(EN) TOP COVER ASSEMBLY FOR BATTERY, BATTERY, AND DEVICE USING BATTERY AS POWER SUPPLY
(FR) ENSEMBLE COUVERCLE SUPÉRIEUR POUR BATTERIE, BATTERIE, ET DISPOSITIF UTILISANT UNE BATTERIE EN TANT QU'ALIMENTATION ÉLECTRIQUE
Abstract
(EN) The present disclosure provides a top cover assembly for a battery, a battery and a device using a battery as a power source. The top cover assembly includes: a cover plate body having a liquid injection hole; a mounting part configured to be connected with the cover plate body and arranged around the liquid injection hole; a sealing element configured to be connected with the mounting part, wherein the sealing element includes a first top wall and a first side wall connected to the periphery of the first top wall, the first top wall is configured to cover the liquid injection hole, and the first side wall is configured to be in press fit with the mounting part to achieve sealing of the liquid injection hole; and a fixing element configured to be connected with the cover plate body and to fix the sealing element to the mounting part.
(FR) La présente divulgation concerne un ensemble couvercle supérieur pour une batterie, une batterie, et un dispositif utilisant une batterie en tant qu'alimentation électrique. L'ensemble couvercle supérieur comprend : un corps de plaque de couvercle ayant un trou d'injection d'électrolyte ; une partie de montage utilisée pour être reliée au corps de plaque de couvercle et disposée autour du trou d'injection d'électrolyte ; un élément d'étanchéité utilisé pour être relié à la partie de montage, l'élément d'étanchéité comprenant une première paroi supérieure et une première paroi latérale reliée à la périphérie extérieure de la première paroi supérieure, la première paroi supérieure étant utilisée pour recouvrir le trou d'injection d'électrolyte, et la première paroi latérale étant utilisée pour venir en prise avec la partie de montage en butée pour sceller le trou d'injection d'électrolyte ; et un élément de fixation utilisé pour être relié au corps de plaque de couvercle et fixer l'élément d'étanchéité à la partie de montage.
