Description
Technical field
The battery pack of the relevant a kind of Portable electric equipment of the present invention, particularly relevant a kind of battery component of pegging graft and expanding is in order to supply this Portable electric equipment required working power.
Background technology
The application of Portable electric equipment in the society of industry and commerce now is more prevalent, and for example most typical Portable electric equipment includes notebook computer, portable communication apparatus, Portable checkout equipment, Portable audio-visual equipment etc.By the use of these Portable electric equipments or auxiliary, can be so that the user obtains maximum operating efficiency, best commercial activity effect and living condition the most easily.
Using these easily during the Portable electric equipment, all must be dependent on battery and supply required electric power.In at present all battery varieties, should belong to power supplying efficiency the best of lithium battery.The consumer is for the requirement of battery, can require all usually that power-on time is long, efficient is good, power supply is stable, extendibility is good, the storage capacitance is big, even but at present best lithium battery still can't satisfy the demand of user fully.
In the notebook computer that generally uses at present, it only disposes a battery usually, so battery-powered time just is subjected to the quantitative limitation of battery storage electric capacity itself.When not having external power supply unit to supply, the user must prepare many battery back ups.But essential again shutdown earlier when changing battery can be carried out separating of battery and change operation, so will cause the interruption of work, influences operating efficiency.
Moreover the user is when using notebook computer to carry out some work, and the character of this work may not allow power breakdown or executive program interrupts (for example making monitoring, data operation ...).In this type of use occasion, if battery electric quantity exhausts, user's battery of promptly having to change has so promptly interrupted the execution of whole work.
And for battery producer or notebook computer manufacturer, for disappearance that will overcome aforementioned located by prior art and the demand that satisfies the user, the former product kenel that has the dealer to make so-called main battery (MainBattery), second battery (Second Battery) is for user person's use of needs.But when reality is used, and can't reach real simplicity of operation and expandability, and this practice has increased the stock control trouble of battery manufacturer and notebook computer manufacturer on foot and make the program of producing complicated.
In view of the disappearance of aforementioned each located by prior art, be necessary to be improved in fact, with the capacity of lifting supply of electric power and the extendibility of electric power at the battery expandability and the simplicity of operation of this Portable electric equipment.
Summary of the invention
Therefore, main purpose of the present invention provides a kind of open-ended battery pack, and in order to provide the Portable electric equipment bigger power supply capacity, the user can be required according to reality, and selects the quantity of battery combination.
Another object of the present invention provides a kind of battery component of pegging graft and expanding, its by easy connected structure with combination that plural at least battery is pegged graft, to supply the Portable electric equipment required longer power-on time.
Another purpose of the present invention provides a kind of battery pack that can peg graft immediately and expand, when it can be about to use up at the battery electric quantity of original Portable electric equipment institute standard configuration, expand the instant parallel operation of battery with another, to continue supply electric power to this Portable electric equipment, with the loss of avoiding being caused because of power breakdown.
The present invention is in conjunction with a connector and a socket in extendible battery component for the technological means that problem adopted that solves known techniques, wherein this connector can be plugged to the power input of a portable electronic apparatus, and this socket can be pegged graft for the connector of another extendible battery component.In this extendible battery component, has a battery link circuit, in order to connect the battery cell in this extendible battery component, and this battery cell is connected to this connector and socket respectively, so that the connector of this extendible battery component when being plugged to the power input of portable electronic apparatus, is supplied electric power to this portable electronic apparatus jointly by the extendible battery component of each grafting.
Can be provided with the battery protection unit in this battery component, in order to protect the battery cell in this extendible battery component.This battery component also can be provided with the battery preventing mechanism, avoid each battery component when the grafting parallel operation, produce the phenomenon of higher voltage batteries assembly to the battery component discharge of low voltage because of each battery component voltage is different, this battery preventing mechanism can be a comparison circuit or other equivalent circuit.
Via above-mentioned design of the present invention, can realize portability, the extendibility of additional battery, and the user is when expanding electric power, do not need notebook computer is shut down, do not need yet with battery by the battery case seat in separated, can reach rapidly, easily that battery electric power expands and the function of common supply electric power.And for battery producer or notebook computer manufacturer, do not need to make so-called main battery, second battery yet, can use different combinations and reach the effect that battery electric power expands at same battery component.And each extendible battery component of the present invention all has the connector and the socket of same size, so also can simplify the stock control of battery manufacturer and the program that simplification produces.
Above-mentioned and other purpose and structure design characteristic and advantage of the present invention will be further described by following preferred embodiment and accompanying drawing.
