The different capabilities battery of electronic equipment is during corresponding to the battery of different-thickness, the battery cavities of electronic equipment needs can the different different capabilities battery of compatible thickness, as shown in Figure 2 a and 2 b, the battery cavities in back cover 1 needs the battery of energy compatible thin battery 20 and 30 two kinds of different-thickness of thick battery.In addition, also need to consider the cooperation of locator card angle, two of battery fronts and structure.When structural design, the battery cavities of battery correspondence oneself can cut out certain thickness step on two angles, comes the matching battery chamber to realize the fixing of battery.In the present embodiment, in order to guarantee the compatible thickness battery of same battery cavities, the step on two orientation angles of thickness battery need to be made equally, with shape and the consistency of thickness at the Battery Card angle that guarantees the thickness battery, thereby guarantee the feasibility of assembling.
In addition, in some schemes of the present invention, due to for two kinds of batteries of thickness, two kinds of battery covers of thickness are arranged respectively, therefore, done fool-proof design on the structure of battery cover, as shown in Figure 3 a and Figure 3 b shows, diverse location at two kinds of battery covers of thickness is provided with the rib 211 and 311 that size is identical, and the relevant position on two kinds of batteries of thickness has breach.When covering battery cover, the rib 211 on thin battery lid 21 can embed the breach 201 on thin battery 20, and with the constructive interference of thick battery; Rib 311 on thick battery cover 31 can embed the breach 301 on thick battery 30, and with the constructive interference of thin battery.While having guaranteed like this to put into thin battery in the battery of mobile phone storehouse, can only cover the thin battery lid; While in the battery of mobile phone storehouse, putting into thick battery, can only cover thick battery cover.
Embodiment mono-
In the present embodiment, be to adopt eddy-current transducer (also claiming vortex type proximity switch) in conjunction with the induction part in battery, realize the detection and Identification of different capabilities battery.
Eddy effect is that electric conductor can be because electromagnetic induction produces exchange current in alternating magnetic field, and these induction currents are that the magnetic line of force around alternating magnetic field is circle and distributes, and seem just as the vortex in water, so be called vortex current.Vortex type proximity switch is also referred to as inductance approach switch, and vortex type proximity switch can produce the magnetic field of alternation, and when having conductive body to approach the switch that this can produce alternating magnetic field, electric conductor is inner can produce eddy current.This eddy current reacts to approach switch, and switch internal circuit parameter is changed, and identify thus and have or not conductive body to shift near, and then the on-off of gauge tap.Therefore, the close of object can be detected by this vortex type proximity switch, and the object that can detect must be electric conductor.
Take mobile phone terminal as example, and in the present embodiment, mobile phone disposes the battery of two kinds of different capabilities of thickness, specifically can have following two kinds of modes to realize the detection of different capabilities battery:
Further, the concrete enforcement of such scheme can have following two kinds:
The first, vortex type proximity switch is placed in the position away from battery on the electronic equipment mainboard, does not also place other metal devices near this approach switch.Simultaneously, the output terminal of approach switch is connected to interrupt pin or the universaling I/O port of primary processor.Two kinds of batteries of the thickness that electronic equipment is used are respectively to there being two kinds of battery covers.If on battery cover on corresponding mainboard the place of vortex type proximity switch place sheet metal or FPC coil, when battery cover closes, sheet metal or FPC coil be near approach switch, and the magnetic line of force produced with approach switch is perpendicular.Like this, approach switch can detect the close of electric conductor according to eddy effect, thereby makes its output signal become low level by high level.If on battery cover, electric conductor is not placed in relevant position,, when battery cover closes, the output pin of approach switch still keeps high level.It should be noted that, other electric conductors on mainboard can not produce and disturb vortex type proximity switch, because if electric conductor and magnetic line of force out of plumb are not have eddy effect.In addition, cause error detection when avoiding after mobile phone power-on being placed on other electric conductors, preferably, only in the setting-up time section after mobile phone terminal opening, carry out above-mentioned detection.In the middle of the electronic equipment start process, by judging the state of this interrupt pin or universaling I/O port, determine the capacity of battery used, enable corresponding driver.Different battery capacities can have influence on charging current and electric weight shows.
The second, be vortex type proximity switch to be placed on to the below of corresponding battery on mainboard, directly detects two kinds of batteries of thickness, on battery cover corresponding to two kinds of batteries of thickness, do not need to place electric conductor.But, need to add one deck ferrite lamina in thick battery, when so thick battery is put into battery compartment, due to the iris action of ferrite to magnetic field, approach switch is approximate can't detect the close of electric conductor (battery), and its output pin still maintains high level.And there is no ferrite lamina in thin battery, when thin battery is put into battery compartment, approach switch detects the close of electric conductor (battery) due to eddy effect, thereby makes its output signal become low level by high level.Accordingly, electronic equipment can be distinguished two kinds of batteries of thickness.
Like this, electronic equipment is corresponding to the battery of different-thickness, only needs to change corresponding battery case just passable, and the battery that battery cavities can compatible two thickness.
Embodiment 1-1
As shown in Figure 5, in the present embodiment, avoid the position of battery and place a vortex type proximity switch 12 on cell phone mainboard 2, and there is no sheet metal on thick battery cover.As shown in Figure 5, the position of covering 21 corresponding eddy current approach switchs at thin battery is mounted with a sheet metal 212.The plane of sheet metal 212 is perpendicular to the magnetic line of force of eddy current approach switch.Like this, according to eddy effect, what mobile phone can judge in start process that the active user uses is thick or the thin battery lid, and then to judge what place in battery compartment be thick or thin battery.And can carry out accordingly to determine the capacity of battery used, enable corresponding driver.Different battery capacities can adopt different charging currents and electric weight to show.
Embodiment 1-2
Take mobile phone terminal equally as example, in the present embodiment, as shown in Figure 6, eddy current approach switch 12 is placed on to the below of corresponding battery on mainboard 2, avoid the metal devices such as SD deck and SIM card seat simultaneously; And, at the inner encapsulation ferrite 310 of thick battery 30, as shown in Figure 7, do not encapsulate ferrite in thin battery.
In the present embodiment, in two kinds of battery covers of thickness, do not need to settle sheet metal, do not need to produce eddy effect according to battery cover yet.But the eddy current approach switch is placed on to the below of corresponding battery on mainboard, owing in battery, itself containing electric conductor, so, after battery is put into battery compartment, the eddy effect that the eddy current approach switch can produce according to battery, perceive putting into of battery.In order to distinguish the battery of two types, in the present embodiment, wrap into one deck ferrite in the encapsulation of thick battery, and there is no ferrite in thin battery.Because ferrite has the effect that intercepts magnetic field, therefore can almost offset the eddy effect of thick battery.Like this, after mobile phone power-on, can directly distinguish two kinds of batteries of thickness.This scheme does not need to cover battery cover can make detection according to eddy effect, relatively simpler.
Embodiment bis-
In the present embodiment, be to adopt Hall element in conjunction with the induction part in battery, realize the detection and Identification of different capabilities battery.
Hall element is a kind of magnetic field sensor of making according to Hall effect, the integrated sensor be comprised of Hall element and its accessory circuit.Hall effect is to pass to the control electric current I at the wafer two ends, and applies in the vertical direction of thin slice the uniform magnetic field that magnetic induction density is B,, on the direction perpendicular to electric current and magnetic field, will produce the Hall voltage that electric potential difference is UH.Hall element is divided into two kinds of lienar for Hall element and Hall switch sensors.The lienar for Hall element is comprised of Hall element, linear amplifier and emitter follower, and it exports analog quantity, and output voltage and externally-applied magnetic field intensity are linear.The lienar for hall device is mainly used in the measurement of some physical quantitys, such as: current measurement and displacement measurement.Hall switch sensor is by voltage stabilizer, Hall element, differential amplifier, and this schmitt trigger and output stage form, and it exports digital quantity.When additional magnetic induction density surpasses operating point, the sensor output low level, when magnetic induction density drops to operating point when following, the sensor output level is constant, and in the time of will dropping to point of release, sensor is just high level by low level transition always.Hysteresis between operating point and point of release makes switch motion more reliable.Therefore, Hall switch sensor can be used for approach switch, revolution and vehicle door status demonstration etc.
Thus, the present embodiment provides a kind of battery identification scheme of electronic equipment, specifically comprises:
In described electronic equipment, Hall element is set, and in described the first capacity battery, the magnetic induction part is set, and described the first capacity battery is when installation site, in the induction zone of described magnetic induction part in described Hall element;
When described the first capacity battery is installed in described electronic equipment, it is close that described Hall element is sensed described magnetic induction part, and output is for identifying the control signal of described the first capacity battery.
Further, described Hall element is arranged on the mainboard of described electronic equipment;
Described magnetic induction part is arranged on corresponding described Hall element place on the battery cover of described the first capacity battery.
Further, described magnetic induction part comprises magnet, and the magnetic pole of described magnet is vertical with the sensitive surface of described Hall element.
Further, the output terminal of described Hall element is connected to a processor,
When described the first capacity battery is installed in described electronic equipment, it is close that described Hall element is sensed described magnetic induction part, to this processor output low level signal; This processor is according to the described low level signal received, and identifying what install in described electronic equipment is described the first capacity battery;
And, when the second capacity battery that the magnetic induction part is not set is installed in described electronic equipment, described Hall element induction is close less than the magnetic induction part, therefore to this processor output high level signal; This processor is according to the described high level signal received, and identifying what install in described electronic equipment is described the second capacity battery.
Embodiment below in conjunction with accompanying drawing to the present embodiment is specifically described.
As shown in Figure 1, Hall element 12 is placed on the mainboard 2 of terminal device.As shown in Figure 8, the output terminal of Hall element can be connected to interrupt pin or the universaling I/O port of processor.In the middle of the electronic equipment start process, by judging the state of this interrupt pin or universaling I/O port, determine the capacity of battery used, enable corresponding driver.Wherein, different battery capacities mainly can have influence on charging current and electric weight demonstration.
As shown in Figure 9, locate to place magnet 312 above the corresponding Hall element 12 of battery cover 31 of thick battery.The magnetic pole of this magnet 312 must guarantee with the sensitive surface of hall device vertical, guarantees after battery cover 31 closes, and the changes of magnetic field that Hall element 12 can be experienced, and can cutting magnetic line.
In addition, as shown in figure 10, for avoiding interference the induction of the magnetic line of force, on mobile phone battery cover corresponding Hall element 12 above locate to establish an opening 201.
It should be noted that near this Hall element 12 the magnetic device of having tried not, and the induction zone of this Hall element 12 is vertical with the polarity of magnet 312 on battery cover 31.If magnetic pole is parallel with the sensitive surface of Hall element 12, even if after battery cover closes, the changes of magnetic field that Hall element 12 still can not be experienced, so sensor can't be exported corresponding control signal.
If battery cover is provided with magnet,, when battery cover closes, magnet is near Hall element, and Hall element is subject to changes of magnetic field, and cutting magnetic line, and the output signal of Hall element will become low level by high level.If magnet is not set on battery cover, when battery cover closes, because Hall element is not sensed changes of magnetic field, the output pin of Hall element will keep high level.Processor, according to the low and high level of Hall element output, can identify the battery of respective type.
It should be noted that, in above-described embodiment, be that battery for thick battery and two kinds of different capabilities of thin battery is that example describes, but should understand, the present invention program is not limited to the different situation of cell thickness, for example, when the battery of different capabilities has identical thickness, adopt the present invention program can identify equally.In addition, the present invention program, except mobile phone terminal, can be applied to use other any electronic equipments of rechargeable battery capable of circulation equally.
Embodiment tri-
In the present embodiment, be to adopt electro-optical pickoff in conjunction with the induction part in battery, realize the detection and Identification of different capabilities battery.
Particularly, be that different photoinduction media is set respectively on the battery of different capabilities, and in the position of the described photoinduction medium of correspondence, electro-optical pickoff be set;
When battery is installed in battery compartment, electro-optical pickoff, according to the mistiming that transmits and receives light signal, is exported corresponding control signal;
According to the different control signal of electro-optical pickoff output, the battery of identification different capabilities.
Wherein, the battery of described different capabilities can have two kinds: normal capacity battery (thin battery) and high capacity cell (thick battery);
Perhaps, more kinds of capacity can also be arranged, and by the battery cover at different capabilities/or battery body on different photoinduction media is set, so that the battery of each capacity is all different from other batteries to the reflecting properties of light signal, electro-optical pickoff can be according to the poor battery of judging different capabilities of the different time that sends and receive signal, thereby can realize identifying the purpose of different capabilities battery.
Further, described photoinduction medium can by described battery cover/or battery body on the photoinduction material form; Perhaps also can be formed by coating, the photoinduction material of paste layer on described battery cover or battery body.
Wherein, described photoinduction material comprises: monox, silicon nitride, aluminium foil, silver, copper etc.
As shown in figure 11, the output terminal of electro-optical pickoff is connected to primary processor.In the present embodiment, the position of photo-electric approach switch on corresponding mainboard on the battery cover of thick battery, can the photoinduction medium be set by the mode of coating, paste layer, perhaps to the material of relevant position battery cover and/or color, (different colours is also not quite alike for the ability of reflection ray, the reflection potential of light colour is strong, the dark colour receptivity is strong) carry out special processing, make it there is the ability to radiative diffuse reflection or mirror reflection.On the battery cover of thin battery, on corresponding mainboard, the position of photo-electric approach switch arranges the photoinduction medium that utilizing emitted light is had to absorption function, perhaps material and/or the color of relevant position battery cover are carried out to special processing, make it to utilizing emitted light, there is absorption function.
As shown in Figure 1, on the mainboard 2 of electronic equipment, electro-optical pickoff 12 is set; Simultaneously, as shown in figure 12, on battery cover 10, photoinduction medium 101 is placed in the place of corresponding electro-optical pickoff 12, and this photoinduction medium 101 can be reflecting medium or absorbing medium.
Because electro-optical pickoff is to utilize the emission light intensity of LED to produce the principle of reflection when object is close, therefore, need to make the light of LED emission can arrive on battery cover with the identification battery cover, the light reflected from battery cover also can enter the receiving position of electro-optical pickoff.
Like this, if the corresponding photo-electric proximity transducer part of battery cover can produce diffuse reflection or mirror reflection to utilizing emitted light, when battery cover closes, sensor can pass to range information of primary processor, if this distance within predetermined scope, is judged the type of this battery cover and the battery size be complementary (thick battery or thin battery); If the corresponding photo-electric proximity transducer part of battery cover can not produce diffuse reflection or mirror reflection to utilizing emitted light, when battery cover closes, sensor can pass to invalid range information of primary processor, judges the type of this battery cover and the battery size be complementary (thin battery or thick battery).
Preferably, as shown in figure 13, on the back cover of electronic equipment, the top of corresponding electro-optical pickoff 12 is provided with light inlet window 102, and the light signal that electro-optical pickoff 12 transmits and receives is by forming loop between this light inlet window 102 and photoinduction medium.
In addition, when design, must reduce as far as possible utilizing emitted light issuable diffraction in equipment, guarantee as far as possible not to be subject to the interference of other devices (components/devices that especially light signal is had the characteristic that absorbs and reflect) in the stroke of light signal; In addition, also need to consider radiative emission angle, for example, the light of launching had better not be vertical with the induction medium face, overlaps because so likely make to transmit and receive loop, and is unfavorable for that sensor receives signal.But emission angle also should not be too large, otherwise can the effect of sensor be exerted an influence.
Embodiment tetra-
In the present embodiment, be the battery that adopts capacitive transducer induction different-thickness, realize the detection and Identification of different capabilities battery.
Specifically can adopt following scheme: near the battery place, capacitive transducer is set on the mainboard of electronic equipment, capacitive transducer is connected with metering circuit; When the battery of different-thickness is installed in electronic equipment, metering circuit, according to the capacitance increase in the described capacitive transducer detected, is exported different magnitudes of voltage; Can identify the battery of the different-thickness of installing in electronic equipment according to the different magnitudes of voltage of metering circuit output.
As known, capacitive transducer is tested mechanical quantity to be converted to a kind of sensor of capacitance variations.As shown in figure 14, its ultimate principle is measured variation to be converted to the variation of sensing element electric capacity, then converts the variation of electric capacity to electric signal output through metering circuit.From the angle of energy conversion, capacitive transducer is passive transducer, is amplified and processes after surveyed mechanical quantity need to being converted to voltage or electric current.Displacement of the lines in mechanical quantity, angular displacement, interval, distance, thickness, stretching, compression, expansion, distortion etc. have the amount of close ties invariably with length; This tittle is all the amount of being measured by length or lenth ratio again, and the mutual relationship of its measuring method is also very close.In addition, there are the characteristics such as test specification is wide, highly sensitive, dynamic response fast, good stability due to capacitance type sensor, therefore, change quite slow in some mechanical quantities, and, under the minimum condition of variation range, more suitable employing capacitance type sensor is detected.
Particularly, as shown in figure 15, in the present embodiment, capacitive transducer 12 is placed in the position near battery 20 on the mainboard 2 of mobile phone terminal back cover 1, for example, capacitive transducer 12 is arranged to the thickness face facing to battery 20.After battery 20 is put into, capacitive transducer 12 can be experienced pressure and change, and the pressure that the thickness of different batteries is applied on capacitive transducer is different, and capacitive transducer can be distinguished the pressure reduction that the thin and thick battery produces fully.Therefore, can convert capacitance increase (capacitance changed) to voltage by its metering circuit.
Particularly, capacitive transducer can be arranged on to the position facing to described battery side, and the height of capacitive transducer is higher than the maximum height (being also that thin battery thickness face can not cover capacitive transducer fully) of the battery of minimum thickness, like this, when the battery of different-thickness is installed in battery cavities, the battery lateralarea that capacitive transducer is sensed can be different, thereby produce different capacitance increase.
Wherein, the design of battery cavities need be considered dodging capacitive transducer.For example, when putting into battery, just passable as long as capacitive transducer is sensed battery, and can not be interfered with by other structural member.
In addition, due to capacitance in capacitive transducer and the capacitance variations value all very small, therefore, need to detect this small capacitance increment by means of metering circuit, and convert thereof into the voltage that becomes the single-valued function relation with it.
When as shown in Figure 3, capacitive transducer is worked, the capacitance variations value is changed voltage corresponding to output by metering circuit.Like this, in battery is packed battery cavities into after, battery approaches capacitive transducer, capacitive transducer is experienced pressure and is changed, change in voltage appears in the output signal of its metering circuit.Wherein, when the battery that two kinds of thickness are only arranged, when thick battery and thin battery, due to the different-thickness thick, that thin battery has, the pressure of its generation is also by difference, and the voltage of output has dividing of height, according to the height of magnitude of voltage, can judge used battery types.A kind of simple implementation is can judge that output voltage is as high level or low level by the threshold voltage of setting, and then judge the battery of different-thickness.
Simultaneously, the output terminal of metering circuit can be connected to interrupt pin or the universaling I/O port of primary processor.In the electronic equipment start process, by judging the state of this interrupt pin or universaling I/O port, determine the capacity of battery used, enable corresponding driver, select the charging current of different battery capacities and electric weight to show.
Further, the present invention program can also realize identifying the battery of more kinds of different-thickness in electronic equipment: after the battery of different-thickness is put battery cavities into, the area of the battery side that capacitive transducer is sensed is different, for example, after small cell is put into, can block 1/3rd of capacitive transducer; After the medium size battery is put into, can block 1/2nd of capacitive transducer; After the large size battery is put into, can block 2/3rds of capacitive transducer.Due to the cell area difference that capacitive transducer is sensed, the capacitance increase of generation is also different, thereby exportable different signal value (as magnitude of voltage), according to different signal value, can identify the battery of different-thickness.
As shown in figure 17, the concrete composition of metering circuit mainly comprises: frequency-modulated generator, limiter, frequency discriminator and amplifier.Wherein, capacitive transducer is as the part of oscillator resonant tank.When input quantity causes electric capacity to change, the oscillation frequency of oscillator just changes; Frequency-modulated generator and limiter are for capacitance increase being converted to the variation of frequency, and frequency discriminator can convert the variation of frequency to the variation of amplitude, and amplifier is used for amplifying amplitude signal so that processor judgement low and high level.
