Detailed description of the invention
Detailed description of the invention one, combine Fig. 1 to Fig. 8 present embodiment, unmanned plane gondola folding and retraction are described
Mechanism, forms including gondola 1, vibroshock 2, vibration isolation plate 3, guiding mechanism and telescoping mechanism；Described flexible
Mechanism is made up of motor 7, screw mandrel 4, screw mandrel leg 8, guide post 5, linear bearing 11, described motor
7 is through motor, and screw mandrel 4 passes from motor 7, and guide post 5 one end is fixed on screw mandrel leg 8,
The other end is arranged on vibration isolation plate 3 by linear bearing 11, and when motor 7 rotates, guide post 5 limits screw mandrel
The axial rotation degree of freedom of 4, there is axially opposing movement with 7, motor in screw mandrel 4.Guiding mechanism is by fixing
Frame 6, roller 10, roller shaft 9 form, and roller 10 constitutes matched in clearance, rolling with the guide rail of fixed support 6
Wheel shaft 9 is by hinged with screw mandrel leg 8 for roller 10, and roller 10 is compressed by screw mandrel leg 8 by roller shaft 9
Time on guide rail, roller 10 can occur relative roll thus guide roller axle 9 is along solid with fixed support 6
The guide rail motion of fixed rack 6.
Gondola 1 is fixed with vibration isolation plate 3 by vibroshock 2, vibration isolation plate 3 both sides and fixing in guiding mechanism
Support 6 hinged composition revolute pair, the motor 7 in telescoping mechanism is fixed by screws on vibration isolation plate 3；Stretch
Screw mandrel leg 8 in contracting mechanism is hinged by roller shaft 9 with the roller 10 in guiding mechanism；Telescoping mechanism is stretched
Contracting, forces vibration isolation plate 3 to rotate relative to the fixed support 6 of guiding mechanism, simultaneously drives the silk of telescoping mechanism
Bar leg 8 moves along fixed support 6, and action is packed up in the folding completing gondola 1.
There is pin shaft hole the both sides of the fixed support 6 described in present embodiment for hinged with vibration isolation plate 3, fixing
Guide rail 18 on support 6 moves for guide roller axle 9；The guide rail of fixed support 6 is involute shape guide rail,
The basic circle of involute is that motor geometric center 13 is with the electricity produced in vibration isolation Board position tag line 12 rotation process
Machine arc locus 15；Screw mandrel axis 14 is tangential on motor geometric center 13 with motor arc locus 15 all the time,
And doing pure rolling along motor arc locus 15, during this, the movement locus at roller shaft center 17 is gradually
Burst at the seams center line of guide rail 16；Screw mandrel axis 14 keeps vertical with involute center line of guide rail 16 moment, therefore,
Interaction force between each moment, motor 7 and screw mandrel 4 is all perpendicular to vibration isolation Board position tag line 12
With involute center line of guide rail 16 act on vibration isolation plate 3 and fixed support 6, this active force promotes vibration isolation
Plate 3 is swung up around the pin shaft hole of fixed support 6, and drive motor 7 and screw mandrel 4 are swung up therewith,
In vibration isolation plate 3, motor 7 and screw mandrel 4 swing process, the interaction between motor 7 and screw mandrel 4 is insisted on
Renew and maintain vibration isolation plate 3, motor 7 and screw mandrel 4 to be swung up around the pin shaft hole of fixed support 6.
Detailed description of the invention two, present embodiment are that the unmanned plane gondola described in detailed description of the invention one folds receipts
The assembling process of laying mechanism: realized by following steps:
Step one, screw mandrel 4 is assembled through motor 7, and by the end of screw mandrel 4 by screw thread and screw mandrel
Leg 8 connects.
Step 2, by motor 7 by four install screws be downwardly fixed on vibration isolation plate 3.
Step 3, be directed to bar 5 through linear bearing 11, and linear bearing 11 is pressed on vibration isolation plate 3 right
At the bearing mounting hole answered, the bottom being directed to bar 5 is threadably secured with screw mandrel leg 8.
Step 4, by roller shaft 9 through roller 10, and roller 10 is put in support bracket fastened guide rail, uses
Roller 10 is connected on screw mandrel leg 8 by roller shaft 9, and elasticity is maintained at permission roller 10 flexible rotating
State.
Step 5, vibration isolation plate 3 and fixed support 6 is hinged by the pin shaft hole on fixed support 6, complete
Overall assembling.
Step 6, the control line connecting motor 7 and power line, power supply makes screw mandrel leg 8 move to fixing
The bottom of frame 6 guide rail completes attitude and initializes.
Step 7, control motor 7 rotate and make motor 7 promote vibration isolation plate 3 to rotate 90 degree, complete to pack up gondola
The action of 1.
In present embodiment, when unmanned plane gondola 1 is in running order, screw mandrel leg 8 is in fixing
The bottom of frame 6 guide rail, vibration isolation plate 3 is in level relative to fuselage, gondola 1 relative to fuselage at
In plumbness；When working for electric drive motor 7, motor 7 promotes screw mandrel 4 to oppress leading of fixed support 6
Rail, motor 7 drives vibration isolation plate 3 to be swung up around the pin shaft hole of fixed support 6 under counteracting force promotes,
And screw mandrel 4 is swung up, drive roller 10 to roll in the guide rail of fixed support 6 upwards until fixing
The top of support 6 guide rail, now, vibration isolation plate 3 is in plumbness relative to fuselage, and gondola 1 is relative
Being in level in fuselage, complete gondola 1 packs up action.
