[0021] Reference Figures 1-6 The image shown is a preferred embodiment of the present invention.

[0022] The smart lock stacked unlocking assembly provided by this utility model includes a housing 100, which has a cavity. The upper part of the cavity forms an upper cavity 101, and the lower part of the cavity forms a lower cavity 102. A lock cylinder 200 is arranged horizontally in the upper cavity 101, and a drive motor 300 is arranged horizontally in the lower cavity 102. A telescopic push rod 310 is connected to the front end of the drive motor 300. The drive motor 300 and the lock cylinder 200 are stacked vertically. The front end of the lock cylinder 200 is provided with a movable seat 400. The front surface of the movable seat 400 is provided with a plurality of forward-protruding pin shafts 420. The front part of the plurality of pin shafts 420 is sleeved on the pin seat 500. A square shaft rotating shaft 600 is arranged in front of the pin seat 500. The movable seat 400 has a lower extension plate 410 extending downward into the lower cavity 102. The lower extension plate 410 is arranged in front of the telescopic push rod 310.

[0023] The smart lock's stacked unlocking assembly described above has a lock cylinder 200 arranged horizontally in the upper cavity 101 and a drive motor 300 arranged horizontally in the lower cavity 102. The two are arranged in a compact stacked layout, which greatly optimizes the space occupation. The front end of the drive motor 300 is equipped with an axially extendable telescopic push rod 310, which serves as the core execution component for power output.

[0024] Next, a movable base 400 is connected to the front end of the lock cylinder 200. Multiple forward-protruding pin shafts 420 are integrally formed on the front surface of the movable base 400. The front of each pin shaft 420 is movably fitted onto a pin seat 500 fixed within the housing 100, providing stable guidance for the pin shaft 420. Simultaneously, a lower extension plate 410 extends integrally from the movable base 400, pointing downwards into the lower cavity 102. The front of the telescopic push rod 310 is positioned directly opposite the lower extension plate 410, ensuring precise power transmission. During unlocking, the drive motor 300 drives the telescopic push rod 310 forward, which, upon contact with the lower extension plate 410, pushes the movable base 400 forward synchronously. Guided by the pin seat 500, the pin shaft 420 precisely connects with the square shaft 600, achieving unlocking. This stacked design significantly reduces component size, adapting to the miniaturization requirements of smart locks.

[0025] Specifically, the movable base 400 is provided with multiple transverse through-holes, and multiple pin shafts 420 are correspondingly inserted into the pin holes. In this way, the pin holes guide the transverse movement of the pin shafts 420, preventing the pin shafts 420 from deviating and ensuring higher accuracy when docking with the square shaft rotating shaft 600.

[0026] The rear end face of the square shaft 600 is provided with multiple groove-shaped mating holes 601, which are aligned with multiple pin holes. The front end face of the square shaft 600 is provided with groove-shaped fitting holes 602 for the square shaft to be inserted. In this way, the mating holes 601 are aligned with the pin holes to ensure accurate insertion of the pin shaft 420, improving the reliability of the unlocking action. Furthermore, the fitting holes 602 tightly engage with the square shaft to ensure effective torque transmission and enhance the overall structural linkage.

[0027] In a specific implementation, when electronic unlocking is used, the circuit board brain sends a command to the drive motor 300, which drives the telescopic push rod 310 to push the moving seat 400, so that the pin shaft 420 is connected to the square shaft rotating shaft 600. Then, the square shaft rotating shaft 600 rotates with the square shaft, and the smart lock can be opened.

[0028] In a preferred embodiment, a spring is sleeved on the outer periphery of the pin shaft 420, and the rear part of the pin hole expands radially outward to form an annular groove for the spring to be inserted. In this way, after unlocking, the spring force can drive the pin shaft 420 to automatically return to its original position without the need for an additional reset structure.

[0029] The lower cavity 102 has a partition in the middle, which divides the lower cavity 102 into a front cavity and a rear cavity. The front cavity has a moving module 700 and the rear cavity has a drive motor 300. The partition has a transverse through-hole in the middle. The top of the moving module 700 is recessed downward to form a mounting groove 701. The rear end face of the moving module 700 has a module hole that communicates with the mounting groove 701. The lower extension plate 410 is inserted into the mounting groove 701 from top to bottom. The front end of the telescopic push rod 310 passes through the partition hole and the module hole into the mounting slot 701. This ensures precise guidance: the push rod 310 transmits power through the partition hole and the module hole, and works with the mounting slot 701 to limit the lower extension plate 410, thereby improving transmission stability.

[0030] Specifically, the front of the mounting slot 701 forms a locking part 702, and the lower part of the lower extension plate 410 is engaged in the locking part 702, so that the lower extension plate 410 is fixedly connected to the moving module 700. This improves the transmission stability.

[0031] In a preferred embodiment, a central plate 710 is provided in the mounting slot 701, which divides the mounting slot 701 into front and rear sections. The central plate 710 has a transverse through-hole, through which the front end of the telescopic push rod 310 passes. Thus, by adding the central plate 710 and the central hole, the guiding performance is further enhanced. Furthermore, the central plate 710 divides the mounting slot 701, increasing the overall rigidity of the moving module 700 and reducing deformation during power transmission.

[0032] The lock cylinder 200 has a keyhole 201 formed on its rear end face for inserting a key. The keyhole 201 is designed to allow for unlocking with a mechanical key.

[0033] Specifically, by inserting the key into the keyhole 201 and rotating the key, the device inside the lock cylinder 200 is triggered, the front end of the lock cylinder 200 extends and moves forward against the movable seat 400, so that the pin shaft 420 is connected to the square shaft rotating shaft 600. Then, the square shaft rotating shaft 600 rotates with the square shaft, and the smart lock can be opened.

[0034] The device inside the lock cylinder 200 can be a linkage structure between the pin assembly and the paddle. After the key is inserted, its teeth match the pins. When the key is rotated, the paddle inside the lock cylinder 200 rotates, and the paddle pushes the telescopic component at the front end of the lock cylinder 200 to extend.

[0035] In a preferred embodiment, the top of the housing 100 has a hollowed-out strip groove 103, which communicates with the upper cavity 101. The top of the lock cylinder 200 has an upwardly protruding upper ridge 210, which extends along the length of the lock cylinder 200 and passes through the strip groove 103. This facilitates the positioning and installation of the lock cylinder 200 into the housing 100, as well as the removal of the lock cylinder 200, resulting in a more compact connection between the overall structures.

[0036] In a preferred embodiment, a mounting plate 110 is connected to the outer periphery of the housing 100. The mounting plate 110 is integrally formed with the housing 100, and the mounting plate 110 is provided with a plurality of mounting holes 111. The housing 100 is fixed to the carrier by the mounting plate 110 and the mounting holes 111. This facilitates the quick fixing of the component to the carrier by fasteners, and the carrier can be a smart door lock component.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
