Description

Technical Field

[0001] This utility model belongs to the field of charging pile technology, specifically relating to an AC charging device for automobiles. Background Technology

[0002] With increasing global emphasis on environmental protection, reducing vehicle emissions has become a crucial goal in the transportation sector. Electric vehicles, as a zero-emission or low-emission mode of transportation, have received strong support and promotion from governments worldwide. To meet the growing charging needs of electric vehicle users, the research and development of AC charging devices for automobiles has become essential.

[0003] Application CN202320400915.6 discloses a housing for an AC charging pile for automobiles. The housing features a cable harness structure 18 symmetrically arranged on both sides of the main housing 1. The cable harness structure 18 includes a cable tray 181 and a winding post 182. The winding post 182 is located above the cable tray 181, and one end of the winding post 182 is connected to a limiting plate. The main housing 1 has symmetrically arranged adjusting grooves 106 on both sides, which are slidably connected to the winding post 182. The adjusting grooves 106 also have limiting grooves slidably connected to the limiting plate. When the charging cable 3 and charging nozzle 4 are not in use, the charging cable 3 can be wound onto the winding post 182, and the cable tray 181 supports the charging cable 3, preventing it from falling to the ground and causing wear.

[0004] While this structure prevents the charging cable 3 from wearing out when it falls to the ground, the high charging speed and frequent use of chargers necessitate frequent winding of the charging cable. During this winding process, the outer sheath of the charging cable is constantly subjected to friction from the winding post 182. Loose winding makes it difficult to secure, while tight winding results in significant friction at the point of contact with the cylindrical edge of the winding post 182. Over time, this friction causes the outer sheath to gradually thin, eventually leading to wear. The cable typically contains multiple conductors for transmitting power or data. Frequent winding causes these conductors to bend continuously. From a materials mechanics perspective, when a conductor bends, its outer side experiences tensile force, and its inner side experiences compressive force, much like repeatedly bending a metal wire. After multiple windings, the internal metal structure of the conductor will experience fatigue. When this fatigue accumulates to a certain extent, the conductor may break, especially near stress concentration points such as plugs or interfaces, where the probability of breakage is higher. Once a conductor breaks, the charging cable will be unable to transmit power or data normally, leading to charging failure or data transmission interruption. Utility Model Content
