Abstract: An aircraft, in particular a personal air mobility aircraft or a drone, having one or more annular propellers, with one or more blades extending radially from a rotor ring body towards the axis of the rotor ring, and one or more belt transmissions, which connect the rotor ring of each annular propeller with the output shaft of a motor unit including an electric motor. Various aircraft configurations include a vertical take-off and horizontal flight configuration. The aircraft surfaces are covered by groups of photovoltaic solar cells connected to a main battery pack for powering the electric motors that drive the annular propellers, and to an auxiliary electric battery for powering the on-board electrical circuit.

Abstract: A drone or an aircraft for personal air mobility includes at least one horizontal planar structure having four ducted propeller rotors with vertical axis, which are substantially coplanar with each other. Each of the rotors has a rotating ring rotatably mounted within a circular opening. The rotating ring is configured as to define an annular wall for ducting of air flow produced by the rotor. Each of the rotors has one or more blades which extend towards the central axis of the rotor, and have tips terminating at a distance from the axis of the propeller, such that each rotor is an annular propeller. The rotating ring of each rotor is controlled by an actuator.

Abstract: A battery pack for the propulsion of electric road, boat or aircraft vehicles, includes a plurality of battery modules. The battery cells of the pack are arranged with their planes oriented horizontally, according to a “lasagna” configuration, over a lower tray. Superimposed layers of cells are provided, separated by aluminum sheets, which hinder the propagation of heat and flame. Between the cells there are tubes of a circuit for a coolant or alternatively a cooling panel is provided under the cell layers. The cells have one side glued to an adjacent aluminum sheet and the opposite side also glued to an adjacent aluminum sheet or covered by a pad of elastically deformable material. The terminals of some cells side-by-side are connected to each other by means of bars held in position by clamps, with an arrangement such as to simplify the assembly procedure.

Abstract: A ride-on vehicle, in particular a bicycle or a three-wheel vehicle, more in particular a purely electric or pedal assist bicycle or three-wheel vehicle, which includes an electrically-driven air conditioning unit is carried by the frame of the vehicle. An auxiliary supporting structure is connected to the frame of the vehicle , and in one example includes two rear uprights transversally spaced apart from each other, extending above the saddle, and continuing into two upper beams and then into two front uprights, whose lower ends are connected to a frame portion which extends in front of the handlebar. there An air guiding structure is associated to the auxiliary supporting structure and is in communication with an outlet of the air conditioning unit and has one or more outlets for the flow of conditioned air, which are configured for directing jets of conditioned air towards and/or around a body of a user.

Abstract: An electric-propulsion car includes: a main frame, a front axle unit, a rear axle unit, wherein the axle units each have an auxiliary frame for supporting the axle units and two suspension units that connect two respective wheel supports to the supporting auxiliary frame, wherein at least one of the axle units is a motorized axle with steering wheels including, mounted on said auxiliary frame, an electric motor for actuating the rotation of the wheels, a control unit for controlling said electric motor, a transmission unit for connecting the electric motor to the wheels, and a steering device for steering the wheel supports, and wherein each one of the main frame and auxiliary frames includes a reticular lattice structure including boxed elements made of steel, each one of the main frame and auxiliary frames being adapted to be pre-assembled separately and then assembled together.
