[0037] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0038] Please refer to Figures 1 to 4 , the embodiment of the present application provides an unmanned aerial vehicle 100, which is applied to an unmanned aerial vehicle system. Among them, the unmanned aerial vehicle system further includes an unmanned aerial vehicle remote control device, and the unmanned aerial vehicle remote control device can be communicatively connected to the unmanned aerial vehicle 100 during use to remotely control the unmanned aerial vehicle 100 and perform data transmission.

[0039] In some embodiments, the drone 100 includes a main body 10, a first rotor module 20, and a flipping assembly 30. The first rotor module 20 is fixedly connected to the main body 10. The flipping assembly 30 includes a second rotor module 31 and a flipping module 32. The flipping module 32 is respectively connected to the main body 10 and the second rotor module 31. The flipping module 32 can drive the second rotor module 31 to flip relative to the main body 10 around a flipping axis. The flipping module 32 is configured to cause the first rotor module 20 and the second rotor module 31 to overlap each other when flipped to a first flipping angle, and to cause the first rotor module 20 and the second rotor module 31 to be respectively located on opposite sides of the main body 10 when flipped to a second flipping angle. The flipping module 32 can be locked when flipped to the second flipping angle to lock the second rotor module 31.

[0040] The structural principle of the drone 100 according to the embodiments of the present application is as follows: The main body 10 is the core component of the drone 100, and a control circuit, a battery, sensors, a communication module, etc. are installed thereon. The first rotor module 20 and the second rotor module 31 are controlled by the main body 10 and provide lift for the entire drone 100, enabling the drone 100 to hover or fly in the air. Among them, the first rotor module 20 is fixedly connected to the main body 10, while the second rotor module 31 and the flipping module 32 together form a part of the flipping assembly 30. Specifically, the second rotor module 31 follows the flipping assembly 30 to flip. When the flipping assembly 30 is flipped to the first flipping angle, the second rotor module 31 overlaps with the first rotor module 20, thereby reducing the storage size of the drone 100; when the flipping assembly 30 is flipped to the second flipping angle, the second rotor module 31 can be locked following the flipping assembly 30 and is respectively located on opposite sides of the main body 10, so as to facilitate the balance of lift when the drone 100 hovers and flies.

[0041] It can be understood that the drone 100 according to the embodiments of the present application can drive the second rotor module 31 to flip through the flipping module 32, and can cause the first rotor module 20 and the second rotor module 31 to overlap each other during storage to reduce the volume of the drone 100. Further, since the first rotor module 20 and the second rotor module 31 account for a relatively large proportion of the volume of the entire drone 100, the storage size can be significantly reduced after overlapping, which means that the embodiments of the present application can achieve a significant reduction in the storage size of the entire drone 100 through a single flipping action and can be used after a single deployment, thereby reducing the learning cost and operation difficulty of the user.

[0042] In some embodiments, any one of the first rotor module 20 and the second rotor module 31 includes a rotor bracket and at least one rotor unit. The rotor unit is installed on the rotor bracket, and the rotor unit is a lift unit in the rotor module and is composed of at least one set of rotors and motors.

[0043] In some embodiments, when the first rotor module 20 and the second rotor module 31 are superposed, their projections on the superposition plane overlap and align with each other. The superposition plane referred to in the embodiments of the present application is the contact plane between the first rotor module 20 and the second rotor module 31 or the symmetry plane between the two. Specifically, in order to further reduce the storage size of the drone 100, the first rotor module 20 and the second rotor module 31 have the same structural dimensions, and their outer contours can align with each other when they are superposed. Exemplarily, there is a 180° interval between the first flipping angle and the second flipping angle. When the first rotor module 20 and the second rotor module 31 are superposed, it is the initial state. When the flipping module 32 drives the second rotor module 31 to flip 180° from the initial state, it is in the fully deployed state, so that the deployed second rotor module 31 and the first rotor module 20 are on the same horizontal plane.

[0044] Please review Figure 1 In some embodiments, the flipping axis is parallel to the length direction of the main body 10, and the main body 10 includes at least two flipping cooperation structures 11 spaced apart in the length direction. The flipping module 32 includes at least two flipping units 321. Each flipping unit 321 is connected to the second rotor module 31, and each flipping unit 321 is connected to a corresponding flipping cooperation structure 11. The flipping unit 321 is used to cooperate with the flipping cooperation structure 11 to drive the second rotor module 31 to flip relative to the main body 10 around the flipping axis, and to superpose the first rotor module 20 and the second rotor module 31 when the second rotor module 31 flips to the first flipping angle, and to place the first rotor module 20 and the second rotor module 31 on opposite sides of the main body 10 when the second rotor module 31 flips to the second flipping angle. The flipping unit 321 can be locked when it flips to the second flipping angle to lock the second rotor module 31.

[0045] It can be understood that the setting of the flipping axis parallel to the length direction of the main body 10 and the cooperation of the flipping unit 321 with the corresponding flipping cooperation structure 11 on the main body 10 are beneficial to improving the flipping stability of the flipping assembly 30. In the embodiments of the present application, at least two flipping units 321 are used to cooperate and connect with at least two flipping cooperation structures 11 on the main body 10, so that the second rotor module 31 can be better deployed and superposed with the first rotor module 20.

[0046] Please refer to Figure 5 In some embodiments, at least one flipping unit 321 in the flipping module 32 can be locked when it flips to the second flipping angle. In one embodiment, all the flipping units 321 in the flipping module 32 can be locked when they flip to the second flipping angle.

[0047] In some embodiments, the host 10 further includes a locking fitting 12, and each flipping fitting structure 11 is installed with a corresponding locking fitting 12. The flipping fitting structure 11 includes a limiting portion 111. The flipping unit 321 includes an abutting portion 3211, and the abutting portion 3211 is configured to abut against the limiting portion 111 when the flipping unit 321 is flipped to the second flipping angle and be limited by the limiting portion 111. The flipping module 32 further includes a locking connecting member 322, and each flipping unit 321 is installed with a corresponding locking connecting member 322. The locking connecting member 322 is configured to connect with the corresponding locking fitting 12 when the flipping unit 321 is flipped to the second flipping angle, so as to lock the flipping unit 321 at the second flipping angle.

[0048] It can be understood that when the flipping unit 321 is flipped to the second flipping angle, its abutting portion 3211 abuts against the limiting portion 111 of the flipping fitting structure 11, so that it is limited by the limiting portion 111 of the flipping fitting structure 11 and cannot be further flipped. Further, the locking connecting member 322 installed on the flipping unit 321 is flipped along with the flipping unit 321, and is connected and matched with the locking fitting 12 installed on the flipping fitting structure 11 when the flipping unit 321 is flipped to the second flipping angle, so as to lock the flipping unit 321 and the second rotor module 31. Wherein, the locking connecting member 322 and the locking fitting 12 can be connected and matched by means of snap connection, magnetic attraction connection, etc.

[0049] In some embodiments, the host 10 is provided with a blocking structure on the flipping stroke of the flipping unit 321. The blocking structure includes two mutually perpendicular blocking surfaces. The flipping unit 321 is generally in an L-shaped structure, and the L-shaped structure includes two mutually perpendicular connecting portions. When the flipping unit 321 is flipped to the second flipping angle, each connecting portion is disposed opposite to a corresponding blocking surface. At least one set of the relatively disposed connecting portions and the blocking surfaces can abut against each other. Wherein, the limiting portion 111 is disposed on the blocking surface, or the blocking surface serves as the entire limiting portion 111, and the structure (such as a contact point, a contact edge or a contact surface, etc.) on the connecting portion for abutting against the blocking surface is the abutting portion 3211. Exemplarily, the locking fitting 12 and the locking connecting member 322 are respectively disposed on one set of the relatively disposed connecting portions and the blocking surface.

[0050] Specifically, in one embodiment, one of the locking fitting 12 and the locking connecting member 322 is a magnetic attracting member, and the other is a magnetic attracting mating member. The magnetic attracting member and the magnetic attracting mating member are magnetically connected when the flipping unit 321 is flipped to the second flipping angle. Exemplarily, one of the magnetic attracting member and the magnetic attracting mating member is a magnet, and the other is a magnetically attractable metal member, or both the magnetic attracting member and the magnetic attracting mating member are magnets.

[0051] It can be understood that the locking connector 322 and the locking fitting 12 in the embodiments of the present application adopt a magnetic attraction connection method. When the user unfolds the second rotor module 31, the second rotor module 31 can be locked without additional operations, and when storing, an external force greater than the magnetic attraction force can be applied to separate the locking connector 322 and the locking fitting 12 from each other, thereby completing the unlocking, which is beneficial to reducing the learning cost and operation difficulty of the user.

[0052] Please refer to Figures 5 to 7 , in some embodiments, the flipping and mating structure 11 is provided with a hinge hole 112, and the flipping unit 321 includes a connecting portion 3212 and a hinge portion 3213. The connecting portion 3212 is connected to the second rotor module 31. The connecting portion 3212 and the hinge portion 3213 are respectively located at two ends of the flipping unit 321 in the length direction, the hinge portion 3213 is hinged to the hinge hole 112, the hinge axis of the hinge portion 3213 is coaxial with the flipping axis, and the hinge axis of the hinge portion 3213 is perpendicular to the length direction of the flipping unit 321.

[0053] It can be understood that the flipping unit 321 can flip relative to the main body 10 around the flipping axis through the hinge between the hinge portion 3213 and the hinge hole 112, and is connected to the second rotor module 31 through the connecting portion 3212 to drive the second rotor module 31 to flip.

[0054] Exemplarily, in some embodiments, the flipping unit 321 adopts the L-shaped structure in the above embodiments, the connecting portion 3212 is one of the connecting parts in the L-shaped structure, and is always located outside the main body 10. The limiting portion 111 in the above embodiments can be configured as a part of the outer contour of the main body 10 and is located on the moving stroke of the connecting portion 3212. The abutting portion 3211 is configured as a contact surface on the connecting portion 3212. When the flipping unit 321 flips to the second flipping angle, the abutting portion 3211 follows the connecting portion 3212 to flip until it abuts against a part of the outer contour of the main body 10, so that the flipping unit 321 is limited.

[0055] In some embodiments, the hinge portion 3213 is a disk protruding outward, the disk is received in the hinge hole 112, and is in clearance fit with the hinge hole 112 to achieve the hinge.

[0056] In some embodiments, in order to facilitate the assembly of the whole unmanned aerial vehicle 100, the flipping and mating structure 11 is further provided with a guiding groove 113, the guiding groove 113 communicates with the hinge hole 112 respectively, and the hinge portion 3213 can enter the hinge hole 112 through the guiding groove 113.

[0057] It can be understood that the flipping cooperation structure 11 on the host 10 enables the hinge part 3213 of the flipping assembly 30 to enter the hinge hole 112 after being guided through the guiding groove 113 by providing the guiding groove 113 communicating with the hinge hole 112, so as to complete the assembly. Exemplarily, the guiding groove 113 includes a first opening and a second opening which are oppositely arranged. The first opening communicates with the hinge hole 112, and the second opening communicates with the outside. The width of the second opening is greater than that of the first opening, and it is easier for the hinge part 3213 to enter from the guiding groove 113, which is beneficial to improving the assembly efficiency.

[0058] Please review Figure 6 and Figure 7 In some embodiments, the flipping cooperation structure 11 further includes a clamping part 114. The clamping part 114 is arranged on the side wall of the guiding groove 113 and is located at the communication part of the hinge hole 112 and the guiding groove 113. The clamping part 114 is used to clamp the hinge part 3213 when the hinge part 3213 is connected to the hinge hole 112, so as to limit the hinge part 3213 from disengaging from the hinge hole 112.

[0059] It can be understood that the flipping cooperation structure 11 of the embodiment of the present application avoids the hinge part 3213 from disengaging from the hinge hole 112 by providing the clamping part 114 at the communication part of the guiding groove 113 and the hinge hole 112 to clamp the hinge part 3213 when the hinge part 3213 is received in the hinge hole 112. In some embodiments, the guiding groove 113 includes two oppositely arranged side walls, and the clamping part 114 includes two convex parts 1141. Each convex part 1141 is arranged on a corresponding side wall of the guiding groove 113. The two convex parts 1141 are oppositely arranged and are located at the communication part of the hinge hole 112 and the guiding groove 113. The clamping part 114 can generate a certain elastic deformation when being extruded outward by the hinge part 3213, that is, the two convex parts 1141 move away from each other when being extruded outward by the hinge part 3213, so that the hinge part 3213 can enter the hinge hole 112 from the guiding groove 113, and recover the elastic deformation after the hinge part 3213 enters the hinge hole 112 to clamp the hinge part 3213.

[0060] In some embodiments, the flipping cooperation structure 11 is further provided with a receiving groove 115. The guiding groove 113 and the hinge hole 112 are arranged on the inner side wall of the receiving groove 115. The flipping unit 321 is received in the receiving groove 115 and can flip relative to the host 10 around the hinge axis of the hinge part 3213 in the receiving groove 115.

[0061] It can be understood that the flipping cooperation structure 11 is provided with the receiving groove 115 to receive and protect the flipping unit 321, so that it is not easily damaged by external forces during either the flight or storage of the drone 100.

[0062] In some embodiments, the receiving groove 115 includes two oppositely arranged inner sidewalls 1151. Either the hinge holes 112 or the guiding grooves 113 are arranged in pairs. Each hinge hole 112 is provided on the inner sidewall 1151 of a corresponding receiving groove 115, and each guiding groove 113 is provided on the inner sidewall 1151 of a corresponding receiving groove 115. The hinge hole 112 and the guiding groove 113 on the same inner sidewall 1151 communicate with each other.

[0063] The hinge parts 3213 of any one of the flipping units 321 are arranged in pairs. The hinge axes of the respective hinge parts 3213 in the same flipping unit 321 are coaxial. Each hinge part 3213 is connected to a corresponding hinge hole 112 and can enter the corresponding hinge hole 112 through the corresponding guiding groove 113.

[0064] It can be understood that each flipping unit 321 is configured with two oppositely arranged hinge parts 3213. Each hinge part 3213 can enter the corresponding hinge hole 112 from the corresponding guiding groove 113 and is hinged to the corresponding hinge hole 112, thereby further improving the reliability of the entire flipping module 32.

[0065] Please refer to Figure 8 and Figure 9 As shown in, in some embodiments, the hinge holes 112 communicate with the inside of the host 10. The flipping unit 321 is provided with a lead wire bin 32141, a wire inlet 3215, and a wire outlet 3216. The wire inlet 3215 is provided on the connecting part 3212. The wire inlet 3215 is used to connect the electrical connection wire 311 of the second rotor module 31. The wire outlet 3216 is provided on the hinge part 3213 and communicates with the hinge hole 112. The lead wire bin 32141 is used to partially receive the electrical connection wire 311 of the second rotor module 31 and introduce the electrical connection wire 311 of the second rotor module 31 into the inside of the host 10 through the hinge hole 112.

[0066] It can be understood that by providing the lead wire bin 32141, the wire inlet 3215, the wire outlet 3216, etc. on the flipping unit 321, the electrical connection wire 311 for connecting the host 10 on the second rotor module 31 is connected to the host 10 in an internal wiring manner. Specifically, the electrical connection wire 311 of the second rotor module 31 enters the lead wire bin 32141 through the wire inlet 3215, passes through the lead wire bin 32141, and then is led out through the wire outlet 3216 and the hinge hole 112 into the inside of the host 10. The internal wiring method adopted in the embodiments of the present application is beneficial to avoiding the problem of wire entanglement during the flipping process of the flipping assembly 30, and is also beneficial to protecting the electrical connection wire 311 of the second rotor module 31 from being damaged, thereby improving the reliability of the drone 100.

[0067] In some embodiments, the flipping unit 321 includes a lead wire bin main body 3214 and a bin cover 3217. The lead wire bin main body 3214 is provided with an opening communicating with the lead wire bin 32141. The lead wire bin main body 3214 and the bin cover 3217 are detachably connected. The bin cover 3217 is used to cover the opening of the lead wire bin 32141. During actual assembly and maintenance, the operator can remove the bin cover 3217 and adjust the electrical connection wire 311 of the second rotor module 31 through the opening of the lead wire bin 32141. Exemplarily, the lead wire bin main body 3214 and the bin cover 3217 can be detachably connected by screws or by snap connection or other means.
