[0037] At least one longitudinal reinforcing rib 22 is connected between adjacent two transverse reinforcing ribs 21, for example, one, two, three longitudinal reinforcing ribs 22 can be connected between adjacent two transverse reinforcing ribs 21, but the utility model is not limited to this, other number of longitudinal reinforcing ribs 22 can also be connected between adjacent two transverse reinforcing ribs 21, as long as at least one longitudinal reinforcing rib 22 is connected between adjacent two transverse reinforcing ribs 21, which can be reasonably arranged according to the actual stress condition of the rocker beam 100.

[0038] Therefore, the layout and the number of the longitudinal reinforcing ribs 22 and the transverse reinforcing ribs 21 can be flexibly adjusted according to the actual stress condition of the rocker beam 100, all the longitudinal reinforcing ribs 22 and the transverse reinforcing ribs 21 do not need to be cross arranged, the waste of materials can be reduced, the manufacturing cost is reduced, the number of the transverse reinforcing ribs 21 and the longitudinal reinforcing ribs 22 can be reasonably reduced, the structural complexity of the reinforcing structure 20 is reduced, the weight of the rocker beam 100 is reduced under the premise of ensuring the rigidity and safety of the vehicle body, the lightweight design of the vehicle is facilitated, and the manufacturing cost of the whole vehicle is also reduced.

[0039] According to the rocker beam 100 in the embodiment of the utility model, the reinforcing structure 20 is arranged in the cavity 11 and fixedly connected with the rocker beam body 10, the reinforcing structure 20 comprises a plurality of transverse reinforcing ribs 21 and a plurality of longitudinal reinforcing ribs 22, the plurality of transverse reinforcing ribs 21 and the plurality of longitudinal reinforcing ribs 22 cooperate to divide the cavity 11 into a plurality of sub-cavities 111, the plurality of transverse reinforcing ribs 21 are sequentially and spacedly arranged along the height direction of the rocker beam 100, and at least part of the plurality of longitudinal reinforcing ribs 22 are sequentially and spacedly arranged along the width direction of the rocker beam 100, the torsional strength and the bending strength of the rocker beam 100 are effectively enhanced, the rocker beam 100 can better maintain the shape and integrity when facing external force such as side collision, and the rigidity and safety of the vehicle body can be improved.

[0040] According to some embodiments of the utility model, as shown in Figure 1 The plurality of transverse reinforcing ribs 21 can comprise a first transverse reinforcing rib 211, a second transverse reinforcing rib 212 and a third transverse reinforcing rib 213, the second transverse reinforcing rib 212 is located between the first transverse reinforcing rib 211 and the third transverse reinforcing rib 213, and the plurality of longitudinal reinforcing ribs 22 comprises a first longitudinal reinforcing rib 221, and the first longitudinal reinforcing rib 221 is connected between the first transverse reinforcing rib 211 and the second transverse reinforcing rib 212.

[0041] The multiple transverse reinforcing ribs 21 and longitudinal reinforcing ribs 22 provide a multi-level support structure for the rocker beam 100, so that the rocker beam 100 can effectively disperse and transmit stress when subjected to external force, reducing the risk of damage to the rocker beam 100. The first longitudinal reinforcing rib 221 is connected between the first transverse reinforcing rib 211 and the second transverse reinforcing rib 212, providing a multi-level support structure for the rocker beam 100, enhancing the connection strength between the transverse reinforcing ribs 21 and the longitudinal reinforcing ribs 22, making the entire reinforcing structure 20 more stable, and also making the rocker beam 100 more effectively disperse and transmit stress when subjected to impact or extrusion, preventing structural damage and better maintaining shape and integrity.

[0042] According to some embodiments of the present application, as shown in Figure 1 The rocker beam body 10 has a rocker beam top wall 12 and a rocker beam bottom wall 13, the first transverse reinforcing rib 211 is located between the rocker beam top wall 12 and the second transverse reinforcing rib 212, the third transverse reinforcing rib 213 is located between the rocker beam bottom wall 13 and the second transverse reinforcing rib 212, and the multiple longitudinal reinforcing ribs 22 further include a second longitudinal reinforcing rib 222 connected between the third transverse reinforcing rib 213 and the rocker beam bottom wall 13.

[0043] The first transverse reinforcing rib 211, the second transverse reinforcing rib 212 and the third transverse reinforcing rib 213 provide support at different height positions of the rocker beam 100, forming a multi-level structural support system that can effectively resist forces and torques from different directions, enhancing the overall strength and rigidity of the rocker beam 100. The third transverse reinforcing rib 213 is located between the rocker beam bottom wall 13 and the second transverse reinforcing rib 212, providing additional support to the bottom of the rocker beam 100, which helps prevent deformation or damage to the rocker beam 100 when subjected to bottom impact or pressure. The second longitudinal reinforcing rib 222 is connected between the third transverse reinforcing rib 213 and the rocker beam bottom wall 13, further enhancing the support strength of the bottom of the rocker beam 100, helping to disperse the force received at the bottom to the entire rocker beam 100 structure, improving the overall stability of the structure, and helping to reduce the risk of damage or loss of control of the vehicle during driving due to impact on the bottom.

[0044] According to some embodiments of the present application, as shown in Figure 1As shown, the first longitudinal reinforcing rib 221 and the second longitudinal reinforcing rib 222 are arranged opposite along the height direction of the rocker beam 100, which can be explained as that the first longitudinal reinforcing rib 221 and the second longitudinal reinforcing rib 222 are arranged opposite and spaced apart along the height direction of the rocker beam 100, and the first longitudinal reinforcing rib 221 and the second longitudinal reinforcing rib 222 form a multi-level and three-dimensional support structure together with the rocker beam top wall 12, the rocker beam bottom wall 13 and the transverse reinforcing rib 21, which can more effectively resist forces and torques from different directions, thereby enhancing the overall strength and rigidity of the rocker beam 100. And along the height direction of the rocker beam 100, the force transmission path where the first longitudinal reinforcing rib 221 and the second longitudinal reinforcing rib 222 are located can be a non-main force transmission path, and then the first longitudinal reinforcing rib 221 and the second longitudinal reinforcing rib 222 are arranged opposite and spaced apart along the height direction of the rocker beam 100, which can reduce the number of longitudinal reinforcing ribs 22, thereby reducing material waste and reducing manufacturing costs, and also reducing the structural complexity of the reinforcing structure 20, which can reduce the weight of the rocker beam 100 under the premise of ensuring the rigidity and safety of the vehicle body, which is beneficial to the lightweight design of the vehicle.

[0045] According to some embodiments of the present application, as shown in Figure 1 The plurality of longitudinal reinforcing ribs 22 include a third longitudinal reinforcing rib 223, the third longitudinal reinforcing rib 223 and the first longitudinal reinforcing rib 221 are arranged spaced apart along the width direction of the rocker beam 100, and the third longitudinal reinforcing rib 223 is arranged intersecting with the first transverse reinforcing rib 211 and the second transverse reinforcing rib 212.

[0046] The third longitudinal reinforcing rib 223 is arranged intersecting with the first transverse reinforcing rib 211 and the second transverse reinforcing rib 212, and the first longitudinal reinforcing rib 221 is connected between the first transverse reinforcing rib 211 and the second transverse reinforcing rib 212, which together constitute a multi-directional interaction support network, which can more effectively resist forces and torques from different directions, thereby enhancing the integrity and stability of the rocker beam 100, so that the rocker beam 100 can better resist deformation when subjected to external forces, which helps to maintain the geometric shape and dimensional stability of the rocker beam 100 and prolong its service life. And the third longitudinal reinforcing rib 223 is arranged intersecting with the first transverse reinforcing rib 211 and the second transverse reinforcing rib 212, which helps to disperse the stress in the rocker beam 100 to a larger area, reduces the phenomenon of stress concentration, and helps to reduce the maximum stress value of the rocker beam 100 during the stress process, thereby improving its carrying capacity.

[0047] According to some embodiments of the present application, as shown in Figure 1As shown, along the height direction of the rocker beam 100, the third longitudinal reinforcing rib 223 and the third transverse reinforcing rib 213 are staggered, which can avoid stress concentration at a certain position, thereby forming a more uniform and stable support system, reducing the risk of structural failure caused by stress concentration, and improving the overall rigidity of the rocker beam 100. In addition, the staggered third longitudinal reinforcing rib 223 and the third transverse reinforcing rib 213 also facilitate later maintenance and repair, thereby reducing the maintenance cost of the rocker beam 100, and also helping to reduce the structural complexity of the reinforcing structure 20.

[0048] According to some embodiments of the present application, the rocker beam 100 can be a one-piece member, which can reduce the number of connecting members and welds, avoid the decrease in structural strength caused by improper connection or weld quality problems, and effectively absorb and disperse collision energy due to the continuity and integrity of the internal reinforcing structure 20, thereby improving the collision strength of the side of the vehicle door and enhancing the side collision safety performance of the vehicle body. Moreover, the production process of the one-piece member is relatively simple, reducing the assembly and welding process of the parts, thereby improving the production efficiency. As an example of the present application, the rocker beam 100 can be integrally manufactured using lightweight materials such as aluminum alloy, which can reduce the weight of the rocker beam 100 while ensuring the strength and rigidity of the rocker beam 100, thereby helping to reduce the weight of the vehicle, reducing fuel consumption and emissions, and improving fuel economy.

[0049] According to some embodiments of the present application, at least one transverse reinforcing rib 21 is formed with a first inducing notch for inducing deformation of the transverse reinforcing rib 21; and / or

[0050] At least one longitudinal reinforcing rib 22 is formed with a second inducing notch for inducing deformation of the transverse reinforcing rib 21.

[0051] As an example of the present application, at least one transverse reinforcing rib 21 is formed with a first inducing notch for inducing deformation of the transverse reinforcing rib 21, for example, one, two, three or the like number of transverse reinforcing ribs 21 can be formed with the first inducing notch for inducing deformation of the transverse reinforcing rib 21, but the present application is not limited thereto, and other numbers of transverse reinforcing ribs 21 can also be formed with the first inducing notch for inducing deformation of the transverse reinforcing rib 21, as long as at least one transverse reinforcing rib 21 is formed with the first inducing notch for inducing deformation of the transverse reinforcing rib 21.

[0052] As another embodiment of the present application, at least one longitudinal reinforcing rib 22 is formed with a second induction notch for inducing deformation of the transverse reinforcing rib 21, for example, one, two, three or the like number of longitudinal reinforcing ribs 22 can be formed with a second induction notch for inducing deformation of the transverse reinforcing rib 21, but the present application is not limited thereto, and other number of longitudinal reinforcing ribs 22 can be formed with a second induction notch for inducing deformation of the transverse reinforcing rib 21, as long as at least one longitudinal reinforcing rib 22 is formed with a second induction notch for inducing deformation of the transverse reinforcing rib 21.

[0053] As another embodiment of the present application, at least one transverse reinforcing rib 21 is formed with a first induction notch for inducing deformation of the transverse reinforcing rib 21, and at least one longitudinal reinforcing rib 22 is formed with a second induction notch for inducing deformation of the transverse reinforcing rib 21.

[0054] By forming the transverse reinforcing rib 21 with a first induction notch for inducing deformation of the transverse reinforcing rib 21, and forming the longitudinal reinforcing rib 22 with a second induction notch for inducing deformation of the transverse reinforcing rib 21, the transverse reinforcing rib 21 and the longitudinal reinforcing rib 22 can be guided to deform in a predetermined direction and manner, which helps the reinforcing structure 20 to more effectively absorb and disperse energy when subjected to external force, thereby improving the overall stability and resistance of the reinforcing structure 20.

[0055] It can be explained that the design of the first induction notch and the second induction notch needs to comprehensively evaluate the overall performance of the rocker beam 100 structure, and accurately control the depth and position of the first induction notch and the second induction notch to ensure the stability and reliability of the rocker beam 100.

[0056] As an embodiment of the present application, as shown in Figure 1 The angle between the rocker beam top wall 12 and the third longitudinal reinforcing rib 223 can be α, and the angle α can be 77°, so that the rocker beam top wall 12 is inclined towards the seat cross beam of the vehicle, which is conducive to the rocker beam 100 transmitting the collision force to the seat cross beam of the vehicle, helps to disperse the collision energy, can reduce the deformation of the rocker beam 100 and its surrounding structure, and helps to maintain the overall structural stability of the vehicle.

[0057] The angle between the first transverse reinforcing rib 211 and the third longitudinal reinforcing rib 223 can be β, and the angle β can be 90°, so that the first transverse reinforcing rib 211 is horizontally aligned with the seat cross beam of the vehicle, which can improve the force transmission efficiency of the rocker beam 100, so that the collision force can be more directly transmitted to the seat cross beam through the rocker beam 100, reducing the loss and dispersion of force in the transmission process, thereby improving the force transmission efficiency, reducing the deformation of the rocker beam 100 and its surrounding structure, and helping to maintain the overall structural stability of the vehicle, reducing potential safety hazards caused by deformation.

[0058] The threshold beam body 10 can include a first side wall 30 and a second side wall 31, an included angle a can be formed between the second transverse reinforcing rib 212 and the first side wall 30, the included angle a can be 102°, an included angle b can be formed between the third transverse reinforcing rib 213 and the first side wall 30, the included angle b can be 110°, which is beneficial to the purpose of achieving collapse of the threshold beam 100 in the initial stage of collision, so that the threshold beam 100 can more effectively absorb and disperse collision energy, ensuring the structural stability of the threshold beam 100 in daily use. An included angle c can be formed between the threshold beam bottom wall 13 and the second side wall 31, the included angle c can be 110.5°, which is beneficial to the threshold beam 100 to transmit the collision force received to the seat cross beam of the vehicle, helps to disperse the collision energy, can reduce the deformation of the threshold beam 100 and its surrounding structure, and helps to maintain the overall structural stability of the vehicle.

[0059] The part of the second transverse reinforcing rib 212 close to the second side wall 31 can protrude towards the first transverse reinforcing rib 211 to form an included angle d, the included angle d can be 158°, which is beneficial to the part of the second transverse reinforcing rib 212 close to the second side wall 31 to collapse, thereby more effectively absorbing and dispersing collision energy, ensuring the structural stability of the threshold beam 100 in daily use. It can be explained that the layout (such as the included angle value) between the threshold beam 100 and the reinforcing structure 20 can be reasonably set according to the actual stress condition of the threshold beam 100, thereby being able to ensure that the threshold beam 100 will neither be excessively deformed nor be damaged due to excessive stress when bearing load.

[0060] Further, as an example of the present application, the wall thickness of the threshold beam top wall 12 can be 2.7-2.9mm, for example: the wall thickness of the threshold beam top wall 12 can be 2.7mm, 2.8mm, etc. The present application takes the wall thickness of the threshold beam top wall 12 as 2.8mm as an example for description. The wall thickness of the first transverse reinforcing rib 211 can be 2.7-2.9mm, for example: the wall thickness of the first transverse reinforcing rib 211 can be 2.7mm, 2.8mm, etc. The present application takes the wall thickness of the first transverse reinforcing rib 211 as 2.8mm as an example for description. The wall thickness of the second transverse reinforcing rib 212 can be 2.2-2.4mm, for example: the wall thickness of the second transverse reinforcing rib 212 can be 2.2mm, 2.3mm, etc. The present application takes the wall thickness of the second transverse reinforcing rib 212 as 2.3mm as an example for description. The wall thickness of the part of the threshold beam bottom wall 13 adjacent to the second side wall 31 can be 2.1-2.3mm, for example: the wall thickness of the part of the threshold beam bottom wall 13 adjacent to the second side wall 31 can be 2.1mm, 2.2mm, etc. The present application takes the wall thickness of the part of the threshold beam bottom wall 13 adjacent to the second side wall 31 as 2.2mm as an example for description. The wall thickness of the threshold beam 100 and the reinforcing structure 20 can be reasonably set according to the actual stress of the threshold beam 100, so as to ensure that the threshold beam 100 will not be deformed too much or damaged due to excessive stress when bearing load.

[0061] The vehicle body according to the embodiment of the present application comprises the threshold beam 100 of the above-mentioned embodiment, which effectively enhances the torsional strength and bending strength of the threshold beam 100, so that the threshold beam 100 can better maintain the shape and integrity when facing external forces such as side collision, thereby improving the rigidity and safety of the vehicle body, reducing the weight of the threshold beam 100 under the premise of ensuring the rigidity and safety of the vehicle body, which is beneficial to the lightweight design of the vehicle and can also reduce the manufacturing cost of the vehicle.
