[0040] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0041] The subframe 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0042] like Figure 1-Figure 10 As shown, the subframe 1 according to the embodiment of the present invention includes a plurality of longitudinal beams 100 .

[0043] A plurality of longitudinal beams 100 are disposed on opposite sides of the subframe 1 , and the longitudinal beams 100 are provided with a bracket mounting portion 150 and a control arm mounting portion 140 , which are arranged in the left-right direction, and the control arm mounting portion 140 is located outside the bracket mounting portion 150 .

[0044] The control arm mounting portion 140 is provided with a plurality of control arm mounting holes 141, and the central axis of the control arm mounting hole 141 extends from bottom to top in the vertical direction away from the bracket mounting portion 150. In addition, the control arm mounting portion 140 in this embodiment can be a front mounting point of the control arm 600.

[0045] The bracket mounting portion 150 is used to connect the intermediate bracket, the connecting bracket is used to connect the subframe 1 and the vehicle body, the control arm mounting portion 140 is used to connect the control arm 600, and the control arm 600 is used to connect the subframe 1 and the suspension system.

[0046] 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.

[0047] According to the sub-frame 1 of the embodiment of the utility model, by extending the central axis of the control arm mounting hole 141 in a direction away from the bracket mounting portion 150, that is, the control arm mounting hole 141 is deflected toward the outside of the sub-frame 1 relative to the vertical direction, so that the operating space for disassembling and assembling the control arm 600 can be far away from the mounting bracket 700. When the control arm 600 is connected to the control arm mounting portion 140, it is possible to avoid positional interference between the tool for installing the control arm 600 and the mounting bracket 700 or other structures of the sub-frame 1, and the disassembly and assembly space of the control arm 600 can be larger, which facilitates the disassembly and assembly of the control arm 600.

[0048] Moreover, by deflecting the control arm mounting hole 141 toward the outside of the subframe 1, even if the height of the powertrain of the vehicle is low, the powertrain will not completely block the control arm mounting hole 141, thereby avoiding interference between the powertrain and the disassembly and assembly space of the control arm 600, further ensuring that the control arm 600 can be normally disassembled and assembled, and making the operation more convenient.

[0049] In this way, the sub-frame 1 according to the embodiment of the utility model can increase the disassembly and assembly space of the control arm 600, avoid the position interference between the disassembly and assembly of the control arm 600 and other components, and the disassembly and assembly of the control arm 600 is more convenient.

[0050] In some specific embodiments of the present invention, Figure 6 As shown, the angle between the central axis of the control arm mounting hole 141 and the up-down direction is A, wherein the angle A satisfies: 15°≤A≤35°.

[0051] For example, the angle A between the central axis of the control arm mounting hole 141 and the up-down direction may be 15°, 20°, 25°, 30°, or 35°.

[0052] Such arrangement can, on the one hand, prevent the angle A between the central axis of the control arm mounting hole 141 and the up-down direction from being too small, so as to ensure that the control arm mounting hole 141 can be deflected outwardly of the sub-frame 1 at a larger angle, and more effectively prevent the disassembly and assembly space of the control arm 600 from interfering with the mounting bracket 700 or the powertrain; on the other hand, it can prevent the angle A between the central axis of the control arm mounting hole 141 and the up-down direction from being too large, which is beneficial to simplifying the structure of the control arm mounting portion 140, so as to facilitate the processing of the control arm mounting hole 141 when producing the longitudinal beam 100, and can ensure that the structural strength of the control arm mounting portion 140 is high, and the connection between the control arm 600 and the longitudinal beam 100 is more reliable.

[0053] In some specific embodiments of the present invention, Figure 5 and Figure 6 As shown, the longitudinal beam 100 includes an upper longitudinal beam panel 110 , a lower longitudinal beam panel 120 , and a longitudinal beam reinforcement panel 130 .

[0054] The lower longitudinal beam plate 120 is connected to the bottom of the upper longitudinal beam plate 110, and the lower longitudinal beam plate 120 and the upper longitudinal beam plate 110 jointly define a reinforcement cavity 112, the longitudinal beam reinforcement plate 130 is disposed in the reinforcement cavity 112 and connected to the upper longitudinal beam plate 110, at least a portion of the longitudinal beam reinforcement plate 130 is disposed at the control arm mounting portion 140, and the upper longitudinal beam plate 110, the lower longitudinal beam plate 120 and the longitudinal beam reinforcement plate 130 jointly construct a control arm mounting hole 141.

[0055] For example, a part of the upper longitudinal beam plate 110, a part of the lower longitudinal beam plate 120, and the longitudinal beam reinforcement plate 130 can be stacked and spaced apart, and through holes can be respectively formed on the upper longitudinal beam plate 110, the lower longitudinal beam plate 120, and the longitudinal beam reinforcement plate 130 along the thickness direction of the longitudinal beam reinforcement plate 130, and a plurality of through holes are coaxially arranged to jointly form a control arm mounting hole 141.

[0056] In this way, the cross-section of the longitudinal beam 100 can be roughly in the shape of a Chinese character 'Ri' (日), and thus the structural strength of the longitudinal beam 100 can be greatly improved by using the longitudinal beam reinforcement plate 130, thereby improving the collision energy absorption effect of the longitudinal beam 100, and the anti-collision ability of the subframe 1 is stronger.

[0057] Furthermore, as Figure 1 , Figure 2 and Figure 4 shown, the upper longitudinal beam plate 110 is provided with an avoidance groove 111 for avoiding the powertrain, and the avoidance groove 111 and the control arm mounting portion 140 are spaced apart along the length direction of the longitudinal beam 100. Wherein, 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 the side of the avoidance groove 111 away from the control arm mounting portion 140.

[0058] It can be understood that setting the avoidance groove 111 on the longitudinal beam 100 will cause a sudden change in the cross-sectional dimension of the longitudinal beam 100, thereby causing a decrease in the structural strength of the longitudinal beam 100. By setting the longitudinal beam reinforcement plate 130, the cross-section of the longitudinal beam 100 can be in the shape of a Chinese character 'Ri' (日), and thus the longitudinal beam reinforcement plate 130 can be used to make up for the loss of cross-sectional stiffness of the longitudinal beam 100 caused by setting the avoidance groove 111, that is, the structural strength of the longitudinal beam 100 can be improved by using the longitudinal beam reinforcement plate 130, thereby improving the collision energy absorption effect of the longitudinal beam 100.

[0059] Moreover, since the longitudinal beam reinforcement plate 130 extends from the control arm mounting portion 140 to the avoidance groove 111, the longitudinal beam reinforcement plate 130 can cover the control arm mounting portion 140 and the avoidance groove 111. In this way, the longitudinal beam reinforcement plate 130 can strengthen the structural strength of the positions where the control arm mounting portion 140 and the avoidance groove 111 are provided on the longitudinal beam 100 at the same time, with higher pertinence and can more effectively improve the structural strength of the longitudinal beam 100.

[0060] In some specific embodiments of the present invention, the longitudinal beam reinforcement plate 130 is provided with a middle reinforcing rib 131. Wherein, the middle reinforcing rib 131 can protrude from the side of the longitudinal beam reinforcement plate 130 facing the longitudinal beam 100.

[0061] 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 longitudinal beam 100.

[0062] In some specific embodiments of the present invention, Figure 6 As shown, the subframe 1 further includes a mounting sleeve 160 , and the mounting sleeve 160 can be used to connect and mount the control arm 600 .

[0063] The mounting sleeve 160 is inserted into the control arm mounting hole 141 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 the installation sleeve 160 can be 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 1-Figure 3 As shown, the subframe 1 further includes a first crossbeam 300 , both ends of which are respectively connected to the plurality of longitudinal beams 100 , and the first crossbeam 300 corresponds to the control arm mounting portion 140 in the length direction of the subframe 1 .

[0066] In this arrangement, not only can the first cross beam 300 be used to improve the connection strength between the plurality of longitudinal beams 100 so as to make the overall structural strength of the subframe 1 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 provided on the longitudinal beam 100, so that the structural strength of the control arm mounting portion 140 can be higher, thereby enabling the longitudinal beam 100 to be more reliably connected to the control arm 600.

[0067] In addition, a second avoidance groove 312 is provided at the left end of the first crossbeam 300, and the second avoidance groove 312 is used to avoid the power assembly. The second avoidance groove 312 and the avoidance groove 111 on the left longitudinal beam 100 can be used to avoid the housing of the transmission at the same time, so that the first crossbeam 300 will not interfere with the power assembly, and the structural setting is more reasonable.

[0068] Furthermore, if Figure 7 As shown, the first beam 300 includes an upper beam plate 310 and a lower beam plate 320 .

[0069] The upper cross beam plate 310 is formed with a first reinforcing rib 311 extending along the length direction of the upper cross beam plate 310 , and the lower cross beam plate 320 is formed with a second reinforcing rib 321 extending along the length direction of the lower cross beam plate 320 .

[0070] 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.

[0071] In addition, in order to avoid the second avoidance groove 312 , the first reinforcing rib 311 may be provided at the right end of the upper cross beam plate 310 . A plurality of second reinforcing ribs 321 may be provided, and the plurality of second reinforcing ribs 321 may be arranged at intervals along the length direction of the lower cross beam plate 320 .

[0072] 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.

[0073] In some specific embodiments of the present invention, Figure 7 As shown, the subframe 1 further includes a suspension bracket 330 .

[0074] 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.

[0075] 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.

[0076] 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 .

[0077] The second cross beam 400 is located at the rear side of the first cross beam 300 and the two ends of the second cross beam 400 are respectively connected to the plurality of longitudinal beams 100 . The cross beam reinforcement plate 500 is disposed below the first cross beam 300 and the second cross beam 400 and the two ends of the cross beam reinforcement plate 500 are respectively connected to the first cross beam 300 and the second cross beam 400 .

[0078] 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. In this way, the first cross beam 300 and the second cross beam 400 can be used to improve the connection strength of multiple longitudinal beams 100, 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.

[0079] In addition, if Figure 1-Figure 3 As shown, 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. In addition, the cross beam reinforcement plate 500 can also protect the steering gear above it.

[0080] In addition, both sides of the transverse reinforcement plate in the left and right directions can be bent upward to form flanges 520, which can improve the structural strength of the transverse reinforcement plate, so that the supporting rigidity of the transverse reinforcement part is greater, and the connection area between the transverse reinforcement plate and the first crossbeam 300 and the second crossbeam 400 can be larger, and the connection is more stable and reliable.
