Abstract
The utility model discloses an anti-theft device, concretely an intelligent anti-theft annunciator of a battery jar of an electric vehicle, which is applied to electric vehicles. An integrated circuit board of the anti-theft annunciator is connected with a sounder D through a power source with the voltage of positive nine volts, connected with a high-level circuit and a lower-level circuit through two composite triodes 2N3904 and connected with a control switch TP1. As the anti-theft annunciator is arranged at a gap position in the bottom of a battery jar box, the vehicle-mounted battery jar is uneasy to be found and removed when being adopted as the power source, and the anti-theft annunciator can emit the alarming sound accurately when the battery jar is stolen. If the thief does not put down the battery jar, the alarming sound continues, thus providing tracked alarming along with the movement and achieving the goal of frightening the thief and alerting people. The intelligent anti-theft annunciator of the battery jar of the electric vehicle has small volume, light weight, convenient installation, good stability and high reliability.
Description
Technical field:
The utility model relates to a kind of antitheft apparatus, specifically is the intelligent electric motor car battery anti-theft alarm that is applied to battery-driven car.
Background technology:
Along with fast development of society, the raising of people's living standard, battery-driven car is very popular with advantages such as its energy-saving and environmental protection, convenience.What but people were the most worried is that storage battery is usually stolen, has caused loss of user's certain economic and inconvenience.
The utility model content:
It is a kind of removable and follow the tracks of to report to the police the intelligent electric motor car battery anti-theft alarm of fright thief's battery-driven car that the utility model provides.Its surface-mounted integrated circuit connects sounder D by power supply+9V, is connected with the high-low level circuit by two compound transistor 2N3904, and is connected with master cock TP1.Because the utility model is installed in gap, storage battery box bottom to annunciator, adopts this car level as power supply, be difficult for being realized and removing, when storage battery is stolen, can accurately send chimes of doom.If the thief does not put down storage battery, chimes of doom can not stop always, follows the tracks of warning with moving, and reaches the fright thief, the purpose of reminds people vigilance.And volume is little, and is in light weight, easy for installation, good stability, reliability height.
Description of drawings:
Fig. 1 is a circuit diagram of the present utility model.
The specific embodiment;
As shown in Figure 1, power access end+9V is connected with the battery-driven car storage battery, and surface-mounted integrated circuit is fixedly installed on battery-driven car storage battery box bottom.Surface-mounted integrated circuit connects sounder D by power supply+9V, is connected with the high-low level circuit by two compound transistor 2N3904, and is connected with master cock TP1.
As shown in Figure 1, the high-low level circuit is by master cock TP1 and integrated package 4011a parallel connection, and master cock TP1 is normally closed at ordinary times, and its integrated package 4011a input end is a high level, and mouth is a low level; By diode and integrated package 4011b parallel connection, integrated package 4011b input end is a low level, and mouth is a high level; And with integrated package 4011c parallel connection, integrated package 4011c input end is a high level, and mouth is a low level.So two compound transistor 2N3904 end, sounder D does not ring.Disconnect master cock TP1, making integrated package 4011b input end is high level, and mouth is a low level, and making integrated package 4011c input end is low level, and mouth is a high level, and compound transistor 2N3904 conducting makes sounder D work and sounds the alarm.In case after triggering, closed master cock TP1, chimes of doom can not stop yet.Though because integrated package 4011a input end becomes high level again after the master cock TP1 conducting, alarm does not stop.
As shown in Figure 1, a hidden switch TP2 and integrated package 4011b parallel connection are set also in integrated circuit, are used for control level annunciator when charging and do not report to the police.Often open at ordinary times, when the robber escapes back or own charging, be used for a disagreeable chimes of doom is cut off, its integrated package 4011c input end is a high level, and mouth is a low level, just can make compound transistor 2N3904 base stage become low level and ends the chimes of doom termination.
Claims (4)
