DE202016003677U1 - The plastic inner wing of a motor vehicle in the winter while driving through a individually and flexibly electrically controlled self-adhesive foil heater to de-ice and ice-free - Google Patents

Abstract

The present invention relates to the application of the plastic inner fender of a motor vehicle in the winter while driving through an individually and flexibly electrically controlled self-adhesive film heater to de-ice and ice-free.

Description

technical description

One for each motor vehicle Individually and flexibly made one-piece or multi-part electrically controlled and self-adhesive film heater which is glued to the respective plastic inner fender and emits their radiant heat in winter operation in a predetermined direction. This radiant heat keeps the inner fender free of ice while driving.

State of the art:

utility Models DE 20 2013 003 318.5 and DE 20 2013 102 992.0 are known but not technically mature.

Technical problem:

These heating foils release their heat in both directions and are not individually tailored for each motor vehicle and inner fender. It was also not considered that various openings on the inner fender should be left free (eg for charge air, oil, water and brake cooling or mounting holes for mounting) must be. In winter driving the motor vehicle slush and ice accumulates between the plastic inner fender and tires, the slush freezes while driving or overnight. When driving z. B. put the tire potholes in the frozen inner fender, in addition, the steering radius is significantly affected. This can lead to a dangerous impairment for the driver and other road users. The installation of such a heating foil in a motor vehicle must be tested by the TÜV type, EU approved (E1) and approved.

Solution:

With the self-adhesive electrical film heater custom-made for each type of vehicle, the area to be heated on the inner fender can be delivered over a large area in a predetermined direction. Furthermore, in this custom-made film heating from the outset important openings when gluing the inner fender released z. B. for intercooler, oil, water and brake cooling or mounting holes for mounting.

The installation of such a film heater in a motor vehicle must be tested by the TÜV type, EU-certified (E1) and approved. The supply voltage and control of the film heater must be made via the motor vehicle 12 V + 24 V, or via CAN bus. The system adapts and regulates the required heating power of the heating foil to the respective outside temperatures.

Achieved benefits:

By heating the film heater on the inner fender, the frozen slush can defrost while driving. An impairment for the driver in traffic by frozen inner fender can thus be excluded.

Exemplary embodiment Drawing:

The standard plastic inner wing ( 5 ) are used on the motor vehicle ( 4 ) removed and cleaned. Then the individual foil heating ( 2 ) glued on the respective inner fender ( 3 ). Now the inner fenders can be reinstalled and the electrical connections of the foil heater ( 1 ) are connected to the motor vehicle.
