After executing the command of small lifting amplitude changes for a long time, the lifting mechanism will be greatly worn. At the same time, the lifting mechanism and the equipment have high maintenance requirements. Summary of the invention

DETAILED DESCRIPTION In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0014] like Figure 1-Figure 6The lifting device of a flight simulator shown in the figure includes a first lifting mechanism 1. By setting the first lifting mechanism 1, the up and down lifting of a movable platform 6 can be completed. The top of the first lifting mechanism 1 is fixedly connected to a support table 2, the top of the support table 2 is fixedly connected to a locking plate 3, the top of the locking plate 3 is fixedly connected to a top plate 4, the top of the top plate 4 is inserted and slidably connected with a movable platform 6 for supporting a flight simulator, both ends of one side of the bottom of the top plate 4 are fixedly installed with motors 8 through mounting frames, both sides of the outer wall of the support table 2 are fixedly connected with a pair of fixed blocks 9 that are far away from each other, one side of the fixed block 9 is inserted and rotatably connected with a rotating shaft 10, one side of the rotating shaft 10 is fixedly connected with a cam 12, a connecting shaft 13 is fixedly connected between two adjacent cams 12, and the output ends of the two motors 8 are fixedly connected to the rotating shaft 10. A pulley group 11 is provided between each of the rotating shafts 10, and a pair of abutment plates 15 are fixedly connected to the bottom of the movable platform 6. Through the connection between the pulley group 11 and the connecting shaft 13, the motor 8 can drive the rotating shaft 10 and multiple cams 12 to rotate synchronously after being energized. The cam 12 in a rotating state can lift the movable platform 6, and then can simulate a small amplitude up and down lifting. Through this setting, it can be used in conjunction with the first lifting mechanism 1, and replace the first lifting mechanism 1 to complete a small amplitude lifting action, and can be lifted and lowered at the same time as the first lifting mechanism 1. The two lifting mechanisms each perform the corresponding amplitude lifting work, which is convenient for debugging and maintenance of equipment, can reduce the loss of equipment, and can bring a more realistic and subtle simulated flight experience to the experiencer through the dual lifting instructions.
[0015] Electromagnets 14 are fixedly installed on both sides of the bottom of the top plate 4, and a mounting groove 17 is opened on one side of the contact plate 15. Evenly distributed plug rods 18 are inserted and slidably connected inside the mounting groove 17, and a return spring 19 is sleeved on the outside of the plug rod 18. The end of the plug rod 18 is fixedly connected to a magnetic matching plate 20, and the electromagnet 14 and the magnetic matching plate 20 are magnetically matched. Through this arrangement, when the electromagnet 14 is energized, it can generate magnetic attraction, thereby attracting the magnetic matching plate 20, and causing it to be pulled out of the mounting groove 17 to contact the electromagnet 14, and stuck at the opening of the mounting groove 17 to resist the top wall, thereby providing a fixing force for the movable platform 6, thereby reducing the load-bearing capacity of the cam 12, and when the movable platform 6 is lifted up and down, the electromagnet 14 is de-energized, so that the magnetic matching plate 20 is pulled back to the inside of the mounting groove 17 by the pull of the return spring 19 to complete the reset.
[0016] A slot 16 is provided on the other side of the contact plate 15, and cavities are provided on both sides of the locking plate 3. A number of electric push rods 21 are fixedly installed inside the cavities. The output ends of the electric push rods 21 are fixedly connected to plug plates 23, and the plug plates 23 are adapted to the shapes of the slots 16. Stabilizing plates 22 are fixedly connected to both sides of the outer wall of the locking plate 3, and the plug plates 23 are inserted and slidably connected to the other side of the stabilizing plate 22. The electric push rods 21 can drive the plug plates 23 to be inserted into or pulled out of the slots 16, and then can cooperate with the electromagnet 14, further improving the fixing effect.
[0017] The cam 12 includes a cylinder 24 and a protrusion 25 connected to each other. A cavity is provided on one side of the cylinder 24 away from the protrusion 25. A pair of reset springs 27 are fixedly connected to the inner wall of the cylinder 24. A movable arc plate 26 is fixedly connected to the top of the reset spring 27, and the movable arc plate 26 is located outside the cavity. A pair of opposite buffer springs 28 are fixedly connected to the bottom of the movable arc plate 26, and the buffer springs 28 are fixedly connected to the inner wall of the cylinder 24. A first reinforcing rib 29 and a second reinforcing rib 30 arranged crosswise are fixedly connected between the two buffer springs 28, and the first reinforcing rib 29 and the second reinforcing rib 30 are fixedly connected to the inner wall of the cylinder 24. After the electromagnet 14 fixes the movable platform 6 , driven by the motor 8, the cam 12 rotates to the direction of the protrusion 25. At this time, the electromagnet 14 is powered off, causing the unfixed contact plate 15 to suddenly fall down, and finally collide with the cam 12 below, thereby simulating the feeling of sudden weightlessness. The buffer spring 28 can buffer the impact force of the contact plate 15. The reset spring 27 can further buffer the impact force and play a directional pushing role in the recovery, thereby preventing the movable arc plate 26 from gradually shifting during use. The second reinforcing rib 30 and the first reinforcing rib 29 can support the buffer spring 28 while limiting its excessive deformation. Through this arrangement, the lifting device can simulate the feeling of sudden weightlessness, thereby enriching the simulation experience. The top of the top plate 4 is fixedly connected with a reinforcement plate 5, and the movable platform 6 is inserted and slidably connected to the bottom of the reinforcement plate 5. Through this arrangement, the stability of the movable platform 6 during the up and down movement can be improved.
[0018] Evenly distributed buffer springs 7 are fixedly installed between the movable platform 6 and the reinforcement plate 5. Through this arrangement, resistance can be brought to the up and down lifting of the movable platform 6, and a part of the inertia can be offset, making the lifting process smoother and more fluent, thereby enhancing the user's simulation experience.
[0019] Working principle: After the motor 8 is powered on, it can drive the rotating shaft 10 and the multiple cams 12 to rotate synchronously. The cams 12 in the rotating state can lift up the movable platform 6, and then simulate a small amplitude up and down lifting. Through this setting, it can be used in conjunction with the first lifting mechanism 1, and replace the first lifting mechanism 1 to complete the small amplitude lifting action, and can lift and lower at the same time as the first lifting mechanism 1. The two lifting mechanisms each perform the lifting work of the corresponding amplitude, which is convenient for debugging and maintaining the equipment, and can reduce the loss of the equipment. At the same time, the dual lifting instructions can bring a more realistic and subtle simulated flight experience to the experiencer; After the electromagnet 14 fixes the movable platform 6, the cam 12 rotates to the direction of the protrusion 25 under the drive of the motor 8. At this time, the electromagnet 14 is powered off, causing the unfixed contact plate 15 to suddenly fall down, and finally collide with the cam 12 below, thereby simulating the feeling of sudden weightlessness. The buffer spring 28 can buffer the impact force of the contact plate 15. The reset spring 27 can further buffer the impact force and play a directional pushing role in the recovery process to prevent the movable arc plate 26 from gradually shifting during use. The second reinforcing rib 30 and the first reinforcing rib 29 can support the buffer spring 28 while limiting its excessive deformation. Through this arrangement, the lifting device can simulate the feeling of sudden weightlessness, thereby enriching the simulation experience.
