Description

[0001] The utility model relates to the technical field of automobiles, and specifically provides a subframe mounting bracket and a vehicle. Background Art

[0002] With the rapid development of electric vehicle technology, rear-mounted motors have become a mainstream layout solution, demonstrating significant advantages in improving vehicle performance and optimizing interior space layout. In this layout, the motor is generally integrated into the rear subframe, which is then mounted on the longitudinal beam of the vehicle body. Compared to traditional fuel vehicles, the rear-mounted motor layout will increase the rear overhang weight of the vehicle body, resulting in greater stress on the mounting points of the rear subframe and the longitudinal beam. However, due to the limitations of the internal space and manufacturing process of the longitudinal beam, the existing technology generally uses threaded tubes to fasten the corresponding components on the rear subframe and the longitudinal beam respectively. However, this connection structure can only meet basic strength requirements, resulting in low strength at the mounting points of the subframe and the longitudinal beam, which can easily lead to durability issues such as deformation and cracking at the mounting points of the subframe and the longitudinal beam, thereby affecting the driving safety of the vehicle.

[0003] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0014] In a second aspect, the present invention further provides a vehicle, comprising the above-mentioned subframe mounting bracket.

[0015] As will be understood by those skilled in the art, the technical solution of the present invention provides a subframe mounting bracket, comprising a longitudinal beam, a mounting post, and a reinforcement member. The longitudinal beam is provided with a mounting hole and a cavity. The mounting post is connected to the mounting hole. The first end of the mounting post extends through the mounting hole into the cavity. The second end of the mounting post is connected to the subframe. The reinforcement member is disposed at the connection between the mounting post and the mounting hole, and the reinforcement member is welded to the mounting post and the inner wall of the cavity. By adopting the above technical solution, the present invention can improve the connection strength and rigidity of the connection between the mounting post and the longitudinal beam, thereby effectively preventing deformation and cracking at the connection between the mounting post and the longitudinal beam, achieving an efficient and stable connection between the mounting post and the longitudinal beam, and providing strong protection for the installation and use of the subframe. Specifically, the mounting column is designed as a two-section structure. The first end passes through the mounting hole and extends deep into the cavity of the longitudinal beam, thereby increasing the contact area between the mounting column and the longitudinal beam, thereby effectively dispersing stress and reducing local stress concentration; the reinforcing member is arranged at the connection between the mounting column and the mounting hole, and is tightly connected to the mounting column and the inner wall of the cavity by welding, thereby greatly improving the strength and rigidity of the connection, effectively preventing deformation, cracking and other problems of the mounting point caused by uneven force or overload, thereby improving the stability and durability of the entire mounting point structure.

The first reinforcing member is arranged along the axial direction of the mounting column and welded to the mounting column, and the second reinforcing member is arranged along the radial direction of the mounting column and welded to the mounting column. Through this arrangement, the first reinforcing member can directly enhance the bearing capacity and stability of the mounting column in the axial direction (i.e., the length direction), and the second reinforcing member can enhance the stability of the mounting column in the transverse direction (i.e., perpendicular to the length direction), preventing the connection between the mounting column and the mounting hole from being twisted or broken due to lateral force or torque. Thus, the first reinforcing member and the second reinforcing member respectively reinforce the connection between the mounting column and the mounting hole in the axial and radial dimensions, forming an all-round support structure. This multi-dimensional reinforcement method enables the structure at the mounting point to maintain high stability and bearing capacity under various stress conditions.

[0017] Furthermore, the first reinforcement member of the present invention is a first reinforcement plate. The surface of the first reinforcement plate is provided with a strip groove extending along the axial direction of the mounting post. A portion of the mounting post is located within the strip groove and is in contact with the inner wall of the strip groove. The mounting post is welded to the inner wall of the strip groove. Through this arrangement, the strip groove provides a precise positioning reference for the mounting post, allowing the mounting post to maintain the correct position and angle during installation, avoiding problems such as loose connection or uneven force due to installation deviation. The inner wall of the groove is in close contact with the outer surface of the mounting post, increasing the contact area between the two, thereby dispersing stress when subjected to force, reducing local stress concentration, and further improving the load-bearing capacity and stability of the connection.

[0018] Furthermore, the second reinforcement member of the present invention is a second reinforcement plate with a slot formed on its edge. A portion of the mounting post is positioned within the slot and abuts against the inner wall of the slot. The mounting post is then welded to the inner wall of the slot. This arrangement creates a tighter and more reliable connection between the mounting post and the second reinforcement plate, further improving the strength and rigidity of the connection. It also helps optimize stress distribution within the mounting post and its surrounding structure, reducing local stress peaks and thereby extending the service life of the connection structure.

[0029] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are intended solely to illustrate the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the following embodiments are described in conjunction with a vehicle subframe mounting bracket, the subframe mounting bracket provided by the present invention is equally applicable to other products that require solutions to structural joints prone to deformation and cracking.

[0030] It should be noted that, in the description of this utility model, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] Based on the low strength of the mounting points between the rear subframe and the longitudinal beam of existing vehicles as pointed out in the background art, which can easily lead to deformation and cracking at the mounting points, the utility model provides a subframe mounting bracket. The purpose is to improve the connection strength and rigidity of the mounting post and the longitudinal beam connection by providing a reinforcement member at the mounting point between the rear subframe and the longitudinal beam, thereby effectively solving the problem of deformation and cracking at the mounting post and the longitudinal beam connection.

[0032] First refer to Figure 1 ,in, Figure 1 It is an exploded view of the subframe mounting bracket of the present utility model.

[0033] like Figure 1 As shown, the utility model provides a subframe mounting bracket, including a longitudinal beam 1, a mounting column 2 and a reinforcing member. The longitudinal beam 1 is provided with a mounting hole 11 and a cavity 12. The mounting column 2 is connected to the mounting hole 11. The first end of the mounting column 2 passes through the mounting hole 11 and extends into the cavity 12. The second end of the mounting column 2 is connected to the subframe. The reinforcing member is arranged at the connection between the mounting column 2 and the mounting hole 11, and the reinforcing member is welded to the mounting column 2 and the inner wall of the cavity 12.

[0034] As the main body of the mounting bracket, longitudinal beam 1 not only bears the primary load but also, through its mounting holes 11 and cavity 12, allows for precise positioning and securing of mounting post 2. Mounting hole 11 is used for connection to mounting post 2, while cavity 12 provides space for insertion of mounting post 2, increasing the length of the connection and improving its stability. Mounting post 2 is designed as a two-stage structure. The first end extends through mounting hole 11 into cavity 12 of longitudinal beam 1, increasing the contact area between mounting post 2 and longitudinal beam 1. This effectively disperses stress and reduces localized stress concentration. The second end is directly connected to the subframe, acting as a bridge between the subframe and longitudinal beam 1, transmitting and withstanding various forces and moments. The reinforcing member is arranged at the connection between the mounting column 2 and the mounting hole 11, that is, at the mounting point of the mounting column 2, and is tightly connected to the mounting column 2 and the inner wall of the cavity 12 by welding. This can significantly improve the connection strength between the mounting column 2 and the longitudinal beam 1, making the installation of the subframe more stable and reliable; it can also improve the strength of the connection, reduce the deformation and displacement of the mounting column 2 due to vibration or impact, and effectively prevent the deformation, cracking and other problems of the mounting point caused by uneven force or overload, thereby improving the stability and durability of the entire mounting point structure and ensuring the normal operation of the subframe.

[0035] Preferably, if Figure 1 As shown, the reinforcing member includes a first reinforcing member 3 and a second reinforcing member 4. The first reinforcing member 3 and the second reinforcing member 4 are respectively arranged on both sides of the mounting column 2. The first reinforcing member 3 is arranged along the axial direction of the mounting column 2 and welded to the mounting column 2. The second reinforcing member 4 is arranged along the radial direction of the mounting column 2 and welded to the mounting column 2.

[0036] The first reinforcement 3 is arranged along the axial direction of the mounting column 2, that is, its length direction is consistent with the extension direction of the mounting column 2. This arrangement enables the first reinforcement 3 to directly enhance the bearing capacity and stability of the mounting column 2 in the axial direction (that is, the length direction). At the same time, since it is welded to the mounting column 2, the connection strength between the two is significantly improved, effectively preventing the mounting column 2 from being deformed or failing due to the action of axial force. Unlike the first reinforcement 3, the second reinforcement 4 is arranged along the radial direction of the mounting column 2, that is, its width or thickness direction is consistent with the diameter direction of the mounting column 2. This arrangement enables the second reinforcement 4 to enhance the stability of the mounting column 2 in the transverse direction (that is, perpendicular to the length direction), and prevent the connection between the mounting column 2 and the mounting hole 11 from being twisted or broken due to lateral force or torque. Similarly, through the welding connection with the mounting column 2, the second reinforcement 4 also significantly improves the strength and rigidity of the connection.

[0037] The first reinforcement 3 and the second reinforcement 4 reinforce the mounting column 2 in the axial and radial dimensions respectively, forming an all-round support structure. This multi-dimensional reinforcement method enables the mounting column 2 to maintain high stability and load-bearing capacity under various stress conditions. The welding connection between the two reinforcements and the mounting column 2 not only increases the contact area, but also achieves a firm bond between the materials through the fusion effect of the welding process to form an integral structure. This combination method greatly improves the strength and rigidity of the connection, and also helps to optimize the stress distribution of the mounting column 2 and its surrounding structures. When subjected to external forces, the first reinforcement 3 and the second reinforcement 4 can share part of the stress, reduce the burden on the mounting column 2 and its connection, and effectively prevent connection failure, thereby significantly improving the structural stability of the entire subframe mounting bracket, which is not only beneficial to improving the overall performance of the vehicle, but also can improve driving safety to a certain extent.

[0038] Preferably, if Figure 3 As shown, the first reinforcement member 3 is a first reinforcement plate 31. The surface of the first reinforcement plate 31 is provided with a strip groove 32 extending along the axial direction of the mounting column 2. A portion of the mounting column 2 is located in the strip groove 32 and is in contact with the inner wall of the strip groove 32. The mounting column 2 is welded to the inner wall of the strip groove 32.

[0039] The strip groove 32 extends along the axial direction of the mounting column 2, providing a precise positioning reference for the mounting column 2, so that the mounting column 2 can maintain the correct position and angle during the installation process, avoiding problems such as loose connection or uneven force due to installation deviation. At the same time, the inner wall of the groove fits tightly with the outer surface of the mounting column 2, increasing the contact area between the two, which is not only conducive to heat transfer and material fusion during welding, but also can disperse stress when subjected to force, reduce local stress concentration, and improve the bearing capacity of the connection. A portion of the mounting column 2 is located in the strip groove 32 and is welded to the inner wall of the groove, so that the mounting column 2 and the first reinforcing plate 31 form an integral connection structure. This structure can jointly bear the load when subjected to external force, thereby improving the strength and rigidity of the connection. At the same time, since the design of the strip groove 32 increases the contact area and weld length, the bearing capacity and stability of the connection are further improved.

[0040] Preferably, if Figure 4 As shown, the second reinforcement member 4 is a second reinforcement plate 41 , and a slot 42 is provided on the edge of the second reinforcement plate 41 . A portion of the mounting column 2 is located in the slot 42 and fits against the inner wall of the slot 42 , and the mounting column 2 is welded to the inner wall of the slot 42 .

[0041] In the present invention, the shape and size of the slot 42 match the cross-section of the mounting post 2, ensuring that the mounting post 2 can be accurately embedded therein and fit tightly against the inner wall of the slot 42. This embedded design not only increases the contact area between the mounting post 2 and the second reinforcing plate 41, but also helps to form a more secure connection during the welding process. The weld formed during the welding process firmly connects the two together, improving the strength and rigidity of the connection and further enhancing the stability of the mounting post 2 in the lateral direction (i.e., perpendicular to the axial direction). When the vehicle is subjected to lateral forces or torques during driving, the second reinforcing plate 41 can effectively disperse and absorb these forces, preventing the connection between the mounting post 2 and the mounting hole 11 from twisting or deformation.

[0042] Preferably, if Figure 2 and Figure 4 As shown, a first flange 43 is provided on the edge of the second reinforcing plate 41 , and a clamping slot 42 is provided on the first flange 43 . The first flange 43 is adhered to and fixed to the surface of the first reinforcing plate 31 by welding.

[0043] The first flange 43 increases the contact area between the second reinforcing plate 41 and the first reinforcing plate 31 and provides a basis for the setting of the slot 42. The first flange 43 and the surface of the first reinforcing plate 31 are fixedly connected through a welding process. During the welding process, the high temperature causes the two metal materials to penetrate and fuse with each other at the interface, forming an integral connection structure. This connection method is not only strong and durable, but also ensures a tight fit and stable connection between the first flange 43 and the first reinforcing plate 31. This allows the entire mounting bracket to maintain higher stability and load-bearing capacity when subjected to external forces. At the same time, the welded connection between the slot 42 and the mounting column 2 further enhances the strength and rigidity of the connection.

[0044] Preferably, if Figure 2 and Figure 3 As shown, a second flange 33 and a third flange 34 are respectively provided on two opposite sides of the first reinforcing plate 31 , and the second flange 33 and the third flange 34 are respectively welded to two opposite side walls of the cavity 12 .

[0045] The second flange 33 and the third flange 34 can fit tightly with the corresponding side walls of the cavity 12, thereby facilitating subsequent welding operations. The welding connection between the second flange 33 and the third flange 34 and the side walls of the cavity 12 can significantly enhance the connection strength between the first reinforcing plate 31 and the longitudinal beam 1. This multi-dimensional connection method enables the mounting column 2 to transfer the external force to the first reinforcing plate 31 and the longitudinal beam 1 when subjected to external force, so that they can jointly bear the load, thereby improving the overall load-bearing capacity and stability. Through welding connection, the first reinforcing plate 31, the second flange 33, the third flange 34 and the longitudinal beam 1 form an integral structure, which can maintain a high degree of shape stability when subjected to external force, reducing deformation and vibration.

[0046] Preferably, if Figure 2 and Figure 4 As shown, a fourth flange 44 and a fifth flange 45 are respectively provided on two opposite sides of the second reinforcing plate 41 , and the fourth flange 44 and the fifth flange 45 are respectively welded to two opposite side walls of the cavity 12 .

[0047] Similar to the second flange 33 and the third flange 34, the fourth flange 44 and the fifth flange 45 can fit tightly with the corresponding side walls of the cavity 12, thereby facilitating subsequent welding operations. The welded connection between the fourth flange 44 and the fifth flange 45 and the side walls of the cavity 12 significantly enhances the connection strength between the second reinforcing plate 41 and the longitudinal beam 1. This multi-dimensional connection method enables the mounting column 2 to transfer the external force to the second reinforcing plate 41 and the longitudinal beam 1 when subjected to external force, so that they can jointly bear the load, further improving the overall load-bearing capacity and stability. Through the welding connection, the second reinforcing plate 41, the fourth flange 44, the fifth flange 45 and the longitudinal beam 1 form an integral structure, which can maintain a high degree of shape stability when subjected to external forces, reducing deformation and vibration.

[0048] Preferably, if Figure 2 and Figure 4 As shown, the fourth flange 44 includes a first connecting segment 441 and a second connecting segment 442, and the fifth flange 45 includes a third connecting segment 451 and a fourth connecting segment 452. The first connecting segment 441 is welded to the side wall of the cavity 12, the second connecting segment 442 is abutted against the second flange 33 and welded to the second flange 33, the third connecting segment 451 is welded to the side wall of the cavity 12, and the fourth connecting segment 452 is abutted against the third flange 34 and welded to the third flange 34.

[0049] The first connecting section 441 is directly welded to a side wall of the cavity 12, ensuring a firm connection between the fourth flange 44 and the longitudinal beam 1, and enhancing the stability of the overall structure. The second connecting section 442 is abutted against the second flange 33 of the first reinforcing plate 31 and welded to the second flange 33, enhancing the connection strength between the second reinforcing plate 41 and the first reinforcing plate 31. The third connecting section 451 is directly welded to the other side wall of the cavity 12, ensuring a firm connection between the fifth flange 45 and the cavity 12 structure, and enhancing the stability of the overall structure. The fourth connecting section 452 is abutted against the third flange 34 of the first reinforcing plate 31 and welded to the third flange 34, further enhancing the connection strength between the second reinforcing plate 41 and the first reinforcing plate 31. As a result, the first reinforcing plate 31, the second reinforcing plate 41 and the longitudinal beam 1 form a highly integrated overall structure. This structure can maintain a high shape stability when subjected to external forces, reduce the deformation and vibration of the overall structure, and further prevent the occurrence of problems such as deformation and cracking of the installation point due to uneven force or overload.

[0050] Preferably, if Figure 2 and Figure 3 As shown, a sixth flange 35 is provided at the bottom of the first reinforcing plate 31 , and the sixth flange 35 is welded to the bottom of the cavity 12 , and / or the second reinforcing plate 41 is welded to the bottom of the cavity 12 .

[0051] The sixth flange 35 is welded to the bottom of the cavity 12. This welding method ensures the connection strength between the two and significantly enhances the vertical stability of the first reinforcing plate 31. This allows the first reinforcing plate 31 to better resist vertical deformation and damage when subjected to external forces, thereby improving the stability and durability of the first reinforcing plate 31. By welding the second reinforcing plate 41 to the bottom of the cavity 12, the horizontal stability of the second reinforcing plate 41 is significantly enhanced, allowing the second reinforcing plate 41 to better resist horizontal deformation and damage when subjected to external forces, thereby improving the stability and durability of the second reinforcing plate 41.

[0052] In addition, the utility model also provides a vehicle, which includes the above-mentioned subframe mounting bracket.

Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
