[0018] The present invention is further described in detail below by means of specific embodiments in combination with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] See also Figure 1 , the figure shows an aircraft control handle lifting and rotating mechanism with a damping feel.

[0020] The aircraft control handle lifting and rotating mechanism comprises: a mechanism housing 1, a main shaft component 2, a rod component 3, a damping component 4, etc. The control actions of the aircraft control handle lifting and rotating mechanism include: a lifting action and a rotating action.

[0021] The spindle component 2 includes a transverse spindle 21 , a spindle bearing 22 , etc. The transverse spindle 21 and the spindle bearing 22 are axially matched. The spindle bearing 22 is fixed. The transverse spindle 21 can rotate inside the spindle bearing 22 .

[0022] Preferably, the mechanism housing 1 has a bearing accommodating groove. The main shaft bearing 22 is located inside the bearing accommodating groove and is sealed and limited by the bearing retaining ring 23.

[0023] See also Figure 2 The rod component 3 includes a vertical rotating rod 31, a vertical operating rod 32, a rod holding portion 33, a spring fixing frame 34, a limiting movable block 35, a compression spring 36, etc.

[0024] The vertical rotating rod 31 is perpendicular to the transverse main shaft 21 of the main shaft component 2. The lower end of the vertical rotating rod 31 is fixedly connected to the transverse main shaft 21. The vertical rotating rod 31 rotates synchronously with the transverse main shaft 21.

[0025] In one embodiment, the lower end of the vertical rotating rod 31 has a through hole, and the transverse main shaft 21 is axially matched with the through hole of the vertical rotating rod 31 to achieve a fixed connection between the lower end of the vertical rotating rod 31 and the transverse main shaft 21. Preferably, the through hole of the vertical rotating rod 31 is a waist-shaped structure.

[0026] A U-shaped surrounding wall 37 is provided on one axial side surface of the vertical rotating rod 31. The axial side surface and the U-shaped surrounding wall 37 together form a receiving sliding groove with an upward opening and an axial opening.

[0027] The lower end of the vertical operating rod 32 is inside the accommodating chute. The lower end of the vertical operating rod 32 and the accommodating chute form a sliding pair. The lower end of the vertical operating rod 32 can move up and down along the accommodating chute. The upper end of the vertical operating rod 32 has the rod gripping portion 33.

[0028] The spring fixing frame 34 is on the axial side of the vertical rotating rod 31. The spring fixing frame 34 has a fixing frame vertical portion 341 and a fixing frame transverse portion 342. The fixing frame vertical portion 341 and the fixing frame transverse portion 342 form an H-shaped structure or a door-shaped structure. The fixing frame vertical portion 341 covers the side portion of the U-shaped surrounding wall 37, and the two can be fixedly connected by screws. The fixing frame transverse portion 342 covers the lower end portion of the vertical operating rod 32 to limit the lower end portion of the vertical operating rod 32 in the accommodating slot to prevent it from slipping out of the axial opening.

[0029] The limiting movable block 35 is located on the axial side of the vertical rotating rod 31 and below the fixing frame transverse portion 342. The limiting movable block 35 can be fixedly connected to the lower end of the vertical operating rod 32 by screws.

[0030] The compression spring 36 is disposed between the horizontal portion 342 of the fixing frame and the position limiting movable block 35. The compression spring 36 is in a compressed state. The downward force of the compression spring 36 acts on the position limiting movable block 35, so that the position limiting movable block 35 drives the lower end of the vertical operating rod 32 to abut against the bottom edge of the U-shaped surrounding wall 37. An upward force is applied to the vertical operating rod 32, and the vertical operating rod 32 shifts upward along the accommodating slide groove. During the shifting process, the vertical operating rod 32 further compresses the compression spring 36 through the position limiting movable block 35.

The damping component 4 comprises an adjusting nut 41, a compression spring 42, a damping friction plate 43, a damping fixed plate 44, etc. The transverse main shaft 21 passes through the adjusting nut 41, the compression spring 42, the damping friction plate 43, and the damping fixed plate 44 in sequence. Among them, the damping fixed plate 44 is fixed and does not interfere with the rotation of the transverse main shaft 21, while the adjusting nut 41, the compression spring 42, the damping friction plate 43 rotate synchronously with the transverse main shaft 21. The adjusting nut 41 applies a force to the damping friction plate 43 in the direction of the damping fixed plate 44 through the compression spring 42, so that the damping friction plate 43 is against the damping fixed plate 44. The transverse main shaft 21 rotates, the damping friction plate 43 rotates synchronously, and the damping fixed plate 44 is fixed, that is, the damping friction plate 43 and the damping fixed plate 44 generate relative friction to form the rotation damping force.

[0033] The adjusting nut 41 and the transverse main shaft 21 form a thread pair. The adjusting nut 41 is displaced to gradually change the magnitude of the rotation damping force, that is, the magnitude of the rotation damping force is continuously adjustable within a certain range.

[0034] Preferably, the damping friction plate 43 has a through hole. The transverse main shaft 21 is matched with the through hole of the damping friction plate 43. The through hole of the damping friction plate 43 is preferably a waist-shaped structure.

[0035] Preferably, the damping fixing plate 44 has a through hole, and the transverse main shaft 21 and the through hole of the damping fixing plate 44 are idlingly matched to prevent interference between the two.

[0036] Preferably, there is an anti-loosening washer 45 between the adjusting nut 41 and the compression spring 42. The anti-loosening washer 45 is used to prevent the adjusting nut 41 from loosening.

[0037] See also Figure 4 , the aircraft control handle lifting and rotating mechanism may further include: a gear switching plate 5, a gear switching wheel 6, etc. The gear switching plate 5 is fixed. The gear switching plate 5 has a gear switching groove 50. The gear switching wheel 6 is inside the gear switching groove 50. The gear switching wheel 6 is fixedly connected to the vertical joystick 32. The method of using the vertical joystick 32 is as follows: pull the lever holding part 33 upward, and the vertical joystick 32 drives the gear switching wheel 6 to leave the initial slot. At this time, further push and pull the lever holding part 33, and when the gear switching wheel 6 reaches the target slot, release the lever holding part 33, the compression spring 36 resets the vertical joystick 32, and the gear switching wheel 6 automatically enters the target slot.

[0038] Preferably, the gear switching plate 5 can be fixed to the mechanism housing 1 by screws.
