The invention relates to a double-end pantograph structure for a new energy heavy truck, and belongs to the technical field of new energy heavy truck charging, the double-end pantograph structure comprises a frame, two lifting mechanisms and two pantograph heads, the bottom ends of the two lifting mechanisms are adjacently fixed on the frame; and the two electric shock bow heads are respectively fixed at the top ends of the two lifting mechanisms. The two lifting mechanisms are designed to drive the two electric shock bow heads to ascend and descend correspondingly, and the two electric shock bow heads are electrically connected with the positive electrode line and the negative electrode line of the power grid charging power line and the positive electrode charging line and the negative electrode charging line of the new energy heavy truck power supply device correspondingly, so that a complete power-on loop is formed; the new energy heavy truck can be prevented from being additionally provided with parts to be connected with the ground, and the driving safety of the new energy heavy truck is improved; meanwhile, the two pantograph heads independently ascend and descend and can adapt to the situation that the vertical distance between a positive electrode wire and a negative electrode wire in a contact net is large, and therefore the adaptability of the double-head pantograph structure is improved.

    本发明涉及一种新能源重卡用双头受电弓构型,属于新能源重卡充电技术领域,包括:框架、两个举升机构及两个触电弓头,两个举升机构的底端相邻固定在框架上;两个触电弓头分别固定在两个举升机构的顶端。本发明通过设计两个举升机构分别带动连个触电弓头上升下降,由于两个触电弓头分别与电网充电电源线的正极线、负极线和新能源重卡供电装置的正极充电线、负极充电线电性连接,构成了一个完整的通电回路,可以避免新能源重卡额外增加部件与大地相连,提高新能源重卡的行驶安全性;同时,两个触电弓头独立升降,可以适应接触网中正极线和负极线上下间距较大的情况,从而提高双头受电弓构型的适应性。
