Abstract

A dial-type shifting control apparatus of vehicles may include a dial bezel and an upper cover integrated into a single body to be rotated together when a dial is rotated, obviating formation of an operation gap between the dial bezel and the upper cover to prevent foreign substances from entering through the operation gap, and a button guide disposed under an upper cover attenuates an impact occurring when a P-gear button is returned, and thus to prevent noise, caused by striking of the upper cover when the P-gear button is returned, from being transmitted to the interior of a vehicle.

First claim

What is claimed is:

1. A shifting control apparatus of vehicles, the shifting control apparatus comprising:
an upper cover having a button exposure hole formed through the upper cover;
a dial bezel extending in a circumferential direction of the upper cover and integrated with the upper cover to form a single solid body without a gap between the dial bezel and the upper cover along a circumference of the upper cover, wherein the upper cover and the dial bezel are integrated into the single solid body by a dual shot injection molding;
a dial disposed on a circumference of the dial bezel and fastened to the dial bezel to be rotated simultaneously with the dial bezel;
a dial housing extending from and integrated with a lower portion of the dial and mounted on a rotation shaft of a main housing;
a button housing disposed in the dial housing and fixedly mounted on a stationary shaft of the main housing; and
a button guide fixedly fastened into the button housing to guide a button in an elevation direction thereof,
wherein the button is disposed on the button guide so that an impact generated when the button is returned to an original position thereof is absorbed, and the button is exposed outside of the upper cover through the button exposure hole of the upper cover, and
wherein the button guide comprises:
an external ring fastened to the button housing;
an internal ring formed inside the external ring so that a body of the button is elevated in the internal ring;
guide holes, wherein guide blocks of the button located in the guide holes are selectively elevated along the guide holes; and
an impact absorption member formed on an upper end portion of an internal ring in an axial direction of the guide holes to absorb the impact caused by return of the guide blocks of the button.

2. The shifting control apparatus of claim 1 , wherein first locking holes are formed in a lower portion of the dial bezel, and first hooks configured to be fastened into the first locking holes are formed on an internal surface of the dial.

3. The shifting control apparatus of claim 1 , wherein second locking holes are formed through a bottom surface of the dial housing, and second hooks configured to be fastened into the second locking holes are formed on an upper portion of the rotation shaft.

4. The shifting control apparatus of claim 1 , further including:
stoppers attached to an upper portion of the guide blocks of the button, wherein the impact absorption member absorbs the impact caused by return of the stoppers.

5. The shifting control apparatus of claim 1 ,
wherein the internal ring is offset from the external ring inwards with a predetermined length so that the body of the button is located in the internal ring to be elevated,
wherein the button guide further includes a connector connecting the external ring to the internal ring, and
wherein the guide holes are formed in the connector.

6. The shifting control apparatus of claim 1 , wherein third locking holes are formed in an internal surface of the button housing, and third hooks configured to be fastened to the third locking holes are formed on an external surface of the button guide.
