在本实施例中， 所述前框 11和背板 13通过螺釘 16固定连接，所述前框 11 上设有螺釘柱 113, 所述背板 13上设有通孔 131 , 螺釘 16穿过所述通孔 131与 螺釘柱 113连接， 从而把前框 11和背板 13固定连接， 所述中框 12上还设有避 让螺釘 16和螺釘柱 113的通孔 121 ,所述中框 12夹紧在前框 11和背板 13之间。 本发明利用螺釘连接前框、 背板和中框， 结构筒单， 实现容易， 由于螺釘 16是 设置在背板 13后方， 不易引起人们的关注。
在本实施例中， 所述前框 11和背板 13的外围尺寸均小于中框 12的外围尺 寸， 所述前框 11容置在中框 12内侧， 所述背板 13也容置在中框 12内侧， 这 样中框 12的外侧是一个平面， 光滑， 具有良好握持手感， 而且更美观。
本发明所述前框 11和中框 12均为塑料材质， 并在同一个模具 2中注塑成 型， 如图 3所示， 所述模具 2包括构件单元型腔 21和中框型腔 22, 所述构件单 元型腔 21环绕分布在中框型腔 22外侧， 所述模具 2可以同时成型前框的四个 构件单元和中框， 由于本发明对中框的强度要求较高， 一般应选择一体式结构， 即通过模具一次制作成型， 所以中框的模具尺寸较大， 本发明利用前框的构件 单元和中框尺寸相近的特点， 把四个构件单元型腔 21布置在中框型腔 22的四 周， 由于构件单元型腔 21的宽度较窄， 这样模具 2尺寸稍微增大就可以容置下 构件单元型腔 21 , 可以大幅降低模具成本， 另外本发明所述前框和中框采用极 冷极热工艺注塑成型， 可以制作出非常光洁的表面， 从而起到装饰作用。
如图 4所示， 为本发明所述前框 11的另一实施例， 前框 11包括四个边框 112, 其中两个边框 112相连接组成一个 L形构件单元 111 , 另外两个边框 112 相连接组成另一个 L形构件单元 111 , 如图 5所示， 为本发明制作上述前框 11 和中框 12的模具 2, 模具 2包括构件单元型腔 21和中框型腔 22, 所述构件单 元型腔 21环绕分布在中框型腔 22外侧， 由于充分利用了前框构件单元和中框 尺寸相近的特点， 使得模具制作成本得到降低。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干筒单推演或替 换， 都应当视为属于本发明的保护范围。
