[0029] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The vehicle according to an embodiment of the present invention is described below with reference to the accompanying drawings. Figures 1-8 As shown, the vehicle according to an embodiment of the present invention includes a vehicle body 1000 and a panoramic glass. The vehicle body 1000 includes a first rear side panel 200, a second rear side panel 300, and a rear roof crossbeam 100. The rear roof crossbeam 100 is connected to each of the first rear side panel 200 and the second rear side panel 300.

[0031] The rear top beam 100 includes a first beam 1, a second beam 2, a connecting portion 3, and a glass support portion 4. The first beam 1 and the second beam 2 are spaced apart along the height direction of the rear top beam 100. The connecting portion 3 is connected to each of the first beam 1 and the second beam 2. The glass support portion 4 is connected to at least one of the first beam 1 and the connecting portion 3. The glass support portion 4 extends away from the first beam 1 along the width direction of the rear top beam 100.

[0032] The first edge of the skylight glass is supported by the glass support part 4 of the rear top beam 100, and the portion of the skylight glass adjacent to the first edge is supported by the first beam body 1 of the rear top beam 100.

[0033] According to an embodiment of the present invention, the rear roof beam 100 is provided with a glass support portion 4 extending away from the first beam body 1 along the width direction of the rear roof beam 100. This allows the first beam body 1 to support the portion of the sunroof glass adjacent to its first edge, and the glass support portion 4 to support the first edge of the sunroof glass. This effectively reduces or eliminates the overhang of the sunroof glass, thereby not only effectively improving the installation performance and strength of the sunroof glass, but also making the rear appearance of the vehicle more aesthetically pleasing.

[0034] Therefore, by utilizing the rear roof crossbeam 100 and vehicle body 1000 according to the embodiments of the present invention, the installation performance of the panoramic glass can be effectively improved, the installation strength of the panoramic glass can be increased, and the rear appearance of the vehicle can be made more aesthetically pleasing. Accordingly, the vehicle according to the embodiments of the present invention has advantages such as good installation performance of the panoramic glass, high installation strength of the panoramic glass, and a more aesthetically pleasing appearance.

[0035] like Figures 1-8 As shown, the vehicle includes a body 1000 and a panoramic glass roof. The body 1000 includes a first rear side panel 200, a second rear side panel 300, and a rear roof crossbeam 100. The first rear side panel 200 and the second rear side panel 300 are spaced apart along the width direction of the body 1000 (vehicle) (the length direction of the rear roof crossbeam 100). The width direction of the body 1000 (vehicle) is as follows: Figure 1 As shown by arrow A in the diagram, the length direction of the rear top crossbeam 100 is as follows: Figure 2 As shown by arrow B in the diagram.

[0036] For example, the first rear side panel 200 and the second rear side panel 300 are spaced apart in the left and right direction, the left end of the rear top beam 100 is connected to the first rear side panel 200, and the right end of the rear top beam 100 is connected to the second rear side panel 300.

[0037] The rear roof crossbeam 100 includes a first beam 1, a second beam 2, a connecting portion 3, and a glass support portion 4. The first beam 1 and the second beam 2 are spaced apart along the height direction of the rear roof crossbeam 100, and the height direction of the rear roof crossbeam 100 is consistent with the height direction of the vehicle body 1000 (vehicle). For example, the first beam 1 is located above the second beam 2. The height direction of the rear roof crossbeam 100 is as follows: Figure 3 As shown by arrow C in the diagram.

[0038] like Figures 3-5 As shown, the connecting part 3 has a first end 31 and a second end 32 that are opposite each other in the height direction of the rear top beam 100. The first end 31 (e.g., the upper end 34) of the connecting part 3 is connected to both the end of the first beam 1 and the end of the glass support part 4, and the second end 32 (e.g., the lower end 35) of the connecting part 3 is connected to the end of the second beam 2.

[0039] The first beam 1 and the second beam 2 extend from the connecting part 3 in opposite directions along the width of the rear top crossbeam 100, that is, the first beam 1 and the second beam 2 extend from the connecting part 3 in opposite directions along the width of the rear top crossbeam 100. The width direction of the rear top crossbeam 100 is consistent with the length direction of the vehicle body 1000 (vehicle). This makes the structure of the rear top crossbeam 100 simpler and more reasonable, and also reduces the difficulty of demolding the rear top crossbeam 100 during casting. The length direction of the vehicle body 1000 (vehicle) is as follows: Figure 1 As shown by arrow D in the diagram, the width direction of the rear top crossbeam 100 is as follows: Figure 3 and Figure 4 As shown by arrow E in the diagram.

[0040] For example, the upper end 34 of the connecting part 3, the rear end 11 of the first beam 1, and the front end 43 of the glass support part 4 are connected to each other, and the lower end 35 of the connecting part 3 is connected to the front end 21 of the second beam 2. That is, the first beam 1 extends forward from the connecting part 3, and the glass support part 4 and the second beam 2 extend backward from the connecting part 3. Thus, the first beam 1, the connecting part 3, and the second beam 2 are generally Z-shaped.

[0041] Optionally, the first beam 1, the second beam 2, the connecting part 3, and the glass support part 4 are integrally formed. By integrally forming the first beam 1, the second beam 2, the connecting part 3, and the glass support part 4, the structural strength of the rear top crossbeam 100 can be effectively improved. This not only significantly improves the torsional stiffness and modal performance of the rear top crossbeam 100 and the vehicle body 1000 to enhance the vehicle's NVH performance, but also eliminates the need for an internal cavity in the rear top crossbeam 100 to meet NVH performance requirements.

[0042] Compared to the existing rear roof crossbeam, this is equivalent to eliminating the lower plate of the rear roof crossbeam. This not only increases the rear headroom of the vehicle (by approximately 15-20 mm) to improve passenger comfort, but also reduces the weight of the rear roof crossbeam 100, thereby reducing the weight of the vehicle body 1000 and the vehicle as a whole.

[0043] Furthermore, by integrally molding the first beam 1, the second beam 2, the connecting part 3, and the glass support part 4, the secondary loading process in the existing rear top beam can be eliminated, thereby simplifying the manufacturing process of the rear top beam 100 and improving the production efficiency of the rear top beam 100.

[0044] Optionally, the first beam 1, the second beam 2, the connecting part 3, and the glass support part 4 are integrally die-cast from aluminum alloy. In other words, the rear top beam 100 is made of aluminum alloy. This reduces the manufacturing cost of the rear top beam 100 while ensuring its torsional stiffness and modal performance.

[0045] The first beam 1 is riveted to each of the first rear side panel 200 and the second rear side panel 300, and the second beam 2 is riveted to each of the first rear side panel 200 and the second rear side panel 300. This allows the rear top crossbeam 100 to be connected to the first rear side panel 200 and the second rear side panel 300 more conveniently and securely, thereby improving the structural strength of the vehicle body 1000 and the vehicle.

[0046] For example, the left end of the first beam 1 and the left end of the second beam 2 are connected to the first rear side panel 200 by self-piercing riveting (SPR), and the right end of the first beam 1 and the right end of the second beam 2 are connected to the second rear side panel 300 by self-piercing riveting.

[0047] The first beam 1, the second beam 2, and the connecting part 3 are plate-shaped. This allows the rear top crossbeam 100 to be connected to the first rear side panel 200 and the second rear side panel 300 more conveniently and stably, thereby improving the structural strength of the vehicle body 1000 and the vehicle.

[0048] like Figures 3-5 As shown, the first beam 1 has a first surface 12 and a second surface 13 opposite each other in the height direction of the rear top beam 100, with the first surface 12 being farther away from the second beam 2 in the height direction of the rear top beam 100 relative to the second surface 13. The glass support portion 4 has a third surface 41 and a fourth surface 42 opposite each other in the height direction of the rear top beam 100, with the third surface 41 being farther away from the second beam 2 in the height direction of the rear top beam 100 relative to the fourth surface 42. The first surface 12 and the third surface 41 are coplanar.

[0049] The first edge of the skylight glass is supported on the third surface 41 of the glass support 4, and the portion of the skylight glass adjacent to the first edge is supported on the first surface 12 of the first beam 1. By making the first surface 12 and the third surface 41 coplanar, the skylight glass can be installed on the rear top beam 100 more conveniently and easily, and the rear top beam 100 can support the skylight glass more stably, thereby further improving the installation performance and strength of the skylight glass.

[0050] The first surface 12 can be the upper surface of the first beam 1, and the second surface 13 can be the lower surface of the first beam 1. The third surface 41 can be the upper surface of the second beam 2, and the fourth surface 42 can be the lower surface of the second beam 2.

[0051] like Figure 2 and Figure 6 As shown, the first beam 1 has a first tailgate mounting portion 14 and a second tailgate mounting portion 15, which are spaced apart along the length direction of the first beam 1 (the length direction of the rear top crossbeam 100). The tailgate of the vehicle is mounted to the first beam 1 via the first tailgate mounting portion 14 and the second tailgate mounting portion 15.

[0052] By providing a first tailgate mounting part 14 and a second tailgate mounting part 15 on the first beam 1, the tailgate can be supported not only by the first beam 1 but also by the connecting part 3 and the second beam 2, thus providing more stable support for the tailgate. Furthermore, compared to mounting the tailgate on the second beam 2 (lower beam), mounting the tailgate on the first beam 1 prevents interference between the first beam 1, the connecting part 3, and the tailgate.

[0053] like Figure 2 and Figure 6 As shown, the first beam 1 has a first plate portion 16 and a second plate portion 17. The first plate portion 16 constitutes a first tailgate mounting portion 14, and the second plate portion 17 constitutes a second tailgate mounting portion 15. In other words, the first plate portion 16 and the second plate portion 17 are spaced apart along the length direction of the first beam 1.

[0054] The first plate portion 16 is provided with a first mounting hole 181, and the second plate portion 17 is provided with a second mounting hole 182. A first hinge is mounted on the first plate portion 16 through the first mounting hole 181, and a second hinge is mounted on the second plate portion 17 through the second mounting hole 182. The tailgate is mounted on the first beam 1 through the first hinge and the second hinge.

[0055] The first plate portion 16 and the second plate portion 17 are recessed along the height direction of the rear top crossbeam 100 relative to the rest of the first beam 1 and toward the adjacent second beam 2 to form a first receiving cavity 191 and a second receiving cavity 192. That is, the first plate portion 16 constitutes the bottom plate of the first receiving cavity 191, and the second plate portion 17 constitutes the bottom plate of the second receiving cavity 192. By providing the first receiving cavity 191 and the second receiving cavity 192, the first hinge can be accommodated in the first receiving cavity 191 and the second hinge can be accommodated in the second receiving cavity 192, so that the vehicle structure can be made more compact.

[0056] like Figures 2-5 As shown, the rear top beam 100 also includes an extension plate 6, which includes a plate body 61 and a flange 62. The plate body 61 is riveted to the second beam body 2, and the plate body 61 extends away from the first beam body 1 along the width direction of the rear top beam 100.

[0057] The flange 62 is connected to the plate 61, and the flange 62 extends along the height direction of the rear top beam 100 towards the adjacent first beam 1. The dimension of the flange 62 in the height direction of the rear top beam 100 is less than or equal to a first preset value, and the distance between the second beam 2 and the first beam 1 in the height direction of the rear top beam 100 is less than or equal to a second preset value.

[0058] The flange 62 not only contacts the tailgate seal for sealing but also connects to the water channel. By riveting the plate 61 to the second beam 2, the material of the extension plate 6 does not need to be the same as that of the second beam 2, thus expanding the range of material choices for the extension plate 6. This allows the material of the extension plate 6 to be the same as that of the water channel, enabling the flange 62 to be welded to the water channel, thereby effectively reducing the dimension of the flange 62 in the height direction of the rear top crossbeam 100.

[0059] Since the flanged portion 62 contacts the tailgate seal, by reducing the dimension of the flanged portion 62 in the height direction of the rear top crossbeam 100, the distance between the plate 61 and the second beam 2 in the height direction of the rear top crossbeam 100 and the tailgate seal can be reduced. In other words, compared with the prior art of riveting the flanged portion and the water channel, the height of the second beam 2 can be increased to reduce the distance between the second beam 2 and the tailgate seal in the height direction of the rear top crossbeam 100, thereby increasing the rear upper visibility of the vehicle.

[0060] Optionally, the first beam 1, the second beam 2, the connecting part 3, and the glass support part 4 are integrally die-cast from aluminum alloy, and the extension plate 6 is made of steel, i.e., the extension plate 6 is a steel plate. The plate 61 is riveted to the second beam 2, and the plate 61 extends rearward from the second beam 2. The flange 62 is connected to the plate 61, and the flange 62 extends upward from the plate 61. The water trough is made of steel.

[0061] The dimension of the flange 62 in the height direction of the rear top crossbeam 100 (the height of the flange 62) is less than or equal to 14 mm, and the distance between the second beam 2 and the first beam 1 in the height direction of the rear top crossbeam 100 is less than or equal to 64 mm. Further optionally, the dimension of the flange 62 in the height direction of the rear top crossbeam 100 is greater than or equal to 12 mm and less than or equal to 14 mm, and the distance between the second beam 2 and the first beam 1 in the height direction of the rear top crossbeam 100 is greater than or equal to 62 mm and less than or equal to 64 mm.

[0062] In the related technology, the extension plate is made of aluminum, and the flanged portion of the extension plate is riveted to the drainage channel. To meet the riveting process requirements, the flanged portion in the related technology has a dimension of at least 26 mm in the height direction of the rear top crossbeam.

[0063] Therefore, this application can reduce the height of the flange 62 by at least 12 mm. Correspondingly, this application can increase the height of the second beam 2 by at least 12 mm, that is, move the second beam 2 upward by at least 12 mm, in order to increase the rear upper visibility of the vehicle.

[0064] like Figure 7 and Figure 8As shown, the rear top crossbeam 100 also includes a plurality of transverse reinforcing ribs 51, which are spaced apart along the length of the rear top crossbeam 100. Each transverse reinforcing rib 51 is connected to each of the first beam 1 and the connecting part 3. Each transverse reinforcing rib 51 has a wire passage 514 extending along the length of the rear top crossbeam 100. This not only increases the structural strength of the first beam 1 and the connecting part 3 (rear top crossbeam 100), but also allows the wiring harness to be integrated within the rear top crossbeam 100, thereby reducing the space occupied by the wiring harness and increasing the rear headroom of the vehicle.

[0065] Optionally, each transverse stiffener 51 includes a first edge 511, a second edge 512, and a third edge 513. The first edge 511 is connected to the first beam 1, and the second edge 512 is connected to the connecting portion 3. One end of the third edge 513 is connected to the first edge 511, and the other end of the third edge 513 is connected to the second edge 512. The third edge 513 is an arc-shaped depression towards the connection between the first beam 1 and the connecting portion 3, and the third edge 513 defines a wire groove 514. This makes the structure of the transverse stiffener 51 simpler and more reasonable.

[0066] For example, the upper edge of the transverse reinforcing rib 51 is connected to the lower surface of the first beam 1, and the rear edge of the first beam 1 is connected to the front surface 33 of the connecting part 3. The third edge 513 is an arc shape that is concave upward and backward.

[0067] like Figure 7 and Figure 8 As shown, the rear top beam 100 also includes a first longitudinal reinforcing rib 52, which is disposed on the first beam body 1 and extends along the length direction of the rear top beam 100. The first longitudinal reinforcing rib 52 is connected to the end of each transverse reinforcing rib 51. An installation space 56 is formed between the first longitudinal reinforcing rib 52 and the transverse reinforcing rib 51. For example, the first longitudinal reinforcing rib 52 is connected to the front end of each transverse reinforcing rib 51.

[0068] By providing the first longitudinal stiffener 52, the structural strength of the first beam 1 and the rear top crossbeam 100 can be further increased. Furthermore, by connecting the first longitudinal stiffener 52 to the end of each transverse stiffener 51, an installation space 56 can be formed between the first longitudinal stiffener 52 and the transverse stiffeners 51. Existing vehicle components can be installed in the installation space 56 to make the vehicle structure more compact. Additional components can also be installed in the installation space 56. For example, damping elements can be installed in the installation space 56 to further improve the vehicle's NVH performance.

[0069] like Figure 7 and Figure 8As shown, the rear top beam 100 also includes a second longitudinal stiffener 53, a third longitudinal stiffener 54, and a connecting stiffener 55. The second longitudinal stiffener 53 and the third longitudinal stiffener 54 are spaced apart along the width direction of the rear top beam 100 in the second beam body 2. Both the second longitudinal stiffener 53 and the third longitudinal stiffener 54 extend along the length direction of the rear top beam 100.

[0070] The connecting stiffener 55 is corrugated and is located on the second beam 2. In the width direction of the rear top beam 100, the connecting stiffener 55 is positioned between the second longitudinal stiffener 53 and the third longitudinal stiffener 54, and is connected to both the second longitudinal stiffener 53 and the third longitudinal stiffener 54. This further improves the structural strength of the second beam 2 and the rear top beam 100.

[0071] Optionally, the second longitudinal stiffener 53, the third longitudinal stiffener 54, and the connecting stiffener 55 are disposed on the lower surface 22 of the second beam 2, with the second longitudinal stiffener 53 located in front of the third longitudinal stiffener 54. The crest (front part) of the connecting stiffener 55 is connected to the second longitudinal stiffener 53, and the trough (rear part) of the connecting stiffener 55 is connected to the third longitudinal stiffener 54.

[0072] Optionally, the second longitudinal stiffener 53 is connected to each transverse stiffener 51. This can further improve the structural strength of the rear top beam 100. For example, the lower end 515 of each transverse stiffener 51 is connected to the second longitudinal stiffener 53.

[0074] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
