The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0025] Reference below Figure 1 A suspension bracket 1 according to an embodiment of the present invention is described. The suspension bracket 1 can be installed on a vehicle.

[0026] According to the suspension bracket 1 of the first embodiment of the present utility model, Figure 1 As shown, the suspension bracket 1 may include: a first bracket body 10 and a second bracket body 20, the first bracket body 10 is formed with a first assembly portion 11 and a second assembly portion 12, the first assembly portion 11 is used to connect to the vehicle body, and the second assembly portion 12 is used to connect to the powertrain, the second bracket body 20 is fixedly connected to the first bracket body 10, and an angle is formed between the second bracket body 20 and the first bracket body 10, and the second bracket body 20 is used to connect to the powertrain.

[0027] It should be noted that in the relevant technology, multiple connection points between the existing suspension bracket and the powertrain are located in the same plane, the structure of the suspension bracket is weak, the modal frequency of the suspension bracket is low, and the vibration isolation performance of the suspension bracket is poor, which can easily cause problems such as vehicle roar caused by powertrain vibration.

[0028] Based on this, the embodiment of the present application proposes a suspension bracket 1, which can be connected between the vehicle body and the powertrain. The suspension bracket 1 can play the role of connecting the vehicle body and the powertrain, supporting the powertrain, limiting the movement of the powertrain, and blocking and attenuating the vibration of the powertrain. The first bracket body 10 is formed with a first assembly portion 11 and a second assembly portion 12. The first assembly portion 11 and the second assembly portion 12 can be spaced apart. The first assembly portion 11 can be used to connect to the vehicle body. The first assembly portion 11 can be connected to the vehicle body by bolt connection, clamping, etc. The second assembly portion 12 can be used for connection to the powertrain. The second assembly portion 12 can be connected to the powertrain by bolt connection, clamping, etc. The first bracket body 10 can be connected between the vehicle body and the powertrain.

[0029] The second bracket body 20 can be welded to the first bracket body 10, and the second bracket body 20 and the first bracket body 10 can be integrally formed. The second bracket body 20 can form an angle with the first bracket body 10, and the second bracket body 20 can support the first bracket body 10, which helps improve the structural strength and stability of the suspension bracket 1 and improve the modal frequency of the suspension bracket 1. The second bracket body 20 can be connected to the powertrain through methods such as snap-fitting or bolting. The connection between the second bracket body 20 and the powertrain and the second assembly portion 12 can be located on different planes, that is, the connection between the second bracket body 20 and the powertrain and the second assembly portion 12 are not coplanar. This helps break the vibration transmission path between the powertrain and the suspension bracket 1, thereby reducing the transmission of vibration noise to the vehicle body. Both the first bracket body 10 and the second bracket body 20 can be used for connection to the powertrain, which helps improve the connection strength between the suspension bracket 1 and the powertrain.

[0030] In the embodiment of the present application, the suspension bracket 1 has high structural strength and good stability, which is beneficial to improving the stability of the connection between the powertrain and the vehicle body. The modal frequency of the suspension bracket 1 is high, and multiple connection points between the suspension bracket 1 and the powertrain are not coplanar, which can reduce the risk of resonance between the suspension bracket 1 and the powertrain, and can better block and attenuate the vibration of the powertrain, reduce the vibration and noise inside the vehicle, and improve ride comfort.

[0031] In some embodiments of the present invention, the second bracket body 20 is located on one side of the first bracket body 10 , one end of the second bracket body 20 is connected to the first bracket body 10 , and the second bracket body 20 is perpendicular to the first bracket body 10 .

[0032] Along the thickness direction of the first bracket body 10, the second bracket body 20 can be located on one side of the first bracket body 10. The second bracket body 20 can support the first bracket body 10. The second bracket body 20 can form an angle with the first bracket body 10. The angle can be a right angle or a right angle. The second bracket body 20 can be arranged perpendicular to the first bracket body 10. The second bracket body 20 can extend along the arrangement direction of the first bracket body 10 and the second bracket body 20, which is conducive to improving the stability of the suspension bracket 1 structure. One end of the second bracket body 20 can be welded to the first bracket body 10. The second bracket body 20 can be integrally formed with the first bracket body 10. The connection between the second bracket body 20 and the first bracket body 10 can be located between the first assembly portion 11 and the second assembly portion 12, which is conducive to improving the balance and stability of the suspension bracket 1.

[0033] In some embodiments of the present invention, the second bracket body 20 is correspondingly connected to the middle position of the first bracket body 10 .

[0034] The second bracket body 20 can be connected to the middle portion of the first bracket body 10. The second bracket body 20 and the first bracket body 10 are perpendicular to each other, and the suspension bracket 1 can be constructed into a T-shaped structure, making the suspension bracket 1 compact and helping to reduce the space occupied by the suspension bracket 1. By arranging the second bracket body 20 to be connected to the middle portion of the first bracket body 10, the stability of the suspension bracket 1 structure can be improved, and the load can be more effectively distributed and transferred, which helps to extend the service life of the suspension bracket 1.

[0035] In some embodiments of the present invention, the second bracket body 20 is formed with a third assembly portion 21 , and the third assembly portion 21 is used to connect with the powertrain.

[0036] The second bracket body 20 can be connected to the powertrain through the third assembly part 21, and the third assembly part 21 can be connected to the powertrain through bolt connection, clamping, etc. The third assembly part 21 and the second assembly part 12 can both be used to connect to the powertrain. Under the joint action of the third assembly part 21 and the second assembly part 12, it is beneficial to improve the connection strength between the suspension bracket 1 and the powertrain. The third assembly part 21 is located on the second bracket body 20, and the second assembly part 12 is located on the first bracket body 10. The second bracket body 20 is perpendicular to the first bracket body 10. The third assembly part 21 and the second assembly part 12 are not located on the same plane. The non-coplanar design can help break the vibration transmission path, thereby reducing the transmission of powertrain vibration to the vehicle body, which is beneficial to improving the NVH performance of the vehicle and reducing the vibration and noise inside the vehicle.

[0037] In some embodiments of the present invention, the first assembly portion 11 , the second assembly portion 12 and the third assembly portion 21 are all configured as assembly holes, and the central axis of the second assembly portion 12 and the central axis of the third assembly portion 21 are staggered.

[0038] The first assembly portion 11, the second assembly portion 12, and the third assembly portion 21 are all configured as assembly holes. The first assembly portion 11 can be connected to the vehicle body via bolts, the second assembly portion 12 can be connected to the powertrain via bolts, and the third assembly portion 21 can be connected to the powertrain via bolts. The central axis of the second assembly portion 12 and the central axis of the third assembly portion 21 can extend in different directions. By staggering the central axis of the second assembly portion 12 and the central axis of the third assembly portion 21, the suspension bracket 1 can be connected to the powertrain in different directions, which helps reduce stress concentration in the suspension bracket 1, improves the structural strength of the suspension bracket 1, and enhances the ability of the suspension device 1 to support the powertrain, helping to reduce the transmission of vibration and noise, thereby improving the NVH performance of the entire vehicle.

[0039] As an example, the second assembly portion 12 may have a plurality of assembly holes, and all of the plurality of assembly holes may be used for connection with the powertrain, which is beneficial to improving the connection strength between the suspension bracket 1 and the powertrain.

[0040] In some embodiments of the present invention, the first assembly portion 11, the second assembly portion 12 and the third assembly portion 21 are all constructed as assembly holes, the central axis of the second assembly portion 12 extends along the first direction, and the central axis of the third assembly portion 21 extends along the second direction, and the first direction and the second direction are perpendicular to each other.

[0041] The first assembly portion 11, the second assembly portion 12 and the third assembly portion 21 are all configured as assembly holes. The first assembly portion 11 can be connected to the vehicle body by bolts, the second assembly portion 12 can be connected to the powertrain by bolts, and the third assembly portion 21 can be connected to the powertrain by bolts. The central axis of the second assembly portion 12 can extend along the first direction, and the assembly hole of the second assembly portion 12 can pass through the first bracket body 10 along the first direction. When the suspension bracket 1 is as shown in FIG. Figure 1 When setting the direction, the first direction can be Figure 1 The central axis of the third assembly portion 21 extends along the second direction, and the assembly hole of the third assembly portion 21 can penetrate the second bracket body 20 along the second direction. Figure 1 When setting the direction, the second direction can be Figure 1 In the X direction, the first direction is perpendicular to the second direction.

[0042] By setting the central axis of the second assembly portion 12 and the central axis of the third assembly portion 21 to be perpendicular to each other, the suspension bracket 1 can be assembled with the powertrain in different directions, and the stress concentration of the suspension bracket 1 can be reduced, thereby avoiding the structural strength of the suspension bracket 1 being affected by stress concentration in a single direction.

[0043] In some embodiments of the present invention, a third assembly portion 21 is formed at the end of the second bracket body 20 facing away from the first bracket body 10 .

[0044] One end of the second bracket body 20 is connected to the first bracket body 10. The second bracket body 20 is formed with a third assembly portion 21, which can be located at the other end of the second bracket body 20 facing away from the first bracket body 10. The second bracket body 20 can be connected to the powertrain via the third assembly portion 21. Both the third assembly portion 21 and the second assembly portion 12 can be used for connection to the powertrain. The separation of the second assembly portion 12 and the third assembly portion 21 can evenly distribute force on the suspension bracket 1, reducing stress concentration, thereby improving the structural strength of the suspension bracket 1 and extending its service life. The third assembly portion 21 can also provide additional support for the powertrain, thereby increasing the strength of the connection between the suspension bracket 1 and the powertrain.

[0046] The suspension bracket 1 can be made by stamping, die-casting, etc., and the first bracket body 10 and the second bracket body 20 are integrally formed, which is beneficial to improving the overall structural strength of the suspension bracket 1, simplifying the processing flow of the suspension bracket 1, reducing costs, and improving the production accuracy of the suspension bracket 1.

[0047] In some embodiments of the present invention, at least one of the first bracket body 10 and the second bracket body 20 is formed with a weight reduction structure 30 .

[0048] The first bracket body 10 can be formed with a weight-reducing structure 30, or the second bracket body 20 can be formed with a weight-reducing structure 30, or both the first bracket body 10 and the second bracket body 20 can be formed with a weight-reducing structure 30.
