Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic device accessories, specifically to a protective film assembly and a film application device. Background Technology
[0002] To reduce screen scratches and prevent screen damage, people often apply screen protectors to mobile phones and other electronic devices. Screen protector application devices have emerged to address this need. Current screen protector application devices generally include a protective film and an applicator to assist in positioning and adhering the film. The applicator is usually a plastic case that fits over the phone. During application, to avoid affecting the use of the phone or other electronic devices after application, air bubbles are typically avoided between the screen protector and the device. However, since force is inevitably applied to the screen protector during application, and the film generally deforms under pressure, this deformation can easily create air bubbles that become trapped between the screen protector and the phone or other electronic devices, thus affecting their usability.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0034] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0035] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0036] It should also be noted that the division of multiple embodiments in this utility model is only for the convenience of description and should not constitute a special limitation. Features in various embodiments can be combined and referenced in each other without contradiction.
[0037] To reduce screen scratches and prevent screen damage, people usually apply screen protectors to electronic devices such as mobile phones. Taking mobile phones as an example, in current technology, to make it easy for users to apply the screen protector, it is usually positioned to align with the phone, allowing for precise application. However, during the positioning and application of the screen protector, it is unavoidable to apply force in different directions, causing deformation and making it difficult to adhere to the phone. This results in air bubbles not being completely expelled from between the screen protector and the phone.
[0038] Therefore, in order to solve the above-mentioned technical problems, such as Figure 1 As shown, this utility model provides a protective film assembly 70, including a protective film 10 and a first positioning film 20. The first positioning film 20 includes a positioning film main body 21 and a first positioning part 22 disposed at one end of the positioning film main body 21 along a first direction. The positioning film main body 21 is attached to the protective film 10. The first positioning part 22 extends away from the edge of the protective film 10. The first positioning part 22 has two first connecting parts 224 arranged along a second direction. The first connecting parts 224 are disposed at the end away from the positioning film main body 21. The dimension of the first positioning part 22 along the second direction is larger than that of the protective film 10. The first positioning part 22 has notches 221 on both sides along the second direction. The minimum distance of the notches 221 along the second direction is smaller than the dimension of the protective film along the second direction. The first direction and the second direction intersect.
[0039] The first positioning film 20 has a first positioning part 22 at one end along the first direction. The first positioning part 22 has two first connecting parts 224 arranged along the second direction. It is connected to the external structure through the first connecting parts 224, so that the first positioning film 20 can be positioned when applying the film, thereby positioning the protective film 10 attached to the main body 21 of the positioning film, so that it can be accurately applied to electronic devices such as mobile phones. Because the size of the first positioning part 22 along the second direction is larger than that of the protective film 10, that is, the distance between the two first connecting parts 224 along the second direction is larger than that of the protective film 10, the span of the first positioning part 22 along the second direction is larger than that of the protective film 10. Therefore, when the first positioning part 22 is positioned, it can provide a stretching force to the protective film 10 in the second direction to flatten the protective film 10 as a whole, and help the protective film 10 to remain stable during the application, making the application more accurate. Meanwhile, notches 221 are provided on both sides of the first positioning part 22 along the second direction, and the notches 221 are located on the side of the first positioning part 22 close to the positioning film body part 21. The minimum distance of the notches 221 along the second direction is smaller than the size of the protective film along the second direction, so that the size of the notches 221 of the first positioning part 22 along the second direction is smaller.
[0040] The principle of this utility model embodiment will now be explained in detail by applying a protective film assembly 70 to a mobile phone. The first positioning part 22 is connected to an external structure, aligning the protective film 10, which is attached to the positioning film body 21, with the mobile phone. During application, the protective film 10 is attached to the mobile phone from one end in the first direction. As the protective film 10 is attached to the mobile phone, a pulling force is generated on the positioning film body 21. Since the first positioning part 22 is still connected to the external structure, it also generates a pulling force on the positioning film body 21, thus stabilizing the entire protective film assembly 70. Due to the presence of the notch 221 on the first positioning part 22, and the fact that the minimum distance of the notch 221 along the second direction is less than the dimension of the protective film along the second direction, the dimension of the notch 221 in the first positioning part 22 along the second direction is less than the dimension of the protective film 10 along the second direction. Therefore, the component force along the second direction transmitted from the first positioning part 22 to the positioning film main body 21 is smaller than the component force along the second direction transmitted from the protective film 10 to the positioning film main body 21. This reduces the deformation of the positioning film main body 21 along the second direction, thereby reducing the component force along the second direction applied by the positioning film main body 21 to the protective film 10. Consequently, the deformation of the protective film 10 along the second direction on both sides near the notch 221 is reduced, without affecting the stretch received in the middle of the protective film 10. Therefore, the protective film 10 is easier to adhere to the mobile phone, reducing the possibility of air bubbles forming between the protective film 10 and the mobile phone. This further reduces the force applied to the protective film 10 along the thickness direction during application, making it more convenient for users. When the protective film 10 is nearly fully adhered, the force along the second direction on the positioning film body 21 is large, making it easier for the protective film 10 to deform along the second direction. However, since the notch 221 is provided, and the minimum distance of the notch 221 along the second direction is smaller than the size of the protective film along the second direction, when the protective film 10 is nearly fully adhered, the notch 221 also makes the force along the second direction on the positioning film body smaller than when it is not provided. This reduces the deformation of the protective film 10 along the second direction, making it easier for the protective film 10 to adhere to the phone and reducing the possibility of air bubbles forming between the protective film 10 and the phone. This also reduces the force applied to the protective film 10 along the thickness direction during application, making it more convenient for the user.
[0041] The protective film assembly 70 provided in this embodiment of the present invention, by providing a first positioning portion 22 on the first positioning film 20, and by having the minimum distance of the notch portion 221 along the second direction smaller than the dimension of the protective film along the second direction, enables the protective film 10 to be accurately applied to electronic devices such as mobile phones during application. By providing the notch portion 221 on the first positioning portion 22, the protective film 10 is more easily adhered to the mobile phone, reducing the possibility of air bubbles forming between the protective film 10 and the mobile phone. This, in turn, reduces the force applied to the protective film 10 along its thickness direction during application, making it more convenient for the user.
[0042] Specifically, the notch 221 is located on the side of the first positioning part 22 near the positioning film body part 21, which facilitates the first positioning part to withstand tension.
[0043] It is understood that the embodiments described below refer to Figures 2-5 In the examples, the notch 221 on one side of the first positioning member 611 along the second direction is used as an example. The notch 221 on the other side of the first positioning member 611 along the second direction is the same.
[0044] In some embodiments, see Figure 2 The first positioning part 22 has a notch edge 223 forming a notch part 221, the protective film 10 has two opposite sides along the second direction, the notch edge 223 is connected to the side, and the farthest distance between the notch edge 223 and the side along the second direction is 5mm to 18mm. Figure 2 L1 indicates the farthest distance in the second direction between the notch edge 223 and the side edge on the same side as the notch edge 223. That is, the difference between the size of the protective film 10 in the second direction and the minimum distance between the two notch edges 223 in the second direction is 10mm to 36mm. Thus, making the farthest distance in the second direction between the notch edge 223 and the side edge on the same side as the notch edge 223 greater than or equal to 5mm allows the minimum size of the first positioning portion 22 in the second direction to be close to that of the protective film 10, thereby helping to make the protective film 10 easier to adhere to the phone. Conversely, making the farthest distance in the second direction between the notch edge 223 and the side edge on the same side as the notch edge 223 less than or equal to 18mm helps to avoid the first positioning portion 22 being too small in the second direction, thereby reducing the risk of the first positioning film 20 tearing from the notch portion 221 and improving the durability of the protective film assembly 70.
[0045] Further, see Figure 1The positioning film also includes a second positioning part 23, which is connected to the end of the positioning film body 21 that is opposite to the first positioning part 22 along the first direction. The second positioning part 23 extends away from the edge of the protective film 10 and has two connecting parts 231 arranged along the second direction. The minimum distance between the two notched edges 223 along the second direction is the same as the distance between the two connecting parts 231 along the second direction. By providing a second positioning part 23 opposite to the first positioning part 22 along the first direction and arranging it with two connecting parts 231, the positioning of the protective film 10 can be further facilitated, making the positioning of the protective film 10 more accurate. Furthermore, the protective film 10 is more stable and less prone to movement during application, thus making the application more precise. The minimum distance between the two notched edges 223 along the second direction is the same as the distance between the two connecting parts 231 along the second direction. This helps to balance the forces exerted on the positioning film body 21 by the first positioning part 22 and the second positioning part 23 during film application, thereby reducing the deformation of the positioning film body 21 in the second direction. This further helps the protective film 10 adhere to the mobile phone and further reduces the possibility of air bubbles forming between the protective film 10 and the mobile phone, making it more convenient for users.
[0046] In some embodiments, see Figure 3 The notch edge 223 has a bent portion 2231, which is arc-shaped.
[0047] Thus, by making the bend 2331 arc-shaped, the stress on the bend 2231 is reduced, thereby reducing the probability of the bend 2231 tearing when subjected to tension, which is beneficial to improving the durability of the protective film assembly 70.
[0048] In some embodiments, see Figure 3 Along the second direction, the first positioning part 22 has two oppositely arranged first sides 222, and the first positioning part 22 also has a first arc-shaped side 225, which connects the first side 222 and the notched side 223. In this way, it helps to reduce the sharpness of the connection between the notched side 223 and the first side 222, thereby reducing the probability of the first positioning film 20 scratching the user.
[0049] In some embodiments, see Figure 3 The first positioning part 22 also includes a second arc-shaped edge 226, which connects the notch edge 223 to the side edge of the positioning part main body 21 in the second direction. This helps to reduce the sharpness of the connection between the notch edge 223 and the side edge of the positioning film main body 21, thereby reducing the probability of the first positioning film 20 scratching the user.
[0050] For some specific embodiments, see Figure 4 The distance between the notch edge 223 and the protective film 10 along the first direction is 3mm to 10mm. Figure 4 L2 indicates the distance between the side of the first positioning part 22 closest to the protective film 10 and the protective film 10 along the first direction. Thus, making the distance between the side of the first positioning part 22 closest to the protective film 10 and the protective film 10 along the first direction greater than or equal to 3mm helps to make the force transmitted from the first positioning part 22 to the positioning film body 21, and further to the protective film 10, more stable, thereby further facilitating the adhesion of the protective film 10 to electronic devices such as mobile phones; while making the distance between the side of the first positioning part 22 closest to the protective film 10 and the protective film 10 along the first direction less than or equal to 10mm helps to keep the first positioning part 22 stable, thereby keeping the protective film 10 stable during positioning and application.
[0051] It should be noted that, in Figure 4 The dashed line indicates the boundary between the first positioning film 20 and the positioning film body 21. In actual products, this boundary may not exist. Figure 4 The boundary line indicated by the dashed line.
[0052] For some specific embodiments, see Figure 5 The included angle between the two notched edges 223 is 30° to 60°. Figure 5 D1 indicates the included angle formed by the two sides of a bend 2231. Thus, making the included angle greater than or equal to 30° helps to prevent the first positioning film 20 from cracking at the notch 221 if the included angle is too small, thereby affecting the use of the protective film assembly 70; while making the included angle less than or equal to 60° helps to prevent the included angle of the notch 221 from being too large, thereby preventing the first positioning part 22 from being too large in the first direction, thus affecting its use.
[0053] In some specific embodiments, a notch edge 223 is bent to form multiple bends 2231. In this way, the notch 221 can be formed into different shapes, thereby helping to adapt to different working conditions.
[0054] In some specific embodiments, the notch edge 223 is an arc-shaped edge. In this way, the force applied by the first positioning part 22 to the positioning film body part 21 can be transmitted along the tangent of the arc-shaped edge, and the notch edge 221 formed in this way is not easy to tear and has good durability.
[0055] In some embodiments, see Figure 6 The protective film assembly 70 also includes a release film 30, which is disposed on the side of the protective film 10 opposite to the first positioning film 20 and is adhered to the protective film 10. The release film 30 can protect the protective film 10 before application, reducing the chance of the protective film 10 getting dusty, etc., thereby reducing the chance of dust stuck on the protective film 10 getting stuck between the protective film 10 and the phone when the protective film 10 is applied, thus improving user comfort.
[0056] Specifically, see Figure 6 The protective film assembly 70 also includes a pull-out strap 40. The first end 41 of the pull-out strap 40 along a first direction is located on the side of the release film 30 opposite to the protective film 10 and is connected to the release film 30. Since the release film 30 and the protective film 10 are adhered together, directly separating the release film 30 and the protective film 10 is difficult, and it is necessary to avoid contaminating the protective film 10 with dust during separation. Therefore, the pull-out strap 40 connected to the release film 30 is provided. Separating the release film 30 and the protective film 10 via the pull-out strap 40 makes separation easier and effectively reduces the chance of the protective film 10 becoming contaminated with dust during separation.
[0057] Further, see Figure 6 The release film 30 includes a second main body 31, a third positioning part 32, and a fourth positioning part 33. A first end 41 is connected to the fourth positioning part 33. The third positioning part 32 has a first connection port 321. The pull-out strap 40 has a second end 42 that is opposite to the first end 41 along a first direction. At least a portion of the second end 42 and the first positioning part 22 extend beyond the edge of the first connection port 321. The release film 30 is positioned by the third positioning part 32 and the fourth positioning part 33, thereby enabling more precise positioning of the protective film 10. The first end 41 of the pull-out strap 40 is connected to the release film 30, and the second end 42 is connected to the first positioning film 20, which helps to fix the pull-out strap 40, making it convenient for users and preventing it from swinging and falling off before use, thus affecting user experience.
[0058] The specific way in which the pull-out strip 40 is connected to the first positioning film 20 and the release film 30 is not limited. For example, double-sided adhesive strips are provided on the first positioning film 20 and the release film 30 respectively, and the pull-out strip 40 is connected to the first positioning film 20 and the release film 30 respectively through the double-sided adhesive strips.
[0059] In some specific embodiments, see Figure 7 The protective film assembly 70 also includes a waste removal layer 50, which is adhered between the first positioning film 20 and the release film 30. The waste removal layer 50 includes a waste removal positioning part 51 and a waste removal main frame 52, which are connected. The waste removal main frame 52 extends through the waste removal layer 50 along its thickness direction, and the protective film 10 is disposed within the waste removal main frame 52. By providing the waste removal layer 50, the positioning of the protective film 10 during application is further facilitated, thereby improving the accuracy of the application of the protective film 10.
[0060] Specifically, see Figure 7 The waste discharge positioning part 51 is provided with a second connection port 511 so that at least a portion of the second end 42 of the pull belt 40 passes through the second connection port 511 and connects with the first positioning part 22.
[0061] The specific forms of the first positioning part 22, the second positioning part 23, and the waste discharge positioning part 51 are not limited. For example, the first positioning part 22, the second positioning part 23, and the waste discharge positioning part 51 are respectively provided with positioning holes, and the external structure can be inserted into the positioning holes to fix the first positioning part 22, the second positioning part 23, and the waste discharge positioning part 51, thereby achieving positioning.
[0062] This embodiment of the utility model also provides a film application device 60, see [link]. Figure 8 and Figure 9 The assembly includes a housing 61, a pressing member 62, and a protective film assembly 70 as described in any of the above embodiments. The housing 61 has positioning members 611 at both ends along a first direction, and a first connecting portion 224 and a second connecting portion 231 are respectively connected to the positioning members 611. A notch 221 is disposed between the first connecting portion 224 and the second connecting portion 231 along the first direction. The pressing member 62 is connected to the housing 61 and is capable of reciprocating on the housing 61.
[0063] The screen protector 60 provided in this embodiment of the present invention places an electronic device such as a mobile phone in the receiving space formed by the housing 61, installs the protective film assembly 70 on the housing 61, and applies a force along the thickness direction of the protective film 10 to the protective film assembly 70 by the pressing member 62, so that the protective film 10 adheres to the electronic device such as the mobile phone. By using the protective film assembly 70 as described in any of the above embodiments, the screen protector 60 can apply the screen protector more conveniently, making it easier to adhere the protective film 10 to the mobile phone, reducing the possibility of air bubbles forming between the protective film 10 and the mobile phone, and also reducing the force applied to the protective film 10 along the thickness direction of the protective film 10 during application. This reduces the force that the pressing member 62 needs to apply to the protective film 10, allowing the pressing member 62 to complete the application of the protective film 10 without moving along the thickness direction of the protective film 10, thus making it more convenient for users.
[0064] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
