Description

Technical Field

[0001] This invention belongs to the field of aircraft pedal simulation technology and is used for aircraft simulation flight training to improve the realism and stability of simulation training. In particular, it relates to a torque transmission device for aircraft simulation pedals and servo motors. Background Technology

[0002] Aircraft control systems typically include manual control and automatic control systems. Manual control systems can be further divided into primary control systems and secondary control systems. The primary control system includes a control stick and pedals. The control stick controls the elevator, and the pedals control the rudder, thereby controlling the aircraft's flight path and attitude. Force feedback control devices are the direct devices used by pilots to control the aircraft. Due to the complex flight environment and variable flight attitude, the data fed back to the pedals changes rapidly. Pilots must quickly make corresponding judgments and execute operations based on force feedback data. This requires pilots to accumulate experience through long-term training on real aircraft. Considering the safety and economic benefits of real aircraft training, professional aircraft simulation control devices are needed to simulate the control force feedback of real aircraft. An existing aircraft pedal linkage mechanism, patent number (CN112793764B), effectively reduces the probability of pilot error, facilitates training and learning, reduces the complexity of the aircraft control system, helps reduce the failure rate, and has high operational precision. However, in actual training, because the two ends of the spring are fixedly connected to the housing and cannot be adjusted, it is impossible to provide force feedback for different flight attitudes, resulting in problems with the realism and stability of the simulation training. Therefore, to address the problems mentioned in the background art, this invention provides a torque transmission device for aircraft simulation pedals and servo motors to solve the problems existing in the prior art.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] like Figure 1 As shown, a torque transmission device for an aircraft simulation pedal and servo motor includes a fixed bracket 5, a transmission mechanism and a force feedback mechanism disposed within the fixed bracket 5. The force feedback mechanism is rotatably connected to the transmission mechanism and provides feedback force to the transmission mechanism. The transmission mechanism includes a rotating shaft 9, one end of which extends out of the upper end of the fixed bracket 5 and is provided with a mounting seat. Two connecting rods 3 are symmetrically arranged on the mounting seat, and foot pedals 2 are respectively disposed on the other ends of the two connecting rods 3. During operation, a forward or backward force is applied to the foot pedal 2 and transmitted to a gear potentiometer 7 through the transmission mechanism. The gear potentiometer 7 collects the signal and feeds it back to the server. The server and software realize the forward and backward heading attitude of the aircraft simulation pedal, and provide force feedback through the action of the servo motor 1, so that the pilot has a realistic feeling of operating a real aircraft, thereby improving the realism and stability of aircraft simulation training.

[0023] like Figure 2 ---- Figure 5As shown, in this embodiment, it requires the use of an aircraft simulation joystick electric load control system and server. The aircraft simulation joystick electric load control system and server are used to process the data collected by the gear potentiometer 7 and display it in simulation. They also process and transmit the collected data to the servo motor 1 to control the torque output of the servo motor 1. The torque output by the servo motor 1 is transmitted to the mounting base, linkage 3, and foot pedal 2 through the transmission component 8, providing corresponding feedback force to give the pilot a realistic feeling of operating a real aircraft. The fixed bracket 5 is rectangular and is equipped with a base for mounting the servo motor 1 and a mounting plate. The mounting bracket for the rotating shaft 9 is made entirely of steel. The gear potentiometer 7 is model R1001N-35. During actual installation, the mounting bracket 5 contains a transmission mechanism and a force feedback mechanism. The force feedback mechanism is rotatably connected to the transmission mechanism to receive the force from the transmission mechanism and provide feedback force. The transmission mechanism includes a rotating shaft 9, one end of which extends out of the upper end of the mounting bracket 5 and is fitted with a mounting base. The mounting base is connected to the rotating shaft 9 mechanism. Two connecting rods 3 are symmetrically arranged on the mounting base, and foot pedals 2 are respectively mounted on the other ends of the two connecting rods 3. Each foot pedal 2 has a foot pedal fixing block. The fixed block is connected to the foot pedal 2 mechanism. The connecting rod 3 includes a large connecting rod and a rear connecting rod. The two ends of the large connecting rod and the rear connecting rod are rotatably connected to the foot pedal fixed block and the mounting base respectively through a pin. The large connecting rod is used to support the foot pedal fixed block and the foot pedal 2, and the rear connecting rod is used to connect the fixed block and ensure the front and rear displacement direction of the foot pedal 2. An adjusting shaft 6 is installed on the mounting base, and an upper cover 4 is provided on the mounting base. The cross-section of the upper cover 4 is L-shaped. The horizontal surface of the upper cover 4 is connected to the mounting base mechanism. There is a gap between the lower end of the vertical surface of the upper cover 4 and the upper end surface of the fixed bracket 5. Both ends of the adjusting shaft 6 extend out of the mounting base and pass through the vertical surface of the upper cover 4. On the front, the adjusting shaft 6 is equipped with an adjusting ring and an adjusting handle, which are threadedly connected to the adjusting shaft 6 and the adjusting ring and the adjusting handle. The adjusting ring and the adjusting handle are located on both sides of the mounting base. A small connecting rod is provided on the large connecting rod. One end of the small connecting rod is connected to the adjusting ring insert shaft, and the other end is connected to the large connecting rod insert shaft. Rotating the adjusting handle causes the adjusting shaft 6 to move back and forth within the mounting base, which in turn causes the adjusting ring, the small connecting rod, the large connecting rod, and the foot pedal 2 to move back and forth, thereby adjusting the front and rear position of the foot pedal 2, suitable for use by people of different heights. A bearing is provided on the rotating shaft 9, which is connected to the fixed bracket 5 through the bearing seat and the base plate to stabilize the rotating shaft.A transmission gear and a gear potentiometer 7 are mounted on the rotating shaft 9, located below the bearing. The gear potentiometer 7 is connected to the fixed bracket 5 via a potentiometer fixing plate. The gear on the gear potentiometer 7 meshes with the transmission gear. When the foot pedal 2 moves back and forth, the generated force is transmitted to the mounting base and the rotating shaft 9 via the connecting rod 3. The rotating shaft 9 drives the transmission gear and the gear potentiometer 7 to rotate. The gear potentiometer 7 is connected to an external server, which houses an aircraft simulation control stick electric load control system. The server processes the collected data and displays the simulation results on the aircraft simulation control stick electric load control system. A servo motor 1 is mounted on the fixed bracket 5. A gear potentiometer 7 is electrically connected to the servo motor 1. The signal processed by the server is transmitted to the servo motor 1, driving it to provide corresponding force. A transmission assembly 8 is mounted on the servo motor 1. The transmission assembly 8 includes a crank and a connecting rod. One end of the crank is fixedly connected to the output shaft of the servo motor 1, and the other end is rotatably connected to the connecting rod via a pin. One end of the connecting rod is rotatably connected to the mounting base via a pin. The force output by the servo motor 1 is transmitted through the transmission assembly 8 to the mounting base, connecting rod 3, and foot pedal 2, providing corresponding feedback force to the foot pedal 2 and giving the driver a realistic feeling of operating a real machine.

[0024] In practice, before boarding the aircraft, the pilot adjusts the foot pedal 2 to a suitable forward or backward travel by rotating the adjustment handle. During operation, a forward or backward force is applied to the foot pedal 2. The force generated by the foot pedal 2 is transmitted to the mounting base and rotating shaft 9 through the linkage 3, and then to the gear potentiometer 7 through the transmission gear. The gear potentiometer 7 collects the signal and feeds it back to the server. The server and the aircraft simulation control stick electric load control system realize and display the forward and backward heading attitude of the aircraft simulation foot pedal. At the same time, the server and the aircraft simulation control stick electric load control system analyze the force feedback data and transmit it to the servo motor 1. The servo motor 1 drives the transmission component 8 to transmit the force to the mounting base through the corresponding number of rotations, and then to the foot pedal 2 through the linkage, causing the foot pedal 2 to move forward and backward. The function of the servo motor 1 is to provide a force feel, so that the pilot has a realistic feeling of operating a real aircraft, and finally simulates the heading attitude of the aircraft, thereby improving the realism and stability of the aircraft simulation training.

[0025] This invention incorporates a transmission mechanism and a force feedback mechanism within a fixed support 5. The force feedback mechanism is rotatably connected to the transmission mechanism and provides feedback force to it. During operation, a forward or backward force is applied to the foot pedal 2 and transmitted through the transmission mechanism to the gear potentiometer 7. The gear potentiometer 7 collects the signal and feeds it back to the server for processing. The server and software realize the forward and backward heading attitude of the aircraft simulation foot pedal and provide force feedback through the action of the servo motor 1, giving the pilot a realistic feeling of operating a real aircraft, thereby improving the realism and stability of aircraft simulation training.

Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
