Description

Electronic lock with anti-lock function

The invention relates to an electronic lock, in particular to an electronic lock with an anti-lock function capable of selectively stopping the action of the motor and thereby locking the gate.

In addition to the locks that are normally opened with a key, there is also an electronic lock that is the switch interface of the front panel that receives the access card, fingerprint recognition or presses the switch code input by the keyboard to open or close the door. The benefits of the electronic lock The small size of the access card is easy to store and carry, and even when the lock is unlocked, the access card is not needed. Just extend the finger to let the electronic lock recognize or press the keyboard to input the switch code.

Although the existing electronic lock has the advantage of convenient unlocking, since the general electronic lock can only be designed to open or close the door by the switch interface of the front panel, the motor cannot be controlled behind the electronic lock, so the person in the gate needs When the door is locked and not disturbed, in addition to locking the door with other bolts, the anti-theft chain provided on the inner side of the door can only be buckled, and the electronic lock cannot be changed to the anti-lock state without being opened from the outside.

Since the existing electronic lock lacks the anti-lock function, it is very troublesome for the user to need to additionally set the door latch or the anti-theft chain when the door is locked. To this end, the present invention is provided with an anti-locking kit in the electronic lock to control the motor to operate without locking to achieve the effect of locking the electronic lock after closing the door.

To achieve the above object, the present invention provides an electronic lock with an anti-lock function, comprising:

a controller electrically connected to a motor drive circuit;

An electronically controlled latch structure having a motor for driving a latch to be in an open state or a closed state, the motor being electrically coupled to the motor drive circuit;

An anti-locking kit, a switch module is connected in series between the motor and the motor drive circuit, and an anti-lock interface is provided, and the switch module is controlled to be a path or an open circuit by the anti-lock interface.

Further, the present invention is provided with a front panel on which a switch interface is provided, the switch interface being electrically connected to the controller.

Furthermore, the present invention is provided with a rear panel, and the anti-locking interface is disposed on the rear panel.

When the invention is used, it is disposed at the gate, and the latch constructed by the electronically controlled latch locks the gate or changes the gate to an openable state. When the user closes the door and closes the latch, if there is a need to lock the electronic lock, the anti-lock interface controls the switch module to be in an open state. Since the motor and the motor drive circuit are disconnected at this time, Even if someone takes the correct access card or enters the correct switch code into the electronic lock, the controller control motor will not open the latch.

The utility model has the advantages that the setting of the anti-locking kit enables the user to actually lock the electronic lock by stopping the action of the motor, and can be made before the state in which the user does not open the switch module to the state of the passage. The door is kept in an anti-lock state, which prevents the user from being disturbed by the opening of the door by others, and even blocks the gangster who wants to break the electronic lock into the house, and the electronic lock itself has an anti-lock function, and the user does not need another Set the anti-theft chain, easy to use and increase the added value of the electronic lock.

In order to understand the technical features and practical effects of the present invention in detail, it can be implemented in accordance with the contents of the specification, and further described in detail with reference to the preferred embodiments shown in the drawings.

As shown in FIG. 1 to FIG. 3, the present invention is an electronic lock with an anti-lock function, comprising a front panel 10, a rear panel 20, a controller 30, and an electronically controlled latch structure 40 electrically connected to the controller 30. And an anti-locking kit 50 electrically coupled between the controller 30 and the electronically controlled latch structure 40, wherein:

The front panel 10 is disposed opposite to the front panel 20 for mounting on the outer side of the gate. A switch interface 11 is disposed on the surface of the front panel 10. The switch interface 11 can be a contactless card reader and contact. a card reader, a fingerprint reader, an iris recognizer or a keyboard. In the preferred embodiment, the switch interface 11 is a contactless card reader; the rear panel 20 is oppositely disposed behind the front panel 10. It is used to mount on the inside of the gate.

The controller 30 is a microcontroller that integrates a central processing unit, a random access memory, a read-only memory, an input/output, a digital/analog conversion function, and the like, and can perform arithmetic processing, memory storage, input/output, and the like. Controlling, the controller 30 is disposed in the front panel 10 and electrically connected to the switch interface 11. When the switch interface 11 receives the switch code of the access control input, the switch code is input to the controller 30. The controller 30 is electrically connected to a motor drive circuit 31.

The electric control latch structure 40 is provided with a motor 41. The motor 41 is coupled to and drives a latch 42 to be in an open state or a closed state. The motor 41 of the electronically controlled latch structure 40 is electrically connected to the motor drive circuit 31 of the controller 30. When the controller 30 receives the switch code input from the switch interface 11, the motor drive circuit 31 is caused to control the motor 41 to drive the latch 42 to the open state or the closed state.

The anti-locking kit 50 is a switch module 51 connected between the motor 41 and the motor driving circuit 31. The switch module 51 can be a mechanical switch or a mechanical switch. The anti-locking interface 52 is provided with an anti-locking interface 52 on the surface of the rear panel 20, and the anti-locking interface 52 can be a button or a touchpad. As in the preferred embodiment, the anti-locking interface 52 is provided. The anti-lock interface 52 is electrically connected to the switch module 51 to control the switch module 51 to be a path or an open circuit. The anti-lock interface 52 can be wirelessly connected to the switch module 51. The module is wirelessly connected to the switch module 51, and the function of controlling the switch module 51 to be a path or an open circuit is also achieved.

When the user closes the door provided with the present invention and the door latch 42 of the electronically controlled latch structure 40 is closed, if the electronic lock needs to be locked, the switch module 51 is controlled to be in an open state by the anti-lock interface 52. Even if someone touches the switch interface 11 of the front panel 10 with an access card, since the motor 41 and the motor drive circuit 31 are in an open state, the motor 41 does not operate at this time, and the door latch 42 is not driven to be in an open state. Before the state in which the switch module 51 is disconnected is changed to the state of the path, the gate is kept in an unlocked state by the electronic lock, and the electronic lock cannot be opened from the outside.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the scope of the claims of the present invention, and other equivalent changes or modifications which are not departing from the spirit of the present invention should be included in the present invention.
