Abstract: An electric vehicle structure includes a drive system, a front lateral member and a rear upper lateral member. The front and rear lateral members are elongated in a lateral direction of a vehicle and spaced apart from each other in a forward-rearward direction of the vehicle with the drive system interposed therebetween. The vehicle structure further includes a rear lower lateral member elongated in the lateral direction of the vehicle and disposed beneath a motor of the drive system.

Abstract: An electric vehicle structure includes a chassis frame having a first closed curve that surrounds a battery accommodation space, a watertight panel having another closed curve that surrounds the inside of the closed curve that surrounds the battery accommodation space of the chassis frame, an upper cover coupled to an upper side of the watertight panel and covering an upper side of the battery accommodation space, and an under cover coupled to a lower side of the watertight panel and covering a lower side of the battery accommodation space.

Abstract: A chassis frame of a vehicle includes a deck mounting bracket to mount a deck to an upper side of the deck mounting bracket and coupled to an upper side of a frame side member, a battery cross member installed to be spaced apart from the frame side member by the deck mounting bracket, and side protectors respectively provided at opposite ends of the battery cross member.

Abstract: A tubular type torsion beam is manufactured by bending and welding and coupling a plate material. The plate material has a plurality of protrusions disposed on a plurality of side surfaces in a width direction of the vehicle. The torsion beam is manufactured by molding the plate material in a pipe shape by bending the plate material in the width direction and molding the plate material to dispose the plurality of protrusions to contact each other to form a gap between the plurality of side surfaces of the plate material and then welding and coupling the plurality of side surfaces of the plate material.

Abstract: A differential mounting structure includes a pipe into which a bushing coupled to the differential is forcibly inserted. The pipe is inserted into a through hole of a cross member and is fixedly attached at one end thereof to a flange. Coupling bolts penetrating the flange are connected to nuts welded to the cross member. When the bushing used for installing the differential to the vehicle body is worn down and can no longer do its job, only the bushing mounting assembly is replaced or repaired in the present invention.

Abstract: An anti-lift characteristic of a rear suspension of a vehicle is enhanced by including a carrier at which a rear wheel is rotatably mounted; a trailing arm longitudinally aligned with respect to a vehicle body, ends of the trailing arm being respectively connected to the carrier and the vehicle body; and a connecting unit connecting the vehicle body and a body-side end of the trailing arm, and varying a vertical position of the body-side end according to a running state of the vehicle.
