具体地，限位结构具有弹性，且限位结构的形状与凹槽的形状相匹配， 如限位结构的宽度小于或等于凹槽的宽度，限位结构的深度小于或等于凹槽的深度。在防尘组件装配于中框内时，限位结构与凹槽相配合，限位结构卡接于中框上的凹槽中，形成稳定结构，以使得防尘组件固定于中框上。
具体地，限位结构可以为一个平滑的曲面，并且该限位结构可以为支架的一部分，也可以是装设在支架上的外部结构。
可选地，限位结构与支架可以是一体成型，也可以直接焊接或粘接于支架的表面，还可以通过其他组件连接于支架的表面，在此不作具体限定。
可选地，该限位结构还可以是凸块结构，该凸块结构可以为圆柱体凸块、圆锥体凸块或球体凸块，在此不作具体限定。并且，中框通道内壁上的凹槽的形状与该凸块结构的形状相对应。
进一步地，该限位结构可以由硅胶或者其他弹性材料组成，以使得该限位结构具有良好的弹性效果。该限位结构与中框上的凹槽形成配合结构，以使得防尘组件固定在上述中框的通道内的情况下，限位结构在弹力的作用下有朝向远离支架的方向运动的趋势并卡接于上述凹槽当中，且该限位结构与该凹槽相抵并过盈配合，避免限位结构与凹槽之间留有空隙，提升该设备壳体的防水效果。
如图1所示，第一防尘组件10包括第一限位结构101a和第二限位结构101b，中框30的通道301上包括第一凹槽301a和第二凹槽302b；第一限位结构101a卡接于第一凹槽301a，且第一限位结构101a在弹力的作用下与第一凹槽301a相抵并过盈配合，第二限位结构101b卡接于第二凹槽301b，且第二限位结构101b在弹力的作用下与第二凹槽301b相抵并过盈配合。
进一步地，第一凹槽301a垂直于上述通道301在中框30上的延伸方向的宽度，与第一限位结构101a垂直于上述通道301在中框30的延伸方向的宽度相等，以使第一限位结构101a能完全充盈第一凹槽301a；中框30上的第二凹槽301b垂直于上述通道301在中框30上的延伸方向的宽度，与第二限位结构101b垂直于上述通道301在中框30上的延伸方向的宽度 相等，以使第二限位结构101b能完全充盈第二凹槽301b，减少进液路径，降低设备壳体的进液风险。
如图6所示，第二防尘组件20包括第三限位结构201a和第四限位结构201b，中框30的通道301上包括第一凹槽301a和第二凹槽302b；第三限位结构201a卡接于第一凹槽301a，且第三限位结构201a在弹力的作用下与第一凹槽301a相抵并过盈配合，第四限位结构201b卡接于第二凹槽301b，且第四限位结构201b在弹力的作用下与第二凹槽301b相抵并过盈配合。
进一步地，第一凹槽301a垂直于上述通道301在中框30上的延伸方向的宽度，与第三限位结构201a垂直于上述通道301在中框30的延伸方向的宽度相等，以使第三限位结构201a能完全充盈第一凹槽301a；中框30上的第二凹槽301b垂直于上述通道301在中框30上的延伸方向的宽度，与第四限位结构201b垂直于上述通道301在中框30上的延伸方向的宽度相等，以使第四限位结构201b能完全充盈第二凹槽301b，减少进液路径，降低设备壳体的进液风险。
在本申请的实施例中，防尘组件的支架设有限位结构，中框设有凹槽，限位结构与凹槽相配合，以使防尘组件固定于所述中框的通道中，并且该防尘组件与中框通道过盈配合，减少了设备的进液路径，提升电子设备的防水效果。
根据本申请的一些实施例，还提供了一种电子设备，该电子设备包括上述实施例中的设备壳体。
在本申请实施例中，防尘组件的支架设有限位结构，中框设有凹槽，限位结构与凹槽相配合，以使防尘组件固定于所述中框的通道上，减少了进液路径，提升电子设备的防水效果。
