Description

Typenschild zur Kennzeichnung eines Gegenstandes für Fahrzeuge Name plate for marking an object for vehicles
Die Erfindung richtet sich auf ein Typenschild der im Oberbegriff des Anspruches 1 angegebenen Art. Ein solches Typenschild wird vor allem bei Fahrzeugen verwendet und enthält fahrzeugspezifische Daten, wie eine Fahrgestellnummer, das Herstellungsjahr des Fahrzeugs und die Art seiner Motorisierung od. dgl..The invention is directed to a type plate of the type specified in the preamble of claim 1. Such a type plate is used primarily in vehicles and contains vehicle-specific data, such as a chassis number, the year of manufacture of the vehicle and the type of its motorization or the like.
Ursprünglich wurde als Typenschild eine metallische Platte verwendet, wo diese Daten eingestanzt oder eingraviert werden und, nach dem Anbringen der Platte am Fahrzeug optisch ablesbar sind. Diese bekannten Typenschilder sind verhältnismäßig leicht zu fälschen. Das Ablesen dieser Daten ist oft umständlich und zeitaufwendig.A metal plate was originally used as the nameplate, where this data is stamped or engraved and can be read off visually after the plate has been attached to the vehicle. These known type plates are relatively easy to forge. Reading this data is often cumbersome and time-consuming.
Es ist bereits eine Plakette für Kraftfahrzeuge bekannt (DE 100 03 881 A I ), auf deren Schauseite ablesbare fahrzeugspezifische Daten aufgebracht sind, beispielsweise in Form von Zulassungs-Informationen. Dazu dient eine Trägerschicht aus Kunststoff, die einseitig aufgebrachte Beschriftungen aufweist. Beidseitig davon sind Klebstoffschichten aufgebracht, mit der die Plakette an einer Anbringungsfläche anklebbar ist. Unter der rückseitigen Klebstoffschicht befindet sich ein Transponder, dessen Antennen in der Klebstoffschicht angeordnet sind. Der Transponder ist dabei in einer Zwischenschicht angeordnet welche, wie der Transponder, zunächst von einem Schutzpapier abgedeckt wird. Zum Ankleben der Plakette an derA badge for motor vehicles is already known (DE 100 03 881 AI), on the front side of which readable vehicle-specific data are applied, for example in the form of registration information. For this purpose, a carrier layer made of plastic is used, which has inscriptions applied on one side. Adhesive layers are applied to both sides of it, with which the badge can be glued to an attachment surface. There is a transponder under the adhesive layer on the back, the antennas of which are arranged in the adhesive layer. The transponder is arranged in an intermediate layer which, like the transponder, first of all is covered with a protective paper. To stick the badge on the

Ferner ist ein Fahrzeug-Identifikationssystem bekannt (DE 196 07 294 A I ) bei dem fahrzeugspezifische Daten mittels eines Induktionsverfahrens in einem Chip gespeichert, abgerufen oder geändert werden. Dieser Chip kann dabei direkt in Fahrzeugteile, wie einen Motorblock oder wie Stoßfänger, integriert werden. Das Einschrauben in vorgefertigte Hohlräume ist ebenfalls vorgesehen.Furthermore, a vehicle identification system is known (DE 196 07 294 A1) in which vehicle-specific data are stored, called up or changed in a chip by means of an induction method. This chip can be integrated directly into vehicle parts, such as an engine block or like a bumper. Screwing into prefabricated cavities is also provided.
Der Erfindung liegt die Aufgabe zugrunde, ein zuverlässiges Typenschild der im Oberbegriff des Anspruches 1 genannten Art zu entwickeln, das zwar bequem ablesbar ist, dessen Daten aber dennoch gut geschützt sind. Dies wird erfindungsgemäß durch die im Kennzeichen des Anspruches 1 angegebene Maßnahmen erreicht, denen folgende besondere Bedeutung zukommt.The invention has for its object to develop a reliable nameplate of the type mentioned in the preamble of claim 1, which is easy to read, but whose data is still well protected. This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following special meaning.
Bei der Erfindung hat die Platte eine Doppelfunktion. Sie umfasst nicht nur die optisch ablesbaren Daten auf ihrer Schauseite, sondern dient zugleich zur Aufnahme eines Transponders. Der Transponder wird im Inneren der Platte in eine schalenförmige Aufnahme eingelegt, welche dann von einem Deckel verschlossen wird. Man erhält ein Kombinationsprodukt, bestehend aus Platte, Transponder und Deckel. Die Platte besteht aus temperaturbeständigem thermoplastischem Kunststoff, der durch Schmelzverbindungen für eine Einlagerung des Transponders im Platteninneren sorgt. Mindestens einige der fahrzeugspezifischen Daten werden dann auf elektromagnetischem Wege in den Speicher des im Typenschild integrierten Transponders eingegeben und können, nach der Befestigung des Typenschilds am Fahrzeug, von außen elektronisch abgelesen werden. Dieses Ablesen kann durch elektronische Lesegeräte sehr zuverlässig und schnell ausgeführt werden. Die Elektronik im Transponder kann nur eine verschlüsselte Eingabe der Daten in den Speicher erlauben, weshalb nachträglich auf elektronischem Wege eine Fälschung der fahrzeugspezifischen Daten im Transponder unmöglich ist. Dadurch ist eine fälschungssichere Ausbildung des Typenschildes erreicht. Das Ablesen des Speichers im Transponder ist von außen sehr schnell und zuverlässig möglich. Weitere Maßnahmen und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, der nachfolgenden Beschreibung und den Zeichnungen. In den Zeichnungen ist die Erfindung in einem Ausführungsbeispiel dargestellt, nämlich ein Typenschild für ein Fahrzeug. Es zeigen:In the invention, the plate has a dual function. It not only includes the optically readable data on its face, but also serves to hold a transponder. The transponder is placed in the inside of the plate in a bowl-shaped receptacle, which is then closed by a cover. A combination product consisting of a plate, transponder and cover is obtained. The plate is made of temperature-resistant thermoplastic, which uses melted joints to store the transponder inside the plate. At least some of the vehicle-specific data is then electromagnetically entered into the memory of the transponder integrated in the rating plate and can be read electronically from the outside after the rating plate has been attached to the vehicle. This reading can be carried out very reliably and quickly by electronic readers. The electronics in the transponder can only allow encrypted entry of the data into the memory, which is why it is subsequently impossible to electronically forge the vehicle-specific data in the transponder. This ensures that the rating plate is tamper-proof. The memory in the transponder can be read quickly and reliably from the outside. Further measures and advantages of the invention result from the subclaims, the following description and the drawings. In the drawings, the invention is shown in one embodiment, namely a nameplate for a vehicle. Show it:

Das erfindungsgemäße Typenschild besteht, wie bereits erwähnt wurde und aus Fig. 1 zu ersehen ist, aus drei Bestandteilen 10, 20, 30. Der erste Bestandteil ist eine Platte 10 aus temperaturbeständigem, thermoplastischem Kunststoff 1 1 . Die Platte 10 ist auf ihrer Schauseite 12 zwar im wesentlichen eben, aber auf ihrer Rückseite 13 profiliert. Die Profilierung ergibt sich zunächst aus einem rückseitigen Rahmen, in dessen mittlerem Bereich eine Vertiefung 15 angeordnet ist. Diese Vertiefung 15 ist dimensionsmäßig dem zweiten Bestandteil des Typenschilds, nämlich einem Transponder 20, passend gestaltet. Der Transponder 20 hat, wie Fig. 4 zeigt, einen kreisartigen Umriss 21 und beinhaltet in seinem Inneren, wie an sich bekannt ist, außer elektronischen Bauteilen, wie elektromagnetischen Spulen, auch noch einen nicht näher erkennbaren Speicher, der auf elektromagnetischem Wege geladen und abgelesen werden kann.As has already been mentioned and can be seen from FIG. 1, the type plate according to the invention consists of three components 10, 20, 30. The first component is a plate 10 made of temperature-resistant, thermoplastic synthetic material 11. The plate 10 is on its front side 12 essentially flat, but profiled on its back 13. The profiling initially results from a rear frame, in the central region of which a recess 15 is arranged. This recess 15 is dimensionally designed to match the second component of the nameplate, namely a transponder 20. The transponder 20, as shown in FIG. 4, has a circular outline 21 and, as is known per se, contains in its interior, in addition to electronic components such as electromagnetic coils, also an undetectable memory which is charged and read by electromagnetic means can be.

Dicke 22 ist die Vertiefung 15 in der Platte 10 ausgebildet. Durch den Rahmen 14 und die Vertiefung 15 erhält die Platte 10 im mittleren Bereich eine schalenförmigeThickness 22 has the recess 15 formed in the plate 10. The frame 14 and the recess 15 give the plate 10 a bowl-shaped shape in the central region
Form, wodurch ein offenes Gehäuse 16 entsteht.Form, whereby an open housing 16 is formed.
Die Platte 10 besitzt in ihren Endbereichen zwei mit Durchbrüchen versehene Lappen 17, die, wie Fig. 5 zeigt, zur Befestigung an einer nur im Längsschnitt und Ausbruch gezeigten Karosserie 40 dienen. Die Lappen 17 sind gegenüber der Schauseite 12 tiefer gesetzt und liegen in Übereinstimmung mit Stegen 18, welche die Plattenenden auf der Rückseite 13 U-förmig umfassen und dadurch zur erwähnten Profilierung beitragen. Auch der Rahmen 14 ist stellenweise mit Füßen 19 versehen, die im Gebrauchsfall, wie Fig. 5 zeigt, sich an der Oberfläche 41 der Karosserie 40 abstützen. Dadurch entstehen, wie Fig. 5 zeigt, Frei räume 42 zwischen der Karosserie 40 und der Platte 10, wodurch Farbpigmente beim Beschichten der Karosserie 40 auch unterhalb des befestigten Typenschilds die Oberfläche 41 der Karosserie 40 überziehen können.The plate 10 has in its end regions two flaps 17 provided with openings, which, as shown in FIG. 5, serve for fastening to a body 40 shown only in longitudinal section and cut-out. The flaps 17 are set lower relative to the front side 12 and lie in correspondence with webs 18 which enclose the plate ends on the back 13 in a U-shape and thereby contribute to the profiling mentioned. The frame 14 is also provided in places with feet 19 which, in use, as shown in FIG. 5, are supported on the surface 41 of the body 40. This results, as shown in FIG. 5, clearances 42 between the body 40 and the plate 10, whereby color pigments when coating the body 40 can also cover the surface 41 of the body 40 below the attached nameplate.
Nach der Fertigstellung der profilierten Platte 50 wird zunächst, wie durch den Pfeil 23 in Fig. 1 verdeutlicht ist, der Transponder 22 in die Aufnahme 1 5 des Gehäuses 16 eingelegt. Dabei ist der erwähnte Speicher des Transponders 20 zunächst im wesentlichen leer. Nach der Montage in der Aufnahme 1 5 ist die Rückseite des Transponders im wesentlichen bündig. Das erlaubt die Montage des dritten Bestandteils 30.After completion of the profiled plate 50, the transponder 22 is first inserted into the receptacle 15 of the housing 16, as is illustrated by the arrow 23 in FIG. 1. The aforementioned memory of the transponder 20 is initially essentially empty. After mounting in the receptacle 1 5, the back of the transponder is essentially flush. This allows the third component 30 to be assembled.
Der dritte Bestandteil 30 des erfindungsgemäßen Typenschilds ist ein Deckel 30. der hier aus einer planparallelen Scheibe besteht und seinerseits aus einem temperaturbeständigen, thermoplastischen Kunststoff 3 1 ausgebildet ist. Der Deckel 30 hat, wie Fig. 3 erkennen lässt, einen Umriss 33, welcher den Dimensionen des Rahmens 14 angepasst ist. Das Gleiche gilt für die Dicke 32 des Deckels 30. Nach der Montage 23 des Transponders 20 wird auch der Deckel im Sinne desThe third component 30 of the type plate according to the invention is a cover 30, which here consists of a plane-parallel disk and is itself made of a temperature-resistant, thermoplastic 3 1. As can be seen in FIG. 3, the cover 30 has an outline 33 which is adapted to the dimensions of the frame 14. The same applies to the thickness 32 of the cover 30 The assembly 23 of the transponder 20 is also the cover in the sense of
Pfeils 34 von Fig. 1 in das Gehäuse 16 eingeführt. Dieser Zustand ist in Fig. 5 zu erkennen.Arrow 34 of FIG. 1 inserted into the housing 16. This state can be seen in FIG. 5.
Ausweislich der Fig. 5 füllt der eingeführte Deckel 30 den Innenraum des Gehäuses 16 zwar aus, doch überragen die erwähnten vorspringenden Füße 1 9 die Rückseite 35 des montierten Deckels 30. Allseitig um die Aufnahme 1 5 herum berührt sich die Vorderseite 37 des Deckels mit dem erwähnten Gehäuseboden 24. Auf diese Berührungszonen 25 zwischen 10 und 30 wird nun, wie symbolisch in Fig. 5 verdeutlicht ist, eine Laserstrahlung 26 geleitet. Dies ist möglich, weil der Laserstrahl 26 in einem Frequenzbereich liegt, für welches zwar der Kunststoff 3 1 des Deckels 30 im wesentlichen transparent, aber der Kunststoff 1 1 der Platte 10 absorbierend ist. Es kommt daher in der Berührungszone 25 zu einem Aufschmelzen der Kunststoffmassen 11 und/oder 31. Das Ergebnis ist eine endlose linienförmige, durch Punktung in Fig. 6 verdeutlichte Schweißnaht 27 zwischen den beiden Teilen 10, 30. Die Schweißverbindung 27 umschließt den in der Aufnahme 15 befindlichen Transponder 20 allseitig und sorgt somit für einen mediendichten Einschluss.5, the inserted cover 30 fills the interior of the housing 16, but the protruding feet 1 9 protrude beyond the rear 35 of the mounted cover 30. All around the receptacle 1 5, the front 37 of the cover touches with the mentioned housing base 24. A laser radiation 26 is now directed onto these contact zones 25 between 10 and 30, as is symbolically illustrated in FIG. 5. This is possible because the laser beam 26 is in a frequency range for which the plastic 3 1 of the cover 30 is essentially transparent, but the plastic 1 1 of the plate 10 is absorbent. Therefore, the plastic masses 11 and / or 31 melt in the contact zone 25. The result is an endless line-shaped weld seam 27 between the two parts 10, 30, which is illustrated by dots in FIG. 6. The weld connection 27 encloses the one in the receptacle 15 located transponder 20 on all sides and thus ensures media-tight containment.
Statt einer Verschweißung 27 durch Laserstrahlung 26, könnte auch ein Reibschweißen oder eine Ultraschallschweißung zwischen den beiden Bestandteilen 10, 30 des erfindungsgemäßen Typenschilds erfolgen. Weil der Speicher im Transponder 20 noch leer ist, kann die Wärmeentwicklung beim Herstellen der Schweißverbindung 27 keinen Schaden machen. Erst nach dem Zusammenbau des erfindungsgemäßen Typenschilds aus den drei Teilen 10, 20, 30 erhält man ein Kombinationsprodukt 28 gemäß Fig. 5 und 6, das nachträglich mit den erforderlichen Daten 29, 39 versehen wird.Instead of welding 27 by laser radiation 26, friction welding or ultrasonic welding could also take place between the two components 10, 30 of the type plate according to the invention. Because the memory in the transponder 20 is still empty, the heat development during the production of the welded connection 27 cannot do any damage. Only after the type plate according to the invention has been assembled from the three parts 10, 20, 30 is a combination product 28 according to FIGS. 5 and 6 obtained, which is subsequently provided with the required data 29, 39.
Das erfindungsgemäße Kombinationsprodukt 28 enthält zwei zueinander wenigstens bereichsweise übereinstimmende, aber doch sehr unterschiedliche Datensätze 29, 39. Der eine Datensatz 29 wird auf mechanischem Wege auf der Schauseite 12 der Platte 10 eingebracht. Im vorliegenden Fall bestehen sie aus Kerben 36, die in das Material der Platte 10 durch Laserlicht eingebrannt werden. Der andere Datensatz 39 wird auf elektromagnetischem Weg in den Speicher des Transponders 20 eingegeben. Bei der Erfindung werden beide Datensätze 29 und 39 gleichzeitig erzeugt bzw. eingegeben. Für die Eingabe des elektronischen Datensatzes 29 können dabeiThe combination product 28 according to the invention contains two data sets 29, 39, which at least in some areas correspond to one another but are very different. The one data set 29 is introduced mechanically on the front side 12 of the plate 10. In the present case they consist of notches 36 which are burned into the material of the plate 10 by laser light. The other data record 39 is entered into the memory of the transponder 20 by electromagnetic means. In the invention, both data sets 29 and 39 are generated or entered simultaneously. For the entry of the electronic data record 29 can
Codierungen genutzt werden, die es nur berechtigten Personen erlauben, denCodings are used that only authorized persons allow the

Durch die Maßnahmen gemäß Anspruch 1 1 ergibt sich eine höhere Fälschungssicherheit des erfindungsgemäßen Produkts. The measures according to claim 1 1 results in a higher security against forgery of the product according to the invention.
