Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a shoe for monitoring gait, including a sole 1, an upper 2 connected to the upper part of the sole 1, an insole 3 filled in the space enclosed by the sole 1 and the upper 2, an inner support block 4 fixedly connected inside the sole 1, a power supply module 5 installed in the middle of the inner support block 4, and a first pressure sensor 6 and a second pressure sensor 7 respectively connected to the two sides of the inner support block 4. The first pressure sensor 6 corresponds to the ball of the foot, and the second pressure sensor 7 corresponds to the heel. Both the first pressure sensor 6 and the second pressure sensor 7 are used to collect data, which can sense the pressure change when the foot hits the ground, obtain the pressure peak and pressure distribution, thereby monitoring the user's gait;

[0019] The inner support block 4 has a first groove 41, a second groove 42 and a third groove 43 respectively. A wire groove 44 is reserved between the first groove 41 and the second groove 42 and between the first groove 41 and the third groove 43. The wire groove 44 can be used to arrange the cables connected to the circuit board 54, the first pressure sensor 6 and the second pressure sensor 7.

[0020] The first pressure sensor 6 and the second pressure sensor 7 are both fixed inside the second tank 42 and the third tank 43 by adhesive layer 8, and the adhesive layer 8 is 3M adhesive.

[0021] The first groove 41 is equipped with an outer cover frame 9. The outer cover frame 9 is a hollow structure with an opening facing downwards, which can cover the outside of the power supply module 5. Correspondingly, wire holes 91 with the same function as wire groove 44 are opened on both sides of the outer cover frame 9. The function of the outer cover frame 9 is to support the arch of the foot and prevent the user from damaging the power supply module 5 due to their own weight when walking. The upper surface of the outer cover frame 9 is adapted to the upper surfaces of the first pressure sensor 6 and the second pressure sensor 7, so that it can provide sufficient support after the insole 3 is filled.

[0022] The power supply module 5 includes a base plate 51 installed inside the first slot 41. A wireless charging coil 52 and a circuit board 54 are respectively installed on the upper part of the base plate 51. A battery 53 is connected to the upper part of the circuit board 54.

[0023] The charging end of battery 53 is connected to the power transmission end of wireless charging coil 52 via a wire. After the shoe is placed on the external wireless charging stand, the wireless charging stand will wirelessly charge battery 53 after it aligns with the wireless charging coil 52. This is a known technology and will not be described in detail here.

[0024] In addition, the circuit board 54 has a built-in Bluetooth or WIFI module, which can connect to the user's mobile phone and upload gait data. The user can view their gait through the corresponding APP built into the mobile phone, thereby understanding their walking situation.

[0025] Specifically, the upper 2 is fixed to the upper edge of the sole 1 by stitching or adhesive to form a closed space to accommodate the insole 3. An inner support block 4, pre-molded inside the sole 1, is made of a high-strength polymer (such as nylon + glass fiber composite material) to ensure it does not deform under stress.

[0026] A first groove 41 is formed in the middle of the inner support block 4, and a second groove 42 and a third groove 43 are symmetrically machined on both sides. A wire groove 44 with a width of 2mm and a depth of 1.5mm is reserved between the grooves, and the surface is covered with an anti-slip silicone sleeve (not shown in the figure) to prevent cable wear;

[0027] The first pressure sensor 6 and the second pressure sensor 7 are placed in the second tank 42 and the third tank 43, respectively. The sensor surface is coated with a 3M adhesive layer 8 with a thickness of 0.3mm, and the bonding is completed by irradiation with a UV curing device for 10 seconds to ensure that the sensor can withstand a vertical pressure of more than 100kg without falling off.

[0028] A flexible flat cable (FFC) is used, which is led from the sensor welding end along the cable groove 44 to the first groove 41. The cable has an arc transition (bending radius ≥3mm) at the corner of the groove, and is covered with heat shrink tubing for enhanced protection. A waterproof sealing ring is installed at the cable hole 91 of the outer frame 9 to achieve an IP67 protection rating;

[0029] The base plate 51 is fixed to the bottom of the first slot 41 with M2 screws. The wireless charging coil 52 (outer diameter 40mm, thickness 0.8mm, supporting Qi protocol), circuit board 54 (integrated STM32F411 microcontroller), and battery 53 (polymer lithium battery, capacity 800mAh) are then installed sequentially. Electrical connections between the components are achieved using conductive silver paste to reduce contact resistance.

[0030] The external charging dock has a built-in transmitting coil. When the distance between the shoe sole 1 and the charging dock is ≤5mm, the wireless charging coil 52 receives the alternating magnetic field and charges the battery 53 through the rectifier circuit. The charging efficiency is ≥75%, and the full charge time is approximately 2 hours (5V / 2A input).

[0031] Circuit board 54 integrates a Bluetooth 5.0 module (model CC2541) and a WIFI chip (ESP8266), and configures the SSID and password via AT command set. The data sampling frequency is set to 100Hz, and the pressure data is packetized and transmitted after Kalman filtering, with each packet ≤20 bytes.

[0032] Users install the accompanying app on their mobile phones (supports iOS / Android) and scan the QR code on the shoe sole to complete pairing upon first use. The app interface displays a real-time gait waveform (X-axis time, Y-axis pressure value), providing gait cycle analysis (support phase / swing phase duration), center of pressure trajectory (CoP), and abnormal gait warnings (such as left and right foot pressure imbalance exceeding 30%). Historical data can be exported in CSV format for professional analysis.
