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.

Abstract: An electrically powered motor vehicle for transport of goods, of the minivan type, includes a main frame, a front axle assembly and a rear axle assembly. The main frame includes a front frame subassembly, a floor-panel subassembly, a rear frame subassembly, and a top frame subassembly. Each of these frame subassemblies includes a lattice structure including box-section elements made of steel, preferably high-strength steel. Each of the frame subassemblies is prearranged for being preassembled separately and subsequently assembled together with the other subassemblies so as to constitute the main frame. The structure is such as to afford high flexibility of production, and presents at the same time considerable safety characteristics, thanks to a high capacity of absorption of impact energy. The motor vehicle is equipped with a transporting body having a hollow-walled body made of plastic material, filled with foamed plastic material, preferably obtained with the rotational-molding technique.

Abstract: A seat assembly for a motor vehicle includes: a supporting structure, designed to be mounted on the floor panel of the motor vehicle; a seat, which is mounted on the supporting structure and includes a sitting portion and a backrest portion; and an airbag unit, including at least one airbag, which is folded into a housing provided in the seat assembly and is inflatable into an expanded condition outside the housing, whereby the at least one airbag has a conformation such that, in the expanded condition, the at least one airbag identifies a protection wall that surrounds the backrest portion of the seat.

Abstract: An air-heating blower device for a passenger compartment of a motor vehicle comprising a body with at least one inlet opening at least one outlet opening an electrically driven axial fan rotatably mounted around its axis within the body. The fan is associated to an electric motor (M) with toroidal geometry, having an annular rotor which is rotatable within an annular stator and defining a central opening inside thereof, said fan (F) having one or more blades (B) which are carried by the rotor and each blade extending into said central opening towards a free end of the blade which terminates at a distance from the central axis of the fan, and in that the annular body of the rotor and/or the annular body of the stator define a guide tube for the airflow activated by the fan (F) over the resistive electric heater (H).

Abstract: A motor-vehicle frame includes a pair of longitudinal members; a plurality of cross members, which join the longitudinal members to one another; a resting surface, which is supported by the longitudinal members and cross members and defines the surface of the floor of the passenger compartment of the motor vehicle; a pair of front uprights; and a front-seat assembly. The frame includes a platform structure, arranged on which is the front-seat assembly, which affords a greater comfort within the passenger compartment and moreover strengthens the overall structure of the motor vehicle.
