Flat-spread large three-dimensional scene display type three-dimensional book

Abstract

The invention discloses a flat-spread large three-dimensional scene display type three-dimensional book which comprises a bottom plate and a folding body, wherein the bottom plate can be folded along the center line of the bottom plate; the folding body is bonded on the bottom plate and can be folded along the center line of the bottom plate, the folding body comprises a multi-layer folding structure and a vertical structure, a V-shaped knife edge is formed in the bottom plate, the two side edges of the multi-layer folding structure are connected with the V-shaped knife edge, and the bottom edge of the vertical structure is bonded on the two sides of the bottom plate along the center line of the bottom plate; the multi-layer folding structure is folded forwards and backwards in sequence in the direction parallel to a symmetry axis with the center line of the multi-layer folding structure as the symmetry axis. The multi-layer folding structure is adopted, so that the extension range is larger when a book is opened, a larger area is provided for containing more vertical structures; and more importantly, the extension structures can be smoothly retracted into the book when the book is closed, and the interestingness, attraction and sensory enjoyment of the paper type book are improved.

Description

technical field [0001] The invention relates to a cultural utensil, in particular to a three-dimensional book with a large three-dimensional scene display. Background technique [0002] Books are the carrier of knowledge, and its invention has played a certain role in the dissemination of knowledge. Since Cai Lun invented paper, paper-shaped books have played an extremely important role in the dissemination of knowledge. In the process of development, there have been many kinds of paper-shaped books However, the basic structure and shape of the book have not changed much. They are all based on the two-dimensional form of the paper page. The form is relatively simple and only serves as a carrier. [0003] With the rapid development of society, e-books have gradually penetrated into our lives, but reading e-books cannot bring people sensory enjoyment, and they cannot feel the satisfaction brought by flipping paper, so there is still a large market for paper books space. As p...

Problems solved by technology

[0004] In the existing three-dimensional book, there is a problem that the pages can be unfolded backwards when they are opened, but they cannot be retracted autonomously. Manual assistance is required to retrieve them and they are easy to break. The purpose of the present invention is to enable the backward expanded parts to be retracted smoothly and autonomously when closed.
