Description
本发明涉及无线充电技术领域，特别是涉及一种无线充电收纳盒及无线充电耳机装置。
无线充电的充电器与用电装置之间以磁场传送能量，两者之间不用电线连接，日常可用于手机、耳机等电子产品的电池充电中。无线耳机不仅具有良好的声场和舒适度,而且便于携带,深受年轻人的喜爱。
目前，市面上常见的真无线耳机都需要适配专用的充电仓进行充电，一旦充电仓遗失,耳机将无法进行充电。而且金属触点错位或者氧化脏污后会导致断充,且弹针使用久后也会有无法回弹接触耳机的情况。此外，耳机需要固定在设定好的卡槽内才能完成充电,一旦耳机没有放好就有断充风险.而在同时拥有多 款耳机的情况下需要携带同样数量的充电器,使出行非常不方便。
基于此，有必要针对现有的耳机充电仓充电不便、耳机需要固定于预定的位置的问题，提供一种无线充电收纳盒及无线充电耳机装置。
一种无线充电收纳盒，包括收纳盒外壳、电源电路、无线充电发射模组；所述电源电路的输入端与电源接口连接，所述电源电路的输出端与所述无线充电发射模组的输入端连接；所述无线充电发射模组的发射线圈设于所述收纳盒内壁上，所述无线充电发射模组通过所述发射线圈发射电磁波。
优选地，该无线充电收纳盒还包括电池及逆变电路，所述电池的输出端与所述逆变电路的输入端连接，所述逆变电路的输出端与所述电源电路的输入端连接；所述逆变电路将所述电池输出的直流电转化为交流电。
优选地，该无线充电收纳盒还包括发射线圈盖板及散热板，设有所述无线充电发射模组的电路板上设有所述散热板，所述无线充电发射模组设置于所述收纳盒外壳的壳体与所述发射线圈盖板之间。
进一步地，所述收纳盒外壳包括通过一铰接件相互铰接的上壳体及下壳体，所述上壳体与所述下壳体盖合在一起时形成一收纳腔。
进一步地，所述发射线圈盖板、所述散热板及所述无线充电发射模组都设置于所述收纳盒的上壳体上，所述电池、所述逆变电路及所述电源电路都设置于所述收纳盒的下壳体上。
优选地，所述无线发射模组包括多个发射线圈，且每一所述发射线圈的电磁波发射方向互不相同。
优选地，该无线充电收纳盒还包括LED提示灯，所述LED提示灯设置于所述电源电路上。
另一方面，本发明还提出了一种无线充电耳机装置，包括无线充电耳机及如上所述的无线充电收纳盒，所述无线充电耳机内设有无线充电接收线圈、电池及电池充电电路；所述无线充电耳机可放置于所述无线充电收纳盒内，且所述无线充电收纳盒通过所述无线充电发射模组对所述无线充电耳机进行充电。
本发明技术方案通过在收纳盒内壁上添加无线充电发射模块来形成一种无线充电收纳盒。收纳盒可以用于放置带无线充电线圈无线耳机、手机等电子产品，在存储的同时，通过无发射线圈发射电磁波，对收纳盒内的电子产品进行无线充电。电子产品的放置于收纳盒内即可，无需固定于特定卡槽内，且可同时放置多个无线耳机，对多个耳机进行充电，方案简单有效。

为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做清楚、完整的描述。显然，以下描述的具体细节只是本发明的一部分实施例，本发明还能够以很多不同于在此描述的其他实施例来实现。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动的前提下，所获得的所有其他实施例，均属于本发明的保护范围。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。
在一实施例中，请参阅图1至图4所示，一种无线充电收纳盒，包括收纳盒外壳、电源电路9、无线充电发射模组4；电源电路9的输入端与电源接口连接，电源电路9的输出端与无线充电发射模组4的输入端连接；无线充电发射模组4的发射线圈设于收纳盒内壁上，无线充电发射模组4通过发射线圈发射电磁波。
本发明技术方案的收纳盒可以用于放置带无线充电线圈无线耳机、手机等电子产品，在存储的同时，通过无发射线圈发射电磁波，对收纳盒内的电子产品进行无线充电。电子产品的放置于收纳盒内即可，无需固定于特定卡槽内，且可同时放置多个无线耳机，对多个耳机进行充电，方案简单有效。
参照图5、图6及图7，，该无线充电收纳盒还包括电池11及逆变电路，电池11的输出端与逆变电路的输入端连接，逆变电路的输出端与电源电路9的输入端连接；逆变电路将电池11输出的直流电转化为交流电。通过内置的电池11及逆变器进行供电，可以在外出时进行充电，集收纳盒和充电宝于一身，便于短途旅行。本发明还设有控制电路，其用于控制变流、充电等。
具体地，该无线充电收纳盒还包括发射线圈盖板5及散热板3，设有无线充电发射模组4的电路板上设有散热板3，无线充电发射模组4设置于收纳盒外壳的壳体与发射线圈盖板5之间。
通过散热板3可以加强电路的散热性，增强电路的稳定性，保护电路的器件。而发射线圈可设置于发射线圈盖板5内，便于无线充电使用。
进一步地，收纳盒外壳包括通过一铰接件2相互铰接的上壳体1及下壳体12，上壳体1与下壳体12盖合在一起时形成一收纳腔。
进一步地，发射线圈盖板5、散热板3及无线充电发射模组4都设置于收纳盒的上壳体1上，电池11、逆变电路及电源电路9都设置于收纳盒的下壳体12上。将发射线圈和电池11分开，避免器件发热相互影响效率及稳定性，提升安全性。
具体地，无线发射模组包括多个发射线圈，且每一发射线圈的电磁波发射方向互不相同。
可以理解的时，通过多个方向互不相同的发射线圈，对放置角度不同无线充电耳机7进行充电，避免了无线充电耳机7的充电线圈与发射线圈之间夹角角度过大导致的无法充电或充电效率低的问题。当然，本方案也可使用一个较大公路的发射线圈进行充电，不以此为限制。
具体地，该无线充电收纳盒还包括LED提示灯，LED提示灯设置于电源电路9上。通过LED提升灯来提示电池11的电量或设备的充电状态。
从附图1、附图2、附图3中可知，LED灯上可以设置一个导光柱，该导光柱一端与LED提示灯相接，另一端延伸至下壳体12外，以此便于使用者在查看电量或充电状态。
另一方面，本发明还提出了一种无线充电耳机7装置，包括无线充电耳机7及如上的无线充电收纳盒，无线充电耳机7内设有无线充电接收线圈、电池11及电池11充电电路；无线充电耳机7可放置于无线充电收纳盒内，且无线充电收纳盒通过无线充电发射模组4对无线充电耳机7进行充电。
通过将设有无线充电接受线圈的无线充电耳机7放置于无线充电收纳盒内进行无线充电，不仅解决了现有的无线耳机充电仓由于接触不良导致的断充的问题,而且还解决了现有技术一套充电盒只能为一套耳机充电的问题，且耳机无需固定在设定好的卡槽里，灵活便捷。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形、替换及改进，这些都应涵盖在本发明的保护范围之内。因此，本发明专利的保护范围应以权利要求为准。
