交叉引用
本申请要求在2022年07月27日提交中国专利局、申请号为202210889089.6、名称为“无线充电座及无线充电装置”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请属于通信技术领域，具体涉及一种无线充电座及无线充电装置。
背景技术
伴随充电技术的发展，为提高电子设备充电的便利性，无线充电器应运而生。无线充电器无需电源线，依靠电磁波形式即可对电子设备实现无线充电。
由于无线充电器的线圈需与电子设备的线圈实现通信连接才可实现充电，故电子设备相对无线充电器的位置要求较高，基于此，相关技术中的无线充电器利用磁吸作用力吸附电子设备，来保证电子设备准确处于充电位。然而，电子设备充电完成后，在磁吸作用下，电子设备无法直接脱离无线充电座，用户需手动分离电子设备和无线充电器，导致操作不便。
发明内容
本申请实施例的目的是提供一种无线充电座及无线充电装置，能够解决相关技术中手动分离无线充电器和电子设备导致操作不便的问题。
第一方面，本申请实施例提供一种无线充电座，包括设备主体、电磁线圈、动作开关和承压件，所述电磁线圈和所述承压件均设于所述设备主体，所述承压件可相对于所述设备主体在第一位置和第二位置之间运动，所述动作开关的至少部分与所述承压件相连，以跟随所述承压件运动，且所述动作开关用于控制所述电磁线圈通电或断电；在所述承压件处于所述第一位置的 情况下，所述动作开关电导通，以使所述电磁线圈处于通电状态；在所述承压件处于所述第二位置的情况下，所述动作开关电断开，以使所述电磁线圈处于断电状态。
第二方面，本申请实施例提供一种无线充电装置，包括电子设备和上述的无线充电座，所述无线充电座用于给所述电子设备充电；在所述电子设备放置于所述承压件上时，所述承压件处于所述第一位置；在所述电子设备远离所述承压件时，所述承压件从所述第一位置移动至所述第二位置。
在本申请实施例中，在需要对电子设备充电时，电子设备直接放置在承压件上，承压件处于受压状态，承压件相对设备主体运动至第一位置，动作开关的至少部分跟随承压件运动，此时动作开关电导通，以使电磁线圈通电并产生磁吸力，通过磁吸力对电子设备进行吸附，保持电子设备与无线充电座的相对位置固定，有利于电子设备准确处于充电位，保证充电过程的有效进行。在充电完成后，用户手动拿取电子设备，拿取过程中手动作用力克服电子设备的重力，即承压件由受压状态切换至未受压状态，承压件运动至第二位置，动作开关也跟随承压件运动，此时动作开关电断开，以使电磁线圈断电，磁吸力消失，电子设备不会再被吸附，电子设备和无线充电座直接分离开，故无需再施加较大的作用力来分离无线充电座和电子设备，简化操作过程，操作更加方便，而且，用户的体验感提升。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的无线充电座及无线充电装置进行详细地说明。
参考图1-图8，本申请实施例公开一种无线充电座，所公开的无线充电座包括设备主体100、电磁线圈200、动作开关600和承压件300。其中，设备主体100作为电磁线圈200和承压件300的安装基础，电磁线圈200和承 压件300均设于设备主体100，在电磁线圈200通电的情况下，电磁线圈200产生磁吸力，无线充电座可吸附电子设备。
承压件300相对于设备主体100可运动，且动作开关600的至少部分与承压件300相连，故动作开关600的至少部分跟随承压件300运动，利用动作开关600的至少部分的运动可切换电磁线圈200的状态。具体来说，承压件300相对于设备主体100在第一位置和第二位置之间运动，承压件300可以相对于设备主体100转动，动作开关600的至少部分可以跟随承压件300转动；承压件300也可以相对于设备主体100移动，动作开关600的至少部分可以跟随承压件300移动。可选地，动作开关600的一部分可以与承压件300相连，动作开关600的另一部分可以相对于设备主体100固定，承压件300运动时带动动作开关600的一部分运动；承压件300可以与动作开关600的整体相连，承压件300运动时带动动作开关600的整体运动。总之，承压件300运动时带动动作开关600的至少部分运动，以使动作开关600在电导通状态和电断开状态之间切换，进而使电磁线圈200在通电状态和断电状态之间切换。
在承压件300处于第一位置的情况下，动作开关600电导通，以使电磁线圈200处于通电状态；在承压件300处于第二位置的情况下，动作开关600电断开，以使电磁线圈200处于断电状态。在本实施例中，在承压件300处于第一位置的情况下，说明承压件300承受电子设备对其的压力，此时动作开关600电导通，电磁线圈200通电以产生磁吸力，无线充电座能够吸附电子设备，保持电子设备与无线充电座的相对位置固定，有利于电子准确处于充电位，保证充电过程的有效进行。在承压件300处于第二位置的情况下，说明承压件300未承受电子设备对其的压力，具体来说，电子设备充电完成后，用户拿取电子设备的过程中，手动作用力逐渐克服电子设备的重力，使得承压件300由受压状态切换至未受压状态，承压件300离开第一位置并运动至第二位置，动作开关600也切换至电断开状态，此时电磁线圈200处于断电状态，且磁吸力消失，电子设备不会再被吸附，故电子设备和无线充电座可直接分离开，无需再手动施加较大的作用力来分离无线充电座和电子设备，简化操作过程，无线充电座的使用更加方便，而且，用户的体验感提升。
在可选的实施例中，电磁线圈200为磁吸附线圈，无线充电座还包括充电线圈，充电线圈与电磁线圈200同时通电或断电，在充电线圈处于通电状 态的情况下，无线充电座对电子设备充电，此时，充电和吸附电子设备由不同的线圈实现，并且充电线圈的状态可随电磁线圈200的状态发生变化，从而在不需要充电时断开充电线圈，以此降低无线充电座的能耗。在另一可选的实施例中，电磁线圈200为充电线圈。如此，承压件300运动的过程中切换电磁线圈200的状态，不仅能够控制无线充电座是否吸附电子设备，还能控制无线充电座是否对电子设备充电，避免电子设备与无线充电座分离而电磁线圈200持续工作的情况，减小无线充电座的能耗，节省能源。
一种可选的实施例中，结合图2-图4所示，电磁线圈200设有断口211，以使电磁线圈200具有第一端212和第二端213，即电磁线圈200为非闭合线圈，动作开关600位于第一端212和第二端213之间，且动作开关600的整体跟随承压件300运动。在承压件300位于第一位置的情况下，动作开关600导通电磁线圈200的第一端212和第二端213，以使电磁线圈200处于通电状态；在承压件300位于第二位置的情况下，动作开关600与电磁线圈200分离，以使电磁线圈200处于断电状态。在本实施例中，无线充电座还包括通电线，通电线与电磁线圈200电连接，且通电线用于电连接供电设备，该供电设备可以为固定电源或移动电源。
动作开关600具有第三端和第四端，在承压件300位于第一位置的情况下，动作开关600的第三端和第四端分别与电磁线圈200的第一端212和第二端213相连，电磁线圈200和动作开关600形成闭合线圈，由于电磁线圈200持续通电，故此时闭合线圈处于通电状态，电磁线圈200能够产生磁吸力，无线充电座可吸附电子设备，同时，无线充电座对电子设备充电。在承压件300位于第二位置的情况下，动作开关600和电磁线圈200分离，此时动作开关600和电磁线圈200无法形成闭合线圈，即电磁线圈200无法通电，电磁线圈200也无法产生电磁场，电磁线圈200无法吸附电子设备。
采用本实施例，承压件300仅需带动动作开关600运动，无需带动电磁线圈200的整体运动来切换电磁线圈200的状态，因此，承压件300较易在第一位置和第二位置之间切换，比较灵敏地切换电磁线圈200的状态。
在承压件300位于第一位置的情况下，由于动作开关600的第三端与电磁线圈200的第一端212、动作开关600的第四端与电磁线圈200的第二端213之间的接触面积较小，有可能导致电磁线圈200与动作开关600无法准确形成闭合线圈。故，在一种实施例中，电磁线圈200的第一端212设有第一 金属片410，电磁线圈200的第二端213设有第二金属片420，动作开关600具有第三端和第四端，动作开关600的第三端设有第三金属片430，动作开关600的第四端设有第四金属片440。第一金属片410和第二金属片420可以向动作开关600所在位置延伸，从而便于连接动作开关600；第三金属片430可以向电磁线圈200的第一端212延伸，第四金属片440也可以向电磁线圈200的第二端213延伸，从而便于连接动作开关600。
在承压件300位于第一位置的情况下，第一金属片410与第三金属片430接触，第二金属片420与第四金属片440接触，此时，动作开关600的第三端通过第一金属片410和第三金属片430与电磁线圈200的第一端212连接，动作开关600的第四端通过第二金属片420和第四金属片440与电磁线圈200的第二端213连接，从而使电磁线圈200、第一金属片410、第三金属片430、动作开关600、第四金属片440、第二金属片420共同形成闭合线圈，电磁线圈200处于通电状态；如图4所示，在承压件300位于第二位置的情况下，第一金属片410与第三金属片430分离，第二金属片420与第四金属片440分离。具体地，第一金属片410和第三金属片430可以叠置，第一金属片410的顶面或底面可与第三金属片430的底面或顶面贴合接触；第二金属片420和第四金属片440可以叠置，以使第二金属片420的顶面或底面与第四金属片440的底面或顶面贴合接触。如此，第一金属片410与第三金属片430之间的接触面积较大，第二金属片420与第四金属片440的接触面积也较大，使得电磁线圈200的第一端212和第二端213能够与动作开关600准确连接而形成闭合线圈。
另一种可选的实施例中，动作开关600具有接触端610，无线充电座还包括电路板500，电路板500用于对电磁线圈200供电，电路板500与设备主体100相连。可选地，电路板500可以设置于承压件300，电路板500以及动作开关600的至少部分共同跟随承压件300运动，即电路板500与设备主体100间接相连；电路板500也可以设置于设备主体100，即电路板500与设备主体直接相连。在动作开关600的至少部分沿第一方向运动的情况下，接触端610被按压，动作开关600被触发，动作开关600控制电磁线圈200与电路板500之间电导通，电磁线圈200处于通电状态；在动作开关600的至少部分沿第二方向运动的情况下，接触端610被释放，动作开关600控制电磁线圈200与电路板500之间电断开，电磁线圈200处于断电状态。其中， 第一方向和第二方向相反。可选地，动作开关600的接触端610可以被设备主体100按压，也可以被承压件300或电路板500按压。
采用本实施例，在承压件300运动的过程中，动作开关600的接触端610被按压或被释放，进而实现动作开关600的电导通或电断开，从而实现对电磁线圈200状态的切换。
一种可选的实施例中，设备主体100包括壳体110，动作开关600可以设置于壳体110，在承压件300位于第一位置的情况下，承压件300按压动作开关600的接触端610，动作开关600被触发，动作开关600控制电路板500与电磁线圈200之间电导通，电磁线圈200处于通电状态；在承压件300位于第二位置的情况下，承压件300与动作开关600的接触端610之间具有间隙，动作开关600处于未触发状态，动作开关600控制电路板500与电磁线圈200之间电断开，电磁线圈200处于断电状态。
另一种可选的实施例中，动作开关600设置于承压件300，动作开关600的整体可跟随承压件300运动，接触端610可与壳体110的内壁面接触，如图7所示，在承压件300位于第一位置的情况下，壳体110的内壁面按压动作开关600的接触端610，动作开关600被触发，动作开关600控制电路板500与电磁线圈200之间电导通；如图6所示，在承压件300位于第二位置的情况下，动作开关600的接触端610与壳体110的内壁面之间具有间隙，动作开关600处于未触发状态，动作开关600控制电路板500与电磁线圈200之间电断开。可选地，动作开关600可以为接触开关。
采用本实施例，承压件300在运动过程中对动作开关600的状态进行控制，进而动作开关600控制电磁线圈200是否处于通电状态，故电磁线圈200不需要设置成具有断口211的非闭合线圈，其电导通时的可靠性更高。
在可选的实施例中，承压件300包括相连的第一承压板310和第二承压板320，第二承压板320的至少部分设于壳体110之内，且第二承压板320与壳体110滑动连接。可选地，第二承压板320包括第一环状部322，第一环状部322伸入壳体110之内，且第一环状部322的外壁面与壳体110的内壁面滑动接触。第一承压板310和第二承压板320共同形成第一容纳空间330，电磁线圈200、电路板500和动作开关600依次设于第一容纳空间330内，且第二承压板320开设有用于供动作开关600的接触端610伸出至第一容纳空间330之外的开孔a，开孔a与壳体110的内壁面相对。此情况下，承压件 300与电磁线圈200的整体相连。
可选地，第二承压板320还包括主体板321和第二环状部323，第一环状部322和第二环状部323分别设于主体板321的两侧，且主体板321位于壳体110之内，第二环状部323伸出至壳体110之外，主体板321和第二环状部323形成第一容纳槽，第一承压板310盖在第二环状部323的端口，故主体板321、第二环状部323和第一承压板310共同形成第一容纳空间330。如图6和图7所示，主体板321的中部为弯折结构，以使主体板321的中部形成用于容纳动作开关600的第二凹槽。
在本实施例中，第一承压板310和第二承压板320相卡接，以使二者之间可拆卸地相连。实际应用时，先将电磁线圈200、电路板500和动作开关600依次连接，再将三者组成的整体结构安装于第一容纳槽内，最后将第一承压板310盖在第一容纳槽的槽口处。
第一承压板310和第二承压板320带动电磁线圈200、电路板500和动作开关600一起运动，有利于电磁线圈200、电路板500和动作开关600的整体装配，避免三者分散设置而导致连接困难的情况；而且，电磁线圈200、电路板500和动作开关600在第一容纳空间330内依次接触，避免在电磁线圈200和电路板500之间、电路板500与动作开关600之间设置线路，有利于简化无线充电座的结构。
在可选的实施例中，壳体110包括第一壳部101和第二壳部102，第一壳部101和第二壳部102相卡接，以使二者之间可拆卸地相连，第二承压板320伸入第二壳部102内，且第二承压板320与第二壳部102滑动接触。实际应用时，首先将第二承压板320安装于第二壳部102，然后将电磁线圈200、电路板500和动作开关600安装于第一容纳槽内，再将第一承压板310盖在第一容纳槽的槽口处，并将第一壳部101与第二壳部102卡接。
为保证承压件300能够顺利由第一位置回复至第二位置，无线充电座还包括弹性件700，弹性件700的一端与设备主体100相连，弹性件700的另一端与承压件300相连。在承压件300处于第一位置的情况下，弹性件700发生弹性形变；在承压件300处于第二位置的情况下，弹性件700恢复弹性形变。在电子设备按压承压件300的过程中，承压件300沿第二位置至第一位置的方向运动，弹性件700发生弹性形变，直至承压件300运动至第一位置，弹性件700作用于承压件300的弹性作用力与电子设备对承压件300的 按压作用力相等；在按压作用力逐渐减小的过程中，弹性作用力大于按压作用力，弹性件700驱动承压件300反向运动，直至承压件300复位至第二位置。其中，弹性件700可以为弹簧。
利用弹性件700，能够使未受压的承压件300由第一位置复位至第二位置，进而使承压件300在第一位置和第二位置之间切换，保证电磁线圈200在通电状态和断电状态之间顺利切换。
一种可选的实施例中，如图4和图5所示，弹性件700的数量可以为一个；或者，如图6和图7所示，弹性件700的数量为多个，各弹性件700间隔分布于承压件300和设备主体100之间，在本实施例中，多个弹性件700环绕动作开关600的接触端610设置。可选地，在承压件300与动作开关600的一部分相连的情况下，弹性件700可以为一个；在承压件300与动作开关600的整体相连的情况下，弹性件700可以设置为多个。如此，多个弹性件700分别对承压件300施加弹性作用力，即承压件300的多个位置均承受弹性作用力，承压件300受力更加均匀，有利于承压件300稳定地由第一位置切换至第二位置。
在可选的实施例中，如图1-图3所示，设备主体100包括壳体110，壳体110包括支撑底壁111、环形侧壁112以及弯折部113，支撑底壁111与环形侧壁112相连，且支撑底壁111设有安装孔130，承压件300活动设置于安装孔130处，支撑底壁111和环形侧壁112共同形成第二容纳槽120，电磁线圈200、弹性件700和弯折部113均设置在第二容纳槽120内，且弯折部113的一端与支撑底壁111相连，弯折部113的另一端与弹性件700相连，利用弯折部113，方便固定弹性件700的一端。在本实施例中，电磁线圈200环绕承压件300、弹性件700和弯折部113设置，充分利用第二容纳槽120的空间，提高空间利用率，有利于减小无线充电座的占用空间。可选地，支撑底壁111、环形侧壁112和弯折部113可以为一体成型结构。
一种可选的实施例中，如图6和图7所示，设备主体100包括壳体110，壳体110设有安装孔130，承压件300设于安装孔130处，且承压件300具有第一承载面311，第一承载面311用于支撑电子设备，壳体110位于承压件300背离第一承载面311的一侧。可选地，沿垂直于第一承载面311的方向，第一承载面311的正投影可以覆盖壳体110的正投影，即第一承载面311的面积较大，第一承载面311足够单独支撑电子设备。在本实施例中，第 一承压板310设有第一承载面311，第二承压板320设于安装孔130处，且第二承压板320的第二环状部323的外壁面与安装孔130的孔壁滑动接触。采用本实施例，由于壳体110位于承压件300背离第一承载面311的一侧，故第一承载面311能够始终单独支撑电子设备，使承压件300能够准确承受电子设备对其的作用力，保证承压件300及时运动。
另一种可选的实施例中，如图4和图5所示，承压件300具有第一承载面311，设备主体100包括壳体110，壳体110的外壁面包括第二承载面140，第二承载面140设有安装孔130，安装孔130与第二容纳槽120相连通，承压件300设于安装孔130处。如图5所示，在承压件300位于第一位置的情况下，第一承载面311与第二承载面140相平齐，此时第一承载面311和第二承载面140共同支撑电子设备，避免承压件300受压过大导致承压件300运动过度；在承压件300位于第二位置的情况下，第一承载面311凸出于第二承载面140，此时承压件300能够准确承受电子设备对其的作用力，保证承压件300能够及时运动。
在本申请的方案中，如图4和图5所示，无线充电座还包括锁止件810和锁止槽820，锁止件810与设备主体100活动连接，锁止槽820开设于承压件300，锁止件810可伸入锁止槽820内，以使承压件300保持于第一位置。可选地，设备主体100包括壳体110，锁止件810可以与壳体110转动连接，锁止件810也可以与壳体110滑动连接，总之，锁止件810在运动过程中能够伸入锁止槽820即可。在用户携带或移动无线充电座和电子设备的过程中，电子设备的重力可能不会作用于承压件300，此时为保证电磁线圈200通电，利用锁止件810伸入锁止槽820，使承压件300持续位于第一位置，进而保证无线充电座顺利对电子设备充电，扩展无线充电座的应用场景。
在可选的实施例中，如图1所示，设备主体100包括壳体110，锁止件810设置于壳体110的内壁面，或者，壳体110的外表面设有第一凹槽150，锁止件810裸露设置于第一凹槽150内。在本实施例中，第一凹槽150设置于壳体110的第二承载面140。如此，用户可直接手动伸入第一凹槽150内并对锁止件810进行操作，方便实现承压件300的锁止或解锁。
一种可选的实施例中，设备主体100包括壳体110，承压件300的至少部分设于壳体110之内，壳体110和承压件300中的一者设有限位槽920，另一者设有限位凸起910，限位凸起910伸入限位槽920内，且限位槽920 设有相对的第一限位面921和第二限位面922，限位凸起910设有相背的第三限位面911和第四限位面912，第一限位面921可与第三限位面911限位配合，第二限位面922可与第四限位面912限位配合。
可选地，如图4和图5所示，限位槽920设置于承压件300，限位凸起910设置于壳体110，在承压件300位于第一位置的情况下，第一限位面921与第三限位面911接触；在承压件300位于第二位置的情况下，第二限位面922与第四限位面912接触。可选地，如图6和图7所示，第二承压板320的部分为限位凸起910，壳体110的内壁面形成限位槽920，其中，第二承压板320的主体板321背向第一环状部322的一侧为第三限位面911，壳体110的内壁面朝向第三限位面911的一侧为第四限位面912，在承压件300位于第二位置的情况下，第三限位面911与第四限位面912限位接触，即主体板321与壳体110的内壁面限位接触。
通过限位槽920和限位凸起910，限制承压件300的运动行程，避免承压件300运动距离过大，保证承压件300能够准确位于第一位置或第二位置。
基于本申请公开的无线充电座，本申请实施例还公开一种无线充电装置，所公开的无线充电装置包括电子设备以及上述实施例中的无线充电座，无线充电座用于给电子设备充电。在电子设备放置于承压件300上时，承压件300处于第一位置；在电子设备远离承压件300时，承压件300从第一位置移动至第二位置。具体地，在电子设备放置于承压件300上时，电子设备对承压件300施加作用力，承压件300受压并运动至第一位置；在电子设备远离承压件300时，承压件300不再受压，承压件300可复位至第一位置。
如此，该无线充电装置的承压件300通过带动动作开关600的至少部分运动，进而实现动作开关600的电导通和电断开，最终使电磁线圈200在通电状态和断电状态之间切换。过程中无需手动施加作用力来分离无线充电座和电子设备，简化操作过程，无线充电座的使用更加方便。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
