Description
Technical field
The present invention relates to a kind of deployable structure combined by scissors unit and rectangular aluminum sheet, and realize the folding of structure by arranging of pin-connected joints and launch.
Background technology
Deployable structure is a kind of new structure closely grown up for more than half a century, plays an important role in fields such as aerospace, building structure and military engineerings.The principal character of deployable structure has two kinds of stable configurations: folded state and state of organizing work completely completely.When folded state, structure is drawn at a certain given shape, and under the effect of extraneous driving force, structure is progressively launched, and reaches the duty launched completely, is then locked as stable state.
Can open up scissors hinge structure is a kind of space structures based on scissors hinge unit, can design colourful geometric shape.Become after this structure is completely folding and tie shape closely, fully expansion reaches original operating state after fixing, and can cover larger space.Total can be produced by batch in factory simultaneously, and after completing, folding bundled shape is transported to building site and launches use; In addition, this class formation is extremely convenient to remove.Utilize this feature, this structure can be widely used in military architecture, short-term building, and in the large-span space structure such as stadium grand theater.
In existing structure, scissors are cut with scissors structure and are mostly to exist as vertical lifting device, and utilize scissors to cut with scissors structure and open front and after opening in shape and height huge difference, it has and well promotes effect.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, and provide a kind of portable, have larger folding ratio, based on the circular development support of scissors unit.
Technical scheme: for achieving the above object, the technical solution used in the present invention is:
A kind of circular development supporting structure, it is characterized in that: comprise top scissors unit circle, bottom scissors unit circle and junction plate, described top scissors unit circle is formed by the first X-type connecting rod head and the tail mutual series connection pin joint, first X-type connecting rod is formed by two the first connecting plate pin joints, and the pin joint point of two the first connecting plates is the first pin joint point, described bottom scissors unit circle is formed by the second X-type connecting rod head and the tail mutual series connection pin joint, second X-type connecting rod is formed by two the second connecting plate pin joints, the pin joint point of two the second connecting plates is the second pin joint point, the first described pin joint point and the second pin joint point are positioned on two different concentric circles of radius, the first described X-type connecting rod, second X-type connecting rod and junction plate number identical, described junction plate to be arranged between described top scissors unit circle and bottom scissors unit circle and to be positioned in described concentrically ringed radial direction, the upper end of junction plate and top scissors unit circle are at the first pin joint point pin joint, the lower end of junction plate and bottom scissors unit circle are at the second pin joint point pin joint.
The outer end of described top scissors unit circle and the outer end of bottom scissors unit circle are on the circle of same Radius, and the length of described first X-type connecting rod is greater than the length of the second X-type connecting rod.
Described junction plate is 48 pieces.
Supporting structure of the present invention is formed by pin pin joint by scissors unit and junction plate, and wherein junction plate is rectangular aluminum sheet; Described scissors unit comprises two circles, and bottom scissors unit is formed by pin pin joint by two blocks of bar shaped aluminium sheets, between the scissors unit of bottom respectively in end by pin pin joint together, and the scissors unit circle that after launching, formation one is annular; Same, top scissors unit circle is formed by top scissors unit and pin pin joint; Wherein, at the contact surface of pin and scissors unit, on the contact surface between scissors unit, all there is tetrafluoro backing plate; The lower end of described one piece of rectangular aluminum sheet and top scissors unit in the position of its two pieces of bar shaped aluminium sheet pin-connects together with scissors unit pin joint, the upper end of described rectangular aluminum sheet respectively with top scissors unit in the position of its two pieces of bar shaped aluminium sheet pin-connects together with scissors unit pin joint.And a pin joint point of every block rectangular aluminum sheet lower end and a pin joint point of upper end be not on same vertical curve.
Preferably, whole braced structures adopts 48 pieces of rectangular aluminum sheet, and after supporting structure launches, the angle between every two pieces of rectangular aluminum sheet is 7.5 °, and the elongated central line of all rectangular aluminum sheet points to the same center of circle.One piece of rectangular aluminum sheet is fixed every 90 °.
Beneficial effect: supporting structure of the present invention, the junction plate between upper and lower two circle scissors cell pairs is adopted to carry out launching and folding, and pin joint point junction plate and upper and lower two being enclosed scissors unit is arranged on the different concentric circles of radius, not only simply can improve the folding ratio of junction plate, and when being deployed in any position, the position of junction plate is all fixing sensing home position.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown be a kind of circular development supporting structure schematic diagram based on inventive concept, formed by pin 4 pin joint by scissors unit and junction plate 3, wherein scissors unit comprises bottom scissors unit circle 1 and top scissors unit circle 2, and junction plate 3 selects rectangular aluminum sheet.
Bottom scissors unit circle 1 comprises the first X-type connecting rod 11 of two pieces of bar shaped connecting plates by pin 4 pin joint, between adjacent two the first X-type connecting rods 11 respectively in end by pin 4 pin joint together, and the scissors unit circle that after launching, formation one is annular; Same, top scissors unit circle 2 is formed with pin 4 pin joint by the second X-type connecting rod 21 respectively; Wherein, at the contact surface of pin 4 with scissors unit, on the contact surface between scissors unit, all there is tetrafluoro backing plate.The lower end of one piece of rectangular aluminum sheet and bottom scissors unit 1 in the position of its two pieces of bar shaped aluminium sheet pin-connects together with scissors unit pin joint, the upper end of rectangular aluminum sheet respectively with top scissors unit circle 2 in the position of its two pieces of bar shaped aluminium sheet pin-connects together with scissors unit pin joint, as shown in Figure 6.And two pin joint points of every block rectangular aluminum sheet upper end and a pin joint point of lower end be not on same vertical curve.Whole supporting structure adopts 48 pieces of rectangular aluminum sheet, and the angle between every two pieces of rectangular aluminum sheet is 7.5 °, and the elongated central line of rectangular aluminum sheet points to the same center of circle.One piece of rectangular aluminum sheet is fixed, as shown in Figure 1 every 90 °.
Implementation procedure: the position after first utilizing computer to draft rectangular aluminum sheet expansion, arranges scissors unit at assigned address afterwards, is coupled together by each scissors unit, just define folding ring support.
