[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] In order to solve the technical problems in the existing technology of low vehicle versatility, low development efficiency, and disadvantages for large-scale development and cost control, the present invention provides a vehicle architecture combination structure, which can make some architecture modules applicable to multiple vehicle models, that is, without changing the boundaries and interfaces of the architecture modules, and quickly realize the docking of modules, and realize modular combination of different needs, thereby improving the versatility and development efficiency of vehicle models, facilitating large-scale development and cost control, and forming an efficient architecture platform.

[0036] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 This is a structural schematic diagram of a vehicle architecture combination structure in an embodiment of the present invention. The vehicle architecture combination structure includes multiple groups of vehicle model units and multiple groups of connection units. The vehicle model units of each group include multiple architecture modules 1. The multiple architecture modules 1 of the same group can be arranged according to preset positions and assembled into the body of the vehicle model to which they belong, and at least one architecture module 1 can be applied to the vehicle model units of other groups. When applied to the vehicle model units of other groups, it can replace the same type of architecture module 1 of other groups, and together with multiple architecture modules 1 of the remaining types of other groups, it constitutes the body of the vehicle model to which the other groups belong; multiple groups of connection units are respectively provided in the multiple groups of vehicle model units, for connecting two adjacent architecture modules 1 of each group, and the connection units of multiple groups are the same.

[0037] In the vehicle architecture combination structure provided by the present invention, each group of vehicle model units includes multiple architecture modules 1. Multiple architecture modules 1 in the same group can be assembled into the body of the corresponding vehicle model. At the same time, because multiple vehicle model units are connected to two adjacent architecture modules 1 within the group through the same connecting unit, and the architecture modules 1 within a group are applicable to vehicle model units in other groups, the architecture modules 1 within a group can also be assembled with architecture modules 1 in other groups to form the body of the vehicle model of the other group. In this way, by setting the control points of the architecture modules 1 and the interface elements between modules, this solution can make some architecture modules 1 applicable to multiple vehicle models. That is, without changing the boundaries and interfaces of the architecture modules 1, the modules can be quickly connected, and modular combinations with different needs can be realized, improving the versatility and development efficiency of vehicle models, facilitating large-scale development and cost control, and forming an efficient architecture platform.

[0038] It should be noted that, in one embodiment, the multiple architecture modules 1 are a cab module 10, a chassis module 20, a powertrain module 30, a front axle front suspension module 40, a rear axle rear suspension module 50 and a superstructure module. The cab module 10 is connected to the front end of the chassis module 20, the powertrain module 30 is installed on the chassis module 20, the front axle front suspension module 40 and the rear axle rear suspension module 50 are respectively arranged at the front and rear ends of the chassis module 20, and the superstructure module is arranged between the cab module 10 and the chassis module 20.

[0039] In this embodiment, the vehicle is divided into the following modules: a cab module 10, a chassis module 20, a powertrain module 30, a front axle front suspension module 40, a rear axle rear suspension module 50, and a superstructure module. Each module contains electronic and electrical components and interfaces arranged therein. The cab module 10 mainly includes the body-in-white and the cab suspension system. The chassis module 20 mainly includes the frame system. The powertrain module 30 mainly includes the engine, transmission assembly, powertrain suspension system, and engine cooling module. The front axle front suspension module 40 mainly includes the front axle, wheel assembly, and front suspension system. The rear axle rear suspension module 50 mainly includes the rear axle and rear suspension system. The superstructure module focuses on the boundary 60 of the superstructure module, specifically including the front boundary of the superstructure related to the cab module 10, and the lower boundary related to the chassis module 20.

[0040] Furthermore, the chassis module 20 and the rear axle rear suspension module 50, using the balancing suspension as an example, use the rear suspension thrust rod as the docking interface. The rear suspension upper thrust rod is bolted to the rear axle at one end and to the frame thrust rod support at the other end. The rear suspension lower thrust rod is bolted to the rear axle at one end and to the frame balancing suspension support at the other end. The upper thrust rod can adopt a straight-thrust, V-shaped, or X-shaped structure.

[0041] See also Figure 9 The chassis module 20 and the powertrain module 30 use the powertrain mount as the interface. The powertrain mount bracket is bolted to the powertrain, while the powertrain mount bracket is bolted to the vehicle frame with bolts or rivets. The powertrain bracket and bracket are bolted together. The powertrain mount can be arranged in a three-point or four-point configuration, with both front and rear mounts located on the engine assembly, or separately on the engine assembly and the transmission clutch assembly.

[0042] In one embodiment, a connection position is formed between two adjacent building modules 1 in the same group. Each connection unit includes a plurality of connection parts 21. The plurality of connection parts 21 are respectively provided at the plurality of connection positions for connecting the corresponding two adjacent building modules 1.

[0043] In this embodiment, the connection unit is configured as a plurality of connection portions 21, and the plurality of connection portions 21 are positioned between a plurality of adjacent structural modules 1 of the same type in the same group to achieve connection between the two adjacent structural modules 1. It should be noted that the configuration of the various connection portions 21 in the same group can be different or the same. In one embodiment, the connection portions 21 are configured in the form of bolts and nuts and inserted into holes in the corresponding structural modules 1 to achieve connection; in another embodiment, the connection portions 21 are configured in the form of leaf springs 28; and in other embodiments, the connection portions 21 are configured in the form of anchors. It should be understood that the configuration of the connection portions 21 between two adjacent structural modules 1 of the same type in different groups is the same.

[0044] In one embodiment, see Figures 3 to 5 At least one connecting portion 21 includes a mounting shaft 22, a positioning bowl 23, a positioning column 24 and a connecting piece. The mounting shaft 22 is rotatably mounted on the structural module 1. The positioning bowl 23 is mounted on the mounting shaft 22, and the opening is parallel to the axis of the mounting shaft 22. The positioning column 24 is mounted on the adjacent structural module 1 and can be inserted into the positioning bowl 23. The connecting piece is provided on the positioning column 24 and can be connected to the mounting shaft 22 when the positioning column 24 is inserted into the positioning bowl 23.

[0045] In this embodiment, the connection portion 21 is configured as described above, so that when a structural module 1 is positioned adjacent to an adjacent structural module 1, the positioning post 24 can be inserted into the positioning bowl 23, thereby driving the mounting shaft 22 to rotate. As the structural module 1 falls into place, the connector can precisely connect the two structural modules 1, improving assembly convenience. It should be noted that in one embodiment, the two structural modules 1 are the cab module 10 and the chassis module 20.

[0046] It should be noted that there is no limitation on the form of the connector, as long as it can achieve the connection between two adjacent structural modules 1. In one embodiment, the connector is configured as an anchor; in another embodiment, the connector is configured as a locking pin.

[0047] In one embodiment, mounting holes 22a are provided at both ends of the mounting shaft 22, and a connecting arm 221 is provided at one end extending radially thereof, the positioning bowl 23 is mounted on the connecting arm 221, the positioning column 24 includes a seat section 241 and a column section 242 connected to each other, the seat section 241 is mounted on the corresponding structural module 1, and a matching hole 241a is provided corresponding to the mounting hole 22a, and the column section 242 can be inserted into the positioning bowl 23; the connecting part includes a connecting bolt and a connecting nut, the connecting bolt is passed through the matching hole 241a and the mounting hole 22a, and the connecting nut is screwed on the connecting bolt.

[0048] In this embodiment, when the column section 242 contacts the positioning bowl 23 and drives the mounting shaft 22 to rotate to the position where the cab falls into place, the matching hole 241a on the seat section 241 is exactly aligned with the mounting hole 22a on the mounting shaft 22, and then the connecting bolt is passed through the matching hole 241a and the mounting hole 22a, and the connecting bolt is tightened to realize the connection between the two modules.

[0049] In one embodiment, the positioning column 24 further includes a connecting bracket 243 , which is connected to the base section 241 and has a fixing bracket spaced apart from the column section 242 , and the fixing bracket is provided with a hole.

[0050] In this embodiment, a connecting bracket 243 is also provided on the seat section 241, and the corresponding module to be assembled is installed. When the cab module 10 is lowered into place, the connecting bracket 243 can also be quickly connected to other mechanisms, further improving assembly convenience. Specifically, in this embodiment, the connecting bracket 243 is used to connect to the shock absorber.

[0051] In one embodiment, see Figure 4 and Figure 6 The connection portion 21 is further provided with a limiting seat 25 and a limiting column 26 corresponding to the mounting axis 22. The limiting seat 25 and the limiting column 26 are respectively provided at two adjacent structural modules 1. The limiting seat 25 is provided with a limiting groove 25a for the limiting column 26 to pass through.

[0052] In this embodiment, the axial direction of the limiting post 26 is aligned with the axial direction of the mounting shaft 22, and the limiting seat 25 is spaced behind the mounting shaft 22. This allows the positioning bowl 23 and the positioning post 24 to constrain the falling direction of the cab module 10, allowing it to tilt and descend along with the rear portion of the cab module 10, improving convenience. Specifically, in this embodiment, the limiting groove 25a utilizes a V-shaped locking interface, allowing the rear suspension upper bracket of the cab module 10 to drop and automatically snap into place within the range of the V-shaped interface.

[0053] In one embodiment, see Figure 7 At least one connecting portion 21 includes a leaf spring support 27, a leaf spring 28 and a leaf spring pin 29. The leaf spring support 27 is installed on the structural module 1 and has a mounting groove. One end of the leaf spring 28 is bent and formed with a coiled ear channel and penetrates the mounting groove. The other end is connected to the adjacent structural module 1. The leaf spring pin 29 is installed on the leaf spring support 27 and penetrates the coiled ear channel to press the leaf spring 28 against the leaf spring support 27.

[0054] In this embodiment, the connection portion 21 between the two architectural modules 1 is provided in the form of a leaf spring 28. Specifically, the two architectural modules 1 are the chassis module 20 and the front axle front suspension module. The leaf spring support 27 is fixed to the longitudinal beam of the chassis module 20 with bolts or rivets, and is connected to the ear section of the leaf spring 28 by a leaf spring pin 29.

[0055] The present invention further provides a vehicle architecture assembly method for the vehicle architecture assembly structure described above. An embodiment of the vehicle architecture assembly method includes the following steps:

[0056] Obtaining control points and parameters of various architecture modules 1 of each group to form a module database;

[0057] When selecting an adaptation module, the control points and parameters of the architecture module 1 to be selected are obtained, and the module database is searched according to the control points of the architecture module 1 to be selected to extract architecture modules 1 having the same control points as the architecture module 1 to be selected;

[0058] The parameters of the architecture module 1 to be selected are compared with the parameters of the extracted architecture module 1. When the parameters of the extracted architecture module 1 are the same as those of the architecture module 1 to be selected, the extracted architecture module 1 is determined to be an adaptation module.

[0059] In this embodiment, a database of all modules is first constructed, and the modules of each vehicle unit are numbered. This allows the control points and parameters of the module to be selected based on the number of the architecture module 1 to be selected. The module database is then searched and analyzed to identify architecture modules 1 with the same control points, and the corresponding parameters are extracted. The parameters of the architecture module 1 to be selected are then compared with the parameters of the retrieved architecture modules 1. Architecture modules 1 with identical parameters are identified as compatible modules. If no compatibility exists, a "no match" message is displayed.

[0060] It should be noted that, in one embodiment, the control points of each module are as follows:

[0061] Cab module 10: body-in-white dimensions, floor and bulge dimensions, cab front and rear overhang span and footprint.

[0062] Chassis module 20: outer width of the frame assembly, height of the longitudinal beam belly, connection interfaces of the front and rear suspensions of the cab on the frame, connection interfaces of the powertrain suspension on the frame, connection interfaces of the front suspension on the frame, and connection interfaces of the rear suspension on the frame.

[0063] Powertrain module 30: engine assembly envelope, transmission assembly envelope, powertrain cooling module location and envelope.

[0064] Front axle front suspension module 40: front suspension length, tire envelope, front suspension movement space, wheelbase between front axles.

[0065] Rear axle rear suspension module 50: rear suspension type, connection interface with the frame, and wheelbase between rear axles.

[0066] Upper body module: Carriage front panel positioning, trailer front turning radius, chassis components can extend beyond the upper wing height of the frame.

[0067] The relative positions of the front axle front suspension module 40 and the rear axle rear suspension module 50 on the vehicle, namely the intermediate wheelbase, are set as variable parameters, driven by serialization rules to achieve the module layout for different vehicle lengths. Deformations of the architecture module 1 that meet interface definitions and do not exceed the envelope boundaries are interchangeable, forming vehicle variants and product series within the same architecture. The electronic and electrical components and interfaces contained in the architecture module 1 also conform to the definition of interface modularization and standardization, enabling electrical and signal interoperability during module interchange.

[0068] In addition, the present aspect also provides a vehicle architecture combination control device, which includes: a memory, a processor, and a vehicle architecture combination method control program stored in the memory and executable on the processor. When the vehicle architecture combination method control program is executed by the processor, the steps of the vehicle architecture combination method described above are implemented.

[0069] In order to better understand the present invention, the following Figures 1 to 9 The technical solution of the present invention is described in detail:

[0070] For ease of understanding, this article divides the chassis module 20 into four virtual modules: front, middle, rear, and tail. The interfaces between the front and rear virtual modules are relatively fixed. The front virtual module includes the interface components for the cab module, powertrain module, and front axle and front suspension module, with the rear cross member of the transmission serving as the dividing point.

[0071] The rear virtual module includes the rear suspension module docking interface components, with the front and rear cross members of the rear suspension as segmentation points.

[0072] The central virtual module can be lengthened in 50mm increments based on market demand, enabling rapid evolution of models with different wheelbases. The central cross member can be increased or decreased in length depending on the module.

[0073] The rear dummy module extends from the rear suspension's rear crossmember to the tail crossmember, and can be modified to suit the body type. For trailers, a short rear overhang and dovetail beam are used. For vans, the rear dummy module is relatively long. The tail crossmember increases or decreases with module length.

[0074] This solution features an architecture module 1 configurator. Key control points for architecture module 1 are stored in a database, which primarily records key control points, parameters, and matching relationships. The configurator can be used to select corresponding architecture modules 1 based on the input architecture module 1, storing the newly modified architecture module 1, submodules, control points, parameters, and matching relationships.

[0075] If you need to add a new module transformation, complete the module transformation and parameter entry, and then re-enter the process. If you agree to adjust the module, check the matching module number and the matching architecture module 1 will be output.

[0076] Thus, the commercial vehicle structure is divided into the following common architectural modules: cab module 10, chassis module 20, powertrain module 30, front axle front suspension module 40, rear axle rear suspension module 50, and bodywork module. Key control points, inter-module interface elements, and connection and positioning structures are defined for architectural module 1. Without changing the boundaries and interfaces of architectural module 1, modules can be quickly integrated, enabling modular combinations tailored to specific needs to form an architectural platform.

[0077] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
