Battery holder and manufacturing process of said battery holder

A manufacturing process of a battery holder (1) for a transport vehicle comprising the following steps:

• providing (E1) an initial main profile (11i) extending between a first end (13) and a second end (15);
• providing (E2) a closing element (31) extending between a primary end portion (33) and a secondary end portion (35), the closing element (31) presenting externally, a cooperation surface (37);
• bending (E3) the initial main profile (11i) according to a bending curve so as to form a main profile (11) extending along the bending curve between the first end (13) and the second end (15), the main profile (11) having a first curved portion (14) disposed between the first end (13) and the second end (15);
• assembling (E5) a frame (3) having a closed shape by securing the first end (13) of the main profile (11) to the primary end portion (33) of the closing element (31), when the first end (13) of the main profile (11) is leaning on the cooperation surface (37) at the level of the primary end portion (33) so as to form a first corner (6) of the closed shape;
• and by securing the second end (15) of the main profile (11) to the secondary end portion (35) of the closing element (31), when the second end (15) of the main profile (11) is leaning on the cooperation surface (37) at the level of the secondary end portion (35) so as to form a second corner (8) of the closed shape, the arrangement constituted by the main profile (11) and the closing element (31) assembled together forming said closed shape comprising the first corner (6) and the second corner (8);
• assembling (E8) the battery holder (1) by securing a floor (5) and the frame (3), the battery holder (1) in which the closed shape of the frame (3) is connected to the floor (5) and in which the frame (3) and the floor (5) are delimiting between them a housing (4) intended to receive all or part of a battery.
