Description

Technical Field

[0001] This utility model relates to the field of automotive body technology, and in particular to a load-bearing structure for a powertrain of a new energy vehicle. Background Technology

[0002] The powertrains of pure electric vehicles are generally heavy and have high torque, requiring the installation of suspension pad assemblies to support their weight, limit the relative positions of the powertrain and surrounding components, and reduce the transmission of noise and vibration to the passenger compartment, thereby improving vehicle safety and ride comfort. However, when the integrated motor is positioned at the front, the span between the motor assembly mounting point and the left and right longitudinal beams of the vehicle body is often large. Furthermore, the front compartment also needs to house components such as the compressor, battery, and water pump, making their securing a pressing issue. To meet the installation requirements of the integrated motor, a new load-bearing structure for the powertrain of new energy vehicles needs to be invented. Utility Model Content

[0003] The purpose of this utility model is to provide a load-bearing structure for the powertrain of new energy vehicles, solving the problem of arranging various installation points when the integrated motor is placed at the front.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A load-bearing structure for a new energy vehicle powertrain includes a front crossbeam and a rear crossbeam fixedly connected to the left and right longitudinal beams of the vehicle body. A left longitudinal beam and a right longitudinal beam are fixedly connected to the left and right sides of the front and rear crossbeams, respectively. The front crossbeam, rear crossbeam, left longitudinal beam, and right longitudinal beam are fixedly connected to form a load-bearing assembly. A water pump mounting bracket assembly is fixedly connected to the front side of the load-bearing assembly, and a battery mounting bracket assembly is fixedly connected to the upper end of the load-bearing assembly.

[0006] Preferably, in conjunction with the above scheme, a left reinforcing longitudinal beam is provided on the left side of the left longitudinal beam, and a right reinforcing longitudinal beam is provided on the right side of the right longitudinal beam. The left and right reinforcing longitudinal beams are fixedly connected with the front and rear crossbeams to form a rectangular structure.

[0007] Preferably, in conjunction with the above scheme, a middle reinforcing longitudinal beam is provided between the left reinforcing longitudinal beam and the right reinforcing longitudinal beam, and the front and rear ends of the middle reinforcing longitudinal beam are fixedly connected to the front crossbeam and the rear crossbeam, respectively.

[0008] Preferably, in conjunction with the above scheme, the water pump mounting bracket assembly includes a first water pump mounting bracket, a second water pump mounting bracket, and a third water pump mounting bracket, wherein the first water pump mounting bracket, the second water pump mounting bracket, and the third water pump mounting bracket are all fixedly connected to the front side of the front crossbeam.

[0009] Preferably, in conjunction with the above scheme, the cross-sections of the first water pump mounting bracket, the second water pump mounting bracket, and the third water pump mounting bracket are all L-shaped structures.

[0010] Preferably, in conjunction with the above scheme, the battery mounting bracket assembly includes a first water pump mounting bracket, a second water pump mounting bracket, and a third water pump mounting bracket. The first water pump mounting bracket and the second water pump mounting bracket are fixedly connected to the upper end face of the front crossbeam, and the third water pump mounting bracket is fixedly connected to the upper end face of the rear crossbeam.

[0011] Preferably, in conjunction with the above scheme, the first water pump mounting bracket, the second water pump mounting bracket, and the third water pump mounting bracket are all square tube structures.

[0012] Preferably, in conjunction with the above scheme, longitudinal beam mounting sleeves are fixedly installed on both the left and right sides of the front crossbeam and the rear crossbeam, and the longitudinal beam mounting sleeves are fixedly connected to the left and right longitudinal beams of the vehicle body by screwing.

[0013] Preferably, in conjunction with the above scheme, several sets of left suspension mounting sleeves and right suspension mounting sleeves are respectively provided on the left longitudinal beam and the right longitudinal beam.

[0014] This utility model also includes a car, which is equipped with the above-mentioned new energy vehicle powertrain load-bearing structure.

[0015] The beneficial effects of this utility model are as follows: The load-bearing assembly structure of this utility model adopts square steel welding, and some brackets are stamped and then welded to the load-bearing assembly as a whole. Fasteners are connected to the square steel body by welding or riveting, and most fasteners and brackets are interchangeable, resulting in a high degree of standardization. Compared with the current traditional stamping and welding or casting structures, this structure saves a lot of stamping mold and casting mold costs, reducing production and development costs. The single-piece structure is simple, the process is mature, and there are no technical barriers in the production process, allowing for rapid production. Furthermore, the corresponding mounting holes can be quickly adjusted when the positions and installation points of key components in the forward compartment change without affecting the main structure, resulting in a high degree of platformization. Ultimately, this allows for a simple forward compartment suspension structure with a small footprint, achieving the goals of easy installation, cost reduction, and shock absorption. The forward compartment components are easy to install, flexible in position, highly standardized, simple to manufacture, and reduce the cost of themselves and surrounding fasteners, showing good application prospects.
