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、完整地描述。显然，所描述的实施例仅仅是本申请的一部分实施例，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在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在本申请的描述中，需要理解的是，术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“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。
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，可以根据具体情况理解上述术语在本申请中的具体含义。
参照图1和图2，本申请实施例提供了一种无线充电设备，包括便携容器1，便携容器1上设置有感应线圈2和用于安装移动设备3的安装座4。当移动设备3安装在所述安装座4内时，感应线圈2与安装座4内的移动设备3形成闭合回路。无线充电设备还包括无线充电端，所述无线充电端包括通电线圈5，通电线圈5可通入交流电以产生磁场。当感应线圈2位于磁场内时，感应线圈2中产生感应电流，并能够为移动设备3充电。
本申请实施例提供的无线充电设备包括便携容器1，这里的便携容 器1可以为包具或服饰配件等。人们习惯将移动设备3放置于便携容器1中，以随身携带。便携容器1上设置有感应线圈2和用于安装移动设备3的安装座4，感应线圈2与安装座4内的移动设备3可形成闭合回路。这里的移动设备3可以是手机等移动电子设备，也可以是为移动电子设备进行充电的移动电源。移动设备3可沿图2中箭头所示方向安装到安装座4内。当移动设备3为移动电源时，移动电源从安装座4内取出即可为移动电子设备充电。该无线充电设备还包括无线充电端，所述无线充电端包括通电线圈5，通电线圈5可通入交流电以产生磁场。图1中的交流电源6用于为通电线圈5提供交流电。当感应线圈2位于磁场内时，感应线圈2中可产生感应电流，以便为移动设备3充电。因此可将通电线圈5设置于便携容器1经常放置的位置，通过使用者的习惯性动作即可使便携容器1上的感应线圈2位于通电线圈5产生的磁场内，利用便携容器1的闲置时间达到为移动设备3充电的目的，从而无需使用者特意将移动设备3与插座进行连接，进而方便了使用。另外，本申请实施例提供的无线充电设备无需与插座连接，因此不会受到空余插座数目的限制，同样方便了使用。
为了提高连接的稳定性，参照图2，在一个实施例中，安装座4上设置有多个接触端41，所述多个接触端41中的至少两个分别与感应线圈2的两端通过导线9连接。举例来说，如果感应线圈2的数量为一个，则接触端41的数量为两个；如果感应线圈2的数量为两个，则接触端41的数量为四个。接触端41可以包括弹簧(图中未示出)。当移动设备3安装于安装座4内时，每个接触端41均与移动设备3上的弹性触片31弹性接触，以使每个感应线圈2均与安装座4内的移动设备3形成闭合回路。由于非弹性接触随着使用次数的增加会存在接触不良的情况，因此相比非弹性接触，本实施例通过接触端41的弹性来避免接触不良的问题，从而提高了连接的稳定性。
为了提高充电效率，在一些实施例中，无线充电端还包括铁芯7，这里的铁芯7由导磁能力很强的磁性物质制成。通电线圈5缠绕于铁芯7上，这样可显著增强磁场，从而增大感应线圈2中产生的电流，进而提高充电效率。
本申请的无线充电设备是利用电磁感应原理来为移动设备3进行充电的：在通电线圈5上施加一定频率的交流电，即可产生磁场，位 于磁场内的感应线圈2中会因电磁感应产生一定的电流。
电磁感应基本公式：
Figure PCTCN2018075554-appb-000001
对于正弦交流电，磁通量φ＝B m sin ωtS，其中，ω＝2πf，代入电磁感应基本公式，得：u＝2πfNB mS cosωt
其中，f为电源频率，N为线圈匝数，B m为磁通密度，S为磁通截面积。
根据公式u＝2πfNB mS cosωt得知，增大磁通截面积S可使感应电动势u增大，充电效率则会相应增大，因此在一些实施例中，无线充电端还可以包括固定座8。该固定座8可固定于墙体或其他物体上，铁芯7的一端固定于固定座8上，另一端高于或平齐于铁芯7与固定座8的连接处。通电线圈5缠绕于铁芯7上靠近固定座8的位置，这样使得铁芯7可以作为悬挂便携容器1的结构，保证便携容器1挂在铁芯7上不会掉。可以理解的是，铁芯7也可以呈弯钩状，只要能够保证便携容器1挂在铁芯7上不会滑落即可。当便携容器1挂于铁芯7上时，铁芯7穿过感应线圈2，此时的磁通截面积S最大，相应地感应电动势u最大，从而最大程度地提高了充电效率。
便携容器1可以为包具，相比衣物，包具不需要经常洗，可减少对感应线圈2和安装座4的损坏。另外，包具的容量相对较大，便于设置安装座4。包具包括包体11和包带12，感应线圈2设置于包带12上。具体地，感应线圈2可设置于包带12内，也可缠绕于包带12外。安装座4设置于包体11内，感应线圈2的两端与安装座4均通过导线9连接，导线9置于包体11内。当包具通过包带12挂于铁芯7上时，铁芯7穿过感应线圈2，此时的磁通截面积S最大，相应地感应电动势u最大，从而最大程度地提高了充电效率。
在一些实施例中，无线充电端不包括铁芯，只要将便携容器1放置于无线充电端附近，使便携容器1上的感应线圈2位于通电线圈5产生的磁场内，就可以利用便携容器1的闲置时间达到为移动设备3充电的目的。
当感应线圈2中产生电流时，感应线圈2会发热，这会造成包带12的温度过高。为了避免上述问题，参照图1，固定座8上设置有散热件10。散热件10用于对挂在铁芯7上的包带12进行散热，由此可避免包带12的温度过高。
散热件10可以为风扇，以利用空气的对流来实现散热降温。风扇的数量会影响对包带12的散热效果，数量越多，对包带12的散热效果越好，但数量过多会导致无线充电设备的成本过高。因此在一个实施例中，风扇的数量为两个，两个风扇分别设置于铁芯7的上下两侧。由此一方面可对铁芯7上下两侧的包带12进行散热，从而提高散热效果，另一方面可避免因风扇的数量过多而导致的成本过高的问题。
散热件10可以为吸热或导热材料，如石墨烯片等，其可以贴设于固定座8上。
感应线圈2的数量会影响充电效率，数量越多，则充电效率越高，但数量过多会导致无线充电设备的成本过高。因此，在一个实施例中，感应线圈2的数量为两个，一方面可提高充电效率，另一方面可避免成本过高。
为了方便使用，参照图1，便携容器1的外侧设置有显示器A。显示器A与安装座4内的移动设备3连接，用于显示移动设备3的电量，由此在查看移动设备3的剩余电量时或查看移动设备3已经充了多少电时，直接通过显示器A查看即可，无需将移动设备3从便携容器1内拿出，从而方便了使用。
参照图1，显示器A包括多个LED指示灯a，显示器A可以挂设于便携容器1的外侧，显示器A挂设的这种设置方式使得制作工艺更加简单。
感应线圈2可以设置于包带12内，以防止与人体接触，从而避免了因感应线圈2漏电对人体造成的伤害，同时避免了因感应线圈2发热带来的不良体验。包带12可以由隔热材料制作，可进一步避免因感应线圈2发热带来的不良体验。包体11内还可以设置有散热结构(图中未示出)，以方便散热。这里的散热结构可以是散热能力强的材料，例如石墨、金属，也可以是比热容低的材料，以避免热量积累过多，还可以是散热孔等等。具体地，可在包体11的两个侧面B内设置散热能力强的材料，在包体11的两个正面C内设置热容低的材料。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所附权利要求的保护范围为准。
