Problems solved by technology

[0002] Most of the foldable shaft structures of commercially available foldable mobile phones are traditional structures. In this traditional structure, one end of the flexible circuit board FPC from the host is fixedly connected with the host, and the other end is fixedly connected with the flip cover. The FPC must pass through the The rotating shaft hole on the host, because the FPC cannot be fixedly connected with the rotating shaft hole under this structural state, so when the FPC rotates with the flip cover, the FPC will rub against the rotating shaft hole, and at the same time, the FPC and the flip cover are not completely fixed. There will be friction, and when the flip cover rotates, the FPC will not only produce bending deformation, but also twist and deform, so the FPC can only be made narrower, otherwise it will hinder the distortion and deformation, and also reduce the gap with the shaft hole of the host. Increase the friction; in addition, there is a lateral movement of the FPC when it is twisted and deformed, so a large gap must be left between the FPC and the host

Embodiment Construction

[0007] specific implementation plan

[0008] attached figure 1 A schematic diagram is given to understand the connection relationship between the host 1 , flip cover 2 and the flexible circuit board FPC in the prior art. The host and the flip cover are connected by means of the rotating shaft 3; the FPC is divided into three sections, which are directly fixed on the host with the connecting section 41 of the host, and fixed on the flip with the connecting section 42 of the flip cover, and the middle section passes through the shaft hole section 43 and is suspended in the shaft hole Therefore, during the rotation of the flip cover, the axial series movement and twisting deformation of the FPC will inevitably occur, and friction will occur with the host and the flip cover. The wear and tear caused by long-term use will seriously affect the performance of the whole machine.

Abstract

A rotating axle of a folded mobile phone includes a host a turnover cover connecting with the host by the axle, electric connection is realized by a flexible PC (FPC) through the axle hole between the host and the turnover cover, an axle sleeve containing the FPC is set in the holes. The FPC is fixedly connected with the sleeve which is fixedly connected with the turnover axle hole, the sleeve is connected dynamically with the host. This invention fixes the FPC, the sleeve and turnover cover together, or makes the sleeve and the turnover as one unit, friction will not occur between the host and turnover and only curvature but not tortion may happen there is no gap between FPC and the sleeve hole, so the width of FPC can be increased.

Description

technical field [0001] The invention relates to a foldable mobile phone, in particular to a structure between a rotating shaft and a flexible circuit board FPC in a foldable mobile phone. Background technique [0002] Most of the foldable shaft structures of commercially available foldable mobile phones are traditional structures. In this traditional structure, one end of the flexible circuit board FPC from the host is fixedly connected with the host, and the other end is fixedly connected with the flip cover. The FPC must pass through the The rotating shaft hole on the host, because the FPC cannot be fixedly connected with the rotating shaft hole under this structural state, so when the FPC rotates with the flip cover, the FPC will rub against the rotating shaft hole, and at the same time, the FPC and the flip cover are not completely fixed. There will be friction, and when the flip cover rotates, the FPC will not only produce bending deformation, but also twist and deform,...
