发明实施例
本发明的实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图1～16及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本申请。
需说明的是，当部件被称为“固定于”或“设置于”另一个部件，它可以直接在另一个部件上或者间接在该另一个部件上。当一个部件被称为是“连接于”另一个部件，它可以是直接或者间接连接至该另一个部件上。术语“上”、“下”、“左”、“右”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制，对于本领域的普通技术人员而言，可以根据具体情况理解上述术语的具体含义。术语“第一”、“第二”仅用于便于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明技术特征的数量。“多个”的含义是两个或两个以上，除非另有明确具体的限定。
为了说明本申请所述的技术方案，以下结合具体附图及实施例进行详细说明。
参阅图1和图2所示，本申请第一实施例的LED显示屏系统100，其中，LED显示屏系统100包括LED显示屏10和用于支撑LED显示屏10的支撑架20。图1中LED显示屏系统100包括2具支撑架20以及8个相互拼接的拼接单元11，图2中的LED显示屏系统100包括1具支撑架20以及4个相互拼接的拼接单元11。需要说明的是，本实施例中的LED显示屏系统100中的LED显示屏10至少可以包括2个拼接单元11，支撑架20的数量至少为一个。需要说明的是，本申请中的拼接单元11可以是用于显示的LED显示屏箱体、或LED显示屏模组，也可以是其他通过拼接而构成一个具有实际应用价值的整体的LED显示屏的其他单元，比如控制箱，配电箱，工具箱等，在此不作限制。
如图2至图4所示，支撑架20包括第一支杆21和支架22，第一支杆21沿第一方向延伸；支架22连接于第一支杆21上，进一步地，支架22固定连接于第一支杆21上以增强整个支撑架20的强度和刚度。支架22包括第二支杆221和第一连接组件222，其中，第二支杆221沿第二方向延伸。本实施例中，第一支杆21沿第一直线方向A延伸，第二支杆221沿第二直线方向B延伸，第一直线方向A和第二直线 方向B相互垂直或异面。可以理解的，第一方向和第二方向均可以是曲线方向，也即是说，在其他实施例中，第一支杆21和第二支杆221可以呈曲线延伸或者局部曲线延伸。第二支杆221的一端连接至第一支杆21，第二支杆221的另一端连接有第一连接组件222。本实施例中，一个第一支杆21上连接有四个支架22，两两一组，两个支架22紧靠连接至第一支杆21形成一组，各组支撑架20沿第一直线方向A间隔一定距离，该距离约等于一个拼接单元11的竖直高度。需要说明的是，一具支撑架20至少具有两个支架22，且两个支架22相对于第一支杆21的位置不定，不一定如本实施例中两个支架22在第一直线方向A相互紧靠。
如图3至图5所示，支撑架20具有展开状态和折叠状态，图3和图4中支撑架20为展开状态，图5中支撑架20为折叠状态。具体地，支架22相对于第一支杆21构成活动连接，进一步地，支架22相对于第一支杆21构成转动连接。当支架22相对于第一支杆21转动至第二支杆221平行于第一支杆21时，支撑架20为折叠状态，当支架22相对于第一支杆21转动至第二支杆221不平行于第一支杆21时，支撑架20为展开状态。本实施例中，支撑架20为展开状态时，第二支杆221基本垂直于第一支杆21，也即是第二支杆221与第一支杆21之间构成的角度约为90°。在其他实施例中，支撑架20为展开状态时，第二支杆221与第一支杆21之间构成的角度可以是其他角度值。另外，由于本实施中两个支架22紧靠安装至第一支杆21，当支撑架20为展开状态时，两个紧靠的支架22在第一直线方向A基本位于同一高度，也即是说两个支架22能够在同一水平线上实现与两个水平相邻的拼接单元11的连接。该设计使得连接两个水平相邻的拼接单元11时更加方便，同时也能保证两个水平相邻的拼接单元11结构的同一性，不需为适应不同支架22在第一直线方向A的高度差而做出结构调整。
如图6至图8所示，第一连接组件222包括连接部222a。连接部222a用于与拼接单元11构成可拆卸连接，连接部222a设置于第二支杆221的另一端，连接部222a相对于拼接单元11至少具有可以相互切换的锁定位置和解锁位置，当连接部222a位于锁定位置时，拼接单元11和连接部222a在垂直于拼接单元11的连接平面的方向相对固定，当连接部222a位于解锁位置时，连接部222a相对于拼接单元11可拆卸。
第一连接组件222还包括第一轴222b，连接部222a转动连接至第一轴222b。具体地，连接部222a绕第一轴222b的轴线转动，转动角度不限。连接部222a相对于拼接单元11至少具有一个锁定位置和一个解锁位置。当连接部222a相对于第一轴222b转动至某一个或者多个角度时，连接部222a处于锁定位置，当连接部222a相对于第一轴222b转动至某一个或者多个角度时，连接部222a处于锁定位置。本实施例中，连接部222a相对于拼接单元11具有一个锁定位置和一个解锁位置，且连接部222a从锁定位置切换至解锁位置时，相对于第一轴222b转动角度约为90°。
第一连接组件222还包括第一定位部222c，当连接部222a位于锁定位置时，第一定位部222c与连接部222a配合并将连接部222a固定至锁定位置。也即是说，当连接部222a相对于拼接单元11位于锁定位置时，连接部222a通过和拼接单元11的配合使得拼接单元11和连接部222a在垂直于拼接单元11的连接平面的方向相对固定，或者说在平行于第一轴222b的轴线方向相对固定；在此基础上，通过第一定位部222c与连接部222a配合使得拼接单元11和连接部222a在平行于拼接单元11的连接平面的方向相对固定，或者说在第一轴222b的圆周方向相对固定，从而实现示构件和连接部222a的固定连接。
第一定位部222c在垂直于第一轴222b的轴线的方向与第一轴222b构成活动连接，用户可以通过操作第一定位部222c使得第一定位部222c相对于连接部222a移动。本实施例中，第一连接组件222还包括第二轴222d，第二轴222d沿垂直于第一轴222b的轴线方向连接至第一轴222b，第一定位部222c转动连接至第二轴222d且相对于第二轴222d沿其轴线方向可移动，具体地，用户可以通过操作第一定位部222c使得第一定位部222c沿第二轴222d的轴线方向来回滑动，从而使得第一定位部222c和连接部222a相互配合或者相互分离。由于第二轴222d垂直于第一轴222b且第二轴222d穿过第一轴222b且第二轴222d在第一轴222b的径向突出于第一轴222b，因此，在连接部222a自身结构的基础上，第二轴222d限制了连接部222a绕第一轴222b的转动范围，具体地，连接部222a绕第一轴222b的转动范围为0～90°，在0°和90°位置分别对应连接部222a的锁定位置和解锁位置。
第一连接组件222还包括第一偏压件222e，在第一定位部222c沿平行于第二轴222d的轴线的第三方向C运动时，第一偏压件222e对第一定位部222c施加一个与 第三方向C相反的偏压力。第一偏压件222e可以为弹性件，本实施例中，第一偏压件222e为弹簧，第一定位部222c受外力作用从初始位置沿平行于第二轴222d的轴线的第三方向C运动时，弹簧处于拉伸状态，对第一定位部222c施加一个与第三方向C相反的弹力，当第一定位部222c所受外力撤销时，在弹力的作用下，弹簧回归原长，从而带动第一定位部222c回到初始位置。这里的第三方向C指的是沿第一轴222b的径向远离第一轴222b的轴线的方向，初始位置指的是第一定位部222c最靠近连接部222a的位置。可以理解的，第一偏压件222e还可以是除弹簧以外的其他结构，只要能够对第一定位部222c产生上述力作用即可。
连接部222a的表面设置有凹陷部222f，凹陷部222f向第一轴222b的径向凹陷且沿第一轴222b的周向延伸，第二轴222d穿过凹陷部222f，凹陷部222f沿第一轴222b的轴线方向的尺寸大于第二轴222d的最大径向尺寸。具体的，凹陷部222f为设置于连接部222a侧面的凹槽，侧面为分布于第一轴222b的周向的面。凹槽的设置主要是为了保证在设置与第一轴222b相交的第二轴222d的情况下保证连接部222a仍然能够绕第一轴222b转动一定角度具体地，在连接部222a的侧面沿第一轴222b的圆周方向设置有两段不连续的凹槽，两段凹槽关于第一轴222b中心对称，每段凹槽沿第一轴222b的周向延伸的弧长所对应的圆心角约为90°。凹槽沿第一轴222b的径向凹陷的深度不限，凹槽沿第一轴222b的轴向的高度大于第一轴222b突出于第一轴222b的部分的径向尺寸。
连接部222a的表面还设置有第一配合部222g，第一定位部222c的表面设置有第二配合部222h；当连接部222a位于锁定位置时，第一配合部222g和第二配合部222h构成轴孔配合。具体地，第一配合部222g位于连接部222a的侧面，第二配合部222h设置于第一定位部222c的与连接部222a相接触的面。本实施例中，第一配合部222g和第二配合部222h均近似为圆环型沟槽状，两个圆环型沟槽的进行尺寸不同且满足使得第一配合部222g和第二配合部222h相互卡接，形成至少两处轴孔配合。
连接组件222还包括供用于操作的操作部222i，操作部222i连接至连接部222a且驱动连接部222a在锁定位置和解锁位置之间切换。本实施例中，操作部222i为连接至连接部222a的手柄，方便用户握持以驱动连接部222a绕第一轴222b转动。可 以理解的，在其他实施例中，操作部222i可以为拨扭、旋钮、扳机等其他结构，在此不作限制。进一步得，操作部222i转动连接至连接部222a，操作部222i绕第三轴222j转动，第三轴222j的轴线垂直于第一轴222b的轴线。在第一轴222b的周向，操作部222i相对于连接部222a固定，但操作部222i可以绕第三轴222j在平行于第一轴222b的轴线的平面内转动。该设计使得操作部222i相对于连接部222a具有多种形态，将操作部222i展开，此时操作部222i沿垂直于第一轴222b的方向延伸，方便用于操作；将操作部222i折叠，此时操作部222i沿平行于第一轴222b的方向延伸，方便收纳。
另外，操作部222i还设置有第一档位部222k，连接部222a设置有第二档位部222l，第一档位部222k和第二档位部222l配合以使操作部222i相对于连接部222a转动至某位置时固定至该位置；进一步地，至少两个第二档位部222l分别与第一档位部222k配合以使操作部222i相对于连接部222a转动至多个不同位置时固定至该位置；或者，至少两个第一档位部222k分别第二档位部222l配合以使操作部222i相对于连接部222a转动至多个不同位置时固定至该位置。
本实施例中，第一档位部222k为设置于操作部222i端部表面的凹槽，第二档位部222l为与该凹槽配合的圆球，圆球固定连接至连接部222a。具体的，凹槽数量至少两个，本实施例中为三个，分别对应手柄相对第一轴222b平行的两个位置和垂直90°的位置。作为一种可选的实施方式，第一档位部可以是设置于操作部端部表面的圆球，第二档位部为设置于连接部的凹槽。可以理解的，第一档位部和第二档位部的具体结构不限于上述两种实施方式。
第一连接组件222转动连接至第二支杆221。本实施例中，第一连接组件222绕第四轴223在垂直于第一支杆21的延伸方向(即第一直线方向A)的平面内转动。作为一种可选择的实施方式，第一连接组件绕第四轴在平行于第一支杆的延伸方向(即第一直线方向)的平面内转动。作为另一种可选择的实施方式，第一连接组件铰接至第二支杆，第一连接组件相对于第二支杆可以在多个方向转动。通过第一连接组件222绕第四轴223的转动，使得第一连接组件222相对于第二支杆221可在不同位置间切换，从而匹配多种不同形态的LED显示屏10，例如平面LED显示屏10和弧形LED显示屏10。
图6中的四个第一连接组件222(操作部222i未示出)相对于第二支杆221构成不同的角度。第一连接组件222相对于第二支杆221的可转动角度范围大于0°且小于等于20°。进一步地，第一连接组件222相对于第二支杆221的可转动角度范围大于0°且小于等于90°。本实施例中，第一连接组件222相对于第二支杆221的可转动角度约为70°。第一连接组件222设置有第三档位部222m，第二支杆221设置有第四档位部221a，第三档位部222m和第四档位部221a配合以使第一连接组件222相对于第二支杆221转动至某位置时固定至该位置；进一步地，至少两个第三档位部222m分别和第四档位部221a配合以使第一连接组件222相对于第二支杆221转动至多个位置时固定至该位置；或者，至少两个第四档位部221a分别和第三档位部222m配合以使第一连接组件222相对于第二支杆221转动至多个位置时固定至该位置。
本实施例中，第三档位部222m为设置于连接部222a的凹槽，第四档位部221a为与该凹槽配合的圆球，圆球固定连接至第二支杆221。具体的，凹槽数量至少两个，本实施例中为三个，分别对应第一轴222b平行或重合于第二支杆221延伸方向的位置，以及第一轴222b相对于第二支杆221的延伸方向构成+35°、-35°的位置。如图6所示，当第一轴222b相对于第二支杆221的延伸方向构成+35°或-35°时，连接部222a与平面的LED显示屏10构成面接触。作为一种可选的实施方式，第三档位部可以是设置于第二支杆表面的圆球，第四档位部为设置于连接部的凹槽。可以理解的，第三档位部和第四档位部的具体结构不限于上述两种实施方式。
如图2、图9和图10所示，支架22还包括第二连接组件224，第二连接组件224固定连接至第一支杆21，支架22与第二连接组件224构成转动连接。第二连接组件224连接第一支杆21和支架22，第一支杆21与第二连接组件224通过紧固件与第二连接组件224构成固定的连接，进一步地，第一支杆21与第二连接组件224通过紧固件与第二连接组件224构成可拆卸的连接。本实施例中，紧固件包括螺钉、螺母、螺栓等。第二连接组件224包括连接轴224a和连接本体224b，连接轴224a与支架22构成转动连接，连接本体224b与第一支杆21构成固定连接，连接轴224a安装至连接本体224b。连接轴224a的轴线垂直于第一支杆21，因此支架22能够 在平行于第一支杆21的平面内转动。
支架22还包括第二定位部225，第二定位部225连接第二支杆221和连接本体224b以将支架22锁定在相对连接组件的预设位置。本实施例中，支架22至少能够锁定至平行于第一支杆21的位置和垂直于第一支杆21的位置。第二连接组件224上设置有至少两个与第二定位部225配合的第三配合部224c，在支架22转动至上述两个位置时分别于第二定位部225配合。
具体地，第二定位部225安装至第二支杆221的端部，第二定位部225包括“T”型杆、握持部225a以及第二偏压件225b。至少部分“T”型杆设置于第二支杆221壳体内部，“T”型杆包括横杆225c和竖杆225d，握持部225a安装至竖杆225d，第二偏压件225b安装至第二支杆221壳体和横杆225c之间，横杆225c与第三配合部224c相配合。第二偏压件225b具体为弹性件，本实施例中为弹簧，套装至竖杆225d表面。当握持部225a受外力以改变横杆225c第二支杆221壳体之间的空间大小时，第二偏压件225b对横杆225c施加一个与该操作方向相反的偏压力，当外力撤销时，第二定位部225在偏压力的作用下回到原位置。原位置即第二定位部225和第三配合部224c相配合的位置。
本实施例中，第三配合部224c为设置在第二连接组件224上的凹槽，具体为设置于连接本体224b上方的凹槽，横杆225c与凹槽构成轴孔配合从而使得支架22相对于第一支杆21在连接轴224a的圆周方向固定。一个连接本体224b上的凹槽的数量至少为两组，每组凹槽至少包括一个凹槽。其中一组凹槽的开口方向平行于第一支杆21的延伸方向，另一组凹槽的开口方向垂直于第一支杆21的延伸方向，从而使得支架22能够相对于第一支杆21折叠或者展开。另外，如图5所示，两个紧靠安装的支架22的折叠方向相反，这使得支架22在折叠时避开与连接主体发生干涉，方便储存运输。
如图11和图12所示，第一支杆21的一端设置有连接套筒211，另一端设置有连接端部212，一根第一支杆21的连接端部212与另一根第一支杆21的连接套筒211构成可拆卸连接以连接两个支撑架20。具体的，一根第一支杆21的连接端部212与另一根第一支杆21的连接套筒211构成螺纹连接以连接两个支撑架20。在连接套筒211的内表面设置有内螺纹，在连接端部212的外表面设置有外螺纹。可以 理解的，在其他实施方式中，连接部端部和连接套筒可以构成磁性连接、卡扣连接等多种可拆卸连接方式。
另外，第一支杆21的一端还设置有第三定位部213，第三定位部213靠近连接套筒211或者连接端部212且与两者中的至少一个相连接以固定连接套筒211和/或连接端部212相对于第一支杆21的位置。本实施例中，第三定位部213设置于连接端部212的外螺纹上方位置，连接套筒211上设置有与第三定位部213配合的第四配合部211a，当连接套筒211连接至连接端部212后，第三定位部213和第四配合部211a相配合从而固定连接套筒211的位置。具体地，第三定位部213为转动拨扭，第三定位部213包括定位轴213a、第三偏压件213b以及定位本体213c。定位本体213c转动连接至定位轴213a，第三偏压件213b设置于定位轴213a与定位本体213c之间，第三偏压件213b具体为弹簧。用户通过转动定位本体213c以改变定位本体213c的位置，从而固定或者释放连接套筒213，在定位本体213c不受外力时，定位本体213c在第三偏压件213b的偏压力作用下始终处于初始位置，即固定连接套筒213的位置。
如图2、图13至图15所示，拼接单元11上设置有配合件112，配合件112与拼接单元11构成固定连接或者一体成型；配合件112与连接部222a配合且构成可拆卸连接。当支撑架20连接至拼接单元11时，连接部222a和配合件112构成绕第一轴222b的转动连接；连接部222a沿第一轴222b的径向方向形成有凸起部222m，配合件112沿第一轴222b的径向方向形成有腔体112a，当连接部222a位于锁定位置时，凸起部222m与腔体112a配合，同时，配合件112还形成有阻挡部112b，凸起部222m与阻挡部112b通过尺寸干涉在垂直于所述拼接单元11的连接平面的方向相对固定，或者说在沿第一轴222b的轴线方向相对固定。本实施例中，配合件112设置于各个拼接单元11的后侧的中心位置，拼接单元11具体为用于拼接成LED显示屏10的箱体。
图16所示为本申请的第二实施例的用于LED显示屏的支撑架200，该支撑架的具体结构与第一实施例中的LED显示屏10中的支撑架20相同，在此不作赘述。
本领域技术人员在考虑说明书及实践这里公开的申请后，将容易想到本申请的其它实施方案。本申请旨在涵盖本申请的任何变型、用途或者适应性变化，这 些变型、用途或者适应性变化遵循本申请的一般性原理并包括本申请未公开的本技术领域中的公知常识或惯用技术手段。应当理解的是，本申请并不局限于上面已经描述并在附图中示出的精确结构，并且可以在不脱离其范围进行各种修改和改变。本申请的范围仅由所附的权利要求来限制，本说明书内容不应理解为对本申请的限制。
