[0002] In the field of automatic guided vehicles (AGVs), charging is one of the key requirements to keep the vehicle running normally. At present, there are some charging devices for charging AGVs, but there are some problems with existing charging devices in practical applications. First, the manual charging method requires manual intervention, which is not only inefficient but also easily affected by human factors. Secondly, although the battery replacement charging method can achieve fast charging, it requires additional manpower and equipment costs and cannot meet real-time charging needs. In addition, the existing automatic charging devices usually use fixed charging input and output terminals, which have high requirements for the positioning accuracy of AGVs, and the charging operation in a small space is limited. Therefore, a new automatic guided vehicle charging device is needed to improve the charging efficiency, convenience and applicability, and meet the charging needs of AGVs in actual work.
