[0027] like Figures 1 to 5 As shown, a light rail vehicle door lower bridge device includes:

[0028] A base plate 101 is provided with a mounting groove 102 on its top surface, a cover plate 103 is provided on the top of the base plate 101, and a slide groove 104 is provided on the top of the cover plate 103. The base plate 101 is assembled in the floor at the door of the light rail carriage and can serve as a step at the door of the light rail carriage. When the light rail door is opened / closed, the door can move in the slide groove 104, thereby limiting the door.

[0029] The lap assembly is arranged in the installation groove 102, and the lap assembly includes a lap plate 201 and an assembly plate 202. The lap plate 201 and the assembly plate 202 are both located in the installation groove 102, and the lap plate 201 is located near the side notch of the installation groove 102. The assembly plate 202 is hinged on a side wall of the lap plate 201 away from the side notch of the installation groove 102. The assembly plate 202 and the lap plate 201 can achieve relative rotation around their hinge; the push-pull assembly is arranged in the installation groove 102, and the push-pull assembly includes a bidirectional screw 301. The bidirectional screw 301 is arranged in the installation groove 102 through a support 302, and a motor 3 is provided at one end of the bidirectional screw 301. 03, the motor 303 is provided to drive the bidirectional screw 301 to rotate, and a slide 304 is provided on the two spiral parts of the bidirectional screw 301 with different rotation directions. Two limit buckle plates 305 are provided on the side wall of the mounting groove 102, and the two slides 304 are both clamped in the corresponding limit buckle plates 305. The limit buckle plates 305 provided can limit the slide 304 to prevent the slide 304 from rotating with the bidirectional screw 301. One side of the two slides 304 is hinged with a linkage rod 306, and one end of the two linkage rods 306 is respectively hinged to the hinge seat of the side wall of the assembly plate 202, and the linkage rod 306 can drive the assembly plate 202 to move;

[0030] When the carriage door is opened, the motor 303 starts to drive the bidirectional screw 301 to rotate forward, prompting the two slides 304 to move closer to each other. In the process of moving closer to each other, the linkage rod 306 drives the assembly plate 202 and the lap plate 201 to move toward the side notch of the installation groove 102, prompting the lap plate 201 to move completely out so that one end of the lap plate 201 is placed on the platform, thereby covering the gap between the platform and the carriage. Moreover, since the assembly plate 202 and the lap plate 201 are hingedly connected, after the lap plate 201 is completely moved out of the notch of the installation groove 102, The lap plate 201 can rotate relative to each other around the hinge, so that the lap plate 201 is tilted and placed on the platform to meet the requirements of covering the embankment formed by the height difference between the platform and the carriage, thereby allowing wheelchair passengers or passengers carrying cargo to enter the carriage smoothly along the lap plate 201; when the carriage door is closed, the motor 303 starts to drive the bidirectional screw 301 to reverse, so that the two slides 304 can move away from each other. During the process of moving away from each other, the assembly plate 202 and the lap plate 201 can be pulled back into the installation groove 102 by the driving of the linkage rod 306;

[0031] The auxiliary support assembly is arranged in the bottom of the installation groove 102. The auxiliary support assembly includes a push plate 501 and a clamping block 503. The push plate 501 is arranged at the bottom of the assembly plate 202. The clamping block 503 is arranged in the bottom of the installation groove 102 through the assembly groove 502. The push plate 501 and the clamping block 503 are opposite to each other. A support column 504 is provided on the side of the clamping block 503 facing away from the push plate 501. A spring 505 is provided on the support column 504 between the side wall of the assembly groove 502 and the side wall of the clamping block 503. The spring 505 can normally make the support column 504 retracted into the bottom of the installation groove 102.

[0032] When the assembly plate 202 and the lap plate 201 move toward the side notch of the installation groove 102, so that the lap plate 201 extends from the installation groove 102, since the distance between the block 503 and the push plate 501 is 20mm smaller than the width of the lap plate 201, when the lap plate 201 is about to completely extend out of the installation groove 102, the push plate 501 on the assembly plate 202 can move to push the block 503, causing the spring 505 to compress so that one end of the support column 504 extends from the bottom of the installation groove 102 to rest against the bottom of the side where the lap plate 201 and the assembly plate 202 are hinged, thereby providing auxiliary support for this part, avoiding the hinge between the lap plate 201 and the assembly plate 202 from being damaged by too much force when wheelchair passengers or passengers carrying cargo enter the car along the lap plate 201, thereby ensuring the reliability of the hinge between the lap plate 201 and the assembly plate 202.
