Abstract: The present invention relates to a frame for an electric vehicle. The frame for an electric vehicle, according to an embodiment of the present invention, having defined therein a battery space in which batteries are located, comprises: a side frame which is located at a part of the periphery of the battery space, includes a first hollow portion having a closed section, and extends in a first direction that is the lengthwise direction of the vehicle; and a reinforcement portion which is located in the first hollow portion and has a surface formed in a second direction that is the width direction of the vehicle.

Abstract: The present invention relates to a battery frame comprising reinforcement members on the front and rear sides of the battery frame, and an electric car frame comprising same. According to an embodiment of the present invention, the battery frame has a battery area defined such that a battery is positioned therein, and comprises: a first subframe; a second subframe; a third subframe connected to one end of the first and second subframes; and a fourth subframe connected to the other end of the first and second subframes. A hollow portion is formed inside the third or fourth subframe, and the battery frame further comprises a reinforcement member disposed in the hollow portion. When seen in a third direction which corresponds to the height direction of the vehicle, the first to fourth subframes are connected as one frame so as to surround the battery area.

Abstract: The present disclosure provides a side sill for a vehicle comprising: a first side sill frame; a second side sill frame coupled to the first side sill frame to form a hollow portion together with the first side sill frame; a first reinforcing frame disposed in the hollow portion and having one side bonded to the first side sill frame to form a first closed cross-section; and a second reinforcing frame disposed in the hollow portion and having one side bonded to the first reinforcing frame to form a second closed cross-section, wherein the first reinforcing frame and the second reinforcing frame include a concavo-convex portion that is continuously formed along the longitudinal direction of the vehicle.

Abstract: A side sill for a vehicle according to one embodiment of the present disclosure comprises: a side sill frame formed to have a hollow portion; a first reinforcing frame disposed in the hollow portion and attached to the side sill; a second reinforcing frame disposed in the hollow portion and attached to the first reinforcing frame and the side sill frame, wherein the first reinforcing frame and the second reinforcing frame are disposed in the hollow portion so as to form a closed cross-section in the hollow portion from a thickness-wise cross-section of the side sill frame.

Abstract: A side sill for a vehicle according to the present invention may comprises: a side sill frame formed to have a cavity portion; a partition member that passes through the cavity portion and partitions the cavity portion into a first cavity and a second cavity; a first reinforcing frame which is positioned in the first cavity and contacts the side sill frame and the partition member to form a closed section in the first cavity on a thickness-direction cross-section of the side sill frame; and a second reinforcing frame which is positioned in the second cavity and contacts the side sill frame and the partition member to form a closed section in the second cavity on a thickness-direction cross-section of the side sill frame.

Abstract: The present invention provides a side sill for vehicles, comprising: a side sill frame having a hollow portion; and a reinforcement frame disposed in the hollow portion and arranged in the longitudinal direction of the side sill frame, wherein: the reinforcement frame includes unit sections which are successive in the longitudinal direction of the side sill frame and have changing heights; and the upper and lower surfaces of the reinforcement frame are spaced apart from the side sill frame.

Abstract: The present disclosure relates to a side sill for a vehicle, wherein the side sill is capable of absorbing an impact during lateral collision of the vehicle to maximally suppress the degree to which the side sill enters the interior, and protecting vehicle occupants and batteries. The side sill for a vehicle comprises: a side sill inner panel; a side sill outer panel coupled to the side sill inner panel; and a first cushioning member disposed between the side sill inner panel and the side sill outer panel and constituting a plurality of closed cross-sections arranged in the width direction of the side sill. The first cushioning member includes a main body formed by bending a single plate, and at least one partition member connecting both surfaces of the main body. A plurality of beads may be formed on the main body and the partition member.

Abstract: Provided are a bonding structure for a flat panel display and a method of forming the same, and a flat panel display, including the bonding structure. The bonding structure of a flat panel display device, which is formed between an upper substrate and a lower substrate to seal and bond the two substrates of the flat panel display device, and the bonding structure includes an outer separation wall and an inner separation wall of same heights being arranged along edges of the upper substrate and the lower substrate with a predetermined interval, and a sealant being applied between the outer separation wall and the inner separation wall.
