[0049] The specific technical solutions in the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0050] This invention provides a wing auxiliary installation mechanism for a fixed-wing unmanned aerial vehicle (UAV), including support components. Each support component consists of a tray, a floating mechanism, a lifting mechanism, and a main frame. The tray provides support and protects the wing with felt. The floating mechanism enables the tray to roll. The lifting mechanism enables lifting and is equipped with an auxiliary support rod to ensure stability during the lifting process.

[0051] Figure 1 , Figure 7 The fixed-wing UAV wing auxiliary installation mechanism provided in this embodiment of the invention includes two support components 1.

[0052] refer to Figure 2The support assembly 1 includes a main frame 14, a lifting mechanism 13 installed within the main frame 14, and a tray 11 mounted on the lifting mechanism 13. Each support assembly 1 has a crossbeam mounting plate at each of the four corners of its two sides parallel to the XZ plane; two crossbeams 2, bolted to the crossbeam mounting plates, connect two support assemblies 1. The crossbeams 2 are freely detachable, and their length is adapted to the wing. For different wing lengths, the length of the crossbeams 2 can be changed to adjust the distance between the two support assemblies so that the wing lies flat on the tray. In other embodiments of the invention, the support assembly 1 can also be used independently.

[0053] refer to Figure 6 The main frame 14 has a frame connecting plate near the top and casters 141 at the bottom; there are four casters 141, located at the four bottom corners of the main frame 14.

[0054] Let the length of the main frame 14 be the X-axis, the width be the Y-axis (heading), and the height be the Z-axis (lifting).

[0055] refer to Figure 5 The lifting mechanism 13 includes a screw jack 131 arranged along the Z-axis, a coupling 136 located at the input end of the screw jack 131, a lifting mechanism input shaft 135 connected to the coupling 136, and symmetrically arranged and paired linear bearings 133 and lifting rods 132 passing through the linear bearings 133. The coupling 136 and linear bearings 133 are mounted on a frame connecting plate. A coupling mounting hole is opened in the center of the frame connecting plate, and the screw jack 131 is mounted on the frame connecting plate, with the output shaft of the screw jack 131 passing through the coupling mounting hole. Lifting mounting holes are opened at two opposite corners of the frame connecting plate, and two linear bearings 133 are respectively installed in the two lifting mounting holes. There are two lifting rods 132, which are respectively connected to the two opposite corners of the tray base 115 to increase lifting stability and prevent the center of gravity from tilting and bending the lifting mechanism 13 when lifting to a higher position, thus playing a role in straightening and stabilizing. The screw jack 131 uses a coupling 136 to convert the rotational motion of the input shaft 135 of the lifting mechanism into the lifting motion of the output shaft along the Z-axis. (This achieves lifting)

[0056] Both ends of the lifting mechanism input shaft 135 are equipped with detachable handwheels 134. The lifting mechanism input shaft 135 can be rotated by the handwheels 134 or other power tools to lift the pallet 11 of the lifting mechanism 13, thereby raising the wing.

[0057] refer to Figure 3The pallet 11 includes a pallet base 115, two pallet frames 114 respectively disposed at both ends of the pallet base 115, and a pallet body 111 located on the two pallet frames 114. A floating mechanism 12 is provided at the center of the pallet base 115. The output shaft of the screw jack 131 is connected to the pallet base 115, and the lifting rod 132 is connected to the corresponding positions of the two pallet frames 114 on the pallet base 115. Two attitude adjustment screws 113 are provided along the Y-axis between each pallet frame 114 and the pallet body 111 for attitude adjustment of the pallet body 111, and the principle is similar to that of the leveling screw. The upper surface of the pallet body 111 is covered with felt as a cushioning material, and the felt is in direct contact with the wing to protect the outer surface of the wing. Handles 112 are symmetrically provided at the lower ends of both ends of the pallet body 111, and baffles are symmetrically provided at the top. The handles 112 are designed to facilitate attitude adjustment by the operator.

[0058] The pallet frame 114 is a Z-shaped plate, including an upper end plate, a connecting plate and a lower end plate connected in sequence. The lower end plate is fixedly connected to the pallet base 115. The upper end plate has two threaded holes evenly opened along the Y-axis direction, and the attitude adjustment screws 113 are set in the threaded holes.

[0059] refer to Figure 4 The floating mechanism 12 includes a lower support 121, a middle support 122, an upper support 123, and a rolling ball joint 124; the middle support 122 is located at the center of the lower support 121, and the middle support 122 and the upper support 123 are movably connected by the rolling ball joint 124 (to achieve rolling).

[0060] The upper support 123 is connected to the rolling ball joint 124, allowing the upper support 123 to roll relative to the lower support 121. A pallet support plate 118 is mounted on the upper support 123, and the pallet support plate 118 is connected to the pallet body 111 via a transverse spring assembly. The transverse spring assembly allows the pallet body 111 to move relative to the upper support 123 along the Y-axis direction (achieving heading and automatic recovery).

[0061] There are two lateral spring assemblies, symmetrically arranged between the pallet support plate 118 and the pallet body 111 along the X-axis. The lateral spring assembly includes a yaw axis 119 arranged along the Y-axis, and two pallet moving seats 116 sleeved on the yaw axis 119. A pallet support block 117 is sleeved between the two pallet moving seats 116 on the yaw axis 119. Springs are sleeved on the yaw axis 119 located between the pallet moving seats 116 and the pallet support block 117 to achieve automatic reset after movement along the Y-axis (i.e., yaw movement). The pallet moving seats 116 are connected to the bottom of the pallet body 111, and the pallet support block 117 is connected to the top of the pallet support plate 118.

[0062] The usage method of this embodiment is as follows:

[0063] When installing the wing, the wing is placed on the surface of the tray 11 of the support assembly 1. The support assemblies 1 at both ends support the root and tail of the wing respectively, forming two support points.

[0064] Push the two support components 1 to the designated installation position and lock the caster wheel 141.

[0065] Using handwheel 134 or other power tools, rotate the lifting mechanism input shaft 135 on the two support components 1 to lift the wing to the appropriate position and align it with the wing installation position for installation.

[0066] To facilitate adjustment of the wing mounting angle, the tilt angle of the tray 11 can be adjusted via the floating mechanism 12, and finally the wing mounting angle can be finely adjusted and locked via the attitude adjustment screw 113. The installation process can be carried out by finely adjusting the angle according to the actual situation.

[0067] The above description is merely one embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
