Description

Technical Field

[0001] The present application relates to the field of switch panels, and in particular to an ink scratch-resistant panel. Background Art

[0002] The layer structure of the membrane switch consists of multiple parts, which are divided into four main parts: panel, surface adhesive layer, circuit layer and back adhesive layer. The panel is generally made of high-toughness PET or PC transparent colorless sheet with printed patterns and texts, and its main function is to serve as a logo and button. The panel consists of a base layer and an ink layer. The text pattern is printed on the upper surface of the base layer, and the ink layer is bonded and fixed to the lower surface of the base layer. The ink layer is a black opaque layer and is bonded and fixed to the circuit layer. The ink layer can play a light-shielding role, so that the light in the circuit layer illuminates the base layer from the designated area.

[0003] Currently, refer to Figure 1 When the panel is used for a mechanical push switch, the panel needs to be bonded and fixed to the switch housing 10. A plurality of push slots 11 are provided in the housing 10. A button 13 is fixedly installed in each push slot 11 of the housing 10 through a connecting block 12. The connecting block 12 has a certain flexibility. When the button 13 is pressed, the button 13 moves in the push slot 11 through the connecting block 12, thereby triggering the switch. A hole 14 is provided on the side of each button 13 of the housing 10. The light of the switch can be emitted from the hole 14, thereby judging the switch state of the button 13. A plurality of irregularly arranged bumps 15 are integrally formed on the side of each button 13 of the housing 10.

[0004] The ink layer of the panel is bonded and fixed to the surface of the shell and the buttons. Since the button will move back and forth in the pressing groove each time the button is pressed, the ink layer at the button is easily scratched by the button after long-term use, causing the ink layer to fall off from the base layer. At this time, air permeability will appear in the panel, affecting the aesthetics of the panel. Utility Model Content

[0005] In order to improve the problem that the ink layer of the panel is prone to falling off, the present application provides an ink scratch-resistant panel.

[0006] The ink anti-scratch panel provided in this application adopts the following technical solution:

[0007] An ink scratch-proof panel comprises a base layer and an ink layer, wherein the ink layer is bonded to the lower surface of the base layer, an ink protection layer is provided on the lower surface of the ink layer, and an adhesive layer for bonding and fixing to a switch housing is provided on the lower surface of the ink protection layer.

[0008] By adopting the above technical solution, the base layer, the ink layer and the ink protective layer constitute the main structure of the panel, and the adhesive layer bonds the ink protective layer to the switch housing, thereby installing the panel on the switch housing. When the panel is pressed, the ink protective layer separates the ink layer from the switch button and protects the ink layer, so that the ink layer at the button is not easily scratched and the ink layer is not easily separated from the base layer.

[0009] Preferably, the ink protection layer includes a pressing portion and an adhesive portion, the pressing portion and the adhesive portion are integrally formed, the pressing portion is convexly arranged and affixed to the key, the adhesive portion is planar, and the adhesive layer is arranged on the adhesive portion.

[0010] By adopting the above technical solution, the adhesive layer adheres and fixes the ink protective layer to the switch housing through the adhesive part, and the pressing part of the pressing panel presses the key. The pressing part of the ink protective layer and the key are only in a fitting relationship, and are not adhesively fixed. Therefore, the ink layer at the key is not easy to fall off during the process of pressing the key.

[0011] Preferably, the base layer and the ink layer are both convexly arranged at the pressing portion of the ink protection layer.

[0012] By adopting the above technical solution, the base layer and the ink layer are convexly arranged at the pressing part, so that the ink layer and the ink protective layer fit more closely, and the base layer and the ink protective layer clamp the ink layer, thereby making it difficult for the ink layer to fall off.

[0013] Preferably, a first light-transmitting hole is formed on the base layer at the hole of the switch housing.

[0014] By adopting the above technical solution, the light of the switch can be emitted from the hole, and the light emitted from the hole can be emitted from the base layer through the first light-transmitting hole, so that it is convenient for users to judge the state of the key switch.

[0015] Preferably, a second light-transmitting hole is provided on the ink layer at the hole of the switch housing, the second light-transmitting hole is provided coaxially with the first light-transmitting hole, and the aperture of the second light-transmitting hole is larger than the aperture of the first light-transmitting hole.

[0016] By adopting the above technical solution, the light of the switch can be emitted from the hole, and the light emitted from the hole can emit the ink layer from the second light-transmitting hole. The aperture of the second light-transmitting hole is larger than the aperture of the first light-transmitting hole, so that the light emitted from the hole is displayed in a larger area on the base layer, which is more convenient for users to identify.

[0017] Preferably, the ink protection layer is formed with a plurality of convex hulls at the plurality of convex points of the switch housing, and the plurality of convex hulls correspond one-to-one to the plurality of convex points of the switch housing.

[0018] By adopting the above technical solution, when bonding the panel, the multiple protrusions of the ink protection layer are matched with the multiple protrusions of the shell, so that the installation position of the panel can be quickly located, making the panel bonding more accurate.

[0019] Preferably, a transparent protective layer is provided on the upper surface of the base layer.

[0020] By adopting the above technical solution, the transparent protective layer protects the base layer without affecting the viewing of the font pattern on the base layer, so that the font pattern on the base layer is not easily damaged.

[0021] Preferably, the transparent protective layer is convexly arranged at the pressing portion, and the surface of the transparent protective layer at the convexly arranged portion is provided with anti-slip patterns.

[0022] By adopting the above technical solution, the anti-slip pattern increases the friction between the user's fingers and the transparent protective layer, thereby making it easier for the user to press the panel.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The ink layer is protected by the ink protection layer. When the panel is pressed, the ink protection layer separates the ink layer from the switch button and protects the ink layer, so that the ink layer at the button is not easy to fall off from the base layer;

[0025] 2. With the help of the pressing part and the bonding part, the bonding layer bonds and fixes the ink protective layer to the switch housing through the bonding part, and the pressing part of the pressing panel presses the key. The pressing part of the ink protective layer and the key are only in a fitting relationship, and are not bonded and fixed, so that the ink layer at the key is not easy to fall off during the process of pressing the key;

[0026] 3. By adopting the outward convex setting of the base layer and the ink layer at the pressing part, the ink layer and the ink protective layer are more closely fitted, and the base layer and the ink protective layer clamp the ink layer, so that the ink layer is not easy to fall off.
