This invention relates to devices for providing remote control of toys.

The aim of the invention is to increase the noise immunity.

The drawing shows the block diagram of the device.

The device for controlling a self-propelled toy consists of a source of 1 audio signals, a receiver of 2 audio signals, and an electronic time relay 3. 4 strokes, schemes 5 prohibiting forward travel for reversing time, and electric drive control schemes 6, as well as electric drive 7 and inertial switch 8 of forward travel. In the initial state, in the absence of a sound signal, the time relay outputs 3.4 are de-energized, the power supply voltage is not applied to the electric drive 7 — the toy is stationary.

The device works as follows.

When sound signals are received from sound source 1, a voltage sufficient to start time relay 3 appears at the output of receiver 2, the voltage from its output through the inhibitor circuit 5 goes to the drive control circuit of the electric drive 6, which supplies the power supply voltage to the electric drive 7 - forward movement. Time relay 3 is insensitive to restarting during the formation of a time interval, which prevents malfunction of the control device from acoustic ujyMOBs and electrical noise generated by the electric drive 7. After the time relay 3 finishes, the electric drive is de-energized, the device returns to its initial stop state. If the toy runs into an obstacle while moving forward, the inertial switch 8 of the forward stroke closes briefly, turning on the time relay 4. The voltage from the reverse time relay 4 output goes to the inhibitor circuit 5, which disconnects the relay 3 output from the electric drive control circuit 6 drive 7 is de-energized. At the same time, the voltage from the output of the time relay 4 is fed to the control circuit of the electric actuator 6, which supplies the electric actuator 7 with the supply voltage

reverse sexuality - the toy moves backward with a turn. The operating time of the reverse time switch 4 is sufficient to turn the toy at an angle of 90 °, which at a speed of 0.5 m / s is 2 seconds. After the end of operation of the time relay 4, the voltage is removed from the prohibition circuits 5 and the 6 drive controls. The voltage from the output of the time relay 3 is supplied to the electric drive control circuit 6 - the toy moves forward until the end of the work

Time relay 3. Time of operation of time relay 3 is selected several times longer than the time of operation of relay 4 to ensure a sufficiently long forward movement. An advantage of the invention is higher sensitivity and noise immunity. High noise immunity of the device is ensured by the absence of the need for sound control during movement.
