Definitions
- the body panels which must be able to be heated are for example produced with an overmolded heating film.
- This manufacturing imposes a high workload with numerous handling steps.
- a component manufactured in this way can be rendered inoperative and is therefore excluded.
- the area heated by the overmolding of the film used is often located not on the outer surface but inside the component, so that the heating efficiency is limited.
- the use of heating films generally does not allow any optically visible shaping from outside the area located under or behind the heating film.
- German patent DE 10 2016 212 763 B4 generally describes a process for depositing a filament on a substrate.
- the present invention therefore aims to provide a modular plastic component and a method for its manufacture, in which the drawbacks of the prior art are avoided, as well as a possibility of simple and reliable heating of the component modular plastic material obtained in a structurally simple manner.
- the modular plastic component according to the invention intended to solve the aim set out above can in particular be a part of a vehicle, for example a body panel.
- the modular plastic component according to the invention comprises a main component body, at least a first layer of plastic and, at least a second layer of plastic.
- a heating filament is arranged at least partly between the first layer of plastic material and the second layer of plastic material. It is thus possible to produce, according to the present invention, a modular plastic component which can be heated, reliably, with low energy consumption and in a structurally simple manner, in which the possibility of heating is hardly visible.
- a decorative or functional layer can be arranged at least in part between the main component body and the first plastic layer of the modular plastic component.
- This layer can, preferably, be transparent to radar systems and be, in a particularly preferred manner, formed from a colored or coated polycarbonate, being in particular in the form of a film material. It is thus possible to integrate structurally simple, in the modular plastic component which can be heated, a visible decorative element, for example graphic, optically additional on the corresponding visible external surface of the modular plastic component.
- the decorative or functional layer is preferably spaced from the heating filament by the first layer of plastic material, the degradation of the material properties of the decorative or functional layer due to the heat, for example in due to the accelerated aging of the material, can be prevented particularly effectively.
- the first layer of plastic material and / or the second layer of plastic material of the modular plastic component according to the present invention is preferably transparent to radar systems, translucent or transparent.
- An embodiment transparent to the radar systems of the main component body, the first and second plastic layers, and the decorative or functional layer, if necessary, makes it possible to arrange a radar system in a simple manner behind a modular plastic component. suitable for heating.
- the transparency to radar systems which results from the plastics used is preferably further improved by arranging the layers or individual elements of the modular plastic component according to the present invention by complementarity of shapes adjacent to each other, and also by not forming no cavity in the layers or individual elements, which is also obtained by the manufacturing method according to the present invention further described below.
- the preferred relatively thin filament of the heating filament also provides particularly good transparency to radar systems of the modular plastic component according to the present invention.
- the heating filament can be connected to a connection terminal and can thus being supplied with electrical energy through it, the connection terminal preferably extending through the main component body and the first layer of plastic.
- the second layer of plastic can be produced so as to cover also, at least in part, in lateral areas edge of the modular plastic component, the main component body and the first layer of plastic.
- the second layer of plastics material may be made of a flowable plastics material and, more particularly, of a polyurethane.
- the construction of the modular plastic component according to the present invention is particularly stable when the main component body is preferably made of a polycarbonate or a mixture of polycarbonate-based materials (PC + ABS for example).
- the following dimensions and properties can preferably be provided:
- - main component body thickness from 2 to 6 mm
- first layer of plastic thickness from 1 to 4 mm
- - second layer of plastic thickness of 0.2 to 1.0 mm, preferably 0.3 to 0.6 mm, particularly preferably 0.4 mm,
- material metal alloy, for example CuAg10,
- - decorative or functional layer thickness of 0.3 to 0.6 mm, preferably 0.45 mm,
- the present invention also relates to a method for manufacturing the modular plastic component described above, comprising a main component body and several layers of plastic material arranged or formed thereon, in order to achieve the object of the present invention , comprising the following steps:
- a main component body of the plastic component to be made from a plastic material or providing such a main component body, and forming a first layer of plastic material covering at least in part an exposed face of the element carrier, by injecting at least partially a first plastic material behind the exposed face of the main component body;
- the first plastic layer of the plastic component to be manufactured from a first plastic material or providing such a first layer of plastic material, and forming a main component body covering at least partially an exposed face of the first layer of plastic material, by injecting at least partially a plastic material behind the exposed face of the main component body;
- the method according to the present invention makes it possible in particular to manufacture the modular plastic component according to the present invention in an economical and relatively simple manner, as well as in a reliable manner without great handling effort.
- a decorative or functional layer between the main component body and the first layer of plastic before injection from behind, preferably by depositing a film of material in a corresponding injection mold.
- connection terminal can preferably be functionally put in place before injection from behind and the heating filament is then connected to the connection terminal, for example by soldering or welding.
