[0041] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0042] This embodiment provides a lumbar support belt. Figure 1 This is a schematic diagram of the lumbar support belt according to an embodiment of the present invention, including a belt body 1, a lumbar support device 2, and a dynamic adjustment module, as detailed below.
[0043] The belt body 1 has connecting parts 11 on both sides.
[0044] The lumbar support device 2 is located in the middle interlayer of the waist belt body 1; the lumbar support device 2 includes a conductive layer.
[0045] The dynamic control module (not shown in the figure) is set on the waist belt body 1 and electrically connected to the conductive layer. The dynamic control module is used to adjust the driving voltage applied to the conductive layer according to the lumbar spine force information of the target object, so as to change the hardness of the conductive layer.
[0046] In this embodiment, the waist belt body 1 can adopt the existing waist belt design. The difference is that the waist belt body 1 in this embodiment is also provided with a lumbar support device 2. The lumbar support device 2 can dynamically provide support force according to the stress of the target object's lumbar spine to reduce the pressure on the target object's waist.
[0047] In this embodiment, a micro battery is also provided on the belt body to power the dynamic control module. Furthermore, the dynamic control module in this embodiment is also communicatively connected to a terminal, allowing signals to be transmitted from the terminal to the dynamic control module to modify parameters such as weight and pressure safety thresholds.
[0048] In this embodiment, the provided lumbar support device and dynamic adjustment module can dynamically adjust the support strength of the lumbar support according to the stress on the lumbar spine of the target object under different postures and activity states. This dynamic adjustment can effectively relieve excessive pressure on the lumbar spine, reduce damage to the lumbar spine caused by prolonged sitting or poor posture, thereby improving lumbar spine comfort and health protection.
[0049] In some alternative embodiments, the conductive layer includes a layered conductive graphene composite material, which may be processed from the layered conductive graphene composite material, carbon black, carbon fiber, etc.
[0050] The layered conductive graphene composite material in this embodiment adopts a double-layer structure, including a top linear conductive graphene layer and a bottom nonlinear conductive layer. The linear conductive graphene layer is located on the top layer, near the lumbar spine, while the nonlinear conductive layer is located below it. When energized, the conductivity of the nonlinear conductive layer increases, and the current path shifts towards the top layer, thereby generating an electro-contraction force. This force can be used for lumbar support stiffness adjustment and electro-responsive devices.
[0051] The graphene layer, composed of highly ordered carbon atoms, possesses extremely high electrical conductivity and mechanical strength, exhibiting near-linear conductivity under a conventional electric field. The nonlinear conductive layer, however, can be composed of specific composite materials, such as doped polymers, zinc oxide, or titanium dioxide, which can exhibit significant nonlinear current-voltage characteristics under certain voltage conditions. For example, when the target object is in a leaning or upright sitting posture, the lumbar spine experiences less stress. In this case, a smaller driving voltage can alter the conductivity of the layered conductive graphene composite material, thereby changing the material stiffness of the conductive layer to provide support. However, when the target object is leaning forward, a larger driving voltage is used to provide greater material stiffness, increasing support and reducing pressure on the lumbar spine.
[0052] In this embodiment, the conductive layer remains relaxed and soft when there is no voltage (power off state). Under external pressure, the material is easily deformable, making it suitable for light-load scenarios such as daily sitting postures, providing flexible cushioning. When voltage is applied to the conductive layer (power on state), the material shrinks and hardens as a whole to compensate for the pressure on the lumbar spine.
[0053] The conductive layer design in this embodiment utilizes electro-contraction force combined with external pressure. This makes it suitable for heavy-load scenarios such as bending over to move objects, providing rigid support for the lumbar spine.
[0054] The conductive layer material, which is dominated by layered conductive graphene composite material, is superior to traditional airbags. Traditional airbags are not easy to adjust the air volume on their own, and the response time takes 10 seconds or even longer. They also require an air pump in their structure and are at risk of air leakage.
[0055] This embodiment employs a layered conductive graphene composite material as the primary conductive layer material. This not only results in low production costs but also allows for precise hardness switching through fine-tuning of the voltage, replacing traditional airbags and solving problems such as slow response and easy leakage. This closed-loop design of "real-time monitoring - mechanical calculation - dynamic adjustment" overcomes the limitations of existing static support technologies. By precisely controlling the material's hardness switching characteristics with voltage, the lumbar support product can achieve efficient adaptation to dynamic pressure adjustment within a controllable cost range.
[0056] In some alternative embodiments, the lumbar support device 2 further includes:
[0057] An array pressure sensor and a dynamic control module are laid flat on the surface of the conductive layer near the target object. The array pressure sensor is communicatively connected to the dynamic control module. The array pressure sensor is used to collect the lumbar spine force information of the target object and send the lumbar spine force information to the dynamic control module and the terminal.
[0058] In this embodiment, the array pressure sensor can monitor the stress on different parts of the lumbar spine and send the stress information to the dynamic control module. The dynamic control module then determines the driving voltage applied to the conductive layer, thereby changing the hardness of the conductive layer. Simultaneously, the stress information collected by the array pressure sensor is also sent to a terminal. In this embodiment, the terminal can be a mobile terminal. A software application on the terminal can be used to monitor the stress on different parts of the lumbar spine in real time.
[0059] Furthermore, the terminal can also record the location and duration of lower back pain via touchscreen, which helps doctors in diagnosis and treatment. In addition, the terminal supports recording location, intensity (VAS / NRS score), nature (stabbing / aching), and triggering factors; the data can also be imported into an app to generate heat maps.
[0060] In this embodiment, an array of pressure sensors can comprehensively monitor the stress on the lumbar spine and display it synchronously in the app, recording the location of pain in real time. This not only helps users intuitively understand the pressure distribution on the lumbar spine but also provides doctors with systematic and comprehensive stress and symptom data support, which helps in the early detection of abnormalities, assessment of rehabilitation effects, and development of personalized treatment plans, thereby improving the accuracy and scientific nature of auxiliary medical diagnosis.
[0061] In some alternative implementations, the lumbar support belt further includes:
[0062] An inclination sensor is installed on the waist belt body 1. The inclination sensor is connected to the dynamic control module and is used to collect the inclination information between the lumbar spine and the gravity line, and send the inclination information to the dynamic control module.
[0063] The tilt sensor can be positioned relative to the lumbar spine on the lumbar belt body 1. This position allows for more accurate identification of posture, spinal lordosis angle, etc. The collected details are then sent to the dynamic control module, which automatically adjusts the pressure applied to the lumbar region to compensate for the injury, while also providing early warning alerts.
[0064] The tilt sensor in this embodiment can detect the tilt angle between the lumbar spine axis and the gravity line based on the principles of gravitational acceleration or gyroscope. In this embodiment, the tilt sensor can directly output the tilt angle value without the need for a rotating axis, making it suitable for detecting the tilt state of the lumbar spine.
[0065] In this embodiment, an inclination sensor is integrated into the waist belt body 1 and communicates with the dynamic control module in real time. This allows for precise acquisition of the inclination information of the lumbar spine relative to the gravity line, thereby enabling dynamic adjustment of the support force. This helps prevent excessive pressure on the lumbar spine caused by poor posture and improves the comfort and intelligence of the lumbar support belt.
[0066] In some alternative embodiments, the belt body 1 includes:
[0067] A memory foam layer is placed on the side of the lumbar support device 2 closest to the target object.
[0068] This embodiment also includes a memory foam layer. Memory foam has significant viscoelastic properties, which can disperse pressure and recover from impact, effectively improving the comfort of the body. It also becomes softer at higher temperatures. The memory foam layer is porous, which also facilitates heat dissipation, effectively improving the wearing comfort of the lumbar support belt.
[0069] In some alternative implementations, the lumbar support belt further includes:
[0070] A temperature regulating layer is set inside the waist belt body 1; the temperature regulating layer is made of phase change microcapsule fiber material.
[0071] In this embodiment, the temperature regulating layer can be distributed throughout the waist belt body 1. The phase change microcapsule fiber material is a smart temperature regulating fabric that encapsulates phase change material (PCM) in microcapsules and implants it into fibers. It can absorb heat at high temperatures and release heat at low temperatures, providing intelligent thermal management and thus improving comfort.
[0072] In this embodiment, phase change microcapsule fiber material is used as a smart temperature-regulating fabric. The phase change material is used to regulate the temperature through microcapsule encapsulation technology, which can effectively achieve the effects of temperature sensing, heat absorption and release. It can automatically adjust the temperature according to the changes in the external ambient temperature, thereby improving the wearer's comfort.
[0073] In some alternative implementations, the lumbar support belt further includes:
[0074] The electrode unit is located on the outer surface of the lumbar belt body 1 that contacts the lumbar spine. The electrode unit is used to monitor the lumbar spine-related neurophysiological functions and their dynamic changes.
[0075] This embodiment also includes an electrode unit, which can be an electrode pad disposed on the outer surface of the lumbar belt body 1. The electrode unit can capture and simultaneously record abnormal electromyographic signals, such as changes in muscle tone caused by nerve root compression. The signals collected by the electrode unit are then sent to a terminal, which, in conjunction with an AI diagnostic system, can preliminarily determine the health status of the lumbar spine.
[0076] This embodiment also provides a multifunctional lumbar support belt comprising a belt body 1, a lumbar support device 2, an array of pressure sensors, a memory foam layer, a temperature regulating layer, and an electrode unit. The layered structure of this lumbar support belt can be referenced. Figure 2 As shown. Figure 2 This diagram illustrates the layered design of a lumbar support belt in the middle section. Other materials can be current lumbar support materials, such as cotton, nylon, or a steel plate structure.
[0077] In some alternative embodiments, the connecting portion 11 includes:
[0078] First adjustment band 111;
[0079] The second adjustment belt 112 is spaced apart from the first adjustment belt 111;
[0080] Both the first adjustment belt 111 and the second adjustment belt 112 are equipped with adjustable buckles to prevent the waist support from shifting.
[0081] In this embodiment, the connecting part 11 is set as an adjustable buckle, which can adjust the circumference of the lumbar support belt according to the waist circumference of the target object, while preventing the position of the lumbar support belt from changing with body movement, ensuring that the lumbar support belt fits firmly against the waist, thereby effectively improving the comfort and stability of the lumbar support belt.
[0082] The lumbar support belt in this embodiment has the characteristics of high elasticity, breathability, softness and fit, wear resistance, non-deformation, and high strength.
[0083] In some optional implementations, the dynamic control module includes:
[0084] The acquisition unit is used to obtain tilt angle information;
[0085] The calculation unit is used to calculate the force information of the lumbar spine based on the tilt angle information.
[0086] Specifically, the total force on the lumbar spine can be calculated based on the tilt angle information; the force information of the lumbar spine can also be determined in various ways, such as based on the pressure on each segment of the lumbar spine of the target object.
[0087] To determine the stress information on the lumbar spine, taking the calculation of the total stress on the lumbar spine as an example, the pressure on the lumbar spine includes the component of gravity along the axial direction of the lumbar spine, i.e., the compressive force on the lumbar spine, and the component of gravity along the transverse direction of the lumbar spine, i.e., the shear force on the lumbar spine. The following formula can be used for calculation:
[0088]
[0089] Where F is the total force on the lumbar spine, W is the weight of the target object, and θ is the angle between the axis of the human lumbar spine and the gravity line.
[0090] The stress on the lumbar spine can also be calculated by consulting literature or other methods, and pressure sensors can be used to monitor pressure changes in real time.
[0091] The control unit is used to determine the driving voltage based on the force information of the lumbar spine.
[0092] In some alternative implementations, the driving voltage can be calculated using the following formula:
[0093]
[0094] F 收缩 The contractile force of the conductive layer (essentially the electrostatic force between the two electrodes, its direction causing the electrodes to move closer together, thereby squeezing the material layer and causing it to contract), ε0 is the vacuum permittivity, ε r denoted as ρ, where A is the dielectric constant of graphene, A is the overlapping area of the electrodes (the effective contact area between the electrodes and the layered conductive graphene composite material), d is the interlayer spacing (i.e., the vertical distance between the two electrodes), and V is the driving voltage, i.e., the voltage applied to the two electrodes (V).
[0095] When the driving voltage increases, the conductivity, contractile force, and stiffness of the conductive layer increase, thereby providing support for the lumbar spine. Similarly, when the driving voltage decreases, the conductivity, contractile force, and stiffness of the conductive layer decrease, thereby reducing the support provided to the lumbar spine.
[0096] In this embodiment, by using a conductive layer material mainly composed of layered conductive graphene composite material, carbon black, and carbon fiber, the hardness of the conductive layer can be dynamically adjusted according to changes in voltage, thereby providing different support forces according to different postures of the target object, and effectively relieving the pressure on the lumbar spine of the target object.
[0097] In addition, the terminal can automatically control the pressure level to provide maximum support to the lumbar spine in different postures, reducing lumbar spine damage. Furthermore, it can issue an early warning function when the stress on the lumbar spine exceeds the safe threshold in different postures, reminding the user to change posture.
[0098] In addition, in this embodiment, an alarm can be triggered if the calculated total lumbar spine pressure F exceeds the safety threshold. Specifically, this can be achieved by installing an alarm indicator on the lumbar support belt and / or by using a terminal device. See details below. Figure 3 As shown, these are the safe thresholds for the force exerted on the lumbar spine under different postures.
[0099] In this embodiment, the provided dynamic adjustment module can dynamically adjust the support strength of the lumbar support according to the stress on the lumbar spine of the target object under different postures and activity states. This dynamic adjustment can effectively relieve excessive pressure on the lumbar spine, reduce damage to the lumbar spine caused by prolonged sitting or poor posture, thereby improving the comfort of the lumbar spine and the health protection effect on the lumbar spine.
[0100] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
