Air suspended sun umbrella

Abstract

The invention provides an air suspended sun umbrella which is based on a multi-rotor craft and can keep an umbrella body to shield sunlight all the time and fly while automatically tracking movement of a pedestrian. The air suspended sun umbrella comprises a body, umbrella fabric, rotor devices, free turning devices, locking devices, an illumination detecting device, a shielding detecting device, a control device and a power supply device, wherein a stretchable body structure is used for spreading the elastic umbrella cloth; the rotor devices are used for realizing relative rotation with the body by the aid of the free turning devices; the locking devices are used for locking or removing free turning of the free turning devices; the illumination detecting device is used for detecting the illumination angle of the umbrella cloth; the shielding detecting device is used for detecting the position and the deviation of the umbrella shielding area; the control device is used for composite control of the rotating speed of each rotor to change the sun-shading attitude of the sun umbrella in the air and realize tracking flight for the pedestrian with the maximum sun-shading attitude; besides, the power supply device can efficiently acquire sunlight for solar power storage by the aid of the flight attitude. The invention belongs to the field of multi-rotor crafts.

Description

Technical field [0001] The invention relates to a multi-rotor aircraft, in particular to an air-suspended sun umbrella based on the multi-rotor aircraft and having a sunshade function. Background technique [0002] At present, most of the sun umbrellas are held or worn on the head for sunshade, and there is no sun umbrella that does not rely on people's limb support, but floats in the air and automatically follows people's walking and flies. With the development and popularization of multi-rotor aircraft technology, the sun umbrella that utilizes multi-rotor aircraft to realize hovering and tracking functions in the air is an interesting development content for future scientific and technological life. However, because the rotor device and the fuselage of the existing multi-rotor aircraft are integrated, it is difficult to hover in the air to effectively block the setting sun, and it is also unable to maintain an effective sun-shading posture in the air to automatically trac...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to combine the multi-rotor aircraft with the sun umbrella. By solving the free transformation of the attitude of the sun umbrella in the air and the flight problem of maintaining a specific attitude, the sun umbrella can always face the sun in the air, and thus Attitude realizes automatic tracking of pedestrians and flight shading
