[0044] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0045] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0046] According to one embodiment of the present invention, a clamping mechanism is provided. Figure 1 , Figure 4-Figure 6As shown, the clamping mechanism 100 comprises:

[0047] A fixed portion 01 and a movable portion 02 that are detachably fixedly connected, wherein the fixed portion 01 is fixedly arranged relative to the movable portion 02, and the movable portion 02 is configured to be movable to a first position or a second position relative to the fixed portion 01;

[0048] A driving part 05, which is disposed on the movable part 02 and is used to drive the movable part 02 to move from the second position to the first position;

[0049] For example, the fixed part 01 and the movable part 02 can be fixedly connected by a snap-fitting manner. Under the driving action of the driving part, the movable part 02 and the fixed part 01 can be separated, so that the movable part 02 can move to the first position or the second position relative to the fixed part 01.

[0050] Torsion spring 03, along the axial direction of the torsion spring 03, the movable part 02 is connected to the upper end 031 of the torsion spring 03, and the lower end 032 of the torsion spring 03 is fixedly arranged relative to the movable part 02;

[0051] For example, along the axial direction of the torsion spring 03, the fixed part 01 is arranged on the movable part 02, and the movable part 02 is arranged on the torsion spring 03. When the movable part 02 moves to the first position, the movable part 02 moves away from the fixed part 01. When the movable part 02 moves to the second position, the movable part 02 moves close to the fixed part 01.

[0052] When the movable part 02 is in the first position, the movable part 02 and the fixed part 01 are separated, and the clamping mechanism is configured to adjust the angle of the two parts;

[0053] For example, the head-mounted device is set as glasses. When the clamping mechanism is applied to the glasses, when the movable part 02 is in the second position relative to the fixed part 01, the fixed part 01 and the movable part 02 are fixed together. At this time, the movable part 02 transmits torque to the fixed part 01, and the temples are not convenient to rotate;

[0054] When the movable part 02 is in the second position relative to the fixed part 01, when a user with a big head feels squeezed when wearing the glasses or the temples of the glasses cannot clamp the head of a user with a small head, it is necessary to make the movable part 02 in the first position relative to the fixed part 01, the fixed part 01 and the movable part 02 are in a separated state, the temples no longer have torque, and the user can adjust the angle A between the temples and the frame; for example, the angle between the temples and the frame gradually decreases, so that the glasses are suitable for users with big heads; the angle between the temples and the frame gradually increases, so that the glasses are suitable for users with small heads.

[0055] When the movable part 02 is in the second position, the movable part 02 and the fixed part 01 are in contact and fit, and the two are fixed together. The torsion spring 03 can generate a torque force along its circumferential direction, and the torque force is transmitted to the movable part 02, and the movable part 02 transmits the torque force to the fixed part 01.

[0056] When the movable part 02 is in the second position relative to the fixed part 01, the movable part 02 transmits torque to the fixed part 01; under the driving action of the driving part 05, the movable part 02 can be switched from the second position to the first position to adjust the angle between the two parts; when the driving part 05 no longer drives the movable part 02, the movable part 02 returns to the first position from the second position under the action of the torsion spring 03.

[0057] In a specific embodiment, referring to Figure 1-Figure 4 As shown, when the clamping mechanism is applied to a head-mounted device, the head-mounted device is configured as glasses, and the clamping mechanism is applied to the glasses, the movable part 02 is in the second position relative to the fixed part 01, and the fixed part 01 and the movable part 02 are fixed together. At this time, the movable part 02 can transmit the torque force generated by the torsion spring 03 to the movable part 02, and the movable part 02 transmits the torque force to the fixed part 01, and then the fixed part 01 can transmit the torque force to the temples. The head-mounted device 200 is in a wearing state, and the temples can clamp the user's head; when the clamping force provided by the temples is too large or too small and is not suitable for users to wear, at this time, under the driving action of the driving part 05, the movable part 02 can be switched from the second position to the first position to adjust the angle between the temples and the frame, so that the glasses are suitable for different users.

[0058] In this example, the clamping mechanism is applied to a head-mounted device, which can provide a clamping force for the head-mounted device to be clamped on the user's head, thereby preventing the head-mounted device from falling off the user's head. In addition, the head-mounted device is suitable for different users, thereby increasing the wide range of use of the head-mounted device.

[0059] Optionally, refer to Figure 4 As shown, a first surface 012 of the fixed part 01 in contact with the movable part 02 is provided with a first connecting part, and a second surface 021 of the movable part 02 in contact with the fixed part 01 is provided with a second connecting part. The first connecting part and the second connecting part are detachably fixedly connected.

[0060] Specifically, the fixed part 01 and the movable part 02 are detachably fixedly connected by a first connecting part and a second connecting part, the first connecting part may be provided with a card slot, and the second connecting part may be provided as a card block that cooperates with the card slot; or the first connecting part and the second connecting part may both be provided with a plurality of teeth that cooperate with each other, etc. The present invention does not specifically limit the structure of the first connecting part and the second connecting part, as long as the fixed part and the movable part can be detachably fixedly connected.

[0061] In this example, the connection method between the fixed part and the movable part is simple, which facilitates maintenance of the clamping mechanism.

[0062] Optionally, refer to Figure 4-Figure 5 As shown, the clamping mechanism 100 further includes a connecting shaft 04 , the torsion spring 03 and the movable portion 02 are sleeved on the connecting shaft 04 , and the lower end 032 of the torsion spring 03 is fixed to the connecting shaft 04 .

[0063] Specifically, along the axial direction of the connecting shaft 04 , the fixed portion 01 is located above the movable portion 02 , the movable portion 02 is sleeved on the connecting shaft 04 , and the connecting shaft 04 is used to carry the connecting torsion spring 03 ;.

[0064] For example, the clamping mechanism 100 is applied to a head-mounted device. When the head-mounted device is equipped with glasses, the connecting shaft 04 is fixed to the frame, and the lower end 032 of the torsion spring 03 is fixedly connected to the connecting shaft 04. When the driving part 05 no longer drives the movable part 02, the movable part 02 returns to the first position from the second position under the action of the torsion spring 03. Specifically, the movable part 02 returns to the first position from the second position along the axial direction of the connecting shaft 04.

[0065] In addition, the movable part 02 is sleeved on the connecting shaft 04. In this example, the connecting shaft 04 has a guiding function. When the movable part 02 switches from the first position to the second position, the force of the torsion spring applied to the movable part 02 along the axial direction of the connecting shaft 04 can fix the movable part 02 and the fixed part 01 together, thereby avoiding errors and the like when the movable part 02 and the fixed part 01 are matched, which would affect the use effect of the clamping mechanism.

[0066] Optionally, refer to Figure 4-Figure 6 As shown, the driving part 05 passes through the fixed part 01 and abuts against the movable part 02. The driving part 05 drives the movable part 02 to move the movable part 02 to the first position.

[0067] Specifically, the driving part 05 and the movable part 02 are in contact with each other. When the user presses the driving part 05 , the movable part 02 can be separated from the fixed part 01 , and the movable part 02 moves away from the fixed part 01 .

[0068] For example, the driving unit 05 can be configured as a button or the like.

[0069] For example, refer to Figure 6 As shown, along the axial direction of the connecting shaft 04, the movable part 02 is sleeved on the connecting shaft 04, and one end of the connecting shaft 04 is plugged into the driving part 05; the driving part presses the movable part 02, and the movable part 02 can move downward along the axial direction of the connecting shaft 04, thereby causing the movable part 02 to press the torsion spring 03. This example improves the connection reliability of the clamping mechanism.

[0070] Alternatively, the driving part 05 is disposed on the outer wall of the movable part 02 , for example, the driving part 05 is disposed on a convex block on the outer wall of the movable part 02 , and a user presses the convex block to separate the movable part 02 from the fixed part 01 .

[0071] Optionally, refer to Figure 4-Figure 6 As shown, the clamping mechanism 100 also includes an elastic member 06, one end of which is connected to the fixed portion 01, and the other end of which is connected to the top of the driving portion 05; when the driving portion 05 drives the movable portion 02, the elastic member 06 is in a compressed state.

[0072] Specifically, the elastic member 06 is arranged between the fixing member 01 and the driving member 05; when the user presses the driving member, the elastic member 06 is in a compressed state under the action of the driving member; when the user stops applying force to the driving member, the driving member is ejected under the action of the elastic member 06, so that the user can apply force to the driving member next time. Figure 6 As shown, a through hole 013 is provided in the fixed part 01, a blind hole 022 is provided in the movable part 02, and the through hole 013 and the blind hole 022 are connected; the lower end of the driving part 05 passes through the through hole 013 and abuts against the blind hole 022, and the upper end thereof protrudes from the fixed part 01.

[0073] Specifically, when the movable part is in the second position, the upper end of the driving part 05 protrudes from the fixing part 01 under the action of the elastic member, so that the user can press the driving part 05. In a specific embodiment, the present invention provides a head-mounted device. For example, the head-mounted device can be glasses.

[0074] Reference Figure 2-Figure 6 As shown, the head mounted device 200 comprises:

[0075] Temple 10, frame 11 and the clamping mechanism 100;

[0076] The temple 10 and the frame 11 are pivotally connected via the clamping mechanism 100; for example, when the head-mounted device is not worn, the temple 10 is folded relative to the frame 11 via the clamping mechanism;

[0077] The fixing part 01 is fixedly arranged on the temple 10, the lower end of the torsion spring 03 is fixed on the connecting shaft 04, and one end of the connecting shaft 04 is fixed on the frame 11;

[0078] When the movable portion 02 is in the first position, the angle between the temple 10 and the frame 11 is adjusted from the first angle to the second angle;

[0079] Reference Figure 3 As shown, the movable portion 02 is in the first position, and the angle A between the temple 10 and the frame 11 is adjustable. The user adjusts the temple 10 to be retracted in the direction indicated by arrow a, and the angle A between the temple 10 and the frame 11 becomes larger; the user adjusts the temple 10 to be expanded outwards as indicated by arrow b, and the angle A between the temple 10 and the frame 11 becomes smaller;

[0080] For example, in this example, the first angle is defined to be greater than the second angle. When the head-mounted device 200 is in a wearing state and the user has a large head, the temples 10 are tight at the first angle, and the head-mounted device is not suitable for users with large heads. At this time, the driving unit 05 drives the movable unit 02 to switch from the second position to the first position, and adjusts the angle between the temples 10 and the frame 11 from the first angle to the second angle; when the angle between the temples 10 and the frame 11 is adjusted from the first angle to the second angle, the two temples 07 need to be expanded outward so that users with large heads can wear the head-mounted device 200; similarly, when the head-mounted device 200 is not worn by users with small heads, the angle between the temples 10 and the frame 11 needs to be gradually increased; for example, the two temples 10 are retracted inward, and the angle between the temples 10 and the frame 11 gradually increases, so that users with small heads can wear the head-mounted device 200.

[0081] When the movable portion 02 is in the second position, the fixed portion 01 can transmit the torque force to the temple 10, the head-mounted device 200 is in a wearing state, and the temple 10 is configured to provide a clamping force for clamping the user's head.

[0082] When the movable portion 02 is in the first position, the movable portion 02 and the fixed portion 01 are separated from each other. At this time, the user can adjust the angle between the temple 10 and the frame 11, so that the head-mounted device can be suitable for different users.

[0083] When the movable part 02 is in the second position, the fixed part 01 can transmit the torque force to the temple 10; specifically, the head-mounted device 200 is in a wearing state, and the torque force enables the temple 10 to provide a clamping force to clamp the user's head.

[0084] In this example, the temple 10 and the frame are pivotally connected by a clamping mechanism 100. When the movable part 02 is in the first position, the angle between the temple 10 and the frame 11 is adjustable, so that when the movable part 02 is in the second position, the head-mounted device 200 is suitable for users with different head sizes; when the movable part 02 is in the second position, the clamping mechanism 100 can adjust the clamping force of the temple 10 on the user's head; on the other hand, the temple 10 can be folded relative to the frame around the clamping mechanism 100, so that the user can store the head-mounted device conveniently.

[0085] Optionally, the temple 10 is provided with a sleeve 101, and the frame 11 is formed with a first ring 111 and a second ring 112 that cooperate with the sleeve 101, and the first ring 111 and the second ring 112 are respectively arranged at two ends of the sleeve 101; the clamping mechanism is arranged in the sleeve 101 through the ring to connect the temple 10 and the frame 11.

[0086] Specifically, when the clamping mechanism is arranged in the sleeve 101, the connecting shaft 04 is arranged in the sleeve 101 through the second ring 112, wherein the end of the connecting shaft 04 away from the driving part 05 is fixed in the second ring 112; the driving part 05 is arranged in the sleeve 101 through the first ring 111, and the driving part 05 is movably arranged in the sleeve.

[0087] Optionally, the fixing portion 01 is provided with a protrusion 011 on its outer surface, and the sleeve 101 is provided with a groove matching the protrusion 011;

[0088] The head mounted device 200 further includes a limit block 07 , one end of which is fixed to the temple 10 , and the other end of which is located below the protrusion 011 for supporting the fixing portion 01 .

[0089] In this example, the fixing part 01 is provided with a protrusion 011 along its outer surface, and the protrusion 011 matches with the groove so that the protrusion 011 is stuck in the groove, thereby limiting the rotation of the fixing part 01 along the circumferential direction of the sleeve 101; one end of the limiting part 07 is located below the protrusion 011 and is used to support the fixing part 01, and the limiting part 07 and the elastic member 06 can limit the movement of the fixing part 01 along the axial direction of the sleeve 101. Optionally, the limiting part 07 is fixed to the head mounted device by a fastener 071.

[0090] Optionally, the head mounted device further comprises a flexible board 12 and a main board 13, and the flexible board 12 is electrically connected to the main board 13;

[0091] The main board 13 is disposed in the temple 10 , and an electronic device is disposed on the main board 13 . One end of the flexible board 12 is connected to the electronic device, and the other end of the flexible board 12 is disposed in the temple 10 .

[0092] Specifically, the flexible board 12 can deform following the movement of the temple 10 to avoid the flexible board 12 from breaking or the like; the main board 13 is provided with a variety of electronic devices, and the various electronic devices are electrically connected to the main board and the flexible board. In this example, the main board 13 can be provided on the temple to avoid the main board being provided outside the temple to affect the aesthetics of the head-mounted device. Optionally, the electronic device can be a camera, a display component, etc.
