Abstract
Description
Technical Field
[0001] This utility model relates to the field of flight simulation training technology, and in particular to a flight training simulation device. Background Technology
[0002] Flight training simulators are commonly used equipment for pilots' daily training. They typically consist of a simulator cabin, interface devices, various instruments, a visual system, and a training computer. The simulator cabin is designed to strictly replicate the layout of a real aircraft cockpit, with instrument panels and controls identical to those in a live aircraft. During training, pilots can practice basic flight operations in the simulator, such as turning on the power switch, pushing or pulling the throttle, and operating the flight stick and rudder. The visual system provides a simulated environment for the trainee, allowing them to learn and master more challenging and dangerous maneuvers.
[0003] Existing flight training simulators are generally fixed to the ground, powered by a six-degree-of-freedom motion platform beneath the simulator cabin, which then simulates takeoff, landing, and other flight missions. However, while trainees can control the simulator's forward and backward movement using the joystick and rudder, in simulated real-flight emergencies such as emergency braking, they rely primarily on seatbelts without limiting the simulator's braking range. If the simulator accelerates excessively, the lack of proper seatbelt fastening can still result in injury to trainees. Therefore, limiting the simulator's braking range to ensure safety during flight simulation is a pressing issue that needs to be addressed. Utility Model Content
[0004] To address the aforementioned problems, this utility model aims to provide a flight training simulation device that facilitates simulated training for pilots and provides secondary protection for pilots in the event of unforeseen circumstances during flight training.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A flight training simulator includes a simulator cabin and a moving mechanism disposed below the simulator cabin.
[0007] A limiting mechanism, located on one side of the simulation chamber, is used to limit the braking range of the simulation chamber;
[0008] The power mechanism is connected to the moving mechanism and is used to drive the moving mechanism to rotate.
[0009] Further defining the above technical solution, the moving mechanism includes a hydraulic platform and hydraulic rods, with the hydraulic rods symmetrically arranged at the four corners of the bottom of the simulation cabin.
[0010] To further define the above technical solution, the hydraulic platform is provided with mounting slots, and the hydraulic rods are rotatably installed in each mounting slot.
[0011] Further defining the above technical solution, the limiting mechanism includes a column, a limiting frame, and a limiting plate, wherein one end of the limiting frame is connected to the column, and the other end is sleeved on the limiting plate.
[0012] As a further definition of the above technical solution, the power mechanism includes a mounting plate, a mounting base, and a servo motor disposed within the mounting base.
[0013] As a further limitation of the above technical solution, the output shaft of the servo motor is connected to the bottom surface of the hydraulic platform.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] First, this utility model is equipped with a hydraulic rod and a hydraulic platform. When the pilot is conducting flight training, as the simulator moves back and forth or rises and falls, the angle of the hydraulic rod is adjusted by rotating it in the mounting groove on the hydraulic platform, and the length of the hydraulic rod is adjusted simultaneously to coordinate with the normal movement of the simulator, thereby facilitating the pilot's flight training.
[0016] Secondly, this utility model is equipped with a column, a limiting frame, and a limiting plate. The limiting plate is connected to the top of the simulator, and the limiting frame is fitted onto the limiting plate. When an emergency occurs during flight training and the pilot performs emergency braking, the limiting frame slides on the limiting plate, thereby limiting the front and rear braking range of the simulator. Furthermore, since the limiting frame has a certain height and the limiting plate is located inside the limiting frame, the lifting height of the simulator can also be limited when the simulator is undergoing lifting simulation training, ensuring the safety of the simulator in the simulated state.
[0017] Third, this utility model is equipped with a mounting plate, a mounting base, and a servo motor. The mounting plate and mounting base can be used to install the entire flight training simulator on the ground. At the same time, since the output shaft of the servo motor built into the mounting base is connected to the bottom surface of the hydraulic platform, when the servo motor works, it can drive the hydraulic platform to rotate, thereby driving the simulator cabin to rotate, thus simulating turning actions during flight. It can further simulate lifting, sudden braking, and other situations during turns. Combined with the limiting mechanism of this application, this simulator can ensure the safety of the device while simulating changes in flight operations. Attached Figure Description

[0041] Example
[0042] Reference Appendix Figure 1-8 This embodiment provides a flight training simulation device, including a simulation cabin 1. The simulation cabin 1 adopts a conventional cockpit in the prior art, such as the DA40 simulator or a simplified version thereof. Combined with... Figure 1The simulator cabin 1 is typically equipped with an instrument panel 11, a control stick 12, a seat 13, a control panel, and a visual system. A ladder 5 is also provided for easy access to the cabin for trainee pilots. To simulate various flight maneuvers, a six-degree-of-freedom motion platform is generally installed below the simulator cabin 1. This platform works in conjunction with the control stick 12 and the control panel to receive control commands from them, thereby driving the simulator cabin 1 forward, backward, upward, and downward, thus simulating various flight missions. The control panel, visual system, and six-degree-of-freedom motion platform are located within... Figure 1 The above structures are not shown, but they are all conventional structures in the field of flight simulators, and this utility model does not improve upon them.
[0043] The embodiments of this application are improved based on the traditional simulation cabin 1, and also include a moving mechanism 2, a limiting mechanism 3 and a power mechanism 4. The moving mechanism 2 is located below the simulation cabin 1; the limiting mechanism 3 is located on the ground outside the simulation cabin 1 and is used to limit the braking range of the simulation cabin 1; the power mechanism 4 is connected to the moving mechanism 2 and is used to provide rotational power to the simulation cabin 1.
[0044] The moving mechanism 2 includes a hydraulic platform 21 and hydraulic rods 22, which are symmetrically arranged at the four corners of the bottom of the simulation chamber 1. The top end of each hydraulic rod 22 is connected to the bottom surface of the simulation chamber 1, and the bottom end is rotatably mounted in a mounting groove 23. The mounting groove 23 is formed on the hydraulic platform 21 and is located below each of the four hydraulic rods 22. A connecting column 24 is also provided in the mounting groove 23. The bottom end of the hydraulic rod 22 is sleeved on the outside of the connecting column 24, and the hydraulic rod 22 can rotate around the connecting column 24 as the simulation chamber 1 moves.
[0045] The limiting mechanism 3 includes a column 31, a limiting frame 32, and a limiting plate 33. The column 31 is set on the bottom surface and is generally L-shaped. The limiting frame 32 is connected to the bottom of the column 31. The limiting plate 33 is fixedly set on the upper surface of the simulation cabin 1. The limiting frame 32 and the limiting plate 33 are sleeved together. The limiting frame 32 is generally rectangular, and its length is much greater than the width of the limiting plate 33. Its height (vertical direction) is much greater than the installation height of the limiting plate 33 (i.e., the distance between the limiting plate and the simulation cabin). During flight simulation training, if the pilot applies emergency braking via control stick 12, the front of the simulator 1 will tilt downwards and the rear tilt upwards due to inertia. In this case, the limiting plate 33 will slide within the limiting frame 32 during braking. Since the limiting frame 32 and the limiting plate 33 are connected, when the two ends of the limiting frame 32 and the limiting plate 33 come into contact respectively, the braking range of the simulator 1 can be limited to ensure that it is within a safe range and will not cause harm to the trainee, and also ensure that the simulator 1 will not be damaged by accidental collision. In addition, when trainees conduct aircraft lifting simulation training, as the hydraulic rod 22 rises, the simulation cabin 1 moves away from the ground, and the limiting plate 33 rises with the simulation cabin 1 until the limiting plate 33 contacts the top of the limiting frame 32, thereby limiting the lifting height of the simulation cabin 1 and ensuring its maximum lifting range. Conversely, when trainees conduct landing simulation training, as the simulation cabin 1 moves closer to the ground, the limiting plate 33 descends with the simulation cabin 1 until the limiting plate 33 contacts the bottom of the limiting frame 32, thereby limiting the descent position of the simulation cabin 1.
[0046] To simulate turning, this simulation device also includes a power mechanism 4, which comprises a mounting plate 41, a mounting base 42, and a servo motor 43 housed within the mounting base 42. The mounting plate 41 allows the mounting base 42 to be mounted below the ground 6, and the output shaft of the servo motor 43 is connected to the bottom surface of the hydraulic platform 21. The mounting plate 41 has an opening for the output shaft of the servo motor 43 to pass through. In this embodiment, the servo motor 43 can be a DC servo motor. By setting an internal torque limit value for the servo motor, it is ensured that the motor will not exceed its rated torque during operation, thereby limiting its rotation angle and number of revolutions. When the servo motor 43 operates, it drives the simulation chamber 1 to rotate a certain angle (e.g., less than 150°), thus simulating turning.
[0047] The following section uses the flight simulation training of pilot A as an example to introduce the usage process of the flight training simulation device disclosed in this utility model.
[0048] 1. Pilot preparation: Trainees learn the basic operating guidelines of the simulator by reading the user manual or watching training videos, and learn the functions of the various buttons on the simulator.
[0049] 2. Determine the flight mission: Based on training requirements, trainees select a suitable flight mission. Simulator 1 provides different flight missions, including takeoff, landing, rapid descent, and rapid braking.
[0050] 3. In-cabin flight training: Trainees enter the simulator 1 via ladder 5, sit in seat 13, and fasten their seatbelts to begin virtual flight training. They enter the virtual flight environment by operating various buttons on simulator 1. During training, trainees can control the simulator 1's takeoff, landing, braking, etc., using control sticks, foot pedals, and other devices, and can also read various data through the instrument panel and simulated display screen.
[0051] During takeoff simulation training, when the simulator 1 is raised, the hydraulic rod 22 extends until the limiting plate 33 contacts the upper rod of the limiting frame 32. At this point, the simulator 1 has been raised to its maximum height. Conversely, during landing simulation training, when the simulator 1 is lowered, the hydraulic rod 22 shortens until the limiting plate 33 contacts the lower rod of the limiting frame 32. At this point, the simulator 1 has been lowered to its lowest point (i.e., simulating a landing on the ground). In simulated emergency situations, the trainee can use the control lever to brake the simulator 1. Due to inertia, the center of gravity of the simulator 1 will change, such as its tail end tilting up or down. At this time, the simulator 1 is jointly limited by the limiting plate 33 and the limiting frame 32, further restricting the movement range of the simulator 1, thereby ensuring that the simulator 1 operates within a safe range and improving the safety performance of the device.
