Utility Model Publication No. 6-31232

However, in the transmitter of a conventional radio control device, the high frequency module for control can be replaced, but in what configuration can the wireless communication module for communicating a communication signal different from the control signal be replaced? There is no suggestion.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a radio control transmitter that can be detachably provided with a wireless communication module for communicating communication signals different from control signals. .

Next, means for solving the above problems will be described with reference to drawings corresponding to embodiments.
The radio control transmitter according to claim 1 of the present invention includes a grip portion 3;
a head section 5 that is provided at one end of the grip section 3 and has a communication module that outputs a control signal and a control antenna 11;
a base portion formed with a larger diameter than the grip portion 3 and provided at the other end of the grip portion 3, housing the battery 12 and supporting the grip portion 3, with a rear portion 13 on the wrist side and a front portion 14 on the finger side; 4 and
a connector 20 provided on the front portion 14 of the base portion 4;
In addition to being equipped with
The present invention is characterized in that it has a wireless communication module 15 which is connected to the connector 20 so as to be freely coupled/uncoupled and transmits/receives a communication signal different from the control signal .

In this radio control transmitter, a base portion 4 is provided at the other end of the grip portion 3, and a connector 20 is provided on this base portion 4. An arbitrary module such as a wireless communication module 15 that transmits and receives communication signals different from control signals can be connected to the connector 20, for example. The grip part 3 becomes heavy at the bottom because the battery 12 is housed in the base part 4. By making the grip part 3 heavier on the base part 4 side, the balance is improved when positioning. Replaceable modules such as the wireless communication module 15 are arranged on this base portion 4 . This allows heavy items to be collected in the lower half, resulting in better positioning balance without deterioration.
Furthermore, since the base section 4 houses the battery 12, which is relatively large and heavy among the mounted components, it is easier to secure empty space compared to the lightweight head section 5. This empty space can be effectively utilized to arrange the connector 20, and can easily be secured as a space for mounting the module. Further, when the module connected to the connector 20 is the wireless communication module 15, the radio control transmitter includes the head section 5 that outputs the control signal and the wireless communication module 15 that transmits and receives communication signals different from the control signal. However, one end (upper side) and the other end (lower side) of the grip portion 3 are separated from each other. This suppresses competition for radio waves between both antennas. Furthermore, by disposing this wireless communication module 15 at the front part 14 of the base part 4, transmission and reception can be performed better than if it is disposed at the rear part 13, which is closer to the operator's body. Even when the radio control transmitter is held horizontally with the front and back direction parallel to the body, the wireless communication module 15 connected to the connector 20 is provided on the front part 14 of the base part 4. This makes it possible to transmit and receive data better without being affected by the body.

Furthermore, in this radio control transmitter, the wireless communication module 15 connected to the connector 20 enables communication of communication signals other than control signals. Since the wireless communication module 15 can be coupled and uncoupled by the connector 20, it is a module that transmits and receives communication signals different from control signals of various standards, such as Bluetooth (registered trademark) standard and Wi-Fi standard. and exchange is possible. This makes it possible to transfer images, send and receive back-up signals for control, and send and receive over a stable radio wave band without using radio waves from the operation unit.

The radio control transmitter according to claim 2 of the present invention is the radio control transmitter according to claim 1 , comprising:
It is characterized by comprising a cover 16 attached to the front part 14 and covering the connector 20.

Further, when a module is connected to the connector 20, the module is covered and protected.

The radio control transmitter according to claim 3 of the present invention is the radio control transmitter according to claim 2 ,
The cover 16 is characterized in that it has a raised molded part 30 that bulges outwardly opposite to the connector 20.

In this radio control transmitter, a raised molded portion 30 is formed on the cover 16. This raised molding 30 becomes effective when various modules, for example the wireless communication module 15, are connected to the connector 20 and the height of this module changes. That is, in the case of the wireless communication module 15, the circuit section is arranged at the center of the upper surface of the rectangular substrate section 21. The circuit section is connected to a wavy line pattern antenna 24. The circuit section is covered by a case 23. By having the raised molded portion 30, the cover 16 can avoid interference with cases 23 mounted at different heights in various wireless communication modules 15.

According to the radio control transmitter according to claim 1 of the present invention, any module can be connected to the connector provided on the base portion.

Moreover, according to this radio control transmitter, a wireless communication module for communicating a communication signal different from a control signal, for example, a wireless communication module for transmitting and receiving a communication signal different from a control signal, such as a Bluetooth standard or a Wi-Fi standard. It can be provided detachably.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the attached drawings.

The radio control transmitter (hereinafter referred to as transmitter 1) according to the present invention uses, for example, various model bodies (cars, motorcycles, aircraft, ships, etc.) and industrial machines such as cranes as objects to be operated, and uses a predetermined frequency. The transmission frequency is determined by a frequency hopping method that automatically selects an empty band from the frequency band (for example, 2.4 GHz band), and the transmission frequency is determined by the frequency hopping method that automatically selects an empty band from the frequency band. The controlled object is remotely controlled by transmitting control signals (radio waves) corresponding to the operation to the controlled object.
Here, the control signal is a signal emitted when operating and maneuvering the controlled object as described above. In addition, the communication signal described later is a communication signal other than this control signal that is different from the control signal, that is, it is different from the signal (control signal) that is emitted in real time when operating and maneuvering the controlled object. be.

In this example, a case will be explained in which the object to be controlled remotely by the transmitter 1 is a model car. Furthermore, although the description will be made assuming that an engine is used as the power source for the steered object, a motor can also be used as the power source.

FIG. 1 is a perspective view showing the overall configuration of a radio control transmitter according to the present invention.
As shown in FIG. 1, the transmitter 1 is roughly composed of a grip part 3, a base part 4, and a head part 5, and the housing of each part is made of flexible thermoplastic resin (for example, general-purpose plastic). has been done.

The grip part 3 has one end (upper side) integrated with the head part 5 and the other end (lower side) integrated with the base part 4, and has an elliptical columnar outer shape that becomes narrower from the base part 4 toward the head part 5. is formed. The grip section 3 functions as a grip section that is held by the operator when remotely controlling the controlled object.

The base portion 4 is provided at the other end (lower side) of the grip portion 3 and is formed in a rectangular shape. The base part 4 regulates the lower limit position of the hand that grips the grip part 3 to prevent the hand from falling out of the grip part 3, and also prevents the hand from slipping off from the grip part 3. It also functions as a leg with a predetermined installation area on the bottom surface.

Further, the base portion 4 is provided with a switch mechanism 7 that is operated by the operator when operating the wheel 6 or the trigger 2 using both hands. FIG. 1 shows an example in which the switch mechanism 7 is provided at the end on the operator's side when the operator grips the grip part 3. The switch mechanism 7 is designed to prevent the operator from touching a part of the body other than the fingers of both hands (e.g., chest, abdomen, shoulders, thighs, knees, etc.) or nearby objects (e.g., a handrail in a stadium) during two-handed operation. By pulling the transmitter 1 and turning the switch on and off, the function assigned to the switch mechanism 7 can be activated.

The functions assigned to the switch mechanism 7 can be arbitrary, such as turning on/off the turbo function, mixing, gyro operation, lap measurement, sudden braking, camera, etc., but in particular, the functions that the operator wants to operate in parallel while operating with both hands can be assigned. If assigned, the switch mechanism 7 can be instantaneously operated at a moment's notice in an emergency situation, and the functions assigned to the switch mechanism 7 can be turned on and off instantly.

The head portion 5 is provided at one end (upper side) of the grip portion 3 and includes a wheel 6 as a first operating member and a trigger 2 as a second operating member.

FIG. 2 is a cross-sectional side view of the base portion 4 of the radio control transmitter according to the present invention.
The wheel 6 is an operation member serving as a steering wheel for controlling the direction of movement of the steered object. As shown in FIGS. 1 and 2, the wheel 6 extends perpendicularly to the substantially disk-shaped surface in the direction of the head portion 5 of the transmitter 1, with its axis aligned with the center of the substantially disk-shaped surface. supported by an existing rotation axis. The wheel 6 is rotated counterclockwise and clockwise from a predetermined reference position and is operated as a steering wheel for controlling the traveling direction of the steered object.

The trigger 2 is an operating member for controlling the power source of the steered object and controlling the moving speed of the steered object. As shown in FIGS. 1 and 2, the trigger 2 has a trigger shape and is divided into a throttle lever 8 as a first lever and a brake lever 9 as a second lever. It is attached to the head part 5 so as to be rotatable in the directions of arrows A and B.

The trigger 2 is rotatable in the direction of arrow A in FIG. 2 until the throttle lever 8 comes into contact with a contact surface (not shown) of the head section 5, and the brake lever 9 comes into contact with the other end of the head section 5. It is rotatable in the direction of arrow B to a position where it abuts a contact surface (not shown).

The trigger 2 is generally operated by placing the index finger of the hand holding the grip part 3 on the throttle lever 8 and pulling it in the direction of arrow A, and pushing the brake lever 9 with the back of the finger placed on the throttle lever 8 in the direction of arrow B. Be manipulated.

When the trigger 2 is released from the throttle lever 8, the trigger 2 automatically returns to a preset initial position (the state shown in FIG. 2). This initial position is called the neutral position. In the neutral position, the engine of the steered object is rotating, but the clutch is disengaged, and the steered object is not running.

Note that if the power source of the steered object is a motor, the motor is not rotating in the neutral position.

The trigger 2 controls the throttle of the engine of the steered object by pulling the throttle lever 8 in the direction of arrow A in FIG. 2, thereby controlling the moving speed of the steered object. The more the trigger 2 operates the throttle lever 8 in the direction of arrow A, the more the steered object accelerates.

Further, the trigger 2 can be configured to control the brake by operating the brake lever 9 in the direction of arrow B in FIG. The trigger 2 becomes a stronger brake as the brake lever 9 is operated in the direction of arrow B.

Note that, depending on the settings of the transmitter 1, operating the brake lever 9 of the trigger 2 in the direction of arrow B in FIG. 2 may cause the steered object to move backward. Furthermore, even when a motor is used to power the steered object, the steered object can be accelerated by operating the throttle lever 8 of the trigger 2 in the direction of arrow A in FIG.

Further, in addition to the wheel 6 and the trigger 2, the transmitter 1 is provided with a large number of operating members such as buttons. Special operations related to the operation of the steered object can be assigned to these operating members.

The head section 5 is provided with a display section 10 and a steering antenna 11. The display section 10 is inclined at a predetermined angle so that the operator can easily see the display screen when the operator grips the grip section 3. The display unit 10 is a display that displays the settings of the transmitter 1. By operating a setting operation member such as an operation button or a slide switch provided around the display unit 10, the display contents can be changed or the settings of the transmitter 1 can be changed. settings have been changed.

The steering antenna 11 is located at one end of the head section 5 located on the opposite side of the display section 10 when the operator is holding the grip section 3 (i.e., at one end of the head section 5 when the operator is holding the grip section 3). It is rotatably supported on the end (the end facing the operator and the end opposite to the operator). When remotely controlling a controlled object, the control antenna 11 is rotated 90 degrees from the horizontal state (the state shown in FIG. 2) where it forms an outer shape integrally with the head portion 5, and is used in an upright state facing vertically. Ru. By using the steering antenna 11 in an upright state, the directivity during remote control of a controlled object can be improved.

Furthermore, in addition to the display section 10 described above, the head section 5 includes an electronic circuit section including a transmitting section (communication module), a storage section, and a control section (not shown).

Note that a replaceable battery 12 is provided on the base section 4 for supplying necessary driving power to each section of the electronic circuit section (display section 10, communication module, storage section, control section).

The communication module modulates and amplifies the transmission data generated by the control unit, and transmits the modulated and amplified control signal to the controlled object via the control antenna 11 under the control of the control unit.

The storage section stores various setting information based on the operation of the setting operation member under the control of the control section. Further, the storage unit stores a control program for controlling the drive of each unit that constitutes the transmitter 1.

The control unit centrally controls the display unit 10, the communication module, and the storage unit, and generates transmission data according to the operations and settings of the wheel 6 and trigger 2, controls the display of the display unit 10, and transmits data from the communication module to the steering antenna. 11, saves setting information in the storage section, and controls the drive of each part of the transmitter 1 based on the control program stored in the storage section.

As shown in FIG. 2, the base portion 4 is formed with a larger diameter than the grip portion 3 and is provided at the other end (lower side) of the grip portion 3. This base portion 4 accommodates a battery 12. The base portion 4 has a rear portion 13 on the wrist side that supports the grip portion 3, and a front portion 14 on the finger side.

FIG. 3 is an enlarged side view of the main part of the front part 14 of the base part 4 shown in FIG. 2. As shown in FIG.
A module is detachably provided on the front part 14 of the base part 4. In this embodiment, a wireless communication module 15 that transmits and receives communication signals different from control signals is detachably provided. The wireless communication module 15 attached to the front part 14 is covered by a cover 16 that is L-shaped in side view and is attached to the base part 4 over the upper surface and tip surface of the front part 14 .

FIG. 4 is an enlarged perspective view of main parts showing the front part 14 of the base part 4 with the cover 16 and the wireless communication module 15 removed.
At the front part 14 of the base part 4, a step-shaped module mounting part 18 is formed by terminating the exterior panel 17 of the base part 4 on the way to the distal end surface. A board 19 on the main body side is exposed in the module mounting portion 18 . The main board 19 on the main body side is connected to the main board (not shown) of the operating section by a cable that passes through the grip section 3 and reaches the head section 5, or a flexible board such as FPC (Flexible Printed Circuits). One of the male and female connectors 20 is attached to the upper surface of the board 19 on the main body side.

The wireless communication module 15 includes a substrate section 21, a circuit section formed on the surface of the substrate section 21, and the other of the male and female connectors 22 (see FIG. 3) attached to the back surface of the substrate section 21. has. The substrate portion 21 is formed in a rectangular shape having a predetermined area in order to prevent radio wave interference with other portions. A circuit section is provided approximately at the center of the substrate section 21 . The circuit section includes a rectangular base plate (not shown) and a case 23 that covers electronic components such as ICs mounted on the base plate. A pattern antenna 24 is connected to the circuit section.

Note that the transmitter 1 may have a cassette-like structure that can be inserted and removed as a mounting structure for the wireless communication module 15. In this embodiment, the board 19 on the main body side and the wireless communication module 15 are connected by connectors with their board surfaces facing each other, but a structure in which their edges are butted together may also be used. For example, a slit having a terminal may be provided in the base portion 4, and the wireless communication module 15 having an edge connector may be inserted into and removed from the slit.

The wireless communication module 15 can be based on, for example, the Bluetooth standard, the Wi-Fi standard, or other wireless communication standards. The Bluetooth standard has an effective range of several tens of meters. The Wi-Fi standard has an effective range of several hundred meters, and has frequency bands of 2.4 GHz and 5 GHz. Other wireless communication standards include the 920 MHz frequency band. The 920 MHz frequency band can be used as a backup radio wave when communication is unstable in the 2.4 GHz band.

A wireless communication module 15 such as Bluetooth standard, Wi-Fi standard, etc. is detachably attached to the transmitter 1. These can extend the reach and reach of radio waves more than NFC (Near Field Communication), which is a near field communication standard. By including the wireless communication module 15, the transmitter 1 can transmit data to an external terminal via the wireless communication module 15 to transmit data to a third party when the pilot is standing at a high position such as a cockpit. Wireless communication such as viewing is now possible. Note that although NFC is used for communication by holding the device over the device, it may also be used for the purpose of sharing various data with third parties.

Approximately half of the wireless communication module 15 is a reflection plate 25. The reflector 25 is located below the pattern antenna 24. The reflecting plate 25 serves as a radio wave reflecting surface and improves the directivity of the pattern antenna 24. The wireless communication module 15 is disposed on the reflector 25 in the front part 14 of the base part 4 to provide directivity in the direction of the front (tip side) of the base part 4 and transmit and receive radio waves. It is possible. The radio waves output from the wireless communication module 15 have forward directionality in a semicircular/hemispherical shape due to the reflection plate 25 . Since the operator often uses the grip part 3 by tilting it slightly forward, by arranging the wireless communication module 15 on the front part 14 of the base part 4, the radio waves will fly forward.

A module mounting portion 18 provided on the front portion 14 is covered with a cover 16 in a state where the wireless communication module 15 is attached. In this embodiment, the cover 16 is formed in an L-shape when viewed from the side and covers the upper surface and front end surface of the front portion 14 of the base portion 4 . Note that the shape of the cover 16 is not limited to this. The cover 16 is releasably locked to the base portion 4 by a locking structure. The locking structure can be constituted by a pair of elastic locking claws 26 provided vertically on the cover 16, and locking holes 27 provided on the left and right sides of the module mounting portion 18, into which the elastic locking claws 26 lock. The locking structure further includes a claw portion 28 protruding from the front end surface of the base portion 4, and a locking recess 29 formed on the back surface of the front plate of the cover 16 and into which the claw portion 28 locks (see FIG. 3). It may have.

In this way, the cover 16 is fixed to the base portion 4 without screwing. The cover 16 is made of resin without using metal or plating to prevent radio wave interference. It should be noted that the cover 16 may be configured so that metal is disposed on the rear side so that radio waves are not directed toward the rear part 13 of the base portion 4. This makes it possible to more reliably output radio waves to the front.

The cover 16 has a connector 20 for attaching the wireless communication module 15 and a raised molded portion 30 that bulges outward opposite the module attachment portion 18 . That is, the cover 16 has a bulge in the middle of its upper surface. This bulge is for avoiding interference between the cover 16 and the case 23 when the wireless communication module 15 having a large case 23 is attached.

Next, the operation of the above configuration will be explained.

In the transmitter 1 according to the present embodiment, a head section 5 serving as an operating section is provided at one end of the grip section 3, and a base section 4 is provided at the other end of the grip section 3. The grip portion 3 of the transmitter 1 is held with the head portion 5 facing upward and the base portion 4 facing downward. The head section 5 is provided with a communication module that outputs a control signal and a control antenna 11. A wireless communication module 15 that transmits and receives communication signals different from control signals is attached to the base portion 4 .

The grip part 3 becomes heavy at the bottom because the battery 12 is housed in the base part 4. By making the upper half (i.e., the side of the head part 5) lighter and the lower half (i.e., the side of the base part 4) heavier when held, the grip part 3 is easier to position when held than the other way around. , improves balance.

In the transmitter 1, a wireless communication module 15, which is replaceably attached, is arranged on the base portion 4. As a result, in the transmitter 1, the heavy objects are collected in the lower half, and the balance during positioning is not deteriorated and becomes better. That is, by arranging the wireless communication module 15 on the lower base portion 4, the transmitter 1 can have a positive effect on the overall operational feeling.

Furthermore, in the transmitter 1, the base section 4 accommodates the battery 12, which is relatively large and heavy among the mounted components, so that it is easier to secure empty space compared to the lightweight head section 5. In the transmitter 1, the connector 20 for connecting the wireless communication module 15 and the module mounting portion 18 can be easily secured by effectively utilizing this empty space.

The module mounting portion 18 can be secured without particularly forming an accommodation space. By providing the step-shaped module mounting portion 18 on the front portion 14 of the base portion 4, it becomes possible to mount the wireless communication module 15 on the module mounting portion 18. This module mounting portion 18 is provided with one connector 20 . The wireless communication module 15 can be coupled to one of the connectors 20 and mounted on the module mounting portion 18. Thereby, the wireless communication module 15 can be attached and detached extremely easily. The wireless communication module 15 mounted on the module mounting section 18 is covered by a cover 16 that is attached to and detached from the front section 14 of the base section 4 .

Further, in the transmitter 1, a head section 5 that outputs a control signal, and a wireless communication module 15 that transmits and receives a communication signal different from the control signal, are connected to one end (upper side) and the other end (lower side) of the grip section 3. Separate with. This suppresses competition for radio waves between both antennas.

Further, in the transmitter 1, by arranging the wireless communication module 15 at the front part 14 of the base part 4, transmission and reception can be performed better than when the wireless communication module 15 is arranged at the rear part 13, which is closer to the operator's body. Note that the orientation of the transmitter 1 during use is not necessarily limited to the front section 14 being at the front and the rear section 13 being at the rear. The transmitter 1 may be held horizontally, for example, with the front-rear direction parallel to the body. Even in such a case, by providing the wireless communication module 15 on the front portion 14 of the base portion 4, the wireless communication module 15 is less susceptible to influence from the body and can perform good transmission and reception.

The wireless communication module 15 enables communication of communication signals other than control signals. Since the wireless communication module 15 can be freely coupled and uncoupled by the connector 20, it can be replaced with one of various standards. As a result, the wireless communication module 15 performs communication of communication signals other than control signals, such as image transfer, transmission and reception of backup signals for control, and transmission and reception in a stable radio wave band, without using radio waves from the operation unit. becomes possible. In this way, the transmitter 1 is configured so that weight balance, radio wave directivity, and communication environment are satisfied at the same time.

Further, in this transmitter 1, a raised molded portion 30 is formed on the cover 16. This raised molded portion 30 becomes effective when various wireless communication modules 15 are replaced or when the mounting height from the module mounting portion 18 changes. That is, in the wireless communication module 15, the circuit section is arranged at the center of the upper surface of the rectangular substrate section 21. The circuit section is connected to a wavy line pattern antenna 24. The circuit section is covered by a case 23. The specifications generally require that a space be secured around the pattern antenna 24. By having the raised molded portion 30, the cover 16 can avoid interference with cases 23 mounted at different heights in various wireless communication modules 15. As a result, wireless communication modules 15 of different heights can be provided in a detachable manner.

In addition, when the shape, size, height, etc. of the wireless communication module 15 to be attached differs, the cover 16 has a shape, size, height, or protuberance that can correspond to the shape, size, height, etc. This may be achieved by preparing a cover 16 having a forming part 30, and furthermore, a cover 16 having a raised forming part 30 having a different shape, height, etc. corresponding to the shape and height of the case 23 may be prepared. Even if the shapes, sizes, heights, etc. of the wireless communication module 15 and the case 23 are different, there is no interference between them, and various shapes can be used to match the wireless communication module 15 and the case 23. Covers 16 having various sizes and shapes of protrusion forming portions 30 may be appropriately prepared and replaced and attached.

Furthermore, even when the wireless communication module 15 is not connected to the connector 20, the cover 16 may be attached to cover the wireless communication module 15 to form the front part 14 of the base part 4. Even if there is, the wireless communication module 15 and other modules may be attached and used. For example, it is also possible to connect a module having a shape that also serves as a cover to the connector 20 and place it on the front part 14 of the base part 4 for use.

Therefore, according to the transmitter 1 according to the present embodiment, various modules such as the wireless communication module 15 for communicating communication signals different from control signals can be detachably provided.
