[0039] like Figure 1-Figure 3As shown, this embodiment provides a roof cross beam reinforcement plate 400, including a first reinforcement plate 41 and a second reinforcement plate 42, the first reinforcement plate 41 includes a first mounting portion 411 and a first connecting portion 412 connected to each other, the first mounting portion 411 is connected to the roof outer panel 100; the second reinforcement plate 42 includes a second mounting portion 421 and a second connecting portion 422 connected to each other, the second mounting portion 421 is connected to the roof outer panel 100, and the second connecting portion 422 is adjustably connected to the first connecting portion 412 to adjust the height of the second mounting portion 421.

[0040] The roof cross beam reinforcement plate 400 provided in this embodiment divides the roof cross beam reinforcement plate 400 into two independent structures, a first reinforcement plate 41 and a second reinforcement plate 42. By adjusting the relative position of the first connecting portion 412 and the second connecting portion 422, the relative height of the first mounting portion 411 and the second mounting portion 421 can be adjusted, so that the roof cross beam reinforcement plate 400 can be adapted to be installed at any position of the roof outer panel 100, thereby reducing costs and shortening production cycles.

[0041] Optionally, in order to adjust the relative height of the first mounting portion 411 and the second mounting portion 421 , an oblong hole 423 is provided on one of the first connecting portion 412 and the second connecting portion 422 , and a round hole 413 is provided on the other of the two.

[0043] Specifically, the oblong hole 423 extends along the width direction of the second connecting portion 422 , that is, the oblong hole 423 is substantially perpendicular to the top cover outer panel 100 , thereby achieving adjustment of the height of the second mounting portion 421 .

[0044] Preferably, the diameter of the oblong hole 423 is 8 mm and the length is 12 mm, and the diameter of the circular hole 413 is 8 mm.

[0045] Preferably, the first connection portion 412 and the second connection portion 422 are fixedly connected by fasteners. For example, at the oblong hole 423 and the round hole 413, the first connection portion 412 and the second connection portion 422 are fixedly connected by the cooperation of bolts and nuts, and the height of the second reinforcing plate 42 can be adjusted by loosening and tightening the nuts according to actual conditions.

[0046] Exemplarily, the bolt is a bearing surface projection weld bolt.

[0047] Further, in this embodiment, the number of the oblong holes 423 and the number of the round holes 413 are both three.

[0048] Preferably, if Figure 3 As shown, a first glue coating groove 414 is provided on the first mounting portion 411, and an expansion damping glue 700 is provided in the first glue coating groove 414, so as to better connect with the top cover outer plate 100 and improve the anti-dent performance of the top cover.

[0051] Furthermore, a plurality of second glue coating grooves 424 are arranged on the second mounting portion 421 along the length direction of the roof cross beam reinforcement plate 400 .

[0052] Optionally, the second reinforcing plate 42 is L-shaped, and the first reinforcing plate 41 and the second reinforcing plate 42 are fixedly connected to form a "J"-shaped structure, so as to better connect with the top cover outer plate 100 and improve the anti-dent performance of the top cover.

[0053] Preferably, the first reinforcing plate 41 is integrally formed. Specifically, the first reinforcing plate 41 is integrally formed by stamping.

[0054] Further, the second reinforcing plate 42 is integrally formed. Specifically, the second reinforcing plate 42 is integrally formed by stamping.

[0055] like Figure 4 Combination Figure 3 As shown, this embodiment also provides a vehicle, which can reduce costs and shorten production cycles by applying the above-mentioned roof cross beam reinforcement plate 400. The vehicle includes a roof cross beam reinforcement plate 400 and a roof outer panel 100, and the roof cross beam reinforcement plate 400 includes a first reinforcement plate 41 and a second reinforcement plate 42. The first reinforcement plate 41 includes a first mounting portion 411 and a first connecting portion 412 connected to each other, and the first mounting portion 411 is connected to the roof outer panel 100; the second reinforcement plate 42 includes a second mounting portion 421 and a second connecting portion 422 connected to each other, and the second mounting portion 421 is connected to the roof outer panel 100, and the second connecting portion 422 is fixedly connected to the first connecting portion 412 in an adjustable position to adjust the height of the second mounting portion 421.

[0056] According to research, for large SUVs or MPVs, due to their longer body sizes, except for the front and rear areas of the roof, which have large changes in the curvature of the roof surface to meet wind resistance requirements, the middle area of ​​the roof is relatively flat. In order to achieve a good bonding effect, the gap between the roof outer panel 100 and the roof crossbeam is generally 2.5mm or 3mm. Considering that the curvature of the common roof crossbeam flange surface is inconsistent with the curvature of the roof outer panel 100, the gap between the common roof crossbeam and the roof outer panel 100 is controlled between 2mm-3mm to meet the gluing requirements.

[0057] Preferably, in order to facilitate adjustment of the relative height between the first mounting portion 411 and the second mounting portion 421 , an oblong hole 423 is provided on one of the first connecting portion 412 and the second connecting portion 422 , and a round hole 413 is provided on the other of the two.

[0058] Preferably, a plurality of oblong holes 423 are arranged on the second connection portion 422 along the length direction of the roof cross beam reinforcement plate 400. Further, a plurality of round holes 413 are arranged on the first connection portion 412 along the length direction of the roof cross beam reinforcement plate 400. The relative height of the first mounting portion 411 and the second mounting portion 421 can be adjusted by the cooperation of the oblong holes 423 and the round holes 413.

[0059] Specifically, the oblong hole 423 extends along the width direction of the second connecting portion 422 , that is, the oblong hole 423 is substantially perpendicular to the top cover outer panel 100 , thereby achieving adjustment of the height of the second mounting portion 421 .

[0060] Preferably, the diameter of the oblong hole 423 is 8 mm and the length is 12 mm, and the diameter of the circular hole 413 is 8 mm.

[0061] Exemplarily, the number of the oblong holes 423 and the number of the round holes 413 are both three.

[0062] Since the longer the spacing distance, the greater the change in the curvature difference of the top cover outer panel 100, the design of a common top cover crossbeam structure between the middle position of the top cover outer panel 100 and the rear edge of the top cover outer panel can reduce the curvature difference of the top cover outer panel 100.

[0063] like Figure 4 As shown, the vehicle further includes a roof front cross beam 200, a roof middle cross beam 300 and a roof rear cross beam 500, and the roof middle cross beam 300 is located between the roof front cross beam 200 and the roof rear cross beam 500 to support the middle position of the roof outer panel 100.

[0064] Furthermore, the roof cross beam reinforcement plate 400 is disposed between the roof middle cross beam 300 and the roof rear cross beam 500 to improve the dent resistance and rigidity of the roof outer panel 100 at the rear half.

[0065] Preferably, a plurality of roof cross beam reinforcement plates 400 are arranged along the length direction of the roof outer panel 100. The more the number of the roof cross beam reinforcement plates 400, the stronger the dent resistance of the roof.

[0066] Exemplarily, in order to take into account the requirements of vehicle body lightweight, three roof cross beam reinforcement plates 400 are arranged along the length direction of the roof outer panel 100.

[0067] Further, the vehicle further includes side wall reinforcement plates 600. Two side wall reinforcement plates 600 are symmetrically arranged at both ends of the roof outer panel 100 along the width direction of the roof outer panel 100.

[0068] Preferably, both ends of the roof cross beam reinforcement plate 400 are respectively connected to the side wall reinforcement plate 600 to form a structure in the shape of the Chinese character 'Ri' (日).

[0069] Specifically, the roof cross beam reinforcement plate 400 and the side wall reinforcement plate 600 are fixedly connected by welding.

[0070] As Figure 5-Figure 7 shown, preferably, the roof middle cross beam 300 includes a first fixing part 31, a first strengthening groove 32, a second fixing part 33, a second strengthening groove 34 and a third fixing part 35 which are arranged in sequence. The first fixing part 31, the second fixing part 33 and the third fixing part 35 are all connected to the roof outer panel 100, and expansion damping rubber 700 is arranged between the first fixing part 31, the second fixing part 33, the third fixing part 35 and the roof outer panel 100. The roof middle cross beam 300 can improve the dent resistance of the roof middle cross beam 300 while ensuring the internal space, meeting the requirements of vehicle body lightweight and having low cost.

[0071] Further, the first strengthening groove 32 extends along the length direction of the roof middle cross beam 300 to improve the dent resistance of the roof outer panel 100. Briefly speaking, the first strengthening groove 32 extends along the width direction of the roof outer panel 100. Since the length of the roof outer panel 100 is greater than the width of the roof outer panel 100, the roof outer panel 100 is prone to deformation in the length direction. Therefore, making the first strengthening groove 32 extend along the width direction of the roof outer panel 100 can improve the dent resistance of the roof outer panel 100 while taking into account the elastic deformation ability of the roof outer panel 100.

[0072] Optionally, reinforcing ribs 321 are arranged on the bottom surface of the first strengthening groove 32 to further improve the anti - deformation ability of the first strengthening groove 32.

[0073] Further, a plurality of reinforcing ribs 321 are uniformly arranged along the extending direction of the first strengthening groove 32.

[0074] Illustratively, in this embodiment, two reinforcing ribs 321 are symmetrically arranged at both ends of the first reinforcing groove 32 , which improves the deformation resistance of the first reinforcing groove 32 and facilitates processing and forming.

[0075] Optionally, the first reinforcement groove 32 is a rectangular groove to facilitate stamping and forming.

[0076] Preferably, the second reinforcement groove 34 extends along the length direction of the top cover middle cross beam 300 to improve the anti-dent performance of the top cover outer panel 100. In short, the second reinforcement groove 34 extends along the width direction of the top cover outer panel 100. Since the length of the top cover outer panel 100 is greater than the width of the top cover outer panel 100, the top cover outer panel 100 is easily deformed in the length direction. Extending the second reinforcement groove 34 along the width direction of the top cover outer panel 100 can improve the anti-dent performance of the top cover outer panel 100 while increasing the elastic deformation capacity of the top cover outer panel 100.

[0077] Optionally, the second reinforcement groove 34 is an I-shaped groove to improve the deformation resistance of the second reinforcement groove 34 .

[0078] Preferably, a first fixing portion glue groove 311 is provided on the first fixing portion 31, and the expansion damping glue 700 is provided in the first fixing portion glue groove 311. The expansion damping glue 700 is provided in the first fixing portion glue groove 311. On the one hand, the amount of the expansion damping glue 700 can be increased to improve the anti-dent performance of the top cover outer panel 100; on the other hand, the position of the expansion damping glue 700 can be prevented from being offset.

[0079] Furthermore, a second fixing portion glue coating groove 331 is provided on the second fixing portion 33, and the expansion shock-absorbing glue 700 is provided in the second fixing portion glue coating groove 331, which can also achieve the above-mentioned effect.

[0080] Furthermore, a third fixing portion glue coating groove 351 is provided on the third fixing portion 35, and the expansion shock-absorbing glue 700 is provided in the third fixing portion glue coating groove 351, which can also achieve the above-mentioned effect.

[0081] The middle cross beam 300 of the top cover provided in this embodiment can increase the number of glue coating grooves by optimizing the structure of the middle cross beam 300 of the top cover without changing the shape of the top cover outer panel 100 and without adding a reinforcing plate, thereby achieving the purpose of improving the anti-dent performance of the top cover.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
