Description
Technical field
The present invention relates to antitheft lock technical field, and in particular to a kind of high stability hotel door latch structure.
Background technology
Because traditional mechanical lock is opened with key, so lock body must have hole, and since ancient times, lockset can use
One quota instrument and skill are opened easily, especially the world today, and various advanced unlocking tools emerge in an endless stream, unlocking technique
It is extremely more miraculous.Existing electronic lock realizes and opened that its structure includes shell, front door handle, sets finger on shell using fingerprint
Line acquiring and identifying module and the lock core control device being connected on fingerprint acquiring and identifying module.Have using unlocked by fingerprint convenient easy
The characteristic of operation, still, in operation, human body institute static electrification easily acts on Fingerprint Lock, and its stability is impacted.
The content of the invention
In order to solve the above-mentioned technical problem the present invention provides a kind of high stability hotel door latch structure.
The present invention is achieved through the following technical solutions：
High stability hotel door latch structure, including shell, the front door handle laterally set, fingerprint acquiring and identifying module,
The lock core control device that is connected on fingerprint acquiring and identifying module and the power circuit that power supply is provided for lock core control device, it is described
Signal is connected with drive circuit and drives the drive motor of lock core action successively in lock core control device, it is characterised in that described
Electrostatic discharge protection circuit is connected between power circuit and lock core control device.This programme changes on the basis of existing structure
Enter, i.e., electrostatic discharge protection circuit is connected between power circuit and lock core control device, using electrostatic discharge protection circuit static electricity discharge, carry
The stability of high door latch structure.
Preferably, the electrostatic discharge protection circuit includes diode D1 and diode D2, described diode D1 anode
It is connected on diode D2 negative electrode, described diode D1 negative electrode is connected on power supply, described diode D2 anode
Ground connection, described diode D1 negative electrode are connected on triode T1 colelctor electrode, and described triode T1 base stage passes through electricity
Resistance R1 is connected to emitter stage and grounded emitter, and described diode D1 anode is connected to triode T2 simultaneously by resistance R2
Base stage and triode T3 base stage on, described triode T2 emitter stage is connected on power supply, described triode T2's
Colelctor electrode is connected on triode T3 colelctor electrode, described triode T3 grounded emitter, described triode T3 and three
Pole pipe T1 is NPN type triode, and described triode T2 is PNP type triode.Using two-stage electrostatic leakage and can be according to quiet
Electricity electrically provides a plurality of electrostatic leakage path, effectively that electrostatic leakage is complete, and effectively lock core control device is protected,
Ensure the reliability of lock core control device.
Further, the triode T2 and triode T1 are with model triode.
Further, in order to improve the reliability of circuit, the resistance of the resistance R2 is 200 ohm to 500 ohm.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention utilizes electrostatic discharge protection circuit static electricity discharge, improves the stability of door latch structure.
