Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a two-in-one convertible UAV. Background Art

[0002] Existing aircraft can be categorized into helicopters and fixed-wing aircraft based on their flight principles. The former includes multi-rotor helicopters, coaxial rotor helicopters, and cross-rotor helicopters, while the latter includes tiltrotor aircraft, vertical takeoff and landing (VTOL) compound-wing aircraft, and tail-seat VTOL aircraft. These two types of aircraft fly in distinct ways. Unmanned aerial vehicles (UAVs) are also generally classified into these two types. Helicopter-type UAVs can take off and land vertically and hover, but they rely entirely on their rotors for lift, resulting in high energy consumption and short endurance. Fixed-wing UAVs have high flight speeds and relatively low energy consumption, but they cannot hover (compound-wing aircraft) or can only hover briefly (tilt-rotor / compound-wing models). Furthermore, due to their large size, fixed-wing models have poor wind resistance.

[0003] As drones face increasingly diverse flight scenarios, some scenarios, such as logistics, emergency rescue, and security management, sometimes require hovering in helicopter mode to obtain better imagery and detailed on-site information or precise material delivery, while other times they require flying in fixed-wing aircraft mode to reach farther target areas or fly for longer periods to continuously acquire on-site images. This necessitates configuring both helicopters and fixed-wing aircraft to address the different needs of the same scenario, which is costly, space-consuming, and inconvenient for deployment and portability. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems and provide a two-in-one convertible drone. By changing the orientation of the wing mounting part and in conjunction with the detachment and assembly of the fixed wing, the drone can switch between helicopter mode and fixed-wing mode on the same drone. This eliminates the need to carry two different types of drones, reduces equipment costs and space occupancy, and facilitates deployment and portability.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] This embodiment provides a two-in-one convertible drone, such as Figures 1 to 19 As shown, the system includes a fuselage 1 and a fixed wing 2. Wing mounting sections are located on both sides of the fuselage 1. Each wing mounting section has a fixed wing connector and two rotor rods 501, on which rotors 5 are mounted. The two rotor rods 501 are arranged in a V-shape, and the coplanarity of the rotors 5 on the two rotor rods 501 is parallel to the coplanarity of the two rotor rods 501. The fixed wing connector is used for the detachable installation of the fixed wing 2. The fixed wing connector is located between the two rotor rods 501, and the wing surface of the fixed wing 2 mounted on the fixed wing connector is perpendicular to the coplanarity of the two rotor rods 501. The orientation of the wing mounting sections can be changed, and the coplanarity of the two rotor rods 501 can be perpendicular to or parallel to the length direction of the fuselage 1 along the path of the orientation change, thus forming both fixed-wing and helicopter modes.

[0047] Helicopter mode: such as Figure 1 and Figure 12 As shown, this is the first form of orientation change for the wing mounting section. When the coplanarity of the two rotor rods 501 is parallel to the length direction of the fuselage 1, the rotors 5 on the two rotor rods 501 are set horizontally upward (towards the top of the fuselage) and can generate upward lift. If the fixed wing 2 is not installed or is removed, the UAV is in helicopter mode and can have the flight characteristics of a helicopter UAV, including vertical take-off and landing and long-term hovering.

[0048] Fixed-wing mode: such as Figure 2, Figure 3 and Figure 6 As shown, this is the second orientation change form of the wing mounting part. When the coplanarity of the two rotor rods 501 is perpendicular to the length direction of the fuselage 1, the rotors 5 on the two rotor rods 501 are set vertically forward (nose direction) and can generate a rearward (tail direction) thrust. The fixed wing 2 is installed on the fixed wing connection part. At this time, the UAV is in fixed wing mode and can have the flight characteristics of a fixed wing and rotor hybrid UAV, with high flight speed, relatively low energy consumption, and high wind resistance.

[0049] By changing the orientation of the wing mounting section according to different needs, and in conjunction with the disassembly and assembly of the fixed wing 2, two modes can be switched on the same drone, eliminating the need to carry two different types of drones, reducing equipment costs and space occupancy, and making deployment and carrying convenient.

[0050] In this embodiment, as Figures 1 to 19 As shown, the wing mounting portion is a circular mounting base 3. The rotor rod 501 and the fixed wing connection portion are located on the circular surface of the circular mounting base 3. The circumference of the circular mounting base 3 is provided with circular mounting base A screw hole 302 and circular mounting base B screw hole 303. The line connecting the circular mounting base A screw hole 302 to the center of the circular mounting base 3 is perpendicular to the coplanarity of the two rotor rods 501, and the circular mounting base A screw hole 302 is located on the rear side facing the rotor 5. The line connecting the circular mounting base B screw hole 303 to the center of the circular mounting base 3 is located on the coplanarity of the two rotor rods 501. Circular mounting grooves 101 are provided on both sides of the fuselage 1, and the circular mounting grooves 101 match the circular mounting base 3 for mounting the circular mounting base 3. The side wall of the circular mounting groove 101 is provided with a circular mounting groove screw hole 102, which penetrates the bottom of the body 1. The line connecting the center of the circular mounting groove 102 and the circular mounting groove 101 is perpendicular to the length direction of the body 1.

[0051] Installation principle: After inserting the circular mounting base 3 into the circular mounting slot 101, if the screw holes 302 of the circular mounting base A and 102 of the circular mounting slot are aligned and the screws are screwed in, the coplanar plane of the two rotor rods 501 will be parallel to the length direction of the fuselage 1. (Refer to...) Figure 1 Without installing or removing the fixed wing 2, the drone is in helicopter mode. However, if the screw holes 303 and 102 of the circular mounting bracket B are aligned and the screws are screwed in, the coplanarity of the two rotor rods 501 will be perpendicular to the length direction of the fuselage 1. (Refer to...) Figure 6 Attach the fixed-wing 2 module; the drone will then be in fixed-wing mode. (Refer to...) Figure 2 and Figure 3 .

[0052] In this embodiment, as Figures 1 to 19As shown, the fixed wing connection is a rectangular slot 304 mounted on a circular mounting base 3. The rectangular slot 304 is located between the two rotor rods 501, and its length is perpendicular to the coplanarity of the two rotor rods 501. A circular mounting base B screw hole 303 is located at one end of the rectangular slot 304, and a circular mounting base C screw hole 305 is located at the other end of the rectangular slot 304. A rectangular plug 201 is located at the base of the fixed wing 2, which matches the rectangular slot 304 for insertion. The rectangular plug 201 has a wing mounting screw hole 202. By aligning the wing mounting screw hole 202 of the rectangular plug 201 with the screw hole 305 of the circular mounting base C, and then inserting the rectangular plug 201 into the rectangular slot 304, the wing mounting screw hole 202 will align with the screw hole 305 of the circular mounting base C. Tightening the screw completes the installation of the fixed wing 2 and the circular mounting base 3.

[0053] To check whether the circular mounting base 3 and the fixed wing 2 are properly installed, in this embodiment, as follows: Figures 1 to 19 As shown, a circular mounting base A contact 306 is provided on the circumference of the circular mounting base 3. A circular mounting groove A contact 103 and a circular mounting groove B contact 104 are provided within the circular mounting groove 101. The position of the circular mounting groove A contact 103 is such that when the screw holes 302 of the circular mounting base A and 102 of the circular mounting groove are aligned, the circular mounting base A contact 306 and the circular mounting groove A contact 103 are in contact and conductive, so that the UAV control system can detect the state of the rotor 5 later. Figure 19 As shown. The location of contact 104 in the circular mounting slot B needs to ensure that when screw holes 303 and 102 in the circular mounting base B are aligned, contact 306 in the circular mounting base A and contact 104 in the circular mounting slot B will be in contact and conducting. This is necessary for the UAV control system to detect the state of rotor 5 later. Figure 19 As shown.

[0054] A circular mounting base B contact 308 is provided within a rectangular slot 304. A wing detection contact 205 is provided on a rectangular plug 201. When the circular mounting base B contact 308 and the wing detection contact 205 are positioned such that the screw hole 305 of the circular mounting base C and the wing mounting screw hole 202 are aligned, the wing detection contact 205 and the circular mounting base B contact 308 make contact and conduction, allowing the UAV control system to detect whether a fixed wing is installed. Figure 19 As shown.

[0055] Furthermore, in this embodiment, as Figures 1 to 19As shown, the wing mounting portion can also be a rectangular mounting base 4. The rotor rod 501 is located on the front of the rectangular mounting base 4, and the width direction of the rectangular mounting base 4 is perpendicular to and coplanar with the two rotor rods 501. The area on the rectangular mounting base 4 between the two rotor rods 501 is the fixed wing connection portion. The side and bottom surfaces of the rectangular mounting base 4 are respectively provided with rectangular mounting base A screw hole 401 and rectangular mounting base B screw hole 402.

[0056] The fuselage 1 has vertical rectangular slots 105 and horizontal rectangular slots 106 on both sides, both of which match the rectangular mounting base 4. The length direction of the vertical rectangular slot 105 is perpendicular to the length direction of the fuselage 1, and the length direction of the horizontal rectangular slot 106 is in the same direction as the length direction of the fuselage 1. The vertical rectangular slot 105 and the horizontal rectangular slot 106 intersect, and the intersection area corresponds to the fixed wing connection part. The vertical rectangular slot 105 has a rectangular slot A screw hole 107, which matches the rectangular mounting base A screw hole 401 of the rectangular mounting base 4. The horizontal rectangular slot 106 has a rectangular slot B screw hole 108, which matches the rectangular mounting base B screw hole 402 of the rectangular mounting base 4. Both the rectangular slot A screw hole 107 and the rectangular slot B screw hole 108 penetrate through the bottom of the fuselage 1.

[0057] The fixed wing 2 has a rectangular plug 201 at its base, which matches both the vertical rectangular slot 105 and the horizontal rectangular slot 106. The rectangular plug 201 has a wing slot 204 for insertion into the fixed wing connector of the fixed wing 2. The rectangular plug 201 has wing mounting screw holes 202. With the wing mounting screw holes 202 of the rectangular plug 201 aligned with the screw holes 108 in the rectangular slot B, and the rectangular plug 201 inserted into the horizontal rectangular slot 106, the wing mounting screw holes 202 will align with the screw holes 108 in the rectangular slot B. Screwing in the screws completes the installation of the fixed wing 2 and the rectangular mounting base 4.

[0058] Installation Principle: If the rectangular mounting base 4 is inserted into the horizontal rectangular slot 106, align the screw holes 401 and 107 of the rectangular mounting base A and screw in, completing the installation of the rectangular mounting base 4. Without installing or removing the fixed wing 2, the rotor 5 faces horizontally upwards, and the drone is in helicopter mode. If the rectangular mounting base 4 is inserted into the vertical rectangular slot 105, align the screw holes 401 and 107 of the rectangular mounting base A and screw in, completing the installation of the rectangular mounting base 4, insert the wing slot 204 of the rectangular plug 201 into the fixed wing connection part of the fixed wing 2, and insert the rectangular plug 201 into the horizontal rectangular slot 106. In this case, the rotor 5 faces horizontally forward, the fixed wing 2 is horizontally positioned, and the drone is in fixed-wing mode.

[0059] Furthermore, in this embodiment, as Figures 1 to 19 As shown, the rectangular mounting base 4 is provided with a rectangular mounting base contact 403. A rectangular slot A contact 109 is provided within the vertical rectangular slot 105. The position of the rectangular slot A contact 109 is such that when the rectangular mounting base A screw hole 401 and the rectangular slot A screw hole 107 are aligned, the rectangular slot A contact 109 and the rectangular mounting base contact 403 are in contact and conductive, allowing the UAV control system to detect the state of the rotor 5 later. Figure 19 As shown. A rectangular slot B contact 110 is provided within the horizontal rectangular slot 106. When the rectangular mounting base B screw hole 402 and the rectangular slot B screw hole 108 are aligned, the rectangular slot B contact 110 and the rectangular mounting base contact 403 are in contact and conductive, allowing the UAV control system to detect the state of the rotor 5 later. Figure 19 As shown. The rectangular plug 201 has a wing detection contact 205. After the rectangular plug 201 is inserted into the horizontal rectangular slot 106, the wing detection contact 205 makes contact with the contact 110 of the rectangular slot B, allowing the UAV control system to detect whether the fixed wing 2 is installed. Figure 19 As shown.

[0060] In this embodiment, as Figures 1 to 19 As shown, the wing mounting section uses either a rectangular mounting base 4 or a circular mounting base 3. The rotor rod 501 and the wing mounting section are connected via a wing rod connecting tube 307. Specifically, the wing rod connecting tube 307 is pre-installed on the rectangular mounting base 4 or the circular mounting base 3. Then, the rotor rod 501 is inserted into the wing rod connecting tube 307 and fixed in place, thus completing the installation of the rotor rod 501. The fixing methods include, but are not limited to, welding, threaded connections, and screw connections.

[0061] In this embodiment, as Figures 1 to 19 As shown, a rotor motor 502 is located at the end of the rotor rod 501, and the rotor 5 is mounted on the rotor motor 502 to drive the rotor 5 to rotate. If the wing mounting part is a rectangular mounting base 4, a control line hole 404 is also provided, through which control cables and power cables are connected to the rotor motor 502. If the wing mounting part is a circular mounting base 3, a cable hole is also provided for connecting control cables and power cables to the rotor motor 502. Preferably, the rotor rod 501 is a hollow rod for carrying cables.

[0062] In this embodiment, as Figures 1 to 19 As shown, the fuselage 1 is streamlined in shape. If it is set to an ellipsoid, the two apexes of the ellipsoid are the nose and the tail, which can effectively reduce wind resistance.

[0063] Furthermore, in this embodiment, as Figures 1 to 19As shown, the fuselage 1 has flat areas 111 on both sides and at the bottom. The flat areas 111 on both sides are conducive to setting up circular mounting slots 101 or vertical rectangular slots 105 and horizontal rectangular slots 106. The flat area 111 at the bottom is conducive to installing structures such as landing gear.

[0064] In this embodiment, as Figures 1 to 19 As shown, the tail of the fuselage 1 is provided with a tail fin mounting head 112 for mounting the tail fin 6. If the fixed wing 2 is of the type with a folding fin 203 at the tip, then the tail fin 6 is not required. However, if the fixed wing 2 is of the type without a folding fin 203 at the tip, then the tail fin 6 is required.

[0065] Furthermore, in this embodiment, as Figures 1 to 19 As shown, the tail wing mounting head 112 is a tubular structure, and the tail wing 6 is provided with a tail wing plug 601 for insertion into the tail wing mounting head 112. The inner wall of the tail wing mounting head 112 has a positioning protrusion 113, and the tail wing plug 601 has a positioning groove 602. Through the cooperation of the positioning groove 602 and the positioning protrusion 113, the tail wing plug 601 can be guided into the tail wing mounting head 112, ensuring that the tail wing plug 601 can only move along the axial direction of the tail wing mounting head 112 and will not rotate. After the tail wing plug 601 is inserted into the tail wing mounting head 112, it can be fixed by screws, i.e., corresponding screw holes are drilled on the tail wing plug 601 and the tail wing mounting head 112. The tail fin mounting head 112 has a mounting head contact 114, and the tail fin plug 601 has a tail fin contact 603. When the screw holes of the tail fin plug 601 and the tail fin mounting head 112 are aligned, the mounting head contact 114 and the tail fin contact 603 make contact and conduct electricity, so that the UAV control system can detect whether the tail fin 6 is installed later. Figure 19 As shown.

[0066] In this embodiment, as Figures 1 to 19 As shown, this UAV is equipped with a UAV control system, which works in conjunction with various circuit contacts for detecting modes and states. Based on the detected information, it executes control logic algorithms adapted to the UAV model. UAV control system flow:

[0067] After the drone control system is powered on, it first checks whether rotor 5 is horizontally mounted. If horizontally mounted, the drone is controlled using the multi-rotor drone logic algorithm. If not horizontally mounted, it checks whether the rotor is vertically mounted. If not vertically mounted, an abnormal warning is issued. If vertically mounted, it checks whether fixed wing 2 is installed. If not installed, an abnormal warning is issued. If fixed wing 2 is installed, it checks whether tail fin 6 is installed. If tail fin 6 is not installed, the drone is controlled using the tailless fixed-wing drone logic algorithm. If tail fin 6 is installed, the drone is controlled using the tail-equipped fixed-wing drone logic algorithm.

[0068] Specifically, the rotor status detection information circuit connection is as follows: Figure 17 As shown, the information is sent via the I interface, passing through the circular mounting base A contact 306. If the circular mounting base A contact 306 is connected to the circular mounting slot A contact 103, the A interface receives the information, indicating that the rotor 5 is horizontally installed. If the circular mounting base A contact 306 is connected to the circular mounting slot B contact 104, the B interface receives the information. If the information is received at the B interface, it indicates that the rotor 5 is vertically installed. If a rectangular mounting base 4 is used, if the rectangular mounting base contact 403 is connected to the rectangular slot B contact 110, the A interface receives the information, indicating that the rotor 5 is horizontally installed. If the rectangular mounting base contact 403 is connected to the rectangular slot A contact 109, the B interface receives the information. If the information is received at the B interface, it indicates that the rotor 5 is vertically installed.

[0069] Tail wing 6 detection connection as follows Figure 18 The information is sent by the T interface. If the mounting head contact 114 is connected to the tail fin contact 603, the R interface receives the information. If the signal is on, it means that the tail fin 6 has been installed; if it is not on, it means that it has not been installed.

[0070] Fixed-wing aircraft 2 can be referenced. Figure 18 The settings are configured, and the information is sent via the T interface. If the rectangular slot B contact 110 is connected to the wing detection contact 205, the R interface receives the information. A signal conduction indicates that the fixed wing 2 has been installed, while no conduction indicates that it has not been installed.
