Description

Technical Field

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

[0002] Almost everyone owns an electronic device like a smartphone. During use, phone screens are easily scratched. Since smartphones have a relatively long lifespan, replacing the screen multiple times after a scratch is not cost-effective. Therefore, screen protectors, which are much cheaper than phone screens, have become an essential accessory for users. Currently, a number of consumers prefer to buy screen protector kits and apply them themselves. However, with traditional methods, after peeling off the release liner, the entire screen protector makes contact with the phone screen. Due to improper handling or uneven phone placement, some parts of the screen protector may not make complete contact, creating air bubbles and resulting in a failed application. This requires reapplication, and screen protectors are generally meant to be applied correctly the first time; once removed, they cannot be reused.

[0003] Later, a compact, one-handed screen protector applicator appeared on the market. It includes a substrate, with a limiting frame fixed along the perimeter of the substrate. The substrate and the limiting frame together form a receiving groove to accommodate the phone to which the screen protector is to be applied. The substrate is located on the bottom surface of the receiving groove and has venting grooves along its length. This venting groove design allows for application from the center outwards while venting air, enabling the screen protector to adhere automatically to the phone screen. However, this type of screen protector applicator has the following drawbacks:

[0004] Because its venting groove is on the same plane as the substrate, when the user presses the back of the substrate with their palm during the film application process, the vertical pressure is applied to the venting groove without any buffer. The palm press will directly squeeze the air in the venting groove, causing the air bubbles that have not been completely expelled to be discharged from the venting groove in advance. The remaining air bubbles at the edges and corners form trapped air, thus affecting the film application effect.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a mobile phone screen protector applicator. Through the design of an anti-accidental touch step, the anti-accidental touch step forms a cavity with the back of the back panel, creating a physical barrier between the anti-accidental touch step and the venting groove. This constitutes a surrounding barrier to the venting groove. When the palm presses down, the pressure is preferentially applied to the anti-accidental touch step and cannot be directly transmitted to the venting groove, preventing the user's palm from directly contacting the venting groove during pressing. This avoids premature venting when the air bubbles are not aligned, thereby improving the screen protector application effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A mobile phone screen protector applicator includes an applicator body; the applicator body includes a back plate portion and a frame portion; the back plate portion has a front side and a back side disposed opposite to each other; the front side and the frame portion of the back plate portion form a receiving groove for installing a mobile phone and a screen protector.

[0009] The back plate is provided with an exhaust groove for sliding exhaust, which extends along the long axis of the back plate. The back of the back plate is provided with an anti-accidental contact step along its circumference, which forms a cavity with the back of the back plate, so that the anti-accidental contact step and the exhaust groove form a physical barrier boundary.

[0010] As a preferred embodiment, the anti-accidental touch step includes a first protrusion, a second protrusion, a third protrusion, and a fourth protrusion. The first protrusion, the second protrusion, the third protrusion, and the fourth protrusion are connected to form a circumferential annular anti-accidental touch step, forming a closed "protective wall" to prevent the palm from accidentally touching the exhaust slide from any direction. The annular protrusion also distributes the palm pressure to four directions, avoiding accidental triggering of the exhaust slide due to local overload.

[0011] As a preferred embodiment, the circumferential annular anti-accidental touch step is arranged circumferentially around the outer contour of the back plate.

[0012] As a preferred embodiment, the back of the back plate is further provided with a first reinforcing rib, which is located around the venting groove to enhance the structural stability of the applicator.

[0013] As a preferred embodiment, a second reinforcing rib is provided at the periphery of the receiving groove near the exhaust slide to enhance the structural stability of the film applicator.

[0014] As a preferred embodiment, the main body of the film applicator is also provided with a film outlet for the pull strip to pass through.

[0015] As a preferred embodiment, the frame portion is provided with a limiting post on the side facing the receiving groove to limit the tempered glass film, thereby improving the film application quality.

[0016] As a preferred embodiment, the main body of the film applicator is made of blister material.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly improves the application effect by designing an anti-accidental touch step. The back of the back panel is provided with an anti-accidental touch step along its circumference. The anti-accidental touch step and the back of the back panel form a cavity, so that the anti-accidental touch step and the exhaust groove form a physical barrier boundary. In this way, it forms a surrounding barrier for the exhaust groove. When the palm presses, the pressure is preferentially applied to the anti-accidental touch step and cannot be directly transmitted to the exhaust groove, preventing the user's palm from directly contacting the exhaust groove when pressing, avoiding premature exhaust when the air bubble is not aligned, thereby improving the film application effect.

[0018] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0034] A mobile phone screen protector applicator includes an applicator body 1.

[0035] Preferably, the body 1 of the film applicator is made of blister material. The body 1 of the film applicator is integrally injection molded.

[0036] The screen protector body 1 includes a back plate portion 11 and a frame portion 12; the back plate portion 11 has a front and a back side disposed opposite to each other; the front side of the back plate portion 11 and the frame portion 12 form a receiving groove 13 for mounting the mobile phone and the screen protector 4.

[0037] The back plate 11 is provided with an exhaust groove 14 for sliding exhaust, which extends along the long axis of the back plate 11; the back of the back plate 11 is provided with an anti-accidental contact step 2 protruding in its circumferential direction, and the anti-accidental contact step 2 and the back of the back plate 11 form a cavity, so that a physical barrier boundary 3 is formed between the anti-accidental contact step 2 and the exhaust groove 14.

[0038] Preferably, the anti-accidental touch step 2 includes a first protrusion 21, a second protrusion 22, a third protrusion 23, and a fourth protrusion 24. The first protrusion 21, the second protrusion 22, the third protrusion 23, and the fourth protrusion 24 are connected to form a circumferential annular anti-accidental touch step 2, forming a closed "protective wall" to prevent the palm from accidentally touching the exhaust groove 14 from any direction. The annular protrusions distribute the palm pressure to four directions, avoiding accidental triggering of the exhaust groove 14 due to local overload. The cavity formed by the annular barrier and the back plate 11 provides a buffer space for the palm, so that the exhaust groove 14 will not be squeezed even when pressed at multiple angles. The symmetrical layout of the annular protrusions conforms to ergonomics, and the palm naturally fits the annular edge. There is no need to deliberately adjust the angle when pressing, which is suitable for users with different hand shapes.

[0039] When applying the film, the palm presses on any position of the ring step, and the pressure is evenly distributed through the four protrusions. Due to the buffering effect of the cavity, the pressure cannot be transmitted to the middle exhaust groove 14. Only when the scraper pushes the air bubble along the long axis will the air bubble be discharged along the exhaust groove 14, thus achieving precise exhaust control.

[0040] Preferably, the circumferentially annular anti-accidental contact step 2 is arranged circumferentially around the outer contour of the back plate portion 11. Preferably, a first reinforcing rib 111 is also provided on the back side of the back plate portion 11, and the first reinforcing rib 111 is located at the periphery of the exhaust groove 14 to enhance the structural stability of the film applicator. Preferably, a second reinforcing rib 131 is provided in the receiving groove 13 near the periphery of the exhaust groove 14 to enhance the structural stability of the film applicator.

[0041] Preferably, the main body 1 of the film applicator is further provided with a film outlet 15 for the pull strip to pass through. The protective film 4 includes a release film and a tempered glass film stacked vertically. The protective film 4 is inserted into the receiving groove 13. The front and rear ends of the release film are adhered to the front surface of the back plate 11, and the rear end of the release film extends at least partially beyond the film outlet 15. The front and rear ends of the release film are adhered to the back plate 11 by adhesive.

[0042] Preferably, the frame portion 12 is provided with a limiting post for limiting the tempered glass film on the side facing the receiving groove 13, which is used to limit the tempered glass film and improve the film application quality.

[0043] The key design feature of this invention is the use of an anti-accidental touch step. The back of the back panel has an anti-accidental touch step protruding circumferentially, forming a cavity with the back of the back panel. This creates a physical barrier between the anti-accidental touch step and the venting groove, thus encircling the venting groove. When the palm presses down, the pressure is preferentially applied to the anti-accidental touch step and cannot be directly transmitted to the venting groove. This prevents the user's palm from directly contacting the venting groove during pressing, avoiding premature venting when the air bubble is not aligned, thereby improving the film application effect.

[0044] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
