Abstract
The utility model relates to a power supply device. The power supply device comprises a power management unit, an internal power supply unit, first control switches for controlling the make-and-break of a circuit; a charging circuit and a build-in detection circuit are arranged between the internal power supply unit and the power management unit; an internal power supply circuit is arranged between the internal power supply unit and a work unit; and the first control switches are arranged on both the build-in detection circuit and the internal power supply circuit. When an internal battery is not used, the first control switches are switched off, and the internal power supply circuit is cut off, so that the service life of the battery is prolonged and the reliability of external power supply is improved. The utility model complements the switching of software controlled internal and external power supplies; and under the conditions of packaging and transportation, the first control switches are switched off, and the internal power supply circuit is cut off, so the battery can be transported safely even mounted in an internal power supply unit of a terminal or electronic equipment, and the transportation safety is high.
Description
Technical field
The utility model relates to the electric supply installation field on mobile communication terminal and the portable electric appts.
Background technology
In wireless terminal product such as mobile phone, notebook computer, handheld device, MP3 or portable type electronic product, all include to its working cell electric supply installation of power supplies such as CPU, display module, audio-frequency module for example.At present, general electric supply installation as shown in Figure 1, comprise administrative unit 1 and in-line power unit 2 realize externally fed function that working cell 3 is powered and in-line power function, and by the battery charging function of administrative unit 1 in the in-line power unit 2 of packing into.Wherein, Power Management Unit 1 is used for the access of external power source.Said externally fed is meant that external power source passes through Power Management Unit 1 and directly powers to working cell 3.Simultaneously, directly supervise 1 pair of working cell 3 of Power Management Unit.Said in-line power is meant by the battery of the in-line power unit of packing into and powers to working cell 3 by the in-line power circuit.Switching between externally fed and the in-line power is to realize by the software in the administrative unit 1.Be meant that in said charging Power Management Unit 1 charges by the battery of charging circuit in the in-line power unit 2 of packing into.Simultaneously, Power Management Unit 1 also detects by the charged state of built-in testing circuit to battery; After battery completely filled, Power Management Unit 1 was also cut off charging circuit automatically by software control.
Yet, development along with the miniaturization of products, the volume of battery of packing in the in-line power unit is done littler and littler, cause the cycle life of battery limited, if only switch the inside and outside power supply by software control, the durability of battery can be difficult to be guaranteed, and influences user's experience, therefore, present electric supply installation is still waiting further improvement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of and can prolong the battery electric supply installation in useful life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric supply installation comprises first control switch of Power Management Unit, in-line power unit, control circuit break-make; Be provided with charging circuit and built-in testing circuit between described in-line power unit and the described Power Management Unit, be provided with the in-line power circuit between described in-line power unit and the working cell; On described built-in testing circuit and the described in-line power circuit described first control switch is set all.
The beneficial effects of the utility model are: by on built-in testing circuit and in-line power circuit first control switch being set, the in-line power unit is disconnected with the built-in testing circuit of Power Management Unit and working cell physically, thereby stop the charging detection physically and stop using the in-line power function, so that only use the externally fed function.Like this, under the battery cycle life condition of limited, reduce the access times of battery, pack into battery independence support time of in-line power unit with prolongation.It and software control inside and outside power supply switch and form complementation, and both are not mutually exclusive.When normally and often not having external power supply, use software control.When not needing to use internal cell in that the stable external power supply is arranged, can be by first control switch thorough breaking inner power supply circuits physically, prolonged battery useful life, improve the reliability of externally fed simultaneously.In addition, under the condition of packed and transported, first control switch is disconnected, cut off the in-line power circuit,, also can transport the Transport Safety height safely even battery is contained in the in-line power unit on terminal or the electronic equipment.The equipment of inside and outside power supply of any needs all can adopt electric supply installation of the present utility model.

Embodiment
Execution mode one
As shown in Figure 2, the present embodiment electric supply installation comprises first control switch 8 of Power Management Unit 5, in-line power list 6, control circuit break-make.In-line power unit 6 is used to the battery of packing into, is provided with charging circuit 56 and built-in testing circuit 65 between it and the Power Management Unit 5, and is provided with in-line power circuit 67 between the working cell 7.First control switch 8 all is set on built-in testing circuit 65 and the in-line power circuit 67.First control switch 8 can be selected two single knife switches for use, and is easy to operate; Also can select a double-pole switch for use, more convenient operation.Present embodiment is selected double-pole switch as shown in Figure 3 for use, and this double-pole switch comprises that the battery detecting utmost point 81 and charging detect the utmost point 83, the powered battery utmost point 82 and the current absorption utmost point 84.
By first control switch 8 is set on built-in testing circuit 65 and in-line power circuit 67, in-line power unit 6 is disconnected with the built-in testing circuit 65 of Power Management Unit 5 and working cell 7 physically, thereby stop the charging detection physically and stop using the in-line power function, so that only use the externally fed function.Like this, under the battery cycle life condition of limited, reduce the access times of battery, pack into battery independence support time of in-line power unit 6 with prolongation.It and software control inside and outside power supply switch and form complementation, and both are not mutually exclusive.When normally and often not having external power supply, use software control.When not needing to use internal cell in that the stable external power supply is arranged, can be by first control switch 8 thorough breaking inner power supply circuits 67 physically, prolonged battery useful life, improve the reliability of externally fed simultaneously.In addition, under the condition of packed and transported, first control switch is disconnected, cut off in-line power circuit 67,, also can transport the Transport Safety height safely even battery is contained in the in-line power unit 6 on terminal or the electronic equipment.The equipment of inside and outside power supply of any needs all can adopt electric supply installation of the present utility model.
Execution mode two
