An automobile battery protection structure includes a middle channel; two protection components symmetrically disposed on the left and right of the middle channel Each of the protection components includes a vehicle door sill, a seat beam assembly, a floor panel, and a longitudinal beam. One end of the seat beam assembly is attached to the upper part of the vehicle door sill, and the other end of the seat beam assembly attached to the upper side of the middle channel. One end of the floor panel is attached to the lower part of the vehicle door sill, and the other end of the floor panel is attached to the bottom side of the middle channel. The longitudinal beam is located under the floor panel, and longitudinally extending through the vehicle body. A car battery pack disposed under the middle channel.

A frame assembly for a vehicle includes a rocker elongated along an axis and defining a tubular cavity elongated along the axis. The vehicle frame assembly includes a sealed pressurized insert disposed in the cavity and elongated along the axis. The sealed pressurized insert increases the stiffness of the rocker, i.e., decreases the likelihood of deformation of the rocker during an impact of the vehicle, such as a side impact.

A structural member is provided that includes a steel sheet with a tensile strength of 980 MPa or higher overlying another metal plate and joined thereto by welding, where a break initiating near a welded portion is less likely to be produced. A structural member (10, 10a, 10b, 10c) includes: a first member (1), the first member being a steel sheet with a tensile strength of 980 MPa or higher; a second member (2) overlying the first plate (1), the second member being a metal plate; a plurality of welded portions (3, 31, 32); a plurality of heat-affected zones (5, 51, 52) each formed to surround the corresponding one of the welded portions (3, 31, 32), the heat-affected zones having a Vickers hardness lower than that of the first member by 50 HV or more. A pair of edge sections (4) of the first member (1) are provided between adjacent heat-affected zones (5, 51, 52). The pair of edge sections (4) of the first member located between the adjacent heat-affected zones (5, 51, 52) extend to cross a line (LC1) linking the adjacent welded portions (3, 31, 32).

A vehicle rollover simulator is provided. The rollover simulator includes a cage assembly that is rotationally suspended in a frame assembly. A transmission motor assembly is removably connected to the frame assembly and to the cage assembly to rotate the cage assembly to an inverted position for training. A brake assembly is provided that prevents rotation of the cage assembly and significantly enhances stability. The assemblies of the simulator can be disassembled and are sized to be readily carried by hand through typically dimensioned doorways, hallways and stairwells such that manually moving the rollover simulator is readily accomplished.

A chassis frame module for an electric vehicle may include a chassis frame including a pair of side frames, a pair of inclined frames connected to front ends of the respective side frames, respectively, and a distance between the pair of inclined frames decreases toward the front, a front frame connected to the inclined frames, and a rear frame connected to rear ends of the pair of side frames, a battery disposed between the pair of side frames, and a plurality of wire assemblies disposed between the side frame and the battery and in a longitudinal direction of the side frame, and being configured to house a wire in an internal space thereof.

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 vehicle body, preferably for a motor vehicle with four wheels, includes two side members extending in the longitudinal direction of the vehicle, at least one support, which extends in the vehicle transverse direction between the two side members, and at least one molded foam part that reinforces the vehicle body. The foam part is arranged in a lateral structure of the vehicle body at the height level of the support.

A side sill is configured from a side sill outer element comprising an outer upper wall, outer lower wall, an outer side wall, an outer upper flange and an outer lower flange, and from a side sill inner element comprising an inner upper wall, an inner lower wall, an inner side wall, an inner upper flange and an inner lower flange. On the lower end, a pillar has a joint portion held between and joined to the outer upper flange and the inner upper flange, and a first extension part and a second extension part extending from the joint portion into the closed section of the side sill, and includes an extension, the top end of which is joined to the first extension part and/or the second extension part and the bottom end of which is held between and joined to the outer lower flange and the inner lower flange.

A vehicle battery mounting structure has: a battery frame lower member that is made of resin, and that is disposed at vehicle transverse direction inner sides of energy absorbing members provided at a lower side of a floor panel, and that, together with a battery frame upper member, structures a battery frame that supports a battery; a lower ductile member having a lower main body portion that is joined to vehicle transverse direction outer side end portions of the battery frame lower member, and lower flange portions that are fixed to a bottom surface side of the floor panel; and inclined walls that are formed at vehicle transverse direction outer side end portions of the battery frame lower member, and that are inclined from vehicle transverse direction outer upper sides toward vehicle transverse direction inner lower sides.

A vehicle battery mounting structure includes: an energy absorption member that is provided at a vehicle body lower side of a floor panel, and that includes a first side wall portion sloping toward a vehicle body upper outside at a vehicle width direction inside of the energy absorption member, as viewed from a vehicle body longitudinal direction; and a battery frame made of resin that is disposed at the vehicle width direction inside of the first side wall portion, that supports a battery, and that includes a second side wall portion sloping toward the vehicle body upper outside at the vehicle width direction outside of the battery frame, as viewed from the vehicle body longitudinal direction, and facing the first side wall portion in the vehicle width direction.
