摘要： 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.

摘要： A method of manufacturing a bumper back beam for vehicles is provided. The method includes shaping a planar strip using a pressing process and a planar surface component are formed within a central portion of the strip in a longitudinal direction thereof, and recessed components are formed on opposite sides of the planar surface part, and a first flange is formed on an exterior edge of each recessed component. Further, each of the recessed components are bent vertically around a bending boundary line formed between the planar surface component and the corresponding recessed component and the opposite first flanges contact the planar surface component. Additionally, the edges of the opposite first flanges are welded to the planar surface component and the back beam has a pair of closed section components defined by the planar surface component and the recessed components.

摘要： 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.

摘要： Disclosed is a variable spoiler apparatus of the rear bumper for vehicles. The variable spoiler apparatus includes a linkage device, to be installed on a bumper back beam, which is able to vary in length in an up-down direction during a rotating operation. A spoiler is coupled to the linkage device and is able to move in the up-down direction by the rotation operation of the linkage device. A first drive device, to be installed on the bumper back beam, includes a first rotating shaft coupled to the linkage device to transmit a rotating force. When the first drive device is operated, the linkage device is rotated by a rotation of the first rotating shaft so that the spoiler is moved in the up-down direction. A second rotating shaft is rotatably coupled to the linkage device. The second rotating shaft is penetrated and connected to a second drive device.
