Problems solved by technology

The existing docking mechanism is mainly designed for the rendezvous and docking of large spacecraft with large volume and mass, such as the rendezvous between a spacecraft and a space station. The structure is complex and the cost is high, but there are few docking mechanisms designed for small spacecraft

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0014] The basic technical proposal of the present invention is: the cam-claw type novel space docking mechanism mainly includes a claw mechanism and a driving mechanism. The claw mechanism consists of two circular docking plates and three claws. The two circular docking plates are installed on the tracking spacecraft and the target spacecraft respectively. The three claws are evenly hinged on the docking plate at 120 degrees, and only One rotational degree of freedom. When docking, the drive mechanism consists of a drive motor and a space cam. The driving motor drives the space cam fixed on it to rotate, and the claws rotate under the action of the curved surface of the cam until hooking the docking port on the target docking disk. At this moment, the motor stops rotatin...

Abstract

The invention provides a cam-hook claw type space docking mechanism. Two docking disks are fixedly connected with a tracking spacecraft and a target spacecraft, which are respectively known as an active docking disk and a target docking disk; at least one hook claw is hinged to the active docking disk and has only one rotational degree of freedom; an end surface of a space cam perpendicular to an axis is a curved surface; a driving motor drives the space cam to rotate about the axis; the curved surface of the space cam pushes the hook claw to rotate about a hinge shaft until the hook claw hooks the target docking disk, or to rotate from a state of hooking the target docking disk to a state of releasing the target docking disk. The cam-hook claw type space docking mechanism provided by the invention is compact in structure, light in weight, high in reliability, and capable of being used repeatedly.

Description

technical field [0001] The invention relates to a space docking mechanism, which belongs to the field of spacecraft space on-orbit service. Background technique [0002] The rendezvous and docking process is often involved in the space operations of spacecraft such as space shuttles, space stations, spacecraft, and satellites, and this process relies on effective and reliable space docking mechanisms. At present, there are roughly four types of docking devices in the world: ring-cone type, rod-cone type, heterogeneous isomorphic peripheral type, and gripper collision lock type. The existing docking mechanisms are mainly designed for the rendezvous and docking of large spacecraft with large volume and mass, such as the rendezvous between a spacecraft and a space station. The structure is complex and the cost is high, while there are few docking mechanisms designed for small spacecraft. Contents of the invention [0003] In order to overcome the deficiencies in the prior ar...
