Description

Technical Field

[0001] This invention belongs to the field of aircraft control simulation technology, specifically referring to a flight simulation teaching device. Background Technology

[0002] Older aircraft and some modern small aircraft were pulled by wires (steel wires), known as fly-by-wire flight control. Later, hydraulic flight control emerged, which uses liquid (usually oil) to operate the control surfaces. In both of these control methods, the air resistance acting on the control surfaces is fed back to the control stick or pedals. Therefore, when the speed is high or a rapid response is required, a greater amount of force is needed to operate it.

[0003] Although modern advanced aircraft control systems use fly-by-wire or fly-by-light control, they still provide simulated force feedback to the control stick or pedals, thus simulating the "feel" of direct operation and giving operators more confidence in piloting the aircraft.

[0004] During training simulations, the simulator also needs to have this force feedback. However, since the simulator is not connected to a real machine, although it can adjust the resistance based on speed information, it cannot recognize the "rapid response" that the driver wants to make. Summary of the Invention

[0005] In response to the above situation and to overcome the shortcomings of the prior art, this invention proposes a flight simulation teaching device that can simulate operational resistance from two dimensions: aircraft speed and operating speed. In order to detect the movement speed of the operating handle itself, this invention creatively proposes a speed-sensing variable resistance mechanism. By using a flow-blocking orifice that only allows liquid to flow slowly, the sliding resistance increases with the increase of sliding speed, thereby achieving the technical effect that the operational resistance increases with the increase of operating speed.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a flight simulation teaching device, including a directional handle mechanism, a speed-sensitive variable drag mechanism and an active variable drag mechanism. The speed-sensitive variable drag mechanism is located at the bottom of the directional handle mechanism, and the active variable drag mechanism is located below the directional handle mechanism.

[0007] Furthermore, the direction handle mechanism includes a limiting component and a handle component, the handle component being rotatably disposed in the limiting component; the limiting component includes a flat plate and an annular ball socket, the flat plate having a clearance hole, the annular ball socket being disposed directly below the clearance hole, the annular ball socket having a ball socket support leg, and the annular ball socket being fixedly connected to the bottom surface of the flat plate through the ball socket support leg.

[0008] Preferably, the handle assembly includes a ball joint body and an operating handle. The ball joint body is provided with an upper ball joint support rod and a lower ball joint support rod. The operating handle is fixed to the upper ball joint support rod and is provided with a handle button.

[0009] The direction of flight of the aircraft can be simulated by rotating the control handle, while the buttons on the control handle can be used for other operations.

[0010] Furthermore, the speed-sensing variable resistance mechanism includes a fixed liquid storage tank and a flange. The fixed liquid storage tank is filled with liquid, and the flange is slidably engaged within the flange. The flange is provided with flow-blocking holes.

[0011] Preferably, the speed-sensitive variable resistance mechanism further includes a lifting rod and a lifting rope. The lifting rod is fixed to the flange and is slidably engaged in the fixed liquid storage tank. The lifting rope is located between the lifting rod and the lower support rod of the ball joint. When the lower support rod of the ball joint swings, the flange and the lifting rod will slide upward under the action of the lifting rope.

[0012] When the operating handle rotates around the center of the ball joint body, the lower support rod of the ball joint will pull the flange and the lifting rod upward through the lifting rope. Since only small flow obstruction holes on the flange allow liquid to pass through, there will be resistance to the sliding of the flange in the fixed liquid storage tank. Furthermore, due to the characteristics of the fluid, the faster the flange slides, the greater the sliding resistance will be. This achieves the technical effect that the operating resistance increases with the increase of the operating speed.

[0013] Furthermore, the active variable resistance mechanism includes a fixed resistance ring assembly, a movable resistance ring assembly, an active control assembly, and a preload adjustment assembly. The fixed resistance ring assembly is fixed to the bottom of the flat plate, the movable resistance ring assembly is slidably disposed on the annular ball socket, the active control assembly is disposed at the bottom of the flat plate, and the preload adjustment assembly is disposed at the bottom of the flat plate.

[0014] Preferably, the fixed resistance ring assembly includes an L-shaped fixing frame and a fixed resistance ring. The L-shaped fixing frame is fixed to the bottom of the flat plate, and the fixed resistance ring is fixed to the L-shaped fixing frame. The fixed resistance ring is provided with a semi-annular fork portion, which is engaged at both ends of the annular ball socket. The ball-and-socket body and the inner wall of the fixed resistance ring are in sliding contact.

[0015] As a further preferred embodiment of the present invention, the movable resistance ring assembly includes a movable resistance ring and a rotating sleeve. The movable resistance ring is provided with a semi-annular fork portion two. The movable resistance ring is engaged and slidably disposed on an annular ball socket through the semi-annular fork portion two. The rotating sleeve is fixedly connected to the movable resistance ring.

[0016] The fixed resistance ring remains stationary, while the operating resistance of the operating handle can be changed by altering the squeezing force exerted by the movable resistance ring on the ball joint body.

[0017] Furthermore, the active control component includes an adjusting motor and an adjusting lead screw. The adjusting motor is fixed to the bottom of the flat plate, one end of the adjusting lead screw is fixed to the output shaft of the adjusting motor, and the other end of the adjusting lead screw is located in the rotating sleeve. The adjusting lead screw and the rotating sleeve are in sliding contact.

[0018] Preferably, the preload adjustment assembly includes a nut groove, an adjusting nut, and a preload spring. The nut groove is fixed to the bottom of the flat plate, the adjusting nut is engaged and slidably disposed in the nut groove, the adjusting nut and the adjusting screw are threadedly connected, and the preload spring is disposed between the adjusting nut and the rotating sleeve.

[0019] The adjusting motor can control the rotation of the adjusting screw according to the speed parameters of the simulated aircraft, thereby adjusting the position of the adjusting nut, and thus actively changing the compression of the preload spring and the squeezing force applied to the ball joint body by the semi-annular fork section.

[0020] As a further preferred embodiment of the present invention, the lifting rope is made of a non-stretchable flexible material.

[0021] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The direction of flight of the aircraft can be simulated by rotating the control handle, while the handle buttons on the control handle can be used for other operations.

[0022] (2) When the operating handle rotates with the ball center of the ball screw body as the origin, the lower support rod of the ball screw will pull the flange and the lifting rod up through the lifting rope. Since only the small flow obstruction hole on the flange can allow the liquid to pass through, there will be resistance to the sliding of the flange in the fixed liquid storage tank. Furthermore, due to the characteristics of the fluid, the faster the flange slides, the greater the sliding resistance will be, thus achieving the technical effect that the operating resistance increases with the increase of the operating speed.

[0023] (3) The fixed resistance ring is fixed in place, and the operating resistance of the operating handle can be changed by changing the squeezing force of the movable resistance ring on the ball strand body.

[0024] (4) The motor can control the rotation of the adjusting screw according to the speed parameters of the simulated aircraft, thereby adjusting the position of the adjusting nut, and thus actively changing the compression of the preload spring and the squeezing force applied to the ball joint body by the semi-annular fork.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1-10 As shown, the present invention proposes a flight simulation teaching device, including a steering handle mechanism 1, a speed-sensitive variable drag mechanism 2, and an active variable drag mechanism 3. The speed-sensitive variable drag mechanism 2 is located at the bottom of the steering handle mechanism 1, and the active variable drag mechanism 3 is located below the steering handle mechanism 1.

[0031] The steering handle mechanism 1 includes a limiting component 4 and a handle component 5. The handle component 5 is rotatably disposed in the limiting component 4. The limiting component 4 includes a flat plate 6 and an annular ball socket 7. The flat plate 6 is provided with a clearance hole 10. The annular ball socket 7 is located directly below the clearance hole 10. The annular ball socket 7 is provided with a ball socket support leg 11. The annular ball socket 7 is fixed to the bottom surface of the flat plate 6 through the ball socket support leg 11.

[0032] The handle assembly 5 includes a ball joint body 8 and an operating handle 9. The ball joint body 8 is provided with an upper ball joint support rod 12 and a lower ball joint support rod 13. The operating handle 9 is fixed to the upper ball joint support rod 12 and is provided with a handle button 14.

[0033] The direction of flight of the aircraft can be simulated by rotating the control handle 9, while the handle button 14 on the control handle 9 can be used for other operations.

[0034] The active variable resistance mechanism 3 includes a fixed resistance ring assembly 20, a movable resistance ring assembly 21, an active control assembly 22, and a preload adjustment assembly 23. The fixed resistance ring assembly 20 is fixed to the bottom of the flat plate 6, the movable resistance ring assembly 21 is slidably disposed on the annular ball socket 7, the active control assembly 22 is disposed at the bottom of the flat plate 6, and the preload adjustment assembly 23 is disposed at the bottom of the flat plate 6.

[0035] The fixed resistance ring assembly 20 includes an L-shaped fixing frame 24 and a fixed resistance ring 25. The L-shaped fixing frame 24 is fixed to the bottom of the flat plate 6, and the fixed resistance ring 25 is fixed to the L-shaped fixing frame 24. The fixed resistance ring 25 is provided with a semi-annular fork portion 33, which is engaged at both ends of the annular ball socket 7. The ball-and-socket body 8 and the inner wall of the fixed resistance ring 25 are in sliding contact.

[0036] The movable resistance ring assembly 21 includes a movable resistance ring 26 and a rotating sleeve 27. The movable resistance ring 26 is provided with a semi-annular fork portion 34. The movable resistance ring 26 is engaged and slidably disposed on the annular ball socket 7 through the semi-annular fork portion 34. The rotating sleeve 27 is fixedly connected to the movable resistance ring 26.

[0037] The fixed resistance ring 25 remains stationary, while the operating resistance of the operating handle 9 can be changed by altering the squeezing force of the movable resistance ring 26 on the ball-and-socket body 8.

[0038] The active control component 22 includes an adjusting motor 28 and an adjusting screw 29. The adjusting motor 28 is fixed to the bottom of the flat plate 6. One end of the adjusting screw 29 is fixed to the output shaft of the adjusting motor 28, and the other end of the adjusting screw 29 is located in the rotating sleeve 27. The adjusting screw 29 and the rotating sleeve 27 are in sliding contact.

[0039] The preload adjustment assembly 23 includes a nut groove 30, an adjusting nut 31, and a preload spring 32. The nut groove 30 is fixed to the bottom of the flat plate 6. The adjusting nut 31 is engaged and slidably disposed in the nut groove 30. The adjusting nut 31 is threadedly connected to the adjusting screw 29. The preload spring 32 is disposed between the adjusting nut 31 and the rotating sleeve 27.

[0040] The adjusting motor 28 can control the rotation of the adjusting screw 29 according to the speed parameters of the simulated aircraft, thereby adjusting the position of the adjusting nut 31, and thus actively changing the compression of the preload spring 32 and the squeezing force applied to the ball joint body 8 by the semi-annular fork section 34.

[0041] The lifting rope 18 is made of a non-stretchable flexible material.

[0042] The speed-sensitive variable resistance mechanism 2 includes a fixed liquid storage tank 15 and a flange 16. The fixed liquid storage tank 15 is filled with liquid, and the flange 16 is engaged and slidably disposed in the flange 16. The flange 16 is provided with a flow obstruction hole 19.

[0043] The speed-sensitive variable resistance mechanism 2 also includes a lifting rod 17 and a lifting rope 18. The lifting rod 17 is fixed to the flange 16 and is engaged and slidably disposed in the fixed liquid storage tank 15. The lifting rope 18 is disposed between the lifting rod 17 and the lower support rod 13 of the ball screw. When the lower support rod 13 of the ball screw swings, the flange 16 and the lifting rod 17 will slide upward under the action of the lifting rope 18.

[0044] When the operating handle 9 rotates around the center of the ball joint body 8, the lower support rod 13 of the ball joint will pull the flange 16 and the lifting rod 17 upward through the lifting rope 18. Since only the small flow obstruction hole 19 on the flange 16 allows liquid to pass through, there will be resistance to the sliding of the flange 16 in the fixed liquid storage tank 15. Furthermore, due to the characteristics of the fluid, the faster the flange 16 slides, the greater the sliding resistance will be. This achieves the technical effect that the operating resistance increases with the increase of the operating speed.

[0045] In practical use, the user first needs to control the flight direction by rotating the operating handle 9, and perform other operations on the aircraft by using the handle button 14. The annular ball socket 7 limits the ball-and-socket body 8, so that the ball-and-socket body 8 always centers on its own ball center when rotating. The adjusting motor 28 controls its own rotation in real time according to the speed of the simulated aircraft, and adjusts the position of the adjusting nut 31 by adjusting the lead screw 29. The faster the speed of the simulated aircraft, the greater the pre-compression of the pre-tension spring 32 and the greater the operating resistance of the operating handle 9. The slower the speed of the simulated aircraft, the smaller the pre-compression of the pre-tension spring 32 and the smaller the operating resistance of the operating handle 9.

[0046] When the operating handle 9 rotates around the center of the ball joint body 8, the lower support rod 13 of the ball joint will simultaneously pull the flange 16 and the lifting rod 17 upward through the lifting rope 18. Since only the small flow obstruction hole 19 on the flange 16 allows liquid to pass through, there will be resistance to the sliding of the flange 16 in the fixed liquid storage tank 15. Furthermore, due to the characteristics of the fluid, the faster the flange 16 slides, the greater the sliding resistance will be. This achieves the technical effect that the operating resistance increases with the increase of the operating speed.
