Description

Technical Field

[0001] The present invention relates to the technical field of intelligent shoes, and particularly refers to an intelligent anti-fall sole. Background Art

[0002] In daily life, due to the decline of physical functions in the elderly, such as weakened muscle strength, decreased balance, and slower reaction speed and other physiological factors, they become a high-risk group for falling. According to statistics from relevant medical research institutions, among the elderly over 65 years old, about one-third of them will experience a fall event every year. And the serious consequences such as fractures and craniocerebral injuries caused by falls not only bring great pain to the elderly themselves, but also impose a heavy medical burden and economic pressure on families and society.

[0003] In the field of medical rehabilitation, many patients such as stroke patients, Parkinson's disease patients, and those with limited mobility due to other nervous system or musculoskeletal system diseases. During the rehabilitation process or in daily life, due to the decline in body coordination and control ability, the risk of falling increases significantly. And each fall may affect the rehabilitation process and even lead to the deterioration of the condition.

[0004] Currently, there are already some related technologies and products in preventing falls, but they all have certain limitations. For example, an intelligent anti-fall shoe [Application No.: CN202510007334.X] proposes an intelligent shoe that uses a sensor array to detect gait information. However, in terms of realizing the anti-fall function, it lacks an adaptive adjustment mechanism for different environmental conditions and has insufficient adaptability to complex and changeable actual scenarios, resulting in an unsatisfactory anti-fall effect.

[0005] Therefore, the present invention proposes an intelligent anti-fall sole. Summary of the Invention

[0006] The purpose of the present invention is to overcome the defects of the prior art and provide an intelligent anti-fall sole to solve the problem that the existing intelligent shoes lack an adaptive adjustment mechanism for different environmental conditions and have insufficient adaptability to complex and changeable actual scenarios.

[0007] The technical solution to achieve the above purpose is as follows:

[0008] The present invention provides an intelligent anti - fall sole, which is installed at the bottom of a shoe. The anti - fall sole includes: a sole body; a motion sensor module buried in the sole body for sensing the overall posture of the sole body; two adjustable support mechanisms respectively arranged at the mid - rear part and the mid - front part of the sole body. The adjustable support mechanism includes two or more fixed ends buried in the sole body and anti - slip nails arranged at the lower ends of the fixed ends. The fixed ends are distributed in two columns and have a gap between them. The lower ends of the anti - slip nails extend out from the bottom surface of the sole body and contact the ground, and the extending length of the anti - slip nails is adjustable to adjust the posture of the sole body; and a control unit, which is connected to the motion sensor module and the adjustable support mechanism, so that the control unit receives the data information of the motion sensor module and adjusts the overall posture of the sole body through the adjustable support mechanism to prevent the user from falling.

[0009] Further, it further includes a power component, which is fixedly arranged at the upper end of the fixed end and connected to the control unit. The upper end of the anti - slip nail is slidably inserted into the fixed end and connected to the power component.

[0010] Further, it further includes a limit ring sleeved on the outer surface of the fixed end to prevent the fixed end from sliding up and down.

[0011] Further, the lower end of the anti - slip nail is a sharp end, and the sharp end is entirely located outside the sole body.

[0012] Further, the maximum diameter of the sharp end is greater than the diameter of the fixed end to prevent the sharp end from shrinking into the sole body.

[0013] Further, it further includes a pressure sensor array formed by two or more pressure sensors distributed at intervals and buried in the sole body for collecting pressure information of the foot; the pressure sensor array is connected to the control unit.

[0014] Further, there are three pressure sensor arrays, which are respectively located in the forefoot area, the arch area and the heel area of the sole body for detecting the pressure distribution in the corresponding areas of the sole, and then judging the center - of - gravity distribution and body posture of the user.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] By providing an adjustable support mechanism, the anti-slip nails of the adjustable support mechanism are in contact with the ground, thereby increasing the friction between the sole body and the ground and achieving an anti-slip effect.

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Refer to Figure 1, the present invention provides an intelligent anti - fall sole, which solves the problem that existing intelligent shoes lack an adaptive adjustment mechanism for different environmental conditions and have insufficient adaptability to complex and changeable actual scenarios. By setting an adjustable support mechanism, the anti - slip nails of the adjustable support mechanism are in contact with the ground, thereby increasing the friction between the sole body and the ground and achieving an anti - slip effect. And when the user is at risk of falling, the extension length of the anti - slip nails is adjusted according to the user's body posture, and the posture of the sole body is adjusted, thereby helping the human body to regain balance.

[0030] The following will describe an intelligent anti - fall sole of the present invention with reference to the accompanying drawings.

[0031] Refer to Figure 1 , which shows a top - view sectional view of the intelligent anti - fall sole of the present invention. Refer to Figure 2 , which shows a side - view sectional view of the intelligent anti - fall sole of the present invention. Refer to Figures 7 to 8 , which shows an anti - fall schematic diagram of the intelligent anti - fall sole of the present invention. The following will describe an intelligent anti - fall sole of the present invention in combination with Figure 1 、 Figure 2 、 Figure 7 and Figure 8 .

[0032] As shown in Figure 1 、 Figure 2 、 Figure 7 and Figure 8As shown in the figure, an intelligent anti - fall shoe sole of the present invention is installed at the bottom of the shoe. The anti - fall shoe sole includes: a shoe sole body 10; a motion sensor module 13 buried in the shoe sole body 10 for sensing the overall posture of the shoe sole body 10; two adjustable support mechanisms 15 respectively arranged at the mid - rear and mid - front parts of the shoe sole body 10. The adjustable support mechanism 15 includes two or more fixed ends 151 buried in the shoe sole body 10 and anti - slip nails 153 arranged at the lower ends of the fixed ends 151. The fixed ends 151 are distributed in two columns and have a gap between them. The lower ends of the anti - slip nails 153 extend out from the bottom surface of the shoe sole body 10 and contact the ground, and the extending length of the anti - slip nails 153 is adjustable to adjust the posture of the shoe sole body 10; and a control unit 11, connected to the motion sensor module 13 and the adjustable support mechanism 15. Then the control unit 11 receives the data information of the motion sensor module 13 and adjusts the overall posture of the shoe sole body 10 through the adjustable support mechanism 15 to prevent the user from falling. When walking on an uneven ground, the control unit 11 controls the extending length of the anti - slip nails 153, so that the lower ends of the anti - slip nails 153 are abutted against the ground, enabling the bottom surface of the shoe sole body 10 to fit the ground to prevent stepping into the air. When the control unit 11 determines that the user has a risk of falling, according to the specific risk situation and the data of the human body posture, it controls the extending length of the anti - slip nails 153, and then adjusts the posture of the shoe sole body 10 to help the user quickly restore body balance and achieve the anti - fall effect.

[0033] In an embodiment disclosed by the present invention, the fixed ends 151 of each adjustable support mechanism 15 are distributed in two columns, with seven in each column, distributed along the width direction of the shoe sole body 10, and the fixed ends 151 in each column are aligned with each other, so that the shoe sole body 10 can be sufficiently supported and anti - slipped by the anti - slip nails 153.

[0034] Specifically, the anti - slip nails 153 are made of tungsten carbide alloy, making the anti - slip nails 153 harder, with better wear - resistant performance, and increasing the service life of the anti - slip nails 153.

[0035] Specifically, the motion sensor module 13 includes a tri - axial accelerometer and a tri - axial gyroscope. The accelerometer can measure the acceleration changes of the shoe sole body in the X, Y, and Z three axial directions in real time, so as to obtain the speed changes and direction change information when the human body walks or moves; the tri - axial gyroscope can monitor the angular velocity and tilt angle of the shoe sole body 10 on three rotation axes in real time, and accurately sense the changes in the human body posture, such as whether the human body is tilted or shaken.

[0036] The control unit 11 adopts a high-performance microprocessor and processes the data information of the motion sensor module 13 through intelligent algorithms (including a gait analysis algorithm based on human motion mechanics and a fall risk assessment algorithm), analyzes the gait pattern of the human body, such as step length, step frequency, etc., and analyzes the overall posture of the human body through gait information, the acceleration and angular velocity of the foot, establishes a fall risk assessment model, and determines in real time whether the human body is in a fall risk state.

[0037] In a specific embodiment, it further includes a power component 150, fixedly arranged at the upper end of the fixed end 151 and connected to the control unit 11. The upper end of the anti-slip nail 153 is slidably inserted into the fixed end 151 and connected to the power component 150. By setting the power component 150, the control unit 11 adjusts the protruding length of the anti-slip nail 153 through the power component 11.

[0038] In a preferred embodiment, the power component 150 is a pneumatic pump.

[0039] In another preferred embodiment, the power component 150 is a hydraulic pump.

[0040] In a specific embodiment, it further includes a limit ring 152 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 integrally buried in the sole body 10. Since the fixed end 151 is a cylinder with the same diameter, there is a risk of falling off from the sole body 10. By setting the limit ring 152, the limit ring 152 is buried in the sole body 10. Since the diameter of the limit ring 152 is larger than the diameter of the fixed end 151, the fixed end 151 will be limited in the sole body 10 and will not slide up or down under the action of external force, preventing the fixed end 151 from damaging the structure of the sole body 10.

[0041] In a specific embodiment, the lower end of the anti-slip nail 154 is a sharp end, and the sharp end is entirely located outside the sole body 10. By setting the sharp end, sufficient friction is provided between the anti-slip nail 154 and the ground.

[0042] In a specific embodiment, the maximum diameter of the sharp end is larger than the diameter of the fixed end 151 to prevent the sharp end from shrinking into the sole body 10.

[0043] In a specific embodiment, it further includes a pressure sensor array formed by two or more pressure sensors 12 distributed at intervals and buried in the sole body 1 for collecting the pressure information of the foot; the pressure sensor array is connected to the control unit 11.

[0044] In a specific embodiment, there are three pressure sensor arrays, which are respectively located in the forefoot area, the arch area and the heel area of the sole body 1, used to detect the pressure distribution in the corresponding areas of the sole, and then judge the center of gravity distribution and body posture of the user. The three pressure sensor arrays respectively detect the pressure on the forefoot area, the arch area and the heel area of the human foot, and analyze the data through the control unit 11 to obtain the position of the human center of gravity and gait characteristics. When the pressure sensor on the right side of the sole detects an abnormal increase in pressure, it is judged that the user has a risk of falling to the right. When the sole sensor on the left side of the sole detects an abnormal increase in pressure, it is judged that the user has a risk of falling to the left.

[0045] Preferably, in an embodiment of the present invention, the pressure sensor 12 in the forefoot area has five columns, the pressure sensor 12 in the arch area has six columns, and the pressure sensor 12 in the heel area has five columns. The distance between two adjacent columns of pressure sensors 12 is the same. The pressure sensor 12 can adopt a high-precision thin-film pressure sensor and is connected to each other through a flexible circuit board, so that the pressure sensor 12 occupies a smaller space in the sole body 10, avoiding affecting the comfort of the sole body 10, and at the same time taking into account the performance of the pressure sensor 12.

[0046] Specifically, the distance between two adjacent pressure sensors 12 is the same, so that the distribution of the pressure sensors 12 is 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 a specific embodiment, it further includes an alarm communication module 14 buried in the sole body 10, which is connected to the mobile phone or smart watch of the caregiver, and sends an alarm message to the mobile phone or smart watch when the user falls. The caregiver obtains the information of the user through the mobile phone, sends an alarm message to the caregiver's mobile phone after the user falls, and the caregiver can quickly take corresponding measures. The user can view the information of the body state according to his own mobile phone or smart watch usually, and will automatically call the caregiver and the hospital when falling, and can get help in the shortest time.

[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 is connected to the user's mobile phone or smart watch, and the wireless communication module is connected to the guardian's mobile phone. The user can view their gait information or other data through their own mobile phone or smart watch, and the guardian can also view it using their own mobile phone. It also includes a GPS positioning module. When a person falls, an alarm message and location information are sent to the guardian's mobile phone through the wireless communication module, facilitating the guardian to locate the fallen person. It also includes a sound alarm device and a flashing light device. When it is detected that the user has a risk of falling or has already fallen, the sound alarm module emits an alarm sound, and the light flashing device emits a flashing light to remind the surrounding people to take countermeasures.

[0050] In a 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 a greater frictional force with the ground, and the user walks more steadily on a wet road surface, reducing the risk of falling.

[0051] Preferably, the material of the sole body 10 can be selected as polyurethane or ethylene-vinyl acetate copolymer. These two materials have the properties of being light, having good elasticity and wear resistance. It not only ensures the durability of the sole body 10, but also takes into account wearing comfort and lightness.

[0052] In a specific embodiment, the upper surface of the sole body 10 is a curved surface, and the designed curvature is adapted to the curvature of the human foot sole. Thus, the upper surface of the sole body 10 fits more closely to the human foot sole, enabling the foot sole to be fully supported by the sole body 10, making the foot sole more relaxed, and thus improving the comfort of the user.

[0053] In a specific embodiment, it also includes a battery. The battery is connected to other components, including the control unit 11, the pressure sensor 12, the motion sensor module 13, the alarm communication module 14, and the power component 150.

[0054] Preferably, the pressure sensor 12 and the motion sensor module 13 adopt a low-frequency sampling mode of 10Hz during normal use. When abnormal acceleration or abnormal pressure fluctuation on the foot sole is detected, it automatically switches to a high-frequency mode of 100Hz to cope with emergencies. By enabling the pressure sensor 12 and the motion sensor module 13 to use lower power consumption during normal use, the battery power consumption is reduced, and the overall battery life is improved.

[0055] Preferably, there are three charging schemes for the battery, including: First, wireless charging. A receiving coil is provided at the heel part of the sole body 10 and connected to the battery, and wireless charging is carried out through a wireless charger. Second, wired charging. A charging port is provided at the heel part of the sole body 10 and connected to the battery, and charging is carried out through a suitable charger. Third, energy recovery. Energy collection devices are provided in the forefoot area and the heel area of the sole body 10. When the user walks, the sole body 10 will be compressed, so that the internal energy collection devices absorb the deformation of the sole body 10 to generate electric energy, achieving the effect of charging the battery.

[0056] Next, the working principle of an intelligent anti-fall sole of the present invention will be described in detail.

[0057] When a person wears the shoes made of the anti-fall sole, the user can connect to the alarm communication module 14 via Bluetooth using a mobile phone or a smart watch, so as to obtain data such as gait information. The guardian uses their own mobile phone to connect to the alarm communication module 14 via a communication network, and then observes the user's location information, gait information, etc. After the user falls, information is sent to the guardian through the alarm communication module 14.

[0058] When the user walks on an uneven road surface, the pressure sensor array 12 transmits the bottom pressure information to the control unit 11. The control unit 11 adjusts the protruding length of the anti-slip nails 153 according to the pressure information and through the power component 150, so that the sharp ends of the anti-slip nails 153 abut against the ground, enabling the sole body 10 to have sufficient support and sufficient grip, thereby achieving the functions of anti-fall and anti-slip.

[0059] In addition, when the control unit 11 determines that the user is at risk of falling, according to the specific risk situation and the data of the human body posture, it controls the protruding length of the anti-slip nails 153, and then adjusts the posture of the sole body 10 to help the user quickly recover body balance and achieve the effect of anti-fall.

[0060] The present invention has been described in detail above in conjunction with the embodiments in the drawings. Those of ordinary skill in the art can make various variations to the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation to the present invention, and the protection scope of the present invention will be defined by the scope of the appended claims.
