Definitions

  • the present invention describes a door handle of a vehicle and a Transponder system
  • the transceivers contain antenna coils, in particular double antenna coils could be.
  • Double antenna coils also as twin loop antennas known, are used to generate a magnetic field that the transponder of the key excited.
  • the two coils are arranged and controlled so that they generate an elliptical polarized field, which is a transponder that is in different directions can be held, can excite.
  • the reach of the Field is usually about one meter.
  • the two antennas will be usually housed in a transceiver housing, which either in one of the bumpers of the vehicle or in an exterior mirror. For However, vehicle manufacturers have found these two locations to be inconvenient proven. Bumpers and exterior mirrors are more likely to be damaged than any other parts.
  • the present invention describes a door handle for a vehicle with two Antenna coils of a transponder system for the vehicle.
  • the antennas can be used to create a magnetic field to excite a Generate a key transponder.
  • the magnetic field is preferably an elliptically polarized field.
  • the one antenna coil is preferably an air coil with a flat winding
  • the other antenna has a core made of magnetically conductive material, the core preferably consists of ferrite.
  • This ferrite core preferably consists of two Ferrite rods.
  • the present invention also describes a transponder system for a Vehicle that contains a transceiver for a double antenna coil, with two Antennas in a door handle of the vehicle.
  • a door handle 2 as shown in Figures 1 to 3, has a first end 4 with a Bearing 6 around which the handle 2 can pivot when it is on the vehicle is appropriate.
  • a second end 8 of the handle 2 contains a stop 10 which normally abuts the vehicle door when the handle 2 is not pivoted.
  • a gripping profile 12 is between the two ends 4 and 8 , so is designed so that a person can take it comfortably to open the handle 2 Swivel vehicle door.
  • the gripping profile section 12 is hollowed out or reset so that a cavity 14 is formed along the length of the gripping profile 12.
  • the cavity 14 is used to hold parts of a transponder system transceiver to accommodate the vehicle.
  • the transponder system is part of one passive vehicle access system of the vehicle.
  • the components are in the Cavity 14 housed sealed, a cap for the section of the Gripping profile 12 is not shown in the figures.
  • the components that are accommodated in the grip profile section 12 include other two antennas 20 and 22 for the transceiver.
  • the first antenna 20 is an air coil with a flat multiple turn 24, which in the cavity 14 on the Bottom surface 26 is attached or printed.
  • the coil 24 can, for example, on Foil or printed on a circuit board.
  • the second antenna 22 consists of a Multiple wire winding 30, which over two ferrite rods 32, as shown in Figure 9, are wrapped.
  • the wire coil 30 is connected to the output of the amplifier stage 33 Transceiver 34, as shown in Figure 4 connected.
  • the second antenna 22 is therefore used for the first antenna 20 to excite, which trimmed with the help of the trimming capacitor 28 to resonance is, so that the magnetic coupling or the inductance between the two antennas 20 and 22 is amplified.
  • To an elliptically polarized magnetic field to excite the transponder Transponder systems must generate the magnetic fields generated by the two Antennas 20 and 22 are generated to be substantially perpendicular to each other, with a 90 ° phase shift between the currents through the antenna coils 30 and must pass 24.
  • the physical relationship between the two coils 30 and 24 ensures that their magnetic fields are substantially perpendicular to each other are and the phase shift of 90 ° is due to the magnetic coupling or the inductance of the two antennas 20 and 22 and the resonance circuit of the first Antenna 20 generated.
  • the range of the magnetic field that the two antennas Generate 20 and 22 is between one and two meters. The magnetic field rotates synchronously with the period of the antenna currents.
  • the second antenna can be significantly smaller without that the generated magnetic flux density would be lower, making the right angle magnetic fields within the limited space in the Gripping profile section 12 of the door handle 2 can be generated.
  • the losses, caused by the magnetic coupling between antennas 20 and 22, can be reduced by controlling the antennas separately and no longer has magnetic coupling between the antennas.
  • a realization of it is the door handle 40, as shown in Figures 5 to 7.
  • the door handle 40 is the same as the handle 12 except that the second antenna 22 is right in the center of the first Antenna 42 is placed over the same to ensure that only a minimal There is coupling between the magnetic fields of the two antennas 22 and 42.
  • the first antenna 42 also differs in that it does not have a matching capacitor 28 contains more and that by a second output stage of a double antenna circuit 44 of the transceiver 46 is controlled, as shown in FIG.
  • the arrangement of the Antennas 22 and 42 are still such that those generated by the antennas Fields are essentially perpendicular to each other.
  • the two generate Output stages of the double antenna circuit 44 currents that are shifted by 90 ° in phase are.
  • door handles 2 and 4 include only the two Antennas of the transceiver 34 and 46, but the handles can also be constructed in this way be that they additionally electronic components of the transceiver 34 and 46 or can even contain all components of the broadcast receiver, as the remaining ones Components only take up a very small space compared to the antennas to take.
  • a person who tries to get into a vehicle usually approaches one Door handle, especially the handle of the driver's door, and for this reason, is suitable Door handle especially for the accommodation of the double antenna coils.
  • the door handle is also a much more robust component than an outside mirror or the bumper.
