The present invention discloses a knob cap for a high-pressure tank including a first knob cap portion having a coupling groove coupled to a knob of a liner of the high-pressure tank in a lower surface, including a peripheral wing portion extending outward to be in contact with a surface of the liner to outside of a lower portion, and having a column portion in the shape of a column extending upward in a center; and a second knob cap portion integrally coupled with the first knob cap portion, having the column portion of the first knob cap portion inserted into a hollow, and including a plurality of inner grooves in the shape of a column having an upper end opened outside of the hollow and extending downward.

Knob cap for high-pressure tank

The present invention relates to a knob cap for a high-pressure tank including a coupling groove portion corresponding to a knob of a liner of the high-pressure tank formed in a lower surface of a body; a peripheral wing portion extending outward in a lower end of an outer circumferential surface of the body to be in contact with a surface of the liner; and a thickness conversion portion formed in the outer circumferential surface of the body to change a thickness between a center line and the outer circumferential surface.

Disclosed are a pressure vessel boss and a pressure vessel having same, the boss comprising: a boss body in which a through hole configured to connect an interior to an exterior of the pressure vessel is formed; and a boss joint portion which surrounds an outer surface of the boss body, radially extends outward, and has an outer surface coming into surface contact with and joined to an opening surface of a liner, wherein the outer surface has a cross-sectional shape having three or more line segments connecting a top to a bottom of the boss joint portion and including at least one convex corner and at least one concave corner.

Pressure vessel boss and pressure vessel having same

The present invention relates to an impact beam having a structure in which a plurality of peak portions and a plurality of valley portions are repeatedly and alternately disposed, and including a reinforcement fiber that is continuously coupled to at least one of the plurality of peak portions and the plurality of valley portions along a length direction.

Impact beam

A bumper beam for a vehicle is attached to a front or rear portion of the vehicle, includes a beam main body having a front surface opposite to a surface to be attached to the vehicle, the front surface being curved outwardly, and the beam main body having a C-shaped section opened outwardly toward the front surface, and stay portions formed on both sides of the beam main body, each of the stay portions having an opening at a rear surface thereof. The beam main body includes a fiber reinforced plastic.

Bumper beam for a vehicle

A bumper beam assembly system includes a bumper beam and a stay connecting the bumper beam to a vehicle, wherein the stay is replaceably coupled to both sides of the bumper beam to occupy a corner portion of the bumper beam. The bucket structure includes a frame assembly part that is coupled to a frame, a first sidewall disposed on one side of the frame assembly part to constitute the corner portion of the bumper beam, a second sidewall disposed on the other side of the frame, and a bumper beam assembly part extending from the frame assembly part, the first sidewall, and the second sidewall in a flange shape and coupled to the bumper beam.

Bumper beam assembly system

The present invention relates to a hybrid seat frame for a vehicle and provides a hybrid seat frame for a vehicle including a main frame formed of glass fiber and a reinforced frame formed of carbon fiber to secure stiffness in a direction perpendicular to the longitudinal direction and torsional stiffness and to reduce its weight, thereby improving fuel efficiency of the vehicle.
