Description

Technical Field

[0001] The utility model relates to a side roof plate of a rail transit vehicle, and belongs to the technical field of the installation structure of a decorative plate of a side roof plate inside a rail transit vehicle. Background Art

[0002] Rail transit vehicles are usually equipped with side roof panels on the side roofs to decorate the interior space and cover the side equipment. Figure 8 As shown, the side top plate of the prior art includes an inclined portion 9 connected to the top of the vehicle body and a horizontal portion 10 connected to the side wall of the vehicle body. The upper portion of the inclined portion 9 is connected to the top of the vehicle body through a hinge, and includes an interior trim panel 2. The side top plate 2 is extruded from an aluminum plate or aluminum profile, and is provided with bolt placement grooves for equipment and related locks.

[0003] The side top panel structure of the prior art has the following technical problems: first, the interior panel of the side top panel facing the interior of the car is usually paved with signs such as a subway map.

DETAILED DESCRIPTION

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0030] Example 1

[0031] like Figure 1-Figure 4 As shown, the side roof panel of the rail transit vehicle of this embodiment includes an inclined portion 9 connected to the top of the vehicle body and a horizontal portion 10 connected to the side wall of the vehicle body. The upper portion of the inclined portion 9 is connected to the top of the vehicle body through a hinge mounting seat 1, and a lock 4 is provided on the back side of the horizontal portion 10.

[0032] The inclined portion 9 includes an upper connection portion 3 hinged to the top of the vehicle body, a lower connection portion 8 fixedly connected to the horizontal portion 10, and an interior panel 2 disposed between the upper connection portion 3 and the lower connection portion 8; the interior panel 2 is plugged into the upper connection portion 3 and the lower connection portion 8. The upper connection portion 3 and the lower connection portion 8 are respectively provided with a first slide groove 11 and a second slide groove 12 extending along the length direction of the upper connection portion 3 and the lower connection portion 8, and the upper and lower sides of the interior panel 2 are respectively plugged into the first slide groove 11 and the second slide groove 12.

[0033] The upper and lower sides of the interior panel 2 are respectively provided with plug-in boards 21 extending into the first and second chutes 11 and 12 along the width direction of the interior panel 2; screws 5 extending into the first and second chutes 11 and 12 are provided on the back sides of the first and second chutes 12 for fastening the position of the interior panel 2, and the screws 5 are flat head screws. After the interior panel 2 is inserted into the first and second chutes 11 and 12 along the length direction of the side top plate, the screws 5 are tightened, and one end of the screws 5 extending into the first and second chutes 11 and 12 presses against the plug-in boards 21 to fix the position of the interior panel 2, so that the interior panel 2 presses against the inner walls of the first and second chutes 11 and 12, and the movement of the interior panel 2 is restricted.

[0034] In order to increase the friction between the interior panel 2 and the upper connection part 3 and the lower connection part 8 and prevent the surface of the interior panel 2 from being scratched, a filling layer 6 is provided on the back side of the interior panel 2 and between the interior panel 2 and the first slide groove 11 and the second slide groove 12. The filling layer 6 is made of a flexible material, and the interior panel is evenly adjusted between the upper connection part 3 and the lower connection part 8 and then glued and sealed. Glue seams are provided in the gaps between the interior panel 2 and the first slide groove 11 and the second slide groove 12 to fill the gaps.

[0035] The connecting member 7 includes a rib plate 71 arranged on the back side of the upper connecting portion 3 and the lower connecting portion 8. The upper and lower sides of the rib plate 71 are respectively connected and fixed to the upper connecting portion 3 and the lower connecting portion 8 by fasteners, and the fasteners are bolts. The rib plate 71 is a reinforcing rib connecting plate. In Example 1, the upper connecting portion 3 and the lower connecting portion 8 are separately made split structures. The upper connecting portion 3 and the lower connecting portion 8 need to be connected and fixed by the rib plate 71. The upper and lower ends of the rib plate 71 are respectively connected and fixed to the upper connecting portion 3 and the lower connecting portion 8 by fasteners, so that a stable integral structure is formed between the upper connecting portion 3, the interior panel 2, the lower connecting portion 8 and the horizontal portion.

[0036] Example 2

[0037] like Figure 6-Figure 7 As shown, different from Example 1, the connector 7 of this embodiment includes a connecting plate 72 arranged on the back of the upper connecting part 3 and the lower connecting part 8 and formed integrally with the upper connecting part 3 and the lower connecting part 8. The upper connecting part 3 and the lower connecting part 8 of Example 2 are not made separately, but are made into a whole by opening the aluminum profile. This method can achieve the effect and function of the utility model, and the advantages are strong integrity, good structural strength and rigidity, a larger contact surface when the interior trim panel 2 is plugged in, and stronger friction resistance.

[0038] In practical application, during assembly, the upper connection part 3 and the lower connection part 8 are firmly connected and pre-assembled into a whole by using the rib plate 71, and then the plug-in plates 21 on the upper and lower sides of the interior panel 2 are inserted into the stress-bearing part to wrap the adhesive filling layer 6 to protect it from external force extrusion during the plug-in process and avoid the interior panel 2 from cracking. Then the interior panel 2 is plugged into the first slide groove 11 and the second slide groove 12 of the upper connection part 3 and the lower connection part 8 from the side. At this time, the waist hole on the rib plate 71 can be appropriately adjusted according to the plug-in situation of the interior panel 2. After adjusting the upper and lower gaps, screw the screw 5 from the back to firmly clamp the interior panel 2 without sliding, and then glue the uniform gap in front. Finally, the hinge mounting seat 1 and the lock 4 are sequentially installed on the interface pre-opened on the upper connection part 3 and the lower connection part 8 to form the entire side top plate. The overall structure of the side top plate is reliable and the effect is beautiful. By adopting the plug-in of the interior panel and utilizing the changes of different materials and colors of the decorative panel, the visual effect in the passenger compartment is enhanced to achieve a better riding experience.

[0039] The assembled side top panels are connected to the beam structure on the top of the vehicle through the hinge mounting seat 1, and the lower part is locked to the lock tongue lap plate provided on the side of the vehicle through the lock 4, so as to realize the functions of decoration and opening for maintenance.

[0040] The contents explained in the above embodiments should be understood as these embodiments are only used to more clearly illustrate the present invention, and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art fall within the scope defined by the claims attached to this application.
