[0042] As Figure 1 shown, the present utility model provides an in-vehicle display screen 100. The in-vehicle display screen 100 includes a housing 10, a glass cover plate 20, a display panel 30, and a fixing plate 40. An accommodation space 11 is provided inside the housing 10. Opposite sides of the accommodation space 11 form a first opening and a second opening. The glass cover plate 20 is disposed at the first opening, the display panel 30 is disposed in the accommodation space 11. The display panel 30 includes a display layer 31 and a backlight layer 32. The display layer 31 is connected to the backlight layer 32, and the backlight layer 32 is located on the side of the display layer 31 away from the glass cover plate 20. The fixing plate 40 is disposed at the second opening. The fixing plate 40 is a part of the center console 210 (refer to Figure 5 ), the fixing plate 40 is detachably connected to the housing 10 and the center console 210, and the fixing plate 40 includes a fixing surface 41 facing the first opening. The fixing surface 41 is configured to be connected to the backlight layer 32. Here, the display layer 31 is located between the backlight layer 32 and the glass cover plate 20, the backlight layer 32 is located between the display layer 31 and the fixing plate 40, and the housing 10 is configured to surround the peripheries of the display layer 31 and the backlight layer 32.

[0043] In this embodiment, by setting the fixing surface 41 of the fixing plate 40 to be connected to the backlight layer 32 of the display panel 30, and connecting the side of the fixing plate 40 away from the fixing surface 41 to the center console 210, the multiple components of the display panel 30 are assembled on the fixing plate 40, and through the connection between the fixing plate 40 and the center console 210, the in-vehicle display screen 100 realizes the integration of the touch control assembly, avoiding the separate rear case for fixing the multiple structural components in the display panel 30, which causes structural redundancy in the in-vehicle display screen 100, thus avoiding the overlap in the structure of the in-vehicle display screen 100, reducing the overall thickness of the in-vehicle display screen 100, and at the same time being able to avoid the vibration hidden danger caused by more laminations, thereby improving the installation stability of the in-vehicle display screen 100.

[0044] In this embodiment, since the fixing plate 40 is detachably connected to the housing 10 and the center console 210, and the backlight layer 32 is connected to the fixing plate 40, and the display layer 31 is connected to the backlight layer 32, so that multiple structural components of the display panel 30 can be indirectly fixedly connected to the fixing plate 40, and the display panel 30 is connected to the center console 210 through the fixing plate 40, thereby reducing the material cost of the in-vehicle display screen 100 and realizing the assembly flexibility of the in-vehicle display screen 100. That is to say, in this embodiment, first the display layer 31 and the backlight layer 32 are connected to form the display panel 30, then the display panel 30 is fixedly connected to the fixing plate 40, and after the housing 10 and the glass cover 20 are assembled, the fixing plate 40 is connected to the housing 10 to form the in-vehicle display screen 100, and finally the in-vehicle display screen 100 is fixedly connected to the center console 210 through the fixing plate 40.

[0045] In this embodiment, the fixing plate 40 is hermetically connected to the housing 10, and the glass cover 20 is hermetically connected to the housing 10 to form a closed accommodation space 11, preventing dust or rainwater from entering the accommodation space 11 and causing the display panel 30 to be damp or contaminated, thereby improving the service life of the in-vehicle display screen 100.

[0046] In this embodiment, the glass cover 20 is arranged at the first opening of the housing 10 and is used to cooperate with the housing 10 and the fixing plate 40 to form a closed accommodation space 11. The glass cover 20 has a high impact resistance and can effectively prevent direct impact of external objects on the display screen, protecting the display screen from damage. At the same time, the glass cover 20 also has excellent wear resistance and can resist scratches and abrasions during daily use, maintaining the clarity and beauty of the display screen. In addition, the glass cover 20 has a high light transmittance, which can ensure that the images and colors of the display screen are presented truly and clearly, enhancing the visual experience of drivers and passengers. The glass cover 20 can also effectively prevent the attachment of fingerprints and stains, keep the screen clean, and improve the user experience.

[0047] In a further embodiment, the fixing plate 40 is made of magnesium alloy. In this embodiment, the fixing plate 40 made of magnesium alloy has extremely high strength, toughness and impact resistance, and can effectively resist external impacts and extrusion, protecting the multiple structural components in the internal display panel 30 from damage. This is particularly important for the in-vehicle display screen 100 because the vehicle 200 may encounter various complex road conditions and vibrations during driving. Since the density of magnesium alloy is much lower than that of steel and some traditional alloy materials, the overall weight of the in-vehicle display screen 100 can be reduced, thereby realizing the lightweight of the vehicle 200 display screen, improving the fuel economy of the vehicle and reducing energy consumption. At the same time, the fixing plate 40 made of magnesium alloy has good thermal conductivity and can quickly dissipate the heat generated by the display panel 30 to the outside of the housing 10, avoiding the heat of the rear shell of the display panel 30 in the prior art from being dissipated to the accommodation space 11 and then through the whole machine rear shell to the outside of the in-vehicle display screen 100, and avoiding the low heat dissipation efficiency of the in-vehicle display screen 100 caused by the structural overlap formed by the rear shell of the display panel 30 and the whole machine rear shell, thereby improving the heat dissipation efficiency of the in-vehicle display screen 100 structurally and maintaining the stable operation of the device.

[0048] In this embodiment, the fixing plate 40 made of magnesium alloy has light-blocking properties and can prevent light from being transmitted into the accommodation space 11 through the fixing plate 40, thereby ensuring the normal display function of the display panel 30.

[0049] As Figure 2 shown, in a further embodiment, the fixing plate 40 further includes a mounting frame 42 that protrudes from the fixing surface 41 toward the first opening. The mounting frame 42 is used to fix the display layer 31 and the backlight layer 32. In this embodiment, the mounting frame 42 is disposed in the accommodation space 11, and one end of the mounting frame 42 is fixedly connected to the fixing plate 40, so as to connect the display layer 31 and the pessimistic layer of the display panel 30 to the fixing plate 40 through a mounting bracket, thereby increasing the mounting stability of the display panel 30 and avoiding damage to the in-vehicle display screen caused by the separation of the display panel 30 and the fixing plate 40 due to the bumping of the vehicle 200.

[0050] In a further embodiment, the fixing plate 40 is formed by die-casting. In this embodiment, the fixing plate 40 is set to be formed by die-casting so that the fixing plate 40 can be adapted to the shape of the center console 210 to improve the degree of adaptation between the fixing plate 40 and the center console 210, thereby improving the mounting stability of the fixing plate 40.

[0051] As Figure 1As shown, in a further embodiment, the display panel 30 further includes a first adhesive layer 33, and the first adhesive layer 33 is located between the backlight layer 32 and the display layer 31. In this embodiment, the backlight layer 32 and the display layer 31 are connected through the first adhesive layer 33, which can achieve a tight connection between the display layer 31 and the backlight layer 32, prevent relative movement or separation between the backlight layer 32 and the display layer 31, and thus improve the structural stability of the entire display panel 30. At the same time, the tight connection between the display layer 31 and the backlight layer 32 can reduce the loss of light during transmission, improve the utilization efficiency of light, and thus make the display effect brighter and clearer.

[0052] In a further embodiment, the first adhesive layer 33 is an optical adhesive. In this embodiment, the first adhesive layer 33 is set as an optical adhesive, which can minimize the loss of light between the backlight layer 32 and the display layer 31 when passing through the first adhesive layer 33, so that the brightness, color saturation and contrast of the display panel 30 are significantly improved to enhance the display effect of the in-vehicle display screen 100. At the same time, the optical adhesive has excellent adhesive properties. Setting the first adhesive layer 33 as an optical adhesive can ensure a tight bond between the display layer 31 and the backlight layer 32, prevent interlayer separation or displacement caused by factors such as vibration and impact, and thus enhance the overall structural stability of the display panel 30. Here, the optical adhesive can be an optically clear adhesive or an optically clear resin.

[0053] As Figure 1 shown, in a further embodiment, the display panel 30 further includes a touch layer 34, which is located between the display layer 31 and the glass cover plate 20, and a second adhesive layer 35 is provided between the touch layer 34 and the display layer 31, and a third adhesive layer 36 is provided between the touch layer 34 and the glass cover plate 20. In this embodiment, both the second adhesive layer 35 and the third adhesive layer 36 are optical adhesives to achieve a tight connection between the touch layer 34 and the display layer 31 and between the touch layer 34 and the glass cover plate 20, prevent relative movement or separation between the various structural components in the display panel 30, and thus improve the structural stability of the entire display panel 30. At the same time, setting the second adhesive layer 35 and the third adhesive layer 36 as optical adhesives can minimize the loss of light, so that the brightness, color saturation and contrast of the display panel 30 are significantly improved to enhance the display effect of the in-vehicle display screen 100. Here, the touch layer 34 is used to sense the touch actions transmitted by the user through the glass cover plate 20, so as to display the corresponding screen content.

[0054] Figure 6 It is a schematic internal structure diagram of an in-vehicle display screen according to another embodiment of the present invention.

[0055] As Figure 6As shown, in a further embodiment, the in-vehicle display screen 100 further includes a fourth adhesive layer 50, which is located between the fixing surface 41 and the backlight layer 32. In this embodiment, the backlight layer 32 and the fixing plate 40 are connected through the fourth adhesive layer 50, that is, the fourth adhesive layer 50 enables the backlight layer 32 and the display layer 31 to be tightly connected, preventing relative movement or separation between the backlight layer 32 and the display layer 31, thereby improving the structural stability of the entire display panel 30.

[0056] In a further embodiment, the material of the fourth adhesive layer 50 is an epoxy resin material. In this embodiment, the fourth adhesive layer made of epoxy resin material has a strong adhesive force, which can ensure the connection stability between the backlight layer 32 and the fixing plate 40. The fourth adhesive layer made of epoxy resin material also has good chemical corrosion resistance, heat resistance and water resistance, can resist the erosion of various media, and can still maintain stable performance in high-temperature and humid environments, thereby ensuring the installation stability of the display panel 30 and the fixing plate 40.

[0057] As Figure 4 shown, the present utility model also provides a vehicle 200, which includes a center console 210 and the in-vehicle display screen 100 of any one of the above. Regarding the in-vehicle display screen 100, it will not be elaborated here one by one.
