Abstract
The utility model relates to a charging anti-theft alarm of an electromobile, which comprises a relay, an alarm and a power supply connection piece, wherein one end of the power supply connection piece is of a two-plug, and the other end is of a three-plug, wherein a grounding wire and a zero wire of the three-plug are jointly connected to a grounding column of the two-plug, and a relay coil is in series connected to the grounding wire between the two plugs. When in use, the two plugs are switched on with mains power. The three-plug is connected with a charging three-hole socket on an electromobile, and a phase wire column of the three-hole socket on the electromobile is connected with the grounding column. A phase line and a zero line of the socket are connected with a charging unit of the electromobile. A normally-closed contact point of the relay and the alarm are connected in series to form an alarm circuit. The utility model has the advantages of simple structure and low making cost, and a 'safeguard' is added to hosts of electromobiles by the charging anti-theft alarm of an electromobile. The problem that when charged, the electromobile is stolen is solved.
Description
Technical field
The utility model relates to a kind of storage battery car charging burglar alarm.
Background technology
Along with expanding economy, storage battery car obtains the speed development with advantages such as its noiseless, pollution and carrying capacity are strong.As everybody knows, reliable, the actv. work of storage battery car is by the guarantee that is used as power of stable, sufficient voltage.So, charging is the work that all car owners must often will do to storage battery car, because charging generally is after work, study to storage battery car, time is many in darkness later night, unavoidable like this have chance to the busybody, losing not only of storage battery car brings the certain economic loss to the car owner, also brings heavy pressure to social security.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple in structure, storage battery car that cost is low charging burglar alarm for society.
Storage battery car charging burglar alarm adopts following technical scheme to address the above problem: it comprises relay, annunciator, it is characterized in that: comprise that also one one end is two plugs, one end is the mains connection of three plugs, wherein, the grounding jumper of three plugs and zero line are connected on the earthing rod of two plugs altogether, relay coil is connected on the grounding jumper between two plugs, and two plugs connect civil power during use; Three plugs connect the three-phase socket that charges in the storage battery car, and the phase terminal of three sockets of charging links to each other with earthing rod in the storage battery car, and the phase line of socket, zero line connect the storage battery car charhing unit; The normally closed contact of relay is connected with annunciator and is constituted warning circuit.
The utlity model has advantage simple in structure, that cost of manufacture is low, the consumption of current of relay is very low, when charging to storage battery car, can any influence not arranged to household electricity, storage battery car charging burglar alarm has increased a bodyguard for the storage battery car car owner, the easy stolen problem of storage battery car when having solved the storage battery car charging.
Description of drawings
Fig. 1 is the attaching parts scheme drawing of the utility model storage battery car charging burglar alarm.
Fig. 2 is three socket scheme drawings of storage battery car charging of the utility model storage battery car charging burglar alarm.
Fig. 3 is the utility model storage battery car charging burglar alarm alarm loop schematic diagram.
The 1-grounding jumper, 2-zero line, 3-phase line, 4-relay coil, 5-earth point, 6-charhing unit, 7-power supply, 8-annunciator, 9-intermediate relay normally closed contact, 10-button
The specific embodiment
In conjunction with the accompanying drawings further introduction is done in the circuit connection of the utility model storage battery car charging burglar alarm, with wire connecting power two plugs and three plugs, wherein, the grounding jumper 1 of three plugs and zero line 2 are connected on the earthing rod of two plugs altogether, with on the grounding jumper 1 between coil 4 polyphones two plugs of relay, constitute attaching parts of the present utility model again.Phase line 3 with three sockets of charging in the storage battery car is connected with grounding jumper 1 again, and the phase line 3 by three sockets connects storage battery car charhing unit 6 as Fig. 2 with zero line 2 then.Power supply 7, emergency alarm bell 8, intermediate relay normally closed contact 9, button 10 series connection are constituted alarm loop, as Fig. 3.
Principle of work: when charging to storage battery car, phase line 3 with three sockets of charging in the storage battery car is connected with grounding jumper 1 earlier, two plugs with attaching parts join by phase line 3, zero line 2 and commercial power socket again, three sockets of charging in three plugs and the storage battery car join, and the button 10 with alarm loop closes again, at this moment, charge to storage battery car on the one hand, while is electric owing to relay gets, and its contact-carrying is disconnected, and alarm loop is not worked.When the utility model power end plug is pulled out or is cut off by the busybody, intermediate relay will because of dead electricity with its contact 9 closures, thereby make the emergency alarm bell that is in series with it get electric work, emergency alarm bell will sound and can wake up with a start car owner or other pedestrian, reaches antitheft purpose.Even (being the charge switch disconnection in the storage battery car) as long as attaching plug, the storage battery car plug of attaching parts are plugged, also has same warning effect under not electrically-charged situation.
