[0017] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1-3 As shown, a UAV hoisting structure includes a UAV body 1, a steel rope 2 is suspended on the lower side of the UAV body 1, and an automatic hook device is connected to the lower side of the steel rope 2;

[0019] The automatic hook device includes a frame 3, two groups of movable hooks 4 are symmetrically distributed on the lower side of the frame 3, the movable hooks 4 are hinged to the lower side of the frame 3, a one-way movable component is hinged on the outer side of the movable hook 4, a control component is installed on the upper side of the one-way movable component, a lifting box 5 is installed on the lower side of the automatic hook device, and a lifting buckle 6 matching the frame 3 and the movable hook 4 is fixedly installed on the upper side of the lifting box 5.

[0020] When in use, place the items to be hoisted inside the hoisting box 5. When the hoisting box 5 needs to be hung, control the drone body 1 to make the automatic hook device hanging on its lower side close to the hoisting buckle 6 of the hoisting box 5. Control the components and the one-way movable components to make the two movable hooks 4 in a horizontal state, and make the movable hooks 4 only rotate upward in one direction. When the two movable hooks 4 are in a horizontal state, the adjacent ends of the two movable hooks 4 are close to each other. When the movable hooks 4 abut against the hoisting buckle 6, the drone body 1 makes the frame 3 descend. Due to the gravity of the frame 3, the movable hooks 4 rotate upward during the descent of the frame 3. After the hoisting buckle 6 enters the inner side of the frame 3 and the movable hook 4, the frame 3 continues to move downward. After the upper side of the hoisting buckle 6 leaves the movable hook 4, the movable hook 4 returns to the horizontal position due to the action of gravity. At this time, the drone body 1 can take off upward to lift the hoisting box 5.

[0021] When it is necessary to release the lifting box 5, the control component can control the displacement of the one-way movable component so that the movable hook 4 can rotate downward, and the lifting box 5 is released.

[0022] The frame 3 cooperates with the movable hook 4 so that the UAV lifting device can automatically hang the lifting box 5 and automatically release the lifting box 5 when in use, thereby improving the automation degree of the UAV lifting structure, improving the lifting efficiency of the UAV, reducing the workload of the staff, and improving the safety of the UAV lifting process.

[0023] There are two groups of one-way movable components and they are symmetrically distributed left and right. The one-way movable components include a movable rod 7 and a push rod 8. The movable rod 7 is slidably connected to the push rod 8 up and down. The upper side of the push rod 8 is transmission connected to the control component. The lower side of the movable rod 7 is hinged to the movable hook 4. A straight slot 9 is opened in the middle of the push rod 8. Two linearly distributed sliding pins 10 matching the straight slot 9 are installed on the inner side of the straight slot 9. The sliding pins 10 are fixedly connected to the movable rod 7.

[0024] When the movable hook 4 does not need to be released, the control component makes the one-way movable component as a whole in the lowest stroke state, the sliding pin 10 on the upper side of the movable rod 7 abuts against the uppermost side of the straight slot 9, and the movable hook 4 is in a horizontal state. When the movable hook 4 needs to be rotated upward, the sliding pin 10 can slide downward inside the straight slot 9.

[0025] The cooperation between the sliding pin 10 and the straight slot 9 enables the movable rod 7 to provide support for the movable hook 4 without affecting the upward rotation of the movable hook 4, so that the one-way movable component has a clever structure, saves space and enhances stability.

[0026] The control component is installed on the inner side of the frame 3, and the control component includes two triangular plates 11, which are symmetrically distributed on the left and right sides of the frame 3 and hinged to the left and right sides. The lower side of the triangular plates 11 is hinged to the top rod 8, and a worm gear 17 is rotatably installed in the middle of the frame 3. Two rotating shafts 12 are symmetrically distributed on the left and right sides of the worm gear 17, and both rotating shafts 12 are hinged with a connecting rod 13. The connecting rod 13 on the left side is transmission-connected to the side of the triangular plate 11 on the left side, and the connecting rod 13 on the right side is transmission-connected to the side of the triangular plate 11 on the right side. A worm 14 matching it is rotatably installed on the side of the worm gear 17, and a motor 15 is installed on the upper side of the frame 3, and the output end of the motor 15 is transmission-connected to the worm 14.

[0027] When the automatic hook device needs to be hoisted, the rotating shafts 12 on the left and right sides of the worm gear 17 are in a horizontal state. At this time, the connecting rod 13 is in the outermost stroke, and the triangular plate 11 is used to link the connecting rod 13 with the top rod 8. At this time, the entire one-way movable assembly is in the lowest stroke, and the movable hook 4 is in a horizontal state. When it is necessary to release the items hoisted by the automatic hook device, the control motor 15 rotates, and the worm 14 drives the worm gear 17 to change the position of the two rotating shafts 12. At this time, the connecting rod 13 moves to the middle, and the triangular plate 11 moves the entire one-way movable assembly upward, so that the movable hook 4 can rotate downward, and the items hoisted on the lower side of the movable hook 4 can be released.

[0028] The cooperation of the worm gear 17 and the worm 14 enables the control component to have the characteristics of a large transmission ratio and a compact structure while controlling the lifting and release of the movable hook 4. When the motor 15 stops working, the worm gear 17 and the worm 14 can be locked in one direction, so that it can withstand large radial and axial loads, thereby improving the stability of the control component.

[0029] The steel ropes 2 are in two groups and are linearly distributed left and right.

[0030] The two sets of steel wire ropes linearly distributed on the left and right sides can enable the drone body 1 to better control the direction of the automatic hook device, so that it can more conveniently hang the lifting buckle 6, thereby improving the convenience of operation.

[0031] A plurality of triangular through slots 16 are formed on the sides of the frame 3 and the movable hook 4 .

[0032] The hollow design of the triangular through slot 16 can effectively reduce the overall weight of the automatic hook device, reduce production costs, and at the same time enhance the strength and stability of the structure, increase its wind resistance, and improve the reliability of the automatic hook device.

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
