Description

Technical Field

[0001] This application belongs to the field of aircraft side control sticks, and specifically relates to a multi-dimensional adjustment device for a side control stick. Background Technology

[0002] In existing technologies, the position of the side control stick in aircraft is usually fixed and non-adjustable. Some models offer limited adjustment functions, but generally only support forward and backward movement, without the ability to adjust in other dimensions. This single-dimensional adjustment capability cannot meet personalized needs, affecting operational comfort and precision. Furthermore, in the early stages of designing new aircraft, extensive evaluation and optimization of the cockpit layout are required. Existing fixed or only forward and backward movable side sticks cannot provide sufficient experimental data to evaluate the impact of different control positions on ergonomics, field of vision, and accessibility in emergency situations, thus limiting the optimization space for cockpit design and potentially creating hidden dangers for subsequent aircraft improvements.

[0003] Therefore, there is an urgent need for a technical solution to overcome or mitigate at least one of the aforementioned defects in the existing technology. Utility Model Content

[0036] The following is in conjunction with the appendix Figures 1 to 4 This application will be described in further detail.

[0037] This application provides a side control stick multi-dimensional adjustment device, such as Figure 1 As shown, it includes: a lifting mechanism 1, a left and right moving mechanism 2, a front and rear moving mechanism 3, and a side control stick base 4.

[0038] like Figure 2-4 As shown, the lifting mechanism 1 includes a lifting base 11, four support arms 12, and a screw 13. A first guide rail is provided on the lifting base 11, and two double-eared connectors are also provided on the lifting base 11, which are used to hinge to the bottom ends of the first and third support arms, respectively. Each support arm 12 includes a first arm, a second arm, a third arm, and a fourth arm. The first and second arms are hinged at their middle sections, and the bottom end of the first arm is hinged to the double-eared connectors on the lifting base 11. The bottom end of the second arm is mounted on the first guide rail via a slider. The third and fourth arms are hinged at their middle sections, and the bottom end of the third arm is hinged to the double-eared connectors on the lifting base 11. The bottom end of the fourth arm is mounted on the first guide rail via a slider. A first connecting block with a through hole is installed between the top ends of the first and third arms. A second connecting block with a threaded hole is installed between the top ends of the second and fourth arms. The screw 13 has a smooth section and a threaded section. After passing through the through hole of the first connecting block, the screw 13 is connected to the threaded hole of the second connecting block.

[0039] In a preferred embodiment of this application, a locking structure is provided between the bottom sliders of the second and fourth arms and the first guide rail, and a first rotating handle 14 is installed at one end of the screw 13.

[0040] By adjusting the first rotary handle 14 to drive the screw 13 to rotate, the distance between the first connecting block and the second connecting block is adjusted, thereby causing the top of the support arm 12 to move up / down, thus adjusting the up / down position of the side control stick. After adjusting the up / down displacement, the slider is locked to the first guide rail, so that the side control stick can be locked in place at any up / down position within the adjustment range.

[0041] like Figure 2-4As shown, the left-right moving mechanism 2 includes a first lead screw base 21, a left baffle 22, a right baffle 23, and a first lead screw 24. The bottom of the first lead screw base 21 is mounted on a first connecting block and a second connecting block. The first lead screw base 21 is fixedly connected to the first connecting block and slidably connected to the second connecting block. A second guide rail is provided on the first lead screw base 21 for slidingly mounting the second lead screw base 31. The left baffle 22 and the right baffle 23 are respectively mounted on the first lead screw base 21, and there is a certain distance between the left baffle 22 and the right baffle 23. The first lead screw 24 is mounted on the left baffle 22 and the right baffle 23 and is used to cooperate with the second lead screw base 31.

[0042] In a preferred embodiment of this application, a second rotary handle 25 is mounted on one end of the first lead screw 24 via a coupling, and a locking structure is provided between the second lead screw base 31 and the second guide rail.

[0043] By adjusting the second rotary handle 25 to rotate the first lead screw 24, the second lead screw base 31 on the first lead screw 24 can slide along the second guide rail in the left-right direction, thereby adjusting the left / right position of the side control stick. After adjusting the left / right displacement, the second lead screw base 31 is locked to the second guide rail, so that the side control stick can be locked in place at any left / right position within the adjustment range.

[0044] like Figure 2-4 As shown, the front-to-back moving mechanism 3 has a similar structure to the left-to-right moving mechanism 2. The front-to-back moving mechanism 3 includes a second lead screw base 31, a front baffle 32, a rear baffle 33, and a second lead screw 34. The second lead screw base 31 is mounted on a second guide rail and is connected to the first lead screw 24. A third guide rail is provided on the second lead screw base 31. The front baffle 32 and the rear baffle 33 are respectively mounted on the second lead screw base 31, and there is a certain distance between the front baffle 32 and the rear baffle 33. The second lead screw 34 is mounted on the front baffle 32 and the rear baffle 33. The side control stick base 4 is mounted on the third guide rail and is connected to the second lead screw 34. A side control stick is mounted on the side control stick base 4.

[0045] In a preferred embodiment of this application, a third rotary handle 35 is mounted on one end of the second lead screw 34 via a coupling, and a locking structure is provided between the side control stick base 4 and the third guide rail.

[0046] By adjusting the third rotary handle 35 to rotate the second lead screw 34, the side control stick base 4 on the second lead screw 34 can slide along the third guide rail in the front-to-back direction, thereby adjusting the front / back position of the side control stick. After adjusting the front / back displacement, the side control stick base 4 is locked to the third guide rail, so that the side control stick can be locked in place at any front / back position within the adjustment range.

[0047] The side control stick multi-dimensional adjustment device of this application has a simple overall motion structure and size, and high reliability. This device can be adjusted a certain distance in three dimensions: forward / backward, left / right, and up / down. After the side control stick is adjusted, it can be fixed in place by a locking structure. The three moving mechanisms of this device ensure that the side control stick can be adjusted within a certain range from three degrees of freedom, thereby realizing multi-dimensional adjustment of the side control stick and meeting the needs of early-stage design evaluation and optimization as well as the pilot's usage requirements.

[0048] The side control stick multi-dimensional adjustment device of this application, compared with the traditional side control stick, adds the adjustment capabilities of left and right and up and down. Moreover, the motion mechanism is simple and reliable, and the operation is simple and easy to understand. It can ensure the side control stick adjustment needs of different pilots, greatly reducing the poor pilot comfort caused by individual differences and the fatigue and muscle soreness caused by long-term flight. It realizes an integrated and comprehensive design, and has the characteristics of high economy, convenience and ease of use. It is suitable for use in the side control stick inside the aircraft cockpit system and has great application value.
