 附图说明
图1为本实用新型一种实施例的车载无线充电器的立体图。
图2为图1所示车载无线充电器的分解图。
 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。
为了解决无线充电过程中发热导致的充电效率低下的问题，本领域技术人员通常是尽一切可能的手段给无线充电设备进行散热。但是，单纯的给无线充电设备进行散热仍然无法解决发热导致的充电效率低下的问题。本申请人经过不断的实验及分析，发现智能设备如手机在无线充电过程中本身的发热问题才是导致充电效率低下问题的最大原因。
基于上述发现，本实用新型提供一种无线充电器99，请同时参阅图1和2，无线充电器99是为电子设备充电的车载无线充电器。该电子设备可以手机，平板电脑等。无线充电器99包括壳体10，夹持件20，固定件30，线圈模组40和电路板50。
壳体10大致呈长方体状，其包括对称设置的前盖12和后盖14，
故前盖12和后盖14均为半封闭腔体，前盖12和后盖14相互配合围成长方体状壳体10。
壳体10包括前面板120，后面板140，底板15，顶板16，第一侧板17和第二侧板18。前面板120和后面板140平行设置，且前面板120设置于第二盖体22的腔体底部，后面板140设置于第二本体21的腔体底部。底板15和顶板16平行设置。第一侧壁17和第二侧壁18平行设置。底板15，第一侧壁17，顶板16和第二侧壁18首尾依次垂直连接形成连接在前面板120和后面板140之间的侧壁。
夹持件20将该电子设备固定于壳体10上，其包括第一夹持部31，第二夹持部32和支撑部33。第一夹持部31和第二夹持部32对称设置于壳体10的相对两侧，且分别从第一侧壁17和第二侧壁18伸出壳体10外，将该电子设备夹持第一夹持部31和第二夹持部32之间。支撑部33从壳体10的底板15伸出，其支撑在该电子设备的底部。支撑部33，第一夹持部31和第二夹持部33三者配合将该电子设备固定于壳体10上，且该电子设备的壳体后盖依靠在壳体10的前面板120上。
固定件30将壳体10固定于车的空调出风口上。固定件30上设有万向转动结构，可以调节壳体10的角度从而固定在壳体10上的该电子设备的角度，方便用户使用该电子设备。
线圈模组40容置于壳体10内，其用于为放置在壳体10上的该电子设备充电。该电子设备会因为使用线圈模组30充电而产生热量使该电子设备的壳体后盖的温度升高。电路板50设置于线圈模组40和后面板140之间。
前面板120和后面板140靠近底板15和顶板16的位置均设有通孔190。当该电子设备放置在壳体10上采用无线充电器99充电时，车的空调出风口排出的风可以经由通孔190吹至该电子设备靠近壳体10的壳体后盖，使该电子设备在无线充电的过程中能快速降温。故，本实用新型提供的无线充电器散热性能比较好。
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。
