Description

The invention relates to an electrical switch according to the preamble of patent claim 1 or 3.

Electrical switches formed in the manner of a joystick and / or cursor switch and / or in the manner of a turntable serve to input data for an electrical appliance by a user. For example, such switches are used for car radios, navigation devices, on-board computers or search for controlling other functions in motor vehicles. In particular, such an electrical switch can also be used as a multi-function switch for menu control of functions via a display in the motor vehicle.

Such an electrical switch is from the US-A-4,459,440 known and has a movable in a pivot plane mounted actuator. The actuating member cooperates with a pivoting means such that the actuating member is pivotable in the pivoting plane in at least one direction from a neutral position in a pivot position assigned to this direction by the user. The pivoting position is formed as a switching position, such that the actuating member in the switching position acts on a switching element switching.

In the known switch, the actuator acts directly on the electrical switch designed as a switching element, whereby the switching position of this switch, especially with regard to a large-scale production, is very sensitive to tolerances. Furthermore, the known switch gives no indication of the realization of ergonomic requirements, in particular those which are desirable for use in motor vehicles. Finally, it is also not clear whether this switch is suitable for use in a motor vehicle with tight installation spaces.

Furthermore, such an electrical switch from the DE 296 04 717 U1 known. This switch has a movable actuator. The actuator cooperates with a rotating means such that the actuating member is rotatable by at least one angle from an initial position in at least one rotational position. The rotary position is formed as a display position, in which the actuating member acts on a switching element, sensor element, signal element o. The like. Actuating or switching.

In the DE 296 04 717 U1 No details are given to the formation of the rotating means. Above all, it is unclear how the angle between the initial and rotational position is determined. Furthermore, the known switch gives no indication of the realization of ergonomic requirements, in particular those which are desirable for use in motor vehicles. Finally, it is also not clear whether this switch is suitable for use in a motor vehicle with tight installation spaces.

The invention has for its object to further develop the switch so that the tolerance sensitivity between the actuator and the switching element is reduced. In particular, the actuator of the switch should be adjustable in several directions, with a secure sensing of several, for example 8 directions should be ensured with respect to a stable segment size of the individual segments for the Verschwenknchtungen.

Preferably, the switch should also be further developed such that the actuator is rotatable by a predetermined angle. In particular, a stop for the Drehfunkion clockwise and / or counterclockwise to be created. In particular, this stop should include a variable angle, which is specified by an external control signal.

This object is achieved in a generic electrical switch by the characterizing features of claim 1 or 3.

When switch according to the invention according to a first embodiment, the actuator cooperates with a lever such that the pivotal movement of the actuator is converted into a translated rotational movement of the lever. Next operated in the pivoting position of the lever, the switching element switching. Advantageously, even small Schwmkbewegungen be converted into sufficiently large actuation paths for the switching element, which reduces the sensitivity to tolerances.

In the switch according to the invention according to a second embodiment, the actuating member, in particular via the rotating means, coupled to an incremental ring. Further, a movable by means of an adjusting element latch is engageable with at least one window on the increment ring, so that the bolt constitutes a stop for the rotational function. The invention thus provides a central control element (ZBE) with adjustable stops, which are flexibly adaptable to the respective requirements in the motor vehicle in a simple manner.

Further embodiments of the invention are the subject of the dependent claims.

To extend the functionality of the switch, in each case the actuating member can additionally be designed to be rotatable and / or pivotable. For this purpose, on the one hand, the actuating member cooperates with a rotating means such that the actuating member is rotatable by at least one angle from an initial position into at least one rotational position formed as a switching position with a switching element. For this purpose, on the other hand, the actuating member cooperates with a pivoting means such that the actuating member is pivotable in a pivoting plane in at least one direction from a neutral position into a pivoting position. The pivot position is designed as a switching position, so that the switch generates a corresponding switching signal when the actuator is given. The functionality of the switch can finally be further increased when the actuator cooperates with a displacement means such that the actuator at least one distance from a Zero position in a displacement position is linearly movable. Preferably, the displacement position is formed as a switching element having a switching position, whereby the actuator allows a kind of "Enter" operation.

In a further embodiment, a switching flag can be arranged on the lever, wherein the switching flag in the pivot position, the switching element actuates switching. Furthermore, the switching element may consist of a sensor. In functionally reliable manner, in particular for use in motor vehicles, the sensor can then consist of an actuatable by the switching flag photocell.

For a particularly compact design, the pivoting means comprises a pivotally mounted at one end and arranged at the other end on the actuating rod joint rod. The lever may be rotatably arranged in a plane which is approximately perpendicular to the articulated rod in the neutral position. Furthermore, the lever can be configured as a one-armed lever, wherein the axis of rotation of the lever is located at one end thereof. The switching lug is arranged at the other end of the lever, in particular approximately perpendicularly projecting from the lever. Finally, in a compact embodiment, the hinge rod can pass through a recess which is located approximately centrally between the two ends of the lever, for rotation of the lever upon pivoting of the actuating member.

To realize a plurality of pivoting directions for the actuating member, the pivoting means comprises a universal joint for the pivotable mounting of the one end of the articulated rod. In a compact design, a further, second lever in approximately crosswise to the first lever, in particular substantially in the plane extending approximately perpendicular to the articulated rod in the neutral position, be arranged. In this case, the actuating member with the articulated rod actuates two, in particular geometrically differently configured, levers with switching lugs for the light barriers. For example, the first lever for the actuation of the photoelectric barrier during pivoting in north / south direction and the second lever for the actuation of the photoelectric sensors during pivoting in east / west direction serve. Without additional effort, the functionality of the switch can thereby increase that the operation of the photoelectric sensors when pivoting in Intermediate directions resulting from a combination of the rotational positions of the first lever and the second lever In such a configuration advantageously minimizes the translation of small Betatigungswege in large switching paths by means of lever arrangement scattering of the segment sizes by position deviations to the desired position of the sensors designed as light barriers.

Finally, the two motion translation levers of the actuator and the sensors configured as light barriers can be arranged in two mutually parallel planes which extend in the x-y direction. Such an arrangement results in a simple yet compact design. It makes sense that the plane for the sensors is formed by a printed circuit board.

It is advisable in a further embodiment, to arrange a further second, movable by means of an actuating element latch on the increment ring. With the help of the two bars each a stop for the rotary clockwise and counterclockwise rotation is created. As a result, the flexible adaptability of the switch is further increased. In a simple embodiment, it makes sense that the control element of a solenoid, an electric motor, a stepping motor, a piezoelectric element o. The like. There is.

In a compact embodiment, the rotating means comprises a rotatably mounted at one end and arranged at the other end on the actuator shaft. For a compact arrangement, it then makes sense that the shaft is arranged in the articulated rod. For storage, a rotary ring may be located at one end of the shaft. For the purpose of further compactness, the increment ring can be movable by means of a toothing of the rotating means, in particular of the rotary ring. Finally, for the purpose of good handling and particularly ergonomic operation by the user, it lends itself to the actuator comprising a rotary knob.

Especially in the function of a turntable, it is advantageous if, when the actuator is rotated by the switching element, successive pulses are generated when the rotary position is reached. In functionally reliable manner, the switching element a photocell. Teeth can be arranged on the increment ring, so that the pulses are generated by the light barrier by interaction of the teeth with the light barrier upon rotation of the increment ring.

To increase the ergonomics for the user, the incremental ring may cooperate with at least one spring-loaded ball for generating mechanical rotational locking positions. In addition, in such an embodiment, a locking at any position depending on the detent by a control signal allows. For example, 24 notches per revolution may be present, the locking takes place in each case in the locking position 12.

In order to avoid continuous energization of the solenoid, which saves energy, the solenoid can have two stable end positions. As a result, the bolt is movable by brief energization of the solenoid. For a compact arrangement in the ZBE, the latch is arranged on a lever. The lever may be configured like a fork, wherein the latch is located at one end of the lever and the other end of the lever is articulated to a plunger of the solenoid. Furthermore, the plunger is located on the side facing away from the increment of the lifting magnet, such that the fork-like lever engages around the lifting magnet.

For particularly preferred embodiments of the invention, the following can be seen.

Created is a central control element (ZBE) with a detection of 8 operating directions. A rotary knob with a shaft and a joint rod actuates two geometrically different levers with switching lugs for the sensors designed as light barriers. The first lever is for north / south operation. The second lever is for east / west operation. The intermediate directions result from the combination of the positions of the first lever and the second lever. The lever transmitter set and the sensors designed as light barriers are arranged in one plane, namely the xy plane. The translation of the small actuation paths in large switching paths minimizes scattering of the segment sizes due to position deviations from the nominal position of the sensors designed as light barriers.

The switch has a knob, wherein the rotational movement of the knob is guided via a shaft down and with a pair of gears from the axis of rotation and translated. The mechanical ball catch, for example, for 24 notches per revolution, forms a unit with the torque overload protection and increment ring with window for the bolt, which includes only a small tolerance chain. When signaling, the solenoid is actuated and the bolt engages in a window on the increment ring. The bolt locks the rotation of the increment ring in one direction, but allows a turning back by a certain angle. This leaves enough time to pull this latch by means of the solenoid as an actuator. This in turn allows further rotation. The signal detection takes place, for example, via switching lugs on the increment ring and a light barrier with 2 light curtains for detecting the direction of rotation. The actuator consisting of solenoids, the power levels for controlling the solenoids and the signal detection by the light barrier are arranged on a printed circuit board. By appropriate arrangement of two locking systems, it is possible to lock each actuation of a bolt system in a clockwise or counterclockwise direction. Upon actuation of both locking systems locking is achieved at any position depending on the detent, which consists for example of 24 detents per revolution.

The advantages achieved by the invention are in particular that a safe sensing of the pivoting, in particular of 8 directions, is possible with small Betätigungsigunpwegen for the actuator, for example of about 2.5 mm, with respect to a stable segment size of the individual segments in the mass production process ,

The advantages achieved by the invention are in particular that the example designed as a solenoid actuator does not require continuous power but has two stable end positions. The change of these end positions by brief Bestromungszeiten results in a low electrical consumption for the stop function in the ZBE, especially in comparison to the previously conventional motor brake.

Further advantages are that the switch manages in spite of high functionality with little space. Thus, the switch for tight spaces, as given in the dashboard, the center console, the armrest o. The like. In the vehicle are suitable. Furthermore, the switch is error-prone and has a long service life. The switch according to the invention can thus be used advantageously in harsh environmental conditions, for example in motor vehicles. In addition, the switch has a good feel, for example, the switch has eight preferential directions for the actuator at low actuation paths, which contributes to increasing the ergonomics. Despite high functionality of the switch is easy to operate, for example, with the fingers of one hand, with incorrect operations are largely excluded. In addition, the switch is inexpensive to manufacture.

In Fig. 1 is an inventive electrical switch 1 to see, which is designed in the manner of a joystick and / or cursor switch or multi-function switch. The switch 1 has an actuator 2, which is manually movable by the user in several different ways. First, the actuator 2 acts with pivoting means 3 together so that the actuator 2 is pivotable in a pivoting plane in at least one direction in the manner of a preferred direction by the user from a neutral position to a pivot position. Furthermore, the actuator 2 cooperates with Verachiebemitteln 5 such that the actuator 2 is linearly movable by at least a distance from a zero position in a displacement position by pressing the user in the manner of an "Eater" function. Finally, the actuator 2 still works with in Fig. 4 clearly visible rotating means 4 together so that the actuator 2 by the user by at least one angle from an initial position into a rotational position is rotatable. The pivot position, the Verschiobeatellung and the rotational position are each formed as a switching position, such that the actuator 2 in the respective switching position on an associated switching element 6, 24, 35 (see this search Fig. 4 ), Sensor element, signal element o. The like. Acting switching. The switching element 35 for the displacement position consists of a switching mat, which offers a certain feel to the user when pressing the actuator 2.

The switch 1 has a housing 7, which in turn consists of an upper housing part 7 'and a lower housing part 7 "protrudes from the housing 7, namely on the upper housing part 7', the Eatigungseorgan 2 for operation by the user Actuator 2 comprises a knob 9, wherein the knob 9 at one end of a link rod 8 and a shaft 20 (see Fig. 4 The pivoting means 3, the Verschicbemittel 5 and / or the rotating means 4 are based on the mounted in the housing 7 articulated rod 8 with the shaft 20. In this case, the pivoting means 3, as can be seen from Fig. 2 When pivoting now the actuator 2 acts by means of the hinge rod 8 with the lever 10 such that the pivotal movement of the actuator 2 is converted into a translated rotational movement of the lever 10, the lever 10 is a further Switch lug 12 is arranged so that the switching lug 12 actuates the switching element 6 in the pivoting position switching. In the present case, the switching element 6 consists of a sensor, namely an actuatable by the switching flag 12, fork-like light barrier 6, which is located on a housing 7 located in the x- / y-direction extending parallel to the plane 14 circuit board 17.

How to continue in Fig. 2 sees, the lever 10 is rotatably mounted in the plane 14 which is approximately perpendicular to the articulated rod 8 in the neutral position. The lever 10 is designed as a one-armed lever, wherein the axis of rotation 15 of the lever 10 is located at one end thereof. The switching lug 12 is at the other end of the lever 10, in approximately perpendicularly projecting from the lever 10, respectively. The pivot rod 8 passes through a recess 16 which is located approximately centrally between the two ends of the lever 10, for rotation of the lever 10 upon pivoting of the rotary knob. 9

In the present case, the actuator 2 is not only in one direction but in the manner of a wind rose according to the Fig. 3 in multiple directions, in eight, with the cardinal directions directions, pivotally configured by the hinge rod 8 is mounted in a universal joint 18 in the housing 7 and with a direction defining, and the pivoting feel for the user generating pivoting gate 19 cooperates, which in Fig. 1 you can see. For detecting these pivoting directions, further light barriers 6 'are arranged on the printed circuit board 17. On the other hand, another, second lever 11 is arranged with a switching lug 13 in approximately crosswise to the first lever 10 substantially in the plane 14, such that the knob 9 during pivoting by means of the pivot rod 8 with the shaft 20 disposed therein these two geometrically differently ausgestalteteten Lever 10,11 with switching lugs 12, 13 for the photoelectric sensors 6,6 'actuated. The first lever 10 serves for the actuation of the light barriers 6 when pivoting in north / south direction and the second lever 11 for the actuation of the light barriers 6 'when pivoting in east / west direction. The actuation of the light barriers 6, 6 'when pivoting in intermediate directions resulting from a combination of the rotational positions of the first lever 10 and the second lever eleventh

By means of the four light barriers 6, 6 ', eight pivoting directions of the actuating member 2 can thus be detected by evaluating the signaling of the respective light barriers 6, 6'. How to get by Fig. 3 sees, the signaling of the photoelectric sensors 6, 6 'takes place in the eight directions with approximately the same segment size. The translation of the small actuation paths the knob 9 during pivoting means the lever 10, 11 in large switching paths for the switching lugs 12, 13 minimizes scattering of the segment sizes by position deviations to the desired position of the photoelectric sensors used as sensors 6, 6 '. How to continue in Fig. 2 sees, the two levers 10,11 serving for movement translation of the rotary knob 9 and the light barriers 6, 6 'in two mutually parallel planes 14,17 are arranged.

As already mentioned, the Betätigungsorsan 2 is designed to be rotatable. How to get in Fig. 4 sees the rotation means 4 for the knob 9, the shaft 20 and a rotary ring 21. The actuator 2 is further coupled via the rotating means 4 with an increment ring 22 by the increment ring 22 is movable by means of acting as a gear toothing 23 of the rotating means 4 , The switching element 24 for detecting the rotation of the rotary knob 9 consists of a fork-shaped light barrier. On the increment ring 22 teeth 25 are arranged, which are movable through the bifurcated light barrier 24 therethrough, so that pulses are generated by the photocell 24 upon rotation of the increment ring 22. To generate rotational locking positions and for the feel of the rotational movement of the increment ring 22 cooperates with at least one not shown, spring-loaded ball, which in corresponding, in Fig. 5 visible holes 26 engages the Incrementring 22.

The rotational function of the actuator 2 has an adjustable stop, so that the number of Drehincremente can be limited in a variable manner. For this purpose, a movable by means of an adjusting element 27 bolt 28 in engagement with at least one, bavoraugterweise a plurality of windows 29 on the increment ring 22 can be brought, so that the bolt 28 represents the stop for the rotational function. The adjusting element 27 may be a lifting magnet, an electric motor, a stepping motor, a piezoelectric element or the like.

How to use the Fig. 5 detects, the latch 28 is disposed on a lever 30, wherein the lever 30 is configured like a fork. The latch 28 is located at one end of the lever 30 while the other end of the lever 30 is on a plunger 31 of the solenoid 27 is on. The plunger 31 is located on the side facing away from the Inkrementring 22 of the solenoid 27, such that the fork-like lever 30, the solenoid 27 in order compact arrangement in the housing 7 surrounds. The solenoid 27 has two stable end positions, whereby the solenoid 27 does not require continuous power, but rather the latch 28 is movable by only brief energization of the solenoid 27.

In such a manner, in each case a stop for the rotary function of the rotary knob 9 is realized in a clockwise and counterclockwise direction. For this purpose, a second second, by means of a solenoid 27 'movable latch 28' on the increment ring 22 is arranged, as can be seen from the Fig. 4 sees. The two bars 28, 28 'each provide a variable stop for the rotational function of the knob 9 in a clockwise and counterclockwise direction. Namely, the solenoid 27 is used for blocking the clockwise rotation and the solenoid 27 'for blocking the counterclockwise rotation. Finally, the increment ring 22 can still be a slip clutch 32 according to Fig. 5 to ensure torque overload protection when the respective stops act. Furthermore, in Fig. 5 nor an electronics located on the circuit board 17 33 for controlling the solenoids 27, 27 'and a cable outlet 34 for contacting the switch 1 with, for example, a bus system to see.

Such a multi-function switch can be used for car radios, for navigation systems and / or for control devices, displays o. The like. In motor vehicles. However, the invention is not limited to the described and illustrated embodiment. Rather, it also encompasses all expert developments within the scope of the invention defined by the claims. In addition to Kraftfehrzeuganwendungen such a multi-function switch can be used advantageously as input means for computers, machine tools, household appliances o. The like. Finally, the invention can be used not only in the described multi-function switches but also in such switches, in which the actuator only pivoted or is designed only rotatable in the manner of a turntable.
