Double-security anti-theft emergency device for batteryless motor vehicles
A double-security anti-theft emergency switch, specially suitable for batteryless race motor vehicles comprising a fixed assembly integral with the vehicle and cooperating with a movable key which is tied up to the driver by means of an even partially elastic lace, is disclosed. The double security is bound to the presence of a first normally closed switch whose opening, via the movable key, is necessary to disconnect the ignition circuit of the motorcycle from ground and to allow the engine to start-up, so as to produce the electrical power necessary for an RFID system to monitor a transponder comprised in the movable key. Should the outcome of this transponder test be unsuccessful, a second normally open switch would be closed and would ground the ignition circuit of the engine and lock the motorcycle.
1. An anti-theft emergency device for vehicles with non-motorized start-up and without electrical battery, comprising: a fixed assembly, integral with the vehicle and functionally cooperating with a movable key connectable to the driver's body, said fixed assembly and said movable key including reciprocal engagement means; said fixed assembly comprises an RFID system, receiving electrical power from the operation of the engine, and comprising at least one identification module which, via at least one antenna, exchanges electromagnetic waves with a transponder associated with said movable key, said identification module also monitors the waves radiated back by said transponder as a response, and grounds the ignition circuit of the engine whenever said transponder is not identified, characterized in that said fixed assembly comprises a normally closed REED switch, whose closing grounds the ignition circuit of the engine, and in that said movable key comprises at least one magnet to open said switch and this way to allow the operation of the engine which generates the electrical power necessary for the operation of said RFID system and to monitor said transponder.
2. An anti-theft emergency device according to claim 1 , characterized in that said identification module receives power from a voltage regulator, which in turn supplies power to a microcontroller, the latter interfaces at least to said identification module and to a relay which is capable of grounding the ignition of the engine whenever said transponder is not identified.
3. An anti-theft emergency device according to claim 2 , characterized in that said RFID system receives power from a voltage regulator which outputs the correct power values after a short period of time and consequently said monitoring takes place after a short period of time.
4. An anti-theft emergency device according to claim 1 , characterized in that said transponder is of a passive type and said movable key does not receive electrical power.
5. An anti-theft emergency device according to claim 4 , characterized in that said identification module receives power from a voltage regulator, which in turn supplies power to a microcontroller, the latter interfaces at least to said identification module and to a relay which is capable of grounding the ignition of the engine whenever said transponder is not identified.
6. An anti-theft emergency device according to claim 5 , characterized in that said RFID system receives power from a voltage regulator which outputs the correct power values after a short period of time and consequently said monitoring takes place after a short period of time.
7. An anti-theft emergency device according to claim 1 , characterized in that the reciprocal engagement means between said movable key and said fixed assembly are of a mechanical and/or magnetic type.
8. An anti-theft emergency device according to claim 1 , characterized in that said movable key is connected to the driver via an at least partially elastic thread-like element.
9. An anti-theft emergency device according to claim 1 , characterized in that said fixed assembly comprises a LED indicator device.
