[0023] This application provides a handle control mechanism, which is described below with reference to... Figures 1 to 6 Provide a detailed description.

[0024] In one embodiment, refer to Figure 1 and Figure 2 The handle control mechanism includes a shaft 12, a steel cable assembly, a pointer 24 assembly, a control handwheel 1, a first bracket 10, and a second bracket 4. The shaft 12 is supported in the shaft 12 bearing hole of the first bracket 10. The control handwheel 11 is sleeved on the shaft 12 and away from the first bracket 10. The pointer 24 assembly includes a spiral disc 2, a pointer 24, a nameplate 21, and a support 22. The spiral disc 2 is fixedly connected to the shaft 12 and connected to the back of the control handwheel 1. One end of the pointer 24 is movably connected to the spiral disc 2, and the other end of the pointer 24 is fixed in a bushing on the side arm of the engine control panel. The nameplate 21 is fixed on the support 22, and the support 22 is fixed on the second bracket 4. The second bracket 4 is sleeved on the shaft 12. The steel cable assembly is fixedly connected to the shaft 12 and is located between the first bracket 10 and the second bracket 4. Rotating the control handwheel 1 drives the shaft 12 and the steel cable assembly to rotate together via the spiral disc 2.

[0025] In this embodiment, the control handwheel 1 is mounted on the shaft 12. By selecting the control handwheel 1, the steel cable assembly is rotated. One end of the pointer 24 moves radially on the spiral disk 2 as the disk rotates, causing it to shift relative to the label 21, thereby indicating the scale and determining the direction and angle of the adjustment plate deflection. This allows for the deflection of the adjustment plate, reducing the driver's workload on the control surfaces.

[0026] Furthermore, refer to Figure 4 and Figure 5 The back of the spiral disk 2 has a spiral groove, and one end of the pointer 24 has a first shaft that slides within the spiral groove. As the spiral disk 2 rotates, the first shaft of the pointer 24 moves radially within the spiral groove, causing displacement relative to the mark 21, thus indicating the scale. This design makes the movement of the pointer 24 smoother and more precise, accurately reflecting the deflection of the adjustment plate.

[0027] Furthermore, refer to Figure 3 The front of the spiral disk 2 has multiple bosses, and the back of the operating handwheel 1 has multiple grooves. The bosses and grooves are connected by a mating fit. Through the mating fit of the bosses and grooves, the rotation of the operating handwheel 1 drives the rotation of the spiral disk 2, which in turn drives the shaft 12 to rotate.

[0028] Furthermore, in order to protect the sign 21 from contamination or damage, the pointer 24 assembly also includes an acrylic glass 18 and a third bracket 20. The third bracket 20 is fixed on the support 22, and the acrylic glass 18 is mounted on the third bracket 20. The acrylic glass 18 covers the sign 21, and the scale on the sign 21 can be seen through the acrylic glass 18.

[0029] Furthermore, the cable assembly includes a cable drum 7, a second bushing 5, and a third bushing 9. The cable drum 7 is connected to the shaft 12 by bolts. The second bushing 5 and the third bushing 9 are respectively installed at the front and rear ends of the cable drum 7. A steel cable is wound around the cable drum 7. The steel cable includes a first steel cable and a second steel cable, which are connected to the elevator adjustment plate control line. Specifically, refer to... Figure 6 The first and second steel cables correspond to the lower and upper deflection cables, respectively, and are guided by cable guide wheels. Cable guide plates are fitted onto the lower and upper deflection cables. The lower deflection cable bypasses the drum 33 to become the upper deflection cable, and the drum drives the elevator trim plate to deflect. When the control lever 28 rotates clockwise, the lower deflection cable is under tension, causing the drum 33 to rotate. This, in turn, causes the drum 33 to drive the elevator trim plate 34 to deflect upwards, achieving the aircraft trim function.

[0030] In one embodiment, the spiral disk 2 is fixedly connected to the shaft 12 via a spline.

[0031] In one embodiment, the handle control mechanism further includes a top cover 17, one end of which is fixed to a first bracket 10 and the other end of which is fixed to a second bracket 4, with the cable assembly located inside the top cover 17.

[0032] In one embodiment, the front end of the center of the operating handwheel 1 is provided with a front cover 26 and a nut 25, which limit the operating handwheel 1 on the shaft 12.

[0033] In one embodiment, refer to Figure 5 The other end of the pointer 24 is provided with a second shaft, through which the pointer 24 is supported in a bushing on the side arm of the engine control panel.

[0034] In one embodiment, refer to Figure 3 There are four bosses and four grooves, which are evenly distributed on the circumferential surface.

[0035] In practical implementation, the steel cable assembly is connected to the shaft 12 via bolts or other connectors, and the various components are connected to each other via bolts, screws, or other connectors, including the first bushing 3, small shaft 11, first bolt 13, second bolt 14, first screw 15, second screw 16, third screw 19, and third bolt 23. This embodiment is merely an example and is not limited to the types and quantities of connectors listed in this embodiment.

[0036] The working principle of the handle control mechanism in this application is as follows: When the pilot turns the control handwheel 1, the control handwheel 1 drives the spiral disk 2 to rotate. Since the spiral disk 2 is fixedly connected to the shaft 12, the shaft 12 also rotates accordingly. The rotation of the shaft 12 further drives the cable assembly to rotate. The cables in the cable assembly are guided by guide wheels and guide plates, and finally connected to the elevator trim control lines. When the cable assembly rotates, it pulls or releases the corresponding cables, thereby driving the drum 33 to rotate. The drum 33 then drives the elevator trim to deflect. At the same time, the rotation of the spiral disk 2 causes the first axis of the pointer 24 to move radially within the spiral groove. The pointer 24 is displaced relative to the label 21, thereby indicating the direction and angle of the trim deflection. The pilot can precisely control the deflection of the trim according to the indication of the pointer 24 to achieve the aircraft trim function, reduce the control burden, and improve flight safety.

[0037] The embodiments provided by this invention achieve efficient and precise control of aircraft control levers through the ingenious design and combination of the various components of the control lever mechanism. This control lever mechanism is compact in structure and easy to operate, effectively reducing the pilot's workload when manipulating control surfaces and improving aircraft handling performance and flight safety. In practical applications, the size and material of the control lever mechanism can be appropriately adjusted and optimized according to the specific needs of different aircraft to better meet actual usage requirements. Furthermore, the design concept and method of this control lever mechanism can also provide reference and guidance for designs in other related fields.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
