The invention relates to a traction trailer capable of solving the problems of slow charging and battery replacement of an electric automobile and difficulty in rescue. The traction trailer mainly comprises a battery, an inversion voltage regulating device, a bearing linkage brake wheel, an anti-collision device, a linkage brake lamp, a license plate display screen, a charged freewheeling vehicle connecting and fixing device, a power supply connecting wire and the like. Power support is provided for the front vehicle by means of power traction of the front vehicle. Or the front vehicle is charged while the power is provided for the front vehicle for endurance. And under the condition that the appearance of the original front vehicle is not changed basically, another creative continuous power and energy supplement mode is provided for the current electric vehicle.
本发明是一种解决电动汽车充电换电慢及救援困难的牵引拖挂车,主要由电池、逆变调压装置、承载联动刹车轮、防撞装置、联动刹车灯、及车牌显示屏和被充电续电车连接固定装置、电源连接线等组成。依靠前车动力牵引,为前车提供电力支持。或实现边给前车提供电力续航边给前车充电。在基本上不改变原前车外观的情况下,为现在的电动汽车提供了另一种开创性的续电补能方式。
