Description

Technical Field

[0001] The present invention relates to an actuation device for a vehicle, such as a door handle device. Background Technology

[0002] Actuation devices, such as door handle assemblies, are known, for example, at vehicle doors, rear panels, or hoods. Actuation devices for actuating or activating at least one vehicle function are known in the prior art. For example, door handle assemblies with a fixed door handle are known, wherein a door handle recess is provided below the grippable door handle. These door handle assemblies typically include a handle element that can be manually actuated to open the door, rear panel, or hood. Summary of the Invention

[0003] The object of the present invention is to provide an improved actuation device for a vehicle compared with the prior art, the actuation device being constructed to be compact and particularly enabling simplified actuation and operation of at least one vehicle function and simplified triggering or activation of the at least one vehicle function, such as a movable vehicle element, particularly a door.

[0004] The present invention achieves the above objective by means of an actuation device having the features of claim 1.

[0005] The actuation device for a vehicle according to the invention includes at least one detection unit and an actuating surface movable relative to the detection unit to actuate at least one vehicle function. The movable actuating surface has a magnetic component, and the detection unit includes at least one sensor unit. The sensor unit and the magnetic component are aligned such that actuation, particularly movement, of the actuating surface causes a change in the magnetic field, which can be detected by the sensor unit. The sensor unit is adapted to detect the change in the magnetic field caused by movement of the magnetic component, such as translational and / or rotational movement. The magnetic component is designed to be movable relative to the sensor unit when the actuating surface is actuated.

[0006] Actuation of the actuation device enables feasible vehicle functions, such as vehicle actions including unlocking and opening vehicle locks on movable vehicle components, such as door locks (e.g., electromechanical or electric locks), and / or starting and / or stopping the movement of movable vehicle components, such as doors, particularly electrically driven sliding doors. However, other vehicle functions can also be actuated, for example, upon customer request. The detection unit identifies the actuation and transmits the corresponding signal to the vehicle. A particular advantage of this invention is that additional cables, such as those used for conventional microswitches and / or buttons, are avoided. The actuation device according to the invention enables a compact structure with fewer parts and therefore lower cost. A single operation of the actuation device allows for simplified activation of at least one vehicle function.

[0007] The actuation device may be located on the exterior of the vehicle, such as at a door or pillar. The actuation device may be an integral part of the exterior of the vehicle. For example, the detection unit may be located on and / or within a carrier. The actuation surface may be designed to be separate from the detection unit and movable relative to the detection unit, such as relative to the carrier of the detection unit.

[0008] An improved embodiment of the actuation device is configured such that the movable actuation surface is adapted to cause the magnetic component to move together in the actuation direction during actuation.

[0009] An improved embodiment of the actuation device is configured such that the movable actuation surface is adapted to cause the magnetic component to rotate around a rotation axis during actuation.

[0010] An improved embodiment of the actuation device is configured such that the magnetic component includes at least one permanent magnet and / or a component that generates or influences the magnetic field.

[0011] An improved embodiment of the actuation device is configured such that the movable actuation surface includes at least one connecting element that is functionally connected to a magnetic component to move the magnetic component.

[0012] An improved version of the actuation device is configured such that the magnetic component is fixed at the connecting element.

[0013] An improved embodiment of the actuation device is configured such that the connecting element is adapted to move relative to the magnetic component and cause the magnetic component to rotate about a rotation axis when actuated on a movable actuation surface.

[0014] An improved embodiment of the actuation device is configured such that the sensor unit is arranged in a position that remains unchanged relative to the actuation surface within the detection unit.

[0015] An improved embodiment of the actuation device is configured such that a movable actuation surface is provided with a reset element.

[0016] An improved embodiment of the actuation device is configured such that the detection unit includes at least one evaluation unit connected to the sensor unit.

[0017] The actuating device may be designed as a door handle device, for example. The detection unit may be formed as a handle element or as a component of a handle element, for example. An embodiment of implementing the actuating device as a door handle device will now be described, in which the detection unit forms at least one handle element.

[0018] A door handle device for a vehicle, particularly an exterior door handle device, includes at least one handle element and an actuating surface movable relative to the handle element to unlock a door lock. The movable actuating surface has a magnetic component, and the handle element includes at least one sensor unit. The sensor unit and the magnetic component are aligned such that actuation, particularly movement, of the actuating surface causes a change in the magnetic field, which can be detected by the sensor unit. The sensor unit is adapted to detect the change in the magnetic field caused by movement of the magnetic component, such as translational and / or rotational movement. The magnetic component is designed to be movable relative to the sensor unit when the actuating surface is actuated.

[0019] A particular advantage of this invention is that additional cables, such as those used in conventional microswitches and / or buttons, are eliminated. The door handle device according to the invention enables a compact structure with fewer parts and therefore lower cost. A single operation of the door handle device simplifies both unlocking the door lock and opening the vehicle door.

[0020] The door handle assembly is designed to withstand the effects of the external environment to the greatest extent possible. The door handle assembly is designed to minimize wear and tear.

[0021] The actuating surface may be part of the actuating element. The actuating element may include a housing in which the actuating surface is held in a movably guided manner. The actuating element is configured to unlock a door lock, wherein the actuating element has at least one movable actuating surface, at which at least one magnetic component, such as a permanent magnet, and / or a component that generates or influences a magnetic field is arranged.

[0022] In one improved embodiment, different actuation stages and different actuation velocities of the actuated surface can be detected. For example, different actuation stages and actuation velocities can be detected using a sensor unit used to detect changes in the magnetic field.

[0023] The actuating surface is adapted, for example, to cause the magnetic component to move together in the actuation direction upon actuation. For example, the actuating surface can be pressed relative to the handle element in the direction of the door. The initial or normal state of the magnetic component can change relative to the handle element, particularly relative to a sensor unit disposed within the handle element. The magnetic component can perform linear movement, or in other words, be caused to move linearly, by actuation, particularly movement, of the actuating surface. The magnetic component and the actuating surface can be interconnected such that movement, e.g., linear movement, of the actuating surface causes movement, e.g., linear movement, of the magnetic component. The sensor unit is adapted to detect changes in the applied magnetic field caused by the movement, e.g., displacement or linear movement, of the magnetic component.

[0024] The sensor unit can be arranged and fixed in a position within the handle element. The handle element can be designed as a fixed door handle, particularly an exterior door handle. A door handle recess can be provided below the handle element that can be gripped by the user. The handle element can be arranged at a distance from the outer surface of the door. Alternatively, the fixed door handle forms a plane with the outer surface of the door, wherein the handle element is arranged in a door handle recess formed in the door, for example, behind the vehicle body. The handle element can be designed in the form of a handle panel that partially covers the door handle recess. The user's hand can be positioned in the door handle recess and below and / or behind the handle element to open the door. The handle element can be rigidly mounted on the vehicle.

[0025] The actuating surface, such as the upper or outer surface, may be flush with the outer surface of the handle element in the initial or normal state. The actuating surface may be located at one end of the handle element, such as the longitudinal end. The sensor unit is located at and / or within the end of the handle element facing the actuating surface. The distance between the magnetic component and the sensor unit and / or the distance between the end of the handle element and the actuating surface may vary depending on the sensor unit and / or magnetic component used.

[0026] In one improved embodiment, the actuating surface is adapted to cause the magnetic component to rotate about a rotation axis upon actuation. The initial or normal position of the magnetic component can change relative to the handle element, particularly relative to a sensor unit disposed within the handle element. For example, the actuating surface can be pressed relative to the handle element in the direction of the door. The magnetic component can rotate clockwise and counterclockwise. The initial or normal position of the magnetic component can change relative to the handle element, particularly relative to a sensor unit disposed within the handle element. The magnetic component can perform rotational movement, or rotation about a rotation axis, through actuation, particularly movement, of the actuating surface. The magnetic component and the actuating surface can be interconnected such that movement of the actuating surface, for example, linear movement, causes movement of the magnetic component, for example, rotational movement, or rotation about the rotation axis. The sensor unit is adapted to detect changes in the applied magnetic field caused by the rotation of the magnetic component about the rotation axis.

[0027] In an alternative improvement, the actuating surface can be designed to rotate about a rotation axis, and during actuation, particularly during movement, cause the magnetic component to move along with it. The magnetic component can be operatively connected to the actuating surface such that actuation of the actuating surface, such as linear or rotational movement, causes the magnetic component to move linearly with it, or to rotate the magnetic component about the rotation axis, or to cause a combination of rotation and linear movement of the magnetic component. The magnetic component can perform translational and / or rotational movement. The actuating surface can also be adapted to perform a combination of translational and rotational movement.

[0028] Another advantage is that this door handle mechanism enables the actuation of, for example, electrically operated door locks, particularly side door locks, via short-stroke actuation within the door handle mechanism. This reduces the force required to open movable vehicle components compared to vehicle components with key / lock door handle mechanisms known in the prior art. Movable vehicle components include, for example, doors, particularly side doors.

[0029] Furthermore, for users, it enables relatively quick and simple unlocking of door locks. In particular, it makes keyless unlocking of door locks possible. This reduces the time and effort spent searching for keys to open the locks. Moreover, it enables intuitive opening of movable vehicle components.

[0030] Furthermore, for example, by eliminating the key / lock function in the handle area of ​​movable vehicle components, the installation space for door handle devices is significantly reduced. Additionally, the visual appearance of movable vehicle components is improved by eliminating the keyhole.

[0031] In one improved embodiment, the magnetic component includes at least one permanent magnet and / or a component that generates or influences a magnetic field. The magnetic component may be designed as a permanent magnet or a so-called permanent magnet.

[0032] The actuating surface includes at least one connecting element that is functionally connected to a magnetic component to move the magnetic component. The connecting element may, for example, be connected to the actuating surface at one end and have a magnetic component at the opposite end.

[0033] Magnetic components can be directly or indirectly fixed to the connecting elements. The connecting elements can be connecting plates, connecting bridges, connecting walls, or other elements capable of connecting two structural components. Magnetic components can be fixed to the connecting elements via material-locking connections, form-locking connections, and / or force-locking connections.

[0034] Alternatively, the connecting element and the magnetic component can be designed as a single unit. The connecting element can be designed to be magnetized. For example, the connecting element may be at least partially provided with, for example, coated with a magnetic material. The connecting element may at least partially have at least one magnetic material, such as a paramagnetic or ferromagnetic material.

[0035] The magnetic component and the connecting element can be connected in such a way that movement of the actuating surface, for example, linear movement, causes movement of the connecting element and thus the magnetic component, for example, linear movement. The connecting element can be connected to the magnetic component in such a way that movement of the connecting element triggered via the actuating surface drives the magnetic component to move in the same actuation direction.

[0036] Alternatively, the connecting element and the magnetic component can be connected in such a way that when the actuating surface moves, the connecting element moves together, for example, linearly, wherein the movement of the connecting element causes rotation of the magnetic component. The connecting element can be connected to the magnetic component in such a way that the movement of the connecting element drives the magnetic component to perform rotational movement, particularly rotation about an axis of rotation. The connecting element is adapted, for example, to move relative to the magnetic component when the actuating surface is actuated and to cause the magnetic component to move, particularly rotate, about its axis of rotation. For example, the magnetic component is mounted in a movable manner, particularly in a rotatable manner, on the housing side of the housing of the actuating surface facing the handle element.

[0037] Alternatively, the connecting element and the magnetic component can be connected in such a way that actuation of the actuating surface causes a combination of rotational and linear movement of the magnetic component and / or the connecting element.

[0038] In one improved embodiment, the movable actuating surface is provided with a reset element. The reset element is, for example, a reset spring or a reset foam element. The reset element is adapted to cause the actuating surface to automatically reset from the actuated state to its initial state. Therefore, the reset force acts in the opposite direction to the actuation direction.

[0039] In one improved embodiment, the handle element includes at least one evaluation unit coupled to the sensor unit. The evaluation unit can be adapted to evaluate information detected by the sensor unit and trigger the door lock based on that information. Attached Figure Description

[0080] The same parts in all the accompanying drawings are indicated by the same reference numerals.

[0081] Figure 1The diagram schematically shows a front view of a vehicle element, such as a door 1 or a pillar, with an actuation device 7, such as a door handle assembly 2. The actuation device 7 may also be arranged on the outer surface of the pillar. For example, the actuation device 7 may be flat and / or flush with the vehicle body.

[0082] For better understanding, coordinate systems are shown in the figures, where the vertical axis X corresponds to the longitudinal direction, the horizontal axis Y corresponds to the transverse direction, and the vertical axis Z corresponds to the vertical direction, based on the vehicle (not shown in detail) and / or based on door 1.

[0083] The actuation device 7 is located on the outer side 11 of the vehicle. The actuation device 7 includes a detection unit 71 located on the outer side 11 of the vehicle and an actuation element 22 for actuating vehicle functions, such as actuating the unlocking and / or opening of door locks (not shown in detail), or actuating the start and stop functions of movable vehicle components, such as doors 1, especially sliding doors, or rear panels or hoods.

[0084] Actuating element 22 is also arranged on the outer side 11 of the vehicle. For example, actuating element 22 includes a housing 22.1 and an actuating surface 22.5. Alternatively, actuating device 7 may be an integral part of the outer side 11 of the vehicle. For example, detection unit 71 and actuating element 22 may be an integral part of the outer side 11 of the vehicle, and only actuating surface 22.5 may be designed to be separate from detection unit 71 and movable relative to the detection unit, for example relative to the carrier 72 or housing of the detection unit 71, particularly relative to the bottom of the carrier or the bottom of the housing of the detection unit 71.

[0085] In one improved embodiment, the actuating element 22 and the detection unit 71 may be arranged to be recessed at and / or within the outer side 11 of the vehicle. The actuating element 22 may be arranged, for example, retracted within the door 1. The door 1 may have, for example, a retracted recess, in which the actuating device 71 may be arranged, for example, recessed. The recess may, for example, be partially covered by the detection unit 71. The actuating element 22 is designed to be separate from the detection unit 71. The actuating element 22 is arranged at a distance from one end of the carrier 72 of the detection unit 71.

[0086] The actuation device 7, which is designed as the door handle device 2, will be described next.

[0087] The door handle assembly 2 is located on the outer side 11 of the vehicle. The door handle assembly 2 includes a handle element 21 located on the outer side 11 of the vehicle and an actuation element 22 for unlocking a door lock (not shown in detail).

[0088] The actuating element 22 is also arranged on the outer side 11 of the vehicle. For example, the actuating element 22 includes a housing 22.1 and an actuating surface 22.5.

[0089] In one improved embodiment, the actuating element 22 and the handle element 21 may be arranged to be recessed at and / or within the outer side 11 of the vehicle. The actuating element 22 may be arranged, for example, retracted within the door 1. The door 1 may have, for example, a retracted handle recess partially covered by the handle element 21. For example, the handle element 21 may be designed as a fixed handle. The actuating element 22 may be designed to be separate from the handle housing of the handle element 21. The actuating element 22 may be arranged at a distance from one end of the handle element 21. Alternatively, the actuating element 22 may be an integral part of the handle element 21, and only the actuating surface 22.5 may be designed to be separate from the handle element 21 and movable relative to the handle element and handle housing, particularly movable relative to the handle bottom 24.

[0090] Figure 2 The diagram schematically shows a vehicle component, such as a side view of a door 1, with an actuating device 7 designed as a door handle device 2.

[0091] The housing 22.1 is designed, for example, in the form of a cap. The housing end 22.2 of the housing 22.1 is fixed to the outer side 11 of the vehicle. The second housing end 22.3, opposite to the first housing end 22.2, points towards the vehicle's surroundings and is, for example, positioned at the height of the handle element 21. An actuating surface 22.5, such as the upper surface or outer surface 23 of the actuating surface 22.5, may be flush with the outer surface 215 of the handle element 21 in either the initial or normal state.

[0092] The cross-section of housing 22.1 is generally U-shaped. Housing 22.1 includes, for example, at least one housing bottom 24 and at least one housing wall portion 25 protruding from the housing bottom 24. Housing 22.1 may be designed as a single piece. For example, housing 22.1 may be an injection molded part. Housing 22.1 may also be designed as a split piece, wherein the housing bottom 24 and housing wall portion 25 may be connected to each other, for example, by material locking, force locking, and / or form locking.

[0093] The housing 22.1 includes a receiving space 22.4, which may be in the form of an empty space, cavity, or internal space. The actuating element 22 further includes a movable actuating surface 22.5 disposed in the region of the housing end 22.3. In the initial state, particularly the normal state and the unacted state, the outer side of the actuating surface 22.5, particularly the outer surface 23, is flush with the housing end 22.3. The actuating surface 22.5 is arranged to be movable within the receiving space 22.4 in a direction toward the outer side 11 of the vehicle, or in a direction toward the inner housing end 22.2. For example, the actuating surface 22.5 is guided and held. For example, the actuating surface 22.5 is linearly actuated, for example, pressable.

[0094] For example, the actuating surface 22.5 is actuable, specifically movable, in a first actuation direction, which is marked with arrow PF1. The actuating surface 22.5 can move spontaneously in a second direction opposite to the actuation direction PF1, which is marked with arrow PF2. The actuating surface 22.5 can move spontaneously from an actuated state to an initial state.

[0095] Furthermore, the actuating element 22 includes a reset element 22.6 disposed within the receiving space 22.4. The reset element 22.6 is, for example, a reset spring or a foam element designed to be reversibly flexible and / or elastic and / or deformable. The reset element 22.6 is supported within the receiving space 22.4 at the inner end of the housing 22.2 and is coupled to the inner side of the actuating surface 22.5. The reset element 22.6 is adapted to move against its spring force in the direction of arrow PF1 when the actuating surface 22.5 is actuated, for example, when the actuating surface is pressed inward, and to reset to its raised state in the direction of arrow PF2 when the actuating surface 22.5 is not actuated, particularly when or after the actuating surface is released.

[0096] A magnetic component MK, such as a permanent magnet 3 and / or a component 4 that generates or influences a magnetic field, is arranged on the inner side of the actuating surface 22.5. The magnetic component MK may be formed, for example, at least partially, of a ferromagnetic material, such as iron, cobalt, and / or nickel.

[0097] The magnetic component MK may include a permanent magnet 3 or a permanent magnet. The magnetic component MK is, for example, a magnet or a coil.

[0098] Alternatively or optionally, the magnetic component MK may additionally include a component 4 that generates or influences a magnetic field. The component 4 influencing the magnetic field is, for example, made of a material capable of influencing a magnetic field. This material is, for example, a ferromagnetic material. The component 4 is, for example, coated with a ferromagnetic material.

[0099] For example, the magnetic component MK is arranged in the receiving space 22.4. For example, the permanent magnet 3 and / or component 4 are arranged in the receiving space 22.4.

[0100] The magnetic component MK is arranged in the housing 22.1 on the housing side 26 opposite to the handle element 21.

[0101] According to Figure 2 and Figure 3In this embodiment, the magnetic components MK, such as permanent magnets 3 and / or components 4, are held inside the actuating surface 22.5 via additional connecting elements 5 and / or coupling elements, for example, fixed there by means of material locking, force locking, and / or form fitting. The connecting element 5 is, for example, a retaining device and / or a retaining foam and / or a retaining adhesive. The connecting element 5 is arranged together with the magnetic components MK, such as permanent magnets 3 and / or components 4, in the receiving space 22.4. When the actuating surface 22.5 moves, the connecting element 5 and the magnetic components MK, such as permanent magnets 3 and / or components 4, are able to move together in the directions of arrows PF1 and PF2.

[0102] The handle element 21 and / or detection unit 71 includes an electronic unit 211. The handle element 21 and / or detection unit 71 is fixed to the exterior 11 of the vehicle and has a handle recess 212 for user use.

[0103] Electronic unit 211 includes sensor unit 213 and evaluation unit 214 connected to sensor unit 213. Sensor unit 213 is designed, for example, as an inductive sensor or a Hall sensor. Evaluation unit 214 is connected, for example, to a door lock and / or to a control unit that triggers the door lock and / or to a control unit capable of activating another vehicle function.

[0104] Sensor unit 213 and magnetic components MK, such as permanent magnet 3 and / or component 4, are aligned such that actuation, particularly movement, of actuating surface 22.5 causes a change in the magnetic field, which can be detected by sensor unit 213. In the initial state, sensor unit 213 and permanent magnet 3 and / or component 4 are aligned substantially parallel to each other. The displacement of actuating surface 22.5 and therefore permanent magnet 3 and / or component 4 relative to sensor unit 213 causes a change in the magnetic field at sensor unit 213, which is detected or measured by the sensor unit.

[0105] Sensor unit 213 can detect this change in the magnetic field and transmit the corresponding signal to the associated evaluation unit 214. Evaluation unit 214 processes the signal and evaluates it, for example, whether an actuation has occurred, so as to subsequently trigger the door lock and / or control unit to unlock the door lock and / or actuate another vehicle function.

[0106] After the actuating element 22 actuates and unlocks the door lock, the user can open the door 1 at the handle element 21. The actuating surface 22.5 is returned to its initial state by the reset element 22.6 without the user applying any force.

[0107] In one improved embodiment, the door lock can also be engaged, for example, by actuating the actuating element 22. For example, the actuating element 22 is designed to have a so-called toggle function.

[0108] In one improved embodiment, the displacement of an electrically driven door 1, such as a sliding door, can be started and stopped by actuation of the actuating element 22.

[0109] Figure 3 A cross-sectional view schematically showing a further embodiment of the actuation device 7 according to the invention is shown, which may be, for example, a door handle device 2.

[0110] For example, the actuating surface 22.5 has a vertically inwardly projecting connecting element 5 into the receiving space 22.4, at which a magnetic component MK, such as a permanent magnet 3 and / or component 4, is arranged. The connecting element 5 and the actuating surface 22.5 are designed, for example, to be integral. The connecting element 5 is arranged on the housing side 26 of the actuating element 22 facing the handle element 21 and / or the detection unit 71, particularly the carrier 72 of the detection unit.

[0111] The connecting element 5 can exist as a separate structural component. The connecting element 5 can, for example, be connected at one end to the actuating surface 22.5 and at the opposite end to the magnetic component MK.

[0112] The magnetic component MK can be directly or indirectly fixed to the connecting element 5. The connecting element 5 can be a connecting plate, connecting rod, connecting wall, or other element capable of connecting two structural components. The magnetic component MK can be fixed to the connecting element 5 via a material-locking connection, a form-locking connection, and / or a force-locking connection.

[0113] Alternatively, the connecting element 5 and the magnetic component MK can be designed as a single unit. The connecting element 5 can be designed to be magnetized. For example, the connecting element 5 can be at least partially provided with, for example, a magnetic material coated on it. The connecting element 5 can at least partially have at least one magnetic material, such as a paramagnetic or ferromagnetic material.

[0114] The magnetic component MK and the connecting element 5 are connected in such a way that movement of the actuating surface 22.5, for example linear movement, causes the connecting element 5 and thus the magnetic component MK to move, for example linear movement.

[0115] Figure 4 A simplified cross-sectional view of a further embodiment of the actuation device 7 according to the invention, such as a door handle device 2, is schematically shown.

[0116] For example, the magnetic component MK is designed in the form of a turntable. For example, the permanent magnet 3 and / or component 4 are designed in the form of a turntable. For example, the magnetic component MK is mounted in a manner that allows it to rotate about a rotation axis D. The rotation axis D may, for example, be functionally connected or coupled to a connecting element 5.

[0117] For example, the rotating shaft D is formed by a bearing element 6 mounted in a rotatable manner. The bearing element 6 is, for example, a bolt or pin. The magnetic component MK is connected to the bearing element 6 such that rotation of the bearing element 6 about its own axis causes rotation of the magnetic component MK. Movement of the connecting element 5, for example, causes movement of the bearing element 6 and thus causes movement, particularly rotation, of the magnetic component MK.

[0118] For example, the bearing element 6 and the magnetic component MK are connected and / or movably connected to the actuating surface 22.5 via a coupling (not shown in detail), such as a mechanical coupling. The connecting element 5 and the magnetic component MK can be connected to each other via the coupling. The coupling can be, for example, a toothed connection or a friction connection. Movement of the connecting element 5 causes movement of the magnetic component MK around the bearing element 6 and thus around its axis of rotation D.

[0119] The connecting element 5 and the magnetic component MK are connected in such an interactive manner that movement of the connecting element 5 causes rotation of the magnetic component MK, wherein, when the actuating surface 22.5 moves, the connecting element 5 moves together, for example, linearly together. The connecting element 5 is adapted, for example, to move relative to the magnetic component MK when the actuating surface 22.5 is actuated. The movement of the connecting element 5 is converted into rotational movement of the magnetic component MK.

[0120] Figure 5 schematically shown Figure 4 A view of the actuating device 7 shown, such as the actuating element 22 of the door handle device 2.

[0121] The connecting element 5 is connected at one end to the actuating surface 22.5 and is functionally connected at the opposite end to the magnetic component MK. For example, the connecting element 5 and the magnetic component MK may be connected to each other via a functional coupling, such as a toothed coupling or a friction coupling.

[0122] The connecting element 5 and the magnetic component MK are connected in such an interactive manner that movement of the connecting element 5 causes rotation of the magnetic component MK, wherein, when the actuating surface 22.5 moves, the connecting element 5 moves together, for example, linearly together. The connecting element 5 is adapted, for example, to move relative to the magnetic component MK when the actuating surface 22.5 is actuated. The movement of the connecting element 5 is converted into rotational movement of the magnetic component MK.

[0123] The magnetic component MK is rotated in the direction of arrow PF3 or PF4 via connecting element 5 and mechanical coupling by actuation of actuating surface 22.5, wherein sensor unit 213 detects the change in magnetic field caused by rotation. To reset, the magnetic component MK is reset in the opposite direction, specifically by rotation.

[0124] Figure 6A simplified cross-sectional view of a further embodiment of the actuation device 7 according to the present invention is shown schematically.

[0125] In the illustrated embodiment, the magnetic component MK can be moved in the opposite direction (e.g., according to arrow PF3) to the actuation direction (e.g., according to arrow PF1) by actuation of the actuation surface 22.5. This can be achieved, for example, via the rotation axis D.

[0126] For example, the magnetic component MK is designed as a pivotable lever. For example, the permanent magnet 3 and / or component 4 are designed as pivotable levers. For example, the connecting element 5 can be designed as a lever element.

[0127] The magnetic component MK is connected, for example, to the connecting element 5. The connecting element 5 is, for example, capable of pivoting about the rotation axis D, wherein the pivoting of the connecting element 5 causes the pivoting of the magnetic component MK.

[0128] In the initial state, i.e., in the unacted state, the connecting element 5 and / or the magnetic component MK can extend substantially perpendicular to the transverse axis y. In the initial state, the connecting element 5 and / or the magnetic component MK extend substantially parallel to the actuating surface 22.5. The magnetic component MK is provided at the end of the connecting element 5 facing the detection unit 71. The end of the connecting element 5 opposite to the magnetic component MK contacts the end of the actuating surface 22.5 such that movement of the actuating surface 22.5 causes the connecting element 5 to pivot about the rotation axis D. The movement of the connecting element 5 causes the magnetic component MK to move together. When the actuating surface 22.5 is actuated, the actuating surface presses against the corresponding end of the connecting element 5.

[0129] In other words, the linear movement of the actuating surface 22.5 causes the rotational movement of the magnetic component MK and / or the connecting element 5.

[0130] For example, the rotating shaft D is formed by a bearing element 6 that is mounted in a rotatable manner. The bearing element 6 is, for example, a bolt or a pin.

[0131] Actuation of the actuating surface 22.5 causes the magnetic component MK to rotate in the direction of arrow PF3 via the connecting element 5, where the sensor unit 213 detects the change in the magnetic field caused by the rotation. A reset element 22.6 is provided to reset the actuating surface 22.5. This involves moving the actuating surface 22.5 in the opposite direction to the actuation direction according to arrow PF1. The actuating surface 22.5 no longer applies actuating force to the connecting element 5, thereby resetting the connecting element 5 and the magnetic component MK in the direction according to arrow PF4, specifically by rotation. For example, the rotation shaft D is spring-loaded.
