Description

Technical Field

[0001] The present invention relates to the technical field of smart locks, and in particular to a fully open smart lock clutch assembly. Background Art

[0002] Smart locks differ from traditional mechanical locks by offering more intelligent features in terms of user identification, security, and manageability. They are the locking components of access control systems. Smart locks are developing rapidly and becoming increasingly sophisticated. With the addition of fingerprint, password, voice, and remote control features, the lock bodies of smart locks have been redesigned, resulting in significantly higher prices. Traditional mechanical locks, on the other hand, face even more challenges when they are being retrofitted with smart locks. Generally, the entire lock structure must be replaced during the retrofit, especially when replacing the lock body, which can damage the door. This makes installation cumbersome and often requires replacing both the door and the lock, making it impractical. The lock can only be replaced, and upgrading the traditional mechanical lock is costly. Once a smart lock fails, repairing it is difficult, both replacing parts and replacing the smart lock is time-consuming and labor-intensive, impacting user experience. One important reason for this is the lock's internal structure. Both traditional mechanical locks and smart locks use an open key transmission mechanism. That is, once a key is inserted into the keyhole, it can rotate forward and reverse more than 360 degrees to control the movement of more than one bolt. However, the clutch mechanism of smart locks uses a multi-step unlocking mechanism, so key unlocking and smart unlocking are essentially two relatively independent structures. The clutch mechanism can only achieve a semi-open movement of less than 360 degrees to accommodate the new unlocking actuator. Therefore, it is difficult to retrofit smart locks with traditional locks, requiring the entire lock structure to be replaced. Summary of the Invention

[0003] The purpose of the present invention is to provide a fully open intelligent lock clutch assembly to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, a fully open smart lock clutch assembly is provided, which is characterized in that it includes a fully open clutch, which includes a swingable clutch ring, a clutch linkage, and a clutch shaft. The clutch linkage is linked to the clutch shaft, and the clutch ring is provided with a control magnet with opposite magnetic poles, and the clutch linkage is provided with a controlled magnet with the same magnetic pole. As the clutch ring swings, the control magnet and the controlled magnet interact with each other to form an alternating attraction and repulsion. The clutch shaft and the clutch linkage form an axial reciprocating motion linkage consistent with the direction of the magnetic pole.

[0005] This setting adopts a coaxial magnetic clutch structure to allow the clutch shaft to move in the axial direction. When upgrading a traditional mechanical lock, you only need to link the clutch shaft with the lock core of the traditional mechanical lock to complete the synchronous rotation with the mechanical lock core. It can complete a fully open rotation of more than 360 degrees. Without changing the structure of the traditional mechanical lock, the traditional mechanical lock can be converted into a smart lock without disassembling the lock body. This installation and modification method does not even require professionals, and users can modify it themselves, which greatly reduces the difficulty of modification and upgrading installation, and also greatly reduces the modification cost of smart locks. It is highly applicable and can modify any traditional lock.

[0006] Preferably, it also includes a motor, a swing gear is provided on the periphery of the clutch ring, the output wheel of the motor is meshed with the swing gear to form a reciprocating swing structure, two groups of control magnets are provided on the clutch ring, and the two groups of control magnets have opposite magnetic poles. The clutch linkage is annular, and two symmetrical controlled magnets are provided on the clutch linkage, and the positions of the controlled magnets and the control magnets correspond to each other. The clutch linkage is coaxially sleeved on the clutch shaft to form a coaxial fixed connection.

[0007] When modifying and upgrading traditional mechanical locks, this setting only requires integrating smart modules such as fingerprints, passwords, and remote controls into a smart panel, fixing it on the door in any way, and electrically connecting the smart module to the motor to complete axial clutch control. When upgrading traditional mechanical locks, there is no need to move the original lock body at all. You only need to align the clutch shaft with the traditional lock core to complete the clutch coordination. Under the premise of retaining the traditional mechanical lock structure, the traditional mechanical lock can be upgraded to a smart lock, which greatly reduces the modification cost and installation difficulty. By using the principle that like magnets repel each other and opposite magnets attract each other, the initial position of the clutch ring is used to control the magnet and the magnet to be in a state of opposite attraction, and the clutch shaft and the lock core are in a state of opposite attraction. In the disengaged state, when the clutch ring swings, the other set of control magnets and the controlled magnets form a like-charge repulsive state, pushing the clutch shaft axially out, allowing the clutch shaft and the external lock core to form a closed state, forming a circumferentially fully open rotation state. Then the actuator of the smart lock can completely simulate the action of the key, and can directly unlock, lock and other complex operations, while the existing smart locks must design a completely new structure to complete. Through the structure of the present invention, traditional mechanical locks can be directly upgraded to high-end smart locks, and have functions and performance that most smart locks do not have, greatly reducing the cost of smart locks, and all traditional locks can be upgraded without replacing the existing lock body structure.

[0008] Preferably, it also includes a lock core, an adjustment tube, and an adjustment rod. A clutch groove is provided at one end of the adjustment rod, and a clutch block is provided at the head of the clutch shaft. The clutch block is adapted to the clutch groove. The clutch block and the clutch groove reciprocate axially with the clutch shaft to form a plug-in and disengage clutch fit. The lock core is sleeved with the adjustment tube, and the adjustment tube and the adjustment rod are plugged in to form a sliding adjustment structure. The adjustment tube, the adjustment rod, and the clutch shaft are coaxially arranged.

[0009] This setting uses an adjustable lock core structure. When upgrading traditional mechanical locks, there is also a very important issue. Due to the many types and sizes of traditional mechanical locks, the thickness of the door will vary. When installing smart locks, you need to match smart locks of different sizes. After adopting the adjustable lock core structure, when upgrading traditional mechanical locks, you can have a wider thickness adjustment. As long as you use the structure of the adjusting rod and adjusting tube, you can make a lock core adapt to the thickness of most doors. The adjusting rod and adjusting tube are adjusted to the thickness of the corresponding door, and the lock core is fixed in the position of the original lock core, which can perfectly adapt to the structure of the traditional mechanical lock. Without moving the lock body, the full-lock type and full-size traditional lock upgrade can be achieved. A clutch groove is set on the adjusting rod, and a clutch structure is formed with the clutch block on the head of the clutch shaft. The fully open movement is directly given to the lock core, which greatly simplifies the linkage structure of the smart lock, making the upgrade of traditional locks simpler and the performance of the lock more improved.

[0010] Preferably, a mechanical lock core is also included, and a telescopic rod is provided at the end of the mechanical lock core. The telescopic rod telescopes as the mechanical lock core rotates. The telescopic rod is coaxial with the clutch shaft. When the telescopic rod is extended, it can support the clutch shaft and push the clutch shaft forward.

[0011] This setting uses a retractable mechanical lock core, which cooperates with a fully open clutch structure. In the event of a failure in the clutch structure or a failure in the smart lock or there is no power, various operations are completed by directly rotating the mechanical lock core to control the telescopic rod to push the movement of the clutch shaft. Because it is a magnetic clutch structure, when the telescopic rod retracts, the clutch ring will suck the clutch linkage back, and the clutch structure directly replaces the reset mechanism, further simplifying the structure of the lock. Since they are all coaxial settings, the structure of the lock is more optimized and the volume is reduced under the premise of structural simplification. This setting does not describe the specific structure of the mechanical lock core and the telescopic rod in detail because this mechanical lock core with a telescopic rod is existing technology and the mechanical lock core can be purchased online.

[0012] Preferably, it also includes a rotating handle, which is provided with an annular fixing groove, and a protective cover is embedded in the annular fixing groove. The mechanical lock core is embedded in the rotating handle, and the lock hole of the mechanical lock core is exposed in the annular fixing groove. A inferior arc cavity is provided at the edge of the annular fixing groove, and the inferior arc cavity is lower than the annular fixing groove.

[0013] This setting uses a rotary handle. The movement of the rotary handle matches the characteristics of the open clutch structure, which facilitates circumferential rotation operations of more than 360 degrees. A minor arc cavity is provided at the edge of the annular fixed groove. No tools are required when opening the protective cover. Just press down on the position of the minor arc cavity corresponding to the protective cover to make the protective cover tilt up and open. When covering the protective cover, just align it with the center and press inward to complete the inlay. It not only has good sealing and can protect the mechanical lock core, but is also easy to use.

[0014] Preferably, it also includes an intelligent panel and a fixing seat, the fixing seat includes a convex ring and a cover plate, the intelligent panel is fixed on the fixing seat, the rotary handle is rotatably set on the fixing seat, the clutch ring is sleeved on the convex ring, and the cover plate is covered on the convex ring to form a clutch ring fixing structure, two guide holes are provided on the cover plate, and two guide columns are provided on the clutch linkage, the guide columns are sleeved in the guide holes to form a stable coaxial guide structure, and the magnets are embedded in the guide columns.

[0015] This setting uses a fixing base to integrate the smart panel and fix the related supporting structures. Therefore, when upgrading the traditional mechanical lock, only a screwdriver is needed to fix the smart panel and the fixing base on the corresponding door, and then the installation can be completed. There is no need for complicated disassembly and installation steps. Users can upgrade by themselves. The convex ring can help the clutch ring to have better coaxiality in swinging, and the guide structure also ensures the coaxiality of the clutch structure movement, making the performance more stable.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The fully open smart lock clutch assembly can directly transform and upgrade the traditional mechanical lock and directly become a high-end smart lock terminal. Without changing the lock body, all sizes and models of transmission mechanical locks can be transformed into smart locks. One set of structures is suitable for all mechanical locks, which is highly applicable. It also simplifies the structure of the smart lock, reduces the production, installation, and maintenance costs of the smart lock, and increases the upper limit of intelligent control, so that the transformed smart lock and the integrated new smart lock have the same or even more intelligent operation space, so that poor and backward areas can also easily popularize smart locks, which is of extraordinary significance to the popularization of smart lock terminals, especially when a fault occurs, it only takes a short time to replace an assembly. Compared with smart locks, maintenance is more convenient and quick. If a smart lock fails, it is impossible to directly replace the smart lock before the fault is found, which brings great inconvenience to users. BRIEF DESCRIPTION OF THE DRAWINGS
