Abstract
(EN) Embodiments of the present application provide a sleeve assembly, a cover plate assembly, a battery, and an electrical device. The sleeve assembly is used for sealing a through hole, and comprises: a sleeve having at least one end provided with an opening; and a rivet body comprising a body portion. The dimension of the body portion is greater than the diameter dimension of the sleeve. The body portion is used for, after the sleeve is inserted into the through hole along the axial direction, being capable of being inserted into the sleeve by means of the opening and squeezing the inner wall of the sleeve, so as to form, on the outer wall of the sleeve, protrusions used for riveting the sleeve to the through hole. When the sleeve assembly in the embodiments of the present application is used to seal the through hole, it is only necessary to sequentially insert the sleeve into the through hole and insert the body portion into the sleeve to rivet the sleeve assembly to the through hole, so as to complete sealing of the through hole. The sealing process of the through hole can be simplified, and the sealing efficiency of the through hole is improved. Moreover, the debris is not easy to produce during the sealing process, which improves the safety sealing performance.
(FR) Selon des modes de réalisation, la présente invention concerne un ensemble manchon, un ensemble plaque de couvercle, une batterie et un dispositif électrique. L'ensemble manchon permet de sceller un trou traversant, et comprend : un manchon présentant au moins une extrémité pourvue d'une ouverture ; et un corps de rivet comprenant une partie corps. La dimension de la partie corps est supérieure à la dimension de diamètre du manchon. La partie corps est utilisée pour, après que le manchon est inséré dans le trou traversant le long de la direction axiale, pouvoir être insérée dans le manchon au moyen de l'ouverture et presser la paroi interne du manchon, de manière à former, sur la paroi externe du manchon, des saillies permettant de riveter le manchon au trou traversant. Dans les modes de réalisation de la présente invention, lorsque l'ensemble manchon est utilisé pour sceller le trou traversant, il est uniquement nécessaire de séquentiellement insérer le manchon dans le trou traversant et d'insérer la partie corps dans le manchon pour riveter l'ensemble manchon au trou traversant, de manière à sceller le trou traversant. Le processus de scellement du trou traversant peut être simplifié, et l'efficacité de scellement du trou traversant est améliorée. De plus, les débris ne sont pas faciles à produire lors du processus de scellement, ce qui améliore les performances de scellement de sécurité.
(ZH) 本申请实施例提供一种套筒组件、盖板组件、电池及用电装置,套筒组件用于密封通孔,套筒组件包括:套筒,至少一端具有开口;钉体,包括本体部,本体部尺寸大于套筒的筒径尺寸,本体部用于在套筒沿轴向插入通孔后,能由开口插入套筒并挤压套筒内壁,以在套筒外壁形成用于将套筒铆接于通孔的凸起。在使用本申请实施例的套筒组件密封通孔时,只需依次将套筒插入通孔,本体部插入套筒即可将套筒组件铆接于通孔,完成通孔的密封。能够简化通孔的密封工序,提高通孔的密封效率。且在密封过程中不易产生碎屑,提高密封的安全性能。
