Abstract
The invention relates to a large-sized keel type non-intrusive lens hood and belongs to the space optical remote sensing technical field. The lens hood includes a front lens hood, a side envelope, a keel and flexible supports; the front lens hood is installed at the upper surface of the keel; the side envelope is installed at the side surfaces of the keel; and the flexible supports are installed at the bottom ends of the four corners of the keel. According to the large-sized keel type non-intrusive lens hood, a keel type structure is adopted to replace a barrel structure, so that the problems of difficult machining and high cost of a large-sized lens hood mould can be solved; when the barrel structure is adopted, an integrated mould is needed to be manufactured, while, when the keel type structure is adopted, only moulds for an envelope substrate and a square tube are required to be manufactured, and the manufacture process of the moulds for the envelope substrate and the square tube is superior to that of the integrated mould, and therefore, the machining process of the lens hood can be simplified, and cost can be reduced; the flexible supports are adopted to replace rigid ring-shaped connectors, and therefore, the problem of disturbance on an optical lens caused by the lens hood can be solved; the flexible supports can absorb assembly stress caused by lens hood machining error and deformation through the deformation of the flexible supports, and therefore, the stability of the optical lens can be ensured, and imaging quality can be improved.
Description
Technical field
The invention belongs to space optical remote technical field, relate to a kind of large scale keel type without immunity shadingCover.
Background technology
Light shield is the important component part of space optical remote sensor, and its Main Function is extraneous spuious for reducingThe impact of light on remote sensor image quality. It is to carry out primarily arranging of veiling glare inhibition that light shield is reasonably setExecute, it directly shield portions gas light and other veiling glares enter remote sensor camera lens, can utilize again its tableThe inner diaphragm arranging of face material behavior and light shield absorbs the veiling glare that enters light shield, fromAnd the signal to noise ratio of raising remote sensor.
At present, large space optical sensor light shield adopts the carbon fibre composite that density is less mostly,Version is generally integrated barrel-like structure, and light shield bottom is provided with ring interface, by annularBeing rigidly connected of Interface realization and optical lens agent structure. This structure has following shortcoming:
1) moulding difficulty is large. Adopt the structural member of carbon fibre composite, generally by mould molding, largeType space optical remote sensor light shield volume is large, and complex structure, as adopted barrel-like structure, needs to make entiretyMould, there is larger difficulty in design, the processing of mould, and because light shield belongs to thin-wall construction part, de-Yielding after mould, dimensional accuracy is difficult to meet the demands.
2) cost is high. The light shield of barrel-like structure will be realized one-body molded, needs to make unitary mould, due toShading cover structure complexity, its unitary mould structure is inevitable also very complicated, the design of mould, processing cost meetingVery high, even can be higher than the cost of light shield itself.
3) process-cycle is long. The process-cycle of light shield is divided into two stages, and the one, the process-cycle of mould,The 2nd, the process-cycle of light shield itself, mould is more complicated, and its process-cycle is longer, whole light shieldProcess-cycle is also just longer.
4) easily camera lens is produced to disturbance. Compared with hardware, carbon fiber composite structure partDimensional accuracy is relatively poor, and easily distortion after moisture absorption, adopts ring interface and the optical lens master of rigidityBody structure connects, and is easy to unevenness and self-deformation to be delivered on optical lens, and optical element is producedGive birth to relative displacement, thereby affect the image quality of camera.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of large scale keel type unperturbedProperty light shield, this light shield moulding is easy, with low cost, undisturbed.
The technical scheme that technical solution problem of the present invention adopts is as follows:
Large scale keel type is without immunity light shield, and this light shield comprises: front light shield, side skin, keelAnd flexible support; Front light shield is arranged on the upper surface of keel; Side skin is arranged on the side surface of keel;Flexible support is arranged on the bottom of four jiaos of keel.
The invention has the beneficial effects as follows: the present invention adopts keel type structure to substitute barrel-like structure, solved largeSize light shield Mould Machining difficulty, the problem that cost is high, barrel-like structure need to be made unitary mould, dragonBone formula structure only need to be made the mould of covering substrate and square tube, and manufacture craft is better than unitary mould, fromAnd the processing technology of light shield is simplified, cost; Adopt flexible support to substitute rigid annular shaped interface,Solved the perturbed problem of light shield to optical lens, flexible support has absorbed light shield by self-deformationThe erection stress that mismachining tolerance and distortion bring, thus the stability of optical lens ensured, improve one-tenthImage quality.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further details.
As shown in Figure 1, large scale keel type unperturbed light shield includes front light shield 1, side skin 2, dragonBone 3 and flexible support 4.
As shown in Figure 2, front light shield 1 is by front light shield covering 5, front light shield diaphragm 6 and front shadingCover flange 7 forms, and front light shield diaphragm 6 and front light shield flange 7 are solid by modes such as splicing, riveted jointsFix on front light shield covering 5, front light shield 1 is fixed on keel 3 by front light shield flange 7.
As shown in Figure 3, side skin 2 is made up of covering substrate 8, diaphragm 9 and reinforcement 10, diaphragm 9,Reinforcement 10 is fixed on covering substrate 8 by modes such as splicing, riveted joints, and 9 of every two diaphragms are all pacifiedFill multiple reinforcements 10 vertical with diaphragm 9.
As shown in Figure 4, keel 3 are to be connected 12 hexahedrons that form, square tube 11 with angle by square tube 11Be connected 12 with angle and link together by the mode of glueing joint and pin connects, bonding mode is socket. As figureShown in 5, square tube 11 inwalls are inlaid with plate nut 13, for front light shield 1 and side skin 2 are installed.
