An overall knuckle is formed by a second carbon-fiber composite material, and a first carbon-fiber composite material is embedded in particular portions, whose rigidities are insufficient only with the second carbon-fiber composite material. The one particular portion is provided to a neck part, and the first carbon-fiber composite material is embedded in this particular portion such that continuous fibers thereof are orientated in a direction orthogonal to a central axis of a torsional load so as to enhance a torsional rigidity. The other particular portions are provided to the body part, and the first carbon-fiber composite material is embedded in these particular portions such that the continuous fibers thereof are orientated in a vertical direction so as to enhance a bending rigidity.

The present disclosure provides a vehicle roof structure including: a left and right pair of roof side rails configuring part of a roof section of a vehicle body, the roof side rails are supported by a center pillar configuring part of the vehicle body and extend along a vehicle front-rear direction; a roof reinforcement portion formed of fiber reinforced plastic, the roof reinforcement portion disposed between the roof side rails so as to extend along a vehicle width direction; and a coupling section formed of metal, the coupling section couples the roof side rails and the roof reinforcement portion, and includes a weak section, the weak section deforms under a collision load in the vehicle width direction prior to the roof reinforcement portion undergoing bending deformation under the collision load.

A tonneau cover access panel assembly connectable to a tonneau cover assembly that eliminates the need for side rails to both locate and tension the top cover. The tension works to seal out environmental elements and holds the tonneau cover and locating bows of the tonneau cover in place. The tonneau cover access panel holds the rear of the tonneau in the closed tension state keeping the tonneau secured and tight until the cover is opened by an operator. The tonneau cover access panel assembly is movable between a closed position and a fully open position, and, is movable between at least a first open position and the closed position for more limiting access to the cargo bed of the vehicle when desired. The tonneau cover access panel assembly also reduces weight and complexity.

A box beam bicycle structure (BBBS) having a box section, a right triangular section and a left triangular section. The right and left triangular sections are either integral with the box structure, or the triangular sections are attached to the box structure by riveting, bonding or welding. The box structure is preferably made of a sheet material and the parts that comprise the box structure are attached together by riveting, bonding or welding. The BBBS interfaces with bicycle components to function as a lightweight, strong bicycle frame. Additionally, the BBBS can be manufactured as a one-piece design, or can utilize a hybrid construction design with an internal structure and reinforcing members at areas of high stress.

A tonneau cover access panel assembly connectable to a vehicle that eliminates the need for side rails to both locate and tension a tonneau cover. The assembly also reduces weight and complexity. The assembly incorporates a readily accessible rear latching system that reduces or eliminates interference with the tonneau cover during operation. The assembly also incorporates a tonneau cover tensioning system. The tension seals out environmental elements and holds the tonneau cover and locating bows in place. The assembly holds the tonneau in the closed tension state keeping the tonneau cover secured and tight until the cover is opened by an operator. The assembly is movable between a closed position and a fully open/stowable position and any intermediate positions. The assembly is also movable between at least a first open position and the deployed position for more limiting access to the cargo bed of the vehicle when desired.

A method includes molding an outer impact beam made of carbon fiber reinforced plastics (CFRP) and separately molding an inner impact beam made of CFRP. The outer impact beam and the inner impact beam are coupled to each other to form an impact beam and the impact beam is coupled to an inner panel of a vehicle door.

A method of making a side step of a vehicle includes a bracket that is mounted to a vehicle body and an insert main body that bears weight of passengers. The bracket and the insert main body are integrally provided by using a CFT material through insert-molding, and an injection molding resin is coupled to all over the insert main body where the bracket is coupled through insert-molding so as to form a main frame of the side step.

An axle carrier for a motor vehicle is disclosed having at least two attachment points, a metallic upper shell and a lower shell of fiber composite material coupled to the metallic upper shell. A first load path extending through the metallic upper shell between the at least two attachment points in an edge region, and a second load path shorter that the first load path extending through the lower shell.

Disclosed is an electric vehicle, comprising a chassis (1), a vehicle body and a power battery (71), wherein the chassis (1) comprises a frame system (2), a steering motor damping system (13) mounted on the frame system (2), a wheel system (12) connected to the steering motor damping system (13), a steering system (3) mounted on the frame system (2), and a braking system (4) mounted on the frame system (2); and the wheel system (12) comprises a left front wheel (121) using a hub motor, a left rear wheel (123) using a hub motor, a right front wheel (122) using a hub motor, and a right rear wheel (124) using a hub motor. Driving the wheels (121, 122, 123, 124) with the hub motors can omit a traditional mechanical transmission system, so as to simplify the structure of the chassis (1) and reduce the weight of the chassis (1). Compared with a traditional electric vehicle, the electrical vehicle has a lighter weight, smaller volume, reduced mechanical transmission loss, and improved electrical energy utilization rate.

An impact beam structure of a CFRP door for a vehicle is disclosed. A outer impact beam and an inner impact beam are separately molded and then coupled to each other such that an impact beam is formed. The impact beam is coupled to an inner panel of the CFRP door for the vehicle.
