[0034] like Figures 1 to 3As shown, the present invention provides a self-heating down jacket, which includes a down jacket body 1, a heating plate 2 and a friction power generation device 3. The down jacket body 1 includes a lining 11, a down layer 12 and a fabric sewn in sequence from the inside to the outside; the heating plate 2 is arranged on the lining 11, and the heating plate 2 is used to heat the human body after being energized; the friction power generation device 3 includes a moving part 31 and a conductive part 32, the moving part 31 is arranged on the fabric, and the conductive part 32 is arranged on the down layer 12, and the conductive part 32 can be electrically connected to the heating plate 2; the movement of the fabric can drive the moving part 31 to move relative to the conductive part 32, so that the conductive part 32 generates current. In this embodiment, in order to clearly and concisely represent the structure and position of the heating plate 2 and the friction power generation device 3, the sleeve of the down jacket body 1 is not drawn; because the down jacket body 1 includes the down layer 12 sewn between the lining 11 and the fabric, it can effectively keep the human body warm and comfortable; because the lining 11 is provided with a There is a heating plate 2, which can emit heat to heat the human body after being energized. Therefore, when the user is in a severe cold environment, the heat of the heating plate 2 can be used to increase the body surface temperature and resist the cold, thereby greatly improving the environmental adaptability of the down jacket body 1; since the moving part 31 of the friction power generation device 3 is arranged on the fabric 11 and the conductive part 32 is arranged on the down layer 12, when the user is in an active state, the fabric can be moved by the swing of the body, and then the moving part 31 can be driven to move relative to the conductive part 32 to make the conductive part 31 generate current, so that the friction power generation device 3 generates electrical energy, and since the conductive part 32 is electrically connected to the heating plate 2, the friction power generation device 3 can utilize the kinetic energy of the human body's movement and convert part of the kinetic energy into electrical energy to supply power to the heating plate 2, thereby heating the human body; the self-heating down jacket can collect and utilize the kinetic energy of the human body to heat the human body without the need for additional power supply, saving energy, being green and environmentally friendly, and having good environmental adaptability and practicality.

[0035] Specifically, the heating sheet 2 is hot-pressed and packaged inside the lining 11 . The heating sheet 2 is a PTC flexible electric heating sheet commonly used in the art. When powered on, the temperature of the heating sheet rises, thereby being able to heat surrounding objects. The friction power generation device 3 is a friction electric nanogenerator, which can convert extremely small mechanical energy into electrical energy and output it to the outside through the friction electrification effect. The specific principle will not be elaborated here. In this embodiment, the moving part 31 and the conductive part 32 of the friction power generation device 3 are both flexible sheet or film structures, wherein the moving part 31 is made of PET polyester film and has good friction characteristics, and the conductive part 32 is made of graphene conductive material and has built-in interdigital electrodes. The moving part 31 is hot-pressed and packaged on the inside of the fabric, and the conductive part 32 is hot-pressed and packaged on the outside of the down layer 12, and the conductive part 32 is aligned with the moving part 31 along the thickness direction of the down jacket body 1. When the user is in an active state, as the body swings, the fabric of the down jacket body 1 at the corresponding position drives the moving part 31 to move relative to the conductive part 32, thereby causing the surfaces of the two to rub against each other and generate current in the interdigital electrodes of the conductive part 32. When the user is in a stationary state, the moving part 31 and the conductive part 32 remain relatively stationary, and no current is generated in the conductive part 32 at this time.

[0036] Specifically, if Figure 1 and Figure 2 As shown, a transmitting coil 33 is fixedly connected to the conductive member 32, and a receiving coil 21 is rotatably connected to the heating plate 2. The receiving coil 21 can be rotated to a heating position. At the heating position, the receiving coil 21 is directly opposite to the transmitting coil 33, and the receiving coil 21 can generate an induced current. The transmitting coil 33 is connected to the interdigitated electrodes in the conductive member 32, and the receiving coil 21 is connected to the heating resistor in the heating plate 2. When the user rotates the receiving coil 21 to the heating position, the receiving coil 21 and the transmitting coil 33 are directly opposite to each other along the thickness direction of the down jacket body 1. Based on the law of electromagnetic induction, when a changing current passes through the transmitting coil 33, an induced electromotive force is also generated in the receiving coil 21 and an induced current appears in the receiving coil 21, thereby energizing the heating plate 2. When the user needs to use the heating plate 2 to provide auxiliary heat, the receiving coil 21 is manually rotated to the heating position. When the user's temperature rises and the heating plate 2 is no longer needed to provide auxiliary heat, the receiving coil 21 is rotated away from the heating position. The structure is simple, and the user can adjust the state of the heating plate 2 at any time according to their own situation.

[0037] In order to improve safety during use, the receiving coil 21 is coated with silicone material to achieve the purpose of insulation.

[0038] Furthermore, if Figure 2As shown, the friction power generation device 3 also includes a battery 34, and the conductive member 32 is electrically connected to the transmitting coil 33 through the battery 34. The battery 34 can store the electric energy generated on the conductive member 32 and transmit it to the receiving coil 21 through the transmitting coil 33. Due to the provision of the battery 34, when the user is in a stationary state and needs the heating plate 2 to provide heat, the receiving coil 21 is manually rotated to the heating position. At this time, the electric energy stored in the battery 34 can continue to supply power to the heating plate 2 when the user is in a stationary state, thereby enriching the application scenarios of the self-heating down jacket and greatly facilitating daily use. A rectifier 35 is also provided between the conductive member 32 and the battery 34. The rectifier 35 is a diode rectifier bridge commonly used in the art. The rectifier 35 is connected to the interdigital electrodes of the conductive member 32, and can convert the alternating current in the interdigital electrodes into direct current and store it in the battery 34.

[0039] In order to improve the durability of the moving part 31 , a protective layer is coated on the outside of the moving part 31 to prevent the moving part 31 from being scratched and damaged by external foreign objects during use.

[0040] Furthermore, if Figure 2 As shown, the conductive element 32 is integrated with the rectifier 35 , the battery 34 and the transmitting coil 33 into an integral structure, and is uniformly hot-pressed and packaged on the outside of the down layer 12 .

[0041] Furthermore, if Figure 3 As shown, the down layer 12 includes a plurality of down bags 121, and the plurality of down bags 121 are evenly arranged along a first direction; the down bags 121 have a first end and a second end opposite to each other, the first end is fixedly connected to the lining 11, and the second end can swing around the first end, and the down bags 121 include a lining cloth and down filled in the lining cloth, and the lining cloth covers the down inside to form a plurality of independently arranged down bags 121; the first direction is the height direction of the down jacket body 1 from the hem to the neckline, and the plurality of down bags 121 are sequentially arranged on the lining 11 along the first direction to form a vertically arranged uniform structure; specifically, the first end of the down bags 121 is fixedly connected to the lining 11, and the second end can swing around the first end; ... One end is fixed to the lining 11 by hot pressing. Since the second end is a free end and can swing around the first end, the down bag 121 forms a loose-leaf structure that can be freely flipped. When the user is in a stationary state or the activity intensity is low, the down bag 121 is in a drooping state under the action of gravity. At this time, the multiple down bags 121 arranged evenly can effectively seal heat and maintain human body temperature; when the user is in an active state and reaches a certain activity intensity, the down bag 121 can be flipped and swung after being squeezed, thereby driving the air flow in the down jacket body 1, promoting perspiration and moisture removal, and thus improving the user's comfort.

[0042] Specifically, Figure 3As shown, the lining 11 is formed by splicing and sewing a breathable mesh 111 and an inner lining 112. The breathable mesh 111 is arranged opposite to the down bag 121, and the first end of the down bag 121 is hot-pressed on the inner lining 112. The down bag 121 is attached to the breathable mesh 111 under the action of gravity; the breathable mesh 111 has extremely strong air permeability. When the user is in a stationary state or the activity intensity is low, the down bag 121 is in a drooping state under the action of gravity. At this time, the down bag 121 is attached to the breathable mesh 111 and covers the breathable mesh 111 to prevent air flow from taking away the heat of the human body, which helps the user to keep warm; when the user is in an active state and reaches a certain activity intensity, the down bag 121 can be flipped and swung after being squeezed, and at this time the down bag 121 will break away from the contact with the breathable mesh 111, so that the water vapor formed by the evaporation of sweat can be quickly discharged through the breathable mesh 111.

[0043] The inner lining 112 is made of polyester fiber or dacron commonly used in the art. In order to further improve the air permeability of the lining 11 and ensure that the user can ventilate and dehumidify through the lining 11 when the user's activity intensity is relatively low, tiny air holes 1121 are laser-engraved on the inner lining 112.

[0044] Specifically, if Figure 3 As shown, the first end and the second end are arranged at both ends of the down bag 121 along the first direction. It can be understood that, along the direction from the hem of the down jacket body 1 to the neckline, multiple down bags 121 are arranged in sequence along the first direction, and the first direction is the height direction of the down jacket body 1 from the hem to the neckline, that is, the vertical direction when the user wears the self-heating down jacket; the end of the down bag 121 close to the neckline of the down jacket body 1 is the first end, and the end close to the hem of the down jacket body 1 is the second end, and the multiple down bags 121 are evenly arranged from top to bottom, and can droop under the action of gravity and stick to the breathable mesh 111.

[0045] Furthermore, if Figure 1 As shown, the friction power generation device 3 is arranged at the armpit position of the down jacket body 1. When the user walks and swings his arms normally, the moving part 31 of the friction power generation device 3 at the armpit position can be driven to move relative to the conductive part 32, thereby maximally utilizing the kinetic energy of human activity to generate electricity.

[0046] Furthermore, if Figure 1 As shown, the heating plate 2 is arranged at the back position of the down jacket body 1; specifically, two friction power generation devices 3 are arranged on the down jacket body 1, and the two friction power generation devices 3 are respectively arranged at the left and right armpit positions, and two heating plates 2 are also arranged, and the two heating plates 2 are respectively arranged on the left and right sides of the back position, and are respectively connected to the friction power generation devices 3 on the same side.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
