[0040] It should be noted that the first plate 111 , the second plate 112 , the third plate 113 , the fourth plate 114 and the partition plate 115 are integrally formed.

[0041] In some embodiments, the second frame includes a first sub-frame 121 and a second sub-frame 122, the first sub-frame 121 and the second sub-frame 122 are respectively connected to the first frame 11, and the first sub-frame 121 and the second sub-frame 122 are arranged relative to each other in a third direction, the first sub-frame 121 and the second sub-frame 122 both include a fifth plate 1211, a sixth plate 1212, a seventh plate 1213 and an eighth plate 1214, the fifth plate 1211 is connected to the first plate 111, the fifth plate 1211 has a first side and a second side in the first direction, the sixth plate 1212 and the seventh plate 1213 are respectively on the first side and the second side of the fifth plate 1211, the eighth plate 1214 is located on the side of the fifth plate 1211 away from the first frame 11, and the fifth plate 1211, the sixth plate 1212, the seventh plate 1213 and the eighth plate 1214 are sequentially connected to form a second chamber 32.

[0042] Specifically, Figure 3 and Figure 4As shown, the first sub-frame 121 and the second sub-frame 122 are symmetrically arranged in the front-to-back direction and both are connected to the first frame 11, the fifth plate 1211 is connected to the first plate 111, the sixth plate 1212 and the seventh plate 1213 are respectively arranged at the upper and lower ends of the fifth plate 1211, and the eighth plate 1214 is arranged on the side of the fifth plate away from the first frame 11.

[0043] The fifth plate 1211, the sixth plate 1212, the seventh plate 1213 and the eighth plate 1214 form a second chamber 32 with an opening facing the right side. It should be noted that the second chambers 32 in the first sub-frame 121 and the second sub-frame 122 have the same orientation, or the second chamber 32 in the second sub-frame 122 has openings at both ends.

[0044] Optionally, the fifth plate 1211, the sixth plate 1212, the seventh plate 1213 and the eighth plate 1214 are integrally formed, or the first plate 111, the second plate 112, the third plate 113, the fourth plate 114, the partition 115, the fifth plate 1211, the sixth plate 1212, the seventh plate 1213 and the eighth plate 1214 are integrally formed.

[0045] In some embodiments, the first chamber 31 includes a first sub-chamber 311 and a second sub-chamber 312 that are independent of each other. The first sub-chamber 311 and the second sub-chamber 312 are spaced apart in the first direction.

[0046] The second chamber 32 includes a third sub-chamber 321 and a fourth sub-chamber 322 which are independent of each other. The third sub-chamber 321 and the fourth sub-chamber 322 are spaced apart in the third direction, and the third sub-chamber 321 is adjacent to the front side of the vehicle body frame relative to the fourth sub-chamber 322. The third sub-chamber 321 is hollow inside.

[0047] Specifically, Figure 4 As shown, the first sub-chamber 311 and the second sub-chamber 312 are arranged in sequence in the up-down direction, and the third sub-chamber 321 and the fourth sub-chamber 322 are arranged in sequence in the front-back direction. The third sub-chamber 321 is adjacent to the front side of the vehicle body frame relative to the fourth sub-chamber 322. It should be noted that the front side of the vehicle body frame refers to the side that first contacts the collision object during a head-on collision of the vehicle.

[0048] like Figure 4 As shown, the third sub-chamber 321 is hollow inside, that is, the third sub-chamber 321 is not provided with the first reinforcing rib 5. By providing the first sub-chamber 311, the second sub-chamber 312, the third sub-chamber 321 and the fourth sub-chamber 322 independently of each other, and the third sub-chamber 321 is not provided with the first reinforcing rib 5, when a vehicle has a head-on collision, it can be better collapsed, thereby absorbing the energy generated by the vehicle collision.

[0049] In some embodiments, there are multiple first reinforcing ribs 5 in the first sub-chamber 321, the first reinforcing ribs 5 in the first sub-chamber 321 extend in the third direction, and the multiple first reinforcing ribs 5 in the first sub-chamber 321 are arranged at intervals along the first direction, and / or the first reinforcing ribs 5 are arc-shaped ribs recessed toward the interior of the first cavity 3, and / or the second reinforcing ribs are arc-shaped ribs recessed toward the interior of the first cavity 3.

[0050] Specifically, Figure 4 As shown, the first reinforcing rib 5 is an arc-shaped rib recessed toward the interior of the chamber 3, for example, the first reinforcing rib 5 is U-shaped. Figure 5 As shown, the second reinforcing rib 6 is an arc-shaped rib recessed toward the inside of the chamber 3. The first reinforcing rib 5 and the second reinforcing rib 6 are arranged as arc-shaped ribs, which can better realize the energy transmission, improve the structural strength inside the chamber 3, and thus improve the structural strength of the entire installation assembly. In addition, compared with rectangular ribs, the concave arc-shaped ribs save the weight of the concave part, which is conducive to reducing the weight of the reinforcing ribs and the weight of the entire installation assembly.

[0051] The first reinforcing ribs 5 in the first sub-chamber 321 extend in the front-to-back direction. There are two first reinforcing ribs 5 in the first sub-chamber 321. The two first reinforcing ribs 5 are spaced apart in the up-down direction. It should be noted that there may also be three or four first reinforcing ribs 5. The specific number may be selected according to actual needs.

[0052] like Figure 4 As shown, the front end of the first reinforcing rib 5 in the first sub-chamber 321 is connected to the wall of the third sub-chamber 321, and the rear end of the first reinforcing rib 5 in the first sub-chamber 321 is connected to the wall of the fourth sub-chamber 322, thereby effectively transferring the energy transferred from the third sub-chamber 321 to the fourth sub-chamber 322, thereby improving the effect of energy transfer.

[0053] In some embodiments, there are multiple first reinforcing ribs 5 in the second cavity 32, and the multiple first reinforcing ribs 5 in the second cavity 32 are cross-arranged.

[0054] Specifically, Figure 4 As shown, there are two first reinforcing ribs 5 in the second chamber 32, one of the two first reinforcing ribs 5 extends in the up-down direction, and the other first reinforcing rib 5 extends in the left-right direction, and the two first reinforcing ribs 5 are cross-arranged. By arranging two second reinforcing ribs 6 in a cross-arranged manner in the second chamber 32, the overall rigidity of the frame 1 can be improved.

[0055] In some embodiments, there are multiple first reinforcing ribs 5 in the fourth sub-chamber 322, the first reinforcing ribs 5 in the fourth sub-chamber 322 extend in the third direction, and the multiple first reinforcing ribs 5 in the fourth sub-chamber 322 are arranged at intervals along the first direction, and / or, on the projection plane parallel to the first direction, at least one first reinforcing rib 5 among the multiple first reinforcing ribs 5 in the fourth sub-chamber 322 and at least one first reinforcing rib 5 among the multiple first reinforcing ribs 5 in the first sub-chamber 321 are in the same plane.

[0056] Specifically, Figure 4 As shown, the first reinforcing ribs 5 in the first sub-chamber 321 extend in the front-to-back direction. The number of the first reinforcing ribs 5 in the first sub-chamber 321 is two, and the two first reinforcing ribs 5 are arranged at intervals in the up-down direction. It should be noted that the number of the first reinforcing ribs 5 can also be three or four, and the specific number can be selected according to actual needs.

[0057] like Figure 4 As shown, the front end of the first reinforcing rib 5 in the fourth sub-chamber 322 is connected to the wall of the first sub-chamber 321, and the rear end of the first reinforcing rib 5 in the fourth sub-chamber 322 is connected to the wall of the fourth sub-chamber 322, thereby effectively transferring the energy transferred from the first sub-chamber 321 to the vehicle body frame, thereby improving the effect of energy transfer.

[0058] Alternatively, if Figure 4 As shown, on the projection plane parallel to the up-down direction, at least one first reinforcing rib 5 among the plurality of first reinforcing ribs 5 in the fourth sub-chamber 322 is in the same plane as at least one first reinforcing rib 5 among the plurality of first reinforcing ribs 5 in the first sub-chamber 321. For example, when the number of the first reinforcing ribs 5 in the fourth sub-chamber 322 is two, and the number of the first reinforcing ribs 5 in the first sub-chamber 321 is also two, the first reinforcing rib 5 located at the top in the fourth sub-chamber 322 and the first reinforcing rib 5 located at the bottom in the first sub-chamber 321 are in the same position in the up-down direction. In other words, the first reinforcing rib 5 in the fourth sub-chamber 322 and the first reinforcing rib 5 in the first sub-chamber 321 are in the same straight line, which is conducive to the energy transfer between the first sub-chamber 321 and the fourth sub-chamber 322.

[0059] In some embodiments, the sub-frame mounting assembly further includes a plurality of connection portions 7 , which are suitable for being connected to the vehicle body frame, and the plurality of connection portions 7 are respectively disposed around the first frame body 11 and the second frame body 12 .

[0060] Specifically, Figure 3 and Figure 4As shown, there are four connecting parts 7, which are respectively arranged on the front and rear sides of the first frame 11, and the four connecting parts 7 are located on the upper and lower sides of the second frame 12. In other words, the four connecting parts 7 are located at the four corners where the first frame 11 and the second frame 12 meet. The outer wall surface of the connecting part 7 is substantially flush with the outer wall surface of the first frame 11 and the second frame 12. The connecting part 7 is provided with a connecting hole, and a bolt passes through the connecting hole to connect the connecting part 7 to the vehicle body frame. By providing the connecting part 7, not only can the connection stability between the subframe mounting assembly and the vehicle body frame be improved, but also the energy generated by the collision can be better transferred to the vehicle body frame.

[0061] In some embodiments, a leakage hole 21 is provided at the bottom of the mounting portion 2 .

[0062] Specifically, Figure 5 As shown, the mounting portion 2 also has a cavity 3 inside, and second reinforcing ribs 6 are distributed at intervals in the cavity 3 inside the mounting portion 2. By arranging the second reinforcing ribs 6 inside the mounting portion 2, the rigidity of the mounting portion 2 can be improved, thereby improving the connection stability between the mounting portion 2 and the sub-frame body.

[0063] It should be noted that the cavity inside the mounting portion 2 is a sealed cavity. In order to prevent liquid from accumulating in the frame 1 and the mounting portion 2 during the vehicle painting process, a leakage hole 21 is provided at the bottom of the mounting portion 2 to discharge the liquid.

[0064] For example, the mounting portion 2 may be surrounded by a flange 22, and the flange 22 is connected to the connecting portion 7 located below the second frame 12. The flange 22 can meet the collapse requirements during a head-on collision and can reduce weight.

[0065] The sub-frame assembly of the embodiment of the present invention comprises: a sub-frame body and a mounting assembly, wherein the sub-frame body is connected to the mounting assembly, and the mounting assembly is the sub-frame mounting assembly of any one of the above embodiments.

[0066] The sub-frame assembly of the embodiment of the present invention adopts the sub-frame mounting assembly of the above embodiment, and the mounting assembly formed by the original combination of multiple parts is integrated into an integrally formed frame 1 and mounting portion 2, so that the assembly efficiency and structural strength of the sub-frame can be improved. By providing independent chambers 3 on the frame 1 and the mounting portion 2, the overall weight of the mounting assembly can be reduced, and the ability to absorb collision can be reduced. By providing reinforcing ribs in the chamber 3, the structural strength of the mounting assembly can be improved, and a force transmission path can be provided, so that energy can be effectively transmitted in the event of a collision.
