The invention discloses a manufacturing method of an automobile mark display key cover. The method comprises the following steps: manufacturing a key top with a material of a first color, placing a coverage structure on a coverage area of the key top, spraying a graphic layer of a second color on an open area, removing the coverage structure, spraying the graphic layer of a third color on the surface of the key cover, then, etching the coverage area to expose the first color, and exposing the second color at the open area; by the technical mode above, indication effects of two different colorscan be presented under the action of lamp light on the key cover, by the material of the first color and the graphic layer of the second color sprayed on the key cover, the first color is exposed atthe coverage area of the key cover, the second color is exposed at the open area, thus, the key cover capable of displaying two colors under the action of an indication lamp can be obtained, techniqueis simple and convenient to operate, processing efficiency is improved greatly, and cost is reduced.
Description
technical field [0001] The invention relates to the technical field of automobile keys, in particular to a method for manufacturing an automobile mark display light-transmitting key cover. Background technique [0002] There are various keys in the car. In order to facilitate the driver to quickly distinguish the keys, the key cover of the key will be provided with different shapes of marks with light transmission function. In a dark environment, the light inside the key can pass through the key. The markings on the lid show through. [0003] Chinese patent document CN203617185U discloses a light-transmitting mark display button for automotive interiors, including a light-transmitting button shell pressed from a light-transmitting substrate and a light-shielding coating, and the light-shielding coating is evenly coated on the exposed surface of the light-transmitting button shell , engraving a marking pattern groove of a predetermined shape on the light-shielding coating by...
