具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
图1示出了一种显示设备。如图1所示，该显示设备包括前框01和背板02，前框01包括上前框011、下前框012、左前框013以及右前框014。图2示出了该显示设备中前框和背板的连接情况。如图2所示，上前框011、下前框012、左前框013、右前框014均与背板02的边缘相连接，并且上前框011、下前框012、左前框013、右前框014的后壁均通过螺钉03与背板02固定连接。
在上述显示设备中，如图2所示，由于上前框011、下前框012、左前框013、右前框014均是通过螺钉03与背板02相固定，在装配时，操作者需要将连接上前框011、下前框012、左前框013、右前框014与背板02之间的所有螺钉03拧紧才能完成前框01与背板02之间的装配，这样不但需要浪费大量的时间，降低了该显示设备的装配效率，而且还浪费了大量的人力成本，不利于降低显示设备的总成 本。另外，为了实现背板02与上前框011、下前框012、左前框013、右前框014进行螺钉03连接，背板02表面需要设有向背板02内部延伸的螺纹柱021，以与螺钉03螺纹配合，然而螺纹柱021需要占用背板02内部的一定空间，还会挤压背板02内部的光学组件04(例如螺纹柱021会挤压用于承载液晶玻璃041的胶框042的空间)的设置空间，从而影响背板02内部部件的优化布置。
本公开至少一实施例提供一种显示设备的前框组装结构及显示设备，可以提高显示设备在装配前框与背板时的装配效率，节约人力成本。
例如，图3示出了本公开实施例提供的一种显示设备的前框组装结构，如图3所示，该显示设备的前框组装结构包括前框1和背板2，前框1包括四个子前框，四个子前框分别为沿第一方向(例如图中所示的Y方向)排布的第一子前框11和第二子前框12、两个沿第二方向(例如图中所示的X方向)排布的第三子前框13，第二方向垂直于第一方向。如图4所示，第一子前框11以及两个第三子前框13均具有凹槽10，背板2的边缘能够卡入第一子前框11的凹槽10以及两个第三子前框13的凹槽10中。第二子前框12与背板2连接，例如固定连接。如图5和图6所示，相邻的两个子前框通过第一卡接结构3相卡接，例如，第一卡接结构3用于限制相邻的两个子前框至少在第二方向上发生相对移动。
例如，如图7所示，第一子前框11与背板2通过第二卡接结构4相卡接，第二卡接结构4用于限制第一子前框11与背板2至少在第一方向上发生相对移动。
例如，如图3所示，第三子前框13的两端均与第一子前框11、第二子前框12相抵接，以限制第三子前框13在第一方向上相对第一子前框11和第二子前框12移动。
在上述显示设备的前框组装结构，如图4所示，由于背板2的边缘卡入第一子前框11的凹槽10以及两个第三子前框13的凹槽10中，这样实现了第一子前框11以及两个第三子前框13在背板2厚度方向(例如图4所示的Z方向)的限位。如图3所示，由于第二子前框12与背板2固定连接，这样实现了第二子前框12在背板2厚度方向、第一方向以及第二方向三个方向上的限位。如图5和图6所示，由于 相邻的两个子前框之间通过第一卡接结构3卡接，第一卡接结构3可以限制相邻的两个子前框之间在第二方向上发生相对移动，并且第二子前框12已固定与背板2上，这样与第二子前框12相邻的两个第三子前框13实现了在第二方向与背板2相对固定，也就是两个第三子前框13实现了在第二方向上的限位，那么与两个第三子前框13相邻的第一子前框11同样实现了在第二方向上的限位。如图7所示，由于第一子前框11与背板2之间设有第二卡接结构4，第二卡接结构4可以限制第一子前框11与背板2之间在第一方向上发生相对移动，这样通过第二卡接结构4就可以实现第一子前框11在第一方向上的限位。如图3所示，由于第三子前框13的两端均与第一子前框11、第二子前框12相抵接，以限制第三子前框13在第一方向上相对第一子前框11或第二子前框12移动，这样通过第三子前框13的两端均与第一子前框11、第二子前框12相抵接实现了两个第三子前框13在第一方向上的限位。由此，通过以上结构设计实现了四个子前框在背板2厚度方向、第一方向以及第二方向三个方向上的限位，从而使四个子前框与背板2牢固地连接在一起。
本公开实施例提供的显示设备的前框组装结构，第一子前框11、两个第三子前框13均是通过卡接或者抵接的方式实现与背板2的相对固定，这样在装配时，第一子前框11、两个第三子前框13与背板2的连接就无需使用螺钉，直接通过简单的卡接或抵接就可以完成装配，无需操作者一个一个地去拧紧螺钉，这样节省了大量的装配时间和人力，有利于提高了装配效率，降低人力成本。另外，由于第一子前框11、两个第三子前框13与背板2的连接没有采用螺钉，这样背板2内部就无需设置螺纹柱，从而可以大大减小对背板2内部空间的占用，可以方便背板2内部部件的优化布置。同时，由于第一子前框11、两个第三子前框13与背板2的连接没有采用螺钉，这样也增加了该显示设备外观上的美感。
在上述实施例中，第一卡接结构3并不唯一，可以为各种类型的可卡接结构。比如，如图5所示，在第一子前框11和第三子前框13之间，第一卡接结构3包括设置于第一子前框11上的第一卡爪31以及开设于第三子前框13上的第一卡槽32，第一卡爪31可伸入到第一卡槽32中，并且第一卡槽32沿第二方向的两侧槽壁均与第一卡爪31相抵接；由于第一卡槽32沿第二方向的两侧槽壁均与第一卡爪31 相抵接，这样可以限制第一子前框11和第三子前框13在第二方向发生相对移动。
例如，如图6所示，在第二子前框12和第三子前框13之间，第一卡接结构3包括设置于第三子前框13上的第一卡爪31以及开设于第二子前框12上的第一卡槽32，第一卡爪31可伸入到第一卡槽32中，并且第一卡槽32沿第二方向的两侧槽壁均与第一卡爪31相抵接。由于第一卡槽32沿第二方向的两侧槽壁均与第一卡爪31相抵接，这样可以限制第二子前框12和第三子前框13在第二方向发生相对移动。
例如，在图5所示的实施例中，第一卡爪31与第一卡槽32的位置也可以对调，也就是第一卡爪31设置于第三子前框13上，第一卡槽32开设于第一子前框11上，这样同样可以达到限制第一子前框11和第三子前框13在第二方向发生相对移动的效果。例如，在图6所示的实施例中，第一卡爪31与第一卡槽32的位置同样也可以对调，也就是第一卡爪31设置于第二子前框12上，第一卡槽32开设于第三子前框13上，这样同样可以达到限制第二子前框12和第三子前框13在第二方向发生相对移动的效果。
例如，在第一子前框11和第三子前框13之间，第一卡爪31、第一卡槽32的设置位置并不唯一。比如，第一卡爪31可以设置于第一子前框11和第三子前框13其中一个的后壁上，第一卡槽32开设于第一子前框11和第三子前框13其中另一个的后壁上。例如，如图5所示，第一卡爪31设置于第一子前框11的后壁上，第一卡槽32可以开设于第三子前框13的后壁上。另外，第一卡爪31也可以设置于第一子前框11和第三子前框13其中一个的前壁上，第一卡槽32也可以开设于第一子前框11和第三子前框13其中另一个的前壁上。相比第一卡爪31、第一卡槽32设置于前壁上，当第一卡爪31、第一卡槽32设置于后壁上时，可以使显示设备在可视面，即显示设备的显示侧没有卡接缝隙，从而使显示设备外观更加美观。
需要说明的是：第一子前框11的前壁是指在背板2的边缘卡入第一子前框11的凹槽10的情况下，第一子前框11中位于背板2前侧的侧壁，例如图4中所示的侧壁a。第一子前框11的后壁是指在背板2的边缘卡入第一子前框11的凹槽10的情况下，第一子前框11 中位于背板2后侧的侧壁，例如图4中所示的侧壁b。第三子前框13的前壁是指在背板2的边缘卡入第三子前框13的凹槽10的情况下，第三子前框13中位于背板2前侧的侧壁，例如图4中所示的侧壁a。第三子前框13的后壁是指在背板2的边缘卡入第三子前框13的凹槽10的情况下，第三子前框13中位于背板2后侧的侧壁，例如图4中所示的侧壁b。背板2的前侧是指背板2靠近显示设备的显示画面的一侧；背板2的后侧是指背板2远离显示设备的显示画面的一侧。
例如，在第二子前框12和第三子前框13之间，第一卡爪31、第一卡槽32的设置位置也不唯一。比如，如图6所示，第一卡爪31可以设置于第一子前框11的后壁上，第一卡槽32开设于第二子前框12上可以与第一卡爪31相卡接的位置上。或者，第一卡爪31也可以设置于第一子前框11的前壁上，第一卡槽32开设于第二子前框12上可以与第一卡爪31相卡接的位置上。相比第一卡爪31设置于第一子前框11的前壁上，当第一卡爪31设置于第一子前框11的后壁上时，可以使显示设备在可视面，即显示设备的显示侧没有卡接缝隙，从而使显示设备外观更加美观。
例如，在其他示例中，第一卡接结构3还可以设计为限制相邻的两个子前框在第二方向上发生相对移动的同时，还可以限制相邻的两个子前框在第一方向上发生相对移动。例如，对第一卡爪31和第一卡槽32的形状进行设计，例如在第一卡爪31的端部增加弯钩结构，相应地在第一卡槽32中开设容纳弯钩的腔，从而第一卡爪31和第一卡槽32相配合还可以限制相邻的两个子前框在第一方向上发生相对移动。本公开的实施例对第一卡接结构3的具体形式不做限定。
例如，第二卡接结构4也不唯一，可以为各种类型的可卡接结构。比如，如图7所示，第二卡接结构4包括设置于背板2上，例如背板2的后侧表面上的第一限位凸起41以及开设于第一子前框11上，例如第一子前框11的后壁上的第一限位槽42。在背板2的边缘卡入第一子前框11的凹槽10中的情况下，第一限位凸起41伸入到第一限位槽42中，并且第一限位槽42沿第一方向的两侧的槽壁均与第一限位凸起41相抵接。由于第一限位槽42沿第一方向的两侧的槽壁均与第一限位凸起41相抵接，这样可以限制第一子前框11与背板2之间在第一方向上的相对移动，也就是实现了第一子前框11在第一方向 上的限位。
当然，第一限位凸起41、第一限位槽42的位置也可以相互对调，也就是第一限位槽42开设于背板2上，例如背板2的后侧表面上，第一限位凸起41设置于第一子前框11上，例如第一子前框11的后壁上。在背板2的边缘卡入第一子前框11的凹槽10中的情况下，第一限位凸起41伸入到第一限位槽42中，并且第一限位槽42沿第一方向的两侧的槽壁均与第一限位凸起41相抵接。这样同样可以达到限制第一子前框11与背板2之间在第一方向上的相对移动的效果。
例如，在第一限位槽42开设于第一子前框11的后壁上，第一限位凸起41设置在背板2的后侧表面上的实施例中，为了方便在背板2的边缘卡入第一子前框11的凹槽10的过程中实现第一限位凸起41与第一限位槽42卡接，如图7和图8所示，第一限位槽42包括第一限位槽段421和第一导向槽段422，第一限位槽段421沿第二方向延伸，第一导向槽段422的第一端与第一限位槽段421的一端相连接，第一导向槽段422的第二端延伸至第一子前框11的后壁的第一边沿111，第一边沿111为第一子前框11的后壁靠近第一子前框11的凹槽10槽口的一侧边沿。由于第一导向槽段422的第二端延伸至第一子前框11的后壁的第一边沿111，这样在背板2的边缘卡入第一子前框11的凹槽10的过程中，设置在背板2后侧表面上的第一限位凸起41就可以在第一子前框11的后壁的第一边沿111处沿着第一导向槽段422滑入至第一限位槽段421中，然后在沿第二方向推动第一子前框11，使第一限位凸起41与第一限位槽段421的另一端(例如图7中的c端)相抵接，最终实现第一子前框11在第一方向的限位。由此，通过设置第一限位槽段421和第一导向槽段422，可以避免在第一子前框11与背板2的装配过程中第一限位凸起41与背板2的边沿相干涉，从而使第一子前框11与背板2的装配更加方便顺利。
例如，在第一限位槽42开设于背板2后侧表面上，第一限位凸起41设置在第一子前框11的后壁上的实施例中，为了方便在背板2的边缘卡入第一子前框11的凹槽10的过程中实现第一限位凸起41与第一限位槽42卡接，第一限位槽42包括第一限位槽段421和第一导向槽段422，第一限位槽段421沿第二方向延伸，第一导向槽段422的第一端与第一限位槽段421的一端相连接，第一导向槽段422的第 二端延伸至背板2的后侧表面的边沿。在该实施例中，设置第一限位槽段421和第一导向槽段422所取得的有益效果与第一限位槽42开设于第一子前框11的后壁上的实施例中相同，在此不再赘述。
例如，在其他示例中，第二卡接结构4也可以设计为限制第一子前框11与背板2在第一方向上的相对移动的同时，还可以限制第一子前框11与背板2在第二方向上的相对移动。例如，可以对第一限位凸起41和第一限位槽段421的形状进行设计，例如在第一限位凸起41的端部增加弯钩结构，相应地在第一限位槽段421中开设容纳弯钩的腔，从而第一限位凸起41和第一限位槽段421相配合还可以限制第一子前框11与背板2在第二方向上的相对移动。本公开的实施例对第二卡接结构4的具体形式不做限定。
例如，在本公开实施例提供的显示设备的前框组装结构中，如图5和图6所示，第三子前框13是通过第一卡接结构3与相邻的第一子前框11、第二子前框12实现卡接，从而实现了第三子前框13在第二方向上的限位。第一卡接结构3是在两端对第三子前框13在第二方向上进行限位的。对于大屏幕的显示设备来说，前框1的尺寸通常也比较大，第三子前框13的长度通常比较长，在只通过第一卡接结构3在两端对第三子前框13进行限位的情况下，第三子前框13的中间的部分可能会发生变形，而第三子前框13的中间的部分的变形容易对背板2内光学组件的固定造成了一定的影响。例如，如图4所示，第三子前框13的前壁是对显示设备的液晶玻璃屏进行卡接固定，如果第三子前框13的中间部位发生变形，该变形会造成液晶玻璃屏的固定不牢，从而不利于提高显示设备的品质。
为了解决第三子前框13中间部位可能产生变形的问题，如图7所示，第三子前框13的中部与背板2通过第三卡接结构5相卡接，第三卡接结构5可以限制第三子前框13的中部与背板2在第二方向上发生相对移动。例如，第三子前框13的中部与背板2可以通过多个第三卡接结构5相卡接。其中，第三子前框13的中部是指除去第三子前框13两端之外的区域。例如，多个第三卡接结构5可以在第三子前框13两端之间的区域内均匀分布。通过设置第三卡接结构5，可以限制第三子前框13的中部与背板2在第二方向上发生相对移动，也就是实现的第三子前框13的中部的限位，从而避免第三子前框13 的中部产生变形，避免第三子前框13的中部的变形对背板2内光学组件的固定所造成的影响，从而有利于提高显示设备的品质。
与第二卡接结构4相类似，第三卡接结构5也不唯一。比如，如图7所示，第三卡接结构5包括设置于背板2上，例如背板2的后侧表面上的第二限位凸起51以及开设于第三子前框13上，例如第三子前框13的后壁上的第二限位槽52。在背板2的边缘卡入第三子前框13的凹槽10中的情况下，第二限位凸起51伸入到第二限位槽52中，并且第二限位槽52沿第二方向的两侧的槽壁均与第二限位凸起51相抵接。由于第二限位槽52沿第二方向的两侧的槽壁均与第二限位凸起51相抵接，这样可以限制第三子前框13与背板2之间在第二方向上的相对移动，也就是实现了第三子前框13在第二方向上的限位。
当然，第二限位凸起51、第二限位槽52的位置也可以相互对调，也就是第二限位槽52开设于背板2上，例如背板2的后侧表面上，第二限位凸起51设置于第三子前框13上，例如第三子前框13的后壁上。在背板2的边缘卡入第三子前框13的凹槽10中的情况下，第二限位凸起51伸入到第二限位槽52中，并且第二限位槽52沿第二方向的两侧的槽壁均与第二限位凸起51相抵接。这样同样可以达到限制第三子前框13与背板2之间在第二方向上的相对移动的效果。
例如，在第二限位槽52开设于第三子前框13的后壁上，第二限位凸起51设置在背板2的后侧表面上的实施例中，为了方便在背板2的边缘卡入第三子前框13的凹槽10的过程中实现第二限位凸起51与第二限位槽52卡接，如图7所示，第二限位槽52包括第二限位槽段521和第二导向槽段522，第二限位槽段521沿第一方向延伸，第二导向槽段522的第一端与第二限位槽段521靠近第一子前框11的一端相连接，第二导向槽段522的第二端延伸至第三子前框13的后壁的第二边沿131，第二边沿131为第三子前框13的后壁靠近第三子前框13的凹槽10槽口的一侧边沿。由于第二导向槽段522的第二端延伸至第三子前框13的后壁的第二边沿131，这样在背板2的边缘卡入第三子前框13的凹槽10的过程中，设置在背板2后侧表面上的第二限位凸起51就可以在第三子前框13的后壁的第二边沿131处沿着第二导向槽段522滑入至第二限位槽段521中，然后在沿第一方向，并且向靠近第一子前框11的方向推动第三子前框13，使第二限 位凸起51与第二限位槽段521远离第一子前框11的一端相抵接，最终实现第三子前框13的中部在第二方向的限位。通过设置第二限位槽段521和第二导向槽段522，可以避免在第三子前框13与背板2的装配过程中第二限位凸起51与背板2的边沿相干涉，从而使第二子前框12与背板2的装配更加方便顺利。
需要说明的是，如图7所示，第二导向槽段522的第一端之所以与第二限位槽段521靠近第一子前框11的一端相连接，这是由于在第三子前框13在与背板2的装配过程中，第三子前框13的一端需要与第一子前框11的相抵接，为了实现相抵接，第三子前框13需要向靠近第一子前框11的方向相对背板2运动，而第二导向槽段522的第一端与第二限位槽段521靠近第一子前框11的一端相连接正是为了能够使第三子前框13能够沿第二限位槽段521向靠近第一子前框11的方向运动。
例如，在第二限位槽52开设于背板2后侧表面上，第二限位凸起51设置在第三子前框13的后壁上的实施例中，为了方便在背板2的边缘卡入第三子前框13的凹槽10的过程中实现第二限位凸起51与第二限位槽52卡接，第二限位槽52包括第二限位槽段521和第二导向槽段522，第二限位槽段521沿第一方向延伸，第二导向槽段522的第一端与第二限位槽段521远离或者靠近第一子前框11的一端相连接，第二导向槽段522的第二端延伸至背板2的后侧表面的边沿。在该实施例中，设置第二限位槽段521和第二导向槽段522所取得的有益效果与第二限位槽52开设于第三子前框13的后壁上的实施例中相同，在此不再赘述。
本公开实施例提供的显示设备中，第二子前框12与背板2的固定方式并不唯一，比如第二子前框12可以为以下固定方式：如图9所示，第二子前框12包括安装板121，安装板121与背板2的垂直于第一方向的表面(例如图9中的m面)固定连接。例如，安装板121通过螺纹紧固件(例如常见的螺钉)与背板2的垂直于第一方向的表面(例如图9中的m面)固定连接。另外，第二子前框12也可以为以下固定方式：第二子前框12具有一凹槽10，背板2的边缘卡入第二子前框12的凹槽10中，第二子前框12的后壁通过螺纹紧固件与背板2固定连接。相比第二子前框12的后壁通过螺纹紧固件与 背板2固定连接的固定方式，图9中所示的固定方式，安装板121是通过螺纹紧固件与背板2垂直于第一方向的表面(也就是背板2的侧面)固定连接，操作者直接可以通过螺纹紧固件将第二子前框12与背板2连接，而无需对显示设备进行180度翻转，这样就可以避免背板2内部的光学组件在翻转过程中发生错位，从而可以保证显示设备的装配质量，进而有利于提高显示设备的品质。
需要说明的是：在显示设备的装配过程中，通常是将显示设备的显示屏朝上进行放置，如果前框1的后壁需要通过螺钉与背板2连接，由于前框1的后壁是位于下方，这样安装螺钉会很不方便，此时是通过将显示设备进行180度翻转，使前框1的后壁位于上方，然而显示设备翻转180度会带来部件错位的风险。
第二方面，本公开实施例提供了一种显示设备，该显示设备包括上述任一的前框组装结构。
例如，显示设备可以为液晶电视、计算机显示器、手机等具有前框与背板结构的设备。
由于本公开实施例提供的显示设备中所包括的前框组装结构与上述任一的前框组装结构相同，所以也解决了相同的技术问题，达到了同样的技术效果。
至于显示设备的其它结构，已为本领域技术人员所公知，在此不再赘述。
本公开实施例提供的显示设备的前框组装结构及显示设备中，第一子前框、两个第三子前框均是通过卡接或者抵接的方式实现与背板的相对固定，这样在装配时，第一子前框、两个第三子前框与背板的连接就无需使用螺钉，直接通过简单的卡接或抵接就可以完成装配，无需操作者逐个拧紧螺钉，这样可以节省大量的装配时间和人力，有利于提高装配效率，降低人力成本；另外，由于第一子前框、两个第三子前框与背板的连接没有采用螺钉，这样背板内部就无需设置螺纹柱，从而可以大大减小对背板内部空间的占用，可以方便背板内部部件的优化布置；同时，由于第一子前框、两个第三子前框与背板的连接没有采用螺钉，这样也增加了该显示设备外观上的美感。
还有以下几点需要说明：
(1)本公开实施例的附图只涉及到与本公开实施例涉及到的结构，其 他结构可参考通常设计。
(2)为了清晰起见，在用于描述本公开的实施例的附图中，层或区域的厚度被放大或缩小，即这些附图并非按照实际的比例绘制。可以理解，当诸如层、膜、区域或基板之类的元件被称作位于另一元件“上”或“下”时，该元件可以“直接”位于另一元件“上”或“下”或者可以存在中间元件。
(3)在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合以得到新的实施例。
以上，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，本公开的保护范围应以权利要求的保护范围为准。
