However, the auxiliary crossbeams in the related art are bulky in overall structural design and large in size, with vertically arranged mounting holes and wide width. For the vehicle as a whole that needs to be installed with the auxiliary crossbeams, the weight of the parts is too heavy, and the stability of the assembly needs to be improved.

[0033] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0034] The auxiliary beam 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 4 As shown, the auxiliary cross beam 1 according to the embodiment of the utility model includes a left suspension bracket 100 , a right suspension bracket 200 , a front cross beam 300 and a rear cross beam 400 .

[0036] The left suspension bracket 100 is mounted on the left longitudinal beam 10, and the right suspension bracket 200 is mounted on the right longitudinal beam 20. The front cross beam 300 is constructed as a stamping sheet and is mounted on the front side of the left suspension bracket 100 and the right suspension bracket 200. The front cross beam 300 spans over the left longitudinal beam 10 and the right longitudinal beam 20, and the height of the middle part of the length direction of the front cross beam 300 is higher than the height of the two ends. The rear cross beam 400 is constructed as a stamping sheet and is mounted on the rear side of the left suspension bracket 100 and the right suspension bracket 200. The rear cross beam 400 spans over the left longitudinal beam 10 and the right longitudinal beam 20. The front cross beam 300 and the rear cross beam 400 are spaced apart from each other in the front and rear directions, and the height of the middle part of the length direction of the rear cross beam 400 is higher than the height of the two ends.

[0037] For example, the left suspension bracket 100 and the right suspension bracket 200 are symmetrically arranged on both sides of the left longitudinal beam 10 and the right longitudinal beam 20, and the front cross beam 300 and the right cross beam 400 are both located between the left suspension bracket 100 and the right suspension bracket 200. One side of the left suspension bracket 100 and the right suspension bracket 200 is connected to the left longitudinal beam 10 and the right longitudinal beam 20 by fasteners, and the opposite side is connected to the rear suspension support bracket 30 of the vehicle body, and the middle part is connected to the front cross beam 300 and the rear cross beam 400. The front cross beam 300 and the rear cross beam 400 are both constructed in an arc shape with low ends and high middle, and the two ends are irregular arc shapes.

[0038] According to the auxiliary crossbeam 1 of the embodiment of the utility model, compared with the traditional structure in which the auxiliary crossbeam 1 is installed below the frame longitudinal beam, the auxiliary crossbeam 1 of this embodiment is installed above the frame longitudinal beam and connected to the rear suspension of the cab. Through the new auxiliary crossbeam 1 structure, the front crossbeam 300 and the rear crossbeam 400 are constructed as a stamping sheet structure, which reduces the amount of material used while ensuring the structural strength of the auxiliary crossbeam 1 itself, thereby reducing the overall structural weight of the auxiliary crossbeam 1 and achieving a lightweight structure. In addition, the height difference between the height of the middle part of the front crossbeam 300 and the height of the rear crossbeam 400 at both ends in the length direction forms a height difference, which can achieve a reasonable force distribution of the auxiliary crossbeam 1 in the overall structure. When the auxiliary crossbeam 1 is loaded, the structure with a higher height in the middle part can bear a larger load, thereby improving the stability and bending bearing capacity of the structure.

[0039] Therefore, the auxiliary cross beam 1 according to the embodiment of the utility model has the advantages of high lightness and good structural stability.

[0040] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the width directions of the front cross beam 300 and the rear cross beam 400 are both vertically extended, the upper edge of the front cross beam 300 is configured with a front upper flange 301, and the lower edge of the front cross beam 300 is configured with a front lower flange 302, and the front upper flange 301 and the front lower flange 302 face the same side. The upper edge of the rear cross beam 400 is configured with a rear upper flange 401, and the lower edge of the rear cross beam 400 is configured with a rear lower flange 402, and the rear upper flange 401 and the rear lower flange 402 face the same side.

[0041] The front upper flange 301 and the front lower flange 302 of the front cross beam 300 are bent outwards in a direction away from each other, and similarly, the rear upper flange 401 and the rear lower flange 402 of the rear cross beam 400 are bent outwards in a direction away from each other, and the front cross beam 300 and the rear cross beam 400 are strengthened in the thickness direction, which can provide additional support when bearing vertical loads, prevent the front cross beam 300 and the rear cross beam 400 from bending or deformation, and ensure the stability of the structure. At the same time, the front upper flange 301 and the front lower flange 302, the rear upper flange 401 and the rear lower flange 402 can respectively make the shapes of the front cross beam 300 and the rear cross beam 400 more three-dimensional, and play a better strengthening role.

[0042] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the front upper flange 301 and the front lower flange 302 both extend forward, and the rear upper flange 401 and the rear lower flange 402 both extend backward.

[0043] By extending the front upper flange 301 and the front lower flange 302 forward, and the rear upper flange 401 and the rear lower flange 402 backward, the overall structure of the front cross beam 300 and the rear cross beam 400 is made more solid and stable. The flange structure extending forward can increase the bearing capacity of the front cross beam 300 and the rear cross beam 400, so that it can better support the lateral load and the vertical load, thereby improving the safety and stability of the structure. At the same time, the structure in which the front upper flange 301, the front lower flange 302 and the rear upper flange 401 and the rear lower flange 402 extend in opposite directions can also optimize the overall structural layout, so that the load of the front cross beam 300 and the rear cross beam 400 in all directions is evenly distributed, reducing the possibility of local stress concentration and extending the service life of the auxiliary cross beam.

[0044] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the front crossbeam 300 and the rear crossbeam 400 are symmetrically arranged along the front-to-back direction. The symmetrical structure can balance the loads in all directions on the front crossbeam 300 and the rear crossbeam 400, so that the entire structure is more stable when bearing the load. Through the symmetrical arrangement in the front-to-back direction, the front crossbeam 300 and the rear crossbeam 400 can evenly distribute the load, reduce the risk of local stress concentration, and improve the bearing capacity of the overall structure. At the same time, the symmetrical arrangement of the front crossbeam 300 and the rear crossbeam 400 can make the structure less likely to tilt or deform when subjected to external forces, maintain overall balance, and improve endurance and wind resistance. In addition, symmetrical structures usually have a more balanced and beautiful appearance. The symmetrical arrangement in the front-to-back direction can make the auxiliary crossbeam 1 look more symmetrical and coordinated as a whole, adding beauty to the overall structure.

[0045] In some specific embodiments of the present invention, Figure 2-Figure 4As shown, the front upper flange 301 and the front lower flange 302 of the front cross beam 300 are both arc transitions, and the rear upper flange 401 and the rear lower flange 402 of the rear cross beam 400 are both arc transitions. The arc transition can effectively reduce the stress concentration phenomenon at the connection between the front cross beam 300 and the rear cross beam 400 and the flange. Compared with right-angle transition or other sharp-angle transition, the arc transition can make the force more uniform, reduce the possibility of local stress concentration, thereby improving the overall strength and stability of the structure, and can reduce the stress concentration generated by the structure when it is subjected to external loads, reduce the risk of deformation or rupture of the auxiliary cross beam 1, improve the bearing capacity and durability of the auxiliary cross beam 1, and extend the service life of the auxiliary cross beam 1.

[0046] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the front cross beam 300 and the rear cross beam 400 each include a left oblique extension portion 310, a right oblique extension portion 320 and a horizontal extension portion 330 along the length direction. The left oblique extension portion 310 is mounted on the left suspension bracket 100 and extends obliquely upward in a direction away from the left suspension bracket 100. The right oblique extension portion 320 is mounted on the right suspension bracket 200 and extends obliquely upward in a direction away from the right suspension bracket 200. The horizontal extension portion 330 extends horizontally, and the two ends of the horizontal extension portion 330 are respectively connected to the left oblique extension portion 310 and the right oblique extension portion 320.

[0047] The left inclined extension part 310 and the right inclined extension part 320 are symmetrical structures relative to the horizontal extension part 330, and extend in the left and right directions respectively. By installing the left inclined extension part 310 and the right inclined extension part 320 on both sides of the horizontal extension part 330, the forces on the left and right sides of the front cross beam 300 and the rear cross beam 400 can be balanced and supported, so that the overall force of the cross beam is more uniform, ensuring the balance and stability of the structure, effectively sharing the load, and improving the bearing capacity.

[0048] At the same time, the arrangement of the left inclined extension part 310 and the right inclined extension part 320 makes the front cross beam 300 and the rear cross beam 400 more evenly stressed, reduces the risk of local stress concentration, and prolongs the service life of the front cross beam 300 and the rear cross beam 400. The horizontal extension part 330 connects the left and right parts, making the entire structural layout more reasonable, which is conducive to optimizing the overall stability of the auxiliary cross beam 1 structure.

[0049] In some specific embodiments of the present invention, Figure 2-Figure 4As shown, the vertical dimensions of the left inclined extension portion 310 and the right inclined extension portion 320 are both larger than the vertical dimensions of the horizontal extension portion 330. The larger vertical dimensions of the left inclined extension portion 310 and the right inclined extension portion 320 can improve the overall stability and load-bearing capacity of the auxiliary beam 1 and reduce the risk of deformation or damage of the structure due to excessive stress. By increasing the size of the inclined portion, the safety factor of the auxiliary beam 1 when subjected to force can be effectively improved, reducing the occurrence of accidents.

[0050] In addition, the increased size of the inclined portion can increase the load-bearing capacity of the auxiliary beam 1, improve the force distribution of the structure, and make the auxiliary beam 1 more balanced and stable as a whole, so that it has a higher load-bearing capacity and better durability when subjected to external forces.

[0051] In some specific embodiments of the present utility model, the connection between the left inclined extension 310 and the horizontal extension 330 is an arc transition. The connection between the right inclined extension 320 and the horizontal extension 330 is an arc transition. The arc transition can achieve a smooth transition at the connection, reduce the sudden change and angle change at the connection, and help reduce stress concentration. Such a structure can make the auxiliary beam 1 more evenly distributed, reduce the risk of local stress concentration, and improve the stability of the overall structure. At the same time, the arc transition structure can make the connection more uniform and smooth, which helps to improve the overall strength of the structure. Compared with sharp-angle connections or right-angle connections, the arc transition design can reduce stress concentration at the connection, reduce the possibility of cracks and deformation, and improve the compressive strength of the overall structure of the auxiliary beam 1.

[0052] In some specific embodiments of the present invention, Figure 2-Figure 4 As shown, the upper parts of the two ends of the front cross beam 300 are configured with front upper mounting holes 303 and the lower parts are configured with front lower mounting holes 304, and the distance between the front upper mounting holes 303 at the two ends is smaller than the distance between the front lower mounting holes 304 at the two ends. The upper parts of the two ends of the rear cross beam 400 are configured with rear upper mounting holes 403 and the lower parts are configured with rear lower mounting holes 404, and the distance between the rear upper mounting holes 403 at the two ends is smaller than the distance between the rear lower mounting holes 404 at the two ends.

[0053] The staggered distribution of the front upper mounting hole 303, the front lower mounting hole 304, the rear upper mounting hole 403, and the rear lower mounting hole 404 can achieve a higher fit. By adjusting the distance and mounting position between the mounting holes, the connection between the front crossbeam 300 and the rear crossbeam 400 and other components is more accurate and the fit is higher. This can effectively reduce the looseness and swing between the structures and improve the stability and tightness of the connection.

[0054] At the same time, the structure of multiple mounting holes can increase the connection strength between the front crossbeam 300 and the rear crossbeam 400 and other structures. By distributing the mounting holes in the upper and lower structures, the role of multiple connection points is achieved. This can increase the tightness and firmness of the connection and improve the overall load-bearing capacity and durability of the crossbeam.
