The invention concerns a battery holder (1) for a transport vehicle, the battery holder (1) comprising the successive stacking in this order of: a floor (5), at least two frames (3) and a lid (2); the floor (5), the at least two frames (3) and the lid (2) delimiting between them a housing (4) intended to receive battery modules (7) ; each frame (3) of the at least two frames (3) being fixedly attached to each adjacent frame (3) by a structural adhesive (9), said structural adhesive (9) being interposed between two adjacent frames (3) and configured to ensure mechanical fastening between said frames (3).The invention also concerns a battery (100) comprising such a battery holder (1).

L'invention concerne un plancher (30), en particulier de véhicules industriels, comprenant une tôle relief (10) présentant sur sa face supérieure (11) une pluralité de motifs en relief, chaque motif en relief comprenant une ou plusieurs parties saillantes (20), lesdits motifs en relief étant disposés de façon périodique, discrète et ordonnée, la hauteur h desdits motifs en reliefs étant comprise entre 0,3 et 3 mm et sur sa face inférieure (12) une surface brute de laminage avec une rugosité R<max> inférieure à 8 µm, un support en bois (30) caractérisé en ce que la face inférieure de la tôle relief est collée sur le support en bois avec une colle bi-composant sans cuisson (31) comprenant un composant de résine comprenant au moins une résine époxyde et un composant d'agent de durcissement, et son procédé de fabrication. L'utilisation d'un plancher selon l'invention, dans un véhicule industriel, de préférence un véhicule frigorifique, est avantageuse.

The invention concerns an assembly (1) for battery holder comprising a first structural element (10) presenting a first contact surface (s10); a second structural element (30) presenting a second contact surface (s30) in direct contact with the first contact surface (s10); at least one mechanical fastener (50) securing the first structural element (10) with the second structural element (30); and an sealing agent (70) disposed inside a groove (20) defined between the second structural element (30) and the first structural element (10).The invention also concerns an assembling method for assembling such an assembly (1) and a battery holder for a transport vehicle comprising such an assembly (1).

The invention concerns an extruded profile made of an Al-Mg-Si aluminium alloy designed for industrial automotive applications. extruded profile comprising an Al-Mg-Si alloy containing, in wt.%, Si 0.3 - 1.2, Mg 0.3-1.1, Cu ≤ 0.85, Mn 0.05 - 0.80, Cr 0.01 - 0.20, Fe 0.26 - 0.64, preferably Fe 0.30 - 0.60, Zn 0.15 - 1.0, V ≤ 0.10, Ti ≤ 0.10, Zr ≤ 0.15, other elements < 0.05 each and < 0.15 total, rest aluminium, wherein Free-Si ≥ 0.50 with Free-Si = Si - 0,3 * (Fe + Mn), wherein Si, Fe, and Mn represent the silicon, iron, and manganese content in wt.%. The invention also relates to the manufacturing process to obtain such extruded profile.

The invention relates to a crash management system (100) for a motor vehicle having a crossbeam (10) which extends substantially along a transverse direction (Y), wherein the crossbeam (10) has two crash boxes (24, 26) arranged at a distance from one another, wherein the crossbeam (10) can be fastened to a vehicle structure, and wherein the crossbeam (10) has a closed cross-section having a front belt (12), a rear belt (14) and two transverse walls (16, 18) connecting the front belt (12) with the rear belt (14).

The invention concerns a manufacturing method for producing a structural component (1) for a vehicle, comprising a providing step (E1) in which a first profile (10) and at least one second profile (20) are provided ; an assembly step (E2) in which the first profile (10) and the second profile (20) are arranged in an assembly configuration (AC) wherein the first profile (10) and the second profile (20) are movable relative to each other according to at least one degree of freedom; and a fixing step (E3) in which a fixing element (30) secure the first profile (10) with the second profile (20) by removing said degree of freedom.The invention also concerns a structural component (1), and a sill or a battery holder comprising such structural component (1).
