Description

Technical Field

[0001] This utility model relates to the field of automotive lighting, specifically a defogging and defrosting device for automotive lighting. Background Technology

[0002] Automotive lights are systems used for illumination and signaling in vehicles. They can be categorized by function and location into external lighting, internal lighting, and signal lights, ensuring driving safety and the visual transmission of vehicle status. Automotive lights not only meet basic lighting needs but also convey critical driving information through color, position, and flashing patterns, forming an important component of the vehicle safety system.

[0003] Currently, most traditional automotive lights rely on natural ventilation or passive heating to defrost. Some solutions use a single heating wire, which can easily lead to localized overheating or incomplete defrosting, resulting in low efficiency, high energy consumption, and uneven temperature distribution. Therefore, this paper proposes an automotive light defrosting and defogging device. Utility Model Content

[0009] As a further improvement of this utility model: the shell module is equipped with an intelligent control module and a convection module.

[0010] As a further embodiment of this utility model: the convection module includes a miniature centrifugal fan, the outer surface of which is fixedly connected to a gas circulation pipe that penetrates the main body of the lamp, and the outer surface of which is fixedly connected to an air outlet pipe that penetrates the housing module.

[0011] As a further improvement of this utility model: the lamp body is provided with a temperature and humidity sensor inside, and the outer surface of the lamp body is fixedly connected with a gas and water discharge channel.

[0012] As a further improvement of this utility model: the outer surface of the housing module is provided with a connection port, and a waterproof coating is fixedly connected to the outer surface of the housing module.

[0013] Compared with existing technologies, the beneficial effects of this utility model include: the device uses a PTC ceramic heater in conjunction with an electric heating film layer for dual heating, and a micro fan for hot air circulation, which can clear fog within five minutes and quickly defrost in rainy or snowy weather. It can effectively solve the problems of slow defogging and poor effect of traditional car lights that rely on natural ventilation or simple electric heating wires. At the same time, the PTC ceramic heater can automatically adjust the temperature and will not overheat, saving more than 30% of electricity compared with traditional heating, making it more cost-effective in the long run.

[0021] According to one embodiment of the present invention, in conjunction with the accompanying drawings, Figure 1-4 .

[0022] A defogging and defrosting device for automotive lamps includes a lamp body 1, a light source 10 fixedly connected to the inner bottom wall of the lamp body 1, and a heating component 8 inside the lamp body 1. The heating component 8 includes an electrothermal film layer 802, the outer surface of which is fixedly connected to the inner side wall of the lamp body 1. A PTC ceramic heater 801 is fixedly embedded in the edge of the lamp body 1. The lamp body 1 integrates the light beam and provides a good heating space with good sealing performance. The heating component 8 quickly heats the environment inside the lamp body 1, effectively defogging and defrosting. The PTC ceramic heater 801 is made of barium titanate-based ceramic and can automatically maintain a constant temperature, effectively preventing overheating and extending the service life of the equipment. The electrothermal film layer 802 is made of graphene or metal alloy film, which can provide uniform heating and has a large coverage area, effectively adhering to the inner wall of the lamp body 1 and increasing the heating area.

[0023] In this embodiment, a base 7 is fixedly connected to the outer surface of the lamp body 1. A connecting component 2 is provided on the outer surface of the base 7. The connecting component 2 includes a locking block 202. A slot 201 is opened on the outer surface of the base 7. The size of the slot 201 is adapted to the locking block 202. A force-bearing block 203 is fixedly connected to the outer surface of the locking block 202. The side of the force-bearing block 203 away from the locking block 202 is fixedly connected to the outer surface of the housing module 4. The connecting base 7 provides a good installation position for the connecting component 2. The locking block 202 and the slot 201 cooperate to allow the equipment to be quickly disassembled without tools, which is convenient for staff to maintain the equipment. The force-bearing block 203 can provide good support for the housing module 4 and improve the stability of the housing module 4.

[0024] In this embodiment, a housing module 4 is fixedly connected to the outer surface of the connecting component 2. An intelligent control module 3 is located inside the housing module 4, and a convection module 6 is also located inside the housing module 4. The convection module 6 includes a miniature centrifugal fan 602. A gas circulation pipe 601 penetrating the lamp body 1 is fixedly connected to the outer surface of the miniature centrifugal fan 602. An air outlet pipe 603 penetrating the housing module 4 is fixedly connected to the outer surface of the miniature centrifugal fan 602. A temperature and humidity sensor 9 is located inside the lamp body 1. A gas and water discharge channel 11 is fixedly connected to the outer surface of the lamp body 1. A connection port 5 is located on the outer surface of the housing module 4. A waterproof coating is fixedly connected to the outer surface of the housing module 4. Through the intelligent control module 3, the entire device can be monitored and controlled in real time. Simultaneously, the temperature and humidity sensor 9 is embedded... The device is inserted into the inner wall of the lamp body 1 and connected to the intelligent control module 3 via a signal line. This allows for real-time monitoring of the internal environment of the lamp body 1, enabling the intelligent control module 3 to precisely regulate the temperature inside the device. Through the convection module 6, a micro centrifugal fan 602 connects to the gas circulation pipe 601 that runs through the lamp body 1 and the air outlet pipe 603 that extends to the outside of the housing module 4. This effectively reduces noise and achieves efficient airflow circulation. The air and water discharge channel 11 is installed at an angle at the bottom of the device, leading to the outside of the vehicle body. The one-way valve design effectively prevents water backflow. The waterproof coating effectively improves the device's hydrophobicity and extends its service life. The connection port 5 allows for easy connection to the vehicle's main control system.

[0025] The working principle of this utility model is as follows: When the temperature and humidity sensor 9 detects that the humidity inside the lamp body 1 is too high or that frost has formed, the intelligent control module 3 will start the PTC ceramic heater 801 and the electric heating film layer 802 in the heating component 8 to heat the lamp evenly. At the same time, the micro centrifugal fan 602 will blow hot air to the inner wall of the lamp cover through the gas circulation pipe 601 to accelerate the evaporation of fog. The condensate produced will be discharged through the gas and water discharge channel 11. Furthermore, the quick disassembly and assembly design of the card block 202 and the card slot 201 will facilitate maintenance by the staff. Finally, the waterproof coating will prevent the intrusion of external water vapor, enabling the equipment to achieve efficient and energy-saving defogging and defrosting.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
