The present disclosure relates to a chassis (300) for a vehicle, the chassis (300) comprising a plurality of sandwich plate elements (100) and a plurality of connection elements (200), wherein the sandwich plate elements (100) each comprise a plate core (150) and a first and second plate skin (110, 120) and wherein each connection element (200) comprises two or more recesses (210, 220), each recess (210, 220) being adapted to receive an edge portion (160) of one of the plurality of sandwich plate elements (100) such that at least a portion of the sandwich plate element (100) interacts with the recess (210, 220), thereby connecting said plurality of sandwich plate elements (100) to form said chassis (300). The disclosure also relates to a vehicle comprising a chassis (300), a method for forming a chassis (300) and a kit of parts for assembling a chassis (300).

An additively manufactured node is disclosed. A node is an additively manufactured (AM) structure that includes a feature, e.g., a socket, a channel, etc., for accepting another structure, e.g., a tube, a panel, etc. The node can include a node surface of a receptacle extending into the node. The receptacle can receive a structure, and a seal interface on the node surface can seat a seal member between the node surface and the structure to create an adhesive region between the node and the structure, the adhesive region being bounded by the node surface, the structure, and the seal member. The node can also include two channels connecting an exterior surface of the node to the adhesive region. In this way, adhesive can be injected into the adhesive region between the node and the structure, and the adhesive can be contained by the seal member.

A unit of a combined front bumper beam and front end module (CFF unit) is provided with a configuration in which an impact energy absorbing space formed is as a closed space and a chassis component mounting space is formed as an open space. The impact energy absorbing space and the chassis component mounting space are formed as an integrally formed structure. This structure is divided into a bumper back beam to which impact energy is transmitted, a crash box molded integrally with the bumper back beam to form the impact energy absorbing spaces at both sides of the bumper back beam, respectively, and a front end module carrier (FEM carrier) molded integrally with the crash box to form the chassis component mounting space at the inward side of the crash box. The bumper back beam, the crash box and the FEM carrier form the CFF unit.

A vehicle body is disclosed. The vehicle body includes a lateral sill panel device made of fiber-reinforced plastic, which is formed as a hollow profile with an external wall element as an impact face, and a floorpan structure including a transverse seat support made of fiber-reinforced plastic, which extends in the Y-direction of the vehicle body substantially to the external wall element.

The present invention relates to a modular way to build a rolling chassis using composite materials without custom forming, and yielding appropriate weight distribution (centre of gravity) and torsional and bending rigidity.

A vehicle load-bearing structure includes a cell made of composite materials and composed of a plurality of components joined to each other by at least one joining system to form a single structure; the cell is made up of a number n of components between 3 and 8, that is 3<n<8.

A method for producing a node structure includes providing at least two pre-manufactured profile components having respective profile ends provided with corresponding abutment surfaces; positioning the profile ends in a pressing tool so that a homogenous gap is formed between the abutment surfaces; performing a pressing process in the presence of a fiber-containing plastic mass in the pressing tool for generating a connecting node that form fittingly connects the profile ends, wherein the fiber containing plastic mass also enters into the gap.

In certain embodiments, an electric vehicle includes a front cage, a rear floor, an intermediate section, a utility cabinet, and a flatbed. In other embodiments, an electric vehicle includes a front cage, a rear floor, an intermediate section, and a flatbed. In some embodiments, the front cage at least partially defines an operator cabin, the rear floor is positioned rearward of the front cage in a longitudinal direction, and the intermediate section is disposed at least partially between the front cage and the rear floor in the longitudinal direction.

Land vehicles, modular systems for forming monocoques of land vehicles, and methods of forming monocoques of land vehicles using modular systems are envisioned. In certain embodiments, the land vehicles are provided as delivery vehicles and/or utility vehicles. A land vehicle includes a monocoque supporting a plurality of wheels to permit movement of the vehicle relative to an underlying surface in use of the land vehicle.

Various ridable karts for users are described. The ridable kart can include a kart body, a cover body, a rear caster wheel, a steering assembly, a battery, and a controller. The kart body can include an installation slot. The controller and the battery can be secured within the installation slot. The steering assembly can include a front wheel and a steering wheel. The front wheel can include a hub motor arrangement.
