Description

Technical Field

[0001] This application relates to the field of display screen protective film technology, and in particular to a protective film structure and a touch switch panel. Background Technology

[0002] Currently, the manual touch switch panel of the tank control machine mainly consists of a circuit board that can identify resistance and a PVC film, enabling the switch panel to receive and respond to manually input commands while displaying various parameter information. When the operator touches a button with their finger, the switch panel sends a specific signal to the tank control machine, thereby controlling the corresponding indicator light to turn on or off and the start or stop of the external actuator.

[0003] In related technologies, due to the extremely high frequency of use of manual touch switch panels, a protective film is usually applied to the touch switch panel to prevent the buttons from wearing out. However, in actual production activities, frequently used buttons such as "clear" suffer particularly severe wear and damage, often resulting in situations where frequently used buttons are severely worn while other buttons remain intact. In such cases, replacing the entire protective film due to the wear of one or two buttons would obviously be wasteful. Utility Model Content

[0004] This application provides a protective film structure and a touch switch panel, which can solve the problem of waste caused by replacing the entire protective film due to wear and tear on one or two buttons.

[0005] On one hand, this application provides a protective film structure, which includes a protective film, a first release film, and a plurality of second release films. The protective film is provided with a plurality of first easy-tear lines and a plurality of second easy-tear lines. The plurality of first easy-tear lines extend along a first direction and are arranged in parallel and spaced apart. The plurality of second easy-tear lines extend along a second direction and are arranged in parallel and spaced apart. The first direction and the second direction intersect each other. The plurality of first easy-tear lines and the plurality of second easy-tear lines intersect each other in sequence, dividing the protective film into a plurality of sub-protective films. The first release film is disposed on one side of the protective film, and the plurality of second release films are disposed on the side of the protective film opposite to the first release film. The plurality of second release films correspond one-to-one with the plurality of sub-protective films.

[0006] Optionally, in some embodiments, each of the sub-protective films has a protrusion on the side facing away from the first release film.

[0007] Optionally, in some embodiments, the protrusion has an identifier on the side facing away from the first release film.

[0008] Optionally, in some embodiments, the outer surface of the marker is provided with a wear-resistant and corrosion-resistant coating.

[0009] Optionally, in some embodiments, the second release film is provided with clearance holes, and the protrusion is located in the clearance holes.

[0010] Optionally, in some embodiments, the thickness of the protrusion is greater than the thickness of the sub-protective film, and the thickness of the protrusion is greater than or equal to 0.4 mm and less than or equal to 1 mm, and the thickness of the sub-protective film is greater than or equal to 0.3 mm and less than or equal to 0.6 mm.

[0011] Optionally, in some embodiments, the protrusion includes at least one of polycarbonate, fluorocarbon resin, silicone, and polyimide.

[0012] Optionally, in some embodiments, the first release film has a first gripping strip on its side, one end of which extends outside the protective film; and / or, the second release film has a second gripping strip on its side, one end of which extends outside the sub-protective film.

[0013] Optionally, in some embodiments, the thickness of the first release film and the second release film are equal, and the thickness of the first release film and the second release film is greater than or equal to 0.2 mm and less than or equal to 0.4 mm.

[0014] On the other hand, embodiments of this application provide a touch switch panel, which includes a protective film structure as described above and a plurality of button portions, with each of the sub-protective films attached to the corresponding button portion.

[0015] The technical advantages of the protective film structure and touch switch panel provided in this application embodiment are as follows: By setting multiple first tear lines and multiple second tear lines on the protective film, with the multiple first tear lines extending along a first direction and the multiple second tear lines extending along a second direction, the first and second directions intersecting, and the multiple first tear lines arranged in parallel intervals, and the multiple second tear lines also arranged in parallel intervals, the multiple first tear lines and multiple second tear lines can intersect sequentially, thereby dividing the protective film into multiple sub-protective films. A first release film is set on one side of the protective film, and multiple second release films can be respectively set on the side of the multiple sub-protective films opposite to the first release film. The sub-protective films can be separated from the first release film along the first tear lines or the second tear lines, and then the sub-protective films can be attached to the buttons on the touch switch panel. The second release films on the sub-protective films can then be peeled off. When the sub-protective films on the buttons are worn out, only the old sub-protective films on the buttons need to be replaced with new ones, without replacing the entire protective film, saving time, effort, and maintenance costs.

[0028] On the one hand, please refer to Figures 1 to 3 This application provides a protective film structure, which is mainly used to be attached to a touch switch panel to protect the buttons on the touch switch panel and prevent the buttons from being damaged during long-term use.

[0029] Specifically, the protective film structure includes a protective film 1, a first release film 4, and a second release film 5. The protective film 1 is square in shape, and may have multiple first easy-tear lines 2 and multiple second easy-tear lines 3, with the multiple first easy-tear lines 2 extending along a first direction. Figure 1 The X-axis direction is the first direction, and the multiple first tear lines 2 can be arranged in parallel intervals in sequence. That is to say, the multiple first tear lines 2 extend along the X-axis direction and are arranged in intervals along the Y-axis direction.

[0030] Multiple second tear lines 3 are all provided extending along a second direction, and the second direction intersects with the first direction. Figure 1The Y-axis direction is the second direction, and multiple second tear lines 3 can also be arranged in parallel intervals. That is to say, multiple second tear lines 3 extend along the Y-axis direction and are arranged in intervals along the X-axis direction, so that multiple first tear lines 2 and multiple second tear lines 3 intersect in sequence. More clearly, multiple first tear lines 2 and multiple second tear lines 3 form a mesh structure, and multiple first tear lines 2 and multiple second tear lines 3 divide the protective film 1 into multiple sub-protective films 11. The shape of the sub-protective films 11 can also be square.

[0031] Combination Figure 1 and Figure 3 The shape of the first release film 4 is the same as that of the whole protective film 1, and the size of the first release film 4 can be greater than or equal to the size of the whole protective film 1, so that when the first release film 4 is set on one side of the protective film 1, it can completely cover the whole protective film 1. The shape of the second release film 5 is the same as that of the sub-protective film 11, and the size of the second release film 5 can be less than or equal to the size of the sub-protective film 11, so that multiple second release films 5 can be respectively set on the side of multiple sub-protective films 11 away from the first release film 4.

[0032] When using the protective film 1, the sub-protective film 11 can be separated from the first release film 4 along the first easy-tear line 2 or the second easy-tear line 3, and then the sub-protective film 11 can be attached to the buttons on the touch switch panel. One sub-protective film 11 can be attached to each button on the touch switch panel, and then the second release film 5 on each sub-protective film 11 can be peeled off. When the sub-protective film 11 on the frequently used buttons is worn out, you only need to replace the old sub-protective film 11 on the frequently used buttons with a new one. There is no need to replace the entire protective film 1, which saves time, effort and maintenance costs.

[0033] Please see Figure 1 and Figure 3 In some embodiments, each sub-protective film 11 may have a protrusion 6 on the side opposite to the first release film 4.

[0034] Specifically, in this embodiment, the protrusion 6 is circular in shape. In other embodiments, the protrusion 6 may also be square in shape. When the sub-protective film 11 needs to be pasted onto the button surface, the protrusion 6 can serve as a reference point to help the user to position and align more accurately, ensuring that the sub-protective film 11 can cover the correct position. In addition, the protrusion 6 can also provide additional protection by adding a layer of protection to areas that are easily impacted or worn.

[0035] Please see Figure 1 and Figure 3 In some embodiments, the protrusion 6 has an identifier 7 on the side opposite to the first release film 4.

[0036] Specifically, when there are multiple sub-protective films 11 of different types or functions, the identification element 7 can serve as a mark to distinguish them. Through different identification elements 7, users can easily identify and select the required protective film 1. The identification element 7 can also contain information such as text, symbols or patterns to correspond to the functions of the buttons, which can intuitively display the function of each button on the touch switch panel and help users quickly understand and operate the touch switch panel.

[0037] In some embodiments, the outer surface of the marking element 7 is provided with a wear-resistant and corrosion-resistant coating.

[0038] Specifically, the wear-resistant coating protects the surface of the label 7 from friction and wear, especially in high-frequency use environments such as touch switch panels, where the wear-resistant coating effectively extends the service life of the label 7. Even with prolonged and frequent touching or pressing, the text, symbols, or patterns on the label 7 remain clear and are not easily worn away.

[0039] The anti-corrosion coating can prevent the marking component 7 from being corroded and oxidized by chemicals. Especially in harsh environments such as humidity and corrosive gases, the anti-corrosion coating can protect the marking component 7 from corrosion and maintain its appearance and functional integrity.

[0040] Please see Figure 1 and Figure 2 In some embodiments, the second release film 5 may be provided with clearance holes, and the size and shape of the clearance holes are matched with the size and shape of the protrusion 6 to ensure that the protrusion 6 can be smoothly inserted into the hole and remain stable. By providing clearance holes, the second release film 5 can be easily attached to the sub-protective film 11.

[0041] Please see Figure 1 and Figure 3 In some embodiments, the thickness of the protrusion 6 is greater than the thickness of the sub-protective film 11, wherein the thickness of the protrusion 6 is greater than or equal to 0.4 mm and less than or equal to 1 mm, while the thickness of the sub-protective film 11 is greater than or equal to 0.3 mm and less than or equal to 0.6 mm.

[0042] Specifically, the thickness of the sub-protective film 11 is between 0.3 mm and 0.6 mm, ensuring sufficient flexibility and fit. This thickness range allows the sub-protective film 11 to easily adapt to various surface shapes and provide good protection.

[0043] Furthermore, since the thickness of the protrusion 6 is between 0.4mm and 0.6mm, and the thickness of the protrusion 6 is greater than that of the sub-protective film 11, the protrusion 6 can provide better cushioning and protection. Especially when subjected to external impact or pressure, the protrusion 6 is particularly suitable for areas that require extra protection, such as the button parts on the touch switch panel that are easily pressed or worn.

[0044] In some embodiments, the protrusion 6 comprises at least one of polycarbonate, fluorocarbon resin, silicone and polyimide.

[0045] Specifically, firstly, polycarbonate is a thermoplastic with high strength, high transparency, good heat resistance and impact resistance, which can resist external impacts, protect the sub-protective film 11 from damage, and maintain a clear appearance.

[0046] Secondly, fluorocarbon resins have excellent weather resistance, corrosion resistance and self-cleaning properties, and can remain stable for a long time in harsh environments. They are not easily corroded by chemicals and are very suitable for outdoor or high humidity environments.

[0047] Furthermore, silicone material is soft and elastic, with a comfortable feel, and has good temperature resistance and chemical stability, which can provide better cushioning and protect the protective film 11 from deformation or breakage under pressure.

[0048] Finally, polyimide is a high-performance engineering plastic with excellent high-temperature resistance, radiation resistance, and mechanical properties. It can maintain stable performance even at high temperatures, making it suitable for some special working environments.

[0049] Taking into account the properties of the above materials, the appropriate material can be selected to make the protrusion 6 according to the specific application scenario and requirements. For example, polycarbonate can be selected for applications requiring high transparency and impact resistance; fluorocarbon resin can be selected for applications requiring good weather resistance and corrosion resistance; silicone can be selected for applications requiring a soft touch and cushioning effect; and polyimide is an ideal choice for applications requiring high temperature stability.

[0050] Please see Figure 1 and Figure 3 In some embodiments, the side of the first release film 4 may be provided with a first gripping strip 41, and one end of the first gripping strip 41 may extend outside the protective film 1. Similarly, the side of the second release film 5 may be provided with a second gripping strip 51, and one end of the second gripping strip 51 may extend outside the sub-protective film 11.

[0051] Specifically, the presence of the first gripping strip 41 and the second gripping strip 51 makes it easier for users to grip and manipulate the first release film 4 and the second release film 5, especially when they need to be removed from the protective film 1 or the sub-protective film 11. The first gripping strip 41 and the second gripping strip 51 provide additional gripping area and stability, allowing users to locate the starting point of the tear more quickly, making the operation easier and more accurate.

[0052] Please see Figure 1 and Figure 2 In some embodiments, the thickness of the first release film 4 and the thickness of the second release film 5 are equal, and the thickness of the first release film 4 and the thickness of the second release film 5 are greater than or equal to 0.2 mm and less than or equal to 0.4 mm.

[0053] Specifically, the first release film 4 and the second release film 5 within this thickness range can provide moderate peeling force, which is neither too thin to be difficult to peel, nor too thick to increase the difficulty of peeling, so that users can easily and smoothly complete the operation when removing the release film.

[0054] Furthermore, by controlling the thickness of the first release film 4 and the second release film 5 within the range of 0.2mm to 0.4mm, the functional requirements can be met while avoiding the use of thicker materials that would increase costs, thus helping to maximize the cost-effectiveness of the product.

[0055] On the other hand, this application embodiment also provides a touch switch panel, which includes the protective film structure as described above and a plurality of button portions, each of the sub-protective films 11 being attached to the corresponding button portion.

[0056] Specifically, the beneficial effects of the touch switch panel in this embodiment are the same as those of the protective film structure, and will not be repeated here.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
