Technical Field
[0001] This utility model relates to the field of electronic device accessories technology, and in particular to a film application device and film application assembly. Background Technology
[0002] Mobile phones, tablets, and other electronic devices have gradually become indispensable items in people's daily lives. Taking mobile phones as an example, due to the high frequency of use, screen scratches often occur. To prevent this, people apply a protective film to the screen. To improve the application effect, a screen protector applicator is usually used.
[0003] Existing screen protector applicators require a positioning structure to fix the protective film onto the applicator. However, most of these positioning structures are raised on the upper surface of the applicator, which increases the thickness of the applicator. Furthermore, the excessive protrusion can easily scratch the user. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, the present invention provides a film application device and film application assembly, which changes the position of the lifting part and the fixing part by means of the first platform part and the second platform part, so as to ensure the height of the lifting part while avoiding the fixing part from protruding too much.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A protective film applicator includes a base with a recessed receiving groove on its upper surface for placing an electronic device. A protective film assembly is fixed above the base. The upper surface of the base has a first platform portion and a second platform portion, the second platform portion being located on the side of the first platform portion away from the receiving groove. The vertical distance between the upper surface of the first platform portion and the bottom surface of the base is greater than the vertical distance between the upper surface of the second platform portion and the bottom surface of the base. The base has a fixing portion for fixing the protective film assembly to the base and a lifting portion for maintaining a fixed distance between the protective film assembly and the electronic device in the height direction of the base. The fixing portion protrudes upward from the second platform portion, and the upper surface of the first platform portion constitutes the lifting portion.
[0007] In one embodiment of this utility model, along the height direction of the base, the maximum distance between the fixing part and the bottom surface of the base is not greater than the maximum distance between the lifting part and the bottom surface of the base.
[0008] In one embodiment of the present invention, the base has a length direction, and along the length direction of the base, the fixing part is on the side of the raised part away from the receiving groove.
[0009] In one embodiment of the present invention, the fixing part includes a fixing post and a limiting protrusion for fixing the protective film assembly. The fixing post protrudes upward from the second platform part, and the limiting protrusion protrudes outward from the side of the fixing post.
[0010] In one embodiment of the present invention, the limiting protrusion has a limiting surface facing the bottom surface of the base, and the distance between the limiting bearing surface and the bottom surface of the base is not less than 10mm.
[0011] In one embodiment of this utility model, the upper surface edge of the fixing column is rounded or chamfered.
[0012] In one embodiment of the present invention, the first platform portion and the second platform portion are connected by an inclined surface.
[0013] In one embodiment of the present invention, the lifting portion includes a contact surface that abuts against the protective film assembly, and the edge of the contact surface has an arc-shaped transition.
[0014] A film-applying assembly is also provided, including the film-applying device described above, and further including a film-pressing module and a protective film assembly disposed between the base and the film-pressing module, wherein the protective film assembly includes a protective film and a positioning film;
[0015] The film pressing module is slidably engaged with the base. The sliding direction of the film pressing module relative to the base is the sliding direction. The film pressing module is used to press the protective film located between the film pressing module and the electronic device onto the electronic device. The base includes a first base and a second base located on opposite sides of the receiving groove along the sliding direction. The sliding position of the film pressing module includes a starting position and an ending position. The starting position is located on the side of the receiving groove closer to the first base, and the ending position is located on the side of the receiving groove closer to the second base. The lifting part is disposed on the second base.
[0016] In one embodiment of the present invention, the first base is provided with an elastic positioning part for lifting the protective film assembly, and the distance from the bottom of the receiving groove to the highest point of the elastic positioning part is greater than the thickness of the electronic device; the two ends of the positioning film maintain a fixed distance from the electronic device through the lifting part and the elastic positioning part.
[0017] The beneficial effects of this utility model are: by changing the positions of the lifting part and the fixing part through the first platform part and the second platform part, the height of the lifting part is ensured while avoiding excessive protrusion of the fixing part. Separating the positioning structures makes height control of the fixing part easier to achieve. Furthermore, the spaced design between the first and second platforms forms a "lift-fix" mechanism, ensuring the height difference between the protective film and the base, guaranteeing initial positioning accuracy before fixing the protective film.

[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
[0025] Reference Figures 1 to 4This utility model provides a screen protector application device, which may specifically include, for example, a base 1. The upper surface of the base 1 is provided with a receiving groove 11 for placing electronic devices such as mobile phones or tablets. The shape and size of the receiving groove 11 can, for example, match the electronic device, so that when the electronic device is placed in the receiving groove 11, it can be better fixed and will not easily move. The lifting part 12 includes a contact surface that abuts against the protective film assembly 3. Along the thickness direction of the base 1, the distance from the bottom of the receiving groove 11 to the contact surface is greater than the thickness of the electronic device. The protective film assembly 3 is positioned on the base 1 and covers the electronic device within the receiving groove 11. The base 1 positions the electronic device and the protective film, allowing the protective film to be accurately applied to the screen of the electronic device.
[0026] The upper surface of the base 1 is provided with a first platform portion 101 and a second platform portion 102. The first platform portion 101 and the second platform portion 102 are disposed on the same side of the receiving groove 11, and the second platform portion 102 is disposed on the side of the first platform portion 101 away from the receiving groove 11. The vertical distance between the upper surface of the first platform portion 101 and the bottom surface of the base 1 is greater than the vertical distance between the upper surface of the second platform portion 102 and the bottom surface of the base 1.
[0027] The base 1 is provided with a fixing part 13 for fixing the protective film assembly 3 to the base 1 and a lifting part 12 for maintaining a fixed distance between the protective film assembly 3 and the electronic device in the height direction of the base 1. The positioning structure is set separately, making it easier to control the height of the fixing part 13.
[0028] The fixing part 13 protrudes upward from the surface of the second platform part 102, forming a protruding positioning structure, while the flat surface of the first platform part 101 constitutes the lifting part 12, serving as the area for lifting the protective film. Since the second platform part 102 is lower than the first platform part 101, excessive protrusion of the fixing part 13 is avoided. Furthermore, the spacing between the first and second platforms creates a "lift-fix" mechanism, ensuring a fixed height difference between the protective film and the surface of the electronic device, preventing premature contact between the protective film and the electronic device surface, thus avoiding any impact on the application effect.
[0029] Preferably, along the height direction of the base 1, the maximum distance between the fixing part 13 and the bottom surface of the base 1 is not greater than the maximum distance between the lifting part 12 and the bottom surface of the base 1. The upper surface of the fixing part 13 is controlled to be lower than the upper surface of the lifting part 12 to avoid the fixing part 13 from protruding excessively, thereby reducing the risk of scratching the user.
[0030] The base 1 is a cuboid structure with a length direction and a width direction. The receiving groove 11 also has a length direction and a width direction and is arranged parallel to the length direction and width direction of the base 1. Similarly, the protective film is a rectangular film, and its length direction is also arranged along the length direction of the base 1.
[0031] Furthermore, along the length direction of the base 1, the fixing part 13 is located on the side of the lifting part 12 away from the receiving groove 11. That is, the lifting part 12 and the fixing part 13 form a "lifting-fixing" configuration along the length direction. The lifting part 12 and the fixing part 13 fix the protective film from the length direction of the protective film, thus avoiding the stretching of the protective film along its length direction and preventing the deformation of the protective film caused by the lateral stretching of the shorter protective film during fixing.
[0032] In one embodiment where the fixing part 13 secures the protective film assembly 3, the fixing part 13 includes a fixing post 131 and a limiting protrusion 132 for securing the protective film assembly 3. The fixing post 131 protrudes upward from the second platform, and the limiting protrusion 132 protrudes outward from the side of the fixing post 131, and is located on the side of the fixing post 131 away from the lifting part 12. When the limiting protrusion 132 protrudes outward, a limiting surface 133 facing the bottom of the base 1 is formed at its bottom. When the protective film assembly 3 is fitted onto the fixing part 13, the fixing post 131 limits the horizontal direction of the protective film assembly 3, while the limiting protrusion 132 limits the vertical direction of the protective film assembly 3, preventing the protective film assembly 3 from moving vertically and dislodging from the fixing post 131 when the lifting part 12 lifts it. The fixing part 13 can also be configured as a spring wall structure that can press and fix the protective film assembly 3, or a clamping structure that can clamp and fix the protective film assembly 3.
[0033] The limiting surface 133 restricts the position of the protective film assembly 3 on the base 1, wherein the distance between the limiting bearing surface and the bottom surface of the base 1 is not less than 10mm. This ensures that there is sufficient space below the limiting bearing surface, so that when the user grasps the protective film assembly 3 and hangs it on the fixing part 13, there is enough space for their fingers and they will not touch the table surface, causing inconvenience.
[0034] Furthermore, the upper surface edge of the fixing post 131 is rounded or chamfered to avoid the edge being too sharp and scratching the protective film assembly 3 when installing the protective film, and also to prevent the protruding fixing post 131 from scratching the user.
[0035] To provide better support for the protective film assembly 3, an inclined plane 14 connects the first platform portion 101 and the second platform portion 102. The inclined plane 14 is a flat surface formed by the height difference between the first platform portion 101 and the second platform portion 102. The inclined plane 14 supports the section of the protective film assembly 3 from the lifting portion 12 to the fixing portion 13, preventing the protective film assembly 3 from being suspended due to the height difference between the two positions. If there is a suspended position, the protective film assembly 3 is easily damaged by external impacts.
[0036] Furthermore, the contact surface edge of the lifting part 12 is rounded to form an arc transition. This prevents the edge of the lifting part 12 from damaging the protective film assembly 3 when it supports it.
[0037] This utility model also provides a film pressing assembly, including the above-mentioned film applying device and film pressing module 2, and a protective film assembly 3 between the base 1 and the film pressing module 2. The protective film assembly 3 is placed on the base 1. The protective film assembly 3 may include, for example, a protective film, a release film, a pull strip, and a positioning film. The release film and the positioning film are located on opposite sides of the protective film. The pull strip is located on the side of the release film away from the protective film, and the release film is located on the side closer to the receiving groove 11. The pull strip is connected to the release film, and pulling the pull strip removes the release film. The positioning film is disposed on the side of the protective film away from the receiving groove 11. Both ends of the positioning film along the length direction are detachably fixed to the base 1, with one end hooked onto the fixing part 13. The protective film is pasted on the side of the positioning film facing the receiving groove 11. The protective film is located above the receiving groove 11 and its orthographic projection along the depth direction of the receiving groove 11 is within the range of the receiving groove 11. The shape and size of the protective film can, for example, match the screen of the electronic device. The protective film is suspended above the electronic device by the positioning film and is pasted onto the mobile phone screen by applying pressure.
[0038] The film pressing module 2 is positioned above the base 1 and slides on the base 1 to roll or squeeze the protective film, expelling air bubbles between the protective film and the electronic device. The base 1 has slide rails on both sides, and the film pressing module 2 slides back and forth on the base 1 in a sliding engagement with the slide rails, ensuring that the film pressing module 2 can move precisely along the predetermined trajectory of the slide rails during operation. The film pressing module 2 has a film pressing component located on the side of the film pressing module 2 facing the base 1. When the film pressing component slides into the receiving groove 11 as the film pressing module 2 slides, it can contact the protective film, thereby pressing the protective film onto the electronic device.
[0039] Furthermore, the base 1 includes a first base and a second base located on opposite sides of the receiving groove 11 along the sliding direction of the pressing module 2. The first base and the second base increase the overall structure of the base 1 and enhance its stability. The two ends of the slide rail extend to the first base and the second base respectively, ensuring that the slide rail passes through the receiving groove 11. The sliding position of the pressing module 2 is limited by the slide rail, and the two ends of the slide rail form the starting position and the ending position of the pressing module 2.
[0040] The starting position is located on the side of the receiving groove 11 near the first base, and the ending position is located on the side of the receiving groove 11 near the second base, ensuring that the film pressing module 2 can slide through the receiving groove 11. When the film pressing module 2 slides to the starting position, the projection of the film pressing component along the depth direction of the receiving groove 11 is located within the first base. This ensures that when the film pressing operation begins, the film pressing component can gradually apply pressure from the outer edge of the protective film, allowing for a smoother transition of the protective film during the bonding process and ensuring the bonding effect.
[0041] Both the first platform section 101 and the second platform section 102 are provided on the second base. The lifting section 12 is provided on the second base, which can ensure that the protective film at the end position is lifted. During the sliding pressing process of the pressing module 2, the end position of the protective film and the electronic device are kept in a gap to facilitate venting. When the pressing module 2 presses the protective film completely onto the electronic device, the gap between the protective film and the electronic device is eliminated.
[0042] Furthermore, an elastic positioning part is provided at the first base for lifting the protective film assembly 3. The distance from the bottom of the receiving groove 11 to the highest point of the elastic positioning part is greater than the thickness of the electronic device. The elastic positioning part can move up and down under the pressure of the film pressing module 2, which facilitates the film pressing module 2 to slide from the starting position to the ending position. And the two ends of the positioning film maintain a fixed distance from the electronic device through the lifting part 12 and the elastic positioning part.
[0043] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
