Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to automotive sun visors, sun visor assemblies, and vehicles. Background Technology

[0002] With the development of vehicle intelligence, vehicles often need to display information and provide basic interaction to people outside the vehicle in scenarios such as parking, low-speed driving, or waiting for a shuttle. Existing technologies mainly employ the following solutions to achieve visual display and interaction on the vehicle's exterior: First, external independent display modules, which involve installing a display screen or indicator component separately on the outer or inner surface of the vehicle body. This type of solution typically requires additional mounting locations, openings, wiring harnesses, and brackets, as well as impact resistance and safety design, resulting in high system costs and complex vehicle integration. Furthermore, exposed components are susceptible to bumps or vandalism, leading to high maintenance costs and affecting the vehicle's appearance. Second, imaging solutions based on vehicle windows / windshields, which utilize the windshield or side windows for image projection or active display. This type of solution has strict requirements for optical transmittance, reflectivity, and haze control, and high compatibility with substrates, films, and optomechanical modules. It requires significant hardware investment and software development, and mass production feasibility and subsequent maintenance costs become limiting factors.

[0003] Therefore, how to provide a display path with sufficient visibility and interactivity for people outside the vehicle while minimizing changes to the vehicle body structure, reusing existing parts, and balancing low cost, ease of integration, and ease of maintenance has become a focus of industry attention. Integrating display functions into the vehicle's sun visor is considered one of the more feasible approaches: the sun visor is located near the upper edge of the windshield, has sufficient installation space and flip-up kinematic features, can provide an outward viewing window when people are near the front of the vehicle, and requires minimal modification to the overall vehicle body, making it easy to retrofit or implement on existing vehicle platforms.

[0004] However, existing technologies present thermal management challenges when integrating display functions into sun visors. This makes it difficult to dissipate the heat generated when the display components emit light, exacerbating heat accumulation within the cavity and affecting the lifespan of the display components and the user experience of the sun visor. Therefore, there is a need for a way to establish efficient heat dissipation for the display components in the sun visor. Utility Model Content

[0036] In related technologies, the car sun visor is an important interior component of a car. It is rotatably mounted on the top of the car's cab to provide sun protection, and a vanity mirror is also installed on the sun visor.

[0037] With the development of technology and the improvement of people's living standards, car sun visors are equipped with light-emitting components that can display text or patterns for communication with people outside the vehicle. However, these light-emitting components generate heat during operation, and the flat design of the sun visor results in poor heat dissipation.

[0038] In related technologies, the methods for heat dissipation of light-emitting components are relatively simple, usually employing a combination of heat sinks and fans. This results in poor heat dissipation, easily leading to overheating of the light-emitting components and causing damage. Therefore, this application provides an automotive sun visor, a sun visor assembly, and a vehicle to solve or improve the problem of poor heat dissipation of light-emitting components in sun visors.

[0039] The following is combined Figures 1 to 3 This describes an embodiment of the present application.

[0040] According to embodiments of this application, such as Figure 1 As shown, on one hand, a vehicle sun visor is provided, including: a support frame 1, a display component 2, and a lens 3. The support frame 1 constitutes the supporting body of the sun visor. The support frame 1 is made of a thermally conductive material. The support frame 1 has a first surface 101 and a second surface 102 arranged opposite to each other. The display component 2 is mounted on the first surface 101 of the support frame 1. The lens 3 is mounted on the second surface 102 of the support frame 1. The display component 2 is thermally connected to the supporting frame 1, or the display component 2 is thermally connected to the lens 3. The thermal connection described in this application is a heat transfer connection between the two components achieved through a mechanical thermally conductive structure or a thermally conductive medium.

[0041] In this embodiment, such as Figure 1 As shown, the supporting frame 1 uses a thermally conductive medium, which improves the heat dissipation effect on the display component 2. The display component 2 is disposed on the first surface 101 of the supporting frame 1. The heat of the display component 2 can be transferred to the supporting frame 1 for heat dissipation. At the same time, the display component 2 can also transfer heat to the lens 3 for heat dissipation. Transferring heat to the lens 3 increases the heat dissipation area and improves the heat dissipation effect. The lens 3 functions as a makeup mirror and also has the functions of heat conduction and heat dissipation, further improving the heat dissipation effect of the display component 2. The first surface refers to the side of the sun visor facing the windshield when it is unfolded, or the side of the sun visor facing the car seat when it is retracted, or the side of the sun visor opposite to the side where the lens is mounted.

[0042] The lens 3 conducts heat and dissipates heat, breaking through the limitation of the traditional lens 3 only serving as an optical element. The lens 3 and the supporting frame 106 form a heat-conducting connection structure, improving the heat conduction effect.

[0043] Specifically, the material of the supporting skeleton 1 can also be a thermally conductive epoxy resin-based composite material, a thermally conductive BMI (bismaleimide) composite material, a long fiber reinforced polypropylene material, or a graphene reinforced composite material.

[0044] In one embodiment, such as Figure 1 As shown, the supporting frame 1 has a through hole 103, which has a first end located on the first surface 101 and a second end located on the second surface 102. The display component 2 covers the first end of the through hole 103, and the lens 3 covers the second end of the through hole 103. This heat dissipation method solves the technical problem of constructing an effective heat conduction path when integrating a display component into the sun visor for external vehicle interaction. By using a thermally conductive material to support the frame and the display component, a stable heat dissipation channel is formed through the thermally conductive connection between the frame and the frame or lens, reducing the display temperature rise, ensuring the stability of the sun visor's external display effect and the lifespan of the display component itself, and improving the overall reliability of the component.

[0045] In this embodiment, such as Figure 1 As shown, the through-hole 103 connects the first surface 101 and the second surface 102, and also connects the display component 2 and the lens 3. This allows the heat generated by the display component 2 to be transferred to the lens 3 through the through-hole 103, and the display component 2 dissipates heat through the lens 3, improving the heat dissipation effect. Through this method, it is possible to achieve opposing mounting and thermal coupling within a limited thickness, with the two ends of the through-hole covered by the display component and the lens respectively. This results in a compact structure, a short thermal path, and clear assembly positioning, facilitating the integration of dual-sided functions.

[0046] In one embodiment, such as Figure 1 As shown, the lens 3 is positioned opposite to the light-emitting side of the display component 2, and a first heat-conducting medium is provided between the back of the lens 3 and the non-light-emitting side of the display component 2. By providing a first heat-conducting medium between the back of the lens and the non-light-emitting side of the display component, a back-to-back heat dissipation channel is constructed, reducing the risk of hot spots and warping on the back side of the display.

[0047] In this embodiment, such as Figure 1 As shown, the display component 2 and the lens 3 are respectively sealed at both ends of the through hole 103 to form a closed space. The first heat-conducting medium is filled in the closed space to realize the fixed connection between the back of the display component 2 and the back of the lens 3, and to improve the heat conduction effect between the display component 2 and the lens 3.

[0048] Specifically, the first heat-conducting medium uses high thermal conductivity silicone, with a thermal conductivity greater than or equal to 2.0 W / (m²). K), with a temperature range of -40 degrees Celsius to 120 degrees Celsius, is able to adapt to extreme environments outside the vehicle.

[0049] In one embodiment, such as Figure 1As shown, the first surface 101 of the support frame 1 is provided with a first mounting position 104, the second surface 102 of the support frame 1 is provided with a second mounting position 105, and the through hole 103 connects the first mounting position 104 and the second mounting position 105. The display component 2 is installed in the first mounting position 104, and the lens 3 is installed in the second mounting position 105; The space between the lens 3 and the bottom side and / or sidewall of the second mounting position 105 is filled with a second heat-conducting medium. And / or, the space between the display component 2 and the bottom side and / or sidewall of the first mounting position 104 is filled with a third thermally conductive medium.

[0050] In this embodiment, the display component 2 is installed in the first mounting position 104. The bottom and sidewalls of the display component 2 and the first mounting position 104 are filled with a third thermally conductive material, which increases the connection area between the display component 2 and the first mounting position 104, improves the heat conduction effect, and also improves the stability of the display component 2 mounted on the support frame 1. The lens 3 is installed in the second mounting position 105. The bottom and sidewalls of the lens 3 and the second mounting position 105 are filled with a second thermally conductive material, which improves the stability of the lens 3 mounted on the support frame 1. Furthermore, the second mounting position 105 increases the contact area with the lens 3, improving the heat dissipation effect.

[0051] Specifically, the sunshade also includes a decorative surface, which is attached to the load-bearing frame 1. The load-bearing frame can be made of a mixture of ABS (thermoplastic plastic, full name is acrylonitrile-butadiene-styrene copolymer) and glass fiber, which has high strength and good thermal conductivity.

[0052] In one embodiment, a heat-conducting plate is provided on the edge of the lens 3, the heat-conducting plate extends in a direction away from the lens 3, and the heat-conducting plate is connected to the supporting frame 1 through a heat-conducting element.

[0053] These features address the challenges of improving the assembly precision and thermal conductivity reliability of the display components and lenses. Cavity mounting is achieved through through-holes at the first / second mounting positions, and a second / third thermally conductive medium is filled between the lens / display component and its respective mounting position, enhancing fit, thermal conductivity, and reducing thermal resistance.

[0054] In this embodiment, the heat-conducting plate extends beyond the second mounting position 105 and contacts the second surface 102 of the support frame 1. The heat on the lens 3 can be transferred to the support frame 1 through the heat-conducting plate. In other words, the heat is transferred to the support frame 1. The heat-conducting component is connected to the support frame 1, and the heat-conducting component can further improve the heat conduction effect.

[0055] Specifically, the thickness of the lens 3 is 2mm to 3mm, preferably 3mm, and the width of the heat-conducting plate extending from the lens 3 is 5mm to 8mm, preferably 6mm.

[0056] Specifically, the heat-conducting components are aluminum alloy connectors such as screws or bolts.

[0057] The above features solve the technical problems of heat accumulation and insufficient heat diffusion in the lens edge area. By setting a heat-conducting plate at the lens edge and connecting it to the supporting frame, the heat at the lens edge is guided to the frame, thereby increasing the heat dissipation area and making the lens more uniform in temperature.

[0058] In one embodiment, the heat-conducting plate is provided with multiple heat dissipation fins.

[0059] In this embodiment, heat is transferred from the heat-conducting plate to the heat dissipation fins, and multiple heat dissipation fins can accelerate the transfer of heat from the heat-conducting plate to the air.

[0060] Specifically, the height of the heat dissipation fins is 3mm to 5mm, specifically, the height of the heat dissipation fins can be set to 3mm, 4mm or 5mm, and the number of heat dissipation fins is 5 to 8, specifically, the number of heat dissipation fins can be set to five, six or seven or eight. The heat dissipation fins are exposed to the outside of the supporting frame 1, thereby improving the heat dissipation effect by increasing the contact area with the air.

[0061] In one embodiment, such as Figure 2 and Figure 3 As shown, a lens cover is also provided, which is movably connected to the supporting frame 1. The movable connection can be a sliding connection, a rotating connection, or other connection methods that allow the lens surface to be exposed or covered, and is suitable for switching between the closed and open positions of the lens 3. In the closed position, there is a heat dissipation gap between the lens cover and the lens 3. When the lens cover is closed, it is easy to cause stuffiness and heat accumulation, which will affect the display and the life of the lens. By leaving a heat dissipation gap between the lens cover and the lens, a convection channel is still maintained in the closed state, which can reduce the temperature rise inside the cavity and avoid condensation and increased glare reflection.

[0062] In this embodiment, when the mirror cover is in the open position, the lens 3 can be used as a makeup mirror. When the mirror cover is in the closed position, it can protect the lens 3. A heat dissipation gap is provided between the mirror cover and the lens 3. When the vehicle moves, airflow can be formed around the mirror cover. The airflow passes through the heat dissipation gap and carries away the heat on the lens 3.

[0063] Specifically, the mirror cover and the supporting frame 1 can be either rotatably connected or slidably connected.

[0064] Specifically, the size of the heat dissipation gap is 0.3mm to 0.5mm, preferably 0.3mm, 0.4mm, or 0.5mm.

[0065] Specifically, lens 3 is a sapphire lens or thermally conductive glass.

[0066] In one embodiment, such as Figure 1 As shown, a third mounting position is provided on the bottom side of the first mounting position 104, and a through hole 103 is provided on the bottom side of the third mounting position. The display component 2 includes an electrically connected light-emitting screen 201 and a circuit board 202. The circuit board 202 is installed in a third mounting position, the light-emitting screen 201 is installed in a first mounting position 104, a third heat-conducting medium is provided between the light-emitting screen 201 and the bottom side and / or side wall of the first mounting position 104, and a fourth heat-conducting medium is provided between the circuit board 202 and the lens 3.

[0067] In this embodiment, the back side of the light-emitting screen 201 is connected to the first mounting position 104 via a second thermally conductive medium. The coating thickness of the second thermally conductive medium is 0.5mm to 1mm, specifically, it can be 0.5mm, 0.7mm, or 1mm. Furthermore, there are no air bubbles remaining between the back side of the light-emitting screen 201 and the second mounting position 105.

[0068] In some embodiments, a fourth thermally conductive medium is provided on the circuit board 202, and the fourth thermally conductive medium connects the circuit board 202 to the lens 3.

[0069] It should be noted that the heat generated by the light-emitting screen 201 is transferred to the second heat-conducting medium through its back. The second heat-conducting medium then transfers the heat to the supporting frame 1. Airflow carries away the heat from the supporting frame 1, thus dissipating heat from the light-emitting screen 201. Specifically, the airflow during vehicle movement assists in dissipating heat to the external environment. The heat on the circuit board 202 is transferred to the lens 3 through the fourth heat-conducting medium for heat dissipation.

[0070] It should be noted that the first mounting position, the second mounting position, and the third mounting position are all mounting slots.

[0071] These features solve the technical problems of installing the light-emitting screen and optimizing the heat dissipation path, thereby improving the overall thermal management and maintenance convenience of the machine.

[0072] In one embodiment, a thermally conductive and light-transmitting sheet is further included, the thermally conductive and light-transmitting sheet being provided with a plurality of protrusions; The light-emitting screen 201 includes a support plate and multiple light sources. Specifically, the support plate is connected to the first surface 101, and the heat-conducting and light-transmitting sheet is connected to the support plate. The multiple light sources are disposed on the support plate, and the multiple light sources are connected to the multiple protrusions through a fifth heat-conducting medium.

[0073] In this embodiment, multiple light sources are arranged in an array on the support plate, which can be a matrix arrangement or a ring array arrangement. The support plate is in contact with the supporting frame 1. Specifically, the light sources are LED lamp beads, and a heat-conducting and light-transmitting sheet covers the multiple light sources. The heat generated by the light sources is transferred to the heat-conducting and light-transmitting sheet through a fifth heat-conducting medium and multiple protrusions. The heat-conducting and light-transmitting sheet transfers the heat to the supporting frame 1, and the supporting frame 1 conducts the heat to the external environment.

[0074] It should be noted that setting multiple protrusions can increase the heat transfer efficiency of the fifth heat-conducting medium, and at the same time improve the stability of the contact between the heat-conducting light-transmitting sheet and the light source.

[0075] In some embodiments, multiple light sources are arranged in a matrix, and the multiple light sources are controlled by circuit board 202 to form a display screen capable of displaying patterns. The display screen is 380mm long, 110mm wide, and has a resolution of Pitch 1.5 of 25373 (the device can distinguish 25373 independent points within each 1.5 unit length interval). Pitch refers to the pitch (the center distance between two adjacent, identical points (such as the center point of a pixel or a scribe line), which is a core parameter describing the density of points or lines). The operating voltage of the light sources is 12V, and the operating current is 3A.

[0076] Specifically, the height of the protrusion is 0.3mm to 0.5mm, preferably 0.3mm, 0.4mm, or 0.5mm. The distance between two adjacent protrusions is 1mm to 2mm, preferably 1mm, 1.5mm, or 2mm. The protrusions are in direct contact with the light source through a fifth heat-conducting medium, reducing the heat conduction path and improving heat conduction efficiency.

[0077] In some embodiments, the first, second, third, fourth, and fifth thermally conductive media can all be replaced with thermally conductive pads. The thickness of the thermally conductive pads is 1 mm to 2 mm, preferably 1 mm, 1.5 mm, or 2 mm, and the thermal conductivity of the thermally conductive pads is greater than or equal to 2.5 W / (m²). K) Thermal pads are suitable for situations where the gap between two contacting parts is uneven, such as when the gap between the back of the support plate and the first mounting position 104 is uneven. Placing the thermal pad in the middle improves the fit and thermal stability.

[0078] In some embodiments, the back of the light-emitting screen 201 conducts heat to the support frame 1 through the lens 3, and the front of the light-emitting screen 201 conducts heat to the support frame 1 through the heat-conducting light-transmitting sheet, forming a "double-sided heat dissipation path" to further improve heat dissipation efficiency and ensure that the temperature of electronic components on the circuit board 202 can still be controlled below 50 degrees Celsius in extreme high-temperature environments (such as 85 degrees Celsius outside the vehicle).

[0079] The material of the thermally conductive and light-transmitting sheet can be sapphire lens or thermally conductive glass, with the thermal conductivity of the glass being greater than or equal to 15 W / (m²). K), with a light transmittance of ≥92%, can balance optical performance and heat dissipation performance.

[0080] In one embodiment, the thermally conductive and light-transmitting sheet is connected to the light-emitting side of the display component 2, which can protect the light-emitting side. This can shorten the thermal path, improve light transmission, and enhance surface temperature uniformity.

[0081] In one embodiment, the thermally conductive and light-transmitting sheet has a connecting surface with multiple protrusions. These protrusions contact the light-emitting side of the display component 2 via a sixth thermally conductive medium. This enables efficient multi-point heat conduction and stress buffering, reducing interface thermal resistance and improving reliability.

[0082] Specifically, the first, second, third, fourth, and fifth thermally conductive media can all be selected from high thermal conductivity gels with a thermal conductivity greater than or equal to 3.0 W / (m²). K).

[0083] In one embodiment, such as Figure 1 As shown, it also includes a light-transmitting outer cover 4, which covers the outside of the supporting frame 1 and covers the display component 2. The light-transmitting outer cover 4 is used to transmit the light emitted by the display component 2 out of the sunshade.

[0084] In some embodiments, a thermally conductive and light-transmitting sheet is disposed between the light source and the light-transmitting outer cover 4. The connecting surface of the thermally conductive and light-transmitting sheet is in contact with the light source through a fifth thermally conductive medium, the thermal conductivity of which is greater than or equal to 1.5 W / (m²). K), the edge of the heat-conducting and light-transmitting sheet is in contact with the first surface 101 of the supporting frame 1, and the heat-conducting and light-transmitting sheet is fixed to the supporting frame 1 by screws or bolts, the screws or bolts being made of aluminum alloy.

[0085] Specifically, the heat-conducting and light-transmitting sheet and the light-transmitting outer cover 4 can be designed as an integrated unit. The light-transmitting outer cover 4 and the heat-conducting and light-transmitting sheet are combined through injection molding to reduce assembly gaps. At the same time, the heat-conducting and light-transmitting sheet is connected to the load-bearing frame 1 through buckles, simplifying the disassembly and assembly process and facilitating later maintenance.

[0086] Specifically, part of the light-transmitting outer cover 4 covers the light-emitting screen 201, and part of it is sealed and connected to the first surface 101 of the light-shielding plate body.

[0087] The specific light-transmitting outer cover 4 is a membrane structure, and the specific material is PC (polycarbonate), a thermoplastic polymer with extremely excellent performance. Simply put, it can be imagined as a kind of "transparent metal," possessing strength close to that of metal, transparency like glass, and also being very tough. The light transmittance of the light-transmitting outer cover 4 is greater than or equal to 90%, which can ensure the display effect of the light-emitting screen 201. The edge of the light-transmitting outer cover 4 is seamlessly connected to the supporting frame 1, forming a closed display area, and the light-emitting screen 201 is set within the display area.

[0088] In one embodiment, the light-transmitting outer cover 4 is attached to the outer surface of the display component 2, or the gap between the light-transmitting outer cover 4 and the outer surface of the display component 2 is less than or equal to 3.0 mm. This can improve optical clarity and facilitate heat conduction / convection.

[0089] In one embodiment, the light-transmitting outer covering 4 is a light-transmitting sheet made of thermoplastic composite material, and the light-transmitting outer covering 4 is a flexible sheet and / or the body of the light-transmitting sheet is a colored sheet. The flexible sheet is easy to process and easy to wrap around the outside of the supporting frame 1. Using a flexible sheet can accommodate frame deformation and assembly tolerances, facilitates assembly, reduces stress concentration, and improves durability. The color of the colored sheet can be configured to match or be consistent with the color of the vehicle's interior, thereby improving the overall aesthetics of the sun visor and the consistency of the vehicle's interior appearance.

[0090] Thermoplastic composite materials possess specific optical absorption and scattering properties, along with good toughness and resilience. Their molecular structure interacts with specific wavelengths within the visible light spectrum. For light emitted by display components, the molecular structure of thermoplastic composite materials can generate specific interactions with these wavelength ranges. Within the visible light range, light-transmitting sheets made of thermoplastic composite materials have a low absorption coefficient for the main emission wavelengths of display components, allowing most light to pass through the material smoothly, thus achieving high light transmittance and meeting the light transmission requirements of display components. Since the pore size of the light-transmitting sheet is not directly observable by the human eye, it can shield the supporting frame, related electronic components, and non-emitting display components behind it, achieving both good shielding and decorative effects. Furthermore, the uniform pore distribution of light-transmitting sheets made of thermoplastic composite materials ensures clear and distortion-free display of video images generated by display components such as screens.

[0091] Specifically, the thermoplastic composite material is TPC material.

[0092] As an alternative implementation, the light-transmitting outer covering 4 can also be a light-transmitting sheet made of polycarbonate material.

[0093] As an alternative implementation, the light-transmitting outer covering 4 can also be a light-transmitting sheet made of acrylic (PMMA).

[0101] In some embodiments, the light-transmitting outer covering 4 includes a single-layer structure or a multi-layer structure; the multi-layer structure of the light-transmitting outer covering 4 is an adhesive structure formed by bonding. The multi-layer structure of the light-transmitting outer covering 4, being an adhesive structure formed by bonding, can reduce stress concentration through continuous surface connections during the bonding process, maintain the original strength of the adhesive structure, and improve the fatigue life of the adhesive structure.

[0102] Different vehicle models have different requirements for hardness, stain resistance, appearance, and texture. Various layered structures can be selected to meet different design goals.

[0106] In some embodiments, the light-transmitting outer cover 4 contains light-diffusing particles. The light-diffusing particles form numerous tiny scattering centers in the light-transmitting outer cover 4. When light enters the light-transmitting outer cover 4, these scattering centers scatter the light, thereby changing the direction of light propagation and allowing the light to disperse evenly in all directions.

[0107] In some embodiments, there are multiple light-diffusing particles, which are uniformly dispersed in the light-transmitting outer cover 4, thereby improving vehicle visibility.

[0108] In some embodiments, the light-transmitting outer cover 4 is a heat-pressed laminated part formed by heat pressing.

[0109] In some embodiments, the light-transmitting outer cover 4 is a vacuum thermoforming laminated part formed by vacuum thermoforming bonding.

[0110] In some embodiments, the light-transmitting outer covering 4 is a roll-pressed bonding part formed by roll pressing.

[0111] In some embodiments, the light-transmitting outer covering 4 is a flexible sheet. Flexible sheets are easier to process and wrap around the outside of the load-bearing frame 1. Using a flexible sheet allows it to accommodate the deformation and assembly tolerances of the load-bearing frame 1, facilitating assembly while reducing stress concentration and improving durability.

[0112] In some embodiments, the vehicle sun visor further includes a transparent adhesive layer, through which the light-transmitting outer cover 4 is bonded to the outside of the supporting frame 1 and the display component 2. The transparent adhesive layer not only secures the light-transmitting outer cover 4 to the supporting frame 1 and the display component 2, but also enhances the light transmission performance of the light-transmitting outer cover 4 by selecting an adhesive material with a matching refractive index.

[0113] In some embodiments, the light-transmitting outer cover 4 has a conforming area, which is correspondingly disposed to the display component 2 and is attached to the outer surface of the display component 2. The conforming area is attached to the outer surface of the display component 2 to avoid the appearance of structures such as bubbles at the display component 2, which would affect the light transmission effect and surface aesthetics.

[0114] In some embodiments, the thickness of the light-transmitting outer cover 4 in the conformal area differs from its thickness at other locations outside the conformal area. This difference in thickness allows for adaptation to different location requirements, providing better light transmission and protection, optimizing regional performance, and reducing overall weight.

[0115] In some embodiments, under different working condition design objectives, the light-transmitting outer cover 4 may also have a gap between it and the display component 2, the thickness of which is less than or equal to 3.0 mm. By setting the gap, and the thickness of the gap being less than or equal to 3.0 mm, a light-guiding space can be provided between the display component 2 and the light-transmitting outer cover 4, ensuring that the light can be propagated uniformly, and also avoiding the problem of the outer cover overheating due to long-term use.

Optimizing the microstructure of the light-transmitting outer cover 4 achieves uniform pore distribution, avoiding "bright spots" and "dark areas" caused by uneven light scattering, and ensuring overall image consistency. Improving the optical stability of the light-transmitting outer cover 4 reduces wavelength obstruction and absorption of the LED light source, ensuring balanced transmission of the three primary colors of RGB light, and solving the distortion problems of image color shift and edge blurring. Through in-depth research and optimization design of the compatibility between the material of the light-transmitting outer cover 4 and the LED light source, the obstruction of the LED light source by the light-transmitting outer cover 4 is minimized, ensuring that the video image generated by the RGB LED beads can pass through the light-transmitting outer cover 4 completely and accurately. Whether it is the detail of the image, the accuracy of the color, or the saturation, it can be effectively guaranteed, so that the surface image can be displayed clearly and without distortion. At the same time, it also takes into account the shielding function of the light-transmitting outer cover 4, effectively hiding the supporting frame 1 and the electronic components behind it (such as circuit boards, connectors, etc.), and avoiding the exposure of the internal structure and affecting the aesthetic appearance of the product.
