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 running direction etc. by changing the duty ratio of the pulse width modulation (PWM) method.

However, with such known remote control direction changing devices, 1) the entire device becomes large, 2) it is necessary to separately provide a power source for traveling (drive) and a power source for traveling control, and the cost is relatively high. Voltage, e.g. 9■~1
Since a power supply capable of supplying 2V is required, the volume occupied by the power supply increases; 3) A large number of primary or secondary batteries are required for these power supplies, increasing costs; 4) Servo - Direction changing devices using 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. Various disadvantages. was there.

The present invention solves the above-mentioned drawbacks, and in particular reduces the size, cost, and
The purpose of this paper is to propose a direction change device for remotely controlled running toys that has low voltage, low power consumption, and a simple structure.

The direction change in the remotely 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 switching device that uses the gate signal from this sensor section. Between an electronic switch that operates, a mechanical switch that is connected in parallel with the electronic switch and that performs a switching operation by turning the steering lever that controls the direction of travel, and a parallel circuit of these electronic and mechanical switches and a power source. and a running direction switching means connected in series to the steering lever for rotating the steering lever, the electronic switch and the mechanical switch are switched and actuated, and the running direction switching means rotates the steering lever. It is characterized by the fact that the operation is performed intermittently.

The present invention will be explained below with reference to one drawing.

FIG. 1 is a perspective view of a miniature car incorporating a direction changing device in a remotely controlled traveling toy of the present invention. IO is the body of a miniature car, and this body IO is removably attached to a chassis (not shown) on which a conversion device to be described later and the functional parts of the original automobile are mounted. This car body 1
A sound collecting section 14 for receiving sound waves for remote control is disposed on the roof section 12 of the vehicle.

FIG. 2 is a plan view of the vehicle body 10 removed from the bottom portion 20. Front wheel 15.1B is at the top of the drawing, rear wheel 17.1
8 are respectively received at the bottom, the front wheels 15.18 are for direction change, and the rear wheels 17.18 are for drive.

First, the electrical system configuration of the direction changing device of the present invention will be described. Reference numeral 22 is a power supply section, and in this example, 3V is obtained by connecting two AA size ultra-small dry batteries and other two in series. As will be described later, this power source is a 0-order power source that is commonly used for the drive (travel) of the automobile and the power source for the direction change device.
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 collection section 14 and solenoid coil 2B are also connected to the electronic circuit section 24, but the connection cable is not shown for simplicity. Finally, the switch section 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 i
These connection cables are also omitted.

Next, the mechanical configuration of the direction changing device of the present invention will be explained. First, the rear wheels 17 and 18, which are drive shafts, are about to be mounted on the axle 32. In order to transmit rotational force to this axle 32, a motor 34j is linked via a drive-side gear group 38.

A first gear 38 is attached to this axle 32 on the side opposite to the drive side gear group 3B. On the other hand, the solenoid coil 26
A through hole is formed near the top of the suction shaft 27, and the interlocking rod 40 is communicated within this through hole. A second gear 42 (bini pin) that meshes with the first gear 38 (cluster, run gear) described above is attached to one end of this interlocking rod 40, and a third gear 44 for operating the steering lever 30 is attached to the other end. (worm gear) is installed. This interlocking rod 40 is connected to the second
The gear 42 is arranged 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. 2 (on the right side in the drawing).
exists, the meshing state is released, and during excitation, the meshing state is formed by being located on the left side.

On the other hand, the third gear 44 at the other end of the interlocking rod 40 is always in mesh with a fourth gear 48 (gear with a crank). This fourth gear 4B has a disk shape, and teeth are carved on the peripheral edge thereof. A pin 48 is implanted on one plane of the fourth gear 4B, and the pin 48 is loosely fitted into the guide groove 50 of the steering lever 30. Further, this steering lever 30 has a notch groove 52 formed at its tip (upper part of the drawing), and a connecting bar 54 for the front wheels 15 and 16 is formed in the notch groove 52.
, is engaged with pin 58. Furthermore, a fulcrum 58 is provided between this notch groove 52 and the guide groove 50, and this fulcrum 58 is pivotally connected to a front wheel pivot bar 59. Therefore, the steering lever 30 is designed to be able to rotate in a pendulum shape around this fulcrum 58.
When the pin 48 of the gear 4B starts to rotate clockwise as shown by the arrow from the position shown in the drawing, the lower part of the steering lever 30 moves diagonally to the right about the fulcrum 58 (as indicated by the symbol Therefore, this miniature car will make a left turn. This left turn operation is designed to end when the bin 48 has made exactly 1/4 turn, and the steering lever 30 at that time is The position of the lower part is indicated by a broken line (on the right). This is <
During the left turn operation of -30, the left turn side switch contact 28L of the switch section 28 is turned ON once, and then the left turn operation is completed. In other words, the operation of this switch is
・0FF-ON-OF until 8 rotates 1/4
This means performing the series of operations F once.

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

Next, when the fourth gear 46 rotates one more gear, it returns to the center of the switch section 28 from the left-turn operation point (broken line on the right). This operation 41, similarly, 0FF-ON
The -OFF operation is performed once. When this operation is completed, the lever '-3' (returns to the S straight position).

Furthermore, in the next 1/4 rotation, the opposite right turn operation is performed, and a series of switch operations (OFF-ON-OFF) are performed between the lever 30 and the right-turn side switch contact 28R. 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 shown in FIG.

First, to briefly explain the circuit configuration, for example, the sound collecting section 14 using an omnidirectional microphone and the sound collecting section 14
A sensor unit 100 is provided which includes an amplifier B2 that amplifies the audio signal received from the audio signal to a predetermined level. This sensor part 1
Solenoid coil 28 due to the output from 00
It is composed of an electronic switch section 110 that excites the electronic switch section 110, and a mechanical switch section 120 that is connected in parallel with the electronic switch section 110. As this electronic switch section, a thyristor 64 is adopted, and the mechanical switch 120 is the above-mentioned switch section 28 (28L).
28R) and the steering lever 30. Further, as described above, the drive (travel) motor 34 and the electronic circuit section of the direction changing device of the present invention are in a parallel relationship with respect to the power source 22, 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, and the solenoid coil 2B and thyristor 64 (
The electronic switch 110) is in the 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 the sound 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 thyristor 64 is energized.

By energizing the solenoid coil 26, the interlocking rod 40 is displaced from its front position, that is, attracted to the coil side).

Therefore, the first gear 38 (crank gear) fixed to the drive rear wheel shaft 32 is connected to the second gear 42 (crank gear) fixed to the connecting rod 40.
pinions) will start to engage. As a result, this interlocking rod 40 rotates in a predetermined direction, and this second
A third gear (worm gear) 44 provided on the side opposite to the gear 42 is a fourth gear pin-engaged with the steering lever 30.
Since it meshes with gear (gear with crank) 4B, this will also rotate. As a result, the steering lever 30 begins to rotate about the fulcrum 58 in a predetermined direction, for example, clockwise (left turn).

This rotation causes the tip contact portion of the steering lever 30 to close (ON) the contact point 28L of the (mechanical) switch 28 disposed opposite to it.
Due to the closing of the (mechanical) switch 28, the previously applied voltage of the thyrist 64 becomes zero (41 mechanical switch 28 short circuit), and at the same time the excitation of the solenoid coil 26 is reduced to this (mechanical) ) via the switch 28, so the energization of the solenoid coil 26 continues. Therefore, since the rotation of the steering lever 30 continues, the (mechanical) switch 28 is again released (“0FF”). This release operation ends the energization of the solenoid coil 26, so the interlocking rod 40 is moved to the original position, the second gear fixed to the moving rod is disengaged from the first gear 3B fixed to the driving rear wheel shaft 32, and the rotation of the steering lever 30 is stopped, so that the left turn operation is not performed. Completed.Once again, by giving a beep from the remote control transmitter, the thyristor 64 is turned on, the solenoid coil 26 is energized, and the fourth gear 46 is rotated, but this time the steering lever 30 is moved in the opposite direction from the above. Therefore, the front wheels perform the same operation as described above while changing the direction from left turn to straight forward direction, that is, the (mechanical) switch 28 is turned ON and then released, and then the steering lever 30 is turned. The zero-order beep that stops at the center (S) now causes a direction change to turn right.In other words, during one type of direction change operation (for example, a left turn operation), the electronic switch 110 is ON-OFF.
while the mechanical switch 120 is 0FF-
It performs 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 both the electronic switch and the mechanical switch, and the solenoid coil is interposed between the electronic switch and the mechanical switch. The steering bar is intermittently actuated by excitation of the coil to provide a direction changing function. Therefore, first of all, it is possible to achieve ultra-miniaturization, and it is also possible to play with remote control on a desk.
It has a profound effect that cannot be achieved conventionally.

Furthermore, it can be made extremely low cost and robust. Also,
``It has the advantage of being able to provide running performance that allows you to freely change direction even if you use a low power supply of about 3V as the power source.It also has a circuit configuration that is resistant to noise when starting and stopping the engine, so there is no malfunction. There is also the advantage that a complicated noise killer circuit is not required.In addition, the same power supply can be used for both the drive side and the conversion mechanism side, making it possible to make the power supply smaller, lighter, and lower in price.

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

For example, the entire body may have a scooter structure with a single front wheel, or a multi-pillar structure 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
position to the third gear 44 side, and move this third gear 44 to the fourth gear.
It is also preferable that the front wheel actuating pin 56 be made of a coil spring so as to enhance the operating effect due to elasticity. Furthermore, the first gear 38
It is convenient to increase the diameter of the fourth gear 46 and reduce the speed for use in tanks, etc., and vice versa.

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

That is, a small motor is provided without using the solenoid coil 26. This motor is for direction change control and is provided separately from the rear wheel drive motor 34.
The operating principle of the present invention can be carried out by causing the fourth gear 46 to rotate intermittently through an appropriate gear (worm gear) by using the rotational force of the fourth gear 46 through the same excitation operation. .

This modification allows for further miniaturization, and in this case there is an advantage that the interlocking rod 40, first and second gears, solenoid coils, etc. can be omitted, resulting in weight reduction. Also,
It can be seen that this control motor can be a small, inexpensive motor with a lower output than the drive motor.

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