Description

Technical Field

[0001] The present application belongs to the field of vehicle structure design and manufacturing technology, and in particular, relates to an integrated crossbeam component, a chassis assembly and a vehicle. Background Art

[0002] The air tank is a key component in the air suspension system, which is mainly used to store compressed air and provide stable air pressure for the air suspension. This air pressure is used to control the height, rigidity and damping of the suspension, thereby optimizing the vehicle's handling, comfort and stability.

[0003] Under the existing technical framework, the air storage tank of the air suspension is usually designed as an independent component, and its placement is mostly limited to the trunk or under the rear floor (such as Figure 1 ). In addition, it may also be fixed on the crossbeam or longitudinal beam of the vehicle body or frame. This layout means that the volume of the gas tank is strictly limited, because too large a volume will encroach on the trunk space. More importantly, since the gas tank is set at the rear of the vehicle, there is a risk of explosion in the event of a collision, which undoubtedly poses a hidden danger to the safety of the vehicle.

[0004] At the same time, the installation locations of key components such as the electronic air pump, gas circuit solenoid distribution valve assembly, electronic water pump, and air conditioning compressor are also different, and may be scattered in multiple parts such as the subframe, powertrain, and body. This decentralized layout makes it difficult to unify the final assembly strategy, which not only increases the complexity of assembly, but also requires new structural designs or continued bracket fixation for the decentralized components during the product design process, which will directly increase the product's early development costs and the later mass production vehicle manufacturing costs.

[0008] In an optional solution of the present application, a distribution valve mounting hole is provided at one end of the integrated bracket along the X direction, and the air circuit electromagnetic distribution valve assembly is connected to the integrated bracket through the distribution valve mounting hole; wherein, the beam structure also includes a step shaft and an air storage pipeline, the step shaft is connected to the cavity structure inside the beam structure, and the air circuit electromagnetic distribution valve assembly is connected to the step shaft and the electronic air pump through the air storage pipeline.

[0009] In a further solution of the present application, the integrated crossbeam assembly also includes an air-conditioning compressor, the mounting hole group includes a plurality of compressor mounting holes, and the compressor mounting holes are arranged on the side wall of the integrated bracket; the air-conditioning compressor is connected to the crossbeam structure along the extension direction of the crossbeam structure through the compressor mounting holes.

[0010] In a further solution of the present application, the integrated crossbeam assembly also includes an electronic water pump, and a water pump mounting hole is provided at the other end of the integrated bracket along the X direction, and the electronic water pump is connected to the integrated bracket through the water pump mounting hole.

[0011] In a further solution of the present application, the interior of the integrated bracket is hollowed out and provided with a plurality of bracket reinforcing ribs.

[0012] In a further solution of the present application, the beam structure includes a beam body and a connector; the beam body is a hollow structure with openings at both ends, and the connector is arranged at two ends of the beam body; wherein the connector includes a connecting plate and an ear plate, wherein the connecting plate is closed at the opening at the end of the beam body, and the ear plate extends in a direction away from the beam body.

[0013] In a further solution of the present application, at least one beam reinforcement rib is arranged inside the beam body.

[0014] In a second aspect of the present application, a chassis assembly is also provided, comprising the integrated cross beam assembly as described above; and further comprising: a longitudinal beam assembly, wherein the integrated cross beam assembly is connected to the longitudinal beam assembly.

[0015] Finally, the present application also provides a vehicle, which also includes the above chassis assembly.

[0016] In summary, the integrated crossbeam assembly provided by the present application includes an integrated bracket, a crossbeam structure and an air supply device; wherein the integrated bracket is connected to the crossbeam structure, and the air supply device includes an air circuit electromagnetic distribution valve assembly and an electronic air pump connected to the cavity structure; the air circuit electromagnetic distribution valve assembly and the electronic air pump are connected to the integrated bracket through a mounting hole group provided on the integrated bracket, and have at least the following technical effects:

[0017] 1. The interior of the crossbeam structure is designed as a sealed cavity structure to store the high-pressure air required by the air suspension system. This design ensures that the air suspension system has a stable air supply. By storing air inside the crossbeam, the vehicle's space layout is optimized, the trunk space occupied is reduced, and the space utilization rate of the vehicle is improved;

[0018] 2. In traditional vehicle designs, the gas tank is usually placed in the trunk or under the trunk floor, which takes up a lot of trunk space. This application combines the gas supply device with the crossbeam structure, and the crossbeam structure replaces the gas tank, which not only improves the space utilization rate, but also improves the safety performance of the entire vehicle. The gas supply device is integrated into the crossbeam structure, making it a part of the vehicle body structure, which means that in the event of a collision, the gas tank is no longer an independent component in the trunk or under the floor, so the possibility of damage in a collision is greatly reduced, thereby reducing the risk of explosion caused by damage to the gas supply device;

[0019] 3. Highly integrated design means that multiple components and functions are integrated into one component, which greatly reduces the steps and complexity of the assembly process. On the production line, this integrated design allows for a faster and more efficient assembly process. For example, by pre-installing integrated beam components and performing final assembly on the general assembly line, the factory can further improve production efficiency and shorten the overall production cycle;

[0020] 4. The entire integrated crossbeam assembly is located at the front of the vehicle, which not only simplifies the assembly process, but also helps optimize the wiring harness layout. All wiring harnesses related to the air supply device and electronic components can be more direct, reducing confusion and potential interference. The front position is also more conducive to the gas distribution and management of the air suspension system. Since there is a cavity structure inside the crossbeam structure for storing high-pressure air, and the electronic air pump and other related components are integrated together, the distribution and flow of gas become more direct and efficient;

[0021] 5. The gas circuit electromagnetic distribution valve assembly and the electronic air pump are connected to the integrated bracket from different installation positions through the installation holes, thereby realizing flexible application of space and saving the overall space of the integrated crossbeam assembly.

[0022] Other features and advantages of the embodiments of the present application will be described in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] See also Figure 2 and Figure 3 , Figure 2 The utility model is exemplarily provided as a structural schematic diagram of an integrated beam assembly 100 in an assembled state; Figure 3 It is an exploded schematic diagram of the integrated crossbeam assembly 100 provided in an embodiment of the present utility model.

[0049] The integrated cross beam assembly 100 includes an integrated bracket 10, a cross beam structure 20 and an air supply device 30. Specifically, the cross beam structure 20 is the main load-bearing part of the integrated cross beam assembly 100, extending along the Y direction of the vehicle body coordinate system, with a length direction perpendicular to the length direction of the vehicle, and is used to provide installation and support.

[0050] The interior of the cross beam structure 20 is a cavity structure for storing air, and the air is used to adjust the height and suspension stiffness of the vehicle. In other words, the present application uses the cross beam structure 20 as an air storage container to store and supply the required compressed air through its internal cavity, thereby optimizing the layout of the vehicle, more effectively utilizing the space inside the vehicle, improving the integration level of the vehicle, improving the space utilization rate of the vehicle, and improving fuel economy and performance.

[0051] It should be noted that the X-direction, Y-direction and Z-direction mentioned in this application all adopt the vehicle body coordinate system, that is, the X-direction generally refers to the front and rear direction of the vehicle travel; the Y-direction refers to the left and right direction of the vehicle, which is perpendicular to the front and rear direction of the vehicle; the Z-direction refers to the up and down direction of the vehicle, that is, the direction perpendicular to the ground and the vehicle plane.

[0052] Furthermore, the outer wall of the crossbeam structure 20 includes a mounting surface A, and the integrated bracket 10 is connected to the mounting surface A. The mounting surface A is usually designed to be a flat surface to ensure the stability and accuracy of the integrated bracket 10. The integrated bracket 10 is used to integrate various devices and components into the crossbeam structure 20, thereby realizing the compactness, efficiency and modularity of the equipment; please refer to the following for details.

[0053] Furthermore, the air supply device 30 includes an air circuit electromagnetic distribution valve assembly 31 and an electronic air pump 32; the air circuit electromagnetic distribution valve assembly 31 and the electronic air pump 32 are connected to the air in the crossbeam structure 20 through the air storage pipe, and the electronic air pump 32 can compress the air and transport it to the air tank through the air storage pipe, and then transport it to the air spring through the air tank to meet the requirements of adjusting the stiffness or vehicle height of the air suspension. Among them, the integrated bracket 10 is provided with a mounting hole group 11, and the mounting hole group 11 includes a plurality of mounting holes located in different directions of the integrated bracket 10. The air circuit electromagnetic distribution valve assembly 31 and the electronic air pump 32 are connected to the integrated bracket 10 from different mounting positions through the mounting holes. This design can provide greater spatial layout flexibility, so that the installation of the gas circuit electromagnetic distribution valve assembly 31 and the electronic air pump 32 can be adjusted according to actual needs and space conditions. For example, the gas circuit electromagnetic distribution valve assembly 31 can be installed on the integrated bracket 10 from the Y direction, and the electronic air pump 32 can be installed on the integrated bracket 10 from the Z direction to achieve the best layout and installation effect; forming a compact module; this design makes installation and maintenance simpler and more efficient.

[0054] like Figures 3 to 7 , Figure 4 It is a schematic structural diagram of the crossbeam structure 20 and the integrated bracket 10 provided in an embodiment of the utility model.

[0055] In a preferred embodiment, the integrated crossbeam assembly 100 also includes an air-conditioning compressor 40, the mounting hole group 11 includes a plurality of compressor mounting holes 111, and the compressor mounting holes 111 are arranged on the side wall of the integrated bracket 10; the air-conditioning compressor 40 is connected to the crossbeam structure 20 along the extension direction of the crossbeam (i.e., the Y direction) through the compressor mounting holes 111.

[0056] Specifically, the air-conditioning compressor 40 is provided with a bolt hole 411, and the bolt hole 411 and the compressor mounting hole 111 match each other. The air-conditioning compressor 40 is supported on the mounting surface A and connected to the integrated bracket 10 through the bolt hole 411 and the compressor mounting hole 111. The bolt hole 411 and the compressor mounting hole 111 match each other, so that the air-conditioning compressor 40 can be firmly connected to the integrated bracket 10 by fasteners such as bolts. The connection method is simple and reliable, and can withstand greater forces and vibrations, ensuring the stability and reliability of the air-conditioning compressor 40 during operation; and by installing the air-conditioning compressor 40 on the beam structure 20 along the Y direction, its height in the Z direction (i.e., the vertical direction) can be significantly reduced. This helps to reduce the height of the entire integrated beam assembly 100 and make more flexible use of the cabin space.

[0057] Furthermore, the mounting hole group 11 includes a plurality of air pump mounting holes 112, and the air pump mounting holes 112 are arranged along the Z direction, and the electronic air pump 32 is mounted on the integrated bracket 10 along the Z direction through the air pump mounting holes 112. Similarly, the electronic air pump 32 can be mounted vertically on the integrated bracket 10, thereby reducing the space occupied in the horizontal direction (such as the X direction or the Y direction); thereby, the electronic air pump 32 can work better with the air conditioning compressor 40, avoiding possible interference or conflict with the air conditioning compressor 40 in the horizontal direction, and further realizing a more compact and efficient overall layout.

[0058] Furthermore, a distribution valve mounting hole 113 is provided at one end of the integrated bracket 10 along the X direction, and the gas circuit electromagnetic distribution valve assembly 31 is connected to the integrated bracket 10 through the distribution valve mounting hole 113; the gas circuit electromagnetic distribution valve assembly 31 can ensure stable installation and fixation of the gas circuit electromagnetic distribution valve assembly by providing a special distribution valve mounting hole 113 on the integrated bracket 10.

[0059] Furthermore, the distribution valve installation hole 113 is arranged along the Z direction; similarly, the gas circuit electromagnetic distribution valve assembly 31 can be vertically installed on the integrated bracket 10. This installation method can more effectively utilize the vertical space and improve the space utilization rate.

[0060] like Figure 5 , Figure 5 (a) is a top view of a partial structure of the integrated beam assembly 100 provided in an embodiment of the present invention. Figure 5 (b) to Figure 5 (d) Figure 5 (a) Cross-sectional views corresponding to AA, BB and CC.

[0061] Furthermore, the integrated cross beam assembly 100 includes a stepped shaft 51 and an air storage pipe 52. The stepped shaft 51 is connected to the cavity structure inside the cross beam structure 20. The air circuit electromagnetic distribution valve assembly 31 is connected to the stepped shaft 51 and the electronic air pump 32 through the air storage pipe 52. The step shaft 51 allows air to flow from the cavity structure inside the cross beam structure 20. Through the stepped shaft 51, air can be drawn from the cross beam structure 20 to the air circuit electromagnetic distribution valve assembly 31. The ECU (Electronic Control Unit) controls the switch of the air circuit electromagnetic distribution valve assembly 31 according to the signal of the vehicle body sensor, thereby distributing the stable high-pressure gas in the cross beam structure 20 to the air suspension, so as to provide a compact and reliable way to manage air flow.

[0062] Continue reading Figure 3 The integrated crossbeam assembly 100 further includes an electronic water pump 60 . A water pump mounting hole 114 is provided at the other end of the integrated bracket 10 along the X direction. The electronic water pump 60 is connected to the integrated bracket 10 through the water pump mounting hole 114 .

[0063] Specifically, the electronic water pump 60 is disposed at one end of the integrated bracket 10 along the X direction and away from the gas circuit electromagnetic distribution valve assembly 31, and the water pump installation hole 114 is disposed on the side wall of the integrated bracket 10 in this direction.

[0064] In a further solution of the present application, the interior of the integrated bracket 10 is hollowed out and provided with a plurality of bracket reinforcing ribs 12 .

[0065] It can be understood that through the internal hollow design, unnecessary materials in the integrated bracket 10 can be removed, the entire integrated bracket 10 can be lightweight, and the overall fuel economy of the vehicle can be improved; the role of the reinforcement rib 12 is to improve its bearing capacity under stress while maintaining the overall structural rigidity of the bracket. The reinforcement rib 12 can effectively disperse stress and prevent the bracket from breaking or deforming.

[0066] like Figure 6 The crossbeam structure 20 includes a crossbeam body 21 and a connector 22; the crossbeam body 21 is a hollow structure with openings B at both ends, and the connector 22 is disposed at two ends of the crossbeam body 21;

[0067] The connecting body 22 includes a connecting plate 221 and a lug plate 222 , wherein the connecting plate 221 is closed at an opening B at the end of the beam body 21 , and the lug plate 222 protrudes from the connecting plate 221 in a direction away from the beam body 21 .

[0068] It can be understood that the hollow structure is the "cavity structure" mentioned above for storing gas, and the connecting body 22 includes a connecting plate 221 and a lug plate 222. The connecting plate 221 can close the opening B at the end of the cross beam body 21 to provide air tightness, and the lug plate 222 protrudes from the connecting plate 221 and extends in a direction away from the cross beam body 21. This design allows the lug plate 222 to be fixed to other components (such as a vehicle body longitudinal beam or a vehicle frame, etc.) by bolts, welding or other connection methods, thereby enhancing the stability and reliability of the cross beam structure 20 in the vehicle.

[0069] Furthermore, at least one beam reinforcement rib 211 is provided inside the beam body 21, which can increase the structural rigidity and help disperse stress, thereby preventing stress from being concentrated in a small area; thereby enhancing the bearing capacity of the beam body 21, reducing the deformation of the beam when subjected to force, maintaining its shape stability, and maintaining the overall structural strength of the integrated beam assembly 100.

[0070] In summary, the integrated crossbeam assembly 100 provided by the embodiment of the utility model is designed to have a sealed cavity structure inside the crossbeam structure 20, which is used to store the high-pressure air required by the air suspension system, ensuring that the air suspension system has a stable air supply. The design also optimizes the spatial layout of the vehicle, reduces the occupation of the trunk space, and improves the space utilization of the vehicle; at the same time, the air supply device 30 is integrated in the crossbeam structure 20 of the vehicle body structure, reducing the risk of explosion caused by damage to the air supply device in a collision accident; this highly integrated design simplifies the assembly steps and improves production efficiency. The integrated crossbeam assembly 100 can be pre-assembled and then assembled on the general assembly line, and then assembled to the vehicle body, thereby improving work efficiency; finally, the entire integrated crossbeam assembly 100 is located at the front of the vehicle, which can reduce the wiring harness layout and is beneficial to the gas distribution and management of the air suspension system.

[0071] like Figure 7 and Fig. 9 The embodiment of the utility model further provides a chassis assembly 200 , including the above-mentioned integrated cross beam assembly 100 ; and further including: a longitudinal beam assembly 201 , the integrated cross beam assembly 100 being connected to the longitudinal beam assembly 201 .

[0072] In a preferred embodiment, a sleeve hole 2221 is provided on the ear plate 222, and the integrated cross beam assembly 100 is connected to the longitudinal beam assembly 201 through the sleeve hole 2221 by an elastic sleeve 330. Specifically, the elastic sleeve is first installed in the sleeve hole 2221. The elastic sleeve 330 includes a rubber shock-absorbing pad 331 and a shock-absorbing pad sleeve 332, which has good buffering and vibration isolation effects, and the corresponding connecting member (such as a convex shaft or pin, bolt, etc.) used to connect the longitudinal beam assembly 201 is aligned with the sleeve hole 2221. Then, the convex shaft or pin is inserted into the sleeve hole so that it passes through the elastic sleeve. When the connecting member is fully inserted into the sleeve hole, the elastic sleeve will tightly wrap the convex shaft or pin to form an elastic fixed connection. This connection allows a certain degree of relative movement, thereby achieving the effect of shock absorption and buffering; the sleeve hole 2221 not only provides an installation position for the elastic sleeve, ensuring the accurate positioning between the integrated cross beam assembly 100 and the longitudinal beam assembly 201; but also the elastic sleeve connection allows a certain elastic deformation at the connection. When the vehicle encounters bumps or vibrations, this elastic connection can absorb part of the impact energy, avoid abnormal noise and structural interference, play a role in blocking vibration, and improve the ride comfort of the vehicle.

[0073] Furthermore, the aluminum alloy profile structure used in the integrated cross beam assembly 100 can significantly reduce the weight of the cross beam assembly, thereby reducing the weight of the entire vehicle, improving fuel economy and performance. It also has the advantages of high strength, good corrosion resistance, and easy processing and forming.

[0074] Those skilled in the art should understand that if all or part of the sub-modules of the integrated beam assembly 100 involved in the various products provided in the embodiments of the present invention are combined and replaced by fusion, simple change, mutual conversion, etc., such as the components are placed and moved; or the products they constitute are set as one piece; or are designed to be detachable; all the combined components can form equipment / devices / systems with specific functions, and using such equipment / devices / systems to replace the corresponding components of the present invention also falls within the protection scope of the present invention.

[0075] Another aspect of the present application provides a vehicle, which includes the above-mentioned chassis assembly 200; obviously, the vehicle has all the advantages brought by the above-mentioned integrated cross beam assembly 100. For example, the design optimizes the spatial layout of the vehicle, reduces the occupation of the trunk space, and improves the space utilization of the vehicle. Of course, the vehicle also has other advantages brought by the above-mentioned front cabin assembly 1000, which will not be repeated here.

[0076] The various technical features described above can be combined arbitrarily. Although all possible combinations of these technical features are not described, any combination of these technical features should be considered to be covered by this specification as long as there is no contradiction in such combination.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
