KR-20260063986-A - MANUFACTURING DEVICE FOR AMBIENT LIGHTING DIFFUSER FOR ELECTRIC VEHICLE STEERING WHEEL

Abstract

The present invention relates to a manufacturing apparatus for an ambient lighting diffuser for an electric vehicle steering wheel, comprising: a top mold having a top cavity corresponding to the housing of the diffuser; a bottom mold having a bottom cavity corresponding to the plate of the diffuser; an injection port for a transparent synthetic resin formed in the top mold and connected to the top cavity of the top mold; and a suction unit for removing bubbles connected to the top cavity of the top mold or the bottom cavity of the bottom mold; thereby enabling the suction unit to remove bubbles that may occur during the synthetic resin injection process so that no unnecessary air bubbles remain inside the diffuser during molding, and thereby increasing the transparency of the diffuser and improving its optical quality.

Description

Manufacturing device for ambient lighting diffuser for electric vehicle steering wheel The present invention relates to a manufacturing apparatus for an ambient lighting diffuser for an electric vehicle steering wheel, which is designed to manufacture a diffuser for diffusing and transmitting light emitted from an ambient lighting module mounted on the steering wheel to the driver. In particular, the invention enables the manufacture of a high-quality diffuser by injecting a transparent synthetic resin into a mold to remove air bubbles within the cavity during diffuser molding. The steering wheel of an electric vehicle is equipped with an ambient lighting module that indicates the ignition is ON, and a diffuser is installed to protect the ambient lighting module from the outside while diffusing the light emitted from the module. Technologies regarding lighting such as ambient lighting modules installed in such vehicles, or auxiliary components such as diffusers for this purpose, include: Korean Patent Registration No. 10-2207465 (registered on January 20, 2021, hereinafter referred to as 'Document 1') “Method for Manufacturing Plastic Vehicle Additive Parts” is disclosed, Literature 1 describes a method for manufacturing a plastic vehicle accessory having a decorative element, wherein a first polymer material is provided, a decorative element is transferred from a carrier film to a first surface of the first polymer material by hot stamping with a punch, a second polymer material is applied to the first surface of the first polymer material, and accordingly, the decorative element is arranged between the first polymer material and the second polymer material, and at least the first polymer material or the second polymer material is transparent. As another technology, Korean Patent Publication No. 10-2024-0111057 (registered July 16, 2024, hereinafter referred to as 'Document 2') “Lighting device for a vehicle and method for manufacturing the same” is disclosed, Literature 2 relates to a vehicle lighting device and a method for manufacturing the same, comprising: a light source unit that emits light; a light guide plate that diffuses the light emitted from the light source unit; and a lens cover that transmits the light diffused through the light guide plate and emits it forward, wherein irregularities are formed on the inner surface of the lens cover into which the light passing through the light guide plate is incident, such that the thickness varies according to the position and area on the lens cover, thereby providing a lighting function that can give a unique and beautiful exterior image and aesthetic sense to an electric vehicle.
