Description

Technical Field

[0001] This application relates to the field of footwear technology, specifically to a control system that can adjust the bending stiffness of the sole. Background Technology

[0002] The flexural stiffness of a shoe sole is typically a fixed value after manufacturing. However, users have different needs for sole flexural stiffness depending on the type of activity and wearing scenario. During high-intensity basketball games, increased forefoot flexural stiffness improves performance in jumping and changing direction; conversely, during low-intensity training, games, or everyday wear, reduced forefoot flexural stiffness enhances comfort. Therefore, users have varying needs for sole flexural stiffness in the same pair of shoes under different activity conditions. A shoe sole consists of an insole, midsole, and outsole. The insole provides sweat absorption and reduces foot friction, while the outsole provides slip resistance and abrasion resistance. The midsole, located between the insole and outsole, provides shock absorption, energy absorption, and rebound. The sole flexural stiffness primarily depends on the midsole's flexural stiffness.

[0003] To address the aforementioned needs, this utility model provides a shoe sole with adjustable bending stiffness, which adjusts the bending stiffness of the sole by adjusting the relative position of the midsole rigid component and the midsole. While this utility model fulfills the requirement of adjustable sole bending stiffness, the adjustment method 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 an intelligent control system for adjusting the bending stiffness of the shoe sole.

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

[0006] A control system for adjusting the stiffness of a shoe sole includes a shoe sole and a controller. The shoe sole includes a midsole body, a slider, and a drive component. The slider is disposed within the midsole body and extends in a front-to-back direction. The slider is driven by the drive component to slide relative to the midsole body in the front-to-back direction to adjust the bending stiffness of the shoe sole. The controller is disposed in the hand and includes a tension sensor and a signal generator. The tension sensor is used to sense the stretching or contraction of the skin of the fingers, and the signal generator controls the drive component to drive the slider to slide forward or backward.

[0007] Furthermore, the tensile sensor is a resistive tensile sensor, whose resistance value changes with the deformation of its stretching or contraction.

[0008] Furthermore, the controller compares the resistance value of the stretch sensor with the stretch threshold and the resistance value of the stretch sensor with the contraction threshold, and controls the driving component based on the comparison results: when the resistance value of the stretch sensor is greater than or equal to the stretch threshold, the signal generator controls the driving component to drive the slider to slide forward; when the resistance value of the stretch sensor is less than the contraction threshold, the signal generator controls the driving component to drive the slider to slide backward.

[0009] Furthermore, there are several stretch sensors, all used to sense the stretching or contraction of the finger skin.

[0010] Furthermore, the driving component is a motor, which drives the sliding component to slide forward or backward by rotating forward or in reverse.

[0011] Furthermore, the midsole body is provided with a sliding groove extending in the front-to-back direction, and the sliding member is accommodated in the sliding groove.

[0012] 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.

[0013] Furthermore, the sliding component is made of carbon fiber.

[0014] Furthermore, the controller is placed on the wearable, and the stretch sensor is used to sense the stretching or contraction of the wearable.

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

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

[0017] 1. The sole consists of an insole, midsole, and outsole. The flexural stiffness of the sole primarily depends on the flexural stiffness of the midsole. A slider is installed within the midsole body, extending forward and backward. When the slider is located at the forefoot of the midsole body, the bending of the midsole body causes the slider to bend, increasing the flexural stiffness of the sole. The slider is driven by a drive component to slide relative to the midsole body in the forward and backward direction. The flexural stiffness of the sole varies depending on the location of the slider at different points along the forward and backward direction. When the slider slides forward to the forefoot of the midsole body, the flexural stiffness increases; when it slides backward to a point not located at the forefoot of the midsole body, the flexural stiffness decreases. The drive component adjusts the flexural stiffness of the sole by driving the slider forward and backward. The controller includes a tension sensor and a signal generator. The tension sensor detects the stretching or contraction of the finger skin, and the signal generator controls the drive component to move the slider forward or backward. By sensing the stretching or contraction of the finger's skin, a slider is driven forward to increase the flexural stiffness of the shoe sole, and backward to decrease it. Previously, the actuator was controlled manually or by a mechanical switch; now, the stretch sensor provides a more intelligent and faster control.

[0018] 2. The resistance of the tension sensor changes with its stretching or contraction deformation. The tension sensor is attached to the skin; when the body moves, the relative position between the skin and the body shifts, causing the tension sensor to stretch or contract, thus changing its resistance. By sensing the body's movement state through the tension sensor, the bending stiffness of the shoe sole is intelligently adjusted, improving the user experience.

[0019] 3. The controller compares the resistance value of the stretch sensor with the stretch threshold and the resistance value of the stretch sensor with the contraction threshold. When the stretch sensor stretches, its resistance increases. When its resistance value is greater than the stretch threshold, the controller controls the drive component to drive the slider forward, increasing the bending stiffness of the sole. When the stretch sensor contracts, its resistance decreases. When its resistance value is less than the contraction threshold, the controller controls the drive component to drive the slider backward, reducing the bending stiffness of the sole. By comparing the resistance value of the stretch sensor with the threshold, the controller intelligently analyzes the human body's motion state and adjusts the bending stiffness of the sole to suit that motion state, providing an intelligent and personalized adjustment method.

[0020] 4. Several tension sensors are used to sense the stretching or contraction of the finger skin. Using different numbers of tension sensors can improve the accuracy of adjusting the bending stiffness of the shoe sole. Different trigger gestures can also be set to increase the personalization of the adjustment method. The signal generator only controls the drive component when the resistance values ​​of several tension sensors are simultaneously greater than the stretching threshold or simultaneously less than the contraction threshold, which can avoid false triggering of the drive component and maintain the accuracy of the adjustment.

[0021] 5. The motor rotates forward or backward, causing the slider to slide forward or backward. Forward rotation corresponds to one direction of movement for the slider, while reverse rotation corresponds to the opposite direction. Using a motor to drive the slider allows a signal generator to control the motor to produce different rotation directions, adjusting the bending stiffness of the shoe sole. Compared to manually driving the slider, this saves manpower and improves the user experience.

[0022] 6. The midsole body is provided with a groove extending in the front-to-back direction, and the slider is adapted to slide in the groove in the front-to-back direction. The groove provides a sliding path for the slider to slide in the front-to-back direction, so that the slider can slide smoothly.

[0023] 7. The cable is fixed to both ends of the slider and extends out of the groove to connect with the drive component. The drive component drives the cable to move the slider in a back-and-forth motion to adjust the bending stiffness of the sole. The drive component moves the slider in the back-and-forth direction within the groove by retracting or releasing the cable. Retracting the cable at the front of the slider and releasing the cable at the rear of the slider drives the slider forward, increasing the bending stiffness of the sole; retracting the cable at the rear of the slider and releasing the cable at the front of the slider drives the slider backward, reducing the bending stiffness of the sole. Using a cable to drive the slider reduces production costs and makes the overall operation more stable.

[0024] 8. The sliding component is made of carbon fiber, which is lightweight and has high rigidity. It also provides a boost to the user when the sliding component recovers from deformation.

[0025] 9. The controller is placed on the wearable device. When the human body uses the device, it causes it to stretch or contract. A stretch sensor detects the stretching or contraction of the wearable device and controls the actuators via a signal generator. Placing the controller on the wearable device makes the control system more comfortable and convenient for the user compared to having it attached to the skin.

[0026] 10. Shoes manufactured using the above technical solutions can have their motors controlled by a controller to intelligently adjust the bending stiffness of the sole. Attached Figure Description

[0035] Unless otherwise specified, the terms “comprising,” “having,” and variations thereof in the claims and description shall mean “including but not limited to.”

[0036] 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.

[0037] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings.

[0038] See Figure 1 , Figure 1 The sole of a shoe is shown in this embodiment, which is part of a control system for adjusting the bending stiffness of the sole. Figure 2 The controller of a control system for adjusting the stiffness of a shoe sole provided in this embodiment is shown.

[0039] Figure 1 This is a bottom view of the shoe sole. The orientation of the sole is determined by its direction, measured from the point of contact with the ground to the point of contact with the foot. Figure 1This is a bottom view of the left shoe sole. The sole comprises a midsole body 10, a slider 1, and a drive component 2. The slider 1 is located within the midsole body 10 and extends in a front-to-back direction. The front-to-back direction is based on the orientation of the foot, specifically the direction from the toes to the heel. During use, the shoe primarily bends at the forefoot, and the sole's bending stiffness depends mainly on this area. The slider 1 extends in the front-to-back direction; when it is located at the forefoot of the midsole body 10, bending of the midsole body 10 causes the slider 1 to bend. The slider 1 is made of carbon fiber, a material known for its high rigidity. The bending of the midsole body 10, which in turn causes the slider 1 to bend, increases the bending stiffness of the midsole body 10, thereby increasing the overall bending stiffness of the sole. The drive component 2 drives the slider 1 to slide relative to the midsole body 10 in the front-to-back direction to adjust the sole's bending stiffness. If the slider 1 cannot slide in the front-to-back direction and can only be fixed at the forefoot of the midsole body 10, then although the slider 1 increases the flexural stiffness of the midsole body 10, it cannot adjust the flexural stiffness of the midsole body 10. The driving component 2 drives the slider 1 to slide relative to the midsole body 10 in the front-to-back direction. When the slider 1 slides forward to the forefoot of the midsole body 10, the flexural stiffness of the sole increases; when the slider 1 slides backward to a position not located at the forefoot of the midsole body 10, the flexural stiffness of the sole decreases. In this embodiment, sliding the slider 1 forward increases the flexural stiffness of the sole, and sliding the slider 1 backward decreases the flexural stiffness of the sole. By changing the relative position of the slider 1 with respect to the midsole body 10 in the front-to-back direction through the driving component 2, the flexural stiffness of the sole can be adjusted, which also simplifies the operation of adjusting the flexural stiffness of the sole.

[0040] The controller 100 is placed on the hand and includes a stretch sensor 110 and a signal generator 120. The stretch sensor 110 senses the stretching or contraction of the finger skin and controls the drive member 2 to drive the slider 1 to slide forward or backward via the signal generator 120. The "forward" and "backward" directions are based on the orientation of the sole of the foot. The orientation from the toe to the heel is the front-back direction; sliding towards the toe is forward sliding, and sliding towards the heel is backward sliding. When the finger moves, the relative position between the finger skins shifts, specifically manifested as stretching or contraction. The stretch sensor 110 is attached to the finger skin. When the finger skin stretches, it stretches the stretch sensor 110 attached to its surface; when the finger skin contracts, it contracts the stretch sensor 110 attached to its surface. In this embodiment, the stretch sensor 110 is a resistive stretch sensor, and its resistance value changes according to its stretching or contraction deformation. When the stretch sensor 110 stretches, its resistance value increases; when the stretch sensor 110 contracts, its resistance value decreases. The resistive tensile sensor 110 is existing technology; its resistance increases when stretched and decreases when contracted, a principle that will not be elaborated upon here. The controller 100 compares the resistance value of the tensile sensor 110 with a resistance threshold, and based on the comparison result, controls the drive component 2 via the signal generator 120 to drive the slider 1 to slide forward or backward. In this embodiment, the tensile sensor 110 controls the relative position of the slider 1 in the midsole body 10 along the front-back direction to adjust the bending stiffness of the sole, improving the user experience through intelligent adjustment.

[0041] In this embodiment, the stretch sensor 110 is attached to the skin of the fingers on the back of the hand along the finger extension direction. When the wearer makes a fist, the finger bending action stretches the skin of the fingers on the back of the hand, which in turn stretches the stretch sensor 110 attached to its surface, increasing its resistance. When the resistance of the stretch sensor 110 is greater than or equal to a stretch threshold, the signal generator 120 controls the drive unit 2 to drive the slider 1 to slide forward, increasing the bending stiffness of the sole. When the wearer straightens their fingers, the skin contracts, causing the stretch sensor 110 attached to its surface to contract, decreasing its resistance. When the resistance of the stretch sensor 110 is less than a contraction threshold, the signal generator 120 controls the drive unit 2 to drive the slider 1 to slide backward, reducing the bending stiffness of the sole. When the stretch threshold is greater than the contraction threshold, the resistance of the stretch sensor 110 is greater than or equal to the contraction threshold; when it is less than the stretch threshold, the controller does not control the drive unit 2. When you clench your fist and bend your fingers, the flexural stiffness of the shoe sole increases; when you straighten your fingers, the flexural stiffness of the shoe sole decreases. This matches the user's usage scenario: clenching your fist represents passion, requiring the shoe sole to increase flexural stiffness to enhance the user's explosive power; straightening your fingers represents calmness, requiring the shoe sole to reduce flexural stiffness to provide comfort.

[0042] In this embodiment, four tension sensors 110 are used, corresponding to the index, middle, ring, and little fingers, respectively, and are attached to the skin of the fingers on the back of the hand along the extension direction of each finger. When making a fist, all four fingers bend simultaneously. When the resistance values ​​of the four tension sensors 110 are simultaneously greater than the tension threshold, the signal generator 120 controls the drive component 2 to drive the slider 1 to slide forward, increasing the bending stiffness of the sole. When all four fingers straighten simultaneously, when the resistance values ​​of the four tension sensors 110 are simultaneously less than the contraction threshold, the signal generator 120 controls the drive component 2 to drive the slider 1 to slide backward, reducing the bending stiffness of the sole. Using four sensors 110 can better match the fist-making and relaxing actions. The controller 100 compares the resistance values ​​of the four tension sensors 110 simultaneously. Only when the four resistance values ​​are simultaneously greater than or equal to the tension threshold or simultaneously less than the contraction threshold will the controller 100 control the drive component 2 to drive the slider 1 to slide in the forward and backward direction. This can avoid users accidentally triggering the control system and improve the accuracy of operation. In other embodiments, other numbers of tension sensors 110 can also be used, and different triggering methods can be designed. The stretch sensor 110 can also be attached to other parts of the body. The stretching or contraction of the skin in other parts of the body causes the stretch sensor 110 to stretch or contract, controlling the drive unit 2 to drive the slider 1 to slide forward or backward. In other embodiments, the controller 100 can be placed on the wearable device, and the stretch sensor 110 is used to sense the stretching or contraction of the wearable device. When the user uses the wearable device, it causes the device to stretch or contract, changing the resistance value of the stretch sensor 110. The controller 100, by comparing the resistance value of the stretch sensor 110 with a stretching threshold or a contraction threshold, controls the drive unit 2 to drive the slider 1 to slide in the front-back direction, adjusting the bending stiffness of the shoe sole. In this embodiment, the controller 100 does not directly contact the skin, improving user comfort and convenience compared to attaching the sensor 110 to the user's skin.

[0043] In a preferred embodiment, the driving component 2 is a motor. The motor drives the sliding component 1 forward to increase the bending stiffness of the sole or backward to decrease it by rotating forward or backward. The driving component 2 also includes a rigid housing in which the motor is housed. A groove is provided in the arch portion of the midsole body 10, and the rigid housing of the driving component is housed in the groove and fixed to the midsole body 10. The driving component 2 also includes a battery, a Bluetooth module, etc. The driving component 2 is a bidirectional motor capable of rotating forward or backward. The signal generator 120 controls the motor to rotate forward or backward based on the comparison between the resistance value of the tension sensor 110 and a threshold value. By controlling the forward or backward rotation of the motor, the sliding component 1 is driven to slide forward or backward, intelligently adjusting the bending stiffness of the sole.

[0044] In this embodiment, the midsole body 10 is provided with a groove 3 extending in the front-to-back direction. The slider 1 slides in the groove 3 in the front-to-back direction. The groove 3 provides a channel for the slider 1 to slide, allowing the slider 1 to slide more smoothly. The midsole body 10 is also 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 and releasing the cable 4. When the drive member 2 rotates forward, it pulls the cable 4 at the front end of the slider 1 and releases the cable 4 at the rear end of the slider 1, driving the slider 1 to slide forward; when the drive member 2 rotates in reverse, it pulls the cable 4 at the rear end of the slider 1 and releases the cable 4 at the front end of the slider 1, driving the slider 1 to slide backward. Preferably, the midsole body 10 is provided with four grooves 3 arranged in the left-to-right direction. Each of the four grooves 3 is provided with a slider 1, and four cables 4 are provided to connect the two ends of the corresponding slider 1 and extend out of the groove 3, all of which are connected to the drive member 2. When the drive component 2 rotates forward, it simultaneously pulls the cables 4 at the front end of the four sliders 1 and releases the cables 4 at the rear end of the four sliders 1, driving the four sliders 1 to slide forward simultaneously, thus enhancing the bending stiffness of the sole. When the drive component 2 rotates in reverse, it simultaneously pulls the cables 4 at the rear end of the four sliders 1 and releases the cables 4 at the front end of the four sliders 1, driving the four sliders 1 to slide backward simultaneously, thus reducing the bending stiffness of the sole. In other embodiments, the midsole body 10 is also provided with a guide tube, which is housed in the groove 3 and fixed to the midsole body 10. The sliders 1 slide in the guide tube in the front-back direction. The rigidity of the sliders 1 is greater than that of the midsole body 10, and its sliding in the groove 3 would damage the midsole body 10. The sliders 1 slide in the guide tube, preventing them from directly contacting the midsole body 10, thus making the midsole body 10 less prone to damage and improving the overall stability of operation.

[0045] In addition, this utility model also provides a shoe that includes the above-mentioned control system for adjusting the bending stiffness of the sole.

[0046] This invention provides a control system for adjusting the bending stiffness of a shoe sole. A slider 1 is used to increase the bending stiffness of the sole. The slider 1 extends in the front-to-back direction and is driven by a drive 2 to slide relative to the midsole body 10 in the front-to-back direction to adjust the bending stiffness of the sole. The slider 1 is typically made of carbon fiber, which not only improves the stiffness of the sole but also provides a propulsive effect when the slider 1 recovers from deformation. When the slider 1 is located at the forefoot of the midsole body 10, the bending of the midsole body 10 causes the slider 1 to bend. The slider 1 has a higher rigidity than the midsole body 10, and when it bends together with the midsole body 10, it increases the bending stiffness of the midsole body 10, thereby increasing the bending stiffness of the sole. The drive 2 is a motor, which drives the slider 1 to slide in the front-to-back direction by rotating forward or reverse. By adjusting the position of the slider 1 in the front-to-back direction of the midsole body 10 using the drive 2, the bending stiffness of the sole is adjusted. When the slider 1 is located at the forefoot of the midsole body 10, the bending stiffness of the sole increases; when the slider 1 is not located at the forefoot of the midsole body 10, the bending stiffness of the sole decreases. The controller 100 is located in the hand and includes a tension sensor 110 and a signal generator 120. The tension sensor 100 is attached to the skin of the fingers on the back of the hand to sense the stretching or contraction of the finger skin. The tension sensor 110 is a resistive tension sensor; its resistance changes with the deformation of stretching or contraction, increasing during stretching and decreasing during contraction. Four tension sensors 110 are attached to the skin of the back of the hand along the finger extension direction, respectively for the index, middle, ring, and little fingers. These four tension sensors 110 can more accurately determine finger movements, reflecting the user's actual needs. When the hand makes a fist, the skin on the back of the fingers stretches, causing the four tension sensors 110 to stretch, increasing their resistance. When the resistance of the four tension sensors 110 is simultaneously greater than or equal to the stretching threshold, the signal generator 120 controls the drive unit 2 to drive the four sliders 1 to slide forward simultaneously, increasing the bending stiffness of the sole. When the hand straightens the fingers, the skin on the back of the fingers contracts, causing the four tension sensors 110 to contract, decreasing their resistance. When the resistance of the four tension sensors 110 is simultaneously less than the contraction threshold, the signal generator 120 controls the drive unit 2 to drive the four sliders 1 to slide backward simultaneously, reducing the bending stiffness of the sole.

[0047] The description of the above specification and embodiments is used to explain the scope of protection of this application, but does not constitute a limitation on the scope of protection of this application.
