The switchable charger of the present invention has the advantages of reliable location, convenient operation and low cost and meets the requirement of environmental protection.
Description
Relevant a kind of battery charger of the present invention and charging method thereof.
Battery is the device that chemical energy is converted to electric energy, contaminative is little in the use owing to electric energy, convert the energy efficiency height of other patterns to, so can be considered a kind of portability power supply (PowerSource), therefore generally receive an acclaim, used computer, clock, calling set, walkman, electric razor, flashlight, camera etc. all need to provide power supply by battery in the daily life.General commonly used dry cell, for example mercury battery and alkaline battery, owing to contain harmful heavy metal, the dry cell of discarding has become serious environmental issue.
In view of this, developed at present and a kind of rechargeable battery, it can reuse via recharging, to meet environmental protection standard and economic interests.Common rechargeable battery comprises nickel-cadmium cell, Ni-MH battery, lead accumulator and lithium battery.
In general charging process, owing to battery temperature increased and to improve along with the charging interval, can produce the phenomenon that battery liquid leaks, in addition, overcharging also can exert an adverse impact to battery.For fear of the problems referred to above; the simplest method is when uncharged or charging is pulled out the plug of battery charger when acquiring a certain degree; but this method is inconvenience quite; therefore, adopt at present mostly and reach predeterminated voltage value and/or preset charged time can stop automatically charging method with the protection battery.
Battery commonly used is divided into four classes according to the size difference usually, and the standard model is AAA, AA, C and D, and its length and diameter are followed successively by from big to small: D type, C type, AA type and AAA type.For meeting the market requirement; the rechargeable battery of several identical/different sizes is charged; developed at present and a kind of battery charger assembly with array charhing unit; it is pre-set battery capacity section size (length and width are all different); charge with rechargeable battery to various models; with the battery charger that can charge to four rechargeable batteries simultaneously at most is example; just need design and comprise four AAA; three AAA and an AA; two AAA and two AA; the style of AAA and three AA and four five kinds of battery chargers such as AA; select for the consumer; certainly; if consider the variation of rechargeable battery number and kind; then the style of battery charger must be more, and this does not quite meet economic benefit and does not meet environmental protection requirement.In addition, must have different designs at the battery capacity section size of the rechargeable battery of different types charging, and the distance of both positive and negative polarity contact zone is also inequality, so the external form of entire cell charger assembly is quite not attractive in appearance.
For overcoming above-mentioned shortcoming, make the battery capacity section of battery charger assembly be single specification, developed at present a kind of adjustable type formula battery charger that utilizes telescopic spring adjustment to meet the rechargeable battery size, Fig. 1 (a), Fig. 1 (b) are traditional stereogram that utilizes the battery charger of the adjustable type formula that the telescopic spring adjustment meets the rechargeable battery size, and the structure of this charger comprises a body 11,12, one anodal contact zone 13, a battery capacity section, an adjusting lever 14.Under normal circumstances, adjusting lever 14 is positioned the position near anodal contact zone 13 under spring 16 tension, just can hold AAA type rechargeable battery and charge; If desire is charged to AA type rechargeable battery, then need form the situation shown in Fig. 1 (b), after the AA type battery that again desire is charged this moment is put into battery capacity section 12 with adjusting lever 14 toward drawing back away from the direction of anodal contact zone 13, can form path, charge.Though the method can reach simultaneously the effect that the battery to AAA and two kinds of different models of AA charges, but, its shortcoming is: (one) is positioned on the battery capacity section 12 in order to make the AAA type under normal condition, so that charge, spring 16 must have enough pulling force, and excessive pulling force causes when AA type rechargeable battery is charged, and must apply very big strength and just can draw back adjusting lever 14, so quite inconvenient; (2) after this kind charger uses between long-term, the problem of spring 16 elastic fatigues takes place easily, can influence so backward AAA type rechargeable battery is charged, because spring 16 just is difficult for making AAA type rechargeable battery to be fixed on the battery capacity section 12 because of after elastic fatigue loses the part pulling force.
