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充电装置进行详细地说明。
请参见图1、图2和图3，图1为本申请实施例提供的充电装置的结构示意图，图2为本申请实施例提供的充电装置的截面的结构示意图，图3为本申请实施例提供的充电装置的局部结构示意图，如图1、图2和图3所示，该充电装置包括：
底座10，底座10设置有第一感应器件11和电磁机构12；
上盖20，上盖20与底座10转动连接，上盖20设置有第二感应器件21，上盖20用于放置待充电的电子设备；
充电线圈13，设置于所述底座10；
所述充电装置通过所述电磁机构12对放置于所述上盖20上的电子设备进行吸附，并通过所述充电线圈13对放置于所述上盖20上的电子设备无线充电；
其中，上盖20与底座10处于第一相对位置时，第一感应器件11与第二感应器件21处于第一状态，上盖20与底座10处于第二相对位置时，第一感应器件11与第二感应器件21处于第二状态，第一感应器件11与第二感应器件21在所述第一状态和所述第二状态下产生的电信号不同，以使电磁机构12产生不同大小的磁力。
本申请实施例中的充电装置可用作设备支架，用于放置或支撑电子设备，也可用作无线充电设备，如通过无线充电线圈对放置在其上的电子设备进行无线充电。
如图1所示，所述充电装置包括底座10和上盖20，且上盖20与底座10转动连接，使得上盖20可相对底座10转动，具体地，底座10和上盖20可以是上下转动连接结构，也可以是内外套设转动连接结构，如底座10套设在上盖20外，上盖20可以轻易相对于底座10顺时针或逆时针旋转。其中，上盖20可作为放置待充电的电子设备的台面，底座10则用于支撑上盖20，并提供磁吸作用，以吸住放置在上盖20上的电子设备，实现电子设备的稳定放置。具体地，如图2所示，底座10上可设置有电磁机构12，可与电子设备上的磁力机构配合，产生磁吸力。
特别地，本申请实施例中，为实现稳定放置电子设备的同时，方便用户从所述充电装置上取下电子设备，可在所述充电装置上设置感应器件来检测用户拿取电子设备的动作，并通过改变电磁机构12的磁力大小，来减少此时所述充电装置对所述电子设备的磁吸力，使得用户能够轻松地取下所述电子设备，而无需使用较大力气或使用双手操作来分离所述充电装置与所述电子设备。
具体地，如图2和图3所示，可在底座10设置第一感应器件11和电磁机构12，在上盖20设置第二感应器件21，第一感应器件11与第二感应器件21可感应上盖20与底座10的相对位置变化，随上盖20与底座10的相对位置的不同，而处于不同状态，并产生不同的电信号，所述充电装置可根据电信号的变化，控制电磁机构12产生不同大小的磁力，以在上盖20上放置有电子设备的状态下，通过电磁机构12产生较强的磁力来吸住电子设备，使所述电子设备保持稳定放置和精准对齐，在用户转动上盖20以将电子设备取下的状态下，通过电磁机构12产生较小的磁力，以方便用户轻松分离所述电子设备与所述充电装置，而不会因磁吸力过大而难以分离。
其中，所述第一相对位置和所述第二相对位置可以分别为上盖20未相对底座10转动时的初始位置状态和上盖20相对底座10转动时的位置状态，例如，上盖20在未受外力作用下而与底座10保持自然状态时，上盖20与底座10可处于第一相对位置，上盖20在受外力作用下相对底座10转动时，上盖20与底座10可处于第二相对位置。
又例如，在使用中，用户将电子设备放置在上盖20上后，上盖20与底座10处于第一相对位置，如图4所示，当用户握住放置在上盖20上的电子设备400并向一定方向转
动时，上盖20也相对底座10转动，从而上盖20与底座10由第一相对位置变化为第二相对位置。
在上盖20与底座10的相对位置发生变化时，相应地，第一感应器件11与所述第二感应器件21的状态也发生变化，例如，第一感应器件11与所述第二感应器件21可由接触状态变化为非接触状态，或者相对位置状态发生变化，如由位置上下对齐状态变化为不对齐状态等。而第一感应器件11与第二感应器件21随着状态的变化，可产生电信号的变化，例如，可在不同状态下产生不同大小的电流，或者在第一状态下产生电信号，而在第二状态下电信号为零。
这样，所述充电装置可依据第一感应器件11与第二感应器件21产生的不同电信号，来判断上盖20与底座10的相对位置变化，进而控制电磁机构12改变磁力大小，使得用户在拿取电子设备而转动上盖20时，所述充电装置对所述电子设备的磁吸力变小或消失，从而方便用户轻松取下电子设备。
例如，当用户握住放置在上盖20上的电子设备并向一定方向转动时，上盖20也相对底座10转动，从而上盖20与底座10的相对位置变化，第一感应器件11与第二感应器件21的状态也随之变化，所述充电装置检测到第一感应器件11与第二感应器件21产生的电信号变化，从而控制电磁机构12的磁力变小或消失，这样，用户能够轻松地从上盖20上取下电子设备。
所述充电装置可为无线充电设备，具体地，如图2所示，底座10上还设置有充电线圈13，用于对放置在上盖20上的电子设备无线充电。具体地，可在底座10的中部设置环绕的充电线圈13，使底座10结构保持美观，也有利于铺设一定面积的充电线圈，来保证充电性能。
这样，不仅能够通过电磁机构12产生磁吸力来吸附放置在上盖20上的电子设备，使其保持稳定并对使二者线圈对准，还能够通过充电线圈13对电子设备进行无线充电，改善现有无线充电设备在对电子设备进行充电时不便取下电子设备的问题。
可选地，电磁机构12包括多个在底座10上分散布置的电磁体。
一种实施方式中，电磁机构12可以为电磁体，且如图2所示，可以在底座10上分散布置多个电磁体，以保证其产生的磁力在多个位置分布，进而保证较好的磁吸效果。具体地，所述多个电磁体可以在底座10上呈圆圈状均匀分布，在底座10上设有充电线圈13时，所述多个电磁体可绕充电线圈13均匀分布，以保证其产生的磁力的均匀分布，确保对放置在其上的电子设备的良好吸附效果。
且该实施方式中，由于电磁机构12为电磁体，从而可通过电信号来控制电磁机构12产生的磁力大小，如通过改变电磁机构12的通电电流，来改变电磁机构12产生的磁力大小，或者，通过对电磁机构12通电或不通电来控制电磁机构12产生磁力或磁力消失。
可选地，如图2所示，所述充电装置还包括复位件30，复位件30的一端与底座10连接，另一端与上盖20连接；
在所述上盖20与所述底座10在外力作用下由所述第一相对位置转动至所述第二相对位置的过程中，所述复位件30发生形变；在失去所述外力作用下，所述复位件30恢复形变，使上盖20与底座10由所述第二相对位置复位至所述第一相对位置。
一种实施方式中，所述充电装置还包括复位件30，用于对上盖20与底座10的相对位置状态进行复位，其中，复位件30的两端分别连接底座10与上盖20。
具体地，复位件30分别具有初始状态(即非形变状态)和形变状态，在上盖20与底座10处于所述第一相对位置时，复位件30处于初始状态，其中，所述第一相对位置可以是上盖20在未受外力作用下与底座10的自然状态；而在上盖20与底座10处于所述第二相对位置，如上盖20在外力作用下相对底座10转动，使得上盖20与底座10由所述第一相对位置转动至所述第二相对位置时，复位件30处于形变状态，即复位件30发生形变，其中，所述第二相对位置可以是上盖20在受外力作用下相对底座10转动后的位置状态。当外力作用消失后，复位件30可通过形变作用推动上盖20相对底座10反向转动，使上盖20回到原来的相对位置，即使上盖20与底座10由所述第二相对位置复位至所述第一相对位置。
这样，通过该实施方式，能够实现上盖20与底座10的相对位置的自动复位，而无需用户手动复位。
可选地，如图6所示，复位件30包括第一弹片32；
底座10开设有第一开孔，第一弹片32位于所述第一开孔内；
上盖20相对底座10转动时，第一弹片32与所述第一开孔内壁相互作用，使得第一弹片32发生形变。
一种具体的实施方式中，复位件30可包括第一弹片32，这样，当上盖20相对底座10转动时，第一弹片32可在外力作用下与所述第一开孔内壁相互作用从而发生形变，当外力消失时，第一弹片32可在形变的弹力作用下推动上盖20反向转动，回到原来的位置，实现复位。这样，通过采用弹片作为复位件，不仅结构简单，易于实现，且成本低廉。
需说明的是，如图2所示，底座10与上盖20为上下转动连接结构时，所述第一开孔位于底座10朝向上盖20的一面，且可位于底座10的中央，充电线圈13则环绕该第一开孔布设，电磁机构12则环绕充电线圈13均匀布置，这样，能够保证底座10结构对称和紧凑，各器件布置不会占用过多空间。
可选地，如图6所示，复位件30还包括定位柱31；
定位柱31的一端与上盖20连接，另一端插入所述第一开孔内，并与第一弹片32相抵触；
上盖20相对底座10转动时，带动定位柱31转动，第一弹片32在定位柱31的转动作用下发生形变。
一种更具体的实施方式中，复位件30还可包括定位柱31，其中，定位柱31的一端连接上盖20朝向底座10的下侧面，定位柱31的另一端则插入底座10朝向上盖20的一
面的第一开孔内，并与所述第一开孔内的第一弹片32相抵触。这样，当上盖20在外力作用下相对底座10转动时，将带动定位柱31转动，此时定位柱31将对第一弹片32施加压力作用，使得第一弹片32发生形变，当外力消失时，第一弹片32可在形变的弹力作用下推动定位柱31反向转动，定位柱31则带动上盖20反向转动，回到原来的位置，实现复位。
这样，通过采用弹片和定位柱作为复位件，能进一步提高所述充电装置的复位功能的可靠性。
可选地，如图5所示，底座10通过轴承40与上盖20连接；
轴承40的一面与底座10卡合，轴承40的另一面与上盖20卡合，轴承40可随上盖20相对底座10转动。
一种实施方式中，底座10可通过轴承40与上盖20连接，其中，轴承40可分别与底座10和上盖20卡合连接，具体地，底座10上可设置有与轴承40卡合的凹槽，使得轴承40可卡合在底座10的该凹槽中。当转动上盖20时，上盖20和轴承40可一起相对底座10转动，从而实现底座与上盖20的转动连接。
可选地，第一感应器件11为霍尔器件，第二感应器件21复用电磁机构12。
一种实施方式中，可以采用霍尔器件和磁性机构来作为所述充电装置的感应器件，来感应上盖20与底座10的相对位置变化。具体地，底座10上的第一感应器件11可以为霍尔器件，上盖20上的第二感应器件21为磁铁，一种实施方式中，可以复用电磁机构12作为第二感应器件21，即无需在底座10上再额外设置磁性机构，例如，可以复用电磁机构12中的一块电磁体作为第二感应器件21，其中，霍尔器件可以感应磁性机构的磁力线，从而产生电信号，当霍尔器件与磁性机构靠近时，霍尔器件可以产生较强的电信号如电流，当霍尔器件与磁性机构分离时，霍尔器件可以产生电信号变弱或消失。
基于此原理，在上盖20与底座10的相对位置发生变化时，所述霍尔器件与所述磁性机构的相对位置状态也随之变化，从而所述霍尔器件产生的电信号发生变化，由此检测到上盖20与底座10的相对位置变化情况，进而能够判断出用户转动上盖20以拿取电子设备的情况。
下面以所述充电装置作为无线充电设备对电子设备无线充电的场景为例，来说明所述充电装置的工作原理：
当用户将电子设备放到无线充电设备上时，该无线充电设备可通过近场通信(Near Field Communication，NFC)等判定电子设备存在，从而给电磁机构12通电，同时充电线圈13开始工作，电磁机构12的吸力可助于更好对位电子设备，提高充电效率。当电子设备充好电后，用户可单手将电子设备做小幅度旋转，因磁力以及摩擦力上盖20将同电子设备一起旋转，从而上盖20上的磁铁相对底座10上的霍尔器件位置发生变化，霍尔器件信号随之变化，无线充电设备根据霍尔器件信号变化，切断电磁机构12的电流，无线充电设备与电子设备间的吸力消失，使得用户能够轻松取走电子设备，上盖20在第一弹片
32的作用下也旋转回到原来的位置。
可选地，第一感应器件11为第二弹片，第二感应器件21为第三弹片；
其中，所述第一状态为接触状态，所述第二状态为非接触状态，或者，所述第一状态为非接触状态，所述第二状态为接触状态；
所述第二弹片与所述第三弹片接触时形成回路，产生电信号。
另一种实施方式中，可以采用金属弹片作为所述充电装置的感应器件，来感应上盖20与底座10的相对位置变化。具体地，底座10上的第一感应器件11可以为第二弹片，上盖20上的第二感应器件21为第三弹片，其中，所述第二弹片和第三弹片可以接入电路中，用作电路开关，当所述第二弹片和第三弹片接触时，该电路导通，从而产生电信号，当所述第二弹片和第三弹片分离未接触时，该电路断开，从而电信号消失。
基于此原理，在上盖20与底座10的相对位置发生变化时，所述第二弹片与所述第三弹片的相对位置状态也随之变化，具体为在接触状态与非接触状态之间变化，从而使得所在电路产生的电信号发生变化，由此检测到上盖20与底座10的相对位置变化情况，进而能够判断出用户转动上盖20以拿取电子设备的情况。
且一种实施方式中，可以是在上盖20与底座10处于第一相对位置时，所述第二弹片与所述第三弹片处于接触状态，从而产生电信号，在上盖20与底座10处于第二相对位置时，所述第二弹片与所述第三弹片处于非接触状态；另一种实施方式中，则是在上盖20与底座10处于第一相对位置时，所述第二弹片与所述第三弹片处于非接触状态，在上盖20与底座10处于第二相对位置时，所述第二弹片与所述第三弹片处于接触状态，从而产生电信号。
可选地，所述第二弹片设置在底座10的侧边的第一位置，所述第三弹片设置在上盖20的侧边的第二位置；
在上盖20与底座10处于所述第一相对位置时，所述第二位置与所述第一位置正相对，所述第二弹片与所述第三弹片接触；在上盖20与底座10处于所述第二相对位置时，所述第二位置与所述第一位置不相对，所述第二弹片与所述第三弹片不接触；
或者，在上盖20与底座10处于所述第一相对位置时，所述第二位置与所述第一位置的中点对齐，所述第二弹片与所述第三弹片不接触；在上盖20与底座10处于所述第二相对位置时，所述第二位置与所述第一位置的端点对齐，所述第二弹片与所述第三弹片接触。
一种实施方式中，如图7或图8所示，第二弹片110设置在底座10的侧边的第一位置，第三弹片210设置在上盖20的侧边的第二位置，其中，所述第一位置与所述第二位置可以是上下对应的位置。具体地，第二弹片110与第三弹片210的设置可以有两种不同方式。
如图7所示，一种方式中，第二弹片110设置在底座10的侧边的第一位置，第三弹片210设置在上盖20的侧边正对所述第一位置的第二位置。这样，在所述充电装置处于正常工作状态时，上盖20与底座10处于所述第一相对位置，所述第二位置与所述第一位
置正相对，此时第二弹片110与第三弹片210接触；在所述充电装置处于上盖20相对底座10旋转状态时，上盖20与底座10处于所述第二相对位置时，所述第二位置与所述第一位置不相对，此时第二弹片110与第三弹片210不接触。
如图8所示，另一种方式中，第二弹片110设置在底座10的侧边的第一位置，第三弹片210设置在上盖20的侧边正对所述第一位置的中部的第二位置，即所述第一位置所在区域大于所述第二位置所在区域。这样，在所述充电装置处于正常工作状态时，上盖20与底座10处于所述第一相对位置，所述第二位置与所述第一位置的中点对齐，此时第二弹片110与第三弹片210不接触；在所述充电装置处于上盖20相对底座10旋转状态时，上盖20与底座10处于所述第二相对位置，所述第二位置与所述第一位置的其中一端点对齐，此时第二弹片110与第三弹片210接触。
下面以所述充电装置作为无线充电设备对电子设备无线充电的场景为例，来说明所述充电装置的工作原理：
如图7所示，无线充电设备在工作状态下，上盖20上的第三弹片210和底座10上的第二弹片110接触在一起，使得接入电路处于导通状态，产生电信号。电子设备充电完成后，用户可单手将电子设备做小幅度旋转，因磁力以及摩擦力上盖20同电子设备一起旋转，上盖20上第三弹片210和底座10上第二弹片110分开，接入电路处于断开状态，电信号消失，无线充电设备根据该电信号变化切断电磁机构12的电流，无线充电设备与电子设备间的吸力消失，使得用户能够轻松取走电子设备，上盖20在第一弹片32的作用下也旋转回到原来的位置。
如图8所示，无线充电设备在工作状态下，上盖20上的第三弹片210和底座10上的第二弹片110为不接触状态，接入电路处于断开状态，不产生电信号。电子设备充电完成后，用户可单手将电子设备做小幅度旋转，因磁力以及摩擦力上盖20同电子设备一起旋转，旋转一定角度后，上盖20上第三弹片210和底座10上第二弹片110接触，使得接入电路处于导通状态，产生电信号，无线充电设备根据该电信号变化切断电磁机构12的电流，无线充电设备与电子设备间的吸力消失，使得用户能够轻松取走电子设备，上盖20在第一弹片32的作用下也旋转回到原来的位置。
这样，通过弹片接触或非接触来作为电路通断开关以产生电信号，进而能够通过检测该电信号变化来判断上盖20与底座10的相对位置状态，进而通过控制电磁机构12的磁力，来使用户方便取下电子设备。
可选地，底座10与上盖20之间还设置有锁定机构，用于锁定底座10与上盖20。
一种实施方式中，为了满足特定场景下使电子设备牢固吸附在所述充电装置上，如为满足用户在利用电子设备玩游戏场景下也能够持续给电子设备充电，可在所述充电装置上增加锁定机构，用于锁定底座10与上盖20，使二者处于固定的相对位置，从而使所述电磁机构12产生的磁力始终存在或保持不变，避免用户玩游戏时将电子设备和所述充电装置一起拿起，发生磁力消失或变小而导致电子设备从所述充电装置脱落的情况。
其中，所述锁定机构可以是插销，用户可以在特定场景下按下该插销来锁定底座10与上盖20。
可选地，上盖20用于放置电子设备的一侧设置有摩擦垫圈，用于在转动所述上盖20上放置的电子设备时，带动所述上盖20转动。
一种实施方式中，还可以在上盖20的外侧，即用于放置电子设备的一侧设置摩擦垫圈，这样，当用户想要拿取放置在上盖20的电子设备时而转动所述电子设备时，可以通过所述摩擦垫圈的摩擦力作用来更好地带动上盖20转动，进而使所述充电装置与所述电子设备间的磁吸力变小，方便用户更轻松地拿取电子设备。
可选地，所述充电装置中还设置有延时电路，用于在取走上盖20上的电子设备时，控制电磁机构12延迟恢复磁力。
一种实施方式中，还可在所述充电装置中还设置延时电路，例如，可在底座10上设置延时电路，这样，当用户转动上盖20以拿取放置在上盖20的电子设备时，电磁机构12的磁力变小或消失，而在上盖20失去外力作用后恢复至原位置时，可以通过所述延时电路来设置延迟时间，控制电磁机构12延迟上电或延迟恢复原来的通电电流，使电磁机构12的磁力延迟恢复至原来的大小，避免所述电子设备在用户拿走不远后再次被恢复的磁吸力吸住。
需说明的是，上盖20的材质可以是非金属，如玻璃、陶瓷、塑料等，以保证所述充电装置在作为无线充电设备使用时，具备较好的充电性能。
本申请实施例主要是通过增加旋转上盖、弹片和电磁机构来控制磁力大小，让用户通过小幅度的简单旋转，即可实现单手拿起电子设备而不将充电装置带起，提升用户体验。本申请实施例中的充电装置可应用但不限于对手机、平板、电子书阅读器等电子设备进行无线充电的无线充电设备。
本申请实施例中的充电装置，包括：底座，所述底座设置有第一感应器件和电磁机构；上盖，所述上盖与所述底座转动连接，所述上盖设置有第二感应器件，所述上盖用于放置待充电的电子设备；充电线圈，设置于所述底座；所述充电装置通过所述电磁机构对放置于所述上盖上的电子设备进行吸附，并通过所述充电线圈对放置于所述上盖上的电子设备无线充电；其中，所述上盖与所述底座处于第一相对位置时，所述第一感应器件与所述第二感应器件处于第一状态，所述上盖与所述底座处于第二相对位置时，所述第一感应器件与所述第二感应器件处于第二状态，所述第一感应器件与所述第二感应器件在所述第一状态和所述第二状态下产生的电信号不同，以使所述电磁机构产生不同大小的磁力。当需要将电子设备从上盖上取下时，用户可通过旋转上盖，使上盖与底座的相对位置发生变化，进而使电磁机构的磁力变小，这样，用户能够轻松地将电子设备与所述充电装置分离。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所
固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
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。
