    • The electronic device includes a first cover, a second cover, a light guiding element, and a PCB. A first blocking rib is formed on a bottom of the first cover. A retaining panel extends from the bottom and includes a hook at a distal end thereof. The second cover includes a second blocking rib. The PCB is positioned between the two covers. A light source is mounted on the PCB. A light guiding element includes a flat panel and two sidewalls extending from the flat panel. The hook engages with the end surface of the first sidewall. The first blocking rib and the retaining panel abut against opposite sides of the light guiding element. The second blocking rib abuts against the end surface of the second sidewall. The light guiding element is coupled to the light source and configured to transmit the light from the light source.
    • 该电子设备包括第一盖,第二盖,导光元件和PCB。 在第一盖的底部上形成第一阻挡肋。 保持板从底部延伸并且在其远端包括钩。 第二盖包括第二阻挡肋。 PCB位于两个盖子之间。 光源安装在PCB上。 导光元件包括平板和从平板延伸的两个侧壁。 钩与第一侧壁的端表面接合。 第一阻挡肋和保持板抵靠导光元件的相对侧。 第二阻挡肋抵靠第二侧壁的端面。 光引导元件耦合到光源并且被配置为透射来自光源的光。
