Detailed ways

The invention provides an intelligent door lock, which can improve the convenience of maintenance and the convenience of users.

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in Figures 1 to 16, the embodiment of the present invention provides a smart door lock, which can not only realize electronic unlocking, but also can realize mechanical key unlocking, and its related components mainly include front panel assembly 1, lock body 2, controller 3, lock cylinder 4 and rear panel assembly 5, wherein the front panel assembly 1 is one of the appearance parts of the smart door lock, which is arranged on the outer surface of the door 41 to be mainly used for unlocking, and the outer surface refers to What is more is that the door 41 is positioned at the outdoor surface when it is in the closed state; the lock body 2 is an actuator for locking and unlocking, and its main components are dead bolts and electromechanical devices that drive the dead bolts to expand and contract. The lock body 2 is located inside the door 41 (that is, between the outer surface and the inner surface of the door 41); the controller 3 is a single working unit integrated by multiple electronic devices, which is an electronic part of the smart door lock , used to realize functions such as human-computer interaction, information collection, information storage, information display, data communication, and information identification. When the controller 3 is set on the front panel assembly 1, it can be accessed by the user so that the user can disassemble it. When the controller 3 is removed from the front panel assembly 1, it is a separate working unit. 3. The stability and safety of other parts of the intelligent door lock will not be affected, and the function of closing and locking the door and opening the door with a mechanical key can still be completed normally. When the controller 3 is installed on the front panel assembly, it cooperates with other components of the smart door lock, that is, the controller 3 installed on the front panel assembly 1 communicates with the circuit of the front panel assembly 1 to cooperate with the smart door lock. Complete the required related operations; the lock core 4 is arranged on the front panel assembly 1 or the lock body 2, which is the main part to realize the unlocking of the mechanical key. When the user inserts the key into the lock core 4 and turns the key, the lock core 4 It is also possible to drive the deadbolt to expand and contract in the form of mechanical transmission, or to close the clutch of the smart door lock, press the handle on the door to drive the deadbolt to expand and contract, and the lock cylinder 4 and the controller 3 can independently control the unlocking, that is to say, When the lock cylinder 4 does not participate, the controller 3 can independently control the unlocking, and this process is electronic unlocking. Similarly, when the controller 3 does not participate, the lock cylinder 4 that cooperates with the key can also independently control the unlocking , this process is the mechanical key unlocking.

For the smart door lock with the above structure, since the controller 3 as the electronic part of the smart door lock is detachably arranged and exposed on the front panel assembly 1, that is, the controller 3 is set as a working unit that can exist independently and work independently, so when When the controller 3 breaks down, professional maintenance personnel do not need to come to the door 41 for maintenance. The user only needs to successively remove the battery cover 34, a section of the battery 33 and the second connecting piece 28 to remove the controller 3 from the door. 41, and sent to the manufacturer for maintenance, so that the entire smart door lock does not need to be removed from the door 41, the whole process can be realized more autonomously, conveniently and time-saving, and after the controller 3 is removed, the smart The door lock can be converted into a mechanical door lock, that is, the remaining parts after the controller 3 is disassembled (mainly referring to the front panel assembly 1, the rear panel assembly 5, the lock body 2 and the lock cylinder 4, etc.) can also be unlocked by using a key. The stability and safety of the structure are not affected, so there is no need to install and use a spare lock, which is convenient for users. Therefore, the present application can significantly improve the convenience of maintenance and user's use of the smart door lock, and ensure the quality and sustainability of after-sales service.
