Description
Technical field
The invention belongs to space technology field, be specifically related to a kind of front end and expand formula inflation docking mechanism.
Background technology
Space tasks comprises the extraterrestrial targets such as satellite are docked in-orbit, to realize the operations such as the capture of extraterrestrial target, posture adjustment, change rail and transfer, existing docking mechanism uses mechanical type docking mechanism, there is the shortcomings such as structure is complicated, transmitting size is big, it is high to control requirement, control difficulty is big, easy damaged docking target, therefore, need a kind of Space Docking Mechanism novel, that be easily manipulated, to reduce docking difficulty and the cost of extraterrestrial target.
Summary of the invention
The invention aims to solve existing docking mechanism and use mechanical type docking mechanism, there is the problem that structure is complicated, it is big to launch size, control the shortcomings such as requirement is high, it is big to control difficulty, easy damaged docking target, providing a kind of front end and expand formula inflation docking mechanism, its technical scheme is as follows:
Formula inflation docking mechanism is expanded in a kind of front end, it comprises a stay tube and expands termination, expand termination and be arranged on the front end of a stay tube, expand termination to align setting with support tube hub, expansion termination is fixing with a stay tube to be connected, prop up stay tube and expansion termination is all flexible gas-filled structure, expanding termination is spherical, cylindricality, the arbitrary shape such as square, the external diameter propping up stay tube is less than the length of the longest straight line distance expanded on the cross section that termination is parallel with the cross section of a stay tube, it is spherical for such as expanding termination, and the external diameter of a stay tube is less than the diameter expanding termination；Such as expanding termination is cylindricality, and when expanding that termination is identical with the axial direction of stay tube to be arranged, the external diameter of a stay tube, less than expanding the external diameter of termination, expands the axial direction of termination and a stay tube when being vertically arranged, and the external diameter of a stay tube is less than the length of expansion termination；It is foursquare for such as expanding termination, and the external diameter of a stay tube is less than the catercorner length on the surface expanding termination, etc.；The side of a stay tube is provided with longitudinal wind spring, can fold with wind spring automatic curled after a stay tube and the venting of expansion termination；Being respectively arranged with trachea on a stay tube and expansion termination, the trachea on a stay tube is arranged on the rear end of a stay tube, and the trachea expanding termination is arranged on inside a stay tube；Propping up stay tube and expansion termination all uses flexible composite, expand termination and comprise inner liner, bearing layer and elastic layer, a stay tube comprises inner liner and bearing layer, and inner liner material is butyl rubber thin-film material, the stability of holding structure the blowing pressure；Bearing layer is aramid fiber reinforced composite, undertakes the blowing pressure in structure；Elastic layer material is rubber film material, is used for the expansion termination after shrinking venting.
The invention have the benefit that front end expand formula inflation docking mechanism have simple in construction, be prone to docking, docking operation controls to require that low, control mode is simple, little, lightweight, low cost and other advantages of launching volume, and expansion termination, front end is flexible gas-filled utricule structure, it is suitable for different docking port Inner structural shapes and size, target strong adaptability, and docking target will not be caused damage；It is widely portable to docking port and there is the opening size docking less than the objective body of interior space dimension.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention:
With reference to Fig. 1, formula inflation docking mechanism is expanded in a kind of front end, it comprises a stay tube 1 and expands termination 2, expand termination 2 and be arranged on the front end of a stay tube 1, expand termination 2 to arrange with stay tube 1 center alignment, expansion termination 2 is fixing with a stay tube 1 to be connected, prop up stay tube 1 and expansion termination 2 is all flexible gas-filled structure, expanding termination 2 is spherical, cylindricality, square arbitrary shape such as grade, the external diameter propping up stay tube 1 is less than the length of the longest straight line distance expanded on the cross section that termination 2 is parallel with the cross section of a stay tube 1, it is spherical for such as expanding termination 2, prop up the external diameter of stay tube 1 less than the diameter expanding termination 2；Such as expanding termination 2 is cylindricality, expand termination 2 with prop up stay tube 1 axial direction identical arrange time, propping up the external diameter external diameter less than expansion termination 2 of stay tube 1, when expansion termination 2 is vertically arranged with the axial direction propping up stay tube 1, the external diameter of a stay tube 1 is less than the length of expansion termination 2；It is foursquare for such as expanding termination 2, and the external diameter of a stay tube 1 is less than the catercorner length on the surface expanding termination 2, etc.；The side of a stay tube 1 is provided with longitudinal wind spring 3, can fold with wind spring 3 automatic curled after a stay tube 1 and the venting of expansion termination 2；Being respectively arranged with trachea on a stay tube 1 and expansion termination 2, the trachea on a stay tube 1 is arranged on the rear end of a stay tube 1, and the trachea expanding termination 2 is arranged on stay tube 1 inside；Propping up stay tube 1 and expansion termination 2 all uses flexible composite, expand termination 2 and comprise inner liner, bearing layer and elastic layer, a stay tube 1 comprises inner liner and bearing layer, and inner liner material is butyl rubber thin-film material, the stability of holding structure the blowing pressure；Bearing layer is aramid fiber reinforced composite, undertakes the blowing pressure in structure；Elastic layer material is rubber film material, is used for the expansion termination 2 after shrinking venting.
Preferably, 1/2nd of the length of the longest straight line distance on cross section that to prop up the external diameter of stay tube 1 parallel with the cross section propping up stay tube 1 less than expanding termination 2.
Docking port on objective body and the diameter diameter slightly larger than a stay tube 1 propping up stay tube 1 corresponding position, make a stay tube 1 easily insert in docking port.
Operation principle: before inflation, expands termination 2 and shrinks under the effect of elastic layer, and a stay tube 1 is folded in the effect last volume complications of wind spring 3, and overall volume reduces, convenient delivery；First a stay tube 1 is made to launch stay tube 1 inflation during docking, again stay tube 1 front end is inserted in the docking port of objective body, then expansion termination 2 is inflated, under the blowing pressure effect, expand termination 2 and a stay tube 1 all has certain rigidity and hardness, objective body firmly can be connected, can carry out objective body after connection becoming the operation such as rail, Powered Propulsion；When separating with objective body, first exit to expanding termination 2, expand termination 2 and enter to shrink in the effect of elastic layer, then stay tube 1 remove in docking port, finally a stay tube 1 is exitted, folded in the effect last volume complications of wind spring 3 after stay tube 1 venting.
