That is, when the car key is turned to start, at the same time the ignition switch (7) closes the circuit so that voltage can pass to the ignition signal terminal (IG), thus allowing the radio transmitter (1) to detect the car's starting status when voltage is applied through channel (d). - Channel (e) is connected to ground. - Channel (f) is connected to the (COM) terminal of the microswitch (6), which sends voltage to activate the microswitch (6) to detect the "locked" or "unlocked" state of the car anti-theft device. - Channel (g) is connected to the (NO) terminal of the microswitch (6), which detects the "locked" state of the car anti-theft device. - Channel (h) is connected to the (NC) terminal of the microswitch (6), which detects the "unlocked" state of the car anti-theft device. The second part is the Radio Frequency Receiver circuit, which provides a receiver (3) to take the main role in controlling the engine start protection circuit, while the anti-theft device The car is locked by connecting leg (4a) of relay (4) to signal channel (i) of the radio receiver (3), and leg (4b) of relay (4) to signal channel (j) of the radio receiver (3), the positive signal from the battery is connected directly to signal channel (k) of the radio receiver (3), and the ground is connected to signal channel (I) of the radio receiver (3), respectively. In addition, the relay (4) is connected in series with the car ignition switch (7).

The electrical circuit for indicating the status of the mechanical locking car anti-theft device according to Patent 1, in which the electrical circuit operates as follows: When the car anti-theft device is triggered to lock, a mechanical part of the device activates microswitch (6), causing a voltage signal from channel (f) of the radio transmitter (1) to flow through the (COM) terminal to the (NO) terminal of microswitch (6). The microswitch (6) then sends a “locked” signal to channel (g) of the radio transmitter (1) to acknowledge the “locked” state. Once the radio transmitter (1) processes and confirms that the car anti-theft device is locked, it supplies a 2.2 volt voltage through channel (a) to the fluorescent lamp (2) via terminal (2a) and then out through terminal (2b) to return to The radio transmitter (1) through channel (b) causes the light-emitting lamp (2) to light up. Whenever the ignition switch (7) is turned to the ignition signal terminal (IG) position of the vehicle, voltage flows from the said ignition signal terminal (IG) to channel (d) of the radio transmitter (1), causing the said radio transmitter (1) to transmit a radio signal to The radio transceiver (3) controls the operation of relay (4) by sending a voltage from channel (i) to relay (4) via terminal (4a), then through the magnetic field coil to terminal (4b) to send a signal back to channel (j) of the radio receiver (3), resulting in relay (4) opening the circuit. Thus, even if the ignition switch (7) is turned to the start signal terminal (ST) to start the engine, the voltage that flows from the start signal terminal (ST) to terminal (4c) of relay (4) will not be able to flow to terminal (4d) of relay (4) to activate the car start relay (5). 3.

The microswitch (6) then sends a “locked” signal to channel (h) of the radio transmitter (1) to acknowledge the “locked” state. When the radio transmitter (1) processes and confirms the car anti-theft device is locked, it stops supplying 2.2 volts of voltage through channel (a), causing the fluorescent lamp (2) to turn off. At the same time, the radio transmitter (1) sends the unlock signal to the radio receiver (3) to stop supplying voltage through channel (i) to terminal (4a) of relay (4). When the ignition switch (7) is turned to the start signal terminal (ST) to start the car, the relay is activated.

Electrical circuit for displaying the status of a mechanically locked car anti-theft device, in which the electrical circuit has the following characteristics: Part one, Radio Frequency Transmitter circuit, in which a radio transmitter (1) is provided, which performs the main function of alerting and preventing the engine from starting while the car anti-theft device is locked. In which the radio transmitter (1) is connected to the relevant components as follows: - Channel (a) is connected to terminal (2a) of the fluorescent lamp (2) to receive a positive voltage of 2.2 volts to power the fluorescent lamp (2). - Channel (b) is connected to terminal (2b) of the fluorescent lamp (2) to provide a negative voltage of 2.2 volts back to the transmitter (1). - Channel (c) is connected to the positive signal from the battery to receive the voltage used to power the radio transmitter (1). - Channel (d) is connected to the ignition signal terminal (IG) of the car ignition switch (7), which serves to detect the car's starting status, i.e., when the ignition key is turned to start the car.

The electrical circuit for indicating the status of a mechanically locked car anti-theft device according to Patent 1, in which the operation is such that when the car anti-theft device is activated to lock, the mechanical parts of the car anti-theft device activate the microswitch (6), resulting in the voltage signal from channel (f) of the radio transmitter (1) being able to flow through the (COM) terminal to the (NO) terminal of the microswitch (6). The microswitch (6) then sends a "locked state" sensing signal to channel (g) of the radio transmitter (1) to acknowledge the "locked state". When the radio transmitter (1) processes and confirms that the car anti-theft device is locked, it supplies a voltage of 2.2 volts through channel (a) to a fluorescent lamp (2) through terminal (2a) and then out through terminal (2b) to return to The radio transmitter (1) via channel (b) causes the fluorescent lamp (2) to light up. Whenever the ignition switch (7) is turned to the ignition signal position (IG) of the vehicle, voltage flows from the ignition signal position (IG) to channel (d) of the radio transmitter (1), causing the radio transmitter (1) to send a radio signal to the radio transceiver (3) to activate relay (4). By sending voltage from channel (i) to relay (4) via terminal (4a), and through the magnetic field coil to terminal (4b), it sends a signal back to channel (j) of the radio receiver (3), causing relay (4) to open.
