Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aircraft pedal assemblies, in particular to a co-pilot rudder pedal assembly. Background Art
[0002] In the aviation field, the aircraft's control system is a key part of ensuring flight safety. With the continuous development of flight technology, the control methods of aircraft are also constantly evolving. Traditional flight control mainly relies on the pilot to manually operate various mechanical components, such as rudders and elevators, to achieve control of the aircraft. However, with the increasing complexity of modern aircraft, the requirements for the accuracy and response speed of the control system are also getting higher and higher.
[0003] To meet these requirements, modern aircraft generally use fly-by-wire flight control systems, which transmit the pilot's instructions through electrical signals to achieve precise control of the aircraft. In this system, the pilot inputs instructions into the flight computer by operating pedals, side sticks and other control components, and the flight computer then controls the various actuators of the aircraft through electrical signals.
[0004] As an important component of the fly-by-wire flight control system, the design and performance of the aircraft co-pilot pedal assembly are directly related to the accuracy and comfort of flight control. Traditional co-pilot pedal assemblies usually use mechanical or hydraulic connections, which have problems such as slow response speed, low accuracy, and complex maintenance. Currently, common pedals often use electrical connections or force feedback mechanisms for operation.
[0005] However, since the pedals are supported on corresponding shafts, one end of the pedals is rotatably connected to the shafts, and the other end is connected to the corresponding external drive components. At this time, ensuring stable rotation between the pedals and the shafts is essential. However, in actual use, since the soles of shoes directly contact the pedals, impurities on the soles of the shoes can easily enter the rotating part between the pedals and the shafts, affecting the stable transmission of the pedals. This type of pedal and shaft rotating part lacks a component that can block impurities, which is not conducive to the effective impurity blocking effect. In view of this, we propose a co-pilot rudder pedal assembly. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] See also Figure 1-Figure 4 The present invention provides a technical solution: a co-pilot rudder pedal assembly, comprising a pedal body 1 and a transmission member hinge seat 13 provided on the pedal body 1, the transmission member hinge seat 13 being connected to a transmission member on an aircraft, a long shaft 2 being provided on the pedal body 1, a shaft hole 10 being provided in the pedal body 1, both ends of which are connected to the outside world, two left and right symmetrical bearings 12 being provided in the shaft hole 10, the long shaft 2 passing through the inner ring of the bearing 12, the inner and outer rings of the bearing 12 being fixedly mounted on the long shaft 2 and the shaft hole 10 respectively, so that the bearing 12 is not likely to slide left and right;
[0028] Specifically, inner rings 11 concentrically arranged with the shaft hole 10 are fixedly installed on the left and right side surfaces of the pedal body 1. The inner ring 11 is sleeved on the long shaft 2 and rotatably connected to the long shaft 2. Two symmetrical outer rings 21 are fixedly installed on the long shaft 2. The outer rings 21 are sleeved on the corresponding inner rings 11 and rotatably connected to the inner rings 11. The inner rings 11 and the outer rings 21 are arranged to prevent impurities from entering the bearing 12 and the shaft hole 10. The distance between the inner ring 11 and the long shaft 2, and the distance between the outer ring 21 and the inner ring 11 are less than 0.1 mm, which are used to prevent impurities from entering.
[0029] In this embodiment, two groups of symmetrical air outlet holes 20 are provided on the long axis 2. The air outlet holes 20 are located on the inner side of the outer ring 21. The end of the long axis 2 is provided with an air source 3 for ventilating toward the air outlet holes 20, so that the air outlet holes 20 are blown from the inside to the outside, so that even if impurities enter between the inner ring 11 and the outer ring 21, they can be blown out smoothly.
[0030] Specifically, one end of the long axis 2 is sealed, and the other end of the long axis 2 is connected to the outside world. The end of the long axis 2 connected to the outside world is fixedly installed with an end threaded tube 22, and the air outlet 20 is connected to the end threaded tube 22. The air outlet end of the air source 3 is fixedly installed with a hose 31, and the end of the hose 31 is fixedly installed with a hard tube 32. The hard tube 32 and the end threaded tube 22 are plugged together. A tightening ring 33 is fixedly installed on the hard tube 32, and a knob 35 is slidably connected to the hard tube 32. The knob 35 is threadedly connected to the end threaded tube 22 to facilitate stable connection operation.
[0031] Furthermore, the rear arm of the knob 35 rests on the side of the tightening ring 33, the outer diameter of the tightening ring 33 is smaller than the inner diameter of the knob 35, and a sealing ring 34 is sleeved on the hard tube 32. The tightening ring 33 presses the sealing ring 34 against the front side of the end threaded tube 22 to achieve a sealing and tightening operation.
[0032] It is worth noting that the number of each group of air outlet holes 20 is between 10 and 20, and the vertical distance between two adjacent air outlet holes 20 is less than 5 mm, which is conducive to normal air outlet and blowing operation.
[0033] When the co-pilot rudder pedal assembly of the present invention is in use, since the inner ring 11 is sleeved on the long axis 2, and the outer ring 21 is sleeved on the inner ring 11, the distance between the inner ring 11 and the long axis 2, and the distance between the outer ring 21 and the inner ring 11 are small, which can block the entry of impurities. In addition, after the gas source 3 supplies gas, the gas enters the long axis 2 along the hose 31, the hard tube 32 and the end threaded tube 22, and the gas is blown out from the air outlet 20, which can blow out the impurities entering between the outer ring 21 and the inner ring 11, and avoid the outer ring 21 and the inner ring 11 being blocked by impurities.

The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
