Definitions

  • the invention relates to a holding frame for a carrier element of a sensor in a motor vehicle, the sensor being held in surface contact with an inside of a pane of the motor vehicle.
  • sensors In order to simplify operation and increase well-being, it is common today in motor vehicles to use sensors with which, for example, the temperature, the light conditions or the precipitation can be detected.
  • the climatic conditions in the motor vehicle In addition to the external weather influences to which the motor vehicle is exposed, it is also common to record the climatic conditions in the motor vehicle and to measure corresponding, predeterminable values which influence the room climate, such as the interior temperature, using this measured value for the air conditioning system and to regulate it.
  • sensors In order to record the external influences on the motor vehicle and the data relating to the interior of the motor vehicle, such sensors are often attached to the inside of the windshield. An incipient precipitation can then be detected through the pane, for example, and the interior temperature measured simultaneously with a temperature sensor.
  • Such sensors are generally known and described.
  • the senor has a sensor housing in which a capacitive sensor is integrated, one of the two electrodes of the sensor being held by the sensor housing in such a way that this electrode is flush with the pane.
  • the housing has a thin film for thermal connection to the pane and to compensate for the pane curvature.
  • the film has a high thermal conductivity and good adhesion.
  • an aluminum oxide with adhesive portions is provided here, so that the underside of the sensor can be glued flush to the pane.
  • a detector is known from EP 0 723 897 B1, by means of which water can be detected on the outside of a glazing, in particular a laminated glass pane.
  • the ultrasound detector described in this document is glued to the glazing using an adhesive film.
  • Another sensor which is also glued to a surface by means of a thermally conductive adhesive, is known from EP 0 613 000 B1. All of these sensors have the disadvantage that if the carrier material is damaged, the carrier material in the exemplary embodiments being a windshield, the sensor is connected to the pane in an almost undetachable manner. When replacing a pane, the sensor must also be replaced, since it is connected to the pane or could at least be damaged or destroyed when detached from the pane due to its very fine internal structure. This means not only costs for a new pane, but also for the very high-quality sensor.
  • the object of the invention is to provide a way to overcome the disadvantages of the prior art and to detachably attach the sensor to the pane.
  • the object according to the invention is achieved by a holding frame for a carrier element of a sensor in a motor vehicle, the holding frame having a flat underside that can be glued to a pane of the motor vehicle and having an opening with at least one contact surface for the carrier element in which the carrier can be positioned flat to the disk and against the contact surface and with a spring element, by means of which a force can be applied to the carrier element.
  • the holding frame designed according to the invention offers the possibility of pressing the sensor directly onto the pane, so that an optimal connection of the sensor to the pane is guaranteed.
  • An opening is provided in the holding frame, which provides at least one contact surface in order to position the sensor horizontally. This ensures easy and precise mounting of the carrier element in the holding frame.
  • FIG. 1 shows a holding frame with an inserted carrier element and a spring element as an extension
  • FIG. 2 shows a holding frame with a spring element as a spring bar
  • FIG. 3 shows a holding frame with a spring element as a spring bar with an inserted support frame
  • FIG. 4 shows a shaped sheet for forming a composite component
  • FIG. 5 a shaped sheet with an inserted carrier element
  • FIG. 6 is a molded sheet molded with plastic or metal as a composite component
  • FIG. 7 a holding frame with shaped sheet and inserted carrier element
  • Figure 8 is a molded sheet with an alternative support member and Figure 9 shows a holding frame with molded sheet and inserted alternative carrier element.
  • the holding frame 1 shows a holding frame 1 with an inserted carrier element 2 and an extension 3 integrally molded on the holding frame 1.
  • the holding frame 1 has a flat underside 4 and a contact surface 5 against which the support element 2 can be positioned during assembly.
  • protrusions 6 are provided on the holding frame 1, by means of which the carrier element 2 can be clamped in the holding frame 1.
  • a connecting element 7 is integrally formed on the carrier element 2, the connecting element 7 in this embodiment being designed as a socket for a plug.
  • the carrier element 2 also has openings 8 which make it possible for a sensor held in the carrier element 2 to also record measured values in the interior of the vehicle. In this embodiment, the sensor element is not shown. In this case, the sensor element would rest directly on the pane below the carrier element 2 in the regions 9 and 8.
  • the sensor can be seated directly on the pane or connected to the pane by means of a thin film.
  • the film is used for thermal coupling and, on the other hand, tolerance compensation with regard to the curvature of the pane is possible.
  • Struts 10 are provided for stiffening the holding frame 8, only one strut 10 being provided with a reference symbol for better clarity in FIG.
  • the holding frame 1 has a closed shape in this embodiment and extends around the entire support element 2. This has the advantage that the holding frame 1 retains its shape when glued to the windshield and that the carrier element 2 can be mounted very easily and in a precise position.
  • An extension 3 is integrally formed on the holding frame 1, which can be partially brought over the carrier element 2. If the carrier element 2 is inserted against the contact surface 5, the carrier element 2 and in this case in particular the connecting element 7 can be brought under the extension by means of an elastic bending of the extension 3 and the carrier element 2 is seated in the holding frame 1 under prestress.
  • the holding frame is preferably 1 made of plastic or metal, such as die-cast zinc or aluminum, so that the extension 3 is elastically displaced and can be brought over the carrier element 2.
  • the projections 6 apply an additional clamping force and position the carrier element 2 very precisely in the holding frame 1. 5 Even if only one carrier element is provided in this and the following exemplary embodiments, it is also conceivable according to the invention to have a multi-part or several carrier elements and thus also to hold, position and hold several sensors in one holding frame. It is conceivable to connect one or more connecting elements for electrical contacting to the different carrier elements.
  • FIG. 11 A closed form of a holding frame 11 is again shown in FIG.
  • the holding frame 11 also has a contact surface 12, a spring element 15 13, which is designed as a spring rod 13 and a number of extensions 14, 15, 16, by means of which a carrier element can be fixed and positioned in the holding frame 11.
  • the spring rod 13 is pivotally received in a holder 17 and has a first end 18, by means of which a force can be exerted on the carrier element, and a second end 19, which can be suspended under a projection in the form of a nose 20.
  • the extensions 14, 15, 16 are integrally connected to the holding frame 11 and act in such a way that they exert a force on a carrier element and press it in the direction of a pane.
  • a support frame can be inserted under the extensions 15, 16, whereas a support frame can be snapped or clipped in under the extensions 14 arranged in mirror image.
  • FIG. 3 shows a holding frame 11 according to FIG. 2 with the carrier element 21 inserted.
  • the holding frame 11 is provided on its underside 22 with an adhesive film or an adhesive and glued to the windshield.
  • the carrier element 21 is placed under the extensions 15, 16 pushed and snapped under the extensions 14.
  • a force action on the carrier element 21 that can be metered very precisely can be set.
  • the spring rod 13 is pivoted in the holder 17 in the direction of the arrow P and the second end 19 under the nose 20, against the bias caused by the first end 18 is generated against the carrier element 21, hung under the nose 20.
  • the support element 21 is additionally subjected to a force, so that there is an optimal connection of the sensor (not shown) in the support element 21.
  • the holding frame 11 is also provided with struts 23 for stiffening the holding frame 11.
  • a shaped sheet 24 is shown in FIG.
  • the shaped plate 24 has a first flat region 25 and a second protruding region 26 and also mounting openings 27.
  • the shaped plate 24 is preferably made of steel and more preferably of spring steel, but in any case from an elastic, movable, high-quality material.
  • two angled tabs 28 are attached in the protruding area 26, two angled tabs 28 are attached.
  • a carrier element 29 can be brought under these tabs 28. A preload is applied to the carrier element by means of the tabs 28 and the carrier element 29 is simultaneously positioned.
  • FIG. 30 An open form of the holding frame 30 is shown in FIG.
  • the molded sheet 24 has been extrusion-coated with plastic, so that the holding frame 30 is formed as a composite component from the molded sheet 24 and the plastic jacket.
  • Another component such as a cover cap, can now be mounted in the mounting openings 27.
  • the mounting bracket 27 in the protruding area 26 is preferably used to raise the area 26 when mounting the carrier element 29 with the integrated sensor.
  • FIG. 7 shows the holding frame 30 in which a carrier element 29 is inserted.
  • the carrier element 29 is placed against the contact surface 31 and pushed under the protruding region 26, namely until the carrier element 29 is clamped under the projection 32 and fixed and positioned by means of the tabs 28.
