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.

    本申请公开了一种无人机快递盒投放用降落伞折叠结构、折叠模具和降落伞模块,以及使用所述降落伞模块的快递盒投放用无人机系统和开伞方法。所述折叠结构从降落伞的中心起,在向外辐射的方向上沿上下折叠线来回折叠形成同心皱褶形状;该折叠结构通过模具压制而成;所述降落伞模块包括底盒、中圈和折叠好的降落伞,中圈固定至中心部分、通过开伞连接片可脱开地连接至无人机空投器下方,开伞连接片与空投器之间的连接力足以在无人机进行空投操作前以及空投操作的开伞过程中保持连接、同时在无人机快递盒脱离无人机且降落伞被完全拉出后在上下拉力的作用下能脱开。本申请结构简单紧凑、折叠后体积小、适合标准化和大规模低成本生产、开伞平顺可靠。
