Description

Technical Field

[0001] This application relates to the field of footwear technology, specifically to an anti-bending control system for shoe soles and a shoe. Background Technology

[0002] A shoe sole typically consists of an outsole, midsole, and insole. The outsole is the part of the sole that contacts the ground, and its main functions are slip resistance and abrasion resistance. The insole is the part of the sole that directly contacts the foot, and its main functions are sweat absorption and quick-drying. The midsole is located between the outsole and insole, and its main functions are to provide cushioning, shock absorption, rebound, and flexural strength. The flexural strength of the sole is mainly related to the midsole. The flexural strength of the midsole is usually a fixed value. However, users have different needs for the flexural strength of the midsole in different sports and wearing scenarios. During sports, the flexural strength of the midsole needs to be increased, while during casual wear, the flexural strength of the midsole needs to be decreased.

[0003] To address the aforementioned needs, this utility model provides an adjustable midsole with bend resistance. The midsole features a rigid sliding member, and the bend resistance is adjusted by changing the relative position of the sliding member and the midsole body along the front-to-back direction. While this utility model fulfills the requirement of adjustable midsole bend resistance, the method of adjusting the relative position of the sliding member and the midsole body relies on manual adjustment or a mechanical switch, which is cumbersome and lacks convenience and intelligence. Utility Model Content

[0004] The purpose of this application is to overcome the aforementioned defects or problems in the prior art and to provide a sole bending resistance control system that uses electroencephalography (EEG) and electromyography (EMG) to intelligently adjust the sole bending resistance.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] A shoe sole anti-flexure control system includes: a midsole comprising a midsole body, a sliding member, and a driving member, wherein the sliding member and the driving member are both mounted on the midsole body, the sliding member is rigid and extends in a front-to-back direction, and the driving member drives the sliding member to slide relative to the midsole body in a front-to-back direction; and a signal processing module comprising a first sensor, a second sensor, and a signal processor, wherein the first sensor is mounted at a position on the head corresponding to a brain region to acquire brain electrical signals, the second sensor is mounted at a position on the head corresponding to a masseter muscle to acquire masseter muscle electrical signals, and the signal processor is signal-connected to the first sensor, the second sensor, and the third sensor. A first sensor and a second sensor are provided to process brain electrical signals and masseter muscle electrical signals into electroencephalogram (EEG) characteristic values ​​and electromyogram (EMG) characteristic values, respectively; and a controller is connected to the signal processor and the actuator. The controller compares the EEG characteristic values ​​with EEG thresholds and the EMG characteristic values ​​with EMG thresholds, and determines the state of the human body based on the comparison results. When the human body is in a tense state, the controller controls the actuator to drive the slider forward to enhance bending resistance. When the human body is in a relaxed state, the controller controls the actuator to drive the slider backward to reduce bending resistance.

[0007] Furthermore, when the electromyographic characteristic value is greater than or equal to the electromyographic threshold, the controller determines that the human body is in a state of tension; when the electroencephalogram (EEG) characteristic value is greater than or equal to the EEG threshold and the electromyographic characteristic value is less than the EMG threshold, the controller determines that the human body is in a state of relaxation.

[0008] Furthermore, the driving component is a motor, which drives the sliding component to slide forward or backward by rotating forward or in reverse.

[0009] Furthermore, both the first and second sensors are mounted on the wearable headband.

[0010] Furthermore, the signal processor and the controller are located in a mobile terminal, which can set the EEG threshold and the EMG threshold.

[0011] Furthermore, the mobile terminal is provided with a forward button and a backward button. Pressing the forward button causes the mobile terminal to control the driving component to drive the slider to slide forward; pressing the backward button causes the mobile terminal to control the driving component to drive the slider to slide backward.

[0012] Furthermore, the midsole body is provided with a groove extending in the front-to-back direction, and the slider slides in the groove in the front-to-back direction.

[0013] Furthermore, the midsole body is provided with a cable, which connects the two ends of the slider and extends out of the groove to connect with the drive member. The drive member pulls the cable to drive the slider to slide in the groove in the front-back direction.

[0014] Furthermore, the sliding component is made of carbon fiber.

[0015] In addition, this utility model also provides a shoe, including a sole bending resistance control system as described in any of the above claims.

[0016] Compared with existing technologies, the above solution has the following beneficial effects:

[0017] 1. The shoe midsole includes a midsole body, a sliding component, and a driving component. The midsole body is equipped with the sliding component and the driving component. The sliding component is rigid and extends in the front-to-back direction. When the sliding component extends in the front-to-back direction and is located at the front end of the midsole body, it can bend along with the bending of the midsole body. The rigidity of the sliding component, when bending along with the midsole body, enhances the bending resistance of the midsole body, thereby improving the bending resistance of the sole. The driving component drives the sliding component to slide relative to the midsole body in the front-to-back direction. When the driving component drives the sliding component forward to the front end of the midsole body, the sliding component bends along with the bending of the midsole body, enhancing the bending resistance of the midsole. When the driving component drives the sliding component backward to the rear end of the midsole body, the sliding component does not bend along with the bending of the midsole body, reducing the bending resistance of the midsole. Compared to the usual method of adding an immovable rigid component to the midsole body to improve the bending resistance of the sole, or changing the bending resistance of the sole by manually adjusting the position of the rigid component in the midsole body, the adjustment of the bending resistance of the sole provided by this utility model is more convenient.

[0018] The first sensor acquires electrical signals from the brain, and the second sensor acquires electrical signals from the masseter muscle. The signal processor processes the acquired brain and masseter muscle electrical signals into EEG characteristic values ​​and EMG characteristic values, respectively. The controller compares the EEG characteristic values ​​with EEG thresholds and the EMG characteristic values ​​with EMG thresholds, and determines the state of the human body based on the comparison results. Then, based on the state of the human body, it controls the drive component to drive the slider forward or backward. Normally, adjusting the position of the slider is done manually or via a mechanical switch. This invention provides an EEG intelligent control system that intelligently controls the slider to slide forward or backward. When the EEG control system determines that the human body is in a tense state, it controls the drive component to drive the slider forward. When the slider is at the front end of the midsole body, it bends along with the midsole body, enhancing the sole's bending resistance. When the EEG control system determines that the human body is in a relaxed state, it controls the drive component to drive the slider backward. When the slider is at the rear end of the midsole body, it reduces the sole's bending resistance. The brainwave control system adjusts the sole's flexibility, freeing the user's hands and allowing them to adjust the sole's flexibility without stopping their hand movements. This intelligent adjustment method enhances the user experience. During intense exercise, the body is usually in a state of tension, requiring the sole to provide stronger flexibility to aid in running, jumping, and other activities. The design of enhancing the sole's flexibility by determining the body's tension through clenching the teeth aligns with the design philosophy of sole flexibility. When the body is relaxed, the brain is usually in a relaxed state, requiring the sole to provide better energy absorption and shock absorption for comfortable walking. The design of reducing the sole's flexibility by determining the body's relaxation through brainwaves also aligns with the design philosophy of sole flexibility.

[0019] 2. The control system determines the body's state based on the following criteria: When the electromyographic (EMG) characteristic value is greater than the EMG threshold, the body is determined to be in a state of tension. A state of tension often involves clenching the teeth. The EMG threshold is the EMG characteristic value of the masseter muscle during clenching. When the controller compares the EMG characteristic value to this threshold and finds it greater than the threshold, it indicates that the body has performed the clenching action to a preset degree, meaning the body is in a state of tension. The electroencephalogram (EEG) threshold is the EEG characteristic value of the body in a relaxed state. When the controller compares the EEG characteristic value to this threshold and finds it greater than the threshold while the EMG characteristic value is less than the threshold, the body is determined to be in a relaxed state. Through these comparisons, the body's state can be determined, and the shoe sole's bending resistance can be intelligently adjusted accordingly.

[0020] 3. The drive mechanism uses a motor, which drives the sliding component forward or backward by rotating in either direction. Using a motor is more convenient than the commonly used manual adjustment. Simultaneously, the controller can adjust the forward or reverse rotation of the drive motor based on the comparison results of EEG and EMG characteristic values ​​with thresholds, thereby adjusting the bending stiffness of the shoe sole.

[0021] 4. The first and second sensors are used to collect electroencephalogram (EEG) and electromyogram (EMG) signals and need to be attached to the skin of the corresponding areas of the head. Both the first and second sensors are mounted on a wearable headband, which is convenient to carry and allows the first and second sensors to be attached to the scalp more easily.

[0022] 5. Both the signal processor and controller are located on the mobile terminal, making them easily portable. The mobile terminal allows setting EEG and EMG thresholds. Since EEG and EMG signals vary from person to person, setting these thresholds allows for a more accurate determination of the individual's state.

[0023] 6. EEG and EMG signals are affected by the environment. When environmental influences prevent the comparison between EEG characteristic values ​​and EEG thresholds, and EMG characteristic values ​​and EMG thresholds from accurately determining the state of the human body, the forward and backward buttons on the mobile terminal can be used to control the drive components, adjust the bending resistance of the shoe sole, and allow the control system to adapt to more usage environments.

[0024] 7. The slider slides in the front-to-back direction within the midsole body. The groove provides a channel for the slider to slide in the front-to-back direction, and the groove can make the slider slide more smoothly.

[0025] 8. The cable connects both ends of the slider and extends out of the groove to connect with the drive component. The drive component drives the slider to slide in the groove in the front-to-back direction by retracting the cable. The sliding of the slider in the front-to-back direction can be achieved by retracting the cable. The cable itself is lightweight, reducing the weight of the shoe sole and production costs.

[0026] 9. The sliding parts are made of carbon fiber. Carbon fiber is lightweight and can provide rigidity to the sole, as well as provide a boost to the user when it recovers its deformation.

[0027] 10. In the shoe, the aforementioned sole flexural resistance control system is combined with other components of the shoe to form a complete shoe structure. Attached Figure Description

[0038] In the claims and description, unless otherwise specified, the term "have" means that a technical feature that follows is part of a technical feature that precedes it.

[0039] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings.

[0040] See Figure 1 , Figure 1 This diagram shows a top-view view of the left shoe midsole structure provided in this embodiment. Figure 2 The wearable headband provided in this embodiment is shown. Figure 3 A schematic diagram of a shoe sole bending resistance control system provided in this embodiment is shown.

[0041] Figure 1The provided left shoe midsole bottom view is based on the orientation of the sole, specifically the direction from the point of contact with the ground to the point of contact with the foot. The midsole includes a midsole body 10, a slider 1, and a drive component 2. Both slider 1 and drive component 2 are mounted on the midsole body 10. Slider 1 is rigid and extends in the forefoot direction. The forefoot direction is based on the orientation of the foot, specifically the direction from the toe to the heel. During use, the shoe primarily bends in the forefoot area, and the sole's bending resistance mainly depends on the forefoot bending resistance of the midsole body 10. When slider 1 is located in the forefoot area of ​​the midsole body 10, bending of the midsole body 10 causes slider 1 to bend along with it. Slider 1 is made of highly rigid carbon fiber, and its bending along with the midsole body 10 enhances the sole's bending resistance. The length of the slider 1 extending in the front-to-back direction is such that when the slider 1 is located at the forefoot of the midsole body 10, it can bend along with the bending of the midsole body 10, thereby enhancing the bending resistance of the sole. In this embodiment, when the slider 1 is located at the forefoot of the midsole body 10, the front end of the slider 1 is located in the toe area of ​​the midsole body 10, and the rear end of the slider 1 is located in the arch area of ​​the midsole body 10. Using this length, the slider 1 can distribute the force to various parts of the sole. The driving member 2 drives the slider 1 to slide relative to the midsole body 10 in the front-to-back direction. In this embodiment, by driving the slider 1 to slide in the front-to-back direction, the relative position of the slider 1 in the front-to-back direction of the midsole body 10 is changed, thereby adjusting the bending resistance of the sole. The slider 1 slides forward to the front end of the midsole body 10, that is, the slider 1 is located at the forefoot of the midsole body 10, which increases the flexural strength of the sole; the slider 1 slides backward to the rear end of the midsole body 10, that is, the slider 1 is not located at the forefoot of the midsole body 10, which reduces the flexural strength of the sole.

[0042] The signal processing module includes a first sensor 51, a second sensor 52, and a signal processor. The first sensor 51 is installed at a location on the head corresponding to a brain region to acquire brain electrical signals, and the second sensor 52 is installed at a location on the head corresponding to the masseter muscle to acquire masseter muscle electrical signals. Electrical signals present in the human body reflect normal physiological activities. Whether at rest or in motion, the human body possesses bioelectrical signals closely related to life activities. Electroencephalogram (EEG) signals are generated by the activity of brain neurons and contain a large amount of electrophysiological information from brain nerve cells, reflecting human thought processes. Existing technologies can determine the state and degree of a person's state by processing and analyzing EEG signals of various frequency bands generated by brain nerve cells. In this embodiment, processing and analyzing EEG signals of various frequency bands determines whether the person is in a relaxed state and the degree of relaxation. The first sensor 51 is equipped with acquisition electrodes attached to the skin to acquire brain electrical signals of various frequency bands. Electromyographic (EMG) signals are bioelectrical signals generated by muscle activity and contain relevant information about limb movement. The amplitude and density of EMG signals change with muscle movement. Existing technology can determine muscle movement state by processing and analyzing the amplitude and density of electromyographic (EMG) signals. The amplitude and density of the masseter muscle EMG signal vary depending on the force exerted when clenching the teeth. In this embodiment, clenching the teeth represents a state of tension. The second sensor 52 is equipped with a collection electrode attached to the skin to acquire the masseter muscle EMG signal. Since EEG and EMG signals are weak, placing the collection electrode close to the area where signals need to be acquired can reduce the attenuation of EEG and EMG signals due to long transmission distances and also reduce interference from other signals. The signal processor connects to the first sensor 51 and the second sensor 52, processing the brain EMG signal and the masseter muscle EMG signal into EEG characteristic values ​​and EMG characteristic values, respectively. The first sensor 51 and the second sensor 52 acquire EEG and EMG signals and transmit them to the signal processor via Bluetooth. The signal processor filters the acquired EEG and EMG signals to remove noise interference. Then, it uses an EEG signal processing algorithm to analyze the EEG signals in different frequency bands and converts them into EEG feature values. Similarly, it uses an EMG processing algorithm to analyze the amplitude and density of the processed masseter muscle EMG signals and converts them into EMG feature values. Both EEG and EMG feature values ​​are digital signals; converting them to digital signals facilitates subsequent analysis and processing.

[0043] The controller connects to the signal processor and drive unit 2 via Bluetooth to wirelessly control the drive unit 2. The sole does not need to be equipped with a controller and signal processor, which reduces the weight of the sole. At the same time, the controller and signal processor are less likely to be damaged, improving the overall stability of operation.

[0044] In this embodiment, the EEG threshold is the range of EEG characteristic values ​​obtained after processing the brain electrical signals when the brain is in a relaxed state; the EMG threshold is the range of EMG characteristic values ​​obtained after processing the masseter muscle electrical signals during teeth clenching. The signal processor transmits the processed EEG and EMG characteristic values ​​to the controller. The controller compares the EEG characteristic values ​​with the EEG threshold and the EMG characteristic values ​​with the EMG threshold, and determines the state of the human body based on the comparison results. Comparing the EEG characteristic values ​​with the EEG threshold for a relaxed state determines whether the human body is in a relaxed state; comparing the EMG characteristic values ​​with the EMG threshold for a clenching state determines whether the human body is in a tense state. When the controller determines that the human body is in a tense state, it controls the drive component 2 to drive the slider 1 forward to the front end of the midsole body 10, enhancing the bending resistance of the sole. When the controller determines that the human body is in a relaxed state, it controls the drive component 2 to drive the slider 1 backward to the rear end of the midsole body 10, reducing the bending resistance of the sole. This utility model provides users with a control system that can intelligently adjust the bending resistance of the sole using EEG and EMG according to their own needs. When facing different sports and life scenarios, the control system using EEG and EMG breaks away from the more traditional control methods currently used, such as manual or mechanical switches and electric adjustments. When the body is in a state of tension, it means that the user is engaged in high-intensity exercise, which requires enhanced flexibility of the sole; when the body is in a relaxed state, it means that the user is engaged in low-intensity exercise, which requires reduced flexibility of the sole and improved comfort.

[0045] In a preferred embodiment, when the electromyographic (EMG) characteristic value is greater than or equal to the EMG threshold, the controller determines that the human body is in a state of tension. When the human body is in a state of tension, it usually clenches its teeth. The greater the force of clenching, the greater the EMG characteristic value of the masseter muscle. When the EMG characteristic value is greater than or equal to the EMG threshold, the controller controls the drive component 2 to drive the slider 1 forward to the front end of the midsole body 10, increasing the bending resistance of the sole. When the electroencephalogram (EEG) characteristic value is greater than or equal to the EEG threshold and the EMG characteristic value is less than the EMG threshold, the controller determines that the human body is in a relaxed state. When the human body is in a relaxed state, the higher the degree of relaxation, the greater the EEG characteristic value. In this embodiment, in addition to comparing the EEG characteristic value with the EEG threshold, the controller also compares the EMG characteristic value with the EMG threshold, and determines the relaxed state by combining the EEG comparison results and the EMG comparison results. When the EEG characteristic value is greater than or equal to the EEG threshold, and the EMG characteristic value is less than the EMG threshold, the controller determines that the human body is in a relaxed state. The controller controls the drive component 2 to drive the slider 1 to slide backward to the rear end of the midsole body 10, reducing the flexural strength of the sole. When the EEG characteristic value is greater than or equal to the EEG threshold, and the EMG characteristic value is also greater than or equal to the EMG threshold, the controller determines that the human body is in a tense state. The controller controls the drive component 2 to drive the slider 1 to slide forward to the front end of the midsole body 10, increasing the flexural strength of the sole. When both the EEG characteristic value and the EMG characteristic value are less than the EEG threshold, the controller does not control the drive component 2.

[0046] Existing technology can determine the state and degree of relaxation of the human body by processing and analyzing the electroencephalogram (EEG) signals of various frequency bands generated by brain nerve cells. It can also determine the state and degree of focus of the human body. In other embodiments, after processing and analyzing the EEG signals, they are converted into EEG relaxation characteristic values ​​and EEG focus characteristic values. The controller compares the electromyographic characteristic values ​​with the electromyographic threshold, and the EEG relaxation characteristic values ​​with the EEG relaxation threshold and the EEG focus characteristic values ​​with the EEG focus threshold. When the electromyographic characteristic value is greater than or equal to the electromyographic threshold, the controller controls the drive component 2 to drive the slider 1 forward to the front end of the midsole body 10, increasing the bending resistance of the sole. When either the EEG relaxation characteristic value is greater than or equal to the EEG relaxation threshold, or the EEG focus characteristic value is greater than or equal to the EEG focus threshold, and either of these two comparison results exists, and the electromyographic characteristic value is less than the electromyographic threshold, the controller determines that the human body is in a relaxed or focused state. When the human body is in a relaxed or focused state, the controller controls the drive component 2 to drive the slider 1 backward to the rear end of the midsole body 10, reducing the bending resistance of the sole.

[0047] In a preferred embodiment, the drive component 2 uses a motor. The motor drives the slider 1 to slide forward to increase the sole's bending resistance or slide backward to decrease it by rotating forward or backward. The adjustment method is more convenient, as the bending resistance of the sole is increased or decreased by rotating the motor forward or backward. In this embodiment, the drive component 2 is located above the slider 1. The direction "above" is based on the orientation of the sole. The vertical direction of the sole is from the point of contact with the foot to the point of contact with the ground. The drive component 2 is located above the slider 1, meaning it is closer to the foot than the slider 1. The drive component 2 is housed in a rigid shell and installed in the midsole body 10 at the arch of the foot. Due to the physiological characteristics of the foot, this area has more space to accommodate the drive component 2 compared to other parts of the foot. Simultaneously, this area experiences less stress than other parts of the foot, making the drive component 2 less prone to damage.

[0048] In a preferred embodiment, the first sensor 51 and the second sensor 52 are placed on the wearable headband 50. The first sensor 51 is installed on the forehead area of ​​the headband 50 to collect brain electrical signals; the second sensor 52 is installed on the back of the headband 50 to collect masseter muscle electrical signals. The first sensor 51 and the second sensor 52 are attached to the areas where signals are to be collected, reducing the transmission distance of the EEG and EMG signals and preventing signal attenuation due to excessive transmission distance. The contact areas between the first sensor 51 and the scalp of the second sensor 52 are both metal, which facilitates signal conduction. The headband 50 also contains a signal module, a battery module, etc. The headband 50 is easy to wear, comfortable for the user, and allows for simultaneous collection and transmission of EEG and EMG signals.

[0049] Preferably, the signal processor and controller are located in the mobile terminal, and the EEG and EMG thresholds can be set using the mobile terminal. In this embodiment, the mobile terminal is a mobile phone, which integrates a signal processor, controller, and transmission module. The EEG and EMG signals collected by the first sensor 51 and the second sensor 52 are transmitted to the mobile phone's APP via Bluetooth. The mobile phone's APP converts the EEG and EMG signals into EEG feature values ​​and EMG feature values, then compares the EEG feature values ​​with the EEG threshold and the EMG feature values ​​with the EMG threshold, and determines whether the human body is in a tense or relaxed state based on the comparison results. According to different human states, the mobile phone's Bluetooth module controls the drive component 2 to drive the slider 1 to slide forward or backward. The EEG and EMG thresholds can be set through the mobile phone's APP. The EEG feature values ​​obtained after processing the EEG signals of different frequency bands in different human relaxation states will be different. When different human bodies perform teeth clenching actions, the amplitude and density of the biting EMG signal will be different after processing the EMG feature values. Setting different thresholds for EEG and EMG allows for a more accurate determination of the user's state based on the comparison between EEG characteristic values ​​and EEG thresholds, as well as EMG characteristic values ​​and EMG thresholds. In practice, if an EMG characteristic value is judged as tense if it is only slightly greater than or equal to the EMG threshold for a very short time, or if an EEG characteristic value is judged as relaxed if it is slightly greater than or equal to the EEG threshold for a very short time while the EMG characteristic value is slightly less than or equal to the EMG threshold, the controller will incorrectly determine the user's state. In this embodiment, the mobile app can set the duration of the signal characteristic values. For example, setting the signal duration to 3 seconds means that the controller only determines the user is tense when the EMG characteristic value is greater than or equal to the EMG threshold for more than 3 seconds; conversely, it determines the user is relaxed when the EEG characteristic value is greater than or equal to the EEG threshold for more than 3 seconds while the EMG characteristic value is slightly less than or equal to the EMG threshold. Setting the signal duration allows for a more accurate determination of the user's state.

[0050] Preferably, the mobile terminal is equipped with a forward button and a backward button. Electroencephalogram (EEG) and electromyogram (EMG) signals are susceptible to interference from the surrounding environment, such as electromagnetic fields and noise, during use, making it impossible to accurately determine the user's state. In this embodiment, the mobile phone's app has forward and backward buttons to control the drive component 2. Pressing the forward button causes the mobile terminal to control the drive component 2, which in turn drives the slider 1 forward, enhancing the sole's bending resistance; pressing the backward button causes the mobile terminal to control the drive component 2, which in turn drives the slider 1 backward, reducing the sole's bending resistance. Using the forward and backward buttons allows the sole bending resistance control system to adapt to more usage environments.

[0051] Preferably, the midsole body 10 is provided with a groove 3 extending in the front-to-back direction, and the slider 1 slides in the groove 3 in the front-to-back direction. The midsole body 10 is provided with a cable 4, which connects the two ends of the slider 1 and extends out of the groove 3 to connect with the drive member 2. The drive member 2 drives the slider 1 to slide in the groove 3 in the front-to-back direction by retracting the cable 4. The groove 3 extending in the front-to-back direction facilitates the sliding of the slider 1 in the front-to-back direction of the midsole body 10. In this embodiment, the midsole body 10 is provided with four grooves 3, which are arranged in the left-to-right direction. Each groove 3 is provided with a slider 1, and the two ends of each slider 1 are respectively connected to the cable 4. The left-to-right direction mentioned above is based on the orientation of the foot. Figure 1 This is a bottom view of the left shoe midsole, with the thumb to little finger pointing left and right. The four grooves 3 are arranged in the left-right direction, but this does not mean they must be parallel. The arrangement of the four grooves 3 ensures that the sliding member 1 and the cable 4 housed within them do not interfere with the sliding. The cable 4 connects both ends of each sliding member 1 and extends out of the groove 3 to connect with the drive member 2. In this embodiment, the drive member 2 pulls all four cables 4 simultaneously, thus simultaneously driving all four sliding members 1 to slide forward or backward. A guide tube can also be provided within the groove 3, fixed to the midsole body 10. Since the sliding member 1 and cable 4 are typically harder than the midsole body 10, their sliding within the midsole body 10 can easily damage it. By providing a guide tube within the midsole body 10, the sliding member 1 and cable 4 can slide within the guide tube, better protecting the midsole body 10. Alternatively, the sliding member 1 can be driven forward or backward using methods other than the cable 4.

[0052] In addition, this utility model also provides a shoe that includes the above-mentioned sole anti-bending system.

[0053] This invention provides a shoe sole bending resistance control system and a shoe, including a midsole, a signal processing module, and a controller. The midsole includes a midsole body 10, a slider 1, and a drive component 2. Both the slider 1 and the drive component 2 are mounted on the midsole body 10. The slider 1 is made of carbon fiber and extends in the front-to-back direction. When the slider 1 is located at the forefoot of the midsole body 10, it can be bent along with the midsole body 10. The bending resistance of the slider 1 is greater than that of the midsole body 10. When it bends along with the midsole body 10, the bending resistance of the midsole body 10 is enhanced, thereby improving the bending resistance of the shoe sole. The drive component 2 drives the slider 1 to slide in the front-to-back direction within the midsole body 10. When the slider 1 slides to the front end of the midsole body 10, it is also located at the forefoot, at which point the bending resistance of the shoe sole is enhanced; when the slider 1 slides to the rear end of the midsole body 10, it is not located at the forefoot, at which point the bending resistance of the shoe sole is reduced. The signal processing module includes a wearable headband 50. A first sensor 51 is installed on the forehead area of ​​the headband to acquire brain electrical signals, and a second sensor 52 is installed behind the ear to acquire masseter muscle electrical signals. The first sensor 51 and the second sensor 52 transmit the acquired EEG and EMG signals to a signal processor. The signal processor filters the EEG and EMG signals to remove noise and other interference, and then uses an algorithm to process the EEG signals of various frequency bands into EEG feature values, and processes the EMG signals into EMG feature values ​​based on their amplitude and density. The EEG and EMG feature values ​​are digital signals; converting electrical signals into digital signals facilitates subsequent comparisons. After processing the EEG and EMG signals into EEG and EMG feature values, the signal processor transmits them to a controller. The controller compares the EEG feature values ​​with EEG thresholds and the EMG feature values ​​with EMG thresholds, and determines the human body state based on the comparison results. When the electromyographic characteristic value is greater than the electromyographic threshold, it is determined that the human body is in a state of tension. The controller controls the drive component 2 to drive the slider 1 to slide forward, increasing the bending resistance of the sole. When the electroencephalogram (EEG) characteristic value is greater than the EEG threshold and the electromyographic characteristic value is less than the EMG threshold, it is determined that the human body is in a state of relaxation. The controller controls the drive component 2 to drive the slider 1 to slide backward, reducing the bending resistance of the sole.
