[0032] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0033] Reference below Figure 1-Figure 4 A cross member 100 of a vehicle frame according to an embodiment of the present invention is described.

[0034] like Figure 1 As shown, the crossbeam 100 of the frame according to the embodiment of the first aspect of the utility model includes: a first sub-crossbeam 10 and a second sub-crossbeam 20, the end of the first sub-crossbeam 10 is provided with a first mounting portion 11, the end of the second sub-crossbeam 20 is provided with a second mounting portion 21, the second sub-crossbeam 20 and the first sub-crossbeam 10 are arranged at intervals in the longitudinal direction of the frame 200, the second sub-crossbeam 20 and the first sub-crossbeam 10 are both plate beams, and an installation space 30 that passes through the frame 200 in the vertical direction is formed between the second sub-crossbeam 20 and the first sub-crossbeam 10, so that a tool can be vertically extended into the installation space 30 to install the first mounting portion 11 and the second mounting portion 21.

[0035] Specifically, the crossbeam of a traditional frame is an integrated structure, and the cross-section of the crossbeam near the installation position is U-shaped. When the crossbeam is installed on the longitudinal beam by bolts and nuts, the nuts are located inside the U-shaped structure. The internal installation space is small, which is not convenient for tightening with tools such as wrenches. Similarly, it is not convenient for disassembly with tools such as wrenches, resulting in problems such as unstable installation and difficult maintenance and disassembly.

[0036] Therefore, the crossbeam 100 of the frame is mainly composed of a first sub-crossbeam 10 and a second sub-crossbeam 20. The setting of the first mounting portion 11 at the end of the first sub-crossbeam 10 can facilitate the installation of the first sub-crossbeam 10 on the longitudinal beam 60, and the setting of the second mounting portion 21 at the end of the second sub-crossbeam 20 can facilitate the installation of the second sub-crossbeam 20 on the longitudinal beam 60.

[0037] Furthermore, the second sub-beam 20 and the first sub-beam 10 are arranged at a longitudinal interval on the frame 200, so that the second sub-beam 20 and the first sub-beam 10 are independent of each other. When one of the second sub-beam 20 and the first sub-beam 10 is damaged, the second sub-beam 20 and the first sub-beam 10 can be easily replaced, thereby improving the utilization rate of the first sub-beam 10 and the second sub-beam 20.

[0038] Among them, the second sub-beam 20 and the first sub-beam 10 are both plate beams, which can increase the distance between the second sub-beam 20 and the first sub-beam 10 in the longitudinal direction of the frame 200, thereby increasing the space area between the second sub-beam 20 and the first sub-beam 10, which can facilitate the entry of tools.

[0039] In addition, the second sub-cross beam 20 and the first sub-cross beam 10 form a through installation space 30 in the vertical direction of the frame 200, where the vertical direction is the up and down direction. In this way, the through installation space 30 can form an unobstructed installation space 30, which can facilitate tools such as wrenches to vertically extend into the installation space 30 to install the first installation part 11 and the second installation part 21, and also facilitate tools to vertically extend into the installation space 30 to disassemble the first installation part 11 and the second installation part 21, thereby increasing the speed of installation and disassembly of the cross beam of the frame 200.

[0040] Therefore, the crossbeam 100 of the frame can facilitate the installation and removal of the first installation portion 11 and the second installation portion 21 by extending the tool vertically into the installation space 30 , and can also facilitate the replacement of the second sub-crossbeam 20 and the first sub-crossbeam 10 .

[0041] According to some embodiments of the present invention, Figure 2 and Figure 3 As shown, at least one of the first sub-beam 10 and the second sub-beam 20 includes: a main board 40 and a bending plate 41, the bending plate 41 is respectively connected to the two ends of the main board 40, and the bending plate 41 is bent relative to the main board 40, and the bending plate 41 is provided with a first mounting portion 11 or a second mounting portion 21.

[0042] Among them, the bending plates 41 at both ends of the main board 40 are bent relative to the main board 40, and the first sub-beam 10 and the second sub-beam 20 are both U-shaped as a whole. The setting of the first mounting portion 11 on the bending plate 41 can facilitate the installation and fixation of the first sub-beam 10, and the setting of the second mounting portion 21 on the bending plate 41 can facilitate the installation and fixation of the second sub-beam 20.

[0043] According to some embodiments of the present invention, Figure 3 As shown, at least one of the first sub-crossbeam 10 and the second sub-crossbeam 20 further includes a reinforcing flange 42 , and the reinforcing flange 42 is at least disposed on one vertical side edge of the main board 40 .

[0044] Among them, the reinforcing flange 42 is bent relative to the main board 40 in the vertical direction. When the reinforcing flange 42 is set on the first sub-beam 10, the bent reinforcing flange 42 can increase the stiffness and strength of the first sub-beam 10. When the reinforcing flange 42 is set on the second sub-beam 20, the bent reinforcing flange 42 can increase the stiffness and strength of the second sub-beam 20. When the first sub-beam 10 and the second sub-beam 20 are both provided with the reinforcing flange 42, the stiffness and strength of the first sub-beam 10 and the second sub-beam 20 can be increased, thereby improving the bearing capacity of the beam 100 of the overall frame.

[0045] Furthermore, the reinforcing flange 42 can increase the torsion resistance of the first sub-beam 10 and the second sub-beam 20, making them more stable when subjected to torsion or lateral force. In addition, the reinforcing flange 42 can reduce the stress concentration at the edges of the first sub-beam 10 and the second sub-beam 20, thereby reducing the risk of cracking at the edges of the first sub-beam 10 and the second sub-beam 20.

[0046] According to the specific embodiment of the utility model, Figure 3 As shown, the reinforcing flange 42 includes: an upper reinforcing flange 421 and / or a lower reinforcing flange 422, the upper reinforcing flange 421 is arranged at the vertical upper side edge of the main board 40, and the upper reinforcing flange 421 also extends to the vertical upper side edge of the bending plate 41, and the lower reinforcing flange 422 is arranged at the vertical lower side edge of the main board 40.

[0047] Specifically, the first sub-crossbeam 10 may be provided with only the upper reinforcing flange 421, or only the lower reinforcing flange 422, or both the upper reinforcing flange 421 and the lower reinforcing flange 422 may be provided on the first sub-crossbeam 10. In addition, the second sub-crossbeam 20 may be provided with only the upper reinforcing flange 421, or only the lower reinforcing flange 422, or both the upper reinforcing flange 421 and the lower reinforcing flange 422 may be provided on the second sub-crossbeam 20. The upper reinforcing flange 421 is provided on the vertical upper side edge of the main board 40, and the upper reinforcing flange 421 is bent relative to the main board 40, so that the strength and rigidity of the upper side edge of the first sub-crossbeam 10 or the upper side edge of the second sub-crossbeam 20 can be increased. Furthermore, the upper reinforcing flange 421 also extends to the vertical upper side edge of the bending plate 41, so that the strength and rigidity of the upper side edge of the bending plate 41 can be increased.

[0048] In addition, the lower reinforcing flange 422 is disposed at the vertical lower edge of the main board 40 , and the lower reinforcing flange 422 is bent relative to the main board 40 , which can increase the strength and rigidity of the lower edge of the main board 40 .

[0049] According to some embodiments of the present invention, Figure 2 and Figure 3 As shown, the reinforcement flange 42 is bent toward a side adjacent to the installation space 30 .

[0050] Among them, the reinforcing flange 42 is bent toward one side adjacent to the installation space 30, so that the installation space 30 can be utilized, thereby making its structure more compact, avoiding interference with other components or equipment, ensuring the effective use of the installation space 30, and reducing unnecessary collisions and conflicts.

[0051] According to some embodiments of the present invention, Figure 3 and Figure 4 As shown, at least one of the first sub-beam 10 and the second sub-beam 20 includes a reinforcing plate 50 , and the reinforcing plate 50 is disposed on the bending plate 41 .

[0052] Among them, the reinforcing plate 50 is arranged on the bending plate 41 in the first sub-beam 10 or the second sub-beam 20, and the reinforcing plate 50 is respectively arranged at both ends of the first sub-beam 10 or the second sub-beam 20, and the reinforcing plate 50 is connected to the bending plate 41. In this way, the strength and rigidity of the first sub-beam 10 or the second sub-beam 20 at the bending plate 41 can be increased.

[0053] In addition, the reinforcing plate 50 is also correspondingly disposed on the first mounting portion 11 or the second mounting portion 21 , so as to further increase the mounting strength of the first mounting portion 11 or the second mounting portion 21 .

[0054] According to the specific embodiment of the utility model, Figure 2 and Figure 4 As shown, the reinforcing plate 50 is located on the side of the bending plate 41 facing the installation space 30 .

[0055] Specifically, the bent plate 41 can provide an installation space 30 for the installation of the reinforcing plate 50, and the bent plate 41 and the reinforcing flange 42 are connected to form an accommodation space, so that the reinforcing plate 50 can be placed easily. Further, the reinforcing plate 50 is arranged on the side facing the installation space 30, so that the reinforcing plate 50 can not only be arranged using the installation space 30, but also increase the strength and rigidity of the first installation portion 11 and the second installation portion 21, so that the first sub-cross beam 10 can be installed more firmly, and the second sub-cross beam 20 can be installed more firmly, and the first installation portion 11 and the second installation portion 21 can be prevented from being torn, so that the reliability and safety of the cross beam 100 of the frame can be improved.

[0056] According to some embodiments of the present invention, Figure 2 and Figure 4 As shown, the first mounting portion 11 and the second mounting portion 21 are each provided with at least two mounting holes 12 .

[0057] Among them, the bending plate 41 and the reinforcing plate 50 in the first mounting part 11 and the second mounting part 21 are both provided with a plurality of mounting holes 12. The setting of the plurality of mounting holes 12 can prevent the installation of the first sub-beam 10 from being loosened, and can also prevent the installation of the second sub-beam 20 from being loosened, thereby making the installation of the first sub-beam 10 and the second sub-beam 20 more stable and firm.
