Technical Field
[0001] This utility model relates to the field of protective film technology, and in particular to a protective film composite structure with a buffer reinforcement layer. Background Technology
[0002] Key protectors are ultra-thin protective layers that adhere to the surface of keys, effectively extending their lifespan. The product features built-in cushioning to enhance the typing experience, and its precise cutting and positioning design allows for easy, bubble-free application. Furthermore, it supports personalized pattern customization, balancing practicality and aesthetics, making it an ideal accessory for esports players and office users.
[0003] Existing button protectors require peeling off the release film during the application process and manually aligning the protector with the button for application. However, this manual application process can easily lead to misalignment between the protector and the button, making it impossible to accurately adhere the protector to the button surface. This reduces the efficiency of the protector application process, and the protector is prone to collapse after prolonged use, resulting in poor button protection.
[0004] Therefore, those skilled in the art have provided a protective film assembly structure with a buffer reinforcement layer to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a protective film assembly structure with a buffer reinforcement layer. This facilitates positioning of the protective film body and the button during bonding, improves bonding efficiency, and enhances the performance of the protective film body.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A protective film assembly structure with a buffer reinforcement layer includes a protective film body, four positioning rings and a release film. The four positioning rings are paired up and each has a positioning angle fixedly provided on one side of each diagonal. The lower end of each of the four positioning angles and the upper part of the four positioning rings near the positioning angle are fixedly provided with removable adhesive. Release ears are fixedly provided in the middle of both sides of the release film. The protective film body includes a surface layer, a decorative layer fixedly disposed at the lower end of the surface layer, a buffer layer fixedly disposed at the lower end of the decorative layer, a plurality of annular grooves of different sizes opened above the buffer layer, a reinforcing ring fixedly disposed inside each of the plurality of annular grooves, a base layer fixedly disposed at the lower end of the buffer layer, and an adhesive layer fixedly disposed at the lower end of the base layer.
[0007] Furthermore, the four positioning angles and the four positioning rings are all attached to the protective film body with removable adhesive, and the four positioning angles are paired up and have beveled edges on opposite sides.
[0008] Furthermore, the release film pressure-sensitive adhesive is bonded to the lower end of the protective film body.
[0009] Furthermore, the upper end of the protective film body is provided with wear-resistant protrusions.
[0010] Furthermore, the surface layer is made of a nano-hardened coating, and the decorative layer is made of a screen-printed marking layer.
[0011] Furthermore, the buffer layer is made of foamed polyurethane, and the reinforcing ring is made of PET.
[0012] Furthermore, the bonding layer is made of a low-tack silicone coating, and the base layer is made of a TPU film.
[0013] This utility model has the following beneficial effects: 1. The present invention proposes a protective film assembly structure with a buffer reinforcement layer. By setting a positioning ring, positioning angle and removable adhesive, the protective film body is conveniently positioned when it is attached to the button, which can ensure that the protective film body is tightly attached to the button surface, wrinkle-resistant and does not curl up, thus improving the efficiency of the protective film body and the button attachment.
[0014] 2. The present invention proposes a protective film assembly structure with a buffer reinforcement layer. The surface layer of the protective film body structure improves scratch resistance and wear resistance, and extends service life. The decorative layer provides button markings. The reinforcement ring inside the ring groove of the buffer layer absorbs and disperses the pressing pressure and reduces local stress, thereby improving the overall structural strength of the protective film body. The base layer supports the other layers, ensuring that the protective film will not be excessively stretched or deformed. The adhesive layer ensures that it is firmly attached to the button and there is no residue peeling off. Attached Figure Description

[0017] 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.
[0018] Reference Figures 1-6 An embodiment of this utility model is provided: a protective film assembly structure with a buffer reinforcement layer, including a protective film body 1, four positioning rings 5 and a release film 2. The four positioning rings 5 are paired up and each is fixedly provided with a positioning angle 4 on one side of the diagonal. The lower end of the four positioning angles 4 and the upper side of the four positioning rings 5 near the positioning angle 4 are fixedly provided with a removable adhesive 8. The release film 2 is fixedly provided with release ears 3 in the middle of both sides. The four positioning corners 4 and the four positioning rings 5 are all attached to the protective film body 1 by removable adhesive 8. The four positioning corners 4 are paired up and diagonally opposite each other with beveled edges 6. The release film 2 is bonded to the lower end of the protective film body 1 with pressure-sensitive adhesive. The upper end of the protective film body 1 is provided with wear-resistant protrusions 7.
[0019] Specifically, positioning angles 4 are set on opposite sides of each pair of positioning rings 5 to fix the positioning rings 5 and the positioning angles 4. The positioning rings 5 are then attached to the four corners of the protective film body 1 with removable adhesive 8, so that the lower end of the positioning rings 5 is located below the protective film body 1. This facilitates positioning when the protective film body 1 is attached to the button, improving the efficiency of the attachment process. The release ears 3 on both sides of the release film 2 are used to position the release film 2 at the lower end of the protective film body 1. After pressure-sensitive adhesive is applied, the release film 2 is attached to the protective film body 1, which facilitates protection of the attachment surface of the protective film body 1. The beveled edge 6 on the positioning angle 4 makes it easy to peel off the positioning angle 4 and positioning rings 5 from the protective film body 1 after attachment. The wear-resistant protrusion 7 on the upper end of the protective film body 1 increases friction when the protective film body 1 is touched, making the button touch more stable.
[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6The protective film body 1 includes a surface layer 101, a decorative layer 102 fixedly disposed at the lower end of the surface layer 101, a buffer layer 103 fixedly disposed at the lower end of the decorative layer 102, a plurality of annular grooves 106 of different sizes are opened above the buffer layer 103, a reinforcing ring 107 is fixedly disposed inside the plurality of annular grooves 106, a base layer 104 is fixedly disposed at the lower end of the buffer layer 103, and an adhesive layer 105 is fixedly disposed at the lower end of the base layer 104. The surface layer 101 is made of nano-cured coating, the decorative layer 102 is made of screen-printed marking layer, the buffer layer 103 is made of foamed polyurethane, the reinforcing ring 107 is made of PET, the bonding layer 105 is made of low-tack silicone coating, and the base layer 104 is made of TPU film.
[0021] Specifically, the surface layer 101 is a nano-hardening coating, which can improve the scratch resistance and wear resistance of the protective film body 1 and extend the film life. The decorative layer 102 is a screen-printed marking layer to facilitate the differentiation of button markings. The buffer layer 103 is made of foamed polyurethane, which can effectively absorb and buffer the pressure on the buttons and provide high rebound after being pressed. It is fixed inside the annular groove 106 opened in the buffer layer 103 by a reinforcing ring 107. The reinforcing ring 107 is made of PET material, which is not easy to stretch and deform, and can provide precise positioning and stable support. The buffer layer 103 and the reinforcing ring 107 work together to prevent the protective film body 1 from collapsing as a whole. The base layer 104 is a TPU film that supports the other layers, ensuring that the protective film body 1 will not be overstretched and deformed, and ensuring that the protective film body 1 can maintain the pre-cut shape. The bonding layer 105 is a low-tack silicone coating, which facilitates the bonding and adhesion of the buttons, and leaves no residue on the buttons when they are peeled off, thus improving the overall performance and lifespan of the protective film body 1.
[0022] Working principle: When applying the protective film body 1 to the button, the release film 2 below the protective film body 1 is peeled off through the release ear 3 beforehand. The protective film body 1 is then placed directly above the button, so that the positioning rings 5 at the four corners of the protective film body 1 are pressed against the four corners of the button. The protective film body 1 is then pressed onto the button to apply it. After the application is complete, the positioning angle 4 and the positioning ring 5 are peeled off through the bevel 6 on the positioning angle 4, thus completing the application of the protective film body 1 to the button and improving the application efficiency.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
