Embodiment Construction

[0026] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The main solution of the embodiment of the present invention is: through the electrical connection terminal group, the two connecting seats are fixedly butted, and at least one of the two connecting seats is connected to the connected paddle arm segment in a non-fixed position (non-fixed position connection refers to a movable connection) , but its range of motion is limited within a certain range, which means that it can offset the slight swing of the section of the paddle arm where the blade is installed), so that one of the connecting seats has a In the case of a slight swing, it can swing with the other connecting seat of the slight movement, reducing or avoiding the deformation of the electrical connection terminal group, thereby avoiding the problem of poor contact in the subsequent connection process, and...

Abstract

The invention discloses a propeller arm connection assembly. Propeller arms are installed on a machine body of an aircraft. Each propeller arm comprises a propeller arm first segment and a propeller arm second segment. The propeller arm connection assembly comprises a first connecting base and a second connecting base fixedly connected with the first connecting base in a butting mode through electric connectors. The first connecting base is connected with the propeller arm first segments, and the second connecting base is connected with the propeller arm second segments. At least one of the first connecting base and the second connecting base is in non-fixed limiting connection with the corresponding propeller arm first segment or the corresponding propeller arm second segment. According to the propeller arm connection assembly, one connecting base can swing together with the other connecting base which joggles under the condition that the propeller arm segments provided with paddles joggle; deformation of the electric connectors is reduced or avoided; and therefore poor contact in the subsequent connection process is avoided, and stability and safety of the aircraft are greatly improved.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a paddle arm connection assembly and an aircraft. Background technique [0002] At present, in order to facilitate the packaging and transportation of the aircraft, a solution adopted is to make the paddle arms of the aircraft detachable or foldable. However, after the aircraft is assembled, the section of the paddle arm where the blade is installed has a slight swing, and the electrical connection terminals in the paddle arm will be deformed under the action of this swing, resulting in poor contact in the subsequent connection process. Contents of the invention [0003] The main purpose of the present invention is to provide a paddle arm connection assembly and an aircraft, aiming to solve the problem of poor contact in the subsequent connection process caused by the deformation of the electrical connection terminals in the detachable or foldable paddle arm due to the swingin...
