[0028] The present application discloses an embodiment of a vehicle boarding and alighting assistance device, comprising: a first plate body 1, a second plate body 2 and a lifting mechanism.

[0029] Among them, two fixing mechanisms are installed on the first plate body 1. Taking one of the fixing mechanisms as an example, the fixing mechanism includes a first baffle 11 and a second baffle 12. The first baffle 11 and the second baffle 12 are both installed on the base plate and there is a distance between them. The first baffle 11 is vertically hinged to the base plate through a rotating shaft. A baffle groove 13 is opened on the base plate. The first baffle 11 can be vertically rotated toward the second baffle 12 and be completely received in the baffle groove 13.

[0030] The first resetting member is used to drive the first baffle plate 11 away from the second baffle plate 12 , and also includes a limiting structure, which is used to limit the first baffle plate 11 from rotating away from the second baffle plate 12 to a maximum of being perpendicular to the substrate.

[0031] In a specific embodiment, the first reset member is a torsion spring sleeved on the rotating shaft of the first baffle 11, one end of the torsion spring is connected to the substrate, for example, it can abut against the substrate, and the other end is connected to the first baffle 11, for example, it can abut against the first gear lever 11, and the torsion spring can drive the first gear lever 11 away from the second baffle 12.

[0032] The limiting structure includes an arc groove 14 opened along the circumference of the rotating shaft of the first baffle 11, and a fixed limiting block 15, which extends into the arc groove 14. For example, the limiting block 15 can be a side wall of the baffle groove 13, and a corner of the limiting block 15 close to the arc groove 14 extends into the arc groove 14. When the first baffle 11 rotates toward and away from the second baffle 12, the limiting block 15 is used to block and limit the arc groove 14.

[0033] The second baffle 12 is slidably matched with the substrate. The second baffle 12 can be close to or away from the first baffle 11 . The second baffle 12 also includes a second reset member, which is used to drive the second baffle 12 to approach the first baffle 11 .

[0034] In a specific embodiment, a slide groove is provided on the base plate, and the bottom end of the second baffle 12 is slidably matched with the slide groove, and the second baffle 12 can move closer to or farther from the first baffle 11 along the slide groove. The second return member is a return spring 16, which is arranged in the slide groove, and one end of the return spring 16 is connected to the slide groove, and the other end is connected to the second baffle 12.

[0035] In the embodiment disclosed in the present application, the second plate body 2 is arranged below the first plate body 1, and the first plate body 1 and the second plate body 2 are horizontally rotatably matched. In one example, the middle part of the first plate body 1 is rotatably matched with the middle part of the second plate body 2 through a rotating shaft.

[0036] In the embodiment disclosed in the present application, the lifting mechanism is used to drive the second plate body 2 to rise and fall. The present application provides a more specific lifting structure, for example, the lifting mechanism includes a rack 31 fixed to the side edge of the second plate body 2 and arranged vertically, and a gear 32 meshing with the rack 31, and a driving mechanism for driving the gear 32 to rotate, wherein the driving mechanism can be but is not limited to a motor, and specifically when installed in a carriage, the gear 32 can be embedded in the side wall of the carriage, and a sliding groove body can be reserved on the side wall of the carriage for the rack 31 to rise and fall, and the gear 32 can be driven to rotate by the driving mechanism, so that the second plate body 2 can be driven to rise and fall, and then the first plate body 1 can be driven to rise and fall.

[0037] In addition, in order to facilitate the adjustment of the distance between the two fixing mechanisms, at least one fixing mechanism can be close to or away from the other fixing mechanism. In a specific example, a slide rail 4 is provided on the substrate, and the substrate in at least one fixing mechanism is slidably matched with the slide rail 4. For example, both fixing mechanisms can be slidably matched with the slide rail 4, and at this time, both fixing mechanisms can move to achieve mutual approach or distance. When only one substrate in a fixing mechanism is slidably matched with the slide rail 4, the other fixing mechanism is fixedly installed on the first plate body 1, and it needs to be located above the slide rail 4 or on the extension line of the slide rail 4, so that one fixing mechanism can be close to or away from the other fixing mechanism when sliding.

[0038] When the present application is working, the first plate 1 is first rotated to make the first baffle 11 face toward and approach the wheelchair. At this time, the wheelchair user operates the wheelchair to roll toward the second baffle 12. Since the first baffle 11 can be rotated toward the second baffle 12 and stored in the baffle groove 13, the wheelchair wheel can press down the first baffle 11 to press the first plate into the baffle groove 13. When the wheelchair wheel passes over the first baffle 11 and is located between the first baffle 11 and the second baffle 12, the first reset member drives the first baffle 11 to reset and move away from the second baffle, and the second reset member drives the second plate toward the wheel. The wheels of the chair move and abut against the wheels of the wheelchair. At this time, the wheels of the wheelchair are clamped by the first baffle 11 and the second baffle 12. Then, the lifting mechanism drives the second plate 2 and the first plate 1 to descend. When the first plate 1 reaches a position level with the platform, the first plate 1 is rotated again to make the first baffle 11 face the direction of getting off. At this time, the wheelchair user operates the wheelchair to push the second baffle 12 away from the first plate 11, leaving a rotation gap for the first baffle 11. At this time, pressing down the first baffle 11 can cancel the clamping of the wheels, and the wheelchair can leave the vehicle through the first baffle 11.

[0039] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
