Description

Technical Field

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

[0002] The clutch mechanism of a smart lock is a core mechanical and electronic control linkage component in a smart door lock. Its main function is to "connect" or "disconnect" between the electronic control system and the mechanical transmission system, thereby controlling whether the external handle can drive the bolt to move, so as to balance security, convenience and emergency opening capability.

[0003] Patent CN222253515U discloses a clutch transmission mechanism for a smart lock, belonging to the field of lock technology. It includes a lock body with a transmission mechanism inside. A latch is located on one side of the transmission mechanism, and a protective cover is connected to one side of the lock body. A cleaning component is located inside the protective cover, and a handle is connected to the side wall of the lock body below the protective cover. While this patent involves removing a wiping cotton pad from a storage box and then using it to clean the components of the transmission mechanism to prevent fingerprints from remaining on them and thus preventing unauthorized access to these fingerprints, for applications requiring higher security levels, this single electronic lock structure alone is insufficient to provide adequate anti-theft protection and cannot meet users' needs for high-security features such as multiple physical locking mechanisms.

[0004] Therefore, a smart lock clutch mechanism with dual locking modes is needed. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents, which cannot provide sufficient anti-theft protection by relying solely on such a single electronic lock structure for application scenarios requiring higher security levels, and cannot meet users' needs for high security functions such as multiple physical locks, this utility model provides an intelligent lock clutch mechanism with dual locking modes.

[0006] The technical implementation scheme of this utility model is as follows: an intelligent lock clutch mechanism, including a mounting shell, a rotating rod, a handle, a contact plate, a cylinder, a limit frame, a pin, a guide rod, a latch, a spring, an operation panel, a battery, and a controller. A rotating rod is rotatably mounted on the front center of the mounting shell. A handle is fixedly connected to the front end of the rotating rod, and a contact plate is fixedly connected to the rear end of the rotating rod. Two cylinders are symmetrically mounted on the front side inside the mounting shell. The extension rods of the two cylinders are connected to the limit frame. A pin is provided in the middle of the limit frame, and the pin can be inserted into or disengaged from a limit hole opened on the rotating rod. A guide rod is fixedly connected inside the mounting shell. A latch is slidably mounted on the end of the guide rod facing the door frame. The contact plate abuts against the latch, causing the latch to extend... In the out state, it can be inserted into the lock hole on the door frame. A spring is sleeved on the guide rod, and the two ends of the spring are connected to the lock tongue and the guide rod respectively. An operation panel is embedded in the upper front of the mounting housing. A battery is installed in the upper part of the mounting housing and is electrically connected to the operation panel. A controller is installed in the lower part of the mounting housing and is electrically connected to the operation panel and the cylinder. It also includes a motor, a bevel gear set, a ball screw assembly, and a limit plate. A motor is installed in the bottom of the mounting housing and is electrically connected to the controller. A ball screw assembly is rotatably installed inside the mounting housing. The output shaft of the motor and the end of the ball screw assembly are both equipped with a bevel gear set. A limit plate is installed on the left end of the ball screw assembly and is inserted into the corresponding lock hole in the door frame.

[0007] Optionally, it also includes a mounting plate, a camera, a memory card, and a Bluetooth module. The mounting plate is fixedly connected to the upper front of the mounting shell, multiple cameras are mounted on the mounting plate, a memory card is embedded in the rear of the mounting plate, and a Bluetooth module is located behind the camera.

[0008] Optionally, it also includes a connecting plate, a movable plate, and a cleaning cotton. The connecting plate is snapped onto the upper front side of the mounting housing, the movable plate is slidably mounted on the connecting plate, and the cleaning cotton is mounted on the rear side of the movable plate, with the cleaning cotton in contact with the operation panel.

[0010] Optionally, it also includes a damping ring, which is provided on the front side of the mounting housing and is in close contact with the connecting plate.

[0011] Optionally, it also includes sealing rings, with two sealing rings embedded in each of the two through holes on the left side of the mounting housing. The upper sealing ring surrounds the locking tongue, and the lower sealing ring surrounds the limiting plate.

[0012] Compared with the prior art, this utility model provides an intelligent lock clutch mechanism, which has the following beneficial effects: 1. By enabling the dual locking mode through the operation panel, the controller receives the command and drives the motor to run. The motor output shaft drives the ball screw assembly to rotate through the bevel gear set. The ball screw converts the rotational motion into linear motion, pushing the limit plate connected to it to extend towards the door frame and insert into the corresponding lock hole, forming a second physical lock, further enhancing the anti-theft capability and meeting the user's high security needs.

[0013] 2. The camera captures video images of the door in real time, and the acquired data can be stored in the built-in memory card. The Bluetooth module supports short-range wireless communication with the user's mobile device, which can be used to transmit captured images, receive unlocking commands after authentication, and synchronize system time, thereby realizing remote status query, wireless unlocking and security linkage functions, further enhancing security capabilities.

Detailed Implementation

[0022] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] Example 1: A smart lock clutch mechanism, please refer to... Figures 1-6 The system includes a mounting housing 1, a rotating rod 2, a handle 3, a contact plate 4, a cylinder 5, a limit bracket 6, a pin 601, a guide rod 7, a locking tongue 8, a spring 9, an operation panel 10, a battery 11, and a controller 17. A rotating rod 2 is rotatably mounted on the front center of the mounting housing 1. A handle 3 is fixedly connected to the front end of the rotating rod 2, and a contact plate 4 is fixedly connected to the rear end of the rotating rod 2. Two cylinders 5 are symmetrically mounted on the front inside the mounting housing 1. The extension rods of the two cylinders 5 are connected to the limit bracket 6. A pin 601 is located in the middle of the limit bracket 6. The rotating rod 2 can be inserted into or disengaged from the limiting hole. A guide rod 7 is fixedly connected inside the mounting housing 1. A latch 8 is slidably provided at the end of the guide rod 7 facing the door frame. The contact plate 4 abuts against the latch 8, so that the latch 8 can be inserted into the lock hole on the door frame when extended. A spring 9 is sleeved on the guide rod 7, and the two ends of the spring 9 are connected to the latch 8 and the guide rod 7 respectively. An operation panel 10 is embedded in the upper front part of the mounting housing 1. A battery 11 is installed in the upper part of the mounting housing 1 and is electrically connected to the operation panel 10. The lower part of the mounting housing 1 is equipped with... Equipped with a controller 17, which is a microcontroller based on an ARM Cortex-M4 core, the controller 17 is electrically connected to the operation panel 10 and the cylinder 5. It also includes a motor 12, a bevel gear set 13, a ball screw assembly 14, and a limit plate 15. The motor 12 is installed at the bottom inside the mounting housing 1 and is electrically connected to the controller 17. The ball screw assembly 14 is rotatably mounted inside the mounting housing 1. The output shaft of the motor 12 and the end of the ball screw assembly 14 share a bevel gear set 13. A limiting plate 15 is provided on the left end. The limiting plate 15 is inserted into the corresponding lock hole of the door frame. An anti-slip sleeve 301 is fitted on the handle 3 to increase the friction between the handle 3 and the hand, making the operation more comfortable and less prone to slipping. Two sealing rings 25 are embedded in the two through holes on the left side of the mounting shell 1. The upper sealing ring 25 surrounds the lock tongue 8, and the lower sealing ring 25 surrounds the limiting plate 15. This effectively prevents dust, moisture and other foreign objects from entering the interior of the mounting shell 1 from the gaps of these moving parts, protecting the internal precision mechanism and improving the durability and reliability of the lock.

[0024] When the door is closed, the latch 8 extends out of the mounting shell 1 under the force of the spring 9 and inserts into the corresponding lock hole on the door frame, achieving basic mechanical locking. When the user needs to open the door, they issue an unlocking command through the operation panel 10 (e.g., by entering a password or fingerprint). The user authenticates their identity through the operation panel 10. After successful authentication, the operation panel 10 sends an unlocking signal to the controller 17. The controller 17 receives the command through the receiver and activates two cylinders 5. The telescopic rods of the two cylinders 5 move synchronously, pushing the limit bracket 6 downward. The pin 601 disengages from the limit hole on the rotating rod 2. At this time, the rotating rod 2 is unlocked and can rotate freely. The user turns the handle 3, causing the rotating rod 2 to rotate. The contact plate 4 at the rear end of the rotating rod 2 rotates accordingly and no longer blocks the latch 8. The spring 9 rebounds, causing the latch 8 to slide along the guide rod 7 into the housing, disengaging from the lock hole on the door frame, thus opening the door. After releasing the handle 3, the user manually turns the handle 3 back to its original position, and the contact plate 4... 4. The cylinder rotates and pushes the latch 8 to slide along the guide rod 7 towards the door frame. The latch 8 is inserted into the lock hole of the door frame. At the same time, the cylinder 5 retracts its telescopic rod, causing the limit bracket 6 to move upward. The pin 601 is re-inserted into the limit hole of the rotating rod 2, locking the rotating rod 2 again to prevent the handle 3 from being forcibly turned to open the door from the outside, thus improving the anti-pry performance. In high-security scenarios (such as nighttime arming), the user can enable the dual locking mode through the operation panel 10. After receiving the instruction, the controller 17 drives the motor 12 to run. The output shaft of the motor 12 drives the ball screw assembly 14 to rotate through the bevel gear set 13. The ball screw converts the rotational motion into linear motion, pushing the limit plate 15 connected to it to extend towards the door frame and insert into the corresponding lock hole, forming a second physical lock, further enhancing the anti-theft capability, thereby meeting the user's high security requirements. When the unlocking operation is performed, the controller 17 simultaneously controls the motor 12 to reverse, causing the limit plate 15 to retract into the mounting housing 1.

[0025] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 5 It also includes a mounting plate 18, cameras 181, a memory card 19 and a Bluetooth module 20. The mounting plate 18 is fixedly connected to the upper front side of the mounting shell 1. Three cameras 181 are mounted on the mounting plate 18. The memory card 19 is embedded in the rear side of the mounting plate 18. The Bluetooth module 20 is located behind the cameras 181.

[0026] When in use, the camera 181 captures video images of the door in real time. The acquired data can be stored in the built-in memory card 19 for easy review and evidence collection later. The Bluetooth module 20 supports short-range wireless communication with the user's mobile device and can be used to transmit captured images, receive unlocking commands after authentication, and synchronize system time, thereby realizing remote status query and security linkage functions, further enhancing security capabilities.

[0027] Please see Figure 1 and Figure 6 It also includes a connecting plate 21, a movable plate 22, and a cleaning cotton 23. The connecting plate 21 is snapped onto the upper front side of the mounting shell 1. The movable plate 22 is slidably mounted on the connecting plate 21. The cleaning cotton 23 is mounted on the rear side of the movable plate 22 and contacts the operation panel 10. A damping ring 24 is mounted on the front side of the mounting shell 1. The damping ring 24 is in close contact with the connecting plate 21, which increases the frictional resistance between the connecting plate 21 and the mounting shell 1 and prevents the connecting plate 21 from accidentally loosening or falling off.

[0028] When the control panel 10 needs to be cleaned, the cleaning cotton 23 is moved by manually sliding the movable plate 22 to wipe the surface of the control panel 10, remove fingerprints and dust, so as to maintain the display clarity of the control panel 10 and ensure its normal operation.

[0029] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
