Abstract: A sandwich plate element connection system (1, 2, 3, 4, 5), comprising two sandwich plate elements (100) and a connection element (200, 400, 500, 600, 700) connecting said two sandwich plate elements (100) by means of an adhesive joint (250) and defining two recesses (210, 220, 410, 420, 510, 520, 530, 610, 620, 630, 640). The connection element (200, 400, 500, 600, 700) comprises a first part (200:1, 400:1, 500:1, 600:1, 700:1) and a second part (200:2, 400:2, 500:2, 600:2, 700:2) connected to each other by a snap fit joint (270, 470, 570, 670, 770), for formation of at least one of said two recesses (210, 220, 410, 420, 510, 520, 530, 610, 620, 630, 640). The adhesive joint (250) comprises an adhesive (260). A chassis (10) for a vehicle comprising a sandwich plate element connection system (1, 2, 3, 4, 5) and a method (20) for connecting two sandwich plate elements (100) are also provided.

Abstract: The present invention relates to a chassis (10) for a vehicle comprising a plurality of sandwich plate elements (100) and a plurality of connection elements (200, 200?, 200a-c) for connecting said plurality of sandwich plate elements (100). Each connection element (200, 200?, 200a-c) comprises two or more recesses (210, 220) configured to receive an edge portion (160) of one of the plurality of sandwich plate elements (100). The plurality of connection elements (200, 200?, 200a-c) comprises at least one connection element (200?, 200a-c) which has at least one external surface (202a-e) provided with a connection configuration (250a-e) for a mortise and tenon type joint. A method (20) for forming a chassis (10) for a vehicle is also provided.

Abstract: 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).
