Abstract
(EN)
A battery module. The battery module comprises: a plurality of batteries (1) arranged along a length direction (L); an end plate (2) disposed at the end of the length direction (L) of the plurality of batteries (1); FPCs (3), the FPCs (3) comprising main body parts (31) and bending parts (32), the main body parts (31) being disposed along a height direction (H) on the corresponding batteries (1) and being electrically connected with the corresponding batteries (1), the bending parts (32) bending and extending from the main body parts (31) and being located at the lower sides of the main body parts (31), and the bending parts (32) being fixedly connected to the end plate (2); and connectors (4) fixedly connected to the bending parts (32) of the FPCs (3) and electrically connected with the FPCs (3). In the battery module, the connectors (4) are fixedly connected to bending parts (32) of the FPCs (3) and the bending parts (32) are fixedly connected to the end plate (2), so that the connectors (4) are fixed to the end plate (2) by mean of the FPCs (3) and thus when the connectors (4) are impacted by vibration, the flexibility characteristic of the FPCs (3) can be used to transmit and release the impact.

La présente invention porte sur un module de batterie comprenant : une pluralité de batteries (1) agencées dans une direction de longueur (L) ; une plaque d'extrémité (2) placée à l'extrémité de la direction de longueur (L) de la pluralité de batteries (1) ; des FPC (3), comprenant des parties de corps principal (31) et des parties de courbure (32), les parties de corps principal (31) étant placées dans une direction de hauteur (H) sur les batteries correspondantes (1) et étant électriquement connectées aux batteries correspondantes (1), les parties de courbure (32) se courbant et s'étendant à partir des parties de corps principal (31) et étant situées sur les côtés inférieurs des parties de corps principal (31), et les parties de courbure (32) étant reliées à demeure à la plaque d'extrémité (2) ; et des connecteurs (4) reliés à demeure aux parties de courbure (32) des FPC (3) et connectés électriquement aux FPC (3). Dans le module de batterie, les connecteurs (4) sont reliés à demeure à des parties de courbure (32) des FPC (3) et les parties de courbure (32) sont reliées à demeure à la plaque d'extrémité (2), de telle sorte que les connecteurs (4) sont fixés à la plaque d'extrémité (2) au moyen des FPC (3) et, par conséquent, lorsque les connecteurs (4) subissent un choc par vibration, la caractéristique de flexibilité des FPC (3) peut permettre de transmettre et relâcher le choc.
