Description

Charging door equipped with a projection lamp and method of controlling projection of the same The present invention relates to the field of vehicle electronic control technology, and in particular to a charging door equipped with a projection lamp and a method for controlling the projection thereof. Currently, the charging door of an electric vehicle mainly includes a charging door base and a charging door panel hinged to the charging door base, and the charging door base is equipped with a charging port for inserting a charging gun. When charging an electric vehicle using a charging gun, information regarding the charging amount of the electric vehicle is not displayed on the charging door base, so the vehicle user cannot intuitively determine whether the electric vehicle is currently being charged normally, or the amount and status of the battery power during charging. Furthermore, while some vehicles are equipped with charging indicator lights, they are typically installed within the base of the charging door. For example, the indicator light is mounted around the charging port and utilizes a slender, elongated semicircular light guide. These indicator lights have some drawbacks. First, the light occupies a significant amount of space within the vehicle's limited area, making component placement difficult. Second, the battery level is not easily visible from a distance unless the user is standing directly in front of the charging door, making it difficult to determine the current charge. Additionally, at night or in dimly lit conditions, the lack of a bright light illuminating the ground beneath the charging door can obstruct visibility. Consequently, this often causes inconvenience to the user during charging, as the charging gun may collide with the base of the door while being inserted or the user may bump into the charging door panel during the process. Moreover, charging doors equipped with indicator lights only provide power level display or fault notification functions and lack features for user interaction. Consequently, such charging doors lack a sense of luxury. Therefore, a charging door structure equipped with a multi-functional projection lamp, such as a lighting function, an indicator function, and a customer-interactive welcome lighting function, is required. The description of the background technology above is intended merely to facilitate a deep understanding of the technical methods of the present invention (technical means used, technical problems to be solved, technical effects occurring, etc.), and should not be construed as an acknowledgment or implied in any form that such information constitutes prior art known to a person skilled in the art.
