Problems solved by technology

This application attempts to standardize and compact the folding method of the canopy, but the folding method still requires multiple steps, and the folding structure is still relatively complicated, which is not conducive to mass production, the compactness of the folding structure, and the improvement of the umbrella opening process determined by the folding structure. Ride comfort and reliability can still be further improved

Abstract

The invention discloses a parachute folding structure, a folding mold and a parachute module for unmanned aerial vehicle express box putting, and an unmanned aerial vehicle system for express box putting using the parachute module and a parachute opening method. The folding structure is folded back and forth from the center of the parachute along an upper folding line and a lower folding line in the outward radiation direction to form a concentric corrugated shape; the folding structure is formed by pressing through a mold; the parachute module comprises a bottom box, a middle ring and a folded parachute, and the middle ring is fixed to the center part and detachably connected to the lower portion of the unmanned aerial vehicle air-drop device through a parachute opening connecting piece. And the connection force between the parachute opening connecting piece and the air-drop device is enough to keep connection before the air-drop operation of the unmanned aerial vehicle and in the parachute opening process of the air-drop operation, and meanwhile, the unmanned aerial vehicle express box can be separated from the unmanned aerial vehicle and the parachute can be separated under the action of vertical pulling force after the parachute is completely pulled out. The parachute folding structure is simple and compact in structure, small in size after being folded, suitable for standardized and large-scale low-cost production, and smooth and reliable in parachute opening.

Description

technical field [0001] This application relates to the field of parachute technology for delivery of UAV express boxes and the field of UAV technology, and in particular to a parachute module for delivery of UAV delivery boxes and its parachute folding structure, folding mold, parachute opening method, and an express delivery method. Box delivery with an unmanned aerial system. Background technique [0002] The delivery method of the existing UAV express box is mainly to drop the UAV directly on the ground, or to drop it by rope when the UAV is in the air. However, for the sake of safety, in some complex environments, drones cannot approach and land in the delivery area, so it is impossible to use the hanging rope method or land on the ground to complete the delivery of express boxes. In this case, it is a better choice to use a parachute to drop the express box. [0003] However, at present, express boxes and umbrellas are still rarely used. Except that some items in the ...
