Description

Technical Field

[0001] This utility model relates to the field of railcar panel technology, specifically a stable-installing roof panel for a railcar. Background Technology

[0002] Rail vehicles include various types, such as subway, high-speed rail and light rail vehicles. The interior of the rail car is equipped with decorative ceiling panels. Currently, the existing decorative ceiling panels do not have their own expansion and contraction mechanisms. During the operation of the rail vehicle, a lot of stress will be generated. This stress can easily cause the ceiling panels to bend or be damaged, resulting in a short service life.

[0003] A search revealed a car body and its decorative roof panel with publication number CN207106501U. The roof panel includes a roof panel body and mounting profiles. The roof panel body includes an aramid honeycomb sandwich layer and prepreg layers located on both sides of the aramid honeycomb sandwich layer. This technical solution also suffers from the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a stable roof panel for a vehicle compartment to solve the problems mentioned in the background section.

[0006] Optionally, a motion box is provided at the gap between the center plate and the side plate, a motion plate is provided inside the motion box, and a connecting plate is fixedly connected to the side of the motion plate, and the side of the connecting plate is fixedly connected to the side plate.

[0007] Optionally, a groove is provided on the side of the center plate, and a slider is slidably connected to the inner wall of the groove. The side of the slider is fixedly connected to the motion box.

[0008] Optionally, a track is fixedly connected to the inner wall of the slide, and a spring is sleeved on the surface of the track.

[0009] Optionally, a telescopic rod is fixedly connected to the inner wall of the exercise box, and the end of the telescopic rod is fixedly connected to the exercise plate.

[0010] Optionally, a second spring is fitted onto the surface of the telescopic rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model utilizes the cooperation of a center plate, side plates, mounting blocks, motion boxes, motion plates, connecting plates, slides, sliders, tracks, spring one, telescopic rods, springs, elastic cloth, mounting strip one, and mounting strip two. During use, multiple mounting blocks are used to assemble the top plate with the vehicle frame, resulting in good installation stability. Furthermore, the top plate itself has the function of telescopic deformation and misalignment, which can effectively resist the stress during the operation of the rail vehicle, effectively preventing the top plate from bending or being damaged, and extending its service life.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6A stable roof panel for a carriage includes a central panel 1. Ten grooves 7 are formed on both sides of the central panel 1, with five grooves located on each side of the central panel 1. A track 9 is fixedly connected to the inner wall of each groove 7. A slider 8, a cylindrical rod, is slidably connected to the surface of the track 9. The front and rear sides of the slider 8 contact the front and rear sides of the inner wall of the groove 7, respectively. The track 9 prevents the slider 8 from detaching from the groove 7. The cylindrical rod does not restrict rotation, but the sides of the slider 8 contact the inner wall of the groove 7. Therefore, slider 8 will only move linearly up and down on the inner wall of slide groove 7. Slider 8 extends beyond slide groove 7. Every five sliders 8 are fixedly connected by a motion box 4. Spring 10 is sleeved on the surface of track 9. There are two springs 10 on the surface of track 9. One end of spring 10 is fixedly connected to the center plate 1, and the other end is fixedly connected to slider 8. The purpose of using spring 10 is to provide a reset force. That is, when an external force causes slider 8 to move on the surface of track 9, after the external force disappears, spring 10 will drive slider 8 to reset.

[0022] The motion box 4 is a box with an open bottom. A motion plate 5 is installed on its inner wall. Five telescopic rods 11 are fixedly connected to the side of the motion plate 5. The telescopic rods 11 can extend or retract. The end of the telescopic rod away from the motion plate 5 is fixedly connected to the inner wall of the motion box 4. The multiple telescopic rods 11 are designed to prevent the motion plate 5 from falling out of the motion box 4 and to limit the motion plate 5 to horizontal linear movement within the motion box 4. A second spring 12 is fitted on the surface of each telescopic rod 11. One end of the second spring 12 is fixedly connected to the motion plate 5, and the other end is fixedly connected to the inner wall of the motion box 4. The function of the second spring 12 is similar to that of the first spring 10. When the motion plate 5 moves within the motion box 4 due to external force, the second spring 12 will cause the motion plate 5 to return to its original position when the external force disappears.

[0023] A connecting plate 6 is fixedly connected to the vertical side of the motion plate 5 away from the telescopic rod 11. The side of the connecting plate 6 extends to the outside of the motion box 4 and is connected to a side plate 2. Three mounting blocks 3 with mounting holes are fixedly connected to the side of the side plate 2. By using screws or bolts through the mounting holes on the mounting blocks 3, the top plate can be assembled with the car frame. Since the slide groove 7 leaves space for the slider 8 to move up and down, the side plate 2 has a vertical misalignment range with the center plate 1. The interior of the motion box 4 also leaves space for the horizontal movement of the motion plate 5, so the side plate 2 has a range of horizontal distance variation with the center plate 1. After the mounting blocks 3 are assembled with the car frame, the distance and vertical position between the center plate 1 and the side plate 2 can be changed and reset. The stress generated during the operation of the railcar will not cause damage to the top plate.

[0024] The lower part of the center plate 1 faces the interior of the carriage, so the structure in the gap between the center plate 1 and the side plate 2 will affect the aesthetics. In this technical solution, an installation strip 14 is fixedly installed at the bottom of the center plate 1, and an installation strip 25 is fixedly installed at the bottom of the side plate 2. The installation strip 14 and the installation strip 25 are connected by an elastic cloth 13. The elastic cloth 13 should be dark-colored, such as black or dark blue. The elastic cloth 13 is elastic, so it will not affect the vertical misalignment of the center plate 1 and the side plate 2, nor will it affect the change of the horizontal distance between the center plate 1 and the side plate 2, thus ensuring aesthetics without affecting the movement of the structure.

[0025] In use, screws or bolts are used to pass through the mounting holes on the mounting block 3 to install the mounting block 3 onto the car frame, thus completing the assembly of the top plate. During the movement of the railcar, the entire car will generate some stress, the slider 8 can move on the surface of the track 9, the spring 10 will deform and return to its original position, and there is a vertical misalignment range between the center plate 1 and the side plate 2. The moving plate 5 will move on the inner wall of the moving box 4, the telescopic rod 11 and the second spring 12 will deform, and the second spring 12 can drive the moving plate 5 to return to its original position. There is a range of horizontal spacing variation between the center plate 1 and the side plate 2.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
