Description

Technical Field

[0001] The present application belongs to the technical field of unmanned aerial vehicles, and in particular to a flight control installation structure for a fixed-wing unmanned aerial vehicle. Background Art

[0002] With the rapid development of the UAV field, fixed-wing UAVs are increasingly being used in production and life. Unmanned aircraft, referred to as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by on-board computers. The flight control plays a vital role in the normal flight of UAVs. The UAV flight control is the central control component of the UAV. It is responsible for controlling and managing all aspects of the aircraft to ensure that the UAV can perform flight missions stably, safely and reliably; it is the control center of the UAV and plays a decisive role in the normal operation of the UAV.

[0003] Fixed-wing drones are large in size and usually require more sensors, interfaces, and computing resources, so the flight control needs a larger area to accommodate these components. In the prior art, installing the flight control inside the fuselage will, on the one hand, take up the load space and weaken the drone's load performance to a certain extent; on the other hand, the flight control needs to be maintained or replaced. The flight control is installed inside the drone, and the drone's shell or other components need to be disassembled before it can be operated. This will increase the complexity and time cost of maintenance, especially in the wild environment or in bad weather.

[0004] In view of the above problems, the appropriate flight control installation position is a problem that needs to be considered in modern UAV design. In order to solve the problem of UAV flight control installation, this paper proposes a fixed-wing UAV flight control installation structure. Utility Model Content

[0008] The bosses include an upper boss, a middle boss, and a lower boss;

[0009] The upper boss is connected to the middle boss via a first low-position connecting piece, and the middle boss is connected to the lower boss via a second low-position connecting piece.

[0010] Furthermore, the first low-position connecting member and the second low-position connecting member are both connecting members with an inclination, and the inclination of the first low-position connecting member is consistent with the inclination of the second low-position connecting member; the flight control is installed on the middle-level boss and can be placed on the lower-level boss, and an installation space is provided for the flight control between the lower-level boss and the middle-level boss; a screw column is provided on the upper-level boss for installing the flight control cover; the second low-position connecting member is provided with a threading hole for introducing the flight control connecting line, and is fixed to the second low-position connecting member with a wire clip.

[0011] Furthermore, the position of the boss is selected to avoid the main load-bearing components and the wing main beam, and the boss is designed together with the wing, and the whole is molded in batches without setting a separation surface, thereby reducing the impact on the strength of the wing.

[0012] Beneficial effects of the technical solution of this application:

[0013] In this application, the flight control is installed in the middle wing, which can make full use of the idle space of the fuselage without occupying the load space, thus improving the carrying performance of the UAV to a certain extent.

[0014] The present application installs the flight control in the rear half of the wing, does not damage the wing main beam and the torsion box, and forms a sunken and concave overall shape, which has little effect on the wing strength.

[0015] In the present application, the boss is sunken into a plane, which is convenient for installing the flight control, and is located near the center of the drone, so it is sensitive to the change of the drone's attitude.

[0016] In the present application, the bosses are multi-layer steps, and the joints are inclined, which increases the overall streamline of the drone, does not affect the overall shape and normal flight of the drone, and is easy to disassemble, facilitating the maintenance of the flight control.
