Description

Technical Field

[0001] The present application relates to the technical field of commercial vehicle cab upper structures, and in particular to a commercial vehicle high-top cab roof beam assembly and a commercial vehicle high-top cab. Background Art

[0002] The cab of a commercial vehicle is not only the driver's workplace, but also an important part of the entire vehicle. The cab of a commercial vehicle should provide convenient working conditions for the driver and comfortable riding conditions for the passengers, protecting them from vibration, noise, exhaust gas during driving and the impact of harsh weather conditions.

[0003] The general cab includes windows, doors, cockpit, etc. The commercial vehicle cab has several shapes, such as high roof, low roof, pointed head, etc. The commercial vehicle cab is one of the most important parts of the commercial vehicle, and its design will directly affect the performance and safety of the commercial vehicle.

[0004] In the related art, see Figure 5 As shown in the figure, the skylight beam of the cab of a commercial vehicle usually adopts a cross-shaped beam structure, and the skylight beam extends out of the overlap structure to connect with the bracket beam. The bracket beam and the skylight beam are overlapped and welded to form a "J"-shaped structure, which ensures the connection strength between the skylight beam assembly and the brackets around the roof, and ensures the structural rigidity of the roof assembly when it is subjected to top pressure and torsion.

[0005] However, when the skylight beam is connected to the bracket, the overlap section is a "J"-shaped section, the overlap strength is low, and the overall torsion and connection strength performance do not meet the requirements of harsh working conditions. In order to ensure the overlap strength, the overlap area of ​​the skylight beam and the bracket needs to be increased. The corresponding stamping blank area of ​​the skylight beam will increase, and most of the increased blanks will be discarded during the stamping process, resulting in a large amount of material waste and increased costs.

[0006] In addition, the existing technical solutions are relatively simple. When the joint strength can be guaranteed, the structure of the skylight beam will not be significantly changed, resulting in a low degree of product modularity. When the product is adaptively developed or a new model is developed, the development cost is high. Summary of the invention

[0007] The embodiment of the present application provides a roof beam assembly of a commercial vehicle high-top cab and a commercial vehicle high-top cab, so as to solve the problem in the related art that in order to ensure the lap strength, the lap area of ​​the criss-cross beam and the lap edge of the bracket needs to be increased, and most of the increased blanks will be discarded during the stamping process, resulting in a large amount of material waste and increased costs.

[0038] See also Figures 1 to 3 As shown, the first aspect of the embodiment of the present application provides a roof beam assembly of a high-top cab of a commercial vehicle, comprising:

The length of the skylight frame 1 is 1400-1500 mm, more preferably 1450 mm, and the width of the skylight frame 1 is 900-1000 mm, more preferably 960 mm.

[0040] The bracket beam includes a frame longitudinal beam 5 located at the front and rear ends of the sunroof frame 1, and a frame cross beam 3 located at the left and right sides of the sunroof frame 1. The frame longitudinal beam 5 and the frame cross beam 3 are both fixedly connected to the sunroof frame 1 to support the sunroof frame 1 on the top of the cab, so as to provide positioning and support for the top outer cover on the top of the cab.

[0041] The reinforcing plate includes an upper reinforcing plate 2 and a lower reinforcing plate 4 for fixing the skeleton longitudinal beam 5 and the skeleton cross beam 3 on the skylight frame 1. The upper reinforcing plate 2 and the lower reinforcing plate 4 are respectively located on the top surface and the bottom surface of the skylight frame 1 to connect the skeleton cross beam 3, the skeleton longitudinal beam 5 and the skylight frame 1 into a whole.

[0042] The sunroof frame 1 of the roof beam assembly of the high-top cab of a commercial vehicle in the embodiment of the present application is a rectangular frame structure formed by integrally stamping a steel plate, and the skeleton longitudinal beam 5 and the skeleton cross beam 3 are welded to the sunroof frame 1 by using an upper reinforcing plate 2 and a lower reinforcing plate 4, thereby improving the structural strength of the skeleton longitudinal beam 5 and the skeleton cross beam 3 and the sunroof frame 1.

[0043] The overlap between the skeleton longitudinal beam 5 and the skeleton cross beam 3 and the skylight frame 1 forms a closed cavity structure, which increases the local structural strength and torsional strength. Compared with the traditional cross beam, the structure of the skylight frame 1 reduces the material waste caused by meeting the overlap requirements with the bracket beam and reduces the production cost.

The overlapping structure extending around the skylight beam to connect with the bracket beam in the related art is eliminated, the blank area does not need to be increased, and excessive waste is avoided during the stamping process, thereby saving material costs.

[0047] The front cross beam 11, the left longitudinal beam 13, the rear cross beam 12 and the right longitudinal beam 14 are integrally stamped and formed structures, and the cross sections of the front cross beam 11, the left longitudinal beam 13, the rear cross beam 12 and the right longitudinal beam 14 are all "J"-shaped structures with the opening facing upward. The integrally stamped and formed skylight frame 1 has good structural strength, which improves the compressive, bending and torsional strengths of the cab. At the same time, the cross sections of the front cross beam 11, the left longitudinal beam 13, the rear cross beam 12 and the right longitudinal beam 14 are all "J"-shaped structures with the opening facing upward, which are convenient for welding and connecting with the outer cover to form a structurally stable cavity structure, further improving the structural stability of the cab.

Thus, the connection between the frame cross beam 3 and the frame longitudinal beam 5 and the skylight frame 1 forms a stable cavity structure, which significantly improves the connection strength and torsional strength of the roof beam assembly.

[0054] The upper reinforcing plate 2 and the lower reinforcing plate 4 are welded to the skeleton cross beam 3, and the welding points are not directly welded to the outer covering panel, thereby avoiding the influence of the welding points on the appearance, and at the same time avoiding the welding point defects and appearance defects caused by the mismatch between the upper reinforcing plate 2 and the lower reinforcing plate 4 and the outer covering arc surface after welding.
