Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) transportation, in particular to a UAV lifting device. Background Art

[0002] In the current logistics and transportation industry, delivery terminals are usually manually delivered individually, especially in the express delivery industry. Couriers usually manually plan routes based on various factors such as the delivery location, delivery quantity, and delivery road conditions of the package, in order to achieve labor-saving and fast delivery effects. Due to the characteristics of drones, the cargo racks used by cargo drones to lift goods usually have weight requirements to increase the effective load. At present, closed cargo boxes have high deadweight and small effective load capacity, while open cargo racks have relatively large effective load capacity, but their shape is fixed, so they cannot be flexibly adapted to the size and shape of terminal goods. When using cargo drones for transportation, additional manual fixation is often required. Manual fixation may not be firm enough, causing the goods to loosen and cause objects to be thrown from high altitude. At the same time, when the drone lands, the drone loaded with goods is relatively heavy, and the impact force generated when landing is greater than before, which can easily cause damage to the drone during landing. In addition, the goods are hoisted at the bottom, and protrusions on the ground during landing can easily cause direct impact damage to the goods, resulting in certain economic losses.

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0024] An embodiment of the present application provides a drone lifting device, which can adjust the size of the loading platform according to the actual size of the goods through an adjustment component, so that goods of different sizes can be loaded and fixed, thereby improving the practical performance of the device, and does not require manual secondary fixing, has high stability, and avoids the safety risk of throwing objects from high places.

[0025] The following is a detailed description of the UAV lifting device. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0026] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] Example 1

[0028] See also Figure 1-8 In this embodiment, a drone lifting device is provided, including: a drone body 1, a frame 11 is fixedly connected to the bottom of the drone body 1, two splints 12 are provided inside the frame 11, and the bottom of the two splints 12 are respectively provided with symmetrically arranged grab plates 13, an adjustment component, the adjustment component is respectively provided on the two splints 12, for adjusting the height position of the grab plates 13, the adjustment component includes: a storage cavity 2, a threaded screw 21, a limit block 22 and an adjustment block 23, a buffer component, the buffer component is provided at the bottom of the two splints 12, for providing buffering during landing, and the buffer component includes: a sleeve 3, a limit rod 31, a support block 32, a damper 33 and a spring 34.

[0029] When in use, the cargo is placed between the two splints 12, which clamp the cargo and use the grab plate 13 to support the bottom of the cargo to fix the cargo. The height of the grab plate 13 can be adjusted by adjusting the component to adapt to cargo of different thicknesses. With the two movable splints 12, cargo of different sizes can be dropped and taken, and the buffer component provides buffering when the cargo is transported to the destination and landed, so as to avoid the gravity of the cargo causing a large impact and damaging the drone.

[0030] Example 2

[0031] On the basis of Example 1, a storage cavity 2 is respectively opened near the middle position at the bottom of the two splints 12, and a threaded screw 21 is slidably connected inside the storage cavity 2. The bottom end of the threaded screw 21 is connected to the grab plate 13, and the top of the threaded screw 21 is fixedly connected to the limiting block 22. The two splints 12 are rotatably connected with an adjustment block 23 near the bottom end of the storage cavity 2. The adjustment block 23 is threadedly connected to the outside of the threaded screw 21. Guide cavities 24 are respectively provided at the two sides of the bottom of the two splints 12 away from the storage cavity 2. Guide rods 25 are slidably connected inside the guide cavity 24, and the bottom end of the guide rod 25 is connected to the splint 12.

[0032] When adjusting the height of the grab plate 13, the adjustment block 23 is manually rotated to engage with the threaded screw 21. Since the grab plate 13 is restricted by the guide rod 25 and the guide cavity 24, the grab plate 13 cannot be rotated and can only move along the vertical direction of the guide cavity 24. Therefore, when the thread is screwed, the grab plate 13 will be driven to move in the vertical direction. By controlling the direction of rotating the adjustment block 23, the grab plate 13 can be controlled to move upward or downward, thereby adjusting the distance between the grab plate 13 and the drone body 1, so that it can grab goods of different thicknesses.

[0033] Example 3

[0034] On the basis of Example 1, a bidirectional threaded screw 4 is rotatably connected to the inside of the frame 11, and the two splints 12 are respectively threadedly connected to the two sections of the thread of the bidirectional threaded screw 4. A protective cover 41 is fixedly connected to one side of the frame 11. One end of the bidirectional threaded screw 4 passes through the frame 11 and extends to the inside of the protective cover 41 and is fixedly connected to a driven gear 42. An installation cavity 43 is provided inside the drone body 1, and a servo motor 44 is fixedly installed inside the installation cavity 43. One end of the drive shaft of the servo motor 44 is drivingly connected to a driving gear 45. The driving gear 45 and the driven gear 42 are connected by a hinge transmission, and a through groove for the hinge to pass through is provided between the installation cavity 43 and the protective cover 41. Fixed rods 46 are respectively fixedly connected to the two sides of the inner wall of the frame 11 away from the bidirectional threaded screw 4, and through holes for the two fixing rods 46 to pass through are respectively provided on the two splints 12. The two splints 12 are slidably connected to the outside of the two fixing rods 46 through the two through holes.

[0035] When it is necessary to clamp the goods, the servo motor 44 is controlled to drive the driving gear 45 to rotate, and the driving gear 45 drives the driven gear 42 to rotate through the hinge, and the driven gear 42 drives the bidirectional threaded screw 4, and the bidirectional threaded screw 4 rotates and screws with the two clamps 12. Since the clamps 12 are restricted by the frame 11 and the two fixing rods 46, the two clamps 12 can only move in the horizontal direction, and the two clamps 12 are respectively located on two sections of threads in opposite directions. Therefore, when screwed with the bidirectional threaded screw 4, the two clamps 12 will be driven to move relative to each other. By controlling the rotation direction of the bidirectional threaded screw 4, the clamps 12 can be controlled to move closer and apart, so that the goods can be clamped, so that goods of different widths can be fixed.

[0036] Example 4

[0037] On the basis of Example 1, two sleeves 3 are fixedly connected to the bottom of the two splints 12 respectively, and a limiting rod 31 is slidably connected inside the sleeve 3. The bottom end of the limiting rod 31 is fixedly connected to the support block 32, and the top of the sleeve 3 is fixedly connected to the damper 33. The bottom end of the damper 33 is connected to the limiting rod 31, and a spring 34 is provided on the outside of the damper 33. The top of the spring 34 is connected to the top of the sleeve 3, and the bottom end of the spring 34 is connected to the top of the limiting rod 31.

[0038] When the drone body 1 loaded with cargo lands, the support block 32 contacts the ground first, and the drone body 1 moves downward under the influence of gravity, so that the limit rod 31 is inside the sleeve 3. When the limit rod 31 retracts, it squeezes the damper 33 and the spring 34. The damper 33 absorbs and offsets the impact force, and cooperates with the spring 34 to return and further buffer the impact force. In this way, the drone body 1 loaded with cargo can minimize the impact of the impact force when landing, thereby avoiding damage to the drone body 1.

[0039] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
