Description

一种对准结构和包括对准结构的COB无缝拼接显示系统
本申请要求于2020年04月26日提交中国专利局、申请号为202010340494.3、发明名称为“一种对准结构和包括对准结构的COB无缝拼接显示系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及COB显示产品拼接技术领域，更具体地，涉及一种对准结构和包括对准结构的COB无缝拼接显示系统。
背景技术
LED显示屏连接是目前拓展显示屏面积的主流方法，虽然LED显示屏模组之间存在窄边的连接缝，但相对于整体连接面积来说在视觉上可以忽略不计。现有的运用COB技术进行封装的LED显示屏模组在安装过程中需要借助导向结构来实现，导向结构虽然可以实现定位功能，但是同样限制了LED显示屏模组的浮动，从而无法调节模组之间的间隙，影响显示效果；而且系统规模越大，显示效果受到的影响会越严重。
例如，中国授权公告号为CN205388878U，专利名称为一种LED显示屏连接结构中公开了：“一种LED显示屏连接结构，包括LED显示屏和连接装置，所述LED显示屏背面的脚点上固定有卡扣，且所述LED显示屏的拐角设有螺纹孔，所述连接装置上设有安装槽，所述安装槽与卡扣卡接，所述连接装置的中心上设有固定孔，所述固定孔通过螺栓与螺纹孔固定连接，所述LED显示屏通过安装槽和卡扣与连接装置固定连接，且LED显示屏通过螺栓、固定孔和螺纹孔与连接装置固定连接。”虽然该LED显示屏连接结构通过安装槽和卡扣与连接装置固定连接，结构简单，安装使用方便，但是LED显示屏之间的间隙无法调节，从而影响显示效果，而且LED显示屏连接结构越大，显示效果受到的影响会越严重。
发明内容
本发明旨在克服上述现有技术中存在的模组之间的间隙无法调节的问题，提供一种能同时定位和进行间隙调节的对准结构和包括对准结构的COB无缝拼接显示系统。
本发明采取的技术方案是，提供一种对准结构和COB无缝拼接显示系统，
其中，对准结构包括第一连接件、第二连接件、转接座和导向件，第一连接件和第二连接件相对设置，转接座设置在第一连接件上且开设有导向孔，转接座和第二连接件之间设置有间隙配合的两个连接单元。导向件包括导向部和固定部，固定部一端固定设置在第二连接件上，固定部另一端与导向部连接，导向部与导向孔位置相对。第一连接件与第二连接件初始连接状态下，导向部插入导向孔中，从而两个连接单元连接在一起；第一连接件与第二连接件完全连接状态下，固定部位于导向孔中，且固定部与导向孔的孔壁之间的间隙大于或等于两个连接单元之间的间隙。
第一连接件和第二连接件刚开始靠近时，因为导向部与导向孔位置相对，所以导向部会插入到导向孔中，此时导向部和导向孔配合即可起到导向定位作用，使得两个连接单元连接在一起；当第一连接件和第二连接件进一步靠近时，导向部从导向孔中穿出，固定部进入到导向孔内，因为固定部与导向孔的孔壁之间的间隙大于或等于两个连接单元之间的间隙，使得其中一个连接单元可相对另一个连接单元在其间隙范围内调节位置，从而第二连接件可相对第一连接件进行适当的位置调整，最终实现既可以导向定位又可以进行位置调节的双重目的，适用性强。
另外，一种COB无缝拼接显示系统包括至少两个对准结构，第一连接件为箱体，箱体之间一体成型；第二连接件为模组，模组之间相互拼接在一起。
将对准结构应用到COB无缝拼接显示系统中，当模组固定到箱体上以后，模组之间还可以进行位置调整，从而能够很好的消除模组之间的间隙，大大增强该显示产品的整体显示效果。
与现有技术相比，本发明的有益效果为：
1.本发明的对准结构不仅在第一连接件和第二连接件连接过程中实现了导向定位作用，而且第二连接件还能相对第一连接件进行适当的位置调整，适用性大大增强。
2.本发明的COB无缝拼接显示系统能够很好的消除模组之间的间隙，从而大大增强了该显示产品的整体显示效果。

具体实施方式
本发明附图仅用于示例性说明，不能理解为对本发明的限制。为了更好说明以下实施例，附图某些部件会有省略、放大或缩小，并不代表实际产品的尺寸；对于本领域技术人员来说，附图中某些公知结构及其说明可能省略是可以理解的。
实施例1
参考图1-图4，对准结构包括第一连接件1、第二连接件2、转接座3和导向件4，第一连接件1和第二连接件2相对设置，转接座3设置在第一连接件1上且开设有导向孔31，转接座3和第二连接件2之间设置有间 隙配合的两个连接单元(即第一连接件1和第二连接件2通过两个连接单元连接在一起，且两个连接单元在连接处具有间隙)。导向件4包括导向部41和固定部42，固定部42一端固定设置在第二连接件2上，固定部42另一端与导向部41连接，导向部41与导向孔31位置相对(导向部41与导向孔31配合就可以起到导向定位作用)。第一连接件1与第二连接件2初始连接状态下，导向部41插入导向孔31中，在导向部41和导向孔31的导向作用下，两个连接单元连接在一起，这里不对导向部41和导向孔31的孔壁之间的间隙大小作具体限定，只要满足导向部41和导向孔31插接在一起时两个连接单元能够连接在一起即可；第一连接件1与第二连接件2完全连接状态下，固定部42位于导向孔31中，且固定部42与导向孔31的孔壁之间的间隙大于或等于两个连接单元之间的间隙，因为固定部42与导向孔31的孔壁之间的间隙大于或等于两个连接单元之间的间隙，这样第二连接单元就可以相对第一连接单元作两个连接单元之间间隙大小内的位置调整。
工作原理：第一连接件1和第二连接件2刚开始靠近时，因为导向部41与导向孔31位置相对，所以导向部41会插入到导向孔31中，此时导向部41和导向孔31插接配合即可起到导向定位作用，使得两个连接单元连接在一起；当第一连接件1和第二连接件2进一步靠近时，导向部41从导向孔31中穿出，固定部42进入到导向孔31内，因为固定部42与导向孔31的孔壁之间的间隙大于或等于两个连接单元之间的间隙，使得其中一个连接单元可相对另一个连接单元在其间隙范围内调节位置，从而第二连接件2可相对第一连接件1进行适当的位置调整，最终实现既可以导向定位又可以进行位置调节的双重目的，适用性强。
参考图3和图4，为了更好的实现导向定位效果，将导向部41设置为具有导向斜面，但不局限于此，在其它实施例中，导向部41的导向面还可以是弧面等，在此不再详述。
参考图2，为了进一步增强导向定位效果，将导向件4数量设置为四个，并且环绕转接座3的几何中心设置，转接座3上开设有与四个导向件 4一一对应的四个导向孔31。但不局限于此，在其它实施例中，导向件4的数量还可以是1个、2个或3个等，导向件4的数量和具体位置均可以根据实际需求来定，在此不再详述。
参考图3和图4，导向件4还包括阻挡部43，阻挡部43两端分别连接导向部41和固定部42(本实施例中，导向部41和固定部42通过阻挡部43间接连接在一起，但不局限于此，在其它实施例中，导向件4也可以只由导向部41和固定部42组成，这时导向部41和固定部42直接连接在一起)，阻挡部43的径向长度大于导向部41和固定部42的径向长度。优选的，阻挡部43与固定部42之间为斜面过渡。阻挡部43的设置，可以起到固定部42在插入到导向孔31中后，导向件4在没有外力的情况下不会直接从导向孔31中脱出的效果。
参考图3和图4，导向部41、固定部42和阻挡部43一体形成，这样便于一次加工成型，但不局限于此，导向部41、固定部42和阻挡部43之间还可以通过扣接、插接或者螺接等方式固定在一起，在此不再详述。。
参考图3和图4，两个连接单元为相对设置的公头5和母头6，公头5和母头6可替换地分别固定设置在转接座3和第二连接件2上(即公头5固定设置在转接座3上时，则母头6固定设置在第二连接件2上；或者公头5固定设置在第二连接件2上，则母头6固定设置在转接座3上)，公头5和母头6之间为间隙配合。公头5背离第二连接件2的一端为插针51，母头6上开设有插槽61，导向件4插入到导向孔31中，则插针51插入到插槽61中，插针51与插槽61之间为间隙配合，且插针51与插槽61的槽壁之间的间隙小于固定部42与导向孔31的孔壁之间的间隙。
参考图3和图4，转接座3通过弹性固定件7设置在第一连接件1上。优选的，弹性固定件7为弹性螺锁件，包括螺锁杆71和弹簧72，转接座3上还开设有安装孔32，螺锁杆71一端通过弹簧72连接在转接座3上，螺锁杆71另一端穿过安装孔32并固定在第一连接件1上。
本实施例中，螺锁杆71与安装孔32的孔壁之间具有间隙。转接座3通过弹性固定件7设置在第一连接件1上，且螺锁杆71与安装孔32的孔 壁之间具有间隙，使得转接座3本身也可相对第一连接件1做适当位置调整，从而进一步增强了该对准结构的调节效果。
实施例2
参考图1和图2，本实施例提供一种COB无缝拼接显示系统，COB无缝拼接显示系统包括至少两个对准结构，对准结构的具体数量和位置排布可根据实际需求来定，在此不再详述。第一连接件1为箱体，箱体之间一体成型；第二连接件2为模组，模组之间相互拼接在一起，但不局限于此，在其它实施例中，箱体之间还可以是固定连接在一起。
将对准结构应用到COB无缝拼接显示系统中，当模组固定到箱体上以后，模组之间还可以进行位置调整，从而能够很好的消除模组之间的间隙，大大增强该显示产品的整体显示效果。
参考图5，两个对准结构在拼接过程中，模组与模组之间具有缝隙21，由于本实施例的模组可以相对箱体进行适当的位置调节，从而在组装该系统过程中能消除两个模组之间的缝隙21，最终实现无缝拼接在一起。
工作原理：
本实施例的COB无缝拼接显示系统共用一个箱体，当要将多个模组拼接在一起时，先将每个模组通过导向件安装到对应的箱体上，此时模组与模组之间存在缝隙，调节模组与模组之间的相对位置，消除模组与模组之间的缝隙，最后将模组完全固定。具体实施过程中，模组可以通过磁性件，如磁铁吸附在箱体上，磁性件可以提供足够的吸附力使得模组固定在箱体上，当模组与模组之间的缝隙调节好后，模组则可以利用磁性件进行定位固定。
显然，本发明的上述实施例仅仅是为清楚地说明本发明技术方案所作的举例，而并非是对本发明的具体实施方式的限定。凡在本发明权利要求书的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
