Abstract: A vehicle body structure can include a dash panel, a side sill including a first side sill and a second side sill, respectively connected to both sides of the dash panel, a first cross member located above the side sill and coupled to the dash panel, a second cross member coupled to the dash panel and connected to the side sill, and a connection member connecting the first cross member and the second cross member, wherein the connection member includes a first connection member and a second connection member, wherein the second connection member is spaced apart from the first connection member.

Abstract: A reinforcement structure for a rear floor of a vehicle includes a rear floor panel, a first cross member extending along a vehicle width direction to be combined with a rear end of the rear floor panel, a side member combined with a side portion of the rear floor panel, a side seal combined with the side member, an extension panel combined with a rear end of the rear floor panel and including a tunnel portion, and a second cross member extending along the vehicle width direction and being combined with the first cross member and the side member, wherein the first cross member and the second cross member are directly combined with the extension panel, and one end of the second cross member is bent to be combined with the first cross member, and the first cross member and the second member form a ring shape at both sides of the tunnel portion.

Abstract: 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.

Abstract: A reinforcement structure for a rear floor of a vehicle includes a rear floor panel, a first cross member extending along a vehicle width direction to be combined with an upper end of the rear floor panel, a side member combined with a side portion of the rear floor panel, a side seal combined with the side member, an extension member combined with an upper end of the rear floor panel and including a tunnel portion, and a second cross member extending along the vehicle width direction and being combined with the first cross member and the side member.

Abstract: A vehicle prototype for a crash test includes a vehicle coupling part connected to a test specimen, which is a part of an actual vehicle body. A main body is connected to the actual vehicle coupling part and crashes together with the test specimen.

Abstract: An automotive wheel separation mechanism may include a hitting member that hits and breaks a lateral arm connecting a wheel to a vehicle body by being pushed back in the longitudinal direction of a vehicle due to a shock force from the outside in a front collision, and an anti-sliding protrusion that is disposed on the lateral arm to prevent the hitting member hitting the lateral arm from sliding on the lateral arm.
