An input apparatus for a vehicle includes: a knob rotatably disposed in a plate; a driving device allowing the knob to protrude from or move downward into the plate; and a switching mechanism movable disposed to surround an outer circumferential surface of the knob protruding from the plate and disposed along a circumference of the knob moved downward into the plate.

Proposed is an operation apparatus for a vehicle that improves visibility and interior aesthetics by appearing/disappearing mechanism of a button. The operation apparatus includes a panel, an operation module capable of moving, through an opening of the panel, between a first position and a second position spaced apart from each other in a front-back direction, a button placed on the operation module, a rotary link rotatably provided on an axis orthogonal to the front-back direction, a drive source for rotating the rotary link, and a cam mechanism having a guide path for inducing an angular motion of the rotary link and, thereby, moving the operation module to the first position or the second position.

A knob structure for an electromagnetic oven includes a knob switch assembly. The knob switch assembly consists of a sleeve button, a rotary encoder, a bracket of a display screen, and a control assembly. The knob switch assembly is connected to a printed circuit board through a through hole. A guide rib is disposed around a circumference of the through hole. The display screen with a protection assembly disposed outside is integrated with the knob switch assembly. The guide rib effectively prevents water from entering inside of the electromagnetic oven, lengthens a service life of the electromagnetic oven, and facilitates cleaning. The knob switch assembly integrated with the display screen realizes miniaturization and reduces a cost. The protection assembly ensures a display effect of the display screen.

Provided are an operating assembly and a household appliance. The operating assembly includes a first operating portion and a second operating portion. The first operating portion is at least partially disposed in the second operating portion. The second operating portion can be located at and move back and forth between a first position and a second position of the first operating portion. When the second operating portion is located at the first position, the second operating portion can rotate relative to the first operating portion to generate a first electric signal; when the second operating portion is located at the second position, the second operating portion can drive the first operating portion to rotate to generate a second electrical signal during the rotation of the first operating portion; and the first operating portion can be pressed to generate a third electric signal.

A control element for a household appliance includes an antenna for communicating with an external data source. The antenna can be formed by a cap which is connected to a housing of the control element and is retractable in relation to the housing by a retraction mechanism accommodated in the housing. A transmit/receive unit is supported by the cap and is connected to flexible conductor paths for conveying received or transmitted data.

A rotary knob assembly capable of up-and-down motion is provided. The rotary knob assembly includes a lower case with an oil damper; a rotary sleeve rotatably disposed in the lower case with a connecting hole; a slide cam that moves linearly with respect to the lower case with a pair of cam grooves and a sleeve hole; an elastic member disposed between the slide cam and the lower case; an up-and-down moving sleeve that moves up and down with respect to the rotary sleeve with a pair of up-and-down cams inserted in the pair of cam grooves of the slide cam; a rotary knob that is rotatably connected to the up-and-down moving sleeve; and an upper case connected to the lower case to limit vertical movement of the rotary knob, wherein a moving speed of the slide cam is controlled by the oil damper.

A single knob for controlling at least an audio input signal to produce up to fourteen distinct results, plus one quiescent state, through axial translational states corresponding to: the knob being translationally biased out, pushed in, or pushed in and held; and rotational states corresponding to: rotationally biased to a first position, turned clockwise, turned clockwise and held, turned counterclockwise, and turned clockwise and held, and combinations of those translational and rotational states. The single knob controller can be linked to a Bluetooth device for controlling such device. Some applications include automotive electronics and audio systems generally.
