The invention relates to a double-end pantograph structure for online charging of 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, a lifting mechanism, a cross rod and two pantograph heads, the bottom end of the lifting mechanism is fixed on the frame; the cross rod is vertically fixed at the top end of the lifting mechanism; and the two electric shock bow heads are fixed on the cross rod at an interval through an insulator 1. According to the invention, the two electric shock pantograph heads are fixed on the cross rod at intervals, and the two electric shock pantograph heads are electrically connected with the positive wire and the negative wire of the power grid charging power line and the positive charging wire and the negative charging wire of the new energy heavy truck power supply device respectively, so that a complete power-on loop is formed; the situation that additional parts of the new energy heavy truck are connected with the ground can be avoided, and therefore the running speed and running safety of the new energy heavy truck are improved.

    本发明涉及一种新能源重卡在线充电用双头受电弓结构,属于新能源重卡充电技术领域,包括:框架、升降机构、横杆及两个触电弓头,升降机构的底端固定在框架上;横杆垂直固定在升降机构的顶端;两个触电弓头通过绝缘子一间隔固定在横杆上。本发明通过在横杆上间隔固定两个触电弓头,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,从而提高新能源重卡的行驶速度和行驶安全性。
