Definitions

  • the invention relates to an operating assembly for a motor vehicle, comprising an electrical switch, in particular for changing driving stages of an automatic motor vehicle transmission, wherein the switch comprises a first, manually operable lever, a second lever and an electrical switching element and wherein the first lever in its actuated state acts on the electrical switching element via the second lever.
  • Control modules with electrical switches are widely used in the field of motor vehicles. These are usually used to operate a radio, a navigation system and / or an on-board computer.
  • the electrical switches are preferably used in connection with automatic motor vehicle transmissions.
  • a driver can then manually change or select speeds of the automatic motor vehicle transmission via an electrical switch.
  • Such electrical switches for changing gears of an automatic motor vehicle transmission are part of a steering wheel assembly, they are often referred to as Heidelbergpaddel. The driver does not have to take his hands off the steering wheel for switching, so that he can safely maneuver the vehicle even during the operation of an electric switch.
  • control assemblies with electrical switches are known, which are used in Wegn techlelementen which are arranged in the center console of a motor vehicle.
  • An operating module of the type mentioned is known for example from DE 10 2012 014 019 A1. This control module has become larger It is important to note that the actuation path of a shift paddle is short and at the same time a fast and safe change of gears is possible.
  • the components of control modules of the type mentioned above are always manufactured while maintaining low tolerances.
  • the switching element actuating lever are manufactured with small tolerances to allow a durable and reliable operation of the switching element. If a switching element is actuated by a plurality of levers, a tolerance chain is created. In this case, it is necessary to tune the sum of the tolerances so that the switching element is not impaired in its function.
  • the object of the present invention is therefore to provide an operating assembly of the type mentioned, which is simple and reliable.
  • the control module should be inexpensive to produce.
  • an electrical switching element should be protected from overloading, z. As "Overtravel", be effectively protected.
  • the object is achieved by an operating assembly of the type mentioned, in which the second lever is a leaf spring with a firmly clamped end and a free end and actuation of the first lever, the leaf spring deformed such that it is at least partially displaced in the direction of the switching element , The leaf spring thus actuates the switching element.
  • the switching element may be any electrical component, in particular a micro-switch.
  • the switching element can, for. B. be arranged on a circuit board.
  • the control module is therefore simple.
  • the at least partially shift the leaf spring is limited by a stop.
  • the leaf spring exerts too much force on the electrical switching element or acts with an excessive actuation travel to the switching element.
  • the electrical switching element is thus protected against overloads, in particular in front of the "overtravel.” This results in an increased service life of the electrical switching element and thus of the entire control module. Thus, they are inexpensive to produce.

  • the stop is a projection on the support element.
  • the attack can be z. B. be a wall or post-shaped projection.
  • the leaf spring comprises a stiffened portion, which preferably faces the switching element.
  • the stiffened portion is stiff compared to the other portions of the leaf spring. This means that, when the leaf spring is acted upon, the other sections of the leaf spring first deform with a force.
  • the stiffened portion can thus be moved in a defined manner and, in particular, interact with the electrical switching element in a defined manner.
  • a bulging of the leaf spring is avoided in the region of the stiffened portion.
  • the stiffened portion is preferably between the tightly clamped end of the leaf spring and the stop. Thus, it is opposite to the switching element and the switching element is actuated by the stiffened portion. Thus, an overload of the switching element is effectively avoided.
  • the stiffened portion can be realized, for example, by a material thickening or by a material deformation.
  • the stiffened portion may include a tab which is angled about a substantially along the extension of the leaf spring oriented bending line, preferably angled substantially at right angles.
  • the tab is preferably angled on the side opposite to the switching element.
  • the leaf spring acts on the first lever with a restoring force in the direction of its unactuated state.
  • the restoring force results from an elastic deformation of the leaf spring in conjunction with the fixed clamping of one end of the leaf spring. It is thus biased the entire control module in an unactuated state.
  • the switching element is arranged in the direction of the extension of the leaf spring between the fixed clamped end and the free end of the leaf spring, wherein the switching element is preferably arranged closer to the fixedly clamped end. This results in a compact design of the control module.
