[0036] The overall structure, working principle, and technical effects of the control system 300 provided by this utility model are described in detail below with reference to the embodiments and accompanying drawings.
[0037] Please refer to Figures 1-4 The control system 300 provided by this utility model is applied to an aircraft 010 and used to control the rudder 100.
[0038] The present invention proposes an aircraft 010, including a control system 300, which is disposed within the aircraft 010.
[0039] Optionally, aircraft 010 can be an unmanned cargo aircraft, a general aviation small aircraft, etc.
[0040] In this embodiment, the aircraft 010 includes a fuselage 200, a tail compartment at the tail of the fuselage 200, a rudder 100 disposed at the tail of the fuselage 200 and rotatably connected to the fuselage 200; and a control system 300 disposed in the tail compartment.
[0041] In this embodiment, please refer to Figures 1-4 The rudder 100 is set along the third direction Z and is rotatably connected to the tail of the fuselage 200 through a rotating shaft; so that the rudder 100 can rotate around the rotating shaft, thereby realizing the steering function of the aircraft 010.
[0042] In this embodiment, the body 200 includes multiple partitions and a skin. The multiple partitions are spaced apart along the extending direction of the body 200, and the skin surrounds the multiple partitions and is riveted to the partitions.
[0043] In this embodiment, please refer to Figures 1-4 If the control system 300 is located in the tail compartment, then the fuselage 200 of the aircraft 010 located in the tail compartment includes a mounting plate 230, a first bulkhead 210 and a second bulkhead 220. The first bulkhead 210 and the second bulkhead 220 are spaced apart along a first direction X. The second bulkhead 220 includes a bulkhead body 221 and a reinforcing bulkhead 222 arranged along a second direction Y. The two ends of the reinforcing bulkhead 222 are respectively connected to the bulkhead body 221. One end of the mounting plate 230 is connected to the bulkhead body 221 and the other end is connected to the first bulkhead 210.
[0044] Please refer to Figures 1-4 The present invention proposes a control system 300, wherein the rudder 100 is arranged along the third direction Z and is rotatably connected to the aircraft 010, and the control system 300 is disposed inside the aircraft 010;
[0045] The control system 300 includes a drive unit 310, a support 320 and a rocker arm 330. The drive unit 310 and the support 320 are disposed inside the aircraft 010. The rocker arm 330 is disposed along the second direction Y and is rotatably connected to the support 320.
[0046] One end of the rocker arm 330 is connected to the output end of the drive unit 310, and the other end is connected to one side of the rudder 100. The drive unit 310 is used to drive the rocker arm 330 to rotate around the support 320 so that the rudder 100 can rotate.
[0047] Among them, the first direction X, the second direction Y, and the third direction Z are set perpendicular to each other.
[0048] It is understood that when the drive member 310 drives the rocker arm 330 to rotate clockwise around the support 320, the other end of the rocker arm 330 drives the rudder 100 to rotate counterclockwise; conversely, when the drive member 310 drives the rocker arm 330 to rotate counterclockwise around the support 320, the other end of the rocker arm 330 drives the rudder 100 to rotate clockwise. Therefore, compared to the mechanical transmission mechanism in the prior art, the control system 300 in this application, by setting up the drive member 310, the support 320, and the rocker arm 330, allows the drive member 310 to automatically control the steering direction and angle of the rudder 100. Furthermore, the control system 300 has a simple overall structure, high reliability, and occupies less space. The position of the drive member 310 can also be reasonably set according to the specific structure of the aircraft 010.
[0049] In this embodiment, the control system 300 includes a drive unit 310.
[0050] The drive unit 310 is used to drive the rocker arm 330 to rotate around the support 320 so that the rudder 100 rotates.
[0051] In this embodiment, please refer to Figures 2-4 The output end of the drive member 310 is provided with an output shaft 311 that extends and retracts along the first direction. One end of the output shaft 311 is connected to the output end of the drive member 310, and the other end is rotatably connected to one end of the rocker arm 330.
[0052] Optionally, the other end of the output shaft 311 is provided with a first hinge portion, the first hinge portion is provided with a first groove, one end of the rocker arm 330 is located in the first groove, and the first hinge portion provided at the other end of the output shaft 311 is hinged to one end of the rocker arm 330 through a first hinge shaft.
[0053] Optionally, the drive unit 310 can be a servo motor.
[0054] It is understandable that by setting up the drive unit 310, which is connected to the external flight control system, the drive unit 310 can automatically control the steering direction and angle of the rudder 100 by operating on the external flight control system.
[0055] In this embodiment, please refer to Figures 2-4 The aircraft 010 has an internal mounting plate 230, and a mounting base 231 is fixed on the mounting plate 230. The mounting base 231 is rotatably connected to one end of the drive component 310 so that the mounting base 231 can be rotatably set around the first direction X.
[0056] The drive member 310 has a connecting part 312 extending from its housing. The mounting base 231 has a second hinge part with a second groove. The connecting part 312 is located in the second groove. The connecting part 312 of the drive member 310 and the second hinge part of the mounting base 231 are hinged together by a second hinge shaft.
[0057] Understandably, the drive component 310 is rotatably connected to the mounting assembly, enabling the drive component 310 to adapt to multi-degree-of-freedom motion and avoiding motion interference caused by rigid connections, which is especially suitable for scenarios requiring complex angle adjustments; it also eliminates the need for high-precision installation and positioning of the hinge, reducing the difficulty of processing and assembly; at the same time, during the change of direction of the control system 300, the hinge structure can buffer instantaneous torque changes, reduce the oscillation of the control system 300, and improve the control accuracy of the drive component 310.
[0058] In this embodiment, the control system 300 includes a support 320 and a rocker arm 330.
[0059] In this embodiment, please refer to Figures 2-4 The support 320 is disposed on the first partition 210 and located on the side away from the second partition 220. The rocker arm 330 is disposed along the second direction Y and is rotatably connected to the support 320.
[0060] Optionally, the support 320 is hinged to the midpoint of the rocker arm 330. The support 320 is provided with a third groove along the second direction Y, the rocker arm 330 passes through the third groove, and the midpoint of the rocker arm 330 is hinged to the support 320 through a third hinge axis.
[0061] In this embodiment, the first partition 210 has a first opening 211 and a second opening 212 at both ends relative to the rocker arm 330. The output shaft 311 of the output end of the drive member 310 passes through the first opening 211 and is connected to one end of the rocker arm 330 for transmission.
[0062] Understandably, this configuration of the control system 300 allows it to be integrated with the overall structure of the fuselage, enabling the drive unit 310 to be designed in a reasonable position and making good use of the space in the tail section.
[0063] In this embodiment, the control system 300 includes a linkage 340.
[0064] The connecting rod 340 is used to connect the rudder 100 and the other end of the rocker arm 330.
[0065] In this embodiment, please refer to Figures 1-4 The rudder 100 has a first side and a second side that are arranged opposite to each other along the first direction X. The drive member 310 is located opposite to the first side of the rudder 100. The second side of the rudder 100 is provided with a connecting seat 110, and the other end of the rocker arm 330 is rotatably connected to the connecting seat 110.
[0066] In this embodiment, the control system 300 further includes a link 340 arranged along the first direction X. One end of the link 340 is rotatably connected to the other end of the rocker arm 330, and the other end is rotatably connected to one side of the rudder 100.
[0067] Furthermore, the connecting rod 340 has a fourth hinge portion at both ends, and a fourth groove is provided in the fourth hinge portion; the other end of the rocker arm 330 is located in the fourth groove, and one end of the connecting rod 340 is hinged to the other end of the rocker arm 330 through the fourth hinge shaft; the connecting seat 110 on the rudder 100 is located in the fourth groove, and the other end of the connecting rod 340 is hinged to the connecting seat 110 of the rudder 100 through the fourth hinge shaft.
[0068] It is worth mentioning that the length of the connecting rod 340 is adjustable, and the drive component 310 can be designed in a reasonable position according to the length of the connecting rod 340.
[0069] In this embodiment, please refer to Figure 1 The drive component 310, support 320, rocker arm 330 and connecting rod 340 are located on the same plane.
[0070] Optionally, the drive member 310, support 320, rocker arm 330, and connecting rod 340 may be located on a horizontal plane inclined relative to the first direction X. Of course, the drive member 310, support 320, rocker arm 330, and connecting rod 340 may be located on a horizontal plane arranged along the first direction X.
[0071] Understandably, by making the drive unit 310, support 320, rocker arm 330 and connecting rod 340 of the control system 300 coplanar, the three-dimensional mechanical transmission mechanism of the prior art can be eliminated, reducing manufacturing and maintenance costs. At the same time, the control system 300 has a simple structure and reduces the steering components of the prior art, thereby improving the reliability of the control system 300 in controlling the rudder 100.
[0072] The working principle and process of the control system 300 provided in this embodiment of the utility model are as follows:
[0073] When the output shaft 311 of the drive unit 310 retracts, and the output shaft 311 drives the rocker arm 330 to rotate clockwise around the support 320, the other end of the rocker arm 330 pulls the rudder 100 to rotate counterclockwise through the connecting rod 340.
[0074] When the output shaft 311 of the drive unit 310 extends out and drives the rocker arm 330 to rotate counterclockwise around the support 320, the other end of the rocker arm 330 pushes the rudder 100 to rotate clockwise through the connecting rod 340.
[0075] In summary, the control system 300 and aircraft 010 provided in this embodiment of the present invention, by setting up a drive component 310, a support 320 and a rocker arm 330, enable the drive component 310 to automatically control the steering direction and angle of the rudder 100. Compared with the mechanical transmission mechanism in the prior art, the control system 300 proposed in this application has a simple overall structure, high reliability, and occupies less space. Furthermore, the position of the drive component 310 can be reasonably set according to the specific structure of the aircraft 010.
[0076] The above are merely specific embodiments of this utility model, but the protection scope of this utility model 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 utility model should be included within the protection scope of this utility model.
