Description

Technical Field

[0001] This invention relates to the field of rail vehicle equipment technology, and in particular to a through-passage structure and a rail vehicle. Background Technology

[0002] In rail vehicles, such as subways and light rails, adjacent carriages are connected by a passageway. This passageway provides a passage for passengers and offers functions such as sound insulation and dust protection. Currently, rail vehicles typically have two structural forms for passageways: those with inner protective panels and those without. Passageways with inner protective panels can isolate passengers from the passageway's folding canopy, thus protecting them. However, due to the structural limitations of the inner protective panel, this type of passageway can only be used for curves with larger radii. Generally, when the radius of the track is less than 150 meters, the internal structure of the inner protective panel occupies the internal space of the passageway, preventing vehicles from passing through. Passageways without inner protective panels only have a folding canopy structure. This structure is simple and can accommodate track lines with a minimum radius of 25 meters. However, passengers can directly contact the soft folding canopy within the passageway, posing a safety hazard of being pinched or injured.

[0003] Therefore, how to improve the turning performance and safety between adjacent vehicle bodies during turning is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a through-passage structure that connects adjacent vehicle bodies and has good turning performance and safety during vehicle turning.

[0005] Another object of the present invention is to provide a rail vehicle comprising the above-described through-passage structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A through-passage structure for connecting two adjacent vehicle body sections includes a frame and a bogie. The frame is a closed structure with a mounting bracket at the bottom, and an inner protective plate and an outer protective plate are respectively provided on the inner and outer sides of the frame. The bogie includes a main body and a rotating disk that are rotatably disposed relative to each other. The mounting bracket is fixed to the main body, and the rotating disk extends two rotating arms to connect the two ends of the vehicle body.

[0008] The inner and outer protective panels are respectively connected to the two sections of the vehicle body via flexible connecting parts on both sides. The vehicle body and the flexible connecting parts rotate relative to the main body when the vehicle turns, while the frame, the inner protective panel and the outer protective panel remain stationary relative to the main body when the vehicle turns.

[0009] Preferably, in the above-mentioned through-passage structure, a pedal is fixedly provided at the bottom of the frame, the vehicle body on both sides slides relative to the pedal, and a wear plate is provided on the contact surface between the pedal and the vehicle body.

[0010] Preferably, in the above-mentioned through-passage structure, the pedal is disc-shaped and partially embedded in the arc-shaped recessed area of ​​the vehicle body floor at both ends, and the center of the pedal is collinear with the center of the main body and the rotation center of the vehicle body at both ends in the vertical direction.

[0011] Preferably, in the above-described through-passage structure, in the vehicle length direction, the area of ​​the outer protective plate near both ends is inclined toward the interior of the vehicle body.

[0012] Preferably, in the above-mentioned through-passage structure, each outer protective panel is provided with an outer folding canopy on both sides in the vehicle length direction. One side of the outer folding canopy is connected to the outer wall of the vehicle body. The outer folding canopy covers the gap between the outer protective panel and the vehicle body and is stretched or contracted during vehicle operation.

[0013] Preferably, in the above-mentioned through-passage structure, a rubber baffle is provided on both sides of a single inner guard plate in the vehicle length direction. The single rubber baffle is bolted to the inner guard plate, and the other side overlaps with the inner wall of the vehicle body. The top and bottom of the rubber baffle are flush with the inner guard plate.

[0014] Preferably, in the above-mentioned through-passage structure, connecting folding canopies extend equidistantly from both sides of the frame, and the open edges of the connecting folding canopies are fixedly connected to the vehicle bodies on both sides.

[0015] Preferably, in the above-mentioned through-passage structure, the frame is provided with brackets on both sides facing the interior of the vehicle body and on both sides facing away from the exterior of the vehicle body, and the inner protective plate and the outer protective plate are connected to the brackets by bolts.

[0016] Preferably, in the above-mentioned through-channel structure, the frame is a rectangular structure and is made of aluminum alloy.

[0017] A rail vehicle includes at least two sections of the car body, and adjacent car bodies are connected by a through passage structure as described in any of the above embodiments.

[0018] As can be seen from the above technical solution, the through-passage structure provided by the present invention fixes the frame, inner protective plate, outer protective plate and bogie body into an integral structure, and connects the car body at both ends of the through-passage structure to the bogie's rotating disk, so that during vehicle operation and turning, the car body and rotating disk rotate relative to the main body, while the frame, inner protective plate and outer protective plate remain stationary relative to the main body, thus maintaining a stable passenger passage space and avoiding the risk of passengers being pinched due to the inner protective plate changing position during vehicle turning. At the same time, both sides of the inner and outer protective plates are connected to the car body on both sides through flexible connecting parts. The connection, through a flexible joint, seals the gaps between the inner and outer protective panels and the vehicle body, thus preventing the risk of passengers falling. At the same time, the deformation function of the flexible joint ensures that the inner and outer protective panels remain stationary relative to the main body during vehicle turning. During vehicle turning, one side of the inner protective panel, under the action of the flexible joint, intrudes into the space inside the vehicle body without obstructing the vehicle structure, thereby enabling the vehicle body to have a smaller turning radius. Meanwhile, the distance between the two inner protective panels remains unchanged, providing a stable passenger passage space and maintaining passenger safety under any vehicle operating conditions.

[0027] The core of this invention is to disclose a through-passage structure that can connect adjacent vehicle bodies and has good turning performance and safety during vehicle turning.

[0028] Another core aspect of this invention is to provide a rail vehicle that includes the aforementioned through-passage structure.

[0029] To enable those skilled in the art to better understand the present invention, embodiments of the present invention will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations shown in the embodiments below are not limited to those necessary for the solution of the invention described in the claims.

[0030] like Figure 1-6 As shown, the through-passage structure provided in this embodiment of the invention is used to connect two adjacent car body sections 80 in a rail vehicle. Specifically, the through-passage structure is a passageway structure with openings at both ends in the length direction of the car body 80. It mainly includes a frame 10 and a bogie 70. The frame 10 is a rigid support structure in the through-passage structure, and it is a closed structure in the circumferential direction of the car body 80 to have good rigidity. The bottom of the frame 10 is provided with a mounting bracket 20 for fixing the frame 10. In particular, in this invention... In the through passage structure provided in the embodiment, inner protective plates 30 are respectively provided on the two opposite inner walls of the frame 10 in the width direction of the vehicle body 80, while outer protective plates 40 are provided on the two outer walls of the frame 10. The inner protective plates 30 are used to protect passengers inside the through passage structure to provide passengers with a safe passage space, while the outer protective plates 40 can maintain a good vehicle shape and block the gap between the middle of the vehicle and the track when the vehicle is stopped, thereby preventing passengers from falling into the gap between the track and the middle of the vehicle and improving the safety performance during vehicle use.

[0031] The bogie 70 mainly includes a body 710 and a rotating disk. The rotating disk is rotatably mounted on the body 710. The mounting bracket 20 is fixedly connected to the body 710 so that the frame 10 and the body 710 remain relatively stationary during vehicle movement. The inner guard plate 30 and the outer guard plate 40 are preferably fixedly connected to the structure of the frame 10 by bolts so that the inner guard plate 30 and the outer guard plate 40 can be easily disassembled while maintaining a stable connection. At the same time, they also remain relatively stationary with the body 710 during vehicle operation. In addition, two rotating arms 720 are also provided extending from the rotating disk of the bogie 70 to connect with the car bodies 80 at both ends. The structure of the rotating disk and the rotating arms 720 allows the car bodies 80 at both ends to rotate synchronously with the rotating disk and also rotate relative to the body 710 during vehicle operation and turning.

[0032] Specifically, for the inner panel 30 located inside the passenger space, each inner panel 30 is connected to the two vehicle body sections 80 on both sides through flexible connecting parts. Since there are gaps between the inner panel 30 and the vehicle body 80, the flexible connecting parts are used to fill the corresponding gaps to protect the integrity of the passenger space. At the same time, the flexible connecting parts have a certain deformation capacity, so that the two ends of the vehicle body 80 can smoothly turn while maintaining the connection with the inner panel 30. Meanwhile, the flexible connecting parts can be squeezed or stretched to absorb the displacement generated during the vehicle movement, so that the vehicle movement has a certain flexible floating capacity and is more stable.

[0033] The outer protective plate 40 is similar to the above structure, and the vehicle body 80 can make turning smoothly through the deformation capability of the flexible connection.

[0034] In the above structure, the inner protective plate 30 and the outer protective plate 40 are fixedly connected to the frame 10 and the main body 710 as an integral structure. The inner protective plate 30 and the outer protective plate 40 are connected to the vehicle body 80 at both ends through flexible connecting parts. When the vehicle turns, the vehicle body 80 at both ends rotates relative to the main body 710. The inner protective plate 30 and the outer protective plate 40 remain relatively stationary with respect to the main body 710. At the same time, the vehicle body 80 achieves relative movement with the inner protective plate 30 and the outer protective plate 40 by means of the deformation of the flexible connecting parts. That is, during the straight-line movement and turning of the vehicle, the relative position of the inner protective plate 30 and the outer protective plate 40 inside the vehicle remains unchanged. Instead, the flexible connecting parts allow one side of the inner protective plate 30 to enter the vehicle interior without obstructing the turning of the vehicle, while the other side moves away from the vehicle interior. The distance between the two inner protective plates 30 does not change, so as to meet the needs of turning the vehicle while maintaining good passage space.

[0035] The through-passage structure provided in this embodiment of the invention fixes the frame 10, inner guard plate 30, outer guard plate 40, and bogie body 710 into a single structure. The vehicle body 80 at both ends of the through-passage structure is connected to the rotating disc of the bogie 70. This allows the vehicle body 80 and rotating disc to rotate relative to the body 710 during vehicle operation and turning, while the frame 10, inner guard plate 30, and outer guard plate 40 remain stationary relative to the body 710, maintaining a stable passenger passage space and avoiding the risk of passenger injury due to the inner guard plate 30 changing position during vehicle turning. Furthermore, both sides of the inner guard plate 30 and outer guard plate 40 are connected to the vehicle body 80 on both sides via flexible connecting parts, thus ensuring proper connection between the inner guard plate 30 and outer guard plate 40 and the vehicle body 80. The gaps between the body panels 80 are sealed to avoid the risk of passengers falling. At the same time, the deformation of the flexible connection ensures that the inner guard plate 30 and the outer guard plate 40 remain stationary relative to the body 710 during the turning process of the vehicle body 80. During the turning process of the vehicle body 80, the inner guard plate 30 on one side intrudes into the space inside the vehicle body 80 under the action of the flexible connection without obstructing the structure of the vehicle body 80. This allows the vehicle body 80 to have a smaller turning radius. In fact, there is no need to consider the interference problem of the inner guard plate 30 when turning. Therefore, the through passage structure provided by the embodiment of the present invention can meet the requirements of the vehicle turning 25 meters. At the same time, the distance between the inner guard plates 30 on both sides remains unchanged, providing a stable passenger passage space and maintaining the safety of passengers passing through in any operating state of the vehicle.

[0036] Furthermore, in order to facilitate the smooth passage of passengers within the passageway structure, in some embodiments of the present invention, a foot pedal 50 is fixedly installed at the bottom of the frame 10. Due to the fixed installation of the foot pedal 50 and the frame 10, it remains relatively stationary with the bogie body 710 during the straight-line movement and turning of the vehicle. In order to avoid the foot pedal 50 obstructing the turning process of the vehicle body 80, the two sides of the foot pedal 50 in the length direction of the vehicle body 80 need to be relatively slidably connected with the vehicle body 80 so that the vehicle body 80 rotates relative to the foot pedal 50 during the turning process, thus keeping the foot pedal 50 relatively stationary. This ensures that passengers will not experience any abnormalities when passing through the passageway structure during vehicle operation. It should also be noted that, in order to reduce the wear between the foot pedal 50 and the vehicle body 80, a wear plate is provided on the contact surface between the foot pedal 50 and the vehicle body 80 to protect the foot pedal 50 while reducing wear and noise caused by sliding.

[0037] Based on the above embodiments, the pedal 50 is preferably configured as a disc, which can be composed of multiple metal plates spliced ​​together to reduce production and assembly difficulty. Correspondingly, the two ends of the vehicle body 80 are respectively provided with arc-shaped recessed areas at the floor position. The radius of the recessed areas is the same as that of the disc, so that the two sides of the pedal 50 can be precisely embedded in the floor of the vehicle body 80. Furthermore, the center of the pedal 50, the center of the main body 710, and the rotation center of the two ends of the vehicle body 80 are collinear in the vertical direction. Based on this structure, when the vehicle is in a straight line, the center lines of the two ends of the vehicle body 80 intersect at the center of the circular pedal 50. When the vehicle is turning, the rotation center of the two ends of the vehicle body 80 is the center of the pedal 50, and the center lines of the two ends of the vehicle body 80 still intersect at the center of the circular pedal 50. The recessed area on the floor of the vehicle body 80 slides along the outer periphery of the pedal 50 to complete the rotation action, while the pedal 50 remains relatively stationary with respect to the main body 710.

[0038] The disc-shaped pedal 50 allows the rotation center of the vehicle body 80 to be located at the center of the pedal 50, so that the vehicle body 80 can rotate around the outer periphery of the pedal 50. During the rotation of the vehicle, the connection between the pedal 50 and the two ends of the vehicle body 80 will not change significantly, thus improving the passenger's vehicle body 80 experience. In addition, the pedal 50 uses less material, saving production costs.

[0039] To further optimize the above technical solution, in the through-passage structure provided in this embodiment of the invention, the outer protective plate 40 is a sheet material made of metal to maintain good rigidity on the outside of the vehicle body 80. At the same time, the two ends of the surface of the outer protective plate 40 are inclined inward, that is, in the length direction of the vehicle, the area of ​​the outer protective plate 40 near the two ends is inclined towards the inside of the vehicle body 80, so as to avoid the two sides of the vehicle body 80 interfering with the outer protective plate 40 due to the movement close to the outer protective plate 40 when the vehicle turns. The outer side of the outer protective plate 40 is parallel to the outer contour of the vehicle so as to cooperate with the vehicle body 80 and maintain a good vehicle appearance configuration when the vehicle moves.

[0040] Furthermore, in some embodiments of the present invention, the flexible connecting portion used to connect the outer protective plate 40 and the two sides of the vehicle body 80 is an outer folding canopy 410. Specifically, an outer folding canopy 410 is provided on both sides of a single outer protective plate 40 in the vehicle length direction, and the side of a single outer folding canopy 410 that is not connected to the outer protective plate 40 is connected to the outer wall of the vehicle body 80. The outer folding canopy 410 is a deformable connecting structure with folds. When the vehicle turns, the outer folding canopy 410 is stretched and compressed according to the vehicle state, while constantly blocking and protecting the gap between the outer protective plate 40 and the vehicle body 80. It should be noted that when the vehicle is in the minimum turning state, the stretched state of the outer folding canopy 410 on the stretched side is less than its ultimate stretched state. At the same time, the compressed state of the outer folding canopy 410 on the compressed side is less than its ultimate compressed state, so as to maintain the good structural effect of the outer folding canopy 410 in the full running state of the vehicle.

[0041] Furthermore, in some embodiments of the present invention, the flexible connecting part for connecting the inner guard plate 30 and the two sides of the vehicle body 80 is a rubber baffle 310. Specifically, a rubber baffle 310 is provided on both sides of a single inner guard plate 30 in the length direction of the vehicle. The rubber baffle 310 is fastened to the inner guard plate 30 by bolts, and the other end is overlapped and fixed to the inner wall of the vehicle body 80. It should also be noted that the top and bottom of the rubber baffle 310 are flush with the top and bottom of the inner guard plate 30, so that the rubber baffle 310 can completely cover the gap between the inner guard plate 30 and the vehicle body 80, thereby protecting the safety of passengers passing through. At the same time, the flexible structure of the rubber baffle 310 allows it to deform when squeezed by the vehicle body 80 during vehicle movement, thereby absorbing the displacement generated during vehicle movement. As a structural component that passengers can directly contact, the rubber baffle 310 has a better tactile feel.

[0042] In the through passage structure provided in this embodiment of the invention, the frame 10 is a rigid structural component. In order to enable the through passage structure to provide passengers with a closed passage area, connecting folding canopies 60 extend equidistantly from both sides of the frame 10. The open edges of the connecting folding canopies 60 in the length direction of the vehicle body 80 are fixedly connected to the vehicle bodies 80 on both sides. The connecting folding canopies 60 are cylindrical structures to form a closed inner ring, which isolates the passenger compartment from the outside, provides a comfortable interior space, and can absorb the deformation generated during vehicle movement, so that the through passage structure maintains a good connection effect with the vehicle bodies 80 on both sides.

[0043] Furthermore, it should be noted that since the inner protective plate 30 and the outer protective plate 40 are structural accessories, they require maintenance and replacement. Therefore, it is preferable that the frame 10 is provided with brackets on both inner walls facing the inside of the vehicle body 80 and on both sides facing away from the outside of the vehicle body 80. The inner protective plate 30 and the outer protective plate 40 are connected to the brackets by bolts to facilitate the assembly and disassembly of the inner protective plate 30 and the outer protective plate 40.

[0044] Furthermore, in order to maintain the rigidity of the through-passage structure and meet the lightweight requirements of the vehicle, in some embodiments of the present invention, the frame 10 is a rectangular structure and is made of aluminum alloy.

[0045] In another embodiment of the present invention, a rail vehicle is also provided, which includes at least two spaced-apart car bodies 80. Adjacent car bodies 80 are connected into an integral structure by a through passage structure provided in any of the above embodiments. Since the through passage structure has the above-mentioned technical effects, the rail vehicle also has the above-mentioned technical effects, which will not be repeated here.
