Description

BACKGROUND OF THE PRESENT INVENTION 1. Field of the Present Invention The present invention relates generally to an indicator light module for a charging port of an electric vehicle. 2. The Prior Arts Electric vehicles are generally provided with a charging port for connecting the charging gun of a charging pile for charging. The charging port is usually equipped with an indicator light, which indicates whether the charging gun is correctly connected to the charging port, whether it is in the charging state, the charging level, whether the charging is completed, etc. by the color or number of the indicator light. In addition, in order to allow users to smoothly connect the charging gun for charging at night or in an environment with insufficient light, some electric vehicles are also equipped with a lighting lamp at the charging port. The conventional indicator light and lighting lamp provided at the charging port of the electric vehicle are two independent products arranged at the charging port, so the structure occupies a large space, the utilization rate of the installation space is low, and more waterproof structures need to be configured, which is costly. SUMMARY OF THE PRESENT INVENTION A primary objective of the present invention is to provide a single module that integrates the indicator light and the lighting lamp used for the charging port of an electric vehicle, that is easier to install, occupies small structural space to achieve high space utilization rate as well as low cost and excellent waterproof effect. The indicator light module for the charging port provided by the present invention comprises: a body, having an inner space disposed with a circuit board positioning groove, an elastic buckle, and a positioning block, with two sides of the body respectively formed with a lamp hole and an opening connected to the inner space; a light source assembly, comprising a light source circuit board and at least one LED arranged on the light source circuit board, and the light source circuit board being arranged inside the inner space with the two opposite sides of the light source circuit board positioned by the elastic buckle and the positioning block, and the LED facing the lamp hole; a control circuit board, disposed in the circuit board positioning groove inside the inner space, and electrically connected to the light source circuit board through a wire; a button cover assembly, having a cover plate and buttons and legs provided on opposite sides of the cover plate, the cover plate covering the opening of the body so that the legs corresponding to conductive carbon particles on the control circuit board; a light-transmitting mask, having a first surface and a second surface connected to each other, the light-transmitting mask covering the lamp hole of the body; and a power line, electrically connected to the control circuit board; wherein, when the power line is energized, the button is subjected to a force so that the legs contact the conductive carbon particles on the control circuit board to form a conductive loop for the LED to emit light, and when the force applied to the button is released so that the legs do not contact the conductive carbon particles, the conductive loop is interrupted and the LED does not emit light. In a preferred embodiment of the present invention, the circuit board positioning groove, the elastic buckle, and the positioning block are all formed integrally with the body. Preferably, a buckle groove can be formed on one side of the light source circuit board, and the buckle groove and the elastic buckle are buckled with each other to fix the light source circuit board. Accordingly, when the light source circuit board is buckled by the elastic buckle, a stable effect is achieved so that the light source circuit board will not move. In a preferred embodiment of the present invention, the area of the first surface of the light-transmitting mask is set to be larger than the area of the second surface. Accordingly, when the light-transmitting mask is set at the charging port of the electric charging vehicle, the first surface of the light-transmitting mask is used as a lighting lamp, and the second surface of the light-transmitting mask is used as an indicator light. In a preferred embodiment of the present invention, the outer periphery of the cover plate and the inner periphery of the opening are sealed using laser welding technology. Accordingly, a simple but excellent waterproof effect is achieved between the button cover assembly and the body. In a preferred embodiment of the present invention, the outer periphery of the light-transmitting mask and the inner periphery of the lamp hole are sealed by laser welding. Accordingly, a simple but excellent waterproof effect is achieved between the light-transmitting mask and the body.
