Description

Technical Field

[0001] This invention relates to the field of electrothermal wearable device technology, specifically to a portable DC-DC boost-powered electrothermal wearable product. It uses 1-4 sets of low-voltage batteries as independent power sources, relying on a mature and universally applicable DC-DC boost module / circuit for voltage boosting, and provides a stable output of 24V-60V. This is specifically designed to provide stable heating power for electrothermal loads such as electrothermal clothing, electrothermal pants, and wearable products with localized body heating. This invention is suitable for various convenient activity scenarios such as outdoor travel, daily commuting, static warmth preservation, and light outdoor work, effectively solving the technical pain points of traditional electrothermal wearable products, such as fixed power supply, limited mobility, and high modification and usage costs. It represents a low-cost, universal, and multi-battery compatible electrothermal wearable power supply technology solution. Background Technology

[0002] During the cold season, electrically heated wearable thermal products are core equipment for personal warmth protection in winter, widely applicable to daily warmth for the general public, outdoor workers, commuters, and other scenarios. However, the power supply solutions of mainstream electrically heated wearable products on the market currently have significant flaws, resulting in extremely poor product compatibility and cost-effectiveness.

[0003] Traditional high-end electric heating wearable products mostly adopt high-voltage, high-power power supply solutions, requiring multiple series and parallel battery packs and customized high-voltage boost circuits. The overall equipment cost is high, the structure is complex, the size is large, and the maintenance and replacement are difficult, making them unsuitable for the mass-market, affordable consumer market. On the other hand, low-end electric heating wearable products mostly use a direct battery power supply mode with low voltage, without a boost structure. The output voltage is low and the heating power is insufficient, which directly leads to slow heating, poor heat preservation, and uneven heating, failing to meet the warmth requirements in low-temperature environments.

[0004] Meanwhile, existing patented solutions for portable, boost-powered wearable heating systems mostly limit high-voltage output above 60V, power supply from four or more battery packs, and require customized boost circuits. While these solutions address the issues of portable power supply and heating efficiency, they suffer from high equipment barriers, poor versatility, and high costs, failing to meet the widespread demand for low-power, small-sized wearable heating products. Furthermore, they generally limit power supply to a single lithium battery, making them unsuitable for future iterations of new battery technologies. Currently, the industry lacks a low-cost, portable power supply solution that relies on mature, universal components, uses a limited number of batteries (1-4 packs) for universal power supply, maintains a precise low-voltage boost range of 24V-60V, and is compatible with heating loads. Based on this, this invention proposes a differentiated, low-cost, universal, and multi-battery compatible technical solution. Summary of the Invention

[0005] The purpose of this invention is to overcome the technical shortcomings of existing technologies, such as high cost and complex structure of high-end electrothermal wearable products, low efficiency of low-voltage heating in low-end products, and high barriers to entry, poor versatility, limited battery types, and incompatibility with low-power wearable products in existing boost power supply patent solutions. This invention provides a portable DC-DC boost-powered electrothermal wearable product. It uses 1-4 sets of a small number of general-purpose batteries as the sole power source, not limited to lithium batteries, and is compatible with various civilian rechargeable batteries. It reuses commercially available mature and mass-produced DC-DC boost modules / conventional boost circuits to precisely boost the voltage to 24V-60V to suit the electrothermal load. While ensuring stable heating and free mobility, it significantly reduces product development, production, and maintenance costs. Simultaneously, it completely circumvents the patent protection scope of existing high-voltage, multi-battery-pack, and customized circuits, achieving a low-cost, widespread, and compatible mobile power supply solution for electrothermal wearables that is compatible with future battery technology iterations. Technical solution

[0006] To achieve the above-mentioned objectives, the present invention adopts the following differentiated low-cost technical solution: A portable DC-DC boost-powered wearable heating product includes 1-4 battery packs 1 (labeled), a mature mass-produced DC-DC boost module / conventional boost circuit 2 (labeled), a temperature control circuit 3 (labeled), and a wearable body 4 (labeled) with a heating load. The 1-4 battery packs are the sole power source for the entire device. The output of the battery packs is electrically connected to the input of the DC-DC boost module / circuit. The output of the DC-DC boost module / circuit is electrically connected to the temperature control circuit, and the temperature control circuit is electrically connected to the heating load of the wearable body. The DC-DC boost module / circuit uses industry-standard, mature mass-produced components without customization. It accurately boosts and stabilizes the low-voltage output voltage of the 1-4 battery packs to 24V-60V DC, providing stable heating power specifically for the heating load of heating clothing, heating pants, and locally heated wearable products, achieving low-cost, portable, and unrestricted wearable heating and heat preservation.

[0007] Furthermore, the battery pack consists of 1, 2, 3, or 4 independent battery modules 1, using conventional series or parallel combinations, eliminating the need for stacking more than 4 battery modules. The batteries are commercially available rechargeable battery cells, including but not limited to lithium batteries, nickel-metal hydride batteries, and new solid-state batteries, which are suitable for civilian low-voltage energy storage. There is no need for customized high-voltage battery packs. The voltage and capacity of a single battery can be flexibly selected according to the requirements of the thermal load. The battery is compact, has low procurement costs, and is easy to replace, meeting the lightweight requirements of wearable products.

[0008] Furthermore, the DC-DC boost module / circuit 2 is a commercially available, mass-produced, general-purpose component. It adopts a conventional Boost boost basic circuit structure, eliminating the need for additional customized modifications such as optimized inductors or dedicated switching modules. The component is highly versatile, has a large market supply, and is inexpensive. The DC-DC boost module / circuit has a fixed regulated output range of 24V~60V, which is precisely adapted to electric and thermal loads. It abandons the existing high-voltage output schemes above 60V, ensuring stable circuit operation, low failure rate, and eliminating the need for complex debugging, thus significantly reducing production assembly and subsequent maintenance costs.

[0009] Furthermore, the temperature control circuit adopts a low-cost pure hardware control circuit or a simple MCU control circuit 3. It preferentially uses general-purpose components such as resistors, capacitors, and ordinary temperature control switches to form a pure hardware circuit, which has a very simple structure and low cost. Based on the stable boost output characteristics of 24V~60V, the temperature control circuit of this invention has flexible temperature control expansion capability, supports two or more levels of multi-level temperature control or stepless constant temperature adjustment, and can freely configure the number of levels and constant temperature range according to different product scenarios. At the same time, it is equipped with automatic power-off protection function for overheating and overload, and can dynamically match the boost output voltage to accurately adjust the heating power of the electric heating load to avoid overheating or insufficient heating. While ensuring the safety of use and the accuracy of temperature control, it maximizes the control of hardware costs.

[0010] Furthermore, the wearable body is an electric heating garment, electric heating pants, or wearable product for localized human body heating, including electric heating waist support, electric heating knee support, and electric heating shoulder support, etc., with electric heating load 4. The electric heating load adopts conventional low-power heating elements such as carbon fiber film, graphene film, and fine metal heating wire. It is deployed locally or evenly across the entire body according to the parts of the body that are prone to cold. The power of the heating load is matched to the 24V~60V low-voltage boost power supply range, which is suitable for the low-voltage boost stable power supply conditions of this invention, ensuring uniform and efficient heating and warmth preservation effects. Beneficial effects

[0011] Compared with existing technologies and filed patent solutions, this invention has significant advantages in differentiation and low cost, while effectively circumventing the scope of existing patent protection, as detailed below: 1. The solution is highly differentiated and completely avoids existing patent barriers: The core difference between this invention and the existing high-voltage boost and multi-battery pack patent solutions is that it is limited to using 1 to 4 groups of small batteries for power supply, a medium-low voltage boost range of 24V to 60V, and a mature and universal DC-DC circuit without customization. It abandons the core protection features of the original patents, such as high voltage above 60V, more than 4 battery packs, and customized and optimized boost structure. The overall technical solution is completely independent and has no risk of infringement.

[0013] 3. Extremely low cost, suitable for mass market: The core components of this invention all use mature mass-produced general-purpose parts on the market. 1 to 4 sets of general-purpose batteries do not require customization of high-voltage battery packs, DC-DC boost modules do not require circuit modification and optimization, and the temperature control circuit adopts an extremely simple hardware structure. Compared with the existing customized high-voltage solutions, the material cost, production and debugging cost and maintenance cost are greatly reduced, completely solving the pain points of high cost and difficulty in popularization of existing electric heating boost wearable products.

[0014] 4. Mature and stable technology with extremely low failure rate: This invention relies on the industry-standard and mature 24V~60V low-voltage DC-DC boost technology. The circuit topology is simple and the technology is mature. There are no stability risks associated with new circuits. The voltage conversion is stable and the power consumption is low during operation. It can continuously provide stable power to the electric heating load, with uniform heating and precise temperature control. The product reliability is far higher than that of customized circuits.

[0015] 5. Lightweight, widely adaptable, and easy to use: The 1-4 battery packs are small in size and lightweight, meeting the lightweight requirements of wearable products. They can be hidden inside clothing and protective gear. The 24V~60V voltage range is precisely compatible with all civilian low-power electric heating wearable products. It is compatible with electric heating clothing, electric heating pants, and various local heating protective gear. It is suitable for various scenarios such as daily warmth, outdoor commuting, and light work. It completely eliminates the constraints of fixed power sources and is highly convenient for mobile use.

[0016] 6. Strong temperature control expandability and safe adaptation to various scenarios: This invention is equipped with a universal adjustable temperature control circuit, supporting two control modes: multi-level graded temperature control and stepless constant temperature control. The number of levels can be flexibly expanded to adapt to different ambient temperatures and people's warmth needs, achieving precise heating control. The system comes standard with automatic power-off protection against overheating and overload, and the whole machine adopts 24V~60V civilian safety low voltage output, eliminating high voltage safety hazards. The overall structure is easy to assemble, and the components can be replaced individually, resulting in low operating costs, high reliability, and suitability for various civilian wearable warmth scenarios.

[0018] In this invention, battery packs 1 to 4 serve as the sole power source for the entire device, connected to a mature DC-DC boost module / circuit 2, providing low-voltage input power to the boost unit. The DC-DC boost module / circuit 2 stabilizes and boosts the low-voltage power to 24V~60V, outputting it to the temperature control circuit 3. The temperature control circuit 3 adjusts the output power and temperature through switches and temperature control devices, ultimately powering the wearable body 4 with an electric heat load, achieving portable, low-cost heating and insulation. Detailed Implementation

[0019] The present invention will be further described in detail below with reference to specific embodiments. The present invention is limited to 1 to 4 sets of general-purpose battery power supply and 24V to 60V mature DC-DC boost range. All embodiments use general mass-produced components without customized modifications, highlighting the advantages of low cost, universality and multi-battery adaptability, and is completely different from the existing high-voltage multi-battery patent solutions.

[0020] This embodiment provides a low-cost electric heating thermal insulation garment, which includes two universal battery packs, a commercially available standard DC-DC boost module, a pure hardware temperature control circuit, and the thermal insulation garment body.

[0021] The power supply uses two sets of conventional civilian battery packs, each with an output voltage of 7.4V. The two sets are connected in parallel to output 7.4V low-voltage DC power with a capacity of 4000mAh. The batteries are general mass-produced single cells, requiring no custom processing. The procurement and replacement costs are extremely low. The batteries are small in size and can be stored in the inside pocket of clothing, meeting the daily need for 3 to 10 hours of continuous warmth and power supply.

[0022] The DC-DC boost module is a mature and widely used Boost boost module in the market. It does not require any circuit structure optimization or customization. It directly reuses existing mature technology and stably boosts and regulates the 7.4V low-voltage input to 36V, which is within the core boost range of 24V~60V. The boost efficiency is stable at over 82%, with low power consumption, no debugging threshold, and low cost for bulk purchase.

[0023] The temperature control circuit adopts a low-cost, pure hardware control circuit, consisting of a general-purpose temperature control resistor, a toggle switch or rheostat, and an overheat protection fuse. Its structure is extremely simple and cost-effective. The circuit supports multi-level temperature control expansion. This embodiment is configured by default with three conventional temperature control levels: low temperature, medium temperature, and high temperature. More subdivided levels or stepless constant temperature mode can be expanded according to product needs. The circuit has a built-in overheat power-off protection mechanism, which automatically cuts off the output when the temperature of the heating load abnormally exceeds the standard, eliminating high-temperature safety hazards. Compared with customized precision temperature control solutions, it significantly reduces hardware costs while meeting the temperature control needs of multiple scenarios.

[0024] The inner lining of the electric heating thermal garment is equipped with a low-power carbon fiber heating film, which is mainly placed in the back and waist areas that are prone to cold. The heating film power is adapted to a 36V power supply voltage, and the heating is uniform and stable. It is compatible with the low-voltage boost power supply system of this invention and can stably realize the wearable heating and thermal insulation function.

[0025] When in use, after fully charging the two battery packs, connect them to the boost module, turn on the temperature control circuit switch, and the mature DC-DC module will stably output 36V voltage to power the heating film, quickly achieving temperature rise and heat preservation. Users can move freely and wear it without the constraints of a power cord. The overall product has a very high cost performance and is suitable for popular use.

[0026] This embodiment provides a simple and low-cost electric heating thermal pants, including a single battery, a general DC-DC boost circuit, a simple temperature control circuit, and the electric heating thermal pants body.

[0027] The power supply is a single civilian battery with an output voltage of 3.7V and a capacity of 3500mAh. It is the smallest power supply unit in this solution, with a minimal structure and light weight. It can be directly fixed in the hidden pocket of the waistband of pants to meet the needs of daily commuting and keeping warm.

[0028] The DC-DC boost circuit uses a commercially available miniature boost circuit board, which is a mature and standardized device in the industry. It does not require structural optimization or parameter tuning, and accurately boosts the 3.7V voltage to 24V. It is suitable for the low-power heating wire load of electric heating pants. The circuit is small in size, has a low failure rate, and has extremely low mass production cost.

[0029] The temperature control circuit adopts a low-cost, pure hardware constant temperature control structure, defaulting to a fixed constant temperature output mode, suitable for minimalist, low-cost mass production scenarios; it also retains multi-level temperature control and stepless constant temperature expansion capabilities, and features a built-in thermistor overheat protection function to ensure safe use. This structure has fewer components, is simple to assemble, and has a low failure rate, which can minimize product production costs and is suitable for affordable, widely used electric heating wearable products.

[0030] The electric heating thermal pants use flexible, low-power metal heating wires, which are concentrated in the core warming areas of the knees and waist. They are compatible with 24V low-voltage power supply, providing gentle and even heating. The fabric is elastic and fits the human body, without affecting daily walking or cycling activities.

[0031] This embodiment provides a localized heating electric lumbar support, including 3 battery packs, a wide voltage adaptable mature DC-DC boost module, a simple MCU temperature control circuit, and the lumbar support body.

[0032] The power supply uses a combination of three batteries in series, with each battery providing 3.7V and the three batteries in series outputting 11.1V. It has a capacity of 5000mAh, providing longer battery life and is suitable for long-term outdoor static insulation scenarios.

[0033] The DC-DC boost module is a mature, wide-voltage mass-produced module that can stably boost and regulate the input low-voltage electricity to 60V, which is the upper limit of the boost range of this invention. It is perfectly adapted to high-power local heating protective gear loads. The module is a general standard part, requiring no customized modification, and the technology is mature and reliable.

[0034] The temperature control circuit adopts a simple and low-cost MCU control unit, which supports multi-level fine-tuning temperature control switching and stepless constant temperature precision adjustment. It has strong temperature control expandability and can be adapted to the full range of 24V~60V boost output conditions, taking into account both high-precision heating control and safety of use. Compared with high-end customized MCU temperature control systems, this solution achieves multi-mode temperature control functions with extremely simple circuitry, which greatly reduces R&D and mass production costs.

[0035] The lumbar support body is lined with a graphene low-power heating film that conforms to the curve of the human waist. It has a large heating area and uniform temperature. It is compatible with the low-voltage boost power supply conditions of the present invention in the full range of 24V~60V. It is easy to disassemble and maintain and can meet the requirements of long-term stable use.

[0036] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art can make various modifications and variations based on the core features of 24V~60V boost voltage range, 1~4 sets of battery power supply, and universal battery compatibility without departing from the spirit and essence of the present invention. All such modifications and variations should fall within the protection scope of the present invention.
