Description

一种自动定位无线感应接收贴及充电装置 技术领域
本实用新型涉及充电设备，尤其涉及一种自动定位无线感应接收贴及充电装置。
背景技术
随着人们拥有越来越多的智能设备，譬如手机、平板电脑等等，所需要的充电设备也越来越多。充电设备通常是由外部电能输入(譬如市电)然后转换成适合智能设备的电压电流并向智能设备输出。为了提高使用方便性，市面上也出现了许多无线充电设备。无线充电的基本原理是在无线发射线圈形成电磁波，用无线接收线圈接收电磁波并且转化成电能输入到被充电设备中。对于一些不带有无线充电功能的设备，可以固定一个无线感应接收贴来实现无线充电。无线充电一般要求无线接收线圈与无线发射线圈对齐，避免效能损失，因此带有无线感应接收贴的设备需要手动对准位置进行无线充电，使用的方便性有待提高。
实用新型内容
本实用新型的目的在于为克服现有技术的缺陷，而提供一种自动定位无线感应接收贴及充电装置，以提高使用方便性。
为实现上述目的，本实用新型采用以下技术方案：一种自动定位无线感应接收贴，无线感应接收贴用于紧贴固定在被充电设备的背面，无线感应接收贴包括有无线接收线圈，无线接收线圈的周围间隔设有至少两个的磁铁片或铁磁性片，磁铁片或铁磁性片用于与外部充电模块上无线发射线圈周围的磁铁块产生磁吸力以将无线接收线圈定位对准无线发射线圈。磁铁片或铁磁性片有四个。磁铁片或铁磁性片的厚度不大于2mm。
无线感应接收贴还包括有插头和电路板，插头与电路板电连接，电 路板与无线接收线圈电连接，插头用于插接被充电设备并将无线接收线圈形成的电能传输至被充电设备。插头是Type-C插头、Micro-USB插头、Lightning插头其中一种。插头与电路板通过柔性电路板实现电连接。
本实用新型还公开了一种充电装置，其包括无线感应接收贴以及充电模块，充电模块上设有无线发射线圈，无线发射线圈周围设有磁铁块，磁铁块排布与无线感应接收贴内的磁铁片或铁磁性片的排布相对应。
本实用新型与现有技术相比的有益效果是：通过在无线接收线圈设置间隔的磁铁片或铁磁性片，只需要将被充电设备靠近充电模块，就可以通过磁吸力实现自动定位对准，无需手工进行定位对准，并吸住了被充电设备避免滑动或掉落，提高了使用方便性及安全性，同时也保证了准确定位，减少电能损失，提高了充电效率。
附图说明
图1为本实用新型无线感应接收贴分解图。
图2为本实用新型充电装置立体图。
需要说明的是，以上视图所示产品均为适应图纸大小及视图清楚而进行了适当的缩小/放大，并不对视图所示产品大小加以限制。
具体实施方式
为了更充分理解本实用新型的技术内容，下面结合具体实施例对本实用新型的技术方案作进一步介绍和说明。
第一实施例
第一实施例是一种无线感应接收贴，具体如图1所示。无线感应接收贴包括有插头15、电路板13和用于接收电磁波的无线接收线圈11。插头15与电路板13通过柔性电路板14实现电连接，电路板13与无线接收线圈11电连接。插头15用于插接在被充电设备并将无线接收线圈11形成的电能传输至被充电设备中。在具体实施时，插头15可以是Type-C插头、Micro-USB插头、Lightning插头其中一种，以满足持有不同设备的各类 用户的需求。
如图1所示，无线接收线圈11的周围间隔设有4个的磁铁片12。磁铁片12厚度应不大于2mm，譬如1mm，避免无线感应接收贴整体厚度过大。磁铁片12用于与外部充电模块上无线发射线圈周围的磁铁块产生磁吸力以将无线接收线圈11定位对准无线发射线圈，也即是通过磁吸力将无线感应接收贴及被充电设备自动定位至最佳的充电位置，避免使用者手动调整被充电设备位置。在本实施例中，磁铁片12有四个，均匀分布在无线接收线圈11的周围。而在其他实施例中，磁铁片可以只设置2个或者3个，但磁吸力会相对减弱，自动定位效果有削减。在其他实施例中，磁铁片也可以设置多于4个，以增强磁吸力，但整体成本会升高。在其他实施例中，磁铁片也可以换成铁磁性片，譬如铁片。
如图1所示，无线感应接收贴通过前后两片薄膜片16将无线接收线圈11、电路板13、磁铁片12以及部分的柔性电路板14夹紧，避免零部件散乱。薄膜片16可以选用薄的材质制成，譬如合成纸材料。其中一片薄膜片16的外侧面可以涂布粘胶或贴上双面胶，以便于无线感应接收贴固定在被充电设备的背面上。
第二实施例
第二实施例是一种充电装置。如图2所示，充电装置包括第一实施例的无线感应接收贴10以及一个充电模块20。充电模块20内设有无线发射线圈21，而无线发射线圈21周围设有4个磁铁块22，磁铁块22排布与无线感应接收贴10内的磁铁片的排布相对应。在使用时，将无线感应接收贴10紧贴固定在被充电设备的背面，将插头15插入于被充电设备中，随后将被充电设备放置在充电模块20上，然后磁铁块22与磁铁片的磁吸力将无线感应接收贴10及被充电设备定位至无线发射线圈21对准无线接收线圈，充电模块20接上电源后便可以对被充电设备进行无线充电。
以上陈述仅以实施例来进一步说明本实用新型的技术内容，以便于读者更容易理解，但不代表本实用新型的实施方式仅限于此，任何依本实用新型所做的技术延伸或再创造，均受本实用新型的保护。
工业实用性
本实用新型与现有技术相比的有益效果是：通过在无线接收线圈设置间隔的磁铁片或铁磁性片，只需要将被充电设备靠近充电模块，就可以通过磁吸力实现自动定位对准，无需手工进行定位对准，并吸住了被充电设备避免滑动或掉落，提高了使用方便性及安全性，同时也保证了准确定位，减少电能损失，提高了充电效率。
