The invention discloses an aircraft folding type propeller mechanism and an aircraft, the aircraft folding type propeller mechanism comprises a rotating shaft, a driving part, a first propeller and a second propeller; the driving piece is connected with one end of the rotating shaft; the first propeller comprises a first propeller hub and a first propeller blade which are connected with each other, the first propeller hub is fixedly connected to the rotating shaft, a thrust groove is formed in the side, away from the driving part, of the first propeller hub, and a first thrust surface which is obliquely arranged is arranged at the bottom of the thrust groove; the second propeller comprises a second propeller hub and a second propeller blade which are connected, the second propeller hub is movably arranged on the rotating shaft in a sleeving mode and located on the side, away from the driving piece, of the first propeller hub, and a thrust block extending into the thrust groove is arranged on the side, facing the first propeller hub, of the second propeller hub in a protruding mode; and the thrust blocks are matched with the thrust grooves, so that the second paddles are in a folded state or an unfolded state relative to the first paddles. According to the folding propeller mechanism of the aircraft, the resistance of the aircraft in the flight process is reduced, and the flight performance of the aircraft is improved.

    本申请公开了一种飞行器折叠式螺旋桨机构及飞行器,飞行器折叠式螺旋桨机构,包括转轴、驱动件、第一螺旋桨及第二螺旋桨;驱动件与转轴的一端连接;第一螺旋桨包括相连接的第一桨毂和第一桨叶,第一桨毂固定连接于转轴,第一桨毂背离驱动件的一侧开设有推力槽,推力槽的槽底具有倾斜设置的第一推力面;第二螺旋桨包括相连接的第二桨毂和第二桨叶,第二桨毂活动套设于转轴并位于第一桨毂背离驱动件的一侧,第二桨毂朝向第一桨毂的一侧凸设有伸入推力槽的推力块,推力块和推力槽相配合使第二桨叶呈现为相对于第一桨叶的折叠状态或展开状态。上述飞行器折叠式螺旋桨机构降低了飞行器在飞行过程中的阻力,提高了飞行器的飞行性能。
