Embodiment 1

[0043] A cushioning and shock absorbing structure based on the origami principle, such as Figure 1-9 As shown, it includes an upper load-bearing plate 1, a deformation energy-absorbing module, and a base 2. The deformation energy-absorbing module is arranged between the upper load-bearing plate 1 and the base 2. The deformation energy-absorbing module includes three such as The basic module 3 is placed in a triangle with a flexible origami structure.

[0044] In this embodiment, the basic module 3 can be a flexible origami structure of various shapes, and the shock absorption and buffering effect can be realized by the flexible origami structure.

Embodiment 2

[0046]On the basis of embodiment 1, this embodiment is improved as:

[0047] like Figure 1-9 As shown, the basic module 3 includes 3 fastening and positioning frames 31, 2 deformation energy absorbing films 33, and each deformation energy absorbing film 33 is provided with 8 stability-enhancing and limiting panels 32; The frames 31 are arranged in the up-down direction, and the two deformable energy-absorbing films 33 are formed by origami process to form a buffering and shock-absorbing cylinder with open upper and lower ends. The upper and lower ends of the buffering and shock-absorbing cylinders are respectively fixedly connected to the ends of the corresponding fastening and positioning frames 31 , and the stability-enhancing and limiting panels 32 are fixedly connected to the surface of the deformation energy-absorbing film 33 .

[0048] In this embodiment, the fastening and positioning frame 31 can be set in a square, circular or other shape as required, the buffer and ...

Embodiment 3

[0050] On the basis of embodiment 2, this embodiment is improved as:

[0051] like Figure 1-9 As shown in the figure, the fastening and positioning frame 31 is a regular quadrilateral frame, the deformation energy absorbing film 33 is a parallelogram structure, and the manufacturing method of the buffering and shock absorbing cylinder is: Step A1, the parallelogram structure 2 Each long side is divided into 4 equal parts, and grooves are cut in the inner surface of the deformation energy absorbing film 33 along the connection line of the upper and lower corresponding bisected points, and three first grooves 333 parallel to the sides of the parallelogram structure are formed. At the same time, the parallelogram structure is divided into four smaller parallelogram structures by the first groove 333; in step A2, the outer surface of the deformation energy absorbing film 33 moves along the longer diagonal of the smaller parallelogram structure to dig grooves , and form 4 second ...

Abstract

A buffering and damping structure based on a paper folding principle relates to the technical field of buffering and damping devices, and comprises an upper bearing plate, a deformation energy-absorbing module and a base, the deformation energy-absorbing module is arranged between the upper bearing plate and the base, the deformation energy-absorbing module comprises three basic modules placed in an equilateral triangle shape, the basic module is of a flexible paper folding structure, the top end of the basic module is fixedly connected with the lower surface of the upper bearing plate, and the bottom end of the basic module is fixedly connected with the upper surface of the base. According to the buffering and damping structure based on the paper folding principle, the problems that a traditional buffering device is poor in adaptability, low in space utilization rate, difficult to install and move and the like are solved, and the buffering and damping structure has practical and wide application in the aspects of precise instrument buffering, human skeleton protection and the like.

Description

technical field [0001] The invention relates to the technical field of buffering and shock-absorbing devices, in particular to a buffering and shock-absorbing structure based on the origami principle. Background technique [0002] With the advent of the era of intelligence, more and more precision instruments are applied to the field of industrial production. In the process of transportation and use of precision instruments, providing a reliable buffer and shock absorption device can ensure that precision instruments are not damaged and effectively Guaranteed accuracy during use. The existing buffer and shock absorption structures are divided into the following categories: [0003] 1. Spring shock absorber [0004] The spring shock absorber is the most common buffer shock absorber in existence. It can achieve the effect of buffer shock through the deformation of the spring, and can well control the torsional vibration. However, it can only play the effect of buffering and...
