Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and more specifically, to a rail vehicle, a car body, and a side door mechanism suitable for concealed doors. Background Technology

[0002] To facilitate passenger boarding and alighting, rail vehicles are often equipped with side doors on their side walls. These side doors commonly come in two structural forms: sliding doors and concealed doors. To accommodate the installation requirements of different door structures, the car body often needs to be adapted to the door structure. For the widely used concealed doors, to ensure sufficient movement space after the concealed door is installed on the rail vehicle, the car body often incorporates internal pillars within the reserved side door installation space. However, in actual production and maintenance practice, the applicant found that concealed doors are not easy to install onto the car body, and disassembling them during maintenance requires the removal of a large area of ​​the interior, making maintenance operations cumbersome.

[0003] In conclusion, how to reduce the difficulty of installing and maintaining concealed doors is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0040] 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.

[0041] The core of this utility model is to provide a side door mechanism suitable for concealed doors, which greatly reduces the difficulty of installing and maintaining concealed doors. Another core aspect of this utility model is to provide a vehicle body including the aforementioned side door mechanism for concealed doors. Yet another core aspect of this utility model is to provide a rail vehicle including the aforementioned vehicle body.

[0042] This utility model provides a side door mechanism suitable for concealed doors, including a sill 1 and an interior pillar 2. The interior pillar 2 includes an upper pillar structure 21 and a lower pillar structure 22. The lower pillar structure 22 is fixed to the sill 1, and the upper pillar structure 21 is detachably installed on the lower pillar structure 22 and the vehicle side wall 13. The lower pillar structure 22 is located at the bottom of the upper pillar structure 21. The upper pillar structure 21 and the lower pillar structure 22 are arranged opposite to each other on the vehicle side wall 13, and there is an installation space 3 and an activity space 4 between them. The activity space 4 is used for the opening and closing movement of the concealed door body, and the installation space 3 is used to accommodate the drive mechanism of the concealed door.

[0043] refer to Figure 1 As explained, the interior pillar 2 is divided into two parts: an upper pillar structure 21 and a lower pillar structure 22. The lower pillar structure 22 is located below the upper pillar structure 21. The bottom end of the lower pillar structure 22 is fixed to the sill 1 by welding or riveting. The upper pillar structure 21 is detachably connected to the lower pillar structure 22 and the vehicle side wall 13 by threaded connection or snap-fit ​​connection to achieve installation. The upper pillar structure 21 and the lower pillar structure 22 are set opposite to the vehicle side wall 13, and a space is left between them as an installation space 3 and an activity space 4. The installation space 3 and the activity space 4 are two parts of the space between the interior pillar 2 and the vehicle side wall 13. The installation space 3 is located above the activity space 4, and the drive mechanism located inside the installation space 3 can drive the interior door body to move horizontally.

[0044] refer to Figure 1 and Figure 2 As explained, the upper column structure 21 has a protruding mounting portion, and the protruding mounting portion preferably adopts... Figure 1 and Figure 2 The trapezoidal protrusion shown can also be arched or rectangular. The protrusion mounting part protrudes towards the inside of the vehicle, so that the distance between the protrusion mounting part and the side wall 13 of the vehicle body is greater than the distance between the lower structure of the upper pillar structure 21 and the side wall 13 of the vehicle body, so as to accommodate the drive mechanism of the inner door. When the inner door needs to be installed or repaired, the upper pillar structure 21 is removed to avoid the upper door interior pillar 2 blocking the translation of the inner door. Then, the body of the inner door and the drive mechanism are placed in the target position to complete the installation. Then, the upper pillar structure 21 is reinstalled. Compared with related technologies, the installation and repair of the inner door are much easier when using this side door mechanism, which greatly improves efficiency and reduces the amount of interior disassembly work during the repair process. In addition, since the interior pillar 2 does not have a connection relationship with the vehicle body and roof, it is easier to control the tolerance during process design, which is beneficial to improving installability.

[0045] Based on the above embodiment, it also includes several mounting pads 5. The mounting pads 5 are clamped at the corresponding connection positions between the upper column structure 21 and the vehicle side wall 13. At least two mounting pads 5 have different thicknesses, and the sum of the thicknesses of all mounting pads 5 with different thicknesses is equal to 6mm.

[0046] The side door mechanism is equipped with at least two different thicknesses of mounting shims 5. Preferably, the thickness of several mounting shims 5 is 1mm, 2mm or 3mm. Any one mounting shim 5, any two mounting shims 5, or three or more mounting shims 5 with a total thickness of less than or equal to 6mm can be selected. With such a setting, the adjustment can be made with a minimum adjustment tolerance of 1mm. Of course, the thickness of several mounting shims 5 is not limited to the above examples, as long as the position adjustment can be achieved by selecting and using mounting shims 5.

[0047] Please refer to the following when using it. Figure 4 Alternatively, an installation pad can be used to clamp the corresponding connection position between the vehicle body side wall 13 and the upper column structure 21, allowing connecting rods such as bolts 11 to pass through, thereby adjusting the distance between the upper column structure 21 and the vehicle body side wall 13, ensuring that the space between the vehicle interior column 2 and the vehicle body side wall 13 meets the requirements for door movement.

[0048] Based on the above embodiments, the mounting gasket 5 adopts a C-type gasket, that is, an open gasket, so when the mounting gasket 5 needs to be replaced, the entire structure does not need to be disassembled, and online replacement can be achieved.

[0049] refer to Figure 1 As can be seen, based on the above embodiments, the lower column structure 22 is provided with fixed interfaces 221 for connecting the interior cover panel and / or for connecting the decorative panel and / or for running pipes and / or for running cables. This can reduce the space required for wiring and / or pipe laying inside the vehicle and facilitate the installation of the interior cover panel and / or decorative panel. It should be noted that the number, arrangement and type of fixed interfaces 221 are not limited, as long as they meet the connection requirements of the target components such as the interior cover panel and / or decorative panel and / or pipes and / or cables.

[0050] refer to Figure 1 As can be seen, based on the above embodiment, the lower column structure 22 adopts a hollow profile, and the internal cavity of the lower column structure 22 is filled with heat insulation filler 222 to play the role of noise reduction, heat insulation and vibration reduction. The heat insulation filler 222 can be glass wool or foam, etc.

[0051] Based on the above embodiment, a door frame 6 is also included, and the threshold 1 is welded flush with the door frame 6.

[0052] refer to Figure 5As explained, the top plate of the door frame 6 has a stepped surface on the side closest to the vehicle interior. The door sill 1 overlaps with the stepped surface of the door frame 6 and is welded flat to the door frame 6 to form a whole, which ensures both connection strength and sealing, as well as unobstructed drainage in the area of ​​the door sill 1.

[0053] Based on the above embodiments, both the upper pillar structure 21 and the lower pillar structure 22 are hollow profiles, and water baffles 7 are provided at the side wall openings of the interior pillar 2 near the activity space 4 and at the gap between the pillar 2 and the door frame 6 to close the openings.

[0054] refer to Figure 7 As explained, both the upper pillar structure 21 and the lower pillar structure 22 are made of hollow profiles. Based on this, to prevent external liquids from entering the vehicle interior, a water-blocking plate 7 is installed at the openings in the side panels of the interior pillar 2 near or in contact with the activity space 4. Simultaneously, a water-blocking plate 7 is installed in the gap between the interior pillar 2 and the door frame 6. Through welding or adhesive bonding, the water-blocking plate 7 is sealed to the main structure to isolate the water-contaminated area from the interior space of the passenger compartment, ensuring water tightness and preventing rainwater from spreading into the passenger compartment, thus ensuring the safety of the internal structure.

[0055] Based on the above embodiment, it also includes a drainage trough 8 and a drainage pipe 9; the drainage trough 8 is located at the bottom of the activity space 4 and is used to receive liquid falling from the inner door, and the height of the first end of the drainage trough 8 is lower than the height of its second end; the top end of the drainage pipe 9 is connected to the first end of the drainage trough 8 and is used to receive liquid in the drainage trough 8 and guide its flow.

[0056] refer to Figure 1 , Figure 6 As explained, a straight, horizontally extending, and open-topped drainage trough 8 is provided on the outer side of the interior pillar 2 and the inner side of the door frame 6. That is, the drainage trough 8 is located at the bottom of the activity space 4 so that it can receive liquid dripping from the interior door body after the interior door body moves into the interior of the vehicle. A drainage pipe 9 is connected to the bottom of the drainage trough 8. The drainage pipe 9 is preferably a straight pipe. The top end of the drainage pipe 9 is connected to the right end of the drainage trough 8 away from the sill 1. It is used to receive the liquid in the drainage trough 8 and guide it to flow out. That is, rainwater and other liquids on the interior door can be smoothly discharged to the bottom of the vehicle through the drainage pipe 9 to prevent water accumulation inside the vehicle body. Preferably, the height of the first end of the drainage trough 8 away from the sill 1 is lower than the height of its second end near the sill 1 to avoid water accumulation in the drainage trough 8.

[0057] Furthermore, it also includes a cover plate 10, which is rotatably connected to the bottom end of the drain pipe 9, and the cover plate 10 is magnetically connected to or detached from the drain pipe 9 to close or open the bottom opening of the drain pipe 9. Specifically, as shown in... Figure 9As shown, a rotatable cover plate 10 is connected to the bottom end of the drain pipe 9. The cover plate 10 can be a round plate or a square plate, as long as it can close the bottom opening of the drain pipe 9. The cover plate 10 is magnetically attracted to the drain pipe 9. That is, the drain pipe 9 and / or the cover plate 10 are equipped with magnets, or the whole is made of magnets, so as to realize the magnetic attraction function. When the weight of the liquid in the drain pipe 9 is greater than the magnetic attraction force, the cover plate 10 will open automatically, so as to realize drainage. When no water is discharged, it will automatically close again, which plays a role in preventing backflow and dust, and preventing foreign objects from entering the vehicle body through the drain pipe 9.

[0058] In some embodiments, the upper column structure 21 and the lower column structure 22, and the upper column structure 21 and the vehicle side wall 13 are fixedly connected by at least two bolts 11; and / or, the lower column structure 22 is welded to the sill 1.

[0059] Preferred, Reference Figure 2 , Figure 4 , Figure 8 In short, the upper pillar structure 21 and the lower pillar structure 22, as well as the upper pillar structure 21 and the vehicle side wall 13, are all connected by bolts 11, allowing for easy assembly and disassembly of the upper pillar structure 21. Meanwhile, the lower pillar structure 22 is welded to the sill 1. Figure 3 As shown, this design ensures a high-strength connection between the lower column structure 22 and the threshold 1 while maintaining a tight seal.

[0060] Furthermore, at the connection point between the upper column structure 21 and the lower column structure 22, a rivet nut 12 is fixed on the inner side of the lower column structure 22. Therefore, when assembling the upper column structure 21 and the lower column structure 22, the bolt 11 can be tightened directly, without the need to manually assemble the bolt 11 and nut 12, which improves the operability of the structure when installing in a confined space.

[0061] Based on the above embodiment, the upper column structure 21 has a mounting through hole 211, through which the bolt 11 can be moved vertically.

[0062] refer to Figure 8 As explained, the top of the upper column structure 21 has a vertically extending elongated hole as a mounting through hole 211, which enables the upper column structure 21 to be adjusted vertically. The matching bolt 11 can be a T-bolt 11. The above-mentioned vertical adjustment function helps to reduce the difficulty of disassembling and assembling the upper column structure 21. For example, the upper column structure 21 can be installed on the side wall 13 of the vehicle body first, and then the upper column structure 21 can be connected to the lower column structure 22. During the connection process, if necessary, the height position of the upper column structure 21 can be adjusted.

[0063] Based on the above embodiment, there are two interior pillars 2, namely, two upper pillar structures 21 and two lower pillar structures 22. One upper pillar structure 21 and one corresponding lower pillar structure 22 are grouped together to form one interior pillar 2, and another upper pillar structure 21 and another corresponding lower pillar structure 22 are grouped together to form another interior pillar 2. In one interior pillar 2, the upper pillar structure 21 is located above and connected to the lower pillar structure 22, and the two interior pillars 2 are respectively used to be installed on both sides of the door mounting space.

[0064] Furthermore, there are also two drainage channels 8 and two drainage pipes 9. One drainage channel 8 and a corresponding drainage pipe 9 are set together, and the other drainage channel 8 and the other corresponding drainage pipe 9 are set together. In the drainage channel 8 and drainage pipe 9 set together, the drainage channel 8 is located directly above the drainage pipe 9 and connected to it. In addition, the two sets of drainage channels 8 and drainage pipes 9 are respectively used to set on both sides of the door installation space. The set of drainage channels 8 and drainage pipes 9 are located at the bottom of the movable space between the interior pillar 2 and the side wall 13 of the vehicle body, which are on the same side of the door installation space as themselves.

[0065] like Figure 1 and Figure 2 As shown, based on the above embodiment, the upper column structure 21 has a protruding mounting part, a top foot, and a bottom foot. The bottom foot is connected to the top edge of the protruding mounting part and is used to abut against the inner side of the vehicle body side wall 13. The bottom foot is connected to the bottom edge of the protruding mounting part and is used to abut against the inner side of the lower column structure 22. Furthermore, both the top foot and the bottom foot have several mounting through holes for the connecting rod to pass through, so as to fix the two abutting parts together.

[0066] Furthermore, it also includes a sealing gasket, which is used to clamp between the base of the upper column structure 21 and the inner side of the lower column structure 22 to ensure the sealing of the connection between the upper column structure 21 and the lower column structure 22, thereby preventing water mist from penetrating into the interior of the passenger compartment and ensuring the safety of the internal structure.

[0067] Based on the above embodiment, the second end of the drainage channel 8 near the threshold 1 has a sealing plate, the first end of the drainage channel 8 away from the threshold 1 is open, and the first end of the drainage channel 8 away from the threshold 1 overlaps with the threshold 1 to receive accumulated liquid on the threshold 1. (Refer to...) Figure 1 and Figure 6 As explained, the left end of the drainage channel 8 overlaps the sill 1, and the left end of the drainage channel 8 is open, so the liquid flowing down the sill 1 can enter the drainage channel 8. The closed right end of the drainage channel 8 is lower than its open left end, so the liquid will be guided to the right end by the drainage channel 8 and discharged to the bottom of the vehicle through the drainage pipe 9.

[0068] Based on the above embodiments, the bottom of the upper column structure 21 and the top of the lower column structure 22 are both reinforced with ribs, and the reinforcing ribs of the upper column structure 21 abut against the reinforcing ribs of the lower column structure 22, and the two fit together to improve the overall strength and rigidity of the structure, which helps to reduce the possibility of loosening, deformation or even breakage at the connection between the upper column structure 21 and the lower column structure 22.

[0069] It should be noted that the type of reinforcing rib is not limited, as long as it meets the requirements for improving structural strength and stiffness. For example, in some embodiments, the reinforcing ribs of the upper column structure 21 and the lower column structure 22 can both be annular reinforcing ribs. The reinforcing ribs of the upper column structure 21 are arranged around its bottom connecting surface, and similarly, the reinforcing ribs of the lower column structure 22 are arranged around its top connecting surface to provide uniform support. Alternatively, in some embodiments, the reinforcing ribs of the upper column structure 21 and the lower column structure 22 can both be triangular reinforcing ribs. Several reinforcing ribs of the upper column structure 21 are arranged around its bottom connecting surface, and similarly, several reinforcing ribs of the lower column structure 22 are arranged around its bottom connecting surface. Several reinforcing ribs of the upper column structure 21 abut against the corresponding reinforcing ribs of the lower column structure 22.

[0070] Based on the above embodiments, a fault monitoring component is also included. The fault monitoring component includes a connection status monitor, a sealing status monitor, and a controller. Specifically, a connection status monitor is provided at the connection between the upper column structure 21 and the lower column structure 22 to monitor whether the upper column structure 21 and the lower column structure 22 are securely connected. A sealing status monitor is provided at the connection between the upper column structure 21 and the lower column structure 22 to monitor whether the upper column structure 21 and the lower column structure 22 are sealed. Both the connection status monitor and the sealing status monitor are signal-connected to the controller and are used to issue an alarm when the connection between the upper column structure 21 and the lower column structure 22 becomes loose or when leakage occurs at the connection. This allows for timely detection of abnormalities in the connection status and sealing condition between the upper column structure 21 and the lower column structure 22, preventing further deterioration after problems occur at the connection between the upper column structure 21 and the lower column structure 22, facilitating timely maintenance, and ensuring safety.

[0071] It should be noted that there are no restrictions on the type of connection status monitor, as long as it can monitor whether the upper column structure 21 and the lower column structure 22 are kept securely connected. For example, a pressure sensor or displacement sensor can be used between the upper column structure 21 and the lower column structure 22 to detect the pressure and relative displacement between them, thereby reflecting whether the connection between the upper column structure 21 and the lower column structure 22 is secure or loose.

[0072] It should also be noted that there are no restrictions on the type of sealing status monitor, as long as it can monitor whether the upper column structure 21 and the lower column structure 22 are kept sealed. For example, a fiber optic sensor embedded in the sealing gasket between the upper column structure 21 and the lower column structure 22 can be used to detect the pressure on the sealing gasket. Alternatively, a humidity sensor placed near the connection between the upper column structure 21 and the lower column structure 22 can be used to reflect whether the sealing between the upper column structure 21 and the lower column structure 22 is sealed or leaking.

[0073] In addition to the side door mechanism applicable to concealed doors described above, this utility model also provides a vehicle body that includes the side door mechanism applicable to concealed doors disclosed in the above embodiments. For the structure of other parts of the vehicle body, please refer to the prior art, which will not be repeated here.

[0074] It should be noted that there is no limitation on the number of side door mechanisms for the concealed doors included in the vehicle body. For example, in some embodiments, four door installation spaces are reserved on one side wall of the vehicle body and four door installation spaces are also reserved on the other side wall, that is, when eight concealed doors need to be set, then in this embodiment, the vehicle body may include eight side door mechanisms for the concealed doors.

[0075] In addition to the side door mechanism applicable to concealed doors described above, this utility model also provides a rail vehicle including the car body disclosed in the above embodiments. The rail vehicle also includes at least two concealed doors, and the structure of other parts of the rail vehicle is described in the prior art, which will not be repeated here.

[0076] In some embodiments, the number of concealed doors is equal to the number of side door mechanisms applicable to the concealed doors included in the vehicle body, so as to ensure that the installation difficulty of each concealed door of the rail vehicle is low.

[0077] It should be noted that the relational terms such as "first" and "second" mentioned above are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities; the terms "upper surface," "lower surface," "top," and "bottom" and the directional terms "upper," "lower," "left," and "right" mentioned above are defined based on the accompanying drawings in the specification.
