[0039] Reference below Figures 1-5 The smart lock mechanism according to an embodiment of the present invention is described.

[0040] like Figures 1-5 As shown, the smart lock mechanism of this embodiment is used in conjunction with a door lock device. The smart lock mechanism includes a shell 100, a lock claw structure 120, a transmission structure 110, a trigger structure, a pressing structure 340 and an elastic reset member 350.

[0041] The pawl structure 120 is located on one side of the housing 100 and is mounted on the door lock knob. The transmission structure 110 is located within the housing 100, with one end connected to the pawl structure 120 for driving the pawl structure 120. Specifically, the pawl structure 120 is primarily used to clamp the door lock knob. The transmission structure 110 is a gear assembly that is in transmission connection with the pawl structure 120. The drive motor 220 drives the gear assembly, which drives the pawl structure 120 to rotate, thereby rotating the door lock knob to unlock or lock.

[0042] The trigger structure includes a trigger member 331 and a signal trigger unit 332. The trigger member 331 is used to trigger the signal trigger unit 332 to generate a feedback signal. The pressing structure 340 is provided on the side of the housing 100 opposite the locking claw structure 120 and is connected to the trigger member 331. The elastic return member 350 is connected to the pressing structure 340 and is used to reset the position of the pressing structure 340.

[0043] When the pressing structure 340 is pressed, the pressing structure 340 pushes the trigger member 331 to trigger the signal trigger unit 332, and the signal trigger unit 332 feeds back a signal to activate the transmission structure 110. When the pressing force is released, the pressing structure 340 and the trigger member 331 return to their original positions under the action of the elastic return member 350.

[0044] Further, if Figure 4 and Figure 5 As shown, the mounting base 310 is also included, which is connected to the other end of the transmission structure 110. The mounting base 310 is sleeved around the periphery and fixedly connected to a rotating member 320. The rotating member 320 is used to drive the transmission structure 110 and thus the locking pawl structure 120. Specifically, the rotating member 320 is used to manually drive the transmission structure 110 and can be used as a handle. The user drives the mounting base 310 through the rotating member 320, causing the mounting base 310 and the transmission structure 110 to rotate synchronously, thereby driving the locking pawl structure 120 to work, achieving manual rotation unlocking.

[0045] Furthermore, the pressing structure 340 is at least partially disposed on the inner periphery of the rotating member 320. That is, in the initial state, the pressing structure 340 is partially located inside the rotating member 320 and partially protrudes from the end surface of the rotating member 320 to form a protruding end, which facilitates the user to locate and push the pressing structure 340.

[0046] The signal trigger unit 332 is disposed at the bottom of the mounting base 310, and the trigger member 331 is movably coupled to the mounting base 310, meaning that the trigger member 331 can independently move along the axial direction of the mounting base 310. When the trigger member 331 moves and abuts the signal trigger unit 332, the signal trigger unit 332 can provide a feedback signal to activate the transmission structure 110, thereby implementing a push-to-unlock unlocking method and improving the user's manual unlocking experience.

[0047] In some embodiments of the utility model, as shown in Figure 4 and Figure 5 , the pressing structure 340 includes a button 341 and a connecting piece 342, one end of the connecting piece 342 is connected with the trigger piece 331, the other end of the connecting piece 342 is connected with the button 341, and the pressing structure 340 and the trigger piece 331 are axially movable along the mounting seat 310.

[0048] Specifically, the connecting piece 342 can move synchronously after being connected with the trigger piece 331, the stroke of the button 341 is consistent with the moving stroke of the trigger piece 331, the stroke virtual position of the trigger piece 331 is reduced, the pressing feeling is improved, and the response speed of the smart lock mechanism is faster.

[0049] In some embodiments of the utility model, as shown in Figure 4 and Figure 5 , the connecting piece 342 is provided with a guide column 343, the mounting seat 310 is provided with a guide groove 311, the elastic reset piece 350 is arranged in the guide groove 311, the elastic reset piece 350 is arranged in the guide groove 311, and the elastic reset piece 350 is sleeved or connected with the guide column 343.

[0050] Specifically, the elastic reset piece 350 is sleeved on the guide column 343 and abuts against one end of the connecting piece 342, the guide column 343 is at least partially arranged in the guide groove 311, and the other end of the elastic reset piece 350 abuts against the bottom of the guide groove 311. The axial movement of the guide column 343 along the guide groove 311 makes the trigger piece 331 move in a specific direction. The elastic potential energy of the elastic reset piece 350 between the connecting piece 342 and the mounting seat 310 increases during the pressing process, and when the external force of the connecting piece 342 is removed, the elastic reset piece 350 releases the potential energy and pushes the connecting piece 342 to move, so that the whole pressing structure 340 is reset, and the elastic reset piece 350 can be a spring.

[0051] In some embodiments of the utility model, as shown in Figure 1 , Figure 3 and Figure 4 , the button 341 covers the top of the mounting seat 310 and / or the inner circumferential opening of the rotating piece 320. Specifically, the rotating piece 320 is a ring structure, which is wrapped around the circumference of the mounting seat 310, the middle part of the rotating piece 320 is hollow, the middle hollow part of the rotating piece 320 is covered by the button 341 to form the outer wall surface of the rotating piece 320, which plays a role of covering the mounting seat 310 and can be pressed independently of the rotating piece 320. The user can realize two unlocking modes of pressing or rotating with one hand, and the user experience is improved.

[0052] In some embodiments of the utility model, as shown in Figure 4 and Figure 5As shown, the trigger member 331 is sleeved on the outer wall of the mounting base 310. A limit block 312 is provided on the outer periphery of the mounting base 310. The limit block 312 abuts the end surface of the trigger member 331 to limit the movement of the trigger member 331. Specifically, the trigger member 331 abuts the limit block 312, and the connecting member 342 is connected to the trigger member 331. The travel of the pressing structure 340 is also limited by the limit block 312, thereby preventing the elastic force of the elastic return member 350 from separating the pressing structure 340 from the mounting base 310. This ensures the secure installation of the pressing structure 340 while also limiting the movement between the trigger member 331 and the signal trigger unit 332. By changing the height of the limit block 312, the trigger travel of the trigger member 331 can be changed, thereby adjusting the pressing feel.

[0053] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, one of the periphery of the mounting seat 310 and the inner periphery of the rotating member 320 is provided with a clamping portion 313, and the other is provided with a clamping groove 314. The clamping portion 313 and the clamping groove 314 cooperate with each other to fix the mounting seat 310 to the rotating member 320.

[0054] Specifically, the mounting seat 310 can expand its diameter by extending the clamping portion 313 , so that the rotating member 320 can adopt a larger diameter, thereby improving the grip feel.

[0055] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the smart lock mechanism also includes a connecting shaft 410, which is inserted between the mounting base 310, the transmission structure 110, and the locking claw structure 120. The end of the connecting shaft 410 is installed with a fastener for fixing the mounting base 310, the transmission structure 110, and the locking claw structure 120. The connecting shaft 410 connects the three into a whole, and the mounting base 310 synchronously drives the transmission structure 110 and the locking claw structure 120 to rotate. The fastener can be a screw or a latch.

[0056] In some embodiments of the present invention, Figure 5 As shown, the signal trigger unit 332 is a micro switch, and the trigger member 331 is used to abut against the micro switch.

[0057] The smart lock mechanism also includes a control unit 210 and a drive motor 220. The drive motor 220 is connected to the transmission structure 110. The control unit 210 is electrically connected to the drive motor 220 and the signal trigger unit 332 respectively, and is used to receive the signal from the signal trigger unit 332 and drive the drive motor 220 to drive the transmission structure 110 to work.

[0058] Specifically, when the trigger member 331 presses the micro switch, an electrical signal is generated, thereby activating the transmission structure 110. Other switch structures may also be used to generate electrical signals. The present invention does not describe the switch structure of the signal trigger unit 332 in detail. It should be understood that, without departing from the basic concept of the present invention, flexible changes in the switch structure of the signal trigger unit 332 should be considered within the scope of protection defined by the present invention.

[0059] In some embodiments of the present invention, Figure 5 As shown, the signal trigger unit 332 is provided with at least one set of micro switches around the bottom of the trigger member 331. In this embodiment, multiple micro switches are provided. Specifically, to improve the sensitivity of the trigger structure and facilitate the user to trigger the signal trigger unit 332 by pressing the button 341 from any position, multiple micro switches are provided at equal intervals around the bottom periphery of the trigger member 331, so that pressing the button 341 from any angle can trigger the micro switches on the signal trigger unit 332.
