Detailed Description
The present invention will be further described with reference to specific examples, which are illustrative of the invention and are not to be construed as limiting the invention.
The working principle of the invention is specifically explained below: the fixed wing 21 and the foldable wing 22 are hinged together through a rotating shaft, the mounting plate 1 is fixedly mounted on the fixed wing 21, and the fixing plate 4 is fixedly mounted on the foldable wing 22.
When the foldable wing is folded and unfolded, the small motor 10 drives the small straight gear 8 and the small spiral gear 7 to move simultaneously, at the moment, the spiral gear 5 is driven to rotate on the rotating ring 303 of the locking plate 3, when the spiral gear 5 rotates to 90 degrees, the spiral gear 5 drives the locking plate 3 to rotate through the jackscrew 6, the fixing plate 4 is further driven to rotate, when the spiral gear 5 rotates to 180 degrees, the foldable wing 22 is unfolded and put down, and because the spiral gear 5 only keeps a gear of 180 degrees, the small spiral gear 7 and the spiral gear 5 are not meshed at the moment, and the locking plate 3 does not rotate any more; and because the small straight gear 8 only has one half of tooth surface, when the helical gear 5 rotates 180 degrees, the small straight gear 8 also just rotates one half without tooth surface, namely rotates 180 degrees, then the small straight gear 8 is meshed with the rack 9, drives the rack 9 to move in a translation way, and further drives the bolt 11 to move, because the bolt 11 is in a splayed shape, the bolt 11 is completely locked on the locking plate 302, and the rotation of the following 90 degrees (270 degrees in total) is continuously completed to complete locking.
When unfolding and folding, little motor 10 antiport, the opposite direction motion of little straight-tooth gear 8 drive rack 9, make spring bolt 11 leave locking plate 302, little spiral gear 7 can reverse mesh drive spiral gear 5 under little spring 14 effect this moment, because spiral gear 5 sliding tray exists, in the rotation of preceding 90, locking plate 3 is not driven and rotates, and then after spring bolt 11 deviates from completely, spiral gear 5 passes through 6 reverse drive locking plate 3 of jackscrew, and then drive fixed plate 4 and fold 90 degrees, then little straight-tooth gear 8 is not at the meshing rack, and little spiral gear 7 also does not mesh spiral gear 5, but this moment need continue to rotate 90 degrees (270 degrees in total) accomplish a circulation can.
