Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an integrated bracket used in the cab connecting beam of an electric heavy-duty truck. Background Technology

[0002] Heavy-duty trucks typically have integrated front beam brackets at the front of their chassis. The front end of these brackets connects to the front beam, while the rear end connects to the chassis frame. The brackets also integrate other connecting mechanisms, with one bracket mounted on each side of the chassis. Current integrated brackets are available in both cast and simple stamped forms. However, current integrated brackets have limited functionality, excessive structural redundancy, are bulky, require significant installation space, and are inconvenient to assemble and disassemble. This hinders effective weight reduction, results in low assembly efficiency, poor stability, high costs, and prevents effective modular production. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides an integrated bracket for the cab connecting beam of a heavy truck, which has a high degree of modularity and low manufacturing cost.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a heavy truck cab connecting beam integrated bracket, including a main body, a steering connecting bracket, a radiator connecting bracket and an auxiliary connecting bracket arranged on the front side of the main body, a cab connecting bracket arranged on the back side of the main body, a frame connecting bracket arranged on one side of the main body, and an anti-collision connecting bracket arranged on the other side of the main body, and the entire main body structure is integrally formed.

[0005] The frame connecting frame has multiple first bases arranged on it. Adjacent first bases are connected by first arc-shaped connecting sections. Each first base has a first connecting through hole, through which bolts pass and connect to the frame body. To ensure the structural strength of the frame connecting frame, four first weight-reduction through holes are provided on it. These first weight-reduction through holes are placed between four adjacent first bases to reduce the weight of the frame connecting frame.

[0006] The radiator connecting bracket is positioned between the auxiliary connecting bracket and the steering connecting bracket. Multiple second bases are arranged on the radiator connecting bracket, and adjacent second bases are connected by a second arc-shaped connecting section. This second arc-shaped connecting section has a concave structure, further reducing the weight of the radiator connecting bracket and enhancing its structural strength. Second connecting through holes are opened on the second bases, and bolts pass through the corresponding second connecting through holes to connect with the radiator connecting bracket. While ensuring the structural strength of the radiator connecting bracket, a first weight-reducing groove is provided on the front side of the radiator connecting bracket, and a second weight-reducing groove is provided on the back side of the radiator connecting bracket. Neither the first nor the second weight-reducing groove penetrates the radiator connecting bracket, further reducing its weight.

[0007] The steering connecting frame is equipped with multiple third bases, each with a third connecting through hole. Bolts pass through the corresponding third connecting through holes and are connected to the steering system. To ensure the structural strength of the steering connecting frame, a third weight-reducing groove is provided on the steering connecting frame to reduce its structural strength. To further reduce the weight of the steering connecting frame, a third arc-shaped connecting section is provided on the outer side of the steering connecting frame.

[0008] The anti-collision connecting frame is placed between the steering connecting frame and the cab connecting frame. The anti-collision connecting frame includes two symmetrically arranged fourth bases. The fourth bases have fourth connecting through holes, and bolts pass through the fourth connecting through holes to connect with the anti-collision connecting frame. In order to improve the structural strength of the anti-collision connecting frame, a fourth arc-shaped connecting section is provided in the middle of the anti-collision connecting frame, and two fifth arc-shaped connecting sections are provided on the fourth bases to further reduce the weight of the anti-collision connecting frame.

[0009] The cab connecting frame is equipped with six fifth bases, and every two fifth bases form a gourd-shaped structure. The fifth bases have fifth connecting through holes, and bolts pass through the fifth connecting through holes to connect to the cab. The cab connecting frame also has two second weight-reducing through holes, which further reduce the weight of the cab connecting frame.

[0010] The auxiliary connecting frame is equipped with two sixth bases, each with a sixth connecting through hole; the auxiliary connecting frame also has a third weight-reducing through hole and a fourth weight-reducing groove, further reducing the weight of the auxiliary connecting frame.

[0011] The front side of the main body is provided with a fifth and a sixth weight-reducing groove; the back side of the main body is provided with a seventh, an eighth, a ninth, a tenth, and an eleventh weight-reducing groove. Under the premise of ensuring the structural strength of the main body, the weight of the main body is further guaranteed by arranging multiple weight-reducing grooves on the front and back sides of the main body.

[0012] While ensuring the strength of the main structure, the cab connecting frame and the frame connecting frame are connected by a concave sixth arc connecting section, which further reduces the weight of the main body.

[0013] Compared with the prior art, the specific beneficial effects of this utility model are as follows: This utility model integrates a frame connecting frame, radiator connecting frame, steering connecting frame, anti-collision connecting frame, cab connecting frame, and auxiliary connecting frame on a single main body. The weight of the one-piece molded structure is reduced by 22.3%, greatly improving the assembly efficiency of the entire vehicle. Multiple reinforcing ribs are arranged in the one-piece molded structure, and the overall hollow mesh structure increases the safety factor by 25%. This utility model uses ductile iron QT900-6, which is cast in one piece without heat treatment, reducing manufacturing costs. This utility model is a one-piece molded structure, which can connect multiple parts simultaneously through a single main structure, simplifying the assembly process, reducing production costs, improving assembly efficiency, and effectively improving the reliability and stability of the entire vehicle, meeting the needs of lightweight vehicle development.
