Abstract

The utility model relates to an electronic built-in lock and a key which is matched with the lock to use, wherein, a lock body (also called a receiver) of the electronic built-in lock is composed of a receiving circuit, a demoding circuit and an output driving circuit, and the operating voltage is provided by the same direct current source. The key (called emitter) which is matched with the built-in lock to use is composed of a coding circuit and a transmitting circuit which is connected with the coding circuit, the operating voltages of the coding circuit and the transmitting circuit are provided by the same direct current source. The design has the advantages that the structure is artful; the lock body is hidden, so the anti-theft coefficient is high, and robbers are not easy to remove and damage.

Description

The stealthy lock of electronics

The utility model relates to a kind of theftproof lock technical field.

Mechanical lock is already by people's understanding and generally use in the prior art, its principle is similar, for theft-prevention structure also becomes increasingly complex, but also be unable to escape the ability of taking off thief's picking lock, because being it, the fatal shortcoming of this lock all is mounted in the showy place of people, that is to say that whatsoever the position all can be found by the people, so also just be easy to be tried every possible means to open by the people.In addition, in order to remedy mechanical lock safe antitheft function, at present society go up most popular a kind of anti-theft measure be install toot cry or alarm, and alarm also has its weakness, promptly produce noise, contaminated environment, because pedestrian or child mistake is hit, and usually cause false alarm again; It also reminds the robber need take what measure in addition, makes it malfunctioning.

The purpose of this utility model provides the stealthy lock of a kind of electronics, and is when mounted hidden, also has key with matching simultaneously, and they and mechanical lock are used, for mechanical lock increases the locking anti-theft wire one.

This purpose realizes with following technical proposal: the stealthy lock of this electronics, the lock body that it is made of circuit board and shell, promptly be called receiver, this receiver is mainly by receiving circuit, connect a decoding circuit in its output, and the output of decoding circuit is connected with the output driving circuit formation, and they are connected on the same power supply.The key of the stealthy lock of unlocking electronic, the key body that it is made of circuit board and shell promptly is called transmitter, and this transmitter connects a radiating circuit in its output and constitutes mainly by coding circuit, provides operating voltage respectively by same power supply.

The utility model structure is ingenious, installs hiddenly, operates also hiddenly, is not found by the people, so difficulty or ease are destroyed; It uses on vehicle or other utensil, and the robber opens mechanical lock, also can't start antitheft thing, because stealthy lock is not also opened; Again because of cannot see the residing position of stealthy lock, so the robber can't set about.Then improved safety factor greatly.

Following accompanying drawing has provided embodiment of the present utility model:

Fig. 1 is the circuit block diagram of the stealthy lock of electronics.

Fig. 2 is the circuit block diagram of the key of the stealthy lock of unlocking electronic.

Fig. 3 is the circuit working schematic diagram of the stealthy lock of electronics.

Fig. 4 is the circuit working schematic diagram of key.

In conjunction with the accompanying drawings stealthy lock of this electronics and key thereof are made a detailed description:

Shown in Fig. 1,3, the steady shape of this electronics lock mainly by receiving circuit 1, be connected to decoding circuit 2 in the output of receiving circuit 1, be connected with output driving circuit 3 in the output of decoding circuit 2 and constituted, power circuit 4 provides operating voltage respectively to the above circuit.Referring to Fig. 3, described receiving circuit is by ic chip ₁Constitute, specifically get HS201 electromagnetic wave receiver module, its receive frequency is 280MHz, operating voltage is the 6V DC voltage, include circuit such as high frequency reception, amplification, demodulation, shaping in this module, its output signal is to export decoding circuit 2 to by 3 pin, and decoding circuit is mainly by IC ₂Integrated package constitutes, and gets typical VD5027 decoding circuit module here, and after the VD5027 decoding, its 17 pin output high level is given drive circuit 3, at first goes control relay K adhesive after the VT amplifying triode amplifies, and finishes unlocking function.

As shown in Figure 2: the key of the stealthy lock of this unlocking electronic mainly is by coding circuit 5, constitutes at its output connection one radiating circuit 6.Provide operating voltage to them respectively by dc source 7.Referring to shown in Figure 4, coding circuit mainly is by IC ₃Integrated package constitutes, and gets VD5026 and forms typical coding circuit, and coding back signal is by IC ₃17 pin export IC to ₄Radiating circuit, radiating circuit are got HS101 Electromagnetic Launching module and are constituted, and its frequency is 280MH _z, operating voltage is in 1.5～18V.

Here it is to be noted coding circuit module and decoding circuit module when selecting for use, the S of the two combination is corresponding one by one mutually, capacitor C wherein ₁=C ₃, resistance R ₁=R ₄This stealth is locked in a suitable receiver when using, key is a transmitter with respect to lock, when transmitter quits work or does not receive signal because of distance receiver far away, the 17 pin output low levels of decoding circuit VD5027, relay discharges, and promptly stealthy lock is in locking, and what join with it is driven the circuit cisco unity malfunction.

Physical circuit in the enforcement such scheme has multiple, and for example the radiating circuit in the transmitter also can adopt ultrasonic emitting etc. except that radio transmission, and recipient also just has corresponding receiving circuit part so; Coding circuit is gone back the usable frequency assembly coding except that digital assembly coding; Drive circuit removes relay and drives, and also can adopt the non-contact type on-off circuit to drive.

Use illustrates:

For example be used for motorcycle anti-theft, at first the stealth lock be loaded on the hidden place of motorcycle, from not found in appearance by the people, (being contained in lampshade or fuel tank bottom etc.), when lock body was not received signal, stealthy lock was in closed condition, and control motorcycle ignition circuit cisco unity malfunction; When lock body was received signal, promptly stealthy lock was in open mode, and motorcycle also is in normal operating conditions.This is to utilize static contact short circuit of relay or open circuit and trigger ignition coil on the car according to drive circuit in the present embodiment.

Usually the electric switch key and the stealthy lock key of motorcycle are together carried, when using car, when taking the electric switch key, open stealthy lock key (being transmitter), at this moment entered within the remote control distance, and the stealthy signal of receiving the key emission of locking is opened automatically, after the electricity consumption door key was opened car door, car can be handled walking immediately.During without car, close electric door lock, in discharge door lock key, smoothly the stealthy lock key in the bag (being transmitter) is closed.

Certainly, this stealth lock also can be used on security door and other utensil, and according to the structure of door lock, then its driven object also will change.
