Abstract

The invention discloses a multi-motor driven Y-shaped rod unilateral unfolding mechanism. A Y-shaped rod is a super-elastic rod made of a carbon fiber composite material, has a Y-shaped cross sectionand can be pressed flat, bent and wound, and automatic unfolding can be achieved through elastic potential energy stored through bending deformation; a Y-shaped rod unilateral driving mechanism is mainly composed of a roller transmission mechanism, a rocker arm transmission mechanism, a root fixing support mechanism and a supporting frame. The roller transmission mechanism is mainly used for storing and stretching the Y-shaped rod after pressing flat and winding, the rocker arm transmission mechanism is mainly used for flattening and bulging a root part of the Y-shaped rod, the root fixing support mechanism is mainly used for fixing the root part of the Y-shaped rod to enhance the rigidity of the Y-shaped rod in an unfolded state, and the supporting frame is mainly used for maintaining relative positions of various parts of a Y-shaped rod system and the stability of the entire mechanism. According to the multi-motor driven Y-shaped rod unilateral unfolding mechanism, the folding and unfolding ratio is large, the size is small, the weight is light, the unfolding speed is adjustable, the supporting frame enhances the rigidity of the Y-shaped rod during unfolding, and normal unfoldingof the Y-shaped rod is ensured.

Description

technical field [0001] The invention belongs to the technical field of aerospace mechanisms, and in particular relates to a multi-motor-driven one-side deployment mechanism of a humanoid rod. Background technique [0002] At the beginning of the launch of the spacecraft, the humanoid rod is tightly wound and stored in the load cabin. After the orbit is released, the elastic strain energy stored in the winding and bending process of the humanoid rod is used to drive the film under the drive of the motor (this mechanism can also be used for Drive the solar sail, the solar sail and the film antenna belong to the film structure, so it is more appropriate to use the film structure.) The structure is unfolded, and the motor is used to control the unfolding speed of the human-shaped rod, which reduces the impact of the impact of the end of the human-shaped rod on the entire film structure, and finally completes The on-orbit deployment of the humanoid rod and the space deployment me...
