Abstract
(EN) The present application provides a battery pack, comprising a housing, a battery cell assembly provided in the housing, a circuit board connected to the battery cell assembly, a wiring harness assembly, and a fixed assembly. The wiring harness assembly has one end welded to the circuit board, and the other end extending out of the housing. The fixed assembly is fixed to the wiring harness assembly and is at least partially provided in a mounting slot of the housing. The fixed assembly comprises a first structural member and a second structural member, the first structural member being fixedly connected to the wiring harness assembly, and the second structural member being detachably connected to the first structural member. The first structural member comprises a first connection part and a first fixed part, the first fixed part being provided in the housing and fixed to the housing. The second structural member is provided with a first accommodation recess, and the first connection part is provided in the first accommodation recess. The battery pack uses a simple insertion mode of the first structural member and the second structural member to simplify a connection structure between the wiring harness assembly and the housing and improve the production efficiency. The present application further provides an electric device provided with the battery pack and a manufacturing method for the battery pack.
(FR) La présente invention concerne un bloc-batterie, comprenant un boîtier, un ensemble élément de batterie disposé dans le boîtier, une carte de circuit imprimé connectée à l'ensemble élément de batterie, un ensemble faisceau de câblage et un ensemble fixe. L'ensemble faisceau de câblage possède une extrémité soudée à la carte de circuit imprimé, et l'autre extrémité s'étend hors du boîtier. L'ensemble fixe est fixé à l'ensemble faisceau de câblage et est au moins partiellement disposé dans une fente de montage du boîtier. L'ensemble fixe comprend un premier élément structural et un second élément structural, le premier élément structural étant connecté à demeure à l'ensemble faisceau de câblage, et le second élément structural étant connecté détachable au premier élément structural. Le premier élément structural comprend une première partie de connexion et une première partie fixe, la première partie fixe étant disposée dans le boîtier et fixée au boîtier. Le second élément structural est pourvu d'un premier évidement de réception, et la première partie de connexion est disposée dans le premier évidement de réception. Le bloc-batterie utilise un mode d'introduction simple du premier élément structural et du second élément structural pour simplifier une structure de connexion entre l'ensemble faisceau de câblage et le boîtier et améliorer l'efficacité de production. La présente invention concerne en outre un dispositif électrique pourvu du bloc-batterie et un procédé de fabrication du bloc-batterie.
