Problems solved by technology

At present, the common form of pedals (built-in or external) adopts a stretcher structure. In order to ensure the stability and safety of the pedals during installation, it is necessary that the body structure on the left and right of the pedal installation can provide sufficient support strength and rigidity. This limits the installation position of the pedals, otherwise the support structure needs to be added locally, resulting in an increase in the weight of the structure

Abstract

The invention provides a helicopter rotary pedal, and relates to the field of design of helicopter engineering structures. The pedal comprises a rotating assembly and a pedal assembly, the rotating assembly comprises an upper joint (3), a lower joint (5) and a vertical shaft (4), the upper joint (3) and the lower joint (5) are connected with a machine body, and the vertical shaft (4) is rotationally arranged between the upper joint (3) and the lower joint (5); a limiting groove (51) is formed in the lower joint (5). The pedal assembly (1) is hinged to the vertical shaft (4), a limiting plate (13) is arranged on the pedal assembly (1), and one end of the limiting plate (13) can be contained in the limiting groove (51). The upper joint and a supporting joint are fixed to the structure of themachine body, the pedal assembly is unfolded and folded by rotating around a horizontal shaft and the vertical shaft, a force transmission route is optimized, and the reinforcing form of the machinebody structure is more simplified compared with that of a common pedal in the installation process; the rotary pedal can be hidden within the machine body when being folded, and space is saved compared with a common external pedal.

Description

technical field [0001] The invention relates to the field of helicopter engineering structure design, in particular to a helicopter rotary pedal. Background technique [0002] Pedals, as the key structure for maintaining the accessibility of the airframe, are widely used in helicopters. At present, the common form of pedals (built-in or external) adopts a stretcher structure. In order to ensure the stability and safety of the pedals during installation, it is necessary that the body structure on the left and right of the pedal installation can provide sufficient support strength and rigidity. This limits the installation position of the pedals, otherwise it is necessary to locally increase the support structure, resulting in an increase in the weight of the structure. Contents of the invention [0003] In order to solve the above problems, the present invention provides a helicopter rotary pedal, comprising: [0004] The rotating assembly includes an upper joint and a lo...
