Description

The invention relates to an optical carrier for attaching and aligning a radar sensor on a motor vehicle. The invention further relates to a method for producing an optical carrier. The invention also relates to a device for producing an optical carrier. The invention also relates to a radar module for a motor vehicle.

State of the art

For monitoring a front area of a motor vehicle by means of an assistance system, radar modules are conventionally placed behind the company symbol of the respective manufacturer on a body of the motor vehicle. In front of the radar module, a module cover of the radar module is integrated into a radiator grille, through which the radar beams of a radar sensor of the radar module can pass. Current radar module housings are manufactured using die-cast aluminum and each have a thermoplastic cap on one of the front and back to seal off dirt and moisture. The radar module housing is fastened to sheet metal carriers, which are in turn screwed to the body of the motor vehicle, in front of the radiator of the motor vehicle. The carriers cover a large area where the air can not flow to the cooler.

The DE 20 2006 015 996 U1 discloses a motor vehicle radar system with a radar sensor, wherein the radar sensor is connectable by means of a holding frame with a motor vehicle, wherein between the radar sensor and the holding frame, an intermediate frame is arranged, with which the radar sensor is firmly connected. The radar module cover and the radar module are thus fastened independently of each other, and any misalignments or displacements of the radar sensor can cause the radar sensor to malfunction.

Disclosure of the invention

The present invention provides an optics carrier for attaching and aligning a radar sensor on a motor vehicle, which is formed by a trough-shaped, overmolded with a plastic semifinished product, wherein the optics carrier integrally formed means for attaching and aligning the radar sensor, wherein the optics carrier provided on one of the motor vehicle Cover is attachable to form a radar module housing.

The present invention further provides a method of making an optics carrier for mounting and aligning a radar sensor on a motor vehicle. The method comprises arranging a semifinished product in an injection mold of an injection molding machine, fixing the semifinished product in the injection mold, inserting means for attaching and aligning the radar sensor on an ejector of the injection mold and injecting a thermosetting or thermoplastic resin for encapsulating the semifinished product and the means for mounting and aligning the radar sensor for forming a trough-shaped optical carrier with molded-on means for attaching and aligning the radar sensor.

The present invention further provides an apparatus for manufacturing an optical carrier for mounting and aligning a radar sensor on a motor vehicle with an injection molding machine comprising a thermoset injection molding tool, and a roll-to-roll system adapted to pass the semi-finished product through the Lead injection mold.

The present invention further provides a radar module for a motor vehicle. The radar module has an optics carrier for attaching and aligning a radar sensor to a motor vehicle, a radar sensor mounted in the optics carrier, and a cap provided on the motor vehicle, wherein the optics carrier is attached to the cap for forming a Radarmodulgehäuses.

One idea of the present invention is to provide a compact, inexpensive and lightweight optical carrier for optimum positioning of the radar sensor behind a radar module cover, a method for producing the optical carrier, an apparatus for producing the optical carrier and a radar module. The optical carrier is very dimensionally stable even at high temperatures and shocks and maintains tight tolerances on shape and position. In addition, the optimized optics carrier can save material and process steps and thus also reduce the production time.

The optical carrier connects the radar sensor directly to a cap or radar module cover. The optics carrier can thus be optimally positioned before installation in the vehicle. The compact radar module only covers a small area in front of the radiator. When using a semifinished product in the form of an organic sheet of optics carrier is very dimensionally stable even at high temperatures and shocks and holds tight form and position tolerance fields. In the optics carrier a rear cap and means for attaching and aligning the radar sensor is integrated, so that only a front cap must be made separately.

In the case of the use of a semifinished product in the form of a die-cut to fabric or metal mesh track, the semi-finished product is guided by roll-to-roll through the injection mold and cut with a punching device to the predetermined contour. Alternatively, a preformed organic sheet can be inserted into the tool and overmoulded with a thermoplastic. In the case of the use of woven or metal mesh panels can be saved by the reduction of material, process steps and thus manufacturing time in addition by the use of inexpensive thermosetting plastic costs that have a favorable component price result. When all the components are connected together, a compact and lightweight radar module is created, which can be completely replaced and must not be readjusted with regard to misalignment or displacement.
