Definitions

  • the invention relates to the field of motor vehicles, and more particularly to the strengthening of the front structure of motor vehicles in the event of frontal impacts.
  • connection reinforcements formed from two elements. elongated extending transversely to the direction of extension of the side members and between which is fixed a jack support.
  • the object of the invention is to improve the strengthening of the front part of the underbody structure of motor vehicles while limiting the increase in mass, and this in a simple and economical manner.
  • the invention relates to a motor vehicle comprising, on each lateral side a front foot with an elbow profile; a longitudinal underbody connected to the front leg; a reinforcement disposed in the front foot and extending longitudinally from a front wall of said foot to the bottom of the body; remarkable in that the reinforcement is a deep drawing comprising a longitudinal main wall inclined by less than 30 ° with respect to the vertical, a lower edge opposite a rebate of the lower junction of the front leg and the rocker panel , and an upper edge resting on the upper walls of the front leg and the rocker panel.
  • G inclination of the main wall relative to the vertical is greater than 15 °.
  • the upper edge of the stamp comprises a longitudinal support wall on the upper walls of the front leg and the rocker panel, said longitudinal wall forming a square with the main wall.
  • the bracket forms a hollow directed laterally towards the interior of said vehicle.
  • the stamped part comprises a tab projecting downward from the lower edge, said tab being housed in the lower junction rebate of the front leg and the rocker panel, so as to serve as a zone of a vehicle lifting jack.
  • the tab is located on a front half of the stamping.
  • the stamping comprises a front wall for pressing on the front wall of the front leg, said front wall forming a square with the main wall.
  • the front support wall on the front wall of the front foot forms a square with the longitudinal support wall on the upper walls of the front foot and the rocker panel.
  • the stamped part comprises a rear wall for bearing on a vertical wall of the rocker panel, said rear wall forming a square with the main wall and comprises a leg for supporting on said vertical wall of the underbody.
  • the main wall comprises several openings intended to lighten the stamping.
  • the measures of the invention are advantageous in that the reinforcement forms a one-piece element easily achievable by stamping and ensuring optimized reinforcement insofar as it extends continuously and essentially plane between the lower and upper walls of the front leg and underbody. Besides making it possible to counter the bending movements of the front part in the event of a severe frontal impact, it can also serve as a jack support.
  • This invention is all the more interesting that the pooling of the reinforcement function and the lifting function on a single piece makes it possible to adjust the addition of mass to what is necessary.
  • FIG 1 shows a perspective view of a lower portion, with a reinforcement, of a front structure of a vehicle according to the invention.
  • FIG 2 shows a view of a cross section II-II of the lower portion of the front structure of Figure 1.
  • FIG 3 illustrates a view of a cross section III-III of the lower portion of the front structure of Figure 1.
  • FIG. 1 is an enlarged view of the front part of the reinforcement of the lower portion of the front structure of FIG. 1.
  • FIG. 1 is an enlarged view of the rear part of the reinforcement of the lower portion of the front structure of FIG. 1.
  • FIG. 1 is a perspective view of a lower portion of the front structure 1 of a motor vehicle.
  • this portion 1 corresponds to the right side of the vehicle (not shown in its entirety), it comprises a front leg 3, with an angled profile, to which the rocker panel 5 is connected, and also a reinforcement 7 of frontal impact.
  • This reinforcement 7 is in fact placed in the front leg 3 and extends longitudinally from a front wall 9 of the latter as far as the rocker panel 5.
  • It is in particular formed of a perforated longitudinal main wall 11, of an upper edge 13 and a lower edge 15.
  • the main wall 11 is inclined by less than 30 ° relative to the vertical, and advantageously by more than 15 °.
  • the upper edge 13 is supported on the upper walls 17 of the front leg 3 and the rocker panel 5, the connection between the parts being produced by welds of electrical resistance.
  • the lower edge 15 is in turn positioned vis-à-vis a lower junction rebate 19 of the front leg 3 and the rocker panel 5, and it in particular comprises a tab 21 which projects downwards.
  • This tab 21 is in fact located on a front part of the reinforcement 7 and is housed in the lower joining rebate 19 of the front leg and the rocker panel, so as to serve as a support zone for a lifting jack (not represented).
  • Figure 2 is a view of a cross section of the lower portion of the front structure 1 of Figure 1 along the axis II- IL
  • This view shows that the upper edge 13 of the reinforcement 7 further comprises a longitudinal wall of support 23 on the upper walls 17 of the front leg 3 and of the rocker panel 5.
  • This longitudinal support wall 23 in particular forms a square with the main longitudinal wall 11 of the reinforcement 7, which constitutes a hollow directed laterally towards the interior of the vehicle.
  • the connection of the longitudinal support wall 23 with the upper walls 17 of the front leg 3 and the rocker panel 5 has the function, during a severe frontal impact, of making it possible to counter the bending movement of the front structure 1 of the vehicle automobile.
  • the tab 21 which acts as a jack support 21 and which is arranged projecting from the lower edge 15 of the reinforcement 7 on the lower junction rebate 19 of the front leg 3 and of the bottom body 5.
  • a hole 25 for fixing the jack (not shown) is positioned at the bottom of this tab 21, this hole 25 also serves to fix a hook for clamping during road, rail or sea transport.
  • Figure 3 is a view of a cross section of the front structure 1 of Figure 1 along the axis III-III. This section is located in the second half of the reinforcement 7, at the level of an opening 27 of the longitudinal main wall 11.
  • several openings are distributed over the main wall 11 of the reinforcement 7 (FIG. 1), they are in particular intended mainly to lighten it but also to allow the welding tongs to be left during the fitting of the different parts.
  • FIG 4 shows an enlarged view of the front part of the reinforcement 7 of the lower portion of the front structure 1 of Figure 1.
  • This front part of the reinforcement 7 comprises a front support wall 29 on the front wall 9 of the front foot 3.
  • This support wall 29 forms in particular a square with the main longitudinal wall 11 of the reinforcement 7, but also a square with the longitudinal support wall 23 on the upper walls 17 of the front leg 3 and the rocker panel 5 During a severe frontal impact, the connection of the support wall 29 with the front wall 9 of the front foot 3 has the function of resuming the support of the front foot 3 at the moment of the pushing of the front wheel (not shown) of the vehicle on the bottom of the front leg 3.
  • FIG. 5 represents an enlarged view of the rear part of the reinforcement of the lower portion of the front structure 1 of FIG. 1.
  • This rear part of the reinforcement 7 is in consists of a rear support wall 31 on a vertical wall 33 of the rocker panel 5, more precisely of the rocker panel reinforcement 5, the connection between the parts being produced by welds of electrical resistance.
  • the rear support wall 31 in fact forms a square with the main longitudinal wall 11 of the reinforcement 7, and it is also provided with a support lug 35 located on the vertical wall 33 of the reinforcement underbody 5.
  • the connection of the rear support wall 31 with the vertical wall 33 of the underbody reinforcement 5a like the longitudinal support wall 11 of the reinforcement 7, for its function to counter the bending movement of the front structure 1 of the motor vehicle.
  • the reinforcements located in the lower portion of the front structure of a vehicle according to the invention have the advantage of being in a single piece, mainly vertical, extending between the lower and upper walls of the rocker panel and the front leg, in this case at the lower junction rebate and the upper walls of said rocker panel and said front leg.
  • the reinforcement provides, in addition to the reinforcement function, the role of jack support.
  • This invention is even more advantageous in that these integrated jack support reinforcements, because of their low mass delta, can in fact also adapt as much in the environment of thermal vehicles as of electric vehicles in order to provide the service with severe frontal impact.
