The invention discloses a dual-purpose trailer for a standing posture and a lying posture, which comprises a loading bottom plate and a frame, the frame comprises a traction rod and a supporting frame, the supporting frame comprises two symmetrically-arranged arc-shaped rods, and the lower ends of the two arc-shaped rods are connected with the loading bottom plate through a folding mechanism and gradually rise and extend to form an upward arch. The two arc-shaped rods gradually draw close in the upward extending process and are connected at the top ends; the traction rod is arranged at the upper end of the supporting frame, a force application end is formed at the upper end of the traction rod, and the force application end bends and extends in the direction away from the loading bottom plate. The dual-purpose trailer is simple and stable in overall structure, easy to store and convenient to use; by optimizing the structure of the trailer frame, the trailer can meet standing traction and prone traction at the same time, and the applicability is higher; the supporting frame is combined with ergonomics and adopts the optimal size and radian, traction can be achieved in the normal advancing process of a traction person, and labor saving and convenience are achieved.

    本发明公开一种站姿卧姿两用拖车,其包括装载底板和车架,所述车架包括牵引杆及支撑架,支撑架包括两根对称设置的弧形杆,两根弧形杆下端通过折叠机构与装载底板连接,并逐渐上扬延伸形成向上的拱形,两根弧形杆上扬延伸过程中逐渐靠拢,并在顶端连接;牵引杆设于支撑架的上端,所述牵引杆的上端成型有施力端头,施力端头朝向远离装载底板的方向弯曲延伸。本发明整体结构简洁稳定,易收纳,使用便捷;通过优化车架的结构,能够使拖车同时满足站姿牵引和卧姿牵引,适用性更强;支撑架结合人体工学采用了最佳尺寸和弧度,使牵引者在正常行进的过程中即能实现牵引,省力便捷。
