Description

一种电子设备触摸屏的安装结构及电子设备 技术领域
本实用新型实施例涉及但不限于触摸屏安装技术领域，尤其涉及一种电子设备触摸屏的安装结构及电子设备。
背景技术
随着人们生活水平的提高，移动终端手持电子设备的使用越来越广泛，例如手机、平板电脑等，越来越多的电子设备上设置有触摸屏，为了吸引消费者的眼球，一方面，触摸屏越做越大，且为了得到更好的视觉效果，触摸屏和显示屏往往采用两件贴合的方式，因此导致了触摸屏组件重量增加，跌落等测试时，触摸屏组件往往起翘。
另一方面，边框越做越窄，当触摸屏两侧的粘接面宽度达到1.0毫米以内时，普通胶带已经无法模切出来，厂家则逐渐采用胶水粘接方案，但是胶水粘接方案往往会发生溢胶问题，影响电子设备的外观效果，此外，采用胶水粘接的触摸屏，拆解难度高，也会在拆解时将胶水大量残留到触摸屏面上，造成胶水清理困难，甚至导致触摸屏报废。
实用新型内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本实用新型实施例提供了一种电子设备触摸屏的安装结构及电子设备，能够避免溢胶，提高粘接力，并降低维修时的拆解难度。
本实用新型实施例提供了一种电子设备触摸屏的安装结构，包括：
触摸屏本体；
电子设备壳体，所述电子设备壳体上设置有用于固定安装所述触摸屏本体的安装框架，且所述安装框架上设置有多个通孔；
其中，所述电子设备壳体的与所述触摸屏本体背离的一侧设置有与所述 通孔连通的沉槽，所述沉槽和所述通孔内填充有粘接剂，且所述沉槽和所述通孔内的粘接剂将所述安装框架与所述触摸屏本体粘接连接。
可选地，所述安装框架上还设有多个盲孔，所述盲孔内填充有粘接剂，且所述盲孔内的粘接剂将所述安装框架和所述触摸屏本体粘接连接。
可选地，所述沉槽内的粘接剂中还嵌入有一螺钉。
可选地，所述安装框架与所述触摸屏本体之间还粘贴有胶带，且所述沉槽和所述通孔内的粘接剂将所述胶带和所述安装框架粘接连接。
可选地，所述胶带上与所述通孔对应的位置处还开设有避让孔。
可选地，其中，所述避让孔的尺寸大于等于所述通孔的尺寸。
可选地，其中，所述电子设备壳体为通过等离子活化工艺处理后的电子设备壳体。
可选地，其中，所述粘接剂为聚氨酯热熔胶或紫外光固化胶。
本实用新型实施例还提供了一种电子设备，包括如上述所述的电子设备触摸屏的安装结构。
本实用新型实施例的电子设备触摸屏的安装结构，通过电子设备壳体上的安装框架与触摸屏本体固定连接，并在安装框架上开设多个通孔，以及用于避免溢胶且与通孔相通的沉槽，使得填充在通孔和沉槽内的粘接剂将安装框架和触摸屏本体粘接连接，有效避免了溢胶现象，并增加了触摸屏本体和电子设备壳体之间的粘接力。
此外，由于填充在通孔和沉槽内的粘接剂固化后，形成了铆接结构，因而，在维修时，对粘贴有触摸屏本体的电子设备壳体加热后，用吸盘等工具从触摸屏本体一侧拉开触摸屏本体后，铆钉结构的胶水也有利于将胶水留在电子设备壳体上而不是留在触摸屏本体上。
在阅读并理解了附图和详细描述后，可以明白其他方面。

本实用新型的实施方式
下面将结合附图对本实用新型实施例进行详细描述。
依据本实用新型实施例的一个方面，提供了一种电子设备触摸屏的安装结构，如图1所示，包括：
触摸屏本体1；
电子设备壳体2，所述电子设备壳体2上设置有用于固定安装所述触摸屏本体1的安装框架3，且所述安装框架3上设置有多个通孔4；
其中，所述电子设备壳体2的与所述触摸屏本体1背离的一侧设置有与所述通孔4连通的沉槽5，所述沉槽5和所述通孔4内填充有粘接剂6，且所述沉槽5和所述通孔4内的粘接剂6将所述安装框架3与所述触摸屏本体1粘接连接。
其中，触摸屏本体1的四周下方采用胶带8或粘接剂6(例如胶水)粘接到安装框架3上，即图1中的胶带8为可选，同时在粘接区域内，即安装框架3上设置通孔4，该通孔4从安装框架3的一侧贯穿至另一侧，通孔4的截面可以是圆形、矩形、菱形、椭圆形等，且根据粘接面的大小，孔径大小和孔的间距大小可根据实际需求进行设计。
此外，通孔4内的粘接剂6会在固化后会形成铆钉结构，为了能够形成更大的铆钉结构而增加粘接效果，或者避免在粘接剂6的填充过程中造成溢 胶，可在电子设备壳体2的与触摸屏本体1背离的一侧设置与通孔4连通的沉槽5。其中，沉槽5的截面形状可以是圆形、矩形、菱形、椭圆形等，且从沉槽5表面到通孔4处，可以为C角(如图2)或者直角(如图3)。
当触摸屏本体1与安装框架3之间通过胶水粘接时，胶水从电子设备壳体2粘接触摸屏本体1的一侧直接喷涂或点涂到安装框架3上，在粘接面上进行点胶时，部分胶水流入通孔4中。此外，在装配触摸屏本体1的过程中，胶水也会被挤压进通孔4内，形成与孔相对应的形状，即形成铆接结构，同时与通孔4的内壁粘接。
当触摸屏本体1与安装框架3之间通过胶带8粘接时，在触摸屏本体1与安装框架3利用胶带粘接完成后，从电子设备壳体2的背离粘接面的一侧，在通孔4内灌装胶水，使得胶带8与安装框架3通过胶水粘接连接。此外为了提高点胶效率，可将电子设备壳体2背面朝上放到夹具上进行定位，为了控制胶量的一致性，可使用喷胶机、点胶机等辅助设备进行点胶，使得触摸屏本体1的粘接效果更加美观。
其中，如图2所示，为了增加触摸屏本体1与安装框架3之间的粘接效果，可在触摸屏本体1与安装框架3之间的胶带8上，与所述通孔4对应的位置处开设避让孔9。其中，所述避让孔9的尺寸大于等于所述通孔4的尺寸。
此外，对于本实用新型实施例的电子设备触摸屏的安装结构，在维修时，可以对粘贴触摸屏本体1的电子设备壳体2加热，然后利用吸盘等工具从触摸屏本体1的一侧拉开触摸屏本体1，此时，铆钉结构的胶水则留在电子设备本体1上，而不会留在触摸屏本体1上。
因此，本实用新型实施例的电子设备触摸屏的安装结构，能够避免溢胶问题，提高了触摸屏本体1和电子设备壳体2的粘接力，并且降低了维修时的拆解难度和清理难度。
可选地，所述安装框架3上还设有多个盲孔，所述盲孔内填充有粘接剂6，且所述盲孔内的粘接剂6将所述安装框架3和所述触摸屏本体1粘接连接。其中，所述盲孔可在触摸屏本体1与安装框架3的粘接过程中，避免造成溢胶问题。当然，可以理解的是，在安装框架3上可单独设置盲孔，也可单独 设置通孔4，也可同时设置盲孔和通孔4。
可选地，如图4所示，为了增加粘接剂6与电子设备壳体2的粘接面积，加强铆接强度，可在沉槽5和通孔4内的粘接剂6填充完成后，在粘接剂6中埋入螺钉7，待粘接剂6固化后，螺钉7充分与粘接剂6结合，形成强度更好的铆接结构。
可选地，所述电子设备壳体2为通过等离子活化工艺处理后的电子设备壳体2，能够提高电子设备壳体2的粘胶面的表面活性，进而提高胶带8或粘接剂6与电子设备壳体2的粘接力。
可选地，所述粘接剂6为聚氨酯热熔胶或紫外光固化胶，此种粘接剂6流动性较好，更加便于在通孔4及沉槽5中进行填充。
本实用新型实施例还提供了一种电子设备，包括上述所述的电子设备触摸屏的安装结构。
工业实用性
本实用新型实施例的电子设备触摸屏的安装结构，通过电子设备壳体上的安装框架与触摸屏本体固定连接，并在安装框架上开设多个通孔，以及用于避免溢胶且与通孔相通的沉槽，使得填充在通孔和沉槽内的粘接剂将安装框架和触摸屏本体粘接连接，有效避免了溢胶现象，增加了触摸屏本体和电子设备壳体之间的粘接力，且降低了维修时的拆解难度和清理难度。
