A reinforcing structure of a vehicle frame member includes: ribs that integrally connect standing wall portions, that are formed at a planar portion of a vehicle frame member, to one another, and that reinforce the planar portion; portions of gradually changing thickness that are formed at connected portions of the ribs with the standing wall portions; portions of gradually changing height that are formed at the connected portions of the ribs with the standing wall portions; first curved portions that are formed at the portions of gradually changing thickness; second curved portions that are formed at the portions of gradually changing thickness; third curved portions that are formed at the portions of gradually changing height; and fourth curved portions that are formed at the portions of gradually changing height.

An engine mount for a drive unit in a vehicle includes a bracket having first and second joining points for attachment of the bracket to the drive unit. A first mounting member connects the bracket to the drive unit in the first joining point along a first joining axis. An engine mount is arranged on a vehicle body and supports the drive unit via the bracket. A second mounting member connects the bracket to the drive unit in the second joining point along a second joining axis. The first and second joining axes extend at a slant to each other by an axis angle.

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.

A work vehicle includes a cabin to cover an operator's seat on a traveling body. A cabin frame that constitutes a framework of the cabin includes a pair of left and right front pillars, a pair of left and right rear pillars, a front beam, a rear beam, and side beams. The front beam couples upper end portions of the front pillars to each other. The rear beam couples upper end portions of the rear pillars to each other. Each of the side beams couples to each other upper end portions of each of the front pillars and each of the rear pillars that stand at a front and rear. The rear beam is formed to have a U-shaped cross-section by presswork of a metal plate material.

Provided is a method for fastening a separation type tricycle in which a connecting pipe for connecting a front wheel part and a rear wheel part can be separated from and fastened to a head tube of the front wheel part, wherein the front wheel part and the rear wheel part are separated from each other by forming an ear-shaped groove, in which a handle bar can be put, in a right-side-open rectangular shaped plate fixed to the end of the connecting pipe so as to be used for attachment/detachment in a fastening device of the head tube, and then the end of a connecting bar for connecting the front wheel part and the rear wheel part is put on the handle bar by using the groove and another place is fixed thereto so as to set three wheels at the shortest distance therewith, thereby conveniently moving and storing the tricycle.

An air duct for a vehicle is provided. The air duct includes a first duct component that is formed from a rigid material through which air external air is introduced. A second duct component is formed from a pliable material through which introduced air is discharged towards an air filter. The second duct component is formed integrally with the first duct component.

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 vehicle body structure includes a first middle floor unit for a gasoline vehicle and a second middle floor unit for a hybrid vehicle, and the first and second middle floor units are made interchangeable with each other. A front floor unit and a rear floor unit are made shareable by the gasoline vehicle and the hybrid vehicle. That is, the front floor unit and the rear floor unit can be regarded as a platform. Additionally, the second middle floor unit includes a housing, and an IPU is stored in an interior of the housing.

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.

There is provided a vehicle body front structure in which left and right frame side mounting members for connecting the rear ends of left and right bumper beam extensions are provided at the front ends. The left and right front side frames are formed from left and right side inner panels and left and right side outer panels. The left and right side outer panels are formed from left and right rear outer panels and left and right front outer panels. The left and right front outer panels are formed from left and right side plates, left and right upper plates, and left and right lower plates. At least one of the set of the left and right upper plates and the set of the left and right lower plates is formed by members different from the left and right side plates.
