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 battery housing of a motor vehicle traction battery includes at least one base plate, and two side walls which extend parallel to each other in the longitudinal direction of the motor vehicle and are spaced apart from each other in the transverse direction of the motor vehicle. Formed between the side walls is a number of receiving spaces, within each of which at least one battery module of the traction battery of the motor vehicle is accommodated. A plurality of deformation elements which are spaced apart from one another in the longitudinal direction of the motor vehicle are attached to the inner sides of the side walls. The battery modules are arranged in the receiving spaces in such a manner that, in the region of the deformation elements, lateral deformation spaces are formed between the battery modules and the side walls.

The present invention has as its object the provision of a T-shaped joint structure sufficiently securing a mounting region for another member and securing rigidity of a joint part. A first member and a second member joined with the first member and extending in a direction vertical to the longitudinal direction of the first member are provided. In a side view of first member in the longitudinal direction, the part of the first member joined with the second member, that is, a first member side joining element, is slanted from the first member toward the second member so that the first member becomes tapered. The part of the second member joined with the first member, that is, a second member side joining element, is slanted from the first member toward the second member in the same direction as the first member side joining element. The first member side joining element and second member side joining element are smoothly joined to form a joined part. The joined part is present at least at single side of the first and second member in the lateral direction.

A vehicle body includes: side sills coupled to opposite sides of the vehicle body in a forward-rearward longitudinal direction of the vehicle body, rear lower members coupled between the side sills and front side members, and a lower bar coupled to the side sills while being coupled to the rear lower members in a lateral direction of the vehicle body.

A vehicle body rear part structure includes a pair of rear side frames on left and right sides that extend substantially along a vehicle front-rear direction; and a rear floor panel to whose front part region, where a rear seat is disposed, the pair of rear side frames are combined. A rear part region of the rear floor panel is configured by a double panel structure having an upper wall and a lower wall. The rear part region of the rear floor panel extends further to a vehicle rear side than the pair of rear side frames. Each rear end part of the pair of rear side frames includes an inclined support part that inclines toward a vehicle front side toward an inner side in a vehicle width direction. The double panel structure is combined to the inclined support part of each of the rear side frames.

An embodiment sliding door mounting reinforcement structure includes a sliding door lower reinforcement configured to be mounted on a side of a vehicle body along a length direction of the vehicle body, the sliding door lower reinforcement including a guide rail mounted therein, the guide rail being configured to guide movement of a sliding door, and a center floor cross unit configured to be mounted in a width direction of the vehicle body, wherein the sliding door lower reinforcement and the center floor cross unit are combined.

A vehicle lower part structure includes a floor panel, a bracket fixed to the floor panel, and a component mounted on a lower side of the floor panel so as to be fastened by a fastener to the bracket. The floor panel has a convex portion. The bracket is provided so as to cover the convex portion from a lower side. The fastener includes a bolt and a nut. The bolt has a head located on a lower side of the bracket and a shaft extending upward from the head and inserted in a hole formed in the bracket. A distal end of the shaft is located in the internal space of the convex portion.

Impact protection structures for vehicles are described. An impact protection structure includes a support structure of the vehicle, an interior rail coupled to the support structure, and an exterior rail coupled to the interior rail. The exterior rail has an inboard boundary wall positioned between an upper mounting region and a lower mounting region. The upper and the lower exterior mounting region of the exterior rail are coupled to an upper and a lower mounting region of the interior rail. At least a portion of the inboard boundary wall is spaced apart from an outboard wall of the interior rail such that when the exterior rail is impacted by a blunt-object barrier, the inboard boundary wall of the exterior rail deforms, thereby damping energy of the impact at the exterior rail and arresting crack propagation between the exterior rail and the interior rail.

An automated vehicle includes a vehicle body defining a storage area located rearward of a rearmost vehicle seat in a front-rear direction of the automated vehicle. An interior structure is located in the storage area. The interior structure defines a storage compartment for housing an electronic component of the automated vehicle. The interior structure includes a removable floor panel overlying the storage compartment and a wall panel extended upward from the floor panel in a height direction of the automated vehicle. The storage compartment includes a dedicated space for the electronic component, the dedicated space located forward of a forward edge portion of the floor panel in the front-rear direction and between the wall panel and the rearmost vehicle seat in the front-rear direction.

An object of the present invention is to provide a battery protection member capable of achieving both securement of a capability to allow a passenger to reside in a vehicle and protection of a battery at the same time. According to one aspect of the present invention, a battery protection member includes a hollow-shaped battery containing frame extending in a vehicle lateral direction of the vehicle. The battery containing frame includes a surface where a seat occupied by a driver is disposed on an outer surface side thereof. The battery containing frame is configured to contain the battery on an inner surface side thereof.
