Abstract

A button indicator and a light guiding ring assembly are provided. The button indicator includes a button cover and a light guiding ring. The button cover has a cover body, retaining walls and hooks. The cover body has a top surface and a bottom surface. The retaining walls and the hooks protruded from the bottom surface are disposed around the cover body. The light guiding ring sleeved on the button cover has a ring body, elastic arms, a sliding matching groove and light guiding portions. The ring body has an inner surface with the elastic arms and the sliding matching groove disposing thereon and an outer surface with the light guiding portions locating thereon. The retaining walls abut against the inner surface of the ring body, and the hooks move along and snap the sliding matching groove. The elastic arms abut against the bottom surface of the cover body.

Claims

1. A button indicator, comprising:

a button cover, having a cover body, a plurality of retaining walls and a plurality of hooks, the cover body having a top surface and a bottom surface, wherein the top surface and the bottom surface are oppositely disposed, the retaining walls and the hooks are protruded from the bottom surface, and the retaining walls and the hooks are disposed around the cover body; and

a light guiding ring, assembled with the button cover, having a ring body, a plurality of elastic arms, a sliding matching groove and a plurality of light guiding portions, wherein the ring body has an inner surface and an outer surface, the elastic arms and the sliding matching groove are disposed on the inner surface, the light guiding portions are located on the outer surface, the retaining walls are adapted to abut the inner surface of the ring body, and the hooks are adapted to move along and hooked to the sliding matching groove, and the elastic arms are adapted to abut the bottom surface of the cover body.

2. The button indicator of claim 1, wherein the elastic arms are protruded from the inner surface of the ring body toward a center of the ring body, and extend along an axial direction of the ring body toward the button cover.

3. The button indicator according to claim 1, wherein the light guiding portions are grooves, and an arc angle of the groove ranges from 91 degrees to 101 degrees.
