Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a logistics UAV with a stable, high-degree-of-freedom cargo hold. Background Technology
[0002] As one of the most popular fields in recent years, drones are increasingly used in various industries, including aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news, and logistics. Drones used in logistics often have storage compartments installed on the underside of the fuselage. Items to be transported are placed in the storage compartment, and then the drone is controlled to deliver them to the designated location, which greatly saves manpower. However, existing logistics drones lack fixed devices inside the cargo compartment, causing the cargo to roll inside during speed changes and ascents and descents, affecting the drone's flight. In addition, some weighted but slender items cannot be packed into the cargo compartment and cannot be transported, which urgently needs improvement. Utility Model Content
[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a logistics drone with a stable, high-degree-of-freedom cargo hold, comprising a drone body and a cargo hold. The cargo hold is located at the bottom of the drone body and includes a tubular cargo body and a pair of doors matching the cargo body. The pair of doors are rotatably connected to two openings of the cargo body. The cargo hold is equipped with a limiting device for fixing goods during transportation. The limiting device includes a protective net, a pair of mounting rods, several sliding rods, a pair of control rods, and a limiting mechanism. The pair of control rods are fixedly mounted on the pair of mounting rods. The two ends of the protective net are connected to the pair of mounting rods. A pair of adjusting grooves matching the control rods are symmetrically opened on the two side walls of the cargo body. The pair of control rods are all located within the adjusting grooves. The several sliding rods are all located near the corners of the cargo hold. The pair of mounting rods are located between the inner wall of the cargo hold and the sliding rods. The limiting mechanism is located on the pair of control rods.
[0004] By adopting the above technical solution, a limiting device including a protective net, a pair of mounting rods, several sliding rods, a pair of control rods, and a limiting mechanism is installed in the cargo warehouse. After the goods are transported and placed into the cargo warehouse, the pair of control rods are slid downwards to allow the protective net to wrap around the goods. Then, the limiting mechanism is used to fix the control rods, thus securing the goods in the cargo warehouse. In this way, when the drone is flying, the goods will not roll around in the cargo warehouse and affect the normal flight of the drone.
[0005] Further features of this invention: The limiting mechanism includes a pair of limiting rings and a pair of control knobs that match the control rods. Both the pair of limiting rings and the pair of control rods are threaded. The pair of limiting rings are respectively connected to the pair of control rods by threads. The pair of control knobs are respectively set on the pair of limiting rings. The pair of adjusting slides have several limiting grooves that match the limiting rings.
[0006] By adopting the above technical solution, the limiting mechanism includes a pair of limiting rings and a pair of control knobs that match the control rod. Both the pair of limiting rings and the pair of control rods are provided with threads. The pair of limiting rings are respectively connected to the pair of control rods by threads. The pair of control knobs are respectively set on the pair of limiting rings. The pair of adjusting slides have several limiting grooves that match the limiting rings. When the control rod slides to the position of the corresponding limiting groove, the control knob is rotated to rotate the limiting ring into the limiting groove, thereby completing the limiting of the control rod.
[0007] A further feature of this invention is that each of the pair of compartment doors has an arc-shaped notch at the same position at its bottom, and a rotary motor is provided at the opening on each compartment body, with the compartment door connected to the shaft of the rotary motor.
[0008] By adopting the above technical solution, since the bottom of the pair of compartment doors is opened at the same position, and a rotary motor is installed at the opening of each compartment body, and the compartment door is connected to the rotating shaft of the rotary motor, when it is necessary to transport long and narrow goods, the two ends of the goods are stuck in the arc-shaped notches of the pair of compartment doors, and then the rotary motor is started to control the compartment doors to press down and clamp the two ends of the goods. In this way, the long and narrow goods can be fixed in the cargo compartment.
[0009] A further feature of this invention is that each of the arc-shaped notches is provided with a rubber protective sleeve.
[0010] By adopting the above technical solution, since each of the arc-shaped notches is equipped with a rubber protective sleeve, the surface of the goods can be protected from being pinched by the cargo door when the goods are secured. Attached Figure Description

Detailed Implementation
[0015] like Figure 1-3 As shown, a logistics drone with a stable, high-degree-of-freedom cargo hold includes a drone body 1 and a cargo hold 2. The cargo hold is located at the bottom of the drone body and includes a tubular cargo body and a pair of cargo doors 3 that match the cargo body. The pair of cargo doors are rotatably connected to two openings of the cargo body. The cargo hold is equipped with a limiting device 4 for fixing the cargo during transportation. The limiting device includes a protective net 5, a pair of mounting rods 6, several sliding rods 7, a pair of control rods 8, and a limiting mechanism 9. The pair of control rods are fixedly mounted on the pair of mounting rods. The two ends of the protective net are connected to the pair of mounting rods. A pair of adjusting grooves 10 that match the control rods are symmetrically opened on the two side walls of the cargo body. The pair of control rods are all located in the adjusting grooves. The several sliding rods are all located near the corners of the cargo hold. The pair of mounting rods are located between the inner wall of the cargo hold and the sliding rods. The limiting mechanism is located on the pair of control rods.
[0016] By installing a limiting device inside the cargo hold, including a protective net, a pair of mounting rods, several sliding rods, a pair of control rods, and a limiting mechanism, after the goods are transported and placed inside the cargo hold, the pair of control rods are slid downwards to allow the protective net to wrap around the goods. Then, the limiting mechanism is used to fix the control rods in place, thus securing the goods inside the cargo hold. This prevents the goods from rolling around inside the cargo hold and affecting the normal flight of the drone.
[0017] The limiting mechanism includes a pair of limiting rings 11 that match the control rods and a pair of control knobs 12. Both the pair of limiting rings and the pair of control rods are provided with threads. The pair of limiting rings are respectively connected to the pair of control rods by threads. The pair of control knobs are respectively set on the pair of limiting rings. The pair of adjusting slides have a plurality of limiting grooves 13 that match the limiting rings.
[0018] The limiting mechanism includes a pair of limiting rings and a pair of control knobs that match the control rods. Both the pair of limiting rings and the pair of control rods are threaded. The pair of limiting rings are respectively connected to the pair of control rods by threads. The pair of control knobs are respectively set on the pair of limiting rings. The pair of adjusting slides have several limiting grooves that match the limiting rings. When the control rod slides to the corresponding limiting groove position, the control knob is rotated to screw the limiting ring into the limiting groove, thus completing the limiting of the control rod.
[0019] The bottom of each pair of compartment doors has an arc-shaped notch 14 at the same position, and a rotary motor 15 is provided on each compartment body at the opening. The compartment doors are connected to the rotating shaft of the rotary motor.
[0020] Since the bottom of the pair of compartment doors is opened at the same position, and a rotary motor is installed at the opening of each compartment body, and the compartment door is connected to the rotating shaft of the rotary motor, when it is necessary to transport long and narrow goods, the two ends of the goods are stuck in the arc-shaped notches of the pair of compartment doors, and then the rotary motor is started to control the compartment doors to press down and clamp the two ends of the goods. In this way, long and narrow goods can be fixed in the cargo compartment.
[0021] Each of the arc-shaped notches is provided with a rubber protective sleeve 16.
[0022] Because each of the arc-shaped notches is equipped with a rubber protective sleeve, the surface of the goods can be protected from being pinched by the cargo door when the goods are secured.
