Description

Electronic type stepney and storage battery burglar alarm

One. affiliated technical field:

The utility model relates to a kind of electronic type warning device, is particularly suitable for stolen or send the burglar alarm of sound and light alarm signal when losing at automobile spare tire and storage battery.

Two. background technology:

Along with the rapid progress of China's rapid economy development and science and technology, automobile is also more and more come into common people house as a kind of commodity.Automobile brings convenience with simultaneously efficiently in the trip of giving us, and the antitheft problem of its parts and spare part also is placed in front of us.Through investigating, because stepney and storage battery are installed and the dismounting simple and convenient, spare tyre generally all is placed on behind the car or under the car in addition, and the driver is not easy to observe and notice that this just steals spare tyre with opportunity to the burglar; After operator's compartment is left in driver's parking, storage battery has also become one of main objective of burglar's theft, therefore, show outstanding stolen phenomenon day of stepney and storage battery, and also do not have in the market a kind of can the effective device that plays the anti-theft alarm effect when stepney and storage battery are stolen.Spare tyre and storage battery are stolen, and this not only brings economically loss to the car owner, and bring beyond thought difficulty and trouble can for car owner's trip way especially far away travelling.Chinese patent (patent No. ZL022325255) has been announced a kind of " automobile spare tire burglar alarm ", and it is to use two return micro-switchs and relay as triggering part, makes power supply with storage battery, sends alerting signal with loudspeaker and light-emitting diode.Though it have be quick on the draw, simple in structure, practical characteristics, also exist volume big, inconvenience, damageable shortcoming be installed.

Three. summary of the invention:

Stolen in order effectively to prevent stepney and storage battery, the utility model provides a kind of electronic type automobile spare tire and storage battery burglar alarm.This electronic anti-theft alarm is can be at automobile spare tire and storage battery stolen or in time send the sound and light alarm signal when losing, even also can in time send the sound and light alarm signal when this electronic alarm is destroyed.

This utility model is achieved in that it is made up of main frame, power-supply system, on-off system, warning and lead etc.

Main frame by the body box, with circuit card weldering be that the transistor and the resistance of one constitutes.The body box is made by metal or plastics, the promptly interior power supply of built-in circuit plate and rechargeable battery.Transistor and resistance are one by circuit that designs and circuit card weldering, form a checking system and a power amplification system, and in order to reduce volume, a power supply voltage stabilizing charge system is also welded in convenient installation on the circuit card.Whether the effect of checking system is to detect outer lead to disconnect, and reports to the police as disconnecting then producing, and the effect of power amplification system is that the enough power of output sends alerting signal to promote acousto-optical device, and power supply voltage stabilizing charge system is in order to guarantee safe power supply.Main frame has four external wires, and lead and storage battery are that the positive pole of external power links, and a contact of lead and micro-switch links, another root is an output lead, link to each other with a joint of master cock, also have one to be zero line altogether, with storage battery be that the negative pole of external power links.

Power-supply system is that storage battery, interior power supply are that rechargeable battery, voltage-stable transistor, charging transistor, resistance etc. are formed by external power, they form a voltage stabilizing charging closed loop circuit, thereby external power makes electronic alarm that the dual power supply power supply be arranged just constantly for interior power source charges like this, has autonomous system of one's own and is not subjected to external action with the power supply that guarantees warning device.

On-off system comprises master cock and micro-switch; Master cock generally is installed on the bridge instrumentation dish or operation place smoothly, when stopping or driver when leaving automobile, in case of necessity also can be in driving way, the connection of all master cock can being closed, two contacts of master cock respectively with main frame and warning UNICOM; Micro-switch can be installed on the shelf of placing spare tyre and the contacted position of spare tyre, and one contact zero line together joins, and another contact connects with checking system; Under the normal circumstances, under the pressure of spare tyre, micro-switch is connected, and stolen or when losing, to the pressure releasing of micro-switch when spare tyre, micro-switch just disconnects, the detected system of the voltage signal of this variation detects, and input work place system after amplifying is under the impetus of power amplification system, warning just can be sent the sound and light alarm signal, and prompting driver or other staff in time find and prevent that spare tyre is stolen or lose the phenomenon generation.When storage battery is stolen, its anodal wiring just can disconnect, cause change of voltage, the detected system of this change of voltage detects, input work place system after amplifying, under the impetus of power amplification system, warning also can be sent the sound and light alarm signal, and prompting driver or other staff in time find and prevent that storage battery is stolen or lose the phenomenon generation.

Warning is made of loudspeaker and lighting transistor, and their parallel connections should be installed in the driver and be easy to observe the place of listening to or can bring into play its acousto-optic usefulness.

The utlity model has be quick on the draw, simple in structure, characteristics that volume is little, in light weight, durable in use, easy for installation, under vehicle ', stop situation, all can find effectively and prevent that the spare tyre of automobile and storage battery are stolen or lose, the utility model still can be brought into play its warning function when externally circuit is destroyed, can be applied to the various vehicles that carry spare tyre and storage battery.
