[0001] The present disclosure relates to a vehicle front structure for a motor vehicle and a motor vehicle including the vehicle front structure. Background art
[0002] Motor vehicles including similar vehicle front structures are described in the prior art.
[0003] DE 10 2017 124 590 A1 relates to a crossmember arrangement for a motor vehicle, which has an upper crossmember and a lower crossmember arranged below it in the installation position, wherein the upper crossmember and the lower crossmember each extend over most of the vehicle width in the transverse direction of the motor vehicle and are coupled to each other via a connecting tab arranged in the vertical direction of the motor vehicle, so that the upper crossmember, the lower crossmember and the connecting tab are manufactured in one piece and are made of the same material as an extruded profile.
[0004] EP 4 001 022 A1 relates to a bumper arrangement for a motor vehicle, which has a crossmember that can be coupled to the motor vehicle via a crash box and is made in one piece of the same material, in particular an extruded forming member having a hat-shaped cross-section. The crossmember is configured to extend obliquely downward in the vertical direction of the motor vehicle in the corresponding end regions, and the end regions are configured to be annular.
[0005] DE 20 2021 103 264 U1 relates to a bumper arrangement for a motor vehicle, which has an upper main crossmember and a lower auxiliary crossmember, the main crossmember can be coupled to the motor vehicle via a crash box, wherein the main crossmember and the auxiliary crossmember are coupled to each other via a vertical tie rod. The main crossmember and the auxiliary crossmember extend at least partially bent around a vertical axis, wherein the main crossmember and the auxiliary crossmember have different radii of curvature from each other. The auxiliary crossmember is offset backward in the longitudinal direction of the motor vehicle relative to the main crossmember in the direction of the motor vehicle. The auxiliary crossmember has an intermediate section that is offset with respect to the vertical direction, and the main crossmember and the auxiliary crossmember are configured to be in one piece with the vertical tie rod and made of the same material.
[0006] Based on the changing requirements in collision accidents, it is necessary to further develop these conventional structures. Summary of the invention
[0007] Against the background of this prior art, the task of the present disclosure is to provide a device that is suitable for enriching the prior art.
[0008] This task is solved by the features of the independent claims. The content of the dependent claims and the subclaims are optional further improvement solutions of the present disclosure.
[0009] Accordingly, the task is solved by a vehicle front structure for a motor vehicle.
[0010] The vehicle front structure can be understood as the following part of the motor vehicle, which is arranged in front of the passenger compartment of the motor vehicle in the longitudinal direction of the motor vehicle.
[0011] The vehicle front structure includes a deformation element on the right side in the width direction of the motor vehicle and a deformation element on the left side in the width direction of the motor vehicle.
[0012] These deformation elements are arranged spaced apart from each other in the width direction of the motor vehicle here. Left and right refer to the viewing direction from the longitudinal direction of the motor vehicle. The deformation element can also be called a crash box.
[0013] The vehicle front structure includes a continuous cross member in the width direction of the motor vehicle, which connects the deformation elements on the right side and the left side to each other and is arranged in front of the deformation elements on the right side and the left side in the longitudinal direction of the motor vehicle.
[0014] In other words, the continuous cross member is fixed not only to the deformation element on the left side but also to the deformation element on the right side with its side located behind in the longitudinal direction of the motor vehicle and extends without interruption from left to right (or vice versa) between these two deformation elements and optionally extends beyond these deformation elements in the width direction of the motor vehicle.
[0015] The continuous cross member can be connected via the deformation elements to a longitudinal beam on the left side in the width direction of the motor vehicle and a longitudinal beam on the right side in the width direction of the motor vehicle respectively. These longitudinal beams extend backward from their respective deformation elements in the width direction of the motor vehicle, that is, towards the passenger compartment.
[0016] The vehicle front structure includes additional cross members. It is conceivable that the additional cross members extend substantially parallel to the continuous cross member.
[0017] The vehicle front structure includes a vertical tie rod on the right side in the width direction of the motor vehicle and a vertical tie rod on the left side in the width direction of the motor vehicle. These vertical tie rods connect the continuous cross member to the additional cross members respectively.
[0018] In other words, the continuous cross member and the additional cross members are arranged spaced apart from each other in the height direction of the motor vehicle and are connected to each other or to one another on the right side by a vertical tie rod on the right side in the width direction of the motor vehicle and on the left side by a vertical tie rod on the left side in the width direction of the motor vehicle.
[0019] It is conceivable that the respective vertical tie rods are connected to the continuous cross member and / or the additional cross members by screwing and / or welding.
[0020] The vertical struts are each configured as L-shaped when viewed in the longitudinal direction of the motor vehicle.
[0021] In other words, it is proposed to reduce the vertical struts known from the prior art from U-shaped to L-shaped.
[0022] Thereby, it can be prevented that the vertical struts, or the struts for vertically connecting the cross members, cause an air flow obstruction in the region between the main cooling zone formed by the cooler and the brake cooling ducts in front of the valve control device. In addition, it can be achieved that the deformation zone is not reduced due to the horizontal struts during a collision in the lower leg region. In addition, when sealing the air guiding device of the vehicle front structure with soft components, the hitherto required expenditure can be reduced.
[0023] The possible further improvements of the vehicle front structure described above will be explained in detail below.
[0024] It is conceivable that the upper part of each vertical strut located in the height direction of the motor vehicle extends vertically, and the lower part of each vertical strut located in the height direction of the motor vehicle extends horizontally.
[0025] In addition, it is conceivable that the lower horizontal part of each vertical strut extends outwards to the left and right respectively in the width direction of the motor vehicle starting from the upper vertical part of each vertical strut.
[0026] The additional cross member can be implemented in a two-part manner in the width direction of the motor vehicle. It is conceivable that the additional cross member extends outwards to the left and right respectively in the width direction of the motor vehicle starting from a left and a right, optionally lower, longitudinal beam located in the width direction of the motor vehicle.
[0027] It is conceivable that the lower horizontal part of each vertical strut is respectively mounted on the left and right parts of the two-part cross member.
[0028] The vehicle front structure can have a cooler between the deformation elements arranged on the right and left in the width direction of the motor vehicle.
[0029] This cooler can form a so-called main cooling zone, which can be arranged above the additional cross member and / or the continuous cross member in the height direction of the motor vehicle.
[0030] The additional cross member can be implemented in a two-part manner in the width direction of the motor vehicle, such that the cross member is only arranged laterally of the cooler in the width direction of the motor vehicle.
[0031] In other words, the left or right part of the two-part crossbeam can be arranged entirely laterally of the cooler in the vehicle width direction and not connected to each other in the vehicle width direction, so that the two-part crossbeam does not extend in the region which is arranged in the vehicle width direction between the left and right vertical struts. Thus, in this region, the two-part crossbeam is interrupted.
[0032] This can lead to the cancellation of the so-called second load path via the additional crossbeam, which conventionally exists in addition to the so-called first load path via the continuous crossbeam. This can contribute to further strengthening the above-described effect of the solution according to the present disclosure.
[0033] The vehicle front structure can include a valve control device and an air guide device located on the right in the vehicle width direction and an air guide device located on the left in the vehicle width direction.
[0034] The air guide device located on the right in the vehicle width direction and the air guide device located on the left in the vehicle width direction can be spaced apart from each other in the vehicle width direction.
[0035] The air guide device can be provided for an extended cooler or a cooler provided in addition to the cooler described above.
[0036] The vertical strut located on the left in the vehicle width direction can be arranged in the vehicle width direction between the valve control device and the air guide device located on the left in the vehicle width direction.
[0037] The vertical strut located on the right in the vehicle width direction can be arranged in the vehicle width direction between the valve control device and the air guide device located on the right in the vehicle width direction.
[0038] The valve control device can be arranged below the crossbeam in the vehicle height direction.
[0039] The valve control device can be arranged in the vehicle width direction between the air guide device located on the right in the vehicle width direction and the air guide device located on the left in the vehicle width direction.
[0040] The continuous crossbeam can be arranged above the additional crossbeam in the vehicle height direction.
[0041] The continuous crossbeam can be arranged at substantially the same height as the additional crossbeam in the vehicle longitudinal direction.
[0042] The vertical strut can be arranged in the vehicle longitudinal direction in front of the continuous crossbeam and the additional crossbeam.
[0043] Furthermore, the present disclosure relates to a motor vehicle comprising the above-described vehicle front structure.
[0044] The motor vehicle can be a passenger vehicle, such as a car, and / or a commercial vehicle, such as a truck.
[0045] The content described above regarding the vehicle front structure similarly also applies to the motor vehicle and vice versa. BRIEF DESCRIPTION OF THE DRAWINGS
