Definitions

  • the invention relates to an emblem actuator, in particular for a motor vehicle, having the features specified in the preamble of claim 1.
  • An emblem actuator for a motor vehicle is known from the prior art. These are usually mounted on a movable part, such as a tailgate or a hood, to enable a user to open the movable part. The opening is triggered by an electrical switch, which emits an electrical switching signal depending on the user's actuation.
  • sealing such switches is often complex, particularly in the exterior of the vehicle.
  • the emblem actuators are sometimes arranged in a recess in the vehicle's sheet metal. It is therefore desirable to design the actuating devices as compactly as possible, in particular as flat as possible.
  • the emblem actuator should be as flush as possible with the vehicle's outer skin. for aesthetic and aerodynamic reasons, flush with the surface.
  • an electromagnetic switch is arranged on the housing part of such emblem actuators that is fixed to the vehicle.
  • an activation device made of metal is usually integrated there, especially in the case of an electromagnetic switch, in order to trigger the switch.
  • the object of the present invention is to at least partially remedy the above-mentioned disadvantages known from the prior art.
  • the object of the invention is to improve the comfort, in particular the feel, when activating an emblem for the user.
  • the arrangement of the activation means according to the invention on the reset means or at least partially within the reset means makes it possible to mount the emblem element separately from the housing of the emblem actuator on the vehicle, in particular on a bonnet or on a tailgate. Another advantage is also achieved in that the emblem element with different manufacturer logos can be used on the same housing.
  • the reset means the The activation means is stored at a reliable distance from the electrical component, with a return means made of a compressible material being provided for moving the activation means from an actuation position to a basic position.
  • the activation means is held in a predetermined assembly position.
  • the activation means can be held in the predetermined position by form-fitting.
  • the activation means can be inserted into a complementary recess in the return means.
  • the return means is made of foam, it is possible to overmold the activation means in the foam or to insert it laterally into an insert-like recess parallel to the electrical component. It is also conceivable to attach the activation means to the return means using a liquid material, in particular by gluing. This has the advantage that the distance between the activation means and the electrical component, in particular in the form of an inductive or capacitive sensor, can be reliably measured in order to sense an actuation signal.
  • a bearing element made of a compressible material can be assigned to the emblem element for moving the emblem element.
  • a gap is provided for an actuation stroke of the emblem element.
  • the compressible material is arranged in the gap. This has the advantage that, for example, no ice can get into this gap, which could impair the actuation process.
  • the compressible material ensures that the Emblem element is returned to its basic position after activation.
  • the emblem element is intended for arrangement in the external area of the vehicle part, in particular in the form of a tailgate or a hood, in a recess and the housing is intended for arrangement in the internal area of the vehicle part, in particular in the form of a tailgate or a hood.
  • the emblem actuator can be arranged essentially flush with the vehicle outer skin for aesthetic and aerodynamic reasons, since by separating the emblem element from the housing, the emblem element is arranged in a recess in the vehicle sheet metal in the external area of a hood or on a tailgate with limited installation space and the housing is arranged in an internal area protected from environmental influences, in which there is comparatively more installation space.
  • the invention can provide in the emblem actuator that the return means and/or the bearing element is designed to retain its elastic properties down to at least minus 40 degrees Celsius, preferably down to minus 70 degrees Celsius, in order to ensure the actuation of the electrical component with the emblem element.
  • the elastic material can be made of a foam, which preferably comprises a cellular rubber.
  • the foam has the positive property that it can remain deformable even at low temperatures of less than or equal to minus 40 degrees Celsius, because the cellular structure provides enough space to compress the foam. This ensures safe and flawless operation of the emblem element and the good feel.
  • the emblem actuator is also retained during operation.
  • the invention can provide for the emblem actuator, the return means, the electrical component and the activation means within the housing to be at least partially enclosed by a potting compound.
  • the potting compound is poured into the housing and bonds with the components arranged there. This has the advantage that the tightness of the emblem actuator and the fastening of the components in the housing are improved.
  • the design of the actuation module can be further improved if the potting compound comprises the restoring means, in particular in the form of an elastic material, whereby the potting compound can comprise a one-component silicone compound.
  • the one-component silicone compound is liquid in its raw state and is therefore intended for potting electrical components. It is preferably used for general adhesive and sealing purposes.
  • the one-component silicone compound has another important property, namely that the potting compound cannot harden at temperatures of up to minus 70 degrees Celsius.
  • the one-component silicone compound is therefore ideally suited for use with components that are exposed to high temperature fluctuations.
  • the one-component silicone compound ensures that the activation element, which is at least partially embedded in the potting compound, can still be actuated even at very low temperatures of up to minus 70 degrees Celsius, because the potting compound retains its elastic properties even at these temperatures in order to allow the activation element to move.
  • the invention can provide for the emblem actuator that the emblem element has a fastening means, wherein the housing has a complementary fastening counter-measure.
  • the fastening serves to fasten the emblem element to the housing.
  • Two, preferably round fastening domes are provided on the emblem element, which can be mounted in the fastening openings formed on the housing.
  • the housing is arranged in a fixed position in the inner cavity of the vehicle part and the emblem element is connected to the housing from the outside.
  • the emblem element can only move in the direction of the electrical component or the activation means.
  • a loss protection device in particular in the form of safety hooks, is formed, which grip behind the housing when installed.
  • the emblem actuator can provide that the fastening counter-means of the housing has a first fastening bearing and a second fastening bearing, wherein the activation means is designed as an elongated element and is arranged with one end on the first fastening bearing and the other end on the second fastening bearing.
  • the activation means is designed as a spring plate made of metal. The use of the spring plate has the advantage that it is temperature-resistant. By actuating a plunger formed in the emblem element, the spring plate is deformed essentially in the middle to trigger a switching signal. When the spring plate is no longer loaded, the spring plate ensures that the activation element is returned to its original position.
  • the emblem actuator can be designed to be very compact and cost-effective if the fastening countermeasure is provided both for fastening the emblem element and for fastening the activation element.
  • the emblem actuator can be designed to be very compact and reliable if the electrical component is designed as a capacitive switching element or as an inductive switching element.
  • the invention can provide for the emblem actuator that the electrical component, the capacitive switching element, comprises a first electrode and the capacitive switching element is assigned a second electrode, wherein the activation means is designed as the second electrode. This allows the device outlay to be further reduced.
