[0034] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0035] The longitudinal beam 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0036] like Figure 1-Figure 4 As shown, the longitudinal beam 1 according to the embodiment of the present invention includes a web plate 100 , an upper wing plate 200 and a lower wing plate 300 .

[0037] The web 100 has a first end 110 and a second end 120 opposite to each other along its length direction, the first end 110 is provided with a cutting portion 121, the upper wing plate 200 is connected to one side of the web 100 in the width direction and is bent relative to the web 100, one end of the upper wing plate 200 extends to the side of the cutting portion 121 facing the second end 120, and the other end of the upper wing plate 200 is provided with an avoidance portion 210, and the lower wing plate 300 is connected to the other side of the web 100 in the width direction and is bent relative to the web 100.

[0038] It can be understood that the length direction of the longitudinal beam 1 is the front-to-back direction of the vehicle, that is, the length direction of the web 100 is the front-to-back direction of the vehicle, wherein the first end 110 of the web 100 can be the tail end of the web 100, and the second end 120 of the web 100 can be the front end of the web 100.

[0039] According to the longitudinal beam 1 of the embodiment of the utility model, a cutting portion 121 is set at the first end 110 of the web 100, and one end of the upper wing panel 200 extends to the side of the cutting portion 121 facing the second end 120. In this way, the longitudinal beam 1 can facilitate the cutting portion 121 to increase the spacing between it and other components (for example, the saddle of the vehicle), thereby avoiding position interference between the rear end of the web 100 and other components of the vehicle. At the same time, the upper wing panel 200 only extends to the side of the cutting portion 121 facing the second end 120, that is, the upper wing panel 200 does not cover the cutting portion 121. In this way, the upper wing panel 200 does not need to extend along the cutting portion 121, thereby avoiding the distance between the rear end of the upper wing panel 200 and the lower wing panel 300 from becoming smaller.

[0040] In addition, an avoidance portion 210 is provided at the other end of the upper wing panel 200, so that the longitudinal beam 1 can facilitate the avoidance portion 210 of the upper wing panel 200 to avoid components close to the front side of the vehicle, which is convenient for layout and installation, and at the same time can avoid position interference between the front end of the longitudinal beam 1 and other components of the vehicle.

[0041] Such an arrangement not only effectively avoids positional interference between the upper wing plate 200 and the web 100 of the longitudinal beam 1 and other components, but also the upper wing plate 200 does not need to completely cover the web 100 along the length direction of the longitudinal beam 1, thereby keeping the distance between the upper wing plate 200 and the lower wing plate 300 unchanged. For example, in the length direction of the longitudinal beam 1, the upper wing plate 200 and the lower wing plate 300 can be set with equal width, or the spacing between the upper wing plate 200 and the lower wing plate 300 can be not less than the width of the web 100. In this way, the longitudinal beam 1 can be formed not only by stamping but also by roll forming. The upper wing plate 200 and the lower wing plate 300 will not interfere with the rolling tooling, and there are more processing options. In addition, the longitudinal beam 1 of this embodiment is formed by roll forming, which is beneficial to improving the surface quality of the web 100 and reducing quality problems such as orange peel and indentation, thereby improving the production quality of the longitudinal beam 1 and greatly reducing the process defects of the longitudinal beam 1.

[0042] In this way, the longitudinal beam 1 according to the embodiment of the utility model can avoid position interference with other components, and is conducive to the processing of the longitudinal beam 1, which is conducive to improving the production quality of the longitudinal beam 1.

[0043] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the minimum spacing between the upper wing plate 200 and the lower wing plate 300 is not less than the maximum width of the web 100. In this way, when the longitudinal beam 1 is formed by stamping or roll forming, the upper wing plate 200 and the lower wing plate 300 will not interfere with the tooling, which is convenient for processing.

[0044] Furthermore, if Figure 3 and Figure 4 As shown, the upper wing panel 200 and the lower wing panel 300 are arranged in parallel and equidistantly.

[0045] In this way, when the longitudinal beam 1 is rolled, the tooling can be rolled from one end of the longitudinal beam 1 to the other end, that is, from one end of the web 100 to the other end, and the spacing between the upper wing plate 200 and the lower wing plate 300 is equal, and the rolled tooling can pass between the upper wing plate 200 and the lower wing plate 300. The upper wing plate 200 and the lower wing plate 300 will not interfere with the position of the tooling, and will not affect the rolling forming of the web 100, so that the longitudinal beam 1 can be formed by rolling processing.

[0046] In some specific embodiments of the present invention, at least the yield strength of the web 100 is not less than 620 MPa.

[0047] The thickness of the longitudinal beam 1 is D, and the thickness D of the longitudinal beam 1 satisfies: 6 mm ≤ D ≤ 7 mm. For example, the longitudinal beam 1 in the embodiment of the utility model can be a roll-formed longitudinal beam 1 made of 700L material with a thickness of 7 mm.

[0048] It should be noted that the thickness of the longitudinal beam in the related art is usually 8 mm, while in the embodiment of the utility model, by setting the thickness of the longitudinal beam 1 to be thinner, the weight of the longitudinal beam 1 can be greatly reduced, which is conducive to achieving lightweight of the longitudinal beam 1, and the yield strength of the web 100 is made not less than 620 MPa, so that the structural strength of the longitudinal beam 1 can be maintained at a high level, that is, while reducing the thickness of the longitudinal beam 1 to achieve lightweight of the longitudinal beam 1, the structural strength of the longitudinal beam 1 can still be ensured to be high, thereby meeting the use requirements of the longitudinal beam 1.

[0049] In some specific embodiments of the present invention, the longitudinal beam 1 is formed by rolling processing, which can improve the product quality of the longitudinal beam 1, make the surface quality of the longitudinal beam 1 higher, avoid orange peel and indentation problems, and make the thickness processing of the longitudinal beam 1 more uniform.

[0050] In some specific embodiments of the present invention, Figure 3 and Figure 4 As shown, the cutting portion 121 is provided on the upper side of the first end 110, and along the direction from the second end 120 to the first end 110, the cutting portion 121 gradually tilts toward the direction close to the lower wing plate 300. In other words, the closer to the tail end of the longitudinal beam 1, the larger the space between the upper sides of the longitudinal beam 1 can be, which more effectively avoids the position interference between the tail end of the longitudinal beam 1 and other components during the driving process of the vehicle, and the structural setting is more reasonable.

[0051] The frame 2 according to the embodiment of the utility model is described below with reference to the accompanying drawings. Figure 1 and Figure 2 As shown, the vehicle frame 2 includes a plurality of longitudinal beams 1 and a plurality of cross beams 400 according to the above-mentioned embodiment of the utility model, both ends of the cross beam 400 are respectively connected to the plurality of longitudinal beams 1 , and the plurality of cross beams 400 are spaced apart along the length direction of the longitudinal beams 1 .

[0052] The vehicle frame 2 according to the embodiment of the utility model can avoid position interference between the longitudinal beam 1 and other components by utilizing the longitudinal beam 1 according to the above embodiment of the utility model, and is beneficial to the processing of the longitudinal beam 1 and the improvement of the production quality of the longitudinal beam 1.

[0053] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the vehicle frame 2 further includes a first reinforcement beam 410 and a second reinforcement beam 420 .

[0054] The first reinforcing beam 410 is connected to the web 100 and the upper wing plate 200 , respectively. The second reinforcing beam 420 is connected to the web 100 and the lower wing plate 300 , respectively. The first reinforcing beam 410 is connected between the cross beam 400 and the longitudinal beam 1 .

[0055] Among them, the first reinforcing beam 410 and the second reinforcing beam 420 can both be constructed as triangular beams, that is, the first reinforcing beam 410 and the second reinforcing beam 420 can respectively include two beam surfaces that are bent to each other, one beam surface of the first reinforcing beam 410 is fitted and connected to the upper wing plate 200 and the other beam surface is fitted and connected to the web 100, one beam surface of the second reinforcing beam 420 is fitted and connected to the lower wing plate 300 and the other beam surface is fitted and connected to the web 100, which is beneficial to improving the structural strength of the frame 2, and the connection strength between the cross beam 400 and the longitudinal beam 1 is higher.

[0056] In addition, there may be multiple first reinforcing beams 410 , and the multiple first reinforcing beams 410 are arranged along the length direction of the longitudinal beam 1 ; there may be multiple second reinforcing beams 420 , and the multiple second reinforcing beams 420 are arranged along the length direction of the longitudinal beam 1 .
