Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0019] In this embodiment, refer to Figure 1 and Figure 3 It includes a mounting base 2, the surface of which has multiple mounting through holes for connecting the mounting base 2 and the aircraft.

[0020] In this embodiment, refer to Figure 2 A cavity is provided through the middle of the mounting base 2. A rudder 5 is installed in the upper port of the cavity. A folding rudder 1 is connected to the end of the rudder 5 away from the cavity. An adapter plate 3 is installed outside the lower port of the cavity. A push rod 4 is connected to the adapter plate 3. A linkage mechanism is provided in the cavity. The linkage mechanism is used to make the adapter plate 3 rotate synchronously with the folding rudder 1.

[0021] In this embodiment, refer to Figure 2The linkage mechanism includes a bushing 9, a rotating shaft 11, a first bearing 7, and a second bearing 10. The bushing 9 is rotatably installed in the cavity. The upper end of the bushing 9 is fixedly connected to the rudder 5. The first bearing 7 and the second bearing 10 are fixedly sleeved on the bushing 9. The rotating shaft 11 is sleeved on the lower end of the bushing 9. The rotating shaft 11 is also connected to the adapter plate 3. A first step and a second step are provided along the circumference of the cavity. The first bearing 7 is installed on the first step, and the second bearing 10 is installed on the second step, so that the first bearing 7 and the second bearing 10 can be stably installed in the mounting base 2.

[0022] Reference Figure 1 and Figure 2 The rudder handle 5 and the adapter plate 3 are connected to the two ends of the bushing 9 respectively. The first bearing 7 and the second bearing 10 are sleeved on the bushing 9, so that the bushing 9 can rotate in the mounting base 2. When the adapter plate 3 rotates, the rudder handle 5 and the folding rudder 1 are linked to the adapter plate 3 through the bushing 9, so that the force transmission path is shortened.

[0023] Among them, reference Figure 2 , Figure 5 and Figure 7 The outer side of the bushing 9 is composed of a connecting part 901, a first shoulder 902, a second shoulder 903, a third shoulder 904, and a bottom shaft section 905. The diameters of the connecting part 901, the first shoulder 902, the second shoulder 903, the third shoulder 904, and the bottom shaft section 905 are distributed in a stepped decreasing pattern. The surface of the connecting part 901 is provided with a plurality of first connecting holes 9011. The connecting part 901 is fixedly connected to the rudder 5. The first bearing 7 is sleeved on the first shoulder 902, the second bearing 10 is sleeved on the second shoulder 903, and a round nut 8 is sleeved on the third shoulder 904. The round nut 8 is used to limit the second bearing 10 to prevent the second bearing 10 from falling off. The rotating shaft 11 is fixedly sleeved on the bottom shaft section 905 to realize the fixed connection between the adapter plate 3 and the bushing 9.

[0024] In this embodiment, refer to Figure 4The rudder 5 is divided into a first connecting section 504, a second connecting section 505, and a third connecting section 506. The first connecting section 504 consists of two parallel vertical plates with multiple mounting holes 501 on each plate. The folding rudder 1 is installed between the two vertical plates and also has a pre-set mounting hole. The folding rudder 1 is fixedly connected to the first connecting section 504 by using rivets 12 to pass laterally through the mounting holes 501. The second connecting section 505 is disc-shaped on the outside and has a second connecting hole 502 on its surface. The surface of the connecting part 901 and the second connecting section 505 are fixedly connected by using bolts to pass through the first connecting hole 9011 and the second connecting hole 502 in sequence. The third connecting section 506 extends into the interior of the connecting part 901 to achieve a coaxial connection between the bushing 9 and the rudder 5.

[0025] In this embodiment, refer to Figure 2 and Figure 4 The second connecting section 505 has a sealing groove 503 on its outer periphery, and a sealing ring 6 is fitted inside the sealing groove 503. The sealing ring 6 also abuts against the side wall of the cavity to ensure a sealed connection between the mounting base 2 and the rudder 5.

[0026] In this embodiment, refer to Figure 5 and Figure 6 The bottom shaft section 905 has a square shape on the outside, and the rotating shaft 11 has a square hole through it. The bottom shaft section 905 is fitted into the square hole to achieve the snap-fit ​​between the rotating shaft 11 and the bushing 9, and at the same time, it is convenient to drive the bushing 9 to rotate synchronously through the rotating shaft 11.

[0027] In this embodiment, refer to Figure 1 , Figure 2 and Figure 6 A protrusion 1101 is provided on the rotating shaft 11, and a through hole is provided on the protrusion 1101. The adapter plate 3 is in the shape of "I". Through holes are opened on both sides of the adapter plate 3. The protrusion 1101 is located on one side of the adapter plate 3. The protrusion 1101 is fixedly connected to the adapter plate 3 by passing screws through the through holes. A push rod 4 is installed on the other side of the adapter plate 3. The push rod 4 is also fixedly connected to the adapter plate 3 by passing screws through the through holes. The rotating plate can be rotated clockwise or counterclockwise by pushing the push rod 4.

[0028] The working principle of this invention is as follows: When the push rod 4 is pushed, the push rod 4 causes the adapter plate 3 to rotate clockwise or counterclockwise, which in turn causes the bushing 9 to rotate, thereby causing the folding rudder 1 to rotate in the same direction as the adapter plate 3. This achieves a short force transmission path between the adapter plate 3 and the folding rudder 1, thereby effectively improving the response speed of the folding rudder 1 and further improving the reliability of the folding rudder 1.
