Description

Technical Field

[0001] This utility model relates to the field of flying drone technology, and more specifically, to a flight platform and a drone. Background Technology

[0002] In existing technologies, some flying drones include multiple extended flight arms, on which motors and propellers are installed to drive the drone's flight. The flight arms extend outwards away from the center of the drone. In order to increase the payload of the drone, the extension length of the flight arms also increases as the size of the drone increases. This makes it very inconvenient to transport large drones. If the extended flight arms are damaged, the drone will be unable to fly normally. Therefore, a technical solution is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art, and to reduce the transport volume of the drone by folding its outer joints during transportation, thereby providing a flight platform and a drone.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model discloses a flight platform and a drone, including a frame, an outer joint, and a locking component. The frame includes multiple inner joints, each inner joint being connected to an outer joint. Each inner joint includes a first connector, and each outer joint includes a second connector. The first connector and the second connector are rotatably connected. The outer joint includes a first state and a second state. In the first state, the locking component fixes the first connector and the second connector, and the inner joint and the outer joint remain vertically extended. In the second state, the end of the outer joint away from the inner joint can rotate towards a horizontal direction close to the frame.

[0006] Furthermore, the outer joint includes a connecting arm and a connecting plate. The second connector is installed at one end of the connecting arm, and the connecting plate is installed at the other end of the connecting arm. The connecting plate has a socket that opens in a horizontal direction. Two adjacent outer joints form a group, and the two outer joints in each group rotate toward each other. The second connector has a snap-fit ​​ring, and the snap-fit ​​ring of one outer joint in a group is inserted into the socket of another outer joint.

[0007] Furthermore, the first connector includes a connecting seat with a first opening located on one side of the connecting seat in the horizontal direction. The second connector includes a connecting end, a portion of which is located within the connecting seat. The connecting seat and the connecting end are hinged together, and the connecting end is rotatable in the horizontal direction.

[0008] Furthermore, the first connector includes a limiting seat, which has a semi-annular structure, and the second connector includes a limiting surface, which is arc-shaped. In the first state, the limiting surface abuts against the inner wall of the limiting seat.

[0009] Furthermore, the locking member is installed on the first connector. The locking member includes a fixed half-ring and a movable half-ring. The fixed half-ring is fixedly installed on the first connector. One end of the movable half-ring is rotatably connected to one end of the fixed half-ring. A clamping space is formed between the fixed half-ring and the movable half-ring. The other end of the movable half-ring is detachably connected to the fixed half-ring to tighten the clamping space.

[0010] Furthermore, the locking component includes a latch and a connecting rod. One end of the connecting rod is rotatably connected to the movable half-ring, and the other end of the connecting rod is rotatably connected to the latch. The fixed half-ring has a locking end, which includes a slot and a first pressing surface. The connecting rod can be placed in the slot. The end of the latch connected to the connecting rod is a pressing end, which includes a second pressing surface. The second pressing surface is an arc surface, and the second pressing surface abuts against the first pressing surface. The latch rotates so that the end of the latch away from the pressing end gradually approaches the movable half-ring, and the connection end of the connecting rod with the movable half-ring gradually approaches the locking end.

[0011] Furthermore, the end of the latch away from the pressing end is provided with a buckle, and the outer side wall of the movable semi-ring is provided with a slot corresponding to the buckle.

[0012] A drone includes the aforementioned flight platform and hoisting assembly, wherein the frame is fixedly mounted on the upper end of the hoisting assembly.

[0013] The beneficial effects of this utility model are:

[0025] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1-9As shown, this embodiment discloses a flight platform, including a frame 11, outer joints 12, and locking components 13. The frame 11 is made of aluminum alloy and is a rectangular frame. The frame 11 includes multiple inner joints 111, with four inner joints 111 located at the four corners of the frame 11. Each inner joint 111 includes a tube and a first connector 112. The first connector 112 is located at the end of the tube and includes a connecting seat 1121 and a limiting seat 113. The connecting seat 1121 has a first opening 1122. An opening 1122 is located on one side of the horizontal direction of the connecting seat 1121. The connecting seat 1121 is hollow inside, and the top and bottom surfaces of the connecting seat 1121 are both flat. The limiting seat 113 is located at the end of the connecting seat 1121 away from the frame 11. The limiting seat 113 is provided with a second opening 1131, which communicates with the first opening 1122. The second opening 1131 and the first opening 1122 face the same direction. The second opening 1131 and the first opening 1122 allow the second connector 122 of the outer joint 12 to rotate.

[0027] like Figure 2 , Figure 4 , Figure 5 As shown, each inner joint 111 is connected to an outer joint 12. The outer joint 12 includes a second connector 122. The first connector 112 is rotatably connected to the second connector 122. The second connector 122 includes a connecting end 1221. A portion of the connecting end 1221 is located inside the connecting seat 1121. The upper and lower end surfaces of the connecting end 1221 are flat. The upper and lower end surfaces of the connecting end 1221 can respectively abut against the inner top and bottom surfaces of the connecting seat 1121. The connecting seat 1121 and the connecting end 1221 are hinged, so that the connecting end 1221 can rotate in the horizontal direction away from the second opening 1131 and the first opening 1122.

[0028] The external joint 12 includes a first state and a second state. The limiting seat 113 has a semi-ring structure. The second connector 122 includes a limiting surface 1222, which is arc-shaped. In the first state, the limiting surface 1222 abuts against the inner wall of the limiting seat 113. The limiting seat 113 can limit the rotation of the external joint 12, so that the external joint 12 extends in the same direction as the inner joint 111 in the first state, making the external joint 12 more stable in the first state.

[0029] The outer joint 12 includes a connecting arm 121 and a connecting plate 123. A second connector 122 is installed at one end of the connecting arm 121, and a connecting plate 123 is installed at the other end of the connecting arm 121. The connecting plate 123 has a socket 1231, which opens horizontally. Two adjacent outer joints 12 form a group, and the two outer joints 12 in each group rotate toward each other. The two outer joints 12 can rotate and bend towards the center, and can be folded together. The second connector 122 has a snap-fit ​​ring 1223. Since the connecting arm 121 is a hollow tube made of carbon fiber, the snap-fit ​​ring 1223 can cover the connecting arm 121. 1. Externally, it replaces the connecting arm 121 and the connecting plate 123 for snap-fit, preventing the connecting arm 121 from deforming and wearing. The snap-fit ​​ring 1223 of one outer joint 12 in a set is inserted into the socket 1231 of another outer joint 12. The part of the connecting plate 123 with the socket 1231 has elastic deformation capability. The socket 1231 can elastically deform and snap-fit ​​the snap-fit ​​ring 1223. The two outer joints 12 can support each other and remain fixed after the two outer joints 12 are bent, preventing the two outer joints 12 from moving. In this way, the volume of the entire flight platform can be reduced, which is convenient for transportation and can also protect the motors and propellers on the outer joints 12.

[0030] More preferably, the two inner joints 111 of each group have different lengths, and the two outer joints 12 of each group have different lengths, but the overall length of the outer joints 12 and inner joints 111 of each group is the same, so that the two outer joints 12 of each group can be folded together one inside and one outside, and supported by the connecting plate 123.

[0031] like Figure 6 , Figure 7 , Figure 8 As shown, in the first state, the locking member 13 fixes the first connector 112 and the second connector 122, and the inner joint 111 and the outer joint 12 remain vertically extended. In the second state, the end of the outer joint 12 away from the inner joint 111 can rotate in a horizontal direction close to the frame 11. The locking member 13 is similar to a clamp structure, which can fix the inner joint 111 and the outer joint 12 in the first state to prevent the outer joint 12 from rotating.

[0032] Locking member 13 is installed on the first connector 112. Locking member 13 includes a fixed half ring 131 and a movable half ring 132. The fixed half ring 131 is fixedly installed on the first connector 112. The fixed half ring 131 is locked to the outer circumference of the limiting seat 113 by bolts. The fixed half ring 131 and the movable half ring 132 are respectively two half rings of the clamping structure. A clamping space 135 is formed between the fixed half ring 131 and the movable half ring 132. One end of the movable half ring 132 is rotatably connected to one end of the fixed half ring 131. The movable half ring 132 can close the second opening 1131 to fix the second connector 122 in the first connector 112, so that the inner joint 111 and the outer joint 12 extend in the same direction.

[0033] Locking component 13 includes a latch 133 and a connecting rod 134. One end of the connecting rod 134 is rotatably connected to the movable half-ring 132, and the other end of the connecting rod 134 is rotatably connected to the latch 133. The fixed half-ring 131 is provided with a locking end 1311, which includes a slot 13111 and a first pressing surface 13112. When the movable half-ring 132 rotates toward the fixed half-ring 131, the connecting rod 134 can be placed in the slot 13111. The end of the latch 133 connected to the connecting rod 134 is the pressing end 1331, which includes a second pressing surface 13311. The second pressing surface 13311 is an arc surface, and the second pressing surface 13311 abuts against the first pressing surface 13112, thus fixing the connection. The semi-ring 131 has a metal part inside, and the first pressing surface 13112 is part of the metal part, which increases the wear resistance of the fixed semi-ring 131. The radius distance between the hinge point of the pressing end 1331 and the connecting rod 134 and the curved surface of the second pressing surface 13311 is different. The lock 133 rotates so that the end of the lock 133 away from the pressing end 1331 gradually approaches the movable semi-ring 132. The lock 133 rotates so that the hinge point of the pressing end 1331 and the connecting rod 134 moves away from the first pressing surface 13112. The connecting end 1221 of the connecting rod 134 and the movable semi-ring 132 gradually approaches the locking end 1311. The connecting rod 134 pulls the movable semi-ring 132 closer to the fixed semi-ring 131, which can tighten the clamp space 135.

[0034] The other end of the movable half-ring 132 is detachably connected to the fixed half-ring 131. The end of the latch 133 away from the pressing end 1331 is provided with a buckle 1332. The buckle 1332 can be supported by the torsion spring installed inside. The outer wall of the movable half-ring 132 is provided with a slot 1321 corresponding to the buckle 1332. After the latch 133 rotates to tighten the clamp space 135, the latch 133 is fixed to prevent the latch 133 from loosening.

[0035] like Figure 9As shown, this embodiment also discloses a drone, the aforementioned flight platform 1 and hoisting assembly 2, the frame 11 is fixedly installed on the upper end of the hoisting assembly 2, the drone is a large drone capable of carrying goods, when the drone is transported by car, the four outer joints 12 are folded together to reduce the volume and facilitate transportation.
