一种锂电池及充电宝 技术领域
本发明涉及可充电电池领域,具体涉及一种锂电池及充电宝。
背景技术
现有通用圆柱电池,主要指输出电压为1.5V的5号和7号电池,此外,还包括1号、2号等均为酸性或碱性的电池;对于外形尺寸和通用的圆柱电池相同的圆柱锂电池来说,由于锂电池具有含量高、放电电压稳定、可多次反复充电、环保节能灯优越性能,将逐渐取代现有的普通碱性或酸性电池,被人们应用到现有通用圆柱电池的使用领域。
由于锂电池的充电电压和放电电压均在3.7V以上,而通用圆柱电池的充放电压均为1.5V左右,因此,目前的圆柱锂电池如果要取代普通酸性或碱性电池,不仅外形要与普通酸性或碱性电池相同,而且放电电压要达到稳定的1.5V;因而,锂电池需要在电池内设置充电电路载体和放电电路载体,以解决自身充电和给用电设备放电的问题。
现有的关于这种特质的充电装置分为两类:
一类是外置充电盒,这类圆柱锂电池仅仅是把充电电路装置放入与外置充电盒内,而占用电池容积的充电电路载体和放电电路载体仍放置于圆柱锂电池内,该类圆柱锂电池充电麻烦、增添了圆柱锂电池使用成本,充电盒还存在容易丢失的情况;
另一类圆柱锂电池自身带充电USB插头或充电Micro USB插座、即Micro USB母座。其中自带充电USB插头的圆柱锂电池,如中国申请号为200580040272.3的专利公开的可再充电电池组件,虽充电时不需专用外置充电器,但其USB插头套装在圆柱锂电池的套盖内部,结构复杂,而且在充电时,还需要抽开套盖,以露出USB插头,采用该充电结构的圆柱锂电池,不仅充电不便,同时还占用了圆柱锂电池大量有效地空间、圆柱锂电池的电容 量减少三分之一以上;另外,自带充电Micro USB插座的圆柱锂电池,还需通过外接Micro USB公头的充电线进行充电,此外,该类内置Micro USB插座和充、放电电路的圆柱锂电池同样需要占用圆柱锂电池的大量有效空间,从而降低了锂电池的电容量;不仅如此,现有的手机充电宝锂电池,一般均内置有至少一个用于输出电量的USB插座和至少一个用于输入电量的Micro USB插座,不仅占用了充电宝的容积,而且必须通过充电线才能给自身或给手机充电,使用和携带均不便。
USB插座又称为USB母座,包括USB框壳和USB舌板,两者之间的位置相对固定,通常两者通过铆接固定成一整体;其中,USB框壳由金属板材制成,USB舌板由塑胶板和金属接电弹条制成,金属接电弹条固设于塑胶板上。

实施例2至6,于实施例1的基础上,USB舌板3可通过以下实施方式与内端盖4滑动连接。
实施方式一,如图1和图2所示,USB舌板3还包括轴突6,轴突6位于靠近USB舌板3根部端的反向两侧;内端盖4的顶部还包括导槽7,导槽7的对向两侧还包括限位槽8, USB舌板3设于导槽7内,导槽7与USB舌板3相配合,轴突6位于限位槽8内,限位槽8与轴突6相配合,以使USB舌板3与内端盖4滑动连接。滑止结构通过轴突6位于限位槽8内,起到限位作用,以防止USB舌板3滑出内端盖4。
实施方式二,如图3-4或图5-6所示,内端盖4的顶部还包括导槽7,导槽7的对向两侧与USB舌板3的反向两侧还包括凸起部9和限位滑槽10,导槽7与USB舌板3相配合,凸起部9与限位滑槽10相配合,以使USB舌板与内端盖滑动连接。凸起部9可以为凸柱状,优选为凸板状。滑止结构可以通过USB舌板3与内端盖4处通过上述所示的轴突6与限位槽8相配合的结构进行限位,也可以通过USB舌板3和内端盖4分别采用阶梯槽与阶梯块配合结构进行限位,还可以通过如图8所示的凸起部13与限位滑槽14相配合的结构进行限位,以防止USB舌板3滑出内端盖4。
实施方式三,如图9-12所示,内端盖4的顶部还包括燕尾凸轨11,USB舌板3的底部还包括燕尾滑槽12,燕尾凸轨11的背向两侧与燕尾滑槽12的对向两侧还包括凸起部13和限位滑槽14,燕尾凸轨11与燕尾滑槽12相配合,凸起部13与限位滑槽14相配合,以使USB舌板与内端盖滑动连接。滑止结构可以通过凸起部13与限位滑槽14相配合,还可以通过采用阶梯形燕尾凸轨11和阶梯形燕尾滑槽12相配合,以防止USB舌板3滑出内端盖4。
如图13所示,USB舌板3与外部的USB插座插接时,USB舌板3与设于金属边框17内的USB母座舌板18配合,正、负极导电条16与USB母座舌板18上的导电条19对接,以对锂电芯充电。
本发明锂电池USB舌板与PCB板的充电电路连接方式可通过下述方式实现:
优选方式一,如图1至图6和图8至图12所示,USB舌板3的底部和内端盖4的顶部分别设有正、负极导电条16、15,内端盖4的正、负极导电条15与PCB板37的充电电路连接,当USB舌板3滑出内端盖4的表面,USB舌板3的正、负极导电条16与内端盖4的正、负极导电条15接触,以连接充电电路。导电条15、16优选为弹性材料。
优选方式二,上述内端盖4的导电条15变换为如图7所示的弹性充电触点151。
方式三,上述内端盖4的导电条15的电路延伸到如图1和图2所示的限位槽8内,相应的,USB舌板3的导电条16的电路延伸到轴突6处;或者,如图7所示,正、负极导电条16的根部延伸形成导电圆弧状,使得当USB舌板3滑出后通过轴突6转动时,USB舌板3的正、负极导电条16与内端盖4的正、负极导电条15始终接触,该结构能够实现USB舌板3的滑动加转动,USB舌板更灵活,占用空间小,适用范围广,使用方便。
上述锂电池还可以作形状及尺寸等适当变换,增设放电接口,而能够起到实质等同于充电宝的作用,因此,上述锂电池的实施范围并不受电池范围的限制。本发明的充电宝基于上述USB舌板滑动连接利于节省空间,结构简单而且使用方便的特点,进一步专门针对于作为充电宝实施时进行的改进,详述如下。
如图14和图15所示,一种充电宝,包括锂电芯20、壳体21、USB舌板3和PCB板37;锂电芯20和PCB板37装设于壳体21内,壳体21设有充放电开口51,金属框壳22固设于充放电开口51内,USB舌板3容置于USB框壳22内,USB舌板3还与接电滑块24连接,接电滑块24还包括拨扭25,壳体21内还包括滑槽26,滑槽26的一端与充放电开口51连通,滑槽26的顶部还包括导槽27,导槽27贯设于壳体21上,USB舌板3和接电滑块24位于滑槽26内,拨扭25伸出于壳体21外并限位滑动于导槽27,带动USB舌板3伸出缩回USB框壳22;使用时,USB舌板3通过拨扭25从充放电开口51滑出,USB舌板3通过导接线28和接电滑块24与PCB板37的充电电路连接,以与外部的USB插座插接,以对锂电芯20充电。其电路连接方式可参考上述锂电池连接方式。
优选还包括导接线28,导接线28位于滑槽26内,USB舌板3通过导接线28与接电滑块24连接或导接线28直接与充放电路连接(参考图20)。导接线28优选为具有一定柔性带状的,可金属导电条或由塑料包封的金属导电条制成,具有一定柔性和弹性,以利于使用和插接。使用时,通过拨动拨扭25,推动USB舌板3以及导接线28滑出充放电开口51。 滑槽26利于导接线28的限位滑移,利于接电滑块24与触点的准确接触。
滑槽26优选还包括USB内腔29,USB内腔29位于邻接充放电开口51处,当USB舌板3滑入壳体内,USB舌板3位于USB框壳22内的USB内腔29处,以形成USB插座。通过能伸缩的USB舌板3的设置,用一个单一充放电接口方案替换现有技术的充电、放电接口单独设置方案,且内置收纳空间,无需外部数据线与充电宝搭配使用,占用空间小,结构简单,而且使用方便。
上述充电宝的电路连接可通过USB舌板3、导接线28以及接电滑块24上设有正、负极电路23,滑槽26设有充电触点30和放电触点31,充电触点30与PCB板37的充电电路连接,放电触点31与PCB板37的放电电路连接,当USB舌板3滑出USB内腔29,USB舌板3通过接电滑块24与充电触点30接触,以使正、负极电路23与充电电路连接;当USB舌板3滑入USB内腔29,USB舌板3通过接电滑块24与放电触点31接触,以使正、负极电路23与放电电路连接。
本发明的USB舌板3优选为USB导电舌板式。
采用滑移的结构,使得USB舌板的位置移动更易操作,相对于只能转动连接的USB舌板来说,滑移设置的USB舌板由于不需要借助很大的外力就可改变位移,操作便捷,因此可有效保证其使用寿命,不易损坏。
USB舌板滑设于USB框壳22内的USB内腔29处;USB舌板3上设有接电弹条和侧边凸起弹条;USB舌板3通过伸缩出入USB内腔29实现充电宝USB舌板3充电功能和放电功能的转换,结构简单,效果可靠。
将在锂电池中可滑动伸缩的USB舌板3应用在充电宝中,USB舌板3在滑动的过程中,通过装设于其上接电滑块与正极输入触点或负极输出触点连接,进而改变USB舌板3的功能;USB舌板3伸出即为公头,可从其他充电设备的USB插座中取电,USB舌板3缩回至USB框壳22内的USB内腔29则为USB插座,可以通过插入USB充电数据线为手机充电,充电 和放电状态的切换便捷、可靠。
基于本发明的上述构思,上述充电宝的USB舌板3还可以进一步改进变换为放电插头,此时不需要通过外部USB充电数据线,而直接为手机等相应接口设备充电。该方式可基于上述充电宝的基础上实施,详述如下:
一种充电宝,如图16所示,包括锂电芯20、壳体21和PCB板37;锂电芯20和PCB板37装设于壳体21内,壳体21设有第二开口,即放电开口33,还包括放电插头32,放电插头32包括正、负极导电条,放电插头32可为Micro USB插头、Lightning插头和USB Type-C插头中的一种或几种。
放电插头32位于壳体21内,放电插头32还与接电滑块24连接,其连接可以为直接连接,优选通过导接线28式间接连接。导接线28包括正、负极导电条,导接线28位于滑槽26内,此时,通过拨动拨扭25,推动放电插头32以及导接线28滑出充电开口。
接电滑块24还包括拨扭25,壳体21内还包括滑槽26,滑槽26的一端与放电开口33连通,滑槽26的顶部还包括导槽27,导槽27贯设于壳体21上,放电插头32和接电滑块24位于滑槽26内,拨扭25于导槽27处伸出,以使放电插头32与壳体21滑动连接;
使用时,放电插头32通过拨扭25从放电开口33滑出,放电插头32通过接电滑块24与PCB板37的放电电路连接,以对具有相应接口的设备充电。其电路连接方式可参考上述实施方式,如通过在导槽27设置放电触点31,当放电插头32滑出放电开口33,放电插头32通过接电滑块24与放电触点31接触,以使放电插头32的正、负极导电条与放电电路连接。
该充电宝完全不需外接充、放电数据线,可以给自身充电,也可以给手机充电,滑槽的设置利于收纳和保护充、放电装置,极大方便了手机用户的使用。
基于本发明的上述构思,在上述充电宝实施例的基础上进一步改进,以使上述充电宝的USB舌板3和/或放电插头32的位置可被限位,以方便使用,例如USB舌板3和/或放电 插头32的位置可被锁定或解锁。具体实施时,以USB舌板3为例,如图17所示,本实施例的充电宝的USB舌板3的尾端沿USB舌板3的长度方向被延长,USB舌板3尾端的顶部设有卡槽303;本实施例的充电宝还包括有机械半自锁装置的锁组件,本实施例的充电宝的壳体还设有用于容置锁组件的容腔38。
具体地,锁组件包括锁舌40、压缩弹簧39、锁匙41、拉伸的弹簧42和压缩弹簧43,其中,锁舌40被容腔38横向限位并可沿垂直于USB舌板3的竖直方向上、下运动,容腔38的底部于USB舌板3尾端的正上方开有通口,压缩弹簧39被横向限位于容腔38内,以用于弹出锁舌40,该通口的位置优选为当USB舌板3与USB内腔29、金属框壳22一起形成USB插座时对应卡槽303处,如此,使得锁舌40伸出通口时伸入卡槽303,进而锁定USB舌板3的位置。
锁匙41被容腔38竖向限位并可沿平行于USB舌板3的横向方向前、后移动,容腔38的顶部于锁匙41的顶部处开有拨口,锁匙41的顶部从该拨口伸出,弹簧42被容腔38竖向限位,其一端与锁匙41的后端勾接,以用于在向后拉动锁匙41,锁匙41的前端具有锐角结构,并穿经锁舌40的中部,当向前拨动锁匙41,锁匙41通过其前端上部的斜坡面逐渐推动锁舌40向上运动,锁舌40的底端从卡槽303离开,进而使USB舌板3的位置被解锁,由于压缩弹簧43套设于导接线28外并被竖向限位,且其前端顶抵USB舌板3、后端相对壳体固定,使得USB舌板3的头部可在压缩弹簧43的弹力作用下从USB内腔29弹出,用手夹住USB舌板3的头部向外拉出USB舌板3和导接线28,即可将USB舌板3插入外部的USB插座为充电宝充电。
当USB舌板3的位置被锁定、外部USB插头插入该USB插座时,其相互之间的电路连接更可靠;当设置机械半自锁装置和压缩弹簧43时,可不再设置上述充电宝实施例中的拨扭25和导槽27。
作为USB舌板3的一种优选实施方式,还包括接电弹条301和/或凸起弹条302,接电 弹条301设于USB舌板3的顶面,以用于电路连接,其弹性特性可使电路连接的更可靠;USB舌板3的两侧设有凸起弹条302,优选具有弹性金属弹条,凸起弹条302的设置利于插接时各部件的稳固,进一步利于电路连接的稳固可靠。
同样还以USB舌板3为例,如图18所示,其与图17示例的充电宝的不同之处在于,将上述的锁组件的压缩弹簧39、锁舌40、锁匙41和弹簧42变换为以包括压缩弹簧47、锁杆48和固定轴49的方式实施。具体地,继续参阅图18所示,锁杆48于壳体的容腔内与固定轴49可转动连接,锁杆48的一端具有帽状结构并从壳体的表面伸出,压缩弹簧47设于锁杆48和壳体之间,并通过锁杆48的帽状结构固定,以用于复位锁杆48,锁杆48的另一端作为锁舌与USB舌板3的卡槽303相配合。使用时,通过按压锁杆48的一端而控制锁杆48的另一端从卡槽303内退出,进而解锁USB舌板3的位置,此时,USB舌板3在压缩弹簧43的作用下而从USB内腔29弹出,手夹住拉动USB舌板3即可一并将导接线28拉出,进而可插入外部USB插座对充电宝进行充电;收纳时,将导接线28和USB舌板3推回壳体内,如此,USB舌板3可重新卡入卡槽303而锁定USB舌板3的位置。
以放电插头32为例进行实施时,可参考上述以USB舌板3为例的实施例进行实施,一并参考图19所示,放电插头32的尾端设有卡槽320,卡槽320所起作用与上述卡槽303的作用相同,与上述锁组件相配合实施,即可使放电插头32的位置被锁定或解锁,在此不再赘述。
本发明充电宝的USB舌板与充电电路或放电电路的切换,除了可通过上述接电滑块24滑动切换充放电电路方式实现时,还可以通过图20所示方式实现,其与上述充电宝实施例的主要区别在于,将上述接电滑块24的滑接变换为由USB舌板3按压触发的电路切换开关50方式实施。具体地,继续参阅图20所示,电路切换开关50设于PCB板37上的连接电路,并位于壳体内对应容置USB舌板3的尾部处,USB舌板3通过导接线28之间与PCB板37上的连接电路连接。当USB舌板3位于壳体内,其尾部表面按压触发电路切换开关50,如此 实现USB舌板3与放电电路的连接,当USB舌板3位于壳体外,电路切换开关50复位,如此实现USB舌板3与充电电路的连接。该方式在不冲突的情况下,可与前述实施例搭配用于实现USB舌板3伸缩时充放电电路的切换。
需要说明的是,在一些实施例中,在上述充电宝实施例的基础上,放电插头32的位置也可被另一种方式限位,如图21和图22所示,壳体21的表面设有凹槽45,凹槽45的一端设有开口,接电槽44设于凹槽45内相对的两侧面,放电插头32的手持部的侧面向外延伸形成导向翅321,两导向翅321分别伸入接电槽44,放电插头32位于凹槽45内,并可通过导向翅321沿接电槽44延伸方向滑动,相应地,接电滑板46可参考放电插头32的方式实施,也可沿接电槽44延伸方向滑动,不同处在于,接电槽44的导向翅的长度大于导向翅321的长度,以避免接电滑板46滑出,放电插头32通过导接线28与接电滑板46连接,接电滑板46通过其与接电槽44之间的滑动接触面而实现放电电路的连接。
使用时,用手拨动放电插头32,可使放电插头32和导接线28从凹槽45的端部开口伸出,进而可对外部设备充电;收纳时,用手回拨滑动接电滑板46,可收回导接线28和放电插头32。
如图22所示,放电插头32以Micro USB插头、Lightning插头或USB Type-C插头方式实施时,导接线28优选包括负极电源线281、正极电源线282、负极信号线283、正极信号线284和电流显示灯条285,相应地,PCB板上设有IC驱动电路,以用于驱动电流显示灯条285。
具体地,负极信号线283、正极信号线284和电流显示灯条285也可通过接电滑板46与接电槽44之间的滑动接触面而实现与PCB板之间的电路连接。当放电插头32与外部设备连接对外充电时,负极信号线283和正极信号线284将检测到的充电信号发送至PCB板,PCB板根据该信号通过IC驱动电路驱动电流显示灯条285点亮,电流显示灯条285优选以包括LED跑马灯、EL追光线和光纤追光线中的至少一种的方式实施,如此,电流显示灯条 285可通过其发光的方式模拟电流的流动,如可通过追光的方向显示电流的流向,可通过追光闪烁的频率显示充电电流的大小。导接线28实施时优选为包裹有电源线和电流显示灯条的弹性扁线;导接线的包裹层材质优选包括TPU、TPE、PP和硅胶中的至少一种或其任意组合。
需要说明的是,在一些实施例中,上述放电插头32也可变换为上述USB舌板3的方式实施,即将上述包括负极信号线283、正极信号线284和电流显示灯条285的导接线28、包括IC驱动电路的PCB板与上述USB舌板3搭配的方式实施,由于USB舌板3可以充电或放电,因此,当负极信号线283和正极信号线284将检测到的信号发送至PCB板,PCB板根据该信号判断是充电还是放电,并通过IC驱动电路驱动电流显示灯条285点亮,还通过电流显示灯条285的追光方向模拟充电电流或放电电流的流向。
上述说明描述了本发明的优选实施例,但应当理解本发明并非局限于上述实施例,且不应看作对其他实施例的排除。通过本发明的启示,本领域技术人员结合公知或现有技术、知识所进行的改动也应视为在本发明的保护范围内。
