Definitions
- the invention relates to a vehicle with an electrical vehicle electrical system and at least one push button according to the preamble of claim 1.
- Pushbuttons are known for switching certain switching functions in the vehicle electrical system and can be actuated by the user by applying a certain pressure.
- two mutually opposite electrically conductive contact surfaces are provided in the pushbutton, the contacting of which realizes the electrical switching function. At least one of the two contact surfaces is movable between two functional positions, so that the electrical contact can be closed or opened by adjusting the movably mounted contact surface.
- Known pushbuttons in vehicle construction are usually realized with movably mounted components in order to enable the necessary adjustment of the movable contact surface between the two functional positions. Often there is also a spring element provided that the movable component returns to a basic position.
- a disadvantage of these pushbuttons for vehicle construction is that, due to the functional reliability required in vehicle construction, they require a relatively complicated structure even in the event of stronger vibrations and thus cause high manufacturing costs.
- the invention is based on the basic idea of arranging the movable contact surface on a flexible conductor carrier and connecting it to the electrical system by means of conductor tracks running on the flexible conductor carrier.
- This required minimum distance can be maintained in a particularly simple manner by interposing a separating element at least in regions between the line carriers of the two contact surfaces.
- This separating element has recesses corresponding to the arrangement of the contact surfaces, so that when the corresponding actuating force is applied by the user, the contact surfaces can come into contact with one another.
- the required actuating force can also be set by selecting the thickness of the separating element, since the thicker the separating element, the greater the actuating force required to contact the contact surfaces.
- Such pushbuttons for vehicle construction can be produced particularly inexpensively if both contact surfaces are arranged on different parts of a common flexible line carrier.
- the line carrier is then folded over in a folding zone, so that the required relative position of the contact surfaces is created.
- the separating element can be realized in a particularly cost-effective manner if it is formed by an insulator film which is attached to the conductor carrier, in particular glued on, to insulate the conductor paths running on the flexible conductor carrier.
- a coverlay can be laminated onto the line carrier, which has recesses at the locations of the contact surfaces. Due to the layer thickness of the cover layer, the contact areas are sufficiently far apart from one another in the unloaded state so that contacting does not occur. The contact can then be closed by pressing on one of the contact surfaces.
- a further function integration is possible in that the separating element, which is inserted between the two parts of the line carrier having the contact surfaces, is also formed as part of the same line carrier.
- the line carrier is folded over along a second folding zone, as a result of which the separating element comes to rest between the other two parts of the line carrier.
- the parts of the cable carrier folded onto one another may be fixed in their relative position to one another.
- This fixing of the various parts of the line carrier after folding can be achieved by means of a suitable fastening means, such as, for example, by applying an adhesive to suitable fastening points. It is advantageous to use the fastening means at the same time for easier relative positioning of the parts of the line carrier.
- a correspondingly arranged snap-in connection device can be used for this purpose.
- the line carrier itself is in principle arbitrary, as long as sufficient elastic deformability is ensured so that the contact surfaces can be moved relative to one another.
- the line carrier has a multilayer structure with a carrier layer, a line layer and an insulator layer.
- the carrier layer serves to give the conductor carrier sufficient mechanical strength and elastic deformability.
- the line layer which can be designed, for example, in the manner of metallic line tracks arranged on the carrier layer, is used for the electrical connection of the various functional elements to the vehicle electrical system.
- the line layer is covered by the insulator layer, so that undesired short circuits do not occur even when a number of line carriers are stacked or when a line carrier is folded.
- the line carrier can have the parts that have the two contact surfaces and the part of a layer that forms the separating element. If necessary, however, it is also possible that the part of the line carrier forming the separating element has no line layer and no insulator layer and is essentially formed only by the carrier layer. This is because the carrier layer alone is also suitable for ensuring a corresponding distance between the parts of the conductor carrier which are in contact with it.
- the carrier layer is made of a plastic film.
- the push button can be individually positioned in the vehicle, in particular as an extension of a line system. However, the push button can also be integrated into a keyboard field.
- the function for which the pushbutton is used in the vehicle is basically arbitrary. According to a preferred embodiment, the push button is used to actuate an electric window lifter in the vehicle.
- FIG. 1 shows a flexible line carrier for forming a push button in a view from above
- Fig. 2 shows the push button shown from the line carrier according to FIG. 1 in a schematic cross section.
- a flexible cable carrier 01 is shown in the unwound state.
- the line carrier 01 is cut in such a way that three identical parts 02, 03 and 04 are formed.
- the two parts 02 and 03 of the cable carrier 01 are provided with a multiplicity of contact surfaces 05a and 05b which can be connected to the vehicle electrical system of a vehicle via conductor tracks 06 and a connector 07 provided on part 03.
- the cable carrier 01 as shown in FIGS. 1 and 2, can be used to form a push button module with which the electric window regulators of a vehicle can be controlled.
- the part 04 of the cable carrier 01 serves as a separating element and has, in accordance with the arrangement of the contact surfaces 05 on the parts 02 and 03, recesses 08 which allow surface contact of the contact surfaces 05a and 05b.
- part 04 of the flexible cable carrier 02 is first folded inwards in a folding zone 10.
- the recesses 08 provided for this come to rest on the part 03 above the contact surfaces 05a.
- adhesive center points 11 are provided, which are not drawn to scale, but rather enlarged. In fact, the adhesive centers 11 are only so thin that the parts 02, 03 and 04 of the line carrier 01 come to lie essentially over the entire surface.
- the part 02 is folded over in a further folding zone 12, so that the contact surfaces 05b on the part 02 of the line carrier 01 come to lie above the correspondingly provided contact surfaces 05a on part 03 of the line carrier 01.
- Part 02 is also fixed with adhesive points 1 1. If an actuating force is now applied from above in the area of a contact area 05b, the conductor carrier 01 deforms elastically until the contact area 05b comes to rest on the contact area 05a and thereby closes the electrical contact. When the actuating force is removed, the elastic deformation decreases and the electrical contact opens again.
- the line carrier 01 which is shown only schematically in FIG. 2, has an overall three-layer structure.
- the cable carrier 01 obtains the mechanical strength from a carrier layer 13, which can be made of a plastic film, for example.
- a conductor layer 14 is deposited on the carrier layer 13 and is separated from the conductor tion tracks 06 and the contact surfaces 05 is formed.
- the line layer 14 in turn is covered to the outside by an insulator layer 15.
- the insulator layer 15 has cutouts in the area of the contact areas 05b so that the contact areas 05a and 05b can be contacted.
- the part 04 of the line carrier 01 serving as a separating element has no line layer 14 and no insulator layer 15.
- Recesses 16 and 17 are respectively provided on parts 02 and 03 of line carrier 01, so that the folding of line carrier 01 is not hindered by the three-dimensional components 18, for example chips, fitted on part 03 when the pushbutton 09 is formed.
