The automobile fuel is based on diesel, gasoline or natural gas. The domestic petrochemical energy source mainly relies on imports, and the petrochemical energy supply is becoming increasingly tense. In response to the current shortage of petrochemical energy, with the strong support of the government, the pace of development of new energy vehicles at home and abroad has gradually accelerated. The total number of hybrid and pure electric vehicles has grown rapidly, and the demand for emergency rescue services for electric vehicles has gradually emerged. There is an urgent need for electric vehicle emergency rescue vehicles with professional functions to meet the growing market demand. At the same time, as a supporting device, the charging power supply output device charging gun and cable retracting device also have an urgent need.
使用充电车给电动汽车充电与使用充电桩充电设备所处位置有所不同且不固定。往往由于道路、停车场条件限制和各型电动汽车的充电插座所处的位置不同，充电电缆长度较固定式充电桩充电方式增加了许多，一般需要10～15米。这样有必要在充电车上设置电缆绞盘。充电车工作时，需要把车上电缆绞盘的充电枪及电缆放出拖至电动汽车用户端，再插上充电枪。目前一般是采用人力的方式拖出和缠绕回收电缆，费工又费时，电缆反复扭曲也容易加速老化失效；尤其是对于直流充电用电缆，由于电缆直径大，笨重，操作更为困难和麻烦，电缆在地面上拖动也容易产生磨损、扭曲和损坏。Charging a car with a charging car is different from the location of the charging station using the charging post and is not fixed. Often due to road and parking conditions and the location of the charging sockets of various types of electric vehicles, the charging cable length is much higher than that of the fixed charging pile, which generally requires 10 to 15 meters. It is necessary to provide a cable winch on the charging car. When the charging car is working, it is necessary to drag the charging gun and cable of the cable winch on the car to the user end of the electric car, and then insert the charging gun. At present, it is generally carried out by manpower to pull out and wrap the recovered cable, which is laborious and time consuming, and the cable is repeatedly twisted and easily accelerated the aging failure; especially for the DC charging cable, because the cable diameter is large, bulky, and the operation is more difficult and troublesome, Cables that are dragged on the ground are also prone to wear, distortion, and damage.
通常应急救援充电车会根据市场需要配备多种充电电缆和充电 枪以适应不同类型的需求，由于不同电缆差异较大，芯线种类较多，导致电缆卷盘结构尺寸差异较大，卷盘并列布置时轴向尺寸较大，导致占车厢空间较大。而且并列布置集电器盖打开不便，维修困难。此外电缆卷盘中电缆一般裸露在外，行驶中容易受扬尘的污染。且操作时存在一定安全风险。Usually the emergency rescue charging car will be equipped with a variety of charging cables and charging according to market needs. The gun adapts to different types of requirements. Due to the large difference between different cables and the variety of core wires, the cable reel structure size is quite different. The axial size of the reels is arranged in parallel, resulting in a large space for the car. Moreover, it is inconvenient to arrange the collector cover in parallel, and maintenance is difficult. In addition, the cable in the cable reel is generally exposed, and it is easily contaminated by dust during driving. There are certain security risks when operating.
