Technical Field

[0001] This utility model relates to the field of drag-reducing carriage technology, specifically a lightweight, streamlined drag-reducing carriage. Background Technology

[0002] Carriages are almost always found on means of transportation. Trains have carriages, and some cars do too. Traditional freight cars or logistics vehicles mostly use ordinary steel plates, PVC plastic, or galvanized steel plates with polyurethane interlayer as the carriage material.

[0003] Currently, due to the heavy weight of the carriages being manufactured, most of them are boxy in shape, resulting in a rather rigid and unsightly overall design that lacks a sense of streamline. This leads to problems such as poor aesthetics and drag reduction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lightweight, streamlined drag-reducing carriage, which solves the problem mentioned in the background art that current carriages are heavy, mostly square in shape, and have a rigid and unsightly appearance due to their lack of streamlined design, resulting in poor drag reduction performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight, streamlined, drag-reducing carriage, comprising a roof panel and a carbon fiber composite frame, characterized in that: the roof panel is fixedly connected to the carbon fiber composite frame; two side panels, a bottom panel, and a front panel are fixedly installed on the outer surface of the carbon fiber composite frame; a sealing mounting bracket is fixedly installed on the outer surface of the carbon fiber composite frame away from the front panel; two hinges are fixedly installed on the outer surface of the sealing mounting bracket; door panels are fixedly installed at the output ends of the two hinges; and the outer surfaces of the two door panels are sealed together.

[0006] Preferably, the top plate, front plate, bottom plate, and two bottom plates are all made of a combination and fixed with a polypropylene honeycomb plate and two aluminum alloy plates sandwiched together.

[0007] Preferably, the front panel is arc-shaped, and the carbon fiber composite frame is smooth.

[0008] Preferably, handles are fixedly installed on the outer surfaces of both door panels, the two door panels are rotatably connected to the two side panels and the sealing mounting bracket, and the intersection of the door panels and the side panels is a smooth arc.

[0009] Preferably, the outer surfaces of the top plate, front plate, bottom plate, and the two bottom plates are all provided with a waterproof and corrosion-resistant coating, and mounting components are fixedly installed on the outer surface of the bottom plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This lightweight, streamlined drag-reducing carriage uses a carbon fiber composite frame to assemble the main components of the carriage, including the top panel, front panel, bottom panel, and two bottom panels. While ensuring the stability of the main body of the carriage, it gives the carriage an arrow-like appearance, effectively reducing aerodynamic drag. At the same time, the outer surfaces of the two door panels are sealed together. The door panel sealing design reduces the overall drag coefficient, thereby making the carriage more streamlined, improving its aesthetics and drag reduction.

[0012] 2. This lightweight, streamlined drag-reducing cargo box is constructed by using polypropylene honeycomb panels and two aluminum alloy plates sandwiched together for the top, front, and bottom panels. The polypropylene honeycomb panel cargo box is significantly lighter than traditional steel boxes, making it suitable for standard load transportation. It can save fuel per year of operation, thus achieving the effect of reducing resource consumption while maintaining robustness. Attached Figure Description

[0019] Example 1:

[0020] Please refer to Figures 1-4.

[0021] A lightweight, streamlined, drag-reducing car body includes a roof panel 1 and a carbon fiber composite frame 2. The roof panel 1 is fixedly connected to the carbon fiber composite frame 2. Two side panels 3, a bottom panel 5, and a front panel 4 are fixedly installed on the outer surface of the carbon fiber composite frame 2. A sealing mounting bracket 6 is fixedly installed on the outer surface of the carbon fiber composite frame 2 away from the front panel 4. Two hinges 7 are fixedly installed on the outer surface of the sealing mounting bracket 6. Door panels 8 are fixedly installed at the output ends of the two hinges 7. The outer surfaces of the two door panels 8 are sealed together.

[0022] Specifically, the main components of the carriage, namely the top plate 1, front plate 4, bottom plate 5, and two bottom plates 5, are assembled using a carbon fiber composite frame 2. This ensures the stability of the main body of the carriage while giving it an arrow-like appearance, effectively reducing aerodynamic drag. At the same time, the outer surfaces of the two door panels 8 are sealed together. The sealed design of the door panels 8 reduces the overall drag coefficient, thereby making the carriage more streamlined, improving its aesthetics, and reducing drag.

[0023] In the embodiment: the front panel 4 is arc-shaped, and the carbon fiber composite frame 2 is smooth.

[0024] Specifically, because the front panel 4 is curved, it effectively reduces aerodynamic drag and ensures high-speed operation stability. The carbon fiber composite frame 2 is smooth and uses carbon fiber composite material for the carriage, which reduces weight and achieves higher energy efficiency, increasing the energy saving rate of the air conditioning system by 25%.

[0025] In the embodiment: handles 9 are fixedly installed on the outer surfaces of the two door panels 8, the two door panels 8 are rotatably connected to the two side panels 3 and the sealing mounting bracket 6, and the intersection of the door panel 8 and the side panel 3 is a smooth arc.

[0026] Specifically, because handles 9 are fixedly installed on the outer surfaces of both door panels 8, and the two door panels 8 are rotatably connected to the two side panels 3 and the sealing mounting bracket 6, and the intersection of the door panel 8 and the side panel 3 is a smooth arc, the airflow direction is optimized and the generation of vortices is reduced. Combined with the sealing design of the side door and the rear door, the overall wind resistance coefficient is reduced by 15% to 20%.

[0027] Working principle: Because the top plate 1 is fixedly connected to the carbon fiber composite frame 2, two side plates 3, a bottom plate 5, and a front plate 4 are fixedly installed on the outer surface of the carbon fiber composite frame 2. At the same time, a sealing mounting bracket 6 is fixedly installed on the outer surface of the carbon fiber composite frame 2 away from the front plate 4. In addition, two hinges 7 are fixedly installed on the outer surface of the sealing mounting bracket 6. Door panels 8 are fixedly installed at the output ends of the two hinges 7, and the outer surfaces of the two door panels 8 are sealed together. The carbon fiber composite frame 2 assembles the main components of the carriage, the top plate 1, the front plate 4, the bottom plate 5, and the two bottom plates 5. While ensuring the stability of the main body of the carriage, it makes the carriage have the appearance of an arrow released from a bow, effectively reducing aerodynamic drag. At the same time, the outer surfaces of the two door panels 8 are sealed together. The sealing design of the door panels 8 reduces the overall wind resistance coefficient. Compared with related technologies, the lightweight streamlined drag-reducing carriage provided by this utility model has the following beneficial effects: thereby achieving the effect of making the carriage more streamlined, improving the aesthetics of the carriage, and reducing drag.

The polypropylene honeycomb panel 10 cargo box is significantly lighter than the traditional steel box, making it suitable for standard load transportation and saving fuel per year of operation. This achieves the effect of being sturdy while reducing resource consumption.
