A sub-frame mounting combination structure of a vehicle body may include a fender apron side member mounted at the rear end portion of a front side member in the longitudinal direction of the vehicle body, a first side extension disposed in the transverse direction of the vehicle body and connected to the inside of the fender apron side member, a second side extension disposed in the transverse direction and connected to the outside of the fender apron side member, a tunnel member disposed in the transverse direction connecting the first side extensions at both sides at the center portion of the vehicle body to each other, and having the same phase as the first side extension, and a cap type bracket disposed to cover the fender apron side member at a portion where the fender apron side member and the first and second side extensions are connected.

Upper frames and a lower frame that connect a rear end of a coupled body composed of a side sill and a rear pillar and a rear side housing to each other are spaced apart in a vehicle up-down direction. An inclined angle at which a lower frame is inclined to be closer to a vehicle inner side toward a vehicle rear side is larger than inclined angles at which the upper frames are inclined to be closer to the vehicle inner side toward the rear side. A lower joined portion to which a rear end of the lower frame is joined is on a vehicle-width-direction inner side with respect to an upper joined portion in the rear side housing, which is composed of a single member including at least the lower frame rear-end joined portion, and the first and second upper frame rear-end joined portions, and extending therebetween.

An entrance is provided in a side surface of a body of a vehicle. A side portion of the entrance in the width direction is constituted by a first frame member extending in the vehicle up-down direction. A lower end portion of the entrance is constituted by a floor extension portion of a floor member disposed on the inner side of the entrance with respect to the first frame member. The entrance is provided with a joint member. The joint member extends from the floor extension portion of the floor member to the first frame member, and closes a gap provided between the floor member and the first frame member. Thus, it is possible to suppress wind, rain, noise, etc. from entering a vehicle cabin through the gap.

A vehicle body may include a dash crossmember, a rocker extending rearwards from an end of the dash crossmember, a front pillar extends upwards from the rocker along the side portion of the cabin and a reinforcement plate including a first end joined to the dash crossmember and a second end joined to the front pillar. An inner wall of the dash crossmember may have an uneven shape that defines at least one bend extending in the right-left direction. The first end of the reinforcement plate may at least partly have a bent shape that conforms with the uneven shape of the dash crossmember.

An embodiment vehicle body includes a first member extending in a shape having an internal space, the first member having an open side, and a second member coupled to the first member, the second member having an end with a closed surface, wherein the end with the closed surface is received in the internal space of the first member through the open side of the first member, and the closed surface and at least one side wall of the second member are in surface contact with the first member.

An embodiment vehicle front structure includes a pair of front side members, a pair of fender upper members located above the pair of front side members, respectively, a bumper back beam connecting front ends of the pair of front side members, and a front end module connected to the pair of front side members and the pair of fender upper members.

A vehicle undercover structure, includes a vehicle body frame including a first side rail and a second side rail spaced from each other in a width direction of a vehicle; a front undercover mounted on the front of the vehicle body frame; a rear undercover mounted on the rear of the vehicle body frame; and a main undercover disposed between the front undercover and the rear undercover, wherein the main undercover covers a moving component which is movable between an upper limit position and a lower limit position on the vehicle body frame.

An embodiment vehicle body includes a pillar member including an upper fastening portion at an upper end and a lower fastening portion at a lower end, a roof side coupling portion provided in a roof member extending in a longitudinal direction of the vehicle body, wherein the roof side coupling portion is configured to be coupled to the upper fastening portion by insertion coupling, and a side sill side coupling portion provided in a side sill member extending in the longitudinal direction of the vehicle body, wherein the side sill side coupling portion is configured to be coupled to the lower fastening portion by insertion coupling.

A vehicle includes a frame, front and rear wheels, a powertrain comprising an engine and transmission, and various other systems and components. The frame includes various features for supporting components and systems of the vehicle. For example, a rear portion of the frame is configured to support a utility bed, a portion of a cooling system, a portion of an air intake system, and a portion of an exhaust system.

A vehicle body structure includes: a front pillar joined to a dash panel; a front side member extending from the dash panel toward the front of a vehicle; a side sill connected to a bottom end of the front pillar; a rear lower member connecting a rear portion of the front side member and a front portion of the side sill; and a connection member connecting at least two of the front pillar, the side sill, and the rear lower member.
