Description

无线充电器 技术领域
本发明涉及无线充电的配件领域，特别涉及一种具有散热功能的无线充电器。
 背景技术
无线充电器在充电时电路板和线圈发热量较大，手机充电时也会发热，若热量不能及时散出，聚集后使充电部位温度持续升高，通常手机在达到一定温度时会自动断电，以保护电池，从而使充电不能持续进行。
 技术问题
有鉴于此，本发明提出一种具有散热功能的无线充电器。
 技术解决方案
一种无线充电器，其特征在于，包括壳体，设置于该壳体内的无线充电模组及散热模块，所述无线充电模块与散热模块沿所述壳体的水平方向间隔排布，所述壳体设置通风部，用于将壳体内的热量排到壳体外。所述壳体包括上盖、下盖以及连接所述上盖和下盖的侧壁，所述上盖、下盖及侧壁三者中至少一个上设置所述通风部。
在一实施例中，所述上盖与所述边框一次成型，形成一体结构，所述下盖为一片式金属结构。
在一实施例中，所述下盖与所述边框一次成型，形成一体结构。
在一实施例中，所述线圈为两个，可同时给两个个电子设备充电。
在一个实施例中，所述上盖上设置有LED显示屏，可以显示环境温度、湿度及时间等。
在一实施例中，所线圈模块与所述电路板平行设置于所述容置腔内，均与下盖相接触。
 有益效果
综上所述，本发明提供一种具有散热功能的无线充电器，在充电器本体的侧壁上设置散热孔，使得充电器本体的内部通过散热孔和间隙与外界空气对流，从而达到散热的目的。此外，本发明还在上盖上设置散热孔，进一步对无线充电器进行散热，使得充电器内部与外界空气充分流通，从而充分散热，不会引起热量集中，从而降低充电时手机电池的温度，使充电持续进行。
 附图说明
图1为本发明的无线充电器在一实施例的分散结构示意图。
图2为图1中的无线充电器在一个角度的立体结构示意图。
图3为本发明的无线充电器在另一实施例的分散结构示意图。
图4为图3中的无线充电器在一个角度的立体结构示意图。
 本发明的实施方式
在详细描述实施例之前，应该理解的是，本发明不限于本申请中下文或附图中所描述的详细结构或元件排布。本发明可为其它方式实现的实施例。而且，应当理解，本文所使用的措辞及术语仅仅用作描述用途，不应作限定性解释。本文所使用的“包括”、“包含”、“具有”等类似措辞意为包含其后所列出之事项、其等同物及其它附加事项。特别是，当描述“一个某元件”时，本发明并不限定该元件的数量为一个，也可以包括多个。
如图1-2所示，一种无线充电器10，包括壳体11，设置于该壳体11内的无线充电模块16及散热模块15，所述无线充电模块16与所述散热模块15沿所述壳体的水平方向间隔排布，所述壳体11包括上盖12、下盖14以及连接所述上盖和下盖的侧壁13，所述侧壁上设置通风部131，所述通风部131由若干个条形通风孔组成，用于将壳体内部的热量带到壳体外。
本实施例中，所述散热模块15为风扇模块，所述上盖12与所述散热模块15对应的位置还设置有一通风部121，所述通风部121由若干个竖条形通风孔形成，当所述风扇模块15工作时，风可以从所述侧壁13的通风孔131进来，通过风扇，从位于所述上盖12的通风孔121出去，从而带走热量。可以理解，所述通风部121的通风孔形状不限，例如可以为多个圆形小孔排列成如图1所示的圆形图案，或者排列成方形或其他形状的图案。总之，只要设置与风扇模块15对应的通孔结构便可。
所述无线充电模块16包括线圈模块161及电路板162，所述电路板162为中间镂空的环形结构，所述线圈模块161嵌设于镂空结构中，与环形电路板162基本上排布于一个水平面内，且线圈模块161与电路板162电连接，例如通过导线电连接。
所述壳体11呈扁平椭圆状，所述无线充电模块16位于所述壳体11长度方向的一侧，所述散热模块15位于所述壳体11长度方向的另一侧，当具备无线充电功能的电子设备贴附于所述上盖11表面时，所述无线充电模块16可自动感应并为该电子设备充电。
所述下盖14为导热材质，例如为导热金属片并直接与侧壁13的下边框接合在一起，无线充电模块16的线圈模块161及电路板162均直接固定在下盖14上，其工作过程发出的热量壳快速传递至下盖14，并通过下盖14散发到外界。在其他实施方式中，所述侧壁13与所述下盖14可以为一次成型的一体结构。
应当理解的是，将散热结构实施为散热孔121、131仅为本发明的一种实施方式，在其他实施例中，根据实际设计需求，散热结构也可以设置为其他结构，例如散热槽等，只要能够使得充电器壳体11内部与外界有空气对流即可，本实施例中仅设置一个感应线圈161，在其他实施方式中，感应线圈可以是2个或多个，从而可同时为多个电子设备充电。
如图3-4的实施例中，所述无线充电器20的结构相似，在结构中，所述上盖22上设置一LED显示屏221，可以显示无线充电器表面的温度、环境湿度及时间等信息。
所述侧壁23与所述上盖21为一次成型的一体结构。
综上所述，本发明提供一种具有散热功能的无线充电器，在充电器本体的侧壁上设置散热孔，使得充电器本体的内部通过散热孔和间隙与外界空气对流，从而达到散热的目的。此外，本发明还在上盖上设置散热孔，进一步对无线充电器进行散热，使得充电器内部与外界空气充分流通，从而充分散热，不会引起热量集中，从而降低充电时手机电池的温度，使充电持续进行。
本文所描述的概念在不偏离其精神和特性的情况下可以实施成其它形式。所公开的具体实施例应被视为例示性而不是限制性的。因此，本发明的范围是由所附的权利要求，而不是根据之前的这些描述进行确定。在权利要求的字面意义及等同范围内的任何改变都应属于这些权利要求的范围。
