Abstract
The utility model discloses an automobile electric theft-proof alarm device with high reliability, low cost, and strong practicality. The host machine of an alarm is locked in a firm metal cabinet, and the door of the cabinet is provided with the mechanical secret code and a control lock. The driver can use the mechanical secret code and the control lock to control the working condition of the alarm device. The external connection lead wires of the point of the igniting coil of the automobile, a plurality of signal transmission wires, and a plurality of foggy wires are sealed together to difficult to identify. Besides, the utility model is provided with an emergency calling button and a delayed alarm switch. The inner part of the cabinet and the inner wall of the front cover of the automobile head are respectively provided with an oblique vibration sensor. Under the conditions of having no the key of the control lock and knowing the number of the secret code, the automobile can not be started. If the thief passes around the igniting coil, the control device of a low pressure side circuit is shorted directly, and the alarm is easy to touch to ring. The driver presses the emergency calling button or the delayed alarm switch, and the alarm can be send out and the fire can be went out immediately or subsequently. When the thief smuggles the automobile or opens the front cover of the automobile to steal the valued parts, the oblique vibration sensor are switched on, and strong alarm can be send out by an alarm circuit.
Description
The utility model relates to a kind of automobile electronic anti-theft alarm.
Existing alarming device for automobile anti-theft, the price comparison costliness that has, the function that has is not too complete, and in recent years, the stolen existing picture of automobile is very serious both at home and abroad, and car theft has become great society public hazards, has caused the very big concern of social each side.
The purpose of this utility model is intended to design a kind of practical, reliable operation, cheap multifunction automobile electronic antitheft alarm system.When the robber steals cars with various illegal means or tears the valuable part on the car steathily open or when plundering onboard; mounted in a vehicle warning device all can send strong alarm accurately; and the power supply of cut-out automobile ignition coil, reach the purpose of protecting automobile and driver safety.
The utility model comprises cabinet, the cabinet door, the door lock of switch cubicle door, the door lock key, locknut, fastening Luo bar Luo cap, mechanical cipher, control lock, the control key, pressing plate, hollow overcoat and annunciator, it is characterized in that: mechanical cipher, control lock, pressing plate, tilt and vibration sensor master cock and ignition coil circuit master cock are installed on the cupboard, pressing plate is fixed on the dead bolt of control lock, it stretches out with dead bolt or when withdrawing, can control being switched on or switched off of above-mentioned switch simultaneously, comprise battery case, the battery case cover plate, battery, the switch circuit that contains alarm relay and delayed alarm relay, contain power tube, the warning circuit of sound sheet and loud speaker, the signal relief switch is locked in the cabinet by door lock at interior annunciator main frame part and tilt and vibration sensor, this tilt and vibration sensor can be a mercury contact switch, one normally closed contact of delayed alarm relay 11 is serially connected with in the break signal transmission line circuit, its open contact and delayed alarm switch in parallel are at power end, one normally closed contact of alarm relay and ignition coil circuit master cock are serially connected in the low tension loop of automobile ignition coil, tilt and vibration sensor and tilt and vibration sensor master cock are serially connected with between short-circuit signal transmission line and the signal transmission concentration line, the short-circuit signal transmission line, the break signal transmission line, signal transmission concentration line, synthetic one big strand of puzzled line of mystery and high-tension coil low pressure side external lead wire, its end can place in the hollow overcoat.Press the delayed alarm switch, can disconnect the delayed alarm relay normally closed contact that is connected in the break signal transmission line loop, cause transistor switching circuit time-delay conducting, make the alarm relay action, its open contact is connected warning circuit, touch acoustic warning, normally closed contact cut-off point fire coil lower-voltage circuit makes automobile flameout.At no control lock key with do not know under the situation of mechanical cipher numbering, because of string in the high-tension coil low tension loop has an ignition coil circuit master cock by mechanical cipher and control lock control, at ordinary times, it is open circuited, therefore, automobile can not be realized igniting and start.When mounted, high-tension coil and the external lead wire of external lead wire on automobile that transmits concentration line, high-tension coil low pressure side because of the puzzled line of mystery, short-circuit signal transmission line, break signal transmission line, signal is encapsulated in the hollow overcoat by the very strong insulating packing of viscosity, it is beyond recognition, as long as above-mentioned signal transmssion line is cut off or short circuit, will touch acoustic warning.Even the robber has connected high-tension coil by chance, started automobile, because the vibration that running car occurs, must cause tilt and vibration sensor to connect short-circuit signal transmission line and signal transmission concentration line, make the transistor switching circuit conducting, the alarm relay action, its contact is connected warning circuit respectively, point of cutoff fire coil low pressure side power supply makes it send strong alarm and forces automobile flameout.
In order in time to send an SOS when being plundered, the utility model is provided with the distress call button, and this button is attempted by between short-circuit signal transmission line and the signal transmission concentration line.
For strengthening the warning effect, can outside railway carriage, set up loud speaker, it is contained in the protecgulum of headstock.Be positioned at the situation of headstock at big valuable part of automobile, tear open for preventing that parts valuable on the car are stolen, on headstock protecgulum inwall tilt and vibration sensor has been installed, it is in parallel with the tilt and vibration sensor in being contained in cabinet, and it can be a mercury contact switch.
Be fuzzy sight line of robbing the car criminal, can in car, the relevant position be installed by accent light, it with connect the automobile power source two ends after an open contact of alarm relay is connected.
The utility model can be set up automobile ignition coil, uses the gland sealed operation so that save in the erecting stage.
Below in conjunction with accompanying drawing the utility model is described in detail:
