[0058] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0060] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0061] Currently, traditional vehicle motor mounting structures generally employ single-point or simple two-point fixing installation methods. This results in a simplistic overall layout and poor spatial adaptability. Limited by the structural design of conventional mounting brackets, the bracket body cannot create a dedicated support space, making it difficult to partition and partially enclose the motor's end and sides for positioning. In actual assembly, the motor can only be fixed by contact with the bracket end face, lacking spatial constraints and enclosure. This leads to low motor assembly alignment accuracy and poor tolerance for misalignment, making it impossible to achieve embedded motor positioning. Over long-term service, the motor is prone to radial and axial misalignment and slight movement, significantly impacting the overall integrity and consistency of the motor installation, and making it difficult to meet the production requirements of high-precision vehicle assembly.

[0062] Meanwhile, the existing motor mounting system's vibration damping structure layout design is unreasonable. Traditional mountings often use a single damping point or a same-side damping arrangement, failing to form a multi-point elastic damping system that coordinates the motor end and side. The damping components are scattered and cannot be precisely matched with the bracket support structure. When the motor operates at high speed, it continuously generates high-frequency vibrations and torque impacts. This vibration cannot be effectively buffered and dissipated, and is easily transmitted directly to the vehicle frame longitudinal beams through the highly rigid bracket structure. At the same time, vehicle body vibrations caused by road bumps are also transmitted in reverse to the motor body. The combined effect of bidirectional vibrations significantly aggravates the vehicle's noise and vibration problems, resulting in poor NVH performance. Under long-term vibration loads, it is also prone to faults such as loosening of motor connection bolts and bearing wear, reducing the motor's service life.

[0063] In addition, existing conventional motor mounting brackets are mostly simple straight plates or single-bend structures. Their overall structural design is simplistic and lacks rational mechanical design. They do not incorporate segmented bending transition structures or reinforced guide structures for motor load conditions, resulting in insufficient overall bending and torsional stiffness. When subjected to the motor's own weight, operational vibration loads, and vehicle bump impact loads, the bracket experiences severe stress concentration, and localized stress overload can easily lead to bracket deformation, cracking, and other failures. Furthermore, traditional brackets only provide point support, offering weak overall support for the motor, resulting in uneven stress distribution at multiple points and further exacerbating the instability of the motor suspension installation. The overall structural strength, load-bearing capacity, and adaptability to operating conditions are insufficient to meet the high-load, high-durability requirements of new energy vehicles.

[0064] Combination Figures 1 to 9 As shown, according to a specific embodiment of this application, a motor suspension bracket is provided.

[0065] Specifically, a motor mount bracket includes: a front mount support 10, which has a front support space and is connected to one end of a motor 20, with a portion of the motor 20 located within the front support space; the front mount support 10 includes a front mount bracket assembly and a front damping assembly, which is connected to a frame longitudinal beam 40 via the front damping assembly; and a rear mount support 30, which is disposed at a distance from the front mount support 10 and has a rear support space, which is connected to the side of the motor 20, with a portion of the motor 20 located within the rear support space; the rear mount support 30 includes a rear mount bracket assembly 32 and a rear damping assembly 31, which is connected to the frame longitudinal beam 40 via the rear damping assembly 31.

[0066] By applying the technical solution of this invention, the front and rear suspension support parts are spaced apart to form a accommodating support from one end and the side of the motor, which can stably support and position the motor, improve the overall rigidity of the motor mounting structure, distribute the force on the bracket, reduce the risk of stress concentration, and the independent front and rear vibration damping components can attenuate the vibration of the motor in different directions, reduce the transmission of vibration to the longitudinal beam of the frame, improve the vibration and noise of the whole vehicle, and at the same time, the front and rear support space facilitates the motor assembly and alignment, improves the assembly convenience, and solves the technical problem that the motor vibration of the traditional motor suspension bracket is easily transmitted to the longitudinal beam of the frame.

[0067] Furthermore, the front damping assembly and the rear damping assembly 31 are structurally identical.

[0068] In this embodiment, the front and rear vibration damping components 31 are structurally identical, enabling universal interchangeability of the vibration damping structures, effectively reducing the types of parts, lowering the production and manufacturing costs and material management costs of the bracket, while ensuring that the vibration damping performance of the front suspension support 10 and the rear suspension support 30 is consistent, so that the motor 20 is subjected to uniform force and the vibration isolation effect is more balanced and stable.

[0069] Specifically, the rear suspension bracket assembly 32 includes two rear suspension positioning frames, which are symmetrically arranged about the motor 20 and form a rear support space. The rear damping assembly 31 includes two rear damping units, which are arranged one-to-one with the two rear suspension positioning frames. One end of each rear suspension positioning frame is connected to the motor 20, and the other end of each rear suspension positioning frame is connected to the vehicle frame longitudinal beam 40 through the corresponding rear damping unit.

[0070] In this embodiment, the rear suspension bracket assembly 32 uses two symmetrically arranged rear suspension positioning frames to form a rear support space and cooperates with two sets of one-to-one corresponding rear damping units to connect with the frame longitudinal beam 40. This can form a double-sided symmetrical support and multi-point elastic damping constraint for the motor 20, with good force uniformity, which can effectively improve the lateral installation stability of the motor 20, suppress motor swaying and deviation, and greatly optimize the overall vibration isolation and limiting effect.

[0071] In this embodiment, at least one of the two rear suspension positioning frames includes: a rear suspension connecting plate 301, one end of which is connected to the motor 20, and the other end of which is connected to the frame longitudinal beam 40 via a rear damping unit; and a guide rib assembly, which is located on one side of the rear suspension connecting plate 301, is positioned close to the rear damping unit, extends along the length of the rear suspension connecting plate 301, and is connected to the rear suspension connecting plate 301.

[0072] In this embodiment, the rear suspension positioning frame is provided with a rear suspension connecting plate 301 and a guide rib assembly that extends along the length of the rear suspension connecting plate 301 and is arranged close to the rear vibration damping unit. This can improve the bending and torsional resistance of the rear suspension connecting plate 301, distribute the load, reduce the risk of stress concentration in the rear suspension connecting plate 301, and ensure the structural strength and operational reliability of the lateral support of the motor 20.

[0073] Specifically, the rear suspension connecting plate 301 includes: a first rear connecting plate 3011, one end of which is connected to the motor 20; a second rear connecting plate 3012, which is set at a preset angle to the first rear connecting plate 3011, and one end of the second rear connecting plate 3012 is connected to the other end of the first rear connecting plate 3011; and a third rear connecting plate 3013, which is set at a preset angle to the second rear connecting plate 3012, one end of which is connected to the other end of the second rear connecting plate 3012, and the other end of the third rear connecting plate 3013 is connected to the frame longitudinal beam 40 via a rear damping unit; wherein, the guide rib assembly includes a first reinforcing rib 302 and a second reinforcing rib 303, the second reinforcing rib 303 being connected to the second rear connecting plate 3012 and the first rear connecting plate 3011 respectively, and the first reinforcing rib 302 being connected to the third rear connecting plate 3013 and the second rear connecting plate 3012 respectively.

[0074] In this embodiment, the rear suspension connecting plate 301 is composed of a first rear connecting plate 3011, a second rear connecting plate 3012, and a third rear connecting plate 3013 connected in sequence at a preset angle. With the first reinforcing rib 302 and the second reinforcing rib 303 respectively spanning the adjacent connecting plates, it can reasonably transfer the load of the motor 20, improve the structural rigidity of the connection of the bent plate segment, disperse stress, reduce the risk of deformation of the rear suspension connecting plate 301 under alternating load, and ensure the lateral support stability of the motor 20.

[0075] In this embodiment, the front damping assembly includes a first front damping unit 11 and a second front damping unit 12. One end of the front suspension bracket assembly is connected to the first longitudinal beam 401 of the frame longitudinal beam 40 through the first front damping unit 11, and the other end of the front suspension bracket assembly is connected to the second longitudinal beam 402 of the frame longitudinal beam 40 through the second front damping unit 12.

[0076] In this embodiment, the front damping assembly is provided with a first front damping unit 11 and a second front damping unit 12, so that the two ends of the front suspension bracket assembly are elastically connected to the first longitudinal beam 401 and the second longitudinal beam 402 of the frame longitudinal beam 40, forming double-sided elastic support points, which can evenly distribute the load at the front end of the motor 20, improve the stability of the front suspension support, isolate vibration in both directions, and avoid the off-center load problem caused by single-point support.

[0077] Furthermore, the front suspension bracket assembly includes: a front suspension connecting plate, a portion of which is connected to the motor 20, one end of which is connected to the first longitudinal beam 401 via a first front damping unit 11, and the other end of which is connected to the second longitudinal beam 402 via a second front damping unit 12; and a front suspension upright plate 124, which is located at the end of the motor 20, a portion of which is connected to the motor 20, and one end of which is connected to the front suspension connecting plate.

[0078] In this embodiment, the front suspension bracket assembly is provided with a front suspension connecting plate and a front suspension upright plate 124 that are connected to each other. The two ends of the front suspension connecting plate are connected to the first longitudinal beam 401 and the second longitudinal beam 402 through the first front damping unit 11 and the second front damping unit 12, respectively. The front suspension upright plate 124 abuts against the end of the motor 20, which can share the load at the front end of the motor 20, improve the overall structural rigidity of the front suspension bracket assembly, provide reliable support for the end of the motor 20 and achieve effective vibration isolation.

[0079] Specifically, the front suspension connecting plate includes: a first front connecting plate 121, one end of which is connected to the first front damping unit 11; a second front connecting plate 122, which is perpendicular to the first front connecting plate 121, one end of which is connected to the other end of the first front connecting plate 121; and a third front connecting plate 123, which is at a preset angle to the second front connecting plate 122, one end of which is connected to the other end of the second front connecting plate 121.

[0080] In this embodiment, the front suspension connecting plate is composed of a first front connecting plate 121, a second front connecting plate 122, a third front connecting plate 123, a fourth front connecting plate 125 and a transition plate connected in sequence. Each plate segment is connected to each other at a preset angle, which can construct a continuous and smooth load transmission path, disperse the load transmitted by the motor 20 to the front suspension bracket assembly, reduce local stress concentration, improve the overall bending and torsional resistance of the front suspension connecting plate, and stably support the end of the motor 20.

[0081] In this embodiment, the transition plate includes: a fifth front connecting plate 126, one end of which is connected to the third end of the fourth front connecting plate 125, and the fifth front connecting plate 126 and the third front connecting plate 123 are symmetrically arranged about the fourth front connecting plate 125; a sixth front connecting plate 127, one end of which is connected to the other end of the fifth front connecting plate 126, and the sixth front connecting plate 127 and the second front connecting plate 122 are symmetrically arranged about the fourth front connecting plate 125; and a seventh front connecting plate 128, one end of which is connected to the other end of the sixth front connecting plate 127, and the seventh front connecting plate 128 and the first front connecting plate 121 are symmetrically arranged about the fourth front connecting plate 125, and the seventh front connecting plate 128 is connected to the second front damping unit 12.

[0082] In this embodiment, the transition plate is composed of the fifth front connecting plate 126, the sixth front connecting plate 127, and the seventh front connecting plate 128. Each connecting plate is symmetrically arranged with the fourth front connecting plate 125 as the center, which can form a symmetrical load transfer path, evenly distribute the force on both sides, improve the torsional and bending resistance of the overall structure of the front suspension connecting plate, ensure that the load is smoothly transferred to the second front damping unit 12, and improve the structural stability of the front end support of the motor 20.

[0083] Furthermore, the front suspension connecting plate is integrally formed.
