An embodiment front vehicle body structure of a vehicle body is provided. The vehicle body includes an under body and an upper body coupled to the under body, and the front vehicle body structure includes side sills respectively disposed at two opposite sides of the upper body based on a vehicle width direction and wheel arch members respectively connected directly to front ends of the side sills in a forward/rearward direction of the vehicle body and coupled to a front part of the under body.

An embodiment joint structure for a vehicle body is provided. The vehicle body includes an underbody and an upper body coupled to the underbody, and the joint structure includes a front bulkhead coupled to an inside of each side sill of a pair of side sills provided on both sides of the upper body, respectively, a rear bulkhead coupled to the inside of each side sill of the pair of side sills on a rear side of the front bulkhead, and a support bracket coupled to the front bulkhead and the rear bulkhead along a length direction of the vehicle body.

The vehicle with right and left front seats, a cargo bed located behind the right and left front seats, a guide rail located on the cargo bed, and a rear seat with a seat frame connected to the guide rail and slidable in the front-rear direction along the guide rail. This structure enables the cargo bed to have a sufficient capacity while preventing the vehicle body from increasing in size, and secures freedom in the shape of the rear seat.

A chassis frame for an electric vehicle may include: a first frame and a second frame spaced apart from each other in a longitudinal direction of the electric vehicle; a center frame disposed between the first frame and the second frame, and configured to have side members spaced apart from each other in a widthwise direction of the electric vehicle; a first fastener which extends from the first frame, and is fastened to a first side of the side member; and a second fastener which extends from the second frame, and is fastened to a second side of the side member, wherein the first fastener and the second fastener are configured to be in contact with entire peripheries of the side member.

A plurality of metallic bulkheads fixed at predetermined intervals inside a side sill includes a partition wall portion partitioning an inner space of the side sill and a bonding flange portion formed to surround an outer periphery of the partition wall portion and bonded to an inner surface of the side sill and has an I-shaped cross-section. The partition wall portion of one bulkhead fixed to an upper curved portion is disposed to be substantially parallel to a radial direction passing through a curved center of the upper curved portion such that the partition wall portion is propped to prevent the upper curved portion from being crushed when a collision load in a front and rear direction is input to a pillar portion of the side sill to prevent the collapse deformation of the pillar portion.

A fastener assembly for a motor vehicle is provided. The fastener assembly comprises a fastener configured to couple a first component to a second component of the motor vehicle, the fastener comprising a shank configured to be received within a bore of the first component; and a retaining member, the retaining member being couplable to the fastener and the first component, the retaining member comprising an opening configured to receive the fastener shank and to provide a resistance against the removal of the fastener shank from the bore of the first component, wherein the retaining member comprises a deformable portion configured to deform from a first state to a second state by virtue of the operating environment of the first component such that the fastener may be removed from the bore when the deformable portion is in the second state following operation of the motor vehicle.

A joint for a motor vehicle body comprises a first structural member fabricated from aluminum attached to a second structural member fabricated from steel. The second structural member has an adjoining portion that is in substantially juxtaposed abutting relation with the first structural member when the second structural member is attached to the first structural member. The second structural member has a ramp portion terminating in a bare exposed edge on the second structural member and upon which the bare exposed edge is disposed. The bare exposed edge is displaced from the first structural member to form a gap between the first structural member and the bare exposed edge to prevent corrosion of the bare exposed edge without the use of adhesives and sealants.

A screw tool system for use with vehicle covers includes a vehicle screw adapter which interfaces with the receiver end of the screw and uses a standard cordless power screwdriver to drive the screw either into or out of the frame and vehicle top. A standard screwdriver handle could be used in place of the cordless power screwdriver. The cordless power screwdriver is preferred over a corded power screwdriver due to ease of use and lower power, which reduces the threat of stripping the screw.
