DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0030] The purpose of the present application is to provide an aircraft roll wing, which controls the deflection angle of blade oscillation to obtain sufficient lift and appropriate lateral thrust.

[0031] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments. The fixation in the embodiments can be detachable fixation, such as fixation by screws, or non-detachable fixation, such as fixation by welding. The parallel in the embodiments does not include coincidence.

[0032] With reference to Figures 1-6 , the present embodiment provides an aircraft roll wing, which comprises a fixed plate 1, a blade 2, a blade rotating driving device, an eccentric mechanism 4 and an eccentric disc deflection driving mechanism 6.

[0033] The fixed plate 1 is used to be fixedly connected with an aircraft. The number of the blades 2 is multiple. The blade rotating driving device is used to drive the blades 2 to rotate, and comprises a support 3. The support 3 is rotatably installed on the fixed plate 1, and the rotating axis of the support 3 is parallel to the length direction of the blades 2. The support 3 is used to be connected with a support driving mechanism 5, so as to rotate around the axis of the support 3 under the driving of the support driving mechanism 5. The support 3 has multiple blade mounting ends, which are uniformly distributed along the circumferential direction around the rotating axis of the support 3, and each blade mounting end is rotatably connected with the first end of one of the blades 2. When the support 3 rotates, the blades 2 are driven to rotate. The eccentric mechanism 4 is used to swing the blades 2 when rotating, and comprises an eccentric disc 41, a rotating disc 42 and multiple connecting rods 43. The rotating disc 42 is rotatably installed on the eccentric disc 41 and coaxial with the eccentric disc 41, and the axis of the rotating disc 42 is parallel to the rotating axis of the support 3. The rotating disc 42 has multiple connecting rod mounting ends, which are uniformly distributed along the circumferential direction around the rotating axis of the rotating disc 42, and each connecting rod mounting end is rotatably connected with the first end of one of the connecting rods 43. The second end of each of the blades 2 is rotatably connected with the second end of one of the connecting rods 43. The eccentric disc deflection driving mechanism 6 is connected with the eccentric disc 41, and is used to drive the eccentric disc 41 to rotate around the rotating axis of the support 3.

[0034] The working principle of the aircraft rolling wing of the embodiment is as follows: when the support driving mechanism 5 works and the eccentric disc deflection driving mechanism 6 does not work, the first end of the blade 2 rotates around the rotating axis of the support 3, the first end of the connecting rod 43 rotates around the rotating axis of the rotating disc 42, and the movements of the first end of the blade 2 and the first end of the connecting rod 43 are not synchronized, so the included angle of the connection between the blade 2 and the connecting rod 43 changes, thereby realizing the swinging of the blade 2. In the above process, the position of the eccentric disc 41 is fixed, and the rotating and swinging powers of the blade 2 come from the support driving mechanism 5. In addition, the eccentric disc 41 can be rotated by a certain angle around the rotating axis of the support 3 through the eccentric disc deflection driving mechanism 6, and the rotating disc 42 is driven to move synchronously by the eccentric disc 41. In this way, the movement track of the first end of the connecting rod 43 can be changed, so that the angle of the first end of the blade 2 is different at the same position, thereby the blade 2 obtains different lift and lateral thrust, and the purpose of controlling the flight state is achieved.

[0035] The specific way of rotatably installing the support 3 on the fixed plate 1 is various, and the person skilled in the art can select according to the actual needs.

[0036] For example, referring to Figures 1-4 , as the embodiment 1 of the embodiment, the aircraft rolling wing further comprises a central rotating shaft 7, the central rotating shaft 7 is rotatably installed on the fixed plate 1, the rotating axis of the central rotating shaft 7 is collinear with the axis of the central rotating shaft 7, the central rotating shaft 7 is fixedly connected with the support 3 and the rotating axes are collinear. By driving the central rotating shaft 7 to rotate, the support 3 can be driven to rotate.

[0037] Further, referring to Figures 1-4 , the aircraft roll wing of embodiment 1 further comprises a support driving mechanism 5, which comprises a first driven pulley 51, a first driving belt 52, a first driving pulley 53 and a first driving device 54. The first driving device 54 is fixed on the fixed plate 1 and connected with the first driving pulley 53 to drive the first driving pulley 53 to rotate around its own axis. The first driven pulley 51 is fixed on the central rotating shaft 7 and has the same rotating axis as the central rotating shaft 7 to drive the central rotating shaft 7 to rotate. The first driving belt 52 is simultaneously sleeved outside the first driving pulley 53 and the first driven pulley 51 to connect the first driving pulley 53 and the first driven pulley 51 in transmission. The support driving mechanism 5 drives the central rotating shaft 7 to rotate in the form of belt transmission, thereby driving the support 3 to rotate. Figures 1-3 In the embodiment, the central rotating shaft 7 is of solid structure. Figure 4 In the embodiment, the central rotating shaft 7 is of hollow structure.

[0038] For another example, referring to Figures 5-6 , as embodiment 2 of the present embodiment, the aircraft roll wing further comprises an inner tube 8 fixedly connected with the fixed plate 1, the inner tube 8 penetrating through the support 3 and being rotationally connected with the support 3, and the rotating axis of the support 3 is collinear with the axis of the inner tube 8.

[0039] Further, referring to Figures 5-6 , the aircraft roll wing of embodiment 2 further comprises a support driving mechanism 5, which comprises a first driven pulley 51, a first driving belt 52, a first driving pulley 53 and a first driving device 54. The first driving device 54 is fixed on the fixed plate 1 and connected with the first driving pulley 53 to drive the first driving pulley 53 to rotate around its own axis. The first driven pulley 51 is fixed on the support 3 and has the same rotating axis as the support 3 to drive the support 3 to rotate. The first driving belt 52 is simultaneously sleeved outside the first driving pulley 53 and the first driven pulley 51 to connect the first driving pulley 53 and the first driven pulley 51 in transmission.

[0043] In the embodiment, the eccentric disc deflection driving mechanism 6 includes a second driven pulley 61, a second driving belt 62, a second driving pulley 63 and a second driving device 64. The second driving device 64 is fixed on the fixed plate 1 and is connected with the second driving pulley 63 to drive the second driving pulley 63 to rotate around its axis. The second driven pulley 61 is fixed on the eccentric disc 41 and has the same rotating axis as the support 3 to drive the eccentric disc 41 to rotate. The second driving belt 62 is sleeved outside the second driving pulley 63 and the second driven pulley 61 to drive the second driving pulley 63 and the second driven pulley 61. When the second driving device 64 works, the second driving pulley 63 is driven to rotate, the second driving pulley 63 drives the second driven pulley 61 to rotate through the second driving belt 62, and the second driven pulley 61 drives the eccentric disc 41 to rotate.
