Description

Technical Field

[0001] This invention belongs to the field of down jacket technology, specifically relating to a down jacket with down filling based on human body thermogram partitioning. Background Technology

[0002] Traditional down jackets typically have a uniform filling density across all areas, designed to provide consistent warmth in a static environment. However, the rate of heat generation and loss varies significantly across different parts of the body, whether at rest or in motion. For example, areas like the neck, armpits, and sides of the torso lose heat quickly and are prone to feeling cold; while large muscle groups such as the chest, back, and upper arms generate more heat during exercise, and excessive warmth can lead to stuffiness and sweating. This indiscriminate approach to warmth fails to meet the body's dynamic thermal comfort needs, especially during outdoor activities, easily causing localized overheating and sweating or excessive cold and discomfort, affecting athletic performance and overall experience.

[0003] In existing technologies, some garments have attempted to improve breathability by incorporating breathable zippers or using different fabrics, but these are passive and rudimentary adjustments that cannot achieve precise, dynamic, and on-demand adjustment. Therefore, there is an urgent need for a down jacket that can dynamically adjust its warmth retention performance by specific zones. Summary of the Invention

[0004] The purpose of this invention is to provide a down jacket with down filling based on human body thermogram partitioning in order to solve the problems mentioned in the background art.

[0005] The present invention achieves the above objectives through the following technical solutions: A down jacket with down filling based on human body thermal mapping includes a dynamic adjustment module on the down jacket body and several adjustment components connected to the dynamic adjustment module and distributed on various parts of the down jacket body. The dynamic adjustment module is used to drive the adjustment components to change the thickness of the down layer in each part, so as to change the heat dissipation performance of different parts of the down jacket body.

[0006] Preferably, the dynamic adjustment module includes an air extraction component, which is connected to each adjustment component via a pipe; The adjusting components include a telescopic rod and limiting heads fixed at both ends of the telescopic rod, and the adjusting components are connected to each other through air pipes; The two limiting heads are fixedly connected to the lining and outer fabric of the down jacket, respectively. The telescopic rod changes the thickness of the down jacket body when it is shortened. The air extraction assembly is used to extract the gas from each adjusting component so that the length of the adjusting component changes.

[0007] Preferably, the air extraction assembly includes a housing, a cylinder fixedly disposed within the housing, a piston movably disposed within the cylinder, a rotating wheel rotatably mounted on the housing, a crank handle fixedly connected to the rotating wheel, and a crank connecting the rotating wheel and the piston. The cylinder includes an air inlet and an air outlet, and a one-way valve is provided at both the air inlet and the air outlet. When the piston reciprocates in the cylinder, gas enters the cylinder from the air inlet and is discharged from the air outlet. All adjusting components are connected to the air inlet of the cylinder. Both ends of the crank are rotatably connected to the piston and the wheel, and the rotation point of the crank and the wheel is at a non-center position of the wheel.

[0008] Preferably, an intermediate pipe is fixedly provided at the air inlet, and a through hole is provided in the middle section of the intermediate pipe to connect its inner cavity with the outside. A pin for changing the gas direction is provided at the through hole. When the pin is pulled out, the gas enters the air pipe and telescopic rod through the intermediate pipe. The telescopic rod is equipped with a first return spring for controlling the length of the telescopic rod.

[0009] Preferably, a second return spring is provided between the pin and the inner wall of the intermediate pipe for controlling the position of the pin relative to the intermediate pipe. The pin has a cavity, and one end of the pin is open in the middle pipe. The middle section of the pin has a window that connects to its cavity. After the window is moved out of the through hole, the gas enters the cavity of the pin through the window and then enters the inner cavity of the middle pipe through the opening.

[0010] Preferably, a heating element is movably installed inside the cavity of the pin, and a battery for supplying power to the heating element is provided on the housing.

[0011] Preferably, an air storage box is fixedly provided inside the housing. The air storage box has a No. 1 hole and a No. 2 hole that connect its inner cavity to the outside. The No. 1 hole is connected to the air outlet of the cylinder through an air pipe, and the No. 2 hole is connected to the inner cavity of the intermediate pipe through an air pipe. Among them, the gas pipe section between the No. 2 hole and the intermediate pipe is equipped with a valve to control the gas flow; The telescopic rod is provided with a No. 3 hole that connects its inner cavity to the outside. A limiting frame is fixedly installed at the No. 3 hole, a No. 3 return spring is fixedly installed on the limiting frame, and a tube plug for sealing the No. 3 hole is fixedly installed on the No. 3 return spring.

[0012] Preferably, a heating strip is movably installed inside the gas storage tank, and the heating strip is used to heat the gas inside the gas storage tank.

[0013] The beneficial effects of this invention are as follows: 1. This invention allows users to adjust the thickness of the down layer in specific areas by using adjustable components. Users can actively and in real time adjust the local warmth retention performance according to their own temperature sensitivity or activity intensity, greatly improving the adaptability of clothing in different activity scenarios.

[0014] 2. This invention cleverly integrates a mechanical adjustment system inside the garment, driven manually (by a crank) or electrically (by an electric pump), enabling active regulation of the garment's warmth retention performance. The added preheating and air-drying functions further enhance comfort after exercise and maintain the warmth retention of the down filling.

[0015] 3. This invention effectively solves the problem of overheating and sweating of the torso and back during exercise, while ensuring warmth in cold-prone areas such as joints, so that the wearer can keep their body surface dry and at a suitable temperature when exercising in cold environments, significantly improving athletic performance and comfort.

[0018] The present application will now be described in further detail. 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.

[0019] Example 1 like Figure 1-9 As shown, a down jacket with down filling based on human body thermal map partitioning includes a dynamic adjustment module disposed on the down jacket body 1, and a number of adjustment components 1 connected to the dynamic adjustment module and distributed on various parts of the down jacket body 1. The dynamic adjustment module is used to drive the adjustment components to change the thickness of the down layer in each part, so as to change the heat dissipation performance of different parts of the down jacket body 1.

[0020] The dynamic adjustment module includes an air extraction component, which is connected to each adjustment component via a pipe. The air extraction component is used to remove fluid from each adjustment component to change the length of the adjustment component.

[0021] It's important to note that while traditional down jackets have a uniform filling density across all areas, the rate at which heat is generated and lost varies in different parts of the body, whether at rest or during movement. The neck, armpits, sides of the torso, and joints lose heat quickly and are more prone to feeling cold. The chest, back, upper arms, and thigh muscles generate a lot of heat during exercise, and excessive warmth can lead to stuffiness and sweating. The extremities require extra warmth.

[0022] In this embodiment, the down jacket body 1 is first statically divided into sections. The shoulders, back of the neck, and sides of the core torso are designed with high loft and high down fill. The armpits, middle back, and chest are designed with lower down fill and are combined with breathable fabrics or spliced ​​elastic breathable materials to facilitate heat dissipation and moisture wicking. The basic insulation area and other parts maintain the standard fill amount.

[0023] Based on this, this embodiment adds a dynamic adjustment module. When the human body is engaged in strenuous exercise, the dynamic adjustment module can make targeted adjustments to each adjustment component. According to the extension and contraction range of each adjustment component, each adjustment component will shorten to different degrees. When the adjustment component shortens, it can change the thickness of different parts of the down jacket body 1. Compressing the down reduces the warmth of the down, which is conducive to the rapid heat dissipation of high heat-generating parts, thereby dynamically adjusting the local warmth.

[0024] Preferably, the air extraction assembly in this embodiment includes a housing 2, a cylinder 3 fixedly disposed within the housing 2, a piston 4 movably disposed within the cylinder 3, a rotating wheel 5 rotatably mounted on the housing 2, a crank handle 6 fixedly connected to the rotating wheel 5, and a crank 7 connecting the rotating wheel 5 and the piston 4. The housing 2 can be sewn or glued to the down jacket body 1 for easy operation. Its position can be chosen at the chest of the body, which not only does not affect movement but also facilitates operation.

[0025] The cylinder 3 includes an air inlet 8 and an air outlet 9. Both the air inlet 8 and the air outlet 9 are equipped with one-way valves. When the piston 4 reciprocates in the cylinder 3, gas enters the cylinder 3 through the air inlet 8 and is discharged through the air outlet 9.

[0026] Both ends of the crank 7 are rotatably connected to the piston 4 and the wheel 5, and the rotation point of the crank 7 and the wheel 5 is at a non-center position of the wheel 5.

[0027] The working principle of the air extraction assembly is as follows: manually turning the crank handle 6 drives the rotating wheel 5 to rotate, and the rotating wheel 5 drives the crank 7 and piston 4 to move. Since the crank 7 is installed at a non-center position of the rotating wheel 5, when the rotating wheel 5 rotates, the crank 7 drives the piston 4 to move back and forth in the cylinder 3.

[0028] When piston 4 moves away from the air inlet 8 of cylinder 3, it performs a suction action, drawing gas into cylinder 3 from the pipes and adjusting components, preventing air from entering through the one-way valve at the outlet 9. When piston 4 moves closer to the air inlet 8 of cylinder 3, it compresses the gas inside cylinder 3. Due to the one-way valve, the gas can no longer enter the adjusting components and the pipes connecting them, and the gas can only be discharged from the outlet 9.

[0029] The continuous reciprocating motion can continuously extract gas from the regulating components, causing each regulating component to shorten continuously until it is adjusted to the set minimum length.

[0030] Preferably, a micro electric pump and solenoid valve are used to control the expansion and contraction of the regulating components to change the thickness and air layer of the clothing, resulting in a faster response, greater controllability, and the use of a detachable power bank for energy.

[0031] In this embodiment, the adjusting components include a telescopic rod 10 and limiting heads 11 fixed at both ends of the telescopic rod 10. The adjusting components are interconnected through air pipes, and all adjusting components are connected to the air inlet 8 of the cylinder body 3. The telescopic rod 10 can be a multi-section telescopic rod 10, with a large extension range.

[0032] The two limiting heads 11 are fixedly connected to the inner and outer fabrics of the down jacket body 1, respectively, and the telescopic rod 10 changes the thickness of the down jacket body 1 when it is shortened.

[0033] To facilitate the re-intake of air into the telescopic component, an intermediate pipe 12 is fixedly installed at the air inlet 8. The middle section of the intermediate pipe 12 has a through hole 14 connecting its inner cavity to the outside. A pin 13 for changing the direction of gas is movably installed at the through hole 14. When the pin 13 is pulled out, the gas enters the air pipe and telescopic rod 10 through the intermediate pipe 12.

[0034] To ensure the telescopic rod 10 can extend normally, a first return spring 15 is provided inside the telescopic rod 10 to control its length. When the telescopic rod 10 shortens, the first return spring 15 is compressed. When gas enters the telescopic rod 10, the first return spring 15 causes the telescopic rod 10 to extend rapidly, causing the two limit heads 11 to separate the lining and outer fabric of the down jacket body 1, thereby allowing the down to unfold, restoring its loft, and increasing its warmth retention.

[0035] To facilitate the use of the pin 13, a second return spring 16 is provided between the pin 13 and the inner wall of the intermediate pipe 12 to control the position of the pin 13 relative to the intermediate pipe 12.

[0036] The pin 13 has a cavity 17. One end of the pin 13 is open at the middle pipe 12. The middle section of the pin 13 is provided with a window 18 that connects to its cavity 17. After the window 18 is moved out of the through hole 14, the gas enters the cavity 17 of the pin 13 through the window 18, and then enters the inner cavity of the middle pipe 12 through the opening.

[0037] In use, manually pull out the pin 13 to stretch the second return spring 16. After the gas enters, release the pin 13. The second return spring 16 will drive the pin 13 to reset, thus completing the sealing of the through hole 14.

[0038] The second return spring 16 also prevents the pin 13 from being lost, ensuring the normal use of the air intake function.

[0039] Example 2 Unlike Embodiment 1, a heating strip 19 is movably installed in the cavity 17 of the pin 13, and a battery for supplying power to the heating strip 19 is provided on the housing 2.

[0040] It should be noted that the electrical energy provided by the battery enables the heating strip 19 to generate heat, which raises the temperature of the heating strip 19 and the pin 13. During air intake, the gas is appropriately heated, so that the gas entering the telescopic rod 10 has a certain temperature rather than being cold air.

[0041] The warm air entering the telescopic rod 10 is dissipated outward through thermal radiation, causing the temperature of the down to rise. The thermal radiation from the telescopic rod 10 can help keep the human body warm, thereby reducing the feeling of coldness after sweating during exercise and lowering the chance of catching a cold.

[0042] Example 3 Unlike embodiment 2, an air storage box 20 is fixedly provided inside the housing 2. The air storage box 20 has a first hole 2114 and a second hole 22 that connect its inner cavity to the outside. The first hole 2114 is connected to the air outlet 9 of the cylinder 3 through an air pipe, and the second hole 22 is connected to the inner cavity of the intermediate pipe 12 through an air pipe.

[0043] Among them, the gas pipe section between the second hole 22 and the intermediate pipe 12 is equipped with a valve 23 to control the gas flow.

[0044] The telescopic rod 10 is provided with a No. 3 hole 24 that connects its inner cavity to the outside. A limit frame is fixedly provided at the No. 3 hole 24. A No. 3 return spring 25 is fixedly provided on the limit frame. A tube plug 26 for sealing the No. 3 hole 24 is fixedly provided on the No. 3 return spring 25.

[0045] It should be noted that after being compressed and then unfolded, the down is difficult to return to its initial loft, thus affecting the warmth retention performance of the down jacket body 1. In this embodiment, an air storage box 20 is added. The gas discharged from the air outlet 9 of the cylinder 3 enters the air storage box 20 through the air pipe and is stored, increasing the air pressure inside the air storage box 20. After the telescopic rod 10 extends, the valve 23 is opened, and the gas in the air storage box 20 enters the intermediate pipe 12 under pressure and moves to the telescopic rod 10 through the pipe. Because the air pressure inside the air storage box 20 is greater than the air pressure inside the telescopic rod 10, the increased air pressure causes the pipe plug 26 at the third hole 24 to be pushed out of the third hole 24, and the gas inside the telescopic rod 10 is ejected outward from the third hole 24.

[0046] The gas ejected from hole 24 slowly moves inside the down jacket body 1, blowing the down and thus opening up the down sections of the down jacket body 1 and moving the down within the down sections, allowing the down to return to its initial loft.

[0047] In addition, the gas ejected from the telescopic rod 10 is dry gas, which can remove the moisture generated during movement adsorbed on the down, making the down drier and effectively improving the down's warmth retention performance.

[0048] Preferably, a heating strip is movably installed inside the air storage box 20. The heating strip heats the gas inside the air storage box 20, so that the gas ejected from the No. 3 hole 24 has a certain temperature, which helps to improve the drying effect of down and can also provide appropriate insulation when the human body feels cold.

[0049] 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.
