Description

Technical Field

[0001] The embodiments of the present disclosure relate to, but are not limited to, display technology, and in particular to a display device and a vehicle-mounted display system. Background Art

[0002] With the advancement of science and technology, display technology has been constantly evolving. Since the 1990s, society's technological level has rapidly improved, and the market demand for displays has continued to expand. Driven by both technology and demand, liquid crystal display (LCD) technologies have rapidly developed and garnered widespread attention. In 1997, Siemens launched the first color mobile phone, marking the beginning of the development of LCD displays. By 2000, LCD displays were still a luxury accessory for desktop computers. Today, from luxury brands like Mercedes-Benz, BMW, and Audi to new domestic brands, all feature full LCD instrument clusters. LCD instrument clusters are a product of the times and technology, the result of technological innovation, and the fruit of demand. Modern drivers demand not only that their car's instrument cluster display traditional information like speed and fuel level, but also location, navigation, road conditions, and vehicle warnings. Traditional mechanical instruments, standard segment displays, and monochrome thin-film transistor displays (TFT-LCDs) cannot or rarely meet these user requirements, leading to the emergence of full LCD instrument clusters.

[0003] With the rapid development of autonomous driving technology and the significant improvement in people's living standards, people are becoming more concerned with the experience, rather than the driving itself, when owning a car and discussing the driving experience. Today's cars display richer content and information, add more comprehensive and user-friendly features, and create a stronger sense of technology and interactivity. All of this is achieved through the crucial vehicle interface of in-car displays, along with the corresponding screen technology and design. Thanks to the significant reduction in component costs for LCD instrument clusters, digital instrument clusters, once exclusive to high-end brands, have become mainstream in mass production. LCD instrument clusters are widely used in automobiles, and the future of physical instrument clusters is foreseeable. The widespread use of LCD instrument clusters has led to the integration of navigation, control, and instrument clusters (two or three of these) into a single screen, with a coordinated UI design. This allows for all human-computer interactions, including driving information, navigation, and air conditioning, to be controlled on a single screen, creating the ultimate in integrated displays.

[0057] To ensure the same material as the vehicle's interior, the display device's housing is typically made of plastic. The inventors of this disclosure have discovered that some display screens are susceptible to cracking after being secured to the vehicle. This is because the display device relies solely on the plastic housing to secure it to the vehicle, which can easily bend and deform, squeezing the display screen.

[0058] Please combine Figures 1 to 5 and Figures 7 to 11The vehicle-mounted display system provided by an embodiment of the present disclosure will now be described. The vehicle-mounted display system includes a vehicle body 10, a display device 20, and a shielding member 30. The display device 20 includes a housing assembly 21, a metal back plate 22, and a display screen 23. The housing assembly 21 is provided with an installation space 100. The housing assembly 21 has a first side surface 211 and a second side surface 212 disposed opposite to each other. The second side surface 212 is provided with at least one first avoidance space 101 that communicates with the installation space 100. The metal back plate 22 is mounted in the installation space 100. The metal back plate 22 has at least one first connecting member 221. Each first connecting member 221 corresponds to each first avoidance space 101 and can extend from the corresponding first avoidance space 101. The first connecting member 221 is configured to connect to the vehicle body 10. In this way, the entire display device 20 can be mounted on the vehicle body 10 via the first connecting member 221. The display screen 23 is located on the first side surface 211 and is connected to the metal back plate 22. After the display device 20 is installed on the vehicle body 10, the first side surface 211 is located on the viewing side, facilitating viewing of information on the display screen 23. The display screen 23 may be, but is not limited to, a pixelated screen, a monochrome thin-film transistor display, or a liquid crystal display. For ease of description, the display screen 23 is an LCD screen. The display screen 23 is a 10.25-inch screen and includes a glass cover 231 and a liquid crystal module 232. The LCD module 232 comprises a laminated liquid crystal display panel, a backlight source, and a main control board. The display side of the LCD panel is secured with a glass cover 231 to protect the display side of the LCD panel. The main control board can be electrically connected to the backlight source via wiring, or to the power supply unit and other functional components located on the vehicle body 10 via wires. The vehicle body 10 has wire holes for passing wires through. The main control board is secured to the side of the metal backplate 22 facing the display screen 23. The metal backplate 22 is provided with wiring openings for routing wiring for the main control board, including but not limited to power jacks and communication ports. The display device 20 may be installed on the vehicle body 10 at, but is not limited to, a center console or behind a seat.

[0059] In summary, the implementation of the disclosed embodiments will have the following beneficial effects: The display device 20 of the above-described solution, when used in an in-vehicle display system, not only provides the in-vehicle display system with excellent navigation, control, and instrument cluster functions, but also leverages the metallic properties of the metal backplate 22, allowing the metal backplate 22 to directly participate in the structural fixing of the display device 20 to the vehicle body 10. This solves the problem of previously relying solely on a plastic housing assembly 21 for fixing, which is prone to bending, deformation, and squeezing the display screen 23, causing the display screen 23 to crack. Specifically, the display device 20 includes a housing assembly 21 having an installation space 100, a metal backplate 22 mounted in the installation space 100, and a display screen 23. The housing assembly 21 has a first side 211 and a second side 212 disposed opposite each other. The display screen 23 is located on the first side 211 and connected to the metal backplate 22. The metal backplate 22 has at least one first connector 221 that can extend from a first clearance space 101 on the second side 212 to connect to the vehicle body 10. The first connecting member 221 can be integrally formed with the metal back plate 22 by metal casting (including but not limited to metal mold casting, pressure casting, low-pressure casting, centrifugal casting, etc.), so that the first connecting member 221 has the characteristics of greater strength, better rigidity and less deformation, thereby ensuring the precise positioning of the display screen 23 and the vehicle body 10, avoiding relying solely on the outer shell component 21 to fix the display device 20, and reducing the risk of the outer shell component 21 bending, deforming, squeezing and cracking the display screen 23.

[0060] In an exemplary embodiment, please combine Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 、 Figure 8 、 Figure 11 and Figure 12The vehicle body 10 includes an upper surface 11 and a lower surface 12 that are arranged opposite to each other in the vertical direction. The upper surface 11 is provided with a mounting portion 111. The first connecting member 221 is provided on the mounting portion 111. In this way, the mounting position (mounting portion 111) of the first connecting member 221 and the vehicle body 10 is located on the upper surface 11 of the vehicle body 10, which facilitates the connection of the display device 20 to the vehicle body 10 from the upper surface 11, so that the action of locking the display device 20 to the vehicle body 10 is completed on the side of the vehicle body 10 facing the display device 20 and the upper surface 11, and the mounting position where the display device 20 is locked to the vehicle body 10 is visible, making the installation action simple and easy to operate. Compared with the traditional locking of the lower surface 12, it is more operable for mass production, can improve the assembly efficiency of mass-produced vehicles, and reduce manpower and material costs. In the embodiment of the present disclosure, the first connecting member 221 is a plate-like structure, which can increase the connection area between the first connecting member 221 and the mounting portion 111 by fitting with the mounting portion 111, thereby improving the connection stability. The first connector 221 can be fixed to the mounting portion 111 by screws. Both the first connector 221 and the mounting portion 111 have threaded holes, through which screws can be inserted vertically downward to secure the first connector 221 to the mounting portion 111. Before being fixed to the mounting portion 111 by screws, the first connector 221 can be pre-fixed to the mounting portion 111 by plugging, snapping, or other methods.

[0061] The shielding member 30 is provided on the vehicle body 10, and can shield the mounting portion 111 and the first connecting member 221, thereby ensuring the overall appearance of the display device 20 after being installed on the vehicle body 10. The shielding member 30 is detachably connected to the vehicle body 10, and after the first connecting member 221 and the mounting portion 111 are connected, the mounting portion 111 and the first connecting member 221 are shielded. In the embodiment of the present disclosure, the vehicle body 10 has a connecting groove 200 and an assembly groove 300 connected to the connecting groove 200. The mounting portion 111 is located in the assembly groove 300. The outer shell component 21 is located in the connecting groove 200 and matches the portion of the vehicle body 10 circumferentially outside the connecting groove 200, and the shielding member 30 can cooperate with the outer shell component 21 to cover the assembly groove 300, thereby ensuring the overall streamline of the display device 20 after being installed on the vehicle body 10.

[0062] In an exemplary embodiment, please combine Figure 8 、 Figure 10 and Figure 11 The first connecting member 221 includes a first body 2211 and at least one first reinforcing rib 2212. The first reinforcing rib 2212 is arranged on the circumferential outer side of the first body 2211, which can improve the strength of the first body 2211 and reduce the risk of deformation of the first connecting member 221, thereby further ensuring the precise positioning of the display screen 23 and the vehicle body 10, and reducing the risk of the outer shell assembly 21 bending, deforming, squeezing and breaking the display screen 23.

[0063] Both the first body 2211 and the first reinforcing rib 2212 can extend from the corresponding first escape space 101. In the disclosed embodiment, the first escape space 101 matches the first connector 221, so that after extending from the first escape space 101, the first body 2211 and the first reinforcing rib 2212 can form a rotation-stop connection with the housing assembly 21, preventing the first connector 221 from rotating relative to the housing assembly 21 and ensuring the positional accuracy between the first connector 221 and the housing assembly 21. Furthermore, the first connector 221, which has the advantages of high strength, good rigidity, and low deformation, provides support for the housing assembly 21, ensuring the structural stability of the housing assembly 21 and further reducing the risk of the housing assembly 21 bending, deforming, squeezing, and cracking the display screen 23. It can be understood that in other embodiments, the first reinforcing rib 2212 can abut the first inner wall of the housing assembly 21 to form the first escape space 101, similarly utilizing the advantages of the first connector 221, such as high strength, good rigidity, and low deformation, to provide support for the housing assembly 21 and ensure the structural stability of the housing assembly 21.

[0064] In an exemplary embodiment, please combine Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 、 Figure 8 and Figures 10 to 12 The second side surface 212 is further provided with at least one second avoidance space 102 communicating with the installation space 100 .

[0065] The metal backplate 22 also has at least one second connector 222. Each second connector 222 corresponds one-to-one with each second avoidance space 102 and can extend from the corresponding second avoidance space 102. The second connector 222 is provided with a first elastic member 40, and the second connector 222 is elastically connected to the vehicle body 10 via the first elastic member 40. Similarly, the second connector 222 can be integrally formed with the metal backplate 22 through a metal casting method (including but not limited to metal mold casting, pressure casting, low-pressure casting, centrifugal casting, etc.), so that the second connector 222 has the characteristics of high strength, good rigidity, and small deformation, thereby further ensuring the precise positioning of the display screen 23 and the vehicle body 10, avoiding relying solely on the outer shell assembly 21 to fix the display device 20, and reducing the risk of the outer shell assembly 21 bending, deforming, squeezing, and cracking the display screen 23. The first connector 221 and the second connector 222 can be further ensured by setting the number and distribution of the first connector 221 and the second connector 222. Precise positioning of the display screen 23 and the vehicle body 10. In the disclosed embodiment, there are two first connectors 221 and two second connectors 222. The two first connectors 221 are spaced apart perpendicular to the vertical direction and located on either side of a vertically symmetrical plane of the housing assembly 21. The two second connectors 222 correspond one-to-one with the two first connectors 221 and are spaced apart vertically. It is understood that in other embodiments, the number of first connectors 221 and second connectors 222 may vary. The vehicle body 10 is provided with a first plug interface corresponding to the second connectors 222. The two first connectors 221 and the two second connectors 222 are all connected to the vehicle body 10. The first connector 221 is connected to the mounting portion 111. The second connector 222 is inserted into the first plug interface and is engaged with the vehicle body 10 using the elastic force generated by the elastic deformation of the first elastic member 40. The first connector 221 is then secured to the mounting portion 111 using screws. Subsequently, the shielding member 30 is placed over the assembly slot 300 to shield the mounting portion 111 and the first connector 221. In this way, the purpose of quick installation is achieved by opening the assembly groove 300 from the upper surface 11 of the vehicle body 10 in combination with the quick connection method of the second connecting member 222 and the first elastic member 40 through the buckle connection, solving the problem of difficulty in tightening screws from the lower surface 12 of the vehicle body 10 and the time-consuming and labor-intensive problem, thereby improving the installation efficiency of the vehicle during vehicle assembly at the vehicle factory.

[0066] In summary, by customizing the metal back plate 22 with the first connecting member 221 and the second connecting member 222, the metal properties of the metal back plate 22 can be effectively utilized, allowing the metal back plate 22 to directly participate in the fixed installation from a structural perspective, thereby solving the problem of relying on a separate plastic shell component 21 for fixation in the past, and the plastic bending and deformation squeezing the display screen 23 to cause cracks.

[0067] In an exemplary embodiment, please combine Figure 8 and Figure 11The second connecting member 222 includes a second body 2221 , and the second body 2221 has a first insertion end 2222 .

[0068] The first elastic member 40 has two opposing first elastic arms 41 that together form a first opening. The first insertion end 2222 is inserted into the first opening, and the first elastic member 40 can be clamped to the first insertion end 2222. Leveraging the clamping force of the first elastic member 40, the first elastic member 40 can be quickly assembled with the second connecting member 222. The first elastic member 40 is located at the first insertion end 2222, allowing it to elastically deform during the initial connection between the second connecting member 222 and the vehicle body 10, ensuring a stable connection between the first elastic member 40 and the second body 2221. During the connection process between the second connecting member 222 and the vehicle body 10, the first elastic member 40 gradually deforms to adapt to the structure of the second body 2221 and the vehicle body 10, and the elastic force generated also changes accordingly, until the second body 2221 is fully installed and elastically engaged with the vehicle body 10 through the first elastic member 40. The first elastic member 40 also has a first connecting arm that connects the two first elastic arms 41. In the embodiment of the present disclosure, the first elastic member 40 is a metal spring.

[0069] In an exemplary embodiment, please combine Figure 8 、 Figure 11 and Figure 12 The second body 2221 has two first guide grooves 400 disposed opposite each other. The two first elastic arms 41 correspond one-to-one with the two first guide grooves 400, and the first elastic arms 41 are partially accommodated in the corresponding first guide grooves 400. The first elastic arms 41 are configured to slide relative to the first guide grooves 400 during their elastic deformation. In this way, the provision of the first guide grooves 400 ensures the stability of the movement and deformation of the first elastic arms 41 relative to the second body 2221, thereby ensuring the stability of the generated elastic force and improving the stability of the connection between the second connecting member 222 and the vehicle body 10. In the disclosed embodiment, the second body 2221 has groove walls disposed opposite each other along a direction perpendicular to the movement direction of the first elastic arms 41 to limit the range of the first guide grooves 400.

[0070] In an exemplary embodiment, please combine Figure 8 and Figure 11 The two first guide grooves 400 can respectively form a first groove bottom 22211 on the second body 2221 . The first groove bottom 22211 has a first hollow portion 800 on a side away from the first insertion end 2222 . The two first guide grooves 400 are connected through the first hollow portion 800 .

[0071] The first elastic arm 41 is wavy and partially contained within the first hollow portion 800. This further increases the structural area of ​​the first elastic arm 41 constrained by the second body 2221, thereby further ensuring the stability of the first elastic arm 41's movement and deformation relative to the second body 2221. Furthermore, the provision of the first hollow portion 800 provides room for the first elastic arm 41 to deform, ensuring that the first elastic member 40 can gradually deform during the connection between the second connector 222 and the vehicle body 10, thereby preventing the second connector 222 from becoming stuck on the vehicle body 10 when not in place.

[0072] The first elastic arm 41 is provided with a first abutting arm 42. One end of the first abutting arm 42 is connected to the side of the first elastic arm 41 near the first insertion end 2222. The first abutting arm 42 abuts the first groove bottom 22211. The provision of the first abutting arm 42 increases the connection area between the first elastic arm 41 and the first groove bottom 22211, thereby improving the stability of the connection. The two first abutting arms 42 abut against the two first groove bottoms 22211 in a one-to-one correspondence, allowing the two first abutting arms 42 to clamp the second body 2221, further improving the connection stability between the first elastic member 40 and the second body 2221, and preventing the first elastic member 40 from falling off the second body 2221 during the elastic deformation of the first elastic arm 41.

[0073] The other end of the first abutting arm 42 is spaced apart from the first elastic arm 41 , so that the first elastic arm 41 has a greater degree of deformation freedom to adapt to the structures of the second body 2221 and the vehicle body 10 .

[0074] In an exemplary embodiment, please combine Figure 8 、 Figure 10 and Figure 11 The second connecting member 222 also includes at least one second reinforcing rib 2223, which is arranged on the circumferential outer side of the second body 2221, and can enhance the strength of the second body 2221 and reduce the risk of deformation of the second connecting member 222, thereby further ensuring the precise positioning of the display screen 23 and the vehicle body 10, and reducing the risk of the outer shell assembly 21 bending, deforming, squeezing and breaking the display screen 23.

[0075] Both the second body 2221 and the second reinforcing rib 2223 can extend from the corresponding second escape space 102. In the disclosed embodiment, the second reinforcing rib 2223 can abut against the second inner wall of the housing assembly 21 to form the second escape space 102. Leveraging the high strength, good rigidity, and minimal deformation of the second connecting member 222, the second reinforcing rib 2223 provides support for the housing assembly 21, ensuring the structural stability of the housing assembly 21 and further reducing the risk of bending, deformation, squeezing, and cracking of the display screen 23 by the housing assembly 21.

[0076] In an exemplary embodiment, please combine Figure 4 、 Figure 8 、 Figure 10 and Figure 12 The second side surface 212 has at least one third connecting member 213 . The third connecting member 213 is provided with a second elastic member 50 , and the third connecting member 213 is elastically connected to the vehicle body 10 through the second elastic member 50 .

[0077] The third connecting member 213 can be integrally formed with the outer shell component 21 made of plastic material, and has the characteristics of good toughness and deformability of the plastic material, which facilitates the rough positioning of the outer shell component 21 and the vehicle body 10, and serves the purpose of auxiliary positioning. In the embodiment of the present disclosure, the number of third connecting members 213 is two. The two third connecting members 213 correspond one to one with the two second connecting members 222, and are arranged at intervals perpendicular to the vertical direction. They can be connected to the vehicle body 10 together with the first connecting member 221 and the second connecting member 222 to improve the connection stability between the display device 20 and the vehicle body 10. It can be understood that in other embodiments, the number of third connecting members 213 can also be other values. A second plug interface corresponding to the third connecting member 213 is provided on the vehicle body 10. The third connecting member 213 is inserted into the second plug interface and is connected to the vehicle body 10 by the elastic force generated by the elastic deformation of the second elastic member 50.

[0078] In an exemplary embodiment, please combine Figure 4 、 Figure 8 、 Figure 10 and Figure 12 The third connecting member 213 includes a third body 2131 , and the third body 2131 has a second insertion end 2132 .

[0079] The second elastic member 50 has two second elastic arms 51 opposite to each other. The two second elastic arms 51 together form a second opening. The second insertion end 2132 is inserted into the second opening. The second elastic member 50 can be clamped at the second insertion end 2132 .

[0080] By utilizing the clamping force of the second elastic member 50 in this way, the second elastic member 50 and the third connecting member 213 can be quickly assembled. The second elastic member 50 is located at the second insertion end 2132, which facilitates the elastic deformation of the second elastic member 50 in the early stage of connection between the third connecting member 213 and the vehicle body 10, ensuring the stability of the connection between the second elastic member 50 and the third body 2131. The second elastic member 50 can gradually deform during the process of connection between the third connecting member 213 and the vehicle body 10 to adapt to the structure of the third body 2131 and the vehicle body 10, and the elastic force generated also changes accordingly until the third body 2131 is installed in place and elastically clamped to the vehicle body 10 through the second elastic member 50. The second elastic member 50 also has a second connecting arm that connects the two second elastic arms 51. In the embodiment of the present disclosure, the second elastic member 50 is a metal spring.

[0081] In an exemplary embodiment, please combine Figure 8 and Figure 10 The third body 2131 has two second guide grooves 500 disposed opposite each other. The two second elastic arms 51 correspond one-to-one with the two second guide grooves 500, and the second elastic arms 51 are partially accommodated in the corresponding second guide grooves 500. The second elastic arms 51 are configured to slide relative to the second guide grooves 500 during their elastic deformation. The provision of the second guide grooves 500 ensures the stability of the movement and deformation of the second elastic arms 51 relative to the third body 2131, thereby ensuring the stability of the generated elastic force and improving the stability of the connection between the third connecting member 213 and the vehicle body 10. In the disclosed embodiment, the third body 2131 has groove walls disposed perpendicular to the direction of movement of the second elastic arms 51 to limit the range of the second guide grooves 500.

[0082] In an exemplary embodiment, please combine Figure 8 and Figure 10 The two second guide grooves 500 can respectively form a second groove bottom 21311 on the third body 2131 , and the second groove bottom 21311 has a second hollow portion 900 on a side away from the second insertion end 2132 , and the two second guide grooves 500 are connected through the second hollow portion 900 .

[0083] The second elastic arm 51 is wavy and partially contained within the second hollow portion 900. This further increases the structural area of ​​the second elastic arm 51 constrained by the third body 2131, thereby further ensuring the stability of the second elastic arm 51's movement and deformation relative to the third body 2131. Furthermore, the provision of the second hollow portion 900 provides room for the second elastic arm 51 to deform, ensuring that the second elastic member 50 can gradually deform during connection between the third connector 213 and the vehicle body 10, thereby preventing the third connector 213 from becoming stuck on the vehicle body 10 when not in place.

[0084] The second elastic arm 51 is provided with a second abutting arm 52. One end of the second abutting arm 52 is connected to the side of the second elastic arm 51 near the second insertion end 2132. The second abutting arm 52 abuts the second groove bottom 21311. The provision of the second abutting arm 52 increases the connection area between the second elastic arm 51 and the second groove bottom 21311, thereby improving the stability of the connection. The two second abutting arms 52 abut against the two second groove bottoms 21311 in a one-to-one correspondence, allowing the two second abutting arms 52 to clamp the third body 2131, further improving the connection stability between the second elastic member 50 and the third body 2131, and preventing the second elastic member 50 from falling off the third body 2131 during the elastic deformation of the second elastic arm 51.

[0085] The other end of the second abutting arm 52 is spaced apart from the second elastic arm 51 , so that the second elastic arm 51 has a greater degree of deformation freedom to adapt to the structures of the third body 2131 and the vehicle body 10 .

[0086] In an exemplary embodiment, please combine Figure 8 and Figure 10 The third connecting member 213 also includes at least one third reinforcing rib 2133, which is arranged on the circumferential outer side of the third body 2131, and can enhance the strength of the third body 2131 and reduce the risk of deformation of the third connecting member 213, thereby further ensuring the precise positioning of the display screen 23 and the vehicle body 10, and reducing the risk of the outer shell assembly 21 bending, deforming, squeezing and breaking the display screen 23.

[0087] In an exemplary embodiment, please combine Figure 4 、 Figure 8 and Figure 12 The direction of the elastic force exerted by the first elastic member 40 on the vehicle body 10 intersects with the direction of the elastic force exerted by the second elastic member 50 on the vehicle body 10. This allows the directions of the reaction forces exerted on the metal back plate 22 by the vehicle body 10 to intersect. When the external force exerted on the display device 20 is in the same direction as one of the reaction forces, the other reaction force can still ensure the stability of the connection between the display device 20 and the vehicle body 10. In the disclosed embodiment, the direction of the elastic force exerted by the first elastic member 40 on the vehicle body 10 intersects perpendicularly with the direction of the elastic force exerted by the second elastic member 50 on the vehicle body 10.

[0088] In an exemplary embodiment, please combine Figure 3 、 Figure 5 and Figure 9 , the first side surface 211 has a mounting groove 600, the outer shell assembly 21 is provided with a connecting wall 214, the connecting wall 214 is accommodated in the mounting groove 600, and the side of the display screen 23 facing the second side surface 212 is provided on the connecting wall 214. In this way, the connection position between the display screen 23 and the outer shell assembly 21 is located at the connecting wall 214 inside the outer shell assembly 21, which can greatly compress the width of the border of the outer shell assembly 21 surrounding the display screen 23, so that the outer side of the display screen 23 has an ultra-narrow border structure. In the embodiment of the present disclosure, the display screen 23 includes a glass cover plate 231 and a liquid crystal module 232. An external pasting structure is adopted, and the pasting area 700 of the glass cover plate 231 is left on the inner side of the glass cover plate 231 and bonded to the connecting wall 214. The connecting wall 214 is annular, and its outer edge is connected to the outer shell assembly 21.

[0089] The housing assembly 21 also has a circumferential wall 215 located between the first side 211 and the second side 212. The side of the circumferential wall 215 close to the first side 211 is bent toward the display screen 23 and connected to the first side 211. In this way, the side of the circumferential wall 215 close to the first side 211 can form a bevel transition, making the frame narrow and thin. The minimum frame width can be about 2 mm. Among them, the frame width refers to the distance between the circumferential outer side of the display screen 23 and the circumferential outer side of the first side 211. The minimum frame thickness can be about 12 mm. Among them, the frame thickness refers to the vertical distance between the first side 211 and the second side 212.

[0090] After the glass cover 231 is bonded to the connecting wall 214 , the side of the glass cover 231 facing away from the connecting wall 214 is flush with the first side surface 211 , making the display device 20 more beautiful in appearance. The ultra-thin structure fits tightly and perfectly with the vehicle body 10 , forming a seamless whole.

[0091] like Figure 6 As shown, it is a schematic diagram of the installation of a conventional vehicle-mounted display screen 23. Figure 6 As can be seen from the figure, conventional methods of mounting the vehicle display 23 result in a wider frame, adding a length m of the adhesive area 700, which in turn thickens the entire device and increases the thickness h of the adhesive area 700. Furthermore, this adhesive method also creates a step n between the housing assembly 21 and the glass cover 231, affecting the aesthetics. In the disclosed embodiment, an external adhesive structure is employed to optimize both the length m and step n of the adhesive area 700, overlapping the thickness h of the adhesive area 700 with the thickness of the housing assembly 21 itself. This allows the display 23 to be mounted on the housing assembly 21 without increasing the overall thickness.

[0092] In an exemplary embodiment, please combine Figures 3 to 5 , Figures 7 to 10 and Figure 12 The housing assembly 21 includes a front housing 216 and a rear housing 217. The front housing 216 and the rear housing 217 partially overlap, increasing the connection area between the front housing 216 and the rear housing 217, thereby improving the connection stability between the front housing 216 and the rear housing 217. The overlapping area surrounds the display 23, which can improve the sealing performance of the housing assembly 21 to the display 23, preventing moisture, dust, etc. from entering the housing assembly 21 and affecting the normal operation of the display.

[0093] The front housing 216 and the rear housing 217 together form an installation space 100, with the first side 211 located on the front housing 216 and the second side 212 located on the rear housing 217. The display device 20 further includes fasteners 24 connected between the rear housing 217 and the metal backplate 22, capable of abutting the display screen 23 against the connecting wall 214. The fasteners 24 are multiple and evenly distributed, capable of connecting the rear housing 217 to the metal backplate 22. Since the display screen 23 is connected to the metal backplate 22, as the fasteners 24 are tightened, the display screen 23 can drive the connecting wall 214, thereby driving the front housing 216 toward the rear housing 217. Through this tightening process, the display screen 23 and the rear housing 217 can clamp the front housing 216, forming a sandwich structure. This further enhances the connection between the front housing 216 and the rear housing 217, effectively resolving the problem of gaps between the front housing 216 and the rear housing 217 during assembly.

[0094] In summary, the connection method between the display screen 23 and the housing assembly 21 and the sandwich structure formed can maximize space utilization, achieve an ultra-narrow frame and ultra-thin appearance, and reduce the gap between the front shell 216 and the rear shell 217.
