Definitions

  • the invention relates to a support plate for a mirror glass, with a heater.
  • such a carrier plate which is formed by carbon fibers, which are connected to each other in a conductive manner via a binder.
  • An adhesive layer is used to apply a mirror glass to the carrier plate.
  • the mirror glass has a reflective layer on the rear side facing the carrier plate.
  • the reflection layer is then attached to the outside of the mirror glass, with increased risk of damage to the reflection layer.
  • the conductive paste is to be baked at a temperature of about 670 ° in the known method, resulting in problems in compliance with the bending accuracy can result in spherical and aspherical mirror glasses.
  • DE 42 23 590 A1 shows a mirror in which on the front of the mirror glass a transparent heating device is attached as an ITO layer, which is covered by a protective layer, for example, by sputtering or in Plasma order is attached.
  • a transparent heating device is attached as an ITO layer, which is covered by a protective layer, for example, by sputtering or in Plasma order is attached.
  • the ITO layer is very sensitive to damage, which can lead to local overheating (hot spots).
  • FR 2 618 396 A1 describes a carrier foil for a mirror glass, with a heating device applied by screen printing. On the front side of the heating device facing the mirror glass, a secure connection between the mirror glass and the carrier film is established via a double-sided adhesive tape. In addition, this will seal the heater.
  • the object of the invention is to provide a support plate for a mirror glass of a mirror, in particular an outside mirror of a motor vehicle, which can be produced with little effort and allows the production of the mirror in a cost effective manner.
  • Claim 8 describes a mirror with a carrier plate according to the invention.
  • the core idea of the invention according to claim 1 is to apply the heating device to a carrier plate directly by a thermal spraying method according to DIN EN 657.
  • thermal spraying process covers all processes in which spray additives are supplied inside or outside a spray gun and heated to the plastic or molten state and then thrown onto the prepared surface, the surface not being melted.
  • the particles which by means of compressed air, heating gas, cold gas, light arc, plasma, etc. are thrown onto the surface to be coated with high kinetic energy, mechanically cling to the surface upon impact.
  • the particles which are subsequently fed further onto the surface in turn become entangled in the previously applied particle layer. The result is a layer that is in intimate connection with the carrier plate.
  • the resistance material is in this case in wire, powder or granular form in a specially designed "burner" (in the manner of a spray gun) fed, the material melted and then the molten particles by one of the energy sources mentioned in Table 1 of DIN EN 657 high kinetic energy are thrown onto the surface to be coated.
  • the heating device according to the invention is advantageously designed in one piece with the carrier plate. This reduces the assembly effort. Also, an increase in the reliability of the heater is achieved. In contrast to the known sticking of the heating foil on the support plate, the production can be automated by a spray robot. Also, weight advantages result from the one-piece design, compared to the separate design of the heater as a heating foil or otherwise. The installation costs can be reduced by eliminating the adhesive tape.
  • ferrous metals non-ferrous metals, conductive plastics, cermets (sintered ceramic metals), etc. can be processed. Also, special alloys with selected specific resistive resistance can be processed.
  • the order of the resistance material can be carried out continuously along the desired course of the conductor track.
  • a mask is used to accelerate the application of material covering those areas of the support plate to which no resistance material is to be applied, so that the order of the resistance material can be made flat.
  • the free spaces of the mask in this case correspond to the course of the conductor track.
  • the mask is preferably coated with an antiblocking agent. The hereby achieved clean detachment of the mask from the support plate ensures sharpened boundaries of the conductor. In addition, the mask can be easily cleaned and thus used several times.
  • the carrier plate is produced as an injection-molded component from a thermoplastic or thermosetting plastic.
  • two or more contact pins are inserted into the injection mold, which are encapsulated in a row in one operation with the production of the carrier plate and thus manufactured in one piece with the carrier plate. By overmolding the contacts, they are protected against corrosion and penetration of spray water.
  • the resistance material of the conductor track on the support plate and the periphery of the heater can be sprayed by a thermal spray process according to DIN EN 657 on the support plate.
  • This may be, for example, the power supply for the conductor track act, which is formed by a highly conductive material.
  • insulating materials can also be applied to the carrier plate using a thermal spraying method according to DIN EN 657.
  • the electrical insulation of the heater relative to the reflective layer of the mirror glass by an adhesive or an insulating varnish is a double function, namely on the one hand, the electrical insulation and on the other hand, the connection of the mirror glass with the support plate.
  • the adhesive or the insulating varnish the sensitive to mechanical stresses and environmental influences reflection layer of the mirror glass is protected.
  • mirror glass is used in connection with the present invention not only for mineral glass, but also for all conceivable other transparent substrates, for example of thermoplastic or thermosetting materials.
  • FIG. 1 shows a carrier plate according to the invention in plan view
  • Fig. 2 is a sectional view taken along the section line A-A of Fig. 1 and
  • a support plate 1 for a mirror not shown in detail, in particular an exterior mirror for a motor vehicle, has at the a mirror, not shown.
  • the ends 3 of the conductor 2 are led out on one side of the carrier plate 1 and connected to angled contacts 4.
  • the carrier plate 1 is made of a plastic material and is produced by injection molding. Webs 5 on the back of the support plate increase the mechanical rigidity of the support plate 1.
  • the contacts 4 are inserted in the production of the support plate 1 in the injection mold and are sprayed in injection molding in a single operation with the production of the support plate 1 of plastic material.
  • the conductor track 2 is sprayed meandering in a plurality of loops on the front side of the carrier plate 1.
  • the available area of the carrier plate 1 plays a role in the selection of the resistance material.
  • the following table gives a selection of possible resistance materials, their specific electrical resistance as well as the required total length of the conductor track.
  • the starting point here is, for example, a cross-sectional area of the conductor track of 0.2 mm 2 and a desired resistance of 6 ohms, in order to achieve a heating current of 2 amperes and thus an electrical power of 24 watts for a vehicle electrical system voltage of 12 volts.
  • two or more separate heating circuits may be provided with electrically separate interconnects 2 and contacts 4.
  • the carrier plate 1 As a material for the carrier plate 1 are all types of plastics, fabrics and nonwovens made of carbon or glass fibers, but also paper or textile materials.
