具体实施方式
为使本领域的技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明所提供的一种显示装置及其壳体组件做进一步详细描述。
参阅图1，本发明提供的显示装置的壳体组件10实施例包括中框11、上框12及下框13。
共同参阅图2，中框11包括环形设置的第一侧壁111，该第一侧壁111上设置有第一卡和部112。
可选的，第一卡和部112为卡勾，该卡勾设置于第一侧壁111的内侧并外露于第一侧壁111，在其他实施例中，第一卡和部112也可以是卡槽。
其中，第一卡和部112的卡勾包括第一倾斜导引面1121以及卡合面1122。
进一步地，中框11上还设置有第一台阶结构113，具体地，中框11的内侧在顶端的位置设置有第一台阶结构113。
上框12包括设置有开口区域121的顶壁122及与顶壁122连接的第二侧壁123。
其中，第二侧壁123上设置有第二卡和部124。
可选的，第二卡和部124为与第一卡和部112配合的卡槽，在其他实施例中，当第一卡和部112为卡槽时，第二卡和部124则为与卡槽配合的卡勾。
进一步地，第二侧壁123的端部还设置有与第一倾斜引导面1121配合的第二倾斜导引面1231。
第二侧壁123上还设置有第二台阶结构125，具体地，在第二侧壁123的外侧设有第二台阶结构125，且第二台阶结构125可与第一台阶结构113相互契合。
共同参阅图3，下框13包括底壁131，底壁131上设置有止挡件132。
其中，止挡件132的尺寸在顶端到与底壁131连接的底端的方向上逐渐增大，例如，止挡件132的外侧面垂直于底壁131，止挡件132的内侧面倾斜于底壁131，且与底壁131之间的夹角为钝角。
共同参阅图1至图4，当本实施例的壳体组件10在装配时，可先将上框12在如图2所示的由上至下的方向装入中框11，即将第二侧壁123在该方向插入中框11内，在该插入过程中，第二侧壁123上的第二倾斜导引面1231与第一卡和部112的卡勾在第二侧壁123的插入方向设置的第一倾斜导引面1121相配合，以使得第二侧壁123在第一倾斜导引面1121和第二倾斜导引面1231的作用下发生弹性形变，进而使得第一卡和部112的卡勾沿第二侧壁123的侧面相对移动直至如图4所示的位于第二卡和部124的卡槽内部，并由背离插入方向的卡合面1122保持在第二卡和部124的卡槽内时，第二侧壁123恢复至未发生弹性形变的状态，位于第一侧壁111的内侧且与第一侧壁111呈相对设置，以使 得中框11与上框12通过第一卡合部112和第二卡和部124卡扣连接，此时，中框11上的第一台阶结构113与第二侧壁123上的第二台阶结构125相互契合，使得第二侧壁123停止向下装入，而位于第二卡和部124的卡槽内部的卡合面1122则会使得第二侧壁123不会向上移动，保证了中框11与上框12在上下方向的卡扣可靠性。
然后，将下框13在图3所示的从下向上的方向装入中框11，以使得下框13与中框11相连接，进而使得在装入完成之后，如图4所示，下框13的底壁131与上框12的顶壁122呈相对设置，底壁131上的止挡件132位于第二侧壁123远离第一侧壁111的一侧并与第二侧壁123的相邻侧面彼此平行，而且止挡件132与第一侧壁111之间的距离设置成防止第一卡和部112与第二卡和部124彼此脱开，该设置可以包括两种情况：其中一种为止挡件132弹性抵靠于第二侧壁123远离第一侧壁111的一侧，另一种为止挡件132与第二侧壁123间隔设置，二者的间隔距离设置成在第二侧壁123相对第一侧壁111产生由间隔距离所限定的最大形变时，第一卡合部112和第二卡合部124仍保持配合状态，这两种情况均可以保证上框12与中框11在图4所示的左右方向的卡扣可靠性，结合上述的保证了上框12与中框11在上下方向的卡扣可靠性，进而在整体上保证了上框12与中框11的卡扣可靠性。
其中，在一应用实施例中，上述的下框13与中框11的连接方式亦可是卡扣连接。

其中，第三卡和部114的卡勾包括第三倾斜导引面1141及第二卡合面1142。
进一步地，第一侧壁111还设有第三台阶结构115，具体地，在第一侧壁111的内侧在底端位置设置有第三台阶结构115。
下框13进一步包括与底壁131连接的第三侧壁133，第三侧壁133上设置有第四卡和部134，可选的，第四卡和部134为与第三卡和部114 的卡勾配合的卡槽，在其他实施例中，若第三卡和部114为卡槽，则第四卡和部134为与该卡槽配合的卡勾。
其中，第三侧壁133的顶部设置有与第三倾斜导引面1141配合的第四倾斜导引面1331。
进一步地，下框13还设置有第四台阶结构135，可选的，在下框13的外侧底端的位置设置有第四台阶结构135，且第四台阶结构135可与第三台阶结构115相互契合。
共同参阅图1、图5及图6，在将下框13装入中框11中时，可在如图5所示的由下至上的方向将下框13装入中框11，即将第三侧壁133插入中框11，在该插入过程中，第三侧壁133上的第四倾斜导引面1331与第三卡和部114的卡勾上的第三倾斜导引面1141相配合，以使得第三侧壁133在第三倾斜导引面1141与第四倾斜导引面1331的作用下发生弹性变形，进而使得第三卡和部114的卡勾沿第三侧壁133的侧面相对移动直至如图6所示的位于第四卡和部134内部，并由背离该插入方向的第二卡合面1142保持在第四卡和部134的卡槽内时，第三侧壁133恢复至未发生弹性变形的状态，位于第一侧壁111的内侧且与第一侧壁111呈相对设置，以使得中框11与下框13通过第三卡和部114与第四卡和部134卡扣连接，此时，中框11上的第三台阶结构115与下框13上的第三台阶结构135相互契合，使得下框13停止装入，下框13与中框11装配结束，且在装配结束之后，使得上述的止挡件132位于第二侧壁123远离第一侧壁111的一侧，且止挡件132与第一侧壁111之间的距离设置成防止第一卡合部112和第二卡合部124彼此脱开。
参阅图7，本发明提供的显示装置实施例包括上述的壳体组件20及显示屏(未标示)。
其中，显示屏由顶壁222压持固定与底壁(图中未显示)上，且显示屏的显示区域至少部分经开口区域221外露以供观看或使用。
在一应用场景中，通过遥控器控制无人机飞行，本实施例中的显示装置固定于遥控器上，该无人机具有航拍功能，在遥控器控制无人机航拍的同时，将航拍内容显示于该显示装置的显示屏上供操作者观看，为 操作者提高航拍体验。
区别于现有技术，本发明通过上框的第二侧壁位于中框的第一侧壁内侧与第一侧壁卡扣连接，并在下框的底壁上设置止挡件，该止挡件设置于第二侧壁远离第一侧壁的一侧，且该止挡件与第一侧壁之间的距离设置成防止第一侧壁和第二侧壁卡扣连接彼此脱开的方法，使得上框与中框的卡扣连接不会彼此脱开，保证了上框与中框的卡扣可靠性，且与现有技术中通过螺栓连接上框与中框防止两者的卡扣连接彼此脱开的方法相比，在外观上更加美观。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
