Description

Technical Field

[0001] This invention relates to the field of smart clothing and its temperature control methods, and in particular to a smart heating and cold-proof clothing and method that automatically achieves a thermal comfort balance for the human body. Background Technology

[0002] In the cold winter, people who travel or work outdoors face the challenge of not being able to control their outdoor environment. They often resort to wearing extra layers to ward off the cold. While this passive insulation method can improve warmth and reduce discomfort, it can also make people bulky and restrict movement. Furthermore, in extremely cold conditions, passive insulation alone may not be sufficient, potentially leading to frostbite, hypothermia, and other dangers. Therefore, the introduction of active heating is crucial. Active heating materials can not only prevent heat loss to some extent but also convert other forms of energy into heat, transmitting it to the body to generate a thermal effect. Thus, actively heated winter clothing is lighter, more convenient, and more effective than traditional winter clothing. Simultaneously, outdoor activities provide favorable conditions for the utilization of solar energy. Flexible thin-film solar cells can be closely integrated with the clothing, converting collected light energy into electrical energy to provide a continuous power supply for the heating materials inside the garment.

[0003] Furthermore, many existing heated winter clothing garments on the market still rely on manual selection of heating levels to determine the heating power output. Different heating levels correspond to a wide range of heating temperatures, and their heating effectiveness is often affected by the user's condition and the outdoor environment, meaning the heating effect may not meet expectations. Therefore, although some heated clothing can achieve precise temperature control of the heated areas, users often need to manually adjust the temperature multiple times, and when the user's activity level or outdoor environment changes, they need to readjust the temperature to achieve the desired comfortable heating temperature. Summary of the Invention

[0004] To address the shortcomings and defects of existing technologies, this invention provides clothing that automatically achieves a thermal comfort balance for the human body. The clothing includes a garment body, a power supply device, a heating device, an information acquisition device, an intelligent computing device, and a user interaction device, wherein:

[0005] The heating device includes several heating components, which are disposed in different areas of the garment body and are used to provide heating to the corresponding areas of the human body;

[0006] The information acquisition device includes one or more of the following: human skin temperature sensor and / or heart rate sensor, ambient temperature sensor, ambient humidity sensor, ambient wind speed sensor, ambient radiation temperature sensor, heating element temperature sensor, and clothing surface temperature sensor.

[0007] The user interaction device is used to interact with the user;

[0008] The information acquisition device and the user interaction device send the acquired information to the intelligent computing device. The intelligent computing device calls the intelligent thermal comfort balance algorithm based on the received information and calculates the heating power setting value of each heating component. The setting value is then sent to each heating component, and the heating component is controlled to work according to the setting value.

[0009] The power supply device is used to provide electrical energy to the heating device, the information acquisition device, and the intelligent computing device.

[0010] The intelligent thermal comfort balance algorithm specifically includes the following steps:

[0011] S1: The skin temperature t of the human body in a state of thermal comfort equilibrium. sk Set to the preset temperature value;

[0012] S2: The heart rate sensor detects the user's heart rate HR and calculates the corresponding metabolic rate M based on the HR;

[0013] S3: The user inputs visual data of the clothing they are wearing through a user interaction device, and the visual data description is converted into the clothing's thermal resistance I. cl1 I cl2 ; where I cl1 I cl2 These are the thermal resistance values ​​of the clothing on both sides of a certain electric heating component;

[0014] S4: Obtain the direct sunlight conditions at the location of the human body and convert them into correction parameter α;

[0015] S5: The ambient temperature sensor detects the ambient temperature ta;

[0017] S7: The ambient wind speed sensor detects the ambient wind speed v;

[0018] S8: The ambient radiation temperature sensor detects the average ambient radiation temperature.

[0019] S9: The heat flux density Q1 of the skin is calculated using the following formula:

[0020] Q1 = 58.15 M

[0021] S10: Calculate the heating temperature setpoint t of a certain heating element. h The calculation formula is:

[0022] t h =t sk -Q1·R1

[0023] in:

[0024] R1 = 0.155·I cl1

[0025] S11: Calculate the heating power of a certain heating element using the following formula:

[0026]

[0027] The formula for Q3 is:

[0028] Q3=(t h -t cl ) / R2

[0029] The formula for R2 is:

[0030] R² = 0.155·I cl2

[0031] Where: t cl The surface temperature of the garment is obtained by solving the following equilibrium equation:

[0032]

[0033] Among them: Q R and Q c These are the radiative heat transfer and convective heat transfer between the clothing surface and the external environment, respectively, and their calculation formulas are as follows:

[0034]

[0039] h c—The convective heat transfer coefficient between the outer surface of the clothing and the external environment;

[0040] h r h c The value is either the default value or a given value.

[0041] Furthermore, in step S11, the surface temperature t of the clothing is calculated. cl It is calculated using the bisection method, and the calculation error is controlled within 0.001.

[0042] Furthermore, during the heating start-up phase of a certain heating component, the heating power setting value W is increased by a certain percentage to compensate for the heat required for the garment to store heat during the start-up phase, ensuring that the user obtains sufficient heat and quickly reaches a stable and comfortable state.

[0043] Furthermore, step 2 involves using the heart rate-metabolic rate relationship curve to convert the user's heart rate measurement value HR into metabolic rate M and inputting it as a calculation parameter.

[0044] Furthermore, when a user uses the garment for the first time, the user's initial metabolic rate M is obtained through the user's activity status description and activity intensity-metabolic rate conversion table; using the correspondence between the initial heart rate measurement and metabolic rate, a targeted modified heart rate-metabolic rate relationship curve for the current user is obtained.

[0045] Furthermore, in step S3, the visualized clothing description is transformed into clothing thermal resistance I using a database of typical winter clothing thermal resistance values. cl And it is used as a calculation parameter input.

[0046] Furthermore, in step S4, the user inputs the direct sunlight conditions at the location of the human body through a user interaction device and converts it into a correction parameter α; or the user obtains the direct sunlight conditions through a corresponding sensor installed on the outside of the clothing and converts it into a correction parameter α.

[0047] Furthermore, the garment body is also equipped with a power management control module, which operates in the following manner:

[0048] When the output voltage of the flexible thin-film solar cell is greater than or equal to the working voltage of the flexible graphene heating element, the flexible thin-film solar cell is used as the sole power source.

[0049] When 0 < output voltage of flexible thin-film solar cell < working voltage of flexible graphene heating element, the direct power supply unit of lithium battery pack is used to supply power separately, and flexible thin-film solar cell charges the energy storage unit of lithium battery pack.

[0050] When the output voltage of the flexible thin-film solar cell is 0, the energy storage unit and the power supply unit of the lithium battery pack supply power simultaneously through electrical connection.

[0051] When the output voltage of the flexible thin-film solar cell is 0 and the charge of the lithium battery pack (including the energy storage unit and the direct power supply unit) is less than 20% of the total charge, an external power supply is required to charge the power supply module.

[0141] The following is combined Figures 3 to 5The structure of the garment in this embodiment is described below. The garment includes a garment body 1. The inner surface of the garment body 1 is designed with five fusion-type female-side bonding forms 3 for bonding five heating components. In a specific embodiment, the heating components are flexible graphene electric heating sheets 2. The inner surface of the garment body 1 is designed with one interlayer pocket for storing a power supply device. In a specific embodiment, the power supply device is a power box 7. The inner surface of the garment body 1 is also provided with a control button 6, which is connected to the power box 7 via an electrical wire 4. The back area of ​​the outer surface of the garment body 1 is provided with a flexible thin-film solar cell 11, which is attached to the garment body 1 via a snap fastener 10. It can be understood that the flexible thin-film solar cell 11 is also the power supply device for the intelligent heating garment. The flexible thin-film solar cell is an amorphous silicon polyimide flexible thin-film solar cell, which can receive solar energy during outdoor activities during the day. The flexible thin-film solar cell 11 is connected to the power box 7 via a one-way charging wire 8, which enters the inside of the garment through a dark hole 12 on the back of the garment body 1. The electrical energy converted by the flexible thin-film solar cell 11 is stored in the energy storage unit of the lithium battery pack in the power supply box 7 or directly powers the flexible graphene electric heating element 2. The output of the power supply box 7 powers the flexible graphene electric heating element 2 placed inside the garment via the wire 4. The flexible thin-film solar cell 11 can be flexibly removed or installed on the back of the garment body 1 via the snap fastener 10, and will not be obstructed by the hood of the garment body 1. The five flexible graphene electric heating elements 2 are freely installed and removed through five fusion-type female bonding forms 3 located between the front chest, front abdomen, and back waist of the garment body 1. The control button 6 can adjust the heating power of the flexible graphene electric heating elements 2. The power supply box 7 is placed in the inner pocket of the chest of the garment body 1.
