[0016] Furthermore, the vertical plate is provided with an outwardly protruding connecting post, and the vertical plate is provided with a downwardly protruding connecting block, and the connecting post and the connecting block are detachably connected.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] The subframe assembly described in this utility model connects the powertrain and the subframe together through a first connecting part on the powertrain bracket, which facilitates the installation of the powertrain on the subframe. The subframe and the powertrain bracket are connected to the vehicle body through the subframe bushing corresponding to the second connecting part by the same fastening assembly. This allows the subframe bushing and the powertrain bracket to share the same fastening assembly, thereby reducing the number of parts and thus lowering production costs.

[0019] Secondly, the subframe is integrally cast from aluminum alloy, which not only facilitates processing and forming and provides high structural strength, but also allows for a lightweight design of the subframe assembly. Subframe bushings at both ends of the second beam allow the subframe to be mounted on the vehicle body via four bushings, resulting in good installation stability. The main body and two inclined sections on the second beam enhance the load-bearing and transmission of external forces. The sleeves on the main body facilitate cooperation with the first connection to improve the installation effect of the powertrain on the subframe. Placing the subframe bushings at the ends of the inclined sections allows for the timely dispersion and transmission of any external forces received.

[0020] Furthermore, by setting two opposing sub-supports, with the second connecting part of the sub-supports corresponding to the subframe bushing of the other inclined section, not only can two subframe bushings be shared, but the sub-supports, subframe, and body can also be effectively connected together using the same fastening assembly. This helps reduce redundant connection structures and improves the installation stability of the powertrain. By setting four sub-supports at each end of the second beam, with the second connecting part of the sub-supports corresponding to the subframe bushing, four subframe bushings and corresponding fastening assemblies can be shared, further reducing the number of parts.

[0022] Furthermore, the vertical plate of the second part is connected to the first part, and the second connecting hole is located on the horizontal plate, which facilitates processing and shaping and provides a better connection effect. The vertical plate and the connecting block on the vertical plate are detachably connected, facilitating disassembly and reducing replacement and maintenance costs.

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Example 1

[0045] This embodiment relates to a subframe assembly that, by optimizing its own structure, solves the problems of the large number of parts and high production costs caused by the separate design and arrangement of the suspension bushing 3 and the subframe bushing 4 in the prior art.

[0046] In terms of overall structure, the subframe assembly described in this embodiment includes a subframe 1 and a powertrain bracket mounted on the subframe 1. The subframe 1 includes a first beam 101 arranged opposite to each other in a first direction, a second beam 102 arranged opposite to each other in a second direction, and a plurality of subframe bushings 4 for mounting the subframe 1 onto the vehicle body.

[0047] The powertrain bracket is provided with a first connecting part and a second connecting part. The first connecting part is used to connect the powertrain 5 and the subframe 1 together. The second connecting part is provided corresponding to at least part of the subframe bushing 4. The second connecting part and the corresponding subframe bushing 4 are connected to the subframe 1 and the powertrain bracket to the vehicle body by the same fastening assembly.

[0048] The subframe assembly described in this embodiment connects the powertrain 5 and the subframe 1 together through the first connecting part on the powertrain bracket, which facilitates the installation of the powertrain 5 on the subframe 1. The subframe 1 and the powertrain bracket are connected to the vehicle body through the subframe bushing 4 corresponding to the second connecting part by the same fastening assembly. This allows the powertrain bracket and the subframe 1 to share the subframe bushing 4 and the fastening assembly, thereby reducing the number of parts and thus reducing production costs.

[0049] Based on the above overview, an exemplary structure of the subframe assembly described in this embodiment is as follows: Figure 1 and Figure 2 As shown in the diagram, the subframe 1 is generally U-shaped, which is not only simple in structure and easy to implement, but also has good structural strength and stability. The powertrain bracket can be set at the top or bottom of the subframe 1 for mounting the powertrain 5, which can be a drive motor, etc. In this embodiment, the first direction can be the front-rear direction or the left-right direction of the vehicle, and the second direction is set perpendicular to the first direction. The following description uses the example of the first direction being the front-rear direction of the vehicle, the second direction being the left-right direction of the vehicle, the third direction being the height direction of the vehicle, and the powertrain bracket being set at the bottom of the subframe 1 to illustrate the structure of the subframe assembly.

[0050] like Figure 3 As shown, each of the second beams 102 has a mounting sleeve 104 at both ends for mounting the subframe bushing 4. One end of the mounting sleeve 104 is open, and the other end has a mounting hole through which the fastening assembly passes. The open end of the mounting sleeve 104 facilitates the installation of the subframe bushing 4. In a preferred embodiment, each of the second beams 102 has a subframe bushing 4 at both ends, and the four subframe bushings 4 are located at the four corners of the subframe 1. That is, a mounting sleeve 104 is provided at each of the four corners of the subframe 1, and the subframe bushing 4 is mounted on the vehicle body through the four subframe bushings 4, which helps to ensure the installation stability of the subframe 1.

[0051] Reference Figure 3 As shown, the second beam 102 in this embodiment includes a main body segment 1021 extending along a first direction, and inclined segments 1022 disposed at both ends of the main body segment 1021. A sleeve 103 arranged along a second direction is provided on the main body segment 1021. The sleeve 103 is used to install the suspension bushing 3, which is used to connect to the powertrain 5. The subframe bushing 4 is disposed at the end of the inclined segment 1022.

[0052] Here, the arrangement of the main body 1021 and two inclined sections 1022 on the second beam 102 is beneficial for improving the load-bearing and transmission effect of external forces. By placing the sleeve 103 on the main body 1021, it is beneficial to cooperate with the first connecting part to improve the installation effect of the powertrain 5 on the subframe 1. Placing the subframe bushing 4 at the end of the inclined section 1022 is beneficial for timely dispersion and transmission of force through the inclined section 1022. In specific implementation, the outer peripheral wall of the mounting cylinder 104 is connected to the end face of each inclined section 1022. The mounting cylinder 104 and the sleeve 103 are preferably integrally formed with the second beam 102, which is beneficial for further improving the structural integration of the subframe 1 and improving installation efficiency.

[0053] In a preferred embodiment, the powertrain bracket in this example includes two opposing sub-brackets 2. A sleeve 103 is positioned near one inclined section 1022, and the second connecting portion of each sub-bracket 2 corresponds to a subframe bushing 4 positioned near the other inclined section 1022. Figure 2 As shown, the two sleeves 103 are positioned close to the front inclined section 1022, and the second connecting parts of the two sub-supports 2 are correspondingly positioned with the subframe bushing 4 of the rear inclined section 1022. This arrangement not only allows for the sharing of two subframe bushings 4, but also enables the sub-supports 2, subframe 1, and vehicle body to be effectively connected together using the same fastening assembly, which helps reduce redundant connection structures and improves the installation stability of the powertrain 5.

[0054] In terms of specific structure, the sub-bracket 2 in this embodiment includes a first part 201 and a second part 202 connected to each other. The first part 201 is located inside the subframe 1, and the second part 202 is located below the subframe 1. The first connecting part includes a first connecting hole 2014 provided on the first part 201 along a first direction, and the second connecting part includes a shaft hole corresponding to the subframe bushing 4 and a second connecting hole 2024 provided on the second part 202.

[0055] In this embodiment, the first part 201 is disposed on the inner side of the subframe 1, which facilitates the connection between the powertrain 5 and the subframe 1 bracket. The second part 202 is disposed below the subframe 1, which facilitates its placement corresponding to the subframe bushing 4, allowing the subframe bushing 4 to be shared. The structure of the first connecting hole 2014 is simple and easy to arrange. The second connecting hole 2024 is disposed corresponding to the shaft hole of the subframe bushing 4, which facilitates the sharing of the same fastening component and the subframe bushing 4.

[0056] Reference Figure 5 and Figure 6As shown, the first part 201 of this embodiment includes a vertical plate 2011 extending along a first direction and a horizontal plate 2012 extending along a second direction. A first connecting hole 2014 is provided on the horizontal plate 2012. The vertical plate 2011 is connected to the second part 202, and a third connecting part for connecting to the powertrain 5 is provided on the vertical plate 2011. Due to the arrangement of the vertical plate 2011 and the horizontal plate 2012, the first part 201 is generally L-shaped, which not only has a simple structure and is easy to process and form, but also has good structural stability. At the same time, the L-shaped first part 201 also helps to strengthen its own strength, thereby improving the force transmission effect.

[0057] like Figure 1 As shown, the first part 201 is spaced apart from both the powertrain 5 and the subframe 1, and the powertrain 5 and the subframe 1 are spaced apart in a third-order upward direction. To facilitate the connection between the powertrain 5, the first part 201, and the subframe 1, as shown... Figure 3 As shown, a downwardly protruding protrusion 105 is provided on the first beam 101 located at the rear, and the protrusion 105 is provided in a one-to-one correspondence with the horizontal plate 2012. A first protruding post 501 is provided on the power assembly 5, which protrudes into the horizontal plate 2012, and a second protruding post 2013 is provided on the horizontal plate 2012, which protrudes into the corresponding protrusion 105. The first connecting hole 2014 passes through the second protruding post 2013.

[0058] The protrusion 105 has a third connecting hole 1051 corresponding to the first connecting hole 2014, and the first protrusion 501 has a fourth connecting hole corresponding to the first connecting hole 2014. Connecting components, such as bolts, can sequentially pass through the third connecting hole 1051, the first connecting hole 2014, and the fourth connecting hole in a first direction and be screwed together. In the connected state, the second protrusion 2013 and the cross plate 2012 are sandwiched between the first protrusion 501 and the protrusion 105, thereby connecting the rear end of the powertrain 5 to the first beam 101.

[0059] To improve the connection between the vertical plate 2011 and the powertrain 5, the third connection portion includes a plurality of fifth connection holes 2016 disposed at the free end of the vertical plate 2011. As one possible implementation, such as... Figure 6 As shown, there are two fifth connecting holes 2016 spaced apart along a third direction. Corresponding to the fifth connecting holes 2016, a third protruding post 502 protruding towards the vertical plate 2011 is provided on the side wall of the powertrain 5, and a sixth connecting hole is provided within the third protruding post 502. Bolts pass through the fifth connecting holes 2016 and are screwed into the sixth connecting holes, thus achieving the connection between the powertrain 5 and the vertical plate 2011. Of course, in specific implementations, the number and position of the fifth connecting holes 2016 can be adaptively adjusted according to usage requirements.

[0060] As a preferred implementation method, such as Figure 5 and Figure 7 As shown, the second part 202 includes a vertical plate 2021 extending along a first direction and a horizontal plate 2022 extending along a second direction. The vertical plate 2021 is connected to the first part 201, and a second connecting hole 2024 is provided on the horizontal plate 2022. The arrangement of the vertical plate 2021 and the horizontal plate 2022 makes the second part 202 also "L"-shaped, which not only facilitates processing and forming but also provides a better connection effect. In addition, the "L"-shaped second part 202 also helps to strengthen the strength of the corner of the subframe 1, thereby improving the force transmission effect at the corner of the subframe 1.

[0061] Considering that the second connecting hole 2024 on the transverse plate 2022 is connected to the shaft hole of the subframe bushing 4, in the specific arrangement, the transverse plate 2022 abuts against the bottom end of the inner tube in the middle of the subframe bushing 4, so that the entire second part 202 and the subframe 1 are spaced apart in the third direction. The fastening assembly includes bolts that pass sequentially through the second connecting hole 2024, the shaft hole of the subframe bushing 4, and the vehicle body in the third direction, as well as nuts that are screwed to the bolts. Here, the fastening assembly has a simple structure, is easy to arrange and implement, and is also convenient for disassembly and maintenance.

[0062] To connect the vertical plate 2011 and the vertical plate 2021 together, in this embodiment, as follows: Figures 5 to 7 As shown, the vertical plate 2011 has an outwardly protruding connecting post 2015, and the vertical plate 2021 has a downwardly protruding connecting block 2023. The connecting post 2015 and the connecting block 2023 are detachably connected. The arrangement of the connecting post 2015 and the connecting block 2023 facilitates the connection between the vertical plate 2011 and the vertical plate 2021. The detachable connection between the connecting post 2015 on the vertical plate 2011 and the connecting block 2023 on the vertical plate 2021 makes it easy to disassemble both, thereby reducing replacement and maintenance costs.

[0063] In specific implementation, a seventh connecting hole 2025 is provided on the connecting block 2023, and an eighth connecting hole 2017 is provided on the connecting column 2015. After the bolt passes through the seventh connecting hole 2025, it is screwed into the eighth connecting hole 2017 until the connecting column 2015 abuts against the connecting block 2023, indicating that the two are connected in place.

[0064] In this embodiment, the subframe 1 is integrally cast from aluminum alloy, which not only facilitates processing and forming and provides high structural strength, but also allows for a lightweight design of the subframe assembly. Furthermore, the first part 201 and the second part 202 can also be integrally cast from aluminum alloy or from ductile iron, which also helps ensure the strength and performance of the sub-support 2. Additionally, the sleeve 103 and mounting cylinder 104 are integrally formed with the first beam 101 and the second beam 102 to further improve installation efficiency.

[0065] like Figure 4 As shown in the figure, in this embodiment, the two suspension bushings 3 and the two subframe bushings 4 shared by the second part 202 and the subframe 1 are connected in a trapezoidal shape. Figure 4 As shown by the dashed line, the center of gravity of the powertrain 5 is located within the area defined by the trapezoidal profile. Two suspension bushings 3 and two subframe bushings 4 are respectively positioned at the four corners of the trapezoid. This arrangement enhances the support effect of the subframe 1 on the powertrain 5, providing high support stability and reducing deformation, thereby effectively suppressing the displacement and rotation of the powertrain 5's center of gravity and thus reducing vibration transmission. Furthermore, in this subframe assembly structure, the first beam 101 can effectively collapse and absorb energy during a head-on collision, further improving the vehicle's collision safety.

[0066] In this embodiment, the subframe assembly optimizes the structure of the powertrain 5 so that one end of the powertrain 5 is connected to the suspension bushing 3 on the second beam 102 in the second direction, and the other end of the powertrain 5 is directly connected to the first beam 101 in the first direction through the horizontal plate 2012 on the first part 201. Furthermore, through the vertical plate 2021 on the second part 202, the other end of the powertrain 5 is also connected to the subframe bushing 4 in the second direction via the second part 202. This not only helps to ensure the installation stability of the powertrain 5 on the subframe 1, but also helps to ensure the force transmission and vibration reduction effects.

[0067] Furthermore, the subframe 1 can also provide a reaction force to the output torque of the powertrain 5, resulting in better torsional limiting and thus ensuring the stability of the powertrain 5. Moreover, it allows the suspension bushing 3 and the subframe bushing 4 to have the same specifications, further reducing the variety of parts, lowering production costs, and improving platform efficiency. Of course, depending on the application requirements, the suspension bushing 3 and the subframe bushing 4 can also be configured with different specifications.

[0068] Example 2

[0069] This embodiment relates to a subframe assembly, which has a substantially the same structure as the subframe assembly in Embodiment 1, the only difference being the structural form of the powertrain bracket.

[0070] like Figure 8 As shown, the powertrain bracket in this embodiment includes four sub-braces 2 located at each end of the second beam 102. The second connecting portion of each sub-braces 2 is correspondingly arranged with the subframe bushing 4 at the corresponding end of the second beam 102. This arrangement allows the sub-braces 2 to share four subframe bushings 4 and four fastening components, further reducing the number of parts.

[0071] In practical implementation, the four sub-supports 2 have identical structures, and all are the same as the structure of the sub-support 2 in Embodiment 1. Therefore, the structure and connection method of the sub-supports 2 will not be described in detail here. The four sub-supports 2 are symmetrically arranged in both the first and second directions. This facilitates the improvement of the installation stability of the powertrain 5 on the subframe 1, reduces the types of parts, lowers production costs, and improves platform efficiency. Simultaneously, the two first beams 101 and the two second beams 102 are also symmetrically arranged to further enhance the structural strength and stability of the subframe 1.

[0072] In this embodiment, the subframe assembly is configured with four sub-supports 2. In the first direction, the front and rear ends of the powertrain 5 are connected to the first beam 101 via horizontal plates 2012. In the second direction, the sides of both ends of the powertrain 5 are first connected to the vertical plate 2021 via vertical plates 2011, and then connected to the shaft holes of the subframe bushing 4 via horizontal plates 2022. This eliminates the need for the sleeve 103 and the suspension bushing 3 installed within the sleeve 103 in Embodiment 1. The powertrain 5 is specifically connected to the subframe bushing 4 via the first part 201 and the second part 202, and is fixed to the vehicle body along with the subframe 1 via fastening components. This reduces the number of parts and improves installation efficiency.

[0073] Example 3

[0074] This embodiment relates to a vehicle that has a subframe assembly as described in the previous embodiment.

[0075] The vehicle described in this embodiment, by setting up the subframe assembly as described above, helps to reduce the number of parts, thereby helping to reduce production costs.

[0076] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
