An anti-falling device of a two-wheeled electric vehicle is structurally formed by connecting electromagnetic valves, a rear supporting assembly and a contact switch. The electromagnetic valves are improved from normally-closed electromagnetic valves in direct-acting electromagnetic valves; the rear supporting assembly is improved by selecting a belt wheel bracket in the prior art; the electromagnetic valves are respectively arranged below a rear bottom fork or a rear bumper of the electric vehicle, and stay wires with the same length are respectively connected between the front ends of valverods of the two electromagnetic valves and the rear supporting assembly, so that a synchronous linkage connecting mechanism is formed between the rear supporting assembly and the electromagnetic valves; the contact switch is mounted on the front side of a rear wheel brake swing arm, is connected in series with a circuit for supplying power to the two electromagnetic valves and the storage batteryof the electric vehicle, and can control the two electromagnetic valves to synchronously open and close; under the condition that a rear wheel brakes, the contact switch can be touched to connect thecircuit of the electromagnetic valves, so that the valve rods of the electromagnetic valves are started to pull the rear supporting assembly to move downwards until two trundles are grounded, the trundles play a role in supporting and balancing the left-right swing instability of the vehicle body, and the accident risk that the vehicle body is prone to falling down is eliminated.
一种两轮电动车的防摔倒装置,结构由电磁阀,后支撑总成,触点开关相连组成;电磁阀采用直动电磁阀中的常闭式电磁阀改进完成;后支撑总成选用现有技术中的带轮支架改进完成;在电动车的后平叉或后保险杠的下面分别设置电磁阀,在两套该电磁阀的阀杆前端和后支撑总成之间分别连接一段等长的拉线,以此使后支撑总成和电磁阀之间形成同步联动连接机构;在后轮刹车摆臂的前侧安装触点开关,触点开关串接在两个电磁阀与电动车蓄电池供电的电路上,且能够控制两个电磁阀的同步启、闭运行;在后轮刹车的情况下能够触碰触点开关接通电磁阀的电路,从而起动电磁阀的阀杆牵引后支撑总成向下运动至两个脚轮接地,脚轮对车身的左右摆动不稳起到了支撑平衡的作用,消除了容易摔倒的事故隐患。
