An under-protector fastening structure includes a bumper assembly coupled to a chassis frame, wherein the bumper assembly includes a bumper inner member and a bumper cover coupled to an outer side of the bumper inner member, and an under-protector coupled to the bumper inner member of the bumper assembly in a direction vertical to a length direction of a vehicle body, wherein the under-protector includes an under-protector mounting assembly coupled to the bumper inner member and an under-protector panel coupled to the under-protector mounting assembly, and wherein the under-protector mounting assembly includes a pipe member extending in the direction vertical to the length direction of the vehicle body, a mounting bracket coupled to the pipe member and the bumper inner member, and an under-protector fixing bracket having a first side coupled to the mounting bracket and a second side coupled to the under-protector panel.

A vehicle front portion structure includes a lower absorber installed in a lower region of a vehicle front portion and having a longer length in a width direction of a vehicle, at least one load bearing member disposed on a rear side of the lower absorber and connected to the lower absorber so as to receive a load transferred from the lower absorber, in which at least a part of the lower absorber is equipped with a reinforcement member, and the reinforcement member is formed, in cross section, in a shape of substantially a wave composed of a series of upward protruding parts protruded upward of the vehicle and downward protruding parts protruded downward of the vehicle, the upward and downward protruding parts alternating along the width direction of the vehicle.

A vehicle frame assembly includes, among other things, a lower main rail of a vehicle, a deflector assembly that is disposed adjacent a forward end portion of the lower main rail, and a positioning bracket of the deflector assembly. The positioning bracket is secured directly to the lower main rail and configured to separate from the lower main rail if a load that exceeds a threshold load is applied to a front of the vehicle.

A hybrid bumper assembly for a vehicle includes a steel reinforcement beam and aluminum crush cans attached to end portions of the steel reinforcement beam. The reinforcement beam has a multi-tubular shape that is formed by a high-strength steel sheet that is roll formed to provide at least two tubular portions. A crush can has an interfacing portion that is coupled to an end portion of the reinforcement beam. The end portions of the reinforcement beam and the interfacing portion of the crush cans may be configured to attach together using a select joining technology in a manner that minimizes or eliminates bimetallic or galvanic corrosion between the reinforcement beam and the crush cans.

A vehicle includes a hood at a front end, a frunk under the hood, and a cabin. The vehicle includes a cross-beam positioned between the frunk and the cabin, and configured to inhibit protrusion of the frunk into the cabin in a frontal impact. The vehicle also includes a frame and the cross-beam is coupled to the frame. The cross-beam is a unitary member that is coupled to the frame or the cross-beam includes two members separated by a gap and each member is coupled to the frame. The frame includes shock towers for coupling the cross-beam to the frame. The frame can also include a bracket for coupling the cross beam to the frame.

A vehicle front structure comprises a beam member positioned in front of a sub frame and having a closed-cross section extending in a vehicle width direction and a plate member extending forwardly from the beam member. The plate member comprises a fixation portion fixed to the beam member, a body portion extending forwardly from the fixation portion, and a front end portion positioned at a front end of the body portion and configured to have higher rigidity against a load applied in a longitudinal direction than the body portion. The front end portion of the plate member comprises an upper section located at a higher level than the body portion and a lower section located at a lower level than the body portion. The upper section is positioned on a vehicle forward side of the lower section.

A vehicle front structure comprises a beam member and a plate member. The plate member comprises a vertical face portion, a body portion extending forwardly from the vertical face portion, a front end portion positioned at a front end of the body portion, and a protrusion face portion provided to be forwardly spaced apart from the vertical face portion. The front end portion comprises an upper section located at a higher level than the body portion. The protrusion face portion comprises a protrusion-face-portion upper section located at a higher level than an upper end of the upper section and a protrusion-face-portion lower section located at a lower level than the upper end of the upper section. The protrusion-face-portion lower section is configured to have lower strength against a collision load applied from a vehicle forward side than the protrusion-face-portion upper section.

A vehicle front structure includes side frames in pairs, a bumper beam, a pair of lower frames, a lower beam, and wheels in pairs. Each of outer end parts of the bumper beam in a vehicle width direction and a corresponding one of outer end parts of the lower beam in the vehicle width direction overlap a corresponding one of the wheels as seen from the vehicle front side. In the vehicle width direction, a position of each of vehicle-width-direction outer ends of the bumper beam and a position of a corresponding one of vehicle-width-direction outer ends of the lower beam substantially coincide with a position of a mounting part of a corresponding one of brake devices that are disposed radially inside the wheels respectively.
