Description

Technical Field

[0001] This application relates to display technology, specifically to screen display technology, and more particularly to an in-vehicle display screen and a vehicle. Background Technology

[0002] In today's digital age, displays hold immense significance, impacting all aspects of people's lives, work, entertainment, and social development. As society progresses, smart cars are gradually becoming a part of daily life. The in-vehicle displays installed in these cars serve as crucial windows for users to access information, providing driving assistance such as reversing cameras and navigation, facilitating control of in-vehicle equipment like air conditioning and audio systems, and comprehensively enhancing cabin performance and the overall passenger experience.

[0003] Currently, in-vehicle displays typically attach the screen module to the rear housing using screws and adhesive, and then the rear housing bracket is fixed to the vehicle's components. Because vehicles operate in the external environment, they frequently encounter scenarios such as acceleration, sudden braking, collisions, and bumps. For example, when driving on uneven roads, this method of fixing the display can easily lead to screws loosening and adhesive weakening, causing the screen module to shift. In severe cases, this can result in the screen cracking. If a collision or sudden braking occurs, the display components are highly susceptible to detachment and breakage, potentially causing cuts and scratches to users from the detached, deformed, or broken equipment and its parts, threatening their safety.

[0004] Therefore, how to solve the above problems is a hot topic of research for people in this field. Summary of the Invention

[0005] This application provides an in-vehicle display screen and a vehicle, which can improve the stability and reliability of the in-vehicle display screen components, thereby reducing the possibility of cracking of the in-vehicle display screen components, improving user safety, meeting automotive requirements, and enhancing market competitiveness.

[0006] In a first aspect, embodiments of this application provide an in-vehicle display screen, which includes a mid-frame, a backlight module, and a screen module. The mid-frame surrounds the backlight module, and the screen module is fixed to the top of the mid-frame and the top of the backlight module. The mid-frame is provided with a first positioning portion, and the backlight module is provided with a second positioning portion at a position opposite to the first positioning portion. The first and second positioning portions are used for positioning the mid-frame and the backlight module. The mid-frame is provided with a first fixing portion, and the backlight module is provided with a second fixing portion at a position opposite to the first fixing portion. The first fixing portion and the second fixing portion are fixedly connected. The distance between the first positioning portion and a first corner of the screen module is less than the distance between the first fixing portion and the first corner.

[0007] For example, the screen module is rectangular, and the screen module includes a long side and a wide side. The corner is the intersection of the long side and the wide side, and the first corner is one or more of the corners.

[0008] Optionally, the vehicle display screen can be installed in a mobile terminal, such as a vehicle, and the vehicle display screen can be installed inside the vehicle's cabin.

[0009] Some automotive displays typically attach the screen module to the rear housing using screws and adhesive, and then fix the rear housing bracket to the vehicle components. However, if the vehicle is driven on uneven roads, this method of fixing the display can easily lead to loose screws and reduced adhesive strength, causing the screen module to shift and potentially cracking. This application addresses this issue by incorporating a first and second positioning part into the automotive display. This allows for precise positioning of the mid-frame at a predetermined location on the backlight module, accurately determining the relative position between the mid-frame and the backlight module, reducing assembly errors, and ensuring the display meets design precision requirements. Furthermore, the positioning part effectively restricts the movement and rotation of the mid-frame, enabling it to better withstand external forces and vibrations during use. This reduces the risk of the mid-frame detaching or cracking due to significant deformation, improving the stability and reliability of the mid-frame. Ultimately, this enhances the reliability and lifespan of the automotive display, improves user safety, meets automotive-grade requirements, and increases market competitiveness.

[0010] Furthermore, this application provides a first fixing part and a second fixing part in the vehicle display screen. The first fixing part and the second fixing part are fixedly connected to achieve relative fixation between the middle frame and the backlight module, ensuring a tight connection between the middle frame and the backlight module. This further reduces the risk of the middle frame falling off or breaking due to large deformation, and can improve the stability and reliability of the vehicle display screen components.

[0011] In addition, this application places the first positioning part closer to the corner of the screen module than the first fixing part, which can improve the positioning accuracy, better constrain the movement and rotation freedom of the middle frame, effectively improve the stability and rigidity of the structure, thereby achieving the best positioning and fixing effect, improving the stability and reliability of the middle frame, reducing the risk of the middle frame falling off or breaking due to large deformation, and improving the stability and reliability of the vehicle display components.

[0012] In summary, this application can improve the stability and reliability of in-vehicle display components, thereby reducing the possibility of cracking, improving user safety, meeting automotive-grade requirements, and enhancing market competitiveness.

[0013] In one possible implementation of the first aspect, the first positioning part is located in the long side direction of the screen module, the length of the long side of the screen module is L0, and the distance from the first positioning part to one end of the long side of the screen module is Lc, where Lc satisfies the following condition: 0 < Lc < L0 / 8.

[0014] The above embodiments illustrate the conditions that the placement position of the first positioning part in the long side direction of the screen module must meet. Through experiments, system simulations were performed to examine the placement position of the first positioning part and the stability and reliability of the corresponding mid-frame and backlight module at that position, thereby finding the optimal placement position of the first positioning part for the stability and reliability of the mid-frame and backlight module. When the placement position of the first positioning part meets the above conditions, the stability and reliability of the mid-frame and backlight module are optimal, minimizing the risk of the mid-frame detaching or breaking due to large deformation, and improving the stability and reliability of the vehicle display components.

[0015] In another possible implementation of the first aspect, the first positioning part is located in the wide side direction of the screen module, the length of the wide side of the screen module is W0, and the distance from the first positioning part to one end of the wide side of the screen module is Wc, where Wc satisfies the following condition: 0 < Wc < W0 / 8.

[0016] The above embodiments illustrate the conditions that the placement position of the first positioning part in the wide side direction of the screen module must meet. Through experiments, system simulations were performed to examine the placement position of the first positioning part and the stability and reliability of the corresponding mid-frame and backlight module at that position, thereby finding the optimal placement position of the first positioning part for the stability and reliability of the mid-frame and backlight module. When the placement position of the first positioning part meets the above conditions, the stability and reliability of the mid-frame and backlight module are optimal, minimizing the risk of the mid-frame detaching or breaking due to large deformation, and improving the stability and reliability of the vehicle display components.

[0017] In another possible implementation of the first aspect, the first fixing part is located in the long side direction of the screen module, the length of the long side of the screen module is L0, and the distance from the first fixing part to one end of the long side of the screen module is L, where L satisfies the following condition: 0 < L < L0 / 4.

[0018] The above embodiments illustrate the conditions that the placement position of the first fixing part in the long side direction of the screen module must meet. Through experiments, system simulations were performed to examine the placement position of the first fixing part and the stability and reliability of the corresponding mid-frame and backlight module at that position, thereby finding the optimal placement position of the first fixing part for the stability and reliability of the mid-frame and backlight module. When the placement position of the first fixing part meets the above conditions, the stability and reliability of the mid-frame and backlight module are optimal, minimizing the risk of the mid-frame detaching or breaking due to large deformation, and improving the stability and reliability of the vehicle display components.

[0019] In another possible implementation of the first aspect, the first fixing part is located in the direction of the wide side of the screen module, the length of the wide side of the screen module is W0, and the distance from the first positioning part to one end of the wide side of the screen module is W, where W satisfies the following condition: 0 < W < W0 / 4.

[0020] The above embodiments illustrate the conditions that the placement position of the first fixing part in the wide side direction of the screen module must meet. Through experiments, system simulations were performed to examine the placement position of the first fixing part and the stability and reliability of the corresponding mid-frame and backlight module at that position, thereby finding the optimal placement position of the first fixing part for the stability and reliability of the mid-frame and backlight module. When the placement position of the first fixing part meets the above conditions, the stability and reliability of the mid-frame and backlight module are optimal, minimizing the risk of the mid-frame detaching or breaking due to large deformation, and improving the stability and reliability of the vehicle display components.

[0021] In another possible embodiment of the first aspect, the mid-frame includes a border and a first extension, the first extension protruding from the inner surface of the border. The backlight module includes a base plate and a second extension, the second extension protruding from the surface of the base plate facing the screen module. The first extension and the second extension are stacked along a second direction, the second direction being perpendicular to the first direction. The distance between the second extensions in the first direction is S. The distance between the stacked areas of the first extension and the second extension in the second direction in the first direction is q, where q satisfies the condition: 0 < q < S.

[0022] In the above embodiments, the distance between the overlapping areas of the first extension and the second extension in the second direction in the first direction needs to be less than the distance between the second extension in the first direction. That is, there is a region in the second extension that is not overlapped with the first extension in the first direction. The backlight module usually includes a light-emitting element. When this part of the non-overlapping area surrounds the light-emitting element, it can be used to prevent light leakage of the backlight module, thereby avoiding light leakage of the vehicle display screen, meeting automotive-grade requirements, and improving market competitiveness.

[0023] In another possible implementation of the first aspect, the first positioning part includes a positioning post, and the second positioning part includes a positioning hole, with the positioning post inserted into the positioning hole. Alternatively, the first positioning part includes a positioning hole, and the second positioning part includes a positioning post, with the positioning post inserted into the positioning hole.

[0024] In the above embodiments, the design of the positioning post and positioning hole can not only be used to set the middle frame at the predetermined position of the backlight module, accurately determine the relative position between the middle frame and the backlight module, but also be used to fix the position of the middle frame and the backlight module to remain relatively unchanged, preventing the middle frame from shifting or being damaged due to vibration, impact, etc., thereby improving the stability and reliability of the middle frame, reducing the risk of the middle frame falling off or breaking due to large deformation, improving user safety, meeting automotive-grade requirements, and enhancing market competitiveness.

[0025] In another possible embodiment of the first aspect, the first fixing part and the second fixing part are fixedly connected by a fixing medium, which includes a screw, and the positioning post is circular. Optionally, the fixing medium also includes at least one of the following: adhesive backing, dispensing adhesive, clips, rivets, bolts and nuts, hot melt adhesive, hot melt gaskets, or hot melt welding wire. Optionally, the positioning post may also be at least one of the following: oblong, square, rectangular, or irregularly shaped.

[0026] When the first and second fixing parts are fixedly connected by a fixing medium, screws are used for the connection. This allows for relative fixation between the middle frame and the backlight module, ensuring a tight connection between them. This further reduces the risk of the middle frame detaching or breaking due to large deformation, thus improving the stability and reliability of the vehicle display components. Moreover, the fixing medium is screws, and the circular design of the positioning posts is simple, easy to manufacture, and convenient to install.

[0027] In another possible embodiment of the first aspect, a groove is provided at the bottom of the mid-frame, and a first fastener is disposed within the groove. The mid-frame and the backlight module are fixedly connected by the first fastener. The first fastener includes adhesive backing. Optionally, the first fastener further includes at least one of the following: dispensing adhesive, clips, hot melt adhesive, hot melt pads, or hot melt welding wire.

[0028] In the above embodiment, the bottom of the middle frame is provided with a groove that can accommodate the first fastener, which can prevent the first fastener from being seen from the outside, making it more visually appealing and improving market competitiveness.

[0029] In another possible implementation of the first aspect, a second fastener is provided at the top of the mid-frame, and the screen module and the top of the mid-frame are fixedly connected by the second fastener. Optionally, the second fastener includes at least one of the following: adhesive backing, dispensing adhesive, clip, hot melt adhesive, hot melt pad, or hot melt welding wire.

[0030] In the above embodiments, the top of the screen module and the middle frame are fixedly connected by the second fastener, which can achieve relative fixation between the top of the screen module and the middle frame, ensuring a tight connection between the top of the screen module and the middle frame, thereby reducing the possibility of screen cracking caused by screen module displacement, and improving the stability and reliability of the vehicle display components.

[0031] In another possible implementation of the first aspect, a third fastener is provided on the top of the backlight module, and the tops of the screen module and the backlight module are fixedly connected by the third fastener. Optionally, the third fastener includes at least one of the following: adhesive backing, dispensing adhesive, clip, hot melt adhesive, hot melt pad, or hot melt welding wire.

[0032] In the above embodiments, the tops of the screen module and the backlight module are fixedly connected by a third fastener, which can achieve relative fixation between the tops of the screen module and the backlight module, ensuring a tight connection between the tops of the screen module and the backlight module, thereby reducing the possibility of screen cracking caused by screen module displacement, and improving the stability and reliability of the vehicle display components.

[0033] In another possible implementation of the first aspect, the middle frame includes a border, the edge of the screen module along the thickness direction is disposed opposite to the inner surface of the border, and the distance between the edge of the screen module along the thickness direction and the inner surface of the border is less than a first threshold.

[0034] In the above embodiments, the gap between the screen module and the frame is less than the first threshold, which can improve the visual aesthetics, optimize the gap, improve space utilization, enhance the appearance and refinement, reduce the visual interference of the frame when the user uses the screen, allow the user to focus on the screen content, and enable the user to obtain a more immersive user experience.

[0035] In another possible implementation of the first aspect, the backlight module includes a second extension, which includes a first side and a second side. The mid-frame includes a border, the first side being disposed opposite to the inner surface of the border, the second side being disposed opposite to the inner surface of the border, and the edge of the screen module along the thickness direction being located between the first side and the inner surface of the border.

[0036] In the above embodiments, the edge of the screen module along the thickness direction is located between the first side and the inner surface of the frame, which can prevent the fasteners used to fix the top of the screen module and the middle frame from being visible from the outside, making it more aesthetically pleasing and improving market competitiveness.

[0037] In another possible implementation of the first aspect, the screen module is rectangular, and includes a first long side, a second long side, a first wide side, and a second wide side. The middle frame has two first positioning portions and two first fixing portions along the first long side, and two first positioning portions and two first fixing portions along the second long side. The middle frame also has two first positioning portions and two first fixing portions along the first wide side, and two first positioning portions and two first fixing portions along the second wide side.

[0038] In the above embodiments, the middle frame is provided with two first positioning parts and two first fixing parts along each long side and each wide side of the screen module, which can improve the stability and reliability of the middle frame and the backlight module, and can minimize the risk of the middle frame falling off or breaking due to large deformation, thereby improving the stability and reliability of the vehicle display components.

[0039] In another possible implementation of the first aspect, the mid-frame is made of plastic and / or metal, the metal including alloys, and the alloys including at least one of stainless steel, aluminum alloy, titanium alloy, or magnesium alloy. The backlight module is made of an alloy.

[0040] Optionally, a glossy finish can be applied to the outer surface of the mid-frame, such as a metallic coating like silver or copper plating, which can make the outer surface of the mid-frame more aesthetically pleasing, enhance the appearance of the vehicle display screen, and improve its market competitiveness.

[0041] In another possible implementation of the first aspect, the processing technology of the middle frame includes at least one of the following: two-color anodizing process, sandblasting and anodizing combined process, sandblasting and computer digital control (CNC) and electrophoresis combined process, two-color injection molding process, two-color spraying process, material and spraying combined process, material and electroplating combined process, material and screen printing combined process, or material and pad printing combined process.

[0055] Currently, smart cars are gradually entering people's daily lives. The in-vehicle displays installed in smart cars are an important window for users to obtain information. They can provide users with driving assistance such as reversing images and navigation, and facilitate users to control in-vehicle equipment such as air conditioning and audio, thus comprehensively empowering the improvement of cabin performance and riding experience.

[0056] In some solutions, the in-vehicle display screen module is fixed to the rear shell using screws and adhesive, and the rear shell bracket is fixed to the vehicle components. Because vehicles need to travel in the external environment, they frequently encounter scenarios such as acceleration, sudden braking, collisions, and bumps. For example, when driving on uneven roads, this method of fixing the in-vehicle display screen can easily lead to screws loosening and adhesive weakening, causing the screen module to shift, and in severe cases, potentially causing the screen to crack. If the vehicle collides or brakes suddenly, the in-vehicle display screen components are easily detached and broken, potentially causing cuts and scratches to users from the detached, deformed, or broken equipment and its parts, threatening user safety.

[0057] In view of this, this application provides an in-vehicle display screen and a vehicle, which can improve the stability and reliability of the in-vehicle display screen components, thereby reducing the possibility of cracking of the in-vehicle display screen components, improving user safety, meeting automotive requirements, and enhancing market competitiveness.

[0058] The system architecture used in the embodiments of this application is described below. It should be understood that as system architectures evolve and new business scenarios emerge, the technical solutions provided in this application may also be applicable to similar technical problems.

[0059] Please see Figure 1 This application provides an in-vehicle display screen 100, including a mid-frame 10, a backlight module 20, and a screen module 30. Wherein:

[0060] The mid-frame 10 surrounds the backlight module 20. "Surrounds" means that the mid-frame 10 is located around the backlight module 20, forming a complete enclosure or semi-enclosure around it. For example, combined with... Figure 1 The middle frame 10 surrounds the backlight module 20 along the y-direction, and the middle frame 10 also surrounds the backlight module 20 along the z-direction.

[0061] The middle frame 10 is used to fix the screen module 30. For example, the screen module 30 is fixed to the top of the middle frame 10. The top of the middle frame 10 refers to the top of the middle frame 10 along the thickness direction of the screen module 30, such as the top of the middle frame 10 along the x-direction.

[0062] The backlight module 20 is used to fix the screen module 30. Exemplarily, the screen module 30 is fixed to the top of the backlight module 20. Here, the top of the backlight module 20 refers to the top of the backlight module 20 along the thickness direction of the screen module 30, such as the top of the backlight module 20 along the x-direction. Exemplarily, combined with... Figure 2 , Figure 2 for Figure 1 The diagram shows a cross-sectional view of F along the z direction, with the screen module 30 fixed to the top of the middle frame 10 and the top of the backlight module 20.

[0063] The backlight module 20 is also used to provide sufficient brightness and uniformly distributed light to the screen module 30, enabling the screen module 30 to display images (such as graphics, characters, etc.). Exemplarily, the backlight module 20 includes a light source, such as a light-emitting diode (LED) or a cold cathode fluorescent lamp (CCFL). Optionally, the backlight module 20 also includes optical films (such as light guide plates, reflective sheets, diffusers, brightness enhancement films (or prism sheets)), castings for fixing the lamps and films, etc. Exemplarily, combined with... Figure 2 , Figure 2This is a cross-sectional schematic diagram of a portion of a vehicle-mounted display screen provided in an embodiment of this application, such as... Figure 2 for Figure 1 The diagram shows a cross-sectional view of the F region of the vehicle display screen 100 along the z direction. The backlight module 20 includes a light source 203, which faces the screen module 30 and can provide sufficient brightness and uniformly distributed light to the screen module 30.

[0064] The screen module 30 is fixed to the top of the mid-frame 10 and the top of the backlight module 20, and is used to display images based on the light provided by the backlight module 20. For example, combined with Figure 2 The screen module 30 is fixed along the x-direction to the top of the middle frame 10 and the top of the backlight module 20, and the light provided by the backlight module 20 can reach the screen module 30 along the x-direction. For example, the screen module 30 includes liquid crystal substrate glass, cover glass, ultra-thin flexible glass, or mirror glass, etc.

[0065] In one possible implementation, the middle frame 10 is provided with a first positioning part 101, and the backlight module 20 is provided with a second positioning part 201 at a position opposite to the first positioning part 101 (e.g., Figure 1 The second positioning part 201 shown is used for positioning the middle frame 10 and the backlight module 20.

[0066] In one possible scenario, the first positioning part 101 includes a positioning hole 1011, and the second positioning part 201 includes a positioning post 2011, which is inserted into the positioning hole 1011. For example, in combination with... Figure 3 , Figure 3 This is a cross-sectional schematic diagram of a portion of another vehicle-mounted display screen provided in an embodiment of this application, such as... Figure 3 for Figure 1 The diagram shows a cross-sectional view of region A along the z-direction of the vehicle display screen 100. The mid-frame 10 is provided with positioning holes 1011. Positioning posts 2011 are provided on the surface of the backlight module 20 facing the screen module 30 at positions opposite to the positioning holes 1011. The positioning posts 2011 are inserted into the positioning holes 1011, thereby fixing the mid-frame 10 in a predetermined position on the backlight module 20. This prevents the mid-frame 10 from shifting or being damaged due to vibration, impact, or other reasons, thus improving the stability and reliability of the mid-frame 10.

[0067] In another possible scenario, the first positioning part 101 includes a positioning post 1012, and the second positioning part 201 includes a positioning hole 2012, with the positioning post 1012 inserted into the positioning hole 2012. For example, in conjunction with... Figure 4 , Figure 4 This is a cross-sectional schematic diagram of a portion of another vehicle-mounted display screen provided in an embodiment of this application, such as... Figure 4 for Figure 1The diagram shows another cross-sectional view of region A along the z-direction of the vehicle-mounted display screen 100. The mid-frame 10 is provided with a positioning post 1012. The surface of the backlight module 20 facing the screen module 30 has a positioning hole 2012 at a position opposite to the positioning post 1012. The positioning post 1012 is inserted into the positioning hole 2012, thereby fixing the mid-frame 10 in a predetermined position on the backlight module 20, preventing displacement or damage to the mid-frame 10 due to vibration, impact, etc., and improving the stability and reliability of the mid-frame 10. Exemplarily, the positioning post is circular. Optionally, the positioning post may also be at least one of the following: oblong, square, rectangular, or irregularly shaped.

[0068] It should be understood that the above describes the first positioning part and the second positioning part using positioning pins and positioning holes. In actual implementation, the first positioning part and the second positioning part may have other possible designs, such as positioning pins, positioning grooves and positioning bosses, guide holes and guide pins, etc., which will not be listed here.

[0069] In one possible implementation, combined with Figure 5 , Figure 5 This is a cross-sectional schematic diagram of a portion of another vehicle-mounted display screen provided in an embodiment of this application, such as... Figure 5 for Figure 1 The diagram shows a cross-sectional view of region A along the z-direction of the vehicle display screen 100. The mid-frame 10 is provided with a first fixing part 102, and the backlight module 20 is provided with a second fixing part 202 at a position opposite to the first fixing part 102. The first fixing part 102 and the second fixing part 202 are fixedly connected, achieving relative fixation between the mid-frame 10 and the backlight module 20, ensuring a tight connection between the mid-frame 10 and the backlight module 20, and improving the stability and reliability of the components of the vehicle display screen 100 (such as the mid-frame 10).

[0070] In one possible implementation, the distance between the first positioning part 101 and the first corner of the screen module 30 is less than the distance between the first fixing part 102 and the first corner. The first corner can be one or more corners. Figure 6The second positioning part 201 includes a second positioning part 201a, and the second fixing part 202 includes a second fixing part 202a. The first corner is point B. Therefore, the distance between the second positioning part 201a and point B is less than the distance between the second fixing part 202a and point B. That is, the second positioning part 201a is closer to the corner (point B) of the screen module 30 than the second fixing part 202a. Thus, the first positioning part 101 is closer to the corner of the screen module 30 than the first fixing part 102, which improves positioning accuracy, better constrains the movement and rotational freedom of the middle frame 10, effectively improves the stability and rigidity of the structure, thereby achieving optimal positioning and fixing effects, enhancing the stability and reliability of the middle frame 10, reducing the risk of the middle frame 10 falling off or breaking due to large deformation, and improving the stability and reliability of the vehicle display screen 100 components.

[0071] The aforementioned vehicle-mounted display screen 100 is provided with a first positioning part 101 and a second positioning part 201, which can be used to position the middle frame 10 at a predetermined position on the backlight module 20. This allows for precise determination of the relative position between the middle frame 10 and the backlight module 20, reducing assembly errors and ensuring that the vehicle-mounted display screen 100 meets the design precision requirements. Furthermore, the design of the positioning parts (i.e., the first positioning part 101 and the second positioning part 201) effectively restricts the movement and rotation of the middle frame 10, enabling it to better withstand external forces and vibrations during use. This reduces the risk of the middle frame 10 falling off or breaking due to large deformation, improving the stability and reliability of the middle frame 10. Consequently, this enhances the reliability and service life of the vehicle-mounted display screen 100, improves user safety, meets automotive-grade requirements, and enhances market competitiveness.

[0072] Furthermore, the vehicle display screen 100 is provided with a first fixing part 102 and a second fixing part 202. The first fixing part 102 and the second fixing part 202 are fixedly connected to achieve relative fixation between the middle frame 10 and the backlight module 20, ensuring a tight connection between the middle frame 10 and the backlight module 20. This further reduces the risk of the middle frame 10 falling off or breaking due to large deformation, and can improve the stability and reliability of the vehicle display screen 100 components.

[0073] In addition, the first positioning part 101 in the above-mentioned vehicle display screen 100 is closer to the corner of the screen module 30 than the first fixing part 102, which can improve the positioning accuracy, better constrain the movement and rotation freedom of the middle frame 10, effectively improve the stability and rigidity of the structure, thereby achieving the best positioning and fixing effect, improving the stability and reliability of the middle frame 10, reducing the risk of the middle frame 10 falling off or breaking due to large deformation, and improving the stability and reliability of the components of the vehicle display screen 100.

[0074] In summary, this application can improve the stability and reliability of the in-vehicle display screen 100 components, thereby reducing the possibility of cracking of the in-vehicle display screen 100 components, improving user safety, meeting automotive-grade requirements, and enhancing market competitiveness.

[0075] The following describes some possible designs of embodiments of this application.

[0076] In one possible implementation, the first positioning part 101 and the first fixing part 102 are disposed near the corner of the middle frame 10. Similarly, the second positioning part 201 and the second fixing part 202 are disposed near the corner of the backlight module 20. The corner is the intersection of the long side and the wide side. Exemplarily, the screen module 30 is rectangular, and the screen module 30 includes a long side and a wide side, combined with... Figure 6 The screen module 30 includes two long sides and two wide sides, with four intersection points between the long sides and the wide sides, namely points B, C, D, and E. The corners include points B, C, D, and E. The second positioning part 201 includes a second positioning part 201a on the long side BD, closer to point B, and the second fixing part 202 includes a second fixing part 202a on the long side BD, also closer to point B. Compared to the centerline n in the wide side direction of the screen module 30, the second positioning part 201a and the second fixing part 202a are both closer to the corner point B.

[0077] In one possible implementation, the first positioning part is located along the long side of the screen module, the length of the long side of the screen module is L0, and the distance from the first positioning part to one end of the long side of the screen module is Lc, where Lc satisfies the condition: 0 < Lc < L0 / 8. Similarly, the distance from the second positioning part to one end of the long side of the screen module is Lc, where Lc satisfies the condition: 0 < Lc < L0 / 8. For example, combined with... Figure 6 The second positioning part 201a is located along the long side BD of the screen module 30, the length of the long side BD is L0, and the distance from the second positioning part 201a to one end of the long side BD (point B) is Lc. Then Lc satisfies 0 < Lc < L0 / 8. Similarly, the second positioning part 201b is located along the long side BD, and the distance from the second positioning part 201b to one end of the long side BD (point D) is Lc. Then Lc satisfies 0 < Lc < L0 / 8. Furthermore, combining... Figure 6The second positioning part 201c is located along the long side of the CE axis of the screen module 30, with a length of L0. The distance from the second positioning part 201c to one end (point C) of the long side of the CE axis is Lc, where Lc satisfies 0 < Lc < L0 / 8. Similarly, the second positioning part 201d is located along the long side of the CE axis, with a distance of Lc from the second positioning part 201d to one end (point E) of the long side of the CE axis, where Lc satisfies 0 < Lc < L0 / 8. For example, by conducting system simulations of the setting position of the first positioning part and the corresponding stability and reliability of the mid-frame and backlight module at that setting position, the optimal setting position of the first positioning part for the stability and reliability of the mid-frame and backlight module can be found. One possible implementation is as follows... Figure 7 In the simulation data of Scheme 1, when the setting position of the first positioning part does not satisfy 0 < Lc < L0 / 8, the maximum stress at the R-corner of the middle frame is 24.77 MPa. In one embodiment of this application, as... Figure 7 In the simulation data of Scheme 2, when the setting position of the first positioning part satisfies 0 < Lc < L0 / 8, the maximum stress at the R-corner of the middle frame is 16.79 MPa, which is much less than 24.77 MPa. In other words, when the setting position of the first positioning part meets the above conditions, the maximum stress at the R-corner of the middle frame is smaller, the stability and reliability of the middle frame and the backlight module are optimal, and it is less prone to deformation. This can minimize the risk of the middle frame falling off or breaking due to large deformation, and improve the stability and reliability of the vehicle display components.

[0078] In another possible implementation, the first positioning part is located along the width of the screen module, the length of the width of the screen module is W0, and the distance from the first positioning part to one end of the width of the screen module is Wc, where Wc satisfies the condition: 0 < Wc < W0 / 8. Similarly, the distance from the second positioning part to one end of the width of the screen module is Wc, where Wc satisfies the condition: 0 < Wc < W0 / 8. For example, combined with... Figure 6 The second positioning part 201e is located along the BC width direction of the screen module 30, the length of the BC width is W0, and the distance from the second positioning part 201e to one end of the BC width (point B) is Wc. Then Wc satisfies 0 < Wc < W0 / 8. Similarly, the second positioning part 201f is located along the BC width direction, and the distance from the second positioning part 201f to one end of the BC width (point C) is Wc. Then Wc satisfies 0 < Wc < W0 / 8. Furthermore, combining... Figure 6The second positioning part 201g is located in the DE wide side direction of the screen module 30, the length of the DE wide side is W0, and the distance from the second positioning part 201g to one end (point D) of the DE wide side is Wc, then Wc satisfies 0 < Wc < W0 / 8. Similarly, the second positioning part 201h is located in the DE wide side direction, and the distance from the second positioning part 201h to one end (point E) of the DE wide side is Wc, then Wc satisfies 0 < Wc < W0 / 8. Similarly, through experiments, the setting position of the first positioning part and the stability and reliability of the corresponding middle frame and backlight module under that setting position are systematically simulated to find the setting position of the first positioning part corresponding to the optimal stability and reliability of the middle frame and backlight module. In one possible implementation, as follows... Figure 7 In the simulation data of Scheme 1, when the setting position of the first positioning part does not satisfy 0 < Wc < W0 / 8, the maximum stress at the R-corner of the middle frame is 24.77 MPa. In one embodiment of this application, as... Figure 7 In the simulation data of Scheme 2, when the setting position of the first positioning part satisfies 0 < Wc < W0 / 8, the maximum stress at the R-corner of the middle frame is 16.79 MPa, which is much less than 24.77 MPa. In other words, when the setting position of the first positioning part meets the above conditions, the maximum stress at the R-corner of the middle frame is smaller, the stability and reliability of the middle frame and the backlight module are optimal, and it is less prone to deformation. This can minimize the risk of the middle frame falling off or breaking due to large deformation, and improve the stability and reliability of the vehicle display components.

[0079] In one possible implementation, the first fixing part is located along the long side of the screen module, the length of the long side of the screen module is L0, and the distance from the first fixing part to one end of the long side of the screen module is L, where L satisfies the condition: 0 < L < L0 / 4. Similarly, the distance from the second fixing part to one end of the long side of the screen module is L, where L satisfies the condition: 0 < L < L0 / 4. For example, combined with... Figure 6 The second fixing part 202a is located along the long side BD of the screen module 30, the length of the long side BD is L0, and the distance from the second fixing part 202a to one end of the long side BD (point B) is L. Then L satisfies 0 < L < L0 / 4. Similarly, the second fixing part 202b is located along the long side BD, and the distance from the second fixing part 202b to one end of the long side BD (point D) is L. Then L satisfies 0 < L < L0 / 4. Furthermore, combining... Figure 6The second fixing part 202c is located along the long side of CE of the screen module 30, the length of the long side of CE is L0, and the distance from the second fixing part 202c to one end of the long side of CE (point C) is L, then L satisfies 0 < L < L0 / 4. Similarly, the second fixing part 202d is located along the long side of CE, and the distance from the second fixing part 202d to one end of the long side of CE (point E) is L, then L satisfies 0 < L < L0 / 4. Similarly, through experiments, system simulations are performed on the setting position of the first fixing part and the stability and reliability of the corresponding middle frame and backlight module at that setting position, thereby finding the setting position of the first fixing part corresponding to the optimal stability and reliability of the middle frame and backlight module. In one possible implementation, as follows... Figure 8 In the simulation data of Scheme 3, when the setting position of the first fixing part does not satisfy 0 < L < L0 / 4, the maximum stress at the R-corner of the middle frame is 27.56 MPa. In one embodiment of this application, as... Figure 8 In the simulation data of Scheme 4, when the setting position of the first fixing part satisfies 0 < L < L0 / 4, the maximum stress at the R-corner of the middle frame is 18.286 MPa, which is much less than 27.56 MPa. In other words, when the setting position of the first fixing part meets the above conditions, the maximum stress at the R-corner of the middle frame is smaller, the stability and reliability of the middle frame and the backlight module are optimal, and it is less prone to deformation. This can minimize the risk of the middle frame falling off or breaking due to large deformation, and improve the stability and reliability of the vehicle display components.

[0080] In another possible implementation, the first fixing part is located along the wide side of the screen module, the length of the wide side of the screen module is W0, and the distance from the first fixing part to one end of the wide side of the screen module is W, where W satisfies the condition: 0 < W < W0 / 4. Similarly, the distance from the second fixing part to one end of the wide side of the screen module is W, where W satisfies the condition: 0 < W < W0 / 4. For example, combined with... Figure 6 The second fixing part 202e is located along the BC width direction of the screen module 30, the length of the BC width is W0, and the distance from the second fixing part 202e to one end of the BC width (point B) is W. Then W satisfies 0 < W < W0 / 4. Similarly, the second fixing part 202f is located along the BC width direction, and the distance from the second fixing part 202f to one end of the BC width (point C) is W. Then W satisfies 0 < W < W0 / 4. Furthermore, combining... Figure 6The second fixing part 202g is located in the DE wide side direction of the screen module 30, the length of the DE wide side is W0, and the distance from the second fixing part 202g to one end (point D) of the DE wide side is W, then W satisfies 0 < W < W0 / 4. Similarly, the second fixing part 202h is located in the DE wide side direction, and the distance from the second fixing part 202h to one end (point E) of the DE wide side is W, then W satisfies 0 < W < W0 / 4. Similarly, through experiments, the system simulation of the setting position of the first fixing part and the stability and reliability of the corresponding middle frame and backlight module under this setting position is carried out to find the setting position of the first fixing part corresponding to the optimal stability and reliability of the middle frame and backlight module. In one possible implementation, as follows Figure 8 In the simulation data of Scheme 3, when the setting position of the first fixing part does not satisfy 0 < W < W0 / 4, the maximum stress at the R-corner of the middle frame is 27.56 MPa. In one embodiment of this application, as... Figure 8 In the simulation data of Scheme 4, when the setting position of the first fixing part satisfies 0 < W < W0 / 4, the maximum stress at the R-corner of the middle frame is 18.286 MPa, which is much less than 27.56 MPa. In other words, when the setting position of the first fixing part meets the above conditions, the maximum stress at the R-corner of the middle frame is smaller, the stability and reliability of the middle frame and the backlight module are optimal, and it is less prone to deformation. This can minimize the risk of the middle frame falling off or breaking due to large deformation, and improve the stability and reliability of the vehicle display components.

[0081] In one possible implementation, combined with Figure 9 The middle frame 10 includes a frame 104 and a first extension 103, the first extension 103 protruding from the inner surface 1041 of the frame 104. The backlight module 20 includes a base plate 205 and a second extension 204, the second extension 204 protruding from the surface of the base plate 205 facing the screen module 30. The first extension 103 and the second extension 204 are stacked along a second direction, which is perpendicular to the first direction. The second direction is the thickness direction of the screen module 30. The distance between the second extensions 204 in the first direction is S. The distance between the overlapping areas of the first extension 103 and the second extension 204 in the second direction is q, where q satisfies the condition: 0 < q < S, for example, q is 2S / 3, etc. That is, there is a region in the second extension 204 that is not stacked with the first extension 103 in the first direction (e.g., ...). Figure 9 The raised area on the left side of the second extension 204 in the middle), the backlight module 20 typically includes light-emitting elements (such as... Figure 9 The non-overlapping area of ​​the light-emitting element (203) can be used to prevent light leakage from the backlight module 20, thereby avoiding light leakage from the vehicle display screen 100, meeting automotive requirements, and improving market competitiveness.

[0082] In one possible implementation, the border 104 and the first extension 103 together form an accommodating space, and the screen module 30 is disposed within the accommodating space.

[0083] In one possible implementation, the first fixing part 102 and the second fixing part 202 are fixedly connected by a fixing medium, which includes screws. Optionally, the fixing medium also includes at least one of the following: adhesive, glue, clips, rivets, bolts and nuts, hot melt adhesive, hot melt gaskets, or hot melt welding wire. Taking screws as an example, the middle frame 10 has a first groove (i.e., the first fixing part 102 includes the first groove) at the bottom along the thickness direction of the screen module 30, and the backlight module 20 has a second groove (i.e., the second fixing part 202 includes the second groove) at the top along the thickness direction of the screen module 30. The first groove at the bottom of the middle frame 10 is fixedly connected to the second groove at the top of the backlight module 20 by screws.

[0084] In one possible implementation, combined with Figure 10 The bottom of the mid-frame 10 is provided with a groove 105, and a first fixing member 40 is disposed within the groove 105. The mid-frame 10 and the backlight module 20 are fixedly connected by the first fixing member 40. The bottom of the mid-frame 10 is the bottom of the mid-frame 10 along the thickness direction of the screen module 30. Exemplarily, the first fixing member 40 includes adhesive backing. Optionally, the first fixing member 40 further includes at least one of the following: dispensing adhesive, clips, hot melt adhesive, hot melt pads, or hot melt welding wire.

[0085] Another possible implementation method is to combine Figure 10 A second fastener 50 is provided on the top of the middle frame 10, and the top of the screen module 30 and the middle frame 10 are fixedly connected by the second fastener 50. Exemplarily, the second fastener 50 includes at least one of the following: adhesive backing, dispensing adhesive, clip, hot melt adhesive, hot melt pad, or hot melt welding wire.

[0086] Another possible implementation method is to combine Figure 10 A third fastener 60 is provided on the top of the backlight module 20, and the tops of the screen module 30 and the backlight module 20 are fixedly connected by the third fastener 60. Exemplarily, the third fastener 60 includes at least one of the following: adhesive backing, dispensing adhesive, clips, hot melt adhesive, hot melt pads, or hot melt welding wire. Optionally, combined with... Figure 10 The second fastener 50 and the third fastener 60 may be different fasteners. Alternatively, the second fastener 50 and the third fastener 60 may be different parts of the same fastener, for example, combined. Figure 11The second fastener 50 is the first part of the fourth fastener 70, and the first part of the fourth fastener 70 is used to fix the top of the screen module 30 and the middle frame 10. The third fastener 60 is the second part of the fourth fastener 70, and the second part of the fourth fastener 70 is used to fix the top of the screen module 30 and the backlight module 20.

[0087] In one possible implementation, combined with Figure 9 The middle frame 10 includes a bezel 104. The edge of the screen module 30 along the thickness direction is disposed opposite to the inner surface 1041 of the bezel 104. The distance between the edge of the screen module 30 along the thickness direction and the inner surface 1041 of the bezel 104 (i.e., Figure 9 The gap p) is less than a first threshold. The first threshold is a pre-set distance threshold, such as 0.1mm, 0.15mm, or 0.2mm. Therefore, by making the gap p less than the first threshold, the gap can be minimized and optimized, improving space utilization and enhancing the overall aesthetic appeal.

[0088] Another possible implementation method is to combine Figure 9 The backlight module 20 includes a second extension 204, which includes a first side 2041 and a second side 2042. The distance between the second extension 204 and the second side 2042 in the first direction is S, that is, the distance between the first side 2041 and the second side 2042 in the first direction is S. The middle frame 10 includes a border 104, the first side 2041 is disposed opposite to the inner surface 1041 of the border 104, and the second side 2042 is disposed opposite to the inner surface 1041 of the border 104. The edge of the screen module 30 along the thickness direction (i.e., the second direction) is located between the first side 2041 and the inner surface 1041 of the border 104.

[0089] In one possible implementation, the screen module 30 is rectangular, and includes a first long side (i.e., long side BD), a second long side (i.e., long side CE), a first wide side (i.e., wide side BC), and a second wide side (i.e., wide side DE). The backlight module 20 has two second positioning portions (i.e., second positioning portions 201a and 201b) and two second fixing portions (i.e., second fixing portions 202a and 202b) along the first long side direction (i.e., the long side BD direction), and two second positioning portions (i.e., second positioning portions 201c and 201d) and two second fixing portions (i.e., second fixing portions 202c and 202d) along the second long side direction (i.e., the long side CE direction). The backlight module 20 has two second positioning parts (i.e., second positioning part 201e and second positioning part 201f) and two second fixing parts (i.e., second fixing part 202e and second fixing part 202f) along the first wide side direction (i.e., wide side BC direction), and two second positioning parts (i.e., second positioning part 201g and second positioning part 201h) and two second fixing parts (i.e., second fixing part 202g and second fixing part 202h) along the second wide side direction (i.e., wide side DE direction).

[0090] Accordingly, the middle frame 10 has two first positioning parts and two first fixing parts along the first long side direction (i.e., the long side BD direction), and the middle frame 10 has two first positioning parts and two first fixing parts along the second long side direction (i.e., the long side CE direction). The middle frame 10 has two first positioning parts and two first fixing parts along the first wide side direction (i.e., the wide side BC direction), and the middle frame 10 has two first positioning parts and two first fixing parts along the second wide side direction (i.e., the wide side DE direction).

[0091] Optionally, the above description is based on the example of the backlight module 20 including 8 second positioning parts. In actual implementation, the backlight module may include fewer second positioning parts (such as 1, 4, or 6, etc.) or more second positioning parts (such as 10, 12, or 16, etc.), which does not constitute a limitation on this solution. However, these second positioning parts still need to meet the position setting conditions of the second positioning parts, that is, the position setting conditions of the aforementioned first positioning parts.

[0092] Similarly, the above description uses the example of a backlight module 20 including 8 second fixing parts. In actual implementation, the backlight module may include fewer second fixing parts (such as 1, 4, or 6, etc.) or more second fixing parts (such as 10, 12, or 16, etc.), which does not constitute a limitation on this solution. However, these second fixing parts still need to meet the position setting conditions of the second fixing parts, that is, the position setting conditions of the first fixing parts mentioned above.

[0093] Optionally, the second positioning portion of the backlight module 20 disposed along the first long side direction and the second positioning portion of the backlight module 20 disposed along the second long side direction are symmetrically distributed along the centerline of the long side direction of the screen module 30.

Or similarly, the two second positioning portions of the backlight module 20, arranged along the second wide side direction, are symmetrically distributed along the centerline of the long side direction of the screen module 30.
