Definitions
- front blocks such as those described in the application FR2911557.
- the front blocks made according to this known solution certainly make it possible to make the high beam invisible from the outside but at the expense of a reduction of the air-accessible entrance surface through which the air can enter and flow into the vehicle.
- the invention aims to overcome these disadvantages by providing a structural front frame for a motor vehicle.
- This front structural frame comprises an upper longitudinal beam intended to be positioned above a plane defined by the longitudinal members of the vehicle, a lower longitudinal beam and a central part arranged to connect the upper longitudinal beam and the lower longitudinal beam. one to the other, the upper longitudinal beam, the lower longitudinal beam and the central portion defining at least one through opening, the front structural frame comprising shock absorption means adapted to transmit forces under the opening through to the structural framework before.
- the shock absorption means are capable of damping the forces experienced within the through opening towards the front structural frame;
- the shock absorbing means comprise connecting elements of two edges of the front structural frame;
- the connecting elements are chosen alone or in combination from the group consisting of: V-shaped, L-shaped, H-shaped and / or U-shaped, hollow sections with square, rectangular or circular sections, solid sections with square sections, rectangular sections or circular, ropes;
- the connecting elements connect the upper longitudinal beam and the lower longitudinal beam one to the other;
- the shock absorbing means comprise a support for fixing the connecting elements adapted to be fixed to the upper longitudinal beam, the lower longitudinal beam and / or the central portion;
- the connecting elements are made from metal wires or bars or composite rods;
- the central portion is integral with the upper longitudinal beam and / or lower longitudinal beam;
- the upper longitudinal beam and / or the lower longitudinal beam constitute structural inserts of the front structural frame and the central part connects them by a plastic injection method;
- the through opening is of rounded shape, preferably of ob
- FIG. 2 is a diagram illustrating an exploded view of a front structural frame according to a second embodiment of the invention
- the upper longitudinal beam 101 and the lower longitudinal beam 102 are profiles made by pultrusion. These profiles subsequently serve structural inserts during the production of the central portion 103 by a plastic injection process and in which the shock absorbing means 104 comprise connecting elements 105 formed by ropes 105. Ropes 105 connect the upper longitudinal beam 101 and the lower longitudinal beam 102 to each other.
- the upper longitudinal beam 101 and the lower longitudinal beam 102 may for example be stamped metal profiles or extruded profiles. They can also be integral with the central portion 103.
- the connecting elements 105 of the shock absorbing means 104 may also be hollow or solid profiles of various geometric shapes.
- shock function a shock absorber / crash box, absorber for pedestrian shocks (leg shock and hip shock).
- the shock absorption means 104 of the front structural frame 1 comprise ropes 105 connecting the upper longitudinal beam 101 and the lower longitudinal beam 102 to each other. These ropes 105 are distributed in the through opening according to the mesh shown in FIG. 3A and make it possible to transfer the forces undergone within the through opening, for example during an impact with a pedestrian or against a rim, towards the structural frame before 1, through the upper longitudinal beam 101 and the lower longitudinal beam 102.
- FIG. 1 shows a front structural frame 1 according to a first embodiment of the invention, in which the central portion 103 comprises two horizontal beams 106 each extending in an opposite direction of the through opening. These horizontal beams stiffen the central portion 103 without impacting the entrance surface accessible to the air. Such a central portion 103 with two horizontal beams, also shown in Figures 3A-3C and 4, can thus cash out greater efforts. Therefore, a more homogenized transmission, throughout the structural framework before 1, the forces experienced within the through opening is possible. In addition, this extension of the central portion 103 by two horizontal beams 106 is structural because it absorbs the energy of impacts of the barrier-type shock insurance or parking shock.
