Description

Technical Field

[0001] This invention relates to a personal temperature regulation device, and more particularly to a wearable human body temperature regulation device. Background Technology

[0002] Wearable body temperature regulation devices have wide applications in various fields, such as outdoor sports, military operations, industrial production, and medical care. In outdoor sports, athletes often wear these devices to cope with high or low temperatures, maintain body temperature balance, and improve athletic performance. In industrial settings, workers use them to prevent heatstroke or frostbite and ensure workplace safety. In the medical field, they are used for patient temperature regulation or rehabilitation, such as helping to lower the temperature of feverish patients or providing local warmth for postoperative patients. The process typically involves the user wearing the device on a body part (such as the back, neck, or limbs), where it actively dissipates or heats itself through a built-in temperature regulation module (such as a miniature fan, thermoelectric cooler, or heating element). The device is battery-powered, and users can adjust the temperature settings via a simple controller or smart device to achieve personalized thermal comfort management. With advancements in wearable technology, these devices are gradually integrating more functions, such as sensor monitoring and wireless connectivity, but their core function remains the same: regulating local body temperature through physical means to enhance the user's adaptability to changing environments.

[0003] In existing technologies, wearable temperature regulation devices face significant limitations in their main material design. While using soft, elastic materials initially provides good fit and comfort, prolonged use leads to elastic fatigue, reducing the fit and affecting the uniformity and efficiency of temperature regulation. Furthermore, soft materials lack structural strength, limiting internal airflow and resulting in weak heat dissipation or heating, failing to meet the demands of high-intensity applications. Conversely, while rigid materials can increase airflow and enhance regulation, their lack of flexibility leads to poor comfort and difficulty adapting to varying body shapes, potentially causing pressure or gaps and poor fit, thus reducing user experience and practicality. This contradiction in material selection hinders the widespread adoption and performance optimization of these devices. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a wearable human body temperature regulation device that balances wearing stability, comfort, and efficient adjustment capabilities.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A wearable human body temperature regulation device includes a support body made of rigid material and having a plurality of ventilation holes thereon. Two shoulder straps for wearing the device are symmetrically arranged on the support body. When worn, the support body fits against the upper back of the human body. A plurality of temperature regulation mechanisms that fit against the upper back and chest of the human body are respectively arranged on the support body and the shoulder straps. The support body includes a first fitting area and a second fitting area. When worn, the first fitting area and the second fitting area fit against the scapular region and the upper latissimus dorsi muscle region, respectively. A plurality of temperature regulation mechanisms arranged on the support body are respectively arranged in the first fitting area and the second fitting area. The temperature regulation mechanisms arranged on the shoulder straps fit against the upper region of the pectoralis major muscle when worn.

[0006] The beneficial effects of this invention are as follows: This solution creatively solves the contradiction between the easy fatigue and loosening of existing soft materials and the poor fit of rigid materials through a rigid support body and a specific zoned fitting design. On the one hand, the high structural strength of rigid materials (such as rigid plastics or carbon fiber composites) provides a stable skeleton for the device, which not only accommodates a larger air duct space to increase airflow, but also eliminates the loosening phenomenon caused by material creep due to long-term wear. On the other hand, by precisely dividing the support body into a first fitting area corresponding to the scapular region and a second fitting area corresponding to the upper latissimus dorsi muscle region, the rigid structure can conform to the physiological curvature of the upper back, significantly reducing the local pressure caused by a single plane. As a preferred method, the support body is integrally molded from lightweight, high-strength polycarbonate or carbon fiber materials, whose rigidity is sufficient to support the internally integrated fan or thermoelectric module without deformation, ensuring a constant cross-sectional area of ​​the internal air duct, thereby guaranteeing continuous and efficient airflow. As another preferred approach, the inner surfaces of the first and second fitting areas are pre-shaped based on back curvature data from an ergonomic database. The first fitting area is slightly convex to accommodate the movement space of the scapula, and the second fitting area is slightly concave to closely fit the latissimus dorsi muscle. This fit allows the device to remain relatively fixed in position and not wobble when the user is engaged in strenuous exercise.

[0007] Furthermore, when the support body is worn, its center line facing the user corresponds to the human spine, and several temperature adjustment mechanisms are symmetrically arranged on the support body with the center line facing the user as the axis of the support body when worn in the first and second contact areas.

[0008] The symmetrical layout centered on the human spine ensures even distribution of temperature regulation (heat dissipation or heating) across the back, avoiding discomfort or muscle spasms caused by unilateral hot or cold stimulation. Simultaneously, this symmetrical mechanical center of gravity design effectively balances the weight of the device, preventing unilateral shoulder fatigue due to a shifted center of gravity and improving comfort during extended wear. As a preferred approach, the temperature regulation mechanism is symmetrically arranged along both sides of the spine's center line. When the device is operating, the airflow or heat conduction path lengths on both sides are consistent, ensuring synchronized temperature changes on both sides of the back, making it particularly suitable for high-temperature work scenarios requiring the maintenance of core body temperature balance.

[0009] Furthermore, the number of temperature adjustment mechanisms on the support body is four, and they are symmetrically distributed in pairs in the first and second contact areas respectively. The distance between the temperature adjustment mechanism located in the first contact area and the center line of the support body facing the user when worn is greater than the distance between the temperature adjustment mechanism located in the second contact area and the center line of the support body facing the user when worn.

[0010] This design employs a differentiated layout based on the distribution characteristics of the muscles in the human back. The scapular region (first area) is wider and has more prominent bones; a wider spacing between the adjustment mechanisms avoids direct pressure on the spine and covers a larger heat dissipation surface. The upper latissimus dorsi muscle (second area) is more concentrated and contracts inwards; a narrower spacing ensures the adjustment mechanisms fit snugly against the core muscle area. This trapezoidal distribution maximizes the effective heat dissipation area of ​​the back. As a preferred approach, a set of cooling fans in the first contact area is positioned along the outer edge of the scapula, while a set of cooling fans in the second contact area is positioned along the erector spinae ridges on either side of the spine. This layout conforms to the "inverted triangle" contour of the back, ensuring that each adjustment mechanism directly faces the area where heat accumulates.

[0011] Furthermore, an arc-shaped transition area is provided between the first fitting area and the second fitting area, and the angle between the end face of the first fitting area facing the user and the end face of the second fitting area facing the user is 150-170°.

[0012] With an angle of 150-170° and a curved transition area, the brace precisely replicates the natural physiological kyphosis of the upper back. This specific angle range avoids the back being unsupported (gaps) caused by a flat design, as well as spinal compression caused by an excessively small angle. The curved transition eliminates the sharp edges at the junctions of rigid materials, preventing the edges from catching on the skin or clothing when bending over or moving the back. As a preferred method, the curved transition area uses a continuous variable curvature surface to connect the upper and lower areas. When the user performs chest expansion or hunching movements, this transition area can act as a smooth fulcrum, distributing the pressure applied to the spine and ensuring that the brace always fits snugly without restricting the natural range of motion of the spine.

[0013] Furthermore, one end of the shoulder strap is connected to the support body, and the other end is connected to a temperature regulating mechanism. The shoulder strap is made of a rigid elastic material. The shoulder strap extends from the end connected to the support body to the end connected to the temperature regulating mechanism and gradually moves towards the other shoulder strap. After expansion, the shoulder strap generates opposing torques on the support body and the temperature regulating mechanism respectively.

[0014] The shoulder straps are made of rigid, elastic materials (such as shape memory alloys or high-modulus engineering plastics) and feature an inward-curving geometry. The material's own elastic recovery force generates an active clamping torque. This torque acts like an "invisible hand," gently squeezing the front and back parts of the device towards the center of the body. Even during running and jumping, the device "grips" onto the user's shoulders, completely solving the problem of traditional soft straps easily slipping off. As a preferred method, the main body of the shoulder strap is injection-molded from a pre-bent nickel-titanium shape memory alloy skeleton. Its initial opening is smaller than the width of the human shoulder. After being stretched out, the alloy skeleton generates a persistent and constant rebound force. This torque points towards the center of the human chest cavity, thus achieving self-adaptive fixation without relying on tight buckles.

[0015] Furthermore, the shoulder strap is provided with a wire groove through which the wires electrically connected to the temperature adjustment mechanism on the support body and the temperature adjustment mechanism on the shoulder strap pass. The shoulder strap is provided with several baffles in the wire groove. The baffles cooperate with adjacent baffles or the inner wall of the shoulder strap to divide the wire groove into several independent wire management grooves.

[0016] Integrating wire channels with baffles within the rigid shoulder strap not only conceals complex circuit wiring, improving the device's neatness and aesthetics, but more importantly, it physically isolates multiple wires from tangling, abrasion, or rattling caused by vibration in confined spaces. The baffle structure enhances the shoulder strap's cross-sectional modulus, increasing its bending stiffness without adding weight. As a preferred design, the wire channels are positioned along the length of the shoulder strap, with the baffles arranged in a staggered or comb-like pattern, securing power and signal control wires into separate, independent slots. The top of the baffles is flush with the slot opening, and with the aid of a cover plate or potting compound, the wires remain within their respective tracks even during elastic deformation of the shoulder strap, preventing breakage under pressure.

[0017] Furthermore, the shoulder strap cover is provided with a soft sleeve, which covers the remaining part of the shoulder strap except for the part inserted into the support body and the front temperature adjustment mechanism.

[0018] The introduction of the soft sleeve successfully solves the problem of stiffness and friction discomfort that can occur when hard materials come into direct contact with the human body, achieving an excellent tactile feel of "rigid inside and soft outside". The soft sleeve covers all areas except for the connection interface, protecting the skin, preventing sweat and slipping, and also concealing the internal cable channel structure, thus improving the overall texture of the product. As a preferred method, the soft sleeve is made of skin-friendly liquid silicone material and slides onto the outside of the hard shoulder strap through a sleeve-like structure. Its inner wall has tiny anti-slip protrusions that fit tightly against the surface of the hard shoulder strap to prevent relative rotation of the soft sleeve. The end of the soft sleeve is designed with a tapered structure that tightly covers the base where the shoulder strap connects to the main body, preventing sweat from seeping into the hard structure and corroding the cables.

[0019] Furthermore, a dynamic fitting mechanism is provided between the temperature adjustment mechanism and the support body or shoulder strap to allow the temperature adjustment mechanism to dynamically fit onto the support body or shoulder strap. The dynamic fitting mechanism can drive the temperature adjustment mechanism to swing up and down, left and right, and move forward and backward with the center of the end face that fits onto the user as a reference. Moreover, any of the above-mentioned swinging or moving can be combined with other directions except the opposite direction to swing or move. The dynamic fitting mechanism causes the temperature adjustment mechanism to protrude from the surface of the support body, and the height of this protrusion from the surface of the support body decreases when the support body is worn on the user, and the dynamic fitting mechanism causes the temperature adjustment mechanism to tend to move towards the user.

[0020] The dynamic fit mechanism is the core solution to the contradiction between the rigid body and the dynamic human body. It gives the rigid heat sink a degree of freedom similar to a "suspension system," allowing it to be finely adjusted in all directions independently of the supporting body. When the user breathes, twists, or contracts muscles, the heat sink can remain in close contact with the skin like a floating plate, without gaps due to the rigidity of the body, ensuring stable heat exchange efficiency. As a preferred approach, this mechanism is configured as a flexible, suspended base. When the device is not worn, the base is pushed out by the elastic element; when worn, the skin compresses the base, and the accumulated elastic potential energy is converted into continuous fit pressure, ensuring that the heat dissipation surface remains firmly pressed against the skin during vigorous activities such as running, eliminating thermal resistance gaps.

[0021] Furthermore, the dynamic bonding mechanism includes a movable seat, a mounting hole, and a pushing component disposed between the mounting hole and the movable seat. The temperature regulating mechanism is installed at the center of the movable seat. The mounting hole is disposed on the support body. The movable seat is disposed inside the mounting hole, and a clearance fit is formed between the outer peripheral surface of the movable seat and the inner wall of the mounting hole. The pushing component is used to realize the movement or swing of the movable seat.

[0022] By utilizing the clearance fit between the movable base and the mounting hole, a low-friction floating environment is created, enabling the temperature regulation mechanism to not only extend and retract axially but also deflect (oscillate) within a certain angle. This structure achieves multi-degree-of-freedom motion simply and efficiently, and its compact design does not occupy excessive internal space. As a preferred approach, the movable base is designed as a rectangular or circular block structure, with its outer diameter slightly smaller than the inner diameter of the mounting hole to allow for oscillation. The pushing components are distributed around the movable base, forming multi-point elastic support. When the user's back muscles bulge locally due to movement, the movable base can tilt in the corresponding direction, automatically compensating for irregular changes in the body surface.

[0023] Furthermore, the mounting hole includes a swing groove that forms a clearance fit with the movable seat and an assembly groove for mounting the pusher. The assembly groove is symmetrically arranged on both sides of the swing groove. The movable seat has swing blocks extending from its four corners toward the assembly groove. The swing blocks cooperate with the pusher assembly to realize the movement or swing of the movable seat. The pusher assembly includes a positioning seat and a first elastic element. The positioning seat has a first positioning hole corresponding to the position of the swing block. The swing block has a second positioning hole facing the pusher assembly. The two ends of the first elastic element abut against the first positioning hole and the second positioning hole, respectively. The first positioning hole and the second positioning hole are respectively provided with a first positioning post and a second positioning post. The first elastic element is a spring and its two ends are respectively sleeved on the first positioning post and the second positioning post. The positioning seat has a guide sleeve between the two first positioning holes. The mounting hole has a guide post inserted into the guide sleeve.

[0024] This multi-positioning and guiding structure significantly improves the stability and lifespan of the dynamic fit. The cooperation between the guide posts and guide sleeves limits the disorderly swaying of the moving seat, ensuring that it mainly moves in a direction perpendicular to the human body surface; while the four corner springs and swing block structure provide a flexible restoring torque. The design of the positioning posts effectively prevents the springs from bending or falling off during repeated compression, ensuring the high reliability of the mechanism. As a preferred method, the spring stiffness coefficients at the four corners are precisely adjusted, making the moving seat's response to lateral forces non-linear: it reacts sensitively to slight touches and the support force increases rapidly under large compressions, preventing the heat sink from "bottoming out" and hitting hard. The guide posts are made of self-lubricating and wear-resistant materials, maintaining smoothness and preventing jamming even under frequent high-frequency micro-vibrations.

[0025] Furthermore, it also includes a power supply device that forms a detachable snap-fit ​​connection with the support body. The power supply device includes an interface connected to a port on the support body, an energy storage component electrically connected to the interface, and a charging port electrically connected to the energy storage component. The energy storage component is used to supply power to the temperature regulation mechanism on the shoulder strap or the support body. The power supply device is not located on the end face of the support body facing the user. The interface is located facing the support body and is hidden between the support body and the power supply device after being connected to the support body.

[0026] The detachable power supply design completely breaks through the bottleneck of battery life anxiety in traditional wearable devices. Users can achieve unlimited battery life by quickly replacing the spare battery module without stopping to charge. Even more unique is the hidden interface design, which encases the fragile electrical connection points between the robust main body and the battery shell, effectively preventing poor contact caused by external dust, rain, and impacts, greatly improving safety for outdoor use. As a preferred method, the power supply device is designed as a flat module with its electrode contacts recessed inside the module. When it slides into the slot supporting the main body, the contacts automatically align and conduct with the elastic probes on the main body. The entire connection interface is completely covered by the module shell, forming a streamlined, integrated design with no exposed connectors.

[0027] Furthermore, the two ends of the power supply device facing the support body are respectively snapped onto the support body, and one or both ends can be released from the snapping relationship with the support body.

[0028] The double-clamping design provides a dual mechanical lock for heavier battery modules, ensuring they won't detach due to inertia during vigorous activity. The design logic of one fixed end and one removable end ensures both a secure connection and simplified disassembly, meeting the ergonomic requirements for one-handed operation. As a preferred method, the lower end of the battery module uses an insert-type fixed-lock, while the upper end uses a spring-loaded movable latch for secure fastening. During replacement, the user simply presses the unlocking mechanism at the upper end, and the battery module automatically springs up at a certain angle due to the internal pre-compression spring, making it easy for the user to grasp and remove. The entire process is smooth and tool-free.

[0029] Furthermore, the power supply device is symmetrically provided with fixing buckles at one end facing the device body, and the support body is provided with positioning buckle holes corresponding to the fixing buckles.

[0030] The symmetrical locking buckle design significantly enhances torsional resistance. When the device is subjected to a lateral impact, the two fixing points can share the shear force, preventing breakage at the connection root. Simultaneously, the symmetrical structure has a foolproof function, assisting users in accurate alignment by feel even during blind operation (such as when carrying it on their back). As a preferred method, the locking buckle is designed with a barbed structure made of high-strength POM (polyoxymethylene) material. When inserted into the positioning hole, the barb hooks onto the reinforcing ribs of the inner wall of the housing, preventing axial removal unless rotated at a specific angle or the release button is pressed, ensuring absolute reliability of the connection.

[0031] Furthermore, the power supply device is provided with a pressing buckle at one or both ends of the end face facing the support body. The support body is provided with a fixing buckle hole corresponding to the pressing buckle. The power supply device is provided with a buckle hole for the pressing buckle to move inside it. The pressing buckle includes a pressing member. A buckle is provided on the side of the pressing member corresponding to the buckle hole. A second elastic member is provided on the side of the pressing member facing the buckle hole to abut against it. The other end of the second elastic member abuts against the bottom of the buckle hole and the second elastic member is used to prevent the buckle from coming out of the fixing buckle hole.

[0032] This push-button latch features an built-in elastic element that enables automatic reset and locking, providing active safety for battery fixation. The elastic element consistently applies a locking force to the latch, preventing it from dislodging due to its own weight or inertia, even under strong vibrations. The pressing operation is intuitive and provides good tactile feedback (a "click") to confirm the locked state. As a preferred design, the press element has an anti-slip texture and is located in an easily accessible position on the side or top of the battery module. The internal second elastic element is a compression spring. When pressed, the spring compresses, causing the latch to retract; upon release, the spring instantly rebounds, pushing the latch into the locking groove of the fixing hole. The entire mechanism is encapsulated within the battery housing, providing dust and sand protection.

[0033] Furthermore, an auxiliary adsorption component is provided on the end face of the power supply device facing the device body. The auxiliary adsorption component is used to enhance the connection between the power supply device and the support body. The support body is provided with a recessed auxiliary positioning hole. The auxiliary adsorption component protrudes from the end face of the power supply device facing the device body and is magnetic. The auxiliary adsorption component and the auxiliary positioning hole cooperate to form a magnetic adsorption force.

[0034] Magnetic-assisted adsorption and mechanical clips form a perfect combination of "coarse positioning + fine locking". During installation, the magnetic force guides the battery module to automatically move towards the correct position and adsorb, solving the problem of alignment difficulties, especially greatly improving convenience when operating blindly from the back. At the same time, the magnetic adsorption force can also eliminate the slight wobble caused by mechanical tolerances, improving the overall tightness of the assembly. As a preferred method, the auxiliary adsorption component uses a powerful neodymium iron boron magnet, which is embedded in the positioning boss of the power supply unit, and the bottom of the corresponding auxiliary positioning hole is inlaid with an iron piece or a magnet of opposite poles. When the two are close to a distance of 2-3cm, the magnetic force quickly pulls them into place, at which point the mechanical clip is perfectly aligned with the locking hole, and the user only needs to press lightly to complete the final mechanical double locking.

Detailed Implementation

[0036] An embodiment of the present invention provides a wearable human body temperature regulation device, such as... Figure 1-14 As shown: A support body 1, injection molded from a rigid material (such as polycarbonate or carbon fiber reinforced plastic), is provided with several ventilation holes 10 extending through its thickness to enhance airflow to the back. Two shoulder straps 2 are symmetrically connected to the end of the support body 1 facing the head, with the ends of the two shoulder straps 2 respectively connected to a front chest temperature regulation mechanism 31. Four back temperature regulation mechanisms 32 are also installed on the support body 1. For better ergonomic fit, the support body 1 is structurally divided into a first fitting area 11 and a second fitting area 12, connected by a smoothly transitioning arc-shaped transition area 13. In a natural wearing state, the centerline of the support body 1 corresponds to the human spine. The first fitting area 11 is slightly convex to fit the scapular region, and the second fitting area 12 is slightly concave to fit the upper latissimus dorsi muscle region. An angle of 150-170° is formed between the end faces of the first fitting area 11 and the second fitting area 12 facing the user, conforming to the physiological kyphotic curve of the upper back. The four back temperature regulation mechanisms 32 are arranged in pairs, symmetrically distributed around the center line of the support body 1. Among them, the two back temperature regulation mechanisms 32 located in the first contact area 11 have a wider gap and fit the outer side of the scapula; the two back temperature regulation mechanisms 32 located in the second contact area 12 have a narrower gap and fit the muscle bulges on both sides of the spine, forming an overall trapezoidal distribution.

[0037] To address the issue of stiffness in the rigid body, the back temperature adjustment mechanism 32 and / or the front chest temperature adjustment mechanism 31 are not directly fixed to the end of the support body 1 or the shoulder strap 2, but are instead connected via a dynamic fitting mechanism 4. Taking the back temperature adjustment mechanism 32 as an example, it includes a heat dissipation patch 321 and a cooling fan 322, with heat dissipation fins 323 integrated on the cooling fan 322. The support body 1 has mounting holes 14 corresponding to the positions of each back temperature adjustment mechanism 32. Each mounting hole 14 includes a central swing groove 141 and symmetrically distributed mounting grooves 142 on both sides. The dynamic fitting mechanism 4 includes a movable seat 41 placed within the mounting hole 14, with the heat dissipation patch 321 fixed to the center of the movable seat 41. A gap is left between the outer periphery of the movable seat 41 and the swing groove 141, forming a clearance fit that allows the movable seat 41 to tilt and swing. Swing blocks 411 extend from the four corners of the movable seat 41 and extend into the mounting grooves 142. A pushing assembly 42 is provided between the mounting hole 14 and the movable seat 41. This assembly includes a positioning seat 421 fixed to the back of the support body 1, a first elastic element 422 (spring), and a guide structure. The positioning seat 421 has a first positioning hole 4211, and the swing block 411 has a second positioning hole 4111. The two ends of the first elastic element 422 are respectively sleeved on a first positioning post 4212 located in the first positioning hole 4211 and a second positioning post 4112 located in the second positioning hole 4111. A guide sleeve 423 is provided in the center of the positioning seat 421. In conjunction with the guide post 424 inserted therein, the movable seat 41 is restricted to move mainly in a direction perpendicular to the back of the human body, while allowing it to swing within a certain angle. This structure allows the back temperature regulation mechanism 32 to protrude from the surface of the support body 1 under normal conditions and to retract and tilt adaptively when pressed.

[0038] The shoulder strap 2 is integrally molded from a rigid elastic material made of POK, nylon, or elastic metal. This type of material has excellent elastic recovery, fatigue resistance, and aging resistance, effectively preventing loss of elasticity caused by long-term repeated deformation. Its shape is designed to gradually taper inward from the connecting end to the end, generating a counter-torque pointing towards the center of the human chest cavity after expansion when worn, achieving active clamping. The shoulder strap 2 has a wire channel 21 extending along its length inside, with baffles 22 set at intervals in the channel, dividing the wire channel 21 into multiple independent cable management channels 23 to isolate the power cord and control cord. The shoulder strap 2 is covered with a skin-friendly soft sleeve 23 (such as liquid silicone). The soft sleeve 23 only covers the middle section of the shoulder strap 2, avoiding the connecting end of the shoulder strap 2 into the support body 1 and the end connected to the front chest temperature adjustment mechanism 31, ensuring the stability of the mechanical connection and facilitating disassembly and washing.

[0039] The exposed portion of the shoulder strap 2 facing the human body, beyond the support body 1 and the chest temperature regulation mechanism 31, is provided with a first arc surface 24, a second arc surface 25, and a third arc surface 26 in sequence. One end of the first arc surface 24 is connected to the outer wall of the support body 1, and the other end is connected to one end of the second arc surface 25. The other end of the second arc surface 25 is connected to one end of the third arc surface 26, and the other end of the third arc surface 26 is connected to the outer wall of the chest temperature regulation mechanism 31. The first arc surface 24 corresponds to the back area of ​​the human body, the second arc surface 25 spans the shoulder area of ​​the human body, and the third arc surface 26 corresponds to the front end area of ​​the human body's torso. The first arc surface 24, the second arc surface 25, and the third arc surface 26 can all be composed of a single complete arc surface, or they can be composed of multiple small arc surfaces with different curvatures spliced ​​together. In the embodiment where the first arc surface 24 and the third arc surface 26 are composed of multiple small arc surfaces with different curvatures, the radius of curvature of each small arc surface of the first arc surface 24 and the third arc surface 26 is gradually reduced towards the support body 1 and the chest temperature adjustment mechanism 31, respectively. In specific implementation, the radius of curvature of the first arc surface 24 is selected as a value between 22-55mm, the radius of curvature of the second arc surface 25 is selected as a value between 58-90mm, and the radius of curvature of the third arc surface 26 is selected as a value between 50-80mm. Through the matching of the arc surface structure and size, the exposed part of the shoulder strap 2 is highly adapted to the physiological contour of the human body.

[0040] The device is powered by a detachable power supply unit 5. The power supply unit 5 includes a housing and an internal energy storage component (not shown), with a charging port 52. The power supply unit 5 is installed on the side of the support body 1 away from the human body, with an interface 53 hidden between the two surfaces and connected to the port 18 of the support body 1. The connection structure uses a "bottom-hook, top-lock" design with magnetic assistance: the lower end of the power supply unit 5 has symmetrically arranged barbed fasteners 54 that engage with positioning fastener holes 15 on the support body 1; the upper end has a pressing fastener 55 that engages with fixing fastener holes 16 on the support body 1. The pressing fastener 55 includes a pressing element 551 and a fastener 552, with a second elastic element 553 inside that always pushes the fastener 552 into the locked position. Furthermore, the surface of the power supply unit 5 has protruding magnetic auxiliary adsorption elements 56 that correspond to recessed auxiliary positioning holes 17 on the support body 1, using magnetic attraction to assist in alignment.

[0041] The power supply device 5 is provided with a latching hole 57 for the pressing latching member 55 to move within it. A latching member 554 is provided on the side of the pressing member 551 corresponding to the latching hole 57. A second elastic member 553 is provided on the side of the pressing member 551 facing the latching hole 57, and the other end of the second elastic member 553 abuts against it. The second elastic member 553, like a spring, is used to provide elastic force to prevent the latching member 554 from coming out of the fixed latching hole 16. When the user presses the pressing member 551, the latching member 552 retracts to release the latch. To strengthen the connection between the second elastic member 553, the pressing member 551, and the latching hole 57, a third positioning post 555 and a fourth positioning post 571 are provided on the pressing member 551 and the latching hole 57, respectively. The two ends of the second elastic member 553 (which is a spring) are respectively sleeved on the third positioning post 555 and the fourth positioning post 571. Limiting posts 554 are provided on both sides of the pressing member 551. The snap hole 57 is provided with a limiting groove 572 corresponding to the limiting post 554. The limiting post 554 and the limiting groove 572 cooperate to prevent the pressing member 551 from coming out of the snap hole 57.

[0042] The working principle of this invention is as follows: When the user wears the device, the rigid shoulder straps 2 are stretched open, generating a rebound torque that presses the front chest temperature regulating mechanism 31 and the back temperature regulating mechanism 32 tightly against the front and back sides of the body to prevent slippage. The rigid structure of the support body 1 ensures that the air duct space is not compressed. When the support body 1 fits against the back, if the user's back curve is uneven or in motion (such as bending over or swinging arms), the back temperature regulating mechanism 32 is pressed by the skin, pushing the movable seat 41 in the dynamic fitting mechanism 4 to overcome the resistance of the first elastic element 422 and retract into the mounting hole 14. At this time, the first elastic element 422 accumulates elastic potential energy and continuously applies pressure towards the human body. At the same time, by utilizing the gap fit between the movable seat 41 and the swing groove 141, the back temperature regulating mechanism 32 can swing and tilt slightly up, down, left, and right following the muscle undulations, always maintaining a tight fit between the end face and the skin, eliminating air gap thermal resistance, and greatly improving heat exchange efficiency.

[0043] When the battery needs to be replaced, the user does not need to remove the device. Simply press the pressing piece 551 on the top of the power supply device 5 with your back hand, compressing the second elastic piece 553 to disengage the buckle 552 from the fixing buckle hole 16. At this time, the magnetic force of the auxiliary adsorption piece 56 is insufficient to resist the weight of the power supply device 5 itself or the disassembly force. The user can then gently lift upwards to release the hook of the lower fixing buckle 54 and remove the power supply device 5. During installation, the magnetic auxiliary adsorption piece 56 will guide the power supply device 5 to automatically adsorb and align with the auxiliary positioning hole 17. Subsequently, the buckle structure will automatically lock under the pressing or pushing action, and the interface 53 will then be connected, enabling quick battery replacement under blind operation.

[0044] The above embodiments are merely one preferred embodiment of the present invention. Ordinary variations and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included within the protection scope of the present invention.
