High-performance screen protector applicator and screen protector application components for electronic devices Technical Field
[0001] This invention relates to the field of electronic device accessories, and in particular to a film applicator with good film application effect and an electronic device film application assembly. Background Technology
[0002] Nowadays, mobile phones have become indispensable electronic products in people's lives. In particular, the advent of smartphones has greatly changed people's lifestyles. With the development of smartphones, the screens of mobile phones are getting bigger and the phones are getting thinner. This directly leads to the screens being very easy to scratch or break during use, affecting the display effect and aesthetics. In daily use, mobile phones generally have a screen protector applied to the screen. This can protect the screen without affecting the appearance and use of the phone. Due to the wide range of applications of screen protectors, almost all smartphones, especially large-screen phones, have screen protectors applied.
[0003] Screen protector applicators are usually accessories included with screen protectors, typically a positioning frame or component, used to help users position the phone and screen protector correctly. Most current screen protector applicators first use the positioning frame to position the phone and screen protector. After positioning, the screen protector needs to be peeled off to remove the release liner before applying the protector. This method can lead to the phone screen being exposed, attracting dust and causing blisters. Furthermore, the lack of a limiting structure when peeling off the screen protector can cause the phone to shift during application, affecting the application result and leading to application failure.
[0004] Therefore, a new technical solution needs to be researched to address the above problems. Technical solutions
[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a film applicator and electronic device film application assembly with good film application effect. Through the design of a limiting member, which is detachably set on the main body of the film applicator, the device is positioned to limit the electronic device to be filmed, thus preventing the electronic device to be filmed from shifting.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A screen protector with good film application effect includes a screen protector body and a limiting member for preventing the electronic device to be covered from shifting.
[0008] The film applicator body has a placement slot for placing electronic device film and electronic device to be filmed, and a film outlet communicating with the placement slot; one of the film applicator body and the limiting member is provided with a docking position, and the other is provided with a docking part for cooperating with the docking position. The limiting member is detachably provided on the film applicator body, so that the docking part is adapted to the docking position.
[0009] As a preferred embodiment, the docking position is recessed downward from the upper edge of the film applicator body, and the docking position is connected to the placement groove; the docking part extends from the lower end face of the limiting member.
[0010] As a preferred embodiment, the docking position is further recessed with a snap-fit groove; one side of the docking part extends with a snap-fit part for fitting the snap-fit groove, and the limiting member is detachably installed on the body of the film applicator so that the snap-fit part fits the snap-fit groove.
[0011] As a preferred embodiment, the limiting member is further provided with a limiting part for pressing the electronic device when applying the film. The limiting part extends from the lower end of the limiting member and is located on the side of the docking part. When the limiting member is installed on the main body of the film applicator, the limiting part is located in the placement groove.
[0012] As a preferred embodiment, the limiting part is annular.
[0013] As a preferred embodiment, the peripheral side of the placement groove is provided with positioning protrusions for engaging the tempered glass film.
[0014] As a preferred embodiment, the end of the film applicator body away from the film outlet is also provided with a positioning notch that communicates with the placement groove, and a positioning protrusion for connecting the positioning hole is provided in the positioning notch.
[0015] As a preferred embodiment, a cotton strip is also adhered to the placement groove to facilitate air venting of the tempered glass film during application.
[0016] As a preferred embodiment, the film applicator with good film application effect also includes a housing, the housing having a mounting plate and a cover plate, the main body of the film applicator being disposed on the mounting plate, and the cover plate being detachably connected to the mounting plate.
[0017] An electronic device screen protector assembly includes a screen protector applicator and an electronic device screen protector. The screen protector applicator is any of the screen protectors described above that provides good screen protector application. The electronic device screen protector is suspended and fixed in a base. The electronic device screen protector includes a main film body and a release film attached to one side of the main film body. The release film includes a positioning end and a handle end. The positioning end has a positioning hole corresponding to the positioning protrusion, and the handle end extends out of the film outlet.
[0018] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly achieves the limiting effect through the design of the limiting component, which is detachably set on the body of the film applicator. In this way, the electronic device to be filmed is limited and prevented from shifting. Secondly, one of the film applicator body and the limiting component is provided with a mating position and the other with a mating part, so that the mating part is adapted to the mating position. In this way, the connection between the limiting component and the film applicator body is ensured through the cooperation of the mating part and the mating position.
[0019] Finally, the pull-out film application structure allows for easy and quick application. The electronic device is placed in the slot, positioning the film and the device. The user then pulls the handle extending from the film opening to separate the main film and release film, allowing the main film to adhere to the screen of the electronic device. This eliminates the need to peel off the film assembly, keeping both the electronic device and the film in the slot to prevent dust accumulation and ensure proper placement. It also prevents the film from shifting, guaranteeing a good application result. Attached Figure Description
