Description

Technical Field

[0001] This application relates to the field of through-passage technology, and more specifically, to a roof plate mechanism for vehicle through-passage. Background Technology

[0002] The train passageway is an important component connecting the various carriages of a train. It mainly consists of folding canopies, ramps, side guards, and roof panels. The main functions of the passageway include windproofing, rainproofing, sound insulation, and heat insulation, ensuring the safe passage of passengers between different carriages.

[0003] In related technologies, in order to solve the problem of roof panel assemblies being able to adapt to different installation heights, for example, the prior art patent with publication number CN215752375U provides a roof panel assembly for a through passage, a through passage and a vehicle including the same. The device includes a connecting beam and at least one connecting block connecting the connecting beam to the intermediate frame. The height or size of the connecting block can be adjusted or can be selected from multiple sizes to adapt to different requirements for the height of the roof panel assembly.

[0004] Although the existing technical solutions mentioned above can achieve the effect of adapting the top plate assembly to different installation heights by changing or selecting connecting blocks of different heights, in actual use, it is necessary to pre-customize connecting blocks of the corresponding height according to the required height of the through passage top plate. Therefore, when installing the top plate assembly, it is necessary to prepare the connecting blocks in advance, which is relatively troublesome and not convenient for the rapid installation of the top plate assembly.

[0005] In view of this, we propose a roof plate mechanism for vehicle passageways. Utility Model Content

[0006] The purpose of this application is to provide a roof plate mechanism for vehicle passageways, which can effectively solve the problem in the prior art that the preparation work of making connecting blocks in advance is required when installing roof plate components, which is relatively troublesome and inconvenient for the rapid installation of roof plate components.

[0007] This application provides a roof plate mechanism for a vehicle passageway, comprising:

[0008] The fixed top plate is installed on top of the fixed frame;

[0009] The middle top plate is installed on top of the middle frame;

[0010] An adjustment component is used to adjust the installation height of the fixed top plate and the intermediate top plate relative to the fixed frame and the intermediate frame;

[0011] The adjustment components are provided in three ways, corresponding to the two fixed frames and one intermediate frame of the through channel. Each adjustment component includes two symmetrically arranged support rods and a bolt head for driving the two support rods to rotate. The top of the fixed top plate and the intermediate top plate are provided with two symmetrically arranged support rods, and the bottom of the fixed top plate and the intermediate top plate are rotatably provided with bolt heads.

[0012] As an optional solution to the technical solution of this application, the adjustment component further includes a guide groove, a bidirectional lead screw is rotatably arranged inside the guide groove, two sliders are symmetrically arranged outside the bidirectional lead screw, the two sliders are slidably arranged inside the guide groove, the sliders are rotatably connected to one end of the support rod, the bidirectional lead screw rotates under the drive of the bolt head, and the other end of the support rod is connected to the fixed frame or the intermediate frame through an outer corner bolt.

[0013] As an optional solution to the technical solution of this application, a transmission box is provided on the outside of the bidirectional lead screw, the transmission box is fixedly installed inside the guide groove, and a bolt head is rotatably provided at the bottom of the transmission box.

[0014] As an optional solution to the technical solution of this application, a base plate is fixedly provided at the bottom of the guide groove, and a slide rail is fixedly provided at the top of the base plate parallel to the axial direction of the bidirectional lead screw;

[0015] The top of the fixed top plate and the intermediate top plate are respectively fixedly provided with sliding plate A and sliding plate B. Sliding plate A and sliding plate B are slidably connected to the corresponding slide rails. The bottom of the fixed top plate and the intermediate top plate are respectively provided with strip holes A and strip holes B for the corresponding bolt heads. The size of the bottom plate is larger than the size of strip holes A and strip holes B.

[0016] As an optional solution of the technical solution in this application, a reinforcing plate is fixedly installed on the top of the fixed top plate, and the fixed top plate is inclined upward on the side near the middle top plate; transition plates are rotatably installed on both sides of the middle top plate, and the transition plates are all located on the top of the fixed top plate and inclined downward; a wear plate is installed between the transition plate and the fixed top plate, and the wear plate is fixedly installed at the bottom of the transition plate.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] (1) This application uses an adjustment component to adjust the installation height of the fixed top plate and the intermediate top plate. During adjustment, it is only necessary to rotate the bolt heads at the bottom of the fixed top plate and the intermediate top plate to drive the two support rods to rotate, so that the support rods can adjust the installation height of the fixed top plate and the intermediate top plate by changing the angle. Therefore, it effectively solves the problem that the preparation work of making connecting blocks in advance is required when installing the top plate assembly, which is more troublesome and not convenient for the quick installation of the top plate assembly. Thus, it achieves the effect of easy adjustment of the installation height when installing the top plate mechanism.

[0020] (2) By symmetrically setting two support rods on the fixed top plate and the intermediate top plate, the processing accuracy of the bolt holes on the inner side of the fixed frame and the intermediate frame can be reduced when the fixed top plate and the intermediate top plate are installed corresponding to the fixed frame and the intermediate frame, respectively. That is, it is only necessary to ensure that they are level, and there is no need to precisely control the position of the bolt holes. At the same time, the installation difficulty of the fixed top plate and the intermediate top plate is reduced, and the use is more flexible. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1-4 This application discloses a roof plate mechanism for a vehicle passageway, including a fixed roof plate 1, an intermediate roof plate 2, and an adjustment assembly 3. The fixed roof plate 1 is installed on the top of a fixed frame 100; the intermediate roof plate 2 is installed on the top of an intermediate frame 200; the adjustment assembly 3 is used to adjust the installation height of the fixed roof plate 1 and the intermediate roof plate 2 relative to the fixed frame 100 and the intermediate frame 200; wherein, three adjustment assemblies 3 are provided for the two fixed frames 100 and one intermediate frame 200 of the passageway, and each adjustment assembly 3 includes two symmetrically arranged support rods 31 and a bolt head 32 for driving the two support rods 31 to rotate; the top of the fixed roof plate 1 and the intermediate roof plate 2 are each provided with two symmetrically arranged support rods 31, and the bottom of the fixed roof plate 1 and the intermediate roof plate 2 are each rotatably provided with a bolt head 32.

[0031] By setting the bolt head 32 at the bottom of the fixed top plate 1 and the intermediate top plate 2, when installing the fixed top plate 1 and the intermediate top plate 2, the support rods 31 at the top of the fixed top plate 1 and the intermediate top plate 2 are connected to the fixed frame 100 and the intermediate frame 200 respectively. Finally, by rotating the bolt head 32 at the bottom of the fixed top plate 1 and the intermediate top plate 2, the two symmetrically arranged support rods 31 are driven to rotate synchronously, so that the included angle between the two support rods 31 changes and the support height of the corresponding fixed top plate 1 and intermediate top plate 2 is changed. Therefore, it is not necessary to pre-determine the connecting parts according to the installation height, and the adjustment can be achieved by rotating the bolt head 32, making the installation and adjustment work more convenient.

[0032] Specifically, in order to realize the driving function of bolt head 32 on support link 31, refer to Figure 3 and Figure 4 The adjusting assembly 3 also includes a guide groove 33. A bidirectional lead screw 34 is rotatably mounted inside the guide groove 33. Two sliders 35 are symmetrically mounted outside the bidirectional lead screw 34. The two sliders 35 are slidably mounted inside the guide groove 33. One end of the sliders 35 is rotatably connected to one end of the support rod 31. The bidirectional lead screw 34 rotates under the drive of the bolt head 32. The other end of the support rod 31 is connected to the fixed frame 100 or the intermediate frame 200 through an external angle bolt 37. A transmission box 36 is mounted outside the bidirectional lead screw 34. The transmission box 36 is fixedly mounted inside the guide groove 33. The bolt head 32 is rotatably mounted at the bottom of the transmission box 36.

[0033] By using a wrench to rotate the bolt head 32, the bolt head 32 drives the bidirectional lead screw 34 inside the guide groove 33 to rotate via the transmission box 36. When the bidirectional lead screw 34 rotates, the distance between the two sliders 35 is adjusted synchronously, causing the two sliders 35 to drive the ends of the support connecting rods 31 to slide, thereby changing the included angle between the two support connecting rods 31. This allows for the adjustment of the distance between the fixed top plate 1 and the fixed frame 100, as well as between the intermediate top plate 2 and the intermediate frame 200. The transmission box 36 transmitting the driving force of the bolt head 32 to the bidirectional lead screw 34 is existing technology and will not be described in detail here.

[0034] To improve the flexibility of the fixed top plate 1 and intermediate top plate 2 during installation with the fixed frame 100 and intermediate frame 200, refer to Figure 2 and Figure 3 A base plate 38 is fixedly installed at the bottom of the guide groove 33, and a slide rail 39 is fixedly installed at the top of the base plate 38 parallel to the axial direction of the double-acting screw 34. Slide plates A15 and B24 are fixedly installed at the top of the fixed top plate 1 and the intermediate top plate 2, respectively. Slide plates A15 and B24 are slidably connected to the corresponding slide rails 39. The bottom of the fixed top plate 1 and the intermediate top plate 2 are respectively provided with strip holes A11 and B22 for the corresponding bolt heads 32. The size of the base plate 38 is larger than the size of the strip holes A11 and B22.

[0035] In actual use, the bolt holes on the fixed frame 100 and the intermediate frame 200 may be misaligned. After the other ends of the two support rods 31 are connected to the fixed frame 100 and the intermediate frame 200 through the external angle bolts 37, there will be a misalignment between the fixed top plate 1 and the fixed frame 100, and between the intermediate top plate 2 and the intermediate frame 200. This results in a high requirement for the positional accuracy of the bolt holes on the outside of the fixed frame 100 and the intermediate frame 200. However, the sliding rail 39 is designed to slide in cooperation with the sliding plates A15 and B24 on the top of the fixed top plate 1 and the intermediate top plate 2, thereby enabling the support rods to slide smoothly. 31 can be slidably adjusted along the axial direction of the bidirectional screw 34 on the top of the fixed top plate 1 and the intermediate top plate 2, so as to adjust the relative position of the fixed top plate 1 and the intermediate top plate 2 with the fixed frame 100 and the intermediate frame 200. At this time, it is only necessary to keep the bolt holes of the fixed frame 100 and the intermediate frame 200 horizontal. There is no need to require high precision in the spacing of the bolt holes. The bottom plate 38 located at the bottom of the guide groove 33 is located on top of the strip hole A11 and the strip hole B22, and is used to cover the strip hole A11 and the strip hole B22 to ensure the overall aesthetics and sealing.

[0036] Reference Figure 1 , Figure 2 and Figure 3A reinforcing plate 12 is fixedly installed on the top of the fixed top plate 1, and the side of the fixed top plate 1 closest to the intermediate top plate 2 is inclined upwards. Transition plates 21 are rotatably installed on both sides of the intermediate top plate 2. The transition plates 21 are located on top of the fixed top plate 1 and are inclined downwards. A wear plate 23 is installed between the transition plate 21 and the fixed top plate 1, and the wear plate 23 is fixedly installed at the bottom of the transition plate 21. An end plate 14 is fixedly installed on the side of the fixed top plate 1 away from the intermediate top plate 2 by internal angle bolts 13. The end plate 14 is located between the passageway and the carriage.

[0037] After the fixed top plate 1 and the intermediate top plate 2 are installed, the side of the fixed top plate 1 closest to the intermediate top plate 2 is located at the bottom of the transition plate 21, serving as a support structure for the transition plate 21 to ensure the flatness and safety of the top of the passageway. To ensure the strength of the fixed top plate 1, a reinforcing plate 12 is installed on the top of the fixed top plate 1 for reinforcement. The strip hole B22, which is rotatably set on the outside of the intermediate top plate 2, slides in contact with the fixed top plate 1 through the wear plate 23 to ensure the normal use of the passageway's connection function.

[0038] In summary, the vehicle passageway roof mechanism disclosed in this application, when in use, adjusts the spacing of the other end of the support rods 31 by rotating the top of the fixed roof plate 1 and the intermediate roof plate 2, so that the spacing of the two support rods 31 is adapted to the bolt hole spacing of the fixed frame 100 and the intermediate frame 200. Then, the support rods 31 are connected to the outside of the fixed frame 100 and the intermediate frame 200 by the outer corner bolts 37 (note that the end of the support rod 31 is in a rotating state). Then, it enters the interior of the passageway, and the bolt heads 32 at the bottom of the fixed roof plate 1 and the intermediate roof plate 2 are rotated by using a wrench or other tools. The bolt head 32 drives the bidirectional lead screw 34 inside the guide groove 33 to rotate through the transmission box 36. The rotation of the bidirectional lead screw 34 synchronously adjusts the distance between the two sliders 35, causing the two sliders 35 to drive the ends of the support rods 31 to slide, thus changing the included angle between the two support rods 31. This allows for the adjustment of the distance between the fixed top plate 1 and the fixed frame 100, as well as between the intermediate top plate 2 and the intermediate frame 200. Finally, the fixed top plate 1 and the intermediate top plate 2 are connected to the side plates inside the passageway, facilitating the adjustment of the installation height of the top plate assembly of the passageway to adapt to different usage and installation conditions.
