本发明涉及柔性屏双折设计技术领域，尤其涉及一种双折连接轴，特指柔性屏内外双折同步转动机构。The invention relates to the technical field of double-fold design of flexible screens, in particular to a double-fold connecting shaft, in particular to a double-fold synchronous rotation mechanism inside and outside the flexible screen.
背景技术Background technique
折叠屏幕，指的是柔性OLED。折叠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，未来折叠屏幕将随着个人智能终端的不断渗透而广泛应用。折叠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，折叠屏幕优势明显，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。Folding screen refers to flexible OLED. The successful mass production of folding screens is not only beneficial to the manufacture of a new generation of high-end smartphones, but also has a profound impact on the application of wearable devices due to its low power consumption and bendability. In the future, folding screens will follow the trend of personal smart phones. Terminal penetration and wide application. Folding screen mobile phone refers to a mobile phone with a bendable and flexible screen. Because it looks like a mans roll, it is also called a mans roll phone. Compared with traditional screens, folding screens have obvious advantages. Not only are they thinner and thinner in size, but they also consume less power than the original devices, which helps to improve the battery life of the device. At the same time, based on its bendable and flexible characteristics, its The durability is also much higher than that of previous screens, reducing the probability of accidental damage to the device.
要实现折叠屏折叠功能，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。考虑到折叠屏的特殊性，传统转轴没有办法满足其功能需求，需要专门的折叠屏转轴来辅助实现，且折叠屏折弯根据应用需求，分为外折及外折两种折弯需求，要进一步实现柔性屏的大尺寸应用，可同时采用两组及两组以上的转动机构来实现多折需求，即同时采用内折及外折的双折功能。In order to realize the folding function of the folding screen, in addition to the screen itself, the design of the connecting components that realize the folding, that is, the connecting shaft at the bending point, is also the biggest technical problem. Considering the particularity of folding screens, traditional hinges cannot meet their functional requirements, and special hinges for folding screens are needed to assist in realization. According to application requirements, folding screens can be divided into two types of bending requirements: outward folding and outward folding. To further realize the large-scale application of flexible screens, two or more sets of rotating mechanisms can be used at the same time to realize the multi-folding requirements, that is, the double-folding functions of internal folding and external folding can be used at the same time.
满足上述功能需求，需要专门的内折及外折转动机构来组合实现。To meet the above functional requirements, a special inward folding and outward folding rotation mechanism is required to realize the combination.
