[0002] As we all know, screen protectors for common electronic products such as mobile phones, tablets, and educational devices are a way to protect the screens. However, the screen protectors currently available to consumers are usually sold separately. To properly apply a screen protector, it is often necessary to use an additional tool or purchase a screen protector application kit, which greatly increases the difficulty and cost for customers. Existing screen protector application aids are mainly conventional screen protector application kits and dust-free application boxes. Although screen protector application kits can reduce the difficulty of application, they require external force to press and fix the positioning film. During the application process, improper external force can cause the positioning film to shift and fall off, resulting in misalignment between the screen protector and the phone screen. Utility Model Content

[0003] The present invention provides a screen protector auxiliary shell and a screen protector kit to solve the technical problem that the positioning film may shift and fall off due to unsuitable external force during the screen protector application process, resulting in misalignment between the protective film and the mobile phone screen.

[0006] The positioning frame has an installation cavity for accommodating positioning electronic products. The installation cavity has a first end and a second end that are disposed opposite to each other along its depth direction. The first end is the opening end of the installation cavity.

[0007] A support plate is integrally connected to the edge of the positioning frame and located at the second end. The support plate extends radially inward along the mounting cavity to form the bottom wall of the mounting cavity.

[0008] At least two flexible and bendable barbs are integrally connected to opposite sides of the positioning frame. Each barb has an integrally connected connecting end, a suspended end, and a positioning block. The connecting end is connected to the side of the positioning frame located at the first end, and the suspended end is located on the side of the positioning frame located at the second end. The positioning block is disposed between the connecting end and the suspended end, and protrudes inward toward the mounting cavity along a direction perpendicular to the depth of the mounting cavity. The positioning block and the suspended end form a first boss, and the positioning block and the connecting end form a second boss. The first boss is used to support the tempered glass film and position the tempered glass film between the first boss and the support plate. The second boss is used to support the electronic product, and the screen of the electronic product is attached to the tempered glass film when the barb deforms outward.

[0009] In one embodiment, the side wall of the positioning frame is provided with a clearance notch communicating with the mounting cavity, the barb is located in the clearance notch, and when the positioning block is radially squeezed by the electronic product, the suspended end tilts away from the mounting cavity through the clearance notch.

[0010] In one embodiment, the barb and the positioning frame are integrally injection molded structures. The sidewall of the positioning frame is provided with a first groove and a second groove that extend longitudinally and are connected laterally. The barb is formed between the first groove and the second groove in the positioning frame.

[0011] In one embodiment, the connecting end includes a first guide surface formed on the side of the connecting end facing the mounting cavity, the first guide surface being exposed outside the opening of the mounting cavity, the first guide surface being inclined in the depth direction of the mounting cavity, and the radial dimension of the first guide surface gradually decreasing in the direction from the first end to the second end.

[0012] In one embodiment, the positioning block includes a second guide surface on one side of the first boss, the second guide surface being inclined in the depth direction of the mounting cavity, and the radial dimension of the second guide surface gradually increasing in the direction from the first end to the second end.

[0013] In one embodiment, the two barbs are positioned opposite each other along the width direction of the positioning frame.

[0014] In one embodiment, the thickness of the connecting end along the radial direction of the mounting cavity is smaller than the thickness of the suspended end along the radial direction of the mounting cavity.

[0015] In one embodiment, the support plate surrounds the side of the mounting cavity to form a closed frame structure, and the support plate and the positioning frame are integrally injection molded to enclose and form the mounting cavity.

[0016] In one embodiment, the film-applying auxiliary shell further includes a locking block, which protrudes from the inner wall of the mounting cavity and is located at the second end. The locking block and the barb are spaced apart around the side periphery of the mounting cavity. In the radial direction of the mounting cavity, the height of the locking block protruding from the inner wall of the mounting cavity is not greater than the maximum height of the positioning block protruding from the inner wall of the mounting cavity.

[0035] Reference Figure 3 and Figure 4 The film-applying auxiliary housing 10 includes a positioning frame 100, a support plate 200, and barbs 300, with the support plate 200 and barbs 300 both connected to the positioning frame 100. Specifically, it is combined with... Figure 1 The positioning frame 100 has a mounting cavity 110 for accommodating the positioning electronic product and the tempered glass screen protector 20. The mounting cavity 110 has a first end 111 and a second end 112 opposite to each other along its depth direction. The first end 111 is the opening side of the mounting cavity 110. The electronic product is mounted in the mounting cavity 110 from the first end 111 toward the second end 112, and the tempered glass screen protector 20 is positioned and mounted at the second end 112 of the mounting cavity 110. A support plate 200 is integrally connected to the edge of the positioning frame 100 and located at the second end 112. The support plate 200 extends radially inward along the mounting cavity 110 to form the bottom wall of the mounting cavity 110. The support plate 200 provides support and bearing function for the tempered glass screen protector 20 and the electronic product to prevent the tempered glass screen protector 20 and the electronic product from detaching from the mounting cavity 110 at the second end 112. The number of barbs 300 is at least two and they are elastic. Here, this embodiment uses two barbs 300 as an example. The two barbs 300 are integrally connected to the edges of opposite sides of the positioning frame 100. Specifically, Figure 4 The diagram illustrates that the barb 300 has an integrally connected connecting end 310, a suspended end 320, and a positioning block 330. The connecting end 310 is connected to the side of the positioning frame 100 located at the first end 111, and the suspended end 320 is located on the side of the positioning frame 100 located at the second end 112.

[0036] Furthermore, in conjunction with references Figure 4-6The positioning block 330 is disposed between the connecting end 310 and the suspended end 320. The positioning block 330 protrudes radially inward along the mounting cavity 110. The positioning block 330 and the suspended end 320 form a first boss 340, and the positioning block 330 and the connecting end 310 form a second boss 350. Figure 6 As illustrated, the first boss 340 is used to support the tempered glass film 20 and to position the tempered glass film 20 between the first boss 340 and the support plate 200; the second boss 350 is used to support the electronic product and the screen of the electronic product can be attached to the tempered glass film 20 when the hook 300 deforms outward.

[0037] This utility model provides a screen protector auxiliary shell 10 and a screen protector kit 1. The screen protector kit 1 includes a tempered glass screen protector 20 and the screen protector auxiliary shell 10. The screen protector auxiliary shell 10 has two elastic barbs 300 located on opposite sides of a positioning frame 100. Each barb 300 has a positioning block 330, with a first protrusion 340 on one side and a second protrusion 350 on the other. The first protrusion 340 supports the tempered glass screen protector 20 and positions it between the first protrusion 340 and the support plate 200. The second protrusion 350 supports the electronic product, and the screen of the electronic product adheres to the tempered glass screen protector 20 when the barbs 300 deform outwards. This ensures that the tempered glass screen protector 20 remains aligned with the screen of the electronic product during the application process, improving alignment accuracy and achieving a better application effect. The screen protector auxiliary shell 10 of this application has a simple structure, is easy for users to operate, and enables convenient and accurate alignment and application of screen protectors to electronic products.

[0038] Preferably, refer to Figure 4 In one embodiment, the side wall of the positioning frame 100 has a clearance notch 120 communicating with the mounting cavity 110. The barb 300 is located within the clearance notch 120. When the positioning block 330 is radially pressed outward by the electronic product, the suspended end 320 tilts away from the mounting cavity 110 through the clearance notch 120. The barb 300 accumulates elastic force radially, which can drive the barb 300 to tilt radially inward toward the mounting cavity 110 to reset. Here, the clearance notch 120 provides deformation space for the barb 300 to accumulate or release elastic force. In this embodiment, the clearance notch 120 can be... Figure 4The channel connecting the outside world and the mounting cavity 110 shown is surrounded by the positioning frame 100 and the support plate 200. In other embodiments, the clearance notch 120 can also be in the form of a recessed groove, as long as it can provide deformation space for the barb 300. The connecting end 310 is connected to the inner sidewall of the clearance notch 120 located at the first end 111. The clearance notch 120 provides installation space for the barb 300, increasing the structural compactness of the entire film-applying auxiliary shell 10. It should be noted that in other embodiments, the clearance notch 120 is not required. The length extension direction of the barb 300 is inclined to the depth direction of the mounting cavity 110, and the barb 300 is located inside the mounting cavity 110, which can also cause the barb 300 to be radially squeezed by the electronic product and tilted away from the mounting cavity 110. Therefore, in this application, without considering the structural compactness of the film-applying auxiliary shell 10, the setting of the clearance notch 120 is not limited, and the implementation form of the clearance notch 120 is not limited.

[0039] Preferably, continue to refer to Figure 4 In one embodiment, the barb 300 and the positioning frame 100 are integrally injection molded to enhance the connection stability between the barb 300 and the positioning frame 100; the sidewall of the positioning frame 100 is provided with a longitudinally extending and laterally connected first groove 121 and second groove 122, and the positioning frame 100 forms the barb 300 between the first groove 121 and the second groove 122. Figure 4 As shown, the connecting end 310 is connected to the inner wall of the clearance notch 120 located at the first end 111, and the clearance notch 120 is divided into a first groove 121 and a second groove 122. The portion of the barb 300, except for the connecting end 310, is spaced from the inner wall of the clearance notch 120, allowing the barb 300 to move flexibly within the clearance notch 120 to accumulate or release elastic force, reducing contact wear between the barb 300 and the inner wall of the clearance notch 120 during movement. It should be noted that, firstly, without considering the connection stability of the barb 300, the connection method between the barb 300 and the positioning frame 100 is not limited; it can be injection molded as a single unit, or bonded or interference-fitted. Secondly, without considering the contact wear of the barb 300, the presence or absence of the first groove 121 or the second groove 122 is not limited in this application.

[0040] Preferably, in conjunction with reference Figure 4 and Figure 6In one embodiment, the connecting end 310 includes a first guiding surface 311, which is formed on the side of the connecting end 310 facing the mounting cavity 110. The first guiding surface 311 is exposed outside the opening of the mounting cavity 110 and is used to guide the installation of electronic products into the mounting cavity 110. The first guiding surface 311 is inclined to the depth direction of the mounting cavity 110. The first guiding surface 311 can be an arc surface or a slope. In the direction from the first end 111 to the second end 112, the radial dimension of the first guiding surface 311 gradually decreases. During the installation of the electronic product into the mounting cavity 110, the edge of the electronic product always abuts against the first guiding surface 311. The barb 300 is squeezed and warped outward along the radial direction of the mounting cavity 110, resulting in elastic deformation to accumulate elastic force. This elastic force can further fix the electronic product in place within the mounting cavity 110. Moreover, the first guiding surface 311 plays a guiding role in installation, making it more convenient for users to install electronic products into the mounting cavity 110. Users can blindly insert electronic products. It should be noted that in other embodiments, the first guide surface 311 is not required, and the electronic product can be manually aligned and installed in the mounting cavity 110. Therefore, the presence or absence of the first guide surface 311 is not limited.

[0041] Preferably, in conjunction with reference Figure 4 and Figure 6 In one embodiment, the positioning block 330 includes a second guide surface 331 on one side of the first boss 340. The second guide surface 331 is used to guide the electronic product to move closer to the tempered glass film 20. The second guide surface 331 is inclined to the depth direction of the mounting cavity 110. The second guide surface 331 can be an arc surface or an inclined surface. In the direction from the first end 111 to the second end 112, the radial dimension of the second guide surface 331 gradually increases. During the process of the electronic product moving closer to the tempered glass film 20 along the depth direction of the mounting cavity 110, the edge of the electronic product always abuts against the second guide surface 331, and the barb 300 is elastically deformed by bending outward along the radial direction of the mounting cavity 110. It should be noted that the edge of the electronic product can be a right-angled edge, an oblique edge, or an arc-shaped chamfered edge. Therefore, it should be understood that in this application, the presence or absence of the second guide surface 331 is not limited.

[0042] Preferably, refer to Figure 3 In one embodiment, the two barbs 300 are arranged opposite each other along the width direction of the positioning frame 100, that is, symmetrically arranged relative to the electronic product, to enhance the installation stability of the positioning frame 100 for the tempered glass screen protector 20 and the electronic product. It should be noted that, without considering the stability of installation and fixation, in other embodiments, the two barbs 300 only need to be arranged on the opposite sides of the edge of the positioning frame, and can be symmetrical left and right, staggered left and right, or symmetrical or staggered top and bottom.

[0043] Preferably, in conjunction with reference Figure 4 and Figure 6 In one embodiment, the radial thickness of the connecting end 310 along the mounting cavity 110 is smaller than the radial thickness of the suspended end 320 along the mounting cavity 110. This relative thickness setting makes the extrusion and prying of the entire barb 300 more effortless and flexible. It should be noted that, without considering effort saving, the relative thickness of the connecting end 310 and the suspended end 320 is not limited.

[0044] Preferably, refer to Figure 3 In one embodiment, the support plate 200 surrounds the side of the mounting cavity 110 to form a closed frame structure, improving the support and load-bearing balance of the support plate 200 and enhancing the installation stability of the mounting cavity 110 itself. The support plate 200 and the positioning frame 100 are injection molded integrally to enhance the connection stability between the two. The support plate 200 and the positioning frame 100 together enclose the mounting cavity 110, with the positioning frame 100 serving as the side portion of the mounting cavity 110 and the support plate 200 serving as the bottom wall of the mounting cavity 110. It should be noted that, firstly, without considering the installation stability of the mounting cavity 110 itself, whether the support plate 200 is a closed frame structure is not limited; secondly, without considering the connection stability between the support plate 200 and the positioning frame 100, the connection method between the two is not limited, and in other embodiments, it can be bonding or interference fit, etc.

[0045] Preferably, in conjunction with reference Figure 3 and Figure 6 In one embodiment, the film-applying auxiliary housing 10 includes a plurality of locking blocks 400, which protrude from the inner wall of the mounting cavity 110 and are located at the second end 112. Figure 3 The illustration shows that multiple locking blocks 400 and barbs 300 are spaced apart around the periphery of the mounting cavity 110. Along the radial direction of the mounting cavity 110, the locking blocks 400 and the second protrusion 350 together serve to support and position the electronic product; the locking blocks 400 also function as a positioning element for the electronic product. The height of the locking blocks 400 protruding from the inner wall of the mounting cavity 110 is no greater than the maximum height of the positioning block 330 protruding from the inner wall of the mounting cavity 110, so that the electronic product can move along the depth direction of the mounting cavity 110 towards the tempered glass film 20. It should be noted that the protrusion height of the positioning block 330 changes with the deformation of the barbs 300. It should be pointed out that in this application, the positioning of the electronic product within the mounting cavity 110 is not considered, and the presence or absence of locking blocks 400 is not limited.

[0046] Reference Figure 1 , Figure 2 and Figure 6 In the film application kit 1, the tempered glass film 20 is first positioned between the first boss 340 and the bottom wall (bearing plate 200) of the mounting cavity 110. Figure 6(As shown), then the screen protector set 1 is aligned and fitted onto one side of the screen of the electronic product. The second protrusion 350 supports the electronic product and contacts the screen of the electronic product. The user presses down the screen protector set 1. The side edge of the electronic product always abuts against the second guide surface 331. The positioning block 330 is raised away from the mounting cavity 110. The electronic product approaches and fits the tempered glass film 20 along the depth direction of the mounting cavity 110. The tempered glass screen protector 20 includes a protective film 21, a dust removal film 22, and a pull-out film 23. The protective film 21 is opposite to the carrier plate 200. The dust removal film 22 is attached to the side of the protective film 21 away from the carrier plate 200. The pull-out film 23 is connected to one end of the dust removal film 22 and is placed between the dust removal film 22 and the electronic product. The pull-out film 23 extends out of the film application auxiliary shell 10 and can be driven by external force to flip the dust removal film 22 outward and separate it from the protective film 21. The external force is generally pulled by the user. At the same time, the dust removal film 22 moves away from the mounting cavity 110, and the protective film 21 can automatically adhere to the screen of the electronic product. The film application auxiliary shell 10 is removed, and the protective film 21 is cleaned to complete the screen protection of the electronic product.
