Description
技术领域technical field
本申请涉及显示技术领域,尤其涉及一种柔性屏支撑机构及可卷曲的电子设备。The present application relates to the field of display technology, and in particular, to a flexible screen support mechanism and a rollable electronic device.
背景技术Background technique
对于卷曲的电子设备,柔性屏的支撑机构是其中的关键部分,柔性屏拉出卷筒的部分,需要有不能弯曲的支撑机构对柔性屏进行支撑,以避免柔性屏变形而影响柔性屏的显示和触控;当柔性屏卷入卷筒时,支撑机构又不能影响柔性屏做卷曲动作。For curled electronic devices, the support mechanism of the flexible screen is a key part. The part where the flexible screen pulls out the reel needs to have a support mechanism that cannot be bent to support the flexible screen, so as to avoid the deformation of the flexible screen and affect the display of the flexible screen and touch; when the flexible screen is rolled into the reel, the support mechanism cannot affect the rolling action of the flexible screen.
现有的可卷曲的电子设备多应用于体积较大的电视设备,柔性屏的支撑机构大体有两种方案:一种是采用交叉机构作为柔性屏的支撑机构,当柔性屏拉出卷筒时,柔性屏背面的交叉机构展开,对柔性屏起作用,当柔性屏收纳时,交叉机构合拢,同时显示屏卷曲收纳;另一种是采用垂直链条作为显示屏的支撑机构,链条的转动方向与显示屏的卷曲方向垂直,当柔性屏拉出卷筒时,同时拉出柔性屏上下两端的垂直链条,由于链条的转动方向与柔性屏的卷曲方向垂直,因此链条对柔性屏能起到支撑效果,当柔性屏收纳时,柔性屏与链条分别进行卷曲收纳,两者收纳于不同的位置。The existing rollable electronic devices are mostly used in large-volume TV equipment. There are generally two solutions for the support mechanism of the flexible screen: one is to use a cross mechanism as the support mechanism for the flexible screen. When the flexible screen is pulled out of the reel , the cross mechanism on the back of the flexible screen is unfolded, which acts on the flexible screen. When the flexible screen is stored, the cross mechanism is closed, and the display screen is curled and stored; the other is to use a vertical chain as the support mechanism of the display screen. The curling direction of the display screen is vertical. When the flexible screen is pulled out of the reel, the vertical chains at the upper and lower ends of the flexible screen are pulled out at the same time. Since the rotation direction of the chain is perpendicular to the curling direction of the flexible screen, the chain can support the flexible screen. , When the flexible screen is stored, the flexible screen and the chain are respectively curled and stored, and the two are stored in different positions.
以上两种柔性屏支撑机构,机构尺寸较大,结构复杂,且柔性屏支撑机构与显示屏分开设置,当柔性屏卷曲时,柔性屏与柔性屏支撑机构分别收纳于不同的位置,导致收纳装置尺寸较大,因此现有的方案不适用于便携的卷曲设备。The above two flexible screen support mechanisms have large size and complex structure, and the flexible screen support mechanism and the display screen are arranged separately. When the flexible screen is curled, the flexible screen and the flexible screen support mechanism are respectively accommodated in different positions, resulting in the storage device. The size is large, so the existing solutions are not suitable for portable crimping equipment.
