Description

Technical Field

[0001] The utility model relates to the technical field of display screen accessories, in particular to an electronic equipment protective film. Background Art

[0002] When users use electronic devices such as mobile phones and tablet computers, in order to prevent the display screens of the electronic devices from being scratched, they generally stick a layer of protective film on the surface of the display screens to protect the display screens and thus prevent the display screens from being scratched.

[0003] At present, the protective film usually includes a first release layer, a protective layer and a second release layer stacked in sequence. Among them, the protective layer is usually a hydrogel film or a tempered glass film. The first release layer and the second release layer are used to protect the front and back sides of the protective layer. A first adhesive layer is provided on the side of the protective layer facing the first release layer, and the first release layer covers the first adhesive layer. A second adhesive layer is provided on the side of the second release layer facing the protective layer, and the second release layer is adhered to the protective layer through the second adhesive layer. In the process of film application, the user first tears off the first release layer, aligns the protective layer with the display screen, and allows the protective layer to be adhered to the display screen through the first adhesive layer. Finally, the second release layer is torn off the protective layer to complete the film application operation.

[0004] Since the second release layer is adhered to the protective layer through the second adhesive layer, when peeling the second release layer from the protective layer, the user needs a large force to peel the second release layer from the protective layer. However, the large force can easily peel the protective layer that has been adhered to the display screen off the display screen through the second release layer, thereby causing the film application operation to fail.

[0015] Furthermore, the second part is located at one end of the first part, or the first part is divided into two parts and the first part is located at both ends of the second part, or the first part is arranged around the second part, or the second part is arranged around the first part.

[0016] Further, in the width direction of the release layer, the width of the second portion is greater than 1 / 3 of the width of the release layer, and the width of the second portion is less than 1 / 2 of the width of the release layer.

[0017] Furthermore, in the length direction of the release layer, the length of the portion where the second portion covers the protective layer is not less than 1 / 6 of the length of the release layer.

[0018] Furthermore, part of the isolation layer extends beyond the edge of the protection layer.

[0030] Please refer to the attached Figure 1-3 , an embodiment of the utility model provides an electronic device protective film, including a protective layer 10, including the protective layer 10 and a release layer 20 arranged on one side of the protective layer 10, the release layer 20 includes a first part 30 and a second part 40, the release layer 20 is connected to the protective layer 10 through the first part 30, the second part 40 is overlapped at a corresponding position of the protective layer 10, and the second part 40 is not connected to the overlapping part of the protective layer 10. It can be explained that the second part 40 is overlapped at a corresponding position of the protective layer 10 to form an overlapping part, and the overlapping part is not connected to the second part 40, that is, there is no connection force between the overlapping part and the second part 40.

[0031] It should be further explained that the protective layer 10 includes a bonding surface 101 for bonding with the display screen and a protective surface 102 facing away from the bonding surface 101. The protective layer 10 can be a tempered layer or a hydraulic layer. The protective layer 10 is provided with a release layer 20 on one side of the protective surface 102. Optionally, the area of ​​the first portion 30 is greater than the area of ​​the second portion 40.

[0032] In this embodiment, a first portion 30 and a second portion 40 are arranged on the release layer 20, wherein the first portion 30 is connected to the protective layer 10, and the second portion 40 is overlapped at a corresponding position of the protective layer 10 and is not connected to the overlapped portion of the protective layer 10. This ensures that the release layer 20 can completely cover the protective surface 102 to protect the protective layer 10 before the protective film is attached, and at the same time, the connection force between the release layer 20 and the protective surface 102 can be reduced, so that when the user peels the release layer 20 off the protective surface 102, the arrangement of the second portion 40 can make it easier for the release layer 20 to be peeled off from the protective surface 102. In this process, the user only needs a small force to peel the release layer 20 off the protective surface 102, thereby reducing the risk of peeling off the protective layer 10 that has been adhered to the display screen from the display screen when peeling off the release layer 20.

[0033] In an optional embodiment, the first part 30 is in contact with and connected to the protective layer 10, and the second part 40 is spaced apart from the protective layer 10. In a specific example, the first part 30 and the protective layer 10 can be tightly connected by magnetic adhesion. Figure 4 The electronic device protective film further includes an isolation layer 60 , which is disposed between the second portion 40 and the protective layer 10 , so that the second portion 40 and the protective layer 10 are spaced apart.

[0034] In an optional embodiment, the isolation layer 60 is connected to the second part 40, and the isolation layer 60 is not connected to the protective layer 10. When the release layer 20 is peeled off, the isolation layer 60 is peeled off from the protective layer 10 together with the second part 40. In another optional embodiment, the isolation layer 60 is connected to the protective layer 10, and the isolation layer 60 is not connected to the second part 40. When the release layer 20 is peeled off, the second part 40 is first peeled off from the isolation layer 60, and then the isolation layer 60 is peeled off from the protective layer 10 separately.

[0035] In an optional embodiment, the electronic device protective film further includes an adhesive layer, which is disposed between the first portion 30 and the protective layer 10, and the first portion 30 is connected to the protective layer 10 through the adhesive layer. It should be further explained that the first portion 30 and the protective surface 102 are connected through the adhesive layer. Specifically, the adhesive layer can be formed by coating an adhesive on the first portion 30. Optionally, the second portion 40 is not coated with an adhesive, has no adhesiveness, and is not adhered to the protective surface 102 through an adhesive. It can be explained that when the first portion 30 is coated with an adhesive, the second portion 40 should be avoided so that the second portion 40 maintains the original surface state of the release layer 20. Further optionally, the electronic device protective film further includes an isolation layer 60, which is disposed between the second portion 40 and the protective layer 10 so that the second portion 40 and the protective layer 10 are spaced apart. In a specific example, the isolation layer 60 is connected to the second part 40, and the isolation layer 60 is not connected to the protective layer 10. It can be explained that the second part 40 is also coated with adhesive, and the isolation layer 60 is connected to the second part 40 through the adhesive. The side of the isolation layer 60 facing the protective surface 102 is not coated with adhesive, has no adhesiveness, and is not adhered to the protective surface 102 through the adhesive, that is, the adhesive layer covers the first part 30 and the second part 40, and the isolation layer 60 is connected to the side of the adhesive layer away from the second part 40, and the isolation layer 60 is not connected to the protective layer 10.

[0036] In another optional embodiment, the isolation layer 60 is connected to the protective layer 10, and the isolation layer 60 is not connected to the second part 40. It can be explained that the side of the isolation layer 60 facing the protective surface 102 is coated with adhesive, and the isolation layer 60 is connected to the protective layer 10 through the adhesive, and the side of the isolation layer 60 facing the second part 40 is not coated with adhesive, has no adhesiveness, and is not adhered to the second part 40 through the adhesive. The adhesive can usually be selected from an adhesive with relatively low adhesive properties, such as acrylic acid, and its coating thickness is relatively thin, so that the user can relatively easily peel off the release layer 20 on the protective surface 102 after the protective layer 10 is attached to the display screen.

[0037] It is further explained that the bonding surface 101 is coated with a high-viscosity adhesive, which has a high adhesion and is thicker than the first part 30, so that the protective layer 10 can be firmly attached to the display screen, ensuring the firmness and stability of the bonding, and preventing the protective layer 10 from falling off or loosening. The type of high-viscosity adhesive can be one of silicone and AB glue. The bonding surface 101 is provided with a protective layer 50 on the side where the adhesive is coated. The protective layer 50 is used to cover the adhesive on the bonding surface 101, protect the bonding surface 101 before the protective film is attached, and prevent the bonding surface 101 from being contaminated by dust, fingerprints or other dirt.

[0038] The process of applying the protective film for the electronic device provided in this embodiment is as follows:

[0039] Before starting to apply the film, make sure the display screen is clean and dust-free. You can use a special cleaning cloth or detergent to wipe the display screen to ensure that the surface is clean; tear off the protective layer 50 on the side of the protective layer 10 on the bonding surface 101, align the bonding surface 101 with the display screen, align the edges and openings to ensure accurate bonding; starting from one side of the protective film, slowly adhere the bonding layer to the display screen, and at the same time gently press the surface of the release layer 20 with your fingers to make the protective layer 10 stick evenly to the display screen; tear off the release layer 20 from the protective surface 102 to complete the film application operation.

[0040] The electronic device protective film provided in this embodiment can be applied to the display screen protection of mobile phones, tablet computers or other electronic devices. Exemplarily, the electronic device protective film is applied to mobile phones, that is, a mobile phone protective film, and the shape of the mobile phone protective film is usually rectangular, corresponding to the shape of the mobile phone display screen. Some mobile phone protective films also have special functions, such as anti-glare, anti-fingerprint, anti-blue light, anti-shattering, etc. These special functions can vary according to user needs and manufacturer's design.

[0041] In an optional embodiment, the second portion 40 is located at one end of the first portion 30, which can be explained as the second portion 40 being located at the edge of the release layer 20. The number of the first portion 30 can also be two, and the first portion 30 is located at both ends of the second portion 40, which can be explained as the second portion 40 being located between the two first portions 30. The second portion 40 is formed as an initial separation zone between the release layer 20 and the protective layer 10 when the release layer 20 is peeled off.

[0042] In another optional embodiment, the first portion 30 is disposed around the second portion 40 , or the second portion 40 is disposed around the first portion 30 .

[0043] In an optional embodiment, the second portion 40 is disposed in a partial width direction of the release layer 20. It can be explained that the release layer 20 includes a first width and a second width disposed opposite to the first width, and the second portion 40 can be disposed on one of the first width and the second width, or can be disposed on both the first width and the second width. In this embodiment, by disposing the second portion 40 in a partial width direction of the release layer 20, the release layer 20 is easier to tear off, the difficulty of tearing off is reduced, and the risk of the bonding layer being torn off from the display screen is reduced. The reason is that the length of the release layer 20 in the width direction is shorter, and when the user applies a tearing force, the effective area is smaller, making the release layer 20 easier to tear off.

[0044] In an optional embodiment, the second portion 40 is disposed in the middle of the width direction of the release layer 20. By disposing the second portion 40 in the middle of the width direction of the release layer 20, it can be ensured that both sides of the release layer 20 have a certain first portion 30, and the widths of the first portions 30 on both sides are equal. When the user applies a tearing force to the second portion 40, the tearing force can be evenly transferred to the first portions 30 on both sides, so that the release layer 20 as a whole can be torn off more conveniently. It can be explained that the release layer 20 also includes a positioning end 201, which is used to help the user accurately align and position the protective film with the display screen when attaching the protective film to avoid the protective film from being offset or skewed.

[0045] In an optional embodiment, in the width direction of the release layer 20 , the width of the second portion 40 is greater than 1 / 3 of the width of the release layer 20 , and the width of the second portion 40 is less than 1 / 2 of the width of the release layer 20 .

[0046] In this embodiment, by limiting the width of the second part 40 to between 1 / 3 and 1 / 2 of the width of the release layer 20, the release layer 20 can be easily peeled off while ensuring the connection stability. If the second part 40 is too wide, the area of ​​the second part 40 is too large, and the area of ​​the first part 30 is too small, the release layer 20 may be accidentally separated from the protective surface 102 before the protective film is attached, causing the protective surface 102 to leak out or even be damaged. Therefore, in order to prevent this from happening, the width of the second part 40 needs to be controlled within an appropriate range of the width of the release layer 20 to ensure the connection stability between the release layer 20 and the protective surface 102. On the other hand, if the second part 40 is too narrow, the area of ​​the second part 40 is too small, and the area of ​​the first part 30 is too large, the protective film may need to use a lot of force to peel off the release layer 20 from the protective surface 102 when attaching, and if the tearing force is too large, the protective layer 10 attached to the display screen may be torn off from the display screen, resulting in film attachment failure. Therefore, the width of the second portion 40 needs to be controlled within an appropriate range to ensure that the release layer 20 can be easily peeled off from the protective surface 102 .

[0047] In an optional embodiment, in the length direction of the release layer 20, the length of the portion of the second portion 40 covering the protective layer 10 is not less than 1 / 6 of the length of the release layer 20. The length of the portion of the second portion 40 covering the protective layer 10 also affects the ease of peeling the release layer 20 from the protective surface 102. In order to enable the user to easily peel the release layer 20 from the protective surface 102 without too much effort, the length of the portion of the second portion 40 covering the protective layer 10 is not less than 1 / 6 of the length of the release layer 20.

[0048] In an optional embodiment, the number of the second part 40 can be multiple. Specifically, multiple second parts 40 are arranged in the width direction of the release layer 20, or multiple second parts 40 are arranged in the length direction of the release layer 20. By providing multiple second parts 40 on the release layer 20, a more convenient peeling operation of the release layer 20 can be provided, thereby improving the user experience. The specific arrangement of the second part 40 can be adjusted according to the design of the protective film and user needs.

[0049] In a specific example, the second portion 40 can be disposed near the positioning end 201 of the release layer 20. The positioning end 201 refers to one or more edges of the release layer 20, which are used to position and align the display screen. Placing the second portion 40 near the positioning end 201 can facilitate the user to find a suitable position when peeling off the release layer 20, and will not affect the alignment of the release layer 20 with the protective surface 102.

[0050] Please see attached Figure 5In an optional embodiment, part of the isolation layer 60 extends outside the edge of the protective layer 10. Specifically, the isolation layer 60 includes a main body 601 and a protruding portion 602, wherein the main body 601 is disposed at the edge of the release layer 20, and the protruding portion 602 protrudes outside the edge of the release layer 20. The main body 601 and the protruding portion 602 are integrally connected, and the width of the protruding portion 602 may be greater than the width of the main body 601, so that the user can more easily grasp the protruding portion 602 when peeling off the release layer 20, thereby easily peeling off the release layer 20 from the protective surface 102. When the user needs to peel off the release layer 20, the user can first peel off the release layer 20 from the main body 601 by holding the protruding portion 602, and then gradually peel off the entire release layer 20, so that the peeling off of the release layer 20 is easier and more convenient, and avoids peeling off the bonding layer that has been attached to the display screen. Specifically, the isolation layer 60 is a film or other material attached to the release layer 20 .

[0051] In an optional embodiment, the isolation layer 60 is formed by extending outward from the positioning end 201 of the release layer 20 and bending toward the protective surface 102; specifically, the isolation layer 60 and the release layer 20 are an integral structure, the isolation layer 60 and the positioning end 201 are connected by a fold, and the isolation layer 60 is sandwiched between the release layer 20 and the protective surface 102. In another optional embodiment, the isolation layer 60 is an independent film layer independently provided relative to the release layer 20.

[0052] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
