Abstract
Description
Technical Field
[0001] This utility model relates to the field of smart shoe technology, and specifically to a smart anti-fall shoe sole. Background Technology
[0002] With social development and changes in population structure, the safety issues caused by falls are becoming increasingly prominent. In daily life, the elderly are a high-risk group for falls due to physiological factors such as declining physical function, weakened muscle strength, decreased balance, and slower reaction speed. According to statistics from relevant medical research institutions, about one-third of people over the age of 65 will experience a fall each year. The serious consequences of falls, such as fractures and traumatic brain injuries, not only cause great suffering to the elderly themselves, but also impose a heavy medical burden and economic pressure on their families and society.
[0003] In the field of medical rehabilitation, many patients, such as stroke patients, Parkinson's disease patients, and people with mobility impairments due to other neurological or musculoskeletal disorders, face a significantly increased risk of falls during rehabilitation or in daily life due to decreased coordination and control. Each fall can affect the rehabilitation process and even worsen the condition.
[0004] Currently, some technologies and products exist for fall prevention, but they all have certain limitations. For example, a smart anti-fall shoe [application number: CN202510007334.X] proposes a smart shoe that uses a sensor array to detect gait information, but in terms of implementing the fall prevention function, it lacks an adaptive adjustment mechanism for different environmental conditions, and its adaptability to complex and changing real-world scenarios is insufficient, resulting in an unsatisfactory fall prevention effect.
[0005] Therefore, this utility model proposes an intelligent anti-fall shoe sole. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an intelligent anti-fall sole, solving the problem that existing smart shoes lack an adaptive adjustment mechanism for different environmental conditions and are not adaptable enough to complex and ever-changing real-world scenarios.
[0007] The technical solution to achieve the above objectives is:
[0008] This invention provides an intelligent anti-fall sole, installed on the bottom of a shoe. The anti-fall sole includes: a sole body; a motion sensor module embedded in the sole body for sensing the overall posture of the sole body; two adjustable support mechanisms respectively located in the middle-rear and middle-front parts of the sole body, each adjustable support mechanism including two or more fixed ends embedded in the sole body and anti-slip studs located at the lower ends of the fixed ends, the fixed ends being distributed in two rows with gaps between them, the lower ends of the anti-slip studs extending from the bottom surface of the sole body and contacting the ground, and the extension length of the anti-slip studs being adjustable to adjust the posture of the sole body; and a control unit connected to the motion sensor module and the adjustable support mechanisms, thereby enabling the control unit to receive data information from the motion sensor module and adjust the overall posture of the sole body through the adjustable support mechanisms to prevent the user from falling.
[0009] Furthermore, it also includes a power assembly, which is fixed to the upper end of the fixed end and connected to the control unit, and the upper end of the anti-slip pin is slidably inserted into the fixed end and connected to the power assembly.
[0010] Furthermore, it also includes a limiting ring fitted on the outer surface of the fixed end to prevent the fixed end from sliding up and down.
[0011] Furthermore, the lower end of the anti-slip stud is a sharp point, and the sharp point is located entirely on the outside of the sole body.
[0012] Furthermore, the maximum diameter of the pointed end is greater than the diameter of the fixed end to prevent the pointed end from retracting into the sole body.
[0013] Furthermore, it also includes a pressure sensor array formed by two or more pressure sensors spaced apart, embedded in the sole body, for collecting pressure information from the foot; the pressure sensor array is connected to the control unit.
[0014] Furthermore, the pressure sensor array has three sensors, located in the forefoot area, arch area, and heel area of the sole body, respectively, to detect the pressure distribution in the corresponding areas of the sole, thereby determining the user's center of gravity distribution and body posture.
[0015] Furthermore, it also includes an alarm communication module embedded in the sole, which connects to the monitor's mobile phone or smartwatch, sending alarm information to the mobile phone or smartwatch when the user falls.
[0016] Furthermore, the sole itself is made of non-slip rubber.
[0017] Furthermore, the upper surface of the sole is curved, with a curvature designed to match the curvature of the human foot.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] By incorporating an adjustable support mechanism, the anti-slip studs of this mechanism contact the ground, thereby increasing the friction between the sole and the ground to achieve an anti-slip effect. Furthermore, when the user is at risk of falling, the extension length of the anti-slip studs adjusts according to the user's body posture, adjusting the posture of the sole and helping the body regain balance.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] See Figure 1This invention provides an intelligent anti-fall shoe sole, addressing the problem that existing smart shoes lack adaptive adjustment mechanisms for different environmental conditions and are insufficiently adaptable to complex and changing real-world scenarios. By incorporating an adjustable support mechanism, the anti-slip studs of this mechanism contact the ground, thereby increasing the friction between the sole and the ground to achieve an anti-slip effect. Furthermore, when the user is at risk of falling, the extension length of the anti-slip studs adjusts according to the user's body posture, adjusting the posture of the sole and thus helping the body regain balance.
[0030] The following description, in conjunction with the accompanying drawings, describes an intelligent anti-fall shoe sole according to this utility model.
[0031] See Figure 1 This image shows a top sectional view of the intelligent anti-fall shoe sole of this invention. (See also...) Figure 2 This image shows a side sectional view of the intelligent anti-fall shoe sole of this invention. (See also...) Figures 7 to 8 The diagram below shows the anti-fall design of the intelligent anti-fall shoe sole of this utility model. Figure 1 , Figure 2 , Figure 7 and Figure 8 This invention describes an intelligent anti-fall shoe sole.
[0032] like Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, this utility model discloses an intelligent anti-fall shoe sole, installed on the bottom of a shoe. The anti-fall shoe sole includes: a sole body 10; a motion sensor module 13 embedded in the sole body 10 for sensing the overall posture of the sole body 10; and two adjustable support mechanisms 15, respectively located in the middle-rear and middle-front parts of the sole body 10. Each adjustable support mechanism 15 includes two or more fixed ends 151 embedded in the sole body 10 and anti-slip studs 153 located at the lower end of each fixed end 151. The anti-slip studs 151 are arranged in two rows with gaps between them. The lower ends of the anti-slip studs 153 extend from the bottom surface of the sole body 10 and contact the ground. The extension length of the anti-slip studs 153 is adjustable to adjust the posture of the sole body 10. A control unit 11 is connected to the motion sensor module 13 and the adjustable support mechanism 15. The control unit 11 receives data from the motion sensor module 13 and adjusts the overall posture of the sole body 10 through the adjustable support mechanism 15 to prevent the user from falling. When walking on uneven ground, the control unit 11 controls the extension length of the anti-slip studs 153 so that the lower ends of the anti-slip studs 153 abut against the ground, allowing the bottom surface of the sole body 10 to conform to the ground and prevent slipping. When the control unit 11 determines that the user is at risk of falling, it controls the extension length of the anti-slip studs 153 based on the specific risk situation and human posture data, thereby adjusting the posture of the sole body 10 to help the user quickly restore body balance and achieve the effect of preventing falls.
[0033] In one embodiment of this utility model, the fixed ends 151 of each adjustable support mechanism 15 are distributed in two rows, with seven in each row, along the width direction of the sole body 10, and the fixed ends 151 of each row are aligned with each other, so that the sole body 10 can be adequately supported and prevented from slipping by the anti-slip studs 153.
[0034] Specifically, the anti-slip stud 153 is made of tungsten carbide alloy, which makes the anti-slip stud 153 harder, more wear-resistant, and increases its service life.
[0035] Specifically, the motion sensor module 13 includes a three-axis accelerometer and a three-axis gyroscope. The accelerometer can measure the acceleration changes of the sole body in the X, Y, and Z axes in real time, thereby obtaining information on the speed changes and direction changes when the human body walks or moves. The three-axis gyroscope can monitor the angular velocity and tilt angle of the sole body 10 on the three rotation axes in real time, accurately sensing changes in the human body posture, such as whether the human body is tilting or swaying.
[0036] The control unit 11 uses a high-performance microprocessor to process the data information of the motion sensor module 13 through intelligent algorithms (including gait analysis algorithms and fall risk assessment algorithms based on human biomechanics), analyzes the human gait pattern, such as stride length and stride frequency, and analyzes the overall posture of the human body through gait information, foot acceleration and angular velocity, establishes a fall risk assessment model, and judges in real time whether the human body is in a fall risk state.
[0037] In one specific embodiment, a power assembly 150 is further included, which is fixed to the upper end of the fixed end 151 and connected to the control unit 11. The upper end of the anti-slip pin 153 is slidably inserted into the fixed end 151 and connected to the power assembly 150. By providing the power assembly 150, the control unit 11 can adjust the extension length of the anti-slip pin 153 through the power assembly 11.
[0038] In a preferred embodiment, the power unit 150 is a pneumatic pump.
[0039] In another preferred embodiment, the power unit 150 is a hydraulic pump.
[0040] In one specific embodiment, a limiting ring 152 is further included, sleeved on the outer surface of the fixed end 151, to prevent the fixed end 151 from sliding up and down. The fixed end 151 is entirely embedded in the sole body 10. Since the fixed end 151 is a cylinder with the same diameter, there is a risk of it falling out of the sole body 10. By setting the limiting ring 152, the limiting ring 152 is embedded in the sole body 10. Since the diameter of the limiting ring 152 is larger than the diameter of the fixed end 151, the fixed end 151 is limited within the sole body 10 and will not slide up or down under the action of external force, thus preventing the fixed end 151 from damaging the structure of the sole body 10.
[0041] In one specific embodiment, the lower end of the anti-slip stud 154 is a sharp end, and the sharp end is entirely located on the outside of the sole body 10. By providing a sharp end, the anti-slip stud 154 has sufficient friction with the ground.
[0042] In one specific embodiment, the maximum diameter of the sharp end is greater than the diameter of the fixed end 151 to prevent the sharp end from retracting into the sole body 10.
[0043] In one specific embodiment, it also includes a pressure sensor array formed by two or more pressure sensors 12 spaced apart and embedded in the sole body 1 for collecting pressure information of the foot; the pressure sensor array is connected to the control unit 11.
[0044] In one specific embodiment, the pressure sensor array has three sensors, located in the forefoot area, arch area, and heel area of the shoe sole body 1, respectively. These sensors detect the pressure distribution in the corresponding areas of the sole, thereby determining the user's center of gravity distribution and body posture. The three pressure sensor arrays detect pressure in the forefoot, arch, and heel areas of the human foot, and the control unit 11 analyzes the data to obtain the user's center of gravity position and gait characteristics. When the pressure sensor on the right side of the sole detects an abnormally increased pressure, it is determined that the user is at risk of falling to the right; when the pressure sensor on the left side of the sole detects an abnormally increased pressure, it is determined that the user is at risk of falling to the left.
[0045] Preferably, in one embodiment of this invention, the pressure sensors 12 in the forefoot area have five rows, the pressure sensors 12 in the arch area have six rows, and the pressure sensors 12 in the heel area have five rows, with the same spacing between adjacent rows of pressure sensors 12. The pressure sensors 12 can be high-precision thin-film pressure sensors, connected to each other via flexible circuit boards, allowing the pressure sensors 12 to occupy less space within the sole body 10, avoiding impact on the comfort of the sole body 10 while still maintaining the performance of the pressure sensors 12.
[0046] Specifically, the spacing between two adjacent pressure sensors 12 is the same, thus making the distribution of pressure sensors 12 more uniform.
[0047] The two adjustable support mechanisms 15 are respectively between the pressure sensor array in the forefoot area and the pressure sensor array in the arch area, and between the pressure sensor array in the arch area and the pressure sensor array in the heel area.
[0048] In one specific embodiment, an alarm communication module 14 is also included, embedded in the sole body 10, which connects to the caregiver's mobile phone or smartwatch. When the user falls, an alarm message is sent to the mobile phone or smartwatch. The caregiver receives the user's information via their mobile phone and receives an alarm message from the user after a fall, allowing the caregiver to quickly take appropriate action. The user can regularly check their physical condition using their mobile phone or smartwatch, and the system will automatically call the caregiver and hospital in the event of a fall, ensuring prompt assistance.
[0049] The alarm communication module 14 includes a Bluetooth communication module and a wireless communication module (such as 4G and 5G). The Bluetooth communication module connects to the user's mobile phone or smartwatch, and the wireless communication module connects to the monitor's mobile phone. The user can view their gait information or other data using their mobile phone or smartwatch, and the monitor can also view it using their mobile phone. It also includes a GPS positioning module. When a person falls, the module sends alarm information and location information to the monitor's mobile phone via the wireless communication module, making it easier for the monitor to locate the fallen person. Furthermore, it includes an audible alarm device and a flashing light device. When a user is detected to be at risk of falling or has already fallen, the audible alarm module sounds an alarm, and the flashing light device flashes a light to alert those nearby to take appropriate action.
[0050] In one specific embodiment, the sole body 10 is made of anti-slip rubber. By using anti-slip rubber material to make the sole body 10, the sole body 10 has greater friction with the ground, making it more stable for the user to walk on wet surfaces and reducing the risk of falling.
[0051] Preferably, the sole body 10 is made of polyurethane or ethylene-vinyl acetate copolymer, both of which are lightweight, elastic, and wear-resistant. This ensures the durability of the sole body 10 while also providing comfort and lightness.
[0052] In one specific embodiment, the upper surface of the sole body 10 is curved, and the curvature is designed to match the curvature of the human foot. This allows the upper surface of the sole body 10 to fit more closely to the human foot, ensuring that the foot is fully supported by the sole body 10, allowing the foot to relax more, thereby improving the user's comfort.
[0053] In one embodiment, a battery is also included. The battery is connected to other components, including a control unit 11, a pressure sensor 12, a motion sensor module 13, an alarm communication module 14, and a power assembly 150.
[0054] Preferably, the pressure sensor 12 and motion sensor module 13 operate in a low-frequency sampling mode of 10Hz during normal use. When abnormal acceleration or abnormal foot pressure fluctuations are detected, they automatically switch to a high-frequency mode of 100Hz to handle unexpected situations. By enabling the pressure sensor 12 and motion sensor module 13 to use lower power consumption during normal use, the battery usage is reduced, and the overall battery life is improved.
[0055] Preferably, the battery has three charging options: 1. Wireless charging: A receiving coil is installed in the heel of the sole body 10 and connected to the battery for wireless charging via a wireless charger. 2. Wired charging: A charging port is installed in the heel of the sole body 10 and connected to the battery for charging via a compatible charger. 3. Energy recovery: Energy harvesting devices are installed in the forefoot and heel areas of the sole body 10. When the user walks, the pressure on the sole body 10 causes the internal energy harvesting devices to absorb the deformation of the sole body 10 and generate electrical energy, thereby charging the battery.
[0056] The working principle of this invention, a smart anti-fall shoe sole, will be explained in detail below.
[0057] When wearing shoes with anti-fall soles, users can connect to the alarm communication module 14 via Bluetooth using their mobile phones or smartwatches to obtain gait information and other data. The monitoring personnel can connect to the alarm communication module 14 via their own mobile phones through the communication network to observe the user's location information and gait information. After the user falls, the alarm communication module 14 will send information to the monitoring personnel.
[0058] When a user walks on an uneven surface, the pressure sensor array 12 transmits bottom pressure information to the control unit 11. The control unit 11 adjusts the extension length of the anti-slip studs 153 according to the pressure information and through the power component 150, so that the sharp end of the anti-slip studs 153 is in contact with the ground, so that the sole body 10 has sufficient support and sufficient grip, thereby achieving the functions of preventing falls and preventing slips.
[0059] In addition, when the control unit 11 determines that the user is at risk of falling, it controls the extension length of the anti-slip studs 153 according to the specific risk situation and human posture data, thereby adjusting the posture of the sole body 10 to help the user quickly restore body balance and achieve the effect of preventing falls.
[0060] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
