Description

one

A device for controlling a toy car is known, comprising a control panel, a playing field, a control light source and a photocell associated with a reversing motor for turning the steering wheels of the car 1.

Its disadvantage is a small gaming effect and the inability to synchronize the movement of the beam and the car to illuminate one of the receivers at high speeds of the car.

The purpose of the invention is to enhance the gaming effect.

This is achieved in that the device has additional light sources. Curved stripes of reflective material are applied to the field and windows are made under which additional light sources are installed, and the light source and photocell are located on the bottom of the car.

FIG. 1 shows the described device, a general view; in fig. 2 - the playing field, top view; in fig. 3 is the same, view A in FIG. 2; in fig. 4 - basic electrical control circuit; in fig. 5 is a general view of the device, the second embodiment.

The device comprises a platform 1 of a toy car, on which a control motor 2 is mounted. A gear 3 is mounted on the shaft of the latter, located

in engagement with gear 4, located on shaft 5, designed to convert the rotation of the engine into an angular movement of the lever 6 connected to the rod 7, the ends of which are connected to the two shoulders rocking chair 8. On the axis 9 of the rocking chair wear the steering wheels 10. With the rod 7, a lever 11 is connected to close the contacts 12 and 13 to turn off the steering wheel centering mechanism. Adjacent to the control motor, limit switches 14 and 15 are installed on the platform, made in the form of plate-type relays 16 and 17 for powering the control motor,

receivers 18 and 19, made in the form of photoresistances, polarized relay 20 and drives. The latter consists of an engine 21, the gear shaft of which is meshed with gear 22, mounted on the shaft 23 of the drive wheels 24. Batteries 25 are installed to power the control engine, and brushes 26 mounted on the platform for contacting the tires 27 featured on the game

field on the road following the car. The path of the vehicle following is on a transparent bearing surface 28 made of a transparent material, such as Plexiglas, on one side of which is pasted.

tires, and on the other, “paper 29 f

cutouts 30 in the form of emitters are strips located on the following path, adjacent to light-insulating glasses 31 with light bulbs 32. From the bottom, glasses 31 are covered with a common casing 33. Consoles 34 and 35 adjacent to the bearing surface 28 are mounted to power the light bulbs 32 and tires 27.

On a circuit diagram, contacts 36 and 37 of relay 16 and 17 are closed with a wide 38 battery supply 25, and contacts 39-42 of relay 16 and 17, contacts of limit switches 14 and 15 of engine 2, contacts 12 and 13 of centering switches, contacts 43 and 44 relays 20 are open. This position of the contacts corresponds to the neutral position of the control wheels and the symmetrical arrangement of the photoresistances 18 and 19 relative to the radiator 45.

The device works as follows.

When the tires 27 and the light bulb -32 are turned on, the traction motor 21 is turned on and the car travels along a straight line for a certain length of time. Since the cutout outline - strip 30 is curvilinear, the photoresistance 19, located on the left side, is illuminated, its resistance decreases and the current from the battery 25 passes through it, which enters the winding of the polarized relay 20. The contacts 14 of the latter close and turn on neni) power relays 16. Contacts 39, 41 relays 16 close the motor power supply circuit. The engine, through gears 3 and 4, transmits rotation to the shaft 5. The shaft moves the lever 6, and with it and 7, which in turn moves the two arms of the rocker 8 and the control wheels 10 to the left. Turning the car to the left continues until the photoresistance

19, a signal from a light emitting band is received. When the signal to the photoresistance 19 is stopped, its resistance will increase, and the current passing through it will not be sufficient to hold the contacts 43 of the polarized relay

20 in the closed position. When the contacts 43 open, the power supply of the relay coil 16 stops and its contacts 36, 41 return to their normal initial position.

Simultaneously, when turning the shaft of the control motor, contacts 12 and 13 of the centering mechanism switch close, and the current from the common bus is through normally closed contacts 36 of relay 16 and, closed contacts 13 of the centering mechanism switch enters the winding of relay 17. Contacts 40 and 42 of relay 17 close and turns on the power supply circuit of the engine 2, driving it into rotation, opposite to the original one. The rotation of the engine continues until contacts 13

relay 17 and its contacts 40 and 42 return

in the open position. At the same time, the control wheels 10 are moved to the neutral position, ensuring a straight movement of the vehicle. If the photoresistance is 19, located on the left side,

after some movement of the car along the direct path will again be illuminated, then all the details described in it will work in the same sequence. If the photoresistance 18 located on the right side of the car turns out to be lit, then the work of the parts 44 is performed sequentially; 17; 42; 3, 4, 5, 6, 7, 8, 10, 19, 37, 40, 43, 14, 12, 16, 42, 39, 2, 12, 10 respectively, and the car turns

to the right.

This movement of the car continues until all the lights 32 are on.

When the light bulb of the light-emitting strip that is in front of the vehicle is turned off, the latter continues its movement along the straight line. Since everything is shorter than the curve of its envelope, instead of getting from the contact strip 44 to the contact strip 46 through the contact strip

47, it falls onto the contact strip 46, near the contact strip 47, thereby saving a path and, consequently, saving time. Therefore, the engine 48 drives the car 49, moving strictly along the path.

However, successful overtaking is possible only if the light-emitting strips are skillfully turned on, which is achieved by training, developing in the process of competition between two or more motorists who control their cars by means of the console 34 and 35.
