Description

Technical Field

[0001] The utility model is applicable to the technical field of unmanned aerial vehicles, and particularly relates to an air-dropping device with adaptive deceleration. Background Art

[0002] In recent years, swarm unmanned aerial vehicles are often placed in the dropping cabin of an air-dropping device to be dropped to a specific area to perform tasks. The working process is as follows: the dropping cabin is dropped, the speed reducer is deployed at a certain height, after the dropping cabin decelerates and lands to meet a certain speed and height, the unmanned aerial vehicle in the cabin exits the cabin, and the unmanned aerial vehicle cruises to complete the dropping.

[0003] However, the speed reducers of the existing dropping cabins are all rigidly connected, that is, fixed at a certain angle. During the landing process of the dropping cabin, as the speed increases, the resistance received by the speed reducer also increases, and the overload received by the equipment and the unmanned aerial vehicle in the dropping cabin also increases. And large overload may cause a series of problems such as equipment power-off, mechanical damage to equipment, and damage to electronic equipment.

[0004] Therefore, there is an urgent need for an air-dropping device with adaptive deceleration to solve the above problems. Summary of the Utility Model

The air-dropping device includes a dropping cabin in a hollow column shape and a plurality of deceleration components fixed to one end of the dropping cabin. The plurality of deceleration components are arranged at intervals in the circumferential direction of the outer periphery of the dropping cabin.

[0007] The deceleration component includes a speed reducer fixing member fixed to the outer periphery of the dropping cabin, a rotating shaft fixed to the side of the speed reducer fixing member away from the dropping cabin and perpendicular to the axial direction of the dropping cabin, a speed reducer plate rotatably connected to the rotating shaft and extending radially outward from the dropping cabin, a torsion spring wound around the rotating shaft, two first torsion spring fixing members fixed to opposite sides of the speed reducer fixing member, and two second torsion spring fixing members fixed to opposite sides of the end of the speed reducer plate close to the speed reducer fixing member. One end of the torsion spring is connected to the first torsion spring fixing member, and the other end of the torsion spring is connected to the second torsion spring fixing member.

Detailed Embodiments

[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] It should be noted that in this text, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising that element.

[0021] Please refer to Figures 1 - 3 , the present utility model provides an air-dropping device 100 with adaptive deceleration. The air-dropping device 100 includes a delivery cabin 1 in the shape of a hollow column and a plurality of deceleration components 2 fixed to one end of the delivery cabin 1. The plurality of deceleration components 2 are arranged at intervals in the circumferential direction along the outer circumference of the delivery cabin 1. The delivery cabin 1 is used to accommodate a drone (not marked in the figure);

[0022] The deceleration component 2 includes a deceleration plate fixing member 21 fixed to the outer circumference of the delivery cabin 1, a rotating shaft 23 fixed to the side of the deceleration plate fixing member 21 away from the delivery cabin 1 and perpendicular to the axial direction of the delivery cabin 1, a deceleration plate 22 rotatably connected to the rotating shaft 23 and extending outward in the radial direction of the delivery cabin 1, a torsion spring 24 wound around the rotating shaft 23, two first torsion spring fixing members 25 fixed to opposite sides of the deceleration plate fixing member 21, and two second torsion spring fixing members 26 fixed to opposite sides of the end of the deceleration plate 22 close to the deceleration plate fixing member 21. One end of the torsion spring 24 is connected to the first torsion spring fixing member 25, and the other end of the torsion spring 24 is connected to the second torsion spring fixing member 26. The torsion spring 24 is used to provide torsion for the unfolding of the deceleration plate 22.

[0023] Exemplarily, after the air-dropping device 100 is dropped, as the height decreases and the speed increases, the deceleration plate 22 unfolds after reaching a certain height. Until the initial speed reaches the maximum, the aerodynamic resistance received by the deceleration plate 22 is greater than the torsion of the torsion spring 24, prompting the deceleration plate 22 to fold backward, reducing the aerodynamic resistance and the overload accordingly. As the speed of the delivery cabin 1 decreases, the aerodynamic resistance received is less than the torsion of the torsion spring 24, and the deceleration plate 22 folds back to its original angle, thereby achieving adaptive speed reduction, effectively reducing the overload suffered by the equipment inside the delivery cabin 1 of the air-dropping device 100 and the drone, and further protecting the drone and equipment inside the delivery cabin 1.

[0024] In this embodiment, the second torsion spring fixing member 26 is fixed to the side of the deceleration plate 22 away from the first torsion spring fixing member 25, thereby effectively offsetting the aerodynamic resistance received by the deceleration plate 22 and the torsion provided by the torsion spring 24 to control the descending speed of the air-dropping device 100.

[0025] In this embodiment, the spoiler 22 is rectangular, and the spoiler 22 forms a 90° angle with the delivery pod 1, so that the aerodynamic drag received by the spoiler 22 is maximized at the beginning, thereby better reducing the speed of the delivery pod 1 during the delivery process.

[0026] In this embodiment, the delivery pod 1 is in a hollow cylindrical shape.

[0027] In this embodiment, the deceleration assembly 2 includes three and is arranged at equal intervals on the outer peripheral side of one end of the delivery pod 1. It should be noted that other numbers of deceleration assemblies 2 are also feasible.

[0028] Compared with the prior art, the aerial delivery device provided by the present utility model includes a hollow delivery pod and a plurality of deceleration assemblies fixedly arranged at one end of the delivery pod at intervals. The delivery pod is used to accommodate a drone; the deceleration assembly includes a spoiler fixing member fixed to one end of the delivery pod, a rotating shaft fixed to the side of the spoiler fixing member away from the delivery pod, and a spoiler rotatably connected to the rotating shaft. By arranging a torsion spring at the rotating shaft of the spoiler in the present utility model, the spoiler can change the rotation angle according to the wind resistance, thereby changing the overall overload suffered by the equipment in the delivery pod, reducing the damage of the equipment in the delivery pod, and playing a role in protecting the equipment in the pod.

[0029] The embodiments of the present utility model have been described above in conjunction with the accompanying drawings. What is disclosed is only the preferred embodiments of the present utility model. However, the present utility model is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present utility model, those of ordinary skill in the art can also make many equivalent changes in form without departing from the purpose and scope protected by the claims of the present utility model, and all of them fall within the protection scope of the present utility model.
