14 thrust is bonded with sun gear 25.At this point, shaft 31 and sun gear 25, which generate constraint, directly transmits power.
Under traction state, when internal gear 30 has anticlockwise rotation trend relative to shaft 31, ball holdback
32 in being freely rotated state.When 34 drive shaft 31 of stepper motor rotates clockwise, sun gear 25 is rotated clockwise.At this time
Idle gear 29 rotates counterclockwise, so that internal gear 30 be driven to rotate counterclockwise.As shown in Figure 4 under such state, 30 phase of internal gear
To the anticlockwise rotation of shaft 31, ball holdback 32 is functionally equivalent to bearing.That is the rotation of internal gear 30 is not by shaft
31 interference.
Sun gear 25 at this time, idle gear 29 and internal gear 30 constitute a deceleration transmission system, play and turn to stepper motor 34
Speed slows down, the increased effect of torque.At this point, the spiral slot of internal gear 30 winds cable 4, until piston component 8 enters gas chamber
In the piston cylinder of seat 36.Traction damper 3 is launched during this is in traction state work.
Referring to figure 5., when traction finishes, piston component 8 in place when, system initially enters ejection preparation state.Stepping electricity
Machine 34 is shut down, and electromagnet 13 is still in off-position.The mini air pump movement of control system control at this time, toward gas chamber shell 11
Inflating port inflation.Piston component 8 is generated down thrust by air pressure, pulls cable 4 to move downward, to drive internal gear 30 suitable
Hour hands rotation.At this point, idle gear 29 rotates clockwise, sun gear 25 is driven to rotate counterclockwise.Due to sun gear 25 and shaft 31
By the constraint of transfer strip 23, to rotate counterclockwise.At this point, internal gear 30 is rotated clockwise relative to shaft 31, ball is inverse
Only device 32 is in locking state, that is, hinders the generation of this rotation, to realize that complete machine is self-locking, i.e. obstruction piston component 8 pops up.
Fig. 6 is please referred to, when the indoor air pressure of gas reaches specified value, ejection can be carried out and arrest illegal unmanned plane.Work as mother
When machine 1 is flown to above illegal unmanned plane, ejection is carried out to it and is arrested.Control system issues life to ejection traction damper 3 at this time
It enables, stepper motor 34, which is passed through, keeps electric current locking.Electromagnet 13 is powered.It should be appreciated that stepper motor 34 is passed through holding electricity herein
After stream, there is the output shaft that the effect of " locking " can be understood as stepper motor 34 one to keep the maintenance energy not rotated, when
When external force forces output shaft to rotate, need to overcome the reactive torque of maintenance energy generation.
So the kinetic energy of lower frame component 6 is just anti-with this under the energization of stepper motor 34 maintains the lock status and when launching
It is that damping gradually uses up to torque.When the damping is greater than the gravity of lower frame component 6, it can make lower frame component 6 after pop-up
Do retarded motion.
When electromagnet 13 is powered, armature 12, which moves to left, drives transfer strip 23 to move to left, and makes the flank of tooth and sun gear 25 of transfer strip 23
The flank of tooth separation.Shaft 31 and sun gear 25 in this way loses constraint, can do non-interference rotation.
Piston component 8 is pulled cable 4 to move downward, so that internal gear 30 be driven to rotate clockwise by downward thrust.
At this point, maintain the lock status since stepper motor 34 is in be powered, thus shaft 31 has the maintenance energy for maintaining not turn.Therefore in
The trend that there is gear 30 opposite shaft 31 to operate clockwise.Ball holdback 32 is in locking state as a result, that is, needs to overcome
The reactive torque of the maintenance energy of stepper motor 34 is just able to rotate.Since the tractive force of cable 4 when lower frame component 6 flies out is greater than stepping
The reactive torque of motor 34, therefore shaft 31 rotates clockwise.
When internal gear 30 rotates clockwise, idle gear 29 is rotated clockwise.To drive sun gear 25 to rotate counterclockwise.
Due to losing the constraint of transfer strip 23, the shaft bearing 24 between sun gear 25 and shaft 31 only plays the smooth work of relative rotation
With.Therefore on the damping action of system without influence.
