[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0060] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0061] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0062] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0063] The present invention proposes a lens locking mechanism for connecting a frame and a lens. The lens locking mechanism can be used for smart glasses or ordinary glasses, wherein smart glasses include but are not limited to VR (Virtual Reality) glasses, AR (Augmented Reality) glasses, etc. Figures 1 to 5 In one embodiment of the present invention, the lens locking mechanism includes:

[0064] Base 10, for connecting to the frame 80;

[0065] A main buckle module is provided on the base 10. The main buckle module includes a main drive assembly 40 and a main buckle 20. The main buckle 20 can move between a locked position and an unlocked position to lock or unlock the lens 90. Under the drive of the main drive assembly 40, the main buckle 20 can at least move from the locked position to the unlocked position; and

[0066] The auxiliary buckle module is provided on the base 10 and includes an auxiliary buckle 30. The auxiliary buckle 30 can move between a check position and a release position to limit or release the limit connection with the main buckle 20 in the unlocked position.

[0067] In the technical solution of the present invention, the main buckle 20 is movable on the base 10 and has an unlocked position and a locked position. In the locked position, the main buckle 20 is locked and fixed to the lens 90, while in the unlocked position, the main buckle 20 is released from the locked position to unlock the lens 90. The auxiliary buckle 30 is also movable on the base 10 and has a check position and a release position. In the check position, the auxiliary buckle 30 is checkably connected to the main buckle 20 in the unlocked position, while in the release position, the auxiliary buckle 30 is released from the check position. When the main drive assembly 40 is subjected to an external operating force, the main buckle 20 can be moved from the locked position to the unlocked position. If the external operating force disappears, the main buckle 20 may accidentally return to the locked position. At this time, the auxiliary buckle 30 moves to the check position and is checkably connected to the main buckle 20 in the unlocked position. In other words, the auxiliary buckle 30 intervenes in the movement of the main buckle 20, thereby maintaining the main buckle 20 in the unlocked position even if the external operating force disappears. Therefore, after the user applies an operating force to the main drive assembly 40 to move the main buckle 20 to the unlocked position, the user can release the operating force on the main drive assembly 40, and the freed hand can more easily operate the removal, replacement, and installation of the lens 90. When the replaced lens 90 is assembled, the user can apply an operating force to the main drive assembly 40 again, or apply an operating force to the auxiliary buckle module to return the auxiliary buckle 30 to the unlocked position, so that the main buckle 20 can be driven by the main drive assembly 40 to return to the locked position, and the lens 90 can be locked and fixed again.

[0068] In the technical solution of the present invention, the main buckle 20 is restricted to the unlocked position by the auxiliary buckle 30, avoiding the problem of the main buckle 20 accidentally resetting to the locked position and interfering with the removal and installation of the lens 90, thereby freeing the user's hands so that the user can remove and install the lens 90 more calmly and conveniently, thereby improving the operational convenience of loading and unloading the lens 90 and enhancing the user experience.

[0069] In some embodiments, the main drive assembly 40 includes a main drive component 41 and a main drive reset component 42. The main buckle 20 can be moved from the locked position to the unlocked position under the drive of the main drive component 41, and the main buckle 20 can be moved toward the locked position under the action of the main drive reset component 42. That is, under the drive of the main drive reset component 42, the main buckle 20 can also move from the unlocked position to the locked position. In this way, when the auxiliary buckle 30 is released from the limiting connection with the main buckle 20 in the unlocked position, the main buckle 20 can be automatically reset to the locked position under the action of the main drive reset component 42, thereby facilitating the operation of locking the lens 90 and improving operational convenience. Of course, in other embodiments, the main drive reset member 42 may not be provided. After the auxiliary buckle 30 is released from the limiting connection with the main buckle 20 in the unlocked position, the user can apply operating force to the main drive member 41 again to enable the main buckle 20 to move from the unlocked position to the locked position. Although the main buckle 20 is not affected by the main drive reset member 42 at this time, it may also automatically reset to the locked position and interfere with the disassembly and assembly of the lens 90 due to factors such as gravity and loose fit with the base 10. Therefore, it is still necessary to provide an auxiliary buckle 30 to limit the main buckle 20 in the unlocked position.

[0070] Please refer to Figures 4 to 9 In some embodiments, the main drive component 41 is provided with a main drive inclined surface 41a, and the main buckle 20 is provided with a first inclined surface 20a corresponding to the main drive inclined surface 41a. The first inclined surface 20a slides against the main drive inclined surface 41a, so that when the main drive component 41 moves in the second direction, it can prompt the main buckle 20 to move in the first direction, and the first direction and the second direction intersect. In this way, the main drive inclined surface 41a cooperates with the first inclined surface 20a to achieve the reversing transmission of displacement, which can make the structure of the main buckle module and the auxiliary buckle module compact and occupy a small volume. Of course, in other embodiments, the main drive component 41 and the main buckle 20 can also be rigidly connected and move in the same direction.

[0071] In some embodiments, the main drive reset member 42 includes a first elastic member 421, which connects the main buckle 20 and the base 10 and can be elastically deformed along the first direction so that the main buckle 20 has a tendency to move toward the locked position. It can be understood that the force of the first elastic member 421 can not only reset the main buckle 20 to the locked position, but also be transmitted to the main drive member 41 through the matching structure of the first inclined surface 20a and the main drive inclined surface 41a, so that the main drive member 41 is also reset to the main drive starting position. It should be noted that the main drive member 41 moves along the second direction and has a main drive starting position and a main drive second position, which correspond to the locked position and unlocked position of the main buckle 20 respectively.

[0072] The main drive reset member 42 also includes a second elastic member 422, which connects the main drive member 41 and the base 10 and can be elastically deformed along the second direction, so that the main drive member 41 has a tendency to move in the direction away from the main buckle 20. In this way, the force of the second elastic member 422 can act directly on the main drive member 41, so that when the auxiliary buckle 30 releases the limit on the main buckle 20, the main drive member 41 and the main buckle 20 can be reset to the main drive starting position and the locking position more smoothly, respectively. Specifically, optionally, the first elastic member 421 and the second elastic member 422 are both configured as compression springs. Of course, in other embodiments, at least one of the first elastic member 421 and the second elastic member 422 can be configured as a metal shrapnel, an elastic rubber body or an elastic silicone body. In some other embodiments, the second elastic member 422 may not be provided.

[0073] Please refer to Figure 3 In some embodiments, the base 10 is provided with a mounting cavity 11, a first through hole 12 and a second through hole 13 both communicating with the mounting cavity 11, the main buckle module and the auxiliary buckle module are at least partially accommodated in the mounting cavity 11, one end of the main buckle 20 is provided with the first through hole 12 to achieve locking of the lens 90, and one end of the main drive component 41 is provided with the second through hole 13 for pushing operation. In this way, by accommodating most of the structures of the main buckle module and the auxiliary buckle module in the mounting cavity 11, good protection and dustproof effects can be achieved, thereby improving the operational stability and service life of the lens 90 locking mechanism. Of course, in other embodiments, the main buckle module and / or the auxiliary buckle module can also be arranged on the outside of the base 10.

[0074] Please refer to Figures 3 to 9 In order to facilitate the installation of the first elastic member 421, in some embodiments, the installation cavity 11 includes a main buckle slide section 111 connected to the first through hole 12, and the main buckle 20 is slidably arranged in the main buckle slide section 111. The main buckle 20 is provided with a tail end hole 20b on the end face away from the first through hole 12, one end of the first elastic member 421 is inserted into the tail end hole 20b, and the other end abuts against the end wall of the main buckle slide section 111.

[0075] In some embodiments, the lens 90 locking mechanism further includes a bottom cover 60 positioned over the opening of the mounting cavity 11. The bottom cover 60 includes a first guide post 61 projecting toward the main drive component 41. A second elastic member 422 is sleeved onto the first guide post 61, with one end abutting the bottom cover 60 and the other end abutting the main drive component 41. This facilitates installation of the second elastic member 422. Specifically, the bottom cover 60, the first guide post 61, and the housing 81 of the frame 80 are optionally integrally formed. This simplifies the structure of the smart glasses and reduces their weight and manufacturing cost. Of course, in other embodiments, the bottom cover 60 may also include a guide cylinder, into which the second elastic member 422 is movably inserted. In yet other embodiments, the bottom cover 60 and the housing 81 of the frame 80 are separate components, and / or the first guide post 61 is separate from the bottom cover 60; or the bottom cover 60 and the housing 81 of the frame 80 are integrally formed, with the first guide post 61 separate from the bottom cover 60.

[0076] It is worth mentioning that in the embodiment where the bottom cover 60 and the frame 80 are integrally formed, the base 10, the main buckle module, and the auxiliary buckle module can optionally be assembled as a whole. That is, these three can be assembled together off the production line and then sent to the production line to be mounted and fixed to the frame 80, thereby improving production efficiency on the production line. Of course, in other embodiments, the base 10 and / or the main buckle module and / or the auxiliary buckle module can also be assembled separately to the frame 80.

[0077] In some embodiments, the base 10 is screwed to the frame housing 81 of the frame 80. Specifically, the base 10 is provided with screw holes 14 on opposite sides, and the frame 80 is provided with corresponding threaded holes 84, through which screws can pass and connect.

[0078] In some embodiments, the main buckle 20 is provided with a relief hole 20c corresponding to the second elastic member 422. The relief hole 20c extends along the first direction, and the second elastic member 422 is at least partially located within the relief hole 20c. This allows for a more compact structure of the main buckle module and the auxiliary buckle module, occupying a smaller volume of the mounting cavity 11. Furthermore, the force exerted by the second elastic member 422 on the main drive member 41 is more centered and stable, thereby improving the smooth operation of the main drive member 41. Of course, in other embodiments, two second elastic members 422 may be provided, one on each opposite side of the main buckle 20.

[0079] In some embodiments, the secondary buckle module further includes a secondary drive assembly 50, which is used to drive the secondary buckle 30 between a non-return position and a release position. Thus, by applying an operating force to the secondary drive assembly 50 to return the secondary buckle 30 to the release position, the release operation of the secondary buckle 30 can be performed more effortlessly, thereby improving operational convenience. Of course, in some other embodiments, the auxiliary drive component 50 may not be provided. For example, the auxiliary buckle 30 is configured as a buckle that can be elastically deformed. When the main buckle 20 moves toward the unlocked position, the buckle is forced to undergo elastic deformation, and is elastically reset when it reaches the unlocked position and is limited and fixed by the buckle. Then, an operating force that can overcome the buckle resistance is applied to the main drive component 40 to disengage the main buckle 20 from the limited engagement of the auxiliary buckle 30, and the main buckle 20 can automatically reset to the locked position to complete the locking and fixation of the lens 90; that is, the buckle as the auxiliary buckle 30 uses the elastic deformation of its own structure under the force applied by the main buckle 20 to achieve movement between the check position and the unlocked position without the need for an additional auxiliary drive component 50.

[0080] In some embodiments, the secondary drive assembly 50 includes a secondary drive member 51 and a secondary drive reset member 52. The secondary buckle 30 is capable of moving toward a non-return position under the action of the secondary drive reset member 52. Driven by the secondary drive member 51, the secondary buckle 30 is capable of moving from the non-return position toward a released position. In other words, driven by the secondary drive reset member 52, the secondary buckle 30 is also capable of moving from the released position to the non-return position. Thus, when the main buckle 20 moves to the released position, the secondary buckle 30 is automatically moved to the non-return position under the action of the secondary drive reset member 52 and engaged with the main buckle 20, thereby facilitating the operation of the secondary buckle 30 engaging the main buckle 20. Of course, in other embodiments, the secondary drive reset member 52 may not be provided. When it is desired to release the retained engagement between the secondary buckle 30 and the main buckle 20, the user can reapply force to the secondary drive member 51 to move the secondary buckle 30 from the non-return position to the released position.

[0081] In some embodiments, the auxiliary drive component 51 is provided with an auxiliary drive inclined surface 51a, and the auxiliary buckle 30 is provided with a second inclined surface 30a corresponding to the auxiliary drive inclined surface 51a. The second inclined surface 30a slides against the auxiliary drive inclined surface 51a, so that when the auxiliary drive component 51 moves in the second direction, it can cause the auxiliary buckle 30 to move in a third direction, and the third direction intersects with both the first direction and the second direction. In other words, the auxiliary drive component 51 and the main drive component 41 both move in the second direction. In this way, the coordination of the auxiliary drive inclined surface 51a and the second inclined surface 30a achieves the reversing transmission of displacement, which can make the structure of the main buckle module and the auxiliary buckle module more compact and occupy a smaller volume. Of course, in other embodiments, the auxiliary drive component 51 can also move in a fourth direction, where the fourth direction intersects with the first direction, the second direction, and the third direction.

[0082] In order to make the structures of the main buckle module and the auxiliary buckle module more compact, in some embodiments, the auxiliary drive component 51 includes a sleeve portion 511 and an auxiliary drive portion 512 connected thereto, and the main drive component 41 includes a push rod portion 411 and a main drive portion 412 connected thereto, the push rod portion 411 being slidably disposed in the inner cavity of the sleeve portion 511 along the second direction, the main drive inclined surface 41a being disposed at an end of the main drive portion 412 away from the push rod portion 411, and the auxiliary drive inclined surface 51a being disposed at an end of the auxiliary drive portion 512 away from the sleeve portion 511. Of course, in other embodiments, the main drive component 41 and the auxiliary drive component 51 may be spaced apart along the third direction, that is, the main drive component 41 and the auxiliary drive component 51 are separated.

[0083] In some embodiments, two auxiliary drive units 512 are provided, and two corresponding auxiliary buckles 30 are provided. The two auxiliary buckles 30 are respectively provided on opposite sides of the main buckle 20 in the third direction. Thus, having an auxiliary buckle 30 on opposite sides of the main buckle 20 for retaining the main buckle 20 enhances the retaining effect of the auxiliary buckle 30 on the main buckle 20 and ensures that the force exerted by the auxiliary buckles 30 on the main buckle 20 is more balanced and stable. Of course, in other embodiments, only one auxiliary drive unit 512 and one auxiliary buckle 30 may be provided, or three or more auxiliary drive units 512 and two auxiliary buckles 30 may be provided.

[0084] In some embodiments, the secondary buckle 30 includes a connected second buckle portion 31 and a second inclined block 32. The second inclined surface 30a is provided on the second inclined block 32. The secondary drive portion 512 includes two auxiliary drive inclined surfaces 51a spaced apart along the first direction. The second inclined block 32 includes two corresponding auxiliary drive inclined surfaces 51a, which are located on opposite sides of the second buckle portion 31. The second buckle portion 31 is movably inserted into the gap formed between the two auxiliary drive inclined surfaces 51a. The auxiliary drive reset member 52 is located on the side of the second buckle portion 31 away from the main buckle 20. This can ensure more balanced force on the secondary buckle 30, smoother force transmission between the secondary buckle 30 and the auxiliary drive member 51, and a more compact structure. Specifically, the main buckle 20 optionally includes a retaining groove 20d corresponding to the second buckle portion 31. When the secondary buckle 30 is in the non-return position, the second buckle portion 31 is inserted into the retaining groove 20d. When the secondary buckle 30 is in the release position, the second buckle portion 31 is released from the retaining groove 20d. Of course, in other embodiments, the second buckle portion 31 may be provided with a slot, and the main buckle 20 may be provided with a corresponding protrusion, which is inserted into the slot when the secondary buckle 30 is in the non-return position. In still other embodiments, the second bevel 32 may not be provided, and the second buckle portion 31 may be provided with a groove on the side facing the secondary drive member 51, with the second bevel 30a provided at the bottom of the groove; or, only one second bevel 32 may be provided.

[0085] In some embodiments, the second buckle 31 is provided with a second guide post 33 corresponding to the auxiliary drive reset member 52, and the auxiliary drive reset member 52 is sleeved on the second guide post 33, and one end abuts on the second buckle 31, and the other end abuts on the inner wall surface of the base 10. Specifically, optionally, the mounting cavity 11 also includes a connected auxiliary buckle slide section 112 and a positioning groove section 113, the second inclined block 32 is slidably provided in the auxiliary buckle slide section 112, the auxiliary drive reset member 52 is adapted to be embedded in the positioning groove section 113, and its end away from the second buckle 31 abuts on the end wall of the positioning groove section 113. Further optionally, the auxiliary drive reset member 52 is configured as a compression spring. Of course, in other embodiments, the auxiliary drive reset member 52 can also be configured as a metal spring, an elastic rubber body or an elastic silicone body. In some other embodiments, the second guide post 33 can also be provided, and a guide hole can be provided on the end face of the second buckle 31, and one end of the auxiliary drive reset member 52 can be inserted into the guide hole.

[0086] For more details, please refer to Figure 5 and Figure 6 When the lens 90 locking mechanism is in the initial state, that is, the auxiliary buckle 30 is in the unlocked position, there is still some gap between the end face of the auxiliary buckle 30 away from the main buckle 20 and the end face of the auxiliary buckle slide section 112; and when the auxiliary buckle 30 is in the retracted limit position, the end face of the auxiliary buckle 30 away from the main buckle 20 abuts against the end face of the auxiliary buckle slide section 112. In this way, the auxiliary drive member 51 moves along the second direction and has an auxiliary drive initial position, an auxiliary drive second position and an auxiliary drive third position, which respectively correspond to the unlocked position, the non-return position and the retracted limit position of the auxiliary buckle 30. For further information, please refer to Figures 1 to 5 、 Figure 7 、 Figure 9 and Figure 11 , the lens 90 locking mechanism in the figure is in the initial state, at this time the main buckle 20 is in the locking position, the main drive member 41 is in the main drive starting position, the auxiliary buckle 30 is in the unlocking position, and the auxiliary drive member 51 is in the auxiliary drive starting position. Figures 12 to 15 , the lens 90 locking mechanism in the figure is in the unlocked state, at this time the main buckle 20 is in the unlocked position, the main drive member 41 is in the main drive second position, the auxiliary buckle 30 is in the non-return position, and the auxiliary drive member 51 is in the auxiliary drive second position. Figures 16 to 19 , the lens 90 locking mechanism in the figure is in the unlocked state, at this time the main buckle 20 is in the locked position, the main drive member 41 is in the main drive starting position, the auxiliary buckle 30 is in the retracted limit position, and the auxiliary drive member 51 is in the auxiliary drive third position. Figure 7 、 Figure 13 and Figure 17 It can be seen that when the auxiliary driving member 51 is pressed down from the auxiliary driving second position, it will first pass through the auxiliary driving starting position and then reach the auxiliary driving third position, while actuating the auxiliary buckle 30 to start retracting from the non-return position, and first pass through the non-return position and then reach the retraction limit position.

[0087] It is understood that even if the secondary buckle 30 is only retracted to the unlocked position, its second buckle portion 31 can still completely disengage the limiting groove 20d of the primary buckle 20, thereby allowing the primary buckle 20 to automatically return to the locked position under the action of the main drive reset member 42. By adding a withdrawal limit position, the risk of the second buckle portion 31 not being able to completely disengage the limiting groove 20d due to dimensional tolerances or assembly tolerances can be reduced, thereby improving the operational stability and reliability of the lens 90 locking mechanism. Of course, in other embodiments, the withdrawal limit position can be omitted. That is, when the secondary buckle 30 is in the unlocked position, the end surface of the secondary buckle 30 away from the main buckle 20 abuts the end surface of the secondary buckle slide segment 112.

[0088] Please refer to Figures 4 to 9 In some embodiments, the main buckle 20 includes a connected first buckle portion 21 and a first beveled block 22. The first beveled surface 20a is provided on the first beveled block 22. The main drive portion 412 is provided with two main drive beveled surfaces 41a spaced apart along the second direction. Two first beveled blocks 22 are provided, one on each side of the first buckle portion 21. The first buckle portion 21 is movably inserted into the gap formed between the two main drive beveled surfaces 41a. This ensures more balanced force on the main buckle 20, smoother force transmission between the main buckle 20 and the main drive component 41, and a more compact structure. It is worth noting that in the embodiment where the base 10 is provided with a mounting cavity 11 and a first through-hole 12, one end of the first buckle portion 21 is movably inserted into the first through-hole 12. Of course, in other embodiments, the first beveled block 22 may not be provided. The first buckle portion 21 may have a groove on the side facing the main drive component 41, with the first beveled surface 20a provided on the bottom surface of the groove. Alternatively, only one first beveled block 22 may be provided.

[0089] In some embodiments, the main drive component 41 also includes a mounting portion 413 integrally formed with the main drive portion 412, and the mounting portion 413 is detachably connected to the push rod portion 411. Specifically, optionally, the push rod portion 411 is provided with a mounting slider 415, and the mounting portion 413 is provided with a mounting slot 414 corresponding to the mounting slider 415, and the mounting slot 414 extends in a direction orthogonal to the second direction. Further optionally, the mounting cavity 11 also includes a main drive slot section 114 extending along the second direction, and the end of the main drive portion 412 away from the mounting portion 413 is slidably arranged in the main drive slot section 114. In this way, by separating the main drive portion 412 and the push rod portion 411, the production and manufacturing of the main drive component 41 is facilitated. Of course, in other embodiments, the main drive portion 412, the mounting portion 413 and the push rod portion 411 can be integrally formed, or the push rod portion 411 and the mounting portion 413 can be separated but fixed together. In some other embodiments, the push rod portion 411 may be detachably connected to the mounting portion 413 by screw locking.

[0090] Please refer to Figures 7 to 9 In some embodiments, the sleeve portion 511 includes a first barrel portion 513, a second barrel portion 514 connected between the first barrel portion 513 and the auxiliary drive portion 512, the second barrel portion 514 is arranged between the two auxiliary drive portions 512 and is provided with a mounting opening 51b on the side close to the first through hole 12. After the push rod portion 411 is slidably inserted into the inner cavity of the first barrel portion 513, the mounting portion 413 can pass through the mounting opening 51b along the first direction so that the mounting slider 415 slides into the mounting slot 414. In this way, the structure of the main buckle module and the auxiliary buckle module can be made more compact and occupy a smaller volume. It is worth mentioning that in the embodiment in which the base 10 is provided with the mounting cavity 11 and the second through hole 13, optionally, the first barrel portion 513 is inserted into the second through hole 13, and the push rod portion 411 is inserted into the inner cavity of the first barrel portion 513.

[0091] Please refer to Figures 1 to 3 The present invention further provides a pair of smart glasses comprising a frame 80, a lens 90, and the aforementioned locking mechanism for the lens 90. The specific structure of the locking mechanism for the lens 90 is similar to that of the aforementioned embodiments. Since the present smart glasses utilize all the technical solutions of all the aforementioned embodiments, they at least possess all the beneficial effects brought about by the technical solutions of the aforementioned embodiments, and therefore will not be described in detail here. Specifically, the base 10 of the locking mechanism for the lens 90 is disposed on the frame 80, and the main buckle 20 is in position-limiting connection with the lens 90.

[0092] In some embodiments, the frame 80 includes a frame shell 81, which is provided with a receiving cavity 81a, an operation through hole 81b and a lock tongue through hole 81c both connected to the receiving cavity 81a, and the lens 90 is provided with a lock tongue hole 91 corresponding to the lock tongue through hole 81c. The lens 90 locking mechanism is at least partially provided in the receiving cavity 81a, and one end of the main buckle 20 can pass through the lock tongue through hole 81c and extend into the lock hole to achieve locking and fixing of the lens 90; the main drive component 40 of the lens 90 locking mechanism is at least partially exposed in the operation through hole 81b for operation. In this way, the lens 90 locking mechanism can be well protected and the appearance of the smart glasses can be made neater and more beautiful. Of course, in other embodiments, the lens 90 locking mechanism can also be provided on the outer side of the frame shell 81.

[0093] Please refer to Figures 19 to 21In some embodiments, the frame 81 defines an insert hole 82 for inserting the lens 90. A latch hole 81c is provided on the wall of the insert hole 82. The insert hole 82 also has an insertion hole 81d on the wall opposite the latch hole 81c. The lens 90 has an inserting portion 92 corresponding to the insertion hole 81d, and the inserting portion 92 is inserted into the insertion hole 81d. This simplifies the structure of the smart glasses and reduces manufacturing costs. It is worth mentioning that in the embodiment where the main buckle 20 moves along the first direction and the main drive member 41 and the auxiliary drive member 51 both move along the second direction, optionally, the operation hole 81b is provided at the inner edge of the inlay hole 82, so that the main drive member 41 and the auxiliary drive member 51 can be located on the spacious and flat inner side of the frame shell 81. The operation space here is large and convenient for user operation, thereby improving the convenience of use, and the operation hole 81b will not be exposed on the outer side of the smart glasses, and the operation hole 81b is small in area and will not damage the overall shape of the appearance, thereby helping to improve the aesthetics of the product. Of course, in other embodiments, at least two lens 90 locking mechanisms can also be provided, and the two lens 90 locking mechanisms are respectively provided on opposite sides of the inlay hole 82, that is, the inlay hole 82 is provided with a lock tongue hole 81c on the hole walls on both sides.

[0094] Please refer to Figure 3 In some embodiments, a conduit portion 83 is protruding from the inner edge of the operating hole 81b, and the first barrel portion 513 is slidably inserted into the inner cavity of the conduit portion 83. In this way, the conduit portion 83 can effectively guide and position the first barrel portion 513, thereby improving the smoothness and stability of the lens 90 locking mechanism. Specifically, the height of the conduit portion 83 may exceed the travel range of the first barrel portion 513 to prevent the first barrel portion 513 from accidentally slipping out of the conduit portion 83, thereby causing the lens 90 locking mechanism to fail. Of course, in other embodiments, the conduit portion 83 may not be provided.

[0095] It should be noted that when the user performs unlocking and locking operations on the lens 90, the locking mechanism of the lens 90 switches between the locked state, the unlocked state and the released state. Correspondingly, the main buckle 20 switches between the locked position and the unlocked position, and the auxiliary buckle 30 switches between the released position, the non-return position and the retracted limit position. The specific process is as follows:

[0096] Please refer to Figure 3 In the default state, the lens 90 on the frame 80 is in a locked state, that is, the lens 90 locking mechanism is in the initial state, the main buckle 20 is in the locked position, the auxiliary buckle 30 is in the unlocked position, the main drive component 41 is in the main drive starting position, and the auxiliary drive component 51 is in the auxiliary drive starting position; at this time, the top surface of the drive component (that is, the top surface of the first barrel 513) exceeds the outer surface of the frame shell 81, and the top surface of the main drive component 41 (that is, the top surface of the push rod portion 411) is roughly flush with the outer surface of the frame shell 81.

[0097] Please refer to Figure 15 When the user performs the unlocking operation, the main drive part 41 moves downward by pressing the push rod part 411, and the main buckle 20 is prompted to move to the unlocking position, and then the auxiliary buckle 30 automatically moves to the non-return position to restrict the main buckle 20, and the movement of the auxiliary buckle 30 prompts the auxiliary drive part 51 to be lifted to the auxiliary drive second position; at this time, the top surface of the first barrel 513 exceeds the outer surface of the frame shell 81 by a greater height, which is convenient for the user to perform the locking operation.

[0098] Please refer to Figure 19 When the user replaces the lens 90 and performs the locking operation, the user presses down the raised first barrel portion 513 until it is roughly flush with the outer surface of the frame shell 81, prompting the auxiliary buckle 30 to move to the retraction limit position and release the restriction on the main buckle 20, so that the main buckle 20 can move to the locking position under the action of the main drive reset member 42, and realize the locking and fixation of the lens 90; and the movement of the main buckle 20 prompts the main drive member 41 to be lifted to the main drive starting position, that is, the top surface of the push rod portion 411 is roughly flush with the outer surface of the frame shell 81. When the user cancels the downward pressure on the first barrel portion 513, the auxiliary buckle 30 moves forward in the direction close to the main buckle 20 under the action of the auxiliary drive reset member 52, and returns to the check position. At the same time, the auxiliary drive is prompted by the auxiliary buckle 30 to return to the auxiliary drive starting position, that is, the lens 90 locking mechanism automatically returns to the position as shown. Figure 3 The starting state is shown.

[0099] The above descriptions are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present description and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
