导电件12可以设置于供电座壳体11的表面或者凸出于供电座壳体11的表面,以方便导电部与导电件12之间的连接和分离。
在一实施方式中,如图1所示,在安装供电座壳体11时,可以使得导电件12的上方不受到供电座壳体11的遮挡,如此,导电部可以以上下移动的方式实现与导电件12的连接和分离,使得供电座1与受电头2的导通和断开更为简单方便。
举例而言,如图8所示,该供电座1可以与一受电头2配合。如图6所示,该受电头2可以包括受电头壳体21和导电部22;其中,受电头壳体21用于设于供电座1上方,导电部22设于受电头壳体21,能够在重力作用下与供电座1上的导电件12连接。如此,当受电头壳体21在重力的作用下带动导电部22向下移动时,导电部22可以移动至与导电件12接触连接;此时控制组件14可以检测到该受电头2并控制开关元件13导通,供电座1向受电头2供电。当受电头壳体21受到向上的拉力而向上移动时,导电部22将在受电头壳体21带动下向上移动而与导电件12分离,使得供电座1和受电头2分离;此时,控制组件14控制开关元件13断开,使得供电座1断电。
导电件12可以呈条形、片形、螺旋丝形或者其他形状,以能够与导电部22有效接触为准,本公开对此不做特殊的限定。
导电件12的数量为可以一个或者多个,每个导电件12分别与一个外部电源5的供电路连接。在一实施方式中,导电件12的数量为一个,受电头2上的导电部22的数量也对应的为一个。在另一实施方式中,如图1所示,导电件12的数量为两个且相互绝缘;同样的,受电头2上的导电部22的数量也为两个且相互绝缘,且两个导电件12和两个导电部22能够一一对应连接。
开关元件13用于在控制组件14的控制下导通或者断开,其中,开关元件13的输入端用于与外部电源5连接。在一实施方式中,开关元件13可以为继电器。继电器既可以为机械式继电器,例如电磁继电器或者磁簧继电器,也可以为固态继电器,还可以是其他类型的继电器。在另一实施方式中,开关元件13可以为半导体开关。半导体开关可以为三极管、绝缘栅双极型晶体管或者其他半导体开关。
控制组件14可以包括检测器件和控制电路142,检测器件连接控制电路142的输入端,控制电路142的输出端连接开关元件13的控制端。其中,检测器件用于检测受电头2并将检测结果发送给控制电路142,控制电路142根据所接收到的检测结果控制开关元件13导通或者关闭。检测器件的数量可以为一个,也可以为多个。当检测器件的数量为多个时,多个检测器件的类型可以相同或者不同,本公开对此不做特殊的限定。
举例而言,在一实施方式中,控制组件14可以包括控制电路142和作为检测器件的光检测器141,其中,光检测器141用于在接收到受电头2发出的检测光线时输出第一检测信号,且用于在未接收到受电头2发出的检测光线时输出第二检测信号。控制电路142连接光检测器141的输出端和开关元件13的控制端,用于根据第一检测信号控制开关元件13导通,且根据第二检测信号控制开关元件13断开。如此,该控制组件14可以通过检测检测光线的方式来检测受电头2。相较于检测受电头2对环境光线的遮挡来检测受电头2的方案,本公开的方案既克服了对环境光线的依赖,又克服了意外遮挡环境光线而导致供电座1通电的危险。
可以理解的是,与该供电座1配合的受电头2需要具有发出检测光线的功能。如图6所示,受电头2还可以包括发光器23,发光器23设于受电头壳体21,用于发出能够被光检测器141接收的检测光线。发光器23可以为多种不同的发光器件,以所发出的光线与光检测器141的能够检测的光线相互匹配为准。
在一实施方式中,光检测器141包括红外光接收器,用于接收红外线;对应的,发光器23可以为红外线发射器,用于发出红外线作为检测光线。在另一实施方式中,光检测器141包括激光接收器,用于接收激光;对应的,发光器23可以为激光发射器,用于发出激光作为检测光线。当然的,检测光线还可以为可见光或者其他类型的光线,发光器23对应的设置为能够发出该检测光线的发光装置,光检测器141也对应的设置为能够接收该检测光线的光检测装置,本公开对此不做特殊的限定。
光检测器141可以包括光电元件,用于将检测光线的光信号转化为电信号。当受电头2发出的检测光线照射到光电元件时,光电元件将产生检测电流或者检测电压,使得光检测器141发出第一检测信号;当光电元件未被受电头发出的检测光线照射时,光电元件将不产生检测电流或者检测电压,使得光检测器142发出第二检测信号。光电元件 可以包括光敏电阻、PIN光电二极管或者其他光电元件,本公开对此不做特殊的限定。
可选地,如图1所示,控制组件14还可以包括磁体143,磁体143设于供电座壳体11,用于产生一磁场,磁场能够被受电头2响应并使得受电头2发出检测光线。磁体143可以为磁铁、电磁铁或者其他能够产生磁场的装置,本公开对此不做特殊的限定。
可以理解的是,与该供电座1配合的受电头2需要具有响应磁场并在检测到磁场时发出检测光线的功能。如图6和7所示,受电头2还可以包括磁场检测器24,磁场检测器24设于受电头壳体21并与发光器23连接,用于在检测到磁体143产生的磁场时控制发光器23发光,且用于在未检测到磁体143产生的磁场时控制发光器23不发光。如此,在受电头2远离供电座1时,磁场检测器24不能检测到磁体143发出的磁场,因此发光器23不发光,达到降低功耗且延长发光器23的使用寿命的作用。当受电头2靠近供电座1时,磁场检测器24检测到磁体143的磁场后可以控制发光器23发光,保证了发光器23可以及时提供检测光线。
在一实施方式中,磁场检测器24在检测到的磁场大于设定值时向发光器23发出发光信号,发光器23响应发光信号而发光;磁场检测器24在检测到的磁场不大于设定值时,不向发光器23发出发光信号,发光器23不能收到发光信号而不发光。磁场检测器24可以包括磁开关、霍尔传感器或者其他能够检测磁场的器件,本公开对此不做特殊的限定。
再举例而言,在另一实施方式中,如图1和图4(未显示开关元件)所示,控制组件14可以包括控制电路142和作为检测器件的限位开关(limit switch)144,限位开关144设于供电座壳体11,用于在检测到受电头2时输出第三检测信号,且在未检测到受电头2时输出第四检测信号。控制电路142连接限位开关144的输出端和开关元件13的控制端,用于根据第三检测信号控制开关元件13导通,且用于根据第四检测信号控制开关元件13断开。
限位开关144可以为接触式限位开关。举例而言,限位开关144可以包括触头和开关电路,且开关电路上设置有微动开关(Micro Switch),触头与微动开关连接。当受电头2运动至与触头接触时,触头将使得微动开关导通,使得开关电路发出第三检测信号;当受电头与触头不接触时,微动开关将保持断开状态,使得开关电路发出第四检测信号。当然的,限位开关144也可以为非接触式限位开关,例如可以为干簧管式限位开关、光电式限位开关、感应式限位开关或者其他类型的限位开关,本公开对此不做特殊的限定。
再举例而言,在另一实施方式中,控制组件14可以包括控制电路142、作为检测器件的光检测器141和作为检测器件的限位开关144。光检测器141用于在接收到受电头2发出的检测光线时输出第一检测信号,且用于在未接收到受电头2发出的检测光线时输 出第二检测信号。限位开关144设于供电座壳体11,用于在检测到受电头2时输出第三检测信号,且在未检测到受电头2时输出第四检测信号。控制电路142的输入端连接光检测器141的输出端和限位开关144的输出端,控制电路142的输出端连接开关元件13的控制端。控制电路142用于根据第一检测信号和第三检测信号控制开关元件13的导通,根据第二检测信号和第四检测信号控制开关元件13的断开。
控制电路142可以在接收到第一检测信号和第三检测信号时控制开关元件13导通,在其他条件下控制开关元件13断开。如此,开关元件13的导通需要满足两个控制条件,即光检测器141检测到检测光线、限位开关144检测到受电头2;如此,可以避免环境中的光线或者意外按压限位开关144而引起供电座1导通,进一步提高供电座1的安全性。
在更进一步地方案中,如图2所示,控制电路142可以包括一与门电路1421,与门电路1421的第一输入端用于接收第一检测信号或第二检测信号,与门电路1421的第二输入端用于接收第三检测信号或第四检测信号,与门电路1421的输出端与开关元件13的控制端连接;与门电路1421用于在同时接收到第一检测信号和第三检测信号时,控制开关元件13导通。
举例而言,第一检测信号和第三检测信号可以为高电平(逻辑1),第二信号和第四信号可以为低电平(逻辑0),如此,只有与门电路1421的两个输入端均为1时,才输出高电平控制信号(逻辑1),否则输出低电平控制信号(逻辑0)。高电平控制信号(逻辑1)用于控制开关元件13导通,低电平控制信号(逻辑0)用于控制开关元件13断开。控制电路142无需采用MCU(微控制单元)、CPU(中央处理器)、FPGA(现场可编程门阵列)或者SOC(系统级芯片)等控制器,其电路结构简单且降低了供电座1的成本。
可以理解的是,本公开提供了具有不同检测器件的实施方式,即:检测器件为光检测器141和限位开关144的组合、检测器件为光检测器141和检测器件为限位开关144。上述实施方式仅仅是为了解释和说明检测器件和控制组件14而做出的示例,检测器件还可以为其他类型的检测器件,例如还可以为磁场检测器、超声波检测器,也可以为多种不同类型的器件的组合,以能够实现对受电头的检测为准。
在一实施方式中,如图1和图5所示,供电座壳体11可以具有供电座槽110,供电座槽110用于受电头2的插入;光检测器141、导电件12和限位开关144设于供电座槽110内,在供电座壳体11的保护下更不容易损毁。不仅如此,照射到光检测器141上的环境光线会更少或更弱,降低了光检测器141因环境光线而输出第一控制信号可能性。限位开关144不会凸出于供电座壳体11的外轮廓,不容易被外物意外按压而输出第三控 制信号。导电件12也不会凸出于供电座壳体11的外轮廓,使得外物更不容易触碰导电件12而产生触电风险。因此,供电座1的安全性进一步提高。
在一实施方式中,如图3所示,供电座槽110为梯形槽,其中,槽口的尺寸大于槽底111。在安装供电座1时,如图8所示,可以使得供电座1的槽口向上且供电座1的槽底111在下,如此,受电头2可以在重力作用下插入供电槽内。
在一实施方式中,如图3所示,供电座槽110可以包括槽口、与槽口相对设置的槽底111、以及连接槽口和槽底111的侧壁112。供电座槽110还包括一开放侧面,该开放侧面与槽口、侧壁112和槽底111连接,且该开放侧面能够允许受电头2以与供电座槽110配合的姿态至少部分进入该供电座槽110内。在另一实施方式中,当受电头2配合地插入供电座槽110内时,受电头2插入供电座槽110的部分在开放侧面所在平面上的正投影,位于该开放侧面以内。在安装时,可以使得槽口向上,开放侧面水平向外。如此,该供电座槽110包括槽口和开放侧面两个可供受电头2进入的开口,可以使得受电头2与供电座槽110的配合过程更为灵活。
在一实施方式中,如图3和图4所示,光检测器141设置于供电座槽110的侧壁112。如此,检测光线需要沿垂直于或者接近垂直于受电头2插入的方向才能射入光检测器141,使得光检测器141可以更好地定位受电头2的插入深度。更进一步地,供电座1的侧壁112数量为多个,光检测器141设置于与开放侧面相对设置的侧壁112上。
可以理解的是,与该供电座1相配合的受电头壳体21能够至少部分插入供电座槽110;如图6所示,且受电头壳体21具有与设置光检测器141的供电座槽110的侧壁112相配合的配合表面211;发光器23设置于配合表面211,以使得发光器23发出的检测光线能够照射到光检测器141上。
在一实施方式中,如图1所示,磁体143设于供电座壳体11内且位于供电座槽110的下方。如此,磁体143设置于受电头2插入供电座槽110的方向上,磁场检测器24所检测到的磁场的强度随受电头2插入供电座槽110的深度增加而增加,提高了磁场检测器24根据磁场控制发光器23发光的稳定性,提高了供电座1供电的稳定性。对应的,如图6所示,受电头2上具有与槽底111配合的端面212,磁场检测器24靠近端面212设置。
在一实施方式中,如图5所示,导电件12设于限位开关144,且当供电座1与受电头2配合时,导电件12位于限位开关144与受电头2之间。举例而言,导电件12设于限位开关144的触头上。如此,受电头2通过导电部22和导电件12向限位开关144传导压力,以保证当限位开关144开启时,导电部22与导电件12之间呈压紧状态。当导电部22和导电件12之间因未压紧而接触不良时,受电头2不能有效按压限位开关144, 使得限位开关144不导通,保证该供电座1处于断电状态,避免了导电部22和导电件12在接触不良的情况下导电而引起的危险。
当然的,导电件12也可以设置于其他位置,例如直接或间接设置于供电座壳体11,以实现能够与受电头2的导电部22连接为准。
本公开还提供一种受电头2,用于与上述供电座1实施方式所描述的供电座1配合。如图6和图7所示,受电头2包括受电头壳体21和导电部22;导电部22设于受电头壳体21,能够与供电座1上的导电件12连接。
在一实施方式中,受电头壳体21可以设置于供电座1上方,以便能够在重力的作用下向下移动至与供电座1相配合,使得导电部22能够借助受电头壳体21的重力实现与导电件12的连接。当然的,受电头壳体21还可以借助其他力实现向供电座1的移动并与供电座1配合,例如可以借助磁吸力、空气压力等。
在一实施方式中,如图6和图7所示,当供电座1具有光检测器141时,受电头2还包括发光器23,发光器23设于受电头壳体21,用于发出能够被光检测器141接收的检测光线。
在一实施方式中,如图6和图7所示,当供电座1具有磁体143时,受电头2还包括磁场检测器24,磁场检测器24设于受电头壳体21并与发光器23连接,用于在检测到磁体143产生的磁场时控制发光器23发光,且用于在未检测到磁体143产生的磁场时控制发光器23不发光。
在一实施方式中,当供电座1具有限位开关144时,受电头2被配置为能够与限位开关144接触连接,以使得限位开关144可以检测到受电头2。当然的,当限位开关为非接触式限位开光时,受电头2可以被配置为能够移动至限位开关检测范围内,以使得限位开关144能够检测到受电头2。
在一实施方式中,如图6和图7所示,当供电座1具有供电座槽110,且光检测器141设置于供电座槽110的侧壁112时,受电头壳体21能够至少部分插入供电座槽110;且受电头壳体21具有与设置光检测器141的供电座槽110的侧壁112相配合的配合表面211;发光器23设置于配合表面211。
本公开提供的受电头2的具体细节和有益效果,在上述供电座1实施方式中已经进行了详细的描述,本公开在此不再赘述。
本公开还提供了一种供电装置,如图8所示,充电装置包括供电座1、受电头2、导线3和导线收放机构4,其中,
供电座1为上述供电座1实施方式所描述的供电座1;受电头2为上述受电头2实施方式所描述的受电头2;导线3连接受电头2的导电部22;导线收放机构4用于收纳 或者释放导线3,且当释放导线3时,受电头2能够与供电座1接触,使得导电部22与导电件12连接。
如此,当需要供电时,控制导线收放机构4释放导线3,受电头2可以移动至与供电座1配合,供电座1的导电件12与受电头2的导电部22连接;此时,供电座1检测到受电头2,内部的开关元件13导通,使得导线3通过受电头2、供电座1电连接外部电源5。当不需要供电时,控制导线收放机构4收纳导线3,受电头2在导线3的拉力下移动,供电座1的导电件12与受电头2的导电部22分离,导线3与外部电源5之间不连接;此时,导线3可以收纳于导线收放机构4内,避免了裸露在外影响环境布局。
因此,可以通过控制导线收放机构4收纳或者释放导线3,达成控制导线3与外部电源5之间的连接或者断开的目的。本公开的供电装置的供电座1为上述供电座1实施方式所描述的供电座1、受电头2为上述受电头2实施方式所描述的受电头2,因此具有相同的有益效果,本公开对此不做特殊的限制。
在一实施方式中,导线3连接受电头2的导电部22,且能够使得受电头2位于供电座1的上方;当导线收放机构4释放导线3时,受电头2在重力作用下与供电座1接触,使得导电部22与导电件12连接。
在一实施方式中,如图8所示,导线收放机构4可以包括卷线盘和电机,导线3至少部分缠绕于卷线盘上。当电机驱动卷线盘转动时,卷线盘可以收纳或者释放导线3。
该供电装置既可以直接为电视机、显示屏、电子画屏等电子设备供电,也可以为电视机、显示屏、电子画屏等电子设备的电池充电。
在一实施方式中,供电装置用于向电池充电。供电装置还可以包括充电组件、充电检测组件和充电控制组件14,充电组件连接电池和导线3,用于利用外部电源5向电池充电;充电检测组件用于检测电池的电量,并将检测的结果发送至充电控制组件14;充电控制组件14连接充电检测组件和导线收放机构4,用于在电池电量低于第一设定值时释放导线3,使得受电头2与充电座配合,以便外部电源5向电池充电;且充电控制组件14还用于在电池电量高于第二设定值时收纳导线3,使得受电头2与充电座分离,避免电池过度充电。如此,该供电装置能够向电池自动充电。
本公开还提供一种供电方法,应用于上述供电装置。该供电方法包括:
当需要供电时,控制导线收放机构4释放导线3,以使得供电座1的导电件12与受电头2的导电部22连接;
当不需要供电时,控制导线收放机构4收纳导线3,以使得供电座1的导电件12与受电头2的导电部22分离。
本公开提供的供电方法的原理和有益效果在上述供电装置实施方式中已经进行了详 细的描述,本公开在此不再赘述。
本公开还提供一种显示装置,该显示装置包括上述供电装置实施方式所描述的供电装置。该显示装置可以为电子画屏、壁挂式电视机、壁挂式显示器、电子广告牌或者其他显示装置,本公开对此不做特殊的限定。
本公开的显示装置的供电装置与上述供电装置实施方式所描述的供电装置相同,因此具有相同的有益效果,本公开在此不再赘述。
本公开还提供一种画屏,如图9和图10所示,该画屏包括显示面板6和上述供电装置实施方式所描述的供电装置,其中,显示面板6具有出光面,且供电装置的导线收放机构4设置于显示面板6远离出光面的一侧。如此,导线收放机构4设置于显示面板6的后方,其被显示面板6遮挡而不影响画屏的布局,避免了导线收放机构4遮挡显示面板6而降低画屏的显示效果和外观。本公开的画屏的供电装置与上述供电装置实施方式所描述的供电装置相同,因此具有相同的有益效果,本公开在此不再赘述。
在一实施方式中,如图9和图10所示,当导线收放机构4收纳导线3后,受电头2在导线3的拉力作用下移动至靠近导线收放机构4的位置,且导线收放机构4和受电头2在显示面板6的正投影在显示面板6内。如此,当供电装置不向显示面板6供电时,显示面板6可以完全遮挡导线收放机构4、导线3和受电头2,避免了导线收放机构4、导线3或受电头2等影响画屏的安装效果。
在一实施方式中,如图10所示,该画屏可以通过连接件8以挂壁的方式安装于支撑壁7上。该连接件8可以为挂架、紧固螺栓或者其他可行的连接组件;该支撑壁7可以为墙壁、橱柜侧壁、屏风或则其他可以用于支撑画屏的结构。当画屏挂接于支撑壁7上时,供电座1可以设置于支撑壁7上且位于导线收放机构4的下方,以使得受电头2能够在重力作用下向供电座1移动并最终与供电座1配合。
在一实施方式中,画屏还包括外壳,显示面板6可以设置于外壳内,导线收放机构4可以设置于外壳外。可选的,当画屏固定于支撑壁7时,沿水平方向,导线收放机构4位于外壳的中心或者靠近外壳的中心,以提高画屏的稳定性。
