DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Combine the following Figures 1 to 6 The invention describes a hovering rescue test device for a helicopter simulation cockpit.

[0021] In one embodiment, a hovering rescue test device for a helicopter simulation cockpit includes a base plate 110, two docking platforms 120, two fixing frames 130, a flight simulation cockpit 200, two sliding members 400, two lifting members 500, and two retractable connecting members 600; the two docking platforms 120 are respectively fixed at two ends of the upper surface of the base plate 110, and a test space 111 is formed between the two docking platforms 120 and the base plate 110; the two fixing frames 130 are symmetrically arranged, and the two ends of the fixing frames 130 are respectively connected to the base plate 110. The two ends of the upper surface of the two docking platforms 120 are fixedly connected, and an installation space 131 is set in the fixed frame 130; the flight simulation cockpit 200 is docked on the docking platform 120; the two sliding members 400 are slidably installed in the two installation spaces 131 respectively; the two lifting members 500 are respectively installed on the two sliding members 400 in the vertical direction; one end of the two retractable connecting members 600 is fixed to the two side ends of the flight simulation cockpit 200, and the other ends of the two retractable connecting members 600 are respectively movably inserted in the two lifting members 500.

[0022] Specifically, during training, the flight simulation cockpit 200 first docks on a docking station 120 and then flies to another docking station 120. During the flight, the flight simulation cockpit 200 is connected to the lifting member 500 through two retractable connectors 600 and can be lifted and lowered along the lifting member 500. The sliding member 400 is used to control the flight direction of the flight simulation cockpit 200. During the flight, the flight state of the flight simulation cockpit 200 is judged according to the changing trajectories of the two retractable connectors 600, so that when the flight simulation cockpit 200 is above the test space 111, various actions of the flight simulation cockpit 200 are detected, and the test process and results are determined according to the detection results.

[0023] In the above-mentioned hovering and rescue test device for the helicopter simulation cockpit, the flight simulation cockpit 200 first docks on a docking platform 120, then flies to another docking platform 120, and is connected to the lifting member 500 through two retractable connectors 600 during the flight, and can be lifted and lowered along the lifting member 500, and the sliding member 400 is used to control the flight forward direction of the flight simulation cockpit 200, and the flight state of the flight simulation cockpit 200 is judged according to the change trajectory of the two retractable connectors 600 during the flight, so that when the flight simulation cockpit 200 is above the test space 111, the various actions of the flight simulation cockpit 200 are detected, and the test process and results are determined according to the detection results. The hovering and rescue test device has high training convenience and relatively low training difficulty, and the training results are clear and traceable.

[0024] In one embodiment, a first flow guide hole 121 and a plurality of second flow guide holes 122 are provided on the docking platform 120, wherein the end of the first flow guide hole 121 directly faces the test space 111, and the plurality of second flow guide holes 122 are arranged around the first flow guide hole 121, and one end of the second flow guide hole 122 is inclined toward the central axis direction of the first flow guide hole 121.

[0025] Specifically, the first air guide hole 121 and the second air guide hole 122 extend through one end outside the docking platform 120 for connecting an air supply device, the end of the first air guide hole 121 facing the test space 111 is used to blow wind in a straight direction into the test space 111, and the end of the second air guide hole 122 facing the test space 111 is used to blow wind in an inclined direction into the test space 111. Liquid can be injected into the test space 111, and wind in various directions can be simulated through the first air guide hole 121 and the second air guide hole 122 to make the training scene more similar to the actual rescue scene.

[0026] In one embodiment, two first guide rods 300 are transversely fixed in the installation space 131, and two installation holes 450 are provided on the sliding member 400. The two first guide rods 300 are respectively inserted into the two installation holes 450. The two sliding members 400 have installation cavities 410 on opposite sides. The bottom surface of the installation cavity 410 is set as an arc surface 420, and a plurality of detection plates 700 are laid on the arc surface 420.

[0027] Specifically, when the flight simulation cockpit 200 is conducting training, the sliding member 400 is driven to move in the direction of the first guide rod 300. According to the flight status of the flight simulation cockpit 200 and the progress of the hovering and rescue training, the end of the retractable connecting member 600 will abut against one or more detection plates 700 on the curved surface 420. The actions performed by the flight simulation cockpit 200 during the hovering and rescue training can be judged based on the detection results of the two detection plates 700. Combined with the actions required by the training, a preliminary judgment can be made on the hovering and rescue training.

[0028] At the same time, since the two curved surfaces 420 are arranged relative to each other, when an error occurs in the operation of the flight simulation cockpit 200 and the flight is too high or too low, due to the contact between the retractable connecting piece 600 and the curved surface 420, the flight simulation cockpit 200 is more difficult to raise or lower the further away from the middle of the curved surface 420, thereby avoiding possible accidents during training.

[0029] In one embodiment, two installation grooves 430 are respectively opened on both sides of the installation cavity 410, and second guide rods 440 are vertically installed in the installation grooves 430. The two ends of the lifting member 500 are respectively movably installed on the two second guide rods 440, and the telescopic connecting member 600 is movably inserted into the lifting member 500, and the end of the telescopic connecting member 600 is abutted against the detection plate 700.

[0030] Specifically, the lifting member 500 includes a spherical shell 510 and two clamping blocks 520; two through holes 511 are respectively opened on the two side surfaces of the spherical shell 510 along its diameter direction, and the other two side surfaces of the spherical shell 510 are respectively connected to the two clamping blocks 520, and the two clamping blocks 520 are respectively movably sleeved on the two second guide rods 440.

[0031] In one embodiment, the retractable connecting member 600 includes a fixed tube 610, a spherical shell 620, an abutment rod 630 and an elastic member 640; one end of the fixed tube 610 is connected to the side end of the flight simulation cabin 200, and the other end is inserted into the spherical shell 620, the spherical shell 620 is rotatably installed in the spherical shell 510, one end of the abutment rod 630 is inserted into one end of the fixed tube 610 facing the curved surface 420, and the elastic member 640 is arranged in the fixed tube 610, and is used to push the other end of the abutment rod 630 toward the curved surface 420.

[0032] Specifically, the spherical shell 620 can rotate arbitrarily in the spherical shell 510, and the fixed tube 610 movably passes through the spherical shell 620. When the flight simulation cockpit 200 performs hovering rescue training, the fixed tube 610 can be tilted in various directions according to the training action, so that the end of the abutment rod 630 abuts against different detection plates 700.

[0033] There are a plurality of detection plates 700 linearly spaced apart along the bending direction of the arc surface 420 , and a plurality of detection plates 700 are also linearly spaced apart along the horizontal direction.

[0034] In one embodiment, two limiting rings 650 are sleeved on the fixing tube 610 , and the two limiting rings 650 are respectively located at the sides of the spherical shell 510 that are away from the two through openings 511 .

[0035] Specifically, in order to avoid large position deviation during training, two limit rings 650 are provided on the fixed tube 610 to limit the flight and training basic path range of the flight simulation cockpit 200, thereby providing trainers with more obvious operation targets and improving training efficiency.

[0036] Preferably, a detection element may be provided on the limiting ring 650 for detecting whether contact occurs with the spherical shell 510 or the spherical sleeve 620 .

[0037] In one embodiment, a spiral guide rail 310 is installed on the first guide rod 300, and a snap-in hole 460 is opened on the side of the mounting hole 450. The spiral guide rail 310 is snap-into the snap-in hole 460. The first guide rod 300 passes through one end of the fixed frame 130 and is installed with a limiting wheel 800. A limiting seat 900 is also installed on the side end of the fixed frame 130. The side of the limiting seat 900 abuts against the side of the limiting wheel 800 to increase the rotation resistance of the limiting wheel 800.

[0038] Specifically, the limiting wheel 800 includes a first rotating rod 810 and a rotating block 820; the first rotating rod 810 is fixedly connected to the first guide rod 300, the rotating block 820 is sleeved on the first rotating rod 810, and a plurality of grooves 821 are provided on the side of the rotating block 820 in a circular array; the limiting seat 900 includes a second rotating rod 910 and a limiting block 920; the second rotating rod 910 is fixed to the side of the fixed frame 130, the limiting block 920 is rotatably mounted on the second rotating rod 910, and a rubber pad 930 is provided on the side of the limiting block 920, and the rubber pad 930 abuts against the side of the rotating block 820. The surface of the rubber pad 930 is set to be arc-shaped, and when the middle position of the rubber pad 930 abuts against the rotating block 820, the abutting force between the rubber pad 930 and the rotating block 820 is minimal.

[0039] When the sliding member 400 moves along the first guide rail, the first guide rod 300 rotates under the influence of the spiral guide rail 310, and the side of the limit block 920 abuts against the limit wheel 800 to simulate the wind resistance of the helicopter in the actual hovering rescue environment. Since the surface of the rubber pad 930 is arranged in an arc shape, and the abutment force between the two ends of the arc surface and the rotating block 820 will be greater after the arc surface rotates around the second rotating rod 910, the flight wind resistance of the flight simulation cockpit 200 can be simulated and set by changing the rotation angle of the second rotating rod 910.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
