Method for producing element for vehicle body part comprising improved defrosting device

Abstract

A method according to the present invention comprises producing a blank (11) made of plastic, said blank comprising at least one receptacle (15) on a first face (16); pre-positioning a connecting member (14) relative to the blank (11), the connecting member comprising a first end (21) accessible from the side of the first face (16) of the blank (11) and a second end (22) accessible from the side of the second face (19) of the blank (11); positioning a heating rail (12) on a first face (16) of the blank (11); fastening a connecting portion (20c) of the rail (12) to a first end (21) of the connecting member (14); clamping the first end (21) of the connecting member (14) and the connection (20c) of the rail (12) against each other and welding them together by providing electrical energy; positioning a first end (21) of the connecting member (14) in the receptacle (14), and overmolding an additional layer (13) of plastic.

Description

technical field [0001] The invention relates to the field of manufacturing elements made of plastic intended to be mounted on body parts of motor vehicles. Many modern vehicles are equipped with plastic body elements which can be mounted on, for example, rear tailgates, door sides, front and rear bumpers, roofs, etc. Background technique [0002] In particular, since the introduction of driver assistance systems, various types of sensors have been required to be placed on certain body parts made of plastic in order to measure representative external physical parameters of the external environment of the motor vehicle. The totality of the values ​​of these parameters forms information available in real time about the vehicle environment. [0003] Therefore use body elements that are attached to the body parts, for example with radome The function of the sensor is to protect and hide the electromagnetic wave-transparent element of the sensor. [0004] For example, bumpers ...

AI Technical Summary

Problems solved by technology

[0010] Such an implementation does not protect the connection plate and the conductor track against possible attacks, such as corrosion, from the inner surfaces of the elements for the body parts after installation on the vehicle

Vibration and vibration can also alter and / or damage the defrost system in the long run, especially the connections to the connectors that allow power to the defrost system

In addition, the presence of conductive pins complicates the molding of elements for car bodies, since such pins must remain partly outside the molded area in order not to be covered by plastic material but retain their conductive properties
