Description

Technical Field

[0001] The utility model relates to the technical field of instrument panels, and in particular discloses a nano waterproof vehicle instrument panel. Background Art

[0002] In the modern automotive industry, the instrument panel, as a crucial component, not only displays vehicle operating status information such as speed, fuel level, and water temperature, but also serves as a crucial interface for driver interaction. However, traditional instrument panels often overlook the importance of waterproofing in their designs. This is especially true in inclement weather conditions, such as rain or driving through water. The control panel inside the instrument panel is susceptible to water penetration, leading to circuit shorts and component damage, which in turn affects the instrument panel's accuracy and stability, and even poses a threat to driving safety. To improve the waterproofing of instrument panels, some control panels with simple waterproofing treatments have emerged on the market. However, these products typically only apply a simple waterproofing treatment to the surface of the control panel and fail to fundamentally address the problem of water penetration. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a nano-waterproof vehicle instrument panel.

[0004] To achieve the above-mentioned objectives, the utility model provides a nano-waterproof vehicle instrument panel, including a control panel, which includes a printed circuit board, a microcontroller unit arranged on the printed circuit board, a power module, a communication module, and an alarm module. The control panel is also provided with a protective film layer, which is plated and coated on the control panel to prevent the control panel from being damaged by short circuit caused by external moisture. The user conveys the control command to the communication module through an external control component, and the communication module transmits the control command to the microcontroller unit. The microcontroller unit converts the external command into corresponding data and displays it on the instrument panel to provide the user with vehicle operation status information.

[0005] By setting up a control board including a printed circuit board, a microcontroller unit, a power module, a communication module and an alarm module, and coating it with a protective film layer that can effectively prevent water molecules from penetrating, the stable operation of the instrument panel in humid environments is ensured. At the same time, users can easily send instructions to the instrument panel through external control components and obtain real-time vehicle operating status information, thereby improving driving safety and convenience.

[0006] The protective film layer comprises a nano-waterproof layer applied to the outside of the control panel. This protective film is applied to the control panel via electroplating, vacuum plating, or vapor deposition. Electroplating involves applying an electric current through an electrolyte to deposit metal ions onto the control panel surface, forming a thin film. This method creates a uniform, dense coating that provides excellent corrosion protection, wear resistance, and decorative effects. Vacuum plating (also known as vacuum coating or vacuum electroplating) is a coating process performed under vacuum conditions. It utilizes the principles of physical vapor deposition (PVD) to heat the coating material until it evaporates or sputters, then deposits it onto the control panel surface under the influence of an electric or magnetic field. Vacuum coating forms high-quality films with excellent adhesion and gloss, while maintaining the original properties of the coating material. Finally, deposition methods include a variety of physical and chemical methods, such as chemical vapor deposition (CVD) and physical vapor deposition (PVD). PVD deposits the coating material onto the control panel surface through a physical process at low temperatures, forming a film with excellent wear and corrosion resistance.

[0007] The nano waterproof layer includes sodium methylsiliconate, polytetrafluoroethylene or methyl silicate. Sodium methylsiliconate is a small molecule water-soluble mixture that can generate methylsiloxane under the action of carbon dioxide and water in the air, forming a water-insoluble methylsilyl ether (i.e., a waterproof film) with good waterproof performance. When applied to the nano waterproof layer, it can effectively block the capillary pores of the control panel, enhance the compactness, and thus improve the anti-seepage ability. Polytetrafluoroethylene is a polymer material with extremely low surface energy. Its surface energy is extremely low, making it difficult for water molecules to stay and penetrate on its surface. Therefore, when applied to the nano waterproof layer, it can significantly improve the waterproof performance of the instrument panel. Methyl silicate has good hydrophobic properties and can form a dense waterproof layer that effectively prevents the penetration of water molecules. At the same time, methyl silicate also has excellent weather resistance and corrosion resistance, and can maintain the stability of waterproof performance for a long time. In practical applications, the appropriate nano waterproof layer material can be selected according to the specific needs and working environment of the instrument panel to ensure the waterproof performance and durability of the instrument panel. At the same time, the selection of these materials also reflects the diversity and flexibility of the design of automotive instrument panel protective film layers.

[0008] The thickness of the nano waterproof layer is 0.1-100 μm. This design of a nano waterproof layer thickness of 0.1-100 μm provides the control panel with a thin, flexible, and excellent waterproof performance. This thickness range of the nano waterproof layer also makes its preparation process more controllable and stable.

[0009] The vehicle instrument panel also includes a shell, a display screen mounted on the shell, a button assembly and a lighting assembly. The control panel is mounted in the shell. Multiple groups of mounting holes are provided on the shell. The button assembly and the lighting assembly are mounted on the mounting holes of the shell via fasteners. The display screen, button assembly and lighting assembly are all electrically connected to the control panel.

[0010] The housing includes an upper shell and a lower shell, and the instrument panel body also includes a sealing waterproof ring, which is disposed on the upper shell and connected to the lower shell via the sealing waterproof ring. The provision of the sealing waterproof ring can further effectively prevent moisture from penetrating into the instrument panel through the gaps in the housing, thereby protecting the internal electronic components and circuits and preventing short circuits or damage caused by moisture.

[0011] The lower shell is provided with a cylindrical boss on the side away from the upper shell, and a shock-isolating pad is installed in the cylindrical boss. The combination of the cylindrical boss and the shock-isolating pad allows the instrument panel to be more firmly mounted on the vehicle, reducing shaking caused by driving actions such as bumps or turns, and improving stability and safety during driving.

[0012] The lower shell is provided with a plurality of heat dissipation holes, and the instrument panel can dissipate heat through the heat dissipation holes to maintain a stable temperature after long-term use.

[0013] The protective film layer further comprises a high hardness layer arranged outside the nano waterproof layer, a polymer film layer arranged outside the high hardness layer, and a polymer hydrophilic material layer arranged outside the polymer film layer.

[0014] By integrating a nano-waterproof layer, a high-hardness layer, a polymer film layer, and a polymer hydrophilic material layer, the control panel's waterproof performance, durability, and scratch resistance are significantly improved. At the same time, the overall strength and wear resistance are enhanced, effectively keeping the internal components of the instrument panel dry and clean, thereby extending the service life of the instrument panel and providing the driver with a safer, more reliable, and more comfortable driving experience.

[0015] The high-hardness layer has a thickness of 0.1-100 μm and is positioned outside the nano-waterproof layer to enhance the durability and scratch resistance of the control panel. The polymer film layer has a thickness of 0.1-100 μm and is used to improve the overall strength and wear resistance of the protective film layer. The polymer hydrophilic material layer can have a thickness of 0.1-50 μm. The polymer hydrophilic material layer covers the outermost surface of the nano-waterproof layer to accelerate the shedding of water droplets remaining on the control panel, preventing moisture accumulation on the control panel surface, thereby keeping the control panel surface dry and clean. The thickness design of the high-hardness layer, polymer film layer, and polymer hydrophilic material layer respectively enhances the durability, scratch resistance, overall strength, wear resistance, and ability to maintain a dry and clean surface of the vehicle instrument panel, ensuring stable operation of the instrument panel in harsh environments.

[0016] Beneficial effects of the present invention: The vehicle instrument panel of the present invention adopts a multi-layer protective film design, the core of which is to coat the control panel with a nano-waterproof layer by electroplating, vacuum plating or deposition. The nano-waterproof layer is made of materials such as sodium methylsiliconate, polytetrafluoroethylene or methyl silicate. These materials have good waterproof, weather-resistant and corrosion-resistant properties, and can effectively prevent water molecules from penetrating into the interior of the control panel, protecting it from damage. At the same time, a protective film layer of a high-hardness layer, a polymer film layer and a polymer hydrophilic material layer is added on the basis of the nano-waterproof layer. The high-hardness layer, the polymer film layer and the polymer hydrophilic material layer respectively enhance the durability, anti-scratch ability, overall strength and wear resistance of the control panel, as well as the ability to keep the surface dry and clean, providing the driver with a safer, more reliable and comfortable driving experience in bad weather.

[0023] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0024] See also Figures 1 to 4As shown, the utility model is a nano-waterproof vehicle instrument panel, including a control panel 1, which includes a printed circuit board 2, a micro control unit 3 arranged on the printed circuit board 2, a power module 4, a communication module 5, and an alarm module 6. The control panel 1 is also provided with a protective film layer 7, which is plated and coated on the control panel 1. The protective film layer 7 prevents the control panel 1 from being damaged by a short circuit caused by external moisture; the user conveys the control command to the communication module 5 through an external control component, and the communication module 5 transmits the control command to the micro control unit 3. The micro control unit 3 converts the external command into corresponding data and displays it on the instrument panel to provide the user with vehicle operation status information.

[0025] By providing a control board 1 including a printed circuit board 2, a micro control unit 3, a power module 4, a communication module 5 and an alarm module 6, and coating it with a protective film layer 7 that can effectively prevent the penetration of water molecules, the stable operation of the instrument panel in a humid environment is ensured. At the same time, the user can easily send instructions to the instrument panel through an external control component and obtain vehicle operation status information in real time, thereby improving driving safety and convenience.

[0026] The protective film layer 7 includes a nano-waterproof layer 8 disposed on the outside of the control board 1. The protective film layer 7 is applied to the control board 1 via electroplating, vacuum plating, or vapor deposition. Electroplating involves applying an electric current to an electrolyte solution, causing metal ions to deposit onto the surface of the control board 1 to form a thin film. This method produces a uniform, dense coating that provides excellent corrosion protection, wear resistance, and decorative effects. Vacuum plating (also known as vacuum coating or vacuum electroplating) is a coating process performed under vacuum conditions. It utilizes the principles of physical vapor deposition (PVD) to heat the coating material to an evaporating or sputtering state, then deposit it onto the surface of the control board 1 under the influence of an electric or magnetic field. Vacuum coating can form high-quality films with excellent adhesion and gloss, while maintaining the original properties of the coating material. Finally, deposition methods include a variety of physical and chemical methods, such as chemical vapor deposition (CVD) and physical vapor deposition (PVD). PVD deposits the coating material onto the surface of the control board 1 through a physical process at low temperatures, forming a film with excellent wear and corrosion resistance.

[0027] The nano waterproof layer 8 includes sodium methyl siliconate, polytetrafluoroethylene or methyl silicate. Sodium methyl siliconate is a small molecule water-soluble mixture that can generate methylsiloxane under the action of carbon dioxide and water in the air, forming a water-insoluble methylsilyl ether (i.e., a waterproof film) with good waterproof performance. When applied to the nano waterproof layer 8, it can effectively block the capillary pores of the control panel 1, enhance the compactness, and thus improve the anti-seepage ability. Polytetrafluoroethylene is a polymer material with extremely low surface energy. Its surface energy is extremely low, making it difficult for water molecules to stay and penetrate on its surface. Therefore, when applied to the nano waterproof layer 8, the waterproof performance of the instrument panel can be significantly improved. Methyl silicate has good hydrophobic properties and can form a dense waterproof layer to effectively prevent the penetration of water molecules. At the same time, methyl silicate also has excellent weather resistance and corrosion resistance, and can maintain the stability of waterproof performance for a long time. In actual application, the appropriate nano waterproof layer 8 material can be selected according to the specific needs and working environment of the instrument panel to ensure the waterproof performance and durability of the instrument panel. At the same time, the selection of these materials also reflects the diversity and flexibility of the design of the vehicle instrument panel protective film layer 7.

[0028] The thickness of the nano waterproof layer 8 is 0.1-100 μm. The design of the nano waterproof layer 8 with a thickness of 0.1-100 μm provides the control panel 1 with a light, flexible, and excellent waterproof performance. This thickness range of the nano waterproof layer 8 also makes its preparation process more controllable and stable.

[0029] The vehicle instrument panel also includes a shell 13, a display screen 14 mounted on the shell 13, a button assembly 15 and a light assembly 16. The control panel 1 is mounted in the shell 13. The shell 13 has multiple groups of mounting holes. The button assembly 15 and the light assembly 16 are mounted on the mounting holes of the shell 13 via fasteners. The display screen 14, button assembly 15 and light assembly 16 are all electrically connected to the control panel 1.

[0030] The housing 13 includes an upper shell 17 and a lower shell 18. The instrument panel body also includes a sealing waterproof ring, which is disposed on the upper shell 17 and connected to the lower shell 18 via the sealing waterproof ring. The provision of the sealing waterproof ring can further effectively prevent moisture from penetrating into the instrument panel through the gaps in the housing 13, thereby protecting the internal electronic components and circuits and preventing short circuits or damage caused by moisture.

[0031] The lower shell 18 is provided with a cylindrical boss 19 on the side away from the upper shell 17, and a shock-isolating pad is installed in the cylindrical boss 19. The combination of the cylindrical boss 19 and the shock-isolating pad allows the instrument panel to be more firmly mounted on the vehicle, reducing shaking caused by driving actions such as bumps or turns, and improving stability and safety during driving.

[0032] The lower shell 18 is provided with a plurality of heat dissipation holes 21 , and the instrument panel can dissipate heat through the heat dissipation holes 21 to maintain a stable temperature after long-term use.

[0033] The protective film layer 7 further includes a high hardness layer 9 arranged outside the nano waterproof layer 8 , a polymer film layer 11 arranged outside the high hardness layer 9 , and a polymer hydrophilic material layer 12 arranged outside the polymer film layer 11 .

[0034] By integrating the nano-waterproof layer 8, the high-hardness layer 9, the polymer film layer 11 and the polymer hydrophilic material layer 12, the waterproof performance, durability and scratch resistance of the control panel 1 are significantly improved, while the overall strength and wear resistance are enhanced, effectively keeping the internal components of the instrument panel dry and clean, thereby extending the service life of the instrument panel and providing the driver with a safer, more reliable and comfortable driving experience.

[0035] The high-hardness layer 9 has a thickness of 0.1-100 μm and is positioned outside the nano-waterproof layer 8 to enhance the durability and scratch resistance of the control panel 1. The polymer film layer 11 has a thickness of 0.1-100 μm and is used to improve the overall strength and wear resistance of the protective film layer 7. The polymer hydrophilic material layer 12 can have a thickness of 0.1-50 μm. The polymer hydrophilic material layer 12 covers the outermost surface of the nano-waterproof layer 8 and is used to accelerate the shedding of water droplets on the control panel 1, preventing moisture accumulation on the surface of the control panel 1, thereby keeping the surface of the control panel 1 dry and clean. The thickness design of the high-hardness layer 9, polymer film layer 11, and polymer hydrophilic material layer 12 respectively enhances the durability, scratch resistance, overall strength, wear resistance, and ability to maintain a dry and clean surface of the vehicle instrument panel 1, ensuring stable operation of the instrument panel in harsh environments.
