[0001] This utility model relates to the field of lock structure technology, and in particular to an intelligent ball lock. Background Technology

[0002] With increasing demands for security and convenience, smart ball locks have gradually become a hot topic in the market. Most existing smart ball locks use motor-driven unlocking, which is not only complex in structure and expensive to manufacture, but also consumes a lot of power and generates significant noise during use. When the front lock is forcibly turned, the internal drive components or unlocking / locking mechanism of the ball lock can easily fail or be damaged, resulting in weak resistance to forced entry and compromising the security of the ball lock. Utility Model Content

[0003] This utility model provides an intelligent ball lock that helps reduce power consumption and noise, avoids damage to the internal structure of the intelligent ball lock from forced entry, and improves the security of the intelligent ball lock.

[0004] This utility model embodiment provides an intelligent ball lock, which includes a first handle assembly and a clutch assembly. The first handle assembly is disposed on the outside of the door panel. The clutch assembly is rotatably connected to the first handle assembly. The clutch assembly includes an electromagnetic drive part, a locking member, and a first limiting member. The first limiting member is connected to the first handle assembly and has a first groove for the locking member to extend into. The spindle of the electromagnetic drive part has a first position in an energized state and a second position in an de-energized state. In the first position, the spindle extends out and abuts against one end of the locking member to restrict the movement of the locking member radially along the first limiting member. The other end of the locking member is located in the first groove, so that the first limiting member and the first handle assembly rotate synchronously.

[0034] This utility model provides an intelligent ball lock that helps reduce power consumption and noise, avoids damage to the internal structure of the intelligent ball lock from forced entry, and improves the security of the intelligent ball lock.

[0035] like Figures 1 to 3 As shown, this embodiment of the utility model provides an intelligent ball lock, which includes a first handle assembly 100 and a clutch assembly 200. The first handle assembly 100 is disposed on the outside of the door panel 600. The clutch assembly 200 is rotatably connected to the first handle assembly 100, and the clutch assembly 200 includes an electromagnetic drive part 210, a locking member 220, and a first limiting member 230, which is circumferentially connected to the first handle assembly 100. Figures 4 to 5As shown, the first limiting member 230 is provided with a first groove 231 into which the locking member 220 extends. Preferably, the electromagnetic drive part 210 is a solenoid. The spindle 211 of the solenoid has a first position in the energized state and a second position in the de-energized state. In the first position, the spindle 211 extends out and abuts against one end of the locking member 220 to restrict the movement of the locking member 220 radially along the first limiting member 230. The other end of the locking member 220 is located in the first groove 231, so that the first limiting member 230 and the first handle assembly 100 rotate synchronously. In the second position, the spindle 211 retracts and separates from one end of the locking member 220 to unlock the movement of the locking member 220 radially along the first limiting member 230. The other end can leave the first groove 231, and free rotation is formed between the first handle assembly 100 and the first limiting member 230.

[0036] This utility model provides a clutch assembly 200 in the intelligent ball lock structure. The clutch assembly 200 includes an electromagnetic drive unit 210, a locking member 220, and a first limiting member 230. By energizing and de-energizing the electromagnetic drive unit 210, the spindle 211 has an extended first position and a retracted second position to lock or unlock the locking member 220. This further enables the first handle assembly 100 and the clutch assembly 200 to form a linkage or free-running state. By setting the electromagnetic drive unit 210 as the drive structure, the structure is simple, which helps to reduce manufacturing costs and also reduces power consumption and noise. In the first position, the spindle 211 extends and abuts against one end of the locking member 220 to restrict the movement of the locking member 220 radially along the first limiting member 230. The other end of the locking member 220 is located in the first groove 231, so that the first limiting member 230 and the first handle assembly 100 rotate synchronously. In the second position, the spindle 211 retracts and separates from one end of the locking member 220 to unlock the movement of the locking member 220 radially along the first limiting member 230. The other end can leave the first groove 231, and free rotation is formed between the first handle assembly 100 and the first limiting member 230, avoiding the problem of damage to the internal structure of the smart ball lock by forceful opening, and improving the security of the smart ball lock.

[0037] like Figure 3 As shown, the clutch assembly 200 further includes a clutch sleeve 240 and a rotating shaft 250. The clutch sleeve 240 is rotatably connected to the first handle assembly 100, and the electromagnetic drive unit 210 is disposed within the clutch sleeve 240. The rotating shaft 250 is connected to the clutch sleeve 240, and the clutch sleeve 240 can drive the rotating shaft 250 to move. The rotating shaft 250 is rotatably mounted within the first limiting member 230. One end of the rotating shaft 250 is fixedly connected to the clutch sleeve 240 by a screw, and the other end is fixedly connected to the connecting shaft 280 by a cotter pin. Both the clutch sleeve 240 and the connecting shaft 280 can rotate together with the rotating shaft 250. Figures 4 to 5As shown, the rotating shaft 250 has a through hole 251 in the radial direction. The first groove 231 is correspondingly connected to the through hole 251. The locking member 220 is flexibly disposed in the through hole 251 and can move up and down in the through hole 251 under the combined action of the first limiting member 230 and the second elastic member. In the first position, the spindle 211 can extend into the through hole 251.

[0038] like Figure 3 As shown, the clutch assembly 200 further includes a first elastic element 260 and a second elastic element 270. The first elastic element 260 is connected to the first limiting member 230 and provides an elastic restoring force for the movement of the first limiting member 230. The second elastic element 270 is disposed outside the locking member 220 and provides an elastic restoring force for the movement of the locking member 220. Preferably, the first elastic element 260 is a torsion spring and the second elastic element 270 is a spring.

[0039] like Figure 4 As shown, the locking member 220 includes a first part and a second part that are connected to each other. The first part can extend into or leave the first groove 231 under the elastic force of the second elastic member 270. The first part has a spherical guide structure 221, and the electromagnetic drive part 210 abuts against the second part.

[0040] Specifically, when the first limiting member 230 rotates circumferentially, the first groove 231 of the first limiting member 230 will exert a force on the locking member 220, forcing the locking member 220 to move downward and forcing the locking member 220 to rotate with the first limiting member 230. When the locking member 220 can move downward and is able to move downward until the spherical guide structure 221 of the locking member 220 is completely separated from the area of ​​the first groove 231 of the first limiting member 230, the first limiting member 230 will not be able to drive the locking member 220 to rotate. When the downward movement of the locking member 220 is blocked and cannot be separated from the area of ​​the first groove 231 of the first limiting member 230, the locking member 220 will rotate with the first limiting member 230. In addition, the first limiting member 230 is also connected to the first elastic member 260. Without the action of external force, the first elastic member 260 can always return the first limiting member 230 to the initial position, and in the initial position, the spherical guide structure 221 of the locking member 220 can always abut against the first groove 231 of the first limiting member 230.

[0041] like Figure 3As shown, the clutch assembly 200 also includes a connecting shaft 280, which is connected to a rotating shaft 250. The rotating shaft 250 can drive the connecting shaft 280 to rotate. The connecting shaft 280 is connected to the lock body 500. When the connecting shaft 280 rotates to a preset angle, it can unlock the lock body 500, at which point actions such as opening the door can be realized. Preferably, the connecting shaft 250 is a square connecting shaft. The specific implementation of the lock body 500 is not limited in this application. The smart ball lock also includes a second handle assembly 300, which is disposed inside the door panel 600 and connected to the connecting shaft 280. The rotation of the connecting shaft 280 drives the second handle assembly 300 to rotate.

[0042] like Figures 7 to 8 As shown, the first handle assembly 100 includes a first grip portion 110 and an emergency unlocking assembly 120. The first grip portion 110 is a gripping component installed on the outside of the door panel 600 for the user to rotate and unlock the door lock. The first grip portion 110 transmits the rotational force applied by the user to the clutch assembly 200. The first grip portion 110 has a cavity and includes a first connecting portion 111, which is connected to the clutch bushing 240, as shown... Figure 2 As shown, specifically, the first connecting part 111 has a cylindrical structure. The outer periphery of the first connecting part 111 is provided with several limiting grooves 1111 for engaging with the clutch assembly 200 and transmitting rotational load. In this application, two limiting grooves 1111 are oppositely provided on the outer periphery of the first connecting part 111. The outer periphery of the first connecting part 111 is also provided with an annular groove 1112 for engaging the retaining ring 290, thereby axially fixing the first gripping part 110 to the clutch assembly 200. A wire hole 112 is also provided on the rear end face of the first gripping part 110 for the wire to pass through.

[0043] like Figures 7 to 8 As shown, the emergency unlocking component 120 is disposed within the cavity and is connected to the clutch bushing 240, enabling the clutch bushing 240 to rotate. The emergency unlocking component 120 includes an emergency lock cylinder 121, a lock cylinder sleeve 122, a baffle 123, etc. The emergency unlocking component 120 is fixedly installed in the cavity inside the first grip portion 110, and the lock cylinder housing is fixedly connected to the first grip portion 110 through the lock cylinder sleeve 122. The other end of the emergency lock cylinder 121 is provided with an emergency unlocking connecting shaft 113, which is connected to the clutch bushing 240 of the clutch assembly 200. The emergency unlocking connecting shaft 113 and the clutch bushing 240 are mutually constrained circumferentially, meaning that if one rotates, the other will also rotate, which helps to prevent damage to the emergency unlocking component 120 when the first handle assembly 100 is spinning freely.

[0044] like Figures 7 to 8As shown, the first handle assembly 100 further includes an identification module 130. The identification module 130 is flexibly rotatably disposed on the first grip portion 110 and can rotate eccentrically around the first grip portion 110, thereby exposing the emergency unlocking assembly 120. The identification module 130 is electrically connected to the electromagnetic drive portion 210 to perform an emergency unlocking operation. The identification module 130 is electrically connected to the chip inside the clutch assembly 200 via wires for power reception and communication. The identification module 130 can be used to collect identity information and verify identity information through the chip. It is understood that the identification module 130 can be one or more combinations of identity recognition methods such as digital password, fingerprint, card swiping, and palm vein recognition, and this application does not impose any limitations.

[0045] In this embodiment of the invention, the identification module 130 can identify the unlocking identity and issue an authorization signal to the emergency unlocking component 120. When the emergency unlocking component 120 is authorized, rotating the first gripping part 110 can drive the emergency unlocking component 120 to rotate, and the first connecting part 111 drives the clutch bushing 240 to rotate. Specifically, when the emergency lock cylinder 121 is not authorized, rotating the first gripping part 110 drives the lock cylinder housing to rotate, and the emergency unlocking connecting shaft 113 does not rotate; when the emergency lock cylinder 121 is authorized, rotating the first gripping part 110 drives the lock cylinder housing to rotate, and the connecting shaft 280 follows the rotation of the lock cylinder housing, thereby driving the clutch bushing 240 of the clutch component 200 to rotate. In the event of a failure of the electromagnetic drive unit 210 or the power supply component, the user can unlock the lock using the emergency unlocking component 120 inside the first gripping part 110. The emergency unlocking component 120 is connected to the clutch bushing 240, and the clutch component 200 is manually driven to rotate by rotating the first gripping part 110 to unlock the lock body 500.

[0046] like Figures 7 to 8As shown, the second handle assembly 300 includes a second grip portion 310, a power supply assembly 320, and a cover 330. The second grip portion 310 is a gripping component installed inside the door panel 600 for the user to rotate and unlock the door lock. The second grip portion 310 transmits the rotational force applied by the user to the clutch assembly 200. The second grip portion 310 has a cavity and includes a second connecting portion. The second connecting portion has a cylindrical structure with a square through hole in the center for the connecting shaft 280 to pass through. The outer periphery of the second connecting portion has several limiting grooves for cooperating with the second limiting member 410 of the rear cover assembly 400 to perform rotational load transmission. In this application, two limiting grooves are provided opposite each other on the outer periphery of the second connecting portion. The outer periphery of the second connecting portion also has an annular groove for locking a retaining ring, thereby axially fixing the second grip portion 310 to the rear cover assembly 400. The rear end face of the second grip portion 310 also has a wire hole for the wire to pass through. The power supply assembly 320 is disposed within the cavity. The power supply assembly 320 includes a battery 321 and a battery compartment 322. The battery compartment 322 is electrically connected to the chip of the clutch assembly 200 via wires and can supply power to the chip and other electronic components electrically connected to it. The cover 330 is detachably mounted on the second grip portion 310 by screws. The user can remove the cover 330 using tools to replace the battery 321 inside the battery compartment 322.

[0047] like Figure 2 As shown, the smart ball lock also includes: a back cover assembly 400, which is disposed inside the door panel 600 and connected to the clutch assembly 200. Figures 7 to 8 As shown, the rear cover assembly 400 includes a second limiting member 410 and a third elastic member 420. The second limiting member 410 is engaged with the second connecting portion. The third elastic member 420 is connected to the second limiting member 410 and provides elastic restoring force after the second grip portion 310 is twisted, realizing the reset function of the second grip portion 310. After the user rotates the second grip portion 310, the third elastic member 420 provides a reverse torque, causing the second grip portion 310 to return to its initial position, ensuring operational stability. The second handle assembly 300 is rotatably mounted on the rear cover assembly 400, and the connecting shaft 280 of the clutch assembly 200 passes through the rear cover assembly 400 and is inserted into the second handle assembly 300, so that when the clutch assembly 200 rotates, it can drive the second handle assembly 300 to rotate, realizing unlocking. The rear cover assembly 400 and the clutch assembly 200 are connected by two long studs, which can clamp the first handle assembly 100 and the second handle assembly 300 on the inner and outer sides of the door panel 600 respectively.

[0048] The specific working steps of the smart ball lock will be described below.

[0049] The user inputs the correct password or fingerprint through the identification module 130. The battery 321 supplies power to the electromagnetic drive unit 210, and the spindle 211 of the electromagnetic drive unit 210 extends out. The side wall of the spindle 211 abuts against the lower part of the locking member 220, restricting the downward movement of the locking member 220. At this time, rotating the first grip part 110 will drive the first limiting member 230 to rotate. Since the locking member 220 cannot move downward under the abutment of the spindle 211 of the electromagnetic drive unit 210, the first limiting member 230 will drive the locking member 220, the rotating shaft 250, and the connecting shaft 280 to rotate together, thereby opening the door lock body 500.

[0050] The chip is pre-set with a power-off timer. The chip will automatically disconnect the power supply to the electromagnetic drive unit 210, and the spindle 211 of the electromagnetic drive unit 210 will automatically retract. At this time, rotating the first gripping part 110 will cause the first limiting member 230 to rotate. Under the action of the first limiting member 230, the locking member 220 will overcome the elastic force of the second elastic member 270 and move downwards. The locking member 220 will leave the first groove 231. The first gripping part 110 cannot form a torque transmission path with the rotating shaft 250, and the torsional force cannot be transmitted to the rotating shaft 250, thus preventing the rotating shaft 250 and the connecting shaft 280 from rotating. Therefore, the door lock cannot be opened. At this time, the first gripping part 110 can only rotate freely, which helps to avoid damage to the internal structure of the smart lock due to forced opening, thereby improving the security of the smart lock.

[0051] This utility model's technical solution replaces the traditional motor with an electromagnetic drive unit 210 as the drive structure, reducing power consumption and noise, improving response speed, and simplifying the structure. This reduces manufacturing costs and further lowers power consumption and noise while increasing response rate. The clutch assembly 200 has a simple and compact structure, is easy to manufacture, and helps avoid damage to the internal structure of the smart ball lock from forced entry, thus improving the security of the smart ball lock.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
