[0051] The present invention provides a locking assembly 100 .

[0052] Please refer to Figures 1 to 7 In one embodiment of the present invention, the lock assembly 100 includes a fixed seat 10, a driving rod 20, a swinging member 30 and a first elastic member 40. The fixed seat 10 includes a seat body 11 and a cylinder 12 connected to the seat body 11, and the seat body 11 is used to be fixed on the first component; the driving rod 20 is inserted into the cylinder 12 and is spirally connected to the cylinder 12, and the driving rod 20 can move and rotate axially relative to the cylinder 12; the swinging member 30 is provided on the side of the seat body 11 away from the cylinder 12 and is sleeved on the outer periphery of the driving rod 20, and the swinging member 30 can rotate with the driving rod 20, and the driving rod 20 can slide axially relative to the swinging member 30, and the swinging member 30 has a locking position for locking the second component and an unlocking position for releasing the second component; the first elastic member 40 connects the seat body 11 and the swinging member 30, and the first elastic member 40 is used to provide an elastic force to keep the swinging member 30 in the locked position.

[0053] The locking assembly 100 can be used for quick disassembly and assembly between the first component and the second component. The following mainly takes the locking assembly 100 applied to glasses as an example. Figure 10 and Figure 11 As shown, the first component can be a frame 200, and the second component can be a lens 300. In actual application, the above-mentioned locking assembly 100 can be arranged at several suitable positions around the lens 300 according to the structural space of the glasses, or used in conjunction with a fixed buckle to lock the lens 300. Optionally, the side of the lens 300 is provided with a buckle groove that cooperates with the swinging member 30.

[0054] Specifically, the fixing seat 10 includes a seat body 11 and a barrel 12. Optionally, the seat body 11 and the barrel 12 are integrally formed to simplify the manufacturing process and ensure structural strength. Of course, the seat body 11 and the barrel 12 can also be split into two independent components and then connected and fixed. The seat body 11 is used to be fixed on a first component (such as a mirror frame 200), wherein the seat body 11 and the mirror frame 200 are assembled into one by means of screw connection, snap connection, welding, etc. Optionally, the seat body 11 is provided with a fixing hole 116 for a fastener 500 to pass through, and the seat body 11 can be fixed to the first component by the fastener 500. The barrel 12 extends upward from the top surface of the seat body 11, and a through hole is formed inside the barrel 12 that runs through from top to bottom. The drive rod 20 is inserted into the barrel 12, and the two ends of the drive rod 20 can extend out of the barrel 12 respectively. The drive rod 20 and the cylinder 12 can be spirally connected by designing a rail groove structure, so that the drive rod 20 can achieve a compound motion of sliding back and forth relative to the cylinder 12 in the axial direction and rotating around the axis. It can be understood that the structural size gap between the drive rod 20 and the cylinder 12 must meet the requirements of smooth and stable sliding and rotational motion. The swinging member 30 can be arranged on the side of the seat body 11 away from the cylinder 12 and sleeved on the periphery of the drive rod 20. When the seat body 11 is fixed to the first component, the axial direction of the swinging member 30 can be limited by the seat body 11 and the first component, so that the drive rod 20 can slide back and forth in the axial direction relative to the swinging member 30, and the swinging member 30 can rotate with the drive rod 20. The swinging member 30 is in the locked position (such as Figure 12 position shown) and unlocked position (as Figure 14 The first elastic member 40 is used to provide an elastic force to keep the swing member 30 in the locked position.

[0055] When the locking assembly 100 of the present invention is applied to glasses, the seat body 11 can be fixed to the frame 200, and the lens 300 can be locked or released by the swinging member 30, so as to realize the rapid disassembly and replacement of the lens 300 and the frame 200. Specifically, in the non-operating state, the swinging member 30 is maintained in the locked position of the lens 300 under the action of the first elastic member 40. When it is necessary to disassemble and replace the lens 300, it is only necessary to apply downward pressing force to the driving rod 20, and the driving rod 20 slides downward and rotates axially relative to the cylinder 12. The rotation of the driving rod 20 drives the swinging member 30 to overcome the elastic force of the first elastic member 40, so that the swinging member 300 rotates from the locked position to the unlocked position. In the unlocked position, the swinging member 30 releases the lens 300, and the user can remove the lens 300 from the frame 200 for replacement or cleaning. The disassembly process is simple and convenient. When the lens 300 needs to be installed, the driving rod 20 is first pressed to drive the swing member 30 to move to the unlocked position. After the lens 300 is installed, the pressing force on the driving rod 20 is removed. Under the elastic force of the first elastic member 40, the swing member 30 automatically returns to the locked position to lock the lens 300 on the frame 200. At the same time, the driving rod 20 can also rotate in the opposite direction and slide upward to the initial position, making the installation process simple and convenient. The technical solution of the present invention can achieve rapid disassembly and installation of the lens 300 and the frame 200, so that the user can quickly disassemble, replace or clean the lens 300 at any time, thereby improving the user experience.

[0056] In order to further improve the convenience of disassembly and installation of the lens 300, please refer to Figure 1 and Figure 2 In one embodiment, the lock assembly 100 further includes a limiting mechanism 50 and an unlocking member 60. The limiting mechanism 50 is provided on one side of the swinging member 30, and the unlocking member 60 cooperates with the limiting mechanism 50; the limiting mechanism 50 is used to lock the swinging member 30 when the swinging member 30 is in the unlocked position; the unlocking member 60 is used to drive the limiting mechanism 50 to release the swinging member 30 under the action of an external force.

[0057] In this embodiment, a limiting mechanism 50 is provided on one side of the swinging member 30. When the driving rod 20 is pressed to move the swinging member 30 to the unlocked position, the limiting mechanism 50 can lock the swinging member 30 to maintain the unlocked position. At this point, the user does not need to continue pressing the driving rod 20. The swinging member 30 can be locked in a limited state away from the lens 300, which does not interfere with the removal and installation of the lens 300. The user can free both hands and conveniently remove and install the lens 300 with both hands. When it is necessary to lock the lens 300, only a force is applied to the unlocking member 60, which drives the limiting mechanism 50 to release the swinging member 30. The swinging member 30 automatically returns to the locked position under the action of the first elastic member 40. This further improves the convenience of removing and installing the lens 300 and enhances the user experience. The limiting mechanism 50 and the swinging member 30 can be locked by, but not limited to, a buckle groove matching structure, a magnetic matching structure, or other locking structures, which are not specifically limited here.

[0058] Please refer to Figure 8 、 Figure 9 and Figure 11 In one embodiment, the limiting mechanism 50 can elastically and telescopically abut the circumferential side of the swinging member 30, and the limiting mechanism 50 has a first inclined surface 5141 extending obliquely from top to bottom toward the swinging member 30; the unlocking member 60 includes a sleeve 61 and an inclined wedge portion 63 provided on one side of the sleeve 61, the inclined wedge portion 63 having a second inclined surface 631 that cooperates with the first inclined surface 5141, and the sleeve 61 is sleeved on the outer periphery of the cylinder 12; when the sleeve 61 is subjected to axial pressing force, the inclined wedge portion 63 drives the limiting mechanism 50 to move toward the side away from the swinging member 30 to release the swinging member 30.

[0059] In this embodiment, the unlocking member 60 includes a sleeve 61 and a driving arm 62 disposed on one side of the sleeve 61. The sleeve 61 is sleeved around the periphery of the cylinder 12 and extends upward to the periphery of the driving rod 20. The driving arm 62 extends outward from the circumference of the sleeve 61 and bends downward. The lower end of the driving arm 62 is provided with a wedge portion 63. The limiting mechanism 50 can elastically and telescopically abut the circumference of the swinging member 30. The limiting mechanism 50 has a first inclined surface 5141 extending obliquely from top to bottom toward the swinging member 30. The wedge portion 63 has a second inclined surface 631 that mates with the first inclined surface 5141. The second inclined surface 631 slidably engages the first inclined surface 5141, thereby converting the axial movement of the sleeve 61 into horizontal telescopic movement of the limiting mechanism 50, thereby unlocking the swinging member 30. The structure is simple and the engagement is stable and reliable. Specifically, after the limiting mechanism 50 locks the swinging member 30, the user only needs to press the sleeve 61 downward, and the second inclined surface 631 of the wedge portion 63 slides downward along the first inclined surface 5141 and pushes the limiting mechanism 50 toward the side away from the swinging member 30, thereby releasing the swinging member 30. The swinging member 30 can then return to the locked position under the action of the first elastic member 40. When the pressing force on the sleeve 61 is removed, the limiting mechanism 50 returns to its original position under its own resilience and pushes the wedge portion 63 upward via the first inclined surface 5141, thereby pushing the sleeve 61 upward and returning to its original position, facilitating the next pressing operation.

[0060] When the user needs to remove or replace the lens 300, he only needs to press the drive rod 20 first to move the swinging member 30 to the unlocked position to release the lens 300; at this time, the limiting mechanism 50 locks the swinging member 30 in the unlocked position, and the user can free his hands and calmly remove and install the lens 300; when the lens 300 is installed, pressing the sleeve 61 again can enable the limiting mechanism 50 to release the swinging member 30, and the swinging member 30 automatically resets to the locked position under the action of the first elastic member 40 to lock the lens 300 to the frame 200. The entire disassembly and installation process only requires two pressing operations, which is simple and convenient to operate. In addition, the operating points required for the pressing operation are small, which makes the lock assembly 100 take up less space. For example, the diameter of the drive rod 20 can be designed to be smaller, and during the pressing operation, the drive rod 20 can be directly pressed by a pin.

[0061] Please refer to Figure 2 、 Figure 7 、 Figure 8 and Figure 14In one embodiment, the limiting mechanism 50 includes a limiting member 51 and a second elastic member 52. The limiting member 51 includes a main body 511 and a latch 512 provided on one side of the main body 511. The main body 511 is provided with a slot 514 for inserting the inclined wedge portion 63. One side of the slot 514 forms a first inclined surface 5141. One end of the second elastic member 52 elastically abuts against a side of the main body 511 away from the latch 512, and the other end elastically abuts against the seat body 11. A stop groove 31 is provided on the circumferential side of the swinging member 30. When the swinging member 30 is in the unlocked position, the latch 512 is inserted into the stop groove 31.

[0062] In this embodiment, a slot 514 is provided in the main body 511 of the limiting member 51 for inserting the wedge portion 63. The slot walls on both sides of the slot limit the wedge portion 63, preventing the wedge portion 63 from deflecting during sliding. This ensures a more stable and reliable sliding fit between the second inclined surface 631 and the first inclined surface 5141. When the swing member 30 is in the locked position, the latch 512 abuts against one side of the swing member 30. When the drive rod 20 is pressed, the swing member 30 rotates from the locked position toward the unlocked position. When the swing member 30 rotates to the unlocked position, the latch 512 engages the stop groove 31 to lock the swing member 30. The locking mechanism achieved by the latch 512 and the stop groove 31 is simple and stable. Furthermore, the second elastic member 52 applies an elastic force to the limiting member 51 toward the side of the swing member 30, preventing the latch 512 from dislodging from the stop groove 31, further ensuring locking stability. The second elastic member 52 includes but is not limited to a spring, a spring sheet, an elastic rubber column or other elastic structures.

[0063] Optionally, the limiting member 51 further includes a guide rod 513, which is disposed on a side of the main body 511 away from the latch 512, and the second elastic member 52 is sleeved around the guide rod 513. The provision of the guide rod 513 not only facilitates the installation of the second elastic member 52 but also guides the extension and contraction of the second elastic member 52.

[0064] like Figure 7 Heat Exchange Figure 8 As shown, in one embodiment, the stop groove 31 has a relative stop plane 311 and a guide slope 312, the guide slope 312 is located on the side of the stop groove 31 close to the unlocking position, and the guide slope 312 extends obliquely from the inside to the outside toward the side away from the stop plane 311, and the latch 512 has a stop mating surface 5121 that cooperates with the stop plane 311, and a guide mating surface 5122 that cooperates with the guide slope 312.

[0065] In this embodiment, the stop groove 31 is generally trapezoidal, and the latch 512 has a trapezoidal structure that matches the shape of the stop groove 31. Of course, the stop groove 31 can also be designed as a triangular groove or other special-shaped groove structure, with the latch 512's shape matching the shape of the stop groove 31. The stop flat surface 311 and the guide inclined surface 312 are arranged opposite each other, giving the stop groove 31 an expanded structure that expands from the inside outward, facilitating the smooth insertion of the latch 512 of the limiting member 51 into the stop groove 31. When the latch 512 is inserted into the stop groove 31, the stop flat surface 311 abuts the stop mating surface 5121, effectively locking the swinging member 30. The guide bevel 312 abuts against the guide mating surface 5122. When the unlocking member 60 is pressed, the limiting mechanism 50 moves away from the swinging member 30. The latch 512 can easily disengage from the stop groove 31 along the guide bevel 312, thereby releasing the swinging member 30.

[0066] Please refer to Figure 1 、 Figure 3 and Figure 5 In one embodiment, the outer circumferential surface of the drive rod 20 is provided with a plurality of spiral ribs 21 arranged at intervals along the circumference of the drive rod 20, and each spiral rib 21 is arranged to extend spirally along the axial direction of the drive rod 20, and the inner circumferential surface of the cylinder 12 is provided with a spiral groove 121 that corresponds to and slides with the spiral rib 21. In this way, when the drive rod 20 is inserted into the cylinder 12, the spiral rib 21 can be inserted into the corresponding spiral groove 121, thereby realizing the spiral connection between the drive rod 20 and the cylinder 12, so that when the drive rod 20 is subjected to an axial force, it can realize a composite movement of axial movement and rotation, with a simple structure and stable and reliable cooperation. Of course, in some embodiments, a spiral groove 121 can be provided on the outer circumferential surface of the drive rod 20, and a spiral rib 21 that is adapted to the spiral groove 121 can be provided on the inner circumferential surface of the cylinder 12.

[0067] Please refer to Figure 2 、 Figure 5 and Figure 7To transmit the torque of the drive rod 20 to the swing member 30, in one embodiment, the swing member 30 is provided with a through hole 32 for the drive rod 20 to pass through. A key slot 22 is provided on one of the outer circumference of the drive rod 20 and the inner circumference of the through hole 32, while a key pin 33 is provided on the other circumference to engage with the key slot 22. The key pin 33 is able to slide along the key slot 22 in the axial direction of the drive rod 20. For example, in this embodiment, the outer circumference of the bottom end of the drive rod 20 is provided with an axially extending key slot 22, while the inner circumference of the through hole 32 of the swing member 30 is provided with a key pin 33. It will be appreciated that in order for the drive rod 20 to slide axially relative to the swing member 30, the key slot 22 needs to have a certain amount of travel to allow the key pin 33 to slide. Of course, the positions of the key slot 22 and the key pin 33 can also be interchanged. Furthermore, in this embodiment, the key pin 33 is integral with the swing member 30, but in actual applications, it can also be designed as a separate structure based on the size and space.

[0068] like Figure 4 、 Figure 6 and Figure 7 As shown, in one embodiment, the first elastic member 40 is a torsion spring, which is sleeved around the periphery of the drive rod 20. The torsion spring has a fixed arm 41 and a movable arm 42. The base body 11 is provided with a first limiting groove 111 that cooperates with the fixed arm 41, and the swinging member 30 is provided with a second limiting groove 34 that cooperates with the movable arm 42. In this embodiment, the first elastic member 40 is a torsion spring, which has a compact structure, is easy to assemble, and occupies a small space, which facilitates the miniaturization of the lock assembly 100. The torsion spring is sleeved on the drive rod 20, and the fixed arm 41 of the torsion spring is limited by the first limiting groove 111, and the movable arm 42 of the torsion spring is limited by the second limiting groove 34. This ensures the assembly stability of the torsion spring, and thus the movement reliability of the entire lock assembly 100. Of course, in other embodiments, elastic members with other structures can also be used to provide the swinging member 30 with an elastic force toward the locked position.

[0069] Based on the above embodiments, Figure 4As shown, in one embodiment, a first accommodating chamber 112 for accommodating the limiting mechanism 50 and a second accommodating chamber 113 for accommodating the swinging member 30 are provided on a side of the seat body 11 facing away from the cylinder body 12. The first accommodating chamber 112 is connected to the second accommodating chamber 113. The second accommodating chamber 113 has an opening on a side facing away from the first accommodating chamber 112. The swinging member 30 has a locking end 35 extending from the opening. The locking end 35 is used to lock with the second component. In this embodiment, by providing the first accommodating chamber 112 and the second accommodating chamber 113 on the side of the seat body 11 facing away from the cylinder body 12, the installation of the limiting mechanism 50 and the swinging member 30 can be facilitated, making the overall structure more compact. In addition, the side walls of the first accommodating chamber 112 and the second accommodating chamber 113 can also play a certain guiding role in the movement of the limiting mechanism 50 and the swinging member 30, respectively, to ensure more precise movement of the entire lock assembly 100. The locking end 35 of the swing member 30 extends from the opening. When the swing member 30 is in the locked position, the locking end 35 is locked with the second component (such as the lens 300); when the swing member 30 is in the unlocked position, the locking end 35 is away from the lens 300 to release the lens 300.

[0070] Further, if Figure 4 As shown, a first limiting surface 114 and a second limiting surface 115 are respectively provided on opposite sides of the corresponding opening of the seat body 11. When the swing member 30 is in the locked position, the swing member 30 is in a limiting abutment with the first limiting surface 114. When the swing member 30 is in the unlocked position, the swing member 30 is in a limiting abutment with the second limiting surface 115. The first limiting surface 114 and the second limiting surface 115 can accurately limit the rotational travel of the swing member 30, thereby allowing the swing member 30 to accurately switch between the locked position and the unlocked position, thereby ensuring that the lock assembly 100 can accurately lock and release the lens 300.

[0071] like Figure 10 and Figure 11 As shown, the present invention also proposes a pair of glasses, which include a frame 200, a lens 300 and a locking assembly 100. The lens 300 is detachably mounted on the frame 200; the locking assembly 100 is fixed to the frame 200, and the locking assembly 100 is used to lock or release the lens 300. The specific structure of the locking assembly 100 refers to the above embodiment. Since the present glasses adopt all the technical solutions of all the above embodiments, they at least have all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the glasses include but are not limited to AR glasses, VR glasses or other types of glasses, which are not specifically limited here.

[0072] In one embodiment, the locking assembly 100 includes a fixed seat 10, a driving rod 20, a swinging member 30, and a first elastic member 40. The fixed seat 10 includes a seat body 11 and a barrel 12 connected to the seat body 11, and the seat body 11 is used to be fixed to the lens frame 200; the driving rod 20 is inserted into the barrel 12 and is spirally connected to the barrel 12, and the driving rod 20 can move and rotate axially relative to the barrel 12; the swinging member 30 is arranged on the side of the seat body 11 away from the barrel 12 and is sleeved on the outer periphery of the driving rod 20, and the swinging member 30 can rotate with the driving rod 20 and slide axially relative to the swinging member 30. The swinging member 30 has a locking position for locking the lens 300 and an unlocking position for releasing the lens 300; the first elastic member 40 connects the seat body 11 and the swinging member 30, and the first elastic member 40 is used to provide an elastic force to keep the swinging member 30 in the locked position.

[0073] In this embodiment, in the non-operating state, the swing member 30 is maintained in the locked position locking the lens 300 under the action of the first elastic member 40. When it is necessary to remove and replace the lens 300, it is only necessary to apply downward pressure to the drive rod 20. The drive rod 20 slides axially downward relative to the barrel 12 and rotates. The rotation of the drive rod 20 drives the swing member 30 to overcome the elastic force of the first elastic member 40, so that the swing member 30 rotates from the locked position to the unlocked position. In the unlocked position, the swing member 30 releases the lens 300, and the user can remove the lens 300 from the frame 200 for replacement or cleaning. The disassembly process is simple and convenient. When the lens 300 needs to be installed, the driving rod 20 is first pressed to drive the swing member 30 to move to the unlocked position. After the lens 300 is installed, the pressing force on the driving rod 20 is removed. Under the elastic force of the first elastic member 40, the swing member 30 automatically returns to the locked position to lock the lens 300 on the frame 200. At the same time, the driving rod 20 can also rotate in the opposite direction and slide upward to the initial position, making the installation process simple and convenient. The technical solution of the present invention can achieve rapid disassembly and installation of the lens 300 and the frame 200, so that the user can quickly disassemble, replace or clean the lens 300 at any time, thereby improving the user experience.

[0074] In one embodiment, the lock assembly 100 further includes a limiting mechanism 50 and an unlocking member 60. The limiting mechanism 50 is elastically and telescopically abutted against the circumference of the swinging member 30. The limiting mechanism 50 has a first inclined surface 5141 extending obliquely from top to bottom toward the swinging member 30. The unlocking member 60 includes a sleeve 61 and an inclined wedge portion 63 provided on one side of the sleeve 61. The inclined wedge portion 63 has a second inclined surface 631 that cooperates with the first inclined surface 5141. The sleeve 61 is sleeved around the outer periphery of the barrel 12. When the sleeve 61 is subjected to axial pressure, the inclined wedge portion 63 drives the limiting mechanism 50 to move toward a side away from the swinging member 30. The eyeglass frame 200 includes a frame body 210 and an inner cover 220. The frame body 210 and the inner cover 220 enclose a mounting cavity for accommodating the lock assembly 100. The inner cover 220 is provided with a through hole for the drive rod 20 and the sleeve 61 to pass through.

[0075] In this embodiment, the lock assembly 100 is installed in the installation cavity formed by the frame body 210 and the frame inner cover 220, which does not damage the overall appearance and user experience of the glasses. In addition, the frame inner cover 220 is provided with a through hole for the drive rod 20 and the sleeve 61 of the unlocking member 60 to pass through, which can facilitate the user to press the operation to achieve the locking and release of the lens 300 and the frame 200. Optionally, as Figure 11 As shown, the frame inner cover 220 is provided with a guide tube 221 extending from a perforated periphery toward the frame body 210. The guide tube 221 is sleeved around the outer periphery of the sleeve 61. The provision of the guide tube 221 guides the axial movement of the drive rod 20 and the sleeve 61, ensuring smoother movement and preventing derailment. To prevent interference with the movement of the drive rod 20, a clearance hole 201 is also provided on the frame body 210 at the lower end of the drive rod 20.

[0076] The following combination Figures 11 to 18 , a detailed introduction is given to the specific movement process of the locking assembly 100 of one embodiment when applied to glasses.

[0077] like Figure 11 As shown in FIG, it is a schematic diagram of the working state of the locking assembly 100 locking the lens 300 when the lens 300 is in normal use in the non-operating state. From the appearance of the glasses, the top surfaces of the driving rod 20 and the sleeve 61 are both located on the surface of the inner cover 220 of the frame, showing a non-operating release state. Figure 12 As shown in the figure, from the internal structure, the locking assembly 100 is now in the locked position, locking the lens 300, by supporting the swinging member 30 via the first elastic member 40. The barrel 12 and the swinging member 30 jointly hold the drive rod 20 in its current position. Under the pressure of the second elastic member 52, the stopper 51 presses against the circumference of the swinging member 30. The first inclined surface 5141 of the stopper 51 cooperates with the second inclined surface 631 of the wedge portion 63 to hold the sleeve 61 in its current position.

[0078] When the lens 300 needs to be disassembled and replaced, the driving rod 20 is pressed first to release the locking assembly 100 to release the lens 300. For ease of operation, the driving rod 20 can be pressed by inserting a pin. Figure 13 As shown in FIG, the operating state of the locking assembly 100 releasing the lens 300 before the lens 300 is changed by pressing the driving rod 20 downward. From the appearance of the glasses, the top surface of the driving rod 20 is pressed inward, and the sleeve 61 of the unlocking member 60 is lifted above the surface of the inner cover 220 of the frame. Figure 14 As shown, from the internal structure, the drive rod 20 of the lock assembly 100 is pressed downward, rotating downward relative to the barrel 12. The drive rod 20 drives the swinging member 30 to overcome the elastic force of the first elastic member 40 and rotate to the unlocked position, releasing the lens 300. At this time, the stop groove 31 on the swinging member 30 rotates to the position corresponding to the latch 512 of the stop member 51. Driven by the second elastic member 52, the latch 512 advances and inserts into the stop groove 31. The stop surface 311 of the stop groove 31 locks the swinging member 30 to maintain the unlocked position. The lens 300 is released, allowing it to be removed and replaced. When the latch 512 of the stop member 51 advances to the stop groove 31, it simultaneously lifts the sleeve 61 of the unlocking member 60 upward by a corresponding distance, causing the top surface of the sleeve 61 to be higher than the surface of the frame inner cover 220, facilitating the subsequent pressing operation of the sleeve 61.

[0079] After replacing the lens 300, press down the sleeve 61 of the unlocking member 60 so that the locking assembly 100 locks the lens 300. Figure 15 As shown in FIG, the unlocking member 60 is pressed down, and after the lens 300 is replaced, the locking assembly 100 has locked the lens 300. From the appearance of the glasses, the top surface of the sleeve 61 is pressed down to the surface of the inner cover 220 of the frame, and the driving rod 20 is lifted to the surface of the inner cover 220 of the frame. Figure 16 As shown, from the internal structure, the sleeve 61 presses down to drive the limit member 51 to move backward, disengaging from the stop groove 31 of the swing member 30, and the limit member 51 and the second elastic member 52 are pressed to the rear stroke limit position. The swing member 30 is released by the limit member 51, and the swing member 30 is driven by the rebound of the first elastic member 40 to rotate to the locking position of the locking lens 300, pressing against the side buckle groove of the lens 300 to limit and fix the lens 300.

[0080] When the lens 300 is locked, the unlocking member 60 is released to remove the pressing force on the sleeve 61. Figure 17 As shown in the figure, it is a schematic diagram of the working state of the locking assembly 100 locking the lens 300 after the unlocking member 60 is released. From the appearance of the glasses, the top surface of the driving rod 20 and the sleeve 61 are both located on the surface of the inner cover 220 of the frame, showing a non-operation release state. Figure 18 As shown, from the internal structure, the limit member 51 moves forward slightly from the rear limit position under the leading drive of the second elastic member 52, until the front end of the limit member 51 presses against the peripheral side of the swing member 30 (the position of the non-stop groove 31), and the sleeve 61 synchronously resets slightly and rises to the non-operation release state. The position states of the drive rod 20, the swing member 30, the first elastic member 40, and the limit member 51 all return to the non-operation release state, completing the operation cycle.

[0081] By installing the above-mentioned locking assembly 100 on the frame 200 of the glasses, when the lens 300 needs to be replaced or removed, the pin is used to press the driving rod 20 to drive the swinging member 30 to rotate to the unlocking position to disengage the lens. The synchronous limit member 51 automatically locks the swinging member 30, and the lens can be removed. At this time, the swinging member 30 is locked in the limited state of being disengaged from the lens, which will not interfere with the process of removing and installing the lens. The hands are freed to disassemble and install the lens more easily and conveniently. After replacing the new lens, the sleeve 61 of the unlocking member 60 is pressed again to drive the limit member 51 to release the swinging member 30. The swinging member 30 rotates to the locking position under the action of the first elastic member 40 to lock the lens, and the replacement is completed. The entire operation process is simple and convenient, and only two presses are required. The operation point is small and does not damage the overall shape and user experience of the appearance. The entire motion mechanism occupies a small space and the function is stable and reliable.
