[0027] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model:

[0028] To address the problems mentioned in the background art, this utility model provides a portable folding multi-purpose drone, including a control cabin 1, a body 2, multiple folding catapult arms 3, and a function cabin 4. The control cabin 1 and the function cabin 4 are detachably connected to both ends of the body 2, and the multiple folding catapult arms 3 are rotatably connected to the body 2. The body 2 includes an outer shell 21, a battery box 22, a functional compartment connecting part 23, and an arm connecting part 27. The outer shell 21 is provided with multiple arm holes 24 for the folding catapult arm 3 to rotate. The number of arm holes 24 is the same as the number of folding catapult arms 3. The arm connecting part 27, the battery box 22, and the functional compartment connecting part 23 are arranged sequentially from top to bottom inside the body 2. The arm connecting part 27, the battery box 22, and the functional compartment connecting part 23 are coaxially connected in sequence. The arm connecting part 27 includes a connecting seat shaft hole 273, the battery box 22 includes a battery seat shaft hole 222, and the functional compartment connecting part 23 includes a connecting part shaft hole 233. The connecting seat shaft hole 273, the battery seat shaft hole 222, and the connecting part shaft hole 233 are connected in sequence. The battery box 22 also includes a battery slot 221, in which a battery is placed; the functional compartment connection part 23 also includes a battery cover 231 and a fastener 232. The battery cover 231 can abut against one end of the battery slot 221, and the fastener 232 has multiple fasteners for detachable connection with the functional compartment 4; the arm connection part 27 also includes a lug 271, a battery hole 272, and a side hole 274. The lug 271 is used for detachable connection with the control compartment 1, the side hole 274 is used for detachable connection with the outer shell 21, and the battery hole 272 is used to accommodate the other end of the battery slot 221. The folding catapult arm 3 includes an arm rod 31. One end of the arm rod 31 is rotatably connected to the arm connection part 27 through the catapult assembly 5; the other end of the arm rod 31 is provided with a mounting plate 32, and one side of the mounting plate 32 is connected to a propeller 35 through a drive motor 34. One end of the battery box 22, which is connected to the functional compartment connection 23, is coaxially equipped with a rotary motor 25 that can lock or release the folding catapult arm 3. Specifically, the output end of the rotary motor 25 is equipped with a hook 26, and the end of the arm rod 31 away from the arm connection 27 is equipped with a handle 33 that can be engaged with the hook 26. The handle 33 is mounted on the mounting plate 32 and is on the opposite side of the drive motor 34. The hook 26 is equipped with the same number of U-shaped slots 261 as the folding catapult arm 3.

[0029] The ejection assembly 5 includes a rotating base 51, a fixed shaft 52, a torsion spring 53, a rotating shaft 54, and a limiting block 55. The limiting block 55 limits the maximum angle of rotation of the boom 31. The fixed shaft 52 passes through the rotating base 51 and also passes through one end of the boom 31. Two torsion springs 53 are respectively installed at both ends of the fixed shaft 52. The rotating shaft 54 ​​passes through the boom 31, and both ends of the rotating shaft 54 ​​are connected to the fixed shaft 52 through two torsion springs 53. Multiple rotating bases 51 are connected to the boom connecting part 27 and are evenly distributed around the shaft hole 273 of the connecting seat.

[0030] As shown in the embodiment, the drone includes a control cabin 1, a fuselage 2, four sets of folding catapult arms 3, and a function cabin 4. The control cabin 1 is a near-hemispherical compartment in the upper part of the drone fuselage, used to house flight control systems and modules such as the flight control module and AI recognition module. It is connected to the arm connection part 27 via easily detachable screws using mounting lugs 271. The fuselage 2 includes an outer shell 21, arm connection parts 27, a battery box 22, a function cabin connection part 23, and a rotary motor 25. The outer shell 21 is cylindrical with four arm holes 24 on its surface for the extension of the folding catapult arms 3. The upper part of the outer shell 21 is connected to the arm connection part 27 via side holes 274, thus enabling a detachable connection between the outer shell 21 and the control cabin 1. The lower part of the outer shell 21 is connected to the function cabin 4 via the function cabin connection part 23. The battery box 22 is also connected to the arm connection 27. Inside the battery box 22 are four battery slots 221, each containing a lithium battery. These lithium batteries power the control cabin 1, the folding catapult arm 3, and the functional components within the functional cabin 4. The output end of the rotary motor 25 is rotatably connected to a hook 26. The hook 26 has four U-shaped slots 261, which are used to secure the handle 33 at the outer end of the arm 31, keeping it in a retracted state. Simultaneously, the hook 26, driven by the rotary motor 25, is used to release the retracted arm 31. The folding catapult arm 3 includes an integrated arm 31, a mounting plate 32, a handle 33, a drive motor 34, and propellers 35. There are four sets of folding catapult arms 3 used to provide flight power for the UAV. Figure 4 As shown, the rotating base 51 of the catapult assembly 5 is mounted on the arm connecting part 27, providing a fulcrum for the rotation of the arm rod 31. The fixed shaft 52 passes through the rotating base 51 and one end of the arm rod 31, allowing the arm rod 31 to rotate relative to the rotating base 51. Two torsion springs 53 are sleeved on both ends of the fixed shaft 52, with one end of the torsion spring 53 fixed to the end of the rotating shaft 54 ​​and the other end fixed to the arm connecting part 27, forming a rotational force on the arm rod 31. The limiting block 55 is located on the outside of the rotating base 51 and on the arm connecting part 27, limiting the maximum rotation angle of the arm rod 31 to 90°. The rotating shaft 54 ​​passes through the arm rod 31, and its two ends are connected to the two ends of the fixed shaft 52 through two torsion springs 53. Four rotating bases 51 are circumferentially arranged around the shaft hole 273 of the connecting seat. The main body of the torsion spring 53 is wound around the fixed shaft 52, and the central axis of the torsion spring 53 coincides with the central axis of the fixed shaft 52. The torsion spring 53 is attached at both ends to the boom connection 27 and the rotating shaft 54. When the boom 31 is in the folded state, the torsion spring 53 applies a clockwise torque to the rotating shaft 54, causing it to tend to rotate clockwise along the fixed shaft 52. When the hook 26 rotates to release the boom 31, the boom 31 rotates clockwise until it contacts the limit block 55, at which point the boom 31 remains perpendicular to the axis of the machine body 2.

[0031] Functional compartment 4 is a near-cylindrical compartment near the lower part of the UAV fuselage, used to house cameras, sensors, and various functional components such as explosives (for combat), loudspeakers (for communication and announcements), and storage compartments (for transporting emergency supplies). Functional compartment 4 is connected to the fastener 232 of functional compartment connection part 23 by easy-to-remove screws.

[0032] When the portable folding multi-purpose drone is in its retracted or ready-to-use state, the rotary motor 25 secures the arm 31, significantly reducing the overall volume and maintaining a near-cylindrical shape. When the drone is ready for deployment, the rotary motor 25 receives a remote control signal, causing the hook 26 to rotate at a certain angle. The handle 33 of the arm 31 disengages from the U-shaped slot 261. Due to the force exerted on the arm 31 by the ejection assembly 5, the arm 31 unfolds. Under the action of the two torsion springs 53, the arm 31 quickly unfolds into its working posture, changing from a parallel state to a perpendicular state to the body 2. At this point, the folding drone can take off immediately. Depending on the types of functional components mounted in the functional compartment 4, the folding drone can perform different tasks. When a task is completed, the propellers 35 are manually folded, and the four arms 31 are folded back into the body 2. The rotary motor 25 receives a remote control signal, and the hook 26 rotates, locking the handle 33 into the U-shaped slot 261, thus locking the folding ejection arm 3. When replacing the battery, simply remove the functional compartment 4 and the functional compartment connector 23, and then reinstall the functional compartment connector 23 and the functional compartment 4 after replacing the battery.

[0033] Portable folding multi-purpose drones solve the problems of traditional rotary-wing drones being inconvenient to carry, as well as the shortcomings of existing folding drones, such as limited functionality, high cost, and difficulty in controlling the retraction and extension of the folding arms. The folding structure makes it easy to carry and transport, and also facilitates operation in various terrains and spaces where traditional rotary-wing drones are difficult to operate in; the multiple functional compartments that can be carried on the folding drone enable it to achieve a variety of operational functions; the retraction and extension of the arms can be controlled by a fixed motor.

[0034] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
