The disclosure and prior art relates to anti-theft devices and more particularly pertains to a new anti-theft device for disabling a stolen vehicle.
An embodiment of the disclosure meets the needs presented above by generally comprising a transmitter and a receiver. The transmitter comprises a transmitter housing having a front face separated from a rear face, a top face separated from a bottom face, and a left face separated from a right face. The front face, the rear face, the top face, the bottom face, the left face, and the right face form a transmitter cavity therebetween. A transmitter circuit system is coupled to the transmitter housing within the transmitter cavity. The transmitter circuit system has a communication transmitter means. A power supply is coupled to the transmitter housing within the transmitter cavity and has a charging port extending through the right face. The power supply is in operational communication with the transmitter circuit system. A power switch is coupled to the front face of the transmitter housing and is in operational communication with the power supply. The receiver comprises a receiver housing having a front panel separated from a rear panel, a top side separated from a bottom side, and a left side separated from a right side. The front panel, the rear panel, the top side, the bottom side, the left side, and the right side forming a receiver cavity therebetween. A vehicle connect cable is coupled to the receiver housing, extends through the rear panel, and is configured to connect to an electronic system of a vehicle. A receiver circuit system is coupled to the receiver housing within the receiver cavity and is in operational communication with the vehicle connect cable. The receiver circuit system has a communication receiver means and a vehicle electronics integration means. The communication receiver means receives a signal from the communication transmitter means to detect the proximity of the transmitter. The vehicle electronics integration means is configured to disable the electronic system of the vehicle to prevent it from driving when the receiver is at least a predetermined distance from the transmitter.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The receiver 14 comprises a receiver housing 54 having a front panel 56 separated from a rear panel 58, a top side 60 separated from a bottom side 62, and a left side 64 separated from a right side 66. The front panel 56, the rear panel 58, the top side 60, the bottom side 62, the left side 64, and the right side 66 form a receiver cavity 68 therebetween. A vehicle connect cable 69 extends through the rear panel 58 of the receiver housing and is configured to connect to an electronic system of a vehicle, including the ignition switch, fuel pump, spark plugs, and fuel injectors. A receiver circuit system 70 is coupled within the receiver cavity 68 and is in operational communication with the vehicle connect cable 69. The receiver circuit system 70 has a communication receiver means 72 that may comprise a 418 Mhz encoder 74. The receiver circuit system 70 also has a vehicle electronics integration means 76 and may have a brake detection means 78, a bypass means 80, and a reset means. The communication receiver means 72 receives a signal from the communication transmitter means 40 to detect the proximity of the transmitter 12. The vehicle electronics integration means 76 is configured to disable the electronic system of the vehicle to prevent it from driving when the receiver 14 is at least a predetermined distance from the transmitter 12. The predetermined distance may be between 15-30 meters. The brake detection means 78 is in operational communication with the vehicle electronics integration means 76 and is configured to detect when a brake of the vehicle is depressed and cause the vehicle electronics integration means 76 to only disable the electronics system of the vehicle when the brake is depressed. As such the user may leave the vehicle running when she exits with the transmitter 12, but if someone enters the vehicle and depresses the brake to try to put the vehicle in gear the vehicle will be disabled. The reset means is in operational communication with the vehicle electronics integration means 76. The reset button 44 activates the reset means of the receiver circuit system to reenable the electronics system of the vehicle after it has been disabled by the vehicle electronics integration means 76. The bypass means 80 disables the vehicle electronics integration means 76 when activated. The receiver circuit system 70 may have a plurality of 12V relays 82, a 12V-3.5V step-down power supply 84, a 3.5V relay 86, a pair of NPN transistors 88, and a PNP transistor 90. A bypass switch 92 may be coupled to the receiver housing 54 and extends through the front panel 56 and is in operational communication with the receiver circuit system 70. The bypass switch 92 activates and alternatively deactivates the bypass means 80. There may be a bypass indicator light 94 coupled to the receiver housing 54 and extending through the front panel 56. The bypass indicator light 94 is in operational communication with the bypass switch 92 and illuminates when the bypass means 80 is activated. A car power indicator light 96 may be coupled to the receiver housing 54 and extends through the front panel 56. The car power indicator light 96 is in operational communication with the vehicle electronics integration means 76 and illuminates green when the electronics system of the vehicle is active and red when the electronics system of the vehicle is inactive. A communication indicator light 98 may be coupled to the receiver housing 54 and extends through the front panel 56. The communication indicator light 98 is in operational communication with the communication receiver means 72 and illuminates green when the transmitter 12 is within the predetermined distance of the receiver 14 and illuminates red when the transmitter 12 is beyond the predetermined distance or is powered off.
In use, the receiver 14 is linked to the vehicle with the vehicle connect cable 70. The user keeps the transmitter 12 on her person and activates it using the power switch 50. If the user then leaves the vehicle or it is stolen from her, the vehicle electronics integration means 76 will disable the electronics system of the vehicle to prevent it from driving once the receiver 14 moves beyond the predetermined distance. In order for the vehicle to be operable again, the user presses the reset button 44 on the transmitter to activate the reset means of the receiver.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
