Description

Technical Field

[0001] The invention relates to the field of mirror technology, and in particular to a mirror module with the function of defogging and being able to see through a light source. Background Art

[0002] A mirror is an object with a smooth surface and the ability to reflect light. There are two main types of mirrors: plane mirrors and curved mirrors. Plane mirrors are often used by people to tidy up their appearance. Curved mirrors are divided into concave mirrors and convex mirrors. They are mainly used as dressing mirrors, decorative mirrors, car rearview mirrors, optical instruments, and solar cookers. In science, mirrors are also often used in instruments such as telescopes, lasers, and industrial equipment. They are polished metal devices with regular reflective properties and glass or metal products with metal-plated reflective surfaces, often inlaid with metal, plastic or wooden frames.

[0003] In some specific environments or scenes, such as rainy days, foggy days, and bathrooms, water mist will be generated on the surface, which will affect the imaging effect. As a bathroom mirror, it will affect the imaging effect; as a car rearview mirror, it will cause safety accidents due to poor imaging effect. The traditional method is to use a hydrophobic film or a hydrophilic film, but the effect is not ideal.

[0004] The Chinese invention patent with publication number CN101564254A discloses a defogging bathroom mirror and a preparation method thereof, wherein the bathroom mirror is composed of three layers of a tempered float glass mirror-coated hydrophobic film substrate, a PVB film and an electrically heated glass from the inside to the outside, the tempered float glass mirror-coated hydrophobic film substrate is composed of three layers of a hydrophobic film, a tempered float glass I and a mirror surface from the inside to the outside, the electrically heated glass is composed of two layers of a conductive film and a tempered float glass II from the inside to the outside, and the electrically heated glass is provided with a conductive slurry busbar on the surface of the tempered float glass II near the conductive film. Although this solution has the characteristics of ideal defogging effect, clear imaging and safety and reliability, it still has the following shortcomings:

[0005] (1) The structure is complex, which not only increases the difficulty of processing, but also increases the production cost. In addition, the overall thickness is relatively large, and the usage scenarios are limited;

[0006] (2) PVB film is used as the bonding between two layers of glass. Since PVB film is sensitive to water vapor in the air, if it is exposed for a long time or not properly protected, especially in a humid environment, local debonding may occur at the edges. In a humid environment, PVB laminated glass is prone to water leakage, especially in the rainy season, which to a certain extent affects its service life and stability. In addition, during the processing, PVB laminated glass is particularly prone to cracking, which requires production workers to have high construction skills to ensure safety during the processing and product quality.

[0007] (3) Since the mirror surface is located on the back of the tempered float glass I, when it is used in darker environments, or in scenes that require ambient lighting, or when warning or reminder signs are required on the mirror, it is often necessary to install some light source devices behind the mirror, such as light strips for lighting and creating an atmosphere, alarm lights for warnings or reminders, etc. This requires that the mirror surface area corresponding to the position where the light source device is to be installed on the back of the mirror be scraped in advance; although this treatment can achieve the light source to be seen through the mirror for the user to perceive, it invisibly destroys the integrity of the mirror surface and causes irreversible damage to the mirror surface, that is, imaging can no longer be performed in the scraped area.

[0008] Therefore, a new technical solution is urgently needed to solve the above technical problems. Summary of the invention

[0009] The purpose of the present invention is to overcome the above-mentioned problems of the prior art and provide a mirror module with defogging and light source transparency, so as to solve the problems that the mirror with heating function in the traditional technology has a complex structure and high processing cost; the PVB film is prone to degumming and water seepage in a humid environment, thereby causing the heating layer to fall off; and in order to facilitate the light source to be able to see through the mirror, the mirror coating is scraped off, which affects the integrity of the mirror and the scraped surface cannot continue to form an image.

[0010] The above objectives are achieved through the following technical solutions:

[0011] A mirror module with defogging function and light source viewing function, comprising:

[0012] A transparent substrate, the transparent substrate is light-transmissive and includes a front substrate surface and a rear substrate surface as carrier surfaces;

[0013] A mirror coating, the mirror coating is arranged on the front substrate surface of the transparent substrate for imaging;

[0014] A transparent heating film coating is arranged on the rear substrate surface of the transparent substrate, and positive and negative electrode units are arranged on the outer side of the transparent heating film coating. By energizing the positive and negative electrode units, the transparent heating film coating is heated and heated.

[0015] Furthermore, a light source module is also arranged on the outer side of the transparent heating film coating, and the light source emitted by the light source module can penetrate the transparent heating film coating, the transparent substrate and the mirror coating in sequence.

[0016] Furthermore, the light source module is a light strip, and the light strip is arranged at any position of the outer side surface of the transparent heating film coating.

[0017] Furthermore, the material used for the mirror coating is selected from metal coating, non-metal coating or multi-layer coating.

[0018] Furthermore, the transparent substrate is made of glass or organic glass.

[0019] Furthermore, the transparent heating film coating is an electrically heated transparent film.

[0020] Furthermore, the electrically heated transparent film is made of indium tin oxide.

[0021] Furthermore, the positive and negative electrode units are arranged on the outer side of the transparent heating film coating, including:

[0022] Positive electrode preparation: depositing a primer layer on one edge of the transparent heating film coating, and depositing a layer of electrode material on the primer layer to form a positive electrode;

[0023] Negative electrode preparation: a layer of the base layer is deposited on the other edge of the transparent heating film coating, and a layer of electrode material is deposited on the base layer to form a negative electrode.

[0024] Furthermore, the transparent substrate is a flat surface or a curved surface.

[0025] Furthermore, the thickness of the transparent substrate is 1 mm to 20 mm, the thickness of the mirror coating is 10 nm to 300 nm, and the thickness of the transparent heating film coating is 50 nm to 700 nm.

[0026] The mirror module with defogging and light source perspective provided by the present invention adopts a transparent substrate, and a mirror coating is arranged on the front substrate surface, and a transparent heating film coating is arranged on the rear substrate surface. No adhesive such as PVB film is required for bonding, and the transparent substrate, the mirror coating and the transparent heating coating are formed into a whole, thereby forming a mirror material. When used in different scenes, it only needs to be cut or heated to release the deformation. This mirror module is not only simple in structure and low in production cost, but also can see through the light source module arranged behind the transparent heating film coating, without the need to irreversibly remove the coating on the mirror surface, thereby ensuring the integrity of the mirror surface.

[0041] The present invention is further described in detail below based on the accompanying drawings and embodiments. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 8 As shown, the present solution provides a mirror module with defogging function and light source viewing function, including:

[0043] A transparent substrate 1, wherein the transparent substrate 1 is light-transmissive and includes a front substrate surface 101 and a rear substrate surface 102 as carrier surfaces;

[0044] A mirror coating 2, wherein the mirror coating 2 is disposed on the front substrate surface 101 of the transparent substrate 1 and is used for imaging;

[0045] A transparent heating film coating 3 is provided on the rear substrate surface 102 of the transparent substrate 1, and positive and negative electrode units 4 are provided on the outer side surfaces of the transparent heating film coating 3. By energizing the positive and negative electrode units 4, the transparent heating film coating 3 is heated and heated, thereby removing the water mist attached to the outer surface of the mirror coating 2 at high temperature.

[0046] In the mirror module provided by the present solution, the mirror coating 2 is disposed on the front substrate surface 1 by a coating method or a deposition method, and the transparent heating film coating 3 is disposed on the rear substrate surface 102 by a coating method or a deposition method.

[0047] The coating method used is not limited to electroplating, chemical plating, vacuum plating, heat and spraying;

[0048] The deposition method used is not limited to physical vapor deposition (PVD) and chemical vapor deposition (CVD), among which physical vapor deposition can select evaporation deposition, sputtering deposition and pulsed laser deposition, etc., and chemical vapor deposition can select low pressure chemical vapor deposition (LPCVD), plasma enhanced chemical vapor deposition (PECVD), metal organic compound chemical vapor deposition (MOCVD) and atomic layer deposition (ALD), etc.

[0049] A light source module 5 is also provided on the outer side of the transparent heating film coating 3. The light source emitted by the light source module 5 can penetrate the transparent heating film coating 3, the transparent substrate 2 and the mirror coating 1 in sequence, so that the user can feel the light source on the outer side of the mirror coating 2, thereby realizing functions such as lighting, warning or reminder.

[0050] As a specific embodiment of the present scheme, the light source module 5 is a light strip, which is arranged at any position on the outer side of the transparent heating film coating 3, and the light strip can be set to any shape, such as a ring, etc. The light source emitted can penetrate the transparent heating film coating, the transparent substrate and the mirror coating in turn, providing a bright lighting environment for the user, so that the user can see the image more clearly on the mirror coating.

[0051] It should be noted that since the positive and negative electrodes are generally made of metal materials, such as copper foil, silver paste or other highly conductive materials, and in order to ensure the transparency of the overall mirror device, the positive and negative electrodes will be made as small as possible to minimize their interference with the light source module.

[0052] As a preferred solution, the positive and negative electrodes can be respectively arranged at the edges of the transparent heating film coating.

[0053] The material used for the mirror coating 2 in this embodiment is selected from metal coating, non-metal coating or multi-layer coating;

[0054] Among them, metal coating is one of the most common materials in mirror coating. Common metal coating materials include: aluminum, silver and titanium.

[0055] Non-metallic coating is also a common material in mirror coating. Common non-metallic coating materials include polycarbonate, polyester and polyurethane.

[0056] Multilayer coating is a coating technology that coats one or more layers of other materials on the surface of metal or non-metal materials. Common multilayer coating materials include fluoride, oxide, etc. This multilayer coating technology can improve the imaging effect, wear resistance and UV resistance of the mirror.

[0057] This solution adopts a metal coating, and uses a vacuum magnetron sputtering coating method to set the mirror coating 2 on the front substrate surface 101 of the transparent substrate 1. Specifically, the metal coating material is placed in a vacuum magnetron sputtering coating device, and the metal coating is evenly coated on the front substrate surface of the transparent substrate through magnetron sputtering technology; this step requires precise control of the coating thickness and uniformity to ensure the one-way perspective effect.

[0058] It should be noted that, in order to increase the coating effect, the glass surface may be pre-treated before coating, such as applying a layer of primer or performing other treatments to enhance the adhesion between the coating and the glass.

[0059] The material used for the transparent substrate 1 described in this embodiment is selected from one of glass or organic glass; both of them can meet the transparency requirements of this solution. Among them, glass is not only beautiful in appearance, but also strong and durable, and can play a role in sound insulation and heat insulation; and organic glass, such as acrylic, has good weather resistance and impact resistance.

[0060] The transparent heating film coating 3 is an electrically heated transparent film.

[0061] Specifically, the electrically heated transparent film generates heat through the positive and negative electrode units 4 under the action of an applied voltage; since the thermal inertia of the film is small, the temperature can be controlled more quickly by applying current or voltage; the material can be selected from traditional transparent conductive oxides (TCOs) such as indium tin oxide (ITO), as well as metal nanomaterials (such as copper, silver, gold, etc.) and new materials (such as MXene, graphene, etc.) to improve conductivity and light transmittance, and reduce cost and haze.

[0062] The electrically heated transparent film is made of indium tin oxide.

[0063] As a specific embodiment of the present solution, indium tin oxide is deposited on the rear substrate surface of the transparent substrate by a magnetron sputtering method in a physical vapor deposition method. The specific process is as follows:

[0064] Cleaning the transparent substrate: Use an appropriate cleaning agent to clean the glass substrate to remove impurities such as oil, dust, etc. on the surface; after cleaning, rinse it with deionized water and blow it dry with nitrogen.

[0065] Pretreatment: A silicon dioxide film is formed on the surface of the rear substrate 102 to improve the adhesion of the ITO coating. This is usually achieved by chemical vapor deposition (CVD) or sol-gel methods.

[0066] Prepare ITO target: a ceramic target made by mixing indium oxide (In2O3) and tin oxide (SnO2) in a certain proportion and sintering them.

[0067] Prepare sputtering equipment: prepare magnetron sputtering equipment, including sputtering chamber, target material, substrate rack, power supply, etc.; ensure that the inside of the equipment is clean and free of impurities.

[0068] Vacuuming: Close the door of the sputtering chamber, start the vacuum pump, and extract the air in the sputtering chamber until the required vacuum degree is reached.

[0069] Heating the substrate: Preheat the transparent substrate 1 as needed to improve deposition efficiency and quality.

[0070] Sputtering coating: voltage and current are applied to the target material to generate magnetic and electric fields, so that the atoms or molecules on the surface of the target material are ionized and accelerated, and finally deposited on the glass substrate to form an ITO film. Control the sputtering voltage, current, time and other parameters to obtain the desired coating thickness and performance.

[0071] Annealing treatment: Annealing treatment is performed on the coated glass substrate to eliminate internal stress and improve the stability and performance of the coating.

[0072] Cleaning and drying: Use an appropriate cleaning agent to clean the coated transparent substrate 1 to remove the residue on the surface.

[0073] After cleaning, rinse with deionized water and blow dry with nitrogen.

[0074] In this embodiment, the positive and negative electrode units 4 are arranged on the outer side of the transparent heating film coating 3, including:

[0075] Positive electrode production: depositing a base layer on one edge of the transparent heating film coating 3, and depositing a layer of electrode material on the base layer to form a positive electrode;

[0076] Negative electrode preparation: a layer of the primer layer is deposited on the other edge of the transparent heating film coating 3, and a layer of electrode material is deposited on the primer layer to form a negative electrode.

[0077] In this embodiment, the base layer may be made of materials such as silver paste or copper paste. The function of the base layer is to enhance the adhesion between the electrode material and the transparent conductive film and form a good electrical contact.

[0078] In this embodiment, the electrode material can be copper foil, silver paste or other highly conductive materials; during the deposition process, the thickness and uniformity of the deposition need to be controlled to ensure the conductivity and stability of the positive and negative electrodes.

[0079] A covering layer is deposited on the positive and negative electrode materials. The covering layer can also use materials such as silver paste or copper paste. The function of the covering layer is to protect the electrode material, prevent it from being corroded by the external environment, and further improve the stability and durability of the electrode.

[0080] This solution also provides electrode connection and testing, specifically:

[0081] Electrode connection: Use wires to connect the positive and negative electrodes to the positive and negative electrodes of the power supply respectively for electric heating operation. During the connection process, it is necessary to ensure good contact and stability between the electrode and the wire.

[0082] Testing and adjustment: After the electrode is made, the transparent electric heating film needs to be tested to ensure that its heating performance, conductivity and stability meet the requirements. If necessary, the deposition position, size or material of the electrode can be adjusted and optimized.

[0083] like Figures 1 to 8 As shown, the transparent substrate 1 in this embodiment is a plane or a curved surface, and the mirror coating 2 and the transparent heating film coating 3 also match the shapes of the corresponding front substrate surface and rear substrate surface. It should be noted that the mirror module in this embodiment can be cut into various shapes according to application needs, such as a common plane ellipse, a plane square, or a hemispherical shape.

[0084] like Figure 1 to Figure 5 As shown, the thickness of the transparent substrate 1 is 1 mm to 20 mm, the thickness of the mirror coating 2 is 10 nm to 300 nm, and the thickness of the transparent heating film coating 3 is 50 nm to 700 nm.

[0085] As a first specific embodiment of this solution, the thickness of the transparent substrate 1 is 1 mm, the thickness of the mirror coating 2 is 10 nm, and the thickness of the transparent heating film coating 3 is 50 nm;

[0086] As a second specific embodiment of the present solution, the thickness of the transparent substrate 1 is 10 mm, the thickness of the mirror coating 2 is 150 nm, and the thickness of the transparent heating film coating 3 is 350 nm;

[0087] As a third specific embodiment of the present solution, the thickness of the transparent substrate 1 is 20 mm, the thickness of the mirror coating 2 is 300 nm, and the thickness of the transparent heating film coating 3 is 700 nm.

[0088] The above description is only for illustrating the implementation mode of the present invention and is not intended to limit the present invention. For those skilled in the art, any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
