Description

A special combined cable reel for electric vehicle emergency rescue charging vehicle

technical field

The utility model relates to a cable reel, in particular to a special combined cable reel for emergency rescue and charging vehicles of electric vehicles.

Background technique

In the past ten years, the total number of domestic automobiles has grown rapidly, and the demand for fuel has also increased rapidly. Automobile fuels are mainly petrochemical energy such as diesel, gasoline or natural gas. However, my country's domestic petrochemical energy sources mainly rely on imports, and the supply of petrochemical energy is becoming increasingly tight. 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 is gradually accelerating. The total number of hybrid and pure electric vehicles is growing rapidly, and the demand for emergency rescue services for electric vehicles is gradually emerging. There is an urgent need for electric vehicle emergency rescue vehicles with professional functions to meet the growing market demand. At the same time, there is also an urgent need for charging guns and cable retractable devices as supporting equipment for charging power output equipment.

Using a charging car to charge an electric vehicle is different from using a charging pile to charge the equipment in a different location and not fixed. Often due to road and parking lot conditions and the different locations of charging sockets for various types of electric vehicles, the length of the charging cable is much longer than that of the fixed charging pile charging method, generally requiring 10 to 15 meters. It is necessary to set a cable winch on the charging car like this. When the charging car is working, it is necessary to release and drag the charging gun and cable of the cable winch on the car to the electric vehicle user terminal, and then plug in the charging gun. At present, it is generally used to pull out and wind the recovery cable manually, which is labor-intensive and time-consuming, and the repeated twisting of the cable is easy to accelerate aging and failure; especially for the cable for DC charging, due to the large diameter and bulkiness of the cable, the operation is more difficult and cumbersome. Cables are also prone to abrasion, twisting and damage as they drag across the ground.

Usually emergency rescue charging vehicles will be equipped with a variety of charging cables and charging guns according to market needs to meet different types of needs. Due to the large differences between different cables and many types of core wires, the structure and size of the cable reels vary greatly, and the reels are juxtaposed. When arranged, the axial dimension is relatively large, resulting in a large space in the compartment. Moreover, it is inconvenient to open the collector cover arranged side by side, and it is difficult to maintain. In addition, the cables in the cable reel are generally exposed, and are easily polluted by flying dust during driving. And there are certain security risks in operation.
