Description

Technical Field

[0001] The present invention belongs to the technical field of automobile atmosphere lamps, and in particular relates to an adaptive automobile atmosphere lamp system and a power source manufacturing process. Background Art

[0002] With the development of the automotive interior design field, lighting plays an increasingly important role in improving the quality of a car's interior. Currently, ambient lighting is commonly used for vehicle interior lighting. It can achieve a variety of colors and brightness levels, allowing users to set different color and brightness effects according to their personal preferences and needs, thereby contributing to the interior decoration and atmosphere. Ambient light sources are typically installed in the form of light strips in locations such as the dashboard, center console, and door armrests. The current existing technology for achieving optical effects in automotive interior ambient lighting employs a lamp head arrangement that installs LED modules at one or both ends of the light guide, powered by the vehicle's battery.

[0003] However, the electronic assistance and lighting configurations in cars consume approximately 10% of the battery's energy to operate, and the use of ambient lighting further increases the car's energy consumption, which is not environmentally friendly. Furthermore, ambient lighting is only used for interior decoration, and the existing front and rear lights have a single function, with only two lighting modes: high beam and low beam, which cannot effectively serve as a warning to vehicles behind. If a car or truck driver travels at high speed for long periods of time in an environment with single-brightness headlights, they will suffer from visual fatigue from following vehicles, which can easily lead to traffic accidents.

[0004] Triboelectricity is electricity generated by friction between objects. It's one of the most common phenomena in nature, but it's often overlooked because it's difficult to harvest and utilize. If triboelectricity could be used to generate electricity in self-generating devices to power ambient lighting, it would undoubtedly reduce vehicle energy consumption.

[0005] To date, micro-electrostatic generators have been successfully developed and are widely used in the field of microelectromechanical systems. However, their design is primarily based on inorganic silicon materials, and their fabrication requires complex processes and precise operation. The entire device requires large-scale equipment and specialized production conditions, resulting in high costs that hinder its commercialization and everyday use. Therefore, how to manufacture a triboelectric generator, especially how to create it using simple processes, is a pressing technical challenge. Summary of the Invention

[0010] Preferably, the rotor is made of a plurality of regular fan-shaped oxygen-free copper sheets that are circumferentially bonded to a second FR4 glass fiber board at intervals.

[0011] Preferably, the rectifier circuit module is composed of a rectifier conversion module, a rectifier step-down module and a rectifier feedback module. The rectifier conversion module converts the AC power generated by the power source module into DC power through a bridge rectifier circuit composed of four diodes. The rectifier step-down module steps down the DC power through the interconnection of chips, diodes, inductors and transformers. The rectifier feedback module constitutes a feedback circuit through the interconnection of resistors, capacitors, inductors and diodes to achieve the function of stabilizing the working state of the step-down module.

[0012] Preferably, the circuit driving module is composed of a chip voltage stabilizing module, an LED lamp structure module, and a transistor threshold module.

[0027] Installation location of triboelectric devices in automobiles

[0028] The current national standards related to this system include GB 4785-2019 "Regulations for the Installation of External Lighting and Light Signaling Devices for Motor Vehicles and Trailers," GB 11567-2017 "Requirements for Side and Rear Lower Protection of Motor Vehicles and Trailers," GB 25991-2010 "LED Headlamps for Motor Vehicles," and GB / T 23921-2009 "Axles for Three-Wheeled Vehicles and Low-Speed ​​Trucks." Comparing these standards with the national standards revealed that installing this system will not affect the normal function of the vehicle. The system's small size and light weight meet the installation standards. Based on these national standards, we propose the following three reasonable installation solutions:

[0029] (1) The whole package is fixed to the bottom of the vehicle with rivets (this solution is suitable for vehicles without bottom sealing). It can be installed on the rear subframe. When installed, it is embedded, half of it is inserted and half of it is exposed (about 2.5 cm);

[0030] (2) Use instant glue to glue the system chassis to the car's engine lower guard plate (iron) and deflector (plastic), which can also support the operation of the system (on the inclined surface in front of the bottom of the car);

[0031] (3) There are some mounting holes on the chassis itself, whether it is the longitudinal beam or the cross beam. Most frames are still riveted, so some mounting holes will be reserved. Therefore, the entire system can be packaged and installed on the unoccupied mounting holes of the longitudinal beam.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1) This system uses a triboelectric nanogenerator as an energy generation and collection device, achieving carbon-free and environmentally friendly results. Wind energy is converted into mechanical energy and then into electrical energy to ensure the operation of the LED ambient light, completely avoiding problems such as resource waste, low utilization rate, and environmental pollution.

[0034] 2) The triboelectric power generation device of the present invention utilizes a periodic noble metal (copper, silver, gold) lateral cantilever structure, optimizing the spacing, number and size of the periodic lateral cantilevers, and the nanocones, nanowires, and microvoids of the lateral cantilever surface coating. This allows the thin-film triboelectric device to convert mechanical friction energy into electrical energy, improving the internal conversion efficiency of the triboelectric device and significantly simplifying and optimizing the overall circuit module.

[0035] 3) This system can control the number and color of LED ambient lights according to vehicle speed, achieving adaptive changes in the system, serving as a warning to drivers of the vehicle and following vehicles, preventing driver visual fatigue, improving driving safety, and reducing the risk of traffic accidents;

[0036] 4) The LED ambient light of this system will not light up when the car is not started. After the car is started, the LED ambient light will light up accordingly as the speed increases, avoiding the influence of environmental factors and extending the life of the LED light. The key point is to add a threshold switch in the drive circuit, which cleverly realizes that the system does not work when the car is not started;

[0037] 5) This system is small in size and easy to be installed in various locations without affecting driving safety. It can also be used in aerospace, military and other fields in the future. It has low cost, which is conducive to large-scale production in factories and easy to promote. It is conducive to continuously launching new products to the market, continuously improving the knowledge and technological content of products, reducing costs and thus increasing customer consumption value, improving product market competitiveness and market share, and timely opening up new market areas to bring huge economic benefits to the company.

[0056] The present invention will be further explained below with reference to the accompanying drawings to facilitate better understanding by those skilled in the art.

[0057] Example 1

[0058] like Figure 1-18 The adaptive automotive ambient lighting system, shown in Figure 1, includes a power source module A, a rectifier circuit module B electrically connected to the output of power source module A, and a circuit driver module C electrically connected to rectifier circuit module B. The power source module A and rectifier circuit module B are mounted on the vehicle frame, while the circuit driver module C is mounted on the rear lights or behind the chassis. Power source module A powers the ambient lighting, generating frictional charge as long as the vehicle is in motion, addressing the battery consumption and resource waste associated with existing technologies.

[0059] In this embodiment, the power source module A employs a triboelectric nanogenerator. Its triboelectric components include a fan with a rod 1, an upper cover 2, an oxygen-free copper sheet 3, a fixture 4, a lower base 5, a second FR4 fiberglass board 6, a polytetrafluoroethylene film 7, a first FR4 fiberglass board 8, a copper conductive frame 9, and a transverse cantilever 10. The fan with a rod 1 is made of plastic; the upper cover 2 and lower base 5 are milled from acrylic; the polytetrafluoroethylene film 7, the first FR4 fiberglass board 8, and the conductive frame 9 are stacked and bonded together in order from top to bottom to form the stator. The diameter of the first FR4 fiberglass board 8 is 132 mm, with a circular hole with a diameter of 10 mm in the center. The conductive frame 9 has the same dimensions as the first FR4 fiberglass board 8. The polytetrafluoroethylene films 7 are fan-shaped, with four sheets of polytetrafluoroethylene film 7 bonded to the first FR4 fiberglass board 8 in a circumferential direction at predetermined intervals. A number of regular fan-shaped oxygen-free copper sheets 3 are circumferentially bonded to a FR4 glass fiber board 6 with a diameter of 100 mm to form a rotor.

[0060] The bottom end of the stator is fixedly connected to the lower base plate 5, the top end of the stator is movably connected to the rotor, an upper cover plate 2 is arranged above the rotor, and the upper cover plate 2 and the lower base plate 5 are fixed with bolts and nuts as a fixing device 4. The main rod of the rod fan 1 passes through the upper cover plate 2, the rotor, the stator and the lower base plate 5 and is fixedly connected to the rotor. The front end of the horizontal arm 6 passes through the stator and contacts the rotor, and the end is fixedly connected to the bottom end of the stator.

[0061] Specifically, the FR4 glass fiber board 8 is provided with a plurality of holes equidistantly arranged in a circular direction near the center. The front end of the transverse cantilever 6 is bent and extended through the hole to contact the stator and the rotor. The end is bonded and fixed to the conductive frame 9. The transverse cantilever 6 is made of 65 manganese steel.

[0062] The basic principle of power source module A: When the oxygen-free copper sheet 3 (i.e., the "copper electrode") and the polytetrafluoroethylene film 7 (i.e., the "polytetrafluoroethylene electrode") come into contact, the two films with greatly different electronegativity rub against each other. When they separate, they will carry positive and negative charges of opposite polarity, forming a potential difference. (The back electrodes of these two materials will be connected through a load, allowing electrons to flow between the two electrodes under the action of the potential difference, thereby balancing the electrostatic potential difference between the films.) When the two contact surfaces overlap again, the potential difference generated by the frictional charges disappears, and the electrons will flow in the opposite direction. The two films continuously contact and separate, and the output end of the friction generator will output a cross-transition current pulse signal, thereby realizing the external output of electrical energy.

[0063] The rectifier circuit module B consists of a rectifier-converter module B1, a rectifier-step-down module B2, and a rectifier-feedback module B3. The rectifier-converter module B1 converts the 150V AC generated by the power source module into 220V DC via a bridge rectifier circuit composed of four diodes, ensuring the normal operation of the subsequent circuits. The rectifier-step-down module B2, through the interconnection of an AP3022 chip, diodes, an inductor, and a transformer, steps down the 220V DC to 24V DC, meeting the operating voltage of the NCP3063 chip in the circuit driver module, which has an operating range of 3-40V. The rectifier-feedback module B3, through the interconnection of resistors, capacitors, inductors, and diodes, forms a feedback circuit that stabilizes the operating state of the step-down module B2 and prevents interference from other factors.

[0064] The circuit driver module C, comprised of a chip voltage regulator module C1, an LED lamp structure module C2, and a transistor threshold module C3, steps down the input chip voltage to the LED lamp's operating voltage, enabling adaptive regulation of the LED's brightness and color as the voltage increases. The chip voltage regulator module C1, interconnected with the NCP3063 chip, a 2.2nF capacitor, 2.4kΩ and 3.9kΩ resistors, and a 47uH inductor, steps down voltages below 24V to below 15V and stabilizes voltages above 24V to between 15V and 18V, providing the adaptive voltage for the LED lamp structure module C2.

[0065] The LED lamp structure module C2 is composed of multiple LED lamp arrays. The rated voltage of each LED lamp is 2.5V and the rated current is 20mA. Each column is composed of six LED lamps connected in series. There are five columns in total. The colors of the five columns of LED lamps are red, green, blue, green, and blue respectively. The shape and color of the LED lamp can be changed according to actual needs.

[0066] The transistor threshold module C3 realizes the switching function by connecting the transistor to a 1000 ohm resistor. As the voltage continues to increase, when the conduction threshold of the transistor is reached, the transistors in each column are turned on, and the six LED lights in each column light up, and eventually all the LED lights are fully illuminated.

[0067] The rectifier circuit module B is electrically connected to the power storage module D. When the driving speed exceeds a certain range, the power exceeds a threshold, and the power storage module D stores the excess power. When the current is lower and the LED light needs to be turned on, the power storage module D can discharge the power to turn on the LED light.

[0068] Specifically, the present invention designs three FR4 glass fiber boards with different hole arrangements: the hole spacing of the 08-A board is 36°, and the size is 7mm*5mm; the hole spacing of the 08-B board is 30°, and the size is 6mm*4mm; the hole spacing of the 08-C board is 22.5°, and the size is 4mm*3mm.

[0069] Correspondingly, the transverse cantilever 10 is designed with different structures and sizes. 10-A has a single semicircular bend, 10-B has two connected semicircular bends, and 10-C has a trapezoidal bend. Their thickness a is uniformly 0.5mm, and their bend height d is uniformly 2.1mm. Their total length b and bend length c are determined by the dimensions of the aforementioned plates. For the 08-A plate, the dimensions are (b*c=) 21mm*7mm, with a width of 5mm; for the 08-B plate, 15mm*6mm, with a width of 4mm; and for the 08-C plate, 10mm*4mm, with a width of 3mm.

[0070] This design has been proven to be feasible after experiments, simulations and tests. Figure 15 As shown in the figure, when the rotor speed is 200 rpm, the maximum voltage reaches 200 V; when the rotor speed is 250 rpm, the maximum voltage reaches 225 V; when the rotor speed is 300 rpm, the maximum voltage reaches 250 V; when the rotor speed is 350 rpm, the maximum voltage reaches 275 V; and when the rotor speed is 400 rpm, the maximum voltage reaches 300 V. Through experiments, it is found that after rectification and voltage reduction, the LED lamp can achieve adaptive brightness changes.

[0071] Example 2

[0072] The manufacturing process of the generator set of the adaptive automobile ambient light system includes the following steps:

[0073] Step D1: Use epoxy glue to sequentially adhere four fan-shaped polytetrafluoroethylene films 7 and a copper conductive frame 9 to a 132 mm diameter FR4 fiberglass board 8. Allow to stand for 30 minutes. Then, place the front end of the transverse cantilever 10 into the rectangular hole reserved in the fiberglass board 8 and secure the end to the bottom of the copper conductive frame 9 with epoxy glue to prepare the stator.

[0074] Step D2, fixing the manufactured stator to the lower base plate 5;

[0075] Step D3: Obtain three regular fan-shaped oxygen-free copper sheets by laser cutting. Use epoxy glue to glue eight fan-shaped thin copper sheets 3 to a 100 mm diameter FR4 fiberglass board 26 at intervals. Let it stand for 30 minutes to produce a rotor.

[0076] Step D4, placing the rotor on top of the stator;

[0077] Step D5: Place the upper cover plate 2 above the rotor at a predetermined distance and securely connect it to the lower base plate 5 using bolts and nuts as a fixing device 4;

[0078] Step D6: insert the main rod of the rod fan 1 into the reserved hole in the center of the upper cover plate 2, the rotor, the stator and the lower base plate 5, and use epoxy glue to bond and fix the main rod of the rod fan 1 to the rotor component.

[0079] The preparation process of the transverse spiral arm is as follows:

[0080] S1 cutting: cutting the manganese steel plate into block-shaped cuboids;

[0081] S2 Bending: Bend one end of the manganese steel and use pliers to bend it from the bend to form it into a trapezoid or semicircular arc;

[0082] S3 primary electroplating: Place the bent part of the manganese steel into a cyanide-free zinc plating solution and pass a DC power supply to coat the surface of the manganese steel with a layer of zinc.

[0083] S4 secondary electroplating: Place the bent part of the galvanized manganese steel into a copper sulfate solution, pass a DC power supply, and attach a layer of copper to the surface of the zinc layer;

[0084] S5 Preparation of nanopile: In a heated state, put zinc-coated copper-coated manganese steel into concentrated sulfuric acid at a temperature of 180°C, react for 10 seconds, take out the manganese steel, and a finished lateral cantilever with surface-grown nanocones, nanowires or micropore structures will be obtained.

[0085] The inherent AC positive and negative pulse output characteristics of the four different modes of triboelectric devices currently developed, namely contact separation, relative sliding, single electrode, and independent, greatly limit their practical applications, mainly limiting the application of sensors and drivers for direct current. The triboelectric power generation device of the present invention uses a periodic precious metal (copper, silver, gold) lateral cantilever structure, optimizes the spacing arrangement, the number and size of periodic lateral cantilevers, and the nanocones, nanowires, and microvoid structures coated on the surface of the lateral cantilever, thereby controlling the conversion of mechanical friction energy into electrical energy in the thin film triboelectric device, improving the internal conversion efficiency of the triboelectric device, and greatly simplifying and optimizing the overall circuit module.

[0086] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of the present invention. Other modifications or equivalent substitutions made to the technical solutions of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
