A passenger compartment support for an electric vehicle includes a front cross beam forming a portion of a firewall configured to separate a passenger compartment of the vehicle from a motor compartment of the vehicle. The cross beam has a left portion, a medial portion, and a right portion. The left and right are bent rearward relative to the medial portion. The left portion is coupled with a left structure of the electric vehicle and the right portion is coupled with a ride structure of the electric vehicle. A right crash beam is coupled with and generally orthogonal to a right medial portion. A left crash beam is coupled with and generally orthogonal to a left medial portion. A floor structure is coupled with a bottom of the cross beam. A rigid tunnel is coupled to a rear of the cross beam and a top of the floor structure.

A vehicle body structure includes a forecabin crossbeam and two front longitudinal beams disposed at intervals along a left-right direction. The forecabin crossbeam and the two front longitudinal beams are integrally formed and are at least partially located at the bottom of the front longitudinal beam.

A vehicle body structure and a vehicle are provided. The vehicle body structure includes a front longitudinal beam, a front compartment crossbeam, and a floor front crossbeam. The front longitudinal beam includes a left front longitudinal beam and a right front longitudinal beam that are disposed at an interval in a transverse direction. The front longitudinal beam is provided with a body section and a downward bent section connected to a rear end of the body section. The front compartment crossbeam is connected to the downward bent section of the left front longitudinal beam and the right front longitudinal beam, and is at least partially located below the body section. The floor front crossbeam is located behind the front compartment crossbeam at an interval, and is connected to the front longitudinal beam.

This vehicle body front structure includes a front side frame (14) which extends in a forward and rearward direction of a vehicle body, and a side wall member (52) which is provided outside the front side frame (14) in a vehicle width direction and joined to the front side frame (14), wherein the front side frame (14) has at least three folding portions, which include a first folding portion (24), a second folding portion (25), and a third folding portion (26) capable of being bent by an impact load (F1, F3) input from in front of a vehicle, in this order at intervals from a front toward a rear of the vehicle body, and has a reinforcing panel (65) which is provided between the second folding portion (25) and the third folding portion (26) among the side wall members (52), is stacked on a compression portion (81) on which a compressive force (F2, F4) acts from the impact load (F1, F3), and has a vertical bead (87).

A vehicle frame may comprise a plurality of interlocking tab and slot frame members forming a three-dimensional structure. A custom vehicle frame construction may be specified, designed and built based on a purchaser's selection. The three-dimensional structure may comprise a tab and slot panel to which additional tab and slot frame members are attached. The tab and slot frame members may have an attachment device disposed thereon for attachment of a vehicle component selected by the purchaser of the vehicle frame.

A power system for an electric vehicle including a firewall positioned between an engine compartment and a passenger compartment of the vehicle. A floor structure of the vehicle is coupled with the firewall and defines an aperture between the firewall and a central support beam of the floor structure. A battery assembly is configured to mount with an underside of the floor structure having a battery and a battery connector housing to house a battery connector. The connector housing defines an electric connector to couple with an electric system of the vehicle. The connector housing is inserted within the aperture of the floor structure such that at least a portion of the battery connector housing extends above the floor structure. A rigid tunnel is coupled with the firewall, the floor structure, and the central support beam to cover the portion of the connector housing that extends above the floor structure.

To provide a vehicle front body structure including a side sill that extends in a vehicle front-rear direction and is located behind a position where a front wheel is disposed and a torque box extending from a front end of the side sill toward an inside in a vehicle width direction. In the vehicle front body structure, the torque box includes an upper surface portion disposed at a substantially same height as an upper surface of the side sill and a lower surface portion disposed at a substantially same height as a lower surface of the side sill. A reinforcing member is provided in an internal space surrounded by the upper surface portion and the lower surface portion of the torque box.

A vehicle front portion structure includes: a dash cross-member extending in a vehicle width direction at a lower portion in a vehicle vertical direction of a dash panel, the dash panel being configured to partition between a power unit compartment provided at a vehicle front portion and a vehicle cabin, and the dash cross-member being a first framework member of which a cross-sectional shape when cut along the vehicle front-rear direction forms a first chamber portion between the dash cross-member and the dash panel; and a battery pack that extends in the vehicle width direction and the vehicle front-rear direction at the vehicle lower side of a floor panel that structures a floor portion of the vehicle cabin, a front end portion in the vehicle front-rear direction of the battery pack being joined to the dash cross-member.

A vehicle includes an electrical device, a frame member configured to hold the electric device, and a bracket connecting a vehicle structural member and the frame member. The frame member includes: a frame main body having an electrical device accommodation portion configured to accommodate the electrical device and a bracket attachment portion to which the bracket is attached; and an upper frame which is attached to the frame main body and covers the electric device accommodated in the electric device accommodation portion. The bracket attachment portion is attached to the bracket in a direction from the bottom to the top. The upper frame is attached to the frame main body in a direction from the top to the bottom.

Provided are a vehicle body and a vehicle. The vehicle body includes: a front longitudinal beam; a first bracket; an upper side beam having a front lower end connected to an outer end of the first bracket; a front floor longitudinal beam having a front end connected to a rear end of the front longitudinal beam and having a linear configuration; a rocker panel having a front end connected to the rear end of the front longitudinal beam; and a rear floor longitudinal beam connected to a rear end of the front floor longitudinal beam and a rear end of the rocker panel to make the front floor longitudinal beam, the rocker panel, and the rear floor longitudinal beam form a closed-loop force transmission structure.
