Description

Electric vehicle charging socket adapter pile

Technical field

The present invention relates to the field of electric vehicles, and in particular, to an electric vehicle charging socket adapter pile.

Background technique

At present, electric vehicles are gradually entering daily life. During the use of electric vehicles, when the electric vehicle's power is insufficient, it needs to be charged through a charging pile. Currently fixed charging piles are usually used. When using a fixed charging pile, after charging is completed, if the charging gun is not removed in time and the fully charged electric vehicle is driven out of the charging parking space, other electric vehicles that are ready to be charged will not be able to use the charging pile; on the other hand, if the charging pile is fixed All charging piles are in use. Electric car owners who are ready to charge must wait until the charging electric car has finished charging and leaves the charging parking space, and then drives their own electric car into the charging parking space before they can start charging. In this way, electric car owners must spend a lot of time before, after and during charging, and the experience is very poor. To address this problem, there is a mobile charging pile solution developed with patented technology. After the mobile charging pile completes charging one electric vehicle, it moves to another parking space to charge another electric vehicle. This reduces the number of charges during the charging process of the electric vehicle. The participation of electric car owners improves their experience of charging electric cars.

When charging through mobile charging piles, due to different brands of electric vehicles and different parking positions, the position and angle of the charging socket of the electric vehicle relative to the ground are different. As a result, the charging gun on the mobile charging pile cannot be well adapted to different brands and For electric vehicles in different parking positions, existing mobile charging piles generally solve this problem by setting up high-precision 3D visual recognition and a six-axis robotic arm structure, which greatly increases the cost.

The patent document with the publication number CN112406602A discloses a movable electric vehicle charging pile for new energy electric vehicles, which includes a base and a charging pile body. The charging pile body is fixed on the base. The base is located on the left and right sides of the charging pile body respectively.

Each N-shaped frame is also provided with a driving mechanism for driving the slide bar between the vertical frames on both sides of the N-shaped frame to slide up and down. , there are also protective rods located on the front and rear sides of the charging pile body between the two n-shaped frames. However, this patent document still has the defect that it cannot be well applied to the different spatial positions and angles of the charging sockets of electric vehicles of different brands and different parking positions.
