Description

Title: "Haptikerzeugung for a pressure-tilt button"

The invention relates generally to a control element with a tiltable from a rest position that is pivotable operating lever, in particular for use in a motor vehicle. Typically, the operating lever is mounted a ball joint, and there are additional means provided to effect a locking in the resting position. These designs have the disadvantage of not precisely defined in the rule rest. Respectively, the known controls play in the rest position of which is subject to wear.

Against this background, the present invention has the object of providing a control element with precise rest position, which is particularly subject to less wear. This object is achieved by an operating element according to claim 1 and the independent claim. Advantageous embodiments are the subject matter of the dependent claims. It should be noted that the features listed individually in the claims can be combined in any technologically meaningful way with each other and show further embodiments of the invention. The description characterizes and specifies the invention further.

The control element according to the invention for a motor vehicle comprises: a tiltable operating lever is mounted and means for returning the operating lever in a rest position. The invention is not restricted to a special operating lever. This concerns the design of the operating lever, so that, for example, provided with an additional control knob in one embodiment, at its free end facing the operator. On the other hand, the invention is also not limited to particular or specific number of switching and control functionality. For example, additional degrees of freedom may be provided, which also is assigned then an additional switching and control functionality in addition to the tilting movement, which is associated with specific switching and control functionality. Further operating element of the invention is not limited in the manner in which the position of the operating element is detected. For example, may be provided for position detection of electromechanical, optically or magnetically operating means or sensors.

According to the invention the storage of the operating lever at least one tilting edge, around which the operating lever is tilted from the rest position. Thereby a precise and defined transition from the rest position is reached. A rest position game is at least minimized. The solution is inexpensive, since the storage itself defines the rest position and thus no need for additional locking means. Characterized in that the rest position is only left with tilting over the tilting edge by applying a corresponding leverage, the restoring force is a comparatively abruptly. It is possible even at low Kippausschlag comparatively high restoring forces, to apply what contributes to improved provision in the rest position. Moreover, the pivotal movement of the operating lever is defined by the rocking edge, whereby a setting is unnecessary. By means of location and configuration of the rocking edge can be easily not only the restoring force and optionally interpret the haptics constructive, but also minimize the kickback noise.

In another function, such as a forming functions of the operating lever, the degrees of freedom are not only better tactile perceivable by the inventive design, thus operating errors are avoided, it can be as well be taken to ensure that even with oblique or off-center force the push functionality instead of Kippfunktionalität preferred is triggered. Thus, the operating safety is increased.

Preferably, the rocking edge is spaced apart from the central axis of the operating lever, so this does not intersect. By displacement of the tilting axis, not only rotation but also a reciprocating movement or a displacement movement in a direction perpendicular thereto of the operating lever and optionally the attached operating knob is carried out. The additional lifting movement of the Verschwenkmaß of the operating lever can be increased, since the button is no longer or at least not as early collides by its lifting movement to the housing or a diaphragm surrounding the control element. This is particularly advantageous if the dimension of the maximum projection of the operating knob or lever about the visor is required by law or by standardization. Reference is made to the so-called head impact criteria. In the later described preferred use of permanent magnet pairs for the restitution and / or Haptikerzeugung this lifting movement is used to generate an additional relative movement of the magnet in the direction of the stroke movement. Characterized the dependent deflection of the operating lever resilience or haptic can be "modulated" by this additional direction of movement.

Preferably, the operating lever from the rest position in a plurality of directions and tiltable for each direction a rocking edge is provided. For example, four pairs of parallel rocking edges are provided. the bearing is preferably designed such that a flat support of the operating lever is achieved in the rest position. For example, the operating lever forms a flat surface which abuts against a flat mounting surface, for example, the housing of the operating element in the rest position of the operating lever.

The means for returning to the rest position may for example have one or more springs. According to one further preferred embodiment, these means comprise at least a pair of first relatively movable permanent magnets. in the rest position respectively opposite poles of the first permanent magnets are preferably arranged adjacent to the next, wherein an air gap is formed between the first magnets. For example, one of the pair of first permanent magnets to the control lever is connected rigidly and the other rigidly connected to the control lever support and thus the movement of the operating lever causes relative movement between the magnets of said pair.

In a preferred embodiment, the first permanent magnets cause also a holding function of the operating lever. For example, they cause in the rest position of a control lever-side flat bearing surface is pressed against a flat, connected to the housing or formed thereon receiving surface.

According to a further advantageous embodiment, means are also provided for Haptikerzeugung, which also comprise at least a pair of second permanent magnets. in the rest position respectively opposite poles of the second permanent magnets are preferably also arranged next adjacent. For example, one of the second permanent magnet with the control lever is connected rigidly and the other rigidly connected to the operating lever for storage and thus causes the movement of the operating lever, a relative movement between the magnets of said pair. Moving said second permanent magnets, for example, parallel to the direction of polarity ensures as "snap" to be referred to feel.

Preferably, the operating lever is in two orthogonal more preferably in four directions from the rest position tilted. According to a further embodiment, a pair of permanent magnets in the first direction takes over the function of the return position (first permanent magnets) and the other pair of permanent magnets, the function of Haptikerzeugung (second permanent magnets). During tilting into the other direction is reversed according to the function. That is, the tilt direction which defines first and second permanent magnets.

each of which a tilting direction perpendicular to the poling direction (the shortest connection line from the north to the south pole of the respective magnets) of the first permanent magnets and parallel to the polar direction of the second permanent magnets is preferred.

Preferably, a permanent magnet of the at least one pair of permanent magnets in a lateral arm of the operating lever is attached respectively. For the structurally simple securing or fixing the position one or more of the operating lever by gripping or locking pins formed thereon are also provided.

The invention further relates to the advantageous use of the operating element according to the invention in one of the advantageous embodiments described above, in a motor vehicle.

Further features and advantages of the invention result from the remaining claims and the following description of non-limiting embodiments of the invention, which are explained in more detail below with reference to the drawings. In these drawings schematically show:

Fig. 3B is a perspective view of the control element 1 shown in Fig. 1A, with the operating lever 7 is in the pivoted from the rest position position.

As can be seen from FIGS control element 1 of the invention comprises an operating lever 7 which has at its one free end facing the operator an operating button. 2 The operating lever 7 is pivotable by a bearing 3 in 4 directions in Figs. 1A, 1B, IC, and Fig. 3A rest position shown. As shown in FIGS. 1 and 1B, the operating lever is in the rest position on a flat surface on on a flat receiving surface of the hatched recorded portion of the bearing 3. The outer boundary of the support surface defines a rectangle the edges of which define so-called rocking edge 4 around which the operating lever can be tilted in four directions. 7 This tilting movement is a control and / or switching functionality associated with one or more sensors, not shown, and / or detectors via an unillustrated processing unit. The operating lever 7 has, at its other, remote from the operator end of two substantially orthogonal 7 pioneering and orthogonal to each other standing from the axis of the operating lever arm 5a, 5b. On these arms is in each case a permanent magnet, which in the rest position, respectively, an associated, but dormant permanent magnet 8, 9 spaced opposite, the opposite poles are respectively most closely. The pole direction of the two in each case forming a pair of permanent magnets 8, 9 are opposite. Depending on the tilting direction in accordance with this invention are the magnets which bring about the provision, called the first permanent magnets. 9 However, this association depends on the tilt direction. As can be seen from FIGS. 2A, 2B and 2C, the magnets provide 9, the pole direction is perpendicular to the tilt direction, at the same time for the return position, the displacement of the second permanent magnets 8 provides parallel to the poling direction to a tactile noticeable cogging torque whereby the "reset" is modulated and thus are seen haptically to the operator to leave the rest position. in a non-illustrated pivotal movement in a direction perpendicular to the paper plane direction, the magnets would exchange their function. the magnets 8 9 would take Haptikfunktion the second reset function of the first and the magnets . in the figures, 3A and 3B, the operating element of the invention is a perspective view, without represented the control knob. Even if the operating lever 7 by the magnetic forces of the magnets 8, is held in position 9, provide the formed on the operating lever 7 and received in recesses of the housing locking pins 6a 6b for a lag efixierung the operating lever 7, without impairing its pivoting.
