Description
Technical field
The utility model relates to landline telephone, particularly a kind of cellular phone.
Background technology
Current cellular phone internal integration has Modem(modulator-demodulator), except voice call service can be provided, also can by data wire, be connected and accessing Internet with computer using cellular phone as a Modem, accept the data, services of lightweight.In addition, then without other function, compare with mobile phone, function singleness, lacks attraction; Compare with normal telephone, high expensive, does not have competitive advantage.Because cellular phone enclosure volume is larger, built-in rechargeable battery, and external power supply, therefore, this equipment also has larger functional promotion space.
Summary of the invention
The purpose of this utility model is to promote existing fixed CDMA WLL function, and a kind of cellular phone that can charge to portable digital product is provided.
A kind of cellular phone, it comprises wireless fixed telephone and power supply adaptor, the lithium cell charging administration module that described base is built-in with the communication module that can communicate by letter with mobile radio networks, the power module that can be connected with civil power by external power adapter, the rechargeable battery being connected with described power module and is connected with power module outlet, the output of described lithium cell charging administration module is also connected with a plurality of charging inlets.Described lithium cell charging administration module comprises a plurality of voltage conversion circuits and is connected to a plurality of Charge Managements and protective circuit thereafter, and described a plurality of charging inlets are connected with protective circuit with corresponding Charge Management respectively.
Cellular phone of the present utility model has utilized fixed CDMA WLL device to need the feature of external power adapter and built-in rechargeable battery, expands to the function that portable digital electronic product charges.This is a practical function, well-known, and current digital electronic goods miscellaneous are more and more, and they use rechargeable battery power supply mostly.User often faces again the awkward situation that can not find charger when another without electric when using digital electronic goods, at this time just can use easily in family the charger function in fixed CDMA WLL device.The product of this case can provide charging service for multiple different digital product, is equivalent to the charger function of a plurality of different products to be incorporated into the housings of fixed CDMA WLL, has improved the utilance of cellular phone, has saved resource and space.
Accompanying drawing explanation
Fig. 1 is the application principle block diagram of the cellular phone of an embodiment.
Fig. 2 is the structure principle chart of the lithium cell charging administration module of cellular phone in an embodiment.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the utility model cellular phone is described in further detail.
As shown in Figure 1, in an embodiment, cellular phone mainly comprises wireless fixed telephone and power supply adaptor.Wireless fixed telephone can be by a power supply adaptor access civil power AC.The effect of power supply adaptor is civil power alternating current to be converted to direct current be supplied to base.Communication module, power module, rechargeable battery, lithium cell charging administration module and a plurality of charging inlet (charging inlet 1, charging inlet 2 are set in base ... charging inlet N, N is integer).
Wherein, communication module can be communicated by letter with mobile radio networks, realizes the function of mobile fixed-line.
Power module input is connected with power supply adaptor output, and it supplies with communication module, rechargeable battery and lithium cell charging administration module for the direct current of power supply adaptor output is converted to suitable voltage.When causing power supply adaptor no-output because of reasons such as power failures, the built-in rechargeable battery of fixed CDMA WLL can be that communication module and lithium cell charging administration module are powered by power module, thereby can under power down mode, maintain communication service and provide emergent charging service to outside portable digital electronic product.
Lithium cell charging administration module is used for the output of power module to be converted to the charging voltage that is applicable to different portable digital electronic products, and exports corresponding charging inlet to.The charging circuit of different portable digital electronic products is comparative maturity all, generally includes voltage conversion circuit and Charge Management and the protection circuit of connection.Specifically with reference to figure 2; lithium cell charging administration module comprises a plurality of voltage conversion circuits (voltage conversion circuit 1, voltage conversion circuit 2 ... voltage conversion circuit N; N is integer); and a plurality of Charge Managements and protection circuit (Charge Management and protection circuit 1, Charge Management and the protection circuit 2 that are connected to the plurality of voltage conversion circuit output ... Charge Management and protection circuit N, N is integer).Wherein, voltage conversion circuit can be booster circuit or reduction voltage circuit.The defencive functions such as Charge Management and protection circuit have Charge Management and overcharge, excessively put, overcurrent, short circuit.A plurality of charging inlets are connected with protective circuit with corresponding Charge Management respectively.A plurality of charging inlets are drawn from the shell of base by electric wire, preferably from the sidewall of shell, draw.
Cellular phone of the present utility model has utilized fixed CDMA WLL device to need the feature of external power adapter and built-in chargeable lithium cell, expands to the function that portable digital electronic product charges.This is a practical function, well-known, and current digital electronic goods miscellaneous are more and more, and they use rechargeable battery power supply mostly.User often faces again the awkward situation that can not find charger when another without electric when using digital electronic goods, at this time just can use easily in family the charger function in fixed CDMA WLL device.The product of this case can provide charging service for multiple different digital product, is equivalent to the charger function of a plurality of different products to be incorporated into the housings of fixed CDMA WLL, has improved the utilance of cellular phone, has saved resource and space.When mains failure, can also utilize rechargeable battery in cellular phone to charge for portable digital electronic product, very easy to use.
Although description of the present utility model is carried out in conjunction with above specific embodiment,, those skilled in the art can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all such substituting, improve and change are all included in the spirit and scope of attached claim.
