Abstract

本发明公开了一种汽车仪表后盖与灯箱架的安装结构，包括后盖与灯箱架，两者通过螺钉固连在一起，所述后盖的上端面靠内边缘位置处设置有等厚、等高的环向凸台，所述灯箱架的下端面靠内边缘位置处设置有环向缺槽，环向凸台位于环向缺槽内，且环向凸台的顶面与环向缺槽的顶面之间留有间隙，环向凸台的外壁与环向缺槽的外壁之间留有间隙。结合环向凸台和环向缺槽进行安装限位，保证了装配后外壁的一致性，并提高后盖的强度，防止后盖变形；同时环形凸起与环向缺槽提高了安装后的密闭性，既能防止灰尘进入，又能有效防止静电进入灯箱架，干扰PCB电路板和液晶屏的正常工作。

Description

汽车仪表后盖与灯箱架的安装结构
技术领域
本发明涉及汽车零部件技术领域，具体涉及一种汽车仪表后盖与灯箱架的安装结构。
背景技术
在灯箱架内安装有液晶屏和PCB电路板，后盖的上端面与灯箱架的下端面贴合在一起，再结合螺钉紧固在一起。后盖与灯箱架的安装缺少限位结构，安装不方便；后盖为薄板，安装后容易发生变形；后盖与灯箱架的安装密闭性差，灰尘和静电容易进入灯箱架内，干扰液晶屏和PCB电路板的正常工作。
发明内容
本发明旨在解决仪表后盖与灯箱架安装不便、密封差，无法阻止静电干扰、灰尘进入及后盖变形的问题。
为此，本发明所采用的技术方案为：一种汽车仪表后盖与灯箱架的安装结构，包括后盖与灯箱架，两者通过螺钉固连在一起，所述后盖的上端面靠内边缘位置处设置有等厚、等高的环向凸台，所述灯箱架的下端面靠内边缘位置处设置有环向缺槽，环向凸台位于环向缺槽内，且环向凸台的顶面与环向缺槽的顶面之间留有间隙，环向凸台的外壁与环向缺槽的外壁之间留有间隙。
作为上述方案的优选，所述环向凸台的外壁顶部倒角，防止安装时尖角碰到环向缺槽。
本发明的有益效果：结合环向凸台和环向缺槽进行安装限位，保证了装配后外壁的一致性，并提高后盖的强度，防止后盖变形；同时环形凸起与环向缺槽提高了安装后的密闭性，既能防止灰尘进入，又能有效防止静电进入灯箱架，干扰PCB电路板和液晶屏的正常工作。
附图说明
图1为本发明的结构示意图。
图2为图1的A-A剖视图。
图3为图2的B部放大图。
图4为图1中后盖的结构示意图。
具体实施方式
下面通过实施例并结合附图，对本发明作进一步说明：
结合图1—图4所示，仪表后盖1与灯箱架2通过螺钉固连在一起，相应地，在后盖1、灯箱架2的外壁上设置有供螺钉通过的安装凸台。
后盖1的上端面靠内边缘位置处设置有等厚、等高的环向凸台1a，灯箱架2的下端面靠内边缘位置处设置有环向缺槽2a。环向凸台1a位于环向缺槽2a内，且环向凸台1a的顶面与环向缺槽2a的顶面之间留有间隙，环向凸台1a的外壁与环向缺槽2a的外壁之间留有间隙。增设环向缺槽2a和环向凸台1a密闭结构，能防止灰尘进入，并在一定程度上起到安装限位、防变形的作用；同时，在环向凸台的基础上增加了间隙限定，外部的静电传递到仪表内时，路线大大延长，显示屏及电路板受静电干扰的可能性大大降低(静电传递的路线如图3中箭头所示)。
最好是，环向凸台1a的外壁顶部倒角1b。
