Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, and in particular to a smart lock clutch motor assembly. Background Technology

[0002] In smart locks, a clutch motor and transmission mechanism are typically used to move the lock body push block, controlling its movement in and out of the lock slot and to the desired position. When the motor needs to rotate to unlock or lock, it connects to the transmission mechanism. When the motor is not needed or manual operation is required, it disengages. When the clutch motor is connected to the transmission mechanism, it rotates, driving the lock body push block through the transmission mechanism. In case of smart control failure or battery depletion, the clutch motor disconnects from the transmission mechanism, allowing the user to manually operate the lock.

[0003] For example, Chinese utility model patent No. 2020224088138 discloses a self-locking intelligent lock clutch drive device, characterized in that it includes a base, an arc-shaped push block disposed in the base, an electric drive assembly disposed on one side of the arc-shaped push block, and a manual drive assembly disposed on the other side of the arc-shaped push block. The base includes a first cavity for installing the manual drive assembly, a second cavity for installing the arc-shaped push block, and a third cavity for installing the electric drive assembly. A crossbar and a baffle for limiting the arc-shaped push block are rotatably disposed inside the second cavity. The crossbar includes a crossbar body, a limiting shaft fixedly disposed in the middle of the crossbar body, and a driven gear disposed at the end of the crossbar body. The arc-shaped push block includes an arc-shaped part integrally formed from top to bottom, a movable cavity sleeved on the baffle, and a... The "L"-shaped slide has a crossbar that passes through the movable cavity and is positioned between the baffle and the slide. A drive spring is fitted on the crossbar body between the baffle and the movable cavity, and the drive spring is limited to the crossbar by a limiting shaft. The electric drive assembly includes an electric motor fixedly installed in the second cavity and a drive gear located at the output end of the electric motor and meshing with the driven gear. The manual drive assembly includes a guide hole fixedly installed on one side of the seat, a push rod assembly passing through the guide hole, and a return spring fitted on the push rod assembly. The push rod assembly includes a push rod body, a first limiting part and a second limiting part installed on the push rod body, and a steering block installed at the tail of the push rod body. The first limiting part is also fixedly provided with a locking part that locks both the manual drive assembly and the electric drive assembly simultaneously by steering.

[0004] The aforementioned intelligent lock clutch motor structure integrates an electric drive component and a manual drive component on the other side into a single housing. However, when using this structure, the housing needs to be installed into the clutch housing, which requires corresponding mounting holes and screws between the housing and the clutch housing for fixation. This results in high costs and complicated installation. Furthermore, the aforementioned electric drive component structure is quite complex, thus requiring improvement. Utility Model Content

[0005] This utility model aims to solve the technical problems of existing intelligent lock clutch motors, which are cumbersome to install, costly, have complex transmission structures, and lack reliability in emergency operation due to the separation of the clutch motor base and clutch housing. It provides an integrated, high-efficiency transmission, dual-drive compatible clutch motor assembly.

[0006] This application provides an intelligent lock clutch motor assembly, including a clutch housing with a mounting groove. The mounting groove is characterized in that a manual groove for accommodating a manual drive component and an electric groove for accommodating an electric drive component are respectively provided on the left and right sides of the lower middle part of the mounting groove, and a cover plate for limiting the manual drive component and the electric drive component is provided at the manual groove and the electric groove.

[0007] Preferably, a first hole is provided in the lower middle part of the mounting groove, and a second hole is provided on the cover plate. After the cover plate is placed on the electric groove and the manual groove, it is fixed by a first screw in conjunction with the first hole and the second hole.

[0008] Preferably, two limiting posts are provided in the mounting groove on the side away from the manual groove and the electric groove to limit the left and right side walls of the cover plate.

[0009] Preferably, each of the two limiting posts has a limiting post hole for installing another clutch housing.

[0010] Preferably, the electric drive assembly includes an electric motor installed in the electric slot and a drive gear disposed at the output end of the electric motor. A central shaft is rotatably disposed on the cover plate between the electric drive assembly and the manual drive assembly. A central gear is disposed on the central shaft. The central gear and the drive gear are connected by a driven gear transmission. An arc-shaped push block is connected to the central shaft by a rotating lifting assembly.

[0011] Preferably, the rotating lifting assembly includes a housing connected to an arc-shaped push block at the top, a fixed plate inside the housing, and a central rotating shaft extending from one end away from the central gear through the bottom of the housing and the fixed plate to the top of the housing. A strip-shaped hole is provided on the side wall of the housing below the fixed plate. A horizontal fixed column is provided on the central rotating shaft. A coiled spring is wound on the central rotating shaft between the bottom of the housing and the fixed plate. The upper and lower ends of the coiled spring extend into the strip-shaped hole, and the fixed column extends horizontally through the coiled spring. When the central rotating shaft rotates, it drives the fixed column to push the coiled spring up and down. A lifting groove for raising and lowering the housing is provided between the manual groove and the electric groove in the lower middle part of the mounting groove.

[0012] Preferably, the clutch housing has a housing strip-shaped hole into which the upper and lower ends of the coiled spring extend, and the side wall of the housing has a notch located below the fixing plate.

Several guide blocks extend from the side wall of the driven post into the corresponding arc-shaped guide grooves. Several sliding guide blocks are provided on the side wall of the driven post. The manual slot and / or the cover plate have corresponding sliding guide holes. As the rotating body rotates in both directions, the sliding guide blocks slide along the sliding guide holes through the arc-shaped guide grooves and guide blocks, driving the driven post to rise and fall. A spring is provided between the upper end of the driven post and the bottom of the arc-shaped push block, located at the outlet. A limit block is provided on the lower side wall of the rotating body. A limit groove is provided on the cover plate for the limit block to slide within it.

The driven post is provided with two symmetrical guide blocks, which are arranged in the shape of vertical strips and are correspondingly arranged in the arc-shaped guide grooves.

[0016] The above-mentioned intelligent lock clutch motor assembly features an integrated layout that reduces redundant components: the manual and electric drive components are directly separated in the mounting slot of the clutch housing, integrating the manual drive component and the electric drive component into the same housing, eliminating the need for an additional independent base (compared to the dual structure of base + clutch housing in the prior art), reducing the number of parts and lowering processing and material costs.

[0017] The beneficial effects of this invention will be explained in detail in the embodiments, thereby making the beneficial effects more obvious. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0029] Example 1: like Figure 1As shown, an intelligent lock clutch motor assembly includes a clutch housing 1 with a mounting groove 2. In a specific embodiment of this utility model, the lower left and right sides of the mounting groove 2 are respectively provided with a manual groove 3 for accommodating a manual drive component and an electric groove 4 for accommodating an electric drive component. The manual groove 3 and the electric groove 4 are covered with cover plates 5 for limiting the manual drive component and the electric drive component.

[0030] By adopting the above technical solution, the integrated layout reduces redundant components: the manual drive slot 3 and the electric drive slot 4 are directly set in the mounting slot 2 of the clutch housing 1, integrating the manual drive component and the electric drive component into the same housing, eliminating the need for an additional independent seat (compared to the dual structure of seat + clutch housing in the prior art), reducing the number of parts and lowering processing and material costs.

[0031] In a specific embodiment of this utility model, a first hole 6 is provided in the lower middle part of the mounting groove 2, and a second hole 7 is provided on the cover plate 5. After the cover plate 5 is placed on the electric groove 4 and the manual groove 3, it is fixed by the first screw in conjunction with the first hole 6 and the second hole 7.

[0032] In a specific embodiment of this utility model, two limiting posts 8 are provided in the mounting groove 2 on the side away from each other, which are used to limit the left and right sidewalls of the cover plate 5.

[0033] In a specific embodiment of this utility model, the two limiting posts 8 are respectively provided with limiting post holes 9 for installing another clutch housing 1.

[0034] The cover plate 5 is secured by screws through the first hole 6 and the second hole 7. Simultaneously, the left and right limiting posts 8 precisely limit the movement of the cover plate on both sides, preventing component misalignment during assembly. The assembly process is simplified from the traditional multi-body alignment + multiple sets of screws to cover plate closing + one set of screws tightening, improving assembly efficiency. The cover plate 5 provides longitudinal limiting for the manual / electric components, and the limiting posts 8 provide lateral limiting for the cover plate, forming a three-dimensional limiting structure to prevent component displacement or loosening during long-term use or vibration of the smart lock. The cover plate 5 is detachable; when internal components (such as gears or springs) malfunction, only one set of screws needs to be removed to open the cover for inspection, eliminating the need to disassemble the entire clutch housing and reducing after-sales maintenance costs.

[0035] Example 2: like Figures 1-8As shown, an intelligent lock clutch motor assembly, in a specific embodiment of this utility model, the electric drive component includes an electric motor 11 installed in the electric slot 4 and a drive gear 12 disposed at the output end of the electric motor 11. A central rotating shaft 13 is rotatably disposed on the cover plate 5 between the electric drive component and the manual drive component. A central gear 14 is disposed on the central rotating shaft 13. The central gear 14 and the drive gear 12 are connected by a driven gear 15. An arc-shaped push block 16 is pushed and pulled by a rotating lifting component on the central rotating shaft 13.

[0036] Efficient transmission of electric drive components: The electric motor 11 is driven by a three-stage meshing transmission through the driving gear 12 → driven gear 15 → center gear 14, which, together with the concentrated power output of the central shaft 13, ensures a stable transmission ratio and avoids power loss. Compared with traditional single gear transmission, it has a stronger load capacity and is suitable for the needs of high-torque smart locks.

[0037] In a specific embodiment of this utility model, the rotating lifting assembly includes a housing 17 connected at the top to an arc-shaped push block 16. A fixing plate 23 is provided inside the housing 17. One end of the central rotating shaft 13, away from the central gear 14, passes through the bottom of the housing 17 and the fixing plate 23 and extends to the top inside the housing 17. A strip hole 18 is provided on the side wall of the housing 17 and below the fixing plate 23. A horizontal fixing column 19 is provided on the central rotating shaft 13. A coiled spring 20 is wound on the central rotating shaft 13 and between the bottom inside the housing 17 and the fixing plate 23. The upper and lower ends of the coiled spring 20 extend into the strip hole 18, and the fixing column 19 extends horizontally through the coiled spring 20. When the central rotating shaft 13 rotates, it drives the fixing column 19 to push the coiled spring 20 up and down. A lifting groove 21 for the housing 17 to move up and down is provided between the manual groove 3 and the electric groove 4 and in the lower middle part of the mounting groove 2.

[0038] The design of the fixed column 19 of the central rotating shaft 13, the coiled spring 20, and the strip hole 18 transforms the rotational motion into the linear lifting motion of the housing 17, which pushes the arc-shaped push block 16 to move smoothly without jamming or offset, ensuring that the lock body push block accurately enters and exits the lock groove and improves the response accuracy of unlocking / locking. In a specific embodiment of this utility model, the clutch housing 1 is provided with housing strip holes 22 for the upper and lower ends of the coiling spring 20 to extend into, and the side wall of the housing 17 is provided with a notch 24 located below the fixing plate 23.

[0039] The structure of the housing strip-shaped hole 22 provides space for both ends of the coiled spring 20, allowing it to be fitted with the structure of the coiled spring 20 during installation. A notch 24 is provided on the side wall of the housing 17, such as... Figure 8 As shown, the notch 24 is L-shaped, which facilitates the installation of the central rotating shaft 13 and the coiled spring 20.

[0040] In a specific embodiment of this utility model, the manual drive assembly includes an outlet 31 at the top of the manual slot 3, a manual keyhole 32 at the bottom of the manual slot 3, a columnar rotating body 33 rotatably disposed in the manual slot 3, an insertion hole 34 at the upper end of the rotating body 33, and a driven post 35 rotatably inserted into the insertion hole 34. The lower end of the rotating body 33 is provided with a keyhole for inserting a manual key. The wall of the insertion hole 34 is provided with several arc-shaped guide grooves 36. Several guide blocks 37 extend from the side wall of the driven post 35 and extend into the corresponding arc-shaped guide grooves 36. A plurality of sliding guide blocks 41 are provided on the side wall of the driven column 35, and sliding guide holes 42 are correspondingly provided on the manual groove 3 and / or the cover plate 5. As the rotating body 33 rotates in the forward and reverse directions, the sliding guide blocks 41 slide along the sliding guide holes 42 through the arc-shaped guide groove 36 and the guide block 37, thereby driving the driven column 35 to rise and fall. A spring 38 is provided between the upper end of the driven column 35 and the bottom of the arc-shaped push block 16 and located at the outlet 31. A limit block 44 is provided on the lower side wall of the rotating body 33, and a limit groove 43 is provided on the cover plate 5 for the limit block 44 to slide in it.

[0041] The manual drive component is labor-saving and precise: the arc-shaped guide groove 36 of the rotating body 33 cooperates with the guide block 37 of the driven column 35. Through the mechanical conversion of rotation → guidance → lifting, the user can drive the driven column 35 to rise and fall smoothly by turning the manual key without the need for additional force; the guiding effect of the sliding guide block 41 and the sliding guide hole 42 prevents the driven column from tilting when rising and falling, and the manual operation feels smooth.

[0042] In a specific embodiment of this utility model, a fixed platform 39 with an inverted T-shaped cross-section is fixed to the upper end of the driven column 35. An annular groove 40 is provided on the upper surface of the fixed platform 39, and the spring 38 is partially inserted into the annular groove 40. The structure of the annular groove 40 and the fixed platform 39 further facilitates the installation of the spring 38, and since the spring 38 is partially in the annular groove 40, lateral leakage and displacement will not occur.

[0043] In a specific embodiment of this utility model, two arc-shaped guide grooves 36 are provided, and the two arc-shaped guide grooves 36 are symmetrically arranged on the upper hole wall of the insertion hole 34. The driven post 35 is provided with two symmetrical guide blocks 37, which are arranged in a vertical strip shape and are correspondingly arranged in the arc-shaped guide grooves 36.

[0044] The spring 38 at the upper end of the driven column 35 buffers the pressure of manual operation and avoids component deformation caused by rigid contact; the dual drive modes are independent and linked: the electric drive drives the arc-shaped push block 16 through the motor-gear set-rotating lifting assembly, and the manual drive pushes the arc-shaped push block 16 through the key-rotating main body-driven column-spring 38. Both share the arc-shaped push block 16 as the power output end, but the transmission paths are independent and do not interfere with each other. Seamless switching in emergency scenarios: When the intelligent control fails (such as when the battery is depleted or the circuit fails), the manual drive component can be directly applied. The buffering effect of spring 38 prevents the impact force from damaging the component during manual operation, ensuring the reliability of emergency unlocking and solving the pain point of traditional smart locks locking up when the electric motor fails. Manual operation limit protection: The limit block 44 of the rotating body 33 cooperates with the limit groove 43 of the cover plate 5 to limit the rotation angle of the rotating body 33, and at the same time limit the forward and backward movement of the rotating body 33. Figure 5 As can be seen, the limiting groove 43 is semi-circular and has an upward-extending section, which allows the rotating body 33 to be pushed upward a distance after rotation, making it easy to open manually.

[0045] like Figure 6 As shown, when the electric drive assembly is inactive, i.e., the arc-shaped pusher 16 is in the lower position and not pushed upwards, the coiled spring 20 inside the housing 17 is not under force and is in its normal position. If the electric motor 11 receives an electrical signal, the electric motor 11 drives the three-stage meshing transmission of the drive gear 12 → driven gear 15 → center gear 14, causing the central shaft 13 to rotate. When the central shaft 13 rotates, it drives the fixed column 19, causing the coiled spring 20 to be pushed upwards. Because the two ends of the coiled spring 20 are limited by the strip holes 18, the entire housing 17 and the arc-shaped pusher 16 rise. If... With the electric drive assembly in a non-operational state, insert the mechanical key to rotate the main body 33. The arc-shaped guide groove 36 of the main body 33 cooperates with the guide block 37 of the driven column 35. Through the mechanical conversion of rotation → guidance → lifting, the driven column 35 pushes upward, driving 38 to push the arc-shaped push block 16 upward. The arc-shaped push block 16 rises, driving the housing 17 to rise. At this time, the central rotating shaft 13 does not rotate, but because the housing 17 rises, the coiled spring 20 is compressed. As the mechanical key rotates and resets, under the reset force of the coiled spring 20, the housing 17 and the arc-shaped push block 16 fall and reset.
