Foot board device for measuring foot applied force

Abstract

The invention aims to disclose a foot board device for measuring foot applied force. According to the device, each foot part comprises an upper layer and a lower layer, four foot boards including two front boards and two back boards, miniature pressure sensors, a butterfly hinge, articulation hole screw rods, a foot board frame, a back extending frame, a front bandage and a back bandage, and a data acquisition module, wherein necessary foot applied force data can be obtained through the pressure sensors and the data acquisition module mounted between the two layers of front sole boards and back sole boards; horizontal displacements of the two layers of upper boards and lower boards are limited with the help of the articulation hole screw rods; the position of a sole is limited with the help of the foot board frame; the size of the sole is adapted with the help of the adjustment of the back extending frame; and an instep is tied by the front bandage and the back bandage. The device is simple in structure, high in durability, convenient to measure, and low in cost, not only can be used alone to measure the distribution of the foot applied force in a human static state, but also can be used in conjunction with a gait rehabilitation training robot, a wearable power assist robot, an exoskeleton lower extremity rehabilitation robot and the like in conventional to measure the foot applied force of a user in walking state.

Description

technical field [0001] The utility model relates to a pedal device for detecting plantar force, which belongs to the fields of biomedical engineering and rehabilitation medicine. Background technique [0002] At present, the incidence of bone marrow injury, stroke, Parkinson's disease and other lesions is on the rise, causing more and more patients with lower limb motor dysfunction, which greatly affects the quality of life of patients. Objective and accurate gait analysis can evaluate the walking function of patients, understand the degree and characteristics of their dysfunction, and guide treatment and rehabilitation training in time. The change of plantar pressure during walking has an important impact on the forces and moments acting on the joints of the lower limbs. Gait research based on plantar pressure is an important part of quantitative gait analysis. The distribution of plantar pressure can reflect the structure and function of the foot and the control of the wh...

Problems solved by technology

These achievements have their own advantages, but they are generally expensive, and the key technology has not been disclosed; the force plate and the force plate are large in size, and cannot be well integrated with the existing pedal-type gait rehabilitation robots, wearable power-assisted robots, Exoskeleton-type lower limb rehabilitation robots are used together; although pressure insoles are easy to operate and can be used in conjunction with rehabilitation robots, due to the soft base and limited life, their own deformation may cause measurement errors
