Abstract

The invention discloses a manual and electric integrated driving device for a cabin door of a spacecraft. The driving device comprises a shell, a motor, a turbine, cabin penetrating shafts, a sliding rod, an elastic part, sliding gears, an output gear and a handle. The shell is arranged on the cabin door; the motor is arranged in the shell, and a worm is connected to an output shaft of the motor; the turbine is connected in the shell through a turbine bearing and is meshed with the worm; the cabin penetrating shafts are connected with the two sides of the shell in a penetrated manner through cabin penetrating shaft bearings; the sliding rod is movably connected in the two cabin penetrating shafts and can move on the axes of the cabin penetrating shafts in a back and forth manner; the elastic part is arranged between the cabin penetrating shafts and the sliding rod and is used for enabling the sliding rod to be kept at the middle position; the sliding gears are arranged on the sliding rod; the output gears are connected in the shell through an output gear bearing, are meshed with the cabin penetrating shafts and are used for transmitting and outputting power for opening or closing the cabin door; and the handle is matched with a key groove structure through a key structure, is detachably connected with the cabin penetrating shafts, and is used for driving the cabin penetrating shafts to rotate.

Description

technical field [0001] The invention relates to the field of cabin door driving structures, in particular to an integrated drive device for a spacecraft cabin door and a flashlight. Background technique [0002] At present, in the known driving mechanism of the cabin door of the aerospace vehicle, the technical solution of manual driving is mainly adopted, and it is laborious for the astronauts to manually operate in the case of weightlessness. In order to solve this problem, a technical solution using flashlight integrated drive was born, in which the manual and electric switching is realized by using an electromagnetic clutch. However, this structure has insufficient reliability in emergency situations, and the electric drive can only be used in the cabin, and the manual drive can only be used outside the cabin. Simultaneously, the device that this technical scheme adopts is complicated, and manual operation is laborious. Contents of the invention [0003] The pres...
