Abstract
(EN)
A battery box, comprising: a heat exchange plate (1); a lower frame body (2), located on the heat exchange plate (1), the lower frame body (2) and the heat exchange plate (1) together forming an accommodating space having an upward opening and used for accommodating batteries (51), the heat exchange plate (1) being used for supporting the batteries (51) and exchanging heat with the batteries (51), and the lower frame body (2) being a hollow structure having a hollow cavity (S); a protective plate (3), located below the heat exchange plate (1) and protecting the heat exchange plate (1) from below; and a self-sealing riveting element (4), fixing the protective plate (3), the heat exchange plate (1), and the lower frame body (2) together. The self-sealing riveting element (4) penetrates through the protective plate (3) and the heat exchange plate (1) in a vertical direction (Z), the self-sealing riveting element (4) is inserted into the lower frame body (2) and at least partially exposed from the lower frame body (2); the self-sealing riveting element (4) is sealed at a first position (P1) where the self-sealing riveting element (4) penetrates through the protective plate (3), and the self-sealing riveting element (4) is sealed at a second position (P2) where the self-sealing riveting element (4) is inserted into the lower frame body (2). The self-sealing riveting element (4) can be directly sealed at the first position (P1) where the self-sealing riveting element (4) penetrates through the protective plate (3) and the second position (P2) where the self-sealing riveting element (4) is inserted into the lower frame body (2), thereby solving the sealing problem of a conventional fastener, simplifying the assembling process, and reducing costs.

L'invention concerne un boîtier de batterie, comprenant : une plaque d'échange de chaleur (1); un corps de cadre inférieur (2), situé sur la plaque d'échange de chaleur (1), le corps de cadre inférieur (2) et la plaque d'échange de chaleur (1) formant ensemble un espace de logement ayant une ouverture vers le haut et utilisé pour recevoir des batteries (51), la plaque d'échange de chaleur (1) étant utilisée pour supporter les batteries (51) et échanger de la chaleur avec les batteries (51), et le corps de cadre inférieur (2) étant une structure creuse comportant une cavité creuse (S); une plaque de protection (3), située sous la plaque d'échange de chaleur (1) et protégeant la plaque d'échange de chaleur (1) par en dessous; et un élément de rivetage auto-obturant (4), fixant la plaque de protection (3), la plaque d'échange de chaleur (1) et le corps de cadre inférieur (2) ensemble. L'élément de rivetage auto-obturant (4) pénètre à travers la plaque de protection (3) et la plaque d'échange de chaleur (1) dans le sens vertical (Z), l'élément de rivetage auto-obturant (4) est inséré dans le corps de cadre inférieur (2) et est au moins partiellement exposé depuis le corps de cadre inférieur (2); l'élément de rivetage auto-obturant (4) est scellé à une première position (P1) où l'élément de rivetage auto-obturant (4) pénètre à travers la plaque de protection (3), et l'élément de rivetage auto-obturant (4) est scellé à une seconde position (P2) où l'élément de rivetage auto-obturant (4) est inséré dans le corps de cadre inférieur (2). L'élément de rivetage auto-obturant (4) peut être directement scellé au niveau de la première position (P1) où l'élément de rivetage auto-obturant (4) pénètre à travers la plaque de protection (3) et la seconde position (P2) où l'élément de rivetage auto-obturant (4) est inséré dans le corps de cadre inférieur (2), ce qui permet de résoudre le problème d'étanchéité d'un dispositif de fixation classique, de simplifier le processus d'assemblage et de réduire les coûts.
