如图 2、 6所示， 边框 100的两个侧边上各设有一个定位条 130， 定位条 130通过螺丝安装于边框 100上， 定位条 130相对于边框 100的反面凸起， 屏 幕 500位于两个定位条 130之间， 定位条 130抵靠屏幕 500的侧边， 将屏幕 500定位。 旋扣组件 200安装于定位条 130上， 利于旋扣组件 200将屏幕 500 夹紧在边框 100上。
如图 7所示， 后壳 600安装于屏幕 500的背面， 屏幕 500的背面设有螺 柱， 后壳 600通过螺丝安装于螺柱上。 后壳 600与屏幕 500之间构成芯片容 置室， 屏幕 500的配套芯片位于芯片容置室内， 保护芯片。 后壳 600的面积 小于屏幕 500的面积， 屏幕 500的背面没有被后壳 600覆盖的部分直接对外 散热， 散热效果好。
安装屏幕 500时， 安装步骤如图 4至 7所示顺序， 先把屏幕 500的定边 插入插槽 110内， 顺势将屏幕 500贴近边框 100， 屏幕 500挤压锁扣件 321使 其收缩至第一开孔 311内，使得屏幕 500通过锁扣件 321落入两个定位条 130 之间， 屏幕 500的正面贴靠于边框 100上。 此时， 支座 310穿过屏幕 500上 的安装孔 510， 并且支座 310设有锁扣件 321的一端从安装孔 510内伸出。在 屏幕 500通过锁扣件 321的位置后， 锁扣件 321从第一开孔 311内弹出， 锁 扣件 321的侧面抵靠屏幕 500的背面， 锁扣件 321将屏幕 500夹紧安装于边 框 100上。 然后， 旋动旋转体 210使旋转体 210远离转轴 230的一端锁紧屏 幕 500的背面， 此时， 压紧件 221从第二开孔 211内弹出， 将屏幕 500夹紧 安装于边框 100上。 之后将后壳 600安装于屏幕 500的背面， 使屏幕 500的 芯片位于屏幕 500与后壳 600之间的芯片容置室内， 保护芯片， 美化外观。
不限于此， 安装步骤也可以是： 旋扣组件预先不安装， 先通过定位条和 弹扣组件将屏幕定位在边框上， 再安装旋扣组件； 在安装旋扣组件时， 将转 轴 230穿过旋转体 210的通孔旋入定位条 130内， 通过调节转轴 230旋入定 位条 130的深度， 可以将压紧件 221与边框 100之间的间隙的宽度调节到与 屏幕 500厚度相当的宽度， 方便使旋扣组件牢固地压紧屏幕而不损坏屏幕。
在拆卸屏模组时， 转动旋转体 210使其松开屏幕， 将锁扣件 321挤压入 第一开孔 311内， 使屏幕 500从制作上脱出， 再将屏幕 500从插槽 110内取 出即可弯折拆卸， 可徒手操作， 无需专用工具， 方便快捷， 并且拆卸后的松 散零件数量少， 不易丢失。 需要维护屏幕芯片时， 将后壳从屏幕上拆下就可 以； 相比于传统的屏模组结构， 将后壳安装于边框上， 维护芯片时需要将整 个屏模组拆卸， 使用本实施例中的结构， 可以快速拆卸对芯片进行维护。 以上实施例的各技术特征可以进行任意的组合， 为使描述简洁， 未对上 述实施例中的各个技术特征所有可能的组合都进行描述， 然而， 只要这些技 术特征的组合不存在矛盾， 都应当认为是本说明书记载的范围。
以上实施例仅表达了本发明的几种实施方式， 其描述较为具体和详细， 但并不能因此而理解为对发明专利范围的限制。 应当指出的是， 对于本领域 的普通技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干变形 和改进， 这些都属于本发明的保护范围。 因此， 本发明专利的保护范围应以 所附权利要求为准。
