Conventional structures or constructions will be omitted where they may cause confusion in understanding this disclosure.

[0043] It should be noted that the following driver's cab will be in the form of Figure 2 The structure shown is illustrated below. The driver's cab has a length direction (X-direction), a width direction (Y-direction), and a height direction (Z-direction). Here, the length direction can also be understood as the length of the rail vehicle, the height direction as the height of the rail vehicle, and the width direction as the width of the rail vehicle. Unless otherwise specified, the length, width, and height directions of the driver's cab can be referred to... Figure 2 As shown.

[0044] Figure 1 A schematic side view of the driver's cab according to an embodiment of the present disclosure is shown. Figure 2 An exploded view of the driver's cab according to an embodiment of the present disclosure is shown schematically. Figure 2 No escape doors were shown.

[0045] As one aspect of this disclosure, a driver's cab is provided, such as... Figure 1 and Figure 2 As shown, the driver's cab includes a supporting beam 1, a cover 2, an escape door, and an upper cover 4. The supporting beam 1 is connected to the vehicle body structure (not shown in the figure). The cover 2 is installed over the supporting beam 1 and extends along the length of the vehicle. Figure 2An opening is formed at one end (e.g., at the front end in the direction of travel of the rail vehicle) in the X direction shown. An escape door is disposed at the opening, and the escape door includes a door body 3 and a drive mechanism at least partially disposed above the door body 3. The drive mechanism is located inside the driver's cab, therefore... Figure 1 (Not shown) is configured to drive the door 3 to open and close. An upper cover 4 is disposed between the upper edge of the opening and the door 3 and is connected to the cover 2 to cover the drive mechanism.

[0046] In such an embodiment, an opening that matches or is slightly larger than the overall structure of the escape door can be provided. The escape door is installed on the supporting beam 1 and the cover 2. The drive mechanism protruding from the door body 3 is covered by the upper cover plate 4. In this way, the internal structure of the escape door is protected, and the integrity and aesthetics of the driver's compartment are maintained.

[0047] According to embodiments of this disclosure, rail vehicles may include urban rail transit such as subways and light rail.

[0048] According to embodiments of this disclosure, the drive mechanism may include a hydraulic cylinder, a pneumatic cylinder, or a drive motor, etc. It is understood that the escape door may also include other internal mechanisms such as a locking mechanism, and these internal mechanisms, at least partially located above or below the door body 3, may all be covered by the upper cover plate 4.

[0049] As an example, such as Figure 1 As shown, the projected area of ​​the escape door along its length can exceed one-quarter of the projected area of ​​the driver's cab. The overall structure of the escape door is larger than that of the driver's cab, allowing passengers to evacuate more quickly and orderly, avoiding congestion at the exit and gaining a crucial advantage in escaping precious time.

[0050] Figure 3 A perspective view of a cover according to an embodiment of the present disclosure is shown schematically.

[0051] According to embodiments of this disclosure, such as Figures 1 to 3 As shown, the cover 2 also has a front window interface 24, a side window interface 25, a windshield wiper interface 26, a headlight interface 27, and a skirt panel interface 28, which are arranged on both sides of the opening along the width direction.

[0052] According to embodiments of this disclosure, the cover 2 may be made of composite material.

[0053] As an example, the front window interface 24, side window interface 25, windshield wiper interface 26, headlight interface 27, and skirt panel interface 28 can be integrally formed with the cover.

[0054] According to embodiments of this disclosure, the cover 2 can be a curved structure. The cover 2 can be provided with through holes and magnets for mounting the wiper shaft, for mounting the main wiper structure.

[0055] The windshield wiper interface consists of a fiberglass cover, a magnet, and a wiper shaft connector. The fiberglass cover serves an aesthetic and decorative purpose. The wiper shaft connector and magnet are used for the passage and magnetic attachment of the wiper shaft to the stainless steel wiper panel.

[0056] Figure 4 A partial perspective view of the driver's cab door in a closed state, according to an embodiment of the present disclosure, is shown schematically. Figure 5 It shows Figure 4 The diagram shows a partial perspective view of the driver's cab with the door open.

[0057] According to embodiments of this disclosure, such as Figures 1 to 5 As shown, the gate 3 is configured relative to the cover 2 in a direction parallel to the width of the rail vehicle (e.g., Figure 2 Rotation along the axis shown in the Y direction, and located above door 3. For example, door 3 rotates from... Figure 4 Rotate to the position shown Figure 5 The location shown.

[0058] As an example, the maximum rotation angle of door 3 can be a right angle or an obtuse angle.

[0059] Figure 6 A perspective view of the upper cover plate according to an embodiment of the present disclosure is shown schematically.

[0060] According to embodiments of this disclosure, such as Figures 4 to 6 As shown, the upper cover 4 includes a body 41 and an extension 43. The body 41 is connected to the cover 2, and the extension 43 extends downward and inward from the lower edge of the body 41 to avoid the door 3 when the door 3 is open.

[0061] According to the embodiments of this disclosure, when the door 3 flips upward, the upper edge of the door 3 is likely to collide with the fixed upper cover plate 4, resulting in the door being unable to open or the upper cover plate 4 being damaged. The downward and inwardly inclined extension 43 creates a safe avoidance zone for the movement trajectory of the door 3, enabling the door 3 to safely achieve a rotation angle of 90° or even greater, ensuring the overall structural integrity of the door 3 and the upper cover plate 4.

[0062] The upper cover 4 can be made of a lightweight composite material structure. The upper cover 4 is located at the front of the enclosure 2, above the escape door. It provides support and a sealing interface for the escape door, employing a secondary waterproof structure to improve sealing and installation.

[0063] like Figure 6 As shown, the upper cover 4 also includes a headlamp interface 45, which is used to mount a headlamp.

[0064] According to an embodiment of this disclosure, the extension 43 is in the shape of a downwardly sloping arc, forming a guiding slope, which can effectively guide rainwater to flow down the extension 43 and prevent rainwater from accumulating or flowing back into the driver's cab.

[0065] According to embodiments of this disclosure, the driver's cab may further include a rain gutter (not shown in the figure). The rear of the rain gutter is connected to the front of the vehicle body by overlapping and applying sealant. The rain gutter is connected to studs pre-embedded in the cover 2. The rain gutter has a large through hole to adjust the relative position of the rain gutter and the cover 2 by bolts, making installation and disassembly convenient and the connection firm. At the same time, sealant is applied at the connection between the rain gutter and the cover 2 to further enhance waterproofing.

[0066] According to embodiments of this disclosure, such as Figures 3 to 6 As shown, the upper edge of the body 41 is recessed inward to form a flange 411. A joint 22 is formed at the position of the cover 2 facing the flange, and the flange 411 abuts against the joint 22 to connect the upper cover plate 4 to the cover 2.

[0067] As an example, such as Figures 4 to 6 As shown, multiple through holes can be formed on the flange 411, and multiple mating holes are formed on the joint 22 facing the configuration of the multiple through holes. Multiple bolts pass through the multiple through holes and mating holes respectively, and are connected to the cover 2 by engaging with nuts. It can be understood that a sealing strip can also be provided between the flange 411 and the joint 22 to further improve the sealing performance of the connection between the flange 411 and the joint 22.

[0068] The flange 411 formed by the inward indentation of the upper edge of the body 41 can accommodate the bolt head (or nut end) in the space formed by the indentation of the upper cover plate 4 after the bolt passes through the mating hole of multiple through holes, thus preventing the bolt head from protruding outside the cover 2. In this way, there are no protruding metal parts visible from the outside of the cover 2, avoiding the visual clutter and abruptness caused by the bolt head, and improving the cleanliness and aesthetics of the driver's cab.

[0069] Alternatively, the flange 411 and the joint 22 can be connected by means of bonding or riveting.

[0070] In this embodiment, the flange 411 formed by the indentation of the upper edge of the body 41 plays a guiding and positioning role during assembly, ensuring that the upper cover plate 4 can be inserted into the cover 2 in the only correct posture, eliminating the possibility of misassembly or misalignment. When the flange 411 fully abuts against the joint 22, the relative position between the flange 411 and the joint 22 is constrained by multiple bolts, rivets, adhesives, etc., forming a stable mechanical connection structure.

[0071] According to an embodiment of this disclosure, the escape door further includes a support frame, to which a drive mechanism is connected. A plurality of connecting posts extend from the inner side of the body 41 in a direction opposite to the outer surface of the body 41, for connection to the support frame via the plurality of connecting posts.

[0072] The support frame can be a roughly frame-shaped structure, installed on the support beam 1. The support frame door can be connected to the support frame via an internal mechanism. The connecting column extends from the inside of the main body 41 towards the support frame, which is equivalent to adding multiple local reinforcing ribs to the main body 41.

[0073] As an example, multiple connecting brackets can be connected to a metal bracket set on a support frame.

[0074] As an example, the number of connectors can be 3, 4, or 5. This can be configured as needed.

[0075] Figure 7 A first-view perspective view of the lower cover plate according to an embodiment of the present disclosure is schematically shown. Figure 8 A second perspective view of the lower cover plate according to an embodiment of the present disclosure is schematically shown.

[0076] According to embodiments of this disclosure, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the driver's cab also includes a lower cover plate 5, which is disposed at the opening and connected to the cover body 2 at the bottom of the escape door to cover the bottom of the escape door.

[0077] The lower cover 5 can be installed after the escape door, which further facilitates the installation of the escape door. By sealing the gap between the bottom of the escape door and the cover 2, the lower cover 5 provides basic environmental protection, effectively blocking the intrusion of dust, rainwater, etc., thereby protecting the delicate electrical equipment inside the driver's cab and improving sound insulation and heat preservation performance. By setting the lower cover 5, the originally irregular gaps can be smoothed, guiding airflow smoothly, reducing wind noise caused by airflow disturbance, optimizing aerodynamic performance during high-speed operation, and creating a safe, reliable, quiet and comfortable working environment.

[0078] According to an embodiment of this disclosure, the door 3 is mounted on the support beam 1 via a support frame. The lower cover plate 5 is connected to the bottom of the support frame and covers the bottom of the support frame.

[0079] According to an embodiment of this disclosure, the lower cover 5 is located at the front of the cover 2 of the driver's cab, below the escape door, providing support and a sealing interface for the escape door.

[0080] According to embodiments of this disclosure, such as Figure 7 and Figure 8As shown, the lower cover 5 includes a base plate 52, a side plate 53, and a mounting bracket 54. The side plate 53 extends from the base plate 52 along the height direction, and the lower edge of the side plate 53 is connected to the underframe buffer beam of the vehicle body structure. The mounting bracket 54 is disposed on the base plate 52 or the side plate 53 and is suitable for connection with the support frame of the escape door.

[0081] According to an embodiment of this disclosure, the frame buffer beam is installed below the support beam column 1.

[0082] According to embodiments of this disclosure, the base plate 52 and the side plate 53 constitute a generally T-shaped support structure. The lower edge of the side plate 53 is directly connected to the underframe buffer beam of the car body structure. The lower cover plate 5 can partially transfer and disperse the weight of the escape door and drive mechanism and the impact force during operation to the underframe of the car body, ensuring the stability of the entire escape door under high-speed operation and vibration of the train.

[0083] As an example, the lower edge of the side plate 53 protrudes from the base plate 52 and can be connected to the mounting seat on the base frame buffer beam by means of bonding, screwing, riveting, etc.

[0084] Figure 9 A partial cross-sectional perspective view of the driver's cab according to an embodiment of the present disclosure is shown schematically.

[0085] According to embodiments of this disclosure, such as Figures 1 to 9 As shown, the upper cover plate 4 also includes a connecting portion 42 extending downward from the lower edge of the extension portion 43. The lower edge of the connecting portion 42 bends outward in a direction away from the supporting beam column 1 to form an upper bend portion 44. The two side walls of the cover body 2 facing each other along the width direction of the rail vehicle bend outward in a direction away from the supporting beam column 1 to form side bend portions 21. The upper edge of the lower cover plate 5 bends outward in a direction away from the supporting beam column to form a lower bend portion 51. Further, the lower bend portion 51 protrudes outward from the upper edge of the side plate 53. The upper bend portion 44, the two side bend portions 21, and the lower bend portion 51 form a waterproof edge, which is suitable for abutting against the door body when the door body is in the closed state.

[0086] According to an embodiment of this disclosure, rainwater or cleaning water flows downward along the extension 43. When the rainwater or cleaning water flows to the door seam area, it first encounters this outwardly extending waterproof edge. Due to gravity and surface tension, the water flow is guided downward along the outer surface of the waterproof edge and eventually discharged from the bottom, preventing rainwater or cleaning water from seeping into the driver's cab.

[0087] According to embodiments of this disclosure, such as Figure 9 As shown, the driver's cab also includes a sealing strip 31. The sealing strip 31 is disposed between the waterproof edge and the door body 3 to seal the waterproof edge and the door body 3.

[0088] In this embodiment, the sealing strip 31 is disposed between the waterproof edge and the door body 3, filling the tiny gap between the waterproof edge and the door body 3, forming a seamless physical barrier, reducing the penetration of water, air, and sound. Furthermore, the sealing strip 3 can absorb the impact force when the door body 3 closes and the vibration during train operation, playing a buffering and protective role, reducing wear between the rigid door body 3 and the waterproof edge, further reducing noise, and creating a dry, quiet, and comfortable internal environment for the driver's cab.

[0089] As an example, the sealing strip 31 can be attached to the inside of the door body 3.

[0090] According to the embodiments of this disclosure, the cover 2, the upper cover plate 4, and the lower cover plate 5 together constitute the sealing and support structure of the door panel 3 of the escape door, and the lower bend 51 protrudes outward from the upper edge of the side plate 53. The upper bend 44, the two side bends 21, and the lower bend 51 form a waterproof edge, which can ensure that the sealing strip 31 on the door panel 1 is pressed tightly.

[0091] Figure 10 A perspective view of a supporting beam-column according to an embodiment of the present disclosure is schematically shown. Figure 11 A partial enlarged view of the cover according to an embodiment of the present disclosure is shown schematically.

[0092] According to embodiments of this disclosure, such as Figure 2 and Figure 10 As shown, the supporting beam 1 includes multiple pairs of columns 11 spaced apart along its length and multiple crossbeams 12. Each pair of columns 11 faces each other in the width direction of the rail vehicle. Multiple crossbeams 12 connect adjacent columns to link the multiple pairs of columns. Figure 3 and Figure 11 As shown, the cover 2 is provided with multiple connecting brackets 23 at the positions facing the crossbeams 12 and the columns 11, so as to connect to the multiple crossbeams 12 and the columns 11 through the multiple connecting brackets 23.

[0093] As an example, such as Figure 10 As shown, multiple mounting seats 15 can be respectively provided on the crossbeam 12 and the column 11. Multiple connecting brackets 23 on the cover 2 can have through holes. The mounting seats form a threaded structure. In this way, multiple bolts can be threaded through the through holes provided on the connecting brackets 23 and screwed into the threaded structure of the multiple mounting seats 15 on the crossbeam 12 and the column 11 to realize the connection between the cover 2 and the supporting beam and column 1.

[0094] Figure 12 A cross-sectional view of a column according to an embodiment of the present disclosure is shown schematically.

[0095] Supporting beam 1 can be a metal structure, such as... Figure 12As shown, the supporting beam and column 1 can be made of thick-walled profiles, such as rectangular profiles with a plate thickness of 8mm or 10mm, which have high strength and rigidity.

[0096] The support beam 1 can be designed based on the simulation calculation results of the actual vehicle operation conditions to determine the optimal force transmission path.

[0097] Multiple crossbeams 12 and multiple columns 11 can be assembled by welding.

[0098] like Figure 10 As shown, a reinforcing part 14 can also be provided at the lower part of the column 11 to increase the rigidity and strength of the column 11.

[0099] As an example, the topmost beam 12 can be a curved beam to fit the shape of the cover 2.

[0100] like Figure 10 As shown, a reinforcing part 14 can also be provided on the upper part of the column 11, that is, the curved part connected to the crossbeam 12.

[0101] Figure 13 A cross-sectional view of a shoulder-shaped curved beam according to an embodiment of the present disclosure is shown schematically.

[0102] like Figure 9 and Figure 13 As shown, the supporting beam-column 1 also includes a shoulder curved beam 13. The shoulder curved beam 13 connects the adjacent upright column 11 and crossbeam 12. The cross-section of the shoulder curved beam 13 profile is designed according to the optimal force transmission path.

[0103] like Figure 13 As shown, the shoulder curved beam 13 includes a frame 131 and a reinforcing rib 132 disposed within the frame 131.

[0104] In this embodiment, the shoulder beam 13, which is subjected to complex stresses, is locally reinforced by built-in reinforcing ribs 132, effectively improving its bending and torsional resistance and avoiding stress concentration. The integral support beam-column 1, which is welded together, has the characteristics of structural stability and strong load-bearing capacity.

[0105] As an example, the supporting beam 1 includes a first pair of uprights 11 and a second pair of uprights arranged in front and behind along the direction of travel of the rail vehicle, and a plurality of crossbeams 12 connected to the two pairs of uprights.

[0106] The height of the first pair of uprights 11 is greater than the height of the second pair of uprights 11. Multiple crossbeams 12 include a curved first crossbeam, the two ends of which are connected to the first pair of uprights 11 via shoulder-shaped curved beams 13. The bottom ends of the first pair of uprights 11 are connected to the underframe of the vehicle body structure, and the second pair of uprights is located at the front end of the first pair of uprights. The upper part of the second pair of uprights includes a rearwardly and upwardly inclined bevel, which is connected to the first crossbeam.

[0107] The plurality of crossbeams 12 include a straight second crossbeam connected to the upper part of the second pair of uprights (e.g., connected to the inclined portion). The inclined portion of the second pair of uprights is provided with a reinforcing portion 14, and the lower part of the second pair of uprights is also provided with a reinforcing portion 14, the lower end of the second pair of uprights being connected to the base frame.

[0108] The multiple crossbeams 12 include a straight third crossbeam, which connects one shoulder bend 13 to another. Multiple connecting beams may also be provided between the third crossbeam and the first crossbeam to improve the stiffness and stability of the supporting beam-column structure.

[0109] The first crossbeam is connected to the cover body 2, and the first pair of columns are connected to the cover body 2.

[0110] According to embodiments of this disclosure, the supporting beam 1 can be connected to the vehicle body structure by welding, and the cover 2, upper cover plate 4, and lower cover plate 5 can be connected to the supporting beam 1 by bolts. Both welding and bolting techniques meet standard requirements, ensuring safety and reliability.

[0111] Figure 14 An exploded view of a skirt panel according to an embodiment of the present disclosure is shown schematically.

[0112] According to embodiments of this disclosure, such as Figure 1 , Figure 2 and Figure 14 As shown, the driver's cab also includes a skirt panel 6. The skirt panel 6 is located at the lower part of the front end of the driver's cab. The skirt panel 6 includes a pair of side skirt panels 61 and a connecting skirt panel 62. The pair of side skirt panels 61 are connected to the lower part of the cover 2. The connecting skirt panel 62 is located below the lower cover 4 and is connected between the pair of side skirt panels 61.

[0113] Skirt 6 is located below the cover 2 and lower cover 5, covering the space between the driver's cab floor and the track, serving both aesthetic and protective purposes. Skirt 6 consists of side skirts 61 on both sides and a connecting skirt 62 in the middle. The separate skirt design facilitates inspection, maintenance, and replacement. The connecting skirt 62 contributes to the aesthetic design, is independently installed, and allows for easy style changes, offering high versatility.

[0114] The separate side skirts 61 and connecting skirt 62 allow for the design of side skirt 61 as a smaller, more structurally regular part, reducing manufacturing difficulty and cost while improving production efficiency. Furthermore, during operation, the skirt 6 is easily impacted or scratched by stones or other foreign objects. With a one-piece design, even damage to a small section requires replacing the entire skirt 6, resulting in high costs and complex operations. However, with the separate side skirts 61 and connecting skirt 62, if the connecting skirt 62 is damaged, only that section needs replacement; if the side is damaged, only the corresponding side skirt 61 needs replacement. This modular maintenance approach not only reduces spare parts costs and maintenance time but also increases the uptime of rail vehicles.

[0115] The driver's cab of the rail transit vehicle according to the embodiments of this disclosure improves the strength and rigidity of the driver's cab, and achieves a high degree of integration of function and interface. It is also a novel driver's cab structure that improves the sealing performance between the driver's cab and the front escape door, as well as assembly flexibility, efficiency, and reliability.

[0116] As another aspect of this disclosure, a rail vehicle is provided, comprising a car body structure and any of the above-described driver's cabs. The driver's cab is mounted at the front end of the car body structure.

[0117] In this embodiment, the upper cover plate conceals the drive mechanism that was originally exposed above the door, thus realizing the internal design of the drive mechanism. This not only prevents the drive mechanism from being directly exposed to the external environment, effectively resisting the erosion of wind, rain, dust, etc., and improving the reliability and service life of the rail vehicle; at the same time, since the drive mechanism is internal, the opening above the escape door can be designed to be more coordinated with the door itself, avoiding the structural abruptness caused by the protrusion of the mechanism. This protects the internal mechanism of the escape door and maintains the integrity and aesthetics of the driver's compartment.

[0118] Other features of this implementation have become apparent in the above embodiments and will not be repeated here.

[0119] The embodiments of this disclosure have been described above. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of this disclosure. Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination. The scope of this disclosure is defined by the appended claims and their equivalents. Various substitutions and modifications can be made by those skilled in the art without departing from the scope of this disclosure, and all such substitutions and modifications should fall within the scope of this disclosure.
