Description
Technical Field
[0001] This application relates to the field of vehicle sun visor technology, specifically to a sun visor component, a sun visor, a sun visor assembly, and a vehicle. Background Technology
[0002] A sun visor is an interior component installed above the windshield in the driver's compartment of a vehicle. Its primary function is to block direct sunlight, preventing glare for the driver and passengers, thereby improving driving safety and passenger comfort. To meet diverse user needs, sun visors often integrate a vanity mirror, allowing drivers and passengers to check their appearance while driving. Currently, traditional sun visors with vanity mirrors typically use a sliding or flip-up cover structure to prevent the mirror from reflecting light and disturbing occupants when not in use. However, this cover structure limits the size of the vanity mirror, preventing the maximization of the mirror area and affecting usability. Furthermore, the additional mechanical structure of this cover increases the overall weight of the sun visor. Utility Model Content
[0003] In view of this, this application provides a sunshade component, a sunshade panel, a sunshade assembly, and a vehicle to maximize the mirror area, improve ease of use, and reduce the overall weight of the sunshade.
[0004] The first aspect of this application provides a sunshade component, including a body and a dimming mirror. The dimming mirror includes a reflective glass and a dimming glass sequentially disposed on the body. The dimming glass is configured to transmit light when powered on and block light when powered off. The reflective glass is configured to reflect light when the dimming glass transmits light.
[0005] The aforementioned sunshade assembly, by incorporating a dimming mirror consisting of a reflective glass and a dimming glass, allows the dimming glass to be powered on when the makeup mirror function is needed. When powered on, the dimming glass allows light to pass through, and the light is reflected by the reflective glass, thus enabling the makeup mirror function. When the makeup mirror function is not needed, the dimming glass is de-powered, blocking light and preventing it from entering the reflective glass, thus disabling the makeup mirror function. The sunshade component of this application enables or disables the function of a makeup mirror by energizing or de-energizing the dimming glass. The dimming mirror replaces the traditional cover plate structure, achieving nearly 100% coverage relative to the main body, thus maximizing the mirror area of the sunshade component, improving ease of use, and making the structure more concise and aesthetically pleasing. Furthermore, replacing the traditional cover plate structure with the dimming mirror reduces the overall weight and manufacturing cost of the sunshade component. By placing the dimming mirror on the main body, which then supports and protects it, the structural strength and service life of the sunshade component are improved.
[0006] In one embodiment, the dimming mirror further includes a light-transmitting substrate disposed on the side of the dimming glass opposite to the reflective glass.
[0007] Thus, by setting the aforementioned light-transmitting substrate to protect the dimming glass, it is beneficial to improve the service life of the dimming glass. At the same time, the light-transmitting substrate has good light transmittance, ensuring the mirror reflection effect of the dimming mirror.
[0008] In one embodiment, the dimming mirror further includes a first colloid and a second colloid, the first colloid being bonded between the reflective glass and the dimming glass, and the second colloid being bonded between the dimming glass and the light-transmitting substrate.
[0009] In this way, by setting the first and second colloids mentioned above, the glass pieces in the dimming mirror are tightly connected, thereby improving the stability of the dimming mirror.
[0010] In one embodiment, both the first colloid and the second colloid are non-acidic glass adhesives.
[0011] Thus, by limiting both the first and second colloids to non-acidic glass adhesives, the first and second colloids have high light transmittance and better environmental friendliness, while also being able to adapt to thermal expansion and contraction, ensuring the stable use of the dimmer.
[0012] In one embodiment, the reflective glass includes transparent glass and a reflective coating disposed on the side of the transparent glass facing the body.
[0013] Thus, by defining the reflective glass as including transparent glass and a reflective coating, the reflective glass can achieve the function of reflecting light, and the cost of reflective glass is low, which helps to reduce the manufacturing cost of sunshade components.
[0014] In one embodiment, the body includes a base and an extension, the extension being connected to the edge of the base and surrounding the dimming mirror.
[0015] In this way, by setting the main body including a base and an extension, the dimming mirror is assembled through the base and the extension, and the periphery of the dimming mirror is protected by the extension, while avoiding the risk of potential injury to the driver and passengers due to the exposure of the periphery of the dimming mirror.
[0016] In one embodiment, the dimming glass is one of polymer-dispersed liquid crystal glass, electrochromic glass, and suspended particle glass.
[0017] Thus, by limiting the dimming glass to one of polymer-dispersed liquid crystal glass, electrochromic glass, or suspended particle glass, the dimming glass can transmit light when powered on and block light when powered off.
[0018] A second aspect of this application provides a sunshade, including a sunshade component as described in the first aspect or any embodiment of the first aspect.
[0019] A third aspect of this application provides a sun visor assembly including a control system and a sun visor as described in the second aspect, the control system being coupled to the dimming glass and configured to energize or de-energize the dimming glass.
[0020] A fourth aspect of this application provides a vehicle including a sun visor assembly as described in the third aspect.
[0021] Furthermore, the technical effects brought about by the second, third, and fourth aspects can be found in the first aspect or any embodiment of the first aspect, and will not be repeated here. Attached Figure Description

Detailed Implementation
[0026] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Where there is no conflict, the different embodiments and features described below can be combined with each other.
[0027] A sun visor is an interior component installed above the windshield in the driver's compartment of a vehicle. Its primary function is to block direct sunlight, preventing glare for the driver and passengers, thereby improving driving safety and passenger comfort. To meet diverse user needs, sun visors often integrate a vanity mirror, allowing drivers and passengers to check their appearance while driving. Currently, traditional sun visors with vanity mirrors typically use a sliding or flip-up cover structure to prevent the mirror from reflecting light and disturbing occupants when not in use. However, this cover structure limits the size of the vanity mirror, preventing the maximization of the mirror area and affecting usability. Furthermore, the additional mechanical structure of this cover increases the overall weight of the sun visor.
[0028] Therefore, embodiments of this application propose a sunshade component, sunshade panel, sunshade panel assembly, and vehicle to maximize the mirror area, improve ease of use, and reduce the overall weight of the sunshade panel.
[0029] First, please refer to Figure 1 and Figure 2 The diagrams show a structural schematic and a cross-sectional schematic of the sunshade component 100 provided in the embodiments of this application.
[0030] The sunshade assembly 100 of this application embodiment is applied to the sun visor of a vehicle. It is understood that this application embodiment does not limit the type of vehicle; the vehicle can be a pure electric vehicle, a hybrid electric vehicle, a gasoline-powered vehicle, etc.
[0031] Specifically, the sunshade component 100 of this application embodiment includes a body 10 and a dimming mirror 20. The dimming mirror 20 includes a reflective glass 21 and a dimming glass 22 sequentially disposed on the body 10. The dimming glass 22 is configured to transmit light when powered on and block light when powered off. The reflective glass 21 is configured to reflect light when the dimming glass 22 transmits light to present a mirror effect.
[0032] Thus, the sunshade component 100 of this application embodiment, by setting the dimming mirror 20 including a reflective glass 21 and a dimming glass 22, when the makeup mirror function is needed, the dimming glass 22 is powered on, and after the dimming glass 22 is powered on, light is transmitted, and the light is reflected by the reflective glass 21 after passing through the dimming glass 22, and the sunshade component 100 realizes the makeup mirror function; when the makeup mirror function is not needed, the dimming glass 22 is de-powered, and after the dimming glass 22 is de-powered, the light transmittance decreases to block light and prevent light from entering the reflective glass 21, and the sunshade component 100 cancels the makeup mirror function. The sunshade component 100 of this application enables or disables the function of a makeup mirror by energizing or de-energizing the dimming glass 22. The dimming mirror 20 can replace the traditional cover plate structure, and the dimming mirror 20 can achieve a near 100% coverage rate relative to the body 10, increasing the mirror area on the sunshade component 100, thereby maximizing the mirror area of the sunshade component 100, improving ease of use, and making the structure of the sunshade component 100 simpler and more aesthetically pleasing. In addition, replacing the traditional cover plate structure with the dimming mirror 20 can reduce the overall weight of the sunshade component 100 and reduce the manufacturing cost of the sunshade component 100. By setting the dimming mirror 20 on the body 10, the body 10 plays a role in supporting and protecting the dimming mirror 20, which helps to improve the structural strength and service life of the sunshade component 100.
[0033] The embodiments of this application will be further described below with reference to the accompanying drawings.
[0034] In some embodiments, the body 10 includes a base 11 and an extension 12, the extension 12 being connected to the edge of the base 11 and surrounding the dimming mirror 20. The shape of the cross-section of the body 10 parallel to the dimming mirror 20 can be configured according to actual conditions, such as a rounded rectangle, a rounded trapezoid, a rounded rectangle with a notch, or a rounded trapezoid with a notch, etc., and this embodiment does not specifically limit this. It can be understood that the dimming mirror 20 can also be considered as being embedded in the body 10. Thus, by configuring the body 10 to include the base 11 and the extension 12, the dimming mirror 20 is assembled using the base 11 and the extension 12, and the extension 12 protects the periphery of the dimming mirror 20, preventing the periphery of the dimming mirror 20 from being exposed and posing a potential risk of injury to the driver and passengers, ensuring the stable use of the dimming mirror 20, and thus improving the service life of the dimming mirror 20.
[0035] Understandably, when the extension body 12 is removed from the main body 10, the size of the dimming mirror 20 can be close to that of the base body 11, thereby enabling the dimming mirror 20 to achieve a coverage of nearly 100%.
[0036] In some embodiments, the dimming mirror 20 further includes a light-transmitting substrate 23, which is disposed on the side of the dimming glass 22 opposite to the reflective glass 21. The light-transmitting substrate 23 can be a transparent glass, transparent plastic, or other object with high light transmittance. Thus, by providing the light-transmitting substrate 23, the dimming glass 22 is protected from damage, which helps to extend its service life. Simultaneously, the good light transmittance of the light-transmitting substrate 23 allows more light to pass through, which helps to ensure the specular reflection effect of the dimming mirror 20.
[0037] In some embodiments, the dimming mirror 20 further includes a first colloid 24 and a second colloid 25. The first colloid 24 is bonded between the reflective glass 21 and the dimming glass 22, and the second colloid 25 is bonded between the dimming glass 22 and the light-transmitting substrate 23. In this embodiment, both the first colloid 24 and the second colloid 25 are non-acidic glass adhesives. Thus, by providing the aforementioned first colloid 24 and second colloid 25, the glass components in the dimming mirror 20 are tightly connected, improving the stability of the dimming mirror 20. By limiting the first colloid 24 and the second colloid 25 to non-acidic glass adhesives, the first colloid 24 and the second colloid 25 have high light transmittance, are odorless, and are more environmentally friendly. They can also adapt to thermal expansion and contraction, ensuring the stable use of the dimming mirror 20.
[0038] It is understood that in other embodiments, the first colloid 24 and the second colloid 25 may also be other adhesives with high light transmittance, such as optical adhesives, etc., and this application embodiment does not specifically limit them.
[0039] In some embodiments, the reflective glass 21 includes a transparent glass 211 and a reflective coating 212, with the reflective coating 212 disposed on the side of the transparent glass 211 facing the body 10. The reflective glass 21 can be a floating glass, and the reflective coating 212 can be a metal film layer, such as a silver metal film layer, an aluminum metal film layer, or other highly reflective metal film layers. When applying the reflective coating 212, it can be deposited on the transparent glass 211 by chemical silver plating, vacuum evaporation of an aluminum film, or sputtering of an aluminum film. Thus, by defining the reflective glass 21 as including a transparent glass 211 and a reflective coating 212, the reflective glass 21 achieves the function of reflecting light, and the reflective glass 21 has a low cost, which helps to reduce the manufacturing cost of the sunshade assembly 100.
[0040] In some embodiments, the dimming glass 22 can be one of polymer-dispersed liquid crystal (PDLC) glass, electrochromic (EC) glass, or suspended particle device (SPD) glass. Specifically, in polymer-dispersed liquid crystal glass, liquid crystal droplets are dispersed in a polymer matrix. When energized, the liquid crystals are arranged in an ordered manner (transparent), and when de-energized, they scatter randomly (fogging, which can also be understood as blocking light). In electrochromic glass, the transmittance and color of the glass are changed by voltage-driven ion migration (such as tungsten oxide). In suspended particle glass, the suspended particles are oriented (transparent) or randomly distributed (blocking light) in an electric field. Further details are omitted here. In this embodiment, the dimming glass 22 can be polymer-dispersed liquid crystal glass. It is understood that in other embodiments, the dimming glass 22 can also be electrochromic glass or suspended particle glass. Thus, by limiting the dimming glass 22 to one of polymer-dispersed liquid crystal glass, electrochromic glass, or suspended particle glass, the dimming glass 22 can transmit light when powered on and block light when powered off.
[0041] This application embodiment also provides a sun shade (not shown in the figure). The sun shade includes the sun shading component 100 as described in the above embodiment. It is understood that the sun shade may also include other components, such as a pivot, a light source, etc., wherein the light source may be disposed on the extension 12 of the main body 10. For the sake of brevity, this embodiment will not provide examples and descriptions of each component. Thus, the technical effects of the sun shade in this embodiment can be referred to the technical effects brought about by any of the above embodiments, and will not be repeated here.
[0042] Please see Figure 3 This application also provides a sun visor assembly 1. The sun visor assembly 1 includes a control system 2000 and a sun visor 1000 as described in the above embodiments. The control system 2000 is coupled to a dimming glass 22 and is configured to energize or de-energize the dimming glass 22. It is understood that the control system 2000 may include wiring harnesses, control modes, etc., and the wiring harnesses are configured to be electrically connected between the control modes, the power supply, and the dimming glass 22. For the sake of brevity, this embodiment will not provide specific examples or descriptions. Therefore, the technical effects of the sun visor assembly 1 in this embodiment can be found in any of the above embodiments, and will not be repeated here.
[0043] For example, control modes may include, but are not limited to, physical switches, capacitive touch switches, virtual control switches, voice control switches, gesture control switches, etc.
[0044] The physical switch is triggered by a mechanical structure. The physical switch can be a push-button switch, toggle switch, rotary switch, slide switch, etc. The physical switch can be set on the body 10 of the sun visor 1000, the center console of the vehicle, or other locations.
[0045] The capacitive touch switch is triggered by human body capacitive touch of a preset area. The capacitive touch switch can be set on the body 10 of the sun visor 1000, the center console of the vehicle, or other locations.
[0046] The virtual control switch is triggered by a virtual button on the touch screen. The virtual control switch can be set on the vehicle's central control screen, mobile phone software, or other locations.
[0047] The voice control switch is triggered by receiving voice commands and can be set on the vehicle's center console, mobile phone software, or other locations.
[0048] Gesture control switches are triggered by receiving gesture commands and can be set on the vehicle's center console, mobile phone software, or other locations.
[0049] This application also provides a vehicle (not shown in the figures). The vehicle includes the sun visor assembly 1 as described in the above embodiment. It is understood that the vehicle may also include other components, such as a frame, chassis, battery, motor controller, center console, center screen, etc. For the sake of brevity, this embodiment will not provide examples or descriptions of each component. Thus, the technical effects of the vehicle in this embodiment can be found in any of the above embodiments, and will not be repeated here.
