[0002] The six-degree-of-freedom motion platform is the core device of the flight simulator. By simulating the six degrees of freedom of an object in three-dimensional space, it provides pilots with realistic motion feedback.

[0003] A search revealed a utility model patent with application number 202220617271.1, entitled "A Six-Degree-of-Freedom Platform Device Based on Weight Reduction Design." This patented device abandons the traditional design of large flat surfaces and heavy plates, retaining only the effective load-bearing parts. It adopts a design using plate welding and bottom reinforcing ribs, and is connected and fixed to the load equipment using high-strength bolt pairs. Based on the specific structure of the load equipment's bottom skid, the connection points between the upper platform and the load equipment's bottom skid are rationally arranged in terms of position and number, ensuring a safe and reliable connection.

[0004] However, because the patented device requires users to move to a relatively high height during the ascent and descent process, it is prone to accidents such as bumps and falls, which affects the safety of the device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a six-degree-of-freedom motion platform device for a flight simulator.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A six-degree-of-freedom motion platform device for a flight simulator includes a base plate. An auxiliary mechanism is provided on the top of the base plate. The auxiliary mechanism includes at least four overlapping movable blocks disposed above the base plate. The bottom of the movable blocks abuts against the top of the base plate. A groove is provided between the top and bottom of the movable blocks. A pressing block is fixedly connected to the inner side wall of the groove, and the length of the pressing block increases sequentially from top to bottom. A movable plate is slidably connected between the two inner walls of the groove, and the bottom of the movable plate extends to the top of the base plate.

[0008] Preferably, the bottom of the base plate has a slot aligned with the slide groove, a motor is fixedly connected to the inner wall of the side of the slot, the output shaft of the motor is fixedly connected to a lead screw, and the other end of the lead screw is rotatably connected to the inner wall of the side of the slot.

[0009] Preferably, a movable block aligned with the moving plate is threaded to the circumferential side of the lead screw, the bottom of the movable block is slidably connected to the bottom inner wall of the slot, the bottom of the moving plate is provided with a telescopic groove, a limit post is slidably connected to the inner wall of the circumferential side of the telescopic groove, and the bottom of the limit post is fixedly connected to the top of the movable block.

[0010] Preferably, a second motor aligned with the slide groove is fixedly connected between the bottom and top of the base plate. A second lead screw is fixedly connected to the output shaft of the second motor. A lifting block is threadedly connected to the circumferential side of the second lead screw. One side of the lifting block is slidably connected to the inner wall of one side of the slide groove.

[0011] Preferably, a limiting groove is provided between the two sides of the moving block, and a top block aligned with the limiting groove is fixedly connected to both sides of the lifting block, and the thickness of the top block decreases from top to bottom, with one side of the top block extending into the interior of the limiting groove.

[0012] Preferably, the bottom of the lifting block is evenly provided with square grooves, and a limiting plate is slidably connected between the two inner walls of the square grooves. The bottom of the limiting plate is fixedly connected to the top of the base plate. Both sides of the moving plate are fixedly connected with sliders aligned with the limiting grooves. The bottom of the sliders is slidably connected to the bottom inner wall of the limiting grooves. A top plate is provided above the base plate and located above the moving block.

[0013] Preferably, a fixed frame is uniformly fixedly connected to the top of the base plate and the bottom of the top plate. A rotating frame is rotatably connected between the two inner walls of the fixed frame. A connecting shaft is rotatably connected between the two sides of the rotating frame.

[0014] Compared with the prior art, this utility model provides a six-degree-of-freedom motion platform device for a flight simulator, which has the following advantages:

[0015] The device is mounted on a horizontal working surface via a base plate using movable blocks. A flight simulator is mounted on top of the top plate. Motor 1 is activated, driving screw 1 to rotate. Screw 1 moves a movable block, which in turn moves a limiting post. The limiting post moves a moving plate, which in turn presses against the pressing block. The pressing block then moves the moving block, causing it to extend between the base and top plates, forming a step for users to ascend and descend. This prevents accidents such as bumps and falls that could occur if users need to move at high heights during ascent and descent, compromising the device's safety. Motor 2 is then activated, driving screw 2 to rotate. Screw 2 moves a lifting block, which in turn moves a top block. The top block then lifts the moving blocks, offsetting them at a certain height. This allows for a more even distribution of the moving blocks between the base and top plates, accommodating users' average stride and improving the device's convenience. During operation, the moving blocks are retracted and overlapped on the base plate and away from the top plate, preventing them from interfering with the top plate's multi-degree-of-freedom adjustment and improving the device's stability.

A movable plate 13 is slidably connected between the two inner walls of the groove 10, and the bottom of the movable plate 13 extends to the top of the base plate 1.

[0022] In this utility model, the bottom of the base plate 1 is provided with a slot 16 aligned with the slide groove 10. A motor 15 is fixedly connected to the inner side wall of the slot 16. The output shaft of the motor 15 is fixedly connected to a lead screw 18. The other end of the lead screw 18 is rotatably connected to the inner side wall of the slot 16.

[0023] The circumferential side of the lead screw 18 is threaded with a movable block 20 that is aligned with the moving plate 13. The bottom of the movable block 20 is slidably connected to the bottom inner wall of the slot 16. The bottom of the moving plate 13 is provided with a telescopic groove. The inner wall of the circumferential side of the telescopic groove is slidably connected with a limit post 19. The bottom of the limit post 19 is fixedly connected to the top of the movable block 20.

[0024] A motor 22, aligned with the slide groove 10, is fixedly connected between the bottom and top of the base plate 1. A lead screw 21 is fixedly connected to the output shaft of the motor 22. A lifting block 12 is threadedly connected to the circumferential side of the lead screw 21. One side of the lifting block 12 is slidably connected to one inner wall of the slide groove 10.

[0025] A limiting groove 14 is provided between the two sides of the moving block 9. Both sides of the lifting block 12 are fixedly connected with a top block 11 aligned with the limiting groove 14. The thickness of the top block 11 decreases from top to bottom. One side of the top block 11 extends into the interior of the limiting groove 14.

[0026] The bottom of the lifting block 12 is evenly provided with square grooves. A limiting plate 23 is slidably connected between the inner walls of the two sides of the square groove. The bottom of the limiting plate 23 is fixedly connected to the top of the base plate 1. Both sides of the moving plate 13 are fixedly connected with sliders aligned with the limiting groove 14. The bottom of the slider is slidably connected to the bottom inner wall of the limiting groove 14. A top plate 8 is provided above the moving block 9 on the top of the base plate 1.

[0027] A fixed frame 2 is evenly fixedly connected to the top of the base plate 1 and the bottom of the top plate 8. A rotating frame 4 is rotatably connected between the two inner walls of the fixed frame 2. A connecting shaft 3 is rotatably connected between the two sides of the rotating frame 4. A rotating column 5 is rotatably connected to the circumferential side of the lower connecting shaft 3.

[0028] Working principle: The device is mounted on a horizontal working surface via the base plate 1, and the flight simulator is mounted on top of the top plate 8. Motor 15 is started, driving the lead screw 18 to rotate. The lead screw 18 moves the movable block 20, which in turn moves the limiting post 19. The limiting post 19 then moves the moving plate 13, which in turn presses against the pressing block 17. The pressing block 17 then moves the moving block 9, causing it to extend between the base plate 1 and the top plate 8, forming a step for the user to ascend and descend. This helps prevent accidents caused by the device requiring users to move at high heights during ascent and descent. In case of collisions, falls, or other accidents that affect the safety of the device, the second motor 22 is started. The second motor 22 drives the second lead screw 21 to rotate, which in turn drives the lifting block 12 to move. The lifting block 12 then drives the top block 11 to move, which in turn drives the moving blocks 9 to rise and stagger them to a certain height. This allows the moving blocks 9 to be more evenly distributed between the base plate 1 and the top plate 8, making it suitable for the average stride of the user and improving the convenience of the device. At the same time, when the device is in operation, the moving blocks 9 are stored and overlapped on the base plate 1 and are not on the top plate 8, preventing the moving blocks 9 from affecting the multi-degree-of-freedom adjustment of the top plate 8 and improving the stability of the device.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
