When the driving member operates, the steel balls can extend into the circular grooves to drive the transmission gear to rotate, so that the clutch push plate makes a reciprocating movement;

[0008] Shaft piece meshing structure, the shaft piece meshing structure is arranged adjacent to the clutch transmission structure, and includes a handle return piece, a handle shaft, an unlocking component and a clutch pin. The handle shaft is connected to the middle of the handle return piece. The handle return piece is movably connected to the unlocking component. A first control port is formed at the edge of the handle return piece. A fixing frame is arranged on the first control port. A second control port is formed on the fixing frame. The clutch pin is movably arranged on the fixing frame. A second spring is also sleeved on the clutch pin so that the end of the clutch pin extends out of the second control port. The clutch push plate can push one end of the clutch pin extending out of the second control port so that the other end extends out of the first control port and is clamped with the unlocking component.

[0009] In an embodiment of the present invention, the unlocking component includes:

[0010] An unlocking piece, the unlocking piece is attached and connected to the handle return piece;

[0011] An unlocking shaft, the unlocking shaft penetrates through the middle of the unlocking piece.

[0012] In an embodiment of the present invention, a part of the edge of the unlocking piece extends outwards to form a clamping part, and clamping grooves are formed at both ends of the clamping part. The clutch pin can abut against the clamping grooves.

[0013] In an embodiment of the present invention, a connection port is formed in the middle of the unlocking piece, and a plurality of protrusions are convexly arranged on the edge of the connection port. A connection ring is circumferentially arranged at one end of the unlocking shaft, and a recessed part is arranged on the connection ring corresponding to the protrusion.

[0014] In an embodiment of the present invention, the thickness of the handle return piece and the unlocking piece is less than or equal to 2 mm.

[0015] In an embodiment of the present invention, the clutch transmission structure further includes a protective shell, and an installation cavity is formed in the protective shell, and the driving part, the clutch cam, the steel ball and the transmission gear are covered in the installation cavity.

[0016] In an embodiment of the present invention, the clutch push plate includes a sliding block and an arc-shaped plate connected to each other.

It is characterized in that the clutch is provided with the intelligent lock clutch mechanism as described in any one of the above.

[0020] In the technical solution of the present utility model, the driving force of the driving member is transmitted to the clutch cam. The first spring installed inside the clutch cam ejects the steel ball. The steel ball rubs against the circular groove of the transmission gear. Under the action of the frictional force, the transmission gear rotates together with the clutch cam. The transmission gear meshes with the toothed part of the clutch push plate and drives the clutch push plate to move up and down. When the clutch push plate moves to the unlocking or locking fixed position, the clutch push plate stops working. At this time, the driving member still rotates, and the steel ball will slip with the transmission gear, thus protecting the motor from being damaged due to overload.

[0021] The clutch push plate moves in the unlocking direction, pushing the clutch pin to extend out of the first control port and engage with the unlocking piece. At this time, when the handle return piece rotates, it will drive the unlocking piece and the unlocking shaft to rotate and unlock. The clutch push plate moves in the locking direction. Under the action of the second spring, the clutch pin rebounds out of the second control port and disengages from the unlocking piece. At this time, when the handle return piece is rotated, it will not drive the unlocking piece and the unlocking shaft to unlock. The shaft piece meshing structure adopts two 2-mm-thick steel plate stamping parts, which not only reduces the thickness of the clutch to a very extreme state, but also has great advantages in terms of cost, processing technology, and production efficiency.

[0031] The realization, functional features and advantages of the purpose of the present utility model will be further described with reference to the embodiments and the attached drawings. Detailed implementation manners

[0032] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] Refer to Figures 1 to 4, the present utility model proposes an intelligent lock clutch mechanism, including a driving member 1, a clutch transmission structure, and a shaft piece meshing structure; the clutch transmission structure includes a clutch cam 2, a steel ball 3, a transmission gear 4, and a clutch push plate 5. The clutch cam 2 is connected to the driving member 1, the transmission gear 4 is disposed in contact with the clutch cam 2, the clutch cam 2 is provided with a spring hole 21 on the contact surface with the transmission gear 4, a first spring 22 is disposed in the spring hole 21, the steel ball 3 abuts against the first spring 22, the clutch push plate 5 has a toothed portion 51, the toothed portion 51 meshes with the transmission gear 4, and a plurality of circular grooves 41 are circumferentially disposed on the contact surface of the transmission gear 4 with the clutch cam 2. When the driving member 1 operates, the steel ball 3 can extend into the circular groove 41 to drive the transmission gear 4 to rotate, so that the clutch push plate 5 makes a reciprocating movement; the shaft piece meshing structure is disposed adjacent to the clutch transmission structure, and includes a handle return piece 6, a handle shaft 64, an unlocking assembly 7, and a clutch pin 8. The handle shaft 64 is connected to the middle of the handle return piece 6, the handle return piece 6 is movably connected to the unlocking assembly 7, a first control port 61 is opened on the edge of the handle return piece 6, a fixing bracket 62 is disposed on the first control port 61, a second control port 63 is opened on the fixing bracket 62, the clutch pin 8 is movably disposed in the fixing bracket 62, and a second spring 81 is further sleeved on the clutch pin 8 so that the end of the clutch pin 8 extends out of the second control port 63. The clutch push plate 5 can push one end of the clutch pin 8 extending out of the second control port 63 so that the other end extends out of the first control port 61 and is engaged with the unlocking assembly 7.

[0034] Understandably, the driving member 1 provides power for locking and unlocking, and can be a conventional servo motor, a variable speed motor and other devices. In this example, the driving member 1 is a planetary reduction motor, which can reduce the speed of the motor and increase the output torque at the same time.

[0035] The clutch drive structure converts the rotational power provided by the motor into the reciprocating translational power of the clutch push plate 5. The clutch cam 2 is connected to the output shaft of the drive member 1, and the transmission gear 4 is in frictional contact with the clutch cam 2. At the same time, there are steel balls 3 on the contact surface between the two. In this example, a spring hole 21 is formed on the contact surface of the clutch cam 2, and a first spring 22 is placed in the spring hole 21. The steel ball 3 abuts against the first spring 22. The first spring 22 can generate a thrust on the steel ball 3 to make it press into the circular groove 41 formed on the transmission gear 4. At the same time, the steel ball 3 can also compress the first spring 22 when being extruded and retract into the spring hole 21. A circular groove 41 is formed in a circle on the contact surface of the transmission gear 4 with the clutch cam 2, and the steel ball 3 can extend into any one of the circular grooves 41. When the drive member 1 operates, the steel ball 3 extending into the circular groove 41 drives the transmission gear 4 to rotate, and the transmission gear 4 drives the clutch push plate 5 engaged with it to move to achieve unlocking / locking. When the clutch push plate 5 moves to the fixed position of unlocking or locking, the clutch push plate 5 stops moving. However, at this time, the drive member 1 still rotates, and the steel ball 3 will retract into the spring hole 21 under the pressing action of the inner wall of the circular groove 41. At this time, the steel ball 3 will slip with the transmission gear 4, thus protecting the motor from being damaged due to overload and jamming.

[0036] The shaft piece meshing structure is the structure for realizing unlocking / locking. The handle shaft 64 is usually connected to an external handle, and the handle shaft 64 is further connected to the handle reset piece 6. By rotating the handle, the handle reset piece 6 can be manipulated to rotate. The unlocking assembly 7 is in frictional contact with the handle reset piece 6 and can rotate relative to the handle reset piece 6. A first control port 61 is formed at the edge position of the handle reset piece 6 corresponding to the clutch push plate 5, and the fixing bracket 62 is also installed at the position of the first control port 61. At the same time, a second control port 63 is formed on the fixing bracket 62 corresponding to the first control port 61. The clutch pin 8 is inserted into the fixing bracket 62 and can move, and its two ends can respectively extend out of the first control port 61 and the second control port 63. At the same time, a second spring 81 is sleeved on the part of the clutch pin 8 inside the fixing bracket 62. The second spring 81 can keep one end of the clutch pin 8 extending out of the second control port 63 when the clutch pin 8 is not subjected to external force. In this state, when the handle reset piece 6 is rotated, the unlocking assembly 7 will not move, and thus unlocking cannot be achieved. When unlocking is required, the clutch push plate 5 will move and push the end of the clutch pin 8 extending out of the second control port 63, so that the other end extends out of the first control port 61, and the extended part will be caught with the unlocking assembly 7. At this time, when the handle reset piece 6 is rotated, the clutch pin 8 will drive the unlocking assembly 7 to rotate to achieve unlocking. After unlocking is completed, the clutch push plate 5 gradually moves away from the clutch pin 8, and the clutch pin 8 rebounds and extends out of the second control port 63 under the action of the second spring 81, and is disengaged from the catching state with the unlocking assembly 7.

[0037] Refer to Figure 2, in an embodiment of the present application, the unlocking assembly 7 includes an unlocking piece 71 and an unlocking shaft 72. The unlocking piece 71 is adhesively connected to the handle reset piece 6; the unlocking shaft 72 is disposed through the middle of the unlocking piece 71.

[0038] It can be understood that the unlocking piece 71 is in contact with the handle reset piece 6, and the two can rotate relative to each other. When the clutch pin 8 extends out of the first control port 61, it can be engaged with the unlocking piece 71. The specific way of engagement can be that the unlocking piece 71 also has a hole at the position of the first control port 61. When the clutch pin 8 extends out of the first control port 61, it will also extend into this hole to complete the engagement. Or, a groove is formed at the position of the unlocking piece 71 close to the first control port 61. When the clutch pin 8 extends out of the first control port 61, it will fit into this groove. When the handle reset piece 6 is rotated, the clutch pin 8 will drive the unlocking piece 71 and the unlocking shaft 72 disposed through the middle of the unlocking piece 71 to rotate, completing the unlocking.

[0039] Refer to Figure 2 , in an embodiment of the present application, a clamping portion 711 is formed by extending a part of the edge of the unlocking piece 71 outward. Clamping grooves 712 are formed at both ends of the clamping portion 711, and the clutch pin 8 can be abutted against the clamping grooves 712.

[0040] It can be understood that the clamping portion 711 is a protruding part formed by extending a part of the edge of the unlocking piece 71. Crescent-shaped clamping grooves 712 are formed at both ends of the clamping portion 711. When the clutch pin 8 extends out of the first control port 61, it can just come into contact with the clamping grooves 712. When the handle reset piece 6 is rotated, the clutch pin 8 will push the clamping grooves 712, causing the unlocking piece 71 and the unlocking shaft 72 to rotate and unlock.

[0041] Refer to Figure 2 , in an embodiment of the present application, a connection port 713 is provided in the middle of the unlocking piece 71. A plurality of protrusions are convexly provided on the edge of the connection port 713. A connection ring 721 is circumferentially provided at one end of the unlocking shaft 72, and a recess 722 is provided on the connection ring 721 corresponding to the protrusion.

[0042] Understandably, the unlocking piece 71 and the unlocking shaft 72 are engaged with each other through the protruding part 714 and the recessed part 722. This method has the following advantages: Simplify assembly and disassembly. The design of the protruding part 714 and the recessed part 722 enables them to be easily docked and separated without complex tools or additional fasteners. The fast and intuitive assembly method improves production efficiency and reduces assembly time; Provide a stable connection. The engagement method of the protruding part 714 and the recessed part 722 can provide a firm connection, preventing the components from loosening or displacing during use. Through this engagement design, the sliding or misalignment between the unlocking piece 71 and the unlocking shaft 72 can be effectively prevented, improving the stability of the connection; Improve accuracy. The design of the protruding part 714 and the recessed part 722 can help the components to be accurately docked, ensuring that they are in the correct positions, reducing assembly errors, providing good fitting accuracy, and reducing potential problems caused by misalignment of the components.

[0043] Referring to Figure 2 , in an embodiment of the present application, the thickness of the handle reset piece 6 and the unlocking piece 71 is less than or equal to 2 mm.

[0044] Understandably, in this example, both the handle reset piece 6 and the unlocking piece 71 are made of steel, and their thicknesses are both 2 mm. It can take into account the structural strength while greatly reducing the thickness of the entire smart lock. Most of the smart locks on the market currently have a thickness of more than 20 mm. For the smart lock equipped with the clutch mechanism of this embodiment, by using two 2-mm-thick steel plate stampings, not only the thickness of the clutch 12 is thinned to a very extreme state, but also the thickness of the smart lock can be realized within 14 mm, which is more than 6 mm thinner than most of the existing smart locks currently. At the same time, it has great advantages in terms of cost, processing technology, and production efficiency. The thinner smart lock is also more aesthetically pleasing.

[0045] Referring to Figure 3 , in an embodiment of the present application, the clutch transmission structure further includes a protective shell 9. An installation cavity is formed in the protective shell 9, and the driving member 1, the clutch cam 2, the steel ball 3, and the transmission gear 4 are covered therein.

[0046] Understandably, the protective shell 9 covers some components of the clutch transmission structure. The driving member 1, the clutch cam 2, and the transmission gear 4 are sequentially installed in the protective shell 9. The layout is compact and space-saving, making the volume of the entire protective shell 9 smaller, increasing the aesthetic appearance of the smart lock. At the same time, the protective shell 9 also provides good protection for the components installed in the installation cavity, preventing them from being damaged by external collisions. In this example, the protective shell 9 is provided in a split form and is assembled by two different components, which is convenient for disassembly, installation, and maintenance of the internal components.

[0047] Referring to Figure 3, in an embodiment of the present application, the clutch push plate 5 includes a sliding block 52 and an arc plate 53 connected to each other. Sliding grooves 521 are provided at both ends of the sliding block 52, and sliding bars 91 corresponding to the sliding grooves 521 are provided on the protective housing 9.

[0048] It can be understood that the clutch push plate 5 is composed of a sliding block 52 connected to the protective housing 9 and an arc plate 53 connected to the sliding block 52. The shape of the arc plate 53 coincides with the edge shape of the handle return piece 6. The sliding block 52 and the protective housing 9 are connected by the sliding grooves 521 and the sliding bars 91. In addition to being able to connect the clutch push plate 5 to the protective housing 9, it can also limit the displacement direction of the clutch push plate 5, so that it can only make reciprocating displacements along the direction of the sliding bars 91 without generating displacements in other directions, which helps to improve the stability of the movement process and reduce mechanical wear.

[0049] Refer to Figure 3 , in an embodiment of the present application, the length of the sliding bar 91 is greater than the length of the sliding groove 521.

[0050] It can be understood that the length of the sliding bar 91 should be longer than the length of the sliding groove 521 so that the sliding groove 521 has enough space for displacement, and the displacement distance is equal to the distance obtained by subtracting the length of the sliding groove 521 from the length of the sliding bar 91. Changing the lengths of the sliding groove 521 and the sliding bar 91 can adjust the moving distance of the clutch push plate 5. This method requires a simple structure, is easy to produce, and is simple and practical.

[0051] Refer to Figure 3 , in an embodiment of the present application, a clutch shaft 31 is connected between the clutch cam 2 and the transmission gear 4, and the clutch shaft 31 is in interference or transitional fit with the clutch cam 2, and the clutch shaft 31 is in clearance fit with the transmission gear 4.

[0052] It can be understood that the clutch shaft 31 connects the clutch cam 2 and the transmission gear 4 together to form a component. Connecting holes are provided on both the clutch cam 2 and the transmission gear 4, and the connecting hole on the clutch shaft 31 and the clutch cam 2 is in interference fit in this example, with a relatively tight connection, while the connecting hole on the clutch shaft 31 and the transmission gear 4 is in clearance fit, which can not affect the idling of the driving member 1. At the same time, the clutch shaft 31 enables the clutch cam 2 and the transmission gear 4 to be maintained on the same rotation axis, which helps to maintain the stability during the movement process.

[0053] In the technical solution of the present utility model, the rotational force of the driving member 1 is transmitted to the clutch cam 2, the first spring 22 installed in the clutch cam 2 pushes out the steel ball 3, and the steel ball 3 rubs against the circular groove 41 of the transmission gear 4. Under the action of the frictional force, the transmission gear 4 rotates together with the clutch cam 2. The transmission gear 4 meshes and drives with the toothed portion 51 of the clutch push plate 5, driving the clutch push plate 5 to move up and down. When the clutch push plate 5 moves to the unlocking or locking fixed position, the clutch push plate 5 stops working. At this time, the driving member 1 still rotates, and the steel ball 3 will slip with the transmission gear 4, thereby protecting the motor from being damaged by overload.

[0054] The clutch push plate 5 moves in the unlocking direction, pushing the clutch pin 8 to extend out of the first control port 61 and engage with the unlocking piece 71. At this time, when the handle return piece 6 rotates, it will drive the unlocking piece 71 and the unlocking shaft 72 to rotate to unlock. The clutch push plate 5 moves in the locking direction. Under the action of the second spring 81, the clutch pin 8 rebounds out of the second control port 63 and disengages from the unlocking piece 71. At this time, when the handle return piece 6 is rotated, it will not drive the unlocking piece 71 and the unlocking shaft 72 to unlock. The shaft piece meshing structure adopts two 2-mm-thick steel plate stamping parts, which not only reduces the thickness of the clutch 12 to a very extreme state, but also has great advantages in terms of cost, processing technology, and production efficiency.

[0055] Referring to Figures 5 to 6 , the present utility model also proposes an intelligent lock, which includes a housing 11, a clutch 12 installed inside the housing 11, and a handle 13 connected to the clutch 12. The specific structure of the clutch 12 refers to the above-mentioned embodiment. Since this intelligent lock adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated here one by one. In addition, the intelligent lock can also be provided with a front panel 14, a circuit board 19 for controlling unlocking and locking, a rechargeable battery for providing electric energy, a front cover plate 15, a connecting screw rod connected to the front cover plate 15, and a square shaft installed on the unlocking shaft 72, etc. according to the user's usage requirements. On the other side of the door, a rear panel 16, a rear cover plate 17, a decorative piece 18, etc. connected to the front panel 14 can be provided. The decorative piece 18 can be connected to the rear cover plate 17 by a magnet, so that the installation screws are not exposed.
