Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a radio control device used to remotely control models such as model airplanes and model helicopters, and to remotely control various industrial equipment. , particularly regarding its transmitter.

[Prior art]

Conventionally, radio control devices have been used as devices for remotely controlling controlled objects such as model airplanes and model helicopters. This radio control device includes a transmitter that transmits radio waves to a controlled object according to the operating state of an operating member, and a receiver that is mounted on the controlled object and receives radio waves from the transmitter.
It consists of an operating section such as a servo device that operates the movable part of the steered object based on the received signal from the receiver.

In addition, especially in radio control devices used for models, the models are required to have motion performance equal to or better than that of the real thing, so improvements in operability and functionality are being made. Generally, most of the movable parts of the model are connected to a servo device by rods or the like, and are operated by rotating the servo device from side to side. For this reason, improving the functionality and operability of radio control devices means increasing the number of main operating members in the transmitter that basically operate the operating parts of these servo devices, etc., and expanding and expanding the movement of the main operating members. Progress is being made with a focus on expanding the number of auxiliary operating members that can be changed.

The auxiliary operating member may have a reverse function that reverses the movement of the servo device relative to the movement of the main operating member, or a function that allows the operating range of the servo device to be changed relative to the main operating member without changing the neutral position. There are some that have various functions, such as those that have a mixing function that interlocks two servo devices with one main operating member. If the movement of the servo device could be reversed or its operating width could be changed, it would be useful when incorporating the servo device into a controlled object such as a model airplane and connecting it to the movable parts of the controlled object via a rod, etc., or when the transmitter. Adjusting the movement of the movable part of the steered object with respect to the movement of the main operating member is extremely easy.
Furthermore, in model airplanes, elevators and flaps, or engine controls and propeller pitches are linked using a mixing function,
In a model helicopter, flight performance and flight maneuverability are improved by interlocking the pitch of the main rotor and the pitch of the tail rotor using a mixing function in order to cancel the counter torque generated by the rotation of the main rotor. I can do it.

An example of a transmitter of such a multi-functional radio control device is shown in FIG. 4 below.

FIG. 4a is a perspective view showing an example of a transmitter for a model helicopter, and FIG. 4b shows an operation panel disposed on the back of this transmitter.

This transmitter 1 consists of a transmitter main body 2, which is equipped with a transmitter circuit and a power supply for forming control signals in accordance with the movements of each operating member, and transmitting the control signals on radio waves, and an open girval mechanism. Therefore, it has a movable main operation member consisting of a pair of stick levers 3a, 3b and switches, which have an automatic return function except for a part, and various other auxiliary operation members. In more detail, each stick lever 3
a and 3b are rotatable vertically and horizontally, and each
Each channel is a total of 4 channels, that is, operating parts such as servo devices can be operated at 4 locations. Generally, these stem levers 3a and 3b are used to control the engine and aileron of a model helicopter.
It operates each movable part of the elevator and rudder. Further, as auxiliary operating members, the stew lever 3a is provided with trim levers 4a and 4b, and the stew lever 3b is provided with trim levers 4c and 4d, respectively, to finely adjust the electrical neutral position of the stew levers 3a and 3b. .
5 is a power switch, and 6 is a transmitting antenna. Furthermore, 7a to 7d are the stem levers 3.
Similar to a and 3b, this is an auxiliary switch or volume as a main operating member. In addition, 8a to 8c are switches for changing the operating width of the servo device to a preset value for a specific main operating member (the operating width of the servo device can be freely changed within a fixed operating range). ) and forms part of the auxiliary operating member. In addition, the auxiliary operation members 9 and 10 include switches and volume controls for operating the servo device to a preset state or stopping the movement of the servo device for a specific main operation member. There is.

On the other hand, an operation panel 11 is formed on the back side of the transmitter 1, and has auxiliary operation members A to F such as a dip switch and a polyurethane. When the auxiliary operation member 8c is activated, the auxiliary operation member A adjusts the operating range of the servo device in response to the left-right operation of the stem lever 3a (the aileron operation in the model) by rotating the volume a. It is something. The auxiliary operation member B is a pitch-related adjustment volume that operates on the auxiliary volume 7b and the like to change the amount of pitch displacement of the main rotor of the model helicopter. Further, the auxiliary operation member C operates on the auxiliary operation members 9 and 10, and stops the movement of the servo device at a predetermined position in response to the vertical operation of the stick lever 3a (engine control operation in the model). In this case, there is a volume or switch to adjust the stop position. And the auxiliary operation members D and E are
Each operates on the auxiliary operation members 8a and 8b, and corresponds to the operation of the steering lever 3b in the vertical and horizontal directions (elevator and rudder operations in the model).
It has a volume that can change the operating width of the servo device within a fixed operating range, and a volume that switches the mixing function between activation and non-operation and adjusts the amount thereof. Further, the auxiliary operation member F is a reverse switch of the servo device in all the main operation members.

In addition, the operation panel 11 has a fail-safe function that moves all servo devices to a neutral position or a preset position when external noise is received, and a hold function that uses the previous signal as the operating signal when external noise is received. have.

By the way, when operating various models, it is preferable to use a dedicated radio control device developed for model cars and model airplanes for each model, but except in special cases, it is best to use a dedicated radio control device for each model. You can operate a model as long as you have the necessary number of channels (number of main operating parts) to operate it (2 channels for a car, at least 4 channels for an airplane or helicopter). In addition, since radio control devices with multi-functions are particularly expensive, only the devices that are mounted on the model as a controlled object, such as receivers and servo devices, are prepared for each model, and the transmitter is It is also being used for several models.

[Problem that the invention seeks to solve]

By the way, in the transmitter of the radio control device which has multiple functions as shown in FIGS. Alternatively, the position of the volume that adjusts the rotation angle of the servo device is unique to each model, and must be adjusted for each model, not only when the type of model changes, but even when operating the same type of model. There is a need. Some of these adjustments can be made while looking at the moving parts of the model without actually operating the model, but finer adjustments must be made many times while operating the model. Not only when a transmitter that has been adjusted for one model is to be used as a transmitter for another model, but also when trying to operate a model that has been previously adjusted, adjustments must be made from the beginning. However, there was a problem in that the adjustment work was complicated and took time. As a result, there was a problem in that it was difficult to use the same transmitter.

[Means for solving problems]

The present invention has been made in view of the above-mentioned problems, and provides a transmitter for a radio control device that can easily reproduce the auxiliary operating member of the transmitter into a preset operating state according to the non-controlled object to be controlled. The purpose is to provide

In order to achieve the above-mentioned object, the configuration of the present invention is as follows: ``Radio waves are transmitted from a transmitter by an operator's operation, and these radio waves are received by a receiver mounted on a piloted object. In the transmitter of the radio control device used to operate the movable members of the control object and remotely control the control object, the main operation member for controlling the control object and the control characteristics of the main operation member are expanded and It consists of a transmitter body that has an auxiliary operation member for changing the transmitter body, and a gauge panel that is removably attached to the transmitter body and is provided with a gauge that indicates the operation position of the auxiliary operation member. .

[Effect]

When operating multiple models or other controlled objects using one transmitter, prepare as many gauge panels as the number of controlled objects in advance, and perform auxiliary operation of the transmitter once for each controlled object. By adjusting the members and indicating their operating positions using the gauges on the gauge panel, it is possible to know from the gauges on the gauge panel which position the auxiliary operating section of the transmitter should be aligned with respect to the steered object.

The depth switch 26 is a switch that reverses the movement of an operating section such as a servo device mounted on the controlled object in response to the movement of various main operating members. Depth switches 27a and 27b are switches for selecting functions of the transmitter 20 according to the controlled object, and by changing the setting positions of these switches, the effect of the volume 28 is changed. That is, by using the volume 28 in combination, the number of volumes 28 is reduced and the configuration is simplified.

Reference numeral 29 denotes a transparent or translucent gauge panel, which is an important part of the present invention, and has gauges 30 and 31 that indicate the operating positions of each volume 28 and depth switches 26, 27a, and 27b.

Furthermore, although not shown, the gauge panel 29 has a claw that engages with the case 21 at one end, and a protrusion that is press-fitted into a hole formed in the case 21 at the other end. Then, the gauge panel 29 is attached to the case 21 by engaging the claw at one end with the case 21 and press-fitting the protrusion at the other end. Note that there is a case 21 or a sheet 32 near the protrusion of the gauge panel 29.
If a gap is provided, the gauge panel 29 can be easily removed from the case 21 by hand by hooking a nail into this area.

Next, the use of the gauges 30 and 31 will be explained. First, a seat 32 (for example, for a model airplane) is prepared according to the type of object to be operated, and a gauge panel 29 to which gauges 30 and 31 are attached is attached to the case 21. Before actually operating the robot together with other auxiliary operating members such as auxiliary operating members 25a and 25b, the movement of each movable member of the controlled object is checked, and the depth switches 26 and 2 are checked.

In particular, for parts that rarely need to be adjusted once adjusted for each controlled object, such as the reverse depth switch of a servo device, a sticker 41 is affixed to the gauge panel 29 to mark its position as shown in Figure 3c. Any shape may be used as long as the operating position of the auxiliary operating member can be determined, such as by placing a pin in a gauge panel to indicate the position.

Further, although the gauge panel was used only for some of the auxiliary operation members in the previous embodiment, the gauge panel may be used for all the auxiliary operation members, or for other auxiliary operation members such as the trim levers 23a and 23b in FIG. It may also be provided on the auxiliary operating member.
