Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a remote control device that facilitates the forward and backward movement and course change of a model vehicle such as a model car.

[Background of the idea]

Conventionally, this type of remote control device, regardless of whether it is wireless or wired, has a lever for forward and reverse movement and a lever for steering on the control panel, and the operator holds the control panel with both hands and operates both levers with the left and right thumbs. Many of them are designed to operate moving objects such as model cars. Therefore, in order to change the course while moving the model vehicle, it is necessary to operate the thumbs of both hands, and in particular, when maneuvering in a narrow space, the operation of the thumbs of both hands becomes busy.
It was difficult for children to operate. Also, since the thumbs of both hands are occupied when operating the lever,
It was almost impossible to perform other operations, such as sounding the horn, while piloting the aircraft.

[Purpose of invention]

In view of the above points, this idea was developed to make it possible to easily move the model vehicle forward or backward and change its course, and also to enable other operations such as sounding the horn or changing speed while operating the model vehicle. The purpose is to provide a control device.

[Structure of the idea]

In order to achieve the above objective, this invention was developed to create a model car that is equipped with a drive switch that switches between forward and reverse rotation of the drive motor that moves the drive wheels forward and backward, and a steering switch that switches the steered wheels left and right on the control panel. In the remote control device, a pendulum body facing in the direction of gravity, which has a rib for bringing a movable contact piece into contact with either the fixed contact piece for left steering or the fixed contact piece for right steering of the steering switch, is arranged in a certain range. Rotatably installed,
It is constructed so that the steering wheels can be switched left and right by simply tilting the operation panel left and right while moving the model traveling body forward and backward.

〔Example〕

Next, this invention will be explained based on embodiments shown in the accompanying drawings.

In the figure, reference numeral 1 denotes a model traveling body main body (hereinafter simply referred to as the main body), and the main body 1 has drive wheels 2 at the rear thereof,
2' to travel in the front and rear direction, and the front steering wheels 3,
3' allows you to change course to the left or right.

The drive wheels 2, 2' are fixed to both ends of a drive shaft 5 which is connected to the output shaft of a drive motor 4 mounted in the main body 1 via a speed reduction mechanism (not shown).

The steering wheels 3, 3' are rotatably supported on the distal ends of swing shafts 6, 6' whose base ends are supported horizontally at symmetrical positions on the main body 1 so as to be swingable in the horizontal direction.
The swing shafts 6, 6' are pivotally supported at both ends of a crossbar 8 with the tips of protruding rods 7, 7' provided integrally with the shafts.
The orientation of the steering wheels 3, 3' is stably maintained.
This crossing rod 8 is a steering motor 9 mounted on the main body 1.
It is connected via a pin 12 to a long hole 11 at the tip of a lever 10 whose base end is fixed to an output shaft 9'. Therefore, the transfer rod 8 is slid by the lever 10, which is rotated to the left or right by the output shaft 9' of the steering motor 9, and controls the steering wheels 3, 3' via the swing shafts 6, 6'. Turn to the right or left.

Reference numeral 13 denotes an operation panel of the main body 1, and the operation panel 13 consists of a battery box section 14 and a circular handle section 15. This circular handle part 15 is integrally attached to a central part 151 fixed to the upper surface of the battery box part 14 via three radial stays 152A to 152C, and the whole is a hollow body divided into an upper half and a lower half. It's summery. And one stay 1
A main switch 16 is provided on the upper surface of 52A, and when the stay 152A provided with the switch 16 is directed toward the operator, the stay 152B, which is on the right hand side of the operator, is connected to the drive motor 4 in the main body 1. Two push button switches 1 for switching between forward and reverse directions
7, 17' are provided. One push button switch 17 energizes the drive motor 4 so as to rotate the main body 1 in the forward direction, and the other push button switch 17' energizes the drive motor 4 so as to rotate the main body 1 in the reverse direction. It is something. That is, when the push button switch 17 is pressed, the first movable contact piece 171 connected to the negative side of the battery 141 is separated, as shown by the symbol _S1 in FIG. It is connected to the positive side of the battery 141, and when the push button switch 17' is pressed, the second movable contact piece 171', which was connected to the negative side of the battery 141, is separated and connected to the positive side of the battery 141. It's summery.

Further, the stay 152C on the left hand side of the operator is provided with a push button switch 19 for sounding a buzzer (klaxon) 18 incorporated in the battery box section 14, and a push button switch 19' for changing the speed. This speed change can be done, for example, by storing three 1.5V batteries in the battery box 14,
to drive the drive motor 4, and press the push button switch 1.
Even if you want to be able to drive the drive motor 4 with 4.5V when pushbutton switch 19' is pressed, install a resistor in the middle of the circuit so that when pushbutton switch 19' is pushed, the voltage will not go through the resistor and will be applied to the drive motor 4. It may be possible to directly supply electricity, or it may be carried out by other means.

Furthermore, a switch 20 is provided in the central portion 151 of the circular handle portion 15 for switching the output shaft 9' of the steering motor 9 mounted in the main body 1 between forward and reverse directions. This switch 20 has a circular handle portion 15 that is held by the operator with both hands around a support shaft 201.
A pendulum body 202 is provided for bringing the movable contact piece into contact with the fixed contact piece for right steering when tilted to the right, and with the fixed contact piece for left steering when tilted to the left. This pendulum body 202 faces the direction of gravity, and on its lower surface there are ribs 20 that open outward in a symmetrical position across the support shaft 201 in a V-shape.
3,204 are provided, and these ribs 203,204
The tips of the movable contact pieces 205 and 206 face in the middle, as shown by the reference numeral _S2 in FIG. Further, the rotation range of the pendulum body is determined by an arc-shaped long hole provided in the pendulum body itself and a pin protruding from the operation panel side, and is regulated so that it does not swing or rotate beyond a necessary angle. . Therefore, when the pendulum body 202 swings around the support shaft 201, the movable contact piece 20
5, 206 is bent, and the fixed contact piece 205A or 20 faces the left movable contact piece 205 with this in between.
5B, and similarly the right movable contact piece 206
This is connected to one of the fixed contact pieces 206A or 206B facing each other with this in between. For example, when the pendulum body 202 swings to the right (in the R direction), the left movable contact piece 205 connects to the fixed contact piece 205B, and the right movable contact piece 206 connects to the fixed contact piece 206A. As a result, the steering motor 9 operates to turn the steered wheels 3, 3' to the right. On the contrary, the pendulum body 202 is on the left (L direction)
When swinging, the left movable contact piece 205 is connected to the fixed contact piece 205A, the right movable contact piece 206 is connected to the fixed contact piece 206B, and the steering motor 9 turns the steering wheels 3, 3' to the left. It will now work like this.

Next, the operating method of the above embodiment will be explained.

First, hold the circular handle portion 15 with both hands so that the stay 152A provided with the operator's main switch 16 is in front of you. Then, when the main switch 16 is turned on and one of the push button switches 17 and 17' provided on the stay 152B on the right hand side is pressed with the right thumb, the main body 1 moves forward or backward. When the operator tilts the circular handle 15 to the right or left during this forward or backward movement, the pendulum body 202 swings to the right or left in response, and as described above, the steering wheels 3, 3' are moved in the tilted direction. You can change your course towards.

During this maneuver, press button switch 19 or 1 with your left hand.
By pressing 9', you can sound the buzzer while driving and increase the speed, giving you the feeling of actually driving a car.

In the above embodiment, the main body 1 and the operation panel 13 are connected by wire, but it is also possible to install an oscillator on the operation panel and a receiver on the main body to enable wireless control. Even in the case of a wired system, it is possible to use a connector to connect to a plurality of traveling bodies with one operation panel as shown in FIG.

Further, in the above embodiment, the switches are provided on each of the three stays of the circular handle portion, but the positions where the switches are installed are not limited to this example, and the number of stays does not need to be limited to three. In addition, although a model car is illustrated as a running object, it is not limited to this, and may include a model airplane or other objects (such as animal toys).
Of course, it may be.

Furthermore, in the above embodiment, the buzzer and speed change are performed with the left hand, but a light may be turned on, or the buzzer, speed change, and light may be operated simultaneously or selectively. Of course, if the vehicle is an ambulance or a police car, a siren and revolving lights may be activated.

[Effect of idea]

As explained above, this idea is based on the remote control of a model running body, which is equipped with a drive switch for switching between forward and reverse rotation of the drive motor that moves the drive wheels forward and backward, and a steering switch for switching the steered wheels left and right on the control panel. In the steering device, a pendulum body facing in the direction of gravity is rotatable within a certain range, and has a rib for bringing a movable contact piece into contact with either the fixed contact piece for left steering or the fixed contact piece for right steering of the steering switch. Since the vehicle is equipped with a switch, it is possible to change the course of the vehicle by simply tilting the control panel to the right or left while the vehicle is traveling by operating a switch, making it easy to move forward and backward and change the course. This not only has the advantage of being easy to handle even for children, but also allows the user to perform actions other than steering while the vehicle is running with the other hand that is not used to change the course of the vehicle.

Further, in this invention, when the operating panel is shaped like a circular handle, there is an advantage that the driver can feel as if he or she is actually driving a car.
