以下结合附图对本发明的原理和特征进行描述， 所举实例只用于解释本 发明， 并非用于限定本发明的范围。
图 7为本发明手持移动设备壳的成型方法的流程示意图。 如图 7所示， 所述手持移动设备壳的成型方法包括以下步骤：
步骤 101 : 分别加工一个玻璃件和一个支撑件， 所述玻璃件作为手持移 动设备壳的视窗， 所述支撑件用于支撑玻璃件。
图 8为本发明玻璃件第一实施例的结构示意图。 该步骤中， 玻璃件的侧 壁被加工成直壁的结构， 如图 8所示， 即玻璃件的侧壁与玻璃件的上表面和 下表面相垂直。
图 9为本发明玻璃件第二实施例的结构示意图。 在该步骤中， 玻璃件的 侧壁被加工成裙边的结构， 如图 9所示， 所述具有裙边结构的侧壁由第一段 平面 a、第二段平面 b和弧面 c组成，所述第二段平面 b的一端和第一段平面 a相连，另一端和弧面 c相切；所述第一段平面 a的一端和第二段平面 b相连， 另一端和玻璃件的下表面相连； 所述弧面 c的一端和第二段平面 b相切， 另 一端和玻璃件的上表面相连。 所述第一段平面 a的倾斜度为 70° ~ 90。 , 所 述第一段平面 a沿其倾斜方向的长度为 0. 4毫米〜 0. 8毫米； 所述第二段平 面 b的倾斜度 e为 15 ° ~ 20。 ， 所述第二段平面 b沿其倾斜方向的长度为 0. 6毫米〜 1毫米；所述弧面 c半径 d为 0. 2毫米〜 0. 5毫米。在本实施例中， 所述第一段平面 a的倾斜度为 90° , 第二段平面 b的倾斜度为 18 ° , 所述 弧面 c半径 d为 0. 3毫米。
所述玻璃件的加工包括对玻璃依次进行母片切割、 仿型、 研磨、 抛光和 化学硬化即可制的图 8和图 9所示的玻璃件。
步骤 1 02 : 将玻璃件错开地放置于支撑件上， 即使支撑件的一端外露于 玻璃件。
当所述玻璃件的侧壁为直壁结构时， 在该步骤中， 先在玻璃件或者支撑 件上涂抹粘结剂， 再将玻璃件放置于支撑件上， 使玻璃件粘贴于支撑件上， 所述粘结剂为 3M 2665热固胶或者其它同类型产品。 或者还可以在所述玻璃 件和支撑件之间设置双面胶， 使玻璃件粘贴于支撑件上。 这里之所以通过粘 结剂或者双面胶将玻璃件固定于支撑件上，是因为这种情况的玻璃件厚度比 较小， 玻璃件只能加工成侧壁为直壁的结构， 如果不使用粘结剂或者双面胶 将玻璃件固定于支撑件的话， 当手持移动设备外壳遇到外力撞击时， 玻璃件 很可能从支撑件的表面脱离， 即从手持移动设备外壳上脱落造成损坏。
当所述玻璃件的侧壁为裙边结构时， 在该步骤中， 将玻璃件可以直接放 置于支撑件， 此时的玻璃件可以加工成裙边的结构， 这个时候的玻璃件相当 于具有一特殊的突出结构， 即倾斜度不同的第一段平面和第二段平面形成的 突出结构， 该结构可以很好地嵌在手持移动设备的壳体内， 即使当手持移动 设备外壳遇到外力撞击时， 玻璃件也不容易从支撑件的表面脱离， 即不容易 从手持移动设备外壳上脱落而造成损坏。
所述支撑件的形状不限， 其作用就是用于支撑玻璃件的， 只要保证在设 置时， 部分支撑件突出于玻璃件以外， 以便在后续的注塑成型过程中， 使支 撑件和玻璃件均与注塑成型件即手持移动设备壳体进行粘合。 步骤 103: 将放置了玻璃件的支撑件进行注塑成型， 形成包覆于玻璃件 和支撑件的手持移动设备壳体， 即制成手持移动设备壳。
所述步骤 1 03注塑成型过程中需要的各个参数及参数大小如表 1所示。
