Description

全贴合应用的两轴外折下部齿条转动机构 技术领域
本发明涉及柔性屏应用技术领域，尤其涉及一种柔性屏应用的连接轴，特指一种全贴合应用的两轴外折下部齿条转动机构。
背景技术
柔性屏幕，指的是柔性OLED。柔性屏幕的成功量产不仅重大利好于新一代高端智能手机的制造，也因其低功耗、可弯曲的特性对可穿戴式设备的应用带来深远的影响，未来柔性屏幕将随着个人智能终端的不断渗透而广泛应用。柔性屏手机是指采用可弯曲、柔韧性佳屏幕的手机，因为形似芒卷，又被称为卷芒手机。相较于传统屏幕，柔性屏幕优势明显，不仅在体积上更加轻薄，功耗上也低于原有器件，有助于提升设备的续航能力，同时基于其可弯曲、柔韧性佳的特性，其耐用程度也大大高于以往屏幕，降低设备意外损伤的概率。
要实现柔性屏折叠功能，除了屏幕本身之外，实现折叠的连接组件，即折弯处的连接轴设计亦是最大的技术难题。当屏幕本身安装上转动组件之后，由于屏与机械组件中间的镂空，没有填充物遮挡，当屏幕点亮以后会出现影射的条纹，在使用的时候体验感会变差，而且转动组件零配件过多的问题也会给产品本身带来成本增加、制造繁琐等问题。
