Summary of the invention
The technical problems to be solved in the utility model is, a kind of cells in notebook computer power supply is provided, and makes the user can further alleviate notebook computer weight, causes the risk of loss of data when avoiding notebook computer to be used in sudden power simultaneously.
The technical scheme that its technical matters that solves the utility model adopts is: construct a kind of cells in notebook computer power supply, it is characterized in that, comprise first rechargeable battery and second rechargeable battery that are connected in parallel in the notebook computer, described second rechargeable battery is arranged in the battery case of notebook computer and detachable.
In cells in notebook computer power supply described in the utility model, described first rechargeable battery is fixedly installed in the notebook computer, and on the positive terminal circuit of described first rechargeable battery or on the negative pole end circuit Live switch is being set.
In cells in notebook computer power supply described in the utility model, described first rechargeable battery is arranged in the battery case of notebook computer and is detachable.
In cells in notebook computer power supply described in the utility model, described first rechargeable battery and second rechargeable battery are arranged in the same battery case of notebook computer and are all detachable, and described cells in notebook computer power supply comprises the device that is connected in parallel between described first rechargeable battery and second rechargeable battery; This device one end that is connected in parallel connects the positive pole of described first rechargeable battery and the positive pole of second rechargeable battery respectively, the other end is connected in the circuit of notebook computer, maybe this device one end that is connected in parallel connects the negative pole of described first rechargeable battery and the negative pole of second rechargeable battery respectively, and the other end is connected in the circuit of notebook computer.
In cells in notebook computer power supply described in the utility model, the described first rechargeable battery capacity is less than the described second rechargeable battery capacity.
Implement cells in notebook computer power supply of the present utility model, compared with the prior art, its beneficial effect is:
1, owing to adopts double cell power supply architecture in parallel, a battery is installed on the notebook computer for a long time, but there is being the external power supply time spent, another battery is pulled down from notebook computer, can further alleviate the weight of notebook computer, and cause the loss of data of notebook computer can prevent sudden power the time;
2, the battery of pulling down can be avoided working under hot environment for a long time, prolongs the life-span of pulling down battery.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the synoptic diagram of notebook computer and existing battery thereof.
Fig. 2 is the utility model cells in notebook computer power-supply battery synoptic diagram.
Fig. 3 is embodiment one synoptic diagram of the utility model cells in notebook computer power supply.
Embodiment
Embodiment one
As Fig. 2, shown in Figure 3, cells in notebook computer power supply of the present utility model comprises first rechargeable battery 31 and second rechargeable battery 32, first rechargeable battery 31 and second rechargeable battery 32 are connected in parallel in by the coupling arrangement between two batteries 33 in the same battery case of notebook computer, and first rechargeable battery 31 and second rechargeable battery 32 all can take apart from battery case easily.
Wherein, coupling arrangement 33 1 ends connect the positive pole of first rechargeable battery 31 and the positive pole of second rechargeable battery 32 respectively, the other end is connected in the circuit of notebook computer, or coupling arrangement 33 1 ends connect the negative pole of first rechargeable battery 31 and the negative pole of second rechargeable battery 32 respectively, and the other end is connected in the circuit of notebook computer.
In other embodiments, coupling arrangement 33 can be fixedly installed on the notebook computer, and coupling arrangement 33 is separated into two battery cases with battery case, and first rechargeable battery 31 and second rechargeable battery 32 distribute and be installed in two battery cases.
In the use, first rechargeable battery 31 is installed on the notebook computer for a long time, but has external power supply time spent second rechargeable battery 32 to pull down preservation at notebook computer, to alleviate the weight of notebook computer, prolongs the life-span of second rechargeable battery 32 simultaneously.
The function of first rechargeable battery 31 is to prevent that sudden power from causing the notebook computer loss of data, its required battery capacity is less, but the function of second rechargeable battery 32 is not have the external power supply time spent as main power supply at notebook computer, and the big more support working with notebook computer time of its battery capacity is long more.Therefore, common first rechargeable battery 31 is designed to small-capacity cells, and second rechargeable battery 32 is counted high capacity cell.
Certainly, first rechargeable battery 31 and second rechargeable battery 32 also can be designed as the battery of same structure and same capability, first rechargeable battery 31 and second rechargeable battery 32 can be with exchanging in the use, like this, not only reduced cell types, also improve the interchangeability of battery, simplified the spare and accessory parts supply of notebook computer.
