Abstract

L'invention concerne un panneau destiné à former une surface d'une structure tridimensionnelle, fabriquée par le couplage de billes métalliques avec des tiges magnétiques. Une structure de panneau destinée aux jouets magnétiques, selon la présente invention, comprend un panneau (100). Le panneau possède un corps du panneau circulaire ou orthogonal (110). Au moins un support de tige cylindrique (120) est ménagé sur chaque surface latérale du corps du panneau et s'étend horizontalement vers l'extérieur par rapport au corps du panneau. En outre, un trou d'insertion de tige (121) est foré dans le support de tige. La structure du panneau de cette invention permet de raccorder fermement le panneau et de fabriquer des modèles de formes différentes à partir d'un nombre limité de tiges et de billes métalliques, ce qui réduit le coût du produit et permet de créer de différents modèles en utilisant un nombre limité de tiges et de billes métalliques, ce qui a pour effet d'augmenter le potentiel créatif du produit.
