Description

Theft-proof alarm electronic lock for bicycle

The utility model relates to a kind of lockset, particularly a kind of bicycle anti-theft alarm electronic lock.

Current, stolen having become of vehicle (particularly bicycle) upset society, endangers the big public hazards in the people, and be well-known, when stolen situation takes place vehicle, must make vehicle lose static balancing, follows to occur rocking and the material that quivers; And desire to reach when car theft ridden away, need destroy lock.

The purpose of this utility model provides a kind of bicycle anti-theft alarm electronic lock for addressing the above problem exactly.

The purpose of this utility model is achieved in that

The bicycle anti-theft alarm electronic lock is by separating alert and establishing alert cipher control parts, power amplifier, electronic switch, warning language sheet, annular soft locking wire, formations such as button; Wherein,

A. separate the police and establish alert cipher control parts IC ₁Reset terminal connecting resistance R ₀And capacitor C ₀Coupling end, its clock diablement end 13 passes through R respectively ₁₂Meet aerotron VT ₃Base stage and capacitor C _JAn end, button A _JBe connected in parallel on C _JTwo ends; Aerotron VT ₃Collecting electrode sending and receiving optical diode H and resistance R ₁₃IC ₁3,2,4,7 pin meet keyboard A respectively _M1, A _M2, A _M3, A _M4

B. sensing element HG is attempted by switch AC ₁, AC ₂, AC ₃Two ends; Resistance R is passed through in the fixed end of HG ₈The control utmost point, electronic switch that connect controllable silicon SCR in the electronic switch are by SCR and aerotron VT ₁Constitute VT ₁Base stage pass through resistance R ₅Connect the silicon controlled anode, and aerotron VT ₂Collecting electrode, VT ₂Base stage pass through C ₀, button A _M0And resistance R ₁₀Meet IC ₁10 pin;

After the installing component MN of c. annular soft locking wire XY and this machine is connected in series, be connected in parallel on aerotron VT ₄Emitter and base stage between;

D. language sheet IC reports to the police ₃And power discharging IC ₂Constitute the language alarm circuit.

The utility model has following characteristics in design:

(1) is provided with highly sensitive long-life sensing element HG that experiences car body fine motion amount;

(2) be provided with " annular flexible cord " XY as the lock control line,, trigger at once and report to the police in case this line is split off;

(3) for to make each facility be equipped with self independence and confidentiality; the utility model removes warning (contain and do not establish the police) and takes " making multidigit cipher control technology in limited time "; make unique oneself the password of each machine; the decoding rate is extremely low; confidentiality is with extremely strong; the anti-theft alarm function of this machine of making obtains good, perfect protection.

(4) adopt the cipher control parts of the extremely low IC of quiescent dissipation as " separating the police " and " establishing the police ", do not having when police, this machine is in state on duty, and the complete machine minimal power consumption is almost near the natural discharge current of battery.Therefore, generally speaking, this machine self-contained battery can reach more than half a year service life.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1: the utility model circuitry schematic diagram.

Referring to Fig. 1: after the power supply, R ₀And C ₀Produce a positive pulse and add to IC ₁Reset terminal (RESET) 15, make diode D ₀Outwards provide and establish alert power supply.At this moment, be torn if any stealing feelings generation (being that HG connects or annular soft locking wire) XY) will make by SCR and VT ₁The electronic switch that the constitutes conducting that is triggered, alarm voice sheet IC ₃With power amplifier IC ₂Because of getting the electric language alarm sound that sends suitable sound level.Because electronic switch has memory function when design, so alert sound will be continuously, to remove and report to the police by the control in limited time of multidigit password, its operation order is as follows: at first press the AJ key, make IC ₁Clock diablement end 13 be the transient state low level, light-emitting diode H is luminous, indicates this state, (the little illumination of H double as keyboard at night), then must be in the time limit order press Am1, Am2, Am3, Am4 make 10 pin output high level, button Am0 again, trigger triode VT ₂Of short duration conducting makes electronic switch close, and alert sound stops.

The utility model adopts 4 * 3 keyboard operations, and therefore separating alert password is actually a large amount of, unduplicated assembled arrangement sign indicating number.Separate when alert, must by above password in limited time in operation in order.Separate when alert, as at first not pressing AJ, the key operation of AM1-AM4 is invalid with making; As not pressing AM1-AM4 in proper order, will make part operation invalid; During operation, press A01-A03, will former operation be neutralized as mistake; To be touched sound immediately as mistake by the Ac1-Ac3 warning circuit.Hence one can see that, separates alert go out sign indicating number difficult decoding is arranged, and like this, the warning function of this machine improves, and realizes good self-protection.

This machine is established alert operation and is adopted the singly-bound plain code.Be at this machine and separate when not establishing alert state after alert, establish the police, only need press singly-bound As one time, establish the alert merit of promptly accomplishing as desire.

In order further to strengthen the self-protection function, the installing component of this machine, as fixing casing snap ring, bolt of rear end plate etc. are all the assembly that can trigger warning, represent with MN among Fig. 1, in case their are destroyed, dismantle i.e. triggering warning.In addition, because this machine is in outdoor mounted, the housing structure design has water-proof function.

The element model of the utility model embodiment is as follows:

IC ₁: TC4017BP; IC ₂: CM386N-1; IC ₃: LQ46; AJ; As; A ₀₁～A ₀₃AM0～AM4; Touch key in Ac1～Ac3 is equal; H: light-emitting diode; DW: zener diode; The SCR one-way SCR; VT: aerotron.
