Description

Technical Field

[0001] This application relates to the field of clothing technology, and more particularly to a wearable device. Background Technology

[0002] Down jackets and other clothing typically consist of an outer fabric and an inner lining forming a sandwich structure. The sandwich is divided into multiple relatively independent down cavities by quilting, stitching, or the addition of dividers to separate the filling and maintain its fluffy shape. This creates a relatively stable air layer between the fabric layers and around the cavities to achieve insulation. However, such products are prone to sweating and lack comfort. Summary of the Invention

[0003] One objective of this application is to provide a wearable that addresses the technical problem in the related art of wearables being unable to improve breathability while maintaining thermal insulation.

[0004] To achieve the above objectives, this application provides a wearable device comprising: a base fabric; and a plurality of heat-insulating units arranged on one side of the base fabric, wherein the plurality of heat-insulating units includes at least one movable unit, the movable unit having a free side that is movable relative to the base fabric, and an openable ventilated gap being formed between the free side of the movable unit and an adjacent heat-insulating unit, the opening degree of which changes as the free side of the movable unit moves.

[0005] The wearable device of this application includes a base fabric and a plurality of insulation units arranged on one side of the base fabric, wherein at least one insulation unit is a movable unit, and the movable unit includes a free side that forms an openable ventilated gap with the adjacent insulation unit. Since the opening degree of the ventilated gap changes with the movement of the free side, when the free side is in different moving positions, the ventilated gap presents different opening degrees accordingly, so as to realize the variation of the gas exchange capacity of the wearable device under different states.

[0006] In related technologies, insulation units are typically arranged in a relatively fixed manner, and the relative relationship between adjacent units remains essentially constant, making it difficult for the ventilation path and ventilation volume to change with the wearing state. Compared with related technologies, this application incorporates a movable unit with a free side, utilizing the mobility of the free side to create an openable and variable-aperture ventilation gap between it and adjacent insulation units. This allows the ventilation capacity to change with the movement of the free side, rather than being a single fixed value. Therefore, on the one hand, when the ventilation gap opening is small, the gap between the free side of the movable unit and adjacent insulation units tends to decrease, which helps reduce gas exchange and maintain insulation; on the other hand, when the ventilation gap opening increases, a more obvious ventilation channel can be formed between adjacent insulation units, which is more conducive to expelling heat and moisture accumulated during wearing, thus improving wearing comfort. Therefore, the garment of this application achieves both insulation and ventilation performance without relying on additional ventilation components.

[0007] According to one embodiment of this application, in a static state, the free side of the movable unit overlaps or abuts against the adjacent insulation unit, and the air gap is closed; when subjected to external force, the free side deviates from the adjacent insulation unit, and the air gap is opened.

[0008] When the free side of the active unit is stationary, it overlaps or abuts against the adjacent insulation unit, keeping the ventilation gap closed. This reduces air exchange between the insulation units and inhibits heat loss, thus maintaining the garment's insulation performance. However, when the garment is subjected to external force during wear, the free side deviates from the adjacent insulation unit, opening the ventilation gap and creating a vent. This provides a channel for the expulsion of heat and moisture, enhancing breathability and moisture wicking, and reducing stuffiness. Therefore, this embodiment of the garment achieves a dynamic thermo-moisture regulation effect—prioritizing insulation when stationary and breathability when under force or in motion—without requiring a power source.

[0009] According to one embodiment of this application, the base fabric is provided with air vents, and the air vents are at least located in the area corresponding to the air vent gap, and the air vent gap and the air vents are connected to form an air vent passage.

[0010] In this embodiment, ventilation holes are provided on the base fabric, and these holes are arranged at least in the area corresponding to the ventilation gaps. This allows the openable ventilation gap formed between the free side of the movable unit and the adjacent insulation unit to communicate with the ventilation holes in the base fabric, thereby establishing a clear ventilation path between the two sides of the garment. This structure makes it easier for hot air and moisture to escape through the ventilation holes along a predetermined path, improving the efficiency of local ventilation.

[0011] According to one embodiment of this application, the diameter D of the vent hole is 0.6 mm to 1 mm.

[0012] According to one embodiment of this application, a reserved space is also formed between the surface or bottom of the active unit and the adjacent insulation unit. The air gap is connected to the air vent through the reserved space, and the reserved space narrows as it moves away from the base fabric.

[0013] As the reserved space narrows as it moves away from the base fabric, the moving units are more likely to cover, overlap, or abut against adjacent insulation units when stationary. This causes the air gap between adjacent insulation units to decrease or even close, reducing unexpected air leakage and heat loss, and thus achieving better insulation performance when stationary.

[0014] According to one embodiment of this application, the active unit includes a bottom surface facing the base fabric and a surface facing away from the base fabric, with a periphery formed between the bottom surface and the surface, and the free side being the portion of the periphery that has a gap with the base fabric, and a reserved space formed between the bottom surface and the adjacent insulation unit.

[0015] According to one embodiment of this application, a plurality of active units are arranged sequentially along a first direction, and the free sides are all facing the same direction of the first direction.

[0016] According to one embodiment of this application, when the garment is worn, the first direction extends vertically, and the free side hangs down naturally under the action of gravity.

[0017] According to one embodiment of this application, the active unit is located on the side of the base fabric facing the wearer.

[0018] According to one embodiment of this application, the plurality of insulation units further includes at least one fixing unit, the periphery of which is connected to the base fabric.

[0019] According to one embodiment of this application, a movable unit is configured on the target area of ​​the base fabric corresponding to the back of the human body.

[0020] According to one embodiment of this application, the target area is polygonal, the periphery of the active unit is polygonal, the free side is at least one side of the periphery of the active unit that is on the lower side in the wearing state, and multiple active units cover the target area in the static state.

[0021] According to one embodiment of this application, when the garment is worn, the ventilation gap extends in the horizontal direction.

[0022] According to one embodiment of this application, the insulation unit is a down bale filled with down.

[0023] Other advantages, objectives and features of this application will be partly apparent from the description below, and partly understood by those skilled in the art through study and practice of this application. Attached Figure Description

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] Before introducing the embodiments of this application, the relevant technologies involved in this application will be introduced first.

[0030] Down jackets typically use an outer fabric and an inner lining to form a sandwich structure. The sandwich structure is divided into multiple independent down cavities by quilting, stitching, or dividers to limit the migration of the filling and maintain a stable loft. Air forms a relatively static insulating layer between the fabric layers and around the cavities, thus achieving the function of keeping the body warm and protected from the cold.

[0031] To further improve wearing comfort and thermal moisture management performance, related technologies have proposed improvements to enhance local or overall breathability and moisture wicking capacity based on the thermal insulation structure. For example, by selecting textile materials with certain moisture permeability and breathability, or by setting microporous structures on fabrics or coating materials, water vapor can be diffused outward and heat and moisture exchange can be accelerated, thereby alleviating stuffiness and dampness caused by exercise or environmental changes to a certain extent.

[0032] However, the aforementioned improvements still present a challenge in practical applications: achieving both breathability and warmth retention is difficult. Increased breathability often comes at the cost of weakening the effective insulating air layer, leading to faster localized heat loss and a decline in overall insulation performance. Furthermore, when the heat dissipation differences in different areas of the garment do not align with individual comfort needs, localized overcooling or fluctuations in comfort can occur, affecting the overall wearing experience. Therefore, how to maintain the insulation performance of down jackets and other wearables while achieving effective and controllable ventilation and moisture wicking, and minimizing the negative impact of enhanced breathability on overall warmth retention, has become a pressing technical problem that needs to be solved in this field.

[0033] In order to solve the technical problems existing in the above-mentioned related technologies, this application discloses the following technical solutions.

[0034] Please refer to Figures 1 to 3 This application discloses a wearable device, including: a base fabric 10; a plurality of heat-insulating units 20 arranged on one side of the base fabric 10, wherein the plurality of heat-insulating units 20 includes at least one movable unit 21, the movable unit 21 having a free side 211 that is movable relative to the base fabric 10, and an openable breathable gap 31 being formed between the free side 211 of the movable unit 21 and the adjacent heat-insulating unit 20, the opening degree of the breathable gap 31 changing with the movement of the free side 211 of the movable unit 21.

[0035] The wearable device of this application includes a base fabric 10 and a plurality of heat-insulating units 20 arranged on one side of the base fabric 10, wherein at least one heat-insulating unit 20 is a movable unit 21, and the movable unit 21 includes a free side 211 that forms an openable ventilation gap 31 with the adjacent heat-insulating unit 20. Since the opening degree of the ventilation gap 31 changes with the movement of the free side 211, when the free side 211 is in different active positions, the ventilation gap 31 presents different opening degrees accordingly, so as to realize the change of the gas exchange capacity of the wearable device under different states.

[0036] The movable unit 21 includes a bottom surface 213 facing the base fabric 10 and a surface 212 facing away from the base fabric 10. A periphery is formed between the bottom surface 213 and the surface 212. The free side 211 is the portion of the periphery that has a gap with the base fabric 10. That is, the periphery of the movable unit 21 is not completely fixed to the base fabric 10, and the movable portion that is not completely fixed is the free side 211.

[0037] In related technologies, the entire periphery of the insulation unit 20 is typically set in a relatively fixed manner, and the relative relationship between adjacent units is basically constant, making it difficult for the ventilation path and ventilation volume to change with the wearing state. Compared with related technologies, this application sets up a movable unit 21 with a free side 211, and utilizes the mobility of the free side 211 to form an openable and variable ventilation gap 31 between it and the adjacent insulation unit 20, so that the ventilation capacity is no longer a single fixed value, but can change with the movement of the free side 211. Thus, on the one hand, when the opening of the ventilation gap 31 is small, the gap between the free side 211 of the movable unit 21 and the adjacent insulation unit 20 tends to decrease, which is conducive to reducing gas exchange and maintaining the insulation state; on the other hand, when the opening of the ventilation gap 31 increases, a more obvious ventilation channel can be formed between the adjacent insulation units 20, which is more conducive to the discharge of heat and moisture accumulated during wearing, improving wearing comfort. Therefore, the wearable of this application takes into account both insulation performance and ventilation performance without relying on additional ventilation components.

[0038] It should be understood that the opening of the ventilation gap 31 in this application changes with the movement of the free side 211 of the movable unit 21, but this is not a random change. When worn, the insulation unit 20 is subject to gravity. In a static state, the ventilation gap 31 tends to maintain a stable, relatively small opening or even be closed. However, when the wearer moves, the garment is subjected to external forces, and the free side 211 gains the momentum to move, causing the ventilation gap 31 to expand accordingly. This is consistent with the need for better insulation in a static state and better ventilation in a moving state.

[0039] It should also be noted that the "opening degree" referred to in this application should be understood as the degree to which the air gap 31 is open. The larger the opening degree, the better the ventilation effect of the air gap 31 and the smaller the air flow resistance. In addition to the obvious positive correlation between the opening degree and the ventilation effect, there are no additional limitations. The opening degree should not be understood as the opening angle of the free side 211 or other specific structures or parameters to limit the scope of protection of this application.

[0040] For example, the insulation unit 20 can be a fleece pouch, including a fleece sleeve 23 and insulation material 24 such as down, feathers, and / or down-like fibers filled inside the fleece sleeve 23. Alternatively, the insulation unit 20 can also be composed of a fabric layer with a certain thickness, such as thick cotton, wadding material, and / or multi-layer composite cotton, to form a unit structure with insulation properties. The connection method between the insulation unit 20 and the base fabric 10 can also be selected according to process requirements, and can be sewn connection, heat-pressed connection, or adhesive connection; furthermore, the insulation unit 20 can be independently processed and then connected to the base fabric 10, or it can be a bag fabric sewn onto the base fabric 10, so that the base fabric 10 closes the bag opening, and the bag fabric is filled with insulation material 24, that is, the base fabric 10 constitutes all or part of the bottom surface 213.

[0041] According to one embodiment of this application, in a static state, the free side 211 of the movable unit 21 overlaps or abuts against the adjacent insulation unit 20, and the air gap 31 is closed; when subjected to external force, the free side 211 deviates from the adjacent insulation unit 20, and the air gap 31 is opened.

[0042] When the free side 211 of the active unit 21 is stationary, it overlaps or abuts against the adjacent insulation unit 20, keeping the ventilation gap 31 closed. This reduces air exchange between the insulation units 20 and inhibits heat loss, thus maintaining the insulation performance of the garment. However, when the garment is subjected to external force during wear, the free side 211 deviates from the adjacent insulation unit 20, causing the ventilation gap 31 to open and form a vent, providing a channel for the expulsion of heat and moisture, enhancing breathability and moisture wicking, and reducing stuffiness. Therefore, the garment of this embodiment achieves a dynamic thermo-humidity regulation effect—prioritizing insulation when stationary and breathability when subjected to force or in motion—without a power source.

[0043] According to one embodiment of this application, the base fabric 10 is provided with air holes 32, and the air holes 32 are at least provided in the area corresponding to the air gap 31. The air gap 31 and the air holes 32 are connected to form an air passage 30.

[0044] The area corresponding to the air gap 31 can be understood as the area corresponding to the union of the projections of all possible variations of the air gap 31 onto the base fabric 10.

[0045] In this embodiment, the base fabric 10 is provided with ventilation holes 32, and the ventilation holes 32 are arranged at least in the area corresponding to the ventilation gap 31, so that the openable ventilation gap 31 formed between the free side 211 of the movable unit 21 and the adjacent heat preservation unit 20 can communicate with the ventilation holes 32 of the base fabric 10, thereby establishing a clear ventilation passage 30 between the two sides of the wearer. The above structure makes it easier for hot air and water vapor to be discharged through the ventilation holes 32 along the predetermined path, improving the efficiency of local ventilation.

[0046] The ventilation holes 32 are exemplary in the form of a regular array / matrix or a non-uniform matrix. Those skilled in the art can refer to the ventilation holes 32 in related technologies for configuration.

[0047] According to one embodiment of this application, the diameter D of the vent 32 is 0.6 mm to 1 mm.

[0048] When the pore size is too small, the effective flow cross-sectional area of ​​the vent 32 is limited, increasing the resistance to gas exchange and making it difficult for hot air and water vapor to escape smoothly, resulting in relatively insignificant local ventilation. When the pore size is too large, strong convection ventilation is more likely to form at the vent 32, leading to faster local heat loss and weakening the insulation effect. Limiting the diameter D of the vent 32 to 0.6mm to 1mm helps to achieve a more suitable balance between ventilation efficiency and thermal insulation stability. This ensures the formation of an effective ventilation passage 30 and improves moisture wicking and heat dissipation capabilities while reducing the degree of damage to the insulation air layer caused by the vent 32, making ventilation and insulation more coordinated during wear.

[0049] According to one embodiment of this application, a reserved space 33 is also formed between the surface or bottom surface of the active unit 21 and the adjacent heat preservation unit 20. The air gap 31 is connected to the air hole 32 through the reserved space 33. The reserved space 33 narrows as it moves away from the base fabric 10.

[0050] As the reserved space 33 narrows as it moves away from the base fabric 10, the movable unit 21 is more likely to cover, overlap or abut against the adjacent insulation unit 20 when stationary, thereby causing the air gap 31 between adjacent insulation units 20 to tend to decrease or even close, reducing unexpected air leakage and heat loss, which is conducive to obtaining a better insulation effect when stationary.

[0051] It should be understood that the narrowing referred to in this embodiment means that the cross-sectional area of ​​the reserved space 33 is reduced in any way, and is not limited to the narrowing in the direction of the arrangement of the active units 21 as shown in the figure.

[0052] According to one embodiment of this application, a reserved space 33 is formed between the bottom surface 213 and the adjacent insulation unit 20.

[0053] Since a reserved space 33 is formed between the bottom surface 213 and the adjacent insulation unit 20, the air gap 31 can be connected to the air vent 32 on the base fabric 10 through the reserved space 33, thereby making the geometry of the air passage 30 clearer, which is conducive to maintaining a smaller degree of opening in a static state to reduce air leakage and maintain the insulation performance.

[0054] According to one embodiment of this application, a plurality of active units 21 are arranged sequentially along a first direction, and the free sides 211 all face the same orientation of the first direction.

[0055] Multiple movable units 21 are arranged sequentially along a first direction, with the free sides 211 of each movable unit 21 facing the same side of the first direction. This creates a consistent upward lifting trend of the multiple movable units 21 in the arrangement direction, making it easier for adjacent movable units 21 to form a forward overlapping or stacking relationship. The free sides 211 of adjacent units can achieve relative displacement in the same direction during static or force-driven movements, reducing mutual collisions, folding interference, etc., and avoiding interference between adjacent units that affects the stability of the closure and opening of the air gap 31. This, in turn, helps maintain the orderliness of the overall structural form and the consistency of the ventilation effect.

[0056] According to one embodiment of this application, when the wearable is in the wearing state, the first direction extends in the vertical direction, and the free side 211 hangs down naturally under the action of gravity.

[0057] When worn, the movable units 21 are arranged vertically in sequence, and the free side 211 of the movable units 21 hangs down naturally under the action of gravity. This allows the free side 211 to tend to be close to, overlap or abut against the adjacent insulation unit 20 when there is no external force or the human body movement is small. This makes the ventilation gap 31 keep a small opening or even in a closed state under normal conditions, reducing unnecessary air exchange between the inside of the garment and the outside world, reducing the possibility of heat loss through convection through the gap, and helping to maintain a more stable insulation effect in static or low-activity scenarios.

[0058] Furthermore, the active unit 21 is located on the side of the base fabric 10 facing the wearer.

[0059] The movable unit 21 is located on the side of the base fabric 10 facing the wearer, and the free side 211 of the movable unit 21 hangs down close to the adjacent insulation unit 20 in normal conditions. This causes the opening shape of the breathable gap 31 to tilt upwards and outwards from the wearer's side. As a result, the moisture and heat generated by the human body rises and flows spontaneously, making it easier to be guided by the breathable gap 31 and expelled outwards, thereby improving the initiative and efficiency of moisture wicking and heat dissipation, and improving the stuffiness without significantly increasing air leakage in a static state.

[0060] Of course, it should be understood that although the structural design in this embodiment guides the upward flow of hot and humid sweat, it does not mean that the exhaust flow direction in this application is necessarily upward or inclined upward. Since the wearer and the garment are in a state of intense dynamics during exercise, the exhaust of hot air is not necessarily entirely upward under the action of density difference. It can also be horizontally or even downward along the ventilation gap 31. The specific situation should also take into account the setting of the ventilation gap 31 and the movement conditions.

[0061] According to one embodiment of this application, the plurality of insulation units 20 further includes at least one fixing unit 22, the periphery of which is connected to the base fabric 10.

[0062] In this embodiment, at least one fixing unit 22 is provided in each of the multiple insulation units 20, which is peripherally connected to the base fabric 10. That is, the garment does not use openable movable units 21 in all areas, but rather movable units 21 are arranged in key heat dissipation areas where enhanced ventilation and moisture removal are needed, while fixed units 22 are used in other areas to maintain the conventional clothing insulation structure. Thus, controllable ventilation can be achieved locally, while maintaining a relatively stable loft and insulation state in non-heat dissipation key areas. Furthermore, the peripheral connection method of the fixing unit 22 has high compatibility with common quilting partitioning or fixing molding processes of down jackets, cotton-padded jackets, etc., which facilitates modular combination and adaptation based on existing product structures. For example, the peripheral fixing unit 22 can be made by sandwiching insulation material 24 between the outer fabric and the base fabric 10, and then connecting the outer fabric and the base fabric 10 with grid-like stitching, thereby dividing and fixing multiple fixing units 22 to achieve peripheral fixation.

[0063] According to one embodiment of this application, an active unit 21 is configured on the target area of ​​the base fabric 10 corresponding to the back of the human body.

[0064] Considering that the back is a region where humans are prone to sweating and accumulating heat and moisture during daily wear, this embodiment configures the target area of ​​the base fabric 10 corresponding to the human back as the active unit 21 area, which allows the breathable gap 31 and its connected breathable passage 30 to be closer together. When the wearer is stationary or slightly active, this area can achieve a certain degree of heat preservation by adhering to the adjacent heat preservation unit 20 through the free side 211. When walking, raising the arm, or when the back moves, the active unit 21 is more likely to generate relative displacement and open the breathable gap 31, allowing the sweat and heat generated on the back to be discharged more promptly, reducing the stickiness and stuffiness caused by heat and moisture retention, thereby improving the thermal and moisture comfort of the back area.

[0065] According to one embodiment of this application, the target area is polygonal, the periphery of the active unit 21 is polygonal, the free side 211 is at least one side of the periphery of the active unit 21 that is on the lower side in the wearing state, and the multiple active units 21 cover the target area in the static state.

[0066] On the one hand, the free side 211 is at least one of the lower sides of the perimeter of the movable unit 21 when worn, which allows the free side 211 to tend to hang down naturally under the action of gravity and overlap with the adjacent insulation unit 20. This makes the ventilation gap 31 keep a small opening or even close when stationary, reducing cold air convection and helping to maintain the insulation effect of the target area. On the other hand, when stationary, multiple movable units 21 cover the target area, which can maintain the overall insulation continuity of the target area while ensuring controllable ventilation and reducing the fluctuation of body feeling caused by local openings.

[0067] The periphery of the target area and the activity unit 21 can be a rectangle, a regular trapezoid, or an inverted trapezoid. For example, in a loose-fitting garment, the periphery of the target area and the activity unit 21 can be configured as a regular trapezoid or a rectangle, while in a fitted garment, the periphery of the target area and the activity unit 21 can be configured as an inverted trapezoid.

[0068] For example, in a preferred embodiment of this application, the target area is trapezoidal, the periphery of the active unit 21 is trapezoidal, the free side 211 is at least the lower bottom of the periphery of the active unit 21, and in the static state, a plurality of active units 21 of gradually increasing size are arranged sequentially between the upper bottom and the lower bottom of the target area along the height direction of the target area and cover the target area; when the wearable is worn, the target area and the active unit 21 are both with the upper bottom on top and the lower bottom on the bottom.

[0069] Considering that the shoulder joint has the widest range of motion and the highest flexibility in the human body, the upper back of the clothing is more easily pulled during movements such as raising the arm, extending forward, and abducting, causing the corresponding movable unit 21 to tend to open more. Therefore, in this embodiment, the movable unit 21 is set to gradually increase in size from top to bottom along the height direction of the target area. Correspondingly, the effective exhaust area of ​​the ventilation gap 31 also gradually increases from top to bottom: although the upper unit is pulled more strongly, it is not easy to form an excessively large opening due to its smaller size, thereby reducing the risk of local air leakage and coldness in the upper back; the lower unit is pulled relatively less, but the larger unit size compensates for the exhaust capacity, avoiding insufficient exhaust in the lower part. This makes the heat dissipation and moisture wicking effect in the target area more balanced and stable from top to bottom, reducing local excessive or insufficient heat dissipation caused by differences in movement.

[0070] In a preferred embodiment, the upper and lower bottoms of the periphery of the movable unit 21 are both free sides 211, and the two waists of the periphery of the movable unit 21 are fixedly connected to the base fabric 10.

[0071] According to one embodiment of this application, when the wearable is in the wearing state, the ventilation gap 31 extends in the horizontal direction.

[0072] When worn, the ventilation gap 31 extends horizontally, which makes it easier for the free side 211 of the movable unit 21 to hang down evenly along the entire horizontal edge under its own weight and fit into the adjacent insulation unit 20. This causes the ventilation gap 31 to maintain a small opening or even tend to close when stationary, reducing heat loss caused by air convection and making the insulation effect more reliable.

[0073] Obviously, the air gap 31 in this application is for illustration only; please refer to... Figures 4 to 8 Those skilled in the art can adjust the arrangement of the ventilation gaps 31 according to actual needs and experience. For example, the ventilation gaps 31 can be placed under the armpits or at the hem of the clothing. The size of the insulation unit 20 and the density of the ventilation gaps 31 can also be adjusted as needed. Please refer to... Figure 9 and Figure 10 As shown, the structure of this application can also be applied to different wearable garment designs.
