Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a direction changing device for a remotely controlled traveling toy.

A known direction changing device of this type is a radio control device. This known direction changing device employs, for example, a pulse width modulation (PWM) method using a carrier wave, and controls the traveling direction etc. by changing the duty ratio of the pulse width modulation (PWM) method.

However, in such a known remote control direction changing device, 1) the entire device becomes large, 2) it is necessary to separately provide a power source for driving (driving) and a power source for driving control, and the device is relatively expensive. Since a power supply that can supply voltage, for example 9V to 12V, is required, the volume occupied by the power supply becomes large. 3) A large number of primary or secondary batteries are required for these power supplies, which increases costs. 4) Direction changing devices using servo motors require high mechanical precision; 5) In order to improve the receiving sensitivity and nozzle resistance of the receiver, the circuit becomes complicated and expensive, etc. There were various shortcomings.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks, and particularly to propose a direction changing device for a remotely controlled traveling toy that is smaller in size, lower in cost, lower in voltage, lower in power consumption, and has a simpler structure.

The direction change in the remote-controlled running toy of the present invention is achieved by a sensor section that generates a gate signal by receiving a direction change transmission signal such as sound, light, radio waves, etc., and a gate signal from this sensor section. An electronic switch that performs a switching operation, a mechanical switch that is connected in parallel with this electronic switch and performs a switching operation by the rotation of a steering lever that controls the direction of travel, a parallel circuit for these electronic and mechanical switches, and a power supply. a running direction switching means connected in series between the steering lever and rotating the steering lever; the electronic switch and the mechanical switch are switched and actuated to cause the steering lever to be rotated by the running direction switching means; This is characterized in that the rotational movement is performed intermittently.

The present invention will be explained below with reference to the drawings.

FIG. 1 is a perspective view of a miniature car incorporating a direction change device in a remotely controlled traveling toy of the present invention. Reference numeral 10 denotes a body of a miniature car, and this body 10 is detachably mounted on a chassis (not shown) on which a conversion device to be described later and the functional parts of the original automobile are mounted. Roof portion 1 of this vehicle body 10
2, a sound collection unit 14 for receiving sound waves for remote control;
is installed.

FIG. 2 is a plan view of the vehicle body 10 with the bottom portion 20 removed. The front wheels 15 and 16 are supported at the top in the drawing, and the rear wheels 17 and 18 are supported at the bottom.
18 is for driving.

First, to explain the electrical system configuration of the direction changing device of the present invention, 22 is a power supply unit, and in this example, 2 AA size ultra-small dry batteries and 2 other batteries are connected in series to provide a 3V power supply.
I am getting . As will be described later, this power source is commonly used for driving (traveling) the automobile and for the direction changing device. Next, an electronic circuit section 24 other than the sound collection section 14 is installed approximately in the center of the bottom section 20. This electronic circuit section 24 is connected to the above-mentioned power supply 22, and the sound collecting section 14 and solenoid coil 26 are also connected to the electronic circuit section 24, but the connecting cable is not shown for simplicity. Finally, the switch portion 28 is arranged at a position that satisfies a predetermined relationship with respect to the steering lever 30, as will be described later. This switch section 28
is also connected to the electronic circuit section 24, but its connection cable is similarly omitted.

Next, the mechanical configuration of the direction changing device of the present invention will be explained. First, the rear wheel 17,1 which is the drive shaft
8 is mounted on an axle 32. In order to transmit rotational force to this axle 32, it is linked to a motor 34 via a drive side gear group 36. A first gear 38 is disposed on the axle 32 on the side opposite to the drive side gear group 36.
Attach. On the other hand, a through hole is formed near the top of the suction shaft 27 of the solenoid coil 26,
An interlocking rod 40 is communicated within this through hole. At one end of this interlocking rod 40 is the first gear 38 mentioned above.
A second gear 42 (pinni pin) that meshes with the crown gear is attached, and a third gear 44 (worm gear) for operating the steering lever 30 is attached to the other end. This interlocking rod 40
is when the second gear 42 is energized while the solenoid coil 26 is energized.
is arranged so as to be able to mesh with the first gear 38. That is, when the coil 26 is in a non-excited state, the suction shaft 27 is located at the position indicated by the broken line in FIG. is beginning to form.

On the other hand, the third gear 4 at the other end of this interlocking rod 40
4 is always in mesh with a fourth gear 46 (gear with a crank). This fourth gear 46 has a disk shape, and teeth are cut into the peripheral edge thereof. A pin 48 is implanted on one plane of the fourth gear 46, and this pin 48 is loosely fitted into the guide groove 50 of the steering lever 30. Further, this steering lever 30 has a cutout groove 52 formed at its tip (upper part of the figure), and is engaged with a pin 56 of a connecting bar 54 for the front wheels 15 and 16 in the cutout groove 52. Further, a fulcrum 5 is provided between this notch groove 52 and the guide groove 50.
8 is provided, and this fulcrum 58 is connected to the front wheel pivot bar 5.
It is pivoted to 9. Therefore, the steering lever 30 can pivot around this fulcrum 58 in a pendulum shape. For example, when the pin 48 of the fourth gear 46 starts to rotate clockwise as shown by the arrow from the position shown in the drawing, the steering lever 30 will move around the fulcrum 58 and the lower part will move diagonally to the right. Move (in the direction indicated by symbol L).
Therefore, since the connecting lever 54 moves to the left in the figure, the front wheels 15 and 16 lean to the left as shown by dotted lines in the figure, causing the miniature car to turn left. In this left turn operation, pin 48 is exactly 1/4
It is designed to end when the steering lever 30 rotates, and the position of the lower part of the steering lever 30 at that time is shown by a broken line (on the right side). During the left turn operation of the lever 30, the left turn side switch contact 28L of the switch portion 28 is turned ON once, and then the left analysis operation is completed. In other words, the operation of this switch is OFF-
It means performing a series of ON-OFF operations once.

Further, as described above, this steering lever 30 is made of a conductive material, for example, phosphor steel, and this lever 30 and each switch contact 28L
A series of switch operations are performed by contact with 28R and 28R. Therefore, this lever 30 is connected to the electronic circuit section 24 by a cable (not shown).

Next, when the fourth gear 46 rotates another 1/4, the switch section 2 shifts from the previous left turn operating point (dashed line on the right).
It will return to the center of 8. In this operation, similarly, OFF-ON-OFF operation is performed once. When this operation is completed, the lever 30 returns to the straight forward position S again.

Furthermore, in the next 1/4 rotation, the opposite right turn operation is performed, and the lever 30 and right turn side switch contact 28R
A series of switch operations (OFF-ON-OFF) will be performed. Thereafter, similar switch operations and direction change operations will be performed.

Next, a series of operations of the embodiment will be described with reference to the circuit diagram in FIG.

First, to briefly explain the circuit configuration, for example,
A sensor unit 100 consisting of a sound collection unit 14 using an omnidirectional microphone and an amplifier 62 that amplifies the audio signal received from the sound collection unit 14 to a predetermined level.
will be established. It is composed of an electronic switch section 110 that excites the solenoid coil 26 by the output pulse from the sensor section 100, and a mechanical switch section 120 connected in parallel with the electronic switch section 110. As this electronic switch section, a thyristor 64 is adopted,
The mechanical switch 120 includes the aforementioned switch section 28.
(28L and 28R) and steering lever 30
It is composed of. Also, as mentioned above,
A drive (travel) motor 34 is connected to the power source 22.
and the electronic circuit section of the direction changing device of the present invention are in a parallel relationship and share one power source 22. However, the main switch is omitted.

Next, the operation will be explained.

First, the rear wheel drive motor 34 is energized by the power source 22, but the solenoid coil 26 and the thyristor 64 (electronic switch 110) are in an OFF state. Furthermore, it is assumed that the mechanical interlocking (mechanical) switch 28 (mechanical switch 120) is also OFF, and therefore the wheels are moving straight. When a sound is generated by a remote control transmitter (not shown), it is received by the sound collecting section 14 of the sensor section 100, and is amplified by the amplifier 62 to generate a trigger pulse signal for the gate of the thyristor 64. . This trigger pulse signal turns the thyristor 64 into an ON (normal) state, and the solenoid coil 26 is excited. This solenoid coil 26
Due to the excitation of
As a result, the first gear 38 (crank gear) fixed to the drive rear wheel shaft 32 meshes with the second gear 42 (pinion) fixed to the connecting rod 40. As a result, this interlocking rod 40 rotates in a predetermined direction, and a third gear (worm gear) 44 provided on the side opposite to this second gear 42
is the fourth pin engaged with the steering lever 30.
Since it meshes with the gear (gear with crank) 46, this also begins to rotate. As a result, the steering lever 30 is centered around the fulcrum 58.
It begins to rotate in a predetermined direction, for example, clockwise (left turn). Due to this rotation, the tip contact point of the steering lever 30 comes into contact with the contact point 28L of the (mechanical) switch 28 placed opposite thereto, and the circuit is closed.
The (mechanical) switch 28 replaces the thyristor 64, which has been turned off, to continue the operation. Therefore, the rotation of the steering lever 30 continues,
Eventually, the tip contact comes off to the right of the contact 28L, so the (mechanical) switch 28 becomes open (OFF). This opening operation ends the energization of the solenoid coil 26, so the interlocking rod 40 moves to its original position, and the second gear 42 fixed to the interlocking rod 40 transfers to the second gear 42 fixed to the drive rear wheel shaft 32. Disengage from 1st gear 38 and turn steering lever 3
Since the rotation of 0 is stopped, the right turn operation is completed.

By giving a beep from the remote control transmitter again, the thyristor 64 is turned on, the solenoid coil 26 is energized, and the steering lever 30 is turned on.
rotates in the opposite direction to that described above, so the front wheels 15, 1
Turn 6 from left to straight. As a result, the contact point of the steering lever 30 is switched to the switch 28.
The steering lever 3
0 continues to rotate, and eventually the tip contact (mechanical)
Disconnected from contact 28L of switch 28 (mechanical)
Open the switch 28. As a result, the excitation of the solenoid coil 26 is terminated, so that the steering lever 30 faces in a straight direction toward the center S.

At the next transmission, the solenoid coil 26 is energized by the thyristor 64, so the steering lever 30 is rotated to the left, causing the wheels 15 and 16 to change from straight to left turning direction, and the tip contact to be separated from the contact 28R. Solenoid coil 2
6, the direction of the steering lever 30 is changed to the left turn direction.

In this way, the traveling toy 10 is configured such that the (electronic) switch 1 is activated during one type of direction change operation (for example, during a left turn operation).
10 operates ON-OFF, whereas (mechanical)
The switch 120 performs OFF-ON-OFF operation.

As detailed above, the present invention combines a sensor section, an electronic switch, and a mechanical switch using a steering lever, and for example, a solenoid coil is interposed between the electronic switch and the mechanical switch, and the solenoid coil The steering lever is intermittently actuated by the excitation of the steering wheel, thereby providing a direction changing function. Therefore, first of all, it is possible to achieve ultra-miniaturization, and it is also possible to play driving games by remote control on a desk, which is an effect that could not be realized in the past.

Furthermore, it can be made extremely low cost and robust. Furthermore, there is an advantage that even if a low power of, for example, 3V is used as a power source, running performance with a change of direction can be obtained. The circuit configuration is resistant to noise when starting and stopping the motor, so there is no malfunction and there is no need for a complicated noise killer circuit. In addition, since the same power source can serve both the drive side and the conversion mechanism side, the power source can be made smaller, lighter, and more inexpensive.

Note that the present invention is not limited to the embodiments described above, and various changes can be made.

For example, the entire vehicle may have a scooter structure with a single front wheel, or a track pillar may be installed between the front and rear wheels to form a tank, and the vehicle is of course not limited to the automobile described in the embodiment. Further, in the embodiment, the second gear 42 can be intermittently engaged with the first gear 38, but the solenoid coil 26 is positioned on the third gear 44 side, and the third gear 44 is connected to the fourth gear 46.
It may also be possible to engage intermittently with each other. Further, it is preferable to use a coil spring as the front wheel operating pin 56 because it enhances the operating effect due to elasticity. Furthermore, the first
It is convenient to increase the diameter of the gear 38 and the fourth gear 46 to reduce the speed and use it in a tank or the like. Moreover, the reverse is also possible.

Further, although the remote control transmitter is one that generates sound, the present invention is not limited to this, and the transmitter can be made into a push-button type that can be operated with one hand using, for example, radio waves. (Mechanical) switch 28 of 28
A contactless switch can be realized by arranging a reed switch in place of R and 28L and attaching an excitation to the tip of the steering lever 30. Also, instead of the thyristor, an equivalent switch can be constructed using other suitable electronic elements or circuits. (e.g. flip-flop circuit). Finally, as can be easily inferred from the gist of the present invention,
Since the direction can be changed by rotating the fourth gear 46 intermittently, the following modifications can be considered.

That is, without using the solenoid coil 26,
A small motor is provided. This motor is for direction change control and is provided separately from the rear wheel drive motor 34, and the thyristor 64 is operated by excitation in exactly the same way as the solenoid coil 26 by the mechanical switch 28. The rotational force is transmitted to the fourth gear 46 through an appropriate gear (worm gear).
The operating principle of the present invention can be carried out by rotating intermittently.

This modification allows for further miniaturization, and in this case, the interlocking rod 40, first and second gears, solenoid coils, etc. can be omitted, which has the advantage of reducing weight. Furthermore, it can be seen that the control motor may be a small, inexpensive motor with lower output than the drive motor.

Furthermore, the number of mechanical parts is reduced, and assembly and adjustment are extremely simple.
