Description

Technical Field

[0001] This utility model relates to an intelligent door lock, and more particularly to an electronic spherical lock. Background Technology

[0002] Existing smart electronic door locks consist of a front ball mounted on the outside, a rear ball mounted on the back, and a latch mechanism mounted on the inside. When starting from the outside, turning the front ball engages the latch mechanism via a clutch mechanism to unlock. Similarly, when starting from the inside, turning the rear ball engages the latch mechanism via a clutch mechanism to unlock. This structure, including both the front and rear balls, is relatively complex and inefficient to manufacture. Furthermore, the distance between the front and rear balls in existing smart door locks is relatively fixed, requiring different distances for different door thicknesses, resulting in poor versatility. Thirdly, when using the rear ball for deadbolt locking, existing smart door locks also employ electronic control, requiring the installation of electronic components and wiring on the rear ball, making installation cumbersome and inconvenient. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a locking mechanism for an electronic spherical lock.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An electronic spherical lock's locking mechanism includes a rear ball and a front ball. The front ball houses an unlocking motor for unlocking the clutch mechanism. An unlocking knob is mounted on the end face of the rear ball. A rotating rod, fixedly connected to the unlocking knob, is mounted inside the rear ball. A rotary pushing mechanism, reset by a return spring, is mounted at the end of the rotating rod. An electronic control board, electrically connected to the unlocking motor, is mounted inside the front ball. A micro switch is mounted on the electronic control board corresponding to the rotary pushing mechanism, and the end face of the rotary pushing mechanism abuts against the micro switch.

[0006] A mounting base is provided on the front ball, and a through channel is provided in the mounting base to connect the interior of the front ball to the outside. The rotating pushing mechanism is installed in the through channel.

[0007] The through channel consists of a rotating cavity and a mounting cavity. A limiting component is installed in the mounting cavity. The rotating pushing mechanism includes a sliding component that is reset by the reset spring and a rotating component that is fixedly connected to the rotating rod. The rotating component is rotatably installed in the rotating cavity, and the sliding component is slidably installed in the limiting component. The sliding component is provided with an extension rod that extends out of the limiting component, and the end face of the extension rod abuts against the micro switch.

[0008] The rotating component has a V-groove at one end near the sliding component, and the sliding component has a V-shaped protrusion corresponding to the V-groove, with the V-shaped protrusion being fitted into the V-groove.

[0009] The reset spring is installed between the limiting member and the sliding member.

[0010] The limiting member is provided with a sliding groove, and the sliding member is provided with a slider part corresponding to the sliding groove, and the slider part is slidably installed in the sliding groove.

[0011] The return spring is fitted onto the protruding rod.

[0012] The beneficial effects of this utility model are:

[0013] This invention features an unlocking motor for unlocking the clutch mechanism inside the front ball, an unlocking knob on the end face of the rear ball, a rotating rod fixedly connected to the unlocking knob inside the rear ball, and a rotary push mechanism reset by a return spring at the end of the rotating rod. An electronic control board electrically connected to the unlocking motor is installed inside the front ball, with a micro switch on the control board corresponding to the rotary push mechanism. The end face of the rotary push mechanism abuts against the micro switch. When the door is locked from the rear, turning the unlocking knob closes the micro switch via the rotary push mechanism, thereby controlling the locking between the unlocking motor and the clutch mechanism. This allows the front and rear balls to use the same clutch mechanism, eliminating the need for electronic components for unlocking on the rear ball. This significantly simplifies the structure of the ball lock, eliminates the hassle of wiring, effectively improves production efficiency, reduces installation failure rates, and lowers installation costs for users.

[0014] Depending on the door thickness, you only need to select a rotating rod of different lengths, which is highly versatile and easy to install on site. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0025] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0026] Reference Figures 1 to 7 An electronic spherical lock's deadbolt mechanism includes a rear ball 1 and a front ball 2. The front ball 2 houses an unlocking motor 19 for unlocking the clutch mechanism. An unlocking knob 3 is mounted on the end face of the rear ball 1. A rotating rod 4, fixedly connected to the unlocking knob 3, is installed inside the rear ball 1. A rotary push mechanism 5, reset by a return spring, is mounted at the end of the rotating rod 4. An electronic control board 17, electrically connected to the unlocking motor 19, is installed inside the front ball 2. A micro switch 18 is mounted on the electronic control board 17 corresponding to the rotary push mechanism 5. The end face of the rotary push mechanism 5 abuts against the micro switch 18. When the door is deadbolted, the unlocking knob 3 is turned, and the rotary push mechanism 5 is reset. The actuator 5 closes the micro switch 18, thereby controlling the unlocking motor 19 to lock with the clutch structure, preventing transmission between the front ball 2 and the bolt. When unlocking from behind the door, the unlocking knob 3 is turned in the opposite direction, and the rotating actuator 5 disconnects the micro switch 18, thereby controlling the unlocking motor 19 to unlock with the clutch structure, allowing transmission between the front ball 2 and the bolt. This achieves the use of the same clutch structure for both the front and rear balls, eliminating the need for electronic components for unlocking on the rear ball. This not only greatly simplifies the structure of the ball lock but also eliminates the hassle of threading wiring, effectively improving production efficiency while reducing installation failure rates and lowering installation costs for users.

[0027] Depending on the door thickness, you only need to select a rotating rod of different lengths, which is highly versatile and easy to install on site.

[0028] A mounting base 6 is provided on the front ball 2, and a through channel is provided in the mounting base 6 to connect the interior of the front ball 2 to the outside. The rotating pushing mechanism 5 is installed in the through channel.

[0029] The front ball 2 includes a housing, which comprises a body and a cover. The mounting base 6 is disposed on the body of the housing. The through channel consists of a rotating cavity 8 and a mounting cavity 9 (e.g., ...). Figure 4 As shown), a limiting member 16 is installed in the mounting cavity 9. The rotary pushing mechanism 5 includes a sliding member 11 that is reset by the reset spring and a rotating member 10 that is fixedly connected to the rotating rod 4. The rotating member 10 is rotatably installed in the rotating cavity 8, and the sliding member 11 is slidably installed in the limiting member 16. The reset spring is installed between the limiting member 16 and the sliding member 11 to prevent the sliding member 11 from directly detaching from the mounting cavity 9. The sliding member 11 is provided with an extension rod 7 that extends out of the limiting member 16. The end face of the extension rod 7 abuts against the micro switch 18.

[0030] The rotating member 10 has a V-groove 12 at one end near the sliding member 11, and the sliding member 11 has a V-shaped protrusion 13 corresponding to the V-groove 12. The V-shaped protrusion 13 is engaged in the V-groove 12. When the rotating member 10 rotates, the V-shaped protrusion 13 disengages from the V-groove 12 as the V-groove 12 rotates, thereby achieving a rotational pushing effect. When the rotating member 10 rotates in the opposite direction, the return spring pushes the sliding member 11 back towards the rotating member 10. This allows the V-shaped protrusion 13 to be re-engaged in the V-shaped groove 12. Alternatively, the rotary pushing mechanism 5 can also employ other common mechanisms capable of achieving this effect, such as a first arc-shaped protrusion on the rotating member 10 and a second arc-shaped protrusion on the sliding member 11 corresponding to the first arc-shaped protrusion. When the rotating member 10 rotates, the second arc-shaped protrusion gradually moves away from the rotating member 10 along the edge of the first arc-shaped protrusion, thus achieving the sliding effect of the sliding member 11.

[0031] The limiting member 16 is provided with a sliding groove 14, and the sliding member 11 is provided with a slider part 15 corresponding to the sliding groove 14. The slider part 15 is slidably installed in the sliding groove 14.

[0032] The reset spring is mounted on the protruding rod 7.

[0033] This invention only addresses how the rear ball uses the clutch structure of the front ball to achieve unlocking and locking functions; the rest of the intelligent ball lock structure remains unchanged.

[0034] In this product, when the rear ball 1 rotates, the front ball 2 is controlled to rotate by a rotating rod. Finally, the front ball 2 is linked with the clutch mechanism to realize the unlocking and opening function. That is, the rear ball 1 does not directly transmit power to the latch, but controls the front ball through the rear ball and then transmits power to the latch.
