[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0037] According to the first aspect of this application, see Figures 1 to 6 This application provides a vehicle frame.

[0038] See Figure 1 and Figure 2 The frame includes a longitudinal beam 1, a cross beam 2 and a connecting beam 3. The connecting beam 3 connects the longitudinal beam 1 and the cross beam 2. At least one of the longitudinal beam 1 and the connecting beam 3 is provided with a connecting structure 4. The connecting structure 4 is used for detachable connection with at least one of the leaf spring suspension 5 and the airbag suspension 7.

[0039] Understandably, the connecting structure 4 at the frame is detachably connected to at least one of the leaf spring suspension 5 and the airbag suspension 7, allowing at least one of the leaf spring suspension 5 and the airbag suspension 7 to be detachably connected to the frame. In other words, when the frame and leaf spring suspension 5 need to be compatible, they can be connected using the connecting structure 4. When the frame needs to be compatible with other suspension systems (such as airbag suspension), the leaf spring suspension 5 can be detached from the frame to allow other suspension systems to be installed on the frame. This allows the frame to be compatible with multiple suspension systems, improving its adaptability.

[0040] Understandably, in related technologies, because the leaf spring suspension 5 is fixedly connected to the frame, it is difficult to remove the leaf spring suspension 5 from the frame after it is installed. Consequently, the obstruction caused by the leaf spring suspension 5 also makes it difficult to install other suspension systems onto the bracket, resulting in insufficient frame compatibility. This application, however, uses a detachable connection structure 4 between the leaf spring suspension 5 and the frame, allowing the leaf spring suspension 5 to be both installed on and removed from the frame without affecting the installation of other suspension systems, thus improving frame compatibility.

[0041] In some examples, see Figure 3 When the frame needs to be adapted to the front independent suspension system 6, the leaf spring suspension 5 is removed from the connecting structure 4, and then the front independent suspension system 6 is installed on the frame.

[0042] In some examples, when the vehicle frame needs to be adapted to the front airbag suspension system, the leaf spring suspension 5 is removed from the connecting structure 4, and then the front airbag suspension system is installed onto the vehicle frame. For example, the front airbag suspension system can be connected to the connecting structure 4 to achieve installation.

[0043] In some examples, the mounting base 51 of the leaf spring suspension 5 and the connecting structure 4 are, for example, assembled casting structures. Exemplarily, the casting structure can be designed with bolt mounting holes to allow for segmented assembly and disassembly of the components.

[0044] In some examples, the connection structure 4 is, for example, a connection hole or a connection plate.

[0045] Understandably, the connecting structure 4 can be used to connect the leaf spring suspension 5, achieving compatibility between the vehicle frame and the leaf spring suspension 5 suspension system. Alternatively, the leaf spring suspension 5 can be removed from the connecting structure 4, and the airbag suspension 7 can be connected to the connecting structure 4, achieving compatibility between the vehicle frame and the airbag suspension 7.

[0046] In some embodiments, see Figure 1 and Figure 2 The connecting structure 4 includes a first connecting structure 41 and a second connecting structure 42. The first connecting structure 41 is formed on the longitudinal beam 1, and the second connecting structure 42 is formed on the connecting beam 3. Both the first connecting structure 41 and the second connecting structure 42 are used for detachable connection with the leaf spring suspension 5.

[0047] Understandably, the leaf spring suspension 5 can be connected to both the first connecting structure 41 and the second connecting structure 42, which increases the connection points between the leaf spring suspension 5 and the vehicle frame, thus improving the installation stability of the leaf spring suspension 5.

[0048] In some embodiments, the first connecting structure 41 is located at the connection between the longitudinal beam 1 and the connecting beam 3; and / or,

[0049] The second connecting structure 42 is located at the connection between the connecting beam 3 and the longitudinal beam 1.

[0050] It is understandable that the structural strength of the connection between the longitudinal beam 1 and the connecting beam 3 is high. Designing the first connecting structure 41 at the connection between the longitudinal beam 1 and the connecting beam 3 is beneficial to ensuring the connection stability between the leaf spring suspension 5 and the vehicle.

[0051] It is understandable that the structural strength of the connection between the connecting beam 3 and the longitudinal beam 1 is high. Designing the second connecting structure 42 at the connection between the connecting beam 3 and the longitudinal beam 1 is beneficial to ensuring the connection stability between the leaf spring suspension 5 and the vehicle.

[0052] In some embodiments, the crossbeam 2 is, for example, a front crossbeam, and the connecting beam 3 is, for example, a front connecting beam.

[0053] In some embodiments, the frame also includes a connecting seat for connecting the leaf spring suspension 5 and the connecting structure 4.

[0054] Specifically, the connector and the connecting structure 4 are detachably connected.

[0055] It is understandable that the leaf spring suspension 5 is connected to the connecting seat, and the connecting seat is detachably connected to the connecting structure 4, thus realizing the detachable connection between the leaf spring suspension 5 and the connecting structure 4.

[0056] Specifically, the connecting seat and the connecting structure 4 are integrally formed, and the connecting seat is used for detachable connection with the leaf spring suspension 5.

[0057] It is understandable that the connecting seat can be integrally formed with the connecting structure 4, meaning the connecting seat is fixedly connected to the connecting structure 4, while the leaf spring suspension 5 is detachably connected to the connecting seat, thus achieving a detachable connection between the leaf spring suspension 5 and the connecting structure 4. This also allows the leaf spring suspension 5 to directly reuse the connecting seat, eliminating the need to separately manufacture the leaf spring suspension 5 support and avoiding the need for a separate casting mold design for the leaf spring suspension 5 support.

[0058] In some embodiments, see Figure 1 , Figure 5 and Figure 6 The longitudinal beam 1 includes a first longitudinal beam 11 and a second longitudinal beam 12 arranged opposite to each other, and the connecting beam 3 includes a first connecting beam 31 and a second connecting beam 32 arranged opposite to each other. The first connecting beam 31 connects the first longitudinal beam 11 and the first end of the crossbeam 2, and the second connecting beam 32 connects the second longitudinal beam 12 and the second end of the crossbeam 2.

[0059] Along the length of the crossbeam 2, at least part of the distance between the first connecting beam 31 and the second connecting beam 32 is greater than the distance between the first longitudinal beam 11 and the second longitudinal beam 12.

[0060] It is understood that there is an installation space between the first connecting beam 31 and the second connecting beam 32, and a receiving space between the first longitudinal beam 11 and the second longitudinal beam 12. Along the length of the crossbeam 2, the length of the installation space is greater than the length of the receiving space, thereby increasing the volume of components that can be installed between the first connecting beam 31 and the second connecting beam 32.

[0061] It is understandable that a cooling module can be installed between the first connecting beam 31 and the second connecting beam 32. However, in related technologies, the distance between the first connecting beam 31 and the second connecting beam 32 is the same as the distance between the first longitudinal beam 11 and the second longitudinal beam 12, which limits the volume of the cooling module. In this application, the distance between the first connecting beam 31 and the second connecting beam 32 is designed to be greater than the distance between the first longitudinal beam 11 and the second longitudinal beam 12, thereby accommodating a larger cooling module. This allows for the expansion of the high-horsepower motor within the existing frame width. Moreover, this improvement method is simple and does not require the addition of other additional combination brackets. It not only reduces production costs but also has minimal impact on the chassis system components, maximizing the preservation of existing platform resources. There is no need to develop a new design platform to match high-horsepower vehicles, significantly reducing design costs and development time.

[0062] Understandably, adding other bracket combinations to accommodate larger components increases production costs and necessitates redesigning surrounding components to accommodate these bracket combinations, thus increasing design costs. This embodiment, however, reduces assembly errors. Furthermore, its highly integrated design facilitates lightweight chassis solutions, reduces costs and increases efficiency, and significantly reduces the number of load-bearing brackets that fail during road tests, thereby enhancing product competitiveness.

[0063] In some embodiments, see Figure 1 , Figure 5 and Figure 6 The first connecting beam 31 includes a first connecting beam body 311 and a first connecting portion 312. A first end of the first connecting portion 312 is connected to the first longitudinal beam 11, and a second end of the first connecting portion 312 is connected to the first connecting beam body 311. Along the length of the crossbeam 2, the second end of the first connecting portion 312 is bent or inclined in a direction away from the center of the frame; and / or,

[0064] The second connecting beam 32 includes a second connecting beam body 321 and a second connecting part 322. The first end of the second connecting part 322 is connected to the second longitudinal beam 12, and the second end of the second connecting part 322 is connected to the second connecting beam body 321. Along the length direction of the crossbeam 2, the second end of the second connecting part 322 is bent or tilted in a direction away from the center of the frame.

[0065] It is understandable that bending or tilting the second end of the first connecting part 312 away from the center of the frame can increase the distance between the first connecting beam body 311 and the first longitudinal beam 11 (the distance along the transverse length direction, which can also be understood as the distance in the width direction of the vehicle), thereby increasing at least part of the distance between the first connecting beam 31 and the second connecting beam 32, so that a larger volume component can be accommodated between the first connecting beam 31 and the second connecting beam 32.

[0066] It is understandable that bending or tilting the second end of the second connecting part 322 away from the center of the frame can increase the distance between the second connecting beam body 321 and the second longitudinal beam 12 (the distance along the transverse length direction, which can also be understood as the distance in the width direction of the vehicle), thereby increasing at least part of the distance between the second connecting beam 32 and the first connecting beam 31, so that a larger volume component can be accommodated between the first connecting beam 31 and the second connecting beam 32.

[0067] In some examples, the connecting beam 3 is a single casting, such as a single cast iron piece.

[0068] In some embodiments, see Figure 1 , Figure 5 and Figure 6 The first connecting part 312 includes a first connecting segment 3121 and a second connecting segment 3122. The first connecting segment 3121 connects the second connecting segment 3122 and the first connecting beam body 311. The second connecting part 322 includes a third connecting segment 3221 and a fourth connecting segment 3222. The third connecting segment 3221 connects the fourth connecting segment 3222 and the second connecting beam body 321.

[0069] Along the length of the crossbeam 2, the distance between the first connecting beam body 311 and the second connecting beam body 321 is greater than the distance between the second connecting segment 3122 and the fourth connecting segment 3222.

[0070] It is understandable that the second connecting segment 3122 is connected to the first longitudinal beam 11, and the fourth connecting segment 3222 is connected to the second longitudinal beam 12. The distance between the first connecting beam body 311 and the second connecting beam body 321 is greater than the distance between the second connecting segment 3122 and the fourth connecting segment 3222. That is, the first connecting beam body 311 protrudes from the first longitudinal beam 11, and the second connecting beam body 321 protrudes from the second longitudinal beam 12, so that a larger volume component can be accommodated between the first connecting beam body 311 and the second connecting beam body 321.

[0071] The first connecting segment 3121 is used to connect the first connecting segment 3121 and the first connecting beam body 311, that is, the first connecting segment 3121 can serve as a transition connection. The third connecting segment 3221 is used to connect the fourth connecting segment 3222 and the second connecting beam body 321, that is, the third connecting segment 3221 can serve as a transition connection.

[0072] In some examples, the first connecting segment 3121 and the third connecting segment 3221 are, for example, variable cross-section sections.

[0073] In some examples, in the width direction of the vehicle, the right side surface of the first connecting beam body 311 (which can be understood as the front part of the beam) is located to the left of the right side surface of the second connecting segment 3122 (which can be understood as the rear part of the beam), and the right side surface of the first connecting beam body 311 is located to the right or left of the left side surface of the second connecting segment 3122, or is flush with the left side surface of the rear part of the beam.

[0074] In the width direction of the vehicle, the left surface of the second connecting beam body 321 (which can be understood as the front part of the beam) is located to the right of the left surface of the fourth connecting section 3222 (which can be understood as the rear part of the beam), and the left surface of the second connecting beam body 321 is located to the left or right of the right surface of the fourth connecting section 3222, or is flush with the right surface of the rear part of the beam.

[0075] In some embodiments, along the length of the beam 2, the distance between the inner surface of the first connecting beam body 311 and the inner surface of the second connecting segment 3122 is not less than 60 mm; and / or,

[0076] Along the length of the crossbeam 2, the distance between the inner side of the second connecting beam body 321 and the inner side of the fourth connecting section 3222 is not less than 60mm.

[0077] Understandably, this allows the distance between the first connecting beam body 311 and the second connecting beam body 321 to reach 1000mm or more, enabling the installation of larger cooling modules to match 800-1000 horsepower motors and batteries.

[0078] In some embodiments, see Figure 1 , Figure 5 and Figure 6 The connecting beam 3 integrates at least one of the following: a first mounting structure 33 for connecting the bumper bracket, a second mounting structure 34 for connecting the vehicle body mount, a third mounting structure 35 for connecting the tow hook, a fourth mounting structure 36 for connecting the protective bracket, a fifth mounting structure 37 for connecting the steering gear bracket, and a wiring harness hole.

[0079] Understandably, this can improve the integration of connecting beam 3, simplify the connection method of surrounding components, and thus optimize the difficulty of installation and maintenance.

[0080] In some examples, the mounting structure may have multiple mounting holes and extend axially in the front-to-back direction.

[0081] In some examples, the first crossbeam 2 mounting structure includes four mounting holes and extends axially in the left-right direction. The third mounting structure 35 includes one mounting hole and extends axially in the front-back direction. The cooling module mounting structure includes two mounting holes and extends axially in the vertical direction. The first crossbeam 2 mounting structure and the third mounting structure 35 are located at the front of the connecting beam 3 body, with the third mounting structure 35 located on the front side of the first crossbeam 2 mounting structure, and the cooling module mounting structure located at the top of the connecting beam 3 body.

[0082] The first mounting structure 33 is a front bumper bracket mounting structure, which includes four mounting holes and extends axially in the left-right direction. The longitudinal beam 1 mounting structure includes two mounting holes and extends axially in the left-right direction. The front bumper bracket mounting structure and the longitudinal beam 1 mounting structure are located at the rear of the beam, and at least a portion of the front bumper bracket mounting structure is located on the underside of the longitudinal beam 1 mounting structure; for example, three mounting holes of the front bumper bracket mounting structure are located on the underside of the longitudinal beam 1 mounting structure. The wiring harness through-hole is located on the rear side of the front bumper bracket mounting structure.

[0083] The second mounting structure 34 is a front suspension mounting structure for the vehicle body, which includes four mounting holes. A portion of the front suspension mounting structure is located at the top of the front of the beam, and another portion is located at the top of the rear of the beam. For example, two mounting holes of the front suspension mounting structure are located at the top of the front of the beam and outside the cooling module mounting structure, while two mounting holes are located at the top of the rear of the beam and above the wiring harness through-hole. The axial direction of the two mounting holes of the front suspension mounting structure extends vertically, and the axial direction of the two mounting holes extends horizontally.

[0084] The fourth mounting structure 36 is, for example, a front lower protective bracket mounting structure. The front lower protective bracket mounting structure includes four mounting holes and extends axially in the left and right direction. A part of the front lower protective bracket mounting structure is located at the bottom of the front part of the beam and another part is located at the bottom of the variable cross section (first connecting section 3121 or third connecting section 3221). For example, three mounting holes of the front lower protective bracket mounting structure are located at the bottom of the front part of the beam and at the rear side of the first cross beam 2 mounting structure, and one mounting hole of the front lower protective bracket mounting structure is located at the bottom of the variable cross section.

[0085] The fifth mounting structure 37 includes six mounting holes and extends axially in the left-right direction. A portion of the steering gear bracket mounting structure is located at the front of the rear of the beam, and another portion is located at the variable cross-section section. For example, four mounting holes of the steering gear bracket mounting structure are located at the front of the rear of the beam, and two mounting holes of the steering gear bracket mounting structure are located at the variable cross-section section.

[0086] In some examples, the mounting structure can be integrally formed with the connecting beam 3 body. For instance, the front leaf spring suspension 5 mounting bracket structure can be designed as an integrated, one-piece solution for connecting and assembling the front leaf spring suspension 5, avoiding the need for casting mold design for the front leaf spring suspension 5 bracket. The steering gear mounting bracket can be designed as an integrated, one-piece solution for connecting and assembling the steering gear, avoiding the need for casting mold design for the steering gear mounting bracket. The front bumper beam mounting bracket can be designed as a sheet metal welded connection for assembling and connecting the front bumper beam, avoiding the need for molding design for the front bumper beam mounting bracket.

[0087] In some embodiments, the vehicle frame is provided with a first connecting bracket and a second connecting bracket, the first connecting bracket being used to connect an electro-hydraulic power steering system and the second connecting bracket being used to connect an electric power steering system.

[0088] Understandably, integrating the connecting brackets for the electro-hydraulic power steering system and the electric power steering system into the chassis improves the chassis's integration, allowing the chassis to accommodate both steering systems simultaneously. This helps optimize the front-end layout space of the vehicle and reduces unnecessary connection waste.

[0089] According to the second aspect of this application, see Figure 1 and Figure 2 This application provides a vehicle frame assembly, including at least one of a leaf spring suspension 5 and an airbag suspension 7, wherein at least one of the leaf spring suspension 5 and the airbag suspension 7 is detachably connected to a connecting structure 4.

[0090] Understandably, the connecting structure 4 at the frame is detachably connected to the leaf spring suspension 5, allowing the leaf spring suspension 5 to be detachably connected to the frame. In other words, when it needs to be adapted to the leaf spring suspension 5 system, it can be connected to the leaf spring suspension 5 using the connecting structure 4. When it needs to be adapted to other suspension systems, the leaf spring suspension 5 can be detached from the frame to allow other suspension systems to be installed on the frame. This makes the frame compatible with various suspension systems, improving its adaptability.

[0091] In some embodiments, the chassis assembly includes at least one of a bumper bracket, a body mount, a tow hook, a protective bracket, and a steering gear bracket.

[0092] In some embodiments, see Figure 1 and Figure 2The leaf spring suspension 5 includes a mounting base 51 and a leaf spring 52. The leaf spring 52 is connected to the mounting base 51, and the mounting base 51 is detachably connected to the connecting structure 4.

[0093] It is understandable that the mounting base 51 is detachably connected to the connecting structure 4, that is, the leaf spring suspension 5 can be detachably connected to the vehicle frame. Thus, it is possible to choose whether to connect the leaf spring suspension 5 to the vehicle frame according to actual needs, thereby improving the adaptability of the vehicle frame.

[0094] According to a third aspect of this application, this application provides a vehicle including the aforementioned frame or frame assembly.

[0095] Understandably, the connecting structure 4 at the frame is detachably connected to the leaf spring suspension 5, allowing the leaf spring suspension 5 to be detachably connected to the frame. In other words, when it needs to be adapted to the leaf spring suspension 5 system, it can be connected to the leaf spring suspension 5 using the connecting structure 4. When it needs to be adapted to other suspension systems, the leaf spring suspension 5 can be detached from the frame to allow other suspension systems to be installed on the frame. This makes the frame compatible with various suspension systems, improving its adaptability.

[0096] In some examples, the vehicle may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this application does not specifically limit this.
