[0019] Aircraft simulators, through highly integrated hardware systems and advanced simulation technology, provide the aviation industry with a safe, efficient, and low-cost training and R&D platform. Their technological evolution will continue to drive the development of flight safety and the aviation industry.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-3 As shown, this embodiment provides an aircraft simulator with a retractable wheelbase, including a connecting frame 5. One end of the connecting frame 5 is connected to a front nose wheel 1, and the other end of the connecting frame 5 is fixedly connected to a fixed seat 8. A telescopic structure is installed inside the fixed seat 8, and the two ends of the telescopic structure are respectively connected to rear wheels 7. Support members 11 are symmetrically arranged on the rear side of the fixed seat 8. The support members 11 can extend to lift the fixed seat 8 and lift the rear wheels 7 off the ground, thereby realizing the wheelbase adjustment of the two rear wheels 7. A cockpit 6 is provided above the connecting frame 5, and the front nose wheel 1 has a steering function.

[0023] This invention comprises a connecting frame 5 connecting the front nose wheel 1 and the fixed base 8. A telescopic structure is installed within the fixed base 8 to connect the rear running wheels 7. A support member 11 can extend to lift the fixed base 8, allowing the rear running wheels 7 to lift off the ground. The telescopic structure also adjusts the spacing of the rear running wheels 7. A cockpit 6 is located above the connecting frame 5. The front nose wheel 1 has a steering function. This invention achieves rear running wheel 7 spacing adjustment by lifting the fixed base 8 through the support member 11, simulating the flight states of aircraft with different wheelbases. Simultaneously, the retracted rear running wheels 7 save space, facilitating storage and improving convenience. The steering function of the front nose wheel 1 increases the flexibility of the simulation. The cockpit 6 provides operating space for the operator. The overall structure provides a basic framework for the simulator to achieve multiple functions. Furthermore, it features low cost, reliable performance, and strong operability.

[0024] Furthermore, the support member 11 can be a manually adjustable threaded screw structure or a hydraulic cylinder telescopic method, depending on the actual situation.

[0025] Further optimization of the design involves a telescopic structure including a motor 15 fixedly connected to the inner wall of the fixed base 8. The output shaft of the motor 15 is fixedly connected to a second gear 14, which meshes with a first gear 13. A forward and reverse threaded screw 12 passes through the center of the first gear 13. Both ends of the forward and reverse threaded screw 12 extend into telescopic blocks 10 and are threadedly connected to them. The two telescopic blocks 10 are respectively connected to the two rear wheels 7. The output shaft of the motor 15 drives the second gear 14 to rotate, which in turn drives the first gear 13. The first gear 13 then drives the forward and reverse threaded screw 12 to rotate. The forward and reverse threaded screw 12 is threadedly connected to the telescopic blocks 10, causing the two telescopic blocks 10 to move towards or away from each other on the screw 12. The telescopic blocks 10 then move the rear wheels 7 to adjust the wheelbase. This design, using a motor 15 drive, gear transmission, and forward and reverse threaded screw 12 transmission, results in a compact structure with high transmission efficiency. It allows for precise control of the movement distance of the rear wheels 7, achieving accurate wheelbase adjustment and meeting various simulation requirements.

[0026] Further optimization of the design involves a groove 16 within the fixed base 8, where the motor 15, the first gear 13, and the second gear 14 are located. Symmetrical sliding grooves 17 are formed within the fixed base 8, with two telescopic blocks 10 positioned within and slidably connected to the two sliding grooves 17. The groove 16 communicates with the two sliding grooves 17. The groove 16 provides space for gear transmission, while the sliding grooves 17 guide and limit the movement of the telescopic blocks 10, ensuring the stability and accuracy of their movement, enabling the telescopic structure to function normally, and improving the reliability of wheelbase adjustment.

[0027] In a further optimized design, a connecting shaft 9 is rotatably connected to the center of the rear travel wheel 7, and the end of the connecting shaft 9 furthest from the rear travel wheel 7 is fixedly connected to the telescopic block 10. This connection method is simple and reliable, and can directly transmit the movement of the telescopic block 10 to the rear travel wheel 7 to achieve wheel track adjustment. At the same time, the rear travel wheel 7 can rotate around the connecting shaft 9 to ensure driving flexibility.

[0028] The design was further optimized by fixing a mounting base 4 to the top surface of the connecting frame 5, with the cockpit 6 located on top of the mounting base 4. The mounting base 4 provides stable support for the cockpit 6, ensuring its stability during simulator operation, while also facilitating the installation and removal of the cockpit 6 for easy maintenance and replacement.

[0029] Further optimization involves installing a vertical rod 2 on the nose wheel 1. The vertical rod 2 controls the steering of the nose wheel 1. The vertical rod 2 provides the operator with a direct control component, allowing for convenient control of the nose wheel 1's steering, increasing the simulator's operability and flexibility, and better simulating aircraft steering maneuvers.

[0030] The design was further optimized by bolting a solar photovoltaic panel 3 to the top of the pole 2. The solar photovoltaic panel 3 converts solar energy into electrical energy, which is stored in an energy storage device located inside the cockpit 6 and supplies power to the electrical equipment. The solar photovoltaic panel 3 utilizes renewable energy to power the simulator, reducing reliance on traditional energy sources and lowering operating costs. Simultaneously, the energy storage device stores electrical energy, and a voltage regulator and inverter are installed between the energy storage device and the solar photovoltaic panel 3 to ensure efficient and stable system operation. This guarantees that the simulator can still operate normally even with insufficient sunlight, improving the simulator's energy efficiency and endurance.
