The invention provides a contact rod folding and unfolding structure based on a road contact network, and belongs to the technical field of electric vehicles. According to the technical scheme, the contact rod is rotationally connected to the rotating disc through the horizontal shaft, and the height adjusting mechanism is connected between the rotating disc and the contact rod; the height adjusting mechanism can directly adopt a cylinder body, and the height adjustment is realized through the telescopic movement of the cylinder body; the sliding block and the connecting rod can also be used for transmission, the linear driving mechanism is used for pushing the sliding block to move horizontally, the contact rod is driven to do pitching motion, and therefore the height adjusting purpose is achieved. The lifting mechanism and the rotating mechanism which move synchronously are designed for the double contact rods, and free butt joint of the contact rods and the overhead contact line system in multiple directions can be achieved through combined movement of the lifting mechanism and the rotating mechanism. According to the clutch mode, the two modes of cylinder body driving and sliding block-connecting rod driving are designed, and good stability is achieved; in the angle adjusting mode, the rotating disc is adopted for driving, and the orientation of the contact rod can be freely adjusted. The device is completely mechanically driven, and the automation degree is high.
本发明提供了一种基于道路接触网的接触杆收放结构,属于电动车辆技术领域。此技术方案将接触杆以水平轴转动连接在转盘上,在转盘和接触杆之间连接有高度调节机构;所述高度调节机构可直接采用缸体,通过缸体的伸缩运动实现高度调节;也可利用滑块、连杆传动,利用线性驱动机构推动滑块平移,带动接触杆做俯仰运动,从而达到高度调节目的。本发明为双接触杆设计了同步运动的升降机构和旋转机构,二者的复合运动可实现接触杆在多方向下与架空接触网的自由对接。在离合方式上,本发明设计了缸体驱动和滑块‑连杆驱动两种模式,具有良好的稳定性;在角度调节方式上,采用转盘驱动,可自由调节接触杆朝向。本发明完全由机械驱动,自动化程度高。
