Definitions

  • the invention concerns a cover for vehicular antennas particularly suitable to be used for the protection of elements transmitting and/or receiving signals through the air and belonging to equipment installed on motor vehicles, e.g. telephones, car radios, satellite navigation systems.
  • materials with particular physical-mechanical features are used, mainly nylon, which make it possible to obtain strong covers and at the same time, in the moulding phase, to satisfy the aesthetic requirements imposed by the manufacturer's design.
  • terminal elements that make up the antennas for transmitting and receiving signals through the air, in particular telephone signals with GSM or AMPS technology, they comprise mainly longitudinal metallic elements that constitute monopoles in tune with the signal transmitting/receiving frequency and are fixed to a base for installation on the vehicle's bodywork.
  • regulations which set the maximum overall length admissible for the parts protruding from the car's bodywork, in particular for antennas.
  • the covers for vehicular antennas are carried out with specific geometric and physical-mechanical characteristics.
  • the covers produced according to a first known technique feature the coupling of two distinct elements: the first one of these elements, essentially in the shape of a shell, is suited to be coupled to the connection base on the motor vehicle's bodywork, while the second one comprises a hood wrapped around the monopole and fitted into the first element.
  • the structure of the cover obtained through the union of two separate elements has the flexibility necessary to comply with the regulation mentioned above.
  • antenna covers made in one single piece, for example through moulding have been designed, said covers having on their outer surface, and at predetermined heights, annular grooves suitable for creating areas with reduced thickness that make the protruding part flexible in case of impact.
  • US 6,275,194 discloses a cover for vehicular antennas comprising a breaking point located underneath a threaded head and serves as the breakable fastening element in case of emergency.
  • EP 0989629 discloses a cover and a metal base for a vehicular antenna which is mounted on the roof or a vehicle.
  • a first objective of the invention is to produce a cover for vehicular antennas with physical-mechanical characteristics in compliance with the regulations in force and with external surface without discontinuities.
  • Another objective of the invention is to obtain a cover for antennas whose production requires simpler operations compared to the equivalent covers already known.
  • the notch is annular with an elliptical profile.
  • the cover has a lowered area that gives the cover itself the flexibility required by the above mentioned safety standards.
  • the monopole M is electrically connected to signal receiving and/or transmitting means installed on the vehicle, not shown in the figure to simplify the representation and because they are of the known type.
  • the monopole M represented here substantially comprises an antenna that receives and/or transmits telephone signals, e.g. signals used for GSM or AMPS communication.
  • the cover for antennas 1 object of the invention substantially comprises a lower part 2 covering the base B on which it rests and an upper part 3 covering the monopole M when the antenna is assembled.
  • the lower part 2 and the upper part 3 make up a single body inside which, as shown in figures 4 and 5, a notch 4 is obtained to reduce the thickness of the material of which the cover is made in correspondence with the connection area between the lower part 2 and the upper part 3.
  • Said notch 4 as shown in the view from below of Figure 6, is annular in shape, with an elliptical profile and reflects the shape of the upper part 3 of the cover 1.
  • the cross section of the notch 4 has a substantially right shape and comprises two concurrent walls 4a, 4b that cut the cover 1 in the connection area between the lower part 2 and the upper part 3.
  • the notch 4 is obtained during the moulding of the cover 1, which is preferably made of nylon PA6, commercially known as WELLAMID.
  • the profile of the notch 4 may be different, according to the design, the moulding techniques and the material used.
  • the annular notch 4 obtained in this way independently of its shape, makes it possible to obtain a reduced resistance area compared to the other parts of the cover 1, so that in case of impact the upper part 3 will yield and even come off the lower part 2, according to the provisions of the regulations in force.
  • the upper part 3 as can be seen in detail in Figure 3, is substantially fin-shaped and adapts to the shape of the monopole, which makes it possible to obtain better aerodynamic penetration coefficients for the antenna.
  • holes 5 are provided, which are suited to receive fixing screws V for fastening to the base B during the assembly of the antenna.
  • a lower annular circle 6 is also obtained on the lower part 2 and is suited to house the sealing gasket G associated to the base B that, upon completion of the assembly, guarantees the protection of the antenna from seepage of water.
  • the cover 1 object of the invention is applied to an antenna in which, in addition to the monopole M for transmitting and receiving telephone signals, means S are provided for receiving satellite signals, e.g. the GPS type, said means being substantially flat in shape and housed in a compartment in the base B.
  • Said variants may for example involve a different shape of the lower and upper parts, as well as a different shape of the notch, or even a different type of connection to the support base.
