[0024] Figure 1 This is a structural schematic diagram of the end baffle of a railway freight car according to some embodiments of this specification. Figure 2 This is a structural schematic diagram of the side panel of a railway freight car according to some embodiments of this specification.

[0025] like Figure 1 , Figure 2 As shown, some embodiments of this specification provide a railway freight car 10 including a floor 100, two end baffles 200, two side baffles 300, and a top baffle.

[0026] The base plate 100 serves as the mounting foundation, supporting the two end baffles 200, two side baffles 300, and a top baffle. In some embodiments, the base plate 100 is a plate-like structure. In some embodiments, the base plate 100 can be a one-piece molded structure. In some embodiments, the base plate 100 can be a structure formed by splicing multiple parts. In some embodiments, the bottom of the base plate 100 is provided with multiple rollers, which can be rolled in connection with the rails. When the rollers rotate, they can drive the base plate 100 to move along the rails.

[0027] The two end baffles 200 are along the length of the base plate 100 (e.g., Figure 2 The end baffles 200 (in the Y direction) are located at both ends of the base plate 100. In some embodiments, the end baffles 200 are plate-shaped structures. In some embodiments, the end baffles 200 and the base plate 100 can be connected in various ways, such as welding, snap-fitting, threaded connection, integral molding, etc. The length direction of the end baffles 200 is parallel to the width direction of the base plate 100 (e.g., in the Y direction). Figure 1 (in the X direction).

[0028] Two side baffles 300 are disposed on both sides of the base plate 100 along the width direction of the base plate 100. In some embodiments, the side baffles 300 are plate-shaped structures. In some embodiments, the side baffles 300 and the base plate 100 can be connected in various ways, such as welding, snap-fitting, threaded connection, integral molding, etc. The length direction of the side baffles 300 is parallel to the length direction of the base plate 100.

[0029] In some embodiments, the two end baffles 200 are alternately connected to the two side baffles 300, and the two end baffles 200 surround each other to form a receiving space. In some embodiments, the end baffles 200 and the side baffles 300 can be connected in a variety of ways, such as welding, snap-fitting, threaded connection, integral molding, etc.

[0030] A top baffle is located above the receiving space, and the top baffle can have an open state and a closed state. When the top baffle is open, objects can be placed into the receiving space. For example, containers or goods to be transported can be placed there.

[0031] In some embodiments, the top baffle includes a first baffle 410 and a second baffle 420. The first baffle 410 and the second baffle 420 are combined to form the top baffle. In some embodiments, the length directions of the first baffle 410 and the second baffle 420 are parallel to the length direction of the base plate 100, respectively. In some embodiments, the first baffle 410 and the second baffle 420 are detachably connected.

[0032] In some embodiments, the first baffle 410 and the second baffle 420 may be movably connected to the end baffle 200, respectively. This movable connection may include a sliding connection and / or a rotational connection. When the first baffle 410 and the second baffle 420 are slidably connected to the end baffle 200, the direction of movement of the first baffle 410 and the second baffle 420 may be parallel to the width direction of the base plate 100. When the first baffle 410 and the second baffle 420 are rotatably connected to the end baffle 200, the center of rotation of the first baffle 410 and the second baffle 420 may be parallel to the length direction of the base plate 100.

[0033] In some embodiments, the first baffle 410 and the second baffle 420 move towards each other, which can close the top baffle. Moving towards each other means that the first baffle 410 and the second baffle 420 move towards each other. Moving away from each other means that the first baffle 410 and the second baffle 420 move away from each other, which can open the top baffle. Moving away from each other means that the first baffle 410 and the second baffle 420 move away from each other.

[0034] In some embodiments, the base plate 100, end baffle 200, side baffle 300, and top baffle may be made of the same material, such as steel. In some embodiments, at least one reinforcing structure, such as a reinforcing rib or reinforcing rib plate, may be provided on at least one side of the base plate 100, end baffle 200, side baffle 300, and top baffle.

[0035] When the top baffle is open, it facilitates the loading of goods or containers from the top of the storage space into the storage space by lifting structures such as gantry cranes and cranes. After installation, the top baffle can be closed promptly to facilitate subsequent transportation. The top baffle is formed by the combination of the first baffle 410 and the second baffle 420. By moving and / or rotating the first baffle 410 and the second baffle 420, the opening and closing of the top baffle can be easily and conveniently controlled, and the space occupied by the first baffle 410 and the second baffle 420 when open can be reduced, avoiding interference with the operation of other structures when the first baffle 410 and the second baffle 420 are open.

[0036] Figure 3 yes Figure 1 Enlarged diagram of point A.

[0037] In some embodiments, such as Figure 1 , Figure 3 As shown, the end baffle 200 is provided with at least two connecting structures. The connecting structures are connected between the first baffle 410 and the end baffle 200, and / or connected between the second baffle 420 and the end baffle 200.

[0038] The connection structure is used to drive the first baffle 410 and / or the second baffle 420.

[0039] The following example uses the connection structure corresponding to the first baffle 410.

[0040] In some embodiments, the connection structure includes a first groove 520, a first slider 510, and a first connecting rod 530.

[0041] A first groove 520 is disposed on the end baffle 200 to guide the movement of the first slider 510. In some embodiments, the length direction of the first groove 520 is parallel to the vertical direction of the end baffle 200 (e.g., Figure 1 (Z direction in the text). In some embodiments, the first groove 520 may be located near the edge of the end baffle 200. In some embodiments, the cross-section of the first groove 520 may include various shapes, such as at least one of rectangular, dovetail, T-shaped, and trapezoidal shapes. The cross-section of the first groove 520 refers to the virtual cross-section formed after the first groove 520 is cut off by a plane perpendicular to the vertical direction of the end baffle 200.

[0042] The first slider 510 is slidably disposed within the first groove 520, and the first slider 510 can slide along the length direction of the first groove 520. In some embodiments, the first slider 510 can form sliding friction or rolling friction with the first groove 520. In some embodiments, at least a portion of the first slider 510 can be adapted to the cross-section of the first groove 520. For example, the cross-section of at least a portion of the first slider 510 can be at least one of a rectangle, a dovetail shape, a T-shape, a trapezoid, etc. Using shapes such as dovetail, T-shape, and trapezoid can increase the connection strength between the first slider 510 and the first groove 520.

[0043] The first connecting rod 530 is used to transmit force. In some embodiments, the first connecting rod 530 is connected between the first baffle 410 and the first slider 510. One end of the first connecting rod 530 is rotatably connected to the first baffle 410, and the other end of the first connecting rod 530 is rotatably connected to the first slider 510. When the first slider 510 can move along the length direction of the first slide groove 520, the first slider 510 can drive the first connecting rod 530 to rotate and drive the end of the first connecting rod 530 connected to the first slider 510 to move. The first connecting rod 530 drives the first baffle 410 to move, thereby switching the top baffle between an open state and a closed state. In some embodiments, when the first slider 510 is located at the top of the first slide groove 520, the top baffle is in a closed state. When the first slider 510 is located at the bottom of the first slide groove 520, the top baffle is in an open state.

[0044] In some embodiments, the connecting structure corresponding to the second baffle 420 may be the same as the connecting structure corresponding to the first baffle 410, and they are symmetrically distributed. The first connecting rod 530 corresponding to the second baffle 420 is connected between the second baffle 420 and the first slider 510 corresponding to the second baffle 420.

[0045] In some embodiments, the railway freight car 10 may further include a first drive structure, which outputs power to move the first slider 510 within the first slide rail 520. In some embodiments, the first drive structure may include at least one of a motor, a hydraulic cylinder, an electric pusher cylinder, etc. In some embodiments, a transmission structure may be provided between the first drive structure and the first slider 510, such as a gearbox. In some embodiments, the first drive structure may be located at the bottom of the base plate 100 to avoid the first drive structure occupying part of the space within the accommodating space, thus reducing the amount of goods that can be transported. The first drive structure drives the first slider 510 to move, and then drives the first baffle 410 or the second baffle 420 to move via the first slider 510 and the first connecting rod 530, which facilitates placing the first drive structure at a lower position, thereby lowering the center of gravity of the first drive structure, improving the stability of the first drive structure, and avoiding the risk of the first drive structure falling.

[0046] In some embodiments, two connecting structures located on the same end baffle 200 can share a driving structure. One driving structure can simultaneously drive the two first sliders 510 to move synchronously, thereby making the first baffle 410 and the second baffle 420 move synchronously. This helps to simplify the structure and reduce production and usage costs.

[0047] In some embodiments, the railway freight car 10 may further include a processor, which can be used to analyze, store, and process data. In some embodiments, the processor can be communicatively connected to a drive structure, and the processor can control the start or stop of the drive structure, thereby achieving remote and automated control. In some embodiments, multiple drive structures can be communicatively connected to their respective processors. In some embodiments, multiple drive structures can share a single processor.

[0048] In some embodiments, such as Figure 2 As shown, a second connecting rod 540 connects the first baffle 410 and the first slider 510.

[0049] The second link 540 is used to transmit force. When the first slider 510 moves, the first slider 510 can apply a force to the side of the first baffle 410 near the side baffle 300 through the second link 540.

[0050] In some embodiments, at least a portion of the first link 530 and at least a portion of the second link 540 are elastic. When the first slider 510 moves downward along the first groove 520, the first slider 510 can pull the first link 530 and the second link 540, causing the elastic portions of the first link 530 and the second link 540 to extend, and driving the first baffle 410 to move outward through the first link 530. The second link 540 can apply a downward pulling force to the outwardly extended portion of the first baffle 410, enabling the first baffle 410 to rotate. When the first slider 510 moves to the bottom of the first groove 520, the second link 540 can pull the first baffle 410, causing the first baffle 410 to abut against the side baffle 300. This further reduces the space occupied by the first baffle 410 and avoids interference with other structures during the opening or closing process of the first baffle 410. In some embodiments, when the first slider 510 moves to the bottom of the first groove 520, the first connecting rod 530 forms an acute angle with the vertical direction. When the first slider 510 moves upward, it can more easily push the first connecting rod 530 to move, thus preventing the first connecting rod 530 from getting stuck.

[0051] In some embodiments, at least a portion of the first link 530 may employ an elastic structure, such as a spring, to make at least a portion of the first link 530 elastic. In some embodiments, the first link 530 may include at least one first rigid link and at least one first spring, the at least one first rigid link and at least one first spring being interconnected to form the first link 530.

[0052] In some embodiments, at least a portion of the second link 540 may employ an elastic structure, such as a spring, to make at least a portion of the second link 540 elastic. In some embodiments, the second link 540 may include at least one second rigid link and at least one second spring, which may be interconnected to form the second link 540. By making at least a portion of the first link 530 and the second link 540 elastic, the elastic portions of the first link 530 and the second link 540 adaptively deform during movement, thereby preventing jamming.

[0053] In some embodiments, a second connecting rod 540 is connected between the second baffle 420 and the corresponding first slider 510. The second connecting rod 540 corresponding to the second baffle 420 has the same structure as the second connecting rod 540 corresponding to the first baffle 410 and is symmetrically distributed.

[0054] In some embodiments, the length direction of the first slide groove 520 can be arc-shaped, such as a circular arc, an elliptical arc, or other arc shapes, and the specific shape can be set according to actual needs. The arc-shaped opening can face the top of the end baffle. By adopting an arc-shaped first slide groove 520, when the first slider 510 moves within the first slide groove 520, the first connecting rod 530 and the second connecting rod 540 can be better guided to rotate, avoiding jamming.

[0055] In some embodiments, one end of the second link 540 corresponding to the first baffle 410 is rotatably connected to the first baffle 410. And / or, one end of the second link 540 corresponding to the second baffle 420 is rotatably connected to the second baffle 540. The other end of the second link 540 is rotatably connected to the corresponding first slider 510. This rotatable connection of the second link 540 allows it to rotate adaptively during the movement of the first slider 510, thereby preventing jamming.

[0056] In some embodiments, the first slider 510 can be an L-shaped structure, with one end of the first slider 510 extending into the first groove 520 and slidably connected to the first groove 520. The other end of the first slider 510 is disposed towards the outside of the end baffle 200 and rotatably connected to the second connecting rod 540. This helps to avoid interference between the second connecting rod 540 and other structures.

[0057] In some embodiments, a connecting structure is provided at each end of the first baffle 410. The connecting structures at both ends of the first baffle 410 can synchronously control the movement of the first slider 510, thereby enabling better control of the opening or closing of the first baffle 410.

[0058] In some embodiments, a connecting structure is provided at each end of the second baffle 420. The connecting structures at both ends of the second baffle 420 can synchronously control the movement of the first slider 510, thereby enabling better control of the opening or closing of the second baffle 420.

[0059] Figure 4 This is a partial schematic diagram of the end of the first baffle shown in some embodiments of this specification.

[0060] In some embodiments, such as Figure 3 , Figure 4 As shown, the first baffle 410 has a second groove 430 at at least one end facing the end baffle 200, and the end baffle 200 has a second slider 210 adapted to the second groove 430. The length direction of the second groove 430 is parallel to the width direction of the base plate 100 (e.g., Figure 1 (in the X direction). In some embodiments, the second slider 210 is slidably connected to the second groove 430.

[0061] The second slide 430 works in conjunction with the second slider 210 to guide the movement of the first baffle 410 and prevent the first baffle 410 from detaching from the end baffle 200, thereby improving the stability of the first baffle 410.

[0062] In some embodiments, the second baffle 420 has a second groove 430 at at least one end facing the end baffle 200. The structure of the second groove 430 corresponding to the second baffle 420 may be the same as that of the second groove 430 corresponding to the first baffle 410.

[0063] In some embodiments, such as Figure 4 As shown, the bottom of the first baffle 410 is provided with a stepped portion 440. The second slide groove 430 is provided on the end face of the stepped portion 440 facing the end baffle 200.

[0064] A stepped surface is formed between the stepped portion 440 and the first baffle 410. In some embodiments, the stepped surface may be a concave stepped surface. The stepped portion 440 may engage between the two end baffles 200. The lower surface of the first baffle 410 may abut against the top surface of the end baffle 200, thereby reducing the pressure on the second slider 210. This prevents the second slider 210 from deforming under pressure and affecting the movement between the first baffle 410 and the end baffle 200. In some embodiments, the stepped portion 440 may be an elongated protrusion, and the length direction of the stepped portion 440 may be parallel to the width direction of the base plate 100. This can reduce the overall weight of the first baffle 410.

[0065] In some embodiments, the bottom of the second baffle 420 is provided with a stepped portion 440. The structure of the stepped portion 440 corresponding to the second baffle 420 may be the same as that of the stepped portion 440 corresponding to the first baffle 410.

[0066] In some embodiments, such as Figure 3 As shown, the first baffle 410 extends beyond the side baffle 300 on the side facing the side baffle 300, and the step portion 440 below the first baffle 410 extends beyond the side baffle 300 on the side facing the side baffle 300. The end baffle 200 has protruding connecting brackets on both sides along the width direction of the base plate 100, and the second slider 210 can be mounted on the connecting brackets. In some embodiments, the distance between the second slider 210 and the end baffle 200 can be greater than or equal to the distance between the second slider 210 and the bottom surface of the step portion 430. By providing connecting brackets, sufficient space can be reserved for the rotation of the first baffle 410. When the first baffle 410 rotates, it can rotate around the second slider 210, preventing the first baffle 410 from disengaging from the second slider 210.

[0067] In some embodiments, the second baffle 420 extends beyond one side of the side baffle 300. The second baffle 420 may have the same structure as the first baffle 410.

[0068] In some embodiments, the portion of the second slider 210 extending into the second groove 430 may be cylindrical, thereby preventing the second slider 210 from obstructing the rotation of the first baffle 410 or the second baffle 420.

[0069] In some embodiments, the connection between the second link 540 and the first baffle 410 is located at the portion of the first baffle 410 extending beyond the side baffle 300 along the width direction of the base plate 100. The connection between the second link 540 and the second baffle 420 is located at the portion of the second baffle 420 extending beyond the side baffle 300 along the width direction of the base plate 100. This allows for a more rational distribution of the second link 540, helping to prevent jamming.

[0070] Figure 5 This is a schematic diagram showing the connection between the first baffle and the second baffle according to some embodiments of this specification.

[0071] In some embodiments, such as Figure 5 As shown, the first baffle 410 has a connecting protrusion 411 on the side facing the second baffle 420, and the second baffle 420 has a connecting groove 421 on the side facing the first baffle 410. The connecting protrusion 411 can be adapted to the shape of the connecting groove 421. When the first baffle 410 and the second baffle 420 move towards each other, the connecting protrusion 411 can extend into the connecting groove 421. By utilizing the cooperation between the connecting protrusion 411 and the connecting groove 421, the movement direction of the first baffle 410 and the second baffle 420 can be guided when they move towards each other, improving the connection accuracy between the first baffle 410 and the second baffle 420, and also enhancing the sealing strength between the first baffle 410 and the second baffle 420.

[0072] In some embodiments, a sealing layer may be provided on the surface of at least one of the connecting protrusion 411 and the connecting groove 421, which can further enhance the sealing performance when the connecting protrusion 411 and the connecting groove 421 are connected. The sealing layer can be made of various materials, such as rubber, silicone, etc.

[0073] Figure 6 This is an installation diagram of a container according to some embodiments of this specification. Figure 7 This is a partial schematic diagram of a container according to some embodiments of this specification.

[0074] In some embodiments, such as Figure 6 , Figure 7 As shown, the railway freight car 10 also includes at least one container 600.

[0075] Container 600 is a container structure that can be opened or closed. Container 600 can be used to load goods. In some embodiments, container 600 can be a cubic structure. Container 600 can be made of various materials, such as at least one of metal, wood, etc. In some embodiments, container 600 has at least one hook-and-loop structure on its top. The hook-and-loop structure is used to connect to a transportation system, which may include a gantry crane, crane, etc. In some embodiments, the hook-and-loop structure can be detachably connected to a hook of the transportation system. When the hook-and-loop structure is connected to the hook, the transportation system can move container 600. In some embodiments, the hook-and-loop structure may include at least one of at least one hook, groove, slot, etc., structure provided on the top of container 600.

[0076] In some embodiments, the container 600 is detachably mounted on the base plate 100.

[0077] In some embodiments, at least one first magnetic structure 110 is provided on the base plate 100, and at least one second magnetic structure 610 is provided on the bottom of the container 600. The first magnetic structure 110 and the second magnetic structure 610 can be magnetically connected.

[0078] In some embodiments, the first magnetic attraction structure 110 may include a permanent magnet. In some embodiments, the first magnetic attraction structure 110 may include an electromagnet. In some embodiments, the first magnetic attraction structure 110 may be communicatively connected to a processor, which can remotely and automatically control the first magnetic attraction structure 110 to generate or stop generating magnetic force. When the first magnetic attraction structure 110 generates magnetic force, it can attract the second magnetic attraction structure 610, thereby positioning and guiding the container 600 during transportation, avoiding safety risks associated with manual adjustment of the container 600's position. Using the first magnetic attraction structure 110 to guide the positioning of the container 600 can also improve the positioning accuracy of the container 600 and subsequent installation accuracy. In some embodiments, multiple first magnetic attraction structures 110 may be provided, for example, 4, 6, or other numbers, the specific number can be set according to actual needs. Multiple first magnetic attraction structures 110 may be evenly distributed in an array on the base plate 100. The number of second magnetic attraction structures 610 is the same as that of the first magnetic attraction structures 110, and the distribution pattern may be the same.

[0079] In some embodiments, the second magnetic structure 610 may include a permanent magnet or a magnetic metal, such as iron, nickel, etc.

[0080] In some embodiments, such as Figure 7As shown, at least one fixing block 120 is provided on the base plate 100, and the fixing block 120 is slidably provided on the base plate 100. The container 600 is provided with a connecting part 620, and the fixing block 120 is engaged with the connecting part 620.

[0081] The fixing block 120 serves to restrict the connecting portion 620. For example, it restricts the degree of freedom of movement and / or rotation of the connecting portion 620, thereby improving the stability of the container 600 and preventing displacement of the container 600. In some embodiments, the fixing block 120 may be connected to a drive structure, which may include at least one of a motor, a hydraulic cylinder, etc. The drive structure can drive the fixing block 120 to move on the base plate 100.

[0082] The connecting portion 620 is used to connect with the fixing block 120. In some embodiments, the fixing block 120 is snapped into the connecting portion 620. In some embodiments, the connecting portion 620 may include at least one of various structures, such as a protrusion, a groove, a slot, etc. In some embodiments, the fixing block 120 may apply pressure to the connecting portion 620, thereby restricting the degree of freedom of movement and / or rotation of the connecting portion 620.

[0083] By way of example only, the connecting part 620 may be a protrusion protruding from the container 600, and the fixing block 120 may be an L-shaped structure. The fixing block 120 may be fastened above the connecting part 620, thereby applying downward pressure to the connecting part 620.

[0084] In some embodiments, multiple connecting parts 620 may be provided and distributed around the circumference of the container 600, and the number of fixing blocks 120 is the same as that of the connecting parts 620 and they are provided accordingly.
