Description

Technical Field

[0001] This utility model relates to the field of electronic accessories technology, and in particular to a screen protector application device. Background Technology

[0002] Electronic device screens are easily scratched, so consumers usually apply a protective film to the screen of electronic devices (such as mobile phones and tablets) to protect them. Among these, tempered glass screen protectors are the most common type of protective film because they have advantages such as good light transmission, comfortable feel, and sensitive touch.

[0003] Currently, screen protector application devices exist for assisted screen protector application. The traditional application process involves: first, using the device to hold the screen of the device to be protected; then, peeling off the release liner of the protective film; next, placing the protective film into the device, aligning the adhesive side with the screen; and finally, pressing the film to securely adhere it. However, because the release liner is removed beforehand, the adhesive side of the protective film easily attracts dust and other impurities. This causes air bubbles to form in dusty areas when the film is pressed onto the screen, affecting the final application result. Utility Model Content

[0004] The main purpose of this utility model is to provide a screen protector application device, which aims to solve the technical problem that when applying a screen protector using a screen protector application device, air bubbles are easily generated on the display screen of the device to be covered, resulting in uneven application of the protective film and affecting the application effect of the protective film.

[0005] To achieve the above objectives, this utility model proposes a screen protector application device, comprising:

[0010] In some embodiments, the first claw includes a first bent portion, a second bent portion, and a third bent portion. The second bent portion is connected to one end of the first bent portion, and the third bent portion is connected to the end of the second bent portion away from the first bent portion. The third bent portion forms a support platform, and a hollow portion is formed between the first bent portion, the second bent portion, and the third bent portion, so that the first claw is a flexible claw.

[0011] Alternatively, the second claw includes a first bent portion, a second bent portion, and a third bent portion. The second bent portion is connected to one end of the first bent portion, and the third bent portion is connected to the end of the second bent portion away from the first bent portion. The third bent portion forms a support platform, and a hollow portion is formed between the first bent portion, the second bent portion, and the third bent portion, so that the second claw is a flexible claw.

[0012] In some embodiments, the bottom wall is provided with a protrusion, and the side of the protrusion away from the bottom wall contacts the display screen of the device to be coated.

[0013] In some embodiments, the screen protector device includes a positioning film connected to the side of the protector member away from the release film, and the positioning film includes a first positioning hole and a second positioning hole disposed opposite to each other.

[0014] The bottom wall includes a first positioning end and a second positioning end disposed opposite to each other. The first positioning end is provided with a first positioning part and a first hook groove. The second positioning end is provided with a second positioning part and a second hook groove.

[0015] The first positioning hole is connected to the first hook groove, and the second positioning hole is connected to the second hook groove, which is used to realize the positioning connection of the positioning film to the bottom wall.

[0016] In some embodiments, the positioning film includes a plurality of first positioning holes and a plurality of second positioning holes, the first positioning end includes a plurality of first positioning portions, and the second positioning end includes a plurality of second positioning portions;

[0017] The first positioning hole and the first positioning part are respectively arranged, and the second positioning hole and the second positioning part are respectively arranged. The distance between two adjacent first positioning parts and the distance between two adjacent second positioning parts are not equal.

[0018] In some embodiments, at least one of the first positioning end and the second positioning end is provided with a third positioning part, which is used to position the tear-off portion of the release film.

[0019] In some embodiments, the bottom wall is provided with an elastic element, which contacts the side of the film-applying component away from the release film, for attaching the film-applying component to the display screen of the device to be film-applied.

[0021] In some embodiments, along the direction from the first sidewall to the second sidewall, the first sidewall has a first claw disposed corresponding to the elastic member;

[0022] Alternatively, along the direction from the first sidewall to the second sidewall, the second sidewall has a second claw corresponding to the elastic element.

[0023] In some embodiments, the bottom wall is provided with an observation hole.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] In the technical solution of this utility model, when using the screen protector application device provided by this utility model to apply a screen protector to the display screen of the device to be protected, the screen protector is first placed in the receiving space, without removing the release film beforehand. Then, the first claw is engaged with one end of the display screen, and the second claw is engaged with the opposite end. The first and second claws are used to secure the screen protector application device and the display screen. During this process, the screen protector is aligned with the display screen, with the adhesive surface of the screen protector facing the display screen. Finally, peel off the release film from the screen protector and press the adhesive side of the screen protector onto the display screen of the device to be covered. During this process, as the release film is gradually peeled off, the adhesive side of the screen protector is gradually exposed. Because the screen protector is pre-installed and positioned on the display screen using this screen protector device, and the adhesive side of the screen protector is facing the display screen, the gap between the adhesive side of the screen protector and the display screen is very small. This makes it difficult for dust and other impurities to stick to the adhesive side of the screen protector. At the same time, during the process of peeling off the release film, the static electricity on the release film can attract and carry away the dust on the surface of the display screen, thereby further ensuring the cleanliness between the adhesive side of the screen protector and the display screen. This effectively avoids the formation of air bubbles between the screen protector and the display screen due to the presence of dust and other impurities, improving the aesthetics of the screen protector application.

[0026] When applying a screen protector using the device provided by this invention, the screen protector is first positioned on the display screen of the device to be protected. This ensures stability during application and prevents misalignment due to hand tremors, thus avoiding waste of the screen protector. The release liner is removed only after the screen protector is properly positioned on the display screen. This effectively prevents dust and other impurities from adhering to the screen protector due to premature removal of the release liner, thus preventing air bubbles from forming between the screen protector and the display screen, ensuring a smooth application and improving the aesthetics of the screen protector.

[0055] 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.

[0058] Electronic device screens are easily scratched, so consumers usually apply a protective film to the screen of electronic devices (such as mobile phones and tablets) to protect them. Among these, tempered glass screen protectors are the most common type of protective film because they have advantages such as good light transmission, comfortable feel, and sensitive touch.

[0059] Currently, screen protector application devices exist for assisted screen protector application. The traditional application process involves: first, using the device to hold the screen of the device to be protected; then, peeling off the release liner of the protective film; next, placing the protective film into the device, aligning the adhesive side with the screen; and finally, pressing the film to securely adhere it. However, because the release liner is removed beforehand, the adhesive side of the protective film easily attracts dust and other impurities. This causes air bubbles to form in dusty areas when the film is pressed onto the screen, affecting the final application result.

[0060] Taking screen protector application on a car's center console as an example, the process involves first securing the screen protector applicator to the console, then peeling off the release liner. Next, the protector is placed into the applicator, ensuring the adhesive side faces the screen. Finally, the protector is pressed to securely adhere to the screen, and the applicator is removed. During this process, because the release liner is removed beforehand, the adhesive side of the protector easily attracts dust and other impurities. This results in air bubbles on the screen when the protector is pressed onto the center console, affecting its appearance.

[0061] Therefore, in order to solve the technical problem that air bubbles easily form on the display screen of the device to be covered when using a screen protector application device, resulting in uneven application of the protective film and affecting the application effect, refer to Figures 1 to 6 An embodiment of this utility model provides a screen protector application device, which includes a bottom wall 100, a first side wall 200, and a second side wall 300. The first side wall 200 is connected to a first side of the bottom wall 100, that is, the first side wall 200 is disposed at one end of the bottom wall 100. The first side wall 200 is provided with a first claw 210. The second side wall 300 is connected to a second side of the bottom wall 100, and the second side wall and the first side wall are disposed opposite to each other, that is, the second side wall 300 is disposed at the end of the bottom wall 100 away from the first side wall 200. The second side wall 300 is provided with a second claw 310. The bottom wall 100, the first side wall 200, and the second side wall 300 enclose a receiving space 400, which is used to receive a screen protector 500 (which can be a tempered glass screen protector). The first claw 210 and the second claw 310 are arranged toward the receiving space 400. The first claw 210 is engaged with one end of the display screen of the device to be covered, and the second claw 310 is engaged with the opposite end of the display screen of the device to be covered, so as to realize the engagement between the screen protector and the display screen of the device to be covered.

[0062] Specifically, in this embodiment, when applying the screen protector 500 to the display screen of the device to be protected using the screen protector device provided in this embodiment, the screen protector 500 is first placed in the receiving space 400. During this process, the release film 510 of the screen protector 500 is not removed beforehand. Then, the first claw 210 is engaged with one end of the display screen of the device to be protected, and the second claw 310 is engaged with the opposite end of the display screen of the device to be protected. The first claw 210 and the second claw 310 are used to achieve the engagement and fixation between the screen protector device and the display screen of the device to be protected. During this process, the screen protector 500 is aligned with the display screen of the device to be protected, and the adhesive surface of the screen protector 500 faces the display screen of the device to be protected. Finally, the release film 510 on the film applicator 500 is peeled off, and the adhesive side of the film applicator 500 is pressed onto the display screen of the device to be covered. During this process, as the release film 510 is gradually peeled off, the adhesive side of the film applicator 500 is gradually exposed. Since the film applicator 500 is pre-installed and positioned on the display screen of the device to be covered using this screen protector, and the adhesive side of the film applicator 500 faces the display screen, the gap between the adhesive side of the film applicator 500 and the display screen is very small, making it difficult for dust and other impurities to stick to the adhesive side of the film applicator 500. At the same time, during the process of peeling off the release film 510, the static electricity on the release film 510 can attract and carry away the dust on the surface of the display screen, thereby further ensuring the cleanliness between the adhesive side of the film applicator 500 and the display screen, effectively avoiding the formation of air bubbles between the film applicator 500 and the display screen due to the presence of dust and other impurities, and improving the aesthetics of the screen protector.

[0063] Preferably, in this embodiment, during the process of pressing the adhesive surface of the film-applying component 500 onto the display screen of the device to be covered, the middle position of the film-applying component 500 can be pressed, so that the adhesive surface of the film-applying component 500 gradually adheres from the middle to both sides. This method helps to gradually expel air bubbles generated during the film application process, so that the film-applying component 500 and the display screen of the device to be covered achieve an air bubble-free adhesion effect.

[0064] When applying a screen protector using the device provided in this embodiment, the screen protector 500 is first positioned on the display screen of the device to be protected. This ensures stability during the application process and prevents misalignment of the screen protector 500 due to hand tremors, thus avoiding waste. Only after the screen protector 500 is properly positioned on the display screen is the release film 510 removed. This effectively prevents dust and other impurities from adhering to the screen protector 500 due to premature removal of the release film 510, thus preventing air bubbles from forming between the screen protector 500 and the display screen. This ensures the flatness of the screen protector application and improves its aesthetics.

[0065] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 The first claw 210 includes a first bent portion 311, a second bent portion 312, and a third bent portion 313. The second bent portion 312 is connected to one end of the first bent portion 311, and the third bent portion 313 is connected to the end of the second bent portion 312 away from the first bent portion 311. The third bent portion 313 forms a support platform 314, and a hollow portion 315 is formed between the first bent portion 311, the second bent portion 312, and the third bent portion 313, so that the first claw 210 is a flexible claw.

[0066] Alternatively, the second claw 310 includes a first bent portion 311, a second bent portion 312, and a third bent portion 313. The second bent portion 312 is connected to one end of the first bent portion 311, and the third bent portion 313 is connected to the end of the second bent portion 312 away from the first bent portion 311. The third bent portion 313 forms a support platform 314, and a hollow portion 315 is formed between the first bent portion 311, the second bent portion 312, and the third bent portion 313, so that the second claw 310 is a flexible claw.

[0067] Specifically, in this embodiment, at least one of the first claw 210 and the second claw 310 is a flexible claw. Taking the second claw 310 as an example, when the screen protector applicator is installed and positioned on the display screen of the device to be protected, the first claw 210 is first hooked onto the upper end of the display screen, so that the screen protector applicator can initially rest on the display screen. Then, the second claw 310 is engaged with the lower end of the display screen. Due to the first bend 311 and the second bend of the second claw 310... A hollow portion 315 is formed between portion 312 and the third bending portion 313. After the second claw 310 is subjected to compressive force, the third bending portion 313 tends to move towards the first bending portion 311. Therefore, when the second claw 310 is engaged with the lower end of the display screen of the device to be coated, the second claw 310 undergoes a slight elastic deformation due to the force, thereby clamping the display screen between the first claw 210 and the second claw 310, ensuring the connection stability of the screen coating device on the display screen. When the screen coating device is removed from the display screen, the second claw 310 tends to recover its elastic deformation, thereby allowing the second claw 310 to return to its initial state.

[0068] Furthermore, within the elastic deformation range of the second claw 310, the screen protector applicator can use the first claw 210 and the second claw 310 to clamp onto the display screen of different models of devices to be covered with screen protectors, thereby improving the applicability of the screen protector applicator.

[0069] It is understood that in some embodiments, the first claw 210 can also be attached to the lower end of the display screen of the device to be coated. In this case, the second claw 310 can be attached to the upper end of the display screen of the device to be coated. The clamping effect is the same as that of the above embodiment, which "attaches the first claw 210 to the upper end of the display screen of the device to be coated and the second claw 310 to the lower end of the display screen of the device to be coated". However, compared with the clamping method provided in this embodiment (the clamping method here refers to attaching the first claw 210 to the lower end of the display screen of the device to be coated and the second claw 310 to the upper end of the display screen of the device to be coated), the clamping method in the above embodiment (the clamping method here refers to attaching the first claw 210 to the upper end of the display screen of the device to be coated and the second claw 310 to the lower end of the display screen of the device to be coated) is more convenient for users to operate.

[0070] Similarly, the first jaw 210 can also be a flexible jaw, or both the first jaw 210 and the second jaw 310 can be flexible jaws. The operation steps are the same as those described in the above embodiments, and will not be repeated here.

[0071] In some embodiments, refer to Figure 1 , Figure 4 and Figure 6 The bottom wall 100 is provided with a protrusion 410. The side of the protrusion 410 away from the bottom wall 100 contacts the display screen of the device to be filmed, so that a tear gap is formed between the display screen of the device to be filmed and the release film 510 of the film-applying component 500.

[0072] Specifically, in this embodiment, by placing the display screen of the device to be covered against the protrusion 410, it is beneficial to increase the reserved space between the display screen of the device to be covered and the film applicator 500, thereby facilitating the removal of the release film 510 from the film applicator 500. It is understood that if the display screen of the device to be covered and the film applicator 500 are tightly attached, it will increase the resistance when removing the release film 510, and may even lead to the risk of the release film 510 being torn, affecting the normal operation of screen protection application.

[0073] In some embodiments, refer to Figure 2 , Figure 5 and Figure 6 The screen protector applicator includes a positioning film 600, which is connected to the side of the screen protector 500 away from the release film 510. The positioning film 600 includes a first positioning hole 610 and a second positioning hole 620 disposed opposite to each other. The bottom wall 100 includes a first positioning end 110 and a second positioning end 120 disposed opposite to each other. The first positioning end 110 is provided with a first positioning part 111 and a first hook groove 1111. The second positioning end 120 is provided with a second positioning part 121 and a second hook groove 1211. The first positioning hole 610 is connected to the first hook groove 1111, and the second positioning hole 620 is connected to the second hook groove 1211, for positioning the positioning film 600 to the bottom wall 100.

[0074] Specifically, in this embodiment, when the film applicator 500 is placed in the receiving space 400 of the screen film applicator, the film applicator 500 and the positioning film 600 are first bonded together. Then, the first positioning hole 610 of the positioning film 600 is hooked onto the first hook groove 1111, and the second positioning hole 620 of the positioning film 600 is hooked onto the second hook groove 1211, thereby achieving the positioning connection of the positioning film 600 on the screen film applicator, and thus indirectly achieving the positioning connection of the film applicator 500 on the screen film applicator. After the film applicator 500 and the display screen of the device to be filmed are firmly bonded, the first hook groove 1111 is removed from the first positioning hole 610, and the second hook groove 1211 is removed from the second positioning hole 620. At this time, the screen film applicator can be separated from the positioning film 600, and the positioning film 600 is still attached to the film applicator 500. The positioning film 600 can then be peeled off from the film applicator 500.

[0075] In this embodiment, the method of connecting the film applicator 500 to the screen protector device via the positioning film 600 facilitates precise positioning of the film applicator 500 on the screen protector device through the connection between the positioning film 600 and the screen protector device, ensuring a good fit between the film applicator 500 and the display screen of the device to be protected. Furthermore, the positioning film 600 also protects the surface of the film applicator 500, preventing it from being scratched during the screen protector application process.

[0076] In some embodiments, refer to Figure 6 The positioning film 600 includes a plurality of first positioning holes 610 and a plurality of second positioning holes 620. The first positioning end 110 includes a plurality of first positioning portions 111, and the second positioning end 120 includes a plurality of second positioning portions 121. The first positioning holes 610 and the first positioning portions 111 are correspondingly arranged, and the second positioning holes 620 and the second positioning portions 121 are correspondingly arranged. The distance between two adjacent first positioning portions 111 and the distance between two adjacent second positioning portions 121 are not equal.

[0077] Specifically, in this embodiment, the cooperative connection between the multiple first positioning parts 111 and the multiple first positioning holes 610, and the cooperative connection between the multiple second positioning parts 121 and the multiple second positioning holes 620, helps to improve the connection stability of the positioning film 600 on the screen film application device, thereby indirectly improving the connection stability of the film application component 500 on the screen film application device. This ensures that after the screen film application device and the display screen of the device to be filmed are fixed together, that is, after the film application component 500 and the display screen of the device to be filmed are aligned, the film application component 500 will no longer shift, thus improving the film application effect between the film application component 500 and the display screen of the device to be filmed.

[0078] Furthermore, since the film applicator 500 is not perfectly symmetrical, if it is applied backwards, it will cause a mismatch between the film applicator 500 and the display screen of the device to be covered, affecting the screen covering effect. In this embodiment, the distance between two adjacent first positioning parts 111 and the distance between two adjacent second positioning parts 121 are not equal. Correspondingly, the distance between two adjacent first positioning holes 610 and the distance between two adjacent second positioning holes 620 are also not equal. When connecting the positioning film 600 to the screen covering device, the positioning film 600 can only be connected to the screen covering device after the first positioning holes 610 and the first positioning parts 111 are aligned, and the second positioning holes 620 and the second positioning parts 121 are aligned. By adopting the above installation structure, the installation and positioning method of the positioning film 600 on the screen covering device is uniquely determined, avoiding the situation where the positioning film 600 is installed backwards on the screen covering device, and thus avoiding the situation where the film applicator 500 is installed backwards on the screen covering device.

[0079] Furthermore, in some embodiments, the first positioning part 111 and the second positioning part 121 can have different shapes and structures. For example, the first positioning part 111 can be a cylindrical structure, and the second positioning part 121 can be a square structure. Correspondingly, the first positioning hole 610 can be a circular hole, and the second positioning hole 620 can be a square hole. Using the above-described mounting structure, the mounting and positioning method of the positioning film 600 on the screen protector device can also be uniquely determined, avoiding the situation where the positioning film 600 is installed backwards on the screen protector device, and thus avoiding the situation where the screen protector 500 is installed backwards on the screen protector device.

[0080] In some embodiments, refer to Figure 1 , Figure 4 and Figure 6 At least one of the first positioning end 110 and the second positioning end 120 is provided with a third positioning part 112, which is used to position the tear-off part 511 of the release film 510.

[0081] Specifically, in this embodiment, by using the third positioning part 112 to position the tear-off part 511 of the release film 510, the alignment between the film applicator 500 and the display screen of the device to be filmed can also be indirectly ensured, thus ensuring the adhesion effect between the film applicator 500 and the display screen of the device to be filmed after the release film 510 is removed, and preventing the film applicator 500 from being misaligned.

[0082] In some embodiments, refer to Figure 1 , Figure 4 and Figure 6 The bottom wall 100 is provided with an elastic element 420 (exemplarily, for example, the elastic element 420 can be silicone, cotton strip, foam, etc.), the elastic element 420 and the side of the film-applying component 500 away from the release film 510 are in contact, for applying the film-applying component 500 to the display screen of the device to be filmed.

[0083] Specifically, referring to the above embodiment, since there is a tear gap between the film applicator 500 and the display screen of the device to be covered, after the release film 510 is removed, an external force is needed to press the film applicator 500 onto the display screen of the device to be covered, so that the film applicator 500 and the display screen of the device to be covered are adhered. In this embodiment, an elastic member 420 is provided in the accommodating space 400 to contact the film applicator 500. The elastic member 420 applies an elastic force to the film applicator 500. After the release film 510 is removed, the contact point between the film applicator 500 and the elastic member 420 is pressed onto the display screen of the device to be covered, so that the contact point between the film applicator 500 and the elastic member 420 is first adhered to the display screen of the device to be covered, and air is gradually released from the contact point between the film applicator 500 and the elastic member 420 towards both ends, so that the film applicator 500 is finally adhered to the display screen of the device to be covered, completing the screen covering operation.

[0084] During the process of applying the film to the display screen of the device to be covered, air is gradually expelled from both ends, thus squeezing out air bubbles between the film applicator 500 and the display screen, ensuring a good adhesion between them. Furthermore, the elastic element 420 is made of a soft material, which prevents it from scratching the film applicator 500 when it comes into contact with it.

[0085] In some embodiments, refer to Figure 1 , Figure 4 and Figure 6 The elastic element 420 is located at the center of the accommodating space 400.

[0086] Specifically, in this embodiment, the elastic element 420 is positioned at the center of the accommodating space 400, which ensures that the exhaust distance to both ends is the same when the film-applying component 500 and the display screen of the device to be film-applied are applied. At this time, the film-applying efficiency is the fastest, and the force at both ends is relatively uniform, resulting in the best film-applying effect.

[0087] In some embodiments, refer to Figure 1 , Figure 4 and Figure 6 Along the direction from the first sidewall 200 to the second sidewall 300, the first sidewall 200 has a first claw 210 corresponding to the elastic member 420. For example, if the first sidewall 200 has three first claws 210, the middle first claw 210 and the elastic member 420 are aligned.

[0088] Alternatively, along the direction from the first sidewall 200 to the second sidewall 300, the second sidewall 300 has a second claw 310 corresponding to the elastic member 420. For example, if the second sidewall 300 has three second claws 310, the middle second claw 310 is aligned with the elastic member 420.

[0089] Specifically, in this embodiment, there is a first claw 210 or a second claw 310 that corresponds to the position of the elastic member 420. When the first claw 210 or the second claw 310 is engaged on the display screen of the device to be covered, the first claw 210 or the second claw 310 can provide support for the elastic member 420, so that the elastic member 420 can apply an elastic force to the film-applying component 500, causing the film-applying component 500 and the display screen of the device to be covered to adhere.

[0090] In some embodiments, refer to Figure 1 , Figure 4 and Figure 6 The bottom wall 100 is provided with an observation hole 700.

[0091] Specifically, in this embodiment, the adhesion between the film applicator 500 and the display screen of the device to be filmed can be observed through the observation hole 700, so that the user can make timely adjustments to the film applicator 500.

[0092] It should be noted that other aspects of the screen protector device disclosed in this utility model can be found in the prior art, and will not be repeated here.

[0093] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
