An embodiment is a roof reinforcement structure of a vehicle body, the roof reinforcement structure including a side complete assembly disposed on both sides of a vehicle body respectively, a front roof rail assembly connecting the front of the side complete assemblies, a rear roof rail assembly connecting the rear of the side complete assemblies, and at least two spines disposed side by side to connect the front roof rail assembly and the rear roof rail assembly.

Roof reinforcement structure of vehicle body

An embodiment connection structure of tubular type pillars includes an outer joint bracket coupled to a sill outer member of a side sill, wherein a lower portion of a pillar member is fitted and coupled to the outer joint bracket along a vehicle width direction, and an inner joint bracket coupled to a sill inner member and coupled to the outer joint bracket, wherein the sill inner member and the sill outer member are joined to each other.

Connection structure of tubular type pillars

A fiber-reinforced vehicle body structure includes a first frame made of fiber-reinforced plastic or carbon fiber-reinforced plastic and having multiple sections, and a second frame that continuously extends from any one of the multiple sections of the first frame.

Fiber-reinforced plastic vehicle body structure and manufacturing method thereof

A method of assembling a sub-frame of a vehicle with the front side member of the vehicle includes integrally forming a supporting end of a mounting nut that protrudes in a radial direction in a center of an external circumference of the mounting nut, forming a through hole in a lower surface of the front side member, forming a seat as a groove in an internal surface of the through hole, inserting a lower end of the mounting nut into the through hole so that the supporting end is supported by a circumference of the through hole, settling a head of the mounting nut in the seat, and welding the supporting end and the head along the circumference of the through hole and a side of the seat to assemble the sub-frame to the front side member.

Method of assembling sub-frame and front side end in vehicle

A rear vehicle body reinforcing structure may include a rear reinforcing member deployed on a periphery of a vehicle body rear door opening and configured to be coupled to a rear vehicle body, in which the rear reinforcing member is opened upward in a height direction of a vehicle.

Rear vehicle body reinforcing structure

A composite vehicle body panel includes a fiber reinforced plastic panel and a steel flange disposed in the fiber reinforced plastic panel and having an edge protruding outward from the fiber reinforced plastic panel beyond an outer edge of the fiber reinforced plastic panel. The composite vehicle body panel can be used in vehicle structures manufactured on standard vehicle productions lines, thereby easing vehicle manufacturing, improving productivity, and providing increased rigidity to the vehicle bodies. A method of manufacturing the composite vehicle body panel and a vehicle structure using the panel are also provided.

Composite vehicle body and manufacturing method thereof and vehicle body structure using the same

A vehicle body includes: rear side members disposed at both sides of the vehicle body; a rear cross member rear having both end portions fixed to the rear side members; a rear cross member front having both end portions fixed to the rear side members, and disposed in front of the rear cross member rear; and a rear cross panel having a lower surface that is supported on and joined to the rear side members, the rear cross member rear, and the rear cross member front.

Vehicle body having rear side member

A rear shock absorber mounting structure for a vehicle includes a rear shock absorber upper cover which may be mounted on a wheel housing and on which a rear shock absorber may be engaged and supported, an inner dual rail member which may be mounted on an inner surface of the wheel housing, which may be oriented toward a vehicle interior along a width direction of a vehicle, and an outer dual rail member which may be mounted on an outer surface of the wheel housing, which may be oriented toward an outside of the vehicle interior along the width direction of the vehicle, and thereby, the rear shock absorber mounting structure may be configured by a simple structure, and mounting stiffness of the rear shock absorber may be increased.

Rear shock absorber mounting structure for vehicle

A roof side rail is connected to a roof panel and includes a multi-sectional rail having a plurality of integrally formed ribs and bent along a shape of an upper portion of a side surface of a vehicle body, and a reinforcement rail that is combined with an inner side surface of the rail, an upper side flange is connected to the roof panel, and a lower side flange is engaged with a weather strip.

Roof side rail

A mounting unit for a sub-frame of a vehicle is provided. The mounting unit is used for engaging a front side member with the vehicle's sub-frame. The mounting unit includes a welding seat that is formed as a groove on a lower side of the front side member. The mounting unit further includes a mounting nut assembled with the front side member, a welding flange integrated with an external circumference and a head of the mounting nut and inserted into the welding seat to be combined with the welding seat, and a member seat that is formed outside the welding flange and with which a fender upper connecting member is combined.
