本发明的实施方式
为了便于理解本申请,下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳实施方式。但是,本申请可以以许多不同的形式来实现,并不限于本文所描述的实施方式。相反地,提供这些实施方式的目的是使对本申请的公开内容理解的更加透彻全面。
除非另有定义,本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的,不是旨在于限制本申请。
实施例一
针对现有技术的拼接片与中框的配合度不足,导致安装效率难以提高的问题,本实施例提供一种拼接片,如图2和图5所示,该拼接片20用于对至少两个中框(中框的一种结构参见图1所示)进行拼接(参见图4、图6-1和图6-2)。
本实施例中,中框10也可称之为“箱体”,其作为显示设备中显示模组(也可称之为显示面板)、电源、信号转接卡等主要部件的安装载体,具有较高的强度与承重能力,例如,在一些示例中,中框10为金属或合金材质。中框10为框架结构,其具有四个边梁11,四个边梁11首尾相连使得中框10的外轮廓呈矩形。呈矩形的中框10具有四个顶点,即具有四个顶角,在本实施例中将顶角对应的区域称为“顶角区域”。中框10上四个顶角区域中至少一个设有用于与拼接片20配合的拼接片装配区,拼接片20用于通过至少两个第一螺纹紧固件30将至少两个中框10拼接到一起,所以在拼接中框10时,拼接片20同时与至少两个中框10连接固定在一起。在本实施例中将中框10供显示模组安装的一侧称为中框10的前侧,与前侧相对的一侧为中框10的后侧,通常情况下,中框10的后侧可供显示设备的后盖安装。
在本实施例中,拼接片20包括片状的片体以及设置在片体上的拼接通孔与定位销钉。请参见图2提供的一种拼接片20与第一螺纹紧固件30配合的示意图:拼接片20上设置有至少两个无螺纹的拼接通孔201,这至少两个拼接通孔201对应至少两个中框10。在图2中,拼接片20大致呈矩形,其上设置有四个拼接通孔201,分别位于拼接片的4个角,且每一个拼接通孔201分别对应一个中框10,因此,图2示出的拼接片20可以将四个中框10拼接到一起。在拼接片装配区中设置有拼接螺孔101(参考图1和图3),拼接螺孔101贯穿中框10的前侧与后侧,拼接螺孔101与拼接通孔201一一对应,二者与第一螺纹紧固件30配合,第一螺纹紧固件30一端穿过拼接通孔201与中框上的拼接螺孔101通过螺纹连接锁紧,并实现拼接片20与中框10的锁紧。
在本实施例中,请参见图1与图3,拼接片装配区包括位于中框10前侧的装配前区100a(图1中虚线框所示的位置)及位于中框10后侧的装配后区100b(图1中虚线框所示的位置),装配前区100a与装配后区100b位置上是相对的。在本实施例中,对中框10进行拼接时,可以将拼接片置于中框10的前侧,与装配前区100a配合(参考图4);也可以选择将拼接片置于中框10的后侧,与装配后区100b配合(参考图6-1和图6-2);甚至还有一些示例中,中框10的装配前区100a与装配后区100b中可以同时设置有拼接片。不过通常情况下,对于一个拼接片装配区,只需要有一侧与拼接片配合即可。
请结合图1至图3,可以理解的是,利用装配前区100a与拼接片20配合时,拼接片20位于中框10的前侧,这适宜于安装人员从中框10的前侧对显示模组进行拼接安装的场景,在这种情况下,第一螺纹紧固件30的一端可以从中框10的前侧依次穿过拼接通孔201并与拼接螺孔101通过螺纹连接紧固连接(参考图1和图4所示);利用装配后区100b与拼接片20配合时,拼接片20位于中框10的后侧,这适宜于安装人员从中框10的后侧对显示模组进行拼接安装的场景,在这种情况下,第一螺纹紧固件30的一端可以从中框10的后侧依次穿过拼接通孔201并与拼接螺孔101通过螺纹连接紧固连接(参考图3和图6-1、图6-2所示)。
请继续参见图1,在一些示例中装配前区100a至少部分凹陷,这样当拼接片20与之配合时,拼接片20的一部分通过该凹陷得以嵌入到装配前区100a中,可以减小拼接片与中框10配合后的总体厚度,避免中框10前侧的拼接片外凸太高,影响显示模组在中框10前侧的安装。在一些示例中,装配前区100a的凹陷深度大于等于拼接片20的厚度,可以保证拼接片20不会外凸于中框10的前侧。应当理解的是,无论如何,拼接片20并不会完全嵌入到一个中框10中,因为一个拼接片至少要同时与两个中框10配合,因此其嵌入每一个中框10的只会是其自身的一部分,同时也总有一部分外露于该中框10。不过从拼接片20的厚度方向上来说,其嵌入部分可以完全嵌入中框10。
请继续参见图1至图3,在一些示例中,中框10的拼接片装配区中设置有定位销孔102,定位销孔102用于与拼接片20上的定位销钉202配合。可以理解的是,孔销配合简单、无需工具,易于实现,当将拼接片20与中框10上的拼接片装配区100贴合时,定位销孔102与定位销钉202就已经完成了孔销配合,也即定位销钉202已经插入了定位销孔102中,此时,第一螺纹紧固件30尚未与拼接螺孔101以及拼接通孔201完成配合,因此通过孔销配合可以在正式对中框10与拼接片20进行锁定之前先实现拼接片20在装配连接区100上的初步固定或者说“预固定”。在孔销配合实现以后,拼接通孔201与拼接螺孔101会对齐,这也为第一螺纹紧固件30与拼接片20和中框10的配合提供了便利条件。本实施例中,孔销配合的配合精度高于螺纹配合的配合精度,例如,本实施例中,定位销孔102与定位销钉20之间的间隙为0.15mm,而第一螺纹紧固件30与拼接螺孔101之间的配合间隙为0.5mm。由于第一螺纹紧固件30与拼接螺孔101的作用在于从第一螺纹紧固件30的轴向上锁紧拼接片20与中框,所以在装配精度方面可以低于定位销孔102与定位销钉20之间的配合精度,使得在装配的时候,第一螺纹紧固件30更便于拧入拼接螺孔101,便于快速安装。
在一些示例中,拼接片20中片体与定位销钉202可以一体成型,例如通过压铸一体成型,可以理解的是,通过一体成型的工艺形成拼接片20,可以显著增强拼接片20的品质,例如,在一种示例中,定位销钉202与片体一体成型,并且定位销钉202的直径达到8mm以上,这样可以保证片体与定位销钉202承受500公斤以上的压力。
本实施例中设置在拼接片装配区100上的定位销孔102可以为盲孔,也可以为贯穿孔,如果为盲孔,则装配前区100a与装配后区100b各自对应的定位销孔102必然是相互独立的;如果定位销孔102为贯穿孔,也即装配前区和装配后区的对应的定位销孔相通,则装配前区100a与装配后区100b各自对应的定位销孔102可以是相同的。在一些示例中,为了减少拼接片装配区100上的开孔数量,维护拼接片装配区100的承重能力,可设置装配前区100a与装配后区100b共用一个定位销孔102,在这种情况下,定位销孔102朝向中框10前侧的一端可供定位销钉202自中框10前侧插入,另一端可供定位销钉202自中框10的后侧插入。
请继续参见图1和图2,在一些示例中,装配前区100a与其所在的顶角区域对应的矩形顶点之间设有顶角凸起103,对应地,在与该装配前区100配合的拼接片20中,设有供顶角凸起103穿越的第一限位槽203,第一限位槽203贯穿拼接片20,在该拼接片20与装配前区100a配合时,顶角凸起103将穿过拼接片20上的第一限位槽203,如图4所示。例如在图4当中,当拼接片20嵌入到装配前区100a时,顶角凸起103将伸入第一限位槽203,使得拼接片20可以套在四个中框10的顶角凸起203上,从而在平行于显示面的方向上实现相邻中框10间的预固定,这样至少可以保证四个中框10在平行于显示面的方向上不会彼此分离。
另外,因为中框10前侧需要安装显示模组,因此,在装配前区100a向着中框后侧凹陷的情况下,在装配前区100a与其所在的顶角区域对应的矩形顶点之间设顶角凸起103,可以避免中框10 的整个顶角区域均处于凹陷状态从而导致安装在中框10前侧的显示模组的角落区域得不到中框10支撑的问题,通过设置顶角凸起103,可以提升中框10对其前侧的显示模组的支撑能力,提升基于该中框10形成的显示设备或拼接显示屏的显示面的平整度。
需要说明的是,虽然图2中示出的拼接片20中,第一限位槽203的位于拼接片20的中部,其四周均被拼接片20的本体包围,但在本实施例的其他一些示例中,拼接片20还可具有其他结构,例如,在图5示出的另一种拼接片20与第一螺纹紧固件30配合的示意图中,拼接片20的本体并未形成封闭的环形,第一限位槽203并未被拼接片20的本体全包围。可以理解的是,图2示出的拼接片20用于对四个中框10进行拼接,而图5示出的拼接片20则用于对两个中框10进行拼接。在整个拼接后的显示屏中,图2所示的拼接片位于拼接后的显示屏的内侧区域,而图5所示的拼接片20位于拼接后的显示屏的外侧区域。
请继续参见图2与图5,在一些示例中,拼接片20与拼接片装配区100接触的平面为在拼接片20上形成的凸台204的端面,凸台204至少有两个,各凸台204的端面整体位于同一平面,且同一中框10上与凸台204的端面接触的平面也位于同一平面上。当不同的中框10分别与拼接片20上对应的凸台204的端面紧密贴合的情况下,可以保证这些中框10整体处于同一平面上。凸台204的端面为光滑平面,对应的,中框上的与凸台204接触连接的表面也为光滑平面。拼接通孔201设置在凸台204上。除了凸台204的端面为光滑平面外,拼接片20的其他表面可以为相对粗糙的表面以降低制造成本,对应的,除了中框10与凸台204接触的表面外,中框的其他表面也可以为相对粗糙的表面以降低制造成本。在本实施例中,如图3所示,中框后侧的各装配后区100b设有与拼接片20的凸台204对应的凸台106,各凸台106位于同一平面,且也为光滑平面。且各凸台106凸出于中框10的后侧,便于打磨加工,以保证各凸台106位于同一平面。拼接片20上的各凸台204与不同中框背面的凸台106配合可确保多个中框的拼接后的平整度。应当理解的是中框前侧的各装配后区100a也可以设置类似于凸台106的凸台。
为了将中框10拼接形成的拼接显示屏固定在安装支架或墙体等安装载体上,需要将中框10固定到安装载体上,可以理解的是,将中框10固定到安装载体上有两种途径:一种是通过外部固定件直接作用于中框10,实现中框10在支架或墙体等安装载体的固定,另一种是通过外部固定件作用于与中框10固定的拼接片20,利用拼接片20间接实现中框10与安装载体的连接固定。前一途径中一般会在中框10上设置固定孔,后一途径中则在拼接片20上设置固定孔。
请继续结合图1至图6-2,在一些示例中,安装人员选择从中框10的前侧对中框10进行组装拼接并形成拼接显示屏,该安装方式可简称为“前安装”。在这种情况下,安装人员可以先不在中框10的前侧安装显示模组,而是先在中框10的前侧通过安装拼接片20,并通过第一螺纹紧固件30完成拼接片20与中框10的锁定,实现中框10间的拼接;另一方面,安装人员可以利用第二副连接片64(参考图6-2)与第二外部固定件65实现中框10在安装支架(即安装载体)上的安装:将待固定的中框10置于安装支架的前侧,将第二副连接片64置于安装支架的后侧,然后将第二外部固定件65的一端从中框10的前侧伸入设置在中框10顶角区域的外部固定孔104,第二外部固定件65的一端穿过外部固定孔104(参考图4)后伸入第二副连接片64上的第二连接孔中,其中外部固定孔104为通孔(无螺纹),第二连接孔为螺纹孔或通孔,第二外部固定件65可为但不限于螺栓等螺纹紧固件,第二外部固定件65通过第二连接孔螺纹连接固定或通过螺母与第二连接孔连接固定,从而实现安装支架与中框10的固定,完成锁紧之后,中框10与第二副连接片64将安装支架夹在中间。中框10的固定完成之后,安装人员可以从中框10的前侧安装显示模组,从而得到固定在安装支架上的拼接显示屏。还有一种示例中,可以将安装载体由安装支架换成具有承重能力的墙体,在这种情况下,中框10上的外部固定孔104可以与第三固定件配合,第三固定件可以是自攻螺钉或膨胀螺丝等螺纹紧固件,第三固定件的一端穿过中框10上的外部固定孔104后穿入墙体,从而将中框10固定在墙体上。
在一些示例中,外部固定孔104同拼接片装配区100处于相同的顶角区域中,二者可以分布在不同的顶角区域中。在部分示例中,中框10的四个顶角区域均设置有拼接片装配区100与外部固定孔104,在这种情况下,无论是对中框10进行拼接还是将中框10安装到外部墙体或支架上,都不需要对中框10的排布位置进行区分,有利于提升安装人员的操作效率,降低操作负担。
在本实施例中,安装人员选择从中框10的后侧对中框10进行组装拼接并形成拼接显示屏,该安装方式可简称“后安装”。在这种情况下,中框10不再依靠外部固定孔104实现在安装支架上的固定,而是通过在拼接片20上设置具有内螺纹的第三连接孔205,拼接片20一方面实现中框10间的拼接,另一方面通过具有内螺纹的第三连接孔205与外部的第一副连接片62固定,从而实现中框10与第一副连接片62之间的连接:请结合图2和图6-1,首先,安装人员可以在中框10的后侧安装拼接片20,并利用第一螺纹紧固件完成拼接片20与中框10的锁定。然后,将第一外部固定件61(可为但不限于螺纹紧固件)的一端从第一副连接片62的后侧穿过第一副连接片62上的第一连接孔(第一连接孔为通孔,无螺纹),然后与拼接片20上具有内螺纹的第三连接孔205紧固连接,从而完成拼接片20与第一副连接片62的连接固定。在图6-1中,拼接片20与第一副连接片62分别位于安装支架63的前侧与后侧。在后安装方式中,中框10不需要与第一副连接片62连接,不需要在中框10上额外设置与第一副连接片62连接的孔,可简化中框10的结构。
本实施例还提供一种拼接组件,该拼接组件中包括前述任意一种示例中提供的拼接片,同时,该拼接组件中还包括第一螺纹紧固件、第一副连接片、第一外部固定件、第二副连接片和第二外部固定件。其中,拼接片用于对若干(例如两个或4个)中框进行拼接。第一副连接片与第二副连接片则可用于将拼接后的中框(或者说拼接后形成的拼接显示屏)固定在安装载体上。可以理解的是,将拼接后的中框固定在诸如安装支架等安装载体上时,选择使用第一副连接片与第二副连接片中的任意一个即可。例如,如果选择“后安装”方式,则使用第一副连接片,如果选择“前安装”方式,则使用第二副连接片。在“后安装”方式中,第一副连接片通过第一螺纹紧固件与拼接片配合,具体地,第一螺纹紧固件穿过第一副连接片后穿过拼接片上的连接孔。在“前安装”方式中,第二副连接片与中框配合,具体地,第一螺纹紧固件从中框前侧穿过中框上的外部固定孔后,穿过第二副连接片。本实施例所提供的拼接片,支持对中框从前后侧进行拼接,并且拼接片可以通过定位销钉与中框的定位销孔配合,以及拼接片的凸台的端面位于同一平面上并与中框进行紧密贴合,减小了拼缝,提高了拼接平整度;同时,因为中框支持前侧拼接,也支持后侧拼接,安装操作简单,适配场景广。
本实施例提供一种拼接显示屏,包括至少两个拼接在一起的中框,至少两个显示模组以及至少两个后盖;各显示模组分别安装于各中框的前侧,各后盖分别安装于各中框的后侧。
本实施例中的中框可采用但不限于上述各示例中的拼接片拼接在一起。例如参见图7与图8所示,拼接显示屏7中包括拼接片20、至少两个第一螺纹紧固件30以及至少两个中框10。中框10通过第一螺纹紧固件30与拼接片20固定在一起,因此,利用拼接片20作为“桥梁”,可以使得不同的中框10拼接在一起。在一个拼接显示屏7中,可以包括结构不完全相同的两个或两个以上的拼接片20,例如,在图7中,拼接显示屏7中部分拼接片20可以用于对四个中框10进行拼接,另外一些拼接片20可以仅用于对两个中框进行拼接,可以理解的是,一个拼接片20对应至少两个中框10,同时一个中框也可能会与至少两个拼接片20相对应。
在拼接显示屏7中还包括多个显示模组40,显示模组40安装在中框10的前侧,如图8所示。在一些示例中,显示模组40可以通过磁吸、卡接、螺接甚至是粘接等方式可拆卸地固定在中框10上。例如,请进一步参见图9和图13,显示模组40上设置有第一磁吸件411,中框10的前侧设置有第二磁吸件111,第一磁吸件411与第二磁吸件111在显示模组40装配至中框10的状态下位置相对,且二者相互吸引。可以理解的是,第一磁吸件411与第二磁吸件111中的一个可以为磁铁,另外一个可以包括铁磁材质的金属(例如铁、钴、镍),或者两个均为磁铁。
在一些示例中,第二磁吸件111包括连接杆,请参见图10或图12所示的第二磁吸件111,从功能上来说,第二磁吸件111具有磁吸前端111a与固定后端111b,且磁吸前端111a与固定后端111b分别位于连接杆1111的两端,请参见图11,中框10上设置有磁吸件固定孔1110,固定后端111b伸入该磁吸件固定孔1110中,而磁吸前端111a外露于外框10的前侧,用于与显示模组上的第一磁吸件411(参考图9和图13)相互配合。在这里将连接杆1111外露于中框10前侧的高度称为外露高度,本实施例中外露高度可调,也即连接杆1111上磁吸前端111a距中框10的距离可调,这就使得与磁吸前端连接的显示模组40与中框10的距离可调,通过这种设置,可以保证在将中框10拼接形成拼接显示屏后,拼接显示屏上各显示模组40与中框10的距离能够灵活调整,从而能够保证各显示模组的显示面处于同一平面,提升拼接显示屏的整体显示效果。
在本实施例中,磁吸前端111a设置有前操作部,该前操作部被配置为与外部工具(包括螺丝刀、套筒等工具)配合以接受外部工具自中框10的前侧调节连接杆1111的外露高度。所以,如果需要调节某一个显示模组与中框10间的距离时,安装人员可以先拆下该显示模组40,然后利用外部工具对前操作部进行操作,调节结束后再将显示模组40安装回中框10上。在一些示例中,固定后端111b至少部分外露于外框10的后侧,固定后端111b也设置有用于调节连接杆1111外露高度的操作部,其与前操作部对应,被称为“后操作部”,应当明白的是,如果安装人员想要利用后操作部调节连接杆1111的外露高度,则需要从中框10的后侧进行操作,在这种情况下,可以选择不对显示模组40进行拆卸而直接调节,这样也方便安装人员实时确定该显示模组40的显示面与其他显示模组40显示面的差距。由于第二磁吸件111中连接杆1111的外露高度支持从中框10前侧进行调节,也支持从中框10后侧进行调节,便于安装人员根据应用场景灵活选择调整方式来提高显示面的平整度。
在一些示例中,连接杆1111与磁吸件固定孔1110通过螺纹配合,在连接杆1111的表面设置有外螺纹,而在磁吸件固定孔1110的内壁上设置有内螺纹,二者的螺纹相适配,因此连接杆1111可以通过旋转而在磁吸件固定孔1110中沿其轴向移动。在一些示例中,前操作部可以是设置在磁吸前端111a的凹陷图案,和/或,后操作部可以是设置在固定前端111b的凹陷图案,凹陷图案包括但不限于类“一”字图案、类“十”字图案或者是类“*”形、五边形图案、六边形图案等非圆形图案,对应地在外部工具上应该具有能够插入到这类凹陷图案中并且与凹陷图案相适配的端部,例如外部工具可以是螺丝刀(也称起子)。在本实施例的另外一些示例中,前操作部可以是磁吸前端111a端面的非圆形轮廓,和/或后操作部可以是固定后端111b端面的非圆形轮廓,这里所说的非圆形轮廓是指三角形、矩形、平行四边形、正六边形、正八边形等非圆形的形状,对应地,在外部工具上应该具有形状及尺寸能够与这种端面配合的凹孔,例如外部工具可以是套筒。
在一些示例中,请参见图12所示第二磁吸件111除了连接杆1111以外,还可以具有磁吸盘1112,磁吸盘1112固定于连接杆1111靠近磁吸前端111a的一端,其可以与第一磁吸件411相互吸引,所以,在这种情况下,磁吸前端111a实际上就是磁吸盘1112所在的一端,磁吸前端111a的磁吸功能由磁吸盘1112实现。在一些示例中,磁吸盘1112可以为磁铁,磁吸盘1112的外轮廓面积大于连接杆1111靠近磁吸前端111a的端面面积,所以通过磁吸盘1112与第一磁吸件磁吸配合,相较于直接通过连接杆1111的磁吸前端111a与第一磁吸件磁吸配合的情况可以增加第二磁吸件111与第一磁吸件之间彼此相对的面积,提升二者间的相互吸引力,增强显示模组在中框上固定的可靠性。
在一些示例中,磁吸盘1112远离连接杆1111的端面上可以设置有凹陷图案以形成前操作部,包括但不限于类“一”字图案,这些凹陷图案便于安装人员采用起子等拆装工具对磁吸盘1112进行旋转,进而让磁吸盘1112通过旋转带动连接杆1111沿着连接杆1111的轴线运动。在本实施例的另一些示例中,磁吸盘1112的外轮廓可以为正六边形等圆形以外的形状,这样便于安装人员采用套筒等外部工具对磁吸盘1112与中框10表面间的距离进行调节。在本实施例的一种示例中,第二磁吸件111的磁吸前端设置有外轮廓为正六边形的磁吸盘,形成了前操作部,固定后端的端面上设置有可供起子操作的凹陷图案,该凹陷图案形成了后操作部,如图12所示。还有一种示例中,第二磁吸件111的连接杆1111的两端均设置有外轮廓为非圆形的磁吸盘1112,且磁吸盘1112远离连接杆1111的端面上还设置有凹陷图案。
在一些示例中,显示模组可以与中框进行孔销配合,例如请继续参见图9和图13,在中框10的前侧设置有第二孔销连接件112,而在显示模组40的后侧设置有第一孔销连接件412,在图9对应的示例中,第二孔销连接件112可以为销钉,而第一销孔连接件412可以为销孔,可以理解的是,在本实施例的其他一些示例中,第一销孔连接件412与第二孔销连接件112的具体实施方式可以互换。不过,如图9一样将销钉设置在中框10上,显示模组40上则仅设置销孔,这样可以保证显示模组40表面的平整度,便于显示模组40的包装与运输。
在一些示例中,请参见图13所示,显示模组40的背面还设置有固定环413,与固定环413配合的固定绳(未图示)一方面可以系在固定环413上,另一方面可以系在中框上,这样,即便是拼接显示屏所处环境发生地震、飓风等恶劣灾害,显示模组40也不会轻易从中框上脱落(坠落),避免了显示模组40因坠落而损坏,更杜绝了显示模组40坠落伤人的情况,保护了财产与人身安全。
本实施例提供的拼接显示屏中各显示模组40可以通过磁吸的方式设置在中框上,便于拆装,降低了拼接显示屏的拆装负担,有利于提升拼接显示屏的安装效率。同时由于中框上与显示模组配合的第二磁吸件中连接杆的外露高度可调,因此可以在中框拼接完成后保证各显示模组的显示面处于同一平面,提升显示效果。而且,在本实施例中,第二磁吸件中连接杆的外露高度支持从中框前侧进行调节,也支持从中框后侧进行调节,便于安装人员根据拼接显示屏的应用场景灵活选择调整方式来提高显示面的平整度。
在本实施例中,一个中框同与之对应的显示模组也可以形成一个具有显示功能的显示设备(也可称之为显示单元),所以前述实施例中的拼接显示屏也可以被视作由多个显示设备拼接形成。为了便于理解,本实施例中下面从显示设备的层面进行介绍。本实施例中显示设备包括中框以及显示模组,通常一个中框对应两个显示模组,不过本实施例中也并不排除一个中框上安装更少或更多显示模组的情况。在一些示例中,显示设备还包括后盖,请参见图14示出的显示设备8的一种爆炸示意图:后盖50安装在中框10的后侧,用于从中框10后侧对显示设备8中的显示支持模块(本实施例中是指对显示模组的显示进行必要支持的模块包括但不限于电源、信号转接板中的至少一个)以及显示模组40的背面进行遮罩,一方面提升显示设备8的美观性,另一方面也可以起到防潮防尘等作用。
在一些示例中,后盖50可以通过螺接、卡接甚至是粘接等方式固定在中框10上。在本实施例的另外一些示例中,后盖50也可以同显示模组40一样选择以磁吸的方式与中框10配合。例如,请进一步参见图15,在中框10上设置有第四磁吸件114,而在后盖50上设置有与第四磁吸件114相互配合的第三磁吸件511。第三磁吸件511与第四磁吸件114在后盖50装配至中框10的状态下位置相对,且二者相互吸引。可以理解的是,第三磁吸件511与第四磁吸件114中的一个可以为磁铁,另外一个可以包括铁磁材质的金属,或者两个均为磁铁。
在一些示例中,后盖50在中框10上的安装并不会对中框10后侧的装配后区100b造成影响:中框10上存在后盖遮挡区,其是指后盖50安装到中框10上以后中框10上被该后盖遮挡的区域,在本实施例中,后盖遮挡区与中框上的拼接片装配区并不重叠。例如在图6-1或图15对应的示例中,后盖50可以内嵌于中框10,并覆盖中框10的边梁所围合的区域,可以理解的是,后盖50的设置不会遮挡装配后区100b,因此如果在装配后区100b上设置拼接片以实现中框10(或者说显示设备8)的拼接,拼接片也不会干涉后盖50在中框10上的安装。
在一些示例中,后盖50的一侧边设置有外凸的卡舌片,例如在图15中卡舌片512设置在后盖50的底边上,中框10对应的边梁,也即底侧边梁上设置有容纳该卡舌片512的卡舌凹槽1151,卡舌凹槽1151向远离后盖50的方向延伸,卡舌凹槽1151的槽口上方部分区域设有遮挡部1152,遮挡部1152凸出于边梁以在卡舌凹槽1151上方提供容纳空间,该容纳空间供卡舌片512以平行于槽口的方向插入遮挡部1152下方,槽口未被遮挡部1152覆盖的部分以供卡舌片512插入卡舌凹槽1151。卡舌片512可以大致平行于卡舌凹槽1151槽口的方向伸入容纳空间内,并且卡舌凹槽1151的内部空间可供卡舌片512随着后盖50自平行于槽口的状态旋转至垂直于槽口的状态,即卡舌凹槽1151的内部空间可供后盖50带动卡舌片512从垂直于显示设备的显示面的方向旋转至平行于显示面的方向。
在后盖50通过第三磁吸件511与卡舌片512装配到中框10的情况中,后盖50可以从中框10的后侧实现拆装,拆装操作简单易于实现,而且,后盖50上可以不设置与中框10配合的螺孔等,有利于提升后盖50加工效率以及后盖50的完整性。同时,安装后盖50时,可以将后盖50垂直于显示面摆放,并将卡舌片512插入到卡舌凹槽1151中,实现后盖50在中框10上的快速定位;随后再将后盖50旋转至与显示面平行的方位,使得后盖50上的第三磁吸件511准确地吸附到中框10上的第四磁吸件114上,实现后盖的快速安装,这避免了在安装后盖50时手动对第三磁吸件511与第四磁吸件114进行对位的过程,提升了后盖50的安装效率。另一方面卡舌片512插入卡舌凹槽1151后,中框10的边梁、卡舌凹槽1151以及遮挡部1152也能在一定程度上对后盖10进行支撑与限位,这提升了后盖50与中框10连接的可靠性。
在一些示例中,中框10中设有尺寸可供显示模组40在前后两侧穿越的镂空区域113,例如,如果镂空区域113为矩形,则至少该矩形的对角线的尺寸大于显示模组40显示面的短边尺寸,在一些示例中,在镂空区域113为矩形的情况下,镂空区域113的长边尺寸也大于显示模组40显示面的短边尺寸。不过本领域技术人员可以理解的是,由于中框10的顶角区域中设置有拼接片装配区等结构,所以通常情况下,镂空区域113并不是标准的矩形,不过,在这种情况下,镂空区域113轮廓上至少存在两点的连线的长度大于显示模组40显示面的短边尺寸。由于镂空区域113的尺寸可供显示模组40穿越中框10的前后两侧,因此,在将中框10前侧的显示模组40拆卸下来以后,显示模组40可以穿过镂空区域113从而达到中框10的后侧。
在一些示例中,中框10上仅由四个边梁围合形成一个镂空区域113,不过,在本实施例的其他一些示例中,中框10除了包括四个边梁以外,还具有至少一个中间梁,请继续参见图1所示,四个边梁11首尾相连,且这四个边梁11在显示面上的垂直投影的轮廓大致呈矩形。一个中间梁12的两端连接于两个相对的边梁11上,如此,该中间梁12把边梁11围合的区域划分为两个镂空区域113。如果中框内的中间梁不只一个,那么就可以划分出两个以上的镂空区域。在一些示例中,各中间梁相互平行设置,还有一些示例中,各中间梁中也可以存在部分互相垂直,例如,在一种示例中,中框内包括两个相互垂直的中间梁,在这种情况下,中框内就有四个镂空区域,中框整体可以呈类“田”字型。
在本实施例中,显示模组支持从中框的前侧拆装,也支持从中框的后侧拆装。以显示模组的拆卸为例,请结合图14与图15,当显示模组40以磁吸的方式安装在中框10上时,安装人员可以直接从前侧利用吸盘等工具吸下显示模组;或者安装人员先从中框10的后侧拆除后盖50,然后从中框10后侧向显示模组40施加推力,从而使得显示模组40脱离中框10,但与此同时显示模组40并不会脱离安装人员的控制(例如显示模组40依旧被安装人员持握在手中,或者是依旧连接在安装人员控制的拆装工具上),随后,位于中框10后侧的安装人员可以通过旋转显示模组40的朝向并移动显示模组40等方式,使得显示模组40得以穿过中框10上的镂空区域113,实现从中框10后侧完成拆卸的效果。
在一些示例中,为了便于从中框10的后侧拆卸显示模组40,可以在显示模组40的后侧设置有模组持握部,请参见图13和图16示出的显示模组40的一种结构示意图:显示模组40的后侧设置有把手作为模组持握部414,安装人员在从中框的后侧拆装显示模组40时,可以通过持握该模组持握部414进行操作,这样更便于安装人员的操作,相较于不设置模组持握部414的情况,提升了显示模组40在拆卸或安装的过程中的安全性。
在一些示例中,请参见图16,显示设备中的显示支持模块60安装在中框10上,并且位于中框10的后侧。在一些示例中,显示支持模块60安装在中框10的边梁上,还有一些示例中,显示支持模块60安装于中框10的中间梁上。在一些示例中,显示支持模块60也既支持从中框10的前侧进行拆装,也支持从中框10的后侧进行拆装。所以,在一些示例中,显示支持模块60采用双操作端固定件在中框10上进行固定。顾名思义,双操作端固定件具有两个操作端,这两个操作端分别位于中框10的前后两侧,且两个操作端均支持实现显示支持模块60的拆装,例如,双操作端固定件可以是两个端面均具有凹陷图案的螺柱;又例如,双操作端固定件可以是双头螺栓,还有一些示例中,用于固定显示支持模块60的双操作端固定件可以是双头销轴。
下面对显示模组其余结构进行简单说明:请参见图17,显示模组40包括灯板401与底壳402,灯板401上设置有多颗发光芯片组成的芯片阵列,例如LED阵列、Micro-LED(微型发光二极管)阵列、Mini-LED(迷你发光二极管)阵列、OLED(有机发光半导体)阵列中的至少一种。灯板401固定于底壳402的前侧,当显示模组40被安装到中框上后,底壳402的后侧朝向中框的后侧。
应当理解的是,显示模组40的工作需要电流的驱动,同时也需要接收显示控制信号,因此其需要与设置在中框上的显示支持模块60实现电连接与信号连接,所以,在显示模组40设置有与电源对应的电源接口,以及与信号转接板对应的信号接口。对于显示模组40而言,这些接口都属于显示模组40的对外接口,其用于与中框上的模组接口连接。在一些示例中,显示模组40还包括分线板403,例如请继续参见图17所示,分线板403设置于底壳402的后侧,也即底壳402上与灯板40相对的一侧。显示模组40的对外接口设置在分线板403上,在一些示例中,分线板403上仅设置有一组对外接口,这一组对外接口中包括显示模组40实现工作需要外部连接的各种接口。在本实施例的其他一些示例中,分线板上也可包括两组对外接口,例如请参见图13所示:在图13示出的显示模组40中,分线板403上的左侧与右侧都设置有对外接口4030,分别是左侧接口与右侧接口,这样一个显示模组40既支持被安装在中框的左侧,也支持被安装在中框的右侧,安装人员现场安装时不必再对显示模组40的安装位置进行区分,增强了显示模组40的通用性,也提升了显示模组40的安装的效率。
在本实施例一些示例提供的显示设备中,显示支持模块中电源与信号转接板中的至少一个进行了双备份,例如在一种示例中,一个显示设备中同时包括一个主电源以及至少一个备用电源,一个主信号转接板以及至少一个备用信号转接板。可以理解的是,在显示设备中的显示支持模块存在备份的情况下,如果其中某一显示支持模块故障,则显示设备可以切换由对应备份的显示支持模块继续工作,让显示设备继续显示。在这种情况下,若显示设备应用于会议厅,安装人员可以从显示设备的后侧对故障的显示支持模块进行维护,这样维护工作既不会影响会场秩序与会场形象,也不会影响会议的继续进行,有利于提升用户体验。
请继续参见图17与图13,由于灯板401前侧设置了大量的发光芯片,同时灯板401后侧还设置了许多驱动芯片,当灯板401在电流的驱动下工作时,将会产生大量的热,为了避免高热环境影响发光芯片与驱动芯片的性能,需要考虑散热。在一些示例中,在灯板401与底壳402之间设置有导热材料,利用导热材料可以将灯板401上的热量引导至底壳402一侧,并从底壳402散出去。还有一些示例中,底壳402的背离灯板401的一面上设置有多个散热鳍4020,利用散热鳍4020增大了底壳402的表面积,有利于提升底壳402的散热效率。
为了保证底壳402的散热效率,在本实施例中,设置在底壳402背离灯板401一侧的分线板403的表面通常会做的比较小,这样可以避免分线板402对散热鳍4020造成遮挡。另外,为了保证设置在底壳402上的模组持握部414能够外露于分线板403,因此本实施例中分线板403的中部镂空,模组持握部414可以穿过该中部镂空,伸出分线板403。
本实施例提供的显示设备中,显示模组支持从中框的前后两侧拆装,后盖支持从中框后侧拆装,同时,显示支持模块也采用双操作端固定件固定在中框上,所以,显示支持模组也同样支持从中框的前后两侧进行拆装,这方便了安装人员在不同场景下对显示设备中的各部件进行维护,提升了显示设备的维护灵活性与维护效率,降低了维护工作负担。另外因为显示模组的分线板上可以设置两组对外接口,这样增强了显示模组的通用性,提升了显示模组安装效率。同时,因为显示模组中可以在灯板与底壳之间设置导热材料,也可以在底壳后侧设置散热鳍,这些设置增强了显示模组对外的散热能力,提升了显示模组的品质。
本实施例中继续对显示设备进行介绍,请继续参见图14,显示设备8中主要由中框10进行承重,而显示模组40与后盖50则可以几乎不负责承重,因此,在需要搬运显示设备8的情况下,通常是以中框10作为受力主体。一些示例中,为了便于搬运操作,在中框10上设置有提拉把手。例如,请参见图19和图20示出的中框的一种局部结构示意图:提拉把手105(参考图3)设置在中框10的后侧,其被配置为供人持握。一些示例中,为了让安装人员在施力提拉中框10时,中框10可以尽量保持正直的姿态,可以将提拉把手105设置在中框105后侧上部。在一些示例中,提拉把手105设置在中框10后侧被后盖50遮罩的区域内,这样可以保证显示设备8外部的美观性。不过,与此同时,在搬运显示设备8的时候需要突破后盖50对提拉把手105的遮挡,一些情况下,可以选择在搬运显示设备8之前先拆下其后盖50,待搬运至目的地之后再将后盖安装到中框10上,但这给显示设备8的搬运带来了额外负担,增加了显示设备8的应用成本。
在一些示例中,选择在显示设备8的后盖50上与提拉把手105对应的位置开设把手窗,这样可以保证安装人员在不取下后盖50的基础上触及位于中框10上的提拉把手105,不过,在后盖50上开设把手窗会影响到后盖50的完整性,降低后盖50在防潮防尘方面对显示设备8内部的保护能力。
请参见图18与图19,在本实施例的另外一些示例中,后盖50包括后盖本体501与窗挡502,后盖本体501上与提拉把手相对处设置有把手窗5010,所以安装人员的手穿过把手窗5010后可以握到提拉把手上。把手窗5010可以为矩形、梯形或者倒梯形等。在图18与图19中,把手窗5010为倒梯形。窗挡502通过连接件活动连接于后盖本体501,窗挡502在第一状态下可以遮挡把手窗5010,在第二状态下可以外露把手窗5010的至少部分区域。对于具有这种后盖50的显示设备,在有搬运需求时,并不用拆卸后盖50,而是可以直接通过让窗挡502处于第二状态下,从而将手直接从显示设备外部伸入到内部,以握到提拉把手上。而在没有搬运需求时,窗挡502又可以对把手窗进行遮挡,从而对显示设备内部的模块进行保护。
一些示例中,窗挡502可以通过卡接、磁吸等方式连接于后盖本体501上。在本实施例中,窗挡502与后盖本体501可以通过转动连接件连接,请参见图20,图20示出的是图19中Q区域的局部放大示意图:转动连接件503位于后盖50朝向显示模组的一侧,也即转动连接件503位于后盖50的内侧。转动连接件503具有第一连接端5031、第二连接端5032以及转轴5033,第一连接端5031与第二连接端5032均连接于转轴5033,第一连接端5031、第二连接端5032分别与窗挡502、后盖本体501固定连接。在本实施例中,第一连接端5031可以相对于转轴5033转动连接,所以与第一连接端5031固定连接的窗挡502可以相对于转轴5033转动。当后盖本体501安装到中框后侧后,如果安装人员需要使用提拉把手,则其可以通过推动窗挡502,使得窗挡502相对于后盖本体501转动,从而使得窗挡502将其遮挡的后盖本体501上的把手窗5010外露出至少一部分;当没有对提拉把手的使用需求时,可以使得窗挡502回到与后盖本体501处于相同平面的状态。
毫无疑义的是,由于转动连接件503的一个连接端要与窗挡502连接,另一个连接端要与后盖本体501连接,所以,转动连接件503的转轴5033应当设置在把手窗5010的侧边附近,而且转轴5033的轴向应当沿着其所在侧边的走向,例如,在一些示例中,转轴5033的轴向与把手窗5010的上、下侧边平行;还有一些示例中,转轴5033的轴向也可以与把手窗5010的左、右侧边平行。通常情况下把手窗5010的上、下侧边与后盖50的上、下侧边平行,同时提拉把手也平行于后盖50的上、下侧边,这便于搬运人员以手心朝上的姿势将四指伸入后盖50内侧,并顺利握到提拉把手,实现对显示设备的提起操作。
应当明白的是,当转轴5033位于把手窗5010上侧,且沿着把手窗5010的上侧边设置,那么窗挡502在自然状态(没有外力作用的状态)下,就会因为重力的影响而自然遮挡把手窗5010。在这种情况下,当安装人员需要使用把手窗5010时,只需要通过伸手而将窗挡502向中框内顶动,即可使得把手窗5010打开,而当安装人员的手拿出以后,因为外力撤去,所以窗挡502又会自动归位。
在一些示例中,转动连接件503为弹簧合页,弹簧合页的两个合页中一个作为第一连接端5031,另一个作为第二连接端5032,弹簧合页中具有复位弹簧,利用该复位弹簧可以使得两个合页在没有外力作用的情况下自动复位。在这种情况下,无论转轴5033设置把手窗5010的哪一个侧边,都可以实现窗挡502的自动复位。在一些示例中,转轴5033位于把手窗5010的下侧边,且其沿着把手窗5010的下侧边设置,在这种情况下,当安装人员用手顶动窗挡502时,窗挡502将向内向下转动。
请继续结合图20,在本实施例的一些示例,窗挡502包括窗挡本体以及朝向中框的一侧设置的连接楔台5020,窗挡本体为窗挡502的主体,其大体呈片状,连接楔台5020从窗挡本体的表面凸起,其整体呈楔形,并且其凸起高度随着与转轴5033间距离的增大而增大,换言之,在连接楔台5020中,距离转轴5033的距离越大的位置相对与窗挡502表面的凸起高度越高。在连接楔台5020上设置有螺孔,转动连接件503的第一连接端5031通过螺钉固定在该连接楔台5020上,螺钉穿过第一连接端5031上的连接孔后旋入连接楔台5020上的螺孔中。在一些示例中,当窗挡502处于第一状态下时,窗挡502所在的平面与后盖本体501所在的平面重合,应当理解的是,这里所说的“重合”是指后盖本体501所在的平面与窗挡502所在的平面大致重合,而非绝对重合。同时,当窗挡502遮挡把手窗5010时,弹簧合页呈不完全张开状态,也即呈半开状态,从而对窗挡50保持施加一定的预紧力,避免窗挡50松动,进一步保证窗挡50的完整性。
另一方面,连接楔台5020的凸起高度可以为锁定第一连接端5031的螺钉提供足够容纳空间,在一些示例中,设置在连接楔台5020上的螺孔为盲孔,因为连接楔台5020的凸起高度足以让设置其中的螺孔具有足够长度的螺纹以与螺钉配合,实现对螺钉的锁定。在螺孔为盲孔的情况下,螺钉不会穿至窗挡502背向中框的一侧,也即从后盖外侧来看并不会看到窗挡502上连接的螺钉,这样可以提升后盖的美观性。
在一些示例中,后盖50靠近中框顶角区域的位置的厚度可以比其他区域的厚度要薄,请参见图19,本实施例中将后盖50上这种厚度比较薄的区域称为“薄边区”5011。在图19中,后盖50上设置有两个薄边区5011,不过本领域技术人员可以理解的是,在本实施例的其他一些示例中,薄边区5011可以分布于后盖50所有靠近中框顶角区域的位置,在这种情况下,一个后盖50上可以设置四个薄边区5011。由于薄边区5011相较于其他区域厚度更薄,因此这些薄边区5011更易被外力破坏,当安装人员需要后盖50上开孔以供中框内的信号线或电源线从后盖50上出线时,可以直接通过剪切等方式去除薄边区5011,从而在后盖50上形成出线孔。
本实施例提供的显示设备,通过在中框上设置提拉把手,并在后盖上设置与提拉把手相对的把手窗,使得显示设备有被搬运的需求时,安装人员的手可以直接穿过后盖,持握到提拉把手105上。更重要的是,在把手窗上还设置了窗挡502,窗挡在第一状态下对把手窗进行遮挡(可以提升后盖的整体性,增强其美观程度,并保证后盖对显示设备内部器件的保护效果)而在第二状态下可以外露把手窗的至少部分区域,后盖上设置把手窗也极大地方便了安装人员对后盖的拆卸与安装,因为如果没有把手窗,在安装人员在拆装,尤其是拆下后盖时,将难以在后盖上找到合适的着力点,从而导致操作难度大,但设置了把手窗的情况下,安装人员可以将手指伸入把手窗内完成拆装操作,提升了操作的方便程度。
实施例二
对于拼接显示屏,由于其包括至少两个显示模组,为便于各显示模组之间的协同控制,各显示模组的中框之间还需要建立电气连接。现有常规做法是在各中框相邻的侧壁设置通孔,通过通孔使用柔性的电源线接头连接各显示模组的电路,然而柔性的电源线接头没有固定的位置,容易晃动,安装人员需要在中框的狭小空间里双手操作两个中框的电气接口,操作不便,且线路比较杂乱,电源线接头容易磕碰到内部电路引起电路故障。针对该问题,本实施例提供的一种拼接显示屏,其相邻拼接在一起的两个中框本体之间设置有第一电气接口组件和第二电气接口。第一电气接口组件包括可以滑动的第一电气接口,且第一电气接口和第二电气接口的位置固定,第一电气接口和第二电气接口通过活动件的直线滑动而实现对接和分离,安装人员无需在中框侧面的狭小的空间插拔线缆,也避免了电源线接头容易磕碰到内部电路引起电路故障的问题,操作简单方便,线路整齐美观,接口连接的可靠性佳。应当理解的是,本实施例中拼接显示屏所采用的中框、拼接片等结构,可采用上述实施例一所示的结构,也可采用其他结构,也即本实施例提供的拼接显示屏可独立于上述实施例一单独实施;为了便于理解,下面结合附图对其进行示例说明。
参考图21和图22所示,本实施例提供一种拼接显示屏,包括4个显示设备8拼接而成,在其他示例中使用者可根据想要显示的画面尺寸来确定需要多少个显示设备8,但拼接屏至少需要两个显示设备8拼接。故,参考图21至图24,本实施例提供的拼接显示屏至少包括两个相互连接的中框,本实施例中,中框以第一中框110和第二中框120为例,且应当理解的是第一中框110和第二中框120是相对而言的。各中框(第一中框110、第二中框120)的前侧安装有显示模组40,后侧安装有后盖50(本实施例也可称之为背板),各中框(第一中框110、第二中框120)均包括边梁11(本实施例也可称之为侧板),边梁11与后盖50的侧边可固定连接。参考图25至图27所示,第一中框110和第二中框120之间相邻的边梁11上分别设有位置相对应的第一电气通孔151和第二电气通孔152;第一中框110和第二中框120在完成对位拼接后,第一电气通孔151和第二电气通孔152可相互连通。安装于第一中框110上的后盖50上设有第一电气接口组件160,第一电气接口组件160包括支架161和第一电气接口162,支架161包括固定件1611和活动连接于固定件1611的活动件1612,固定件1611固定连接于后盖50,活动件1612受限于在第一方向上相对于固定件1611滑动,活动件1612也位于后盖50的背面侧,第一电气接口162通过第二紧固件连接于活动件1612,第二中框120设有与第一电气接口162相对的第二电气接口171,第二电气接口171固定连接于第二中框120并通过第二电气通孔152外露,第一电气接口162通过活动件1612在第一方向上滑动以通过第一电气通孔151连接第二电气接口171或与第二电气接口171分离。需要将两个中框对接或拆分时,操作人员可以通过直接或间接驱动位于后盖50背面的活动件1612,使第一电气接口162可以沿第一方向上向第二电气接口171滑动(正向滑动,如图29中箭头所示方向)而对接于第二电气接口171,或,第一电气接口162可以向远离第二电气接口171的方向(反向滑动,即与上述正向滑动的方向相反)滑动而脱离第二电气接口171,第一电气接口162和第二电气接口171通过活动件1612的直线滑动而实现对接和分离,安装人员无需在狭小的中框侧面的空间插拔线缆,也避免了电源线接头容易磕碰到内部电路引起电路故障的问题,操作方便,线路整齐美观,接口连接的可靠性佳。
参考图27所示的第一电气接口162未与第二电气接口171连接(即第一电气接口162与第二电气接口171分离)的状态图,以及图29所示的第一电气接口162与第二电气接口171连接的状态图,第一电气接口162伸入于第二中框120(图29未示出)的第二电气接口171内,其可以导通电路,还具有中框间的定位、限位作用。
一些示例中,如图28至图31,第一中框110还包括操作部件180,操作部件180包括转轴181、连杆182和推杆183,转轴181转动连接于后盖50,推杆183连接于活动件1612,连杆182连接转轴181和推杆183,转轴181上设有供第二紧固件安装的通孔,第二紧固件可为内六角螺栓等,以便于锁定转轴181,使第一电气接口162和第二电气接口171保持稳定可靠的连接。转轴181可以转动而驱动活动件1612沿第一方向正向或反向滑动,转轴181连接有连杆182,其可以利用相对较长的力臂,转轴181的转运相对省力,可以方便、可靠地驱动活动件1612沿第一方向正向或反向滑动。操作部件180可以保持装配于第一中框110,也可以作为可拆除的附件工具。
一些示例中,如图28至图31,连杆182上设有把手部184,把手部184为凸出于连杆182的且沿连杆182延伸方向设置的板。把手部184凸出后盖50的背面,以便于操作人员通过把手部184而操作连杆182,使转轴181整体转动,操作方便。
一些示例中,如图28至图30,活动件1612上设有第二限位槽1613,推杆183置于第二限位槽1613内,可便于推杆183对活动件1612施加推力和拉力。
一些示例中,如图28至图30,活动件1612设置有导向槽1614,固定件1611至少有部分位于导向槽1614内,活动件1612在导向槽1614的限位作用下沿第一方向活动,其可以限定活动件1612的最大行程,可以避免第一电气接口162和第二电气接口171对接过紧而导致接口损坏的情况,还可以防止相关线缆被过度拉扯,利于保证结构的稳定性和可靠性。
本实施例中,固定件1611为与后盖一体成型的凸台1611,凸台完全置于导向槽1614内,减小了装配步骤,且结构可靠。
一些示例中,活动件1612上设有定位件190,定位件190设有与后盖50连接的弹性凸起191,定位件190在第一方向上具有第一位置(如图33所示)和第二位置(如图34所示),第一中框110的后盖50设有第一定位孔141和第二定位孔142,定位件190在第一位置和第二位置处分别与第一定位孔141和第二定位孔142配合。如图27和图33所示,定位件190在第一位置与第一定位孔141配合时,第一电气接口162未与第二电气接口171连接。如图29和图34所示,定位件190在第二位置与第二定位孔142配合时,第一电气接口162与第二电气接口171连接。
一些示例中,如图28至图30,固定件1611的顶部还设置有用于防止活动件1612脱离固定件1611的防脱片1615,利于保证结构的可靠性。防脱片1615上设有用于束缚线缆的压板1616,以避免线缆错位、缠绕或受到意外挤压。
一些示例中,第一中框110设有与第一电气接口162电连接的第一电路板,第二中框120设有与所第二电气接口172电连接的第二电路板。第一电路板连接于第一中框110的显示模组40,第二电路板连接于第二中框120的显示模组40。
一些示例中,第一中框110和第二中框120可以相同,均设有第一电气接口组件160和第二电气接口组件170,且第一电气接口组件160和第二电气接口组件170相对设置于中框的顶部和底部,以便于多个中框进行拼接,当然,第一电气接口组件160和第二电气接口组件170也可以相对设置于中框的左侧和右侧。
参考图32所示,定位件190包括中空螺柱192和位于中空螺柱192内的弹簧193和钢珠194,钢珠194有一部分被弹簧193顶出于中空螺柱192的端部,形成凸起191,其可以通过弹簧193、钢珠194的定位结构,使操作人员判断活动件1612是否滑动到位,也可以防止活动件1612随意滑动而导致接口连接松动、失效、异响等问题,结构可靠性更佳。
本实施例所提供的拼接显示屏,需要将两个中框对接或拆分时,操作人员可以通过直接或间接驱动位于后盖50背面的活动件1612,使第一电气接口162可以沿第一方向上向第二电气接口171滑动(正向滑动,如图29中箭头所示方向)而对接于第二电气接口171,或,第一电气接口162可以向远离第二电气接口171的方向(反向滑动,即与上述正向滑动的方向相反)滑动而脱离第二电气接口171,第一电气接口162和第二电气接口171通过活动件1612的直线滑动而实现对接和分离,安装人员无需在狭小的中框侧面的空间插拔线缆,也避免了电源线接头容易磕碰到内部电路引起电路故障的问题,操作方便,线路整齐美观,接口连接的可靠性佳。
实施例三
对于拼接显示屏,为了保证显示的均一性和完整性,在拼接过程中,对安装精度要求是非常高,而一旦需要拼接的显示单元的数量较多时,不同的安装误差叠加起来就可能导致某些位置的显示单元安装位置与预期差距较大从而影响安装效果,甚至无法安装完成。因此,如何在保证安装精度的同时,提升安装的容错率,是亟需解决的问题。针对该问题,本实施例提供了一种中框,应当理解的是,本实施例中的中框可应用于但不限于上述各实施例中所示的拼接显示屏,也可应用于其他拼接显示屏,也即本实施例提供的拼接显示屏可独立于上述各实施例单独实施,在此不对其做限制。
本实施例提供的显示单元的基本组成包括三个部分,分别是显示模组40、中框10以及后盖50,请参考图37和图38。请参考图35,本实施例提供的中框10包括四个边梁11,四个边梁11一体成型围合形成了中框10,而四个边梁11围合的结构中,形成了中框10的镂空区域。对于整个显示模组而言,中框10的最外缘位置也是显示模组40的最边缘,显示模组40的最外缘则最多与中框10齐平,不会比中框10更靠外,这样可以保证中框10对显示模组40的支撑保护。中框的四个边梁11,根据其拼接的位置关系,可以分为位于上方的上边梁、位于下方的下边梁以及位于两侧的侧边梁。为了实现中框10对显示模组40的支撑和保护,中框10上可以设置与显示模组40对应的装配件(装配方式包括但不限于卡扣、磁吸、螺纹紧固、胶粘等,具体的装配方式本申请实施例并不对其进行限定)。
为实现相邻显示模组通过各自的中框10来实现连接,中框10的至少相对设置的边梁11上,其中一个边梁11设置有一组第一固定孔131和贯通边梁11的第一调节孔132,另一者上则设置有至少一与第一固定孔131对应的第二固定孔133,请参考图36。图37示出了相邻中框拼接示意图,在与相邻的显示模组进行装配连接时,也是相应位置的边梁11进行安装连接。在相对设置的边梁11中,其中一个边梁11上设置有一组两个孔,分别是第一固定孔131,和第一调节孔132。第一固定孔131是与相邻显示模组上的第二固定孔133配合,利用第一紧固件139来实现显示模组之间的固定连接的,而第一调节孔132的作用则在于通过第一调节件138对显示模组的位置进行微调节。其中,第一调节孔132包括螺纹孔,第一调节件138包括第一螺纹件,螺纹孔被配置为可供第一螺纹件旋入并伸出后,与相邻中框10的边梁11抵接,以调节相邻中框10之间的间隙。本实施例中第一螺纹件具体可以为螺栓,包括螺帽1381和螺杆1382(即第一螺纹件上非螺帽部),其中螺杆1382的长度大于第一调节孔132的深度,这就使得在第一螺纹件与第一调节孔132连接配合的过程中,允许第一螺纹件正常的伸出该第一调节孔,以便其可以抵接于相邻的中框10的边梁11上。本实施例中第一紧固件139和第一调节件138可以均为螺栓,均设有螺帽,且各螺帽端部设有供操作工具配合的凹陷部(凹陷部的横截面可以为正六边形、一字形、十字形、三角形等等,本实施例并不对其进行限定),可通过对应的操作工具进行拧紧或拧松操作。
第一调节孔132也可被配置为通孔,该通孔贯穿了其所在的边梁11;而且,第一调节孔132是具有内螺纹的螺孔,这样与之对应的第一螺纹件就可以伸进第一调节孔132中,然后通过螺纹的咬合调节第一螺纹件与第一调节孔132之间的相对位置,特别是第一螺纹件相对于第一调节孔132伸出的位置。为了实现上述目的,第一螺纹件的非螺帽部42的长度大于第一调节孔132的深度,这就允许第一螺纹件可以伸出第一调节孔132。而如果第一螺纹件伸出第一调节孔132,那就可以通过第一螺纹件产生顶出作用,让第一螺纹件顶住相邻的显示模组的中框10,从而实现显示模组位置的微调节。该微调节可以为其他的显示模组安装误差提供冗余空间,在其他显示模组安装位置出现偏移之后,通过第一调节孔132配合第一螺纹件可以实现位置纠正。第一螺纹件的非螺帽部所指的是第一螺纹件上除了螺帽部之外的结构,通常是包括设置有螺纹部的柱状结构,其中螺纹部可以在整个柱状结构上均覆盖,或者仅覆盖柱状结构中的一部分,本实施例并不对其进行限定。
在一些示例中,第一螺纹件还可以是螺柱,螺柱的端部外径小于其螺纹部外径。与普通螺栓相比,螺柱不具有尺寸比螺纹部更大的螺帽部,而是具有较为均匀的整体尺寸,其端部的外径比螺纹部的外径更小;这种情况下螺柱的长度可以等于甚至小于第一调节孔132的深度,因为螺柱可以通过下沉的方式深入第一调节孔132中,使得螺柱的底部可以伸出第一调节孔132来抵接相邻的中框10上的边梁11。请参考图39,图39示出了第一螺纹件包括螺柱1383的一种具体的安装结构,由于螺柱1383的端部外径小于螺纹部外径,因此螺柱1383的端部也可以伸入第一调节孔132中,这样即便螺柱1383的长度小于第一调节孔132的深度,也不影响螺柱1383抵接于相邻中框的边梁上;而且图39中示出的螺柱1383的长度比第一调节孔132的深度更短,这样在螺柱1383与第一调节孔132装配之后螺柱1383可以完全没入第一调节孔132中,这使得中框10的外观整体性更好,且不会影响到其他部件的安装。在装配过程中,螺柱1383可以通过与其匹配的操作工具的操作,在第一调节孔132中旋进和旋出,图39中还示出了当螺柱1383端部有内六角凹陷时,其可以通过对应的外六角扳手操作进行旋转。
此外,由多个显示单元拼接形成的大型显示屏通常会应用于室外等条件恶劣的环境,这些环境中往往会出现地面不平的情况;在这种场景下,可以在位于下方的边梁11上设置第一调节孔132,然后利用第一调节件138调节显示模组与地面之间的位置,从而提升显示屏的场地安装稳定性。也就是说,第一调节孔132还被配置为供第一调节件138自中框10外向内贯穿第一调节孔132所在的边梁11,请参考图40。多个中框10拼接过程中,位于最底部的中框10的下边梁并不需要与其他中框的边梁安装匹配,因此对应的第一调节件138也不需要与其他中框的边梁抵接;在这种情况下,为了适配底部的安装环境,即显示设备的架设环境,可以让第一调节件138自外而内的伸入第一调节孔132中,这样可以便于在外侧直接操作第一调节件138,使其可以与承载的基台、地面、支撑架等部件的凹凸度匹配,从而使得整个显示设备摆放平衡,请参考图41,其中A表示显示设备摆放的基台、地面、支撑架等等的承载面。
在一些示例中,第一紧固件139具体可以包括第二螺纹紧固件,第二螺纹紧固件包括一体成型的螺帽部和螺纹部;第一固定孔131和第二固定孔133中,至少一者为通孔,且至少另一者为螺孔,第二螺纹紧固件的螺纹部从通孔穿过后与螺孔配合固定,请参考图36。第二螺纹紧固件的具体类型可以是具有膨大的螺帽部的螺钉或者是螺栓,其螺纹部的外螺纹与螺孔中的内螺纹咬合实现固定连接,而螺帽部则用于第二螺纹紧固件的限位。为了配合第二螺纹紧固件的设置,第一固定孔131和第二固定孔133中,至少有一者是通孔,且另一者是螺孔,这样第二螺纹紧固件就可以穿过通孔,连接到螺孔,从而实现相应的边梁11之间的固定连接。值得一提的是,为了连接的稳定性,在利用第二螺纹紧固件来连接时,还可以设置垫片。
在一些示例中,第一固定孔131和第二固定孔133均为螺孔。当第一固定孔131和第二固定孔133均是螺孔时,第二螺纹紧固件的外螺纹就可以同时与第一固定孔131和第二固定孔133的内螺纹进行咬合实现固定连接,可以有效的提升连接的稳定性。当然,在这种情况下,第一固定孔131和第二固定孔133的螺纹方向应当一致,且与第二螺纹紧固件的螺纹方向匹配。
在一些示例中,第一固定孔131和第二固定孔133均为通孔,第一紧固件139包括第三螺纹紧固件和螺母,第三螺纹紧固件的螺纹部穿过第一固定孔131和第二固定孔133,并与螺母配合固定。除了可以让第三螺纹紧固件与第一固定孔131、第二固定孔133的内螺纹配合连接之外,还可以设置第一固定孔131和第二固定孔133均为通孔,而利用第三螺纹紧固件与螺母的配合,来实现相邻的边梁11之间的固定连接。在这种场景下,第一固定孔131和第二固定孔133均可以是光滑的通孔,其内不必设置内螺纹,通过第三螺纹紧固件直接穿过第一固定孔131和第二固定孔133,在第三螺纹紧固件末端通过螺母咬合实现固定连接,从而可将对应的边梁11连接在一起。
在一些示例中,为了保证安装的可靠性和对称性,同一边梁11上设置的第一固定孔131包括两组,分别设置于边梁11长度方向上的端部。
在一些示例中,同一边梁11上设置的同一组第一固定孔131和第一调节孔132的中心点的连线,垂直于边梁11的长度方向。请参考图35和图36所示,第一固定孔131和第一调节孔132设置的位置相对于边梁11的长度方向而言,是位于边梁11上的同一坐标上,也就是在一定程度上缩小了第一固定孔131和第一调节孔132之间的间距,可以使得第一固定孔131与第一调节孔132之间保持小间距,这样可以减小拼接时的弯曲变形。
在一些示例中,第一固定孔131和第二固定孔133,可以分别设置在上下两个边梁11上,或者是设置在左右两个边梁11上,也就是说,第一固定孔131可以设置于中框的下边梁上;第二固定孔133对应设置于中框的上边梁上;和/或,第一固定孔131设置于中框的任一个侧边梁上;第二固定孔133对应设置于中框的另一个侧边梁上,请参考图42。当设置在上下两个边梁11上时,可以实现与上下两个方位设置的中框10之间的连接;而设置在左右两个边梁11上,则可以实现与左右两个方位设置的显示模组之间的连接。具体的,由于显示设备的拼接过程都是从下而上的拼接,也就是先把位于下方的显示模组设置在对应的位置,然后再在已设置的显示模组上方增设显示模组,将上下相邻的显示模组连接起来;因此,为了连接的简便,在设置第一固定孔131和第二固定孔133的方案中,优选为第一固定孔131设置在中框中的下边梁上,而第二固定孔133则对应设置于中框的上边梁上。在这种结构下,当位于下方的显示模组安装之后,其上边梁的第二固定孔133开放式位于上方,而即将叠放于其上的显示模组,其下边梁的第一固定孔131位置与第二固定孔133对应叠放,然后对应的第一紧固件139,从第一固定孔131伸入,穿过第一固定孔131后与第二固定孔133配合连接,从而实现显示模组的叠放固定;如果有调节的需求,则第一调节件138可以旋入第一调节孔132中实现螺纹配合,然后第一螺纹件(即第一调节件138)的底部伸出位于上方的显示模组的下边梁底部,顶到位于下方的显示模组的上边梁上,可以增大两个显示模组之间的间隙,从而实现相对位置调节。
在一些示例中,根据第一固定孔131的设置位置的不同,对应的第一调节孔132则与之对应设置;具体的,第一调节孔132设置于第一固定孔131所在的下边梁11上,且第一调节件138从第一调节孔132中,自中框10内向外贯穿下边梁11;和/或,第一调节孔132设置于第一固定孔131所在的侧边梁11上,且第一调节件138从第一调节孔132中,自中框10内向外贯穿侧边梁11,具体请参考图43所示。
在一些示例中,为了提升调节的灵活度,还可以包括第二调节孔137,第二调节孔137设置第二固定孔133所在的边梁11上,且第二调节孔137与第一调节孔132错位设置,请参考图44。除了在第一固定孔131所在的边梁11上设置第一调节孔132之外,还可以在第二固定孔133所在的边梁11上设置第二调节孔137,然后通过第二调节孔137进行调节。为了防止第一调节孔132和第二调节孔137发生干涉,第二调节孔137设置位置与第一调节孔132错开;当第二调节孔设置在上边梁11上时,第二调节孔137对应的第二调节件是从下而上的贯穿上边梁11,在调节的过程中,第二调节件贯穿下边梁11后,抵接在位于上方的中框的下边梁11上;和/或,当第二调节孔设置在侧边梁11上时,第二调节孔137对应的第二调节件是从内而外的贯穿侧边梁11,在调节的过程中,第二调节件贯穿侧边梁11后,抵接在位于侧边的中框的侧边梁11上。
可见本实施例提供的中框,可通过在中框10的边梁11上设置第一固定孔和第二固定孔来实现两个显示模组之间的拼接安装,再通过第一调节孔与第一调节件来实现显示模组之间的相对位置调节,从而提升了显示模组的安装容错率,从而保证了大屏拼接显示屏的显示效果。
在一些示例中,至少一个边梁11上设置有过线孔134。过线孔134的设置可以使得被边梁11围合形成的镂空区域与外界可以连通,这样可以实现线路的走线,从而可以在保证显示模组的一体性的前提下连通内外。过线孔134可以设置在任一边梁11上,可以在一个或者多个边梁11上设置,且同一边梁11上可以设置一个或者多个过线孔134,请参考图35。
在一些示例中,请继续参考图45,在一些示例中,至少一个边梁11上可以设置有防撞凸起135,防撞凸起135自边梁11的外表面向外延伸,至少一个边梁11上还可以设置有防撞凹槽136,防撞凹槽136自边梁11的外表面向内凹陷,并与相邻设置的其他显示模组上的边梁11上的防撞凸起135匹配。与设置防撞凸起135对应的,还可以设置防撞凹槽136,从而与其他显示模组的边梁11上的防撞凸起135匹配;此外,防撞凸起135和防撞凹槽136可以设置在同一边梁11上,相应的防撞凸起135和防撞凹槽136也相应的设置在其他显示模组的同一边梁11上,可以进一步提升咬合的稳定性,可以提升显示模组之间连接的稳定性,从而保证组成的拼接显示单元的结构可靠性。
本实施例提供的拼接显示屏,包括至少两组显示单元;其中,相邻的显示单元通过相邻的边梁上的第一固定孔和第二固定孔配合第一紧固件实现固定连接,可以实现显示单元组之间的相对位置调节,从而提升了显示单元的安装容错率,从而保证拼接显示屏的显示效果。
实施例四
在显示模组、平面灯具等显示或照明领域的应用中,均会应用到灯板。而为了对灯板进行支撑和固定,通常需要利用支撑件等刚性部件,对灯板进行固定,该固定可以保证灯板的平整度,也可以提升灯板在装配之后的强度。在现有技术中,其通常做法是在灯板的安装面上,通过焊接的方式,将若干设置有内螺纹的螺孔柱与灯板固定连接,然后再通过设置有外螺纹的螺纹件将支撑件固定到灯板上以实现支撑件与灯板之间的固定连接,这种连接方式最大的弊端在于,采用焊接的方式,容易导致灯板局部受热变形,且焊料一旦固定之后,如果位置错误难以修正,从而大大增加了灯板的加工精度要求,导致灯板组件的加工成本居高不下,且生产效率低。针对该问题,本实施例提供了一种灯板组件及其装配方法,在保证装配可靠性的前提下出错率大大降低,且生产效率也得到了提升。且本实施例提供的灯板组件可应用于上述各实施例中所示的显示模组,也可应用于其他显示模组、平面灯具等。也即本实施例提供的灯板组件可独立于上述各实施例单独实施,在此不对其做限制。
请参考图46至图49和图50a所示,本实施例提供的灯板组件9包括:支撑件93,灯板90和连接组件97;连接组件97包括第一连接件98与第二连接件99,支撑件93具有用于与灯板90连接的第一面931和与第一面931相对的第二面932;灯板90具有用于与支撑件93连接的第三面901和与第三面901相对的第四面902;支撑件93上设置有贯穿支撑件93的第一面931和第二面932的安装孔94;第一连接件98穿过安装孔94并与第二连接件99可拆卸地固定连接(可拆卸,即可以通过工具或徒手拆卸;固定连接,即第一连接件98和第二连接件99与安装孔之间不存在松动的情况),第二连接件99安装在第一面931上;第三面901上与第二连接件99位置对应处设有粘接胶92;粘接胶92将第二连接件99粘接在灯板90的第三面901,且支撑件93与粘接胶92不接触.避免在组装灯板组件9的过程中,粘接胶92与支撑件93粘接,导致拆卸困难;
本实施例提供的灯板组件,采用粘接胶92连接第二连接件99,可避免现有技术中采用的焊接工艺导致灯板局部受热变形,且粘接胶92相比于焊料,容易维修,即便某个第二连接件99粘接位置出错了,也很容易修正。
本实施例中的灯板组件9根据灯板组件9的类型,可以包括显示型灯板或者是照明型灯板;显示型灯板具体可以包括直下式背光灯板,或者是LED直显灯板。其中,灯板90上设置的光源包括多个阵列设置于发光面(本实施例中发光面为灯板90的第四面902,参考图51所示)的发光芯片,发光芯片通常以横纵方式等间隔的排列,也就是横向的每两颗相邻的发光芯片的间距相等,纵向的每两颗相邻的发光芯片的间距相等。根据加工工艺的不同,灯板90上发光芯片的固晶可以在灯板90与支撑件93装配之前或之后。
其中,支撑件93(也可以称为底壳)的材质是刚性的,其具有比较稳定的形态,不易发生弹性或非弹性的形变,比如说可以是包括合金在内的金属,或者是硬质塑料;支撑件93的形态通常是基于灯板的尺寸匹配的一体式结构,比如说支撑件93可以是与灯板90尺寸相仿的一体式支撑板,或者是具有轮廓的壳体结构,该轮廓可以设置为与灯板组件9所需装配的显示器相匹配;另外,基于轻便或者是成本等因素的考量,支撑件93也可以是由若干加强筋组成的框架结构,只要满足灯板组件9具体的应用场景所需的条件即可。灯板90与支撑件93之间的固定连接则通过本实施例中的灯板组件的装配方法实现。
本实施例中的灯板90的具体结构可以包括线路板或各种基板,以及设于线路板或各种基板上的若干发光芯片。安装孔94设置目的是为了让连接组件97可以基于该安装孔94来实现与支撑件93之间的预先连接。本实施例中,支撑件93上设置的安装孔94通常是阵列式排布的,也就是规律性的设置在支撑件93上;一般而言连接组件97的数量与安装孔的数量一致,在强度允许的情况下也可以设置连接组件97的数量少于安装孔94,也就是支撑件93上并非所有安装孔94都会用于连接组件的固定。
其中连接组件97与支撑件93之间的固定是可拆卸的。为了实现该可拆卸式连接,连接组件97包括两个部件,分别是第一连接件98和第二连接件99,第一连接件98和第二连接件99可以穿过通孔来实现与支撑件93之间的连接,这表示第一连接件98、第二连接件99以及支撑件93三者之间会形成一个可拆卸的固定连接。而基于该可拆卸连接,一旦将该连接拆卸,那么就可以实现支撑件93与灯板90在装配之后的分离,该分离操作并不会破坏连接组件97与灯板90之间的粘接结构。本实施例中,第一连接件98和第二连接件99基于安装孔94实现可拆卸式连接。该可拆卸式连接的具体实现形式包括但不限于卡扣连接、榫卯连接、螺纹配合连接等等。
在一些可选实施例中,参考如图48和图49所示,以螺纹配合连接为例,第一连接件98包括设置有外螺纹的第二螺纹件,第二连接件99包括设置有内螺纹的螺孔柱,第二螺纹件与螺孔柱通过内外螺纹配合实现可拆卸连接。第二螺纹件位于支撑件93的上表面侧,其设置有外螺纹的螺纹部可以穿过支撑件93上的安装孔94;螺孔柱则位于支撑件93的下表面侧,第二螺纹件的外螺纹就可以伸入螺孔柱的内螺纹中,通过内外螺纹配合实现第二螺纹件与螺孔柱之间的可拆卸的固定连接,而螺孔柱的底部则通过粘接胶92与灯板90进行粘接,这样在后续灯板90与支撑件93的装配完成之后,通过对第二螺纹件和螺孔柱之间的螺纹配合进行拆卸,就可以将灯板90与支撑件93进行分离,请参考图49为装配后灯板组件的拆卸示意图。
在一些示例中,请参考图48,为了提升螺孔柱与灯板90之间粘接的可靠性,螺孔柱具体可以包括一体成型的螺孔部991和底座992,底座992相比于螺孔部991更靠近灯板90,且底座992封闭螺孔柱的底部,避免粘接胶92与第二螺纹件接触,且底座992的底面积大于螺孔部991的底面,以增加底座992与粘接胶92的接触面,增强螺孔柱与灯板90的第三面901的结合力。本实施例中,螺孔部991呈圆柱状,底座992的形状为圆形,底座的外径大于螺孔部991的外径。在别的实施例中,底座的形状也可以为正方形或椭圆形等其他形状。
参考图50a所示,本实施例中,为了实现灯板组件的装配,本实施例可预先在支撑件93上安装连接组件97,为了便于连接组件97固定到支撑件93上,第二连接件99(本实施例为螺孔柱)与第一连接件98(本实施例为第二螺纹件)连接的部分,至少有一部分嵌入安装孔94,即安装孔94朝向第一连接件98的部分,可容纳第一连接件98的一部分伸入,安装孔94朝向第二连接件99的部分可容置部分第二连接件99,使得安装孔94对第一连接件98和第二连接件99具有限位作用,方便在支撑件93上安装第二连接件99时预先对第二连接件99预先进行限位,便于与第一连接件98连接,具体就本实施例而言,第一连接件98为第二螺纹件,第二螺纹件具有螺帽部981和螺杆部982,螺帽部981的直径大于螺杆部982;第二连接件99为螺孔柱,安装孔94为阶梯孔,其中,安装孔94与朝向第二螺纹件的一侧的第一孔径941大于螺杆部982的直径且小于螺帽部981的直径;安装孔94朝向螺孔柱一侧的第一孔径942大于螺孔柱的外径,安装时可先将螺孔柱的一部分嵌入安装孔94再将第二螺纹件与螺孔柱连接,第二螺纹件和螺孔柱的安装简单,安装效率高。安装孔94的边缘可设有向朝向灯板90的第一凸部95,第一凸部95可延长安装孔94,且可减少支撑件的用料,可降低成本。本实施例中,第一凸部95可以抵在螺孔柱的底座992上,底座992的面积大于第一凸部95的端部面积,可隔离第一凸部95与粘接胶92,避免第一凸部与粘接胶92连接。连接组件97固定于支撑件93之后,就得到了装配有连接组件97的支撑件93,该支撑件93上各连接组件97相互之间的位置已经相对固定,因此不会出现个别连接件(第一连接件或第二连接件)的位置与其他连接件的位置不匹配的情况。接下来,将灯板90水平放置,灯板90的第三面901(安装面)朝上;将装配有连接组件97的支撑件93至于灯板90的上方。
安装面上设有若干与第二连接件99位置对应的连接区域903,预先在连接区域903设置粘接胶92,为后续将灯板90与支撑件进行粘接做准备。请参考图52,其示出了灯板90的安装面(即第三面901)上设置的各连接区域903示意图,在灯板90安装面上设置的粘接胶92的位置是在各连接区域903上,其中连接区域903的位置与支撑件93上设置的第二连接件99的位置对应。这里所说的连接区域903的位置与第二连接件99的位置对应,所指的并非两者需要完全一致的匹配,事实上而言,在设置粘接胶92时只要能保证各个第二连接件99都能正常的通过粘接胶92与第三面901粘接,且粘接的结果可以满足所需的粘接强度即可,这允许实际粘接时,第二连接件99与连接区域903存在一定的错位。第三面901也就是灯板90与支撑件93之间连接时灯板90上的相应面,其一般与灯板90上的发光面(本实施例为灯板的第四面902,参考图51所示)相对,其中发光面所指的是设置发光芯片的面。灯板90在制作完成之后,其发光面是非常平整的,可以水平朝下放置。
然后将第二连接件99对准粘接胶92并将灯板90的第三面901和支撑件93的第一面931压合,使第二连接件99与粘接胶92粘接且支撑件93与粘接胶92不接触。各第二连接件99通过粘接胶92粘接于连接区域903。待粘接胶92固化后可形成所需的灯板组件。由于支撑件93与连接组件97之间是可拆卸的,因此粘接胶92固化后,灯板90与支撑件93之间也可拆卸,以将支撑件93与灯板90分离。
本实施例中,为了在压合过程中,为了使得第二连接件99与灯板90之间留出一定的间隙以容置粘接胶92,支撑件93上设有朝向灯板90的第二凸部96,第二凸部96为支撑件93最靠近灯板90的部分,第二凸部96到灯板90的距离大于第二连接件99到灯板90的距离。在本实施例中,第二凸部96与灯板90接触;在别的实施例中第二凸部96与灯板90之间还可以设置垫片等其他零件。在本实施例中第二凸部96呈条状设置,且有多条,设于支撑件93的边缘和中间部分,使得第一凸部95作用在灯板90上的力相对均匀,且第二凸部96可围合灯板的边缘,可对于灯板的边缘部分提供防尘保护。在的实施例中,第二凸部96也可以呈柱状(例如圆柱状或棱柱状),分散在支撑件93的第一面931上(即各第二凸部之间形成有供空气流通的间隙),使得支撑件93与灯板90之间有更多的空间,有利于灯板90的散热,由于第二凸部96是最靠近灯板90的部分,所以在压合灯板90与支撑件93时,第二凸部96可供支撑点,避免第二连接件99过度挤压粘接胶92,使得粘接胶92有一定的厚度,保障粘接胶92与灯板90和第二连接件的粘接强度,且可减少溢出到第二连接件99外围的粘接胶。由于粘接胶92具有一定的容置空间且粘接胶92具有良好的可塑性,即使第二连接件的底部或连接区域不平整,也不会影响第二连接件99与第一连接件98连接的准确性,只要第一连接件98与第二连接件99预先连接的位置和姿态是正确的,粘接胶92固化后即可保持第一连接件98与第二连接件99的连接的准确性,所以粘接胶92的可塑性降低了粘接过程中的出错率。
在另一种实施例中,如图50b所示,也可以将灯板90的第三面901(安装面)朝下;将装配有连接组件97的支撑件93置于灯板90的下方。支撑件93的第一面931水平放置,然后预先在第二连接件99的底部设置粘接胶92,再将灯板90与支撑件93压合。待粘接胶92固化后也可以得到灯板组件9。设置粘接胶92的目的是粘接灯板90与支撑件93,而为了保持灯板90的平整度,本实施例中所设置的粘接胶92是具有一定厚度的粘接胶92;这种结构下可以通过粘接胶92本身的厚度,适应不同姿态的第二连接件与安装面之间的粘接,而不影响到灯板90的平整度。具体而言,可设置的粘接胶92的厚度大于等于第一预设阈值,可使得在装配时支撑件93上的第二连接件99可以充分的与粘接胶92接触,这种情况下即便第二连接件99出现了倾斜,或者是第二连接件99与对应的预设安装区域位置有错位,都可以通过粘接胶正常地与第二连接件99进行粘接,且粘接之后,所有的第二连接件99之间的相对位置都是固定的。
在一些示例中,为了降低粘接胶92设置过多而导致粘接胶92随处溢出,在第三面901的各预设连接区域903上设置粘接胶92时,粘接胶92的厚度可以设置为小于等于第二预设阈值。其中第二预设阈值大于第一预设阈值,设置粘接胶92的厚度上限值是为了避免涂覆过多的粘接胶92从而导致在粘接时大量的粘接胶92从预设连接区域903溢出,影响到灯板90的其他器件的功能。除此之外,除了可以设置粘接胶92的厚度上限之外,为了降低溢胶的可能性,可以在连接区域903设置第一容胶槽904(参考图50b),也就是在连接区域903的底部设置一些凹陷以承载粘接胶92且限制粘接胶92的流动,且第一容胶槽904使得粘接胶92可以具有一定的厚度,可增强粘接胶92与灯板90和第二连接件99的粘接力;为了降低溢胶的可能性,还可以在第二连接件99的底部设置第二容胶槽993(参考图50a和图51),也就是在第二连接件99的底部设置一些凹陷,使得多余的粘接胶92可以置于凹陷中而减少粘接胶92随着第二连接件99的挤压向外溢出。其中凹陷的形状可以是“一”字形、“十”字形、圆形、椭圆形、波浪形、点阵形等形状中的一种,凹陷还可以增加粘接胶92与第二连接件99的结合表面,以增强粘接胶92与灯板90和第二连接件99的粘接力。
本实施例还提供了一种灯板组件装配方法,通过该灯板组件装配方法制作得到的灯板组件可以大大降低灯板组件装配的出错率,降低灯板组件的生产成本,并提升了生产效率。该灯板组件装配方法也可以用于装配上述灯板组件,为了便于理解,本实施例下面对灯板组件装配方法进行示例说明。该方法包括以下步骤:
S101:参考图46至图49,提供支撑件93、灯板90和连接组件97,连接组件97包括第一连接件98与第二连接件99,支撑件93具有相对的第一面931和第二面932;灯板90具有相对的第三面901和第四面902;支撑件93上设置有贯穿支撑件的第一面931和第二面932的安装孔94。
S102:参考图50a,预先将第一连接件98穿过安装孔94并与第二连接件99可拆卸固定连接,第二连接件99安装在第一面931。
本步骤将与安装孔94对应的连接组件97可拆卸式固定于支撑件93上;连接组件97包括设置于支撑件93相对两个表面其中一个表面的第一连接件98,以及设置于另一表面的第二连接件99;第一连接件98、第二连接件99以及支撑件93基于安装孔94可拆卸式固定连接;
参考图50a和图50b,预先在第三面901上设置与第二连接件99位置对应的粘接胶92,或在第二连接件99上设置粘接胶92;
在本步骤中由于灯板90的第三面901上与第二连接件99位置对应的各连接区域903上或第二连接件99上预先设置了粘接胶92,使得灯板90与支撑件93的第二连接件99可通过粘接胶92粘接连接。本步骤中,优选粘接胶92的厚度大于等于第一预设阈值小于第二阈值。
S103:参考图50a和图50b,将灯板的第三面901和支撑件的第一面931压合,使第二连接件99通过粘接胶92与灯板粘接且支撑件93与粘接胶92不接触;
在本步骤中,为了使得压合时减少灯板90和支撑件93的形变,压合时在灯板90的第四面902或支撑件93的第二面932上施加均匀的力。
S104:固化粘接胶92后得到灯板组件(参考图46至图49所示)。
具体地,本步骤中,在粘接胶92固化之后,可将第一连接件98和第二连接件99分离,从而将灯板90从支撑件93拆卸下来,便于维修。
