Description

Technical Field

[0001] This utility model relates to the field of electronic lock technology, specifically to an electronic lock control circuit and an electronic lock. Background Technology

[0002] With the rapid development of smart IoT technology, electronic locks are widely used in various smart locker devices such as smart parcel lockers, smart gun lockers, and smart storage lockers. Modern electronic locks and their control systems are becoming increasingly feature-rich, needing not only to perform basic unlocking functions but also to monitor the locker's status and usage in real time to meet the demands of intelligent management.

[0003] Currently, the industry commonly uses a solution of adding microswitches to the mechanical structure of electronic locks to address the issue of cabinet status and usage detection. During the opening and closing of the electronic lock, changes in the mechanical structure trigger the microswitch to open or close. The lock control system then determines the smart cabinet's door opening / closing status based on the signal from the microswitch and monitors usage by recording the opening / closing time. However, this solution has significant drawbacks: First, to achieve the monitoring function, an additional signal monitoring line needs to be added to the original unlocking circuit of the electronic lock, increasing the number of lines from 2 to 4. For smart express lockers and smart storage lockers with numerous doors, each electronic lock requires an additional connection to the control circuit board. Since the main material of the wiring is expensive copper, this significantly increases the overall material cost. Second, the increased number of lines significantly increases the difficulty of production and installation, prolongs installation time, and reduces production efficiency. Third, more connection points increase the risk of circuit failure, reduce the reliability and stability of the electronic lock system, and increase subsequent maintenance costs.

Detailed Implementation

[0021] The present invention will be further described in conjunction with the following embodiments.

[0022] Depend on Figures 1 to 3 As can be seen, the electronic lock control circuit described in this embodiment includes a micro switch 1 and an electromagnet 2; the micro switch 1 includes a common terminal 13, a first terminal 11, and a second terminal 12; the electronic lock control circuit also includes a first power port 31, a signal acquisition module 32, a second power port 41, an on / off switch 42, and a negative port 51; the negative port 51 is connected to one end of the electromagnet 2; the other end of the electromagnet 2 is connected to the common terminal 13 of the micro switch 1; the first power port 31 is connected to the first terminal 11 of the micro switch 1 through the signal acquisition module 32; the second power port 41 is connected to the first terminal 11 of the micro switch 1 through the on / off switch 42. In this embodiment, the first power port 31 is connected to a 5V power supply. In this embodiment, the second power port 41 is connected to a 12V power supply.

[0023] Specifically, in the electronic lock control circuit described in this embodiment, when the latch 9 and the housing 7 are in a locked state, the latch 9 is engaged with the stop 8, and the latch 9 is not in contact with the micro switch 1; that is, when the latch 9 and the housing 7 are in a locked state, the common terminal 13 of the micro switch 1 is connected to the first terminal 11. At this time, the first power port 31, the signal acquisition module 32, the first terminal 11, the common terminal 13, the electromagnet 2, and the negative terminal 51 are in a closed circuit state, and the signal acquisition module 32 can feed back a signal. The system determines that the electronic lock is in the locked state. After the first power port 31 passes through the signal acquisition module 32, the signal acquisition module 32 is equipped with a step-down component, which reduces the voltage to zero volts, forming an equipotential with the negative port 51. This ensures that the first power port 31, the signal acquisition module 32, the first terminal 11, the common terminal 13, the electromagnet 2, and the negative port 51 are only a single path. No current flows through the electromagnet 2, so the electromagnet 2 cannot trigger the slide bar 71 and the stop 8 to act, thus keeping the electronic lock in its current locked state.

[0024] When unlocking is required, the on / off switch 42 is turned on, allowing the second power port 41 to be connected. At this time, the second power port 41, signal acquisition module 32, first terminal 11, common terminal 13, electromagnet 2, and negative terminal 51 are in a closed circuit state. Due to the high power voltage input to the second power port 41, the electromagnet 2 can trigger the sliding rod 71 and the stop 8 to act, thereby causing the stop 8 to separate from the hook 9. After the hook 9 resets, it forms an unlocked state with the housing 7. After the hook 9 resets, it triggers the micro switch 1 to act, causing the common terminal 13 to disconnect from the first terminal 11 and connect the common terminal 13 to the second terminal 12. At this time, the signal acquisition module 32 is in an open circuit state and cannot provide signal feedback. At this time, it is determined that the electronic lock is in an unlocked state.

[0025] This embodiment combines the unlocking circuit of the electronic lock with the signal monitoring circuit into one circuit, which effectively reduces production costs and difficulties, and shortens installation time.

[0026] This embodiment describes an electronic lock control circuit, which further includes a unidirectional diode 52. One end of the signal acquisition module 32 is connected to a first power port 31; the other end of the signal acquisition module 32 is connected to the anode of the unidirectional diode 52; the cathode of the unidirectional diode 52 is connected to the first terminal 11 of the micro switch 1; one end of the on / off switch 42 is connected to a second power port 41; the other end of the on / off switch 42 is connected to the cathode of the unidirectional diode 52; and the other end of the on / off switch 42 is connected to the first terminal 11 of the micro switch 1. Specifically, by using the unidirectional diode 52, this embodiment can prevent the second power port 41 from being connected to the signal acquisition module 32 during momentary unlocking.

[0027] The electronic lock control circuit described in this embodiment further includes a connector 6; the negative terminal 51 is connected to one end of the electromagnet 2 via the connector 6; the cathode of the unidirectional diode 52 and the other end of the on / off switch 42 are respectively connected to the first end 11 of the micro switch 1 via the connector 6. This arrangement facilitates signal connection.

[0028] The electronic lock described in this embodiment includes a housing 7 and an electronic lock control circuit; the housing 7 is provided with a slide rod 71, a stop 8, and a hook 9; the electromagnet 2 is used to drive the slide rod 71 to move; the stop 8 is rotatably disposed on the housing 7; the hook 9 is rotatably disposed on the housing 7; the stop 8 and the hook 9 are engaged; a coil spring is provided between the stop 8 and the housing 7 and between the hook 9 and the housing 7; the stop 8 is used to engage with the hook 9; the slide rod 71 is used to separate the stop 8 from the hook 9. The coil spring is not shown in the figure. When the hook 9 is locked to the housing 7, the hook 9 is engaged with the stop 8 and the hook 9 is not in contact with the micro switch 1. That is, when the hook 9 is locked to the housing 7, the common terminal 13 of the micro switch 1 is connected to the first terminal 11. At this time, the first power port 31, the signal acquisition module 32, the first terminal 11, the common terminal 13, the electromagnet 2, and the negative terminal 51 are in a closed circuit state. The signal acquisition module 32 can feed back a signal and determine that the electronic lock is in the locked state. Since the power supply voltage input to the first power port 31 is low, the electromagnet 2 cannot trigger the slide bar 71 and the stop 8 to act, so that the electronic lock maintains the current locked state.

[0029] When unlocking is required, the on / off switch 42 is turned on, allowing the second power port 41 to be connected. At this time, the second power port 41, signal acquisition module 32, first terminal 11, common terminal 13, electromagnet 2, and negative terminal 51 are in a closed circuit state. Due to the high power voltage input to the second power port 41, the electromagnet 2 can trigger the sliding rod 71 and the stop 8 to act, thereby causing the stop 8 to separate from the hook 9. After the hook 9 resets, it forms an unlocked state with the housing 7. After the hook 9 resets, it triggers the micro switch 1 to act, causing the common terminal 13 to disconnect from the first terminal 11 and connect the common terminal 13 to the second terminal 12. At this time, the signal acquisition module 32 is in an open circuit state and cannot provide signal feedback. At this time, it is determined that the electronic lock is in an unlocked state.

[0030] In this embodiment of the electronic lock, the stop member 8 is provided with a slot 81; the hook member 9 is provided with a locking block 91 that cooperates with the slot 81. The above arrangement facilitates the engagement of the stop member 8 and the hook member 9.

[0031] In this embodiment of the electronic lock, the latch 9 is provided with a pressing block 92 for abutting against the micro switch 1. This arrangement facilitates the latch 9 in triggering the micro switch 1.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
