Bionic walking stick supporting foot pad

Abstract

The invention relates to a walking stick assisting a user to walk, in particular to a bionic walking stick supporting foot pad. The bionic walking stick supporting foot pad in the bionic field comprises a grounding area and an inlaying area. The grounding area is of a bionic locust foot sole stereo structure, and the inlaying area is of a hollow cylindrical structure. By utilizing the physical characteristics of the simulated locust foot sole of the grounding area, the adhesive force to the ground of the bionic walking stick supporting foot pad is increased, and anti-slipping effect is improved. The anti-slipping performance of the bionic walking stick is improved based on a bionic design concept, a bionic locust supporting foot pad is added at the grounding end of the walking stick, and the special structure of the locust foot sole facilitates reduction of contact rigidity, increase of contact area and production of adhesion friction force enabling the foot sole to be stable in the contact process. Based on geometrical morphology of the surface of the locust foot sole and functional characteristics of flexor tendon of the locust foot sole, the bionic walking stick supporting foot pad simulating the locust foot sole plays a good anti-slipping effect.

Description

technical field [0001] The patent of the present invention relates to a crutch for helping people to walk, in particular to a bionic crutch pad. Background technique [0002] The parts of the crutches that help people walk in contact with the ground are called foot pads. On the one hand, the material of the foot pad has a large friction coefficient, which can prevent the crutches from slipping when in contact with the ground; on the other hand, the material of the foot pad has good elasticity, which can buffer the impact caused by the ground reaction force, thereby reducing people's discomfort. Since the foot pad needs to meet the requirements of the above two aspects, it often adopts a rubber material that should have both a large friction coefficient and high elasticity, but such a material is inevitably low in strength. The wear resistance is poor, resulting in short life of the foot pads and easy damage. Therefore, its anti-slip and wear resistance can be improved by d...

AI Technical Summary

Problems solved by technology

[0003] Due to the limitations of the structural design, the common crutch pads are not very comfortable when used, and the anti-skid effect is not good. Only when the crutches are used vertically to the ground can they provide better adhesion; and during use, the wear of the pads is not good. Uniform, it is easy to have the problem that the edge of the foot pad wears first, thus affecting its service life

The bottom of the foot pads in the prior art is usually arc-shaped or flat. In actual use, because the ground contact area is small, the contact pressure distribution between the foot pad and the road surface is unreasonable, resulting in the foot pad being easily worn. , so the anti-skid effect is not very good
