Detailed description of the invention
Below the present invention is described in further detail. Referring to Fig. 1, Fig. 2, a kind of aircraft cockpit solar protection devices, it is made up of sunshading board 11, photochromic sun film 10, rotating shaft 7, major axis set tooth 8, servo-actuated stop collar tooth 4, spring 3, short sleeve tooth 5, position-limitting pin 6, sleeve 9 and screw 1, it is fixed in decomposition driving cabin endogenous wind by mounting seat 2 and blocks portion, be that a set of crew can keep off, according to driving cabin front windshield or crosswind, the rotating mechanism that sun-shading requirements is adjusted. A kind of photochromic sun film 10 packaging by hot pressing suitable with sunshading board 11 size is within sunshading board, sunshading board hot-press solidifying overlaps on tooth 8 at major axis, rotating shaft 7 overlaps tooth 8 through major axis, it is meshed with servo-actuated stop collar tooth 4, and it is assemblied within sleeve 9 together with spring 3, screw 1, in sleeve 9 precession rotating shaft 7, makes major axis set tooth 8, and servo-actuated stop collar tooth 4, spring 3 and sleeve 9 complement each other to form the solar protection devices 7 rotatable governor motion of level rotated around the shaft; Spring 3, servo-actuated stop collar tooth 4, short sleeve tooth 5 are assembled together and are placed within mounting seat 2, and position-limitting pin 6 coordinates through hinge hole and the mounting seat 2 of rotating shaft 7 with screw 1, form the vertical rotatable governor motion of solar protection devices. This solar protection devices on-demand can stably rest on desired location to meet the sun-shading requirements of crew.
The operation principle of the present invention is: when needs sunshade, crew's manual overturning sunshading board makes it around horizontal axis, now, major axis set tooth 8 has the trend that actuating sleeve tooth 4 rotates, and overlap tooth under rotating the constraint of rectangular boss of axle 7, rectilinear motion can only be done, cause that spring 3 is compressed, major axis set tooth 8 is made to disengage with set tooth 4, thus realizing the upset of sunshading board; When sunshading board is inverted to desired suitable location and stops operating, under the pressure-driven of spring 3, set tooth 4 overlaps tooth 8 to major axis and moves, and makes the two set tooth again engage each other, it is achieved the location of sunshading board and locking. Simultaneously, solar protection devices has similar motor adjustment, locking mechanism around rotating of its vertical axis to around its horizontal axis, to realize the orientation adjustment of solar protection devices, as put from front windshield position adjustments to crosswind gear, or rightabout adjustment, reach the purpose of aircraft cockpit front windshield and the on-demand sunshade in crosswind gear place.
