Description

Technical Field

[0001] This utility model relates to a layered composite frame for hydrogen fuel cell commercial vehicles, belonging to the field of new energy vehicles. Background Technology

[0002] With the development of new energy vehicles, the requirements for the integration of systems such as control systems, cooling systems, and electrical systems are constantly increasing. The design, management, and assembly of subsystems are quite difficult, and a combined frame needs to be designed to integrate the relevant components of the above systems.

[0003] Currently, the space utilization of the vehicle chassis is insufficient, and the layout of pipelines and cables is rather chaotic. It is necessary to design and develop a layered composite frame that integrates the steering system, air conditioning system, cooling system, control system and related components, while providing fixed points for the laying and layout of pipelines and cables, thereby improving the utilization rate of the vehicle chassis space. Utility Model Content

[0004] The purpose of this utility model is to provide a layered combination frame that is easy to install, providing assembly space for the relevant components of the above system, simplifying the frame structure and reducing the frame weight while ensuring strength.

[0005] This utility model is achieved through the following technical solution: A layered composite frame for hydrogen fuel cell commercial vehicles is disclosed. The main beams of the three-layer main body of the composite frame are all made of square steel 1 and rectangular steel 6. The main beams of square steel 1 and rectangular steel 6 are welded and fixed between each other and between layers using channel steel 2. At the connection positions between layers, T-shaped reinforcing plates 3, L-shaped reinforcing plates 4, and cross-shaped reinforcing plates 9 are welded according to the connection structure. Reinforcing angle steel 7 is welded at the right-angle connection positions. The bottom layer extends forward and is welded with mounting brackets 10. The space between the second and top layers is provided with cable brackets 8 for fixing cooling system pipes and high-voltage wiring harnesses. According to the arrangement requirements of cooling system pipes and high-voltage wiring harnesses, clamp fixing points are set or welding fixing brackets are used. The bottom layer is provided with a mounting base plate 5 for installation with the vehicle chassis.

[0006] This utility model's modular frame is constructed using welding technology, resulting in a robust structure. Its layered design facilitates assembly and maintenance, and allows for a more rational pipeline layout. The modular frame integrates a cooling water pump, air conditioning compressor, power steering pump, multi-function controller, and VCU controller, improving chassis space utilization and overall vehicle assembly efficiency. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a diagram showing the installation of components. Detailed Implementation

[0008] like Figure 1 ,2 As shown, the layered composite frame of this utility model consists of three layers. The two ends of the second layer are the vehicle frame fixing points, so the second layer is used as the design basis. The bottom layer is used to install the air conditioning compressor 13 and the power steering pump 16. Considering the layout of the cooling system, the bottom layer extends forward and welds the mounting bracket 10 to fix the cooling water pump 17. The top layer is used to fix the multi-function controller 11. The space between the second layer and the top layer is mainly used to fix the VCU controller 14, and at the same time provides fixing points 12 for cooling system pipes and fixing points 15 for high-voltage wiring harnesses.

[0009] Specifically, the main beams of the three-layer composite frame are all made of square steel 1 and rectangular steel 6. The square steel 1 and rectangular steel 6 of the main beams are welded and fixed to each other and to each layer using channel steel 2. At the same time, T-shaped reinforcing plates 3, L-shaped reinforcing plates 4 and cross-shaped reinforcing plates 9 are welded at the connection positions between layers according to the connection structure. Reinforcing angle steel 7 is welded at the right-angle connection positions. The bottom layer extends forward and is welded with mounting brackets 10. The space between the second and top layers is provided with cable brackets 8 for fixing the cooling system pipes and high-voltage wiring harnesses. According to the arrangement requirements of the cooling system pipes and high-voltage wiring harnesses, clamp fixing points are set or welding fixing brackets are used. The bottom layer is provided with a mounting base plate 5 for installation with the vehicle chassis.

[0010] The main beam of this composite frame uses square steel, the main body structure uses channel steel, and the reinforcing parts use angle steel, cross-shaped and T-shaped steel plates. It is welded as a whole, with low material cost, simple process, reliable strength, and uniform quality distribution in the layered design.
