Technical field

This invention involves a kind of as in claim 1 the preamble part of the mud-guard on vehicle.

Background technology

Based on the fact that the known long ago, in other words, in the pedestrian with the front impact exercise of the part above the first limb or head collision the front cover and/or adjacent a body part, such as the fender and therefore may lead to a serious physical damage, the vehicle manufacturing industry widely to deal with this kind of defect, in order to at least the pedestrian and automobile collision may occur between the physical damage caused by reduced to the minimum.

In this, the principle of the basic rigidity of the fender with the greatest possible pedestrian protection coordinated, in particular in the upper fender at the "flexibility" as large as possible.

Also known, mudguard edge on the ground by means of the so-called energy-absorbing element support. This kind of element for example can be an opening through the side surface of a U-shaped section, this kind of material in the vertical force situation is suitable for being pressed together, thereby achieving the deformation of the energy absorbing stroke. (DE   29   34   060 A1; JP   11321717   A).

Similarly known, existing bump forming or bending the sheet-shaped supporting deformable body, itself in vertical force through the yielding and under the condition of the broken or are pressed together to release the necessary deformation stroke (DE   29   34   060   A1; JP   11321717   A), wherein through a plurality of mounted on a motor vehicle and the longitudinal and mutually independent spaced at a distance apart of the deformation member, also known as the fixed flange can be adjusted this mudguard part of a "softness" (DE   30   47   969   A1; DE   199   59   606   A1).

All of the above-mentioned solutions are common, although the fender parts a given "flexibility", perpendicular to the vehicle fender, however, in the longitudinal direction and the rigidity of the direction can only be through the selection of material and mud guard is adjusted to the thickness of material, so the mudguards of the required rigidity and the desired between the mudguard "softness" sure that there is always a certain compromise.

In order to solve this problem, by DE   199   48   732   A1 known mudguards made of a thin plate with different thickness of material, for example, in accordance with a "special blank technology", wherein the lower dashboard part in order to achieve the desired high strength and has relatively thick and the material thickness of the plate in order to achieve certain of the parts of "flexibility" and having a relatively thin thickness of material. In addition upper mudguard in the vertical direction through a deformable body made of energy-absorbing foam supported on a frame rail. To this solution of the "special blank sheet" of the manufacturing cost is particularly adverse.

And DE   100   09   364   A1 discloses a known mudguard, with its own C referred to above has the deformation member of the profile-shaped section, wherein in order to realize higher in the direction perpendicular to the longitudinal and in the direction of automobile mudguard rigid a plurality of so-called strip-shaped support member perpendicular to the vehicle longitudinally attached to the deformation member, the support member not only with the mudguard is fixedly connected with the inner contour of the deformation of the part and is fixedly connected with the lower leg. In addition a recommendation, support elements viewed in the longitudinal direction of the vehicle in the deformation extends over the entire length of the part. Through these measures can certainly not only through the thin material thickness reaches a certain fender "flexibility", to realize the required mud and rigid, however, because of the deformation member and the support member of the multi-part sexual and increase manufacturing and assembling costs, costs itself the cost is increased. In addition another defect is, the deforming part of the profile-shaped section bar C deformation member itself the elasticity of the so-called "bounce" tendency, the mudguard with a desired edge of the corresponding edges of the front cover on the precise boundaries between the opposing combined.

The content of the invention

Therefore, the technical problem to be solved by the invention is to further improve the prior art and, on the one hand to realize simple and low-cost, in particular perpendicular to the vehicle longitudinal axis and in the direction of the rigid, because on the other hand with a pedestrian collides with the pedestrian impact to the mudguard and the upper part of the vertical component, under the condition of generated to allow for the pedestrians to produce a kind of energy absorption as far as possible.

In addition the invention aims to solve the technical problem is that, to ensure the front edge of the fender edge between corresponding to accurate boundary is sewn.

The technical problem according to the invention combines the claim 1 is characterized in the preamble of this solution is, one extending in the longitudinal direction of the vehicle, essentially follows the inner contour of the base plate in the form of mud is worthy of the plane member is fixed to a mudguard, wherein the fender base fixed on the dashboard, on the one hand and on the other hand, the inner contour of the automobile body is fixed on the supporting member and wherein the mudguard the base has at least one deformation member, and the base are connected into a mud and mud from the supporting member portion of the upper edge and is fixedly connected with the upper edge.

In the present invention improved structure of the deformable part can be formed by the in-out formed on the structure of the base.

In another favorable improvement of the plate in the structure of the base and/or deformation member has a concave, recesses and/or a reinforcement member. In addition according to the invention, said deformation member is provided with one or more given bending point.

The mudguard base includes the deformation member design into a metal plate or plastic molded component is suitable.

In addition a recommendation, the mudguard base horizontally or with a certain angle "α" of the vehicle body from the vehicle the inner contour of the support member relative to the mudguard guiding ascending or descending.

In addition in accordance with the present invention is proposed, in order to fix the mudguard base support member of the vehicle body on the inner contour and mud-guard is provided with one or a plurality of fixed short arm, wherein the fixed short arm almost parallel to the support member or the inner contour of the plate. In this the mudguard base by fixed short arm by welding, bonding or by a mechanical fixing mechanism is fixed on the supporting member. The invention is further characterized in that, the mudguard base by fixed short arm is fixed by bonding on the inner contour of the splash.

Finally, according to the invention the deformation thereof in the number of parts and the length of the longitudinal direction of the vehicle, the deformation member has the reinforcing bead, reinforcing short arm and/or the structure of the bending point, the mudguard by the base has a depressed, notch, reinforcing bead and/or short reinforcing arm structure and the mudguard base body from the vehicle with respect to the mud guard supporting member to begin to guide the inner contour of the angle "α", have to be in accordance with the desired or said support mudguards of the automobile to be perpendicular to the longitudinal direction and in the direction of a certain rigidity and in accordance with the vertical impact force of the collision on the mudguard desired of the human body are determined by the selected speed.
