Description

The invention relates to a water deflector for arrangement in front of a windshield of a motor vehicle.

A generic water deflector is from the German patent application DE 10 2007 017 168 A1 known. The water deflector serves to protect an area between a hood and the windshield from dirt and water, in particular by passing water into drainage channels.

An object of the invention is to provide a water drain for a motor vehicle, which controls water directed to an underlying component, in particular a gutter.

This object is solved by the features of the independent claims. Further advantageous embodiments are the subject matter of the dependent claims, which can be combined in a technologically meaningful way with each other, which can be partially adjusted effects that go beyond the sum of the individual effects. The description, in particular in conjunction with the drawing, additionally characterizes and specifies the invention and shows further advantageous features of the invention.

• – einen Schrägungsbereich und
• – einen Trennbereich, welcher zumindest teilweise wasserdurchlässig ist und der insbesondere in einer Fahrzeughochachse oberhalb von einer Ablaufrinne angeordnet ist, und
• – eine an einer Unterseite des Trennbereichs angeordnete Abtropfkante, welche dazu ausgestaltet ist, Wasser in Richtung der Ablaufrinne abzuleiten.

Accordingly provided is a Wasserabweiser for arrangement in front of a windshield of a motor vehicle, the Wasserabweiser comprising:

• A skew area and
• A separation area which is at least partially permeable to water and which is arranged in particular in a vehicle vertical axis above a gutter, and
• - A arranged on an underside of the separation region drip edge, which is designed to drain water in the direction of the gutter.

The separation area serves to protect an area below it from dirt and external influences and to pass water through it. The separation area is arranged above the gutter, so that water gets into the gutter mainly by gravity. The water can flow down the slope area and penetrate the separation area. On flat objects can water drops, due to the surface tension of the water, get stuck and reach areas where water is undesirable. At the drip edge, however, the water droplets are redirected and discharged in a controlled manner onto the gutter, wherein the gutter can be part of a service panel.

According to a preferred embodiment, the drip edge is formed from a web which extends orthogonally to a region of the water deflector.

This drains the water from a bottom of the water deflector. The drained water can not flow back to the underside of the water deflector due to gravity. At an distal end of the web, an edge is arranged, at which the surface tension, such as a drop of water, is interrupted, so that gravity can detach the water droplet.

According to a further advantageous embodiment, the web tapers with increasing distance from the water deflector. As a result, at the distal end of the web is a relatively narrow area where larger drops of water can no longer hold, so that they drip from the web or the drip edge here.

According to a further advantageous embodiment separation area is arranged at an angle between 25 ° and 65 °, in particular between 30 ° and 60 °, more preferably between 35 ° and 55 ° to the slope region. This configuration means that water without having to be redirected, the slope region can flow down into the separation area. The discharge of the water can be improved.

According to a further advantageous embodiment, the drip edge is arranged at a lower curvature region between the bevel region and the separation region. Without a drip edge, water could flow into areas where it can not be drained. The arrangement of the drip edge is effectively prevented. The arrangement depends in particular on the particular arrangement and configuration of the components, in particular the gutter and the water deflector. Thus, it may be expedient to move the drip edge in the direction of the separation area, so that water does not reach the curvature area between the separation area and the bevel area at all, but is deposited beforehand down into the gutter.

Preferably, in the curvature region, the beveling region merges into the separation region over a radius of curvature of 1 mm to 50 mm, in particular of 10 mm to 40 mm. Water, which flows downwards on the slanting area, reaches the separating area via the slanted area, which it largely penetrates due to its inertia.

According to a further advantageous embodiment, beveling area is formed from a spherically curved plane, wherein the plane extends with a deviation of at most 15 ° with respect to a main extension direction of the windshield. As a result, the sloping region can form a flat continuation of the windshield. Water can pass unhindered from the windscreen into the separation area and be discharged. In addition, it can be exploited by the speed, which reaches water when flowing down from the windshield.

According to a further advantageous embodiment, the drip edge extends over the entire separation area. Thus, in any area in which water can reach the bottom of the water separator, flowing around the curvature region can be effectively prevented.

According to a further advantageous embodiment, the drip edge is angled following a curvature of the separation area in the direction of a vehicle vertical axis at an angle between 15 ° and 55 °, in particular between 20 ° and 50 °, particularly preferably between 25 ° and 45 °. As a result, water can flow along the drip edge itself, at least in the edge areas, until it reaches horizontal areas where it can drip off well.

Preferably, the water deflector described herein is disposed on a motor vehicle for bridging an intermediate region between a hood and a windshield.

An exemplary embodiment will be explained in more detail below with reference to the drawing. Show it:

1 schematically a water deflector with a water-permeable separation area and with a drip edge, and

2 : schematically in a sectional side view of a service panel arranged over a water deflector.

1 shows in a side view a cut in an X, Z plane intermediate area 1 between a windshield 2 and a hood 3 , Water, which is in the intermediate area 1 can pass through a water deflector 4 targeted to an underlying gutter 5 be directed. This is due to the water deflector 4 a water-permeable separation area 6 arranged. The separation area 6 has a perforation for this purpose 7 on. The perforation 7 is designed to allow water to pass through and keep debris such as leaves out of the area below. For this purpose, the perforation 7 openings 8th which are just so big that water does not adhere to it due to capillary action or its surface tension.

The gutter 5 is at a service panel 9 arranged. The service panel 9 closes an area between the hood 3 and a dashboard, not shown. The gutter 5 opens on both sides in likewise not shown drainage holes.

The water deflector 4 also has a skew area 10 on which in extension of the windshield 2 is arranged. The windshield 2 extends in a main extension direction H. The skew area 10 preferably forms a flat continuation of the windshield 4 , which is usually retracted to the two sides of the vehicle to the rear, ie in the negative X direction.

The skew area 10 goes in a curvature area 11 around a radius of curvature R in the separation area 6 above. An angle a between the skew area 10 and the separation area 6 may be between 25 ° and 65 °, in particular between 30 ° and 60 °, particularly preferably between 35 ° and 55 °. In the depression formed in this way, dirt can accumulate worse than in sharp-edged transitions. Basically, the skew area 10 and the separation area 6 to the location of the gutter 5 adapt. An arrangement of the separation region is preferred 6 above the gutter 5 ,

Water passing through the perforation 7 in the separation area 6 could get on a bottom 12 of the water deflector 4 around the curvature area 11 flow around and get into areas where water is undesirable. Therefore, the curvature area 11 on the bottom 12 a drip edge 13 on. The drip edge 13 indicates in a normal operating position of the vehicle downwards in the direction of gravitational acceleration, ie in the negative Z direction. The water gets at the drip edge 13 diverted and to a rejuvenated area 14 passed, where it can drain. The drip edge 13 is a broad bridge in style 15 designed. The jetty 15 has a distal end d and a proximal end p. The jetty 15 extends orthogonally from the curvature area 11 and tapers with increasing distance from the curvature area 11 , At its distal end d, the bridge points 15 an edge 17 which facilitates the dripping off of water, since water can adhere badly to sharp edges.

2 shows a water deflector 4 from a frontal view. To clarify the spatial arrangement are the separation area 6 as well as the drip edge 13 dashed lines, although in the illustrated view by the hood 3 facing area 14 (see also 1 ) are concealed. The jetty 15 , which is the drip edge 13 forms, extends in a vehicle transverse direction (+/- Y) at least over the perforation 7 or the separation area 6 , In peripheral areas 16 is the drip edge 13 angled upwards at an angle b in the direction of the Z-axis. Water, which is in the border areas 15 on the drip edge 13 so can the dripping edge 13 drain down and not at the bottom 12 of the water deflector 4 accumulate.

Although some possible embodiments of the invention have been disclosed in the foregoing description, it is to be understood that numerous other variants of embodiments exist through the possibility of combining all of the cited and further all of the obvious technical features and embodiments. It is further understood that the embodiments are to be understood as examples only, which in no way limit the scope, applicability and configuration. Rather, the foregoing description would suggest a suitable way for the skilled person to realize at least one exemplary embodiment. It should be understood that in an exemplary embodiment, numerous changes in the function and arrangement of the elements may be made without departing from the scope and equivalents disclosed in the claims.
