一种无缝拼接的折叠屏A seamless splicing folding screen

技术领域technical field

本发明属于显示屏的技术领域，特别涉及可折叠的显示屏。The invention belongs to the technical field of display screens, in particular to foldable display screens.

背景技术Background technique

显示屏是通常意义上是属于电脑的I/O设备，即输入输出设备。它是一种将一定的电子文件通过特定的传输设备显示到屏幕上再反射到人眼的显示工具。目前常用的有LCD显示屏、LED显示屏等等。The display screen is an I/O device that belongs to the computer in the usual sense, that is, an input and output device. It is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye. Currently commonly used are LCD display, LED display and so on.

传统的显示屏均是一体化结构，即通过一个显示界面将所显示的内容显示出来。随着科技的发展和人们生活的需要，慢慢发展出了多界面的拼接显示屏，拼接显示屏通常用于大屏幕播放，但是其体积大，不容易运输。Traditional display screens are all integrated structures, that is, the displayed content is displayed through a display interface. With the development of science and technology and the needs of people's lives, a multi-interface splicing display has been gradually developed. The splicing display is usually used for large-screen playback, but it is bulky and difficult to transport.

于是人们又设计了折叠式的显示屏，如专利申请201620134105.0公开的一种便携式折叠屏，包括不透光的板体，所述板体包括多个折叠段，折叠段之间设有能够使折叠段相互折叠的折叠区域，折叠段上设置有磁块；所述磁块设置在折叠段同侧的端部上，所述折叠段靠近磁块处设有能够使折叠段折弯定型的定型区域。本发明通过折叠结构能够应对不同测量设备遮光及安装需要，而且具有的定型区域能够应对不同调节需要；且结构简单，调节方便，携带方便。Therefore, people have designed a folding display screen, such as a portable folding screen disclosed in patent application 201620134105.0, which includes an opaque board body, and the board body includes a plurality of folding sections. The folding area where the sections are folded with each other, the folding section is provided with a magnetic block; the magnetic block is arranged on the end of the same side of the folding section, and the folding section is provided with a shaping area that can bend and shape the folding section near the magnetic block . The present invention can meet the shading and installation needs of different measuring equipment through the folding structure, and has a shaped area that can meet different adjustment needs; and the structure is simple, easy to adjust, and easy to carry.

然而，上述显示屏之间仅仅是通过磁块吸附进行定型，结构过于简单，使多个折叠段的结合不稳固，容易损坏，且在使用过程中粗糙的磁块吸附结构会导致显示屏拼接不平整，难以达到良好的拼接效果。However, the above-mentioned display screens are only shaped by magnetic block adsorption, and the structure is too simple, which makes the combination of multiple folding sections unstable and easy to damage, and the rough magnetic block adsorption structure during use will lead to poor splicing of the display screens. Flat, it is difficult to achieve a good splicing effect.

又如专利申请201420796566.5公开的一种可折叠屏幕结构，包括第一屏幕和第二屏幕，还包括连接所述第一屏幕和第二屏幕的折叠机构，所述第一屏幕和第二屏幕均包括显示区域和边缘区域，且所述第一屏幕和第二屏幕相互拼接的边缘区域透明；所述折叠机构用于将所述第一屏幕和第二屏幕相互面向叠合或者将所述第一屏幕和第二屏幕相互拼接；所述第一屏幕和第二屏幕相互拼接时，显示区域相互对接，使得边缘区域和显示区域相互交错重叠。还公开一种使用该可折叠屏幕的便携式设备。然而，上述的折叠屏幕由于其第一屏幕和第二屏幕是通过轴结合在一起，轴必然占用空间，导致其打开时，第一屏幕和第二屏幕之间必然存在间隙，而且通过边缘区域和显示区域相互交错重叠使显示屏的显示不完整，影响显示效果，实际上并不能实现无缝对接的效果。Another example is a foldable screen structure disclosed in patent application 201420796566.5, which includes a first screen and a second screen, and also includes a folding mechanism connecting the first screen and the second screen, and the first screen and the second screen both include The display area and the edge area, and the edge area where the first screen and the second screen are joined together are transparent; the folding mechanism is used to face the first screen and the second screen and the second screen are spliced together; when the first screen and the second screen are spliced together, the display areas are butted with each other, so that the edge area and the display area overlap each other. Also disclosed is a portable device using the foldable screen. However, because the first screen and the second screen of the above-mentioned folding screen are combined through the shaft, the shaft must occupy space, so that when it is opened, there must be a gap between the first screen and the second screen, and the edge area and the The interlacing and overlapping of the display areas makes the display of the display screen incomplete and affects the display effect. In fact, the effect of seamless docking cannot be realized.

其它固定板之间的连接结构与固定板5和6之间的是一致的。The connection structure between other fixed plates is consistent with that between the fixed plates 5 and 6 .

结合图3所示，以固定板6为例来说明固定板的结构，对于固定板6来说，其具有顶部61和底部62，顶部61和底部62之间的外端面上设有凹陷部63，所述凹陷部63用以嵌设并固定显示屏1，这样，显示屏1能够被固定板6所保护，同时显示屏1的侧面可以进行无缝对接。3, take the fixed plate 6 as an example to illustrate the structure of the fixed plate, for the fixed plate 6, it has a top 61 and a bottom 62, and the outer end surface between the top 61 and the bottom 62 is provided with a recessed portion 63 , the recessed portion 63 is used to embed and fix the display screen 1, so that the display screen 1 can be protected by the fixing plate 6, and at the same time, the sides of the display screen 1 can be seamlessly connected.

旋转轴8设置于固定板6的顶部61和底部62，使得显示屏1旋转的时候，旋转轴8能够隐身在顶部和底部，不与显示屏占用相同的空间，避免对显示屏的影响及产生拼接间隙，同时，顶部61和底部62均设置有旋转轴8的好处，是可以使显示屏1的旋转控制准确、可靠、稳固，对接时候也平衡，避免显示屏1的上下边拼接不一致的问题。The rotating shaft 8 is arranged on the top 61 and the bottom 62 of the fixed plate 6, so that when the display screen 1 rotates, the rotating shaft 8 can be hidden at the top and bottom, and does not occupy the same space as the display screen, so as to avoid the influence on the display screen and the occurrence of Splicing gap, at the same time, the advantage of having a rotating shaft 8 on both the top 61 and the bottom 62 is that the rotation control of the display screen 1 can be accurate, reliable, and stable, and the docking is also balanced, avoiding the problem of inconsistent splicing of the upper and lower sides of the display screen 1 .

图4为固定板之间结合的原理图，图中仅仅以简略的线条画出固定板的俯视面，突出了固定板之间的结合结构。结合图4所示，两个固定板5、6之间具有旋转轴8，旋转轴8的轴心上设置有导向板81；导向板81呈条状，其中心与旋转轴8的轴心重合，两端对称设置在旋转轴8上，且导向板81的两端分别设置有两个限位开关82、83，其中两个限位开关一个是展开限位开关82，一个是收拢限位开关83，展开限位开关82位于收拢后的固定板外部，收拢限位开关83则位于收拢后的固定板之间，分别控制展开及收拢的固定板5、6位置，以准确控制显示屏的旋转位置。Figure 4 is a schematic diagram of the combination between the fixed plates, in which only the top view of the fixed plates is drawn with simple lines, highlighting the joint structure between the fixed plates. As shown in Fig. 4, there is a rotating shaft 8 between the two fixed plates 5, 6, and a guide plate 81 is arranged on the axis of the rotating shaft 8; , both ends are arranged symmetrically on the rotating shaft 8, and two limit switches 82, 83 are respectively arranged on the two ends of the guide plate 81, wherein one of the two limit switches is the expansion limit switch 82, and the other is the retraction limit switch 83, the expansion limit switch 82 is located outside the folded fixed plate, and the folded limit switch 83 is located between the folded fixed plates, respectively controlling the positions of the expanded and folded fixed plates 5 and 6 to accurately control the rotation of the display screen Location.

导向板81为窄片形的条状结构，很小的空间即可设置，不占用空间，避免固定板5、6之间产生间隙。两个限位开关82、83在旋转平面上以180度布置，可以控制显示屏旋转的准确度；另外还有金属触铁61、51来对应上述两个限位开关(触铁通常采用一个铁片固定在固定板的外表面实现，也可以通过固定板的金属侧壁来实现)，图中所示，在固定板5的外侧表面，靠近旋转轴8的部位设置有金属触铁51，在固定板6的外侧表面，靠近旋转轴8的位置设置有金属触铁61，相邻固定板上设置金属触铁，能够使上述限位开关准确感应固定板的位置，实现准确控制；金属触铁随固定板的旋转在两个限位开关之间摆动，限位开关在金属触铁靠时会发出限位信号，控制系统通过此信号可实现折叠屏旋转角度的控制。The guide plate 81 is a strip structure in the shape of a narrow sheet, which can be installed in a small space without occupying space, and avoids gaps between the fixing plates 5 and 6 . Two limit switches 82, 83 are arranged at 180 degrees on the rotation plane, which can control the accuracy of the display screen rotation; in addition, there are metal contact irons 61, 51 to correspond to the above two limit switches (the contact iron usually adopts an iron The sheet is fixed on the outer surface of the fixed plate, and it can also be realized by the metal side wall of the fixed plate). On the outer surface of the fixed plate 6, a metal contact iron 61 is arranged near the position of the rotating shaft 8, and a metal contact iron 61 is arranged on the adjacent fixed plate, so that the above-mentioned limit switch can accurately sense the position of the fixed plate and realize accurate control; With the rotation of the fixed plate, it swings between the two limit switches. The limit switch will send a limit signal when the metal touches the iron. The control system can realize the control of the rotation angle of the folding screen through this signal.

在结合图1、2所示，通常旋转轴8及导向板81的外部包覆有护套，所述护套用于保护旋转轴及导向板不被外部干扰及破坏。As shown in FIG. 1 and FIG. 2 , usually the outside of the rotating shaft 8 and the guide plate 81 is covered with a sheath, and the sheath is used to protect the rotating shaft and the guide plate from external interference and damage.

A control box can be set on the mobile support, one is to control the folding screen, and the other is to control the display interface of the display screen. The electrical control system is usually set in the control box and can be controlled by the control buttons on the control box.

当操作人员按下展开启动按钮后，各显示屏开始展开，显示屏展开过程中的加速和减速通过内置传感器控制。显示屏展开到位后通过展开限位开关进行定位，满足设备的安全使用要求。When the operator presses the unfolding start button, the display screens start to unfold, and the acceleration and deceleration during the unfolding process of the display screens are controlled by built-in sensors. After the display screen is unfolded in place, it can be positioned by unfolding the limit switch to meet the safety requirements of the equipment.
