Description

Technical Field

[0001] This invention belongs to the field of plantar pressure distribution measurement technology, and more specifically relates to a modular splicing gait pressure analysis channel. Background Technology

[0002] Plantar pressure distribution measurement is a crucial component of quantitative gait analysis and a foundation for analyzing and measuring abnormal plantar pressure distribution and gait, playing a significant role in the objective analysis and evaluation of human motor balance function. Doctors can use plantar pressure distribution and other data to diagnose foot-related conditions such as flat feet, high arches, pronation, and supination. Compared to most existing wearable measurement systems, flat-panel channel-type measurement systems do not require any components worn on the subject's feet, offering no movement constraints. They are safer than wearable systems and do not require specially sized measuring components to improve accuracy, ensuring consistent measurement precision. Furthermore, they can measure the subject's movement trajectory, providing more comprehensive data. However, due to the subject's body type and movement posture, strict requirements must be placed on the channel length and installation method to ensure the accuracy and breadth of pressure distribution data measurement. Additionally, channel-type measurement systems are generally large and have complex internal wiring, impacting transportation, installation, and debugging. Therefore, providing a modular, spliced ​​gait pressure analysis channel is a problem urgently needing to be solved by those skilled in the art. Summary of the Invention

Users can adjust the number of measurement units to achieve different lengths of the dynamic measurement area, typically 4-6 meters, to address the issue of varying body shapes and movement postures of subjects, which may result in the dynamic measurement area length not meeting the test requirements.

[0026] The measuring unit includes a base shell 3 and multiple sets of pressure sensing modules arranged in a matrix. The mating side openings of the base shells 3 of adjacent measuring units are provided so that the outermost pressure sensing modules are tightly fitted, avoiding gaps on the mating side that could cause sensing gaps.

The three-dimensional force sensor 8 is disposed between the lower end of the force-bearing rod 6 and the bottom wall of the force-bearing groove 10. The upper end of the force-bearing rod 6 is embedded in the connecting groove 9 on the cover plate 4.

The three-dimensional force sensor 8 at the bottom is used to detect the triaxial pressure and summarize and analyze the data with the pressure sensors 7 located around the force-bearing rod 6 to improve data accuracy. The four sets of pressure sensors 7 and the one set of three-dimensional force sensors 8 are all electrically connected to the circuit board.

The female docking end is rotatably connected to the first docking groove 11. The male docking end is configured as multiple sets of connecting probes 13 evenly arranged along the second docking groove 12. The female docking end includes a rotating block 14. After rotating 180 degrees, one movable end of the rotating block 14 can be embedded in the second docking groove 12 to dock with the connecting probes 13.
