[0043] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] As an expanded application of drone operations, the hoisting mode is very practical in environments where crossing heights or overland routes is inconvenient, significantly improving cargo handling efficiency. Of course, due to the relatively limited payload of drones, existing hoisting frames are minimized as much as possible, but this comes with some challenges, such as limited lifting points and inconvenient adjustment.

[0047] See also Figures 1 to 3 , exemplarily showing the structure of the lifting frame provided by the utility model and its application to the structure of the drone. Figure 1 and Figure 2 The lifting frame 1 provided by the present invention is a specific application example structure and may include a main body 11 with an internal cavity, and the main body 11 is mainly made by blow molding.

[0048] The top side of the main body 11 may be provided with a plurality of accommodating grooves 12, and each accommodating groove 12 is used to provide users with accommodating space for corresponding tools such as ropes and locks. A connecting edge 13 may also be provided on the circumferential side of the main body 11, and the connecting edge 13 includes a connecting surface 131 located on the bottom side, and the connecting surface 131 is used to be installed on the drone frame, so as to achieve relative fixation between the lifting frame 1 and the drone. Preferably, the main body 11 and the connecting edge 13 are integrally formed, and the connecting edge 13 may also have a structure with a hollow interior. In addition, the connecting edge 13 has a plurality of hanging point setting sections 132 extending in the circumferential direction of the main body 11, and each of the hanging point setting sections 132 is provided with a plurality of hanging points for winding ropes, and each hanging point is relatively independently set.

[0049] In the present invention, the main body 11 of the lifting frame 1 adopts a hollow structure, which can reduce the deadweight of the lifting frame 1. At the same time, a connecting edge 13 is provided on the peripheral side of the main body 11. The connecting edge 13 is used to connect and fix with the drone. At the same time, multiple lifting point setting sections 132 provided thereon provide the user with multiple lifting point options, enriching the user's lifting operation support scenarios, meeting the user's multi-scenario application needs, and making the application more flexible. In addition, multiple accommodating grooves 12 are also provided in the main body 11. Each accommodating groove 12 can provide a means of accommodating tools related to lifting operations, and can be adapted to accommodate lifting tools corresponding to various lifting points, providing support for enriching the application scenarios of the lifting frame 1.

[0050] like Figure 1As shown, the connecting edge 13 may specifically include notches 14 disposed on two opposing sides of the main body 11, with the two suspension point setting sections 132 respectively disposed within the corresponding notches 14. Furthermore, a connecting column 1321 is further disposed within the notch 14. The connecting column 1321 extends horizontally, with its ends respectively connected to two opposing walls forming the notch 14. Furthermore, multiple suspension point protrusions may be disposed on the shaft of the connecting column 1321, each of which serves as a suspension point for a cable to be wound around and secured, thereby enabling the user to selectively set multiple suspension points on the shaft of a connecting column 1321.

[0051] More specifically, the main body 11 is roughly in the shape of a rectangular parallelepiped, and accordingly, the main body 11 includes two long sides (corresponding to the sides extending in the L direction) and two wide sides (corresponding to the sides extending in the W direction), and the notch 14 is respectively located on the sides where the two wide sides of the main body 11 are located, and the hanging point protrusion can specifically be a foot column 1322. Figure 1 In the figure, the notch 14 is formed by two vertical planes extending in the L direction and one vertical plane extending in the W direction. The two ends of the connecting column 1321 are respectively connected to the two vertical planes extending in the L direction, and the vertical plane extending in the W direction can serve as an end face of the main body in the L direction.

[0052] The connecting column 1321 is provided with a plurality of foot posts 1322 arranged side by side, and each foot post 1322 provides at least one lifting point. One end of each foot post 1322 is connected to the column body of the connecting column 1321, and the other end of each foot post 1322 is connected to the main body 11. Accordingly, each foot post 1322 is located in the notch 14. Preferably, each foot post 1322 should not be too long, and the column length of the foot post 1322 can be less than or equal to 3D (D is the diameter of the cable) to avoid the winding cable from slipping during the lifting operation, resulting in inaccurate lifting position or even safety hazards, and to facilitate winding and tightening. Similarly, the spacing between the foot posts 1322 arranged side by side on the column body of the connecting column 1321 should not be too far, and the spacing can also be less than or equal to 3D. Here, each hanging point setting section 132 includes a connecting column 1321, and two foot columns 1322 are connected to the connecting column 1321. Therefore, the connecting column 1321 is divided into three sections by the two foot columns 1322. Therefore, each hanging point setting section 132 includes five hanging points, thereby enriching the use options of the hanging points.

[0053] In the present invention, in addition to the hollow structure of the main body 11, the connecting column 1321 and the foot column 1322 are hollow columns, and at least the column body of the connecting column 1321 is flush with the connecting surface 131. Accordingly, the connecting column 1321 can also serve as the structural portion for contact and installation between the lifting frame 1 and the drone. Preferably, the connecting column 1321, the foot column 1322, and the main body 11 are integrally formed and manufactured by blow molding.

[0054] The plurality of receiving grooves 12 located on the top side of the main body 11 may include a middle groove 121 and side grooves 122 located on both sides of the middle groove 121 . Figure 1 In the embodiment, the trough bodies of the respective accommodating grooves 12 are all square trough bodies, and the trough bodies are all in the length direction of the main body 11 (i.e. Figure 1 The intermediate groove 121 is wider than the side grooves 122. Furthermore, to enhance the structural strength of the accommodating grooves 12, a plurality of reinforcing ribs 16 are provided on the bottom of each accommodating groove 12 to reduce the possibility of deformation during transportation of the corresponding rope.

[0055] It is understandable that corresponding reinforcing ribs 16 can be provided at each flat surface of the main body 11 to enhance the overall structural strength of the main body 11 , thereby enabling the lifting frame 1 to have both light weight and high structural strength. Figure 1 In the figure, the reinforcing rib 16 is a convex ridge, and the extending direction of the convex ridge (W direction in the figure) is perpendicular to the extending direction of the groove body of the accommodating groove 12 (L direction in the figure).

[0056] Relative to the receiving groove 12 located on the top side of the main body 11, the main body 11 may also include a sinking portion 15 located on the bottom side of the main body 11. A connecting peripheral wall 151 is provided around the sinking portion 15. The connecting peripheral wall 151 can be used to connect to the inner periphery of the drone frame. The provision of the sinking portion 15 can lower the overall center of gravity of the lifting frame 1, helping to stably install the lifting frame 1 on the drone frame, thereby supporting more stable lifting operations.

[0057] like Figure 3As shown, the present invention also provides a drone 2, which can specifically be a multi-rotor unmanned aerial vehicle. The drone 2 can include a frame and a lifting frame 1 in each implementation structure described above, and the lifting frame 1 as above is installed on the top of the frame. Accordingly, when the drone 2 equipped with the lifting frame 1 as above is operated in the lifting mode, there are multiple lifting points for the user to choose from, which can enrich the lifting operation scenes of the drone. At the same time, since the main body 11 of the lifting frame 1 adopts a hollow structure, the drone has a greater load capacity, which supports improving the lifting efficiency. In addition, the multiple accommodating slots 12 provided on the main body 11 can also provide accommodating space for tools related to lifting operations, support users to carry more lifting tools, and further enrich the scenarios in which users use the drone for lifting operations.

[0058] In the present invention, the frame may include a tripod 21 and a supporting frame 22 , wherein the tripod 21 is mainly used to support the supporting frame 22 and related components thereon, and the supporting frame 22 is mainly used to install related electrical equipment and loads.

[0059] Here, the support frame 22 may include a square frame formed by a plurality of hollow tubes 221. Figure 2 The connecting surface 131 is connected to the top side frame surface of the square frame.

[0060] In a specific application example, the frame of the drone 2 may be provided with a plurality of weighing sensors 23, and the connection surface 131 may be provided with positioning grooves 134 corresponding to the positions of the respective weighing sensors 23, and the plurality of positioning grooves 134 may be evenly distributed around the circumference of the main body 11. Figure 2 As shown, the projection outline of the main body 11 and the connecting edge 13 on the horizontal plane is a rectangle. Four positioning grooves 134 are provided on the connecting surface 131, and the four positioning grooves 134 are respectively arranged at the four vertices of the rectangle.

[0061] Correspondingly, if Figure 3 As shown, the top of the square frame is also equipped with a weighing sensor 23 that mates with the corresponding positioning slot 134 to sense the weight of the load being hoisted by the hoisting frame 1. When the weight of the load being hoisted by the hoisting frame 1 exceeds a load threshold, the weighing sensor 23 and / or the control module can output a hoisting operation safety prompt.

[0062] In this utility model, combined with Figure 1 and Figure 3 In the projection of the square frame of the rack and the lifting frame 1 on the same horizontal plane, the lifting point setting sections 132 are all located within the square frame, thereby avoiding the cables on the lifting point setting sections 132 from causing unnecessary structural interference to other devices on the rack.

[0063] In addition, in order to avoid possible interference of the lifting frame 1 with other devices on the square frame, the connecting edge 13 further has an avoidance section 133 arranged on the circumference of the main body 11. The avoidance section 133 can separate the multiple lifting point setting sections 132 into at least two lifting point setting sections 132. Figure 1 and Figure 2 In the embodiment, the two avoidance sections 133 are respectively located on the sides where the two long sides of the main body 11 are located.

[0064] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solutions of the present invention rather than to limit it.
