Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicles, and specifically relates to an unmanned aerial vehicle with a quickly deployable, throwable, foldable and inflatable life-saving mechanism. Background Art

[0002] An unmanned aerial vehicle (UAV) is short for an unpiloted aerial vehicle and is also regarded as an "aerial robot". It can complete aerial tasks in various fields by carrying different payloads. A UAV is an aircraft managed by a control station (including remote operation or autonomous flight). It does not require personnel to board and can fly autonomously or by remote control. According to its uses, UAVs are mainly divided into military UAVs and civilian UAVs. Military UAVs are mainly used for military tasks such as reconnaissance, surveillance, and target acquisition. Civilian UAVs are widely used in multiple fields such as agriculture, film production, logistics, disaster relief, inspection, surveying and mapping, construction, public safety, as well as scientific research and education. As a high-tech product, UAVs play an important role in multiple fields. With the continuous progress of technology and the continuous expansion of application fields, the future development prospects of UAVs will be even broader.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) During work, the operator controls the UAV body to fly to the dropping location. Then, the operator starts the driving motor to drive the rotating shaft to rotate inside the bearing. When the rotating shaft rotates, it drives the driven bevel gear to rotate through the driving bevel gear. When the driven bevel gear rotates, it drives the rotating rod to rotate inside the four rotating sleeves. When the rotating rod rotates, it drives the two transmission pins to rotate inside the two moving strips through the two transmission strips, thereby driving the two moving strips to move downward. When the two moving strips move downward, they drive the moving platform to move downward through the four support rods. When the four support rods move downward, they drive the four limit blocks to slide inside the four limit slots, increasing the stability of the moving platform during movement. When the moving platform moves downward, it drives the folding inflatable pad to move downward outside the placement box;

When the two transmission gears rotate, they drive the driving sprocket to rotate. When the driving sprocket rotates, it drives the driven sprocket to rotate through the chain. When the driven sprocket rotates, it drives the shaft rod to rotate inside the shaft sleeve. When the shaft rod rotates, it drives the two threaded sleeves to move away from each other through the two threaded rods. When the two threaded sleeves move away from each other, they drive the two sliders to slide inside the two chutes, increasing the stability of the two threaded sleeves during movement. When the two threaded sleeves move away from each other, they drive the support plate to move downward through the two adjusting rods, thereby unfolding the folding inflatable pad;

[0017] (3) Immediately afterwards, the operator starts the electric telescopic rod to push the pushing strip, so that the pushing strip pushes the folding inflatable pad to fall, thereby realizing the dropping; enabling this UAV to have the ability to quickly deploy and throw water rescue tools, so as to be able to support the trapped people on the water in a timely manner, with very good use effects.
