Embodiment
The present invention will be described below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, wherein Fig. 1 is the perspective view of cells in notebook computer module first embodiment of the present invention, and Fig. 2 is the circuit diagram that cells in notebook computer module shown in Figure 1 inserts load.This cells in notebook computer module 1 comprises shell 10, a plurality of electric core 12, gauge tap 14, DC voltage converting circuit 16 and general connecting interface 18.This shell 10 forms a receiving space, and takes in these a plurality of electric cores 12, this gauge tap 14, this DC voltage converting circuit 16 and this general connecting interface 18.
This shell 10 also is formed with a plurality of windows (indicating) on its surface, this gauge tap 14 is exposed to this shell 10 surfaces by wherein a window is little, so that this gauge tap 14 can the closed or shutoff from outer setting.In the present embodiment, this gauge tap 14 is a slide switch, promptly the part that is exposed to these shell 10 surfaces by slip is controlled the closed of this gauge tap 14 or is turn-offed, and according to the different designs demand of product, this gauge tap 14 can also be designed to push type even touch.
This general connecting interface 18 is realized external connection by the window on these shell 10 surfaces equally, for the different portable electronic products of compatibility, this general connecting interface 18 is the common connecting interface of industry, for example USB A type interface, 1394 interfaces etc., in the present embodiment, this general connecting interface 18 is a USB A type interface, and its quantity can be one, two even a plurality of, decides on the product design demand.This general connecting interface 18 is owing to just be used for the portable electronic products discharge, and do not carry out data transmission, therefore, the transmitting electrode line of power supply usefulness can only only be set in this general connecting interface 18, and data electrode wire need not be set.Further improving in the design; can also protected location be set on the surface of this general connecting interface 18; for example protect slip lid or protection rubber, to stop extraneous dust, water droplet and dirt to block this general connecting interface 18 even to enter this cells in notebook computer module 1 inside.
The main effect of these a plurality of electric cores 12 is that the charging back powers to exterior terminal, these a plurality of electric cores 12 are connected mutually and are arranged in parallel, the electric core group that for example some electric core 12 series connection form is in parallel with other same electric core group again, it is chargeable electric core (rechargeable battery), usually quantity is between 3～9 joints, can certainly be still less, as 2 joints in addition only 1 joint all can.In the present embodiment, this cells in notebook computer module 1 comprises 9 economize on electricity cores 12, that is common 9 alleged core battery modules, and its charging capacity can reach 7800mAh.When this cells in notebook computer module 1 charged in notebook computer, the charge-discharge protection circuit of the embedded controller of itself and notebook computer (EC, figure does not show) electrically connected, to realize the safe charging to these a plurality of electric cores 12.
This DC voltage converting circuit 16 and these a plurality of electric cores 12 are connected in series, and carry out boost conversion or step-down conversion with DC voltage that these a plurality of electric cores 12 are externally exported, thereby make its external output voltage be fit to portable electronic products to be charged.For example, the external output voltage of these a plurality of electric cores 12 is between between the 10V to 20V, and the charging voltage of portable electronic products to be charged is 5V, and then the external output voltage that this DC voltage converting circuit 16 will these a plurality of electric cores 12 is reduced to the 5V DC voltage.
In addition, further improving in the design, these a plurality of electric cores 12 can also be connected with a discharge protection circuit (figure does not show), to control the discharge process of these a plurality of electric cores 12, avoid over-discharge can to cause the capacity of these a plurality of electric cores 12 impaired.
When portable electronic products 19 needs charging, can comparatively easily this cells in notebook computer module 1 be taken off, by this general connecting interface 18 this portable electronic products 19 is connected to this cells in notebook computer module 1, and makes this gauge tap 14 be in closure state.This moment these a plurality of electric core 12 external output dc voltages, this DC voltage converting circuit 16 is carried out voltage transitions with this DC voltage, and pass through these general connecting interface 18 output dc voltages and give this portable electronic products 19 chargings with power supply, in the present embodiment, this cells in notebook computer module 1 can externally be exported the direct current of 5V, 500mA.In order to adapt to the charging of more portable electronic products, this DC voltage converting circuit 16 can provide multiple voltage, electric current output specification, because correlation technique is comparatively ripe, does not give unnecessary details at this.
The battery capacity of common portable electronic products is generally 500mAh to 1500mAh, so, this cells in notebook computer module 1 can be realized repeatedly externally powering, and when it is externally powered, do not need to open notebook computer, avoid the inessential waste of energy of irrelevant electronic component, therefore greatly improved the convenience and the electric energy service efficiency of working trip.
See also Fig. 3 and Fig. 4, wherein Fig. 3 is the perspective view of cells in notebook computer module second embodiment of the present invention, and Fig. 4 is that cells in notebook computer module shown in Figure 3 inserts the circuit diagram that load is charged.The cells in notebook computer module 2 of present embodiment and cells in notebook computer module 1 broadly similar in first embodiment, its key distinction is: except shell 20, a plurality of electric core 22, gauge tap 24 and general connecting interface 28, this cells in notebook computer module 2 further comprises ac/dc (AC/DC) voltage conversion circuit 23 and AC power input and output interfaces 25, so that this cells in notebook computer module 2 can provide Alternating Current Power Supply for portable electronic products 29, and this gauge tap 24 is a two-way switch.
As shown in Figure 4, the DC voltage of externally exporting from these a plurality of electric cores 22 is converted to the charging voltage of portable electronic products through DC voltage converting circuit 26.When this portable electronic products 29 needed DC voltage, it was connected with this cells in notebook computer module 2 by this general connecting interface 28, these gauge tap 24 direct closed article one branch roads, i.e. situation described in first embodiment.When this portable electronic products 29 needs alternating voltage, it is connected with this cells in notebook computer module 2 by this AC power output interface 25, these gauge tap 24 disconnected second branch roads that close, at this moment, this ac/dc voltage conversion circuit 23 is converted to alternating voltage with DC voltage, offer this portable electronic products 29 again, thereby satisfy the power demands of AC load, further expand the function of this cells in notebook computer module 2.
Only be preferred case study on implementation of the present invention below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
