Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) transportation technology, and in particular to a high-payload transport UAV. Background Technology

[0002] A cargo transport drone is an unmanned aerial vehicle primarily used for transporting goods. It combines drone technology with cargo-carrying capabilities, representing an emerging tool in modern logistics and transportation. To achieve cargo transport, cargo transport drones are equipped with specialized cargo-carrying devices. These include hooks for attaching cargo, clamping devices for lifting cargo, or cargo holds.

[0003] However, in existing technologies, heavy objects are prone to swaying and shifting in the air during high-load transportation, especially when transporting drones. In particular, when traditional transportation methods are used to hoist heavy objects, the connection between the heavy object and the transport vehicle (such as ropes) may cause the heavy object to swing significantly due to various factors such as airflow and changes in flight attitude, thereby affecting the payload of the drone and posing certain safety hazards during transportation. Utility Model Content

[0004] This utility model mainly provides a carrier drone with stable positioning and compact space.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-load-bearing transport drone, comprising a drone body, two fixed plates fixedly connected to the bottom end of the drone body, two half-gears rotatably connected to the inner sidewall of the fixed plates, the two half-gears meshing with each other, a swing rod one fixedly connected to the axis of the half-gears, a swing rod two rotatably connected to the bottom end of the fixed plates, a linkage rod connecting the swing rod one and the swing rod two, a clamping frame rotatably connected to the bottom end of the linkage rod, a power shaft provided below the bottom end of the drone body, a take-up roller provided on the outer side wall of the power shaft, a rope wound around the outer periphery of the take-up roller, and a hook fixedly connected to the tail end of the rope, and both ends of the power shaft movably connected to the half-gears.

[0006] Preferably, a retaining sleeve is fixedly connected to the top surface of the drone body. One end of the rope passes through the retaining sleeve and is fixedly connected to the hook. The retaining sleeve is suspended below the drone body by a connecting frame. The retaining sleeve is conical in shape, and its lower opening has a small diameter, which can effectively limit the hook.

[0007] Preferably, the bottom of the UAV body is fixedly connected to a positioning seat, and the power shaft is rotatably connected to the inner side wall of the positioning seat. Positioning seats are provided on both sides of the take-up roller. The two positioning seats position the power shaft. The principle of determining a straight line by two points ensures the stability of the movement axis position of the power shaft.

[0008] Preferably, the power shaft includes a movable shaft, a first side shaft, and a second side shaft. The power shaft adopts a split structure design. A gear set is installed on the outer side wall of the movable shaft. The servo motor is located inside the power compartment, so that the servo motor controls the rotation of the movable shaft, and the position of the movable shaft controls the rotation of the first side shaft or the second side shaft.

[0009] Preferably, both ends of the movable shaft are fixedly connected to pins, and one end of the first side shaft and the second side shaft are provided with pin grooves corresponding to the shape of the pins. The pins are externally hexagonal and have corresponding internally hexagonal pin grooves, so that the movable shaft can be controlled to cooperate with the first side shaft or the second side shaft through the pins.

[0010] Preferably, the first side shaft is fixedly connected to the take-up roller, and the pin is fixedly connected to the half gear. When the movable shaft moves to the right, the movable shaft rotates at the same speed as the side shaft through the pin, causing the first side shaft to drive the take-up roller to rotate and take up the rope. Conversely, the second side shaft can drive the half gear to rotate and clamp the weight.

[0011] Preferably, propellers are installed at the four corners of the top of the drone body, and a power compartment is set at the center of the bottom surface of the drone body. The power compartment is also connected to an electromagnet, which controls the position of the movable shaft, so that it moves in the left and right directions and controls the connection status with side shaft one and side shaft two.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the dual positioning method of hooking the top of the heavy object and two clamping frames supporting the bottom of the heavy object allows the heavy object to be firmly fixed to the lower surface of the drone body in the air. The hook lifting is controlled by rotating the take-up roller to control the rope, which can gradually bring the heavy object and the drone body closer together, reduce the length of the connecting rope between the two, thereby effectively reducing the swing amplitude of the heavy object and making the position of the heavy object in the air more stable. This is conducive to precise transportation and coping with complex aerial flight environments, forming a whole and effectively avoiding safety problems such as the heavy object falling or detaching during transportation, greatly improving the safety and reliability of transportation.

[0014] 2. In this utility model, the clamping frame and hook both achieve the fixing effect of heavy objects by means of the power shaft, which reduces the number of control parts and the space occupied. By changing the position of the movable shaft, the side shaft one or side shaft two can be driven to rotate as needed, realizing the precise switching of different actions such as the take-up roller taking up the rope and the half gear clamping the heavy object. This reduces the overall weight, optimizes the structure of the drone itself, and can better meet the needs of high-load transportation, thereby improving the drone's load capacity and flight performance.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figure 1 - Figure 4This utility model provides a high-payload transport drone, including a drone body 1. Two fixed plates 10 are fixedly connected to the bottom of the drone body 1. Two half-gears 11 are rotatably connected to the inner sidewalls of the fixed plates 10, and the two half-gears 11 mesh with each other. A swing rod 12 is fixedly connected to the axis of the half-gears 11. A second swing rod 13 is rotatably connected to the bottom of the fixed plates 10. A linkage rod 14 is connected between the first swing rod 12 and the second swing rod 13. A clamping frame 4 is rotatably connected to the bottom of the linkage rod 14. A moving part is provided below the bottom of the drone body 1. The power shaft 8 has a take-up roller 9 on its outer wall. A rope is wound around the outer periphery of the take-up roller 9, and the end of the rope is fixedly connected to a hook 5. Both ends of the power shaft 8 are movably connected to half-gears 11. For high-load transport using a drone, the hook 5 is used to hoist the top of the heavy object, and two clamping frames 4 are used to lift the bottom of the heavy object upwards, providing double positioning and ensuring the heavy object is firmly fixed to the lower surface of the drone body 1 in the air, forming a single unit with the drone body 1 and preventing the heavy object from falling or detaching. Regarding issues such as separation, the lifting of hook 5 is controlled by rotating the take-up roller 9, which drives the power shaft 8 to select the take-up roller 9. This causes the take-up roller 9 to wrap the rope around its outer perimeter, allowing hook 5 to lift the weight gradually until hook 5 pulls the weight between the two clamping frames 4. By reducing the length of the rope connecting the drone body 1 and the weight, the swing amplitude of the weight is reduced, making the position of the weight more stable. The clamping of the two clamping frames 4 is controlled by rotating the half gear 11, which causes the take-up roller 9 to drive one of the half gears 11 to rotate, thereby causing the two half gears to lift the weight. Gear 11 rotates in opposite directions, causing the two swing rods 12 to clamp towards the middle. Since the swing rods 12 and 13 are driven by the linkage rod 14, they form a parallelogram structure, which causes the linkage rod 14 to move the clamping frame 4 connected at the bottom to the middle. After the clamping frames 4 on both sides move towards the middle, their distance decreases, thus enabling the weight to be lifted from both sides towards the middle. The clamping frame 4 and the hook 5 fix the weight to the weight through the power shaft 8, which reduces the space and weight of the control parts and meets the cargo transportation needs of the UAV.

[0023] like Figure 2 As shown, a retaining sleeve 6 is fixedly connected to the top surface of the drone body 1. One end of the rope passes through the retaining sleeve 6 and is fixedly connected to the hook 5. The retaining sleeve 6 is suspended below the drone body 1 by a connecting frame. The retaining sleeve 6 is conical in shape, and its lower opening has a small diameter, which can effectively limit the hook 5.

[0024] like Figure 2 As shown, the bottom of the UAV body 1 is fixedly connected to the positioning seat 7, and the power shaft 8 is rotatably connected to the inner wall of the positioning seat 7. Positioning seats 7 are set on both sides of the take-up roller 9. The two positioning seats 7 position the power shaft 8. The principle of determining the straight line by two points ensures the stability of the movement axis position of the power shaft 8.

[0025] like Figure 4 As shown, the power shaft 8 includes a movable shaft 81, a first side shaft 82, and a second side shaft 83. The power shaft 8 adopts a split structure design. A gear set is installed on the outer side wall of the movable shaft 81. The servo motor is located inside the power chamber 3, which controls the rotation of the movable shaft 81. The position of the movable shaft 81 then controls the rotation of the first side shaft 82 or the second side shaft 83.

[0026] like Figure 4 As shown, both ends of the movable shaft 81 are fixedly connected to pins 84. One end of the side shaft 82 and the side shaft 83 are provided with pin grooves corresponding to the shape of the pins 84. The pins 84 are external hexagonal and have corresponding internal hexagonal pin grooves, so that the movable shaft 81 can be controlled to cooperate with the side shaft 82 or the side shaft 83 through the pins 84.

[0027] like Figure 2 As shown, side shaft 82 is fixedly connected to take-up roller 9, and pin 84 is fixedly connected to half gear 11. When the movable shaft 81 moves to the right, the movable shaft 81 rotates at the same speed as side shaft 82 through pin 84, causing side shaft 82 to drive take-up roller 9 to rotate and take up the rope. Conversely, side shaft 83 can drive half gear 11 to rotate and clamp the weight.

[0028] like Figure 1 As shown, propellers 2 are installed at the four corners of the top of the drone body 1. A power chamber 3 is set at the center of the bottom surface of the drone body 1. The power chamber 3 is also connected to an electromagnet. The electromagnet controls the position of the movable shaft 81, so that it moves in the left and right directions, and controls the connection status with the side shaft 1 82 and the side shaft 2 83.

[0029] The usage and working principle of this device are as follows: First, the servo motor in the power chamber 3 controls the rotation of the movable shaft 81, and the electromagnet controls the movable shaft 81 to move to the right. It rotates at the same speed as the side shaft 82 through the pin head 84. The side shaft 82 drives the take-up roller 9 to rotate. The take-up roller 9 takes up the rope, and the hook 5 lifts the heavy object and gradually raises it until the heavy object is pulled between the two clamping frames 4. This reduces the length of the rope connecting the drone and the heavy object, reduces the swing amplitude of the heavy object, and makes the position more stable.

[0030] Then, the movable shaft 81 moves to the left, which causes the side shaft 2 83 to drive the half gear 11 to rotate, causing one of the half gears 11 to rotate. Since the two half gears 11 mesh with each other and rotate in opposite directions, the two swing rods 12 clamp towards the middle. Since the swing rods 12 and 13 are connected by the linkage rod 14 to form a parallelogram structure, the linkage rod 14 drives the bottom clamping frame 4 to move towards the middle, lifting the bottom sides of the heavy object towards the middle, forming a double positioning of the heavy object with the hook 5, so that the heavy object is firmly fixed to the lower surface of the drone body 1, preventing it from falling or falling off.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
