Abstract

A five-cell mechanism based on a magnetic composite spherical hinge, the mechanism comprising: identical first to fifth composite spherical hinges (1, 2, 3, 4, 5) and identical first to tenth telescopic rods ( 6, 7, 8, 9, 10, 11, 12, 13, 14, 15), forming a space five-cell mechanism. The mechanism can pass through the plane formed by the other three composite spherical hinges along the direction of any two composite spherical hinges to complete a traversing movement. It can provide elementary and middle school students with an understanding of geometric shapes and mobile mechanisms, and can be used to make institutional teaching aids and toys, and can also be used to make military detection robots.

Description

technical field [0001] The invention relates to a five-cell mechanism, specifically a composite spherical hinge based on magnetic connection, and a five-cell mechanism based on it. Background technique [0002] There are various forms of spherical joint structure, which are often used in the case where two members have three relative rotations. Because the relative motion is more complicated, it is necessary to realize the connection of multiple rods at the same point, and at the same time realize that each rod is connected to each other by a spherical hinge. Mechanical structure design is rare. The spatial link mechanism has a compact structure, utilizes its own structural deformation, and has various forms of movement. [0003] Chinese patent CN203035739U discloses a "spherical hinge assembly", which proposes a two-bar spherical hinge connection structure for automobile steering. The structural scheme is simple, and a dust cover with a rigid slot and a rigid fastening su...
