Description

Long life input device for operating device Technical Field The present invention relates to an input device for operating a device, wherein the input device is designed for long-term use, and wherein actuation of the input device by a user along an actuation axis is considered to be a pleasant and high quality touch. The invention also relates to an operation device with the input device. Background The support and guiding of the input device, in particular of the keys, is usually achieved by mechanical elements, such as coupling elements, also called stabilizer bars, in order to allow a stroke movement of the actuating elements of the input device in a uniform manner or substantially parallel to the base plate. By way of example, in the US patent application US 2014/0190810A1, an above-mentioned input device, in particular a key, for an operating device, in particular for a keyboard, is disclosed. In this document, fig. 8A and 8B disclose an embodiment of an input device with a magnetic return mechanism. The input device includes a key cap, a base, and a magnetic return mechanism. The magnetic return mechanism includes a first magnetic component and a second magnetic component. The key cap and the base are movably coupled to each other by a coupling element (also referred to as a stabilizer bar). In order to make the dual characteristics of the stabilizer bar easier to understand, the key cap shown in transparent form in fig. 8A illustrates the use of the stabilizer bar. The stabilizer bar includes a protrusion slidably engaged in a recess in the key cap. The hooking engagement of the protrusion in the recess allows translational movement. Furthermore, the stabilizer bar comprises protrusions received by recesses in the base, which protrusions establish a pivotable connection between the base and the stabilizer bar. However, pivotable connections cause problems. The free pivot space available for the stabilizer bar may thus for example lead to tilting of the bar and if the key is actuated further there is a risk of breakage due to the load, with the result that the service life of the input device is disadvantageously short. Disclosure of Invention It is therefore the basic object of the present invention, starting from the above-mentioned prior art, to propose an input device and an operating device with such an input device, which have a long service life, contain low-cost components and are capable of providing high-value haptic feedback to the user. According to the invention, this object is achieved by the features of the independent claims. Advantageous developments of the invention are given in the dependent claims. Thus, an input device for an operating device of a motor vehicle according to the present invention comprises: An actuating element having a first receiving portion, A base plate having a second receiving portion, A coupling element having a first coupling part and a second coupling part, wherein the first coupling part is supported in a first receptacle, the second coupling part is supported in a second receptacle, As a result, when a pressure is exerted on the actuating element, the actuating element can be moved along the actuating axis relative to the base plate via the coupling element, wherein the first and second receptacles are configured such that a rotational and/or translational movement of the first and second coupling parts in the respective receptacles is possible, It is characterized in that the method comprises the steps of, The first coupling part and the second coupling part are supported in the respective receptacles without play along the actuation axis. The first receptacle and the second receptacle are preferably configured such that a rotational movement of one coupling part and a translational movement of the other coupling part can be carried out in the respective receptacles. The operating device with the above-described input device is also in accordance with the invention. The basic concept of the invention is thus an input device with an actuation element that is movable relative to a substrate. The actuating element is movably coupled to the base plate by a coupling element. The core of the invention is that the coupling element can be translated on one side and rotationally moved on the other side relative to the actuating element and the base plate, respectively. The interface between the coupling element and the corresponding coupled mechanism (i.e. the actuation element and the base plate, respectively) has a gapless design, irrespective of the temperature and the number of mechanical elements. In this mechanism, a fixed static support is provided for the coupling element in one side in the direction of the stroke movement along the actuation axis, to ensure that no losses, tilting or the like are felt or introduced during actuation due to element yielding (yielding), thus increasing the lifetime of the component. Since the frictional force acts on a sm
