DETAILED DESCRIPTION

[0016] The present invention will be further described in detail below through specific examples. The following examples are only illustrative and not restrictive, and the scope of protection of the present invention cannot be limited thereto.

[0017] A lifting device for a flight simulator, the innovation of which lies in: comprising a simulation chamber 1, a simulator 2, a first slide rail 6, a second slide rail 7 and a driving fan 4; first slide rails are horizontally installed at both left and right ends of the lower part of the simulation chamber through a first connecting rod 5; second slide rails are inclined upward above each first slide rail; the simulator slides on the first slide rail through a first slider 11 arranged thereon and slides on the second slide rail through a second slider 14 arranged thereon; driving fans are installed on the front and rear end walls of the simulation chamber through a first fixed plate 3; an air inlet duct 18 connected to the outside of the simulation chamber is installed at the air inlet of the driving fan; and an air outlet duct 17 is installed at the air outlet of the driving fan.

[0018] The simulation chamber consists of a rectangular chamber, observation windows 19, glass panels 20, exhaust ports 15, and dust filters 16. Observation windows are symmetrically located on the front and rear walls of the rectangular chamber, each inlaid with a glass panel. Exhaust ports are symmetrically located on the left and right sides of the upper portion of the rectangular chamber, each equipped with a dust filter to prevent dust from entering. The observation windows facilitate observation of the simulation process.

[0019] The simulator is composed of a connecting plate 10, a first slider, a roller 12, a second fixed plate 9, a second slider, and an air duct 8. Second fixed blocks are symmetrically arranged on the left and right end walls of the air duct. A horizontally arranged connecting plate is installed at the lower end of each second fixed block. A first slider is installed at the front and rear ends of each connecting plate. A slide groove compatible with the first slide rail is provided on the lower end surface of the first slider. The roller is installed below the first slider. A second slider is provided on the side of each second fixed block through a horizontally arranged second connecting rod 13. The second slider slides on the second slide rail through a slide hole provided thereon. The combination of the first slide rail and the first slider mainly serves to limit the simulator, preventing the simulator from shifting left or right.

[0020] The air duct is a triangular structure with one end open. The upper and lower inner walls of the triangular structure are both curved downward, forming a curved angle at the bottom of the duct. The upper and lower outer walls of the triangular structure are both curved outward, intersecting at the top to form a sharp angle. The curved top and bottom of the simulator reduce wind resistance and enhance wind gathering and lift.

[0021] The driving fan can be a jet fan, and there are two groups of driving fans symmetrically arranged. When simulating ascent, the driving fan located at the opening of the air duct works, and the wind blows into the simulator from the opening of the air duct to make the simulator rise. When simulating descent, the second slider on the simulator is brought into contact with the second slide rail, starting the driving fans on both sides, and controlling the output power of the two groups of driving fans through an external controller, thereby realizing a slow descent of the simulator.

[0022] Working principle: Place the simulator into the simulation chamber, make the roller on the simulator contact the bottom of the simulation chamber, and set the first slider on the first slide rail;

[0023] Start the driving fan on the rear side, and the simulator moves forward horizontally under the action of wind. When the second slider contacts the second slide rail, the simulator starts to rise;

[0024] The simulator's travel direction is changed so that the second slider on the simulator contacts the second slide rail, the drive fans on both sides are started, and the output power of the two sets of drive fans is controlled by an external controller, thereby achieving deceleration and descent of the simulator;

[0025] When simulating, the contact friction between the simulator and other structures should be taken into account.

[0026] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
