The invention provides a plate spring body, a mold for preparing the plate spring body and a plate spring assembly, the plate spring body is provided with a parabolic structure, the convex surface of the parabolic structure is the upper surface of the plate spring body, and the concave surface of the parabolic structure is the lower surface of the plate spring body; a step structure is formed between the side surface and the upper surface of the parabolic structure; wherein the step structure comprises a first vertical surface perpendicular to the upper surface and a first plane perpendicular to the first vertical surface, and a first connection surface is formed between the upper surface and the first vertical surface. In the embodiment of the invention, through the design of the step structure and the first connecting surface, the mechanical property of the plate spring body can be improved on the basis of reducing the research and development cost and the manufacturing cost of a mold for preparing the plate spring body.

    本申请提供了一种板簧本体、用于制备板簧本体的模具和板簧总成,该板簧本体具有抛物线型结构,该抛物线型结构的凸面为板簧本体的上表面,该抛物线型结构的凹面为板簧本体的下表面;该抛物线型结构的侧表面和该上表面之间形成有台阶结构;其中,该台阶结构包括与该上表面垂直的第一竖直面和与该第一竖直面垂直的第一平面,该上表面和该第一竖直面之间形成有第一衔接表面。本申请实施例中,该台阶结构和第一衔接表面的设计,能够在降低用于制备板簧本体的模具的研发成本以及制造成本的基础上,提升板簧本体的力学性能。
