Description

液晶显示器的后盖、背光模组及液晶显示器
技术领域
本发明涉及到液晶显示领域，特别涉及到一种液晶显示器的后盖、背光模组及液晶显示器。
背景技术
液晶显示器是利用液晶来显示图像的平板显示装置，比其他显示装置具有轻薄、低驱动电压及低功耗等优点，已经在整个产业上得到广泛应用。然而，液晶显示面板不能自主发光，因此需要提供独立的人工光的背光源组合体给液晶显示器。
液晶显示器采用后盖来支撑整个背光模组，从而使背光模组的所有组件可以很好地固定，这就要求后盖具有高的强度和平整度，以保证背光模组中主要零件的平整度和配合度，另外，后盖还要兼具散热的功能，如果背光模组中背光源所产生的热量不能得到及时散发，则会降低背光源的发光效率。
目前后盖的主要做法是采用整块金属钣金，通过钣金冲压模具来成型后盖。但是，金属钣金材料的费用较高，而且钣金冲压模具很难成型，成型品质很难保证。
发明内容
本发明的主要目的为提供一种液晶显示器的后盖及通过该后盖来支撑的背光模组和设有该背光模组的液晶显示器，通过塑胶注射的方法制作后盖，使得后盖成型简单，且可降低材料成本。
本发明提供一种液晶显示器的后盖，用以支撑背光模组，所述后盖由后盖本体和嵌件组成，所述嵌件内嵌于所述后盖本体中，所述嵌件为金属钣金、陶瓷或热管嵌件，并呈中空的框架形状设置。
优选地，所述嵌件呈工字形或齿状设置。
优选地，所述嵌件由所述后盖本体包覆固定。
优选地，所述嵌件通过粘结或螺钉与所述后盖本体固定。
优选地，所述液晶显示器的后盖还包括一导热件，固定在所述后盖本体的一侧。
本发明还提供一种背光模组，通过后盖支撑该背光模组，所述后盖由后盖本体和嵌件组成，所述嵌件内嵌于所述后盖本体中，所述嵌件为金属钣金、陶瓷或热管嵌件，并呈中空的框架形状设置。
本发明还提供一种液晶显示器，包括背光模组和用以支撑背光模组的后盖，所述后盖由后盖本体和嵌件组成，所述嵌件内嵌于所述后盖本体中，所述嵌件为金属钣金、陶瓷或热管嵌件，并呈中空的框架形状设置。
本发明通过塑胶注射或模压成型的方式来形成后盖，提前将嵌件放在后盖本体的塑胶模具中，然后进行注射一次性成型，使后盖本体与嵌件牢固连接。后盖的成型简单，材料成本较低；其中，嵌件采用金属、陶瓷或热管等材料，不仅可以为后盖提供良好的强度和平整度，同时还具有优良的导热功能，可将背光模组所产生的热量及时散发出去。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
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。
图1为本发明液晶显示器的后盖第一实施例结构示意图。本实施例中液晶显示器的后盖用以支撑背光模组，该后盖由后盖本体10和嵌件20制成，嵌件20内嵌于后盖本体10中。
液晶显示器的后盖采用塑胶注射或模压成型的方式，将嵌件20提前放在后盖本体10的塑胶模具中，通过向模具中注射塑胶，便可形成后盖本体10与嵌件20的组合体，嵌件20内嵌在后盖本体10中，采用金属钣金材料、陶瓷或热管等导热性能优良且具有一定机械强度的材料，这样，嵌件20便可以为液晶显示器的后盖提供良好的强度和平整度，从而保证背光模组中组件的平整度。同时，由于该嵌件20采用导热性良好的材料，背光模组中背光源所产生的热量可通过其将热量散发出去。
为了使背光模组中的所有组件可以很好地被固定，保证背光模组中组件的平整度，嵌件20可采用中空框架形状，如图1所示，本实施例中将嵌件20的形状设计为工字型结构，采用这种结构的嵌件20，其平整度和稳定性都较高，可以很好地保证后盖强度和平整度。
图2为本发明液晶显示器的后盖第一实施例的局部截面示意图。如图所示，嵌件20由后盖本体10包覆固定。当嵌件20放在后盖本体10模具中后，向其中注射塑胶，在嵌件20的周边会形成后盖本体10，后盖本体10可将嵌件20与后盖本体10所连接的部分包覆住，以此来将嵌件20固定在后盖本体10 内。当然，嵌件20与后盖本体10的连接不限于包覆固定，也可通过粘结或螺钉与后盖本体10连接。
图3为图2中A部的放大图，示出了后盖本体与嵌件的一种连接形式。嵌件20与后盖本体10连接的部分设置为柱状，该柱状的顶端与后盖本体10相连接，并被后盖本体10包覆固定。
图4为本发明液晶显示器的后盖第一实施例的局部截面示意图，示出了后盖本体10与嵌件20的另一种连接形式。如图4所示，嵌件20与后盖本体10连接的部分也可设置为上、下两边分别有勾形突出的结构，并被后盖本体10包覆固定。
图5为本发明液晶显示器的后盖第一实施例的局部截面示意图，示出了后盖本体10与嵌件20的又一种连接形式。在嵌件20靠近两端位置的上、下两面分别设置有凹槽，嵌件20与后盖本体10相连接后，后盖本体10便将这一部分包覆固定。
采用图4和图5中所示结构的嵌件20，可使得后盖本体10对嵌件20包覆的面积更大，从而更为牢固地保证后盖本体10与嵌件20的固定连接。
参照图6，图6所示为本发明液晶显示器的后盖第一实施例的进一步改进。该液晶显示器的后盖还包括一导热件30，固定在后盖本体10的一侧。导热件30用于传导背光模组中背光源所产生的热量，更好地保证了液晶显示器的后盖的导热性能。
图7所示为本发明液晶显示器的后盖优选第二实施例，嵌件20的形状设计为齿状结构，后盖本体10也设计成与其相适配的齿状结构。这样，当采用整块金属钣金来制作后盖而使得材料的使用成本较高时，采用嵌件20与后盖本体10组合形成后盖的方式，可以很好地节约材料的成本，在此基础上，将嵌件20设计为中空的框架形状，可进一步降低材料使用成本。
本发明还提供一种背光模组，通过后盖来支撑整个背光模组，以保证背光模组中组件良好的平整度，采用塑胶注射或模压成型的方式，即将嵌件20提前放在塑胶模具中，通过向模具中注射塑胶来成型后盖，形成后盖后，嵌件20是内嵌在后盖本体10中的。同时，该嵌件20还具有良好的导热性，即可通过该嵌件20将背光模组中背光源所产生的热量散发出去。嵌件20为中空的框架形状。液晶显示器的后盖本体10用于支撑整个背光模组，从而使得背光模组中的所有组件可以很好地固定。
本发明还提出一种液晶显示器，包括背光模组和用以支撑背光模组的后盖，该后盖由后盖本体10和嵌件20制成，嵌件20内嵌于后盖本体10中。液晶显示器的后盖采用嵌件20与通过注塑而形成的后盖本体10组合的结构，可以保证背光模组中组件的平整度，同时可提供良好的导热性，将背光模组中背光源所产生的热量散发出去。
以上所述仅为本发明的优选实施例，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。
