The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0019] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, a smart cabinet door lock includes a housing 1, with a mounting bracket 2 fixedly installed inside the housing 1. A circuit board 3 and a drive mechanism are fixedly mounted on the mounting bracket 2, and the drive mechanism is electrically connected to the circuit board 3. A lock cylinder 4 is installed inside the housing 1, and the lock cylinder 4 is rotatably and limit-connected to the housing 1. An unlocking lever 5 is fixedly installed on one side of the lock cylinder 4, and a keyhole 6 is provided on the other side of the lock cylinder 4. The keyhole 6 is used to insert an unlocking key 7 to drive the unlocking lever 5 to rotate. During use, the user can insert the appropriate unlocking key 7 into the keyhole 6, and then rotate the unlocking key 7 to drive the lock cylinder 4 and the unlocking lever 5 to rotate, thus realizing the function of manually opening and closing the lock. This smart cabinet door lock retains the function of unlocking with a mechanical key. When the electronic unlocking fails, the lock can be opened with a mechanical key without damaging the cabinet lock, reducing the user's losses.

[0022] The lock head 4 is connected to the output of the drive mechanism, which drives the lock head 4 to rotate, thereby causing the unlocking lever 5 to rotate. In practice, a communication module such as Bluetooth can be integrated onto the circuit board 3. This module allows connection to a control terminal, such as a mobile phone or computer. When using electronic unlocking, the control terminal sends a control signal to the circuit board 3. Upon receiving the signal, the circuit board 3 immediately controls the drive mechanism to operate, causing the lock head 4 to rotate, which in turn drives the unlocking lever 5 to rotate, thus achieving the electronic unlocking function.

[0023] This smart cabinet door lock offers both electronic and mechanical key unlocking methods, enhancing its functionality. Users can choose the unlocking method according to their needs, thus improving user experience. On the other hand, retaining the mechanical key unlocking method allows for unlocking with the key in case the electronic unlocking system malfunctions, eliminating the need for forced entry and reducing the risk of property loss.

[0024] A protective door 8 is provided on the keyhole 6 to seal it. One end of the protective door 8 is hinged to the lock cylinder 4, and the protective door 8 can rotate and swing along the hinge. Normally, the protective door 8 blocks the keyhole 6. When the unlocking key 7 is inserted into the keyhole 6, the unlocking key 7 pushes the protective door 8 to rotate and swing along the hinge, thereby opening the keyhole 6, allowing the unlocking key 7 to be inserted into the keyhole 6 for mechanical unlocking. By providing a protective door 8 on the keyhole 6, the overall aesthetics of the smart cabinet door lock are improved; furthermore, sealing the keyhole 6 with the protective door 8 provides dust and water protection, reducing the entry of moisture and dust into the keyhole 6 and extending the lifespan of the smart cabinet door lock.

[0025] The drive mechanism includes a drive motor 9 and a transmission assembly. The drive motor 9 is fixedly mounted on the mounting bracket 2 and electrically connected to the circuit board 3. The transmission assembly is connected to the output end of the drive motor 9 and to the lock cylinder 4. When using electronic unlocking, the circuit board 3 controls the drive motor 9 to work. The drive motor 9 drives the transmission assembly to move, which in turn drives the lock cylinder 4 to rotate, thereby rotating the unlocking lever 5 to achieve the unlocking function.

[0026] In this embodiment, the transmission assembly includes a first gear 10, a second gear 11, and a third gear 12. The first gear 10 is connected to the output end of the drive motor 9. The third gear 12 is sleeved around the lock head 4 and is coaxially arranged with the lock head 4. The second gear 11 is mounted on the mounting bracket 2 and can rotate on the mounting bracket 2. The second gear 11 meshes with the first gear 10 and the third gear 12. When using electronic unlocking, the circuit board 3 controls the drive motor 9 to work. The drive motor 9 drives the first gear 10 to rotate, which in turn drives the second gear 11 and the third gear 12 to rotate. The third gear 12 drives the lock head 4 to rotate, and the lock head 4 drives the unlocking lever 5 to rotate, thereby realizing the electronic unlocking function.

[0027] In other embodiments, the second gear 11 may not be installed on the mounting bracket 2. The transmission assembly includes a first gear 10 and a third gear 12. The first gear 10 is connected to the output end of the drive motor 9, and the third gear 12 is sleeved on the periphery of the lock head 4 and is coaxially arranged with the lock head 4. The first gear 10 and the third gear 12 are meshed together. During electronic unlocking, the drive motor 9 drives the first gear 10 to rotate, which in turn drives the third gear 12 and the lock head 4 to rotate, thereby driving the unlocking lever 5 to rotate and realizing the electronic unlocking function.

[0028] The outer casing 1 includes a front casing 13 and a rear cover 14, which are fixedly connected by screws to form an internal mounting cavity, facilitating the installation of components such as the circuit board 3 and the drive motor 9. A mounting bracket 2 is fixedly installed within this mounting cavity, facilitating the fixation of the circuit board 3, the drive motor 9, and the second gear 11. A battery box 15 for installing a battery is provided on the front casing 13, and the battery box 15 is electrically connected to the circuit board 3. By installing a battery in the battery box 15, the battery can power the circuit board 3 to achieve the electronic unlocking function; in other embodiments, an external power supply or other methods can also be used to power the circuit board 3, which is not limited by this invention.

[0029] A battery cover 16 is installed on the battery compartment 15. The battery cover 16 is detachably connected to the battery compartment 15. The battery cover 16 facilitates the replacement of the batteries inside the battery compartment 15, improving practicality. When it is necessary to replace the batteries, the user only needs to open the battery cover 16 to remove the batteries from the battery compartment 15, replace them with new batteries, and then close the battery cover 16 again to complete the battery replacement.
