Abstract
The utility model discloses an auto-brand anti-theft device, which comprises two power supplies, an alarm circuit, and an electromagnetic relay. The electromagnetic relay comprises a coil, an elastic sheet, and a contact sheet. The coil of the electromagnetic relay, two auto-brands and the power supplies are serially connected to constitute a closed loop. The contact sheet of the electromagnetic relay corresponds to two contacts of the alarm circuit in a non-contact manner. The two contacts, a horn and the power supplies are serially connected to constitute an alarm circuit. The utility model has advantages of simple structure and low cost and can effectively prevent auto-brand from theft.
Description
One, technical field
The utility model relates to a kind of anti-joyride device, a kind of anti-joyride device that is used on the automotive license plate of saying so more specifically.
Two, background technology
At present, the license-plate anti-theft device is not installed on the automobile, the screw fixedly method of car plate can't well be accomplished the license-plate anti-theft function, therefore, the stolen problem of car plate often occurs, has not only influenced the life order, has also caused economic loss.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, outstanding effect license-plate anti-theft device.
The purpose of this utility model is to be achieved by following technical proposals.
License-plate anti-theft device of the present utility model, it comprises two power supplys, warning circuit, electromagnetic relay, electromagnetic relay comprises coil, shell fragment and contact, the coil of electromagnetic relay, two car plates and power supply are connected into C/LOOP, the contact of electromagnetic relay is corresponding with two contacts of warning circuit, but do not contact, described two contacts, loudspeaker and power supply series connection constitute warning circuit.
The utility model is simple in structure, is easy to processing and manufacturing, can avoid car plate stolen by actv..
Four, description of drawings
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model;
Five, specific embodiment
In Fig. 1, license-plate anti-theft device of the present utility model, it comprises power supply 3, power supply 4, warning circuit 11, electromagnetic relay 10, electromagnetic relay 10 comprises coil 2, shell fragment 9 and contact 1, the coil 2 of electromagnetic relay 10, preceding car plate 7, back car plate 8 and power supply 4 are connected into C/LOOP, the contact 1 of electromagnetic relay 10 is corresponding with two contacts 5 of warning circuit 11, but does not contact, and described two contacts 5, loudspeaker 6 and power supply 3 series connection constitute warning circuits 11.
When car plate is not having when stolen, electromagnetic relay 10, power supply 4, two car plates constitute C/LOOP, and the shell fragment 9 of electromagnetic relay 10 is attracted by coil 2, thereby two and the contact 5 of warning circuit 11 and contact 1 are separated, and warning circuit is disconnected; After car plate was stolen, circuit was cut off, owing to there is not electric current, shell fragment 9 sets back in the coil 2, and two contacts 5 of warning circuit 11 and contact 1 are contacted, and made the warning circuit closure, and loudspeaker send alarm sound, thereby play the effect of anti-theft alarm.
