Description
Technical field
The invention belongs to space industry, and in particular to a kind of deployable shading closure assembly.
Background technology
Space optics telescope and remote sensing camera are required for light shield to realize suppression and the camera temperature control of veiling glare
Function.At present, conventional light shield takes stationary structure, it is impossible to collapsible, and this kind of light shield of form is suitable for small
The space optical camera of bore；As space optical camera develops towards big visual field, high-resolution direction, the bore chi of light shield
Very little increasing, traditional fixed light shield has not been suitable for the development of large-caliber space optical system, simultaneously because rocket
The limitation of radome fairing size, large-sized light shield cannot be positioned in rocket radome fairing, in the urgent need to possessing deployable function
Light shield form.
The content of the invention
In order to solve problems of the prior art, the invention provides a kind of deployable shading closure assembly, by hiding
The collapsible technology of light shield, effectively reduces the axial dimension of camera load, so as to overcome rocket fairing length size
Limitation；Seal assembly is driven to realize the leakage problem that the shading wall after launching is overlapped out using inflation.
The technical proposal for solving the technical problem of the invention is as follows：
A kind of deployable shading closure assembly, the device includes：The pedestal of prism structure, the screening for being arranged on pedestal upper surface side
Light wall component and the inflation being arranged on pedestal incline drive seal assembly；It is multiple screenings before the shading wall component operation
Light wall is folded with by the way that torsion hinge is Z-shaped, and during work, shading wall component is by the strain energy of torsion hinge into plane
Structure, by inflating the fixation and sealing that drive seal assembly to realize multiple shading wall components.
The beneficial effects of the invention are as follows：The present invention is made up of shading wall component, and seal assembly is driven by screening by inflating
The clearance seal of lap-joint after the expansion of light wall component, so as to constitute a closed shading cover structure in border, prevents light leak, dissipates
The generation of heat.

Specific embodiment
The present invention is described in further details with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of deployable shading closure assembly includes：Pedestal 1, shading wall component 2, inflation drive sealing group
Part 3；Wherein, shading wall component 2 is made up of torsion hinge 4 and shading wall 21, is connected solid with pedestal 1 by torsion hinge 4
It is fixed；Inflation drives seal assembly 3 by velcro 31, carbon fiber cambered surface band 32 and polyimide flex inflation valve for spreading 33 structures of cylinder
Into.
Pedestal 1 is the matrix of total, is six prism structures, and sealing is driven for fixing shading wall component 2, inflation
Component 3 etc., it uses titanium alloy integral casting forming；Every one side of the upper surface of six prism pedestal 1 connects one group of sailboard type shading
Wall component 2.The lap-joint of every group of sailboard type shading wall component 2 connects a set of inflation and drives seal assembly 3 respectively.
As shown in Fig. 2 shading wall 21 is when collapsible, the storage strain energy of torsion hinge 4, the strain energy is realized
The shading wall component 2 of compressive state is launched into planar structure.
Six groups of shading wall components 2 form a shading tubular construction for six prisms after launching, due to every group of shading wall
There is gap in the lap-joint of component 2, it is therefore desirable to encapsulation process is carried out using 3 pairs of gaps of inflation driving seal assembly, such as Fig. 3 institutes
Show.
As shown in figure 4, inflation drives seal assembly 3 by velcro 31, carbon fiber cambered surface band 32, polyimide flex
Inflation valve for spreading 33 grades of cylinder are constituted, and velcro 31 is bonded and fixed on the crooked inner surface of carbon fiber cambered surface band 32, and polyamides is sub-
Amine flexible gas-filled stretches cylinder 33 and is bonded and fixed on the crooked outer surface of carbon fiber cambered surface band 32；The inflation drives seal assembly
3 can wind, and it is connected in air inlet end entrance 331 with pedestal 1, and winding end is locked before transmission, after entering the orbit, volume
Linear state can be constantly launched into, due to also being sticked on two groups of shading wall components 2 in the presence of driving force is inflated around end
Velcro is posted, therefore with the continuous expansion at winding end, spread is consolidated by velcro 31 with shading wall component 2
It is fixed, it is achieved thereby that after shading wall component 2 launches lap-joint encapsulation process, form the closed light shield knot in a border
Structure.
Before transmitting, the deployable shading closure assembly compression is fixed, as shown in figure 1, after entering the orbit, the deployable light shield dress
The expansion dynamic process put is as follows：As shown in Fig. 2 first, shading wall component 2 unlocks, in the driving of torsion hinge 4
Under, into deployed condition；Secondly, inflation drives seal assembly 3 to unlock, and in the presence of driving force is inflated, winding end is continuous
Launch, as shown in Figure 3 and Figure 4, and fixed with corresponding shading wall component 2 by velcro 8.
Shading wall 21 is made by aluminum honeycomb material, and inner surface carries out disappear veiling glare treatment, outside using spray black lusterless paint
Face can carry out pasting heating sheet mode etc. and carry out thermal control implementation；The torsion hinge 4 driven based on torsionspring can be by interior
The strain energy of portion's storage realizes self-deploying for shading wall component 2, without external motivating force.Screening after velcro 31 and expansion
The velcro of light wall 22 is fixed, and realizes the encapsulation process of light shield；Carbon fiber cambered surface band 9 uses high-strength carbon fiber system
Make, with good toughness, elasticity, the support frame of seal assembly 3 can be driven as inflation；Polyimide flex inflation is stretched
