Abstract: An external lighting apparatus delivers various messages through selective lighting by applying a lighting function to the exterior of a vehicle. The apparatus includes a light source module with a plurality of light sources and a light guide in which light emitted from the light sources is incident. The light guide reflects the incident light so that the light travels in different areas. The apparatus has a light cover composed of a plurality of transmission parts into which the light, travelling in different areas via the light guide, is incident. The light is emitted to different lighting areas through each transmission part to create a plurality of illumination images.

Abstract: The present disclosure discloses a bumper beam for a motor vehicle including a center portion free of mobility-specificity and side portions that may be altered according to design and specification of the mobility to secure collision performance so that the bumper back beam of which collision performance is secured and which satisfies various mobilities may be flexibly applied. Accordingly, it is possible to configure the back beam satisfying various mobilities based on a standardized model to secure collision performance so that manufacturing cost is reduced by assembling and producing the back beams with minimum molds.

Abstract: The present disclosure provides a thermoplastic resin composition having high rigidity and a low coefficient of linear thermal expansion and a molded article including the same. The thermoplastic resin composition includes a first propylene-ethylene copolymer, a second propylene-ethylene copolymer, a thermoplastic elastomer, an inorganic filler, and a sodium-phosphate-based nucleating agent as appropriate, and thus a molded article produced therefrom can exhibit improved mechanical rigidity, impact resistance, and dimensional stability. Even when formed to a low thickness for weight reduction, the molded article can be imparted with excellent processability, high tensile strength, a high flexural modulus, and high impact strength.

Abstract: A vehicle radiator grill that is manufactured by integrally combining plastic resins of different colors by using double injection and thus has two different colors is provided. The vehicle radiator grill includes a base component that has a first color and forms an exterior of a radiator grill while providing a vent component which has a plurality of air passages formed therethrough and blocked parts are disposed at both sides of the vent component. Additionally, an image component which has a second color different from the color of the base component is integrally formed with the base component by using double injection and exposes the second color toward the front of the radiator grill through the air passage to form an image of two different colors.

Abstract: Disclosed is a variable spoiler apparatus of the rear bumper for vehicles. The variable spoiler apparatus includes a linkage device, installed on a bumper back beam, and varies in length in an up-down direction during a rotation. A spoiler is coupled to the linkage device and is able to move in the up-down direction by the rotation of the linkage device. A first drive device is installed on the bumper back beam. The first drive device is provided with a first rotating shaft coupled to the linkage device to transmit rotating force. A guide is rotatably installed on the bumper back beam and is able to extend in the up-down direction. A second drive device is coupled to the guide so as to be movable in the up-down direction. When the second drive device is operated, the spoiler is tilted by a length variation operation of the length-variable unit.
