Rotating mechanism and electronic device with same

摘要

An exemplary rotating mechanism for rotating a second body relative to a first body is provided. The first body includes a pair of sidewalls, and the second body includes a pair of connecting arms. A first connecting piece rotatably connects one of the connecting arms to one of the sidewalls, and a second connecting piece rotatably connects the other connecting arm to the other sidewall. A resilient element connects the second connecting piece to a sidewall to provide a restoring force to the second connecting piece along a direction perpendicular to the sidewall. An angle positioner is fixed on the other sidewall and is sleeved on the first connecting piece. The angle positioner defines a positioning gap to engage with a pair of lugs extending from the first connecting piece for positioning a relative rotation angle between the first body and the second body.

1. A rotating mechanism for rotatably connecting a first body with a second body, the first body comprising a pair of sidewalls, the second body comprising a pair of connecting arms, the rotating mechanism comprising:
a first connecting piece rotatably connecting one of the connecting arms to one of the sidewalls; a second connecting piece rotatably connecting the other one of the connecting arms to the other one of the sidewalls; a resilient element connecting the second connecting piece with the sidewall and providing a restoring force to the second connecting piece along a direction perpendicular to the sidewall; and an angle positioner fixed on one of the sidewall and sleeved on the first connecting piece; wherein the angle positioner comprises a pair of angle positioning projections and defines a positioning gap between the angle positioning projection, the angle positioning projections are rotated about the first connecting piece to adjust an extending direction of positioning gap, the first connecting piece comprises a pair of lugs formed at an end of the first connecting piece, and the lugs are pulled into the angle positioning gap by the restoring force when the first connecting piece are rotated to a position where the lugs are aligned with the angle positioning gap.
