A sling for unmanned aerial vehicle to transport goods

Abstract

This utility model relates to the field of unmanned aerial vehicle (UAV) transportation technology and discloses a lifting device for transporting goods using a UAV. The device includes a UAV body, a lifting assembly installed inside a mounting box, and a loading assembly at the bottom of the lifting assembly. This UAV cargo lifting device is driven by a stepper motor to rotate a transmission rod. When the transmission rod rotates, it causes a first rotating roller to rotate synchronously, thereby automatically unwinding and rewinding the steel cable wound on it. Simultaneously, the rotation of the transmission rod also drives a first pulley to rotate, which, through a belt connection, drives a second pulley to rotate, causing a second rotating roller to rotate synchronously. This allows the steel cable on the second rotating roller to also be unwound and rewound synchronously. Each of the first and second rotating rollers has two steel cables. This component design increases the stability and reliability of the lifting operation.

Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) transportation technology, specifically a lifting device for transporting goods by UAV. Background Technology

[0002] Drone transportation is a new logistics transportation model that uses unmanned aerial vehicles to transport goods from origin to destination. Leveraging the unique advantages of drones in flight, it breaks the spatial limitations of traditional ground transportation, bringing new development directions and application scenarios to the logistics industry. In remote areas or long-distance transportation scenarios, there is no need to lay roads or build infrastructure, which can reduce labor and operating costs. It can easily reach areas with inconvenient ground transportation, such as mountains, islands, and deserts, providing an efficient solution for the transportation of goods in these areas, such as delivering express packages in remote rural areas and transporting relief supplies to disaster areas.

[0003] The lifting device used when transporting goods by drone is a key device connecting the drone and the cargo. It is mainly used to safely and stably suspend and lift the cargo. Its design must take into account the requirements of load-bearing capacity, ease of loading and unloading, and safety. It is suitable for lifting goods with regular shape and sturdy packaging, such as boxes and barrels. It is commonly used for short-distance, light-load transportation. The installation position of the lifting device needs to be calculated to ensure that the center of gravity of the drone is stable after the cargo is suspended, so as to avoid loss of control due to the center of gravity shift during flight. Some high-end lifting devices are equipped with dynamic balancing systems that can adjust the position of the cargo in real time.

[0004] Existing technology publication CN217076689U patent document provides a lifting device for transporting goods by drones. This device uses a hook for lifting goods, which, under the lifting and guiding action of a positioning guide hook, engages with a limiting groove on a positioning base. This limits the rotation of the hook, restricting the rotation of the goods. Consequently, during drone delivery, the goods do not rotate, ensuring drone flight stability and improving delivery reliability. Furthermore, during the lifting process by the positioning guide hook, the positioning effect of the conical cavity and the guiding effect of the arc-shaped guide opening ensure the hook smoothly engages with the limiting groove, guaranteeing the reliability of the hook's engagement.

[0005] While the aforementioned prior art allows the drone cargo transport lifting device to engage with a positioning slot on a locating bracket via a hook, thus restricting the rotation of the cargo and preventing it from rotating during transport, thereby stabilizing the drone's flight and improving reliability, the lifting device in this patented technology uses the same single rope as commonly available lifting devices. This makes the cargo prone to swaying during the unwinding and rewinding of the rope. Furthermore, the single rope provides no safety feature; if it breaks, the cargo will inevitably fall and be damaged. Therefore, this lifting device significantly reduces stability and reliability. Consequently, we need a drone cargo transport lifting device. Utility Model Content

[0006] The purpose of this utility model is to provide a lifting device for transporting goods by drones, in order to solve the problem that the lifting device for transporting goods by drones in the above-mentioned background technology uses the same lifting device as common lifting devices on the market, which only uses a single rope for lifting. This makes it easy for the goods to sway during the unwinding and winding of the rope. Moreover, the single rope setting has no safety feature. If the rope breaks, the goods will inevitably fall and be damaged. Therefore, the lifting device greatly reduces the stability and reliability of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A lifting device for transporting goods by drone includes a drone body, a mounting box at the bottom of the drone body, a lifting assembly installed inside the mounting box, and a loading assembly at the bottom of the lifting assembly. The hoisting assembly includes a stepper motor. The output end of the stepper motor is detachably connected to a transmission rod via a coupling. A first rotating roller is rotatably connected to the outer wall of the transmission rod. A steel cable is fixedly installed on the outer wall of the first rotating roller. A first pulley is rotatably connected to the outer wall of the transmission rod. A belt is installed on the outer wall of the first pulley. A second pulley is rotatably connected to the inner wall of the belt. A second rotating roller is installed on one side of the second pulley. The loading assembly includes a storage box, the front of which is provided with a hinge, and a door is rotatably connected to one side of the hinge. A handle is fixedly connected to the front of the door. A rotating shaft is provided on the front of the storage box, and a buckle is rotatably connected inside the rotating shaft.

[0008] Preferably, the bottom of the drone body is fixedly connected to a support leg, and a dual-wing propeller is provided on one side of the drone body.

[0009] Preferably, the stepper motor forms a rotating structure with the first rotating roller via a transmission rod, and the steel cable is wound around the outer surface of the first rotating roller.

[0010] Preferably, the transmission rod forms a rotating structure with the belt via a first pulley, and one end of the transmission rod passes through the first pulley. The first pulley forms a rotating structure with the second pulley via the belt.

[0011] Preferably, the belt forms a rotating structure with the second pulley and the second rotating roller, and the shape and size of the second rotating roller match those of the first rotating roller.

[0012] Preferably, the storage box is connected to the door via a hinge to form a rotating structure, and the hinge is installed between the storage box and the door.

[0013] Preferably, the storage box has a rotating structure formed by a rotating shaft and a buckle, and the number of buckles is two.

[0014] Compared with the prior art, the beneficial effects of this utility model are: a lifting device for transporting goods by drone, First, this utility model includes a stepper motor, a transmission rod, a first rotating roller, a steel cable, a first pulley, a belt, a second pulley, and a second rotating roller. The stepper motor drives the transmission rod to rotate, which in turn causes the first rotating roller to rotate synchronously. This allows for automatic unwinding and rewinding of the steel cable wound on it. Simultaneously, the transmission rod also drives the first pulley to rotate, which, through the belt connection, drives the second pulley to rotate, thus causing the second rotating roller to rotate synchronously. This allows the steel cable on the second rotating roller to be unwound and rewound synchronously. The first and second rotating rollers each have two steel cables, for a total of four steel cables, which greatly increases the stability of the hoisting operation. This component enhances the stability and reliability of the hoisting process.

[0015] Secondly, this utility model includes a storage box, hinges, a box door, a handle, a rotating shaft, and a buckle. The storage box allows for convenient placement of items that are difficult to hang or valuable items. The hinges rotate to open and close the box door. When the box door is closed, the rotating shaft rotates to lock the door in place, preventing it from opening easily and increasing stability during transport. This component also allows for convenient placement of items that cannot be hung, enhancing its practicality. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The hoisting assembly 3 includes a stepper motor 301. The output end of the stepper motor 301 is detachably connected to a transmission rod 302 via a coupling. A first rotating roller 303 is rotatably connected to the outer wall of the transmission rod 302. A steel cable 304 is fixedly installed on the outer wall of the first rotating roller 303. A first pulley 305 is rotatably connected to the outer wall of the transmission rod 302. A belt 306 is installed on the outer wall of the first pulley 305. A second pulley 307 is rotatably connected to the inner wall of the belt 306. A second rotating roller 308 is installed on one side of the second pulley 307. The loading assembly 6 includes a storage box 601. A hinge 602 is provided on the front of the storage box 601, and a door 603 is rotatably connected to one side of the hinge 602. A handle 604 is fixedly connected to the front of the door 603. A rotating shaft 605 is provided on the front of the storage box 601, and a buckle 606 is rotatably connected inside the rotating shaft 605.

[0020] Through the above technical solution, the stepper motor 301 drives the transmission rod 302 to rotate, and when the transmission rod 302 rotates, the first rotating roller 303 rotates synchronously, thereby automatically unwinding and rewinding the steel cable 304 wound on it. At the same time, the transmission rod 302 also drives the first pulley 305 to rotate, and through the connection of the belt 306, it drives the second pulley 307 to rotate, thereby causing the second rotating roller 308 to rotate synchronously. In this way, the steel cable 304 on the second rotating roller 308 can also be unwound and rewound synchronously. The first rotating roller 303 and the second rotating roller 308 are each equipped with two steel cables 304, and the arrangement of a total of four steel cables 304 can greatly increase the stability of hoisting. The arrangement of this component can increase the stability of hoisting and improve reliability.

[0021] Specifically, the bottom of the drone body 1 is fixedly connected to a support leg 4, and a dual-wing propeller 5 is provided on one side of the drone body 1.

[0022] Through the above technical solution, the support leg 4 can provide stable support for the drone body 1 when it lands, while the dual propeller 5 can bring stronger flight capability to the drone body 1 and increase the lift of the drone body 1.

[0023] Specifically, the stepper motor 301 forms a rotating structure with the first rotating roller 303 through the transmission rod 302, and the steel cable 304 is wound around the outer surface of the first rotating roller 303.

[0024] Through the above technical solution, the stepper motor 301 drives the transmission rod 302 to rotate, and when the transmission rod 302 rotates, the first rotating roller 303 rotates synchronously, thereby automatically unwinding and rewinding the steel cable 304 wound on it. The first rotating roller 303 is equipped with two steel cables 304, which increases the stability of hoisting.

[0025] Specifically, the transmission rod 302 forms a rotating structure with the first pulley 305 and the belt 306, and one end of the transmission rod 302 is set through the first pulley 305. The first pulley 305 forms a rotating structure with the second pulley 307 through the belt 306.

[0026] Through the above technical solution, when the transmission rod 302 rotates, it can also drive the first pulley 305 to rotate. Through the connection of the belt 306, it can drive the second pulley 307 to rotate. The first pulley 305, the belt 306, and the second pulley 307 are combined to form a pulley group, which plays the role of transmitting power in the component.

[0027] Specifically, the belt 306 forms a rotating structure with the second pulley 307 and the second rotating roller 308, and the shape and size of the second rotating roller 308 match those of the first rotating roller 303.

[0028] Through the above technical solution, the rotation of the second pulley 307 enables the second rotating roller 308 to rotate, and the second rotating roller 308 is also equipped with two steel cables 304, which can greatly increase the stability and reliability of hoisting.

[0029] Specifically, the storage box 601 forms a rotating structure with the door 603 via a hinge 602, and the hinge 602 is installed between the storage box 601 and the door 603.

[0030] Through the above technical solution, the storage box 601 can conveniently place some items that are inconvenient to hang or relatively valuable items. The rotation of the hinge 602 can drive the box door 603 to rotate, thereby completing the opening and closing of the storage box 601.

[0031] Specifically, the storage box 601 forms a rotating structure with the buckle 606 via the rotating shaft 605, and there are two buckles 606.

[0032] With the above technical solution, when the box door 603 is closed, the rotation of the rotating shaft 605 causes the buckle 606 to rotate, which can lock and fix the closed box door 603, preventing it from opening arbitrarily and increasing stability during transportation.

[0033] Working principle: When using this drone to transport goods with a lifting device, firstly, after the drone body 1 flies to the location of the goods to be transported, the stepper motor 301 is started. The stepper motor 301 drives the transmission rod 302 to rotate, and the rotation of the transmission rod 302 causes the first pulley 305 to rotate. Then, through the connection of the belt 306, the second pulley 307 rotates, which drives the first rotating roller 303 and the second rotating roller 308 to rotate synchronously. This unwinds the steel cable 304, causing it to lower the storage box 601. After the storage box 601 is lowered to the ground, the buckle 606 can be turned by hand. The rotation of the rotating shaft 605 drives the buckle 606 to rotate. Then, the handle 604 is pulled down, and the door 603 is opened by the hinge 602, so that the items placed in the storage box 601 can be retrieved. This completes the entire work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit defined by the appended claims and their equivalents.
