A safe and stable intelligent door lock with switching function and dual power supply

Abstract

The invention relates to a safe and stable intelligent door lock adopting two power supplies and having a switching function. The safe and stable intelligent door lock comprises a main body; a handle,a rotating shaft, a clamping plate, a fingerprint window and a touch screen are arranged on the front surface of the main body; a gear, a movable plate, a movement mechanism and two power supply mechanisms are arranged in the main body; each power supply mechanism comprises a battery box, a translation plate, a connecting assembly, two electric conducting rods and two electric conduction assemblies; and the movement mechanism comprises a frame, a movable plate, two sliding plates and two fixing assemblies. When the safe and stable intelligent door lock adopting the dual power supply and having the switching function is in use, any one power supply mechanism can be selected by the clamping plate via the movement mechanism to supply power to a touch screen and a fingerprint window, so thatsufficient energy is provided when equipment is required to be used, an owner is prevented from being locked in a room, and the operation is more convenient. In addition, after the handle is rotated,power supply assemblies can automatically cut off the power of the touch screen and the fingerprint window, so that the power-on time is shortened, the cruising power is strengthened, and the practicability of the equipment is improved.

Description

Technical field [0001] The invention relates to the field of smart locks, in particular to a safe and stable smart door lock with a switching function and adopting dual power supplies. Background technique [0002] Smart door lock refers to a lock that is improved on the basis of different from traditional mechanical locks, and is more intelligent and convenient in terms of user safety, identification and management. The smart door lock is the executive part of the door lock in the access control system. [0003] In the existing smart door locks, a single power supply is usually used to supply power to the locked touch screen and fingerprint window. When the power in the power supply is exhausted, if the owner does not replace the battery in time, the owner will easily be locked out of the door at this time. It is impossible to open the door to enter the room. Not only that, because the touch screen and fingerprint window in the door lock are always energized, the device has been ...

Problems solved by technology

[0003] Inside the existing smart door lock, a single power supply is usually used to supply power to the locked touch screen and fingerprint window. When the power in the power supply is exhausted, if the owner fails to replace the battery in time, the owner is easily locked out of the door. Unable to open the door to enter the room, not only that, because the touch screen and fingerprint window in the door lock are always powered on, so that the device has been consuming power in the power supply, which in turn shortens the service life of the power supply and weakens the battery life of the device capability, thereby reducing the practicality of existing smart locks
