Abstract

The utility model relates to a multifunctional cipher lock for a vehicle, which is composed of a digital code disk, a controller and a loudspeaker. The multifunctional cipher lock has the functions of reminding the vehicle starting, preventing the theft and alarming, preventing the vehicle being robbed and reminding the backing alarm. When the multifunctional cipher lock is used, the driver opens an electric door with a key, and the loudspeaker can give out the sound of starting the vehicle after the cipher lock is opened correctly. When the thief steals the vehicle, the electric door is opened by the key and the wrong cipher is input, the cipher lock can cut off the power of an engine, and meanwhile, gives out the alarm sound of catching the thief. When the robber appears, an alarm device can give out an alarm signal only by touching lightly the anti-robbing red key of the digital code disk. When the vehicle runs towards the back direction, a backing blue key is started, and the loudspeaker can give out the sound of the didu-backing. The utility model has the advantages of one object with multiple functions, small size, light weight, easy installation and low cost.

Description

Multifunction cipher lock for vehicle

The utility model relates to a kind of multi-purpose vehicle(MPV) coded lock, especially have drive to inform, the coded lock of burglar alarm, anti-robbing automobile, reversing warning function.

At present, known vehicle cryptographic lock has mechanical type, electronic type coded lock.Mechanical code lock is to adopt dial to connect power switch, do not have the language alarm function, and volume is big, is not easy to install, and cost height, operating safety factor are not high, do not have the anti-robbing automobile function.The electronic type coded lock is made up of keypad and encoder.Because keypad fault rate height is easy to generate error code, simultaneously because the keypad volume is big, is not easy to install, and does not have the function of anti-robbing automobile and reversing warning signal.

The purpose of this utility model provides a kind of multi-purpose vehicle(MPV) coded lock, it adopts the film digital disk, the CMOS integrated circuit, thus volume reduced, reduced weight, reduced cost, improved reliability, be convenient to install, it also has the function of anti-robbing automobile simultaneously, it can be used as backup buzzer and uses during reversing, it have drive to inform, the multiple function of burglar alarm, anti-robbing automobile, reversing warning signal.

The utility model is achieved in that it is made up of encoder, decoder, monostable flipflop, astatic multivibrator, language sheet, power amplifier piece.Its operating principle is that film digital disk Z, password block MK form encoder, and ic chip 1, ic chip 2, exclusion 6R form decoder; Ic chip 3, ic chip 4 are respectively monostable flipflop, and its pin that resets 4 is controlled by pin 13 high level of ic chip 2; Ic chip 5 is the language sheet, and it can provide " driving ", " catch a thief! ", the speech signal of " toot-reversing of ticking "; Ic chip 6 is an audio power amplifying circuit; Ic chip 7 is a self-excited oscillator.During work, 1. termination energize, the pin 3 of ic chip 1, pin 7, pin 11, pin 15 connect high level, and pin 4 is a high level, and pin 5 also connects high level, and its pin 13 is output as low level, and pin 9 outputs also be low level, and pin 10, pin 1 also are low level equally; At this moment the pin 2 of ic chip 2, pin 3, pin 4, pin 5 are input as low level, and pin 1 is output as low level, and triode BG ends, and relay J is failure to actuate, and 2. hold the access failure power supply.Ic chip 2 pin 13 output high level reset the pin 4 of ic chip 3, ic chip 4.

When 12 film digital disk Z correctly input password, make the

3,7,11,15 of ic chip 1 be low level by connector assembly CH and cryptographic block MK, the

13,9,10,1 of ic chip 1 is a high level, the pin 1 output high level of ic chip 2, triode BG conducting, relay J adhesive, 2. termination energize; The self-excited oscillator work of ic chip 7 compositions simultaneously, the pin 10 of triggering language sheet IC5, the voice signal that IC5 produces make loudspeaker send " driving " sound through ic chip 6 power amplifications.

When at 12 film digital disk Z input error codes, make

13,9,10,1 output of ic chip 1 that low level be arranged by connector assembly CH and the cryptographic block MK that set, pin 1 output low level of ic chip 2, triode BG ends, not adhesive of relay J, 2. end-grain cutting outage source; The pin 2 of ic chip 3 has error code ground connection because of cryptographic block MK, and triggered by negative pulse, and its pin 3 output high level, the pin 9 of triggering language sheet IC5, the voice signal that IC5 produces send loudspeaker and " catch a thief through ic chip 6 power amplifications! " sound.

When the robber, the driver presses anti-the misfortune and is good for, and the pin 2 of ic chip 4 is triggered by negative pulse, its pin 3 output high level, and the pin 9 of triggering language sheet IC5, the voice signal that IC5 produces sends loudspeaker and " catches a thief through ic chip 6 power amplifications! " sound.

When needs are moveed backward, press reversing switch, trigger the pin 6 of language sheet IC5, the voice signal that IC5 produces makes loudspeaker send " toot-reversing of ticking " sound through ic chip 6 power amplifications.

Owing to adopt such scheme, can finish reliably drive to inform, the function of burglar alarm, anti-robbing automobile, reversing warning signal.Realize one-object-many-purposes, selected the film digital disk in the circuit for use, the CMOS integrated circuit, simple in structure, cost price is cheap.
