Embodiment Construction

[0026] The present invention is further described below in conjunction with accompanying drawing:

[0027] see Figure 1 to Figure 6 , a soft mechanical foot, including the heel, arch and forefoot; the arch of the foot is in the middle, and the heel and forefoot are separated on both sides of the arch;

[0028] The heel includes several rigid supports and heel flexible plates 18; several rigid supports are vertically and fixedly arranged on the surface of the heel flexible plate 18 at equal intervals, and the length of several rigid supports gradually increases or decreases in the length direction of the heel flexible plate 18;

[0029] The forefoot includes several forefoot rigid supports and forefoot flexible plates 20; several forefoot rigid supports are vertically fixed on the surface of the forefoot flexible plate 20 at equal intervals, and the length of several forefoot rigid supports gradually increases in the length direction of the forefoot flexible plate 20 or reduc...

Abstract

The invention discloses a compliant mechanical foot which at least comprises a heel, a foot arch and a forefoot, wherein the heel, the foot arch and the forefoot are sequentially connected into a toothed asymmetric trapezoidal structure through flexible pieces, the foot arch is centered, and the heel and the forefoot are arranged on the two sides of the foot arch correspondingly. The compliant mechanical foot has the characteristics of simple structure, small number of parts, low manufacturing cost, reliable use, easy assembly, easy expansion, good vibration damping, impact resistance, no friction in the movement process, high in movement stability and the like.

Description

technical field [0001] The invention belongs to the field of compliant mechanisms, in particular to a compliant mechanical foot. Background technique [0002] With the development of flexible mechanisms and rigid mechanisms, rigid-flexible and variable stiffness mechanisms are becoming more and more common, especially widely used in some mechanisms that require great flexibility, perfectly combining the advantages of flexible mechanisms with traditional rigid mechanisms , to achieve the effect that one plus one is greater than two. Push institutional science to a new level. [0003] With the development of robot technology, humanoid robots and walking robots are becoming more and more common. To a certain extent, its foot mechanism determines the stability, adaptability and other performances of the robot. The feet of traditional robots are mostly made of elastic materials such as rubber wrapped around the rigid mechanism, which will cause disadvantages such as easy wear ...
