Referring to fig. 1-6, the novel electronic lock comprises a handle 1 and a body 2, wherein the front ends of the handle 1 and the body 2 are rotatably connected through a rotating shaft 14, and the novel electronic lock has two states of locking and unlocking; when unlocking, the handle 1 can be opened upwards relative to the body 2 and can rotate left and right; when locked, the handle 1 is downwardly coupled to the body 2 and remains closed.

Wherein, a lock core rotor 3 is rotatably positioned at the rear end of the handle 1, and the rotating shaft of the lock core rotor 3 is arranged along the thickness direction of the handle 1. The upper end of the lock cylinder rotor 3 is provided with a lock hole 4 for inserting a key. A clamping point 5 is convexly arranged on the side part of the lock core rotor 3, and the clamping point 5 changes the circumferential position along with the rotation of the lock core rotor 3; the lower side of the handle 1 is further provided with a hook 6 protruding forwards towards the rotating shaft 14.

An electromagnet 7 is positioned in the body 2, the electromagnet 7 drives a clamping tongue 9 to make linear displacement along the length direction of the body 2 in the front-back direction through a connecting rod 8, and the clamping tongue 9 is formed to have two states of extension and retraction; a permanent magnet 10 is arranged on one side, opposite to the clamping tongue 9, of the shell of the electromagnet 7 and used for keeping the retraction state of the clamping tongue 9; the clamping device also comprises a first spring 11, wherein the first spring 11 is sleeved on the connecting rod 8 to keep the clamping tongue 9 in an extending trend; the magnetic attraction force of the permanent magnet 10 to the clamping tongue 9 is greater than the tension force of the first spring 11.

As shown in fig. 1 and 2, when the latch 9 is in the extended state, the latch 9 is in snap fit with the hook 6 of the handle 1 to form the latch 9 to limit the hook 6, and at this time, the handle 1 cannot be opened, and the handle 1 keeps the locked state.

As shown in fig. 3 and 4, when the latch 9 is in the retracted state, the latch 9 is attracted to the permanent magnet 10 of the electromagnet 7 against the force of the first spring 11, so that the latch 9 yields the hook 6, and the handle 1 is unlocked and opened.

The body 2 is further provided with a reset mechanism, the reset mechanism comprises a reset rod 12 and a trigger switch 13, and the trigger switch 13 can be a microswitch. The reset rod 12 is slidably positioned in the body 2 along the length direction of the body 2, a first end (i.e., the rear end) of the reset rod 12 is arranged corresponding to the side portion of the lock cylinder rotor 3, and a second end (i.e., the front end) is arranged corresponding to the contact 15 of the trigger switch 13; the trigger switch 13 is fixedly arranged in the body 2, electrically connected with the electromagnet 7 and used for sending a trigger signal to the electromagnet 7 to work. The lock cylinder further comprises a second spring 16, wherein the second spring 16 is sleeved on the reset rod 12, so that the reset rod 12 keeps the trend of moving towards the lock cylinder rotor 3.

The first end of the reset rod 12 is connected with a base body 17, and the latch 9 is positioned on the base body 17, so that the latch 9 and the reset rod 12 are linked.

As shown in fig. 5, when the key cylinder rotor 3 is rotated by the operation of the key, the click 5 is circumferentially displaced with the rotation of the key cylinder rotor 3; when the stuck point 5 rotates to contact the first end of the reset rod 12, the stuck point 5 forces the reset rod 12 to displace toward the trigger switch 13 against the force of the second spring 16 by the rotating force, so that the second end of the reset rod 12 contacts the contact 15 of the trigger switch 13.

At this time, if the electronic lock is in the power-on state, the trigger switch 13 triggers the electromagnet 7 to operate, and the latch 9 extends out, so that the handle 1 is kept in the locked state. That is, in the energized state of the electronic lock, the mechanical unlocking cannot be performed directly using the key. The safe cabinet unlocking method has the advantages that only card swiping unlocking can be realized, the monitoring of unlocking information such as ID (identity) of an unlocking person and unlocking time is facilitated, and accordingly reliability and safety of use of the cabinet are guaranteed.

If the electronic lock is in a power-off state, the trigger switch 13 cannot trigger the electromagnet 7 to work, and the clamping tongue 9 retracts along with the displacement of the reset rod 12 and is adsorbed on the permanent magnet 10 of the electromagnet 7, so that the handle 1 is unlocked. That is, in the power-off state of the electronic lock, the mechanical unlocking can be performed by the key. In order to cope with special situations such as power failure, malfunction, etc.

The reset mechanism is used for resetting the clamping tongue 9 to restore the matching state of the clamping tongue 9 and the clamping hook 6; the reset mechanism and the electromagnet 7 are matched to form electromechanical interlocking.

Wherein the electromagnet 7 is a bidirectional electromagnet. When a user sends an unlocking instruction, the electromagnet 7 drives the clamping tongue 9 to retract, the retraction holding time can be set, and the clamping tongue extends out again after a period of time, so that the electronic lock automatically restores the locking state. When a user operates the lock core rotor 3 by using a key to unlock, if the electronic lock is in a power-on state, the electromagnet 7 is triggered to work by the trigger switch 13 and drives the clamping tongue 9 to extend out.

The electronic control part is connected with the body and comprises a signal receiving end and a signal sending end; the signal receiving end receives an unlocking signal, the signal sending end is electrically connected with the signal receiving end and the electromagnet 7 in a wired or wireless mode, and after the signal receiving end obtains the unlocking signal, the signal sending end triggers the electromagnet 7 to work.

Wherein, the signal receiving end is a wireless card reader 18, and a user unlocks by swiping a card.

Or the signal receiving end is connected with an upper computer (such as a PC), and the user sends an unlocking signal to unlock the lock through the upper computer.

The utility model discloses can realize that the backstage is long-range unblanks, the card of punching unblanking (for electric state), mechanical key unblanks (only when electronic lock outage or trouble). The utility model discloses can dispose the authority of unblanking to can have the suggestion of lock state (pilot lamp, bee calling organ etc.).

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
