Portable electronic device

摘要

A portable electronic device includes a case, a push-push mechanism, and an element. The push-push mechanism includes a hollow column disposed in the case and having alternately arranged long grooves and short grooves, a pushing component having an inner end portion extending into the hollow column, a rotating component movably disposed in the hollow column, and a spring disposed for biasing the rotating component toward the pushing component. The pushing component is movable together with the element relative to the hollow column between a received position and an ejected position, where the positioning teeth are slidably and respectively received in the long grooves and the element is ejected out of the case.

主权项

1. A portable electronic device comprising:
a case formed with an opening; a push-push mechanism including:
a hollow column that is disposed in said case, and that has an inner surrounding surface, a plurality of angularly spaced-apart long grooves formed in said inner surrounding surface, and a plurality of short grooves formed in said inner surrounding surface, disposed alternately with said long grooves and shorter than said long grooves,a pushing component that has an outer end portion disposed in said case at a position adjacent to said opening, an inner end portion extending from said outer end portion into said hollow column, and a plurality of first engaging teeth disposed annularly on said inner end portion,a rotating component that is movably disposed in said hollow column and that includes a ring member, a plurality of positioning teeth protruding radially and outwardly from an external surface of said ring member, and a plurality of second engaging teeth disposed annularly on said ring member and abutting against said first engaging teeth, anda spring that is disposed in said hollow column and that biases said rotating component toward said pushing component; andan element that is connected to said outer end portion of said pushing component;wherein said pushing component is capable of moving relative to said hollow column between a received position, where said positioning teeth engage respectively with said short grooves and said element is located within said case, and an ejected position, where said positioning teeth are slidably and respectively received in said long grooves and said element is ejected out of said case through said opening.
