[0001] The present invention relates to the field of speed and pressure change measuring devices, and in particular to a speed and pressure change measuring device based on motion state and a use method thereof. Background Art

[0002] Devices for measuring the speed and pressure changes of wearing shoes in motion are mainly used in the fields of sports science, rehabilitation medicine, smart fitness, health monitoring, etc. Such devices can accurately capture and analyze the user's gait, pressure, speed and other parameters during exercise, helping to improve sports performance and prevent sports injuries. Pressure sensors are integrated on insoles or soles to measure the pressure changes in various areas of the sole in real time. The collection of pressure data can reveal gait characteristics and exercise load, and through sensors such as accelerometers and gyroscopes, it can record the athlete's speed, cadence, stride and other exercise parameters in real time.

[0003] However, in actual applications, when the user measures the speed and pressure changes of the shoes in motion, the shoes will undergo speed and pressure changes during the test. Since the sensors of the speed and pressure change measuring device are attached to the inside of the sole by using colloid, for easy disassembly, the speed and pressure sensors may fall off and move inside the sole during the long-term speed and pressure test of the shoes. The falling off or movement of the sensors will cause the position of the sensors to change, making it impossible to accurately measure the pressure and motion state between the shoes and the ground. Summary of the invention

[0004] In order to solve the above technical problems, a speed and pressure change measuring device based on the motion state and a method for using the same are provided. The technical solution solves the problem raised in the above background technology that the sensors of the speed and pressure change measuring device are pasted to the inside of the sole by using a colloid for easy disassembly. However, during the long-term speed and pressure test of the shoes, the speed and pressure sensors may fall off and move inside the sole. The falling off or movement of the sensors will cause the position of the sensors to change, thereby failing to accurately measure the pressure and motion state between the shoes and the ground.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention is: A device for measuring speed and pressure changes based on a motion state comprises a shoe measuring body and a fixing component, wherein the fixing component comprises a handle, a pull rod is installed at one end of the handle, the pull rod passes through the interior of the sole, the pull rod passes through the interior of a fixing tube, the fixing tube is arranged inside a fixing block, a compression spring is arranged inside the fixing tube, one end of the compression spring is arranged at one end of a moving block, the moving block moves telescopically inside the fixing tube, one end of the pull rod is inserted and connected to the interior of a card block, one end of the card block is installed at one end of a shell, and a speed pressure sensor is arranged inside the shell.

[0006] Preferably, a mounting plate is provided at the lower end of the velocity pressure sensor, the lower end of the mounting plate is placed on the upper end of the magnetic attraction plate, and the lower end of the magnetic attraction plate is arranged at the bottom end inside the housing.

[0013] Preferably, the bottom film is arranged at the lower end of the lower plate, and the lower plate and the upper plate are connected and fixed by gluing a sealing glue.

[0014] A detection method for a reclaimed water recycling and filtering device is also provided. The method comprises: S1. The user can pull the handle, and the handle transmits force between the pull rod and the sole. The pull rod passes through the sole and is connected to the fixed cylinder. When the handle is operated, the pull rod moves the fixed cylinder, driving the internal compression spring, and further drives the moving block to move inside the fixed cylinder. The pull rod does not change the appearance and function of the original sports shoes. Wearable electronic devices. Adopt flexible electronic circuit design, intensive miniaturization, high-precision detection technology, high-precision positioning technology, high-precision pressure sensor, atomic clock high-precision timing; S2. When the handle is released, the elastic force of the compression spring further pushes the pull rod, thereby driving the pull rod to move, and the pull rod will be inserted into the inside of the card block, which can bind and fix the housing and the speed pressure sensor to ensure that the sensor will not move during the movement, and the stability is high; S3, and the speed pressure sensor is used to detect the pressure changes and movement speed changes of the sole. It captures the pressure in the movement, such as the ground reaction force when walking and running, and the speed, such as the acceleration change of movement, in real time through direct contact with the sole. When the force on the sole changes, the sensor will sense these changes and convert the data into electronic signals and output them to external devices such as mobile phones and smart watches for data analysis. MPXVDP pressure and speed sensor model: used to measure pressure and speed, widely used in sports equipment; S4. The lower mounting plate of the speed pressure sensor is contacted with the upper end of the magnetic plate. The magnetic plate is used to fix the mounting plate in a certain position by magnetic force and ensure that it is stable during movement. Magnets or other magnetic materials can be used to generate sufficient attraction so that the mounting plate and the speed pressure sensor are kept in a fixed position to avoid displacement when the external environment changes, such as gait changes. S5.

When the sole is subjected to external pressure, for example, human gait pressure or weight, the pressure is transmitted to the telescopic spring through the protective layer and the coil. The telescopic spring begins to expand and contract according to the size of the pressure, and is connected to the telescopic rod. The bottom plate is relatively displaced with the lower plate under the action of the external pressure, so that the telescopic rod moves and contracts inside the coil. When the external pressure increases, the telescopic spring is compressed; conversely, when the pressure decreases, the spring rebounds, and the lower plate is fixed together by the connection with the sealing body of the upper plate, providing a stable structure. The connection method ensures the firm combination of the two, reduces the impact on the foot and the speed pressure sensor, and prevents the pressure of the foot from damaging the speed pressure sensor.

The function of the spring is to push the pull rod to move by releasing the elastic force, so that the force between the handle and the sole is effectively transmitted. The pull rod can be inserted into the block, so that the housing and the speed pressure sensor can be fixed, ensuring that the speed pressure sensor will not be displaced during the shoe movement measurement process, avoiding unstable sensor movement during dynamic movement, thereby maintaining the accuracy of data collection, and enhancing the stability of the speed pressure sensor, which helps to achieve accurate pressure and speed data monitoring.

[0016] (2) In the present invention, the velocity pressure sensor can be firmly held in a fixed position by the magnetic force between the magnetic attraction plate and the mounting plate. Even during gait or movement, due to changes in pace, impact force or other external factors, the magnetic force can ensure that the sensor will not be displaced or shaken, thereby avoiding instability during data collection.

[0017] (3) The present invention ensures that the velocity pressure sensor always maintains the correct position during the entire use process, thereby improving the measurement accuracy. No matter how the sensor is affected by external forces during operation, the position of the sensor can be accurately controlled, avoiding data deviation caused by changes in the sensor position.

[0018] (4) In the present invention, when the sole is subjected to external pressure such as gait pressure or weight, the pressure is transmitted to the telescopic spring through the protective layer and the coil. The spring expands and contracts according to the pressure, plays a buffering role, reduces the impact on the foot and the speed pressure sensor, and prevents the pressure of the foot from damaging the speed pressure sensor.

DETAILED DESCRIPTION

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] Example 1 Please refer to Figure 1 , Figure 5-9 As shown, a speed and pressure change measurement device based on a motion state comprises a shoe measuring body 100 and a fixing assembly 300. The fixing assembly 300 comprises a handle 303. A pull rod 313 is installed at one end of the handle 303. The pull rod 313 passes through the interior of the sole 109. The pull rod 313 passes through the interior of a fixing cylinder 314. The fixing cylinder 314 is arranged inside a fixing block 307. A compression spring 315 is arranged inside the fixing cylinder 314. One end of the compression spring 315 is arranged at one end of a moving block 316. The moving block 316 moves telescopically inside the fixing cylinder 314. One end of the pull rod 313 is inserted and connected to the interior of a card block 306. One end of the card block 306 is installed at one end of a housing 301. A speed pressure sensor 400 is arranged inside the housing 301.

[0022] In actual use, the user can pull the handle 303, and the handle 303 transmits force between the pull rod 313 and the sole 109. The pull rod 313 passes through the sole 109 and is connected to the fixed cylinder 314. When the handle 303 is operated, the pull rod 313 moves the fixed cylinder 314, drives the internal compression spring 315, and further drives the moving block 316 to move inside the fixed cylinder 314. When the handle 303 is released, the elastic force of the compression spring 315 further pushes the pull rod 313, and then drives the pull rod 313 to move, and the pull rod 313 will be inserted into the inside of the block 306, which can bind and fix the housing 301 and the speed pressure sensor 400, ensuring that the sensor will not move during the movement, and the stability is high. The speed pressure sensor 400 is used to detect the pressure change and movement speed change of the sole 109. It captures the pressure in the movement such as the ground reaction force during walking and running and the speed such as the acceleration change of movement in real time through direct contact with the sole 109. When the force on the sole 109 changes, the sensor will sense these changes and convert the data into electronic signals and output them to external devices such as mobile phones, smart watches, etc. for data analysis. MPXV7002DP pressure and speed sensor model: used to measure pressure and speed, widely used in sports equipment, this device belongs to wearable electronic devices, and maintains the original functional properties of sports shoes. For example, the acceleration sensor is set inside the sports shoe: used to detect the pace, running speed, gait and posture changes. Pressure sensor: integrated in the sole, by sensing the force on the foot to analyze the gait, running efficiency, center of gravity changes, etc. Sports shoes usually have wireless communication functions and can synchronize data with mobile phones, smart watches and other devices. High-precision positioning, accuracy 1cm, time accuracy', 0.01s. High-precision positioning and pressure accuracy, as well as pressure distribution detection on the upper, pressure accuracy 0.01N, help set a value, the pressure sensor should be able to reflect, express the pressure change of the shoe touching the ground, the upper surface (except the sole) can reflect the pressure change value of contacting external objects, and can transmit data communication. When the shoe touches the ground, the pressure will be concentrated in the sole area, but it may also extend to part of the upper. Usually, when people walk, the pressure on the sole may vary from tens to hundreds of Pascals (Pa). For athletes or extreme load scenarios, the pressure value may be higher, even close to 1kPa to 10kPa. In order to ensure that the pressure sensor can accurately reflect the pressure change of the shoe in contact with the ground or external objects, it is more appropriate to choose a measurement range of 0-1000kPa (1MPa). The upper is usually curved, and the sensor needs to be able to adapt to this shape.Typically, pressure sensors can be thin film sensors (such as thin film piezoresistive, thin film capacitive, etc.), or flexible sensors. These sensors can flexibly fit the shape of the upper and accurately sense the pressure changes between the upper and external objects (such as the ground, walls or other objects). By integrating accelerometers and gyroscopes, the acceleration and angular velocity of the movement can be measured in real time in the shoe, and then the position change of the shoe at every moment can be calculated in combination with the timestamp. By setting multiple touch sensors on the sole, the pressure changes in each area can be accurately sensed to help analyze the gait pattern and movement state. Secondly, through the three-point positioning method and laser ranging technology, usually three key points on the shoe (such as the forefoot, heel and middle of the upper) are measured using a laser rangefinder. First, three specific points on the surface of the shoe (such as the forefoot, heel, and middle) are determined by image recognition or manual marking. These points are reference points with known positions. The laser rangefinder is aimed at these three points on the surface of the shoe. The laser rangefinder obtains the distance between the three points and the laser transmitter by emitting a laser beam and calculating the return time of the reflected light.

[0023] When the user pulls the handle 303, the rod 313 moves in the sole 109, driving the fixing tube 314 and the compression spring 315. The function of the spring is to push the rod 313 to move by releasing the elastic force, so that the force between the handle 303 and the sole 109 is effectively transmitted. The rod 313 can be inserted into the block 306, so that the housing 301 and the speed pressure sensor 400 can be fixed, ensuring that the speed pressure sensor 400 will not be displaced during the shoe movement measurement process, avoiding the unstable movement of the sensor in dynamic movement, thereby maintaining the accuracy of data collection, and the stability of the speed pressure sensor 400 is enhanced, which is conducive to accurate pressure and speed data monitoring. The rod does not change the appearance and function of the original sports shoes, and the wearable electronic device adopts flexible electronic circuit design, intensive miniaturization, high-precision detection technology, high-precision positioning technology, high-precision pressure sensor, and atomic clock high-precision timing.

[0024] Example 2 Please refer to Figure 7-8 As shown, a mounting plate 401 is provided at the lower end of the velocity pressure sensor 400, the lower end of the mounting plate 401 is placed on the upper end of the magnetic plate 402, the lower end of the magnetic plate 402 is arranged at the bottom end inside the shell 301, and slide grooves 308 are provided on both sides of the upper end of the shell 301, and the interior of the slide groove 308 is connected with a closing plate 302 by sliding.

[0025] In actual use, the lower end mounting plate 401 of the speed pressure sensor 400 is contacted with the upper end of the magnetic plate 402. The function of the magnetic plate 402 is to fix the mounting plate 401 in a certain position through magnetic force and ensure that it is stable during movement. Magnets or other magnetic materials can be used to generate sufficient attraction to keep the mounting plate 401 and the speed pressure sensor 400 in a fixed position to avoid displacement when the external environment changes, such as gait changes.

[0026] The speed pressure sensor 400 can be firmly held in a fixed position by the magnetic force between the magnetic attraction plate 402 and the mounting plate 401. Even during gait or movement, due to the influence of pace changes, impact force or other external factors, the magnetic force can ensure that the sensor will not be displaced or shaken, avoiding instability during data collection.

[0027] Example 3 Please refer to Figure 7 As shown, a connecting block 309 is fixedly installed on the upper end of the mounting plate 401, and a screw rod 312 is arranged inside the connecting block 309. The screw rod 312 is connected to the inside of a threaded barrel 311 by rotation. The threaded barrel 311 is arranged inside the housing 301, and a rotating handle 310 is installed at one end of the screw rod 312.

[0028] In actual use, the operator manually rotates the handle 310 to further drive the screw rod 312 to rotate, thereby driving the screw rod 312 to rotate inside the threaded barrel 311, and then the screw rod 312 moves back and forth in the threaded barrel 311, and the screw rod 312 rotates and moves inside the connecting block 309, further fixing the speed pressure sensor 400 inside the housing 301.

[0029] By ensuring that the velocity pressure sensor 400 always maintains the correct position during the entire use process, the measurement accuracy is improved. No matter how the sensor is affected by external forces during operation, the position of the sensor can be accurately controlled, avoiding data deviation caused by changes in the sensor position. Example 4 Please refer to Figure 1-6 As shown, a bottom plate 304 is fixedly installed at the lower end of the shell 301, and the bottom plate 304 is installed on the upper end of the protective layer 107 through fasteners 108. The protective layer 107 is installed on the inner bottom end of the sole 109 through fasteners 108. A ring tube 106 is installed on the upper end of the protective layer 107, and a telescopic spring 111 is arranged inside the ring tube 106. A telescopic rod 105 is installed on the upper end of the telescopic spring 111, and a bottom film 104 is installed on the upper end of the telescopic rod 105. The bottom film 104 is arranged at the lower end of the lower plate 102, and the lower plate 102 and the upper plate 101 are connected and fixed by gluing a sealing glue 103.

[0030] In actual use, when the sole 109 is subjected to external pressure, for example, the gait pressure or weight of a person, the pressure is transmitted to the telescopic spring 111 through the protective layer 107 and the ring tube 106. The telescopic spring 111 begins to expand and contract according to the magnitude of the pressure, and is connected to the telescopic rod 105. The bottom plate 104 is relatively displaced with the lower plate 102 under the action of the external pressure, so that the telescopic rod 105 is telescopically moved inside the ring tube 106. When the external pressure increases, the telescopic spring 111 is compressed; conversely, when the pressure decreases, the spring rebounds, and the lower plate 102 is fixed together by the connection with the sealing body 103 of the upper plate 101, providing a stable structure. The connection method ensures the firm combination of the two, reduces the impact on the foot and the speed pressure sensor 400, and prevents the pressure of the foot from damaging the speed pressure sensor 400.

[0031] When the sole 109 is subjected to external pressure such as gait pressure or weight, the pressure is transmitted to the telescopic spring 111 through the protective layer 107 and the ring tube 106. The telescopic spring 111 expands and contracts according to the pressure, thereby playing a buffering role, reducing the impact on the foot and the speed pressure sensor 400, and preventing the pressure of the foot from damaging the speed pressure sensor 400.

[0032] The working principle and use process of this device: S1. The user can pull the handle 303, and the handle 303 transmits force to the sole 109 through the pull rod 313. The pull rod 313 passes through the sole 109 and is connected to the fixed cylinder 314. When the handle 303 is operated, the pull rod 313 moves the fixed cylinder 314, drives the internal compression spring 315, and further drives the moving block 316 to move inside the fixed cylinder 314; S2. When the user releases the handle 303, the elastic force of the compression spring 315 further pushes the pull rod 313, thereby driving the pull rod 313 to move, and the pull rod 313 is inserted into the inside of the block 306, which can bind and fix the housing 301 and the speed pressure sensor 400, ensuring that the sensor does not move during the movement, and the stability is high; S3, and the speed pressure sensor 400 is used to detect the pressure change and movement speed change of the sole 109. It captures the pressure in the movement, such as the ground reaction force when walking and running, and the speed, such as the acceleration change of movement, in real time through direct contact with the sole 109. When the force on the sole 109 changes, the sensor will sense these changes and convert the data into electronic signals and output them to external devices such as mobile phones, smart watches, etc. for data analysis. MPXV7002DP pressure and speed sensor model: used to measure pressure and speed, widely used in sports equipment; S4, by contacting the lower end mounting plate 401 of the speed pressure sensor 400 with the upper end of the magnetic attraction plate 402, the magnetic attraction plate 402 is used to fix the mounting plate 401 in a certain position by magnetic force and ensure that it is stable during movement. Magnets or other magnetic materials can be used to generate sufficient attraction, so that the mounting plate 401 and the speed pressure sensor 400 are kept in a fixed position to avoid displacement when the external environment changes, such as gait changes; S5. The operator manually rotates the rotating handle 310 to further drive the screw rod 312 to rotate, thereby driving the screw rod 312 to rotate inside the threaded barrel 311, and then the screw rod 312 moves back and forth in the threaded barrel 311, and the screw rod 312 rotates and moves inside the connecting block 309, further fixing the speed pressure sensor 400 inside the housing 301; S6. When the sole 109 is subjected to external pressure, for example, the gait pressure or weight of a person, the pressure is transmitted to the telescopic spring 111 through the protective layer 107 and the ring tube 106. The telescopic spring 111 begins to expand and contract according to the size of the pressure, and is connected to the telescopic rod 105. The bottom plate 104 is relatively displaced with the lower plate 102 under the action of the external pressure, so that the telescopic rod 105 is telescopically moved inside the ring tube 106. When the external pressure increases, the telescopic spring 111 is compressed; conversely, when the pressure decreases, the spring rebounds, and the lower plate 102 is fixed together by the connection with the sealing body 103 of the upper plate 101, providing a stable structure. The connection method ensures the firm combination of the two, reduces the impact on the foot and the speed pressure sensor 400, and prevents the pressure of the foot from damaging the speed pressure sensor 400.

When the handle (303) is released, the elastic force of the compression spring (315) further pushes the pull rod (313), thereby driving the pull rod (313) to move, and the pull rod (313) is inserted into the inside of the block (306), so as to bind and fix the housing (301) and the speed pressure sensor (400), thereby ensuring that the sensor does not move during the movement, and the stability is high; S3, and the speed pressure sensor (400) is used to detect the pressure change and movement speed change of the sole (109). It captures the pressure in the movement, such as the ground reaction force during walking and running, and the speed, such as the acceleration change of movement, in real time through direct contact with the sole (109). When the force on the sole (109) changes, the sensor will sense these changes and convert the data into electronic signals and output them to external devices such as mobile phones, smart watches, etc. for data analysis. MPXV (7002) DP pressure and speed sensor model: used to measure pressure and speed, widely used in sports equipment; S4, by contacting the lower end mounting plate (401) of the speed pressure sensor (400) with the upper end of the magnetic attraction plate (402), the magnetic attraction plate (402) is used to fix the mounting plate (401) at a certain position by magnetic force and ensure that it is stable during movement, and a magnet or other magnetic material can be used to generate sufficient attraction, so that the mounting plate (401) and the speed pressure sensor (400) are kept in a fixed position to avoid displacement when the external environment changes, such as when the gait changes; S5. The operator manually rotates the rotating handle (310), thereby further driving the screw rod (312) to rotate, thereby driving the screw rod (312) to rotate inside the threaded barrel (311), and then the screw rod (312) moves forward and backward in the threaded barrel (311), and the screw rod (312) rotates and moves inside the connecting block (309), further fixing the speed pressure sensor (400) inside the housing (301); S6. When the sole (109) is subjected to external pressure, for example, the gait pressure or weight of a person, the pressure is transmitted to the telescopic spring (111) through the protective layer (107) and the ring tube (106). The telescopic spring (111) begins to expand and contract according to the magnitude of the pressure, and is connected to the telescopic rod (105). Under the action of the external pressure, the bottom plate (104) and the lower plate (102) are relatively displaced, so that the telescopic rod (105) moves telescopically inside the ring tube (106). When the external pressure increases, the telescopic spring (111) is compressed; conversely, when the pressure decreases, the spring rebounds. The lower plate (102) is fixed together by connecting with the sealing body (103) of the upper plate (101), providing a stable structure. The connection method ensures that the two are firmly combined, reducing the impact on the foot and the speed pressure sensor (400), and preventing the pressure of the foot from damaging the speed pressure sensor (400).
