Description

无线充电器 技术领域
本申请涉及电子设备技术领域，具体而言，尤其涉及一种无线充电器。
背景技术
随着电子设备的快速发展及各种应用软件的开发，人们对于电子设备的充电变得更加频繁，传统的有线充电造成充电限制，很不方便。随着无线充电技术的发展和普及，将无线充电技术应用到电子设备的电池充电方面成为趋势。无线充电技术源于无线电能传输技术，可分为小功率无线充电和大功率无线充电两种方式。小功率无线充电常采用电磁感应式，初级线圈具有一定频率的交流电，通过电磁感应在次级线圈中产生一定的电流，从而将能量从传输端转移到接收端。
相关技术中，通过设置无线充电器，利用无线充电器内的线圈与电子设备内线圈形成电磁感应以实现对电子设备的充电。但存在无线充电器体积大，无线充电器与电子设备对不准导致充电效率低、充电操作困难及充电器散热效果差的问题。
申请内容
本申请旨在至少解决现有技术中存在的技术问题之一。为此，本申请提出一种无线充电器，所述无线充电器具有方便操作的优点。
根据本申请实施例的无线充电器，所述无线充电器适于对电子设备充电，所述无线充电器包括：底座组件，所述底座组件具有用于收容电子设备的槽体，所述槽体限定出的空腔的形状与所述电子设备的形状相同；无线充电模块，所述无线充电模块设于底座组件内。
根据本申请实施例的无线充电器，通过设置具有槽体的底座组件，且槽体限定出的空腔的形状与电子设备的形状相同，将电子设备放置在槽体内后，无线充电模块可以对电子设备进行充电，省去了调整电子设备位置的操作，充电方式简单且方便操作。而且无线充电器的设置结构简单且方便携带，尤其是在旅途当中，可以方便用户的使用。

在本申请的描述中，需要理解的是，术语“厚度”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
如图2-图3所示，根据本申请实施例的无线充电器1，包括底座组件10和无线充 电模块20。无线充电器1可以对电子设备充电。
具体而言，如图1-图3及图5所示，底座组件10具有用于收容电子设备的槽体130，槽体130限定出的空腔的形状可以与电子设备的形状相同。无线充电模块20设于底座组件10内。

如图2-图3所示，底座组件10内部可以形成有安装空间100，无线充电模块20可以位于安装空间100内。无线充电模块20可以与底座组件10连接。例如，无线充电模块20可以与底座组件10粘接。无线充电模块20也可以与底座组件10卡接。无线充电模块20还可以与底座组件10通过紧固件(例如螺钉)连接。当然，以上只是给了无线充电模块20与底座组件10连接的一些实施例，无线充电模块20还可以通过其它方式与底座组件10连接，这里不作具体限定。
相关技术中，无线充电器与电子设备的尺寸不对应，无线充电器对电子设备进行充电时，需要花费很多的精力与时间将电子设备与无线充电器对准，且无法确保无线充电器与电子设备对准，往往会导致无线充电器的充电效率明显降低。
根据本申请实施例的无线充电器1，通过设置具有槽体130的底座组件10，且槽体130限定出的空腔的形状与电子设备的形状相同，可以提升电子设备放置的准确率，将电子设备放置在槽体130内后，无线充电模块20可以对电子设备进行充电，省去了调整电子设备位置的操作，充电方式简单且方便操作。而且无线充电器1的设置结构简单且方便携带，尤其是在旅途当中，可以方便用户的使用。
如图2-图3所示，根据本申请的一些实施例，底座组件10的与槽体130的侧壁对应的部分具有导引斜面131，电子设备适于从导引斜面131滑入或滑出。如图2-图3及图5所示，底座组件10的外表面可以形成有导引斜面131，导引斜面131位于槽体130内。导引斜面131可以构造成槽体130的至少部分侧壁面1301。导引斜面131可以导引电子设备滑入槽体130内，导引斜面131也可以导引电子设备从槽体130内滑出。例如，槽体130所对应的侧壁面1301的一部分可以朝向远离槽体130的方向倾斜以形成导引斜面131，导引斜面131与槽体130的底壁1302之间的夹角可以为钝角(即大于九十度且小于一百八十度的角)。
如图2-图3所示，根据本申请的一些实施例，导引斜面131可以与槽体130的底壁1302圆滑过渡。由此，将电子设备放置在槽体130的过程中，可以便于电子设备经过导引斜面131过渡至槽体130内。进一步地，导引斜面131可以形成平面或曲面。无论是平面还是曲面，均具有导引的功能。如图1及图5所示，在本申请的一些实施例中，槽体130内可以设有操作槽140，以为用户提供操作空间。例如，槽体130所对应的侧壁面1301的一部分可以朝向远离槽体130的方向凹陷形成操作槽140。操作槽140可以容纳手指，当用户将电子设备放置在槽体130内或是将电子设备从槽体130内取出时，用户可以通过操作槽140内的空间对电子设备进行握持、操作。在本申请的一些实施例中，无线充电模块20的厚度小于等于0.6㎜。
根据本申请的一些实施例，导引斜面131可以为间隔开的多个。例如，导引斜面131可以具有两个，两个导引斜面131位于槽体130所对应的两个相对的壁面上，两个导引斜面131对称排布。在底座组件10的厚度方向上且从无线充电模块20至槽体130的方向上，两个导引斜面131之间的距离逐渐增大，即两个导引斜面131可以构造成扩口状。由此，用户将电子设备放置在槽体130内或是将电子设备从槽体130内取出的过程中，导引斜面131可以为用户提供操作空间。
如图1及图5所示，根据本申请的一些实施例，导引斜面131可以呈环形，且沿槽体130开口的周缘方向延伸。可以理解的是，沿着底座组件10的厚度方向，可以将槽体130所对应的环形侧壁面1301分隔成多个环形面，多个环形面中的一个或多个可以构造成导引斜面131。导引斜面131可以构造成槽体130的至少部分侧壁面1301。例如，槽体130所对应的整个环形侧壁面1301均可以构造成导引斜面131。由此，环形的导引斜面131能够很好地导引电子设备的滑入与滑出。
如图2-图3及图5所示，根据本申请的一些实施例，底座组件10可以包括第一盖体110和第二盖体120。第二盖体120与第一盖体110连接。例如，第一盖体110与第二盖体120可以固定连接。第一盖体110与第二盖体120也可以可拆卸地连接。无线充电模块20可以位于第一盖体110和第二盖体120之间。例如，第一盖体110与第二盖体120可以扣合在一起，至少部分第一盖体110与第二盖体120间隔开以构造出安装空间100，无线充电模块20可以位于该安装空间100内。第二盖体120朝向第一盖体110凸出以构造出槽体130。由此，可以利用第一盖体110与第二盖体120构造出安装空间100以容纳无线充电模块20，直接在第二盖体120上构造槽体130，结构设置简单，可以减小设置成本。
在本申请的一些实施例中，第一盖体110可以与第二盖体120卡接。例如，第一盖 体110可以设有第一配合部，第二盖体120可以设有适于与第一配合部配合连接的第二配合部，第一配合部和第二配合部中的一个为凹槽，另一个为凸块，或者第一配合部和第二配合部中的一个为卡槽，另一个为卡勾。由此，可以实现第一盖体110与第二盖体120的连接，从而便于无线充电模块20的安装与拆卸。
在本申请的一些实施例中，第一盖体110可以与第二盖体120通过连接件连接。例如，第一盖体110可以具有第一螺纹孔，第二盖体120可以具有第二螺纹孔，螺纹紧固件可以依次穿过第一螺纹孔和第二螺纹孔，螺纹紧固件可以与第一螺纹孔螺纹连接，螺纹紧固件也可以与第二螺纹孔螺纹连接。由此，可以实现第一盖体110与第二盖体120的连接，从而便于无线充电模块20的安装与拆卸。
在本申请的一些实施例中，第二盖体120可以为非金属件。由此，可以避免第二盖体120对无线充电模块20充电性能的影响。例如，第二盖体120可以为橡胶件或塑料件。在本申请的一些实施例中，第一盖体110可以为金属件。由此，可以提高第一盖体110的散热速率，无线充电模块20在工作过程中产生的热量可以通过第一盖体110快速地散去。
如图2-图3及图5所示，根据本申请的一些实施例，无线充电器1还包括散热片40，散热片40位于底座组件10内。散热片40与无线充电模块20连接。由此，可以利用散热片40对无线充电模块20及底座组件10进行散热，从而可以提高无线充电器1的散热性能，进而可以提高无线充电器1的使用性能。
在本申请的一些实施例中，散热片40可以为多个。由此，可以利用多个散热片40对无线充电模块20及底座组件10进行散热，从而可以提高散热片40对无线充电器1的散热效率。在本申请的一些实施例中，散热片40可以为金属件。例如，在本申请的一些示例中，散热片40可以为铝合金片。由此，可以提高散热片40的散热效率。
如图4-图5所示，根据本申请的一些实施例，无线充电器1还可以包括胶垫30，胶垫30与底座组件10粘接，胶垫30位于底座组件10的远离槽体130的一侧。由此，胶垫30可以增加底座组件10的表面粘附性能，从而可以提高无线充电器1的放置稳定性。进一步地，如图4-图5所示，胶垫30可以形成为环形件，胶垫30可以沿着底座组件10的边缘延伸。由此，可以避免由于胶垫30的设置影响无线充电器1的散热性能。
根据本申请的一些实施例，无线充电模块20可以为多个。由此，可以提高无线充电器1的充电效率。
根据本申请的一些实施例，无线充电模块20可以包括主板210和无线充电线圈 200。无线充电线圈200与主板210通讯连接。例如，无线充电线圈200可以与主板210直接电连接。无线充电线圈200可以焊接在主板210上。无线充电线圈200也可以与主板210间接电连接。无线充电线圈200可以与主板210通过导线连接。无线充电线圈200与散热片40连接。由此，无线充电模块20可以通过无线充电线圈200发射电磁信号，主板210对无线充电线圈200具有控制作用。无线充电线圈200是热量产生的主要来源，散热片40可以对无线充电线圈200进行散热。
如图5所示，在本申请的一些实施例中，散热片40可以具有通孔400，无线充电线圈200可以位于通孔400内。由此，可以将无线充电线圈200设于散热片40，从而可以提高无线充电线圈200的安装稳定性，还可以提高散热片40与无线充电线圈200的结构整装性，可以减小散热片40与无线充电线圈200的整体厚度，从而可以减小无线充电器1的厚度，进而可以提高无线充电器1的美观性且方便用户携带。另外，还可以提高散热片40与无线充电线圈200的接触面积，从而可以使得无线充电线圈200的热量快速地传递给散热片40，散热片40可以将热量散发出去，从而可以提高无线充电器1的散热效率。
在本申请的一些实施例中，散热片40可以与无线充电线圈200通过胶粘层连接。由此，可以简化将散热片40与无线充电线圈200连接起来的操作。进一步地，胶粘层可以为导热胶粘层。由此，可以提高热量从无线充电线圈200传递到散热片40的效率。
下面参考图1-图5详细描述根据本申请实施例的无线充电器1。值得理解的是，下述描述仅是示例性说明，而不是对本申请的具体限制。
如图1-图5所示，根据本申请实施例的无线充电器1，包括底座组件10、无线充电模块20、胶垫30和散热片40。
具体而言，如图2-图3及图5所示，底座组件10可以包括第一盖体110和第二盖体120。第一盖体110与第二盖体120可以扣合在一起，第二盖体120的边缘与第一盖体110的边缘卡接。第一盖体110的中间区域与第二盖体120的中间区域间隔开以构造出安装空间100，无线充电模块20可以位于该安装空间100内。第二盖体120朝向第一盖体110凸出以构造出槽体130。槽体130的形状与电子设备的形状可以匹配，电子设备可以容纳在槽体130。
如图2-图3及图5所示，槽体130所对应的侧壁面1301可以朝向远离槽体130的方向倾斜以形成导引斜面131，导引斜面131与槽体130的底壁1302之间的夹角可以为钝角(即大于九十度且小于一百八十度的角)。导引斜面131可以形成为环形的圆滑曲面。导引斜面131可以与槽体130的底壁1302圆滑过渡。槽体130所对应的侧壁 面1301的一部分可以朝向远离槽体130的方向凹陷形成操作槽140。操作槽140可以容纳手指，当用户将电子设备放置在槽体130内或是将电子设备从槽体130内取出时，用户可以通过操作槽140内的空间对电子设备进行握持、操作。槽体130的底壁1302可以设有容纳槽150，容纳槽150可以用于容纳电子设备的摄像头组件，以使得电子设备的表面与底壁1302更贴合。
如图2-图3及图5所示，无线充电模块20包括无线充电线圈200和主板210，无线充电线圈200和主板210电连接。无线充电线圈200靠近主板210的中间区域。无线充电线圈200可以与主板210电连接。散热片40位于底座组件10内。散热片40可以形成为薄壁件。散热片40为金属件，例如，散热片40可以为铝合金。散热片40具有通孔400。散热片40可以与主板210连接(如粘接、卡接或螺纹连接)。无线充电线圈200可以位于通孔400内。无线充电线圈200与通孔400的壁面连接(如粘接、卡接或螺纹连接)。散热片40可以提高无线充电器1的散热性能，从而可以提高无线充电器1的使用性能。如图4-图5所示，胶垫30可以形成为环形件。胶垫30与底座组件10粘接，胶垫30位于底座组件10的远离槽体130的一侧。
本申请实施例的无线充电器1，通过仿照电子设备的外形设计无线充电器1的槽体130，槽体130的形状仿照电子设备的外形进行设计，既可保证电子设备内的无线充电线圈接收端与无线充电器1内的无线充电线圈200的位置对准度，以确保无线充电器1的充电效率无损失，不会因为电子设备内的无线充电线圈接收端与无线充电器1内的无线充电线圈200之间的位置错位而损失，也可方便用户拿取电子设备。用户只需将电子设备放进槽体130内，无需再次进行对准等其他动作，便可确保了无线充电的效率。
另外，通过在无线充电器1内增加金属的散热片40，当无线充电线圈200工作时会产生一定的热量，可以利用散热片40来将热量均匀散开，解决了无线充电器1的发热问题。而且在体130内设置的导引斜面131有利于电子设备滑动出来，这样便可方便用户取出手机。胶垫30还可以提高无线充电器1的防滑性能。
