Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, the vehicle-mounted sun visor cosmetic mirror with an electrochromic function of the present invention includes a fixing base, a backlight module 1, electrochromic glass 2, and a control unit. The backlight module 1 and the electrochromic glass 2 are arranged in the fixing seat, the opening and closing of the backlight module 1 and the light transmittance of the electrochromic glass 2 are controlled through the control unit, namely, the optical properties of the electrochromic glass 2 are utilized, including reflectivity, transmittance, absorptivity and the like, a reversible and stable color change phenomenon occurs under the action of an external electric field, the reversible change of the color and the transparency of the electrochromic glass 2 is mainly expressed, so that the transmittance of visible light is adjusted, the passenger face can be clearly observed under the condition of insufficient light such as night, and the light is soft and is not dazzling.
To achieve the above object, the components of the vehicle sun visor vanity mirror may be arranged in various ways, and the configuration of the components will be described in detail below by taking a specific embodiment as an example.
The fixing seat can be made of plastic and the like, and the inside of the fixing seat is an accommodating cavity with an opening on the front side. And the periphery of the front surface of the fixing seat is provided with a convex clamping edge, and the backlight module 1 and the electrochromic glass 2 are clamped in the accommodating cavity of the fixing seat.
The backlight module 1 is close to the back of the fixing seat, and can be a side-in type backlight module or a direct type backlight module to meet various use requirements. As shown in fig. 1, when the backlight module is a side-in type, it includes a frame fixed in a fixing base, an LED lamp 11 fixed in the frame, and a reflective film 12 fixed in the frame. The frame body can be a rubber frame consisting of a rubber frame and an iron frame, and can also be an independent iron frame, so that the cost is reduced. The LED lamp 11 is fixed to a side portion of the frame, and light emitted from the LED lamp 11 is reflected by the reflective film 12 into the electrochromic glass 2. So set up, under the prerequisite of guaranteeing to satisfy user demand, reduce backlight unit 1's cost as far as possible to reduce the cost of on-vehicle sunshading board vanity mirror as far as possible.
As shown in fig. 2, when the direct type backlight module is used, it includes a frame fixed in a fixing base, a lamp 13 fixed in the frame, and a diffusion film 14 fixed above the lamp 13. The frame body can be a rubber frame consisting of a rubber frame and an iron frame, and can also be an independent iron frame, so that the cost is reduced. The lamp tube 13 is fixed to the bottom of the housing, and light emitted therefrom is diffused by the diffusion film 14 and then incident on the electrochromic glass 2. So set up, under the prerequisite of guaranteeing to satisfy user demand, reduce backlight unit 1's cost as far as possible to reduce the cost of on-vehicle sunshading board vanity mirror as far as possible.
The electrochromic glass 2 is close to the front of the fixed seat, a gap is reserved between the electrochromic glass and the backlight module 1, and the gap is filled with air. When a gap is left between the electrochromic glass 2 and the backlight module 1, light coming out of the backlight module 1 is subjected to diffuse reflection in the air firstly, further uniform light is realized, and then the light enters the electrochromic glass 2, so that the uniformity of the light entering the electrochromic glass 2 is improved, meanwhile, an optical film of the backlight module 1 only comprises a reflection film 12 or a diffusion film 14, and the cost of the backlight module 1 is reduced.
The electrochromic glass 2 comprises a first glass substrate 21, a first transparent conducting layer 22, an ion storage layer 23, an electrolyte layer 24, an electrochromic layer 25, a second transparent conducting layer 26 and a second glass substrate 27 which are sequentially stacked, wherein the first glass substrate 21 is close to the backlight module 1. When a certain voltage is applied between the first transparent conductive layer 22 and the second transparent conductive layer 26 of the electrochromic glass 2, the electrochromic layer 25 undergoes an oxidation-reduction reaction under the action of the voltage, and the color and the transmittance change. The backlight module 1 is matched at the bottom of the electrochromic glass 2, when the transmittance of the electrochromic glass 2 is increased, namely when a certain polarity voltage is applied, the color of the electrochromic layer 25 is lightened, the visible light transmittance is increased, the overall reflectivity of the vehicle-mounted sun visor cosmetic mirror is reduced, the transmitted light quantity of the backlight module 1 is increased, more light quantity is transmitted, the light supplementing effect can be achieved, and the electrochromic glass 2 can be used as the cosmetic mirror under the condition of insufficient light such as at night; when the transmittance of the electrochromic glass 2 is lowered, that is, when the polarities of the voltages are opposite, the color of the electrochromic layer 25 is deepened and the transmittance of visible light is reduced, at this time, the reflectance of the whole vehicle sun visor cosmetic mirror is raised and the mirror is opaque, at this time, the electrochromic glass 2 can be used as a cosmetic mirror under the condition of sufficient light, for example, in the daytime.
The fact that the reflectivity of the vehicle-mounted sun visor vanity mirror is increased and the mirror is opaque means that the electrochromic glass 2 is substantially opaque, that is, the electrochromic glass 2 is completely opaque or transmits a small amount of light, and even if a small amount of light is transmitted, the use of the mirror is not substantially affected.
The electrochromic layer 25 is made of a material that can undergo a reversible color change under the action of an applied low driving voltage or current, in which the valence state and components of the material undergo a reversible change, so that the optical properties of the material are changed or remain changed. Meanwhile, the electrochromic layer 25 is required to have excellent ionic conductivity, high contrast, high color change efficiency, cycle period, and other electrochromic properties. Materials constituting the electrochromic layer 25 are classified into inorganic electrochromic materials and organic electrochromic materials. A typical representative of inorganic electrochromic materials is tungsten trioxide. The organic electrochromic material mainly comprises polythiophene and derivatives thereof, viologen, tetrathiafulvalene, metal phthalocyanine compounds and the like. Preference is given here to materials of the viologen type which better satisfy the following requirements: the fast color change response is that the response time to the electric field is fast; a reversible change in color; the color change is highly sensitive, namely the color change efficiency is high; the cycle service life is longer; stable chemical property and good durability to high temperature.
The control unit comprises a control circuit connected with the backlight module 1 and the electrochromic glass 2, a control module connected with the control circuit, and a rotary button electrically connected with the control module and fixed on the fixed seat. The structure of the control circuit is set according to the requirements, and is not described in detail herein. The control module controls the rotary button to ensure that the backlight module 1 does not emit light and the electrochromic glass 2 is transparent when the rotary button is positioned at a closed position; when the rotary button is turned on and is positioned at the first gear, the backlight module 1 emits visible light and the electrochromic glass 2 transmits part of the visible light; when the rotary button is opened and is positioned at the second gear, the backlight module 1 emits visible light and the electrochromic glass 2 is not transparent. Due to the arrangement, the operation is simple and convenient through rotating the button; when the light is sufficient, the face state can be well illuminated by the electrochromic glass 2, and the user experience is improved.
Further, the indicator (for example, a moon-shaped indicator) indicating the first gear and the indicator (for example, a sun-shaped indicator) indicating the second gear are located on both sides of the indicator (for example, a closed indicator with a bad shape in a circle) indicating the closed position. The rotary button is installed at the downside of fixing base, and wherein when on-vehicle sunshading board vanity mirror is opened, the downside of fixing base is towards the vehicle bottom, also when on-vehicle sunshading board vanity mirror is opened, keeps away from the one side of roof. So set up to further improve the simple operation nature, improve user experience.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
