Abstract
The utility model relates to an anti-theft alarm for an electric motor car, which consists of an alarming chip, a resistor, a triode, a switch and a buzzer. The input terminal of the alarming chip isrespectively connected with the connecting ports of the electric motor car and a storage battery, and the two connecting ports are connected in series; the output terminal of the alarming chip is connected with a base electrode of the triode through the resistor; the buzzer is connected with a collecting electrode of the triode; and the switch is connected in series in the power circuit of the alarming chip. The anti-theft alarm utilizes the fit connections between the unemployed contact points in the connecting ports of the electric motor car, the storage battery and a charger and an anti-theft alarm circuit to achieve the real-time monitoring of the storage battery, so as not only to prevent the storage battery and the electric motor car from being stolen, but also to provide a fast andconvenient charging model for the storage battery. Therefore, the anti-theft alarm has the advantages of simple integral structure, safety, reliability and low cost.
Description
Technical field
The utility model relates to a kind of burglar alarm, particularly a kind of battery-driven car and battery anti-theft alarm of being used for.
Background technology
Walking-replacing tool is a lot of at present, because battery-driven car is quick, conveniently a lot of convenience are provided for the modern, thereby increasing people bring into use the battery-driven car of environmental protection on the market, along with increasing of battery-driven car quantity, the stolen incident of battery-driven car happens occasionally, thereby the annunciator that various structures are installed on battery-driven car to be used for battery-driven car antitheft, though can effectively prevent the generation of the stolen incident of integral electric car, but its complicated integral structure, cost an arm and a leg, do not possess simultaneously anti-theft alarm function to the battery-driven car storage battery, and storage battery is the propulsion source that drives battery-driven car, and often needing be its charging, thereby user's storage battery in order to prevent to charge is stolen, usually storage battery is moved to and indoor it is charged, because most of storage batterys are lead-acid accumulators, weight is heavier, moves comparatively effort, particularly the woman is more difficult, thereby has brought great inconvenience to the user.
Summary of the invention
The utility model purpose is at above-mentioned deficiency, and a kind of battery-driven car and battery anti-theft alarm are provided.
The utility model purpose is achieved in that this battery-driven car and battery anti-theft alarm be made up of alarm chip, resistance, aerotron and switch and buzzer phone, the input end of described alarm chip links to each other with the communication port of battery-driven car and storage battery respectively, be connected in series between its two communication port, the alarm chip mouth connects the base stage of aerotron through resistance, buzzer phone is connected to the collecting electrode of aerotron, and switch series is connected in the electric power loop of alarm chip.
The technological advance that the utility model is obtained: this burglar alarm utilizes and does not utilize being connected of contact and anti-theft warning circuit in battery-driven car and storage battery and the charger communication port, realized real-time monitoring to storage battery, stolen in the time of not only can effectively preventing the storage battery charging, also effectively prevented the generation of the stolen incident of battery-driven car, and provide convenient charge mode easily for storage battery charges.This burglar alarm integral structure is simple, safe and reliable, with low cost.
Description of drawings
Fig. 1 is the utility model integral structure schematic diagram.
The specific embodiment
Be that embodiment is described further the utility model below with the accompanying drawing, as shown in Figure 1, this battery-driven car and battery anti-theft alarm are by alarm chip U, resistance R, aerotron V and K switch and buzzer phone F form, described alarm chip U present embodiment is selected the universal alarm chip of C2002B for use, the input end of alarm chip U links to each other with two contacts that do not utilize in the communication port a3 of the communication port a2 of battery-driven car and storage battery respectively, be connected in series between its two communication port, the mouth of alarm chip U connects the base stage of aerotron V through resistance R, buzzer phone F is connected to the collecting electrode of aerotron V, in the electric power loop of K switch serial connection and alarm chip U.
During use charger communication port a1 is inserted in the storage battery communication port a3, and close switch K, charger is the storage battery charging on the one hand, start anti-theft warning circuit work simultaneously, alarm chip U output this moment active potential, this active potential makes aerotron V end through the base stage of resistance R access aerotron V, and buzzer phone F does not work.When communication port a2, the a3 of battery-driven car and storage battery room and between connection lead when disconnecting, alarm chip U export high potential, this high potential is through the base stage of resistance R access aerotron V, makes aerotron V saturation conduction, buzzer phone F sends chimes of doom.
