触摸框组件以及智能交互平板 技术领域
本发明涉及触摸显示设备技术领域，具体而言，涉及一种触摸框组件以及智能交互平板。
背景技术
目前触摸框组件的红外感应高度(书写高度)普遍大于3.5mm，甚至有些产品红外书写高度大于4.5mm，用户在书写时，悬空感严重从而导致书写体验差，为了不断提高用户的书写体验，不断降低触摸书写高度，是必然的发展趋势，而红外书写高度其中有一大限制就是玻璃盖板内凹的管控。
特别是大尺寸的触摸平板，玻璃盖板的变形量更加难以管控，现有的玻璃盖板安装结构无法有效控制玻璃盖板的外凸，对于红外书写高度较低的显示设备，一旦出现玻璃盖板外凸，那么红外信号就会被遮挡，导致触摸识别失效。现有技术中，为了实现玻璃盖板内凹，只能通过挑选玻璃的方案实现，由此造成玻璃的损耗非常高，且生产效率低下，成本高昂。
发明内容
本发明提供一种触摸框组件以及智能交互平板，以解决现有技术中的通过挑选玻璃进行玻璃盖板内凹管控，导致玻璃的损耗大、成本高的问题。

根据本发明的另一方面，提供了一种智能交互平板，包括背光模组及上述提供的触摸框组件。
应用本发明的技术方案，该触摸框组件包括红外触摸框、玻璃盖板以及固定结构。在将玻璃盖板利用固定结构固定安装于框体之后，玻璃盖板会通过框体的曲度和/或固定结构控制玻璃盖板向内凹陷，进而避免玻璃盖板在使用过程中由于外凸而阻挡PCB组件的红外信号输送，能够保证红外触控操作正常进行。此外，采用上述结构的显示设备不需要通过挑选玻璃进行玻璃盖板内凹管控，能够减少玻璃的损耗，提高了生产效率，降低了生产成本。

具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1和图2所示，本发明实施例一提供一种触摸框组件，该触摸框组件包括红外触摸框10、玻璃盖板20以及固定结构，红外触摸框10包括框体11以及设置在框体11内的PCB组件12，玻璃盖板20位于PCB组件12的内侧，通过触摸玻璃盖板20可以进行触控操作。利用设置在框体11与玻璃盖板20之间的固定结构，能够将玻璃盖板20固定在框体11上，玻璃盖板20通过框体11的曲度和固定结构，可以控制玻璃盖板20向内凹陷。
应用本实施例提供的触摸框组件，在将玻璃盖板20利用固定结构固定安装于框体11上之后，通过框体11的曲度和固定结构可以控制玻璃盖板20向内凹陷，避免玻璃盖板20在使用过程中由于外凸而阻挡PCB组件12的红外信号输送，能够保证红外触控操作正常进行。此外，采用上述结构的显示设备，例如智能交互平板，不需要通过挑选玻璃进行玻璃盖板20内凹管控，能够减少玻璃的损耗，提高了生产效率，结构简单且成本低廉。
在本实施例中，框体作为该显示设备的边框，通过弯曲成型所得，其可以通过多种形式加工所得，例如滚压成型，使得框体11形成内凹面，并向内凹陷，且框体11的厚度保持一致。如图2所示，框体11的厚度保持一致。在本实施例中，背光模组位于显示设备的内部，PCB组件12安装于框体11内，玻璃盖板20位于PCB组件12的内侧。需要指出的是，框体11内设有PCB组件12，PCB组件12上设置红外发射管和红外接收管，红外发射管发射的红外线被红外接收管接收，在玻璃盖板的上方对应形成横竖交叉的红外线矩阵，当用户触摸屏幕时，控制器判断触点在屏幕上的具体位置，从而完成红外触控操作。
如图1和图2所示，玻璃盖板20位于PCB组件12的内侧，由于框体11向内弯曲，在将玻璃盖板20固定安装于框体11上之后，由于玻璃盖板20与弯曲的框体11相贴合，玻璃盖板20会向内凹陷。具体地，框体11形成了内凹的弧面，当玻璃盖板20与框体11固定连接时，玻璃盖板20随着框体11的凹陷发生变形，实现玻璃盖板20的内凹，再通过固定件60将玻璃盖板20固定在框体上，保持玻璃盖板20的内凹，从而避免玻璃盖板20在使用过程中由于外凸而阻挡PCB组件12发出的红外信号。如图1所示，图中箭头指向代表红外信号输送，此时玻璃盖板20内凹，信号正常输送，进而保证红外触控操作正常进行。
如图2所示，在本实施例中，框体11设置有用于连接玻璃盖板20的内凹面31，内凹面31朝背离PCB组件12的一侧凹陷，玻璃盖板20的部分表面贴设于内凹面31，固定结构将玻璃盖板20固定于红外触摸框上时，保持玻璃盖板20处于内凹状态。采用框体11整体的成型作业使得安装在其上的玻璃盖板20实现内凹，结构简单且成本低廉。
具体地，框体11背离PCB组件12的一侧弯曲形成凹陷，玻璃盖板20固定安装于框体11使得玻璃盖板20向内凹陷，即框体11形成了内凹的内凹面31，具体地，当玻璃盖板20固定连接在框体11内时，玻璃盖板20随着框体11的凹陷发生变形，实现玻璃盖板20的内凹，从而避免玻璃盖板20在使用过程中由于外凸而阻挡PCB组件12的红外信号输送，进而保证红外触控操作正常进行。
在本实施例中，内凹面31为弧形凹面。采用弧形凹面的结构，便于利用弧形凹面使玻璃盖板20发生形变。
在本实施例中，弧形凹面为对称结构，玻璃盖板20能够对称凹陷，使得玻璃盖板20的内凹更加稳定。优选的是，弧形凹面的最高点与玻璃盖板20的两端相对应设置，弧形凹面的最低点与玻璃盖板20的长边的中点相对应设置，弧形凹面的最高点与框体11的两端相对应设置，弧形凹面的最低点与框体11的长边的中点相对应设置，使得玻璃盖板20能够实现均匀凹陷，避免玻璃盖板20因局部凹陷变形过大造成玻璃盖板20破裂，此外，玻璃盖板20的长边长度大，则容易使得玻璃盖板20从中部向内侧发生弯折，从而实现玻璃盖板20内凹，为可选方案。
在本实施例中，弧形凹面的最高点与弧形凹面的最低点的高度差为H，H的取值范围为0.5mm-5mm。需要指出的是，当上述H值过小时，则使得玻璃盖板20的弯曲不够明显，此时 玻璃盖板20外凸时易导致红外信号无法正常输送，而当H值过大时则易导致玻璃盖板20发生断裂，故上述取值范围H值为可选方案。
在本实施例中，玻璃盖板20的外轮廓为矩形，玻璃盖板20的长边与内凹面31相连接，如此便于玻璃盖板20发生形变。
在本实施例中，框体11为滚压弯曲型材，即框体11被滚压形成内凹的弧面，加工方便且成本低廉。其中，框体11的厚度保持一致。
如图1、图6以及图7所示，框体11设置有用于支撑玻璃盖板20的第一台阶111，玻璃盖板20的部分表面与第一台阶111的台阶面相抵接，且玻璃盖板20的端部被第一台阶111所支撑，上述结构使得玻璃盖板20的安装更加方便且抵接更稳定。在将玻璃盖板20放入第一台阶111之后，利用固定结构对玻璃盖板20进行固定，能够避免玻璃盖板20发生滑脱，且第一台阶111具有一个定位作用，便于玻璃盖板20的安装。其中，图1中玻璃盖板20的端部与第一台阶111之间具有间隔，由于各部件在加工过程中存在加工误差，通过设置该间隔，能够保证玻璃盖板20顺利装入框体11内。
具体地，内凹面31设置于第一台阶111的台阶面上，在将玻璃盖板20放入第一台阶111之后，在利用第一台阶111进行定位的同时可实现玻璃盖板20的内凹。
如图1、图2、图8以及图9所示，在本实施例中，该显示设备还包括若干固定件60，各固定件60分别与框体11和玻璃盖板20的内表面相连接，由此固定件60将玻璃盖板20的内表面与边框进行固定，从而使得玻璃盖板20牢固地固定在框体11内。
具体地，固定件60的第一端通过螺钉与框体11连接，固定件60的第二端位于第一台阶111上方，且固定件60的第二端压设在玻璃盖板20上，以将玻璃盖板20牢固地固定在框体11内。
在本实施例中，固定件60为玻璃压块，各玻璃压块沿玻璃盖板20的长度方向呈均匀分布，从而使得玻璃盖板20稳定地固定在框体11上，需要指出的是，也可以在玻璃盖板20的短边上设置玻璃压块，只是玻璃盖板20的长边的长度较长，在长边上设置玻璃压块能够更好实现玻璃盖板20的稳定连接，在进行玻璃盖板20安装时，通过锁紧螺钉，锁紧玻璃压块，进而使得玻璃盖板20内凹并固定在框体11上。
在其它实施例中，可将玻璃盖板20与内凹面31粘接连接。即玻璃盖板20采用双面胶或液体胶粘接于框体11内，从而实现玻璃盖板20与框体11之间的固定连接。
在本实施例中，框体11包括第一安装槽112，PCB组件12设置于第一安装槽112内，由此便于安装且保护PCB组件12。
具体地，第一安装槽112的槽壁设有卡槽1121和第二台阶1122，PCB组件12的一端与卡槽1121相卡接，PCB组件12的另一端与第二台阶1122的台阶面相粘接，从而使得PCB 组件12稳定地设置在第一安装槽112内，避免PCB组件12发生晃动，保证触控操作正常运行。
此外，该触摸框组件还包括滤光条40，为了使得滤光条40稳定连接，滤光条40安装于第一安装槽112的槽口。
采用实施例一的触摸框组件，框体11背离PCB组件12的一侧弯曲形成凹陷，玻璃盖板20固定安装于框体11使得玻璃盖板20向内凹陷。具体地，当玻璃盖板20固定连接在框体11内时，由于框体11被显示设备的背光模组固定，则玻璃盖板20随着框体11的凹陷发生变形，实现玻璃盖板20的内凹，从而避免玻璃盖板20在使用过程中由于外凸而阻挡PCB组件12的红外信号输送，进而保证红外触控操作正常进行。此外，采用上述结构的显示设备不需要通过挑选玻璃进行玻璃盖板20内凹管控，减少玻璃的损耗，提高了生产效率，而采用框体11整体的成型作业使得安装在其上的玻璃盖板20实现内凹，结构简单且成本低廉。
如图3所示，本发明实施例二提供一种触摸框组件，实施例二与实施例一的区别在于，在实施例二中，框体11的中部的厚度大于框体11的两端的厚度，以形成内凹面31。
在本实施例中，框体11设置有用于连接玻璃盖板20的加工面，加工面为内凹面31，该加工面可以通过机加工得到，内凹面31可以为弧形凹面，也可以是断差面，能够使得加工面沿其两端向中部逐渐凹陷即可，玻璃盖板20的表面贴设于内凹面31，此时玻璃盖板20与内凹面31相紧贴，通过固定件将玻璃盖板20连接固定在框体11上，使得玻璃盖板20向内弯曲，从而使得玻璃盖板20向内凹陷，进而避免玻璃盖板20在使用过程中由于外凸而阻挡PCB组件12发出的红外信号。
本实施例中通过固定件将玻璃盖板20连接固定在框体11上与实施例一中的方案相同，在此不再赘述。
应用本实施例提供的触摸框组件，将玻璃盖板20贴设于内凹面31，使得玻璃盖板20向内凹陷，从而避免玻璃盖板20在使用过程中由于外凸而阻挡PCB组件12的红外信号输送，进而保证红外触控操作正常进行。此外，采用上述结构的显示设备只需在框体11上加工得到内凹面31，不需要通过挑选玻璃进行玻璃盖板20内凹管控，减少玻璃的损耗，提高了生产效率，而内凹面31的加工成本低且实现了玻璃盖板20的内凹，结构简单且成本低廉。
在本实施例中，框体11的中部的厚度大于框体11的两端的厚度，即通过切削框体11的两端形成内凹面31，从而使得框体的内凹面31加工更加方便。玻璃盖板20的外轮廓为矩形，玻璃盖板20的长边与内凹面31相连接，玻璃盖板20的长边长度大，当玻璃盖板20长边与内凹面31进行连接时，容易使得玻璃盖板20从中部向内凹陷。
具体地，内凹面31为弧形凹面，弧形凹面为对称结构，使得玻璃盖板20能够对称凹陷，使得玻璃盖板20产生均匀的内凹形变，弧形凹面的最高点与玻璃盖板20的两端相对应设置，即弧形凹面的最高点为框体11的两端点或在框体11的两端点附近，弧形凹面的最低点与玻璃盖板20的长边的中点相对应设置，即弧形凹面的最低点为框体11的中点或在框体11的中点 附近，进一步使得玻璃盖板20能够实现均匀凹陷，避免玻璃盖板20因局部凹陷变形过大造成玻璃盖板20破裂。
其中，弧形凹面的最高点与弧形凹面的最低点形成的高度差H，H的取值范围为0.5mm-5mm，需要指出的是，当上述H值过小时，则使得玻璃盖板20的弯曲不够明显，此时玻璃盖板20外凸时易导致红外信号无法正常输送，而当H值过大时则易导致玻璃盖板20发生断裂，故上述取值范围H值为可选方案。
采用实施例二的触摸框组件，框体11设置有用于连接玻璃盖板20的加工面，加工面为内凹面31，内凹面31向内凹陷，玻璃盖板20的背面贴设于内凹面31，通过固定件将玻璃盖板20与框体11固定连接，使得玻璃盖板20向内凹陷，从而避免玻璃盖板20在使用过程中由于外凸而阻挡PCB组件12的红外信号输送，进而保证红外触控操作正常进行。此外，采用上述结构的显示设备只需在框体11上加工得到内凹面31，不需要通过挑选玻璃进行玻璃盖板20内凹管控，减少玻璃的损耗，提高了生产效率，而内凹面31的加工成本低且实现了玻璃盖板20的内凹，结构简单且成本低廉。
如图4和图5所示，本发明实施例三提供一种触摸框组件，实施例三与实施例一的区别在于，在实施例三中，在玻璃盖板20和框体11之间设置支撑垫32，支撑垫32产生使玻璃盖板20向内凹陷的作用力，使得玻璃盖板20向内凹陷。
本实施例中玻璃盖板20的外表面朝向显示设备的外侧，需要指出的是，PCB组件12上设置有一一对应的红外发射管和红外接收管，使得屏幕上对应形成横竖交叉的红外线矩阵，当用户触摸屏幕时，控制器判断触点在屏幕上的具体位置，从而完成红外触控操作。
如图4和图5所示，PCB组件12安装于框体11内，玻璃盖板20位于PCB组件12的内侧，即红外发射管发射的红外线位于玻璃盖板20的外表面上方，玻璃盖板20的两端固定连接于框体11内。由于玻璃盖板20的两端与框体11固定连接，通过将支撑垫32设置在框体11和玻璃盖板20之间，玻璃盖板20在支撑垫32的支撑下会发生形变，从而使得玻璃盖板20向内凹陷。
在本实施例中，固定结构包括固定件60，固定件60的两端分别与框体11和玻璃盖板20的内表面相连接。具体地，玻璃盖板20的两端通过玻璃压块与框体11相固定，支撑垫32形成支点，利用支撑垫32挤压玻璃盖板20，使得玻璃盖板20向内凹陷，从而避免玻璃盖板20在使用过程中由于外凸而阻挡PCB组件12发出的红外信号，如图4所示，图中箭头指向代表红外信号输送，此时玻璃盖板20内凹，信号正常输送，进而保证红外触控操作正常进行。此外，采用上述结构的显示设备不需要通过挑选玻璃进行玻璃盖板20内凹管控，减少玻璃的损耗，提高了生产效率，而支撑垫32实现了玻璃盖板20的内凹，结构简单且成本低廉。
在本实施例中，玻璃盖板20的外轮廓为矩形，一个支撑垫32设置于玻璃盖板20的长边的中点处，玻璃盖板20的长边长度大，则容易使得玻璃盖板20从中部向内凹陷，且使得玻璃盖板20呈现对称弯折，不易导致玻璃盖板20破裂。需要指出的是，也可以在玻璃盖板20 的短边上设置支撑垫32，只是会导致玻璃盖板20弯曲效果不够好，也导致玻璃盖板20的内凹程度不够。
在其它实施例中，可以设置多个支撑垫32，将多个支撑垫32均匀间隔设置。
具体地，支撑垫32为块状，支撑垫32的长度与玻璃盖板20的长边的长度的比值为a，其中a的取值范围在1/8至1/12之间，支撑垫32的厚度与玻璃盖板20的厚度之间的比值为b，其中b的取值范围在1/3至1/4之间。需要指出的是，支撑垫32的长度太小则容易导致玻璃盖板20局部受到挤压而发生断裂，而支撑垫32的长度过大则在挤压玻璃盖板20时与玻璃盖板20的接触不够充分，则使得玻璃盖板20弯曲效果不明显；支撑垫32的厚度太小则使得玻璃盖板20弯曲内凹不明显，而当支撑垫32的厚度过大时则易导致玻璃盖板20发生断裂，故上述取值范围的a和b为可选方案。
在本实施例中，支撑垫32粘接于框体11，从而使得支撑垫32与框体11稳定连接。在其它实施例中，支撑垫32也可以采用紧固件等其他方式固定在框体11上，只是采用粘接的形式更加方便且牢固。
在本实施例中，支撑垫32的材料为塑胶或泡棉，由此在挤压玻璃盖板20时不易造成玻璃盖板20损坏，从而提高该结构的稳定性。
在进行玻璃盖板20安装时，首先将玻璃盖板20两端的玻璃压块压紧，此时玻璃盖板20中部的支撑垫32挤压使得玻璃盖板20发生弯曲，此后将位于玻璃盖板20中部的玻璃压块锁紧，进而使得玻璃盖板20内凹并固定在框体11上。
采用实施例三的触摸框组件，玻璃盖板20的两端与框体11相固定，利用支撑垫32挤压玻璃盖板20，使得玻璃盖板20向内凹陷，从而避免玻璃盖板20在使用过程中由于外凸而阻挡PCB组件12的红外信号输送，进而保证红外触控操作正常进行。此外，采用上述结构的显示设备不需要进行玻璃的挑选进行玻璃盖板20内凹管控，减少玻璃的损耗，提高了生产效率，而支撑垫32实现了玻璃盖板20的内凹，结构简单且成本低廉。
本发明实施例四提供了一种智能交互平板，包括背光模组及上述提供的触摸框组件，背光模组设置在触摸框组件的内侧。
