[0035] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0036] Reference below Figure 1-Figure 6 As shown, a roof rear cross beam structure 100 according to an embodiment of the present invention is described.

[0037] Reference Figure 1 and Figure 2 As shown, the roof rear cross beam structure 100 of the first embodiment of the utility model comprises: a rear cross beam top plate 10, a rear cross beam bottom plate 20, a D-pillar inner plate 30, a hinge reinforcement plate 40 and a connecting plate 50. The rear cross beam top plate 10 is provided with a first hinge mounting portion 11, the rear cross beam bottom plate 20 is connected to the lower part of the rear cross beam top plate 10, the D-pillar inner plate 30 is connected to the lower part of the rear cross beam top plate 10, and the D-pillar inner plate 30 is connected to one side of the rear cross beam bottom plate 20, the hinge reinforcement plate 40 is respectively connected to the rear cross beam top plate 10, the rear cross beam bottom plate 20 and the D-pillar inner plate 30, the hinge reinforcement plate 40 is provided with a second hinge mounting portion 41 corresponding to the first hinge mounting portion 11, and the connecting plate 50 is respectively connected to the rear cross beam top plate 10, the rear cross beam bottom plate 20, the D-pillar inner plate 30 and the hinge reinforcement plate 40.

[0038] Specifically, the strength of the tailgate hinge installation point in the traditional rear cross beam structure is relatively weak, and the tailgate hinge installation point is generally composed of the upper plate of the rear cross beam of the top cover, the reinforcement plate of the rear cross beam of the top cover, the lower plate of the rear cross beam of the top cover, and the inner plate of the D-pillar. The strength of the tailgate hinge installation point is generally increased by increasing the thickness of the upper plate of the rear cross beam of the top cover, the reinforcement plate of the rear cross beam of the top cover, the lower plate of the rear cross beam of the top cover, and the inner plate of the D-pillar. In this way, the traditional rear cross beam structure of the top cover can only be increased in weight by adding features locally and increasing the material thickness of parts, resulting in a heavier weight of the rear cross beam structure of the top cover, which also increases the cost. In addition, after the tailgate hinge installation point is stimulated, the rear cross beam of the top cover deforms violently on the surface in the direction of the tailgate hinge installation point, resulting in the force on the tailgate hinge installation point cannot be transmitted to the overall structure of the vehicle, and the overall structure of the vehicle is the entire body of the vehicle.

[0039] Therefore, it is necessary to optimize the design of the roof rear cross beam structure 100. The rear cross beam top plate 10 is provided with a first hinge mounting portion 11, which can facilitate the installation of the vehicle's tailgate. The rear cross beam bottom plate 20 is connected to the bottom of the rear cross beam top plate 10. The rear cross beam bottom plate 20 can provide support for the rear cross beam top plate 10 and can also improve the strength of the rear cross beam top plate 10. The D-pillar inner plate 30 is connected to one side of the rear cross beam bottom plate 20, so that the D-pillar inner plate 30 can further increase the strength of the rear cross beam bottom plate 20.

[0040] Furthermore, the hinge reinforcement plate 40 is respectively connected to the rear cross beam top plate 10, the rear cross beam bottom plate 20 and the D-pillar inner plate 30, and the hinge reinforcement plate 40 is provided with a second hinge mounting portion 41 corresponding to the first hinge mounting portion 11. In this way, not only the strength of the hinge reinforcement plate 40 can be improved, but when the second hinge mounting portion 41 is subjected to external force, the second hinge mounting portion 41 can transfer the force to the rear cross beam top plate 10, the rear cross beam bottom plate 20 and the D-pillar inner plate 30, and the force applied to the second hinge mounting portion 41 can be dispersed, thereby reducing the force applied to the second hinge mounting portion 41.

[0041] In addition, the roof rear cross beam structure 100 is provided with a connecting plate 50, and the connecting plate 50 is respectively connected to the rear cross beam top plate 10, the rear cross beam bottom plate 20, the D-pillar inner plate 30 and the hinge reinforcement plate 40. In this way, the connecting plate 50 is fixedly connected to the rear cross beam top plate 10 and the rear cross beam bottom plate 20, so that the strength between the rear cross beam top plate 10 and the rear cross beam bottom plate 20 can be improved, and when the first hinge mounting portion 11 and the second hinge mounting portion 41 are both subjected to external force, the deformation of the rear cross beam top plate 10 and the rear cross beam bottom plate 20 when being stimulated can be reduced, and the force can also be transmitted to the skylight and the overall structure of the vehicle, so that the force of the first hinge mounting portion 11 and the second hinge mounting portion 41 can be dispersed to the overall structure of the vehicle, and the strength of the first hinge mounting portion 11 and the second hinge mounting portion 41 can also be improved.

[0042] Therefore, the setting of the connecting plate 50 in the roof rear cross beam structure 100 can reduce the deformation of the rear cross beam top plate 10 and the rear cross beam bottom plate 20 when stimulated, and can also transfer the force of the first hinge mounting part 11 and the second hinge mounting part 41 to the skylight and the overall structure of the vehicle, thereby improving the strength of the first hinge mounting part 11 and the second hinge mounting part 41.

[0043] According to some embodiments of the present invention, Figure 2 and Figure 3As shown, the connecting plate 50 includes: a main board 51, a top flange 52 and a bottom flange 53, the top flange 52 is bent and connected to the top of the main board 51, and the top flange 52 is connected to the rear cross beam top plate 10, the bottom flange 53 is bent and connected to the bottom of the main board 51, and the bottom flange 53 is respectively connected to the rear cross beam bottom plate 20, the D-pillar inner plate 30 and the hinge reinforcement plate 40.

[0044] The top flange 52 is bent and connected to the top of the main plate 51, so that the contact area between the top flange 52 and the rear beam top plate 10 can be increased, and the connection strength between the top flange 52 and the rear beam top plate 10 can also be increased. When the first hinge mounting portion 11 and the second hinge mounting portion 41 are subjected to external force, the external force can be transmitted to the rear beam top plate 10 through the top flange 52 of the connecting plate 50.

[0045] In addition, the bottom flange 53 is bent and connected to the bottom of the main board 51, and the bottom flange 53 is respectively connected to the rear cross beam bottom plate 20, the D-pillar inner plate 30 and the hinge reinforcement plate 40, so that the contact area between the bottom flange 53 and the rear cross beam bottom plate 20 can be increased, and the bottom flange 53, the rear cross beam bottom plate 20, the D-pillar inner plate 30 and the hinge reinforcement plate 40 are stacked, which can further increase the connection strength between the bottom flange 53 and the rear cross beam bottom plate 20, the D-pillar inner plate 30 and the hinge reinforcement plate 40. When the first hinge mounting portion 11 and the second hinge mounting portion 41 are subjected to external force, the external force can be attenuated through the rear cross beam bottom plate 20, the D-pillar inner plate 30 and the hinge reinforcement plate 40, and then the attenuated external force is transmitted to the rear cross beam top plate 10 through the connecting plate 50 for further attenuation, and finally, the attenuated external force is transmitted to the overall structure of the vehicle through the rear cross beam top plate 10.

[0046] According to some embodiments of the present invention, Figure 1 As shown, the rear cross beam top plate 10 includes: a front plate 101, a middle plate 102 and a rear plate 103, the middle plate 102 is connected between the front plate 101 and the rear plate 103, the middle plate 102 is bent relative to the front plate 101 and the rear plate 103, wherein the front plate 101 is used to fit with the canopy, the rear plate 103 is provided with a first hinge mounting portion 11, and the top flange 52 is respectively connected to the front plate 101 and the rear plate 103.

[0047] Specifically, the front plate 101 in the rear cross beam top plate 10 is fitted with the skylight, and the rear plate 103 is provided with a first hinge mounting portion 11. When the rear plate 103 is provided with the first hinge mounting portion 11 and is subjected to force, the force of the first hinge mounting portion 11 can be transmitted to the middle plate 102 and the front plate 101. Since the front plate 101 is fitted with the skylight, the force received by the front plate 101 can be transmitted to the skylight and then to the vehicle body, thereby reducing the force on the first hinge mounting portion 11 and avoiding deformation of the first hinge mounting portion 11.

[0048] Also, if Figure 1 and Figure 3 As shown, the top flange 52 is connected to the front plate 101 and the rear plate 103 respectively, so that the contact area between the top flange 52 and the rear beam top plate 10 can be further increased, and the connection position between the top flange 52 and the rear beam top plate 10 can also be increased, which can not only further improve the strength of the rear beam top plate 10, but also make the connection between the top flange 52 and the rear beam top plate 10 more stable and firm.

[0049] According to some embodiments of the present invention, Figure 1 As shown, the front of the main board 51 is higher than the rear of the main board 51, and the top flange 52 includes: a first flange 521 and a second flange 522, the first flange 521 is connected to the front of the rear beam top plate 10, and the second flange 522 is located at the rear and lower part of the first flange 521, and the second flange 522 is connected to the rear of the rear beam top plate 10.

[0050] The front part of the main board 51 is higher than the rear part of the main board 51 , so that the front part of the main board 51 can be easily connected to the canopy.

[0051] In addition, the first flange 521 in the top flange 52 is connected to the front part of the rear cross beam top plate 10, so that the first flange 521 can support the front part of the rear cross beam top plate 10. The second flange 522 is located at the rear and lower part of the first flange 521, which can facilitate the second flange 522 to be fixedly connected to the rear plate 103. The second flange 522 is connected to the rear part of the rear cross beam top plate 10, so that the second flange 522 can provide support force to the rear cross beam top plate 10. Moreover, the first flange 521 is connected to the front part of the rear cross beam top plate 10, and the second flange 522 is connected to the rear part of the rear cross beam top plate 10, so that the path for the first hinge mounting part 11 to transmit force to the rear cross beam top plate 10 can be increased, and the force of the first hinge mounting part 11 can be transmitted to the front part of the rear cross beam top plate 10 through the first flange 521, and can also transmit force to the rear part of the rear cross beam top plate 10 through the second flange 522.

[0052] According to some embodiments of the present invention, Figure 3 and Figure 4 As shown, the bottom flange 53 includes: a third flange 531 and a fourth flange 532.

[0054] In addition, when the second hinge mounting portion 41 is subjected to external force, the second hinge mounting portion 41 will transfer the force to the hinge reinforcement plate 40, the D-pillar inner plate 30 and the rear cross beam bottom plate 20, and the rear cross beam bottom plate 20 will then transfer the attenuated force to the connecting plate 50 through the third flange 531, and finally transfer the attenuated force to the overall structure of the vehicle through the connecting plate 50.

[0055] Similarly, the fourth flange 532 is connected to the rear cross beam bottom plate 20, the D-pillar inner plate 30 and the hinge reinforcement plate 40 respectively, so that the fourth flange 532 can be connected to the rear cross beam bottom plate 20, the D-pillar inner plate 30 and the hinge reinforcement plate 40 more stably and firmly. When the second hinge mounting portion 41 is subjected to an external force, the second hinge mounting portion 41 transfers the force to the hinge reinforcement plate 40 and the rear cross beam bottom plate 20, and the rear cross beam bottom plate 20 then transfers the force to the connecting plate 50 through the fourth flange 532, and finally transfers the attenuated force to the overall structure of the vehicle through the connecting plate 50.
