Description

Technical Field

[0001] This utility model relates to daily necessities, specifically to a foot pressure health monitoring device. Background Technology

[0002] Walking, as one of the most basic and frequent daily activities for humans, has gait characteristics and foot pressure distribution that are directly related to human health. Under normal circumstances, even foot pressure distribution maintains gait stability and balance; abnormal distribution can easily lead to gait instability, foot pain, and even long-term injuries (such as plantar fasciitis and collapsed arches), severely impacting quality of life. Therefore, real-time monitoring of foot pressure and analysis of gait characteristics are of great significance for preventing foot diseases and improving exercise health. In recent years, the development of smart wearable technology has driven research into foot pressure monitoring systems. Existing technologies are mainly focused on the medical field. However, existing technologies have the following limitations:

[0003] 1. Limited application scenarios: Existing systems are mostly designed for medical scenarios and lack life-related functions (such as daily gait correction and exercise suggestions), making it difficult to meet the needs of ordinary users.

[0004] 2. Insufficient data integration: Most solutions focus only on a single function (such as stress collection or gait classification) and do not combine real-time data transmission, user interaction and multi-dimensional health analysis.

[0005] 3. Insufficient comfort and practicality: The complex sensor layout or large device size results in poor comfort during long-term wear, affecting the user experience.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing pressure detection structures. Utility Model Content

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0030] Reference Figure 1-5 As shown, this utility model provides a foot pressure health monitoring device, which includes a detachably connected flat shoe 100 and a data collection base 200.

[0031] Flat shoes 100

[0032] The flat shoe 100 is equipped with a soft insole 101 and an upper 102. Nine thin-film pressure sensors are embedded in the inner side of the soft insole and the upper, distributed in key pressure areas of the foot. The sensors are only 0.1-0.3mm thick, ensuring no foreign body sensation when wearing them.

[0033] The nine thin-film pressure sensors are mainly distributed in five areas, as follows:

[0034] 1) Two pairs of plantar pressure sensors are installed in the forefoot area, namely the first plantar pressure sensor 111, the second plantar pressure sensor 112, the third plantar pressure sensor 113, and the fourth plantar pressure sensor 114. When walking, the first two pairs of sensors can capture the pressure peak during the toe push-off phase (i.e., the toe-off phase) to help determine whether the gait relies too much on the forefoot.

[0035] 2) The fifth plantar pressure sensor 115, located in the plantar arch area, is used to monitor the arch support force.

[0036] 3) The sixth plantar pressure sensor 116, located in the heel area, mainly collects the impact force when the heel strikes the ground, and can analyze whether there is "excessive heel pronation" or "impact gait" during walking.

[0037] 4) An instep pressure sensor 117 is provided on the inside of the shoe upper 102 to monitor the pressure on the instep.

[0038] 5) The first foot side pressure sensor 118 and the second foot side pressure sensor 119, which are in contact with the left and right sides of the foot on the inner side of the shoe upper 102, are used to detect the lateral force balance of the foot, such as to determine whether there is a tendency for flat feet or high arches.

[0039] A data export connector 120 is connected to the heel of the flat shoe 100. The data export connector 120 is fixed to the heel of the shoe via a silicone curved plate 121. The silicone curved plate 121 is fitted and fixed to the outer curved surface of the heel of the shoe upper 102. The data export connector 120 is fixed to the top rear end of the silicone curved plate 121. Signal lines for connecting the data export connector 120 and nine pressure sensors are provided inside the silicone curved plate 121.

[0040] Data collection base 200

[0041] The data collection base 200 is equipped with a data receiving plug, which includes a housing connection part 201, a first housing side plate 202, a housing rear plate 203, a second housing side plate 204, and a housing bottom plate 205. The front end of the housing connection part 201 has a protruding PIN interface 206 that connects to the data output connector 120. The first housing side plate 202, the second housing side plate 204, the housing rear plate 203, and the housing bottom plate 205 are all connected to the rear end of the housing connection part 201 to form a closed battery compartment at the rear end of the housing connection part 201. A battery 207 and a signal conditioning circuit board 210 are installed in the battery compartment. The battery 207 and the signal conditioning circuit board 210 are connected, and the signal conditioning circuit board 210 is connected to the PIN interface 206.

[0042] The signal conditioning circuit board 210 includes a buzzer 216, an operational signal amplifier 211, an A / D conversion module 212, a microcontroller 213, a main control chip 214, and a WiFi communication module 215. The operational signal amplifier 211 is connected to the microcontroller 213 via the A / D conversion module 212. The microcontroller 213, the WiFi communication module 215, and the buzzer 216 are all connected to the main control chip 214. In an optional embodiment, the signal conditioning circuit board 210 is an ESP32 circuit board.

[0043] In use, the data collection base 200 is plugged into the data export connector 120 at the heel of the flat shoe 100. The user walks barefoot in the flat shoe 100, and the nine thin-film pressure sensors embedded in the shoe synchronously collect pressure signals from various areas of the foot.

[0044] like Figure 5 As shown, each thin-film pressure sensor is based on the piezoresistive effect, and its resistance value changes linearly with pressure. The pressure signal is amplified by an operational amplifier to eliminate environmental noise interference; the A / D conversion module 212 converts the analog voltage signal into a digital signal; the microcontroller 213 encapsulates the data from the nine sensors into frame data packets according to timestamps and transmits them to the main control chip 214 through the interface. The main control chip 214 uses a sliding window mean filter to eliminate instantaneous interference, maps the original voltage value to a pressure percentage, and finally transmits the data to the mobile terminal via the WiFi communication module 215. The mobile terminal processes the data. If the mobile terminal detects a risk of falling, it sends a signal to the main control chip 214 through the WiFi communication module 215, and the main control chip 214 activates a buzzer to sound an alarm.

[0045] It should be noted that all circuit modules of the signal conditioning circuit board 210 are existing technologies, and the way each module processes signals is also a common technique used by those skilled in the art. Furthermore, the mobile terminal processes the received data and determines whether there is a risk of falling, which can be easily achieved through mature cloud algorithms and is also a common technique used by those skilled in the art. This is not within the protection scope of this utility model and will not be elaborated here.

[0046] The rear panel 203 of the mounting box has a wiring hole 2031. The power cord passes through the wiring hole 2031 and connects to the battery to supply power to the battery 207. Preferably, the power cord has a Type-C interface on one end outside the wiring hole 2031 for easy connection to an external charger.

[0047] The preferred embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above. Devices and structures not described in detail herein should be understood as being implemented in a conventional manner within the art. Any person skilled in the art can make many possible variations and modifications to the technical solutions of this utility model using the disclosed methods and techniques, or modify them into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. This does not affect the essential content of this utility model. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the content of the technical solution of this utility model, still fall within the protection scope of the technical solution of this utility model.
