A high screen-to-body ratio floating in-vehicle display structure

Abstract

This invention provides a high screen-to-body ratio floating vehicle display structure, including a liquid crystal module, a backlight module, a backlight housing, a circuit board, and a connecting shell. The backlight module is integrated within the backlight housing, and the liquid crystal module is fixed to the front end of the backlight housing and encapsulated within it. The connecting shell is fixed to the rear end of the backlight housing, and the circuit board is disposed within the inner cavity of the connecting shell, perpendicular to the liquid crystal module. The connecting shell is embedded and installed on the vehicle dashboard. This solution directly uses the backlight housing as an exterior paint part, integrating the backlight module within it, eliminating the need for the existing overall display shell used as an exterior paint part, thus reducing the black border size of the liquid crystal module. Arranging the circuit board perpendicular to the screen reduces the display's thickness. Fixing the connecting shell, which fits and matches the dashboard, to the backlight housing conceals the internal structures such as the circuit board, achieving the effect of the screen floating on the dashboard.

Description

Technical Field

[0001] This utility model relates to the field of vehicle display technology, specifically to a floating vehicle display structure with a high screen-to-body ratio. Background Technology

[0002] With the development of automotive cockpits, smart cockpits are gradually transforming into a third space for users' lives. In smart cockpits, displays are an indispensable part, becoming the product that users pay the most attention to. This has led to higher requirements from users for in-vehicle displays, driving car manufacturers to provide more trendy and popular display design solutions.

[0003] Currently, in the field of LTPS (Low Temperature Polycrystalline Silicon) displays, automotive displays have relatively large bezels and thicknesses due to the need to fix components such as glass covers and backlights. With the trend of smart cockpit technology development, narrow bezels and thin screens will be the mainstream design solutions for displays to meet the development trend of smart cockpits. Utility Model Content

[0004] To address the aforementioned technical issues, this invention provides a high screen-to-body ratio floating in-vehicle display structure that reduces the size of the black border and the thickness of the screen. The narrow black border screen enhances the user experience by maximizing the display area for the user interface; the thinner floating display also improves the overall technological feel of the cabin.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A high screen-to-body ratio floating vehicle display structure is provided, comprising: a liquid crystal module, a backlight module, a backlight back cover, a circuit board, and a connecting shell; the backlight back cover directly serves as the outer shell of the display, the backlight module is integrated within the backlight back cover, the liquid crystal module is fixed to the front end of the backlight back cover and encapsulated within the backlight back cover; the connecting shell is fixed to the rear end of the backlight back cover, the circuit board is disposed in the inner cavity of the connecting shell and is perpendicular to the liquid crystal module, and the connecting shell is embedded in and mounted on the vehicle dashboard.

[0007] Furthermore, the backlight housing has a T-shaped structure, consisting of a backlight housing portion and a circuit board support portion connected vertically. The backlight module is installed inside the backlight housing portion, and the circuit board is fixed on the circuit board support portion, which is hidden in the inner cavity of the connecting housing.

[0008] Furthermore, the backlight housing serves as an exterior paint part.

[0009] Furthermore, assembly sliders are installed on both sides of the connecting shell, and a connecting shell mounting part matching the connecting shell is provided on the vehicle dashboard. The connecting shell mounting part is provided with a slide rail that cooperates with the assembly slider.

[0010] Furthermore, the floating vehicle display structure also includes metal clips, which are fixed to the rear end of the circuit board bracket for pre-fixation to the vehicle dashboard.

[0011] Furthermore, the liquid crystal module is fixedly connected to the front peripheral flange of the backlight back cover by adhesive.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention relates to a floating vehicle-mounted display screen structure. The backlight housing is directly used as an exterior paint component, integrating the backlight module within it. This eliminates the need for the existing overall display screen shell, which is also an exterior paint component, thus reducing the screen's black border size. The backlight housing is designed in a T-shape, with the circuit board arranged perpendicularly to the screen within this T-shape. This alters the circuit board layout, further reducing the screen's thickness. A connecting shell, which fits snugly against the dashboard, is fixed to the backlight housing, concealing the circuit board and other internal structures, achieving the effect of the screen floating above the dashboard. Attached Figure Description

[0014] To more clearly illustrate the specific embodiments of this utility model or the technical solutions in the prior art, the drawings used in the description of the specific embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0015] Figure 1 An exploded structural diagram of the floating vehicle display screen structure of this utility model is shown;

[0016] Figure 2 A schematic diagram of the assembly structure of the floating vehicle display screen of this utility model is shown. Detailed Implementation

[0017] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0018] like Figure 1 , Figure 2As shown, in this embodiment, the floating vehicle display structure includes a liquid crystal module 1, a backlight module 2, and a backlight back cover 3. A cavity is formed at the front end of the backlight back cover 3, and the backlight module 2 is integrated into the cavity. The cavity is surrounded by flanges, and the liquid crystal module 1 is fixed to the front flange of the backlight back cover 3, thereby encapsulating the backlight module 2 within the backlight back cover 3. The liquid crystal module 2 is fixed to the backlight back cover 3 with adhesive.

[0019] As those skilled in the art will understand, in existing automotive displays, the backlight housing is located inside the display housing, resulting in a large outer perimeter of the display housing. Given the size limitations of the backlight module, the screen display area is fixed, requiring a wider black border to ensure the liquid crystal components fit snugly against the perimeter of the display housing. This embodiment directly uses the backlight housing 3 as the display housing, essentially treating it as an exterior paint part. The backlight module 2 is integrated into the backlight housing 3, reducing the need for additional parts for exterior paint, thereby reducing the size of the black border (i.e., the portion from the display area to the edge of the glass cover), allowing the displayed image to occupy as much of the display screen as possible.

[0020] In summary, integrating the exterior components and the backlight housing into a single backlight housing reduces one bonding process and one bonding surface, thus reducing the black border size to 5mm, while the industry standard is currently more than 8mm.

[0021] The floating vehicle display structure also includes a circuit board 5 and a connecting shell 6. The backlight back shell 3 has a T-shaped structure, consisting of a vertically connected backlight shell portion 31 and a circuit board support portion 32. The backlight module 2 is installed inside the backlight shell portion 31, and the circuit board 5 is fixed to the circuit board support portion 32 with screws. The connecting shell 6 is fixed to the rear end of the backlight back shell 3, and the circuit board support portion 32 is hidden in the inner cavity of the connecting shell 6, that is, the circuit board 5 is set in the inner cavity of the connecting shell 6. The circuit board 5 is set perpendicular to the liquid crystal module 1, and the plastic connecting shell 6 is embedded in and installed on the vehicle dashboard.

[0022] As those skilled in the art will understand, in the prior art, the circuit board is set parallel to the LCD screen, which results in a large overall display thickness. The solution of this utility model places the circuit board perpendicular to the screen, greatly reducing the screen thickness to as low as 9mm, compared to the industry standard of over 13mm. In conjunction with this, the circuit board support portion 32 and the circuit board 5 are hidden within the connecting shell 6, which is embedded in the vehicle's dashboard. This not only reduces the screen thickness but also creates the effect of the screen floating above the dashboard, enhancing the overall technological feel of the vehicle's cabin.

[0023] In a preferred embodiment, mounting sliders 4 are installed on both sides of the connecting shell 6. A connecting shell mounting part (U-shaped structure) matching the connecting shell 6 is provided on the vehicle dashboard, and a slide rail that cooperates with the mounting sliders is provided inside the connecting shell mounting part. A metal clip 7 is fixed to the rear end of the circuit board bracket part 32. The assembly process is as follows: After the LCD module 1, backlight module 2, backlight back shell 3, mounting sliders 4, circuit board 5 and connecting shell 6 are assembled (the circuit board bracket part 32 passes through the connecting shell 6, and the metal clip 7 is exposed from the rear opening of the connecting shell 6), the display screen structure is pushed into the connecting shell mounting part on the vehicle dashboard by the cooperation of the mounting sliders 4 and the slide rails. When pushed into place, the metal clip 7 is pre-fixed to the vehicle dashboard (the connecting shell mounting part is provided with a fixing part that engages with the metal clip 7). Then, the connecting shell 6 is fastened to the vehicle dashboard by screws, so as to achieve the effect of the display screen floating on the dashboard.

[0024] The above are merely preferred embodiments of this utility model and are illustrative rather than restrictive. The structure and connection methods of the components in this utility model can be varied. Any equivalent transformations and improvements made based on the technical solution of this utility model should not be excluded from the protection scope of this utility model.
