Description
Technical field
What the present invention relates to is the butt joint and the releasing arrangement in a kind of space technology field, specifically is the awl-butt joint of bar type and the releasing mechanism of the little nano star station in a kind of space.
Background technology
The little nano star station in space is meant by several the small satellites of carrying out different task or same task as the component, organic being assembled on the female star, the microsatellite system that once launches by carrier rocket, and dock and take in the critical component of storage silo at the release that is the realization component in female star of the space-based butt joint of component and releasing mechanism and component and female star.Present international docking mechanism is general main adopt " awl-awl " type, allosome isomorphism type, " rod-cone " type, spring lock-handgrip type etc. are arranged, making with the most use at unmanned spacecraft intersection butt joint field still is back two kinds of patterns.
Find through literature search prior art, Ui Kyoichi etc. are at Proceedings of the AsianConference on Multibody Dynamics (Asia many-body dynamics conference proceedings), vol.2002, delivered " the Small Docking Mechanism for SmallMothership-Daughtership Satellites:on-ground experiments " ground experiment of satellites coupling mechanism (master and slave type receive) literary composition on the page.558-563, this article has proposed the docking mechanism that a kind of mechanical handgrip that is distributed by six groups of circumference array is formed, in the time of in the component enters efficient range, handgrip shrinks rapidly catching the component, and utilizes the roller on the handgrip to guide it to enter in the body of female star cabin.Its deficiency is that a cover docking mechanism can only corresponding component, has both increased the volume of female star, has increased the complexity of control system again.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art and defective, awl-the butt joint of bar type and the releasing mechanism of the little nano star station in a kind of space is provided, on the basis that absorbs tradition " rod-cone " type and primary and secondary star docking mechanism advantage mentioned above, initiatively follow the trail of mechanism and become " awl " (component) by " bar " (star station), that adopts that the acquisition mode of weak collision handgrip and bar creep goes into the cabin means, realize that little nano star station single pole disposes the requirement of finishing a plurality of docking missions, possesses simple in structure, performances such as cost is low, reliability height.
The present invention is achieved by the following technical solutions, the present invention includes three parts:
First is the target mechanism on little nano star station, comprising: receive bar, storage cabin and limit baffle ring, the reception bar runs through the axis of storage cabin and extends to out of my cabin, and limit baffle ring is positioned at the bottom centre of storage cabin.
Second portion is the tracking mechanism on the component, comprise: butt joint awl, butt hole, handgrip formula driving roller, return idler and spacing bumpar post, the butt joint awl is on the top of component, butt hole links to each other with the top of butt joint awl, runs through the component axis, and handgrip formula driving roller is distributed on the inwall on butt hole top, return idler is arranged on the butt hole inwall behind the handgrip formula driving roller, respectively have four groups, be circle distribution, spacing bumpar post is positioned at the component afterbody.
Third part is a catch gear, comprising: locking anchor and ring-type teeth groove, both lay respectively on the inwall of storage cabin on the outer wall with the component.
The present invention utilizes " awl-bar " contact principle to finish docking operation: the reception bar that stretch out near little nano star station with certain initial velocity the component, the butt joint awl, contact force after the collision of reception bar is ordered about the reception bar and is entered in the butt hole of component, handgrip formula driving roller shrinks immediately, compress and receive bar and rotation, driving the component creeps along bar, final assisting down at return idler, the component axially enters in the storage cabin along receiving bar, handgrip formula driving roller stops operating after running into limit baffle ring in the cabin, the locking anchor puts down rapidly, embed in the ring-type teeth groove of component outer wall, finish locking action.The docking operation all fours of next component, the spacing bumpar post of only going up a component afterbody has replaced the effect of limit baffle ring.The similar stack architecture of the storage mode of component is followed the principle of going into earlier afterwards to go out.The release of component is entirely inverse process: the component release, and the counter-rotating of handgrip formula driving roller, the component is along receiving the bar axial separation.
Compared with prior art, the present invention has realized that single reception bar finishes the requirement of a plurality of docking missions, has simplified the complexity of docking mechanism greatly; The driving mechanism of the overwhelming majority all is arranged on the component, thereby has improved the reliability of little nano star station; Receiving bar is joint unit, is again the support that stop the component, and actv. has increased the space availability ratio at star station; Adopt the weak collision docking mode, do not have complicated ACTIVE CONTROL system, cost is relatively low.
