Abstract

Some embodiments of the present disclosure provide a roof component of a railway vehicle, and a railway vehicle. The roof component of a railway vehicle includes: two upper boundary beams, the two upper boundary beams being provided at an interval; a camber beam component, the camber beam component being provided between the two upper boundary beams; and a transitional structure, provided on the camber beam component, the transitional structure being connected with at least one of the two upper boundary beams. The technical solution of the present disclosure solves the problem in the conventional art of inconvenient connection between a camber beam component and an upper boundary beam, and a transitional structure of the present application facilitates processing and forming.

First claim

What is claimed is:

1. A roof component of a railway vehicle, comprising:
two upper boundary beams, the two upper boundary beams being provided at an interval; and
a camber beam component, the camber beam component being provided between the two upper boundary beams; and
a transitional structure, provided on the camber beam component, the transitional structure being connected with at least one of the two upper boundary beams;
wherein each of the two upper boundary beams comprises two first upper boundary beam segments and a second upper boundary beam segment connecting the two first upper boundary beam segments,
wherein a width of the first upper boundary beam segments gradually increases along a length of the first upper boundary beam segments in a direction from opposing ends of the railway vehicle to a middle of the railway vehicle; and
wherein a width of the second upper boundary beam segments is consistent along a length of the second upper boundary beam segments.

2. The roof component as claimed in claim 1 , wherein the camber beam component comprises:
a plurality of middle camber beams, each of the plurality of middle camber beams being connected with the second upper boundary beam segment; and
a plurality of end camber beams, each of the plurality of end camber beams being connected with a corresponding first upper boundary beam segment in the two first upper boundary beam segments,
wherein the plurality of end camber beams and the plurality of middle camber beams are provided along a length direction of each of the two upper boundary beams at an interval, and the transitional structure is provided on each of the plurality of middle camber beams.

3. The roof component as claimed in claim 2 , wherein the transitional structure is a transitional beam provided at one end of each of the plurality of middle camber beams.

4. The roof component as claimed in claim 3 , wherein the camber beam component further comprises an inserted-connected portion, a first end of the second upper boundary beam segment being inserted into the inserted-connected portion, wherein the inserted-connected portion is provided on the transitional beam or, the inserted-connected portion is provided between each of the plurality of middle camber beams and the transitional beam.

5. The roof component as claimed in claim 3 , wherein the transitional beam and each of the plurality of middle camber beams are an integrated molding structure.

6. The roof component as claimed in claim 4 , wherein a water groove is provided at a second end of the second upper boundary beam segment.

7. The roof component as claimed in claim 2 , wherein each of the plurality of end camber beams comprises:
two first end camber beam segments, the two first end camber beam segments being correspondingly connected with the two first upper boundary beam segments; and
a second end camber beam segment, used for connecting the two first end camber beam segments, each of the two first end camber beam segments being fixedly connected with the second end camber beam segment.

8. The roof component as claimed in claim 7 , wherein at least one of the two first upper boundary beam segments is fixedly connected with one of the two first end camber beam segments.

9. The roof component as claimed in claim 2 , wherein sections of the middle camber beams and/or the end camber beams are Z-shaped along a width direction of the roof component.

10. The roof component as claimed in claim 1 , further comprising a roof body, the camber beam component being used for supporting the roof body.

11. The roof component as claimed in claim 10 , wherein the roof body is a corrugated plate structure.

12. The roof component as claimed in claim 4 , wherein the transitional beam and each of the plurality of middle camber beams are an integrated molding structure.

13. The roof component as claimed in claim 3 , wherein sections of the middle camber beams and/or the end camber beams are Z-shaped along a width direction of the roof component.

14. The roof component as claimed in claim 4 , wherein sections of the middle camber beams and/or the end camber beams are Z-shaped along a width direction of the roof component.

15. The roof component as claimed in claim 2 , further comprising a roof body, the camber beam component being used for supporting the roof body.

16. The roof component as claimed in claim 3 , further comprising a roof body, the camber beam component being used for supporting the roof body.

17. The roof component as claimed in claim 4 , further comprising a roof body, the camber beam component being used for supporting the roof body.

18. A railway vehicle, comprising a roof component and a side wall component connected with the roof component, wherein the roof component is the roof component as claimed in claim 1 .

19. A railway vehicle, comprising a roof component and a side wall component connected with the roof component, wherein the roof component is the roof component as claimed in claim 2 .

20. A railway vehicle, comprising a roof component and a side wall component connected with the roof component, wherein the roof component is the roof component as claimed in claim 3 .
