Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to an integrated beam structure and vehicle. Background Technology

[0002] With the rapid increase in social productivity, the logistics and transportation industry has developed rapidly, and the surge in commercial vehicle ownership has put considerable pressure on road resources and environmental protection. At the same time, vehicle overloading can easily lead to safety accidents and excessive emissions. Therefore, vehicle lightweighting is an important measure to improve transportation efficiency and reduce vehicle fuel consumption and emissions.

[0003] The chassis of a heavy commercial vehicle includes two longitudinal beams, cross beams, thrust supports, and towing seat connecting plates. In the existing technology, each component of the chassis adopts a split design, which requires assembly one by one during the vehicle assembly process. This not only results in low work efficiency but also leads to a large chassis weight, which cannot meet the requirements for lightweighting. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated crossbeam structure and vehicle that can reduce the weight of the chassis and achieve lightweighting.

[0005] To achieve the above objectives, the following technical solution is provided:

[0006] On the one hand, an integrated beam structure is provided, including:

[0007] Two longitudinal beam connecting plates are respectively used to fix and connect to the two longitudinal beams of the vehicle frame;

[0008] A crossbeam, the two ends of which are respectively fixedly connected to the two longitudinal beam connecting plates;

[0009] Two thrust supports are respectively disposed on both sides of the crossbeam; the two thrust supports are respectively used to connect to two thrust rods;

[0010] Two traction seat connectors are provided, and the two traction seat connectors and the crossbeam are arranged sequentially along the extension direction of the longitudinal beam; each traction seat connector includes a connecting plate, the top surface of the connecting plate is higher than the top surface of the longitudinal beam, and both ends of the connecting plate are provided with support parts, one end of the support part is connected to the bottom of the connecting plate, and the other end is fixedly connected to the longitudinal beam connecting plate.

[0011] As an alternative to the integrated beam structure, the length of the connecting plate is greater than the distance between the two longitudinal beam connecting plates.

[0012] As an optional solution for the integrated beam structure, the connecting plate has flanges on both sides in the width direction.

[0013] As an optional solution for the integrated beam structure, the height difference between the top surface of the beam and the top surface of the longitudinal beam is H, and H gradually decreases along the length direction of the beam from the middle to the end of the beam.

[0014] As an alternative to the integrated beam structure, the beam includes:

[0015] The main body has a T-shaped cross-section; the cross-section is parallel to the longitudinal beam connecting plate.

[0016] Two connecting seats are provided, and the two ends of the main body are respectively connected to the two longitudinal beam connecting plates through the two connecting seats. The connecting seats are hollow structures.

[0017] As an optional solution for the integrated beam structure, one end of the connecting seat connected to the longitudinal beam connecting plate is an open structure, and the longitudinal beam connecting plate is provided with through holes corresponding to the open structure.

[0018] As an alternative to the integrated beam structure, the main body includes a vertical plate and a top plate, with the top plate fixed to the top of the vertical plate to form the T-shaped structure;

[0026] The integrated beam structure and vehicle of the present invention integrate the beam, thrust support and traction seat connector into one unit. Compared with the prior art, it not only reduces the number of frame parts and achieves weight reduction, but also improves assembly efficiency and enhances the bending and torsional resistance of the frame.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] like Figure 1-3 As shown, this embodiment provides an integrated crossbeam structure, including a crossbeam 1, two thrust supports 2, two traction seat connectors 3, and two longitudinal beam connecting plates 4. The two longitudinal beam connecting plates 4 are respectively used to fixally connect to two longitudinal beams of the frame, namely the left longitudinal beam 110 and the right longitudinal beam 120. The two ends of the crossbeam 1 are respectively fixedly connected to the two longitudinal beam connecting plates 4. The two thrust supports 2 are respectively provided on both sides of the crossbeam 1. The two thrust supports 2 are respectively used to connect to two thrust rods. The two traction seat connectors 3 and the crossbeam 1 are arranged sequentially along the extension direction of the longitudinal beam. The traction seat connector 3 includes a connecting plate 31, the top surface of the connecting plate 31 is higher than the top surface of the longitudinal beam, and both ends of the connecting plate 31 are provided with support parts 32. One end of the support part 32 is connected to the bottom of the connecting plate 31, and the other end is fixedly connected to the longitudinal beam connecting plate 4.

[0044] The integrated crossbeam structure of this embodiment integrates the crossbeam 1, the thrust support 2, and the traction seat connector 3 into one unit. Compared with the prior art, this not only reduces the number of frame parts and achieves weight reduction, but also improves assembly efficiency and enhances the bending and torsional resistance of the frame. At the same time, the top surface of the connecting plate 31 is higher than the top surface of the longitudinal beam, so that the traction seat 200 can be directly installed on the connecting plate 31. Compared with the existing traction seat 200 installation method, there is no need to set up other adapters such as the traction seat 200 base plate, further reducing the number of frame parts and lowering the frame weight to achieve weight reduction.

[0045] Optionally, the length of the connecting plate 31 is greater than the distance between the two longitudinal beam connecting plates 4, so that the connecting plate 31 matches the structure of the traction seat 200, ensuring the installation stability of the traction seat 200, without the need to add other adapters.

[0046] Optionally, flanges 311 are provided on both sides of the connecting plate 31 in the width direction. The flanges 311 increase the strength of the connecting plate 31, which is conducive to further achieving lightweighting.

[0047] In this embodiment, the support part 32 is a plate-shaped structure, and the support part 32 and the flange 311 are integrally formed, which not only has high structural strength, but also good processability.

[0048] Optionally, the height difference H between the top surface of the crossbeam 1 and the top surface of the longitudinal beam gradually decreases along the length of the crossbeam 1 from the middle to the end. This arrangement allows the crossbeam 1 to avoid obstructing the frame or other structures mounted on the frame, and also improves its bending and torsional resistance.

[0049] Optionally, the crossbeam 1 includes a main body 11 and two connecting seats 12. The cross-section of the main body 11 is T-shaped and parallel to the longitudinal beam connecting plate 4. Both ends of the main body 11 are connected to the two longitudinal beam connecting plates 4 via the two connecting seats 12, which are hollow structures. This configuration, while ensuring the structural strength of the crossbeam 1, can reduce its weight, further achieving lightweighting.

[0050] Optionally, the end of the connecting seat 12 connected to the longitudinal beam connecting plate 4 is an open structure, and the longitudinal beam connecting plate 4 is provided with a through hole 41 corresponding to the open structure. By providing the through hole 41, the weight of the longitudinal beam connecting plate 4 can be reduced, thus achieving lightweighting.

[0051] Optionally, the main body 11 includes a vertical plate 111 and a top plate 112, with the top plate 112 fixed to the top of the vertical plate 111 to form a T-shaped structure. The main body 11 also includes a reinforcing connector 113, one end of which is connected to the bottom of the top plate 112, and the other end is connected to the vertical plate 111. By increasing the structural strength of the main body 11 through the reinforcing connector 113, the weight of the main body 11 is not excessively increased, thus meeting the requirements for lightweight design.

[0052] Optionally, the crossbeam 1 also includes a support plate 13, which is supported on the bottom of the connecting seat 12. Both ends of the support plate 13 are fixedly connected to the upright plate 111 and the longitudinal beam connecting plate 4, respectively, thereby ensuring that the crossbeam 1 has greater structural strength. In this embodiment, the support plate 13 and the upright plate 111 are integrally formed, resulting in higher structural strength and facilitating lightweighting.

[0053] In this embodiment, the thrust rod is an X-shaped thrust rod 300. Optionally, the thrust support 2 includes two support bodies 21, which are respectively fixed to two connecting seats 12. This arrangement facilitates connection between the two support bodies 21 and the X-shaped thrust rod 300. Integrating the support bodies 21 into the connecting seats 12 allows the connecting seats 12 to provide support and fixation for the support bodies 21, resulting in better stability. Furthermore, compared to existing technologies, there is no need for a separate thrust rod support, which is beneficial for achieving weight reduction.

[0054] Optionally, the crossbeam 1 is provided with a first weight-reduction structure 14; the traction seat connector 3 is provided with a second weight-reduction structure 33; and the longitudinal beam connecting plate 4 is provided with a third weight-reduction structure 42. This arrangement aims to further reduce the self-weight of the integrated crossbeam structure and meet the requirements for lightweight design.

[0055] Optionally, the first weight-reducing structure 14, the second weight-reducing structure 33, and the third weight-reducing structure 42 all employ weight-reducing holes or grooves. Of course, the shape of the weight-reducing holes or grooves can be selected according to requirements, such as circular, rectangular, or triangular shapes, and is not limited here.

[0056] For example, the first weight-reducing structure 14 is a weight-reducing hole formed in the upright plate 111 and the support plate 13. The second weight-reducing structure 33 is a weight-reducing hole formed in the connecting plate 31 and the support portion 32. The third weight-reducing structure 42 is a weight-reducing groove formed in the longitudinal beam connecting plate 4.

[0057] The integrated beam structure in this embodiment solves the problem of increased vehicle weight caused by separate component installation in the prior art, and achieves lightweighting from a structural perspective.

[0058] This embodiment also provides a vehicle, including the integrated crossbeam structure as described above and two longitudinal beams, with connecting plates 4 fixedly connected to the two longitudinal beams respectively. The vehicle of this embodiment, by applying the aforementioned integrated crossbeam structure, has the same beneficial effects as the integrated crossbeam structure described above, and will not be repeated here.

[0059] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
