The driving mechanism 60 is installed on the wing body 10, and the driving mechanism 60 is connected with the wing tip 20, and the wing tip 20 can be switched between the first preset position and the second preset position relative to the wing body 10 under the driving of the driving mechanism 60, so as to realize the switching of the power device 30 between the horizontal state and the vertical state.

[0036] For the above wing body 10, as shown in the drawings, Figure 3 The wing body 10 comprises a wing shell 11 and a first support frame 12. The first support frame 12 is accommodated inside the wing shell 11, and the first support frame 12 is used to install the rotating shaft 50 and the driving mechanism 60.

[0037] The first support frame 12 comprises a first connecting rod 122, a first mounting plate 123 and a second mounting plate 124, the first connecting rod 122 is fixed with the first mounting plate 123 and the second mounting plate 124 respectively, and the first support frame 12 is in a truss structure, which mainly bears a large axial tension or pressure, and the axial force is uniformly distributed. Compared with a solid beam structure using the same material, the self-weight can be reduced and the stiffness can be increased. The first mounting plate 123 and the second mounting plate 124 are both provided with a first through hole 121, that is, there are two first through holes 121, one first through hole 121 is arranged on the first mounting plate 123, and the other first through hole 121 is arranged on the second mounting plate 124. The two first through holes 121 are used for inserting the rotating shaft 50, one end of the rotating shaft 50 penetrates through the first through hole 121, and the middle part of the rotating shaft 50 penetrates through the other first through hole 121, so that the rotating shaft 50 is fixed on the first mounting plate 123 and the second mounting plate 124. The rotating shaft 50 is simultaneously borne on the first mounting plate 123 and the second mounting plate 124, which is more firm and stable. In some embodiments, the cross section of the first through hole 121 is a cut-off rectangular shape, and the cross section of the part of the rotating shaft 50 inserted into the first through hole 121 is also a cut-off rectangular shape, so that when the first through hole 121 cooperates with the rotating shaft 50, the circumferential rotation of the rotating shaft 50 can be limited, and the rotating shaft 50 is more convenient to fix.

[0040] For the above wing tip 20, as shown in Figure 4 The wing tip 20 comprises a wing tip shell 21 and a second support frame 22, and the second support frame 22 is accommodated in the wing tip shell 20.

[0041] The second support frame 22 includes a second connecting rod 222, a third mounting plate 223, and a fourth mounting plate 224.

The other end of the rotating shaft 50 passes through both second through holes 221, and the rotating shaft 50 can rotate relative to the second through holes 211, allowing the wingtip shell 21 to rotate around the rotating shaft 50. In some embodiments, the cross-section of the second through holes 221 is circular, and the portion of the rotating shaft 50 inserted into the second through holes 221 is also circular, allowing the rotating shaft 50 to rotate within the second through holes 211.

[0042] In some embodiments, the wingtip housing 21 is further provided with a second maintenance port (not shown), and the wingtip 20 also includes a second cover 211, which is provided at the second maintenance port of the wingtip housing 21 and is used to open or close the second maintenance port to facilitate the inspection and maintenance of components located in the wingtip 20.

The outer contours of the two first limiting blocks 53 are square, and the two first limiting blocks 53 are respectively housed in the first through hole 121. The first limiting blocks 53 are engaged with the first through hole 121 so that the rotating shaft 50 cannot rotate relative to the first through hole 121.

[0044] It can be understood that the way to fix the rotating shaft 50 and the first support frame 12 is not limited to the above structure, and can also be realized by other structures, for example: the first support frame 12 further comprises a locking rod (not shown in the figure), the number of the locking rod is two, the first mounting plate 123 and the second mounting plate 124 are further provided with fourth through holes (not shown in the figure), the rotating shaft 50 is further provided with fifth through holes (not shown in the figure), the number of the fourth through holes and the fifth through holes is four, the fourth through holes are arranged around the first mounting plate 123 and the second mounting plate 124 along the radial direction of the rotating shaft 50, the fifth through holes are arranged on the rotating shaft 50 corresponding to the fourth through holes, the locking rod crosses the fourth through holes and the fifth through holes, and the locking rod insertion part is a mortise and tenon structure.

The surface of the first driving piece 62 away from the first driving device 61 is provided with a first sliding table 621. The first sliding groove 63 is arranged on the surface of the third mounting plate 223 facing the second mounting plate 124, the first sliding table 621 is inserted into the first sliding groove 63, and the first sliding table 621 can slide along the first sliding groove 63. When the first driving device 61 drives the first driving piece 62 to rotate, the first sliding table 621 slides along the first sliding groove 63, thereby driving the wing tip 20 to rotate relative to the wing body 10. In some embodiments, the first sliding table 621 is a cylinder, which is conducive to reducing the sliding resistance of the first sliding table 621 in the first sliding groove 63. Wherein, when the wing body 10 and the wing tip 20 are flush, the second mounting plate 124 and the third mounting plate 223 are attached, and the first driving rod 62 is accommodated in the accommodation gap 1241, so that the tiltable wing 1 is more beautiful.

[0046] It should be noted that, as shown in Figure 11 the driving mechanism 60 can drive the wing tip 20 relative to the wing body 10, and can be tilted at any angle within plus or minus 130 degrees of the horizontal plane as 0 degree.

[0047] It can be understood that the mounting mode of the driving mechanism 60 is not limited to the above mode, the third mounting plate 223 is further provided with a receiving groove (not shown), the driving mechanism 60 further comprises a second driving device (not shown), a second driving piece (not shown) and a second sliding groove (not shown), wherein the second driving piece is further provided with a second sliding table (not shown), the second driving device is mounted on a fourth mounting plate 224, a driving shaft of the second driving device is fixed with the second driving piece after penetrating through the fourth mounting plate 224, the second sliding groove is arranged on a surface of the second mounting plate 124 facing the third mounting plate 223, the second mounting plate 124 and the third mounting plate 223 are attached when the wing body 10 and the wing tip 20 are flush, the second driving piece is received in the receiving groove, the second sliding table is inserted into the second sliding groove, the second sliding table can slide along the second sliding groove, and the second sliding table slides along the second sliding groove when the second driving device drives the second driving piece to rotate, so as to drive the wing tip 20 to rotate relative to the wing body 10.

[0048] In the embodiment of the present application, the tiltable wing 1 comprises a wing body 10, a wing tip 20, a power device 30, a cable 40, a rotating shaft 50 and a driving mechanism 60. The power device 30 is mounted on the wing tip 20, one end of the cable 40 is connected with the power device 30, the rotating shaft 50 is rotationally connected with the wing body 10 and the wing tip 20 respectively, the rotating shaft 50 is provided with a through hole in the axial direction, the other end of the cable 40 extends into the wing body 10 through the through hole, and the driving mechanism 60 is used for driving the wing tip 20 to rotate around the rotating shaft 50, so that the power device 30 can be switched between a preset first position and a preset second position relative to the wing body 10, and the power device 30 can be switched between a horizontal state and a vertical state. Since the cable 40 extends into the wing body 10 through the through hole in the axial direction of the rotating shaft 50, and the driving mechanism 60 and the cable 40 are separated, the cable 40 will not be wound around the driving shaft of the driving mechanism 60 due to the tilting movement of the driving mechanism 60, and will not be constantly folded and opened along the driving shaft of the driving mechanism 60, thereby reducing the risk of the cable 40 being torn.
