    摘要： This application discloses a battery box, a battery, and an electric device, and relates to the field of battery technologies. The battery box includes an upper cover. The upper cover includes an upper cover body and a pressing strip. A circumferential edge of the upper cover body is provided with a flange. The flange has a first surface. The first surface is a surface of the flange facing away from a lower box body of the battery box. The pressing strip is in attachment connection with the first surface of the flange. The pressing strip is in attachment connection with the flange of the upper cover body to form the upper cover, such that the pressing strip can not only reinforce the flange of the upper cover body and prevent deformation thereof, but also allow the upper cover to be integrated for provision, eliminating the procedure of assembling the upper cover body and the pressing strip in the factory. This effectively improves the overall assembly efficiency of the battery box and the battery, facilitating automatic assembly.

    摘要： The present application discloses a battery cell, a battery and an electrical device. The battery cell comprises an electrode assembly, a shell, a pressure relief mechanism and a support plate, wherein the shell is used for accommodating the electrode assembly and comprises a first side plate; the pressure relief mechanism is arranged on the first side plate and is configured to be actuated when the internal pressure of the battery cell reaches a first threshold, so as to release the internal pressure; the support plate is arranged between the first side plate and the electrode assembly; the support plate is provided with a weak portion which is opposite to the pressure relief mechanism in the thickness direction of the first side plate; the shape of the weak portion is the same as that of the outline of the pressure relief mechanism, and the external dimension of the weak portion is not greater than the dimension of the outline of the pressure relief mechanism; the support plate is configured to rupture along the weak portion when the internal pressure of the battery cell reaches a second threshold, so as to form a channel for guiding fluid to the pressure relief mechanism. The technical solutions in the embodiments of the present application can effectively improve the safety of battery cells.

    摘要： This application discloses an electronic device. The electronic device includes a battery cover and a camera assembly. Amounting hole is arranged on the battery cover, and the camera assembly is mounted in the mounting hole. The battery cover includes a first cover layer and a second cover layer that are arranged in a stacked manner, and the first cover layer is located on an outer side of the second cover layer, where the first cover layer is made of a polyurethane material, and the second cover layer is made of a glass fiber material. The camera assembly includes a decoration member, the decoration member includes a first decoration portion and a second decoration portion, the first decoration portion is located on an outer side of the battery cover and is adhered to the second cover layer, and the second decoration portion is located on an inner side of the battery cover and is adhered to the second cover layer, where the first decoration portion partially covers the first cover layer. In this application, the first decoration portion and the second decoration portion are adhered to an inner side and an outer side of the second cover layer respectively, thereby improving connection sealing performance and adhesive waterproof performance of the battery cover and the decoration member. In addition, because the first decoration portion partially covers the first cover layer, there is no need to use a decoration ring, thereby reducing a cost.
