Description
Technical Field
[0001] The invention relates to the technical field of flight simulator control rods, in particular to a flight simulator control rod based on a planetary reduction motor. Background Art
[0002] There are two main types of force feedback for flight simulator sticks at present. The first is the unmanned spring return method, and the second is the AC servo motor drive method. The first spring return method can only provide a relatively fixed force and cannot provide a normal force feeling for simulated flight. The second AC servo motor drive method, because the motor size is large and requires a matching servo controller, makes the entire system huge and expensive.
[0003] In the traditional spring return method, the force feedback device is a spring, which cannot control the feedback force in real time, so it cannot provide normal force feeling for simulated flight.
[0004] The traditional AC servo motor drive method, due to the separation of the motor, reducer and servo controller, leads to a large overall system size and high cost.
[0005] Furthermore, if the operator performing the simulated flight has large hands, it is inconvenient to hold the slender operating handle, or if a novice is prone to nervousness and sweating during operation, the relatively smooth operating handle is not conducive for a novice to hold. Summary of the invention
[0006] The purpose of the present invention is to solve the problem of the device and to propose a flight simulator joystick based on a planetary reduction motor.
[0007] To achieve the above object, the present invention provides the following technical solutions: A flight simulator joystick based on a planetary reduction motor is designed, comprising a mounting panel and a support frame, wherein the lower end of the mounting panel is fixedly connected to the support frame, an X-axis support is fixedly connected to the upper left portion of the inner wall of the support frame, an X-axis planetary reduction motor is mounted on the rear side of the X-axis support, and a mounting hole of the X-axis planetary reduction motor is connected to an operating handle through a positioning connector.
[0008] Preferably, an auxiliary grip is installed on the outer wall of the operating handle, and the auxiliary grip includes a half-side grip and a rubber bump, and the two half-side grips are respectively distributed on the front and rear sides of the outer wall of the operating handle.
[0009] Preferably, a power module is fixedly connected to the center of one side of the inner wall of the support frame, and a control chip is fixedly connected to the lower end of the inner wall of the support frame.
[0010] Preferably, communication interface 1 and communication interface 2 are installed on one side of the rear end of the outer wall of the support frame.
[0011] Preferably, a decorative cover is installed below the outer wall of the operating handle.
[0012] Preferably, the rotating part of the X-axis planetary reduction motor is installed with an X-axis limiter, and a Y-axis planetary reduction motor is installed inside the upper right side of the support frame. The mounting hole of the Y-axis planetary reduction motor is connected to the X-axis support through a positioning connector, and the rotating part of the Y-axis planetary reduction motor is installed with a Y-axis limiter.
[0013] Preferably, the inner wall of the half-handle is processed with a plurality of notches, the plurality of rubber protrusions are equidistantly distributed and fixed on the outer wall of the operating handle, and the fitting surface of the half-handle is processed with a chamfer.
[0014] Preferably, the inner walls of the half handles are fixedly connected with a plurality of magnetic blocks, and the inner walls of the half handles on both sides are fixed by adsorption of the magnetic blocks.
[0015] The present invention proposes a flight simulator joystick based on a planetary reduction motor, which has the following beneficial effects: Through the cooperation among the operating handle, X-axis limit, Y-axis limit, X-axis planetary reduction motor and Y-axis planetary reduction motor, the operating handle is directly connected and fastened to the mounting hole of the planetary reduction motor through the positioning machined part, and the rotating part of the planetary reduction motor collides with the limit block (X-axis limit and Y-axis limit) installed on the outer ring of the motor to realize the limiting function of the extreme swing angle. Since the X-axis planetary reduction motor and the Y-axis planetary reduction motor and the mounting components are independent of each other, when the operating handle performs a swing of a certain action alone, it will not affect the position change of another swing direction.
[0016] Through the coordination among the half grips, the operating handle, the notch, the rubber bumps and the magnets, the half grips on both sides are buckled onto the outer wall of the operating handle respectively. During the process, it is necessary to ensure that the notch and the rubber bumps on the outer wall of the operating handle are relatively aligned. After the final buckling, the half grips on both sides are buckled onto the outer wall of the operating handle by adsorption by multiple groups of magnetic blocks, thereby realizing the installation of the auxiliary grip, so that the operator can hold the auxiliary grip better and more adaptably with his hand, effectively avoiding the problem that the operator having large hands performing simulated flight finds it inconvenient to hold the slender operating handle, or the problem that the novice is prone to nervousness and sweating during operation, and the smoother operating handle is not conducive to the novice's grip.

[0019] The present invention will be further described below in conjunction with the accompanying drawings: See attached Figure 1-5 : In the present embodiment, a flight simulator joystick based on a planetary reduction motor comprises a mounting panel 3 and a support frame 4, wherein the lower end of the mounting panel 3 is fixedly connected to the support frame 4, an X-axis support 7 is fixedly connected to the upper left portion of the inner wall of the support frame 4, an X-axis planetary reduction motor 10 is mounted on the rear side of the X-axis support 7, the mounting hole of the X-axis planetary reduction motor 10 is connected to an operating handle 1 through a positioning connector, an X-axis limit 6 is mounted on the rotating portion of the X-axis planetary reduction motor 10, a Y-axis planetary reduction motor 14 is mounted inside the upper right portion of the support frame 4, the models of the X-axis planetary reduction motor 10 and the Y-axis planetary reduction motor 14 can be determined according to specific usage conditions, the mounting hole of the Y-axis planetary reduction motor 14 is connected to the X-axis support 7 through a positioning connector, and the rotating portion of the Y-axis planetary reduction motor 14 is mounted with a Y-axis limit 8, and the X-axis limit 6 and the Y-axis limit 8 can limit the extreme positions of the operating handle 1 on the X-axis and Y-axis.
[0020] The X-axis planetary reduction motor 10 and the Y-axis planetary reduction motor 14 use high-power brushless motors with built-in planetary reducers and drivers, which have the advantages of large power torque, small size and high precision. The mechanical structure is used to directly drive the X-axis and Y-axis of the joystick to rotate without introducing other transmission mechanisms, further reducing the system size. The control chip 5 uses a high-frequency STM32F4 microcontroller as the core, which collects the position of the joystick in real time and quickly completes the force feedback algorithm to accurately control the motor torque. At the same time, it communicates with the simulation system in real time. The flight simulator software uses the host computer software written in VB to only monitor the human sense state and current parameters in real time, and can control the human sense and adjust the parameters in real time.
[0021] See attached Figure 1-5In the present embodiment, an auxiliary grip 15 is installed on the outer wall of the operating handle 1. The auxiliary grip 15 includes a half grip 16 and rubber protrusions 19. The rubber protrusions 19 can increase the friction of the outer wall of the operating handle 1. The two half grips 16 are respectively distributed on the front and back sides of the outer wall of the operating handle 1. The inner wall of the half grip 16 is processed with a plurality of notches 18. The plurality of rubber protrusions 19 are equidistantly distributed and fixed on the outer wall of the operating handle 1. The fitting surface of the half grip 16 is processed with a chamfer 17. When it is necessary to disassemble the half grips 16 on both sides, the user can insert a flat-head screwdriver into the chamfers 17 of the fitting surfaces of the half grips 16 on both sides, pry open and remove the half grips 16 on both sides, and the inner walls of the half grips 16 are fixed with a plurality of magnetic blocks 20. The inner walls of the half grips 16 on both sides are adsorbed and fixed by the magnetic blocks 20.
[0022] See attached Figure 1-5 : In this embodiment, a power module 11 is fixedly connected to the center of one side of the inner wall of the support frame 4. When in use, the power module 11 is connected to the electronic components in this case to provide power, and the power module 11 has its own charging hole for charging. A control chip 5 is fixedly connected to the lower end of the inner wall of the support frame 4. The control chip 5 is connected to the electronic components in this case and can process the signals at the X-axis planetary reduction motor 10 and the Y-axis planetary reduction motor 14. A communication interface 12 and a communication interface 2 13 are installed on one side of the rear end of the outer wall of the support frame 4. The communication interface 12 and the communication interface 2 13 are used to connect to external software equipment (flight simulator) and a display screen. A decorative cover 2 is installed at the lower part of the outer wall of the operating handle 1.
[0023] Working principle: When the flight simulator joystick based on the planetary reduction motor is needed to be used, first, the signal lines corresponding to the external software device (flight simulator) and the display screen are inserted into the communication interface 12 and the communication interface 2 13, and then the overall structure can be installed on the corresponding base through the threaded holes on the outer edge of the mounting panel 3. During specific use, the operator can hold the operating handle 1 to rotate it in the X-axis direction and the Y-axis direction, and the corresponding rotation can be transmitted to the X-axis planetary reduction motor 10 and the Y-axis planetary reduction motor 14 respectively. The X-axis planetary reduction motor 10 and the Y-axis planetary reduction motor 14 process the pushing degree of the handheld operating handle 1 through the control chip 5, and transmit the data and The signal is transmitted through communication interface 12 and communication interface 2 13, and is sent to the external software device (flight simulator) and the display screen, so that the aircraft in the display screen performs corresponding flight simulation. The operating handle 1 in this case is directly connected and fastened to the mounting hole of the planetary reduction motor through a positioning machined part. The rotating part of the planetary reduction motor collides with the limit blocks (X-axis limit 6 and Y-axis limit 8) installed on the outer ring of the motor to achieve the function of limiting the extreme swing angle. Since the X-axis planetary reduction motor 10 and the Y-axis planetary reduction motor 14 and the mounting components are independent of each other, when the operating handle performs a swing of a certain action alone, it will not affect the position change of another swing direction.
[0024] At the same time, if the operator performing simulated flight has large hands and it is inconvenient to hold the slender operating handle 1, or if a novice is prone to nervousness and sweating during operation, and the relatively smooth operating handle 1 is not conducive to the novice's grip, at this time, according to the needs of the operator, the half grips 16 on both sides can be buckled on the outer wall of the operating handle 1 respectively. During the process, it is necessary to ensure that the notch 18 and the rubber protrusions 19 on the outer wall of the operating handle 1 are aligned, and after the final buckling, the half grips 16 on both sides are adsorbed by multiple groups of magnetic blocks 20 to achieve the buckling of the outer wall of the operating handle 1, so as to achieve the installation of the auxiliary grip 15, so that the operator can hold the auxiliary grip 15 better and more adaptably with his hand, thereby driving the operating handle 1 to move. When it is necessary to remove the half grips 16 on both sides, the user can insert a flat-head screwdriver into the chamfers 17 of the fitting surfaces of the half grips 16 on both sides, and pry open and remove the half grips 16 on both sides.
[0025] Although the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
