[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention. This embodiment provides a drone with foldable and retractable arms, including a protective component. The protective component includes a drone host 10. A rotary control motor 11 is fixedly connected to the outer wall of the drone host 10. An arm assembly 12 is movably connected to the outer wall of the drone host 10 through a rotating shaft. A cover assembly 13 is rotatably connected to the inner wall of the drone host 10. A storage compartment 14 is opened on the inner wall of the drone host 10.

[0017] The arm assembly 12 includes a main arm 121 rotatably connected to the outer wall of the UAV main body 10. One end of the main arm 121 is fixedly connected to a curved support arm 122. An extension pressure rod 123 is fixedly connected to the outer wall of the curved support arm 122. One end of the curved support arm 122 is fixedly connected to a wing 124.

[0018] The main arm 121 and the drone main unit 10 are movably connected by a rotating shaft. The output shaft of the rotary motor 11 is fixedly connected to a transmission rod through a coupling. One end of the transmission rod is fixedly connected to one end of the rotating shaft connected to the inner wall of the main arm 121.

[0019] The cover assembly 13 includes a long slide bar 135 that is rotatably connected to the inner wall of the drone host 10 and a first compression spring 133 that is fixedly connected to the inner wall of the drone host 10. One end of the first compression spring 133 is fixedly connected to a first pressure block 131. The outer wall of the first pressure block 131 is fitted with a second pressure block 132. One end of the second pressure block 132 is fixedly connected to a second compression spring 134. One end of the second compression spring 134 is fixedly connected to a connecting block. The outer wall of the connecting block is fixedly connected to the inner wall of the drone host 10. The outer wall of the long slide bar 135 is fixedly connected to a cover plate 136. One end of the long slide bar 135 is fixedly connected to the outer wall of the second pressure block 132.

[0020] When the drone is finished using it, the rotary motor 11 starts, driving the arm assembly 12 to rotate and fold. During the folding process, the main arm 121 presses against the first pressure block 131 of the compartment cover assembly 13. The first pressure block 131 slides and compresses the first compression spring 133, while simultaneously pressing the second pressure block 132. The second pressure block 132 drives the long slide bar 135 and the cover plate 136 to move, automatically opening the storage compartment 14. Subsequently, the curved support arm 122 and the wing 124 of the arm assembly 12 enter the storage compartment 14, so that the wing 124 is completely stored in the protective compartment, preventing the wing 124 from being exposed to the external environment after folding. This design prevents the wing 124 from being damaged or contaminated by collision, friction, dust or moisture during carrying and transportation, extending the service life of the wing 124.

[0021] It should be noted that the storage compartment 14 is automatically closed when the arm assembly 12 is deployed by the elastic reset of the first compression spring 133 and the second compression spring 134, forming a sealed protection and further enhancing the protective performance.

[0022] During use, after the drone is finished, the rotary control motor 11 is activated. The output shaft of the rotary control motor 11, through a transmission rod fixedly connected by a coupling, drives the rotating shaft on the inner wall of the main arm 121 to rotate, causing the arm assembly 12 to begin folding and retracting. The arm assembly 12 includes the main arm 121, the curved support arm 122, the extension pressure rod 123, and the wing 124. During the folding process, the main arm 121 first presses against the first pressure block 131 of the compartment cover assembly 13. The first pressure block 131 slides into the drone main body 10, compressing the first compression spring 133. At the same time, the outer wall of the first pressure block 131 presses against the second pressure block 132, causing the second pressure block 132 to slide towards the second compression spring 134, compressing the second compression spring 134. The second pressure block 132 drives the long slide bar 135 and the cover plate 136 to move, thereby opening the compartment cover of the storage compartment 14.

[0023] Example 2 Reference Figure 5-6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a drone with foldable and retractable arms, and also includes a locking component. The locking component includes a pressure contact component 20 that is slidably connected to the inner wall of the drone host 10. A locking component 21 is attached to the upper end of the pressure contact component 20, and a locking rod 22 is fixedly connected to the outer wall of the locking component 21. The pressure contact assembly 20 includes a pressure contact rod 201, a slide rod 203 is fixedly connected to the outer wall of the pressure contact rod 201, and a support slider 204 is fixedly connected to the upper outer wall of the slide rod 203. One end of the pressure rod 201 is fixedly connected to a return spring 202, and one end of the return spring 202 is fixedly connected to the inner wall of the drone host 10. The locking assembly 21 includes an upper contact pressure plate 211, a connecting pin 212 is fixedly connected to the upper end of the upper contact pressure plate 211, a connecting block 213 is movably connected to the upper outer wall of the upper contact pressure plate 211 through the connecting pin 212, and a locking spring 214 is fixedly connected to the upper outer wall of the connecting block 213. The top of the support slider 204 is provided with an upper inclined sliding surface, and the lower side of the upper contact pressure plate 211 is provided with a lower inclined sliding surface. The support slider 204 and the upper contact pressure plate 211 are slidably connected by the upper and lower inclined sliding surfaces. The locking rod 22 is fixedly connected to the upper contact pressure plate 211.

[0024] Specifically, the setting of the connecting pin 212 allows the locking lever 22 to be rotated within a small range, so that the locking lever 22 and the wing 124 can be used in a better manner. During the folding process of the arm assembly 12, the main arm 121 and the extension pressure rod 123 press against the pressure rod 201 of the pressure contact assembly 20. The pressure rod 201 slides along the inside of the UAV main unit 10, compressing the return spring 202 and causing the support slider 204 to move backward. After the support slider 204 disengages from the support of the connecting block 213 of the locking assembly 21, the upper contact pressure plate 211 of the locking assembly 21 moves through the connecting pivot pin 212 under the pressure of the locking spring 214 and gravity, causing the locking rod 22 to fall and insert into the outer wall of the wing 124. This locking mechanism ensures that the wing 124 is firmly fixed in the storage compartment 14, preventing the wing 124 from shaking, deforming or falling off during transportation due to vibration, impact or accidental movement. In particular, it protects the connection between the wing 124 and the bend-type support arm 122, which is a critical stress point of the UAV and is easily damaged due to stress concentration. The coordinated operation of the locking and protective components provides double protection, significantly improving the overall stability and reliability of the drone.

[0025] During use, after the storage compartment 14 is opened, the arm assembly 12 continues to rotate, and the curved support arm 122 and wing 124 enter the storage compartment 14, thus folding the wing 124 back into place. Simultaneously, as the arm assembly 12 presses against the first pressure block 131 and opens the cover plate 136, the main arm 121 and the extension pressure rod 123 respectively press against the pressure rod 201 of the pressure assembly 20. The pressure rod 201 slides along the inside of the UAV main unit 10, compressing the return spring 202. The slide bar 203 and the support slider 204 on the pressure rod 201 then move backward, disengaging the support slider 204 from the support of the connecting block 213 of the locking assembly 21. When the support slider 204 no longer supports the connecting block 213, the locking assembly 21, under the pressure of the locking spring 214 and gravity, causes the locking rod 22 to fall. The locking rod 22 inserts into the upper outer wall of the wing 124, locking the wing 124 inside the storage compartment 14. After folding and locking, the drone can be carried or transported. When it is necessary to unfold the arm, the rotary control motor 11 is activated in reverse, the arm assembly 12 unfolds, the pressure contact assembly 20 and the locking assembly 21 reset under the action of the spring, the locking rod 22 rises, and the compartment cover assembly 13 closes automatically.

[0026] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
