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 development of science and technology, display technology is also constantly updated. After entering the 1990s, the level of social science and technology has rapidly improved, and the market demand for displays has continued to expand. Driven by technology and demand, liquid crystal display technology has developed rapidly and has attracted widespread attention. In 1997, Siemens launched the first color screen mobile phone in history, and liquid crystal displays have gradually developed. By 2000, LCD monitors were still a relatively luxurious accessory for desktop computers. Today, from Mercedes-Benz, BMW, Audi and other famous brands to domestic new forces, all cars have begun to use full LCD instruments. Liquid crystal instruments are the product of the times and technology, the result of technological innovation, and the fruit of demand. When driving a car, contemporary drivers not only require the car's dashboard to display traditional information such as speed and fuel level, but also require the dashboard to display information such as location, navigation, road conditions and vehicle condition warnings. For these user requirements, traditional mechanical instruments, ordinary segment displays and monochrome thin film transistor displays cannot meet or are difficult to meet, so full LCD instruments came into being.

[0003] With the substantial development of autonomous driving technology and the great improvement of human living standards, people care more about the experience rather than driving when owning a car and discussing the driving experience of a car. Today's cars show people richer content and information, add more comprehensive and more humanized functions, and bring a stronger sense of technology and interaction. All of these are inseparable from the important carrier of the car screen, as well as the corresponding screen technology and styling design. Thanks to the significant reduction in the component cost of LCD instruments, digital instruments that were once exclusive to high-end brands have become mainstream in mass production. LCD instruments are widely used in cars, and it is foreseeable that physical instruments will disappear in the future. The popularization of LCD instruments has made the navigation screen, control screen, combination instrument (two or three of them) and other screens combined into one screen as the main body, and the UI linkage design. This enables all human-computer interactions such as driving information, navigation information, air conditioning information, etc. to be operated on one screen, forming the ultimate way of combining screens.

[0057] In order to ensure that the shell component of the display device is made of the same material as the interior of the vehicle body, the shell component of the display device is generally made of plastic material. The inventor of the present disclosure has found that the display screen of some display devices is easily broken after being fixed to the vehicle body. This is because the display device is fixed to the vehicle body solely by the shell component of plastic material, and the shell component of plastic material is easy to bend and deform, squeezing the display screen.

[0058] Please combine Figures 1 to 5 and Figures 7 to 11, the vehicle-mounted display system provided by the embodiment of the present disclosure is now described. The vehicle-mounted display system includes a vehicle body 10, a display device 20 and a shielding member 30.

The housing assembly 21 has a first side surface 211 and a second side surface 212 arranged opposite to each other. The second side surface 212 is provided with at least one first avoidance space 101 connected to the installation space 100. The metal back plate 22 is installed 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 one by one, and can extend from the corresponding first avoidance space 101, and the first connecting member 221 is arranged to be connected to the vehicle body 10. In this way, the entire display device 20 can be installed on the vehicle body 10 through 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 observation side, which is convenient for observing the information on the display screen 23. The display screen 23 may be, but is not limited to, a broken code screen, a monochrome thin film transistor display screen or a liquid crystal display screen. For the convenience of describing the present disclosure, the display screen 23 is an example of a liquid crystal display screen. The display screen 23 is a 10.25-inch screen, including a glass cover plate 231 and a liquid crystal module 232. Among them, the liquid crystal module 232 includes a laminated liquid crystal display panel, a backlight source and a main control board. The display side cover of the liquid crystal display panel is fixed with a glass cover plate 231 to protect the display side of the liquid crystal display panel. The main control board can be electrically connected to the backlight source by means of wiring, or can be electrically connected to the power supply unit and other functional components arranged on the vehicle body 10 by wires. The vehicle body 10 has a wire hole through which the wire passes. The main control board is fixed to the side of the metal back plate 22 facing the display screen 23. The metal back plate 22 is provided with a wiring opening for facilitating the wiring of the main control board, and the wiring opening includes but is not limited to a power socket and a communication interface. 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 embodiment will have the following beneficial effects: the display device 20 of the above scheme is applied to the vehicle display system. In addition to making the vehicle display system have excellent navigation, control, combination instrument and other functions, it can also use the metal properties of the metal back plate 22 to allow the metal back plate 22 to directly participate in the fixed installation of the display device 20 and the vehicle body 10 from a structural point of view, thereby solving the problem that the previous fixed shell component 21 made of plastic material alone is easy to bend and deform to squeeze the display screen 23, resulting in the cracking of the display screen 23. Specifically, the display device 20 includes a shell component 21 provided with an installation space 100, a metal back plate 22 installed in the installation space 100, and a display screen 23. Among them, the shell component 21 has a first side 211 and a second side 212 arranged opposite to each other. The display screen 23 is located on the first side 211 and connected to the metal back plate 22. The metal back plate 22 has at least one first connecting member 221, which can extend from the first avoidance space 101 located on the second side 212 to connect with 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 , Fig.11 and Fig.12The vehicle body 10 includes an upper surface 11 and a lower surface 12 which 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 arranged 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 with 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 disclosed embodiment, 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 connecting member 221 can be fixed to the mounting portion 111 by screws. The first connecting member 221 and the mounting portion 111 are both provided with threaded holes, and the screws can pass through the threaded holes downward in the vertical direction to lock the first connecting member 221 and the mounting portion 111. Before being fixed to the mounting portion 111 by screws, the first connecting member 221 can be pre-fixed with the mounting portion 111 by plugging, clamping, etc.

[0061] The shielding member 30 is disposed on the vehicle body 10, and can shield the mounting portion 111 and the first connecting member 221, thereby ensuring the overall aesthetic 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 disclosed embodiment, 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 housing assembly 21 is located in the connecting groove 200, and matches the portion of the vehicle body 10 on the circumferential outside of the connecting groove 200, and the shielding member 30 can cooperate with the housing assembly 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 , Fig.10 and Fig.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 rupturing the display screen 23.

[0063] The first body 2211 and the first reinforcing rib 2212 can both extend from the corresponding first avoidance space 101. In the disclosed embodiment, the first avoidance space 101 matches the first connector 221, so that the first body 2211 and the first reinforcing rib 2212 can form a non-rotation connection with the housing assembly 21 after extending from the first avoidance space 101, thereby preventing the first connector 221 from rotating relative to the housing assembly 21, ensuring the position accuracy between the first connector 221 and the housing assembly 21, and then using the characteristics of the first connector 221 such as high strength, good rigidity and small deformation to provide 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 and deforming to squeeze the display screen 23 and break. It can be understood that in other embodiments, the first reinforcing rib 2212 can abut against the first inner wall of the housing assembly 21 to form the first avoidance space 101, and also using the characteristics of the first connector 221 such as high strength, good rigidity and small deformation to provide support for the housing assembly 21, ensuring 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 also provided with at least one second avoidance space 102 communicating with the installation space 100 .

[0065] The metal back plate 22 also has at least one second connecting member 222, each second connecting member 222 corresponds to each second avoidance space 102 one by one, and can extend from the corresponding second avoidance space 102, and the second connecting member 222 is provided with a first elastic member 40, and the second connecting member 222 is elastically connected to the vehicle body 10 through the first elastic member 40. Similarly, the second connecting member 222 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 second connecting member 222 has the characteristics of greater strength, better rigidity and less deformation, thereby further ensuring the accurate positioning of the display screen 23 and the vehicle body 10, avoiding relying solely on the housing component 21 to fix the display device 20, and reducing the risk of the housing component 21 bending and deforming to squeeze the display screen 23 and rupture. The first connecting member 221 and the second connecting member 222 can further ensure the accurate positioning of the display screen 23 and the vehicle body 10 by setting the number and distribution method. In the embodiment of the present disclosure, the number of the first connectors 221 is two, the number of the second connectors 222 is two, the two first connectors 221 are arranged at intervals perpendicular to the vertical direction and are located on both sides of the symmetry plane of the housing assembly 21 along the vertical direction, and the two second connectors 222 correspond to the two first connectors 221 one by one and are arranged at intervals along the vertical direction. It can be understood that in other embodiments, the number of the first connectors 221 and the second connectors 222 can also be other values. A first plug interface corresponding to the second connector 222 is provided on the vehicle body 10. 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 clamped to the vehicle body 10 by the elastic force generated by the elastic deformation of the first elastic member 40, and the first connector 221 is fixed to the mounting portion 111 by screws. Afterwards, the shielding member 30 is covered on the assembly groove 300 to shield the mounting portion 111 and the first connector 221. In this way, the purpose of quick installation is achieved by opening an assembly groove 300 from the upper surface 11 of the vehicle body 10 in combination with a quick connection method of a buckle connection between the second connecting member 222 and the first elastic member 40, thereby solving the problem of being difficult to tighten screws from the lower surface 12 of the vehicle body 10 and wasting time and effort, thereby improving the installation efficiency of the vehicle manufacturer during vehicle assembly.

[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 point of view, 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 Fig.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 first elastic arms 41 arranged opposite to each other, the two first elastic arms 41 enclose a first opening, the first insertion end 2222 is inserted in the first opening, and the first elastic member 40 can be clamped at the first insertion end 2222. In this way, the clamping force of the first elastic member 40 is utilized to facilitate the rapid assembly of the first elastic member 40 and the second connecting member 222. The first elastic member 40 is located at the first insertion end 2222, so that the first elastic member 40 can be elastically deformed at the initial stage of the connection between the second connecting member 222 and the vehicle body 10, thereby ensuring the connection stability between the first elastic member 40 and the second body 2221. The first elastic member 40 can be gradually deformed during the connection between the second connecting member 222 and the vehicle body 10 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 installed in place and elastically clamped to the vehicle body 10 through the first elastic member 40. The first elastic member 40 also has a first connecting arm connecting the two first elastic arms 41. In the disclosed embodiment, the first elastic member 40 is a metal spring.

[0069] In an exemplary embodiment, please combine Figure 8 , Fig.11 and Fig.12 The second body 2221 has two first guide grooves 400 disposed opposite to each other, and the two first elastic arms 41 correspond to the two first guide grooves 400 one by one, and the first elastic arms 41 are partially accommodated in the corresponding first guide grooves 400, and the first elastic arms 41 are configured to be able to slide relative to the first guide grooves 400 during their elastic deformation. In this way, the stability of the movement and deformation of the first elastic arms 41 relative to the second body 2221 can be ensured by the provision of the first guide grooves 400, thereby ensuring the stability of the elastic force generated, and improving the connection stability between the second connecting member 222 and the vehicle body 10. In the disclosed embodiment, the second body 2221 has groove walls that are relatively arranged 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 Fig.11 The two first guide grooves 400 can respectively form a first groove bottom 22211 on the second body 2221 , and the first groove bottom 22211 has a first hollow portion 800 on a side away from the first insertion end 2222 , and 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 in the first hollow portion 800, so that the structural area of ​​the first elastic arm 41 restricted by the second body 2221 can be further increased, thereby further ensuring the stability of the first elastic arm 41 in moving and deforming relative to the second body 2221. In addition, the provision of the first hollow portion 800 can provide a deformation space for the first elastic arm 41, ensuring that the first elastic member 40 can gradually deform during the process of connecting the second connecting member 222 with the vehicle body 10, thereby preventing the second connecting member 222 from being stuck in the vehicle body 10 when it is not moved into 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 a side of the first elastic arm 41 close to the first insertion end 2222, and the first abutting arm 42 abuts against the first groove bottom 22211. In this way, the connection area between the first elastic arm 41 and the first groove bottom 22211 can be increased by the provision of the first abutting arm 42, thereby improving the connection stability. The two first abutting arms 42 abut against the two first groove bottoms 22211 one by one, so that the two first abutting arms 42 can 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 from 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 , Fig.10 and Fig.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 improve 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 rupturing the display screen 23.

[0075] The second body 2221 and the second reinforcing rib 2223 can both extend from the corresponding second avoidance space 102. In the disclosed embodiment, the second reinforcing rib 2223 can abut against the second inner wall of the second avoidance space 102 formed by the outer shell assembly 21, and the second connecting member 222 is used to provide support for the outer shell assembly 21 by utilizing its high strength, good rigidity and small deformation, thereby ensuring the structural stability of the outer shell assembly 21 and further reducing the risk of bending, deformation, squeezing and cracking of the display screen 23 by the outer shell assembly 21.

[0076] In an exemplary embodiment, please combine Figure 4 , Figure 8 , Fig.10 and Fig.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 clamped 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 of plastic material, and has the characteristics of good toughness and deformability of 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 disclosed in the present invention, the number of the third connecting members 213 is two. The two third connecting members 213 correspond to the two second connecting members 222 one by one, 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 the 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 , Fig.10 and Fig.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, 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 the connection between the third connecting member 213 and the vehicle body 10, thereby ensuring the connection stability between the second elastic member 50 and the third body 2131. The second elastic member 50 can gradually deform during the 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 disclosed embodiment, the second elastic member 50 is a metal spring.

[0081] In an exemplary embodiment, please combine Figure 8 and Fig.10 The third body 2131 has two second guide grooves 500 disposed opposite to each other, the two second elastic arms 51 correspond to the two second guide grooves 500 one by one, and the second elastic arms 51 are partially accommodated in the corresponding second guide grooves 500, and the second elastic arms 51 are configured to slide relative to the second guide grooves 500 during their elastic deformation. In this way, the stability of the movement and deformation of the second elastic arms 51 relative to the third body 2131 can be ensured by the provision of the second guide grooves 500, thereby ensuring the stability of the elastic force generated and improving the connection stability between the third connecting member 213 and the vehicle body 10. In the disclosed embodiment, the third body 2131 has groove walls disposed opposite to each other in a direction perpendicular to the movement direction 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 Fig.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 one 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 in the second hollow portion 900, so that the structural area of ​​the second elastic arm 51 restricted by the third body 2131 can be further increased, thereby further ensuring the stability of the second elastic arm 51 in moving and deforming relative to the third body 2131. In addition, the second hollow portion 900 can provide a deformation space for the second elastic arm 51, ensuring that the second elastic member 50 can gradually deform during the process of connecting the third connecting member 213 with the vehicle body 10, thereby preventing the third connecting member 213 from being stuck on the vehicle body 10 when it is not moved into place.

[0084] The second elastic arm 51 is provided with a second abutting arm 52, one end of which is connected to a side of the second elastic arm 51 close to the second insertion end 2132, and the second abutting arm 52 abuts against the second groove bottom 21311. In this way, the connection area between the second elastic arm 51 and the second groove bottom 21311 can be increased by the provision of the second abutting arm 52, thereby improving the connection stability. The two second abutting arms 52 abut against the two second groove bottoms 21311 one by one, so that the two second abutting arms 52 can 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 from 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 Fig.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 improve 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 rupturing the display screen 23.

[0087] In an exemplary embodiment, please combine Figure 4 , Figure 8 and Fig.12 , the direction of the elastic force of the first elastic member 40 on the vehicle body 10 intersects with the direction of the elastic force of the second elastic member 50 on the vehicle body 10, so that the directions of the reaction forces of the vehicle body 10 on the metal back plate 22 can intersect, and when the external force on the display device 20 is in the same direction as one of the reaction forces, the other reaction force can still ensure the connection stability between the display device 20 and the vehicle body 10. In the embodiment of the present disclosure, the direction of the elastic force of the first elastic member 40 on the vehicle body 10 intersects perpendicularly with the direction of the elastic force of the second elastic member 50 on the vehicle body 10.

[0088] In an exemplary embodiment, please combine Figure 3 , Figure 5 and Fig. 9 , the first side surface 211 has a mounting groove 600, the housing assembly 21 is provided with a connecting wall 214, the connecting wall 214 is received 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 housing assembly 21 is located at the connecting wall 214 inside the housing assembly 21, which can greatly compress the frame width of the housing assembly 21 surrounding the display screen 23, so that the display screen 23 has an ultra-narrow frame structure on the outer side. In the disclosed embodiment, 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 housing 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 plate 231 is bonded to the connecting wall 214 , the side of the glass cover plate 231 away from the connecting wall 214 is flush with the first side surface 211 , making the appearance of the display device 20 more beautiful, and the ultra-thin structure fits tightly and perfectly with the vehicle body 10 , forming a 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 It can be seen that the conventional installation method of the vehicle-mounted display screen 23 will cause the frame to be widened, and the length m of the pasting area 700 will be increased, which will lead to the thickening of the entire device and increase the thickness h of the pasting area 700. In addition, this pasting method will also cause a step n between the shell component 21 and the glass cover plate 231, affecting the appearance. In the disclosed embodiment, an external pasting structure is adopted to optimize the length m and the step n of the pasting area 700, and overlap the thickness h of the pasting area 700 into the thickness of the shell component 21 itself, so that the display screen 23 is installed on the shell component 21 without increasing the overall thickness.

[0092] In an exemplary embodiment, please combine Figures 3 to 5 , Figures 7 to 10 and Fig.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, thereby increasing the connection area between the front housing 216 and the rear housing 217, thereby increasing the connection stability between the front housing 216 and the rear housing 217. The overlapping position surrounds the display screen 23, thereby improving the sealing performance of the housing assembly 21 to the display screen 23, and preventing water vapor, dust, etc. from entering the housing assembly 21 to affect the normal operation of the display.

[0093] The front shell 216 and the rear shell 217 enclose the installation space 100, the first side 211 is located at the front shell 216, and the second side 212 is located at the rear shell 217. The display device 20 also includes a fastener 24, which is connected between the rear shell 217 and the metal back plate 22, and can abut the display screen 23 against the connecting wall 214. There are multiple fasteners 24, which are evenly distributed, and can connect the rear shell 217 with the metal back plate 22. Since the display screen 23 is connected to the metal back plate 22, as the fasteners 24 are locked, the display screen 23 can drive the connecting wall 214, and then drive the front shell 216 to move toward the rear shell 217, so that through the above locking process, the display screen 23 and the rear shell 217 can clamp the front shell 216 to form a sandwich structure, thereby making the connection between the front shell 216 and the rear shell 217 tighter, which can effectively solve the problem of gaps between the front shell 216 and the rear shell 217.

[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.
