A six-linkage telescopic dining car comprises a bottom frame, a height telescopic frame, a top frame, a single-side six-linkage expansion structure and a driving assembly. The single-side six-linkage expansion structure comprises a side bottom surface expansion assembly, a side vertical surface expansion assembly and a side top surface expansion assembly. The height telescopic frame can ascend or descend in the height direction, the top frame is lifted through the height telescopic frame, and space expansion is achieved in the height direction. And the single-side six-linkage expansion structure can perform space expansion in the two side directions relative to the bottom frame after being expanded and opened. The driving assembly is used for providing power when the structure is unfolded or folded. According to the invention, six linked unit structures, especially sliding structures of the side top surface expansion assembly, are innovatively arranged, so that when the side bottom surface expansion assembly is unfolded, the side vertical surface expansion assembly can be driven to act to provide allowance for complete unfolding of the side bottom surface expansion assembly. The device is reasonable in structural design, easy and convenient to operate, flexible to move, high in maneuverability and wide in application range.

    一种六联动可伸缩餐车,包括底架、高度伸缩架、顶架、单侧六联动拓展结构以及驱动组件。单侧六联动拓展结构包括有侧底面拓展组件、侧立面拓展组件以及侧顶面拓展组件。高度伸缩架可在高度方向上抬升或者下降,通过高度伸缩架将顶架抬升,在高度方向上实现空间拓展。单侧六联动拓展结构伸展打开后能够相对于底架在两侧方向上进行空间拓展。驱动组件则用于在结构展开或者收纳时提供动力。本发明创新性地设置了六个联动的单元结构,尤其是侧顶面拓展组件的滑动结构,能够在侧底面拓展组件展开时,带动侧立面拓展组件动作为侧底面拓展组件的完全展开提供余量。本发明结构设计合理、操作简单方便、移动灵活具备高机动性,其用于也十分广泛。
