交互平板集成了投影机、电子白板、幕布、音响、电视机、视频会议终端的多种功能，广泛应用于教育教学、企业会议、商业展示等领域，可有效改善沟通环境、提升群体沟通效率。
交互平板在结构上一般包括显示模组以及围设在显示模组四周的边框，边框内部装设有触摸检测组件，触摸检测组件包括触摸电路板和设置于触摸电路板上的红外线发射/红外线接收件。交互平板的两相对的边框中的其中一个边框内的触摸电路板上设置红外线发射件，另一个边框内的触摸电路板上设置红外线接收件。红外线发射件和红外线接收件在交互平板上形成红外线探测网，能够将用户的触摸动作转化成触控的坐标位置而实现操作的响应。为了对红外发射件和红外接收件的光线进行过滤，交互平板还在边框上设置有滤光条，以去除其他杂光。
传统的交互平板中的边框大部分为铝合金，边框成本较贵，为了降低边框成本，会采用辊轧边框代替传统的铝合金型材边框，辊轧边框一般指的是采用铁料通过辊轧工艺成型的边框，在辊轧边框的侧面会形成一开口，交互平板在装配时，滤光条会通过该开口内置于辊轧边框内，触摸电路板则内置于滤光条的内部空间内，然后将显示模块中的玻璃搭设在滤光条上，再通过相应的玻璃压块进行抵压固定。
由于滤光条内部装设有触摸电路板，玻璃还直接搭设在滤光条上。发明人经过研究分析发现，当滤光条装配不稳定时，会影响触摸电路板上的检测模块对用户触摸动作检测精度，此外，当滤光条装配不稳定时，位于滤光条上的玻璃也会存在跳脱的风险。又由于辊轧边框的侧面一般都会形成有较大的开口，因辊轧边框这种特殊的结构特性，导致滤光条在装配时，就必然需要考虑滤光条装配不稳定引起的上述问题。
为了解决上述问题，一些交互平板在装配滤光条时，通常会在滤光条的表面涂上胶，滤光条通过胶固定在辊轧边框内部，然而在实际使用过程中，胶水会存在脱落或者粘接不稳定、不可靠的问题，同样会因为滤光条装配不稳固，影响触摸电路板上的检测模块对用户触摸动作检测精度，以及还会引起滤光条上的玻璃发生跳脱。如果为了加大对滤光条粘结的稳固性，就需要增加胶水的用量，此时又存在溢胶，污染玻璃等其他部件的风险，除此之外，采用胶水固定滤光条，当需要更换时，拆装不便，在拆卸时，容易破坏滤光条。
此外，除了采用胶水固定滤光条外，一些交互平板在装配滤光条时，会在边框顶部或者 是玻璃压块顶部设置抵压螺钉，螺钉从上穿过边框或者是玻璃压块伸入辊轧边框内部去抵压滤光条，然后侧边通过玻璃压块对滤光条进行限位，从而实现对滤光条进行装配，然而，这种装配方式虽然能够将滤光条固定在辊轧边框内部，但是抵压螺钉在装配时，如果抵压螺钉太长，会干涉滤光条，在装配时会把滤光条顶变形，甚至顶坏触摸电路板，因此这种装配难度较大，存在破坏滤光条和其内部触摸电路板的风险；如果抵压螺钉太短，则会无法抵压滤光条，此时滤光条仍然会松动，同样会因为滤光条装配不稳固，影响触摸电路板上的检测模块对用户触摸动作检测精度，以及还会引起滤光条上的玻璃发生跳脱。
基于此，请参照图1至图3，发明人经过一系列的研究后提出了一种交互平板10，该交互平板10通过将第一滤光条210内置于第一边框110内部形成的安装腔1102内，第一滤光条210设置有用于承载玻璃300的承载部212，玻璃300搭设于承载部212上，再通过玻璃压块400对玻璃300进行抵压，玻璃压块400在侧边对第一滤光条210进行抵压限位，以限制第一滤光条210从开口1104处脱离。其中，第一滤光条210通过第一边框110用于形成安装腔1102的侧壁夹持以容置于安装腔1102；或第一滤光条210通过第一边框110用于形成安装腔1102的侧壁及玻璃压块400配合夹持以容置于安装腔1102。如此，第一滤光条210通过在第一边框110用于形成安装腔1102的侧壁夹持作用下，或者是在第一边框110用于形成安装腔1102的侧壁及玻璃压块400配合夹持，可以相对稳固地容置于安装腔1102部，进而降低因第一滤光条210装配不稳定而影响触摸电路板对用户触摸动作检测精度的风险，此外，当第一滤光条210相对稳固地容置于安装腔1102内时，还可以降低第一滤光条210上的玻璃300发生跳脱的风险。
需要说明的是，本申请涉及的交互平板10可以是具备书写、批注、绘画、多媒体娱乐以及网络会议等功能的电子设备，交互平板10可以融入人机交互、平板显示、多媒体信息处理和网络传输等多项技术，可以应用于办公、教学、图文互动演示等场景。
下面结合实施例阐述交互平板10的结构。
图1为交互平板10的结构示意图，图2为交互平板10的分解示意图，图3为玻璃300搭设在承载部212的状态示意图，图4为交互平板10的剖面图，请参照图1至图4，交互平板10包括第一边框110、第一滤光条210、玻璃300及玻璃压块400，第一边框110可以为辊轧边框，例如可以为辊轧铁边框，第一边框110内部形成有安装腔1102，第一边框110靠近交互平板10的显示区域的一侧形成有与安装腔1102连通的开口1104；安装腔1102和开口1104的形成可以在铁质边框在辊轧成型过程中形成。显示区域可以理解为交互平板10用于容纳显示模块的区域或者理解为交互平板10边框围设后形成的区域，例如图3中的A区域。
第一滤光条210内置于安装腔1102，第一滤光条210靠近显示区域的一端形成有承载部212，承载部212设置于开口1104处并通过开口1104显露。第一滤光条210可以由透明的PC(聚碳酸，Polycarbonate)材质通过注塑成型而成，玻璃300搭设在承载部212上。玻璃压块400的一端连接于第一边框110，另一端抵压于玻璃300背离承载部212的一侧，玻璃压块400的侧面与第一滤光条210位于开口1104处的部分抵接限位以限制第一滤光条210沿开口1104脱离安装腔1102。
请参照图3，承载部212为承载平面，玻璃压块400为塑胶，通过注塑成型而成，在安装时，虽然玻璃压块400直接与承载部212进行接触，且玻璃压块400也不会划伤玻璃300，因此，玻璃压块400和玻璃300之间无需再贴附缓冲部件，例如缓冲泡棉。
请参照图3和图4，第一滤光条210通过第一边框110用于形成安装腔1102的侧壁夹持以容置于安装腔1102；或者是第一滤光条210通过第一边框110用于形成安装腔1102的侧壁及玻璃压块400配合夹持以容置于安装腔1102。
可以理解的是，前述其中一种实施例中，第一滤光条210通过在第一边框110用于形成安装腔1102的侧壁夹持以容置于安装腔1102可以理解为：第一边框110用于形成安装腔1102的侧壁本身形成夹持架构，玻璃压块400仅在侧边对第一滤光条210进行抵接限位，如此，实现将第一滤光条210容置于安装腔1102。
前述另一种实施例中，第一滤光条210通过第一边框110用于形成安装腔1102的侧壁及玻璃压块400配合夹持以容置于安装腔1102可以理解为：在玻璃压块400的侧面抵持第一滤光条210的作用下，配合第一边框110本身形成的夹持架构共同夹持第一滤光条210使其容置于安装腔1102。或者是，第一边框110用于形成安装腔1102的侧壁和玻璃压块400共同配合形成夹持结构，通过该夹持结构对第一滤光条210进行夹持，使其容置于安装腔1102。
图5为一实施例中第一边框110的截面示意图，图6为另一实施例中第一边框110的截面示意图，请参照图3、图5和图6，在一些实施例中，第一边框110包括正面板体112、中间连接板体114以及背面板体116，正面板体112通过中间连接板体114与背面板体116连接并围设形成安装腔1102，正面板体112和背面板体116相对间隔设置并形成开口1104，其中，正面板体112和中间连接板体114之间形成的角度为a，其中，80°≤a≤90°。在一实施例中，a可以为：80°、81°、82°、85°、87°、88°、89°或90°。
在一实施例中，正面板体112和中间连接板体114之间形成的角度小于90°，也即87°≤a＜90°，如此，中间连接板体114和正面板体112两者之间可以相对偏移一定的角度，例如，如图5和图6所示，正面板体112朝中间连接板体114偏移一定的角度，如此，正面板体112 和中间连接板体114两者之间可以形成一定的夹持结构或者是正面板体112、中间连接板体114和背面板体116三者之间可以形成一定的夹持结构，通过夹持结构对第一滤光条210进行夹持，提升对第一滤光条210夹持的稳固性。此外，当正面板体112和中间连接板体114之间形成的角度小于90°时，此时背面板体116也更加靠近正面板体112，玻璃压块400在装配时，则可以更加稳固地抵压于玻璃300上，降低玻璃300发生跳脱的风险。
此外，当87°≤a＜90°，还不会因为正面板体112和中间连接板体114之间形成的角度过小影响对第一滤光条210的装配。
请继续参照图5和图6，背面板体116靠近显示区域的一端朝靠近正面板体112的方向弯折形成台阶部1162，请参照图5，在该实施例中，背面板体116整体形成类似“Z”字形结构，图6中的第一边框110与图5中的第一边框110相比，整体做窄边框设计，背面板体116和中间连接板体114的连接处整体收窄。
台阶部1162的设置为玻璃压块400的安装提供一个安装平台，玻璃压块400的一端连接于台阶部1162上。请继续参照图5和图6，其中一个实施例中，台阶部1162包括面向第一滤光条210的台阶平面部11622以及与台阶平面部11622连接并呈夹角设置的台阶竖向部11624，玻璃压块400连接于台阶平面部11622，台阶平面部11622与台阶竖向部11624之间垂直设置。
图6展示的第一边框110为窄边框设计，图6中台阶竖向部11624和中间连接板体114之间的间距比图5中台阶竖向部11624和中间连接板体114之间的间距小。图5和图6呈现的两个实施例中，第一边框110整体均设置有台阶部1162，如此便于承载玻璃300。
请参照图5和图6，当正面板体112和中间连接板体114之间形成的角度小于90°，也即，87°≤a＜90°时，台阶平面部11622整体会朝正面板体112的方向偏移，如此，玻璃压块400在装配时，由于台阶平面部11622更加靠近正面板体112，此时玻璃压块400则就可以整体往抵压于玻璃300的方向偏移或者是具备往抵压于玻璃300的方向偏移的趋势，进而玻璃压块400可以更加稳固地抵压于玻璃300上，降低玻璃300发生跳脱的风险。
图7为一实施例中第一边框110的截面示意图，图8为另一实施例中第一边框110的截面示意图，请参照图7和图8，在别的一些实施例中，台阶平面部11622相对台阶竖向部11624沿靠近第一滤光条210的方向偏移并与台阶竖向部11624之间形成的角度为b，其中，90°＜b≤100°。如此，台阶平面部11622会对第一滤光条210进行抵压，提升对第一滤光条210夹持的稳固性。此外，玻璃压块400在装配时，由于台阶平面部11622更加靠近正面板体112，此时玻璃压块400则就可以整体往抵压于玻璃300的方向偏移或者是具备往抵压于玻璃300的方向偏移的趋势，进而玻璃压块400可以更加稳固地抵压于玻璃300上，降低玻璃300发 生跳脱的风险。在一实施例中，b可以为91°、92°、93°、94°、95°、96°或100°。
在一实施例中，90°＜b≤93°，在该范围内，台阶平面部11622施加于第一滤光条210抵压更大，且又不会影响第一滤光条210的装配，提升对第一滤光条210夹持的稳固性。此外，玻璃压块400在装配时，由于台阶平面部11622更加靠近正面板体112，此时玻璃压块400则就可以整体往抵压于玻璃300的方向偏移或者是具备往抵压于玻璃300的方向偏移的趋势，进而玻璃压块400可以更加稳固地抵压于玻璃300上，降低玻璃300发生跳脱的风险。
在一实施例中，当正面板体112和中间连接板体114之间形成的角度小于90°，也即87°≤a＜90°，此时，台阶平面部11622整体靠近正面板体112的方向偏移的角度会相对变大，如此，玻璃压块400在装配时，台阶平面部11622更加靠近正面板体112，此时玻璃压块400则就可以整体往抵压于玻璃300的方向进一步偏移或者是往抵压于玻璃300的方向偏移的趋势更加明显，进而玻璃压块400可以进一步稳固地抵压于玻璃300上，进一步降低玻璃300发生跳脱的风险。
可见，在上述交互平板10中，第一滤光条210通过开口1104内置于安装腔1102，玻璃压块400设置在承载部212上，在通过玻璃压块400对玻璃300进行抵压，使得玻璃300固定于滤光条上。由于玻璃压块400的侧面与第一滤光条210位于开口1104处的部分抵接，进而可以限制第一滤光条210沿开口1104脱离第一滤光条210。在一实施例中，为了提升对第一滤光条210夹持的稳固性，第一边框110用于形成安装腔1102的侧壁本身形成夹持结构用于夹持第一滤光条210，使得第一滤光条210容置于安装腔1102；或者是，在玻璃压块400和第一边框110用于形成安装腔1102的侧壁配合形成夹持结构来夹持第一滤光条210，进而提升第一滤光条210在安装腔1102内安装的稳固性，进而降低因第一滤光条210装配不稳定而影响触摸电路板对用户触摸动作检测精度的风险，此外，当滤光条相对稳固地容置于安装腔1102内时，还可以降低第一滤光条210上的玻璃300发生跳脱的风险。
图9为玻璃压块400其中一个视角的结构示意图，图10为玻璃压块400的另一个视角的结构示意图，图11为第一边框110和第一滤光条210装配图，图12为图11中M处的放大示意图，图24为图11中R处的放大示意图，请参照图9至图12及图24，玻璃压块400和台阶平面部11622的其中一者设有第一定位凸起410，另一者设有第一定位孔11626，玻璃压块400通过第一定位凸起410和第一定位孔11626插接以与台阶平面部11622定位配合。如此，通过第一定位凸起410和第一定位孔11626的定位配合，可以将玻璃压块400定位安装于第一边框110上。请参照图10和图24，第一边框110位于台阶平面部11622处设有第一定位孔11626，玻璃压块400设有与第一定位孔11626定位配合的第一定位凸起410，第一定位凸起410可以为定位柱结构。
在一些实施例中，玻璃压块400和台阶平面部11622还通过紧固件固定配合。玻璃压块400可以直接通过紧固件固定于台阶平面部11622上或者是在玻璃压块400定位装设于台阶平面部11622后，再通过紧固件将玻璃压块400固定于台阶平面部11622上。在一实施例中，紧固件可以为螺钉。请参照图12和图24，台阶平面部11622和玻璃压块400均设有螺钉装配孔4000，玻璃压块400通过螺钉和螺钉装配孔4000固定于台阶平面部11622上。
图13为一实施例中第一滤光条210的结构示意图，图14为图13中S的放大示意图。请参照图13和图14，在一些实施例中，交互平板10还包括泡棉500，泡棉500连接于第一滤光条210的外侧壁，第一滤光条210通过泡棉500与第一边框110位于安装腔1102的内侧壁挤压配合以内置于安装腔1102内。在第一滤光条210和第一边框110之间设置泡棉500可以起到提升对第一滤光条210的夹持作用，使得第一滤光条210更加稳固的设置与安装腔1102内。
此外，第一滤光条210在装配至安装腔1102时，需要对第一滤光条210进行预定位或者是第一边框110及第一滤光条210组成的组件结构在转运时，为了避免第一滤光条210从安装腔1102处脱落，需要对第一滤光条210进行预固定，此时，在第一滤光条210和第一边框110之间设置泡棉500，在泡棉500的作用下，第一滤光条210可以预容置于安装腔1102，而不容易从安装腔1102脱落。
请参照图14，泡棉500的数量为至少两个，所有泡棉500沿第一滤光条210的长度方向间隔设置。第一滤光条210的长度方向为在图14中的C方向。
交互平板10一般呈方形结构，也即交互平板10一般具备四个边框，四个边框首尾相连，中间设置显示模块。四个边框的结构和材质则根据需要进行设置。
例如，图15为三个第一边框110装配后的结构示意图，图16为交互平板10的边框结构示意图；请参照图2、图15和图16，在一些实施例中，第一边框110的数量和第一滤光条210均为三个，三个第一边框110分别为上边框110a和两个侧边框110b，上边框110a指的是交互平板10在使用状态下，例如图15中的视角下，位于上方的边框，侧边框110b可以理解为左右两边的边框。三个第一滤光条210分别为两个侧边滤光条210b和上滤光条210a，侧边滤光条210b对应容置于侧边框110b的安装腔1102，上滤光条210a对应容置于上边框110a的安装腔1102。
上边框110a的两端可以分别与两个侧边框110b通过焊接的方式进行连接形成U型边框结构，采用焊接的方式进行连接，可以有效的管控上边框110a和侧边框110b在安装时产生的偏差或者是段差。当然了，在别的一些实施例中，上边框110a的两端还可以分别通过中间连接件与两个侧边框110b连接形成U型边框结构，中间连接件可以为转角件，通过转角 件连接上边框110a和侧边框110b。
图18为连接转角900的结构示意图，请参照图2、图16至图18，交互平板10还包括第二边框120及两个连接转角900，第二边框120为底边框120a，底边框120a指的是交互平板10在使用状态下，例如图16中的视角下，位于下方的边框。
在一些实施例中，第二边框120可以为铝合金边框。其中，底边框120a的两端和两个侧边框110b均对应设置一个连接转角900，且底边框120a通过对应的连接转角900与侧边框110b远离上边框110a的一端连接。连接转角900可以为塑胶结构，通过注塑成型的方式加工形成。
图19为第一边框110和第一滤光条210装配后的剖视图，请参照图19，第一滤光条210内部均设有容置腔218，交互平板10还包括三个第一触摸电路板700，分别为上电路板700a及两个侧边电路板700b，侧边电路板700b对应容置于侧边滤光条210b的容置腔218，上电路板700a对应容置于上滤光条210a的容置腔218。
在一实施例中，请参照图4和图19，第一滤光条210形成容置腔218的侧壁还开设有卡槽结构，第一触摸电路板700可移动地卡设于卡槽结构内。
图20为图15中N的放大示意图，图21为限位支架600在正面视角下的结构实体图，图22为限位支架600在背面视角的示意图，请参照图20-图22，上边框110a和侧边框110b的连接转角900处均设置有限位支架600，也即上边框110a与左侧边框110b和右侧边框110b处均设置有一个限位支架600。限位支架600均包括相互连接的限位体610以及第一锁定体620，限位体610设置于上边框110a和侧边框110b之间，第一锁定体620连接于上边框110a。
请参照图20至图22，限位体610包括朝向上边框110a的第一限位面612以及朝向侧边框110b的第二限位面614，在上边框110a的长度方向上，也即图20中的E方向，第一限位面612与上滤光条210a的端部及与上电路板700a的端部均限位配合，如此，在第一限位面612的限位作用下，上滤光条210a和上电路板700a均不会发生晃动或者因为装配误差原因晃动幅度在可接受范围内，进而可以降低因上滤光条210a装配不稳定而影响上电路板700a对用户触摸动作检测精度的风险，同时，在第一限位面612的作用下，上电路板700a本身也可以更加稳固的装设于容置腔218内，进一步降低上电路板700a在使用过程中因上电路板700a晃动而影响对用户触摸动作检测精度的风险，此外，通过第一限位面612对上滤光条210a进行限位，避免上滤光条210a在上边框110a的长度方向上晃动，还可以降低设置于上滤光条210a上的玻璃300发生跳脱的风险。
需要说明的是，第一限位面612与上滤光条210a的端部及与上电路板700a的端部限位配合，可以理解为第一限位面612与上滤光条210a的端部及与上电路板700a的端部是完全 抵靠接触或者因为装配误差原因，存在一定的间隙偏差。
同时，请继续参照图20和图21，在侧边框110b的长度方向上，也即图20中的D方向上，第二限位面614与侧边电路板700b的端部限位配合。如此，在第二限位面614的限位作用下，可以降低触摸电路板在使用过程中因触摸板晃动对用户触摸动作检测精度的风险。
需要说明的是，第二限位面614与侧边电路板700b的端部限位配合可以是两者完全抵靠接触或者因为装配误差原因，存在一定的间隙偏差。
从前述实施例可知，上滤光条210a和上电路板700a可以通过第一限位面612限位，侧边电路板700b则在第二限位面614作用下进行限位，但是还是无法降低侧边滤光条210b晃动对侧边电路板700b的影响。
为了解决前述问题，请参照图23，图23为一实施例中交互平板10的局部放大示意图，在一些实施例中，上滤光条210a和侧边滤光条210b相互接触抵靠，且在侧边框110b的长度方向，上滤光条210a的正投影至少部分落在侧边滤光条210b上，上滤光条210a的正投影也即是：上滤光条210a沿D方向上的投影，此时，上滤光条210a和侧边滤光条210b在侧边框110b的长度方向上存在重叠部分，进而，在侧边框110b的长度方向D上，上滤光条210a能够对侧边滤光条210b限位，如此，无需再额外设置相应的限位结构对侧边滤光条210b进行限位。在一实施例中，上滤光条210a和侧边滤光条210b相互抵靠除了可以实现相互限位外，还能起到避免漏光的作用。
需要说明的是，上滤光条210a和侧边滤光条210b相互接触抵靠可以是完全抵靠接触或者因为装配误差原因，存在一定的间隙偏差。
图17为侧边框110b和底边框120a通过连接转角900装配的示意图，请参照图17，在底部一侧，连接转角900朝向侧边滤光条210b的一侧还形成有第三限位面926，在侧边框110b的长度方向上，也即图23中的D方向上，第三限位面926与侧边滤光条210b的端部限位配合，第四限位面928与侧边电路板700b的端部限位配合。如此，第三限位面926和上滤光条210a的共同限位作用下，可以限制侧边滤光条210b在D方向上移动，进而，可以降低因侧边滤光条210b装配不稳定而影响侧边电路板700b对用户触摸动作检测精度的风险，此外，通过限制侧边滤光条210b在D方向上晃动，还可以降低侧边滤光条210b上的玻璃300发生跳脱的风险。在一实施例中，在第二限位面614和第四限位面928的共同限位作用下，可以限制侧边电路板700b在D方向移动，如此，侧边电路板700b本身也可以更加稳固的装设于容置腔218内，从而进一步降低侧边电路板700b在使用过程中因侧边电路板700b晃动而影响用户对触摸动作检测精度的风险。
需要说明的是，第三限位面926与侧边滤光条210b之间限位配合，可以是两者完全抵 靠接触或者因为装配误差原因，存在一定的间隙偏差。同理，第四限位面928与侧边电路板700b支架限位可以是两者相互抵靠可以是完全抵靠接触或者因为装配误差原因，存在一定的间隙偏差。
在一实施例中，请参照图20和图21，限位体610因设置了第一限位面612，可以对上滤光条210a和上电路板700a进行限位，为了提升对上滤光条210a和上电路板700a限位的可靠性，将第一锁定体620连接于上边框110a，此时使得第一限位面612始终可以保持与上滤光条210a和上电路板700a处于限位状态。
在一实施例中，请参照图21和图22，在一些实施例中，第一锁定体620和上边框110a的其中一者设有第二定位凸起622，另一者设有第二定位孔11628，第一锁定体620和上边框110a通过第二定位凸起622和第二定位孔11628插接以定位配合。如此，通过将第一锁定体620和上边框110a进行定位，可以使得限位支架600在安装时，第一限位面612能够与上滤光条210a和上电路板700a进行限位配合。请参照图12、图22和图23，在该实施例中，第一锁定体620设有第二定位凸起622，上边框110a设有第二定位孔11628，第二定位凸起622可以为定位柱结构。
请参照图20至图22，在一些实施例中，第一锁定体620和上边框110a还还可以通过紧固件固定配合，如此，在这些实施例中，可以直接将第一锁定体620直接固定在上边框110a上，从而使得第一限位面612与上滤光条210a和上电路板700a始终能够进行限位配合。或者是，通过先将第一锁定体620和上边框110a进行定位配合后，将第一锁定体620和上边框110a进行锁定固定，可以提升第一限位面612与上滤光条210a和上电路板700a之间限位配合的可靠性，使得第一限位面612能够始终与上滤光条210a和上电路板700a进行限位配合。在一实施例中，紧固件可以为螺钉紧固件。
然而，发明人经过一系列研究发现，当第一锁定体620通过紧固件锁定于上边框110a时，限位支架600整体相对上边框110a会有一定的翘起，使得限位支架600和侧边框110b存在一定的装配段差，如此，不利于后续对其他组件进行装配。
基于此，请参照图20至图25，图25在一些实施例中，限位支架600还包括第二锁定体630，第二锁定体630连接于限位体610背离上边框110a的侧壁，第二锁定体630与侧边框110b连接。如此，在与第一锁定体620相对的方向上再额外设置第二锁定体630，同时将第二锁定体630与侧边框110b进行连接，进而，可以降低限位支架600和侧边框110b之间的装配段差。
请参照图21和图22，第一锁定体620和第二锁定体630均可以是连接板体，整体为塑胶结构。
在一实施例中，第二锁定体630和侧边框110b之间可以通过卡接的方式进行连接。例如，请参照图25，第二锁定体630设有卡凸，侧边框110b设有卡持边，通过卡凸卡持于卡持边实现第二锁定体630和侧边框110b两者之间卡接配合。
在一实施例中，在前述实施例的基础上，请参照图22，限位支架600用于朝向交互平板10的背板2000的一侧还设有支撑体640，支撑体640用于支撑交互平板10的背板2000，避免在按压背板2000时出现坍塌。
下面将结合附图阐述连接转接的可选结构。
请往回参照图17和图18，连接转角900整体呈L型结构，连接转角900的其中一端用于与侧边框110b进行连接，另一端用于与底边框120a进行连接。连接转角900可以为塑胶结构，通过注塑成型而成。
在一实施例中，图26为图16中P的放大示意图，请参照图18和图26，在一些实施例中，连接转角900靠近侧边框110b的一端形成有夹持槽910，连接转角900通过夹持槽910夹持于侧边框110b朝向交互平板10的背板2000一侧，连接转角900相对的另一端插设于底边框120a的内部空腔内。夹持槽910夹持于侧边框110b上实质上起到对连接转角900进行定位的作用，在连接转角900通过夹持槽910夹持于侧边框110b时，连接转角900和侧边框110b再通过螺钉进行连接固定。夹持槽910的形成方式可以有很多种，例如，在连接转角900上挖设一凹槽形成夹持槽910，或者是在连接转角900上通过上下两个安装体间隔设置形成。在一实施例中，请参照图26，夹持槽910夹持于侧边框110b的台阶平面部11622上。
然而，侧边框110b装配过程中，例如是当侧边框110b为辊轧边框时，侧边框110b会相对底边框120a沿远离底边框120a的方向外翻，例如图26中的X方向，此时，侧边框110b和底边框120a在装配过程中形成的装配段差就相对较大。
基于此，请参照图18和图26，在一些实施例中，底边框120a朝向交互平板10的背板2000的一侧形成第一安装孔126和第二安装孔128，第一安装孔126和第二安装孔128沿底边框120a的宽度方向上间隔设置，底边框120a的宽度方向为图26中的Z方向，第一安装孔126相对第二安装孔128更靠近显示区域。连接转角900用于伸入底边框120a的内部空腔的部分形成有安装面920，安装面920设有第三安装孔922以及相对第三安装孔922沿远离安装面920方向突出的安装凸台924，安装凸台924对应第一安装孔126并配置为通过紧固件连接，换言之，紧固件穿过第一安装孔126与安装凸台924连接，第三安装孔922对应第二安装孔128并配置为通过紧固件连接，换言之，紧固件穿过第二安装孔128与第三安装孔922配合连接。
安装凸台924由于相对安装面920突出设置，在通过紧固件装配后，底边框120a位于安装凸台924的一侧会相对底边框120a位于第三安装孔922的一侧高，如此，如图26所示，底边框120a整体会有一个在Y方向的翻转，在底边框120a翻转时，会拉动侧边框110b沿靠近显示区域的一侧移动，如此，在底边框120a的拉动下，原本相对底边框120a沿X方向外翻的侧边框110b会被拉回，进而可以降低侧边框110b和底边框120a在装配过程中形成的装配段差。
在一实施例中，紧固件可以为螺钉，安装凸台924设有螺纹孔，螺钉穿过底边框120a上的第一安装孔126与该螺纹孔配合实现底边框120a和安装凸台924之间的连接。第一安装孔126和第二安装孔128可以为安装通孔，第三安装孔922可以为螺纹孔。
连接转角900一般都为塑胶件，通过连接转角900连接侧边框110b和底边框120a时，交互平板10在转角处强度会相对较低，为了确保交互平板10在转角处的强度要求，降低交互平板10在转角处被损坏的风险，则需要加强交互平板10在转角处的强度的整体强度。
图27为侧边框110b和底边框120a装配示意图，请参照图27，在一些实施例中，侧边框110b靠近底边框120a的一端弯折形成折弯部118，折弯部118与底边框120a拼接，折弯部118朝向底边框120a的一侧设有加强体1182，加强体1182伸入底边框120a的内部空腔内并与底边框120a连接，通过设置加强体1182与底边框120a连接可以加强交互平板10在此处的强度。在一实施例中，加强体1182与底边框120a可以通过螺钉进行连接。加强体1182和底边框120a通过螺钉连接还可以为解决EMC接地导通的问题。
需要说明的是，折弯部118与底边框120a拼接指的是折弯部118和底边框120a两者处于对接状态，折弯部118与底边框120a可以相会抵靠或者因为装配误差原因，两者存在一定的间隙偏差。
交互平板10除了包含上述边框和滤光条部件外，还包括一些音视频模块1000，例如摄像头和麦克风，音视频模块1000一般可以外置于边框外部，例如通过一些支架装设于边框的顶部，或者是在边框上开设安装槽，将音视频模块1000内置于安装槽内部。
请参照图1、图13至图14，图28至图30，图28为交互平板10的外围框架示意图，图29为图28中O的放大示意图，图30为图1中T的放大示意图。一些实施例中，第一边框110位于安装腔1102内设有用于容纳音视频模块1000的音视频区域1106，第一滤光条210对应音视频区域1106处形成有用于避让音视频模块1000的避让缺口216。由于第一滤光条210的材质一般为PC，当第一滤光条210开设了避让缺口216后，第一滤光条210在避让缺口216的周围的强度较低，在使用过程中，第一滤光条210在避让缺口216的底部处会朝向音视频模块1000的方向弯折，如此，会带动位于第一滤光条210内部的触摸电路板偏移， 从而影响第一触摸电路板700对于用户触摸动作的检测精度。
基于此，请参照图3和图12，在前述实施例的基础上，第一滤光条210朝向台阶部1162的一侧形成有限位凸起214；交互平板10还包括限位件3000，限位件3000穿设于台阶平面部11622中对应音视频区域1106的部分，且在第一边框110的高度方向上，如图3中的H方向，限位件3000相对限位凸起214更靠近避让缺口216，限位件3000朝向第一滤光条210的正投影至少部分落在限位凸起214，以使得限位件3000与限位凸起214在第一边框110的高度方向上限位配合。如此，在限位件3000的限位阻挡作用下，第一滤光条210在避让缺口216处不容易发生变形。限位件3000朝向第一滤光条210的正投影为：限位件3000在H方向的投影，此时，也可以理解为，在H方向上，限位件3000位于第一滤光条210的正上方。
在一实施例中，请参照图12和图14，限位凸起214沿第一边框110的长度方向延伸，限位凸起214与台阶部1162朝向第一滤光条210的侧面接触并密封配合，如此。限位凸起214的设置一方面可以起到限制第一滤光条210在避让缺口216处发生变形，另一方面还可以起到密封第一滤光条210和第一边框110之间的间隙，避免灰尘和水沿两者之间的间隙进入第一边框110的安装腔1102内，对安装腔1102内的部件造成一定的损失。
请参照图3，在该实施例中，限位件3000为螺钉，在一实施例中，第一边框110对应开设有螺纹孔，螺钉与螺纹孔螺纹配合，并延伸至与限位凸起214在第一边框110的高度方向上限位配合。当然，限位件3000还可以为其他柱形结构，通过柱形结构穿过第一边框110与限位凸起214限位配合。
在一实施例中，请参照图3和图28，音视频模块1000设置于上边框110a，上边框110a的安装腔1102内对应设置有音视频区域1106，上滤光条210a对应音视频区域1106对应设置有限位凸起214，螺钉穿过上边框110a与限位凸起214在H方向上限位配合。
请参照图2，交互平板10还包括第二滤光条220和第二触摸电路板800，第二触摸电路板800则位于底边框120a的内部空腔内，底边框120a朝向显示区域的一侧形成有卡接槽，第二滤光条220卡设于卡接槽内。
第二触摸电路板800和第一触摸电路板700的组成结构可以相同，可以为相关交互平板10中实现红外检测的触摸电路板。第二滤光条220也可以为透明PC材质，通过挤塑成型制成。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
