技术领域
这是2003年10月14日提交的专利申请No.10/685,280的部分连续申请。
本发明基本涉及便携式音频和电池组充电装置。
背景技术
没有电线的(cordless)电动工具经常发现并用在那些不具有方便获得或方便的电源的场合。这些场合包括建筑工地和部分完成的建筑物。在例如这些的场合中,电池操作的工具提供了显而易见的优点,但是电池组最终被耗尽,并且需要被再充电。而一些用户带着足够数目的电池组以持续一整天,在建筑的某些阶段,通常至少提供临时的电力服务,这使得电池组能够在建筑工地被再充电。临时电力服务的位置可能距离实际工作位置有一定距离,并且因为充电器可能距离用户有一定距离,因此会产生问题,这可能阻止充电操作成功完成。例如,另一个工人可能取走电池组用于自己使用,或者充电器可能简单地被拔下,从而可以进行一些其它操作,因为可利用的容座的数目受到限制。
工人还喜欢将音频设备例如便携式收音机带到建筑工地,从而当他们工作时可以听着音乐和其它节目。众所周知,对于这些随着时间由于显而易见的原因容易受损的音频设备来说,建筑工地的环境是恶劣的。
发明内容
公开了音频电源装置的优选实施例,该装置提供音频输出,并且对可拆的电池组进行充电,并且提供多个AC容座用于当装置连接到AC电源时驱动其它工具。该装置可选地提供DC电能。当装置连接到AC电源时,AC电源驱动音频装置,该音频装置可以是收音机或者组合收音机和CD播放器,并且AC电源还向充电器供电,如果电池组插入充电器的容座中,充电器对电池组进行再充电。当电池组放置在充电器容座中时,如果该装置没有连接到AC电源,收音机可以由电池组驱动。当装置连接到AC电源时,继电器被打开以使收音机装置与充电器和电池组隔离。其它的实施例可包括一个或多个另外的音频和视频装置,例如卫星收音机、数字音频播放器、DVD播放器、VCD播放器和电视机。
该装置具有独特的保护框架结构,该结构连接到装置的壳体。本发明的优选实施例还具有一电路,该电路包括继电器,继电器适用于当继电器线圈检测到AC电源被施加到音频装置时将电池组和充电器从音频装置隔离。如果没有检测到AC电源,继电器闭合,从而电池组可以驱动音频装置。

具体实施方式
对音频装置充电的便携式电池的优选实施例在附图中示出,并且其包括壳体,壳体通常以10示出,壳体是立方体的形式,但如果需要它也可以是长方体以及一些其它成形体积形状。如图所示,它包括前表面或前壁12、左侧表面或壁14、顶面16、后壁20(见图4)和右侧表面或壁22。壳体10优选由坚韧的塑料或者其它模制材料制成,并且可包括多个或数个部件,所述部件结构上一起配合在结实坚固的装置中。例如,前壁和后壁12和20可以是基本平坦的整体件,所述整体件共同连接到一个或多个模制的或者用其它方法形成的前壁、顶壁、底壁和后壁,所述壁可以形成为一个、两个或多个部件,所述部件利用六角形端头螺栓或螺杆24连接在一起。虽然壳体10是立方体的形状,即每个壁的尺寸基本相同,但是壳体也可以是长方体,其中,长度、高度和宽度尺寸中的一个或多个可以比其它的大,即矩形盒状的形状,或者更不常见的体积形状可以由壳体的壁限定。
优选实施例具有音频装置,该装置通常以30示出,音频装置设置在装置的前表面12中。如图1和图2清楚所示,音频装置包括收音机,收音机具有控制面板32,面板32具有音量控制装置34、调谐控制装置36、显示装置38,显示装置用于显示电台标识和当前时间。具有时间调节按钮40、42和44,其中按钮42控制小时设置,并且按钮44控制分钟设置。CD播放器同样设置作为装置30的一部分,并且CD托盘46定位在控制面板32上方。分别具有位于控制面板32上的弹出按钮48、停止或者等待(standby)按钮50、以及前进和后退调节按钮52和54。同样设置了扬声器56、58、60和62,位于控制面板32的下面。
该装置可以利用电线70连接或者插在AC电源中,所述电线70具有三脚插头72,如图6清楚所示。该装置具有电线卷绕结构,该结构包括四个向外延伸的凸缘74,凸缘74设置成正方形,电线可以卷绕在正方形周围用于存储。凸缘均具有用于安装到侧壁14的基部76,并且通过螺杆78等连接到其处。还应当理解,如果需要,凸缘74可以整体形成在侧壁14中。用于待描述的电路的保险丝80可在左侧壁14上接近(accessible),DC容座(receptacle)或者插座(socket)82也一样,插座82受到可拆的柔性插塞的保护以防止外部环境(elements),所述插塞优选由可以插入容座开口中的橡胶或者类似材料制成。两通道立体声小型插头容座83设置在保险丝30附近,其可以用于输入辅助音频源,所述辅助音频源可以通过所述装置进行播放。容座83因此连接到音频装置30,如图9所示。同样,铭牌85通过四个螺杆安装到左侧壁14,所述螺杆包括两个顶部螺杆87。辅助音频源在容座83中的存在可以被检测,并且从而可以被选择作为播放的来源,或者转换装置87可以设置在面板32上,用于选择集成的音频装置、或者连接到辅助容座的装置。
所述装置具有内部设置在壳体中的充电器84,充电器84可通过充电器门86接近,如图4所示。手柄88设置在它的上端处,其接合互补的表面以保持所述门闭合,但是它可以由用户毫无困难地方便开启。门的下端上的绞接件90使得门可以被开启以露出保持腔92,腔92具有位于腔92的底部处的容座94,如图5所示。容座94的结构是互补的以接纳电池组,电池组例如由Robert BoschTool Corporation所销售的那些。多个弹簧卡子96同样被设置以当电池组在充电时将电池组保持在适合的位置,充电要求电线78被连接到AC电源。
在右侧壁16上,并且参考图7,一对二重(duplex)AC插座100设置在门102的下面(仅示出了其中一个),其绞接在插座对的顶部处。虽然它们可以是标准二重插座,但优选的是它们是接地故障电路断路器,从而为用户提供额外的安全措施,特别是在给定装置可能受到恶劣天气状况影响的事实的情况下。作为对于接地故障电路断路器的标准,复位按钮104和检测按钮106被设置。
为了方便携带所述装置,并且参考图8,装置18的顶面具有手柄108,手柄108由基本半球形的凹部110形成,凹部110具有跨接部分112,跨接部分延伸过所述凹部,并且共同限定可用于携带所述装置的手柄108。显然,凹部的尺寸可以足够大从而用户可以将他的手方便地插入凹部中从而抓住所述跨接部分112。
从附图可清楚看出,所述装置具有通常以120表示的框架结构,框架结构实际上在所有附图中示出,但是在图2、图4和图8中最为清楚。框架结构120沿着每个方向都比壳体10大,并且从而为壳体本身以及位于壳体的前表面、后表面和侧表面中的每一个上的部件提供保护结构。在优选实施例中,框架结构20的形式是表面开(open faced)的立方体,但是如果需要也可以是表面开口的长方体。框架结构具有多个伸长的柱形杆122,所述杆122优选由中空的铝制成。所述杆相对于每两个壁的交界处以间隔的关系延伸,如图清楚所示。在形成在框架结构120的八个拐角中的每一个处的三个壁的交界处,三个柱形杆122在三通连接器124中终止,连接器124优选由坚固的、坚硬的塑料或者能够承受苛刻处理同时不会造成损害的塑料状材料制成。如图2和图4清楚所示,连接器中的每一个具有一对定位螺杆126,螺杆126配合在连接器124中的开口内,并且沿着水平或者竖直方向接合柱形杆122的侧部,如图所示,并且具有六角形端头的螺杆128,螺杆128被设置成接合杆122,杆122沿着横向于水平和竖直方向的方向定向,如图2和图4所示。定位螺杆128可以接合中空杆122的内径,或者它可以接合被这种横向插入所述柱形杆122的每一端中的插塞或者其它元件,从而实现了连接器到所述杆的固定连接。关于螺杆126,它们可以仅仅被收紧紧靠它们接触在其中的杆的外表面,或者它们可以被拧到杆的侧部中。
如图1和图8清楚所示,壳体具有伸长的凹部130,凹部130位于壳体的顶部和侧部的拐角处、以及壳体的底部和侧部的拐角处。优选具有相同结构和外径的较短的柱形杆132配合在每个凹部内,并且通过配合到壳体中的相对应尺寸的开口中从而被固定在相反的端部处。框架结构120通过连杆134连接到这些杆132,连杆134具有位于相反端部中的开口,杆122和132可穿过所述开口。具有位于每个凹部130的端部处的连杆134,这意味着它们中的全部八个被用于将框架结构120固定到壳体12。连杆134优选由与连接器124相同的材料制成,从而它们将不会被通常粗暴的处理容易地破坏,在建筑工地,该装置可能会受到所述处理。
关于体现本发明的装置的电路示意图,并且参考图9,音频装置30被示为通过保险丝80和线路140、142连接到电线70。接地线144同样从插座100延伸到插头72。线路140和142同样延伸到插座100,并且延伸到充电器84,其中充电器84具有输出线146和148,输出线146和148延伸到容座94,可拆的电池可以插入所述容座94中。线路146和148还延伸到继电器150,继电器150由继电器线圈152控制,线圈152检测电流是否在线路140和142中流动。继电器150是通常闭合的继电器,当插头72连接到AC电源时所述继电器断开,这意味着音频装置由AC电源驱动。应当理解,音频装置实际上可以在DC电压上工作,并且音频装置可具有内部电压转换器作为它的结构的一部分。
另一个转换器154可以被设置以向DC插口82供电。当插头72连接到AC电源时,如果电池被放置在容座94中,充电器84被操作以使可拆的电池充电,并且插座100可用于向其它工具、灯等供电,DC插座82也一样。如果插头72从AC电源移开,继电器150将电路闭合,从而可拆的电池将连接到音频装置,并且可以驱动音频装置。应当理解,当如图所示继电器电路打开时,充电器不能够驱动音频装置,并且当AC电源没有被施加到电路时,充电器不能够驱动音频装置30,因为充电器84不具有通过线路140和142的AC电源以外的固有电池或其它电源。
虽然上述实施例包括音频装置30,其中音频装置30包括收音机,并且还建议了收音机和CD播放器的组合,但是其它的音频以及视频源也可以结合在装置中。
在图10所示的第二实施例中,通常示出为160的便携式数字音频播放器被示为安装到侧壁14。虽然由于它容纳在外壳162中的原因它在这个附图中根本看不到,其中外壳162具有窗口164和开口166,窗口164用于观察这种播放器的显示装置,开口166优选包括透明柔性膜,所述膜用于限制灰尘和水进入外壳的内部。所示的外壳160特别设计用于与数字音频播放器一起使用。这种数字音频播放器可播放多种格式,例如MP3、WMA或者AAC音频格式。它们可以是专用的数字音频播放器,或者也可以是其它类型的装置,例如PDA或者蜂窝电话,它们具有内置的这种功能。它们可使用各种类型的介质,例如硬盘驱动器、闪存、或者可拆的磁盘介质。如图10到图16所示,外壳162具有基部168和盖子部分170,其中基部和盖子通过绞接件172和闭锁机构174彼此连接。闭锁机构具有钩子176,钩子176接合保持表面(未示出),其中闭锁机构176可在盖子中的槽中滑动,从而将盖子锁定到基部168和将盖子从基部168松开。
数字音频播放器160具有连接器(未示出),所述连接器构造成:当数字音频播放器放置在由底部表面180和弯曲的侧表面182限定的摇篮状(cradle)结构中时,与基部168中的第二连接器178相互连接。数字音频播放器以不同的模型被销售,模型具有不同的数据存储能力,并且它们的厚度可以相应改变。因此,多个柔性弹性垫可以与外壳162一起设置,包括所示的垫184。垫184可以放置在外壳中,从而数字音频播放器被适合地与它对齐,从而它的连接器将配合在连接器178中,并且被保持在适合的位置,以防止例如如果装置10被推挤或者落下它被破坏。在这方面,可以构想,将有多个不同厚度的垫184,从而使用者可以插入或者连接适合的一个以将它支撑在基部168中。在这方面,优选的是每个垫具有粘附的垫底,所述垫底被薄膜覆盖,所述薄膜可以被移去,从而所述垫可以连接到基部168的内表面。
如图12清楚所示,基部168的后部具有基本柱形的电源插头,该插头被构造成配合在如图6所示的12伏适配器82中,用于向数字音频播放器供电。在这方面,具有内部电路(未示出),所述内部电路与具有连接器178的电源插头连接,从而电能被提供给数字音频播放器。类似的,2通道立体声微型插头188同样被设置成配合在图6所示的微型插头容座83中,并且这也与连接器178相互连接,从而数字音频播放信号可以被传送到图9所示的音频装置30中的放大器,使得放大器能够根据需要驱动扬声器60和62。应当理解,拨动开关可以设置在面板32上,该开关选择无线电接收器或者来自微型插头容座83的输入。如图16清楚所示,在每一端上具有孔192的支架190被设置,并且通过下面的方式连接到侧壁14:将螺杆87移开,并且放置覆盖铭牌的支架,并且之后重新设置螺杆87以将支架190安装到侧壁。在这方面,支架具有较厚的外周,所述外周限定凹部193,并且开口194设置在支架190的中部,开口194构造成接纳闭锁元件196,元件196构造成插入孔194中以将其锁住。
如图12、14和16所示,闭锁件196形成为伸长的滑动翼片198的一部分,滑动翼片198配合在凹部200内,凹部200优选形成在基部168中,并且它还优选是闭锁件196的一部分。滑动翼片198的一端202向外延伸到凹部200的端部外,并且可用于被向内推动,从而闭锁件196可以脱离孔194,并且使得外壳162能够被从侧壁14移开。滑动翼片198的结构在图15中示出为具有相反的端部,所述端部具有基本蜿蜒形(serpentine)并且优选为S形的较薄的部分204,部分204位于滑动翼片的主要部分和端部206之间,其中S形部分204限定弹性件,用于将闭锁件196朝着它的锁定位置偏压,如图16所示。在这方面,优选的是滑动翼片198由ABS或者能够提供所需的弹性或者偏压力的其它略微柔性的材料制成。应当理解,滑动翼片的尺寸使得端部206必须与凹部200的端部接触,并且从而被加载使得当它安装在外壳162中时偏压力通常施加到闭锁件196。
本发明的另一个实施例在图17和18中示出,其中,卫星无线电接收器210被示出,并且构造成使得它具有底部连接器,所述底部连接器接合与图14的连接器178类似的连接器。在这种结构中,外壳是基部212的形式,基部212与基部168类似,但是其不具有前部盖子,并且因此没有被完全封闭。因为卫星接收器210优选是整体的产品,该产品可以从装置10移开,从而它可以连接到用户的机动车辆中类似的支架,例如,用于操作收音机的控制装置包含在收音机装置本身中,除了可能的外部音量控制装置,该音量控制装置与音频装置30中的放大器相连。还可以考虑并且落在本发明范围内的是卫星无线电装置可以仅是设置在装置10中的音频接收器。
又另一个实施例在图19中示出,其中装置具有音频和视频播放器,该播放器通常以214示出,播放器设置在装置的前表面12中。使用那些与图2的实施例中使用和描述的附图标记相同的附图标记,其中功能基本类似。播放器包括视频显示装置216和调谐控制装置36,显示装置216是具有音量控制装置34的控制面板32的一部分。CD播放器、DVD播放器和/或VCD播放器可以被设置,并且托盘46定位在控制面板32的上方。应当理解,显示装置216也可以是TV接收器的一部分。还具有分别位于控制面板32上的弹出按钮48、停止或者等待按钮50、以及前进和后退调节按钮52、54。还应当理解,这个实施例可以构造成接收来自便携式音频和视频源例如便携式DVD播放器或其它视频源的音频和视频信号,并且显示装置216然后可以与便携式播放器一起使用。
虽然已经示出和描述了本发明的各种实施例,但是应当理解,对于本领域的普通技术人员来说,其它修改、替换和可替换方案是显而易见的。在不脱离本发明实质和范围的情况下,可以做出这些修改、替换和可替换方案,这些应当根据所附的权利要求确定。
