It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0028] To address the technical problems of low platform standardization, high component development costs, and complex assembly processes in existing subframes, one embodiment of this application provides a front subframe assembly. This front subframe assembly includes a first subframe body and a second subframe body; the first subframe body is provided with a first suspension assembly, a beam mounting portion, and a suspension mounting portion; the beam mounting portion is equipped with a first conversion beam, and the first conversion beam is equipped with a second suspension assembly, which is used to cooperate in mounting a motor; or, the suspension mounting portion is equipped with a third suspension assembly, which is used to cooperate in mounting a motor; the second subframe body is connected to the first subframe body, and the second subframe body is equipped with a fourth suspension assembly, which is used to mount the engine. This will be described in detail below.

[0029] In one embodiment, the vehicle includes a subframe assembly. The subframe assembly is either a front subframe assembly or a rear subframe assembly. The front subframe assembly is located at the front of the vehicle and connects the front suspension system and the body structure. The rear subframe assembly is located at the rear of the vehicle and connects the rear suspension system and the body structure. The front and rear subframe assemblies respectively support and stabilize the front and rear of the vehicle.

[0030] The front subframe assembly of this application is described below.

[0031] Please see Figure 1 and Figure 2 , Figure 1 This is a structural diagram of the front subframe assembly in its first state according to this application. Figure 2 This is a structural schematic diagram of the front subframe assembly in the second state of this application.

[0032] In one embodiment, the front subframe assembly 10a includes a first subframe body 11, on which a first suspension assembly 21, a beam mounting portion 114, and a suspension mounting portion 115 are disposed. The beam mounting portion 114 is fitted with a first transfer beam 121, and a second suspension assembly 22 is disposed on the first transfer beam 121. The first suspension assembly 21 and the second suspension assembly 22 are used to cooperate in mounting a motor; or, the suspension mounting portion 115 is fitted with a third suspension assembly 23, and the first suspension assembly 21 and the third suspension assembly 23 are used to cooperate in mounting a motor.

[0033] In other words, the front subframe assembly 10a in this embodiment has a first state and a second state. In the first state, the beam mounting portion 114 mounts a first conversion beam 121, and a second suspension assembly 22 is disposed on the first conversion beam 121. The first suspension assembly 21 and the second suspension assembly 22 are used to cooperate in mounting the motor. In the second state, the suspension mounting portion 115 mounts a third suspension assembly 23, and the first suspension assembly 21 and the third suspension assembly 23 are used to cooperate in mounting the motor. The front subframe assembly 10a ultimately presents either the first state or the second state; that is, the first state and the second state will not coexist simultaneously in the front subframe assembly 10a.

[0034] Through the above methods, the front subframe assembly 10a of this embodiment can be compatible with different arrangements of the motor (powertrain). It can achieve different powertrain arrangements without replacing the first subframe body 11, meeting the platform's commonality requirements. Furthermore, by not replacing the first subframe body 11, this embodiment avoids the increased component development costs and complex assembly processes caused by changes to the subframe body in existing technologies. Therefore, this embodiment can save component development costs and simplify the assembly process.

[0035] It should be noted that the first subframe body 11 in this embodiment can be an integrated cast aluminum structure, etc. The first subframe body 11 effectively reduces the assembly process of parts, and uses the same subframe body to achieve matching of different powertrains with minimal structural changes, thereby maximizing the platform commonality rate and reducing vehicle development costs.

[0036] Please also refer to Figure 3 and Figure 4 , Figure 3 This is a structural schematic diagram of an embodiment of the subframe body of the front subframe assembly of this application. Figure 4 yes Figure 3 The diagram shows a cross-sectional view of the subframe body in the GG direction of the front subframe assembly.

[0037] In one embodiment, the front subframe assembly 10a has a first direction X and a second direction Y that are perpendicular to each other. The first subframe body 11 includes a first frame beam 111, a second frame beam 112, and a third frame beam 113. A first suspension assembly 21 is disposed on the first frame beam 111. The second frame beam 112 is connected to one end of the first frame beam 111 in the first direction X, and the second frame beam 112 is located on one side of the first frame beam 111 in the second direction Y. The third frame beam 113 is connected to the other end of the first frame beam 111 in the first direction X, and the second frame beam 112 and the third frame beam 113 are located on the same side of the first frame beam 111 in the second direction Y. The ends of the second frame beam 112 and the third frame beam 113 away from the first frame beam 111 form beam mounting portions 114 in the first direction X. Specifically, the gap between the ends of the second frame beam 112 and the third frame beam 113 away from the first frame beam 111 in the first direction X is the beam mounting portion 114. The second frame beam 112 and / or the third frame beam 113 are provided with suspension mounting portions 115.

[0038] It should be noted that, in this embodiment, both the second frame beam 112 and the third frame beam 113 may be provided with suspension mounting portions 115. The form of the suspension mounting portion 115 can be reasonably designed according to the fixing method of the third suspension assembly 23. Figure 4 Taking the suspension mounting portion 115 on the second frame beam 112 as an example, the third suspension assembly 23 is fastened to the second frame beam 112 by bolts or other fasteners, and the suspension mounting portion 115 corresponds to the bolt holes. It can be understood that if the third suspension assembly 23 is installed on the second frame beam 112 by welding, then the suspension mounting portion 115 can correspond to the area on the second frame beam 112 used for welding the third suspension assembly 23, which is not limited here. The suspension mounting portion 115 on the third frame beam 113 is similar.

[0039] In one embodiment, the first state of the front subframe assembly 10a corresponds to a single motor arrangement. Specifically, there are at least two first suspension components 21, which are spaced apart along a first direction X. When the beam mounting portion 114 is equipped with a first conversion beam 121, the second suspension component 22 is located between two adjacent first suspension components 21 in the first direction X, and each first suspension component 21 and the second suspension component 22 are used to cooperate in mounting the same motor.

[0040] For example, there are two first suspension components 21, which are respectively disposed at both ends of the first frame beam 111 in the first direction X. The first transfer beam 121 is disposed between the end of the second frame beam 112 away from the first frame beam 111 and the end of the third frame beam 113 away from the first frame beam 111. A second suspension component 22 is disposed on the first transfer beam 121, which is located between the two first suspension components 21 in the first direction X. Each first suspension component 21 and the second suspension component 22 cooperate to install the same motor, so that the motor is arranged in a three-point centroid arrangement.

[0041] like Figure 5 As shown, the second suspension assembly 22 includes a second suspension bracket 221 and a second suspension bushing 222. The second suspension bracket 221 can be fastened to the first conversion beam 121 by bolts or other fasteners. The second suspension bracket 221 is provided with the second suspension bushing 222, which is used to connect to the motor, thereby enabling the motor to be mounted on the front subframe assembly 10a. The connection method between the second suspension bushing 222 and the motor is within the understanding of those skilled in the art and will not be described in detail here.

[0042] In one embodiment, the second state of the front subframe assembly 10a corresponds to a dual-motor arrangement. Specifically, there are at least two first suspension components 21, each spaced apart along a first direction X. The second frame beam 112 and the third frame beam 113 are each provided with a suspension mounting portion 115. The third suspension component 23 on the second frame beam 112 is mounted on the suspension mounting portion 115, and the third suspension component 23 on the second frame beam 112 is used to cooperate with the adjacent first suspension component 21 to mount the same motor. The third suspension component 23 on the third frame beam 113 is also mounted on the suspension mounting portion 115, and the third suspension component 23 on the third frame beam 113 is used to cooperate with the adjacent first suspension component 21 to mount the same motor. The third suspension components 23 on the second frame beam 112 and the third suspension components 23 on the third frame beam 113 are used to mount different motors, realizing a four-point suspension arrangement for dual motors.

[0043] For example, there are two first suspension components 21, which are respectively disposed at both ends of the first frame beam 111 in the first direction X. Figure 6 As shown, the first suspension assembly 21 includes a first mounting bracket 211, a first suspension support 212, and a first suspension bushing 213. The first mounting bracket 211 is welded to the first frame beam 111. The first suspension support 212 can be fastened to the first frame beam 111 by bolts or other fasteners. The first suspension support 212 is provided with the first suspension bushing 213, which is used to connect with the motor, thereby mounting the motor to the front subframe assembly 10a. The connection method between the first suspension bushing 213 and the motor is within the understanding of those skilled in the art and will not be described in detail here.

[0044] The first suspension assembly 21 near the second frame beam 112 and the third suspension assembly 23 on the second frame beam 112 are used to mount the same motor. Similarly, the first suspension assembly 21 near the third frame beam 113 and the third suspension assembly 23 on the third frame beam 113 are used to mount the same motor, and the third suspension assembly 23 on the second frame beam 112 and the third suspension assembly 23 on the third frame beam 113 are used to mount different motors. Figure 7 As shown, the third suspension assembly 23 includes a third suspension support 231 and a first mounting bushing 232. The third suspension support 231 can be fastened to the second frame beam 112 or the third frame beam 113 by fasteners such as bolts (not shown). The third suspension support 231 is used to connect to the motor. The first mounting bushing 232 is sleeved on the outer periphery of the fastener and is located between the fastener and the third suspension support 231.

[0045] In one embodiment, the front subframe assembly 10a further includes a second transfer beam 122, with the first transfer beam 121 and the second transfer beam 122 selectively mounted on the beam mounting portion 114. In other words, when the front subframe assembly 10a is in a first state, the first transfer beam 121 is mounted on the beam mounting portion 114, and the second transfer beam 122 is not mounted on the beam mounting portion 114; while when the front subframe assembly 10a is in a second state, the second transfer beam 122 is mounted on the beam mounting portion 114, and the first transfer beam 121 is not mounted on the beam mounting portion 114.

[0046] The second conversion beam 122 does not have a second suspension assembly 22. Based on the fact that the ends of the second frame beam 112 and the third frame beam 113 away from the first frame beam 111 form beam mounting portions 114 in the first direction X, in this embodiment, the second conversion beam 122 is connected to the ends of the second frame beam 112 and the third frame beam 113 away from the first frame beam 111, respectively. The second conversion beam 122 replaces the first conversion beam 121 and is installed in the beam mounting portion 114. The second conversion beam 122 connects the second frame beam 112 and the third frame beam 113, making the overall structure of the first subframe body 11 relatively complete. This avoids the beam mounting portion 114 between the second frame beam 112 and the third frame beam 113 affecting the overall structural strength of the first subframe body 11 after the first conversion beam 121 is removed.

[0047] In one embodiment, the second frame beam 112 includes a first connecting beam portion 1121 and a first extending beam portion 1122. The first connecting beam portion 1121 is connected to one end of the first frame beam 111 in the first direction X, and is located on one side of the first frame beam 111 in the second direction Y. The first extending beam portion 1122 is connected to the end of the first connecting beam portion 1121 in the second direction Y away from the first frame beam 111, and is located on the side of the first connecting beam portion 1121 in the first direction X closer to the third frame beam 113. The first extending beam portion 1122 and the third frame beam 113 form a beam mounting portion 114 in the first direction X. Specifically, the first extending beam portion 1122 and the third frame beam 113 may be spaced apart from each other in the first direction X, and the gap between the first extending beam portion 1122 and the third frame beam 113 in the first direction X is the beam mounting portion 114.

[0048] In the above manner, the second frame beam 112 is provided with a first extension beam portion 1122 extending along the first direction X, which can reduce the size of the beam mounting portion 114 in the first direction X, thereby reducing the impact of the design of the default beam structure of the beam mounting portion 114 on the overall structural strength of the first subframe body 11, that is, it is beneficial to ensure the overall structural strength of the first subframe body 11.

[0049] Furthermore, the suspension mounting portion 115 of the second frame beam 112 is provided on the first connecting beam portion 1121 so that after the third suspension assembly 23 is installed on the suspension mounting portion 115 on the second frame beam 112, the third suspension assembly 23 on the second frame beam 112 can cooperate with the adjacent first suspension assembly 21 to install the motor.

[0050] In one embodiment, the third frame beam 113 includes a second connecting beam portion 1131 and a second extending beam portion 1132. The second connecting beam portion 1131 is connected to the other end of the first frame beam 111 in the first direction X, and the second connecting beam portion 1131 and the second frame beam 112 are located on the same side of the first frame beam 111 in the second direction Y. The second extending beam portion 1132 is connected to the end of the second connecting beam portion 1131 away from the first frame beam 111 in the second direction Y, and the second extending beam portion 1132 is located on the side of the second connecting beam portion 1131 close to the second frame beam 112 in the first direction X. The second extending beam portion 1132 and the second frame beam 112 form a beam mounting portion 114 in the first direction X. Specifically, the second extending beam portion 1132 and the second frame beam 112 may be spaced apart from each other in the first direction X, and the gap between the second extending beam portion 1132 and the second frame beam 112 in the first direction X is the beam mounting portion 114. In other words, in this embodiment of the application, the end of the second extended beam portion 1132 away from the second connecting beam portion 1131 and the end of the first extended beam portion 1122 away from the first connecting beam portion 1121 are spaced apart from each other in the first direction X to form a beam mounting portion 114.

[0051] In the above manner, the third frame beam 113 is provided with a second extension beam portion 1132 extending along the first direction X, which can reduce the size of the beam mounting portion 114 in the first direction X, thereby reducing the impact of the design of the default beam structure of the beam mounting portion 114 on the overall structural strength of the first subframe body 11, that is, it is beneficial to ensure the overall structural strength of the first subframe body 11.

[0052] Furthermore, the suspension mounting portion 115 of the third frame beam 113 is provided on the second connecting beam portion 1131 so that after the third suspension assembly 23 is installed on the suspension mounting portion 115 on the third frame beam 113, it is convenient for the third suspension assembly 23 on the third frame beam 113 to cooperate with the adjacent first suspension assembly 21 to install the motor.

[0053] In one embodiment, the front subframe assembly 10a further includes a second subframe body 14, which is connected to the first subframe body 11. A fourth suspension assembly 24 is provided on the second subframe body 14 for mounting the engine.

[0054] Specifically, in the second direction Y, the second subframe body 14 is connected to the second frame beam 112 and the side of the third frame beam 113 away from the first frame beam 111. For hybrid and range-extended vehicles, the powertrain often includes an engine, which is usually located in the front subframe assembly 10a. In view of this, in this embodiment, the front subframe assembly 10a is provided with a second subframe body 14, and a fourth mounting assembly 24 for mounting the engine is provided on the second subframe body 14 to be compatible with the engine layout of hybrid and range-extended vehicles, further compatible with the layout of different powertrains, and meet the platform commonality requirements.

[0055] It should be noted that in this embodiment, the first subframe body 11 and the second subframe body 14 can be an integrated cast aluminum structure, etc. The integrated design of the first subframe body 11 and the second subframe body 14 effectively reduces the assembly process of parts. By using the same subframe body, different powertrains can be matched with minimal structural changes, maximizing the platform commonality rate and reducing vehicle development costs.

[0056] Of course, for pure electric vehicles, since the powertrain does not include an engine, the second subframe body 14 can be omitted from the front subframe assembly 10a to further simplify the structure of the front subframe assembly 10a, save on parts development costs, and simplify the assembly process. Alternatively, for pure electric vehicles, the second subframe body 14 can also be retained, so that the front subframe assembly 10a in this embodiment can be compatible with the design of more models such as hybrid, range-extended, and pure electric vehicles, improve the platform commonality rate, and reduce vehicle development costs.

[0057] In summary, this application provides a front subframe assembly and a vehicle. The front subframe assembly has a first transfer beam mounted on a beam mounting portion on its first subframe body. A second suspension assembly is disposed on the first transfer beam, and the first and second suspension assemblies are used to cooperate in mounting a motor. Alternatively, a third suspension assembly is mounted on a suspension mounting portion on the first subframe body, and the first and third suspension assemblies are used to cooperate in mounting a motor.

[0058] In other words, the front subframe assembly of this application is compatible with different arrangements of the motor (powertrain), and can achieve different powertrain arrangements without replacing the first subframe body, thus meeting the platform commonality requirements. Furthermore, by not replacing the first subframe body, this application avoids the increased component development costs and complex assembly processes caused by changes to the subframe body in existing technologies. Therefore, this application can save component development costs and simplify the assembly process.

[0059] The foregoing has provided a detailed description of the front subframe assembly and vehicle provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
