[0001] The present application relates to the technical field of vehicles, in particular to a front subframe mounting structure and a vehicle. BACKGROUND

[0002] With the improvement of people's living standards and the progress of science and technology, vehicles have gradually become the main means of transportation for people, and people's driving experience of vehicles is also getting higher and higher. Excitation from the road surface and the power assembly is transmitted to the vehicle body through the chassis, suspension and subframe. Among them, the design of the front subframe mounting structure is an important link. The increase of the rigidity of the front subframe mounting structure is beneficial to reduce the energy transmitted to the vehicle body by the subframe and improve the overall comfort.

[0003] The prior art discloses a novel front subframe front mounting plate structure, which comprises a front longitudinal beam front column front plate, a front longitudinal beam front column rear plate, a front subframe front mounting plate and a front subframe front mounting plate reinforcing plate. The mounting plate reinforcing plate is connected with the front subframe front mounting plate to strengthen the rigidity of the front subframe.

[0004] However, the mounting plate reinforcing plate mainly improves the strength of the front subframe front mounting plate connected therewith, and the rigidity in other directions is still poor. CONTENT OF THE UTILITY MODEL

[0005] The purpose of the present application is to provide a front subframe mounting structure and a vehicle, which solves the problem of insufficient rigidity of the existing front subframe mounting structure.

[0006] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0007] On the one hand, the present application provides a front subframe mounting structure, which comprises a subframe mounting plate and a reinforcing plate. The subframe mounting plate comprises a first side plate, a second side plate and a bottom plate, and the second side plate is arranged in a spaced manner with the first side plate. The bottom plate is arranged between the first side plate and the second side plate, and the bottom plate is connected with the first side plate and the second side plate. The reinforcing plate is located between the first side plate and the second side plate, and the reinforcing plate is connected with the first side plate and the second side plate, and the reinforcing plate is arranged in a spaced manner with the bottom plate.

[0008] According to the above technical means, the reinforcing plate is connected with the first side plate and the second side plate of the subframe mounting plate, and is arranged in a spaced manner with the bottom plate of the subframe mounting plate, forming a structure similar to an "I-beam", which makes the subframe mounting structure have good bending stiffness and torsional stiffness. When the vertical load acts on the bottom plate, the force can be transmitted to the reinforcing plate through the first side plate and the second side plate when the bottom plate is subjected to pressure, which can reduce the bending deformation of the bottom plate. The reinforcing plate can also make the vertical load more evenly distributed to the bottom plate, reduce local stress concentration and improve the stability of the overall structure.

[0009] In a possible implementation, the bottom plate is provided with mounting holes, and the number of mounting holes is at least one.

[0010] According to the above technical means, when the front subframe and the subframe mounting plate are installed, there is one or more mounting points between the subframe mounting plate and the front subframe, which improves the stability of the connection between the subframe mounting plate and the front subframe.

[0011] In a possible implementation, the number of mounting holes is two.

[0012] According to the above technical means, when the number of mounting holes is two, the number of mounting points between the front subframe and the subframe mounting plate is two, which can improve the stability between the front subframe and the subframe mounting plate.

[0013] In a possible implementation, the front subframe mounting structure further comprises a sleeve, one end of the sleeve is connected with the bottom plate of the subframe mounting plate, and the other end of the sleeve is connected with the reinforcing plate.

[0014] According to the above technical means, the sleeve can more effectively transmit force to the reinforcing plate, thereby reducing the deformation of the subframe mounting plate. The sleeve can also disperse stress and reduce local stress peaks, further improving the stability of the structure. The sleeve can also provide additional support to prevent the bottom plate from deforming or sagging locally under stress. The sleeve can further strengthen the rigidity of the front subframe mounting structure in the Z direction. The sleeve can also reduce the transmission of vibrations, especially vibrations from the road, and the rigid connection of the sleeve can absorb and isolate part of the vibrations. And reduce the resonance of the structure, reduce the noise caused by the vibration of the structure, thereby improving the NVH performance of the vehicle and improving the comfort of the passengers.

[0015] In a possible implementation, the sleeve is welded to the subframe mounting plate, and the sleeve is welded to the reinforcing plate.

[0016] According to the above technical means, the sleeve is welded to the subframe mounting plate and the reinforcing plate, which is stable and reliable.

[0017] In a possible implementation, the sleeve is a hollow cylindrical structure, and the inner wall of the sleeve is provided with threads.

[0018] According to the above technical means, when the subframe mounting plate and the front subframe are installed, only bolts can be used to complete the connection and fixation between the front subframe and the subframe mounting plate. For example, a bolt can be used to pass through the front subframe, then pass through the bottom plate of the subframe mounting plate through the mounting hole, extend into the hollow structure of the sleeve, and be connected with the inner wall of the sleeve through threads, without the need for additional nuts for connection and fixation, thereby simplifying the installation.

[0019] In a possible implementation, the reinforcing plate comprises a reinforcing plate bottom plate and a reinforcing plate side plate, wherein the reinforcing plate side plate is arranged around the reinforcing plate bottom plate, and the reinforcing plate side plate is connected to the reinforcing plate bottom plate. The reinforcing plate side plate is connected to the first side plate, and the reinforcing plate side plate is connected to the second side plate.

[0020] According to the technical means, the structural rigidity of the reinforcing plate can be enhanced.

[0021] In a possible implementation, the reinforcing plate side plate is provided with a reinforcing portion.

[0022] According to the technical means, the reinforcing portion can further enhance the structural rigidity of the reinforcing plate side plate, thereby improving the overall rigidity of the reinforcing plate.

[0023] In a possible implementation, the reinforcing plate bottom plate and the reinforcing plate side plate are integrally formed.

[0024] According to the technical means, the integrally formed reinforcing plate bottom plate and reinforcing plate side plate are more conducive to improving the rigidity of the reinforcing plate.

[0025] In another aspect, the embodiments of the present application provide a vehicle comprising the front subframe mounting structure in the above aspect.

[0026] Since the vehicle provided by the embodiments of the present application comprises any one of the front subframe mounting structures in the above aspect, the same technical problems as the above front subframe mounting structures can be solved, and the same technical effects can be achieved, which will not be described here.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0044] The embodiments of the present application provide a vehicle.

Meanwhile, the vehicle provided by the embodiments of the present application can also be a vehicle in different forms. For example, the vehicle provided by the embodiments of the present application can be a sedan, a sport utility vehicle (SUV) or a multi-Purpose Vehicles (MPV).

[0045] The vehicle can include a vehicle frame. The vehicle frame can form the overall shape configuration of the outside of the vehicle and form a passenger space for accommodating passengers. The vehicle frame is formed with a door structure through which a user can enter and exit.

[0046] In addition, in order to realize the driving of the vehicle, the vehicle can further include an electric drive system assembly. The electric drive system assembly can include an electric drive system. The electric drive system can include a drive motor and a reducer. The drive motor can provide power, and the reducer can be connected with the drive motor. The reducer can adjust the rotating speed to enable the vehicle to run at different speeds. According to different driving modes of the electric drive system, the electric drive system can be divided into front drive, rear drive and four-wheel drive arrangements.

[0047] In addition, the vehicle can further include a transmission system, which can be connected with the electric drive system and can transmit the power generated by the engine to the wheels.

[0048] In order to supply power to the electric components such as the drive motor, the vehicle provided by the embodiments of the present application further includes a battery system. The battery system can include a battery pack, which can be used to provide electric energy. The battery pack can be connected with the electric drive system and other electrical components of the vehicle. In this way, the electric energy of the battery pack can be transmitted to each component of the vehicle for power supply.

[0049] In addition, the vehicle provided by the embodiments of the present application can further include a front subframe mounting structure. The front subframe is an important component connecting the wheel system and the vehicle body, and undertakes the task of supporting the power assembly components such as the engine, the transmission and the suspension system. The front subframe mounting structure provided by the present application undertakes the installation and connection function, and the front subframe is firmly connected with the vehicle body through the front subframe mounting structure, thereby ensuring the stable installation of the power assembly and the suspension system.

[0050] The road surface and power assembly excitation is transmitted to the vehicle body through the chassis, suspension and subframe. In order to meet the customer's driving experience and feeling, the vehicle comfort is improved. The design of the front subframe mounting structure is an important link. The main control index of the front subframe mounting structure is its dynamic stiffness. By improving the dynamic stiffness, the energy transmitted to the vehicle body by the subframe can be reduced, and the vehicle comfort is improved.

[0051] As shown in Figure 1 , the front subframe mounting structure provided by the application mainly comprises a subframe mounting plate 1. The subframe mounting plate 1 comprises a first side plate 11 and a second side plate 12, and the first side plate 11 and the second side plate 12 are arranged at intervals. The subframe mounting plate 1 further comprises a bottom plate 13 arranged between the first side plate 11 and the second side plate 12, and the bottom plate 13 is connected with the first side plate 11, and the bottom plate 13 is also connected with the second side plate 12. The subframe mounting plate 1 is mainly used for connecting with the front subframe and providing a mounting and fixing position for the front subframe.

[0052] On this basis, as shown in Figure 2 , the front subframe mounting structure provided by the application further comprises a reinforcing plate 2, as shown in Figure 3 , the reinforcing plate 2 is located between the first side plate 11 and the second side plate 12, and the reinforcing plate 2 is connected with the first side plate 11 and the second side plate 12. And the reinforcing plate 2 is arranged at intervals with the bottom plate 13.

[0053] In this way, the reinforcing plate 2 is connected with the first side plate 11 and the second side plate 12 of the subframe mounting plate 1, and is arranged at intervals with the bottom plate 13 of the subframe mounting plate 1, forming a structure similar to a "I-beam", which makes the subframe mounting structure have good bending stiffness and torsional stiffness. When the vertical load acts on the bottom plate 13, the bottom plate 13 is subjected to pressure, and the force can be transmitted to the reinforcing plate 2 through the first side plate 11 and the second side plate 12, which can reduce the bending deformation of the bottom plate 13. The reinforcing plate 2 can also make the vertical load more evenly distributed to the bottom plate 13, reduce local stress concentration, and improve the stability of the overall structure.

[0054] In addition, the reinforcing plate 2 is arranged at intervals with the bottom plate 13, and the interval therebetween can provide a certain elasticity, which is helpful to absorb and reduce vibration, and is conducive to improving the NVH performance and improving the vehicle comfort.

[0055] On this basis, as shown in Figure 4As shown, the front subframe mounting structure 100 provided by the present application further comprises a front beam plate 101, a U-shaped beam inner plate 102, a beam outer plate 103, and a cabin beam connecting piece 104. The front beam plate 101, the U-shaped beam inner plate 102, the beam outer plate 103, the cabin beam connecting piece 104, and the above-mentioned subframe mounting plate 1 and the reinforcing plate 2 form a closed cavity. The stiffness and dynamic stiffness of the front subframe mounting structure 100 in three directions are improved, and the vibration energy is effectively reduced to the vehicle body.

[0056] As shown in the figure, Figure 5 The front beam plate 101 and the U-shaped beam inner plate 102 are connected by four two-layer welds, as shown by the welding points 1001.

[0057] The reinforcing plate 2 and the subframe mounting plate 1 are connected by three two-layer welds on the left and right, as shown by the welding points 1002( Figure 3 ).

[0058] As shown in the figure, Figure 6 The cabin beam connecting piece 104 and the reinforcing plate 2 are connected by two two-layer welds, as shown by the welding points 1003. The left, right, and lower sides of the cabin beam connecting piece 104 and the subframe mounting plate 1 are connected by six two-layer welds, of which the left, right, and lower sides are connected by two two-layer welds, as shown by the welding points 1004.

[0059] As shown in the figure, Figure 7 The first side plate 11 of the subframe mounting plate 1 and the side of the U-shaped beam inner plate 102 are connected by three two-layer welds, as shown by the welding points 1005. The front beam plate 101, the U-shaped beam inner plate 102, and the subframe mounting plate 1 are connected by one three-layer weld, as shown by the welding points 1006. In addition, the subframe mounting plate 1 and the front beam plate 101 are connected by four two-layer welds, as shown by the welding points 1007.

[0060] In order to realize the connection between the first side plate 11 of the subframe mounting plate 1 and the U-shaped beam inner plate 102, the first side plate 11 of the subframe mounting plate 1 has a first flange 110( Figure 1 ) which is bent in a direction away from the second side plate 12. The subframe mounting plate 1 is connected to the U-shaped beam inner plate 102 through the first flange 110.

[0061] As shown in the figure, Figure 8 The second side plate 12 of the subframe mounting plate 1 and the front beam plate 101 are connected by two two-layer welds, as shown by the welding points 1008. The second side plate 12 of the subframe mounting plate 1 has a second flange 120( Figure 1 ) which is bent in a direction away from the first side plate 11. The subframe mounting plate 1 is connected to the front beam plate 101 through the second flange 120.

[0062] See also Figure 9 The U-shaped longitudinal beam inner plate 102 and the cabin side beam connector 104 are connected by two two-layer welding, see welding point 1009.

[0063] like Figure 10 As shown, the outer plate 103 of the longitudinal beam and the front sealing plate 101 of the longitudinal beam are connected by two double-layer welds, as shown at welding point 1010. The outer plate 103 of the longitudinal beam and the upper flange of the inner plate 102 of the U-shaped longitudinal beam are connected by three double-layer welds, as shown at welding point 1011. The outer plate 103 of the longitudinal beam, the lower flange of the inner plate 102 of the U-shaped longitudinal beam, and the subframe mounting plate 1 are connected by two triple-layer welds, as shown at welding point 1012.

[0064] In summary, the front subframe mounting structure 100 provided in this application mainly includes a longitudinal beam front end plate 101, a U-shaped longitudinal beam inner plate 102, a longitudinal beam outer plate 103, an engine compartment side beam connector 104, and a subframe mounting plate 1 and a reinforcing plate 2. The longitudinal beam front end plate 101, the U-shaped longitudinal beam inner plate 102, the longitudinal beam outer plate 103, the engine compartment side beam connector 104, and the subframe mounting plate 1 and the reinforcing plate 2 are connected by two-layer or three-layer welding, forming a closed cavity between the longitudinal beam front end plate 101, the U-shaped longitudinal beam inner plate 102, the longitudinal beam outer plate 103, the engine compartment side beam connector 104, and the subframe mounting plate 1 and the reinforcing plate 2, with the reinforcing plate 2 located within this closed cavity. This improves the overall rigidity and dynamic rigidity of the subframe mounting structure 100 provided in this application and effectively reduces the transmission of vibration energy to the vehicle body through the subframe mounting plate 1, thus improving the overall vehicle comfort.

[0065] The base plate 13 of the subframe mounting plate 1 is provided with mounting holes 130. Figure 1 ), and the number of mounting holes 130 is at least one.

[0066] In this way, when the front subframe is installed with the subframe mounting plate 1, there are one or more mounting points between the subframe mounting plate 1 and the front subframe, which improves the stability of the connection between the subframe mounting plate 1 and the front subframe.

[0067] Furthermore, it should be noted that the installation between the front subframe and the subframe mounting plate 1 is typically achieved using threaded fasteners. For example, bolts are passed through the mounting holes 130 on the front subframe and the subframe mounting plate 1, and nuts are threaded onto the bolts to achieve the connection and fixation between the front subframe and the subframe mounting plate 1.

[0068] In some embodiments of this application, such as Figure 1 As shown, the number of mounting holes 130 provided on the subframe mounting plate 1 can be two, that is, there are two mounting points between the front subframe and the subframe mounting plate 1. This is to improve the stability of the connection between the front subframe and the frame mounting plate 1.

[0069] In some embodiments of the present application, as shown in Figure 3 The front subframe mounting structure 100 provided by the present application further comprises a sleeve 3, one end of the sleeve 3 is connected with the bottom plate 13 of the subframe mounting plate 1, and the other end of the sleeve 3 is connected with the reinforcing plate 2.

[0070] As shown in Figure 11 The sleeve 3 and the subframe mounting plate 1 are connected by seam welding.

[0071] In this way, the sleeve 3 can more effectively transmit the force to the reinforcing plate 2, thereby reducing the deformation of the subframe mounting plate 1. The sleeve 3 can also disperse stress and reduce local stress peaks, further improving the stability of the structure. The sleeve 3 can also provide additional support to prevent the bottom plate 13 from deforming or sagging locally when subjected to force. The sleeve 3 can further strengthen the rigidity of the front subframe mounting structure 100 in the Z direction.

[0072] The sleeve 3 can also reduce the transmission of vibrations, especially vibrations from the road, and the rigid connection of the sleeve 3 can absorb and isolate part of the vibrations. In addition, the sleeve 3 can reduce the resonance of the structure and reduce the noise caused by structural vibrations, thereby improving the NVH performance of the vehicle and improving the comfort of the passengers.

[0073] In addition, it should be noted that the sleeve 3 and the subframe mounting plate 1 are connected by welding, and the sleeve 3 and the reinforcing plate 2 are connected by welding.

[0074] In this way, the sleeve 3 is connected with the subframe mounting plate 1 and the reinforcing plate 2 by welding, which is more reliable.

[0075] In some embodiments of the present application, the sleeve 3 can be a hollow cylindrical structure, and the inner wall of the sleeve 3 is provided with threads. In this case, the hollow part of the sleeve 3 can be in communication with the mounting hole 130 on the bottom plate 13.

[0076] In this way, when the subframe mounting plate 1 is connected with the front subframe, only bolts can be used to complete the connection and fixation between the front subframe and the subframe mounting plate 1. For example, a bolt can be used to pass through the front subframe, then pass through the bottom plate 13 of the subframe mounting plate 1 through the mounting hole 130, and extend into the hollow structure of the sleeve 3 and be connected with the inner wall of the sleeve 3 by threads, without the need for further connection and fixation by nuts, thereby simplifying the installation.

[0077] Next, the structure of the reinforcing plate 2 provided by the present application will be further described in conjunction with the drawings. The reinforcing plate 2 comprises a reinforcing plate bottom plate 21 and a reinforcing plate side plate 22 Figure 2The reinforcing plate side plate 22 is arranged around the reinforcing plate bottom plate 21, and the reinforcing plate side plate 22 is connected with the reinforcing plate bottom plate 21. The reinforcing plate side plate 22 is connected with the first side plate 11 of the sub-frame mounting plate 1, and the reinforcing plate side plate 22 is also connected with the second side plate 12 of the sub-frame mounting plate 1. That is, the reinforcing plate 2 is connected with the sub-frame mounting plate 1 through the reinforcing plate side plate 22.

[0078] As known from the above, the reinforcing plate 2 comprises the reinforcing plate bottom plate 21 and the reinforcing plate side plate 22, and the reinforcing plate side plate 22 is arranged around the reinforcing plate bottom plate 21, so that the overall structural strength of the reinforcing plate 2 can be enhanced.

[0079] The reinforcing plate side plate 22 and the sub-frame mounting plate 1 can be connected by welding, for example, the reinforcing plate side plate 22 and the sub-frame mounting plate 1 can be connected by two layers of welding. Alternatively, the reinforcing plate side plate 22 and the sub-frame mounting plate 1 can also be connected by using a threaded connecting piece, for example, a bolt is used to penetrate the reinforcing plate side plate 22 and the sub-frame mounting plate 1, and then a nut is used to threadedly connect with the bolt, so as to fix the reinforcing plate side plate 22 and the sub-frame mounting plate 1 together.

[0080] On this basis, in order to further enhance the structural strength of the reinforcing plate 2, as shown in Figure 2 The reinforcing plate side plate 22 is provided with a reinforcing portion 220.

[0081] Based on this, the number of the reinforcing portion 220 can be multiple, and the multiple reinforcing portions 220 are arranged on the reinforcing plate side plate 22 in an interval. The reinforcing portion 220 can be integrally formed by stamping, or integrally formed by casting, or the reinforcing portion 220 can also be integrally connected with the reinforcing plate side plate 22 by welding. Further, the reinforcing portion 220 can be a reinforcing rib which is recessed towards the inside of the reinforcing plate side plate 22.

[0082] In addition, it should be noted that the reinforcing plate bottom plate 21 and the reinforcing plate side plate 22 are integrally formed, for example, by stamping process or casting process.

[0083] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
