Description

Technical Field

[0001] This application relates to the automotive field, and in particular to a roof structure. Background Technology

[0002] Entertainment features have become a key selling point for expanding automotive functionality. With the widespread adoption of electronics, more and more cars are using large screens in the front seats. This is because the front seats, which originally had fixed structures like the dashboard, now allow for the installation of large screens, multiple screens, or even mobile screens. In daily life, passengers, especially the elderly and minors, mostly sit in the back seats. The rear seats offer more space, and when the vehicle is stationary, the driver also needs to rest and enjoy entertainment with multiple passengers in the back. Therefore, the demand for rear-seat entertainment systems is very high.

[0003] Thanks to their small size, high resolution, and internet connectivity, ceiling-mounted screens are increasingly being installed in cars, especially MPVs. These screens are typically located behind the front seats, between the left and right B-pillars, for the convenience of rear passengers.

[0004] To add a ceiling-mounted screen to the existing roof structure, a special roof beam needs to be developed, and there are specific requirements for the position and structure of the roof beam, which will increase development costs and vehicle weight. At the same time, since the ceiling-mounted screen bracket is held on the roof beam by connectors and pads, the ceiling-mounted screen bracket cannot be accurately positioned in the front-back and left-right directions, which will affect the installation accuracy of the ceiling-mounted screen on the vehicle body.

[0039] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0040] This application provides a roof structure that solves the problem in related technologies where setting a roof beam to fix the ceiling screen increases development costs and vehicle weight, and also fails to guarantee the installation accuracy of the ceiling screen on the vehicle body.

[0041] See Figures 1 to 19This application provides a vehicle roof structure, including: a roof assembly, a ceiling-mounted screen assembly, and a canopy 7. The roof assembly has a ceiling-mounted screen mounting area, and the ceiling-mounted screen mounting area has a plurality of first positioning members. The ceiling-mounted screen assembly is located at the bottom of the roof assembly and at the ceiling-mounted screen mounting area. The ceiling-mounted screen assembly has a plurality of second positioning members, and the plurality of second positioning members and the plurality of first positioning members are connected in a one-to-one correspondence. The canopy 7 is fixed to the bottom of the roof assembly, and the canopy 7 has an installation groove for the ceiling-mounted screen assembly to pass through. The canopy 7 is connected to the ceiling-mounted screen assembly.

[0042] In this application, there is no need to develop an additional top cover beam. A ceiling screen assembly is set between the top cover assembly and the ceiling 7. The installation slot can be used to initially locate the installation position of the ceiling screen assembly. At the same time, multiple first positioning parts are set on the ceiling screen installation area, so that multiple second positioning parts set on the ceiling screen assembly are connected one-to-one with the first positioning parts, ensuring the installation accuracy of the ceiling screen assembly on the top cover assembly.

[0043] The roof outer panel 1 is further provided with a front sunroof mounting area and a rear sunroof mounting area, with the ceiling-mounted screen mounting area located between the front and rear sunroof mounting areas. It should be noted that the roof structure of this application is applicable to vehicles equipped with a front sunroof body 8 and a rear sunroof body 9, as well as vehicles not equipped with these two bodies. That is, this application is applicable to vehicles with steel roofs or glass roofs featuring reinforcing rings or roof crossbeams.

[0044] When the front sunroof body 8 and the rear sunroof body 9 are installed, through slots need to be opened in the front sunroof installation area and the rear sunroof installation area. When the front sunroof body 8 and the rear sunroof body 9 are not installed, the plates in the front sunroof installation area and the rear sunroof installation area are retained.

[0045] To accommodate different vehicle models, the roof 7 is located below the front sunroof installation area and the rear sunroof installation area, and a passage hole is opened in the sunroof light transmission area. In models equipped with the front sunroof body 8 and the rear sunroof body 9, sunlight can enter the vehicle through the passage hole. In models not equipped with the front sunroof body 8 and the rear sunroof body 9, the passage hole enables the roof structure to be lightweight and reduces material manufacturing costs.

[0046] The following explanation uses a model equipped with a front sunroof body 8 and a rear sunroof body 9 as an example:

[0047] Based on the above embodiments, in this embodiment, the roof structure further includes: a front sunroof body 8 and a rear sunroof body 9, wherein the front sunroof body 8 is disposed in the front sunroof mounting area on the outer panel 1 of the roof; and the rear sunroof body 9 is disposed in the rear sunroof mounting area on the outer panel 1 of the roof.

[0048] Through slots will be made at the front sunroof mounting area and the rear sunroof mounting area. In this embodiment, the front sunroof body 8 can be configured as an operable sunroof, and the front sunroof body 8 is mounted on the top cover assembly from bottom to top in the final assembly. The glass of the front sunroof body 8 is accommodated in the front opening of the top cover assembly. The glass top of the rear sunroof body 9 is installed from top to bottom and is bonded to the top of the rear opening of the top cover assembly with glass adhesive.

[0049] Based on the above embodiments, in this embodiment, the top cover assembly includes: a top cover outer plate 1 and a reinforcing ring, the reinforcing ring is disposed at the bottom end of the top cover outer plate 1, and the ceiling screen mounting area is disposed on the reinforcing ring, and the ceiling screen assembly is fixed to the bottom end of the reinforcing ring.

[0050] The embodiments described in this application present a steel roof structure. If a glass roof structure is used, the technical solution of this application can still be used.

[0051] The reinforcing rings include a front sunroof reinforcing ring 2 and a rear sunroof reinforcing ring 3. (See also...) Figure 3 As shown, the front sunroof reinforcing ring 2 and the rear sunroof reinforcing ring 3 can be annular structures, that is, the front sunroof reinforcing ring 2 is provided with a through groove for the front sunroof body 8 to pass through, and the rear sunroof reinforcing ring 3 is provided with a through groove for the rear sunroof body 9 to pass through; alternatively, depending on the fixing requirements of the front sunroof body 8 and the rear sunroof body 9, they can be designed as flat plate structures without holes in the middle. This is suitable for models that are not equipped with front sunroof body 8 and rear sunroof body 9. See also Figure 5 As shown, the sunroof body 8 has multiple holes such as the first mounting through hole 801 and the second mounting through hole 802, and is installed from bottom to top below the sunroof reinforcing ring 2.

[0052] To provide support for the outer roof panel 1 via the front sunroof reinforcing ring 2 and the rear sunroof reinforcing ring 3, thereby improving the rigidity and modal characteristics of the outer roof panel 1 and preventing it from generating a rumbling sound inside the vehicle body when hit by rain, hail, or other objects, an anti-interference gap is provided between the front sunroof reinforcing ring 2 and the rear sunroof reinforcing ring 3. In this application, the front sunroof reinforcing ring 2 and the rear sunroof reinforcing ring 3 retain only an anti-interference gap of about 5mm in the front-rear direction. Furthermore, depending on the number of sunroofs or whether a panoramic glass roof is used, the front sunroof reinforcing ring 2 and the rear sunroof reinforcing ring 3 can also be combined into a single crossbeam structure.

[0053] Furthermore, a rear sunroof sunshade 10 is installed on the rear sunroof reinforcing ring 3. The rear sunroof sunshade 10 is installed on the outer panel 1 of the roof from bottom to top. For details, see [link to relevant documentation]. Figure 5 As shown, the rear sunroof sunshade 10 has multiple holes, such as the sunshade installation passage hole 1001, and is installed from bottom to top below the rear sunroof reinforcing ring 3.

[0054] Based on the above embodiments, in this embodiment, the first positioning component is disposed on the rear sunroof reinforcing ring 3, the front sunroof reinforcing ring 2 is provided with a plurality of first mounting components, and the ceiling screen assembly is also provided with a plurality of second mounting components, with the plurality of second mounting components corresponding one-to-one with the plurality of first mounting components.

[0055] Specifically, in this application, the first positioning component is a second welding nut 302, and the first mounting component is a first welding nut 203. Multiple first welding nuts 203 for fixing the ceiling screen assembly are provided on the front sunroof reinforcing ring 2, and multiple second welding nuts 302 for fixing the ceiling screen assembly are also provided on the rear sunroof reinforcing ring 3. Furthermore, the positional accuracy of the second welding nut 302 is higher than that of the first welding nut 203. In this application, the second welding nut 302 is selected as the assembly positioning reference hole for the ceiling screen assembly.

[0056] Based on the above embodiments, in this embodiment, the bottom end of the outer top cover plate 1 is provided with a first flange structure, and the front sunroof reinforcing ring 2 is provided with a second flange structure, and the first flange structure and the second flange structure are fitted and fixed together.

[0057] Specifically, in this embodiment, the outer panel 1 of the top cover has a downward-facing first flange structure around the glass of the sunroof body 8. The function of the first flange structure is to cooperate with the openable sunroof sealing strip to achieve opening, closing, and sealing. See also Figure 4 As shown, the first flange structure includes a first rear flange 101 and a first side flange 102. Corresponding to the first flange structure of the roof outer panel 1, a second flange structure is provided on the front sunroof reinforcing ring 2. The second flange structure includes a second rear flange 201 and a second side flange 202. The first rear flange 101 and the second rear flange 201 are attached and connected by spot welding or arc welding, and the first side flange 102 and the second side flange 202 are attached and connected by spot welding or arc welding. That is, the roof outer panel 1 and the front sunroof reinforcing ring 2 are forcibly connected in both the front-rear and left-right directions. Through welding methods such as spot welding or arc welding, the connection between the two is more solid and less prone to loosening or deformation, thereby improving the stability of the entire structure and further enhancing the torsional resistance of the vehicle body, making the vehicle more stable and safer during driving. The attachment and welding of the first flange structure and the second flange structure form a tight sealing structure, effectively preventing the intrusion of external substances such as rainwater and dust.

[0058] Furthermore, the bottom end of the outer panel 1 of the top cover is provided with a first step surface 103, and the rear sunroof reinforcing ring 3 is provided with a second step surface 301, and the first step surface 103 and the second step surface 301 are fixed together.

[0059] Specifically, the outer roof panel 1 has a first stepped surface 103 around the rear sunroof reinforcing ring 3. The first stepped surface 103 is used to adhere the rear sunroof reinforcing ring 3 to the roof using adhesive. The rear sunroof reinforcing ring 3 also has a second stepped surface 301, and the first stepped surface 103 and the second stepped surface 301 are forcibly joined and welded together in the vertical direction of the vehicle body. The stepped surface design increases the contact area between the outer roof panel 1 and the rear sunroof reinforcing ring 3, thereby improving the connection strength between the two. This strong connection method of welding further enhances the stability of the entire roof structure and ensures the safety of the vehicle during driving.

[0060] Furthermore, the distance between the front sunroof reinforcing ring 2 and the rear sunroof reinforcing ring 3 in both the front-rear and vertical directions is controlled to be approximately 5mm. Additionally, the first flange structure of the outer roof panel 1 around the glass of the front sunroof body 8 is affected by the positional deviation of the flange surfaces of their respective stamped parts, resulting in a deviation of approximately ±1mm in both the front-rear and horizontal directions for the front sunroof reinforcing ring 2. The rear sunroof reinforcing ring 3 and the outer roof panel 1 are positioned relative to each other using welded locating pins, ensuring that the positional accuracy of the rear sunroof reinforcing ring 3 is controlled within ±0.75mm.

[0061] Based on the above embodiments, in this embodiment, the ceiling screen assembly includes: a ceiling screen bracket 4, a ceiling screen body 5, and a ceiling screen decorative cover 6. The ceiling screen bracket 4 is disposed at the bottom end of the top cover assembly, and the second positioning member is disposed on the ceiling screen bracket 4. The ceiling screen body 5 is connected to the ceiling screen bracket 4 and has an installation groove. The ceiling screen decorative cover 6 is disposed at the bottom end of the ceiling screen body 5. The ceiling screen decorative cover 6 is connected to the ceiling screen body 5 and the ceiling 7, and the ceiling screen decorative cover 6 is pressed onto the ceiling 7 so that the ceiling screen decorative cover 6 and the ceiling 7 have an interference in the vehicle height direction, and the ceiling screen decorative cover 6 and the ceiling 7 have a set overlap in the horizontal direction.

[0062] The ceiling-mounted screen bracket consists of approximately four parts, or the left and right parts can be combined into a single piece. Specifically:

[0063] In some embodiments, the ceiling-mounted screen bracket 4 includes a left bracket and a right bracket. The left bracket is fixed to the bottom end of the top cover assembly, and a second positioning element is provided on the left bracket. The right bracket is fixed to the bottom end of the top cover assembly, and a second positioning element is also provided on the right bracket.

[0064] In the embodiments of this application, the ceiling screen bracket 4 includes a left bracket and a right bracket. Taking the right bracket as an example, the bracket is a sheet metal stamping part with a horizontal bottom surface and four horizontal legs. The four legs are respectively provided with a first mounting hole 401, a second mounting hole 402, a third mounting hole 403 and a fourth mounting hole 404.

[0065] Furthermore, the first mounting hole 401 is a circular hole, and its diameter is determined by the diameter of the bracket fixing bolt 11. If the diameter of the bracket fixing bolt 11 is D1, the diameter of the first mounting hole 401 can be D1 + 0.2 mm. Figure 7 The second mounting hole 402 shown is an oblong hole, the width of its shorter side being the same as the diameter of the first mounting hole 401, and the center line connecting the centers of the longer sides passing through the center of the first mounting hole 401. The recommended length of the oblong hole is D1 + 4.2 mm. That is, the first mounting hole 401 and the second mounting hole 402 can form a set of positioning holes. The third mounting hole 403 and the fourth mounting hole 404 are circular holes, with a recommended diameter of D1 + 3 mm.

[0066] More specifically, such as Figure 4 , Figure 6 and Figure 7 As shown, the first mounting hole 401 and the second mounting hole 402 correspond to the second welded nut 302 in the rear sunroof reinforcing ring 3. That is, in this embodiment, the second mounting component is set as the first mounting hole 401 and the second mounting hole 402. The right bracket can be connected to the top cover assembly from bottom to top using the bracket fixing bolt 11. The first mounting hole 401 and the second mounting hole 402 are both mounting holes and positioning holes, thereby defining the front-rear position and left-right position of the right bracket and the rear sunroof reinforcing ring 3. The third mounting hole 403 and the fourth mounting hole 404 correspond to the first welded nut 203, and the right bracket is connected to the front sunroof reinforcing ring 2 from bottom to top using the ceiling screen fixing bolt 12.

[0067] The bottom surface of the right bracket also has several third welding nuts 405, a ceiling screen positioning hole 406, and a ceiling screen pre-installation hole 407. On the corresponding left bracket, the ceiling screen pre-installation hole 407 is an oblong hole.

[0068] The ceiling screen bracket 4 in this embodiment is installed as follows: First, use the bracket fixing bolt 11 in the first mounting hole 401 and the second mounting hole 402 and tighten it on the second welding nut 302 of the rear sunroof reinforcing ring 3; then screw the bracket fixing bolt 11 into the third mounting hole 403 and the fourth mounting hole 404 and tighten it.

[0069] In other embodiments, a connecting plate is connected between the left and right supports, and the left and right supports and the connecting plate are integrally formed.

[0070] In this embodiment, the ceiling-mounted screen bracket 4 is an integral structure, and... Figure 6 and Figure 7 Compared to the left and right brackets shown, this ceiling-mounted screen bracket 4 integrates both left and right brackets. This allows for the supply of a complete ceiling-mounted screen bracket 4 assembly, reducing the number of parts, but increasing the weight of the parts. In practice, the choice of structure needs to be considered comprehensively based on process assembly requirements.

[0071] Further, see Figure 8 As shown, the ceiling screen bracket 4 has a first mounting hole 401 and a second mounting hole 402 on its horizontal support legs. The diameters and relative positions of the first mounting hole 401 and the second mounting hole 402 are... Figure 6 and Figure 7 The left and right brackets shown are identical. Furthermore, both the left and right brackets are provided with mounting notches 409 for bolts to pass through. The mounting notch 409 is a U-shaped notch facing the front of the vehicle, and its width is the same as the diameter of the third mounting hole 403.

[0072] In this embodiment, using the ceiling-mounted screen bracket 4, pre-assembly of the ceiling-mounted screen bracket 4 and the top cover assembly can be achieved. The specific operation steps are as follows:

[0073] First of all Figure 4 The bracket fixing bolts 11 are screwed into the first welding nut 203 of the front sunroof reinforcing ring 2 and the second welding nut 302 inside the rear sunroof reinforcing ring 3, respectively. After screwing in, the bracket fixing bolts 11 maintain a gap of 2-5mm with the front sunroof reinforcing ring 2. Then, the ceiling screen bracket 4 is leveled, and the mounting notch 409 is inserted into the gap between the bracket fixing bolt 11 and the rear sunroof reinforcing ring 3, and into the gap between the bracket fixing bolt 11 and the front sunroof reinforcing ring 2. At this time, the ceiling screen bracket 4 can be loosened. Under its own weight, the ceiling screen bracket 4 will be supported by the bracket fixing bolts 11, thus forming a pre-installation. Next, the bracket fixing bolts 11 are used in the first mounting hole 401 and the second mounting hole 402 and tightened onto the second welding nut 302 of the rear sunroof reinforcing ring 3. Finally, the bracket fixing bolts 11 screwed into the mounting notch 409 are tightened.

[0074] The above embodiments are merely various possible implementations of the embodiments of this application, and the embodiments of this application are not limited thereto. The ceiling screen bracket 4 is fixed to the front sunroof reinforcing ring 2 and the rear sunroof reinforcing ring 3 by means of bracket fixing bolts 11. During the installation process, the ceiling screen bracket 4 is located below the front sunroof body 8, the rear sunroof body 9, and the rear sunroof sunshade 10, and a certain design gap is maintained with the above parts.

[0075] The installation order of the ceiling screen bracket 4, ceiling screen body 5, and ceiling 7 in this embodiment can be changed. The ceiling screen bracket 4 and ceiling screen body 5 can be installed first, followed by the ceiling 7. Alternatively, the ceiling 7 can be installed first, followed by the ceiling screen bracket and ceiling screen body 5. The structure of this application allows for the assembly and disassembly of the ceiling screen bracket 4 and ceiling screen body 5 without disassembling the ceiling 7. This provides convenience for after-sales maintenance, replacement, or retrofitting of the ceiling screen body 5. The ceiling screen decorative cover 6 is installed in the final step.

[0076] Based on the above embodiments, in this embodiment, the ceiling 7 includes: a base material 705, a first side reinforcement frame 702, and a second side reinforcement frame 704. The base material 705 has a mounting groove in the middle for mounting the ceiling screen assembly. The base material 705 is also provided with a front sunroof reinforcement frame 701 and a rear sunroof reinforcement frame 703. The first side reinforcement frame 702 is fixed to the bottom of the base material 705 and is located on one side of the mounting groove. The second side reinforcement frame 704 is fixed to the bottom of the base material 705 and is located on the other side of the mounting groove.

[0077] The substrate 705 is also covered with a fabric. Both the substrate 705 and the fabric are made of soft materials. The substrate 705 and the fabric have openings in the front sunroof installation area, the rear sunroof installation area, and the ceiling screen assembly. The front sunroof reinforcing frame 701, the rear sunroof reinforcing frame 703, the first side reinforcing frame 702, and the second side reinforcing frame 704 are made of lightweight materials such as fiberglass injection molded parts or aluminum plates.

[0082] See Figure 17 As shown, section AA divides the roof into left and right parts. The front sunroof reinforcing ring 2 and the rear sunroof reinforcing ring 3 both have W-shaped sections in adjacent areas, and the distance between them and L1 is more than 5mm. The gap between the front sunroof reinforcing ring 2, the rear sunroof reinforcing ring 3 and the outer roof panel 1 is more than 3mm. Shock-absorbing rubber can be used at the gap to provide modality for the outer roof panel 1. The technical solution of this application is also applicable to the merging of the front sunroof reinforcing ring 2 and the rear sunroof reinforcing ring 3, or simplified into a horizontal beam structure running through the left and right sides of the vehicle body. The ceiling-mounted screen decorative cover 6 is pressed upward onto the roof 7. To ensure a small gap between the ceiling-mounted screen decorative cover 6 and the roof 7 and improve the appearance refinement, the ceiling-mounted screen decorative cover 6 and the roof 7 have a 2mm interference in the height direction. When the ceiling-mounted screen decorative cover 6 is assembled, it will compress the roof 7 upward. Furthermore, the horizontal overlap L2 between the front sunroof reinforcing frame 701, the rear sunroof reinforcing frame 703, the first side reinforcing frame 702, the second side reinforcing frame 704, and the ceiling screen decorative cover 6 is set to 2-4mm to improve the rigidity of the ceiling 7 in the overlapping area, prevent the ceiling 7 from bending under the compression of the ceiling screen decorative cover 6, reduce the gap between the ceiling screen decorative cover 6 and the ceiling 7, and provide reaction force to the periphery of the ceiling screen decorative cover 6 to prevent the decorative cover from making abnormal noise on bumpy roads.

Figure 19 As shown, section CC divides the roof into left and right parts, and is connected by the second welded nut 302. In this section, both fixing points of the ceiling screen bracket 4 fall on the rear sunroof reinforcing ring 3. The bracket fixing bolt 11 passes through the first mounting hole 401 and the second mounting hole 402 from bottom to top, positioning and fixing the ceiling screen bracket 4 to the rear sunroof reinforcing ring 3.

[0084] In summary, the roof of this application ensures the installation accuracy of the ceiling-mounted screen, ceiling-mounted screen decorative cover 6, and ceiling-mounted screen bracket 4 on the vehicle body; the roof assembly serves as the mounting point for the ceiling-mounted screen bracket 4, and the high-precision rear sunroof reinforcing ring 3 is identified as the positioning reference for the ceiling-mounted screen bracket 4; the ceiling-mounted screen bracket 4 is provided with its own positioning holes to provide positioning holes for the ceiling-mounted screen, and the ceiling-mounted screen bracket 4 can be used as an integral bracket or a split bracket according to process requirements; the four legs of the ceiling-mounted screen bracket 4 are parallel to each other and are all horizontal, so even if the ceiling-mounted screen bracket 4 deviates due to bolt positioning fluctuations in the front-rear or left-right directions, the horizontality of the ceiling-mounted screen mounting surface can still be guaranteed; the ceiling-mounted screen bracket 4 is positioned on the rear sunroof reinforcing ring 3 using the two rear self-positioning holes, eliminating the need for assembly fixtures and jigs to ensure relative positioning with the vehicle body. The design reduces assembly costs and improves assembly efficiency. The ceiling screen body 5 has a built-in positioning pin that cooperates with the positioning holes on the ceiling screen bracket 4 to achieve positioning of the ceiling screen body 5 and the ceiling screen bracket 4. The ceiling screen body 5 and the ceiling screen bracket 4 can be installed before or after the ceiling 7 is installed, avoiding the need to remove the ceiling 7 when performing after-sales maintenance or replacing the ceiling screen body 5, thus reducing after-sales workload. The ceiling screen body 5, ceiling screen bracket 4, decorative cover and ceiling 7 are developed as special parts and are only used in configurations that require the ceiling screen. The roof assembly is a universal part for the entire series, reducing the types of body frame. By setting the horizontal overlap of the ceiling screen decorative cover 6 and the ceiling 7 reinforcing frame, it is possible to control the small gap between the ceiling screen decorative cover 6 and the ceiling 7 and improve the refinement.
