[0002] Because of different factors such as wheelbase, configuration and shape, the overall vehicle weight of the same platform vehicle is not consistent, and the requirements of the door sill beam section are different when responding to the collision demand. The longer the wheelbase and the heavier the overall vehicle, the higher the strength requirement of the door sill beam.

[0003] The aluminum door sill beam is usually extruded and formed, and the section is a fixed structure. If the long wheelbase and large mass vehicle is met, the collision demand that the door sill beam section needs to meet is inevitably more complex, and the weight is heavier. For the lighter vehicle, there is no need for excessive performance. If the door sill beam is designed according to the lighter vehicle, the attribute requirements of the heavier vehicle cannot be met, and the applicable range of the door sill beam is limited.

[0029] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0030] Example 1

[0031] This embodiment provides a door sill beam for use in vehicles. The door sill beam is a split structure, comprising a first beam 1 and a second beam 2. The first beam 1 maintains its main shape, thus achieving structural versatility. The second beam 2 can be designed differently to meet the attribute requirements of vehicle models of different weights. Attribute requirements are understood as the functional characteristics that the second beam 2 can achieve. For example, the second beam 2 can form a closed cavity, which can serve as an air spring reservoir, fulfilling the function of an air spring reservoir; or it can form a through cavity, which can serve as a gas pipe, enabling exhaust flow. The cross-section design of the second beam 2 to meet attribute requirements is described in detail below.

[0032] like Figures 1-7 As shown, the first beam 1 has a receiving cavity 12 with an opening 11, and the second beam 2 extends to the receiving cavity 12 through the opening 11. The first beam 1 and the second beam 2 are detachably connected, and the second beam 2 has a through cavity and / or a closed cavity.

[0033] The second beam body 2 comprises a support beam 21 abutting against the cavity wall of the accommodating cavity 12 and a fixing beam 22 extending outside the opening 11. The support beam 21 provides stable support for the cavity wall of the accommodating cavity 12, strengthens the connection strength of the first beam body 1 and the second beam body 2, and meets the energy-absorbing collision requirements of the rocker beam. The fixing beam 22 extends out of the opening 11, facilitating the embedded installation or disassembly and separation operation of the second beam body 2 and the accommodating cavity 12. At the same time, the opening 11 provides a larger installation space for the support beam 21, and the support beam 21 can be completely embedded in the accommodating cavity 12 or can exceed the volume of the accommodating cavity 12 from the position of the opening 11, providing a larger applicable range for the support beam 21 to meet the attribute requirements.

[0034] The accommodating cavity 12 has an opening 11 arranged downward along the longitudinal direction, and the fixing beam 22 supports the support beam 21 and is connected to the bottom of the first beam body 1. The fixing beam 22 is installed on the first beam body 1 in a downward manner, and the installation position of the fixing beam 22 does not affect the assembly of the main body of the first beam body 1 and other components on the vehicle, that is, the connection relationship between the first beam body 1 and the surrounding components remains unchanged. The first beam body 1 can be a universal structure, and the extrusion die for manufacturing the first beam body 1 can also be universal, greatly saving the cost of manufacturing the first beam body 1. The support beam 21 is embedded in the accommodating cavity 12, and the fixing beam 22 is located outside the opening 11. The fixing beam 22 is more easily operated and installed with the first beam body 1 outside the opening 11, avoiding the inconvenience caused by operating the support beam 21.

[0035] The second beam body 2 comprises a plurality of partition beams 23, and the partition beams 23 divide the through cavity and / or the closed cavity into a plurality of first sub-cavities 24. The plurality of first sub-cavities 24 can be selected according to the use requirements, and any single first sub-cavity 24 can be a through cavity or a closed cavity. The plurality of first sub-cavities 24 can meet various matching forms, further improving the application range of the rocker beam. The volume of the first sub-cavity 24 can be determined by the partition beam 23, and different cross-sectional designs of the second beam body 2 can meet the volume requirements of different first sub-cavities 24. The number, thickness and shape of the partition beam 23 can be adjusted to meet the collision attribute requirements.

[0036] In the embodiment, end covers 3 are arranged at both ends of the second beam body 2 along the length direction of the vehicle to close at least part of the end surface of the second beam body 2 to form a closed cavity, and an interface 31 for connecting an air spring controller is arranged on the end cover 3. The closed cavity serves as an air spring tank and communicates with the air spring controller, which is equivalent to integrating the air spring tank in the rocker beam. Therefore, it is not necessary to additionally arrange an air spring tank on the vehicle, which saves the space for arranging the air spring tank and reduces the weight of the vehicle.

[0037] The first beam body 1 in the embodiment is formed with a receiving cavity 12 with an opening 11, the second beam body 2 extends to the receiving cavity 12 through the opening 11, the first beam body 1 is detachably connected with the second beam body 2, the second beam body 2 is formed with a through cavity and / or a closed cavity, on the basis of not affecting the assembly relationship between the first beam body 1 and the vehicle, the second beam body 2 can adaptively adjust the cross-sectional design according to the attribute requirement, the assembly of the first beam body 1 and the second beam body 2 is flexible, so that the rocker beam can meet the general requirement and different attribute requirements, and performance redundancy is avoided; the general purpose of the rocker beam is improved, so as to increase the application range of the rocker beam.

According to the actual use requirement of the closed cavity, the end covers 3 can close the two ends of all the first sub-cavities 24, or can close the two ends of part of the first sub-cavities 24, and different use requirements can be met by replacing the second beam body 2.

[0045] In other embodiments, asFigure 5 As shown, a first support part 26 is a continuous structure and is provided in one section, and another first support part 26 is a non-continuous structure and can be provided in multiple sections; the two oppositely arranged first support parts 26 are still connected through the second support part 27 and the third support part 28, and a plurality of partition beams 23 are arranged between the two first support parts 26, and the partition beams 23 separate the support beam 21 into a plurality of first sub-cavities 24. Among them, part of the first sub-cavities 24 are formed between the first support part 26 with a continuous structure and the cavity wall of the accommodating cavity 12, and the attribute requirements of the first sub-cavities 24 can also be achieved, and the part of the structure of the first support part 26 is defaulted, and the space occupation is reduced, but when the first sub-cavity 24 is a closed cavity, the sealing performance of the cooperation between the first support part 26 and the accommodating cavity 12 still needs to be considered, for example, the first support part 26 with a non-continuous structure can be matched with the cavity wall of the accommodating cavity 12 through a sealing layer, which will not be described here. The first sub-cavity 24 can be arranged with a pipeline to achieve the attribute requirements of the pipeline transmission medium.
