In an automobile inner panel and an automobile panel that includes the automobile inner panel, panel rigidity of the panel is secured while achieving a weight reduction. An automobile inner panel 2 has a plurality of sub-units 10 that each include a flange 11, an inclined wall 12 continuous with the flange 11, and a bottom portion 13 continuous with inclined wall 12 and separated from the flange 11. The bottom portions 13 and 13 of the sub-units 10 and 10 which are adjacent to each other are butted against each other and are directly continuous with each other. A maximum value of a distance D1 between two of the flanges 11 and 11 of two of the sub-units 10 and 10 in which the bottom portions 13 are arranged separated from each other and which are adjacent to each other is 250 mm or less.

A subframe assembly for a vehicle, including: a straight arm; and a side bracket including a base coupled to an outboard side of the straight arm; wherein the outboard side of the straight arm defines a recess; and wherein an inboard side of the base of the side bracket includes a protrusion that nests conformally within the recess defined by the outboard side of the straight arm. Top and bottom edges of the outboard side of the straight arm, the recess, the inboard side of the base of the side bracket, and the protrusion are chamfered. The chamfered portions of the top and bottom edges of the outboard side of the straight arm, the recess, the inboard side of the base of the side bracket, and the protrusion are welded to join the side bracket to the outboard side of the straight arm.

An embodiment vehicle body connection structure for connecting an underbody on which a battery assembly is mounted and an upper body includes a plurality of main mounting portions engaging the battery assembly, a chassis frame on both sides of the underbody and side sills on both sides of the upper body along a length direction of the upper body through a main engage unit.

A modular vehicle system includes a cabin module, front end module, and rear end module. The cabin module includes a floor structure of the vehicle and has a front end and a rear end, and a plurality of panels extending upwardly from the floor structure. The front end module is configured to include the front wheels of the vehicle. The rear end module is configured to include rear wheels of the vehicle. The front end module is configured to securely attach to the front end of the cabin module, and the rear end module is configured to securely attach to the rear end of the cabin module. Various types of modules can be constructed and assembled to define various types of vehicles. The floor structure of the cabin module may include an electric vehicle battery, and different cabin modules may have different battery types enabling different vehicle ranges.

A structural assembly for a pickup truck sidewall includes, among other things, a C-pillar, a belt rail extending rearward from the C-pillar, and a truss spanning from the belt rail to the C-pillar. A method of structurally supporting a sidewall of a pickup truck includes the steps of securing a first end portion of a truss to a belt rail that extends rearward from a C-pillar of the pickup truck, and securing an opposite, second end portion of the truss to a C-pillar.

A vehicle floor panel is provided in which a honeycomb core made of metal sandwiched and adhered between two CFRP plates is one in which a large number of core units formed into a polygon shape are continuous within one plane so as to share a side of the polygon. Since closed-section parts formed by a hat-shaped cross section part formed along the side and one CFRP plate are continuous with each other at a vertex of the polygon of the adjacent core units, not only is it possible to lighten the weight by opening the interior of the polygon (P) shape core unit, but it is also possible to enhance the energy-absorbing performance by dispersing and transmitting a collision load inputted into one direction of the floor panel toward a plurality of other directions because the high strength load transmission path is continuous with other load transmission paths.

The proposed connection device includes attachment portions that are separated from each other such that the one of the crash absorbing member and the vehicle body component is insertable between the attachment portions. This allows for a transverse slidable motion of the one of the crash absorbing member and the vehicle body component with respect to the main body. Thus, the crash absorbing member or the vehicle body component, whichever is going to be attached to the attachment portions, is slidable in transverse direction, i.e. substantially perpendicular to a longitudinal direction of e.g. the crash absorbing member.

A chassis frame module for an electric vehicle may include: a main frame; a front frame connected to the front of the main frame; and a rear frame connected to the rear of the main frame. The front frame may include: a first front frame disposed at the front of the main frame; a second front frame extending from the first front frame toward the main frame; and a front joint part configured to connect the main frame and the second front frame.

The disclosure relates to a rear roof cross beam mounting structure for a vehicle, and a vehicle. The rear roof cross beam mounting structure comprises: a left D pillar and a right D pillar, the left D pillar and the right D pillar each being fixed to a body of the vehicle; a lower cross beam, the lower cross beam being arranged between the left D pillar and the right D pillar; and a pre-positioning structure, the pre-positioning structure comprising pre-positioning posts and pre-positioning holes, wherein the pre-positioning posts are columnar protrusions respectively extend upwardly from bodies of the left D pillar and the right D pillar along a center line offset from a Z-direction of the vehicle by a predetermined acute angle, the pre-positioning holes are U-shaped grooves respectively formed in a left side edge and a right side edge of the lower cross beam and having openings facing away from a body of the lower cross beam, and the columnar protrusions are configured to be insertable into corresponding U-shaped grooves such that the lower cross beam can be placed on each of the left D pillar and the right D pillar along the center line. The vehicle of the disclosure can efficiently achieve pre-positioning fit, the assembly takt can be optimized, and the assembly efficiency can be increased.

A vehicle structural support is disclosed having first and second metallic members. A first metallic member has first and second sides, where the second side has a reduced thickness section. A second metallic member is coupled to a first side of the first metallic member. A third member is coupled to the first metallic member and positioned in the reduced thickness section. The second metallic member extends beyond the reduced thickness section to at least partially overlap the third member. The third member may be a fender for a vehicle.
