Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automobile structure design, and in particular relates to a front engine compartment module and a vehicle. BACKGROUND

[0002] In the current automobile manufacturing industry, the front engine compartment assembly, as an important component of the automobile, undertakes the key task of supporting the engine, transmission system and other key components. The structural design and material selection of this component have a crucial impact on the overall performance, safety and lightweight level of the automobile.

[0003] Currently, there are mainly two technical structures of the front engine compartment assembly: one is a front engine compartment assembly manufactured by sheet metal welding process, and the other is an integrated die-casting front engine compartment assembly. Although these two structures have been widely used in automobile manufacturing, they both have some inherent problems.

[0004] Firstly, for the front engine compartment assembly made of sheet metal welding, its structure is usually composed of multiple sheet metal parts connected by complex welding process. Although this structure has high strength and rigidity, due to the limitations of welding process and the connection requirements of multiple components, the overall structure is relatively complex, which causes material redundancy and excessive weight. This not only increases the manufacturing cost of the automobile, but also affects the fuel economy and lightweight level of the automobile. Secondly, for the integrated die-casting front engine compartment assembly, although it integrates multiple components into one whole through die-casting process, thereby reducing the number and complexity of connecting parts, the overall weight is still large. Although the die-casting process can improve the material utilization and the integrity of the structure, due to the limitations of the size and shape of the die-casting parts, as well as the defects and residual stress that may be generated during the die-casting process, this structure still has certain limitations in lightweight.

[0005] In addition, whether it is a front engine compartment assembly made of sheet metal welding or an integrated die-casting front engine compartment assembly, they are independently arranged with the chassis front subframe and connected through fasteners such as bolts. Although this connection method has certain reliability and detachability, it also leads to structural redundancy and further increases the weight. CONTENT OF THE UTILITY MODEL

[0035] like Figures 2 to 6 As shown, a front cabin module 100 provided in an embodiment of the present application includes an integrated die-cast cabin 10 and a suspension system 20; based on the general concept of the present application, the integrated die-cast cabin 10 includes a transverse main beam 11 and two symmetrical supporting components 12 respectively arranged at the ends of the main cross beam 11, each supporting component 12 includes a longitudinal beam 121; the suspension systems 20 are two in number and are symmetrically arranged.

[0036] Each of the brake knuckle assembly 21 is assembled with a corresponding receiving assembly 12, while the upper control arm 22 and the lower control arm 23 are connected to the same longitudinal beam 121. This connection not only simplifies the structure, but also reduces the number of connection points, thereby improving the overall reliability and durability. And it is equivalent to integrating the subframe into the front engine compartment module to provide connection points, achieving a highly integrated design; not only reduces the number of parts and assembly time, but also improves the stability and reliability of the entire system. At the same time, by optimizing the connection method, reducing the number of connection points, reducing manufacturing difficulty and cost, and improving the overall structure and strength of the structure. The integrated design makes the front engine compartment module more compact and lightweight, which helps to improve the handling performance and fuel economy of the vehicle, and the entire integrated die-casting engine compartment 10 can be manufactured by an integrated die-casting process, reducing material waste.

[0037] It can be understood that the transverse main beam 11 serves as the main structural support of the engine compartment and is arranged transversely along the Y direction, and the transverse main beam 11 ensures the strength and stability of the entire front engine compartment module; the receiving assemblies 12 are arranged at both ends of the transverse main beam 11 and are symmetrically distributed; each receiving assembly 12 includes a longitudinal beam 121 to provide a stable connection point for the suspension system and optimize the stress distribution of the overall structure.

[0038] The front engine compartment module 100 includes two symmetrically arranged suspension systems 20, each of which is composed of a brake knuckle assembly 21, an upper control arm 22, and a lower control arm 23; through mutual cooperation, it provides the necessary suspension and damping functions for the wheels, while ensuring that the wheels can smoothly contact the ground.

[0039] Each of the brake knuckle assembly 21 is assembled with a corresponding receiving assembly 12, while the upper control arm 22 and the lower control arm 23 are connected to the same longitudinal beam 121. This connection not only simplifies the structure, but also reduces the number of connection points, thereby improving the overall reliability and durability. And it is equivalent to integrating the subframe into the front engine compartment module to provide connection points, achieving a highly integrated design; not only reduces the number of parts and assembly time, but also improves the stability and reliability of the entire system. At the same time, by optimizing the connection method, reducing the number of connection points, reducing manufacturing difficulty and cost, and improving the overall structure and strength of the structure. The integrated design makes the front engine compartment module more compact and lightweight, which helps to improve the handling performance and fuel economy of the vehicle, and the entire integrated die-casting engine compartment 10 can be manufactured by an integrated die-casting process, reducing material waste.

[0040] The suspension system 20 further includes a shock absorber 24; the receiving assembly 12 further includes a front wheel cover 122 arranged on the longitudinal beam 121, and the front wheel cover 122 is provided with a shock absorber mounting seat T penetrating through the front wheel cover 122; the shock absorber 24 is mounted at the shock absorber mounting seat T.

[0041] The front wheel cover 122 is added to the longitudinal beam 121 to enhance the overall strength of the receiving assembly 12 and provide space for the installation of the shock absorber; the shock absorber mounting seat T is arranged through the structure of the front wheel cover 122. A stable mounting position is provided for the shock absorber 24, ensuring the installation strength of the shock absorber 24 and effectively playing its damping role.

[0042] The edge of the front wheel cover 122 is connected with a longitudinal arm 123, and the longitudinal beam 121 is provided with a box-shaped body 121a with a cavity inside at one end along the x direction; wherein the longitudinal beam 121 comprises two first mounting brackets a1 protruding from the front wheel cover 122, and the first mounting brackets a1 are spaced along the x direction respectively; correspondingly, the upper control arm 22 comprises a first front end r1 and a first rear end r2, and the first front end r1 and the first rear end r2 are connected to the corresponding first mounting brackets a1 respectively.

[0043] The front wheel cover 122 is the main part of the receiving assembly 12, which not only provides the function of protecting the internal mechanical components but also serves as the basis for connecting other components; the longitudinal arm 123 is connected at the edge of the front wheel cover 122, which structurally enhances the strength and stability of the receiving assembly 12; it bears the longitudinal force from the suspension system and ensures the stability of the entire front cabin module; the longitudinal beam 121 is provided with a box-shaped body 121a with a cavity inside at one end along the x direction, which can provide a mounting structure for the front crash beam energy absorption box.

[0044] Further, the first mounting brackets a1 are arranged on the side of the longitudinal arm 123 facing the longitudinal beam 121 and are spaced along the x direction (the front-rear direction of the vehicle). The two brackets protrude from the front wheel cover 122 and provide a stable connection point for the upper control arm 22 of the suspension system. The upper control arm 22 comprises a first front end r1 and a first rear end r2, and the two ends are connected to the corresponding two first mounting brackets a1 respectively. This connection mode ensures that the suspension system can be stably connected to the receiving assembly, thereby realizing the suspension function of the vehicle.

[0045] The side of the box-shaped body 121a away from the front wheel cover 122 is provided with two second mounting brackets a2 spaced along the x direction and protruding from the box-shaped body 121a, and the lower control arm 23 comprises a second front end u1 and a second rear end u2, and the second front end u1 and the second rear end u2 are connected to the corresponding second mounting brackets a2 respectively.

[0046] The box-shaped body 121a is designed as a cavity inside the longitudinal beam 121, which aims to reduce weight while maintaining the strength and rigidity of the structure. This design not only optimizes the utilization of materials, but also improves the overall performance of the front cabin module 100. The second mounting brackets a2 are arranged on the side of the box-shaped body 121a away from the front wheel cover 122, and two second mounting brackets a2 are spaced along the x direction (i.e. the front-rear direction of the vehicle) and protrude from the box-shaped body 121a; the two brackets provide a stable connection point for the lower control arm 23, ensuring that the suspension system can be correctly connected to the receiving assembly 12.

[0047] The lower control arm 23 is responsible for connecting the wheels and the vehicle body, and bearing various forces and vibrations from the road, including the second front end u1 and the second rear end u2 connected to the corresponding two second mounting brackets a2 respectively; through precise design and manufacturing, the second front end u1 and the second rear end u2 of the lower control arm 23 can be closely connected to the second mounting bracket a2, thereby forming a stable and reliable suspension system.

[0048] The purpose of directly connecting the upper and lower control arms of the suspension system 20 to the longitudinal beam 121 of the receiving assembly 12 is to omit the traditional front subframe structure, thereby achieving high integration of the front engine compartment module; simplifying the assembly process of the vehicle and improving production efficiency; the protruding design of the second mounting bracket a2 and the close connection with the box-shaped body 121a ensure the stable connection between the suspension system and the receiving assembly; improve the handling stability and ride comfort of the vehicle; and the cavity design of the box-shaped body 121a not only reduces the weight, but also improves the strength and rigidity of the structure, which helps to reduce the fuel consumption of the vehicle and improve the fuel economy.

[0049] In a further aspect of the application, the longitudinal arm 123 includes a plurality of first reinforcing ribs t1 arranged at intervals, and the box-shaped body 121a includes a plurality of second reinforcing ribs t2. The first reinforcing ribs t1 serve to enhance the strength and rigidity of the longitudinal arm, enabling it to better withstand longitudinal forces from the suspension system. By optimizing the layout and number of reinforcing ribs, the front wheel cover 122 can be ensured not to deform or break under heavy load, thereby improving the stability of the entire front engine compartment module; the second reinforcing ribs t2: a plurality of second reinforcing ribs t2 are also arranged inside the longitudinal beam 121; the reinforcing ribs not only enhance the strength and rigidity of the box-shaped body 121a, but also optimize its internal structure and improve the utilization of materials. By arranging the reinforcing ribs reasonably, the vibration and impact force from the road can be effectively resisted, ensuring that the vehicle can maintain a smooth driving state under various road conditions.

[0050] The box-shaped body 121a is provided with a drive shaft through hole H penetrating along the y direction, which mainly allows the drive shaft 25 to pass through and realize the rotary connection between the drive shaft and the box-shaped body; the suspension system 20 further includes a drive shaft 25; the drive shaft 25 is responsible for transmitting power from the engine to the wheels, while allowing the wheels to jump up and down under the support of the suspension system. The drive shaft 25 passes through the drive shaft through hole H on the box-shaped body 121a and realizes rotary connection with the through hole, which can not only ensure the transmission of power, but also ensure that the suspension function of the wheels is not affected; by providing the drive shaft through hole H on the box-shaped body 121a, the direct connection between the drive shaft 25 and the suspension system is realized, without the need for additional brackets or connecting parts, making the structure more compact and efficient.

[0051] In the embodiments of the present application, the integrated die-casting cabin 10 further comprises a torsion box structure 13 arranged at the connection between the transverse main body beam 11 and the receiving assembly 12, thereby improving the overall strength and rigidity of the cabin structure. This design enables the cabin to better withstand various forces and vibrations from the suspension system and the vehicle body. In the event of a collision, the torsion box structure 13 can absorb the impact force from the impact direction and disperse it to the surrounding structural components. This helps to reduce the damage to the overall structure of the vehicle during a collision, thereby improving the durability and safety of the vehicle.

[0052] The side of the front wheel cover 122 facing away from the longitudinal beam 121 is provided with a plurality of reinforcing ribs t3, which are partially connected to the side wall of the front wheel cover 122 and / or the longitudinal beam 121 and partially connected to the shock absorber mounting seat T. This ensures that the reinforcing ribs can effectively connect the front wheel cover, the longitudinal beam, and the shock absorber mounting seat into a whole, forming a more stable structure, enhancing the strength and rigidity of the front wheel cover, and preventing it from deforming or breaking when subjected to external forces.

[0053] The longitudinal arm 123 is provided with a flange structure b at both ends along the x direction; one is to enhance the strength of the end of the longitudinal arm: as the longitudinal arm endures and transmits forces, its end often bears a lot of stress and deformation, so by adding a flange structure, the rigidity and durability of the end can be effectively improved, preventing it from breaking or deforming during long-term use. At the same time, the flange structure b facilitates welding of the longitudinal arm with other elements. Since the flange structure increases the surface area of the end of the longitudinal arm, it can be more easily welded to other components (such as the vehicle body, suspension bracket, etc.), which is not only firm and reliable, but also improves production efficiency and reduces manufacturing costs.

[0054] Further, those skilled in the art should understand that if all or part of the sub-modules involved in the products of the front cabin module 100 provided by the embodiments of the present application are combined, replaced, transformed, etc. by means of fusion, simple change, mutual transformation, etc., such as moving the position of each component; or integrally arranging the products formed thereby; or detachable design; as long as the combined components can form a device / apparatus / system with a specific function, using such device / apparatus / system to replace the corresponding components of the present application also falls within the protection scope of the present application.

[0055] The second aspect of the present application also provides an automobile comprising the above-mentioned front cabin module 100.

[0056] The technical features described above can be combined in any way. Although not all possible combinations of these technical features are described, any combination of these technical features should be considered to be covered by the present specification, as long as such a combination does not contradict.

[0057] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still adjust the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these adjustments or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
