显示器背框及液晶显示装置
【技术领域】
本发明涉及显示领域，特别是涉及一种显示器背框及液晶显示装置。
【背景技术】
现有的液晶显示器一般包括胶框、背框、液晶面板、光学膜片、导光板等。
其中，液晶显示器的胶框和背框的主要功能为固定光源、导光板以及光学膜片等光学零组件及承载液晶面板。
但是，目前液晶显示器的背框通常为一整体式的结构。一般使用金属冲压或者塑料注射方式整体成型，使得背框比较重，并且大尺寸背框需使用较大的冲压设备，对应的模具尺寸也很大，结构复杂，因此，增加了模具成本。进一步地，整体式的背框在运送以及仓储的过程中，所需占用的运输及仓储空间也较大，导致运输及仓储效率低。
再者，在固定光源、导光板以及光学膜片等光学零组件及承载液晶面板时，背框需要与胶框配合使用，一方面使得液晶显示装置的成本较高，另一方面增加了组装时间，降低了效率。
【发明内容】
本发明主要解决的技术问题是提供一种显示器背框及液晶显示装置，以能够降低背框在运输及仓储过程中的占用空间，提高运输及仓储效率，并且能够省去胶框，因此减低了成本。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种显示器背框，显示器背框由多个拼接件以拼接方式形成，其中至少部分拼接件之间通过转动机构连接，以使得显示器背框可在正常使用状态和折叠状态之间进行切换，其中显示器背框在折叠状态下的占用空间小于在正常使用状态下的占用空间，其中，拼接件包括主体部和挡墙，挡墙包括底部、侧壁和顶部，底部与主体部的外侧边缘水平连接，顶部与底部平行间隔设置，侧壁设置于底部与顶部之间，且主体部在与顶部相对的表面上设置有第一凸包，并且主体部在与顶部相对的表面上还设置有第二凸包，其中，第一凸包的高度大于第二凸包的高度；
其中，在正常使用状态下，多个拼接件包括：
平行间隔设置的第一支架和第二支架；
平行间隔设置的第三支架和第四支架，第三支架分别与第一支架和第二支架的一端垂直连接，第四支架分别与第一支架和第二支架的另一端垂直连接。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种显示器背框，显示器背框由多个拼接件以拼接方式形成，其中至少部分拼接件之间通过转动机构连接，以使得显示器背框可在正常使用状态和折叠状态之间进行切换，其中显示器背框在折叠状态下的占用空间小于在正常使用状态下的占用空间，其中，拼接件包括主体部和挡墙，挡墙包括底部、侧壁和顶部，底部与主体部的外侧边缘水平连接，顶部与底部平行间隔设置，侧壁设置于底部与顶部之间，且主体部在与顶部相对的表面上设置有第一凸包。
其中，主体部在与顶部相对的表面上还设置有第二凸包，其中，第一凸包的高度大于第二凸包的高度。
其中，在正常使用状态下，多个拼接件包括：
平行间隔设置的第一支架和第二支架；
平行间隔设置的第三支架和第四支架，第三支架分别与第一支架和第二支架的一端垂直连接，第四支架分别与第一支架和第二支架的另一端垂直连接；
其中，第一支架和第二支架之间还设置有多个辅助支架，辅助支架的两端分别与第一支架和第二支架连接。
其中，第一支架包括第一主体部和自第一主体部的一端垂直延伸的第一延伸部；第二支架包括第二主体部和自第二主体部的一端垂直延伸的第二延伸部；其中，第一延伸部与第三支架的一端、第三支架的另一端与第二主体部远离第二延伸部的一端、第二延伸部与第四支架的一端、第四支架的另一端与第一主体部远离第一延伸部的一端之间分别通过转动机构连接。
其中，在折叠状态，第一主体部和第四支架水平连接且位于第一延伸部和第二延伸部之间；第二主体部和第三支架水平连接且位于第一延伸部和第二延伸部之间，其中，第一主体部和第四支架水平连接时的总长等于第二主体部和第三支架水平连接时的总长。
为解决上述技术问题，本发明采用的又一个技术方案是：提供一种液晶显示装置，该液晶显示装置包括：
显示器背框，显示器背框由多个拼接件以拼接方式形成，其中至少部分拼接件之间通过转动机构连接，以使得显示器背框可在正常使用状态和折叠状态之间进行切换，其中显示器背框在折叠状态下的占用空间小于在正常使用状态下的占用空间，其中，拼接件包括主体部和挡墙，挡墙包括底部、侧壁和顶部，底部与主体部的外侧边缘水平连接，顶部与底部平行间隔设置，侧壁设置于底部与顶部之间，且主体部在与顶部相对的表面上设置有第一凸包；
导光板，设置于显示器背框内，其包括入光面与出光面；
光学膜片，设置于导光板上；
光源，设置在显示器背框朝向导光板的入光面的侧壁上；
液晶面板，设置于液晶显示器背框的顶部上；
前框，与显示器背框组装，以使液晶面板稳固夹持于前框与显示器背框之间。
本发明的有益效果是：区别于现有技术的情况，本发明的显示器背框一方面可在正常使用状态和折叠状态之间进行切换，并在折叠状态下的占用空间小于在正常使用状态下的占用空间；另一方面通过挡墙和第一凸包可以固定及支撑导光板、光学膜片以及液晶面板。因此，通过上述的设置，本发明能够降低背框在运输及仓储过程中的占用空间，提高运输及仓储效率，并可省去胶框，简化了组装过程，提高了组装效率，从而节约了成本。

【具体实施方式】
请一并参阅图1至图3，图1是本发明第一实施例的显示器背框在正常使用状态下的俯视图。图2是本发明主拼接件的结构示意图。图3是图2所示的主拼接件的立体结构示意图。如图1所示，显示器背框包括第一主拼接件110和130、第二主拼接件120和140、多个转动机构150以及多个止位机构160。
在本实施例中，第一主拼接件110和130以及第二主拼接件120和140包括主体部和挡墙，具体结构请参阅图2，如图2所示，主拼接件包括主体部101和挡墙102。其中，挡墙102包括底部103、侧壁104和顶部105。底部103与主体部101的外侧边缘水平连接，顶部105与底部103平行间隔设置，侧壁104设置于底部103与顶部105之间，因此，底部103、侧壁104和顶部105形成一U型结构，并且U型结构的开口向主体部101的方向。
请一并参阅图2和图3，本实施例中，主体部101在与挡墙102的顶部105相对的表面上设置有第一凸包106（如图2和图3所示），并且优选在主体部101的两端均设置有第一凸包106，有利于在组装导光板、光学膜片时，支撑导光板与光学膜片的四个角。进一步地，为了加强显示器背框的强度，主体部101在与挡墙102的顶部105相对的表面上进一步设置有第二凸包107（如图3所示），其中，第二凸包107与第一凸包106相连，并且第一凸包106的高度优选为大于第二凸包107的高度。
请再参阅图1，包括主体部和挡墙的第一主拼接件110和130以及第二主拼接件120和140以拼接方式形成显示器背框的外框架。其中，显示背框的外框架在正常使用状态形成一矩形结构。具体来说，第一主拼接件110和130之间平行设置，第二主拼接件120和140之间平行设置。第一主拼接件110和130的两端分别通过转动机构150与第二主拼接件120和140的一端连接，以使相邻的第一主拼接件110和130与第二主拼接件120和140可以转动机构150为轴进行相对转动，以使得显示器背框可在正常使用状态和折叠状态之间进行切换。
第一主拼接件110和130与第二主拼接件120和140的连接处设置有止位机构160，以在正常使用状态下固定第一主拼接件110和130与第二主拼接件120和140。在本实施例中，第一主拼接件110和130与第二主拼接件120、140的连接处均设置有止位机构160，以更好的对背框进行固定。在其他实施例中，为了节省成本以及降低复杂度，可仅在一个或几个连接处设置止位机构160来进行固定。在本实施例中，转动机构150和止位机构160可以由螺钉、铆钉、螺栓等任何适当的固定件实现。
参阅图4，图4是本发明第一实施例的显示器背框在折叠状态下的俯视图。相比与图1，在从正常使用状态切换到折叠状态时，可取下显示器背框的止位机构160，并使得第一主拼接件110和130与第二主拼接件120和140以转动机构150为轴进行转动，进而使得显示器背框的外框架从矩形结构变为平行四边形结构。因此，显示器背框在折叠状态下的占用空间小于在正常使用状态下的占用空间。
参阅图5与图6，图5是本发明第二实施例的显示器背框在正常使用状态下的俯视图，图6是本发明第二实施例的显示器背框在折叠状态下的俯视图。相比于第一实施例，在本实施例中的主拼接件依然采用平行设置的第一主拼接件110和130与第二主拼接件120和140。本实施例与第一实施例的不同之处在于，显示器背框进一步包括第一辅拼接件210和220与第二辅拼接件230。其中，第一辅拼接件210和220与第二主拼接件120和140平行，第二辅拼接件230与第一主拼接件110和130平行。
在本实施例中，第一辅拼接件210和220的两端通过转动机构150分别与两个第一主拼接件110和130连接，第二辅拼接件230的两端通过转动机构150分别与两个第一辅拼接件210和220连接。同样的，第一辅拼接件210和220与第一主拼接件110和130、与第二辅拼接件230的连接处均设置有止位机构160，以更好的对背框进行固定。在其他实施例中，可包括一个或多个第一辅拼接件，或多个第二辅拼接件，并且止位机构160可适当进行减少。
由于第一辅拼接件210和220与第二辅拼接件230设置于第一主拼接件110和130与第二主拼接件120和140所构成显示背框的外框架的内部，并平行于第一主拼接件110和130或第二主拼接件平行120和140，因此其同样可在图5所示的正常使用状态与图6所示的折叠状态之间进行切换，且在折叠状态下的占用空间小于在正常使用状态下的占用空间。
参阅图7与图8，图7是本发明第三实施例的显示器背框在正常使用状态下的俯视图，图8是本发明第三实施例的显示器背框在折叠状态下的俯视图。相比于第一实施例，在本实施例中的主拼接件依然采用平行设置的第一主拼接件110和130与第二主拼接件120和140。本实施例与第一实施例的不同之处在于，显示器背框进一步包括四个辅助机构170，第一主拼接件110和130的两端与第二主拼接件120和140的两端分别通过转动机构150与对应的辅助机构170连接。通过上述方式，本实施例的显示器背框同样可在图7所示的正常使用状态与图8所示的折叠状态之间进行切换，且在折叠状态下的占用空间小于在正常使用状态下的占用空间。
参阅图9，图9是本发明第四实施例的显示器背框在正常使用状态下的俯视图。在本实施例中，显示器背框包括两个第一主拼接件311和313、两个第二主拼接件312和314、四个辅助拼接件321、322、323和324、一个第一辅助机构331、四个第二辅助机构332、多个转动机构350以及多个止位机构360。
在正常使用状态，第一主拼接件311和313平行设置，第二主拼接件312和314平行设置，进而构成显示器背框的外框架。在本实施例中，第一主拼接件311和313与第二主拼接件312和314的一端通过转动机构350与对应的第二辅助机构332连接，另一端通过止位机构360与对应的第二辅助机构332连接。辅助拼接件321、322、323、324交叉设置，且一端通过转动机构350与对应的第二辅助机构332连接，另一端通过转动机构350与第一辅助机构331连接。
参阅图10，图10是本发明第四实施例的显示器背框在折叠状态下的俯视图。在从正常使用状态切换到折叠状态时，显示器背框中的止位机构360被取下，各辅助拼接件321、322、323和324以第一辅助机构331为中心进行转动，缩小显示器背框的宽度，以达到缩小显示器背框的占用空间的目的。同时，第一主拼接件311和313与第二主拼接件312和314以转动机构350为轴，使止位机构360固定的一端向第一辅助机构331处转动。与第一至第三实施例所不同的是，在本实施例中，以第一辅助机构331为中心转动辅助拼接件321、322、323和324，以此来实现在图9所示的正常使用状态与图10所示的折叠状态之间的切换，进而使得显示器背框在折叠状态下的占用空间小于在正常使用状态下的占用空间。
在其他实施例中，可对第四实施例进行简化，例如取消第二辅助机构332。第一主拼接件311和313的一端与第二主拼接件312和314的一端通过转动机构350与对应的辅拼接件321、322、323和324的一端连接。或者，辅拼接件321和323由一个辅拼接件代替，而辅拼接件323和324由另一个辅拼接件代替，并通过转动机构350在二者的中间位置进行连接。
请参阅图11，图11是本发明第五实施例的显示器背框在正常使用状态下的俯视图。在本实施例中，显示器背框包括第一支架510、第二支架520、第三支架530、第四支架540以及辅助支架550。
在正常使用状态，第一支架510和第二支架520平行设置，第三支架530和第四支架540平行设置，并以拼接方式形成显示器背框的矩形结构的外框架。辅助支架550设置在第一支架510和第二支架520之间，其两端分别与第一支架510和第二支架520连接，并且辅助支架550与第三支架530和第四支架540平行。其中，辅助支架550可以设置一个或多个。
请一并参阅图12，图12是第一支架510的立体结构示意图，本实施例中，第一支架510包括第一主体部511和自第一主体部511的一端垂直延伸的第一延伸部512，其中，第一主体部511的结构与图3所示的主拼接件的结构相同，在此不在赘述。
本实施例中，第二支架520的结构与第一支架510的结构相同，即第二支架520同样包括第二主体部521和自第二主体部521的一端垂直延伸的第二延伸部522。
请再参阅图11，第一延伸部512与第三支架530的一端、第三支架530的另一端与第二主体部521远离第二延伸部522的一端、第二延伸部522与第四支架540的一端、第四支架540的另一端与第一主体部511远离第一延伸部512的一端之间分别通过转动机构500连接。
相比于图11，图13是本发明第五实施例的显示器背框在折叠状态下的俯视图。在从正常使用状态切换到折叠状态时，可取下显示器背框的辅助支架550，并使得第一支架510和第二支架520与第三支架530和第四支架540以转动机构500为轴进行转动，进而使得显示器背框的外框架从矩形结构变为平行四边形结构。显示器背框在折叠状态时，第一主体部511和第四支架540水平连接且位于第一延伸部512和第二延伸部522之间，第二主体部521和第三支架530水平连接且位于第一延伸部512和第二延伸部522之间。进一步地，第一主体部511和第四支架540水平连接时的总长等于第二主体部521和第三支架530水平连接时的总长。
通过上述方式，本实施例的显示器背框同样可在图11所示的正常使用状态与图13所示的折叠状态之间进行切换，且在折叠状态下的占用空间小于在正常使用状态下的占用空间。
在其他实施例中，本领域技术人员完全可以在不付出创造性劳动的前提下对转动机构与止位机构的位置以及各种拼接件的设置进行互换或其他变化，只需使得至少部分拼接件之间通过转动机构连接，进而使得显示器背框可在正常使用状态和折叠状态之间进行切换即可实现本发明之目的，并不局限于图1-图13所示的实施例。
请参考图14，图14是本发明一种液晶显示装置的结构示意图，如图14所示，本发明的液晶显示装置600包括显示器背框610、导光板611、光学膜片612、光源613、液晶面板614以及前框615。
本实施例中，显示器背框610可为上述任一实施例中的显示器背框。导光板611包括入光面和出光面，其设置在显示器背框610内。光学膜片612设置于导光板611上。光源613设置在显示器背框610朝向导光板611的入光面的侧壁619上。液晶面板614设置于液晶显示器背框610的顶部620上，其中，液晶面板614与液晶显示器背框610的顶部620之间设置有一缓冲结构618，以减小显示器背框610与液晶面板614之间的摩擦，有效的保护了液晶面板614。
本实施例中，前框615与显示器背框610组装，具体为：前框615与显示器背框610的侧壁619通过多个卡扣616进行固定，以使液晶面板614稳固夹持于前框615与显示器背框610之间。
本实施例中，导光板611与光学膜片612进一步通过胶带和橡胶结构固定，具体如图15所示。
图15的导光板611中与入光面和出光面均垂直的两个侧面与其对应的光学膜片612的侧边通过胶带621固定，以组成光学组件，该光学组件的四个角通过四个橡胶结构622进一步固定，并且橡胶结构622固定在第一凸包617上（如图14所示）。
区别于现有技术的情况，本发明一方面通过挡墙和第一凸包可以固定及支撑导光板、光学膜片以及液晶面板，省去了胶框结构，提高了组装效率并降低了成本；另一方面使得显示器背框可在正常使用状态和折叠状态之间进行切换，并在折叠状态下的占用空间小于在正常使用状态下的占用空间，降低了背框在运输及仓储过程中的占用空间，提高运输及仓储效率。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
