Description

Technical Field

[0001] This utility model relates to the field of electronic locks, specifically an electronic lock. Background Technology

[0002] An electronic lock is an electronic product that uses circuitry to control a mechanical switch to lock and unlock. With the continuous incorporation of advanced technologies into traditional locks, the security functions of locks have been fully extended and expanded, and electronic locks have become an indispensable component of today's security systems.

[0003] Existing electronic locks typically use a motor-driven bolt extension and retraction mechanism to unlock and lock. However, existing electronic locks lack status indication and emergency functions. The unlocking or locking status of the electronic lock cannot be intuitively fed back, which can easily lead to misjudgment of the electronic lock's status. Furthermore, when the electronic lock is without power or the circuit is damaged, it cannot operate normally. Therefore, an electronic lock is proposed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] An electronic lock, such as Figures 1-5 As shown, the hollow interior of the housing assembly forms a cavity, providing installation space for the lock plate 9, lock rod 10, indicator assembly, drive assembly, and emergency assembly. When the drive assembly is powered on, it drives the lock plate 9 to slide within the cavity, causing the lock plate 9 to extend and retract on the housing assembly. When the lock rod 10 extends, the electronic lock is in the locked state. The lock plate 9 presses against the indicator assembly, triggering it and generating a locked indicator signal to facilitate the determination of the electronic lock's status. When the lock plate 9 retracts, it disengages from the indicator assembly, generating an unlocking indicator signal. In the event of a power outage or circuit failure, the electronic lock can also be unlocked by manually activating the emergency assembly, enabling emergency unlocking.

[0027] The first-stage gear 5, the second-stage gear 6, and the third-stage gear 7 are all rotatably mounted inside the cavity on one side of the motor 3. The compact internal space of the electronic lock makes the installation space occupied by the electronic lock small.

[0028] The first-stage gear 5 has a helical gear at one end and a spur gear at the other end. The second-stage gear 6 and the third-stage gear 7 both have a large gear at one end and a small gear at the other end, and the large gear and the small gear mesh together.

[0029] When motor 3 runs, its output drives the drive gear 4 to rotate. The drive gear 4 drives the first gear 5, the second gear 6, and the third gear 7 in sequence, so that the third gear 7 meshes with the transmission rack 8, causing the rack 8 to slide. The locking rod 10, the locking plate 9, and the rack 8 are integrally injection molded. Therefore, when the rack 8 moves, the locking plate 9 drives the locking rod 10 to extend and retract. The sealing ring 11 prevents dust and other impurities from entering the housing assembly along with the locking rod 10.

[0030] Motor 3 is electrically connected to PCBA12, and PCBA12 controls the operation of motor 3. Micro switch 13 and connector 14 are both fixedly mounted on PCBA12 and electrically connected to PCBA12. Connector 14 is connected to the power supply. Lock plate 9 slides and presses micro switch 13 to trigger micro switch 13 and indicate the locking status of electronic lock.

[0031] When the electronic lock loses power or the circuit malfunctions, the motor 3 cannot be controlled to run, making it inconvenient to unlock. At this time, manually press the emergency lever 16, which will compress the spring 18 and drive the lock block 17 on the side wall to compress the lock plate 9. This will cause the lock plate 9 to drive the lock rod 10 to unlock, thus unlocking the electronic lock. When the emergency lever 16 is released, the spring 18 will compress the emergency lever 16, causing the emergency lever 16 to reset.

[0032] The working principle of the electronic lock provided by this utility model is as follows:

[0033] Motor 3 controls the operation of primary gear 5, secondary gear 6, and tertiary gear 7, which mesh with the transmission rack 8. This causes the locking plate 9 to move the locking rod 10 on the outer casing assembly, thus unlocking or locking the electronic lock. Locking plate 9 will trigger or disengage microswitch 13, generating an indicator signal to facilitate the determination of the electronic lock's unlocked or locked status. In the event of a power outage or circuit failure, the emergency lever 16 can be manually activated to unlock the electronic lock. This electronic lock has both indicator and emergency functions, making it easy to determine the status of the electronic lock and can cope with power outages or circuit damage.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
