[0058] Embodiment 1

[0059] The present utility model provides a detachable assembly type multi-region intelligent independent temperature control heating clothing, which comprises a heating clothing body 1, a heating assembly 2, a controller assembly 3 and an intelligent temperature control power supply assembly 4. Different from the prior art, in the present application, the controller and the heating module are separated and designed in a detachable manner, which will be described in detail below with reference to the block diagram shown in the figure. Figure 2 As shown in the figure, the present application mainly includes the following parts:

[0060] As shown in the figure, the present application mainly includes the following parts: Figure 2 The composition of the intelligent temperature control power supply assembly 4 includes:

[0061] The composition of the intelligent temperature control power supply assembly 4 includes:

[0062] 4a: Lithium battery pack, providing power to the entire system. 4b: Power control unit, used to regulate the power output to the heating element, specifically through technologies such as PWM (Pulse Width Modulation). 4c: Power management MCU, used to monitor the status of the lithium battery pack 4a and control the output of the power control unit 4b, and communicate with the controller component 3 to control the heating power according to a preset control algorithm, thereby achieving temperature regulation.

[0063] The controller component 3 consists of:

[0064] 3a: Controller MCU, responsible for communicating with the intelligent temperature control power supply component 4, receiving user operation commands (such as button presses, remote control signals, etc.), and communicating with the power management MCU in real time as the main controller. 3b: Button unit and light display unit, used to provide a user interface and display the current operating status.

[0065] The heating component 2 comprises:

[0066] 2a: First heating element, including such as Figure 6 As shown in 201, a built-in NTC thermistor is used to sense the temperature of the heating element. 2b: Second heating element, including as... Figures 6-7 As shown in 202-213, multiple second heating elements are connected in parallel, and can be added or removed as needed.

[0067] In the above description, the intelligent temperature control power supply component 4 is connected to the controller component 3 via the positive and negative power supply terminals and a signal line, and is also connected to the heating component 2 via the positive and negative power supply terminals. The controller component 3 communicates with the power management MCU (4c) of the intelligent temperature control power supply component 4 via the signal line to obtain the status and temperature information of the lithium battery pack (4a) and send control commands.

[0068] The working principle of the intelligent temperature-controlled power supply component is as follows:

[0069] The intelligent temperature control power supply component communicates with the controller component via a signal line. Once communication is normal, the intelligent temperature control power supply component outputs voltage through the positive and negative terminals of the power supply to power the controller component and the heating component.

[0070] The NTC thermistor built into the first heating element is connected between the signal pin and the negative power supply. The resistance of the NTC thermistor changes with temperature. The power management MCU can calculate the resistance of the NTC thermistor by detecting the voltage change on the signal pin, and thus obtain the temperature of the first heating element.

[0071] The power management MCU controls the heating power of the heating component by adjusting the duty cycle of the PWM signal of the power control unit based on the temperature of the first heating element, thereby achieving closed-loop temperature control.

[0072] The working principle of the controller assembly is as follows:

[0073] The controller assembly is powered by the lithium battery pack through the positive and negative power supply terminals. When the user switches the gear through the key unit, the controller MCU sends the corresponding control instruction to the power management MCU through the signal line. The power management MCU adjusts the output of the power control unit according to the received control instruction, thereby changing the heating power of the heating assembly.

[0074] The working principle of the heating assembly is as follows:

[0075] The heating assembly includes a plurality of groups of heating fins, which are composed of first heating fins and other parallel second heating fins. The first heating fins are internally provided with NTC thermistors for temperature detection and cannot be disassembled and are fixed at a specific position of the heating garment, such as the neck. The other second heating fins can be disassembled and combined according to the user's needs.

[0076] All the heating fins are connected in parallel to ensure that the increase or decrease of a single heating fin will not affect the normal work of other heating fins.

[0077] According to the formula P = U2 / R (where P is power, U is voltage, and R is resistance), the heating power of a single heating fin can be adjusted by adjusting the resistance value of different heating fins to meet the user's demand for different heating powers.

[0078] In this embodiment, the single bus communication mode is adopted between the intelligent temperature control power supply assembly and the controller assembly, and the bidirectional transmission of data is realized through a signal line.

[0079] In order to facilitate the user's use, the intelligent temperature control power supply assembly can also be compatible with old devices that do not support communication functions.

[0080] As Figure 3 indicated, a typical circuit connection diagram of the intelligent temperature control power supply assembly and the controller assembly is provided. The description of this circuit is as follows:

[0081] The intelligent temperature control power supply assembly is connected to the controller assembly through the positive and negative power supply terminals and the signal line, and is connected to the first heating fin through the positive and negative power supply terminals.

[0082] When the intelligent temperature control power supply assembly detects that the signal pin is high, it is judged that no device is inserted, at which time the power management MCU controls the internal power supply module to close the output, and there is no voltage output at the positive and negative power supply terminals.

[0083] When the intelligent temperature control power supply assembly is connected to an old device (a module without disassembly function), the old device is connected through the DC interface. The DC interface of the old device can be two-stage or three-stage, as shown in Figure 4 .

[0084] Two-stage DC interface: 1 pin (41) and 2 pin (42) are a whole, connecting the negative pole of the power supply; 3 pin (43) connects the positive pole of the power supply. Three-stage DC interface: 1 pin (41) is the negative pole of the power supply, 2 pin (42) is the signal pin, and 3 pin (43) is the positive pole of the power supply. Since the old device does not have a communication pin, in the two-stage DC interface, the communication pin connected to the corresponding interface is always connected to the negative pole of the power supply.

[0085] When the device supporting the detachable function is accessed, the smart temperature control power supply component detects that the signal pin is at low level, and turns on the power supply module in the power management MCU.

[0086] The heating fin NTC is used to detect the temperature of the heating fin and feed back the temperature signal to the controller component.

[0087] The controller MCU (for example, Q5 in Figure 3 According to the feedback of the NTC thermistor in the heating component 2 and the user's settings, the controller MCU controls the conduction and turn-off of the power tube, thereby adjusting the heating power of the heating fin.

[0088] In addition, Figure 3 It should be noted that:

[0089] (1) SW1 is a key switch, which can pull the signal pin low when pressed, and is used to wake up the smart temperature control power supply component or control gear switching.

[0090] (2) R29 has a resistance value much larger than that of R30, for example, R29 can be 100kΩ and R30 can be 5kΩ, which is used to pull the signal pin to high level when the key is opened, and short-circuit R29 when the key is closed, and the signal pin is grounded through R30.

[0091] (3) C1 is used for insertion wake-up. When inserted for the first time, the signal pin is charged through R27 to the capacitor C1, which pulls down the signal pin for a period of time, realizing the wake-up of the smart temperature control power supply component output voltage.

[0092] In combination with Figure 2 , Figure 3 and Figure 5 , the communication and control process of the smart temperature control power supply component 4 and the controller component 3 includes:

[0093] Power-on initialization: after the controller component 3 is powered on, the controller MCU (3a) completes the initialization and pulls down the signal pin, establishing a communication connection with the smart temperature control power supply component 4.

[0094] Power supply: the power management MCU (4c) of the intelligent temperature control power supply component 4 determines whether the device is connected by monitoring the level on the signal pin. When a low level is detected, the power management MCU (4c) starts the internal power supply module and power control unit (4b) to start external power supply.

[0095] Communication: when communication is needed, the controller MCU (3a) initiates a communication request. After receiving the communication request, the power management MCU (4c) performs the corresponding operation according to the specific instructions.

[0096] Gear adjustment: when the user switches the gear through the key unit (3b), the controller MCU (3a) sends the corresponding gear adjustment instruction to the power management MCU (4c) through the signal line. The power management MCU (4c) adjusts the duty cycle of the PWM signal output by the power control unit (4b) according to the received instruction, thereby changing the heating power of the heating component 2.

[0097] Further, when the heating component 2 reaches the set temperature, the duty cycle will decrease or the power module will be closed, at this time the battery has no output, the controller component 3 is powered by the internal capacitor C3, when the voltage decreases to a certain voltage, the controller MCU (3a) sends a controller command, and the intelligent temperature control power supply component 4 provides a keep-alive pulse.

[0098] The above embodiment describes the basic functions of the controller component 3, and according to the actual application requirements, the functions of the controller component 3 can also be extended. For example, a Bluetooth module can be added to realize mobile phone APP control; a remote control receiving module can be added to realize remote control; a vibration motor can be added to provide a vibration reminder function. As long as the basic communication protocol and control logic are met, users can choose different controller modules according to their own needs to realize more rich control functions and improve user experience.

[0136] In order to more flexibly adjust the heating area, a plurality of sub-clasps 25 can be arranged on the heating assembly 2, and a plurality of corresponding female clasps 251 can be arranged on the heating garment body 1. Users can select different sub-clasps 25 and female clasps 251 for connection according to needs, so as to adjust the position and number of the heating sheet, such as Figure 12Fig. 1 shows a schematic diagram of a heating assembly 2 with two adjustable heating areas, as shown in (a) and (b).

[0137] Figure 12 Fig. 1 shows a schematic diagram of a heating assembly 2 with two adjustable heating areas, as shown in (a) and (b).

[0138] In order to enhance the connection between the heating assembly 2 and the heating garment body 1, especially in the case of using multiple sub-male buckles, some auxiliary connection methods can be used, such as magic tape, binding tape, and other non-electric connection devices.

[0139] As a further embodiment:

[0140] The controller 31 is also designed to be replaceable. The three-segment DC interface schematic diagram is shown in Fig. 3. Figure 4 As shown in Fig. 3, 1 pin (41) is the negative electrode for connecting the negative electrode of the power supply, 2 pin (42) is the signal pin for transmitting the control signal, and 3 pin (43) is the positive electrode for connecting the positive electrode of the power supply. Through the three-segment DC interface, the power supply of the power line and the control function of the signal line can be realized.

[0141] Referring to Fig. 4, Figure 13 As shown in Fig. 4, another connection schematic diagram of the controller assembly 3 on the heating garment body 1 is provided, and in the figure:

[0143] 3-2 is a controller connected with the connection base 3-1 through a knob or a buckle. The connection base 3-1 and the controller 3-2 are integrated with contacts inside. When the controller 3-2 is connected to the connection base 3-1 through the knob or the buckle, the contacts are conductive, realizing power supply and signal transmission.

[0144] Among them, the connection base 3-1 can be arranged at multiple positions of the heating garment, such as the left chest, the right chest, etc. The user can install the controller 3-2 on any one of the connection bases 3-1, realizing the position replacement of the controller 3-2. When a connection base 3-1 is not installed with a controller 3-2, a decorative cover plate or badge, etc. can be installed, playing a role in aesthetics.

[0145] Embodiment 4

[0146] In practical applications, users may need to control the temperature of different heating pads independently. For example, the temperature of the back heating pad may need to be set higher than that of the pocket heating pad. In order to meet this requirement, independent temperature control of each heating pad needs to be achieved.

[0147] In order to achieve more intelligent and complex control, a simple control chip can be built into the heating assembly. The control chip can adjust the heating power of the heating pad according to the preset control algorithm and user settings, achieving precise temperature control. The following will be explained in detail in combination with Figure 14 and examples:

[0148] As shown in Figure 14 , compared with Figure 2 , the main difference of the embodiment is that a control module is built into each heating assembly 2 for independent control and intelligent control of each heating pad.

[0149] Among them, the power module is similar to Figure 2 the intelligent temperature control power supply assembly 4, which provides power for the entire system.

[0150] The control module is similar to Figure 2 the controller assembly 3, which can be implemented by an MCU with built-in Bluetooth or WIFI wireless communication module, used to control the instructions of the power module, and adjust the heating power of the heating pad according to the preset control algorithm and feedback of the temperature sensor, to achieve precise temperature control.

[0151] The heating module is similar to Figure 2 the heating assembly 2, which contains heating pads and control modules (see below Figure 15 ), and each heating module can be controlled independently.

[0152] In this structure, the control module receives instructions to control the power module, collects feedback signals from the temperature sensor, adjusts the heating power of the heating pad according to the preset control algorithm, and can communicate with the control modules of other heating modules (see below Figure 15 ) to achieve collaborative work.

[0153] Figure 15 The principle diagram of the internal control module of the heating module, mainly including the following parts:

[0154] (1) Power supply module: power supply for other parts of the control module;

[0155] (2) MCU: the core of the control module, responsible for receiving control instructions, collecting sensor data, executing control algorithms, etc.

[0156] (3) ID identification module: through the identification of the level of the ID pin or ID signal, the ID of the heat generating component is determined;

[0157] (4) Onboard NTC: used for detecting the temperature of the environment where the control module is located or the temperature of the PCB;

[0158] (5) Heat sheet NTC: used for detecting the temperature of the heat sheet;

[0159] (6) Power control module: adjusts the heating power of the heating wire according to the control signal of the MCU;

[0160] (7) Heating wire: a component that generates heat.

[0161] In order to realize the independent control and management of each heat generating component 2, each heat generating component 2 needs to have a unique ID. The control module can obtain the ID of the heat generating component 2 through the ID pin of the ID identification module. For example, a plurality of ID identification pins can be provided on the heating clothing body 1, and the level or signal of each ID identification pin corresponds to a unique ID. When the heat generating component 2 is connected to the heating clothing body 1, the control module can obtain the ID of the heat generating component by detecting the level or signal of the ID identification pin.

[0162] As Figure 16 is the schematic diagram of the ID identification circuit, which mainly includes the following parts:

[0163] (1) Clothing part:

[0164] VCC: positive electrode of power supply;

[0165] R_ID1: ID identification resistance, each ID identification pin corresponds to a different resistance value;

[0166] ID interface: used for connecting the ID pin of the heat generating component.

[0167] (2) Heat sheet part:

[0168] R34, R35, R33: internal resistance of the heat sheet;

[0169] VCC_ADC: connected to the ADC (analog-to-digital converter) input pin of the control module, used for detecting voltage;

[0170] ID_ADC: connected to the ADC input pin of the control module, used for detecting voltage.

[0171] In the circuit, the resistance value of R_ID1 of each ID interface of the clothing part is different. For example, the R_ID1 corresponding to ID interface 1 is 1kΩ, the R_ID1 corresponding to ID interface 2 is 2kΩ, and so on. The resistance values of the heating sheet part, resistors R33, R34 and R35 are the same.

[0172] When the heating component 2 is connected to the corresponding ID interface of the clothing, different R_ID1 will generate different voltage values through the resistance voltage division principle. The control module detects the voltage value of the ID_ADC pin through the ADC, and determines the ID of the heating component according to the preset voltage value and the corresponding relationship of the ID. The heating sheet ADC value is used for judgment, which is simple and does not need to increase additional communication pins.

[0173] As a further embodiment:

[0174] Reference Figure 17 The improved internal control module of the heating module is shown in the principle block diagram. Compared with Figure 15 , the embodiment mainly adds the following parts:

[0175] 116c: Bridge rectifier circuit, used for commutation of input DC voltage, to ensure that no matter the power supply is connected in positive or negative, the correct power supply voltage can be provided for the control module;

[0176] 116d: Bidirectional power control module, used for controlling the heating power of the heating wire, and capable of realizing bidirectional current control, that is, no matter the power supply is connected in positive or negative, the heating power of the heating wire can be normally controlled;

[0177] 116a: Power interface, used for connecting the power supply;

[0178] 116b: LDO voltage stabilizer, used for stabilizing the voltage to a suitable level;

[0179] 116f: Power control module, used for controlling the power of the heating wire;

[0180] 116g: Heating wire, a heating component.

[0181] The functions of MCU, ID recognition, on-board NTC, heating sheet NTC and ID recognition module are the same as those in Figure 15 .

[0182] The advantages of adding the bridge rectifier circuit (116c) and the bidirectional power control module (116d) are:

[0183] 1) Simplify production: no need to distinguish the positive and negative poles of the power supply interface, and simplify the production process.

[0184] 2) Convenient for users: users do not need to worry about the problem of reverse connection of power supply, and the convenience of use is improved.

[0185] 3) Prevent damage: avoid circuit damage caused by reverse connection of power supply, improve system reliability.

[0186] Similarly, using a simple H-bridge or multiple MOS can achieve positive and negative connection control of the heating wire, which will not be repeated here.

[0187] On this basis, in order to simplify the connection and facilitate user operation, the utility model discloses a novel child-mother buckle as shown in Figure 18 The power supply, signal and ID recognition function are integrated in one connector, which specifically comprises:

[0188] In Figure 18 :

[0189] 1. Child buckle shell: the external protective shell of the child buckle. 2. Child buckle outer ring: the external conductive ring of the child buckle, used for connecting the power supply. 3. Child buckle inner ring: the internal conductive ring of the child buckle, used for ID recognition or signal communication. 4. Mother buckle shell: the external protective shell of the mother buckle. 5. Mother buckle outer ring: the external conductive ring of the mother buckle, used for connecting with the child buckle outer ring (2) to transmit power. 6. Insulating layer: used for isolating the mother buckle outer ring (5) and the mother buckle inner ring (8) to prevent short circuit. 8. Mother buckle inner ring: the internal conductive ring of the mother buckle, used for connecting with the child buckle inner ring (3) to transmit ID recognition or signal.

[0190] The advantages of the above structure are as follows: integrated design: the power supply, signal and ID recognition function are integrated in one connector, reducing the number of interfaces and simplifying the connection. Convenient operation: users only need to align the child buckle and the mother buckle for connection, which is simple and convenient. Aesthetically pleasing: reducing the number of wire harnesses makes the heating apparel more aesthetically pleasing.

[0191] In specific application, it is divided into positive child-mother buckle and negative child-mother buckle, and the conductive ring (3 or 8) inside the positive child-mother buckle integrates an ID recognition resistor mentioned earlier, which is used for identification at positions similar to Figure 6 , Figure 6 The fixed position corresponds to a fixed ID resistor. The conductive ring (3 or 8) inside the negative mother buckle is used for signal pin communication, directly connecting the signal pin.

[0192] Further explanation, the ID recognition function can be used in the following scenarios:

[0193] (1) Real-time display of the number and position of the currently connected heating components on the mobile phone APP.

[0194] (2) User hot plug or replace the heating component after power off, the system can automatically identify the position and ID of the new heating component.

[0195] (3) Realize more complex control strategy, for example, set different temperature target according to different position of heat generating component.

[0196] As a further elaborated embodiment:

[0197] Compound a piece of PCB board on the heat generating module, the PCB board can adopt FPC (flexible circuit board) or ordinary hard PCB board, and integrate some simple circuit components on it, for example, power control circuit, ID identification circuit, etc., so as to realize more complex functions, such as Figure 19 As shown in the figure.

[0198] In Figure 19 , the application further discloses a heat generating component and a heating garment.

[0199] 1. The sub buckle on the heat generating component; 2. The connecting wire; 3. The flexible FPC or PCB board; 4. The PCB board load part; 5. The power supply negative pole connecting wire; 6. The heating sheet bottom cloth; 7. The female buckle on the heating garment body; 8. The connecting wire on the heating garment body; 9. The heating sheet NTC; 10. The rivet fixed connection; 11. The heating wire.

[0200] Wherein, the heat generating component is connected with the female buckle on the heating garment body through the sub buckle (1). The female buckle on the clothes is provided with an ID identification pin, which is connected with the power supply positive pole through an ID resistor, and is used for heat generating component identification on the garment.

[0201] In the communication mode, the controller module and the heat generating component can be communicated through the inner circle signal pin of the sub and female buckles.

[0202] Embodiment 5

[0203] In order to realize the complex temperature control function, the application adopts the following software control logic:

[0204] 1) The software flow chart of the main controller (controller MCU) is shown in the figure, and specifically includes: Figure 20

[0205] S1 System power on: the main controller and all heat generating components are powered on.

[0206] S2 Initialization: the main controller is initialized, including loading the preset ID list.

[0207] S3 Polling device: the main controller queries the online device (heat generating component) one by one according to the preset ID list.

[0208] S4 Send query command: the main controller sends a query command to the current queried device.

[0209] ​S5 Wait for response: The master controller waits for the response of the device.

[0210] S6 Device offline: If no response from the device is received within the preset time, the device is marked as offline.

[0211] S7 Receive response: If the response from the device is received, read the temperature, power, status, etc. information of the device.

[0212] S8 Send control command: The master controller sends control commands to the device according to the user's settings and preset control algorithm, such as setting the target temperature, adjusting the heating power, etc.

[0213] S9 Loop: The master controller continues to query the next device and repeats steps S4-S8 until all devices are queried.

[0214] S10 Timed polling: The system performs a timed loop and re-polls all devices, including offline ones, to ensure real-time device status.

[0215] 2) From the controller software flowchart, the flow description is as shown in Figure 21 , which specifically includes:

[0216] Step 1, power-on initialization: the slave controller is initialized after power-on.

[0217] Step 2, read ID: the slave controller reads its own ID information.

[0218] Step 3, compare ID: compare the read ID with the internally stored ID.

[0219] Step 4, update ID: if the IDs are inconsistent, update the internally stored ID and write the new ID to the EEPROM or other non-volatile memory.

[0220] Step 5, wait for instructions: the slave controller waits to receive instructions from the master controller.

[0221] Step 6, receive instructions and parse: after the slave controller receives the instructions, parse the type and content of the instructions.

[0222] Step 7, execute instructions: according to the type of instructions, execute the corresponding operations, such as reading temperature, adjusting power, etc.

[0223] Step 8, send data: send the execution results or other data that need to be uploaded to the master controller.

[0224] Step 9, loop: the slave controller loops through steps 5-8.

[0225] The slave controller software is mainly responsible for the following aspects:

[0226] Position recognition: Read the resistance voltage value connected to the inner ring of the positive female connector through the ADC channel, determine the position according to different voltage values, and realize position recognition.

[0227] Automatic generation of ID: Automatically generate a unique device ID according to the preset rules and position information.

[0228] Data collection: Collect data from temperature sensors.

[0229] Heating control: Adjust the heating power of the heating sheet according to the instructions of the main controller and the preset control algorithm.

[0230] Respond to the main controller's command: Receive and respond to the main controller's command, upload data or perform corresponding operations.

[0231] The main controller and the slave controller can communicate through single bus or other suitable communication protocols.

[0232] Among them, the slave controller software is mainly responsible for position recognition, automatic generation of ID, data collection, heating control and response to the main controller's command.

[0233] After the slave controller is powered on and initialized, the slave controller MCU reads the resistance voltage value connected to the inner ring of the positive female connector through the ADC channel. Because the resistance values of the female connectors in different positions are different, the voltage values read by the ADC are also different.

[0234] The slave controller determines the installation position of the current heating sheet according to the pre-set correspondence between resistance value (or voltage value) and position information.

[0235] Compare the read position information with the pre-stored position information (or device ID) in the EEPROM.

[0236] Generate a new device ID according to the current read position information. The generation rule of the device ID is pre-set, for example, the position number can be used as part of the device ID to ensure that the device ID of each position is unique.

[0237] The slave controller continuously listens to the bus and waits to receive the main controller's command. After receiving the command frame, parse the identifier of the command frame, extract the ID information, and compare it with the ID of the slave controller.

[0238] If matched: It means that the command is sent to the slave controller, and the next step is entered.

[0239] If not matched: It means that the command is not sent to the slave controller, so the command is ignored and the waiting continues.

[0240] If the ID matches, the master controller performs the corresponding operation according to the command type.

[0241] In addition, the main responsibility of the master controller is device management, data polling, control command sending and user interaction.

[0242] The master controller is powered on, and the program initialization starts. The master controller loads the preset device ID list from the internal memory (such as EEPROM or Flash), which contains the IDs of all possible installation positions and their corresponding position information.

[0243] The master controller starts the polling process and queries the device status one by one. The master controller selects the next device ID to be queried from the device list.

[0244] Send a query command to the device with this ID and record the current status of the device (online / offline, all devices are offline in the initial state).

[0245] The master controller waits for the response of the device. The master controller sends control commands to the device, such as setting the target temperature, adjusting the power, etc. Receive the response data returned by the device, read the temperature, power, status, etc. from it, and update the status information of the device in the device list.

[0246] The master device will poll the offline devices regularly and can identify the device access caused by hot plug in real time.

[0247] The above describes the utility model and its implementation, which is not limited. The drawings shown are only one of the embodiments of the utility model, and the actual structure is not limited. In general, if a person skilled in the art is inspired, without departing from the creative purpose of the utility model, without creative design, similar structure and examples of the technical scheme should belong to the protection scope of the utility model.
