Description

Technical Field

[0001] This utility model relates to the field of automotive energy-saving technology, and in particular to an energy-saving heating device for vehicles. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, new energy vehicles are gaining wider application in the automotive market due to their zero or low emissions. However, in cold climates, the driving range of new energy vehicles is significantly reduced due to the use of heating and air conditioning, a phenomenon that severely restricts their promotion and use.

[0003] Traditional air conditioning systems in new energy vehicles typically employ PTC (Positive Temperature Coefficient) heating technology or heat pump systems, with heating capacities ranging from 5kW to 7kW. While PTC heating technology offers the advantage of rapid heating, its energy conversion efficiency is relatively low, with significant losses occurring in the direct conversion of electrical energy into heat. Although heat pump systems theoretically have a higher energy efficiency ratio, their heating capacity drops drastically in cold environments (below -5°C), and the compressor is prone to malfunction due to prolonged high-load operation. Running the air conditioning for extended periods in cold weather consumes a large amount of electricity, significantly reducing the driving range of new energy vehicles and causing considerable inconvenience for users.

[0004] Furthermore, running the air conditioner for extended periods not only increases energy consumption but also poses safety hazards. Increased energy consumption puts a heavier workload on the vehicle's battery, leading to overheating and impacting battery lifespan and vehicle safety. Especially under conditions of frequent start-stop operation of the air conditioner, the battery's charging and discharging current fluctuates drastically, accelerating battery aging.

[0005] Currently, although there are some heating solutions for new energy vehicles on the market, most of them suffer from high energy consumption and unsatisfactory effects, and there is still room for improvement to meet the market's comprehensive needs for comfort and range of new energy vehicles.

This allows new energy vehicles to significantly reduce electricity consumption when using this device for heating in cold weather, effectively extending the vehicle's range and providing greater convenience for users' travel. Furthermore, by transferring heat through infrared radiation, it can quickly and effectively raise the local temperature inside the vehicle, allowing passengers to feel warmth in a short time and improving driving comfort. This localized heating method meets the actual heating needs of passengers while avoiding the energy waste caused by traditional air conditioners heating the entire vehicle interior. This device is directly connected to the new energy vehicle's built-in power supply, and the installation process is simple and quick, requiring no large-scale vehicle modifications.

[0030] refer to Figure 1 As shown, an energy-saving heating device for vehicles according to an embodiment of the present invention is specifically applied to new energy vehicles, including a heating element 100, a reflector 200, and a housing 300.

[0031] The heating element 100 is an infrared carbon fiber heating element, and both ends of the heating element 100 are electrically connected to the power supply. The reflector 200 is installed outside the heating element 100, and its shape is adapted to reflect and concentrate the heat generated by the heating element 100. The outer shell 300 is fitted outside the reflector 200.

[0032] For example, such as Figure 1As shown, the heating element 100 is an infrared carbon fiber heating tube, which is long and slender with a diameter of 8mm-12mm. Depending on the actual installation requirements, its length is typically set to 15cm-30cm. The two ends of the heating element 100 are electrically connected to the positive and negative terminals of a power supply via power cords 800. The heating element 100 is fixed inside the reflector 200 using screws. The reflector 200, used to mount the heating element 100, is made of a highly reflective material, such as magnesium-aluminum alloy. Its shape and structure are designed to effectively reflect and concentrate the heat generated by the infrared carbon fiber heating element, allowing the heat to be transferred more concentratedly in a specific direction. The reflector 200 has a V-shaped cross-section, and its length is adapted to the length of the heating element 100. An outer shell 300 surrounds the reflector 200, protecting both the heating element 100 and the reflector 200. The reflector 200 is connected to the outer shell 300 via a snap-fit, magnetic, or threaded connection. The outer casing 300 has the same shape as the reflector 200, meaning its cross-sectional shape is also V-shaped. A protective net 700 can be installed at the V-shaped opening of the outer casing 300. The protective net 700 is used to prevent human contact with the surface of the heating element 100, thus preventing burns. The inner surface of the outer casing 300 is fitted to the outer surface of the reflector 200, and a ring of heat-insulating sealant is applied to the contact area between the inner surface of the outer casing 300 and the outer surface of the reflector 200. The outer casing 300 is fixed inside the vehicle. The outer casing 300 is made of high-strength and high-temperature resistant engineering plastics, such as polyphenylene sulfide. Thermally conductive fillers, such as boron nitride or aluminum oxide, can also be added to the engineering plastic.

[0033] Specifically, the heating element 100 uses an infrared carbon fiber heating tube. Both ends of the heating element 100 are connected to the car's cigarette lighter socket via a power cord 800, rapidly generating and transferring heat for efficient heating. The power cord 800 is a high-voltage resistant wire or directly connected to the car's 12V battery, operating at a low voltage of 12V with a power of 50W. It features low energy consumption and high heat generation, using automotive-grade wire with good infrared insulation. The rated voltage of the power cord 800 must be greater than the operating voltage (12V), and the rated current must meet the maximum operating current requirement of the device, using a wire with a rated current of not less than 10A. Compared to the traditional 5kW heating air conditioning system used in new energy vehicles, this device, using a low-energy-consumption, high-heat infrared carbon fiber heating tube, has a power of only 50W. Clearly, using this device can save 100 times the energy consumption. This allows new energy vehicles to significantly reduce energy consumption when using this device for heating in cold weather, effectively extending the vehicle's range and providing greater convenience for users. Moreover, during use, drivers don't need to turn on the car's heating system; simply turning on this device can raise the car's interior temperature by at least 10°C within half an hour. By transferring heat through infrared radiation, it quickly and effectively raises the temperature in specific areas of the vehicle, allowing passengers to feel warm in a short time and improving comfort. Simultaneously, this localized heating method meets the actual heating needs of passengers, avoiding the energy waste caused by traditional air conditioning systems that heat the entire car interior. This device provides warmth for the driver while significantly saving electricity, thus solving the problem of high power consumption and short driving range in new energy vehicles during cold weather when the air conditioning is on.

[0034] Furthermore, when connecting the heating element 100 to the cigarette lighter socket of a new energy vehicle, a compatible cigarette lighter plug cable must be used. Before inserting it into the cigarette lighter socket, check the plug and the inside of the socket for foreign objects to ensure a reliable connection. If the heating element 100 is directly connected to the vehicle's 12V battery, the negative terminal of the battery should be disconnected first to prevent a short circuit during connection. During connection, connect the positive power cable of the heating element 100 to the positive terminal of the battery and the negative power cable to the negative terminal. After connection, use cable ties to secure the power cable 800 to the vehicle's wiring harness to prevent the cable from swaying. After connection, reconnect the negative terminal of the vehicle battery. By directly connecting this device to the cigarette lighter socket or 12V battery of a new energy vehicle, the installation process is simple and quick, requiring no major vehicle modifications. The adjustable temperature design of the power switch 600 allows users to easily adjust the heating temperature according to their actual needs, and the operation is simple and easy to understand.

[0035] The heating element 100 is externally encased in a transparent or semi-transparent high-temperature resistant quartz glass tube with a smooth and uniform wall. This effectively protects the internal carbon fiber heating element and provides excellent light transmittance, facilitating the smooth radiation of infrared heat to the outside of the heating element 100. The high-temperature resistant quartz glass tube is made from high-purity quartz sand through melting and tube drawing processes. This quartz glass tube features high light transmittance, high temperature resistance (withstanding temperatures above 600℃), and strong chemical stability, effectively protecting the internal carbon fiber heating element while ensuring smooth infrared radiation. High-performance polyacrylonitrile-based carbon fiber is selected as the base material. By optimizing the precursor fiber preparation process, such as improving the spinning solution formula or adjusting the spinning temperature and speed, the microstructure of the carbon fiber becomes more regular, and the degree of graphitization is higher, resulting in better electrical and thermal conductivity. Furthermore, surface modification technology can be applied to the carbon fiber to introduce specific functional groups or coatings on the surface, improving overall performance and further enhancing its oxidation resistance and stability.

[0036] Furthermore, the two ends of the heating element 100 are connected to the positive and negative terminals of the power supply, respectively. The electrodes at both ends of the heating element 100 are generally made of new materials with good conductivity and oxidation resistance. For example, silver-plated or nickel-plated copper alloy electrodes are used. A uniform silver or nickel plating layer is formed on the surface of the copper substrate through an electroplating process. This ensures a good electrical connection between the electrode and the carbon fiber filament, and also prevents the electrode from oxidizing in high temperature and humid environments, thus extending its service life.

[0037] Meanwhile, a special heating coating material is coated on the surface of the carbon fiber filaments of the heating tube 100. This coating is usually composed of a metal oxide (such as tin oxide or indium oxide) and an organic polymer material, which can optimize the heating performance, make the heat distribution more uniform, and enhance the ability to radiate infrared rays, thereby improving the heating efficiency.

[0038] Furthermore, when the heating element 100 is fixed inside the reflector 200 with screws, the screws should be made of high-temperature resistant and rust-proof materials, such as stainless steel screws. When tightening the screws, the torque must be carefully controlled to prevent damage to the heating element 100 or the reflector 200 due to excessive torque; the torque is generally controlled between 0.5 N·m and 1 N·m. When installing the heating element 100 inside the reflector 200, the distance between the heating element 100 and the inner wall of the reflector 200 must be uniform to avoid uneven heat reflection due to inconsistent spacing.

[0039] Furthermore, to effectively reflect and concentrate heat, the reflector 200 is designed with a parabolic shape, similar to a lampshade. An infrared carbon fiber heating tube is placed at the focal point, and a protective mesh 700 is installed at the opening, allowing heat to be emitted as a parallel beam, improving heat utilization efficiency. A shape memory alloy wire or piezoelectric ceramic driving element is also installed on the surface of the reflector 200. This driving element is electrically connected to a sensor, which monitors ambient temperature and / or human position in real time. When a change in human position or fluctuation in ambient temperature is detected, the driving element is controlled to deform the reflector 200, dynamically adjusting the curvature and angle of the reflective surface to ensure precise heat radiation to the target area. For example, when movement of occupants is detected, the reflector 200 automatically adjusts its angle, continuously delivering heat to the driver's legs and feet.

[0040] In addition, the outer casing 300 is fitted over the reflector 200 to protect the internal heating element 100 and reflector 200 from damage caused by external impacts or pressure. Before fitting the outer casing 300 over the reflector 200, a layer of sealant, such as silicone sealant, must be applied to the contact area to enhance the device's sealing and prevent dust or moisture from entering and affecting its performance. The sealant application width is approximately 5 mm, and the thickness is approximately 1 mm–2 mm. After installation, check that the outer casing 300 completely covers the reflector 200, that the edges are smooth, and that there are no warping or gaps. The outer casing 300 also has a certain degree of insulation to ensure safety during use. The outer casing 300 is made of high-strength and high-temperature resistant plastic material, and its surface is treated with an anti-slip coating for easy installation and disassembly. An elastic buffer layer is installed inside the outer casing 300. This elastic buffer layer is made of honeycomb rubber, spring array, or flexible silicone material. When subjected to external impacts or pressure, the buffer layer can effectively absorb the impact force and prevent damage to the heating element 100. Meanwhile, the buffer layer has a compressible structure that can compress its volume when not in use, making it easy to store and transport.

[0041] To improve heat dissipation, the roughness of the outer surfaces of the reflector 200 and the housing 300 is increased to enhance air adhesion between them, promoting airflow and thus improving heat dissipation. However, the surface roughness should not be too high, otherwise it will increase the adhesion of dust and other contaminants, affecting heat dissipation and aesthetics.

[0042] In some specific embodiments of this utility model, a temperature protector 400 and a fuse 500 are connected in series at one end of the heating element 100 and connected to a power source. The temperature protector 400 and the fuse 500 provide dual protection for the operating temperature and circuit of this device. When the temperature is too high or a circuit malfunction occurs, the temperature protector 400 and the fuse 500 will activate in time to cut off the circuit and prevent safety accidents.

[0043] In this design, the power cord 800 of the heating element 100 is connected in series with a temperature protector 400, which is mounted on the reflector 200. The function of the temperature protector 400 is to monitor the operating temperature of the heating element 100 in real time. When the temperature exceeds the set safe temperature value, the temperature protector 400 will automatically cut off the circuit and stop the operation of the heating element 100 to prevent safety accidents caused by overheating. The temperature protector 400 adopts, but is not limited to, a bimetallic strip temperature switch 600, which features simple structure and reliable operation.

[0044] Furthermore, the temperature-sensing surface of the temperature protector 400 should maintain the optimal monitoring distance from the heating element 100. Actual testing showed that the temperature monitoring effect is best when the distance between the temperature-sensing surface and the surface of the heating element 100 is maintained at 1cm-2cm. During installation, thermally conductive silicone is used to attach the temperature protector 400 to the reflector 200, ensuring both good thermal conductivity and a secure fixation.

[0045] Furthermore, the temperature protector 400 is connected in series with the fuse 500 via the power cord 800. The fuse 500 is connected to the cigarette lighter socket of the new energy vehicle or directly to the 12V battery in the vehicle via the power cord 800. As an overload protection component for the circuit, the fuse 500 will automatically melt and disconnect the circuit when an overload or short circuit occurs, protecting the safety of the entire device and the vehicle's electrical system.

[0046] In some specific embodiments of this utility model, a switch 600 is connected in series at one end of the heating element 100. Specifically, one end of the switch 600 is connected in series with the temperature protector 400, and the other end is connected in series with the fuse 500. The switch 600 is used to adjust the temperature. According to actual needs, the user adjusts the working power of the heating element 100 through the switch 600, thereby controlling the heating temperature of the device. The switch 600 is, but is not limited to, a rotary switch. The user can switch between different power levels by rotating the knob, thereby achieving stepless temperature adjustment.

[0047] In some specific embodiments of this utility model, the reflector 200 and the outer shell 300 are nested structures, with the outer layer being a protective cover and the inner layer being the reflector 200. The two layers at both ends of the reflector 200 and the outer shell 300 are connected by a rotating bearing, which enables the reflector 200 to be freely adjusted to 360°, and precisely controls the direction of heat radiation.

[0048] In some specific embodiments of this utility model, the reflector 200 and the outer shell 300 are designed as an integrated composite structure, with a heat-insulating interlayer between the reflector 200 and the outer shell 300, and the heat-insulating interlayer is filled with heat-insulating material. The heat-insulating material is aerogel, a high-efficiency heat-insulating material. This structure can both concentrate the reflection of infrared rays and effectively block the transfer of heat to the outside, avoiding excessively high surface temperature of the outer shell 300, improving safety in use, and simplifying the overall installation process.

[0049] In some specific embodiments of this utility model, the reflector 200 and / or the outer casing 300 are equipped with heat dissipation fins to increase the heat dissipation area and thus improve the thermal efficiency of the device. The fins are serrated or wavy, and their height is adapted to the installation space of the device. The spacing between the fins is uniform, which allows air to flow smoothly between the fins, further increasing the heat dissipation area and reducing air turbulence, thereby improving the heat dissipation effect.

[0050] In some specific embodiments of this utility model, the reflector 200 and / or the outer shell 300 are coated with a heat dissipation coating. The heat dissipation coating is, but is not limited to, a nano heat dissipation coating, which has a high infrared emissivity and can radiate heat away in the form of infrared rays, thereby improving heat dissipation efficiency.

[0051] In some specific embodiments of this utility model, ventilation holes are provided on the surface of the outer casing 300 to promote air circulation. The size, number, and location of the ventilation holes should be optimized according to the power and heat dissipation requirements of the heating element 100. For example, ventilation holes are provided on both the upper and lower surfaces of the outer casing 300, utilizing the principle of hot air rising and cold air sinking to form natural convection and accelerate heat dissipation. A ventilation channel is provided between the reflector 200 and the outer casing 300 to allow air to flow between them and carry away heat.

[0052] In some specific embodiments of this utility model, each reflector 200 and the outer shell 300 constitute an independent unit, and multiple independent units are spliced ​​together using snap-fit, slot, or magnetic interface. Users can freely increase or decrease the number of modules or change the splicing shape according to actual installation space and heating requirements, which can adapt to the needs of different vehicle models or different installation locations, and also facilitates the production, transportation, and maintenance of this device. For example, in large buses or small cars, the splicing of independent units achieves adaptation to different vehicle sizes.

[0053] Furthermore, the exterior design of the reflector 200 and the outer shell 300 is deeply integrated with the style of the car's interior, using the same or similar materials, colors, and textures. For example, for luxury models, the outer shell 300 is wrapped in genuine leather with exquisite stitching; for technologically advanced models, the outer shell 300 uses a transparent material with a frosted texture, embedding LED light strips inside, which not only meets the heating function requirements but also becomes part of the interior decoration, enhancing the aesthetics and texture of the entire vehicle's interior.

[0054] In addition, multiple functional components are integrated on the surface of the outer shell 300. For example, an ambient light strip is embedded on the edge of the protective cover, which not only enhances the product's aesthetics but also serves as a lighting indicator for nighttime use; or a small fan is installed to accelerate the transfer of heat generated by the heating element 100 through forced convection, thereby improving heating efficiency; and a wireless charging module is integrated on the surface of the outer shell 300, which makes it convenient for users to charge mobile phones and other devices, achieving multiple uses in one product.

[0055] In addition, sound-absorbing material, such as sound-absorbing cotton or foam metal, is added between the reflector 200 and the housing 300 to reduce the subtle vibration noise and airflow noise generated when the heating element 100 is working. Furthermore, at least two reinforcing ribs are provided inside the housing 300 to fix the reflector 200, reduce friction and resonance between the reflector 200 and the housing 300, and create a quiet and comfortable in-vehicle environment for drivers and passengers.

[0056] In some specific embodiments of this utility model, the outer casing 300 is installed below the steering wheel in the car's driver's cab via an installation interface. Specifically, the installation interface includes, but is not limited to, a magnetic or snap-fit ​​connection structure. The outer casing 300 is magnetically or snap-fitted to the structure below the steering wheel in the car's driver's cab, allowing the device to be quickly installed in a specific location in the car without tools. Furthermore, the installation is secure and reliable, and it is not easily loosened due to vehicle vibrations. This structure also facilitates installation and disassembly, making it convenient for users to clean, maintain, or replace the device, meeting the personalized needs of different car models and users. Installing the device below the steering wheel, directly opposite the feet, can directly warm the feet of the driver and passengers, allowing them to feel warmth in a short time and improving driving comfort. Simultaneously, this localized heating method can also meet the actual heating needs of the driver and passengers, avoiding the energy waste caused by traditional air conditioning heating the entire interior space.

[0057] In some specific embodiments of this utility model, it can also be explained that a temperature sensor and an intelligent control chip can be embedded within the reflector 200 or the housing 300 to monitor the vehicle interior temperature and the operating temperature of the heating element 100 in real time. When the vehicle interior temperature reaches a preset comfort value, the power of the heating element 100 is automatically reduced; if an excessively high local temperature is detected, such as an abnormal temperature in the area near the heating element 100, the control chip can adjust the angle of the reflector 200 to change the direction of heat radiation and achieve precise temperature control. Simultaneously, through linkage with the vehicle's central control system, users can remotely adjust the heating device temperature and the status of the on / off switch 600 on the vehicle's screen, improving ease of use.
