Description

The invention relates to an operating device for a motor vehicle, in particular for operating a sunroof of the motor vehicle, with a carrier element and an operable by an operator and pivotally mounted on the support member about a pivot axis control element, which from a starting position in a first tilting direction and in the first Tilting direction opposite second tilting direction can be tilted in each case in at least one tilted position about the pivot axis. The invention also relates to a motor vehicle with a movable component, in particular a sliding roof, and with such an operating device for controlling the movable component.

In the present case, the interest is directed in particular to an operating device or a switch, which is designed to operate a sunroof in a motor vehicle. Such operating devices are already known from the prior art in a variety of configurations.

An operating device with a control element designed as a toggle switch is, for example, from the document DE 692 09 370 T2 known. The operating element is pivotally mounted on a housing, in which at least one connection circuit is arranged, wherein an actuating element interacts with the operating element such that at least two arc contacts can be actuated in succession. The two sheet contacts are arranged side by side and substantially in the same horizontal plane.

The known from the prior art operating devices for operating sliding roofs have the disadvantage that they are typically designed relatively complex and the operation of the sunroof is therefore correspondingly confusing. In sliding roofs, which are both tiltable and movable, usually different controls are used, which are provided for these different types of movement of the sunroof. This is very confusing.

Another disadvantage of the known operating devices for operating sliding roofs or other movable vehicle parts is that the haptic feedback in the respective positions of the operating element is usually generated by means of a switching mat, which is often also formed integrally with electronic microswitches. It has now been found that such safety mats for the generation of the necessary operating haptics only insufficient or the forces generated by the switching mat are insufficient. On the other hand, such a switching mat - which is usually formed of an elastic material - is a wearing part, which in turn causes the haptic forces over time can also decrease.

It is an object of the invention to provide an improved over the prior art operating device for operating a movable component of a motor vehicle, in particular for controlling a sunroof, and to provide a motor vehicle with such an operating device.

This object is achieved by an operating device and by a motor vehicle with the features according to the respective independent claims. Advantageous embodiments of the invention are the subject of the dependent claims, the description and the figures.

An operating device according to the invention for a motor vehicle is designed in particular for operating a movable component of a motor vehicle, preferably for operating a sunroof. The operating device has a carrier element and an operating element. The operating element is mounted pivotably about a pivot axis on the support element and can be actuated by a user. The user can tilt the operating element from a starting position into a first tilting direction and into an opposite second tilting direction respectively into at least one electrically or electronically detectable tilting position about the pivot axis. For example, the operating device comprises an electronic switching device which can be actuated in the tilted positions of the operating element. For example, this switching device comprises for each tilted position in each case at least one electrical contact element or a microswitch, which / which is actuated in the associated tilted position of the operating element, wherein this operation can be detected by means of an electronic evaluation device or circuit arrangement. The operating device further comprises a base part on which the carrier element with the operating element from the initial position in a sliding direction in at least one operating position displaceable, in particular displaceable in a straight line, is mounted. The operating device also has a haptic device for generating a haptic feedback in the at least one tilted position and / or in the at least one actuation position. This Haptikeinrichtung has a spring-loaded control cam and an associated control track, along which the control cam between detent positions for generating the haptic feedback upon actuation of the control element is displaceable.

According to the invention therefore an operating device is provided with a control element, which is designed both as a toggle switch and as a slide switch. Such an operating device allows a clear operation of moving components, in particular sliding roofs, which have different types of movement. In particular, the use of the operating device according to the invention proves to be particularly advantageous in a sunroof. By tilting the operating element namely a tilting movement of the sunroof can be controlled, while by sliding the operating element (with the associated support member) a sliding movement of the sunroof can be performed. This allows a total of a particularly intuitive and clear operation of a sunroof. In this case, the operating device can be constructed in a relatively simple manner, and it is only a pivot bearing and a sliding bearing required. The robustness of the operating device is also improved by the special Haptikeinrichtung, which in particular manages without a switching mat and instead has a spring-loaded control cam or a spring plunger and an associated control track or detent path against which the control cam is supported under load with a spring force and along which the control cam is moved upon actuation of the operating element to generate a haptic pulse and thus a haptic feedback to the user in predetermined locking positions which correspond to the at least one tilt position and / or the at least one actuation position and / or the starting position itself. By means of such a control cam and such a control track, a reliable haptic feedback can be generated. The control track can be designed, for example, as a sliding surface for the control cam or alternatively as a guide for the cam.

The base part preferably represents a housing on which the carrier element is slidably mounted with the operating element in the sliding direction. Thus, the control element is pivotally mounted on the carrier element, which in turn is displaceably mounted on the base part. Thus, the control element is indirectly mounted on the carrier element on the base part slidably, so that a mechanical decoupling of the sliding function on the one hand and the tilting function is realized on the other hand, which additionally increases the robustness of the operating device. In addition, this allows that when tilting the sliding function and / or when moving the tilt function can be blocked without much effort.

Preferably, the operating element is asymmetrical in such a way that on the one hand it has a convex shape and has a bulbous vault and on the other hand has a recess pointing in the direction of the interior of the operating element. In this way, the tilting of the operating element takes place in the first tilting direction by pulling the operating element with at least one finger on the indentation, while the tilting of the operating element takes place in the second tilting direction by pressing the operating element on the bulbous vault. Such embodiments are already known to be known from the prior art and are commonly used in electronically movable windows of motor vehicles. The finding is that such a design also proves to be particularly advantageous in combination with a sunroof.

Preferably, the haptic device comprises a first control cam and an associated first control track for generating the haptic feedback in the at least one actuation position (when moving) and a second control cam and an associated second control path for generating the haptic feedback in the tilted positions (when tilting). Thus, separate control cam for shifting and tilting are used, which are each acted upon by a spring force. Both when tilting and when moving the control element, the operating haptic can thus be generated particularly reliable and effective.

It proves to be advantageous if the first control cam is arranged on the carrier element and the first control track is formed on the base part. When moving the carrier element (with the operating element) relative to the base part thus slides the first control cam under load with spring force on the associated first control track, so that upon displacement of the support member relative to the base member haptic feedback is generated in the operating positions. The storage of the first control cam on the support element also has the advantage that the already required minimum width of the support element or the required minimum width of the control element is utilized and thus the provision of an additional space for the control cam is unnecessary. As a control path here an already existing surface of the base part can be used.

Accordingly, the second control cam can be arranged on the operating element itself, while the second control track can be formed on the carrier element. If the operating element is pivoted relative to the carrier element, the second control cam thus slides under load with spring force on the second control path, so that when the operating element is tilted, a haptic feedback is generated in the tilted positions. Here too the required minimum width of the control element for the storage of the second control cam is utilized. As a control path, the already existing, the operating element facing surface of the support element can be used.

Preferably, the sliding direction of the operating element is perpendicular to the pivot axis. The sliding direction preferably also runs parallel to a bottom or a bottom side of the operating element or of the base part and thus in particular also parallel to a user interface on which the operating device can be arranged. Thus, the displacement of the operating element is particularly intuitive, because the displacement of the operating element can be made substantially in the same direction as the tilting.

Preferably, the control element from the initial position in a direction opposite to the first sliding direction second sliding direction in at least one operating position can be displaced. Thus, the functionality of the operating device is further expanded because the control element can be moved from the starting position into two opposite sliding directions along a common sliding axis in each case in at least one operating position. For example, in a sliding roof this can be opened by moving the control element in the first sliding direction and closed by moving the control element in the opposite second sliding direction again.

Preferably, the operating device has an electronic switching device which is actuated in the tilted positions of the operating element by means of a decoupling disk of the operating device. This decoupling disc may be pivotally mounted on the base part, wherein on the operating element, a driver element may be formed, which pivots when tilting the operating element relative to the carrier element, the decoupling disc in an active position in which the decoupling disc actuates the electrical switching device. Since the switching device is not actuated directly by the operating element when the operating element is tilted, but indirectly by the decoupling disk, the switching device can be arranged locally separately or spatially independently of the operating element.

The connection between the operating element and the decoupling disk is preferably designed so that the decoupling disk is moved into its active position only when tilting the operating element, but not when moving the operating element. For this purpose, the decoupling disc may have a longitudinal recess formed along the sliding direction, in which the driver element of the operating element is slidably received. If the operating element is displaced along the sliding direction, then the driver element moves along the elongate recess and thus does not actuate the decoupling disk. If, however, the operating element is pivoted, the entrainment element moves the decoupling disk into the active position, in which the decoupling disk actuates the electrical switching device. Here, the decoupling disk can actuate, for example, a microswitch of the switching device.

For the sliding movement, a further, separate switching device is preferably provided, which may also have at least one micro-switch. This is operated when moving the operating element.

Preferably, the control element can be tilted from the initial position in the first and in the second tilting direction in each case in two different tilted positions about the pivot axis, in each of which at least one switching element of the switching device is actuated. Thus, two tilt positions are provided in each tilting direction, which can be detected by means of the electrical switching device. In each tilted position, the haptic device preferably generates a haptic feedback or a slight force pulse to the operating element, so that the user can perceive the reaching of the tilted positions haptically. The provision of two tilt positions in each tilt direction of the operating element has the advantage that a multiplicity of functions can be implemented with the operating element. In particular, it may be provided that by tilting the operating element in a first tilted position, the sunroof or another movable component is moved (in particular opened) as long as this first tilted position is maintained or the user holds the operating element in this first tilted position. By tilting the control element further in the same tilting direction into a second tilted position, the sunroof can be fully opened to the stop, regardless of whether the user keeps holding the operating element or not. By tilting the control element in the further second tilted position, the sunroof can thus be fully opened even when the user releases the control immediately.

The operating device is preferably designed so that the control element is automatically brought from the tilted positions and from the operating positions in the starting position, namely in particular by means of a spring force. After releasing the control by the User returns the control thus automatically or automatically in the starting position.

Preferably, also with respect to the sliding movement of the operating element is provided that from the initial position, the operating element in the sliding direction, and in particular in the opposite second sliding direction, (respectively) in two different operating positions is displaced, which can be detected or detected by means of an associated switching device , Also in these operating positions, a haptic force or feedback is generated on the control element and thus on the user, which is provided by the associated control cam and the associated control track.

Preferably, blocking means are provided which mechanically prevent or block the displacement of the operating element in the sliding direction in at least one of the tilted positions, in particular in each tilted position. This prevents the sliding function from being executed simultaneously when the tilt function is executed. If the operating element is tilted, the blocking means prevent an additional displacement of the operating element in the sliding direction. Such blocking agents prove to be particularly advantageous in a sunroof, which is both tiltable and slidably mounted. When tilting the sunroof namely the generation of additional control signals is prevented, which otherwise provide for the displacement of the sunroof. Operating errors and destruction of mechanical parts can thus be avoided.

Preferably, blocking means are additionally or alternatively provided which mechanically block the tilting of the operating element about the pivot axis in a position of the operating element which is shifted in the sliding direction in relation to the starting position. Thus, the tilting of the control element is only possible if the control element is in its initial position and thus is not moved in the sliding direction.

In one embodiment it is provided that the blocking means for blocking the displacement and the blocking means for blocking the tilting movement have a common, formed on the operating element projection or a nose and a corresponding, formed on the base part recess which in the starting position of the operating element in mutual overlap are arranged so that in the tilted position of the operating element of said projection is received in the associated recess and the sliding movement is thus blocked, while in the operating position, the projection is arranged outside the overlap with the recess and thus blocks the tilting movement of the operating element. As a result of this integral configuration of the blocking means, a particularly compact operating device can be created and the number of required components can be reduced.

The invention also relates to a motor vehicle, in particular a passenger car, with a movable component, in particular a sliding roof, and with an operating device according to the invention, which is designed to control the component.

The operating device 1 includes a control 2 , which on a support element 3 around a pivot axis 4 is pivotally mounted. The carrier element 3 thus contributes a total of the control 2 and is also (along with the control 2 ) on a base part 5 slidably mounted, which is designed as a housing.

The operating element 2 can be operated on four different operating modes: On the one hand, the control element 2 with respect to the carrier element 3 around the pivot axis 4 in a first tilt direction 6 as well as in a second opposite tilting direction 7 be tilted. On the other hand, the operating element 2 together with the carrier element 3 with respect to the base part 5 from the into the 1 and 2 shown starting position in a first sliding direction 8th and an opposite second sliding direction 9 be moved in a straight line. Overall, the operating element 2 So formed both as a toggle switch and as a slide switch.

As can be seen from the figures, the operating element 2 along the sliding direction 8th . 9 overall asymmetric design and on the one hand has a belly-like vault 10 and on the other hand a concave indentation 11 on. This indentation 11 extends toward the interior of the control 2 , so on the front of the control 2 a pointed nose 12 is formed, on which the operating element 2 can be pulled. Tilting the control 2 around the pivot axis 4 takes place by pulling the control element 2 on the nose 12 or by pressing the control element 2 on the belly-like vault 10 , Dragging turns the control 2 in the first tilt direction 6 tilted; by pressing the control element 2 in the opposite second tilt direction 7 tilted.

Both at the first tilt direction 6 as well as the second tilt direction 7 can each, for example, two tilt positions of the control 2 be provided, which are detected by means of a corresponding switching device. Also when moving the control 2 in the shooting directions 8th . 9 two actuating positions can be provided in each case, which can be detected by means of a separate switching device. The two switching devices are explained in more detail below.

To generate a haptic feedback or a haptic in the tilted positions and in the operating positions and in the starting position of the operating element 2 is a haptic device 13 provided according to 1 a first spring-loaded control cam 14 and an associated first control path 15 having. The first control cam 14 is on or in the carrier element 3 stored and thereby acted upon by a spring with a spring force which the control cam 14 against the tax train 15 suppressed. When moving the carrier element 3 in the shooting directions 8th . 9 slides the control cam 14 at the control track 15 and generates the haptic feedback in predetermined detent positions. These locking positions correspond to the operating positions or the starting position. The first control track 15 is at the base part 5 educated.

Referring to 2 includes the haptic device 13 also a second spring-loaded control cam 16 and an associated second control path 17 along which the second control cam 16 when tilting the operating element 2 is moved. The second control cam 16 is on the control 2 stored and acted upon by a spring force, which the second control cam 16 against the associated second control path 17 presses, so that the haptic feedback is generated in predetermined locking positions, which correspond to the tilted positions or the starting position. The second control track 17 is on the support element 3 educated.

The tax tracks 15 . 17 can be designed in the form of guides, in which the respective control cam 14 . 16 slidably guided is recorded. Alternatively, it may be at the guideways 15 . 17 also act on areas where the associated control cam 14 . 16 slides. In all embodiments, the respective guideway 15 . 17 Have depressions or recesses which define the said locking positions.

How out 3 A total of two first control cams can be made 14 . 14 ' be provided, which along respective control tracks 15 . 15 ' be moved to the haptic feedback when moving the carrier element 3 relative to the base part 5 to create. Both control cams 14 . 14 ' are acted upon by a spring force. For detecting the actuating positions when moving the operating element 2 along the sliding instructions 8th . 9 is a switching device 18 provided which, for example, two micro-switches 19 . 20 may include. These powerless microswitches 19 . 20 (no haptic function) are thus in the operating positions of the control 2 actuated, this operation is detected by a corresponding evaluation device which activates the associated function, in particular controls the sunroof accordingly.

4 shows a side view of the operating device 1 , Here is in particular the second control cam 16 and the associated second control path 17 recognizable, wherein also for the tilting movement of the operating element 2 a total of two such control cam 16 may be provided, which along the associated control track 17 to be moved.

To the tilting movement of the operating element 2 and thus to be able to detect the tilted positions, becomes a decoupling disk 21 used, which on the base part 5 around a pivot axis 22 is pivotally mounted. This pivot axis 22 Optionally also with the swivel axis 4 of the operating element 2 coincide. The decoupling disc 21 is plate-shaped and can when tilting the control 2 from one in 5 shown starting position in an active position according to 6 be moved, in which a switching device 23 is actuated, for example, a micro-switch. The decoupling disc 21 is doing by a driver element 24 moves, which on the control 2 is formed and projects laterally outwardly from this. This driver element 24 is in an elongated recess 25 the decoupling disc 21 added. This elongated recess 25 extends along the sliding direction 8th . 9 so when moving the control 2 in the sliding direction 8th . 9 the decoupling disc 21 remains in its initial position while the driver element 24 along the recess 25 emotional. Only when tilting the operating element 2 becomes the decoupling disc 21 through the driver element 24 quasi taken and moved into the active position, in which the switching device 23 is pressed. This is on the base part 5 arranged.

The blocking agents 26 have a first lead 27 or a nose on the side of the operating element 2 protrudes outwards and in the starting position of the operating element 2 in mutual overlap with a corresponding recess 28 is arranged, which in the base part 5 is trained. Accordingly, a second advantage 29 provided, which in the starting position of the operating element 2 in mutual overlap with an associated recess 30 is arranged, which on the base part 5 is trained. Will now be the control 2 in the first tilt direction 6 according to 8th tilted, the second projection arrives 29 in the assigned recess 30 , so a sliding movement in both sliding directions 8th . 9 is mechanically blocked. Becomes the operating element 2 in the opposite second tilt direction 7 tilted, the first lead passes 27 in the assigned recess 28 , so also the sliding movement of the operating element 2 is blocked. This is in 9 shown.

Becomes the operating element 2 however, in the first or second sliding direction 8th . 9 shifted, so are the tabs 27 . 29 outside the overlap with the associated recess 28 . 30 arranged, which in turn causes the tilting movement of the operating element 2 is prevented. This situation is in the 10 respectively. 11 shown.
