If a first acting element and a second acting element are disposed on a side of the eyewear device 1 facing the observation eyes of the wearer, the first acting element and the second acting element are magnetically attracted to attach the eyewear device 2 to the eyewear device 1.

In addition, referring to fig. 3 and 4, the present embodiment further provides a vision adapter 2, which includes at least one lens frame 21 and a lens 22, wherein at least a portion of an outer contour of the lens 22 matches with an inner contour of the lens frame 21, a clamping structure is disposed between the lens frame 21 and the lens 22, and the clamping structure clamps the lens 22 in the lens frame 21.

Because the outline of lens 22 has at least partly and the interior profile phase-match of lens frame 21, and be equipped with the joint structure between lens frame 21 and the lens 22, joint structure is with lens 22 joint in lens frame 21, the joint structure makes at least partly contact with the interior profile of lens frame 21 on the outline of lens 22, the stability of lens 22 has been guaranteed, secondly, because the observation eye number of degrees between the wearer is different, or the number of degrees of left observation eye and the right observation eye of wearer is different, it is also different to lead to the lens 22 that matches with lens frame 21, be equipped with the joint structure between lens frame 21 and lens 22, convenient dismantlement, lens frame 21 can hold the lens 22 of different numbers, the wearer can change the lens 22 with the adaptation of own eye number of degrees according to own eye number of degrees, need not to make many pairs of lens frames 21 and lens 22, the purpose that a pair of lens frame 21 can be equipped with the lens 22 of multiple different numbers of degrees has been realized, make lens frame 21 have the commonality.

The vision adapter 2 includes at least one lens frame 21, that is, one or two lens frames 21, and when one lens frame 21 is provided, one or two lens elements 22 may be provided, which is not limited in this application. When there are two lens frames 21, there are two corresponding lenses 22. It should be added that the lens 22 is one, and when the vision adapter 2 is mounted on the side of the eyewear device 1 facing the viewing eye of the wearer, the lens 22 has a coverage area equal to or larger than the coverage area of the viewing eye of the wearer.

Because there are different possibilities in the eyesight of the left observation eye and the right observation eye of the wearer, in order to adapt the eyesight of the wearer, in an implementation of the present application, two lenses 22 are selected for use, and the power of the two lenses 22 is adapted to the eyesight of the left observation eye and the right observation eye of the wearer, respectively, so as to obtain clear imaging in the observation eyes of the wearer.

Specifically, the lens 22 may be a near-vision lens 22 or a far-vision lens 22, the near-vision lens 22 is suitable for being used in the near-vision condition of the observation eye of the wearer, the far-vision lens 22 is suitable for being used in the far-vision condition of the observation eye of the wearer, and the type of the lens 22 may be selected according to the specific condition of the observation eye of the wearer, which is not limited in this application.

It should be added that at least a part of the outer contour of the lens 22 matches with the inner contour of the lens frame 21, and the relative shapes of the outer contour of the lens 22 and the lens frame 21 are not limited herein, and it is only necessary to ensure that at least a part of the outer contour of the lens 22 matches with the inner contour of the lens 22. For example, the lens 22 may have an oval structure, and the lens frame 21 may have a square structure, wherein a part of the outer contour of the oval structure matches with the inner contour of the square structure; if the lens 22 is a square structure and the lens frame 21 is a prismatic structure, a part of the outer contour of the square structure matches with the inner contour of the prismatic structure; for another example, the lens 22 has a prismatic structure, the lens frame 21 has an elliptical structure, and a part of the outer contour of the prismatic structure matches with the inner contour of the elliptical structure. Of course, the lens 22 and the lens frame 21 may have other structures so that a part of the outer contour of the lens 22 matches the inner contour of the lens frame 21.

The above-mentioned embodiments are all the cases where a part of the outer contour of the lens 22 matches the inner contour of the lens frame 21, but of course, the outer contour of the lens 22 may completely match the inner contour of the lens frame 21. For example, both the lens 22 and the lens frame 21 may have an oval structure; for example, the lens 22 and the lens frame 21 may have a square structure; for another example, the lens 22 and the lens frame 21 may have prismatic structures, so that the outer contour of the lens 22 can be completely matched with the inner contour of the lens frame 21. It should be added that the lens 22 and the lens frame 21 may have other structures, and the application is not limited thereto.

In addition, a clamping structure is arranged between the lens frame 21 and the lens 22, and the lens 22 is clamped in the lens frame 21 by the clamping structure. If the lens 22 is completely engaged with the lens frame 21, the displacement between the lens frame 21 and the lens 22 in three directions is limited. Displacement of the lens 22 along the radial direction of the lens frame 21; displacement of the lens 22 along the circumferential direction of the lens frame 21; the lens 22 is displaced in the axial direction of the lens frame 21. It should be added that the number of the clamping structures may be one to limit the displacement in three directions, or may be three to limit the displacement in three directions, which is not limited in the present application. In an implementation of this application, the joint structure includes threely to respectively restrict the displacement of three direction, so, can conveniently dismantle the lens.

Of course, referring to fig. 5, the lens frame 21 may be a closed structure or a non-closed structure, and therefore, the present application is not limited thereto, when the lens frame 21 is a closed structure, the lens 22 needs to be installed axially from the lens frame 21, the lens 22 is easily scratched during the operation process, and the operation difficulty is large. The lens frame 21 is configured to be a non-closed structure, and the lens 22 can be installed from the non-closed position of the lens frame 21, so that the operation is convenient, and the lens 22 is not easy to scratch. In one implementation of the present application, lens frame 21 is a non-enclosed structure having opening 211.

The lens frame 21 is a non-closed structure having an opening 211, for example, the opening 211 is disposed above the lens frame 21, and the lower outer contour of the lens 22 matches the inner contour of the lens frame 21, so as to clamp the lens 22 in the lens frame 21; if the opening 211 is disposed below the lens frame 21, the upper outer contour of the lens 22 matches with the inner contour of the lens frame 21, so as to clip the lens 22 into the lens frame 21. Of course, the opening 211 may be disposed at other positions of the lens frame 21, and the application is not limited thereto.

Since the lens frame 21 is a non-closed structure having the opening 211, when at least a portion of the outer contour of the lens 22 matches the inner contour of the lens frame 21, the lens 22 is displaced along the opening 211 of the lens frame 21 relative to the lens frame 21 during use, that is, the lens 22 is displaced in a radial direction relative to the lens frame 21. Therefore, the clamping structure includes a clamping portion 212 disposed at the opening 211, and the clamping portion 212 abuts against an outer contour of the lens 22 to limit the displacement of the lens 22 along the opening 211 of the lens frame 21.

The clip portion 212 is slidably connected to the lens frame 21, or may be fixedly connected to the lens frame, which is not limited in this application. When the clamping portion 212 is slidably connected to the lens frame 21, a sliding groove is formed in the lens frame 21 in a direction away from the opening 211, the clamping portion 212 is provided with a sliding rib, and the sliding groove is matched with the sliding rib in a protruding manner. When the lens frame 21 needs to mount or dismount the lens 22, the clamping portion 212 slides in a direction away from the opening 211, at least a part of the outer contour of the lens 22 matches with the inner contour of the lens frame 21, then the clamping portion 212 moves in a direction close to the opening 211, and the clamping portion 212 abuts against the outer contour of the lens 22 to limit the displacement of the lens 22 in the direction of the opening 211 of the lens frame 21. For example, when the clip portion 212 is fixedly connected to the lens frame 21, the clip portion 212 may be made of a material having a certain elastic deformation. When lens 22 needs to be installed or disassembled, the wearer only needs to apply certain external force, so that the clamping portion 212 generates certain deformation along the direction away from the opening 211, and therefore the lens 22 can be conveniently and quickly replaced by the wearer, and time is saved.

On this basis, the clamping portion 212 may be one, and it is only required to be disposed at one end of the opening 211 of the lens frame 21, or may be symmetrically disposed at two ends of the opening 211 of the lens frame 21, and thus, the present application is not limited thereto. However, if one of the clamping portions 212 is provided, the visual adapter 2 needs to keep the opening 211 of the lens frame 21 facing upward at any time, and if the opening 211 of the lens frame 21 faces other directions, the side of the opening 211 without the clamping portion 212 does not abut against the outer contour of the lens 22, and at this time, the lens 22 may shake along the direction of the opening 211 of the lens frame 21, which is difficult to keep stable. Preferably, two clamping portions 212 are selected, and the clamping portions 212 are symmetrically arranged at two ends of the opening 211 of the lens frame 21.

In order to avoid the stress concentration at opening 211 of lens frame 21, prevent that joint 212 from splitting from opening 211 of lens frame 21, set up the interior profile of opening 211 department of lens frame 21 into the arc, so, can make things convenient for the stress of lens frame 21 to pass through gradually, reduce gradually, and set up to the arc, also make things convenient for the cleanness of opening 211 department of lens frame 21.

In some embodiments provided herein, the clamping structure may limit the displacement of the lens 22 along the circumferential direction of the lens frame 21 in addition to the displacement of the lens 22 along the direction of the opening 211 of the lens frame 21. Therefore, the clamping structure includes a first clamping groove 221 formed in the inner side of the lens frame 21 at the first rib position protrusion 213 and the outer side of the lens 22 corresponding to the first rib position protrusion 213, or a first clamping groove 221 formed in the inner side of the lens frame 21 at the first rib position protrusion 213 and the outer side of the lens 22 corresponding to the first clamping groove 221, wherein the first rib position protrusion 213 is clamped in the first clamping groove 221 to limit the circumferential displacement of the lens 22 along the lens frame 21. In an implementation manner provided by the present application, as shown in fig. 4, fig. 5 and fig. 6, the clamping structure includes a first rib protrusion 213 disposed on an inner side of the lens frame 21 and a first clamping groove 221 disposed on an outer side of the lens 22 corresponding to the first rib protrusion 213.

The first rib protrusion 213 disposed inside the lens frame 21 or the first engaging groove 221 disposed inside the lens frame 21 may extend along the axial direction of the inner contour of the lens frame 21, or may extend in a direction forming a certain acute angle with the axial direction of the inner contour of the lens frame 21. Similarly, the first clipping groove 221 disposed at a position corresponding to the first rib position protrusion 213 outside the lens 22 or the first rib position protrusion 213 disposed at a position corresponding to the first clipping groove 221 outside the lens 22 may extend along the axial direction of the outer contour of the lens 22, or may extend in a direction forming a certain acute angle with the axial direction of the outer contour of the lens 22, which is not limited in this application.

In an implementation manner provided by the present application, the axial extension of the first rib position protrusion 213 along the inner contour of the lens frame 21 or the axial extension of the first clamping groove 221 along the inner contour of the lens frame 21 can more effectively limit the displacement of the lens 22 along the circumferential direction of the lens frame 21. Similarly, the axial extension of the first locking groove 221 along the outer contour of the lens 22 or the axial extension of the first rib protrusion 213 along the outer contour of the lens 22 can also accurately limit the displacement of the lens 22 along the circumferential direction of the lens frame 21.

It should be added that the first rib protrusion 213 extends axially along the inner contour of the lens frame 21 or the first locking groove 221 extends axially along the inner contour of the lens frame 21, and may either extend through the inner contour of the lens frame 21 along the axial portion of the lens frame 21 or completely extend through the inner contour of the lens frame 21 along the axial direction of the lens frame 21, which is not limited in this application. That is, the length of the first rib protrusion 213 or the first engaging groove 221 is less than or equal to the thickness of the lens frame 21.

Similarly, the first engaging groove 221 or the first rib protrusion 213 may extend along the axial direction of the outer contour of the lens 22, or may extend along the axial direction of the outer contour of the lens 22 to penetrate the outer contour of the lens 22 along the axial portion of the lens 22, or may completely penetrate the outer contour of the lens 22 along the axial direction of the lens 22, which is not limited in this application. That is, the length of the first engaging groove 221 or the first rib protrusion 213 is less than or equal to the thickness of the lens 22.

In addition, the first rib protrusion 213 or the first snap groove 221, which is disposed along the axial extension of the inner contour of the lens frame 21, may be disposed at a position of the lens frame 21 close to the opening 211, or may be disposed at a position of the lens frame 21 away from the opening 211, which is not limited in this application. In an implementation manner of the present application, the first rib protrusion 213 or the first fastening groove 221 is disposed at a position of the lens frame 21 close to the opening 211.

In other embodiments provided in the present application, referring to fig. 4, 5 and 6, in addition to limiting the displacement of the lens 22 along the opening 211 of the lens frame 21 and the displacement of the lens 22 along the circumferential direction of the lens frame 21, the clamping structure can also limit the displacement of the lens along the axial direction of the lens frame 21, therefore, the clamping structure includes a second rib position protrusion 214 disposed on the inner side of the lens frame 21 and a second clamping groove 222 disposed on the outer side of the lens 22 corresponding to the second rib position protrusion 214, or the second clamping groove 222 disposed on the inner side of the lens frame 21 and a second rib position protrusion 214 disposed on the outer side of the lens 22 corresponding to the second clamping groove 222, and the second rib position protrusion 214 is clamped in the second clamping groove 222 to limit the displacement of the lens 22 along the axial direction of the lens frame 21. In an implementation manner provided by the present application, referring to fig. 4, 5 and 6, the clamping structure includes a second rib protrusion 214 disposed on the inner side of the lens frame 21 and a second clamping groove 222 disposed on the outer side of the lens 22 corresponding to the second rib protrusion 214.

The second rib protrusions 214 disposed on the inner side of the lens frame 21 or the second snap grooves 222 disposed on the inner side of the lens frame 21 may extend along the circumferential direction of the inner contour of the lens frame 21, or may extend along a direction forming a certain acute angle with the circumferential direction of the inner contour of the lens frame 21. Similarly, the second clipping groove 222 disposed at a position corresponding to the second rib position protrusion 214 outside the lens 22 or the second rib position protrusion 214 disposed at a position corresponding to the second clipping groove 222 outside the lens 22 may extend along the circumferential direction of the outer contour of the lens 22, or may extend in a direction forming a certain acute angle with the circumferential direction of the outer contour of the lens 22, which is not limited in this application.

In an implementation manner provided by the present application, the second rib position protrusion 214 extends along the circumferential direction of the inner contour of the lens frame 21 or the second clamping groove 222 extends along the circumferential direction of the inner contour of the lens frame 21 to more effectively limit the axial displacement of the lens 22 along the lens frame 21. Similarly, the second locking groove 222 or the second rib protrusion 214 circumferentially extends along the outer contour of the lens 22 can further effectively limit the displacement of the lens 22 along the axial direction of the lens frame 21.

It should be added that the second rib protrusions 214 extend along the circumferential direction of the inner contour of the lens frame 21 or the second fastening grooves 222 extend along the circumferential direction of the inner contour of the lens frame 21, and may both partially penetrate the inner contour of the lens frame 21 along the circumferential direction of the lens frame 21 and completely penetrate the inner contour of the lens frame 21 along the circumferential direction of the lens frame 21, which is not limited in this application.

In order to facilitate the processing and manufacturing and save the processing cost, in an implementation manner of the present application, the outer contour of the first rib position protrusion 213 is selected to be a regular structure such as a square structure, a triangular structure or a semi-circle, and correspondingly, the inner contour of the first snap-in groove 221 is also selected to be a regular structure such as a square structure, a triangular structure or a semi-circle, which is adapted to the first rib position protrusion 213.

Similarly, the second rib position protrusion 214 is clamped in the second clamping groove 222, an outer contour of the second rib position protrusion 214 is adapted to an inner contour of the second clamping groove 222, taking the second rib position protrusion 214 as an example, the outer contour of the second rib position protrusion 214 may be a regular structure such as a square structure, a triangular structure or a semicircular structure, or may be an irregular structure, which is not limited in this application. In order to facilitate the processing and manufacturing and save the processing cost, in an implementation manner of the present application, the outer contour of the second rib position protrusion 214 is selected to be a regular structure such as a square structure, a triangular structure or a semi-circle, and correspondingly, the inner contour of the second snap-in groove 222 is also selected to be a regular structure such as a square structure, a triangular structure or a semi-circle, which is adapted to the second rib position protrusion 214.

In addition, the second rib position protrusion 214 or the second snap groove 222 extending along the circumferential direction of the inner contour of the lens frame 21 may be disposed at a position of the lens frame 21 close to the opening 211, or may be disposed at a position of the lens frame 21 away from the opening 211, which is not limited in this application. In one implementation of the present application, the second rib protrusion 214 or the second locking groove 222 is disposed on the lens frame 21 near the opening 211.

Further, referring to fig. 4, 5 and 6, when the first rib position protrusion 213 and the second rib position protrusion 214 are disposed on the same one of the lens frame 21 and the lens 22, since the first rib position protrusion 213 is clamped in the first clamping groove 221, the lens 22 is restricted from moving along the circumferential direction of the lens frame 21, the second rib position protrusion 214 is clamped in the second clamping groove 222, the lens 22 is restricted from moving along the axial direction of the lens frame 21, and if the first rib position protrusion 213 is connected with the second rib position protrusion 214, it is inconvenient for the lens 22 to be detached. Therefore, in an implementation manner of the present application, an escape space 223 is provided between the first rib position protrusion 213 and the second rib position protrusion 214 to avoid facilitating the quick detachment of the lens 22.

The above description is only exemplary of the present invention and should not be construed as limiting the scope of the present invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
