Description

Technical Field

[0001] This invention relates to the field of aviation teaching simulation demonstration technology, specifically to a control joystick for a simulator that can be linked to an aircraft cockpit and its usage method. Background Technology

[0002] An aircraft cockpit simulator joystick is a control device used to operate an aircraft. It is one of the main manual operating devices used by pilots to control the aircraft's flight, attitude, and flight status. With the rapid development of the domestic aviation industry, the number of aircraft and the demand for pilot training are increasing daily. However, flight training costs are high. Therefore, the rational use of simulator joysticks for basic pilot training can not only reduce training costs but also improve training safety and reduce environmental pollution. Currently, most simulator joysticks on the civilian flight simulator market are mechanical or fly-by-wire, using a central stick to simulate control of aircraft movements such as pitch and roll. However, they suffer from insufficient or excessive force feedback accuracy and sensitivity. Furthermore, there are delays in real-time data transmission, which reduces the realism of the pilot's training experience and the effectiveness of the simulation training. Moreover, the maintenance and upgrading costs of existing simulator joysticks are high. Therefore, to reduce costs and improve the realism of pilot simulation training, developing a low-cost, interconnected, highly effective, and more compatible aircraft cockpit simulator joystick is of great significance.

[0003] Given the current lack of a joystick for a simulator-compatible aircraft cockpit control system that provides a realistic simulation experience, as well as the absence of automatic force measuring devices and multiple mode selection options for aircraft cockpit joysticks, this invention discloses a joystick for a simulator-compatible aircraft cockpit control system, aiming to achieve teaching and training objectives in a more intuitive, safer, more innovative, and lower-cost manner. Summary of the Invention

[0004] The purpose of this invention is to provide a control joystick for a simulator that can be linked to an aircraft cockpit and a method of using it, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A control stick for a simulator that can be linked to an aircraft cockpit includes a linkage switching device, a pitch linkage centering device, and a roll linkage centering device. The linkage switching device is respectively disposed at both ends of the top of the pitch linkage centering device, and the roll linkage centering device is disposed at the bottom of the pitch linkage centering device. The linkage conversion device includes a steering wheel, a head housing, and a roll conversion spindle. The bottom of the roll conversion spindle is installed at the top end of the pitch linkage centering device. The head housing is installed on the top of the roll conversion spindle, and the steering wheel is installed on the side of the head housing. The pitch linkage centering device includes a pitch linkage tube, with a pitch linkage tube extension block fixed at each end of the tube. A pitch gas spring fixing frame is mounted on each of the two pitch linkage tube extension blocks. An extension block shaft is provided on the end face of the two pitch linkage tube extension blocks. A pitch support bearing is mounted on the extension block shaft. A roll stop fixing frame is fixed on the tube surface on one side of each end of the pitch linkage tube by two roll stop fixing frame fixing bolts. A limit bolt is screwed to the lower end of each of the two roll stop fixing frames. A roll centering core block I and a roll centering core block II are provided on the lower tube surface at both ends of the pitch linkage tube. The rolling linkage centering device includes a rolling linkage square tube I and a rolling linkage square tube II, which are arranged at intervals. Rolling extension blocks are installed on both ends of the rolling linkage square tube I and the rolling linkage square tube II by rolling linkage square tube fixing nuts and rolling linkage square tube fixing bolts.

[0006] Preferably, a roll head spindle is installed through the inner cavity of the head housing. A roll head spindle stop is fitted on the right side of the outer ring of the head housing. A steering wheel retainer is fitted on the right side of the outer ring of the head housing. A tensioning sleeve is fitted on the outer ring of the protruding end of the steering wheel retainer. The steering wheel is mounted on the side of the steering wheel retainer by fasteners. A roll head spindle locking nut is installed on the left side of the outer ring of the roll head spindle. A roll head spindle tail support bearing, a steering bevel gear II, and a support bearing II are sequentially fitted on the left side of the outer ring of the roll head spindle. The support bearing II is fitted on the roll head spindle cam.

[0007] Preferably, a steering bevel gear I and a support bearing I are mounted on the top of the roll conversion spindle via an upper thin shaft, and the steering bevel gears I mesh with each other. A pitch support tube is fitted on the outer ring of the roll conversion spindle.

[0008] Preferably, the roll centering core block I and the roll centering core block II are connected to both ends of the pitch linkage tube by roll centering core block fixing bolts and roll centering core block fixing nuts, respectively. Two roll centering spring fixing bolts are screwed onto the roll centering core block I and the roll centering core block II, and a roll centering spring is connected to each of the two symmetrically fixed roll centering spring fixing bolts. Two limiting bolts are respectively set between the roll centering core block I and the roll centering core block II at both ends of the pitch linkage tube on the corresponding side. The two roll centering core blocks I and the roll centering core block II can rotate left and right below the two ends of the pitch linkage tube.

[0009] Preferably, bolt holes are provided on the square tube surfaces at both ends of the horizontal rolling linkage square tube II, and a horizontal rolling centering block fixing bolt is threaded into the bolt holes. A horizontal rolling centering block is fitted on the outer ring of the horizontal rolling centering block fixing bolt, and a horizontal rolling centering block fixing nut is installed at the end of the horizontal rolling centering block fixing bolt. The horizontal rolling centering block and the horizontal rolling centering block fixing bolt are in clearance fit.

[0010] Preferably, a pitch support tube fixing plate is installed below the pipe openings at both ends of the pitch linkage tube, and a fixing sleeve fixing bolt is provided in each of the multiple holes of the pitch support tube fixing plate.

[0011] Preferably, the roll conversion spindle is provided with an upper protruding shaft I and a lower protruding shaft II on the outer wall of the inner cavity of the pitch support tube. A roll spindle support bearing is installed at the bottom of the roll conversion spindle, and a pitch support tube fixing sleeve is fitted on the outer ring of the roll spindle support bearing.

[0012] A method for using a control stick for a simulator in an aircraft cockpit includes the following steps: S1: Controlled by the control wheel, the movements of the control wheel are transmitted to the aircraft simulator system through the roll conversion spindle and pitch linkage, realizing the control of the aircraft's pitch and roll.

[0013] S2: During operation, the pitch-linked centering device and the roll-linked centering device will provide an automatic return-to-center function to ensure the stability of the flight attitude; S3: During flight, the operation is transmitted to the pitch linkage centering device through the control stick, head shell and roll conversion main shaft in the linkage conversion device. The pitch linkage tube, support bearing and roll stop block fixing frame realize precise control of pitch and roll. The roll linkage square tube I and roll centering block of the roll linkage centering device provide centering function, thereby realizing fine angle adjustment and automatic return to center. The control stick will simulate the aerodynamic force and inertial feedback in real flight. S4: During descent, gradually reduce the movement of the control stick and use the automatic return-to-center function to make the aircraft land smoothly.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: This interlocking aircraft cockpit control stick for simulators features an interlocking structure for the primary and co-pilot sticks. This allows for synchronized operation between the two sticks, ensuring perfect consistency in control actions. This design overcomes the asynchrony issues associated with non-interlocking sticks found in lower-level simulators. During flight simulation training, the two pilots can cooperate to simulate a more realistic flight environment, improving operational reliability and training effectiveness. Furthermore, this interlocking structure reduces the risk of misoperation due to stick asynchrony, further enhancing the safety and reliability of simulation training.

[0015] The simulator's linked aircraft cockpit control stick employs pitch-linked and roll-linked centering mechanisms, allowing the stick to automatically return to center after the pilot adjusts the aircraft's attitude, eliminating the need for manual adjustment. This design aligns better with ergonomic principles, reducing the pilot's workload during extended training sessions and minimizing fatigue from continuous operation. Furthermore, this automatic centering function enhances the simulator's realism, making its operation more closely resemble that of a real aircraft. In actual flight, the stick automatically returns to a neutral position after being released, a mechanism that more realistically simulates this characteristic, providing pilots with a more immersive training environment and helping them better adapt to the operational requirements of real flight. Through this design, pilots can experience a more natural and intuitive control experience during training.

[0016] This simulator-compatible cockpit control stick uses a hydraulic system to simulate the aerodynamic and inertial feedback of real flight, providing more accurate force feedback and enhancing the pilot's realistic operating experience. The hydraulic system precisely simulates various forces experienced by the aircraft during flight, including aerodynamic forces, gravity, and inertial forces generated by changes in flight attitude. These forces are transmitted to the control stick via the hydraulic system, allowing the pilot to feel drag and reaction forces similar to those experienced in actual flight. This realism not only improves the pilot's precision in controlling the control stick but also allows them to experience force changes under different flight conditions during training, such as acceleration, deceleration, turning, and turbulence, thereby better mastering flight skills.

[0017] This interactive aircraft cockpit control stick for simulators is designed to scale up the entire control stick system. Its compact design saves on design, manufacturing, and maintenance costs, as well as cockpit space. However, its functions are the same as those of a normal-sized system, mainly including force feedback and ergonomics, which are identical to those of an actual control stick.

[0018] This interoperable aircraft cockpit control joystick for simulators features a universal installation interface design, allowing it to be integrated with various simulator training platforms. Compared to dedicated training joysticks, it is more cost-effective and achieves wide applicability.

[0022] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention provides a technical solution for a flight simulator with a linkage aircraft cockpit control joystick: like Figure 1 As shown, the joystick mainly includes a linkage conversion device 1, a pitch linkage centering device 2, and a roll linkage centering device 3. The linkage conversion device 1 is respectively located at both ends of the top of the pitch linkage centering device 2, and the roll linkage centering device 3 is located at the bottom of the pitch linkage centering device 2.

[0025] Among them, as shown in the figure and Figure 6 As shown, the linkage conversion device 1 includes a steering wheel 1-1, a head housing 1-2, and a roll conversion spindle 1-6. The bottom of the roll conversion spindle 1-6 is installed at the top end of the pitch linkage centering device 2. The head housing 1-2 is installed on the top of the roll conversion spindle 1-6, and the steering wheel 1-1 is installed on the side of the head housing 1-2. Among them, such as Figure 3 , Figure 4 Figure 5 and Figure 7 As shown, the pitch linkage centering device 2 includes a pitch linkage tube 2-1, a pitch linkage tube extension block 2-4 fixed at each end of the pitch linkage tube 2-1, a pitch gas spring fixing bracket 2-5 clamped on each of the two pitch linkage tube extension blocks 2-4, an extension block shaft 2-4-1 set on the end face of the two pitch linkage tube extension blocks 2-4-1, a pitch support bearing 2-6 fitted on the extension block shaft 2-4-1, a roll stop fixing bracket 2-2 fixed on one side of the pitch linkage tube 2-1 by two roll stop fixing bracket fixing bolts 2-15, a limit bolt 2-3 screwed to the lower end of each of the two roll stop fixing brackets 2-2, and a roll centering core block I 2-10 and a roll centering core block II 2-11 set on the lower tube surface at both ends of the pitch linkage tube 2-1; This application integrates multiple high-precision force sensors into the control stick, enabling real-time monitoring of the forces applied by the pilot. A hydraulic system transmits the detected forces back to the control stick, ensuring the pilot experiences the same force feedback as in actual flight. A high-performance data processing unit further enhances the system by processing sensor data in real time and dynamically adjusting the force feedback based on flight conditions, guaranteeing accuracy and consistency.

[0026] This application also includes a library of preset modes, including normal flight mode, emergency mode, and flight modes for different weather conditions. Each mode corresponds to different force feedback and control characteristics. An intuitive user interface is provided, allowing pilots to easily select and switch control modes. In different modes, the system adjusts the feedback parameters of the hydraulic system and force sensors according to the selected mode to simulate different flight states and control requirements.

[0027] Among them, such as Figure 3 , Figure 4 Figure 5 and Figure 7 As shown, the horizontal rolling linkage centering device 3 includes a horizontal rolling linkage square tube I 3-1 and a horizontal rolling linkage square tube II 3-2.

[0028] In this embodiment, the aircraft control stick is designed as a linked structure, meaning that the pilot and co-pilot operate the same controls, thus overcoming the problem of asynchronous control sticks in previous low-level simulators and improving operational reliability. A linked centering device is used, meaning that after adjusting the aircraft attitude, the control stick automatically returns to center after the pilot releases it, without requiring manual operation. This better conforms to ergonomics, resulting in higher simulation fidelity and similarity to real aircraft operation. The entire control stick system is simulated proportionally through optimized design, resulting in a compact design that saves on design, manufacturing, and maintenance costs, as well as cockpit space. However, the functionality is identical to a system of normal size, primarily including force feedback and ergonomics aspects, which are indistinguishable from actual control sticks.
