The first wrapping body and the second wrapping body respectively cover a portion of the cover. The first wrapping body and the second wrapping body are respectively fixedly connected to the cover. There is a gap between the first wrapping body and the second wrapping body.

[0007] The buffer assembly includes a buffer layer, a first interlayer, and a second interlayer. The buffer layer is built into the cover and has an inner cavity. The buffer layer has a buffer layer periphery section and a buffer layer bottom section integrally formed with the buffer layer periphery section. The first interlayer is integrally formed with the buffer layer periphery section, and the second interlayer is integrally formed with the buffer layer bottom section.

Detailed Implementation

[0022] This utility model discloses an obstacle avoidance and buffer protection mechanism for unmanned aerial vehicles (UAVs). The following description, in conjunction with a preferred embodiment (Embodiment 1), is shown in the accompanying drawings. Figures 1 to 8 The specific embodiments of this utility model will be further described below.

[0023] See attached diagram. Figures 1 to 8 , Figures 1 to 5 The drone obstacle avoidance and buffer protection mechanisms are shown from different perspectives. Figures 6 to 8 The partial structures of the drone obstacle avoidance and buffer protection mechanism are shown respectively.

[0024] Example 1.

[0025] Preferably, the drone obstacle avoidance and buffer protection mechanism includes a cover assembly 100 and a buffer assembly 300, wherein the buffer assembly 300 is detachably embedded in the cover assembly 100, wherein:

[0026] The cover assembly 100 includes a cover 130 and a first wrapping body 110 and a second wrapping body 120 placed outside the cover 130. The first wrapping body 110 and the second wrapping body 120 respectively cover a portion of the cover 130. The first wrapping body 110 and the second wrapping body 120 are fixedly connected to the outer surface of different parts of the cover 130. There is a gap between the first wrapping body 110 and the second wrapping body 120, so that the first wrapping body 110 and the second wrapping body 120 are not adjacent to each other, so that when the first wrapping body 110 or the second wrapping body 120 is deformed by an external force impact, the deformation of one wrapping body will not interfere with the deformation of the other wrapping body, thereby effectively mitigating the impact of the external force.

[0027] The buffer assembly 300 includes a buffer layer 310, a first interlayer 320, and a second interlayer 330. The buffer layer 310 is built into the cover 130 and has an inner cavity 311. The buffer layer 310 has a peripheral section 312 and a bottom section 313 integrally formed with the peripheral section 312. The first interlayer 320 is integrally formed with the peripheral section 312, and the second interlayer 330 is integrally formed with the bottom section 313. This allows the ends of the UAV support legs (not shown in the figure) to be fully covered within the inner cavity 311 of the buffer layer, thereby enhancing the passive buffering capability of the UAV in high-risk operating environments.

[0028] It should be noted that the drone obstacle avoidance and buffer protection mechanism disclosed in this embodiment can be added to the end of the support legs of an existing drone as needed, thereby improving the passive buffering capability of the existing drone (especially when the active obstacle avoidance capability of the existing drone is insufficient for safe operation in high-risk working environments). At the same time, the drone obstacle avoidance and buffer protection mechanism disclosed in this embodiment can also be quickly separated from the end of the support legs of the existing drone, thereby achieving the purpose of on-demand installation.

[0029] The first interlayer 320 has a plurality of first interlayer cavities 321 spaced apart, and a first interlayer connecting part 322 is provided between two adjacent first interlayer cavities 321. The first interlayer connecting part 322 is integrally formed with the buffer layer periphery section 312. The first interlayer cavity 321 of the first interlayer 320 is set as a single layer in order to accommodate the thinner buffer layer periphery section 312.

[0030] The second interlayer 330 has a plurality of second interlayer cavities 331 spaced apart, and a second interlayer connecting part 332 is provided between two adjacent second interlayer cavities 331. The second interlayer connecting part 332 is integrally formed with the bottom section 313 of the buffer layer. The second interlayer cavities 331 of the second interlayer 330 are configured as double-layered to provide more adequate passive buffering capacity.

[0031] The cover assembly 100 and the cushioning assembly 300 are preferably made of elastic material.

[0032] The drone obstacle avoidance and buffer protection mechanism also includes a cover assembly 200, which is detachably connected to the buffer assembly 300.

[0033] The cover assembly 200 includes a cover body 210 and a cover handle 220. The cover handle 220 is integrally formed with the cover body 210, and the cover body 210 is detachably connected to the buffer layer periphery section 312; so as to realize the detachable connection between the cover assembly 200 and the buffer assembly 300.

[0034] It is worth mentioning that the specific composition and other technical features of the elastic material involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement methods of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0035] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
