Definitions

• Remote-controllable device in particular remote-controlled central locking for motor vehicles
• the invention relates to a remotely controllable device, in particular a remotely controllable central locking system for motor vehicles according to the preamble of claim 1.
• Such antenna arrangements for a radio-controllable locking system in a motor vehicle are arranged, for example, in the region of a window opening.
• the manufacturer supplies the corresponding electronic devices with their components housed in a housing, together with an antenna.
• the antenna is usually designed as a plug-in part that can be plugged into the housing.
• the antenna is then usually laid in the vehicle in the form of a freely routable wire according to the general state of knowledge in such a way that the best possible reception effect is achieved.
• the object of the present invention is to improve such a remotely controllable device, in particular a remotely controllable central locking system.
• the invention now creates a significant improvement with comparatively simple means that was not predictable in this way.
• the solution according to the invention essentially lies in the fact that the electronics module, ie the remotely controllable device is accommodated on a carrier or a housing as according to the prior art, but now a dimensionally stable or rigid antenna is used which is inherently stable at the front or is held or constructed on a rigid or dimensionally stable carrier. It would be quite conceivable that the antenna itself is bendable, but nevertheless consists of dimensionally stable material, i.e. not like a non-dimensionally stable flexible wire. In addition, however, a flexible wire can also be used as an antenna if it is at least held or laid on a carrier in such a way that it can ultimately be called an overall dimensionally stable antenna. It is crucial that when the antenna is installed by the motor vehicle manufacturer when the electronic device is installed in the correct position, the antennas are all routed the same way.
• the antenna is preferably not connectable to the device as a plug-in module, but rather is permanently and permanently connected to the device. This forms a compact unit that can be handled in a uniform manner, in which the antenna to the module is located in a fixed spatial assignment and therefore the same installation conditions can always be achieved on site.
• the antenna is laid or formed longitudinally on the carrier or housing in a predetermined way.
• the antenna can preferably even be installed running around parts of the carrier or housing, for example in the manner of a U in plan view.
• the antenna can be embodied, for example, on a carrier material in the sense of a substrate, for example in the form of a stripline arrangement.
• the stripline can optionally be designed to follow different paths, for example comparable to a zigzag structure or comparable to a rectangular pulse, that is to say quasi-meandering.
• helical antennas are also conceivable, which are preferably fixed on a carrier which penetrates the helical windings or holds them on the outside.
• a single, jointly manageable combination device is necessary, consisting of the actual device comprising the electronic components, e.g. the receiver and the antenna. This also shortens the installation time on site.
• connection between the antenna housing and the antenna element is preferably formed without an additional plug connection or as an HF line, thereby avoiding additional losses and also preventing failure. is probably reduced by a defective cable or a defective plug.
• rattling noises of the antenna can also be avoided by the remote-controllable device according to the invention, since the antenna cannot strike body parts of the vehicle when the vehicle vibrates.

• a combination device 1 is shown in a schematic perspective view, which shows a remote-controlled central locking.
• This combination device 1 consists of an electrical device 3, ie, in the illustrated embodiment of a remote central locking module 3, which is usually built in a housing 5 or on a carrier 5 to-1.
• the combination device 1 comprises an antenna 7, which in the exemplary embodiment shown can consist of a wire, a stranded wire or a tube, hollow tube etc. in a schematic plan view according to FIG.
• the antenna 7 is preferably inserted into the electrical device 3 without plug contact and electrically contacted there.
• the entire arrangement of the electrical device 3 with its housing 5, which can also be designed as a housing shell 5, is provided or mounted with the antenna 7 on a common base plate 5 ', that is to say generally on a carrier 5'. This ensures that the antenna 7, even if it would consist of a deformable wire or a braid may be placed permanently in a fixed predetermined and straight running in the embodiment alignment by on the support or the base plate 5 1 provided fixations.
• This assembly 13 can then be installed accordingly in a motor vehicle, a corresponding electrical connection being available via a connection 15 on the housing 5 for outputting the demodulated data signal in order to ultimately e.g. to operate the central locking.
• a modified exemplary embodiment is shown in a schematic perspective illustration with reference to FIG. This results in a particularly compact construction with a comparatively long antenna element 7 in that the antenna element 7 is guided from an exit point 19 with respect to the electrical device 3 in a top view, quasi U-shaped around the housing 5, and to an exemplary embodiment shown according to FIG. 2 with the formation of two kink points 21 which form approximately 90 °.
• the carrier 5 or the base plate 5 ′ can also be part of a cover for the housing 5 for receiving the electrical device 3.
• the support or base plate 5 ' is then dimensioned larger in plan view than the actual housing 5 or the housing shell 5. As indicated in FIG.
• the antenna 7 can now be placed in a pre-positioned position, for example in the form of a wire or a strand, and holding-fixing nipples 9 or webs 9 are again preferably provided for this purpose, so that the wire is inserted here and held permanently in place.
• the antenna element can, for example, also be moved longitudinally by a further distance, at least once more, at a further kink, also on the end face of the housing.
• FIGS. 3a and 3b A modification to FIG. 3 is shown in FIGS. 3a and 3b.
• Figure 3 namely, the antenna 7 is laid essentially on the longitudinal side of the housing 5 parallel to this housing side on the support or base plate 5 1 .
• FIG. 3a shows a side view of the housing along the arrow representation 10 in FIG. 3, but with the difference from FIG. 3 that the antenna 7 on the top of the housing 5 is laid lengthways to the top.
• the antenna is laid on the underside of the housing, with corresponding nipples or webs 9 again being provided in these cases for fixing the antenna or the antenna strand.
• an inverted-F antenna 7 has been used, the rest of the laying of the antenna element 7 largely corresponding to that of FIGS. 2 and 3.
• the antenna 7 can also be formed as a strip conductor element or as a conductive antenna element left behind by etching, which can have a wide variety of shapes.
• a rectangular basic structure comparable to a meandering structure, is selected.
• a wire coil can also be used as the antenna element.
• This too is preferably held and fastened on a carrier or a base plate, in particular a printed circuit board.
• the coil element can be held by a carrier or the printed circuit board with a mandrel-like element which projects through the interior of the coil element.
• FIG. 7 a modified embodiment is shown, wherein the base plate 5 1 extends on all sides over the housing 5 of time, can be so mounted on said base plate 5 'also a dipole antenna.
• the dipole antenna 7, which again consists, for example, of wires or strands, can also be held again by means of fixings 9 (fixing webs, fixing knobs and the like).
• fixings 9 fixing webs, fixing knobs and the like.
• a loop antenna has been used, which is laid on the base plate 5 'around the entire housing 5, in which, in addition to the dipole antenna representation according to FIG. 7, the free dipole ends through a connecting section are closed to the loop. Further modifications are possible.
• the further fixations on the base plate 5 'for holding the antenna are not shown in detail.
