[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] refer to Figures 1 to 8 The present invention discloses the following embodiments:

[0028] A helicopter rotor simulation structure includes a base 1, a plurality of simulated rotor blades 2 (as shown in the figure, 5 blades) bolted to the base 1, and a central column 3 disposed on the base 1. A plurality of tension ropes 4 are disposed on the central column 3, the other end of each tension rope 4 being connected to the simulated rotor blade 2 and applying an oblique tension to the simulated rotor blade 2. The tension ropes 4 extend from the central column 3 towards the simulated rotor blade 2 and are connected to the simulated rotor blade 2 to apply an oblique tension to the simulated rotor blade 2, thereby preventing the simulated rotor blade 2 from breaking due to gravity during disassembly, assembly, and simulation.

[0029] On the base 1, around the central column 3, are a plurality of take-up boxes 6 (5 in total), corresponding to the number of simulated blades 2. Each take-up box 6 contains a tensioning mechanism. One end of the tensioning rope 4 passes through the take-up box 6 and is connected to the tensioning mechanism. Specifically, the tensioning mechanism includes an intermediate shaft 7 located inside the take-up box 6. A winding seat 8 is mounted on the intermediate shaft 7. The tensioning rope 4 is connected to the winding seat 8. A coil spring 9 is positioned between the winding seat 8 and the intermediate shaft 7, allowing the tensioning rope 4 to wind around the winding seat 8. Through the cooperation of the intermediate shaft 7, the winding seat 8, and the coil spring 9, the tensioning rope 4 can maintain a taut state. Simultaneously, during the assembly, disassembly, and simulation of the simulated blades 2, the length of the tensioning rope 4 can be adjusted, or in other words, it has an automatic take-up and release function. This allows for adjustment of tension or maintenance of tension during the movement of the simulated blades 2, ensuring appropriate tension. Moreover, adjustment via the coil spring 9 requires no external power, making the structure simpler and more reliable.

[0030] As shown in the figure, the take-up box 6 is provided with two groups of the tensioning mechanism, and each of the simulation oar 2 is connected with two tensioning ropes 4; the tensioning ropes 4 pulled out from the take-up box 6 are connected with the same simulation oar 2, and the connection points are respectively at the positions of one third and two thirds of the length of the simulation oar 2.

[0031] The upper end of the center column 3 is provided with a steering seat 10, and the steering seat 10 is provided with a steering shaft 5, wherein the tensioning rope 4 is pulled out upward by the take-up box 6, passes around the steering shaft 5, and is then connected with the simulation oar 2; an arc-shaped guide groove 15 is arranged on the side wall of the steering shaft 5, so as to guide the tensioning rope 4 to be connected with the simulation oar 2, and prevent the tensioning rope 4 from slipping off or deviating from the correct path.

[0032] The simulation oar 2 comprises a connecting framework 11 connected with the base 1 and a skin arranged on the surface of the connecting framework 11, wherein the connecting framework 11 is made of a carbon fiber square tube, so as to reduce the self weight of the simulation oar 2, and meanwhile, the carbon fiber square tube has the advantage of high strength, so that the embodiment can have the beneficial effects of weight and rigidity.

[0033] The connecting framework 11 is provided with a mounting seat 12, the mounting seat 12 is provided with a connecting lug seat 13, and the other end of the tensioning rope 4 is provided with a hanging ring 14 for connecting the connecting lug seat 13; the structure is simple, easy to produce and manufacture, and the connecting mode is simple and convenient.

[0034] Finally, it should be noted that: the above implementation cases are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing implementation cases, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing implementation cases, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the present application.
