion 142 may be generally in the shape of a flat plate and have a second surface 1421. Second sliding blocks 1422 may be provided at opposite sidewalls of the second extension portion 142. For example, the second sliding blocks 1422 may be generally columnar structures. The second extension portion 142 may be located in the second accommodation cavity 1122. The second surface 1421 may be coplanar with the second clamping surface 1121. The second sliding blocks 1422 may extend into the second sliding grooves 1123. The second extension portion 142 and the first sliding portion 112 may achieve relative sliding through the second sliding blocks 1422 and the second sliding grooves 1123. The second surface 1421 and the second clamping surface 1121 may be jointly used to contact the lens L.

[0091] It should be noted that the sliding connection between the first extension portion 141 and the first main body portion 111 is not limited to being achieved through the first sliding grooves 1115 and the first sliding blocks 1412. The first sliding grooves 1115 may be replaced by sliding rails. In addition, the installation positions of the sliding rails and the first sliding blocks 1412 may also be replaced. For example, the sliding rails may be provided on the first extension portion 141, and the first sliding blocks 1412 may be provided on the first main body portion 111. Without departing from the teachings of the present application, the sliding connection between the first extension portion 141 and the first main body portion 111 may be achieved by any sliding connection means known to those of ordinary skill in the art. Similarly, the sliding connection between the second extension portion 142 and the first sliding portion 112 is not limited to being achieved through the second sliding grooves 1123 and the second sliding blocks 1422. The second sliding grooves 1123 may be replaced by sliding rails. In addition, the installation positions of the sliding rails and the second sliding blocks 1422 may also be replaced. For example, the sliding rails may be provided on the second extension portion 142, and the second sliding blocks 1422 may be provided on the first sliding portion 112. Without departing from the teachings of the present application, the sliding connection between the second extension portion 142 and the first sliding portion 112 may be achieved by any sliding connection means known to those of ordinary skill in the art.

[0092] In some embodiments, at least one of the first main body portion 111 and the first extension portion 141 may be provided with a damper or a limiting member. For example, as described above, when the first main body portion 111 and the first extension portion 141 are slidably connected by a slide rail and a slider, the slide rail may be implemented as a damping slide rail or a limiting slide rail. Similarly, at least one of the first sliding portion 112 and the second extension portion 142 may be provided with a damper or a limiting member. For example, as described above, when the first sliding portion 112 and the second extension portion 142 are slidably connected by a slide rail and a slider, the slide rail may be implemented as a damping slide rail or a limiting slide rail. In this embodiment, by providing the damper and the limiting member, feedback can be provided during the manual adjustment of the first extension portion 141 and the second extension portion 142, which is beneficial to improving the adjustment accuracy.

[0093] Before the lens L is clamped by the first clamping mechanism 110, the relative position of the first extension portion 141 with respect to the first main body portion 111 and the relative position of the second extension portion 142 with respect to the first sliding portion 112 may be adjusted first. Thus, the first extension portion 141 and the second extension portion 142 help to expand the contact area between the first clamping mechanism 110 and the lens L. From another perspective, the first extension portion 141 and the second extension portion 142 help to expand the distance of the contact position with the lens L relative to the first mounting guide portion 113. For example, when the relative positions of the first mounting guide portion 113 and the lens L are fixed, it is possible to ensure the clamping of the lens L with a smaller size.

[0094] In some embodiments, as Figure 5 and Figure 7 shown, the lens clamping assembly 100 may further include a third extension portion 143 and a fourth extension portion 144. The third extension portion 143 may be embedded in the second main body portion 121 and be slidable relative to the second main body portion 121 in a direction parallel to the third clamping surface 1213. The fourth extension portion 144 may be embedded in the second sliding portion 122 and be slidable relative to the second sliding portion 122 in a direction parallel to the fourth clamping surface 1221.

[0095] In some embodiments, the second main body portion 121 (e.g., the second support portion 1211) may be provided with a third accommodation cavity 1214. Opposite side walls of the third accommodation cavity 1214 may be provided with third sliding grooves 1215. The third extension portion 143 may be generally in the shape of a flat plate and have a third surface 1431. Third sliding blocks 1432 may be provided at opposite side walls of the third extension portion 143. For example, the third sliding blocks 1432 may be columnar structures. The third extension portion 143 may be located in the third accommodation cavity 1214. The third surface 1431 may be coplanar with the third clamping surface 1213. The third sliding blocks 1432 may extend into the third sliding grooves 1215. The third extension portion 143 and the second main body portion 121 may achieve relative sliding through the third sliding blocks 1432 and the third sliding grooves 1215. The third surface 1431 and the third clamping surface 1213 may be jointly used to contact the lens L.

[0096] In some embodiments, the second sliding portion 122 may be provided with a fourth accommodation cavity 1222. Opposite side walls of the fourth accommodation cavity 1222 may be provided with fourth sliding grooves 1223. The fourth extension portion 144 may be generally in the shape of a flat plate and have a fourth surface 1441. Fourth sliding blocks 1442 may be provided at opposite side walls of the fourth extension portion 144. For example, the fourth sliding blocks 1442 may be generally columnar structures. The fourth extension portion 144 may be located in the fourth accommodation cavity 1222. The fourth surface 1441 may be coplanar with the fourth clamping surface 1221. The fourth sliding blocks 1442 may extend into the fourth sliding grooves 1223. The fourth extension portion 144 and the second sliding portion 122 may achieve relative sliding through the fourth sliding blocks 1442 and the fourth sliding grooves 1223. The fourth surface 1441 and the fourth clamping surface 1221 may be jointly used to contact the lens L.

[0097] It should be noted that the sliding connection between the third extension portion 143 and the second main body portion 121 is not limited to being achieved through the third sliding grooves 1215 and the third sliding blocks 1432. The third sliding grooves 1215 may be replaced with slide rails. In addition, the installation positions of the slide rails and the third sliding blocks 1432 may also be replaced. For example, the slide rails may be provided on the third extension portion 143, and the third sliding blocks 1432 may be provided on the second main body portion 121. Without departing from the teachings of the present application, the sliding connection between the third extension portion 143 and the second main body portion 121 may be achieved by any sliding connection means known to those of ordinary skill in the art. Similarly, the sliding connection between the fourth extension portion 144 and the second sliding portion 122 is not limited to being achieved through the fourth sliding grooves 1223 and the fourth sliding blocks 1442. The fourth sliding grooves 1223 may be replaced with slide rails. In addition, the installation positions of the slide rails and the fourth sliding blocks 1442 may also be replaced. For example, the slide rails may be provided on the fourth extension portion 144, and the fourth sliding blocks 1442 may be provided on the second sliding portion 122. Without departing from the teachings of the present application, the sliding connection between the fourth extension portion 144 and the second sliding portion 122 may be achieved by any sliding connection means known to those of ordinary skill in the art.

[0098] In some embodiments, at least one of the second main body portion 121 and the third extension portion 143 may be provided with a damper or a limiting member. For example, as described above, when the second main body portion 121 and the third extension portion 143 are slidably connected through a slide rail and a slider, the slide rail may be implemented as a damping slide rail or a limiting slide rail. Similarly, at least one of the second sliding portion 122 and the fourth extension portion 144 may be provided with a damper or a limiting member. For example, as described above, when the second sliding portion 122 and the fourth extension portion 144 are slidably connected through a slide rail and a slider, the slide rail may be implemented as a damping slide rail or a limiting slide rail. In this embodiment, by providing the damper and the limiting member, feedback can be provided during the manual adjustment of the third extension portion 143 and the fourth extension portion 144, which is beneficial to improving the adjustment accuracy.

[0099] Before the lens L is clamped by the second clamping mechanism 120, the relative position of the third extension portion 143 with respect to the second main body portion 121 and the relative position of the fourth extension portion 144 with respect to the second sliding portion 122 may be adjusted first. Thus, the third extension portion 143 and the fourth extension portion 144 help to expand the contact area between the second clamping mechanism 120 and the lens L. From another perspective, the third extension portion 143 and the fourth extension portion 144 help to expand the distance between the contact position with the lens L and the second mounting guide portion 123. For example, when the relative positions of the second mounting guide portion 123 and the lens L are fixed, it is possible to ensure the clamping of the lens L with a smaller size.

[0100] Some embodiments of the present application also provide a near-eye display device. Figure 8 It is a three-dimensional schematic diagram of the near-eye display device provided by the embodiments of the present application. For example, the near-eye display device 200 may be an AR glasses.

[0101] Such as Figures 1 to 3 and Figure 8As shown, the near-eye display device 200 may include a spectacle frame 150, a first clamping mechanism 110, and a second clamping mechanism 120. The spectacle frame 150 may include a spectacle frame body 151, a first mounting and mating portion 152, and a second mounting and mating portion 153. The first mounting and mating portion 152 and the second mounting and mating portion 153 may be disposed inside the spectacle frame body 151 and are oppositely arranged. The first clamping mechanism 110 may include a first main body portion 111, a first sliding portion 112, and a first mounting guide portion 113. The first sliding portion 112 is slidable relative to the first main body portion 111 to clamp the lens. The first mounting guide portion 113 may be disposed on the first main body portion 111. The second clamping mechanism 120 may include a second main body portion 121, a second sliding portion 122, and a second mounting guide portion 123. The second sliding portion 122 is slidable relative to the second main body portion 121 to clamp the lens L. The second mounting guide portion 123 may be disposed on the second main body portion 121. The first mounting guide portion 113 is fixedly connected to the first main body portion 111, the second mounting guide portion 123 is detachably connected to the second main body portion 121, and the first mounting guide portion 113 is detachably connected to the first mounting and mating portion 152, and the second mounting guide portion 123 is detachably connected to the second mounting and mating portion 153.

[0102] For the near-eye display device 200 provided according to the above embodiment, the first main body portion 111 and the first sliding portion 112 in the first clamping mechanism 110, and the second main body portion 121 and the second sliding portion 122 in the second clamping mechanism 120 jointly clamp the single-piece lens L. The first mounting guide portion 113 is fixedly connected to the first main body portion 111 and the second mounting guide portion 123 is detachably connected to the second main body portion 121, which can enable the first mounting guide portion 113 and the second mounting guide portion 123 to be detachably connected to the spectacle frame 150 conveniently, contributing to the flexible disassembly and assembly of the lens L. In addition, the first clamping mechanism 110 and the second clamping mechanism 120 occupy a small space, and the lens L does not need to be customized additionally, which helps to improve the adaptability of the lens L.

[0103] In some embodiments, the spectacle frame body 151 may include a left spectacle frame body 1511 and a right spectacle frame body 1512. A set of first mounting and mating portions 152l and second mounting and mating portions 153l may be disposed inside the left spectacle frame body 1511 and are oppositely arranged. Another set of first mounting and mating portions and second mounting and mating portions (not shown) may be disposed inside the right spectacle frame body 1512 and are oppositely arranged.

[0104] Here, a set of first mounting and mating portions 152l and second mounting and mating portions 153l are taken as an example for illustration.

[0105] In some embodiments, such as Figure 1 , Figure 2 and Figure 8As shown, the first installation mating part 152l can be implemented as a first groove, and the first installation guiding part 113 can be implemented as a protrusion. The first installation guiding part 113 is integrally formed with the first main body part 111. For example, along the depth direction of the first groove, its cross-sectional dimension is equal to or smaller than that of the protrusion. When the cross-sectional dimension of the first groove is smaller than that of the protrusion, an interference fit connection can be achieved between the first installation guiding part 113 and the first installation mating part 152l, thereby preventing the first clamping mechanism 110 from loosening.

[0106] In some embodiments, when the first installation mating part 152l is implemented as a first groove and the first installation guiding part 113 is implemented as a protrusion, one side of the protrusion can have a chamfer. Correspondingly, the cross-sectional shapes of the first groove and the protrusion are the same. Setting the first installation guiding part 113 to have a single-sided chamfer makes the protrusion have a non-planar symmetric shape, which plays an anti-mistake role when it is installed with the first installation mating part 152l.

[0107] In some embodiments, as Figure 1 , Figure 3 and Figure 8 shown, the second installation mating part 153l can be implemented as a second groove. The second main body part 121 is provided with an installation groove 128. The first part of the second installation guiding part 123 extends into the installation groove 128, and the second part of the second installation guiding part 123 extends into the second groove. The second installation guiding part 123 can be made of an elastic material. In other words, the second installation guiding part 123 is detachably connected to the second main body part 121 and the spectacle frame 151 respectively. For example, along the depth direction of the second groove, its cross-sectional dimension is approximately equal to that of the second installation guiding part 123. For example, the dimensional tolerance between the cross-sectional dimensions of the second groove and the second installation guiding part 123 is within the range of ±0.05. Thus, the second installation mating part 153l and the second installation guiding part 123 can balance the requirements of being cheap to disassemble and assemble and having a firm connection.

[0108] In some embodiments, the second part of the second installation guiding part 123 is trapezoidal. The cross-sectional shape of the above-mentioned second groove is the same as that of the second part, that is, the cross-sectional shape of the second groove is also trapezoidal. In this embodiment, the cross-sectional shapes of the second part of the second installation guiding part 123 and the second groove are both trapezoidal, which can play a guiding role during the installation process, facilitate the installation, and can also ensure the connection firmness.

[0109] In some embodiments, as Figure 2 and Figure 3As shown, the first main body portion 111 has a first clamping surface 1113, the first sliding portion 112 has a second clamping surface 1121, and the first clamping surface 1113 and the second clamping surface 1121 are arranged opposite to each other and are used to contact the lens L. The second main body portion 121 has a third clamping surface 1213, the second sliding portion 122 has a fourth clamping surface 1221, and the third clamping surface 1213 and the fourth clamping surface 1221 are arranged opposite to each other and are used to contact the lens L.

[0110] In some embodiments, the first sliding portion 112 is provided with a first guiding member 116, the first main body portion 111 is provided with a first guiding hole 114, and the first guiding member 116 extends into the first guiding hole 114 to slide in a direction perpendicular to the first clamping surface 1113. The second sliding portion 122 is provided with a second guiding member 126, the second main body portion 121 is provided with a second guiding hole 124, and the second guiding member 126 extends into the second guiding hole 124 to slide in a direction perpendicular to the third clamping surface 1213.

[0111] In some embodiments, a buffer pad 131 may be provided on at least one of the first clamping surface 1113, the second clamping surface 1121, the third clamping surface 1213, and the fourth clamping surface 1221. The buffer pad 131 may be made of an elastic material.

[0112] In some embodiments, as Figures 5 to 7 shown, the near-eye display device 200 may further include a first extension portion 141 and a second extension portion 142. The first extension portion 141 may be embedded in the first main body portion 111 and is slidable relative to the first main body portion 111 in a direction parallel to the first clamping surface 1113. The second extension portion 142 may be embedded in the first sliding portion 112 and is slidable relative to the first sliding portion 112 in a direction parallel to the second clamping surface 1121.

[0113] In some embodiments, the near-eye display device 200 may further include a third extension portion 143 and a fourth extension portion 144. The third extension portion 143 may be embedded in the second main body portion 121 and is slidable relative to the second main body portion 121 in a direction parallel to the third clamping surface 1213. The fourth extension portion 144 may be embedded in the second sliding portion 122 and is slidable relative to the second sliding portion 122 in a direction parallel to the fourth clamping surface 1221.

[0114] In some embodiments, at least one of the first main body portion 111 and the first extension portion 141 and at least one of the first sliding portion 112 and the second extension portion 142 are provided with a damper or a limiting member. At least one of the second main body portion 121 and the third extension portion 143 and at least one of the second sliding portion 122 and the fourth extension portion 144 are provided with a damper or a limiting member.

[0115] Figure 9It is a three-dimensional schematic diagram of the near-eye display device 200 provided by another embodiment of the present application. For the purpose of concise description, the same content as the previous embodiment will not be repeated in this application. For example, in this embodiment, the first clamping mechanism, the frame body, and the first installation and mating parts are the same as the corresponding components in the previous embodiment, and will not be repeated here.

[0116] Still taking a group of the first installation and mating parts 152l and the second installation and mating parts 153l’ as an example for illustration below.

[0117] In some embodiments, such as Figure 4 and Figure 9 shown, the second installation and mating part 153l’ can be implemented as a through hole. The second main body part 121 can be provided with an installation positioning hole 129. At least part of the outer surface of the second installation guiding part 123’ can be provided with threads, and a part of the second installation guiding part 123’ extends into the installation positioning hole 129, and another part of the second installation guiding part 123’ extends into the through hole. For example, the second installation and mating part 153l’ can be implemented as a threaded through hole. The second installation guiding part 123’ can be implemented as a stud. The stud passes through the threaded through hole and extends into the installation positioning hole 129, and the stud is locked with the threaded through hole and abuts against the installation positioning hole 129 to realize the detachable connection between the second clamping mechanism 120 and the frame 150.

[0118] The above description is only the preferred embodiment of the present application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
