Document Type and Number:
WIPO Patent Application WO/2023/159642
Kind Code:
A1
Abstract:
Provided in the present application are a riveted assembly, a battery, an electric device, and an assembly method and apparatus for a riveted assembly. The present application relates to the technical field of batteries. The riveted assembly comprises a first member, a second member and a rivet member, wherein the first member is provided with a first connecting portion; the second member is provided with a first hollow portion, and has a first wall and a second wall which are arranged opposite each other; a rivet body of the rivet member is configured to sequentially pass through the first wall, the first hollow portion, the second wall and the first connecting portion; and in an axial direction of the rivet body, the rivet body is provided with a first weak portion and a first limiting portion, which are spaced apart from each other. The first weak portion protrudes in a radial direction of the rivet body when the rivet body is axially stressed to form a second limiting portion, so that the first connecting portion and the second wall are connected between the first limiting portion and the second limiting portion so as to lock the second wall and the first connecting portion to reduce the risk of the first member and the second member shaking relative to each other, thereby improving the connection stability between the first member and the second member.
