Abstract

The invention relates to a bumper arrangement 12 for a motor vehicle comprising a cover member 14 mounted to a bumper cross beam 16 by means of an attachment device 18, the bumper arrangement 12 having a variable stiffness depending on a direction of impact of an object (10, Fig. 5) on the bumper arrangement 12, wherein the attachment device 18, by means of which the cover member 14 is mounted to the bumper cross beam 16, comprises at least one protrusion element 24 that allows the cover member 14 to travel a greater distance in relation to the bumper cross beam 16 if the bumper arrangement 12 is impacted by an object (10, Fig. 5) in a direction of a longitudinal vehicle axis A than if it is impacted with an equal force by an object (10, Fig. 5) in a direction angled to the longitudinal vehicle axis A. The arrangement provides greater resistance to low speed impacts from vehicles in an oblique direction, compared to pedestrians in a longitudinal direction.

Description

Bumper Arrangement for a Motor Vehicle The invention relates to a bumper arrangement according to the preamble of patent claim 1.
KR 10 2013 0 129 649 relates to a shock absorbing part which is placed between a steel beam and a bumper cover to absorb shock energy in the case of a low speed collision of a vehicle with an object. The shock absorbing part comprises a body part and a plurality of insert parts. The insert parts are separately placed on the front side of the body part in a lateral direction. The insert parts comprise shock absorbing materials whose rigidity varies to allow the insert part to correspond to stiffness requirements for protecting pedestrians in a collision.
ER 1 798 114 Al reveals an adapting piece intended to be placed on an automobile shock absorber. This adapting piece has a variable stiffness according to longitudinal direction of a sensor and is able to transmit compression force to the sensor when the vehicle is subjected to an impact.
DE 196 33 110 B4 shows a percussion absorber for a motor vehicle with deformation elements of different rigidity. A plastic deformation of the deformation elements having different rigidity can be initiated by impacts of different speeds. A less stiff element is fixed in one energy absorbing zone and another stiffer element can be moved. The stiffer element is held in a parking position outside the shock absorption zone while the vehicle is travelling below a predetermined driving speed. At a higher vehicle speed than the predetermined driving speed the stiffer element is moved into the energy absorbing zone to provide a stiffer percussion absorber together with the less stiff element.
ER 1 986 890 describes a dual stage energy absorber for a motor vehicle bumper. The motor vehicle bumper includes one or more geometric configurations that extend softer energy absorbing surfaces forward in the system while nesting more rigid energy absorbing surfaces more rearward. The more rigid energy absorbing surfaces only come into effect when higher energy impacts occur. To provide such softer and more rigid energy absorbing surfaces, the wall thickness of different components of the motor vehicle bumper may be varied, materials having different stiffness properties may be used and/or different geometries of different sections may be provided. The result is that the stiffness may be altered across the pumper system to match an overall stiffness to the different impact forces of objects colliding with the motor vehicle at different vehicle speeds.
The object of the present invention is to provide a pumper arrangement which matches the requirements of a low speed collision of a motor vehicle in a particularly advantageous manner.
This object is solved by a bumper arrangement having the features of patent claim 1.
Advantageous embodiments with expedient and non-trivial developments of the invention are indicated in the other patent claims.
In order to provide a bumper arrangement, which matches the requirements of a low speed collision of a motor vehicle in a particularly advantageous manner, the attachment device, by means of which the front cover unit is mounted to the bumper cross beam, comprises at least one protrusion element that allows the front cover unit to travel a greater distance in relation to the bumper cross beam if the bumper arrangement is impacted by an object in the direction of the longitudinal vehicle axis than if it is impacted with an equal force by an object in a direction angled to the longitudinal vehicle axis. Such a bumper arrangement is especially safe for pedestrian and especially resistant to damage from other objects in the case of a low-speed impact.
The outer shell of a motor vehicle has to meet several regulatory requirements, which can be mutually conflicting in nature. Pedestrian safety and low-speed damageability are two such conflicting requirements. They especially concern the front and rear bumper of a motor vehicle. A pedestrian safe bumper exhibits a moderately or especially low-stiffness.
On the other hand, low-speed damageability requires an especially stiff bumper. A bumper arrangement with an especially low stiffness will deform and yield in the case of an impact with a pedestrian. The result is that the pedestrian may be protected from bodily harm as the force of the impact is absorbed by the bumper arrangement. A bumper arrangement with low-speed damageability is required to not deform in the case of a low-speed impact. Otherwise, deformation of the bumper arrangement will require a repair or exchange of motor vehicle parts.
The underlying idea of the invention is the directional dependency of an object impact on the bumper arrangement. A pedestrian impact on the vehicle is typically head-on along the longitudinal vehicle axis. Other low-speed impacts usually occur at an angle to the pumper arrangement, especially on the corner with an angle of approximately 30°to the longitudinal vehicle axis. The advantage of the bumper arrangement according to the present invention is, that if the bumper arrangement is impacted by an object in the direction of the longitudinal vehicle axis the cover member can travel further in relation to the bumper cross beam. Thus the bumper arrangement can be deformed more in reaction to the impact than if the bumper arrangement is impacted in a direction angled to the longitudinal vehicle axis. This means that the bumper arrangement has a lower stiffness along the longitudinal vehicle axis than along an axis angled to the longitudinal vehicle axis. This provides an especially good protection of pedestrians during an accident involving a motor vehicle having such a bumper arrangement, as the pedestrian impact can be expected to be in the direction of the longitudinal vehicle axis.
If the bumper arrangement is impacted by an object with equal force in direction angled to the longitudinal vehicle axis the cover member travels a shorter distance in relation to the bumper cross beam. This means the cover member will deform less and the overall bumper arrangement stiffness is greater in the case of an angled impact. This means the bumper arrangement can absorb the shock of a slow speed impact by an object such as lanterns, other cars or other rigid objects at an angle to the longitudinal vehicle axis with none or especially low damage. For example, the bumper arrangement can protect the motor vehicle especially well against impacts due to mishandling of the vehicle during parking manoeuvres without suffering permanent damage. Overall an advantage of the bumper arrangement is that it can meet regulatory requirements concerning pedestrian safety and low-speed damageability especially well.
In another advantageous embodiment of the invention, the attachment device allows free movement of the cover member in the direction of the longitudinal vehicle axis and blocks the movement of the cover member angled to the longitudinal vehicle axis. This embodiment provides an especially high pedestrian safety and low-speed damageability.
Furthermore, it protects sensitive and expensive parts positioned at the corner of the vehicle, such as headlamps and fog lights, especially well.
In another advantageous embodiment of the invention, the attachment device comprises at least one pin member attached to the cover member. The at least one pin member is an especially cost-effective embodiment of an attachment device. It can be used similar to a bearing device to guide travel of the cover member along the longitudinal vehicle axis and hinder or block travel of the cover member in the direction angled to the longitudinal vehicle axis. For example, the pin member can have the shape of a rod.
Corresponding to the previous advantageous embodiment of the invention, the bumper cross beam can comprise a corresponding hole to each of the at least one pin member.
This corresponding hole constitutes a corresponding half of a bearing device to the pin member. This allows the pin member to slide through the corresponding hole, especially in the direction of the longitudinal vehicle axis while blocking movement in an angled direction. This is an especially cost-effective and reliable construction to provide the means to allow the cover member to travel a greater distance in relation to the bumper cross beam if the bumper arrangement is impacted by an object in the direction of the longitudinal vehicle axis, than if it is impacted with an equal force by an object in a direction angle to the longitudinal vehicle axis.
In another advantageous embodiment of the invention, the pin member extends in the direction of the longitudinal vehicle axis. This corresponds to the requirement that the cover member should travel a greater distance along the longitudinal vehicle axis than at an angled axis in the case of object impacts with an equal force and different angles.
In a further advantageous embodiment of the invention, the pin member has a variable cross section along the direction of the longitudinal vehicle axis. This allows the bumper arrangement to have a variable stiffness depending on the force of an object impact -especially directly relating to the speed of an impact. For example, this can be achieved by two means. The pin member deforms more with higher speeds, so that the deformation reaches regions with a bigger cross section resulting in the pin member having a higher stiffness and also a lower deformability in those cross sections.
Alternatively or additionally the corresponding hole to the pin member does not increase in cross section. This results in an increase of friction on the pin member as it further travels along the longitudinal vehicle axis. This means the greater the distance the pin member has travelled in the corresponding hole the greater the resistance is against a further travel of the cover member in relation to the bumper cross beam.
Another further advantageous embodiment of the invention, the pin member is formed in one piece with the cover member. This allows for especially cost-effective manufacturing and assembly of the bumper arrangement.
Further advantages, features and details of the invention derive from the following description of a preferred embodiment as well as from the drawings. The features and feature combinations previously mentioned in the description as well as the features and feature combinations mentioned in the following description of the figures and/or shown in the figures alone can be employed not only in the respectively indicated combination but also in any other combination or taken alone without leaving the scope of the invention.
The drawings show in: Fig. 1 a schematic representation of an object impacting in a direction of a longitudinal vehicle axis on a bumper arrangement for a motor vehicle; Fig. 2 a schematic representation of an impact by an object in a direction angled to the longitudinal vehicle axis on the bumper arrangement according to Fig. 1; Fig. 3 a sectional view of the bumper arrangement according to Fig. 1, comprising a cover member mounted to a bumper cross beams by means of an attachment device; Fig. 4 a perspective view on the bumper arrangement according to Fig. 3; Fig. 5 a perspective view of the bumper arrangements according to Fig. 4, which is being impacted by an object in the direction of the longitudinal vehicle axis; and Fig. 6 a perspective view of the bumper arrangement according to Fig 4, which is being impacted by an object in a direction angle to the longitudinal vehicle axis.
In the Figures same elements having the same function are equipped with the same reference signs.
Fig. 1 and 2 shows schematically two different impact cases of an object 10 on a bumper arrangement 12 for a motor vehicle. The bumper arrangement 12 comprises a cover member 14 mounted to a bumper cross beam 16 by means of an attachment device 18, which can be seen in Fig. 3. The bumper arrangement 12 has variable stiffness depending on the direction of impact of an object 10 on the bumper arrangement. The bumper arrangement 12 shown here is the front bumper arrangement 12 of the motor vehicle, but it could also be the rear bumper.
A bumper arrangement 12, which can also be called a bumper system, has to match two mutually conflicting requirements. One requirement is pedestrian safety. This requirement requires the bumper arrangement 12 to have moderate or low stiffness in the direction of a pedestrian impact. A pedestrian impact is usually expected to be a slow speed impact along the direction of the longitudinal vehicle axis A. The other requirement is low-speed damageability. This is tested through a pendulum impact. This requirement requires the bumper arrangement 12 to have an especially high stiffness in the impact direction which is expected to be angled to the longitudinal vehicle axis A. This high stiffness required for low-speed damageability conflicts with the low stiffness required for pedestrian safety.
Fig. 1 shows in a schematic representation an impact of an object 10 on the corner of the bumper arrangement 12 in the direction of the longitudinal vehicle axis A. The direction of the impact is also represented through arrow 20. This is one of the most common impact directions of pedestrians on a vehicle in an accident. Accordingly, pedestrian safety of a bumper arrangement 12 is also tested in this direction. This is especially the case for pedestrian safety tests of motor vehicles.
Fig. 2 shows in a schematic representation one of the most common impact directions of low speed impacts of other objects 10 on the motor vehicle. In the case of Fig. 2, the object 10 impacts on the bumper arrangement 12 at an angle of 30°to the longitudinal vehicle axis A. The direction of the impact is also represented through arrow 22. For example, such an impact of an object 10 on the bumper arrangement 12 can usually occur when the vehicle collides with another vehicle during a parking manoeuvre. To provide an especially high protection of sensitive and expensive vehicle components such as headlights, the bumper arrangement 12 should be especially stiff in such a case.
As can be seen in the sectional view of Fig. 3 and the perspective view of Fig. 4, the cover member 14 is attached to the bumper cross beam 16 by means of an attachment device 18 that comprises two protrusion elements 24. The attachment device 18 allows the cover member 14 to travel a greater distance in relation to the bumper cross beam 16 if the bumper arrangement 12 is impacted by an object 10 in the direction of the longitudinal vehicle axis A, than if it is impacted with an equal force by an object 10 in the direction angled to the longitudinal vehicle axis A. The cover member 14 can travel a greater distance if it is impacted in the direction according to arrow 20 than if it is impacted in the direction according to arrow 22 in relation to the bumper cross beam 16.
That means the bumper arrangement 12 will deform more if it is impacted by the object in the direction of the longitudinal vehicle axis A than if it is impacted with an equal force by the object 10 in the direction angled to the longitudinal vehicle axis A. For the common collision direction of a pedestrian with the motor vehicle the bumper arrangement 12 has an especially low stiffness and high deformability. In the case of the object 10 impact during low-speed manoeuvres angled to the longitudinal vehicle axis A the bumper arrangement 12 has an especially high stiffness and a low deformability. This means the bumper arrangement 12 is especially safe for pedestrian and especially resistant to damage from other objects 10 in the case of a low-speed impact.
The attachment device 18 allows free movement of the cover member 14 in the direction of the longitudinal vehicle axis A and blocks a movement of the cover member 14 angled to the longitudinal vehicle axis A. The attachment device 18 comprises two pin members 26 attached to the cover member 14. The bumper cross beam 16 comprises two corresponding holes 28 to the two pin members 26. This allows the pin members 26 to slide through the corresponding holes 28 in the direction of the longitudinal vehicle axis A, while the holes 28 block movement of the pin members 26 in other directions. This is similar to a bearing and offers nearly zero stiffness in the direction of the longitudinal vehicle axis A. In directions angled to the longitudinal vehicle axis A this bearing like attachment of the cover member 14 to the bumper cross beam 16 offers a high stiffness as it blocks the movement of the pin members 26. This so called locking efficiency is improved with the number of protrusion elements 24.
Fig. 5 shows in a perspective view the case of the object 10 impacting on the bumper arrangement 12 angled to the longitudinal vehicle axis A in a slow speed collision. The pin members 26, which are shaped like rods, get locked in the holes 28 and are barely moved by the impact. This results in the cover member 14 travelling only a very short distance in relation to the bumper cross beam 16 due to the impact. Overall the cover member 14 is barely deformed and will protect sensitive vehicle component such as the headlights very well. In the best case scenario, even the cover member 14 does not need to be repaired after such a low-speed collision with the object 10.
Fig. 6 shows the object 10 impacting in the direction of the longitudinal vehicle axis A. This represents a very common low-speed collision of a motor vehicle with a pedestrian.
In this case, the pin members 26 can free slide through the corresponding holes 28. This results in a very low overall stiffness of the bumper arrangement 12 and the cover member 14 travelling a great distance in relation to the bumper cross beam 16. This also results in a high deformation of the cover member 14 itself. In the case of a pedestrian impact this deformation is beneficial as it may prevent bodily harm of the pedestrian.
The bumper arrangement 12 has a variable directional stiffening arrangement for pedestrian safety and low-speed damageability of a motor vehicle. The bumper arrangement 12 takes advantage of the fact that the optimal stiffness, which is conflicting for pedestrian safety and low-speed damageability requirements, especially at the corner portion of the vehicle, is directional dependent. This also results in significant freedom in designing the vehicle, as positioning of expensive parts such as headlamps and fog lights of a vehicle can be chosen especially free without compromising on the pedestrian safety and low-speed damageability ratings of the vehicle.
