Definitions

  • the invention relates to an add-on part for a motor vehicle, a motor vehicle with such an add-on part, and a method for production.
  • Such a structure is expensive due to the many individual components required and requires a lot of installation space. In particular, there is no accessibility for contacting in certain installation spaces, so that no electrical function can be guaranteed there.
  • An attachment for a motor vehicle is specified with a Schokör by and at least one fastening element for mechanical fastening of the attachment to the vehicle. Furthermore, an electrical consumer is integrated into the attachment.
  • connecting conductor tracks for electrical connection of the consumer to a vehicle power supply are placed on the main body, which contact the electrical consumer and extend to the fastening element.
  • a motor vehicle is specified with an attachment according to the invention.
  • the attachment is fastened to the vehicle by means of the fastening element by engaging with a counter-fastening element arranged on the vehicle side.
  • the counter-fastening element is also designed as an electrical counter-contact for the connection conductor tracks, so that the electrical load is connected to an electrical or electronic device on the vehicle through the engagement of the fastening element and the counter-fastening element.
  • the procedure includes the steps:
  • the fastening element By guiding the connecting conductor tracks down to the fastening element, this also has a function as an electrical contact for contacting the electrical consumer in addition to the function of mechanical fastening.
  • the corresponding vehicle-side mating fastening element is also designed as an electrical contact and is connected to an electrical or electronic device on the vehicle by means of lines, e.g. connected to the vehicle battery. If the attachment is now fastened to the vehicle, for which purpose the fastening element and the counter fastening element come into engagement with one another, the electrical contact is made at the same time as the mechanical fastening. This configuration eliminates the need to connect a separate cable connector. This reduces the installation space requirement and the parts costs, and the assembly effort is also reduced.
  • conductor tracks are used to create connection options for the electrical consumer on the attachment, almost no additional installation space is required, since the conductor tracks can be made very flat. In addition, the conductor tracks are fixed in place on the attachment, so they cannot slip during assembly, which reduces the risk of damage.
  • the main body has a visible side and an inner side.
  • the visible side is the side that is visible in the installed state, whereas the inside usually faces the vehicle body.
  • the main body preferably defines the external dimensions, in particular especially the contour of the attachment.
  • the main body can hold a plastic, a metal, a glass body or a composite body leg.
  • the main body can in particular have further layers, such as decorative layers, lacquer layers or the like.
  • the electrical consumer is integrated into the add-on part; for this purpose, the electrical consumer is arranged in a stationary manner in or on the main body, e.g. mechanically and / or firmly fixed to it.
  • the connecting conductor tracks contact the consumer and thus provide a connection option for connecting the electrical consumer to an electrical or electronic device, such as a power source or a control device.
  • the electrical consumer can be, for example, a light source such as an LED (light emitting diode).
  • the electrical consumer is a surface heating system for heating or controlling the temperature of the attachment. This can be arranged and fixed on the main body as a heating film or heating textile.
  • the surface heating has a conductor track structure that is applied to the main body.
  • the conductor track structure is designed to heat up when electrical power is passed through it.
  • the conductor track structure can have one or more interconnected conductor tracks.
  • the conductor track structure allows almost unlimited freedom in the design of the resistance element and thus offers a wide range of options for setting the energy input into the heating zone in a targeted manner.
  • heating elements can be implemented for a wide variety of requirements. It can be complex geometries can also be implemented on three-dimensional surfaces. Since not only the connecting conductor tracks but also the surface heating are formed by conductor tracks, the construction height can be kept very low. Production is particularly simple, since the connection lines and the electrical consumer can be produced in a common production step by forming the conductor tracks. This also ensures electrical contact between the connecting conductor tracks and the electrical consumer in a simple and reliable manner.
  • the at least one fastening element is used to mechanically fasten the attachment to the vehicle.
  • the attachment can preferably have two or more fastening elements.
  • the fastening element (s) are connected to the main body, for example welded, glued, screwed to it or preferably formed in one piece on the main body, e.g. in an injection molding process.
  • the fastening element can be a clip or latching element or a clamping element.
  • the fastening element acts together with a corresponding vehicle-side counter fastening element.
  • the counter-fastening element can be part of a vehicle component or an independent component.
  • clips, latching or clamping elements enables a particularly simple assembly by merging the fastening element and Ge counter-fastening element, with an electrical contact being generated at the same time between the connection traces on the fastening element and corresponding contact structures on the counter-fastening element.
  • the fastening element is designed as an element protruding from the inside, and the connecting conductor tracks are arranged on opposite side surfaces of the fastener. This results in better tolerances and an even distribution of forces when making contact with the connecting conductor tracks when connecting by means of the counter-fastening element. The risk of short circuits can be reduced and leakage currents can be kept low.
  • a capacitive sensor arrangement with a further conductor track structure can also be arranged on the main body.
  • the sensor arrangement can be set up, for example, to generate signals by means of which the electrical consumer is switched on or off or various heating levels or heating functions are activated. In this way, an operating element for controlling the electrical consumer can be integrated into the attachment without requiring additional installation space.
  • the sensor arrangement also has sensor connection conductor tracks which extend from the functional conductor track structure to the fastening element.
  • the fastening element also functions as an electrical contact for the sensor arrangement, e.g. to forward the sensor signals to a control device in the vehicle.
  • the vehicle-side Gegenbe fastening element has corresponding contact structures which, in the assembled state, establish an electrical connection to the sensor connection conductor tracks. The sensor signals are then passed on from the contact structures on the counter-fastening element, e.g. via cables, to a control device for the electrical consumer.
  • the fastening element can have further printed conductor tracks in order to realize several or additional signal or supply lines. These can be printed on one side of the fastener be or be arranged distributed on two or more sides.
  • the Schmidt fastening element is then designed with corresponding contact structures for contacting the other conductor tracks.
  • connection conductor tracks which e.g. form the connection conductor tracks, the conductor track structures and / or the sensor connection conductor tracks, can be formed on the main body using conventional methods such as hot stamping or laser (direct) structuring.
  • these conductor tracks are formed by means of printing processes such as, for example, screen printing, flexographic printing, pad printing, inkjet printing and the like, and are printed onto the main body.
  • printing processes such as, for example, screen printing, flexographic printing, pad printing, inkjet printing and the like.
  • Electrically conductive inks such as polymer thick-film inks, in particular silver, copper, aluminum, iron and graphite inks, are suitable for production using printing processes.
  • the conductor tracks can also be tempered after the one-step or multi-step printing process. Such printing techniques can be used to achieve a high level of accuracy with regard to the dimensions and position of the conductor tracks.
