Description

Technical Field

[0001] The present disclosure relates to the technical field of equipment production, and in particular to a protective film. Background Art

[0002] During the production of various electronic devices, dust or moisture may fall onto some components during the process of unpacking and assembling them with other parts, causing them to deteriorate. Therefore, protective films are necessary to provide some protection for these components. For example, in the production of devices with a screen and a front-facing camera, since the screen has an opening corresponding to the front-facing camera, this opening is prone to dust accumulation. Therefore, a protective film can be placed at the corresponding position on the midframe to prevent dust from falling onto the screen or into the opening.

[0003] In the related art, after the protective film is attached to the target structure (such as the middle frame), there is a need to tear off the protective film during subsequent production. Therefore, a portion of the protective film is generally left unattached to the target structure.

[0004] However, the portion that is not adhered to the target structure is prone to interfere with some protruding structures on the target structure, so that the protective film is easily fallen off during the transfer or transportation of the target structure, resulting in poor dust protection effect. Utility Model Content

[0005] In view of this, the present disclosure provides a protective film that is not easy to fall off and has a good dustproof protection effect.

[0006] Specifically, the following technical solutions are included:

[0007] The present disclosure provides a protective film comprising a first film layer and a second film layer.

[0008] The first film layer comprises a first surface and a second surface opposite to each other, and the first surface has adhesive force or adsorption force;

[0009] The second film layer includes a first portion and a second portion, wherein the first portion is connected to the second surface, the second portion is separated from the second surface, and the second portion extends to an edge of the second film layer.

[0018] Optionally, the bending area is in the shape of a long strip or a line.

[0019] Optionally, a line connecting the center of the handle and the center of the bending zone is perpendicular to an extension direction of the bending zone.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present disclosure.

[0041] The positional nouns involved in the embodiments of the present disclosure, such as “upper”, “lower”, “lateral”, etc., are generally based on the positions shown in the drawings or the relative positional relationship between structures when the protective film is placed in the usual manner, and the use of these positional nouns is only for a clearer description of the structures and the relationship between the structures, and is not intended to describe absolute positions. When the protective film is placed in different postures, the positions may change, for example, “upper” and “lower” may be interchanged.

[0042] Unless otherwise defined, all technical terms used in the embodiments of the present disclosure have the same meanings as commonly understood by those skilled in the art.

[0043] In order to make the technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be described in further detail below in combination with the drawings.

[0044] The embodiments of the present disclosure provide a protective film. Figure 1-4 A structural schematic diagram of the protective film arranged on a target structure is given.

[0045] Reference Figure 1-4 The protective film 1 includes a first film layer 11 and a second film layer 12,

[0046] The first film layer 11 includes opposite first and second surfaces 111 and 112, and the first surface 111 has adhesive or adsorptive force;

[0047] The second film layer 12 includes a first part 121 and a second part 122, the first part 121 is connected to the second surface 112, the second part 122 is separated from the second surface 112, and the second part 122 extends to the edge of the second film layer 12.

[0048] The embodiment of the present disclosure provides a protective film, which includes a first film layer and a second film layer. The first surface of the first film layer has an adhesive force or an adsorption force, and is suitable for adhering or adsorbing on the surface of a target structure to be protected or the surface of a device arranged opposite to the target structure to achieve dustproof protection; the second surface of the first film layer is connected to the first part of the second film layer and separated from the second part of the second film layer. Then, when the protective film needs to be torn off, the user can directly operate by hand to make the second part of the second film layer tilt relative to the first film layer, and then drag the tilted part so that the first film layer is pulled away from the target structure by the first part of the second film layer, thereby achieving the removal of the entire protective film. In this way, the first film layer can effectively protect the target structure, and at the same time, because the first film layer will not interfere with other structures, the protective film is not easy to fall off; in addition, the protective film is torn off with the help of the second film layer, so that the tearing efficiency of the protective film is high.

[0049] It should be noted that the aforementioned "adhesive force" can be achieved by pre-preparing a colloid on the first surface of the first film layer. The aforementioned "adhesive force" can be achieved by appropriately selecting the material and preparation process of the first film layer to impart a certain adsorption force to the first surface of the first film layer, such as electrostatic adsorption. The first surface of the first film layer can be directly attached to the target structure or attached to the foam structure 2 on the target structure.

[0050] In some embodiments, the first film layer 11 and the second film layer 12 are integrated; or,

[0051] The first film layer 11 and the second film layer 12 are two independent film layers, and the first portion 121 of the second film layer 12 is bonded or adsorbed to the second surface 112 of the first film layer 11 .

[0052] In this embodiment, when the first film layer and the second film layer are integrated, it can be ensured that when the user tears the second film layer, the pulling effect on the first film layer is more significant, and it is less likely that the connection between the second film layer and the first film layer will break. When the first film layer and the second film layer are two independent film layers, and the first part of the second film layer is bonded or adsorbed to the second surface of the first film layer, the first film layer and the second film layer can be prepared separately, and the preparation process of both is relatively simple and the cost is low. It should be noted that the adsorption here refers to the adsorption force between the second surface of the first film layer and the first part of the second film layer, and they are stably adsorbed together. When the first surface of the first film layer is attached to the target structure by means of the adsorption force, the adsorption force between the second surface of the first film layer and the first part of the second film layer should be greater than the adsorption force between the first surface of the first film layer and the target structure, so as to ensure that the protective film can be torn off later.

[0053] Optional, reference Figure 1The protective film 1 comprises a first adhesive layer 13, and the second surface 112 of the first film layer 11 and the first part 121 of the second film layer 12 are adhered together through the first adhesive layer 13.

[0054] With the first adhesive layer, the connection stability between the first film layer and the second film layer can be more effectively ensured, and the convenience and efficiency of tearing off the protective film later can be ensured.

[0055] In some embodiments, referring to Figure 1-4 The protective film 1 further comprises a handle 14, and the handle 14 is connected to the second part 122 of the second film layer 12.

[0056] Based on the above arrangement, when it is necessary to tear off the protective film, the user pulls the handle to drive the second part of the second film layer, the second part of the second film layer drives the first part, the first part is connected to the first film layer, so the first part can drive the first film layer, and thus the tearing off of the whole protective film is realized. In this process, since the second part of the second film layer is separated from the first film layer, when the user pulls the handle, the handle is more easily driven to drive the whole second film layer and the first film layer through the second part, and the efficiency of tearing off the protective film is improved. That is, the user can more conveniently and quickly tear off the protective film.

[0057] Optionally, referring to Figure 1-2 The handle 14 protrudes relative to the second film layer 12. In this way, the user can more conveniently hold the handle, which is very advantageous for a smaller space.

[0058] Optionally, referring to Figure 1-2 The handle 14 is connected to the edge of the second part 122 away from the first part 121. In this way, the handle 14 is more easily held by the user, and the force of the user on the handle can be more evenly transmitted to the first part, and thus the efficiency of tearing off the protective film is improved.

[0059] Optionally, referring to Figure 2-4 The second part 122 and the handle 14 can be bent relative to the first part 121.

[0060] Based on the above arrangement, on the one hand, when the user pulls the handle, the user can adjust the force direction according to the trend of the surrounding space, which is convenient for the user to operate. On the other hand, when there are some protruding structures (such as the protruding structure 3 marked in Figure 1-4 the target structure, the second part of the second film layer and the handle can change their positions and states according to the morphology of the surrounding structure, and this process will not affect the state of the first part of the second film layer and the first film layer, and thus will not cause the protective film to fall off, and the long-term protection effect of the protective film on the target structure can be ensured.

[0061] Optionally, referring to Figure 1-4 , the second film layer 12 further comprises a bending area 123, the bending area 123 is connected between the first part 121 and the second part 122, when the second part 122 is bent relative to the first part 121, the bending area 123 is bent.

[0062] By setting the bending area, the position change or state change of the second part relative to the handle can be more effectively ensured, without causing too much influence on the first part of the second film layer, and further without affecting the attaching effect between the protective film and the target structure.

[0063] Optionally, referring to Figure 2 and 4 , the bending area 123 is in a strip shape or a line shape.

[0064] When the width of the bending area is small, the shape thereof is similar to a line shape. In implementation, the bending area can be made by a tool in the process of cutting the protective film, for example, can be formed in the form of a knife mark line or a similar whipstitch line.

[0065] Optionally, referring to Figure 2 , the line connecting the center of the handle 14 and the center of the bending area 123 is perpendicular to the extension direction of the bending area 123.

[0066] In this way, when the user exerts force on the handle, the handle can more directly and effectively conduct the force to the first part through the second part and the bending area, so that the first part can more efficiently drive the first film layer to remove the protective film.

[0067] Optionally, the handle 14 and the second film layer 12 are integrally formed. In this way, the generation efficiency of the protective film can be further improved.

[0068] In some embodiments, the handle 14 is in a rectangular shape, a circular shape, a trapezoidal shape, a triangular shape, a square shape, a sector shape, a ring shape, a polygon with more than four sides, or a special shape. Here, the special shape refers to an irregular shape, for example, a concave polygon or a star shape, etc. In specific applications, the shape of the handle can be designed according to the shape of the surrounding space and other factors, which are not limited in the present application.

[0069] In some embodiments, referring to Figure 2 , the area of the first part 121 is equal to or different from the area of the second part 122.

[0070] In this embodiment, the area ratio between the first and second portions is actually related to the pulling force exerted by the second film layer on the first film layer. When the area of ​​the first portion is larger and the area of ​​the second portion is smaller, the pulling force exerted by the second film layer on the first film layer is greater. When the area of ​​the first portion is smaller and the area of ​​the second portion is larger, the pulling force exerted by the second film layer on the first film layer is smaller. The desired pulling effect can be achieved by setting the areas of the first and second portions to be equal or different.

[0071] Optionally, when the areas of the first portion 121 and the second portion 122 are not equal, the first portion 121 accounts for one-third or more of the area of ​​the second film layer 12. This ensures that the pulling force of the second film layer on the first film layer is not too weak, ensuring that the first film layer can be separated from the target structure when the user pulls the second film layer.

[0072] In some embodiments, the protective film 1 is in the shape of a rectangle, circle, trapezoid, triangle, square, polygon with more than four sides, or a special shape, wherein the special shape refers to an unconventional shape, such as a concave polygon or a star.

[0073] In this embodiment, the shape of the protective film can be adjusted as needed. The shape of the protective film can be adjusted to match the shape of the target structure to be protected. The figures in this disclosure illustrate the protective film as a circular shape.

[0074] The protective film provided by the embodiment of the present disclosure can, for example, be used to be attached to the position corresponding to the front camera on the middle frame of the device to provide dust protection for the opening (for installing the front camera) on the screen that is unpacked and installed in the middle frame.

[0075] In summary, the present disclosure provides a protective film that can protect the target structure from dust, while not interfering with surrounding components and not easily falling off; and can also be removed efficiently and conveniently.

[0076] In the present disclosure, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless expressly limited otherwise.

[0077] Other embodiments of the present disclosure will readily occur to those skilled in the art after considering the specification and practicing the present disclosure disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein.
