The electronic door lock of the above structure can achieve the corresponding function. However, it has the following shortcomings: 1. Because the internal handle of the above electronic lock directly drives the mechanical lock to open the door, and the existing security door has a cat's eye, it is easy to pass the lever through the cat's eye and rest on the inside of the hand. The unlocking is achieved by pressing the lever, and the anti-theft performance is not ideal. 2. The clutch of the aforementioned electronic lock is not on the same axis as the inner handle, and the aforementioned electronic lock is prone to unstable transmission. 3. The motor and battery case of the aforementioned electronic door lock are separately arranged, and when one of the components is damaged, the maintenance is very inconvenient.

Summary of the invention

The object of the present invention is to provide an electronic door lock with good anti-theft performance and convenient maintenance.

To achieve the above object, the present invention is achieved by the following technical solutions:

An electronic door lock, the outer casing of the electronic door lock is fixed on the outer side of the door panel, the outer casing is provided with an unlocking information collector, and the outer casing is pivotally connected with an outer handle; the inner casing is fixed on the inner side of the door panel, and the inner casing is pivotally connected There is an internal handle; the mechanical lock is fixed in the door panel, the mechanical lock is provided with a main lock tongue and a shaft hole linked with the main lock tongue; the square shaft drives the main lock tongue through the shaft hole of the mechanical lock; The electronic door lock is provided with a transmission shaft for transmitting the outer handle movement to the inner casing, and the inner casing is provided with a clutch seat, and the transmission shaft is interlocked with the clutch seat through the inner linkage mechanism; the clutch pin with the return spring is disposed in the clutch seat a square shaft seat is provided in the clutch seat, and one end of the square shaft is inserted into the square In the shaft seat, a clutch groove for inserting the clutch pin is arranged in the square shaft seat. When the motor of the electronic lock is unlocked, the motor presses the clutch pin into the clutch groove, the clutch seat rotates the square shaft seat, and the square shaft seat is driven by the square shaft.
