Description

The battery of mobile phone that has the PDA function

[technical field]

This patent relates to especially battery of mobile phone technology of battery.

[background technology]

Along with the fast development of the communication technology, increase rapidly for the demand of GSM/GPRS/CDMA mobile phone, each producer increases various functions one after another in order to contend for markets on mobile phone, to attract the consumer, occurred the demand of mobile phone belt PDA function at present again.Because for the GSM/GPRS/CDMA mobile phone, almost major part all possesses the receiving short message function is arranged, and short message input without exception use keypad almost, not only input information difficulty, and telephone number searching is also slow, storage capacity is little, and deficiencies such as expansion difficulty are difficult to be resolved.If in the GSM/GPRS/CDMA mobile phone, increase the PDA functional unit, not only among the PDA hand-write input function arranged, and very big storage volume is arranged.

But the core technology of GSM/GPRS/CDMA mobile phone as: communications protocol software, radio-frequency technique and chip technology etc. are still grasped by external limited several big trans-corporation basically, increase the PDA function and must cross over technology barriers on the mobile phone core technology in the GSM/GPRS/CDMA mobile phone.On the other hand, promptly allowing to increases the PDA function in the GSM/GPRS/CDMA mobile phone, must increase the cost of GSM/GPRS/CDMA mobile phone itself greatly, so is difficult to again meet customer need well.

[summary of the invention]

The utility model purpose is the deficiency at existing GSM/GPRS/CDMA mobile phone technique, and a kind of battery of mobile phone of the PDA of having function is provided, and makes the function of GSM/GPRS/CDMA mobile phone obtain low-cost expansion, to satisfy user's demand.

The purpose of this utility model is achieved in that and makes up a kind of battery of mobile phone with the PDA function, comprises rechargeable battery, it is characterized in that, also comprises Voltage stabilizing module, is connected with the output of rechargeable battery; The PDA functional unit is connected with the output of Voltage stabilizing module.

The utility model is because taked technique scheme, under the prerequisite of the design that need not change mobile phone inside, functional structure by additional battery of mobile phone realizes that mobile phone possesses the main or repertoire of PDA, thereby easily walk around the technology barriers in the mobile phone technique, can better satisfy the demands of consumers with lower cost.

[embodiment]

Below in conjunction with drawings and Examples the utility model is further elaborated.

As depicted in figs. 1 and 2, the battery of mobile phone that has a PDA function comprises rechargeable battery 1; Voltage stabilizing module 20 is connected with the output of rechargeable battery 1; PDA functional unit 2 is connected with the output of Voltage stabilizing module 20.Rechargeable battery 1 and Voltage stabilizing module 20, PDA functional unit 2 are chimeric to be one.In the battery of mobile phone of the band PDA function that present embodiment provides, PDA functional module 2 is embedded in the rechargeable battery 1, behind the mobile phone of packing into, the display screen of PDA functional module is exposed to the back side of mobile phone, and rechargeable battery 1 gives mobile phone 3 power supplies simultaneously.PDA functional unit 2 can also and mobile phone 3 between realize communication linkage.Rechargeable battery body 1 with its on embedded PDA functional unit can be as a whole, also can be for loading and unloading.

As shown in Figure 3 and Figure 4, be provided with MCU microprocessor 207 in the PDA functional unit 2, the built-in infrared communication interface 203 of MCU is by communication link wiring 210 control infrared communication module 209 and mobile communications.After battery of mobile phone 1 is handled by power supply step-down module (LDO) 208 step-downs on electric power connection line 11 and the PDA functional unit 2, on the PDA functional unit 2 each parts power supply is provided.Electric power connection line 11 is made up of two lines: positive source (V+) and power cathode (GND).Communication link wiring 210 is made up of five lines: give the positive source (VCC) of infrared communication module 209 power supplies, and communication enabling signal (EN), data send holding wire (TX), data reception signal line (RX) and ground wire (GND).

The utility model is when making PDA and use and traditional PDA and indistinction, and PDA can break away from mobile phone to be used separately.When needing, the charger of mobile phone charges to PDA by mobile phone.

The mobile phone that is used with the utility model and traditional mobile phone are just the same, can also can use general battery with the PDA battery, and the charger of mobile phone can be given by mobile phone and embed the battery charge that be with PDA.

The utility model there is no big difference with original mobile phone or PDA as mobile phone or PDA use the time, just function expands, and has become the PDA mobile phone.When the needs input information, can be directly with pen handwriting input on the LCDs that has touch sense function on the PDA, and information is shown by master control chip MCU control LCDs.When needs use GB2312 Chinese character base, english Chinese dictionary, handwriting recognition storehouse, the corresponding item earlier of available pen point is by MCU reading of data from FLASH.During when needs transmitting-receivings and storage short message, fax, Email with from the Internet download information, can control FLASH, RAM, infrared communication interface, communication link wiring and infrared communication module and handset switch information by MCU.

This patent has several advantages.Described PDA mobile phone is stronger than conventional incorporate PDA cell-phone function, just may realize the PDA cell-phone function as long as change a battery at the no PDA mobile phone that uses, and cost is low and simple.By giving the PDA functional unit 2 power supplies by means of GSM/GPRS/CDMA battery of mobile phone 1, saved a whole set of Charge Management scheme (AC/DC charger+Charge Management+charge protection), make things convenient for the user to carry.Because the hand-write input function in the PDA functional unit 2 makes things convenient for the input of information, and utilize the big memory body storage user's data of PDA.The infrared communication interface exchange message of GSM/GPRS/CDMA mobile phone and PDA, can realize sending and receiving e-mail, fax sending and receiving, transmitting-receiving SMS, realize the remote download function by the Internet, and the business card of GSM/GPRS/CDMA mobile phone inside can also back up in PDA.
