DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0024] like Figures 1 to 7 As shown, the embedded instrument panel display described in this embodiment includes a display assembly 10 and a PCB control board 20. The back of the display assembly 10 is integrated with a communication interface 11, and also includes a light shield 30, a shell 40 and a positioning plate 50. The front of the shell 40 is provided with a stepped first sinking groove 41 and a second sinking groove 42. The bottom of the first sinking groove 41 is provided with a first pillar 411 fixedly connected to the display assembly 10. The circumferential edge of the display assembly 10 is separated from the inner wall of the first sinking groove 41 by a gap; the bottom of the second sinking groove 42 is provided with a first pillar 411 fixedly connected to the PCB control board 20. The second pillar 421 is provided, and a gap is formed between the circumferential edge of the PCB control board 20 and the inner wall of the second sink groove 42; the circumferential surface of the shell 40 extends outward to form a positioning edge 43, and the light shield 30 is buckled with the positioning edge 43 by a buckle 31 and is located on the front of the shell 40; a square hole 51 and a plurality of screw holes 52 are provided on the surface of the positioning plate 50, and the part of the shell 40 corresponding to the second sink groove 42 is placed in the square hole 51, and the positioning plate 50 is fixedly connected to the positioning plate 50 by a stud 53; the bottom of the second sink groove 42 is provided with a threading hole 422.

[0025] Specifically, the embedded instrument panel display described in this embodiment is mainly used on the instrument panels of various vehicles to display vehicle information, navigation information, entertainment information, etc. It includes a display screen assembly 10 and a PCB control board 20; the back of the display screen assembly 10 is integrated with a communication interface 11 for data interaction with other systems of the vehicle, such as receiving speed, fuel level and other information from vehicle sensors, or receiving navigation instructions from the navigation system.

[0026] The outer shell 40 provides support and protection for the entire display screen. A stepped first groove 41 and a second groove 42 are provided on the front thereof, which are used to accommodate the display screen assembly 10 and the PCB control board 20, respectively. A first pillar 411 is provided at the bottom of the first groove 41 for fixing the display screen assembly 10, and a gap is left between the circumferential edge of the display screen assembly 10 and the inner wall of the first groove 41. This design can effectively absorb vibrations during vehicle driving and prevent the display screen assembly 10 from hitting the outer shell 40 and being damaged. Similarly, a second pillar 421 is also provided at the bottom of the second groove 42 for fixing the PCB control board 20, and a gap is also left between its circumferential edge and the inner wall of the second groove 42, which plays the same anti-seismic role. In addition, a threading hole 422 is also provided at the bottom of the second groove 42 to facilitate wiring and line management of the PCB control board 20.

[0027] In addition, the circumferential surface of the shell 40 extends outward to form a positioning edge 43, and the sunshade 30 is buckled with the positioning edge 43 by a buckle 31 and is located on the front of the shell 40 to block direct sunlight and improve the visibility of the display screen. A square hole 51 and several screw holes 52 are provided on the surface of the positioning plate 50. The portion of the corresponding second groove 42 on the shell 40 is placed in the square hole 51, and the positioning plate 50 is fixedly connected to the shell 40 by a stud 53, and the entire display screen assembly is fixed to the dashboard. This design allows the display screen to be firmly mounted on the dashboard, while facilitating installation and disassembly.

[0028] In some embodiments, as Figure 1 、 Figure 7 As shown, a sealing sheet 60 is provided around the opening edge of the first sinking groove 41 . The sealing sheet 60 extends into the first sinking groove 41 and is at least partially in sealing contact with the edge of the front side of the display screen assembly 10 .

[0029] In practice, the sealing sheet 60 is made of a flexible material, such as rubber or silicone, that exhibits excellent elasticity and deformability. Due to its flexibility, the sealing sheet 60 is able to fully contact the front edge of the display assembly 10. Even if the edge of the display assembly 10 has slight irregularities, the sealing sheet 60 can adapt well and maintain a tight fit. The sealing sheet 60 effectively prevents dust from entering the gap between the display assembly 10 and the housing 40. Furthermore, due to its certain elasticity, the sealing sheet 60 also acts as a buffer, absorbing vibrations generated during vehicle operation and further protecting the display assembly 10 from damage due to vibrations.

[0030] In some embodiments, as Figure 2 、 Figure 4 As shown, the positioning edge 43 is provided with a plurality of eyelets 431, through which the buckle 31 is fastened to the positioning edge 43, thereby securing the light shield 30 to the sealing sheet 60. During installation, the buckle 31 on the light shield 30 is simply snapped into the eyelets 431 on the positioning edge 43. This snap-on connection is simple, reliable, and convenient for installation and removal.

[0031] In some embodiments, as Figure 7 As shown, the thickness of the sealing sheet 60 decreases unidirectionally toward the center of the first recessed groove 41. In this embodiment, the thickness of the sealing sheet 60 is designed to gradually decrease from the outside to the inside, that is, the outer edge of the sealing sheet 60 is thickest and gradually becomes thinner toward the center of the first recessed groove 41. This wedge-shaped structure makes the sealing sheet 60 more aesthetically pleasing and makes it easier to deform during installation, allowing it to better conform to the edge of the display assembly 10. Even if the edge of the display assembly 10 has a certain curvature or irregular shape, the sealing sheet 60 can still fit tightly to form a seamless connection, effectively preventing the intrusion of dust and moisture.

[0032] In some embodiments, as Figure 1 、 Figure 3As shown, the PCB control board 20 is integrated with a photosensitive plate (not shown) for controlling the display brightness of the display assembly 10. A light guide cap 21 is fixedly mounted on the front of the housing 40 and is arranged opposite to the photosensitive plate. A clearance notch 32 is provided on the light shield 30 to expose the light guide cap 21. In this embodiment, the photosensitive plate can sense the intensity of the ambient light. In order to enable the photosensitive plate to accurately sense the ambient light, a light guide cap 21 is fixedly mounted on the front of the housing 40 and is arranged opposite to the photosensitive plate. The light guide cap 21 can guide external light to the photosensitive plate to avoid being blocked by other components. At the same time, in order to prevent the light shield 30 from blocking the light from entering the light guide cap 21, a clearance notch 32 corresponding to the light guide cap 21 is provided on the light shield 30 to ensure that external light can smoothly enter the light guide cap 21 and ultimately reach the photosensitive plate. The PCB control board 20 automatically adjusts the display brightness of the display screen assembly 10 according to the light intensity sensed by the photosensitive plate. That is, when the ambient light is strong, the brightness of the display screen assembly 10 is automatically increased; when the ambient light is weak, the brightness of the display screen assembly 10 is automatically reduced.

[0033] In some embodiments, as Figure 2 As shown, heat dissipation grilles 412 communicating with the outside are formed on the inner wall of the second sink 42. These heat dissipation grilles 412 are distributed on the inner wall of the first sink 41, forming multiple heat dissipation channels communicating with the outside. Heat generated by the display assembly 10 during operation can be dissipated to the outside of the housing 40 through these heat dissipation channels, thereby reducing the temperature of the display assembly 10. Air outside the housing 40 can also flow through the heat dissipation grilles 412, removing heat and further improving the heat dissipation effect.

[0034] In some embodiments, as Figure 2 、 Figure 4 As shown, the stud 53 and the positioning plate 50 are integrally injection molded, and the stud 53 is fixedly connected to the positioning edge 43 by a screw, and the positioning edge 43 is provided with a U-shaped bend 432 for accommodating the head of the screw that fixes the stud 53. In this embodiment, the stud 53 and the positioning plate 50 are manufactured by integral injection molding. This means that the stud 53 is no longer a separate part, but is directly molded during the injection molding process of the positioning plate 50, thereby reducing one part and one assembly process. In addition, in order to fix the positioning plate 50 on the housing 40, the stud 53 is connected to the positioning edge 43 of the housing 40 by a screw, and the U-shaped bend 432 on the positioning edge 43 can completely wrap the head of the screw to prevent the head from protruding, which is both beautiful and safe.

[0035] In some embodiments, as Figure 4As shown, two opposing limiting protrusions 433 are provided on the back of the U-shaped bend 432. The distance between the two limiting protrusions 433 matches the diameter of the stud 53. When the positioning plate 50 is fixed by the stud 53 and the positioning edge 43 of the housing 40, the limiting protrusions 433 will be stuck on both sides of the stud 53, effectively limiting the rotation and displacement of the stud 53. Even if external forces are applied during vehicle operation, the stud 53 can remain stable and will not loosen or fall off.

[0036] In some embodiments, as Figure 4 、 Figure 5 As shown, the back of the light shield 30 is integrally formed with a positioning protrusion 33, which is adapted to the circumferential contour of the housing 40. When installing the light shield 30, simply align the positioning protrusion 33 of the light shield 30 with the corresponding position of the housing 40, so that the light shield 30 can be quickly and accurately positioned during installation, avoiding installation misalignment.

[0037] The embedded instrument panel display provided in this embodiment is partially embedded in the square hole of a positioning plate, which is then fixed to the instrument panel. This embedded installation method not only achieves a perfect integration of the display and the instrument panel, improving the overall aesthetics and neatness, but also simplifies the installation process and reduces installation costs. Furthermore, the display assembly and PCB control board are connected to the housing via struts, maintaining a certain gap. This suspended design acts as a shock absorber for the display, effectively preventing damage to the display from vehicle vibrations and improving its stability and service life.
