[0035] See also Figure 1 , Figure 2 and Figure 3 The present application provides a fastener 100, which is configured to be detachably connected to a mating member 200, and the fastener 100 includes:

[0036] The connecting body 10 has a first end surface 11, the first end surface 11 is provided with a protrusion 12, and a side surface of the protrusion 12 is provided with a groove 121;

[0037] The hook member 20 comprises a hook end 21, a free end 22 opposite to the hook end 21, and a rotating arm 23 disposed between the hook end 21 and the free end 22, wherein the rotating arm 23 is rotatably connected to the inner wall of the groove 121;

[0038] A driving member 30 connected to the hook member 20 to drive the hook end 21 to extend out of the groove 121;

[0039] An unlocking member 40 is movably connected to the protrusion 12 and abuts against the free end 22 to provide a force acting in the opposite direction to the driving member 30;

[0040] When the unlocking member 40 does not drive the free end 22, the hook end 21 extends out of the groove 121 under the driving force of the driving member 30 to engage with the matching member;

[0041] When the unlocking member 40 drives the free end 22 , the free end 22 rotates relative to the rotation shaft 122 toward the opening of the groove 121 under the driving force of the unlocking member 40 , and drives the hook end 21 to retract into the groove 121 .

[0042] It is understandable that the buckle 100 can be applied to a wearable device so that two parts of the wearable device can be detachably connected. For example, the wearable device is a watch, and the buckle 100 is a dial. The wearable device can also be a smart bracelet, and the buckle 100 is the main body of the bracelet. In this embodiment, the buckle 100 is applied to a smart watch as an example.

[0043] The hook member 20 is rotatably arranged on the connecting body 10, and under the drive of the driving member 30, the hook end 21 can extend out of the groove 121, so that the hook end 21 can be engaged with the matching member, and the fastener 100 can be quickly and firmly connected with the matching member. When the unlocking member 40 contacts the free end 22, the hook end 21 can be retracted into the groove 121, so that the fastener 100 can be quickly separated from the matching member, thereby facilitating the fastener 100 to be quickly and detachably connected to the connection, saving time and effort and improving the disassembly and assembly efficiency.

[0044] In one embodiment, see Figure 3 , Figure 4 and Figure 5 , the buckle 100 is the watch body, that is, the buckle 100 is a dial. The connecting body 10 is provided with a frame 13, and the first end face 11 is arranged at the end of the frame 13. The connecting body 10 has two opposite ends, and the two ends are respectively used to connect with two matching pieces 200. The matching piece 200 is a watch strap. The buckle 100 is detachably connected with the matching piece 200, so that the buckle 100 can be disassembled and maintained.

[0045] Specifically, the frame 13 has two opposite long sides 131 and two opposite short sides 132. The short side 132 is connected between the two long sides 131. The end is arranged at the short side 132. The protrusion 12 extends from the first end surface 11 so that the protrusion 12 can be plugged into the watch band. The protrusion 12 has two opposite side surfaces in the thickness direction. The groove 121 is provided on one of the side surfaces of the protrusion 12 in the thickness direction so that the groove 121 has a larger opening, thereby facilitating the hook end 21 to extend out of or retract from the opening of the groove 121. The thickness direction of the protrusion 12 can be parallel to the thickness direction of the frame 13 or be arranged at a certain angle. In this embodiment, the thickness direction of the protrusion 12 is at an angle to the thickness direction of the frame 13, that is, the extension direction of the protrusion 12 is inclined relative to the two short sides 132.

[0046] Optionally, the groove 121 is formed on a side surface of the protrusion 12 adjacent to the top of the frame 13. The top of the frame 13 is used for fixed connection with the display screen assembly.

[0047] The rotating shaft 122 is fixed in the groove 121. Both ends of the rotating shaft 122 are connected to two inner walls of the groove 121 that are opposite to each other in the extending direction of the protrusion 12. The rotating shaft 122 is at a certain distance from the opening of the groove 121, so that the hook member 20 can be completely retracted into the groove 121, ensuring that the protrusion 12 is smoothly separated from the strap. The rotating shaft 122 is at a certain distance from the bottom of the groove 121, ensuring that the hook member 20 can smoothly rotate around the rotating shaft 122.

[0048] In this embodiment, the rotating arm 23 is provided with a rotating shaft hole 231, and the rotating shaft hole 231 cooperates with the rotating shaft 122, so that the hook member 20 can rotate around the rotating shaft 122. The rotating shaft hole 231 is close to the free end 22, so that the rotation radius of the hook end 21 is increased, so that the hook end 21 is convenient to extend out of the groove 121. The hook end 21 and the free end 22 are respectively located on both sides of the rotating shaft 122, so that when the hook end 21 extends out of the groove 121, the free end 22 is far away from the opening of the groove 121, so that the free end 22 can receive the push-up drive of the unlocking member 40, and when the hook end 21 is retracted into the groove 121, the free end 22 is close to the opening of the groove 121 under the push-up drive of the unlocking member 40.

[0049] When the hook end 21 extends out of the groove 121, the hook end 21 forms a boss structure on the side of the protrusion 12. The hook end 21 can hook a part of the matching piece 200, thereby limiting the movement of the matching piece 200 relative to the protrusion 12 to ensure that the buckle 100 is firmly connected to the strap.

[0050] When the hook end 21 is retracted into the groove 121 , the side surface of the protrusion 12 is flattened, so that the fitting member 200 can be easily separated and moved relative to the protrusion 12 , thereby facilitating the disassembly of the fitting member 200 and the connecting body 10 .

[0051] In this embodiment, the driving member 30 is disposed in the groove 121 and always applies a driving force to the hook member 20, so that when the unlocking member 40 is not driven on the hook member 20, the hook end 21 extends out of the groove 121 under the driving force of the driving member 30. When the unlocking member 40 is driven on the hook member 20, the driving force of the unlocking member 40 on the free end 22 is greater than the driving force of the driving member 30 on the hook member 20, so that the hook end 21 can be retracted into the groove 121.

[0052] In this embodiment, a portion of the unlocking member 40 is disposed in the groove 121, so that the unlocking member 40 can apply a driving force to the free end 22. Another portion of the unlocking member 40 is exposed to the outer surface of the protrusion 12, so that the unlocking member 40 receives a user's driving force, so that when the user needs to separate the buckle 100 from the mating member 200, a driving force is applied to the unlocking member 40, so that the unlocking member 40 is driven to the free end 22, so that the hook end 21 is retracted into the groove 121, thereby realizing the separation of the buckle 100 from the watchband.

[0053] It is understandable that the latch 100 of the present application does not require the aid of external tools, and only requires applying a driving force to the unlocking member 40 so that the latch 100 can be quickly separated from the mating member 200, thereby meeting the requirements of convenience, time saving and labor saving.

[0054] See also Figure 5 , Figure 6 and Figure 7In order to facilitate understanding of the detachable connection between the buckle 100 and the mating member 200, the structure of the mating member 200 is described. In the embodiment of the present application, the mating member 200 is taken as a watch strap for example. The end of the mating member 200 has a second end face 210. The second end face 210 is provided with a concave slot 220. The slot 220 is plugged into the protrusion 12, and the inner side surface of the slot 220 is provided with a slot 230 corresponding to the opening of the groove 121. When the second end face 210 abuts against the first end face 11, the hook end 21 is inserted into the slot 230. A through slot 240 connected to the slot 220 is further provided on one side of the mating piece 200 facing away from the card slot 230. The through slot 240 and the portion of the protrusion 12 that exposes the unlocking piece 40 are slidably matched, so that when the latch 100 and the mating piece 200 are plugged in, the unlocking piece 40 exposes the through slot 240, thereby facilitating the application of an unlocking force to the unlocking piece 40, and further allowing the mating piece 200 and the latch 100 to be disassembled.

[0055] For further information, see Figure 8 , Fig. 9 and Fig.10 , the hook end 21 has a resisting surface 211 and a first inclined surface 212 or a first curved surface opposite to the resisting surface 211. When the buckle 100 is engaged with the mating member 200, the resisting surface 211 is used to hook the mating member 200. When the buckle 100 is partially engaged with the mating member 200, the mating member 200 slides along the first inclined surface 212 or the first curved surface, and presses the hook 20 into the groove, and continues to move toward the first end surface. In this embodiment, the resisting surface 211 and the first inclined surface 212 or the first curved surface are arranged at the portion of the hook end 21 that can extend out of the groove 121. The resisting surface 211 is substantially perpendicular to the extension direction of the protrusion 12 to prevent the mating member 200 from sliding along the extension direction of the protrusion 12. When the abutting surface 211 abuts against the inner side surface of the locking groove 230 , the first end surface 11 abuts against the second end surface 210 , and the matching component 200 and the buckle component 100 maintain a stable state.

[0056] In this embodiment, the first inclined surface 212 or the first arcuate surface is away from the first end surface 11 relative to the abutting surface 211, wherein when the unlocking member 40 does not drive the free end 22, the first inclined surface 212 or the first arcuate surface partially sinks into the groove 121. The first inclined surface 212 is set at an angle to the abutting surface 211. The distance from the edge of the first inclined surface 212 close to the opening of the groove 121 to the abutting surface 211 is greater than the distance from the edge of the first inclined surface 212 far from the opening of the groove 121 to the abutting surface 211, so that during the plug-in process of the mating member 200 and the connecting body 10, since the first inclined surface 212 partially sinks into the groove 121, it is convenient for the end of the mating member 200 to slide directly to the first inclined surface 212 along the side of the protrusion 12, avoiding the presence of a raised step between the first inclined surface 212 and the side of the protrusion 12, and facilitating the end of the mating member 200 to slide along the first inclined surface 212 and press the hook end 21 The second end face 210 of the mating piece 200 is inserted into the groove 121, so that the second end face 210 of the mating piece 200 continues to move closer to the first end face 11. After the second end face 210 abuts against the first end face 11, the hook end 21 just corresponds to the groove 230, so that the hook end 21 is no longer subjected to the pressure of the mating piece 200 in the direction perpendicular to the side of the protrusion 12, so that the hook end 21 rebounds to a state of extending relative to the groove 121 under the driving of the driving member 30, and the abutting surface 211 cooperates with the inner side surface of the groove 230, so that the hook end 21 hooks the mating piece 200, thereby making the mating piece 200 and the buckle 100 stable. By providing the first inclined surface 212 on the hook end 21, it is convenient to insert the fitting 200 into the fastener 100 without applying a pressing driving force to the hook end 21, so that the hook end 21 can be automatically inserted into the slot 230, so that the fitting 200 and the fastener 100 can be quickly and firmly assembled. Of course, in other embodiments, the first inclined surface 212 can be replaced by a first curved surface. The first curved surface is a curved surface convex outward. The distance from the edge of the first curved surface adjacent to the opening of the groove 121 to the abutting surface 211 is greater than the distance from the edge of the first curved surface away from the opening of the groove 121 to the abutting surface 211.

[0057] For further information, see Fig. 9 , Fig.10 and Fig.11 The hook end 21 also has a top end surface 213 connecting the first inclined surface 212 or the first arc surface and the blocking surface 211. When the unlocking member 40 is not driven to the free end 22, the top end surface 213 is parallel to the side surface of the protrusion 12 where the groove 121 is opened.

[0058] In this embodiment, the top end surface 213 is substantially perpendicular to the abutment surface 211. When the hook end 21 is in a state of extending out of the groove 121, the top end surface 213 is parallel to the side surface of the protrusion 12 that opens the groove 121, so that during the process of inserting the protrusion 12 into the slot 220, the top end surface 213 reduces the insertion resistance to the matching piece 200, and facilitates the protrusion 12 to be quickly inserted into the slot 220. The top end surface 213 is a flat surface, so that the distance from the abutment surface 211 to the first inclined surface 212 can be increased to increase the structural strength of the hook end 21 and ensure the connection stability between the buckle 100 and the matching piece 200. Of course, in other embodiments, the top end surface 213 can also be set as a circular arc surface.

[0059] Furthermore, the protrusion 12 is provided with a rotating shaft 122 located in the groove 121, the rotating arm 23 is rotatably connected to the rotating shaft 122, and the portion of the rotating arm 23 close to the hook end 21 is relatively far away from the bottom wall of the groove 121 relative to the portion close to the rotating shaft 122. The hook member 20 has a rotating back surface 24 extending from the rotating arm 23 to the hook end 21, and when the unlocking member 40 is not driven on the hook end 21, the edge of the rotating back surface 24 close to the hook end 21 is relatively far away from the bottom wall of the groove 121 relative to the edge of the rotating back surface 24 close to the rotating shaft 122, so that the distance from the hook end 21 to the bottom wall of the groove 121 is greater than the retracted stroke of the hook end 21.

[0060] In this embodiment, the rotating back surface 24 is inclined relative to the top end surface 213. The rotating back surface 24 is disposed on the side of the hook member 20 away from the opening of the groove 121. The edge of the rotating back surface 24 adjacent to the rotating shaft 122 has a smaller rotation radius, while the edge of the rotating back surface 24 adjacent to the hook end 21 has a larger rotation radius. In order to allow the hook end 21 to have a sufficient rotation stroke, that is, to ensure that the hook end 21 has a sufficient extension and retraction stroke, it is necessary to set the distance from the edge of the rotating back surface 24 adjacent to the hook end 21 to the bottom wall of the groove 121 to be much greater than the distance from the edge of the rotating back surface 24 adjacent to the rotating shaft 122 to the bottom wall of the groove 121. The rotating back surface 24 is a flat surface. When the hook end 21 is retracted into the groove 121, the rotating back surface 24 is substantially parallel to the bottom wall of the groove 121 and substantially adjacent to the bottom wall of the groove 121, so as to reduce the space of the groove 121, thereby reducing the thickness of the protrusion 12 and ensuring the slimness of the buckle 100. Since the rotating back surface 24 is inclined relative to the top end surface 213, the thickness of the rotating arm 23 adjacent to the hook end 21 is smaller than the thickness of the rotating arm 23 adjacent to the shaft hole 231, thereby ensuring that the inner diameter of the shaft hole 231 is large enough, and the outer diameter of the shaft 122 can be large enough to ensure the rotational matching strength between the hook member 20 and the shaft 122.

[0061] In one embodiment, the driving member 30 is a spring, one end of which is fixedly connected to the hook end 21 , and the other end of which is abutted against the bottom wall of the groove 121 to provide elastic restoring force for the hook end 21 to extend out of the groove 121 .

[0062] Specifically, a fixing groove 241 is provided on the rotating back surface 24 corresponding to the hook end 21. A part of the driving member 30 is fixed in the fixing groove 241 to ensure the connection strength between the driving member 30 and the hook member 20, and to ensure that the driving force of the driving member 30 is effectively driven on the hook end 21, so that when the unlocking member 40 does not drive the hook member 20, the hook end 21 can continue to extend out of the groove 121. The driving member 30 can be in a naturally stretched state when the unlocking member 40 does not drive the free end 22, so that the hook end 21 can maintain a state of extending out of the groove 121 under the drive of the elastic restoring force of the driving member 30. When the unlocking member 40 drives the free end 22, the free end 22 is pushed up toward the opening of the groove 121, and the hook end 21 is retracted toward the bottom wall of the groove 121, so that the driving member 30 is in a compressed state under the retraction of the hook end 21. Of course, in other embodiments, the rotating back surface 24 may be provided with a fixing protrusion 12 , and a portion of the driving member 30 may be fixedly connected to the fixing protrusion 12 .

[0063] In another embodiment, see Fig.12 ,and Fig. 9 The illustrated embodiments are substantially the same, except that the driving member 30 includes a first magnetic block 31 fixed to the hook end 21 and a second magnetic block 32 fixed to the bottom wall of the groove 121, the first magnetic block 31 and the second magnetic block 32 repel each other, and the magnetic force of the first magnetic block 31 and the second magnetic block 32 drives the hook end 21 to extend out of the groove 121.

[0064] Specifically, the first magnetic block 31 is fixed in the fixing groove 241, and the first magnetic block 31 exposes the fixing groove 241 on one side facing the bottom wall of the groove 121. The second magnetic block 32 is fixed at the bottom wall of the groove 121 directly opposite to the hook end 21, so that the first magnetic block 31 and the second magnetic block 32 are magnetically repelled, and the first magnetic block 31 is driven by the magnetic repulsion to drive the hook end 21 to move toward the state of extending out of the opening of the groove 121. When the unlocking member 40 does not drive the free end 22, the first magnetic block 31 and the second magnetic block 32 are magnetically repelled, and the hook end 21 continues to extend out of the groove 121 under the drive of the magnetic repulsion. When the unlocking member 40 drives the free end 22, the free end 22 overcomes the magnetic repulsion and is driven to rise toward the opening of the groove 121, the first magnetic block 31 and the second magnetic block 32 are brought close to each other, and the hook end 21 is retracted into the groove 121.

[0065] Please continue reading Fig. 9 , Fig.10 and Fig.11In one embodiment, the unlocking member 40 is a button, a portion of the unlocking member 40 extends into the groove 121, and the other portion is exposed to the surface of the protrusion 12, and the unlocking member 40 exposes a portion of the surface of the protrusion 12 to receive the pressing force, so that the unlocking member 40 drives the free end 22 to rotate toward the opening of the groove 121.

[0066] Specifically, a button hole 123 connected to the groove 121 is provided on one side of the protrusion 12 away from the opening of the groove 121, and the unlocking member 40 passes through the button hole 123 and abuts against the free end 22. The unlocking member 40 includes a pressing portion 41 and a resisting portion 42 fixed to the pressing portion 41. The pressing portion 41 cooperates with the button hole 123. The resisting portion 42 abuts against the free end 22. The width of the resisting portion 42 is greater than the width of the pressing portion 41, and the resisting portion 42 is accommodated in the groove 121, thereby preventing the unlocking member 40 from being separated from the groove 121 and ensuring that the unlocking member 40 is effectively pressed. The side of the pressing portion 41 away from the resisting portion 42 exposes the button hole 123, or is flush with the side of the protrusion 12 away from the opening of the groove 121, so that the unlocking member 40 can receive the pressing force.

[0067] More specifically, two rotating shafts 122 are arranged in the groove 121, and the two rotating shafts 122 are parallel. The buckle 100 includes two hook members 20, and the two hook members 20 are respectively rotatably matched with the two rotating shafts 122. The two free ends 22 are close to each other, and the two hook ends 21 are far away from each other. The two sides of the abutment 42 are respectively abutted against the two free ends 22. When the pressing portion 41 receives the pressing force, the abutment 42 simultaneously pushes the two free ends 22 toward the opening of the groove 121, so that the two hook ends 21 are simultaneously retracted into the groove 121, thereby completely unlocking and disengaging the protrusion 12 from the slot 220 of the mating member 200. When the pressing portion 41 does not receive the pressing force, the two hook ends 21 extend out of the groove 121 at the same time, and the two hook ends 21 jointly clamp and hook the matching member 200 , thereby increasing the clamping stability between the buckle 100 and the matching member 200 .

[0068] In this embodiment, a second inclined surface 221 or a second curved surface is provided on one side of the free end 22 adjacent to the bottom wall of the groove 121, and the second inclined surface 221 or the second curved surface cooperates with the end of the unlocking member 40 to receive the driving force of the unlocking member 40 and enables the free end 22 to rotate around the rotating shaft 122. The distance from the edge of the second inclined surface 221 or the second curved surface close to the rotating shaft 122 to the bottom wall of the groove 121 is smaller than the distance from the edge of the second inclined surface 221 or the second curved surface away from the rotating shaft 122 to the bottom wall of the groove 121, so that the free end 22 can rotate around the rotating shaft 122 under the pressure of the abutment 42. More specifically, a third inclined surface 43 or a third curved surface that is slidably matched with the second inclined surface 221 or the second curved surface is provided at the end of the unlocking member 40. In this embodiment, the third inclined surface 43 or the third arc surface is arranged at the opposite ends of the resistance portion 42, so that the resistance portion 42 can drive the two free ends 22 at the same time, and the resistance portion 42 can transmit the pressing driving force perpendicular to the bottom wall direction of the groove 121 to the free end 22, thereby converting it into a torque that causes the free end 22 to rotate around the rotating shaft 122.

[0070] Specifically, the unlocking member 40 is rotatably connected to the protrusion 12, and the cam 44 is received in the groove 121. The portion of the unlocking member 40 that is exposed from the protrusion 12 is located at the portion of the protrusion 12 that is away from the opening of the groove 121. When the length direction of the cam 44 is rotated to a direction perpendicular to the rotation axis 122, the cam 44 pushes up the two free ends 22, so that the two hook ends 21 are retracted into the groove 121. When the length direction of the cam 44 is rotated to a direction parallel to the rotation axis 122, the two free ends 22 move toward the bottom wall of the groove 121, so that the hook ends 21 extend out of the groove 121.

A slide groove 129 is disposed on the side of the protrusion 12 that is away from the opening of the groove 121, and a portion of the unlocking member 40 is slidably engaged with the slide groove 129. The sliding direction of the unlocking member 40 is parallel to the axis of the rotating shaft 122. When the push-up block 45 slides to a direction facing the two free ends 22, the push-up block 45 lifts the two free ends 22, so that the hook end 21 is retracted into the groove 121. When the push-up block 45 slides to be offset from the two free ends 22, the free end 22 moves toward the bottom wall of the groove 121, so that the hook end 21 extends out of the groove 121.
