[0032] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0033] The auxiliary beam according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0034] like Figure 1-Figure 4 As shown, the auxiliary beam 1 according to the embodiment of the present invention includes a front connecting plate portion 100 , a rear connecting plate portion 200 and a top plate portion 300 .

[0035] The front connecting plate portion 100 and the rear connecting plate portion 200 are vertically arranged and spaced apart from each other in the front and rear directions. Both ends of the front connecting plate portion 100 and the rear connecting plate portion 200 are suitable for being mounted on the vehicle body suspension bracket 10. A avoidance space 201 is formed in the middle of the lower edge of the front connecting plate portion 100 and the rear connecting plate portion 200. The top plate portion 300 is connected to the upper edge of the front connecting plate portion 100 and the upper edge of the rear connecting plate portion 200. The top plate portion 300 is configured with a weight-reducing hole 301, which extends along the length direction of the top plate portion 300.

[0036] According to the auxiliary cross beam 1 of the embodiment of the utility model, the structural arrangement of the weight-reducing holes 301 can reduce the overall weight of the auxiliary cross beam 1 to a certain extent. By forming the weight-reducing holes 301 on the top plate 300, the amount of material used is reduced, and the lightweight design level of the vehicle body components is improved. At the same time, reducing the weight of the auxiliary cross beam 1 can reduce the dead weight of the entire vehicle, reduce energy consumption during the use of the vehicle, and help reduce the vehicle's fuel consumption and reduce exhaust emissions, thereby achieving the purpose of energy conservation and emission reduction.

[0037] In addition, the middle part of the front connecting plate 100 and the rear connecting plate 200 forms an avoidance space 201, which can avoid the retarder pipeline during the operation of the vehicle, avoid collision between various components, and improve the stability and reliability of the overall structure of the vehicle. At the same time, the avoidance space 201 can also reduce the weight of the auxiliary cross beam 1 itself, reduce the use of materials, and improve the lightweight degree of the auxiliary cross beam 1.

[0038] Therefore, the auxiliary cross beam 1 according to the embodiment of the utility model has the advantages of achieving a lightweight structure of the entire vehicle and energy saving and emission reduction.

[0039] In some specific embodiments of the present invention, Figure 2 and Figure 4As shown, the weight-reducing hole 301 is constructed as an oblong hole, and the weight-reducing hole 301 is located in the middle of the width direction of the top plate 300. The weight-reducing hole 301 with an oblong hole structure can effectively reduce the weight of the auxiliary cross beam 1, thereby reducing the total weight of the vehicle, which helps to improve the fuel economy of the vehicle and conforms to the trend of lightweight in modern automobile engineering design. More importantly, the oblong hole is set in the middle of the top plate 300, which can improve the force distribution of the auxiliary cross beam 1 to a certain extent, reduce local force, reduce the degree of stress concentration, and help improve the stability and durability of the structure.

[0040] In some specific embodiments of the present invention, Figure 4 As shown, the lower edge of the front connecting plate portion 100 is configured with a front reinforcing flange 110 folded forward, and the front reinforcing flange 110 extends continuously along the lower edge of the front connecting plate portion 100. The lower edge of the rear connecting plate portion 200 is configured with a rear reinforcing flange 210 folded backward, and the rear reinforcing flange 210 extends continuously along the lower edge of the rear connecting plate portion. The front reinforcing flange 110 and the rear reinforcing flange 210 extend in opposite directions, and extend along the directions in which the lengths of the front connecting plate portion 100 and the rear connecting plate portion 200 extend, respectively.

[0041] The front reinforcement flange 110 and the rear reinforcement flange 210 can effectively increase the strength of the front connecting plate 100 and the rear connecting plate 200 in the longitudinal direction, and improve the bending and torsion resistance of the entire auxiliary cross beam 1. Through the structure of the front reinforcement flange 110 and the rear reinforcement flange 210, the force bearing area can be increased, the stress is distributed, the local force concentration is effectively reduced, and the bearing capacity and stability of the structure are improved.

[0042] At the same time, the front reinforcing flange 110 and the rear reinforcing flange 210 can reduce the vibration and deformation of the front connecting plate 100 and the rear connecting plate 200 , reduce the stress concentration, extend the service life of the auxiliary beam 1 , and improve the durability of the overall structure of the auxiliary beam 1 .

[0043] In some specific embodiments of the present invention, Figure 2 and Figure 4 As shown, weight-reducing notches 302 are formed at both ends of the top plate 300, and the weight-reducing notches 302 are located in the middle of the width direction of the top plate 300. The weight-reducing notches 302 are arc-shaped, and both sides extend in the length direction of the top plate 300 respectively.

[0044] By providing weight-reducing notches 302 at both ends of the top plate 300 of the auxiliary cross beam 1, the weight of the auxiliary cross beam 1 can be effectively reduced. The structure of the weight-reducing notches 302 can reduce the amount of material used and the weight of the overall structure of the auxiliary cross beam 1 while ensuring the structural strength and rigidity of the auxiliary cross beam 1, which helps to improve the fuel economy and reduce emissions of the vehicle, and also improve the vehicle's dynamics and the response of the suspension system.

[0045] In some specific embodiments of the present invention, Figure 4 As shown, the width of the weight-reducing notch 302 along the front-to-back direction gradually increases toward the two ends of the auxiliary cross beam 1. The structure in which the weight-reducing notch 302 gradually increases along the front-to-back direction can better optimize the distribution of the auxiliary cross beam 1 when it is subjected to force. The weight-reducing notch 302 with gradually increasing width can more effectively reduce the stress concentration phenomenon at the end of the auxiliary cross beam 1, disperse the force, and improve the stability and durability of the structure.

[0046] In addition, the vehicle body suspension bracket 10 is installed on both sides of the auxiliary cross beam 1, and the weight-reducing notch 302 with gradually increasing width can adapt to the changes in the structure of the vehicle body suspension bracket 10 itself, facilitate the installation process, and improve the installation efficiency.

[0047] In some specific embodiments of the present invention, Figure 2 As shown, the middle portion of the top plate portion 300 in the longitudinal direction extends horizontally, and both ends of the top plate portion 300 extend obliquely downward.

[0048] The structure extending downward obliquely can increase the bending rigidity and stress-bearing performance of the auxiliary crossbeam 1. By extending the two ends of the top plate 300 obliquely downward, the lateral rigidity at the edge of the top plate 300 can be effectively increased, the bearing capacity and durability of the overall structure can be improved, and the stress in the middle and both ends of the top plate 300 can be balanced, stress concentration can be reduced, and the stability and reliability of the structure can be improved.

[0049] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the front connecting plate portion 100 and the rear connecting plate portion 200 are both configured with mounting holes 101 corresponding to each other, and the mounting holes 101 are suitable for mounting on the vehicle body suspension bracket 10. The mounting holes 101 can be located in the middle of the front connecting plate portion 100 and the rear connecting plate portion 200, and are evenly distributed on the top of the avoidance space 200. The arranged mounting holes 101 provide fixing points, and the auxiliary cross beam 1 can be connected to the vehicle body suspension bracket 10, so as to ensure that the connection between the auxiliary cross beam 1 and the vehicle body suspension bracket 10 is firm and reliable, thereby effectively supporting the vehicle structure and transferring the load.

[0050] Likewise, the position of the mounting hole 101 can play a positioning role, ensuring the correct position and direction of the auxiliary cross beam 1 during the installation process. Accurate positioning can improve the installation efficiency and ensure the accuracy and stability of the entire vehicle body structure.

[0051] In some specific embodiments of the present invention, Figure 2 and Figure 3As shown, there are multiple mounting holes 101, the mounting holes 101 near the two ends of the auxiliary beam 1 are arranged vertically, and the mounting holes 101 near the middle of the auxiliary beam 1 are arranged horizontally.

[0052] The horizontally arranged mounting holes 101 near the middle of the auxiliary cross beam 1 help to release stress in the middle area. Under the action of external loads, the stress generated on the vehicle body suspension bracket 10 can be more easily transferred to other supporting structures through the auxiliary cross beam 1 through these horizontally arranged mounting holes 101, thereby achieving stress release and dispersion.

[0053] In some specific embodiments of the present invention, the thickness of the front connecting plate portion 100, the top plate portion 300 and the rear connecting plate portion 200 are all 4mm to 6mm. The auxiliary crossbeam 1 of the embodiment of the present invention is thinner by about 1mm, the mass is reduced by about 0.65KG, and the weight is reduced by about 6.7% compared with the auxiliary crossbeam in the prior art. By reducing the wall thickness of each part of the auxiliary crossbeam 1, the weight of the auxiliary crossbeam 1 can be effectively reduced while ensuring that it has sufficient structural strength, thereby reducing the weight of the overall structure of the vehicle. While reducing the use of materials and saving costs, it can improve fuel economy and handling, and it is also beneficial to reduce the stress burden on other components.

[0054] In addition, proper control of the wall thickness can optimize the structural design, making the auxiliary cross beam 1 lighter and more delicate while ensuring sufficient strength and rigidity. Structural optimization helps to improve the force performance and overall stability of the auxiliary cross beam 1 and enhance the safety of the vehicle.

[0056] According to the vehicle of the embodiment of the utility model, Figure 1 As shown, it includes the auxiliary cross beam 1, the longitudinal beam 20 and the vehicle body suspension bracket 20 according to the above embodiment of the utility model. The vehicle body suspension bracket 10 is installed on the longitudinal beam 20. Both ends of the auxiliary cross beam 1 are installed on the vehicle body suspension bracket 20.

[0057] For example, the vehicle body suspension bracket 10 is fixed on both sides of the longitudinal beam 20, the front connecting plate portion 100 and the rear connecting plate portion 200 are fixed on the vehicle body suspension bracket 10 and span across both sides of the longitudinal beam 20, the height of the middle protrusion of the front connecting plate portion 100 and the rear connecting plate portion 200 is greater than the height of the protrusions on both sides and the width of the edges on both sides is greater than the width of the middle connecting portion.
