View Patent ↗A motor vehicle, in particular passenger motorcar, is provided. The motor vehicle includes a side member, a bumper and a crashbox. The crash box includes a main portion extending between a tip of the side member and the bumper and an anchoring portion pushed into an open end of the side member. A support body extends within the anchoring portion between walls of the anchoring portion located opposite each other.
1. A motor vehicle, comprising:
a side member;
a bumper; and
a crashbox including:
a main portion extending between a tip of the side member and the bumper;
an anchoring portion pushed into an open end of the side member; and
a support body that extends within the anchoring portion between walls of the anchoring portion located opposite each other, the support body comprising:
at least one centerpiece aligned transversely to the side member; and
a plurality of flanges angled off the at least one centerpiece, the plurality of flanges bearing against the walls located opposite each other;
wherein the support body further comprises an offsetting portion, wherein the offsetting portion is deformable to a limited degree in a direction that is perpendicular to the walls located opposite each other.
2. The motor vehicle according to claim 1 , wherein the crashbox further comprises two channel-shaped elements which do not touch one another in the anchoring portion.
3. The motor vehicle according to claim 2 , wherein each of the two channel-shaped elements are connected to each other via a second plurality of flanges marginally standing away in the main portion.
4. The motor vehicle according to claim 3 , wherein the walls of the anchoring portion comprise two parallel vertical walls, and wherein one of the two channel-shaped elements comprises a first one of the two parallel vertical walls, and a second one of the two channel-shaped elements comprises a second one of the two parallel vertical walls located opposite the first one of the two parallel vertical walls.
5. A motor vehicle with a side member, a bumper and a crashbox, the crashbox comprising:
a main portion extending between a tip of the side member and the bumper;
an anchoring portion pushed into an open end of the side member; and
a support body that extends within the anchoring portion between walls of the anchoring portion located opposite each other, the support body comprising:
at least one centerpiece aligned transversely to the side member; and
a plurality of flanges angled off the at least one centerpiece, the plurality of flanges bearing against the walls located opposite each other;
wherein the support body further comprises an offsetting portion, wherein the offsetting portion is deformable to a limited degree in a direction that is perpendicular to the walls located opposite each other.
6. The crashbox according to claim 5 , further comprising two channel-shaped elements which do not touch one another in the anchoring portion.
7. The crashbox according to claim 6 , wherein the channel-shaped elements each extend unitarily over the main portion and the anchoring portion.
8. The crashbox according to claim 7 , wherein the channel-shaped elements are connected to each other via a second plurality of flanges marginally standing away in the main portion.
9. The crashbox according to claim 7 , wherein the walls comprise two parallel vertical walls, and wherein one of the channel-shaped elements comprises a first one of the two parallel vertical walls located opposite a second one of the two parallel vertical walls.
10. The crashbox according to claim 5 , wherein the support body is formed from at least one flat material cutting.
11. The crashbox according to claim 5 , wherein the plurality of flanges are angled off from the centerpiece towards an open end of the anchoring portion facing away from the bumper.
12. The crashbox according to claim 5 , wherein the offsetting portion further comprises a first flange and a second flange, wherein the first flange is located opposite the second flange, and wherein the first flange is connected to the centerpiece along a first margin and the second flange is connected to the centerpiece along a second margin.
13. The crashbox according to claim 12 , wherein the plurality of flanges are unitarily connected via a substantially U-bend along a third margin.
14. The crashbox according to claim 12 , wherein the first flange is not connected to the second flange.
15. The crashbox according to claim 12 , wherein the crashbox further comprises two channel-shaped elements which do not touch one another in the anchoring portion; and
wherein a center plane, in which the channel-shaped elements are connected, extends between a subset of the plurality of flanges, wherein the subset comprises flanges of the offsetting portion located opposite one another.
