Description

The electric mechanical switch that magnetic loads

Technical field

Embodiments of the present invention are usually directed to electric mechanical switch and Operation & use method thereof.More particularly, embodiments of the present invention relate to and can utilize switching device to control the device of flow element, pneumatic element, electric component, mirror elements (mirror element) and optical element and the method for controlling flow element, pneumatic element, electric component, mirror elements and optical element by manipulator electric switch.

Background technology

Electronically controlled switch utilizes the Electromagnetic Design of some forms to produce the change for the state of application-specific.These designs generally include for electronically controlled coil, contribute to close or open the spring at control point and for the multiple design at control point.Control point for switch in electrical applications normally comprises contact, and the port holes with plugging (plugging) mechanism of some forms is for Fa control point, and lens subassembly is the control point for optical switch.

The operation of traditional switch is usually directed to the use at core direct solenoid around, and when energy being increased to coil or remove from coil, it opens or closes valve.Some MEMs(MEMS (micro electro mechanical system)) design utilizes cavity extrusion effect, thus energy is applied to the closure that piezoelectric causes cavity or barrier film.

At present, spring and linkwork design contribute to the operation of the switch of use in valve application conventionally.Some switches have port holes, and it is sealed by compliant materials being arranged in to port holes top.Unfortunately, these springs and linkwork are arranged in extra load demand in this structure.For overcoming these demands of spring and linkwork, need higher magnetic force to operate this switch.

In addition, switch is often worn and tears.For example, many valve seats all have the spicule of cone shape, make the seat that inserts cone shape will cause sealing.In these designs of great majority, any misalignment being occurred by intrinsic manufacturing tolerance all must be by compensating with relatively strong spring, forcibly valve design is pushed in the situation of locating completely.Misalignment also may cause in the leakage at valve seat place or the combination of mechanical structure.

Each in these situations has all been arranged additional demand and has been increased manufacturing cost on electromagnet.In addition, for the valve material that seals, under load condition, this has increased wearing and tearing by the operation increasing.From cost angle, it is desirable to be limited in the material using in switch.More particularly, the conductor using in switch is made by being tending towards the expensive high conductance material such as copper or aluminium conventionally.Maybe advantageously reduce material (at least at size and/or quantitative aspects), energy and the cost using, keep or increase simultaneously the performance of the switch that comprises electric mechanical switch.

Embodiment

Embodiments of the present invention relate to the switch that comprises electric mechanical switch, its compactness, reliable, operation fast, can and/or demonstrate long operation lifetime with low cost fabrication.From cost, energy and dimension point, at least compare with traditional switch, and embodiments of the present invention reduce or minimized the structural requisite on switch.For example, reducing the quantity that loading demand in electromagnetic switch contributes to be used in the required ampere circle of the electromagnet in console switch minimizes.Advantageously, can also reduce the quantity of the required material of switch.In addition, embodiments of the present invention relate to a kind of switch, and it needs low-down operating energy and has the number of components of reducing.

Switch disclosed herein or switching device (comprising electric mechanical switch) at least can use in fluid application, electrical applications, aerodynamic applications, speculum application and/or optical application.Conventionally, electric mechanical switch adds carrier material with magnetic in plunger structure and forms by being arranged in ring.Then, attached coil is to be provided for the magnetic field of installation switching device.

Fig. 1 shows the stereogram that comprises switching device of switching device 100 and an example of end view.Switching device comprises body 102, and it comprises core 104 and housing 106.In an example, for core 104 and the material of housing 106, comprise the material of the material that magnetic material maybe can be magnetized, such as the plastic plastics of the injection moulding that comprises magnetic material.Alnico alloy, neodymium, SmCo are the examples of material.Conventionally can be according to the material behavior of expectation by injection mo(u)lding polymer-filled to percentage.

Housing 106 has outer surface or the periphery that shape can change.For example, the shape of outer surface can change according to the use of switching device 100.Outer surface (with further feature) can form the specific location that fits in device or product.

Housing 106 normally comprises that shape is designed to hold the cavity 118 of core 104.Normally, cavity 118 has circular cross section and core 104 has circular cross section.The cross section of core 104 is less than the cross section of cavity 118 conventionally, therefore allows core 104 to fit in cavity 118.

Alternatively, the relation between housing 106 and core 104 can adopt other structure.In an example, housing 106 can be the ring-type with the cavity 118 can core 104 taking.In this example, core 104 can be considered as substantially filling up the plunger of housing 106 hole or cavity 118.Yet as shown in Figure 8, core is filled chamber but be allowed to can laterally translation in cavity by halves.More particularly, the length of core 104 can change with respect to the length of cavity 118.As more described in detail here, different length can be used to realize or or a plurality of different state of switching device 100.

Yet, housing 106 the cross-sectional area at cavity 118 places substantially core 104 fill up, therefore core 104 can be regarded as plunger in this sense.As here more described in detail, core 104 can be at the interior transverse shifting of cavity 118.Core 104 can have be less than cavity length, be greater than the length of cavity or equal the length of cavity.

In the execution mode of alternative, the relation between the cavity in housing 106 and the external shape of core 104 can change and be not corresponding each other.For example, cavity 118 can have cone shape separately with core 104.In another example, cavity 118 can be columniform or tubulose, and the shape of core 104 can be part tubulose or cylindrical and part is conical.The tubulose of core 104 or cylindrical part can make core 104 remain in cavity 118 directly, and the conical portion of core 104 can be as the point of the control of switching device 100.Core 104 all has from first end separately to the transformable cross-sectional profiles of the second end separately with cavity 118, and wherein cross-sectional profiles mates to allow relative to each other to rotate.

The shape of the cavity 118 in housing 106 and the shape of core 104 allow core that non-contact type interface is provided, and make the switch at least one execution mode can be sealed in contactless situation.For example, core 104 and housing 106 are configured to allow core in the interior rotation of cavity 118.Therefore the surface of core 104 vicinity limits the inwall of the housing of cavity 118.Yet, core 104 and housing 106 magnetic field, allow core 104 according to magnetic pole to directly.As explanation in further detail below, only by the mode of example non-exclusively, this allows switching device 100 to provide contactless sealing in fluid and aerodynamic applications.

Advantageously, magnetic field can be configured to provide essentially no contact interface.As described below, around the periphery of core 104, present gap 116.Contactless interface between core 104 and housing 106 allows core 104 in housing 106 (or in cavity 118) to rotate with substantially less friction.

The definite utmost point (aligning poles) 108 of aiming in symbol north (N) in Fig. 1 and Fig. 2 and symbol south (S) makes their own natures ground directed to core 104 with housing 106 bases.The switch of Fig. 1 in showing in the raw, the magnetic pole of its SMIS 104 attracted to the respective poles of housing 106.In nature, the common no power of switching device 100.

Fig. 1 also illustrates switching device 100 can comprise the armature 112 with coil 100.Armature 112 and/or coil 110 are fixed on the housing 106 of switching device 100 conventionally.By the mode of example, this connection can be machanical fastener (such as screw, bolt), epoxy resin part, weldment etc.Armature 112 is examples of power device with coil 110.Power device can be controlled the cavity Nei position of core in being formed at housing.Only by the mode of example, can be rotatably and/or laterally control this position.

In an example, armature 112 and/or coil 110 can comprise the lid being configured to the engaged at end of housing 106.Housing 106 can have the groove that engages with complementary structure in lid or other structure with by lid and thus coil 110 be fixed on appropriate position with armature 112.Complimentary engagement structure can also have rotational structure to guarantee that armature 112 is correct with respect to core 104 with the layout of housing 106, thereby guarantees the proper handling to switching device 100.Armature 112 can also be attached on housing 106 by being arranged in pressure sensitive adhesives between housing 106 and armature 112, UV cured binders etc.

When coil 110 energising, just can in armature 112, form the arctic and the South Pole 114.The magnetic force being produced by coil 110 is preferably designed to overcome core is remained on to required magnetic energy in its nature 104A.As shown in Figure 2, when coil 110 energising and armature 112 magnetic field are when enough, core 104 rotates to "on" position 104B in cavity 118.

As shown in Figure 2, in "on" position 104B, the magnetic pole of core 104 with at the magnetic pole 114 of armature 112 interior formation, aim at.As shown in fig. 1, when the energy of coil 110 is removed, while removing thus the magnetic field being produced by armature 112, core 104 causes core 104 to turn back to nature 104A with housing 106 magnetic field.When energy is removed from coil 110, core 104 can rotate to turn back to nature 104A in either direction.Alternatively, core 104 can be configured to for example, in a direction of rotation (clockwise or counter clockwise direction), above rotate when coil 110 charging, then when coil 110 is uncharged, in another direction of rotation, rotates.In yet another aspect, core 104 can be configured to always to rotate in one direction (for example, when coil charges, when charging electricity, electric discharge or being discharged clockwise or counterclockwise).

In an example, housing 106 conventionally remains in position or fixes, and core 104 can change its positions with respect to the magnetic field 114 producing in armature 112.Therefore, body 102 or housing 106 can comprise for being connected to the lip-deep device of equipment.Alternatively, core 104 can be fixed, and housing is free-moving (for example, rotation).In this example, as discussed herein, core 104 is configured in response to applied magnetic field in the interior rotation of housing 106.

For example, a coil/armature can make core 104 rotations (or additionally making core 104 motion or translations) 45 degree, and another coil/armature, when energising, can make core 104 90-degree rotations.Those of skill in the art are understandable that, the angle of other motion or mobile degree or rotation can realize with respect to core 104 and the orientation of housing 106 by coil/armature.As mentioned above, core 104 can rotate according to the magnetic force applying in either direction.

In addition, embodiments of the present invention can consider that a plurality of coils and a plurality of armature are so that the specific quantity of core 104 rotation.For example, do not limit ground by the mode of example, a plurality of armatures can be arranged as by step-length (step) (30 degree step-lengths, 45 degree step-lengths etc.) and make core 104 rotations.The specific anglec of rotation can be 5 degree, 10 degree, 15 degree, 20 degree, 25 degree, 30 degree, 35 degree, 40 degree, 45 degree, 50 degree, 55 degree, 60 degree, 65 degree, 70 degree, 75 degree, 80 degree, 85 degree and 90 degree, or any angle therebetween.Embodiments of the present invention are also considered core 104 rotatablely moving and/or translational motion with respect to housing 106.

In another embodiment, can control the energy being applied on coil 110.As shown in Figures 1 and 2, armature 112 is configured to make about 90 degree of core 104 rotations.By change, be applied to the energy of coil 110, can control the rotation of core 104.Therefore, can cause core 104 to rotate to the optional position between 0 degree and approximately 90 degree.In some instances, this can allow switching device 100 in a different manner (only by the mode of example) control fluid and flow.The ability that alternatively, can change the rotation of controlling core 104 can allow switching device 100 at diverse location place, to be provided for a plurality of contacts that are electrically connected to.Therefore, can utilize and can change coil and/or the making for realizing core 104(and/or housing 106 by a plurality of armatures of switching on) rotation.

As previously mentioned, the execution mode of switching device 100 comprises a plurality of aligning utmost points 108,114.The aligning that a plurality of alignings extremely can produce calibration function (indexing function) and/or strengthen.In the situation that not having energy to be applied on coil 110, switch remains on its nature 104A, and in this nature, the poles attract of core 104 is on the respective poles in housing 106.Therefore, switch disclosed herein or switching device can make them self automatically aim in nature 104, move to and such as the "on" position of "on" position 104B and after energy is removed, they are turned back to self to their nature.Because core 104 can make himself to aim in housing 106, so it can be circular in nature, and core 104 can be around the axle rotation that essentially no friction rotation is provided.

In addition, switching device 100a can comprise controller or operationally join controller to, and described controller is controlled the energising amount (for example magnitude of current) of the coil 110 that offers one or more armature 112a.When only using an armature, the amount that is applied to the energy of coil under the control of controller can be controlled the amount of energising, and it controls the rate of change from natural magnetic state to energising magnetic field condition.The state of energising is stronger, just faster to the rate of change of energising magnetic state from natural magnetic state, and just faster to the change of the Xin position of the on-position of energising magnetic state from the physical slot of natural magnetic state thus.When the angle between physical slot and on-position can be 90 while spending, but can as described in use angle or a plurality of angle for a plurality of on-positions.

The controller of the generation of the energising of control coil and energising magnetic state can be configured to optionally timing and be convenient to make core from physical slot, to change to the duration of the energising of on-position.In some instances, controller can control coil energising so that core in the situation that do not reach the complete on-position of armature 112 completely, from physical slot, change to some arbitrarily or limit position, then controller cuts off energising so that core stops at some position such as some angle place in the situation that not moving completely or having rotated fully energized position.Then, optionally " open ", " pass " or make the energy of coil electricity can be for controlling the change of Xin position, such as changing to from physical slot arbitrarily or limiting position, such as the arbitrarily angled or predetermined angle apart from physical slot.

In one embodiment, controller can be configured to make core 104 from physical slot, to rotate to any restriction position or angle with any order.For example, core can optionally for example, rotate to 45 degree from 0 degree (, physical slot), from 30 degree to 60 degree, from 45 degree to 75 degree, then to 90 degree.Selectivity rotation can also be from 0 degree to 180 degree or even to the sequence of any angle of 360 degree.

Fig. 2 A shows the shown in broken lines switching device 100a that comprises a plurality of armature 112a.Here, each armature 112a comprises as the coil (not shown) shown in along with armature 112.Coil is identical with the coil 110 for armature 112.All coils can operationally join electrifying system or energising controller as described to, so that armature 112a can be energized and produce therein magnetic pole.As in Fig. 1 and Fig. 2, switching device 100a can comprise the first armature 112, and when the first armature 112 is switched on certain angle with respect to the magnetic pole of housing 102, the first armature has magnetic pole.For example, when the first armature 112 becomes 90 degree to be energized with the magnetic pole with housing 102, the first armature 112 can have magnetic pole.The additional armature 112a of any amount that then can comprise combination place of angle in any expectation or angle.The variation of the angle between armature can be identical or different.For example, as shown in Figure 2 A, armature 112a can be in 0 degree, 22.5 degree, 45 degree, 67.5 degree and the 90 angle places of spending, and is evenly isolated between angle.Yet angle can also be the interval in 0 degree, 35 degree, 45 degree, 60 degree and 90 degree or any other angle.In addition,, although do not illustrate particularly, armature can be arranged as from 0 degree to 180 degree or even from 1 degree to 360 or arbitrarily angled or angle intervals therebetween.In addition, can provide with identical armature different angles.For example, identical armature can be spent for 90 degree and 270, wherein can switch polarity.In any case, core 104 all rotates with the magnetic pole of the armature 112a with energising and aims at.It should be understood that each armature 112a can comprise the coil 110 and energized components part of himself, and one or more controller can be controlled energising.

Fig. 2 B-Fig. 2 D show a plurality of armatures 112 with respect to housing 102 the different layouts from core 104.Again, in order to be more prone to observe the orientation and relative rotation of armature 112, armature 112 is not to have the situation of coil to illustrate.Fig. 2 B show by housing 102 or between each armature, there is housing parts 102 different armature 112(for example, relative to each other angled as described herein).For example, armature 112 can be contained in the slit 111 in housing 102.Fig. 2 C by member 113(for example shows, and member 113 can be for combining armature 112) the separated whole armatures 112 in place, one end, member 113 makes to leave gap 115 between armature 112.Member 113 can be electrical insulator or electric conductor.Fig. 2 D shows the armature 112 and housing 102 being all attached to each other.The other end that Fig. 2 C and Fig. 2 D show housing 102 can comprise another armature 112a, and it can be armature 90 degree or main.

In an example, core 104 can be in the situation that do not touch the inwall of housing 106 and rotate.This contributes to for the desired low-power of manipulator electric switch.More particularly, utilize current manufacture method, the gap 116 between core 104 and housing 106 can be controlled to tighter tolerances (tight alignment).The nature that the character of the magnetive attraction in switching device 100 causes core 104 and rotary middle spindle for housing 106 is to directly.This feature can be used to form low-power accuracy switch or the switching device for some application.

For example, switching device shifter 100 can use in gas trap application.In this example, provide the ability of tight manufacturing tolerance can prevent that gas is from switching device 100 leakages.For example, as shown in Figure 3, if the gap 116 between core 104 and housing 106 can control to the relation of 0.0001 inch≤D2-D1≤0.0003 inch, for all gas except hydrogen, can not reveal so.In this example, D2 is the diameter of the cavity in housing 106, and D1 is the diameter of core 104.Due to the magnetic force of a plurality of balances in extremely that are present in switching device 100, therefore when core is centered in housing 106 naturally, the gap 116 around core 104 will be uniform.

In an example Zhong， gap 116 of fluid application, can be fabricated to and the relation of D2-D1 be remained be less than 0.0001 inch.0.0001 inch of lower limit is to allow maximal clearance that hydrogen is sealed.Conventionally can to all other gas, seal by gap being limited to maximum 0.0003 inch.For fluid application, can regulate the viscosity of fluid in case stopping leak reveals or slowly operation.In addition, the active-surface of switching device (for example, valve) can be processed on lyophoby ground, in case stop-pass is crossed capillarity, fluid is brought in gap 116.

Fig. 4 shows the example of the electric mechanical switch 400 of (for example gas) in fluid application by stereogram and the viewgraph of cross-section along port holes 418.Switch 400 is examples of switching device shifter 100 and comprises housing 402 and core 404.In this example, port holes 418 forms (for example, passing through center) by housing 406 and core 404.In this example, the rotating shaft that port holes 418 is orthogonal to core 404 substantially extends, but port holes 418 can be arranged in other structure and axle.

In " conventionally opening " structure of switch 400, fluid can freely flow through the valve in the situation that 404A in the raw or energy close.In other words, because core 404 is arranged as, allow fluid to flow through boring or the hole being formed in core 404, so fluid can flow through port holes 418.

In this example, when coil 410 energising, core 404 90-degree rotations are to "on" position 404B, and block fluid flow is crossed switch 400 thus.

For the common closed structure of switch 400, the utmost point of core 404 departs from 90 degree with respect to the utmost point of conventionally opening the core 404 in structure in switch 400, causes energy to be closed or closed nature.In other words, when not having energy to be applied to coil 410, the utmost point of core 404 for example can be determined switch 400(, valve with respect to the orientation of port holes 418) open or closed.

The size of port holes 418 can be according to flow or the change in flow of expectation.Can for example by forming the boring of port holes 418 or the size in hole, carry out coutroi velocity.

Fig. 5 shows can be here disclosed for controlling another example of the core 500 that the switch of fluid flow or the execution mode of switching device use.Core 500 shown in Fig. 5 can provide slowly and reveal.In this example of core 500, core 500 can comprise port 502 and port 504.Port 502 has the cross-sectional area larger than port 504.Therefore it is different, for two port holes 502 and 504 fluids, flowing.

For example, for example, when switch (, switch 400) is switched on, fluid can freely flow through port 502.When energy is removed from switch, so switch provides by the leakage slowly of port 504 and compared fluid with port holes 502, flow more limited.For comprising the multiple fluid of gaseous fluid and liquid fluid, this may be useful.Port, only by the mode of example, can have 0.1 inch of other diameter of level, and port 502 can have larger diameter.

In addition, port 502 is normally relative to each other located substantially orthogonally with port 504 in an example.In addition, between the core 500 of switch and housing coordinate or gap is constructed so that fluid can not reveal from out-of-alignment port conventionally substantially.For example, when port 504 is aimed at so that fluid is when flow, the interface between port 502 and the inwall of housing prevent extra fluid at this some place from port 502 leakages.

Fig. 6 shows the example of switch 600 in optical application.Switch 600 is examples for switching device 100.In this example, spherical lens 602(or other optical element) can be attached to core 606 Shang Zhou centers.Optical fiber 612 can be inserted in the housing 610 of the similar switch 600 of port designing with previously described valve.Make lens 602Cong position 614A rotate to position 614B the coil electricity of switch 600, stop that light moves in optical fiber 612.Magnetic force navigates to desirable pivot by core 606 naturally, has reduced significantly and has aimed at relevant manufacturing cost.As previously mentioned, lens 602 or other optical module can be arranged in core 606, so that the "on" position of coil can allow or stop light.

Fig. 7 shows the example of switch 700 in electrical applications.Switch 700 is examples for switching device 100.In electric switch application, core 702 can comprise conductor 704 or the analog of the bus type or do not have with contact 706.As mentioned above, when core 702 rotation Shi， contacts 706 engage to set up electrical connection by the wiping action with expectation or the mechanical fastener of other type.Similar with motor stator, electric switch can comprise and is designed to engage with contact 706 and the spring 708 of holding contact 706 closures.This kind of design may need higher power to carry out console switch 700.Spring design can form needs or does not need power to keep being electrically connected to.

Fig. 8 shows another example of switch 800, and it is the example of switching device 100.Switch 800 comprises housing 802 and core 814.Yet in this example, core 814 has the length that allows core 814 transverse translation in the cavity of housing 802.As shown in by magnetic field 812, magnetic field is in housing 802 Yu Xin814 ends in this example.

When coil and armature (being 804 jointly) are not switched on, core 814 is in housing 802 in the raw in 810.Because the length of the cavity with housing 802 is compared core 814 and had shorter length, therefore according to switch 800 magnetic field 812, the nature 810 of core 814 is exactly naturally placed in the middle in the cavity of housing 802.

Figure 8 illustrates the driving status 808 when coil 804 energising.Switch 800 can also be configured to enter promotion state 822.In driving status 808, the magnetic field suction core 814 being produced by coil 804 and overcome housing 802 Yu Xin814 magnetic fields and pull core 804 with coil/armature 804 ends towards switch 800.Certainly, coil/armature 804 can also be configured to produce the magnetic field that core 814 is pushed open as shown in by promotion state 822.

Switch 800 shown in Figure 8 can also have gap as above and can in fluid application, aerodynamic applications, electrical applications, optical application etc., operate.Specifically, object 816 and 818 can be contact, port, optical fiber etc. or its any combination.As described in the text, core 814 can be configured to similarly to there is optical element, contact, hole etc.One or more additional body (port, contact etc.) can be after core 814.

Although Fig. 8 illustrates core 814 between object 816 and 818, core 814 can have length (or object 816 can be orientated as with object 818), make when in the raw 810 time at least one core 814 cover.Those of skill in the art will be understood that, benefit of the present disclosure is, object 816 can be constructed so that can orientate as and cover one or more objects or contact or dock with one or more objects at any SMIS 814 of nature or "on" position with object 818.

In addition it is possible can overturning and make at least three states in the field producing by coil/armature 804.Therefore, object 816 and 818 can be opened in nature, or in object 816 and 818 one can be capped as shown by "on" position.

Fig. 9 shows an example of the switch 900 that can be three-way switch.Switch 900 is examples for switch 800.By making switch 900 energising core 814 is promoted or to be drawn to the diverse location place in the cavity of housing 802, by the switch in Fig. 9, can realize at least three kinds of states.Object 816,818 and 820 can be connected in different structures by core 814.For example, core 814 can couple together object 820 and 818, object 816 and 820 is coupled together, or do not connect any in object 816,818 and 820.
