[0021] Powertrain mounts are crucial components used to connect the powertrain, including the motor and reducer, to the vehicle frame or body. Their primary functions are to support and position the powertrain and isolate vibrations between the frame / body and the powertrain. Powertrain mounts must possess sufficient strength to support the powertrain while also being resistant to high temperatures and corrosion. In related technologies, powertrain mounts are press-fitted with rubber bushings featuring outer metal rings to achieve vibration damping; however, this press-fitting process is complex and requires precise control.

[0022] This application provides a suspension bracket 1, which is applied to a vehicle. Figure 1 This is a schematic diagram of a three-dimensional assembly structure of a suspension bracket according to an exemplary embodiment of this application. Figure 2 This is an exploded three-dimensional structural diagram of a suspension bracket according to an exemplary embodiment of this application, as shown below. Figure 1 , Figure 2As shown, the suspension bracket 1 includes a bracket body 11 and a shock-absorbing component 13. The bracket body 11 includes a first hole 112, and the shock-absorbing component 13 is located in the first hole 112. The shock-absorbing component 13 includes an elastic bushing main spring 131 and an inner core 132. The elastic bushing main spring 131 includes an inner side 1312 and an outer side 1311. The inner side 1312 encloses an installation space, the inner core 132 is assembled in the installation space, and the outer side 1311 is fixed to the first hole 112.

[0023] The aforementioned bracket body 11 includes a first hole 112. One of the powertrain or the vehicle frame is fixed to the bracket body. The shock absorber 13 located at the first hole 112 can be fixed to the other powertrain or the vehicle frame 21 to achieve a shock-absorbing connection between the powertrain and the vehicle frame 21. The shock absorber 13 includes an elastic bushing main spring 131 and an inner core 132. The elastic bushing main spring 131 includes an inner side 1312 and an outer side 1311. The inner side 1312 encloses an installation space, the inner core 132 is assembled in the installation space, and the outer side 1311 is fixed to the first hole 112. Fixing the shock absorber 13 by connecting the outer side 1311 of the elastic bushing main spring to the first hole 112 of the bracket body 11 helps to reduce the cost of the shock absorber 13 and simplify its assembly process. In addition, the outer side 1311 of the elastic bushing main spring 131 is directly connected to the first hole 112, eliminating the need for the outer metal ring between the elastic bushing main spring 131 and the bracket body 11 and the installation process of the two, further reducing the weight of the electric vehicle suspension bracket 1 and improving assembly efficiency and fitting accuracy.

[0024] In some embodiments, the bracket body 11 includes an injection-molded body, which effectively reduces the weight of the entire vehicle compared to steel plate stamping and welding brackets, cast iron or cast steel brackets, or aluminum alloy brackets, thus contributing to energy conservation and emission reduction. The outer surface 1311 of the elastic bushing main spring 131 and the first hole 112 are fixed by injection molding during the injection molding process of the bracket body 11. The bracket body 11 of the suspension bracket 1 can be injection molded from composite materials such as polyhexamethylene adipamide glass fiber reinforced PA66, polycaprolactam PA6, or equivalent materials, which greatly reduces the weight of the suspension bracket 1. On the other hand, the shock absorption component 13 can be directly fixed to the bracket body during the injection molding stage during the manufacturing process of the bracket body 11. The outer surface 1311 of the elastic bushing main spring 131 and the first hole 112 are fixed by injection molding, eliminating the need for the outer metal ring between the elastic bushing main spring 131 and the bracket body 11 and the installation process of the two, further reducing the weight of the electric vehicle suspension bracket 1, improving assembly efficiency and fitting accuracy, and also meeting high strength requirements. In addition, since the support body is made of composite material injection molding, no further anti-corrosion treatment is required, which reduces costs.

[0025] In some embodiments, the support body 11 includes at least one hollow structure 113, and the hollow structure 113 is provided with reinforcing ribs 1131. By providing the hollow structure 113 and the reinforcing ribs 1131, on the one hand, it is beneficial to the injection molding of the support body 11, and on the other hand, it further reduces the weight of the support body 11, reduces the difficulty of injection molding, and improves the strength of the support body 11.

[0026] For example, the injection-molded composite material of the main body 11 is PA66-GF50, with a density of 1.57 g / cm3 and a wall thickness of 2 mm to 6 mm, mostly around 3.5 mm. A denser perforated structure 113 is incorporated to compensate for the deficiencies caused by the reduced wall thickness and material change, based on structural strength requirements. Although the volume is similar to that of the original aluminum support structure with a wall thickness of 4 mm to 8 mm, mostly around 6 mm, the weight is reduced by approximately 50%.

[0027] In some embodiments, the inner core 132 includes a metal structure having a first external connection hole. The metal structure is connected to the powertrain, frame 21, or body through the first external connection hole, thereby improving connection strength.

[0028] like Figure 3 As shown, the suspension bracket 1 includes a rigid connector 12, and the bracket body 11 includes a second hole 111, with the rigid connector 12 located in the second hole 111. The rigid connector 12 located in the second hole 111 is fixed to one of the powertrain or the vehicle frame. The shock absorber assembly 13 located in the first hole 112 can be fixed to the other of the powertrain or the vehicle frame 21 to achieve a shock absorber connection between the powertrain and the vehicle frame 21. The bracket body 11 may include an injection-molded body. The rigid connector 12 and the second hole 111 are fixed by injection molding during the injection molding process of the bracket body 11. The rigid connector 12 is provided with a second external connection hole. The rigid connector 12 is connected to the powertrain, the vehicle frame 21, or the vehicle body through the first external connection hole, improving the connection strength.

[0029] The rigid connector 12 is made of metal to improve the connection strength. The rigid connector 12 can be a metal liner pre-embedded in the injection molding body along with the bracket body 11. Connectors such as bolts pass through the metal liner and are connected to the frame 21 or electric drive and body.

[0030] In the above embodiment, the rigid connector 12 includes a tubular connecting structure. Axially, the rigid connector 12 includes end sections 121 at both ends and an intermediate section 122 between the two end sections 121. The cross-sectional area of ​​the intermediate section 122 perpendicular to the axial direction is smaller than that of the end sections 121 perpendicular to the axial direction. That is, viewed from the axial section along the tubular connecting structure, the rigid connector 12 is I-shaped, which prevents the rigid connector 12 from rotating within the fixing hole.

[0031] The end face shape of the end section 121 includes at least one of circular, elliptical, and polygonal shapes. When viewed from the end, the end faces of both ends of the rigid connector 12 can be circular, elliptical, or polygonal such as hexagonal or octagonal, to prevent the rigid connector 12 from rotating within the fixing hole.

[0032] This disclosure further provides a vehicle including a powertrain, a frame 21 and the aforementioned suspension bracket 1, wherein one of the powertrain and the frame 21 is fixedly connected to the inner core 132, and the other of the powertrain and the frame 21 is fixedly connected to the bracket body 11.

[0033] For example, the suspension bracket 1 also includes a rigid connector 12, which is located in the second hole 111 of the bracket body 11. The powertrain is fixedly connected to one of the inner core 132 and the rigid connector 12, and the frame 21 is fixedly connected to the other of the inner core 132 and the rigid connector 12. Figure 4 As shown, the rigid connector 12 can be fixedly connected to the powertrain, and the inner core 132 of the shock absorber 13 can be fixedly connected to the frame 21.

[0034] The bracket body 11 includes a second hole 111 and a first hole 112. A rigid connector 12 located in the second hole 111 and a damping assembly 13 located in the first hole 112 can be fixed to the powertrain and the frame 21 respectively, achieving a damping connection between the powertrain and the frame 21. The damping assembly 13 includes an elastic bushing main spring 131 and an inner core 132. The elastic bushing main spring 131 includes an inner side 1312 and an outer side 1311. The inner side 1312 encloses an installation space, the inner core 132 is assembled into the installation space, and the outer side 1311 is fixed to the first hole 112. Fixing the damping assembly 13 by connecting its outer side 1311 to the first hole 112 of the bracket body 11 helps reduce the cost of the damping assembly 13 and simplifies its assembly process. In addition, the outer side 1311 of the elastic bushing main spring 131 is directly connected to the first hole 112, eliminating the need for the outer metal ring between the elastic bushing main spring 131 and the bracket body 11 and the installation process of the two, further reducing the weight of the electric vehicle suspension bracket 1 and improving assembly efficiency and fitting accuracy.
