Abstract
The utility model discloses a charging anti-theft alarm for an electric vehicle. The charging anti-theft alarm is provided with a box body, wherein an input socket and an output socket are arranged at two ends of the box body respectively; and the negative ends of the input socket and the output socket are connected with each other through a lead wire. The charging anti-theft alarm is characterized in that bidirectional controllable silicon is connected between the positive ends of the input socket and the output socket through a second lead wire; the control pole of the bidirectional controllable silicon is connected with the positive end of the output socket through a button switch to form a trigger loop; a relay is connected between the positive end and the negative end of the output socket; and an alarm circuit controlled by a normally closed contact of the relay is arranged in the box body. The charging anti-theft alarm has the advantages of high anti-interference performance, high anti-theft property, simple structure and low manufacturing cost, can alarm timely and accurately and is convenient to use and suitable for outdoor charging of electric vehicles.
Description
Technical field
The utility model relates to a kind of burglar alarm, particularly a kind of battery-driven car charging burglar alarm.
Background technology
Along with popularizing of battery-driven car, the battery-driven car difficult problem of charging highlights day by day, and for the ease of charging and laborsaving, much human is locked in oneself with battery-driven car and power supply is guided to downstairs downstairs and through insert row and charged, and easy like this battery-driven car or the battery of causing is stolen.And the burglar alarm on the prior electric car is mainly controlled through acoustic control or induction, and this burglar alarm receives ectocine bigger, in case receive various interference flase alarm takes place easily, and it is difficult to distinguish the true from the false to make the car owner.
Summary of the invention
The utility model technical matters to be solved is that a kind of strong interference immunity will be provided, and it is timely, accurate to report to the police, the battery-driven car charging burglar alarm that theftproof performance is good.
The utility model is achieved in that it has a box body; Be respectively equipped with input socket and accessory power outlet at the box body two ends; The negative terminal of input socket and accessory power outlet links to each other through lead; Its special character is: between the anode of input socket and accessory power outlet, be connected to triac through lead; The control utmost point of triac links to each other with the accessory power outlet anode to form through button switch and triggers the loop, between the positive and negative end of accessory power outlet, is connected to relay, in box body, also is provided with the warning circuit by the control of relay normally closed contact.
Above-mentioned battery-driven car charging burglar alarm, described warning circuit is to be in series by battery pack, alarm switch, described relay normally closed contact and siren horn.
Above-mentioned battery-driven car charging burglar alarm is plugged with the charge power supply line on accessory power outlet.
The utility model has the advantages that: strong interference immunity, it is timely, accurate to report to the police, and theftproof performance is good, and simple in structure, easy to use, and low cost of manufacture is applicable to the outdoor charging of battery-driven car.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the schematic circuit diagram of the utility model.
Among the figure: box body 1, button switch 2, input socket 3, alarm switch 4, accessory power outlet 5, charge power supply line 6, relay 7, normally closed contact 701, siren horn 8, battery pack 9, triac 10.
The specific embodiment
As shown in the figure; The utility model has a box body 1; Be respectively equipped with input socket 3 and accessory power outlet 5 at box body 1 two ends; Input socket 3 links to each other through lead with the negative terminal of accessory power outlet 5, between the anode of input socket 3 and accessory power outlet 5, is connected to triac 10 through lead, and the control utmost point of triac 10 links to each other with accessory power outlet 5 anodes to form through button switch 2 and triggers the loop.Between the positive and negative end of accessory power outlet 5, be connected to relay 7, the coil two ends of relay 7 are connected on respectively on two leads that connect accessory power outlet 5 positive and negative ends.In box body 1, also be provided with the warning circuit by normally closed contact 701 controls of relay 7, described warning circuit is to be in series by battery pack 9, alarm switch 4, described relay normally closed contact 701 and siren horn 8.On accessory power outlet 5, be plugged with the charge power supply line 6 that is used to connect battery of electric vehicle.
During use, charging battery of electric vehicle device output plug is inserted input socket 3, accessory power outlet 5 is guided to outdoor charging jack with battery of electric vehicle through charge power supply line 6 peg graft, again the battery charger attaching plug is inserted in the indoor 220V supply hub.Press the button switch 2 then, triac 10 is opened in triggering loop conducting, the charge circuit conducting, relay 7 gets electric adhesive, begins battery of electric vehicle is charged; Simultaneously alarm switch 4 is closed, this moment, the relay normally closed contact broke off, and siren horn 8 can not reported to the police.When the people pulled out or cut off charge power supply line 6, triac 10 automatically shut down, the coil blackout of relay 7, and its normally closed contact is connected, and makes the warning circuit conducting, and siren horn 8 is reported to the police immediately, and the car owner can in time be reacted.
