Definitions
- the invention relates to a rear crash element for the rear bumper of a motor vehicle in the area of the license plate, with an attached to the cross member of the motor vehicle impact element, behind, seen in the direction of travel of the motor vehicle, a shock receiving element is arranged, wherein the element behind the bumper fascia is arranged and with a
- Plastic cover such as a horn cover or the like, is covered.
- the invention is based on the object, a rear-crash element after the
- the preamble of claim 1 further such that a breakthrough for the baffle element on the bumper fascia omitted, the impact surface of the baffle element to the cross member and the bumper fascia is increased, so that the introduced energy is better absorbed and the baffle can be freet be set free best possible the shock absorbing element behind the
- the rear crash element with respect to the shock absorbing element should be tolerance-free.
- the baffle element is a plastic part, which covers a large area, almost the entire height of the license plate recess, on the inside of the bumper fascia, preferably via a gap, and the shock absorbing element from the outside to the front of the bumper fascia, in alignment with the baffle element, is placed.
- the impact surface of the impact element to the cross member and the bumper cover is increased, so that the introduced energy is better absorbed.
- the impact element By forming the impact element as a plastic part, this can be designed more freely and therefore best support the shock absorbing element behind the panel. Since the shock absorbing element is located only between the bumper fascia and the horn fairing and is no longer fixedly mounted on the vehicle, no mounting clearances in the X direction (tolerances) between the horn fairing and the impact need to be accommodated. be considered element. Also obtained by eliminating the clipping better stability of the panel.
- the impact receiving element includes in an advantageous embodiment, an at least single-layer foam core.
- This foam core is expediently an EPP foam (expanded polypropylene).
- the foam core is reinforced with a reinforcing member in front of the foam core, fitting to the bumper fascia.
- the reinforcing member is in a special embodiment, a plastic plate.
- the reinforcing member may be any member having a higher strength than the foam core.
- the foam core may also have a multilayer structure, with the layer facing the bumper cladding having a higher strength or rigidity.
- the baffle element and the impact receiving element may be provided with honeycomb structures in the direction of impact.
- the impact receiving member fills the cavity between horn trim and bumper fascia via tuning ribs.
- the voltage applied to the bumper fascia surface of the impact member is reinforced with a reinforcing plate which is fixed to the baffle element. This allows better absorption values to be achieved.
- the reinforcing plate is a metal plate, in particular an aluminum plate.
- the invention will be explained in more detail with reference to figures.
- FIGS 1 to 4 show the prior art.
- Figure 1 shows a rear-side bumper cover 1 of a motor vehicle with a number plate 3 and a rear crash element, of which, however, only the outer horn panel 2 can be seen.
- Figure 2 shows a motor vehicle to which the bumper cover 1 is attached.
- the license plate well 3 and the horn cover 2 are clearly visible.
- FIG. 3 shows a view of the rear crash element according to FIGS. 1 and 2.
- This consists of an aluminum profile 5 placed on the cross member 4, on which in turn a PUR-RIM horn pad 6 is placed on the bumper side.
- a recess in the bumper cover 1 is provided / milled, through which the aluminum profile 5 is guided.
- a plastic covering in the form of a horn covering 2 or the like is attached above the horn pad 6 projecting from the bumper covering 1.
- the plastic cover may also be formed as a one-piece, matched to the underlying Hornpad 6 bumper cover or formed by a license plate.
- Figure 4 shows a section along the line A-A of Figure 2. Like reference numerals also show like parts. Good to see that the aluminum profile 5 is inserted through a recess in the bumper fascia and the horn pad 6 carries. The horn pad 6 is arranged with a low mounting clearance 17 of the horn panel. The horn cover is attached to the bumper cover.
- FIGS. 5 to 7 show the rear crash element according to the invention, FIG. 5 showing a view of the rear crash element and FIGS. 6 and 7 showing two embodiments.
- the attached to the cross member 4 aluminum profile 5 including the Hornpads 6 by a large-scale baffle element 7 made of plastic, hereinafter also called baffle plate, and a one- or two- or multi-part shock absorbing element 8 in the horn panel 2 replaced, wherein the shock-absorbing element 8 from the outside on the
- Front 1 1 of the bumper fascia 1, in alignment with the baffle element 7, is placed.
- the breakthrough for the aluminum profile 5 is eliminated.
- the impact receiving element 8 is a foam core in the illustrated embodiment.
- the impact surface 9 of the impact element 7 to the cross member is increased, so that the introduced energy is better absorbed.
- baffle element 7 is realized in plastic, this can be made more free and therefore best support the foam core behind the bumper cover 1.
- an additional reinforcement can be provided on the baffle element 7 by the addition of a reinforcing plate 12, in this case an aluminum plate.
- This reinforcing plate 12 is placed on the impact surface 9 of the impact element 7 and preferably attached.
- the baffle element 7 facing part 8b of the element 8 in this case consists of a material with a higher Strength, as the behind arranged part 8a of the element 8.
- the part 8b is a plastic plate and the part 8a is a foam core.
- the baffle element 7 and the part 8b are provided with a honeycomb structure in the direction of impact (not shown in the figures).
- a support / attachment of the element 8 is due to the increased weight of the multi-part element 8 to provide.
- the shock-absorbing element 8 and the foam core is designed so that it fills the cavity between the horn panel 2 and bumper cover 1 back on Abstimmrippen.
- the cavity is filled by the shortened foam core and the plastic plate.
- an upright gap 17 " is disposed between the inside of the bumper fascia 1 and the baffle 7 or the reinforcing plate.
