Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a spherical UAV that is convenient to carry and transport. Background Art

[0002] Drones are unmanned aircraft controlled by radio remote control and self-contained programmable controls, or operated fully or intermittently autonomously by an onboard computer. Compared to manned aircraft, drones are often better suited for missions deemed too "dull, dirty, or dangerous." Drones can be categorized into military and civilian applications. In the military, drones are divided into reconnaissance and target drones. In the civilian sector, drone integration into industrial applications is a real necessity. Applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television production, and creating romance have greatly expanded the uses of drones. Developed countries are also actively expanding industrial applications and developing drone technology.

[0003] As is known, existing drones generally consist of a fuselage and wings mounted on the fuselage. During use, most drones need to be carried because they are often used outdoors. However, drones are generally large in size and inconvenient to carry. In addition, in order to prevent the wings from being squeezed and damaged during carrying, the wings are generally disassembled and separated from the fuselage for unloading, which makes the drone take up a large space during carrying and is more troublesome. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a spherical drone that is easy to carry and transport.

[0005] The present invention adopts the following technical solution: a spherical drone that is easy to carry and transport, comprising a base, a leg assembly disposed below the base, a cylindrical seat welded to the upper surface of the base, a fuselage disposed above the cylindrical seat, and a spherical outer cover assembly disposed around the outer periphery of the cylindrical seat;

[0006] The spherical outer cover assembly includes a strip seat, one end of the strip seat is welded to the cylindrical seat, and the other end of the strip seat is embedded with a welded arc frame, and there are four arc frames in total, and the four arc frames are distributed in a circular shape with equal intervals around the outer side of the cylindrical seat, a cross bar is welded between two adjacent arc frames, and a sleeve is provided on the cross bar, a connecting frame is welded on the outer wall of the sleeve, and an arc cover is welded and fixed to the connecting frame, and there are four arc covers in total, and the four arc covers are distributed in a circular shape, and a driving mechanism is provided on the base, and the driving mechanism is used to drive the four arc covers to rotate circumferentially along the cross bar and close to each other to form a closed spherical structure.

[0007] As a further description of the above technical solution: the driving mechanism includes a driven gear and a driving motor, the driven gear is welded and fixed at the center of the sleeve, the driving motor is bolted to the base, the driving gear is fixed to the output shaft of the driving motor, and the driving gear is meshed with the driven gear.

[0008] As a further description of the above technical solution: an electric telescopic rod is installed at the center of the upper surface of the fuselage, and the top end of the electric telescopic rod is threadedly connected to a card seat.

[0009] As a further description of the above technical solution: the leg assembly includes a concave frame and a polygonal column, the polygonal column is welded and fixed at the center of the lower surface of the base, and several concave frames are welded around the lower surface of the base located on the outside of the polygonal column. The concave frame is rotatably connected to the support leg through a rotating shaft, and a spring is welded between the support leg and the outer wall of the polygonal column.

[0010] As a further description of the above technical solution: there are a plurality of legs provided, and the legs are distributed in a ring shape, the distance between two adjacent legs is equal, and the legs are a V-shaped structure.

[0011] As a further description of the above technical solution: the body consists of a shell and a battery, a controller and a wireless connector installed in the shell. The controller is wirelessly connected to the terminal PC through the wireless connector. A charging hole is opened on the lower surface of the shell, and the charging hole is used to charge the battery.

[0012] As a further description of the above technical solution: a servo motor is installed at the center of the inner wall of the arc-shaped cover, and wings are installed on the output shaft of the servo motor. There are four groups of wings in total, and the four groups of wings are distributed in a circular shape with equal intervals around the outside of the fuselage.

[0013] In the above technical solution, the present invention provides a spherical drone that is easy to carry and transport. When not in use, the driving mechanism drives the sleeve to rotate in the opposite direction on the cross bar again, and the sleeve drives the arc cover to rotate in the opposite direction upward through the connecting frame, thereby driving the four arc covers to close each other to form a closed spherical structure. At this time, the servo motor and wings arranged in the arc cover are all located in the closed spherical structure to protect the wings, so that the drone will not collide with the wings and fuselage during transportation, thereby improving its stability during transportation. It also overcomes the problem that the existing drones need to disassemble the wings to prevent the wings from being squeezed and damaged during transportation, and then place the fuselage and wings separately in a transport box, which makes it difficult to carry and transport, and needs to be assembled again when used.

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific diagrams. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless they conflict.

[0024] See also Figure 1-Figure 7 The embodiment of the present invention provides a technical solution: a spherical drone that is easy to carry and transport, comprising a base 1, a leg assembly 2 is arranged below the base 1, a cylindrical seat 11 is welded to the upper surface of the base 1, a fuselage 5 is arranged above the cylindrical seat 11, and a spherical outer cover assembly 3 is arranged around the outer side of the cylindrical seat 11;

[0025] The spherical outer cover assembly 3 includes a strip seat 31, one end of the strip seat 31 is welded to the cylindrical seat 11, and the other end of the strip seat 31 is embedded with a curved frame 32. There are four curved frames 32, and the four curved frames 32 are distributed in a circular shape with equal spacing around the outer side of the cylindrical seat 11. A cross bar 33 is welded between two adjacent curved frames 32, and a sleeve 34 is sleeved on the cross bar 33. A connecting frame 36 is welded to the outer wall of the sleeve 34, and a curved cover 39 is welded and fixed to the connecting frame 36. There are four arc-shaped covers 39 in total, and the four arc-shaped covers 39 are distributed in a ring shape. A driving mechanism is provided on the base 1, and the driving mechanism is used to drive the four arc-shaped covers 39 to rotate circumferentially along the cross bar 33 and close to each other to form a closed spherical structure. A servo motor 310 is installed at the center of the inner wall of the arc-shaped cover 39, and wings 311 are installed on the output shaft of the servo motor 310. There are four groups of wings 311 in total, and the four groups of wings 311 are distributed in a ring shape with equal intervals around the outer side of the fuselage 5.

[0026] Specifically, when the spherical drone that is easy to carry and transport is in use, the driving mechanism is controlled to drive the sleeve 34 to rotate on the crossbar 33, and the sleeve 34 drives the arc cover 39 to rotate through the connecting frame 36, so that the arc covers 39 are rotated to a horizontal state (such as Figure 2 ), at this time, the wings 311 set on the arc cover 39 are in a horizontal state, and the spherical drone can be used. When not in use, the driving mechanism drives the sleeve 34 to rotate in the opposite direction on the cross bar 33 again, and the sleeve 34 drives the arc cover 39 to rotate upward in the opposite direction through the connecting frame 36, thereby driving the four arc covers 39 to close each other to form a closed spherical structure (such as Figure 1 ), at this time, the servo motor 310 and the wing 311 provided in the arc cover 39 are both located in the closed spherical structure, protecting the wing 311, so that the UAV will not collide with the wing 311 and the fuselage 5 when being carried and transported, thereby improving its stability in carrying and transportation, and overcoming the problem that in the existing UAV, in order to prevent the wing 311 from being squeezed and damaged during transportation, the wing 311 needs to be disassembled, and then the fuselage 5 and the wing 311 need to be separately placed in a transport box, which makes it difficult to carry and transport, and needs to be assembled again when used.

[0027] In another embodiment provided by the present invention, the driving mechanism includes a driven gear 35 and a driving motor 37. The driven gear 35 is welded and fixed at the center of the sleeve 34. The driving motor 37 is bolted to the base 1. A driving gear 38 is fixed to the output shaft of the driving motor 37. The driving gear 38 is meshed and connected with the driven gear 35.

[0028] Specifically, based on the above embodiment, when the arc cover 39 is controlled to rotate by the driving mechanism, the specific driving method of the driving mechanism is to control the driving motor 37 to work, the driving motor 37 drives the driving gear 38 to rotate, and the driving gear 38 drives the sleeve 34 to rotate through the driven gear 35, so that the sleeve 34 drives the arc cover 39 to rotate through the connecting frame 36.

[0029] In another embodiment provided by the present invention, an electric telescopic rod 6 is installed at the center of the upper surface of the fuselage 5, and a clamping seat 7 is threadedly connected to the top end of the electric telescopic rod 6.

[0030] Specifically, based on the above embodiment, when the four curved covers 39 are controlled by the driving mechanism to rotate circumferentially along the crossbar 33 and move closer to each other to form a closed spherical structure, the electric telescopic rod 6 is controlled to extend and retract, driving the clamping seat 7 to move downward and clamp onto the top ends of the four curved covers 39, providing auxiliary support and position limiting for the curved covers 39, thereby improving the stability of the closed spherical structure formed by the curved covers 39. When it is necessary to control the curved covers 39 to rotate outward and open, it is first necessary to control the electric telescopic rod 6 to extend, driving the clamping seat 7 to move upward and separate from the curved covers 39. This ensures that the clamping seat 7 does not affect the rotation and opening of the curved covers 39.

[0031] In another embodiment provided by the present invention, the leg assembly 2 includes a concave frame 21 and a polygonal column 24. The polygonal column 24 is welded and fixed at the center of the lower surface of the base 1. Several concave frames 21 are welded around the outer side of the polygonal column 24 on the lower surface of the base 1. The concave frame 21 is rotatably connected with a support leg 23 through a rotating shaft 22. A spring 25 is welded between the support leg 23 and the outer wall of the polygonal column 24. There are several support legs 23 in total, and the several support legs 23 are distributed in a ring shape. The distance between two adjacent support legs 23 is equal, and the support legs 23 are a V-shaped structure.

[0032] Specifically, based on the above embodiment, the leg assembly 2 is provided to support the base 1. During use, when the drone lands, the legs 23 contact the ground, and the legs 23 are rotatably connected to the concave frame 21 through the rotating shaft 22. The legs 23 are welded and fixed to the polygonal column 24 through the spring 25. The elastic buffering of the spring 25 drives the legs 23 to rotate, which can reduce the vibration of the drone during landing and improve its stability during landing.

[0033] In another embodiment provided by the present invention, the body 5 is composed of a shell 51 and a battery 52, a controller 53 and a wireless connector 54 installed in the shell 51. The controller 53 is wirelessly connected to the terminal PC through the wireless connector 54.
