[0002] A drone is an unmanned aircraft controlled by radio remote control equipment and its own program control device, or by an onboard computer, either fully or intermittently. In recent years, drones have received increasing attention due to their simple structure, convenient operation, and high safety performance.
[0003] A drone includes a fuselage and multiple wings fixed to the fuselage. In the prior art, the wings are generally not detachably fixed to the fuselage, making it inconvenient to carry the drone when going out. Alternatively, the method of detaching and assembling the wings from the fuselage is complicated, making it inconvenient to detach and assemble the wings.
[0004] The above content is only used to help understand the technical solution of the invention and does not represent an admission that the above content is prior art. Summary of the Invention
[0005] The main objective of this invention is to propose a drone that aims to improve the ease of assembling and disassembling the wings and fuselage in existing drone structures.
[0006] To achieve the above objectives, the present invention proposes a type of unmanned aerial vehicle (UAV) comprising:
[0007] body;
[0008] The wing has a receiving cavity with openings at both ends at its root;
[0009] An active mechanism is disposed in the accommodating cavity and detachably connects the fuselage and the wing. The active mechanism includes a first elastic element, two second end caps, and two oppositely arranged connecting members. The ends of the two connecting members that are close to each other are connected through the first elastic element.

The two second end caps are disposed in the accommodating cavity and fixedly connected to the wing. One of the second end caps is provided with a limiting rib or a limiting groove, and one of the connecting members is provided with a corresponding limiting groove or limiting rib. The limiting groove extends along the length direction of the first elastic element.
[0010] The first elastic member naturally extends, and the ends of the two connecting members that are far apart from each other pass through the openings at both ends of the receiving cavity and engage with the fuselage. The limiting rib is located in the limiting groove to prevent the wing from rotating relative to the fuselage. The first elastic member contracts, and the ends of the two connecting members can move relative to each other to separate from the fuselage.
[0011] In one embodiment, the movable mechanism further includes a sleeve, the first elastic element is disposed in the sleeve, the two ends of the sleeve are respectively sleeved on the ends of the two connecting members that are close to each other, the two connecting members can move along the axial direction of the sleeve, the drone further includes a foot, the side wall of the accommodating cavity has a slot, the first end of the foot passes through the slot and is sleeved on the sleeve.
[0012] In one embodiment, the connector includes two half-shafts and two oppositely arranged first end caps. The two half-shafts are connected at their close ends by a first elastic member.

When the half-shaft rotates relative to the first end cover to a first position, the first stop block and the second stop block are positioned opposite each other to engage the half-shaft with the first end cover. When the half-shaft rotates relative to the first end cover to a second position, the first stop block and the second stop block are misaligned, and the half-shaft moves relative to the first end cover along its own axial direction. The two half-shafts can move relative to each other to remove the landing gear from the wing.
[0014] In one embodiment, a handle is provided on the outer wall of the half-shaft. The handle is located between the sleeve and the second end cap and in the receiving cavity. The motor drives the second rotating shaft to rotate, causing the tripod to open or fold. When the tripod is in the folded state, the tripod lies flat against the underside of the wing and covers the slot. When the tripod is in the open state, the tripod opens the slot and the handle faces the slot.
[0015] In one embodiment, a guide strip is provided on the inner wall of the sleeve, the guide strip extends along the axial direction of the sleeve, and a boss is provided on the side wall of the half shaft near one end of the sleeve, the boss having a notch for the guide strip to pass through, and the half shaft moves along the guide strip.

[0017] The boss is a second annular platform, and the outer diameter of the second annular platform is larger than the diameter of the openings at both ends of the sleeve.
[0018] In one embodiment, the fuselage includes a housing and a drive mechanism. The drive mechanism is disposed within the housing and includes a motor, a second rotating shaft, and a third rotating shaft. The motor is drively connected to the second rotating shaft. The second rotating shaft has a first engaging portion and a second engaging portion arranged coaxially. The third rotating shaft has a third engaging portion and a fourth engaging portion arranged coaxially. The third engaging portion and the fourth engaging portion are rotatably connected, and the fourth engaging portion is fixedly connected to the housing. The two half-shafts are respectively the first half-shaft and the second half-shaft.
[0019] The end face of the first half-shaft away from the sleeve engages with the first meshing part, and the end face of the first end cap sleeved on the first half-shaft engages with the second meshing part. The first end cap sleeved on the first half-shaft is rotatable relative to the second end cap. The end face of the second half-shaft away from the sleeve engages with the third meshing part, and the end face of the first end cap sleeved on the second half-shaft engages with the fourth meshing part. The motor drives the half-shaft through the second rotating shaft to drive the sleeve and the foot bracket to rotate together.
[0020] In one embodiment, the drive mechanism further includes a gear, and the motor is connected to the second rotating shaft via the gear. The second meshing part has a first meshing section and a second meshing section distributed along its axial direction.

The first end cap sleeved on the second half shaft extends into the second mounting hole and engages with the fourth engaging part.
[0022] In one embodiment, the outer wall of the sleeve is provided with a groove extending along the length of the sleeve, and slots are formed at opposite ends of the groove. The first end of the leg is provided with a socket cavity with openings at both ends, the sleeve is disposed in the socket cavity, and the inner wall of the socket cavity is provided with a locking block adapted to the groove. The locking block is embedded in the groove to prevent the first end of the leg from rotating relative to the sleeve. The locking block can pass through the slot, and the first end of the leg can move axially along the sleeve to detach the leg from the sleeve.
[0023] The technical solution of this invention connects two connectors passing through both ends of the wing root using a first elastic element, and achieves convenient assembly and disassembly of the wing from the fuselage through the meshing connection of the two connectors with the fuselage. In the UAV of this invention, the wing root is fitted onto the movable mechanism. When the wing needs to be removed from the fuselage, the first elastic element is compressed, causing the two connectors to move towards each other along the limiting groove, thereby separating the two first end caps from the fuselage. Conversely, if the wing is to be mounted on the fuselage, the first elastic element must first be compressed, causing the two connectors to move towards each other, with the ends of the two connectors facing away from each other corresponding to the meshing parts on the fuselage. Then, the first elastic element is allowed to extend naturally, and the two connectors will move away from each other until their end faces mesh with the corresponding meshing parts on the fuselage. The limiting rib is engaged in the limiting groove, ensuring that the wing is securely mounted on the fuselage. Attached Figure Description

[0039] This invention proposes a drone 100.
[0040] Please see Figures 1-8In this embodiment of the invention, the drone 100 includes a fuselage 110, a wing 130, and a movable mechanism. The root of the wing 130 is provided with a receiving cavity having openings at both ends. The movable mechanism is disposed in the receiving cavity and detachably connects the fuselage 110 and the wing 130. The movable mechanism includes a first elastic element 153, two second end caps 175, and two oppositely arranged connecting members 140. The ends of the two connecting members 140 that are close to each other are connected by the first elastic element 153. The two second end caps 175 are respectively sleeved on the ends of the two connecting members 140 that are far from each other. The two second end caps 175 are disposed in the receiving cavity and fixedly connected to the wing 130. The second end cap 175 is provided with a limiting rib or a limiting groove (not shown in the figure). The limiting rib can be a small protrusion, and the limiting groove can be cuboid in shape. One of the connecting members 140 is provided with a corresponding limiting groove or limiting rib (not shown in the figure). The limiting groove extends along the length direction of the first elastic member 153. The first elastic member 153 naturally extends, and the ends of the two connecting members 140 that are far apart from each other pass through the openings at both ends of the receiving cavity and engage with the fuselage 110. The limiting rib is located in the limiting groove to prevent the wing 130 from rotating relative to the fuselage 110. When the first elastic member 153 contracts, the ends of the two connecting members 140 can move relative to each other to separate from the fuselage 110.
[0041] In an embodiment of the present invention, two second end caps 175 are respectively disposed at both ends of the accommodating cavity and fixedly connected to the wing 130. The two second end caps 175 can be selectively integrally formed with the root of the wing 130 or separately formed. In a specific embodiment, the second end cap 175 is separately formed with the wing 130. The outer side wall of the second end cap 175 is provided with a plurality of protrusions arranged sequentially and spaced apart along its axial direction to increase the fixing force between the second end cap 175 and the wing 130.
[0042] Limiting ribs or limiting grooves may be provided on the inner sidewalls of both second end caps 175. Correspondingly, limiting grooves or limiting ribs are provided at the ends of both connectors 140 that are far apart from each other. Alternatively, limiting ribs or limiting grooves may be selectively provided on one of the two first end caps 171, and corresponding limiting grooves or limiting ribs may be provided on the connectors 140 fitted onto the first end cap 171 with the limiting ribs or limiting grooves. In a specific embodiment, a limiting groove is provided only on one of the two first end caps 171, and correspondingly, a limiting rib corresponding to the limiting groove is provided only on one of the two first connectors 140.
[0043] The technical solution of the present invention connects two connectors 140 that pass through both ends of the root of the wing 130 by using a first elastic member 153, and connects the two connectors 140 with the fuselage 110 by meshing, thereby realizing the convenience of assembling and disassembling the wing 130 and the fuselage 110. In the UAV 100 of the present invention, the root of the wing 130 is fitted onto the movable mechanism. When the wing 130 needs to be removed from the fuselage 110, the first elastic member 153 is compressed, causing the two connecting members 140 to move towards each other along the limiting groove, thereby separating the two first end caps 171 from the fuselage 110. Conversely, if the wing 130 is to be installed on the fuselage 110, the first elastic member 153 must first be compressed, causing the two connecting members 140 to move towards each other, and causing the ends of the two connecting members 140 that are far apart from each other to correspond to the meshing parts that are respectively provided on the fuselage 110. Then, the first elastic member 153 is allowed to extend naturally, and the two connecting members 140 will move away from each other until their end faces mesh with the corresponding meshing parts on the fuselage 110. The limiting rib is locked in the limiting groove, so that the wing 130 is securely installed on the fuselage 110.
[0044] Please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 Furthermore, the movable mechanism also includes a sleeve 155, in which the first elastic element 153 is disposed. Both ends of the sleeve 155 are respectively fitted onto the adjacent ends of the two connecting members 140. The two connecting members 140 are movable along the axial direction of the sleeve 155. The drone 100 also includes a landing gear 190. A slot 131a is formed in the side wall of the accommodating cavity. The first end of the landing gear 190 passes through the slot 131a and is fitted onto the sleeve 155. The landing gear 190 is mounted on the wing 130 via the sleeve 155 and the movable mechanism. The wing 130 can be detached from the fuselage 110 along with the landing gear 190.
[0045] Please see Figure 6 , Figure 7 and Figure 8In one embodiment, the connector 140 includes two half-shafts 151 and two oppositely arranged first end caps 171. The two half-shafts 151 are connected to form a first rotating shaft 150 by a first elastic member 153. The two first end caps 171 are sleeved on the ends of the two half-shafts 151 that are far apart from each other. The second end cap 175 is sleeved on the first end cap 171. The second end cap 175 is provided with a second elastic member 173. The two ends of the second elastic member 173 are respectively connected to the first end cap 171 and the second end cap 175. The half-shaft 151 is rotatable relative to the first end cover 171. A first stop block 1713 protrudes from the inner side wall of the first end cover 171, and a second stop block 1511 protrudes from the side wall of the half-shaft 151 away from the sleeve 155. When the half-shaft 151 rotates relative to the first end cover 171 to a first position, the first stop block 1713 and the second stop block 1511 are positioned opposite each other, preventing the two half-shafts 151 from moving towards each other, and the half-shaft 151 is engaged with the first end cover 171. When the half-shaft 151 rotates to the second position relative to the first end cover 171, that is, when the half-shaft 151 rotates away from the first position relative to the first end cover 171, the first stop block 1713 and the second stop block 1511 are misaligned, the half-shaft 151 can move relative to the first end cover 171 along its own axial direction, the first elastic element 153 can be compressed, and the two half-shafts 151 move relative to each other so that the footrest 190 can be removed from the wing 130.
[0046] Please see Figure 8 Specifically, the first end cap 171 has a first annular platform 15111 protruding from its outer periphery near one end of the sleeve 155. The first annular platform 15111 is located inside the second end cap 175, and the outer diameter of the first annular platform 15111 is larger than the diameter of the two ends of the first end cap 171. The second elastic member 173 is sandwiched between the first annular platform 15111 and the second end cap 175. The half shaft 151 has a second annular platform 1513 on its side wall near one end of the sleeve 155. The outer diameter of the second annular platform 1513 is larger than the diameter of the openings at both ends of the sleeve 155. Understandably, the first annular platform 15111 can also be a plurality of protrusions spaced apart on the outer periphery of the first end cap 171 near the end of the sleeve 155, as long as they can prevent the first end cap 171 from completely detaching from the second end cap 175; the second annular platform 1513 can also be a plurality of protrusions spaced apart on the outer periphery of the half shaft 151 near the end of the sleeve 155, as long as they can prevent the ends of the two half shafts 151 that are close to each other from leaving the sleeve 155.
[0047] Please see Figure 1 , Figure 3 and Figure 8 Furthermore, each of the two half-shafts 151 has a handle 157 on its outer side wall. The handle 157 is located between the sleeve 155 and the second end cap 175 and is located in the receiving cavity. The handle 157 can be pulled through the slot 131a to retract the first elastic element 153 and the second elastic element 173, thereby facilitating the removal of the wing 130 from the fuselage 110, or facilitating the removal of the landing gear 190 from the wing 130.
[0048] Please see Figure 6 and Figure 8 In one embodiment, the fuselage 110 includes a housing 111 and a drive mechanism. The drive mechanism is disposed in the housing 111. The drive mechanism 113 includes a motor 1131, a second rotating shaft 1133, and a third rotating shaft 1135. The motor 1131 is drively connected to the second rotating shaft 1133, and the second rotating shaft 1133 is rotatably connected to the housing 111. The second rotating shaft 1133 has a first engaging portion 11331 and a second engaging portion 11332 arranged coaxially. The diameter of the second engaging portion 11332 is smaller than the diameter of the first engaging portion 11331. The third rotating shaft 1135 has a third engaging portion 11351 and a fourth engaging portion 11355 arranged coaxially. The fourth engagement portion 11352 has a smaller diameter than the third engagement portion 11351. The third engagement portion 11351 is rotatably connected to the fourth engagement portion 11352, and the fourth engagement portion 11352 is fixedly connected to the housing 111. The first engagement portion 11331 and the second engagement portion 11332 are both composed of a plurality of protrusions arranged circumferentially along the second rotating shaft 1133, and grooves are formed between the plurality of protrusions. The third engagement portion 11351 and the fourth engagement portion 11352 are both composed of a plurality of protrusions arranged circumferentially along the third rotating shaft 1135, and grooves are formed between the plurality of protrusions.
[0049] The two half-shafts 151 are respectively a first half-shaft 151 and a second half-shaft 151. In a specific embodiment, both the first half-shaft 151 and the second half-shaft 151 are cylindrical. The end face of the first half-shaft 151 away from the sleeve 155 engages with the first engaging part 11331, and the end face of the first end cap 171 sleeved on the first half-shaft 151 engages with the second engaging part 11332. The first end cap 171 sleeved on the first half-shaft 151 is rotatable relative to the second end cap 175. The end face of the second half-shaft 151 away from the sleeve 155 engages with the third engagement part 11351, and the end face of the first end cap 171 sleeved on the second half-shaft 151 engages with the fourth engagement part 11352. Since the outer peripheral wall of the first end cap 171 sleeved on the second half-shaft 151 is provided with a limiting rib, and the inner peripheral wall of the second end cap 175 is provided with a corresponding limiting groove, the first end cap 171 sleeved on the second half-shaft 151 cannot rotate relative to the second end cap 175 sleeved on it. Understandably, the end faces of the two half-shafts 151 that are far apart from each other are each formed with a meshing groove to mesh with the first meshing part 11331 and the third meshing part 11351 respectively. The meshing groove may be composed of a plurality of grooves arranged sequentially at intervals along the axial direction of the half-shafts 151; and the end faces of the two first end caps 171 are each formed with a meshing groove to mesh with the second meshing part 11332 and the fourth meshing part 11352 respectively. The meshing groove may be composed of a plurality of grooves between protrusions arranged sequentially at intervals along the axial direction of the first end caps 171. In this embodiment, the motor 1131 can drive the half-shaft 151 through the second rotating shaft 1133 to rotate the sleeve 155 and the foot 190 together, so as to realize the folding or opening of the foot 190. Specifically, the motor 1131 drives the second rotating shaft 1133 to rotate, thereby driving the first end cover 171 and the first half-shaft 151, which are engaged with the second rotating shaft 1133, to rotate. The rotation of the first half-shaft 151 drives the sleeve 155, the foot 190 and the second half-shaft 151 to rotate together.
[0050] Please see Figure 3 When the tripod 190 is in the folded state, it lies flat against the underside of the wing 130, covering the slot 131a, and the handle 157 is hidden in the receiving slot. When the tripod 190 is in the open state, it opens the slot 131a, and the handle 157 faces the slot 131a, making it easy to pull the two half-shafts 151 towards each other.
[0051] Please see Figure 6More specifically, the drive mechanism 113 further includes a gear 1132, which includes a driving gear and a driven gear. The motor 1131 is connected to the second rotating shaft 1133 in sequence through the driving gear and the driven gear. The second meshing part 11332 has a first meshing section and a second meshing section distributed along its axial direction. The first meshing section meshes with the gear 1132, and the second meshing section meshes with the end face of the first end cover 171 sleeved on the first half shaft 151.
[0052] Please see Figure 8 In order to prevent the sleeve 155 from causing the bracket 190 to rotate relative to the half shaft 151, a guide strip 1551 is provided on the inner wall of the sleeve 155. The guide strip 1551 extends along the axial direction of the sleeve 155. The second annular platform 1513 has a notch 1513a for the guide strip 1551 to pass through. The half shaft 151 can move along the guide strip 1551.
[0053] Please see Figure 6 Similarly, to prevent the tripod 190 from rotating relative to the sleeve 155, the outer wall of the sleeve 155 is provided with a groove 1553, which extends along the length of the sleeve 155. The first end of the tripod 190 is provided with a connecting cavity 190a with openings at both ends. The sleeve 155 is disposed in the connecting cavity 190a. The inner wall of the connecting cavity 190a is provided with a locking block 191 that matches the groove 1553. The locking block 191 is embedded in the groove 1553 to prevent the first end of the tripod 190 from rotating relative to the sleeve 155. In a specific embodiment, there are multiple grooves 1553, which are arranged sequentially along the outer peripheral wall of the sleeve 155. The inner wall of the connecting cavity 190a is provided with multiple locking blocks 191, which are arranged one-to-one with the multiple grooves 1553.
[0054] Please continue reading. Figure 6 To facilitate the assembly and disassembly of the tripod 190 and the sleeve 155, slots 131a (not shown in the figure) are provided at opposite ends of the slot 1553. The locking block 191 can pass through the slots 131a, and the first end of the tripod 190 can move axially along the sleeve 155 to remove the tripod 190 from the sleeve 155.
[0055] Please see Figures 2-5In a specific embodiment of the present invention, a mounting groove 111a is recessed on the outer surface of the periphery of the housing 111. A first mounting hole 111a1 and a second mounting hole 111a2 are respectively opened on the side walls of the mounting groove 111a on opposite sides. The first mounting hole 111a1 and the second mounting hole 111a2 respectively connect the mounting groove 111a to the interior of the housing 111. The second engagement section of the second engagement part 11332 and the second engagement part 11332 are disposed in the first mounting hole 111a1. The first end cap 171, which is sleeved on the first half shaft 151, extends into the first mounting hole 111a1 and engages with the second engagement part 11332. The fourth engagement part 11352 and the third engagement part 11351 are disposed in the second mounting hole 111a2. The first end cap 171, which is sleeved on the second half shaft 151, extends into the second mounting hole 111a2 and engages with the fourth engagement part 11352.
