The invention discloses an electric direct-drive small loading military transfer trolley which comprises a supporting frame, moving wheels, a bearing support, a middle storage plate, a folding bearing plate, a hollow stepping motor and a battery protection frame. The folding type bearing plates are installed on the two sides of the bearing support correspondingly and distributed on the two sides of the middle storage plate, and when the folding type bearing plates are folded, the folding type bearing plates are folded towards the middle storage plate and placed on the upper end face of the middle storage plate, so that telescopic folding is achieved; the hollow stepping motor drives the bearing support and the linkage connecting rod to move downwards through the lifting screw rod, meanwhile, the bearing support drives the battery protection frame to rotate towards the lower portion of the outer side through the linkage connecting rod, and therefore the whole structure sinks and is located on the lower side between the two moving wheels, folding, sinking and shrinking of the whole structure are achieved, and meanwhile through gravity operation, the whole structure can be folded. And the supporting column can rotate on the side part of the battery protection frame and is supported on the ground, so that automatic supporting is realized, the convenience degree of independent operation is improved, and the stability is improved.
本发明公开了一种电动直驱小型载重军用转运车,包括支撑架、移动轮、承载支架、中间收纳板、折叠式承载板、中空步进电机、电池保护框;本发明在承载支架的两侧分别安装折叠式承载板,折叠式承载板分布于中间收纳板的两侧,折叠时,折叠式承载板向中间收纳板折叠并放置于中间收纳板的上端面,如此实现伸缩折叠,中空步进电机通过升降螺杆驱动承载支架和联动连杆向下移动,同时承载支架通过联动连杆带动电池保护框向外侧下方转动,如此实现整个结构的下沉,并位于两个移动轮之间的下侧,实现了整个结构的折叠下沉收缩,同时通过重力作业,支撑柱会在电池保护框侧部转动并支撑于地面上,如此实现自动支撑,提高独立作业的便利程度,提高平稳性。
