 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明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仅用以解释本发明，并不用于限定本发明。
如图1至图3所示，是本发明实施例提供的一种拼接式LED箱体，包括成排且成列分布且相互拼接的至少四个LED箱100，LED箱100相对相邻的LED箱100的拼接面上设置有连接件。
连接件包括第一连接件、第二连接件、第三连接件以及第四连接件，第一连接件和第三连接件设置在LED箱100上相邻的两个侧面，第二连接件设置在LED箱100上相对第一连接件的侧面，第四连接件设置在LED箱100上相对第三连接件的侧面，相邻两个LED箱100体拼接时，第一连接件和第二连接件配合连接，第三连接件和第四连接件配合连接。本实施例示出的拼接式LED箱100体具有四个LED箱100，每一列和每一排均具有两个LED箱100。在其他实施例中，拼接式LED箱100体也可以包括9个、16个、25个或36个等多个LED箱100。
相较于现有技术，本发明实施例的拼接式LED箱100在拼接时，第一连接件和第二连接件配合连接，第三连接件和第四连接件配合连接，从而确保箱体之间的精密定位。
具体的，第一连接组件包括限位滑槽111和定位销孔112，第二连接组件包括与限位滑槽111适配的限位滑块121以及与定位销孔112适配的定位销122，相邻两个LED箱100拼接时限位滑块121可在限位滑槽111上滑动以实现相邻两个LED箱100的限位，限位完成后定位销122插入定位销孔112中从而实现相邻两个LED箱100的定位。通过先限位后定位的装配顺序，确保LED箱100在水平和垂直方向精密定位。
第三连接组件包括定位柱131和限位槽132，第四连接组件包括与定位柱131适配的定位孔141以及与限位槽132适配的限位块142，相邻两个LED箱100拼接时定位柱131插入定位孔141中且限位块142插入限位槽132中。通过定位柱131与定位孔141的配合实现相邻两个LED箱100的定位，再通过限位槽132和限位块142的配合进行进一步定位，从而确保LED箱100之间的精密定位。
需要说明的是，在另一些具体实施方式中，第一连接组件也可以是限位滑槽111和定位销122，此时第二连接组件为与限位滑槽111适配的限位滑块121以及与定位销122适配的定位销孔112。第三连接组件可以是定位柱131和限位块142，此时第四连接组件为与定位柱131适配的定位孔141以及与限位块142适配的限位槽132。
本实施例中，限位槽132和限位滑槽111为方形槽，相应地，限位块142和限位滑块121为方形块。在其他实施方式中，限位槽132也可以为V形槽、U形槽等，本实施例对此不作限制。
本实施例中，LED箱100包括相对的第一侧面10、第二侧面（未示出）以及连接第一侧面10和第二侧面的第三侧面30和第四侧面（未示出），第一侧面10和第二侧面沿竖直方向延伸，第三侧面30和第四侧面沿水平方向延伸，第一连接件设置在第一侧面10上，第二连接件设置在第二侧面上，第三连接件设置在第三侧面30上，第四连接件设置在所述第四侧面上。
以其中一个LED箱100为基准，假设该LED箱100为A箱，位于A箱左侧的LED箱100为B箱,位于A箱右侧的LED箱100为C箱，位于A箱上方的LED箱100为D箱,位于A箱下方的LED箱100为E箱。则A箱可通过第一连接件与B箱的第二连接件相连，通过第二连接件与C箱的第一连接件相连，通过第三连接件与D箱的第四连接件相连，通过第四连接件与E箱的第三连接件相连。或者，A箱通过第二连接件与B箱的第一连接件相连，通过第一连接件与C箱的第二连接件相连，通过第四连接件与D箱的第三连接件相连，通过第三连接件与E箱的第四连接件相连。可以理解的，第一侧面10和第二侧面也可以沿水平方向延伸，第三侧面30和第四侧面则沿竖直方向延伸。此时第一连接件和第二连接件位于LED箱100的顶部或底部，第三连接件和第四连接件位于LED箱100的左侧或右侧。
优选的，如图4和图5所示，定位柱131具有两个，两个定位柱131对称设置在第三侧面30两侧。限位滑槽111具有两个，两个限位滑槽111分别设置在第一侧面10的顶部边缘和底部边缘，限位滑块121具有两个，两个限位滑块121分别设置在第二侧面的顶部边缘和底部边缘。限位槽132同样具有两个，两个限位槽132分别设置在第三侧面30的两个端部边缘，限位块142具有两个，两个限位块142分别设置在第四侧面的两个端部边缘。通过两个端部同时进行限位，使得相邻两个LED箱100更加精准地对齐。另外，定位销孔112设置在第一侧面10的中部，定位销122设置在第二侧面的中部。
在另一些具体实施方式中，可以是第一侧面10的顶部边缘设置限位滑槽111，底部边缘设置限位滑块121；第二侧面的顶部边缘设置限位滑块121，底部边缘设置限位滑槽111。同理，可以是第三侧面30的左侧边缘设置限位槽132，右侧边缘设置限位块142；第四侧面的左侧边缘设置限位块142，右侧边缘设置限位槽132。可以是第三侧面30的左侧边缘设置定位柱131，右侧边缘设置定位孔141；第四侧面的左侧边缘设置定位孔141，右侧边缘设置定位柱131。
如图6和图7所示，本实施例的拼接式LED箱体还包括吊装结构，吊装结构包括吊架200，吊架200设置在排列于上方的LED箱100的顶部。
吊装结构还包括设于吊架200和LED箱100之间的若干个第一连接件320和若干个第二连接件330，第一连接件320和第二连接件330的两端分别与吊架200和LED箱100固定连接，第一连接件320和第二连接件330均匀分布在吊架200和LED箱100的连接面上。由于第一连接件320和第二连接件330均匀分布在吊架200和LED箱100的连接面上，在吊装拼接式LED箱体时，LED箱100上的受力点呈均匀分布状态，不存在受力集中点，使得拼接式LED箱体能够均匀受力从而保证稳定的提升状态。
具体的，LED箱100包括框架110以及盖接固定在框架110一侧的门板120，吊架200由若干个吊架单体210连接而成，第一连接件320包括连接片321和螺钉322，吊架单体210包括固定在框架110顶部的底板211以及自底板211的两个长轴侧向上延伸的侧板212，连接片321一端夹设固定在框架110和门板120之间，连接片321另一端通过螺钉322固定在侧板212上。
连接片321包括第一固定部3211、第二固定部3212以及连接第一固定部3211和第二固定部3212的连结部3213，第一固定部3211和第二固定部3212相互平行，连结部3213垂直于第一固定部3211和第二固定部3212，第一固定部3211固定在侧板212上，第二固定部3212夹设固定在框架110和门板120之间，连结部3213与底板211的底面贴合。连接片321的这一特殊结构，使得LED箱100和吊架200的连接更加牢固。
另外，本实施例的第二连接件330为快速安装锁，框架110包括与底板211固定的顶边框111，快速安装锁依次穿过顶边框111和底板211并将顶边框111和底板211锁合。第二连接件330的设置增加了LED箱100和吊架200的连接点数量，不仅进一步增强了LED箱100和吊架200连接的牢固性，而且在拼接式LED箱体吊装过程中，也增加了LED箱100上的受力点，使得拼接式LED箱体在吊装过程中能够均匀受力。
具体的，本实施例的拼接式LED箱体由成排且成列的4个LED箱100拼接而成，吊架200设置在上排的两个LED箱100上方。第一连接件320具有五个，分别设置在左侧的LED箱100的顶部左侧边缘、左侧的LED箱100的顶部中心、两个LED箱100的连接处、右侧的LED箱100的顶部中心以及右侧的LED箱100的顶部右侧边缘。第二连接件330具有四个，第二连接件330设置在相邻两个第一连接件320之间。在其他可能的实施方式中，也可以将第二连接件330和第一连接件320的位置互换，第二连接件330的数量为五个，第一连接件320的数量为四个且设置在相邻两个第二连接件330之间。还可以增加第一连接件320和第二连接件330的数量，比如设置七个第一连接件320和六个第二连接件330等，本实施例不限制第一连接件320和第二连接件330的数量，只要保证第一连接件320和第二连接件330均匀分布即可。
请进一步参阅图8和图9，该LED箱体吊装结构还包括第三连接件340和连接螺杆350，吊架200由吊架单体210通过第三连接件340和连接螺杆350连接而成，吊架单体210还包括设置在两个侧板212的顶部并连接两个侧板212的顶板213，其中一个吊架单体210的两个侧板212分别与相邻的吊架单体210的位于同一侧的侧板212之间一一对应抵接，第三连接件340设置在两个吊架单体210的对接处，第三连接件340包括相对设置的两个竖向连接臂341以及连接两个竖向连接臂341的横向连接臂342，两个竖向连接臂341分别对应不同侧的侧板212设置且竖向连接臂341与位于同一侧且相互抵接的两个侧板212贴合，连接螺杆350穿过相对的两个竖向连接臂341以及相对的两个侧板212从而实现第三连接件340与吊架200的连接。可以在竖向连接臂341以及侧板212上开设通孔，同一根连接螺杆350依次穿过一侧的侧板212、与该侧板212贴合的竖向连接臂341、与该竖向连接臂341对应的另一竖向连接以及另一侧的侧板212，从而将第三连接件340与吊架单体210两侧的侧板212紧密地连接。相邻两个吊架单体210之间通过第三连接件340牢牢锁紧，而且易于实施，小巧轻便，具有很强的实用性。
另外，如图8所示，相邻的两个吊架单体210的两个顶板213之间间隔设置，在两个吊架单体210的连接处形成一个缺口2131，第三连接件340设置在缺口2131处，从而方便调整第三连接件340的位置，使得第三连接件340和吊架单体210可以更加牢固地连接。
在其中一种可能的实施方式中，第三连接件340位于相对的两个侧板212之间，竖向连接臂341的外侧面与位于同一侧且相互抵接的两个侧板212的内侧面之间相互贴合。在另外一种可能的实施方式中，第三连接件340的两个竖向连接臂341之间的距离大于相对的两个侧板212之间的距离，竖向连接臂341的内侧面与位于同一侧且相互抵接的两个侧板212的外侧面之间相互贴合。
优选的，连接螺杆350的数量为四个，连接螺杆350呈两排设置，每一排设有两个连接螺杆350，上排的两个连接螺杆350的距离小于下排的两个连接螺杆350的距离，如此可使竖向连接臂341与侧板212之间贴合得更加紧密。在另一些具体的实施方式中，可以设置连接螺杆350的数量为五个、六个、七个、八个等，连接螺杆350可以呈三排、四排、五排等设置，本实施例不限定连接螺杆350的数量及排列方式。可选的，连接螺杆350的直径为10mm。
另外，请参阅图6、图10和图11，本实施例的LED箱体吊装结构还包括设置在吊架单体210上的支架370以及至少两组固定吊架单体210和支架370的调节组件，调节组件包括沿竖直方向穿设在吊架单体210的顶部的螺杆360，LED箱体吊装结构还包括螺合于螺杆360上的第一螺母390，支架370套设于螺杆360上并置于吊架单体210上方，第一螺母390与吊架单体210固定连接，通过旋拧螺杆360调整吊架单体210相对螺杆360的高度位置从而可调节吊架单体210的顶面平齐，该结构易于实施，具有很强的实用性。
在一些实施例中，调节组件还包括螺栓，可以通过旋拧螺栓从而带动螺杆360旋转，以此调整吊架单体210相对螺杆360的高度位置从而可调节吊架单体210的顶面平齐。在一种具体实施方式中，如图10和图11所示，调节组件为外六角螺栓，外六角螺栓的头部36与支架370的顶部之间设置有垫片37和弹垫38，垫片37可保护支架370顶部和外六角螺栓的接触面，弹垫38则提供了螺栓预紧力。
螺杆360的位于顶板213以下的长度应足够长，留给第一螺母390足够的调整空间，但也不宜过长，不能与底板211接触。本实施例中，第一螺母390固定于顶板213的底面，支架370抵接顶板213的顶面。优选的，第一螺母390与顶板213的连接采用焊接的方式，使得第一螺母390与顶板213的连接更加紧密。
如图10和图11所示，在一种可能的实施方式中，支架370包括沿与侧板212板面垂直方向延伸的底臂371以及自底臂371的两个长轴边缘向上延伸的侧臂372，底臂371套设于螺杆360上并置于吊架单体210上方，底臂371抵接顶板213的顶面。支架370的数量为两个，螺杆360的数量为两个，两个螺杆360对称设置在吊架单体210的顶部。螺杆360的数量也可以为三个、四个、五个或六个等，本实施例对此不作限制。
如图12和图13所示，在另一种可能的实施方式中，支架370包括固定在吊架单体210上方的横梁373以及自横梁373一侧面朝与横梁373垂直方向延伸的边梁374，边梁374具有两个且两个边梁374呈对称设置，横梁373为内部中空结构，螺杆360穿过横梁373内部的中空区域。调节组件采用外六角螺栓，外六角螺栓的头部36与横梁373的顶部之间设置有垫片37和弹垫38，第一螺母390和顶板213之间也设置有垫片37。采用这种结构的支架370，使得支架370与吊架单体210之间的受力面积增大，受力可靠，从而提高吊架单体210的稳固程度和吊装的安全性。
优选的，支架370为钢结构支架370，具有强度高、自重轻、整体刚度好、抵抗变形能力强的优点。
另外，LED箱100还包括LED模组， LED模组和门板120安装在框架110的相对两面，如图14和图15所示，拼接式LED箱体还包括用于防护LED箱100的LED模组防护结构， LED模组防护结构包括设置在LED箱100的顶角处并包覆顶角的第一护角结构410。
具体的，请一同参阅图16，第一护角结构410包括夹设固定在框架110和门板120之间的第一固定板411、自第一固定板411的相邻两侧边朝远离门板120方向延伸的两个第一侧板412以及连接两个第一侧板412远离门板120一端的第一防护板413，第一侧板412延伸超出LED模组的表面所在平面。由于位于LED箱100顶角处的LED灯珠有三个面是完全暴露在外的，容易在运输或放置LED箱100的时候受到外力撞击或摩擦，而两个第一侧板412以及第一防护板413能够对这三个面进行有效的包覆，从而能够保证对LED灯珠的有效的屏障防护，保证在放置和运输LED箱100不会碰到LED灯珠而损坏LED灯珠。优选的，第一护角结构410具有四个，对应设置于LED箱100的四个顶角处。
本实施例中，LED模组防护结构还包括设置在LED箱100的侧边处并包覆侧边的第二护角结构420。请参阅图14和图17，第二护角结构420包括夹设固定在框架110和门板120之间的第二固定板421、自第二固定板421的对应LED箱100长轴边的侧边朝远离门板120方向延伸的第二侧板422以及自第二侧板422远离门板120一端朝与LED模组的表面所在平面平行的方向延伸的第二防护板423，第二侧板422延伸超出LED模组的表面所在平面。由于位于LED箱100侧边处的LED灯珠有两个面是完全暴露在外的，容易在运输或放置LED箱100的时候受到外力撞击或摩擦，而第二侧板422和第二防护板423能够对这两个面进行有效的包覆，从而能够保证对LED灯珠的有效的屏障防护。
优选的，第二护角结构420具有两个，两个第二护角结构420分别设置在LED箱100相对的两条长轴边处。在其他可能的实施方式中，在LED箱100相对的两条短轴边处也可以设置第二护角结构420。也可以在LED箱100的两条长轴边处和两条短轴边处均设置多个第二护角结构420，本实施例对第二护角结构420的数量不做限制。
优选的，第一护角结构410和第二护角结构420由低碳冷轧钢板材料、铝合金材料或工程塑胶材料制成，由低碳冷轧钢板材料、铝合金材料或工程塑胶材料制成的护角结构硬度高，强度好，而且使用寿命长，能够加大对LED灯珠的防护力度。当然，在其他实施方式中，第一护角结构410和第二护角结构420也可以选择由其他硬度高强度好的材料制成，本实施例不做限制。
如图18至图20所示，拼接式LED箱体还包括安装在LED箱100上的门锁结构，门锁结构包括钥匙510、壳体520、锁芯530、锁舌540以及微动开关组件550，壳体520固定在门板120朝向框架110一侧，锁芯530安装在壳体520内部，钥匙510可插入锁芯530中并带动锁芯530转动，锁舌540连接到锁芯530末端，锁舌540可随锁芯530转动。
微动开关组件550包括微动开关板551、微动开关552以及锁挡片553，微动开关板551固定在框架110上，微动开关552安装在微动开关板551的板面上，微动开关552与LED模组电连接，锁挡片553固定在微动开关板551上且与微动开关552间隔设置。当钥匙510顺时针转动90°时，锁舌540旋转到锁挡片553与微动开关552之间，由于锁挡片553对锁舌540的阻挡作用使得门板120呈锁紧状态，同时锁舌540触发微动开关552，LED模组开始正常工作；而当钥匙510顺时针转动角度不足90°时，锁舌540与微动开关552以及锁挡片553相互错开，门板120呈打开状态但此时微动开关552断开，LED模组停止工作，从而对LED模组的信息传输起保护作用。本实施例中，壳体520、锁芯530、锁舌540以及微动开关组件550均具有两组且对称设置在LED箱100的两侧。
本实施例中，当钥匙510顺时针转动0°时，锁舌540沿竖直方向向上延伸；当钥匙510顺时针转动90°时，锁舌540沿水平方向向左侧延伸。在其他可能的实施方式中，微动开关组件550可以设置在锁芯530的顶部，当钥匙510顺时针转动0°时，锁舌540沿水平方向向右延伸；当钥匙510顺时针转动90°时，锁舌540沿竖直方向向上延伸并位于锁挡片553与微动开关552之间。
另外，当钥匙510顺时针转动0°时或90°时，钥匙510可从所述锁芯530中拔出；当钥匙510顺时针转动角度不等于0°或90°时，钥匙510与锁芯530中的钥匙通道卡合而无法向外拔出。相较于传统的LED箱体门锁结构，钥匙510在0°和90°之间任意角度都能拔出，会造成即使门板120还没完全关闭，却误以为门板120已经关闭到位的假象。而本发明实施例的LED箱体门锁结构，钥匙510在旋转过程中，只有在顺时针转动角度为0°或90°位置才能拔出钥匙510，从而确保门板120能关闭到位，降低安全隐患。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
