所述塑胶件 10在结合处 13的第一外露表面 131与所述金属件 20在结合 处 13的第二外露表面 132平齐，所述第一外露表面 131与所述第二外露表面 132相接。
实施例 4
本实施例 4提供了一种塑胶件， 所述塑胶件作为电子设备电池壳体组件 的一部分，所述塑胶件与金属件结合形成用于容纳电子设备电池的容纳空间， 如图 9所示， 所述塑胶件具有一窗口 11及第一结合部 12, 所述金属件包括 片状部和第二结合部， 所述窗口被所述片状部覆盖， 所述第一结合部与所述 第二结合部配合。 如上文所述， 所述第二结合部包括以下至少一种结构： 翻边、 凸台、 翻 边孔， 或， 所述第一结合部为突起， 所述第二结合部为具有与所述突起配合 的小孔的弯折部。
所述塑胶件的材质为： PC、含有玻璃纤维的 PC,或含有玻璃纤维的 PPA 树脂； 所述薄膜的材质为 PET类塑料或 PC。 图 10、 11是本发明所述实例中将装饰片 40借助卡扣或背胶固定在机壳 上，盖住手机螺钉 50和防水薄膜 30的示意图。该装饰片 40不仅可以实现各 种外观效果的定制化， 还可以有效保护防水薄膜 30遭到损坏而失去 IPX7防 水功能。 釆用超薄装饰片， 可实现外观无螺钉和手机厚度降低。
通过本发明实施例的电子设备电池壳体组件、 塑胶金属组件、 以及塑胶 件， 提供了一种新的内置电池的保护设计方法， 该设计方法是电子设备结构 的一局部设计方案。 该方案利用金属件的特有属性， 可以减少空间占用， 增 强壳体强度实现对电池的跌落保护， 同时可以实现 IPX7 防水功能， 并可以 隐藏手机螺钉避免影响外观和降低手机整机厚度。
以上所述， 仅为本发明较佳的实施例， 但本发明的保护范围并不局限于 此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可轻易想 到的变化或替换， 都应涵盖在本发明的保护范围之内。 因此， 本发明的保护 范围应该以权利要求的保护范围为准。
工业实用 4生 釆用本发明实施例的技术方案， 可以减少空间占用， 增强壳体强度实现 对电池的跌落保护。
