Definitions

  • the invention relates to a cover for a radar sensor for motor vehicles, which has a wall with a three-dimensional relief structure.
  • Radar sensors are used in motor vehicles, for example for locating vehicles ahead, so that an automatic distance control is made possible. It is desirable to integrate the radar sensor and its cover into the radiator grille of the vehicle and, for example, to place it centrally in the upper region of the radiator grille so that it has a good field of vision and is largely protected against damage by stone chipping or the like. It makes sense that the relief structure of the cover reproduces the company symbol of the motor vehicle manufacturer.
  • the cover then has a variety of technical requirements to meet. It has to be radar-transparent and should disturb the transmission of the radar waves as little as possible and also cause as few disturbing reflections as possible.
  • the company symbol of the motor vehicle manufacturer has in most cases high-gloss surface parts and should therefore be effectively protected against environmental influences, so that this surface is not dull and unsightly.
  • the outer surface of the radar sensor should be as resistant as possible and especially scratch-resistant.
  • the object of the invention is to provide a cover with three-dimensional relief structure for radar sensors, which can be produced inexpensively and yet is of high optical, radar optical and mechanical quality.
  • At least one layer of the wall with the relief structure consists of deep-drawn glass.
  • this glass is formed by deep drawing so that it forms the three-dimensional relief structure of the cover.
  • the glass composition can be chosen so that a high transparency for radar waves is achieved, whose frequency is typically in the order of about 77 GHz.
  • the use of the formed glass as the base substrate of the cover enables a high mechanical strength and resistance, as well as a high optical quality and at the same time a low-cost production. Since fewer process steps are required than with conventional methods, numerous sources of error are eliminated, so that the rejects and thus the component costs are minimized.
  • the appearance of the cover can be influenced.
  • the printed or metallized surfaces are preferably on the radar sensor facing back of the cover so that they are protected against environmental influences.
  • a plastic layer can be attached, which forms a stable and distortion-free composite component together with the glass layer. The injection molding or injection-compression molding process makes it possible to achieve a good areal closure between the glass substrate and the plastic compound, so that no air inclusions are produced at which the radar waves would be reflected.
  • the plastic compound can be shaped in such a way that it forms mounting elements for fastening the cover or the entire radar sensor to the radiator grille or other body parts of the motor vehicle.
  • a transparent sealing compound or plastic sealing can be provided which compensates for the unevenness of the relief structure, so as to obtain a smooth surface, which can then obtain a scratch-resistant coating, for example with a thermosetting paint.
  • the recesses of the relief structure on the front can also be filled by a continuous transparent thermosetting resin layer.
  • FIG. 1 shows a schematic section through a device for deep drawing a transparent glass sheet.
  • FIG. 2 shows the device according to FIG. 1 at the end of a deep-drawing step
  • FIG. 3 shows an enlarged section through part of the deep-drawn glass sheet in the tool according to FIG. 2;
  • Fig. 4 shows a section, analogous to FIG. 3, through the glass to another
  • FIG. 5 shows a schematic section through a device for injection-compression molding of a plastic layer on the rear side of the glass pane
  • Fig. 6 is a section through a device for attaching a
  • FIG. 8 is a front view of the cover of FIG .. 7
  • FIG. 1 Starting material for the production of a cover for a motor vehicle radar sensor is shown in FIG. 1, a flexible glass 10, which is withdrawn as an endless belt from a coil 12 and passes between an upper tool 14 and a lower tool 16 of a punching and deep drawing device 18.
  • the Upperworks The tool 14 has an encircling punching blade 20 with which an example of a circular blank is punched out of the band 10. The scrap is then rewound onto a coil 22 on the other side of the device 18.
  • the upper tool 14 has an arrangement of projections 24 on the underside, while the lower tool 16 has a complementary arrangement of recesses 26.
  • a blank 28 is punched out and thereby deep-drawn by the projections 24 and depressions 26 and reshaped so that it receives a three-dimensional relief structure 30.
  • the upper and lower tools 14, 16 are interchangeably held in a machine bed 34 of the device 18, so that covers with different relief structures can be produced, for example, reproduce the company badge of the respective motor vehicle manufacturer.
  • the surfaces of the upper tool 14 and the lower tool 16 facing the blank have coatings 36 of PTFE (Teflon). This facilitates the deep-drawing process.
  • the edges of the recesses 26 in the lower tool 16 are rounded, so that on the side of the blank, which later forms the outside of the cover, no unsightly markings.
  • the deep-drawn blank 28 is ejected or, if appropriate, transferred together with the lower tool 16 serving as a workpiece carrier to a printing station (not shown), where the raised parts of the relief structure 32 on the rear side of the later cover (the upper side facing the radar sensor) in Figs. 2 and 3) are printed with a colored lacquer, for example in the pad printing process.
  • a part of the varnish layer 38 formed in this way can be seen in FIG.
  • an opaque metallization layer 40 is then continuously applied to the entire back side (upper side) of the blank 28, which for example has a thickness of at least 50 nm and, for reasons of radar transparency, preferably consists of indium, gold or tin.
  • the printed and metallized blank 28 is transferred into an injection molding machine 42 with an embossing function, which is shown in section in FIG. 5.
  • the blank 28 can remain on the lower tool 16 of the punching and deep-drawing device serving as a workpiece carrier even in this step, that the injection molding device is then implemented and suitably positioned in a bed 46 of the injection molding machine with ejectors 44.
  • the bed 46 and a peripheral wall 48 and an embossing die 50 of the injection molding machine are traversed by heating channels 52 so that the injection molding machine including the blank 28 can be heated to a temperature of, for example, 120 to 140 ° C.
  • a mold cavity 54 is limited above the blank 28, in which via a sprue 56, a preheated plastic melt is injected, preferably at a pressure of less than 500 MPa.
  • the plastic may be, for example, a polycarbonate or a thermosetting resin material.
  • the embossing punch 50 is separated by an embossing gap 58 from the peripheral wall of the injection molding machine 42 and moves during the injection molding deeper into the mold cavity, so that the plastic melt is pressed firmly against the metallization of the blank 28. In this way, full-surface adhesion of the plastic to the metallization layer of the blank without air inclusions is achieved. The adhesion can be further improved by subjecting the metallization layer 40 to a plasma treatment prior to the injection molding process.
  • the mold cavity 54 is designed so that the peripheral edge of the blank is embedded in the plastic mass and thus the injection-molded plastic layer 60 (FIGS. 6 and 7) forms at its edge radially projecting brackets 62 with 25 mounting holes 64 which provide an attachment of the Cover on a grille or other body part of the vehicle allow (see also Fig. 8).
  • the lower tool 16 is ejected and returned to the punching and deep drawing device 18 for further use.
  • the cover 66 may be used in the state by leaving the injection molding machine 42.
  • a filling layer on the front side (underside) of the blank can be injection-molded, comparable to the filling layer 68 shown in FIGS. 6 and 7.
  • This filling layer fills at least the depressions of the relief structure, but preferably forms on the outside of the cover a continuous planar surface and is made of transparent plastic, such as transparent polycarbonate, so that the relief structure remains visible.
  • the flat surface of the filling layer can be coated with a scratch-resistant transparent lacquer.
  • FIG. 6 illustrates another embodiment in which the filling layer 68 is produced in a casting machine 70 with a simple casting tool 72 in the reaction injection molding (RIM) process.
  • RIM reaction injection molding
  • low-viscosity casting compounds e.g. be used on polyurethane or acrylate basis.
  • a mixing head 74 e.g. an isocyanate and a polyol are combined and injected into the heated tool at a pressure of less than 500 MPa.
  • chemical reaction forms in the mold cavity, a crosslinked resin, which is very temperature and dimensionally stable and forms a scratch-resistant flat surface that does not need to be painted.
  • the finished cover 66 obtained in this way is shown in section in FIG. 7 and in a front view in FIG. 8.
