Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, specifically relating to a subframe mounting assembly, a subframe assembly, and a vehicle. Background Technology

[0002] The front and rear subframes are indispensable key components of a vehicle, and their importance is self-evident. To install these subframes, mounting brackets are required. Subframe mounting structures in related technologies involve the assembly and welding of multiple parts or their mechanical connections to form a single assembly. Therefore, the design must consider the connection processes and structural strength between these parts from the outset. Furthermore, the assembly process must be taken into account during assembly, which not only complicates the manufacturing process but also introduces safety hazards related to the strength and rigidity of the joints due to the numerous connection points.

[0003] like Figure 1 and Figure 2 As shown, in related technologies, the subframe mounting bracket is welded together using a steel plate stamping process (comprising the left / right subframe mounting plates, front elephant leg support plates, upper / lower elephant leg support plates, etc.). The assembly is joined together via welds and structural adhesive to meet installation and performance requirements. Figure 1 and Figure 2 As shown, this structure has a large number of connecting parts, which are connected by welding, resulting in low production efficiency. Furthermore, the numerous weld points affect its structural strength and the effectiveness of energy transfer. Summary of the Invention

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] like Figures 3 to 5 As shown, the subframe mounting assembly of this invention includes: a frame body 1 and a mounting part 2 that are sequentially connected and integrally formed, the frame body 1 being along a first direction (e.g., Figure 3 The mounting part 2 extends along the second direction (e.g., vertical direction) and extends along the vertical direction. Figure 3 Extending in the left-right direction, the mounting part 2 is connected to the subframe body, the frame 2 is connected to the vehicle body frame, the frame body has a first cavity 3, and the mounting part has a second cavity 4.

[0031] The first reinforcing rib 5 and the second reinforcing rib 6 are connected to the frame 1 and are provided in the first cavity 3. The second reinforcing rib 6 are connected to the mounting part 2 and are provided in the second cavity 4.

[0032] First reinforcing rib 5 First reinforcing rib 5 Second reinforcing rib 6 Second reinforcing rib 6

[0033] Specifically, such as Figure 3 and Figure 4 As shown, the mounting part 2 and the frame 1 are integrally formed by die casting or casting. The frame 1 extends vertically, and the mounting part 2 extends horizontally. The left side of the mounting part 2 is connected to the right end face of the frame 1, and the lower end face of the mounting part 2 is roughly flush with the lower end face of the frame 1. Multiple independent chambers 3 are evenly distributed inside the frame 1 and the mounting part 2.

[0034] The frame 13 may be provided with multiple first reinforcing ribs 5, or the frame 1 may be provided with first reinforcing ribs 5 in some positions and the remaining parts may not be provided with first reinforcing ribs 5. The mounting part 2 may be provided with second reinforcing ribs 6, or the mounting part 2 may be provided with second reinforcing ribs 6 in some positions and the remaining parts may not be provided with second reinforcing ribs 6.

[0035] The subframe mounting assembly of this invention integrates multiple original components into a single molded frame 1 and mounting section 2, thereby improving the assembly efficiency and structural strength of the subframe. By providing a first cavity 3 and a second cavity 4 on the frame 1 and mounting section 2, the overall weight of the mounting assembly can be reduced, absorbing energy during a collision. The first reinforcing rib 5 is provided in the first cavity 3, and the second reinforcing rib 6 is provided in the second cavity 4, which improves the structural strength of the mounting assembly and provides a force transmission path, effectively transferring energy during a collision.

[0036] In some embodiments, the frame 1 includes an integrally formed first frame 11 and a second frame 12, the first frame 11 extending in a first direction, the second frame 12 extending in a third direction, and the mounting part 2 connected to the first frame 11.

[0037] Specifically, such as Figure 3 and Figure 4 As shown, the first frame 11 extends vertically, and the second frame 12 extends horizontally. The first frame 11 and the second frame 12 intersect each other to form a cross shape. The vertical dimension of the first frame 11 is greater than or equal to the horizontal dimension of the second frame 12. The mounting part 2 is connected to the first frame 11, and the left end face of the mounting part 2 is connected to the right end face of the first frame 11. By setting the first frame 11 extending vertically and the second frame 12 extending horizontally to form a cross shape, the structural strength of the frame 1 can be increased, and energy can be transferred more effectively.

[0038] In some embodiments, the first cavity 3 includes a first chamber 31 and a second chamber 32 that are independent of each other. The first chamber 31 is located inside the first frame 11, and the second chamber 32 is located inside the second frame 12. The first frame 11 includes a first plate 111, a second plate 112, a third plate 113, a fourth plate 114, and a partition 115. The first plate 111 has a first side and a second side in a third direction. The second plate 112 and the third plate are located on the first side and the second side of the first plate 111, respectively. In the first direction, the fourth plate 114 is located on the side of the first plate 111 away from the mounting part 2. The first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 are connected in sequence to form the first cavity 3. The partition 115 is disposed in the first cavity 3 to divide the first cavity 3 into the first chamber 31 and the second chamber 32 that are independent of each other.

[0039] Specifically, such as Figure 3 and Figure 4 As shown, the first chamber 31 and the second chamber 32 are arranged at intervals in the vertical direction. The first plate 111 extends in the vertical direction, the second plate 112 and the third plate 113 are arranged opposite each other in the front-back direction, and the fourth plate 114 is located above the first plate 111. The first plate 111, the second plate 112, the third plate 113 and the fourth plate 114 form a first cavity 3 that opens to the right. The partition 115 is located in the first cavity 3. The left end face of the partition 115 is connected to the right end face of the first plate 111. The partition 115 divides the first cavity 3 into the first chamber 31 and the second chamber 32.

[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 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 opposite to each other in a third direction. The first sub-frame 121 and the second sub-frame 122 each 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 a first direction. The sixth plate 1212 and the seventh plate 1213 are the first side and the second side of the fifth plate 1211, respectively. The eighth plate 1214 is located on the side of the fifth plate 1211 away from the first frame 11. The fifth plate 1211, the sixth plate 1212, the seventh plate 1213 and the eighth plate 1214 are connected in sequence to form a second chamber 32.

[0042] Specifically, such as Figure 3 and Figure 4As shown, the first sub-frame 121 and the second sub-frame 122 are symmetrically arranged in the front-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 located at the upper and lower ends of the fifth plate 1211. The eighth plate 1214 is located 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. It should be noted that the second chamber 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 the left and right 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, and the first sub-chamber 311 and the second sub-chamber 312 are arranged at a distance from each other in a first direction.

[0046] The second chamber 32 includes a third sub-chamber 321 and a fourth sub-chamber 322 that are independent of each other. The third sub-chamber 321 and the fourth sub-chamber 322 are arranged at a distance in the third direction, and the third sub-chamber 321 is adjacent to the front side of the vehicle frame relative to the fourth sub-chamber 322. The interior of the third sub-chamber 321 is hollow.

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

[0048] like Figure 4 As shown, the third sub-chamber 321 is hollow, meaning that the third sub-chamber 321 does not have the first reinforcing rib 5 inside. By setting up independent first sub-chambers 311, second sub-chambers 312, third sub-chambers 321 and fourth sub-chambers 322, and by not having the first reinforcing rib 5 inside the third sub-chamber 321, it can better crumple up in the event of a head-on collision, thereby absorbing the energy generated by the vehicle collision.

[0049] In some embodiments, the number of first reinforcing ribs 5 in the first sub-cavity 321 is multiple, the first reinforcing ribs 5 in the first sub-cavity 321 extend in a third direction, and the multiple first reinforcing ribs 5 in the first sub-cavity 321 are spaced apart along a 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 5 are arc-shaped ribs recessed toward the interior of the first cavity 3.

[0050] Specifically, such as Figure 4 As shown, the first reinforcing rib 5 is an arc-shaped rib that is recessed towards the interior of the cavity 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 that is recessed towards the interior of the chamber 3. Setting the first reinforcing rib 5 and the second reinforcing rib 6 as arc-shaped ribs can better facilitate energy transfer, improve the structural strength inside the chamber 3, and thus improve the structural strength of the entire mounting assembly. Furthermore, compared to rectangular ribs, the recessed arc-shaped ribs eliminate the weight of the recessed portion, which helps reduce the weight of the reinforcing ribs and the entire mounting assembly.

[0051] The first reinforcing rib 5 in the first sub-chamber 321 extends 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 arranged at intervals in the vertical direction. It should be noted that the number of first reinforcing ribs 5 can also be three or four. The specific number can 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 from the third sub-chamber 321 to the fourth sub-chamber 322 and improving the energy transfer effect.

[0053] In some embodiments, the number of first reinforcing ribs 5 in the second chamber 32 is multiple, and the multiple first reinforcing ribs 5 in the second chamber 32 are arranged in a cross pattern.

[0054] Specifically, such as 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 vertical direction, and the other extends in the horizontal direction. The two first reinforcing ribs 5 are arranged in a cross shape. By setting two second reinforcing ribs 6 arranged in a cross shape in the second chamber 32, the overall rigidity of the frame 1 can be improved.

[0055] In some embodiments, the number of first reinforcing ribs 5 in the fourth sub-chamber 322 is multiple, the first reinforcing ribs 5 in the fourth sub-chamber 322 extend in a third direction, and the multiple first reinforcing ribs 5 in the fourth sub-chamber 322 are spaced apart along a first direction, and / or, on a projection plane parallel to the first direction, at least one of the multiple first reinforcing ribs 5 in the fourth sub-chamber 322 is in the same plane as at least one of the multiple first reinforcing ribs 5 in the first sub-chamber 321.

[0056] Specifically, such as Figure 4 As shown, the first reinforcing rib 5 in the first sub-chamber 321 extends 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 arranged at intervals in the vertical direction. It should be noted that the number of first reinforcing ribs 5 can also be three or four. 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 transmitted from the first sub-chamber 321 to the vehicle frame and improving the energy transfer effect.

[0058] Optionally, such as Figure 4 As shown, on a projection plane parallel to the vertical direction, at least one of the multiple first reinforcing ribs 5 in the fourth sub-chamber 322 is on the same plane as at least one of the multiple first reinforcing ribs 5 in the first sub-chamber 321. For example, when there are two first reinforcing ribs 5 in the fourth sub-chamber 322, and also two first reinforcing ribs 5 in the first sub-chamber 321, the upper first reinforcing rib 5 in the fourth sub-chamber 322 and the lower first reinforcing rib 5 in the first sub-chamber 321 are positioned in the same vertical 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 on the same straight line, which facilitates the transfer of energy between the first sub-chamber 321 and the fourth sub-chamber 322.

[0059] In some embodiments, the subframe mounting assembly further includes a plurality of connecting portions 7 adapted to be connected to the vehicle frame, and the plurality of connecting portions 7 are respectively disposed around the first frame 11 and the second frame 12.

[0060] Specifically, such as Figure 3 and Figure 4As shown, there are four connecting parts 7, located on the front and rear sides of the first frame 11 and 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 intersect. The outer wall surface of the connecting part 7 is roughly flush with the outer wall surfaces of the first frame 11 and the second frame 12. The connecting part 7 has connecting holes through which bolts connect the connecting part 7 to the vehicle frame. By setting the connecting parts 7, not only can the connection stability between the subframe mounting assembly and the vehicle frame be improved, but the energy generated by a collision can also be better transferred to the vehicle frame.

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

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

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

[0064] For example, the mounting part 2 may also be surrounded by a flange 22, which is connected to the connecting part 7 located below the second frame 12. The flange 22 can meet the crushing requirements in the event of a head-on collision and can reduce weight.

[0065] The subframe assembly of this invention includes: a subframe body and a mounting assembly, wherein the subframe body is connected to the mounting assembly, and the mounting assembly is the subframe mounting assembly of any of the above embodiments.

[0066] The subframe assembly of this invention, by employing the subframe mounting component described in the above embodiment, integrates the original mounting component formed by combining multiple parts into a single molded frame 1 and mounting part 2, thereby improving the assembly efficiency and structural strength of the subframe. By providing independent chambers 3 on the frame 1 and mounting part 2, the overall weight of the mounting component can be reduced, absorbing energy during a collision. Reinforcing ribs within the chambers 3 improve the structural strength of the mounting component and provide a force transmission path, effectively transferring energy during a collision.
