[0002] As the core skeleton of a vehicle, the chassis bears the heavy responsibility of supporting and connecting various key components. Its structural design and manufacturing process directly determine the vehicle's safety, comfort, and handling performance. However, in traditional automobile manufacturing, chassis design and manufacturing are often customized for specific models, resulting in chassis that are not interchangeable between different models. This not only increases research and development and production costs but also limits the improvement of manufacturing efficiency. Utility Model Content

[0039] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0041] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0042] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0043] In the embodiments of this application, "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, the range of which is within an acceptable deviation range, said acceptable deviation range being determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range for approximate parallelism may be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range for approximate perpendicularity may also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0044] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0045] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0046] In some embodiments, this application provides a vehicle including a frame, which is the basic structure of the vehicle and bears the weight of vehicle components such as the engine, transmission, suspension system, and body.

[0047] The vehicle in this application can be an electric vehicle or a hybrid electric vehicle, etc. For example, the vehicle can be a passenger car such as a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV), or it can be a bus, a truck, a semi-trailer, etc. This application does not impose specific limitations in this regard.

[0048] In some embodiments, please refer to Figure 1 The vehicle also includes a chassis 100, which includes a frame. The frame is the core skeleton of the chassis 100, providing support and connection for the chassis 100 system.

[0049] In other embodiments, please refer to Figure 1 The vehicle also includes a beam assembly, which forms a component of the frame or chassis 100. The beam assembly can be assembled into the frame or chassis 100 to provide support for the vehicle's components.

[0050] For example, the vehicle beam assembly can withstand the weight from the engine, transmission, body, passengers and cargo, as well as various forces and torques generated during driving.

[0051] Of course, the vehicle beam assembly mentioned in this application is illustrated by the vehicle beam on the chassis 100. The vehicle beam assembly may also include A-pillars, B-pillars and roof longitudinal beams, etc.

[0052] In some embodiments, see Figure 1 The chassis 100 in this application includes a front beam assembly 101, a front wheel frame assembly 102, a middle beam assembly 103, a rear wheel frame assembly 104, and a rear beam assembly 105 connected sequentially along the length of the vehicle. This modular design allows the chassis 100 to be divided into different modules according to function, each module responsible for a specific function. For example, the front beam assembly 101 supports the engine and front suspension, the front wheel frame assembly 102 mounts the front wheels and steering system, the middle beam assembly 103 supports the front and rear compartments of the vehicle, the rear wheel frame assembly 104 mounts the rear wheels and steering system, and the rear beam assembly 105 supports the vehicle's trunk.

[0053] Of course, different modules can be further divided, but this application does not limit this.

[0054] For example, the intermediate beam assembly 103 may also include a first intermediate beam assembly 103 and a second intermediate beam assembly 103 connected sequentially along the length of the vehicle.

[0055] Building upon this, the modular design of this application makes the frame design more standardized and regulated, reducing repetitive design work, shortening the production cycle, and improving production efficiency. Furthermore, each module can be designed, developed, and manufactured independently, improving R&D efficiency and manufacturing flexibility.

[0056] Another example, taking the vehicle's length direction as an example, the boundaries of each component along the vehicle's length direction are defined by its corresponding front and rear crossbeams. Specifically, the front end of the front beam assembly 101 is bounded by the frontmost front crossbeam of the vehicle, and its rear end connects to the front crossbeam of the front wheel frame assembly 102. The front end of the front wheel frame assembly 102 connects to the rear crossbeam of the front beam assembly 101, and its rear end connects to the front crossbeam of the middle beam assembly 103. The front end of the middle beam assembly 103 connects to the rear crossbeam of the front wheel frame assembly 102, and its rear end connects to the front crossbeam of the rear wheel frame assembly 104. The front end of the rear wheel frame assembly 104 connects to the rear crossbeam of the middle beam assembly 103, and its rear end connects to the front crossbeam of the rear beam assembly 105. The front end of the rear beam assembly 105 connects to the rear crossbeam of the rear wheel frame assembly 104, and its rear end is bounded by the rearmost rear crossbeam of the vehicle.

[0057] In some embodiments, this application also provides a vehicle beam assembly applied to a vehicle.

[0058] For example, at least one of the front beam assembly 101, the front wheel frame assembly 102, the middle beam assembly 103, the rear wheel frame assembly 104, and the rear beam assembly 105 includes the beam assembly.

[0059] In some embodiments, please refer to Figure 2 The vehicle beam assembly in this application includes a first vehicle beam 200 and a second vehicle beam 300. The second vehicle beam 300 is connected to the first vehicle beam 200. The extension direction of the second vehicle beam 300 intersects the extension direction of the first vehicle beam 200. The second vehicle beam 300 includes at least one first telescopic beam. The first telescopic beam is adapted to change its length along the extension direction of the second vehicle beam 300 under the action of external force.

[0060] The second beam 300 intersects and connects with the first beam 200. The second beam 300 and the first beam 200 can be arranged perpendicularly, and the included angle between the second beam 300 and the first beam 200 can be an acute angle or an obtuse angle. This application uses the perpendicular arrangement of the second beam 300 and the first beam 200 as an example. In this way, the first beam 200 can provide a stable base for the second beam 300 to expand and contract.

[0061] The first telescopic beam included in the second beam 300 can vary in length along the extension direction of the second beam 300, so that the length of the second beam 300 can be adjusted according to actual needs. This allows the beam assembly to be adjusted according to different vehicle models to meet the needs of different models, thus expanding the applicability of the beam assembly.

[0062] In some embodiments, please refer to Figure 3 , Figure 4 as well as Figure 5 , Figure 3 , Figure 4 as well as Figure 5 for Figure 1 The schematic diagram of the chassis 100 shown depicts a first beam 200 extending along the width of the vehicle, and a first telescopic beam (i.e., the second beam 300) extending along the length of the vehicle. Thus, the second beam 300 serves as the vehicle's longitudinal beam, and the first beam 200 serves as the vehicle's transverse beam. Through the design of the first telescopic beam, the second beam 300 can adapt to different vehicle wheelbases and optimize the structure of the chassis 100. In other words, by adjusting the length of the first telescopic beam, the second beam 300 can quickly adapt to vehicles with different wheelbases, shortening the development cycle and reducing production costs.

[0063] Of course, the first beam 200 can also extend along the length of the vehicle, and the second beam 300 can extend along the width of the vehicle; this application does not limit this.

[0064] In other embodiments, the first beam 200 includes at least one second telescopic beam adapted to change length along the extension direction of the first beam 200 under the action of external force. This application uses the first beam 200 forming a crossbeam of a vehicle as an example, thus enabling the first beam 200 to adapt to the width requirements of different vehicle models during vehicle production, further improving the versatility of the beam assembly.

[0065] Meanwhile, the presence of the first or second telescopic beam allows for flexible adjustment of the frame structure, thereby meeting the frame's error adjustment requirements on the vehicle chassis 100 and effectively compensating for these errors.

[0066] The structures of the first and second telescopic beams in this application may be the same or different, and this application does not limit this.

[0067] In some embodiments, please refer to Figure 6 and combined Figure 1 and Figure 2The first telescopic beam includes a first sub-beam 301 and a second sub-beam 302. One end of the first sub-beam 301 is connected to the first vehicle beam 200, and the second sub-beam 302 is connected to the side of the first sub-beam 301 away from the first vehicle beam 200. The second sub-beam 302 is adapted to move in a direction toward or away from the first vehicle beam 200 under the action of external force, and the second sub-beam 302 is adapted to be fixed relative to the second vehicle beam 300 in a preset position.

[0068] For example, the second sub-beam 302 is located on one side of the first sub-beam 301 along the vehicle height direction; in another example, the second sub-beam 302 is located on one side of the first sub-beam 301 along the vehicle width direction.

[0069] The second sub-beam 302 can move towards or away from the first beam 200, thereby enabling flexible adjustment of the overall length of the first telescopic beam to adapt to the wheelbase requirements of different vehicle models. The second sub-beam 302 is fixed relative to the second beam 300 in a preset position, ensuring the accuracy and reliability of the first telescopic beam length adjustment.

[0070] For example, the second sub-beam 302 is relatively fixed in a preset position by welding it to the second vehicle beam 300.

[0071] In some embodiments, please refer back to the reference. Figure 4 and combined Figure 6 The vehicle beam assembly also includes a third vehicle beam 500, which is spaced apart from the first vehicle beam 200 along the length of the vehicle. Taking the first vehicle beam 200 as an example, the third vehicle beam 500 is also a crossbeam of the vehicle. A first telescopic beam connects the first vehicle beam 200 and the third vehicle beam 500. When the distance between the third vehicle beam 500 and the first vehicle beam 200 is a preset distance, the length of the first telescopic beam is consistent with the preset distance.

[0072] In this way, the length of the first telescopic beam can be precisely adjusted according to the preset distance. By adjusting the length of the first telescopic beam, the distance between the third beam 500 and the first beam 200 can be flexibly changed, thereby adapting to the chassis 100 size requirements of different vehicle models.

[0073] Of course, the first telescopic beam can also be connected between the first vehicle beam 200 and other components to adjust the spacing between the first vehicle and other components.

[0074] In some embodiments, the end of the second sub-beam 302 opposite to the first sub-beam 301 is connected to the third beam 500.

[0075] For example, the end of the second sub-beam 302 facing away from the first sub-beam 301 is welded to the third beam 500. That is, the positional relationship between the third beam 500 and the first beam 200 can be adjusted by adjusting the relative positional relationship between the second sub-beam 302 and the first sub-beam 301, which is simple in structure and easy to produce.

[0076] In other embodiments, the telescopic beam further includes a third sub-beam connected to the third vehicle beam 500, and a second sub-beam 302 connected between the third sub-beam and the first sub-beam 301. The second sub-beam 302 is adapted to move in a direction toward or away from the third vehicle beam 500 under the action of an external force, and the second sub-beam 302 is adapted to be fixed relative to the third vehicle beam 500 at a preset position.

[0077] In this way, the relative position between the second sub-beam 302 and the third beam 500 can be further adjusted with the presence of the third sub-beam. This allows the same set of beam components to be quickly adapted to the chassis 100 structure of various vehicle models.

[0078] This application illustrates the example of a second sub-beam 302 being directly connected to a third sub-beam.

[0079] In some embodiments, please refer to Figure 6 and combined Figure 4 The plane perpendicular to the width direction of the vehicle is the first reference plane. The projection of the first sub-beam 301 onto the first reference plane is the first projection. The projection of the second sub-beam 302 onto the first reference plane is the second projection. When the second sub-beam 302 moves toward the first vehicle beam 200, the first projection at least partially falls into the second projection.

[0080] When the second sub-beam 302 moves toward the first beam 200, the first projection at least partially falls within the second projection. This means that the beam assembly can be more compact in the width direction, reducing unnecessary space occupation. At the same time, when the first projection falls within the second projection, the first sub-beam 301 and the second sub-beam 302 form a stronger connection in the overlapping area, improving the overall rigidity and torsional resistance of the frame.

[0081] In some embodiments, please refer to Figure 6 and combined Figure 1 and Figure 2 The second sub-beam 302 includes a body, which has a cavity and an opening connecting the cavity to the outside. The opening is positioned facing the first sub-beam 301, and the first sub-beam 301 is adapted to extend into or detach from the cavity through the opening.

[0082] When the first sub-beam 301 extends into the cavity of the second sub-beam 302, a tight connection is formed between the two, improving the overall rigidity and torsional resistance of the frame. By adjusting the depth of the first sub-beam 301 extending into the cavity, the overall dimensions of the frame can be flexibly changed to adapt to the chassis 100 structure of different vehicle models. Simultaneously, with the first sub-beam 301 extending into the cavity of the second sub-beam 302, the beam assembly becomes more compact in the width direction, reducing unnecessary space occupation. In this way, this application significantly reduces research and development and production costs, improves manufacturing efficiency, and enhances the flexibility and adaptability of the frame.

[0083] In some embodiments, please refer to Figure 6 and combined Figure 4 The vehicle beam assembly also includes a first reinforcing member 400, which connects the second sub-beam 302 and the first vehicle beam 200. When the second sub-beam 302 is adjusted to a preset position, the first reinforcing member 400 fixes the second sub-beam 302 to the first vehicle beam 200, preventing it from moving and allowing the vehicle beam assembly to be adjusted to fit the corresponding target vehicle model.

[0084] Meanwhile, the first reinforcing member 400 can also enhance the structural strength between the second sub-beam 302 and the first vehicle.

[0085] For example, the first reinforcement 400 can be a welded component.

[0086] Of course, the beam assembly may also include multiple first reinforcing members 400, and the first reinforcing members 400 may also be located in other parts of the vehicle (such as the connection points of other vehicles), which is not limited in this application.

[0087] In some embodiments, the beam assembly further includes a second reinforcement member connected between the second sub-beam 302 and the third beam 500.

[0088] The second reinforcing member forms additional support between the second sub-beam 302 and the third beam 500, and works together with the first reinforcing member 400 to significantly enhance the overall rigidity and torsional resistance of the frame.

[0089] The structure of the first reinforcing member 400 may or may not be the same as that of the second reinforcing member, and this application does not impose any restrictions.

[0090] Of course, the first reinforcing member 400 in this application can also be provided between the original longitudinal beams and transverse beams of the vehicle to strengthen the connection strength between the beam assemblies.

[0091] It should be noted that the first reinforcing member 400 and the second reinforcing member may have corresponding dimensional changes depending on their specific installation location, and this application does not limit them in this regard.

[0092] In some embodiments, please refer to Figure 6 and combined Figure 7 The first sub-beam 301 includes a first part and a second part connected to each other. The first part is located in the cavity, and the second part is located between the second sub-beam 302 and the first vehicle beam 200. The vehicle beam assembly also includes a first reinforcing member 400, which is connected between the second sub-beam 302 and the first vehicle beam 200, and is connected to the second part.

[0093] In this way, the first reinforcing member 400 can simultaneously connect the first sub-beam 301, the second sub-beam 302, and the first vehicle beam 200. Through multi-point connection, the first reinforcing member 400 can better distribute and transfer the load, reduce local stress concentration, and extend the service life of the vehicle frame.

[0094] In some embodiments, please refer to Figure 7 and combined Figure 8 The first reinforcing member 400 includes a first connecting portion 401 and a second connecting portion 402. The first connecting portion 401 is adapted to be connected to the second sub-beam 302. The second connecting portion 402 is connected to one end of the first connecting portion 401 facing the first vehicle beam 200, and the second connecting portion 402 is connected to the first vehicle beam 200.

[0095] Of course, the first connecting part 401 can also be connected to the first sub-beam 301.

[0096] When the first beam 200 is a crossbeam of the vehicle and the second beam 300 is a longitudinal beam, the first reinforcing member 400 can be an L-shaped structural component that connects to both the first beam 200 and the second sub-beam 302. This effectively improves the connection strength and rigidity between the first reinforcing member 400, the second sub-beam 302, and the first beam 200, preventing loosening or deformation at the connection. Furthermore, the first connecting part 401 and the second connecting part 402 are respectively connected to the second sub-beam 302 and the first beam 200, forming a double connection structure, further improving the reliability and stability of the connection.

[0097] In some embodiments, please refer to Figure 7 and combined Figure 8 At least one of the first connecting portion 401 and the second connecting portion 402 is provided with at least one plug weld hole 403.

[0098] Plug welding is a connection method in which solder is filled into pre-drilled holes and then welded. The plug weld hole 403 increases the welding area, improves the connection strength between the first reinforcing member 400 and the second sub-beam 302 or the first vehicle beam 200, and prevents loosening or breakage at the connection. Furthermore, by providing the plug weld hole 403, the weight of the first reinforcing member 400 can be reduced, meeting the requirements for vehicle lightweighting.

[0099] In some embodiments, please refer to Figure 7 and combined Figure 8 At least one of the first connecting portion 401 and the second connecting portion 402 is provided with at least one riveting hole 404.

[0100] Riveting is a mechanical connection method that uses rivets to join two or more parts together. The rivet hole 404 can easily install rivets. By setting the rivet hole 404, the connection reliability between the first reinforcing member 400 and the second sub-beam 302 or the first vehicle beam 200 can be improved, preventing loosening or detachment at the connection.

[0101] In some embodiments, please refer to Figure 7 and combined Figure 8 The first connecting part 401 is connected to one side of the second sub-beam 302 along the vehicle width direction, and the second connecting part 402 is connected to one side of the first beam 200 along the vehicle length direction.
