Title
(EN) BATTERY MODULE

Abstract
(EN)
A battery module. The battery module comprises: a plurality of batteries (1) sequentially arranged along the length direction; a cushion pad (2) provided between every two adjacent batteries (1) along the length direction (L), the cushion pad (2) comprising a main body portion (21); and extension portions (22) extending outwards from end surfaces (211) of the main body portion (21) along the height direction (H), each extension portion (22) comprising a concave portion (221) and convex portions (222), wherein the convex portions (222) are located on the two sides of the extension portion (22) in the width direction (W) and protrude outwards, and the concave portion (221) is located between the convex portions (222) in the width direction (W) and concaves inwards relative to the convex portions (222). When the cushion pad (2) is subjected to an extrusion force along the length direction (L), the extrusion force on the cushion pad (2) is concentrated to the concave portions (221) and the convex portions (222) of the extension portions (22); the concave portions (221) of the extension portions (22) are stressed to deform and protrude outwards, and the deformation of the convex portions (222) located on the two sides of the concave portions (221) along the width direction (W) due to extrusion of the concave portions is larger than the deformation of the entire cushion pad (2) along the height direction (H) due to extrusion, thereby ensuring that the cushion pad (2) does not exceed the corresponding surface of the battery (1) along the height direction (H), and then the flatness of the corresponding surface of the battery (1) along the height direction (H) is not affected.

L'invention concerne un module de batterie. Le module de batterie comprend : une pluralité de batteries (1) agencées séquentiellement le long de la direction de la longueur ; un coussinet d'amortissement (2) disposé entre chaque paire de batteries adjacentes (1) le long de la direction de la longueur (L), le coussinet d'amortissement (2) comprenant une partie de corps principal (21) ; et des parties d'extension (22) s'étendant vers l'extérieur à partir de surfaces d'extrémité (211) de la partie de corps principal (21) le long de la direction de la hauteur (H), chaque partie d'extension (22) comprenant une partie concave (221) et des parties convexes (222), les parties convexes (222) étant situées sur les deux côtés de la partie d'extension (22) dans la direction de la largeur (W) et font saillie vers l'extérieur, et la partie concave (221) est située entre les parties convexes (222) dans la direction de la largeur (W) et est concave vers l'intérieur par rapport aux parties convexes (222). Lorsque le coussinet d'amortissement (2) est soumis à une force d'extrusion le long de la direction de la longueur (L), la force d'extrusion sur le coussinet d'amortissement (2) est concentrée sur les parties concaves (221) et les parties convexes (222) des parties d'extension (22) ; les parties concaves (221) des parties d'extension (22) sont sollicitées pour se déformer et faire saillie vers l'extérieur, et la déformation des parties convexes (222) situées sur les deux côtés des parties concaves (221) le long de la direction de la largeur (W) en raison de l'extrusion des parties concaves est plus grande que la déformation de la totalité du coussinet d'amortissement (2) le long de la direction de la hauteur (H) due à l'extrusion, garantissant ainsi que le coussinet d'amortissement (2) ne dépasse pas la surface correspondante de la batterie (1) le long de la direction de la hauteur (H), puis la planéité de la surface correspondante de la batterie (1) le long de la direction de la hauteur (H) n'est pas affectée.

一种电池模组,其包括:多个电池(1),沿长度方向依次排列;缓冲垫(2),沿长度方向(L)设置于相邻两个电池(1)之间;缓冲垫(2)包括:主体部(21);延伸部(22),从主体部(21)沿高度方向(H)的端面(221)向外延伸出,延伸部(22)包括凹部(221)以及凸部(222),凸部(222)沿宽度方向(W)位于延伸部(22)的两侧且向外突出,凹部(221)沿宽度方向(W)位于凸部(222)之间且相对凸部(222)向内凹入。缓冲垫(2)受到沿长度方向(L)的挤压力时,缓冲垫(2)受到的挤压力集中到延伸部(22)的凹部(221)和凸部(222),延伸部的凹部(221)受力变形而向外突出,位于凹部(221)两侧的凸部(222)受凹部挤压沿宽度方向(W)的变形大于缓冲垫(2)整体受挤压沿高度方向(H)的变形,保证缓冲垫(2)不会超出电池(1)沿高度方向(H)的对应表面,进而不会影响电池(1)沿高度方向(H)的对应表面的平整性。
