Apparatus, system, and method of providing a bumper for a robotic vehicle
An apparatus, system and method capable of providing a bumper capable of providing decreasing reversionary impact forces upon an impacting collider as the bumper is compressed. The apparatus, system and method may include at least a bumper cover; and a scissor mechanism housed within the bumper cover. The scissor mechanism may comprise a forward extension member proximal and having a parallel axis that is at least substantially parallel to a parallel tangential axis of the bumper cover; a rear extension member substantially parallel to the forward extension member, and distal from the flexible bumper; at least left and right long scissor members that are rotatably and slidably associated with respective slots in the forward extension member, and that, are rotatably associated with the rear extension member; and at least left and right short scissor members that are rotatably associated with the front extension member, and that are rotatably associated with a respective one of the left and right long scissor members.

THERMOMECHANICAL AGEING FOR 6XXX EXTRUSIONS
The present invention relates to extrusions for structural components, such as bumper, side impact beam, seat sill in vehicles and more particularly to a method for optimizing strength and energy absorption of 6XXX aluminium alloys extrusions by variations in thermomechanical ageing (TMA) consisting in i) an artificial preageing treatment with a duration t1 at a temperature T1 selected to increase the yield strength of said extrusion between 5% and 20%, said temperature T1 being typically between 120° C. and 180° C. and said duration t1 being typically between 1 and 100 hours, to obtain an artificially preaged extrusion, ii) a plastic deformation of said artificially preaged extrusion between 1% and 80% to obtain a deformed extrusion, iii) a final artificial ageing treatment of said deformed extrusion with a duration t2 at a temperature T2, said temperature T2 being typically between 140° C. and 200° C. and said the duration t2 being typically between 1 and 100 hours.

Front vehicle-body structure of vehicle
A front vehicle-body structure of a vehicle includes: side frames of a suspension subframe; a cross member connecting front-end portions of the side frames in the vehicle width direction; a front beam member; and a connecting member connecting a front-end portion of each side frame to the front beam member. A high-rigidity portion having a higher rigidity than other portions of the side frame is at a connecting portion between the front-end portion of the side frame and the cross member. The front beam member has a side end portion extending on a vehicle-width-direction outer side relative to a connecting position with the connecting member. A protrusion portion protruding from the side end portion toward a vehicle rear side is to come into contact with the high-rigidity portion from the vehicle-width-direction outer side when a collision load from a vehicle front side is input to the side end portion.
VEHICLE FRONT STRUCTURE
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.
VEHICLE FRONT STRUCTURE
A vehicle front structure includes side frames in pairs, a bumper beam, lower frames in pairs, and a lower beam. The lower beam extends in a vehicle width direction on a vehicle lower side of the bumper beam. The lower beam is coupled to vehicle-front-side end parts of the lower frames. The lower beam includes a front lower beam member and lower beam members in pairs. The front lower beam member constitutes a vehicle-front-side part of the lower beam. The front lower beam member extends in the vehicle width direction. Longitudinal-direction end parts of the front lower beam member are disposed outward in the vehicle width direction, as seen from the lower frames. The rear lower beam members constitute a vehicle-rear-side part of the lower beam. The rear lower beam members are joined respectively to both of the longitudinal-direction end parts of the front lower beam member.
