Description

Technical Field

[0001] This application relates to the field of protective film technology, specifically a hardened, explosion-proof, high-definition automotive screen protective film. Background Technology

[0002] Car infotainment screen protector (also known as in-vehicle display screen protector or car navigation screen protector) is a surface protective film designed specifically for in-vehicle displays such as center console screens and dashboards. It achieves protection, display optimization, and enhanced safety through multi-layer functional coatings and a special structure.

[0003] An existing patent (publication number: CN212499215U) discloses a luminous anti-glare screen protector, including a fixing frame and an installation frame. The installation frame has a fixing frame on its front side, a fixing magnetic strip B is fixedly adhered to the front side of the installation frame, a fixing magnetic strip A is fixedly adhered to the rear side of the fixing frame, and handles are symmetrically fixedly adhered to the upper and lower sides of the center of the front side of the fixing frame. A tempered glass film is fixedly adhered to the inner wall of the fixing frame, and the front side of the tempered glass film has integrally formed frosted particles. This invention places the fixing frame in front of the installation frame, allowing the fixing frame to be attracted to the front of the installation frame via fixing magnetic strips B and A. This allows the tempered glass film to adhere tightly to the surface of the central control screen, making it convenient to fix and attach the tempered glass film during actual use. This greatly simplifies the work of applying screen protectors to automotive central control screens, and the pre-alignment of the installation frame 5 effectively prevents the tempered glass film from being applied crookedly.

[0004] However, during the bonding process, because the tempered glass screen protector is fixed by a magnetic frame, a closed cavity is formed between the screen protector and the screen. During the bonding process, air can only escape naturally through the edge of the screen protector. It is impossible to establish a directional air venting channel, which makes it easy for air bubbles to get trapped under the screen protector. Repeated pressing or the use of a scraper to assist in air venting is required, which is inefficient and can easily damage the screen protector. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a hardened, explosion-proof, high-definition automotive screen protector, which has advantages such as easy installation and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a hardened explosion-proof high-definition vehicle screen protector, comprising a transparent substrate, a hardened coating, an oleophobic and hydrophobic layer, and an adhesive layer, wherein the hardened coating is disposed on the surface of the transparent substrate facing the external environment;

[0007] The oleophobic and hydrophobic layer is disposed on the surface of the hardened coating;

[0008] The adhesive layer is disposed on the surface of the transparent substrate opposite to the hardened coating;

[0009] A set of auxiliary positioning lines are provided on the surface of the transparent substrate;

[0010] A set of air guiding channels is provided on the surface of the transparent substrate, and the inner top wall of the air guiding channel and the side of the adhesive layer near the transparent substrate are on the same reference plane.

[0011] The adhesive surface of the adhesive layer is covered with a release film.

[0012] Furthermore, the thickness of the transparent substrate is 0.2mm-0.6mm, and the visible light transmittance is ≥92%.

[0013] The above solution ensures mechanical strength while maximizing the restoration of the screen's original image quality.

[0014] Furthermore, the contact angle between the oleophobic and hydrophobic layer and water is ≥115°, and the contact angle with oil is ≥90°.

[0015] Through the above solution, a stable anti-pollution barrier is formed on the surface of the protective film, effectively blocking the penetration of fingerprints, oil stains and liquids.

[0016] Furthermore, each of the aforementioned air channels has a microgroove structure parallel to the edge of the transparent substrate.

[0017] The above solution optimizes the airflow path by using a parallel arrangement of micro-grooves, thereby improving exhaust efficiency and avoiding obstruction of the display area.

[0018] Furthermore, the surface pencil hardness of the hardened coating is ≥6H, and the hardened coating has a hardness of ≥6H.

[0019] The above solutions significantly enhance the membrane's resistance to scratches from sharp objects, ensuring no scratches even after long-term use.

[0020] Furthermore, the width of the air guide channel is 0.05mm-0.3mm, and the depth is 0.01mm-0.05mm.

[0021] The above solution, through precise control of the microchannel size, achieves efficient air venting while ensuring no loss of touch sensitivity after film application.

[0022] Furthermore, a set of auxiliary positioning marks are distributed at the four corners of the transparent substrate, and each auxiliary positioning mark is parallel to the edge line of the transparent substrate.

[0023] The above scheme provides a multi-directional positioning reference by using a marking structure distributed in parallel at the four corners, thereby reducing the risk of bonding deviation on complex curved screens.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] This hardened explosion-proof high-definition vehicle screen protector features a design with air channels on the transparent substrate surface and the adhesive layer reference surface that are coplanar. This design creates a directional airflow path during the application process. Combined with the air channel structure, it can quickly expel air, reducing the generation of air bubbles inside the film. It does not require the use of auxiliary tools such as scrapers, thus solving the problem of repeated pressing to expel air required by traditional magnetic film application.

[0026] The transparent substrate features auxiliary positioning lines distributed parallel at the four corners. Combined with the 0.2mm-0.6mm thickness of the transparent substrate, the film can perfectly fit 2D / 2.5D / 3D curved screens. Through the setting of a hardened coating with a surface pencil hardness of ≥6H and an oleophobic and hydrophobic layer with contact angles, the protective film can effectively improve scratch resistance and fingerprint resistance while maintaining a visible light transmittance of ≥92%.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a hardened explosion-proof high-definition vehicle screen protector includes a transparent substrate 1, a hardened coating 2, an oleophobic and hydrophobic layer 3, and an adhesive layer 4. The transparent substrate 1 has a thickness of 0.2mm-0.6mm and a visible light transmittance of ≥92%, ensuring mechanical strength while maximizing the restoration of the screen's original image quality. The hardened coating 2 is applied to the surface of the transparent substrate 1 facing the external environment, and its surface pencil hardness is ≥6H. The ≥6H hardened coating 2 significantly enhances the film's resistance to scratches from sharp objects, ensuring long-term scratch-free use.

[0034] Please see Figure 1 , Figure 2 and Figure 3 An oleophobic and hydrophobic layer 3 is set on the surface of the hardened coating 2. Through the setting of the hardened coating 2 and the oleophobic and hydrophobic layer 3, the protective film has high hardness and scratch resistance and long-lasting oleophobic and hydrophobic properties, which doubles the screen protection effect. The contact angle between the oleophobic and hydrophobic layer 3 and water is ≥115° and the contact angle with oil is ≥90°, which makes the surface of the protective film form a stable anti-pollution barrier and effectively blocks fingerprints, oil stains and liquid penetration.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The adhesive layer 4 is disposed on the other side of the transparent substrate 1 opposite to the hardened coating 2. A set of auxiliary positioning marks 5 are provided on the surface of the transparent substrate 1. The auxiliary positioning marks 5 are used to provide a visual reference when applying the protective film, so as to achieve precise alignment and bonding with the edge of the vehicle screen. The set of auxiliary positioning marks 5 are distributed at the four corners of the transparent substrate 1, and each auxiliary positioning mark 5 is parallel to the edge line of the transparent substrate 1. Through the parallel distribution of marks at the four corners, a multi-directional positioning reference is provided, reducing the risk of bonding deviation of complex curved screens.

[0036] Please see Figure 1 , Figure 2 and Figure 3 A set of air guiding channels 6 is provided on the surface of the transparent substrate 1. The inner top wall of the air guiding channel 6 and the side of the adhesive layer 4 near the transparent substrate 1 are on the same reference plane. By setting the air guiding channel 6, air is guided to be discharged in a directional manner during the bonding process, completely eliminating air bubbles and ensuring the flatness of the film surface. The set of air guiding channels 6 are all in the form of micro-groove structures parallel to the edge of the transparent substrate 1. Through the parallel arrangement of the micro-grooves, the airflow outlet path is optimized, the exhaust efficiency is improved, and the display area is avoided from being blocked.

[0037] Please see Figure 1 , Figure 2 and Figure 3 The air channel 6 has a width of 0.05mm-0.3mm and a depth of 0.01mm-0.05mm. Through precise control of the microchannel size, efficient exhaust is achieved while ensuring that the touch sensitivity is not compromised after the film is applied. The adhesive surface of the adhesive layer 4 is covered with a release film 7. The release film 7 isolates dust from contaminating the adhesive layer 4 and maintains the initial adhesion and cleanliness of the adhesive layer 4.

[0038] It should be noted that when removing the release film 7, slowly peel it off from the corner corresponding to any of the auxiliary positioning marks 5, avoiding direct contact of the adhesive layer 4 with your fingers, and align the four corner marks of the transparent substrate 1 with the edge of the screen one by one to ensure that the marks are parallel to the screen outline.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
