The present disclosure relates to a protective member and an electronic equipment.
In an electronic equipment having a display, a protective film is attached to a surface of the display in order to prevent scratches and dirt from adhering to the surface of the display.
According to the present disclosure, an object of the present disclosure is to provide a protective member and an electronic equipment that properly operate push-type switch while properly avoiding deterioration of a visibility and appearance of a display surface by attaching a protective film to a surface of a front panel of the electronic equipment.
According to one aspect of the present disclosure, a protective film having a base material layer and an adhesive layer to which an adhesive is applied to the base material layer, and a separator that is attached to the entire side of the adhesive layer before using the protective film and is attached to the entire surface of the adhesive layer before the protective film is used and that partly peels off from the adhesive layer and the rest does not peel off when the protective film is used are provided. When the protective film is attached to a display surface provided on the overlay cover is provided with the display surface and a surface of a front panel where a top surface of a push plate of a push-type switch is exposed from an opening of the overlay cover, the protective film is attached to the surface of the front panel so that the adhesive layer is not adhered to the surface of the overlay cover and the adhesive layer is not adhered to the upper surface of the push plate of the push-type switch and a periphery of the upper surface.
According to one aspect of the present disclosure, a front panel and a protective film are provided, the front panel has a display surface on the overlay cover and the upper surface of the push plate of the push-type switch is exposed from the opening, and the protective film has a base material layer and an adhesive layer which is adhesive attached to the base material layer. The protective film is attached to the surface of the front panel so that the adhesive layer is adhered to a part of the surface of the overlay cover and the adhesive layer is not adhered to the upper surface of the push plate of the push-type switch and the periphery of the upper surface.
The above and other objects, features and advantages of the present disclosure will become more apparent from the following detailed description made with reference to the accompanying drawings. In the drawings:
In an assumable example, an electronic device having a display, has a configuration in which a protective film is attached to a display surface in order to prevent scratches and dirt from adhering to the display surface. The protective film has a base material layer made of a transparent and flexible resin and an adhesive layer in which an adhesive is applied to an entire one side of the base material layer. Before use, a separator is attached to the entire surface of the adhesive layer. When the protective film is used, the separator is peeled off from the adhesive layer to expose the adhesive layer, and the exposed adhesive layer is adhered to the display surface.
For example, in a center display device arranged on a dashboard of the vehicle, a part of a transparent overlay cover is used as a screen display portion, and the display surface is arranged so as to face the screen display portion. At the same time, a push-type switch that can be pressed by an user may be arranged around the surface of the display. In this case, an opening is formed in the overlay cover, and the upper surface of the push plate of the push-type switch is exposed from the opening to form the front panel. In such a configuration, the adhesive layer adheres to the entire surface of the front panel, so that the protective film is attached to the screen display portion to prevent scratches and dirt from adhering to the screen display portion, and it is possible to avoid deterioration of visibility and appearance of the display surface.
In the configuration in which the adhesive layer is adhered to the entire surface of the front panel, the adhesive layer is adhered not only to the screen display portion but also to the upper surface of the push plate of the push-type switch and the periphery of the upper surface. Therefore, there is a concern that the push plate cannot be pressed due to the tension of the protective film. Further, even if the push plate can be pressed, there is a concern that the push plate does not return to the original position due to the adhesive force of the protective film.
According to the present disclosure, an object of the present disclosure is to provide a protective member and an electronic equipment that properly operate push-type switch while properly avoiding deterioration of a visibility and appearance of a display surface by attaching a protective film to a surface of a front panel of the electronic equipment.
According to one aspect of the present disclosure, a protective film having a base material layer and an adhesive layer to which an adhesive is applied to the base material layer, and a separator that is attached to the entire side of the adhesive layer before using the protective film and is attached to the entire surface of the adhesive layer before the protective film is used and that partly peels off from the adhesive layer and the rest does not peel off when the protective film is used are provided. When the protective film is attached to a display surface provided on the overlay cover is provided with the display surface and a surface of a front panel where a top surface of a push plate of a push-type switch is exposed from an opening of the overlay cover, the protective film is attached to the surface of the front panel so that the adhesive layer is not adhered to the surface of the overlay cover and the adhesive layer is not adhered to the upper surface of the push plate of the push-type switch and a periphery of the upper surface.
Since the adhesive layer is adhered to a part of the surface of the overlay cover, and the protective film is adhered to the surface of the front panel, it is possible to appropriately avoid deterioration of the visibility and appearance of the display surface. Since the adhesive layer is prevented from adhering to the upper surface of the push plate of the push-type switch and the periphery of the upper surface, the tension and the adhesive force of the protective film do not act, and the push-type switch can be operated appropriately. As a result, the protective film is attached to the surface of the front panel of the electronic device, so that the push-type switch can be operated appropriately while appropriately avoiding deterioration of the visibility and appearance of the display surface.
According to one aspect of the present disclosure, a front panel and a protective film are provided, the front panel has a display surface on the overlay cover and the upper surface of the push plate of the push-type switch is exposed from the opening, and the protective film has a base material layer and an adhesive layer which is adhesive attached to the base material layer. The protective film is attached to the surface of the front panel so that the adhesive layer is adhered to a part of the surface of the overlay cover and the adhesive layer is not adhered to the upper surface of the push plate of the push-type switch and the periphery of the upper surface.
Since the protective film is attached to the surface of the front panel of the electronic device, the push-type switch can be operated appropriately while appropriately avoiding deterioration of the visibility and appearance of the display surface.
Hereinafter, an embodiment will be described with reference to the drawings.

On the display surface 4, for example, a map screen for a navigation function, a setting screen for an audio function, a setting screen for an air conditioner function, and the like are displayed, and various touch buttons are displayed on each screen. In the overlay cover 7, the screen display portion 8a has a capacitance type touch sensor, and when the user touches a portion of the screen display portion 8a corresponding to the touch button, the touch operation is detected. The rotary switch is, for example, a volume switch for adjusting the volume, a tune switch for selecting a radio receiving station, or the like. The push-type switch is, for example, a switch for selecting or determining various items.
When the front panel 3 is attached to the main body of the device, the operation knobs 5a and 5b of the rotary switch project forward (in an occupant direction) from the surface 7a of the overlay cover 7, and the display surface 4 and the upper surface of the push plates 6a to 6f of the push-type switch are substantially flush with the surface 7a of the overlay cover 7. The term “substantially flush” as used herein means not only a perfect same plan but also a state in which the display surface 4 and the upper surfaces of the push plates 6a to 6f of the push-type switch are slightly recessed or convex from the surface 7a of the overlay cover 7. Further, the surface 7a of the overlay cover 7 is not a perfect flat surface but has a slightly curved shape, and has a curved structure that is slightly convex in the vertical direction and slightly convex in the horizontal direction.
In a manufacturing process and a delivery process until the vehicle reaches the user, a protective film is attached to the surface 3a of the front panel 3 on the vehicle manufacturer side in order to prevent scratches and dirt from adhering to the screen display portion 8a facing the display surface 4. After the user purchases the vehicle, a protective film may be attached by the user himself/herself in order to prevent scratches and dirt from adhering to the screen display portion 8a facing the display surface 4.
Hereinafter, the protective film will be described. As shown in
The protective film 10 has a base material layer 12 and an adhesive layer 13 on which an adhesive is applied to the entire surface of the base material layer 12. The base material layer 12 is a layer that is exposed to the outside in a state where the protective film 10 is attached to the surface 3a of the front panel 3. That is, the base material layer 12 is a layer that actually protects the display surface 4 from scratches and dirt. The adhesive layer 13 is a layer to which the separator 11 is attached before using the adhesive layer 13 and a part of the separator 11 is peeled off at the time of use, and is a layer in which a part of the separator 11 from which the separator 11 has peeled off is attached to the surface 7a of the overlay cover 7.
The base material layer 12 is made of a transparent and flexible resin. That is, with the protective film 10 attached to the surface 3a of the front panel 3, the display surface 4 and the upper surfaces of the push plates 6a to 6f of the push-type switch can be visually recognized, and the base material layer 12 bends when the upper surfaces of the push plates 6a to 6f are pressed. Examples of the resin used for the base material layer 12 include silicon resin, olefin resin, PET (Poly Ethylene Terephthalate) resin and the like.
The adhesive layer 13 is made of a transparent adhesive so that the display surface 4 and the upper surfaces of the push plates of the push-type switches 6a to 6f can be visually recognized when the protective film 10 is attached to the surface 3a of the front panel 3. Further, the adhesive layer 13 is preferably made of an adhesive having high adhesion when the separator 11 is attached and easily peelable when the separator 11 is peeled off. Examples of the adhesive used for the adhesive layer 13 include an acrylic adhesive, a silicon adhesive, etc.
The separator 11 is attached to the adhesive layer 13 before the protective film 10 is used, and as described above, only a part of the separator 11 is peeled off from the adhesive layer 13 when the protective film 10 is used. If the adhesive layer 13 is exposed before the use of the protective film 10, the adhesive strength is reduced. Therefore, the separator 11 is attached to the adhesive layer 13 in order to avoid the reduction in the adhesive strength.
In the present embodiment, as described above, when the protective film 10 is used, the entire part of the separator 11 is not peeled off from the adhesive layer 13, but only a part of the separator 11 is peeled off from the adhesive layer 13. Therefore, a slit is formed so that the portion to be peeled off from the adhesive layer 13 can be easily peeled off. That is, the separator 11 is separated into a portion that is peeled off from the adhesive layer 13 by the slit and a portion that remains without being peeled off. More specifically, as shown in
Like the base material layer 12, the separator 11 is also made of a transparent and flexible resin. That is, with the protective film 10 attached to the surface 3a of the front panel 3, the display surface 4 and the upper surfaces of the push plates 6a to 6f of the push-type switch can be visually recognized, and the separator 11 bends when the upper surfaces of the push plates 6a to 6f are pressed. However, if the base material layer 12 has a certain level of strength, the separator 11 does not need to be as strong as the base material layer 12. Examples of the resin used for the separator 11 include an alkyl resin and a silicon resin.
As shown in
When the push plate 17 is not pressed, the upper surface 17a of the push plate 17 and the surface 7a of the overlay cover 7 are substantially flush with each other as described above, an electrical contacts are open, and the tact switch 18 is in a off state. When a pressing force from above is applied to the push plate 17, the upper surface 17a of the push plate 17 is recessed from the surface 7a of the overlay cover 7, and the rubber 21 is moved to the base 22 side, so that the electrical contacts becomes from the open state to the close state. The tact switch 18 is turned on. When the pressing force applied to the push plate 17 is released, the upper surface 17a of the push plate 17 that is recessed from the surface 7a of the overlay cover 7 returns to an original position, and the rubber 21 that has been moved to the base 22 side returns to the original position. The electrical contacts return from the closed state to the open state, and the tact switch 18 returns to the off state.
Next, a mode in which the protective film 10 is attached to the surface 3a of the front panel 3 will be described. As shown in
In the adhesive layer 13 of the protective film 10, the upper left and right portions from which the separator 11 is peeled off are adhered to the surface 7a of the overlay cover 7. Further, in the adhesive layer 13 of the protective film 10, the central portion and the left and right lower portions where the separator 11 remains without being peeled off are not adhered to the surface 7a of the overlay cover 7.
When the protective film 10 is attached to the surface 3a of the front panel 3, the portions S1 and S2 shown in
By adhering a part of the adhesive layer 13 to the surface 7a of the overlay cover 7 in this way, the protective film 10 can be attached to the surface 3a of the front panel 3. As shown in
Further, the separator 11 remains without being peeled off in the state where the protective film 10 is attached in this way. Therefore, as shown in
When the surface 7a of the overlay cover 7 has a curved structure, and the planar protective film 10 is attached to the surface 7a of the overlay cover 7, the shape of the curved surface 7a of the overlay cover 7 and the shape of the flat protective film 10 does not match, and the protective film 10 floats. Therefore, there is a concern that air bubbles or wrinkles may be generated. In the present embodiment, as compared with the case where the entire adhesive layer 13 is adhered, only a part of the adhesive layer 13 is adhered and the area where the adhesive layer 13 is adhered is small, so that the generation of air bubbles and wrinkles can be suppressed. That is, the larger the area to which the adhesive layer 13 is adhered, the more air bubbles and wrinkles may be generated. However, in the present embodiment, the area to which the adhesive layer 13 is adhered is reduced so that the generation of air bubbles and wrinkles can be suppressed. As a result, it is possible to prevent the appearance from being deteriorated due to the generation of bubbles and wrinkles.
The present embodiment as described above produces the following technical effects. Since the adhesive layer 13 is adhered to a part of the surface 7a of the overlay cover 7, and the protective film 10 is adhered to the surface 3a of the front panel 3, it is possible to appropriately avoid deterioration of the visibility and appearance of the display surface 4. Since the adhesive layer 13 is prevented from adhering to the upper surface 17a of the push plate 17 of the push-type switch 16 and the periphery of the upper surface 17a, the tension and the adhesive force of the protective film 10 do not act, and the push-type switch 16 can be operated appropriately. As a result, the protective film 10 is adhered to the surface 3a of the front panel 3 to prevent scratches and dirt from adhering to the screen display portion 8a. The push-type switch 16 can be appropriately operated while appropriately avoiding deterioration of the visibility and appearance of the display surface 4.
Further, as compared with the case where the adhesive layer 13 is adhered to the entire surface 7a of the overlay cover 7, it is possible to reduce the area where adhesive residue may occur when the protective film 10 adhered to the surface 7a of the overlay cover 7 is peeled off. As a result, it is possible to prevent deterioration of the appearance due to the generation of adhesive residue.
Further, when the decoration method is different between the surface 7a of the overlay cover 7 and the upper surface 17a of the push plate 17 of the push-type switch 16, in a configuration in which the adhesive layer 13 is adhered to the upper surface 17a of the push plate 17 and the periphery of the upper surface 17a, it is necessary to evaluate the resistance to the adhesive layer 13 and the adhesive residue resistance for both the surface 7a of the overlay cover 7 and the upper surface 17a of the push plate 17. On the other hand, the resistance to the adhesive layer 13 and the resistance to adhesive residue may be evaluated only on the upper surface 17a of the push plate 17. Therefore, it is possible to reduce the development cost and development period, and to improve the development efficiency.
Further, since the adhesive layer 13 is prevented from adhering not only to the upper surface 17a of the push plate 17 of the push type switch 16 and the periphery of the upper surface 17a thereof but also to the screen display portion 8a facing the display surface 4, it is also possible to appropriately avoid deterioration of the visibility and appearance of the display surface 4 due to the generation of bubbles and wrinkles.
Further, the adhesive layer 13 is adhered to the surface 7a of the overlay cover 7 at two opposite locations in the left-right direction. For example, when the right end of the protective film 10 is held by the right hand and the left end is held by the left hand and the protective film 10 is adhered to the surface 3a of the front panel 3, it becomes easy to evenly adjust the left-right balance and it is possible to improve a workability when the protective film 10 is adhered.
Further, conventionally, the protective film 10 can be attached only after confirming the operation of the push-type switch 16 in the manufacturing process or the inspection process, and therefore, there is concern that scratches and dirt would adhere to the screen display portion 8a in the manufacturing process or the inspection process. However, in the present embodiment, the protective film 10 can be attached even before the operation of the push-type switch 16 is confirmed, and it is possible to appropriately prevent scratches and dirt from adhering to the screen display portion 8a in the manufacturing process and the inspection process. It is also possible to increase the degree of freedom in the procedure of the manufacturing process and the inspection process. Further, when it becomes necessary to check the operation of the push-type switch 16 after the protective film 10 is attached, it has been necessary to partially peel off the protective film 10 in some case, but in the present embodiment, it is not necessary to partially peel off the protective film 10.
Although the present disclosure has been described in accordance with the examples, it is understood that the present disclosure is not limited to such examples or structures. The present disclosure encompasses various modifications and variations within the scope of equivalents. Additionally, various combinations and configurations, as well as other combinations and configurations including more, less, or only a single element, are within the scope and spirit of the present disclosure.
The electronic equipment is not limited to the center display device 2, and may be another in-vehicle device. Further, it may be an electronic equipment for other purposes other than the in-vehicle use.
The layout and number of rotary switches and push switches are arbitrary. The layout, shape, area ratio, etc. of the portion peeled from the adhesive layer 13 and the portion remaining without being peeled from the adhesive layer 13 may be determined in the separator 11 according to the layout and number of push-type switches.
Although the configuration in which the display surface 4 is covered by the screen display portion 8a of the overlay cover 7 on the surface 3a of the front panel 3 is illustrated, the configuration in which the display surface 4 is exposed may be possible.
