Description

Technical Field

[0001] The invention belongs to the technical field of sports protection, and in particular relates to a wearable multifunctional wrist joint dynamic protection brace. Background Art

[0002] When the human body loses balance, people usually instinctively use their hands to support the ground to prevent falling and quickly restore the body's stability. This natural reaction often leads to injuries to the upper limbs, especially the wrists. For the elderly, due to the gradual degeneration of sensory organs and osteoporosis, they are at a particularly high risk of suffering wrist fractures after a fall. According to follow-up research data, the probability of the elderly falling again within three years after a fall is about 24%, and among these falls, the proportion of wrist fractures is as high as 24.13%.

[0003] In addition, cold weather, rain and snow can significantly increase the risk of wrist fractures. Cold weather conditions and slippery surfaces make it easier for the elderly to lose balance when walking, increasing the likelihood of falls and wrist fractures.

[0004] Although research on wrist fracture protection has been carried out for decades, there is still a lack of protective equipment suitable for use in daily life on the market. Although existing braces can protect the wrist and prevent injuries to a certain extent, they greatly limit the range of motion of the wrist joint, which may cause inconvenience in daily life. Therefore, the development of a new type of protective equipment that can provide adequate protection while maintaining wrist flexibility is of great significance to improving the quality of life and safety of the elderly. Summary of the invention

[0005] The present invention aims to provide a wearable multifunctional wrist joint dynamic protection brace, which can not only effectively prevent the wrist from being injured when falling, but also ensure the flexibility and freedom of the wrist joint in daily activities.

[0006] To achieve the above-mentioned purpose, the present invention provides a wearable multifunctional dynamic wrist protection brace, the key of which is: including but not limited to a palm fixing mechanism and a forearm fixing mechanism made of rigid materials, a dynamic blocking mechanism is arranged between the palm fixing mechanism and the forearm fixing mechanism around the human wrist joint, and the dynamic blocking mechanism is composed of a split inner and outer nested structure made of rigid materials; when the wrist joint moves within a normal range, the inner nesting and the outer nesting remain in a non-contact state, and once the movement of the wrist joint exceeds the normal range, the inner nesting will conflict with the outer nesting to transfer stress between the palm fixing mechanism and the forearm fixing mechanism.

[0007] Furthermore, an airbag buffer mechanism is provided at the palm of the palm fixing mechanism, and the airbag buffer mechanism is triggered instantly by the fall determination mechanism to buffer the impact force of the palm supporting the ground; a battery for supplying electricity is also provided on the palm fixing mechanism.

[0008] Furthermore, the palm cushioning mechanism includes but is not limited to a gas generator integrated in the palm and an airbag folded on the gas generator. After receiving an ignition signal issued by the fall determination mechanism, the ignition module in the gas generator can ignite the chemical substances stored in the gas generator, thereby generating a large amount of gas, so that the airbag can expand instantly.

[0009] Furthermore, the fall determination mechanism includes but is not limited to a controller arranged on the palm fixing mechanism and a detection unit worn on the human hip, the detection unit communicates wirelessly with the controller and includes an acceleration sensor and an inclination sensor; when the human body inclination angle detected by the inclination sensor is less than a set threshold and the motion acceleration detected by the acceleration sensor exceeds a set threshold, the controller will determine that the fall is unavoidable and send an ignition signal to the ignition module.

[0010] Furthermore, a power generation mechanism is also arranged on the forearm fixing mechanism, and the power generation mechanism charges the battery through an electromagnetic coupling mechanism.

[0011] Furthermore, the power generation mechanism includes but is not limited to a graphene heat collection layer arranged on the inner surface of the forearm fixing mechanism and a temperature difference power generation element arranged on the inner side of the graphene heat collection layer.

[0012] Furthermore, the power generation mechanism also includes a photovoltaic power generation panel arranged on the outer surface of the forearm fixing mechanism.

[0013] Furthermore, the electromagnetic coupling mechanism includes but is not limited to an energy transmitting coil arranged on the outer nesting layer, and an energy receiving coil arranged on the inner nesting layer, the energy transmitting coil is connected to the power generation mechanism through an energy transmitting circuit, and the energy receiving coil is connected to the battery through an energy receiving circuit.

[0014] Furthermore, the energy transmitting coil and the energy receiving coil are both tubular spiral coils.

[0015] Furthermore, it also includes a flexible sleeve that can be worn on the palm and forearm, and the flexible sleeve includes at least a section of heat-conducting material located in the forearm fixing mechanism.

[0016] Compared with the prior art, the present invention has the following remarkable effects:

[0017] (1) The wearable multifunctional wrist joint dynamic protection brace presented by the present invention not only has excellent protective performance, but also significantly guarantees the flexibility of the wrist joint, ensuring that the wearer is almost free from any restrictions in daily life. Its unique dynamic blocking mechanism design allows the wrist joint to move freely within the normal range of motion, and once the movement exceeds the normal range, it will immediately provide effective support and blocking, effectively preventing wrist injuries;

[0018] (2) By providing an airbag cushioning mechanism, the present invention provides additional safety protection for the wearer at the moment of falling. The accurate judgment of the fall judgment mechanism can make the airbag expand in a very short time, effectively absorbing the impact force when the palm is on the ground, thereby greatly reducing the risk of wrist contusion and fracture;

[0019] (3) The present invention also fully considers the sustainable use of energy. The power generation mechanism on the forearm fixing mechanism charges the battery through the electromagnetic coupling mechanism, which not only achieves energy saving and environmental protection, but also significantly extends the use time of the brace. In addition, the various power generation methods of the graphene temperature difference power generation element and the photovoltaic power generation panel provide a stable energy supply for the brace;

[0020] (4) The flexible sleeve design of the present invention not only improves the wearing comfort, but also effectively conducts the heat of the forearm through the heat conductive material, further improving the power generation efficiency. At the same time, the energy transmitting coil and energy receiving coil of the tubular spiral coil ensure the stability and efficiency of energy transmission. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0032] Figures 1 to 5 The first embodiment of the present invention is shown: a wearable multifunctional dynamic wrist protection brace, including but not limited to a palm fixing mechanism 1 and a forearm fixing mechanism 2 made of rigid materials, a dynamic blocking mechanism 3 is arranged between the palm fixing mechanism 1 and the forearm fixing mechanism 2 around the human wrist joint, and the dynamic blocking mechanism 3 is composed of a split inner and outer nested structure made of rigid materials; when the wrist joint moves within a normal range, the inner nesting 301 and the outer nesting 302 remain in a non-contact state, once the movement of the wrist joint exceeds the normal range, the inner nesting 301 will conflict with the outer nesting 302 to transfer stress between the palm fixing mechanism 1 and the forearm fixing mechanism 2.

[0033] like Figure 2 and Figure 5 As shown, in a specific implementation, an airbag 402 buffer mechanism 4 is also provided at the palm of the palm fixing mechanism 1, and the airbag 402 buffer mechanism 4 is instantly triggered by the fall determination mechanism 5 to buffer the impact force of the palm supporting the ground; a battery 6 for supplying electricity is also provided on the palm fixing mechanism 1.

[0034] The palm cushioning mechanism includes but is not limited to a gas generator 401 integrated in the palm and an airbag 402 folded on the gas generator 401. After receiving the ignition signal from the fall determination mechanism 5, the ignition module in the gas generator 401 can ignite the chemical substances stored in the gas generator 401, thereby generating a large amount of gas to make the airbag 402 expand instantly. Preferably, in order to enhance the reliability and stability of the airbag 402 cushioning mechanism 4, a set of backup triggering mechanisms can be added. Under this mechanism, a manual trigger carried by the guardian can be provided in conjunction. When the guardian senses that the brace wearer is about to fall but the fall determination mechanism 5 fails to respond in time, the guardian can actively trigger the manual trigger, thereby igniting the chemical substances in the gas generator 401 and expanding the airbag 402, providing additional safety protection.

[0035] On the other hand, the wrist joint sizes and activity habits of different users are taken into consideration. Therefore, the inner nesting 301 and the outer nesting 302 of the dynamic blocking mechanism 3 are both replaceable, and the user can adjust the gap between the inner and outer nesting according to their actual situation to ensure that the brace can provide the best support effect under different ranges of activity. Preferably, in order to prevent the inner nesting 301 and the outer nesting 302 from being damaged and deformed during instantaneous contact, a flexible buffer ring can be provided on the outer surface of the inner nesting 301 or / and the inner surface of the outer nesting 302.

[0036] like Figure 1 and Figure 5As shown, in this embodiment, the fall judgment mechanism 5 includes but is not limited to a controller 501 arranged on the palm fixing mechanism 1 and a detection unit worn on the human hip, the detection unit communicates wirelessly with the controller 501, and includes an acceleration sensor and an inclination sensor; when the human body inclination angle detected by the inclination sensor is less than a set threshold value, and the motion acceleration detected by the acceleration sensor exceeds the set threshold value, the controller 501 will determine that the fall is inevitable and send an ignition signal to the ignition module. In general, the acceleration threshold of the elderly is set within the range of 5 to 7 meters per second, and the inclination threshold is between 65 degrees and 75 degrees. The human body inclination refers to the angle between the human body and the horizontal plane, which is about 90 degrees when standing normally and close to 0 degrees when lying flat. When the controller 501 obtains that the acceleration of the elderly exceeds the above threshold value, and the human body inclination angle is less than the set threshold value, the controller 501 will determine that the elderly is about to fall, which means that the fall is inevitable. In addition, in order to further enhance the intelligence level of the wearable multifunctional wrist joint dynamic protection brace, the controller 501 can also be connected to a smart phone or other smart device to achieve real-time data transmission and remote monitoring. Guardians and users can view the working status of the brace through smart devices, receive fall warning information, and even adjust the threshold of the fall determination mechanism 5 to adapt to different activity scenarios and personal needs. This intelligent design not only enhances the practicality and convenience of the brace, but also provides users with a more personalized protection experience.

[0037] See also Figure 4 and Figure 5 In specific application, a power generation mechanism 7 is also provided on the forearm fixing mechanism 2, and the power generation mechanism 7 charges the storage battery 6 through the electromagnetic coupling mechanism 8. The power generation mechanism 7 includes but is not limited to a graphene heat collection layer provided on the inner surface of the forearm fixing mechanism 2 and a temperature difference power generation element 701 provided inside the graphene heat collection layer.

[0038] The graphene heat collecting layer can efficiently convert the heat emitted by the human body into electrical energy, while the thermoelectric power generation element 701 generates electrical energy by utilizing the temperature difference effect between the inner and outer surfaces of the forearm fixing mechanism 2. This design not only realizes the sustainable utilization of energy, but also effectively improves the energy conversion efficiency.

[0039] In this embodiment, the electromagnetic coupling mechanism 8 includes but is not limited to an energy transmitting coil 801 provided on the outer nesting 302, and an energy receiving coil 802 provided on the inner nesting 301, the energy transmitting coil 801 is connected to the power generation mechanism 7 through an energy transmitting circuit, and the energy receiving coil 802 is connected to the battery 6 through an energy receiving circuit. Preferably, both the energy transmitting coil 801 and the energy receiving coil 802 are tubular spiral coils. This design ensures that energy can be transmitted stably and efficiently even during wrist joint movement. The use of tubular spiral coils not only improves the efficiency of electromagnetic coupling, but also enhances the durability and stability of the coil, so that the entire brace can still maintain good performance during long-term use.

[0040] In addition, the wearable multifunctional wrist joint dynamic protection brace of the present invention also includes a flexible sleeve 9 that can be worn on the palm and forearm (refer to Figure 4 and Figure 5 ). The flexible sleeve 9 not only improves the wearing comfort, but also the thermal conductive material contained therein can effectively conduct the heat of the forearm, further improving the power generation efficiency. This design not only reflects the ultimate pursuit of user experience, but also demonstrates the uniqueness of the present invention in energy utilization.

[0041] Figure 6 and Figure 7 The second embodiment of the utility model is shown in the figure, which further improves the charging performance on the basis of the first embodiment. Specifically, the power generation mechanism 7 is newly provided with a photovoltaic power generation panel 702 arranged on the outer surface of the forearm fixing mechanism 2. The photovoltaic power generation panel 702 is made of high-efficiency single-crystal silicon material, has high conversion efficiency and strong weather resistance, can operate stably under a variety of lighting environments, and provides continuous power supply for the battery 6. In addition, the design of the photovoltaic power generation panel 702 takes into account the integration with the forearm fixing mechanism 2, which not only maintains the beautiful appearance, but also ensures the comfort and stability when worn.

[0042] The photovoltaic power generation panel 702 disposed on the outer surface of the forearm fixing mechanism 2 can provide additional power to the battery 6 under light conditions, further enhancing the endurance of the brace. In practical applications, this multi-energy power supply method not only provides a stable energy supply for the brace, but also effectively prolongs the use time of the brace and improves the wearing experience of the user.

[0043] In summary, the wearable multifunctional wrist joint dynamic protection brace presented by the present invention not only has excellent protective performance, but also significantly guarantees the flexibility of the wrist joint, ensuring that the wearer is almost not restricted in daily life. Its unique dynamic blocking mechanism 3 design allows the wrist joint to move freely within the normal range of motion, and once the movement exceeds the normal range, it will immediately provide effective support and blocking, effectively preventing wrist injuries; by setting the airbag 402 buffer mechanism 4, the present invention provides additional safety protection for the wearer at the moment of falling. The precise judgment of the fall judgment mechanism 5 can make the airbag 402 expand in a very short time, effectively absorbing the impact force when the palm is supporting the ground, thereby greatly reducing the risk of wrist contusion and fracture; the present invention also fully considers the sustainable use of energy. The power generation mechanism 7 on the forearm fixing mechanism 2 charges the battery 6 through the electromagnetic coupling mechanism, which not only achieves energy saving and environmental protection, but also significantly extends the use time of the brace. In addition, the various power generation methods of the graphene temperature difference power generation element 701 and the photovoltaic power generation panel 702 provide a stable energy supply for the brace; the design of the flexible sleeve 9 of the present invention not only improves the wearing comfort, but also effectively conducts the heat of the forearm through the thermal conductive material, further improving the power generation efficiency. At the same time, the energy transmitting coil 801 and the energy receiving coil 802 of the tubular spiral coil ensure the stability and efficiency of energy transmission.
