[0056] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0057] With the booming development of domestic car brands, new structures and configurations are increasingly appearing in automobiles. Among these, the audio-visual entertainment needs of rear passengers are becoming more prominent. Consequently, more models are considering the inclusion of ceiling-mounted screens from the initial project stages. Achieving high precision in the ceiling-mounted screen assembly components and matching them with the overall vehicle precision requirements is of paramount importance. Good assembly precision can enhance the user's viewing experience, improve vehicle comfort, and elevate the brand's premium image.

[0058] In related technologies, ceiling-mounted screen devices include a mounting plate connected to a vehicle frame, a display assembly, and decorative parts. The display assembly is mounted on the mounting plate, and the decorative parts are mounted on the vehicle frame or roof. The decorative parts have display windows that avoid obstructing the display screen in the display assembly. However, because the decorative parts are mounted on the vehicle frame or roof, installation is inconvenient and affects the assembly accuracy between the decorative parts and the display assembly.

[0059] To address the aforementioned technical issues, this application provides a ceiling-mounted screen device, a vehicle, and an assembly mounting fixture. In this solution, the ceiling-mounted screen device includes a mounting plate, a display screen assembly, and decorative components. The mounting plate is mounted on the vehicle frame and has multiple positioning slots. The display screen assembly is mounted on the mounting plate, with the multiple positioning slots surrounding its outer side. The decorative component has multiple first positioning members, each corresponding one-to-one with a portion of the positioning slots, and is inserted into the corresponding positioning slot. The decorative component also has snap-fit ​​members inserted into another portion of the corresponding positioning slots. The multiple positioning slots on the mounting plate surround the outer side of the display screen assembly, forming precise physical limits. The first positioning component and snap-fit ​​component of the decorative part, through their cooperation with the positioning groove, achieve precise alignment between the decorative part and the display assembly, avoiding the cumulative errors caused by the direct installation of the decorative part on the frame or roof. The decorative part is connected to the mounting plate through the combination of the first positioning component and snap-fit ​​component, which not only ensures the stable connection between the decorative part and the mounting plate, but also reduces the assembly difficulty through step assembly, reduces the impact of human operation on accuracy, simplifies the installation steps, and thus improves the assembly accuracy between the decorative part and the display assembly.

[0060] It should be noted that, Figures 1 to 14 This diagram illustrates a simplified representation of the components in the ceiling-mounted screen device, vehicle, and assembly mounting fixture. The specific structures of the remaining components in the ceiling-mounted screen device, vehicle, and assembly mounting fixture are not limited to these examples. Figures 1 to 14 of examples.

[0061] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0062] Reference Figures 1 to 6 As shown in the figure, a ceiling-mounted screen device provided in this application embodiment includes a mounting plate 100, a display screen assembly 200, and a decorative component 300.

[0063] Mounting plate 100 is used to be mounted on the frame of vehicle 10. Here, mounting plate 100 can be connected to the frame by bolts or by welding.

[0064] Mounting plate 100 has multiple positioning slots 101; display assembly 200 is mounted on mounting plate 100, and multiple positioning slots 101 are arranged around the outside of display assembly 200; display assembly 200 is bolted to mounting plate 100 to facilitate maintenance or replacement of display assembly 200 and mounting plate 100.

[0065] The decorative component 300 has multiple first positioning components 400, each corresponding to a portion of the positioning grooves 101. The first positioning component 400 is inserted into the corresponding positioning groove 101. The first positioning component 400 can be plate-shaped, with protrusions on its outer sidewall. By providing protrusions on the first positioning component 400, it is possible to ensure that the first positioning component 400 abuts tightly against the inner sidewall of the positioning groove 101 after being inserted into it, thereby increasing the friction between the first positioning component 400 and the positioning groove 101 and preventing the first positioning component 400 from dislodging from the positioning groove 101 due to shaking or vibration.

[0066] The decorative part 300 also has a snap-fit ​​part 500, which is inserted into a corresponding positioning groove 101 in another part.

[0067] By setting a first positioning element 400 on the decorative part 300, it can quickly position the decorative part 300 during installation. Then, through the cooperation of the snap-fit ​​element 500 and the positioning groove 101, the decorative part 300 is installed on the mounting plate 100. Multiple positioning grooves 101 on the mounting plate 100 surround the outside of the display assembly 200, forming precise physical limits. The first positioning element 400 and the snap-fit ​​element 500 of the decorative part 300, through their cooperation with the positioning groove 101, achieve precise alignment between the decorative part 300 and the display assembly 200, avoiding the cumulative errors caused by the direct installation of the decorative part 300 on the frame or roof. The combination of the first positioning element 400 and the snap-fit ​​element 500 to connect the decorative part 300 to the mounting plate 100 ensures a stable connection between the decorative part 300 and the mounting plate 100, and reduces assembly difficulty through step-by-step assembly, reduces the impact of human operation on accuracy, simplifies the installation steps, and thus improves the assembly accuracy between the decorative part 300 and the display assembly 200.

[0068] Reference Figure 5 and Figure 6 As shown, in one possible implementation, the snap-fit ​​member 500 includes two connecting plates 510 and a snap-fit ​​protrusion 520 disposed between the two connecting plates 510.

[0069] The first end of the connecting plate 510 is connected to the decorative part 300, and the second end of the connecting plate 510 is connected to the snap-fit ​​protrusion 520. The snap-fit ​​protrusion 520 protrudes towards the side away from the decorative part 300 and is inserted into the corresponding positioning groove 101.

[0070] In the above embodiment, the snap-fit ​​component 500 consists of two connecting plates 510 and a snap-fit ​​protrusion 520 in the middle, forming a "bridge-like" structure. The first end of the connecting plate 510 is fixed to the decorative component 300, and the second end is connected to the snap-fit ​​protrusion 520, which is inserted into the positioning groove 101 of the mounting plate 100. By setting two connecting plates 510, the force on the snap-fit ​​protrusion 520 can be distributed, avoiding single-point stress concentration and enhancing the tensile and torsional resistance of the connection between the decorative component 300 and the mounting plate 100. In other possible implementations, the projection of the snap-fit ​​protrusion 520 toward the connecting plate 510 is located inside the connecting plate 510. This is equivalent to the width of the connecting plate 510 being greater than the width of the snap-fit ​​protrusion 520. When the snap-fit ​​protrusion 520 is inserted into the positioning groove 101, the connecting plate 510 has a certain limiting effect, preventing the snap-fit ​​protrusion 520 from moving too far.

[0071] In one possible implementation, the snap-fit ​​protrusion 520 includes a body 521 and an elastic element 522, with the body 521 connecting two connecting plates 510.

[0072] The elastic element 522 is disposed on the main body 521. The elastic element 522 is configured such that when the snap-fit ​​protrusion 520 is inserted into the corresponding positioning groove 101, the elastic element 522 abuts tightly against the inner wall of the positioning groove 101.

[0073] In the above embodiment, by providing an elastic element 522 in the snap-fit ​​protrusion 520, when the snap-fit ​​protrusion 520 is inserted into the positioning groove 101 of the mounting plate 100, the elastic element 522 will generate a restoring force due to deformation, so that the snap-fit ​​protrusion 520 and the inner wall of the positioning groove 101 form a tight abutment. This effectively prevents the decorative part 300 from loosening due to vehicle vibration or external impact, ensuring the stability of the connection between the decorative part 300 and the mounting plate 100. In addition, the elasticity of the elastic element 522 can compensate for minor dimensional deviations during manufacturing or assembly, avoiding wobbling caused by excessive gaps, thereby improving the overall assembly accuracy. The elastic function of the elastic element 522 allows the snap-fit ​​protrusion 520 to be automatically fixed after being inserted into the positioning groove 101, without the need for additional tightening operations, reducing assembly complexity and improving production efficiency. The tight contact between the elastic element 522 and the inner wall of the positioning groove 101 forms a physical limit, preventing the decorative part 300 from accidentally falling off during use, enhancing the reliability of the product.

[0074] In addition, the elastic element 522 can undergo elastic deformation under the vibration environment of the vehicle 10 in motion, absorbing part of the impact force and reducing the vibration energy transmitted to the display assembly 200 or the trim piece 300, thereby protecting the internal components and extending their service life. The buffering effect of the elastic element 522 can reduce the rigid collision between the trim piece 300 and the mounting plate 100, reduce abnormal noise caused by vibration, and improve the quietness of the vehicle interior.

[0075] In one possible implementation, the elastic member 522 includes a connecting portion 5221, a first elastic portion 5222, and a second elastic portion 5223, with the connecting portion 5221 connecting between the first elastic portion 5222 and the second elastic portion 5223. The first elastic portion 5222 and the second elastic portion 5223 may be elastic metal sheets.

[0076] The first elastic part 5222 and the second elastic part 5223 have a clamping force that moves closer to each other. The first elastic part 5222 and the second elastic part 5223 are located on both sides of the main body 521 and are clamped and fixed to the main body 521.

[0077] In the above embodiment, the first elastic portion 5222 and the second elastic portion 5223 are located on both sides of the main body 521, and the main body 521 is fixed by the clamping force of their proximity. The clamping forces of the first elastic portion 5222 and the second elastic portion 5223 on both sides of the main body 521 form a symmetrical constraint to prevent loosening caused by vehicle 10 vibration or external impact. The connecting portion 5221 balances the forces of the first elastic portion 5222 and the second elastic portion 5223 on both sides, avoids stress concentration, and extends the life of the elastic element 522.

[0078] In practice, the elastic element 522 is an integrated module, with the first elastic part 5222 and the second elastic part 5223 integrated through the connecting part 5221. As a pre-assembled module, the elastic element 522 can be directly combined with the snap-fit ​​protrusion 520, reducing the number of parts and assembly steps, and lowering production costs. If the elastic element 522 is damaged, the module can be replaced separately without disassembling the entire snap-fit ​​structure, improving maintenance efficiency.

[0079] In one possible implementation, the number of first elastic portions 5222 is set to multiple, the multiple first elastic portions 5222 are arranged sequentially at intervals, and the arrangement direction of the multiple first elastic portions 5222 is parallel to the arrangement direction of the two connecting plates 510.

[0080] The number of second elastic parts 5223 is set to multiple, and the multiple second elastic parts 5223 are arranged at intervals in sequence, and the arrangement direction of the multiple second elastic parts 5223 is parallel to the arrangement direction of the two connecting plates 510.

[0081] In the above embodiments, by providing multiple first elastic portions 5222 and multiple second elastic portions 5223, the pressure of the inner wall of the positioning groove 101 on the elastic member 522 can be dispersed, avoiding local stress concentration and reducing fatigue deformation of the elastic member 522 caused by long-term pressure. The spaced-apart first elastic portions 5222 and second elastic portions 5223 can fit more tightly against the inner wall of the positioning groove 101, further improving connection stability.

[0082] Furthermore, by providing multiple first elastic parts 5222 and multiple second elastic parts 5223, the ability of the elastic element 522 to adaptively fit the positioning groove 101 can be enhanced, assembly accuracy can be improved, and the installation process can be simplified.

[0083] In one possible implementation, the decorative element 300 also has a snap hook (not shown in the figure), and the mounting plate 100 has a snap groove (not shown in the figure), in which the snap hook is hooked.

[0084] In the above embodiments, by providing snap-fit ​​hooks on the decorative element 300, the decorative element 300 can be pre-positioned through the snap-fit ​​hooks and snap-fit ​​grooves during installation, preventing the decorative element 300 from shaking violently relative to the mounting plate 100. Then, the decorative element 300 is fixed by the first positioning element 400 and the snap-fit ​​element 500, further simplifying the assembly steps and helping to improve the stability when assembling the decorative element 300.

[0085] In one possible implementation, the decorative element 300 has a display window 301 for displaying the display screen of the display assembly 200.

[0086] Multiple first positioning elements 400 are evenly distributed around the display window 301.

[0087] The first positioning elements 400 are evenly distributed around the display window 301, ensuring symmetry at the connection points between the decorative element 300 and the mounting plate 100. This prevents the decorative element 300 from shifting due to uneven stress, thus guaranteeing strict alignment between the display window 301 and the display screen. The evenly distributed first positioning elements 400 can be simultaneously inserted into the corresponding positioning slots 101 during installation, forming multi-directional constraints, reducing the impact of manual operation on assembly accuracy, and preventing display area shifting or tilting. The evenly distributed first positioning elements 400 ensure uniform stress distribution on the decorative element 300, preventing excessive local stress that could lead to deformation or loosening. Especially under the vibration environment of the vehicle 10, this effectively maintains the stability of the decorative element 300.

[0088] This application also provides a vehicle 10, including a vehicle body and the aforementioned ceiling-mounted screen device. The ceiling-mounted screen device is disposed in the vehicle body. Those skilled in the art will understand that the ceiling-mounted screen device can be disposed within the vehicle's roof. The ceiling-mounted screen device has been described above and will not be repeated here. By providing the aforementioned ceiling-mounted screen device in the vehicle 10, the assembly precision of the ceiling-mounted screen device can be improved, enhancing the user experience of the vehicle 10. The vehicle 10 in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Of course, it can also be other electrical equipment; this application does not limit this.

[0089] Reference Figures 7 to 11 As shown, and in combination Figures 1 to 6 In one possible implementation, this application also provides an assembly mounting fixture 600, including a support plate 610 and a clamping mechanism 620.

[0090] The support plate 610 has a plurality of second positioning members 611, which are used to be inserted into the positioning grooves 101 on the mounting plate 100 corresponding to the first positioning member 400. It is understood that the support plate 610 is mounted on the mounting plate 100 through the second positioning members 611 and shares the same positioning groove 101 with the decorative member 300.

[0091] A clamping mechanism 620 is disposed on the support plate 610 and is used to clamp the display assembly 200.

[0092] In the above embodiment, the operator can first clamp the display assembly 200 onto the support plate 610 using the clamping mechanism 620, and then use the second positioning member 611 inserted into the positioning groove 101 to achieve the positioning and installation of the support plate 610. At this time, the display assembly 200 is tightened with the mounting plate 100 to fix the display assembly 200 onto the mounting plate 100. Then, the clamping mechanism 620 is operated to disengage the display assembly 200 from the support plate 610, and then the assembly mounting fixture 600 is removed.

[0093] Here, the display assembly 200 is installed using the assembly mounting fixture 600. The second positioning member 611 of the support plate 610 and the first positioning member 400 of the decorative part 300 share the same set of positioning grooves 101 on the mounting plate 100, ensuring that the mounting reference of the support plate 610 and the decorative part 300 are completely consistent, avoiding assembly deviations caused by positioning differences. Through the precise cooperation between the second positioning member 611 and the positioning groove 101, the support plate 610 can be quickly positioned to the correct position on the mounting plate 100, providing a stable mounting reference for the display assembly 200 and ensuring strict alignment between the display and the decorative part 300.

[0094] In addition, the support plate 610 evenly supports the weight of the display assembly 200 through multiple second positioning elements 611, avoiding excessive local stress that could lead to deformation or damage. The decorative element 300 shares the positioning groove 101 with the support plate 610, reducing the design complexity and mold opening cost of the mounting plate 100.

[0095] In one possible implementation, the support plate 610 also has a plurality of support columns 612, one end of which is away from the support plate 610 and is used to abut against the mounting plate 100.

[0096] During the installation of the display assembly 200, the support columns 612 are evenly distributed on the bottom of the support plate 610, directly abutting against the mounting plate 100 to form a multi-point support structure. This disperses the weight pressure of the display assembly 200, preventing deformation or twisting of the support plate 610 due to excessive local stress. The rigid contact of the support columns 612 fills any small gaps or unevenness between the support plate 610 and the mounting plate 100, reducing assembly stress through physical limiting and ensuring a tighter fit between the support plate 610 and the mounting plate 100, thus improving the overall structural stability. The end face of the support column 612 directly abuts against the mounting plate 100, eliminating the need for additional fixing components (such as screws) to achieve pre-positioning of the support plate 610. By observing the contact between the support column 612 and the mounting plate 100, operators can quickly determine whether the support plate 610 is level, thereby adjusting the installation posture of the display assembly 200 and shortening calibration time.

[0097] In addition, the height and distribution of the support columns 612 can be flexibly adjusted according to the position of the positioning slots 101 of the mounting plate 100, so that the same tooling can be adapted to various vehicle models or different sizes of display screen assemblies 200, reducing development costs.

[0098] In one possible implementation, the clamping mechanism 620 includes a reference base 621 and an adjusting member 622 disposed on the support plate 610.

[0099] The reference base 621 and the adjustment component 622 are respectively located on opposite sides of the display assembly 200.

[0100] The adjusting member 622 has a movable end 6221, which can move toward or away from the base 621 to fix or detach the display assembly 200 from the support plate 610.

[0101] The reference base 621 serves as a fixed reference point to ensure the positional accuracy of the display assembly 200 on the support plate 610. It cooperates with the adjusting member 622 to form a symmetrical clamping. The adjusting member 622 and the reference base 621 are located on both sides of the display. The movement of the movable end 6221 applies a uniform clamping force to prevent the display from deforming or being damaged due to local stress concentration.

[0102] The movable end 6221 of the adjusting member 622 can move toward or away from the reference base 621. In this embodiment, the movable end 6221 of the adjusting member 622 is controlled by the knob 6222 to achieve quick clamping or release of the display assembly 200. This can be completed with just one hand, significantly improving assembly efficiency on the production line. The relative position of the reference base 621 and the adjusting member 622 can be adjusted according to different display sizes or models. The assembly mounting fixture 600 has high reusability, reducing repetitive development costs caused by product iterations.

[0103] In one specific implementation, at least two clamping mechanisms 620 are provided, with clamping mechanisms 620 arranged in both the lateral and longitudinal directions of the support plate 610, the lateral direction being perpendicular to the longitudinal direction. Thus, by providing at least two clamping mechanisms 620, the display assembly 200 can be subjected to the clamping force of the adjusting member 622 in both the lateral and longitudinal directions, making the display assembly 200 more stable when mounted on the support plate 610.

[0104] In addition, the linkage between the base 621 and the adjustment member 622 ensures that the display assembly 200 can only be removed when all the adjustment members 622 are fully unlocked, avoiding the risk of forced disassembly due to incomplete unlocking and protecting the structure.

[0105] In one specific implementation, a handle 613 is provided on the side of the support plate 610 away from the clamping mechanism 620. The operator can move or flip the support plate 610 through the handle 613 to facilitate the operation of the clamping mechanism 620 and to facilitate the installation of the display assembly 200.

[0106] The support plate 610 is also provided with an observation window 6101, which is used to display part of the display assembly 200. On the one hand, the staff can observe the positioning and connection between the display assembly 200 and the mounting plate 100 through the observation window 6101. On the other hand, by setting the observation window 6101, it helps to reduce the weight of the assembly installation fixture 600 and facilitates the operation of the staff.

[0107] Reference Figure 12 , Figure 13 and Figure 14 As shown, and in combination Figures 1 to 11 This application also provides a handheld inspection tool 700, which includes a structural frame 710. The structural frame 710 is provided with a plurality of third positioning members 720. The third positioning members 720 are used to be inserted into positioning slots 101 on the mounting plate 100 corresponding to the first positioning members 400. It is understood that the structural frame 710 is mounted on the mounting plate 100 via the third positioning members 720, and shares the same positioning slot 101 with the decorative member 300. The structural frame 710 is provided with a detection slot 7101, which is used to display the screen of the display assembly 200.

[0108] After installing the display assembly 200 onto the mounting plate 100, the operator disassembles the assembly mounting fixture 600. Then, through the cooperation of the third positioning component 720 and the positioning groove 101, the handheld inspection tool 700 is installed. The display screen is located within the inspection groove 7101. It can be understood that at this point, the handheld inspection tool 700 is equivalent to a standard part of the decorative component 300. At this time, the assembly tolerances between the handheld inspection tool 700 and the display assembly 200, such as surface flatness and shape contour, can be measured. The third positioning component 720 of the support frame 710 and the first positioning component 400 of the decorative component 300 share the same set of positioning grooves 101 on the mounting plate 100, ensuring that the installation datum of the support frame 710 and the decorative component 300 are completely consistent, avoiding assembly deviations caused by positioning differences.

[0109] The implementation principle of a ceiling-mounted screen device, a vehicle 10, and an assembly mounting fixture 600 according to an embodiment of this application is as follows: The ceiling-mounted screen device includes a mounting plate 100, a display screen assembly 200, and a decorative component 300. The mounting plate 100 is used to mount on the frame of the vehicle 10 and has multiple positioning slots 101. The display screen assembly 200 is mounted on the mounting plate 100, and the multiple positioning slots 101 are arranged around the outside of the display screen assembly 200. The decorative component 300 has multiple first positioning elements 400, each of which corresponds one-to-one with a portion of the positioning slots 101 and is inserted into the corresponding positioning slot 101. The decorative component 300 also has a snap-fit ​​element 500, which is inserted into another portion of the corresponding positioning slots 101. The multiple positioning slots 101 on the mounting plate 100 surround the outside of the display screen assembly 200, forming precise physical limits. The first positioning member 400 and the snap-fit ​​member 500 of the decorative part 300, through their cooperation with the positioning groove 101, achieve precise alignment between the decorative part 300 and the display assembly 200, avoiding the cumulative error caused by the direct installation of the decorative part 300 on the vehicle frame or roof. The decorative part 300 is connected to the mounting plate 100 through the combination of the first positioning member 400 and the snap-fit ​​member 500, which not only ensures the stable connection between the decorative part 300 and the mounting plate 100, but also reduces the assembly difficulty through step-by-step assembly, reduces the impact of human operation on accuracy, simplifies the installation steps, and thus improves the assembly accuracy between the decorative part 300 and the display assembly 200.
