Description

Technical Field

[0001] This utility model relates to the field of vehicle charging technology, specifically to a multi-degree-of-freedom charging pile for electric vehicles based on a spatial adaptive mechanism. Background Technology

[0002] With the advancement of society and technology, electric vehicles have become a key development trend in the future automotive industry and the entire powertrain technology field. Currently, electric vehicle charging equipment in my country is mainly composed of off-board charging devices, which have some significant shortcomings in practical use. Off-board charging devices are mostly fixed in location, making it difficult to flexibly adjust to different parking positions and angles of electric vehicles. This leads to difficulties in docking during charging, requiring drivers to park precisely to complete the charging operation, causing considerable inconvenience to users. Moreover, this fixed-location charging method lacks spatial adaptability; in some special parking scenarios or when vehicles are parked improperly, charging may not be possible, reducing charging efficiency and success rate.

[0003] For example, patent number CN 205544401 U discloses a three-degree-of-freedom automatic charging device for electric vehicles, including three moving platforms, motors controlling the movement of each platform, Hall sensors, a mounting bracket, and a charging interface. Each moving platform includes a base, a vertical moving platform, a horizontal moving platform, and a vertical moving platform, with the movement paths of the three platforms perpendicular to each other. The vertical, horizontal, and vertical moving platforms are interconnected via the base. This device can control the charging device to move flexibly in three directions and precisely dock with the vehicle's charging device.

[0004] For example, patent number CN 215793239 U discloses an automatic charging robot for new energy vehicles, comprising a horizontally placed X-axis servo module, a Y-axis servo module disposed at the drive end of the X-axis servo module and placed perpendicular to the X-axis servo module, a multi-degree-of-freedom robotic arm disposed at the drive end of the Y-axis servo module, and a mounting base disposed at the drive end of the multi-degree-of-freedom robotic arm; the mounting base is respectively provided with an electric gripper, a vision sensor, a laser displacement sensor, and a cover-opening finger; this utility model can be moved to multiple charging piles in different locations, and can not only automatically open or close the charging cover through the cover-opening finger, but also use the electric gripper to grasp the charging gun to charge the car, and the vision sensor can accurately locate the position of the charging cover on the car and the position of the charging port inside the charging cover, and the laser displacement sensor can confirm the insertion depth of the charging gun a second time to ensure that the charging gun and the charging port are in full contact.

[0005] The first patent achieves three degrees of freedom of movement by setting three worm gears in different directions, while the second patent achieves the degree of freedom of control of the charging port by setting a guide rail and a robotic arm. Although both patents can achieve different degrees of freedom of control, neither can charge the car behind the charging station, and there are some issues such as insufficient degrees of freedom. In addition, the charging head of the first patent cannot change its angle, and the vehicle must be directly facing the charging station to charge. Utility Model Content
