Background
In the process of producing or transporting electronic devices, it is generally necessary to protect the fragile surfaces of the electronic devices to prevent the surfaces of the electronic devices from being damaged by friction or scratching. At present, electronic equipment is protected by sticking a protective film on the surface of the electronic equipment. However, in order to ensure the protective effect of the protective film on the surface of the electronic device and prevent the protective film from being separated from the surface of the electronic device by itself due to insufficient adhesion during production or transportation, the adhesion between the protective film and the surface of the electronic device is usually strong, which makes the process of removing the protective film difficult.
SUMMERY OF THE UTILITY MODEL
Accordingly, it is desirable to provide a film structure and an electronic device, which solve the problem of difficulty in removing a protective film.
A film structure for application to a surface of an object, said film structure comprising:
the film body is provided with a pasting surface, the pasting surface is used for being pasted on the surface of the pasted object in a bonding mode, and one end of the pasting surface is a tearing end; and
the reverse pasting piece is arranged on the pasting surface and is positioned at the tearing-starting end of the pasting surface, the reverse pasting piece comprises a reverse pasting surface and a bonding surface which are oppositely arranged, the reverse pasting surface faces the pasting surface and is bonded with the pasting surface, the bonding surface faces the surface of the pasted object and is used for bonding the surface of the pasted object, and the viscosity between the reverse pasting surface and the pasting surface is greater than the viscosity between the bonding surface and the surface of the pasted object.
In the film structure, the reverse attaching piece is arranged at one end of the attaching surface to form the tearing start end of the film structure, and because the viscosity between the reverse attaching surface and the attaching surface is greater than the viscosity between the bonding surface and the surface of the attached object, the film structure can be torn off from the surface of the attached object by taking the tearing start end as a starting point more easily. Therefore, the adhesion effect between the attaching surface and the surface of the attached object is ensured, so that the film structure can be torn off more easily while the protective effect of the film structure on the surface of the attached object is ensured.
In one embodiment, the shape of the attaching face is rectangular, and the tearing start end is one corner of the attaching face. According to the different shapes of the surfaces of the objects to be pasted, the shapes of the pasting surfaces can be selected differently, so that the film structure can better cover the surfaces of the objects to be pasted.
In one embodiment, the two adjacent edges of the reverse attaching faces are respectively flush with the two adjacent edges of the attaching faces. In this way, the reverse sticker is better covered on the tearing end, and the membrane structure is easier to tear.
In one embodiment, the shape of the facing is rectangular or triangular. The varied shape allows more options for the design of the reverse side.
In one embodiment, when the shape of the reverse facing surface is a triangle, the shape of the reverse facing surface is a right triangle, two right-angle sides of the reverse facing surface respectively correspond to two adjacent sides of the facing surface one by one, each right-angle side of the reverse facing surface is flush with the corresponding side of one of the facing surfaces, and the length ratio of each right-angle side of the reverse facing surface to the corresponding side of one of the facing surfaces is 1/5-1/20. Thus, the anti-sticking piece can better cover the tearing end and is more attractive.
In one embodiment, the peel strength between the bonding surface and the surface of the attached object is less than half of the peel strength between the covering surface and the surface of the attached object. Therefore, the film structure can be further ensured to be easier to tear off while the protective effect of the film body on the surface of the attached object is ensured.
In one embodiment, the peel strength between the bonding surface and the surface of the attached object is between 5g/cm and 10 g/cm. In this case, the peel strength between the adhesive surface and the surface of the adherend is small, and the film structure can be easily peeled.
In one embodiment, the attaching surface and the bonding surface are both covered with glue, and the attaching surface and the bonding surface are attached to the surface of the attached object through the glue. The adhesive is convenient to operate, and can save the production cost.
In one embodiment, powder is distributed in the glue on the bonding surface to reduce the viscosity between the bonding surface and the surface of the attached object. The powder is used for controlling the viscosity between the bonding surface and the surface of the attached object, so that the operation is more convenient, and the production cost can be saved.
An electronic device comprises a body and the film structure of any of the above embodiments, wherein the film structure is attached to the surface of the body.

Referring to fig. 1 and 2, a film structure 100 is applied to a surface of an object 200 to prevent the surface of the object 200 from being damaged by friction or scratching. Specifically, the film structure 100 comprises a film body 110, the film body 110 is provided with an attaching face 111, the attaching face 111 of the film body 110 faces the surface of the attached object 200 in use, and the film body 110 moves towards the surface of the attached object 200 along the direction of the dotted arrow in fig. 1 until the attaching face 111 is adhered to the surface of the attached object 200. Moreover, the film structure 100 further includes a reverse-attaching member 120, and when the film body 110 is attached to the surface of the attached object 200, the reverse-attaching member 120 is disposed between the film body 110 and the attached object 200 and located at one end of the film body 110. More specifically, the reverse patch 120 includes a reverse patch surface 121 and an adhesive surface 122 disposed oppositely. When the film body 110 is attached to the surface of the attached object 200, the reverse attaching surface 121 faces the attaching surface 111 and is adhered to the attaching surface 111 at one end of the attaching surface 111, and the bonding surface 122 faces the surface of the attached object 200 and is adhered to the surface of the attached object 200. Further, the adhesiveness between the reverse attaching surface 121 and the attaching surface 111 is larger than the adhesiveness between the adhesive surface 122 and the surface of the adherend 200.
Referring to fig. 1 and 2, it can be understood that, when the film structure 100 is attached to the surface of the adherend 200, since the adhesiveness between the reverse attaching surface 121 and the attaching surface 111 is greater than the adhesiveness between the adhesive surface 122 and the surface of the adherend 200, the film body 110 is more easily torn from the surface of the adherend 200 from the end of the film body 110 where the reverse attaching member 120 is provided, even if the adhesive surface 122 is separated from the surface of the adherend 200, as compared to the tearing of the film body 110 from the surface of the adherend 200 from the remaining end of the film body 110. Thus, the end provided with the reverse attachment member 120 forms a tear initiation end 130 that facilitates the tearing of the film structure 100 from the adherend 200.
Further, in order to avoid the situation that the film structure 100 is separated from the surface of the adherend 200 due to insufficient viscosity of the attaching surface 111 in the production or transportation process, the viscosity between the attaching surface 111 and the surface of the adherend 200 can be improved, so as to ensure the protection effect of the film structure 100 on the surface of the adherend 200. When the film structure 100 needs to be torn off from the surface of the adherend 200, the film structure 100 is torn off from the end of the film body 110 where the reverse attachment member 120 is disposed, i.e., the tear-off end 130, so that the adhesive surface 122 is separated from the surface of the adherend 200. Further, the tearing end 130 away from the surface of the adherend 200 is used as a stressed end, so that the rest of the film body 110 can be easily torn from the surface of the adherend 200, and the film structure 100 can be easily torn.
Therefore, the film structure 100 can ensure the adhesion effect between the attaching face 111 and the surface of the attached object 200, so as to ensure the protective effect of the film structure 100 on the surface of the attached object 200, and simultaneously, the film structure 100 can be easier to tear.
It should be understood that, in the present application, the film structure 100 can be torn off from the surface of the adherend 200 in an unlimited manner, for example, in some embodiments, a manual direct tearing off is adopted, and at this time, a finger nail of a human body can be inserted between the adhesive surface 122 and the surface of the adherend 200 to tear off the tear-off end 130 of the film structure 100. In other embodiments, the film structure 100 may be torn off by a manipulator, in which a tearing portion of the manipulator extends between the bonding surface 122 and the surface of the adherend 200 to tear off the tear-off end 130 of the film structure 100.
In addition, the sequence of the film body 110 and the reverse-attaching member 120 being attached to the surface of the object 200 is not limited, in some embodiments, the reverse-attaching member 120 may be attached to the film body 110 first, even if the reverse surface 121 is adhered to the attaching surface 111, and then the film body 110 is attached to the surface of the object 200, so that the attaching surface 111 is adhered to the surface of the object 200, and at this time, the bonding surface 122 is also adhered to the surface of the object 200 along with the film body 110. In other embodiments, the reverse-attaching member 120 may be attached to the surface of the attached object 200 first, i.e. the bonding surface 122 is bonded to the surface of the attached object 200, and then the film body 110 is attached to the surface of the attached object 200, and the portion of the attaching surface 111 located at the tearing end 130 is bonded to the reverse surface 121.
It should be noted that the coverage area of the film structure 100 on the surface of the adherend 200 is not limited, and may be specifically selected according to the area of the portion of the surface of the adherend 200 that needs to be protected. Specifically, in some embodiments, referring to fig. 2, the middle portion of the surface of the adherend 200 is provided with glass or other fragile objects, and in this case, the film structure 100 only needs to protect the middle portion of the surface of the adherend 200, and the film structure 100 may only cover the middle portion of the surface of the adherend 200. In other embodiments, the object 200 may also be a rear cover of a smart phone, in which case, the entire surface of the object 200 needs to be protected to prevent the surface of the object 200 from being scratched, and the film structure 100 may cover the entire surface of the object 200.
In addition, the shape of the film structure 100 covering the surface of the object 200, that is, the projection of the film structure 100 on the surface of the object 200, may be selected according to the shape of the region of the surface of the object 200 to be protected. In some embodiments, the film body 110 and the reverse-attaching member 120 are both thin film structures, and the shape of the attaching surface 111 can be regarded as the covering shape of the film structure 100 on the surface of the attached object 200. Specifically, in some embodiments, the area of the surface of the attached object 200 to be protected is rectangular, and the shape of the attaching surface 111 is set to be rectangular accordingly, so as to better cover the area of the surface of the attached object 200 to be protected, and to better protect the surface of the attached object 200. Of course, in other embodiments, the shape of the application surface 111 may also be any suitable shape such as circular, triangular, etc. It is understood that the tear initiation end 130 can be one of the corners of the attachment surface 111 when the attachment surface 111 is rectangular or triangular in shape, and the tear initiation end 130 can be one of the portions of the attachment surface 111 near the edge region when the attachment surface 111 is circular in shape.
Further, the shape of the reverse patch 120 is not limited, and in some embodiments, the shape of the reverse patch 120 may be rectangular, triangular, or circular. Also, referring to fig. 3 and 4 together, in some embodiments, two adjacent edges of the reverse attaching surface 121 are flush with two adjacent edges of the attaching surface 111, respectively. Specifically, referring to fig. 3, in some embodiments, the pasting surface 111 is rectangular, and the reverse pasting surface 121 is also rectangular, and at this time, two adjacent edges of the reverse pasting surface 121 are flush with two adjacent edges of the pasting surface 111. In other embodiments, as shown in fig. 4, the attaching surface 111 is rectangular, and the reverse surface 121 is right-angled triangle, in which case, two right-angled sides of the reverse surface 121 correspond to two adjacent sides of the attaching surface 111 one by one, each right-angled side of the reverse surface 121 is flush with a corresponding side of one of the attaching surfaces 111, and the length ratio of each right-angled side of the reverse surface 121 to the corresponding side of one of the attaching surfaces is 1/5-1/20. Thereby, the reverse facing 121 can more completely cover the portion of the facing 111 at the tear initiation end 130 to ensure that the film structure 100 can be more easily torn from the tear initiation end 130 portion. It should be noted that, in some embodiments, the reverse attachment member 120 is a film structure, and at this time, the projection of the reverse attachment surface 121 and the projection of the bonding surface 122 on the attachment surface 111 coincide with each other, that is, when two adjacent edges of the reverse attachment surface 121 are respectively flush with two adjacent edges of the attachment surface 111, two adjacent edges of the bonding surface 122 are also flush with two adjacent edges of the attachment surface 111.
In addition, in the present application, when the tackiness of a certain surface is described, the magnitude of the tackiness of the surface itself is understood, and when the magnitude of the tackiness between two surfaces is described, the magnitude of the adhesion force between the two surfaces is understood. It is understood that the adhesion between the attaching surface 111 and the surface of the attached object 200 does not necessarily mean that the attaching surface 111 has adhesiveness, and it is also possible that the surface of the attached object 200 has adhesiveness, so that the attaching surface 111 adheres to the surface of the attached object 200. Of course, in some embodiments, the surface of the attachment surface 111 and the surface of the adherend 200 may have adhesiveness, so as to ensure that the attachment surface 111 is the surface of the adherend 200 and has better adhesion effect. Similarly, in some embodiments, the reverse facing surface 121 and the attachment facing surface 111 are adhered, either one of the reverse facing surface 121 and the attachment facing surface 111 has adhesiveness, or both the reverse facing surface 121 and the attachment facing surface 111 have adhesiveness. The adhesive surface 122 is adhered to the surface of the object 200, and either the adhesive surface 122 or the surface of the object 200 may have adhesiveness, or both the adhesive surface 122 and the surface of the object 200 may have adhesiveness. Specifically, the adhesion between the back surface 121 and the attaching surface 111 is ensured to be greater than the adhesion between the bonding surface 122 and the surface of the attached object 200. Thus, it can be ensured that the film structure 100 can be easily torn from the surface of the adherend 200 by the tearing end 130, and the reverse attachment member 120 can be ensured not to be separated from the film body 110 and remain on the surface of the adherend 200 during the tearing process.
Specifically, in some embodiments, the attaching surface 111 and the bonding surface 122 are covered with glue, so that the attaching surface 111 and the bonding surface 122 have adhesiveness, so as to enable the surfaces of the attaching surface 111 and the adherend 200, the attaching surface 111 and the reverse attaching surface 121, and the bonding surface 122 and the surface of the adherend 200 to be adhered. The adhesive is adopted to make the pasting surface 111 and the bonding surface 122 have viscosity, the operation is simple and convenient, and the production cost is low. Further, in some embodiments, after the adhesive surface 122 is covered with glue, the adhesive surface 122 is covered with powder, so that the powder is distributed in the glue, the viscosity of the glue is reduced, and further the viscosity of the adhesive surface 122 is reduced, so that the effect that the viscosity between the reverse attaching surface 121 and the attaching surface 111 is greater than the viscosity between the adhesive surface 122 and the surface of the attached object 200 is achieved. It should be noted that the powder covered on the bonding surface 122 cannot have viscosity itself, and cannot react with the glue to generate viscosity, so as to avoid the situation that the powder increases the viscosity of the bonding surface 122. More specifically, in some embodiments, the bonding surface 122 may be covered with a non-adhesive mineral powder.
Further, in some embodiments, the peel strength between the adhesive surface 122 and the surface of the adherend 200 is less than half of the peel strength between the facing surface 111 and the surface of the adherend 200. Specifically, in some embodiments, the peel strength between the adhesive surface 122 and the surface of the adherend 200 is between 5g/cm and 10g/cm, and in this case, the reverse sticker 120 may be an ultra-low-viscosity film, so that the adhesive surface 122 is more easily separated from the surface of the adherend 200, and the film structure 100 is easier to tear. The peel strength between the attaching surface 111 and the surface of the attached object 200 is 10g/cm-50g/cm, which can ensure that the film body 110 is not easy to separate from the surface of the attached object 200, and further ensure the protection effect of the film structure 100 on the surface of the attached object 200.
The material of the film body 110 and the backing material 120 is not limited as long as the surface of the adherend 200 can be protected. For example, the film body 110 may be made of any material such as polypropylene or polyester. In some embodiments, the reverse attaching member 120 is made of Polyethylene (PE) or Polyethylene terephthalate (PET). It should be noted that, in the present application, when the film body 110 and the backing member 120 are film-layer structures, it does not mean that the film body 110 and the backing member 120 are only single-layer film structures, and may also be multi-layer film structures. For example, in some embodiments, the film body 110 has a three-layer film structure including an absorption layer, an intermediate layer, and an anti-glare layer, wherein the absorption layer is close to the surface of the adherend 200, and the anti-glare layer is disposed on a layer of the intermediate layer facing away from the surface of the adherend 200. The multi-layer film structure enables the film body 110 to have more protection effects on the surface of the adherend 200, such as anti-glare effect.
Further, referring to fig. 5, in some embodiments, the film structure 100 may be used in an electronic device 300, where the electronic device 300 includes a body 310, and the film structure 100 is attached to a surface of the body 310 to protect the surface of the body 310. Specifically, the electronic device 300 may be a smart phone, a laptop computer, a tablet computer, a camera, and the like. More specifically, when the electronic device 300 is a laptop computer, the main body 310 may be a cover portion of the electronic device 300, and the film structure 100 is attached to an outer surface of the main body 310 to prevent the outer surface of the main body 310 from being damaged by scratching and rubbing during transportation or production. When the electronic device 300 is a mobile phone, the body 310 may be a rear cover portion of the electronic device 300. In the electronic device 300, the film structure 100 is adopted, so that the film structure 100 can be more easily torn from the surface of the body 310 while the protective effect of the film structure 100 on the surface of the body 310 is ensured.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
