[0033] See also Figure 1 The embodiment of the present application provides a vehicle frame 10 , including a first longitudinal beam 20 and a second longitudinal beam 21 arranged parallel to each other and a plurality of cross beams 30 .

[0034] A battery pack installation area 22 is provided between the first longitudinal beam 20 and the second longitudinal beam 21. Both ends of a plurality of cross beams 30 are fixedly connected to the first longitudinal beam 20 and the second longitudinal beam 21. The cross beams 30 include a first cross beam 31 and a second cross beam 32. The height of the second cross beam 32 from the ground is greater than the height of the first cross beam 31 from the ground. At least one second cross beam 32 is provided in the battery pack installation area 22.

[0035] The frame 10, battery frame structure 100 and vehicle provided in the embodiment of the present application divide the battery pack installation area 22 between the first longitudinal beam 20 and the second longitudinal beam 21, and provide at least one second cross beam 32 in the battery pack installation area 22 to free up part of the space between the first longitudinal beam 20 and the second longitudinal beam 21 to accommodate at least part of the battery pack 50, thereby increasing the height of the battery pack 50 from the ground.

[0036] The existing frame 10 design requires that storage space be set on both sides of the frame 10 to maximize the functional space utilization, so the battery pack 50 needs to be set between the first longitudinal beam 20 and the second longitudinal beam 21. The battery pack installation area 22 is marked between the first longitudinal beam 20 and the second longitudinal beam 21, and the battery pack 50 is placed in the battery pack installation area 22 during the subsequent assembly process.

[0037] The battery pack installation area 22 needs to install the battery pack, and the height of the battery pack 50 from the ground needs to be as large as possible to ensure the safety and stability of the battery pack 50. Therefore, a second crossbeam 32 different from the first crossbeam 31 used in the existing frame 10 needs to be set in the battery pack installation area 22. The height of the first crossbeam 31 from the ground is very small. Generally, the first crossbeam 31 is flush with the first longitudinal beam 20 and the second longitudinal beam 21, and a C-shaped connector is provided at the connection between the first crossbeam 31 and the first longitudinal beam 20 and the second longitudinal beam 21 to further strengthen the first crossbeam 31 and improve the stability and torsional resistance of the first crossbeam 31, while also limiting the height of the battery pack 50 from the ground when it is installed between the first longitudinal beam 20 and the second longitudinal beam 21.

[0038] The first cross beam 31 is arranged in the non-battery pack installation area between the first longitudinal beam 20 and the second longitudinal beam 21, and the second cross beam 32 which is arranged further away from the bottom surface after being lifted is arranged in the battery pack installation area 22. The height of the second cross beam 32 from the ground is greater than the height of the first cross beam 31 from the ground. By setting the second cross beam 32 in the battery pack installation area 22, part of the space between the first longitudinal beam 20 and the second longitudinal beam 21 is made available in the battery pack installation area 22 to accommodate at least part of the battery pack 50.

[0039] The specific size of the battery pack installation area 22 can be set according to the specific size of the battery pack 50. At the same time, the number and specific spacing of the second cross beams 32 of the battery pack installation area 22 can also be set according to the specific size of the battery pack 50 and the strength requirements of the frame 10. The size of the partial space between the first longitudinal beam 20 and the second longitudinal beam 21 by setting the second cross beam 32 can also be set according to the specific size of the battery pack 50. Optionally, one embodiment can be set so that the battery packs 50 are concentrated in one battery pack installation area 22, and the second cross beams 32 are evenly arranged in the battery pack installation area 22. The partial space between the first longitudinal beam 20 and the second longitudinal beam 21 provided by the second cross beam 32 accommodates all the battery packs 50. Another embodiment may also be arranged to split the battery pack 50 and arrange it in multiple battery pack installation areas 22, the second cross beam 32 is arranged in the multiple battery pack installation areas 22, and the battery packs 50 are respectively accommodated in multiple partial spaces vacated between the first longitudinal beam 20 and the second longitudinal beam 21 by setting the second cross beam 32. The embodiment of the present application is not limited to this, as long as the size of the battery pack installation area 22, the setting of the second cross beam 32, and the size of the partial space between the first longitudinal beam 20 and the second longitudinal beam 21 vacated by the setting of the second cross beam 32 can accommodate the specific size of the battery pack 50, so that the battery pack 50 can be lifted to a predetermined height from the ground.

[0040] See also Figure 1 and Figure 3 In some embodiments, the second cross beam 32 includes a combination tube 321 and two combination brackets 322. The combination tube 321 is fixedly connected to the first longitudinal beam 20 and the second longitudinal beam 21 through the combination bracket 322. The height of the combination tube 321 from the ground is greater than the height of the first cross beam 31 from the ground. At least one combination tube 321 is arranged in the battery pack installation area 22.

[0041] In these embodiments, the vehicle frame 10 provided in the embodiments of the present application is provided with a second cross beam 32 including a combined tube 321 and a combined bracket 322. The combined tube 321 can be partially lifted upward compared to the first cross beam 31, so that the height of the combined tube 321 from the ground is greater than the height of the first cross beam 31 from the ground. At the same time, the combined tube 321 is a hollow structure, so as to reduce the weight of the vehicle frame 10 while leaving part of the space between the first longitudinal beam 20 and the second longitudinal beam 21.

[0042] Compared with the first cross beam 31, the combined pipe 321 can be lifted upward by at least 73 mm, and sufficient safety clearance can be reserved. The second cross beam 32 adopts the arrangement mode of the combined pipe 321 and the combined bracket 322. Compared with the first cross beam 31, the combined pipe 321 is a hollow structure, which is lighter in weight. While leaving some space between the first longitudinal beam 20 and the second longitudinal beam 21, the weight of the frame 10 can be reduced.

[0043] See also Figure 1 and Figure 3 In some embodiments, the diameter of the combined tube 321 is smaller than the width of the first beam 31 .

[0044] In these embodiments, the frame 10 provided in the embodiments of the present application sets the diameter of the combined tube 321 to be smaller than the width of the first cross beam 31, thereby making the height of the combined tube 321 above the ground smaller than the height of the first cross beam 31, and thus the height of the second cross beam 32 above the ground smaller than the height of the first cross beam 31.

[0045] The height of the combined tube 321 from the ground can be affected by a variety of different ways of arranging the combined tube 321 and the combined bracket 322 in the second cross beam 32, wherein the height of the combined tube 321 from the ground can be affected by setting the diameter of the combined tube 321. The diameter of the combined tube 321 is set smaller than the width of the first cross beam 31, that is, the height of the combined tube 321 from the ground is smaller than the height of the first cross beam 31, that is, part of the space is left between the first longitudinal beam 20 and the second longitudinal beam 21, which can accommodate at least part of the battery pack.

[0046] Please continue reading Figure 3 In some embodiments, the combined bracket 322 includes a bracket body 3221 and two connecting plates 3222 , and the two connecting plates 3222 are vertically arranged on both sides of the bracket body 3221 on a side of the bracket body 3221 away from the combined tube 321 ;

[0047] The bracket body 3221 includes a first positioning hole 3223 that penetrates the bracket body 3221 , and the combined tube 321 is fixedly connected to the bracket body 3221 through the first positioning hole 3223 ;

[0048] The connecting plate 3222 includes a plurality of second positioning holes 3224 that penetrate the connecting plate 3222 . The connecting plate 3222 is fixedly connected to the first longitudinal beam 20 and the second longitudinal beam 21 through the second positioning holes 3224 .

[0049] In these embodiments, in the vehicle frame 10 provided in the embodiments of the present application, the combined tube 321 is fixedly connected to the bracket body 3221 via the first positioning hole 3223, and the connecting plate 3222 is fixedly connected to the first longitudinal beam 20 and the second longitudinal beam 21 via the second positioning hole 3224. The combined tube 321 can be partially raised in height by the provision of the first positioning hole 3223, thereby leaving some space between the first longitudinal beam 20 and the second longitudinal beam 21 to accommodate at least part of the battery pack 50, thereby raising the height of the battery pack 50 from the ground.

[0050] Please continue reading Figure 1 and Figure 3 In some embodiments, the height of the first positioning hole 3223 from the ground is greater than the height of the first beam 31 from the ground.

[0051] In these embodiments, the frame 10 provided in the embodiments of the present application sets the height of the first positioning hole 3223 to be smaller than the height of the first cross beam 31, so that the height of the combined pipe 321 is smaller than the height of the first cross beam 31, and the height of the second cross beam 32 is smaller than the height of the first cross beam 31.

[0052] The height of the combined tube 321 from the ground can be affected by a variety of different ways of arranging the combined tube 321 and the combined bracket 322 in the second cross beam 32, wherein the height of the combined tube 321 from the ground can be affected by arranging the position of the first positioning hole 3223. The height of the first positioning hole 3223 from the ground is set to be smaller than the height of the first cross beam 31, that is, the height of the combined tube 321 from the ground is smaller than the height of the first cross beam 31, that is, part of the space can be left between the first longitudinal beam 20 and the second longitudinal beam 21, and at least part of the battery pack 50 can be accommodated.

[0053] Please continue reading Figure 1 and Figure 3 In some embodiments, the first longitudinal beam 20 and the second longitudinal beam 21 include a longitudinal beam body 23 and two enclosures 24 that are relatively arranged. The enclosures 24 are arranged between the longitudinal beam bodies 23 and vertically arranged on both sides of the longitudinal beam bodies 23. The connecting plates 3222 are arranged between the enclosures 24. The connecting plates 3222 are fixedly connected to the enclosures 24 through second positioning holes 3224. The longitudinal beam body 23, the enclosures 24, the connecting plates 3222 and the bracket body 3221 are combined to form an annular embracing structure 25.

[0054] In these embodiments, in the vehicle frame 10 provided in the embodiments of the present application, the second cross beam 32 forms an annular embracing structure 25 with the first longitudinal beam 20 and the second longitudinal beam 21 through the connecting plate 3222, which leaves some space between the first longitudinal beam 20 and the second longitudinal beam 21 while meeting the torsional resistance of the vehicle frame 10.

[0055] The connecting plate 3222 is fixedly connected to the enclosure 24 through the second positioning hole 3224. The connecting plate 3222, the bracket body 3221, the longitudinal beam body 23 and the enclosure 24 form a double C-shaped nested structure. The connecting plate 3222 is arranged between the enclosures 24 to form an annular embracing structure 25. Even if the second cross beam 32 is configured as a combined bracket 322 and a combined tube 321, and is not reinforced with a C-shaped connector like the first cross beam 31, the torsional resistance of the second cross beam 32 can still meet the torsional resistance requirements of the frame 10. While leaving some space between the first longitudinal beam 20 and the second longitudinal beam 21, the second cross beam 32 forms an annular embracing structure 25 with the first longitudinal beam 20 and the second longitudinal beam 21 through the connecting plate 3222, which can meet the torsional resistance requirements of the frame 10.

[0056] Please continue reading Figure 3 In some embodiments, the combined tube 321 is welded to the bracket body 3221 through the first positioning hole 3223 .

[0057] In these embodiments, in the vehicle frame 10 provided in the embodiments of the present application, the combined pipe 321 is welded to the bracket body 3221 after passing through the first positioning hole 3223 to form a fixed connection, and the connection effect is better.

[0058] Please continue reading Figure 3 In some embodiments, the enclosure 24 includes a plurality of reserved holes that pass through the enclosure 24 , and the connecting plate 3222 is riveted to the plurality of reserved holes of the enclosure 24 through the second positioning hole 3224 .

[0059] In these embodiments, when the combined bracket 322 is fixedly connected to the longitudinal beam of the frame 10 provided in the embodiment of the present application through the connecting plate 3222, the connecting plate 3222 is fixedly connected to the plurality of reserved holes of the enclosure 24 through the second positioning hole 3224 by riveting, and the fixed connection effect is better than other fixed connection methods.

[0060] See also Figure 3 In some embodiments, the vehicle frame 10 is further provided with a storage box 40 , which is arranged on a portion of the first longitudinal beam 20 fixedly connected to the second cross beam 32 and on a side of the second longitudinal beam 21 away from the second cross beam 32 .

[0061] In these embodiments, the vehicle frame 10 provided in the embodiments of the present application maximizes the functional space utilization by arranging the storage box 40 at the original location of the battery pack 50 .
