The invention relates to the technical field of electric automobiles, and discloses an electrorheological fluid-based electric vehicle gear control mechanism. The gear control mechanism comprises a driving shaft and a shell, wherein a conveying belt is in transmission connection with the outer side of the driving shaft, a driven shaft is in transmission connection with the side, away from the driving shaft, of the conveying belt, and a rotating disc is fixedly connected to the back of the driven shaft. According to the electrorheological fluid-based electric vehicle gear control mechanism, when a vehicle runs rapidly, the driving shaft drives the driven shaft to rotate rapidly at the moment, the rotating disc is further made to rotate rapidly, a first metal ball makes contact with a secondmetal ball at the moment, the two ends of an electrorheological fluid are powered on at the moment, and therefore the effect that the electrorheological fluid is changed into a solid from a liquid isachieved; and when the vehicle runs quickly, the electrorheological fluid is changed into a solid from a liquid, and at the moment, a limiting rod is clamped in a groove, so that a gear rod cannot rotate, a handle cannot be wrenched, and the effect of preventing a driver from suddenly changing gears to damage the vehicle in the quick running process of the vehicle is achieved.
本发明涉及电动汽车技术领域,且公开了一种基于电流变体的电动汽车档位控制机构,包括主动轴和外壳,所述主动轴的外侧传动连接有传送带,所述传送带远离主动轴的一侧传动连接有次动轴,所述次动轴的背部固定连接有转动盘。该基于电流变体的电动汽车档位控制机构,当车辆快速行驶时,此时主动轴带动次动轴快速转动,进一步使得转动盘快速转动,此时金属球一与金属球二接触,此时电流变体的两端通电,从而达到了使电流变体由液体变为固体的效果。当车辆在快速行驶时,电流变体会由液体变为固体,此时限位杆卡在凹槽内部,使得档位杆无法转动,进一步使得把手无法扳动,从而达到了防止车辆在快速行驶过程中驾驶员突然变换档位损坏车辆的效果。
