A vehicle body front reinforcement assembly includes: a front side beam connected to a front of a dash panel; a side sill connected to a side end portion of a floor panel; and a torque box extending from the dash panel to the side end portion of the floor panel and connecting a rear end of the front side beam to a front end of the side sill, wherein the side sill includes: a side sill coupler coupled to a rear end of the torque box; and a side sill extension connected to a rear end of the side sill coupler and extending towards the rear of a vehicle, and wherein the side sill coupler is made of a material having a lower tensile to strength than the material of the side sill extension.

A modular utility vehicle construct that is light weight yet robust is provided. The construct is formed with a composite open area core sandwich structure capable of withstanding typical wear and tear and environmental elements experienced by utility vehicle compartments. The use of the composite sandwich structure allows for replacement of traditional materials such as steel or aluminum, without a loss of strength, in a vehicle's containment construct while also reducing the overall weight of the vehicle and increasing the ability to customize the vehicle's utility features to suit the specific needs of the purchaser.

A front vehicle-body structure includes a floor panel; a side sill; a floor frame extending in a front-rear direction on a vehicle-width-direction inner side of the side sill; a first cross member connecting a front portion of the side sill to the floor frame in a vehicle width direction; and a second cross member connecting the side sill and floor frame in the vehicle width direction on a rear side of the first cross member. The floor panel has a quadrilateral closed region surrounded by the side sill, the floor frame, and the cross members, on a periphery of the closed region, and the closed region has a bead linearly extending in a direction intersecting with a virtual line connecting front and rear portions on vehicle-width-direction outer and inner sides, respectively, of the closed region to each other at an angle of 45 degrees or more in plan view.

A connection structure of an electric vehicle includes a cross member provided in a width direction of a vehicle body, a side member provided in a vehicle body length direction, and a joint member inserted into the cross member and connected to the side member. The joint member includes an insert portion inserted into the cross member, and a clamping portion connected to the side member.

A vehicle includes a vehicle frame having a first frame rail and a second frame rail spaced from each other. The vehicle frame includes a cross-member extending from the first frame rail to the second frame rail. A battery enclosure extends from the first frame rail to the second frame rail. The battery enclosure includes a first side member and a second side member. The first side member is connected to and deformable relative to the first frame rail. The second side member is connected to and deformable relative to the second frame rail. The battery enclosure includes a reinforcement connected to the first side member, the second side member, and the cross-member.

A battery mounting structure is provided to prevent water intrusion into a clearance between a battery pack and a floor panel of a vehicle. The battery mounting structure comprises: frame members extending longitudinally on both sides of the vehicle; a floor panel disposed between the frame members; and a battery pack situated underneath the floor panel. A sealing member is interposed between a periphery of the battery pack and a portion extending from a member opposed to the battery pack, and a drain hole is formed in the sealing member to connect an inner side and an outer side of the sealing member.

A battery mounting structure for maintaining a sufficient passenger compartment in vehicles is provided. The battery mounting structure comprises a pair of longitudinal side sills (11, 12), and a battery pack (7) disposed between the side sills (11, 12). A plurality of battery modules (9) are juxtaposed in a casing (8) of the battery pack (7). A linear depression (39) protrudes downwardly from a reinforcement member (15) situated underneath a floor panel (17) supported by the side sills (11, 12), and the battery pack (7) has a linear depression (38) hold the linear depression (39) therein.

A vehicle body frame includes: side frames that have at least inner walls that are disposed at vehicle transverse direction inner sides and upper walls that are disposed at vehicle body vertical direction upper sides, and that are formed as closed cross-sectional structures, and that extend in a vehicle body longitudinal direction, and that are fastened and fixed to under members that are disposed at a vehicle body lower side of a floor panel; and an upper frame that is disposed further toward a vehicle transverse direction inner side than the inner walls and at a height that is lower than the upper walls, and at which an installed object is installed.

A motor vehicle body includes a side sill and a pillar arranged on the side sill, which has a cross section with a first side and a following second side in a vehicle longitudinal direction. A cross member is attached to the side sill. A sill-side end section of the cross member includes a side wall following a first side wall of the end section in the vehicle longitudinal direction. The distance of the first side wall in the vehicle longitudinal direction towards the second side of the cross section of the pillar decreases in a vehicle transverse direction towards the side sill at least locally in regions. An upper cover wall is connected to a connection section of the cross member. The distance of the upper cover wall decreases in a vehicle vertical direction towards the pillar in the vehicle transverse direction at least locally in regions.
