Abstract
The utility model relates to an anti-theft license plate, which belongs to the technical field of automobile part manufacturing. The anti-theft license plate comprises a license plate and a control circuit connected with the license plate, wherein bolts for fixing the license plate and the license plate constitute switches of the control circuit, the control circuit consists of a power supply, resistors, a transistor, a buzzer, a light-emitting diode and four switches, the resistors are connected with the anode and the cathode of the power supply after being connected with the four switches in series, the base electrode of the transistor is connected with the resistor between the resistor and the switch, one of another two electrodes of the transistor is connected with the anode of the power supply, the other electrode of the transistor is connected with the buzzer, and the input end of the buzzer is connected with the cathode of the power supply via the light-emitting diode. The anti-theft license plate controls the on and off of the power supply by the contact situation of the bolts and the license plate, and has the advantages of anti-theft performance, convenient use, strong practicability and the like.
Description
Technical field
The utility model relates to a kind of antitheft car plate, belongs to vehicular spare parts manufacturing technology field.
Background technology
Though now most of luxury cars all have anti-theft system, major part does not possess the license-plate anti-theft system, and particularly in recent years along with the popularizing of automobile, the case stolen about car plate constantly rising.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, easy to use, practical antitheft car plate.
The utility model is achieved through the following technical solutions:
The utility model comprises car plate and car plate bonded assembly control circuit, wherein, fixedly the bolt of car plate and car plate are formed the switch of control circuit, described control circuit is made up of power supply, resistance, aerotron, buzzer phone, light-emitting diode, four switches, after connecting, resistance and four switches are connected on the both positive and negative polarity of power supply, the base stage of aerotron is connected on the circuit between resistance and the switch, the positive pole that is connected power supply in other the two poles of the earth of aerotron, another is connected on the buzzer phone, and the input end of buzzer phone is pulled in the negative pole of power supply by light emitting diode string.
Described car plate and bolt are made up of conductive iron or metallic material.
The utility model has advantages such as theftproof performance is strong, easy to use, practical by the break-make that whether contacts control circuit of bolt with car plate.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model;
Fig. 2 is the utility model control circuit figure.
Wherein, 1-controller; The 2-car plate; The 3-bolt
The specific embodiment
Embodiment: structure as depicted in figs. 1 and 2, comprise car plate 2 and with car plate bonded assembly control circuit 1, wherein, fixedly the bolt 3 of car plate and car plate 2 are formed the switch of control circuits, described control circuit 1 is by power supply, resistance, aerotron, buzzer phone, light-emitting diode, four switches are formed, resistance and the both positive and negative polarity that is connected on power supply after four switches are connected, the base stage of aerotron is connected on the circuit between resistance and the switch, other the two poles of the earth of aerotron, a positive pole that is connected power supply, another is connected on the buzzer phone, and the input end of buzzer phone is pulled in the negative pole of power supply by light emitting diode string.Above-mentioned car plate and bolt are made by conductive metallic material.Aerotron is cs9013, and resistance is 0.2 kiloohm.
Circuit working of the present utility model is under the voltage control of 5v, and under normal circumstances, bolt is connected with car plate and is in conducting state, can know the low level of transistor base this moment from circuit diagram, therefore aerotron is in off condition, and buzzer phone can not send chimes of doom, and diode can be not luminous.When occurring in the circuit diagram when car plate that stolen or screw rod is backed out during four some disconnections of button, bolt and car plate are in not contact condition, be equivalent to a certain button disconnection in the circuit, the base stage of aerotron is a high level, at this moment aerotron conducting, through buzzer phone, light-emitting diode, sound and light alarm was reminded the driver after electric current amplified through aerotron.
