Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation equipment technology, specifically to a self-generating intelligent temperature-controlled rehabilitation protective gear system. Background Technology

[0002] With the popularization of national fitness awareness and the arrival of an aging society, the demand for sports injury prevention and rehabilitation of chronic joint strain is increasing. Traditional protective gear (such as knee braces and lumbar supports) mainly provides physical support and compression, with limited functionality. In recent years, while some existing smart temperature-controlled protective gear can achieve precise cold or hot compresses, they rely entirely on built-in or external batteries for power, leading to battery anxiety, and are particularly unsuitable for prolonged outdoor activities, emergency rescue, or scenarios without a stable power source. Other wearable devices that utilize human kinetic energy to generate electricity are either structurally complex and bulky, affecting movement, or have limited power generation and rudimentary energy management, making it difficult to stably drive the high-power-demand semiconductor temperature control modules. Furthermore, power generation and physiotherapy functions are often isolated, failing to form an efficient and synergistic system.

[0003] Therefore, there is an urgent need for a rehabilitation brace system that can efficiently recover and utilize human movement energy, intelligently manage and distribute it to drive precise temperature-controlled physiotherapy, and also has the advantages of wearing comfort, functional integration and ease of use. Summary of the Invention

[0004] The purpose of this invention is to provide a self-generating intelligent temperature-controlled rehabilitation protective gear system to solve the problems of poor battery life, limited functionality, low system integration, and difficulty in balancing wearing comfort and functionality in existing intelligent physiotherapy protective gear.

[0005] To achieve the above objectives, the present invention provides a self-generating intelligent temperature-controlled rehabilitation protective gear system, comprising: The main body of the lumbar support contains a power generation module, an energy management module, and a main control module. At least one functional protective gear is used to be worn on a target joint of the human body, and its interior is equipped with a multimodal temperature control module, a temperature sensing unit, and a control subunit that is communicatively connected to the main control module. The power generation module is used to convert the mechanical energy of human activity into electrical energy. The energy management module is electrically connected to the power generation module and is used to store electrical energy and supply power to the main control module and the functional protective gear; The main control module is communicatively connected to the energy management module and the control subunit of the functional protective gear, and is used to control the distribution of energy and send temperature control commands to the functional protective gear; The multimodal temperature control module is used to cool or heat the target joint according to the temperature control command. The lumbar support body and the functional protective gear are connected by a detachable connection mechanism for power and data connection.

[0006] In the above solution, the energy capture and management center (the lumbar support body) is separated from the functional execution terminal (functional brace) and connected in a detachable manner. This design solves the pain points of traditional single braces having limited functionality and relying on external power sources, realizing a self-powered and scalable intelligent rehabilitation system. The lumbar support acts as the "power station" and "brain," while the functional brace acts as the "air conditioner," allowing users to power and control multiple joints requiring temperature-controlled physiotherapy (such as both knees, elbows, and even through an adapted lumbar support pad) simply by wearing a single power generation center. This significantly improves the system's portability, battery life, and functional flexibility, providing an integrated solution for outdoor sports, home rehabilitation, and other scenarios.

[0007] In a preferred embodiment of this application, the power generation module includes: A pull-wire mechanism, the pull-wire end of which is adapted to connect to the user's lower limb or the functional protective gear; A coil spring mechanism, coupled to the pull wire mechanism, is used to store and release the elastic potential energy generated when the pull wire mechanism is pulled. A one-way transmission mechanism is connected to the output end of the coil spring mechanism; The micro generator has its input shaft connected to the coiled spring mechanism via the unidirectional transmission mechanism, so that the coiled spring mechanism can drive the micro generator to rotate unidirectionally to generate electricity when releasing elastic potential energy.

[0008] In the above scheme, the cascading design of "wire-spring-one-way transmission-generator" converts the periodic relative displacement between the waist and lower limbs during walking into the elastic potential energy of the spring, which is then temporarily stored. This energy is then smoothly released by the spring and used to drive the generator for efficient one-way power generation via a one-way bearing. This design effectively filters out the disordered vibrations of human movement, converting intermittent, reciprocating mechanical energy into stable, unidirectional electrical energy output, improving power generation efficiency and power quality. Simultaneously, it places the main mechanical structural weight on the waist, avoiding additional burden on the joints.

[0009] As a preferred embodiment of this application, the energy management module includes a rechargeable battery, a charge / discharge management circuit, and a dynamic power distribution unit; The dynamic power distribution unit is configured to dynamically adjust the power allocated to each power-consuming unit based on the remaining charge of the rechargeable battery, the real-time output power of the power generation module, and the working mode and power requirements of each of the functional protective gears.

[0010] In the above solution, by integrating a dynamic power distribution unit, the system can monitor three key variables in real time: "power generation input," "battery capacity," and "the needs of various protective gears," and dynamically adjust the power output strategy. For example, when the battery is low, priority is given to ensuring basic physiotherapy for one knee brace; when power generation is abundant, it simultaneously supports high-power modes for multiple protective gears, or it can utilize battery power when the user is stationary and switch to a power generation-while-using mode when the user is active. This significantly improves overall energy efficiency, extends effective usage time, and enhances the system's adaptability and reliability under different usage intensities.

[0011] In a preferred embodiment of this application, the multimodal temperature control module includes a semiconductor refrigeration chip, a flexible heat-conducting layer that is attached to the cold / hot end of the semiconductor refrigeration chip, and a heat dissipation component for dissipating heat from the hot end of the semiconductor refrigeration chip.

[0012] In the above solution, the thermoelectric cooler acts as an actuator, enabling rapid switching between cooling and heating via current control, meeting the different rehabilitation needs of "cold compress" (acute injury) and "hot compress" (chronic strain). A flexible, temperature-regulating thermal layer ensures that cold / heat is evenly and gently conducted to the skin, avoiding localized overcooling or overheating caused by traditional ice packs or heating pads, thus improving comfort and safety. The heat dissipation component ensures efficient heat dissipation at the working end of the thermoelectric cooler, maintaining its cooling / heating efficiency and service life.

[0013] In a preferred embodiment of this application, the main control module includes a microprocessor, a wireless communication module, and a memory storing rehabilitation treatment algorithms; The rehabilitation treatment algorithm includes: selecting one of a variety of preset temperature control modes based on the received user instructions or the user status automatically determined by the sensor. The variety of temperature control modes includes at least a continuous cold compress mode, a continuous hot compress mode, and a hot and cold alternating cycle mode.

[0014] In the above solution, by pre-setting multiple rehabilitation treatment algorithms, the system can respond to manual selection by the user, or more advancedly, automatically determine the user's state (such as having just finished high-intensity exercise) through sensor data (such as temperature and motion sensors), thereby automatically activating the most suitable temperature control mode (such as "deep cold compress mode after exercise"). This lowers the user's operating threshold, ensures the scientific nature and timeliness of physiotherapy, and upgrades traditional passive protective gear into an active intelligent rehabilitation assistant.

[0015] In a preferred embodiment of this application, the functional protective gear is a knee brace, and its fabric substrate is provided with the multimodal temperature control module and the temperature sensing unit corresponding to the upper and lower edges of the patella and the medial and lateral joint lines of the human knee joint.

[0016] In the aforementioned solution, the temperature control module and sensor array are precisely aligned with high-incidence areas of knee injuries, such as the upper and lower edges of the patella and the medial and lateral joint lines. This enables targeted cold and heat therapy for common conditions like patellar tendinitis, perimeningitis, and collateral ligament sprains. This anatomically adapted design ensures that limited cold / heat energy can directly and efficiently act on the affected area, improving therapeutic efficacy and avoiding energy waste. This exemplifies how the technical solution aligns with clinical needs.

[0017] In a preferred embodiment of this application, the connection mechanism between the lumbar support body and the functional protective gear is an integrated flexible cable. The integrated flexible cable integrates a power transmission line and a data communication line, and its two ends are provided with quick-plug interfaces to prevent mis-insertion.

[0018] In the above solution, the integrated flexible cable combines power and data transmission, simplifying wiring and improving connection reliability. The quick-plug interface, designed to prevent mis-insertion, greatly enhances the convenience of wearing and removing the cable, resolving common issues of interface confusion and cumbersome wiring when connecting multiple devices. This makes the overall system's user experience comparable to ordinary wearable protective gear, enhancing the product's practicality and user-friendliness.

[0019] In a preferred embodiment of this application, the pull end of the pull mechanism is connected to a hook assembly that can be quickly detached from the functional protective gear, or the pull end is directly or via a guide wheel connected to a separate coupling strap specifically designed for binding to the user's leg.

[0020] In the above solutions, the hook assembly connecting the functional protective gear achieves integrated wearability of the power generation mechanism and the physiotherapy terminal, suitable for most daily and sports scenarios. The solution connecting an independent coupling strap allows users to generate electricity using walking kinetic energy even when only power generation is needed (such as charging other devices) or when wearing non-smart traditional protective gear, expanding the system's application range. Both methods facilitate quick disassembly, meeting the personalized usage habits of different users.

[0021] As a preferred embodiment of this application, a mobile terminal application is also included; The mobile terminal application is configured to establish a connection with the main control module via a wireless communication module, and to display the system's power generation status, energy storage capacity, working status of each functional protective gear, and temperature information to the user, and to receive user settings instructions for temperature control mode, temperature, and duration parameters.

[0022] In the aforementioned solution, users can easily monitor the system's real-time power generation, remaining battery power, current temperature of various parts, and operating mode via an app, receiving comprehensive and visualized data feedback. Simultaneously, users can remotely and precisely adjust treatment parameters and set treatment plans. This significantly enhances users' sense of control and participation in the treatment process, facilitates long-term tracking of rehabilitation data, and makes more intelligent health management possible.

[0023] As a preferred embodiment of this application, the outer shell of the lumbar support body is provided with a system status indicator light to indicate the power generation status, battery level, connection status with functional protective gear, and working mode.

[0024] In this solution, users don't need to take out their phones; they can quickly determine whether the system is generating power normally, whether the battery is sufficiently charged, and whether the functional protective gear is connected and working properly simply by checking the color or flashing pattern of the indicator lights on the lumbar support. This localized interactive design is especially important during exercise, when the phone is inconvenient to operate, or when it's out of power. It enhances the system's basic usability and reliability, and serves as a powerful complement to wireless intelligent control methods.

[0025] In summary, the beneficial effects achieved by this application include: 1. By using a high-efficiency human kinetic energy generation module, the mechanical energy of daily walking is converted into electrical energy and stored, which fundamentally solves the battery life problem of smart physiotherapy protective gear, making it particularly suitable for outdoor and power-free environments.

[0026] 2. The dynamic power distribution unit realizes intelligent scheduling among power generation, energy storage, and power consumption, maximizing energy utilization efficiency and ensuring the stable operation of core physiotherapy functions.

[0027] 3. The semiconductor-based temperature control module can accurately realize cold compress, hot compress and alternating modes, and directly provide scientific physiotherapy for different stages of joint injury (acute phase, chronic phase and rehabilitation phase).

[0028] 4. Adopting a distributed architecture of "control center (lumbar support) + execution terminal (functional protective gear)", one lumbar support can power and control multiple joint protective gears, with high system integration and strong scalability.

[0029] 5. The heavier power generation and control unit is positioned around the waist, while the joint braces are lightweight and flexible. Quick-connect interfaces and a mobile app make the entire system extremely convenient to wear, connect, and control.

[0030] 6. The built-in rehabilitation algorithm supports automatic mode selection, and the mobile APP provides comprehensive data interaction and personalized settings, realizing the upgrade from passive wear to active intelligent rehabilitation. Attached Figure Description

Detailed Implementation

[0036] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0037] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0038] like Figures 1-4As shown, this application discloses a self-generating intelligent temperature-controlled rehabilitation brace system, which includes a lumbar support body 100, which internally houses a power generation module 110, an energy management module 120, and a main control module 130; at least one functional brace 200 for wearing on a target joint of the human body, which internally houses a multi-modal temperature control module 210, a temperature sensing unit, and a control subunit communicatively connected to the main control module; the power generation module 110 is used to convert mechanical energy during human activity into electrical energy; the energy management module 120, in conjunction with the power generation module, converts mechanical energy into electrical energy; and the power generation module 110 converts mechanical energy into electrical energy during human activity. The electrical module 110 is electrically connected and used to store electrical energy and supply power to the main control module 130 and the functional protective gear 200; the main control module 130 is communicatively connected to the energy management module 120 and the control subunit of the functional protective gear 200, and is used to control the distribution of energy and send temperature control commands to the functional protective gear; the multi-modal temperature control module 210 is used to cool or heat the target joint area according to the temperature control command; wherein, the waist support body 100 and the functional protective gear 200 are connected by a detachable connection mechanism to achieve power and data connection.

[0039] The above solution separates the energy capture and management center (the lumbar support body) from the functional execution terminal (functional brace) and connects them in a detachable manner. This design solves the pain points of traditional single braces having limited functionality and relying on external power sources, realizing a self-powered and scalable intelligent rehabilitation system. The lumbar support acts as the "power station" and "brain," while the functional brace acts as the "air conditioner," allowing users to power and control multiple joints requiring temperature-controlled physiotherapy (such as both knees, elbows, and even with an adapted lumbar support pad) simply by wearing one power generation center. This significantly improves the system's portability, battery life, and functional flexibility, providing an integrated solution for outdoor sports, home rehabilitation, and other scenarios.

[0040] The following section uses the functional knee brace 201 as an example of the functional protective gear 200 to further illustrate the self-generating intelligent temperature-controlled rehabilitation protective gear system of this application.

[0041] Reference Figure 1 As shown, the self-generating intelligent temperature-controlled rehabilitation support system in this example includes a lumbar support body 100, two integrated flexible cables, and two functional knee braces 201 (one for the left knee and one for the right knee). The lumbar support body 100 is generally strip-shaped with a hollow internal structure. Its outer shell is made of lightweight, high-strength engineering plastic, and the inner side, where it fits against the human waist, is padded with memory foam to enhance comfort. The surface of the shell is equipped with system status indicator lights, including a green LED to indicate the power generation status, a three-color LED (red / yellow / green) to indicate the battery level, and a blue LED to indicate the connection status with the functional knee braces.

[0042] Continue to refer to Figure 2As shown, the lumbar support body 100 integrates a power generation module 110, an energy management module 120, and a main control module 130. Preferably, the power generation module 110 specifically includes a cable pulling mechanism, a coiled spring mechanism, a one-way bearing, and a micro generator. The cable pulling mechanism includes a cable 111 wound on a damped reel. The cable 111 is made of ultra-high molecular weight polyethylene fiber, with a diameter of approximately 1 mm, possessing both high strength and flexibility. The end of the cable 111 has a hook made of engineering plastic. The reel is coaxially fixed to the input shaft of a coiled spring mechanism. The coiled spring mechanism is a planar spiral spring, and its effective number of turns is designed to store sufficient elastic potential energy within a stroke of approximately 8-12 cm when the cable 111 is stretched. The output shaft of the coiled spring mechanism is connected to the input shaft of the micro generator via a one-way bearing. The micro generator selected in this embodiment is a coreless three-phase AC generator with an outer diameter of 40mm, a thickness of 20mm, a rated operating voltage of 5V, and a starting torque of less than 0.04N·m to adapt to low-speed starting. Its working principle is as follows: When a user walks, the relative distance between the legs and waist increases. This pulls the cable 111 via a hook, causing the winding wheel to rotate and tightening the coiled spring to store energy. When the user changes pace and retracts the leg, the tension in the cable 111 decreases, and the coiled spring releases its stored elastic potential energy, driving the winding wheel to reverse and retract the cable 111. Simultaneously, a one-way bearing drives the input shaft of the micro-generator to rotate unidirectionally to generate electricity. Tests show that when an adult male walks normally at 5 km / h, the cable mechanism on one side can complete approximately 70-80 stretch-retract cycles per minute on average, driving the generator to produce a continuous average electrical power of approximately 0.8-1.2W.

[0043] Furthermore, referring to Figure 4As shown, the energy management module 120 includes a rechargeable battery 121, a charge / discharge management circuit 122, and a dynamic power distribution unit 123. The rechargeable battery 121 is a 2000mAh lithium polymer pouch battery with an output voltage of 3.7V. The charge / discharge management circuit 122 is responsible for rectifying and regulating the three-phase AC power generated by the micro-generator to charge the battery 121, and managing the charge / discharge process of the battery 121, providing overcharge, over-discharge, and overcurrent protection functions. The dynamic power distribution unit 123 is implemented by a dedicated power management chip, which communicates with the main control module 130 via an I2C bus. This unit monitors the remaining charge (SOC) of the battery 121 and the real-time input current / voltage of the generator module 110 in real time, and receives information from the main control module 130 regarding the operating modes and power requirements of each functional knee brace 201. Based on this data, its built-in algorithm dynamically determines the power distribution strategy. For example, when the battery level is below 20% and only one knee brace is working in "powerful cooling" mode (power consumption of about 4W), unit 123 may limit its power to "constant temperature cooling" mode (about 2.5W) and prioritize using the generated power to charge the battery; when the battery level is above 80% and both knees are working in "heating" mode (about 3W per side), unit 123 can instruct the main control module 130 to allow both knees to operate at full power and store the excess generated power.

[0044] In a preferred embodiment of this example, the main control module 130 is based on a low-power ARM Cortex-M series microprocessor 131, which is connected to a Bluetooth 5.0 low-power wireless communication module 132 and an 8MB flash memory 133. The memory 133 contains the system control program and rehabilitation treatment algorithm. The algorithm predefines multiple temperature control modes, including but not limited to: a) sports recovery mode: continuous cold compress, target temperature set at 10±2°C, duration 20 minutes; b) slow pain relief mode: continuous hot compress, target temperature set at 45±2°C, duration 30 minutes; c) blood circulation and stasis removal mode: alternating hot and cold compresses, with a cycle of 3 minutes of cold compress (15°C) and 2 minutes of hot compress (42°C) repeated 6 times. The microprocessor 131 communicates with the functional knee brace 201 via a cable, sends temperature control commands and receives temperature feedback to achieve closed-loop control; at the same time, it pairs with the user's smartphone APP via the Bluetooth module 132 to receive user commands and upload system status data. Preferably, the functional knee brace 201 includes a fabric substrate 201 made of a composite of elastic spandex and CoolMax fabric. On the inner side of the substrate 201, corresponding to four key anatomical locations of the human knee joint—the upper edge of the patella, the lower edge of the patella, the medial joint line, and the lateral joint line—four independent multimodal temperature control units 210 are embedded using a hot-pressing process. At the core of each temperature control unit 210 is a 20mm × 20mm × 3mm semiconductor cooling chip 211. On the skin-facing side of the cooling chip 211, a 0.1mm thick flexible graphene heat dissipation film 212, measuring 40mm × 40mm, is tightly bonded to it with thermally conductive silicone grease to ensure rapid and uniform heat / cold diffusion. On the skin-removing side of the cooling chip 211, a miniature heat dissipation module is fixed with screws. This module includes a copper heat dissipation substrate, an array of aluminum heat dissipation fins, and a 30mm diameter miniature turbine fan 213. Near the center of each graphene temperature-regulating film 212, a patch-type digital temperature sensor (such as DS18B20) is embedded for real-time monitoring of the skin surface temperature in that area. All temperature control units 210 and sensors are connected to a flexible printed circuit board (FPC) control sub-board located on the side of the knee brace, which integrates drive circuitry and communication chips. A miniature connector interface with a waterproof rubber plug is located on the upper outer side of the knee brace.

[0045] The integrated flexible cable is approximately 80cm long. Its core consists of two power supply wires (positive and negative) and a pair of twisted pairs for CAN bus communication, all wrapped with a wear-resistant braided layer. One end of the cable is a male connector, which inserts into the waterproof female connector on the side of the lumbar support body 100; the other end is a female connector, which inserts into the connector of the functional knee brace 201. The male and female connectors use an asymmetrical physical structure design to prevent mis-insertion.

[0046] Usage and testing examples: When wearing the system, the user first secures the lumbar support 100 around the waist and then places the two functional knee braces 201 on each knee, ensuring that the four temperature control units 210 are roughly aligned with the key areas of the knee joint. Next, the two cables are connected to the lumbar support and the left and right knee braces respectively. Finally, the hook at the end of the pull cable 111 is attached to the hanging ring on the upper outer side of the corresponding knee brace 200. The user then starts walking after activating the system.

[0047] Power generation performance test: A 70kg adult test subject was invited to walk at a speed of 5km / h on flat ground for 30 minutes. Monitoring via the built-in circuitry showed that the total electrical energy generated by the power generation module 110 (both sides) was approximately 1.8W on average, and approximately 0.9Wh in 30 minutes. During this period, the system operated the knees in a "constant temperature cooling" mode (set at 15°C, approximately 2W power consumption per side). Within 30 minutes, the system battery level slowly decreased from an initial 50% to 47%, indicating that under moderate-intensity use, the system's power generation can cover approximately 70% of the energy consumption, significantly extending the battery life.

[0048] Temperature control performance test: In an environment with a room temperature of 25°C, the single-function knee brace 201 was worn on a bionic knee joint model, and the "movement recovery mode" (target 10°C) was activated. Temperature sensor data showed that within 150 seconds after activation, the temperature at all four monitoring points dropped from room temperature to within the range of 10±0.5°C and remained stable, with temperature fluctuations of less than ±0.3°C, verifying the precise temperature control capability.

[0049] Intelligent linkage example: After finishing a football match, a user can activate the "Sports Recovery Mode" with a single click via a mobile app. The main control module 130 detects that the user is stationary via motion sensors (which may include a built-in accelerometer, not shown in the diagram) and instructs the knee braces to activate powerful cooling. Simultaneously, the dynamic power distribution unit 123 detects that the battery level is 65%, determining that the battery is sufficient and allowing the knee braces to operate at full power (approximately 8W total power consumption) for 20 minutes. During this time, the user walks home, and the power generation module continues to work to replenish the battery. After 20 minutes, the system automatically stops the cooling and sends a notification to the app.

[0050] Preferably, the mobile terminal application provides the following main interfaces: Main control panel: Displays the lumbar support battery level, real-time power generation, current temperature of left and right knees, and setting mode in card format.

[0051] Mode selection interface: Displays all preset rehabilitation modes (exercise recovery, chronic pain relief, blood circulation improvement, etc.) in the form of an icon list, and supports user-defined modes (setting temperature, duration, and alternation rhythm of hot and cold).

[0052] Historical records: Displays the duration, mode, energy consumption, and power generation data for each use in chart format.

[0053] Device Management: Used to bind / unbind devices, update firmware, and set smart reminders (such as low battery reminders and treatment completion reminders).
