Definitions

  • the invention is based on an actuator according to the preamble of claim 1.
  • Such actuators such as electrical and / or electronic switching devices designed in the manner of a joystick and / or cursor switch, are used for the manual control and / or triggering of functions in a motor vehicle.
  • switching devices are used by a user to input data for an electrical device, for example in car radios, navigation devices, on-board computers, etc.
  • Such an actuator has a handle that can be designed, for example, in the manner of an actuating lever or actuating button.
  • the handle can be moved manually by the user and interacts with a displacement means. Because of this interaction of the handle with the displacement means, the handle can be displaced in a displacement plane in at least one direction from a neutral position into a displacement position.
  • a haptic can be provided for the handle, which is formed by mechanical means, for example a ball catch. Such mechanical haptics are complex.
  • the invention is based on the object of providing an actuator with a simply configured haptic.
  • an actuator with a magnetic haptic is to be created.
  • this object is achieved by the characterizing features of claim 1.
  • a magnet and a magnetizable element are provided.
  • the magnet interacts with the magnetizable element in such a way that the magnetic force between the magnet and the magnetizable element when moving the displacement means generates a haptic in the direction of the displacement position and / or a restoring force in the direction of the neutral position for the handle.
  • a special ergonomics for the actuator is achieved with simple means.
  • the displacement means in the displacement position can act on an electrical switching element, a sensor or the like in order to generate a signal.
  • the signal which acts in particular in the manner of a switching signal, can be used to control and / or trigger the assigned functions.
  • the magnet can expediently be fixed in the tappet at one end of the tappet in such a way that the magnet protrudes from the tappet.
  • the protruding part of the magnet can rest on the magnetizable element in a simple manner.
  • the other end of the plunger can in turn be held tiltably in an opening of the displacement means.
  • the magnet can be designed prismatically with a rectangular cross section, specifically preferably cube-shaped with a square cross section.
  • the magnetizable element can be designed in a simple manner as a strip-shaped sheet metal.
  • the haptics and / or the restoring force can be generated in two mutually perpendicular directions for the movement of the handle.
  • a housing can be provided to protect against external, negative influences such as dust, dirt, water or the like.
  • the handle can expediently protrude from the housing in a manually accessible manner and / or the displacement means can be located in the interior of the housing.
  • the magnetizable element can be arranged immovably in the interior of the housing,
  • the rotary knob can be pushed into four positions via a linear XY shift. Both modes of operation are implemented using magnetic haptics.
  • the magnet is fixed in a plunger for turning. This stands on a magnetizable material. The slide in which the plunger is mounted is moved when it is pushed. The plunger then tilts over an edge and thereby creates the feel. The reset is generated by the attraction of the magnet. Since the magnet is square, this works in the X and Y directions as well as in the + and - directions,
  • a special haptic can be generated by means of the permanent magnets for a sliding and / or tilting function of the handle. Furthermore, the haptics are generated in a contactless manner, so that the actuator can be operated without wear.
  • the actuator offers good ergonomics and is nevertheless designed in a simple manner, so that the actuator is inexpensive.
  • FIG. 1 shows an actuator with a displaceable and / or rotatable handle in a perspective view
  • FIG. 2 shows the actuator from FIG. 1 in a cut-away view
  • FIG. 3a shows a detail from FIG. 2, the handle being in the neutral position
  • FIG. 3b shows the detail section according to FIG. 3a, the handle being in the shifted position
  • FIG. 4 shows a further cut-away view of the actuator from FIG. 1,
  • FIG. 5a shows a rotating means consisting of a stator and a rotor for the actuator from FIG. 4 as an individual part, FIG.
  • FIG. 5b shows the rotor from FIG. 5a as an individual part in a perspective view
  • FIG. 5c individual parts of the rotor and the stator from Fig. 5a in a schematic representation
  • FIG. 6b shows individual parts of the rotor and the stator from FIG. 6a in a schematic illustration.
  • 1 shows an actuator 1 which is used for manual control and / or triggering of functions in a motor vehicle.
  • the actuator 1 can be a door control unit located in the driver's side door of the motor vehicle, with the aid of which the user can adjust the exterior mirrors of the motor vehicle by an electric motor.
  • the actuator 1 has a housing 2 from which a handle 3 protrudes manually accessible to the user.
  • the manually movable handle 3 interacts with a displacement means 4 shown in FIG. 2 in such a way that the flange handle 3 can be displaced in a displacement plane in at least one direction 5 from a neutral position into a displacement position.
  • the flange handle 3 can be moved into further displacement positions in a further direction 6, which is essentially perpendicular to the direction 5, as can be seen from FIG. 1.
  • a magnet 7 and a magnetizable element 8 are provided for the actuator 1.
  • the magnet 7 interacts with the magnetizable element 8 in such a way that the magnetic force between the magnet 7 and the magnetizable Element 8 generates a haptic in the direction of the displacement position for the handle 3 when the displacement means 4 is displaced.
  • the user has to overcome the magnetic force acting between the magnet 7 and the magnetizable element 8 in the neutral position in order to move the handle 3 into the displacement position, which the user perceives as haptics and ergonomically in a special way.
  • the magnetic force acts when the handle is in the shifted position
  • the displacement means 4 acts in the displacement position on a merely schematically shown in FIG.
  • the magnet 7 is prismatic with a rectangular cross section.
  • the magnet 7 is cube-shaped with a square cross-section.
  • the magnetizable element 8 is designed as a strip-shaped sheet metal.
  • the displacement means 4 is designed symmetrically with respect to the handle 3, so that a plunger 11 with magnet 7 and a magnetizable element 8 are located both on the left-hand side of the handle 3 in FIG.
  • the actuator 1 will be described in more detail as a rotary encoder in the manner of a rotary encoder for manual control and / or triggering of functions in a motor vehicle with reference to FIG. see Fig. 1) manually rotatable.
  • the handle 3 interacts with the rotating means 13 in such a way that the handle 3 can be rotated into at least one rotational position in the manner of a latching position.
  • the handle 3 can preferably be rotated into several successive rotary positions.
  • a magnet 14 and a further magnet 15 are provided. Instead of a further magnet 15 or in addition, a magnetizable element can also be provided, but this is not further shown here.
  • the magnet 14 interacts with the further magnet 15 or the magnet 14 interacts with the magnetizable element in such a way that the magnetic force between the magnet
  • the rotating means 13 acts on an electrical switching element 9, shown only schematically, a sensor or the like, in order to generate a signal.
  • the signal is then used in the form of a switching signal to control and / or trigger the assigned functions in the motor vehicle, for example to select the corresponding exterior mirror.

Abstract

La présente invention concerne un actionneur (1) destiné en particulier à la commande et/ou l'activation manuelle de fonctions dans un véhicule automobile. L'actionneur comprend une poignée qui peut être déplacée manuellement (3) et un moyen de déplacement (4), la poignée (3) interagissant avec les moyens de déplacement (4) de telle sorte que la poignée (3) peut être déplacée dans un plan de déplacement dans au moins une direction hors d'une position neutre dans une position de déplacement. Un aimant (7) et un élément magnétisable (8) sont prévus pour l'actionneur. L'aimant (7) interagit avec l'élément magnétisable (8) de telle sorte que la force magnétique entre l'aimant (7) et l'élément magnétisable (8) génère une rétroaction haptique dans la direction de la position de déplacement et/ou une force de rappel dans la direction de la position neutre pour la poignée (3) lorsque le moyen de déplacement (4) est déplacé.
