Although the purpose of magnetic cell is similar to, i.e. attach the article to electronic equipment, it will be appreciated that these mechanisms can pole The earth changes.In some cases, magnetic field can be configured differently.As an example, the magnetic surface that side is installed can provide the One magnetic force, and front magnetic surface can provide second magnetic force different from the first magnetic force.This can be partially due to different guarantor Hold and require and different surface areas, i.e. free space, and its impact on electronic equipment internal assembly.An example In son, the magnetic surface that side is installed provides the bigger retentivity securing the article to electronic equipment, i.e. it is main bed knife, And front magnetic surface is auxiliary bed knife.

In one example, fold 50 includes some, and these parts are semirigid and relative to each other bend To form removable and soft fold.In one embodiment, fold 50 can be folded into one or more difference and joins Put, and magnetic systems described above holding can be similar in such arrangements by use in some cases.Below will more Describe these and other embodiment in detail.In addition, it will be appreciated that the embodiment described is not limited to cover, and can be used it Its configuration, including such as, as the accessory device of suspension arrangement, for electronic equipment to improve the support machine of viewing display Structure, and display touch non-sensitive part for or input touch event supporting mechanism etc..

Electronic equipment and goods can be to take many forms.The remainder discussed for this, calculates with hand-portable and sets Standby description electronic equipment.Therefore, Fig. 5 shows the axonometric chart of the electronic equipment 100 according to the embodiment described.Electronic equipment 100 can process data, it is particularly possible to process the media data of such as audio frequency, video, image etc..As an example, electronic equipment 100 can correspond generally to can be as smart phone, music player, game machine, vision player, personal digital assistant (PDA), the equipment that tablet PC etc. perform.Electronic equipment 100 can also is that hand-held.For as handheld device, electronics Equipment 100 can be held in a hands, operates (i.e., it is not necessary to the datum level of such as desktop) with another hands simultaneously.Therefore, electricity Subset 100 can be held in a hands, provides operation input order with another hands simultaneously.Operation input order can include Operation volume switch, maintained switch or touch sensitive surface such as touch-sensitive display equipment or the Trackpad offer of giving input.

Electronic equipment 100 can include housing 102.In certain embodiments, housing 102 can be taked with any number of Material, such as plastics or can with casting, mould or formed the form of single-piece housing that the nonmagnetic metal of intended shape is formed.? In the case of electronic equipment 100 has metal shell and is combined with function based on radio frequency (RF), a part for housing 102 can To include through wireless material, such as pottery or plastics.Housing 102 can be configured to close multiple intraware.Such as, Housing 102 can close and support various structure and electronic building brick (including IC chip) to be electronic equipment 100 There is provided and calculate operation.Integrated circuit can be to take the form of chip, chipset or module, and any integrated circuit can be surface mounted In printed circuit board (PCB) or PCB or other supporting construction.Such as, main logic board (MLB) can have integrated electricity mounted thereto Road, these integrated circuits at least can include microprocessor, semiconductor memory (such as FLASH) and various support circuit etc.. Housing 102 can include that opening 104, opening 104 are used for placing intraware, and it is possible if desired to have receiving for Presenting the size of the display module of vision content, protective layer 106 can cover and protect this display module.In some situation Under, display module can be to touch sensitivity, thus allows stereognosis to input, and sense of touch input can be used for carrying to electronic equipment 100 For control signal.In some cases, display module can be big significantly the showing of overlay electronic equipment front major part area Show region.

Electronic equipment 100 magnetic attachment system, magnetic attachment system can be included to can be used for electronic equipment 100 magnetic be attached to The object of few other applicable configuration.In magnetic attachment system can include being distributed in housing 102 and connect in some cases Receive multiple magnetic attachment features parts of housing 102.Such as, magnetic attachment system can include being positioned at electronic equipment 100 not homonymy First magnetic attachment features part 108 and the second magnetic attachment features part 110.Specifically, the first magnetic attachment features part 108 may be located at shell Near the sidewall 102a of body 102.In second magnetic attachment features part 110 may be located at opening 104 and close to the sidewall of housing 102 102b.Include having in the embodiment of the display of the cover glass being substantially full of opening 104 at electronic equipment 100, the second magnetic Attachment features part 110 can be placed under cover glass.

First magnetic attachment features part 108 is placed at sidewall 102a and can be easy to use magnetic attachment features part 108 by electricity Subset 100 magnetic is attached to another object such as another electronic equipment or accessory device being suitable for configuration.Therefore, one is not lost As property, below the first magnetic attachment features part 108 be referred to as equipment attachment features part 108.

On the other hand, the placement of the second magnetic attachment features part 110 can be easy to use the second magnetic attachment features part 110 admittedly The many aspects of fixed another equipment being attached to electronic equipment 100 by means of equipment attachment features part 108.By this way, Overall attachment between another equipment described and electronic equipment 100 can be attached than separately through the first attachment features part 108 More firm.Therefore, and the most without loss of generality, the second attachment features part 110 is referred to below as fixing attachment features part 110.

Although being not explicitly depicted, it will be appreciated that the various magnetic attachment features parts of magnetic attachment system can be positioned in housing 102 Any suitable position.Such as, magnetic attachment features part can be positioned at the inner bottom surface of housing 102 or along the side of housing 102 102c and 102d.

As shown in Figure 6, equipment attachment features part 108 and fixing attachment features part 110 each can include one or more Magnetic cell.In one example, to may be configured to magnetic each other mutual to provide magnetic field 112 for equipment attachment features part 108 Multiple magnetic cells of (illustrate only one part).In other words, the attribute (shape, field intensity etc.) in magnetic field 112 can be based on by often The reciprocal action in the magnetic field that individual magnetic cell produces.In this way it is possible to by attribute (that is, the physics arranging each magnetic cell Layout, relative size and composition magnetic pole) the simple attribute changing magnetic field 112.Such as, each magnetic cell can have different big Little, and can be arranged along axle.By this way, the magnetic attribute of each in multiple magnetic cells can play work together With, in order to set up total attribute in magnetic field 112.

In some cases, can strengthen for equipment attachment features part 108 with another by using magnetic shunt path (not shown) The part in the magnetic field 112 of the magnetic attachment between one equipment.Magnetic shunt path can be formed by the magnetic active material of such as steel or ferrum, and And the magnetic field line that originally can deviate attachment area so that direction can be placed on be redirected to the position of attachment area at least in part Put.The redirection of magnetic field line can have the effect of the average flux density increased in attachment area.

Equipment attachment features part 108 can operate in active state and inactive state.In inactive state, magnetic flux is close Degree B₁₁₂Can be equal to or over magnetic flux density threshold value B inside housing 102 outer surface rather than outside it_threshold.Change speech It, magnetic flux density B in magnetic field 112₁₁₂Outer surface at housing 102 is less than magnetic flux density threshold value B_threshold.Magnetic flux density threshold Value B_thresholdRepresenting such flux value, under this value, magnetosensitive equipment (magnetic stripe on the such as credit card) can keep substantially Unaffected.It addition, in the exterior domain of electronic equipment 100 existence self of magnetic active material (such as steel) will not to trigger equipment attached Connect feature 108 and be changed into active state from inactive state.

As it has been described above, when equipment attachment features part 108 is not activated, the outer surface of the side 102a of housing 102 Magnetic flux density B in magnetic field 112₁₁₂Less than magnetic flux density threshold value B_threshold.More specifically, for equipment attachment features part 108, magnetic Flux density B₁₁₂(that is, B=B can be changed as the function of distance x of distance magnetic cell₁₁₂(x)).Therefore, as equipment attachment spy Levy part 112 when being in inactive, magnetic flux density B₁₁₂X () can meet equation (1).

B₁₁₂(x=x_o+t)<B_thresholdEquation (1)

Wherein t is the housing 102 thickness at the 102a of side, and

x₀It it is the distance to magnetic cell inside the 102a of side.

When equipment attachment features part 108 is in inactive, outside electronic equipment 100, any magnetic flux near zone is let out Leakage (that is, B₁₁₂(x>x_o+ t)) of a sufficiently low, thus the magnetosensitive equipment near zone unlikely affects adversely.But, should Working as attention, even if in inactive state, magnetic field 112 can have the flux value B meeting equation (1)₁₁₂(x=x_o+ t), and The magnetic field of another equipment being still high enough to and place relative to its next-door neighbour is mutual.By this way, even if meeting Formula (1), it is possible to use other the appropriately configured magnetic attachment features part in another equipment activates equipment magnetic attachment features part 108。

The attribute in magnetic field 112 can at least include field intensity, magnetic polarity etc..The attribute in magnetic field 112 can be based on being included in magnetic The synthesis in the magnetic field of each magnetic cell in attachment features part 108.Combination field can be formed in polymerization magnetic field 112.Such as, magnetic Element can be arranged by this way, thus the combination in magnetic field causes the magnetic with expectation magnetic field properties (such as field intensity) accordingly Field 112.Such as, the combination of a kind of layout of magnetic cell can cause such magnetic field 112, its have largely relative to The characteristic (such as polarity and intensity) that specific axis (such as geometrical central axis) is symmetrical.

On the other hand, magnetic cell can be arranged by this way, thus the combination in the magnetic field of magnetic cell can cause At least one has the magnetic field 112 of the attribute relative to centrage antisymmetry (anti-symmetric).Such as, centrage side On magnetic cell can be positioned as north magnetic pole and point to, and the corresponding magnetic cell on centrage opposite side can be arranged to south magnetic pole In sensing.Therefore, it can the magnetic according to being considered suitable for providing the desired any-mode being matingly engaged to adjust magnetic field 112 belong to Property.For example, it is possible to by can be with another magnetic field cooperation interaction (such as, from another magnetic attachment system) with magnetic field 112 Mode arrange magnetic cell with revise magnetic field 112 magnetic attribute.Cooperation interaction between two magnetic fields can cause two objects By with clear and definite, accurate and repeatably mode magnetic each other be attached.

The attribute in magnetic field 112 can be stable.The stable attribute being meant that magnetic field can be a long time period Interior holding is basically unchanged.Therefore, it is possible to use have the attribute of substantially constant (or approximately constant) on a long time period, Or arbitrarily changing at least one assembly is changed the magnetic cell offset accordingly to create magnetic field in another assembly The stable release of 112.Magnetic cell can by relative to other magnetic cell with fixing or the most fixing configuration physical layout.Example As, each magnetic cell can each have fixed size and the polarity relative to each other arranged with particular order, thus provides magnetic The desired attribute (shape, intensity, polarity etc.) of field 112.Therefore, according to attribute and the character of magnetic cell, the shape in magnetic field 112 Can be the most constant in the upper holding of a long period (the expection operation lifetime of such as electronic equipment 100).

But in some embodiments it is possible to changed by the magnetic or other physical attribute revising at least one magnetic cell The attribute in magnetic field 112.When at least one magnetic cell has the magnetic attribute that can revise (such as, polarity or field intensity), gained magnetic Field also can be modified.Therefore, at least one magnetic cell is characterized by having dynamic magnetic properties in certain embodiments.Dynamically It is meant that and can revise at least one magnetic attribute such as polarity.By this way, the magnetic field properties in gained magnetic field can also change. Gained magnetic field can change again the magnetic characteristic in magnetic field 112, and the magnetic characteristic in magnetic field 112 can change how magnetic attachment system makes again Object magnetic each other attachment (align, orient, between two parties etc.).Electromagnet be this can of magnetic cell of on-demand amendment magnetic attribute Example.Other example includes the malleable nonmagnetic substrate injecting magnetic-doped thing (such as magnetic iron ore).By this way, malleable base Matter can be formed to affect the physical form of the character in the magnetic field produced by magnetic-doped thing material.

Turning now to the other side of magnetic attachment system, fixing attachment features part 110 can include one or more magnetic unit Part 116.When using multiple magnetic cell, the layout of multiple magnetic cells 116 can greatly change, and can set with another Standby upper collaborative feature magnetic is mutual.In one embodiment, magnetic cell 116 associated plurality of with fixed character part 110 can At least some of of this another equipment being attached to electronic equipment 100 by means of equipment attachment features part 108 is fixed with auxiliary.

At least some in multiple magnetic cells 116 can have fixed size and polarity (along the row of simple bar magnet), And some other magnetic cell in multiple magnetic cell 116 can have the magnetic attribute (such as electromagnet) that can change, the most another Some magnetic cells can have the shape providing specific magnetic characteristic.Such as, at least one in multiple magnetic cells 116 can be positioned For and be configured to (the need to) mutual with the magnetic response circuit being included in another equipment described.Therefore, magnetic response electricity Road can respond the existence (or not existing) of the specific magnetic element (multiple) of fixed character part 110.Sense with Hall effect above Device 118 describes the example of magnetic response circuit.

It should be noted that, should not extend far with the magnetic field of magnetic cell 116 generation, thus adversely affect electronic equipment Magnetosensitive circuit (such as Hall effect transducer 118) in 100.Because owing at least some of magnetic field must be prolonged in z-direction Stretch so that mutual with the magnetic active part of miscellaneous equipment, so magnetic field, in general is not contained in housing 102, this particular importance. Therefore, it is necessary to limit magnetic field in the { extension in x, y}, in order to avoid magnetosensitive circuit, such as Hall effect transducer 118 and compass 120。

In a particular embodiment, the magnetic cell of equipment attachment features part 108 is grouped into different magnetic regions.With this Mode, the magnetic field of these magnetic regions can be with superposition, in order to form magnetic field 112.Magnetic regions can include various magnetic cell, it Can be disposed in the group represented with magnetic cell 126 and 128.By magnetic cell being grouped into different magnetic regions, permissible Greatly strengthen magnetic attachment system and the ability in the magnetic field with desired characteristic is provided.Magnetic cell 126 and 128 can interactively with each other with Just magnetic field 112 is formed.In one embodiment, the group of the magnetic attribute of each in magnetic cell 126 and 128 can be taked alternately The form closed.In some cases, the layout of magnetic cell 126 and 128 can be the most relevant, in order to provides and has expectation attribute Magnetic field 112.Such as, magnetic cell 126 and 128 can be arranged so as to relative to each other, thus magnetic field 112 is relative to magnetic attachment features part The horizontal center line antisymmetry (or symmetrical) of 108.In another embodiment, magnetic field 112 can be relative to attachment features part 108 Vertical center line antisymmetry (or symmetrical).In another embodiment, magnetic field 112 can be in both the horizontal and vertical directions Antisymmetry (or symmetrical).

Fig. 7 A shows the electronic equipment 100 close to the object 200 with magnetic attachment features part 202.The magnetic of object 200 is attached Connect feature 202 can include magnetic cell, described magnetic cell each produce can interactively with each other in case flock together formation institute Obtain the independent magnetic field in magnetic field.Gained magnetic field can have can be mutual with the magnetic field 112 of electronic equipment 100, in order to clear and definite, Accurately and repeatably electronic equipment 100 and object 200 are attached together, without machanical fastener the most not by mode Need the magnetic characteristic (such as, field intensity and shape) of external auxiliary.It should be noted that, magnetic field 208 can be about 2500 Gausses, and work as When equipment attachment features part 108 is in inactive, magnetic field 112 can be about 1400 Gausses.

Object 200 can be to take many forms, including adnexa, peripheral hardware, electronic equipment etc..In one embodiment, object 200 can be to take the form of the electronic equipment of the circuit along electronic equipment 100.Therefore, electronic equipment 100 and object 200 can To use equipment attachment features part 108 and the attachment of magnetic attachment features part 202 magnetic each other, in order to form coelectron system.This association Can be the electronic component in electronic equipment 100 and the corresponding electronic element coordination with one another in object 200 with electronic system, in order to Perform the system of the function that any one electronic equipment all can not individually perform.In one embodiment, can be at electronic equipment Information is transmitted between 100 and 200.

More specifically, magnetic attachment features part 202 can at least include magnetic cell 204 and 206, each of which can produce magnetic , coordination with one another is to provide the magnetic field in magnetic field 208 (illustrate only the part in magnetic field 208).The attribute in magnetic field 208 can be with base Each in multiple magnetic cells 204 and 206 mutual.By this way, magnetic field 208 can have based on multiple magnetic cells The physical layout of each, relative size and the attribute of composition magnetic polarity in 204 and 206.Such as, magnetic cell 204 and 206 can To arrange along center line, and there is superposition to provide the magnetic attribute in the magnetic field 208 with expectation attribute.The magnetic of object 200 Magnetic flux density B of field 208₂₀₈(that is, B=B can be changed as the function of distance x of distance magnetic cell 204 and 206₂₀₈(x))。

When object 200 takes the form of the such as electronic equipment of electronic equipment 100, magnetic flux density B₂₀₈Meet equation (1).But, when object 200 takes the form of accessory device, the magnetic flux being different from the electronic equipment 100 meeting equation (1) is close Degree B₁₁₂, magnetic flux density B of accessory device 200₂₀₈Equation (2) can be met.

B₂₀₈(x=x₁+s)>B_thresholdEquation (2)

Wherein s is the housing 212 thickness at the 212a of side, and

x₁It it is internal spacing distance.

By this way, accessory device 200 can be mutual with electronic equipment 100 magnetic, and also may exit off electronic equipment 100, otherwise this is impossible.Therefore, accessory device 200 can be placed close to object 200 but need not be against electronic equipment 100 So that electronic equipment 100 and object 200 are with clear and definite, accurate and repeatably mode magnetic each other attachment.

In addition to magnetic attachment features part 202, accessory device 200 can also include can be used for and fix attachment features part 110 mutual magnetic attachment features parts 216.Magnetic attachment features part 216 can include various magnetic driving component.Some magnetic cell is permissible Take to be arranged as the form of the magnetic cell to the corresponding magnetic cell cooperation interaction fixed in attachment features part 110.Other magnetic cell Substantially can be more passive, i.e. the machine of the magnetic circuit of magnetic active member that they provide and have fixed in attachment features part 110 System.The example of magnetic passive device is ferromagnetic material, such as ferrum or steel, and it can be with the magnetic cell actively providing the magnetic field being associated Alternately.By this way, ferromagnetic material can be mutual with magnetic field, in order to completes the passive device in attachment features part 216 with solid Determine the magnetic circuit between the active member in attachment features part 110.

Fig. 7 B shows to can be used for providing and supports function and the accessory device 200 for electronic equipment 100 service.By permitting Permitted that there is magnetic flux density B meeting equation (2)₂₀₈The part in magnetic field 208 extend to, in region 214, equipment to be created attached Meet the magnetic attraction F between feature 108 and adnexa attachment features part 202_net, wherein clean magnetic attraction F_netMeet equation (3a) With equation (3b).

F_net=(L_total)·B²/μ₀Equation (3a)

B/B₀=f (x_sep) equation (3b)

Wherein L_totalIt it is the total surface area of magnetic cell

B is total magnetic flux density (B₂₀₈+B₁₁₂)

X_sepIt is the spacing distance between magnetic cell,

B₀It it is the magnetic flux density of magnetic regions surface.

Clean magnetic attraction F_netIt is that attachment features part 202 can be used for swashing owing to magnetic field 208 and the mutual of magnetic field 112 produce Equipment attachment features part 108 alive.It addition, when equipment attachment features part 108 is activated, magnetic flux density B₁₁₂Now at moving type State meets equation (4).

B₁₁₂(x=x_o+t)>B_threshold,Equation (4)

Magnetic flux density B in region 214₁₁₂This increase can cause between accessory device 200 and electronic equipment 100 Clean magnetic attraction F_netDramatically increase.Further, since clean magnetic attraction F_netAlong with total magnetic flux density B (B₂₀₈+B₁₁₂) change, And magnetic flux density B typically can change (that is, equation 3 (b)) on the contrary along with spacing distance, when electronic equipment 100 and adnexa set Closer to each other for 200, and spacing distance X_sepDrop to what the physical contact with electronic equipment 100 and accessory device 200 was consistent During limits value, clean magnetic attraction F_netIncrease can sharply increase in relatively short time quantum.This clean magnetic attraction F_net Sharply increase equipment can be caused to be pulled together rapidly, as seen in figure 7 c, this is referred to alternatively as " adhesive is in place ", and Fig. 7 C illustrates Cooperative system 300 along composition surface 218 with electronic equipment 100 form of accessory device 200 magnetic attachment.It should be noted that, In a representational embodiment, the magnetic cell in equipment attachment features part 108 can be N52 type magnet, and attachment features Magnetic cell in part 216 can be N53 type magnet.It addition, clean magnetic attraction can be about 10 newton at least 20 newton, its Middle activation equipment attachment features part 108 may need about 3 newton.

The all clean magnetic attraction F of the magnetic cell that can couple according to all actives_netiSummation draw equipment 100 and set Total clean magnetic attraction F at composition surface 218 between standby 200_NET.In other words, total clean magnetic attraction F_NETMeet equation (5).

Wherein F_netiIt it is the clean magnetic attraction of each assembly in n assembly.In one embodiment, clean magnetic attraction F_netiIt is generally perpendicular to the part that composition surface 218 intersects with magnetic field 112 and magnetic field 208.

In order to ensure total magnetic attachment forces F_NETIt is uniform along the composition surface between equipment 100 and equipment 200, attachment The spacing distance between each corresponding magnetic cell in feature 108 and 202 is well controlled.Can be by such as making magnetic Element has and meets the shape of device shaped and carry out control interval distance well.Such as, if equipment 100 has batten (bending) The housing of shape, so that the magnetic cell in equipment 100 has the shape meeting this curved shape.It addition, magnetic cell can quilt Formed by this way, so that the magnetic vector of corresponding magnetic cell is in alignment with each other.In this way it is possible to desirably control Make the size and Orientation of clean magnetic attraction.

One result of alignment magnetic vector is can to control the direction of the clean magnetic force between each magnetic cell well.Separately Outward, by the spacing distance between corresponding magnetic cell is reduced to minimum, the clean magnetic between each magnetic cell can be maximized Gravitation F_neti.It addition, by keeping the spacing distance of general uniform between each magnetic cell, can carry along composition surface 218 For corresponding uniform magnetic attachment forces.It addition, by suitably adjusting corresponding magnetic vector, composition surface can be orthogonal to and applies F_net。

In addition to minimizing the spacing distance between corresponding magnetic cell, it is also possible to use magnetic shunt path to increase corresponding magnetic unit Magnetic flux density between part.The magnetic shunt path formed by magnetic active material such as ferrum or steel can be placed on magnetic cell or attached Closely, it is achieved magnetic flux line is directed to the effect of desired orientation.By this way, such as, this can deviate the propagation of corresponding magnetic cell Magnetic flux line can be partly redirected to desired direction, such as towards the magnetic attachment area between equipment, thus increases total magnetic Flux density.Therefore, the obtainable magnetic flux density increased between magnetic cell can cause dramatically increasing of clean magnetic attraction.

Fig. 8 A shows the embodiment of attachment features part 110.Specifically, attachment features part 110 can be the one of housing 102 Part.Specifically, attachment features part can include the magnetic cell 402 that may be mounted to that on the ledge 404 of housing 102.Magnetic Element 402 can greatly change.Such as, magnetic cell 402 can by space be arranged as on ledge 404 for setting at adnexa Standby at least some of place is attached and is fixed to the array of the particular aspects of electronic equipment 100.Such as, take when accessory device During fold form, it is possible to use magnetic cell 402 by magnetically fixed for fold to electronic equipment 100, in order to cover display at least one Part.The size and shape of array can also greatly change.In the embodiment shown in Fig. 8 A, array is rectangle and has Size including the signal portion of ledge 404.

Fig. 8 B shows the multiple magnetic cells can being attached in accessory device by the part as attachment features part 216 410.Some in multiple magnetic cells 410 but the not all magnetic cell 402 that can correspond to, and be used for adnexa 200 magnetic It is attached to electronic equipment 100.In another embodiment, in multiple magnetic cells 410, all or most of magnetic cell can be used for The some of accessory device 200 is fixed together, in order to form other support knot that can use in conjunction with electronic equipment 100 Structure.In one embodiment, magnetic cell 414 can be used for activating magnetosensitive circuit, such as Hall effect transducer 118.

Fig. 9 A-9C shows the representative magnetic attachment features part 500 according to the embodiment described.Magnetic attachment features part 500 Can such as correspond to the equipment attachment features part 108 shown in Fig. 6 and Fig. 7 A-7C.At inactive state, magnetic attachment features part Magnetic cell in 500 can be positioned remote from housing 102, in order to minimizes the magnetic field line propagated by housing 102.The opposing party Face, in active state, magnetic cell can move towards housing 102, in order to increases the number of the magnetic field line propagated by housing 102 Mesh, thus meet equation (2).

The mode that magnetic cell moves can greatly change.Such as, magnetic cell can rotate, rotate, translate, slip etc.. In one example, magnetic cell can be positioned in and allow magnetic cell to slide into accordingly from the primary importance corresponding to inactive state In the passage of the second position of active state.

In the specific embodiment shown in Fig. 9 A-9C, attachment features part 500 can include having can be a time period The magnetic cell 502 of the magnetic attribute that upper holding is stable.For example, it may be desired to magnetic attachment attribute operates in the expection of electronic equipment 100 Keep stable during life-span.By this way, the magnetic field of each magnet the magnetic field formed alternately is also stable by holding.Magnetic field Stability can cause extremely reproducible attachment to process.When electronic equipment 100 and other appropriately configured object (all if desired for Consistent pinpoint accessory device 200) experience repeatedly and repeat attachment circulation (attachment/separately) time, this weigh Renaturation is useful especially.

In shown representative embodiment, magnetic cell 502 can be to take many forms.Such as, magnetic cell 502 can be adopted Take with particular order and the shape of multiple magnets with stable magnetic attribute (such as polarity and intrinsic magnetic intensity) of deployment arrangements Formula.But, in order to meet equation (1) when magnetic attachment features part 500 is in inactive, outside magnetic cell 502 must be with housing 102 At least keep at a distance x=(x in portion₀+t).In other words, in order to meet equation (1), the size of equipment attachment features part 500 must be extremely Consider magnetic attribute and the physical layout of magnetic cell 502 less.

Therefore, magnetic cell 502 can be attached to be arranged as playing retentivity F_retainMaintaining body 504.Retentivity F_retainCan be used for magnetic cell 502 is maintained at the interior position of equipment attachment features part 500, thus as equipment attachment spy Levy and cause when part 500 is in inactive that there is outside electronic equipment 100 little or no flux leakage and (that is, meet equation (1)).In one embodiment, maintaining body 504 can be taked to be arranged as providing retentivity F according to equation (6)_retainSpring Form:

F_retain=k △ x equation (6)

Wherein k is to maintain the spring constant of mechanism 504, and

Δ x is the displacement from equilbrium position.

Such as, Fig. 9 B shows the representative magnetic attachment features part 500 of active state.By appropriately configured magnetic cell 502 With the magnetic cell in adnexa attachment features part 204, the magnetic field that the magnetic field of magnetic cell 502 and adnexa attachment features part 204 produce Gained magnetic can create at least big as needed for activation magnetic attachment features part 500 clean magnetic attraction alternately.In other words, clean magnetic Captivation can at least have the activating force F meeting equation (7)_actQuantity, thus overcome retentivity F_retainSo that magnetic is first Part 502 just moves to moving position (that is, x=x from passive position (that is, x=0)₀)。

F_act≥F_retain(Δ x=x_o) equation (7)

But, another magnetic only producing the magnetic field with the attribute " mated " with the magnetic field properties of magnetic cell 502 is attached Connect feature and can activate magnetic attachment features part 500.Therefore, as shown in Figure 9 C, be positioned at housing 102 outer surface with magnetic actively Existence (that is, the x=x of the object 506 that material (such as steel) is formed₀+ t) magnetic attachment features part 500 can not be activated.More specifically, In one embodiment, the clean magnetic attraction produced between object 506 and magnetic attachment features part 500 is less than 2NT, and activating force F_ACT3NT can be about.

More specifically, in order to be changed into active state from inactive state, produce between magnetic cell 502 and object 506 Magnetic force have to be larger than activating force F_ACT.But, the magnetic flux in the magnetic field owing to producing with magnetic cell 502 in housing 102 outer surface Density is less than B_threshold, any magnetic force produced between object 506 and magnetic cell 502 is significantly less than F_retain, and therefore It is unsatisfactory for equation (7).Therefore, magnetic cell 502 is maintained at the position of about x=0, and magnetic attachment features part 500 can not experience Transformation from inactive state to active state.

Should be appreciated that spring can greatly change.Such as, it can change according to mobile type.Example include tension, Compress, reverse, upset etc..In a kind of specific implementation, use leaf spring.

Shall also be noted that in certain embodiments, magnetic cell 502 can be fixed in the way of need not spring.At these Embodiment, although equation (1) may be unsatisfactory for, but it can be a kind of actual arrangement.

Figure 10 shows the embodiment of equipment attachment features part 600 according to an embodiment of the invention.Attachment features Part 600 can correspond to the element 208 in Fig. 6 and Fig. 7 A-7C.Except replacing single mechanism, use multiple mechanism and more Body ground uses outside a pair mechanism of magnetic cell 602 and magnetic cell 604 form, and this embodiment is similar to the reality shown in Fig. 9 A-9C Execute example.Specifically, Figure 10 shows the equipment attachment features part 600 of active state.More specifically, be attached to magnetic cell 602 Spring 606 and the respective extended distance Δ x of spring 608 being attached to magnetic cell 604.

In this system, the two mechanisms combine is to form magnetic field.They can be individually moved, or they can be connected It is connected together to move as a unit.Spring force and magnetic force can change.Such as, system can be symmetrical or the most right Claim.The layout of magnetic cell can be similar or different.It is equally symmetrical or asymmetric.This configuration can take Certainly in the needs of system.

Magnetic attachment system can be to take many forms, and every kind of form provides the object that can be used for multiple applicable configurations attached Repeatable and the accurate magnetic attachment means being connected together.

Figure 11 A-11B shows according to an embodiment, the equipment attachment features part of equipment attachment features part 700 form The specific implementation of 108.Equipment attachment features part can correspond to the element 108 shown in Fig. 6 and Fig. 7 A-7C.In some cases, Equipment attachment features part 700 can be used in conjunction with the spring 606 and 608 shown in Figure 10.As shown in Figure 11 A, equipment attachment features Part 700.Specifically, equipment attachment features part 700 is shown in inactive state and has the magnetic group can being closed in the enclosure The magnetic cell of part 702 form.By this way, the maintaining body (not shown) being attached to magnetic assembly 702 can play relevant guarantor Holding force F_retain.Retentivity F_retainCan be used for being maintained at magnetic assembly 702 and be in inactive shape with equipment attachment features part 700 The position that state (that is, meeting equation (1)) is consistent.

Each magnetic assembly 702 can include independent magnet.In the described embodiment, independent magnet can be disposed in magnet pole Property be oriented formed coding magnetic structure structure in.Coding magnetic structure can be by a series of magnetic poles and magnetic strength in some cases Degree is formed.In other words, magnetic pole sequence may be expressed as such as+1 ,+1 ,-1 ,+1 ,-1 ,+1 ,-1 ,-1}.For this particular case Son, the direction of "+1 " instruction magnet and intensity.Therefore, positive sign "+" may indicate that corresponding magnet is aligned and has specific direction Magnetic vector, negative sign "-" may indicate that rightabout magnetic vector, and the intensity of one unit magnet of " 1 " instruction.

When multiple magnets of identical polar are placed one by one, can combine in multiple magnet each Magnetic field, thus multiple magnet can be deemed to be equivalent to single magnet, this single magnet has the composite attribute of the plurality of magnet. Such as, {+1 ,+1 ,-1 ,+1 ,-1 ,+1 ,-1 ,-1} can be deemed to be equivalent to embody the coding magnetic order row of 8 independent magnets of expression Be 6 independent magnet arrays coding magnetic order row+2 ,-1 ,+1 ,-1 ,+1 ,-2}.In one embodiment, first and last position The magnet put can have the magnetic intensity identical with other magnet in array, but it is correspondingly sized to double it.The opposing party Face, first and the magnet of rearmost position can have about the same size with other magnet, but have and double other magnetic The magnetic intensity of body.In any case, the identity property of magnetic attribute can provide greater compactness of coding magnetic order to arrange.Less size can Contribute to reducing weight, and keep accommodating the valuable inner space quantity needed for magnetic attachment features part.Further, since magnetic Flux density is directly relevant by its area propagated with magnetic field line, when given magnetic flux is reduced by its area propagated, and gained Magnetic flux density increase.

In one embodiment, magnetic assembly 702 can include the independent magnet being respectively provided with relative size 2L, 1L and 1L 712a, 712b and 712c, wherein " L " representation unit length.Should be appreciated that as discussed above, there is relative size " 2L " Magnet can be embodied in have the single magnet of " 2L " physical length, two be close to each there is length " 1L " and have The magnet of the magnetic pole being in alignment with each other, there is the magnet of unit length L of the magnetic intensity doubling other magnet.Therefore, for this The remainder discussed, for term 2L and 1L, " L " can be with representation unit length, and the relative intensity of magnet can be by with phase The numeral expression of association.Such as, there is the magnet of relative magnetic intensity " 1 " and length " 2L " and can be deemed to be equivalent to have relatively strong Degree " 2 " and the magnet of length " 1L ".In this way it is possible to use relative magnetic intensity and both formation coding magnetic structures of orientation.

Such as, magnet 712a can have the total length being approximately twice magnet 712b or 712c.On the other hand, magnet 712a can have equal length with magnet 712b or 712c, but has the intrinsic magnetic strength doubling magnet 712b or 712c Degree.In another embodiment, magnet 712a can be formed what magnet was formed by two (or more) that corresponding polarity is alignd Equivalent magnet.

In one embodiment, each magnet 712a, b, c can be spaced in a predetermined distance from each other.Such as, realize in one In, magnet can be equally spaced from each other.Certainly, this interval is expectation magnetic attribute forecast based on the magnetic field produced.At another In individual embodiment, have and oppose that the magnet of neat polarity can be attached by magnetic each other.In this way it is possible to use adjacent magnets it Between the magnetic knot that formed close the integrity of the magnet sequence kept in magnetic assembly.However, it is necessary to by externally applied force will have right The magnet of neat polarity keeps together, in order to overcome the repulsion magnetic force produced between two alignment magnets.

In addition to size and location, can the magnetic expecting Attributions selection magnet 712a, b, c based on the magnetic field produced Pole.But, in the illustrated embodiment, the most end-to-end magnetic of magnetic cell couples, thus reduces requisite space amount, and by subtracting The overall area that little magnetic field line is propagated wherein increases magnetic flux density.

Specifically, magnetic assembly 702 can have particular magnetic polarity pattern and arrange, wherein each quilt in magnet 712a, b, c Orient in the way of itself N or S magnetic pole aligns (or opposing neat) in a specific way.Such as, the magnet in magnetic assembly 702 can be arranged For formed first coding magnetic structure+1 ,-1 ,+1}, wherein the magnetic pole of magnet 712a, b, c by according to the first magnetic polarity pattern P1, P2, P1} align, it means that the magnetic pole of the magnet 712a magnetic pole relative to magnet 712b is opposed neat, the magnetic pole phase of magnet 712b Magnetic pole for magnet 712c is opposed neat.

Magnetic assembly 702 can also include independent magnet 714a, b, c, and is respectively provided with relative size 1L, 1L and 2L.Separately Outward, magnet 714a, b, c can be arranged to basis and the first magnetic polarity pattern { second magnetic pole of P1, P2, P1} contrary (or complementary) { P2, P1, P2}'s sexual norm align its respective poles.According to coding magnetic structure, magnet 714a, b, c can encode according to first Magnetic structure+1 ,-1 ,+1} contrary or complementary second coding magnetic order row-1, and+1 ,-1} align.Magnet 712a, b, c and magnet Antisymmetric relation between 714a, b, c provides relative to the antisymmetric magnetic field of centrage 716.

Figure 11 A and 11B also show the specific implementation of adnexa attachment features part 800, and adnexa attachment features part 800 can be with example As corresponding to the element 202 shown in Fig. 6 and Fig. 7 A-7C.Magnetic assembly 802 can include multiple magnetic cell.Magnetic cell can be by with group Close the mode mated in magnetic field with the magnetic field of magnetic assembly 702 to arrange.

Magnetic assembly 802 can include magnet 802a, 802b and 802c, each of which have with in magnetic assembly 702 The about the same size of corresponding magnet 712a, 712b and 712c.But, in order to maximize clean magnetic attraction F_netAnd by magnetic Magnetic between Chang is driven into expectation balance point alternately, and magnet 802a, b, c are by based on the second magnetic polarity pattern { P2, P1, P2} couple Together.Magnetic assembly 802 can also include 804a, 804b and 804c, and each of which has big with corresponding magnet 714a, 714b and 714c The most identical size.In addition to consistent with the overall goal that the magnetic between magnetic field balances alternately at expectation equipment configuration, magnetic Body 804a, b, c are by according to the first magnetic polarity pattern, { P1, P2, P1} align.

Figure 11 B show due to magnetic assembly 702 and 802 between the equipment attachment features part that is active alternately of magnetic 700.Specifically, " mate ", then due to the layout of the magnetic cell between attachment features part 700 and adnexa attachment features part 800 Magnetic between magnetic field is mutual so that magnetic assembly 702 moves to active state (that is, x=from inactive state (that is, x=0) x₀)。

Figure 12 shows a series of relative movement positions of the magnetic structure of magnetic assembly 702 and the complementary magnetic structure of magnetic assembly 802 Put.Magnetic assembly 702 is shown as by with coding magnetic order row, {+2 ,-1 ,+1 ,-1 ,+1 ,-2} encode.Magnetic assembly 802 be shown as by With complementary encoding magnetic order row, {-2 ,+1 ,-1 ,+1 ,-1 ,+2} encode.For this example, magnet can have identical or substantially phase Same magnetic field intensity (or amplitude), for the purpose of this example, it provides with unit 1, and (wherein A=attracts, and R=repels, A =-R, A=1, R=-1).In this example, magnetic assembly 702 and 802 is moved relative to " 1L " length (note every time Meaning, the antisymmetry about centrage 716 of coding magnetic order row allows the result being moved to the left to be the mirror image of the result moved right, Therefore, illustrate only move right).

For each relevant permutation, calculate the number number plus attraction magnet of repulsive magnets, the most each arrangement tool Making a concerted effort of with good grounds magnetic force function based on magnets magnetic fields intensity.In other words, can be according to this structure from left to right at each magnetic Position in relative magnetic structure directly relative to corresponding magnet mutual each magnet or each power of magnet pair Summation, determines the total magnetic force between the first and second magnetic structures.In the case of only existing a magnet, corresponding magnet is 0, and And power is 0.Exist in the case of two magnets, for each unit magnet, for doing one's utmost as R, and for contrast pole Power is A.

Can be that each figure calculates total magnetic force, and subsidiary relative movement value is each to illustrate total magnetic force.Therefore, use {+2 ,-1 ,+1 ,-1 ,+1 ,-2} can cause the clean magnetic changing into+8 (that is ,+8A) from-3 (that is, 3R) to specific coding magnetic order row Gravitation F_net, wherein align when magnetic assembly 702 and 802, thus when its corresponding encoded is also alignd, peak value occur.It should be noted that, non-peak It is worth clean magnetic attraction to change to+4 from-3.Thus, clean magnetic force so that magnetic assembly 702 typically repels each other, unless it Be aligned thus their each magnet relevant to complimentary magnet (that is, align with the arctic of another magnet in the South Pole of magnet Or vice versa as the same).In other words, when magnetic assembly 702 and 802 alignment thus during the most substantially mirror image, magnetic assembly 702 and 802 height Relevant.

Shall also be noted that and (that is, be similar to push up end mismatch, also referred to as when magnetic assembly 702 and 802 phase 180 ° Reverse), the clean magnetic force of generation can be about 8R.Therefore, the equipment pole using the attachment of magnetic assembly 702 and 802 magnetic each other can not Can reverse attachment.

As shown in figure 13, when magnetic assembly 702 with 802 corresponding to the position of centrage 716 relevant time, function F_NET(L) There is global maximum.In other words, when all magnetic cells in magnetic assembly 702 and 802 have opposite polarity alignment each other, letter Number F_NET(L=0) reach maximum (that is, 8A).Arbitrarily other configuration (that is, F_NET(L ≠ 0)) cause clean magnetic force F_NETLess than overall situation pole Big value (8A).But shall also be noted that function F_NET(L) have and allow at least two of weak attachment between magnetic assembly 702 and 802 Individual local maximum (that is, F_NET(L=± 3)).But, only when the equipment magnetic attachment features part 700 being associated with magnetic assembly 702 When correctly being activated, strong lasting attachment just can occur.Therefore, the activating force F of equation (8) is met by foundation_ACT, can To avoid the weak attachment between " pseudo-activate " or the magnetic assembly 702 and 802 of equipment magnetic attachment features part 700.

F_NET(L=local maximum)≤F_ACT≤F_NET(the L=overall situation is greatly) equation (8) shall also be noted that activating force F_ACTLogical Cross equation (6) and retentivity F_retainRelevant.By this way, equation (6) and according to function F_NET(L) equation (8) can by with In the fit value determining spring constant k.

Figure 14 and 15 shows the other embodiments that magnetic cell can vertically and horizontally be arranged.It addition, magnetic cell can have There is such size, thus there is the polarity extended in both the horizontal and vertical directions.Such as, arrange that 1000 show two row Magnetic cell, the most each magnetic cell extended height H in vertical direction.In the layout illustrated, each vertically arranged magnetic unit Part has same magnetic polarity, forms equivalent magnetic structure 1002.In other words, arrange 1000 and arrange that 1002 are both characterized by Have coding magnetic order row+2 ,-2 ,+2 ,-2 ,+2 ,-2}.

Figure 15 shows according to the embodiment described, and is configured to the top view of the magnetic array of two-dimensional encoded magnetic order row 1004. Two-dimensional encoded magnetic order row 1004 can be used for extending on the region of extension combination field in x and y both direction.This extension area Territory can cause the increase that can be used for propagating the region of magnetic field line, and this can cause magnetic flux to increase and the increasing that matches of clean magnetic attraction Add.In addition to providing the magnetic attachment improved, two-dimensional encoded magnetic order row 1004 can non-whole with approximate magnetic attribute such as magnetic intensity Numerical value.Such as, use magnetic arrange 1004, the magnetic field of various assembly can be combined so as Approximation Coding magnetic order row+1.5 ,-1.5 ,+ 1.5,-1.5,+1.5,-1.5}.It addition, in addition to horizontal alignment arranges, two-dimensional encoded magnetic order row 1004 can assist offer Vertical alignment arranges.
