Definitions

  • the invention relates to an antenna for a vehicle for mounting on a vehicle surface, in particular a vehicle roof, according to the features of the preamble of patent claim 1.
  • Such an antenna for a vehicle is known from DE 295 00 961 U1.
  • This antenna has a base plate (base body) made of metal, on which the necessary antenna elements (such as a stripline antenna) are arranged.
  • the necessary antenna elements such as a stripline antenna
  • the entire antenna is fixed on this vehicle surface via a threaded bolt on the base plate, which engages in an opening in the vehicle surface.
  • the base plate of the antenna of DE 295 00 961 U1 is fitted into a receptacle on the underside of the antenna housing.
  • Four holes are provided in the corners of the base plate for fastening the antenna housing to the base plate. Through these four holes, screws are inserted, which engage in corresponding threaded holes in the antenna housing.
  • the antenna housing and base plate are detachably connected to one another, but no reliable sealing action is connected. This means that dirt particles and, above all, moisture can penetrate the antenna housing and thus impair the functioning of the antenna.
  • the assembly and the associated variety of parts is also disadvantageous, since the base plate is initially provided with the holes must and correspondingly the antenna housing must have the threaded inserts. Then four screws must be used to establish the connection between the base plate and the antenna housing. After that, measures must be taken that reliably fix the screws in the antenna housing so that they do not come loose due to vibrations during operation of the vehicle and the antenna housing is lost.
  • the invention is therefore based on the object of an antenna for a vehicle
  • the base body has at least one partial area made of plastic, the housing being non-detachably connected to the partial area after assembly of the front elements.
  • the permanent connection which can be, for example, an adhesive connection or a connection by means of ultrasonic welding, can be installed after the
  • Antenna elements are done automatically. Since in the area in which the antenna housing is to be connected to the base plate, the two parts consist of the same material or consist of two materials that can be easily connected to one another, this connection is quick and easy, but also inexpensive to produce. Once the non-detachable connection has been made, absolute tightness of the interior of the antenna housing is also associated with it, so that impairments to the function of the antenna are effectively avoided since no dirt particles or moisture can now penetrate into the interior.
  • the antenna housing in the area of the connection is adapted to the partial area made of plastic of the base plate.
  • the antenna housing can already be positioned and fixed on or on the base plate, as a result of which the inseparable connection can then be made in a particularly automated manner without further problems.
  • the partial area made of plastic is arranged all around on the edge of the partial area made of metal of the base plate. If the partial area made of plastic is arranged all around on the edge of the base plate, which can be carried out in particular by injection molding of plastic material), the largest possible area is available for mounting the antenna elements.
  • there is an optically acceptable appearance since the antenna housing is flush with the edge area of the base plate.
  • a schematically illustrated antenna 1 has a base body 2, the base body 2 having a partial region 2.1 made of metal, which is absolutely necessary for the functioning of the antenna 1.
  • the base body 2 also has at least one partial area 2.2 made of plastic, which in the exemplary embodiment is located all around on the edge of the partial area 2.1 made of metal. It is entirely conceivable here that, for example, the section 2.2 made of plastic also extends at least partially over the section 2.1 made of metal.
  • a plastic housing 3 is placed over the base body 2 and surrounds and protects the antenna element (possibly including electronic components, such as an amplifier), which are arranged on the base body 2.
  • the antenna elements vary depending on the intended use of the antenna 1 and are not shown in the figure for the sake of simplicity.
  • the areas of the housing 3 and the subarea 2.2 of the base plate 2 which are adjacent to one another are connected to one another in a non-detachable manner.
  • the contact areas of the housing 3 and the sub-area 2.2 can be adapted to one another, which, for. B. is shown in the form of a paragraph in the section 2.2 in the figure.
  • the sub-area 2.2 has a circumferential groove in which the lower edge of the housing 3 engages.
  • the non-detachable connection between the housing 3 and the sub-area 2.2 is marked V in the figure.
  • the antenna 1 is mounted on a vehicle surface 4.
  • This vehicle surface 4 has an opening 5 (body hole) into which a projection 6 (with a thread) engages, the projection 6 being part of the base body 2.
  • a hexagon nut 7 is screwed onto the projection 6, for example.
  • a seal 8 is also provided, which is designed in particular so that the opening 5 is reliably sealed to the outside against the ingress of dirt particles and ingress of moisture ,
