Description

Technical Field

[0001] This utility model relates to the field of tempered glass protective film technology, and in particular to a tempered glass protective film with a heat dissipation path. Background Technology

[0002] Tempered glass screen protectors are protective films specifically designed to protect mobile phone screens. They are highly strong and scratch-resistant, effectively preventing damage and scratches from external forces while increasing impact absorption. Tempered glass screen protectors have a smoother feel than ordinary plastic films and offer better light transmission without affecting the screen's visual effect.

[0003] With technological advancements, smartphones are equipped with more powerful processors, graphics chips, and more RAM to support complex applications and games, resulting in a significant amount of heat generated by the internal hardware during use. If this heat cannot be dissipated effectively and promptly, it will cause the device temperature to rise, affecting performance stability, shortening battery life, and potentially causing hardware damage. Therefore, effective heat dissipation measures are crucial for maintaining the optimal operating condition of a smartphone.

[0004] Most smartphones on the market today have internal heat dissipation designs to help cool down the internal hardware. However, during prolonged high-load operation, the temperature of the phone screen itself also rises. At the same time, the internal heat dissipation design cannot fully meet the cooling needs of the internal hardware, so the heat from the internal hardware is dissipated to the outside through the phone screen to improve the heat dissipation effect. However, traditional tempered glass screen protectors mainly focus on providing physical protection to prevent the screen from scratches and impacts, and contribute almost nothing to heat dissipation. Moreover, the application of tempered glass screen protectors will cover the phone screen, reducing the heat dissipation path of the screen and affecting the screen's heat dissipation performance to some extent, resulting in the phone temperature not being effectively controlled.

[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tempered glass protective film with a heat dissipation path, comprising a tempered glass base layer and an adhesive layer;

[0008] A heat-conducting layer is provided between the tempered glass base layer and the adhesive layer, and a first adhesive interlayer is provided between the heat-conducting layer and the tempered glass base layer;

[0009] A heat-conducting sheet is provided around the edge of the tempered glass base layer, and the edge of the heat-conducting layer is in contact with the heat-conducting sheet.

[0010] As a further embodiment of this invention, the thermally conductive layer is made of graphene film.

[0011] As a further embodiment of this utility model: the edge of the lower end face of the tempered glass base layer is CNC die-cut into a concave platform structure, and the heat-conducting sheet is disposed in the concave platform structure.

[0012] As a further embodiment of this utility model: the outer surface of the heat-conducting sheet has heat dissipation grooves arranged along the edge.

[0013] As a further embodiment of this utility model: a second adhesive interlayer is provided between the contact surface of the heat-conducting sheet, the tempered glass base layer, and the heat-conducting layer.

[0014] As a further embodiment of this utility model: the upper surface of the tempered glass base layer is provided with a silkscreened border;

[0015] The width of the silkscreen border is at least greater than the width of the heat-conducting sheet.

[0016] As a further embodiment of this utility model: the upper surface of the tempered glass base layer is provided with an anti-fingerprint coating.

[0017] Compared with existing technologies, the beneficial effects of this technical solution are as follows: During the use of the mobile phone, the heat emitted by the screen is absorbed by the heat-conducting layer at the bottom of the tempered glass base layer and conducted to the heat-conducting sheet. The side of the heat-conducting sheet surrounding the edge of the tempered glass base layer is in contact with the external air. The heat-conducting sheet dissipates the absorbed heat to the external environment to form a heat dissipation path, thereby achieving efficient heat conduction, improving the heat dissipation efficiency of the mobile phone screen, effectively solving the problem of heat accumulation inside the screen, thus significantly improving the overall heat dissipation efficiency of the mobile phone, reducing problems such as device lag and internal hardware damage caused by overheating, providing a smoother user experience, and keeping the mobile phone in good working condition.

[0018] Furthermore, the thermal conductive layer is made of graphene film, which has extremely high transparency and thermal conductivity, enabling efficient heat transfer in a very thin layer. This allows the thermal conductive layer made of graphene film to be bonded to the tempered glass base layer through the first adhesive interlayer, while maintaining the high light transmittance of the tempered film, thus combining the physical protection function and heat dissipation characteristics of traditional tempered film.

[0019] A recessed platform structure is machined around the lower end face of the tempered glass base using CNC die-cutting technology, and the heat-conducting plate is placed in the recessed platform structure. This allows the upper end face of the tempered glass base to cover the heat-conducting plate, effectively preventing users from touching the heat-conducting plate with their fingers during use, preventing the heat-conducting plate from overheating and burning the user, and avoiding affecting the user's user experience.

[0020] The heat dissipation grooves on the side of the heat-conducting plate further increase the heat dissipation surface area and can also guide air to flow along the grooves to form natural convection. This convection effect helps to remove more heat, especially in outdoor environments. The heat dissipation grooves can make better use of natural wind power, further enhancing heat dissipation performance and ensuring that the equipment can still operate stably under extreme conditions.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-3 A tempered glass protective film with a heat dissipation path includes a tempered glass base layer 1 and an adhesive layer 2.

[0030] A heat-conducting layer 3 is provided between the tempered glass base layer 1 and the adhesive layer 2, and a first adhesive interlayer 4 is provided between the heat-conducting layer 3 and the tempered glass base layer 1.

[0031] A heat-conducting sheet 5 is provided around the edge of the tempered glass base layer 1, and the edge of the heat-conducting layer 3 is in contact with the heat-conducting sheet 5.

[0032] In this embodiment of the invention, the mobile phone screen is cleaned to ensure that the screen surface is free of dust and impurities. Then, it is attached to the mobile phone screen through the adhesive layer 2. During the use of the mobile phone, the heat dissipated by the screen is absorbed by the heat-conducting layer 3 at the lower end of the tempered glass base layer 1 and conducted to the heat-conducting sheet 5. The side of the heat-conducting sheet 5 surrounding the edge of the tempered glass base layer 1 is in contact with the outside air. The heat-conducting sheet 5 dissipates the absorbed heat to the external environment to form a heat dissipation path, thereby achieving efficient heat conduction, improving the heat dissipation efficiency of the mobile phone screen, effectively solving the problem of heat accumulation inside the screen, and thus significantly improving the overall heat dissipation efficiency of the mobile phone. This reduces problems such as device lag and internal hardware damage caused by overheating, provides a smoother user experience, and keeps the mobile phone in good working condition.

[0033] Furthermore, the thermal conductive layer 3 is made of graphene film. Graphene film has extremely high transparency and extremely high thermal conductivity, which can achieve efficient heat transfer in a very thin layer. This allows the thermal conductive layer 3 made of graphene film to be combined with the tempered glass base layer 1 through the first adhesive interlayer 4, so that the tempered film can maintain high light transmittance while maintaining high thermal conductivity, thus combining the physical protection function and heat dissipation characteristics of traditional tempered film.

[0034] In this embodiment, it is further proposed that a recessed structure 6 is formed by CNC die-cutting the edge of the lower end face of the tempered glass base 1, and the heat-conducting sheet 5 is disposed in the recessed structure 6.

[0035] A recessed platform structure 6 is manufactured around the lower end face of the tempered glass base 1 using CNC die-cutting technology, and a heat-conducting plate 5 is placed in the recessed platform structure 6. This allows the upper end face of the tempered glass base 1 to cover the heat-conducting plate 5, thereby effectively preventing the user's fingers from coming into contact with the heat-conducting plate 5 during use, preventing the heat-conducting plate 5 from getting too hot and burning the user, and avoiding affecting the user's user experience.

[0036] In this embodiment, it is further proposed that the outer surface of the heat-conducting sheet 5 has heat dissipation grooves 7 arranged along the edge;

[0037] The heat dissipation grooves 7 on the side of the heat conduction plate 5 further increase the heat dissipation surface area and can also guide air to flow along the grooves to form natural convection. This convection effect helps to remove more heat. Especially in outdoor environments, the heat dissipation grooves can make better use of natural wind power, further enhancing heat dissipation performance and ensuring that the equipment can still operate stably under extreme conditions.

[0038] In this embodiment, a second adhesive interlayer 8 is further provided between the contact surfaces of the heat-conducting sheet 5, the tempered glass base layer 1, and the heat-conducting layer 3; the top surface of the heat-conducting sheet 5 and the side facing the tempered glass base layer 1 and the heat-conducting layer 3 are bonded and fixed by the second adhesive interlayer 8, and the design of the recessed platform structure 6 also increases the contact surface between the heat-conducting sheet 5 and the tempered glass base layer 1 to two sides, thereby improving the bonding strength of the heat-conducting sheet 5, preventing the heat-conducting sheet 5 from separating, and ensuring the integrity of the whole.

[0039] In this embodiment, it is further proposed that the upper surface of the tempered glass base layer 1 is provided with a silkscreened border 9;

[0040] Among them, the width of the silkscreen border 9 is at least greater than the width of the heat-conducting sheet 5.

[0041] The silkscreened border 9, which is wider than the heat-conducting sheet 5, can effectively cover the heat-conducting sheet 5, so that users cannot directly see the heat-conducting sheet 5, as well as the traces at the connection between the heat-conducting sheet 5 and the tempered glass base layer 1 and the heat-conducting layer 3, thereby improving the overall visual aesthetics.

[0042] In this embodiment, it is further proposed that the upper surface of the tempered glass base layer 1 is provided with an anti-fingerprint coating 10.

[0043] The anti-fingerprint coating 10 has low surface energy properties, which makes it difficult for fingerprints and oil stains to adhere to the surface of the tempered glass base layer 1. Even if there are a few fingerprints, they are easy to wipe clean, maintaining the clarity of the screen.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
