具体实施方式
下面将结合本公开文本实施例中的附图，对本公开文本实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开文本一部分实施例，而不是全部的实施例。基于本公开文本中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开文本保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开文本所属领域内具有一般技能的人士所理解的通常意义。本公开文本专利申请说明书以及权利要求书中使用的“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。同样，“一个”或者“一”等类似词语也不表示数量限制，而是表示存在至少一个。“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相应地改变。
在一些实施例中，如图1和图2所示，提供一种导光板，包括导光板主体10，所述导光板主体10的侧面设有向外凸出的凸起部1，所述导光板主体10上还设有能够使得所述凸起部1弹性形变以定位固定所述导光板主体10的避位槽2。
导光板自身设置用于定位固定导光板的凸起部1和避位槽2，凸起部1与避位槽2相配合使得凸起部1弹性形变以实现导光板的定位固定，采用这样的方式固定导光板，导光板不会晃动，增强导光板固定的稳定性，对于改善产品摩擦性亮点有极大帮助，并且组装十分便捷，不需要单独设置其他卡接件等连接件，成本低。
为了防止避位槽2设置于导光板自身而影响导光板本身的导光效果，在所述一些实施例中，所述导光板主体10的侧面设有向外凸出的第一凸起20，所述凸起部1凸设于所述第一凸起20的侧面，所述避位槽2设置于所述第一凸起20上与所述凸起部1相对应的位置。
可选地，为了保证凸起部1的弹性形变量以利于导光板的定位固定，所述避位槽2的长度大于所述凸起部1的长度。
进一步地，为了使所述避位槽2能够容纳所述凸起部1的变形量，降低所述凸起部1受积压时的变型刚度，所述避位槽2的宽度大于所述凸起部1发生形变时的形变量。
所述一些实施例中，所述凸起部1的数量可根据实际需要设定，所述避位槽2的数量与所述凸起部1的数量相对应。根据需要容纳变形量的大小，对应一个所述凸起部1的所述避位槽2的数量也可为多个，这样设置的多个避位槽2相互平行，这样由多个避位槽2来容纳所述凸起部1的变型，接受变型的量更多。
所述一些实施例中，所述导光板主体10上至少相邻的两侧上设置所述凸起部1和所述避位槽2。

如图2所示，所述斜面与所述凸起部1的顶面之间的夹角为锐角，即所述斜面是向内倾斜形成的，由于定位固定导光板是通过凸起部1受力弹性形变实现的，斜面的设置用于在组装时，引导凸起部1向下移动，减小阻力利于导光板的定位固定。
在本公开文本一些实施例中，与参照图1和2描述的实施例的区别在于：所述导向结构由所述凸起部1的外侧面形成，所述外侧面包括从所述导光板主体10顶面向下延伸的第一连接面12和与所述第一连接面12相连的斜面13。如图3和图4所示。

所述凸起部1受力弹性形变以实现导光板的定位固定，采用这样的方式固定导光板，导光板不会晃动，增强了导光板固定的稳定性。
在所述一些实施例中，所述弧面为球面的一部分或者为圆柱面的一部分。
在本公开文本一些实施例中，与参照图1和2描述的实施例的区别在于：所述导向结构由所述凸起部1的外侧面形成，所述外侧面包括从所述导光板主体10顶面向下延伸的第二连接面15和与所述第二连接面15相连的弧面16。如图7和图8所示。
如图8所示，所述第二连接面15为平面结构，加强了导光板固定的稳定性，弧面16为向外凸出的曲面结构，弧面16通过其光滑的曲面结构减小了凸起部1的运动阻力，在使用时，弧面16的设置起到引导所述凸起部1沿着预定方向移动的导向作用，所述凸起部1受力弹性形变以实现导光板的定位固定，采用这样的方式固定导光板，导光板不会晃动，增强导光板固定的稳定性。此时，所述第二连接面15和固定导光板的连接部(此处的连接部可以设置于显示装置的背板或框体上)紧密连接，所述第二连接面15的长度可根据实际需要设定。
在本公开文本一些实施例中，与参照图1和2描述的实施例的区别在于：所述导向结构为设置在所述凸起部1外侧的第二凸起17，所述第二凸起17的外侧面与底面之间的过渡面为斜面或圆弧面。如图9和图10所示。
如图10所示，所述凸起部1的外侧面的下部向外凸起形成所述第二凸起17，所述第二凸起17的外侧面与底面之间的过渡面为圆弧面，所述第二凸起17的高度比所述凸起部1的高度低，第二凸起17相对于所述凸起部1更易形变，同时在所述过渡面的圆弧面的设置起到导向作用，更利于导光板的组装。
所述凸起部1受力弹性形变以实现导光板的定位固定，采用这样的方式 固定导光板，导光板不会晃动，增强导光板固定的稳定性。
