Description

A charging pile floating contact structure

technical field

The utility model relates to the technical field of charging equipment, in particular to a floating contact structure of a charging pile.

Background technique

In recent years, electric drive vehicles have gradually been widely used in industry and life. In particular, in some industrial applications, many charging processes have been separated from manual operations. For example, with the rapid development of intelligence and automation, the emergence of AGV (Automatic Guided Vehicle, Automatic Guided Vehicle) has greatly solved various problems faced by manual operations in traditional industrial applications. AGV trolley usually refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of traveling along a prescribed guidance path, with safety protection and various transfer functions. When the power is insufficient and needs to be charged, the AGV car can be positioned and guided to the charging pile (usually fixed to the ground or wall of the workplace) for charging. Generally speaking, the charging of the AGV car is realized by inserting the charging head on the charging pile into the charging port on the AGV car. There is always a certain deviation due to the automatic alignment of the charging head and the charging port, which leads to the failure of the charging head because the charging head cannot be inserted into the charging port; more seriously, the charging head or the charging port may be damaged. The existing charging head is often equipped with a floating mechanism to adjust its position with the charging port during the alignment process, so as to reduce or offset the deviation to realize charging. However, this structure is still difficult to completely solve the above-mentioned technical problems. Therefore, how to overcome the misalignment between the charging head and the charging port, so as to achieve efficient automatic charging and reduce damage to the charging accessories, is still an important problem to be solved urgently.
