[0031] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figure 1 and Figure 2 As shown, the vehicle-mounted display 100 of this embodiment includes a cover plate 1, a backlight housing 2, a display screen 3, and a circuit board 4. The backlight housing 2 includes a plate 21 and an annular frame 22. The frame 22 is located on the side of the plate 21 facing the cover plate 1 and is connected to the cover plate 1. The cover plate 1 and the backlight housing 2 form a mounting cavity 23. The display screen 3 is located in the mounting cavity 23, and the circuit board 4 is located on the side of the plate 21 facing away from the cover plate 1. The plate 21 has a wire through hole 211, and the circuit board 4 is electrically connected to the display screen 3 through a signal line 5 passing through the wire through hole 211. The cover plate 1 can be a glass plate; the display screen 3 can be an LCD display screen.

[0033] The vehicle-mounted display 100 of this embodiment of the utility model has a frame 22 disposed on the side of the plate 21 facing the cover plate 1 and connected to the cover plate 1, so that the cover plate 1 and the backlight housing 2 form a mounting cavity 23. The display screen 3 is disposed in the mounting cavity 23, and the circuit board 4 is disposed on the side of the plate 21 facing away from the cover plate 1. A wire through hole 211 is provided on the plate 21, so that the circuit board 4 is electrically connected to the display screen 3 through the signal line 5 passing through the wire through hole 211, thereby realizing the power supply to the display screen 3. Since the plate 21 is hidden inside the vehicle when the vehicle-mounted display 100 is connected to the vehicle, the signal line 5 is not exposed to the outside, so it does not affect the appearance of the vehicle-mounted display 100. This eliminates the need for a cover to shield the signal line 5, reducing the cost of the vehicle-mounted display 100.

[0034] To make the technical solution of this utility model easier to understand, the following description uses the example of the thickness direction of the vehicle display 100 being consistent with the front-to-back direction to further illustrate the technical solution of this utility model. Wherein, the front-to-back direction is as follows... Figure 1 and Figure 2 As shown.

[0035] For example, such as Figure 1 and Figure 2 As shown, the frame 22 is located on the front side of the board 21, and the cover plate 1 is located on the front side of the frame 22. The rear surface of the cover plate 1, the inner surface of the frame 22, and the front surface of the board 21 form a mounting cavity 23. The display screen 3 is located on the front side of the board 21, and the circuit board 4 is located on the rear side of the board 21. The through hole 211 extends in the front-back direction, and the signal line passes through the through hole 211 in the front-back direction. The front end of the signal line 5 is connected to the display screen 3, and the rear end of the signal line 5 is connected to the circuit board 4.

[0036] In some embodiments, the outer side of the frame 22 is provided with a decorative coating. "Inward" can be understood as a direction close to the center line of the vehicle display 100 on a plane perpendicular to the thickness direction of the vehicle display 100, and "outward" can be understood as a direction away from the center line of the vehicle display 100 on a plane perpendicular to the thickness direction of the vehicle display 100. The inner side of the frame 22 is closer to the center line of the vehicle display 100 than the outer side of the frame 22.

[0037] When the in-vehicle display 100 is connected to the vehicle, the bezel 22 is exposed, affecting the appearance of the in-vehicle display 100. By applying a decorative coating to the outer side of the bezel 22, the appearance quality of the in-vehicle display 100 can be improved, thus enhancing the user experience.

[0038] In some embodiments, such as Figure 1 and Figure 2As shown, the vehicle display 100 also includes a backlight 7, which is located in the mounting cavity 23 and between the display screen 3 and the panel 21. The signal line 5 is located on the outer edge of the backlight 7.

[0039] For example, such as Figure 1 and Figure 2 As shown, the backlight 7 is located on the rear side of the display screen 3 and on the front side of the board 21. The signal line 5 is located on the lower side of the backlight 7.

[0040] By placing the signal line 5 on the outer edge of the backlight component 7, interference between the signal line 5 and the backlight component 7 can be avoided, facilitating the electrical connection between the signal line 5 and the display screen 3 and the circuit board 4.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the backlight housing 2 is integrally disposed on the side of the cover plate 1 facing the display screen 3 in the thickness direction of the vehicle display 100.

[0042] For example, such as Figure 1 and Figure 2 As shown, the display screen 3 is located on the rear side of the cover plate 1, so the side of the cover plate 1 facing the display screen 3 is the rear side. The backlight housing 2 is located entirely on the rear side of the cover plate 1 in the front-back direction, and the front end of the frame 22 is connected to the rear surface of the cover plate 1.

[0043] By placing the backlight housing 2 entirely on the side of the cover plate 1 facing the display screen 3 in the thickness direction of the vehicle display 100, not only can the overall size of the backlight housing 2 be reduced and the weight of the vehicle display 100 be reduced, but the backlight housing 2 can also be completely hidden on the side of the cover plate 1 facing the display screen 3, so that the frame 22 is not visible on the side of the cover plate 1 facing away from the cover plate 1, giving the display screen 3 a floating screen effect.

[0044] In some embodiments, such as Figure 1 and Figure 2 As shown, the wire hole 211 and the circuit board 4 are both offset towards the same side of the board 21 in the height direction of the vehicle display 100, or the wire hole 211 and the circuit board 4 are both offset towards the same side of the board 21 in the width direction of the vehicle display 100.

[0045] By setting the wire hole 211 and the circuit board 4 to the same side of the board 21 in the height direction of the vehicle display 100, or setting the wire hole 211 and the circuit board 4 to the same side of the board 21 in the width direction of the vehicle display 100, the distance between the wire hole 211 and the circuit board 4 is made closer, so that the connection between the signal line 5 and the circuit board 4 can be achieved with a shorter signal line 5, further reducing the cost of the vehicle display 100.

[0046] To make the technical solution of this utility model easier to understand, the following example illustrates the technical solution of this utility model by assuming that the height direction of the vehicle display 100 is consistent with the vertical direction, and the width direction of the vehicle display 100 is consistent with the horizontal direction. Specifically, the vertical direction is as follows... Figures 1 to 3 As shown, the left and right directions are as follows Figure 3 As shown.

[0047] For example, such as Figure 1 and Figure 2 As shown, the wire hole 211 and the circuit board 4 are both offset towards the lower side of the board body 21 in the vertical direction. The wire hole 211 and the circuit board 4 can also be offset towards the left side of the board body 21 in the horizontal direction.

[0048] Optionally, the wire hole 211 and the circuit board 4 are both offset towards the bottom of the board body 21 in the height direction of the vehicle display 100.

[0049] For example, such as Figure 1 and Figure 2 As shown, the wire hole 211 and the circuit board 4 are both offset towards the lower side of the board body 21 in the vertical direction, and correspondingly, the signal line 5 is also offset towards the lower side of the board body 21.

[0050] By setting the wire hole 211 and the circuit board 4 both towards the bottom of the board 21 in the height direction of the vehicle display 100, the signal line 5 and the circuit board 4, which have a certain weight, are both set towards the bottom of the board 21. This helps to lower the center of gravity of the vehicle display 100 and improve the stability of the vehicle display 100 when it is placed.

[0051] In some embodiments, the signal line 5 is sheet-like, and the through hole 211 is an elongated hole extending along the width direction of the signal line 5.

[0052] For example, signal line 5 is a flexible printed circuit board (FPC).

[0053] By making the signal line 5 into a sheet shape, the signal line 5 can transmit high-speed video signals, improving the performance of the vehicle display 100. By making the cable pass-through hole 211 into an elongated hole extending along the width direction of the signal line 5, the opening area of ​​the cable pass-through hole 211 is small while allowing the signal line 5 to pass through, which helps to improve the reliability of the board 21, thereby improving the reliability of the vehicle display 100.

[0054] Optionally, such as Figure 3 As shown, the frame 22 includes a first frame 221 and a second frame 222, with the extension direction of the first frame 221 intersecting the extension direction of the second frame 222. The width direction of the signal line 5 is consistent with the extension direction of the first frame 221, and the through hole 211 is disposed between the first frame 221 and the display screen 3 in the extension direction of the second frame 222.

[0055] For example, the width of signal line 5 is in the left-right direction. Figure 3 As shown, the first frame 221 extends in the left-right direction, and the second frame 222 extends in the up-down direction. The cable guide hole 211 is located on the lower side of the display screen 3 and on the upper side of the first frame 221. This makes the size of the cable guide hole 211 smaller in the up-down direction, allowing the size of the display screen 3 to be larger in the up-down direction, and the size of the display screen 3 in the left-right direction is not affected by the cable guide hole 211.

[0056] Therefore, the above-described design of the first frame 221, the second frame 222, and the wire hole 211 of the frame 22 facilitates the large-screen design of the vehicle display 100.

[0057] Optionally, such as Figure 3 As shown, there are multiple wire holes 211, which are arranged at intervals along the extension direction of the first frame 221.

[0058] For example, such as Figure 3 As shown, there are three wire holes 211, which are arranged at intervals along the left and right directions.

[0059] By setting multiple wire holes 211, multiple signal lines 5 can be set, which better meets the connection requirements between the display screen 3 and the circuit board 4.

[0060] In some embodiments, such as Figure 2 As shown, the vehicle display 100 also includes a protective housing 6, which is located on the side of the plate 21 facing away from the cover plate 1 and connected to the plate 21. The protective housing 6 and the plate 21 form a receiving cavity 61. The portions of the circuit board 4 and the signal lines 5 located outside the mounting cavity 23 are all located inside the receiving cavity 61.

[0061] For example, such as Figure 2 As shown, the protective shell 6 is located on the rear side of the board 21, and the protective shell 6 covers the part of the circuit board 4 and the signal line 5 located outside the mounting cavity 23.

[0062] By setting up a protective shell 6, a cavity 61 is formed between the protective shell 6 and the board 21. The protective shell 6 can be used to protect the circuit board 4 and the signal line 5, thereby improving the reliability of the vehicle display 100.

[0063] Optionally, such as Figure 2 As shown, the orthographic projection of the protective shell 6 in the direction toward the plate 21 is located inside the edge of the plate 21. In other words, the orthographic projection of the protective shell 6 in the direction toward the plate 21 does not exceed the edge of the plate 21.

[0064] For example, the orthographic projection of the protective shell 6 in the forward direction is located inside the edge of the plate 21.

[0065] By setting the orthographic projection of the protective shell 6 in the direction toward the plate 21 to be located inside the edge of the plate 21, on the one hand, the protective shell 6 will not protrude from the frame of the backlight shell 2, which is beneficial to improving the appearance quality of the vehicle display 100; on the other hand, the overall size of the protective shell 6 is smaller, which can further reduce the weight of the vehicle display 100.

[0066] like Figure 1 and Figure 2 As shown, the vehicle display 100 also includes a connector 8, a screen driver chip 9, and a timing control chip 10. The connector 8 is electrically connected to the circuit board 4, the screen driver chip 9 is electrically connected to the display screen 3, and the timing control chip 10 is electrically connected to the circuit board 4.

[0067] The vehicle-mounted display 100 of this embodiment utilizes a special structural design for the backlight housing 2, which simultaneously serves as an external structural component of the vehicle-mounted display 100. This reduces the number and thickness of the components, significantly lowering the thickness and cost of the vehicle-mounted display 100. By placing the cable routing hole 211 within the plate 21 of the backlight housing 2, the cable routing hole 211 can be hidden on the rear side of the backlight housing 2. This not only allows the display screen 3 to maintain its floating screen design but also ensures that after the vehicle-mounted display 100 is connected to the vehicle, the circuit board 4 and signal lines 5 are concealed within the vehicle's interior, maintaining overall aesthetic consistency. Consequently, the vehicle-mounted display 100 achieves an ultra-thin, ultra-narrow, and floating screen effect.

[0068] The vehicle of this utility model embodiment includes the in-vehicle display 100 described in any of the above embodiments. The in-vehicle display 100 can be mounted on the vehicle's center console; it can also be mounted between the first and second rows of seats, serving as a second-row screen.

[0069] Because the vehicle display 100 of this utility model embodiment has advantages such as light weight and low cost, the vehicle of this utility model embodiment has advantages such as low cost.

[0070] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions and variations made to the above embodiments by those skilled in the art are within the protection scope of the present invention.
