[0002] A simulation aircraft is the main equipment for simulating the training of a real aircraft. A handle identical to that in the real aircraft is provided in the simulation aircraft. After the handle moves, it needs to automatically return to its original position. The existing automatic return of the handle is mainly realized by a spring or a worm and worm gear. Although the spring method has a fast response, the return spring force decreases after long-term use, resulting in the inability to return to the center during reset. The return mechanism using the worm and worm gear structure has a large volume and requires cooling of the gears, resulting in a high cost.
[0003] The existing handle return structure may cause elastic failure, resulting in a worse centering effect and a complex structure. Content of the Utility Model

Detailed implementation manners
[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0031] Referring to Figures 1 - 7 as shown, in the embodiment of the present utility model, an automatic - return handle for a simulated aircraft is proposed, which includes a base 1. A partition plate 2 is arranged inside the base 1. The partition plate 2 divides the interior of the base 1 into a rotation cavity and a return cavity. A rod assembly 3 is installed in the rotation cavity. The rod assembly 3 includes a swing rod 31. One end of the swing rod 31 extends into the return cavity and is locked with a nut 4. The other end of the swing rod 31 extends out of the base 1 and is connected with a handle 5. A positioning pin 14 for connecting the handle 5 is arranged on the swing rod 31, which facilitates the replacement and installation of the handle 5 by using the positioning pin 14; the swing rod 31 is limited and connected to the partition plate 2 through the nut 4, so that when the swing rod 31 moves, the rod assembly 3 moves in the rotation cavity without detaching from the base 1.
[0032] The reset action mainly lies in resetting the swing rod 31 to the center relative to the base 1, that is, realizing the position reset of the handle 5 relative to the base 1. Specifically, a first damper 6 and a second damper 7 for connecting the rod assembly 3 are installed on the base 1. The axis of the first damper 6 is perpendicular to the axis of the second damper 7. When the swing rod 31 drives the entire rod assembly 3 to move in the base 1, the first damper 6 and the second damper 7 can generate damping forces, so that there is a feedback force during the operation process. At the same time, the damping force acts in the reverse direction to have a tendency to push the swing rod 31 back to the center. At the same time, a reed seat 8 and two layers of reset reeds 9 fixed to the reed seat 8 are installed in the return cavity. The reset reeds 9 are sleeved on the swing rod 31. The two layers of reset reeds 9 are fixed in the return cavity through the reed seat 8. The swing rod 31 passes through the two layers of reset reeds 9. When an angular swing occurs, the reset reeds 9 apply an elastic force for centering reset to the swing rod 31. Thus, under the combined action of the two layers of reset reeds 9, the first damper 6, and the second damper 7, it can be ensured that after the handle 5 is released, the swing rod 31 can drive the handle 5 to achieve centering reset. The combined action of the two forces improves the reliability and avoids the risk of the reset acting force failing.
[0033] In order to improve the elastic deformation ability of the reset reed and have a good elastic effect for centering reset, specifically, the reset reed 9 includes a sheet body 91 and a plurality of connection holes 92 evenly distributed along its circumferential direction. A plurality of triangular holes 93 evenly distributed along the circumferential direction and communicating at the center of the sheet body 91 are opened on the sheet body 91. The reset reed 9 is fixed through the connection holes 92, and a plurality of triangular holes 93 communicating at the center are opened on the sheet body 91, so that there is an elastic part in the middle that can abut against the swing rod 31. The elastic parts are evenly distributed axially and abut against the swing rod 31, prompting the swing rod 31 to automatically return to the center for reset.
[0034] At the same time, in order to ensure the elasticity and deformation recovery performance of the entire reset reed 9, the material of the reset reed 9 is 3J21 elastic alloy.
[0035] Among them, the first damper 6 and the second damper 7 adopt labyrinth silicone oil dampers, which are a type with better damping effects in the prior art and can be directly applied. The first damper 6 and the second damper 7 can achieve rotational damping.
[0036] Specifically, the rod assembly 3 includes a first rotating arm 32 and a second rotating arm 33 rotatably mounted on the base 1. The rotation axis of the first rotating arm 32 is perpendicular to the rotation axis of the second rotating arm 33. An arc-shaped portion 34 sleeving on the first rotating arm 32 is provided on the second rotating arm 33. A sliding groove 35 is formed on the arc-shaped portion 34. The swing rod 31 is mounted on the first rotating arm 32. After the first rotating arm 32 and the second rotating arm 33 are vertically rotatably mounted on the base 1, the swing operation of the swing rod 31 at any angle can be realized. The swing angle of the swing rod 31 is adjusted by the rotation of the first rotating arm 32 and the change of the rotation angle of the second rotating arm 33, that is, the operation position of the handle 5 is adjusted.
[0037] Wherein, one end of the first rotating arm 32 is connected to the first damper 6, and the other end of the first rotating arm 32 is connected with a first adjusting member 12. The first adjusting member 12 is mounted on the base 1. The first adjusting member 12 is used to adjust the damping force of the first rotating arm 32 pushing the first damper 6. The first damper 6 generates rotational damping on the first rotating arm 32, and the rotational flexibility of the first rotating arm 32 and the connection state with the first damper 6 are adjusted through the first adjusting member 12.
[0038] Similarly, one end of the second rotating arm 33 is connected to the second damper 7, and the other end of the rotating arm is connected with a second adjusting member 13. The second adjusting member 13 is mounted on the base 1. The second adjusting member 13 is used to adjust the damping force of the second rotating arm 33 pushing the second damper 7. The second damper 7 generates rotational damping on the second rotating arm 33, and the rotational flexibility of the second rotating arm 33 and the connection state with the second damper 7 are adjusted through the second adjusting member 13.
[0039] Wherein, the first adjusting member 12 and the second adjusting member 13 can adopt a rotating mechanism, such as a gear set or a knob, etc.
[0040] In order to achieve dust-proof inside, a dust-proof cover 10 is sleeved on the swing rod 31. One end of the dust-proof cover 10 is connected to the handle 5, and the other end of the dust-proof cover 10 is connected to the base 1. The dust-proof cover 10 forms a protection between the base 1 and the handle 5. At the same time, the dust-proof cover 10 has deformability, so as to maintain the protection effect when following the movement of the handle 5.
[0041] At the same time, a base 11 for sealing the return cavity is mounted on the base 1. The base 11 is used to cooperate with the base 1 to install the whole structure into the simulated aircraft.
