[0039] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0040] The subframe 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] like Figure 1-Figure 9As shown, the subframe 1 according to the embodiment of the present invention includes a first longitudinal beam 100 and a second longitudinal beam 200 .

[0042] The first longitudinal beam 100 and the second longitudinal beam 200 are disposed at opposite sides of the sub-frame 1 , and at least one of the first longitudinal beam 100 and the second longitudinal beam 200 is provided with a first avoidance groove 111 , and the first avoidance groove 111 is used to avoid the power assembly.

[0043] In order to lower the height of the vehicle, it is usually necessary to lower the height of the vehicle's powertrain to avoid positional interference between the engine cover and the powertrain.

[0044] Among them, at least one of the first longitudinal beam 100 and the second longitudinal beam 200 is provided with the first avoidance groove 111, which means that the first longitudinal beam 100 and the second longitudinal beam 200 can both be provided with the first avoidance groove 111, or the first longitudinal beam 100 is provided with the first avoidance groove 111 and the second longitudinal beam 200 is not provided with the first avoidance groove 111, or the first longitudinal beam 100 is not provided with the first avoidance groove 111 and the second longitudinal beam 200 is provided with the first avoidance groove 111. In this way, the first longitudinal beam 100 and the second longitudinal beam 200 can be provided with the first avoidance groove 111 according to the actual assembly position of the power assembly, while ensuring that the first longitudinal beam 100 and the second longitudinal beam 200 can avoid the power assembly, the structural strength of the first longitudinal beam 100 and the second longitudinal beam 200 can also be ensured to be high.

[0045] In addition, the up-down direction in the drawings is the up-down direction of the subframe 1 mounted on the vehicle, the left-right direction is the left-right direction of the vehicle, and the front-back direction is the front-back direction of the vehicle.

[0046] According to the sub-frame 1 of the embodiment of the utility model, by providing the first avoidance groove 111 in at least one of the first longitudinal beam 100 and the second longitudinal beam 200, after the height of the powertrain is lowered, the portion of the powertrain occupying the sub-frame 1 can be located in the first avoidance groove 111, and then the first avoidance groove 111 can be used to avoid the powertrain, and the sub-frame 1 will not interfere with the powertrain in position, so as to facilitate lowering the height of the powertrain, thereby reducing the height of the entire vehicle, and after the height of the entire vehicle is lowered, the engine cover will not interfere with the powertrain, and the layout arrangement is more reasonable.

[0047] According to the embodiment of the utility model, the subframe 1 can avoid the power assembly, thereby preventing the power assembly from interfering with the subframe 1 after the power assembly is lowered in height, which is beneficial to reducing the height of the entire vehicle.

[0048] In some specific embodiments of the present invention, Figure 1 and Figure 2As shown, the first avoidance groove 111 is provided on the upper surface of the first longitudinal beam 100 on the side facing the second longitudinal beam 200 ; and / or the first avoidance groove 111 is provided on the upper surface of the second longitudinal beam 200 on the side facing the first longitudinal beam 100 .

[0049] In other words, the first avoidance groove 111 on the first longitudinal beam 100 is close to the inner side of the first longitudinal beam 100 , and the first avoidance groove 111 on the second longitudinal beam 200 is close to the inner side of the second longitudinal beam 200 .

[0050] Such an arrangement can not only make the position of the first avoidance groove 111 correspond to the power assembly, which is convenient for the assembly of the power assembly, but also the first avoidance groove 111 can be constructed only in a part of the width direction of the first longitudinal beam 100. In this way, in the width direction of the first longitudinal beam 100, the outer side of the first longitudinal beam 100 does not need to be provided with the first avoidance groove 111, that is, the height of the outer side of the first longitudinal beam 100 can still be relatively high, and the structural strength of the first longitudinal beam 100 at the position where the first avoidance groove 111 is provided can still be relatively high, so as to ensure that the supporting stability of the first longitudinal beam 100 can still meet the requirements.

[0051] Similarly, the second longitudinal beam 200 may also construct the first avoidance groove 111 only in a part of its width direction, so that in the width direction of the second longitudinal beam 200, the first avoidance groove 111 does not need to be set on the outer side of the second longitudinal beam 200, that is, the height of the outer side of the second longitudinal beam 200 can still be relatively high, and the structural strength of the second longitudinal beam 200 at the position where the first avoidance groove 111 is set can still be relatively high, so as to ensure that the supporting stability of the second longitudinal beam 200 can still meet the requirements.

[0052] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the first longitudinal beam 100 and the second longitudinal beam 200 are both provided with a first avoidance groove 111 , and the cross-sectional area of ​​the first avoidance groove 111 of the first longitudinal beam 100 is not less than the cross-sectional area of ​​the first avoidance groove 111 of the second longitudinal beam 200 .

[0053] The first longitudinal beam 100 can be located on the left side of the sub-frame 1, the second longitudinal beam 200 can be located on the right side of the sub-frame 1, and the first avoidance groove 111 on the first longitudinal beam 100 can be used to avoid the housing of the transmission of the powertrain, and the first avoidance groove 111 on the second longitudinal beam 200 can be used to avoid the oil pan of the engine.

[0054] For example, the cross-sectional area of the first avoidance groove 111 on the first longitudinal beam 100 may be equal to the cross-sectional area of the first avoidance groove 111 on the second longitudinal beam 200, or the cross-sectional area of the first avoidance groove 111 on the first longitudinal beam 100 may be greater than the cross-sectional area of the first avoidance groove 111 on the second longitudinal beam 200. Moreover, in some embodiments, the first avoidance groove 111 may be provided only on the first longitudinal beam 100, while the second longitudinal beam 200 is not provided with the first avoidance groove 111.

[0055] It should be noted that the interference amount between the housing of the transmission and the first longitudinal beam 100 is usually relatively large. By setting the cross-sectional area of the first avoidance groove 111 on the first longitudinal beam 100 to be relatively large, it is convenient to avoid the housing of the transmission, and the structural setting is more reasonable. Moreover, the cross-sectional area of the first avoidance groove 111 on the second longitudinal beam 200 can be relatively small, which can not only meet the avoidance of the oil pan, but also make the structural strength of the second longitudinal beam 200 higher.

[0056] In some specific embodiments of the present invention, as Figure 4 and Figure 5 shown, both the first longitudinal beam 100 and the second longitudinal beam 200 include an upper longitudinal beam plate 110, a lower longitudinal beam plate 120, and a longitudinal beam reinforcing plate 130.

[0057] The first avoidance groove 111 is provided on the upper longitudinal beam plate 110. The lower longitudinal beam plate 120 is connected below the upper longitudinal beam plate 110, and the lower longitudinal beam plate 120 and the upper longitudinal beam plate 110 jointly define a reinforcing cavity 112. The longitudinal beam reinforcing plate 130 is provided in the reinforcing cavity 112 and connected to the upper longitudinal beam plate 110.

[0058] It can be understood that providing the first avoidance groove 111 on the first longitudinal beam 100 and the second longitudinal beam 200 will cause a sudden change in the cross-sectional dimensions of the first longitudinal beam 100 and the second longitudinal beam 200, thereby causing a decrease in the structural strength of the first longitudinal beam 100 and the second longitudinal beam 200.

[0059] By providing the longitudinal beam reinforcing plate 130, the cross-section of the first longitudinal beam 100 and the cross-section of the first longitudinal beam 100 can be approximately in the shape of a Chinese character 'Ri'. Furthermore, the longitudinal beam reinforcing plate 130 can be used to make up for the loss of cross-sectional stiffness caused by setting the first avoidance groove 111, that is, the longitudinal beam reinforcing plate 130 can be used to improve the structural strength of the first longitudinal beam 100 and the second longitudinal beam 200, thereby improving the collision energy absorption effect of the first longitudinal beam 100 and the second longitudinal beam 200 to improve the anti-collision performance of the subframe 1.

[0060] In some specific embodiments of the present invention, as Figure 1 、 Figure 2 and Figure 7As shown, the first longitudinal beam 100 and the second longitudinal beam 200 are both provided with a control arm mounting portion 140 , which is used to connect and fix the control arm 600 of the suspension system. The control arm mounting portion 140 and the first avoidance groove 111 are spaced apart along the length direction of the sub-frame 1 .

[0061] One end of the longitudinal beam reinforcement plate 130 is connected to the control arm mounting portion 140 , and the other end of the longitudinal beam reinforcement plate 130 extends to a side of the first avoidance groove 111 away from the control arm mounting portion 140 .

[0062] That is to say, the longitudinal beam reinforcement plate 130 extends from the control arm mounting portion 140 to the first avoidance groove 111, and the longitudinal beam reinforcement plate 130 can cover the control arm mounting portion 140 and the first avoidance groove 111, so that the longitudinal beam reinforcement plate 130 can simultaneously strengthen the structural strength of the positions where the control arm mounting portion 140 and the avoidance groove are set on the longitudinal beam, which is more targeted and can more effectively improve the structural strength of the longitudinal beam.

[0063] In addition, if Figure 5 As shown, the subframe 1 may further include a mounting sleeve 160, which is used to mount the control arm 600. The mounting sleeve 160 may be inserted into the swing arm mounting hole and connected to the upper longitudinal beam plate 110, the lower longitudinal beam plate 120 and the longitudinal beam reinforcement plate 130 respectively. One end of the mounting sleeve 160 abuts against the lower longitudinal beam plate 120 and the other end extends from the upper longitudinal beam plate 110.

[0064] Among them, the longitudinal beam reinforcement plate 130 can be first welded to the installation sleeve 160, then welded to the upper longitudinal beam plate 110, and finally welded to the lower longitudinal beam plate 120. In this way, the installation sleeve 160 can be welded to the upper longitudinal beam plate 110, the lower longitudinal beam plate 120 and the longitudinal beam reinforcement plate 130 at the same time, which is beneficial to improve the strength and rigidity of the control arm mounting part 140, so that the durability performance and vibration isolation and noise reduction level of the subframe 1 are greatly improved.

[0065] In some specific embodiments of the present invention, Figure 7 and Figure 8 As shown, the longitudinal beam reinforcement plate 130 is provided with a middle reinforcement rib 131. The middle reinforcement rib 131 may protrude from one side of the longitudinal beam reinforcement plate 130 facing the upper longitudinal beam.

[0066] The middle reinforcement rib 131 is disposed in the middle of the longitudinal beam reinforcement plate 130 in the width direction, and the middle reinforcement rib 131 extends from the other end of the longitudinal beam reinforcement plate 130 to at least the control arm mounting portion 140. In this way, the middle reinforcement rib 131 can be used to improve the structural strength of the longitudinal beam reinforcement plate 130, and the longitudinal beam reinforcement plate 130 is less likely to deform, so that the longitudinal beam reinforcement plate 130 can be used to more effectively strengthen the overall structural strength of the first longitudinal beam 100 and the second longitudinal beam 200.

[0067] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the subframe 1 further includes a first crossbeam 300 .

[0068] The first longitudinal beam 100 and the second longitudinal beam 200 are both provided with a control arm mounting portion 140 , and both ends of the first cross beam 300 are respectively connected to the first longitudinal beam 100 and the second longitudinal beam 200 , and the first cross beam 300 corresponds to the control arm mounting portion 140 in the length direction of the sub-frame 1 .

[0069] In this way, not only can the first cross beam 300 be used to improve the connection strength between the first longitudinal beam 100 and the second longitudinal beam 200, so that the overall structural strength of the subframe 1 is higher, but also the first cross beam 300 can be used to carry out targeted structural reinforcement of the position where the control arm mounting portion 140 is set on the first longitudinal beam 100 and the second longitudinal beam 200, so that the structural strength of the control arm mounting portion 140 can be higher, thereby enabling the first longitudinal beam 100 and the second longitudinal beam 200 to be more reliably connected to the control arm 600.

[0070] In addition, a second avoidance groove 312 is provided at one end of the first cross beam 300 adjacent to the first longitudinal beam 100, and the second avoidance groove 312 is used to avoid the power assembly. The second avoidance groove 312 and the first avoidance groove 111 on the first longitudinal beam 100 can be used to avoid the housing of the transmission at the same time, so that the first cross beam 300 will not interfere with the power assembly, and the structural setting is more reasonable.

[0071] Furthermore, if Figure 6 As shown, the first cross beam 300 includes an upper cross beam plate 310 and a lower cross beam plate 320 .

[0072] The second avoidance groove 312 is provided at one end of the upper cross beam plate 310 adjacent to the first longitudinal beam 100, and a first reinforcing rib 311 is formed at one end of the upper cross beam plate 310 adjacent to the second longitudinal beam 200, and second reinforcing ribs 321 are formed at both ends of the lower cross beam plate 320. Moreover, the first reinforcing rib 311 and the second reinforcing rib 321 both extend along the length direction of the first cross beam 300.

[0073] The first reinforcing rib 311 may be formed by the upper cross beam plate 310 being recessed in a direction close to the lower cross beam plate 320, and the second reinforcing rib 321 may be formed by the lower cross beam plate 320 being recessed in a direction close to the upper cross beam plate 310. The first reinforcing rib 311 may be provided at one third of the right side of the upper cross beam plate 310, and the second reinforcing rib 321 may be provided at one third of the left side and one third of the right side of the lower cross beam plate 320, respectively.

[0074] By setting the first reinforcing rib 311 and the second reinforcing rib 321, the first reinforcing rib 311 can improve the structural strength of the upper beam plate 310, and the second reinforcing rib 321 can improve the structural strength of the lower beam plate 320, thereby improving the bending stiffness of the first beam 300. The first beam 300 has a higher structural strength, which is beneficial to improving the vibration isolation and noise reduction level of the suspension bracket 330.

[0075] In some specific embodiments of the present invention, Figure 6 As shown, the subframe 1 further includes a suspension bracket 330 .

[0076] The suspension bracket 330 is connected between the upper beam plate 310 and the lower beam plate 320 and is located in the middle of the length direction of the first beam 300 , and approaches the middle of the first beam 300 along the length direction of the first beam 300 , and the height of the first beam 300 gradually increases.

[0077] That is to say, along the length direction of the first cross beam 300, the first cross beam 300 is constructed into a shape that is high in the middle and low at both ends, that is, the cross-sectional height in the middle of the length direction of the first cross beam 300 is the highest, and the suspension bracket 330 is wrapped between the upper cross beam plate 310 and the lower cross beam plate 320 and is located at the highest position of the cross section of the first cross beam 300, thereby ensuring the strength and rigidity of the connection between the first cross beam 300 and the suspension bracket 330, and the connection of the suspension bracket 330 is more stable and reliable.

[0078] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the subframe 1 further includes a second cross beam 400 and a cross beam reinforcement plate 500 .

[0079] The second cross beam 400 is located at the rear side of the first cross beam 300 and is connected to the first longitudinal beam 100 and the second longitudinal beam 200 respectively. The cross beam reinforcement plate 500 is arranged below the first cross beam 300 and the second cross beam 400, and both ends of the cross beam reinforcement plate 500 are connected to the first cross beam 300 and the second cross beam 400 respectively.

[0080] For example, the two ends of the cross beam reinforcement plate 500 can be connected to the middle of the first cross beam 300 and the middle of the second cross beam 400 respectively, so that the first cross beam 300 and the second cross beam 400 can be used to improve the connection strength of the first longitudinal beam 100 and the second longitudinal beam 200, and the cross beam reinforcement plate 500 can improve the strength and rigidity of the second cross beam 400 in the front-to-back direction, so as to make the overall structural strength of the subframe 1 higher.

[0081] In addition, the cross beam reinforcement plate 500 is provided with a plurality of third reinforcement ribs 510, which extend in the front-rear direction and are arranged at intervals in the left-right direction, so that the cross beam reinforcement plate 500 itself can have a higher structural strength, that is, the cross beam reinforcement plate 500 has sufficient supporting rigidity, and the cross beam reinforcement plate 500 can more effectively improve the connection strength between the first cross beam 300 and the second cross beam 400. Moreover, the cross beam reinforcement plate 500 can also protect the steering gear above it.

[0082] In addition, both sides of the beam reinforcement plate 500 in the left and right directions can be bent upward to form flanges 520, which can improve the structural strength of the beam reinforcement plate 500, so that the supporting rigidity of the lateral reinforcement part is greater, and the connection area between the beam reinforcement plate 500 and the first beam 300 and the second beam 400 can be larger, and the connection is more stable and reliable.
