Description
Technical field
The present invention relates to spacecraft general design, be specifically related to one and can open up front guiding mechanism.
Background technology
Along with the fast development of China's Aerospace Technology, the spacecraft structures such as satellite antenna, space station solar wing and survey of deep space solar sail are toward large scale development, and development large area front has become more and more urgent demand.On weight and volume, have huge advantage based on the large-area solar cell wing or large-size antennae etc. that can open up wavefront technology, be considered to the important development direction replacing traditional solar cell wing or antenna.In the vehicle launch stage, front is in folding storage state.After aircraft is entered the orbit, front launches gradually under the drive of framework.For guarantee front expansion process in order, expansion process not generating plane move outward, need to design some cover guiding mechanisms, front expansion process control effectively.Have the scheme utilizing rope to add spring to carry out leading abroad, but its spring type structures is complicated, in experimentation, guidance force not easily regulates.So design a nested structure simple, guidance force guiding mechanism easy to adjust becomes space can open up the important topic that wavefront technology development faces.
Summary of the invention
Moving outward to solve easy generating plane in current front expansion process, launching unstable, external existing program spring type structures is complicated, and in experimentation, guidance force such as not easily to regulate at the problem.
The present invention proposes one and can open up front guiding mechanism, this mechanism comprises: reel, supporting component, center shaft, plane scroll spring, coil spring box, guide rope, guide wheel assembly, it is characterized in that: described reel is a circular wheel disc, described reel and center shaft are fixed, and the side of front is fixed on by supporting component, described plane scroll spring the inner is fixing on center shaft, outer end and coil spring box are fixed, described coil spring box is fixed on the same side of front, described reel can rotate around supporting component, reel is fixed and is wound around guide rope, guide wheel assembly walked around by guide rope and front is arranged in parallel, guide rope is fixed with front opposite side through after some cable loop on front.
Further; in front expansion process; mechanism can discharge guide rope servo-actuatedly; the release of guide rope drives the rotation of reel; plane scroll spring is deformed; thus make guide rope keep tensioned state under the effect of plane scroll spring always, and by the cable loop on front, guidance force is delivered to front, make the protective effect being subject to guidance force in front expansion process.
Further, described plane scroll spring is rolled tightly in advance before front launches, savings part elastic resilience, in front expansion process, described plane scroll spring produces further elastic deformation, its elastic strain makes guide rope be in tensioned state by reel, thus is converted into the guidance force to front.
Further, connection between described reel and center shaft is adjustable, shaft hole matching place all along the circumferential direction more uniform knock holees of reel and center shaft, again mating between the position, hole passed through fixing screw of then screwing on can adjust setting angle between reel and center shaft easily.
Further, torque wrench can be inserted the spanner interface on center shaft, the moment of torsion of plane scroll spring can be regulated easily.
Further, regulate the prefastening torque of plane scroll spring with torque wrench while, the angle between reel and center shaft can be readjusted, to control the winding number of turns of guide rope on reel easily.
The invention has the beneficial effects as follows: of the present inventionly open up front guiding mechanism to have that volume is little, quality is light, structure is simple, guidance force is adjustable, reliability and stability advantages of higher, autonomy-oriented, the miniaturization that can open up front guiding mechanism can be realized.

Detailed description of the invention
Below in conjunction with accompanying drawing 1-3, the preferred embodiments of the present invention are described.
Fig. 1 is that the present invention can open up front guiding mechanism schematic diagram, this mechanism is by reel 1, supporting component 2, center shaft 3, plane scroll spring 4, coil spring box 5, guide rope 6, composition such as guide wheel assembly 7 grade, described reel 1 is fixed on center shaft 3 and exists, then the side of front is fixed on by supporting component 2, plane scroll spring 4 the inner is fixed on center shaft 3, outer end and coil spring box 5 are fixed, coil spring box 5 is also fixed on the same side of front, reel 1 can rotate around supporting component 2, reel 1 is fixed and is wound around guide rope 6, guide rope 6 is walked around guide wheel assembly 7 and is arranged in parallel with front, guide rope 6 is fixed with front opposite side through after some cable loop on front.Before guiding; there is predeformation in plane scroll spring 4; along with front launches; guide rope 6 is drawn out of; plane scroll spring 4 produces further distortion; guide rope 6 is tightened all the time, and by the cable loop on front, guidance force is delivered to front, make the protective effect being subject to guidance force in front expansion process.The invention solves and currently open up easy generating plane in front expansion process and move outward, launch unstable, external existing program spring type structures is complicated, in experimentation, guidance force such as not easily to regulate at the problem, has that volume is little, quality is light, structure is simple, guiding reliability and stability advantages of higher.
Fig. 2 is the guidance force adjustment schematic diagram that the present invention can open up front guiding mechanism, connection between described reel 1 and center shaft 3 is adjustable, shaft hole matching place all along the circumferential direction more uniform knock holees of reel 1 and center shaft 3, again mating between the position, hole passed through fixing screw of then screwing on can adjust setting angle between reel 1 and center shaft 3 easily.Torque wrench can be inserted the spanner interface on center shaft 3, the moment of torsion of plane scroll spring 4 can be regulated easily; While regulating plane scroll spring 4 prefastening torque with torque wrench, the angle between reel 1 and center shaft 3 can be readjusted, to control the winding number of turns of guide rope 6 on reel 1 easily.
Fig. 3 is the arrangement relation schematic diagram that the present invention can open up front guiding mechanism and front; in front expansion process; mechanism can discharge guide rope 6 servo-actuatedly; the release of guide rope 6 drives the rotation of reel 1; make plane scroll spring 4 that further distortion occur; thus keep guide rope 6 to be in tensioned state always, and by the cable loop on front, guidance force is delivered to front, make the protective effect being subject to guidance force in front expansion process.Described plane scroll spring 4 is rolled tightly in advance before front launches, savings part elastic resilience, in front expansion process, described plane scroll spring 4 produces further elastic deformation, its elastic strain makes guide rope 6 be in tensioned state by reel 1, thus is converted into the guidance force to front.
