Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of unmanned aerial vehicles, more particularly, to an unmanned aerial vehicle protective cover. BACKGROUND

[0002] The unmanned aerial vehicle protective cover is a device for protecting unmanned aerial vehicles, mainly to prevent the rotors of the unmanned aerial vehicles from colliding with obstacles or contacting other objects during flight. The protective cover is usually made of light and impact-resistant materials such as plastic or metal to ensure effective protection without significantly increasing the flight weight. Its design can effectively reduce the damage risk of the unmanned aerial vehicle and prolong its service life, especially when operating in complex flight environments or narrow spaces, providing higher safety. At the same time, the protective cover can also prevent the fan blades from injuring surrounding personnel or objects, so it is very important in some high-risk or special task application scenarios. Through such a protective device, the unmanned aerial vehicle can better adapt to complex environments and improve flight stability and safety.

[0003] For the related technology in the above, the inventor believes that in the prior art, the traditional unmanned aerial vehicle protective cover generally adopts a buckle or bolt installation method, and the installation structure is mostly single and compact. Although this fixing method can ensure the stability of the protective cover, it cannot provide sufficient adjustable space, so the distance between the protective cover and the fan blades of the unmanned aerial vehicle cannot be effectively adjusted. When the unmanned aerial vehicle takes off, due to the fixed distance between the protective cover and the fan blades, the airflow of the blades of some unmanned aerial vehicles is disturbed, which affects the flight performance. Specifically, the airflow flows poorly or unevenly, causing thrust loss, reducing flight efficiency and stability. In addition, the disturbance of the blade airflow can also intensify the vibration of the unmanned aerial vehicle during flight, increasing the difficulty of control, and even in some cases, it may cause flight loss of control or damage. The deficiency of this installation method is particularly evident in high-load or complex environments, which brings potential hidden dangers and defects to the safety and performance of the unmanned aerial vehicle.
