This paper presents a new method for constructing a novel thick-panel origami cube. By replacing the equivalent 4R-spherical linkage in a four-crease zero-thickness origami vertex with a plane-symmetric Bricard linkage, the thick-panel form of a general plane-symmetric four-crease origami vertex is identified and constructed. The proposed thick-panel vertex preserves the kinematics of the original four-crease origami vertex. Then, by utilizing the proposed thick-panel vertex, a thick-panel cube is constructed based on the zero-thickness origami cube that was proposed in our previous work. Through mechanism decomposition, geometric constraints and kinematic properties of the corresponding integrated mechanism are investigated and formulated, which reveals the kinematic equivalence between the thick-panel and zero-thickness forms of the origami cube. In addition, a prototype of the proposed thick-panel origami cube is fabricated, verifying its kinematic properties. The proposed technique can be extended to the design and construction of thick-panel polyhedrons with potential applications in the fields such as aerospace exploration, robotics and architecture.

本文提出了一种构建新型厚板折纸立方体的新方法。通过替换等效的 4 R-四折零厚度折纸顶点中的球形连杆与平面对称布里卡德连杆，确定并构造了一般平面对称四折折纸顶点的厚面板形式。提议的厚板顶点保留了原始四折折纸顶点的运动学。然后，利用提出的厚板顶点，基于我们之前工作中提出的零厚度折纸立方体构造了厚板立方体。通过机构分解，研究并制定了相应集成机构的几何约束和运动学特性，揭示了折纸立方体的厚板形式和零厚度形式之间的运动学等效性。此外，还制作了所提出的厚板折纸立方体的原型，验证其运动学特性。所提出的技术可以扩展到厚板多面体的设计和构建，在航空航天探索、机器人和建筑等领域具有潜在应用。
