Background
In recent years, electrically driven vehicles have gained increasing numbers of applications in industry and life, and in particular, in certain industrial applications, many charging processes have been disengaged from manual operation. For example, with the rapid development of intelligence and automation, the advent of AGVs (automated Guided vehicles) has largely solved various problems faced by manual operations in conventional industrial applications. An AGV cart is generally a transport vehicle equipped with an electromagnetic or optical automatic guide device, capable of traveling along a predetermined guide path, and having safety protection and various transfer functions. When the electric quantity is insufficient and charging is needed, the AGV trolley can be automatically positioned and guided to a charging pile (generally fixed to the ground or the wall of a work place) matched with the AGV trolley for charging. Generally speaking, the charging of the AGV dolly is realized by inserting a charging head on the charging pile into a charging port on the AGV dolly. Because the automatic alignment of the charging head and the charging port always has certain deviation, the charging head cannot be inserted into the charging port and the charging fails; more seriously, it is likely to cause damage to the charging head or the charging port. Existing charging heads are often equipped with a float mechanism to adjust their position during alignment with the charging port to reduce or counteract the misalignment to effect charging. However, the above technical problems are still difficult to completely solve by this structure. Therefore, how to overcome the alignment deviation between the charging head and the charging port, and further to achieve efficient automatic charging, and reduce the damage to the charging accessories is still an important issue to be solved urgently.
