Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of takeoff and landing simulation devices, and in particular to a multi-mode takeoff and landing simulation device for an eVTOL aircraft. Background Technology
[0002] Electric vertical takeoff and landing (eVTOL) aircraft, also known as electric vertical takeoff and landing aircraft, are aircraft that are driven by electric motors and have vertical takeoff and landing capabilities. They can take off and land without a runway. The motors are driven by electric power, which can include different energy forms such as batteries and fuel cells.
[0003] In the prior art, Chinese Patent No. CN218038336U discloses a simulation device for training the take-off and landing process of a helicopter. The driving component includes a first cylinder and a second cylinder fixedly installed in the mounting platform. This simulation device for training the take-off and landing process of a helicopter is conducive to realizing all-round adjustment of the angle of the take-off and landing platform, which can enhance the training intensity and improve the training effect. However, in practical applications, there are also existing vertical take-off and landing simulation devices for eVTOL aircraft. The angle deviation measurement during vertical take-off and landing of the aircraft only presents the final result and cannot intuitively observe the angle change during the vertical take-off and landing process. This has a certain interference with the analysis of the results of multi-mode take-off and landing simulation tests of the aircraft, which leads to a large difference between the analysis of the differences between the multi-mode take-off and landing of the aircraft and the actual results. Therefore, we disclose a multi-mode take-off and landing simulation device for eVTOL aircraft. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a multi-mode take-off and landing simulation device for eVTOL aircraft, so as to solve the problem of not being able to intuitively observe the angle changes during the vertical take-off and landing process of the aircraft.
[0005] Based on the above objectives, this utility model provides a multi-mode takeoff and landing simulation device for an eVTOL aircraft, including a takeoff and landing simulation platform. Several connecting platforms are rotatably connected to the top of the simulation platform. The upper ends of the connecting platforms extend through the simulation platform to its exterior. A first fixed frame is fixedly connected to the top of the connecting platforms. A steering shaft is rotatably connected to the middle of the first fixed frame. A connecting sleeve is fixedly connected to the middle of the steering shaft. A connecting rod is slidably connected to the inner cavity of the connecting sleeve. A universal joint is movably engaged at one end of the connecting rod extending out of the inner cavity of the connecting sleeve. A simulated aircraft is fixedly connected to the top of the universal joint. A first angle turntable is fixedly connected to one end of the steering shaft. Several annularly distributed first push blocks are rotatably connected to the outside of the first angle turntable. The external fixed connection of the angle turntable includes several first spring pieces and first baffles, which are located on both sides of the first push block. One end of the first spring piece is fixedly connected to the first push block. A second fixed frame is provided on both sides of the first fixed frame. Two slide rails are fixedly connected to the top of the connecting platform. The slide rails are slidably connected to the second fixed frame. A second angle turntable is rotatably connected to the upper end of the second fixed frame. Several second push blocks are equidistantly distributed in a ring on the outside of the second angle turntable. Several second spring pieces and second baffles are fixedly connected to the outside of the second angle turntable. The second spring pieces and second baffles are located on both sides of the second push block. One end of the second spring piece is fixedly connected to the second push block. The second push block is adapted to the first push block.
[0006] Preferably, both the second push block and the first push block are inclined relative to the horizontal plane, and the first push block is provided with a second push block on both sides of the first push block. The first push block and the second push block are respectively distributed in a ring around the first angle turntable and the second angle turntable.
[0007] Preferably, the first baffle is attached to one side of the first push block, the second baffle is attached to one side of the second push block, and the first spring piece and the second baffle at the mating point of the first push block and the second push block are respectively located above the first baffle and below the second push block.
[0008] Preferably, the connecting platform is a T-shaped platform, and a number of equidistant strips are fixedly connected to the top of the take-off and landing simulation platform. The strips are distributed around the connecting platform, and an indicator strip is fixedly connected to the outer wall of the connecting platform. The indicator strip is located above the strips.
[0009] Preferably, a first fixing plate is fixedly connected to one side of the second fixing frame, and a second fixing plate is fixedly connected to one side of the slide rail. A limit rod is slidably connected to the upper end of the second fixing plate. The limit rod is fixedly connected to the first fixing plate, and a limit pin is movably engaged in the middle of the limit rod. The limit pin is located between the first fixing plate and the second fixing plate and is in contact with the second fixing plate.
[0010] Preferably, both the slide rail and the limiting pin are T-shaped.
[0011] The beneficial effects of this utility model are as follows: The connecting platform restricts the position of the steering shaft through the first fixed frame. After the simulated aircraft moves, the connecting rod and connecting sleeve move through the universal joint, causing the steering shaft and connecting platform to move. The position of the first angle turntable is fixed by the steering shaft, so that the first angle turntable restricts the position of the first push block. The rotation direction and rotation distance of the first push block are restricted by the cooperation of the first spring and the first baffle. The connecting platform restricts the position of the second fixed frame through the slide rail, and the rotation of the second angle turntable is restricted by the second fixed frame, so that the second angle turntable restricts the position of the second push block. The second spring and the second baffle cooperate to restrict the second push block. The rotation angle and rotation distance are adapted to the first push block through the second push block. When the steering shaft and the first angle turntable drive the first push block to rotate and engage with the second push blocks on both sides, the second push blocks on both sides rotate or stop according to the rotation direction of the first push block. This allows the staff to determine which side the simulated aircraft deviates from during takeoff and landing by observing which side of the second angle turntable is rotating on the steering shaft. Furthermore, by observing the angle of the rotating second angle turntable, the staff can intuitively observe how much the aircraft has deviated during takeoff and landing. This facilitates the staff's comparison of the differences between the various takeoff and landing modes of the aircraft, improves the accuracy of the analysis results, and enhances the analysis of the simulation test.
[0012] The second fixed frame, the first fixed plate, and the limiting rod are fixed relative to each other, so that the limiting pin and the second fixed plate cooperate to restrict the limiting rod from moving to one side of the second fixed plate, thereby restricting the second fixed frame from moving to one side of the second fixed plate. This ensures that the matching position of the second push block and the first push block is stable. After the simulation is over, the limiting pin is removed and the second fixed frame is moved, so that the second angle turntable can rotate back to its original position for easy use next time. The operation is convenient. Attached Figure Description

[0022] like Figures 1-4As shown, a multi-mode takeoff and landing simulation device for an eVTOL aircraft includes a takeoff and landing simulation platform 1. Several connecting platforms 2 are rotatably connected to the top of the platform 1. The upper ends of the connecting platforms 2 extend through the platform 1 to the outside of it.

One end of the first spring piece 11 is fixedly connected to the first push block 10. A second fixed frame 13 is provided on both sides of the first fixed frame 3. Two slide rails 21 are fixedly connected to the top of the connecting platform 2. The slide rails 21 are slidably connected to the second fixed frame 13. A second angle turntable 14 is rotatably connected to the upper end of the second fixed frame 13. A plurality of second push blocks 15 are equidistantly distributed in a ring on the outside of the second angle turntable 14. A plurality of second spring pieces 16 and second baffles 17 are fixedly connected to the outside of the second angle turntable 14. The second spring pieces 16 and second baffles 17 are respectively located on the second push block 10. On both sides of 5, one end of the second spring piece 16 is fixedly connected to the second push block 15. The second push block 15 is adapted to the first push block 10. Both the second push block 15 and the first push block 10 are inclined relative to the horizontal plane. The first push block 10 and the second push block 15 are provided on both sides of the first push block 10. The first push block 10 and the second push block 15 are respectively distributed in a ring around the first angle turntable 9 and the second angle turntable 14. The first baffle 12 is attached to one side of the first push block 10, and the second baffle 17 is attached to one side of the second push block 15. The first spring piece 11 and the second baffle 17 at the matching position of the first push block 10 and the second push block 15 are respectively located above the first baffle 12 and below the second push block 15. The first baffle 12 is attached to one side of the first push block 10, and the second baffle 17 is attached to the second push block 15. One side of the push block 15 is attached. The first spring piece 11 and the second baffle 17 at the mating points of the first push block 10 and the second push block 15 are respectively located above the first baffle 12 and below the second push block 15. The connecting platform 2 is a T-shaped platform. Several sets of equidistant strips are fixedly connected to the top of the landing simulation platform 1. The strips are distributed around the connecting platform 2. An indicator strip is fixedly connected to the outer wall of the connecting platform 2. The indicator strip is located above the strips. In use, the top of the landing simulation platform 1 is rotatably connected to several connecting platforms 2, so that the landing simulation platform 1 fixes the position of the connecting platforms 2. The upper end of the connecting platform 2 passes through the landing simulation platform 1 to the outside of the landing simulation platform 1. The top of the connecting platform 2 is fixedly connected to the first fixing frame 3. The middle of the first fixing frame 3 is rotatably connected to the steering shaft 8.The connecting platform 2 restricts the position of the steering shaft 8 via the first fixed frame 3. A connecting sleeve 4 is fixedly connected to the middle of the steering shaft 8. A connecting rod 5 is slidably connected to the inner cavity of the connecting sleeve 4. One end of the connecting rod 5 extending out of the inner cavity of the connecting sleeve 4 is movably engaged with a universal joint 7. The top end of the universal joint 7 is fixedly connected to a flight simulator 6. When the flight simulator 6 moves, it will drive the connecting rod 5 and the connecting sleeve 4 to move via the universal joint 7, thereby causing the steering shaft 8 and the connecting platform 2 to move. A first angle turntable 9 is fixedly connected to one end of the steering shaft 8. Several first push blocks 10 are rotatably connected to the outside of the first angle turntable 9, so that the steering shaft 8 fixes the position of the first angle turntable 9, and the first angle turntable 9 restricts the position of the first push blocks 10. A number of first spring plates 11 and first baffles 12 are fixedly connected to the outside of the angle turntable 9. The first spring plates 11 and first baffles 12 are located on both sides of the first push block 10. One end of the first spring plate 11 is fixedly connected to the first push block 10, so that the first spring plate 11 and the first baffle 12 cooperate to limit the rotation direction and rotation distance of the first push block 10. Second fixed frames 13 are provided on both sides of the first fixed frame 3. Two slide rails 21 are fixedly connected to the top of the connecting platform 2. The slide rails 21 are slidably connected to the second fixed frames 13, so that the connecting platform 2 limits the position of the second fixed frames 13 through the slide rails 21. A second angle turntable 14 is rotatably connected to the upper end of the second fixed frame 13. A number of second push blocks 15 are rotatably connected to the outside of the second angle turntable 14. The second angle turntable 14 is externally fixedly connected with several second spring pieces 16 and second baffles 17. The second spring pieces 16 and second baffles 17 are respectively located on both sides of the second push block 15. One end of the second spring piece 16 is fixedly connected to the second push block 15, so that the second fixing frame 13 restricts the rotation of the second angle turntable 14, and the second angle turntable 14 restricts the position of the second push block 15. The second spring pieces 16 and second baffles 17 cooperate to restrict the rotation angle and rotation distance of the second push block 15. Furthermore, the second push block 15 is adapted to the first push block 10, so that when the steering shaft 8 and the first angle turntable 9 drive the first push block 10 to rotate and engage with the second push blocks 15 on both sides, the second push blocks 15 on both sides rotate or... The system stops, allowing operators to determine the direction the simulator 6 deviates during takeoff and landing by observing which side of the second angle turntable 14 is rotating on the steering axis 8. This allows for direct observation of the angle of deviation during takeoff and landing, facilitating comparison of different takeoff and landing modes and improving the accuracy of simulation analysis. Both the second push block 15 and the first push block 10 are tilted relative to the horizontal plane, with second push blocks 15 on both sides of the first push block 10. These push blocks are arranged in a ring around the first and second angle turntables 9 and 14, respectively, ensuring that only one side of the second push block 15 rotates when the first push block 10 rotates.To facilitate observation by staff during testing, the first baffle 12 is attached to one side of the first push block 10, and the second baffle 17 is attached to one side of the second push block 15. The first spring piece 11 and the second baffle 17 at the mating points of the first push block 10 and the second push block 15 are respectively located above the first baffle 12 and below the second push block 15. This arrangement ensures that when the first push block 10 rotates to engage with the second push block 15, both the first push block 10 and the second push block 15 are restricted in their rotation angles, thus allowing the second push block 10 to... The first push block 10 moves the second angle turntable 14 downwards, causing it to rotate. Conversely, on the other side of the first push block 10, the second push block 15 is pushed by the first push block 10 to press against the second spring 16, preventing the first push block 10 from moving the second push block 15. This prevents the second angle turntable 14 from rotating. The T-shaped connecting platform 2 ensures a stable connection between the landing simulation platform 1 and the connecting platform 2. Several equidistant strips are fixedly connected to the top of the landing simulation platform 1, surrounding the connecting platform 2. Indicator strips are fixedly connected to the outer wall of the connecting platform 2, positioned above the strips. This allows operators to determine the rotation angle of the connecting platform 2 based on the direction of the indicator strips, facilitating observation.
[0023] As a preferred embodiment of this example, Figure 3 and Figure 4As shown, a first fixing plate 18 is fixedly connected to one side of the second fixing frame 13, and a second fixing plate 20 is fixedly connected to one side of the slide rail 21. A limit rod 19 is slidably connected to the upper end of the second fixing plate 20. The limit rod 19 is fixedly connected to the first fixing plate 18, and a limit pin 22 is movably engaged in the middle of the limit rod 19. The limit pin 22 is located between the first fixing plate 18 and the second fixing plate 20 and is in contact with the second fixing plate 20. Both the slide rail 21 and the limit pin 22 are T-shaped. The first fixing plate 18 is fixedly connected to one side of the second fixing frame 13, and the second fixing plate 20 is fixedly connected to one side of the slide rail 21. The limit rod 19 is slidably connected to the upper end of the second fixing plate 20, and the limit rod 19 is fixedly connected to the first fixing plate 18. The limit pin 22 is movably engaged in the middle of the limit rod 19. The limiting pin 22 is located between the first fixing plate 18 and the second fixing plate 20 and is in contact with the second fixing plate 20, so that the second fixing frame 13, the first fixing plate 18 and the limiting rod 19 are relatively fixed. The limiting pin 22 and the second fixing plate 20 work together to restrict the limiting rod 19 from moving to one side of the second fixing plate 20, thereby restricting the second fixing frame 13 from moving to one side of the second fixing plate 20, ensuring that the matching position of the second push block 15 and the first push block 10 is stable. After the simulation is over, the limiting pin 22 is removed and the second fixing frame 13 is moved, so that the second angle turntable 14 can rotate back to its original position for easy use next time. The operation is convenient. Since both the slide rail 21 and the limiting pin 22 are T-shaped, the connection between the slide rail 21 and the second fixing frame 13 is stable, and the limiting pin 22 is easy to remove.
