Description

TECHNICAL FIELD

[0001] The utility model relates to toughened film technical field, specifically is an anti-impact toughened film. BACKGROUND

[0002] In today's digital age, electronic devices such as mobile phones, tablet computers, smart watches, etc. have become an indispensable tool in people's life and work. However, the screens of these devices are subject to many threats in daily use and are extremely vulnerable to damage. Whether it is accidental dropping, collision, or scratching with other hard objects, it can cause scratches, cracks, or even complete damage to the screen, not only affecting the appearance of the device, but also seriously affecting its normal use, causing great inconvenience and economic loss to the user.

[0003] Traditional tempered films can provide protection for electronic device screens to some extent. They usually only have a simple tempered glass material body and mainly prevent the screen from being lightly scratched. However, when the device is subjected to a more intense impact, such tempered films often prove to be inadequate. Due to the lack of effective buffer structures, the impact force will directly act on the screen, causing the tempered film to break and the screen to be damaged. Moreover, traditional tempered films have obvious defects in edge protection. The edges of the device are the most vulnerable parts to bumps, and ordinary tempered films cannot fully protect the edges, causing the screen edges to be prone to edge collapse, cracking, and other problems.

[0004] To this end, it is necessary to propose an improved technical solution to solve the above problems. INVENTION CONTENTS

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1) Through the design that the height of the elastic buffer layer is greater than the thickness of the tempered film main body, when the electronic device falls or is impacted, the elastic buffer layer can effectively absorb and disperse the impact force, greatly reduces the probability of breakage of the tempered film main body and damage of the screen of the electronic device, significantly enhances the impact resistance of the tempered film, and provides more reliable protection for the screen of the electronic device.

[0020] 2) The existence of the wear-resistant outer layer not only prevents the elastic buffer layer from being scratched and worn, but also tightly cooperates with the elastic buffer layer to maintain the structural integrity and functional effectiveness of the frame assembly during long-term use, ensures that the tempered film can stably play the roles of impact resistance and edge protection for a long time, and guarantees the long-term protection performance.

[0021] 3) Since the frame assembly surrounds the edge area of the tempered film main body, and the elastic buffer layer and the wear-resistant outer layer jointly act, the device edge, which is prone to be impacted, is provided with all-round protection, the buffer effect of the elastic buffer layer and the wear-resistant protection of the wear-resistant outer layer effectively prevent the screen edge from appearing problems such as edge collapse and fragmentation, and prolong the service life of the tempered film and the screen of the electronic device.

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0029] Please refer to Figs. 1-2 In the embodiments of the present application, an impact-resistant tempered film comprises:

[0030] The tempered film main body 1 has a bonding surface for bonding with the screen of an electronic device and an opposite non-bonding surface.

[0031] The frame assembly 2 is arranged at the edge region of the tempered film main body 1, and comprises at least one elastic buffer layer 3 and a wear-resistant outer layer 4 arranged on the surface of the elastic buffer layer 3, and the extension range of the wear-resistant outer layer 4 around the edge of the tempered film main body 1 is consistent with that of the elastic buffer layer 3.

[0032] In the present application, the height of the elastic buffer layer 3 is greater than the thickness of the tempered film main body 1.

[0033] In the technical solution of the present application:

[0034] When the electronic device is subjected to impact, the frame assembly 2 is the first to contact the external impact force. The elastic buffer layer 3, which has a height greater than the thickness of the tempered film body 1, can first contact the external object. The elastic buffer layer 3 is made of a high polymer material such as silicone or TPU, which has elastic and buffering properties. The elastic buffer layer 3 itself has good flexibility and elastic deformation capability. When the impact force is applied, the elastic buffer layer 3 absorbs and disperses the impact force through its elastic deformation, converts the concentrated impact force into a more dispersed force, and avoids the impact force acting directly on the tempered film body 1 and the electronic device screen, thereby playing a buffering protection role.

[0035] The wear-resistant outer layer 4 in the frame assembly 2 is arranged on the surface of the elastic buffer layer 3 and has the same extension range as the elastic buffer layer 3 around the edge of the tempered film body 1. This design makes the frame assembly 2 form a stable structure as a whole. The wear-resistant outer layer 4 is made of a plastic, metal or ceramic material with a higher hardness than the elastic buffer layer 3. These materials have high strength and wear resistance, so that the wear-resistant outer layer 4 can enhance the overall strength of the frame assembly 2, prevent the elastic buffer layer 3 from being damaged by external scratching and wear during long-term use, and ensure that the elastic buffer layer 3 can always play a normal buffering function. At the same time, the wear-resistant outer layer 4 is tightly combined with the elastic buffer layer 3 to form a package around the edge of the tempered film body 1, further improving the stability of the entire tempered film structure.

[0036] In summary, through the design that the height of the elastic buffer layer 3 is greater than the thickness of the tempered film body 1, when the electronic device falls or is subjected to impact, the elastic buffer layer 3 can effectively absorb and disperse the impact force, greatly reducing the probability of breakage of the tempered film body 1 and damage to the electronic device screen, and significantly enhancing the impact resistance of the tempered film, thereby providing more reliable protection for the electronic device screen.

[0037] The existence of the wear-resistant outer layer 4 not only prevents the elastic buffer layer 3 from being scratched and worn, but also cooperates with the elastic buffer layer 3 to maintain the structural integrity and functional effectiveness of the frame assembly 2 during long-term use, ensuring that the tempered film can stably play the role of impact resistance and edge protection for a long time, thereby ensuring long-term protection performance.

[0038] Since the frame assembly 2 surrounds the edge area of the tempered film body 1, and the elastic buffer layer 3 and the wear-resistant outer layer 4 jointly act on the device edge, which is prone to be bumped, to provide all-round protection. The buffering effect of the elastic buffer layer 3 and the wear-resistant protection of the wear-resistant outer layer 4 effectively prevent the screen edge from being damaged, such as edge collapse and cracking, thereby prolonging the service life of the tempered film and the electronic device screen.

[0039] The wear-resistant outer layer 4 is combined with the elastic buffer layer 3 in the mode of injection molding, coating or sticking.

[0040] The injection molding process can make the wear-resistant outer layer 4 material be formed in the mold and be closely embedded with the elastic buffer layer 3, and form a firm integrated structure; the coating can uniformly cover the wear-resistant material on the surface of the elastic buffer layer 3, and enhance the close degree of combination of the two; the sticking is to precisely stick the wear-resistant outer layer 4 on the elastic buffer layer 3 by using a special adhesive; no matter which mode, the wear-resistant outer layer 4 can enhance the overall strength of the frame assembly 2, effectively prevent the elastic buffer layer 3 from being damaged by external scratches and wear in long-term use, and ensure that the elastic buffer layer 3 can always normally play a buffering role; meanwhile, the wear-resistant outer layer 4 is closely attached to the elastic buffer layer 3, and together forms a package for the edges of the tempered film main body 1, and further improves the stability of the whole tempered film structure.

[0041] In the embodiment of the utility model, the edge of tempered film main body 1 extends and is provided with a connecting frame part 5, the frame assembly 2 is connected with the connecting frame part 5.

[0042] The outer side of the connecting frame part 5 is provided with a groove 6 surrounding the tempered film main body 1 in a ring shape, and the inner side of the elastic buffer layer 3 is provided with a protruding part 7 matched with the groove 6.

[0043] When the protruding part 7 is embedded in the groove 6, the two are matched with each other, and the relative displacement of the frame assembly 2 and the connecting frame part 5 in the horizontal direction is limited, since the groove 6 surrounds the tempered film main body 1 in a ring shape, it is ensured that a stable connection basis can be provided in the whole edge area, so that the frame assembly 2 can be evenly and closely surrounded on the edge of the tempered film main body 1, and the stability of the overall structure is enhanced; meanwhile, the structure design of the close cooperation of the two can make the impact force more evenly dispersed to the connecting parts of the whole frame assembly 2 and the tempered film main body 1 when an external force impact is received, so as to avoid the local excessive stress leading to connection failure;

[0044] The protruding part 7 on the inner side of the elastic buffer layer 3 cooperates with the groove 6 of the connecting frame part 5, not only realizes the physical connection, but also plays a synergistic role in the buffering process; when the equipment is impacted, the elastic buffer layer 3 firstly absorbs and disperses part of the impact force through its elastic deformation, at this time, the protruding part 7 will produce a certain displacement in the groove 6 along with the deformation of the elastic buffer layer 3, but due to the restriction of the groove 6 on the protruding part 7, the elastic buffer layer 3 can more stably transmit the buffering force to the connecting frame part 5 in the deformation process, and then to the tempered film main body 1, so that the whole buffering process is more efficient and orderly, and the protection effect on the screen of the electronic equipment is enhanced;

[0045] In order to further enhance the connection strength, the surface of the elastic buffer layer 3 in contact with the connecting frame part 5 is coated with a high-strength adhesive to fill the fine gap between them and make them tightly bonded together.

[0046] In the embodiment of the utility model, the outer side wall of the wear-resistant outer layer 4 is provided with anti-skid lines 8, the anti-skid lines 8 surround the wear-resistant outer layer 4 in a uniformly spaced manner, and are distributed in a continuous wavy or short linear interlaced manner.

[0047] The anti-skid lines 8 provided on the outer side wall of the wear-resistant outer layer 4 increase the friction by increasing the surface roughness. When the user holds the electronic device, the lines come into contact with the user's fingers or palm, the concave-convex structure between the lines increases the contact area and friction with the skin, and during the long-time holding of the device by the user, the lines of different shapes can provide appropriate support and friction at different positions, disperse the hand pressure, reduce the hand fatigue, and improve the comfort and stability of holding.

[0048] In the embodiment of the utility model, the non-adhesion surface of the tempered film main body 1 is provided with an anti-glare coating;

[0049] The adhesion surface of the tempered film main body 1 is provided with an electrostatic adsorption layer.

[0050] The anti-glare coating significantly reduces the reflection of ambient light, greatly improving the visibility of the screen of the electronic device in a strong light environment; the electrostatic adsorption layer enables the tempered film to be easily installed on the surface of the screen of the electronic device, and the user only needs to align the tempered film with the screen and gently put it down, and the electrostatic attraction can automatically adhere it, so that the installation process is simple and fast.

[0051] It is obvious for those skilled in the art that the utility model is not limited to the details of the above exemplary embodiments, and can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the utility model is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model.
