Definitions

  • the invention relates to a composite pane comprising an electrically controllable attachment embedded in a recess, a method for producing the composite pane, and the use of the composite pane as a motor vehicle pane.
  • Modern glazing systems are equipped with a variety of electrically controllable attachments, such as sensors, detectors, receiving or lighting units.
  • electrically controllable attachments such as sensors, detectors, receiving or lighting units.
  • camera systems, rain sensors, antennas and decorative or functional lighting elements should be mentioned, especially in the automotive sector.
  • the number of electrically controllable attachments in the motor vehicle is also increasing. These must be protected because of their sensitivity to the weather and are usually placed behind the windshield of the motor vehicle in the passenger compartment.
  • EP 2 462 007 B1 describes a composite pane having an optically transparent sensor field and a sensor mounted in the region of the sensor field.
  • the sensor is located within an enclosure which projects into the passenger compartment of a motor vehicle. This encapsulation is visible in the passenger compartment as a survey on the disc and is perceived by the driver as possibly disturbing and restricting the field of view.
  • the photodiode is laminated in a thermoplastic intermediate layer which connects the outer pane and the inner pane of the composite pane.
  • thermoplastic intermediate layer which connects the outer pane and the inner pane of the composite pane.
  • the problem of a space-saving and visually inconspicuous integration of electrical components in composite panes affects not only sensors, but also functional or decorative lighting elements.
  • material-removing methods for example laser structuring
  • the light rays are thereby coupled in via the edge of the glass pane, while in the abrasive treated areas of the pane a light extraction takes place.
  • the targeted light extraction causes a glow of these areas in the form of the introduced symbols or characters, as shown for example in DE 20 2006 006 051 U1 based on a vehicle rear window with illuminated warning symbol.
  • a light coupling over the edge of the glazing greatly restricts the possibilities for positioning the light sources, since their arrangement can take place exclusively along the corresponding glazing edge.
  • WO 2004 080712 A1 discloses composite disks in which one of the individual disks of the composite disk has an opening into which a lighting means is inserted.
  • the breakthrough is created by mechanical methods such as drilling or milling. Such methods provide a sufficient product quality for planar disks with the usual in building glass pane thicknesses. Especially with more complex geometries of a breakthrough, with curved disks and with smaller pane thicknesses, such mechanical methods lead to only insufficient results.
  • WO 2004 106056 A1 discloses a composite pane in whose intermediate layer lighting means, for example in the form of strip-shaped LED elements, are used. In one of the discs blind holes may be provided for receiving the bulbs.
  • the applications described in WO 2004 106056 A1 are located in the field of planar decorative glazing.
  • DE 2014642 is concerned with improved antenna conductors in automotive glazings, with the aim of reducing the interference. It was found that a minimum distance of 5 cm between the electrical connection point of the antenna conductor and the metallic body opening, in which an automobile window is used, proves to be advantageous.
  • a bore with a corresponding minimum distance to the window surround is provided in the inner pane of a laminated glass pane. In this hole, an electrical connection element is provided and the electrical connection led to the outside.
  • WO 2007 009973 A1 and WO 2007 009974 A1 describe capacitive rain sensors for use in vehicle windshields, which are incorporated in the intermediate layer of a composite pane.
  • the object of the present invention is to provide a composite pane with electrically switchable attachment, wherein the attachment is space-saving and visually inconspicuous integrated into the composite pane. Furthermore, it is an object of the invention to provide a method for producing such a composite disk.
  • the composite pane according to the invention with at least one integrated electrical attachment comprises at least one inner pane and one outer pane, which are laminated together via a thermoplastic intermediate layer.
  • the composite pane is a vehicle composite pane with three-dimensional bending.
  • the inner pane and the outer pane each have an inner side and an outer side which run essentially parallel to one another.
  • the thermoplastic intermediate layer connects the inside of the inner pane and the inside of the outer pane.
  • the inner pane and / or the outer pane has at least one recess in which the electrical attachment is embedded.
  • the electrical attachment is located completely within the composite disc and protrudes beyond the composite disc in any dimension. That is, the electrical attachment is located completely between the outside of the inner pane and the outer side of the outer pane.
  • the recess is introduced by laser process in the inner pane and / or outer pane.
  • the electrical attachment is thus space-saving and visually unobtrusive integrated into the composite pane.
  • a patch on the surface of the composite disk encapsulation of the attachments is not required.
  • the various electrical attachments that are located in the field of vision of a motor vehicle glazing, visually appealing.
  • Modern vehicle composite discs are bent three-dimensionally, whereby a development towards ever stronger bends can be observed in the sense of a striking, visually appealing design.
  • the composite pane according to the invention is a vehicle composite pane with a cutout produced in the laser process.
  • Such a recess has a correspondingly high precision and manufacturing tolerance, so that This is also suitable in three-dimensionally curved discs is a fixture of a fixed size to fit accurately.
  • a recess produced by means of a laser process can be distinguished in its surface structure and precision from an opening produced by means of mechanical methods.
  • the recess has, at least in sections, an angular contour.
  • a contour of the recess the shape of the circumference of the recess in plan view is referred to one of the disc surfaces in this sense.
  • the term is to be understood in the context of the invention as "non-circular".
  • a polygonal contour with rounded corners also represents an angular contour.
  • a polygonal contour or a contour with a sectionally angular shape is advantageous with regard to a secure fixing of the attachment. In a circular recess twisting of the attachment is possible. An angular recess prevents this.
  • a circular recess may in some cases appear more visually appealing, for example in the case of a light source as an interior lighting or reading lamp. In these cases, however, a rotation of the attachment is still to be avoided when touching a lying on the outside of the disc surface.
  • the circular recess is extended by one or more lateral notches, which connect directly to this. Overall, this results in a square contour of the recess.
  • other advantages of a non-circular recess are also conceivable.
  • the recess with respect to its contour can be optimally adapted to the shape of the attachment. Further, adjacent to a main opening recesses can be used for attachment or for receiving electrical connection elements, which also results in a polygonal contour of the recess.
  • the recess is embodied in at least one partial area as a passage opening and in at least one further partial area as a non-continuous partial recess.
  • the depth of the recess corresponds to the pane thickness of the mecanical- or Outer pane into which the recess is made.
  • the depth of the recess is less than the thickness of the disc, in which the recess is introduced. This is advantageous because in this way a portion of the attachment can be provided exposed on one of the disc surfaces, while another portion is enclosed by the disc.
  • the portion of the recess which is designed as a non-continuous partial recess, thus serves for example to receive over the attachment protruding elements such as cables, connection elements or fasteners.
  • fastening elements for the attachment or attachment elements of the attachment itself can be provided in the region of the partial recess.
  • fastening elements are provided in the region of the partially non-continuous recess, via which an attachment, which is used in the region of the passage opening, is reversibly fixed. On the exposed surface of the through hole, the attachment can thus be replaced.
  • the fasteners are, for example, clip profiles.
  • the fasteners may be integrally attached to the attachment itself, to a cover of the attachment or as a separate elements.
  • the inner edge of the recess is chamfered, i. it forms with the disc surfaces of the disc, in which the recess is introduced, a deviating from 90 ° angle.
  • This is advantageous to allow a reversible replacement of attachments, for example via a flexible rubber ring which is inserted in the tapered portion and is removed for replacement of the attachment.
  • the beveled area can also be used to enlarge the gap between attachment and disc, which serves to accommodate adhesives for bonding the attachment, and to ensure secure bonding.
  • the angle a between the inner edge of the recess and one of the adjacent disk surfaces is preferably 20 ° to 80 °, more preferably from 30 ° to 70 °, in particular from 40 to 60 °. This achieved good results.
  • An embodiment of the invention comprises a composite pane with a through hole in the inner pane, wherein the inner edge of the through hole is chamfered at least in some areas. The inner edge assumes an angle within said areas to the outside of the inner pane.
  • This embodiment is advantageous for receiving fastening elements, such as clip profiles, with which the attachment can be removed reversibly.
  • the at least one electrical attachment is located entirely within a recess of the inner pane or outer pane. This is advantageous, since therefore only one recess per attachment must be generated. There may be several recesses, each with at least one attachment.
  • the electrical attachment can also protrude in parts into the thermoplastic intermediate layer. This is advantageous if an attachment is introduced on the inside of the inner pane or the outer pane and the depth of the attachment is slightly greater than the depth of the recess.
  • congruent recesses in the inner pane and the outer pane are mounted, wherein the electrical attachment is inserted in these two congruent recesses and protrudes into both recesses.
  • the attachment is fully integrated within the composite disc and does not protrude beyond it. This embodiment is particularly advantageous if the dimensions of the fixture to be integrated compared to the thickness of the inner pane or outer pane are quite large. In this case, two congruent recesses are made to accommodate larger attachments.
  • the attachment protrudes through the thermoplastic intermediate layer.
  • the inner side of the inner pane of the laminated glass according to the invention is the surface of the inner pane directed in the direction of the thermoplastic intermediate layer, while the outer side of the inner pane is oriented in the installed position relative to the vehicle interior.
  • the inner side of the outer pane is likewise aligned with the thermoplastic intermediate layer, whereas the outer side of the outer pane faces the outer environment.
  • the inner pane and the outer pane contain glass and / or transparent plastics such as polycarbonate or polymethylmethacrylate.
  • the composite pane according to the invention can also have a plurality of electrical add-on parts which are introduced within recesses of the inner pane and / or the outer pane.
  • the recess in one of the discs of the composite disc can be designed both as a through hole, as well as a non-continuous recess of the disc.
  • Through hole refers to a hole that extends from the inside of a disc to the outside of the same disc and thus completely penetrates the disc.
  • a discontinuous recess does not completely penetrate the disk and constitutes only an opening extending from a disk surface (inside or outside) which does not protrude to the opposite surface of the same disk.
  • the recess is preferably a borehole. This can have any desired contour, preferably a circular, elliptical, rectangular or trapezoidal contour.
  • a through-hole is mainly used in the inner pane for use, since in this case, the outer pane of the composite pane provides the necessary protection against the weather.
  • An embodiment of the recess as a passage opening in the outer pane is however also conceivable, in particular if the composite pane is integrated in a pane arrangement of a plurality of panes and the required protection against environmental influences is ensured by another pane of the pane arrangement.
  • the recess is a passage opening in the inner pane.
  • the passage opening extends from the outside of the inner pane to the inner side of the inner pane.
  • the depth of the recess is less than the thickness of the inner pane or outer pane in which the recess is made. It is thus only a partial recess in which the material of the disc is not penetrated in its full depth of the recess.
  • the recess thus extends from a first disk surface (inner surface or outer surface) into the interior of the disk, wherein disk material remains between the bottom surface of the recess and the second disk surface opposite the recess.
  • This second preferred embodiment is particularly advantageous to complete the recess on a disc surface against the environment.
  • the recess is arranged, for example, so that the disc material remaining between the bottom of the recess and the opposite disc surface covers the recess toward the environment or to the thermoplastic intermediate layer.
  • a recess in the form of a passage opening connects the outside of the disc with the inside of the disc. This carries the risk of moisture entering from the outside of the pane through the passage opening into the interior of the laminate of the composite pane.
  • corrosion-prone coatings on the inside of the disc corrosion damage in the form of rust marks immediately visually disturbing the eye. Such corrosion damage can be completely avoided using the second embodiment of the invention.
  • the electrical attachment is used in the manufacturing process before lamination of the composite pane into the recess. Subsequent processing of the laminated disc is therefore no longer necessary. The two outer sides of the disc remain completely intact, which is not only visually appealing, but also offers the greatest possible protection of the attachment and the laminate from moisture and environmental influences.
  • the depth of the recess it is also possible to make recesses with partial areas designed as through-holes and partial areas designed as non-continuous partial recesses.
  • the depth of the recess is at least partially smaller than the thickness of the outer pane or inner pane into which the recess is made. Areas of lesser depth may be provided in steps or provided as bevelled areas.
  • an inner pane or outer pane with through-hole with an inner pane or outer pane with a partial, non-continuous, recess is also possible.
  • An application example of this would be a composite disk comprising an inner disk with through-opening and an outer disk with a non-continuous recess on the inner side, wherein the recess of the outer disk is positioned congruent with the through-opening of the inner disk.
  • the integration of electrical attachments with increased space requirements is possible.
  • pane thicknesses of an automotive glazing are usually in the range of 0.3 mm to 2.5 mm for the inner pane and in the range of 0.8 mm to 2.5 mm for the outer pane.
