Description

Technical Field

[0001] This invention belongs to the field of aircraft EWIS (Electrical Wiring Interconnection System) product design technology, specifically a cable movement and stroke scaling system. Background Technology

[0002] Optical and electrical components in moving parts of an aircraft need to maintain optical and electrical signal connections with other parts to ensure safe operation. In specific areas, such as flaps, landing gear, folding wings, and tiltrotors, simple cables cannot meet the motion requirements; therefore, products with corresponding functions are needed to achieve both motion and optical / electrical connectivity. Existing products typically achieve this through helicals or motion guides; however, these products cannot meet the motion requirements of large angles, deflection axes, and long strokes. Therefore, a new motion system needs to be invented to meet these motion requirements. Summary of the Invention

[0003] To address the limitations of existing products in meeting the demands for large-angle, deflection-axis, and long-stroke motion, this invention aims to provide a cable motion and stroke scaling system. This system enables large-angle, deflection-axis, and long-stroke motion, and can integrate various cables such as low-frequency conductors, coaxial cables, and optical fibers for motion. It features the ability to accommodate a large number of cables, shorten or amplify the motion stroke, and deviate from the main motion area, while maintaining continuous and uninterrupted signal transmission.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] This invention includes a support structure, a motion scaling drive, and a motion cable. The support structure includes side panel assembly A, side panel assembly B, a bottom plate, a top support assembly, and a cable bracket. The bottom plate is a fixed component. Side panel assembly A and side panel assembly B are mounted opposite each other on the bottom plate. The top support assembly is fixed to the top of side panel assembly A and side panel assembly B. The cable bracket is fixedly connected to the bottom plate. The motion scaling drive includes a push rod assembly, a transmission scaling assembly, and an isolation transmission component. The transmission scaling assembly includes a transmission rack, a gear transmission assembly, and a toothed worm gear. The transmission rack is slidably mounted on side panel assembly A. One end of the push rod assembly is connected to a moving part on the aircraft, and the other end is connected to the transmission rack. The toothed worm gear is rotatably mounted on... On the top support assembly, the isolation transmission component is threadedly connected to the toothed worm gear, and the transmission rack is connected to the toothed worm gear through a gear transmission assembly. The motion cable section includes multiple bundles of motion cable assemblies, each bundle of which passes through the isolation transmission component. One end of each bundle of motion cable assemblies is fixed to a cable bracket, and the other end of each bundle of motion cable assemblies is connected to a moving part on the aircraft. Under the movement of the moving part, the push rod assembly drives the transmission rack to slide back and forth. The transmission rack converts the sliding motion into the rotational motion of the toothed worm gear through the gear transmission assembly. The lifting and lowering of the isolation transmission component is achieved through the helical pair between the toothed worm gear and the isolation transmission component. During the movement of the moving part, each bundle of motion cable assemblies provides the required movement margin and is limited by the lifting and lowering of the isolation transmission component.

[0068] like Figures 1A-1C and Figure 2 , Figure 6 , Figure 10A , Figure 10B As shown, the motion cable assembly 4 in this embodiment is designed with a three-wire harness to meet the triple redundancy requirements of the aircraft system. The motion cable assembly 4 is existing technology and includes a motion harness 401, a connector 402, and a tail accessory 403.

[0069] like Figures 1A-1C and Figure 2 , Figure 3 , Figure 4 , Figure 9 , Figure 10A , Figure 10B , Figure 11A , Figure 11BAs shown, this embodiment has two toothed worm gears, namely toothed worm gear A11 and toothed worm gear B12. Toothed worm gear A11 and toothed worm gear B12 have the same structure, both having a beveled tooth head, a smooth shaft, and a helical shaft. Toothed worm gear A11 has two smooth shafts, located at the top and bottom respectively, with a helical shaft between the two smooth shafts. The smooth shaft at the top of toothed worm gear A11 is installed in a bushing G702 of the top bracket 701, and the smooth shaft at the bottom of toothed worm gear A11 is installed in a bushing I100 on the side wall long support 1001.

The conical teeth of both toothed worm gears A11 and B12 are located below the bottom smooth rod. The thread of the helical rod of toothed worm gear A11 is counterclockwise, while the thread of the helical rod of toothed worm gear B12 is clockwise. The conical teeth of both toothed worm gears A11 and B12 have the same number of teeth, achieving synchronous movement.

[0070] like Figures 1A-1C and Figure 2 , Figure 3 , Figure 4 , Figure 12 , Figure 13 , Figure 15A , Figure 15B , Figure 16A , Figure 16B , Figure 17As shown, the gear transmission assembly of this embodiment includes a compound gear 15, a transmission rod 18, and a bevel gear 16. One end of the transmission rod 18 is installed in a bushing A102 on the side wall plate A101, and the other end of the transmission rod 18 is installed in a bushing C202 on the side wall plate B201, thereby enabling the transmission rod 18 to rotate relative to the side wall plates A101 and B201. The compound gear 15 is connected to one end of the transmission rod 18 through a flat key pin A13, and the bevel gear 16 is connected to the other end of the transmission rod 18 through a flat key pin B14. Both the compound gear 15 and the bevel gear 16 are linked with the transmission rod 18 and lock the axial movement trend, thereby realizing the synchronous movement of the compound gear 15 and the bevel gear 16 and converting the linear motion of the transmission spur rack 103 into rotational motion. In this embodiment, both ends of the transmission rod 18 are provided with keyways C1801 to accommodate the flat key pins A13 and B14. Stepped sections are provided at both ends of the transmission rod 18 to ensure that the compound gear 15 and bevel gear 16 are maintained in the correct positions. One side of the compound gear 15 in this embodiment has a spur tooth 1501 that meshes with the transmission rack 103, and the other side has a bevel tooth 1502 that meshes with the bottom bevel tooth of the toothed worm A11. The bevel teeth cooperate with the toothed worm A11 to change the motion angle and transmit motion. The number of spur teeth 1501 and bevel teeth 1502 is set according to a gear ratio of 1:6, and the number of bevel teeth 1502 and the bevel tooth of the toothed worm A11 is set according to a gear ratio of 3:1. The screw pitch of the toothed worm A11 is 3.5mm. Through the above arrangement, the motion stroke of the isolation transmission component 8 is amplified compared to the push rod assembly 5, thereby obtaining the required motion margin. The compound gear 15 has a keyway A1503, which engages with a flat key pin A13 to lock the transmission rod 18. The bevel gear 16 meshes with the bottom bevel teeth of the worm gear B12, changing the motion angle and transmitting motion. The bevel gear 16 has a keyway B1601, which engages with a flat key pin B14 to lock the transmission rod 18. The number of teeth on the bevel gear 16 is the same as the number of teeth on the other side of the compound gear 15 (the bevel teeth 1502) to maintain synchronous movement.

[0071] The working principle of this invention is as follows:

[0072] like Figure 18As shown, the bottom plate 3 is fixed to the fixed part 25 on the aircraft, and the other end of each bundle of motion cable assemblies 4 is connected to the moving part 24 on the aircraft. When the moving part 24 moves, the push rod assembly 5 drives the transmission rack 103 to slide back and forth under the action of the moving part 24. The transmission rack 103 meshes with the spur teeth 1501 in the compound gear 15, the bevel teeth 1502 in the compound gear 15 mesh with the bevel teeth of the toothed worm A11, and the bevel gear 16 meshes with the bevel teeth of the toothed worm B12, converting the linear motion of the transmission rack 103 into the rotational motion of the toothed worm A11 and the toothed worm B12. The lifting and lowering of the isolation transmission component 8 is achieved through the helical pairs between the toothed worm A11 and the toothed worm B12 and the isolation transmission component 8, respectively.
