Abstract
The invention relates to door locks, and particularly relates to a sensing type door lock. The invention provides a capacitance type sensing starting door lock which adopts handle sensing due to the fact that the door opening intention of a person can be most really revealed only when the hand of the person is contacted with the handle of the door lock. The door lock comprises a handle, a power supply, a main control circuit and a lock cylinder, wherein the main control circuit is connected with the lock cylinder; the power supply is connected with the main control circuit; a capacitance type sensing triggering circuit connected with the main control circuit is arranged on the handle; a driving motor and a clutch are arranged between the main control circuit and the lock cylinder; and the driving motor is connected with the power supply at the same time. The door lock adopts the handle sensing due to the fact that the door opening intention of the person can be most really revealed only when the hand of the person is contacted with the handle of the door lock; the action of opening the door is most approximate, thereby reducing the false triggering caused by environmental factors; the door lock is more stable than that of the conventional design; and electricity is saved; as the capacitance sensing of the handle is changed while the hand of the person is contacted with the handle; and a signal which can trigger other circuits to work is generated if the change is detected by a capacitance sensing circuit.
Description
Technical field
The present invention relates to a kind of door lock, specifically, relate to a kind of induction type door lock.
Background technology
In the present electronic lock, need battery to work long hours,, only when needs open the door, just get into duty at once so generally adopt power down mode.This just needs a kind of electronic lock gets into duty from power down mode induction that triggers.Thereby can begin to swipe the card, the action of opening the door such as fingerprint typing.Traditional practice is with infrared mode, and when objects such as hand or contactless card were approaching, the external triggering electronic lock of reflect red, but infraredly disturbed easily all can false triggering under the situation that light changes, thereby causes unnecessary power consumption.
Summary of the invention
The present invention overcomes above-mentioned defective, and a kind of employing handle induction is provided, because have only when staff contacts the handle of door lock, could react the induction type door lock of people's the intention of opening the door the most really.
The technical scheme of induction type door lock of the present invention is such; It comprises handle, power supply, governor circuit, lock core; Governor circuit is connected with lock core, and power supply is connected with governor circuit, be provided with on the handle with governor circuit on the capacitive sensing circuits for triggering that are connected; Drive motors and clutch are set between governor circuit and the lock core, and drive motors is connected with power supply simultaneously.
The capacitive sensing circuits for triggering comprise and are fixed on sheet metal on the handle, and sheet metal is connected with the capacitive sensing circuit through linkage, and the capacitive sensing circuit while is connected with governor circuit, power supply.
Induction type door lock of the present invention has advantage:
The present invention is provided with drive motors and clutch to the capacitive sensing circuits for triggering that are connected on last setting and the governor circuit between governor circuit and the lock core, drive motors is connected with power supply simultaneously; The capacitive sensing circuits for triggering comprise and are fixed on sheet metal on the handle, and sheet metal is connected with the capacitive sensing circuit through linkage, and the capacitive sensing circuit while is connected with governor circuit, power supply; The invention provides a kind of induction mode of novel stabilising; Trigger electronic lock and get into duty, adopt special mode that handle is connected with capacitive sensing circuit on the circuit board, when the people will open the door from power down mode; When hand contacts the metalwork of handle; The capacitive sensing circuit inductance that is connected to circuit board arrives, and produces enabling signal, makes other circuit get into duty.
Description of drawings
Fig. 1 is the block diagram of induction type door lock of the present invention.
The specific embodiment
It comprises handle, power supply, governor circuit, lock core induction type door lock of the present invention; Governor circuit is connected with lock core; Power supply is connected with governor circuit; Be provided with on the handle with governor circuit on the capacitive sensing circuits for triggering that are connected, drive motors and clutch are set between governor circuit and the lock core, the drive motors while is connected with power supply.The capacitive sensing circuits for triggering comprise and are fixed on sheet metal on the handle, and sheet metal is connected with the capacitive sensing circuit through linkage, and the capacitive sensing circuit while is connected with governor circuit, power supply.
The present invention adopts the handle induction, because have only when staff contacts the handle of door lock, could react people's the intention of opening the door the most really, the most approaching action of opening the door, thus reduced the false triggering that causes because of environmental factor, more stable than traditional design, more can power saving.Behind staff contact handle, the capacitive sensing of handle is changed, detected the back by the capacitive sensing circuit and produce a signal that triggers other circuit workings.
