Abstract

An input apparatus for a vehicle includes: a housing mounted on the vehicle; a substrate disposed inside the housing; a push button device disposed in the housing to be pressed; a dial device arranged and configured to be rotated about the push button device, being non-peristaltic when the push button device is pressed, and maintained in a posture with respect to the housing, a first sensing device disposed on the substrate to sense pressing of the push button device; and a second sensing device disposed on the substrate to sense rotation of the dial device.

First claim

What is claimed is:

1. An input apparatus for a vehicle, comprising:
a housing mounted on the vehicle;
a substrate disposed inside the housing;
a push button disposed in the housing to be pressed;
a dial arranged and configured to be rotated about the push button, being non-peristaltic when the push button is pressed, and maintained in a posture with respect to the housing;
a first sensor disposed on the substrate to sense pressing of the push button; and
a second sensor disposed on the substrate to sense rotation of the dial,
wherein the push button includes a push button support disposed on the substrate and coupled to the housing;
wherein the dial includes a dial support surrounding a circumference of the push button support and rotatably disposed inside the housing,
wherein the input apparatus further comprises an elastic support to elastically support the rotation of the dial support about the housing, and
wherein the elastic support includes:
a cam groove including a first inclined surface and a second inclined surface connected with an end portion of the first inclined surface, the cam groove defined in the dial support;
a contact member disposed in a dial guide groove vertically formed at the housing to be guided to move vertically so that the contact member is able to contact the first inclined surface or the second inclined surface corresponding to a rotation direction of the dial support; and
an elastic member received inside the dial guide groove and a groove vertically formed at the contact member to elastically support the contact member such that the contact member elastically contacts the first inclined surface or the second inclined surface.

2. The input apparatus of claim 1 , wherein the push button further includes
a push button body coupled to the push button support movably in a vertical direction and exposed to an outside of the housing.

3. The input apparatus of claim 2 , wherein a guide rib is arranged at a lower portion of the push button body, and
wherein the push button support has a guide groove to movably receive the guide rib in the vertical direction.

4. The input apparatus of claim 2 , wherein a push protrusion is arranged at a lower end of the push button body;
wherein the first sensor includes a tact switch disposed under the push protrusion; and
wherein the pressing of the push button is sensed when the push protrusion pushes the tact switch.

5. The input apparatus of claim 2 , further comprising a push knob having a symbol and coupled to an upper end of the push button body,
wherein the push knob is non-peristaltic and has a posture maintained with respect to the housing, when the dial is rotated.

6. The input apparatus of claim 2 , wherein the dial further includes:
a dial body surrounding a circumference of the push button body, and disposed above the push button support,
wherein the dial support is coupled to the dial body to surround a circumference of the push button support and rotatably disposed inside the housing.

7. The input apparatus of claim 6 , wherein the dial support includes a magnet,
wherein the second sensor includes hall sensors spaced apart from each other in a circumferential direction of the dial support, and
wherein the hall sensors sense the rotation of the dial by sensing the magnet.

8. The input apparatus of claim 6 , further comprising a rotation restrictor to restrict the dial support from being rotated about the housing to a specific extent or more.

9. The input apparatus of claim 8 , wherein the rotation restrictor includes:
a locking groove defined in an outer circumferential surface of the dial support in a circumferential direction of the dial support; and
a stopper protrusion disposed on an inner surface of the housing, received in the locking groove, and selectively locked to one end or an opposite end of the locking groove corresponding to the rotation of the dial support.
