[0034] Embodiment 1

[0035] like Figure 1 and 2 As shown, a vehicle-mounted touch cover with imitation wood grain effect comprises:

[0036] A protective cover 10;

[0037] A light-transmissive imitation wood grain decorative layer 20 is disposed on the back side of the protective cover plate 10;

[0038] A light shielding functional layer 30 is disposed on the back of the imitation wood grain decorative layer 20 and is provided with a plurality of button hollow patterns 31;

[0039] The touch function layer 40 is disposed on the back side of the light shielding function layer 30 , and is provided with a plurality of touch buttons 41 , and one touch button 41 corresponds to one button hollow pattern 31 .

[0040] The vehicle-mounted touch cover of the utility model is provided with a light-transmissive imitation wood grain decorative layer 20 between the protective cover 10 and the light-shielding functional layer 30. The imitation wood grain decorative layer 20 is used to provide the vehicle-mounted touch cover with an imitation wood grain base color, so that the base color of the vehicle-mounted touch cover is consistent with the imitation wood grain decorative panel of the center console, thereby improving the aesthetics of the automobile center console; and the light-shielding functional layer 30 is provided with a key hollow pattern 31, and each touch key 41 is illuminated by backlight when in use. Since the imitation wood grain decorative layer 20 is light-transmissive, the backlight can be seen by the user through the key hollow pattern 31 and the imitation wood grain decorative layer 20 in turn, so that the user can identify the position and function of each touch key 41 through the position and shape of each key hollow pattern 31.

[0041] Preferably, the light transmittance of the imitation wood grain decorative layer 20 is between 40% and 60%.

[0042] A plurality of annular grooves 11 are disposed on the front surface of the protective cover plate 10 , one annular groove 11 corresponds to one key hollow pattern 31 , and each annular groove 11 surrounds the outer periphery of the corresponding key hollow pattern 31 .

[0043] The annular groove 11 is mainly used to improve the user's feel when operating the vehicle-mounted touch cover plate, and the uneven touch can provide feedback when the user operates the vehicle-mounted touch cover plate.

[0044] like Figure 3 The imitation wood grain decorative layer 20 includes a first transparent substrate 21 , an imitation wood grain decorative pattern 22 and a second transparent substrate 23 . The imitation wood grain decorative pattern 22 is sandwiched between the first transparent substrate 21 and the second transparent substrate 23 .

[0045] In this embodiment, the imitation wood grain decorative pattern 22 is an imitation wood grain ink, which can be formed on the surface of the second transparent substrate 23 by screen printing or inkjet printing, and then the first transparent substrate 21 is glued and fixed to the side surface of the second transparent substrate 23 where the imitation wood grain decorative pattern 22 is formed, so as to seal the imitation wood grain decorative pattern 22 and prevent the imitation wood grain decorative pattern 22 from being eroded by water vapor and deforming the grain.

[0046] The imitation wood grain ink, also known as imitation wood grain paint, is a special water-based art paint, which is mainly used to create realistic imitation wood grain effects. It does not contain harmful elements such as organic volatiles, free formaldehyde and heavy metals, is environmentally friendly, harmless to the human body, and has rich colors and textures. It can provide a variety of color options, such as more than 20 commonly used color cards, and supports customized colors to meet different wood grain requirements with a high degree of simulation.

[0047] The first transparent substrate 21 faces the protective cover plate 10 and is preferably a PMMA substrate. The second transparent substrate 23 faces away from the protective cover plate 10 and is preferably a PMMA substrate or an ABS substrate.

[0048] In this embodiment, the imitation wood grain decorative layer 20 is bonded and fixed to the back of the protective cover plate 10 by OCA optical glue 24. The OCA optical glue 24, full name Optically Clear Adhesive, is a special adhesive used to bond transparent optical elements. It belongs to a type of pressure-sensitive adhesive and has the characteristics of colorless transparency, high light transmittance, and high adhesion. The OCA optical glue 24 has high clarity and a total light transmittance of more than 99%, which ensures high light transmittance. The bonding strength of the OCA optical glue 24 is good, which can ensure a tight connection between optical elements. The OCA optical glue 24 has excellent weather resistance and water resistance, and will not cause yellowing, peeling and deterioration problems after long-term use. The OCA optical glue 24 can be cured at room temperature or medium temperature, and has small curing shrinkage, which is suitable for use at various ambient temperatures. The OCA optical glue 24 can resist the erosion of ultraviolet rays and maintain long-term stability and reliability.

[0049] like Figure 4As shown, the shading functional layer 30 includes a black ink 32 arranged on the back of the imitation wood grain decorative layer 20, and a reverse cover ink 33 arranged on the back of the black ink 32, the key hollow pattern 31 is arranged in the black ink 32, and the reverse cover ink 33 fills the key hollow pattern 31 of the black ink 32.

[0050] Preferably, the OD value (absorbance) of the black ink 32 should be guaranteed to be above 4 to achieve the light-shielding effect. The thickness of the black ink 32 is between 1.5-1.9 μm, and there are at least two layers. If the light-shielding property of the material of the black ink 32 is low, the thickness of the black ink 32 can be appropriately increased. If the light-shielding property of the material of the black ink 32 is high, the thickness of the black ink 32 can be appropriately reduced, and the present invention should not be limited thereto.

[0051] The black ink 32 uses carbon black as a colorant, which is mixed in an ink base material and formed on the back of the imitation wood grain decorative layer 20 through a silk screen printing process. It has the characteristics of high density, high viscosity, high hiding power, etc. It has good printability, can be printed on various substrates, and has good weather resistance and durability.

[0052] The reverse cover ink 33 is mainly used to fill the vacuum inside the black ink 32 and the burrs on the edge, further preventing the black ink 32 from leaking light; the reverse cover ink 33 is also used to fill the unevenness on the surface of the black ink 32 to facilitate the subsequent production of the touch function layer 40.

[0053] Preferably, the reverse cover ink 33 is a semi-transparent ink with a transmittance between 40% and 60%, mainly to reduce the transmittance of each key hollow pattern 31, so as to improve the consistency of the imitation wood grain decorative layer 20 at each key hollow pattern 31 and at other positions when each touch key 41 is not illuminated by the backlight.

[0054] like Figure 5-7 As shown, the touch function layer 40 includes multiple touch electrodes 42, a common ground line 43, multiple touch pins 44 and a ground pin 45, one touch pin 44 corresponds to one touch electrode 42, and each touch pin 44 is arranged on the back side of the corresponding touch electrode 42; the common ground line 43 surrounds the periphery of each touch electrode 42, and the ground pin 45 is arranged on the back side of the common ground line 43; each touch electrode 42 and its peripheral common ground line 43 constitute a corresponding touch button 41.

[0055] During assembly, the center console is provided with a metal probe at the installation position of the vehicle-mounted touch cover panel. After the vehicle-mounted touch cover panel is assembled and fixed in the center console, the metal probe abuts against the touch pin 44 and the ground pin 45 to be conductive, thereby electrically connecting the touch electrode 42 and the common ground wire 43 to the control main board of the center console.

[0056] Preferably, the touch electrodes 42 and the common ground wire 43 are made of conductive silver paste, and the touch pins 44 and the ground pins 45 are made of conductive carbon paste.

[0057] The touch functional layer 40 uses conductive silver paste to make the touch electrode 42 and the common ground line 43, and uses conductive carbon paste to make the touch pin 44 and the ground pin 45. The conductive silver paste and the conductive carbon paste are both in a fluid state before curing, and can be formed into various complex patterns by screen printing like ink to reduce the overall thickness of the touch functional layer 40; and the friction resistance of the conductive carbon paste is better than that of the conductive silver paste. The touch pin 44 and the ground pin 45 made of conductive carbon paste are respectively arranged on the back of the touch electrode 42 and the common ground line 43 made of conductive silver paste, which can improve the wear resistance of the touch functional layer 40 when it is in contact with the external control circuit.

[0058] In this embodiment, the protective cover plate 10 is made of tempered glass.

[0059] Embodiment 2

[0060] As an optimization solution of the first embodiment, in this embodiment, if Figure 8 As shown, the vehicle-mounted touch cover further includes a backlight layer 60 , and the backlight layer 60 is disposed on the back side of the touch function layer 40 .

[0061] The backlight layer 60 is used to light up each touch button 41 when the vehicle-mounted touch cover is in use, and can be, but is not limited to, an LED light bar or an OLED light bar.

[0062] The backlight layer 60 may have a total light-emitting area, which covers all the touch keys 41, so that all the touch keys 41 are lit up at the same time when in use; the backlight layer 60 may also have multiple sub-light-emitting areas, one sub-light-emitting area corresponds to one touch key 41, so that each touch key 41 can be lit up individually when in use.

[0063] Embodiment 3

[0064] As an optimization solution of Embodiment 1 or Embodiment 2, in this embodiment, if Fig. 9 As shown, the vehicle-mounted touch cover further includes a light diffusion layer 50 , and the light diffusion layer 50 is disposed on the back side of the touch function layer 40 (ie, between the touch function layer 40 and the backlight layer 60 ).

[0065] The light diffusion layer 50 is used to disperse the backlight emitted by the backlight layer 60 to make it more uniform, and can be, but is not limited to, a light diffusion film.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them.
