Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a longitudinal beam structure for a vehicle and a vehicle having the same. Background Technology

[0002] With the rapid development of intelligent driving and new energy vehicle technologies, innovation in vehicle chassis and body structures has become a key direction for improving vehicle performance, giving rise to the concept of "corner modules." In related technologies, corner modules improve vehicle performance through steer-by-wire, in-wheel motors, and integrated subframes. However, due to the elimination of traditional subframes and the increased tire envelope, the longitudinal beams of traditional vehicles have a large span, making it difficult to meet the demands of large wheel rotation angles. Therefore, traditional longitudinal beam structures can no longer meet current usage requirements. Utility Model Content

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a longitudinal beam structure for a vehicle that avoids wheel envelopment, thereby providing greater rotational space for the vehicle's wheels to meet the requirements of large-angle wheel rotation.

[0004] This utility model further proposes a vehicle having the longitudinal beam structure described above.

[0005] The longitudinal beam structure of a vehicle according to an embodiment of the present invention includes: two longitudinal beam bodies, which are spaced apart along the width direction of the vehicle; each longitudinal beam body includes: a first longitudinal beam segment and a second longitudinal beam segment, the first longitudinal beam segment and the second longitudinal beam segment are connected, and along the length direction of the vehicle, the first longitudinal beam segment is located in front of the second longitudinal beam segment, extending from one end of the first longitudinal beam segment away from the second longitudinal beam segment to one end closer to the second longitudinal beam segment, with the two first longitudinal beam segments extending toward each other.

[0006] According to the vehicle longitudinal beam structure of this utility model embodiment, by extending the two first longitudinal beam segments in a direction of approach from the end of the first longitudinal beam segment away from the second longitudinal beam segment to the end of the first longitudinal beam segment close to the second longitudinal beam segment, the wheel envelope can be avoided, thereby providing a larger rotation space for the vehicle wheels to meet the requirements of large-angle wheel rotation.

[0007] According to some embodiments of this utility model, the distance between the two first longitudinal beam segments and the second longitudinal beam segment is D, which satisfies the relationship: 420mm≤D≤900mm.

[0008] According to some embodiments of this utility model, the distance between the two second longitudinal beam segments is E, which satisfies the relationship: 400mm≤E≤850mm.

[0009] According to some embodiments of this utility model, the included angle between the first longitudinal beam segment and the second longitudinal beam segment is α, which satisfies the relationship: 150°≤α<180°.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] The following is for reference. Figures 1-4 The present invention describes a longitudinal beam structure 3 of a vehicle according to an embodiment of the present invention, and a vehicle having therein.

[0029] like Figure 1 As shown, the longitudinal beam structure 3 of the vehicle according to an embodiment of the present utility model includes: two longitudinal beam bodies 31, which are spaced apart along the width direction of the vehicle; the longitudinal beam body 31 includes: a first longitudinal beam segment 311 and a second longitudinal beam segment 312, the first longitudinal beam segment 311 and the second longitudinal beam segment 312 are connected, and along the length direction of the vehicle, the first longitudinal beam segment 311 is located in front of the second longitudinal beam segment 312, and the two first longitudinal beam segments 311 extend from the end of the first longitudinal beam segment 311 away from the second longitudinal beam segment 312 to the end close to the second longitudinal beam segment 312, and the two first longitudinal beam segments 311 extend toward each other.

[0030] The longitudinal beam structure 3 of the vehicle can serve as the vehicle's skeleton. Along the width direction of the vehicle (Y-direction), two longitudinal beam bodies 31 are spaced apart. Each longitudinal beam body 31 includes a first longitudinal beam segment 311 and a second longitudinal beam segment 312, which are connected. In some embodiments of this application, the first and second longitudinal beam segments 311 and 312 can be integrally formed. Along the length direction of the vehicle (X-direction), the first longitudinal beam segment 311 is located in front of the second longitudinal beam segment 312. The end of the first longitudinal beam segment 311 away from the second longitudinal beam segment 312 can be connected (directly or indirectly) to the energy-absorbing box of the anti-collision beam assembly. The end of the second longitudinal beam segment 312 away from the first longitudinal beam segment 311 can be connected (directly or indirectly) to the vehicle's tower. As some embodiments of this application, such as... Figure 1 As shown, the energy-absorbing box may have a mounting plate 141, which may be screwed or welded to the energy-absorbing box. The end of the first longitudinal beam segment 311 away from the second longitudinal beam segment 312 may be screwed or welded to the mounting plate 141. As some embodiments of this application, the end of the second longitudinal beam segment 312 away from the first longitudinal beam segment 311 may be connected to the tower pack via a connecting bracket, that is, the end of the second longitudinal beam segment 312 away from the first longitudinal beam segment 311 may be connected to the connecting bracket (screwed or welded, etc.), and the connecting bracket may be connected to the tower pack (screwed or welded, etc.).

[0031] Along the length of the vehicle, from the end of the first longitudinal beam segment 311 furthest from the second longitudinal beam segment 312 to the end closest to the second longitudinal beam segment 312, the two first longitudinal beam segments 311 extend towards each other. In other words, from the rear to the front of the vehicle, the distance between the two first longitudinal beam segments 311 gradually increases, or the two first longitudinal beam segments 311 can form a figure-eight-like structure. This design provides diagonal support and facilitates the formation of a stable triangular-like structure between the longitudinal beam body 31 and other components, thereby improving the overall stability of the vehicle and enhancing its impact resistance.

[0032] When a vehicle is subjected to a frontal or oblique collision (e.g., an oblique collision could be a 40% offset collision), the impact energy can be sequentially transferred through the energy-absorbing box to the first longitudinal beam segment 311, the second longitudinal beam segment 312, and the tower. The energy-absorbing box, the first longitudinal beam segment 311, the second longitudinal beam segment 312, and the tower can form a stable transmission path, which can transfer the collision force to the components at the center of the vehicle, thereby effectively absorbing the collision energy, reducing the harm to the occupants of the vehicle's passenger compartment, and protecting the safety of the occupants.

[0033] It should be noted that existing and future intelligent vehicles increasingly need to meet the requirements of large-angle wheel rotation, and the tire envelope needs to occupy a relatively large space, which will encroach on the space in the width direction of the vehicle. Through the longitudinal beam structure 3 of this application embodiment, more rotation space can be provided for the wheel to meet the requirements of large-angle wheel rotation.

[0034] In the above embodiment, by extending the two first longitudinal beam segments 311 from the end of the first longitudinal beam segment 311 away from the end of the second longitudinal beam segment 312 to the end of the first longitudinal beam segment 312 in a direction of approach, the wheel envelope can be avoided, so as to provide a larger rotation space for the vehicle's wheels and meet the requirements of large-angle wheel rotation.

[0035] In some embodiments of this application, such as Figure 1 As shown, the distance between the two first longitudinal beam segments 311 and the second longitudinal beam segment 312 is D, which satisfies the relationship: 420mm≤D≤900mm.

[0036] In this design, both first longitudinal beam segments 311 extend along the length of the vehicle. The distance between the two first longitudinal beam segments 311 and the second longitudinal beam segment 312 can be D, which can satisfy the relationship: 420mm≤D≤900mm. D can be 420mm, 460mm, 600mm, 830mm, 900mm, etc. As some embodiments of this application, D can satisfy the relationship: 460mm≤D≤869mm. This arrangement allows for a smaller distance between the two first longitudinal beam segments 311 and the second longitudinal beam segment 312, providing more rotation space for the vehicle's wheels to meet the requirements for large-angle wheel rotation.

[0037] In some embodiments of this application, such as Figure 1 As shown, the distance between the two second longitudinal beam segments 312 is E, which satisfies the relationship: 400mm≤E≤850mm.

[0038] The distance between the two second longitudinal beam segments 312 can be E, in mm, and E satisfies the relationship: 400mm ≤ E ≤ 850mm. E can be 400mm, 460mm, 600mm, 830mm, or 850mm, etc. As some embodiments of this application, E can satisfy the relationship: 460mm ≤ E ≤ 830mm. This setting allows for flexible adjustment of the distance between the two second longitudinal beam segments 312 to adapt to the spatial layout of different vehicles, and also provides greater rotation space for the vehicle wheels to meet the requirements of large-angle wheel rotation.

[0039] In some embodiments of this application, such as Figure 1 As shown, the included angle between the first longitudinal beam segment 311 and the second longitudinal beam segment 312 is α, which satisfies the relationship: 150°≤α<180°.

[0040] Among them, the included angle between the first longitudinal beam segment 311 and the second longitudinal beam segment 312 can be α, and α can satisfy the relational expression: 150° ≤ α < 180°, and α can be 150°, 160°, 170°, 179°, etc. The included angle between the first longitudinal beam segment 311 and the second longitudinal beam segment 312 can be set to different values according to different vehicle models to adapt to the corresponding vehicle and different spatial layouts, and the performance of the diagonal support of the longitudinal beam body 31 can be reliable to meet the requirements of the offset collision of the vehicle.

[0041] In some embodiments of the present application, such as Figure 1 and Figure 2 As shown, the longitudinal beam structure 3 further includes: a partition plate 32. The longitudinal beam body 31 forms a cavity 313, and the partition plate 32 is arranged in the cavity 313 to divide the cavity 313 into multiple sub-cavities 3133.

[0042] Among them, the longitudinal beam structure 3 may further include a partition plate 32. The longitudinal beam body 31 forms a cavity 313, and the cavity 313 extends along the extension direction of the longitudinal beam body 31. The partition plate 32 can be arranged in the cavity 313. As some embodiments of the present application, the partition plate 32 can be integrally formed with the longitudinal beam body 31. The partition plate 32 can divide the cavity 313 into multiple sub-cavities 3133. When there is only one partition plate 32, the partition plate 32 can divide the cavity 313 into two sub-cavities 3133, so that the cross-section of the longitudinal beam body 31 is configured as a "day" - shaped structure. Such a setting can improve the collision protection ability of the longitudinal beam body 31. When a collision occurs, the longitudinal beam body 31 can effectively absorb the impact energy and effectively disperse the impact force generated by the impact to reduce the harm to the users in the occupant compartment of the vehicle and protect the safety of the users.

[0043] As some embodiments of the present application, there can be multiple partition plates 32, and multiple partition plates 32 are all arranged in the cavity 313. The multiple partition plates 32 can be integrally formed with the longitudinal beam body 31. The multiple partition plates 32 can divide the cavity 313 into multiple sub-cavities 3133. When there are two partition plates 32, the cross-section of the longitudinal beam body 31 can be configured as a "field" - shaped structure or an "eye" - shaped structure. When there are four partition plates 32, the cross-section of the longitudinal beam body 31 can be configured as a nine - grid structure. The number and arrangement form of the partition plates 32 can be set according to the actual cross - section force requirements and will not be elaborated here. By setting multiple partition plates 32, the collision protection ability of the longitudinal beam body 31 can be further improved.

[0044] In some embodiments of the present application, such as Figure 4 As shown, the longitudinal beam structure 3 of the vehicle further includes: a sleeve 34. The sleeve 34 is penetrated through the second longitudinal beam segment 312, and the sleeve 34 has an internal thread.

[0045] The sleeve 34 can be inserted into the second longitudinal beam section 312. The sleeve 34 can extend along the width direction of the vehicle. The sleeve 34 has internal threads. Bolts can be inserted into the sleeve 34 and the connecting bracket to connect the second longitudinal beam section 312 to the connecting bracket, so that the second longitudinal beam section 312 is connected to the tower. This configuration is simple, easy to assemble, has a stable connection, and is easy to implement.

[0046] As some embodiments of this application, there may be multiple sleeves 34, and multiple sleeves 34 can be used to connect the second longitudinal beam segment 312 and the connecting bracket. Setting multiple sleeves 34 can further improve the connection strength.

[0047] In some embodiments of this application, such as Figure 1 As shown, the second longitudinal beam segment 312 extends along the length of the vehicle and is adapted to connect with the vehicle's tower.

[0048] The second longitudinal beam segment 312 can run along the length of the vehicle. The end of the second longitudinal beam segment 312 away from the first longitudinal beam segment 311 can be connected to the vehicle's tower gear via a connecting bracket. In other words, the connecting bracket can connect the second longitudinal beam segment 312 and the tower gear. The connecting bracket can have multiple mounting points; some of these points can be used to mount the second longitudinal beam segment 312, while others can be used to mount the tower gear. This arrangement allows the force on the second longitudinal beam segment 312 to be smoothly and accurately transferred to the tower gear through the connecting bracket, forming a stable and reliable force transmission channel. Furthermore, since the tower gear and the second longitudinal beam segment 312 are generally made of different materials, the connecting bracket facilitates the connection between the second longitudinal beam segment 312 and the tower gear.

[0049] As some embodiments of this application, the material of the longitudinal beam body 31 may be, but is not limited to, aluminum, and the longitudinal beam body 31 may be extruded and bent into shape.

[0050] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, the end face of the second longitudinal beam segment 312, which is away from the first longitudinal beam segment 311, extends obliquely along the length of the vehicle.

[0051] Along the length of the vehicle, the end face of the second longitudinal beam segment 312 away from the first longitudinal beam segment 311 can extend obliquely. That is, the end face of the second longitudinal beam segment 312 away from the first longitudinal beam segment 311 is an inclined plane, and the normal to this inclined plane is perpendicular to the vehicle's X and Z directions (e.g., ...). Figure 3As shown, the second longitudinal beam segment 312 is not parallel to the first longitudinal beam segment 311. In some embodiments of this application, along the height direction of the vehicle and from top to bottom, the end face of the second longitudinal beam segment 312 away from the first longitudinal beam segment 311 gradually moves away from the first longitudinal beam segment 311. By making the end face of the second longitudinal beam segment 312 away from the first longitudinal beam segment 311 extend obliquely along the length direction of the vehicle, this arrangement can reduce the idle travel during the collision process, disperse the impact energy, avoid stress concentration, reduce the peak load of the tower pack, and improve collision performance.

[0052] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, the longitudinal beam structure 3 of the vehicle also includes a mounting bracket 33, which is disposed on the longitudinal beam body 31. The mounting bracket 33 has a mounting part 331, which is adapted to be connected to the vehicle's components; and / or, the longitudinal beam body 31 also includes a transition section 314, which is connected between the first longitudinal beam section 311 and the second longitudinal beam section 312, and the transition section 314 is constructed as an arc-shaped section.

[0053] The mounting bracket 33 can be located on the longitudinal beam body 31. The mounting bracket 33 can have a mounting part 331, which can be constructed as a hole. The mounting part 331 is used to install corresponding vehicle parts, such as water tanks, radiator water pipes, wiring, etc. This structure is reasonable and can provide mounting points for vehicle parts through the longitudinal beam body 31, reducing design difficulty. It can also make full use of the interior space and improve the installation stability of the parts.

[0054] The transition section 314 can be connected between the first longitudinal beam section 311 and the second longitudinal beam section 312. The transition section 314 is constructed as an arc-shaped section to adapt to the first longitudinal beam section 311 and the second longitudinal beam section 312 with different extension directions, so as to make the connection between the first longitudinal beam section 311 and the second longitudinal beam section 312 smooth, avoid stress concentration, and further improve collision resistance.

[0055] The vehicle according to the embodiments of this application includes the longitudinal beam structure 3 of the vehicle described in the above embodiments. By extending the two first longitudinal beam segments 311 from one end away from the second longitudinal beam segment 312 to the end near the second longitudinal beam segment 312, the two first longitudinal beam segments 311 extend toward each other, thus avoiding wheel envelopment and providing greater rotation space for the vehicle's wheels to meet the requirements for large-angle wheel rotation.
