[0002] In existing technologies, when flying drones are used to transport goods, the goods are usually transported by slinging. However, when the drone moves from flight to hovering, the goods will swing forward due to inertia. Since the magnitude of inertia is related to the weight of the goods, the effect of inertia can be ignored when transporting lighter goods. However, when the weight of the goods is large, the swinging of the goods caused by inertia has a significant impact on the hovering of the drone. Therefore, a technical solution is needed to solve the above problems. Utility Model Content

[0023] like Figures 1-4 As shown, this embodiment discloses a hoisting assembly, including a support 21 and an anti-sway assembly 23.

The two main pipe frames 211 are connected by multiple connecting pipe brackets 213. The distance between the lower ends of the two main pipe frames 211 is greater than the distance between the upper ends of the two main pipe frames 211, making the support 21 have a trapezoidal shape, which provides better stability in terms of support. The connecting strip 212 is fixedly installed on the upper end of the main pipe frame 211. Both ends of the tube body of the main pipe frame 211 are located at the upper end of the main pipe frame 211.

The connector 2312 is fitted onto the first rod body 2311 and fixed by riveting, making the structure more stable and robust.

[0025] The second connecting rod 232 is fixedly connected to the first connecting rod 231. There are two second connecting rods 232, each including a second rod body 2321 and two third rod bodies 2322. The two third rod bodies 2322 are respectively connected to the two first rod bodies 2311. The first rod body 2311 passes through the upper end of the third rod body 2322, and the second rod body 2321 is inserted into the lower end of the two third rod bodies 2322. The first connecting rod 231 and the second connecting rod 232 are connected by a sleeve or riveting. The third rod body 2322 is perpendicular to the first rod body 2311. The first rod body 2311 and the third rod body 2322 are perpendicular to each other in the horizontal direction. The anti-sway mechanism 233 is located between the two second connecting rods 232, making the connection between the first connecting rod 231, the second connecting rod 232, and the anti-sway mechanism 233 more stable.

[0026] The anti-sway mechanism 233 includes a fixed plate 2331, a first connecting seat 2332, a second connecting seat 2333, a shaft 2334, a third connecting rod 2335, and a cable management buckle 2336.

The first connecting seat 2332 is fixedly installed on the fixed plate 2331, and the second connecting seat 2333 is rotatably connected to the first connecting seat 2332. 2332 is installed on the lower end face of the fixing plate 2331. The first connecting seat 2332 opens downwards. The first bearing 23321 is installed on the two opposite side walls of the first connecting seat 2332. The third connecting rod 2335 connects the second connecting seat 2333 and the first bearing 23321. The second connecting seat 2333 can rotate about the third connecting rod 2335 as the central axis. The cable management buckle 2336 is fixedly installed on the upper end face of the fixing plate 2331 and can organize the power cord and connecting wires.

[0027] The shaft 2334 is mounted on the second connecting seat 2333. The sensing assembly 234 includes a swing arm 2341 and a hanging ring 2342. The swing arm 2341 is located at the upper end of the sensing assembly 234, and at least partially located within the second connecting seat 2333. The swing arm 2341 is rotatably connected to the shaft 2334. The upper end of the swing arm 2341 is connected to the shaft 2334 via a second bearing 23341, allowing the swing arm 2341 to rotate about the shaft 2334 as a central axis. The third connecting rod 2335 is perpendicular to the shaft 2334 in the horizontal direction, enabling the sensing assembly 2341 to rotate. The sensing component 234 can swing in any direction relative to the first connecting seat 2332. The hanging ring 2342 is located at the lower end of the sensing component 234. The sensing component 234 is equipped with an offset sensor and a weight sensor. The weight sensor can sense the weight of the object suspended on the hanging ring 2342. The offset sensor can sense the angle of swing of the sensing component 234 caused by the suspended object, and then transmit a signal to the flight platform 1 to control the UAV to move in the swing direction of the object, thereby eliminating the inertia of the suspended object and making the UAV more stable when hovering.

[0028] More preferably, the second connecting seat 2333 is provided with a plurality of inclined surfaces 23331, the inclined surfaces 23331 are located at the lower edge of the inner side wall of the second connecting seat 2333, and the inclined surfaces 23331 can prevent the swing rod 2341 from colliding with the lower edge of the second connecting seat 2333 when swinging at a large amplitude.
