Description

Electric lockset triggered and controlled by door handle rotation

Technical Field

The invention relates to a lockset for a household door leaf, in particular to the field of electric locksets. The electric lockset adopts identification technologies such as fingerprints, passwords, human faces and the like to form an electric signal for allowing the door to be opened on the basis of the traditional mechanical lockset, and controls the opening or closing action of a handle clutch of a lock body, thereby assisting the door handle to realize the opening or locking of the door. Another improved full-automatic electric lock in recent years is based on biological signal identification or password and magnetic card door opening signal identification, and starts to install an electric driver in the lock body or the lock panel to directly drive the bolt to extend or retract, and the lock or the unlock can be directly and fully automatically completed without the action of an outer door handle or an inner door handle.

Background

The existing electric lock, whether traditional or newly improved, includes inner and outer panels, a lock body, a controller, etc. Conventional locks also typically include a door handle for unlocking the lock and pushing the door leaf. The newly developed full-automatic electric locks can rely on an electric driver for unlocking and locking, so that a door handle is omitted, and a door handle is replaced by the door handle, the door handle is only used for providing an operation part for a user to push a door, and at least the door handle is not combined with the lock body in a logically moving association for opening and closing the door. For the full-automatic electric lock, the door can be directly unlocked by inputting a door opening instruction when the door is opened outwards, and the lock body is automatically locked by induction after the door leaf is closed after the unlocking is finished; when the door is opened in the door, the door opening button can be directly pressed to unlock the door, and after the door is closed, the lock body is automatically locked in an induction mode. However, for a fully automatic electric lock, the door leaf is closed to complete locking control, and generally, a locking instruction is obtained by sensing the position of the door leaf to complete locking; the sensing of the door leaf position generally includes infrared sensing, gyroscope detector sensing, or geomagnetic sensor sensing. Although the infrared sensing method is relatively stable, since the infrared sensing method requires an infrared transceiver to be installed on the door leaf and the corresponding door frame, the manufacturing cost and the installation cost are high; although the installation and manufacturing costs of the gyroscope detector sensing or the geomagnetic sensor sensing are relatively low, the stability is very poor, and the door closing data of the door leaf is easy to drift. Therefore, for a fully automatic lock adopting a gyroscope sensor sensing mode or a geomagnetic sensor sensing mode, it is very important to effectively reduce the drift of door leaf position data. For example, the invention patent application No. 201910298364.5 entitled "door-behavior-state-based lock control method", discloses a door-behavior-state-based lock control method, which is characterized by picking up characteristic values including an angular velocity change characteristic value provided by a rate gyro detector when the door moves and an acceleration change characteristic value provided by an acceleration sensor when the door moves, in order to overcome the drift characteristics of the gyro detector and the negative effects of drift or misjudgment caused by external noise (e.g., door kicking, building vibration); setting an attitude fusion calculation model, and obtaining an attitude characteristic data table for representing the behavior state of the door leaf based on the calculation model according to the picked characteristic values; the data tables comprise an initial attitude data table and a current attitude data table, and the data tables comprise a closed position data table, a door closing vibration data table and a door closing movement data table based on different states of door leaf behaviors; in the standard movement of one door leaf, obtaining an initial attitude data table based on the calculation model according to the picked characteristic value of the standard movement and calibrating the initial attitude data table as a coordinate origin; in the current movement of the door leaf, a current attitude data table is obtained according to the picked current characteristic value of the current movement based on the calculation model; and the controller analyzes the door leaf state according to the current attitude data table in different states continuously obtained in the current movement of the door leaf, and examines the position of the current attitude data table on the coordinate to implement corresponding locking control. The technical scheme adopts a three-layer judgment method to select whether to send a locking instruction, namely the first layer mainly judges whether a door leaf accords with a correct locking position and selects whether to send the locking instruction based on a closed position current attitude data table; the second layer is mainly used for judging whether the door leaf accords with the correct locking position and selecting whether to supplement to send a locking instruction or not based on the door closing vibration current attitude data table after the first layer fails; when the first layer and the second layer are judged to be out of order, the third layer is started finally, namely, the forced locking instruction is notified to be started manually through means such as alarm prompt and the like to control locking.

As shown in fig. 3, the sensor further comprises a signal trigger 5 and at least two signal detection parts arranged at intervals, namely a first signal detection part 61 and a second signal detection part 62, wherein the signal trigger 5 is a magnet, and the signal detection parts are hall elements. The first signal detection piece 61 and the second signal detection piece 62 are arranged on the plate body 7 at a fixed position at one non-rotatable side defined by the inner panel 2 at intervals, and the plate body 7 is positioned at the inner side of the inner panel 2 through screws; the inner side end of the inner door handle 21 is provided with a rotating disc 8 which can rotate along with the inner door handle 21, the rotating disc 8 is collected in the inner space of the inner panel 2 and is positioned between the inner panel 2 and the plate body 7, and the signal trigger piece 5 is arranged on the rotating disc 8, wherein the rotating disc 8 belongs to one of the rotatable one-side rotating positions defined by the inner door handle 21.

The one-side rotation position defined by the inner door handle 21 means a position, including the inner door handle 21, on one side of the inner door handle 21, which can rotate and move and is relatively rotatable or movable with respect to the door leaf or the inner panel 2, and includes the inner door handle 21 itself, a turntable mounted on the inner door handle 21, and other members. For this purpose, the signal triggering element 5 can be arranged not only on the inner door handle, but also on other components, such as a rotary disc, which can be displaced on the side defined by the inner door handle 21.

The non-rotatable side fixing position defined by the inner panel 2 refers to a fixing position which is located on one side of the inner panel 2, including the inner panel 2, is not rotated or moved and is fixedly installed and positioned relative to the door leaf, and includes the inner panel 2 itself and other components installed on the inner panel 2 or the door leaf.

That is, if the door is not closed for a long time after the manual door opening, the control unit 9 sends out a warning signal such as an alarm. The preset time refers to a standard action time set in a program before the equipment leaves a factory, and the time can be determined according to the actual environment condition, for example, 10 seconds, 60 seconds and the like, for this reason, the method can give an alarm and the like by means of the trigger signal transmitted by the first signal detection piece 61 if the equipment is not locked in time, and the use safety of the intelligent door lock is greatly improved on the basis of improving the accuracy.

In order to pick up one or several of the above signals, one or several different signal sensors may be provided, wherein common signal sensors include a rate gyro detector detecting a signal of angular velocity change, an acceleration sensor detecting a change in acceleration, a magnetometer detecting a signal of direction of motion, and the like.

The current characteristic value is a corresponding characteristic value corresponding to a signal picked up by the current door closing action or the door opening action.

The reference characteristic value is a corresponding characteristic value of a signal picked up by a standard door opening or closing action performed during installation and debugging; or in daily use of the door leaf, the control unit 9 automatically memorizes the characteristic value corresponding to the door opening and closing action which is already completed and confirmed to be successful, and replaces the previous characteristic value to generate a new characteristic value, and the new characteristic value is used as a reference characteristic value when the door is opened next time.
