The invention discloses a car roof LED display screen box structure and a car roof LED display screen, wherein the car roof LED display screen box structure is used for fixing a display panel and comprises a cavity assembly and a bayonet assembly. The cavity assembly comprises a first cavity and a second cavity, one end of the first cavity and one end of the second cavity are in butt joint and arearranged in a stacked mode, and the two ends of the display panel are connected with the side surface of the first cavity and the side surface of the second cavity respectively. The bayonet assemblyis used for being detachably connected with the first cavity and the second cavity, the bayonet assembly comprises a clamping block arranged in the first cavity in a protruding mode and a clamping groove formed in the second cavity and arranged corresponding to the clamping block, the clamping block is clamped into the clamping groove, and the two opposite side surfaces of the clamping block abutagainst the two side groove walls of the clamping groove respectively. The strength of the car roof LED display screen box structure can be improved, impact and jolt borne by the car roof LED displayscreen box structure are effectively resisted, impact and jolt conducted to the display panel by the car roof LED display screen box structure are reduced, and thus the reliability of the display panel is improved.

    本发明公开了一种车顶LED显示屏箱体结构以及车顶LED显示屏,车顶LED显示屏箱体结构用于固定显示面板,其包括腔体组件和卡口组件。腔体组件包括第一腔体和第二腔体,第一腔体的一端与第二腔体的一端对接且层叠设置,显示面板的两端分别连接第一腔体的侧表面和第二腔体的侧表面。卡口组件用于可拆卸地连接第一腔体和第二腔体,卡口组件包括凸设于第一腔体的卡块和开设于第二腔体且对应卡块设置的卡槽,卡块卡入卡槽,且卡块相背设置的两侧表面分别抵接卡槽的两侧槽壁。本申请可以提高车顶LED显示屏箱体结构的强度并有效抵抗车顶LED显示屏箱体结构受到的冲击和颠簸,并降低其传导至显示面板的冲击和颠簸,从而提高显示面板的可靠性。
