A system and methods are provided for a wing stabilizer charging system for recharging onboard batteries during operation of an electrically powered vehicle. The wing stabilizer charging system comprises a wing stabilizer configured to be coupled with a rear of the vehicle. One or more air inlets are disposed in the wing stabilizer and configured to receive an airstream during forward motion of the vehicle. Wind turbines are disposed within the wing stabilizer and configured to be turned by the airstream. A circuit box is configured to combine electricity received from the wind turbines into a useable electric current. A power cable extends from the circuit box and is configured to supply the useable electric current to any one or more electronic devices, such as any of an onboard battery for powering the vehicle, mobile phones or smart phones, portable music players, tablet computers, cameras, and the like.

An automotive vehicle includes a body with a front portion and a rear portion. The vehicle additionally includes a spoiler coupled to the rear portion. The spoiler includes a first portion, a second portion, and a cap. The first portion includes a first plastic material, the second portion includes a second plastic material, and the cap includes a third plastic material. The second plastic material is distinct from the first plastic material. The second portion is disposed between the first portion and the cap. The second portion has a through hole extending therethrough. The cap has a diameter exceeding that of the through hole. The first portion and the cap are welded together via the through hole to mechanically secure the second portion to the first portion.

The present disclosure provides a vehicle spoiler, which can stabilize the airflow passing through the vehicle, thereby improving the aerodynamic performance. The vehicle spoiler includes a plurality of skin portions arranged along the front-rear direction of the vehicle and overlapping each other in sequence in the front-rear direction of the vehicle; and a plurality of movable portions respectively supporting the plurality of skin portions and movable in the front-rear direction of the vehicle. The plurality of skin portions change the overall length in the front-rear direction of the vehicle through movement of at least one of the plurality of movable portions in the front-rear direction of the vehicle. Moreover, the plurality of skin portions are maintained to overlap in the movable range of the plurality of movable portions.

A method to control a high performance road vehicle equipped with a rear spoiler that has at least one adjustable aerodynamic profile, the control method includes the steps of: detecting the tendency to oversteer or understeer when cornering, adjusting the setting of the adjustable aerodynamic profile of the rear spoiler to a greater angle of incidence in order to increase the overall downforce generated by the rear spoiler if oversteering is detected when cornering, and adjusting the setting of the adjustable aerodynamic profile of the rear spoiler to a lower value of the angle of incidence in order to reduce the overall downforce generated by the rear spoiler if understeering is detected when cornering.

A deflector device includes a deflector body that is configured to be deployed in front of a front wheel of a vehicle by being rotated in a deploy direction and to suppress airflow onto the front wheel, and that is configured to be stowed in a body of the vehicle by being rotated in a stow direction; a drive member that is configured to transmit drive force; and a transmission member that is provided with a projection that protrudes in a radial direction thereof and that is configured to be engaged with the drive member such that drive force from the drive member is transmitted to the transmission member and the deflector body is rotated.

The disclosure provides a vehicle lower structure, which is used to change the air resistance of the vehicle bottom. The vehicle lower structure includes: a plurality of strakes, disposed in front of a wheel when viewed from a front of the vehicle; and at least one strake of the plurality of strakes, disposed to be movable in an up-down direction. The vehicle lower structure includes: a plurality of strakes, disposed in front of a wheel when viewed from a front of the vehicle; and at least one strake of the plurality of strakes, disposed to be movable in a front-rear direction.

The invention provides a movable spoiler device, which may be easily stored and operated stably. The movable spoiler device includes a fixed plate fixed on a body of a vehicle; a movable plate disposed to be movable between a storage position connected to the fixed plate and an unfolding position closer to the rear position than the storage position; a linkage mechanism that is pivotally supported on the fixed plate at one end and pivotally supported on the movable plate at the other end; a sliding mechanism including a track portion disposed on one of the fixed plate and the movable plate, and a sliding portion disposed on the other of the fixed plate and the movable plate; and an actuator driving the linkage mechanism or the sliding mechanism to drive the movable plate to move relative to the fixed plate.

A vehicle substructure includes at least one wing device for producing at least one underflow and at least one overflow from inflowing air to improve a downforce, the at least one wing device having at least one air-guiding apparatus for dividing the inflowing air into at least one wing air flow for the underflow of the wing device and into at least one structure air flow for at least one vehicle component. The air-guiding apparatus includes at least one adaptable air-guiding element. A dividing ratio of the at least one wing air flow and the at least one structure air flow can be flexibly set by at least one adaptation of the air guiding element.

A server is configured to store a number of different models of an object in machine-ready form corresponding to a number of different three-dimensional printers having differing capabilities and/or hardware configurations. When a user at a client device or a printer requests the object, the server automatically determines a printer type and selects a suitable, corresponding machine-ready model for immediate fabrication by the printer.

A rear spoiler device for a vehicle at least includes an air-guiding element (25) for lengthening the contour, in particular of a side surface (3) of the vehicle (1), in a travel position, and a displacement device for displacing the air-guiding element (25) between the travel position and a home position. A front end (54) of the air-guiding element (25) is provided for bearing against the side surface (3) of the vehicle (1) in the travel position. At least one sealing element (61) for sealingly bearing against the side surface (3) is provided on the front end (54) of the air-guiding element (25), and the displacement device is provided for pressing the sealing element (61) against the side surface (3) in the travel position.
