Description

Technical Field

[0001] The present application relates to the technical field of shoes, and in particular to a bending resistance control system for a shoe sole and a shoe. Background Art

[0002] The sole usually includes the outsole, midsole and insole. The outsole is the part of the sole that contacts the ground, and its main functions are anti-slip and wear-resistant. 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 the insole, and its main functions are to provide cushioning, shock absorption, rebound and bending resistance. The bending resistance of the sole is mainly related to the midsole. The bending resistance of the midsole is usually a fixed value. Users have different requirements for the bending resistance of the midsole in different sports states and wearing scenarios. The bending resistance of the midsole needs to be increased during exercise, and the bending resistance of the midsole needs to be reduced during leisure.

[0003] In response to the above needs, a midsole with adjustable bending resistance is invented. A rigid sliding member is provided in the midsole. The bending resistance of the midsole is adjusted by adjusting the relative position of the sliding member and the midsole body in the front-to-back direction. Although the invention meets the need to adjust the bending resistance of the midsole, the relative position of the sliding member and the midsole body is adjusted manually or by a mechanical switch. The adjustment method is cumbersome and not convenient or intelligent enough. Summary of the invention

[0004] The purpose of the present application is to overcome the above-mentioned defects or problems existing in the background technology and to provide a sole bending resistance control system which utilizes brain electricity and myoelectricity to intelligently adjust the bending resistance of the sole.

[0005] In order to achieve the above purpose, the following technical solutions are adopted:

[0006] A shoe sole bending resistance control system comprises: a shoe midsole, which comprises 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 has rigidity and extends in the front-to-back direction, and the driving member drives the sliding member to slide relative to the midsole body in the front-to-back direction; a signal processing module, which comprises a first sensor, a second sensor and a signal processor, wherein the first sensor is mounted at a position of the head corresponding to the brain area to obtain brain electrical signals, the second sensor is mounted at a position of the head corresponding to the masseter muscle to obtain masseter muscle electrical signals, and the signal processor signal is connected to the first sensor, a second sensor and a signal processor. A sensor and a second sensor are used to process brain electrical signals and masseter muscle electrical signals into EEG characteristic values ​​and myoelectric characteristic values ​​respectively; and a controller is connected to the signal processor and the drive member signal, the controller compares the EEG characteristic values ​​with the EEG threshold value and the myoelectric characteristic values ​​with the myoelectric threshold value, and determines the state of the human body according to the comparison result; when the human body is in a tense state, the controller controls the drive member to drive the sliding member to slide forward to enhance the bending resistance, and when the human body is in a relaxed state, the controller controls the drive member to drive the sliding member to slide backward to reduce the 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 tense state; when the electroencephalogram characteristic value is greater than or equal to the electroencephalogram threshold and the electromyographic characteristic value is less than the electromyographic threshold, the controller determines that the human body is in a relaxed state.

[0008] Furthermore, the driving member is a motor, and the motor drives the sliding member to slide forward or backward by forward or reverse rotation.

[0009] Furthermore, the first sensor and the second sensor are both installed on a wearable headband.

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

[0011] Furthermore, the mobile terminal is provided with a forward button and a backward button, and by pressing the forward button, the mobile terminal controls the driving member to drive the sliding member to slide forward; by pressing the backward button, the mobile terminal controls the driving member to drive the sliding member to slide backward.

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

[0013] Furthermore, the midsole body is provided with a cable, which connects two ends of the sliding member and extends out of the slide groove to be connected to the driving member, and the driving member pulls the cable to drive the sliding member to slide in the slide groove along the front-rear direction.

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

[0015] In addition, the present invention also provides a shoe, comprising a sole bending resistance control system as described in any one of the above items.

[0016] Compared with the prior art, the above solution has the following beneficial effects:

[0017] 1. The midsole of a shoe comprises a midsole body, a sliding member and a driving member. The midsole body is provided with a sliding member and a driving member. The sliding member has rigidity and extends in the front-to-back direction. When the sliding member extends in the front-to-back direction so that it is located at the front end of the midsole body, it can bend together with the bending of the midsole body. The sliding member has rigidity so that when it bends together with the midsole body, the bending resistance of the midsole body is enhanced, thereby improving the bending resistance of the sole. The driving member drives the sliding member to slide in the front-to-back direction relative to the midsole body. When the driving member drives the sliding member to slide forward to the front end of the midsole body, the sliding member bends together with the bending of the midsole body, thereby enhancing the bending resistance of the midsole. When the driving member drives the sliding member to slide backward to the rear end of the midsole body, the sliding member does not bend together with the bending of the midsole body, thereby reducing the bending resistance of the midsole. Compared with the usual method of adding an immovable rigid member to the midsole body to improve the bending resistance of the sole, or manually adjusting the position of the rigid member in the midsole body to change the bending resistance of the sole, the adjustment of the bending resistance of the sole provided by the present invention is more convenient.

[0018] The first sensor acquires brain electrical signals, and the second sensor acquires masseter electrical signals. The signal processor processes the collected brain electrical signals and masseter electrical signals into EEG characteristic values ​​and myoelectric characteristic values, respectively. The controller compares the EEG characteristic values ​​with the EEG threshold value and the myoelectric characteristic values ​​with the myoelectric threshold value, and determines the state of the human body according to the comparison result, and then controls the driving member to drive the sliding member to slide forward or backward according to the state of the human body. Usually, the position of the sliding member is adjusted manually or by a mechanical switch. The present invention provides an EEG intelligent control system, which controls the sliding member to slide forward or backward through EEG intelligence. When the EEG control system determines that the human body is in a tense state, the driving member is controlled to drive the sliding member to slide forward. When the sliding member is located at the front end of the midsole body, it will bend with the bending of the midsole body, thereby enhancing the bending resistance of the sole. When the EEG control system determines that the human body is in a relaxed state, the driving member is controlled to drive the sliding member to slide backward. When the sliding member is located at the rear end of the midsole body, the bending resistance of the sole is reduced. The anti-bending property of the sole is adjusted through the EEG control system, freeing the user's hands, so that the user can adjust the anti-bending property of the sole without stopping the hand movement. The intelligent adjustment method improves the user experience. During intense exercise, the human body is usually in a tense state. Intense exercise requires the sole to provide stronger anti-bending property, which helps the wearer to run, jump and other exercises. The design of determining that the human body is in a tense state by clenching teeth and then enhancing the anti-bending property of the sole is in line with the design concept of the anti-bending property of the sole. When the human body is relaxed, the brain is usually in a relaxed state. In this state, the sole needs to provide better energy absorption, shock absorption and other functions so that the wearer can walk comfortably. The design of reducing the anti-bending property of the sole by determining that the human body is in a relaxed state through EEG also conforms to the design concept of the anti-bending property of the sole.

[0019] 2. The basis for the control system to determine the state of the human body: When the myoelectric characteristic value is greater than the myoelectric threshold, it is determined 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 myoelectric threshold is the myoelectric characteristic value of the masseter muscle when clenching teeth. When the myoelectric characteristic value compared by the controller is greater than the myoelectric threshold, it means that the human body is clenching its teeth and reaches a preset degree, that is, the human body is in a state of tension. The EEG threshold is the EEG characteristic value when the human body is in a relaxed state. When the EEG characteristic value compared by the controller is greater than the EEG threshold and the myoelectric characteristic value is less than the myoelectric threshold, it is determined that the human body is in a relaxed state. The above comparison can determine the state of the human body, and the bending resistance of the sole can be intelligently adjusted according to the state of the human body.

[0020] 3. The driving part uses a motor, which drives the sliding part to slide forward or backward by the forward or reverse rotation of the motor. The driving part using a motor is more convenient than the commonly used manual adjustment. At the same time, the controller can control the forward or reverse rotation of the driving motor to adjust the bending stiffness of the sole according to the comparison results of the EEG and EMG characteristic values ​​with the threshold.

[0021] 4. The first sensor and the second sensor are used to collect EEG signals and EMG signals and need to be attached to the skin of the corresponding area of ​​the head. The first sensor and the second sensor are both installed on a wearable headband, which is easy to carry and allows the first sensor and the second sensor to be more conveniently attached to the head skin.

[0022] 5. The signal processor and controller are placed in the mobile terminal, which can be easily carried. The mobile terminal can set the EEG threshold and the EMG threshold. The EEG signals and the EMG signals will vary with different human bodies. By setting the EEG threshold and the EMG threshold, the state of the human body can be determined more accurately.

[0023] 6. EEG signals and EMG signals will be affected by the environment. When the environmental influence makes the comparison results between the EEG characteristic value and the EEG threshold and the EMG characteristic value and the EMG threshold unable to accurately determine the state of the human body, the forward and backward buttons set on the mobile terminal can be used to control the drive component and adjust the bending resistance of the sole, so that the control system can adapt to more usage environments.

[0024] 7. The sliding member slides in the midsole body along the front-rear direction, and the slide groove provides a channel for the sliding member to slide in the front-rear direction, and the slide groove can make the sliding of the sliding member smoother.

[0025] 8. The cable connects the two ends of the sliding member and extends out of the slide slot to connect with the driving member. The driving member drives the sliding member to slide in the slide slot in the front-back direction by retracting and releasing the cable. The sliding member can be driven to slide in the front-back direction by retracting and releasing the cable. The cable itself is light in weight, which reduces the weight and production cost of the sole.

[0026] 9. The sliding part is made of carbon fiber material, which is light in weight and can provide rigidity to the sole, and can also provide a boosting effect to the user when it recovers its deformation.

[0027] 10. In a shoe, the above-mentioned sole bending resistance control system is combined with other components of the shoe to form a complete shoe structure. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0040] See also Figure 1 , Figure 1 The figure shows a schematic diagram of the structure of the left shoe midsole provided by this embodiment when viewed from above. Figure 2 The wearable headband provided in this embodiment is shown. Figure 3 A schematic diagram of a sole bending resistance control system provided in this embodiment is shown.

[0041] Figure 1The provided left foot midsole bottom view is a directional identification based on the orientation of the sole, and the orientation of the sole from the part in contact with the ground to the part in contact with the sole of the foot is the top view. The shoe midsole includes a midsole body 10, a sliding member 1, and a driving member 2. The sliding member 1 and the driving member 2 are both mounted on the midsole body 10. The sliding member 1 has rigidity and extends in the front-to-back direction. The above-mentioned front-to-back direction is a directional identification based on the orientation of the sole of the foot, and the orientation from the front toe of the sole of the foot to the rear heel is the front-to-back direction. When the shoe is used, it is mainly bent at the forefoot portion, and the bending resistance of the sole mainly depends on the bending resistance of the forefoot portion of the midsole body 10. When the sliding member 1 is located at the forefoot portion of the midsole body 10, the midsole body 10 bends and drives the sliding member 1 to bend together. The sliding member 1 uses a carbon fiber material with high rigidity. When the sliding member 1 bends together with the midsole body 10, the bending resistance of the sole is enhanced. The length of the slider 1 extending in the front-to-back direction must at least reach the point where when the slider 1 is located at the forefoot portion 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 portion of the midsole body 10, the front end of the slider 1 is located in the toe corresponding area of ​​the midsole body 10, and the rear end of the slider 1 is located in the arch corresponding area of ​​the midsole body 10. The slider 1 can disperse the force to various parts of the sole by using this length. The driving member 2 drives the slider 1 to slide in the front-to-back direction relative to the midsole body 10. In this embodiment, the driving member 2 drives the slider 1 to slide in the front-to-back direction, thereby changing its relative position in the midsole body 10 in the front-to-back direction, thereby adjusting the bending resistance of the sole. The sliding member 1 slides forward to the front end of the midsole body 10, that is, the sliding member 1 is located at the forefoot part of the midsole body 10, at this time, the bending resistance of the sole is increased; the sliding member 1 slides backward to the rear end of the midsole body 10, that is, the sliding member 1 is not located at the forefoot part of the midsole body 10, at this time, the bending resistance of the sole is reduced.

[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 position corresponding to the brain area of ​​the head to obtain brain electrical signals, and the second sensor 52 is installed at a position corresponding to the masseter muscle of the head to obtain masseter muscle electrical signals. The electrical signals existing in the human body are a reflection of normal physiological activities. Whether the human body is at rest or in motion, there will be bioelectric signals closely related to life activities. EEG signals are generated by brain neuron activities, contain a large amount of electrophysiological activity information of brain nerve cells, and reflect human thinking activities. The prior art can determine the state of the human body and the degree of the state by processing and analyzing the EEG signals of various frequency bands generated by brain nerve cells. In this embodiment, whether the human body is in a relaxed state and the degree of the relaxed state are determined by processing and analyzing the EEG signals of various frequency bands. The first sensor 51 is provided with a collection electrode attached to the skin, which is used to obtain brain electrical signals of various frequency bands. Myoelectric signals are bioelectric signals generated by muscle activities, which contain relevant information about limb activities. The amplitude and density of myoelectric signals will change with the movement of muscles. The prior art can determine the movement state of the muscle by processing and analyzing the amplitude and density of the electromyographic signal. When the force used by the human body to clench the teeth is different, the amplitude and density of the electromyographic signal of the masseter muscle will be different. In this embodiment, the action of clenching teeth represents that the human body is in a tense state. The second sensor 52 is provided with a collection electrode attached to the skin, which is used to obtain the electromyographic signal of the masseter muscle. The electroencephalogram signal and the electromyographic signal are weak, and the collection electrode is close to the part where the signal needs to be collected, which can reduce the attenuation of the electroencephalogram and the electromyographic signal due to the long transmission distance, and can also reduce the interference of other signals. The signal processor signal connects the first sensor 51 and the second sensor 52, and processes the brain electrical signal and the masseter electrical signal into electroencephalogram characteristic values ​​and electromyographic characteristic values ​​respectively. The first sensor 51 and the second sensor 52 collect the electroencephalogram signal and the electromyographic signal, and transmit the electroencephalogram signal and the electromyographic signal to the signal processor via Bluetooth. The signal processor filters the collected EEG signals and EMG signals, removes noise interference, and then uses the EEG signal processing algorithm to analyze the EEG signals of each frequency band in the processed brain electrical signals and converts them into EEG characteristic values; the EMG processing algorithm is used to analyze the amplitude and density of the processed masseter muscle electrical signals and convert them into EMG characteristic values. The EEG characteristic values ​​and EMG characteristic values ​​are digital signals, and converting the EEG signals and EMG signals into digital signals facilitates subsequent analysis and processing.

[0043] The controller is connected to the signal processor and the driver 2 using Bluetooth, and the driver 2 is controlled wirelessly. The sole does not need to be equipped with a controller and a signal processor, which reduces the weight of the sole. At the same time, the controller and the signal processor are not easily damaged, which improves the stability of the overall operation.

[0044] In this embodiment, the EEG threshold is located in the range of the EEG characteristic value obtained by processing the brain electrical signal when the brain is in a relaxed state; the EMG threshold is located in the range of the EMG characteristic value obtained by processing the masseter muscle electrical signal when the masseter muscle is in a clenching action. The signal processor transmits the processed EEG characteristic value and the EMG characteristic value to the controller, and the controller compares the EEG characteristic value with the EEG threshold and the EMG characteristic value with the EMG threshold, and determines the state of the human body according to the comparison result. By comparing the EEG characteristic value with the EEG threshold in a relaxed state, it can be determined whether the human body is in a relaxed state; by comparing the EMG characteristic value with the EMG threshold in a clenching state, it can be determined whether the human body is in a tense state. When the controller determines that the human body is in a tense state, the driving member 2 drives the sliding member 1 to slide forward to the front end of the midsole body 10 to enhance the bending resistance of the sole. When the controller determines that the human body is in a relaxed state, the driving member 2 drives the sliding member 1 to slide backward to the rear end of the midsole body 10 to reduce the bending resistance of the sole. The present invention provides a control system for users that can use EEG and EMG to intelligently adjust the bending resistance of the sole according to their own needs. When facing different sports and life scenes, the control system using EEG and EMG breaks the current traditional control methods such as manual or mechanical switch electric adjustment. When the human body is in a tense state, it means that the user is doing high-intensity exercise, and the bending resistance of the sole needs to be enhanced; when the human body is in a relaxed state, it means that the user is doing low-intensity exercise, and the bending resistance of the sole needs to be reduced to improve the comfort of the sole.

[0045] As a preferred embodiment, when the electromyographic characteristic value is greater than or equal to the electromyographic threshold, the controller determines that the human body is in a tense state. When the human body is in a tense state, it usually clenches its teeth. The greater the force of clenching the teeth, the greater the electromyographic characteristic value of the masseter muscle. When the electromyographic characteristic value is greater than or equal to the electromyographic threshold, the controller controls the driving member 2 to drive the sliding member 1 to slide forward to the front end of the midsole body 10 to increase the bending resistance of the sole. When the EEG characteristic value is greater than or equal to the EEG threshold and the electromyographic characteristic value is less than the electromyographic 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 relaxed EEG characteristic value. In this embodiment, in addition to comparing the EEG characteristic value with the EEG threshold, the electromyographic characteristic value and the electromyographic threshold are also compared to determine whether the human body is in a relaxed state, and the EEG comparison results and the electromyographic comparison results are combined to determine. 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, and the controller controls the driver 2 to drive the sliding member 1 to slide backward to the rear end of the midsole body 10, thereby reducing the bending resistance 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, and the controller controls the driver 2 to drive the sliding member 1 to slide forward to the front end of the midsole body 10, thereby increasing the bending resistance of the sole. When the EEG characteristic value is less than the EEG threshold and the EMG characteristic value is less than the EMG threshold, the controller does not control the driver 2.

[0046] The prior art can determine the state of relaxation and the degree of relaxation of the human body by processing and analyzing the EEG signals of various frequency bands generated by brain nerve cells, and can also determine the state of concentration and the degree of concentration of the human body. In other embodiments, the EEG signal is converted into an EEG relaxation characteristic value and an EEG concentration characteristic value after processing and analysis, and the controller compares the electromyographic characteristic value with the electromyographic threshold, the EEG relaxation characteristic value with the electromyographic relaxation threshold, and the EEG concentration characteristic value with the electromyographic concentration threshold. When the electromyographic characteristic value is greater than or equal to the electromyographic threshold, the controller controls the driving member 2 to drive the sliding member 1 to slide forward to the front end of the midsole body 10 to increase the bending resistance of the sole. When the electromyographic relaxation characteristic value is greater than or equal to the electromyographic relaxation threshold, the electromyographic concentration characteristic value is greater than or equal to the electromyographic concentration threshold, and any of the above 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 state or a concentrated state. When the human body is in a relaxed state or a concentrated state, the controller controls the driving member 2 to drive the sliding member 1 to slide backward to the rear end of the midsole body 10 to reduce the bending resistance of the sole.

[0047] As a preferred embodiment, the driving member 2 uses a motor, and the motor drives the sliding member 1 to slide forward by forward or reverse rotation to increase the bending resistance of the sole or slide backward to reduce the bending resistance of the sole. The increase or decrease of the bending resistance of the sole is achieved by the forward or reverse rotation of the motor, making the adjustment method more convenient. In the present embodiment, the driving member 2 is located above the sliding member 1. The above is the direction identification based on the direction of the sole, and the upper and lower directions of the sole from the part in contact with the sole to the part in contact with the ground are the upper and lower directions. The driving member 2 is located above the sliding member 1, that is, the driving member 2 is closer to the sole than the sliding member 1. The driving member 2 is accommodated in a hard shell and installed in the part of the midsole body 10 corresponding to the arch of the foot. Due to the physiological characteristics of the foot, this part has a larger space for accommodating the driving member 2 relative to other parts of the sole. At the same time, the force on this part is smaller than that on other parts of the sole, and the driving member 2 is less likely to be damaged.

[0048] As a preferred embodiment, the first sensor 51 and the second sensor 52 are placed in a wearable headband 50. The first sensor 51 is installed at the part of the headband 50 corresponding to the forehead, and is used to collect brain electrical signals; the second sensor 52 is installed at the part of the headband 50 corresponding to the back of the ear, and is used to collect masseter muscle electrical signals. The first sensor 51 and the second sensor 52 are attached to the part where the signal is to be collected, reducing the transmission distance of the EEG signal and the EMG signal, and avoiding the signal reduction due to the long transmission distance. The parts of the first sensor 51 and the second sensor 52 that contact the head skin are both metal, which is conducive to the conduction of the signal. A signal module, a battery module, etc. are also provided inside the headband 50. The headband 50 is easy to wear and comfortable for users to use, and the EEG signal and the EMG signal can be collected and transmitted synchronously.

[0049] Preferably, the signal processor and the controller are placed in the mobile terminal, and the EEG threshold and the EMG threshold can be set using the mobile terminal. In this embodiment, the mobile terminal uses a mobile phone, which integrates a signal processor, a controller, and a transmission module. The EEG signals and EMG signals collected by the first sensor 51 and the second sensor 52 are transmitted to the APP of the mobile phone via Bluetooth. The APP of the mobile phone converts the EEG signals and the EMG signals into EEG characteristic values ​​and EMG characteristic values, and then compares the EEG characteristic values ​​with the EEG threshold and the EMG characteristic values ​​with the EMG threshold, and determines whether the human body is in a tense state or a relaxed state according to the comparison results. According to different human body states, the driving member 2 is controlled by the Bluetooth module of the mobile phone to drive the sliding member 1 to slide forward or backward. The EEG threshold and the EMG threshold can be set through the APP of the mobile phone. In different relaxation states of human bodies, the EEG characteristic values ​​obtained by processing the EEG signals of each frequency band of the brain will be different. When different human bodies perform tooth-gripping movements, the amplitude and density of the masseter muscle electric signal will be different after processing the EMG characteristic values. Different settings are made for the EEG threshold and the EMG threshold, so that the comparison results of the EEG characteristic value and the EEG threshold and the EMG characteristic value and the EMG threshold can more accurately determine the user's state. In use, if the EMG characteristic value is greater than or equal to the EMG threshold in a very short time, it is judged as a tense state; if the EEG characteristic value is greater than or equal to the EEG threshold in a very short time, and the EMG characteristic value is less than or equal to the EMG threshold, it is judged as a relaxed state, which will cause the controller to mistakenly determine the state of the human body. In this embodiment, the APP of the mobile phone can set the duration of the signal characteristic value. For example, the signal duration is set to 3 seconds. When the EMG characteristic value is greater than or equal to the EMG threshold and lasts for more than 3 seconds, the controller determines that the human body is in a tense state; when the EEG characteristic value is greater than or equal to the EEG threshold and lasts for more than 3 seconds, and the EMG characteristic value is less than or equal to the EMG threshold, the controller determines that the human body is in a relaxed state. Setting the signal duration can more accurately determine the state of the human body.

[0050] Preferably, the mobile terminal is provided with a forward button and a backward button. When in use, EEG signals and electromyographic signals may be interfered by electromagnetic and noise in the surrounding environment, so that the collected EEG signals and electromyographic signals cannot accurately determine the user's state. In this embodiment, the mobile phone APP is provided with a forward button and a backward button for controlling the driver 2. By pressing the forward button, the mobile terminal controls the driver 2 to drive the sliding member 1 to slide forward, thereby enhancing the bending resistance of the sole; by pressing the backward button, the mobile terminal controls the driver 2 to drive the sliding member 1 to slide backward, thereby reducing the bending resistance of the sole. By using the forward button and the backward button, the sole bending resistance control system can be adapted to more usage environments.

[0051] Preferably, the midsole body 10 is provided with a slide groove 3 extending in the front-to-back direction, and the sliding member 1 slides in the slide groove 3 in the front-to-back direction. The midsole body 10 is provided with a cable 4, and the cable 4 connects the two ends of the sliding member 1 and extends out of the slide groove 3 to be connected with the driving member 2. The driving member 2 drives the sliding member 1 to slide in the slide groove 3 in the front-to-back direction by retracting and releasing the cable 4. The slide groove 3 extending in the front-to-back direction facilitates the sliding member 1 to slide in the front-to-back direction in the midsole body 10. In this embodiment, the midsole body 10 is provided with four slide grooves 3, and the four slide grooves 3 are arranged in the left-to-right direction. Each slide groove 3 is provided with a sliding member 1, and the two ends of each sliding member 1 are respectively connected to the cable 4. The above-mentioned left-right direction is a direction marking based on the orientation of the sole of the foot. Figure 1 It is a schematic diagram of the bottom of the left shoe from top to bottom, and the direction from the thumb to the little finger is the left-right direction. The four chute 3 is arranged in the left-right direction, which does not mean that the four chute 3 should be parallel to each other. The arrangement of the four chute 3 can not affect the sliding of the sliding member 1 and the cable 4 contained therein. The cable 4 connects the two ends of each sliding member 1 and extends out of the chute 3 to connect with the driving member 2. In this embodiment, the driving member 2 pulls the four cables 4 at the same time, that is, drives the four sliding members 1 to slide forward or backward at the same time. A conduit can also be arranged in the chute 3, and the conduit is fixedly connected to the midsole body 10. The hardness of the sliding member 1 and the cable 4 is usually greater than that of the midsole body 10, and the sliding of the sliding member 1 and the cable 4 in the midsole body 10 is easy to damage the midsole body 10. By arranging a conduit in the midsole body 10, the sliding member 1 and the cable 4 are allowed to slide in the conduit, and the midsole body 10 is better protected. It is also possible to drive the sliding member 1 to slide forward or backward in a manner other than the cable 4 driving the sliding member 1.

[0052] In addition, the present invention also provides a shoe comprising the above-mentioned sole anti-bending system.

[0053] The present invention provides a sole bending resistance control system and a shoe, comprising a shoe midsole, a signal processing module and a controller. The shoe midsole comprises: a midsole body 10, a sliding member 1 and a driving member 2. The sliding member 1 and the driving member 2 are both mounted on the midsole body 10. The sliding member 1 is made of carbon fiber material and extends in the front-to-back direction. When the sliding member 1 is located at the forefoot portion of the midsole body 10, it can be bent along with the bending of the midsole body 10. The bending resistance of the sliding member 1 is greater than that of the midsole body 10. When the sliding member 1 is bent along with the midsole body 10, the bending resistance of the midsole body 10 is enhanced, thereby improving the bending resistance of the sole. The driving member 2 drives the sliding member 1 to slide in the midsole body 10 along the front-to-back direction. When the sliding member 1 slides to the front end of the midsole body 10, it is also located at the forefoot portion. At this time, the bending resistance of the sole is enhanced; when the sliding member 1 slides to the rear end of the midsole body 10, it is not located at the forefoot portion. At this time, the bending resistance of the sole is reduced. The signal processing module includes a wearable headband 50, and a first sensor 51 is installed at the forehead corresponding to the headband, which is used to obtain brain electrical signals; and a second sensor 52 is installed at the corresponding part behind the ear, which is used to obtain masseter electrical signals. The first sensor 51 and the second sensor 52 transmit the collected EEG signals and electromyographic signals to the signal processor, and the signal processor filters the EEG signals and electromyographic signals, removes interference such as noise, and processes the EEG signals of each frequency band in the EEG signals into EEG characteristic values ​​through an algorithm, and processes the electromyographic signals into electromyographic characteristic values ​​according to their amplitude and density. The EEG characteristic values ​​and electromyographic characteristic values ​​are digital signals, and the electrical signals are converted into digital signals to facilitate subsequent comparison and application. After the signal processor processes the EEG signals and electromyographic signals into EEG characteristic values ​​and electromyographic characteristic values, it transmits them to the controller. The controller compares the EEG characteristic values ​​with the EEG threshold and the electromyographic characteristic values ​​with the electromyographic threshold, and determines the human body state according to the comparison results. When the electromyographic characteristic value is greater than the electromyographic threshold, it is determined that the human body is in a tense state, and the controller controls the driving member 2 to drive the sliding member 1 to slide forward, thereby increasing the bending resistance of the sole; when the electroencephalogram characteristic value is greater than the electroencephalogram threshold and the electromyographic characteristic value is less than the electromyographic threshold, it is determined that the human body is in a relaxed state, and the controller controls the driving member 2 to drive the sliding member 1 to slide backward, thereby reducing the bending resistance of the sole.
