[0018] Preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of this application.

[0019] First, it should be noted that the directional terms such as top, bottom, upward, and downward mentioned in this article are defined relative to the directions shown in the various accompanying figures. These are relative concepts and therefore can vary depending on the location and usage of the feature. Therefore, these directional terms should not be construed as restrictive.

[0020] Furthermore, it should be noted that any single technical feature described or implied in the embodiments herein, or any single technical feature shown or implied in the accompanying drawings, can still be combined among these technical features (or their equivalents) to obtain other embodiments of this application not directly mentioned herein.

[0021] It should be noted that in different figures, the same reference numerals denote the same or substantially the same components.

[0022] Figure 1 and Figure 2 An embodiment of the suspension architecture component of this application is shown. For example... Figure 1 and Figure 2 As shown, the suspension frame assembly includes a housing 10, a base 20, an elastic element 30, a limiting element 40, and one or more connectors.

[0023] The housing 10 may define an interior cavity 11. The cavity 11 may have an inner wall, and the housing 10 has a predetermined wall thickness around the cavity 11. In the illustrated embodiment, the cavity 11 may have a generally trapezoidal cross-section. In one embodiment, the housing 10 may be a die-cast aluminum alloy.

[0024] The base 20 may be disposed within the cavity 11 and fixedly positioned relative to the cavity 11. In one embodiment, the position of the base 20 relative to the housing 10 is variable. The different positions of the base 20 will be described in detail below. In the illustrated embodiment, the base 20 may have a generally inverted trapezoidal profile, and the profile of the base 20 is adapted to be fitted into the interior of the cavity 11.

[0025] The elastic element 30 may be configured to be integrally connected to the base 20. In one embodiment, the elastic element 30 and the base 20 have a vulcanized connection. In one embodiment, the elastic element 30 may be formed from natural rubber through vulcanization to achieve a predetermined stiffness. In one embodiment, the elastic element 30 is a suspension spring. The center position of the suspension spring is the elastic center of the entire suspension frame assembly. Figure 1 and Figure 2 In the diagram, the elastic element 30 is shown only schematically to illustrate its approximate location. The center of the main spring suspension can be used for connection to a vehicle powertrain (not shown). The elastic element 30 can be connected to the connector 30. The connector 30 can be part of the main spring structure and connected to other components (not shown).

[0026] A limiting member 40 may be disposed between the base 20 and the inner wall of the housing 10. For example, a single limiting member 40 may be provided on each side of the base 20. Alternatively, a limiting member may be provided on one side of the base 20, while the other side may not have a limiting member. The dimensions of each limiting member 40 may be approximately the same or different. In the illustrated embodiment, each limiting member 40 has a generally trapezoidal cross-section to adapt to both the side of the base 20 and the inner wall of the housing 10. In one embodiment, there may be an interference fit between the limiting member 40 and the base 20. In another embodiment, there may be an interference fit between the limiting member 40 and the inner wall of the housing 10. In one embodiment, different thicknesses of the housing 10 may correspond to different dimensions of the limiting member 40. In other words, if different housing thicknesses are used, the corresponding dimensions of the limiting member 40 are different. Depending on actual needs, the dimensions of the limiting member 40 may be matched with the thickness of the housing 10 to position the base 20 in the desired location.

[0027] By setting different thicknesses of the housing 10 and using different limiting members 40, the position of the base 20 can be adjusted. Figure 1 The state shown is changed from the first state. For example, the position of the base 20 can be changed to... Figure 2 The second state is shown. By employing different housing thicknesses and other limiting elements, it is possible to fix the base 20 to even more positions. When the position of the base 20 changes, the position of the elastic element 30 changes accordingly. This causes the center of the suspension spring to change accordingly, thus adapting it to different vehicle powertrains.

[0028] The suspension frame assembly may also include one or more longitudinal beam interfaces. In the illustrated embodiment, bolt holes are provided at the lower part of the housing 10. These bolt holes are the longitudinal beam interfaces in the illustrated embodiment. Each bolt hole is adapted to a first bolt hole 101 and a second bolt hole 102 on the vehicle body longitudinal beam 100. In one embodiment, the first bolt hole 101 and the second bolt hole 102 are also referred to as longitudinal beam mounting points. The first connector 51 and the second connector 52 can be used to secure the suspension frame assembly to the vehicle body longitudinal beam 100. In practice, the number of connectors is not limited to the illustrated case, and more connectors may be used. In one embodiment, the connectors may be bolts.

[0029] This application also relates to a vehicle including the suspension frame assembly described above. A body longitudinal beam 100 may be provided on the vehicle, and bolt holes are provided on the body longitudinal beam 100. The bolt holes at the lower part of the housing 10 may be configured to mate with the bolt holes on the body longitudinal beam 100 so as to secure the suspension frame assembly to the body longitudinal beam 100 via connectors.

[0030] Furthermore, the powertrain is connected to the suspension frame components, more specifically to the elastic element 30 and the base 20. In this configuration, the NTA line of the powertrain can be located at the elastic center of the elastic element 30, ensuring the powertrain is securely fixed in place. The closer the elastic center is to the NTA line, the better the vibration isolation performance of the elastic element 30. Therefore, this arrangement also results in improved NVH performance, thereby enhancing the user experience.

[0031] Furthermore, by changing the position of the base 20, the suspension architecture component of this application can adapt a single vehicle platform to different powertrains. This structure helps save development costs and improves cost efficiency. The elastic element 30 can be the same or different for different vehicles.

[0032] The suspension architecture component and vehicle of this application have advantages such as simple structure, ease of use, low cost, and convenient maintenance. By adopting the suspension architecture component and vehicle of this application, the operational efficiency of the vehicle platform can be effectively improved.

The scope of this application is defined by the claimed technical solution, but includes other instances that would occur to those skilled in the art. Such other instances shall be considered to fall within the scope of protection defined by the claimed technical solution, provided that they include structural elements that are not different from the literal language of the claimed technical solution, or that they include equivalent structural elements that are not substantially different from the literal language of the claimed technical solution.
