[0017] 2. The locking device, when locking, drives the locking beads toward the center line of the locking rod, increasing the friction between the beads and the rope, forming a locked state and securing the rope to the smart lock body. When unlocking, the locking beads are driven away from the center line by contact, thereby reducing the friction between the beads and the rope, forming an unlocked state and releasing the fixation between the smart lock body and the rope.

During the movement of the drive shaft, the locking driver is driven toward the outlet terminal via the connector, causing the small end of the through hole to gradually approach and press against the locking bead, increasing the friction between the locking bead and the rope, thereby locking the rope. Simultaneously, the movement of the connector compresses the first elastic member mounted on the drive rod. During unlocking, the motor is activated by the unlocker, causing the rotor mounted on the motor to rotate. When the receiving groove on the rotor mates with the locking bead, the elastic force of the first elastic member on the drive shaft drives the locking bead away from the stop groove, at which point the locking bead is accommodated in the receiving groove. After separating from the locking bead, the drive shaft continues to move under the action of the first elastic member, thereby driving the locking driver toward the inlet terminal via the connector, thereby unlocking the rope. This type of passive smart lock not only makes it easier for users to use and improves the safety of goods after packaging, but also effectively avoids wear and scratches and ensures the convenience of unlocking.

DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0032] This embodiment relates to a passive smart lock with an ink screen, such as Figure 1-2 As shown, it includes: a smart lock body and an unlocker (not shown in the drawings) that is communicatively connected to the smart lock body.

[0033] Among them, the smart lock body includes: a shell 100, a locking device 200, a driving device 300, an unlocking device 400, a control circuit board 500 and an ink screen 600.

[0034] Specifically, the locking device 200 is disposed within the housing 100 and is used to lock or unlock an inserted rope. The driving device 300 is also disposed within the housing 100 and is used to drive the locking device 200 to lock or unlock. In this embodiment, the driving device 300 is manually actuated to lock the locking device 200. The unlocking device 400 is disposed within the housing 100. When the driving device 300 is manually actuated to the locked position, the unlocking device 400 restricts the movement of the driving device 300. During unlocking, the unlocking device 400 releases the restriction on the driving device 300, causing it to automatically return to the unlocked position. The control circuit board 500 is disposed within the housing 100 and is connected to the unlocking device 400. The control circuit board 500 is connected to the unlocker and controls the movement of the unlocking device 400 based on signals from the unlocker. During unlocking, the unlocker senses and supplies power to the control circuit board 500. The ink screen 600 is disposed on the outer wall of the housing 100 and is used to connect to the control circuit board 500 .

[0035] It should be noted that the ink screen 600 is an electronic ink screen, which can still display information after power failure. The ink screen 600 configured in this way can enable the smart lock to have the function of an electronic tag, thereby facilitating user identification.

[0036] Furthermore, if Figure 3-5 As shown, the drive device 300 includes a locking driver 310, a drive shaft 320, a connecting member 330, and a first elastic member 340. Specifically, the locking driver 310 is sleeved on the locking device 200 and is able to slide relative to the locking device 200. The drive shaft 320 extends through the housing 100 and is able to slide relative to the housing 100. The drive shaft 320 is used to allow the user to manually lock the lock or to engage with the unlocking device 400. One end of the connecting member 330 is fixedly mounted on the drive shaft 320, and the other end abuts the locking driver 310. The connecting member 330 can move synchronously with the drive shaft 320 and is used to drive the locking driver 310 to move relative to the locking device 200. The first elastic member 340 is sleeved on the drive shaft 320. When the user performs a manual locking action, the first elastic member 340 is in a compressed state; when the user performs an unlocking action, the first elastic member 340 drives the drive shaft 320, the connecting member 330 and the locking drive member 310 to return to the unlocking position.

[0037] Preferably, a mounting groove is provided in the housing 100 , and the first elastic member 340 is accommodated in the mounting groove, with one end of the first elastic member 340 fixedly mounted on the side wall of the mounting groove and the other end abutting against the connecting member 330 .

[0038] Furthermore, if Figure 3-5As shown, the drive shaft 320 is provided with a mounting notch 301, and the locking driver 310 is provided with an abutment groove 302. The connecting member 330 includes a fixing portion 331, a driving portion 332, and an auxiliary fixing portion 333. The fixing portion 331 is disposed within the mounting notch 301 and is fixedly assembled with the drive shaft 320. The driving portion 332 is integrally formed with the fixing portion 331 and extends toward and is assembled with the abutment groove 302. The auxiliary fixing portion 333 is disposed on the fixing portion 331 and is located between the drive shaft 320 and the locking driver 310.

[0039] It should be noted that there are two abutment grooves 302, and correspondingly, there are two connecting members 330. Two fixing grooves 303 are symmetrically disposed within the abutment groove 302, and two fixing posts 334 are correspondingly disposed on the fixing portion 331. During assembly of the fixing portion 331, the fixing posts 334 cooperate with the fixing grooves 303, thereby enhancing the stability of the assembly between the fixing portion 331 and the drive shaft 320. Furthermore, the provision of the auxiliary fixing portion 333 not only assists in the secure assembly of the fixing portion 331, but also forms a barrier between the drive shaft 320 and the locking driver 310, thereby ensuring non-contact between the drive shaft 320 and the locking driver 310, thereby ensuring stable operation of the drive device 300.

[0040] Furthermore, if Figure 3 、 4 As shown in Figures 6 and 7, the unlocking device 400 includes: a power source 410, a transmission member 420, a rotor 430, a limit member 440, and a torsion spring 450. Specifically, the power source 410 is fixedly mounted in the housing 100 and is electrically connected to the control mainboard. The transmission member 420 is fixedly mounted on the power output shaft of the power source 410, and the transmission member 420 can rotate synchronously with the power output shaft. The rotor 430 is sleeved on the transmission member 420 and can rotate with the transmission member 420. The limit member 440 is arranged in the housing 100 and is located between the rotor 430 and the drive shaft 320. The limit member 440 is used to cooperate with the drive shaft 320 to limit the drive shaft 320. The torsion spring 450 is sleeved on the rotor 430 on the side away from the transmission member 420, with one end fixedly assembled with the rotor 430 and the other end fixedly assembled with the upper housing 100.

[0041] It should be noted that a limiting groove 304 is provided on the side of the drive shaft 320 close to the limiting member 440. An accommodating groove 401 is provided on the rotor 430. An arc-shaped groove is provided on the shell 100, and the limiting member 440 is installed in the arc-shaped groove. When the user performs a manual locking action, the drive shaft 320 moves relative to the limiting member 440 until the limiting member 440 cooperates with the limiting groove 304 to limit the drive shaft 320. At the same time, the rotor 430, driven by the torsion spring 450, separates the limiting member 440 from the accommodating groove 401 and pushes the limiting member 440 into the limiting groove 304. The power source 410 immediately drives the transmission member 420 to reverse, thereby making room for the torsion spring 450 to reverse when unlocking. At this time, the smart lock is in a locked state. When the user performs the unlocking action, the power source 410 drives the rotor 430 to rotate, causing the accommodating groove 401 on the rotor 430 to rotate to the position where the limit member 440 is located. The limit member 440 separates from the limit groove 304 and is accommodated in the accommodating groove 401. The drive shaft 320 moves under the elastic force of the first elastic member 340. After the drive shaft 320 returns to the unlocked position, the rotor 430 reverses under the force of the torsion spring 450, thereby separating the accommodating groove 401 from the limit member 440. During the unlocking movement of the drive shaft 320, and after the rotor 430 drives the accommodating groove 401 to reach the position, the drive shaft 320, driven by the first elastic member 340, uses its side wall to push the limit member 440 into the accommodating groove 401, and causes the rotor 430 to stay in the unlocked position. At this time, the torsion spring 450 is in a compressed state. In this embodiment, the limiting member 440 is a limiting ball, the power source 410 is an electric motor, and the first elastic member 340 is a spring.

[0042] Preferably, if Figure 3 、 4 As shown in Figures 6 and 7, a limit platform 111 is provided inside the housing 100, and a limit protrusion 431 is provided on the rotor 430. The limit protrusion 431 is used to cooperate with the limit platform 111 on the housing 100 to prevent the rotor 430 from overrotating. When the rotor 430 rotates forward, the rotor 430 applies a force to the torsion spring 450. While being forced, the torsion spring 450 accumulates elastic potential energy, generating a tendency to move in the opposite direction, thereby preventing the rotor 430 from rotating and acting as a brake for stopping the rotor 430. When the rotor 430 rotates reversely, the torsion spring 450 provides power for the reverse movement of the rotor 430 through the accumulated elastic potential energy.

[0043] Furthermore, if Figure 3 、 4As shown in Figures 7-9, the housing 100 is provided with a through hole 101 for the rope to pass through. The locking device 200 includes: an inlet terminal 210, an outlet terminal 220, an outlet sleeve 230, a locking member 240, and a second elastic member 250. Specifically, the inlet terminal 210 is arranged in the housing 100 and docked with the entrance of the through hole 101. The outlet terminal 220 is arranged in the housing 100 and docked with the exit of the through hole 101. The outlet sleeve 230 is fixedly mounted on the outlet terminal 220 on the side close to the inlet terminal 210. The locking member 240 is sleeved in the outlet sleeve 230. The locking member 240 can move relative to the outlet sleeve 230 to move away from or closer to the inlet terminal 210. The second elastic member 250 is arranged in the outlet sleeve 230. One end of the second elastic member 250 is assembled with the line terminal 220, and the other end is assembled with the locking member 240. The second elastic member 250 is used to press the locking member 240 toward the line terminal 210.

[0044] Preferably, an anti-slip portion 231 is provided on the outlet sleeve 230 near the inlet terminal 210. A through hole 305 is provided on the locking drive 310. The through hole 305 is cup-shaped as a whole, and the cross-sectional area near the outlet sleeve 230 is larger than the cross-sectional area near the inlet terminal 210.

[0045] Furthermore, if Figure 3 、 4 As shown in Figures 7-9, the locking member 240 includes: a locking rod 241, an anti-slip platform 242 and a locking bead 243. One end of the locking rod 241 is installed in the outlet sleeve 230, and the other end is sleeved in the through hole 305. A accommodating groove 201 is provided on the locking rod 241 near the incoming terminal 210. The anti-slip platform 242 is provided on the locking rod 241 near the outlet terminal 220. The anti-slip platform 242 is located in the outlet sleeve 230 and cooperates with the anti-slip portion 231 to prevent the locking rod 241 from detaching from the outlet sleeve 230. The locking bead 243 is accommodated in the accommodating groove 201 and can move relative to the housing 100.

[0046] It should be noted that when performing the locking operation, the locking drive 310 moves toward the side of the outlet terminal 220, and the inner wall of the through hole 305 squeezes the locking bead 243 and makes it gather toward the axis of the locking rod 241 to press and lock the rope; when performing the unlocking operation, the locking drive 310 moves toward the side of the inlet terminal 210, and the locking bead 243 gradually separates from the inner wall of the through hole 305, and the pressing lock between the locking bead 243 and the rope is released.

[0047] Furthermore, if Figure 1-4As shown, the housing 100 includes a lower shell 110 and an upper cover 120, which are fastened together by screws. The ink screen 600 is fixedly mounted on the upper cover 120, and a sensing terminal (not shown in the figure) is provided on the control circuit board 500. The sensing terminal is wirelessly connected to the unlocking device.

[0048] In this embodiment, a charging capacitor (not shown in the drawings) is provided on the control circuit board 500. The sensing terminal is an NFC terminal. When unlocking, the unlocker is placed close to the smart lock body so that a connection is established between the NFC terminal and the unlocker, and the wireless signal transmitted by the unlocker is received. The wireless signal includes unlocking energy and communication information. Among them, part of the energy is converted into electrical energy to charge the "energy storage capacitor", and after "power rectification", a stable power supply is formed to power the "control circuit board 500" and "power source 410". The communication signal is sent to the MCU control chip on the control circuit board 500, which parses the information and controls the power source 410 according to the parsed instructions, and causes the power source 410 to drive the rotor 430 to move until the accommodating groove 401 on the rotor 430 docks with the limit ball, so that the limit ball squeezes the limit ball into the accommodating groove 401 when the first elastic member 340 drives the drive shaft 320 to move, forming an unlocked state. In other embodiments, the sensing terminal can also be a UHF RFID antenna terminal or a wired unlocking terminal. When the sensing terminal is a wired unlocking terminal, the wired communication and power supply interface is used to power the control circuit board 500 and the power source 410 via a wired method, and communicates with the MCU control chip via a wired method. The unlocking process is the same as the passive unlocking process.

[0049] The working principle of this embodiment is roughly as follows: the manual locking and automatic unlocking of the smart electronic lock are achieved by means of the provided driving device 300 and unlocking device 400. When performing the manual locking operation, the user manually pushes the driving shaft 320 to move, so that the limiting groove 304 on the driving shaft 320 cooperates with the limiting member 440 to complete the locking operation. During the movement of the driving shaft 320, the locking driving member 310 is driven to move toward the side of the outlet terminal 220 through the connecting member 330, so that the small end component of the through hole 305 approaches and presses against the locking bead 243, thereby increasing the friction between the locking bead 243 and the rope, thereby achieving the locking of the rope; at the same time, as the connecting member 330 moves, the first elastic member 340 sleeved on the driving rod is in a compressed state. During the unlocking operation, the motor is started to rotate by the unlocker, causing the rotor 430 mounted on the motor to rotate. When the receiving groove 401 on the rotor 430 is docked with the locking bead 243, the drive shaft 320, under the elastic force of the first elastic member 340, drives the locking bead 243 to separate from the limiting groove 304. At this time, the locking bead 243 is accommodated in the receiving groove 401. After separating from the locking bead 243, the drive shaft 320 continues to move under the action of the first elastic member 340, thereby driving the locking drive member 310 to move toward the side of the incoming wire end 210 through the connecting member 330, thereby realizing the unlocking operation of the locking device 200 on the rope. This passive smart lock is not only convenient for users to use and improves the safety of goods after packaging, but also can effectively avoid the problems of wear and scratching, ensuring the convenience of unlocking.

[0050] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
