Description

Technical Field

[0001] This invention relates to the field of down jackets, and more specifically to a down jacket with dynamic shoulder insulation based on inflatable airbags. Background Technology

[0002] Currently, down jackets have a significant weakness in shoulder insulation during winter outdoor activities. Because the shoulders are often used for carrying backpacks or engaging in vigorous movements, the down filling is easily compressed, leading to a thinner layer and reduced insulating air, causing rapid heat loss and creating "cold spots." While existing technologies, such as locally thickened filling or built-in electric heating elements, can improve shoulder insulation to some extent, these methods restrict freedom of movement, require external power, and pose inconvenience and safety hazards. Therefore, we propose a down jacket with dynamic shoulder insulation based on inflatable airbags. Summary of the Invention

[0003] The purpose of this invention is to provide a down jacket with dynamic shoulder insulation based on an inflatable airbag, which solves the technical problems of existing methods for improving shoulder insulation in down jackets, such as restricting the freedom of limb movement or relying on external power sources, which are inconvenient to use and pose safety hazards.

[0004] The present invention achieves the above objectives through the following technical solutions: A dynamic shoulder-warming down jacket based on inflatable airbags includes a down jacket body and a press-type self-priming inflation valve on the down jacket body. The inner side of the down jacket body is provided with a shoulder warming component corresponding to the wearer's shoulder. Each shoulder warming component is provided with an airbag component corresponding to both shoulders of the wearer. The air inlet of each airbag component is connected to the press-type self-priming inflation valve through a one-way pipe. The airbag component includes an airbag portion disposed on the shoulder warming component, and a plurality of dynamic heating components connected to the airbag portion and located within the shoulder warming component. The airbag portion is configured to expand after being filled with gas through a press-type self-priming inflation valve, thereby driving the dynamic heating components into a working state. In the working state, the dynamic heating components generate heat and transfer it to the wearer's shoulder when the wearer's shoulder moves.

[0005] A further improvement is that the shoulder insulation piece includes two sets of shoulder fitting pieces corresponding to the wearer's shoulders respectively, and a back fitting connecting piece for corresponding to the wearer's back is provided between the two sets of shoulder fitting pieces. Both the shoulder fitting pieces and the back fitting connecting piece are detachably connected to the inside of the down jacket body through connectors.

[0006] A further improvement is that the airbag component includes a main airbag disposed on the shoulder fitting piece, and the main airbag is provided with a number of auxiliary airbags on the side facing the shoulder fitting piece. The auxiliary airbags and the main airbag are interconnected through through holes, and the main airbag is connected to a press-type self-priming inflation valve through a one-way tube. The two sets of airbag components are interconnected by a pipe, and one of the airbag components is also connected to an exhaust pipe, the end of which is detachably covered with a pipe cap.

[0007] A further improvement is that the shoulder fitting piece has a cavity, and several sets of dynamic heating components are disposed in the cavity and correspond one-to-one with the auxiliary airbags. The dynamic heating component includes a heat insulation support component disposed in the cavity. One end of the heat insulation support component passes through the shoulder fitting piece and is connected to the main airbag. The heat insulation support component is movably sleeved on the outside of the auxiliary airbag. The bottom of the heat insulation support component is connected to the inner wall of the cavity through an annular contact friction plate. A heat insulation plate connected to the auxiliary airbag is movably disposed in the heat insulation support component. A friction element is disposed on the side of the heat insulation plate away from the auxiliary airbag. When the auxiliary airbag expands, the heat insulation plate moves toward the contact friction plate and contacts the inner wall of the contact friction plate.

[0008] A further improvement is that the friction element includes a bracket connected to a heat insulation plate, and the outer circumferential wall of the bracket is uniformly provided with a plurality of grooves along the circumferential direction. Each groove is rotatably provided with an eccentric friction ball for contacting the inner wall of the contact friction plate through a fixed shaft.

[0009] A further improvement is that friction particles are uniformly embedded in the inner wall of the contact friction pad.

[0010] A further improvement is that the cavity is filled with a down filling material.

[0011] A further improvement is that the side of the main airbag facing the inner side of the down jacket body is constructed to have multiple continuous arc-shaped cross sections extending in the vertical direction, the secondary airbag is semi-circular, and several sets of elastic connectors are provided between the upper and lower inner walls of the secondary airbag. The elastic connectors are used to assist the secondary airbag in driving the heat insulation plate to reset after the gas in the secondary airbag is discharged.

[0012] The beneficial effects of this invention are as follows: This invention features an airbag that can be inflated and controlled by the wearer, creating an adjustable-thickness air insulation layer on the shoulder to effectively prevent heat loss. As the airbag expands, it drives a dynamic heating element to activate, generating heat and transferring it to the shoulder during shoulder movement. This proactively compensates for the decrease in shoulder warmth caused by shoulder pressure and movement, achieving adaptive dynamic warmth without external power, high safety, and no restriction on limb movement. This improves the shoulder warmth and overall wearing comfort of the down jacket. Attached Figure Description

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1 Please see the appendix Figure 1-2 A dynamic shoulder-warming down jacket based on an inflatable airbag includes a down jacket body 1 (such as composed of an outer fabric, a thermal filling layer and an inner lining) and a press-type self-priming inflation valve 4 provided on the down jacket body 1. The press-type self-priming inflation valve 4 is a conventional component in the prior art, such as being widely used in press-type inflatable pillows in daily life, and will not be described in detail here. In this embodiment, the press-type self-priming inflation valve 4 is preferably installed in an internal pocket of the down jacket body 1 corresponding to the wearer's chest position or on a specially sewn valve seat. Airtightness is achieved through heat pressing or sewing processes. The choice of this position makes it easy for the wearer to touch and operate it by hand, and is not affected by external restraints such as backpack straps. The inner side of the down jacket body 1 is provided with a shoulder warming component 2 corresponding to the wearer's shoulders. In this embodiment, the surface contour of the shoulder warming component 2 conforms to the curvature of the human shoulder. Optionally, the shoulder warming component 2 in this embodiment adopts a composite structure of elastic spandex fabric wrapped with memory foam, but is not limited to this. Airbag components 3 are provided on both shoulders of the shoulder warming component 2. In this embodiment, the vertical cross-section of the airbag component 3 presents a curved structure that conforms to the natural curvature of the human shoulder, so that it can be inflated. It can be placed securely and comfortably on the wearer's shoulders like a custom-made curved air cushion. The air inlet of the airbag 3 is connected to the press-type self-priming inflation valve 4 through a one-way tube. Specifically, the one-way tube is a flexible one-way air guide tube, which is hidden inside the down jacket body 1. The user injects air into the airbag 3 by operating the press-type self-priming inflation valve 4. The airbag 3 then expands evenly, creating an adjustable-thickness, sealed air insulation layer between the shoulder and the down jacket body 1, effectively preventing heat loss. The airbag component 3 includes an airbag portion disposed on the shoulder warming component 2, and several sets of dynamic heating components connected to the airbag portion and located within the shoulder warming component 2. Optionally, the airbag portion in this embodiment can be made of thermoplastic polyurethane film. The airbag portion is configured to expand after being filled with gas through the press-type self-priming inflation valve 4, thereby driving the dynamic heating components into working state. When in working state, the dynamic heating components generate heat and transfer it to the wearer's shoulder when the wearer's shoulder moves (i.e., when the wearer's shoulder moves due to carrying or activity). This method only enters working state after the wearer actively inflates the air and generates heat as needed during actual movement. This solves the problem of the thermal insulation performance degradation of traditional static thermal insulation materials in the shoulder activity area due to long-term pressure and friction. By actively generating heat to compensate for heat loss in real time, it ensures continuous warmth and comfort in various scenarios from static to dynamic.

[0017] Example 2 Please see the appendix Figure 1-3Based on Embodiment 1, the shoulder warming component 2 of this embodiment includes two sets of shoulder fitting pieces 21 corresponding to the wearer's shoulders. Between the two sets of shoulder fitting pieces 21, there is a back fitting connecting piece 22 for the wearer's back. The two sets of shoulder fitting pieces 21 and the back fitting connecting piece together form a stable "vest"-shaped structure to enhance the overall wearing stability and fit. Both the shoulder fitting pieces 21 and the back fitting connecting piece 22 are detachably connected to the inside of the down jacket body 1 through connectors 23. In this embodiment, the connectors 23 can be a buckle structure in which the male snap button sewn on the warming component and the female snap button sewn on the inside of the down jacket body 1 cooperate with each other. Alternatively, they can be replaced with common detachable connection methods such as Velcro, magnetic buckles, or short-distance zippers. The detachable design of the shoulder insulation component 2 and the down jacket body 1 allows the shoulder insulation component 2 to more completely wrap the area where the shoulders and back meet, avoiding curling or displacement during activities due to single-point force. This ensures that the airbag component 3 and the dynamic heating component are always in the correct working position during shoulder movement, improving the reliability and comfort of long-term use. At the same time, it allows the wearer to flexibly install or remove the insulation component according to temperature, usage scenario or personal preference, and also facilitates the daily cleaning and maintenance of the down jacket body 1. It should be noted that the one-way pipe is also detachably connected to the airbag component 3, which does not affect the removal of the shoulder insulation component 2.

[0018] Please see the appendix Figure 3-4 As a preferred embodiment, the airbag component 3 includes a main airbag 31 disposed on the shoulder fitting piece 21. The main airbag 31 has several sets of auxiliary airbags 33 disposed on the side facing the shoulder fitting piece 21. The auxiliary airbags 33 and the main airbag 31 are interconnected through through holes. The main airbag 31 is connected to a press-type self-priming inflation valve 4 through a one-way pipeline. The two airbag components 3 are connected to each other by a cross-shoulder connecting pipe. One of the airbag components 3 is also connected to an exhaust pipe 37. The end of the exhaust pipe 37 is detachably equipped with a pipe cap (or integrated with a pressure relief valve, and a miniature pressure valve can also be installed inside the exhaust pipe 37). The pipe cap and the exhaust pipe 37 can be connected by threads.

[0019] When the wearer operates the inflation valve, air is injected into the main airbag 31 through the one-way tube and quickly inflates all the secondary airbags 33 through the internal through hole. The tubes connecting the shoulders ensure that the pressure of the shoulder airbags 3 is balanced in real time, and the exhaust pipe 37 is used to open the cap for quick active exhaust or pressure adjustment when needed.

[0020] Please see the appendix Figure 3-4Preferably, in this embodiment, the shoulder fitting piece 21 has a cavity 211, and several sets of dynamic heating components are disposed in the cavity 211 and correspond one-to-one with the auxiliary airbags 33. The dynamic heating component includes a heat-insulating support member 32 disposed in the cavity 211. The heat-insulating support member 32 is cylindrical, with one end penetrating through the shoulder fitting piece 21 and connected to the main airbag 31. The heat-insulating support member 32 is movably sleeved on the outside of the auxiliary airbag 33. The bottom of the heat-insulating support member 32 is connected to the inner wall of the cavity 211 through an annular contact friction piece 36. The heat-insulating support member 32 is provided with a heat-insulating plate connected to the auxiliary airbag 33. The heat-insulating plate and the auxiliary airbag 33 can be bonded with a flexible high-strength adhesive (such as silicone glue). The heat-insulating plate can move along its axial direction within the heat-insulating support member 32, thereby providing heat insulation. The heat insulation plate and heat insulation support 32 reduce heat transfer to the airbag component 3. The heat insulation plate is provided with a friction element on the side away from the auxiliary airbag 33. When the auxiliary airbag 33 expands, the heat insulation plate moves towards the contact friction plate 36 and contacts the inner wall of the contact friction plate 36. At this time, if the wearer's shoulder moves, the friction element and the contact friction plate 36 rub against each other, thereby continuously generating heat and directly transferring it to the wearer's shoulder. Optionally, the heat insulation support 32 in this embodiment can be made of glass fiber reinforced nylon injection molding or rigid silicone containing an aramid fiber skeleton. The heat insulation plate can be made of PTFE plate, etc. The contact friction plate 36 can be made of high wear-resistant nitrile rubber, or ceramic particle-rubber composite sheet (nitrile rubber or hydrogenated nitrile rubber as the matrix, filled with 30%-40% aluminum nitride or aluminum oxide powder, etc.).

[0021] Preferably, the friction component in this embodiment includes a bracket 34 connected to a heat insulation plate. The bracket 34 is cylindrical, and a plurality of grooves are evenly distributed along the circumferential direction on the outer circumferential wall of the bracket 34. Each groove contains an eccentric friction ball 35 (such as a solid sphere made of carbon fiber reinforced polyoxymethylene, to balance wear resistance and inertia) rotatably disposed therein via a fixed shaft for contacting the inner wall of the contact friction pad 36. The center of the eccentric friction ball 35 has a preset eccentric distance from the axis of the fixed shaft, so that when the entire friction component is pushed down by the heat insulation plate, the outer surface of each eccentric friction ball 35 can contact the inner wall of the contact friction pad 36. The inner wall of the friction pad 36 remains in contact. When the wearer's shoulder movement causes relative rotation or oscillation between the contact friction pad 36 and the bracket 34, due to the eccentric design between the eccentric friction ball 35 and the fixed axis, the friction force of the inner wall of the contact friction pad 36 on the eccentric friction ball 35 is converted into a torque that causes the eccentric friction ball 35 to rotate around the fixed axis, thereby causing the eccentric friction ball 35 to roll. Its surface rubs against the inner wall of the contact friction pad 36, thereby generating heat. This converts the low-frequency oscillation of the shoulder with limited amplitude and uncertain direction into the continuous rotational friction motion of the eccentric friction ball 35, improving the heat generation stability.

[0022] Preferably, friction particles are uniformly embedded in the inner wall of the contact friction plate 36 in this embodiment. For example, silicon carbide micro powder, alumina micro powder or diamond micro powder particles can be used. Part of their volume is embedded in the contact friction plate 36 matrix and part of them protrude to form a micro-rough surface, which increases the effective frictional resistance and contact area between the contact friction plate 36 and the eccentric friction ball 35, and improves the frictional heat generation effect.

[0023] Preferably, the cavity 211 in this embodiment is provided with a filling material 212, which is a loose down filling material. The frictional heat generated when the dynamic heating element is working is first absorbed by components such as the contact friction plate 36 with good thermal conductivity, and then conducted to the down filling material surrounding it. The down filling material retains the heat in the cavity 211 for a longer time and can continuously release warmth to the side of the down jacket body 1 that is close to the human skin.

[0024] Preferably, in this embodiment, the side of the main airbag 31 facing the inside of the down jacket body 1 is constructed to have multiple continuous arc-shaped cross sections extending in the vertical direction to fit the curve of the human shoulder. The secondary airbag 33 is semi-circular, and several sets of elastic connectors 23 (such as connecting strips or films made of highly elastic materials) are provided between the upper and lower inner walls of the secondary airbag 33. The elastic connectors 23 are used to assist the secondary airbag 33 in driving the heat insulation plate to reset after the gas in the secondary airbag 33 is discharged. The heat insulation plate resets so that the friction element separates from the contact friction plate 36. After the airbag 3 is deflated, it can actively and quickly reset to the initial separation state, avoiding residual contact and accidental wear of the friction structure during non-working periods.

[0025] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
