The present invention is further described for explanation and specific embodiment with reference to the accompanying drawing.
As shown in Fig. 2 (a), Fig. 2 (b) and Fig. 2 (c), cube star of the invention compresses the state that release device assembles, whole
Body is a small-sized Square barrel open at one end, and the corresponding surface of open end is locking and relieving mechanism, does not install a cube star in bucket
When, release spring is free state.Fig. 3 is the apparent size that cube star of the invention compresses release device.
Fig. 4 is that cube star is mounted on the schematic diagram compressed in release device, and Fig. 5 is Teflon latch segment in pressure of the invention
Perspective view in tight release device.The top fixed structure of release device is compressed mainly by being mounted on four spies on cube star top
Fluorine dragon latch segment composition.The Teflon latch segment for being placed in cube star top possesses multifunctional usage: 1. Teflon latch segment can be inhaled
Receive the vibration during satellite launch；2. due to the cushion block, so that four faces of cube star are with generating 3 millis between separator structure
Rice gap, generates between star and separating mechanism to avoid cube and collides with, and protects cube star catalogue face cell piece；3. can effectively lock
Tight cube of star one end reasonably selects the tilt angle of Teflon latch segment, it can be ensured that the reliability of cube star separation.

About 500N) locking when, may make a cube star be put into compress release device when can efficiently and easily opposed middle fixation, with solution latch
It engages and carries out locking program.
To realize straight line separation, the Teflon actor playing a supporting role is increased between spring and cube star, this component make the bottom plate of cube star with
Spring being capable of average force when being liberated.As shown in fig. 6, Teflon actor playing a supporting role's shaft section is designed as outer hexagon, such Teflon axis
Set is smaller with outside aluminium sheet contact surface, greatly reduces its mutual frictional force.In order to guarantee with the flat of cube star contact
Face is also able to maintain vertical state under any circumstance, and component is purposely remained certain length when designing.Teflon and aluminium
The coefficient of friction of material is smaller, though in the case that have close to also will not on the function of spring constitute influence, only can be in detaching direction
There is deflection angle, separation process will not be impacted.
Unlocking mechanism is the key that entire separator reaches task object branch point；In locking state, solution lock machine is utilized
Unlock ox head in structure conciliates lock, and separator can lock a cube star.Fig. 7 is the lock ox head schematic diagram of unlocking mechanism, and Fig. 8 is
The solution locking plate schematic diagram of unlocking structure solves the tolerable unlock ox head of aperture on locking plate in each 15 degree of the range of tolerable variance in left and right

Unlocking ox head is circle contact surface with the contact for solving locking plate.Compare with common flat contact surface, circle contact surface meeting
It enables the stress of locking buckle structure stronger and rotational action can be allowed more smooth, can also make to unlock ox head and solve in locking plate in insertion to have
The advantages of automatic guide.The contact surface for unlocking ox head reconciliation locking plate applies MoS2Coating, torque needed for can reducing rotation, can also
Avoid the caused adhesion that rubs, the reliability of lifting device.
Too big stress is born in unlock ox head axle center when to avoid vibration, axis diameter need it is bigger than the area of contact surface, this
Axle center is caused to misplace by friction effects when the design of sample can also eliminate rotation.
When a cube star is assembled in separating mechanism, driving motor power supply compresses release device starting locking program, and turns
After dynamic 90 degree of ox head of unlock, cube star can be fixed.Fig. 9 gives action process of the solution lock reconciliation locking plate in separation.
Unlock ox head can only rotate counterclockwise in design.Under normal journey condition, since tripper has ratchet mechanism,
Even if taking a turn for the worse, separating mechanism will not be acted.After satellite launch lift-off, driving mechanism is driven by rocket, and power supply is opened again
Dynamic, the rotation of motor drives unlock ox head, and lock ox head and solution locking plate perforation are to timing two pieces component meeting after unlock operation starting
With separate, realize the separation of cube star.
Cube star compresses release device and assembles in complete independently；Release device is compressed without in the state of dismantling master unit
A cube star can be fixed.In fig. 8 it can be seen that unlock design of gears has the aperture of different-diameter, pore size is by rule
Distribution nearby can be observed deliberately to be added in the aperture on unlock buckle teeth wheel in isolated end motor, according to estimating not
Same aperture, can determine the current position of gear and rotation direction.
Figure 10 illustrates the interior design of unlocking mechanism.Spine when one of motor stops operating, in unlocking mechanism
Wheel clutch can play a role, and prevent entire mechanism from can not unlock because single-motor stops.
The brush direct current motor driving that the driving mechanism of unlocking mechanism is manufactured by Liang Ge Switzerland forms, and two motors move simultaneously
Make, while problem occurs for such as one motor of any of them, another motor can also undertake all unlocking programs by one's own efforts.
