[0027] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0028] Reference below Figure 1-Figure 5 The subframe assembly 100 according to an embodiment of the present invention is described, and the subframe assembly 100 is applied to a vehicle, for example, a rear subframe of an electric vehicle.

[0029] like Figure 1-Figure 5 As shown, according to the utility model, the subframe assembly 100 includes: a longitudinal beam 10, a cross beam 20 and a control arm bracket 30, the longitudinal beams 10 are arranged opposite to each other in the transverse direction, the cross beam 20 is connected between two opposite longitudinal beams 10 and connected to the rear of the longitudinal beams 10, the control arm bracket 30 is connected to the longitudinal beam 10, the control arm bracket 30 is connected to the front side of the cross beam 20, and an avoidance space for the avoidance drive structure is formed below the control arm bracket 30.

[0030] It can be understood that the longitudinal beam 10, the cross beam 20 and the control arm bracket 30 constitute the main structure of the sub-frame assembly 100, the longitudinal beams 10 are arranged at intervals on the left and right, the cross beam 20 is located between the longitudinal beams 10 on the left and right sides, and the left end of the cross beam 20 is connected to the left longitudinal beam 10, and the right end of the cross beam 20 is connected to the right longitudinal beam 10, so that the cross beam 20 and the longitudinal beam 10 can form a frame structure, thereby improving the overall structural strength of the sub-frame assembly 100 and facilitating the installation of other components on the sub-frame assembly 100.

[0031] The cross beam 20 is located at the rear of the longitudinal beam 10. This arrangement can save space in front of the cross beam 20, thereby increasing the space in the middle of the sub-frame assembly 100, and making it easier to install other components on the sub-frame assembly 100. The control arm bracket 30 is connected to the side of the longitudinal beam 10. This arrangement allows the control arm bracket 30 to limit the control arm, thereby facilitating the control arm to be set on the sub-frame assembly 100, and thus ensuring the stability of the vehicle's suspension system.

[0032] In addition, the rear side of the control arm bracket 30 is connected to the front side of the cross beam 20. This arrangement can save space between the control arm bracket 30 and the cross beam 20, and can also connect the longitudinal beam 10, the cross beam 20 and the control arm bracket 30 to each other, thereby improving the overall structural strength of the subframe assembly 100, thereby improving the safety of the vehicle, and the control arm bracket 30 is connected to the longitudinal beam 10 at an angle. This arrangement can form an avoidance space under the control arm bracket 30, and the avoidance space can avoid the drive structure, thereby facilitating the installation of the drive structure on the subframe assembly 100, and the drive structure does not affect the installation and layout of other components, thereby meeting the space layout requirements of the rear axle electric drive system.

[0033] Therefore, by arranging the cross beam 20 at the rear of the longitudinal beam 10 and the control arm bracket 30 at the front side of the cross beam 20, the longitudinal beam 10, the cross beam 20 and the control arm bracket 30 can be connected to each other, thereby improving the overall structural strength of the sub-frame assembly 100, and an avoidance space is formed under the control arm bracket 30. The avoidance space can avoid the drive structure, thereby facilitating the installation of the drive structure in the sub-frame assembly 100, and can also meet the space layout requirements of the rear axle electric drive system, thereby improving the performance of the vehicle.

[0034] Among them, Figure 1 , Figure 4 and Figure 5As shown, the control arm bracket 30 includes: a first side plate 31, a second side plate 32 and a front plate 33. The first side plate 31 and the second side plate 32 are respectively connected to the front side of the cross beam 20 and are arranged opposite to each other. The front plate 33 is connected between the first side plate 31 and the second side plate 32. The front plate 33 and the front side of the cross beam 20 are respectively provided with control arm mounting points 35. At least one of the front plate 33, the first side plate 31 and the second side plate 32 is connected to the longitudinal beam 10.

[0035] That is to say, the first side plate 31, the second side plate 32 and the front plate 33 constitute the main structure of the control arm bracket 30. The first side plate 31 and the second side plate 32 are arranged opposite to each other up and down, so that a frame structure can be formed between the first side plate 31 and the second side plate 32, thereby improving the overall structural strength of the control arm bracket 30. The rear sides of the first side plate 31 and the second side plate 32 are connected to the front side of the cross beam 20, so that the space between the longitudinal beam 10 and the cross beam 20 can be used, which is convenient for arranging other components in the subframe assembly 100. The front plate 33 is located on the front side of the first side plate 31 and the second side plate 32. Such an arrangement can form a cavity structure among the first side plate 31, the second side plate 32 and the front plate 33, thereby improving the overall structural strength of the control arm bracket 30. Moreover, the cross-sections of the first side plate 31, the second side plate 32 and the front plate 33 form a "U" shape, which is convenient for connecting the control arm bracket 30 with the longitudinal beam 10 and the cross beam 20, and can also improve the strength of the control arm bracket 30.

[0036] A control arm mounting point 35 is set at the front side of the front plate 33 and the cross beam 20. The control arm mounting point 35 can limit the control arm, so that the control arm can be installed on the control arm bracket 30, and then the control arm can be installed on the subframe assembly 100. The upper ends of the front plate 33, the first side plate 31 and the second side plate 32 are all connected to the longitudinal beam 10. The front plate 33 is connected to the inner surface of the longitudinal beam 10, the upper side of the first side plate 31 is connected to the upper surface of the longitudinal beam 10, the upper side of the second side plate 32 is connected to the lower surface of the longitudinal beam 10, the upper side of the front plate 33 is connected to the inner surface of the longitudinal beam 10, and the rear sides of the first side plate 31 and the second side plate 32 are connected to the cross beam 20. This arrangement can connect the control arm bracket 30, the cross beam 20 and the longitudinal beam 10 to each other, thereby improving the overall structural strength of the subframe assembly 100.

[0037] In addition, if Figure 1 , Figure 4 and Figure 5As shown, the first side plate 31 is located on the side of the second side plate 32 away from the center of the sub-frame assembly 100, and a clearance opening is formed at the lower part of the second side plate 32, so that the control arm can be avoided. It can be understood that the first side plate 31 is away from the center of the sub-frame assembly 100 relative to the second side plate 32, so that the first side plate 31 is located above the second side plate 32, and the first side plate 31 and the second side plate 32 are tilted relative to the cross beam 20 and the longitudinal beam 10, so that the connection strength between the control arm bracket 30, the cross beam 20 and the longitudinal beam 10 can be improved, the length of the second side plate 32 is less than the length of the first side plate 31, and the upper sides of the first side plate 31 and the second side plate 32 are both connected to the longitudinal beam 10, so that a notch is formed at the bottom of the second side plate 32, and the notch can be a clearance opening, and the control arm is installed on the control arm bracket 30, so that the clearance opening can avoid the control arm, thereby facilitating the arrangement and installation of the control arm. For example, the cross-section of the upper part of the first side panel 31, the second side panel 32 and the front panel 33 forms a "U" shape, and the cross-section of the upper part of the first side panel 31, the second side panel 32 and the front panel 33 forms an "L" shape. This facilitates the connection of the control arm bracket 30 with the longitudinal beam 10 and the cross beam 20, and can also improve the strength of the control arm bracket 30, thereby facilitating the installation of the control arm on the control arm bracket 30.

[0038] In addition, if Figure 1 and Figure 4 As shown, at least one of the front side surfaces of the front plate 33 and the cross beam 20 is provided with a first reinforcing plate 34. That is, the first reinforcing plate 34 is provided at the connection between the front plate 33 and the longitudinal beam 10, and the first reinforcing plate 34 is located at the outer side and lower side of the longitudinal beam 10. Such a configuration can enhance the connection strength between the control arm bracket 30, the longitudinal beam 10 and the cross beam 20, and can also reduce the stress at the upper end of the control arm bracket 30, thereby improving the overall strength and stiffness performance of the subframe assembly 100, and further improving the safety of the vehicle.

[0039] In addition, if Figure 3 and Figure 5As shown, the control arm mounting point 35 is a control arm mounting hole, and a through hole 21 is provided on the rear side of the cross beam 20. The control arm mounting hole corresponds to the through hole 21 in front and back, and the cross-sectional area of ​​the control arm mounting hole is smaller than the cross-sectional area of ​​the through hole 21. It can be understood that the control arm mounting point 35 is set as the control arm mounting hole, and the through hole 21 is provided on the cross beam 20. This arrangement allows the fastener to pass through the control arm mounting hole, and then pass through one end of the control arm and then connect with the cross beam 20, so that the control arm can be installed on the control arm bracket 30, and the rear side of the control arm bracket 30 can also be fitted with the front side of the cross beam 20, which is convenient for the arrangement of surrounding parts. In addition, the fastener is a bolt 40. When the bolt 40 passes through the control arm, a bushing 50 is provided on the outer periphery of the bolt 40. This arrangement is convenient for the installation of the bolt 40. The assembly and disassembly of the control arm bracket 30 can also improve the connection strength between the control arm bracket 30 and the control arm, thereby improving the overall structural strength of the subframe assembly 100. The control arm mounting hole and the through hole 21 are correspondingly arranged, and the cross-sectional area of ​​the control arm mounting hole is smaller than the cross-sectional area of ​​the through hole 21. This arrangement is convenient for the through hole 21 to limit and protect the bolt 40 after the bolt 40 passes through the control arm, thereby improving the space utilization rate between the control arm, the cross beam 20 and the longitudinal beam 10, and further realizing the lightweight design of the vehicle without adding other components.

[0040] In addition, if Figure 2 and Figure 5 As shown, the subframe assembly 100 further includes: a second reinforcing plate 36, which is respectively connected to the upper surface of the cross beam 20, the upper surface of the longitudinal beam 10 and the control arm bracket 30. In other words, the second reinforcing plate 36 is located on the upper surface of the cross beam 20, the upper surface of the longitudinal beam 10 and the control arm bracket 30, and such a configuration can enhance the connection strength between the control arm bracket 30, the longitudinal beam 10 and the cross beam 20, and can also reduce the stress on the upper end of the control arm bracket 30, thereby improving the overall strength and stiffness performance of the subframe assembly 100, and further improving the safety of the vehicle.

[0041] In addition, if Figure 2 As shown, a protrusion is provided on the second reinforcing plate 36, and a weight-reducing hole is provided on the protrusion. It can be understood that the upward protrusion is provided on the second reinforcing plate 36, so that the second reinforcing plate 36 can form an arch structure, thereby improving the connection strength between the control arm bracket 30, the longitudinal beam 10 and the cross beam 20, and the weight-reducing hole is provided on the protrusion, so that the weight of the second reinforcing plate 36 can be reduced, thereby achieving a lightweight design of the subframe assembly 100.

[0042] In particular, if Figure 1-Figure 5As shown, the lowest point of the control arm bracket 30 is not lower than the lowest point of the cross beam 20. This arrangement allows the lower end of the control arm bracket 30 to exceed the lower surface of the cross beam 20, thereby forming an escape space under the control arm bracket 30. The escape space can escape the drive structure, which makes it easier to install the drive structure in the subframe assembly 100 and can also meet the space layout requirements of the rear axle electric drive system, thereby improving the performance of the vehicle.

[0043] In addition, Figure 1-Figure 5 As shown, the control arm bracket 30 is an integrally formed metal bracket, which can enhance the connection strength between the control arm bracket 30, the longitudinal beam 10 and the cross beam 20, reduce the stress of the control arm bracket 30, and improve the overall structural strength and rigidity of the control arm bracket 30, thereby improving the overall strength and rigidity performance of the subframe assembly 100, and further improving the safety of the vehicle.

By arranging the crossbeam 20 at the rear of the longitudinal beam 10 and the control arm bracket 30 at the front side of the crossbeam 20, the longitudinal beam 10, the crossbeam 20 and the control arm bracket 30 can be connected to each other, thereby improving the overall structural strength of the subframe assembly 100, and an avoidance space is formed below the control arm bracket 30, and the avoidance space can avoid the drive structure, thereby facilitating the installation of the drive structure in the subframe assembly 100, and can also meet the space layout requirements of the rear axle electric drive system, thereby improving the performance of the vehicle.
