Less than the radian of the first tape spring 8.First cementing place, the third seal 11 and for drawing money on credit stay tube 10 and the second tape spring 12
The cementing place of two tape springs 12, the cementing place of the 4th seal 13 and the second tape spring 12 and second are drawn money on credit stay tube 14 and
The section radian at the cementing place of two tape springs 12 is not less than the radian of the second tape spring 12.Second draws money on credit stay tube 14 and
The cementing places of three tape springs 16, the cementing place of the 5th seal 15 and third tape spring 16, the 6th seal 17 and third are band-like
The cementing place of spring 16 and the second short support tube and the section radian at the cementing place of third tape spring 16 are not less than third
The radian of tape spring 16.First short support tube 6, the first seal 7, the second seal 9, first draw money on credit stay tube 10, third seal 11,
4th seal 13, second draw money on credit stay tube 14, the 5th seal 15, the 6th seal 17 and the second short support tube global sections shape it is equal
Match with the radian of tape spring, i.e., section is not less than the arc of tape spring with the radian at the cementing contact surface of tape spring
Degree.
It is above-mentioned it is all (the first tape spring 8, the second tape spring 12 are identical with the structure of third tape spring 16, first
Short support tube 6, the first seal 7, the second seal 9, first are drawn money on credit stay tube 10, third seal 11, the 4th seal 13, the second long support
Pipe 14, the 5th seal 15, the 6th seal 17 and the second short support tube) cross sectional shape be:The ellipse closing that N sections of circular arcs are constituted
Figure, N is the positive integer more than or equal to 4, to ensure the performance of tape spring.Preferably section is oval or 4 sections of circular arc structures
At ellipse closed figure, can more preferably play the expanding performance of tape spring.It is illustrated in figure 3 the ellipse of 4 sections of circular arcs composition
Type closed figure is joined end to end and is constituted by first segment arc 19, second segment arc 20, third section arc 21 and the 4th section of arc 22, wherein the
One section of arc 19 and the circular arc that third section arc 21 is same shape, radian are not less than the radian of tape spring, and width is not less than
The width of tape spring, that is, 21 cementing tape spring of first segment arc 19 and third section arc.Second segment arc 20 and the 4th section
Arc 22 is the circular arc of same shape.Ellipse closed figure is structure as a whole.
First tape spring 8, the second tape spring 12 are identical with the structure of third tape spring 16, the first short support tube 6
It is identical with the structure and material of the second short support tube, first draw money on credit stay tube 10 and second draw money on credit stay tube 14 structure and material phase
Together.First short support tube 6, the second short support tube, first draw money on credit stay tube 10 and the second stay tube 14 of drawing money on credit is all made of thin-wall construction,
Thickness is 0.4~1.5mm, greatly reduces the weight of supporting mechanism 4, it is Wrapping formed to be all made of carbon fibre composite.It is all
Seal is of similar shape, structure and material, and it is Wrapping formed to be all made of carbon fibre composite.
Supporting mechanism 4 needs folded strip spring, three tape springs of hand foldable, the then gathering of supporting mechanism 4 when collapsing;
Or the second tape spring of hand foldable 12, the first tape spring 8 and third band-like bullet when the second tape spring 12 folds
The auto-folder therewith of spring 16, then supporting mechanism 4 collapse.Rounding state as shown in figure 4, when rounding state, deposit by tape spring hinge
Store up elastic strain energy, can spontaneous rebound be expanded to original state.After supporting mechanism 4 collapses, the hold-down mechanism of itself of solar wing 3 makes
Solar wing 3 is pressed on satellite health 1, and supporting mechanism 4 is made to keep rounding state.Opening solar wing 3 hold-down mechanism of itself,
Then solar wing 3 is realized under the common driving of unfolding mechanism 2 and supporting mechanism 4 and is unfolded and locks.In unfolding mechanism 2 without driving force
When, supporting mechanism 4 can also rely on tape spring natural resiliency strain energy and automatically open.
Supporting mechanism 4 can with 2 groups or it is multigroup use simultaneously, i.e., it is used in parallel, can more effectively improve 3 fundamental frequency of solar wing,
And be not in not coaxial stuck situation between supporting mechanism 4.Fig. 5 is that expansion when two of supporting mechanism 4 are used in parallel is shown
It is intended to.
The present invention 4 constitutional detail quantity of supporting mechanism is few, simple in structure, integral molding.Supporting mechanism 4 can bootstrap
It opens, gathering is easy to operate, passes through solar wing 3 and satellite health 1 keeps collapsing.Multiple supporting mechanisms 4 can be used simultaneously and be not easy
Not coaxial stuck phenomenon occurs, reliability is high, and the present invention improves the expansion rigidity of solar wing 3, improves optical satellite solar wing 3
The fundamental frequency of expansion.
