[0024] It should be noted that the directions involved in this article, such as the left-right direction, are the width directions of the vehicle, the front-back direction, are the length directions of the vehicle, and the height direction, are the height directions of the vehicle.

[0025] The present application proposes a vehicle.

[0026] The vehicle may be a sedan, an off-road vehicle, etc., and the vehicle may also include a fuel vehicle, an electric vehicle, or an extended-range vehicle, etc., which are not limited here.

[0027] Specifically, the vehicle includes a left longitudinal beam, a right longitudinal beam and a leg cross beam assembly 10. The leg cross beam assembly 10 is used to install the leveling legs, and the leg cross beam assembly 10 is used to connect the left longitudinal beam and the right longitudinal beam to improve the strength and rigidity of the frame, and can balance the torque applied to the frame by the ground through the leveling legs, so that the overall force of the frame is balanced.

[0028] Please refer to Figure 1 The leg crossbeam assembly 10 includes: two leg crossbeams 1 and a supporting crossbeam 2.

[0029] The two sides of the supporting crossbeam 2 are respectively fixedly connected to the inner side surfaces of the left longitudinal beam and the right longitudinal beam of the frame, one leg crossbeam 1 is fixedly arranged on the side of the left longitudinal beam of the frame away from the supporting crossbeam 2, and the other leg crossbeam 1 is fixedly arranged on the side of the right longitudinal beam of the frame away from the supporting crossbeam 2, wherein the supporting crossbeam 2, the leg crossbeam 1 and the frame can adopt an integrated design, that is, the supporting crossbeam 2, the leg crossbeam 1 and the frame are constructed as an integrated structure to improve the strength and rigidity of the frame.

[0030] Among them, the supporting beam 2 includes a beam body 21 and a mounting bracket 22. The beam body 21 can be used to connect the left longitudinal beam and the right longitudinal beam of the frame, and the beam body 21 is connected between the two leg beams 1. The connection method between the beam body 21 and the leg beam 1 can be bolt connection, clamping, welding, etc., which is not limited here.

[0031] Furthermore, the mounting bracket 22 is connected to the cross beam body 21, and the mounting bracket 22 is used to install the battery pack. In this way, the assembly of the battery pack will not affect the assembly of the cross beam body 21 and other structures, and the battery pack can be assembled on the mounting bracket 22, so that the leg cross beam assembly 10 has the function of installing the battery pack, and further the leg cross beam assembly 10 can meet the use requirements, so that the layout of the whole vehicle can be made more compact.

[0032] Among them, the mounting bracket 22 may be provided with a first mounting interface 221 for fixedly connecting with the battery pack, so that the battery pack can be screwed to the mounting bracket 22 through the first mounting interface 221, or the mounting bracket 22 may be provided with a welding surface for welding the battery pack, so that the battery pack can be welded to the mounting bracket 22. In other words, the mounting bracket 22 is used to provide a mounting position for the installation of the battery pack. The connection method between the mounting bracket 22 and the battery pack can be the above-mentioned screw connection, or welding, etc. Of course, the connection method between the mounting bracket 22 and the battery pack can also be other methods, as long as the battery pack can be fixed, and there is no limitation here.

[0033] In some implementations, the mounting bracket 22 may be welded to the beam body 21 to enhance the connection strength between the mounting bracket 22 and the beam body 21 , or the mounting bracket 22 may be screwed to the beam body 21 to facilitate disassembly and maintenance of the mounting bracket 22 .

[0034] In some implementations, in the front-rear direction of the vehicle, the mounting bracket 22 is located at the front side or the rear side of the cross beam body 21 , so that the setting of the mounting bracket 22 will not interfere with the left longitudinal beam or the right longitudinal beam, which helps to reduce the difficulty of setting the mounting bracket 22 .

[0035] In some implementations, the mounting bracket 22 is located between the two leg cross beams 1 , so that the installation of the mounting bracket 22 will not interfere with the leg cross beams 1 , which helps to reduce the difficulty of setting the mounting bracket 22 .

[0036] According to the outrigger cross beam assembly 10 of the embodiment of the present application, its supporting cross beam 2 includes a mounting bracket 22, and the battery pack can be assembled on the mounting bracket 22, so that the outrigger cross beam assembly 10 has the function of installing the battery pack, and further enables the outrigger cross beam assembly 10 to meet the use requirements, thus making the layout of the entire vehicle more compact.

[0037] In some embodiments, Figure 1 As shown, the supporting cross beam 2 and the leg cross beams 1 are staggered so that an installation space 23 is defined between the supporting cross beam 2 and the two leg cross beams 1 , and the installation bracket 22 is located in the installation space 23 .

[0038] Therefore, the supporting crossbeam 2 and the leg crossbeam 1 can be staggered to define an installation space 23 between the supporting crossbeam 2 and the two leg crossbeams 1, and the installation bracket 22 is located in the installation space 23, which can reduce the difficulty of arranging the installation bracket 22 and make the arrangement of the installation bracket 22 and the crossbeam body 21 more compact.

[0039] In particular, after the battery pack is installed in the installation space 23, at least part of the battery pack can be located in the installation space 23. In this way, the support beam 2 and the leg beam 1 can be staggered to provide layout space for the installation of the battery pack, further reducing the difficulty of arranging the battery pack. The support beam 2 and the leg beam 1 can also play a certain limiting role on the battery pack to further enhance the stability of the battery pack.

[0040] In some embodiments, Figure 1 As shown, the leg beam assembly 10 also includes a transition bracket 5, which is connected between the beam body 21 and the mounting bracket 22, so that the mounting bracket 22 can be connected to the beam body 21 through the transition bracket 5, and the mounting bracket 22 can be detachably connected to the transition bracket 5, for example, the mounting bracket 22 can be screwed to the transition bracket 5, so that it is convenient to disassemble the battery pack to realize the inspection and replacement of the battery pack, etc. Of course, the connection method between the mounting bracket 22 and the transition bracket 5 can also be other methods, which are not limited here.

[0041] In some embodiments, Figure 1 As shown, the mounting bracket 22 is provided with a first mounting interface 221 for connecting to the battery pack.

[0042] Thus, the battery pack can be installed on the mounting bracket 22 through the first mounting interface 221, that is, a mounting position is provided for the battery pack through the mounting bracket 22, which is beneficial to the arrangement of the battery pack and enables the mounting bracket 22 to have the function of installing the battery pack, thereby improving the functionality of the leg cross beam assembly 10, and integrating the battery pack into the mounting bracket 22 can make the layout of the entire vehicle more compact.

[0043] In some embodiments, Figure 1 As shown, the cross beam body 21 is provided with a second mounting interface 24 for connecting with a cabin of a vehicle.

[0044] Thus, the cabin of the vehicle can be installed on the crossbeam body 21 through the second mounting interface 24, that is, a mounting position is provided for the cabin of the vehicle through the crossbeam body 21, which is beneficial to the arrangement of the cabin of the vehicle, so that the crossbeam body 21 has the function of installing the cabin of the vehicle, thereby improving the functionality of the support leg crossbeam assembly 10.

[0045] In some embodiments, Figure 1As shown, the leg cross beam assembly 10 further includes: a structural reinforcement 3 , which is connected between the supporting cross beam 2 and at least one leg cross beam 1 .

[0046] For example, see Figure 1 A structural reinforcement 3 is provided between the support beam 2 and each leg beam 1, and the structural reinforcement 3 is arranged across the connection between the support beam 2 and the corresponding leg beam 1. Therefore, by providing the structural reinforcement 3, the connection strength between the support beam 2 and the leg beam 1 is enhanced, and the overall strength and rigidity of the leg beam assembly 10 can be increased to meet the design requirements of the load-bearing capacity of the leg beam assembly 10.

[0047] For example, the structural reinforcement 3 may be a reinforcement rib or a box-shaped structure. Preferably, the structural reinforcement 3 in the embodiment of the present application is a box-shaped structure. The box-shaped structure is convenient for enhancing the connection strength between the supporting beam 2 and the leg beam 1, and an energy-absorbing cavity may be formed in the box-shaped structure to absorb part of the impact, thereby better enhancing the connection strength between the supporting beam 2 and the leg beam 1.

[0048] In some embodiments, Figure 1 As shown, the structural reinforcement member 3 is provided with a weight-reducing hole 4 , so that it is convenient to reduce the weight of the structural reinforcement member 3 to achieve a lightweight design of the structural reinforcement member 3 .

[0049] In some embodiments, Figure 1 As shown, in the direction from the supporting cross beam 2 to the leg cross beam 1, the cross-sectional area of ​​the leg cross beam 1 presents a decreasing trend.

[0050] For example, in the direction from the support beam 2 to the leg beam 1, the upper side of the leg beam 1 extends in the left-right direction, while the lower side of the leg beam 1 extends upwardly at an angle, so that the cross-sectional area of ​​the leg beam 1 shows a downward trend. Alternatively, in the direction from the support beam 2 to the leg beam 1, the lower side of the leg beam 1 extends in the left-right direction, while the upper side of the leg beam 1 extends downwardly at an angle, so that the cross-sectional area of ​​the leg beam 1 shows a downward trend. Thus, the structural strength of the leg beam 1 is improved.

[0051] Preferably, in the embodiment of the present application, in the direction from the supporting beam 2 to the leg beam 1, the upper side surface of the leg beam 1 extends in the left-right direction, while the lower side surface of the leg beam 1 extends upwardly inclined, so that the cross-sectional area of ​​the leg beam 1 shows a downward trend. In this way, when the leveling leg is installed at the end of the leg beam 1 away from the supporting beam 2, the ground clearance of the leveling leg can meet the design requirements.

[0052] In some embodiments, Figure 1 and Figure 2As shown, a third mounting interface 11 for mounting a leveling leg is provided at one end of the leg beam 1 away from the supporting beam 2 .

[0053] Thus, the leveling leg can be installed on the leg beam 1 through the third mounting interface 11, that is, the leg beam 1 provides a mounting position for the leveling leg, which is beneficial to the arrangement of the leveling leg, so that the leg beam 1 has the function of installing the leveling leg, thereby improving the functionality of the leg beam assembly 10, and integrating the leveling leg into the leg beam 1 can make the layout of the entire vehicle more compact.

[0054] Among them, the third installation interface 11 is arranged at one end of the leg beam 1 away from the supporting beam 2 to avoid interference between the leveling leg and the supporting beam 2, which is conducive to reducing the difficulty of setting the leveling leg.

[0055] It should be noted that, in the direction from the supporting beam 2 to the leg beam 1, the cross-sectional area of ​​the leg beam 1 shows a downward trend, so that the end of the leg beam 1 away from the supporting beam 2 is concave relative to the end of the leg beam 1 connected to the supporting beam 2. In this way, when the leveling leg is installed on the end of the leg beam 1 away from the supporting beam 2, the ground clearance of the leveling leg can meet the design requirements.

[0056] In some embodiments, Figure 1 and Figure 2 As shown, the leg cross beam 1 is provided with a fourth mounting interface 12 for mounting a radiator.

[0057] Thus, the radiator can be installed on the leg cross beam 1 through the fourth mounting interface 12, that is, the leg cross beam 1 provides a mounting position for the radiator, which is beneficial to the arrangement of the radiator and makes the leg cross beam 1 have the function of installing the radiator, thereby improving the functionality of the leg cross beam assembly 10, and integrating the radiator into the leg cross beam 1 can make the layout of the entire vehicle more compact.

[0058] In some embodiments, the fourth mounting interface 12 is disposed on a side of the leg cross beam 1 facing the cabin of the vehicle, so that the setting position of the fourth mounting interface 12 meets the arrangement requirements of the radiator.

[0059] In some embodiments, Figure 1 and Figure 2 As shown, the third mounting interface 11 and the fourth mounting interface 12 are located on different sides of the leg cross beam 1 , so that the leveling leg and the radiator can be installed on different sides of the leg cross beam 1 to avoid interference between the leveling leg and the radiator.

[0060] In some embodiments, the leg cross beam 1 is provided with a through hole 13 for passing the steering tie rod.

[0061] As a result, it is convenient to provide assembly space and movement space for the steering rod through the support leg cross beam 1, which is beneficial to the arrangement of the steering rod, simplifies the layout structure of the steering system, and enables the support leg cross beam 1 to have the function of installing the steering rod, thereby improving the functionality of the support leg cross beam assembly 10, and integrating the steering rod into the support leg cross beam 1 can make the layout of the entire vehicle more compact.

[0062] In some embodiments, Figure 1 and Figure 2 As shown, the through hole 13 is penetrated in the front-to-back direction, so that the steering rod can be arranged in the support leg cross beam 1 in the front-to-back direction, and the steering rod can be prevented from interfering with structures such as the radiator or the leveling support leg.

[0063] In some embodiments, Figure 1 As shown, the supporting beam 2 is constructed as a box-shaped structure, thereby making the supporting beam 2 a hollow structure, which is convenient for reducing the weight of the supporting beam 2 to achieve a lightweight design of the supporting beam 2.

[0064] In some embodiments, Figure 1 and Figure 2 As shown, the leg cross beam 1 is constructed as a box-shaped structure, thereby making the leg cross beam 1 a hollow structure, which is convenient for reducing the weight of the leg cross beam 1 to achieve a lightweight design of the leg cross beam 1.

[0065] In some embodiments, Figure 1 As shown, the supporting cross beam 2 and / or the leg cross beam 1 are provided with lightening holes 4 .

[0066] For example Figure 1 As shown, the supporting crossbeam 2 is provided with a weight-reducing hole 4 , which makes it easy to reduce the weight of the supporting crossbeam 2 , so as to achieve a lightweight design of the supporting crossbeam 2 .

[0067] Or Figure 1 and Figure 2 As shown, the leg cross beam 1 is provided with a weight-reducing hole 4 , which makes it easy to reduce the weight of the supporting cross beam 2 , so as to achieve a lightweight design of the supporting cross beam 2 .

[0068] Or Figure 1 As shown, both the supporting crossbeam 2 and the leg crossbeam 1 are provided with weight-reducing holes 4 , so as to facilitate reducing the weight of the supporting crossbeam 2 and the leg crossbeam 1 , so as to achieve a lightweight design of the leg crossbeam assembly 10 .
