Stepless rotating knob module and electronic device having the same

摘要

A stepless rotating knob module includes a supporting frame, a rotating disk, a suspending assembly, an encoding switch and a transferring element. The support frame has a front wall, a top wall and a bottom wall. The front wall is formed with a through hole. The rotating disk is disposed between the top wall and the bottom wall and is partially exposed outside the through hole. The suspending assembly passes through the rotating disk and is fixed to the bottom wall, so that the rotating disk is rotatably mounted on the suspending screw. The encoding switch is fixed to the bottom wall of the supporting frame and has a rotating rod. The transferring element is fixedly disposed on the bottom of the rotating disk fixed to the bottom of the transferring element. The present disclosure also provides an electronic device having stepless rotating knob module.

主权项

1. A stepless rotating knob module, comprising:
a supporting frame, having a front wall, a top wall, and a bottom wall, wherein the top wall and the bottom wall are respectively extending from a top edge and a bottom edge of the front wall, the front wall is formed with a front opening; a rotating disk, disposed between the top wall and the bottom wall of the supporting frame, and partially exposed outside the front opening; a suspending assembly, passing through the rotating disk from a bottom surface of the rotating disk, wherein the suspending assembly has a top end fixed to the top wall and a bottom end arranged above the bottom wall of the supporting frame, wherein the rotating disk is rotatably disposed on the bottom end of the suspending assembly, thereby the rotating disk is suspended from the top wall of the supporting frame; an encoding switch, fixedly connected to the bottom wall of the supporting frame, wherein the encoding switch has a rotary encoder for outputting an adjustment signal and a rotating rod extended toward the top wall; wherein the rotating rod is rotatable and substantially perpendicularly connected the rotary encoder; a transferring element, fixedly disposed on the center of the bottom surface of the rotating disk, made of vibration-absorbable material, wherein a top end of the rotating rod of the encoding switch is fixedly wedged in the transferring element; and a lower rotating supporter passing through and fixed to the bottom wall of the supporting frame, wherein the lower rotating supporter fixes the encoding switch to the bottom wall; wherein the lower rotating supporter includes a base board fixed to the bottom wall of the supporting frame, and an annular portion upwardly protruding from the base board; wherein the bottom wall of the supporting frame is formed with a bottom hole, the annular portion is passing through the bottom hole, wherein the lower rotating supporter has a plurality of bumps formed on a top surface thereof and contacting with the bottom surface of the rotating disk; wherein the base board is formed with a rod hole, the encoding switch has a screwing cylinder-portion disposed at a periphery of the rotating rod, the screwing cylinder-portion passes through the rod hole and fixed to the base board, wherein the bumps are formed on the top edge of the annular portion.
