[0002] With the development of society, urban rail transit vehicles are becoming more and more popular. The safety of vehicle door systems has received more and more attention. The anti-slip device is an important safety component in the operation of rail transit vehicle door systems. It can prevent the door leaf from slipping out of the vehicle body when the door system fails, avoiding casualties and other dangers.

[0003] The existing external sliding door leaf is hung on the bearing rail of the bearing mechanism through the bearing wheel. In the vehicle length direction, the door leaf performs reciprocating motion on the bearing rail to realize the function of opening and closing the door.

[0004] However, in the case of large passenger flow, passengers often impact the door leaf, causing the door leaf to fall off the upper guide rail during the process of opening and closing the door, which in turn causes the door leaf to get stuck and unable to open and close the door, resulting in passenger detention problems. Summary of the invention

[0023] The present invention will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-2As shown, an anti-slip external sliding door system of the present invention includes a door frame 1, a door leaf 2, a bearing mechanism 3, a driving mechanism 4, a hinge plate 5, and a lower swing arm 6. The door frame 1 is installed at the entrance of the vehicle body. When the door leaf 2 is closed and locked, the door frame 1 and the door leaf 2 realize the sealing of the door system; the bearing mechanism 3 and the driving mechanism 4 are at the upper part of the vehicle body entrance, and the bearing mechanism 3 and the driving mechanism 4 are arranged above the door frame 1 to provide power output for opening and closing the train door. A bearing guide rail is arranged on the bearing mechanism 3, and the bearing mechanism 3 is movably connected to the upper bearing guide rail of the door leaf 2 through the running wheels to realize the guiding effect of the upper part of the door leaf 2; the driving mechanism 4 is connected to the upper part of the door leaf 2 through the hinge plate 5, and the bottom of both sides of the door frame 1 is connected with the lower swing arm 6 by bolts.

[0025] like Figure 3 As shown, a first mounting frame 7 is connected to one side of the top of the door leaf 2, and a running wheel 8 is arranged on the first mounting frame 7, and the running wheel 8 is movably connected to the guide rail groove 301 on one side of the supporting mechanism 3; a hinge plate 5 is connected to the other side of the top of the door leaf 2, and an anti-slip roller 9 is arranged on the hinge plate 5, and a gap is arranged between the anti-slip roller 9 and the upper pressure strip 101 on the top of the door frame 1, and there is no contact with the upper pressure strip. When a door system fails, the door leaf falls off from the supporting mechanism, and the anti-slip roller is limited by the upper pressure strip to achieve the upper limiting function of the door leaf, so as to prevent the door system from falling off the vehicle body.

[0026] like Figure 4 As shown, the anti-slip roller 9 includes: a bearing 901, which is sleeved on the mounting hole 501 of the hinge plate 5, an eccentric shaft 902 is rotatably connected in the bearing 901, a roller 903 is arranged on the top of the eccentric shaft 902, and a nut 904 is connected to the bottom of the eccentric shaft 902.

[0027] The upper pressure strip 101 is configured as an L-shaped structure, and the gap between the anti-slip roller 9 and the vertical edge of the upper pressure strip 101 is configured as 2 mm.

[0028] The running wheel 8 is provided with a slot 801 , and the edge of the guide rail slot 301 is provided with a protrusion 302 that matches with the slot 801 .

[0029] like Figure 5 As shown, a lower door sill 102 is provided at the bottom of the door frame 1, and a door leaf lower stop 201 is provided at the bottom side of the door leaf 2. The door leaf lower stop 201 is connected to one end of the lower roller bracket 11 through a bolt 10, and a lower roller 12 is provided at the other end of the lower roller bracket 11. The lower roller 12 is movably connected to the groove of the lower door sill 102. When the door system works normally, the lower roller and the lower door sill play a guiding role at the lower part of the door leaf. When the door system fails, the door leaf disengages from the bearing mechanism, and the lower roller is limited by the lower door sill to achieve the lower limit function of the door system, so as to prevent the door system from disengaging from the vehicle body.

[0030] The bottom side of the door leaf 2 is provided with a second guide groove 202, in which a lower swing arm roller 602 of the lower swing arm 6 is movably connected, and the lower swing arm roller 602 is mounted on a lower swing arm mounting bracket 601. When in use, the lower swing arm mounting bracket of the lower swing arm is connected to the door frame, and is movably connected to the second guide groove on the side of the door leaf through the lower swing arm roller. When the door system is working normally, it can play a lower guiding role. When the door system fails, the door leaf escapes from the bearing mechanism, and the lower swing arm roller is limited by the second guide groove to achieve the limiting function of the lower side of the door system to prevent the door system from escaping from the vehicle body.

[0031] Embodiment 1:

[0032] like Figure 6 As shown, the door leaf is installed under the L-shaped upper pressure strip through the anti-slip roller on the hinge plate. When the door system fails, the door leaf will fall out of the bearing mechanism, and the anti-slip roller will be stuck in the upper pressure strip of the door frame to protect the door leaf from falling off and tipping over.

[0033] Embodiment 2:

[0034] like Figure 7 As shown, the bottom side of the door leaf is movably connected to the lower threshold of the bottom of the door frame through the lower roller on the lower roller bracket. When the door system fails, the door leaf will fall out of the supporting mechanism, and the bottom of the door frame will engage the lower roller to prevent the door leaf from falling out of the vehicle body.

[0035] Embodiment 3:

[0036] like Figure 8 As shown, the bottom side of the door leaf is also movably connected to the second guide rail groove on the bottom side of the door leaf through the upper and lower swing arm rollers of the lower swing arm mounting bracket, and the other end of the lower swing arm mounting bracket is fixed to the side of the lower part of the door frame. When the door system fails, the door leaf falls off from the supporting mechanism, and the side of the door frame is clamped with the door leaf through the clamping action between the lower swing arm roller and the door leaf, so that the door leaf does not fall off the vehicle body.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
