Description

Technical Field

[0001] This utility model relates to the technical field of model aircraft, specifically a main wing opening and closing structure. Background Technology

[0002] The wing of a model airplane refers to the wing structure of the aircraft, used to provide lift and control the aircraft's attitude. A wing typically consists of a main wing and ailerons. The main wing is the primary lift component, while the ailerons control the aircraft's roll and pitch.

[0003] Existing technologies use a rocker arm servo to control the retraction and extension of the left and right main wings, which requires a large space. This is practical for large fixed-wing aircraft but not suitable for small fixed-wing aircraft. Therefore, we propose a main wing opening and closing structure. Utility Model Content

[0004] The purpose of this invention is to provide a main wing opening and closing structure to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a main wing opening and closing structure, including a fuselage, a first main wing, and a second main wing. A crossbeam is installed on the fuselage. The first main wing is rotatably installed between one end of the crossbeam and the fuselage, and the second main wing is rotatably installed between the other end of the crossbeam and the fuselage. A first right-angle rotating shaft and a second right-angle rotating shaft are rotatably installed in the middle of the crossbeam. The first right-angle rotating shaft is connected to the first main wing through a first adjustable connecting rod, and the second right-angle rotating shaft is connected to the second main wing through a second adjustable connecting rod. A drive assembly for driving the first right-angle rotating shaft and the second right-angle rotating shaft to rotate is installed in the middle of the fuselage.

[0006] Preferably, the drive assembly includes a linear servo, a slider, a first transmission wire, and a second transmission wire. The linear servo drives the slider to reciprocate. The slider is connected to a first right-angle shaft via the first transmission wire, and the slider is connected to a second right-angle shaft via the second transmission wire.

[0007] Preferably, the two ends of the first transmission steel wire are rotatably connected to the slider and the first right-angle rotating shaft, respectively, and the two ends of the second transmission steel wire are rotatably connected to the slider and the second right-angle rotating shaft, respectively.

[0008] Preferably, the crossbeam is equipped with a first guide rail that mates with the first main wing, and the crossbeam is equipped with a second guide rail that mates with the second main wing.

[0009] Preferably, the two ends of the first adjustable link are rotatably connected to the first right-angle rotating shaft and the first main wing, respectively, and the two ends of the second adjustable link are rotatably connected to the second right-angle rotating shaft and the second main wing, respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The linear servo's lead screw rotation drives the slider to move back and forth in a linear motion, which in turn pushes the transmission wire forward, causing the left right-angle shaft to rotate counterclockwise around the rotation axis and the right right-angle shaft to rotate clockwise, driving the adjustable connecting rod to move outward in an outward unfolding motion. In this way, the first and second main wings can achieve the opening and closing action.

[0012] 2. The crossbeam is equipped with a first guide rail that mates with the first main wing, and the crossbeam is equipped with a second guide rail that mates with the second main wing, which makes the opening and closing stability of the first and second main wings better.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0018] Please see Figure 1-2In this embodiment of the present invention, a main wing opening and closing structure includes a fuselage 1, a first main wing 13, and a second main wing 14. A crossbeam 2 is installed on the fuselage 1. The first main wing 13 is rotatably installed between one end of the crossbeam 2 and the fuselage 1, and the second main wing 14 is rotatably installed between the other end of the crossbeam 2 and the fuselage 1. A first right-angle rotating shaft 7 and a second right-angle rotating shaft 8 are rotatably installed in the middle of the crossbeam 2. The first right-angle rotating shaft 7 is connected to the first main wing 13 through a first adjustable connecting rod 9, and the second right-angle rotating shaft 8 is connected to the second main wing 14 through a second adjustable connecting rod 10. The two ends of the first adjustable connecting rod 9 are rotatably connected to the first right-angle rotating shaft 7 and the first main wing 13, respectively. The two ends of the second adjustable connecting rod 10 are rotatably connected to the second right-angle rotating shaft 8 and the second main wing 14, respectively. A drive assembly for driving the first right-angle rotating shaft 7 and the second right-angle rotating shaft 8 to rotate is installed in the middle of the fuselage 1.

[0019] The drive assembly includes a linear servo 3, a slider 4, a first transmission wire 5, and a second transmission wire 6. The linear servo 3 drives the slider 4 to reciprocate. The slider 4 is connected to a first right-angle rotating shaft 7 via the first transmission wire 5, and to a second right-angle rotating shaft 8 via the second transmission wire 6. The two ends of the first transmission wire 5 are rotatably connected to the slider 4 and the first right-angle rotating shaft 7, respectively. The two ends of the second transmission wire 6 are rotatably connected to the slider 4 and the second right-angle rotating shaft 8, respectively. The rotation of the lead screw of the linear servo drives the slider to move forward and backward in a linear motion, thereby pushing the transmission wire forward and causing the left right-angle rotating shaft to rotate counterclockwise around the rotation axis, and the right right-angle rotating shaft to rotate clockwise, driving the adjustable connecting rod to move outward in an outward unfolding motion. In this way, the first main wing 13 and the second main wing 14 can realize the opening and closing action.

[0020] The crossbeam 2 is equipped with a first guide rail 11 that cooperates with the first main wing 13, and the crossbeam 2 is equipped with a second guide rail 12 that cooperates with the second main wing 14, so that the opening and closing stability of the first main wing 13 and the second main wing 14 is better.

[0021] The working principle of this utility model is as follows: the lead screw of the linear servo rotates, causing the slider to move back and forth in a linear motion, thereby pushing the transmission steel wire forward and causing the left right-angle rotating shaft to rotate counterclockwise around the rotating axis, and the right right-angle rotating shaft to rotate clockwise, causing the adjustable connecting rod to move outward in an outward unfolding manner, so that the first main wing 13 and the second main wing 14 can realize the opening and closing action.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
