Fig. 8 is telescoping mechanism, bending mechanism, bindiny mechanism's installation relation schematic diagram.Bindiny mechanism 2 is mounted on telescoping mechanism
3 and 4 rear of bending mechanism, telescoping mechanism 3 and 4 upper and lower ends of bending mechanism same way is taken to arrange.
Fig. 9 is telescoping mechanism and bending mechanism the mount scheme schematic diagram between the fourth stage and level V.Telescoping mechanism 3 and curved
Mounting means of the bent mechanism 4 between the fourth stage and level V grade is different from prime, since level V vertex of a cone shell 1d is monoblock type,
Therefore telescoping mechanism 3 and bending mechanism 4 are installed in upper end in the same way, 3 conduct of telescoping mechanism without driving source is only installed in lower end
Follower.
Below with reference to the work of bionic Aircraft deformation nose cone device of Fig. 1-Fig. 9 descriptions based on marmem driving
Process.
For telescoping mechanism 3, under the driving of marmem, diamond shape bar group deformation, driving stock 3a ends drive
Public hinge axis 1f is moved；Since the C-shaped-rod 4a of bending mechanism 4 is in the constraint of radial direction, stock 3a ends can only be front and rear vertically
It is mobile, so that telescoping mechanism 3 can only change the axial position of public hinge axis 1f, realize pure flexible between adjacent nose cone shell
Movement.While telescoping mechanism 3 changes public hinge axis 1f axial positions, public hinge axis 1f drives C-shaped-rod 4a along track
4d axially movable, and keeps bending mechanism 4 and subordinate nose cone shell relative position relation constant compared with this grade of nose cone shell.
For bending mechanism 4, under the driving of marmem, diamond shape bar group 4b is deformed, under the constraint of C-shaped-rod 4a, next stage
Nose cone shell is rotated around public hinge axis 1f, so as to fulfill next stage nose cone shell compared with the inclined of this grade of nose cone shell
Turn.The co-operation of telescoping mechanism 3 and bending mechanism 4 makes deformation nose cone device integrally can be achieved flexible and unidirectionally be bent downwardly
Function.
For the second level to fourth stage nose cone shell, since it is divided into backboard shell 1b and web shell 1c, therefore upper and lower two
End is respectively equipped with telescoping mechanism 3 and bending mechanism 4, it is independently controlled respectively, bindiny mechanism 2 is in backboard shell 1b and abdomen
When relative motion occurs for plate shell 1c, its connection relation is still kept.For level V vertex of a cone shell 1d, since it is monoblock type,
A set of telescoping mechanism 3 and bending mechanism 4 is only needed to control it, therefore the telescoping mechanism 3 of lower end is only made without driving source
The intensity of device is improved for follower.
It is last it is to be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations.To the greatest extent
Pipe is with reference to the foregoing embodiments described in detail the present invention, it will be understood by those of ordinary skill in the art that：It is still
