Description
Technical field
The utility model is a kind of shared interface arrangement, refers to a kind of device that makes portable electronic unit and peripherals share interface especially.
Background technology
At present in small-sized portable electronic unit on the market, as PDA(Personal Digital Assistant) or mobile phone etc., if use with the collocation of peripherals such as keyboard, because external restriction, Shang Weiyou is defined in the data signal line and the power lead of portable electronic unit on the same pin position, selects power supply function or carries out the one-way data transfer function because generally only consider in design.
See also Fig. 1, when if this device will use this to send data and power supply (TxD/POWER) stitch bit function simultaneously, promptly have the phase collision problem, because of when power supply (POWER) the line function of portable electronic unit 1a is used in peripherals 2a selection, this peripherals 2a only can carry out the one-way data transmission to portable electronic unit 1a by transmission data (TxD) line of peripherals 2a, can not carry out data double-way with portable electronic unit 1a and link up:
When if this peripherals 2a selects to use transmission data (TxD) the line function of portable electronic unit 1a, peripherals 2a then wants other its power for operation of power autonomous confession, so, loses its due convenience on the contrary.
Summary of the invention
A purpose of the present utility model, be to provide one can make power lead and the simultaneous interface arrangement of data line, its be make a switch element and discharge and recharge assembly be connected to the transmission data/power supply stitch position of portable electronic unit and peripherals power supply, receive between the data line, when this transmission data/when power supply stitch position does not have data transmission at high levle, the switch element conducting, so that peripheral equipment power to be provided, and to discharging and recharging the assembly charging; Send data/power supply stitch position at low level as data transmission, switch element then ends, and avoids power supply (VCC) the pin position of peripherals to be become low level.At this moment, this discharges and recharges assembly and can be used as reserve battery, uses the electric power discharge and recharge on the assembly for peripherals, otherwise this sends data/power supply stitch position when high levle, the switch element conducting, and so that peripheral equipment power to be provided, and to discharging and recharging the assembly charging.
In sum, by circuit design of the present utility model, have following beneficial effect:
1, power supply and data signal line function are existed simultaneously, and can not conflict mutually.
2, can carry out data double-way links up.
3, need not be power autonomous, the tool convenience.

Embodiment
See also Fig. 2, the utility model is a shared interface arrangement, be connected in a portable electronic unit 1 and with transmission data/power supply (TxD/POWER) stitch position and have between the peripherals 2 of power supply (VCC) and reception data (RxD) line, comprise that a switch element 3 and discharges and recharges assembly 4.
Aforesaid portable electronic unit 1 is a personal digital assistant or mobile phone etc., it in embodiment of the present utility model personal digital assistant, it has the connector 11 of one or eight leg positions, and the pin bit function of this connector 11 has reception data (RxD), synchronization to interrupt (HSI), signal ground and sends data/power supply (TxD/POWER) etc.
This switch element 3 is diodes, the one end is connected to transmission data/power supply (TxD/POWER) the stitch position of portable electronic unit 1 and reception data (RxD) line of peripherals 2 altogether, end is to be connected with the power supply (VCC) of peripherals 2 in addition, this switch element 3 is to send data/conducting when the power supply stitch is positioned at high levle, and ends when low level.
This discharges and recharges assembly 4 is electrochemical capacitors, and the one end is the power supply (VCC) that is connected in peripherals 2, and other holds ground connection, and this discharges and recharges assembly 4 is to charge when switch element 3 conductings, and when switch element 3 ends, is used as standby power supply, uses for peripherals 2.This discharges and recharges speed, the low level length of assembly 4 values must transmit on data the time and decides, before voltage end on discharging and recharging assembly 4 is discharged to the required minimum voltage of peripherals 2, transmission data/power supply stitch position in portable electronic unit 1 must be transformed into high levle, to discharging and recharging assembly 4 chargings, therefore, the speed that transmits is slow more, and it is big more to discharge and recharge assembly 4 values.
See also Fig. 3 and Fig. 4, be action diagram of the present utility model, when transmission data/power supply (TxD/POWER) stitch position of portable electronic unit 1 does not have data transmission at high levle, diode 3 conductings, peripherals 2 power supplys (VCC) are provided, and to discharging and recharging assembly 4 chargings.
As data transmission and transmission data/power supply (TxD/POWER) stitch position of portable electronic unit 1 during at low level, diode 3 is to be cut-off state, at this moment, this discharges and recharges assembly 4 and can be used as reserve battery, uses the electric power that discharges and recharges on the assembly 4 for this peripherals 2;
As data transmission and transmission data/power supply (TxD/POWER) stitch position of portable electronic unit 1 during at high levle, diode 3 is to be conducting state, and peripherals 2 power supplys (VCC) are provided, and to discharging and recharging assembly 4 chargings.
Seeing also Fig. 5, is another synoptic diagram of the present utility model.Wherein switch element 3 is transistors of a positive-negative-positive, and the base stage of this transistor 3 is to be connected with a resistance R one end, and resistance R is held ground connection in addition; The collection utmost point of transistor 3 is to be connected with the power supply (VCC) that supplies peripherals 2, and the emitter-base bandgap grading of transistor 3 is to be connected with transmission data/power supply (TxD/POWER) the stitch position of portable electronic unit 1 and reception data (RxD) line of peripherals 2.
When portable electronic unit 1 the transmission data/when power supply stitch position did not have data transmission at high levle, transistor 3 conductings provided peripherals 2 power supplys (VCC), and to discharging and recharging assembly 4 charging.
As data transmission and the transmission data/power supply stitch position of portable electronic unit 1 during at low level, transistor 3 is to be cut-off state, and at this moment, this discharges and recharges assembly 4 and can be used as reserve battery, uses the electric power that discharges and recharges on the assembly 4 for this peripherals 2:
As data transmission and the transmission data/power supply stitch position of portable electronic unit 1 during at high levle, transistor 3 is to be conducting state, and peripherals 2 power supplys (VCC) are provided, and to discharging and recharging assembly 4 chargings.
Certainly, also available other of above-mentioned this switch element has conducting and the control piece that ends function, all can be encompassed within the claim of the present utility model.
