Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and more specifically, to an aluminum alloy skeleton assembly for an unmanned aerial vehicle. Background Art

[0002] An unmanned aerial vehicle is a device that is remotely controlled by radio and self - contained program control devices to achieve unmanned flight. Generally, a skeleton is provided on the unmanned aerial vehicle to play a supporting role. In addition, a supporting component is generally provided at the bottom of the skeleton so that the unmanned aerial vehicle can be supported on the ground by the supporting component to achieve stable placement.

[0003] At present, most of the supporting components at the bottom of the skeleton are generally made of rigid support rods, and there are no components that can buffer and shock - absorb. This is not conducive to buffer and shock - absorption protection operations when the unmanned aerial vehicle docks, and it will cause the unmanned aerial vehicle to collide with the ground when docking, affecting stability. There are also some unmanned aerial vehicles whose bottom supporting components use springs for shock absorption. However, due to the relatively light weight of the unmanned aerial vehicle, the extrusion force on the spring is small, and it is difficult to achieve a good shock - absorption effect by using springs. In view of this, we have proposed an aluminum alloy skeleton assembly for an unmanned aerial vehicle. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an aluminum alloy skeleton assembly for an unmanned aerial vehicle to solve the defects mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

Two symmetrically arranged front and rear support rods are fixedly installed on the bottom surface of the aluminum alloy skeleton main body. The cross - section of the support rod is in an inverted U - shape. Horizontal rods are fixedly installed at both ends of the support rod. An inner buffer sleeve is sleeved on the horizontal rod, and an outer buffer sleeve is sleeved outside the inner buffer sleeve. A plurality of groups of buffer rubber balls arranged in an annular and equidistant manner are fixedly installed between the inner buffer sleeve and the outer buffer sleeve. A wear - resistant layer is provided on the outer surface of the outer buffer sleeve.

[0007] Preferably, the buffer rubber ball is a hollow spherical shape for buffer protection operations.

[0008] Preferably, a limit ring is fixedly installed at the end of the horizontal rod close to the support rod for limiting the outer buffer sleeve.

[0009] Preferably, an end limit sleeve is sleeved on the rod body at the other end of the horizontal rod for anti - detachment protection of the outer buffer sleeve.

[0010] Preferably, a threaded sleeve is provided inside the end rod body of the horizontal rod, and the end limiting sleeve and the threaded sleeve are fixed by fastening screws, which facilitates the fixing operation of the end limiting sleeve.

A fixing ring is fixedly installed at the end of the threaded sleeve, and the fixing ring is fixedly installed on the end face of the horizontal rod by fastening screws, which facilitates the fixing operation of the threaded sleeve.

[0012] Preferably, the outer diameters of the limiting ring and the end limiting sleeve are both smaller than the outer diameter of the inner buffer sleeve, and the outer diameters of the limiting ring and the end limiting sleeve are both larger than the inner diameter of the inner buffer sleeve, which has the effect of preventing the inner buffer sleeve from coming off and limiting it.

[0013] Preferably, the number of each group of buffer rubber balls is 10 to 20, and the distance between adjacent two groups of buffer rubber balls is 0.8 cm to 1.5 cm, which facilitates better buffer protection operation by using the buffer rubber balls.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 - 5 , the present invention provides a technical solution: an aluminum alloy skeleton assembly for a drone, including an aluminum alloy skeleton main body 1. The aluminum alloy skeleton main body 1 is made of aluminum alloy material as a whole. As a metal material, the aluminum alloy material has a relatively low conductivity and can shield electromagnetic waves to a certain extent, achieving the effect of electromagnetic shielding protection;

[0027] Specifically, two symmetrically arranged support rods 2 are fixedly installed on the bottom surface of the aluminum alloy skeleton main body 1. The cross-section of the support rod 2 is in an inverted U shape. Horizontal rods 20 are fixedly installed at both ends of the support rod 2. An inner buffer sleeve 22 is sleeved on the horizontal rod 20, and an outer buffer sleeve 23 is sleeved outside the inner buffer sleeve 22. A plurality of groups of buffer rubber balls 24 arranged in an annular and equally spaced manner are fixedly installed between the inner buffer sleeve 22 and the outer buffer sleeve 23. The buffer rubber balls 24 are hollow spherical and are used for buffer protection operations; the number of each group of buffer rubber balls 24 is 10 - 20, and the distance between adjacent two groups of buffer rubber balls 24 is 0.8 cm - 1.5 cm, which is convenient for using the buffer rubber balls 24 for better buffer protection operations. Moreover, the inner buffer sleeve 22 and the outer buffer sleeve 23 can be made of foam sponge material. The foam sponge material is light in texture and soft, and can achieve a better shock absorption and buffer protection effect.

[0028] In this embodiment, a wear-resistant layer 25 is provided on the outer surface of the outer buffer sleeve 23. The wear-resistant layer 25 can be made by spraying wear-resistant particulate material to improve the wear resistance and is beneficial to extending the service life.

[0029] Specifically, a limit ring 201 is fixedly installed at the end of the horizontal rod 20 close to the support rod 2. The limit ring 201 is used for limiting the outer buffer sleeve 23.

[0030] Furthermore, an end limit sleeve 26 is sleeved on the rod body at the other end of the horizontal rod 20, and the end limit sleeve 26 is used for the anti-disconnection protection operation of the outer buffer sleeve 23.

[0031] In addition, a threaded sleeve 21 is arranged inside the end rod body of the horizontal rod 20, and the end limit sleeve 26 and the threaded sleeve 21 are fixed by a fastening screw 27, which is convenient for the fixing operation of the end limit sleeve 26.

[0032] It should be noted that an annular groove 202 is arranged inside the end rod body of the horizontal rod 20, and the threaded sleeve 21 is in plug-in fit with the annular groove 202. A fixing ring 211 is fixedly installed at the end of the threaded sleeve 21, and the fixing ring 211 is fixedly installed on the end face of the horizontal rod 20 by a fastening screw, which is convenient for the fixing operation of the threaded sleeve 21. And after the internal thread in the threaded sleeve 21 is stripped, the threaded sleeve 21 can be disassembled and replaced.

[0033] It should be noted that the outer diameters of the limit ring 201 and the end limit sleeve 26 are both smaller than the outer diameter of the inner buffer sleeve 22, and the outer diameters of the limit ring 201 and the end limit sleeve 26 are both larger than the inner diameter of the inner buffer sleeve 22, which has the effect of preventing the inner buffer sleeve 22 from disconnecting and limiting its position.

[0034] When the UAV aluminum alloy skeleton assembly of the present invention is in use, the inner buffer sleeve 22 is sleeved on the horizontal rod 20, then the end limit sleeve 26 is sleeved on the horizontal rod 20, and the end limit sleeve 26 and the threaded sleeve 21 are fixed by a fastening screw 27 to complete the fixing operation. When the UAV docks later, the outer buffer sleeve 23 supports on the ground, and the outer buffer sleeve 23, the inner buffer sleeve 22 and the buffer rubber ball 24 achieve shock absorption and buffer protection.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
