Paper folding type wheel with variable width

Abstract

The invention relates to a paper folding type wheel with the variable width. The paper folding type wheel comprises a reducing wheel carrier and a wheel shaft installed on the reducing wheel carrier.The reducing wheel carrier comprises a plurality of folding units sequentially connected end to end to form a ring. Each folding unit is provided with a first plane, a second plane, a third plane, a fourth plane, a fifth plane and a sixth plane; a first valley fold line is arranged between the first plane and the second plane and is symmetrically arranged by taking the first valley fold line as acenter; a first mountain fold line is arranged between the third plane and the fourth plane and is symmetrically arranged by taking the first mountain fold line as the center; a second valley fold line is arranged between the first plane and the third plane, a third valley fold line is arranged between the second plane and the fourth plane, the fifth plane and the sixth plane are symmetrically arranged with the first valley fold line as the center, and the fifth plane and the sixth plane are connected with the first plane and the second plane respectively. The paper folding type wheel with thevariable width can adjust the width of the variable-diameter wheel carrier, and belongs to the technical field of variable-width wheels and variable-diameter wheels.

Description

technical field [0001] The invention relates to the technical field of variable-diameter wheels, in particular to a variable-width origami wheel. Background technique [0002] On uneven roads in disaster areas, narrow gaps in caves or unknown complex road environments, higher requirements are placed on the adaptability and passability of wheels. At present, domestic studies on rigid variable-diameter wheels have begun, such as a variable-diameter wheel that automatically adapts to the road surface. This type of rigid variable-diameter wheel is assembled by a certain number of parts. It can run freely on uneven and complex road surfaces. However, the internal structure of the rigid variable diameter wheel is complicated, the assembly process is cumbersome, the manufacturing precision of the parts is high, and the deformation method is single, so the deformation of the wheel width cannot be realized. In recent years, several types of deformable origami wheels have appeared a...

However, the internal structure of the rigid variable diameter wheel is complicated, the assembly process is cumbersome, the manufacturing precision of the parts is high, and the deformation method is single, so the deformation of the wheel width cannot be realized.

In recent years, several types of deformable origami wheels have appeared abroad, but these types of wheels can only achieve the deformation of the wheel diameter, and also fail to achieve the deformation of the wheel width, and cannot guarantee the adaptability and passability of the wheels to unknown narrow and complex road surfaces. still not practical
