In one embodiment, described control circuit 120 can also include：Microcontroller 125, is couple to each contact and opens Close the 4th end of element, in response to described first charging contact set and described second charging contact set is detected, controlling Make the contact switch element electrically connecting with each charging contact in described first charging contact set, so that described contact is opened Close element corresponding charging contact is couple to described first voltage, and control with described second charging contact set in The electrical connection of each charging contact contact switch element so that described contact switch element is by corresponding charging contact It is couple to described second voltage.So, microcontroller 125 can be electrically charged end equipment 200 to be linked into charging end equipment 100 It is charged operating, this be electrically charged end equipment 200 two is electrically charged two chargings respectively with this charging end equipment 100 for the contact Contact set electrical contact.

In order to avoid unnecessarily expending charge power, eliminating the potentially possible of short circuit, this microcontroller 125 can also be controlled Make the contact electrically connecting with each charging contact outside described first charging contact set and described second charging contact set Switch element, so that described contact switch element will be floating for corresponding charging contact.

More generally, microcontroller 125 can be used for producing the control logic for contact switch element 121, for leading to Cross the break-make controlling contact switch element 121, to have detected whether that equipment accesses charging end equipment 100, to have judged that access device is No is to be electrically charged end equipment 200, will be electrically charged end equipment 200 and be connected to charge power supply to be charged operating, and charge When completing or when being electrically charged end equipment 200 and being removed, cut off charge power supply.For this reason, microcontroller 125 can be by microcomputer The integrated one-chip microcomputer on a single die of major part of calculation machine.Specifically, it can be 51 single-chip microcomputers, be based on The microcontroller of 8 Atmel AT MEGA328P, STM8 of STC etc..

As described above, to be electrically charged end equipment 200 be charged operation before, microcontroller 125 is firstly the need of detection Whether charging end equipment 100 there is equipment access, and judge whether access device is to be electrically charged end equipment 200.

For this reason, as shown in Fig. 2 in one embodiment, described control circuit 120 can also include：Equipment recognition component 122, described equipment recognition component 122 is resistance element, and its first end is couple to the 3rd end of each contact switch element 121, Second end is couple to described second voltage.

For example, this equipment recognition component 122 can be the larger resistance of a resistance, and sets to realize being electrically charged end Standby 200 detection, the resistance of this equipment recognition component 122 can close to (or preferably, equal to) be coupled in described in be electrically charged The first of end equipment 200 is electrically charged contact and the second equipment being electrically charged between contact is identified the resistance of element.For example, this sets The resistance of standby recognition component 122 can be 22 kilo-ohms (k Ω).

Magnitude of voltage in response to detecting at the first end of described equipment recognition component is the first numerical value, described microcontroller Determine that the charging contact being couple to described first voltage is not same with the charging contact being couple to other contact switch elements described When with described be electrically charged the first of end equipment be electrically charged contact and described second be electrically charged one of contact electrical contact, also do not distinguish It is electrically charged contact and described second with described first and be electrically charged contact electrical contact；In response to described equipment recognition component is detected Magnitude of voltage at first end is second value, and described microcontroller determines the charging contact being couple to described first voltage and couples Charging contact to other contact switch elements described is electrically charged contact and described second respectively and is electrically charged contact with described first Electrical contact；Magnitude of voltage in response to detecting at the first end of described equipment recognition component is third value, described microcontroller Determine be couple to the charging contact of described first voltage and be couple to the charging contact of other contact switch elements described simultaneously with Described be electrically charged the first of end equipment and be electrically charged contact and described second be electrically charged the electrical contact of one of contact, described first numerical value is little In described second value, described second value is less than described third value.

For example, described first numerical value can be described second voltage, and described third value can be described first voltage, institute State the equipment recognition component that second value can depend on described first voltage, described second voltage and described charging end equipment With the described equipment being electrically charged end equipment is identified the resistance ratio between element, described equipment be identified element be coupled in described It is electrically charged the first of end equipment and is electrically charged contact and second and be electrically charged between contact.

Detect be electrically charged end equipment 200 and be linked in charging end equipment 100 when, microcontroller 125 can stop outer If detection operation, control and start to be charged to being electrically charged end equipment 200.Or, this microcontroller 125 can also be examined in peripheral hardware Survey after operation completes and in the case of detecting and being electrically charged end equipment 200, control and start to carry out to being electrically charged end equipment 200 Charge.Accordingly, it would be desirable to microcontroller 125 can control the break-make of charging voltage as needed, with protection circuit and user's peace Entirely.

For this reason, as shown in Fig. 2 in one embodiment, described control circuit 120 can also include：Charging switch element 123, the first end of described charging switch element is couple to the 3rd end of each contact switch element, and the second end is couple to described micro- Controller, the 3rd end is couple to described second voltage, and described charging switch element is used in described microcontroller Under control, the 3rd end of each contact switch element is couple to described second voltage or disconnects.

For example, this charging switch element 123 can be a N-channel junction field effect transistor (JFET), its coupling that drains It is connected to the lower pull end of contact switch element 121, grid is connected with microcontroller 125, and source electrode is couple to second voltage.Certainly, originally Application not limited to this.For example, this charging switch element 123 can also adopt other gate-controlled switches such as relay, audion Device is realizing.This charging switch element 123 can enter to being electrically charged end equipment 200 under the control of microcontroller 125 When row charges, contact switch element 121 is couple to second voltage.Additionally, when being electrically charged end equipment 200 charging complete or When being electrically charged end equipment 200 and being removed in charging end equipment 100, this charging switch element 123 can also be in microcontroller 125 Control under contact switch element 121 is disconnected with second voltage.

In order to prevent being electrically charged end equipment 200 charging complete, charging end equipment 100 is also persistently charged to it, Thus leading to power hungry and the battery being electrically charged end equipment 200 being caused damage, when charging detection charging process can be No end.

For this reason, as shown in Fig. 2 in one embodiment, described control circuit 120 can also include：Charging detecting element 124, described charging detecting element is resistance element, and its first end is couple to the 3rd end of described charging switch element, the second end It is couple to described second voltage.

For example, in order to avoid causing excessive power consumption, this charging detecting element 124 can be the less electricity of resistance Resistance, it can be identified the resistance of element much smaller than equipment recognition component 122 and equipment.For example, this charging detecting element 124 Resistance can be 0.8 Europe (Ω).

Correspondingly, described microcontroller 125 be additionally operable to described be electrically charged end equipment 200 and charge when, fill described in detection Magnitude of voltage at the first end of electrical detecting element 124, and in response to detecting at the first end of described charging detecting element Magnitude of voltage is reduced to a few predetermined value compared with when charging normal, and controls described charging switch element, so that described charging 3rd end of each contact switch element is disconnected by switch element with described second voltage.

In foregoing circuit structure, this equipment recognition component 122 can be connected in parallel on this charging switch element 123 and this charging The both sides of detecting element 124, or when omitting this charging detecting element 124, can be formed simultaneously with this charging switch element 123 Connection.

As shown in fig. 6, charging end equipment 100 includes 9 metal charging contact P1 to P9.It should be noted that Fig. 6 is Show the composition of charging end equipment 100 in circuit aspect, this 9 hard contacts array layout physically is not described. For example, depending on different product form and industrial design, spatially, they can be arranged in 3 row, 3 × 3 arrays of 3 row； The array of 2 row, the wherein the 1st 4 contacts of row, 5 contacts of the 2nd row can also be arranged in；May be arranged in the array of 4 row, its In 2 contacts of the 1st row, 2 contacts of the 2nd row, 3 contacts of the 3rd row, 2 contacts of the 4th row；Or other various forms.

9 metal charging contact P1 to P9 are electrically connected with 9 contact switch respectively, and each contact switch is respectively by two not The audion of same type is constituted, and that is, metal charging contact P1 corresponds to NPN type triode Q1 and PNP type triode Q2, and metal fills Electric contact P2 corresponds to NPN type triode Q3 and PNP type triode Q4 ... ..., and metal charging contact P9 corresponds to NPN type three pole Pipe Q17 and PNP type triode Q18.Each pair audion all in the form of cascode, wherein, the colelctor electrode of NPN transistor It is pulled upward to charging voltage VCC, the colelctor electrode of PNP transistor is via charge switch Q20 and detection resistance R2 (for example, 0.8 Ω) Pull down to ground voltage GND.The grid of every a pair of audion is connected with universal input/output (GPIO) interface of microcontroller U1 Connect.

As described above, in order to realize being electrically charged the detection of end equipment 200, being provided with identification resistance in charging end equipment 100 (for example, R1 (for example, 22k Ω), be correspondingly provided with identified resistance R3 between two contacts being electrically charged end equipment 200 22kΩ).So, by wiping contact array, access if there are being electrically charged end equipment 200, R1 and R3 will form bleeder circuit, It is electrically charged end equipment 200 by what the magnitude of voltage that the ADC pin of MCU detects R1 the 2nd end determined whether to meet charge condition. For example, if voltage R1 the 2nd end is detected is 0.5 times of VCC (when the resistance value of identification resistance R1 and identified resistance R3 is it When he is worth, VCC value according to both partial pressure), then explanation is electrically charged end equipment 200 and accesses, and now MCU can pass through Power Control pin will control Q20 to open charging.If detection voltage value is not 0.5 times of VCC, illustrate it is not to be filled Electric end equipment 200 accesses (such as it may be possible to short circuit metal, or other load conduction), at this moment will not open Q20 and be charged.

The process of scanning charging contact array is more specifically described below：MCU first passes through GPIO (Scan as depicted Control pin) control audion Q1 conducting, now P1 voltage in contact is about VCC, simultaneously MCU open in order respectively Q8, Q14, Q4, Q10, Q16, Q6, Q12, Q18, to make P2, P3, P4, P5, P6, P7, P8, P9 and GND turn on respectively, connect one every time During individual test point, MCU can read the voltage at R1 the 2nd end by ADC pin.If when sweeping to certain contact, ADC reads Voltage be GND, then judge now this contact not be electrically charged end equipment 200 and have turned on；If the voltage that ADC reads is VCC, then judge that now this contact and contact P1 have turned on it may be possible to be subject to be electrically charged some contact of end equipment 200 Short circuit, that is, this contact and contact P1 are made electrical contact with some contact being electrically charged end equipment 200 simultaneously；If the electricity that ADC reads Press as 0.5 times of VCC, then judge that now this contact has turned on being electrically charged end equipment 200, that is, this contact and contact P1 respectively with It is electrically charged two contact electrical contacts of end equipment 200.Above procedure by that analogy, completes the scanning of whole contacts matrix, until Find till being electrically charged end equipment 200 access.

For example, it is assumed that charging contact P1 and P4 of charging end equipment 100 and be electrically charged end equipment 200 first be electrically charged tactile Point electrical contact, and charging contact P9 and be electrically charged end equipment 200 second are electrically charged contact electrical contact.MCU controls three poles first Pipe Q1 turns on, and contact P1 is pulled upward to VCC, then MCU open in order respectively Q8, Q14, Q4, Q10, Q16, Q6, Q12, Q18, to pull down to GND by P2, P3, P4, P5, P6, P7, P8, P9 respectively.When P4 is pulled down to GND, MCU passes through ADC pin The magnitude of voltage read is VCC, now may determine that contact P1 and contact P4 by some contact being electrically charged end equipment 200 Short circuit.When P9 is pulled down to GND, the magnitude of voltage that MCU is read by ADC pin is 0.5 times of VCC, now may determine that Contact P9 is made electrical contact with another contact being electrically charged end equipment 200.So far, MCU finds that being electrically charged end equipment 200 accesses.

Detected be electrically charged end equipment 200 access charging end equipment 100 when or be fully completed it in scanning further Afterwards, MCU can open Q20 by GPIO pin Power Control and start to be charged to being electrically charged end equipment 200.Filling In the process of electricity, MCU timing can read R2 the 2nd end (because now Q20 is on, so being also R1 by ADC pin The voltage at the 2nd end) voltage.If the voltage that ADC reads is of substantially equal with when charging normal, illustrate that charging process is also continuing Continuous；If the voltage that ADC reads significantly reduces compared with when charging normal, illustrating to charge has completed；If ADC reads Voltage is 0, then explanation is electrically charged end equipment 200 and takes away from the charging panel of charging end equipment 100.

Complete or be electrically charged end equipment 200 to be taken away on charging panel in response to charging, MCU can pass through GPIO Pin Power Control closes Q20, with complete charge operation.

Obviously, foregoing circuit structure is only a kind of implementation of charging end equipment 100, and the application can also adopt it His circuit implementations.

As can be seen here, using the charging end equipment according to the embodiment of the present application, using some charging contacts and corresponding control Circuit processed it is achieved that arbitrarily placing when being electrically charged end equipment in the range of without departing from charging end device end, two equipment it Between can automatically set up charge circuit, then allow charging end equipment efficiently, safety, low cost, in contact to quilt Charging end equipment is charged.This mode had both had the convenience of current wireless charging, simultaneously the low one-tenth of wired charging again Basis and high efficiency.

Below, by refer to the attached drawing, continuing on end equipment 200 is electrically charged according to the embodiment of the present application.

Exemplary it is electrically charged end equipment

Being electrically charged end equipment 200 and can be charged by charging end equipment 100 according to the embodiment of the present application, described charging end sets Standby 100 can include multiple charging contacts.For example, this is electrically charged end equipment 200 can be can be electrically charged any kind of Electronic equipment, it includes but is not limited to：Notebook, panel computer, mobile phone, multimedia player, individual digital Assistant, navigator etc..

As shown in fig. 7, the described end equipment 200 that is electrically charged can include：First be electrically charged contact 211 and second be electrically charged tactile Point 212, is formed by conductive material.

For example, each be electrically charged contact 211 and 212 can be by conductive material systems such as metal, conductive plasticss or conductive rubbers Become.Meanwhile, in order to avoid being short-circuited when charging, two be electrically charged between contact can be spaced a distance.

Due to when charging end equipment 100 is with being electrically charged end equipment 200 and being connected, directly not determining that the first charging is touched Which in point set and the second charging contact set is to be electrically charged contact 211 and second with first to be electrically charged in contact 212 Which electrical contact, also just so that do not know be with the positive charged terminal and negative pole charging end of load circuit 230 in which One electrical connection, so be only to the first charging contact set and the second charging contact set in charging end equipment 100 One of distribution high voltage and to another distribute low-voltage, start charge.In this case it is desirable to ensure that being electrically charged end sets Standby 200 will not fail to charge normal or even occur burning out load circuit 230 because charging voltage is reversed.

For this reason, as shown in fig. 7, in one embodiment, described control circuit 120 can also include：Rectification circuit 220, It is electrically charged contact, described second is electrically charged contact and the positive charged terminal of described load circuit and negative pole fills with described first The electrical connection of electric end, for being electrically charged, by being electrically charged contact and described second from described first respectively, the first voltage that contact receives It is couple to described positive charged terminal with the high voltage in second voltage, and will be low in described first voltage and described second voltage Voltage is couple to described negative pole charging end.

By being electrically charged outfit rectification circuit 220 in end equipment 200 it is ensured that correct charging voltage is connected to Correct charging end on load circuit 230.

For example, this rectification circuit 220 can be realized using the device of such as rectifier bridge etc.Rectifier bridge is by two poles Completing rectifying operation, so being accessed when being electrically charged in end equipment 200, it can make in circuit the one-way conduction principle of pipe Charging current only press one-way flow, that is, charging current flows into from the positive charged terminal of load circuit 230, from negative pole charging end stream Go out, play so-called " rectification " effect.

Alternatively, rectification circuit 220 can also be realized using other modes.For example, rectification circuit 220 can also include Microcontroller and switch element, identify that by microcontroller being electrically charged contact and described second from described first is electrically charged contact High voltage in the first voltage and second voltage that receive and low-voltage, and by switch element, high voltage is couple to described Positive charged terminal, and low-voltage is couple to described negative pole charging end.

Specifically, rectification circuit 220 can include：First load switching element and the second load switching element, described The first end of one load switching element is couple to described positive charged terminal, and the second end is couple to described first and is electrically charged contact, the Three ends are couple to described negative pole charging end, and the first end of described second load switching element is couple to described positive charged terminal, the Two ends are couple to described second and are electrically charged contact, and the 3rd end is couple to described negative pole charging end, described first load switching element It is all the responsible control electric current break-make being made up of at least one electronic device with each of described second load switching element Element circuit；And microcontroller, it is couple to the 4th end of described first load switching element and described second load switch 4th end of element, and be couple to described first and be electrically charged contact and described second and be electrically charged contact, in response to detection Go out the high voltage in described first voltage and described second voltage and low-voltage, control described first load switching element and described Second load switching element, so that described high voltage is couple to described positive charged terminal, and described low-voltage is couple to Described negative pole charging end.

For example, each load switching element is electrically charged contact 211 and described second for control from described first and is electrically charged The positive charged terminal to load circuit 230 for the first voltage and second voltage that contact 212 receives and the electric current of negative pole charging end Break-make.For example, it can include a pair of switches device, and each of first voltage and second voltage are connected respectively to positive pole Charging end and negative pole charging end.For example, to being two NMOS tube, its drain electrode is coupled together this switching device, source electrode coupling It is connected to ground voltage, grid is respectively coupled to microcontroller (MCU), controlled their conducting by MCU by single logic respectively Operate with turning off.Or, the grid of two NMOS tube can also be commonly connected to microcontroller (MCU), and passes through therebetween Phase inverter separately, with by MCU pass through a logic control in them one conducting and another one turn off operation.However, the application Not limited to this.As described in exemplary charging end equipment, each switching device can also adopt such as audion, relay Other gate-controlled switch devices of device or N knife M throw switch etc are realizing.

Microcontroller can be used for producing the control logic for load switching element, in response to detecting from first Be electrically charged contact and second be electrically charged in the first voltage that contact receives and second voltage which be high voltage and which For low-voltage, to control the break-make of load switching element, high voltage to be connected to positive charged terminal and low-voltage is connected to Negative pole charging end.For this reason, microcontroller can be 51 single-chip microcomputers, the microcontroller based on 8 Atmel AT MEGA328P, STC STM8 etc..
