Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1 to 5, an intelligent door lock with an anti-following function includes a lock body, a handle assembly, a detection circuit module 4, an MCU controller 5 and a power module, wherein the power module supplies power to the detection circuit module 4 and the MCU controller 5, and the handle assembly is used for controlling the lock body to be closed or opened;

be equipped with magnet steel 3 in the handle subassembly, magnet steel 3 rotates along with the handle subassembly, detection circuit module 4 detects magnet steel 3's position and will detect signal transmission for MCU controller 5. When a user presses down the handle body 1, the handle reversing disc 2 and the handle body 1 rotate coaxially, the detection circuit module 4 detects that the magnetic steel 3 deviates and sends a high level signal to the MCU controller 5, the MCU controller 5 starts to time, and continuously receives the high level signal within a set certain short time, and the MCU controller 5 sends a signal to control the lock body to be locked; when the user does not pull down the door handle, detection circuit module 4 detects that magnet steel 3 is close to, sends low level signal to MCU controller 5, and in setting for a certain period of time, level signal does not take place to change, and MCU controller 5 sends the signal control lock body and locks.

The handle assembly comprises a handle base, a handle body 1 and a handle reversing disc 2 are arranged on the base, the handle body 1 and the handle reversing disc 2 are respectively arranged on two sides of the base, the handle drives the handle reversing disc 2 to rotate, magnetic steel 3 is fixed on the outer wall of the handle reversing disc 2 and coaxially rotates with the handle reversing disc 2, a detection circuit module 4 is fixed on one side of the base, provided with the handle reversing disc 2, and the detection circuit module 4 is arranged right above the initial position of the magnetic steel 3.

The detection circuit module 4 comprises a Hall sensor and a filter circuit, and the signal output end of the Hall sensor is connected with the filter circuit and then connected with the MCU controller 5. The filter circuit is an RC filter circuit formed by a resistor R1 and a capacitor C1. The Hall sensor is an integrated chip and has the function of exciting a magnetic field of a full magnetic pole (namely, not dividing an S pole or an N pole); when the magnet approaches the Hall sensor, the signal output end of the Hall sensor outputs a low level; when the magnet is far away from the Hall sensor, the signal output end of the Hall sensor outputs high level, and the stable return difference ensures the stable state of the sensor switch. The resistor R1 and the capacitor C1 function as a filter to ensure that the signal is not distorted by external interference.
