Abstract
The invention discloses an annular-unfolding support structure. The support structure comprises a top shear type unit ring, a bottom shear type unit ring and connecting plates. The top shear type unit ring comprises first X-shaped connecting rods which are serially connected end to end and in pin connection. Each first X-shaped connecting rod comprises two first connecting plates in pin connection, and the pin connection point of the two first connecting plates is a first pin connection point. The bottom shear type unit ring comprises second X-shaped connecting rods which are serially connected end to end and in pin connection. Each second X-shaped connecting rod comprises two second connecting plates in pin connection, and the pin connection point of the two second connecting plates is a second pin connection point. The first pin connection points and the second pin connection points are located on two concentric circles of different radiuses. The upper end of each connecting plate is in pin connection with the top shear type unit ring at one first pin connection point. The lower end of each connecting plate is in pin connection with the bottom shear type unit ring at one second pin connection point. Due to the fact that the pin points of the top shear type unit ring and the bottom shear type unit ring of the support structure are not on the same straight line, a bar-type aluminum plate can be fixed.

Technical field
The present invention relates to a kind of deployable structure being combined by scissors unit and rectangular aluminum sheet, and arranging the folding of implementation structure and launching by pin-connected joints.
Background technology
Deployable structure is a kind of new structure closely growing 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 is to have two kinds of stable configurations: folded state and the state of organizing work completely completely.In the time of 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 of launching 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.After this structure is completely folding, becomes and tie closely shape, after fully launching to fix, reach initialization state, 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, mostly scissors hinges structure is to exist as vertical lifting device, and before utilizing scissors hinge structure to open and the huge difference on shape and height after opening, it has good lifting 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, there is circular development support larger folding ratio, based on 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 scissors unit, top circle, bottom scissors unit circle and junction plate, described scissors unit, top circle is formed by the mutual series connection of the first X-type connecting rod head and the tail pin joint, the 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 scissors unit, bottom circle is formed by the mutual series connection of the second X-type connecting rod head and the tail pin joint, the 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 is positioned on two different concentric circles of radius with the second pin joint point, the first described X-type connecting rod, the second X-type connecting rod and junction plate number are identical, described junction plate is arranged between described top scissors unit circle and scissors unit, bottom circle and is positioned at described concentrically ringed footpath upwards, the upper end of junction plate and scissors unit, top circle are at the first pin joint point pin joint, the lower end of junction plate and scissors unit, bottom circle are at the second pin joint point pin joint.
The outer end of described scissors unit, top circle and the outer end of scissors unit, bottom circle are on the circle of same Radius, and the length of described the first X-type connecting rod is greater than the length of the second X-type connecting rod.
Described junction plate is 48.
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 scissors unit, bottom is formed by pin pin joint by two blocks of bar shaped aluminium sheets, between scissors unit, bottom, respectively in end by pin pin joint together, after launching, forms an annular scissors unit circle; Same, scissors unit, Quan You top, scissors unit, top and pin pin joint form; Wherein, at the contact surface of pin and scissors unit, on the contact surface between scissors unit, all exist tetrafluoro backing plate; The lower end of a described rectangular aluminum sheet and scissors unit, top in the position of its two bar shaped aluminium sheet pin-connects together with scissors unit pin joint, the upper end of described rectangular aluminum sheet respectively with scissors unit, top in the position of its two bar shaped aluminium sheet pin-connects together with scissors unit pin joint.And pin joint point of every 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 rectangular aluminum sheet, and after supporting structure launches, the angle between every two rectangular aluminum sheet is 7.5 °, and the center extended line of all rectangular aluminum sheet points to the same center of circle.Fix a rectangular aluminum sheet every 90 °.
Beneficial effect: supporting structure of the present invention, adopt the junction plate between upper and lower two circle scissors cell pairs to launch and fold, and junction plate is arranged on the different concentric circles of radius from the pin joint point of upper and lower two circle scissors unit, not only can simply improve the folding ratio of junction plate, and while being deployed in arbitrary position, the position of junction plate is all the sensing home position of fixing.
