[0023] The following will describe a motion sensing device and sports shoes having the motion sensing device according to embodiments of the present invention with reference to the relevant drawings, wherein the same elements will be described with the same reference numerals.

[0024] The sports shoes of the present invention are a type of footwear that can be worn by athletes for walking or exercising, such as but not limited to sports shoes (such as badminton shoes, basketball shoes, baseball shoes, football shoes, golf shoes) or jogging shoes. The motion sensing device can be installed on the sports shoes to sense the athlete's walking or exercising status. At the same time, it also has the characteristics of being lightweight, easy to disassemble, and affordable.

[0025] The sports shoes in the following embodiments are taken as badminton shoes, but are not limited to badminton shoes.

[0026] Figure 1A and Figure 1B They are schematic diagrams of sports shoes from different perspectives according to an embodiment of the present invention, Figure 2A This is a functional block diagram of a motion sensing device according to an embodiment of the present invention. Figure 2B This is a schematic diagram of a motion sensing device according to an embodiment of the present invention. Figure 3 for Figure 2B The exploded diagram of the inertial sensing module of the motion sensing device is shown in FIG. Figure 4 for Figure 1A Schematic diagram of the structure of the insole and foot pressure sensing components in sports shoes. Figure 1B In order to clearly illustrate the location of the foot pressure sensing component 11, Figure 1B The insole 24 located on the foot pressure sensing assembly 11 is not shown (installed).

[0027] Please refer to Figures 1A to 4 The sports shoe 2 of the present invention comprises a shoe body 21, an insole 22 ( Figure 1B )、Tongue 23、Insole 24( Figure 1A ), shoelaces 25 and motion sensing device 1.

[0028] The shoe body 21 includes an upper 211, through which a shoelace 25 passes through a plurality of eyelets 26. The upper 211 refers to the front surface of the shoe body 21 facing the toes, including the area where the shoelaces 25 are fastened, but excludes the side panels 212 on the left and right sides of the shoe body 21. The shoe body 21, upper 211, side panels 212, insole 22, tongue 23, insole 24, shoelace 25, eyelets 26, and other components of the shoe 2 are common to all sports shoes. Their relative relationships, functions, and locations are well known and will not be further described here.

[0029] The motion sensing device 1 is mounted on a sports shoe 2 and may include a foot pressure sensing component 11 and an inertia sensing module 12. Figure 1B and Figure 4As shown, the foot pressure sensing assembly 11 of this embodiment is disposed on the insole 22 of the sports shoe 2 and is located between the insole 24 and the insole 22. Therefore, installation is very convenient by first removing the insole 24, then installing the foot pressure sensing assembly 11 into the insole 22, and then inserting the insole 24.

[0030] like Figure 2B As shown, the foot pressure sensing assembly 11 includes a plurality of pressure sensing pads 111 and a soft board 112. The soft board 112 can be a flexible circuit substrate, and the pressure sensing pads 111 are disposed on the soft board 112 to sense the pressure on the sole of the foot of an athlete wearing the sports shoe 2 while exercising (including walking), thereby outputting a foot pressure signal PS. In this embodiment, the shape and size of the soft board 112 are substantially the same as the insole 24. There are eight pressure sensing pads 111 in total, of which three are disposed on the front side of the soft board 112 to sense pressure on the toes, two are disposed on one side of the soft board 112 to sense pressure on the outside of the sole, and three are disposed on the back side of the soft board 112 to sense pressure on the heel.

[0031] The pressure sensing pad 111 can be made of a polymer pressure-sensitive material, and its initial resistance value can be, for example, greater than 10MΩ. The greater the pressure on the pressure sensing pad 111, the smaller its resistance value, and vice versa. By analyzing the changes in the resistance value of each pressure sensing pad 111 caused by pressure at different locations on the sole of the foot, the sole pressure at each location can be determined. The number of pressure sensing pads 111 and their configuration positions in this embodiment are only examples and are not limited thereto. In different embodiments, the number and configuration positions of the pressure sensing pads 111 can be adjusted according to the motion state and data analysis requirements.

[0032] The flexible board 112 of this embodiment includes an extension 1121 on its side. The extension 1121 corresponds to the outside of the sole of the foot, and the foot pressure sensing assembly 11 is (electrically) connected to the inertial sensing module 12 via the extension 1121. Furthermore, the foot pressure sensing assembly 11 of this embodiment may further include a plurality of wires 113 disposed on the flexible board 112. These wires 113 connect to the pressure sensing pads 111 and extend along the extension 1121 to electrically connect to the inertial sensing module 12, thereby transmitting the foot pressure signals PS generated by the pressure sensing pads 111.

[0033] The inertial sensing module 12 is electrically connected to the pressure sensing pads 111. Figure 1AAs shown, the inertial sensing module 12 of this embodiment is fixed to the upper 211 of the athletic shoe 2 and located on the tongue 23 and shoelace 25. It is worth noting that, in this disclosure, any area located on the front of the athletic shoe 2, including the shoelace 25 and tongue 23, is referred to as being located on the upper 211 of the athletic shoe 2. Furthermore, compared to fixing the inertial sensing module 12 to the side 212 of the athletic shoe 2, this embodiment fixes the inertial sensing module 12 to the upper 211 of the athletic shoe 2 and locates it on the tongue 23, resulting in higher and more accurate sensing accuracy, which in turn leads to more accurate subsequent data analysis. The details of how to fix the inertial sensing module 12 to the tongue 23 are explained below.

[0034] like Figure 2A and Figure 2B As shown, the inertial sensing module 12 of this embodiment may include an inertial sensor 121 and a wireless communication unit 122. The inertial sensor 121 may sense the motion of the athlete's foot while wearing the sports shoe 2 and output an inertial signal IS. The wireless communication unit 122 wirelessly transmits the foot pressure signal PS output by the foot pressure sensing assembly 11 and the inertial signal IS output by the inertial sensor 121. In this embodiment, the foot pressure signal PS output by the pressure sensing pad 111 may be transmitted to the inertial sensing module 12 and then wirelessly transmitted via the wireless communication unit 122.

[0035] In one embodiment, the inertial sensor 121 includes, for example but not limited to, a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer, thereby sensing the inertial signal IS generated when an athlete wears the sneakers 2 while exercising. Therefore, the inertial signal IS may include acceleration signals, angular velocity signals, magnetic signals, or a combination thereof, generated during the athlete's foot movement. In some embodiments, a six-axis sensor (e.g., ICM-20649) and a three-axis magnetometer (e.g., LIS2MDL) including an accelerometer and a gyroscope may be used as a nine-axis inertial sensor 121. The accelerometer senses the Earth's gravity and the acceleration generated by movement; the gyroscope senses the angular velocity generated by movement; and the magnetometer senses the Earth's magnetic field vector, which can be calculated to obtain azimuth angle information. Furthermore, the wireless communication unit 122 may be, for example, a Wi-Fi communication unit, a Bluetooth communication unit, or a 3G, 4G, 4G LTE, or 5G mobile network unit. This embodiment uses a Wi-Fi communication unit as an example.

[0036] like Figure 3As shown, the inertial sensing module 12 of this embodiment comprises, from bottom to top, a lower housing C1, an adhesive 126, a power supply unit 125, an inertial circuit board 123, a foot pressure function circuit board 124, and an upper housing C2. The lower housing C1 and upper housing C2, when combined, form a housing for the power supply unit 125, the inertial circuit board 123, and the foot pressure function circuit board 124. In this embodiment, the power supply unit 125, the inertial circuit board 123, and the foot pressure function circuit board 124 are secured to the housing formed by the lower housing C1 and upper housing C2 via an adhesive 126 (double-sided tape).

[0037] In this embodiment, the inertial sensor 121 and the wireless communication unit 122 may be disposed on an inertial circuit board 123, and the inertial circuit board 123 is electrically connected to a foot pressure function circuit board 124 (not shown). Furthermore, the foot pressure sensing assembly 11 may be electrically connected to the foot pressure function circuit board 124 and the inertial circuit board 123 via the extension portion 1121. Thus, the foot pressure signal PS generated by the pressure sensing pad 111 may be transmitted to the foot pressure function circuit board 124 and the inertial circuit board 123. Furthermore, the power supply unit 125 may be, for example, a lithium battery, which provides the power required for the operation of the inertial sensing module 12 and the foot pressure sensing assembly 11.

[0038] In this embodiment, the inertial circuit board 123 and the foot pressure function circuit board 124 are separate circuit boards, but this is not limiting. In various embodiments, the inertial circuit board 123 and the foot pressure function circuit board 124 may be integrated into a single component circuit board, which is not a limitation of the present invention. In one embodiment, the inertial sensing module 12 may further include a microcontroller unit (not shown). The microcontroller unit may be disposed on the inertial circuit board 123. The microcontroller unit may extract and collect the foot pressure signal PS and the inertial signal IS generated by the pressure sensing pad 111 and the inertial sensor 121 and process them (e.g., temporarily store and encode them). The processed foot pressure signal PS and inertial signal IS may be wirelessly transmitted to an electronic device (e.g., a computer, server, or cloud device) via the wireless communication unit 122 in real time or in batches, allowing the electronic device to analyze the motion status using these signals.

[0039] Please match Figure 3 and cooperate with Figure 1AIn this embodiment, the lower housing C1 of the inertial sensing module 12 has a through-hole C11 on each side thereof. For example, two straps 3 are passed through the two through-holes C11 on the side of the lower housing C1 and the shoelace holes 26 to secure the inertial sensing module 12 to the upper side of the shoe tongue 23. Of course, the securing method for the inertial sensing module 12 is not limited to this. In various embodiments, the inertial sensing module 12 may be secured to the upper 211 of the athletic shoe 2 using, for example, Velcro (not shown), a clamp (not shown), a buckle (not shown), or any combination of these securing methods. The present invention is not limited to these securing methods.

[0040] Figure 5 This is a structural schematic diagram of an insole and a foot pressure sensing assembly in a sports shoe according to another embodiment of the present invention.

[0041] like Figure 5 As shown, the components and connections of the sports shoe 2a of this embodiment are substantially the same as those of the sports shoe 2 of the previous embodiment. The difference lies in that, in this embodiment, the foot pressure sensing assembly 11 and the insole 24a are integrated into a single component. This integration of the foot pressure sensing assembly 11 and the insole 24 makes assembly and disassembly more convenient for the user. In one embodiment, the foot pressure sensing assembly 11 can be embedded or otherwise integrated into the insole 24a.

[0042] Figures 6A to 8B Schematic diagrams of inertial sensing modules according to different embodiments of the present invention from different viewing angles.

[0043] Please refer to Figure 6A and Figure 6B , the inertial sensing module 12a of this embodiment is roughly the same as the inertial sensing module 12 of the aforementioned embodiment. The main difference from the inertial sensing module 12 is that the inertial sensing module 12a of this embodiment is roughly cylindrical in shape, and the way it is fixed to the shoe upper 211 is different from the aforementioned embodiment. Here, the bottom B of the lower shell C1 of the inertial sensing module 12a is connected to the clamping member C12, and the inertial sensing module 12a can be fixed to the shoe upper 211 by clamping it on the shoelace 25 of the sports shoe through the clamping member C12. In one embodiment, the material of the clamping member C12 may be the same as or different from the material of the lower shell C1. In one embodiment, the clamping member C12 may be integrally formed with the lower shell C1, or fixed to the bottom B of the lower shell C1 by a fixing member (such as a screw), which is not limited by the present invention.

[0044] In addition, if Figure 7A and Figure 7BAs shown, the inertial sensing module 12b of this embodiment is substantially the same as the inertial sensing module 12a of the aforementioned embodiment. The main difference from the inertial sensing module 12a is that the bottom B of the lower housing C1 of the inertial sensing module 12b of this embodiment is connected to two opposing clamping members C13a and C13b. The clamping members C13a and C13b can be referred to as rotating clamping members. After the rotating clamping members (clamping members C13a and C13b) respectively clamp the shoelaces 25 of the sneakers, they can be rotated clockwise or counterclockwise to secure the inertial sensing module 12b to the shoelaces 25. In one embodiment, the material of the clamping members C13a and C13b can be the same as or different from the material of the lower housing C1. In one embodiment, the clamping members C13a and C13b can be integrally formed with the lower housing C1, or fixed to the bottom B of the lower housing C1 by fixing members (such as screws), but this is not limited by the present invention.

[0045] In addition, if Figure 8A and Figure 8B As shown, the inertial sensing module 12c of this embodiment is substantially identical to the inertial sensing module 12a of the previous embodiment. The primary difference from the inertial sensing module 12a is that the material of the clamping member C14 of the inertial sensing module 12c of this embodiment is different from that of the lower housing C1. The clamping member C14 can be made of, for example, stainless steel and can be secured to the bottom B of the lower housing C1 using fasteners (e.g., screws).

[0046] In addition, other technical contents of the inertial sensing modules 12a, 12b, and 12c are the same as those of the inertial sensing module 12 and are not further described here.

[0047] In summary, in the motion sensing device and sports shoes of the present invention, a foot pressure sensing component is disposed on the insole of the sports shoe and includes a plurality of pressure sensing pads. These pressure sensing pads are used to sense the pressure of the soles of the feet of the athlete wearing the sports shoe and output foot pressure signals. An inertial sensing module is electrically connected to these pressure sensing pads. The inertial sensing module is fixed to the upper of the sports shoe and is located on the tongue. The inertial sensing module includes an inertial sensor and a wireless communication unit. The inertial sensor is used to sense the inertial signal output by the athlete wearing the sports shoe when exercising. The wireless communication unit wirelessly transmits the foot pressure signal and the inertial signal. This structural design enables the motion sensing device and sports shoes of the present invention to achieve real-time feedback on the motion status for further analysis, thereby achieving the purpose of injury prevention and improved motion efficiency.
