Method and system for automatically opening and closing charging cover of transportation tool, charging gun and transportation tool

Abstract

The invention relates to a method and system for automatically opening and closing a charging cover of a transportation tool, a charging gun and the transportation tool. The method comprises the following steps: carrying out near-field communication between the transportation tool and the charging gun, wherein the transportation tool and the charging gun are separately provided with a first moduleand a second module which are used for near-field communication; acquiring a near-field communication signal between the first module and the second module; judging whether at least one part of the charging gun has been currently located in a first area or outside a second area according to the acquired near-field communication signal, wherein the first area and the second area are respectively defined as an area which is distant from the preset position on the transportation tool by a preset first distance and an area which is distant from the preset position on the transportation tool by apreset second distance, and the first distance and the second distance are equal or unequal; executing the following operations according to the judgment result: if the charging gun is determined to be located in the first area, controlling a charging cover to be in an open state for exposing a charging port; or if the charging gun is determined to be located outside the second area, controlling the charging cover to be in a closed state to close the charging port.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a method for automatically opening and closing a charging cover of a transportation tool, an automatic opening and closing system for a charging cover of a transportation tool, a charging gun and a transportation tool. Background technique [0002] At present, various means of transportation using electric energy as power have been widely used, and these means of transportation need to continuously supplement electric energy during use. For example, for a pure electric vehicle, people generally use a charging gun, align it and insert it into the charging port of the vehicle to supplement electric energy. When charging, people usually need to manually open the charging cover first, so that the charging port is exposed to the charging gun to implement the charging operation, and after the charging is completed, people also need to manually close the charging cover to protect the c...

AI Technical Summary

Problems solved by technology

The above manual operations are not only inconvenient, but also cumbersome, and affect the user's good experience in charging operations, vehicle use, etc.

[0003] In addition, although the prior art has provided some technical means to try to improve, for example, the wireless signal can be triggered by artificially actively pressing the button on the head of the charging gun, so as to control the opening or closing of the charging cover, but these Existing technical means still have deficiencies in many aspects such as intelligence, humanization, convenience, control accuracy and reliability, user experience, etc., and can be further improved and optimized
