The invention discloses an active driving joint and an unfolding device. The active driving joint comprises a fixed seat; a guide rod is arranged on the fixed seat in a penetrating manner; the guide rod and the fixed seat are arranged in a relative sliding manner; a first coil is arranged on the guide rod; a second coil matched with the first coil is arranged on the fixed seat; two rotating seats are hinged to the fixed seat; the two rotating seats are symmetrically arranged along the central axis of the guide rod; a connecting rod is hinged to the rotating seat; and the other end of the connecting rod is hinged to one end of the guide rod. By controlling the current direction and on-off of the first coil and the second coil, the direction and on-off control of electromagnetic force can be realized, so that the joint can be controlled to finish unfolding and folding actions, and the whole active driving joint is simple in structure, low in cost, convenient to operate and high in stability.
本发明公开了一种有源驱动关节及展开装置,包括:固定座;所述固定座上穿设有导向杆;所述导向杆与所述固定座相对滑动设置;所述导向杆上设有第一线圈;所述固定座上设有与所述第一线圈相配合的第二线圈;所述固定座上铰接有两个旋转座;两个所述旋转座沿所述导向杆中轴线对称设置;所述旋转座上铰接有连杆;所述连杆另一端铰接于所述导向杆一端。本发明通过控制第一线圈和第二线圈的电流方向和通断,可以实现电磁力的方向和开关控制,从而可以控制关节完成张开和折叠动作,整个有源驱动关节结构简单、成本低、操作便捷且稳定性高。
