The present disclosure relates to the technical field of human body data information collection, in particular to a rigidity-adjustable plantar pressure measuring device.
In modern medical rehabilitation auxiliary treatment, human gait information is one of the important bases for doctors to determine patients' rehabilitation. Detecting plantar pressure is an important part of gait analysis, and is the basis for analyzing abnormal plantar stress distribution and gait.
The traditional plantar pressure measurement is performed mainly by a pressure test plate or a plantar pressure test shoe (pad). The test system of the pressure test plate is limited to special shoes or measuring bare feet, which is not wearable and has greater limitations. Compared with the pressure test plate, the pressure test shoe (pad) is more flexible, and is not limited by the range of motion and location, but it is prone to slip largely during the detection process, which affects the detection accuracy; and the pressure test shoe cannot be adapted according to different sizes of the soles, which also has certain limitations
The present disclosure aims to provide a rigidity-adjustable plantar pressure measuring device to solve the problems that the existing plantar pressure measuring device is largely limited in application and is poor in detection accuracy.
In order to solve the above problems, the present disclosure provides a rigidity-adjustable plantar pressure measuring device sleeved on a shoe body. The device includes a shoe cover body and a data processing communication unit, where the shoe cover body includes a toe pressure detection part, a sole pressure detection part and a heel pressure detection part. A front end of the toe pressure detection part is provided with a first limit structure for containing and limiting a front end of the shoe body, a rear end of the toe pressure detection part is connected with a front end of the sole pressure detection part, and a plurality of first pressure detection components are installed on the toe pressure detection part. A rear end of the sole pressure detection part is connected with a front end of the heel pressure detection part through a retractable component, and a plurality of second pressure detection components are installed on the sole pressure detection part. A rear end of the heel pressure detection part is provided with a second limit structure for abutting against a rear end of the shoe body, and a plurality of third pressure detection components are installed on the heel pressure detection part.

Main bodies of the toe pressure detection part 110, the sole pressure detection part 120, and the heel pressure detection part 130 can be of a plate-like structure, as shown in figures. In this embodiment, a front end of the toe pressure detection part 110 is provided with a first limit structure 111 for containing and limiting a front end of the shoe body. A rear end of the toe pressure detection component 110 is connected with a front end of the sole pressure detection part 120, and a plurality of first pressure detection components 112 are installed on the toe pressure detection part 110.
