Operating elements fitted with movable actuating parts

Abstract

The operating element comprises: a movably mounted manually actuated actuating part (10), which can generate an actuating movement from a rest position along a linear actuating direction relative to the housing (14), and defines an actuating surface ( 12); reset means for resetting the actuating part (10) to a rest position; at least two gears (20) for converting the actuating motion into a rotatable transmission output shaft belonging to the respective gear (20) (22) and vice versa; a coupling device (30) capable of transferring the rotational activity of a transmission output shaft (22) of a gear (20) to the transmission output shaft (22) of at least one other gear (20) ), and vice versa, so that the actuation activities of at least all gears (20) are in the same direction, preferably in unison.

Description

technical field [0001] The invention relates to an operating element defining an actuating surface, especially suitable for use in a motor vehicle, comprising a movably mounted actuating part. Background technique [0002] Patent DE19911389A1 discloses a touch panel, on which two shafts with opposite angles are installed, and they can move relative to the casing. The touchpad is supported on four axle bearings, with two axle bearings aligned to form two axes parallel to the surface of the touchpad. This design structure allows the trackpad to move perpendicular to its surface, where the small axle bearing clearance also allows it to tilt slightly in the horizontal direction. [0003] Patent DE10341016A1 discloses a rotating disk / push disk with a circular actuating surface, and its axis perpendicular to the actuating surface can move linearly relative to the housing, and at this time the switching function will be triggered; while the circular The actuating surface can also...

AI Technical Summary

Problems solved by technology

[0005] Operating elements with actuating parts have relatively elongated actuating surfaces, but also have a fundamental problem: Due to the increasing expansion of the actuating surfaces, tolerances increasingly have a negative influence on the parallel alignment accuracy of the actuating surfaces during actuation

On the one hand, the resulting inclination is for aesthetic reasons, which is not what we want to see.

[0006] On the other hand, foreign bodies generally leak into the necessary gap between the orifice surrounding the actuating part and the actuating face, thereby increasing the risk of foreign bodies entering the lower area of ​​the actuating part, or at least sealing this gap difficult problem

Tilting also implies the risk of the mechanical support jamming and severe wear
