Definitions
- the present invention relates to an operating element, in particular a joystick, with a tilting feel for a motor vehicle.
- control elements are often used, which are operated by tilting. Examples include toggle switches for power windows or electrically adjustable exterior mirrors and joysticks for controlling an on-board computer.
- a force variable over the deflection is necessary for the operation of the operating element.
- a typical force curve is indicated in FIG.
- this force is typically generated by one or more springs, which optionally additionally return the control to a center position when the user releases.
- the disadvantage of using springs is that the spring force decreases over the lifetime of the control element and an optimal force curve over the deflection of the control element can not be achieved. Also, the achievable by springs forces are limited. In addition, the quality of the generated feel is often unsatisfactory.
- An inventive control element has a tiltably mounted lever with a first and a second end of the lever, wherein the first end of the lever extends out of a housing of the operating element.
- the user moves the protruding from the housing first lever end and thus generates a tilting movement of the lever about its bearing point.
- the operating element has a pivotally mounted lever arm with a receiving element and a power transmission element at the second end of the tiltably mounted lever, wherein the force transmission element extends into the receiving element of the lever arm and transforms a tilting movement of the lever into a pivoting movement of the lever arm.
- a permanent magnet pair is arranged in the control element, wherein a magnet of the permanent magnet pair on the lever arm and a magnet is fixedly arranged in the operating element such that in the center position of the lever each unequal poles of the magnets are spaced.
- the attraction between the two magnets of the permanent magnet pair generates a force on the lever arm, which forces it into a zero position, which simultaneously causes a middle position of the lever.
- the deflection of the lever arm from this zero position takes place in that the user tilts the lever, whereby the arranged at the second end of the lever power transmission element moves in the receiving element of the lever arm.
- the force transmission element presses against an edge of the receiving element, whereby a force is exerted on the lever arm, which swings it out of the neutral position.
- this pivotal movement is the attraction of the permanent magnets, which transmits to the lever via the force transmission element and is perceived by the user as a haptic impression.
- the lever arm is always swung out in the same direction from its zero position. This also applies if the lever is moved translationally along its longitudinal axis to produce a so-called push functionality.
- the force exerted by the permanent magnet pair on the lever arm is dependent on the relative position of the two permanent magnets to one another and thus of the deflection of the lever arm.
- the deflection of the lever arm is dependent inter alia on the deflection of the lever and the shape of the receiving element on the lever arm and the power transmission element. If the flanks of the receiving element on the lever arm are flat, a deflection of the lever leads to a smaller deflection of the lever arm than with a steep flank of the receiving element.
- the shape of the receiving element in the lever arm can be freely designed, so that an individual feel with the desired force curve can be realized for each tilting direction of the lever.
- the receiving element is preferably formed by a recess in the lever arm. Such a recess can be produced precisely and inexpensively in the production of the lever arm. Alternatively, the receiving element of any other, suitable Formed the lever arm. In a further alternative, the receiving element is an independent component which can be fastened on the lever arm, for example latched. By such a modular design, the feel of the control element can be adapted in a simple manner with otherwise the same structure.
- the force transmission element is preferably a ball. Upon actuation of the control element, the ball rolls in the receiving element on the lever arm, resulting in low friction and low wear.
- the force transmission element is a shaping of the second lever end. The end of the lever slides directly over the flanks of the receiving element.
- the force transmission element is designed as a pyramid.
- the base of the pyramid has as many edges as the lever possible tilting directions.
- the base of the pyramid for example, in four tilt directions of the lever as a square and formed in eight tilt directions of the lever as an equilateral octagon.
- An embodiment of the power transmission element as a cone allows infinitely many tilting directions of the lever.
- the power transmission element is designed as a pin whose first end is arranged on a plate and whose second end forms a tip. The shape of the plate is analogous to the base of the pyramid adapted to the possible tilting directions of the lever.
- the operating element has a mechanical end stop for the lever and / or the lever arm.
- An end stop for the lever arm makes it possible to reach an end stop for all tilting directions of the lever with just one component. Through a mechanical end stop for the lever a depending on the tilting direction of the lever end stop can be realized.
- a shift gate for limiting the possible tilting directions of the lever is arranged in the operating element according to the invention.
- only desired tilting directions of the lever are permitted, for example four or eight.
- the maximum deflection of the lever can be individually limited by the shift gate for each tilt direction.
- tilting directions permitted by the shifting gate are dynamically lockable. Thereby, the number of tilting directions depending on the state of the operated device during operation can be further limited.
- the shape of the receiving element on the lever arm limits the possible tilting directions of the lever.
- the receiving element for example, star-shaped grooves, in which the force transmission element moves when tilting the lever. A movement of the force transmission element outside of the grooves is not possible, thereby blocking corresponding tilting directions of the lever.
- the operating element preferably has at least one reflection light barrier for detecting the tilting direction of the lever.
- Transmitter and receiver of the reflection light barrier are arranged, for example, stationary in the operating element, while the reflector, for example in the form of a reflective surface, is arranged directly or indirectly on the lever.
- the distance of the reflecting surface to the transmitter and receiver changes, which leads to a change in the output signal of the reflection light barrier.
- the tilt direction of the lever is determined from the output signal of the reflection light barrier.
- the operating element has at least one forked light barrier for each possible tilting direction of the lever, each forked light barrier detecting a possible tilting direction of the lever.
- the operating element has at least one sliding contact for detecting the tilting direction of the lever.
- the sanding spring makes contact with another contact surface or another position within a contact surface. From this, the position of the lever can be determined.
- the operating element has a light barrier, in particular a fork light barrier, for detecting the pivoting movement of the lever arm. If the lever has been tilted or pushed over a switching threshold, then a predetermined deflection of the lever arm is reached or exceeded. This reaching or exceeding is detected by means of the forked light barrier.
- the switching threshold refers to the deflection of the lever, in which the operating element is considered to be actuated. It is exemplified in FIG.
- the advantage of using a light barrier lies in the reliable detection of the switching threshold. If this switching threshold is reached, the tilting direction of the lever or a pushing of the lever is detected by means of the elements listed above.
- a zero force switch is used for detection used the pivoting movement of the lever arm.
- a zero-force switch is a switch which does not counteract its actuation with little or no force, and thus does not appreciably affect the feel produced by means of the Permamer.trnagnetpoves.
- a control knob is arranged at the first end of the lever.
- This control knob allows a safe and comfortable operation of the control element.
- the control knob on more features, such as a turntable.
- the control knob is mounted elastically on the first end of the lever, for example by means of a spring. This allows a targeted adjustment of the push-feel.
- An inventive control panel thus has the advantage of being able to produce a precisely determinable feel for each tilting direction, wherein the haptic profile can be the same in particular for each tilting direction. Also, the realization of a push haptic is possible. Due to the configuration of the receiving element on the lever arm, the tilting directions of the lever can be limited without further components. In addition, the lever is centered by the interaction of the force transmission element with the receiving element on the lever arm reliably in the center position.
- tilt direction evaluation device for an operating element with a tiltable handle, in particular an operating element as described above.
- This tilt-direction evaluation device has at least one light barrier, a mask fixedly arranged in the operating element with at least one recess and a shielding element connected to the handle and movable relative to the mask, the shielding element not having one, one or more recesses of the mask depending on the position of the handle covered.
- the mask serves to limit the beam path of a light barrier to a defined spatial area.
- recesses are introduced into the mask, in particular in the form of slots.
- the shielding element is arranged in the operating element such that it moves relative to the mask when the handle is actuated.
- the shielding element is impermeable to the light of the light barriers, wherein optionally transparent areas are introduced into the shielding element. These areas are formed for example by a recess or a window of translucent material.
- the shielding element conceals a recess of the mask if and only if an opaque rich above the recess.
- the handle is, for example, the lever of the control element described above.
- the opaque areas of the shielding cover with unconfirmed handle none of the recesses in the mask.
- an opaque region of the shielding element slides over one or more recesses of the mask and thus interrupts the associated light barriers. Based on these interruptions, the tilting direction of the handle can be determined.
- the tilt-direction evaluation device has at least one light barrier for each possible tilting direction of the handle. This ensures that the switching threshold can be accurately positioned for each tilting direction by the shielding interrupts the associated light barrier at a predetermined deflection of the handle in this tilting direction.
- the switching threshold is preferably for all tilt directions at the same deflection of the handle.
- eight possible tilting directions can be detected by means of four light barriers, which are preferably arranged evenly spaced on a circular path. In an oblique deflection of the handle so two light barriers are interrupted by the shielding.
- two light barriers have a common light source.
- the common light source is arranged so that the light emitted by it hits two photosensors through two recesses in the mask.
- Each beam path from the light source to one of the photosensors can be interrupted by the shielding element independently of the other beam path. This leads advantageously to a reduced number of light sources with a constant number of light barriers.
- a light source can also be shared by three or more light barriers.
- the shielding element is formed star-shaped.
- Each arm of the star serves to cover one or more recesses of the mask.
- the shielding element consists of a single arm, which is designed so that it can cover any recess of the mask.
- the shielding element is ring-shaped or disc-shaped.
- the shielding element consists of a flexible material, in particular a film.
- a flexible material is that the shielding element can deform on contact with the mask and can therefore ringem distance from the mask can be attached to the handle.
- a rigid shielding element has to be arranged so far from the mask on the handle that the shielding element does not or only slightly touches the mask when the handle is actuated. The deformability of a flexible shielding element therefore leads to increased freedom in the design of the operating element and a reduced overall height.
- a masking element resting against the mask reliably covers the recesses in the mask.
- the flexible shielding element has a plate-shaped cross section. Because of this plate-shaped cross section, the ends of the shielding element are preferably already in the center position of the handle with slight pressure on the mask.

- Figure 1 shows a sectional view of an operating element 1 according to the invention with a tiltably mounted in a housing 5 lever 2.
- a first end 3 of the lever 2 extends out of the housing 5.
- the second end 4 of the lever 2 has a recess which receives parts of a ball 8. Another part of the ball 8 is received by a receiving element in the form of a recess 7 of a pivotally mounted lever arm 6.
- the control element 1 further comprises a pair of permanent magnets 9, wherein a magnet 10 on the lever arm 6 and a magnet 11 is fixedly arranged in the housing 5.
- the magnets 10 and 11 are arranged in such a way that unequal poles face each other at a distance.
- the north poles of the magnets are hatched and the south poles of the magnets shown dotted.
- FIG. 2 a shows a further partial section of the operating element 1 with a few further components.
- the second lever end 4 and thus the ball 8 moves to the left.
- the ball 8 presses against the edge 12 of the recess 7 and thus pivots the left end of the lever arm 6 against the attraction of the permanent magnet pair 9 down.
- the left end of the lever arm 6 also pivots downward when the first end 3 of the lever 2 is tilted into the plane of the drawing or out of the plane of the drawing. Therefore, the left end of the lever arm 6 pivots at each actuation of the operating element 1, regardless of the tilting direction of the lever 2 down.
- the ball 8 serves as a force transmission element, which converts the tilting or pushing movement of the lever 2 into a pivoting movement of the lever arm 6.
- FIGS. 2 a to 2 d furthermore show a reflection light barrier 14 with a transmitter 15 and a receiver 16.

- a projection 19 arranged on the lever arm 6 is inserted.
- the projection 19 interrupts the fork light barrier 18.
- the switching threshold and the lever arm 6 thus achieved a certain deflection, as in 2b and 2c is shown, or the lever 2 was pressed as shown in Figure 2d along its longitudinal axis to above the switching threshold, the projection 19 is no longer in the detection range of Gabeiiicht battlee 18. This causes a change in the output signal of the forked light barrier 18, by means of which the operation of the operating element 1 is detected. If this operation has been detected, it is determined whether and in which direction the lever 2 has been tilted or whether the lever 2 has been pressed.
- FIG. 3 shows parts of an alternative embodiment of an operating element 21, in which the second end 24 of the lever 22 is designed as a force transmission element 28.
- the rounded end 28 of the lever 22 slides over the flanks of the introduced into the lever arm 26 recess 27 and pushes the free end of the lever arm 26 down.
- the advantage of this embodiment is the simple structure, in which no further element, for example in the form of a sphere, is necessary.
- FIGS. 20a to 20f Various possible embodiments of the receiving element are indicated in FIGS. 20a to 20f. It is assumed that these are recesses in the lever arm. However, the receiving element may for example also be formed by a different shape with the specified shape.

From this interruption of the left light barrier detects an unillustrated electronics that the lever 122 has been tilted to the right.
- FIG. 11 shows a top view of the mask 123 and the shielding element 124 from FIGS. 9 and 10 in the middle position of the lever 122.
- the shielding element 124 Upon actuation of the lever 122, the shielding element 124 is displaced relative to the mask 123 and conceals one or more of the recesses 135, whereby the associated photocells are interrupted. From the information about the interrupted light barriers, the tilting direction of the lever 122 can be determined.
- FIGS. 12 and 13 show the operating element 141 as a modification of the operating element 121 from FIGS. 9 and 10.
- the operating element 141 has a mask 143 with recesses 149.
- a flexible, cross-shaped shielding member 144 is arranged with four arms, which has a plate-shaped cross section in the sectional view in Figure 12. Flexible means that the shielding element is deformable by the movement of the lever 142.
- the lever 142 is shown in its central position.
- the ends of the arms of the shielding member 144 rest on the mask 143 and do not obscure the recesses 149.
- the light of the light-emitting diodes 145 and 147 thus impinges on the photodiodes 146 and 148, respectively.
- the plan view of the mask 143 and the shielding element 144 corresponds analogously to the plan view from FIG. 11.
- FIG. 14a shows the top views of possible embodiments of the shielding in four possible tilting directions of the lever.
- the shielding element 161a is cross-shaped, with light-permeable windows 162a being introduced into the ends of the four arms. In the middle position of the lever all windows 162a are above the recesses 163a, so that none of the light barriers is interrupted.
- the shielding element 161a covers the left-hand recess 163a in the mask 160a, but the right-hand recess 163a is still in the region of the right-hand window 162a in the shielding element 161a and the right-hand light barrier will not interrupted.
- the functioning of the shielding elements 161b in FIGS. 14b and 161d in FIG. 14d is analogous to that of the shielding element 161a in FIG. 14a.
- the shielding element 161b consists of an annular basic structure which has cross-shaped extensions. In these extensions window 162b are introduced.
- the shielding member 161d is disc-shaped, wherein the window 162d are inserted into the disk.
- the shielding element 161c in FIG. 14c is also disk-shaped, but the pane has no windows. Upon a tilting movement of the lever, the disc 161c is displaced with respect to the mask 161c so as to obscure one or more of the recesses 163c.
- the shielding elements 161e, 161f and 161h in FIGS. 14e, 14f and 14h are constructed analogously to those in FIGS. 14a, 14b and 14d, but each have eight windows in order to be able to detect eight tilting directions of the lever.
- the shielding member 161g of Figure 14g is again disc-shaped and not provided with windows. Upon a tilting movement of the lever, the disc 161g is displaced with respect to the mask 161g so as to obscure one or more of the recesses 163g
- FIGS. 15a to 15e show the individual components of a tilt direction evaluation device.
- FIG. 15a shows a printed circuit board 170, on the upper side of which in each case four photosensors 171, 172, 173 and 174 are arranged in pairs. The photosensors 171 and 172 detect an operation of the operating member to the left or right, the photosensors 173 and 174, an operation up or down.
- FIG. 15b shows a printed circuit board 177, on the underside of which light-emitting diodes 175 and 176 are arranged.
- the printed circuit boards 170 and 177 are arranged in a control element such that the light-emitting diode 175 illuminates the photosensors 171 and 172 and the light-emitting diode 176 illuminates the photosensors 173 and 174.
- the mask 178 from FIG. 15c and the shielding element 183 from FIG. 15d are arranged between the printed circuit boards.
- slot-shaped recesses 179, 180, 181 and 182 are introduced.
- the shielding element 183 consists of two arms arranged at right angles to one another. In the first arm, the windows 184 and 185 are introduced, in the second arm, the windows 186 and 187.
- the windows 184 to 187 in contrast to the rest of the shielding element 183 permeable to the light of the light emitting diodes 175 and 176.
- FIG. 15e shows a three-dimensional view showing the spatial configuration of the shielding element 183. The windowed ends of the arms of the shielding member rest on the mask 178.
- the photosensors 171 and 172 or 173 and 174 are optionally arranged offset against one another like a checkerboard. This simplifies the mountability on the circuit board 170 and reduces the stray light that passes through a different than the recess of the mask 178 associated with the photosensor.
- Figure 15f shows a plan view of the assembled components of Figures 15a to 15d, wherein the circuit board 177 has been omitted.
- the LED 175 radiates its light through the recess 179 on the photosensor 171 and through the recess 180 on the photosensor 172.
- the LED 176 emits its light through the recess 181 on the photosensor 173 and through the recess 182 on the photosensor 174.
- FIG. 16 shows a control element with the tilt direction evaluation device from FIG. 15f.
- the areas illuminated by the light emitting diodes 175 and 176 are shown.
- Figure 21 shows a section through a part of a control element according to the invention.
- a spring 233 is pushed, which rests on a projection 234 of the lever 230.
- a control knob 232 is further pushed, which has a projection 235 which cooperates with the spring 233. If the push functionality of the operating element is used, that is pressed down the control knob 232, both the spring 233 is compressed and the lever arm, not shown in Figure 21 - as described in the above examples - pivoted against the attraction of the permanent magnet pair, also not shown. The actuation of the control knob 232 is thus counteracted by a counterforce consisting of the clamping of the spring force and the magnetic force transmitted via the lever arm.
- This push-feel is therefore adjustable independently of the tilt feel by means of the spring 233.
- the pushing of the control knob 232 and the lever 230 is detectable by means of a light barrier, not shown, or a switch.
- a light barrier not shown, or a switch.
- the above exemplary embodiments are to be understood as purely exemplary. In particular, the shape and the arrangement of the individual elements may deviate from the described embodiments, without departing from the inventive idea.
- This relates in particular to the bearing of the lever, the shape of the receiving element on the lever arm and the configuration of the force transmission element. In principle, the shape of the flanks of the receiving element on the lever arm for each tilting direction of the lever can be configured individually, whereby a kippidesspare haptics can be generated.
- the push function and the operation of the operating element other elements than the aforementioned light barriers or sliding contacts can be used.
- the operating element can also be designed, for example, as a seesaw or a cross-rocker.
