In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0037] Combine the following Figures 1 to 4 The pedal adjustment structure and aircraft pedal system of the present application are described.

[0038] According to the embodiment of the first aspect of the present application, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the pedal adjustment structure includes:

[0039] Bracket 1;

[0040] A left brake assembly 2 and a right brake assembly 3 are symmetrically arranged about the bracket 1. The right brake assembly 3 includes a right brake cylinder 31, a right brake pedal 32 and a right connecting member 33. The first end of the right brake cylinder 31 is rotatably connected to the bracket 1, the second end of the right brake cylinder 31 is rotatably connected to the first end of the right brake pedal 32, the right connecting member 33 connects the second end of the right brake pedal 32 and the bracket 1, and the second ends of the bracket 1 and the right brake pedal 32 are both rotatably connected to the right connecting member 33;

[0041] The driving assembly 4 is installed on the bracket 1 . The driving assembly 4 is connected to the right connecting member 33 . The driving assembly 4 is suitable for driving the right connecting member 33 to rotate.

[0042] According to the pedal adjustment structure of the embodiment of the present application, the right connecting member 33 is driven to rotate by the driving assembly 4, so that the right connecting member 33 rotates relative to the bracket 1, and the right connecting member 33 and the right brake pedal 32 are rotatably connected. When the right connecting member 33 rotates, the right connecting member 33 and the right brake pedal 32 rotate relative to each other. It should also be noted that the bracket 1 and the right brake pedal 32 are both rotatably connected to the right brake cylinder 31, so when the right connecting member 33 rotates, the right brake cylinder 31 also rotates. Then, the right brake pedal 32 moves, and the position of the right brake pedal 32 is adjusted, and the position of the brake pedal is adjustable, which increases the adjustable range between the driver and the pedal system, and can meet the needs of more users. In the process of the right connecting member 33 and the right brake cylinder 31 rotating, the right brake pedal 32 will rotate relative to the right connecting member 33 and the right brake cylinder 31, so that the angle of the right brake pedal 32 remains unchanged as much as possible, reducing the impact of the change in foot feel caused by the front and rear adjustment of the brake pedal.

[0043] It is understandable that the structure and adjustment method of the left brake assembly 2 are the same as those of the right brake assembly 3, and will not be repeated here.

[0044] It is understandable that the seat back of the aircraft in the related art has a 155 mm front and rear adjustment travel that can meet the driving needs of most pilots, but it is still too far forward for pilots with a height of less than 1.6 meters, making it difficult to accurately control the rudder or brake movements. Due to the fuselage structure, the seat adjustment travel cannot be significantly increased. This application adjusts the position of the brake pedal and cooperates with the front and rear adjustment of the seat back to meet the driving needs of most domestic pilots of different heights and body types.

[0045] It can be understood that the foot pedal of the present application is a suspended foot pedal, which has the advantage of being able to prevent foreign objects on the cabin floor from causing obstruction in the movement of the foot pedal.

[0046] In one embodiment of the present application, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the driving assembly 4 includes a slider 41 , which is mounted on the bracket 1 , and the right connecting member 33 is rotatably connected to the slider 41 . The slider 41 can move relative to the bracket 1 to drive the right connecting member 33 to rotate.

[0047] It is understandable that when the position of the right brake pedal 32 needs to be adjusted, the slider 41 is moved relative to the bracket 1. When the slider 41 moves, it will drive the right connecting member 33 to rotate, so that the position of the right brake pedal 32 changes, thereby realizing the adjustment of the position of the right brake pedal 32.

[0048] It can be understood that the slider 41 can rotate to drive the right connecting member to rotate, and the slider 41 can also move laterally to drive the right connecting member to rotate.

[0049] It is understandable that the movement of the slider 41 in different directions can drive the right brake pedal 32 to move in different directions, thereby achieving the front and rear adjustment of the right brake pedal 32 .

[0050] In one embodiment of the present application, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the drive assembly 4 includes:

[0051] A motor 42, the motor 42 is connected to the slider 41, and the motor 42 is used to drive the slider 41 to move, so that the right connecting member 33 rotates relative to the bracket 1; or,

[0052] A hand wheel is connected to the slider 41 , and the hand wheel is used to drive the slider 41 to move.

[0053] It is understandable that the motor 42 drives the slider 41 to move, and the movement of the slider 41 can drive the right connecting member 33 to rotate. By driving the slider 41 to move in different directions by the motor 42, the right connecting member 33 can be rotated in different directions, thereby realizing the front and rear adjustment of the right brake pedal 32.

[0054] Exemplarily, the motor 42 is, for example, a planetary gear reduction motor 42 .

[0055] Exemplarily, the motor 42 is connected to the screw rod, the motor 42 can drive the screw rod to rotate, the slider 41 is connected to the screw rod nut, the screw rod nut is connected to the screw rod, and then the motor 42 drives the screw rod to rotate to control the movement of the slider 41. The structure of the screw rod and the nut driving the slider 41 to move has the advantages of stepless adjustment and self-locking when stopped.

[0056] It is understandable that by rotating the hand wheel, the hand wheel drives the slider 41 to move, and the slider 41 drives the right connecting member 33 to rotate, thereby achieving position adjustment of the right brake pedal 32.

[0057] Exemplarily, the handwheel is connected to the slider 41 via a connecting line. The handwheel can also be connected to the slider 41 via any other suitable structure. The connection between the handwheel and the slider 41 belongs to the prior art and will not be described in detail here.

[0058] In one embodiment of the present application, the first position of the right connecting member 33 is rotatably connected to the bracket 1, the second position of the right connecting member 33 is rotatably connected to the slider 41, and the third position of the right connecting member 33 is rotatably connected to the right brake pedal 32. They are arranged in sequence along the length direction, and the slider 41 can drive the right connecting member 33 to rotate with the first position as the fulcrum.

[0059] It can be understood that the slider 41 is driven to move by the driving component 4. When the slider 41 moves, it will pull or push the second position of the right connecting member 33, so that the right connecting member 33 rotates with the first position as the fulcrum, so that the third position of the right connecting member 33 moves, thereby realizing the position adjustment of the right brake pedal 32.

[0060] Exemplarily, the first position of the right connecting member 33 is connected to the bracket 1 through a hinge, the second position of the right connecting member 33 is connected to the slider 41 through a hinge, and the third position of the right connecting member 33 is connected to the right brake pedal 32 through a hinge.

[0061] In one embodiment of the present application, the distance between the first position and the second position is smaller than the distance between the first position and the third position.

[0062] It can be understood that when the slider 41 moves, it will push or pull the second position of the right connecting member 33. Since the distance between the second position and the first position of the right connecting member 33 is smaller than the distance between the third position and the first position, according to the lever principle, the moving distance at the third position will be greater than the moving distance at the second position, that is, the slider 41 moves a smaller distance to make the third position of the right connecting member 33 move a larger distance, thereby increasing the adjustable range of the right brake pedal 32.

[0063] In one embodiment of the present application, when the right connecting member 33 and the bracket 1 are perpendicular to each other, the right connecting member 33 and the right brake cylinder 31 are parallel to each other.

[0064] It can be understood that the right connecting member 33, the right brake cylinder 31, the right brake pedal 32 and the structure between the right connecting member 33 and the right brake cylinder 31 form a structure close to a parallelogram, and the four corners of the parallelogram are rotatably connected. When the slider 41 is used to apply a thrust or a pull to the right connecting member 33, the right connecting member 33 and the right brake cylinder 31 will rotate accordingly, and the angle of the right brake pedal 32 changes very little while moving back and forth, thereby reducing the change in foot feel caused by the position adjustment of the right brake pedal 32.

[0065] It is understandable that the end of the right connecting member 33 connected to the right brake pedal 32, the right brake pedal 32, and the end of the right brake cylinder 31 connected to the right brake pedal 32 are suspended, so when the right brake cylinder 31 and the right connecting member 33 rotate, the right brake pedal 32 will rotate relative to the right brake cylinder 31 and the right connecting member 33, so that the angle of the right brake pedal 32 will not change substantially. And the suspended setting can prevent other components from affecting the adjustment and use of the brake pedal.

[0066] In one embodiment of the present application, the right connecting member 33 and the left connecting member of the left brake assembly 2 are both connected to the driving assembly 4, and the driving assembly 4 is suitable for driving the left connecting member and the right connecting member 33 to rotate synchronously.

[0067] It can be understood that by driving the right connecting member 33 and the left connecting member to rotate at the same time by the driving component 4, the position adjustment of the left brake pedal and the right brake pedal 32 is kept synchronous, thereby ensuring the consistency of the positions of the left brake pedal and the right brake pedal 32.

[0068] In one embodiment of the present application, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the pedal adjustment structure includes a rocker arm 5, which is installed on the bracket 1. The rocker arm 5 can rotate relative to the bracket 1. The first end of the rocker arm 5 is connected to the right connecting member 33 through the right connecting rod 6, and the second end of the rocker arm 5 is connected to the left connecting member of the left brake assembly 2 through the left connecting rod.

[0069] It can be understood that when the pilot performs the rudder operation, taking the right brake assembly 3 as an example, the right connecting member 33 rotates, and the right connecting member 33 drives the rocker 5 to rotate through the right connecting rod 6, and the rocker 5 drives the left connecting member to rotate, so that the left brake pedal and the right brake pedal 32 move in opposite directions.

[0070] Exemplarily, the rocker 5 is, for example, a T-shaped rocker 5 .

[0071] According to an embodiment of the second aspect of the present application, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the aircraft pedal system includes a main pilot pedal 7 and a co-pilot pedal 8, and both the main pilot pedal 7 and the co-pilot pedal 8 are provided with a pedal adjustment structure.

[0072] According to the aircraft pedal system of the embodiment of the present application, the right connecting member 33 is driven to rotate by the driving assembly 4, so that the right connecting member 33 rotates relative to the bracket 1, and the right connecting member 33 and the right brake pedal 32 are rotatably connected. When the right connecting member 33 rotates, the right connecting member 33 and the right brake pedal 32 rotate relative to each other. It should also be noted that the bracket 1 and the right brake pedal 32 are both rotatably connected to the right brake cylinder 31, so when the right connecting member 33 rotates, the right brake cylinder 31 also rotates. In this way, the right brake pedal 32 moves, and the position of the right brake pedal 32 is adjusted. In the process of the right connecting member 33 and the right brake cylinder 31 rotating, the right brake pedal 32 rotates relative to the right connecting member 33 and the right brake cylinder 31, so that the angle of the right brake pedal 32 remains as unchanged as possible, reducing the influence of the change in foot feel caused by the front and rear adjustment of the brake pedal.

[0073] It is understandable that the rocker 5 of the main driver's pedal 7 and the co-pilot's pedal 8 are connected to the left / right output torque tube through the left / right output connecting rod, and the rocker 5 structure outside the left / right output torque tube is connected to the cable-driven rudder. The present application integrates the brake pipeline into the pedal system, and the wiring is compact. When the pedal moves, most of the pipeline does not follow and deform, the local bending deformation is small, and there is no friction with other parts in the aircraft, which minimizes the premature aging of the brake oil pipe due to deformation and friction.

[0074] In one embodiment of the present application, Figure 4 As shown, the aircraft pedal system includes a synchronous link 9, which connects the main pilot pedal 7 and the co-pilot pedal 8. The synchronous link 9 makes the brake pedal at the main pilot pedal 7 and the brake pedal at the co-pilot pedal 8 move in the same manner.

[0075] It can be understood that the main driver's foot pedal 7 and the co-driver's foot pedal 8 are connected by the synchronization link 9, so that the brake pedal at the main driver's foot pedal 7 and the brake pedal at the co-driver's foot pedal 8 maintain synchronous movement.

[0076] It is to be understood that the brake pedal includes a left brake pedal and a right brake pedal 32 .

[0077] In the embodiment of the present application, the synchronization link 9 connects the rocker 5 at the main driver's foot pedal 7 and the rocker 5 at the co-driver's foot pedal 8 .

[0078] Finally, it should be noted that the above implementation modes are only used to illustrate the present application, rather than to limit the present application. Although the present application is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should be included in the scope of the claims of the present application.
