具体实施方式
下面结合附图和具体实施例对本发明的技术方案作进一步详细的说明，本发明提出一种空调室内机的实施例，参照图1-图7所示，包括罩壳1和 骨架2，本实施例中的罩壳1可以为由左侧板、右侧板、壳体和面板一体成型的或由左侧板、右侧板、壳体和面板别连接成型均可，在此不做具体限制。罩壳1上设置有截面为多边形的卡设柱3，卡设柱3的截面形状可以为菱形、五边形或六边形等，在此不做具体限制，通过多边形的卡设柱3和设置在骨架2上与其适配的弹性的卡槽4进行配合，可使卡设柱3和卡槽4之间为多个面接触配合，可进行完全适配固定，增强了卡设柱3和卡槽4之间卡接配合的稳定性；同时由于卡设柱3和卡槽4之间为多边形配合，多边形的各个面相互之间可进行约束限位，实现对卡设柱3的周向限位，可以防止卡设柱3在卡槽4内转动，如若本实施例中的卡设柱3采用圆形截面的，则与卡槽4配合时在沿卡槽4周向转动的自由度没有受到限制则可能会产生沿卡槽4周向转动的现象，导致罩壳1和骨架2之间的配合不够牢固，稳定性差，罩壳1通过卡设柱3扣压进卡槽4内实现与骨架2的卡设固定。
进一步的，所述卡槽4为弹性卡槽，卡槽4的开口小于所述卡设柱3的最小轮廓直径。在卡设柱3受到按压力卡入到卡槽4内时，会施加作用力给开口，开口具有弹性，受压后产生弹性变形，卡设柱3卡装进卡槽4内部，由于施加在开口上的作用力消除，开口恢复变形，口径变小，小于卡设柱3的最小轮廓直径，将卡设柱3限位在卡槽4内部，有效的防止了卡设柱3的脱出。
进一步的，本实施例中还包括有用于支撑所述卡槽4的支撑组件5，支撑组件5固定在骨架2上，所述支撑组件5包括2个卡槽支撑筋51，在所述2个卡槽支撑筋51之间设置有悬空连接在两者之间的所述卡槽4，卡槽4为可以与卡设柱3适配的截面形状。通过卡槽支撑筋51实现对卡槽4的支撑固定。
为方便卡设柱3的安装装配，在所述卡槽支撑筋51与卡槽4之间设置有导向结构6，所述导向结构6包括依次连接的第一导向面61和第二导向面62，所述第一导向面61与所述卡槽支撑筋51连接，所述第二导向面62与所述卡槽4连接。卡设柱3在安装时，在距离卡槽4较远距离时，可先沿第一导向面61进入，然后进入到第二导向面62内，通过第二导向面62进入到卡槽4内，实现装配，通过导向结构6，可使卡设柱3实现快速装配，提高了装配效率，缩短了前期的预装配时间。
优选的，所述第一导向面61与所述卡槽支撑筋51之间具有第一夹角， 所述第一夹角角度为45-90度，所述第一导向面61与所述第二导向面62之间具有第二夹角，所述第二夹角角度为：120-160度。
进一步的，本实施例的所述支撑组件5至少设置2组，沿所述骨架2的长度方向设置。卡槽4也对应所述支撑组件5设置，卡设柱3的组数也对应卡槽4设置，通过设置多组卡槽4和卡设柱3，可确保罩壳1和骨架2之间卡接固定的牢固性。
为实现对卡设柱3的定位固定，本实施例中还包括有用于固定所述卡设柱3的固定组件7，所述固定组件7固定在所述罩壳1上，所述固定组件7包括第一卡设筋板71、第二卡设筋板72和第三卡设筋板73，所述第一卡设筋板71固定在所述卡设柱3的底端，所述第二卡设筋板72和所述第三卡设筋板73分别固定在所述卡设柱3的两端。
进一步的，所述卡槽4底面为从骨架2的前端到骨架2的后端高度逐渐变高的斜面。为实现与卡槽4的适配，所述卡设柱3也采用倾斜设置，即卡设柱3与所述罩壳1侧面间具有夹角，所述夹角角度为30-60度。第一卡设筋板71采用可与所述卡设柱3倾斜设置适配的三角形筋板。采用卡设柱3和卡槽4均倾斜设置的方式，可便于两者装配，且采用倾斜设置还可使两者之间沿斜面产生相互作用力，使两者装配更加牢固。
为方便出模成型，优选的，所述卡槽4的侧面为向外侧倾斜的倾斜面。
进一步的，所述第三卡设筋板73为U型支撑筋，所述罩壳1上与所述U型支撑筋位置对应处设置有开口。通过开口可方便看到卡设柱3和卡槽4的装配情况。
优选的，本实施例的第一卡设筋板71、第二卡设筋板72、第三卡设筋板73和卡设柱3与所述罩壳1为一体注塑成型件，所述卡槽4、卡槽支撑筋51和骨架2为一体注塑成型件。
以上实施例仅用以说明本发明的技术方案，而非对其进行限制；尽管参照前述实施例对本发明进行了详细的说明，对于本领域的普通技术人员来说，依然可以对前述实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或替换，并不使相应技术方案的本质脱离本发明所要求保护的技术方案的精神和范围。
