实施例一
本发明实施例提供的横竖两用的固定支架，如图1所示，包括背板101、定位件102和支撑轴103。背板101具有背板短边101a和背板长边101b，背板101中间设有与定位件102相配合的圆孔(例如盲孔)110，背板101的圆孔110的侧壁上设有凹槽101c；定位件102包括定位珠104和弹簧105，定位件102上设有开口102a。
定位件102用于连接支撑轴103和背板101，包括定位珠104和弹簧105，用于使支撑轴103固定、支撑背板101并实现横竖切换。该弹簧105例如为螺旋弹簧，该定位珠例如为钢珠。
定位件102靠近背板101的一端的侧面上设有开口102a，开口102a为孔洞形设计，在安装后，弹簧105设置于开口102a的孔洞内部，定位珠104由弹簧105顶出(即弹簧105处于压缩状态，对于定位珠104施加向外推的力)，例如开口102a的开口直径可以设置得小于定位珠104的直径，所以定位珠104不会从开口102a的孔洞内部完全弹出来(参见图6)。
背板101上设有凹槽101c。背板101中间对应圆孔的柱形孔洞内侧面具有凹槽101c。具体地，例如，定位珠104的尺寸可以与凹槽101c的尺寸相当，从而使得定位件102与背板101的紧固程度最大化。
例如，在定位件102靠近背板101的一端设置的定位珠104的数目可以为一个。并且，例如，凹槽101c的数目为四个，凹槽101c开口两两相对，凹槽101c开口朝向分别与背板101的边缘方向垂直。又例如，凹槽101c的数目为两个，这凹槽101c开口朝向分别与背板101的长边和短边方向垂直，这种情况仍然能够实现横竖切换。假设定位件102上的开口102a的初始朝向为垂直于背板101的长边101b，如图2所示，此时由于凹槽101c的存在，定位珠104在弹簧105的作用下为舒张状态，被弹出填充到凹槽101c中，起到定位的作用。当定位件102以垂直与背板101中间的圆孔的中心线为轴转动时，定位件102上的开口102a的朝向将发生变化。由于弹簧105的弹性，定位珠104将被背板101中间对应圆孔的柱形孔洞内侧面挤压，被压入定位件102的开口102a中。直到定位件102上的开口102a的朝向垂直于背板101的短边101a时，由于凹槽101c的存在，定位珠104在弹簧105的作用下重新为舒张状态，重新被弹出填充到凹槽101c中。此时定位件102与背板101相 对转动90°角，完成了图3中由(a)状态背板长边101b水平到(b)状态背板短边101a水平的状态变化，即使得背板由横屏显示转变为竖屏显示。
又例如，在另一个示例中，定位件102靠近背板101的一端的侧面上设有开口102a，开口102a为通孔设计，且包括两个定位珠。在安装后，弹簧105设置于开口102a的通孔内，两个定位珠分别位于弹簧两侧，定位珠104由弹簧105顶出，例如开口102a的开口直径可以设置得小于定位珠104的直径，所以定位珠104不会从开口102a的孔洞内部完全弹出来。并且，凹槽101c的数目为四个，凹槽101c开口两两相对，凹槽101c开口朝向分别与背板101的边缘方向垂直。在该情况下，两个定位珠可以同时卡入两个凹槽101c中。
又例如，在另一个示例中，如图10所示，在背板101的圆孔的侧壁上设置有孔洞，弹簧105设置于该孔洞内部，定位珠104由弹簧105顶出。例如该孔洞的开口的直径可以设置得小于定位珠104的直径，所以定位珠容纳在孔洞之中而不会从孔洞内部完全弹出来；相应地在定位件靠近背板101的一端的侧面上可以设置至少两个凹槽，该至少两个凹槽例如相对于定位件的中心轴线成90°角，当定位件安装在背板上的圆孔内时，定位珠可以由弹簧顶出而填充到定位件的侧面上的凹槽内，起到定位的作用。当定位件在背板的圆孔内转动时，可以能够实现横竖切换。
例如，支撑轴103的轴向与背板101平面可以成一定角度，该角度例如为30°～60°角，例如成45°角，如图3中(a)或(b)所示。
例如，定位件102远离背板101的一端可以设置有突起或凹槽，该突起或凹槽与支撑轴103上设置的凹槽或突起以插拔的方式相连。如图1所示，定位件102上的设置为凹槽，支撑轴103上的设置为突起。又例如，定位件102与支撑轴103之间的还可以采用螺纹连接等其他方式，本发明实施例不限于具体的连接方式。
例如，支撑轴103可以由弹性可变形橡胶材料制成，或者可以由塑料、木料、金属等制备。当支撑轴103由橡胶材料制成时，支撑轴由于具有类似于橡皮泥的性质，使得支撑轴可以任意改变形状，调节背板101的朝向，即背板101相对于观察者的观察角度，极大地方便了用户的观看体验。
实施例二
此外，本发明提供的另一实施例如图4、图5和图6所示。图4为该横竖两用的固定支架的侧视剖视图，加强的定位件102为图4中的阴影部分及嵌 装于开口102a中的定位珠104和弹簧105。
定位件102靠近背板101的一端、与背板101平行的切面为四分之三的第一切圆面102c，如图5横竖两用的固定支架的正视剖视图中阴影部分所示。特别地，图6为横竖两用的固定支架的局部放大的立体剖面图，当定位件102与背板101分离时，可更加清楚地看到立体的部分四分之三的第一切圆面102c。
背板101靠近定位件102的一端设有突起的立柱101d(如图4所示)，该突起的立柱101d与背板101平行的切面为四分之一的第二切圆面101e(如图5所示)。从图6中可更加清楚地看到立体的部分四分之一的第二切圆面101e。
具体的定位过程如下所述：
首先，定位件102的四分之三的第一切圆面102c与背板101的四分之一的第二切圆面101e的尺寸相匹配，使得定位件102得以伸进该中空的突起的立柱101d，成为初始位置，第一和第二切圆面的相对位置如图7中的(a)所示；
其次，与实施例一相似，当定位件102以垂直与背板101中间的圆孔的中心线为轴转动时，定位件102上的开口102a的朝向将发生变化，由于细颈102b的存在，使得定位件102的转动不受背板101上突起的立柱101d的限制。需要说明的是，细颈102b的长度h1与突起的立柱101d的高度h2相比较，h1略小于或等于h2，如图6所示；
然后，定位件102与背板101发生相对转动，直到定位件102上的开口102a的朝向垂直于背板101的短边101a时，由于凹槽101c的存在，定位珠104在弹簧105的作用下重新为舒张状态，被重新弹出填充到凹槽101c中，此时定位件102与背板101相对转动90°角，其相对位置如图7中的(b)所示，使得背板由横屏显示转变为竖屏显示。
实施例三
此外，如前所述的横竖两用的固定支架，其正面可以配合固定待固定物。如图8所示，背板101正面与长边101b和短边101a相对的位置均设有挂耳106，用以固定相应尺寸的电子产品，如电子相框、平板电脑、手机等等。当然，挂耳106也可以设置在背板101的长边101b和短边101a上；也可以只在长边101b或短边101a上设置，在此不一一列举。
实施例四
如前所述的横竖两用的固定支架，如图9所示，背板101设置有突起框107，用以在正面配合固定相应尺寸的电子产品。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
