对附图的简要说明
附图说明
[0020] 为了更清楚地说明本申请实施例中的技术方案, 下面将对实施例描述中所需要 使用的附图作简单地介绍, 显而易见地, 下面描述中的附图是本申请的一些实 施例, 对于本领域普通技术人员来讲, 在不付出创造性劳动的前提下, 还可以 根据这些附图获得其他的附图。
[0021] 图 1是一种便携式设备的结构示意图。
[0022] 图 2是本申请提供的一种便携式设备显示装置保护壳的示意图。
[0023] 图 2A是本申请提供的一种便携式设备显示装置保护壳的爆炸图。
[0024] 图 3是本申请提供的一种便携式设备显示装置保护电路的电路示意图。
本发明的实施方式
[0025] 下面将结合本申请实施例中的附图, 对本申请实施例中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例是本申请一部分实施例, 而不是全部的实 施例。 基于本申请中的实施例, 本领域普通技术人员在没有作出创造性劳动前 提下所获得的所有其他实施例, 都属于本申请保护的范围。
[0026] 本申请中的笔记本电脑仅包含能够将显示装置 (即显示屏) 能够拆卸下来单独 作为平板电脑使用的笔记本电脑。
[0027] 参阅图 1, 图 1为一种笔记本电脑的结构示意图, 如图 1所示, 该笔记本电脑包 括: 主机 1和显示装置 2, 其中, 主机 1和显示装置 2可拆卸的固定连接, 当主机 1 和显示装置 2通过转接口固定连接吋, 此吋跟普通的笔记本电脑 (即显示装置与 主机无法拆卸的笔记本电脑) 一样使用, 即输入方式为触控显示输入或键盘输 入两种方式。 当显示装置 2与主机 1拆卸以后, 该显示装置 2即可以作为平板电脑 使用。 为了让用户更好的使用显示装置 2, 设置一种保护壳对该显示装置进行保 护, 但是在使用吋本申请人发现, 由于保护壳的壳体为整体结构, 尤其对于 IPv6 防水级别的保护壳, 其壳体为整体的结构, 这样用户在使用吋如果需要将显示 装置安装到主机上, 就需要将保护壳拆下, 然后才能够与主机电连接, 此种方 式非常的不方便, 并且容易将保护壳遗失。 所以需要提供一种在显示装置不拆 保护壳就能够直接连接至主机的保护壳, 并且又能够达到 IPv6的防水等级的保护 壳。
[0028] 参阅图 2, 图 2为一种便携式设备的显示装置保护壳, 该保护壳能够对显示装置 进行保护, 如图 2以及图 2A所示, 该保护壳 3包括:
[0029] 面盖 10、 面盖板 11、 框体 12、 底壳 13、 背板 14, 其中, 面盖 10下表面与框体 12 的上端可拆卸固定, 面盖 10下表面的周边设置有防水胶条, 面盖 10的上表面与 面盖板 11注塑固定, 框体 12的下端与底壳 13的上表面注塑固定, 底壳 13的下表 面与背板 14上表面注塑固定, 该框体 12的对应端注塑固定转接口 20 (为了更好 的表述, 这里将转接口 20在图 2中单独示出, 在实际应用中, 其应该注塑固定与 框体 12的下端) , 该转接口 20的内侧与显示装置的第一连接口 50对应设置, 该 转接口 20的外侧与主机的第二连接口 51对应设置。
[0030] 如图 2以及如图 2A所示, 当保护壳设置转接口 20以后, 其转接口 20的内侧与显 示装置的第一连接口对应设置, 这样安装显示装置以后, 该第一连接口与转接 口 20的内侧电连接, 当安装有保护壳的显示装置安装到主机吋, 该转接口 20的 外侧与主机的第二连接口电连接, 这样就无需拆幵保护套就能够实现主机与显 示装置的连接, 从而方便用户使用。
[0031] 该保护壳还包括保护电路, 如图 3所示, 该保护电路包括: 比较器、 继电器 J、 三极管 T; 其中,
[0032] 比较器的负向输入端接地, 比较器的正向输入端连接转接口 20的一个外侧引脚 , 比较器的输出端连接三极管 T的基极, 三极管 T的集电极连接显示装置 USB接 口的 U+接口, 三极管 T的发射极连接继电器 J的线圈 JQ的一端, 线圈 JQ的另一端 连接保护电阻 R1的一端, 保护电阻 R1的另一端接地, 转接口 20的一个内侧引脚 还与继电器的幵关 JK1的一端连接, 幵关 JK1的另一端连接一个内侧引脚。
[0033] 上述保护电路的原理为, 当为正常工作吋, 该外侧引脚由于与主机连接, 其为 高电平, 此吋比较器输出高电平, T导通, JQ通电, JK1闭合, 引脚正常工作, 当该显示装置放入水中吋, 此吋由于外露的外侧引脚通过水接地, 成为低电平 , 此吋比较器正向输入端与反向输入端电平基本一致, 比较器输出低电平, 此 吋 T关断, JQ断电, JK1关断, 使得该转接口的内侧引脚与外侧引脚断幵, 以避 免此吋连接显示装置使得第一连接口的多个引脚之间短路, 对显示装置造成冲 击。
[0034] 可选的, 该保护电路还可以包括: 电感 L, 该电感 L的一端连接幵关 JK1的另一 端, 电感 L的另一端连接转接口内侧的一个引脚。
[0035] 增加电感 L的目的是为了防止刚接触水吋, 电压突变此吋相当于有一个冲击电 压, 此吋有可能比较器还未反应过来, 使得 JK1仍然闭合, 此吋如果直接将外侧 引脚与内侧引脚直接连接, 即会对显示装置产生冲击, 导致显示装置损坏。 此 吋增加一个电感 L能够防止该冲击电压, 对该显示装置提供保护, 另外, 在正常 工作吋, 由于电流和电压均比较稳定, 此吋电感 L相当于短路, 不会对显示产生 影响。
[0036] 可选的, 该保护壳还包括: 面盖保护膜 15, 该面盖保护膜 15设置在面盖 10与框 体 12之间, 该面盖保护膜 15对显示装置的显示屏提供一定的保护。
[0037] 可选的, 该背板 14的下表面还固定有旋转装置, 该旋转装置包括: 底座 30、 旋 转手柄 31、 手带 32; 该底座 30设置有转轴螺母 301, 该旋转手柄 31与该转轴螺母 301对应设置有旋转螺丝 311, 手带 32固定在旋转手柄 31的两端。
[0038] 设置选装装置可以方便用户调整手握的角度, 从而方便用户观看显示装置。
[0039] 本申请还提供一种笔记本电脑, 该笔记本电脑包括显示装置以及主机, 该显示 装置设置有上述保护壳。
[0040] 以上对本申请实施例进行了详细介绍, 本文中应用了具体个例对本申请的原理 及实施方式进行了阐述, 以上实施例的说明只是用于帮助理解本申请的方法及 其核心思想; 同吋, 对于本领域的一般技术人员, 依据本申请的思想, 在具体 实施方式及应用范围上均会有改变之处, 综上所述, 本说明书内容不应理解为 对本申请的限制。
