Embodiment
Embodiment one：Illustrate present embodiment, closure described in present embodiment with reference to Fig. 1 to Fig. 5, Fig. 7
The non-contact type lock of magnetic circuit one side permanent magnetic steel structure, it includes stator and rotor, one of them and equipment to be locked
Moving component is assembled together, and the stationary parts of another and equipment to be locked is assembled together；
Stator includes stator yoke 2 and two pieces of permanent magnetic steels 3；Stator yoke 2 is by one piece of rectangular base plate and two pieces of rectangle riser structures
Into two pieces of rectangle risers are set in parallel in the upper surface of rectangular base plate, and vertical with rectangular base plate, form U-shaped frame structure, U-shaped
The penetrating direction of frame is the axial direction of stator；One piece of permanent magnetic steel 3 is set respectively in the inner surface relative position of two pieces of rectangle risers,
Stator pilot hole 4 is symmetrically arranged with rectangular base plate between the outer surface and rectangular base plate outward flange of two pieces of rectangle risers；Two
Block permanent magnetic steel 3 is parallel magnetization, and magnetizing direction is identical, and parallel with two pieces of lines of centres of permanent magnetic steel 3；Permanent magnetic steel 3
Axial cross section is circle；
Rotor includes rotor yoke 1, and rotor yoke 1 is rectangle revolving body, and the top half of rotor yoke 1 is provided with rotor pilot hole
5, the axis of rotor pilot hole 5 is parallel with two pieces of lines of centres of permanent magnetic steel 3；Rotor yoke 1 is carried out with rotor pilot hole 5 for fulcrum
Revolution moves back and forth, and the lower end movement locus of rotor yoke 1 passes through the penetrating direction of U-shaped frame, and the lower end of rotor yoke 1 is itself and permanent magnetic steel
3 coupling surface, the width of the coupling surface are equal with the width of permanent magnetic steel 3；
When needing lock operation, borrow external force and moving component is moved to ' locked ' zone so that rotor yoke 1 leads in U-shaped frame
Saturating direction is done revolution and moved back and forth, when the coupling surface of rotor yoke 1 just aligns with two pieces of permanent magnetic steels 3, at stator and rotor
In equilbrium position, the moving component and stationary parts of equipment to be locked are locked in together.
The polarity of two pieces of opposite faces of permanent magnetic steel 3 is different.
Rotor yoke 1 and stator yoke 2 are made of steel material.For magnetic conductive material.
Rotor yoke 1 can be moved around the centre of gyration, and stator yoke 2 axially makes U-shaped frame structure, to avoid
With the movement interference of rotor yoke 1.
Present embodiment has two kinds of assembly methods：
The first assembly method：Rotor is assembled together by the moving component of rotor pilot hole 5 and equipment to be locked, fixed
Son is assembled together by stator pilot hole 4 and the stationary parts of equipment to be locked.
Second of assembly method：Rotor is assembled together by the stationary parts of rotor pilot hole 5 and equipment to be locked, fixed
Son is assembled together by stator pilot hole 4 and the moving component of equipment to be locked.
When that need not lock, stator and rotor are placed on two positions, then the coupling surface and permanent magnetic steel of rotor yoke 1
3 are not present coincidence face, and no magnetic circuit is by that will not lock.
When needing locking, borrow external force and moving component is moved to ' locked ' zone so that rotor yoke 1 is penetrating in U-shaped frame
Direction is done revolution and moved back and forth, and is exactly just with determining in circumferencial direction lock rotor yoke 1 when moving to position shown in Fig. 3
Position when sub- permanent magnetic steel 3 aligns, this is locked out stable equilibrium position when device is in the lock state.Due to two blocks of permanent magnetism
The polarity of magnet steel 3 is different, and the coupling unit of stator yoke 2 and rotor yoke 1 is magnetic conduction, so the closure now formed
Magnetic circuit is as shown in Fig. 2 magnetic field is most strong.Because the polarity of two pieces of permanent magnetic steels is different, and stator yoke and rotor yoke
Coupling unit be magnetic conduction, so N pole → air gap → rotor yoke 1 → right side permanent-magnet magnetic of the magnetic field according to left side permanent magnetic steel 3
The N poles of S poles → left side permanent magnetic steel 3 of the N poles of S poles → right side permanent magnetic steel 3 of steel 3 → 2 → left side of stator yoke permanent magnetic steel 3
Order formed closure.Because rotor yoke 1 does not have permanent magnetic steel above, so moving out stator component coupling model in rotor part
After enclosing, magnetic disturbance will not be produced to the miscellaneous equipment of surrounding.
In this equilbrium position, if due to certain disturbance, make motion parts produce a drift angle, as shown in figure 4, then due to
The magnetic line of force bends, and stator component can produce a restoring moment to rotor part, be returned to the initially position without drift angle.
Within the specific limits, drift angle is bigger, and restoring moment is bigger.When drift angle reaches certain numerical value, righting moment can reach peak value.
Behind this drift angle, because the permanent magnetic steel 3 of stator and the coupling area of rotor yoke 1 are less and less, restoring moment is also more next
It is smaller.After drift angle continues to increase to certain numerical value, as shown in figure 5, magnetic steel of stator and rotor yoke almost do not couple,
It is approximately zero that restoring moment, which is reduced to, it is believed that lock is without any locking action.
The torque characteristic of lock is as shown in Figure 6 in whole sphere of action.Characterize the main finger of lock performance
Mark is exactly peak torque Tm, maximum lock angle θ m and critical tri- parameters of lock angle θ r.
Embodiment two：Illustrate present embodiment with reference to Fig. 6, present embodiment is made into one to embodiment one
Step explanation, the lower end of rotor yoke 1 is circular arc；The upper end of two pieces of rectangle risers is circular arc in stator yoke 2.
When being made an engineering product, the end portion of stator yoke 2 and rotor yoke 1 can make circular shape, so as to
In loss of weight and reduce movement interference.
Embodiment three：Provide a specific embodiment, lock rotor radius of gyration 0.10m（Assembled from rotor
The length of hole 5 to the bottom of rotor yoke 1）, the width 10mm of side, the diameter of the permanent magnetic steel 3 of stator where the coupling surface of rotor yoke 1
10mm, unilateral air gap 1.5mm.The peak value locking torque that lock is finally calculated is 0.77Nm, and maximum lock angle is 7.5
Degree, critical lock angle are 3.4 degree, have reached expected design effect.
