[0021] Reference Figures 1-5 The image shown is a preferred embodiment of the present invention.
[0022] The minimalist smart lock provided by this utility model includes an outer handle 100, an inner handle 200, and a lock body 300 for installation on a door. The lock body 300 is arranged between the outer handle 100 and the inner handle 200. The outer handle 100 includes an outer shell 101, which has an outer shell cavity. An outer lock assembly 400 is provided in the outer shell cavity. The outer lock assembly 400 includes an outer lock housing 401, which has an upper cavity and a lower cavity. The upper cavity and the lower cavity are arranged vertically and are interconnected. A lock cylinder 410 is provided in the upper cavity, and a drive motor 420 is provided in the lower cavity. The drive motor 420 is connected to a telescopic push rod. The drive motor 420 and the lock cylinder 410 are stacked vertically. The front end of the lock cylinder 410 is provided with a movable seat 430, the movable seat 430 has a lower extension plate 431 extending downward into the lower cavity, the lower extension plate 431 is arranged in front of the telescopic push rod, and the front end face of the movable seat 430 is provided with a plurality of forward-protruding pin shafts; the external lock assembly 400 includes a square shaft 450, the square shaft 450 is arranged in front of the movable seat 430, the rear end face of the square shaft 450 is provided with a plurality of pin holes, and a square shaft is connected to the square shaft 450; The inner handle 200 includes an inner housing with an inner cavity. One end of the square shaft is fixedly connected to the square shaft rotating shaft 450, and the other end of the square shaft is fixedly embedded in the inner cavity. The middle part of the square shaft passes through the lock body 300.
[0023] The aforementioned minimalist smart lock features a lock cylinder 410 arranged horizontally in the upper cavity and a corresponding drive motor 420 arranged horizontally in the lower cavity. The two are arranged in a compact, stacked layout, which greatly optimizes space utilization. The front end of the drive motor 420 is equipped with an axially extendable telescopic push rod, which serves as the core actuator for power output.
[0024] Next, a movable base 430 is connected to the front end of the lock cylinder 410. The front face of the movable base 430 has multiple forward-protruding pins. The movable base 430 integrally extends a lower extension plate 431 that extends downward into the lower cavity. The front of the telescopic push rod is positioned directly opposite the lower extension plate 431 to ensure precise power transmission. Furthermore, both ends of the square shaft are fixed in the outer handle 100 and the inner handle 200, respectively. During unlocking, the drive motor 420 drives the telescopic push rod forward, which, after contacting the lower extension plate 431, pushes the movable base 430 forward synchronously, precisely connecting the pins with the square shaft rotating shaft 450. Unlocking is achieved by rotating the square shaft. This stacked design significantly reduces component size, adapting to the miniaturization requirements of smart locks.
[0025] In a specific implementation, when electronic unlocking is used, the circuit board brain sends a command to the drive motor 420, which drives the telescopic push rod to push the moving seat 430, so that the pin shaft is connected to the square shaft rotating shaft 450. Then, the square shaft rotating shaft 450 rotates with the square shaft, and the lock tongue on the lock body 300 retracts, and the smart lock can be opened.
[0026] Specifically, a pin seat 440 is provided between the movable seat 430 and the square shaft 450, and the pin seat 440 is sleeved on multiple pin shafts. Through the design of the pin seat 440, the movement direction of the pin shaft is guided, so as to achieve precise docking between the pin shaft and the pin hole.
[0027] The outer casing 101 has an outer fixing seat 107 at its bottom, with an outer mounting hole formed therein, through which the square shaft passes out of the outer casing cavity. The inner casing has an inner fixing seat 202 at its bottom, with an inner mounting hole formed therein, through which the square shaft passes into the inner casing cavity. The lock body 300 has a square shaft hole, through which the middle part of the square shaft passes. In this way, the square shaft is connected to the lock body 300 through the square shaft hole, thereby controlling the locking tongue on the lock body 300.
[0028] Specifically, the outer fixed seat 107 is equipped with an outer retaining spring 105, which securely connects the outer fixed seat 107 to the square shaft; the inner fixed seat 202 is equipped with an inner retaining spring 204, which securely connects the inner fixed seat 202 to the square shaft. This ensures a stable connection, efficient transmission, ease of assembly and maintenance, stress buffering, and space saving, meeting the requirements of minimalist design and durability.
[0029] Specifically, an outer handle spring 106 is provided in the outer shell cavity, and the outer handle spring 106 is arranged around the outer periphery of the square shaft; an inner handle spring 205 is provided in the inner shell cavity, and the inner handle spring 205 is arranged around the outer periphery of the square shaft. In this way, the handle can be provided with a reset force to ensure that it automatically returns to its original position after rotation, while also buffering the impact force during operation, improving the feel and durability of the parts, and the surrounding layout does not take up extra space, fitting the overall compact design.
[0030] In a preferred embodiment, the outer shell cavity includes a panel shell 102, and an outer lock shell 401 is disposed within the panel shell 102. The panel shell 102 is connected to a telescopic rod 103, with one end of the telescopic rod 103 connected to the panel shell 102 and the other end connected to the outer shell 101. When the outer shell 101 is driven to move laterally outward, the telescopic rod 103 extends, exposing the panel shell 102. This allows the telescopic rod 103 to extend and expose the panel shell 102 as the outer shell 101 moves laterally, achieving both flexible movement of the outer shell 101 and structural stability through the telescopic rod 103 connection. Simultaneously, the exposed panel shell 102 meets operational or maintenance requirements, balancing functionality and structural rationality.
[0031] Specifically, the outer periphery of the panel housing 102 has a flat surface, on which the touch motherboard 104 is mounted. When the drive housing 101 moves laterally outward, the telescopic rod 103 extends, exposing the touch motherboard 104. In this way, the touch motherboard 104 is mounted on the flat surface of the outer periphery of the panel housing 102, and the extension of the telescopic rod 103 when the housing 101 moves laterally exposes the touch motherboard 104. This ensures the touch motherboard 104 is securely mounted using the flat surface, while the movement of the housing 101 allows for the concealment and exposure of the touch area, balancing ease of operation with a clean appearance.
[0032] The lock cylinder 410 has a keyhole on its outer surface. Under normal circumstances, the lock cylinder 410 is concealed in the outer casing 101, and the keyhole is also concealed.
[0033] Key opening: By inserting the key into the keyhole and rotating the key, the device inside the lock cylinder 410 is triggered. The front end of the lock cylinder 410 extends and moves forward against the moving seat 430, so that the pin shaft is connected to the square shaft rotating shaft 450. Then, the square shaft rotating shaft 450 rotates with the square shaft, and the smart lock can be opened.
[0034] The device inside the lock cylinder 410 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 410 rotates, and the paddle pushes the telescopic component at the front end of the lock cylinder 410 to extend.
[0035] Specifically, the inner housing is provided with an inner locking assembly, which is used to lock the lock body 300. The inner locking assembly can be a structure in which a moving shaft cooperates with a pin.
[0036] Specifically, an outer knob 110 is connected to the outer surface of the outer casing 101, and an outer light ring 120 is fixed to the outer surface of the outer knob 110; an inner knob 210 is connected to the outer surface of the inner casing, and an inner light ring 220 is fixed to the outer surface of the inner knob 210; a power supply 230 is provided in the inner casing cavity. In this way, the outer surfaces of the outer casing 101 and the inner casing are respectively connected to the outer knob 110 and the inner knob 210, and the outer light ring 120 and the inner light ring 220 fixed on their surfaces can provide intuitive status indications. With the power supply 230 in the inner casing cavity providing power, it not only enhances the convenience of operation and visual feedback, but also fits the simplicity and functionality of the design.
[0037] The outer fixing seat 107 is fixedly installed on the lock body 300, and an outer anti-slip flame-retardant pad 108 is clamped and fixed between the lock body 300 and the outer fixing seat 107. The inner fixing seat 202 is fixedly installed on the lock body 300, and an inner anti-slip flame-retardant pad 203 is clamped and fixed between the lock body 300 and the inner fixing seat 202. In this way, the outer shell 101 and the inner shell are fixed to the lock body 300 by the outer fixing seat 107 and the inner fixing seat 202, respectively, and the outer anti-slip flame-retardant pad 108 and the inner anti-slip flame-retardant pad 203 are clamped between the lock body 300 and the fixing seat, which not only enhances the stability and anti-slip effect of the connection, but also improves the safety performance through the flame-retardant pad, while ensuring the installation reliability of the overall structure.
[0038] In this embodiment, the outer handle 100 and the inner handle 200 are connected to each other through a connecting structure; The connection structure includes multiple screws 500, and the lock body 300 has multiple screw holes for the screws 500 to pass through. One end of the screw 500 is fixedly connected to the outer shell 101, and the other end of the screw 500 is fixedly connected to the inner shell. In this way, the two ends of the screw 500 fix the outer shell 101 and the inner shell respectively, which not only ensures the stability and integrity of the connection between the two, but also achieves precise positioning through the screw holes on the lock body 300, simplifies the assembly process, and results in a compact overall structure.
[0039] 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.
