Problems solved by technology

[0003] The traditional arc-shaped pouch battery directly stamps the formed flat pouch battery, and the flat pouch battery is deformed into an arc-shaped structure through a long stamping time. However, the traditional arc-shaped pouch battery After bending, the aluminum-plastic film packaging sleeve will produce more wrinkles, resulting in poor surface flatness of the curved pouch battery; in addition, although the traditional curved pouch battery has undergone a long press Bending time, but the internal cells of the curved pouch battery still inevitably have rebound stress, which makes the curved pouch battery spontaneously deform from the arc structure to the flat structure, resulting in the arc pouch battery being cycled and stored The arc will change greatly during the process

Embodiment Construction

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention provides an arc-shaped battery shaping structure and an arc-shaped soft package battery. The arc-shaped battery shaping structure comprises an arc-shaped battery cell and a battery cell shaping piece. The arc-shaped battery cell comprises a battery cell body and a first connecting part, and the first connecting part is arranged on the convex arc surface of the battery cell body. The battery cell shaping piece comprises an arc-shaped fixing piece and a second connecting part, the second connecting part is arranged on the concave arc surface of the arc-shaped fixing piece, and the first connecting part is connected with the second connecting part. Due to the fact that the concave cambered surface of the arc-shaped fixing piece abuts against the convex cambered surface of the battery cell body, and the arc-shaped fixing piece has good mechanical strength, the arc-shaped fixing piece can play a role in supporting and fixing the battery cell body, that is, reset deformation of the battery cell body is prevented, and the radian of the arc-shaped battery can be well kept in the transportation and circulation process.

Description

technical field [0001] The invention relates to the field of arc-shaped batteries, in particular to a shape-setting structure of an arc-shaped battery and an arc-shaped pouch battery. Background technique [0002] In order to make the arrangement of various types of electronic components inside the electronic device more compact and to use the space inside the electronic device more effectively, the industry has begun to use various special-shaped secondary batteries including curved batteries. [0003] The traditional arc-shaped pouch battery directly punches the formed flat pouch battery, and the flat pouch battery is deformed into an arc-shaped structure through a long stamping time. However, the traditional arc-shaped pouch battery After bending, the aluminum-plastic film packaging sleeve will produce more wrinkles, resulting in poor surface flatness of the curved pouch battery; in addition, although the traditional curved pouch battery has undergone a long press Bendin...
