[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0026] like Figures 1 to 4 As shown, this embodiment discloses an integrated staircase decoration for a bus, which is integrally formed by blister or fiberglass material, and the outer surface is covered with Nappa leather (not shown) for softening treatment.

[0027] The decorative part includes a main body 1 and a connecting part 2 located above the main body 1. The connecting part 2 smoothly transitions with the main body 1. The main body 1 is divided into a first part 11 for shielding stairs and a second part 12 inclined from the back to the front toward the aisle for shielding the cab. The intersection of the second part 12 and the first part 11 adopts a third fillet 13 for smooth transition. The first part 11 has a rear edge 14, a lower edge and a bevel 15. The rear edge 14 is vertically arranged, and the lower edge is horizontally arranged. The bottom end of the bevel 15 is connected to the upper end of the rear edge 14 through a first fillet 16, and the upper end of the bevel 15 is connected to the rear end of the connecting part 2 through a second fillet 17 (the second fillet 17 in the attached figure of this embodiment is a concave fillet, and a convex fillet connection may also be adopted depending on the length of the connecting part 2). A groove-shaped folded edge 18 for covering the staircase frame is continuously provided from the rear end of the connecting part 2 along the bevel 15 to the lower end of the lower edge. The grooved folded edge 18 is connected to the stair frame by screws, air nails, welding, etc., and the installation trace is located on the side or inside of the decorative piece, and is not exposed on the front of the decorative piece, so it is more beautiful. The decorative piece covers the stair frame in an integrated manner, does not require additional closing strips, reduces the number of parts, and is integrated with the staircase in appearance. In addition, the second part 12 is integrally formed with the first part 11, which further shows the integrity of the decorative piece and the simplicity of the coach aisle wall structure.

[0028] The connecting portion 2 and the main body 1 are smoothly transitioned. Specifically, the connecting portion 2 is convex or concave relative to the main body 1, the connecting portion 2 and the main body 1 are smoothly transitioned through rounded corners, or the connecting portion 2 and the main body 1 are flush with each other.

[0029] The first part 11 is provided with a first sink 19, the height of the edge of the first sink 19 is higher than the height of the edge of the decorative piece, and the portion between the edge of the decorative piece and the edge of the first sink 19 has no sharp edges and a smooth transition, so that the surface of the first part 11 avoids obvious sharp edges and prevents bumps. In a specific structure, the second fillet 17, the bevel 15, the first fillet 16 and the rear edge 14 are connected to the edge of the first sink 19 through a continuous and smooth curved surface, or a bevel, or a combination of a curved surface and a bevel. The lower edge of the first sink 19 can extend to be flush with the lower edge of the first part 11, or it can be at a certain distance from the lower edge of the first part 11. If there is a certain distance between the lower edge of the first sink 19 and the lower edge of the first part 11, the second fillet 17, the bevel 15, the first fillet 16, the rear edge 14 and the lower edge of the first part 11 are connected to the edge of the first sink 19 through a continuous and smooth curved surface, or a bevel, or a combination of a curved surface and a bevel, so that the surface lines of the first part 11 other than the first sink 19 are smooth and anti-collision.

[0030] The height of the edge of the first sunken platform 19 is higher than the height of the edge of the decorative part, so the edge of the decorative part can be designed to be blunt angled to make the edge softer. The corners are connected by multiple fillets, and the surface of the protruding part other than the first sunken platform 19 is set as a curved surface or an inclined surface, so that the surface line of the decorative part is soft and avoids collision with passengers.

[0031] The first sunken platform 19 is partially concave to form a second sunken platform 110, and the middle of the second sunken platform 110 is penetrated to form an inspection port 111, and the inspection port 111 is provided with an inspection cover 3. The bottom of the second sunken platform 110 is formed along the periphery of the inspection port 111 to form a stopper 112 for limiting the inspection cover 3, and the stopper 112 is connected to the stair frame, and the inspection cover 3 matches the second sunken platform 110 and covers the stopper 112. The stopper 112 is connected to the stair frame by screws, air nails, welding, etc., and then the inspection cover 3 is used to cover the stopper 112, thereby hiding the installation traces on the stopper 112, which is more beautiful.

[0032] The surface of the second portion 12 is partially concave to form a third long sunken platform 113. The third sunken platform 113 is used to install a U-shaped handrail, which reduces the height of the U-shaped handrail protruding from the surface of the decorative component to avoid hindering passengers from walking.

[0033] The side walls of the first sunken platform 19, the second sunken platform 110 and the third sunken platform 113 are all inclined, which is conducive to blunting the corners where the sunken platforms meet the surfaces of the decorative parts to avoid collisions. The surface of the decorative part is provided with concave and convex, not flat, which is conducive to improving the strength of the decorative part.

[0034] The front edge and the lower edge of the main body 1 are provided with folded edges inwardly to prevent the edges from being exposed and bumped.

[0035] As described above, the embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model. Therefore, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the protection scope of the utility model.
