[0001] The utility model relates to the technical field of vehicle parts, and particularly relates to a high-strength cage-type aluminum alloy driver's cab skeleton structure. Background Art

[0002] The driver's cab skeleton is mainly located at the front part of the rail vehicle, providing installation supports for the outer skin, interior parts, electrical components, etc. of the front part. It provides rigid support during the high-speed operation of the vehicle, and well ensures the deformation of the outer cover caused by wind resistance during the driving process of the vehicle. At present, most of the driver's cab skeletons are made of stainless steel or carbon steel structures, which are connected to the vehicle body by bolts or welding. While ensuring the stiffness, the overall vehicle body weight is relatively large. Therefore, the above problems need to be solved. Content of the Utility Model

[0003] The purpose of the utility model is to provide a high-strength cage-type aluminum alloy driver's cab skeleton structure to overcome the above defects in the prior art.

[0004] A high-strength cage-type aluminum alloy driver's cab skeleton structure includes main beams, rear connecting plates and bottom connecting plates. The bottom connecting plate is of a "U" shape with the opening facing backward, and several main beams are arranged on the bottom connecting plate. The rear connecting plate is of a "U" shape with the opening facing downward, and the rear connecting plate is respectively connected to the main beams and the bottom connecting plate. There are several connecting pipes between the rear connecting plate and the main beams.

[0005] Preferably, the number of the main beams is three or four.

[0006] Preferably, the rear connecting plate and the bottom connecting plate are rigidly connected to the vehicle body by welding or bolts.

[0007] Preferably, the main beams, rear connecting plates, bottom connecting plates and connecting pipes are all made of fixed-drawing aluminum profiles.

[0008] Preferably, a reinforcing plate is provided between the rear connecting plate and the bottom connecting plate.

[0009] The utility model has the following advantages:

[0010] The utility model adopts an aluminum alloy welded cage-type skeleton with strong overall stiffness. This design structure uses aluminum profiles, and the stiffness of the skeleton can be improved by adjusting the cross-sectional dimensions and shapes. While ensuring rigid support for the whole vehicle, it has a lighter mass of the front part skeleton, improving the carrying capacity of the whole vehicle. The aluminum alloy driver's skeleton has strong anti-corrosion performance, and the product does not need surface treatment after welding, avoiding the use of paint coatings.

[0016] The following is a further detailed description of the specific embodiments of the present utility model with reference to the accompanying drawings and through the description of the embodiments, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present utility model.

[0017] As Figure 1-4 shown, the present utility model provides a high-strength cage-type aluminum alloy driver's cab skeleton structure, including a main beam 2, a rear connecting plate 3 and a bottom connecting plate 1. The bottom connecting plate 1 is of a "U" - shaped structure with the opening facing backward. A plurality of main beams 2 are provided and arranged on the bottom connecting plate 1. The rear connecting plate 3 is of a "U" - shaped structure with the opening facing downward. The rear connecting plate 3 is respectively connected to the main beam 2 and the bottom connecting plate 1. A plurality of connecting pipes 4 are provided between the rear connecting plate 3 and the main beam 2. At the same time, the main beam 2, the rear connecting plate 3, the bottom connecting plate 1 and the connecting pipes 4 are all made of fixed - pull aluminum profiles, so as to improve the overall stiffness of the skeleton.

[0018] It should be noted that three or four main beams 2 are designed in the height direction of the driver's skeleton, and other small - size profiles are respectively used to make connection supports between the rear connecting plate 3, the bottom connecting plate 1 and the main beam 2.

[0019] In addition, the rear connecting plate 3 and the bottom connecting plate 1 are rigidly connected to the vehicle body by welding or bolts.

[0020] In addition, a reinforcing plate 5 is provided between the rear connecting plate 3 and the bottom connecting plate 1 to enhance the strength between the rear connecting plate 3 and the bottom connecting plate 1.

[0021] At the same time, openings are made on the main beam 2, the rear connecting plate 3, the bottom connecting plate 1 and the connecting profiles. Considering the hardness of the aluminum profile material, bushings and bolts can be riveted at the corresponding positions on the side wall of the profile to improve the repeated use of assembly, and the riveted bushings and bolts are connected to the interior or exterior cover of the driver's cab.

[0022] In summary, the utility model adopts aluminum alloy welded cage frame with strong overall rigidity. The design structure adopts aluminum profiles and can improve the rigidity of the frame by adjusting the cross-sectional size and shape. While ensuring the rigid support for the whole vehicle, it has a lighter front frame mass and improves the carrying capacity of the whole vehicle.
