[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1 Reference Figures 1 to 4 In one embodiment of the present utility model, an underground trackless vehicle passenger access device is provided. This underground trackless vehicle passenger access device includes a vehicle 7 and a boarding device. A fixing plate 1 is fixedly installed inside the vehicle 7 to support the entire boarding device and fix the boarding device to the vehicle 7.

[0025] Specifically, the loading device includes multiple connecting rods 3 for folding and unfolding the loading device, with every four connecting rods 3 forming a parallelogram structure. A fixing element 4 is provided at the connection point of adjacent connecting rods 3. The fixing element 4 only serves to fix and connect the connecting rods 3, without tightening them, allowing the connecting rods 3 to fold. The fixing element is a combination of bolts and nuts. A handle 2 for unfolding the loading device is fixedly installed on one of the connecting rods 3 connected to the fixing plate 1. The parallelogram mechanism formed by the connecting rods 3 can be manually adjusted in unfolding height according to the ground level to accommodate different loading heights.

[0026] Specifically, the boarding device includes a support rod 5 located at the bottom of the boarding device. When the boarding device is extended, the support rod 5 contacts the ground to support the boarding device. The boarding device also includes a footboard 6 for people to step on when getting on and off the vehicle. The footboard 6 is fixedly connected between mutually parallel horizontal connecting rods 3 to form a support surface.

[0027] Specifically, a connecting groove is provided at the bottom of the carriage 7, and the top of the handle 2 passes through the connecting groove and is placed inside the carriage 7. Two sets of boarding devices are provided, symmetrically arranged inside the carriage 7.

[0028] During use, move handle 2 out of the carriage 7, the connecting rod 3 unfolds, and when the support rod 5 touches the ground, the boarding device is placed stably on the ground. Personnel step on the pedal 6 to enter the carriage 7, and then move handle 2 in the opposite direction to retract the boarding device.

[0029] Example 2 Reference Figure 5A drive block 12 is slidably installed at the bottom of the carriage 7. A slot is opened at the bottom of the drive block 12. A rail is fixedly installed at the bottom of the carriage 7. The slot is movably connected to the rail. The drive block 12 can only move because it is restricted by the rail at the bottom of the carriage 7. A moving slot 8 is opened on the side of the drive block 12. The moving slot 8 does not penetrate the drive block 12. A connecting post 9 is fixedly installed on the handle 2. The connecting post 9 is movably installed in the moving slot 8. The moving slot 8 is a slot that is inclined upward away from the front of the car. When the drive block 12 moves, the moving slot 8 drives the connecting post 9 inside it to move, thereby driving the handle 2 to rotate.
