Abstract
Description
Technical Field
[0001] This utility model relates to the field of control device technology, specifically to a flight training control device. Background Technology
[0002] The control stick is the core device for pilots to control the aircraft's flight attitude. It is linked to the aircraft's elevator and ailerons through mechanical, hydraulic, or fly-by-wire systems and is mainly responsible for controlling the nose's vertical movement and the wings' horizontal tilt.
[0003] The inventors discovered that existing joysticks integrate more function buttons, requiring trainees to avoid accidental operation when using them, and physical buttons still require more precise control. Furthermore, the optimal joystick position varies significantly depending on the trainee's arm length and posture; traditional fixed-position designs rely on trainees adapting to the device, leading to fatigue during prolonged use.
[0004] With the steady development of technology and the popularization of fly-by-wire systems, joysticks have integrated more function buttons, such as autopilot disengagement, trim control, and lighting adjustment. A utility model patent with Chinese authorized patent number CN208689777U discloses a joystick mechanism for a helicopter simulator. The joystick mechanism is installed in front of the pilot's seat of the simulator through a base connecting piece, so that the joystick and the handles at both ends are located on both sides directly in front of the pilot's seat, thereby simulating the position of the joystick in a real helicopter. Its structure is simple, the cost is low, and it meets the needs of simulation operation training. However, the joystick mechanism still has the following problems when in use: (1) The joystick has only one independent lever and does not integrate different operation buttons, so it cannot comprehensively train the operation buttons on the existing aircraft joysticks. Correspondingly, it cannot solve the problem of accidental touch of operation buttons; (2) The height of the joystick cannot be adjusted according to the arm length of different trainees. Summary of the Invention
[0005] To address the aforementioned problems, this utility model aims to provide a flight training control device. A self-locking mechanism is provided on the control stick. The self-locking mechanism includes a self-locking button, a hydraulic component, and a conductive washer. The trainee presses the self-locking button, which connects the hydraulic component to the operating button, allowing operation of the button. When not using the operating button, releasing the self-locking button disconnects the hydraulic component from the operating button, thus preventing accidental button activation.
[0006] The main idea of the technical solution adopted by this utility model is as follows: by setting a self-locking mechanism on the joystick, the contact and the operation button are connected or disconnected. When using the operation button, the trainee presses the self-locking button of the self-locking mechanism, and the hydraulic component pushes the conduction pad to realize the operation of the operation button.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A flight training control device includes a joystick, and further includes: contacts installed inside the joystick; a plurality of operation buttons that slide through the joystick and correspond one-to-one with the contacts; and a self-locking mechanism disposed on the joystick for connecting or disconnecting the contacts and operation buttons.
[0009] Furthermore, the self-locking mechanism includes: a self-locking button slidably disposed on the control lever; a hydraulic component installed inside the control lever and communicating with the self-locking button; and a plurality of conductive pads corresponding one-to-one with the plurality of operation buttons, wherein each conductive pad is provided with a through hole for the operation button to pass through, and each conductive pad is connected to the hydraulic component.
[0010] Furthermore, the hydraulic assembly includes: a hydraulic pipe installed inside the control lever and connected to the self-locking button; a piston rod slidably disposed inside the hydraulic pipe for pushing the conductive gasket to open or close the contacts and the operating button; and a reset member connected to the piston rod for resetting the piston rod.
[0011] Furthermore, the hydraulic assembly also includes: multiple connecting rods, each corresponding to one of the multiple conductive pads, with both ends respectively connected to the piston rod and the conductive pad.
[0012] Furthermore, the flight training control device also includes: a limiting frame, which is sleeved on the outer periphery of the conductive pad and has a sliding groove on the outer side; and a fixed bracket, one end of which is slidably engaged with the sliding groove and the other end of which is connected to the control stick.
[0013] Furthermore, the flight training control device also includes: a telescopic rod, sleeved on the outside of the control stick and connected to the control stick; and a soft rubber sleeve, sleeved on the outer periphery of the telescopic rod, for connecting the telescopic rod to the base of the control device.
[0014] The beneficial effects of this utility model are:
[0015] 1. By incorporating a self-locking button, hydraulic components, and conductive pads on the joystick, the hydraulic components can move the conductive pads only when the self-locking button is pressed, thus enabling the operation button and contacts to conduct. When the self-locking button is released, the through holes on the conductive pads deviate from the operation button and contacts, preventing them from conducting. This design prevents trainees from accidentally pressing buttons during joystick training, thus avoiding disruption to training effectiveness.
[0016] 2. This utility model also has a telescopic rod at the bottom of the control lever, which can adjust the height of the control lever according to the trainee's arm length, thereby improving the trainee's training comfort. Attached Figure Description

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0024] Example 1
[0025] See Figures 1-5This application discloses a flight training control device, including a joystick 1. The joystick 1 has a hollow structure, and multiple contacts 14 are fixedly arranged inside the joystick 1. Multiple operation buttons 15, each corresponding to one of the contacts 14, are also slidably arranged on the joystick 1. A self-locking mechanism is provided on the joystick 1, which is used to connect or disconnect the contacts 14 and the operation buttons 15. After the trainee presses the self-locking mechanism, when an operation button 15 is pressed, it connects with the contacts 14. After releasing the self-locking mechanism, pressing the operation button 15 again will prevent the connection between the operation button 15 and the contacts 14 from executing the command of the corresponding operation button 15, thereby avoiding accidental activation of the operation buttons 15.
[0026] Specifically, the self-locking mechanism includes a self-locking button 2, a hydraulic assembly, and a conductive pad 3. The self-locking button 2 is slidably mounted on the outer wall of the control lever 1 and is connected to the hydraulic assembly. When the user presses the self-locking button 2, it enters the hydraulic assembly, changing the internal pressure. The hydraulic assembly and the conductive pad 3 are located within the mounting cavity of the control lever 1, and the hydraulic assembly is connected to the conductive pad 3. The conductive pad 3 corresponds one-to-one with the operation button 15, and has through holes 13 for connecting the contact point 14 and the operation button 15. When the self-locking button 2 is pressed, the internal pressure of the hydraulic assembly increases, causing the conductive pad 3 to move away from the hydraulic assembly. At this time, the through holes 13 correspond to the positions of the operation button 15 and the contact point 14. When the trainee presses the operation button 15, the end of the operation button 15 near the contact 14 passes through the through hole 13 and contacts the contact 14, thus connecting the contact 14 and the operation button 15. When the self-locking button 2 is released, the internal pressure of the hydraulic component decreases, causing the conductive pad 3 to move towards the end closer to the hydraulic component. The through hole 13 on the conductive pad 3 deviates from the axis of the contact 14 and the operation button 15. The conductive pad 3 separates the contact 14 and the operation button 15, making it impossible to press the operation button 15, thus causing the operation button 15 and the contact 14 to contact.
[0027] Preferably, in this embodiment, the control lever 1 is a Cirrus SR20, and the self-locking button 2 is a spring-loaded self-locking structure with a press-to-reset function, a structure well-known to those skilled in the art, and will not be described in detail here. A cap (not shown in the figure) is also fitted over the self-locking button 2, and the cap is glued and fixed to the outer wall of the control lever 1 to protect the self-locking button 2.
[0028] The hydraulic assembly includes a hydraulic pipe 6 and a piston rod 5. The hydraulic pipe 6 is completely sealed. The self-locking button 2 slides through the hydraulic pipe 6, and the piston rod 5 slides through and seals the hydraulic pipe 6. By pressing the self-locking button 2, the button enters or exits the hydraulic pipe 6, changing its internal volume and squeezing the liquid (or gas) within it. This causes the liquid (or gas) to push the piston rod 5. A reset element 4 is provided between the piston rod 5 and the hydraulic pipe 6. One end of the reset element 4 is connected to the hydraulic pipe 6, and the other end abuts against one end of the piston rod 5. This reset element 4 automatically resets the piston rod 5 when the self-locking button 2 is released. In this embodiment, the reset element 4 is a spring.
[0029] In some other specific embodiments, the reset member 4 may also be disposed between the end of the piston rod 5 away from the hydraulic pipe 6 and the inner wall of the control lever 1.
[0030] Furthermore, the piston rod 5 is hinged to a plurality of connecting rods 16 at the end away from the hydraulic pipe 6. Each connecting rod 16 is connected to a corresponding conductive pad 3, and the connecting rod 16 and the conductive pad 3 are also hinged. When the piston rod 5 moves under the pressure change in the hydraulic pipe 6, the piston rod 5 moves by changing the direction of the force along the connecting rods 16, thereby moving the conductive pad 3 along an axis perpendicular to the contact point 14 and the operating button 15 via the connecting rods 16.
[0031] The control lever 1 is also provided with a limiting frame 7 and a fixed bracket 8. One end of the fixed bracket 8 is fixedly installed on the inner wall of the control lever 1, and the other end is slidably connected to the sliding groove provided on the limiting frame 7. The limiting frame 7 is sleeved on the outer periphery of the conductive pad 3 to fix the conductive pad 3. The limiting frame 7 is connected to the connecting rod 16 so that the conductive pad 3 will not affect the adjacent conductive pad 3 during the movement. The fixed bracket 8 is used to ensure that the conductive pad 3 can only move in a direction perpendicular to the axis of the contact point 14 and the operation button 15.
[0032] In some other specific embodiments, the control lever 1 is also provided with a limiting member 17 on its side. The limiting member 17 has a C-shaped structure. The self-locking button 2 is located inside the limiting member 17, so that when the trainee operates the self-locking button 2, he can directly and accurately pass his hand through the limiting member 17, and avoid the inability to accurately press the self-locking button 2 due to shaking during the pressing process.
[0033] In this embodiment, the operation button 15 can be located at the top of the joystick 1 or on the side of the joystick 1.
[0034] In this embodiment, the operation method of the flight training control device is as follows: The trainee inserts his hand into the limiting member 17 set on the control stick 1, presses the self-locking button 2 to enter the connected hydraulic pipe 6, and changes the internal pressure in the hydraulic pipe 6 due to the liquid (or gas) filling it, thereby pushing the piston rod 5 forward. Due to the limiting bracket 7 on the outer periphery of the conductive pad 3 by the fixed bracket 8, the piston rod 5 drives the conductive pad 3 to move along the length direction of the conductive pad 3 through the connecting rod 16 (or directly). When the self-locking button 2 is pressed to the maximum extent, it stops moving. The through hole 13 set on the conductive pad 3 moves to be located between the contact point 14 and the operation button 15. At this time, pressing the operation button 15 can make the operation button 15 and the contact point 14 conduct. When the trainee releases the self-locking button 2, the self-locking button 2 exits the hydraulic pipe 6, and the liquid (or gas) in the hydraulic pipe 6 returns to the self-locking button 2. The piston rod 5 moves in the opposite direction under the action of the reset component 4, which drives the conductive pad 3 to move accordingly. The through hole 13 deviates from the contact 14 and the operation button 15. At this time, it is impossible to make the operation button 15 conduct with the contact 14 by pressing the operation button 15, thus completing the reset.
[0035] Example 2
[0036] See Figure 2 In this embodiment, the control device further includes a telescopic rod 9 sleeved outside the control stick 1. The telescopic rod 9 is externally connected to the base 11 via a soft rubber sleeve 10. The trainee can adjust the height of the control stick 1 via the telescopic rod 9 and simulate controlling the aircraft's attitude in flight by operating the self-locking button 2 and the operation button 15 on the control stick 1. Shock-absorbing elastic elements 12 are provided between the inner wall of the soft rubber sleeve 10 and the outer periphery of the telescopic rod 9, at the bottom of the control stick 1, and inside the telescopic rod 9 to reduce stress loss during operation. In this application, the shock-absorbing elastic element 12 is a spring.
[0037] Furthermore, a hydraulic adjustment component is installed at the bottom of the internal mounting cavity of the telescopic rod 9. This allows for adjustment of the telescopic rod 9's length according to the trainee's arm length, controlling the overall length of the telescopic rod 9 and the control lever 1 exposed outside the base 11 and soft rubber sleeve 10. This prevents fatigue for different trainees due to varying arm lengths during prolonged operation. The hydraulic adjustment component in this application can be a hydraulic lifting cylinder, a structure well-known to those skilled in the art and will not be described further here.
[0038] Specific application examples:
[0039] Before actual flight, pilots need to conduct numerous flight training simulations to simulate the operation of the aircraft's control stick 1 and become familiar with the operation procedures of different operation buttons 15. Taking the flight training control device of this utility model as an example, the specific operation process during flight training is as follows:
[0040] Step 1: Adjust the length of the telescopic rod 9 according to the trainee's arm length so that the height of the control lever 1 matches the trainee's height;
[0041] Step 2: The trainee puts his hand into the limiting part 17 and presses the self-locking button 2. The self-locking button 2 enters the connected hydraulic pipe 6, which in turn pushes the piston rod 5 forward, causing the conductive pad 3 to move along its length. The through hole 13 moves to be located between the contact 14 and the operation button 15. At this time, pressing the operation button 15 can make the operation button 15 and the contact 14 conduct.
[0042] Step 3: The trainee releases the self-locking button 2, which exits the hydraulic pipe 6. The liquid (or gas) in the hydraulic pipe 6 returns to the self-locking button 2, causing the conductive pad 3 to move in the opposite direction. The through hole 13 deviates from the contact 14 and the operation button 15. At this time, it is impossible to make the operation button 15 connect with the contact 14 by pressing the operation button 15, thus completing the reset.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
