DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0029] In addition, the present disclosure may repeat reference numbers and / or reference letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present disclosure provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0030] The technical solution of the present disclosure will be described below with reference to the accompanying drawings and specific embodiments.

[0031] Railway vehicles, such as insulated railway cars, are typically equipped with sliding, recessed doors and door frames. These doors can move along a predetermined trajectory, entering and exiting the door frame for opening and closing. This sliding, recessed door structure allows for a high degree of freedom and movement. However, there is a risk of derailment and even the risk of the door detaching from the vehicle body while the door is open, closed, or in the process.

[0032] To this end, the embodiments of the present disclosure provide a sliding embedded door and a railway insulated car, which aim to solve the problem of high derailment risk of sliding embedded doors to a certain extent, maintain the stability of the movement and locking state of the door body, and reduce the risk of accidents such as derailment or even falling of the door body.

[0033] Figure 1 shows a structural schematic diagram of a sliding embedded vehicle door according to some embodiments of the present disclosure; Figure 2 shows a structural schematic diagram of the sliding embedded vehicle door in Figure 1 from another perspective; Figure 3 shows a structural schematic diagram of the first sliding rail of the sliding embedded vehicle door in Figure 1; Figure 4 shows a schematic diagram of the coordination between the first sliding rail and the roller of the sliding embedded vehicle door in Figure 1; Figure 5 is a left view of the coordination between the first sliding rail and the roller of the sliding embedded vehicle door in Figure 4; and Figure 6 is an overhead view of the coordination between the first sliding rail and the roller of the sliding embedded vehicle door in Figure 4.

[0034] Referring to Figures 1, 2, 3, 4, 5, and 6, in some embodiments, the embedded sliding door includes a door body 11 mounted on a vehicle body 10 and movable along a predetermined trajectory to enable opening and closing. To enable the sliding of the door body 11, the embedded sliding door may further include a first slide rail 100 and a sliding support assembly 200. The first slide rail 100 is disposed on the vehicle body 10 and defines a sliding groove 110. A retaining flange 111 is provided on the groove wall of the sliding groove 110. The sliding support assembly 200 includes a roller 210. The roller 210 is rotatably connected to the door body 11 via a rotating shaft 211 and is movably disposed within the sliding groove 110. The roller 210 is prevented from disengaging from the sliding groove 110 by the groove wall and the retaining flange 111. The first slide rail 100 may be disposed on the vehicle body 10 and serves as a guide and retaining structure for the movement of the door body 11. The first slide rail 100 is provided with a sliding groove 110, and the extending direction of the sliding groove 110 is consistent with the guiding direction of the first slide rail 100. The sliding support assembly 200 includes a roller 210, which is rotatably connected to the door body 11 via a rotating shaft 211. The roller 210 is movably disposed in the sliding groove 110, so that the groove wall of the sliding groove 110 constrains and guides the moving direction of the roller 210, maintaining a stable rolling direction and posture, thereby maintaining the stability of the moving defense line and posture of the door body 11 and reducing the risk of derailment.

[0035] In some embodiments, in order to reduce the risk of the door body 11 derailing, a limiting flange 111 may be provided on the groove wall of the sliding groove 110, and the limiting flange 111 is provided along the guide direction of the sliding groove 110 to stop the roller 210 from moving in the direction of the notch of the sliding groove 110, thereby preventing the roller 210 from detaching from the sliding groove 110 and reducing the risk of the door body 11 derailing.

[0036] The sliding embedded vehicle door provided by the embodiment of the present disclosure provides a first sliding rail on the vehicle body, and provides a sliding groove and a limiting flange on the first sliding rail for accommodating a roller provided on the door body, and constraining and guiding the movement of the roller to maintain the moving posture of the door body, thereby reducing the risk of derailment; and using the limiting flange to prevent the roller from escaping from the sliding groove, thereby reducing the risk of derailment of the door body; thereby maintaining the moving posture of the roller and using the limiting flange to prevent the roller from escaping from the sliding groove, thereby reducing the risk of the door body derailing or escaping from the vehicle body as a whole.

[0037] In some embodiments, the first slide rail 100 can be integrally formed using an integrated molding process and fixed to the vehicle body 10 via a guide rail support 140 .

[0038] FIG7 is a schematic diagram showing another structure of the first slide rail of the sliding embedded door in FIG1 ; FIG8 is a left side view of another structure of the first slide rail of the sliding embedded door in FIG7 ; Referring to FIG7 and FIG8 , in some embodiments, the first slide rail 100 may adopt a split structure. The first slide rail 100 may include a first guide rail 120 and a second guide rail 130, both of which are fixed to the vehicle body 10. The first guide rail 120, the vehicle body 10, and the second guide rail 130 form the main structure of the first slide rail 100, enclosing the sliding groove 110; the limiting flanges 111 are respectively provided on the opposite side walls of the first guide rail 120 and the second guide rail 130.

[0039] The split slide rail assembly can reduce the difficulty of molding to a certain extent, thereby improving production efficiency.

[0040] In some embodiments, the groove depth direction of the sliding groove 110 can be set to be perpendicular to the guiding direction of the sliding groove 110, that is, the direction in which the roller 210 disengages from the sliding groove 110 is perpendicular to the guiding direction of the sliding groove 110; thereby, the process of the guided sliding of the roller 210 and disengagement from the sliding groove 110 can be separated, reducing the risk of the roller 210 disengaging from the sliding groove 110 during rolling.

[0041] In some embodiments, there may be two limiting flanges 111, which are relatively arranged on two opposite groove walls of the sliding groove 110, and the gap between the two limiting flanges 111 is smaller than the diameter of the roller 210 to reduce the risk of the roller 210 falling out.

[0042] 1 and 2 , in some embodiments, a space may be reserved on the vehicle body 10 to accommodate the door body 11, and a door frame 12 may be provided on the vehicle body to cooperate with the first slide rail 100 to seal and lock the vehicle body 10. Accordingly, the first slide rail 100 may be provided in an area above the door frame 12 to accommodate the roller 210 to avoid interfering with the sliding of the door body 11.

[0043] In some embodiments, in order to meet the sealing performance requirements of special vehicles such as railway insulated vehicles and improve the sealing performance of the door frame 12 area, the door body 11 can be embedded in the door frame 12, and the sealing gasket and other seals provided in the door frame 12 can be pressed to seal the gap between the door body 11 and the door frame 12.

[0044] In some embodiments, to allow for the sliding, insertion, and removal of the door body 11 from the door frame 12, the sliding support assembly 200 may further include a first crank 220 and a door pivot rod 230. The door pivot rod 230 is rotatably connected to the door body 11, with a first end of the first crank 220 connected to the door pivot rod 230 and a second end of the first crank 220 connected to the rotating shaft 211. That is, the rotating shaft 211 is not directly connected to the door body 11, but is indirectly connected to the door body 11 via the first crank 220 and the door pivot rod 230 in sequence.

[0045] When the door body 11 slides along the first slide rail 100 to a position aligned with the door frame 12, the door pivot rod 230 can be operated to drive the door pivot rod 230 to rotate, thereby causing the first crank 220 to deflect relative to the first slide rail 100, so that the door body 11 can be pushed toward the door frame 12, or pulled out from the door frame 12, and the door body 11 can be embedded in or detached from the door frame 12, thereby realizing the door opening and closing operation.

[0046] Referring to Figure 1, in some embodiments, in order to facilitate the operation of the door pivot rod 230, the sliding support assembly 200 may also include a handle 240. The handle 240 can be installed on the door pivot rod 230, and the door pivot rod 230 can be rotated relative to the door body 11 by pushing and pulling the handle 240.

[0047] In some embodiments, in order to maintain the rotation range of the door pivot rod 230, maintain the embedded position of the door body 11, and reduce the interference factors affecting the closed and sealed state of the door body 11, a locking seat 242 can be provided on the door body 11. When the door body 11 is embedded in the door frame 12 and the handle 240 follows the door pivot rod 230 to deflect to the preset locking position, the handle 240 is locked by the locking seat 242, thereby limiting the rotation of the door pivot rod 230 and achieving the locking of the door body 11.

[0048] In some embodiments, to facilitate the locking operation of the handle 240, the handle 240 can be fixed to the door pivot rod 230 via a mounting seat 241. The handle 240 can be deflected relative to the mounting seat 241 to engage with or disengage from the locking seat 242. The deflection direction of the handle 240 is perpendicular to the direction in which the handle 240 drives the door pivot rod 230 to rotate, thereby allowing for both the operation of the handle 240 to move the door pivot rod 230 and the locking operation of the handle 240.

[0049] In some embodiments, the direction in which the handle 240 moves the door pivot rod 230 can be located in a horizontal plane and perpendicular to the length direction of the door pivot rod 230; the deflection direction of the handle 240 relative to the mounting seat 241 can be in an up and down direction in a vertical plane.

[0050] Referring to Figures 4, 5 and 6, in some embodiments, considering that the roller 210 is a movable part, when it is suddenly acted upon by an external force, such as when a vehicle is hoisted for maintenance, if too much force is applied, the roller 210 may be easily forced to deform or even structurally damaged, thereby breaking through the sliding groove 110 of the first slide rail 100 and the limiting flange 111, and detaching from the first slide rail 100, causing the door body 11 to derail or even fall off the vehicle body 10 as a whole.

[0051] In some embodiments, the sliding support assembly 200 may further include a stopper 280, which may be disposed within the sliding groove 110 and connected to the rotating shaft 211. By design, the size of the stopper 280 is larger than the notch size of the sliding groove 110 and the gap size between the limiting flange 111; thereby, the rigid limiting effect of the stopper 280 allows the door body 11 to be stably engaged with the first slide rail 100 via the door pivot rod 230, the first crank 220, the rotating shaft 211, and the stopper 280, forming a reliable safety measure to prevent the door body 11 from separating from the vehicle body 10.

[0052] FIG15 is a schematic structural diagram of the first state of the stopper of the sliding embedded vehicle door in FIG1 ; FIG16 is a schematic structural diagram of the second state of the stopper of the sliding embedded vehicle door in FIG1 .

[0053] 4 , 5 , 6 , 15 and 16 , in some embodiments, considering the relatively small clearance between the sliding groove 110 and the roller 210 , in order to reduce the risk of the stopper 280 abutting against the groove wall of the sliding groove 110 and interfering with the rolling posture of the roller 210 , the stopper 280 may be configured in a fan shape. By matching the mounting position, the fan-shaped stopper 280 can abut against one of the two limiting flanges 111 in the direction of exiting the notch of the sliding groove 110 , thereby maintaining stable and reliable anti-slipping and limiting, and reducing the risk of abutting against the first slide rail 100 .

[0054] In some embodiments, along the depth direction of the sliding groove 110, that is, the direction of disengaging from the sliding groove 110, a partial area of ​​the arc-shaped side of the fan-shaped stop member 280, that is, the first stop portion 280a, can be arranged opposite to one of the two limiting flanges 111, so that the rotating shaft 211 can be restricted from disengaging from the sliding groove 110 by the first stop portion 280a.

[0055] During the operation of the door body 11 to embed or detach from the door frame 12, the stop member 280 rotates with the rotating shaft 211, so that the first stop portion 280a leaves the position opposite to the limiting flange 111, and another part of the arc side of the fan-shaped stop member 280, namely the second stop portion 280b, replaces the first stop portion 280a and is opposite to the limiting flange 111, limiting the rotating shaft 211 from detaching from the sliding groove 110, thereby maintaining the stability of the stopping function.

[0056] 5 and 6 , in some embodiments, to prevent the roller 210 from moving along the first slide rail 100 and from escaping from the sliding groove 110, a stopper 150 may be provided in the sliding groove 110. The stopper 150 may be provided at the end of the set travel path of the roller 210 to stop the roller 210.

[0057] 1 and 2 , in some embodiments, in order to improve the sliding stability of the door body 11, a second slide rail 300 may be provided on the vehicle body 10, and the sliding support assembly may further include a second crank 250 and a support roller set 260. The first end of the second crank 250 is connected to the door pivot rod 230, and the second end is connected to the support roller set 260. The support roller set 260 is slidably provided on the second slide rail 300, so that the weight of the door body 11 can be mainly carried by the support roller set 260, forming a second stable sliding support structure under the door body 11 to enhance the sliding posture and position stability of the door body 11.

[0058] FIG11 is a schematic structural diagram of the door limiting mechanism of the sliding embedded vehicle door in FIG1 ; FIG12 is a schematic structural diagram of the door limiting mechanism of the sliding embedded vehicle door in FIG1 from another perspective.

[0059] Referring to Figures 1, 2, 11 and 12, in some embodiments, since the door body 11 can slide flexibly under the support of the roller 210 and the support roller group 260, it is very easy to slide freely under the interference of external factors when the door body is open, causing safety risks and even derailment and falling risks. To this end, the sliding support assembly 200 may also include a door limiting mechanism 270, which is connected between the second slide rail 300 and the support roller group 260, and can connect and lock the support roller group 260 to the second slide rail 300, limiting the movement of the support roller group 260 on the second slide rail 300, thereby locking the door body 11 and preventing it from sliding freely and causing collisions, derailment or even falling risks.

[0060] In some embodiments, the locking position of the door body 11 by the vehicle door limiting mechanism 270 can be set to the storage position when the door body 11 is fully opened, thereby avoiding mutual interference between goods and people entering and exiting the door frame 12, and ensuring the safety of goods, people and the door body.

[0061] In some embodiments, the door limiting mechanism 270 may include a limiting support 271, a limiting lock rod 272 and a hook seat 274. The limiting support 271 can be installed on the second slide rail 300, and the hook seat 274 is installed on the support roller group 260. The limiting lock rod 272 can be deflectedly connected to the limiting support 271, and a hook body 272a is provided on the limiting lock rod 272, so that when the hook seat 274 follows the support roller group 260 to move to the storage position of the door body 11, the limiting lock rod 272 can be deflected to make the hook body 272a hook on the hook seat 274, thereby limiting the free sliding of the support roller group 260 and the door body 11.

[0062] The hook body 272a can be arranged toward the hook seat 274, and during the opening process of the door body 11, it slides along the second slide rail 300 and gradually approaches the limit lock rod 272; after the door body 11 moves into place, the hook body 272a and the hook seat 274 are in a corresponding locking position, and by operating the limit lock rod 272, the hook body 272a can be stably locked to the hook seat 274.

[0063] In some embodiments, to enhance the convenience of locking the door stop mechanism 270, the door stop mechanism 270 may further include an elastic return member 273. The elastic return member 273 may be connected between the second slide rail 300 and the stop lock rod 272, exerting an elastic force between the stop lock rod 272 and the second slide rail 300 to maintain the stop lock rod 272 in a predetermined locked position. Thus, when the hook 272a is hooked onto the hook seat 274, the elastic force exerted by the elastic return member 273 maintains the stop lock rod 272 in the locked state, reducing the risk of unhooking and unlocking. To unlock, an operator can deflect the stop lock rod 272, causing the hook 272a to disengage from the hook seat 274.

[0064] When the hook body 272a is not hooked on the hook seat 274, that is, when the locking state is not maintained, the limiting lock rod 272 is also maintained in the locked position due to the elastic force of the elastic return member 273. When locking is required, the limiting lock rod 272 can be operated to deflect and lift the hook body 272a. After the hook seat 274 is in place, the limiting lock rod 272 is released. The locking rod 272 is automatically reset under the elastic force of the elastic return member 273, and the hook body 272a is stably maintained in the state of being hooked on the hook seat 274.

[0065] 11 and 12 , in some embodiments, to enhance the efficiency and convenience of locking the door 11, a push-receiving inclined surface 272b may be provided on a side of the hook body 272a proximate to the hook seat 274. When the hook seat 274 approaches and contacts the hook body 272a, a pushing force is generated on the push-receiving inclined surface 272b that deflects the limit lock rod 272, causing the limit lock rod 272 to deflect and lift the hook body 272a. When the hook seat 274 moves to a predetermined locked position, the hook seat 274 no longer pushes against the push-receiving inclined surface 272b, and the hook body 272a is at a predetermined height. The hook body 272a can then automatically return to its original position under the elastic force of the elastic return member 273, maintaining the hook body 272a stably hooked on the hook seat 274. That is, a collision locking mode is formed between the hook body 272a and the hook seat 274, and no additional manual operation of the limit lock rod 272 is required, thereby improving the efficiency and convenience of locking.

[0066] In some embodiments, a pushing inclined surface 274a that cooperates with the pushed inclined surface 272b can be opened on the hook seat 274. When the hook seat 274 contacts the hook body 272a, the surface contact between the pushed inclined surface 272b and the pushing inclined surface 274a can reduce the severity of the impact on the hook body 272a, and achieve smooth locking, so as to avoid the situation where the hook body 272a cannot be accurately positioned and locked on the hook seat 274 due to excessive deflection of the limit lock rod 272, thereby improving the reliability of locking.

[0067] In some embodiments, the hook seat 274 can be configured as an annular member, and the hook body 272a can be accommodated through the hollow area of ​​the annular member to achieve a simple locking functional structure.

[0068] In some embodiments, the elastic return member 273 may include a support link 273a and a return spring 273b, the support link 273a may be slidably connected to the second slide rail 300, the first end of the support link 273a is movably connected to the limit lock rod 272, the return spring 273b is sleeved on the support link 273a, and the two ends of the return spring 273b are respectively connected between the second slide rail 300 and the second end of the support link 273a, so that the deformation direction of the return spring 273b is constrained by the support link 273a to form a stable elastic return force.

[0069] In some embodiments, the support link 273a may be pivotally connected to the limiting lock rod 272 to ensure a stable connection state and reduce the risk of interference between the deflection movement of the limiting lock rod 272 and the linear movement of the support link 273a.

[0070] In some embodiments, the support link 273a can move back and forth along a set straight line trajectory. To this end, guide holes, guide grooves, guide brackets and other structures can be set on the second slide rail 300 to constrain and guide the movement of the support link 273a.

[0071] FIG9 shows a schematic structural diagram of the anti-slip mechanism of the sliding embedded vehicle door in FIG1 ; FIG10 shows a schematic structural diagram of the anti-slip mechanism of the sliding embedded vehicle door in FIG1 from another perspective.

[0072] Referring to Figures 1, 2, 9 and 10, in some embodiments, considering the risk of functional abnormality of the locking structure of the door body 11, in order to cope with the situation where the door body 11 is embedded in the door frame 12 and falls out, the sliding embedded vehicle door may also include an anti-slip mechanism 400, which is connected between the door body 11 and the vehicle body 10 as a safety anti-slip measure to reduce the risk of the door body 11 falling off.

[0073] In some embodiments, the anti-slip mechanism 400 may include a stop seat 410 and an anti-slip lock tongue 420, wherein the stop seat 410 is arranged on the vehicle body 10, and the anti-slip lock tongue 420 can be deflectedly arranged on the door body 11, so that when the door body 11 is embedded in the door frame 12, the anti-slip lock tongue 420 can be deflected and embedded in the stop seat 410 to form an anti-slip functional structure in the form of a door bolt, connecting the door body 11 to the vehicle body 10, and limiting the door body 11 from being separated from the door frame 12.
