Definitions
- the invention relates to a method for producing vehicle parts from plastic, in which antenna elements are integrated, and to the components produced by this method.
- plastic components as a replacement for conventional metal parts has become particularly widespread in the automotive industry in recent years.
- Plastic components are an interesting alternative to metal parts, especially in terms of lightweight construction.
- they can be manufactured inexpensively, for example, by the injection molding process.
- a coating method which is particularly suitable for plastic components is specified, for example, in US Pat. No. 5,156,882.
- a layer system consisting of three layers is applied to the plastic carrier, which have UV-absorbing and scratch-resistant properties.
- WO 92/21161 proposes an antenna arrangement which is designed as a flat element and is applied to plastic components of a vehicle body.
- the antenna structure is manufactured separately and applied or integrated in an additional processing step on the body part.
- a disadvantage of this method is that the application of the antenna structure as an additional operation generates an increased effort for the adjustment of the structure; Furthermore, the protection against mechanical stresses is not optimal when the antenna structure is arranged on the surface of the component.
- the invention has for its object to integrate antenna elements easily and inexpensively in plastic components and to ensure maximum mechanical protection of the antenna elements mentioned.
- the antenna elements are introduced into the plastic structures as part of a painting process for plastic parts.
- the flat antenna elements are arranged between the paint layer and the component to be painted, the so-called plastic carrier.
- the monolithic view of the plastic part is a structural unit deviated and considered paint layer and plastic carrier as individual components of the plastic part; the space between these two components is advantageously used according to the invention.
- antenna elements are, for example, dipole, ring and slot antennas particularly suitable for mobile radio with the necessary electrical / electronic components such as.
- B. couplers, filters and distribution networks conceivable.
- a number of advantages are realized by applying the antenna elements between the lacquer layer and the plastic carrier.
- the arrangement of the antenna element on the surface of the plastic carrier makes the positioning of the element considerably easier by using the plastic surface as a reference surface; at the same time, the lacquer layer covering the antenna element offers optimum protection against external influences, thus offers a radome function and, as a superstrate, influences the electrical properties of the antenna. Furthermore, this method allows the integration of the surface finish and the antenna assembly in one work step. In addition, the space requirement of the antenna element is reduced by the integration into the space between the lacquer layer and the plastic carrier. Since the antenna elements can be produced from thin conductive foils, for example, there is no longer any impairment of the visual appearance of the vehicle; it is therefore no longer necessary to take the integration of the antennas into account when considering the design. The application of the antenna structure can be easily integrated into existing manufacturing processes and thus only causes a small additional financial outlay.
- the paint film is applied to the component to be painted during a shaping process.
- the shaping process can e.g. B. can be an injection molding, back-pressing or back-foaming process.
- injection molding liquid plastic is injected into a closed injection mold. The hot plastic melts the carrier material and the film forms a covalent bond with the back injection material.
- the antenna elements When integrating the antenna elements into the plastic components, it has proven particularly useful to integrate the introduction of the elements together with the painting process into the molding process. For example, when using a molding tool, it is advantageous to insert the antenna elements into the tool before the molding process. After the shaping process, the surface of the components can then be treated with the antenna elements already superficially integrated either with a conventional painting process or with a film painting process.
- the antenna elements When using a film coating process, it is also possible to apply the antenna elements to the coating film before the shaping process.
- the lacquer film is then introduced into the mold and then back-injected or back-foamed, for example by means of an injection molding or foaming process.
- the methods which have been tried and tested for the metallization of films can advantageously be used to apply the antenna elements to the lacquer film.
- direct metallization the paint film is first activated chemically; then a thin metal layer is deposited in a metal salt solution on the back of the paint film, which is subsequently galvanically reinforced to the thickness necessary for adequate mechanical stability and electrical conductivity.
- the metal layer can then be structured using known photolithographic processes.
- the plastic carriers can also be metallized using the methods mentioned.
- Different methods can advantageously be used for an alternative preparation of the antenna elements. For example, it is favorable to punch out the antenna elements as stamped parts from a metal foil and to glue them onto the lacquer foil or the plastic carrier in preparation. There is no need to use chemicals; the achievable accuracies easily meet the requirements for use as an antenna element.
- Commercially available copper adhesive tape with a total thickness of 65 ⁇ m 35 ⁇ m copper and 30 ⁇ m acrylic adhesive has proven particularly useful.
- antenna elements are arranged on substrates such.
- foil conductors or prepared circuit boards are good options for applying the antenna structures to the lacquer foil or the plastic carrier.
- the antenna elements can be applied to the paint film before the deep-drawing process .; alternatively, application to the paint film after the deep-drawing process is also conceivable.
- Another advantageous variant of the production of the plastic components consists in advantageously using the geometry of the molding tool used for positioning the antenna elements, for example by means of a robot.
- the antenna elements can be automatically aligned using optical methods, such as, for example, image recognition methods.
- the antenna element can be directly galvanically contacted.
- the passage of a waveguide through the plastic up to the cast-in antenna element is necessary. It is advisable to provide the component with a hole using the shaping method, which extends through to the inserted antenna element and then to contact the antenna element directly, for example by means of the inner conductor of a coaxial mounting socket.
- the conductor prefferably be passed through during the shaping process.
- the opening required for this can already be opened at
- a further possibility of coupling the antenna element is a so-called aperture coupling.
- the direct galvanic contacting of the antenna element is not necessary here; rather, a module is attached to the rear of the plastic component, which contains a feed network with a feed line and the electrical and electronic components necessary for coupling to the antenna element. This procedure eliminates the otherwise necessary through-plating through the plastic, thereby further simplifying the manufacturing process.
- the module with the feed network is separated from the antenna element by a ground plane.
- the energy transfer takes place through a gap in the ground surface via the magnetic coupling of the feed line to the antenna element.
- the coupling becomes maximum when the gap is placed under the center of the antenna element.
- the aperture coupling has a number of variable parameters. For example, the input resistance is influenced by the geometric properties of the gap and its location under the antenna element. Another advantage of aperture coupling is its higher bandwidth than direct contacting.
- the module is structured on two sides for optimum operation: the side facing the antenna contains the ground area for the antenna and the feed line with the associated coupling columns; the ground surface also shields the parasitic radiation of the feed network and thus ensures the high polarization purity of the Arrangement.
- the side facing away from the antenna contains the feed network.
- further active and passive circuits such as antenna amplifiers, filters, etc. can be integrated in an advantageous manner on this page.
- This embodiment of the module is of course also suitable for direct contacting of the antenna element.
- a particularly advantageous embodiment of the module consists in providing it integrated into a housing, which can be attached to the plastic part in a defined manner, for example by snap-in or adhesive technology.
- the spatial alignment of the coupling slots to the antenna element introduced is thus advantageously defined and the attachment of the module is simplified.
- easy interchangeability of the module is guaranteed, for example in the case of hardware updates.
- the antenna is designed as a microstrip antenna, an additional ground area is required which, together with the antenna element implemented as a patch and integrated into the plastic part, forms a resonator.
- This ground surface can be applied to the back of the component using the shaping process.
- This arrangement is particularly suitable for flat components and shows particularly positive properties for the reception of GPS signals.
- ground surface As a metal adhesive film, direct metallization or screen printing.
- FIG. 1 shows a section through a component according to the invention with a directly contacted antenna element.
- Fig. 2 shows a section through an inventive component with aperture coupling.
- the antenna element 1 shows a directly contacted antenna element in the component.
- the antenna element is arranged between the paint film 1 and the back-injection material 3.
- the lacquer film consists of a clear layer la, a color layer lb and the carrier layer lc.
- the antenna element in the form of a patch 2 is arranged between the carrier layer 1c and the back injection material 3.
- the antenna element is provided with a soldering point 6 before the back injection. After the back injection, this soldering point is drilled through the back injection material 3, and the inner conductor 5 of a coaxial line is passed through the bore up to the antenna element 2.
- Termination of the antenna structure is formed by the ground surface 4, which is applied to the back injection material 3.
- the easy finding of the antenna element 2 integrated in the component is made considerably easier by the choice of a transparent back injection material 3.
- FIG. 2 shows a component with an integrated antenna element 2, in which the energy transfer to the antenna element takes place via an aperture coupling.
- the antenna element 2 is arranged between the lacquer film 1 and the back-injection material 3 in the manner described above.
- the ground surface 4 is formed as part of a module 7 attached to the rear of the component.
- the ground surface 4 has a gap 10 through which the magnetic coupling of the antenna element 2 takes place.
- the electrical and electronic components required to control the antenna element 2 are integrated in the module 7.
- latching and holding elements 8 are latching and holding elements 8, which can advantageously be provided in the shaping process by the design of the molding tool.
