Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a vehicle sun visor, a sun visor assembly, and a vehicle. Background Technology

[0002] With the development of vehicle intelligence, vehicles often need to display and interact with people outside the vehicle in scenarios such as parking, low-speed driving, or waiting for pick-up. Current technologies mainly offer the following solutions for achieving visual display and interaction on the vehicle's exterior: One is an external, independent display module, where a display screen or indicator component is installed 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. Another solution is based on window / windshield imaging: projecting or actively displaying images using the windshield or side windows. This type of solution requires strict requirements in terms of optical transmittance, reflectivity, and haze control, and demands high compatibility with substrates, films, and optomechanical modules. In addition, the high cost of use, large hardware investment, and significant software development requirements limit mass production feasibility and after-sales maintenance costs.

[0003] In summary, existing solutions for displaying information and providing basic interaction on the exterior of vehicles generally suffer from problems such as numerous new components, significant structural modifications, high costs, complex reliability and regulatory verification, and high modification difficulty. Especially in existing vehicle models or low-to-medium cost platforms, there remains a lack of solutions that balance engineering feasibility and economy, aiming to provide sufficient visibility and interactivity for people outside the vehicle while minimizing changes to the vehicle structure, reusing existing components, and ensuring low cost, ease of integration, and ease of maintenance. Therefore, it is necessary to propose a technical solution that can reuse existing vehicle components, enable external information display / interaction even when people are outside the vehicle, and minimize vehicle modifications, maintain controllable costs, and offer good reliability and maintainability, thereby addressing the aforementioned shortcomings of existing technologies in external display and interaction.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0042] According to an embodiment of the present invention, a vehicle sun visor is provided, comprising a supporting frame 1, a light-emitting component 2, and a light-transmitting outer cover 3; the light-emitting component 2 is disposed on a first side of the supporting frame 1, which is the side facing the windshield when the sun visor is unfolded, or the side facing the vehicle seat when the sun visor is retracted, or the side of the sun visor opposite to the mounting lens; the light-transmitting outer cover 3 covers the outside of the supporting frame 1 and covers the light-emitting component 2, and the light-transmitting outer cover 3 is used to transmit the light emitted by the light-emitting component 2 to the outside of the sun visor.

[0043] The light-emitting component 2 is mounted on the supporting frame 1. It can interact with passengers and drivers inside the vehicle, and can also interact with pedestrians outside the vehicle after the sun visor is rotated. The supporting frame 1 and the light-emitting component 2 are covered with a light-transmitting outer cover 3. The light-transmitting outer cover 3 can ensure that the content displayed in the light-emitting component 2 can be smoothly seen to the outside of the sun visor, realizing information interaction and information display between the sun visor and pedestrians, drivers and passengers. At the same time, the light-transmitting outer cover 3 can shield and protect the light-emitting component 2, preventing the light-emitting component 2 from being exposed and damaged.

[0044] In summary, by placing the light-emitting components on the first side of the supporting frame and covering them with a light-transmitting outer cover, the light emitted from the sun visor can be transmitted to the outside of the sun visor when it is unfolded and facing the windshield. This achieves the goal of providing visual interactive information to people outside the vehicle without altering the vehicle body components and windshield structure. At the same time, when the vehicle is folded up, the components are not exposed and the exterior shape and body structure are not changed. Furthermore, the vehicle installation requires minimal modification and the increase in wiring harnesses and brackets is limited, which is conducive to mass production.

[0045] In one embodiment, the light-transmitting outer covering 3 is a light-transmitting sheet made of thermoplastic composite material.

[0046] Thermoplastic composite materials possess specific optical absorption and scattering characteristics, along with good toughness and resilience. Their molecular structure interacts with specific wavelengths within the visible light band. For the light emitted by the light-emitting component 2, the molecular structure of the thermoplastic composite material can generate specific interactions with these wavelength ranges. Within the visible light range, the translucent sheet made of thermoplastic composite material has a low absorption coefficient for the main emission wavelength of the light-emitting component 2, allowing most light to pass through the material smoothly, thus achieving high light transmittance and meeting the light transmission requirements of the light-emitting component 2. Since the dimensions of the supporting frame 1 and some electronic components are larger than the pore size of the translucent sheet, the pore size of the translucent sheet cannot be directly observed by the human eye. Therefore, the translucent sheet can shield the supporting frame, related electronic components, and non-emitting display components behind it. The supporting frame 1 and electronic components cannot pass through these pores, and the light reflected or scattered by the light-emitting component 2 is blocked by the translucent sheet made of thermoplastic composite material, preventing it from being seen by the observer through the translucent outer cover. This achieves good shielding and decorative properties, realizing the shielding effect. Furthermore, the light-transmitting sheet made of thermoplastic composite material has a uniform pore distribution, which enables the video images generated by the light-emitting components such as the display screen to be displayed clearly without distortion.

[0047] In a specific implementation, the thermoplastic composite material is TPC material.

[0048] As an alternative implementation, the light-transmitting outer covering 3 may be a light-transmitting sheet made of polycarbonate (PC) material.

[0049] As an alternative implementation, the light-transmitting outer covering 3 may be a light-transmitting sheet made of acrylic (PMMA).

[0050] As an alternative implementation, the light-transmitting outer covering 3 may be a light-transmitting sheet made of thermoplastic polyurethane (TPU).

[0062] In one embodiment, the light-transmitting outer covering 3 is a single-layer structure or a multi-layer structure; the multi-layer structure of the light-transmitting outer covering 3 is an adhesive structure formed by bonding.

[0063] The multi-layer structure of the light-transmitting outer covering 3 is an adhesive structure formed by bonding. During the bonding process, continuous surface connections can reduce stress concentration, maintain the original strength of the adhesive structure, and improve the fatigue life of the adhesive structure.

[0064] Different vehicle models have different requirements for hardness, stain resistance, appearance, and texture. Various layered structures can be selected to meet different design goals.

[0065] In one embodiment, the thermoplastic-based composite material comprises one or more of thermoplastic polyurethane, thermoplastic polyester elastomer, copolyester, cyclic olefin polymer, cyclic olefin copolymer, styrene-based thermoplastic elastomer, and soft polyvinyl chloride; the multilayer structure of the light-transmitting outer covering 3 includes at least two identical or different layers selected from the thermoplastic polyurethane layer, thermoplastic polyester elastomer layer, copolyester layer, cyclic olefin polymer layer, cyclic olefin copolymer layer, styrene-based thermoplastic elastomer layer, and soft polyvinyl chloride layer.

[0074] In one embodiment, the thickness of the light-transmitting outer covering 3 is 0.3 mm to 0.7 mm.

[0075] The thickness of the light-transmitting outer covering 3 is 0.3mm to 0.7mm, which can not only have better light transmittance, but also better shielding ability and mechanical strength.

[0076] In a specific embodiment, the thickness of the light-transmitting outer cover 3 is 0.3 mm, or the thickness of the light-transmitting outer cover 3 is 0.7 mm, or the thickness of the light-transmitting outer cover 3 is 0.5 mm.

[0077] In one embodiment, the light-transmitting outer covering 3 contains light-diffusing microparticles.

[0078] The light-diffusing particles form numerous tiny scattering centers in the light-transmitting outer cover 3. When light enters the light-transmitting outer cover 3, these scattering centers will scatter the light, thereby changing the direction of light propagation and allowing the light to disperse evenly in all directions.

[0079] In a further embodiment, there are multiple light-diffusing particles, which are uniformly dispersed in the light-transmitting outer cover 3, thereby improving the visibility of the vehicle exterior.

[0080] In one embodiment, the light-transmitting outer covering 3 is a flexible sheet.

[0081] Flexible sheets are easier to process and wrap around the outside of the load-bearing frame 1. Using flexible sheets can accommodate frame deformation and assembly tolerances, making assembly easier, while also reducing stress concentration and improving durability.

[0082] In one embodiment, the vehicle sun visor further includes a transparent adhesive layer, through which the light-transmitting outer cover 3 is bonded to the outside of the supporting frame 1 and the light-emitting component 2.

[0083] The transparent adhesive layer can not only fix the light-transmitting outer cover 3 to the supporting frame 1 and the light-emitting component 2, but also improve the light transmission performance of the light-transmitting outer cover 3 by selecting a refractive index matching adhesive.

[0084] In one embodiment, the light-transmitting outer cover 3 has a conforming area, which is correspondingly disposed to the light-emitting component 2 and is attached to the outer surface of the light-emitting component 2.

[0085] The conformal area is attached to the outer surface of the light-emitting component 2, which can avoid the formation of structures such as bubbles at the light-emitting component 2, thus avoiding affecting the light transmission effect and surface aesthetics.

[0086] In one embodiment, the thickness of the light-transmitting outer covering 3 in the conformal region is different from its thickness at other locations outside the conformal region.

[0087] The light-emitting component 2 and the supporting frame 1 have different requirements for the light transmission performance and mechanical strength of the light-transmitting outer cover 3. Therefore, the thickness of the light-transmitting outer cover 3 in the conformal area is different from the thickness in other positions outside the conformal area. This can adapt to the needs of different positions, have better light transmission and protection effects, optimize regional performance, and reduce the overall weight.

[0088] In one embodiment, the light-transmitting outer cover 3 is a single flexible sheet. After the light-transmitting outer cover 3 covers the outside of the supporting frame 1, the edge of the light-transmitting outer cover 3 is joined at the edge of the supporting frame 1.

[0089] The light-transmitting outer cover 3 is a single flexible sheet material, which can not leave splicing gaps on the surface when it is wrapped around the outside of the supporting frame 1, and can also hide the joint gaps at the edges of the supporting frame 1, thus ensuring the aesthetic effect of the overall appearance.

[0090] In one embodiment, the outer periphery of the light-transmitting outer cover 3 is pressed against the edge of the supporting frame 1.

[0091] The outer periphery of the light-transmitting outer cover 3 is pressed against the edge of the supporting frame 1 to ensure the bonding effect between the light-transmitting outer cover 3 and the supporting frame 1 and to prevent the light-transmitting outer cover 3 from curling up.

[0092] In one embodiment, the vehicle sun visor further includes a pressure frame, and the outer periphery of the light-transmitting outer cover 3 is sealed and pressed against the edge of the supporting frame 1 by the pressure frame.

[0093] By setting the frame, the bonding effect between the light-transmitting outer cover 3 and the supporting frame 1 can be guaranteed, preventing the light-transmitting outer cover 3 from curling up, and a sealing effect can also be achieved.

[0094] In one embodiment, the vehicle sun visor further includes a flexible sealing strip, which is annular in structure and disposed between the outer periphery of the light-transmitting outer cover 3 and the supporting frame 1.

[0095] The flexible sealing strip can easily adapt to the shape of the supporting frame 1 and can seal the vehicle sun visor in the circumferential direction; in addition, the flexible sealing strip is set between the outer periphery of the light-transmitting outer cover 3 and the supporting frame 1 to achieve overall sealing.

[0096] In one embodiment, under different working condition design objectives, the light-transmitting outer cover 3 may also have a gap between it and the light-emitting component 2, and the thickness of the gap is less than or equal to 3.0 mm.

[0097] By setting the gap, and ensuring that the gap thickness is less than or equal to 3.0 mm, a light-guiding space can be provided between the light-emitting component 2 and the light-transmitting outer cover 3, ensuring that the light can be propagated evenly, and also avoiding the problem of the outer cover heating up due to long-term use.

[0098] It should be noted that the connection and positional relationship between the light-transmitting outer cover and the display component or the supporting frame of this application can be achieved by the above-mentioned adhesive bonding, or by bonding through external force, or by setting a gap of less than or equal to 3.0 mm, or by combining the above three methods.

[0099] In one embodiment, the vehicle sun visor further includes an annular spacer ring, which surrounds the outer periphery of the light-emitting component 2, is disposed on the supporting frame 1, and contacts the light-transmitting outer cover 3, and the height of the annular spacer ring is consistent with the thickness of the gap.

[0100] By setting an annular spacer, a gap can be formed between the light-transmitting outer cover 3 and the light-emitting component 2, so that a light-guiding space is formed between the light-emitting component 2 and the light-transmitting outer cover 3, ensuring that the light can be propagated evenly; at the same time, the setting of the annular spacer can also prevent the light from propagating to the outside of the annular spacer.

[0101] In one embodiment, the support frame 1 has a mounting part 11 on its first side, and the light-emitting component 2 is connected to the mounting part 11.

[0102] The mounting part 11 allows for better positioning and fixation of the light-emitting component 2.

[0103] In one embodiment, the outer periphery of the mounting portion 11 is provided with an annular stepped support surface, and the stepped support surface is coplanar with the light-emitting surface of the light-emitting component 2 facing the light-transmitting outer cover 3.

[0104] The stepped support surface allows the light-emitting surfaces of the supporting frame 1 and the light-emitting component 2 to be coplanar, thereby making the overall outer surface of the light-transmitting outer cover 3 form a relatively smooth surface.

[0105] In one embodiment, the supporting frame 1 is further provided with a circumferential light-shielding wall, which surrounds the outer periphery of the mounting portion 11.

[0106] The circumferential light-shielding wall can prevent light from spreading to the outer periphery of the circumferential light-shielding wall, thus ensuring the light-emitting effect of the light-emitting component 2.

[0107] In one embodiment, the mounting portion 11 is a mounting base or mounting frame, and the light-emitting component 2 is fixed in the mounting portion 11 by the mounting base or the mounting frame.

[0108] The installation position enhances the stability of the light-emitting component 2 within the mounting portion 11. The installation method achieves positioning and engagement via positioning posts and / or positioning slots, and is secured by snap-fit ​​devices and / or fasteners.

[0109] In one embodiment, the support frame 1 is provided with a wiring groove, which connects the mounting part 11 and the edge of the support frame 1.

[0110] The wiring channel connects the mounting part 11 and the edge of the supporting frame 1, and the connecting wire of the light-emitting component 2 can be led out to the outside of the supporting frame 1 through the wiring channel.

[0111] In one embodiment, a pivoting mechanism 4 is provided on one side of the load-bearing frame 1, and the load-bearing frame 1 is used to be hinged to the vehicle via the pivoting mechanism 4.

[0112] The supporting frame 1 is hinged to the vehicle via a pivoting mechanism 4, so that the angle of the vehicle sun visor can be adjusted according to the user's needs inside the vehicle, or the sun visor can be extended to a specific position by electric drive in a specific scenario.

[0113] In one embodiment, the light-emitting component 2 is provided with a light-emitting surface, and the supporting frame 1 is provided with a heat dissipation structure in the adjacent area of ​​the mounting part 11. The heat dissipation structure is one or a combination of at least two of the following: a heat conduction channel, a heat sink, a heat conduction adhesive, and a heat conduction pad, and is thermally connected to the supporting frame. The adjacent area of ​​the mounting part can be the side of the mounting part facing the display component, the side of the mounting part facing away from the display component, or one side of the annular area around the mounting part.

[0114] By setting up a heat dissipation structure, the heat generated by the light-emitting component 2 can be dissipated from the side away from the light-emitting surface through the heat dissipation structure, and the light-emitting surface position can also be guaranteed to have a good display effect.

[0115] In one embodiment, the light-emitting component 2 is a display screen.

[0116] The display screen can be used to show corresponding text and images to users inside the vehicle and pedestrians outside the vehicle.

[0117] In a further embodiment, the light-emitting component 2 can be an RGB LED, OLED, LCD, or other light-emitting display device. The light-transmitting outer cover 3 is a light-transmitting sheet made of thermoplastic composite material, which can improve the light transmittance of the light-transmitting outer cover 3. Without increasing the power of the RGB LED, it ensures that the RGB LED light source can pass through efficiently to meet the display brightness requirements, while reducing energy consumption and glare risk. Optimizing the microstructure of the light-transmitting outer cover 3 achieves uniform pore distribution, avoiding the "bright spots" and "dark areas" problems caused by uneven light scattering, and ensuring overall image consistency. Improving the optical stability of the light-transmitting outer cover 3 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 3 and the LED light source, the obstruction of the LED light source by the light-transmitting outer cover 3 is minimized, ensuring that the video image generated by the RGB LED beads can pass through the light-transmitting outer cover 3 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 3, effectively hiding the supporting frame 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.

[0118] In one embodiment, the vehicle sun visor further includes a heat dissipation structure disposed between the display screen and the supporting frame 1.

[0119] By designing a heat dissipation structure, the display screen can be guaranteed to have good heat dissipation performance, avoiding heat dissipation difficulties caused by the display screen being covered in the light-transmitting outer cover 3, and preventing damage to the display screen due to poor heat dissipation.

[0120] In one embodiment, the vehicle sun visor further includes a heat dissipation medium disposed between the display screen and the supporting frame 1, and the heat dissipation medium is a thermally conductive adhesive or a thermally conductive pad.

[0121] The heat dissipation medium can enable the display screen to have a better heat dissipation effect, avoid the display screen from having difficulty dissipating heat due to being covered in the light-transmitting outer cover 3, prevent the display screen from being damaged due to poor heat dissipation, and can also fix and bond the display screen to the supporting frame 1.

[0122] In one embodiment, the long side of the display screen is aligned with the long side of the supporting frame 1.

[0123] The long side of the display screen is aligned with the long side of the supporting frame 1, which provides sufficient space for the display screen to be installed, while ensuring that the display screen has a good display effect on the supporting frame 1 and has an aesthetically pleasing appearance.

[0124] In one embodiment, the vehicle sun visor further includes a transparent cover plate disposed between the display screen and the light-transmitting outer cover 3, and pressed and adhered to the light-transmitting outer cover 3.

[0125] The transparent cover provides good protection for the display screen and also has a good light guiding effect.

[0126] In one embodiment, the light-transmitting outer covering body is a colored sheet, preferably a non-transparent colored sheet, and the color of the colored sheet can be configured to be the same as or match the color of the vehicle interior, thereby improving the overall aesthetics of the sun visor and the consistency of the vehicle's interior appearance.

[0127] According to an embodiment of the present invention, another aspect provides a sun visor assembly, including the two vehicle sun visors described above, a control circuit board, and a wiring harness. The control circuit board is disposed between the two vehicle sun visors, and the vehicle sun visors are connected to the control circuit board via the wiring harness.

[0128] By placing the control circuit board in the middle, the length of the wiring harness, interfaces, and control devices can be further reduced, which is beneficial to the overall vehicle layout. At the same time, it can support the linkage display or zone control of the sun visors on both sides, further improving interactivity.

[0129] According to an embodiment of the present invention, another aspect provides a vehicle including the aforementioned vehicle sun visor.

[0130] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
