[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution:

[0021] A reinforcement structure for the lower wing panel of a drone includes: a body 1, wings 2 fixedly mounted on both sides of the body 1, mounting plates 3 on the lower wing panel and the side wall of the body 1, a reinforcing rib 4 fixedly connected between the two mounting plates 3, a sliding groove 5 on one side of the wing 2, an auxiliary wing 6 slidably mounted in the sliding groove 5, and an adjustment component 7 on the wing 2 to extend and retract the sliding groove 5. By installing the reinforcing rib 4 between the lower wing panel and the body 1, the stability of the wing 2 can be improved.

[0022] In this embodiment: the adjustment assembly 7 includes a lead screw 701, which is rotatably installed in the slide groove 5. A threaded groove 702 is provided on one side of the auxiliary wing 6, which is threadedly connected to the lead screw 701. A groove 703 is provided on one side of the top of the wing 2. One side of the lead screw 701 passes through the groove 703 and is connected to the output end of the drive motor 704. The drive motor 704 drives the lead screw 701 to rotate. Through the transmission of the lead screw 701 and the threaded groove 702, the auxiliary wing 6 can slide in the slide groove 5.

[0023] In this embodiment: a guide rod 705 is installed in the slide groove 5, and a sliding hole 706 is opened on one side of the auxiliary wing 6 to be slidably connected with the guide rod 705. The auxiliary wing 6 slides in the slide groove 5, and the guide rod 705 slides in the sliding hole 706, which plays a limiting role for the auxiliary wing 6.

[0024] In this embodiment: The top of the groove 703 is provided with a cover plate 707, which can protect the drive motor 704 and reduce the dust accumulation on the drive motor 704.

[0025] In this embodiment: the cover plate 707 and the wing 2 are detachably installed by bolts 708. The detachability of the cover plate 707 and the wing 2 facilitates the maintenance of the drive motor 704.

[0026] In this embodiment: the material of the reinforcing rib 4 is carbon fiber reinforced polymer matrix composite material, which has the advantages of being lightweight and having high strength.

[0027] The workflow of this embodiment is as follows: The stability between the body 1 and the wing 2 can be improved by the reinforcing rib 4. When the UAV is not in use in the hangar, the drive motor 704 can be started to rotate the lead screw 701. The lead screw 701, through the transmission with the threaded groove 702, causes the auxiliary wing 6 to retract into the slide groove 5, reducing the overall width and making it easier to store in the hangar.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
